[0042] In existing air conditioner outdoor units, the electrical boxes are relatively large to accommodate multiple electrical components. However, for air conditioner outdoor units that require fewer electrical components, the existing electrical boxes occupy too much space within the outdoor unit casing, thus crowding out other electrical components. This not only increases the space occupied by the electrical boxes but also increases their cost.

[0043] like Figure 1 and Figure 2 As shown, some embodiments of this application provide an air conditioner outdoor unit, which may include a housing 1, forming the outer casing of the air conditioner outdoor unit. The interior of the housing 1 can be used to provide installation space. This air conditioner outdoor unit can be an outdoor air conditioning unit.

The air intake side of the fan 3 faces the inside of the fan compartment 13, and the air outlet side of the fan 3 faces the outside of the air outlet 15. When the fan 3 is running, the fan 3 can introduce air from outside the housing 1 into the compressor compartment 12 of the housing 1 through the air inlet 14, where it exchanges heat with the heat exchanger, and the heat-exchanged air is discharged into the space outside the housing 1 through the air outlet 15.

[0052] Please see Figure 2 As shown, in some embodiments, the outdoor unit of the air conditioner may include a motor bracket 4, which is disposed inside the housing 1. The motor bracket 4 may be disposed within the fan compartment 13, and the motor bracket 4 provides installation space for the fan 3. The fan 3 may be fixedly mounted on the motor bracket 4, and thus fixedly mounted within the fan compartment 13.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the heat exchanger may be located on the side wall of the fan compartment 13 near the housing 1, and abut against the inner side wall of the housing 1, and arranged opposite to the air inlet 14.

[0054] like Figure 2 As shown, in some embodiments, the housing 1 may include a top plate 16, and the top of the motor bracket 4 may be connected to the bottom surface of the top plate 16 of the housing 1.

[0055] like Figure 2 As shown, in some embodiments, the housing 1 may include a base plate 17, and the bottom end of the motor bracket 4 may be connected to the top surface of the base plate 17 of the housing 1.

[0056] Please see Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the outdoor unit of the air conditioner may include a first electrical box 5, which is disposed within the housing 1. In this embodiment, the first electrical box 5 may be disposed within the compressor compartment 12. The interior of the first electrical box 5 is hollow, and a first receiving cavity 50 may be provided inside the first electrical box 5. The first receiving cavity 50 may be used to house a circuit board.

[0057] In some embodiments, the outdoor unit of the air conditioner may further include a first control board 6.

The first accommodating cavity 50 can provide installation space for the first control board 6.

[0058] Please see Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the outdoor unit of the air conditioner may include a second electrical box 7, which may be disposed within the housing 1. In this embodiment, the second electrical box 7 may be disposed within the compressor compartment 12. The interior of the second electrical box 7 is hollow, and a second receiving cavity 70 may be provided inside the second electrical box 7. The second receiving cavity 70 may also be used to house a circuit board.

[0059] In some embodiments, the first electrical box 5 may be located at the top of the compressor chamber 12, and the second electrical box 7 may be located below the bottom of the first electrical box 5.

[0060] It should be noted that in some other embodiments, the second electrical box 7 may also be located in other positions of the first electrical box 5.

[0061] Please see Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the outdoor unit of the air conditioner may further include a second control board 8. The second control board 8 can be electrically connected to the compressor 2, the first control board 6, the fan 3, or external electrical components, so as to jointly control the operation of the compressor 2, the fan 3, or the external electrical components with the first control board 6.

[0062] Please see Figure 5 and Figure 6 As shown, in some embodiments, a first heat dissipation vent 51 may be provided on the bottom wall of the first electrical box 5. The first heat dissipation vent 51 can be used to connect the first accommodating cavity 50 and the outside of the first electrical box 5, so that air outside the first electrical box 5 can enter the first accommodating cavity 50 through the first heat dissipation vent 51, thereby achieving heat dissipation for the first control board 6 inside the first electrical box 5.

[0063] Please see Figure 3 and Figure 4 As shown, in some embodiments, the second electrical box 7 can cover part of the first heat dissipation vent 51 on the bottom surface of the first electrical box 5, that is, the other part of the first heat dissipation vent 51 can connect the first accommodating cavity 50 and the compressor chamber 12.

[0064] In some embodiments, a connecting line may be provided between the second controller and the first controller. The second control board 8 can be connected to the first control board 6 through the first heat dissipation vent 51. The first heat dissipation vent 51 enables the connection between the second control board 8 and the first control board 6. The first heat dissipation vent 51 enables electrical connection with the first control board 6 and the second control board 8, thereby allowing for quick installation of the second electrical box 7 without damaging the structure of the first electrical box 5, and simplifying the connection between the second electrical box 7 and the first electrical box 5. By placing the first control board 6 and the second control board 8 in different electrical boxes, the size of a single electrical box can be avoided from being too large, thereby reducing the manufacturing cost of a single electrical box.

[0065] Please see Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, one end of the first electrical box 5 extends into the fan compartment 13, and the end of the first electrical box 5 extending into the fan compartment 13 is supported on the partition 11. An air intake 52 is also provided on the side wall of the first electrical box 5 located in the fan compartment 13, and the air intake 52 connects the fan compartment 13 and the first receiving cavity 50. In this way, heat in the first receiving cavity 50 can flow through the air intake 52 into the fan compartment 13, and then flow with the airflow in the fan compartment 13 to the outside of the housing 1, improving the heat dissipation performance of the first electrical box 5.

[0066] In some embodiments, the air intake 52 is disposed on the side wall of the first electrical box 5 near the air outlet 15, and the air intake 52 is located around the air outlet 15. When the fan 3 is running, a negative pressure zone can be formed around the air outlet 15. By arranging the air intake 52 on the side wall of the first electrical box 5 near the air outlet 15 and being located around the air outlet 15, air can be effectively drawn from the first accommodating cavity 50 through the air intake 52, so that the heat in the first accommodating cavity 50 can automatically flow to the fan compartment 13 through the air intake 52, thereby improving the heat dissipation performance of the first electrical box 5.

[0067] Please see Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first electrical box 5 may include a body 53. A first receiving cavity 50 may be formed inside the body 53.

[0068] In some embodiments, the first electrical box 5 may include a cover plate 54. The cover plate 54 is disposed on the top surface of the body 53. The cover plate 54 is used to cover the top opening of the first receiving cavity 50. The cover plate 54 is disposed on the top of the body 53, which facilitates the installation of the first control plate 6 in the first receiving cavity 50 of the body 53.

[0069] Please see Figure 6 As shown, in some embodiments, a second heat dissipation vent 55 is provided on one side wall of the main body 53. The second heat dissipation vent can connect the first accommodating cavity 50 and the compressor chamber 12.

The second heat dissipation vent 55 can increase the airflow rate of the first accommodating cavity 50, thereby ensuring the heat dissipation efficiency of the first accommodating cavity 50.

[0070] In some embodiments, the second heat dissipation vent 55 may be located on the adjacent sidewall of the sidewall where the air intake vent 52 is located.

[0071] It should be noted that in some other embodiments, the second heat dissipation vent 55 may also be located on other side walls.

[0072] In some embodiments, a third heat dissipation vent 56 may be provided on another adjacent side wall of the main body 53. The third heat dissipation vent can connect the first accommodating cavity 50 and the compressor chamber 12. Air in the compressor chamber 12 can enter the first accommodating cavity 50 through the third heat dissipation vent 56, and then enter the fan chamber 13 through the air intake vent 52. The third heat dissipation vent 56 can further improve the airflow rate of the first accommodating cavity 50, thereby ensuring the heat dissipation efficiency of the first accommodating cavity 50.

[0073] In some embodiments, the third heat dissipation vent 56 may be located on the opposite sidewall of the sidewall where the air intake vent 52 is located.

[0074] It should be noted that in some other embodiments, the second heat dissipation vent 56 may also be located on other side walls.

[0075] Please see Figure 3 and Figure 4 In some embodiments, the first electrical box 5 may include a support plate 57.

The upper end of the support plate 57 is connected to the end of the first electrical box 5 away from the fan compartment 13. The lower end of the support plate 57 is connected to the inner wall of the housing 1. The support plate 57 may be located below the main body 53 and below the third heat dissipation vent. The support plate 57 may be arranged inclined downwards from the bottom of the main body 53 toward one side wall of the compressor compartment 12. The upper end of the support plate 57 may be connected to the lower edge of the third heat dissipation vent 56. The lower end of the support plate 57 may be fixed to the side wall of the compressor compartment 12.

[0076] In some embodiments, the top surface of the support plate 57 is an inclined surface, and a connection terminal 58 may be provided on this inclined surface. The inclined surface provides installation space for the connection terminal 58. The connection terminal 58 being located on the top surface of the support plate 57 facilitates connection with internal and external devices of the first electrical box 5. When air enters the first accommodating cavity 50 through the third heat dissipation port 56, it can improve the heat dissipation performance at the connection terminal 58.

[0077] Please see Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the top of the second electrical box 7 may be provided with an upwardly extending plug-in portion 71. One side edge of the first heat dissipation vent 51 can be inserted into the plug-in portion 71 to improve the connection stability between the second electrical box 7 and the first electrical box 5.

[0078] Please see Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments, the top of the second electrical box 7 may be provided with an upwardly extending snap-fit ​​portion 72. The snap-fit ​​portion 72 may be arranged at intervals with the plug-in portion 71. The other opposite side edge of the first heat dissipation vent 51 can be snapped with the snap-fit ​​portion 72, thereby using the plug-in portion 71 and the snap-fit ​​portion 72 to cooperate with the opposite two sides of the first heat dissipation vent 51, further improving the connection stability between the second electrical box 7 and the first electrical box 5.

[0079] In some embodiments, the second electrical box 7 can be detachably connected to the first electrical box 5 via a plug-in portion 71 and a snap-fit ​​portion 72. When the air conditioner only needs to be equipped with the first control board 6, the second electrical box 7 can be directly removed from the outdoor unit. When the air conditioner needs to be equipped with both the first control board 6 and the second control board 8, the second electrical box 7 can simply be installed on the first electrical box 5. Therefore, when the second control board 8 is not required, it can be removed from the first electrical box 5 without altering its structure. By detachably connecting the first electrical box 5 and the second electrical box 7, the detachable connection between the first control board 6 and the second control board 8 can be controlled, thereby enabling the outdoor unit to accommodate models with different control board requirements.

[0080] In some embodiments, a plug-in groove 711 is provided on the side wall of the plug-in portion 71. The plug-in groove 711 can be laterally opened in a direction away from the snap-fit ​​portion 72. One side edge of the first heat dissipation vent 51 can be inserted into the plug-in groove 711 through the lateral opening to improve the connection stability between the second electrical box 7 and the first electrical box 5.

[0081] In some embodiments, the engaging portion 72 may include a hook 721. The hook 721 may extend in a direction away from the insertion portion 71. The hook 721 may include an engaging wall and an inclined wall. The inclined wall is inclined downward in a direction away from the insertion portion 71. The engaging wall is used to engage with the other opposite side edge of the first heat dissipation port 51, so that when one side edge of the first heat dissipation port 51 is inserted into the insertion portion 71, the other opposite side edge of the first heat dissipation port 51 can abut against the inclined wall, and under the guidance of the inclined wall, the engaging wall can engage with the top surface of the other opposite side edge of the first heat dissipation port 51.

[0082] Please see Figure 7 and Figure 8 As shown. In some embodiments, a limiting opening 541 is provided on the bottom surface of the first electrical box 5. The limiting opening 541 can penetrate the bottom surface of the first electrical box 5 and can connect the first receiving cavity 50 and the fan compartment 13. A limiting member 73 is provided on the top surface of the second electrical box 7. The limiting member 73 can protrude from the top surface of the second electrical box 7. When one side edge of the first heat dissipation vent 51 is inserted into the insertion part 71 and the other side edge of the first heat dissipation vent 51 is engaged with the locking part 72, the limiting member 73 can extend into and be limited in the limiting opening 541, thereby limiting the second electrical box 7 in the first heat dissipation vent 51 and preventing the second electrical box 7 from shifting in the first heat dissipation vent 51.
