The most delicious dishes on the table with their preparation have not very appetizing smells. Vapor, soot, fumes, spray the fat from the pan, and let's be honest, even the good hostess and the milk can escape, and chops to burn. In the air creates high humidity, going fat droplets, particles of soot and even carcinogenic substances. And if you have a gas stove, these substances accumulate even more. All this, to put it mildly, not very beneficial to our health. So the kitchen must be equipped with an exhaust hood.
In city apartments kitchen space with ventilation holes, but passive hoods with their task coping ineffective. The kitchen should be equipped with forced air ventilation. Such devices are currently developed enough to satisfy both functional and aesthetic requirements of the consumers.
The principle of operation drawing
The principle of operation drawing-cleaner simple. It's like a vacuum cleaner draws air over the cooking stove (together with the steam, soot and odor). All this explosive mixture passes through a special filter. The process of recycling and the air returns to your kitchen already cleared.
Hood, based on exhaust ventilation with air duct (flexible corrugated tube, is connected with the nearest (often the only) vent in the kitchen. Naturally, pulling the air with soot and the smell is served directly in the ventilation shaft. Note that choosing this type of drawing you deprive your kitchen with natural ventilation. (If someone has smoked, or just Navona, you will need to keep clicking hoods).
Less effective are air purifiers. They are acceptable for use in homes where no ventilation at all or it is very weak.
Exhaust ventilation with a strong desire to bring out (without depriving themselves with ventilation holes). But this option isn't for everyone because of its complexity (and repair in the kitchen have to redo).
Design
Regardless of the model (recirculating venting or transformed), extractor fan always consists of:
housing
electro - mechanical group ventilation motor
- a certain number of filters
Case
The so-called external design, which includes controls, filters, control lamps and lighting system working surface. The housing is usually made of a metal plate of thickness from 0, 5 to 0, 8 mm (depending on type) made of natural or artificial stainless steel, copper or brass. On some models there is a glass or metal visor, which is turned by 45°, acts as a conveyor fumes in addition to its decorative function. Controls motor, variable speed, light switch located on the control panel, which is located on the front or on the bottom surface (depending on model and manufacturer). The strength of the system, the design, the location of the locking elements are designed to provide silent operation.
The width of the hood shall be determined in accordance with the dimensions of the working surface (plate).
There is a plate of 60 cm, 80 cm, 90 cm, respectively, have a hood, comparable with these modular sizes.
However, it should be noted that it is permissible to accommodate 80 - 90 cm hood over the hob 60 cm, but it is not recommended to do the opposite - to have a small hood over the cooker. In this case, of course, part of the fumes will spread around the kitchen, greatly reducing the efficiency of the hood.
Electro-mechanical parts
These parts, despite the fact that they are almost invisible to the user, and are harder to judge, are responsible for the durability, functionality and reliability of the entire system that it determines its value.
These parts belong to:
- conveyor or diffuser
- fan or turbine, or torque system
- motor
Performance
To extract coped with their tasks, the performance must correspond to the volume of the room. How to calculate volume of a room, know of any fifth grader. Performance should be specified in the passport, it is measured in cubic metres per hour. Health standards require twelve-change of air volume per hour. Therefore, the rated output will look like 12V, where V is the volume of the food. That is, if the area of your kitchen the 10 square meters and a ceiling height: 3 m, you will need the performance HH = 360 cubic meters/hour. It is better to buy a hood with a small margin, you will use it not at full capacity, and it will last longer.
When buying, remember that the size of the air intake should be slightly larger plate size.
Filters
Filters for air purifiers are disposable (paper, non-woven, polyester), they need to change, when to stop reading special label applied to the filter. Reusable filters (acrylic, aluminum) periodically, about once a month, clean and wash with detergent. This so-called lters. Coal filter filled with activated carbon should be replaced every 4-6 months.
A dirty filter reduces the performance of your air cleaner and increases the load on the motor that may lead to its failure.
Prices
The price range on the hood is so large that implement their choice and can fans of the show-off, and a young family with sharply limited budget. There is the most simple model for $ 20, there $1000, with features that may never be used. But, choosing the hood, is, probably, to look attentively at the price range from 150 to 400 dollars, because the cheapest models can be equipped, for example, by an electric motor without bearings, which next month will begin to rattle, and in two completely stop. Or decorative elements applied plastics that will warp from the heat plate.
In General, the hood is not the most difficult household appliance, so to say that the more expensive the better here is not necessary. Therefore, if the model is worth $200 you satisfied with the performance and design - safely buy, it will last you a long time.
