Problems solved by technology

[0002] In the related art, in the volute of the range hood, there are two cavities at the outlet coaming. When the smoke flows through the outlet, the smoke will generate eddy currents in the two cavities, and the existence of the vortex will make the oil suction The hood loses part of the air volume and air pressure, and this is not conducive to the optimization and improvement of the noise of the range hood

Abstract

The invention discloses a volute of a range hood and the range hood. The volute comprises an outlet coaming, wherein a partitioning part is arranged at the outlet coaming so as to form an inner hole and an outer hole on two sides of the partitioning part; an accommodation cavity is further formed inside the volute; the accommodation cavity is further communicated with the inner hole; and the accommodation cavity and the outer hole are partitioned by the partitioning part. Therefore, through simple structure adjustment, the overall properties of the volute can be sufficiently improved through relatively small improvement. In addition, under same motor input, output of relatively high air amounts and air pressure can be achieved for the volute.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a volute of a range hood and a range hood with the volute. Background technique [0002] In the related art, in the volute of the range hood, there are two cavities at the outlet coaming. When the smoke flows through the outlet, the smoke will generate eddy currents in the two cavities, and the existence of the vortex will make the oil suction The hood loses part of the air volume and air pressure, and this is not conducive to the optimization and improvement of the noise of the range hood. 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. Therefore, the present invention proposes a volute of a range hood, which can reduce the loss of air volume in the cavity at the outlet coaming, and can improve the overall performance of the volute. [0004] The present invention ...
