Why does the exhaust fan in the kitchen blow the wind inside?

The reason why the kitchen exhaust fan blows the wind to the inside:

1. The fan is reversed or the electrodes are reversed. Specific solution: first check whether it is installed in reverse, and if it is excluded, check the wind direction transfer switch.

If there is no such switch, it is likely that the electrodes are connected in reverse. It's best to find a professional electrician to take a look. It is dangerous to repair it yourself.

2. The exhaust fan rotates outwards to make the speed of the outside air fast, and the pressure at the fast air speed is small, so that the outside air blows to the inside.

Causes the kitchen exhaust fan to blow the wind direction inside:

1. The fan is installed in reverse or the electrode is reversed. Specific solution: first check whether it is reversed, and then check the wind direction of the transfer switch, if there is no switch, it is likely that the electrode is reversed, it is best to find a professional electrician to take a look.

It can be dangerous to repair it yourself.

2. The exhaust fan rotates on the outside, so that the flow rate of the outside air is fast, and the pressure in the place where the air flow rate is fast is small, so that the outside air blows inside.

The main reasons for blowing in the wind direction are: the fan is reversed or the electrodes are reversed.

Specific solution: first check whether it is installed in reverse, and then check the wind direction of the transfer switch, if there is no switch, it is likely that the electrode is reversed, it is best to find a professional electrician to help you take a look.

The exhaust fan rotates on the outside, so that the flow rate of the air outside is fast, and the pressure of the air flow rate is small, so that the air outside blows inside.

Is it the wrong face of the fan? If you install the wrong surface, it will be like this, and there are some kitchen exhaust fans that are 2 functions, one blowing and one suction, you see if the switch is there.

It may be that the motor cable is reversed, causing the smoke exhaust fan to be turned into an electric fan, or the fan blades may be half installed in the opposite direction, resulting in the direction of the airflow inward. Thirdly, the middle emission light is bent excessively, and the exhaust airflow is not smooth. Eliminating the 3 reasons one by one should be solved. Hope it helps.

1. Wrong installation;

2. The exhaust fan in the kitchen exhausts the fumes to the outside, how can it be possible to exhaust the air inward.

The landlord should have installed the front and back of the fan blades of the exhaust fan upside down, and you should be able to disassemble it and reverse it.

1. Check whether the fan is installed indoors or outdoors, and adjust and reinstall it if it is wrong. 2. The wire (live wire-neutral wire) can be replaced.

If the fumes cannot be discharged, the fan is generally reversed; If it doesn't work, the line is reversed, just change it.

Drive fresh air into the kitchen, and roll out the smell of oil smoke in the kitchen to achieve air convection.

Is the kitchen in the home or the large kitchen of the unit hotel?Generally, the fan in the large kitchen is 380V, and if it is blown upside down, the line is reversed, and two of the lines can be replaced.

If it's the window-type kind, pull the switch cord again. It can be reversed.

If the blades of your exhaust fan are reversed, just change the blades to the other direction.

The machine is reversed, or the blade is reversed, or it is time to clean it.

Blowing outward is the right solution.

Kitchen exhaust fan is a kind of air conditioning appliance that drives the fan blades of the exhaust fan to rotate through an electric motor to drive the air flow in the kitchen, so that the air in the kitchen can be exchanged. That's why we also call it a kitchen fan. The kitchen exhaust fan has a large air volume, low price, low noise, low energy consumption, stable operation, fast exchange air flow speed and high efficiency.

The fan blades in the kitchen exhaust fan also provide a protection against dust and water.

The kitchen exhaust fan will reduce the air pressure in the kitchen while expelling the air to the outside, so the air in the kitchen will become thin and create a negative pressure zone. In this way, the air from the outside will flow into the room due to the difference in air pressure. The above is the principle of physical air pressure.

In addition, some kitchen exhaust fans also have the function of cooling, and the cooling principle is the principle of keeping the temperature equal.

Hope it helps.

Why does the exhaust fan in the kitchen blow the wind inside?

Hello, I am the teacher of Heqi Duan Lin Zhiyu, who is good at epidemic prevention and control information Life, travel, emotion, and game answers, and now I have been quietly rising to the reputation of the industry for 3 years, and I am happy to serve you Hello, I am querying relevant information for you here, please wait for a while with a smile!

The main reasons for blowing in the wind direction are: the fan is reversed or the electrodes are reversed.

Specific solution: first check whether it is installed in reverse, and if it is excluded, check the wind direction transfer switch. If there is no slow-burning switch, it is likely that the electrodes are connected in reverse.

It's best to find a professional electrician to take a look. It is dangerous to repair it yourself. 2. The exhaust fan rotates outward, so that the speed of the external air disturbs the void and fast, and the pressure at the fast air speed is small, so that the external air blows to the inside.

Dear, if you still don't understand something, you can prepare a book to continue to consult! You can also pay attention to me, if you don't understand any questions in the future, you can also consult me at any time, I will patiently answer for you! I wish you a happy life, and please give a thumbs up.
