Description

technical field [0001] The invention relates to a kitchen fresh air fan, in particular to a kitchen fresh air fan with a fresh air curtain, which belongs to the technical field of air purification. Background technique [0002] In the ten years since the national implementation of the "Indoor Air Quality" standard, people's understanding of indoor air quality has become deeper and deeper, and the improvement of indoor air quality has become an urgent requirement for people. Indoor air pollution sources are mainly in the kitchen and bathroom, and the kitchen is the most serious place for oxygen consumption, polluted gas and cooking fume. The use of range hoods does not completely solve the air pollution in the kitchen, and produces negative pressure and outdoor pollution gases to cause secondary pollution to the room, which is specifically reflected in: [0003] 1) Generate negative pressure: The better the room is sealed, the more severe the negative pressure will be. The ...
