Kitchen hood with ventilation outlet installation. Functional ventilation vent. How to choose ventilation ducts: simple arithmetic

The smell of food is good in the kitchen. In the cozy living room smells like flowers, perfumes, but not fried potatoes. Kitchen hoods can perfectly capture heat, steam and a kitchen dish or for free to burn electricity.

All kitchen hoods are divided into two categories: with connection to the ventilation shaft and autonomous. Properly selected and properly connected to the ventilation shaft hood will not disappoint the owners.

Types of kitchen hoods

The following types of cooker hoods are distinguished by installation:

• hinged (standard and flat) - attached under the shelf or hanging cupboard above the stove;
• built-in - built into the cabinet or specially constructed decorative box;
• wall - mounted directly on the wall, differ in the variety of design;
• corner - for installation in the corner of the kitchen;
• island - hung on the ceiling above the kitchen "island."

Functional ventilating extracts

Operating modes of the hoods:

1. Outflow. A kitchen hood with venting the entire volume of exhaust air. It connects to the ventilation shaft or draws air to the street through a special hole in the wall. Hot moist air and unwanted odors are removed from the apartment, providing a 100% effect.
2. Filtration. This hoods without connecting to ventilation. The air, filled with vapors and aromas of the kitchen, enters the filter and, purified, goes back. Filters are placed inside the case, they must be periodically changed or washed.

The filtration or recirculation mode greatly simplifies the installation. It is not necessary to decide how to extract the ventilation. At the same time, the equipment performance is noticeably reduced.

The filtration of the hood for the kitchen with the tap is made by sintepon, coal, paper, non-woven, acrylic or metal filters.

A dense charcoal filter reduces the power of the motor.

The rules for installing the hood without venting into the ventilation, and also how to properly connect the hood to the ventilation, read further.

Drawing capacity

According to sanitary requirements in the kitchen, it is necessary to provide 12-fold air exchange.

We use the formula:

P x V x 12 x 1.3

where P - the area of ​​the kitchen, 1,3 - equalizing coefficient, 12 - the frequency of air exchange, V - the height of the room.

Choose models with a power that exceeds the design by 10 - 15%.

Noise emission level

In modern dwellings, kitchens adjoin to bedrooms and living rooms, so the noise level is very important. A constantly buzzing hood will cause headache and fatigue.

The more powerful the hood, the more noisy it works. But responsible manufacturers (for example, BOCSH, Siemens, Samsung) manage due to the special form of blades, installation of pair fans and additional sound insulation to achieve rather quiet work at impressive performance.

For reference, noise levels in different rooms, in decibels:

• in a quiet room - 30;
• the whisper of a man is 35;
• the best hoods or quiet music - 40;
• human speech at a distance of 2.5 and a noise of an average quality of drawing - 50.

Do not purchase a hood with a sound level above 50 decibels. She will disturb the tenants of the apartment. The best hoods   produce noise of 44 decibels, and at maximum power not more than 70.

To minimize noise, models with an external motor have been developed. The engine is placed at the outlet of the duct. This is a kitchen hood connected to the ventilation.

Additional options

Lighting. This function is supplied with the vast majority of kitchen hoods connected to ventilation and autonomous. There are models with changing brightness of light, beam focusing. Sensor-equipped movements include light when the mistress approaches.

Touch screen control panel and display. Convenient, but you can do. The display shows the mode of operation, and the touch panel is much easier to keep clean than the protruding mechanical buttons or sliders (sliders).

Rules for installation of hoods

Installation and connection of the kitchen hood to ventilation requires knowledge of a number of rules:

• the body is hung only on the level, with careful observance of the horizontal;
• the distance between the electric hob and the hood should be 65 cm;
• the distance between the gas hob and the hood is not more than 75 cm;
• the bend of the duct for connecting the extractor to the ventilation does not exceed 90 degrees;
• when the length of the duct is more than 3 m, a second fan is installed to support the thrust;
• leaving the cooker hood in the ventilation, it is forbidden to block the ventilation vent in the wall;
• use pipes of the same cross-section, since at constriction aerodynamic noise is amplified;
• if cooker hood   is vented, it is advisable to install a valve to prevent back draft.

Before connecting the cooker hood to the ventilation, read the instructions to it.

Connecting the hood to the ventilation pipe

Before connecting the hood with ventilation, take care of all the necessary components. To connect the hood for the kitchen with a tap into the ventilation use corrugated or smooth round PVC ducts with bends. The second option is preferable, since it creates less resistance to air, a smooth inner surface is easier to clean. The diameter of the pipe is not less than 120 mm, it is selected on the output section of the hood. For fixing the air duct, the exhaust is equipped with an adapter.

The air duct should have no more than 3 knees, otherwise the efficiency of the work will decrease significantly.

Most often for the correct connection of the hood to the ventilation it is necessary to stretch the box and tighten the air duct end in the ventilation duct.

Connecting the cooker hood to the ventilation does not block the ventilation hole if you install a special grille.

The capacity of general ventilation is from 110 to 140 cubic meters of air per hour. The power of the hood can be 180 - 700 cubic meters per hour.

Before removing the hood to the ventilation, consider the possibility of venting the duct to a specially made hole in the wall. Otherwise, the working device can cause a "tipping" of the thrust. The phenomenon, especially dangerous in homes with gas heating devices, leading to carbon monoxide poisoning.

Air ducts are sealed, and the outlet is installed check valve   and a grid.

After the hood is vented, it is connected to the mains. Requires a standard voltage of 220 - 240 V and a frequency of 50 Hz. Sometimes an outlet is grounded to the outlet, eliminating the possibility of a short circuit.

The main task at installation of an extract without connection to ventilation - is competent to place and bring electricity.

An extract in the kitchen with a vent to the ventilation can effectively work when the filter area is equal to or slightly more than the hob.

According to the rules, the pilot start of the hood is carried out immediately after it is connected to the ventilation and power supply. And only after a successful first turn on put on a protective casing.

With the help of a hood with a tap to the ventilation you can eliminate unpleasant smells, soot, drops of fat. The latter, if not removed, remain on the kitchen furniture. Therefore, using the hood, you can reduce the need for regular repairs. Also in the kitchen there is a constant influx of fresh air, which positively affects the health of the household.

The principle of the hood for the kitchen

At the heart of the extract is the need to remove various contaminants and excess moisture, to clean the air. However, effective work is possible only with the presence of air ducts of large volume and good traction.

AT panel houses   with the latter may be a problem. To eliminate them, use powerful fans.

The visor collects the streams of stale air, sending them to the ventilation. Inside the hood, filters are placed, precipitating up to 95% of the contaminants. This helps to keep the atmosphere of the kitchen clean and healthy.

Types of cooker hoods to be connected to ventilation

There are several types of kitchen hoods. They differ in external data and functionality. Therefore, they should be chosen depending on the place in the room and the work that will be a priority.

There are three main types of hoods for the kitchen:

1. The dome.   The visor is like a dome that absorbs couples. This form is better than other "captures" evaporation, so it is used wherever high efficiency is required. Dome structures are fire, angular or insular. The latter are used in cases where the stove is located in the middle of the kitchen. They are suspended from the ceiling by means of cables or small pipes.
2. Inclined.   They look better than other hoods, and also occupy a minimum of space, so they are suitable for a small and stylish room. In order to better collect steam, in such models elements are provided that recline and create a dome or an umbrella.
3. Built-in.   They are installed in kitchen furniture, so they perfectly complement the design of the kitchen. The depth of these models is about 60 cm. But you can save 10 cm by buying a hood with a sliding visor. Suitable for all types and sizes of kitchens.

Study carefully exhaust system   before the purchase. Ask about the guarantee, which must be provided for at least three years.

How to choose ventilation ducts: simple arithmetic

Extraction of any design is obliged to change air at least ten times per day. For this reason, it is important that its capacity corresponds to the size of the kitchen. Calculations are made in advance using a special formula.

The formula looks like this: width x length x height of room = β (result) x 10.

The end result is the necessary performance of the device.

There is also a dependence on the material of the ventilation duct. When using a corrugated pipe, the formula changes slightly. Then from the resulting result (multiplying by 10 we leave), we subtract 40%.

Internal resistance has every turn. Therefore it is better to connect the hood with channels with a smooth inner surface. Try to avoid turning, and if you need it, do it at a right angle. Then the air will beat against the wall to a lesser extent.

How to choose a pull out elbow in the kitchen

Hoods having a vent to the ventilation are popular, because they are highly efficient. Their price is small, which is an additional pleasant bonus.

Assembling the duct must be done correctly. If you do not have experience in this area, it is better to contact specialists.

However, this design has some difficulties. Additional installation work. When installing it is important not to leave any slots, otherwise the hood will be weakly functioning. Corrugated pipe   looks not aesthetically and spoils the design of the kitchen. However, you can hide it with a stylish box or similar design tricks.

Functional features of the hood for the kitchen

Different hoods can have different sets of functionality. They, as well as the brand, significantly affect the price of the product. Therefore, decide what functions you need.

Especially popular are the following options:

• Presence of halogen lamps.   They are more reliable than standard incandescent lamps, and also illuminate the most convenient light for cooking.
• Multiple speeds.   The ability to switch them will be required at a different level of steam.
• Modern control panel.   It should be located on the front side of the case, so that you can control the device without detaching yourself from household chores. Electronic control allows the hood to operate in automatic mode.
• Touch Control Panels. They are particularly convenient, because they include the hood alone, when the sensors react to vapors or temperature changes.
• Case made of stainless polished steel. These are the most popular and expensive models, which are extremely durable.

There are glass cases. Their surfaces are difficult to wash, they almost always have a divorce. However, this is an excellent budget option.

Hoods consist of several filtration elements, each of which is aimed at removing a certain contamination. The plus of this design is that it can operate autonomously, without connecting to the ventilation units. The downside is that you need to periodically clean and replace faulty parts.

Solve all possible problems with a specialist in advance, in order to continue using the hood only with pleasure.

Choosing a hood for the kitchen with a vent to the ventilation (video)

Attention, only TODAY!

The advantages of the hoods with the circulation principle of operation are many, which is why they have gained wide popularity. Let's list some of their most important advantages:

• Most often they are mounted as quickly and without any problems. This is due to the fact that there is no need to install ventilation communications. However, there are some models, for example, pull-out hoods, built into the countertop, the installation of which, with an unprofessional approach, can cause some difficulties. For most other models, the installation process is extremely simple.
• Possibility of placing the cooker and hood in the place you need, regardless of the location of the ventilation shaft.
• Many models can work in two modes (both with tap and without). Having picked up such a model, you will be able to evaluate the circulating principle of work, and if it for some reason stops you arranging, you can connect the tap.
• Wide range of prices, ranging from budget options and ending with expensive, productive hoods for large rooms.

However, it should be noted that in comparison with the hoods that throw air into the ventilation shaft, circulation models have their drawbacks. If you take these two types of hoods in approximately the same price range, then more often the hood with a tap can cope with air cleaning better than without tapping. Thus, in order to achieve good results of air purification and at the same time to refuse to withdraw, it is necessary to pay extra.

In addition, the lack of a device with a circulation filtration method is also a strong dependence of the efficiency of work on the state of the filter. Therefore, choosing this model, you have to regularly monitor the state of the filter. Recall that in the presence of tapping, even a clogged filter will not significantly affect the operation of the hood, since air will be discharged to the mine or to the street. And in the absence of a withdrawal, the dirty filter will immediately affect the quality of air purification in the room.

Kitchen hoods are now found more often, because it is very convenient to use this technique, and its functionality is pleasantly surprised.

What kind of kitchen hoods should be purchased for the house, and what sorts of varieties are there.

Without stretching in the modern kitchen, nowhere

What is the main functionality of the hood with ventilation? Such a the technique helps to remove polluting pores from the kitchen, harmful substances released during cooking. All this dirty air is drawn into the hood and out of the house. The technique works with noise, but differs with high practicality and convenience.

Due to the use of such an extract, it is possible to make the air in the kitchen much cleaner, making it easier to find there. In addition, the equipment is turned on and off at the request of its owner, it consumes little electricity and almost always has a long service life.

Such a list of advantages can impress anyone, but the hood has its own significant drawbacks. What kind of flaws are we talking about?

1. For such a technique it is necessary to mount the duct system.
2. Often hoods at work are published loud and unpleasant sounds.
3. Before installation it is necessary to consult with a specialist, since ventilation system   may not be designed for such a voltage.
4. Often extraction at intensive work lowers the temperature of the house   winter and increases in summer, which creates considerable discomfort.

Another important drawback of hoods is that they need to be cleaned regularly. Dirt accumulates fairly quickly, and without regular cleaning, the technique will not function normally.

A huge selection of hoods will fit them into any interior

Of course, such a technique has significant drawbacks, but the list of advantages inspires confidence. Before taking on the installation of the hood, it is necessary to analyze the features of its functioning, drawing attention to the types of equipment.

Kinds

Types of hoods for home

Since the kitchen hoods are very popular, new species appear. and which ones are considered the most popular and convenient to use?

Dome

This hood is convenient because there are many options for its design. Also, the technique is characterized by decent power and considerable functionality.

  Among such models one can find even corner hoods, and therefore, the installation is easy to conduct in any room.

Flat

  Such a the model is convenient in the first place in that it does not require venting. Unlike the dome, they have a convenient and compact design. The technique works on electricity, but it has low performance. But if it is, ventilation may be needed.

Built-in

These types of hoods differ not only in their compactness, but also in attractive appearance. The hood itself is mounted directly under the ceiling, does not take up much space, but does not have a high capacity. It is unlikely that such a hood will be able to consume a large amount of harmful vapors in a room of even a medium size, but this is its version included in.

Restaurants and cafes continue to give preference to domed hoods, because they differ in enviable practicality and power.

Of course, mounting dome fans is difficult, but they have decent power and excellent performance. To ensure that the installation process does not take too much time, it is necessary to outline the basic principles of work.

Connection to ventilation

Install the hood is not difficult, the main thing is to connect correctly

The first thing to do when installing - is to prepare a surface for attaching the hood itself. To do this, holes are drilled for bolts, and anchors are laid in them. With the help of these holes it will be possible to attach the hood itself.

The process of connecting to ventilation by means of a duct has its own peculiarities. What kind of features are we talking about?

• Bending duct   and the corrugations should not be more than 90 degrees.
• If the duct length is more than three meters, you must connect another fan.
• In the derivation do not block the ventilation vent.
• When venting, it is better to install a valve, which will prevent back draft.

The distance between the electric cooker and the cooker hood should not be more than 65 centimeters. The distance between the hood and the gas stove should be at least 75 centimeters.

Ventilation is one of the critical requirements   safe kitchen

In order to carry out the withdrawal to the ventilation, it is necessary to stretch the box and secure it as tightly as possible its end. The installation of corrugation usually does not cause any problems, because it is convenient and easy to work with. The most important thing is that the air ducts are sealed, and the outlet on the grid is fitted with a non-return valve.

In order for the corrugation to function normally, it should have no more than three folds (knees). Otherwise, the technique will noticeably lose its effectiveness.

Often the kitchen hood is installed in the wall cabinet, so to say hides to increase the design appeal of the kitchen. The first thing to do with this installation is to secure the hood housing to the wallboard on the wall. Further in the cabinet it is necessary to cut openings for the lower frame of the hood. Cut these holes can jigsaw.

In the shelves, you also need to make holes for the air duct, and above it creates a hole for the cracker. Further, it remains only to stretch the corrugation through all the holes made and set the cabinet back on the wall.

The rest of the installation process is not complicated: the corrugation must be installed on the hood, secured with clamps. Then it should be taken to the ventilation, securely and secure there.

Now it is often not metal corrugation that is set, but PVC air ducts. They are more convenient and practical, besides, many specialists recognize their great aesthetic appeal.

How to install the hood in the kitchen:

Location of sockets and care

To extract the "cope" with their duties, provide her with proper care

Since the hoods consume a lot of electricity, you need to create a separate line for them, and otherwise the entire network can not stand.

The most important point, directly affecting the durability of the use of technology - is the right care for it.

How to clean the hood, see our video:

The whole process of care is that it is necessary to clean the outer surface of the hood, as well as wipe it with a cloth with a little detergent.

Unusual hood will be a decoration of the kitchen

With proper care of the equipment, it will work very long and as efficiently as possible. Such an extract helps to make the air in the kitchen clean, making it easier and cooking.

How not to remain without air?

So, let's take as an example an ordinary two-room apartment with a total area of ​​50 m2. This apartment has a metal door with a gasket and plastic windows. Also there are two ventilation channels - one for the bathroom, and the other for the kitchen and the kitchen ventilation duct is drawn. Now the hoods above the cooker are so powerful that at their maximum working position their capacity is 700 m3 / h and even more.

And now imagine that in such an airtight room the hostess decided to cook something and turned the hood over the stove to full capacity. The air volume in this apartment is only 130 m3. For drawing over a plate working at full capacity (700 m3 / h), it will take quite a bit of time to swallow, let through the air cubic meters of this apartment. As a result, it begins to pump air out of the apartment and creates a vacuum, and since the windows and the door are very tight and there is no air for circulation through them, there is only one place through which airflow into the apartment is possible - the ventilation opening of the bathroom. In such a situation, even the normally operating ventilation of the bathroom (toilet and bathroom) will begin to work in the opposite direction (return thrust). And, since ventilation is combined into a common system, then foreign smells from other floors start to enter the apartment, sometimes stinking to the point of indecency.

Extraction of kitchen extracts to ventilation

Each of us in the apartment has a kitchen. Everyone in the kitchen has a stove (gas or electric). And the overwhelming majority have a hood above the stove. Many people consider it the equivalent of ventilation of the kitchen. Otherwise, how to explain the fact that, installing the hood over the stove, the duct from it is fed into the ventilation hole of the kitchen, closing it completely? They do this for several reasons - either they advised the builders who made the repairs, or from complete certainty that even so the air from the kitchen is perfectly removed. Plus, the sellers say that the capacity should be selected taking into account the kitchen area.

In fact, all this is a delusion. Any building structures or communications are calculated for certain loads. Ventilation in this list is no exception. Our Russian ventilation ducts   Have sufficiently limited capacity for bandwidth. In the best conditions, their productivity is 150-180 m3 / h (for comparison, modern hoods have a capacity of 600-1100 m3 / h). The huge capacities of modern hoods are invented, of course, not for the Russian market. You, for sure, watched more than once American films in which the characters creep along the wide ventilation ducts, which, because of the huge section of the mine, the air intake capabilities far exceed the Russian ones. Unfortunately, for crawling around Russian ventilation, very small heroes will be needed.
