Cooker hood with ventilation outlet

The quality of air in the whole apartment depends on how well the kitchen hood functions. Fundamentally, two types of systems are distinguished: kitchen hoods with a vent to ventilation and recycling, chasing the air in a circle and performing its cleaning with filters. The latter type, due to its small effectiveness, will not be considered.

The need for installation

Any hood installed in the kitchen is obliged to drive out the air, identical to 10 volumes of the kitchen, in 1 hour. This is not a whim, but a strict requirement. sanitary standards. The kitchen is working intensively heating devices, using open fire, increased humidity. These factors lead to the concentration of carbon dioxide, vapors, harmful impurities. Open fire leads to a decrease in the level of oxygen in the room.When the circulation is closed in a circle, all the dirt accumulates on the exhaust grille. Therefore, the basic conclusion: poor-quality air must be removed outside, and replace it with fresh air.

The hood for the kitchen with an air duct is installed as close as possible to the cooking plate as the main source of pollution. The dome for the air intake is equipped with a special latticeon which clots of fat and dirt are concentrated. With this solution, the waste does not leak into the ventilation duct. For the hood in the kitchen with this design, it is important to ensure the flow of air, because its outflow is very large. When there is no influx - and this is important - there is rollover. This is the effect of pulling air out of the air duct itself back into the kitchen with a fairly flat atmosphere.

Any kitchen hood with a conclusion to the ventilation has two solutions: passive and active. In the first case, the outflow of polluted air is carried out under the action of its own thrust, in the second, this function is assumed by the fan.

Types of various hoods

According to various methods of installation of exhaust hoods with a vent to the ventilation are:

• Hoods island type. They are installed above the surface of the slab, and installation for ventilation is done on the ceiling. This significant construction is best masked under a stretch ceiling. This type has not been distributed due to time-consuming installation and high cost.
• Constructions mountedwhich are subdivided into dome, flat and sloping. Such devices easily fit into the interior of even a small kitchen, and the price is small. Depending on the location, they are angular and wall.
• Exhaust devices embedded. Their main superiority is expressed in compact size and good practicality. Separate types of such hoods structurally made retractable, which makes it possible to increase the area of ​​capture hood.

Which hood is better suited for real kitchen furniture - depends on the size of the cooking plate and wall cabinets.

Main advantages of vents with a vent to ventilation

The exhaust device with a vent to the ventilation ensures complete and high-quality air cleaning due to the exhaust air out of the room. If there is a need to maintain large-sized premises, the design is equipped with an additional motor. Undesirable factors include:

• labor-intensive installation;
• high noise level;
• professional installation of the duct;
• the need for fresh air.

Before the fan is installed one or two filter, which minimally purify the air, protecting the fan from pollution. The advantages of such flow devices should include:

• excellent level of performance, since the resistance to the air flow of the coarse filter is very small;
• availability in service (filters are easily cleaned or changed);
• 100% efficiency - all impurities are gone, no matter what size and quantity they are.

The whole system is turned on and off by the owners of the premises, it is not very energy-intensive, and its service life is quite high.

Considering that with modern apartment layouts, the kitchen is often adjacent to the bedroom or living room, the indicator noise level hood is an important quantity. There is a direct dependence of noise on the power of the motor, the more it is - the more noise the system.

The best manufacturers of hoods manage by using two low-speed motors, installing high-quality sound insulation and specialized fan blades to minimize the sound effect - this is practically noiseless hoods. It is better not to get a hood with a noise level above 50 decibels.

There is a way to drastically reduce the degree of noise: for this purpose, the motor is mounted on the external duct outlet.

There is another small drawback - you need to wash the filter often enough. rough cleaning. Dust on the filter is formed quickly enough, and without timely service, the system will not be able to realize its capabilities. But despite a number of shortcomings, the list of advantages is much more impressive.

Many consumers are wondering which hood is better? It is advisable to acquire the equipment of a firm with a well-established name in the market, for example, Crown - such devices work longer and more efficiently.

Choice of duct

Air ducts for exhaust are classified as follows:

• the shape of the channel cross section (sometimes square, rectangle or circle);
• performance material (metal or plastic);
• the configuration of the main trunk is either a rigid variant or flexible (corrugated pipes).

Experts recommend the use of round ducts - they have good aerodynamics. True, in small kitchens, they look very massive and take up a lot of space. With a small kitchen size, it is desirable to select rectangular ducts. They are fixed on the ceiling, thanks to which they look more compact. It should be noted that when buying air ducts with a rectangular cross section, it is necessary to immediately acquire the necessary number of adapters from a rectangular section to a circular one. This purchase will significantly increase the installation costs of the device.

Round duct

For the manufacture of metal ducts used mainly galvanized sheet. Such metal channels are very long, but the air passes through them with excessive noise. The analogue of plastic is less noisy, but also more expensive.

An important rule is that it is necessary to minimize the number of bends in the air channel, their number should not be more than three: in each bend, the efficiency is lost by 10%.

In the difficult scheme of fastening the air duct to the ventilation system takes a clear advantage corrugated pipe from aluminum. Such a pipe can bend at any angle, as well as stretch and shrink. The main disadvantage of such ducts is a large resistance to air flow. But if the corrugated pipe is fully stretched, the folds that create resistance will disappear and the air flow without obstacles will pass through the pipe. The section of the duct on the path from the exhaust hood to ventilation should be the same diameter throughout. A decrease in this indicator leads to a drastic reduction in productivity, and hence a drop in the rate of outflow of dirty air.

Connecting a kitchen umbrella to ventilation

This operation is quite simple and does not require professional training. But there are a few details that need to be mastered by a home craftsman, for the first time, who installs a kitchen hood. Consider this process on the example of a corrugated duct.

1. It is necessary to choose the best mounting height hoods The lower the umbrella is located above the hob, the greater the return on its work. But too low a location leads to the deformation of the product and the possibility of its ignition.According to the standards, the mounting height for gas stoves is 80 cm, and for electric tiles - 70 cm.
2. It is necessary to firmly fix the mounting on the wall, even if the weight of the hood is not very large. The main thing is to accurately mark attachment points. Immediately after installing the fasteners, they put on a kitchen umbrella.

3. In the vent hole set a special adapter. There is an option with the installation of profiled ventilation grille, which has a special pipe for corrugated pipes. The main - the external size of the pipe should be equal to the internal diameter of the duct.
4. There is a large range of ventilation grilles with built-in check valve. It is necessary both for the barrier from harmful odors from the mine, and for the prohibition of reverse thrust. Most apartments have both supply and exhaust ventilation. The umbrella is mounted strictly to the exhaust port.

5. An exhaust hood with ventilation outlet can only be used in apartments where there are several air vents. If, on the contrary, the kitchen vent is the only one in the apartment, then the arrangement of the built-in ventilation will be a mistake, as the whole microclimate of the apartment will change for the worse.But if there is a vent in the bathroom or bathroom, then they will take over the function of air exchange when the kitchen hood is closed.
6. Using fasteners, install the air duct with one side to the ventilation shaft, and the other - to the exit from the kitchen umbrella. The easiest to decorate corrugation decorative panel from special plastic or a box from gypsum cardboard. This will improve the interior of the kitchen, and create sound insulation from the movement of air flow.

Connection to the air vent

The most popular coarse filter is perforated foil or metal mesh. Such simple filters do not require a change, they can be refreshed in warm water with a little soap added. Syntheon filters work until they wear out, then they are thrown away.

Choosing the best hood

It is necessary to think over all the little things before buying, so that the process of operating the hood does not turn into endless flour.

Device dimensions must comply with the overall dimensions of the hob, it is quite acceptable a slight excess. The work of units of small size will be ineffective and the air will not be cleaned.

From power rating depends on the efficiency of the flow of polluted air from the kitchen. According to rough estimates, household appliances can remove 150-600 cubic meters of air from a room in 1 hour. For example, for a kitchen of 8 square meters with a ceiling height of 3 meters, the volume of air required for pumping is 380 cubic meters. Buying a hood of such power, you can guarantee the cleanliness of the air in the kitchen.

Hood with touch control

Stainless steel is the most durable by material for the manufacture of a kitchen umbrella, but this material significantly increases the cost of the device. If the case is made of metal with enamel coating, the price of such devices is very reasonable, but very careful operation is required. The most stylish option is a case made of tempered glass, but there are some difficulties with care, washing leaves stains.

High-quality hood must be equipped with lighting: LED or halogen. In some advanced models there is an adjustment of illumination or beam focusing.

The hood is controlled using the control panel:

1. Button viewwhere all the knobs and the buttons themselves for ease of control are located on the same side of the case.
2. TouchpadEquipped with humidity and air temperature sensors, this makes it possible to switch to the desired mode of operation, if necessary. The most convenient and practical panel.

With the proper execution of all installation recommendations and the operation of the hood will work reliably and efficiently, which will create a healthy coziness and comfort in the kitchen.
