Problems solved by technology

Usually, the exhaust fan is fixed in the ceiling or wall, and the parts of the exhaust fan need to be connected with the outside world, so that the air can be sucked into the exhaust fan. The exhaust fan of the related art can remove the larger foreign matter by setting the air intake grille at the panel. It has a certain blocking effect, but the parts of the exhaust fan are exposed for a long time, and it is inevitable that small-sized foreign objects such as dust will enter the interior of the exhaust fan. At the same time, there are environmental factors such as temperature, humidity, and light, which are easy to cause wear and tear on the internal components and accelerate the speed of the components. The speed of aging affects the use effect of the exhaust fan

Description

technical field [0001] The invention relates to the technical field of exhaust fans, in particular to a panel opening and closing device and an exhaust fan. Background technique [0002] The exhaust fan is a type of air-conditioning appliance that is driven by a motor to rotate the blades to drive the airflow to exchange indoor and outdoor air, also known as a ventilation fan. The purpose of exhaust is mainly to remove indoor dirty air, so as to achieve the effect of adjusting temperature and humidity. Usually, the exhaust fan is fixed in the ceiling or wall, and the parts of the exhaust fan need to be connected with the outside world, so that the air can be sucked into the exhaust fan. The exhaust fan of the related art can remove the larger foreign matter by setting the air intake grille at the panel. It has a certain blocking effect, but the parts of the exhaust fan are exposed for a long time, and it is inevitable that small-sized foreign objects such as dust will enter...
