Abstract

The invention discloses a smoke exhaust ventilator. The smoke exhaust ventilator comprises a machine body, a draught fan system, a lampblack collecting cover and an auxiliary draught fan; the draught fan system is connected with the machine body and suitable for generating the air flow; the lampblack collecting cover is connected with the machine body, an air way communicated with the draught fan system is limited by the lampblack collecting cover, the lampblack collecting cover comprises an inner cover body and an outer cover body which are arranged in a spaced manner, an auxiliary air way is limited between the inner cover body and the outer cover body, an air inlet communicated with the auxiliary air way is formed in the outer cover body, and air outlets communicated with the air way are formed in the bottom of the inner cover body and the bottom of the outer cover body in a spaced manner; the auxiliary draught fan is arranged in the auxiliary air way to generate the air flow. According to the smoke exhaust ventilator, lampblack can be promoted to flow, the aim of strong sucking of the lampblack can be achieved, and the lampblack sucking effect of the smoke exhaust ventilator is improved.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] In the range hood structure of the prior art, the motor shaft drives the fan to rotate to generate suction to achieve the function of extracting oil fume and absorbing dirt. Due to the high-speed motor noise and the size of the range hood fan, the motor speed is generally not high and the suction is limited. . Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a range hood, and the range hood blower can have sufficient suction when working, so as to achieve the purpose of sucking the oil fume forward. [0004] The range hood according to the embodiment of the present invention includes: a body; a fan system, which is connected to the body and is suitable for generating airflow; a fume collection hood, which is connected to the body, and...
