Every housewife will agree that having a hood in the kitchen is an undeniable convenience and even a necessity. It helps to get rid of cooked food odors in a timely manner and normalize the temperature in the room. However, is it so difficult to make a kitchen hood with your own hands? In this article I will tell you how to save your family budget by building this important kitchen attribute yourself.

Preparatory work

The operating principle of a kitchen hood consists of two actions: the outflow of exhaust air and the influx of fresh air. Installing a hood does not make sense if the ventilation in the apartment is disrupted. Therefore, the first step in installing a kitchen hood will be to check the ventilation draft. A popular test method is a lit match. Hold a match to the vent and observe the behavior of the flame. If the tongue tilts towards the pipe, then the ventilation is in order; a direct flame location indicates problems with ventilation; a tilt away from the pipe indicates reverse draft. However, professionals do not recommend using an open flame to check ventilation draft. The fact is that there may be an accumulation of flammable gases inside the pipe. Incorrect actions can lead to dangerous situations, so use a small piece of paper or tracing paper to check it yourself.

If there are any ventilation problems, fix them first. Cleaning pipes from an apartment is only possible superficially; it is safer to call a specialist for this work. When ventilation is restored, proceed with the installation of the kitchen hood. Before starting construction, decide on the type of kitchen hood you are going to install:

• Passive kitchen hood. It works using upward draft and is suitable if there are no ventilation problems.
• Active kitchen hood. Forced removal of exhaust air using an electric fan.

Hood installation

Start by drawing up a drawing of the kitchen hood and calculating the required amount of materials. The choice of materials for a kitchen hood is individual depending on preferences, but the general list is unchanged. You will need a metal profile and sheets of plasterboard for the frame of the hood, finishing materials, a corrugated pipe for the air duct and consumables. Let's take a closer look at building a hood with your own hands.

• Using the drawing, mark the location of the future hood on the wall. Use the following dimensions: the width and depth of the hood is equal to the width and depth of the hob, the height above the induction and electric stove is 65-70 cm, above the gas stove - 75-80 cm. Don’t forget to leave room for the ventilation pipe.
• Start creating the hood frame from the top level from a metal profile. Use anchors to attach the profile around the vent. Lower the vertical members and crossbars. Connect to the lower level.

• Connect the air duct to the ventilation hole using a corrugated pipe. Try to avoid turning the pipe; with each bend, the traction efficiency decreases by 10%. To reduce noise when the hood operates, wrap the pipe with soundproofing material.
• Cover the frame with plasterboard and complete the work with a final finish that matches the style and color scheme of the kitchen.

It’s easy to convert the resulting passive hood into an active one: install filters and an electric motor with a fan inside the frame.

Before starting work, read the advice of repair specialists to avoid mistakes during installation.

• The fastest and easiest way to finish the exterior is to use drywall, putty in the corners and final painting or whitewashing. Depending on the style of the kitchen set, replace drywall with plywood, add decorations with a wooden baguette or polyurethane baseboard.
• Mark the hood with the kitchen in place. This method will help avoid errors in calculations.
• If you place the box inside one of the kitchen drawers, the hood will be hidden from prying eyes and careful finishing will not be required.
• The cord from the active hood should not sag or be in close proximity to the gas stove. The best and safest solution is to prepare the cable in advance.

The DIY kitchen hood is ready. Do not forget to open and clean the inside of the box every six months from settled fat, dust and unnecessary debris.

In order for a kitchen hood to be made correctly with your own hands, no professional construction education is required. You just need to carefully study the materials presented below.

Scheme of the principle of air purification: a - flow; b – circulation.

It is a very common occurrence when you start renovating your kitchen and are surprised to discover that the kitchen hood is completely unsuitable in size or design. Of course, such a problem will not bring joy. And it will require a solution. By making a kitchen hood yourself, you can significantly save your finances, which you would have spent on purchasing a finished product. But it will take you much more time to make a hood than to install its factory counterpart.

What you should know about kitchen hoods

You should have an idea of ​​how this unit works. The word “drawing” itself implies a process during which something is drawn out. And this “something” is polluted air.

Most hoods do not just draw in dirty air, they process it using filters and release it back, already purified. Some models simply remove contaminated air through the ventilation system to which they are connected.

Important! If you decide to make a hood yourself, be sure to make sure that the ventilation ducts in your home are in good working order.

When the ventilation is clogged or partially dirty, the traction force is reduced. And sometimes it’s completely absent. Consequently, the hood will not be able to cope with its task at the maximum level. To help the appliance work, you should clean the home's ventilation system and provide additional air flow into the kitchen during operation.

Rule: if your house has windows with a high level of tightness, set the minimum ventilation mode thanks to special valves for ventilation.

Types of kitchen hoods:

• active;
• passive.

The first type of kitchen hoods involves devices that have a built-in electric motor. They have proven to be excellent pulling devices. But they also have drawbacks. For example, high energy consumption.

The second option is a simpler hood model. The operating principle is to remove contaminated air using an internal motor and fan. But a prerequisite for high-quality operation of the device is maintaining the ventilation system in perfect technical condition.

Hood manufacturing process

It can be divided into stages:

1. The first stage is the preparation of materials and equipment. If something from the above list is missing, you should visit a hardware store. Equipment can be rented.
2. The second stage is applying markings. In order not to spoil the aesthetic appearance of the room, you should carefully take measurements. It will be necessary to equip not only the hood. You should also place an air duct. It can be carefully disguised using drywall. The simplest marking option is obtained when the hole for ventilation is made from above the slab. When the hole is located elsewhere in the kitchen, you will need to place a box in which the air duct pipe will be laid. Advice! If you plan to finish the ceiling with plasterboard in your kitchen, you can partially hide the air duct under it.
3. The third stage is creating a frame for the air duct. This will require galvanized metal profiles. Using anchors, they are secured along the entire perimeter of the future air duct. It's good if the pipe runs in a straight line. In cases where this option is not possible, the profile should be fixed with bends in the required places. Markings for the air duct are applied on the ceiling. The first profile, which serves as a start, is laid down in several separate parts. They are attached using self-tapping screws.
4. The fourth stage is the completion of work on arranging the plasterboard box. To complete the work, you will need to attach a second panel from the primary profile to the already completed hanging parts. You used it as a starting point for work. When the lower part is ready, transverse type strips are mounted on it. They should subsequently be covered with plasterboard.
5. The fifth stage is the formation of the kitchen hood body. So, when all the rough work is done, you can begin arranging the hood itself. The lower part of the future appliance is fixed to the kitchen walls. It is also made from a profile. If your kitchen has a niche for the hood, this will make the task even easier. Otherwise, you will have to additionally attach the lower part to the main box from the sides. All parts of the hood are cut from a metal profile and connected to the lower part. To make the structure more rigid, you will need to strengthen the sides with jumpers. They are also made from a profile.
6. The sixth stage is connecting the air duct to the ventilation system. This is done using a corrugated pipe. Important! In order for the hood to operate with minimal noise, the air duct pipe should be wrapped in material with a high level of sound insulation. If you have checked your ventilation system and know that it is faulty, you should contact a specialist. They will clean the channels, which, in turn, will provide good traction force in the ventilation in the future.
7. Stage seven – finishing. To complete the procedure for finishing a kitchen hood, its body and the box in which the air duct is located are sheathed with plasterboard. Then putty is applied to the finished structure. With its help, fasteners and plasterboard seams are masked. After this, the hood can be painted. Some prefer other options for decorating this kitchen appliance.

The hood is a very important element of a modern kitchen. Many housewives save on the hood or simply do not install it as unnecessary, but in vain!

A kitchen hood blocks unpleasant odors, steam and grease, preventing them from settling on furniture, household appliances and other interior items. And for studio apartments, a hood is simply necessary.

The most important thing in a kitchen hood is its performance, because it organizes continuous air processing for an hour.

To determine the performance, you need to multiply the area of ​​the room by the ceiling height and by the air replacement factor from 6 to 10. The instructions for any device indicate the performance of a specific model.

The modern appliance market offers a wide range of kitchen hoods. Let's try to understand all the diversity of this much-needed attribute of a modern kitchen.

Depending on the mounting method, hoods are divided into:

Dome

The simplest, but at the same time powerful, dome-shaped hoods that are mounted above the stove.

This type of hood is also called passive. The dome hood does not have fans, complex sensors or other mechanisms in its design - hot air rises upward through upward draft.

Modern domed hoods are made of tin and decorated with glass and wood.

In terms of style, dome hoods resemble part of a fireplace chimney and look beautiful and laconic.

The disadvantage of passive hoods is that they only work if the ventilation pipes are in working order and may be useless if the ventilation ducts in an apartment in an old building are clogged.

It is better to use a dome hood in a large kitchen in a private house, where additional heating appliances operate. In this case, the air duct can be routed through the wall.

Flat

Flat hoods are compact in size, but at the same time they are no less effective in operation than dome hoods.

This type of hood has replaceable carbon or acrylic filters. Flat hoods are ideal for small spaces; they look stylish and beautiful, while at the same time they have significant power and good performance.

In addition, flat hoods are quite easy to install. The only disadvantage of such a device is that the filters need to be changed very often, which requires additional expenses and is not very convenient.

Built-in

Such hoods are mounted in the kitchen cabinet.

They do not take up much space, fit well into the interior and are almost invisible.

Built-in hoods are modular and telescopic. Modular hoods are small in size, and telescopic hoods are additionally equipped with a retractable panel. Built-in hoods can be installed independently, but, as a rule, kitchen furniture manufacturers install built-in hoods during the production of furniture.

Flat and built-in hoods are called active, since they are powered by an electric motor and are equipped with filters.

If the kitchen area allows, and the working surface of the stove is located in the center of the room, then it is better to prefer an island hood above the stove.

All that remains is to resolve the issue with the air duct.

Features of work

Depending on the method of operation, all kitchen hoods can be divided into those that remove air and those that purify it.

For those who, for whatever reason, have never had a kitchen hood and are thinking about purchasing one for the first time, it will not be easy at first to understand the wide variety of assortments. To clarify, let's look at each design in more detail.

Flow-through

These hoods, through the existing ventilation outlet, rid the room of air saturated with steam and grease.

Consequently, the operation of such a hood directly depends on the degree of cleanliness of the ventilation duct.

Flow hoods are mainly dome models, quite large in size. Flow hoods are highly efficient and very noisy, which can be a serious problem for those with sensitive hearing when such people spend a long time in the kitchen. In connection with this fact, modern flow-through hoods are produced with two fans in order to reduce the noise level without reducing their power.

Such hoods, which are additionally equipped with filters for cleaning, will cost many times more. Therefore, this type of hood is increasingly being made independently (the features of making a hood with your own hands are discussed below).

Flow hoods are a wonderful design element, and made of glass, such models look very impressive.

Circulating

The operation of circulating hoods is based on air purification using filters: metal and ordinary carbon.

The first ones eliminate the smell of food in the kitchen and apartment, are easy to care for - they just need to be washed, the second ones purify the air, and they require periodic replacement approximately once every 4 months.

The most important advantage of the circulation type of hood is that they purify the air already in the room; when the windows are closed, there will be no shortage of oxygen, and the ventilation operates as usual.

This type of hood is easy to install: there is no need to connect the hood to the ventilation, you just need to install it at the desired level and plug it into a power outlet.

A properly installed circulation hood can work effectively despite its compact size. Thanks to the built-in filters, these hoods have good noise insulation.

Nowadays, the most popular are hoods that combine both air extraction and circulation, so the owner can independently choose the most suitable mode for him.

How to make it yourself

In consumer electronics stores, you can purchase a ready-made hood for every taste based on your preferences for its configuration, but, as a rule, good models are not cheap.

In order to save money, you can make a kitchen hood yourself; it will be less expensive in price; moreover, a hood made by yourself will be the most ideal addition to your kitchen, akin to a work of art.

You can make both a passive and an active hood yourself. Let's consider both options.

In order to make a dome hood you will need the following materials and components:

• galvanized U-shaped profile, diameter 15 mm;

• drywall, tin, non-flammable plastic, thick foil - any of these materials for making a box;

• batting or other soundproofing material;

• corrugated hose with a pipe (in case the ventilation hole is located away from the hood);

• check valve;

• dowels, perforated corner, measuring instruments, as well as putty and paints and varnishes for improving the hood.

photos

Before you start making the hood, you first need to identify a place for its installation. You should adhere to the scheme according to which the hood should be located at a distance of at least 65 cm from the hob, and the width of the hood corresponds to the width of the stove.

You can install the hood directly above the stove, if the ventilation hole is also located there. If the ventilation is located to the side, you will have to use a corrugated hose to “pull” the hood to the ventilation hole.

Many people provide homemade hoods with ventilation; in this case, you need to remember about grounding. In addition, the hood will require a separate outlet.

Having decided on the location for the future hood, you can begin to manufacture it.

At the first stage, make a rectangular frame from a pre-prepared galvanized profile, one and a half times smaller than your stove. It is necessary to nail it to the ceiling using dowels.

Next, at a height of 65 cm from the slab, nail another profile equal to the width of the slab in a horizontal position. Based on this profile, assemble a frame in the form of a bell along the width of the slab; this will be the design of the hood. For the first time, install a support under the lower frame so that it does not fall off, and also connect the rectangular frame that you attached to the ceiling with the lower one using the side ribs.

The resulting dome-shaped frame should be covered with plasterboard or any other fire-resistant material.

When the ventilation hole does not get inside the dome, it is necessary to pull it to the hood using a corrugated hose. Connect the corrugated hose to the hood with a pipe and weld it (if the hood is made of tin) or secure with sealant (if using plasterboard as the hood material).

In order to prevent air from the ventilation or from the street from penetrating into the apartment through the hood, install a specially purchased back pressure valve.

If the hood is made of plasterboard, the final step will only be to refine it. Be sure to cover the corners of the hood with a metal profile corner so that they do not crumble during operation. Putty all joints and fastening points. The finished hood can be painted in the color you like or decorated in any other way. Thus, you can make a hood that perfectly matches the interior of your kitchen.

A kitchen hood is a must-have element. It helps get rid of unpleasant odors and remove excess steam that occurs during cooking. Of course, it becomes an integral part of the interior. In the process of renovating or re-equipping a kitchen, many are faced with the problem of choosing a hood. Often this part simply does not fit in size, appearance or other parameters. But in fact, the problem can be solved very simply. A DIY kitchen hood will have the required dimensions and be unique. It's not difficult to make.

Types of hoods

Before considering the question of how and from what to make a kitchen hood, you should first understand a little about the operating principle of this device and the types available. Such an integral attribute differs not only in design, installation method, but also in operating principle. Today, the following types of kitchen hoods are distinguished:

• dome - they are mounted directly above the gas stove. Basically, they are all of the same type, having a cone shape with an air duct pipe.
• flat – have very compact dimensions. They do not have a built-in air duct and operate using built-in replaceable filters. A flat hanging hood for the kitchen is an ideal option for rooms with a small area. These small devices look very stylish and modern and at the same time are quite efficient in operation and very mobile. These hoods are the easiest to install.
• built-in – mounted inside the kitchen unit, do not take up much space and fit into any interior. These devices can be of the following types: modular and telescopic. The first option has small dimensions, but the telescopic kitchen hood has an exhaust panel and is built into the kitchen cabinet. Both options work due to replaceable filters.

In addition to the types, the operating principle of hoods should also be highlighted:

The disadvantage of this operating principle is the frequent change of filters. These models often have special carbon filters installed. Of course, they clean the air well, and most importantly eliminate unpleasant odors, but they also have a short service life. Therefore, these systems are distinguished by lower cost than flow-through systems and also lower operating efficiency.

It is worth adding that most models are connected to the network to improve performance. An electric kitchen hood must be connected to a separate grounded outlet.

Based on all of the above, we can conclude that in terms of performance, devices with an active type air duct (with forced air outflow due to a built-in electric motor) are the most functional and effective option.

So, when you decide on the type of hood, you can consider the idea of ​​how to make a kitchen hood with your own hands.

If you have a ventilation system, then you can easily build a device with passive ventilation through an air duct. If there is no such system in your home or it is not provided for the kitchen, then you can consider the option of creating a device yourself with active ventilation using a built-in electric motor.

The simplest and most inexpensive option for making a device for air purification in the kitchen is a model made of plasterboard. What you will need to make this device:

1. Sheets of drywall, preferably a brand with increased moisture resistance.
2. Metal profiles.
3. Metal corners.
4. Corrugated pipe for air duct installation.
5. Materials for finishing the dome hood (paint, putty).
6. Material for air duct insulation.

Step-by-step manufacturing instructions are as follows.

1. Initially, marking work is carried out. Be sure to keep in mind that on the wall you will have not only the device itself, but also the air duct to it. It is advisable to hide it inside a plasterboard structure. The appearance will be much more aesthetically pleasing.
2. Next, a frame for the air duct is made.

• The pipe box must be attached to the wall using a building level. First, the top bar is installed. If you decide to make a curved box, then do not forget to cut and bend it before attaching the profile, giving it the shape you need.
• After installing the starting profile, the vertical elements are lowered down.
• Vertical fragments are secured with a lower bar made of the same profile. Don’t forget to attach the transverse strips to it that are necessary for attaching the gypsum board walls.

The rigid frame of the box is also assembled from the existing galvanized profile. To simplify the work, immediately before assembly it is necessary to make a detailed drawing and calculate the hood for the kitchen. All dimensions should be indicated on the drawing so as not to make mistakes during the manufacturing process.

When making the frame, be sure to pay attention to the additional crossbars. They are usually attached to the side. Jumpers are necessary to give rigidity to the structure.

Before covering the duct, you must first connect the corrugated pipe duct to the vent. Before connecting, make sure that the exhaust vent is working and there is draft.

Box finishing

For the kitchen it can have a wide variety of shapes. Galvanized profiles and plasterboard allow you to create a wide variety of shapes. And, of course, the finishing will add even more uniqueness to your device.

The simplest and most effective way is:

• frame covered with plasterboard, reinforced with metal corners;
• putty, paying special attention to the joints of the sheets and the places where self-tapping screws are screwed in;
• paint, whitewash or decorate with tiles or decorative panels. Here only your imagination can come up with the design you need.

Materials

Of course, when creating a hood with your own hands, the problem arises: what materials to use? Here, in addition to drywall, you can also use plywood or MDF. To prevent the air duct from making too much noise, the pipe is usually wrapped in soundproofing material, and a galvanized profile is ideal for the frame of the decorative box.

To save money and for finishing, you can use wooden baguettes, painting them with stain to the desired color. You can use polyurethane decorative skirting boards. And even fiberboard sheets are suitable for the box.

Thus, you can create a unique work of art in your kitchen, and if you have an ordinary standard device that works quite well, then you can build a new box for it.

A DIY kitchen hood will help you use your kitchen space more functionally, even if you have a compact filter-based device installed.

Such a compact device can be built into a homemade rectangular cabinet. For the cabinet, you can build a small external shelf with a ledge and decorate it with materials that match the overall interior. Thus, new useful space appears. And a disguised hood looks much more aesthetically pleasing than a separate device installed above the stove. With the appropriate approach and low costs, you can create a truly unique version of the exhaust device.

In order for a private house to receive an influx of fresh air, as well as remove already polluted air, it is necessary to install a ventilation system - an exhaust hood, which can be natural, forced or combined. But regardless of the choice, ventilation will perform its function only if preliminary calculations are made that take into account the size of the room and the features of the future system.

Natural ventilation

At the design stage of a house, a natural ventilation scheme must be drawn up. The principle of its operation is to ventilate the house due to the natural circulation of the air mass. In order for the system to perform its function properly, the influx of fresh air and the exhaust of already humid air must be carried out through different rooms. Typically, the space through which air enters is called dry, and the outlet space is called wet.

You can ventilate your house in four ways:

• channel, when the house is equipped with vertically located channels.
• ductless. This method can be used for residential buildings, but it is more suitable for industrial buildings.
• permanent. In this case, the premises are provided with a significant air flow, which enters through air ducts.
• periodic, when “new” air enters at certain intervals.

To increase the level of air exchange in the house, special fans are installed on the exhaust ducts, which can operate either continuously or at set times. Accordingly, such equipment requires a connection to the power supply network.

Advantages

According to the principle of operation, it is divided into:

• supply and exhaust, carried out using special equipment. Another variation of this method is the installation of recycling equipment. In this case, the exhaust air passes through filters, is partially mixed with street air, and then, already purified, is returned to the room;
• supply air with the possibility of heating. To operate the system according to this principle, a recuperator is required, which uses exhaust but already heated air;
• supply air with cooling. Air conditioning is required here;
• supply and exhaust. The most common system for private homes. The circulation of air masses is ensured by the installed equipment in combination with elements of natural circulation. This air exchange scheme is relatively easy to install and quite effective.

However, the operation of the forced system is carried out by connecting its devices to the power supply network. In addition, the design and calculations of the system are carried out at the stage of drawing up the house construction plan. All components of forced ventilation perform different functions, but the main and only task of all elements is the supply of fresh air to the premises and the removal of already used air to the street.

The compulsory system includes the following elements and equipment:

• grilles to protect ventilation ducts from rodents, insects and debris;
• filters that prevent dust and pollen from entering the house;
• air valves that regulate the flow of air supplied to the house. In winter, protect the system from icy gusts of wind;
• fans used to create a continuous flow in the ventilation ducts;
• sound absorbers ensuring silent operation of the system;
• heaters that heat the incoming air;
• ventilation ducts that allow air to move.

How to properly install a hood in a kitchen in a private home

Manufacturers of hoods provide consumers with three main modifications of devices:

• hanging;
• built-in;
• dome or fireplace.

Also, according to the method of air purification, they are divided into devices that remove exhaust air to the street, and models that operate in recirculation mode.

But regardless of the material of manufacture and cross-section, the diameter of the air duct must coincide with the inlet of the hood. With a smaller pipe size, the kitchen hood will work in increased mode, which will lead to rapid engine failure.

The installed air duct should not completely block the opening of the natural ventilation shaft. To do this, a special grille is purchased and installed, the valve of which closes when the hood is turned on, and opens after the device has finished operating. This mode of operation allows the natural air circulation system to operate fully.

Ventilation in the bathroom and toilet

The task of installed ventilation in the bathroom is to clean the room from various odors and eliminate high humidity.

Since the operation of a natural hood is completely dependent on external climatic factors, it will not always be able to cope with its task. In addition, the absence of special grilles on the outside of the ventilation ducts makes it possible for small rodents and insects to enter the house. However, the natural air circulation system has its advantages, which include simplicity of design and relatively low price. The absence of complex mechanical elements in a natural hood predicts long and uninterrupted operation.

Forced exhaust fans installed in the bathroom can operate either from a light switch or have a separate power point. Device manufacturers also offer fans with built-in humidity sensors. In this case, the system begins to operate when the humidity in the room reaches a certain level. There are also models that are equipped with motion sensors that allow you to activate air circulation when a person enters the room.

Depending on the material used, decorative designs are:

• plastic;
• wooden;
• steel;
• made of MDF, chipboard or plasterboard.

However, when installing the box, it is taken into account that it will constantly be exposed to burning, fat and other by-products that arise during cooking. It follows that the structure must be washed and cleaned well. Only in this case will the decorative box fit into the overall design of the room.

Ventilation, both forced and natural, will perform its function only if the entire system is organized correctly. And to do this, it is necessary to take into account the size of the room and the climatic conditions in which the system will operate.
