Together.
Research has shown that the wind wheel piece of this kind of standard shape, can caused by air quantity easily reach bottleneck, centrifugal wind wheel turns
When speed is too high, can not improve air quantity again can only produce extra noise.
Therefore, it is necessary to further improve.
The content of the invention
The purpose of this utility model aims to provide a kind of small special-shaped centrifugal wind wheel of the big noise of air quantity, and it can bear bigger
Rotating speed, it is smaller to produce bigger air quantity, noise, to solve weak point of the prior art.
The small special-shaped centrifugal wind wheel of the big noise of a kind of air quantity designed by this purpose, including upper retainer plate, lower retainer plate and
The radial wind wheel piece set between them, fixed circle form air intake opening, air outlet, institute are formed between wind wheel piece
The side that wind wheel piece is stated towards centrifugal wind wheel center is wind cutting piece, and the outer rim of wind cutting piece from top to bottom becomes larger, wind wheel piece court
It is guide vane to the side outside centrifugal wind wheel, the outer rim of guide vane is equal sized from top to bottom.
The lower retainer plate is provided with rotation seat, and rotation seat center is provided with arbor mounting hole.
The rotation seat raises up, and the raised position that wind cutting piece corresponds to rotation seat is provided with clearance position, the shape of clearance position
It is suitable with the shape that rotation seat raises up.
The upper end of the wind wheel piece pierces into retainer plate and forms upper bending part by bending and snaps onto on upper retainer plate.
The lower end of the wind wheel piece pierces into lower retainer plate and forms lower bending part by bending and snaps onto on lower retainer plate.
The section of the wind wheel piece is in tabular or in arc-shaped.
The wind wheel piece is inclined between retainer plate and lower retainer plate, rotation direction of the wind wheel piece along centrifugal wind wheel
Tilt.
The utility model is had the advantages that by above-mentioned technological improvement：
By being improved to the structure of wind wheel piece, the area of wind cutting piece can be effectively increased and then improve wind cutting air quantity,
Centrifugal wind wheel can also be enable to bear bigger rotating speed, air quantity is further improved and reduce when centrifugal wind wheel tells rotation and produced
Raw noise.
The volume of centrifugal wind wheel is more compact, particularly useful as the wind wheel of range hood, helps the body for reducing range hood
Product.
Brief description of the drawings
Fig. 1 is the stereogram 1 of the utility model first embodiment.
Fig. 2 is the stereogram 2 of the utility model first embodiment.
Fig. 3 is the stereogram 1 of the utility model first embodiment wind wheel piece.
Fig. 4 is the stereogram 2 of the utility model first embodiment wind wheel piece.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Referring to Fig. 1-Fig. 4, the small special-shaped centrifugal wind wheel of the big noise of this air quantity, including upper retainer plate 1, lower retainer plate 2 and be in
The wind wheel piece 3 being radially positioned between them, fixed circle 1 form air intake opening, air outlet are formed between wind wheel piece 3,
When centrifugal wind wheel rotates, from air intake opening air intake, after the centrifugation wind cutting of wind wheel piece 3, from air outlet.
As shown in Figure 3 and Figure 4, wind wheel piece 3 is using dotted line as boundary, is divided into wind cutting piece 31 and guide vane 32, wind wheel piece 3 towards from
The side at heart wind wheel center is wind cutting piece 31, and the outer rim of wind cutting piece 31 from top to bottom becomes larger, so as to form bigger wind cutting
The area of piece, it is possible to increase the wind cutting air quantity of unit speed, that is, improve intake, additionally it is possible to enable centrifugal wind wheel to bear bigger
Rotating speed, further improving air quantity simultaneously reduces caused noise when centrifugal wind wheel tells rotation, and will not increase centrifugation wind
The volume of wheel, the volume of centrifugal wind wheel are relatively more compact.Wind wheel piece 3 towards the side outside centrifugal wind wheel be guide vane 32,
The outer rim of guide vane 32 is equal sized from top to bottom, is easy to air-out.
Lower retainer plate 2 is provided with rotation seat 4, and the center of rotation seat 4 is provided with arbor mounting hole 41, and arbor mounting hole 41 can be with electricity
Arbor is installed, so as to drive the rotation of centrifugal wind wheel.
Rotation seat 4 raises up, and the raised position of the corresponding rotation seat 4 of wind cutting piece 31 is provided with clearance position 311, clearance position 311
Shape it is suitable with the shape that rotation seat 4 raises up, avoid wind wheel piece 3 from being interfered with lower retainer plate 2, rotation seat 4, be easy to
Their actual installation applications.
The upper end of wind wheel piece 3 pierces into retainer plate 1 and forms upper bending part 33 by bending and snaps onto on upper retainer plate 1,
Similarly, the lower end of wind wheel piece 3 pierces into lower retainer plate 2 and forms lower bending part 34 by bending and snaps onto on lower retainer plate 2, should
