The utility model proposes a kind of wind wheel, the axial flow blower being provided with this wind wheel, cabinet air-conditioner and air-conditioner.
Cabinet air-conditioner has shell, and usual shell front side offers air outlet, and housing back panel offers air inlet, shell
Inside it is provided with axial flow blower and heat exchanger, when cabinet air-conditioner runs, axial flow blower directs outside air into inside the shell, and air exists
After inside the shell and heat exchanger heat exchange, from air outlet blowout.
In this utility model embodiment, as depicted in figs. 1 and 2, this wind wheel 10 has blade 11, and described blade 11 has
First side 11a on air intake direction and second side 11b, the thickness of described blade 11 is in described first side 11a direction
Gradual change on the direction of described second side 11b.
With reference to Fig. 3 and Fig. 4, axial flow blower has jacket 20, and jacket 20 has air intake and outlet air end, and wind wheel 10 is pacified

Side 11a flows to the second side 11b's of wind wheel 10.Due to blade 11 thickness in first side 11a towards described second side
Gradual change on the direction of 11b, so, blade 11 first side 11a towards corresponding various pieces on the 11b of second side deformation
Amount is variant.For example, the thermal deformation of blade 11 thicker part is slow, and thermal deformation amount is less, and the hot shape at blade 11 thinner thickness
Become very fast, thermal deformation amount is relatively large.So, when cabinet-type air conditioner internal temperature is higher, there is thermal expansion, the leaf of thicker part in blade 11
Piece 11 part is partly mutually involved with the blade 11 of thin location, and the thermal deformation amount of blade 11 will not be excessive.When cabinet-type air conditioner internal temperature
When low, blade 11 radially shrinks, and blade 11 part of thicker part and the blade 11 of thin location partly mutually involve, blade
11 amount of contraction also will not be excessive.Thus, the gap width between the inwall of blade 11 and jacket 20 is relatively stable, blade
11 will not be made a noise with the internal friction of jacket 20, and air-flow also will not produce pneumatic noise because this gap is bigger than normal.
The technical solution of the utility model is passed through for the thickness of blade 11 to be set to gradual change on air intake direction, so that
Blade 11 each position thermal deformation amount on air intake direction is variant, thus having buffering to the thermal deformation two of blade 11 entirety
Effect, blade 11 be difficult with the interior wall friction of jacket 20 and produce mechanicalness noise, also will not be with the inwall spacing of jacket 20
Bigger than normal and produce pneumatic noise, thus Noise Reduction is played to cabinet air-conditioner.
See figures.1.and.2, the thickness of blade 11 can be in first side 11a towards permissible on the direction of second side 11b
It is to arrange or first increase to reduce afterwards or first reduce in wave to increase afterwards.Here, considering waveform
Blade 11 can produce resistance to air draught, blade 11 thickness on first side 11a is towards the direction of second side 11b first
Unfavorable to the intensity of blade 11 after reduction, it is easily caused blade 11 and vibrate, in addition damaged.Therefore, in the present embodiment, described leaf
The thickness of piece 11 first increases on described first side 11a is towards the direction of described second side 11b and is kept to preferred embodiment afterwards.As
This, on the one hand, when air draught is blown into axial flow blower inside from first side 11a, blade 11 has guide effect to air-flow,
Windage substantially reduces；On the other hand, after air draught enters axial flow blower inside, because the thickness of blade 11 is in this blade 11
Middle part be gradually reduced towards on the direction of second side 11b again, so, air draught is more easy to flow out, and resistance reduces further.
With continued reference to Fig. 1 and Fig. 2, in a upper embodiment, in order to reduce the resistance to air draught for the blade 11, institute further
The cross section stating blade 11 is in that crescent is arranged towards on the direction of described second side 11b from described first side 11a.The moon presses
Blade 11 surface of shape setting is smoother, and, in smooth Surface runoff, resistance is less for air-flow.
Reference Fig. 4 to Fig. 6, also a kind of axial flow blower of this utility model, including jacket 20, and any of the above-described embodiment
Described wind wheel 10, described wind wheel 10 is installed in described jacket 20, the free end of described wind wheel 10 and described jacket 20
Inwall between spacing be 3mm～7mm.
Spacing between the inwall of wind wheel 10 and jacket 20 can not be too small nor excessive (concrete reason refer to above-mentioned
Content).In the present embodiment, verified by test of many times, when this spacing is in 3mm-7mm, even if the temperature in cabinet air-conditioner
Higher, the heat type amount of the inwall generation towards jacket 20 for the blade 11 is not more than 3mm, and blade 11 also will not be with jacket 20
Inwall rub.Even if the spacing between the inwall of blade 11 and jacket 20 be 7mm, when the temperature in cabinet air-conditioner relatively
When low, blade 11 shrinks, and the spacing between blade 11 and jacket 20 becomes big, is also unlikely to produce pneumatic noise.Here, wind wheel
Spacing between the inwall of 10 free end and described jacket 20 is 4mm～6mm is preferred embodiment.
With reference to Fig. 6, in order to reduce the resistance to air draught for the axial flow blower, in a preferred embodiment, described wind wheel 10
There is a wheel hub 12, one end of the air inlet towards described jacket 20 of described wheel hub 12 is provided with trouserss 50, described
Trouserss 50 described jacket 20 outlet air end towards the direction of air inlet on be in tapered setting.
Specifically, before setting trouserss 50, when air draught enters the air inlet of jacket 20, air-flow can be directly
The end face of impact wheel hub 12, and then lead to fraction to be obstructed, wheel hub 12 produces larger resistance to this fraction.Setting rectification
After cover 50, under the guide effect of trouserss 50, the outer wall along trouserss 50 enters along jacket 20 air-flow, it is to avoid air-flow is straight
Connect the end face impact with wheel hub 12, greatly reduce the resistance that air draught is subject to.
With continued reference to Fig. 6, in one embodiment, the wind of axial flow blower blowout is softer, and the outer wall of described trouserss 50 exists
It is in cambered outwards arc setting on the direction of the air inlet towards described jacket 20 for the outlet air end of described jacket 20.
So, when air draught blows over the outside wall surface of trouserss 50, near the air motion side of the outside wall surface of trouserss 50
To tangent with the outer wall of trouserss 50, therefore, this fraction can be transported towards between the inwall of trouserss 50 and jacket 20
Dynamic, and then make air draught mix homogeneously.Finally, the air velocity being blown out by axial flow blower is more homogeneous, and wind sense is softer.
With reference to Fig. 6, in a further preferred embodiment, equally, in order to reduce the resistance to air draught for the axial flow blower, described
Axial flow blower also includes being arranged at the wind-guiding stator blade 30 at the outlet air end of described jacket 20, described wind-guiding stator blade 30 towards institute
The one end stating the outlet air end of jacket 20 is provided with a kuppe 60, and described kuppe 60 is in the air inlet court of described jacket 20
It is in tapered setting on the direction of the outlet air end of described jacket 20.
Here, wind-guiding stator blade 30 1 aspect, to air draught rectification, can make the air-flow of blowout evenly；On the other hand,
Due to the backstop action by wind-guiding stator blade 30, effective air-out area of the outlet air end of jacket 20 is less, is equivalent to wind-guiding quiet
Leaf 30 is pressurized to air-flow, thus blowing farther by the air-flow that wind-guiding stator blade 30 is derived.But, air draught blows out from outlet air end
When, the direction of air-flow is not often named in a jumble, thus affecting the flow velocity of air-flow.After setting kuppe 60, air-flow can be along water conservancy diversion
The outer wall of cover 60 moves, and then can slow down the mixed and disorderly situation of airflow direction.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using this utility model description and accompanying drawing content
Change, or directly/be indirectly used in other related technical fields and be included in scope of patent protection of the present utility model.
