Each owner wants to create the most modern and comfortable conditions in his kitchen. During the cooking process, warm air currents create unpleasant atmospheric indicators. To avoid this, you need to mount the hood with the air duct in this room. Thus, the outflow of odors will occur.
The hood has its own design features and the constituent elements. Each model has a common task and principle of operation. An important element is the exhaust duct. It helps flows out of the kitchen. According to external data, this is a kind of pipe through which the vapors are collected and sent out.
Masters argue that if you do not mount the exhaust duct in the kitchen, such a system will not benefit. Although there are units on sale that can do without it. Just inside are placed special powerful filters. But today they have not gained popularity, as they often have to change the internal installation.
Functions
In the house or apartment where people live, there are standards by which you need to organize a suitable microclimate. For this reason, it is necessary to create conditions in which ventilation of air flows will take place. And to do this without the necessary units will not work. But this system will not cope with burning and fumes in cooking. Because in this design, metabolic processes occur naturally.
In the kitchen, the unit should be placed where streams of unpleasant odors most often accumulate. Many place them over a gas stove. You will have to purchase a unit that has an air duct for drawing.
What is suitable for the kitchen?
Air injection can occur using several types. They are divided:
- In shape.
- The material from which they are created.
- By external indicators.
Therefore, before you go shopping, you should decide for yourself what is required. Intensity of cooking, features of the kitchen itself, etc. are taken into account. It should be understood, at least in theory, that each of the forms carries in itself.
Duct shape
Here there is a bias precisely in the section. The stores have the following options:
- Rectangular They can be placed anywhere, even behind furniture. They are sold as separate designs with adapters. This addition allows you to easily lay out the passage for air flows in the ventilation shaft. At the same time, the dimensions of the kitchen themselves do not affect the unit. External data is quite acceptable, so it is not necessary to mount the design behind the cabinets. But performance is not too high.
- Round shape. They are large in size, so this model will not be appropriate for everyone. Sometimes, in order to connect the part with the main hood, you have to purchase an adapter from a round section. So before buying it is worth considering every moment.
- Oval shape. Here the main advantage is in round shapes. Therefore, the decision is up to the owner.
Often they choose exactly flat designs, for their compactness. The design can be carefully removed from the eyes. There are some models in stores:
- 110 by 55 millimeters. This is the minimum load and the ability to remove air flows from a room up to 300 cubic meters per hour.
- 120 by 30 millimeters. Here it is already possible to expel a large amount of air, but not more than 350 cubic meters per hour.
- 206 by 60 millimeters. This is the maximum size. Such structures are already being installed at large enterprises when it is required to distill large flows of air.
It turns out that you need to choose the right duct for the hood. When a decision is made about what functions the unit should perform, it is worth considering which material it is best suited for.
Materials
To create a good design, various materials can be used. Here is what a duct can be for hoods in a kitchen:
Plastic
This material is by far the most common and common. Available section - round and rectangular. The first plastic ducts for the kitchen hood help you complete the installation quickly and without additional difficulties. But rectangular ones look better in appearance. Here are the main advantages of plastic ducts for hoods that give out reviews:
- Inside the full surface, which allows dirt and grease not to linger. It is this unit that will be most useful for every kitchen.
- Plastic does not rust - this is a big plus.
- Light weight, so everyone can mount the design.
- In the assembly of the plastic duct for the kitchen hood, different adapters are used. This means that everyone can assemble a structure of any size.
- The plastic duct for the hood does not generate noise during operation. This is a big plus for a multi-storey building.
- Low cost.
Minuses
It is clear that with any pluses, there are also minor disadvantages. What you should know about:
- To assemble the structure, you will need many additional parts and adapters. For this, the cost of the final result increases.
- React to high temperature. And when heated, chemical fumes can be released into the air, this is not suitable for people.
Aluminum aggregates
Such material is often used for its reliability. Corrugated pipes are made from it. Reviews say that such designs have their positive aspects:
- The material is universal and is used in many directions. The result is a lightweight and easy to install design.
- It reacts calmly to heat.
- Low price.
When there are many advantages, this does not mean that cons are completely excluded:
- According to external data, few people are satisfied with such pipes. Therefore, most often they are cleaned in specially mounted boxes or installed in a cabinet. Such conditions are not suitable for everyone, but it turns out ugly in a different way.
- With physical exposure, gaps appear. Deformation is often observed. It is necessary to carry out a neat installation.
- Aluminum is considered a metal that conducts heat. As a result, condensation forms in the kitchen because of this, and this contributes to the development of mold.
Having such information, a person must decide for himself whether such a duct is suitable for him or not. Since to create boxes you will need a place in the kitchen, but it is always small. In addition, do not forget that condensate must be removed. Otherwise, the formation of mold and fungus is not excluded.
Steel material
Most often galvanized or stainless steel is used. This material brings more effect. In the kitchen, air ducts are made of galvanized steel. According to statistics, people are increasingly acquiring aggregates from such a composition. Although the advantages are enough:
- A big plus in a flat surface. As a result, any air flows pass quickly. The kitchen always has grease, soot and other impurities. They do not stay on the walls. Moreover, the air flow rate during operation does not decrease.
- When heated, there is no deformation or destruction. In this case, nothing harmful is released into the environment.
- This is an inexpensive option for people with average incomes.
At the same time, reviews note the following disadvantages:
- Compared with plastic, the weight of the steel structure will be large, which means that during installation it will be necessary to build quality support.
- To make the sealing maximum and reliable, you will have to use additional mixtures. They are applied to each seam.
- When you have to collect non-standard air ducts, you need to cut pipes, and this is additional equipment during installation.
- Since this is metal, it may make noise during the operation of the hood.
The service life of such pipes is high, so sometimes, having spent a little more time on installation, you can get a reliable design. Some people think that when the steel is put into the box, the noise starts to go out. This is a big plus. In any case, the decision is made by a person from his personal desires and financial capabilities.
These are the basic materials from which create ducts for the kitchen hood. These models are always on sale. It is clear that before you purchase any of the options, you need to think through the entire design. Because not every kitchen can accommodate boxes.
What are the external data of the unit?
It is clear that a hood without a duct in the kitchen cannot exist. The configuration can be any. One popular option is flexible designs. This is a corrugated pipe, aluminum, but today we have already learned how to make such structures out of plastic. The big advantage is that they can take any shape and go around every corner. If necessary, the structure can stretch or contract. But when the pipe is not very stretched, the air passes slowly. This means that work is generally not effective. Corrugated pipe is not suitable for an air duct that has a length of more than three meters. The fact is that, due to the design feature, each additional meter reduces the efficiency by more than five percent.
Rigid options are made from solid material. Assembly is simplified. The inner surface is smooth, which means that dirt, grease and other deposits are not collected. And this is the main plus in the operation of the unit in the kitchen. Therefore, the price of such an exhaust duct is slightly higher than that of a flexible design (265 rubles per meter versus 180). When a person begins to apply a rigid structure, the benefits are immediately noticeable. The fact is that a common problem with any hood is clogging. With a rigid duct, blockage is minimal.
How to install?
When the choice is made and the design is acquired, it is worth considering every centimeter to create the right unit. The very first thing is to decide what size the duct will be. In order for the unit to be executed in compliance with all the rules and work at maximum, you need to follow simple recommendations:
- An outlet is made with a specific size. It is necessary to create such a section as that of the unit itself in order to completely exclude large drops. If you select less, then the motor overloads. There is noise, and the work itself becomes ineffective.
- When the outlet does not correspond to the main section, there are adapters to create the most comfortable conditions.
These are small installation features that are worth observing. The installation itself is not as complicated as it might seem at first glance. So that everyone can do it himself. It is important not to violate the rules and recommendations for installation.
What is worth knowing?
When work is being done to install the duct tightly, you need to know some nuances:
- If possible, make as few turns as possible throughout the structure. Because each such element makes the work less efficient and correct. The hood should have no more than two or three knees.
- It has already been noted that the hood should be periodically cleaned. Air duct - including (regardless of what it is made of). It is advisable to make it collapsible.
- If the choice is made in favor of a corrugated aluminum pipe, then it can be fixed with an ordinary clamp, of appropriate diameter.
- During installation, it is not recommended to fix the duct to the ventilation grille tightly. The fact is, if the system is turned off, then air will not flow. To avoid this, you will have to supplement the design with a grill with small slots and a backdraft valve.
- The valve must match the diameter of the exhaust duct. Otherwise, the operation will be disrupted due to the use of the adapter. This should not be forgotten during the purchase process.
- It is believed that a flat duct for the hood is the most accurate and will not spoil the existing interior in the room.
When some installation features are known, it is certainly not difficult to install the entire structure. But before you create good conditions in the kitchen, you need to know how to hide the structure from view.
How to hide the design correctly?
In order not to spoil the view in the kitchen, it is better to remove the duct in the box. There are simple methods for this:
- If there is a suspended ceiling, then all the pipes go well there.
- You can create a special box. It can be any in color and uniform. Sometimes backlighting is built into it, creating a new original element in the interior.
- Sometimes pipes pass inside the cabinet.
Conclusion
Creating a kitchen exhaust system is easy. There are many offers on the market, varying in price and manufacturers. It remains only to choose a suitable design, taking into account personal desires.
