Hood for gas stove umbrella. Ways of mounting exhaust hoods from the company "EuroVentGroup. Mounting the hood with special support frames

14.03.2020

A necessary element of any serious kitchen is an exhaust hood. Such a device is mandatory installed in industrial enterprises, but it also has a worthy place in household kitchens.

This extractor variant is exceptionally effective at removing cooking-related contaminants from the air. Let's take a look at the features of the operation of this exhaust equipment and the points that you need to pay attention to when choosing a hood for the kitchen.

A device of this type is a powerful hood designed for efficient air ventilation in the kitchen. They are usually installed directly above hobs in restaurants, cafes, canteens and other catering establishments.

Such a device can be installed not only over conventional cookers, but also over other similar equipment: grill, oven, etc.

The quality of the dishes from the presence of a good hood will only benefit. Umbrellas trap water vapor, particles of oil and fat, remove odors from cooked dishes. All these contaminants rise up under the influence of hot air and enter the working cavity of the ventilation hood. Here, polluted air passes through the filtration system, where it is cleaned.

Hood - stylish and modern device, which will provide effective cleaning air in a domestic or industrial kitchen

Then the air masses, freed from unnecessary inclusions, return to the kitchen or are removed through the ventilation duct, depending on the type of device.

Fatty contaminants move through a separate channel and are collected from storage cups, from which they are periodically removed.

Grease traps are special aluminum elements that are installed inside exhaust hoods. They trap particles of grease and other relatively large contaminants.

To facilitate the process of cleaning the drives from fat deposits, it is recommended to pre-fill the glasses with a special detergent that can effectively dissolve fat.

The advantages of exhaust structures such as "umbrella" include the following points:

the ability to use remote control;
high degree of automation;
possibility of installation suitable model almost anywhere in the kitchen
a wide range of different models made from various materials with an attractive design;
high level of performance.

Among the shortcomings of such equipment, first of all, increased noise generation caused by the operation of a powerful fan is noted. For correct operation the unit should be serviced regularly, i.e. purchase and timely replace carbon filters.

These items cannot be cleaned or refurbished, so the cost of operating the instrument may be higher than expected. In addition, good equipment of this type is quite expensive in itself.

An island umbrella can be installed right in the middle of the kitchen, if the size of the room allows. AT small room such a device can be placed above the stove installed by the window

Extraction equipment in the kitchen is always necessary. Particles of grease, hot steam, soot, drops and other contaminants may not be noticeable at first glance, but over time they form a layer of dirt on various surfaces that is not easy to remove.

In addition, gas residues that can enter the kitchen air and the smell of accidentally burnt food are not good for the health of others.

According to the device, the ventilation umbrella is a steel dome-shaped case, inside of which there is a fan and a set of filtration elements. To collect relatively large particles, a special aluminum grate is designed to protect the ventilation turbine.

In catering establishments, powerful exhaust hoods are mandatory for use over cooking surfaces. Similar devices are used to remove harmful fumes in other industrial productions.

An acrylic filter is usually used to remove a significant proportion of greasy contaminants. In installations with recirculation, it is mandatory to use a carbon filter, which performs fine air purification. Spark arresting mesh protects the elements from overheating and possible ignition.

It is especially necessary if the umbrella is installed above the appliance with an open flame. All filter elements must be cleaned or replaced periodically. Charcoal filters are replaced as soon as they become dirty; these elements cannot be restored.

Some types of acrylic filters can be washed and reinstalled, but this treatment quickly loses its shape, so the number of cleaning and recycling cycles is limited.

The exhaust hood must be large enough to cover the parameters of the cooking surface being processed by at least 100 mm

A fan or ventilation turbine built into the umbrella ensures air circulation in the right direction with the required intensity. The performance of this element provides the total power of the hood, which should be correlated with the total volume of the room in which it will be installed.

A very part of the umbrellas-hoods are equipped with lighting, which is very convenient. Such lamps can be used as additional lighting for the kitchen. Along with conventional incandescent lamps, halogen or diode lighting fixtures are built into the hoods.

The latter provide a sufficient level of illumination with minimal consumption of electrical energy and increased service life.

At industrial catering establishments, exhaust hoods are installed above devices different type: stoves, grills, ovens, etc.

If the umbrella is connected to the ventilation duct of the house, it must be equipped with special valves that prevent the air masses entering the device from returning to the kitchen.

Types of structures and the problem of choice

According to the type of construction, wall and island exhaust hoods are distinguished. The design can be exhaust or supply and exhaust. In the first case, the device only removes the exhaust air from the room, in the second case it also provides an additional influx of fresh air masses.

When choosing a suitable umbrella, consider the required level of air exchange, the size of the cooking equipment, as well as the intended location for its placement. For an industrial kitchen, it is recommended to install a model whose dimensions are 100 mm larger than the dimensions of the hob.

For the manufacture of such devices, food-grade stainless steel is used. The device is usually equipped not only with a grease trap, but also carbon filter. Backlighting can be a useful option. Supply exhaust devices, as the name implies, provide not only the removal and purification of polluted kitchen air, but also the influx of fresh air masses from the street.

Such umbrellas are rarely used at home, this is a technique for professional use. Some transactions require a constant income fresh air. Umbrellas of this type allow creating an exceptionally favorable microclimate in the working room, adjusting the humidity and air temperature to an acceptable level.

The power of the exhaust element usually exceeds the supply air capacity in models of this type by about one third.

The advantage of using a hood is that it can be installed in almost any suitable place, you just need to choose the right model

Wall umbrellas are fixed not on the ceiling, but on the wall. Typically, such models are used to connect to the exhaust duct. To relieve installation work, the hob is installed as close as possible to the ventilation duct.

In this case, it will not be too long, which contributes to the efficient movement of exhaust air into the ventilation duct.

Wall-mounted exhaust hoods can be mounted on the wall. They are more convenient to connect to the ventilation duct of the building than island models.

The short design usually does not need to create many turns when using rigid plastic ducts. There should be no more than three such knees for one ventilation umbrella. The beveled type of island umbrella is very popular, which allows you to bring the hood to the maximum allowable distance from the hob.

An island-type umbrella, which is attached to the ceiling, is considered universal. As the name implies, it is used for mounting over kitchen island, specifically - above the stove built into it. The design feature is that during its installation there is no need to use a wall, the structure is attached to the ceiling.

Such devices are usually used in large kitchens, both industrial and domestic. In small areas, the use of a kitchen umbrella over the island is usually not used due to lack of free space. But such a design may be appropriate even in a small kitchen if the hob is installed near the window.

The presence of two filters allows you to clean the air at a sufficiently high level so that you can return it to the kitchen. Of course you should use necessary funds to ensure sufficient air exchange, but recirculation allows you to save in the room part of the heat energy that was spent on cooking.

To remove polluted air using an exhaust hood, it must be connected to the ventilation duct. If this is not possible, models with circulation and carbon filter are used.

Recirculation is used in island hoods, since it is usually quite difficult to install such a unit next to a ventilation hatch. Read about how recirculation hoods work. Some models of island umbrellas can be adjusted in height, which allows you to change the intensity of absorption of polluted vapors depending on the situation.

If the place for installing the hood is chosen in such a way that the filtered air cannot be discharged into the ventilation duct, then a device with recirculation will definitely have to be preferred.

When choosing an exhaust hood for the kitchen, you should choose the right one. Most Powerful option is suitable for kitchens up to 25 sq. m.

However, you should not choose a model with too much power, because the higher the performance, the more noise the hood makes during operation. For a small room, this can be a real disaster.

Distinguish exhaust and forced-air and exhaust umbrellas. The latter not only ensure the removal of polluted air, but also allow the influx of masses from the street to improve the atmosphere in the room.

The noise level of the device in the region of 40 dB is considered acceptable. It may be slightly higher (up to 70 dB), but you should not choose an excessively noisy model, since the sound of its operation can be annoying. When choosing the type of control, the installation height of the device should be taken into account. If the hood is installed high enough, the remote option can be very handy.

This technique has a high price, so when choosing a brand, you should pay attention not only to the well-known name, but also to guarantee period, as well as for the presence service centers and terms of warranty service. Of course, the design of the device also plays an important role. Fortunately, models of exhaust hoods are very diverse, you can always find a suitable option.

Features of installation and operation

It is relatively easy to install this type of exhaust equipment, but it is still better for inexperienced craftsmen to entrust these operations to professionals. If it is decided to carry out the installation yourself, then you should start with a detailed study of the manufacturer's instructions.

Hoods are usually made from durable food grade aluminum steel. For industrial enterprises such designs are often custom-made

After that, you need to examine the installation site, take the necessary measurements, prepare tools, fasteners, materials, etc. Important point- the correct distance from the hob. It must be at least 60 cm for electric stoves and 70 cm for gas appliances, but not more than 85 cm.

If the umbrella needs to be hung higher, then a more efficient device should be chosen to compensate for the difference in height. To install an exhaust hood, you will need tools that are usually in the arsenal of any experienced craftsman: a tape measure and building level for marking a screwdriver, drill, hammer, etc.

Depending on the type of device, you will either need to simply hang it above the stove, or connect it with an air duct to the ventilation duct. Either a metal corrugated sleeve or rigid plastic structures are used as an air duct.

The corrugation can be bent in a suitable way, and to make a plastic elbow, special adapters should be used to ensure a tight connection of individual sections of the duct.

If the power cord is not long enough, you need to install an additional outlet near the device. You need to make sure that the appliance has the necessary grounding.

Proper installation of the ventilation hood is only half the battle. In order for the device to work effectively, it is necessary to organize its work. Detailed information on such matters is contained in the instruction manual supplied with each instrument.

Regular cleaning is of great importance. For example, aluminum grilles should be washed with special detergents. The use of products that can be found in any kitchen also gives a good result: acetic acid, diluted by a third with water, a saturated solution of ordinary laundry soap, or a pasty mixture of water and baking soda.

The aluminum grate traps of exhaust hoods should be regularly cleaned of dirt accumulated on them in order for the device to work correctly and efficiently.

These recipes are useful for those who suffer from intolerance to chemicals. Grids should be cleaned from accumulations of grease and dirt at least once every three months.

Charcoal filters are usually replaced in the following order:

disconnecting the device from the power supply;
dismantling of aluminum gratings;
removing the used filter;
installation of a new filter element;
installation of aluminum gratings;
connecting and checking the operation of the device.

At the time of installing a new filter, a characteristic click should sound. If, after replacing the filter, the hood makes unusual sounds or becomes noisier, the filter may not be installed correctly and the operation should be redone.

If the ventilation hood filters are not cleaned and replaced in a timely manner, the performance of the appliance may deteriorate significantly.

Charcoal filters are necessary in hoods with circulation, they provide fine air purification and need to be replaced regularly

Removable filters and glasses for collecting fat in models of umbrellas that are used in catering establishments, in accordance with the instructions, should be cleaned daily. It is also necessary to constantly clean the outer surface of the housing of the exhaust device. Some elements are recommended to be removed and soaked in special cleaning solutions.

After cleaning, they are thoroughly rinsed. Another element that needs periodic cleaning is the air duct. It is necessary to remove the connecting elements and remove deposits from the inner surface of the structure.

Corrugated elements often need such cleaning than smooth plastic channels. Some industrial models of kitchen umbrellas are equipped with a built-in cleaning system, but such expensive units are usually not used in everyday life.

Conclusions and useful video on the topic

This video shows the principle of operation of such structures:

An exhaust hood can ensure proper air exchange in both conventional and industrial kitchens. Correct installation and regular care will ensure long and trouble-free operation of such a device.

The root of construction troubles is hidden in the details. Neglecting small details, the owner of private housing inflates the family budget inefficiently with repair costs. But if the owner treats the house as a whole organism in which everything is interconnected, his money does not fly into the pipe, and the costs are limited to scheduled maintenance. Wrong installation protective devices on the chimney provokes losses - both financial and human.

Installing an umbrella on the chimney contributes to the maintenance of work heating system optimally, to prevent premature aging chimney, improve air circulation in the house.

Caps and caps on pipes are designed for the following purposes:

close the ventilation duct, protecting it from rain, snow and dirt. Lack of protection can lead to accumulation a large number water in the chimney, which contributes to a decrease in traction and, accordingly, a drop in the efficiency of the heating system;
protect the pipe material from damage, removing 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. Give the roof a complete appearance, especially if the design contains elements of artistic forging.

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

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

In any kitchen there is a problem with odors that arise 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 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 hood. It will get rid of both odors and volatile substances.

What is a hood umbrella?

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

Main types

Such an air purification device can be of 2 types: exhaust hood and supply and exhaust hood. The first option is used to filter grease and dust, as well as to remove 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 purifies it from various elements. But the main difference from the previous type is that in hoods with supply system one more additional function is performed - it pumps fresh air into the kitchen.

Material for the manufacture of hoods

Both types of hoods are most often made of durable stainless steel. It allows the system to work for a long time and at the same time not suffer from constant humidity. Care of such material is easy and simple.

Exhaust hoods for the kitchen are cleaned by the filters installed in them, which are also often made of steel material. This simplifies maintenance and cleaning of the equipment. Food steel, which is 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 the effects of chemicals of various origins, including acids. But basically, systems made of such steel are installed in production. In addition to steel, another, less durable material, such as aluminum or glass, can also be used to produce an exhaust hood. Although such models are rare.

Varieties of kitchen umbrellas

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

Flat.
Embedded.
Dome.

Flat hood

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

Built-in 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, embedded devices provide operation in the tap mode.

The last type is domed exhaust hoods. They are most in demand and popular among housewives. They can be mounted in various ways to the wall or to the ceiling. That is, they are divided into 2 subtypes: dome and wall. They work in circular mode and in air exhaust mode, as well as previous models of exhaust hoods. This type of kitchen umbrella has high power and degree of purification of the air of an apartment or house from odors and impurities.

At what height should the hood be mounted?

From how far from hob a kitchen exhaust hood is fixed, the quality of its work depends. So, for example, if a gas stove is installed in the kitchen, then optimal height to install the hood will be approximately 80 cm. If the stove is electric, then the exhaust hoods should be mounted to a height of about 60 cm. More detailed information on specific models can be obtained from consultants at the time of purchase. It can also be found in the instructions from the kit for the hood.

Hood filters

The main element necessary for the full operation of exhaust 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 those with spark arresting nets.

Grease trapping labyrinth filters are designed to retain elements of grease contained in the air. Spark arresting screens in filters are used if the kitchen hood is installed in the immediate vicinity of the fire source, directly above the stove. If the filter is reusable, then it can be cleaned when contaminated with ordinary 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:

Moisture resistance.
Durability.
Resistant to all types of dirt.
Ease of maintenance.
Resistance to mechanical damage.

This is primarily due to the fact that most models of exhaust hoods are made of stainless steel. It is easy to wash, because it is not afraid of exposure to water and has high strength. Filters are made from the same material.

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

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

In this article we will talk about the use of exhaust 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 purify 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 integral part high-quality ventilation system in the premises. Installation takes place above sources of high temperature, in particular, over stoves, hobs, open flames. The dome removes wet hot air, unpleasant odors, as well as soot, grease, soot, dust, chemicals.

Air purification from harmful impurities also necessary in laboratories, chemical and industrial production, etc., where manufacturing process occurs with the release of harmful substances into the space, which can harm workers and environment generally.

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

Installation of wall-mounted units is carried out directly on the wall. With a large weight, additional brackets are used for fixing. Central devices are installed directly above the work surface, without contact with the walls. Island umbrellas have a large capacity.

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

There is no fundamental difference in structure between domestic ventilation domes used in private households and industrial ones, they are distinguished only by size and power characteristics. Umbrellas used indoors have a common device:

Grease filter. It can be mesh (made from a grid 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 arresting mesh, but it requires frequent cleaning. The labyrinth grease trap can only be installed in an inclined position and does not require frequent washing.
Sparkling mesh. An obligatory element when installing ventilation domes over sources of open fire, for example, over barbecues, grills.
Pendants. Part of the mounting system that allows you to mount an umbrella on a wall or ceiling with the correct weight distribution.
Turbines. The equipment is designed to stimulate the movement of air masses from the room. During installation, the center of the work surface and the dome must be correctly determined in order to achieve maximum efficiency. The cross section of the inlet of the exhaust hood must exceed the dimensions of the slab or other equipment over which it is suspended. The suspension height varies from 0.7 to 1.1 meters.

When choosing a manufacturer of an exhaust dome, 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 he built himself a small workshop, which at the same time also serves as a pantry for tools and inventory. Everything seems to be fine, but warm days have come, periodically turning into heat. And about natural ventilation I forgot. But we'll fix this. There are many options, one of them I will describe in this article.

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

The umbrella should be installed in such a way that on the back of the roof, that is, from the inside of the room, the vent does not block anything: neither rafters, nor struts, nor lamps. If you do not understand how it works, here is a description. Measurement is best done from the skate. They immediately estimated the size from the inside, after which they transferred it to the outer slope of the roof. At the measured point, we drill a hole in order to insert the canvas cutting tool.

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

Given that roofing consists of shingles, laid on an OSB-plate, which, in turn, is mounted on a continuous crate from a board, it is almost impossible to cut a hole with an electric jigsaw - the saw will not run enough, and if it does, then it is very close and there is a chance to bend it thoroughly. Since the hole has round section, neither a circular saw, nor even a chainsaw can make an even hole in size. Therefore, as a cutting tool, I chose a reciprocating electric saw. Very convenient and fast, the main thing is not to rush.

The hole is ready, you can proceed to install the ventilation umbrella. In order for the mounted wind vane to not have a powerful wind blower and the wind not to hum in the empty pipe for solo parts, it has an unusual shape. Its upper part is covered with a lid, curved on four sides, so that one large opening is divided into four compartments. Warm air it will leave the room through all four holes, but it will only blow into one, depending on the direction of the wind. We install a segment of the duct from the inside and put on an umbrella from above.

To eliminate the possibility of rain moisture getting on the metal structures of the ventilation hood, you need to carefully lift the roofing and shove the protruding support elements of the hood under it.

This operation should be performed 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 roofing.

The fact is that if you run the lower part under the roofing, then when it rains, water will accumulate in the resulting barrier, and no matter how well you seal it, the 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 I have a ventilation umbrella installed in the utility room, I decided to fix it on ordinary nails. In addition, the umbrella will be subjected to wind pressure, and an ordinary nail is inherently nog, that is, it has a small up and down stroke, and in the case strong wind the probability that the nail will cut off the hat is almost zero, which cannot be said about self-tapping screws.

The last in numbering, but not least, is the sealing of "weak" places. These are, as a rule, joints, junctions of one structure to another, and places for installing fasteners. The sealant must be selected special: heat-resistant or heat-resistant. In the summer heat, the roof is heated so that, if desired, you can fry the scrambled eggs, so the sealant must endure such a temperature load. We evenly apply sealant around the entire perimeter of relatively weak spots.

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