Abstract

The invention discloses an extractor hood. The extractor hood comprises a machine shell, a volute fan and a rectifying device; the volute fan is arranged in the machine shell, and the machine shell is internally provided with a flue gas channel communicated with a volute gas inlet; the rectifying device is arranged in the flue gas channel and is opposite to the volute gas inlet; a rectifying flue is limited between the rectifying device and the volute gas inlet, and the rectifying device is arranged to be adjustable relative to the position of the volute gas inlet so as to increase or decrease the flue gas flow inside the rectifying flue in the unit time; and according to the extractor hood, the rectifying device is arranged to be adjustable relative to the position of the volute gas inlet so as to increase or decrease the flue gas flow inside the rectifying flue in the unit time, and therefore cyclone, steaming around and the noise generated before lampblack is guided into a volute are avoided; and accordingly, the working noise and the air amount losses of the extractor hood are effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of home appliances, and more specifically, to a range hood. Background technique [0002] In top-suction range hoods, especially T-type top-suction range hoods, the volute fan continuously rotates to form a negative pressure area in the volute, and the oil fume on the cooktop continuously rises into the flue gas channel and is then introduced into the volute. Due to the lack of an effective rectifying device on the front side of the air inlet of the volute, the oil fume is easy to generate cyclone, circumvention and noise before being introduced into the volute. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems at least to a certain extent. [0004] Therefore, the present invention proposes a range hood, which has low operating noise and small air volume loss. [0005] The range hood according to the embodiment of the present inv...
