Fan assembly and exhaust hood

Abstract

The invention relates to the field of home appliances, and discloses a fan assembly and an exhaust hood. The fan assembly comprises a volute (1), an impeller (2) and a cleaning device (3), wherein theimpeller is mounted in the volute; the cleaning device comprises a jet mechanism capable of performing reciprocating motion; and a nozzle (31) of the jet mechanism is positioned between the outer circumferential wall of the impeller and the inner circumferential wall of the volute, and used for jetting a cleaning medium towards the outer circumferential wall of the impeller in a reciprocating moving manner; Through the above arrangement, the area of the cleaning effect of the nozzle on the inner circumferential wall of the volute can be greatly increased, the dead corner of cleaning can be reduced, and then oil dirt gathering on the impeller and the volute can be more effectively removed; and consequently, not only can the exhaust effect of the fan assembly and the exhaust hood be improved, but also the operation noise of the complete exhaust hood can be effectively reduced and the user experience can be improved.

Description

technical field [0001] The invention belongs to the field of household appliances, and in particular relates to a fan assembly and a range hood. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of people's living standards, range hoods that can purify the kitchen environment have been widely used in people's lives. Among them, the range hood uses the high-speed rotating impeller in the fan assembly to quickly suck away the harmful oil fume generated during the cooking process, and then discharge it outside. [0003] After the range hood is used for a long time, a large amount of oil will accumulate on the impeller and the inner wall of the volute in the fan assembly. The exhaust effect of the range hood will be affected. Of course, a large amount of oil stains accumulate in the fan components, which will also increase the operating noise of the fan components and even the whole machine, which will bring ...

AI Technical Summary

Problems solved by technology

[0003] After the range hood is used for a long time, a large amount of oil will accumulate on the impeller and the inner wall of the volute in the fan assembly. The exhaust effect of the range hood has an impact

Of course, a large amount of oil accumulation in the fan components will also increase the operating noise of the fan components and even the whole machine, bringing users a bad experience

[0004] When the fan assembly in the range hood needs to be cleaned, the conventional method currently used in the market is to spray the cleaning medium from the air inlet of the fan assembly towards the impeller, but due to the obstruction of the impeller, most of the cleaning medium is difficult to reach the inner peripheral wall of the volute. Clean the inner peripheral wall of the volute, resulting in unsatisfactory cleaning effect
