Kitchen hoods with connection to ventilation: a review, the principle of operation, prices. Connecting the cooker hood to the ventilation

Kitchen hoods with connection to ventilation and without it play in the kitchen not only the role of the output of vapors and flavors for the purposes of environmental safety. They also prevent the damage of surfaces. Various fumes, combustion products of fuel and residues of fat in the air gradually accumulate on walls, working surfaces, ceiling and floor. Due to this effect, they begin to fade, deteriorate from fat and other deposits. With the use of hoods, these processes can be minimized, which saves your finances and prolongs the life of kitchen implements.

Types of flow hoods

Models and varieties of devices under consideration differ in size, design, price, principle of operation. Kitchen hoods with connection to ventilation are used to maximize the removal of air from the space above the working kitchen surface and its subsequent deactivation into ventilation through the air duct.

The aggregates under consideration are divided into two types:

1. Passive models. The design does not provide for the installation of an electric motor. The whole work process is due to the draft of the ventilation duct system.
2. Active kitchen hoods with connection to ventilation function due to the additional connection of electric motors, which are located inside the dome. Motors provide a powerful airflow, grasping soot, soot, droplets of fat.

Furnishing

Any type of flow-through exhaust design is mounted directly above the plate. With ventilation shafts, the unit is connected by special vozuchovodami. This can be a tin box or a metal corrugation. To prevent unwanted noise, air ducts are equipped with soundproofing material. Aesthetic appearance they do not spoil if you disguise the device behind the suspended ceilings.

At the neck of the main device, the air ducts are fixed with clamps. In addition to the elements considered, the hoods include the following accessories:

• Coarse filter. It protects the devices themselves from the build-up of grease and soot.
• Thin filter. It serves to remove odor. It consists, as a rule, of coal elements.

Timely replacement and cleaning of filters will not only improve the efficiency of the hood, but also extend the life of the unit itself.

Extractor without duct

Such a device operates recirculatingly and does not require connection to ventilation ducts. Air with a fan is sucked into the filtration unit, where it is cleansed of odors, burnt, excess moisture and fat. The efficiency of the device depends on its capacity and filtration system. Kitchen hoods without connection to ventilation are equipped with two main filter units.

The first system serves to eliminate fat storage in the air, and also provides a rough cleaning. These elements are made of aluminum or acrylic. The first option is more effective because it lasts longer and is easy to clean.

The following system struggles with unpleasant odors, excessive moisture, burning residues. The main element is a carbon filter. It requires regular replacement (approximately once a quarter).

Types of cooker hoods without connection to ventilation

All considered devices operate on the same principle, but differ in the type of installation, namely:

1. Classic version in the form of a flat umbrella. Has no special design refinements. I recommended myself as a good hood for small kitchens.
2. Suspension model. It is installed above the stove, the air flow is ejected from the front part, which makes it possible to fasten the lockers on it.
3. Built-in version. Allows you to hide the device inside the furniture. The device is compact and has high power ratings.
4. Kitchen hoods without connecting to ventilation with telescopic equipment. These varieties can be moved closer to the work surface as needed.

The units under consideration perform various functional tasks, depending on where they will be mounted (in the middle, in the corner or in a separate way).

Advantages and disadvantages of hoods without air ducts

Kitchen and any other equipment have their minuses and pluses. The exhaust device without connection to the ventilation system has a number of advantages:

• Elementary installation, which does not require the use of additional fittings and connecting hoses. The device itself can be installed easily.
• Economical. Given that even kitchen hoods (60) with connection to ventilation use an order of magnitude more energy, this modification can rightly be called economically profitable.
• The cost of the construction in question is lower than that of a similar system with a duct.

The downside of such aggregates is the need for regular replacement of filter elements. This will have to be done at least once a quarter. Kitchen hoods without connecting to ventilation, the prices of which start from 5 thousand rubles, will become a reliable assistant in your kitchen.

How to connect the hood without a duct?

Devices operating in recirculation mode are easier to install than kitchen hoods with connection to ventilation. This is due to the fact that they do not require interaction with the ventilation shaft. In these devices the main thing is to change the filter elements regularly.

Beforehand, it is necessary to take care that there is power supply near the installation site of the hood . Before installing the unit, mark the fixing points, drill holes, install dowels or screws to fix the device. The next stage will be fixing the hood on the wall, connecting it to the outlet and a test check.

Installation of the unit with air duct

By and large, connecting the kitchen hood to the ventilation of special problems will not be. The main thing is that all connections are tight and securely fixed. Doing the work, you need to consider the following recommendations:

• The connection must not completely cover the ventilation duct, so that when the device is switched off, natural draft of air is carried out.
• Normal operation of the unit will ensure the passage of airflow without additional interference.
• The length of the duct and the number of curls should be kept to a minimum.
• Choosing between the corrugated and smooth pipe surfaces, it should be borne in mind that the first variant flexes well, but delays flow.
• On the bends, the duct must have smooth transitions.
• Additional airflow after airing or constant feed from the street will make the hood more efficient.
• It is forbidden to mount the device with outlet to the smoke channel of the gas column.

The way how to connect the hood to the ventilation yourself, is not particularly difficult, subject to certain nuances and technological subtleties.

Conclusion

Having studied the features of the device, the principle of operation, the nuances of operation and installation, we can conclude that the hood must certainly be present in the kitchen. The choice of modification depends on the size of the room, the intensity of the workflow, financial capacity and own preferences.

The connection of the extractor to the ventilation, the principle of operation of which is based on the intake of the airflow and its subsequent transportation to the ventilation shafts, is more complicated and requires certain calculations. For example, excessively long ducts will look unaesthetic and reduce the efficiency of the device itself. At observance of certain moments the assembly works are very simple and understandable.

The option without ductwork in the installation is much simpler, and its price is lower. However, there are some peculiarities here. It will be necessary to regularly replace the filter elements, otherwise the efficiency of the hood will be significantly reduced. Devices without interaction with ventilation have several types of fastening, which allows them to be selected for any size and interior of the room.
