Abstract

The invention discloses an impeller, a draught fan and an extractor hood. The impeller comprises a wheel disc and multiple fan blades. The multiple fan blades are arranged in the circumferential direction of the wheel disc at intervals, an inner cavity is formed in the wheel disc, an air inlet communicating with the inner cavity is formed in the wheel disc, cavities are formed in the fan blades, air outlets communicating with the cavities are formed in the surfaces of the fan blades, the inner cavity of the wheel disc communicates with the cavities of the fan blades, and noise generated when the impeller rotates is low.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to an impeller, a fan and a range hood. 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 [0003] I...
