What common knowledge does the range hood flue have? Precautions for range hood flue

Nowadays, every household in the street has begun to install range hoods. I believe that every household is considering how to install a flue after using a range hood. However, since the types on the market are also very There are so many that consumers don’t know how to choose. So what common sense do you have when using a range hood? What do you need to pay attention to when using it? Next, let the editor take everyone to understand the range hood flue. Some common sense content.

1. Common sense about range hood flues

1. Range hood: For public flues, the developer will reserve a headwind board (to prevent other people’s smoke from entering your home). At first, it is The lower position needs to be removed because the tiles are installed. After the tiles are installed, they are moved up to the gusset plate. Therefore, don’t forget to install the upwind plate. If you lose it, buy one and install it.

2. The range hood is 15CM or 16CM at most, and there are two specifications: 16CM or 18CM! The original upwind plate is 15CM, and the range hood has a variable diameter, so don’t worry. If you buy it later, choose the 151618 universal one. That kind of thing! Range hoods are 15cm European style and 16CM, Fotile, Sacon, and the bosses are all 18cm. The ultimate goal of the flue in the public house is to prevent smoke from falling back.

2. Today’s gas water heaters are all forced exhaust type, and the flue is a must. The hole size is 6CM, and in the Northeast region it is 8CM. Because the wind there is relatively strong, it needs to be thicker. If the gas water heater The back of the installation location is outdoors, and the holes can also be drilled under the gusset plate. The stainless steel exhaust pipe is still very beautiful. Since the flue is on the gusset plate, it is strongly recommended to use an aluminum gusset plate for easy disassembly and maintenance.

2. Precautions for the range hood flue

1. Check whether the outlet of the flue, that is, the inlet of the range hood hose, has been changed from the front of the flue to Side? Because the side width of the side auxiliary flue is only 100mm, which is much narrower than the large side. According to the principle of aerodynamics, if you change the air inlet to the position of the auxiliary flue, it will reduce the rising speed of air emission and increase the resistance of emission. When the air in your kitchen and flue convection, the kitchen air pressure will be less than the flue air pressure. Even if your range hood is not working, the result will be smoke. Must be changed back.

2. Whether the kitchen door or window is open. If the window is not open when your range hood is working, air convection cannot be formed, resulting in the oil smoke not being discharged at all; when the range hood is not working, if the window is not open, the air pressure in your kitchen will be less than the air pressure in the flue, and other people's It is inevitable that oil fumes will flow back into your home.

3. Check whether the power of your range hood reaches 500m3/h. If not, please replace it in time.

4. Check whether the catering fume emissions from the building where you live (according to design regulations, catering fume emissions should be emitted separately) are connected to the residential kitchen flue. If so, then I congratulate you, the oil fumes will always flow back into your home. Because the power of the catering range hood is 2000m3/h, both the emission volume and the emission speed are much faster than that of your home range hood.

5. Check whether the flue air inlets of the residents upstairs and downstairs within the vertical range of your home are open or check valves are not installed, especially if the flue air inlets of the residents upstairs are open. , Failure to install a check valve will directly cause the oil fumes from downstairs in your home to pour back into your home.
