Abstract

The invention discloses a range hood and a volute thereof. The range hood includes: a casing provided with a first external air exit and a second external air exit; a volute disposed in the casing, with the volute body comprising a base plate, a top plate, and a side wall plate arranged between the base plate and the top plate and being equipped with an external air outlet communicated with the first external air exit and a second external air exit; a wind wheel disposed in the casing body, with the opening direction of the external air outlet being orthogonal to the opening direction of the second external air exit; and an external switching cover plate, which is movably disposed on the volute or casing between a first position where the first external air exit is opened and the second external air exit is closed and a second position where the first external air exit is closed and the second external air exit is opened, wherein the angle alpha between the external switching cover plate at the second position and the opening direction of the second external air exit is greater than 0 and smaller than 90 degrees. According to the embodiment of the invention, the range hood has the advantages of small air volume and wind pressure loss, high wind wheel efficiency, and low pneumatic noise, etc.

Description

technical field [0001] The invention relates to a range hood and a volute used for the range hood. Background technique [0002] In the related art, in order to facilitate the connection with exhaust flues at different positions for outdoor exhaust, the range hood is usually provided with a plurality of exhaust outlets with opening directions orthogonal to each other. The range hood provided with multiple air outlets has the defects of large air volume and air pressure loss, low efficiency of the wind wheel, and high noise. Contents of the invention [0003] This application was made based on the inventor's discovery of the following facts and problems: [0004] For example, the casing of a range hood with multiple air outlets in the related art is usually provided with a rear air outlet and an upper air outlet, and the opening direction of the rear air outlet and the opening direction of the upper air outlet are mutually positive pay. When the air is exhausted through ...
