Description

technical field

[0001] The invention relates to a range hood, in particular to a combined blow-suction type range hood. Background technique

[0002] With the development of urbanization and people's pursuit of a good cooking environment, range hoods are generally installed in family kitchens. Due to the operating space requirements, there is an installation height of 65-80 cm between the range hood and the gas cooktop. The range hood has a certain range of capture energy efficiency area, generally within 40-45 cm below the range hood. It makes the range hood unable to fully inhale the oily fume and other harmful gases produced by cooking and fuel combustion, especially the small splashed particles. In addition, due to the country's requirements for building energy conservation, the airtightness of the kitchen envelope is getting better and better. On the other hand, cookers generally close the kitchen door due to cooking habits and preventing oil fume from spreading to o...
