[0031] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0032] The following is based on Figures 1-10 This invention describes an embodiment of an air conditioner outdoor unit 100.

[0033] According to an embodiment of the present invention, the outdoor unit 100 of the air conditioner includes a casing 10, a compressor 20, an outdoor heat exchanger 30, and an outdoor fan 40. The casing 10 is provided with an air inlet 11 and an air outlet 12. Outdoor air enters the outdoor unit 100 of the air conditioner through the air inlet 11. After entering the outdoor unit 100, the outdoor air can exchange heat with the outdoor heat exchanger 30 to change the temperature of the refrigerant in the outdoor heat exchanger 30.

[0034] According to an embodiment of the present invention, the outdoor unit 100 of the air conditioner further includes a refrigerant circulation loop, an outdoor fan 40, a power consumption sensor, and a controller.

[0035] In an embodiment of this utility model, the air conditioner includes an outdoor unit 100 and an indoor unit. The refrigerant circulation loop of the air conditioner consists of a compressor 20, a condenser, an expansion valve, and an evaporator. The refrigerant circulates between the compressor 20, the condenser, the expansion valve, and the evaporator, thereby forming a refrigerant circulation loop.

[0036] The compressor 20 compresses the low-temperature, low-pressure refrigerant into a high-temperature, high-pressure refrigerant. This heat can be exchanged with indoor air to heat the indoor air, or with outdoor air to cool the indoor air. In addition, the compressor 20 provides power for the circulation of the refrigerant.

[0037] One of the condensers and evaporator is the outdoor heat exchanger 30, and the other is the indoor heat exchanger. When the refrigerant enters the outdoor heat exchanger 30, it exchanges heat with the outdoor air. When the refrigerant enters the indoor heat exchanger, it exchanges heat with the indoor air.

[0038] When the air conditioner is in cooling mode, heat in the outdoor heat exchanger 30 is transferred from the refrigerant to the outdoor air, and heat in the indoor heat exchanger is transferred from the indoor air to the refrigerant. This allows the refrigerant to dissipate indoor heat to the outdoor environment, thereby lowering the indoor temperature.

[0039] When the air conditioner is in heating mode, heat is transferred from the outdoor air to the refrigerant in the outdoor heat exchanger 30, and heat is transferred from the refrigerant to the indoor air in the indoor heat exchanger. This allows the refrigerant to absorb heat from the outdoor environment and transfer the heat to the indoor environment, thereby raising the indoor temperature.

[0040] An expansion valve can change the pressure of the refrigerant in the refrigerant circulation loop. By throttling and reducing pressure, the expansion valve converts the medium-temperature, high-pressure liquid refrigerant into low-temperature, low-pressure wet vapor, which then absorbs heat in the evaporator to achieve a cooling effect.

[0041] Furthermore, the expansion valve can automatically adjust the flow rate based on the superheat of the gaseous refrigerant at the evaporator outlet, maintaining a stable indoor temperature and meeting the requirements of refrigerant circulation. More importantly, the expansion valve can prevent liquid refrigerant from entering the compressor 20, avoiding liquid hammer and protecting the compressor 20 from damage.

[0042] The fan assembly is used to drive indoor air into the indoor unit of the air conditioner by rotation, and the air passes through the indoor heat exchanger to exchange heat between the refrigerant and the indoor air. The fan assembly accelerates the flow of indoor air to the indoor heat exchanger, thereby speeding up the heat exchange between the indoor air and the refrigerant.

[0043] The outdoor fan 40 is used to drive outdoor air through the outdoor heat exchanger 30 by rotation, so that the refrigerant and the outdoor air can exchange heat. Under the action of the outdoor fan 40, the flow of outdoor air to the outdoor heat exchanger 30 can be accelerated, thereby accelerating the heat exchange between the outdoor air and the refrigerant. Finally, the air that has undergone heat exchange can be blown into the room through the air outlet 12.

[0044] A refrigerant pipe connects the outdoor heat exchanger 30 and the compressor 20. The refrigerant pipe is used to transfer the refrigerant between the compressor 20 and the outdoor heat exchanger 30, so as to realize the transfer of heat between the compressor 20 and the outdoor heat exchanger 30.

[0045] Furthermore, in the embodiments of this utility model, the outdoor unit 100 of the air conditioner includes, but is not limited to, a top-discharge type outdoor unit 100 of the air conditioner, with the air inlet 11 disposed on the circumferential side wall of the casing 10 and the air outlet 12 located at the top of the casing 10.

[0046] Specifically, when the outdoor unit 100 of the top-discharge air conditioner is running, outdoor air enters the outdoor unit 100 through the air inlet 11 provided on the circumferential side wall of the casing 10 under the action of the outdoor fan 40. This allows the outdoor air to flow directly to the outdoor heat exchanger 30, so that the outdoor air can directly exchange heat with the outdoor heat exchanger 30. The outdoor heat exchanger 30 is arranged circumferentially along the inner wall of the casing 10. This makes the structure of the outdoor unit 100 more compact and helps to improve the space utilization rate inside the casing 10. With this arrangement, the flow path of outdoor air in the outdoor unit 100 is shorter, and the heat exchange is more sufficient, thereby improving the working efficiency of the outdoor unit 100.

[0047] Furthermore, the housing 10 in this embodiment of the present invention also includes a main housing 13 and a front cover 14.

[0048] Furthermore, an air inlet 11 is provided on the main casing 13, so that outdoor air can enter the outdoor unit 100 of the air conditioner through the air inlet 11 to exchange heat with the outdoor heat exchanger 30 installed in the main casing 13, thereby realizing the heat exchange between the outdoor environment and the refrigerant of the air conditioner.

[0049] Furthermore, the main housing 13 also includes a mesh cover that covers the air inlet 11 on the main housing 13. This can filter the outdoor air entering the outdoor unit 100 of the air conditioner through the air inlet 11 to reduce dust entering the outdoor unit 100 of the air conditioner, thereby reducing dust accumulation inside the outdoor unit 100 of the air conditioner. In addition, the mesh cover also has the function of preventing rodents and insects, which can prevent large organisms from entering the outdoor unit 100 of the air conditioner and causing the outdoor fan 40 to jam or produce abnormal noise.

[0050] To facilitate cleaning of the mesh cover, during installation, the circumferential edge of the mesh cover is directly pressed onto the chassis and main housing 13.

[0051] Furthermore, the front side of the main housing 13 is at least partially open to facilitate the installation of other structural components within the main housing 13.

[0052] Furthermore, the front cover 14 is provided on the open portion at the front of the main housing 13 to close the open portion at the front of the main housing 13, so as to protect the safety of the structural components inside the main housing 13.

[0053] Furthermore, the outdoor heat exchanger 30 is arc-shaped, and its front side is at least partially open. Specifically, in the top-discharge air conditioner outdoor unit 100, the outdoor heat exchanger 30 is arranged in an arc shape, which allows for the placement of a larger outdoor heat exchanger 30 in the top-discharge air conditioner outdoor unit 100, thereby improving the outdoor heat exchange efficiency of the air conditioner outdoor unit 100. The front side of the outdoor heat exchanger 30 is also at least partially open to accommodate other structural components in the air conditioner outdoor unit 100.

[0054] Furthermore, the front cover 14 corresponds at least partially to the open side of the outdoor heat exchanger 30, so that the front cover 14 can close the open side of the outdoor heat exchanger 30. This not only ensures the reliability of the outdoor heat exchanger 30 in the housing 10, but also prevents the heat exchange airflow from flowing out of the housing 10. The heat exchange airflow can flow between the outdoor heat exchanger 30 and the front cover 14.

[0055] Furthermore, an arc-shaped air guide groove 1411 is provided on the side of the front cover 14 facing the inside of the housing 10, corresponding to the outdoor heat exchanger 30. The opening of the arc-shaped air guide groove 1411 faces the outdoor heat exchanger 30 and defines an annular air guide channel between it and the outdoor heat exchanger 30.

[0056] Specifically, the arc-shaped air guide slot 1411 is also arc-shaped. When the airflow flows from the outdoor heat exchanger 30 to the front cover 14, it can enter the arc-shaped air guide slot 1411 and continue to flow in an arc. Compared with the straight plate inner side plate of the front cover 14 in the prior art, the airflow in the annular air guide channel in this embodiment is stable and will not cause obvious step differences in the circumferential flow of the airflow. In this way, the impact of the airflow on the front cover 14 can be reduced, which can make the airflow in the housing 10 smoother and reduce the noise of the airflow in the housing 10.

[0057] Therefore, this embodiment of the utility model provides an arc-shaped air guide groove 1411 on the front cover 14 so that the arc-shaped air guide groove 1411 and the arc-shaped outdoor heat exchanger 30 together define an annular air guide channel. This can guide the airflow of the outdoor fan 40, make the airflow in the casing 10 smoother, and reduce the noise of the airflow in the casing 10.

[0058] Combination Figure 3 , Figure 6 and Figure 7 As shown, the outdoor fan 40 is located in the air duct and corresponds to the upper side of the outdoor heat exchanger 30. The arc-shaped air guide slot 1411 is located on the upper side of the front cover 14 and corresponds to the outdoor fan 40.

[0059] Specifically, in embodiments of this invention, the outdoor fan 40 includes, but is not limited to, a cross-flow fan. The cross-flow fan is located in the air guide channel, which creates negative pressure in the air guide channel to drive airflow within it.

[0060] Furthermore, the outdoor fan 40 corresponds to the upper side of the outdoor heat exchanger 30, which can drive the heat exchange airflow around the outdoor heat exchanger 30 to flow upward, so that the heat exchange airflow flows to the air outlet 12 at the top of the casing 10.

[0061] Furthermore, after the air enters the outdoor unit 100 of the air conditioner through the air inlet 11, it exchanges heat with the outdoor heat exchanger 30. In the outdoor unit 100, the airflow flows around the circumference of the outdoor unit 100. The front side of the outdoor heat exchanger 30 is open, and the arc-shaped air guide slot 1411 is located on the front cover 14.

[0062] In this way, when the airflow reaches the open part at the front of the outdoor heat exchanger 30, it can flow along the arc-shaped air guide groove 1411 on the front cover 14, so that the heat exchange airflow continues to flow circumferentially at the front of the outdoor heat exchanger 30. This can prevent the heat exchange airflow from suddenly changing direction and causing a step difference, thereby ensuring the smoothness of the heat exchange airflow in the outdoor unit 100 of the air conditioner. It can effectively reduce the turbulence and noise generated by the heat exchange airflow in the top-discharge outdoor unit 100 of the air conditioner.

[0063] Combination Figures 4-7 As shown, the front cover 14 includes a plate 141 and a cover 142. The plate 141 is disposed in the open portion on the front side of the main housing 13, and the cover 142 covers the front side of the plate 141.

[0064] Specifically, the front cover 14 is located on the front side of the main housing 13. The plate 141 of the front cover 14 is located in the open portion on the front side of the main housing 13 to cover the front side of the main housing 13. This can prevent air leakage on the front side of the main housing 13 and ensure the structural integrity of the outdoor unit 100 of the air conditioner.

[0065] Furthermore, the cover 142 is placed on the front side of the plate 141 and defines an accommodating space between the cover 142 and the plate 141. In this way, the electrical control box 60 is placed in the accommodating space and connected to the plate 141. This not only ensures the stability of the electrical control box 60 in the outdoor unit 100 of the air conditioner, but also allows the cover 142 to protect the electrical control box 60, preventing water and dust from entering the electrical control box 60. This ensures the normal operation of the electrical control box 60.

[0066] Furthermore, the arc-shaped air guide slot 1411 is formed on the plate 141, so that the opening of the arc-shaped air guide slot 1411 faces the outdoor heat exchanger 30. The arc-shaped air guide slot is set on the plate 141, so that the plate 141 provides a stable and reliable setting position for the arc-shaped air guide slot 1411, thereby ensuring the setting stability of the arc-shaped air guide slot 1411 in the outdoor unit 100 of the air conditioner. In this way, the structural reliability of the air guide channel can be guaranteed, so as to prevent the airflow from having a step difference and generating turbulence when it flows to the open position at the front of the outdoor heat exchanger 30. This can ensure the stability of the circumferential flow of the airflow.

[0067] Combination Figures 5-7 As shown, at least one end of the plate 141 corresponding to the arc-shaped air guide 1411 in the left and right directions is also provided with a connecting plate segment 1412 extending in the left and right directions, and the connecting plate segment 1412 is connected to the outdoor heat exchanger 30.

[0068] Specifically, the arc-shaped air guide groove 1411 on the plate 141 and the outdoor heat exchanger 30 together define the air guide channel. The plate 141 is located at the open front end of the outdoor heat exchanger 30. Therefore, the left and right ends of the plate 141 are connected to the left and right ends of the outdoor heat exchanger 30 to form a complete circumferential air guide channel in the outdoor unit 100 of the air conditioner.

[0069] Furthermore, a connecting plate segment 1412 is provided at least one end of the plate 141 in the left and right directions. The connecting plate segment 1412 extends in the left and right directions, which increases the connection area between the plate 141 and the outdoor heat exchanger 30. This helps to strengthen the connection reliability between the plate 141 and the outdoor heat exchanger 30, thus ensuring the connection strength between the plate 141 and the outdoor heat exchanger 30 and ensuring the structural reliability of the air guide channel. This also prevents the airflow from impacting the plate 141 in the air guide channel, causing the plate 141 to vibrate and generate noise.

[0070] Combination Figures 5-7 As shown, the plate body 141 is provided with connecting plate segments 1412 at both ends of the arc-shaped air guide groove 1411 in the left and right directions.

[0071] Specifically, the arc-shaped air guide groove 1411 on the plate 141, together with the outdoor heat exchanger 30, defines a complete circumferential air guide channel. To ensure the reliability of airflow in the air guide channel and prevent air leakage, in this embodiment of the invention, connecting plate segments 1412 are provided at both the left and right ends of the plate 141, and the connecting plate segments 1412 at both ends of the plate 141 extend in the left and right directions. This increases the connection area between the left and right ends of the plate 141 and the outdoor heat exchanger 30, thus ensuring the reliability of the connection between the left and right ends of the plate 141 and the outdoor heat exchanger 30, and thus ensuring the structural reliability of the air guide channel in the outdoor unit 100 of the air conditioner.

[0072] Furthermore, the connecting plate segments 1412 at both ends of the plate 141 are all set to correspond to the arc-shaped air guide grooves 1411. This allows the connection positions of the connecting plate segments 1412 and the outdoor heat exchanger 30 to correspond to the left and right sides of the arc-shaped air guide grooves 1411, thereby enhancing the structural reliability of the arc-shaped air guide grooves 1411 in the air guide channel. The heat exchange airflow mainly flows in the air guide channel, which can reduce the vibration of the plate 141 caused by the airflow impacting the plate 141, thereby helping to reduce the noise generated between the outdoor heat exchanger 30 and the plate 141.

[0073] Combination Figure 5 and Figure 6 As shown, the dimension of the portion of plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is greater than the sum of the dimensions of the portions of plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction.

[0074] Specifically, in the embodiments of this utility model, the plane perpendicular to the vertical direction is set as the horizontal plane, and the part of the plate 141 corresponding to the arc-shaped air guide groove 1411 should have the largest dimension in the left and right direction. This is to make the projection of the air guide channel defined by the arc-shaped air guide groove 1411 and the outdoor heat exchanger 30 on the horizontal plane approximately circular. In this way, the continuity of the air guide channel can be improved, so as to reduce the loss of heat exchange airflow in the air guide channel, thereby helping to improve the heat exchange efficiency of the outdoor unit 100 of the air conditioner.

[0075] Combination Figure 5 and Figure 6 As shown, the left-right dimension of the part of the plate 141 corresponding to the arc-shaped air guide groove 1411 is set as a, and the left-right dimension of the part of the plate 141 corresponding to the two connecting plate segments 1412 is set as b. a and b satisfy the relationship: 0.45≤b / a≤0.7.

[0076] According to some embodiments of this utility model, the dimension of the part of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is set as a, and the sum of the dimensions of the part of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction is set as b. a and b satisfy the relationship: b / a≥0.45.

[0077] Specifically, in the embodiments of this utility model, the ratio between the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction cannot be too small. If the ratio between the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is too small, then the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction will be too small, and the dimension of the portion of the plate 141 corresponding to the connection with the outdoor heat exchanger 30 in the left-right direction will be too large. This will cause the air guide channel defined by the arc-shaped air guide groove 1411 and the outdoor heat exchanger 30 to be discontinuous, and will cause a step difference when the heat exchange airflow flows from the outdoor heat exchanger 30 to the arc-shaped air guide groove 1411, thereby generating noise.

[0078] To improve the continuity between the arc-shaped air guide slot 1411 and the airflow channel defined by the outdoor heat exchanger 30, the ratio between the sum of the dimensions in the left-right direction of the portion of the plate 141 corresponding to the two connecting plate segments 1412 and the dimension in the left-right direction of the portion of the plate 141 corresponding to the arc-shaped air guide slot 1411 should not be less than a first preset value. The first preset value includes, but is not limited to, 0.44, 0.45, and 0.46.

[0079] According to some other embodiments of the present invention, the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is set as a, and the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction is set as b, and a and b satisfy the relationship: b / a≤0.7.

[0080] Specifically, in the embodiments of this utility model, the ratio between the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction should not be too large. If the ratio between the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is too large, then the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction will be too large, and the dimension of the portion of the plate 141 corresponding to the connection with the outdoor heat exchanger 30 in the left-right direction will be too small. This will reduce the connection portion between the connecting plate segment 1412 and the outdoor heat exchanger 30, reduce the connection strength between the connecting plate segment 1412 and the outdoor heat exchanger 30, and thus affect the connection reliability between the plate 141 and the outdoor heat exchanger 30, thereby reducing the reliability of the air guide channel.

[0081] To ensure the reliability of the airflow channel defined by the arc-shaped air guide slot 1411 and the outdoor heat exchanger 30, the ratio between the sum of the dimensions of the portions of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide slot 1411 in the left-right direction must not exceed a second preset value. The first preset value includes, but is not limited to, 0.69, 0.70, and 0.71.

[0082] According to some embodiments of the present invention, the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide groove 1411 in the left-right direction is set as a, and the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left-right direction is set as b. a and b satisfy the relationship: 0.45≤b / a≤0.7.

[0083] Specifically, the ratio between the sum of the dimensions of the portion of the plate 141 corresponding to the two connecting plate segments 1412 in the left and right directions and the dimension of the portion of the plate 141 corresponding to the arc-shaped air guide slot 1411 in the left and right directions is not less than 0.45 and not greater than 0.7. This not only improves the continuity between the arc-shaped air guide slot 1411 and the air guide channel defined by the outdoor heat exchanger 30, but also ensures the reliability of the arc-shaped air guide slot 1411 and the air guide channel defined by the outdoor heat exchanger 30.

[0084] Combination Figure 6 , Figure 7 and Figure 10As shown, the connecting plate segment 1412 has a first through hole 14121, and the outdoor heat exchanger 30 has a second through hole 321. The first through hole 14121 and the second through hole 321 correspond to each other and are connected by fasteners 50.

[0085] Specifically, the first perforation 14121 has a simple structure, making it easy to machine and install on the connecting plate segment 1412. The second perforation 321 also has a simple structure, making it easy to machine and install on the outdoor heat exchanger 30. This facilitates the manufacturing of the connecting plate segment 1412 and the outdoor heat exchanger 30, thereby improving the manufacturing convenience of the outdoor unit 100 of the air conditioner.

[0086] Furthermore, when installing the plate 141 and the outdoor heat exchanger 30, the first through hole 14121 on the connecting plate segment 1412 is aligned with the second through hole 321 on the outdoor heat exchanger 30, and then the fastener 50 is passed through the first through hole 14121 and the second through hole 321 in sequence to securely connect the first through hole 14121 and the second through hole 321. In this way, the plate 141 and the outdoor heat exchanger 30 can be connected and fixed, which is convenient to operate and reliable. This setting not only simplifies the connection operation of the plate 141 and the outdoor heat exchanger 30, but also ensures the connection strength between the plate 141 and the outdoor heat exchanger 30.

[0087] Combination Figure 9 and Figure 10 As shown, the outdoor heat exchanger 30 includes: The heat exchanger body 31 is arc-shaped and at least partially open on the front side.

[0088] Specifically, the heat exchanger body 31 is a structure in the refrigerant circulation loop of the outdoor unit 100 of the air conditioner. The heat exchanger body 31 contains flowing refrigerant so that outdoor air enters the outdoor unit 100 of the air conditioner and exchanges heat with the heat exchanger body 31, thereby realizing the heat transfer in the outdoor unit 100 of the air conditioner.

[0089] Furthermore, the heat exchange body 31 is arc-shaped so that it is suitable for installation in the outdoor unit 100 of the top-discharge air conditioner, and so that the heat exchange body 31 is fitted to the main casing 13 to improve the structural compactness of the heat exchange body 31 in the outdoor unit 100 of the air conditioner.

[0090] Furthermore, the front side of the heat exchange body 31 is at least partially open, so that a plate 141 is provided on the front side of the heat exchange body 31, and the plate 141 and the heat exchange body 31 together define the air guide channel in the outdoor unit 100 of the air conditioner.

[0091] End plate 32 is disposed on both sides of the heat exchange body 31 in the circumferential direction, and second perforation 321 is opened in end plate 32.

[0092] Specifically, the front side of the heat exchanger body 31 is at least partially open, that is, both circumferential sides of the end plate 32 are facing the front. The end plate 32 is located on both circumferential sides of the heat exchanger body 31. In this way, the end plate 32 can be close to the connecting plate segment 1412 on the plate body 141 located on the front side of the heat exchanger body 31. A second through hole 321 is provided on the end plate 32 so that the second through hole 321 is adjacent to the first through hole 14121 on the connecting plate segment 1412. This facilitates the correspondence between the first through hole 14121 and the second through hole 321, so that the fastener 50 can connect and fix the first through hole 14121 and the second through hole 321. In this way, not only can the connection between the plate body 141 and the outdoor heat exchanger 30 be improved, but also the connection reliability between the plate body 141 and the outdoor heat exchanger 30 can be improved.

[0093] Combination Figure 4 As shown, an electrical control box 60 is provided inside the front cover 14. The electrical control box 60 is connected to the plate 141 and is located below the arc-shaped air guide slot 1411.

[0094] Specifically, the outdoor unit 100 of the air conditioner also includes an electrical control box 60, which contains a control chip to realize the control function of the outdoor unit 100 of the air conditioner.

[0095] Furthermore, the control box 60 is connected to the board 141, which allows the board 141 to provide a stable and reliable installation position for the control box 60, thereby ensuring the structural stability of the control box 60 in the outdoor unit 100 of the air conditioner.

[0096] Furthermore, the electrical control box 60 is positioned on the plate 141 below the arc-shaped air guide slot 1411. This arrangement allows the electrical control box 60 to avoid the arc-shaped air guide slot 1411, ensuring the smooth flow of heat exchange airflow within the air guide channel jointly defined by the arc-shaped air guide slot 1411 and the outdoor heat exchanger 30. This prevents the heat exchange airflow from impacting the electrical control box 60 within the air guide channel, thus reducing noise generated by the heat exchange airflow within the air guide channel.

[0097] According to an embodiment of the present invention, the arc-shaped air guide groove 1411 includes a first air guide groove 14111 and a second air guide groove 14112. The first air guide groove 14111 and the second air guide groove 14112 are spaced apart in the vertical direction, and the first air guide groove 14111 is located below the second air guide groove 14112.

[0098] Specifically, in the vertical direction, the first air guide slot 14111 is adjacent to the tip of the blade of the outdoor fan 40, and the second air guide slot 14112 is adjacent to the tail end of the blade of the outdoor fan 40. In this way, in the direction of the blade height, both the first air guide slot 14111 and the second air guide slot 14112 can guide the heat exchange airflow and eliminate eddies, resulting in good air guiding effect.

[0099] In some embodiments of this utility model, in the radial direction of the cross-flow fan, the distance between the circumferential inner wall of the first air guide groove 14111 and the cross-flow fan is less than the distance between the circumferential inner wall of the second air guide groove and the cross-flow fan. In this way, the first air guide groove 14111 can avoid some mounting structures on the plate 141 or other structural components in the outdoor unit 100 of the air conditioner.

[0100] In some other embodiments of this utility model, in the radial direction of the cross-flow fan, the distance between the circumferential inner wall of the first air guide groove 14111 and the cross-flow fan is equal to the distance between the circumferential inner wall of the second air guide groove and the cross-flow fan, which can improve the air guiding effect of the arc-shaped air guide groove 1411.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
