It will describe in detail below to the structure of counter-rotating fan 130.
Please continue to refer to Fig. 1 and Fig. 2, it is based on above-mentioned any one embodiment, for the structure of counter-rotating fan 130, to whirlwind
Machine 130 includes mounting base 131, the first axial-flow leaf 132a, the two the first axial-flow leaf and first motor 133a, wherein the
One axial-flow leaf 132a is installed on mounting base 131, and connect with first motor 133a；Second axial-flow leaf 132b rotationally pacifies
Loaded on mounting base 131, and it is located at the front side of the first axial-flow leaf 132a.
Specifically, mounting base 131 includes mounting cylinder, the first support and second support being arranged in mounting cylinder；Wherein,
The mounting cylinder is the tubular structure of both ends open, can blow out forward outlet air air accumulation, extends air supplying distance；First axle stream
Fan blade 132a is mounted in the first support, and the second axial-flow leaf 132b is mounted in the second support.Described first
It is integrally formed in frame and second support and the mounting cylinder, or is installed to mounting cylinder by mounting structures such as screw or buckles
It is interior.Any one in the first support and second support can be arranged in linear type, be also possible to be arranged in cross, or
The setting of person's Y-shaped, only need to guarantee it with preferable stability.First axial-flow leaf 132a and the second axial-flow leaf
The center of 132b is located substantially on same axis direction.
Fig. 1 and Fig. 2 are please referred to, for the first axial-flow leaf 132a, the first axial-flow leaf 132a is by first motor
133a driving rotation.For the second axial-flow leaf 132b, since the second axial-flow leaf 132b is installed in rotation on installation
On seat 131, therefore, the first driving method are as follows: the second axial-flow leaf 132b is rotated by other motor drivens, the motor driven the
Two axial-flow leaf 132b and the first axial-flow leaf 132a rotate in the opposite direction, and outlet air air is blown axially forward along it
Out, air supplying distance can so be extended.Second of driving method are as follows: the second axial-flow leaf 132b passes through reverse drive structure and first
Axial-flow leaf 132a connection, to drive the second axial-flow leaf 132b rotation by the first axial-flow leaf 132a.The third driving side
Formula are as follows: the second axial-flow leaf 132b rotates generated air stream drives by the first axial-flow leaf 132a and rotates, at this time the second axis stream
The direction of rotation of fan blade 132b is consistent with the direction of rotation of the first axial-flow leaf 132a.Latter two driving method can save motor at
Originally it and is worked by motor and generates noise.These three driving methods can accordingly be chosen according to demand, and specifically there are also in detail below
It is thin to introduce.
Please refer to Fig. 1 and Fig. 2, it is contemplated that air conditioner 100 is led air-flow with the first axial-flow leaf 132a when executing air-supply
For direction of rotation when leading to the air outlet is clockwise, at this point, under the action of the first axial-flow leaf 132a, it is external empty
Gas passes through heat exchanger 140 and flows to the front of first axle stream fan blade 132a, air-flow have rotation function along clockwise direction and
Axial kinetic energy in the first axial-flow leaf 132a axial direction.If the second axial-flow leaf 132b when actively blowing forward, turn
Dynamic direction is consistent with the rotation direction of the first axial-flow leaf 132a, then finally the air-flow as derived from the second axial-flow leaf 132b has
There is higher rotation function, in this way, will lead to air supplying distance shortening.
In consideration of it, in the present embodiment, the first axial-flow leaf 132a is consistent with the axis direction of the second axial-flow leaf 132b,
Also, air-flow is oriented to the direction of rotation when outlet air end by the first axial-flow leaf 132a by the rotation center, with the second axis
Direction of rotation when air-flow is oriented to the outlet air end by stream fan blade 132b by the rotation center is opposite.In this way, being located at two axial flow
When air-flow between wind wheel is flowed out from the second axial-flow leaf 132b, most rotation functions can be converted into axial kinetic energy, such as
This, air supplying distance is with regard to farther.
Fig. 1 and Fig. 2 are please referred to, it is herein preferably, right for the driving method that the second axial-flow leaf 132b of driving is reversely rotated
Cyclone cluster 130 further includes that the second motor 133b, the second axial-flow leaf 132b connecting with the second axial-flow leaf 132b passes through second
Motor 133b driving rotation.Revolving speed when first motor 133a and the second motor 133b works may be the same or different.Example
Such as, when controlling first motor 133a and the second motor 133b work at the same time, the revolving speed of first motor 133a can be greater than second
The revolving speed of motor 133b is also possible to revolving speed of the revolving speed less than the second motor 133b of first motor 133a, is also possible to when control
When making two decelerating through motor operations, the revolving speed of one of motor is decelerated to 0.
Obviously, by adjusting the revolving speed of first motor 133a and the second motor 133b (that is, the first axial-flow leaf
The revolving speed of 132a and the second axial-flow leaf 132b), the air supplying distance of Lai Shixian counter-rotating fan 130 increases or decreases, to mention
The high blowing range of air conditioner 100.For example, when the air conditioner 100 operation, the first axial-flow leaf 132a rotation, by air-flow
It is imported in shell 110 from air inlet 10, and is oriented to the front of the first axial-flow leaf 132a.At this point, if necessary to increase air-supply away from
From the revolving speed of the second axial-flow leaf 132b can be increased.If necessary to reduce air supplying distance, the second axial-flow leaf can be reduced
The revolving speed of 132b perhaps stops the second axial-flow leaf 132b operating or control the second axial-flow leaf 132b reversion (relative to the
Direction of rotation when two axial-flow leaf 132b blow).Certainly, in order to adjust air supplying distance, first axle stream can also be adjusted simultaneously
The revolving speed of fan blade 132a and the second axial-flow leaf 132b, for example, increasing the first axial-flow leaf 132a and the second axial-flow leaf simultaneously
The revolving speed of 132b；Also it can reduce the revolving speed of the first axial-flow leaf 132a, and increase the revolving speed of the second axial-flow leaf 132b；May be used also
To reduce the revolving speed of the first axial-flow leaf 132a and the revolving speed of the second axial-flow leaf 132b simultaneously；First axle stream wind can also be increased
The revolving speed of leaf 132a reduces the revolving speed of the second axial-flow leaf 132b.
But if the revolving speed of first motor 133a is identical greater than the revolving speed of the second motor 133b, the first axial-flow leaf
Generated rotation function can be superimposed when 132a and the second axial-flow leaf 132b rotation, and axial kinetic energy is reduced, so that outlet air
Amount is reduced.To avoid such case, it is preferable that the revolving speed of the revolving speed of first motor 133a and the second motor 133b are different.
In this way, can avoid generated rotation function superposition when the first axial-flow leaf 132a and the second axial-flow leaf 132b rotates, it will be exhausted
Most of rotation function can be converted into axial kinetic energy, substantially improve the air output of gentle breeze sense, the gentle breeze sense comfort level of raising.Especially
Ground, in view of first motor 133a as main driving device, it is preferable that the revolving speed of first motor 133a is greater than the second motor 133b
Revolving speed.
Fig. 1 and Fig. 2 are please referred to, certainly, the driving method that the second axial-flow leaf 132b of driving is reversely rotated is not limited to
This, in other embodiments, counter-rotating fan 130 includes reverse drive structure, and first motor 133a has motor shaft, motor shaft
One end connects the first axial-flow leaf 132a, and the other end of motor shaft connects the second axial-flow leaf 132b by being driven in the reverse direction structure,
To drive the second axial-flow leaf by reverse drive structure when first motor 133a drives the first axial-flow leaf 132a rotation
132b is rotated backward.By reverse drive structure, the use of motor can be reduced, and then reduces cost and as caused by motor
Noise.It is relatively conventional in machinery field as reverse drive structure specific structure, it does not lift in detail one by one herein.
