[0002] Air conditioners typically consist of major components such as compressors and heat exchangers. The compressor drives the refrigerant circulation, while the heat exchanger acts as an evaporator or condenser to release and absorb heat, thereby regulating the ambient temperature.

[0003] Split-type air conditioners consist of an indoor unit and an outdoor unit. Air conditioners typically contain a compressor, heat exchanger, fan, and electrical control box. A partition usually divides the interior of the air conditioner into a compressor compartment and a fan compartment. The compressor and electrical control box are located in the compressor compartment, while the heat exchanger and fan are located in the fan compartment.

[0004] In related air conditioners, capacitors in the electrical box are typically installed horizontally. Installation requires additional clamps and screws, which can be problematic when there is insufficient space for capacitor installation and when capacitors of different lengths and specifications are incompatible.

[0045] like Figure 1 and Figure 2 As shown, some embodiments of this application provide an air conditioner that may include a housing 1, which forms the outer casing of the air conditioner. The interior of the housing 1 may be used to provide installation space. This air conditioner may be an outdoor unit. It should be noted that in other embodiments, the air conditioner may also be an indoor unit or an integrated air conditioner unit.

[0046] In some embodiments, the air conditioner may include a heat exchanger (not shown) which may be disposed within the housing 1. The heat exchanger is used to exchange heat with air outside the housing 1.

[0047] In some embodiments, the air conditioner may include a compressor (not shown) connected to a heat exchanger to form a refrigerant circulation loop. The refrigerant circulates within this loop, which consists of the compressor and the heat exchanger. During the refrigerant circulation, the heat exchanger may function as either a condenser or an evaporator, allowing the refrigerant to absorb heat through evaporation in the evaporator and release heat through condensation in the condenser, thereby enabling the air conditioner to perform either a cooling or heating cycle.

[0048] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a partition 11 may be provided inside the housing 1, dividing the space inside the housing 1 into a compressor compartment 110 and a fan compartment 120. The fan compartment 120 connects to the external space of the housing 1. The compressor may be located inside the compressor compartment 110. The heat exchanger may be located inside the fan compartment 120.

[0049] like Figure 1 As shown, in some embodiments, an air inlet 12 is provided on the outer wall of the housing 1, and the air inlet 12 may be located on the peripheral side wall of the housing 1. The air inlet 12 can connect to the outside of the housing 1 and connect the ventilation duct 120 and the external space of the housing 1. The heat exchanger can be arranged opposite to the air inlet 12. Air from outside the housing 1 enters the interior of the ventilation duct 120 through the air inlet 12 and exchanges heat with the heat exchanger.

[0050] It should be noted that in other embodiments, the air inlet 12 may also be located in other areas of the outer wall of the housing 1.

[0051] like Figure 1 As shown, in some embodiments, an air outlet 13 is provided on the outer wall of the housing 1, and the air outlet 13 may be located on the front wall of the housing 1. The air outlet 13 can connect to the outside of the housing 1, and connect the ventilation chamber 120 and the external space of the housing 1. The air in the ventilation chamber 120 that has exchanged heat with the heat exchanger can be blown to the outside of the housing 1 through the air outlet 13 and return to the external space of the housing 1.

[0052] It should be noted that in other embodiments, the air outlet 13 may also be located in other areas of the outer wall of the housing 1.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the air conditioner may include a fan 2. The fan 2 may be disposed within a fan compartment 120, and the fan 2 may be arranged opposite to the air outlet 13. The suction side of the fan 2 faces the interior of the fan compartment 120, and the discharge side of the fan 2 faces the exterior of the air outlet 13. When the fan 2 is running, the fan 2 can introduce air from outside the casing 1 into the compressor compartment 110 of the casing 1 through the air inlet 12, where it exchanges heat with the heat exchanger. The heat-exchanged air is then discharged into the space outside the casing 1 through the air outlet 13.

[0054] 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 120 near the housing 1, and abut against the inner side wall of the housing 1, and arranged opposite to the air inlet 12.

[0055] like Figure 2 and Figure 3As shown, in some embodiments, the air conditioner may include a motor bracket 3, which is disposed inside the housing 1. The motor bracket 3 may be disposed within the fan compartment 120, and the motor bracket 3 provides installation space for the fan 2. The fan 2 may be fixedly mounted on the motor bracket 3, and thus fixedly mounted within the fan compartment 120.

[0056] In some embodiments, the motor bracket 3 can extend along the height direction of the housing 1 so that the motor bracket 3 can be arranged vertically. The bottom end of the motor bracket 3 can be connected to the bottom surface inside the housing 1, and the top end of the motor bracket 3 can be connected to the top surface inside the housing 1 so as to stably support the fan 2 inside the fan compartment 120 of the housing 1.

[0057] like Figure 2 As shown, in some embodiments, the housing 1 may include a top plate 101, and the top of the motor bracket 3 may be connected to the bottom surface of the top plate 101 of the housing 1.

[0058] like Figure 2 As shown, in some embodiments, the housing 1 may include a base plate 102, and the bottom end of the motor bracket 3 may be connected to the top surface of the base plate 102 of the housing 1.

[0059] like Figure 2 and Figure 3 As shown, in some embodiments, the fan 2 may include a drive motor 21 and an impeller 22. The drive motor 21 is fixed on the motor bracket 3, and the impeller 22 is connected to the output shaft of the drive motor 21. The impeller 22 may be arranged opposite to the air outlet 13. The drive motor 21 can drive the impeller 22 to rotate inside the fan housing 120. The air generated by the rotation of the impeller 22 can draw air from outside the casing 1 into the fan housing 120 through the air inlet 12, exchange heat with the heat exchanger, and then be discharged into the space outside the casing 1 through the air outlet 13.

[0060] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the air conditioner may include an electrical box 4, which is disposed within the housing 1. For example, the electrical box 4 may be disposed within the compressor compartment 110. The electrical box 4 may be electrically connected to the compressor, fan 2, etc., to facilitate control of the operation of the compressor, fan 2, etc.

[0061] In some embodiments, the electrical box 4 may be disposed on the top of the press chamber 110 and fixed to the top of the partition 11. One end of the electrical box 4 may be fixed to the top of the partition 11, and the other end of the electrical box 4 may be fixed to the side wall of the press chamber 110.

[0062] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, a wire channel 401 may be provided on the outer wall of the electrical box 4. One end of the wire channel 401 may be connected to the fan compartment 120, and the other end of the wire channel 401 may be connected to the compressor compartment 110. The electrical connection wires in the fan compartment 120 may extend through the wire channel 401 and be arranged in the compressor compartment 110, thereby connecting the electrical connection wires of electrical components such as the fan 2 to the electrical components in the compressor compartment 110. The electrical connection wires in the fan compartment 120 may also extend through the wire channel 401 and be arranged in the electrical box 4.

[0063] In some embodiments, the cable tray 401 is arranged at an angle downwards in the direction from the compressor chamber 110 toward the fan chamber 120. Thus, when rainwater enters the cable tray 401, rainwater on the electrical connection wires within the cable tray 401 or rainwater within the cable tray 401 can flow downwards along the cable tray 401 toward the fan chamber 120, thereby preventing condensate from entering the compressor chamber 110.

[0064] like Figure 9 and Figure 10 As shown, in some embodiments, a drain outlet 402 may be provided on the bottom wall of the cable tray 401. The drain outlet 402 may connect to the space below the bottom of the electrical box 4. In this way, rainwater in the cable tray 401 can be drained into the space below the electrical box 4 through the drain outlet 402, preventing rainwater from flowing along the electrical connection wires in the cable tray 401 to the terminal block 451 and causing a short circuit.

[0065] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the electrical box 4 may include a base 41, with a mounting cavity 410 having a top opening formed within the base 41. The electrical box 4 may include a control board 43, which may be disposed within the mounting cavity 410. The electrical box 4 may include a capacitor 44, which may be disposed within the mounting cavity 410. The mounting cavity 410 can provide mounting space for devices such as the capacitor 44 and the control board 43. A wire channel 401 may be provided on the outer wall of the base 41.

[0066] In some embodiments, the electrical box 4 may include a top cover 42, which is disposed on the top surface of the base 41 and is used to cover the top opening of the mounting cavity 410. The top cover 42 is disposed on the top of the base 41, which facilitates the installation of electrical components in the mounting cavity 410 of the base 41.

[0067] In some embodiments, a through hole 411 may be provided on the inner bottom surface of the mounting cavity 410. A surrounding wall 412 is provided within the mounting cavity 410, surrounding the through hole 411, and a capacitor groove 413 may be formed on the inner side of the surrounding wall 412. The capacitor groove 413 extends along the height direction of the mounting cavity 410, with its top end open and communicating with the inside of the mounting cavity 410, and its bottom end communicating with the outside of the base 41 through the through hole 411. A capacitor 44 can be installed through the capacitor groove 413, with its bottom end passing through the through hole 411 and extending downwards into the space below the bottom of the base 41. By using the structural design of the capacitor slot 413 and the surrounding wall 412 within the mounting cavity 410, the capacitor 44 can be installed downwards into the mounting slot through the top opening of the capacitor slot 413. The bottom end of the capacitor 44 can extend downwards through the through hole 411 and be arranged in the space below the bottom of the base 41. This utilizes the space below the bottom of the electrical box 4 to provide additional installation space for the capacitor 44, solving the problem of insufficient installation space for the capacitor 44 within the electrical box 4. At the same time, capacitors 44 of different lengths can be fixed in the capacitor slot 413 of the electrical box 4, so that the lengths of the capacitors 44 extending downwards through the through hole 411 vary, thus enabling compatibility with various capacitors 44 of different lengths.

[0068] like Figure 10 , Figure 11 and Figure 12 As shown, in some embodiments, the top surface of the enclosure 412 forms a limiting surface 4121, which supports the peripheral sidewall of the top of the capacitor 44 on the limiting surface 4121, thereby supporting the capacitor 44 and fixing it in the capacitor slot 413. In this way, the limiting surface 4121 can lock and limit the capacitor 44, preventing it from falling down from the capacitor slot 413 to the bottom of the electrical box 4.

[0069] like Figure 10 As shown, in some embodiments, the inner sidewall of the enclosure 412 is provided with fixing ribs 4122 extending along the height direction of the capacitor groove 413. Multiple fixing ribs 4122 can be provided, and these ribs are arranged sequentially at intervals along the circumference of the capacitor groove 413. The peripheral sidewall of the capacitor 44 can abut against the multiple fixing ribs 4122 respectively, so as to clamp and fix the capacitor 44 within the capacitor groove 413 by the multiple fixing ribs 4122. The fixing ribs 4122 can reduce the contact area between the outer wall of the capacitor 44 and the groove wall of the capacitor groove 413, while the cooperation of the multiple fixing ribs 4122 can stably clamp and fix the capacitor 44 within the capacitor groove 413.

[0070] like Figure 10 , Figure 11 and Figure 12As shown, the periphery of the capacitor slot 413 is provided with an upwardly extending elastic buckle 414, which can extend upward from part of the surrounding wall 412. The upper end of the elastic buckle 414 can be snapped onto the top wall of the capacitor 44. By cooperating with the limiting surface 4121 at the top of the surrounding wall 412, the capacitor 44 can be limited in the height direction, thereby fixing the capacitor 44 in the capacitor slot 413.

[0071] In some embodiments, a limiting rib 441 is provided on the peripheral sidewall of the top of the capacitor 44. The limiting rib 441 can be arranged circumferentially around the peripheral sidewall of the capacitor 44. The bottom of the limiting rib 441 can be supported on the limiting surface 4121, and the upper end of the elastic buckle 414 can be snapped onto the top surface of the limiting rib 441. By cooperating with the limiting rib 441, the elastic buckle 414, and the limiting surface 4121, the degree of freedom of the capacitor 44 in the height direction can be restricted, thereby fixing the capacitor 44 in the capacitor slot 413.

[0072] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the end of the base 41 near the fan compartment 120 can be fixed to the partition 11, allowing this end of the base 41 to be exposed outside the fan compartment 120. A heat dissipation window 415 is provided on the side wall of the end of the base 41 near the fan compartment 120, connecting the fan compartment 120 and the mounting cavity 410. Thus, heat within the mounting cavity 410 can flow through the heat dissipation window 415 into the fan compartment 120, and then with the airflow within the fan compartment 120, flow to the outside of the housing 1, improving the heat dissipation performance of the electrical box 4.

[0073] like Figure 10 and Figure 14 As shown, the heat dissipation window 415 may include a plurality of heat dissipation holes 4151, which are spaced apart on the side wall of the base 41 near the end of the fan compartment 120. The plurality of heat dissipation holes 4151 can ensure the airflow rate at the heat dissipation window 415 and ensure the heat dissipation performance of the plurality of heat dissipation windows 415.

[0074] like Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the heat dissipation window 415 is disposed on the side wall of the base 41 near the air outlet 13, and the heat dissipation window 415 is located around the air outlet 13. When the fan 2 is running, a negative pressure zone can be formed around the air outlet 13. By arranging the heat dissipation window 415 on the side wall of the base 41 near the air outlet 13 and being located around the air outlet 13, the air in the mounting cavity 410 can be effectively drawn out through the heat dissipation window 415, so that the heat in the mounting cavity 410 can automatically flow to the fan compartment 120 through the heat dissipation window 415, thereby improving the heat dissipation performance of the electrical box 4.

[0075] In some embodiments, a partition rib 416 may be provided within the base 41, and the partition rib 416 may be plate-shaped. The partition rib 416 can divide the mounting cavity 410 into a first space 4101 and a second space 4102. The first space 4101 and the second space 4102 are located on opposite sides of the partition rib 416. The capacitor slot 413 and the surrounding wall 412 may be located within the first space 4101, allowing the capacitor 44 to be located within the first space 4101. The control board 43 may be located within the second space 4102. Dividing the mounting cavity 410 into the first space 4101 and the second space 4102 by the partition rib 416 facilitates the separate installation of various components, thereby improving the installation efficiency of the components inside the electrical box 4. The dimensions of the second space 4102 may be consistent with the dimensions and outline of the control board 43, allowing the control board 43 to be fitted and installed within the second space 4102. The partition 11 can effectively prevent dust and insects from entering the second space 4102, avoiding contact with the top of the main control board and preventing short circuits.

[0076] In some embodiments, the first space 4101 may be located on the side of the second space 4102 near the fan compartment 120, and correspondingly, the second space 4102 may be located on the side of the first space 4101 near the compressor compartment 110. A heat dissipation window 415 may be located on the side wall of the base 41 corresponding to the first space 4101, and the heat dissipation window 415 may connect the fan compartment 120 and the first space 4101. A ventilation hole 4161 may be provided on the partition rib 416, and the ventilation hole 4161 may connect the first space 4101 and the second space 4102. Thus, heat and air in the second space 4102 can enter the first space 4101 through the ventilation hole 4161, then flow into the fan compartment 120 through the heat dissipation window 415, and be discharged outside the casing 1 through the air outlet 13, ensuring the heat dissipation performance of the control board 43. Multiple ventilation holes 4161 can be provided. Multiple ventilation holes 4161 can ensure the air flow rate of the second space 4102, thereby ensuring the heat dissipation efficiency of the second space 4102.

[0077] In some embodiments, the base 41 has an open area on the side wall of the compressor chamber 110, which connects the second space 4102 and the compressor chamber 110. Air in the compressor chamber 110 can enter the second space 4102 through the open area, and then enter the first space 4101 through the ventilation hole 4161. The open area can increase the airflow rate of the second space 4102, thereby ensuring the heat dissipation efficiency of the second space 4102.

[0078] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the open area of ​​the base 41 may include a first open area 4103a, which may be located on the side wall of the second space 4102 away from the first space 4101, and on the side wall of the base 41 away from the fan hopper 120. The first open area 4103a may connect the second space 4102 and the compressor hopper 110.

[0079] In some embodiments, the open area of ​​the base 41 may include a second open area 4103b, which may be disposed on the front sidewall of the second space 4102 and the front sidewall of the base 41. The second open area 4103b may connect the second space 4102 and the compressor chamber 110.

[0080] In some embodiments, the electrical box 4 may include a support plate 45, which may be disposed below the base 41 and below the first open area 4103a. The support plate 45 may be arranged inclined downwards from the bottom of the base 41 toward one side wall of the press chamber 110. The upper end of the support plate 45 may be connected to the lower edge of the first open area 4103a. The lower end of the support plate 45 may be fixed to the side wall of the press chamber 110. The top surface of the support plate 45 is an inclined surface, which can provide installation space for the terminal block 451. The terminal block 451 disposed on the top surface of the support plate 45 facilitates connection with internal and external devices of the electrical box 4. When air enters the second space 4102 through the first open area 4103a, the heat dissipation performance at the terminal block 451 can be improved.

[0081] like Figure 9 , Figure 13 and Figure 14 As shown, in some embodiments, the first space 4101 may be provided with spaced-apart slots 4104 and positioning posts 4105. The electrical box 4 may include an AC contactor 46, one end of which can be snapped into the slot 4104, and the other end of which is provided with a positioning hole 461. The positioning post 4105 can be inserted into the positioning hole 461, thereby positioning and installing the AC contactor 46 in the first space 4101 and restricting the AC contactor 46. In addition, AC contactors 46 of different heights and sizes can be fixed in the first space 4101.

[0082] In some embodiments, a fixing hole 4106 may be provided in the first space 4101, and the fixing hole 4106 may be arranged at intervals with the positioning post 4105. The AC contactor 46 can be installed in the first space 4101 through the fixing hole 4106, so that the AC contactor 46 can be effectively fixed with a single screw.

[0083] like Figure 9 and Figure 10As shown, in some embodiments, the electrical box 4 may include a magnetic ring 47, which may be disposed within the second space 4102. The second space 4102 may be provided with snap fasteners 417, and at least two snap fasteners 417 may be provided, located on opposite sides of the magnetic ring 47. The magnetic ring 47 is secured within the second space 4102 by at least two snap fasteners 417, which can improve the installation efficiency and stability of the magnetic ring 47.

[0084] In some embodiments, one end of the magnetic ring 47 may be provided with a wire-blocking rib 418. Two wire-blocking ribs 418 may be provided, and a wire-passing hole may be formed between the two wire-blocking ribs 418 so that the connecting wire at one end of the magnetic ring 47 can be passed through and installed in the wire-passing hole.
