Embodiment 1

[0047] The range hood provided by the present invention includes: a front dynamic filter screen 21, which is arranged on the output shaft of the biaxial motor 2, and is located between the centrifugal fan wheel and the concave edge 231 of the front oil guide ring; The distance between the wheels is L1, and the value of the distance ΔL1 from the front dynamic filter screen 21 to the centrifugal wind wheel is [0.45L1, 0.85L1]. When the range hood was working, the air with soot sucked by the front oil guide ring 23 impacted on the front dynamic filter screen 21 through the guidance of the front oil guide ring concave edge 231. Part of the air is sucked into the volute assembly 1 through the mesh on the front dynamic filter screen 21 , and part of the air is blocked by the dynamic filter screen and moves around the dynamic filter screen along the surface of the dynamic filter screen. Wherein, the whole machine of the range hood has a shell, and the position of the dynamic filter i...

Abstract

A range hood provided by the invention comprises a front dynamic filter screen arranged on an output shaft of a double-shaft motor and located between a centrifugal wind wheel and a concave edge of afront oil guide ring, the distance between the concave edge of the front oil guide ring and the centrifugal wind wheel is L1, and the value of the distance L1 from the front dynamic filter screen to the centrifugal wind wheel is [0.45 L1, 0.85 L1]. When the range hood works, the air with the lampblack and sucked by the front oil guide ring impacts the front dynamic filter screen under the guide action of the concave edge of the front oil guide ring, part of air is blocked by the dynamic filter screen and moves towards the periphery of the dynamic filter screen along the surface of the dynamicfilter screen. The air moving along the surface of the dynamic filter screen continuously penetrates through the filter screen to enter a volute during the moving process, and finally a certain amountof air still passes through a gap between the front dynamic filter screen and the inner wall part of the front oil guide ring. In the scheme, the value of the distance L1 from the front dynamic filter screen to the centrifugal wind wheel is [0.45 L1, 0.85 L1], AND the air volume passing through the space between the front dynamic filter screen and the inner wall of the front oil guide ring can beadjusted, so that the noise generated by work of the front dynamic filter screen is lowered.

Description

technical field [0001] The invention relates to the technical field of range hood structures, in particular to a range hood. Background technique [0002] With the improvement of living standards, range hoods are important kitchen appliances. In addition to the basic performance of the range hood, users also pay special attention to the cleaning of the range hood, such as: no disassembly and cleaning, self-cleaning, etc. [0003] Such as figure 1 As shown, the dynamic filter type range hood includes a volute assembly 1 , and the volute assembly 1 is provided with two air inlets 11 and one air outlet 12 arranged oppositely. [0004] The volute assembly 1 is provided with a centrifugal wind wheel 3 , and the centrifugal wind wheel 3 is controlled by a biaxial motor 2 . The biaxial motor 2 is fixed in the volute assembly 1 through the fixing frame 13 . The fixing bracket 13 is fixed on the air inlet 11 on the rear side. The output shafts of the double-axis motor 2 protrude ...
