Description

   Outdoor ventilation hood   

An outdoor ventilation hood of the present invention, especially a technology applied to the field of exhaust air on a building, has the main technical feature of being able to reliably discharge indoor foul gas to the outside while maintaining the freshness of the indoor air and further reducing the interior The occurrence of turbulence prevents the backflow of dirty gas, thereby achieving the effect of smooth exhausting.

During the construction of the building, in order to make sure that the foul gas generated indoors during the future residence can be surely discharged and avoid affecting the people in the room, holes such as windows and exhaust fans can be reserved to allow indoor and outdoor circulation. Installation of windows, exhaust fans, exhaust hoods and other related equipment, among which the exhaust hood is used by many people today, and the early exhaust hoods have a considerable volume in design, so they are often installed in buildings It will cause the appearance of the building to have obvious convex objects, which is unsightly and uneven for the visual senses. Therefore, relevant industry players have worked hard to think and improve, and then introduced a small-volume exhaust hood, please See the Republic of China Patent Bulletin No. M396379 "Exhaust hood", mainly for installation on the external wall of the building. The external wall of the building is formed with a ventilation hole. The exhaust hood includes a casing and a duct. Combined with the duct, the casing and the duct are fixed on the exterior wall of the building, and a curved airflow path is formed at the front end of the ventilation hole, which can prevent rain or insects from entering directly. In addition, the duct is projected outside the building's exterior wall after assembly to prevent insects from crawling into the vent hole.

The above-mentioned "exhaust hood" is one of today's common devices for providing indoor exhaust. Although it does have a small volume, it can more effectively discharge indoor foul gas through the curved shape formed by the front end of the ventilation hole. Letting the air flow flow smoothly can even prevent insects from crawling in, but the wind direction must be changed according to weather considerations. In addition to the foul gas emitted indoors, the intersection of the two wind directions in the casing is prone to turbulence. If the wind direction is not directional, the discharged foul gas may circulate in the casing, so that it will be recharged into the room from the direction of the cover. In this way, the foul gas will not be discharged smoothly and inhalation will affect health, and even There are problems such as foreign objects entering the room together with the recharge of the airflow. Therefore, how to ensure that the wind and foul gas in the casing can be discharged in the correct direction as expected and reduce the occurrence of turbulence is the direction that industry players must start to improve.

In view of the above situation, the inventor has invested a lot of time in researching related knowledge, comparing various advantages and disadvantages, conducting research and development of related products, and going through multiple experiments and tests, and finally introduced an "outdoor ventilation hood" to improve the above Missing to fit the needs of the public.
