This item can be found almost every kitchen. Installing an exhaust over the cooking site is no longer considered a tribute to fashion. Thanks to the hood, combustion products, fat and other substances that can spoil the kitchen interior are removed. Especially this problem is manifested when frying, when the pairs of vegetable oil are heated and ride up. If you do not use the exhaust, they will fall on the ceiling or walls. It is better to clean the hood several times than to spoil wallpaper or furniture.
Content
Currently, there is a huge selection of various models of hoods, which makes it possible to choose the most relevant option, considering the design of the kitchen. Installation of hoods in the kitchen is mainly produced by their own. Such work requires elementary knowledge in general construction and electrical work. On how to set the hood in the kitchen with your own hands - hereinafter.
What are the exhausts
All kitchen hoods can be divided into several groups depending on the form, the method of installation and principle of operation.
On the principle of the performance of the drawing can be divided into:
- Evacuating. The principle of operation of such a device is to withdraw the contaminated air outside the room, as a rule, in the vent or hole in the wall. The evacuation of the air masses occurs through the aircraft, which is hermetically combined with the flange of the hood and the outlet.
- Circulating. The work of these extracts is aimed at cleaning the contaminated air with the subsequent returns to its back to the room. Cleaning occurs at the expense of a coal filter located inside the device. In contrast to the evacuating hoods, the operation of circulating requires high costs of electricity, as well as constant filter replacement. The positive side of this type of extracts can be considered the lack of the need to install the duct and the evacuation opening in the absence of ventilation channels.
According to the design of the hoods are divided into:
- Blade. The basic fan is performed as the main unit. Such hoods, despite their impressive sizes, have low performance, but in comparison with turbocharged models have a relatively low noise level.
- Turbated hoods. The main work element of such models is a turbine. Due to such a design, these models have better performance, despite relatively small sizes. The main disadvantage of these extracts is the noise level.
On the principle of installation:
- Dome hoods. Have large sizes and are installed separately.
- Built-in. Installed inside the suspended cabinets above the stove. Typically, such models are mounted in small-scale premises to save space. Recently, telescopic hoods are very popular, the working surface of which increases with an active condition.
Choosing an exhaust and air duct
The choice of exhaust and the air duct should depend on three factors:
- Design of the room.
- System performance.
- Width of the hob.
Hood, like a stove, is one of the central elements of the kitchen. That is why its shape and color decision must correspond to the overall idea of \u200b\u200bthe design of the room. If a white plate was bought, the steel extract will look at all aesthetic, and vice versa. With a small room, buy a huge cap either does not make sense, it is better to limit the small telescopic built-in hood, which will allow using the top cabinet. Now large retailers sell sets of cooking surfaces and hoods, which are made in one designer vein. By the way, in addition to the wonderful appearance, the kits are usually cheaper.
Performance of the drawing specialists advise to select depending on the cabbage of the room. Correctly selected power of the device will be the key to normal and efficient its work. An exemplary efficient power of the drawing can be calculated, multiplying the room cubage by 10. That is, if the area of \u200b\u200bthe kitchen is 15 m 2, and the ceiling height 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 hood is usually selected under the dimensions of the hob. It may be more, but no less. That is, if the width of the plate is 60 cm, then the hood of 50 cm width is not suitable.
Air ducts for exhaust systems are made of plastic, galvanized or stainless steel, or corrugated pipe. The last option is most preferable due to a relatively low cost. The duct configuration depends on the shape of the exhaust flange. They are quadrangular or round.
When installing the air duct it is necessary to remember one simple rule: the smaller it is the length, and the smaller the bends on it, the more efficient the extractor. The ideal condition is to find the drawing under the ventilation hole. If it is not, you can think about the possibility of transferring the plate.
How to set a hood on the kitchen with a damper yourself
When installing the extractor, the question of the violation of natural ventilation indoors is worthwhile. To eliminate this problem, many experts advise to install a hood with a special valve - a clapper. It is a given simple device with a thin sheet metal flap, which is installed in the ventilation channel nozzle. Due to the weak spring, the "clapper" when the ventilation is turned off is in a closed position. During the operation of the turbine, the air flow opens the valve, which allows removing polluted air. This device will allow you to put the barrier of Gary from the ventilation channel, which may return when the exhaust is turned off and the battery in the channel. It also removes the problem of air from other apartments.
How to set a suspended hood in the kitchen in a closet
To do this work in the presence of a simple tool and the minimum skills of working with it are quite simple.
Procedure for work:
- The box in which the exhaust will be installed is removed from the wall. In the bottom of the drawer placed a hole for the installation of an exhaust.
- A hole is cut with an electric bike. To do this, an opening of 10-12 mm in diameter of 10-12 mm is drilled in one of the angles of the drawn figure so that the electrolybiz can be started. There is no ideal accuracy at the same time, still the seam will be hidden the housing of the hood.
- Then you need to remove the shelves of the cabinet to cut the hole under the air duct. It is better to do this with a minimal admission to the biggest, so that the air duct is fluent in the hole without curvature.
- In the upper plane of the cabinet, the hole is cut on the installation of a box with a clapper. The battery on each side of the hole should not exceed 3-5 mm. If you cut it more, you will have to use an additional sealant, which will look not too aesthetic.
- Next is established by the corrugation. It is neatly tightened into the hole in the shelf and shape to approach the outlet.
- Then the box with a chapperboard to which the air duct joins. The compound is sealed with the help of silicone sealant, and the gap between the wall and the box of the flap is blown by mounting foam.
- The last step is the installation of the hood itself. It is installed in the cut hole in the bottom of the suspended cabinet, and is attached using self-tapping screws into the mounting holes. Then the exhaust flange dresses the corrugations and is delayed by a clamp. It makes sense to seal it, because in this case it will be difficult to serve it.
How to set an extract in the kitchen. Installation of electrical wiring
Even the simplest hood consumes almost 1 kW of electricity, which corresponds to the current in 4,5A. Therefore, the wiring should be quite strong so as not to cause the heating of the wire and its fire. This is especially important if the extractor 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, you will have to mount an additional line.
If the extract is planned to be installed during the repair process, it is advisable to provide a separate outlet next to it. The connection hidden in the wall makes no sense, since in this case it will be difficult to remove the device for repair. This rosette needs to be summarized. To do this, the copper wire is best suited to 2.5 mm. 2. Larger sections for this device there is no point.
Before the socket, you must install the machine. This will allow you to cut off the device in case of malfunctions. The machine must be chosen depending on the value of the wiring bandwidth. That is, if the wire is 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 the device breaks, for example, when jamming the engine, the machine will turn off the power supply. Today, there are rosettes with installed machines that are ideal for installing exhaust ventilation.
Care for hoods
Since the pairs in the preparation of products contain many vegetable and animal fats in themselves, which, when frozen, is deposited on the surface of protective grids and other parts of the device, it must be cleaned periodically. When feeding fats on electrical parts and wires. Self-ignition can 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 and corrugations. It is necessary to do it carefully, so as not to damage it, because its thickness is quite small.
