Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0045] At present, the top-outlet outdoor unit of the central air conditioner has many wires entering the electric control box, including compressor connection wires, fan connection wires, temperature sensor connection wires, etc. Generally, the connection wires of the electrical components enter the electric control box from the bottom surface and are connected to the electric control board. However, since the electrical components in the outdoor unit, such as the fan assembly, are installed above the electric control box, the connection wires used to connect the fan assembly to the electric control box need to pass through most of the components inside the outdoor unit, and then enter the electric control box through the bottom of the electric control box, which makes the installation process complicated or even impossible to install.

[0046] In order to solve the problem of complicated installation process of connecting wires between electrical components and electrical control boards, the present application proposes an electrical control box assembly, an outdoor unit having the electrical control box assembly, and an air conditioner having the outdoor unit, which can quickly and effectively connect electrical components and electrical control boards through connecting wires, and the operation process is simple and effective, reducing the complexity of the connecting wire installation process.

[0047] For the convenience of description, in the embodiments of the present application, only the air conditioner is taken as an example of a central air conditioner.

[0048] Central air conditioning consists of an indoor unit and an outdoor unit. The outdoor unit is usually installed outdoors, and the indoor unit is usually installed indoors. The outdoor unit and the indoor unit work together to achieve the air conditioner's cooling, heating, dehumidification and air purification functions to achieve comfortable air quality.

[0049] In a central air conditioner, there is usually one outdoor unit, and there can be multiple indoor units. Each indoor unit is provided with one or more air outlets to discharge the cooled, heated, dehumidified or purified air into the room through the air outlets. An indoor heat exchanger is usually provided in the indoor unit, and an outdoor heat exchanger is usually provided in the outdoor unit. The indoor heat exchanger and the outdoor heat exchanger are usually connected through a refrigerant pipeline, so that the refrigerant can flow between the indoor heat exchanger and the outdoor heat exchanger.

[0050] During the cooling process of the central air conditioner, the indoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, takes away the heat in the air in the indoor unit, and then makes the air discharged from the indoor unit the air after heat release and cooling, and the indoor unit blows cold air. At the same time, the outdoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air conditioner outdoor unit flowing through the condenser, so that the air in the outdoor unit brings the heat of the condenser to the outside of the outdoor unit, realizing the cooling process.

[0051] During the heating process of the central air conditioner, the outdoor heat exchanger is the evaporator, and the refrigerant in the evaporator absorbs heat from liquid to gas. In the process of refrigerant evaporation and heat absorption, the evaporator exchanges heat with the air flowing through the evaporator, and replaces the heat carried by the air in the air conditioner outdoor unit with the refrigerant in the evaporator. At the same time, the indoor heat exchanger is the condenser, and the refrigerant in the condenser changes from gas to liquid. In the process of refrigerant condensation and heat release, the condenser exchanges heat with the air in the air conditioner indoor unit flowing through the condenser, so that the air in the indoor unit takes away the heat carried by the condenser and discharges it from the indoor unit to the room outside the indoor unit, so that the indoor unit blows hot air, thereby realizing the heating process.

[0052] Combination Figure 1 and Figure 2As shown, in some embodiments of the present invention, the outdoor unit 1 includes a housing 10, and a mounting cavity for mounting various electrical components is formed inside the housing 10, wherein the various electrical components include an outdoor heat exchanger 20 and a compressor 30. Since the outdoor heat exchanger 20 and the compressor 30 release a large amount of heat during operation, and other electrical components also release a certain amount of heat during operation, in order to facilitate heat dissipation of the various electrical components in the housing 10, the outdoor unit 1 also includes a fan assembly 50, and the fan assembly 50 is connected to the mounting cavity, and the heat generated by the various electrical components in the housing 10 is discharged to the outside of the housing 10 through the action of the fan assembly 50. The fan assembly 50 can be arranged outside the housing 10 and placed above the housing 10, or the fan assembly 50 can be placed inside the housing 10 and arranged near the top. The fan assembly 50 is placed above the box 10 or on the top of the box 10, and an air outlet is formed on the top of the fan assembly 50, so that the fan assembly 50 can be convenient for discharging air toward the top of the box 10, and the air flow will not directly act on the operators around the box 10, thereby reducing the occurrence of accidental injuries to the operators. Among them, the box 10 is provided with a plurality of air holes 11, and when the fan assembly 50 is working, the air outside the box 10 can enter the inside of the box 10 through the air holes 11 and form an airflow, thereby cooling and dissipating the heat of the electrical components in the box 10.

[0053] In some embodiments of the present invention, the outdoor unit 1 further includes an electric control box assembly 40, which is connected to various electrical components and used to control various electrical components. The electric control box assembly 40 is arranged on the side wall of the housing 10 and is connected to the housing 10 in a detachable manner, so as to facilitate the disassembly and maintenance of the electric control box assembly 40. Specifically, the side wall of the housing 10 is provided with an open end 12, and the electric control box assembly 40 is arranged at the open end 12 and is used to shield the open end 12. By disassembling the electric control box assembly 40, the electrical components inside the housing 10 can be repaired or replaced. Among them, most of the electrical components in the housing 10 are respectively connected to the electric control box assembly 40, such as the fan assembly 50, the outdoor heat exchanger 20 and the compressor 30, and are controlled by the electric control box assembly 40.

[0054] Combination Figures 2 to 5 As shown, in some embodiments of the present invention, the electric control box assembly 40 includes a mounting plate 41 and an electric control board 42, the mounting plate 41 includes a main board portion 411 and a side panel portion 412 provided on at least one side of the main board portion 411, a first wire passing opening 4121 is provided at the top or near the top of the side panel portion 412, the main board portion 411 is provided with a second wire passing opening 4111, the electric control board 42 is provided on the main board portion 411, and the connecting wire 60 for connecting the electric control board 42 can pass through the first wire passing opening 4121 and the second wire passing opening 4111 in sequence and be connected to the electric control board 42.

[0055] Specifically, a side plate portion 412 is provided on the left and right sides of the main board portion 411, and the side plate portion 412 is used to be connected and fixed to the box body 10, so as to fix the electric control box assembly 40 to the box body 10. The two side plate portions 412 are respectively arranged at a first angle a with the main board portion 411, and the value range of the first angle a is 0°≤a≤180°.

[0056] Specifically, a can be any value between 0°…45°…90°…135°…180°, and the specific value can be determined according to the installation position of the electric control box assembly 40. For example, when the electric control box assembly 40 is entirely arranged on one of the panels of the box body 10, the main board portion 411 and the side board portion 412 are in the same plane, and the value of a is 0° or 180°. When the electric control box assembly 40 is arranged at the corner between two adjacent panels of the box body 10, at this time, the two side board portions 412 are respectively connected to different panels of different boxes 10, and the main board portion 411 is arranged between two different panels of the box body 10, and the first angle a can be greater than 0° and less than 180°, and can be specifically 135°, so as to facilitate the installation of the electric control box assembly 40.

[0057] In some embodiments of the present invention, the structures of the side panels 412 on both sides of the main panel 411 may be consistent or inconsistent. For the convenience of description, only the side panels 412 on both sides of the main panel 411 are described. Figure 3 The side plate portion 412 on the left side of the middle main plate portion 411 is taken as an example for description.

[0058] Since some electrical components of the outdoor unit 1 are arranged above the electric control box assembly 40, such as the fan assembly 50, when the fan assembly 50 is connected to the electric control board 42, if the connecting wire 60 is inserted into the electric control box assembly 40 through the bottom of the electric control box assembly 40, the connecting wire 60 will pass through most of the electrical components in the box body 10 in the vertical direction, and avoid during the insertion process, which will lead to the complexity of the assembly process, and easily cause damage to the connecting wire 60, and extend the length of the connecting wire 60. In the present application, by setting a first wire passing port 4121 on the top of the side plate part 412 and setting a second wire passing port 4111 on the main board part 411, one end of the connecting wire 60 can be connected to the fan 51 of the fan assembly 50, and the other end of the connecting wire 60 can be directly inserted into the electric control box assembly 40 through the first wire passing port 4121, the operation process is simple and effective, the complexity of the installation process of the connecting wire 60 is reduced, and the length of the connecting wire 60 is reduced, and the damage of the connecting wire 60 is reduced. Furthermore, since the first wire-passing opening 4121 is arranged on the side panel portion 412 and the electric control board 42 is arranged on the main panel portion 411, there is no overlapping area between the first wire-passing opening 4121 and the electric control board 42 in the vertical direction, which can prevent water from directly entering through the first wire-passing opening 4121 and falling onto the electric control board 42, thereby reducing damage to the electric control board 42 and improving the safety and reliability of the electric control box assembly 40.

[0059] like Figure 3 As shown, in some embodiments of the present invention, a second wire opening 4111 is provided at the connection between the main board portion 411 and the side board portion 412 , and the first wire opening 4121 and the second wire opening 4111 are provided on the same side of the main board portion 411 .

[0060] Specifically, a first wire-passing opening 4121 is provided on the side plate portion 412 on the left side of the main plate portion 411, and a second wire-passing opening 4111 is provided at the connection between the left edge of the main plate portion 411 and the side plate portion 412, so that the spacing between the first wire-passing opening 4121 and the second wire-passing opening 4111 in the vertical direction can be reduced, thereby reducing the length of the connecting line 60. The second wire-passing opening 4111 can be formed by partially recessing the main plate portion 411.

[0061] In some embodiments of the present invention, the second wire opening 4111 may also be provided at the bottom of the main board portion 411, and the connecting wire 60 may pass through the first wire opening 4121 and the second wire opening 4111 at the bottom of the main board portion 411 in sequence and be connected to the electric control board 42. However, compared with passing through the second wire opening 4111 on the side of the main board portion 411, this structure is relatively complicated.

[0062] Combination Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments of the present invention, at least a portion of the inner edge of the first wire-passing opening 4121 is provided with a flange 41211 or a chamfer.

[0063] Specifically, at least the bottom edge of the first wire passing opening 4121 is provided with a flange 41211. When the connecting wire 60 is inserted into the first wire passing opening 4121, the connecting wire 60 abuts against the bottom edge of the first wire passing opening 4121 due to its own gravity. Since the bottom edge of the first wire passing opening 4121 is provided with the flange 41211, the phenomenon of scratching the connecting wire 60 can be reduced, thereby improving the reliability of the use of the connecting wire 60.

[0064] Optionally, all inner edges of the first wire-passing opening 4121 are provided with flanges 41211 , thereby further reducing the occurrence of scratches caused by the connection wire 60 abutting against the edge, thereby improving the reliability of the use of the connection wire 60 .

[0065] Recombination Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments of the present invention, the opening size of the first wire-passing opening 4121 gradually decreases from bottom to top along the vertical direction.

[0066] Specifically, the first wire-passing opening 4121 is provided through the side plate portion 412, and the top of the first wire-passing opening 4121 is open, and the connecting wire 60 can be inserted into the first wire-passing opening 4121 through the top of the first wire-passing opening 4121. In the vertical direction, the top opening size of the first wire-passing opening 4121 is smaller than the bottom opening size, thereby forming a shrinkage structure at the top position of the first wire-passing opening 4121. After the connecting wire 60 passes through the first wire-passing opening 4121, due to the shrinkage structure at the top, the connecting wire 60 is not easy to automatically move out of the first wire-passing opening 4121 through the top of the first wire-passing opening 4121, thereby improving the positioning effect of the connecting wire 60.

[0067] Optionally, second guide surfaces 41212 are respectively provided on both sides above the first wire passing opening 4121, and the second guide surfaces 41212 are used to connect the top edge of the first wire passing opening 4121 and the top edge of the side panel 412. From bottom to top in the vertical direction, the size of the opening formed between the second guide surfaces 41212 on both sides gradually increases, that is, the top of the two second guide surfaces 41212 has the largest spacing size, so as to facilitate the connecting line 60 to pass through the top of the first wire passing opening 4121 and be inserted into the first wire passing opening 4121.

[0068] Combination Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments of the present invention, a first guide surface 41111 is provided at the bottom of the second wire opening 4111, and the first guide surface 41111 is inclined from bottom to top along the direction of the side plate portion 412 toward the main plate portion 411.

[0069] Specifically, the first guide surface 41111 is an inclined surface that rises obliquely from the outside to the inside of the main board portion 411, and can be a flat inclined surface or an arc-shaped inclined surface, so as to guide the connecting wire 60 to pass through the second wire-passing opening 4111 and connect with the electric control board 42. By providing the first guide surface 41111, the connecting wire 60 needs to pass through the first guide surface 41111 that is arranged upward before connecting with the electric control board 42, so as to prevent water from sliding onto the electric control board 42 through the connecting wire 60.

[0070] Specifically, the portion of the connecting line 60 disposed between the first wire-passing opening 4121 and the second wire-passing opening 4111 includes at least one bending portion 61, and the bending portion 61 includes a first line segment 611 and a second line segment 612 disposed at an angle in a vertical plane. The first line segment 611 extends from top to bottom along the vertical direction to below the second wire-passing opening 4111, and the second line segment 612 extends along the first guide surface 41111 and passes through the second wire-passing opening 4111, thereby forming a bending angle in the vertical plane at the connection between the first line segment 611 and the second line segment 612, and even if water moves along the connecting line 60, when the water flows to the connection between the first line segment 611 and the second line segment 612, it can fall naturally due to its own gravity, and will not continue to flow along the second line segment 612, thereby reducing the possibility of contact between the water and the electric control board 42.

[0071] Recombination Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments of the present invention, the second wire opening 4111 is at the same height as a portion of the electric control board 42 along the vertical direction.

[0072] Specifically, the second wire opening 4111 and the electric control board 42 have oppositely disposed parts in the horizontal direction perpendicular to the vertical direction, so that the connecting wire 60 passing through the second wire opening 4111 can be directly connected to a part of the structure of the electric control board 42, thereby reducing the setting length of the connecting wire 60.

[0073] Combination Figure 3 and Figure 6 As shown, in some embodiments of the present invention, the side plate portion 412 is further formed with a wire passing groove 4122 , and at least a portion of the wire passing groove 4122 is disposed between the first wire passing opening 4121 and the second wire passing opening 4111 .

[0074] Specifically, part of the structure of the side plate 412 is recessed to form a wire-passing groove 4122, which extends from the position of the first wire-passing opening 4121 to the bottom of the side plate 412 or a position close to the bottom, wherein part of the wire-passing groove 4122 is arranged between the first wire-passing opening 4121 and the second wire-passing opening 4111, so that the part of the connecting wire 60 that passes through the second wire-passing opening 4111 from the first wire-passing opening 4121 is in the wire-passing groove 4122, and the connecting wire 60 is limited by the wire-passing groove 4122, so that the arrangement of the connecting wire 60 is more orderly, which is convenient for subsequent maintenance and replacement. At the same time, since the bottom of the wire-passing groove 4122 extends to the bottom of the side plate 412 or a position close to the bottom, when water enters the wire-passing groove 4122, the water will eventually fall to the bottom of the wire-passing groove 4122 and eventually be discharged to the outside of the electric control box assembly 40.

[0075] Combination Figure 3 and Figure 6 As shown, in some embodiments of the present invention, a first mounting hole 4123 is further provided on the side panel portion 412, and the electric control box assembly 40 is fixedly installed on the box body 10 by connecting bolts that pass through the first mounting hole 4123 and a portion of the panel surface of the box body 10 in sequence.

[0076] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a water baffle 44 is further provided on the top of the main board portion 411 .
