Therefore, the technical scheme of the utility model can ensure the miniaturization design of the air conditioner outdoor unit while improving the air quantity of the air conditioner outdoor unit.

It will be appreciated that when axial flow rotor 310 is in the operational position, the relative positions of axial flow rotor 310 and housing 100 enable axial flow rotor 310 to intake air from within mounting cavity 101 without directly from the external environment. Specifically, the casing 100 is provided with an air inlet structure 103, the heat exchanger 200 is arranged corresponding to the air inlet structure 103, and under the operation of the axial flow wind wheel 310, air in the external environment can enter the installation cavity 101 through the air inlet structure 103, and after exchanging heat with the heat exchanger 200, the air is discharged to the outdoor environment through the axial flow wind wheel 310.

Further, in this embodiment, the outdoor unit further includes a driving member mounted to the housing 100, and the driving member is drivingly connected to the wind wheel, so as to drive the axial flow wind wheel 310 to move between the working position and the initial position.

Of course, in other embodiments, the housing 100 may be provided with a manual driving structure, and the manual driving structure may be directly applied with force to drive the axial flow wind wheel 310 to axially move, or may be manually applied to the hub of the axial flow wind wheel to pull the axial flow wind wheel out of the installation cavity, or to press the axial flow wind wheel against the installation cavity, so as to switch between two positions.

Further, in the present embodiment, as shown in fig. 1 to 5, the driving member is configured as a first driving motor 320, and a transmission structure is provided between the first driving motor 320 and the axial flow wind wheel 310, and the transmission structure is configured to convert rotation of an output shaft of the first driving motor 320 into axial movement of the axial flow wind wheel 310, so that the axial flow wind wheel 310 can move between the working position and the initial position. In this embodiment, a motor is used as a driving member for driving the axial flow wind wheel 310, and when the first driving motor 320 runs, the output shaft rotates, and after the transmission conversion of the transmission structure, the axial flow wind wheel can be driven to move axially. The first driving motor 320 may be rotated forward, so as to drive the axial flow wind wheel 310 to move from the initial position to the working position, and the first driving motor 320 may be rotated backward, so as to drive the axial flow wind wheel 310 to move from the working position to the initial position. Of course, in other embodiments, the driving member may also be configured as a cylinder, and the output shaft of the cylinder may directly drive the axial flow wind wheel 310 to axially move.

Further, in the present embodiment, as shown in fig. 1 to 5, the transmission structure includes a transmission gear 410 and a transmission rack 420 that are meshed, the transmission gear 410 is fixedly connected to the output shaft of the first driving motor 320, and the transmission rack 420 extends along the axial direction of the axial flow wind wheel 310 and is relatively fixed to the axial flow wind wheel 310 in the axial direction of the axial flow wind wheel 310. When the output shaft of the first driving motor 320 rotates, the transmission gear 410 can be driven to coaxially rotate, and the transmission gear 410 and the transmission rack 420 are meshed for transmission, so that the transmission rack 420 moves along the extending direction relative to the transmission gear 410, and the axial flow wind wheel 310 is driven to move along the axial direction. Wherein, the fact that the driving rack 420 is relatively fixed to the axial flow wind wheel 310 in the axial direction of the axial flow wind wheel 310 means that the driving rack 420 and the axial flow wind wheel 310 are synchronous when moving in the axial direction, but when the axial flow wind wheel 310 rotates, the driving rack 420 is not driven to rotate, so that the driving rack 420 can be stably meshed with the driving gear 410, or the driving rack 420 is set to be a rotating shaft coaxially fixed with the axial flow wind wheel 310, and a plurality of annular tooth grooves which are distributed at intervals along the axial direction are arranged on the rotating shaft for the driving gear 410 to mesh, so that when the axial flow wind wheel 310 rotates, the driving rack 420 is driven to rotate, and the meshing of the driving gear 410 and the driving rack 420 is not influenced.

Of course, in other embodiments, the housing 100 may be provided with structure that cooperates with the axial flow rotor 310 to guide the axial flow rotor 310 to move axially.

After the driving rack 420 is driven by the driving gear 410 to move, the air guide piece 500 can be driven to move along the axial direction of the axial flow wind wheel 310, so that the second driving motor 330 is driven to move synchronously, and finally the axial flow wind wheel 310 can be driven to move axially, the second driving motor 330 can also be driven to rotate, and the air guide channel 511 arranged on the air guide piece 500 can guide air flow to flow from the air inlet side to the air outlet side of the axial flow wind wheel 310. So set up, wind-guiding piece 500, transmission rack 420 and second driving motor 330 and axial-flow gear's axial fixed in axial direction is favorable to axial-flow wind wheel 310's steady operation, and specifically, transmission rack 420's axial motion can steadily transmit axial-flow wind wheel 310, and wind-guiding channel 511 of wind-guiding piece 500 can steadily guide the air current flow direction, and second driving motor 330 can steadily drive axial-flow wind wheel 310 and rotate. Of course, in other embodiments, the avoiding port 102 may have a port wall extending along an axial direction of the axial flow wind wheel 310 to form an air guiding channel 511, where part of the axial flow wind wheel 310 protrudes out of the mounting cavity 101 in the working position, and part of the axial flow wind wheel 310 is accommodated in the air guiding channel 511, and the air guiding channel 511 may play a role of guiding airflow direction when the axial flow wind wheel 310 operates, and the driving rack 420 is fixedly connected to the housing 100 of the second driving motor 330, so that the second driving motor 330 and the axial flow wind wheel 310 can be driven to axially move.

When the axial-flow wind wheel 310 is in the working position, the end surface of the wind guiding ring 510 close to the fixing ring 520 is not higher than the outer surface of the casing 100, so that the wind guiding ring 510 can guide the axial-flow wind wheel 310 to enter the installation cavity 101. Specifically, the air passing space 531 is formed between the plurality of connection arms 530, and the air flow in the installation cavity 101 flows to the air passing space 531 through the space between the plurality of connection arms 530, and then flows to the air guide passage 511 in the air guide ring 510. In addition, the second driving motor 330 is installed on the fixing ring 520 through the first bracket 340, and a space for accommodating the second driving motor 330 is provided in the fixing ring 520, so that the second driving motor 330 can be partially accommodated in the fixing ring 520 and partially accommodated in the wind passing space 531, so as to reduce the volume of the second driving motor 330 exposed in the wind passing space 531, thereby avoiding the second driving motor 330 from blocking the air inlet of the axial flow wind wheel 310, and the casing 100 of the second driving motor 330 is further provided with a diversion slope on one side close to the wind guiding ring 510 to guide the airflow to flow towards the axial flow wind wheel 310. Further, the size of the fixing ring 520 is smaller than the size of the air guiding ring 510, so that the air volume of the air conditioner outdoor unit is improved by differentiating the sizes of the fixing ring 520 and the air guiding ring 510. Specifically, the size of the air guide ring 510 is designed to be larger, the axial flow wind wheel 310 which the air guide ring 510 can accommodate is also larger, and the air quantity of the axial flow wind wheel 310 is also larger; on the premise of meeting the requirement of the fixed installation of the second driving motor 330, the size of the fixing ring 520 is designed to be smaller, so that the space occupied by the fixing ring 520 in the installation cavity 101 can be reduced, and the blocking of the air flow during the air inlet of the axial flow wind wheel 310 can be reduced.

Further, in this embodiment, as shown in fig. 2 and 4, the mounting cavity 101 is further provided with a support member 130, a side of the support member 130 near the avoidance port 102 is configured as a ring shape, the fixing ring 520 is provided with a ring groove 521, and in the initial position, the support member 130 is inserted into the ring groove 521. In this way, when the axial flow wind wheel 310 is at the initial position, the fixing ring 520 can be stably matched with the supporting member 130 through the annular groove 521, the displacement of the wind guiding member 500 and the supporting member 130 is limited at the radial upper end of the axial flow wind wheel 310, and the engagement of the transmission gear 410 and the transmission rack 420 can be realized when the first driving motor 320 is stopped, the wind guiding member 500 and the housing 100 are limited at the axial upper end of the axial flow wind wheel 310, so that each part capable of moving relative to the housing 100 can be stably arranged in the mounting cavity 101 when the axial flow wind wheel 310 is at the initial position, and shaking and displacement of the parts can be avoided when the air conditioner outdoor unit is carried, transported and stored, and the matching failure is caused.

In this way, during operation of axial flow rotor 310, side 106 of housing 100 receives air and end 105 receives air, thereby shortening the flow path of the air flow from air intake structure 103 to axial flow rotor 310. In addition, when the air conditioner outdoor unit is operated, since the axial flow wind wheel 310 is in the working position and protrudes out of the outer surface of the shell 100, the heat exchanger 200 and the inner wall of the side 106 can be arranged at equal height, so that the heat exchange area of the heat exchanger 200 is increased, the heat exchange coefficient between the airflow and the surface of the heat exchanger 200 is improved, and the heat exchange performance of the air conditioner outdoor unit is improved. While the same heat exchange coefficient is ensured, the axial flow wind wheel 310 of the embodiment can operate at a lower rotation speed, which is beneficial to reducing the operation noise of the air conditioner outdoor unit.
