Extract is a full «inhabitant» of modern apartment. If you cook in a family often it is impossible to do without this device. You don't want, that for a year a just repaired cooker hood has lost its magnificence. The answer is obvious, so – it is necessary to take care of struggle against fat and a soot. It is possible to arrange, of course, after each cooking a general cleaning, but to buy an extract is better. How not to be mistaken, choosing this device – learn from our material.

Before you decide to buy something from home appliances, it is desirable to imagine in general at least how it works. An extract – not an exception. Fortunately, the device is simple so we do not loose much time.

The primary aim of an extract is to save a ceiling, furniture and home appliances on cooker hood from subsidence on them from a soot and fat. Air cleaning from the unpleasant smells often arising in the course of culinary sorcery – also is a business of all its life. Besides, the extract serves also for illumination of a cooker hood desktop. Certainly, modern extracts look attractively enough so they can and decorate the kitchen. So, the device is one, and it has a lot of pluses.

The design of a cooker hood extract is that: the case from metal or plastic, sometimes with wooden or glass inserts, the motor (sometimes two) and filters for clearing of arriving air.

Filters are important

Filters in modern extracts are of two types: fat catching and coal. Fat catching filter can be made of synthetic materials and then it needs to be changed on a measure of pollution. The other variant – the filter from aluminum – it will work till the end of extract life. Certainly, you have to take care of it. In many extracts the special indicator of pollution of the filter is provided. If it isn't present – please don’t be lazy to check the filter by yourself, not less often than once in three months. Usually it is possible to wash aluminum filters in the dishwasher, or use warm water with a no aggressive washing-up liquid.

The coal filter struggles with cooker hood smells. Besides, it is necessary for clearing of air from a small dirt and a dust. It is necessary to change such a filter. The coal filter isn't included into the complete set of delivery of an extract, as a rule. To use it is possible in a case when the extract works in a mode of recirculation of air.

Extract operating modes

The modern extract can support two operating modes. If air passes through filters, it is cleaned and comes back in a room in a premise – the recirculation mode is active. Other variant – air tap: after cleaning, (that there were no pollution of an air line and internal mechanisms of an extract) it that is called, «goes broke» – in house ventilating mine. However, it is possible to organize all so that «bad» air will appear at once outside of a building – for this purpose it is necessary to do an aperture in a wall and to bring to it from an extract an air line.

Productivity of an extract

Cooker hoods are different: big, small, average. Quality of work of an extract directly depends on the size of a premise where it is established. If to use an unproductive (low-power) extract in a big kitchen is will be waste of money and nerves. Normally it won't clear air. Therefore before extract purchase always it is necessary to calculate – the device, for what productivity to you it is necessary.

What is the productivity of an extract? All is simply: it is a quantity of cubic meter of air which it «processes» at an hour. It is known that the qualitative extract should consult not less than with 10 volumes of сooker hood for 60 minutes. If the area of your cooker hood of 15 meters, and height of ceilings of 3 meters, means, its volume is equal 45 m³. It turns out that the extract should consult not less than about 450 m³ air at an hour. It is desirable to provide, however, some stock on this indicator. The matter is that at use of a mode of tap and the extract connection to the general ventilation the productivity of the device will inevitably decrease for the clear reasons – because of resistance of air. And bends of an air line don't add capacity. Don't forget also about not cleaned for a long time filter (sometimes it is so lazy….). It is thought that in this case, at the designated volume of cooker hood, it is necessary to look narrowly at extracts productivity about 800 m³ air at an o'clock.

Adjusting subtleties

Remember - air receiver of an extracts should close all working surface of a cooker! Only so it will be provided almost full cleaning of polluted air or its removal from cooker hood, Of course, even in this case it will not be possible to avoid the minimum losses, but they won't render appreciable influence on an overall picture. In an ideal the extract in general should be wider than a plate. However, when you measure the width of a plate, don't forget about the sizes of a niche in which you are going to hang up an extract. After all if its width of 60 sm , then an extract in width of 90 sm you can’t contain anywhere. Remember that extract installation should be made so that the height of an arrangement of an extract should be for gas cookers of 80 sm, for electric – not less than 65 sm.

Management of «flights»

The extract, of course, not the spaceship – open spaces of the Universe doesn't plow, but also it is possible and it is necessary to operate its work. Nowadays there are some control systems of extracts. The most modern, characteristic, as a rule, for really expensive models – a touch. The user simply touches this or that symbol on the control panel, thereby, activating the necessary function or a mode. Other variant – electronic (push-button) system – working process is supervised by pressing the necessary buttons. Often in such models there is a display on which the information on an extract condition is deduced. The slider’s system – is simple and convenient, provides ram-type switch of operating modes of the device. At last, keyboard system (it still name classical). In this case the necessary function is activated by pressing a corresponding key which doesn't come back in a starting position before repeated pressing or activation of other function, thereby as though confirming inclusion.

It is more than light, it is less than sound

Illumination – important parameter of cooker hood life. In darkness you will not prepare anything tasty. Of course, the cooker hood, all its working surfaces (a table where the food prepares, a cooker) should be well shined. It is possible, of course, to take care of individual illumination of each site of cooker hood, or to hang up one, but very bright fixture on a ceiling – all depends on imagination and possibilities. But there is also other variant – to use for illumination an extract.

Modern extract you will not name such the multipurpose device. As a matter of fact, it has two functions – clearing of air and illumination of surrounding space. About the last we’ll speak more detailed. Often extracts are equipped by luminescent or halogen fixtures of different capacity. In inexpensive models all can be limited to one lamp, and that is a bit more expensive, their quantity can reach three-four, and even five. There are models with possibility of focusing of illumination (for example, over a cooker) or its dispersion. It is possible to change intensity of a light stream. Some extracts, due to movement gages, start to shine more brightly when the user comes nearer.

Unlike light, a sound at extract work should be as less as possible. The device shouldn't rumble, as a plane AN-24 before launch. It is bad, if the noise made by an extract in an operating time, exceeds 60 Db. To understand we will explain- it is approximately corresponds to the noise level arising at usual informal conversation if to listen to it on distance of 1 m. Noise in 90 Db it is possible to compare to shout, and the lawn-mower rustles on all 100 Db.

Variety of kinds

Extracts are different: hinged, built in, «dominoes» and island. The models which design provides so-called «umbrella» concern the first, it is an air intake which should be over a cooker’s surface. This part of an extract can be direct or bent, metal or glass – depends on model and a design delicacy. The fixture of similar devices is carried out directly to a wall near to which there is a cooker.

Other kind of cooker hood air purifiers - built in. They, as a rule, are mounted in the hinged case intended for it over a cooker ,and they don't take a lot of place. Outside there is a panel of an air inlet, which in many models at work is pushed forward to capture as it is possible the big area over a cooker. In some built- in extracts the forward panel at an angle rises instead of being put forward upwards. Thus over a cooker something turns out like a dome. All for the sake of one purpose – not to allow to polluted air to rise to a ceiling. Classical built in devices have one conclusive plus – them it is not visible almost. So, such extract not only will make more pleasant your culinary experiences, but also won't prevent interior’s to experiment.

Dominoes

The dominoes are not only game in which pensioners play in a yard in summer time, but also a popular direction of development of built in home appliances. As a matter of fact, sets of cooker hood devices are divided into sections. One device – one section. Devices can be absolutely of different function – from electric or gas cookers to deep fryers, washing blocks (for fruit and vegetables) and, of course, extracts. Usually they are united by the general design. The sizes of blocks («dominoes bones») as a rule, standard – length of 50 sm, width – 30. All this cooker hood appliances (including an extract) are built in a table-top. Thus, the user has a possibility to collect cooker hood sets at own discretion. It can be, for example, two devices – an extract and the gas panel, and there can be a multipurpose complex. By the way, at desire of «bone» it is possible to change in places – conveniently. Extracts «dominoes» narrow directed actions – pass through themselves the air sated with culinary aromas, taking away it only from one ring (at plates «dominoes» usually more and don't happen). As a rule, they are capable to work in a recirculation mode.

Island extract

Island extract – the most expensive variant. Such devices are better for establishing, if you have the wide cooker hood and if there is a possibility to make cooker hood «island» – a separate working zone. It can settle down, for example, in the middle of kitchen or to be closer to one of walls –it depends on design of a premise and possibility of a supply of communications. Outwardly island extracts are similar with hinged (however, often manufacturers dare to experiment their exterior), but, as a rule, it is slightly more in the sizes. Besides, they fasten not to a wall as that nearby can not be, but to a ceiling, naturally, too over a plate.

Instead of an epilogue

As you can see – to understand what extract is more preferable to your cooker hood, is not too difficult. The main thing is to consider some key parameters. Having made it, you receive the excellent device if you don't want to have the smoked ceiling both fat cooker hood furniture and cooker hood appliances. Cost of extracts is various. There are economic models for 1,5-2 thousand roubles, and there are also devices with the built in radio receivers, TVs, with connection possibility to the computer, with use of expensive materials in furnish. Their price can reach and 50-70 thousand. A choice is for you.
