Abstract
A kind of blower of range hood, including spiral case, centrifugal wind wheel and motor, the preceding snail plate of spiral case are equipped with air inlet, and the outer circumferential surface of spiral case is equipped with air outlet；Centrifugal wind wheel includes bottom disk, tip circle ring seat plate and arc shaped blade, and the radial outside of the arc shaped blade is arc-shaped；The outer circumferential surface of the spiral case is in axial direction arc-shaped, and the central angle of the outer circumferential surface of spiral case is identical with the central angle of the radial outside of arc shaped blade；The arc shaped blade is made of alloy material.Due to using such structure, which has static pressure big, and wind pressure is stablized, the small feature of noise.
Description
Technical field
The utility model relates to a kind of blowers of fume-exhausting.
Background technique
Currently available technology, a kind of blower of range hood, including spiral case, centrifugal wind wheel and motor, the preceding snail plate of spiral case
It is equipped with air inlet, the outer circumferential surface of spiral case is equipped with air outlet；Centrifugal wind wheel includes bottom disk, tip circle ring seat plate and straight flange leaf
Piece.There are problems to be: wind pressure is unstable, and noise is big.
Utility model content
The purpose of this utility model is: providing a kind of blower of range hood, it has, and static pressure is big, wind pressure is stable, noise
Small feature.
The utility model is realized in this way: a kind of blower of range hood, including spiral case, centrifugal wind wheel and motor, snail
The preceding snail plate of shell is equipped with air inlet, and the outer circumferential surface of spiral case is equipped with air outlet；Centrifugal wind wheel includes bottom disk, tip circle ring seat
Plate and arc shaped blade are characterized in that the radial outside of the arc shaped blade is arc-shaped；
The outer circumferential surface of the spiral case is in axial direction arc-shaped, the central angle of the outer circumferential surface of spiral case and arc shaped blade
The central angle of radial outside is identical.
A kind of blower of range hood is characterized in that the arc shaped blade is made of alloy material.
A kind of blower of range hood is characterized in that the axis and the air inlet of the centrifugal wind wheel
The axis of mouth is overlapped, and the diameter of air inlet is greater than the overall diameter of the tip circle ring seat plate.
A kind of blower of range hood is characterized in that the air outlet is located at the second quadrant, it is described from
Gap between heart wind wheel and the circumferential siding inner surface of spiral case is by third quadrant, fourth quadrant, first quartile to the second quadrant
It is involute and is gradually increased.
A kind of blower of range hood of the utility model, due to using such structure, air-flow is unimpeded, and wind pressure is stablized, drop
Low noise.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model.
Fig. 2 is A-A view of Fig. 1.
Fig. 3 is the perspective view of the utility model.
Fig. 4 is the main view of the utility model.
Fig. 5 is the main view of the utility model arc shaped blade.
Fig. 6 is the perspective view of the utility model arc shaped blade.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of blower of range hood, including spiral case 1, centrifugal wind wheel 2 and motor 3, spiral case 1
Preceding snail plate 11 be equipped with air inlet 12, the outer circumferential surface of spiral case 1 is equipped with air outlet 13；Centrifugal wind wheel 2 include bottom disk 21,
The radial outside 231 of tip circle ring seat plate 22 and arc shaped blade 23, the arc shaped blade 23 is arc-shaped；
The outer circumferential surface of the spiral case 1 is in axial direction arc-shaped, the central angle and arc shaped blade of the outer circumferential surface of spiral case 1
The central angle of 23 radial outside is identical；
The arc shaped blade 23 is made of alloy material, and arc shaped blade is rigidly good, and hardness is good, is unlikely to deform, light-weight.It inhales
Wind-force increases, and wind pressure is stablized, and noise becomes smaller.
The axis of the centrifugal wind wheel 2 and the axis of the air inlet 12 are overlapped, and the diameter of air inlet 12 is greater than the top
The overall diameter of annulus seat board 22.
As shown in Figure 1, the air outlet 13 is located at the second quadrant, the centrifugal wind wheel 2 and table in the circumferential siding of spiral case 1
Gap between face is involute to the second quadrant and is gradually increased by third quadrant, fourth quadrant, first quartile.
As shown in Figure 1, centrifugal wind wheel 2 rotates counterclockwise.
Above-described is only the preferred embodiments of the utility model.It should be pointed out that for the common of this field
For technical staff, in the case where not departing from the utility model principle, it can also make several improvements and modification, this is also considered as
The protection scope of the utility model.
