Abstract

The invention discloses a range hood and a volute case thereof. The range hood includes: a casing provided with a first outer air outlet and a second outer air outlet; The side panel in between is provided with an outer air outlet connected to the first outer air outlet and the second outer air outlet, the opening direction of the outer air outlet is orthogonal to the opening direction of the second outer air outlet; the wind wheel, the wind wheel It is arranged in the volute body; and the outer switching cover plate, the outer switching cover plate is in the first position of opening the first outer air outlet and closing the second outer air outlet and closing the first outer air outlet and opening the second outer air outlet. The second position of the air exhaust port is movably arranged on the volute or the casing, wherein in the second position, the angle α between the outer switching cover plate and the opening direction of the second outer air exhaust port is greater than zero and less than 90 degrees. The range hood according to the embodiment of the present invention has the advantages of small air volume and wind pressure loss, high wind wheel efficiency, and low aerodynamic noise.

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 ...
