[0001] This utility model relates to the field of air conditioning technology, and in particular to an electrical control box, an outdoor air conditioning unit, and an air conditioner. Background Technology

[0002] The electrical control box of the outdoor unit of an air conditioner is mainly used to control the operation of air conditioning equipment such as the compressor, fan, and electric heating tape, thereby controlling the operation and temperature regulation of the air conditioner.

[0003] The existing sealing methods for the wiring holes of the outdoor unit electrical control box of air conditioners usually include the following: (1) rubber sealing, rubber parts are customized according to the shape of the electrical control box and the size of the wiring hole. The rubber parts are fixed by buckles and screws. The rubber parts are equipped with baffles perpendicular to the wiring direction. When wiring, the wires are inserted into the grooves in the rubber and the baffles block the external refrigerant; (2) glue sealing, O-shaped holes are opened on the wiring end face. When wiring, the wires pass through the O-shaped end face and are sealed with glue.

[0004] However, using rubber sealing strips at the wiring points requires mold making, is costly, and is difficult to install; using sealant for sealing makes maintenance difficult. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the prior art and provide an electrical control box whose structure can ensure the sealing of the wiring points of the electrical control box, reduce the number of parts required for sealing, reduce costs, and at the same time make wiring and maintenance inside the electrical control box more convenient.

[0006] This utility model is achieved through the following technical solution: an electrical control box, including a box body, a box cover, and an electrical control board. The box body has an opening, and the box cover closes to the opening of the box body and defines an installation cavity with the box body. The electrical control board is disposed in the installation cavity. The box body is provided with a receiving groove, and the receiving groove is provided with at least one through hole for wiring that connects the inside and outside of the box body. An elastic sealing element is provided in the receiving groove, and the elastic sealing element has a channel that connects the through hole for wiring and the inside of the box body.

[0007] Compared with existing technologies, the electrical control box provided by this utility model, through the design of the cover and opening, facilitates the installation of the electrical control board and the wiring operation with external devices. The inclusion groove inside the box facilitates the positioning and limiting of the elastic seal. The through-hole in the inclusion groove and the channel on the elastic seal allow for the routing of electrical cables connecting the electrical control box to external devices. The elastic seal ensures a seal between the inside and outside of the electrical control box. Therefore, this electrical control box ensures a tight seal at the wiring points, reduces the number of parts required for sealing, lowers costs, and makes wiring and maintenance within the box more convenient.

[0008] Furthermore, the opening includes a first opening and a second opening. The first opening is located on the upper surface of the box body, and the second opening is located on the side surface of the box body.

[0012] Furthermore, the channel is a slit, and the extension direction of the slit is the same as the axial direction of the through hole. The slit and the through hole are arranged in a one-to-one correspondence and are connected. The slit design helps to improve the sealing performance; the corresponding arrangement of the slit and the through hole simplifies the wiring path.

[0013] Furthermore, the elastic seal is made of open-cell polyethylene foam, and its shape matches the shape of the receiving groove. Using an elastic seal made of open-cell polyethylene foam reduces costs and facilitates installation.

[0014] Furthermore, a third opening for heat dissipation of the electronic control board is provided on one side of the housing. This third opening communicates with the mounting cavity, and the heat sink and some electronic components on the electronic control board are exposed outside the housing through the third opening. This third opening facilitates heat dissipation for the electronic control board, which helps to extend its lifespan.

[0015] Furthermore, the electrical control box also includes a bracket, a terminal block, and a terminal block cover. The bracket is connected to the box body, and the terminal block cover closes to the bracket, defining a second mounting cavity. The terminal block is disposed within the second mounting cavity and connected to the bracket. A fourth opening is provided on the other side of the box body, communicating with the mounting cavity within the box body and the second mounting cavity. The terminal block cover has a fifth opening on the side away from the fourth opening, communicating with the outside. The design of the fourth and fifth openings allows for external power supply to the electrical control box.

[0016] This utility model also provides an outdoor unit for an air conditioner, including the electrical control box as described above.

[0017] Furthermore, it also includes an outdoor unit housing, a fan, a compressor, and a wind deflector. The wind deflector is disposed inside the outdoor unit housing, and the electrical control box is disposed on top of the wind deflector. The wind deflector and the electrical control box divide the interior of the outdoor unit housing into a first installation space and a second installation space. The fan is disposed in the first installation space, and the compressor is disposed in the second installation space.

[0018] One side of the housing has a third opening for heat dissipation of the control board. This third opening communicates with the mounting cavity, and the heat sink and some electronic components on the control board are exposed outside the housing through this third opening. The control box also includes a bracket, a terminal block, and a terminal block cover. The bracket is connected to the housing, and the terminal block cover closes to the bracket, defining a second mounting cavity. The terminal block is disposed within the second mounting cavity and connected to the bracket. The other side of the housing has a fourth opening, which communicates with both the mounting cavity and the second mounting cavity within the housing. The terminal block cover has a fifth opening on the side away from the fourth opening, communicating with the outside. The third opening is located within the first mounting space, and both the second and fourth openings are located within the second mounting space. With this configuration, the heat sink and reactor on the control board can be exposed through the third opening into the second mounting space, allowing the fan to dissipate heat from the control board and improve heat dissipation efficiency. The second and fourth openings being located within the second mounting space facilitate wiring between the control box and equipment such as compressors and fans, as well as external connections.

[0019] Furthermore, the wind deflector is provided with a plurality of first ventilation holes, which connect the first installation space and the second installation space; the outdoor unit housing has a plurality of second ventilation holes on the side facing the compressor, which connect the second installation space and the outside of the outdoor unit housing.
