Installing a hood under a cabinet. Review: how to install a hood in the kitchen - preparation and installation rules. The nuances of installing a hood

It is not for nothing that the word “hellish” is often added to the word “kitchen”. Steam, boiling brew, hot oil - all these are attributes of cooking processes. And if you don’t want to do a thorough cleaning of the stove and cabinets near it very often, buy and install a hood. Our instructions will tell you how to install a hood in the kitchen correctly.

Everything has its turn

No matter how the designers try to distinguish themselves from each other by talking about convenience different systems, coming up with separate names for them, but in fact there are two types of hoods:

• Exhaust;
• Recirculation, or as they are also called air purifying.

In the first case, air and steam, without remaining in the system, are expelled from the room into ventilation system and out.

In the second case, the same ingredients, having passed through a system of carbon filters, are returned to the kitchen in the form of air purified from fat and moisture. The process of air return or recirculation occurs.

Pros and cons of each system

There is no clear answer to the question which system is better. Each of them is good in its own way, but also has disadvantages. Therefore, before deciding on the question: how to install kitchen hoods, decide on the type of hood.

Let's talk a little more about this.

1. According to installation schemes, a recirculating hood will certainly benefit. It does not require the installation of additional hoses for air exhaust and everything that comes with it.
2. In terms of removing odors and steam, exhaust ventilation is the leader here. The explanation for this is very simple - everything that enters the system is immediately removed irrevocably. With a recirculating system, the smell will go away and settle on the filters, but excess humidity will remain.
3. In terms of heat retention, especially in winter period, the palm will remain with the recirculating hood.
4. In terms of economical use - better exhaust systems. They do not require replacement of carbon filters and, accordingly, additional financial costs for maintenance.
5. In terms of noise level, the exhaust system operates more quietly; it does not need to waste its power on pushing the air flow through the coal grate.

Some people prefer not to waste time installing the hood with their own hands or simply do not have the necessary skills, others do not have the right tool or simply lack the desire to study physical work. But there are always craftsmen who do all the housework or try to do it themselves. In practice, installing a hood is very easy job, and you can even do it alone without an assistant.

General requirements

A hood, like a stove, is a must in the kitchen

First you need to make sure that you have chosen a suitable hood. Its width should be the same as the width hob gas or . The power of the hood must correspond to the area of ​​the kitchen, since if the performance is insufficient, the hood will not be able to clean the air from combustion products and unpleasant odors. In addition, it is important to consider the correct one.

Depending on the type of hood, you should prepare in advance the place where it will be installed. If it is a dome hood, there should be a place for it above the stove. For a built-in hood, you must order a cabinet in advance. They are usually made in furniture stores to order, for this it is enough to provide furniture assemblers with instructions for the hood: they indicate detailed dimensions Your model, focusing on which the cabinet will be made. These parameters are not important for you.

In some cases, a furniture company may ask you to leave the hood while the cabinet is being manufactured and assembled. If there is such an opportunity, agree. This way the master can try it on right away ready-made wardrobe to and in case of misunderstandings or if a mistake was made when creating such a cabinet (which among professionals - very rare) everything can be fixed on the spot, saving time.

Modern hoods are very stylish

If you are going to install a regular wall-hung hood, it is enough to leave only free place, but there is an option not to leave the hood open, but to make a special cabinet for it. Unlike the cabinet for a built-in hood, this element of furniture will be more of a decorative character. The photo shows that the cabinet has no bottom horizontal line, since your hood will be placed in this currently empty niche.

Dome hood is one of the most powerful

The dome hood is mounted according to the same principle - the whole process can be seen in the video:

IN this material The master uses an additional block, since in this particular case the gas pipe interferes with it.

It’s more difficult with non-standard hoods: in these cases, the process itself will be special. This system is attached to the ceiling using dowels and special fasteners.

The main difficulty in installation lies in the installation of the air duct: it will have to be routed along the ceiling, fixing it at certain intervals. It is advisable that the exhaust path be as straight as possible, without bends or corners: this may affect the performance of the hood.

If the room is small, you can get by.

Samsung hood review and installation:

• Having measured distance from hood to ventilation shaft , stretch the corrugation to the required length;
• Secure one end of the corrugation at the base of the hood outlet;
• When laying the corrugation along the wall cabinets to the ventilation hole, do not damage the corrugation: in fact, it is just a very thick foil, so you can crush or tear it when careless handling very easy;
• Insert the end into the grille hole.

While cooking food, fumes and various fumes rise from the stove to the ceiling. After some time, it becomes difficult to breathe in the room - this means that the polluted air is not drawn out well enough through the vent. Therefore, it is necessary to install a kitchen hood for forced air circulation. But first you need to decide what operating mode of the unit is required in your case, and then how to install the hood in the kitchen correctly.

Devices forced ventilation for the kitchen differ in operating mode. The units are:

1. They pump contaminated air through a block of filters, consisting of a preliminary filter (for rough cleaning) and a carbon filter (for cleaning the air from odors). Such a unit does not require a connection to a ventilation duct, so in this case installation will be the easiest. But, in terms of the quality of air purification in the room, this type of device is inferior to flow-through devices.
2. effectively pump out polluted air from the room into a ventilation shaft or channel, which is discharged outside (if you install a hood in a private house).

Required device power

Connection neutral wire to dead neutral

There are several types of air ducts for domestic ventilation on sale:

1. PVC (plastic) air ducts. They have good strength and light weight. Thanks to the smooth coating, they do not create noise when flows move along them.
2. Aluminum corrugated the air duct bends freely, stretches and is easily adjusted to any size. It does not create vibration or hum, but has an unaesthetic appearance, therefore, it is usually hidden in a closet, a special box, or hidden by a suspended ceiling.

Before installing a hood in the kitchen, make sure that you do not cover the only standard vent in the room with a pipe. In the case of one vent, they often make another exit from the mine and place check valve, which will close the stream into it when the device is turned on.

There is also the option of using a special box with a clapper valve.

On the image installed valve has a red color. When the fans are turned off, it lies horizontally, and air can freely flow through the box naturally. When the fans are turned on, the valve rises and blocks the air outlet back into the room, thereby directing it into the shaft. The material can be some lightweight material, such as plastic or aluminum. But this option is not suitable if a built-in hood is installed, since it is mounted in a wall cabinet.

For private houses the best option will punch an additional hole in the wall for the channel and not affect the existing vertical one. The air duct from the device must be routed into the additional hole. But at the output it must be installed check valve, preventing outside air from entering.

Check valve

If in ordinary apartment there is no additional channel, and punch a hole in external wall is not possible, then this channel can be expanded and a special adapter, having two holes.

Through the lower grille, air from the room enters the shaft due to natural draft. At the same time in top hole there is a visor that prevents the air flow from the unit from escaping through the grille back into the room. Although there is of course a return leak, it is minimal compared to the outgoing flow.

The figure below clearly shows how the air duct is connected to the adapter, while maintaining natural draft.

Thus, installing a kitchen hood with your own hands is only possible for home craftsmen. Completing the task requires accuracy and attention. Well, for those who do not have the skills to use tools, or do not have free time, the best option would be to invite a specialist to resolve this issue.

These days it’s hard to even imagine modern kitchen without a kitchen hood, which serves to effectively remove combustion products, kitchen aromas and fumes. Today's modern market abounds in a great variety of hood models, which differ in the installation method. Today we will talk about how to correctly and competently install this electrical device.

First, you need to decide on the height at which the hood will be located. Since, if you install it at an excessively high height, the electrical appliance will not work effectively. This means that all vapors and odors will remain in the room. If the hood is mounted too low, it will interfere with work at the stove, and may pose a risk of ignition of grease that has accumulated on the filters over time. The most reasonable thing would be to install the device at a distance 75 cm from the gas hob to the bottom panel of the hood. From an electric hob, 65 cm will be enough.

Connecting the hood to the duct.

Also, before installing the hood, it is necessary to consider how exactly the air will be discharged through the ventilation duct. In most cases, the architecture of the room and placement in it kitchen furniture do not allow you to install the hood near the ventilation hole. In addition, air ducts having big number bends (knees) increase the noise level and significantly reduce the performance of the electrical appliance. It is also necessary to ensure that after installing the air duct, the ventilation duct is not completely blocked.

For this purpose, special grilles are installed on which there is a place for attaching the air duct, as well as a special valve. When the hood is operating, the valve closes, and when it is not working, the valve opens to ensure natural air circulation.

If the dimensions ventilation duct do not allow the installation of such a grille, then you can use an air duct with an installed check valve.

Types of air ducts.

Air ducts can be divided into corrugated and plastic. Corrugated air ducts are made from thin sheet aluminum. To install such ducts, a grille with a fitting and a clamp are required.

During installation, the air duct is stretched to establish the required length. If unstretched folds of the air duct remain, the operation of the hood will be accompanied by an increased noise level. Corrugated air duct is relatively cheap and easy to install.

Plastic air ducts come in rectangular and round cross section. Air ducts with rectangular cross-section are less noticeable and can also be placed on wall cabinets in kitchen furniture.

To install a hood with a plastic air duct, you must have L-shaped adapters and adapters specifically designed for the ventilation duct and the electrical appliance itself. Such air ducts are distinguished by the absence of noise during operation of the hood. Dirt also does not get into them due to the absence of holes and cracks.

The nuances of installing a hood.

You should know that the device will be installed technically correctly if the diameter of the air duct is larger than the outlet of the hood itself. If you do not adhere to this rule, the load on the unit’s engine increases, noise appears and the efficiency of the device decreases.

Before installing the hood, it is preferable to first install the furniture in the kitchen, or make precise markings of it. This will allow you to determine the location of the outlet, as well as the placement of the air duct. Since hoods come with fairly short cords, the socket should not be located too far away. It is also not allowed to squeeze the cord, place it close to the stove, or sag.

Layout of electrical outlets in the kitchen.

What types of kitchen hoods are there? Types of hoods.

The installation of a hood in the kitchen will depend on the type of hood chosen. The following types are distinguished:

• Dome hoods are the most powerful, they resemble an umbrella from which a pipe extends;
• Hanging (also called flat and standard) - mounted under the cabinet above the stove.
• Built-in – installed inside a wall cabinet or in a table, so they fit perfectly into any design.
• Wall-mounted - mounted on the wall above the stove, may have different design housings.
• Corner – installed in a corner.
• Island hoods – designed for kitchens with an island. You can fix it anywhere in the room by hanging it from the ceiling.

Kitchen hoods may differ in design and technology.

In addition to the type of design, hoods differ in ventilation mode.

• Flow-through draw polluted air from the kitchen into the ventilation shaft. This method of ventilation is called air exhaust (exhaust mode). It is the most efficient and productive.
• Recirculating hoods– pass air through carbon filters in the housing, resulting in Fresh air. It does not require ventilation in the kitchen in the apartment, so its installation can be called simpler, but less effective in terms of cleaning.

Calculation of kitchen hood power.

An important parameter when purchasing a hood is its cleaning performance, which is measured in cubic meters at one o'clock. As you might have guessed, this value shows how many cubic meters of air the hood will pass through itself per hour of operation. According to the standards established in Russia, the air in the kitchen must be renewed 12 times per hour. Therefore, you can easily calculate how much power you will need using this simple formula:

Kitchen area * Ceiling height * 12 times

It is also worth taking into account the reserve for power loss due to bends of the air duct, the length of the ventilation shaft and other parameters; for this, add 30% to the result obtained.

For example, if your kitchen has an area of ​​6 square meters. m. and the ceiling height is 2.5 m. then the calculation will look like this:

6 * 2.5 * 12 * 1.3 = 234 m3.

Advice! Also, when purchasing, you should take into account the noise emitted when the ventilation is on, which manufacturers indicate in decibels. You should not buy models that produce noise above 50 dB. There are practically silent hoods with two fans or one external one. In addition, some models are equipped with sound-absorbing pads.

It is well known that exhaust devices installed above kitchen stove, are used to remove exhaust gases and unwanted odors arising during the cooking process. The efficiency of air purification and the possibility of keeping it in the kitchen largely depend on the model of the exhaust device you choose. comfortable conditions for accommodation. But before you hang the hood over the stove, you should thoroughly study the basic requirements for its installation technique. This issue is of particular importance in a situation where you have a gas stove, the operation of which is always associated with increased risks.

It is believed that the method of installing an exhaust device is quite simple and can be mastered by anyone. That's why in this article we would like to introduce you to the installation technique kitchen hoods with your own hands.

Types of exhaust devices

All known species exhaust devices can be divided into two large groups:

• circulation devices with built-in carbon filter;
• hoods built into the existing air exhaust system.

In models exhaust equipment with a filter element, air purification is carried out by its forced circulation within the device.

In this case, contaminated air first enters the system, and after cleaning in the built-in filter, it is returned to the kitchen space. Such models of exhaust devices are most often installed in small kitchen areas.

In kitchens big size It is advisable to use hoods with a forced air intake mechanism, the output of which is connected to current system ventilation. With the help of such partings, polluted air is removed from kitchen space outside (outside the premises). The operating efficiency of such exhaust devices is noticeably higher than that of partings with forced circulation air, so they are most often installed in kitchens with a large number of sources of pollution.

To successfully install hoods with your own hands, you will need to follow the following rules:

• distance from the slab to the intake casing (plane inlet) the hood should not be less than 65 centimeters;
• the dimensions of the intake casing should approximately correspond to the dimensions of the gas stove;
• used to connect the hood electric outlet should not be located directly above the stove;
• When connecting the hood to the air duct, its outlet pipe should have a minimum of bends.

Installation

Installation of a hood with a built-in carbon filter will not require any special skills from the performer and special effort. To install it you will need good level, with the help of which control points for hanging the device are marked at the selected height, and then holes are punched for the fastening elements using a puncher.

The hood is fixed to a wall or wall cabinet using special hooks that securely hold it at the suspension points. When installing an exhaust device on the front part kitchen set To place it, it is best to use niches that are always available in wall cabinets.

The housing of the hoods with connection to the air vent is fixed using the same fasteners (hooks), with the only difference being that their installation location must be “tied” to ventilation hole. After fixing the device in the selected location, an air duct channel is attached to its outlet (ordinary plastic pipes can be used as such a channel).

The main thing is that the pipes you use are sized to match the diameter of the air intake hole in the wall, which will allow you to avoid losses in pumping power. Upon completion of all installation procedures, you should conduct a test check of the operation of the equipment, which will allow you to ensure that it has been installed correctly.

If you need a separate outlet to connect the hood, all the wires supplying power to it can be “hidden” in a special cable channel. In addition, electrical wiring can be hidden under sheets decorative material used to decorate your kitchen.

Note! It is necessary to provide a special protective device(the so-called “automatic machine”), which ensures that the equipment is turned off in the event of an emergency.

We really hope that our article will help you figure out how to hang a hood over the stove in such a way that you will forever get rid of unpleasant odors in the kitchen and be able to enjoy fresh and clean air.
