Sizes of hoods for the kitchen: norms and requirements

The dimensions of the hood for the kitchen depend on the dimensions of the room, stove, for built-in models - also on the size of the furniture. Therefore, the device is usually purchased after the stove, and their location is planned and taken into account even during the repair.

Dimensions (edit)

There are a lot of models of hoods on sale with different sizes, capacities and designs. The main types are flow and recirculation. They differ in the principle of operation: the first take air out of the kitchen into the mine, the second filter it and return it back to the room. Many modern devices connected to the ventilation shaft can operate in both modes. To do this, you need to install another filter in them - a charcoal one, to absorb odors.

According to the method of installation, there are suspended models on the wall, domed on the ceiling and recessed. The latter are often made retractable in order to increase the air intake surface.

In addition to the dimensions of the device itself, the configuration of the ventilation pipes for the hood is taken into account. If the diameter of the air duct does not correspond to the outlet of the device and the inlet to the shaft, the performance of the device decreases and the noise level increases.

Small

For a room in which every centimeter counts, compact devices are suitable: telescopic (with a pull-out panel) and built-in (the narrowest of all). Both types can be mounted in a wall cabinet, which additionally serves as a storage space.

Small kitchen hoods are used on a 2-burner hob. In this case, the dimensions of the hood are 30, 40, 45 cm wide. If a family of 2 people rarely cooks food on the stove, and the size of the kitchen is small, it makes no sense to install a large-sized exhaust device.

The most common, 60 cm

Range hoods 50 - 60 cm are medium. They are also the most common, since the 4-burner stove has the same dimensions. The standard parameters of the hood are 55 - 60 cm, corresponding to the most purchased models. They are installed in a kitchen with an area of ​​9 sq.

These devices do not look bulky, neat, easy to install and easy to purchase at an affordable price.

Large

There are also larger hoods. They are needed in the kitchen combined with the living room, dining room, in professional kitchens. They are installed above the island or against the working wall. Most often, suspended and domed ones are used. Such devices take up the most free space, but on large areas they look presentable and solid.

Household appliances resemble a trapezoid, oval, rectangle in shape. The dimensions of the hood for a large kitchen range from 70 to 120 cm.

Standards and requirements for a cooker hood

The dimensions of the hoods are not as important as the performance. The power of the device depends on the volume of the room. According to the norms, in order to calculate sufficient performance, you need to multiply the volume of the kitchen by 10, or better by 12. If you plan to install the device higher than usual, you need to take a model with a higher performance. Below is a table for calculating the power of the hood, based on the parameters of the room:

The height of the device above the stove also plays a huge role. A distance of 65 cm above the electric stove and 75 cm above the gas one is considered safe. For inclined models over 55 cm.

With a gas stove installed in the kitchen, a recirculating hood is not suitable, since it does not rid the air of carbon monoxide.

The dimensions of the built-in hood correspond to the upper cabinet, which is located above the stove. To ensure that the suction area is sufficient and at the same time does not bang your head against the device, telescopic models are chosen, that is, with a pull-out panel.

Device depth

Usually the width of the cooker hoods is the same as the depth of the appliance. This is due to the fact that the cooking surfaces of the stove are made predominantly square in shape. If the kitchen is narrow and there is a desire to reduce the depth of the hood, a pull-out model will be an alternative. When folded, the cooker hood takes up half the depth, if necessary, due to the pull-out panel, it reaches 60 cm. An inclined hood can also save space.

Exhaust height

The device itself has a height of about 120 cm. This applies to supply and exhaust models in which there is a large engine inside. Recirculating hoods have a minimum height of a few cm, which makes them easy to fit into any kitchen. With a shortage of space, you can choose such a solution to the problem. However, in terms of power, it is significantly inferior to flow-through systems and requires periodic maintenance - changing the filter.

The control panel should be just above eye level to make it easy to use.

Compliance with the dimensions of electric stoves and hoods

Wrong if the working surface of the hood is smaller than the cooking surface of the stove. It will not be able to qualitatively clean the air from steam, fat, and other small particles. All this will fall on the nearest surfaces and settle on them. Therefore, a one-time savings can lead to high costs later on repairs.

With large areas of the room, frequent cooking, you can install an extractor hood that is larger than the stove. It is important to understand that in addition to the dimensions, you need to take into account the power of the device, there is no direct relationship between them.

The dimensions of the built-in hoods must definitely correspond to the dimensions of the cabinet. It is easier to do this if the equipment is bought before the headset, or the furniture is made to order.

Installation safety

The distance to the slab is not taken into account in vain. With a closer than it should be, the location, there is a risk of fire of the device, melting of materials.

You also need to well attach the hood itself to the wall. Taking into account the weight of the product, reliable fasteners are selected. Hanging models are mounted to the wall, domed models to the ceiling, built-in hoods inside the cabinet. In the latter case, it is important to firmly fix the cabinet to the wall. The air duct is fixed in several places, every 1 or 1.5 meters.

In order for the unit to efficiently clean the air, the chimney must be properly installed. Its diameter should be no less than the hole in the shaft of the house. When choosing the path of the pipe, you need to make as few turns as possible; angles less than 90 degrees are unacceptable.

The size of the air duct for the kitchen hood is 3 - 30 cm in diameter, it is selected for a specific model of the device. On a standard kitchen area of ​​8-10 m2, pipe diameters from 18 to 24 cm are most often used. For rectangular ducts, the dimensions are 55 - 60 cm by 110 - 205 cm.

Models

The choice of device is determined by:

• Mode of operation. Exhaust models take up more space, but better cope with the task of air purification. Recirculating units are compact, they make more noise. They are installed only when it is impossible to fit a flow-through device into the interior. The dimensions of the hood for a kitchen with a vent into the ventilation are usually larger than without a vent.
• The performance of the device is determined by the volume of air that passes through it and is cleaned per unit of time. You don't need to use a powerful model if you rarely cook. The norm is such a performance that allows you to completely change the air in the kitchen in 1 hour.
• By the type of attachment and location: corner hood, island, hanging, fireplace (they are also dome).
• Depending on the control method - touch, push-button. Many come with a remote control.
• The standard design of the device is stainless steel, suitable for different kitchen styles. Extracts from glass with a tinted effect look more original. You can buy products painted in a suitable color. The most common are black, white, gray, you can choose beige, brown, silver models.

The choice of the location for the hood is influenced by the location of the stove and the outlet to the ventilation duct.

More and more buyers prefer inclined, or visor models. They look elegant, modern, create less noise during operation, and are energy efficient. Regulation of the device is simple and convenient, it includes ample opportunities: delayed start, choice of operating mode, duration, automatic shutdown after a specified time. Many, due to the built-in odor sensors, turn on automatically, without requiring human participation. There is an option to determine the state of the filter, which helps to keep the device clean and working.

Another function that is firmly entrenched in kitchen hoods is the illumination of the hob, since almost all appliances are equipped with lamps. When buying, you need to pay attention to which lamps are built into the panel. Incandescent lamps get very hot on their own and heat the surface of the device. It is better to give preference to LED lamps.

Recirculation devices purify the air by passing through grease and charcoal filters. The fatty one is periodically cleaned with the help of detergents, the charcoal is replaced with a new one. The device is fixed to the bottom of the cabinet or to the wall.

Pull-out models are an excellent choice when the kitchen space is limited. They hide under the bottom wall of a wall cabinet or in a countertop. The latter in working order have a vertical position.

In kitchens with a minimalistic design, high-tech, neoclassical T-shaped hoods are suitable. Models of the fireplace type complement well the classics, Provence.

Among the inclined models are:

• Bosch DWK065G20 is very economical (class C). Air suction is enhanced, as there are additional openings around the perimeter, the capacity is 530 cubic meters per hour. Does not have a check valve.
• Krona LIVA S 600 extremely quiet (noise level 38 dB), productivity 550 cubic meters per hour. 7-year engine warranty. There is a check valve, perimeter suction, inexpensive. Works in two modes, at three speeds.

Of the domed ones, Pyramida KH 50 IX has proven itself well, with a throughput of 600 cubic meters / hour, it makes a lot of noise at high speeds (58 dB). Combines two modes; an additional carbon filter can be installed for recirculation. A check valve is included in the package.

Maunfeld Urania 53 got into the TOP 10 for 2020. Large productivity 1250 cubic meters / hour, four speeds, additional suction around the perimeter, check valve. Noise up to 52 dB, which is acceptable for such a powerful model.

Over-island model - Ventolux Isola Cube 1200. Super powerful (1200 cubic meters / hour) with small sizes 35 and 39 cm. Lighting is provided by halogen lamps, due to which the device does not overheat. Operation only in exhaust mode, the check valve protects against the ingress of air from the ventilation shaft, which was in the bathroom or from neighbors in the kitchen.

T-shaped models do not lose popularity:

• Siemens LC66BHM50 is economical (consumes 136 W). Works in normal mode (low noise, 368 cubic meters / hour) or intensive (noise 69 dB, 605 cubic meters / hour).
• Elica JOY BLIX / A / 60 has a filter clogging indicator, three speeds, you can switch to intensive mode, dimensions above average 60 and 47 cm. Cleans 600 cubic meters / hour, has built-in halogen lamps.

For small rooms, you can consider the following options for exhaust devices:

• Gorenje BHP623E12X productivity 368 cubic meters /час. Three speeds are provided, there is a check valve, can recirculate air. Quite noisy (71 dB). Has a pull-out panel, LED backlighting.
• Eleyus Line I 50 WH handles 380 m3 air flow. / hour. Three speeds, can function in recirculation mode. Incandescent lamps, noise up to 65 dB, reasonable price.

Everyone chooses a device to their taste: in some cases, the most important thing is quiet operation, in others compactness, high power, low price. Appearance is always important, the device must be combined with the design of the room. It is also important that the device cleans the air efficiently in specific conditions.
