However, applications of other processes and/or use of other materials are conceivable for those of ordinary skill in the art.

[0025] An air conditioner outdoor unit 1000 according to an embodiment in a second aspect of the present disclosure is briefly described with reference to FIG. 1. The air conditioner outdoor unit 1000 includes an electric control box assembly 100 according to an embodiment in a first aspect of the present disclosure.

[0026] As illustrated in FIG. 1, the air conditioner outdoor unit 1000 according to the second aspect of the present disclosure includes a housing 200, a fan impeller 300, and the electric control box assembly 100 according to the first aspect of the present disclosure. The fan impeller 300 and the electric control box assembly 100 are disposed in the housing 200.

[0027] The electric control box assembly 100 according to the embodiment in the first aspect of the present disclosure is described below with reference to FIG. 2 to FIG. 6.

[0028] As illustrated in FIG. 2 to FIG. 5, the electric control box assembly 100 according to the embodiment in the first aspect of the present disclosure is used for an air conditioner outdoor unit 1000. The electric control box assembly 100 includes an electric control box 10, an electric control element 20 and a heating element 30. The electric control box 10 defines a first cavity 14 and a heat dissipation air duct 13. The first cavity 14 is not in communication with the heat dissipation air duct 13. The heat dissipation air duct 13 has a heat dissipation inlet 131 and a heat dissipation outlet 132. The electric control element 20 is disposed in the first cavity 14. The heating element 30 is disposed in the heat dissipation air duct 13.

[0029] In an exemplary embodiment of the present disclosure, an accommodation cavity may be formed in the electric control box 10. The accommodation cavity may be configured to accommodate the electric control element 20 and the heating element 30. The electric control box 10 can provide a mounting space and protection for the electric control element 20 and the heating element 30. Also, the electric control element 20 and the heating element 30 can be integrated into the electric control box 10, increasing aesthetics and integration of the electric control box assembly 100.

[0030] The first cavity 14 is formed as a sealed space. The electric control element 20 is disposed in the first cavity 14, which can effectively prevent impurities such as dust and rainwater from entering the first cavity 14 and thus damaging the electric control element 20. Also, when the air conditioner outdoor unit 1000 experiences abnormal conditions such as refrigerant leakage, a refrigerant can also be effectively prevented from entering the first cavity 14 and causing a sparking incident of the electric control element 20, effectively preventing the air conditioner outdoor unit 1000 from catching a fire caused by the refrigerant leakage. Therefore, overall safety of the air conditioner outdoor unit 1000 can be improved.

[0031] The heat dissipation air duct 13 can guide an airflow and define a flow direction of the airflow. The heat dissipation air duct 13 has the heat dissipation inlet 131 and the heat dissipation outlet 132. The heating element 30 is disposed in the heat dissipation air duct 13. When the air conditioner outdoor unit 1000 is in operation, the airflow may enter the heat dissipation duct through the heat dissipation inlet 131, and then perform heat exchange with the heating element 30 in the heat dissipation air duct 13 to cool the heating element 30. The heat-exchanged airflow is discharged through the heat dissipation outlet 132, in such a manner that the heating element 30 may not malfunction due to overheating during normal use. Therefore, operational safety of the heating element 30 and safety and reliability of the electric control box assembly 100 can be improved.

[0032] With the electric control box assembly 100 according to the embodiments of the present disclosure, by defining, in the electric control box 10, the first cavity 14 and the heat dissipation air duct 13 which are not in communication with each other, operational safety of the electric control element 20 can be ensured, effectively preventing occurrence of the sparking incident of the electric control element 20 caused by refrigerant leakage. Also, a heat dissipation effect on the heating element 30 can also be ensured, preventing the heating element 30 from malfunctioning due to overheating during normal operation. Therefore, operational safety of the electric control box assembly 100 can be improved, further enhancing safety and reliability of the air conditioner outdoor unit 1000.

[0033] According to some embodiments of the present disclosure, as illustrated in FIG. 2 and FIG. 4, the electric control box 10 includes a box body 11 and a box cover 12. The box body 11 has an open side. The box cover 12 covers the open side of the box body 11. The heating element 30 and the electric control element 20 are disposed at a side of the box cover 12 facing the box body 11. The heat dissipation inlet 131 and the heat dissipation outlet 132 are formed at the box body 11. The box body 11 has the accommodation cavity. The accommodation cavity may accommodate the heating element 30 and the electric control element 20 in the electric control box. The box cover 12 covers the open side of the box body 11 to prevent dust and other impurities from entering, improving safety of the electric control box assembly 100.

[0034] For example, as illustrated in FIG. 1, when the electric control box assembly 100 is disposed at the air conditioner outdoor unit 1000, the box cover 12 is disposed above the box body 11. That is, the heating element 30 and the electric control element 20 are placed upside down. In this way, the heating element 30 and the electric control element 20 can be protected, effectively avoiding damage to the heating element 30 and the electric control element 20 caused by accumulation of water, dust, or other impurities, and further improving the operational safety of the electric control box assembly 100.

[0035] According to some embodiments of the present disclosure, as illustrated in FIG. 5, the electric control box assembly 100 further includes a hood plate 40 connected to the box cover 12 and disposed at an outer side of the heating element 30. The hood plate 40 and the box body 11 define the heat dissipation air duct 13. The hood plate 40 cooperates with the box body 11 to isolate the first cavity 14 from the heat dissipation air duct 13, ensuring sealing of the first cavity 14 and thus effectively preventing the refrigerant or other impurities from entering the first cavity 14 through the heat dissipation air duct 13 and causing damage to the electric control element 20. Therefore, safety of the electric control element 20 and safety and reliability of an entire unit can be enhanced. Also, the hood plate 40 may also be configured to isolate the heating element 30 from the electric control element 20, effectively avoiding damage to the electric control element 20 caused by overheating of the heating element 30. Therefore, the operational safety of the electric control box assembly 100 can be improved.

[0036] According to some embodiments of the present disclosure, as illustrated in FIG. 5, the hood plate 40 includes an annular portion and a baffle portion. The annular portion is connected to the box cover 12 and extends annularly in a circumferential direction of the heating element 30. The baffle portion is connected to a side of the annular portion facing away from the box cover 12 and extends in a circumferential direction of the annular portion. The box body 11 is provided with a surrounding plate 111 extending in the circumferential direction of the annular portion. A peripheral edge of the surrounding plate 111 is sealingly connected to a peripheral edge of the hood plate 40 to define the heat dissipation air duct 13.

[0037] The peripheral edge of the surrounding plate 111 is sealingly connected to the peripheral edge of the hood plate 40, which can not only define the heat dissipation air duct 13 but also completely isolate the heat dissipation air duct 13 from the first cavity 14. Also, the sealed connection between the peripheral edge of the surrounding plate 111 and the peripheral edge of the hood plate 40 can further define an airflow direction of the heat dissipation air duct 13, ensuring that the airflow flows in the circumferential direction of the heating element 30 and preventing the airflow from escaping in directions other than the heat dissipation outlet 132. In this way, a reduction in airflow passing through the heating element 30 can also be avoided, preventing a decrease in a cooling effect. Further, the cooling effect of the heating element 30 can be ensured and thus the heating element 30 can be prevented from malfunctioning due to overheating during normal use, enhancing the safety and reliability of the electric control box assembly 100.

[0038] According to some embodiments of the present disclosure, as illustrated in FIG. 6, the surrounding plate 111 includes a side plate portion 1111 and a top plate portion 1112. The side plate portion 1111 extends in the circumferential direction of the annular portion and abuts with the baffle portion in the circumferential direction of the annular portion. The top plate portion 1112 is connected to an end of the side plate portion 1111 away from the box cover 12 and sealingly connected to the baffle portion.

[0039] The surrounding plate 111 is connected to the hood plate 40, to enable the heat dissipation air duct 13 to have only two ventilation openings, i.e., the heat dissipation inlet 131 and the heat dissipation outlet 132. In this way, the airflow can move only from the heat dissipation inlet 131 to the heat dissipation outlet 132, providing targeted heat dissipation for the heating element 30. Further, the cooling effect of the heating element 30 can be enhanced, and thus the heating element 30 can be prevented from malfunctioning due to overheating during normal use, enhancing the safety and reliability of the electric control box assembly 100.

[0040] For example, as illustrated in FIG. 4, a first plate portion and a second plate portion are formed at the top plate portion 1112. The first plate portion extends horizontally. An end of the second plate portion is connected to an end of the first plate portion, and another end of the second plate portion extends towards the heating element 30 to form an angle with the first plate portion. In this way, the top plate portion 1112 can be arranged in the circumferential direction of the heating element 30, defining a movement range of the airflow and increasing a cooling area of the airflow on the heating element 30. Further, a cooling effect of the airflow on the heating element 30 can be improved.

[0041] According to some embodiments of the present disclosure, as illustrated in FIG. 5, the electric control box assembly 100 further includes an electric control board 50 disposed at the side of the box cover 12 facing the box body 11. The electric control element 20 and the heating element 30 are disposed at the electric control board 50. The electric control board 50 is an important component of the electric control box assembly 100. The electric control board 50 is composed of many unit circuits. Various input signals are processed by the electric control board 50 to control the entire air conditioner outdoor unit through an output circuit. The electric control board 50 serves as a control center of an electric control system. Also, an electrical component for controlling the air conditioner outdoor unit 1000 is mounted at the electric control board 50, to control operation of a compressor, a fan, an electric heating tape, and other air conditioning devices.

[0042] According to some embodiments of the present disclosure, as illustrated in FIG. 5, the electric control box assembly 100 further includes a heat dissipation member 60 disposed at an outer side of the first cavity 14 and an outer side of the heat dissipation air duct 13. The heat dissipation member 60 is connected to the electric control board 50 and configured to dissipate heat from the electric control board 50. The heat dissipation member 60 may perform heat conduction, which can transfer heat generated from the electric control board 50 to the heat dissipation member 60, and then the heat is dissipated from the heat dissipation member 60 into the air, completing heat dissipation of the electric control board 50 and thus improving operational safety of the electric control board 50. The heat dissipation member 60 may have various types. For example, the heat dissipation member 60 may be a heat sink.

[0043] According to some embodiments of the present disclosure, as illustrated in FIG. 6, the heat dissipation inlet 131 faces the heat dissipation member 60 and is in communication with the heat dissipation member 60. The heat dissipation outlet 132 faces away from the heat dissipation member 60. In an exemplary embodiment of the present disclosure, the heat dissipation inlet 131 and the heat dissipation member 60 are located at a side of the electric control box 10 facing a fan impeller 200. In this way, an airflow driven by the fan impeller 200 can not only perform heat exchange with the heating element 30, but also perform heat exchange with the heat dissipation member 60, achieving overall cooling of the electric control box assembly 100 and further improving the operational safety of the electric control box assembly 100.

[0044] For example, as illustrated in FIG. 6, the heat dissipation inlet 131 and the heat dissipation outlet 132 are arranged opposite to each other, which can facilitate circulation of the airflow and increase smoothness of airflow passage, improving the heat dissipation effect on the heating element 30. Therefore, safety and reliability of the heating element 30 during use can be enhanced.

[0045] According to some embodiments of the present disclosure, as illustrated in FIG. 5, the heating element 30 includes a base 31 and a heating body 32 disposed at the base 31. The base 31 is fixedly connected to the electric control board 50. The base 31 may be configured to mount the heating body 32, and also isolate the electric control board 50 from the heating body 32, effectively avoiding damage to the electric control board 50 caused by overheating of the heating body 32. Therefore, the operational safety of the electric control box assembly 100 can be improved.

[0046] In some embodiments, the base 31 is fixedly connected to the hood plate 40 by a snap-fit engagement. A plurality of protrusions are formed at the base 31. The hood plate 40 has grooves formed at a side of the hood plate 40 facing the box cover 12. The grooves are engaged with the protrusions. The grooves correspond to the protrusions in a one-to-one correspondence. In this way, convenience of mounting and disassembly of the base 31 and the hood plate 40 can be improved, enhancing convenience of mounting, disassembly, and maintenance of the electric control box assembly 100.

[0047] According to some embodiments of the present disclosure, the box body 11 is connected to the box cover 12 by a snap-fit engagement and/or via a fastener. That is, the box body 11 and the box cover 12 may be connected to each other only by the snap-fit engagement, which can improve convenience of connection and disassembly between the box body 11 and the box cover 12. Alternatively, the box body 11 and the box cover 12 may be connected to each other only via the fastener, which can increase tightness of the connection between the box body 11 and the box cover 12, improving sealing of the electric control box assembly 100. In addition, the box body 11 and the box cover 12 may also be connected to each other both by the snap-fit engagement and via the fastener, which can improve the sealing of the electric control box assembly 100 while increasing the convenience of mounting and disassembly of the electric control box assembly 100.

[0048] The snap-fit engagement may include various types, for example, a buckle engagement. The fastener also includes various types. For example, the fastener may be a bolt or a screw.

[0049] For example, as illustrated in FIG. 4, an engagement groove is further formed at the box cover 12. The box body 11 has an extension portion formed at a peripheral edge of the box body 11. The extension portion extends towards the box cover 12. The extension portion is engaged with the engagement groove. When the electric control box assembly 100 is used for the air conditioner outdoor unit 1000, the box cover 12 is disposed above the box body 11. In this way, the box cover 12 is connected to the box body 11 via the engagement groove, which can effectively prevent impurities such as rainwater from entering the box body 11 along a connection between the box cover 12 and the box body 11 and causing damage to the electric control element 20. Therefore, the operational safety of the electric control box assembly 100 can be improved.

[0050] According to some embodiments of the present disclosure, the heating element 30 is a Power Factor Correction (PFC) inductor. The PFC inductor can improve a power factor in a circuit, reducing a reactive power in the circuit, and thus enhancing an effect of power conversion.

[0051] Further, the PFC inductor is an enameled wire, such that exposure thereof may not cause sparking, further improving the safety of the electric control box assembly 100 and enhancing safety and reliability of the entire unit.

[0052] The air conditioner outdoor unit 1000 according to the embodiment in the second aspect of the present disclosure includes a housing 200; a fan impeller 300; and the electric control box assembly 100 according to the embodiment of the first aspect of the present disclosure. The fan impeller 300 and the electric control box assembly 100 are disposed in the housing 200.

[0053] The housing 200 provides a mounting space for the fan impeller 300 and the electric control box 10. The fan impeller 300 is adapted to drive the airflow in the heat dissipation air duct 13 to flow from the heat dissipation inlet 131 to the heat dissipation outlet 132, realizing cooling of the heating element 30 of the electric control box assembly 100.

[0054] For example, as illustrated in FIG. 1, the electric control box assembly 100 is disposed obliquely above the fan impeller 300 assembly. The heat dissipation inlet 131 faces the fan impeller 300. The heat dissipation outlet 132 faces away from the fan impeller 300. In this case, when the fan impeller 300 rotates, a peripheral airflow may be driven to rotate in a circumferential direction of the fan impeller 300, driving the airflow to enter via the heat dissipation inlet 131. Also, since the heat dissipation outlet 132 faces away from the fan impeller 300, no airflow is generated at the heat dissipation outlet 132, resulting in no resistance at the heat dissipation outlet 132, which can facilitate smooth discharge of the airflow. Therefore, the heat dissipation effect on the heating element 30 can be improved.

[0055] In the air conditioner outdoor unit 1000 according to the embodiments of the present disclosure, by disposing the electric control box assembly 100 according to the embodiment of the first aspect above, overall performance of the air conditioner outdoor unit 1000 can be improved.
