The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Hereinafter, a wind scooper for an air conditioner according to an embodiment of a first aspect of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 3, the air guide ring for an air conditioner according to the embodiment of the present invention includes a body 10, an air inlet end 11 and an air outlet end 12 are formed on the body 10, and at least one groove 13 circumferentially arranged along an inner circumferential wall of the body 10 is provided.
Therefore, according to the air guide ring for the air conditioner provided by the embodiment of the invention, the at least one groove 13 arranged along the circumferential direction of the body 10 is arranged on the inner circumferential wall of the body, the groove 13 can increase the local gap between the air guide ring and the axial flow fan blade, and the wind energy reflowing from the air outlet end 12 can enter the local gap and does not directly reflow to the air inlet end 11, so that the intensity of change of the wind speed is effectively relieved, the noise is reduced, meanwhile, the air reflowing from the air guide ring and the axial flow fan blade is correspondingly reduced, the reflow loss of the wind volume is reduced, and the air output of the air guide ring is ensured.
In the prior art, the structure of the wind guide ring is not changed, and the noise is reduced by arranging the bend on the outer edge of the axial flow fan blade. At this time, the load of the drive motor for driving the axial flow fan blade to rotate is increased, the used electric power is increased, and the efficiency is reduced. According to the air guide ring for the air conditioner, the noise can be reduced only by arranging the groove 13 on the inner peripheral wall of the air guide ring, the structure of the axial flow fan blade is not required to be changed, the noise is reduced, meanwhile, the load of the driving motor is relatively reduced, and the efficiency is relatively improved.
The structure of the groove 13 is not particularly limited as long as the requirements for reducing noise and not reducing the air volume are satisfied. Alternatively, according to one embodiment of the present invention, the groove 13 is formed as an annular groove extending in the circumferential direction of the body 10. In other words, the annular groove is formed in the inner peripheral wall of the body 10, and a circular local gap can be formed between the inner peripheral wall of the body 10 and the axial flow fan blade, so that the intensity of change of the wind speed around the circumferential direction of the axial flow fan blade can be reduced, and the noise is reduced.
The number of the grooves 13 is not particularly limited, and according to an embodiment of the present invention, there is one groove 13, and the depth of the groove 13 is gradually reduced from the air inlet end 11 to the air outlet end 12. That is, a groove 13 is formed on the inner peripheral wall of the body 10, and the depth of the groove 13 gradually increases from the air outlet end 12 to the air inlet end 11. At this time, the air flowing back from the air outlet end 12 can enter the grooves 13 with the increasing depth in sequence, so that the intensity of the change of the air speed is effectively relieved, and the noise reduction effect is good. Meanwhile, the side wall of the groove 13 can also prevent the part of the backflow wind from entering a leeward surface, so that the loss of the wind quantity is reduced.
In other embodiments of the present invention, the groove 13 includes a plurality of grooves, and in particular, the groove 13 may include 3 to 6 grooves, each groove 13 has the same depth, and the plurality of grooves 13 are spaced apart along the axial direction of the body 10, wherein each two adjacent grooves 13 are spaced apart by the same distance. In other words, the grooves 13 are uniformly formed on the inner circumferential wall of the body 10, so that the wind speed is changed more uniformly, the noise reduction effect is further improved, and the grooves 13 also play a role in reducing the loss of the wind volume.
Of course, the distance between the grooves 13 may also be different. For example, according to an embodiment of the present invention, the grooves 13 include a plurality of grooves 13, the plurality of grooves 13 are continuously arranged along the axial direction of the body 10, the depth of the plurality of grooves 13 gradually decreases from the air inlet end 11 to the air outlet end 12, and further, the depth of the plurality of grooves 13 is not equal to form a step-like distribution in the direction from the air inlet end 11 to the air outlet end 12.
Specifically, as shown in fig. 3, a plurality of grooves 13 are formed on the inner peripheral wall of the body 10, the plurality of grooves 13 are continuously arranged in the direction from the air inlet end 11 to the air outlet end 12, and the depth of each groove 13 is gradually reduced from the air inlet end 11 to the air outlet end 12, that is, the depth of each groove 13 is gradually increased from the air outlet end 12 to the air inlet end 11 of the body 10, and the air flowing back from the air outlet end 12 sequentially enters the grooves with the gradually increasing depth, so that the intensity of the change of the air speed is effectively relieved, the noise reduction effect is better, and the structure further blocks the air flowing back from the gap, thereby reducing the air loss and improving the air outlet volume.
The air conditioner according to the second aspect of the invention comprises the wind guide ring for the air conditioner according to the above embodiment. Since the air guide ring for the air conditioner according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the air conditioner according to the embodiment of the present invention also has corresponding technical effects. Namely: the air quantity loss of the air guide ring can be reduced as much as possible, the noise is reduced, the heat exchange efficiency of the outdoor unit of the air conditioner is improved, the air guide ring is improved, the normal operation of the blades cannot be influenced, and the improvement is convenient.
Other configurations and operations of the air conditioner according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein.
