Abstract
A kind of bidirectional rotation centrifugal wind wheel, including：Wheel hub and the impeller mechanism being wrapped on the outside of wheel hub；Wherein impeller mechanism includes：Inner ring, inner ring are wrapped on the outside of wheel hub；Outer shroud, outer shroud are wrapped on the outside of inner ring, and a space is formed between inner ring and outer shroud；Blade, multiple blades are circumferentially arranged and both ends are individually fixed on the inner peripheral surface of inner ring outer peripheral face and outer shroud, in space；First working face of blade is linear, and the second working face of blade is circular arc.Second working face is that circular arc is that protrusion is set.Multiple blades are evenly arranged in space.The working face of the blade both sides of the utility model bidirectional rotation centrifugal wind wheel is respectively designed to straight flange and arc-shaped edges.When turning clockwise, the straight flange working face of blade is in running order, now for the less demanding arc exhaust function of blast；During rotate counterclockwise, the arc-shaped edges working face of blade is in running order, now requires higher blowing function for blast.
Description
Technical field
It the utility model is related to mechanical field, more particularly to the air-supply technology of air conditioner, particularly a kind of noise reduction bidirectional rotary
Turn centrifugal wind wheel.
Background technology
Centrifugal wind wheel is widely used in various conditioners, particularly in air-conditioning cleaner, cabinet type split type sky
Adjust in device and largely used on the product such as machine, window machine, mobile air conditioner, dehumidifier.In general, pressure fan is low in energy consumption, air quantity is big, makes an uproar
These three low indexs of sound are the principal elements for weighing pressure fan performance quality.But no matter clockwise current centrifugal wind wheel is
Or rotate counterclockwise, the degassing function played are all fixed, function is relatively simple, it is impossible to meets the needs of different.
Utility model content
The purpose of this utility model is to provide a kind of bidirectional rotation centrifugal wind wheel that can adjust degassing function.
In order to solve the above technical problems, the utility model bidirectional rotation centrifugal wind wheel, including：Wheel hub and it is wrapped in described
Impeller mechanism on the outside of wheel hub；Wherein described impeller mechanism includes：Inner ring, the inner ring are wrapped on the outside of the wheel hub；Outer shroud,
The outer shroud is wrapped on the outside of the inner ring, and a space is formed between the inner ring and the outer shroud；Blade, multiple leaves
Piece is circumferentially arranged and both ends are individually fixed on the inner peripheral surface of the inner ring outer peripheral face and the outer shroud, positioned at the space
It is interior；First working face of the blade is linear, and the second working face of the blade is circular arc.
Second working face is that circular arc is that protrusion is set.
Multiple blades are evenly arranged in the space.
The working face of the blade both sides of the utility model bidirectional rotation centrifugal wind wheel is respectively designed to straight flange and arc-shaped edges.It is suitable
When hour hands rotate, the straight flange working face of blade is in running order, now for the less demanding arc exhaust function of blast；It is inverse
When hour hands rotate, the arc-shaped edges working face of blade is in running order, now requires higher blowing function for blast.
Brief description of the drawings
Fig. 1 is the utility model bidirectional rotation centrifugal wind wheel structural representation one；
Fig. 2 is the utility model bidirectional rotation centrifugal wind wheel structural representation two.
Embodiment
The utility model bidirectional rotation centrifugal wind wheel is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model bidirectional rotation centrifugal wind wheel, including：Wheel hub 1 and it is wrapped on the outside of wheel hub
Impeller mechanism 7.Wherein inner ring 2 is wrapped on the outside of wheel hub, and outer shroud 3 is wrapped in the outside of inner ring 2, between inner ring 2 and outer shroud 3
A space is formed, multiple blades 4 are circumferentially arranged and both ends are individually fixed on the inner peripheral surface of the outer peripheral face of inner ring 2 and outer shroud 3,
In even arrangement space, the first working face 5 of blade 4 is linear, and the second working face 6 of blade 4 is the circular arc of protrusion.Up time
When pin rotates, the first working face 5 of blade 4 is in running order, now for the less demanding arc exhaust function of blast；It is inverse
When hour hands rotate, the second working face 6 of blade 4 is in running order, now requires higher blowing function for blast.
The preferred embodiment created to the utility model above is illustrated, but the utility model is created not
It is limited to the embodiment, those skilled in the art can also make on the premise of without prejudice to the utility model creative spirit
A variety of equivalent modifications or replacement, these equivalent modifications or replacement are all contained in the application claim limited range
It is interior.
