Exhaust kitchen umbrella: how to install it correctly. Ventilation umbrella for the kitchen - device and features Principle of operation and varieties

Ventilation plant "Bastion" offers its customers quality products, manufactured on time. The company is one of the market leaders not only in St. Petersburg, but throughout Russia.

In this article we will tell you about the use of hoods in various conditions.

Principle of operation and varieties

In the kitchen of a modern housewife and in catering establishments, an exhaust ventilation hood or dome is installed. Its main task is to clean the air of the room from high humidity, odors, various impurities, the occurrence of which is associated with the cooking process.

The exhaust hood is component part quality system ventilation in the premises. Installation takes place over sources high temperaturein particular over slabs, hobs, open fire. The dome removes humid hot air, unpleasant odorsas well as soot, grease, soot, dust, chemicals.

Air purification from harmful impurities is also necessary in laboratories, in chemical and industrial industries, etc., where the production process takes place with release into space harmful substanceswhich can harm workers and the environment in general.

The umbrella is a domed structure, hence the second name - the dome. Connected to the ventilation system by an air duct. There are central (island) and wall-mounted, depending on the installation site.

Wall-mounted units are mounted directly on the wall. With a large weight, additional brackets are used for fixing. Central appliances are installed directly above the work surface, without touching the walls. Island umbrellas have a large carrying capacity.

A modern dome is not only a complex device, but also a decorative element. Factory facilities allow the production of umbrellas in accordance with the general interior of the room.

There is no fundamental difference in structure between household ventilation domes used in private households and industrial ones, they differ only in size and power characteristics. Indoor umbrellas have a common structure:

• Grease filter. It is mesh (made of a mesh with small cells) and labyrinth (a plate with grooves through which condensed fat enters a special compartment). The first type of filter is cost-effective, it is installed only in a horizontal position, it can be additionally equipped with a spark arrestor mesh, but it requires frequent cleaning. The labyrinth grease trap is installed only in an inclined position, does not require frequent washing.
• Spark arresting mesh. An obligatory element when installing ventilation domes over open fire sources, for example, over barbecues, grills.
• Pendants. Part of a mounting system that allows the umbrella to be fixed to a wall or ceiling, distributing the weight correctly.
• Turbines. The equipment is designed to induce the movement of air masses from the room. When installing, the center of the work surface and the dome should be correctly identified in order to achieve maximum efficiency. The section of the entrance of the exhaust hood must exceed the dimensions of the slab or other equipment over which it is suspended. Suspension heights vary from 0.7 to 1.1 meters.

When choosing a manufacturer of an exhaust hood, give preference to domestic factories, so you can save your budget, and the quality of modern products from a reliable seller is confirmed by certificates and quality control.

Last year I built myself a small workshop, which also serves as a storeroom for tools and equipment. Everything seems to be fine, but here come warm days, periodically turning into heat. And I forgot about natural ventilation. But this case is fixable. There are many options, I will describe one of them in this article.

Window and door openings serve for the natural exchange of air in a room, but it is not always convenient to keep windows and doors wide open. Additional source fresh air can be air ducts, or, as in my case, ventilation holes in the roof, on which umbrellas made of galvanized steel are installed, which are popularly called simply - a weather vane. We are starting to make our homemade ventilation. Correct markup is the key to success.

The umbrella should be installed so that on the back side of the roof, that is, from inside the room, the ventilation hole does not block anything: no rafters, no spacers, no lamps. If you don't understand how it works, here's a description. It is best to measure from the skate. They immediately estimated the size from the inside, and then transferred it to the outer roof slope. At the measured point we drill a hole in order to insert the blade of the cutting tool.

From this point we will make further marking. We try on an umbrella, remove its size from the lower round part and carefully transfer it to the place of future deployment. It is advisable to use a bold marker for marking so that the strip is clearly visible. In theory, all this should be calculated, but as a rule, in a private house, they make a middle section at random)

Considering that the roof covering consists of bituminous tiles laid on an OSB-board, which, in turn, is mounted on a solid lathing from a board, it is almost impossible to cut a hole with an electric jigsaw - the saw stroke will not be enough, and if it is enough, then it is very close and there is a possibility of it bend thoroughly. Since the hole has a circular cross-section, neither a circular saw, let alone a chainsaw, will make an even hole in size. Therefore, I chose an electric saber saw as a cutting tool. Very convenient and fast, the main thing is not to rush.

The hole is ready, you can start installing the ventilation hood. In order for the mounted vane to not have a powerful wind-blower and the wind did not hum in the empty pipe solo parts, it has an unusual shape. Its upper part is covered with a lid bent on four sides, so that one large hole is divided into four compartments. Warm air from the room will come out through all four holes, but it will blow in only one, depending on the direction of the wind. Install a piece of air duct from the inside and put on an umbrella on top.

To eliminate the possibility of rain moisture ingress on metal constructions ventilation umbrella, you need to carefully lift the roof covering and tuck the protruding support elements of the umbrella under it.

You need to do this operation only from that part of the base of the umbrella, which is located at the top of the roof slope. The lower part is installed directly on the roof covering.

The fact is that if you run the lower part under the roofing, then when it rains, water will accumulate in the formed barrier, and no matter how well you seal it, water will find its way and penetrate into the room.

After installing the umbrella, we fix it. Today there are a lot of hardware products that cut off moisture, but given that my ventilation umbrella is installed on utility roomI decided to attach it to regular nails. In addition, the umbrella will be subjected to wind pressure, and an ordinary nail is inherently a nag, that is, it has a small up and down stroke, and in the case strong wind the probability that the nail will cut the head is practically zero, which cannot be said about self-tapping screws.

The last but not least is the sealing of "weak" points. These are, as a rule, joints, adjoining of one structure to another and the place of installation of fastening elements. A special sealant must be selected: heat-resistant or heat-resistant. In the summer heat, the roof heats up so that, if desired, you can fry the eggs, so the sealant must also withstand such a temperature load. Apply sealant evenly around the entire perimeter with respect to weak points.

Well, the final touch is to smear the sealant in some places with your finger. You can take rubber spatula, but, I think, it is more interesting and better to do it with a finger. We have more

The root of the building troubles lies in the little things. Neglecting small details, a private homeowner ineffectively inflates the family budget with renovation costs. But if the owner treats the house as a whole organism, in which everything is interconnected, his money does not go down the drain, and the costs are limited to scheduled maintenance. Incorrect installation of safety devices on the chimney provokes losses - both financial and human.

Installing an umbrella on the chimney helps to maintain the heating system in optimal mode, prevent premature aging chimney, improve air circulation in the house.

Pipe caps and caps are designed for the following purposes:

• close ventilation ductprotecting it from rain, snow and dirt. Lack of protection can lead to the accumulation of a large amount of water in the chimney, which contributes to a decrease in draft and, accordingly, a drop in the efficiency of the heating system;
• protect the pipe material from damage by draining the accumulated condensate due to the presence of special grooves;
• do not allow insects and birds to fall into the pipe, serve as an obstacle for leaves and branches from trees;
• perform a decorative function. They give the roof a complete look, especially if the structure has elements of artistic forging.

Note! With the help of an umbrella, you can solve one of the problems of dampness in the house or bath. If the chimney is open to all winds and rains, moisture that gets into it penetrates into the premises. As a result, the walls and floors are affected by fungus, and an unpleasant odor appears in the air.

Some types of hoods are designed to create a rarefied environment in the upper part of the pipe. Due to this, an improvement in the draft in the chimney is achieved, excess moisture, exhaust air and combustion products are removed faster.

There are several traditional ways installation of wall and island ventilation hoods, which are designed to remove heat, smoke, moisture, odors from technological equipment installed in catering establishments, cafes, bars and restaurants.

The first method of installing an exhaust hood

The first way (the easiest one) is installation of exhaust hoods to the wall using anchors... Depending on the length of the hood, two or three holes are drilled symmetrically in the rear vertical wall of the hood. Through the enlarged washers with anchors, the exhaust hood is attracted and fixed to the wall. The wall in this case must be solid and even, at least brickwork... If the umbrella has a long overhang (more than 1000 mm), it is recommended to additionally fasten the umbrella to the ceiling.

Second installation method

The second way is editing wall or island exhaust hoods through pins and collets to the ceiling... In the upper horizontal plane, along the edges of the exhaust hood, four holes are drilled or special ears are welded under the studs, which include four studs Ф8 - Ф10 mm, previously fixed in the ceiling. The method is quite simple and effective. The only disadvantage of this method is that the ceiling height should not exceed 4350 mm, since the increased height will not allow the use of standard studs up to 2 meters long.

Installation of suction hoods on cables or chains

The third way is installation of exhaust hoods on ropes or chains, through brackets and anchors to the ceiling. In the upper horizontal plane of the umbrella, four special fastening brackets are welded into which a cable or chain is fixed through a carabiner, the other end of the chain is fixed to the ceiling. In this case, the height of the ceilings is not very important. Main possible problem when installing exhaust hoods in this way, it is associated with the instability of the structure. It is rather difficult to tie a rigidly unfixed structure with air ducts.

Installation of an exhaust hood with special support frames

The fourth way is installation of hoods using special support frames. Depending on the overall dimensions of the lower section of the exhaust hood, a support frame is made on which the exhaust hood is installed on top. It can be rectangular or square on four legs, the height of which is selected individually for each object. The legs are rigidly attached to the floor through special support plates. Support frames are made of stainless steel profile 30x30 or 20x40 mm. Thanks to the proven technology, the use of modern metal-working and metal-cutting tools, the specialists of the "EuroVentGroup" company achieve the ideal geometry and very presentable appearance the exhaust hoods produced by the company and the supporting structures required for the installation of these exhaust hoods. In such cases, where the technological equipment is located far from the walls, the height of the ceilings is quite large, and the customer makes increased aesthetic requirements for the arrangement of the local exhaust ventilation the use of exhaust hoods complete with support frames from the EuroVentGroup company remains the only correct solution.

In any kitchen, there is a problem with odors that occur during cooking. This smell can spread throughout the apartment, which is not always pleasant. And during cooking, drops of fat and oil can fly off from food and food. How to get rid of such problems? There is a way out of this situation, and it is quite simple - to install an exhaust kitchen umbrella. It will get rid of both odors and volatile substances.

What is a hood umbrella?

This is a device installed directly in the place where food is being prepared, that is, next to the stove. It removes hot steam and air from the kitchen, as well as odors and impurities. Exhaust hoods should correspond to the dimensions of the plate or be slightly larger than it, but not less. Such a device can be installed in the kitchen an ordinary apartment and even in large canteens. In this case, it all depends on the size of the hood and its type.

Basic types

Such a device for air purification can be of 2 types: an exhaust umbrella and a supply and exhaust umbrella. The first option is used for filtering from grease and dust, as well as for removing air from the room. It does not allow fat particles to enter the general system; they accumulate in a special receiver with filters installed in it. That is why the device, or rather the receiver, needs regular manual cleaning.

The second type of hood performs the same functions - it removes air from the room and cleans it of various elements. But the main difference from the previous type is that in the exhaust hoods with a supply system, another additional function is performed - it pumps fresh air into the kitchen.

Hood material

Both types of hoods are most often made of durable stainless steel. It allows the system to work for a long time without suffering from constant humidity. Caring for such material is easy and simple.

Kitchen hoods are cleaned by filters installed in them, which are also often made of steel material. This simplifies the maintenance and cleaning of the equipment. The food steel used in this case has the highest strength indicators, meeting all quality standards.

Some models use special types of stainless steel. They can easily withstand exposure chemical substances of different origins, including acids. But mainly systems made of such steel are installed in production. In addition to steel, other, less durable materials such as aluminum or glass can be used for the production of an exhaust hood. Although such models are a rare phenomenon.

Varieties of kitchen umbrellas

Exhaust kitchen umbrellas are divided not only by type, but also by varieties, depending on the method of placement:

1. Flat.
2. Embedded.
3. Dome.

Flat exhaust hood

The flat hood is the most economical. It does not have an outlet to the air duct and works according to the circular principle. This system, when compared with other analogs, works quite noisy. Also in the flat hood there is a filter that needs to be changed or cleaned regularly.

Built-in extractor hood

Unlike flat devices built-in models of exhaust hoods are much quieter. A built-in hood is installed directly above the working surface of the hob. In addition to the circular mode, the built-in devices provide for operation in the tap mode.

The last type is domed exhaust umbrellas. They are most in demand and popular among housewives. They can be fixed by various methods to the wall or to the ceiling. That is, they are divided into 2 subtypes: domed and wall-mounted. They work in circular mode and in the air extraction mode, just like the previous models of exhaust hoods. This type of kitchen umbrellas has high performance and the degree of air purification of an apartment or house from odors and impurities.

At what height should the hood be mounted?

From what distance from hob the kitchen hood is fixed, the quality of its work depends. So, for example, if a gas-powered stove is installed in the kitchen, then the optimal height for installing the hood will be about 80 cm.If the stove is electric, then exhaust umbrellas should be mounted at a height of about 60 cm.More detailed information on specific models can be found during purchasing them from consultants. It can also be found in the instructions supplied with the hood.

Exhaust hood filters

The main element required for the full operation of the hoods is a filter. It is with its help that the air is purified. It can be single layer or multi layer, disposable and reusable. Basically, 2 types of filters are used to clean the air in the kitchen: grease filters and spark-suppressing nets.

Grease labyrinth filters are designed to trap fat elements in the air. Spark suppression screens are used in filters if the kitchen hood is installed in the immediate vicinity of the fire source, directly above the stove. If the filter is reusable, it can be cleaned if it gets dirty with plain water, and after that the hood will be ready for use again.

Beneficial features

Any model of an exhaust hood has a number of positive characteristics, including:

1. Moisture resistance.
2. Durability.
3. Resistant to any kind of dirt.
4. Easy to care for.
5. Resistance to mechanical damage.

This is primarily due to the fact that most models of hoods are made of stainless steel. It is easy to clean because it is not afraid of water and has high strength. And filters are made from the same material.

But how to install hoods? It is best to invite a specialist to correctly install the exhaust hood. But in some cases, the installation can be done independently. The main thing is to correctly determine the most suitable place for the hood, and the rest depends only on personal skills.
