Kitchen is not only a place where you can eat deliciously or sit with a friend for a glass of "tea".This is also the place where we prepare our daily food, and this is mainly done by the hostess of the house. Every kitchen has a natural draft - this is laid down even at the stage of designing an apartment house. But any hostess will say that such a hood does not provide a full "cleaning" of the kitchen from steam, soot, burnt. That's why forced exhaust is essential to create comfort in the kitchen.
Manufacturers offer various models of such exhaust devices. The problem they have is cleaning the air in the kitchen, but the principle of work is different. Flat hoods do not need to be connected to a common ventilation system, since they are just cleaning the air and returning it back. In other words, they filter the air, freeing it from dirt, soot, smells. Conical hoods suck air from the kitchen and take it through the attached knee or integral pipe into the ventilation shaft of the house, and do not return it back to the room.
As a kind of such hoods, there are built-in hoods, a flat shell which is installed above the stove, and all the hoses are hidden in the cabinets. There are models that combine the first two functions - for this they have a special switch.
Let's consider an example of installation of an extract with an output of air in a ventilating channel of the house. First of all, the hood must be purchased, while making the right choice. You need to measure the dimensions of your kitchen stove, because the plates of different manufacturers and sizes are different. The hood should be at least as large as the plate, or better - if even slightly larger, otherwise all the soot and burnt will fall on the ceiling. It is necessary to get acquainted with the characteristics of the fan motor.
If the work in the kitchen is in the "normal" mode, then the fan of the hood itself is sufficient. And if something is intensively fried - soared, then the second fan is turned on at the same time. Such fans are freely sold in stores.
The location of its installation is best determined in the wall, in the opening of the ventilation duct of the house. The only difficulty, albeit small, is to put the wire there and put a separate switch in a convenient place. Then there will be no complaints from the wife that the hood bought a bad one, and "... than you thought, when you bought! !!You just need to get rid of! !! ".By the way, this is really an excellent option.
Next, determine the height of the hood installation. To be guided by two factors: the manufacturer's recommendation and the growth of the wife. It should be the most convenient to work at the cooker. It is not very pleasant if she, at her height, constantly touches her head. On the Internet, some authors still refer to the need to comply with the distance from electrical appliances to gas equipment. But this is a controversial issue. After all, all modern gas cookers have an electric ignition system. According to experts, the minimum installation height is 80 cm.
When buying a plate, it is necessary to immediately buy and "withdraw".At the hoods the outlet hole is of different shapes: round, square. And the dimensions can also be different. Therefore, it is better to immediately purchase a "kit": hood + elbow. It is necessary to look in advance at the hole in the ventilation duct of the house, to remove its dimensions. And more - you need to measure the distance from the plate to the wall where the ventilation shaft passes. In order not to find out at home that the length of the branch channel is not enough.
If the extractor hood is "round", then you can also bring it into the shaft. In the store you need to buy a cylinder with a non-return valve. Such a cylinder is placed at the inlet of the ventilation duct. When the fan runs, the valve opens and lets air in from the room, and when the hood is exhausted, it is closed. This protects the kitchen from drafts, dust and dirt. It should be borne in mind that the shorter the duct, the less it has bends, the better the traction.
