Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oil fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used because of their neatness, lightness, small footprint, good matching with wall cabinets, and low noise. [0003] The top suction range hood usually includes a smoke collection hood and a fan frame located on the smoke collection hood. A volute, an impeller and a motor for driving the impeller are installed in the fan frame. The negative pressure area is directly connected. This type of range hood has the problem of fast wind speed and strong negative pressure at the air inlet of the fume collecting hood...
