Is it possible to carry out an extract into the ventilation holes. Kitchen hood with outlet to ventilation and its installation. How to connect an exhaust device to a ventilation rack

The smell of food is good in the kitchen. The cozy living room smells of flowers, perfumes, but fried potatoes. Cooker hoods can perfectly capture heat, steam and kitchen fumes or burn electricity for nothing.

All kitchen hoods are divided into two categories: with connection to the ventilation shaft and autonomous. Properly selected and correctly connected to the ventilation shaft, the hood will not disappoint the owners.

Types of kitchen hoods

By installation, the following types of kitchen hoods are distinguished:

hinged(standard and flat) - mounted under a shelf or wall cabinet over the stove;
embedded- built into the cabinet body or a specially constructed decorative box;
wall-mounted- hung directly on the wall, they are distinguished by a variety of designs;
corner- for installation in the corner of the kitchen;
insular- hung on the ceiling above the kitchen "island".

Functionality of ventilation hoods

Operating modes of hoods:

outflow. Kitchen hood with the withdrawal of the entire volume of exhaust air into the ventilation. It is connected to a ventilation shaft or exhausts air outside through a special hole in the wall. Hot wet air and unwanted aromas are removed from the apartment, providing a 100% effect.
Filtration. These are hoods without connection to ventilation. The air, filled with vapors and aromas of the kitchen, enters the filter and, cleaned, is sent back. Filters are located inside the housing, they need to be changed or washed periodically.

Filtration or recirculation mode greatly simplifies installation. You do not have to decide how to bring the hood into the ventilation. At the same time, the performance of the equipment is noticeably reduced.

The filtration of the hood for the kitchen with a drain is made with sintepon, coal, paper, non-woven, acrylic or metal filters.

Dense carbon filter reduces engine power.

The rules for installing the hood without a vent to the ventilation, as well as how to properly connect the hood to the ventilation, read on.

Extraction performance

This indicator primarily affects the quality of indoor air treatment. Productivity determines the volume of air passed in 1 hour.

According to sanitary requirements in the kitchen, it is necessary to provide 12-fold air exchange.

We use the formula:

Rx V x 12 x 1.3

where R- kitchen area 1,3 - equalizing factor, 12 - air exchange rate, V- room height.

Choose models with a capacity exceeding the calculated by 10 - 15%.

Hood noise level

AT modern dwellings The kitchens are adjacent to the bedrooms and living rooms, so the noise level is very important. A constantly buzzing hood will cause headache and fatigue.

The more powerful the hood, the noisier it is. But responsible manufacturers (for example, BOCSH, Siemens, Samsung) manage to special form blades, installation of twin fans and additional sound insulation to achieve fairly quiet operation with impressive performance.

For reference, noise levels in different rooms, in decibels:

in a quiet room 30 ;
whisper of a man 35 ;
the best hoods or quiet music - 40 ;
human speech at a distance of 2.5 and the noise of an average quality hood - 50 .

Do not purchase a hood with a noise level above 50 decibels. She will disturb the tenants of the apartment. The best hoods emit a noise of 44 decibels, and when maximum power no more than 70.

To reduce noise as much as possible, models with an external motor have been developed. The engine is placed at the outlet of the duct. These are kitchen hoods connected to ventilation.

Additional options

Lighting. This function is supplied to the vast majority of kitchen hoods connected to ventilation and autonomous. There are models with a change in the brightness of the light, focusing the beam. Equipped with a motion sensor, turn on the light when the hostess approaches.

Touch control panel and display. Convenient, but doable. The display shows the operating mode, and the touch panel is much easier to keep clean than protruding mechanical buttons or sliders (sliders).

Rules for installing the hood

Installation and connection requires knowledge of a number of rules:

the body is hung only in level, with careful observance of the horizontal;
the distance between the electric hob and the hood must be 65 cm;
the distance between the gas hob and the hood is no more than 75 cm;
the bend of the duct for connecting the hood with ventilation does not exceed 90 degrees;
when the length of the duct is more than 3 m, a second fan is installed to maintain the draft;
when bringing the kitchen hood into the ventilation, it is forbidden to block the ventilation outlet in the wall;
pipes of the same section are used, since aerodynamic noise increases with narrowing;
if the kitchen hood is vented, it is advisable to install a valve that prevents back draft.

Before connecting the kitchen hood to the ventilation, you should read the instructions for it.

Connecting the hood to the ventilation riser

Before connecting the hood with ventilation, take care of all necessary components. To connect a kitchen hood with a vent to the ventilation, corrugation or smooth round PVC ducts with elbows are used. The second option is preferable, as it creates less air resistance, smooth inner surface easier to clean. The pipe diameter is not less than 120 mm, it is selected according to the outlet section of the hood. For fixing the air duct, the hood is equipped with an adapter.

The air duct must have no more than 3 elbows, otherwise the work efficiency will be significantly reduced.

Most often, for the correct connection of the hood to the ventilation, it is necessary to stretch the box and hermetically strengthen the end of the duct in the ventilation duct.

Connecting the kitchen hood to the ventilation will not block the vent if you install a special grill.

The throughput of general house ventilation is from 110 to 140 cubic meters of air per hour. Extraction power can be 180 - 700 cubic meters per hour.

Before you bring the hood into the ventilation, consider the possibility of bringing the duct into a specially made hole in the wall. Otherwise, a working device may cause a “tipping” of thrust. A phenomenon that is especially dangerous in houses with gas heating appliances leading to carbon monoxide poisoning.

The air ducts are joined hermetically, and a check valve and a grid are installed at the outlet.

After the hood is brought into the ventilation, it is connected to the mains. Requires a standard voltage of 220 - 240 V and a frequency of 50 Hz. Sometimes a ground is connected to the outlet, eliminating the possibility of a short circuit.

The main task when installing a hood without connecting to ventilation is to correctly place and supply electricity.

Installation and connection in the kitchen of the hood has long been no less a necessity, as well as the installation of a gas stove or refrigerator. A kitchen hood is able to keep furniture and kitchen surfaces from dirt, and is also needed to clean the air in the room.

Three main types of hoods used in the kitchen.

The principle of operation of exhaust devices and types of hoods

The method of connection and operation of the exhaust device depends on its type and principle of operation. There are exhaust systems that do not even need to be connected to ventilation, since they work offline.

Scheme of connecting the hood to ventilation

At the moment, according to the principle, several types of exhaust devices are distinguished.

First, these are classic or domed hoods that remove polluted air through a ventilation system. Secondly, recirculation hoods are increasingly coming into use, the principle of which is that they suck in exhaust air, pass it through filters and return it back. And, thirdly, these are combined hoods that can work both in exhaust mode and in filtering mode.

According to the method of installation, there are much more varieties of exhaust devices. These include:

Built-in, installed directly in the kitchen furniture. To this species usually include devices of recirculation and classical type;
Suspended, which are attached to the kitchen cabinet directly above hob. They can only be exhaust systems of a recirculation type;
Wall-mounted, which are mounted above the stove on the wall. Such a design is possessed by devices of classical and combined type;
Island, mounted to the ceiling above the hob if it is located in the center of the kitchen. Usually they are systems of a combined and classic type;
Corner. They look like corner design and work according to the classical or combined type.

Determining the type and power of the kitchen hood

When purchasing an exhaust system, its dimensions should be taken into account: area working surface hoods should not be less area according to a certain algorithm and its main points include:

The presence and location of the vent, but not in the situation with recirculation systems, where such a factor does not play any role;
Determining the type of stove or hob;
Taking into account the diameter of the exhaust adapter that connects the system to the ventilation duct.

The required power of the hood is selected, in accordance with the width of the exhaust adapter. The narrower the hole, the more power the device needs.

Table for determining the required extractor power in m 3 / hour for the kitchen area and ceiling height

Such a choice is an exclusively individual matter, but the acquisition of a powerful device is not always justified. The system is selected according to the diameter of the ventilation duct, and in the case of a powerful device, a decent amount of electricity will be spent, and the efficiency will remain low. A significant amount of air sucked in by a powerful hood cannot be pushed through a narrow ventilation channel. According to statistical results, the maximum performance of the device is created at low fan speeds.

Tools and materials for mounting the hood

Mounting the hood, like many household chores, will require the use of a certain set of tools. It is better to prepare them in advance, so that later you do not waste time searching. You will need:

Drill or perforator. Much will depend on exactly where the wall will need to be drilled: if in interior partition- then a drill is also suitable, if in concrete floor- then you can’t do without a perforator;
Screwdriver;
Roulette and building level;
A hammer.

Rules for installing the hood

There is nothing difficult in the installation of an exhaust device in the kitchen. In the presence of the right tools and certain skills it can be mounted on your own in just a few hours. Before installation, it would be a good idea to read the attached instructions.

For each type of exhaust devices, there are general rules installation.

To begin with, the distance from the hood to the stove must be at least 75 cm for a gas stove and at least 65 cm for all other types of stoves. At a shorter distance, your exhaust system may begin to melt. There is no maximum installation height, the main thing is that the user should be comfortable using it.

Advice: If the exhaust system will exhaust air into the ventilation, the duct must be laid with a minimum number of bends. It must be borne in mind that each angle of 90 degrees reduces the efficiency of the device by at least 10%.

Ideally, the air duct in the kitchen should preferably be made of plastic. Plastic is much easier to disguise, and it looks much more aesthetically pleasing. corrugated pipes. Among other things, the corrugation can hum during operation. To reduce the noise level, such pipes must be stretched as much as possible during installation.

The hood must necessarily be grounded, this is required by elementary safety rules. In progress exhaust device encounters high temperature steam and condensate when hot air is cooled. This means that the hostess or any of the residents is at risk of getting hit. electric shock in the absence of grounding.

The procedure for installing the exhaust device

Consider the installation procedure for exhaust systems, depending on the type of mounted hood.

Installing a classic hood

It is quite possible to install a classic-type exhaust device in the kitchen on your own. The hood is usually mounted after installing the entire kitchen furniture. Therefore, even when ordering a kitchen wall, you will first need to leave a place for the exhaust device.

The first step is to think about how the duct will be laid in the kitchen, and how you will disguise it. In the case of a classic hood, the air duct will most likely be on top of the cabinets. In such a situation, the corrugation can be hidden behind decorative panels.

Next, you need to proceed to the installation of fasteners. Since dome hoods weigh quite a lot, they are usually installed on dowels. Drill or punch holes in the wall and insert dowels. Then install the support on which the hood will be mounted.

After installing the hood, you must connect the duct. In classic exhaust systems, it is attached from above. Take your time to attach the duct to your home ventilation. Before the final stage, it is necessary to carefully control the operation of the device, namely the presence of traction. If everything is as it should, the hood is connected to the ventilation duct, and the duct is masked.

Installing a built-in hood

Installation this device has some difficulties. But in terms of aesthetics, the built-in hood is in no way inferior to a flat recirculation hood, and in terms of power a standard dome hood. The built-in exhaust system differs from the domed one in the absence of an external casing, which performs a purely decorative function and hides the "insides" of the device. At correct installation such a hood is practically invisible in the kitchen. This option is ideal in a kitchen made in a classic or rustic style, where the presence of fashionable and modern devices not very appropriate. In the situation with the installation of a built-in hood in the kitchen, only its control panel catches the eye.

A built-in hood is installed above the stove with a hidden air duct.

Such devices are built directly into the kitchen furniture, which is the main difficulty in their installation. and here, for installation, certain skills and abilities will be needed. A built-in hood is installed in a cabinet designed specifically for this, which is mounted directly above the stove. It will be very nice if the locker is made to embed the system. But it is possible to use the most ordinary cabinet. If you have a regular wall cabinet, just temporarily remove all the shelves and its bottom. It is worth installing additional fasteners to make the cabinet more rigid. Also in its upper part you will need to make a hole for attaching the duct. This hole is easily made with an ordinary jigsaw.

After preparing the cabinet, you can proceed to the installation of the hood itself. As in the case of the classic type, we fasten the supports to the dowels, mount the hood, install the cabinet. After installing the exhaust device, we fix the air duct and arrange a check of the operation of the hood.

The purchase of such equipment will become meaningless if the guests see a corrugation visible in the kitchen. One of the options for hiding the duct from the eyes is to lay a corrugated pipe inside the kitchen furniture. It is also possible to mount a plastic air duct in kitchen wall. Or use decorative panels to hide.

Installing a recirculation hood

Recirculating exhaust devices are the easiest to install. The principle of their operation is based on air filtration, which means the complete absence of an air duct. This hood is mounted to the wall of the kitchen. The disadvantages of recirculating exhaust devices include their relatively low power and the need to replace carbon filters in them twice a year.

The principle of operation of the recirculation hood in the kitchen.

Hood mount

To mount a certain type of hood on a wall, in a corner, on a cabinet or on the ceiling, there are fasteners that are included with the purchase. For correct fastening hoods, it is important to strictly follow the instructions included in the kit. To drill holes in the surface for attaching the hood, you must attach the module, make markings with a level, and then start drilling holes.

Connecting the hood in the kitchen to the ventilation shaft

For dome or combined type hoods, an indispensable condition is the installation of a ventilation duct or corrugated pipe. It doesn't depend on distance in any way. exhaust opening from the hob and the installation site of the exhaust module. Their connection is required.

Connection to ventilation in the wall with non-return valve.

To connect the hood to the ventilation are used:

corrugated pipes, which are used in situations where it is possible to hide it from human eyes;
polypropylene pipes, assembled from complete modules and having different shapes.

To connect the adapter pipe, you need a grille the size of the ventilation duct with a hole for the adapter. The pipe is attached to the ventilation hole and to exhaust system through a variety of clamps and sealants. Diameter connecting pipe is selected in accordance with the diameter of the outlet of the hood and the ventilation hole.

Connecting the hood in the kitchen to electricity

At first it seems that the connection process is simple, but there are some nuances in it.

If the installation of the device was not considered during the last repair work, there is a possibility that the power cord may be too short to plug into the nearest outlet.

You can use a carrier, but it is a temporary option. The socket can be installed both on the wall and on the surface of the cabinet. You just need to determine the location of the socket with maximum accuracy, taking into account that it should not be located next to the sink or stove.

The most acceptable option for installing an outlet will be a place hidden from prying eyes above the kitchen modules.

Any novice master will be able to cope with the choice, installation and connection of the hood. enough to follow correct order actions and strictly follow the instructions. And you will certainly succeed.

The smell of food is good in the kitchen. The cozy living room smells of flowers, perfume, but not fried potatoes. Cooker hoods can perfectly capture heat, steam and kitchen fumes or burn electricity for nothing.

Types of kitchen hoods

By installation, the following types of kitchen hoods are distinguished:

Hood - necessary element in the kitchen. It quickly cleans the air from droplets of grease, moisture and unpleasant odors. With the advent of the hood, cleaning will take less time, since all of the above will no longer settle on the surface of furniture, walls and kitchen appliances. Also, the smell of fried cutlets, fish and other food will not spread throughout the apartment. The air will become clean, fresh and pleasant, which will improve the atmosphere in the house. After all fresh air- the guarantee of health.

Kitchen hood ensures cleanliness

Varieties of kitchen hoods

In order to choose such household equipment as correctly as possible, you need to know what kind of hoods for the kitchen are and how they differ. First of all, kitchen hoods, as well as all other models of such household equipment differ in the way of fastening:

Island.
Embedded.

An island-type hood is attached above a separate kitchen "island" - this is when hob with an oven do not come into contact with the wall, but stand separately, in the middle of the kitchen. The hood is attached to the ceiling with a cable or pipe. Air duct leading to ventilation.

Usually the air duct is built under false ceiling, for a more presentable look. In shape, island hoods are in the form of a hemisphere, rectangular, oval, and so on. The dome-shaped hood, due to its shape, captures more smoke and fumes, which is why it is in demand. Island hoods are made to order.

Built-in hood is in great demand

Built-in hoods are gaining momentum in popularity, as kitchens in apartments are usually modest in size. This type of hood has a built-in sliding panel, with which the size of the hood is increased. For this reason, built-in hoods are called compact. Mount the hood in the hinged Kitchen Cabinet or in a decorative box, resulting in technical part camouflaged, which makes the interior neat.

Kitchen hood with outlet

An air duct is connected to this type of hood, which goes into ventilation duct. Also, the air duct is laid to a hole made in outer wall. Air with particles of grease, as well as smoke and other vapors, pass through the filter in the hood. Fat settles on the filter grates and the fan parts do not clog, which prolongs the life of the exhaust device. Also, the air masses passing through the hood filters are partially cleaned, which is why they do not harm the environment.

The choice of hood depends on the microclimate in the home. For this reason, the installation of an exhaust structure must be thought out to the smallest detail. Kitchen hood with outlet to ventilation perfect option for a small eatery.

Pros and cons of hoods with a vent to the ventilation

ease of operation (filter maintenance without cost and effort);
performance (filter coarse cleaning has little resistance).
high level of purification: the air is purified from smoke, soot, unpleasant odors and other impurities.

there should be a good flow of air from the street, but if there is no draft, then they install powerful fans, which will solve this problem;
installation difficulties (an air duct is connected, and if a ventilation duct is not provided, then a hole is made in the outer wall).

When choosing an exhaust structure, you should pay attention to the filters, and choose the option for yourself.

Types of filters and their characteristics

For all types of hoods, there are only two filtering options:

Metal filters for the hood do not require replacement

Metal filters that precipitate up to 95% of contaminants. The filter is also replaced aluminum foil with perforation. The filter does not need to be changed. Can be simply rinsed hot water with detergent.
Synthetic disposable filters are discarded after use.

Exhaust control panels

Modern models of household hoods have two types of panel control:

sensory;
push-button.

The touch panel contains a built-in sensor that records air humidity and temperature. If the indicators change, then the device changes the mode. It is a pleasure to use this setup.

The mechanical control panel is practical and affordable. It is important that the buttons are placed in front of the panel, as setting desired mode will be simpler.

Enclosure selection

Cases are made from three types of material:

The most affordable of them is a metal case covered with enamel. The appearance of such equipment is beautiful, but it requires careful care.
Polished panel of stainless steel – expensive option. Looks stylish and easy to clean.
The third type of panels is made from tempered glass. It looks fashionable, but after washing, stains remain on the glass.

Features of the installation of the exhaust structure

When installing a kitchen hood with a vent to the ventilation, you need to know some rules that will help you install the exhaust system with high quality and reliability.

When installing the hood with your own hands, many nuances should be taken into account

The body of the device is leveled so that all horizontal lines are observed.
The bend of the duct at the junction of the ventilation duct and the equipment must not exceed 90 degrees.
If the length of the duct is more than 3 meters, then it is necessary to install another fan to improve air exchange.
The distance between the appliance and the hob should be 75 centimeters.
The duct pipes must be the same size. If on one side there is an expansion or narrowing of the pipe, then the noise in them will increase.
To avoid reverse thrust, a damper must be installed in the system.

How to choose the right hood size

The hood in the kitchen should be the same size as the stove or slightly larger. If the size of the device is smaller than expected, then it will not cope with the task. There will be little use for such equipment. Lighting

Lighting is supplied to a large number modern models kitchen appliances. There are also models of hoods with light balance adjustment, and are also equipped with a motion sensor, including light on human movement.

Noise level in the ventilation system

Often kitchens are adjacent to the hall or to other rooms. For this reason, the ventilation sound level is important.

The noise of the hood directly depends on the power. The stronger, more powerful the device, the louder it works. But some manufacturing firms have managed to create models that are quiet and powerful.

Sound level is measured in decibels. To explain what range the sound is, consider examples:

Human whisper -35.
In an empty room -30.
Human speech at a distance of 2.5 meters -50.

It is not recommended to buy a model where the sound level is 60 decibels or higher, as the noise will interfere with the residents of the house. Ideally, it is better to choose a model that produces a sound of 44 decibels. Also, to reduce noise, hoods with an external motor were invented, and the motor is located at the end of the duct. This type of hood is connected to ventilation.

How to connect an exhaust device to a ventilation rack

Before connecting the hood to the ventilation, prepare everything you need. To combine the hood with the outlet to the ventilation tunnel, corrugation or round PVC ducts are used.

Option number two is more suitable, as it creates a small resistance with air. PVC pipes are also easier to maintain. Pipe in diameter, 130 millimeters. Pick it up on the notch of the hood at the exit. An adapter is used for connection. For correct connection the hood and air duct must be tightened and the end of the air pipe must be fixed in the ventilation duct. When connecting the hood with a channel, the connection will not close the ventilation gap if a protective grill is installed.

ventilation ducts

With the design of the hood, the volume of air in the kitchen should change - 10 times. To do this, we find the correct ratio between the power of the installation and the size of the kitchen.

The calculation is as follows: the length of the kitchen is multiplied by the width and height. We multiply the resulting number by 10. This number is productivity. But if a corrugated pipe is used in the arrangement of the channel, then another 40 percent must be subtracted, since pipe irregularities reduce the power of the air flow. Also, all the bends in the pipe reduce the force of the air flow by 10 percent. This means that when installing ventilation ducts, it is required not to bend the pipes at a right or sharp angle. For the reason that an obtuse angle does not give such resistance as a sharp or straight one.

The mistake is that they do not know about the need for air handling units with warm air recovery. This is necessary so that negative pressure does not form in the apartment. Because of this, the hood will no longer function normally, since it has nothing to pump out. The bottom line is that dirty air will leave, but clean air will not be able to enter. Therefore, all points must be considered and planned. Recovery systems heat up the cold air stream in winter time due to the outgoing heat.

When purchasing a hood, you should think about the fact that there are a lot of nuances in its installation. The installation scheme must be correctly planned to the smallest detail. And seek help from a specialist.

Another nuance is the pipe under the air duct, although of large diameter, but the performance of the ventilation path is determined by the narrowest point along the length.

If the corrugated pipe bends, then the channel will narrow, and this diameter will determine the patency of the entire structure. Because of this, it is desirable to control the work of the masters.

In the process of cooking, the kitchen is filled with steam and the smells of food. All this is absorbed into the walls, headsets and negatively affects the well-being of people in the room. Installing a kitchen hood with a vent to the ventilation will ensure the full collection and discharge of exhaust air with negative volatile components.

The article presented by us describes in detail the device of hoods that communicate with ventilation systems. The principle of action is thoroughly analyzed, negative and positive sides are given. To help home craftsmen, recommendations are attached on the selection and installation of exhaust equipment.

The variety of hoods offered by manufacturers is sometimes amazing. On the market, you can easily find the optimal model in terms of cost and quality.

But for an unprepared buyer, the choice and installation of such kitchen appliances become a difficult and sometimes overwhelming task. Therefore, before going to the store or installing the hood, in without fail it is necessary to deal with all the subtleties and nuances.

Sanitary norms and requirements

Any type of hood, whether recirculating or a device with a vent to the ventilation, must drive out an air volume equal to 10-12 volumes of the cooking room in one hour.

It's tough sanitary requirement which must be fulfilled. After all, sources are actively used in the kitchen open fire, heating appliances. And the humidity in the room is much higher than in other rooms.

As a result, the concentration of carbon dioxide harmful impurities and evaporation is constantly increasing, which will negatively affect the well-being of a person.

In the case of using a device connected to ventilation, it is necessary to ensure the flow of oxygen from the street. If this factor is not taken into account, then the effect of capsizing will appear. Its essence is that the air will be drawn from the duct back to the kitchen

Another requirement is that the hood should be installed as close to the hob as possible. This is a minimum of 65 cm for an electric stove and 75 cm for a gas stove.

A prerequisite is the presence of a special grate on the device, where dirt and grease will settle. This prevents waste from entering the ventilation duct.

Extractor hood with ventilation

Hoods that remove exhaust air through the ventilation shaft are the classic and most familiar models for most people. Thanks to the constant flow fresh air a person's mood rises, well-being improves, and his stay in the kitchen will become more comfortable.

Usually exhaust devices provide forced ventilation what the fan is used for. This approach allows for shortest time take out of the room excess moisture which can harm furniture set, unpleasant odors, various fumes, soot, excess carbon dioxide, etc.

In order not to pollute the atmosphere around the house, the hoods use a special filter that collects most of all the dirt.

The hood sucks in the exhaust air and removes it from the room, for which the ventilation shaft of the house or apartment is used.

The only drawback of built-in is the complexity of their installation. After all, the device must be connected to the duct. If the house does not have a ventilation duct, then you will have to drill a hole in the wall.

Varieties of hoods with a branch

There are several types of such kitchen appliances. Hoods with a vent to the ventilation are divided into categories depending on the design of the device, the method of installation and cleaning.

By type of installation, the following devices are distinguished:

Mounted. They are divided into domed or flat. And on the market there are inclined products, which, if necessary, can be decomposed. The hinged hood will harmoniously fit into large kitchen, and in a small room.
Embedded. Devices of this type are ideal solution for small apartments. Their peculiarity lies in the fact that they are built into the locker and act as its bottom. Some devices can be moved apart to increase the amount of air that is taken in.

Kitchen owners large area prefer the island design of the exhaust device. It is used in situations where the stove is located not at one of the walls of the kitchen, but in the center of the room. Island hoods are attached directly to the ceiling and allow you to create original design premises.

Among other things, the exhaust air extractor is important element kitchens. It not only absorbs harmful fumes, but also acts as a decorative element. Therefore, choosing one or another type, you need to evaluate whether the desired model will be in harmony with the design of the kitchen.

It is necessary to choose one or another type of hood depending on the location of the stove and the dimensions of the kitchen.

Selection criteria for exhaust device

The hood is one of the main elements of any modern kitchen. Therefore, her choice must be approached with all responsibility. In order not to miscalculate and buy the best device, you need to pay attention to the whole characteristics inherent in these devices.

Among the criteria influencing the choice are the following:

the size;
operating modes;
type of filter used;
Availability additional features;
case material;
performance;
noise;
way to control the device.

Certainly, optimal size extremely important when choosing a device. It directly depends on the dimensions of the cooking surface. So before going to the store household appliances you should definitely know it.

In order for the hood with air exhaust to the ventilation to cope with its main task, its dimensions must necessarily correspond or be slightly more area gas stove. Thanks to this, the appliance will take the maximum amount of fumes from the kitchen, which will significantly increase its efficiency.

As for the choice of operating mode, here you need to decide which device is needed. The fact is that the hoods can operate in the modes of recirculation and air exhaust through the ventilation shaft, or combine 2 options.

The best solution would be to buy combined model. If the choice fell on the last variety, then you need to ask the seller about the cost and availability of filters.

Extractor hoods are more economical and practical solution. After all, recirculation devices need regular replacement of filters.

Before buying, you need to see which filters are used in the hood you like. They are designed to collect most of the grease and dirt. There are several types of filters. The best solution are metal mesh. They are versatile and easy to care for - they can be easily washed.

The article, the contents of which we recommend that you read, will familiarize you with the device and varieties for a kitchen hood.

As for plates made of synthetic material, then this is not the most the best choice- They cannot be washed. Such products will have to be changed regularly, and this is an additional cost. After they have served their time, you will have to go to the store and buy new ones.

The metal grills can be easily removed and put back into the hood. Therefore, there will definitely not be any problems with cleaning a device where such filtration is used.

Among the additional functions of hoods, the most useful and practical is the interval mode of its operation. It must be in any hood. This means that the device will turn on from time to time, purify the air and then turn off.

In the vast majority of mid-range models, an electronic timer is used to implement this function. As for more expensive products, their interval mode is based on the use of sensors that analyze the composition of the air. But such a highlight will significantly increase the cost of the hood. Therefore, before buying, you have to think carefully: is this function worth it?

All exhaust devices differ significantly in the material of the body. Manufacturers offer kitchen appliances with air outlet through ventilation made of enamel, tempered glass or stainless steel.

Before choosing a particular material, you need to remember that durability depends on it, appearance and, of course, the cost of the device. Therefore, it is important to consider all the positive and negative sides each of them.

The main advantage of enameled and metal surfaces is their low cost. In addition, they are easy to clean and wash with a brush. Their presentable appearance should be added to the list of features of models whose case is made of stainless steel - such devices can not be built into a cabinet.

When it comes to tempered glass hoods, these models look simply chic and cost accordingly. At the same time, to keep them clean, you will have to regularly and carefully care for them. Yes, and handle such equipment should be as careful as possible.

Glass hood is a great design solution. Such a device will fit perfectly into any design, whether it be luxury classic or strict modern

Looks don't always match. internal content. This statement also applies to kitchen hoods. Indeed, today it is easy to purchase, the power of which is not enough to purify the air even in a small kitchen.

In order not to miscalculate with the choice, it is necessary to calculate in advance the optimal performance of the device. To do this, you should find out the volume of the kitchen - multiply the floor area by the height of the ceilings.

For comfortable work in the room, you need to buy a hood, which in 5-6 minutes can completely renew the air in the room. That is, in an hour the device should have time to make 10-12 such cycles. To find out the hood performance required for your kitchen, you should multiply the volume of the room by the air exchange rate (10-12).

For example, if we take small room with an area of 15 m 2, where the ceiling height is 3 meters, then by multiplying these values, we get a volume equal to 45. We multiply this number by the air exchange rate and adding 20% as a margin, we find out the optimal hood power for such a kitchen. In this example, the productivity of the device should be equal to 450-540 cubic meters per hour.

In order not to burden yourself with calculations, you can use the table above. It contains all the information about the optimal hood power for a particular kitchen.

The noise of the device plays important role- Housewives often spend several hours, and sometimes half a day, on cooking. Some even install TVs in the kitchen so they don't miss their favorite movie, series or show.

It hardly needs to be said that a noisy hood will not allow you to concentrate and will not let you hear what the heroes of the melodrama are talking about. Therefore, in order to determine the optimal model for yourself, you need to deal with decibels.

The volume of normal human speech is 50-60 dB, while for quiet music this figure does not exceed 40 dB. As for the hood, you should look at the noise level in its technical data sheet. It should be in the range of 40-80 dB.

The volume of the hood is directly related to its performance. Accordingly, than more powerful device the more noise it will create

When choosing an exhaust device, it is important to pay attention to how it is controlled. There are three types of buttons - touch, mechanical and combined. The cheapest, simplest and most reliable are mechanical models. In this case, the power is regulated using a number of special buttons or a slider (movable slider).

The touch display requires only a light touch. These hoods look modern. The advantage of touch models is the ease of care for them. Due to the absence of protruding elements, dirt from the display can be easily removed with a damp cloth.

Hybrid models, unlike touch and mechanical ones, are not as popular. Here, the buttons are completely recessed into the case, so they can only be felt. But on the other hand, caring for hybrid devices is just as easy as for touch ones.

Manufacturers offer hoods with multifunction displays. A small screen displays all the information about the operation of the device

When choosing a particular model, be sure to pay attention to the lighting option. In inexpensive hoods, they use ordinary light bulbs incandescent. Although they are cheap, they burn out much more often. At the same time, such lighting consumes a large amount of electricity.

It is better to give preference to models that use halogen lamps. They are a more economical alternative, and they shine much brighter. But keep in mind that in such lighting, food will take on an unnatural look.

The ideal option is LED bulbs. They require a minimum amount of electricity and last for years.

A distinctive feature of hoods with air extraction into luxury ventilation is the presence of motion sensors. Thanks to this constructive solution the light turns on if activity has been noticed in the area of the hob.

Some models also allow you to dim or, conversely, enhance the lighting. This makes cooking comfortable at any time of the day or night.

Apart from specifications, it would be useful to read the reviews of other buyers about a particular model. Numerous users who have already ordered this or that hood and managed to use it will point out the advantages and disadvantages of a particular product. This approach will allow you to weigh the pros and cons and get the best hood for your kitchen.

When searching for reviews, trust only trusted sites that contain both positive and negative opinions about the product.

Rules for connecting the hood

Choosing and buying a hood suitable for your kitchen with air exhaust into the ventilation shaft is only half the battle. It is important to properly install the device. In order not to make mistakes, it is necessary to follow a certain sequence of actions.

First, immediately after purchase, you need to check the complete set of the device. The box must contain technical certificate, where there is an installation manual, an exhaust device and a set of fasteners (self-tapping screws and anchors for mounting to a brick wall).

Then it is important to prepare everything for work - a building level, a puncher or drill, a tape measure and a screwdriver. Then determine and mark, which depends on the type of plate and its dimensions.

using a tape measure, measure about 70-80 cm above the hob and draw a horizontal line using a level;
in the center of the previously drawn line, draw another one perpendicular to it;
with help masking tape fix the template on the wall so that it does not move when drilling;
then, with a drill and a drill corresponding to the self-tapping screws included in the kit, four holes are made in the wall;
screws should be screwed into the wall so that their head protrudes 0.5 cm;
after that, remove the grill and cover from the hood and hang it on the fasteners;
now it remains to tighten the screws to the end in order to securely fix the device on the wall.

Installation ends with the installation of the cover and grille. Then follows the most important and time-consuming stage - the organization of ventilation. But subject to all the rules and recommendations, the process will not cause absolutely no difficulties.

It is better to entrust the installation of an expensive hood to a professional. The specialist will do everything as quickly and accurately as possible

Selection and installation of ventilation ducts

There are two types of ventilation pipes for the hood - this and. The latter variety is in great demand, as it has many advantages.

The advantages of corrugated pipes include:

Ease of installation. The product is made of thin aluminum, so that the corrugation can be bent and rotated as required.
The ability to quickly change the length. If the pipe turned out to be too long, then the excess can be cut off with ordinary scissors. And when the calculations were carried out incorrectly, then the corrugation can be increased without any problems - the elements are quickly and well connected to each other.
light weight. The material is very light, thanks to which you can save on additional fasteners and reduce the time required for ventilation installation.
Cheapness. A buyer with any income level can afford to buy corrugation.

But when installing this material, you need to be extremely careful. After all, the corrugation is very pliable and strong pressure can leave an ugly dent on the product.

It is generally recommended to use plastic ventilation pipes. This kind of product has a smooth inner surface, so that the flow will not slow down against the walls and lose its speed. In addition, the material is characterized by low cost, the absence of elements subject to oxidation, as well as safety for human life and health.

To connect the air duct to the ventilation with your own hands, you need to connect the plastic flange of the hood with a corrugation or plastic pipe, insert the same element into the ventilation grill and fasten the entire structure with construction clamps

Where is the best place to place an outlet?

The extractor hood consumes a considerable amount of electricity during its operation. Therefore, experts recommend that a separate line be drawn for the device, since, otherwise, the entire network may not withstand such voltage.

The socket should be located directly near the device itself. Please note if cooking is used gas stove, then the socket must be at a safe distance from it.

Rules for the care of the hood

In order for the device to serve for a long time, it must be cleaned regularly. Before washing the hood, it must be de-energized. Next, you need to remove the grill or filter and wash all parts of the device on which dirt could accumulate. For cleaning, you can use dish detergent or special composition designed for stainless steel products.

hallmark modern materials is the ease of washing them. But sometimes, in case of severe contamination, you need to use a detergent. Please note that it is forbidden to use powder, a metal sponge or a washcloth with a rigid fiber structure for cleaning - they will scratch the surface of the hood.

To wash the buttons, use a soft cloth soaked in a cleaning solution. After all the elements of the hood are perfectly cleaned and the surface of the device is wiped dry, the device can be plugged into the outlet and continue to operate.

The period of its use directly depends on the quality and regularity of washing the hood. If you pay due attention to this, then the device will faithfully serve for more than one year, and even after 5 years, it will look like new.
