Dimensions of built-in hoods. We understand the features of built-in kitchen hoods

Modern kitchens without fail are completed with an extract. No, this is not a tribute to fashion or tradition. The lack of exhaust equipment in the room leads to the fact that fat fumes and soot settle directly on work surfaces and furniture.

As a result, the kitchen is more often in need of time-consuming cleaning. Despite the variety of hoods that the market offers, built-in models are becoming increasingly popular. What is the reason for the high demand for this technique?

1 Design and advantages of built-in hoods

All the advantages that are characteristic of built-in hoods from Bosch, Elica, or others, lie in their design. The housing of electrical appliances, which hides the engine, pump and filter system, is completely hidden during installation in a wall cabinet above the stove. Thus, it is possible to achieve the following positive points:

  • Minimal impact on interior design- reviews left on the network indicate that the built-in appliances look elegant and restrained, do not spoil the overall style of the space and harmoniously complement the kitchen interior;
  • Space saving– Built-in models like Hansa's OTS 625 are ideal for small kitchen. The body of equipment occupies only a part kitchen set, leaving you space in the locker to store spices, dishes or other utensils.
  • Easy Care– the built-in hood is installed in such a way that only the absorbing filter and the control panel remain outside, which greatly facilitates the maintenance and cleaning of the equipment.
  • Variety of choices– Bosch, Cata, Elica and Hansa fully built-in hoods are now produced in different styles and colors, which allows you to purchase the product of the desired modification.

The design of built-in models, as a rule, cannot do without a sliding panel, as in the popular OTS 625 model from the Hansa brand. Such a system makes it possible to increase the air intake area with a modest size of the product itself. Only fully built-in appliances are completely invisible, their panel is completely hidden in the cabinet.

At correct selection fully built-in hoods are very convenient in everyday life. We offer to understand all the intricacies of the purchase of such equipment.

2 Main technical parameters of built-in hoods

In the process of choosing optimal model, you need to carefully study the technical specifications of the electrical appliance and reviews. The first thing to remember is that the Elica, Bosch, Hansa or any other built-in hood should be located directly above the hob. Moreover, the dimensions of the appliance must completely coincide with the area of ​​\u200b\u200bthe stove, only in this way it will be possible to achieve maximum efficiency in eliminating odors and soot.

At the second stage of selection, it is necessary to calculate how much power a fully built-in hood should have. To determine the value of this parameter, you need to multiply the area of ​​\u200b\u200bthe kitchen by the height of the ceilings. The resulting number must be increased by 10 times - this will be the required power of the appliance. User feedback indicates that the presented formula works perfectly!

Modern fully built-in hoods are able to work almost silently. So that when you turn on the equipment, your kitchen does not shudder from the powerful roar or hum of the electric motor, pay attention to the noise level characteristic of the model you like. The best hoods, such as the OTS 625 of the global manufacturer Hansa, have an average of 35-50 dB. This value does not create discomfort for others.

Hoods trademarks Bosch, Cata or Elica differ not only technical features and design, but also the type of management. Their built-in panel is push-button, touch or mechanical. Budget retractable models equipped mechanical system control, which is implemented through a special skid.

Stylish built-in hood

Some hoods, such as Hansa OTS 625, are equipped with a simple and clear keypad. For a high-tech kitchen, retractable models with touch controls are the best fit. This technique has a lot of modern "bells and whistles", which allows you to program the operation of the hood to the smallest detail.

Special attention should be paid to the built-in lighting, namely the number and type of bulbs. The more powerful the backlight, the better the illumination will be. work zone kitchens. Of all the types of lamps that are found in hoods, the most reliable, durable and economical - LED.

2.1 Types of built-in hoods for the kitchen

Well-known manufacturers Bosch, Cata and Elica supply the market with a very wide range of hoods, the main difference of which is the principle of operation. All equipment of this sample is classified into two broad categories:

  • Recirculation– hoods that belong to this group operate in complete isolation from external environment. They take polluted air from the kitchen, pass it through filters and return it to the room in a purified form.
  • Bypass- models of this sample absorb odors, soot and grease particles, leading them into the ventilation shaft.

Some hoods, like the Hansa OTS 625, are capable of operating in both extraction and recirculation modes. The choice depends on the method of installation of equipment and the capabilities of the kitchen.

The properties of exhaust equipment are largely determined by the quality of the filters with which it is equipped. Recycling models should produce effective cleaning air, so they are necessarily completed and, which absorbs odors. Drain hoods are not so demanding.

Manufacturers often deprive them of the system fine cleaning because the air is expelled from the outside. Filters must be replaced or washed as they get dirty, otherwise their absorption efficiency is reduced.

2.2 Mounting methods

Built-in hoods, depending on the interior and features of the kitchen, as well as on the wishes of its owner, can be installed in several ways. As the reviews on the network show, Bosch, Cata or other appliances are most often mounted directly above the stove in a wall cabinet, like the OTS 625 model from Hansa. However, in some cases, the appliance can be built into a special niche in the wall.

This method is not widely used, because it is laborious, requires careful planning of space and the availability of free space for future equipment.

Not so long ago, classic-style electrical appliances have an alternative - a hood built into the countertop. The effectiveness of this technique is obvious, it absorbs vapors even before they have time to mix with the air in the kitchen.

Built-in hood before installation

At first glance, it may seem that installing a built-in hood, such as the Hansa OTS 625, is not an easy task and requires the involvement of a specialist. But it's not! you can do it yourself, following the instructions for the technique. It is recommended to start the installation process by fixing the hood housing inside the cabinet.

Naturally, their sizes must match! The main nuance that should be taken into account is the provision of free play for the moving part. Remember that you must not fix the hood too close to the hob, otherwise the hood may fail under the influence of high temperatures. Optimal distance between two objects 65-75 cm.

At the end of the installation, connect the outlet of the hood to the ventilation shaft using a corrugated or smooth-walled sleeve. Reviews on the network confirm that the installation of the hood is within the power of every man.

When choosing a technique, give preference famous brands such as Bosch, Cata or Hansa. They make reliable electrical appliances decent quality. Before buying a hood, determine what size you need.

Traditionally, models are produced in the format of 50, 60 or 90 cm. Carefully study technical specifications products so you don't have to be disappointed in the future. Your budget will be the deciding factor.

We bring to your attention an overview of popular models, which will facilitate the decision:

  • Hansa OTS 625 is a telescopic built-in hood with two electric motors, which provides the highest performance. Hansa OTS 625 has 3 speeds. The product has an interesting discreet design.

The right choice of design and size

All kitchen hoods are divided according to the type of installation and design. There are wall, island, corner, and recessed hoods. Standard sizes kitchen hoods (width): 50 cm, 60 cm, 90 cm and 120 cm. An important rule when choosing a hood is that the width of the hood should not be less than the width cooker(hob surface).

All kitchen hoods work in two modes:






Exhaust mode - air passing through the grease filter is cleaned of fat and then completely removed from the kitchen into the ventilation duct. Recirculation mode - the air, passing through the grease filter, is cleaned of fat, passing through the carbon filter is cleaned of odor, and then returns to the kitchen again.



Extract mode is more effective as it completely removes the smell from the kitchen.

Exhaust mode removing polluted air provides inflow fresh air(which is especially important when using a gas stove)

Exhaust mode is less noisy than recirculation mode

The exhaust mode is more economical, since it does not require the installation and periodic replacement of carbon filters

Correct installation of the hood

For correct installation hoods you need to know:

The volume of the kitchen room (to determine the required hood power)

The width of the stove (hob), the width of the hood should not be less than the width of the stove surface.



For efficient removal dirt, the hood should be installed at a distance of 65-75 cm from the top of the stove (hob). The minimum safe distance from the stove is 65 cm. If the height of the hood above the stove (hob) exceeds 75 cm, there is no guarantee that the hood will operate at the declared power level. The description of each hood indicates required distance up to the surface.



For correct operation hoods in exhaust mode:

Need to know diameter and location air vent kitchens to select the required diameter, length and type of duct

The length and number of duct bends should be kept to a minimum. It is recommended to use a duct diameter of at least 150 mm and no more than three bends.

For correct operation of the hood in recirculation mode:

You need to install carbon filters

The air returned to the room should not meet obstacles (cabinets, shelves, etc.)

Correct calculation of extraction efficiency with a minimum noise level

The hood works effectively if it provides air change in the kitchen at least 10 times per hour at a noise level of no more than 55 decibels

The more powerful the motor, the more efficient it is at low speeds, resulting in greater noiselessness and reduced power consumption.

The formula for calculating the required exhaust power:

Hood power \u003d Kitchen area x Kitchen height x 10 air changes (per hour)

For example, for a kitchen of 10 sq. meters and a ceiling height of 3 meters requires an extractor hood with a capacity of 300 cubic meters per hour. For a kitchen of 20 sq. meters and a ceiling height of 3 meters, the exhaust power should be at least 600 cubic meters per hour.

Correct Application hoods


It is necessary to turn on the hood 1 minute before the start of cooking on the surface of the stove (cooking surface) in order to create an air flow that will pick up fumes and odors

When the hood is running, keep the door closed to prevent changes in air flow at low hood speeds in case of drafts

To remove residual odors after the end of cooking, it is recommended to leave the hood switched on for 5 minutes or use the switch-off function after a certain period of time

Usually enough for cooking low speeds that remove light odors and fumes. More high speeds needed when cooking strong odors and in pairs or when cooking several dishes at the same time.

Proper Care behind filters


Grease filters protect the motor from grease contained in the fumes sucked in by the hood. A grease filter that has collected a lot of grease reduces the efficiency of the hood and does not protect the hood motor from grease.

Metal cassette filters provide effective trapping of fatty particles. For effective work hoods must be washed by hand or in dishwasher every two months.

Odor-trapping carbon filters are installed in the hood only in recirculation mode. They cannot be washed and should be changed every 3 months of operation. A synthetic filter heavily saturated with grease may ignite during cooking.

The replacement/cleaning time for the filters is based on an average use of the hood for about 3 hours per day.

Proper care of your stainless steel case

It does not take much effort to care for the hood. It is enough to periodically wipe the case soft cloth, impregnated with neutral detergent, free of chlorine and acetone, which can damage the surface.

Choosing a kitchen hood is not the easiest thing to do. It is necessary to take into account many nuances and details. Now available for sale different kinds kitchen hoods. They differ in many ways, from appearance to performance. To understand what is worth stopping at, you need to find out what this or that characteristic of the device means.

Why is it important to clean the air in the kitchen?

Many housewives, especially the old school, often ask this question. They simply do not see the need and advantages in the hood over the stove, they believe that simple ventilation is enough. However, this is not quite true.

During cooking, the air from the hot plate is released great amount substances that are not always beneficial to the body. It can be small particles food, steam, combustion products, soot (if something is burnt), volatile substances and even mold spores. All this is in the air of the kitchen, settles on the walls, is transferred to other rooms. As a result, substances accumulate in the kitchen itself (which is why in rooms with poor ventilation, a characteristic bad smell), and in the body of the hostess. Often the cause of ill health, fatigue and even various allergic reactions are just food particles.


When ventilating through the window, most volatile substances weathered, but a significant part still remains in the kitchen. The hood works much more efficiently because it captures air just above the stove. As a result, the particles do not have time to spread in the room, stay on the walls, etc., and this is its great advantage.

What types of extracts are there?

There are 2 main types of hoods:

  1. Flowing (or exhaust air).

While working, they use various methods air purification. In the first case, the hood is connected to the main duct or equipped with its own separate hood. Polluted air passes through a filter system and is expelled outside.

In the second case, after purification, the gas mixture enters the room back. This "walking in circles" is called recycling.


Types of filters for hoods

Exist different types built-in filters. First, they are:

  • disposable;
  • reusable.

They change as they get dirty. Most often they use coal as an absorbent. They have a plastic case, some porous material is attached to it, for example, synthetic winterizer. Charcoal filters are arranged according to the same principle. They need to be changed as they get dirty.


Reusable hood filters can be cleaned and returned to their place. They are made of steel or aluminum. A mesh material is attached to the body, which can be cleaned with a brush.

Filters are also divided according to the type of substances captured from the air into:

  • Oil-fat, i.e., trapping particles of soot, fat and oil. They are also called coarse filters.
  • Filters for odor elimination or fine cleaning.

Both types of filters are used in recirculation hoods. In flow - oil-fatty. Some manufacturers save money and do not always install cleaning systems in this type of hood. However, if the air is not cleaned, oily particles from the stove will eventually settle on the walls of the device, on the fan blades, and on other internal elements. It is extremely difficult to remove dirt from these places, especially if the hood is not disassembled. And in a very short time, the device may fail, cease to effectively purify the air, and even break down.


What type of control to choose?

It all depends on the personal preferences of the user, which control method seems more convenient, and that should stop. Various mechanisms are used in kitchen hoods:

  1. Push-button. That is, the choice of mode, the intensity of air circulation, on / off - all this is regulated by pressing the convex keys.
  2. Touch. In this case, the control panel is made flat, and the device reacts to touching the sensor.
  3. Slider. In this case, a mechanical switch is used.


Design features and appearance

There are many options for the location and external design of hoods. The following varieties are distinguished:

  • traditional (classical, suspended);
  • angular;
  • island (ceiling);
  • built-in (telescopic);
  • design.

Which option to choose - the buyer decides. However, each type of kitchen air purifier has its own characteristics that must be considered.


Traditional and corner appliances

The traditional hood has a familiar appearance to many. It is even sometimes called a classic. Such devices are installed kitchen cabinets directly above the stove. Most often they are used in recirculation mode. Disposable filters are installed in them, which are changed as needed. Some models may be equipped corrugated pipe for air extraction.

Corner hoods belong to the same type. They are simply designed to mount in a corner and have the appropriate shape.


Built-in and telescopic hoods

Built-in and telescopic devices are installed in the hanging box itself, which is located above the stove. Such hoods are almost invisible. Telescopic, unlike conventional built-in ones, are equipped with an additional panel that slides out when the device is turned on. Due to this, the area on which polluted air is captured increases. When the hood is off, the panel can be removed.

They cost not much more than conventional built-in units, but they work very efficiently, because they install multilayer filters, and at the same time take less space. They are often flowing.


Dome type appliances

Dome hoods got their name because of their appearance: a dome hangs over the stove, from which rectangular pipe, pulling air from the stove, reminiscent of a chimney by a fireplace. These devices are most often of the flow type, but can also operate in recirculation mode. At fireplace hoods, the dome resembles upper part fireplace.


Island hoods

Island (or ceiling) appliances are used if the stove is not against the wall, but in the center of the room. The hood in this case is attached to the ceiling and does not come into contact with other elements of the island-type kitchen. It is equipped with an additional air duct to connect to the main ventilation or window. Most often it can work in 2 modes: recirculation and flow.


Designer hoods

Designer products are called so because of the original appearance. As a rule, their design is developed together with common interior kitchens. Often made to order.


How to choose the size of the hood?

Of great importance is the size of the hood. It is necessary to choose it correctly. This parameter depends entirely on the size of the plate. The size of the catching surface cannot be less than that of the working surface. That is, if the plate is 60 cm wide, the hood must also be selected 60 cm or more, for example 90 cm. Otherwise, the air will not be cleaned properly. So, for 2-burner narrow hobs use kitchen hoods 50 cm wide, sometimes 60 cm. For standard plates the preferred option is 90 cm, and for wide ones - 120 cm.

For overall stoves, it is better to choose built-in or telescopic hoods. This will help make them less bulky, make the room lighter. It will also be possible to hide the air duct (which has an increased size for wide models) inside the drawer.

The height at which the hood will be installed will also be of great importance. Here you need to choose, focusing on your own comfort. The height of 65–75 cm is considered optimal, at least 60 cm. The hood will capture pollutants with high quality, but will not create a fire hazard. If the distance is less than 60 cm, then it will be inconvenient to work: you will have to constantly bend over to get to the stove. And if the oil-fat filter is dirty, the risk of fire increases significantly.


Power/Performance

Last technical specifications, on which you need to pay attention -. This parameter shows how efficiently the device works, how much air it can clean in a certain time. The most commonly used value is the cube. m/hour. To choose correct instrument, you need to know the size of the kitchen, its cubic capacity. A suitable hood will have time to drive all the air through itself 10-12 times in an hour. Formula for calculating the optimal device performance.
