Abstract

The invention discloses an extractor hood. The extractor hood comprises an extractor hood box body and a first fan assembly arranged in the extractor hood box body; the extractor hood box body is provided with a smoke inlet, an oil screen assembly is arranged on the smoke inlet, a rotational flow generation device and a second fan assembly are further included, the rotational flow generation device is provided with an air inlet, the side wall is provided with multiple air outlets used for forming the rotational flow, the rotational flow generation device is arranged below the oil screen assembly, and the air inlet is connected with an exhaust opening of the second fan assembly. According to the extractor hood, the rotational flow generation device is compact in structure and small in occupied space, under the joint effect of the rotational flow generation device and the first fan assembly, lampblack is guided to the smoke inlet in a manmade tornado shape, the lampblack path is effectively controlled, comprehensive smoke gathering is facilitated, and the lampblack sucking effect is improved.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood capable of forming a rotating smoking effect. Background technique [0002] The smoking process of the traditional range hood can be regarded as a point-sink type. With the increase of the distance from the smoking port, the negative pressure of this smoking method will drop sharply. How to reduce the diffusion of soot and improve the smoking effect of the hood has always been a technical problem to be solved in this field. [0003] The most simple and direct way is to increase the power of the fan. Although this can improve the suction and discharge effect, the improvement of the smoking effect is not obvious, and it will also cause noise and increase energy consumption. [0004] In addition, there are some range hoods that can form a tornado smoking effect. For example, the application number is CN201210396787.9 "A Rotating Air Curtain Range Hood with Fume Fil...
