Abstract

The invention relates to the technical field of fans, and discloses a fan. The fan comprises an impeller and a filter screen arranged on the air inlet end face of the impeller. The filter screen comprises a main air inlet screen face and a side air inlet grid set, the side air inlet grid set comprises a plurality of grid sheets which are arrayed along the circumferential edge of the main air inletscreen face and formed by extending towards the impeller, and side air inlet channels are formed between the adjacent grid sheets. The design of combining the main air inlet screen face and the sideair inlet grid set is adopted for the filter screen of the fan provided by the embodiment, under the condition of guaranteeing the filtration effect of the main air inlet screen face on soot from theair inlet direction, the side air inlet grid set can be used for increasing the negative-pressure suction acting force on soot in the non-air-inlet direction around the fan and achieving adsorptive filtration of the soot, and thus the soot discharge effect and the soot filtration effect of a whole range hood are guaranteed. The embodiment of the invention also discloses the range hood.

Description

technical field [0001] The present application relates to the technical field of fans, for example, to a fan and a range hood. Background technique [0002] The range hood is currently a more commonly used household smoke exhaust device, which can discharge the oil fume in the kitchen environment to the outdoor environment, thereby reducing the amount of indoor oil fume and purifying the sanitation of the kitchen environment. The range hood mainly consists of components such as a smoke collection chamber, a flue, and a fan. The fan is the core of the range hood as the power source for conveying smoke. Too much oil will affect the operating efficiency of the fan. In view of the above situation, some fans in the related art will have a filter on the air inlet side of the fan impeller, so that most of the oil in the flue gas can be absorbed by the filter before the flue gas enters the fan. [0003] In the process of implementing the embodiments of the present disclosure, it i...
