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 of a certain angle with the horizontal line, 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 against the wind inlet gate. The cross section of the first guiding plate appears a right angle ladder shape with sloping side vertical with shafts of the fan and the wind inlet gate. A second guiding plate and a third guiding plate can be equipped between the fan and the bottom of the first guiding plate, wherein the second guiding plate is against the gap between the wind inlet gate and the first guide plate. A third guide plate is equipped between the fan and the oil net assembles wherein the cross section of the third guide plate 5 can adopt multiple folded line structure. 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 and horizontal line are an angle, air inlet place in housing is provided with first deflector, and first deflector is fixedly mounted on the housing and is right against air inlet.
The utility model can be further perfect by following manner:
The cross section of first deflector described in the utility model is at right angles trapezoidal, the axis normal of its hypotenuse and blower fan and air inlet.
The utility model can also be provided with second deflector in the lower end of the air inlet and first deflector, second deflector is right against the space between the air inlet and first deflector, wherein circular arc can be adopted in the second deflector cross section, and its circular arc concave surface is right against the space between the air inlet and first deflector.
The utility model can also be provided with the 3rd deflector between the lower end of blower fan and oily screen component, wherein many broken line types structure can be adopted in the cross section of the 3rd deflector 5.
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 7, 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 and horizontal line are an angle, air inlet 2 places in housing 7 are provided with first deflector 3, first deflector 3 is fixedly mounted on the housing 7 and is right against air inlet 2, to reduce the eddy current of air inlet; Wherein the cross section of first deflector 3 at right angles trapezoidal (seeing L-shaped on the vertical view), the axis normal of its hypotenuse and blower fan 1 and air inlet 2.Be provided with second deflector, 4, the second deflectors, 4 cross sections in the lower end of the air inlet 2 and first deflector 3 and be circular arc, its circular arc concave surface is right against the space between the air inlet 2 and first deflector 3.Be provided with the 3rd deflector 5 between the lower end of described blower fan 1 and the oily screen component 6, wherein the cross section of the 3rd deflector 5 is many broken line types.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.
