As a result of the ubiquitous use of plastic windows in the kitchens of our houses, natural ventilation was distinguished, which was provided with wood frames. Meanwhile, efficient ventilation in the kitchen is simply necessary. Moreover, it is necessary to organize it with the knowledge of the case so that instead of the hood of the kitchen air, do not get the influx of "aromas" from neighboring apartments or from the toilet.

Most domestic apartments are equipped with plates, in which natural gas is used. In the process of its combustion, carbon dioxide is formed, the poisonous properties of which are manifested as it increases its concentration in the air.

The most reasonable and modern solution to this problem is the installation of exhaust and forced ventilation of the room.

Modern hood - an indispensable kitchen attribute if a gas stove is present: it can be removed from the room unlawful and carbon dioxide

So, ventilation is necessary even in the case of the perfect operation of the gas stove. The need for it increases with errors in setting up equipment, which may cause carbon monoxide. It is much more dangerous carbon dioxide, and its presence can not be noticed: this gas has no color, no smell.

In addition, gas pipeline or natural gas can not burn completely, accumulating in the air. There are situations when the flame burner went out. For example, it was flooded with "escaped" milk. If there is no special protection, then the gas entering the room can provoke an explosion capable of shovel throughout the house.

It turns out that, starting to work with the gas stove, you need to immediately turn on the fan of the exhaust device. But the presence in the kitchen electric stove does not reduce the importance of ventilation of this room.

Food burning, which often happens in fans of fried potatoes and fish, is accompanied by the release of harmful compounds, which are formed as a result of pyrolysis of organic compounds. Those who prefer food prepared for a couple know that evaporation leads to an increase in the humidity in the room. And its level should also be reduced.

Even if your kitchen is equipped with an electrical cooking surface, the exhaust will be useful to you to lower the moisture content in the room and eliminate the smells of cooking

And even supporters of the smell of fresh baking understand that it is impossible to saturate this wonderful aroma. A mixture of attractive odors at first turns into the messenger of partially decomposed volatile organics, the presence of which in the air is unlikely to please someone.

Conclusion: Hood in modern cuisine - this is not a tribute to fashion, but a vital necessity.

Varieties of kitchen hoods

Different needs of users cause commodity producers to develop proposals that would be optimally suitable for requests for a particular buyer. Therefore, the range of exhaust devices for the kitchen, which offers us the modern market for household appliances, is quite wide. We will try to figure out their diversity.

By the method of cleaning the air masses

Cleaning air in the kitchen in different ways.

Depending on which one is applied in a particular model, the hoods are divided into:

  • Evacuating. These models output air from the kitchen outside the air ducts made in the form of a metal box or corrugated pipe. To make such a device, it is necessary to have a ventilation channel or a simple hole. Usually, the air duct is supplied with a valve that prevents the occurrence of reverse thrust.
  • Circulating. This model provides a carbon filter similar to a gas-shaped. In fact, this is not a hood, but the filtering unit, cleaning the air from the main "aromas": there is no air exchange with an external environment. Such a device attracts simplicity of its installation, but it cannot be protected, for example, from gas leakage.

Circulation hoods may adjacent to the standard ventilation of the kitchen. Their disadvantages usually include high cost and expensive maintenance: coal filters require periodic replacement.

The circulation model of the kitchen hood will not help you if the room accumulated carbonate or carbon black gas, and the evacuating easily cope with this problem

A feature of the evacuating extract is that it displays and excessive heat, which is always formed during the cooking period. There is no such function at the circulating model.

Design

In addition to the main function, buyers pay attention to other distinctive characteristics of various models. The exhaust device should fit well into the overall interior of the room, be convenient to operate and still: well, if used it was possible to save it and install it alone.

Therefore, modern hoods are distinguished not only by air purification, but also by the method of installation, design, manufacturing material and the presence of additional options.

The fireplace or dome extract is often found in our homes: it is important that the area of \u200b\u200bthe lower part of its dome corresponds to the area installed indoors

By the design of the design, exhaust devices are divided into:

  • Dome. This model received its name due to the form of the air intake. It looks like a truncated pyramid, the dome of which is located directly above the stove. From the hole in the upper part of the dome, the air liner is departed, transporting the air beyond the kitchen through the hole in the wall or through the ventilation channel.
  • Embedded. Such a hood is located inside the furniture in the kitchen. Quite often, the built-in hood is equipped with a retractable panel, which allows economically to spend the space space and, at the same time, to ensure comfortable control of equipment.

Before ordering furniture and buy a hood, you should plan the kitchen room so that furniture and household appliances should not interfere with each other, it would be aesthetic, and it would be comfortable to use them.

The spatial layout is very important and when the embedded exhaust device is. As a rule, if the hood is not included Initially, the furniture under it is placed on the order. At the same time, all nuances are necessarily provided, allowing all the elements of the embedded equipment to be beautifully and gently.

Classification at the place of installation

The exhaust equipment is installed in the kitchen, taking into account various factors: the size of the room, the location of the plate and so on.

Well, if in the room of your kitchen high ceilings, then the modest wall hood will look very impressive

At the place of installation, the hoods are divided into:

  • Wall. In this case, one side of the hood dome is adjacent directly to the wall, and the second is above the stove.
  • Corner. Placement plates in the corner not only saves the area of \u200b\u200bthe kitchen, but also makes the cooking surface more accessible. The design of the dome of the corner hood has a form at which the two sides fit into the angle of the room, lightening tightly to the walls.
  • Island. Lucky, which have a large kitchen room, can afford the installation of an island design. It is placed above the stove located in the center of the room.

In the range of manufactured models there are varied options for hoods. For example, flat models are mounted under furniture so to hang over the stove.

What to say about kitchens, the area of \u200b\u200bwhich allows you to place the stove and the desktop right in the middle of the room, and the exhaust - above the island slab

Before you independently install the hood in the kitchen, you must carefully examine the instructions. For each of the models there are own nuances of mounting, but some common rules apply to all hoods. This is the height on which they should be located relative to the surface of the slab. For gas plates, the distance is from 75 cm, and for electrical - no less than 65 cm.

Mounting rules are not so much, but they need to strictly follow, because they are dictated by concern about the security of the owners of the house

So, the lower installation level is defined, the upper one is selected independently. And it depends on the growth of apartment owners: use the stove and hood should be convenient.

Most often, modern buyers prefer embedded models. They are cheaper, and they are enough just to mount them.

Concept for kitchen drawing device

The composition of any hood includes the following elements:

  • Fan with electric motor. A multi-speed asynchronous engine ensures the rotation of the exhaust fan, due to which the air flows pass through the filters delaying fat.
  • Filters. All hoods are equipped with grease filters of reusable or disposable. Coal filters are present only in circulation models and act similarly to activated corner. Their replacement is performed once in 3-4 months of operation.
  • Lighting lamps. The lighting of the cooking surface is performed using incandescent lamps, LED or halogen lighting.
  • Speed \u200b\u200bswitching circuit. In different models, switching the speed is carried out in various ways: with the help of sensory devices, by means of buttons or using the slider switch.

Take a look at the standard exhaust power grid, in which all the elements named above are present.

The standard electrical hood for kitchen includes all the basic elements listed by us above and presented the order of their connection.

Safety design

The exhaust equipment kit necessarily enters the fan, which means that the extract must be connected to the outlet. If you just started repair in a new apartment, be sure to provide a separate outlet for exhaust, because this equipment must constantly be in the connected state.

Employment Sockets The only device allows you to hide it for elements of the furniture headset. But do not forget to provide easy access to it. There is another important rule: the socket should be located not closer to 60 cm from the sink of washing and from the stove. Remember that this exhaust is an electrical appliance that is able to hit the current, so the electrical safety issues should be treated seriously.

The kitchen, like the bathroom, is a room in which it can be hot and wet. Excess moisture and fat from cooking settles on the hood grill. This creates favorable conditions for an electric breakdown on a metal casing from a fan motor. For this reason, the instrument should be connected to the electrical network using three wires.

The connection diagram of the fan included in the kitchen hood is clearly demonstrates that three wires are needed: phase, zero and "earth"

In the composition of the wiring should be zero, phase and "earth". Grounding wire is easy to distinguish with yellow isolation and along the longitudinal green strip. Modern houses are equipped in advance with euro seals and grounding circuit. In this case, a sufficiently ground wire is connected to the corresponding plug terminal. It is easy to distinguish from others on the icon in the form of three multiple parallel lines.

The older buildings may not have grounding circuits. In this case, it is necessary to take care of the protection yourself. In the event of a breakdown on the housing, the ground will allow the protective machine to disconnect. In addition, it is necessary for equalization of potentials. As an additional protection, it is recommended to make the hood outlet to make a separate cable with the protection of the UZO and the switch-machine.

How to independently make a protective grounding

To build a protective ground in the old house, it is absolutely not necessary to dig a trench and drive into the ground metal pins. It is impossible to ground exhaust equipment on the water supply, heat center and, moreover, the gas pipe. It is dangerous not only for you, but also for neighbors.

For the grounding device in the house of the old building, it is necessary to find a deaf neutral and connect to it. To do this, open the introductory shield in your stairwell or in the apartment. The wires included in it are enclosed in a pipe that is closed in the wall. It should be a threaded pin, perhaps with previously connected grounding. This is the desired deaf neutral: the pipe is reliably grounded.

You need to take a flexible stranded wire, the cross section is at least 2.5 mm 2, and to spend it from neutral to the installation location. The hood should be connected to the network using a 6.3 amp automatic disconnector.

The outlet is hidden behind the elements of built-in furniture, but access to it is very easy to get: just open the door you want

As already mentioned above, other groundings can be on the deaf neutral. It is impossible to disable them. Its terminal should be thrown over already available and consolidate it with the help of the nut. With a smooth surface of neutrals, a clamp can be used to fix the ground. Excellent if the electrician of your management company is in fulfilling this work.

Pay attention to the problem of ventilation

When installing the drawing, a regular ventilation system of the apartment can be broken. An attempt to solve this problem is punching specifically for extracting the extra opening outside or in the ventilation channel. But the desired effect is not achieved. The cross-sectional area of \u200b\u200bthe same ventilation channel does not increase when another hole appears in it.

With a successful coincidence, only ¾ Chad from the kitchen will go to the channel, and ¼ will remain in the apartment. If the outside will be a strong wind or thrust from the lower floors, then all Gar will return to the kitchen or go to the neighbors, which can turn into spoiled relationships with them.

As for the withdrawal of the air outward through the breakdown in the wall, the supporting structure is affected. Such work must be pre-coordinated, to draw up draft changes. In addition, such a solution creates the danger of condensate settlement in both the air duct and the fan motor. Then the breakdown on the body is almost inevitable.

The principle of its functioning is well disclosed on the work of the hood with a clapper, the principle of its operation: air masses will not flow through the duct back to the kitchen room

As an exit of the situation, it is proposed to use an additional section of the aircraft, equipped with a flapper valve. The diagram of this device is shown below.

Under the air duct is a window in the form of a square, the side of which is ¾ of the diameter of the air duct. This allows the area of \u200b\u200bits cross section to fit the similar area of \u200b\u200bthe air duct. The perimeter will be slightly smaller than the duct circle length. Then it will not arise with the connection of complexity.

The damper can be made from aluminum 0.5 mm thick or from the same in the thickness of fluoroplast or fiberglass. It is preferable to the product from aluminum, because not only the rigidity and thickness of the material is important, but also its ease. The triggering of the flap will be more efficient with a smaller specific weight of the material from which it was done.

The flap is equipped with a weak thin spring. Its function is as follows: when the flap will be raised into the upper position and the impact on it will stop, it should quickly return to its place. If the spring is weakly stretched, but tough, then for our goal it does not fit. The surface component of the spring should have 0.2-0.3 mm in diameter. With a length of 120-150 mm, the diameter of the spring itself should be 3-5 mm.

Using neutralizers smell

Often kitchen exhaust devices are supplied with smell neutralizers. In our stores you can find three types of neutralizers.

  • Chemical. These neutralizers must often be changed, because they are quickly tightened with fatty film and cease to act, without working out their own resource. In addition, they themselves exude compounds that are harmful to health.
  • Electrionization. If you have an ionizer, the principle of operation of this device is also familiar to you. But in any room of the house, harmful substances are in a significantly lower concentration than in the kitchen over the cooking surface. To neutralize them, a strong discharge is needed, which can harm and the hostess standing at the stove.
  • Ultraviolet. When using neutralizers of this type, it is necessary to sometimes clean the light bulbs and change them about once every two years. And these light bulbs are not suiced. But such a neutralizer is safe for people's health. Moreover, the lamps emit not only ultraviolet, and also light: white or with a small blue.

Armed with the information received, we will choose the desired neutralizer not blindly, but with the knowledge of the case.

A few words about ducts

The air duct is not included. It will have to be bought separately. It is believed that the metal box with a rectangular cross section looks aesthetic aluminum corrugation, but he also has its advantages.

The one who believes that corrugation looks not too attractive, maybe mistaken: under certain conditions it is able to even decorate the interior of the room

Corrugation should be selected with such a diameter that corresponds to the inlet at the top of the hood cap. If the length of this pipe is less than 1.5 meters, the aerodynamic resistance of this material is practically negligible in comparison with random losses arising from ventilation in ventilation. Corrugation is easy to cut by conventional scissors.

Corrugation can be given a square shape to connect it with a clapper. She completely lacks resonant properties, sometimes emerging hard boxes. If you still prefer to purchase corrugations, then cooking food in your home will never accompany the monotonous hum.
