Description

Side exhaust equipment of building duct

The invention relates to a roof exhaust device, in particular to a building duct side exhaust device which can improve the exhaust effect.

According to the conventional building design, every toilet and bath will be designed to open windows as much as possible to improve ventilation and reduce humidity. However, it is quite common that the windows cannot be opened. Therefore, toilets and baths that cannot be opened will be equipped with drains. The fan allows the toilet bath air to be discharged from the exhaust fan to the exhaust duct of the building, and then discharged from the exhaust duct to the top floor of the building. Generally, the design of the exhaust duct adopts the natural exhaust method and uses the principle of rising air heat to make the air energy. It is continuously discharged upwards, but some odors or smoke odors are often flowed between the exhaust ducts and the toilet baths because the natural exhaust speed is too slow, which will seriously affect the air quality of the toilet baths and cause neighbors The reason is that some exhaust ducts will be equipped with an exhaust fan, and the exhaust fan is driven by electricity to achieve the purpose of exhausting the air. The exhaust fan is usually an exhaust tower, which is a rotating shaft blade Type, when the rotor blades drive the air to exhaust, part of the air flow will be pushed in the opposite direction of the exhaust, resulting in an increase in the driving resistance of the exhaust fan, which will not only reduce the exhaust flow rate, but also increase the power Consumption. Furthermore, if the exhaust fan fails, the exhaust fan will be difficult to repair and replace. Similarly, the exhaust fan is not easy to clean. The above-mentioned conventional shortcomings are all problems that the author wants to improve.
