Abstract
The invention discloses a range hood with a noise reduction structure. The range hood comprises a centrifugal wind wheel set and an air duct shell, wherein the centrifugal wind wheel set comprises a wind wheel, a motor and a volute and is arranged in the air duct shell; an air inlet of the air duct shell is perpendicular to an air inlet surface of the centrifugal wind wheel set; two opposite side faces which are parallel to a radial surface of the wind wheel inside the air duct shell are provided with a rectification plate respectively in reference to the mounting and using direction; the two rectification plates are positioned on the two opposite sides of the air inlet position of the centrifugal wind wheel set respectively and are fixed inside the air duct shell; and due to the effect of the rectification plates, oil smoke cannot form turbulence at the air inlet and noise is not produced to fulfill the aim of reducing noise.
Description
Technical field
The present invention relates to a kind of range hood, particularly a kind of range hood of noise reducing type structure.
Background technology
At present, European range hood does not have denoising structure in the both sides of blower fan, and when blower fan rotated, powerful air-flow directly sucked by two air inlets of blower fan both sides, formed eddy current or turbulent flow at two air inlet places of blower fan both sides, made the noise at air inlet place higher.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of range hood of noise reducing type structure, this noise reducing type range hood can effectively reduce its noise.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of range hood of noise reducing type structure, it comprises centrifugal type wind wheel group and air channel housing, described centrifugal type wind wheel group comprises wind wheel, motor and volute, described centrifugal type wind wheel is mounted in the housing of air channel, air channel housing air inlet is vertical with the air intake surface of centrifugal type wind wheel group, to install and use direction is benchmark, the housing inboard two relative side that parallels with the wind wheel sagittal plane in described air channel is respectively equipped with a cowling panel, two cowling panels lay respectively at the two opposite sides of centrifugal type wind wheel group air inlet position, and two cowling panels are fixed in the inboard of air channel housing, oil smoke can arrive air inlet by cowling panel smoothly, and can't form turbulent flow in the air inlet position owing to the effect of cowling panel, thereby can't produce excessive noise.
As a further improvement on the present invention, described two cowling panels are parallel with air channel housing air inlet air intake direction and be fixed in the inboard two relative side of air channel housing perpendicular to the inboard two relative side of air channel housing.
As a further improvement on the present invention, the axial line of the center of described two cowling panels and centrifugal type wind wheel group is axially aligned.
As a further improvement on the present invention, the width of described two cowling panels is 5～300mm.
As a further improvement on the present invention, the lateral cross section of described two cowling panels is a kind of in " T " shape or " L " shape, conveniently is used for fixing on the housing of air channel.
The invention has the beneficial effects as follows: it comprises centrifugal type wind wheel group and air channel housing, described centrifugal type wind wheel group comprises wind wheel, motor and volute, described centrifugal type wind wheel is mounted in the housing of air channel, air channel housing air inlet is vertical with the air intake surface of centrifugal type wind wheel group, to install and use direction is benchmark, the housing inboard two relative side that parallels with the wind wheel sagittal plane in described air channel is respectively equipped with a cowling panel, two cowling panels lay respectively at the two opposite sides of centrifugal type wind wheel group air inlet position, and two cowling panels are fixed in the inboard of air channel housing.Because the effect of cowling panel, oil smoke can't go out to form turbulent flow at air inlet, can't produce noise, thereby reach the effect of noise reduction.

The specific embodiment
Embodiment: a kind of range hood of noise reducing type structure, it comprises centrifugal type wind wheel group 1 and air channel housing 2, described centrifugal type wind wheel group 1 comprises wind wheel, motor and volute, described centrifugal type wind wheel group 1 is located in the air channel housing 2, housing 2 air inlets in air channel are vertical with the air intake surface of centrifugal type wind wheel group 1, to install and use direction is benchmark, the housing 2 inboard two relative sides that parallel with the wind wheel sagittal plane in described air channel are respectively equipped with a cowling panel 3, two cowling panels 3 lay respectively at the two opposite sides of centrifugal type wind wheel group 1 air inlet position, and two cowling panels 3 are fixed in the inboard of air channel housing 2, oil smoke can arrive air inlet by cowling panel 3 smoothly, and can't form turbulent flow in the air inlet position owing to the effect of cowling panel 3, thereby can't produce excessive noise.
Described two cowling panels 3 are parallel with air channel housing air inlet air intake direction and be fixed in air channel housing 2 inboard two relative sides perpendicular to the inboard two relative side of air channel housing.
The axial line of the center of described two cowling panels 3 and centrifugal type wind wheel group 1 is axially aligned.
The width of described two cowling panels 3 is 5～300mm.
The lateral cross section of described two cowling panels 3 is a kind of in " T " shape or " L " shape, conveniently is used for fixing on air channel housing 2.
