Abstract
The utility model relates to an oil and smoke exhaust ventilator with a wind absorption and noise lowering structure, comprising a shell body, an oil net assemble and a fan, wherein the shaft of the fan is horizontal, the wind inlet gate inside the shell body is equipped with a first guiding plate, the first guiding plate is fixedly equipped on the shell body and is vertically against the wind inlet gate. The cross section of the first guiding plate in the utility model appears an oblong shape with straight sides on both sides round-arc transition. A second guiding plate and a third guiding plate can be equipped between both side in front and back of the fan and the oil net assemble in the utility model, wherein the second guiding plate and the third guiding plate are fixedly connected by two L shaped boards and then formed. The beneficial effects of the utility model is that guiding plates are added inside the shell body to guide air flow of the wind inlet gate to flow into the fan, thereby realizing the purpose of lowering noise of the whole machine and decreasing the convolution of the wind inlet gate.
Description
Technical field
The utility model relates to a kind of range hood, especially a kind of range hood with the air draught denoising structure.
Background technology
Original European range hood, air inlet place at blower fan is not provided with denoising structure, and when blower fan rotated, powerful air-flow directly sucked by air inlet, form stronger air inlet eddy current in the cavity between air inlet, housing and oily screen component, the noise at air inlet place is bigger.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of range hood that reduces the air inlet eddy current and reduce the air draught denoising structure of total noise of centrifuge is provided.
The utility model solves the technical scheme that its technical problem adopts: the range hood of this band air draught denoising structure, comprise housing, oily screen component and blower fan, the axis of blower fan is horizontal, air inlet place in housing is provided with first deflector, and first deflector is fixedly mounted on the housing and vertically is right against air inlet.
The utility model can be further perfect by following manner:
The cross section of the described first deflector described in the utility model shape that is rectangle, the straight flange arc transition of its both sides.
The utility model can also be provided with second deflector and the 3rd deflector between the lower end of the both sides, front and back of blower fan and oily screen component, wherein second deflector and the 3rd deflector are to be fixedlyed connected by two blocks of L shaped plates respectively and form.
The effect that the utility model is useful is: by increasing deflector, the air-flow of leading along air inlet enters blower fan in enclosure interior; Thereby reach the purpose that reduces total noise of centrifuge, and can reduce the eddy current of air inlet.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1-shown in Figure 11, the range hood of this band air draught denoising structure, comprise housing 7, oily screen component 6 and blower fan 1, the axis of blower fan 1 is horizontal, air inlet 2 places in housing 7 are provided with first deflector, 3, the first deflectors 3 and are fixedly mounted on the housing 7 and vertically are right against air inlet 2, to reduce the eddy current of air inlet, the cross section of first deflector 3 shape that is rectangle, the straight flange arc transition of its both sides.Between the lower end of blower fan 1 rear side and oily screen component 6, be provided with second deflector 4, second deflector 4 is right against the lower end of blower fan 1 rear side and the space between the oily screen component 6, second deflector 4 is fixedly connected and form by two blocks of L shaped plates, and its L shaped long limit is right against the lower end of blower fan 1 rear side and the space between the oily screen component 6.Be provided with the 3rd deflector 5, the three deflectors 5 and be by two blocks of L shaped plates fixedly connected and form between the lower end of blower fan 1 front side and oily screen component 6, its L shaped long limit is right against the lower end of blower fan 1 front side and the space between the oily screen component 6.The air-flow that second deflector 4 and the 3rd deflector 5 are used for leading along air inlet enters blower fan; Thereby reach the purpose that reduces total noise of centrifuge.
The structure of the utility model patent is not limited by baffle plate appearance and size, and shape can be designed to square, half elliptic etc., and the fixed form of structure is unrestricted.
