When closing the doors and windows, there will be no loop, the exhaust hole of the ventilation fan will not absorb the gas in the flue, and your flue is connected to the kitchen and bathroom. Range hood inhales. Because of the suction effect of the range hood, the range hood needs to inhale while exhausting the smoke.
That's it, where does this gas come from, open the smoke machine--- inhale --- the air outside the window into the --- smoke machine exhaust. When you open the window, the indoor air pressure decreases. Solution, and then ventilated through the bathroom fan out?
Because the window is closed, start the range hood and let the wind blow inside, there are gaps, which can't block the reverse flow of air, and the check valve in your bathroom is not very good. The hood --- flue --- ventilation fan--- passes through the indoor --- and then to the hood, that is, opens when cooking and opens the kitchen window while cooking. Or install a ventilation fan on the kitchen window and exhaust the hood Hello.
Hope it helps.

Three methods: 1. You can change one of the smoke exhaust to another flue;
2. Ask someone to drill another hole, which leads directly to the outside of the wall to solve a smoke exhaust problem;
3. Replace the more flexible headwind plate.
Do you see if there's a knot at the top of that drawstring? The ventilation fan in the toilet in my bedroom is like that, and then the part of the fan that connects the drawstring can be stuck on one side of the knot and the other side can't be stuck, and when I pull the rolling rope, it opens in a different direction, and I don't know if it's like this.
First, the size of the exhaust fan.
First of all, let's talk about the size selection of bathroom exhaust fan, there are many styles and sizes of bathroom exhaust fans, the general bathroom exhaust fan is the same as the most common oil extraction fan, and the bathroom without windows will almost install such an exhaust fan, the size of this exhaust fan; Frame size, which is the specification of most ordinary exhaust fans. Some bathroom exhaust fans are a kind of enclosed type, and their functions are similar to the first type of exhaust fans, but there are certain differences in appearance. This exhaust fan size is generally such a square design. >>>More
The function of installing exhaust fans in the kitchen is mainly to accelerate the discharge of hot gas, keep the air in the kitchen fresh, and discharge the fumes when cooking or use the exhaust hood, the exhaust air volume of the range hood is several times that of the exhaust fan, and the range hood has the effect of adsorption and filtration for the fume, the motor and impeller are also designed to take into account the cleaning and removal after the accumulation of fumes, and the blades and air ducts of the exhaust fan, as well as the rainproof shutters, are basically designed to discharge water vapor and turbidity, and there is basically no defense against the fumes. After the smoke adsorption, the plastic parts will be deformed, soft, and can not be thoroughly cleaned, if the ventilation fan is cleaned with a strong acid and alkali, the basic ventilation fan will be scrapped, so the correct way to install the exhaust fan in the kitchen is to install a partition exhaust fan in the place close to the ceiling, away from the window of the stove, install a partition exhaust fan, the air volume can be installed larger, when the range hood is opened, the exhaust fan is turned on together, which plays the role of auxiliary exhaust, and the exhaust fan in the kitchen does not need to consider the noise too much, and the noise is smaller than that of the range hood. Static M&E Technology can advise you on the installation of exhaust fans in the kitchen.
The small ventilation fan of the toilet can be turned off with infrared, and a receiver is required to achieve this function.
