This item can be found in almost every kitchen. Installing the hood over the cooking place is no longer considered a downt of fashion. Thanks to the hood, combustion products, fat and other substances that can ruin the interior of the kitchen are removed. This problem is especially manifested when frying, when the vapors of vegetable oil heat up and rise up. If you do not use the hood, they will settle on the ceiling or walls. It is better to clean the hood several times than spoil the wallpaper or furniture.

Currently, there is a huge selection of various extracts of hoods, which makes it possible to choose the most relevant option, given the design of the kitchen. Installation of hoods in the kitchen is mainly carried out on their own. Such work requires elementary knowledge in public and electrical work. About how to install an hood in the kitchen with your own hands - further.
What are hoods
All kitchen hoods can be conditionally divided into several groups, depending on the shape, installation method and principle of action.
According to the principle of action, the hood can be divided into:
- Evacuating. The principle of operation of such a device is to withdraw polluted air outside the room, usually into a ventilation duct or hole in the wall. The evacuation of air masses occurs through the air duct, which is hermetically connected to the hood flange and the exhaust hole.
- Circulation. The work of these hoods is aimed at cleaning contaminated air with the subsequent dedication of it back into the room. Cleaning occurs due to the coal filter located inside the device. Unlike evacuating hoods, the operation of circulation requires a large electricity cost, as well as the constant replacement of the filter. The positive side of this type of hoods can be considered the absence of the need to install the duct and the evacuation hole in the absence of ventilation ducts.
By design, hoods are divided into:
- Lobed. The main unit acts as a lobed fan. Such hoods, despite their impressive dimensions, have low performance, but in comparison with turbocharged models they have a relatively low noise level.
- Turbocharged hoods. The main working element of such models is a turbine. Due to this design, these models have better performance, despite the relatively small sizes. The main drawback of these hoods is the noise level.
On the principle of installation:
- Dome hoods. Have large sizes and are installed separately.
- Built -in. They are installed inside the suspension cabinets above the stove. Typically, such models are mounted in small rooms to save space. Recently, telescopic extracts are very popular, the working surface of which increases with an active state.
Choosing hoods and ducts
The choice of hood and duct should depend on three factors:
- Design of the room.
- System performance.
- The width of the hob.
The hood, like the plate, is one of the central elements of the kitchen. That is why its shape and color scheme must correspond to the general idea of \u200b\u200bthe design of the room. If a white plate was bought, then the steel extract will not look quite aesthetically pleasing, and vice versa. With a small room, buying a huge cap either makes no sense, it is better to limit yourself to a small telescopic built -in hood, which will allow you to use the upper cabinet with benefit. Now large retailers are selling sets of hobs of ovens and hoods, which are made in one designer vein. By the way, in addition to a beautiful appearance, the sets are usually cheaper.
Experts advise the performance of the hood to select depending on the cubic of the room. Properly selected power of the device will become the key to normal and effective operation. The approximate effective power of the hood can be calculated by multiplying the room of the room by 10. That is, if the area of \u200b\u200bthe kitchen is 15 m 2, and the height of the ceiling is 3 m, then the power indicator for normal operation should be at least 15 x 3 x 10 \u003d 450 m 3/hour.
The width of the hoods is usually selected for dimensions of the hob. It can be more, but not less. That is, if the width of the plate is 60 cm, then the hood of 50 cm wide is not suitable.
The ducts for exhaust systems are made of plastic, galvanized or stainless steel, or from a corrugated pipe. The latter option is the most preferred due to a relatively low cost. The configuration of the duct depends on the shape of the hood flange. They are quadrangular or round.
When installing the duct, you need to remember one simple rule: the lower its length, and the smaller the bends on it, the more efficient the hood works. An ideal condition is to find the hood under the ventilation hole. If this is not so, you might think about the possibility of transferring the slab.
How to install an hood on a kitchen with a damper yourself
When installing the hood, the issue of violation of natural ventilation in the room is especially acute. To eliminate this problem, many experts advise installing an hood with a special valve - a “cracker”. It is a simple device for a thin sheet metal damper, which is installed in the ventilation channel pipe. Due to the weak spring, the “cracker” is in the closed position with the ventilation turned off. During the operation of the turbine, the air flow opens the valve, which allows you to remove contaminated air. This device will allow you to put the barrier to the Gary from the ventilation duct, which can return when you turn off the hood and poor traction in the channel. It also removes the problem of air from other apartments.
How to install a suspended hood in the kitchen in a closet
To do this work in the presence of a simple tool and minimal skills to work with it is quite simple.
Work order:
- The box in which the hood will be installed is removed from the wall. In the bottom of the box, a hole is placed under the installation of the hood.
- A hole is cut out using an electrician. To do this, in one of the angles of a drawn figure, a hole with a diameter of 10-12 mm is drilled so that the electric canvas can be made. Ideal accuracy is not required, still the seam will be hidden by the hood body.
- Then it is necessary to remove the shelves of the cabinet to cut a hole in them under the air duct. It is better to do this with a minimum tolerance in the larger direction, so that the duct freely passes into the hole without curvature.
- In the upper plane of the cabinet, a hole is cut out under the installation of a box with a flood. The allowance on each side of the hole should not exceed 3-5 mm. If you cut it more, you will have to use an additional volume of sealant, which will not look too aesthetically pleasing.
- Next, the corrugation is installed. It is carefully delayed in the holes in the shelf and is formed to approach the exhaust hole.
- Then a box with a cracker is installed, which joins the duct. The compound is sealed using silicone sealant, and the gap between the wall and the box of the cracker is blown by mounting foam.
- The last step is the installation of the hood itself. It is installed in a cut hole in the bottom of the suspension cabinet, and is attached using self -tapping screws into the mounting holes. Then the corrugation is worn on the graduation flanet and delayed with a clamp. It makes no sense to seal it, because in this case it will be difficult to serve it.
How to install an hood in the kitchen. Installation of electrical wiring
Even the simplest hood consumes almost 1 kW of electricity, which corresponds to a current of 4.5A. Therefore, the wiring should be quite strong so as not to cause the heating of the wires and its fire. This is especially important if the hood is mounted in the room where the repair has already been made. In this case, confidence is necessary that the wiring is able to withstand the load of an additional consumer. If there is no such confidence, then you will have to mount an additional line.
If the hood is planned to be installed during the repair process, it is advisable to provide a separate outlet next to it. It makes no sense to make the connection hidden in the wall, since in this case it will be difficult to remove the device for repairs. A separate line must be brought to this outlet. For this, a copper wire is best suited with a cross section of up to 2.5 mm 2. The wire of a larger section for this device does not make sense.
Before the outlet, it is necessary to install an automatic machine. This will cut off the power of the device in case of malfunctions. The machine must be selected depending on the size of the bandwidth. That is, if the wire with a cross section of 2.5 mm 2 It is able to withstand the load up to 20A, the machine is installed on the load 15A. In this case, when breaking the device, for example, when jaming the engine, the machine will turn off the power of the hood. Today, there are sockets with installed machines on sale, which are ideal for installing exhaust ventilation.
Exhaust care
Since couples in the preparation of products contain a lot of vegetable and animal fats, which, when solidified, are deposited on the surface of protective nets and other parts of the device, it must be periodically cleaned. When fats hit on electric parts and wires. Self -displacement may occur, therefore, with intensive use, cleaning must be carried out at least once a quarter. For this, special detergents are used.
In addition to the hood itself, it is necessary to clean the corrugation. This must be done carefully so as not to damage it, because its thickness is quite small.
