Problems solved by technology

Because of the inclination structure of the range hood in the related art, part of the sound emitted from the inner air inlet (fan air inlet) will be reflected and transmitted to the lower outer air inlet (close to the human ear), so when using In this state, the range hood is loud

Embodiment Construction

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0033] It is understandable that the sound quality of the range hood in use is the sound that users can actually feel. The core problem that needs to be overcome in the range hood is not only noise reduction but also sound quality reduction. Due to the low installation position of the side suction range hood, the position of the fan inside the side suction range hood is closer to the human ear, so under the same use condition, the loudness of the side suction range hood is higher than that of the top suction range hood. Much bigger.

Abstract

The invention discloses a kitchen ventilator. The kitchen ventilator comprises a housing, a volute and a flow guide cover, wherein a condensing plate is arranged at the front side of the housing; the volute is arranged in the housing, and an inner air inlet is formed in the volute; the flow guide cover is arranged in an air inlet channel which extends from the condensing plate to the inner air inlet; a plurality of through holes are formed in the flow guide cover; the flow guide cover is arranged opposite to the inner air inlet; and the flow guide cover is positioned at the upper part of a central axis of the volute. According to the kitchen ventilator in the embodiment, the flow guide cover is arranged at the upper part of the central axis of the volute, so that some sound transferred from the inner air inlet can be reflected to downwards spread, the sound is spread in the direction far away from human ears, and as a result, the noise produced by the kitchen ventilator in a working state is reduced, and the user experience is increased.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood. Background technique [0002] The sound quality in the use state is the sound of the range hood that users can really feel. The core difficulty of the range hood is to reduce the sound quality besides noise reduction. Because the range hood in the related art has an inclination structure in its inner diversion structure, part of the sound emitted from the inner air inlet (fan air inlet) will be reflected and transmitted to the lower outer air inlet (closer to the human ear). In the state, the range hood is louder. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] For this reason, the present invention proposes a range hood, which has low loudness and good user experience. [0005] The range hood according to the embodiment of the present invention includes...
