The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
The indoor unit of the air conditioner in the application refers to a part comprising an indoor fan and an indoor heat exchanger; the indoor fan is used for sucking air from an air inlet of the indoor unit of the air conditioner and blowing the air out of an air outlet of the indoor unit of the air conditioner after the air flows through the indoor heat exchanger; the indoor heat exchanger may function as a condenser or an evaporator, and the air conditioner may function as a heater in a heating mode when the indoor heat exchanger functions as the condenser, and as a cooler in a cooling mode when the indoor heat exchanger functions as the evaporator.
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides an air conditioner indoor unit, which includes a casing 1, a wind guide assembly 2, and a driving device 3; the casing 1 is provided with an air outlet 11, the air guide assembly 2 is arranged at the air outlet 11 and used for controlling the air outlet direction, and comprises a rotatable driving blade 21, and the driving blade 21 is provided with a shaft sleeve 211; the driving device 3 is used for driving the driving blade 21 to rotate, is arranged in the housing 1 and has a rotating shaft 31, the rotating shaft 31 includes an insertion section 311, and the insertion section 311 is inserted into the shaft hole 2111 of the shaft sleeve 211 to connect the driving device 3 and the driving blade 21 in a transmission manner; preferably, the driving device 3 is a motor.
Further, as shown in fig. 3 to 5, the cross section of the insertion section 311 of the rotating shaft 31 is polygonal, the shape of the shaft hole 2111 matches with the shape of the insertion section 311, and the side wall of the shaft sleeve 211 is provided with an opening 2112 for the insertion section 311 to enter and exit the shaft hole 2111. In this way, when the air guide assembly 2 is mounted, the rotating shaft 31 can enter the shaft hole 2111 from the opening 2112 along the radial direction of the shaft sleeve 211, and when the air guide assembly 2 is dismounted, the rotating shaft 31 can exit from the shaft hole 2111 through the opening 2112 along the radial direction of the shaft sleeve 211.
Based on the above structure, the air guiding assembly 2 can be assembled and disassembled along the radial direction of the rotating shaft 31, so that the air guiding assembly 2 can be directly installed on the driving device 3 from the outside of the air outlet 11 along the opposite direction of the air outlet direction, and can be disassembled from the driving device 3 along the air outlet direction, compared with the prior art that the operation is required to be carried out in the shell 1 along the axial direction of the rotating shaft 31, the assembling difficulty of the air guiding assembly 2 is greatly reduced, the assembling difficulty of the air conditioner indoor unit can be reduced, and the production efficiency of the air conditioner indoor unit can be improved; meanwhile, the internal space of the indoor unit of the air conditioner is optimized, and unnecessary disassembly and assembly space does not need to be reserved for the air guide assembly 2, so that the volume can be designed to be smaller, and a delicate and small shape can be obtained.
Since the cross section of the plug section 311 is polygonal, it has directivity when it enters the shaft hole 2111 from the opening 2112, and there is a case where it cannot enter because of misalignment. To solve this problem, as shown in fig. 6, in some embodiments, both side edges of the opening 2112 have a displacement difference L in the direction in which the opening 2112 faces.
Based on the above structure, as shown in fig. 7 to 9, in the process that the rotating shaft 31 enters the shaft hole 2111 through the opening 2112 along the radial direction of the shaft sleeve 211, the edge of the opening 2112 at the side farther from the center line of the shaft hole 2111 firstly corrects the rotating shaft 31 to rotate in one direction, then the edge of the opening 2112 at the side closer to the center line of the shaft hole 2111 corrects the rotating shaft 31 for the second time to rotate in the opposite direction, and finally, the inserting section 311 of the rotating shaft 31 enters the shaft hole 2111 in a posture matched with the shaft hole 2111. Therefore, whether the inserting section 311 is aligned with the shaft hole 2111 or not does not need to be considered when the air guide assembly 2 is installed, the installation difficulty is reduced, and the installation efficiency is improved.
Further, both side edges of the opening 2112 are provided with guide slopes 2113, and the two guide slopes 2113 gradually expand along a direction from inside the shaft hole 2111 to outside the shaft hole 2111. Thus, the guiding inclined surface 2113 can play a guiding role in the process that the rotating shaft 31 enters the shaft hole 2111 through the opening 2112 along the radial direction of the shaft sleeve 211, so that the rotating shaft 31 rotates, and the insertion section 311 of the rotating shaft can enter the shaft hole 2111 in a posture matched with the shaft hole 2111.
Alternatively, as shown in fig. 4 to 6, in some embodiments, in order to ensure that the torque transmission structure composed of the rotating shaft 31 and the shaft sleeve 211 can transmit larger torque without failure due to slipping, the cross section of the insertion section 311 of the rotating shaft 31 is a regular polygon, and the shape of the insertion section 311 and the shape of the shaft hole 2111 have the following relationship: the cross section of the insertion section 311 is a regular N-polygon, the axial hole 2111 has an N-side hole wall surface, and if N is an even number, N is 2N +2, and if N is an odd number, N is 2N + 1.
Optionally, as shown in fig. 2, in some embodiments, in order to enhance the wind guiding effect, the wind guiding assembly 2 further includes a rotatable driven blade 22, and the driven blade 22 is in transmission connection with the driving blade 21 through a connecting rod 23. Thus, under the driving of the driving device 3, the driving blade 21 and the driven blade 22 can rotate together, so as to achieve the effect of enhancing the wind guiding.
Alternatively, as shown in fig. 2, in some embodiments, to simplify the disassembling and assembling operation, the air guiding assembly 2 further includes a supporting plate frame 24, the driving blade 21 and the driven blade 22 are both rotatably disposed on the supporting plate frame 24, and the supporting plate frame 24 is detachably connected to the housing 1. Based on this, only need to place air guide component 2 outside air outlet 11, then push it to air outlet 11 inside, make the grafting section 311 of pivot 31 get into in shaft hole 2111, make supporting plate frame 24 be connected with casing 1 simultaneously, can accomplish air guide component 2's installation, simple and convenient and swift. Similarly, the air guide component 2 is also convenient and quick to disassemble.
Alternatively, as shown in fig. 2, in some embodiments, the driving device 3 is disposed at the lower edge of the air outlet 11, and the rotating shaft 31 is vertically upward; the air guide assembly 2 is arranged above the driving device 3, the driving blade 21 and the driven blade 22 are vertically arranged, and the shaft hole 2111 is arranged at the bottom of the driving blade 21. Thus, under the driving of the driving device 3, the driving blade 21 and the driven blade 22 can rotate left and right, and the transverse wind sweeping is realized.
