Extracts for the kitchen with a vent to ventilation: principle of operation, diagrams and installation rules
During the cooking process, the kitchen is filled with steam and food smells. All this is absorbed into the walls, headsets and adversely affects the well-being of people in the room. Filling the room with fresh oxygen will help extracts for the kitchen with a vent to ventilation.
They, unlike recirculation models, remove the air from the room, and not just drive it through the filters and return it.
Types and features of exhaust devices
The variety offered by manufacturers of extracts is sometimes amazing. In the market, you can easily find the optimal cost and quality model. But for an unprepared buyer, the choice and installation of such kitchen appliances will become a difficult and sometimes impossible task. Therefore, before you go to the store or install the hood, it is imperative to understand all the subtleties and nuances.
Sanitary standards and requirements
Any type of exhaust, whether it is recirculation or a device with a vent to ventilation, should drive an air volume equal to 10–12 volumes of cooking space in one hour.
This is a strict sanitary requirement that must be met. Indeed, in the kitchen are actively used sources of open fire, heating devices. Yes, and the humidity in the room is much higher than in other rooms. As a result, the concentration of carbon dioxide, harmful impurities and vapors is constantly increasing, which will adversely affect human well-being.
Another requirement is that the hood should be installed as close as possible to the cooking surface. This is at least 65 cm for the electric stove and 75 cm for the gas.
A prerequisite is the presence on the device of a special lattice where dirt and grease will settle. Due to this, the waste will not get into the ventilation duct.
Exhaust hood in the ventilation
Hoods, exhaust air through the ventilation shaft, are the classic and most familiar to most people models. Thanks to the constant influx of fresh air, a person is in a better mood, his health improves, and his stay in the kitchen will become more comfortable.
Typically, exhaust devices provide forced ventilation, which uses a fan. This approach allows in the shortest possible time to remove from the room excess moisture, which can damage the furniture set, unpleasant odors, various fumes, soot, excess carbon dioxide, etc.
In order not to pollute the atmosphere around the house, a special filter is used in the hoods, which collects most of the dirt.
The only drawback of embedded hoods with a vent to ventilation is the complexity of their installation. After all, the device must be connected to the duct. If the house does not have a ventilation duct, then you will have to drill a hole in the wall.
Types of hoods with tap
There are several types of such kitchen appliances. Hoods with exhaust in ventilation are divided into categories depending on the design of the device, method of installation and cleaning.
According to the type of installation, such devices are distinguished:
- Hinged. They are divided into dome or flat. And still on the market are inclined products that, if necessary, can be expanded. Hinged hood harmoniously fit into the large kitchen, and in the room of small size.
- Embedded. Devices of this type are the ideal solution for small apartments. Their peculiarity lies in the fact that they are built into the cabinet and act as its bottom. Some devices can move apart, allowing you to increase the amount of air trapped.
Owners of a large area of kitchens prefer island construction of an exhaust appliance. It is used in situations where the stove is located not in one of the kitchen walls, but in the center of the room. Island hoods are attached directly to the ceiling and allow you to create an original design of the room.
In addition, the device for removal of exhaust air is an important element of the kitchen.It not only absorbs harmful fumes, but also acts as a decorative element. Therefore, choosing one type or another, you need to assess whether the desired model will be in harmony with the design of the kitchen.
Exhaust Selection Criteria
Hood - this is one of the main elements of any modern kitchen. Therefore, its choice should be approached with all responsibility. In order not to miscalculate and buy the optimal device, it is necessary to pay attention to the whole characteristics inherent in these devices.
Among the criteria that influence the choice are the following:
- the size;
- modes of operation;
- type of filter used;
- availability of additional functions;
- case material;
- control method of the device.
Of course, the optimal size is extremely important when choosing a device. It directly depends on the dimensions of the hob. Therefore, before going to the home appliance store, you need to know it.
In order for the exhaust hood with ventilation in ventilation to cope with its main task, its dimensions must necessarily correspond to or be slightly larger than the area of the stove.Due to this, the device will take the maximum amount of vapor from the kitchen, which will significantly increase its efficiency.
With regard to the choice of mode of operation, then you need to decide what kind of device is needed. The fact is that exhaust hoods can work in the modes of recirculation and exhaust of air through the ventilation shaft, or combine two options. The best solution would be to purchase a combined model. If the choice fell on the latest variety, then you need to ask the seller about the cost and availability of filters.
Before you buy, you need to see what filters are used in your favorite hood. They are designed to collect most of the fat and dirt. There are several types of filters. The best solution is metal mesh. They are versatile and easy to clean - they can be easily washed.
As for plates made of synthetic material, this is not the best choice - they can not be washed.Such products will have to be changed regularly, and these are additional costs. After they have served their time will have to go to the store and buy new ones.
Among the additional functions of hoods, the interval mode of its operation is the most useful and practical. She must be in any hood. This means that the device will turn on from time to time, clean the air and then turn off.
In the overwhelming majority of mid-range models, an electronic timer is used to implement this feature. As for the more expensive products, their interval mode is based on the use of sensors analyzing the composition of the air. But such a highlight will significantly increase the cost of the hood. Therefore, before buying to be a good think: is it worth this feature?
All exhaust devices are significantly different material housing. Manufacturers offer kitchen appliances with air exhaust through ventilation made of enamel, tempered glass or stainless steel.
Before choosing a material, you need to remember that durability, appearance and, of course, the cost of the device depend on it. Therefore it is important to consider all the positive and negative sides of each of them.
The main advantage of enameled and metal surfaces is their low cost. In addition, they are easily washed and brushed. In the list of features of models, the body of which is made of stainless steel, you should add their presentable appearance - such devices can not be built into the cabinet.
As for the tempered glass hoods, these models look just gorgeous and cost accordingly. At the same time, to keep them clean, you will need to regularly and carefully take care of them. Yes, and handle this technique should be very careful.
Not always the appearance corresponds to the internal content. This statement applies to kitchen hoods. After all, today it is easy to buy a device with a huge dome, the power of which is not enough to clean the air, even in a small kitchen.
In order not to make a bad choice, it is necessary to calculate in advance the optimum performance of the device. To do this, find out the volume of the kitchen - multiply the floor area by the height of the ceilings.
For comfortable work in the room you need to buy an exhaust hood, which in 5-6 minutes will be able to completely refresh the air in the room. That is, in an hour the device should have time to make 10-12 such cycles. To find out the exhaust capacity required for your kitchen, multiply the volume of the room by the air change rate (10-12).
For example, if you take a small room with an area of 15 m2where the ceiling height is 3 meters, then, multiplying these values, we obtain a volume equal to 45. We multiply this number by the air exchange rate and add 20% as a reserve, we will find out the optimal exhaust power for such a kitchen. In this example, the performance of the device should be equal to 450-540 cubic meters per hour.
Noise device plays an important role - the hostess often spends several hours for cooking, and sometimes half a day.Some even install TVs in the kitchen so as not to miss their favorite movie, series or program.
It is hardly necessary to say that a noisy hood will not allow you to concentrate and will not let you hear what the melodrama heroes are talking about. Therefore, in order to determine the optimal model for yourself, it is necessary to deal with decibels.
The volume of normal human speech is 50-60 dB, while for quiet music this figure does not exceed 40 dB. As for the exhaust, you should see the noise level in its technical passport. It should be in the range of 40-80 dB.
Choosingexhaust device, it is important to pay attention to how to control it. There are three types of buttons - touch, mechanical and combined. The cheapest, most simple and reliable are mechanical models. In this case, the power is adjusted using a series of special buttons or a slider (movable slider).
The touchscreen display only requires an easy touch.Such hoods look modern. The advantage of sensory models lies in the simplicity of their care. Due to the absence of protruding elements, dirt from the display is easily removed with a damp cloth.
Hybrid models, unlike sensory and mechanical, are not so popular. Here, the buttons are fully recessed inside the case, so they can only be felt. But on the other hand, it is as easy to care for hybrid devices as for sensory ones.
When choosing a particular model, you must pay attention to the lighting option. In inexpensive hoods for this, ordinary incandescent bulbs are used. Though they are cheap, they burn out much more often. In this case, such lighting consumes a large amount of electricity.
It is better to give preference to models that use halogen lamps. They are a more economical alternative, and shine much brighter. But note that with such lighting food will take on an unnatural appearance.
The ideal option is the LED lamps. They need a minimum amount of electricity and serve for years.
A distinctive feature of hoods with air exhaust in the luxury ventilation is the presence of motion sensors. Thanks to such a constructive solution, the light is turned on if activity has been noticed in the area of the cooking surface.
In addition to the technical characteristics, it is useful to read the reviews of other buyers about a particular model. Numerous users who have already ordered this or that hood and managed to use it, will point out the advantages and disadvantages of a particular product. This approach will allow you to weigh the pros and cons and get the best hood for your kitchen.
Rules for connecting the hood
To pick up and buy an exhaust hood suitable for your kitchen with air exhaust into the ventilation shaft is only half the battle. It is also important to competently carry out installation of the device.In order not to make mistakes, you must adhere to a specific sequence of actions.
First, immediately after purchase, you need to check the complete set of the device. The box must contain a technical passport with installation instructions, an exhaust device and a set of fasteners (screws and anchors for mounting on a brick wall).
Then it is important to prepare everything for work - building level, punch or drill, tape measure and screwdriver. Further, the order of work will be as follows:
- using a tape measure, measure about 70-80 cm above the cooking surface and use a level to draw a horizontal line;
- In the center of the line drawn earlier draw another, perpendicular to it;
- using masking tape, fasten the template on the wall so that it does not move when drilling;
- then with a drill and a drill that matches the supplied screws, four holes are made in the wall;
- screw the screws into the wall so that their head protrudes 0.5 cm;
- then remove the grill and cover from the hood and hang it on the fasteners;
- now it remains to screw the screws to the end to securely fix the device on the wall.
The installation of the hood ends with the installation of the cover and grille. Next comes the most important and laborious stage - the organization of ventilation. But, in compliance with all the rules and recommendations, this process will not cause absolutely any difficulties.
Selection and installation of ventilation ducts
There are two types of ventilation pipes for exhaust - plastic products and corrugations. The latter variety is in great demand, as it has many advantages.
The advantages of corrugated pipes include:
- Easy installation. The product is made of thin aluminum, so that the corrugation can be bent and rotated as required.
- The ability to quickly change the length. If the pipe is too long, the excess can be cut with ordinary scissors. And when the calculations were carried out incorrectly, the corrugation can be increased without any problems - the elements are quickly and well connected to each other.
- Low weight. The material is very light, so you can save on additional fasteners and reduce the time required for the installation of ventilation.
- Cheap. A buyer with any income level can afford to buy a corrugation.
But at installation of this material it is necessary to be extremely accurate. After all, the corrugation is very malleable and a strong pressing can leave an ugly dent on the product.
As for the plastic ventilation pipes, experts recommend using them. This kind of product has a smooth inner surface, so that the flow will not slow down against the walls and lose its speed. In addition, the material is distinguished by its cheapness, the absence of elements susceptible to oxidation, as well as safety for human life and health.
Where better to place the outlet?
The exhaust in the course of its work consumes a considerable amount of electricity.Therefore, experts recommend to hold a separate line for the device, because otherwise the entire network may not withstand such voltage.
The socket should be located directly next to the device itself. Note that if a gas stove is used for cooking, then the socket must be removed from it to a safe distance.
Terms of care for the hood
That the device served long, it needs to be cleaned regularly. Before washing the hood it is necessary to de-energize. Further, it is necessary to remove the grate or filter and wash all parts of the device on which dirt could accumulate. For cleaning, you can use dishware or a special compound designed for stainless steel products.
A distinctive feature of modern materials is the simplicity of their washing. But sometimes, in the case of strong pollution, you need to use detergent. Please note that it is prohibited to use a powder, metal sponge or sponge with a hard fiber structure for cleaning - they will scratch the surface of the hood.
To wash the buttons using a soft cloth dipped in detergent solution.After all the elements of the hood are perfectly clean, and the surface of the device has been wiped dry, the device can be plugged into a power outlet and its operation can continue.
