Types of kitchen range hoods
1, Chinese range hood
Mainly divided into old-fashioned shallow suction deep range hoods, especially shallow range hoods. That is, the ordinary exhaust fan directly discharges the oil fume to the outside. The biggest problem of deep-suction range hood is that it takes up a lot of space, makes a lot of noise, is easy to touch, can't clean the dripping oil fume, has a short service life, is inconvenient to clean and pollutes the environment. Many brands.
2. European range hood
Use multi-layer oil net to filter 5-7 layers to increase motor power and achieve the best effect. Generally, the power is above 300 watts. Features: beautiful appearance, high price and low power consumption. It is inconvenient to clean the oil net, and it is easy to encounter oil dripping.
3. Side suction range hood
Based on aerodynamics and fluid mechanics, the principle of separating oil fume by using the oil fume separation plate on the ground before exhausting clean air is designed. It is characterized by good smoke exhaust effect, and the smoke exhaust effect is above 99%. Don't drip oil, don't pick it up, hide it in the cupboard and integrate it with the cupboard, which doesn't take up space. The motor is non-stick, with long service life and convenient cleaning. Power saving is generally 160 watts. The oil fume does not pass through the breathing area, which ensures the health of housewives. The discharged clean air will not pollute the environment.
What should I do if the kitchen fumes can't be discharged?
1, the auxiliary flue must be kept.
Every kitchen has a flue, but do you know there is a main flue and an auxiliary flue? The main flue runs through the whole building. The auxiliary flue is relatively independent. It is separated from the main flue by a perforated partition, and the upper and lower parts are sealed by the floor. Generally, the lampblack at home will go to the auxiliary flue first, make a cache, and then enter the main flue through the hole in the partition, so as to ensure that the lampblack of every household is isolated and will not cross smoke.
Primary flue and secondary flue must exist at the same time. Some owners' houses are probably caused by connecting the smoke exhaust pipe to the main flue by mistake during decoration, or removing the auxiliary flue to save space. If the main flue is directly connected,
Because of its huge upward suction, it can be compared to "cupping effect". Once the air pressure is relatively low, it is possible to press other people's fumes into their own homes. The auxiliary flue has a good cache function and cannot be removed. 2, the details should be paid attention to in the construction
First of all, it is very important to choose the installation position of the range hood. Make sure that the pipes are as short as possible. Some owners will pull the pipe longer for the sake of beauty. After turning off the range hood in this way, there will be a lot of oil smoke in the pipeline that can't be discharged and then poured back indoors.
In addition, in order not to destroy the original main and auxiliary flue, its opening direction cannot be changed at will, and it must be drilled in the auxiliary flue. Owners can't change according to their own preferences. However, the hole of the flue can be enlarged, but be careful not to damage the baffle of the auxiliary flue.
3, often replace the check valve.
If you have removed the auxiliary flue, or need to prevent flue gas from flowing backwards, so much the better.
Experts suggest that you use the flue check valve. Many owners will question that the range hood already has a check valve, why should it be equipped with a flue check valve? In general, the function of the check valve of the range hood is not very significant, but installing the check valve in the flue can protect the range hood, so that the smoke in the flue will not flow back to the pipeline and the range hood. However, after installing the check valve, it should be cleaned regularly, otherwise it will make the check valve open and lose its function. And it is best to replace the flue check valve every two years or so.
