Range hood

Abstract

The invention discloses a range hood comprising a fume exhaust hood, a fume collection hood, a main draught fan system and auxiliary draught fan systems. An oily fume channel is defined in the fume exhaust hood. The fume collection hood is connected with the fume exhaust hood. The fume collection hood defines a fume collection cavity and auxiliary air channels communicating with the fume collection cavity, wherein the fume collection cavity communicates with the oily fume channel. The lower surface of the fume collection hood is open and forms an oily fume inlet. At least one of the outer top wall and the outer side wall of the fume collection hood is provided with an air inlet communicating with the auxiliary air channels. The inner side wall of the fume collection hood is provided with air outlets communicating with the auxiliary air channels and the fume collection cavity. The main draught fan system is arranged in the oily fume channel and used for sucking the oily fume in the fume collection cavity into the oily fume channel and discharging the oily fume in the oily fume channel out. The auxiliary draught fan systems are arranged in the auxiliary air channels and are used for sucking the oily fume around the air inlets into the auxiliary air channels and discharging the oily fume in the auxiliary air channels into the fume collection cavity. According to the range hood, the work noise and the energy consumption of the main draught fan system can be lowered, and oily fume leakage can be prevented.

Description

technical field [0001] The invention relates to a kitchen appliance, in particular to a range hood. Background technique [0002] In order to prevent oil fume leakage, the range hoods in the related art often use the method of increasing the power of the main fan system. Because the air volume of the range hood is too large, the air entering the kitchen doors and windows disturbs the airflow in the kitchen, which will reduce the range hood’s range hood. Effect, and the high-power main fan system will also produce greater noise. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] Therefore, the present invention proposes a range hood, which can not only prevent the leakage of oil fume, improve the smoking effect of the range hood, but also has low noise. [0005] The range hood according to the embodiment of the present invention includes: a fume outlet hood, a fume collecting ho...
