Description

Kitchen and Toilet Blower Fans and Vents Vent Blower {omitted}

The present invention relates to a kitchen and toilet blower fan and a ventilation ventilator, specifically, a multi-family house such as an apartment has a separate ventilation vent and centralized ventilation vents. In the case of the ventilation openings, the influx of excessive winds, automobile exhaust gas, etc. were prevented due to typhoons, natural rains, etc., and the centralized ventilation openings were used by several generations to use the same ventilation facilities. The various contaminated air toilets generated by cooking in the ventilation system blocked contaminated air that may be caused by backflow, such as the smell of toilets in the male's house. In the case of kitchen and toilet blowers, there is a backwind blocking damper of the blower fan. The crack causing backwind due to the steaming caused by If the air gap is not completely blocked and the gap between the gaps is compensated for, the cracks will dry out.Therefore, the ventilation plate damper does not open quickly. It is to provide a reverse wind breaker that can provide a pleasant living environment by effectively blocking odor and polluted air flowing back into the ventilation system.

In the case of apartments shared by multiple households, the kitchen and toilet ventilation holes are used to exhaust the polluted air in the room when the blower fan is driven to the centralized ventilation system piped in the vertical direction of the building and the individual ventilation facilities piped by each household. I can do it. In this case, however, the centralized ventilation facility installs a ventilation fan on the roof of the building to exhaust the polluted air from the common piping into the natural wind.However, the direction of the wind is not constant. In case of problems, individual ventilation system is equipped with a simple structure of reverse wind breaker on the outside of the household ventilation system, but it cannot fulfill its role, and the configuration installed in the damper of the blower fan is insufficient to completely block the reverse wind In addition, it was difficult to provide a pleasant living environment due to the inflow of food, smell, and automobile exhaust from other houses through these vents.

Thus, the present inventors have drawn out the present invention by sweeping the problems of the conventional kitchen and toilet blowing fan and the ventilation port.

In other words, the present invention imposes a separate electric backwind breaker on the existing blower fan and the ventilation port to open the blower fan when it is operating and to shut off the blower fan, thereby blocking the polluted air from the ventilation device of the household. This invention has been completed with the technical task of devising to provide a comfortable living environment by preventing the back wind of unnecessary wind.
