Abstract

The invention discloses a fan and a range hood with the fan. The fan comprises a volute and an impeller, wherein the impeller is arranged in the volute and comprises an impeller disc and a plurality of blades. The plurality of blades are arranged at intervals in the circumferential direction of the impeller disc. The fan further comprises a drainage device. An inner cavity and a gas inlet hole communicating with the inner cavity are formed in the impeller disc. Cavities are formed in the blades, and gas outlet holes communicating with the cavities are formed in the surfaces of the blades. Theinner cavity of the impeller disc communicates with the cavities of the blades. One end of the drainage device is arranged on the outer side of the volute and communicates with a volute tongue part ofthe volute, and the other end communicates with a gas inlet hole of the impeller disc. Noise generated in the working process is small, so that the noise level of the range hood can be optimized.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a fan and a range hood equipped with the same. Background technique [0002] In related technologies, range hoods have become one of the indispensable kitchen appliances in modern families, wherein air volume, wind pressure and noise are the core indicators of range hoods. When asked what problems consumers encountered when using range hoods at home, 85% of consumers would mention that range hoods have low suction power and unsatisfactory range hood effects. It is the biggest demand for them to buy range hoods. In recent years, the entire industry has collectively entered the era of high suction power, and high-suction range hoods have become the first choice for consumers to buy range hoods. The market share of high-suction range hoods has risen far faster than other types of range hoods, and it has really won the majority of consumers. generally recognized by the ...
