Any embodiment described in this application as exemplary is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is provided to enable any person skilled in the art to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be consistent with the widest scope consistent with the principles disclosed herein.

[0034] To facilitate understanding of the solution of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.

[0035] See also Figure 1 and Figure 2 In the first aspect, an embodiment of the present application provides a waterproof cover 11, which has a first cover shell 111 provided with a first fixing portion 1111, a second cover shell 112 provided with a second fixing portion 1121, and a flexible connection portion 113 connecting the first cover shell 111 and the second cover shell 112, so that the second cover shell 112 can be rotatably overlapped on the first cover shell 111 around the flexible connection portion 113; when the second cover shell 112 is overlapped on the first cover shell 111, the first fixing portion 1111 and the second fixing portion 1121 are fixedly connected.

[0036] The waterproof cover 11 provided in the embodiment of the present application has a first cover shell 111 and a second cover shell 112 that can be rotatably overlapped through a flexible connection portion 113; in this way, a single sheet metal part having the first cover shell 111, the second cover shell 112 and the flexible connection portion 113 can be formed through a sheet metal process, and then the first cover shell 111 and the second cover shell 112 can be overlapped and fixed by bending along the flexible connection portion 113 to form the waterproof cover 11. The structure and molding process are simple, the cost is low, the number of parts is reduced, and the waterproof cover 11 has high stability.

[0037] In some embodiments, the first housing 111, the flexible connector 113, and the second housing 112 are integrally formed. The waterproof cover 11 provided herein can be manufactured from a single sheet metal using conventional methods such as numerical control. This method is simple and convenient, reduces the number of parts compared to assembling multiple sheet metals, and provides a more efficient and stable integrated design.

[0038] In some embodiments, the flexible connection portion 113 includes multiple spaced-apart sub-connections, each of which connects the first housing 111 and the second housing 112. The flexible connection portion 113 can be formed by punching multiple sections of material from the connection between the first housing 111 and the second housing 112, thereby leaving multiple sub-connections formed from a small amount of material. The flexible connection portion 113 can be smoothly bent and rotated by human operation to securely connect the first fixing portion 1111 and the second fixing portion 1121.

[0039] In yet other embodiments, the thickness of the flexible connection portion 113 is thinner than the thickness of the area on the first housing 111 where the flexible connection portion 113 is connected, and the thickness of the flexible connection portion 113 is thinner than the thickness of the area on the second housing 112 where the flexible connection portion 113 is connected. Thus, the flexible connection portion 113 is more flexible than the first housing 111 and the second housing 112, allowing the second housing 112 to rotate stably relative to the first housing 111.

[0040] In some embodiments, when the first fixing portion 1111 and the second fixing portion 1121 are fixedly connected, the first housing 111 and the second housing 112 jointly define a first air inlet 114. Specifically, the first fixing portion 1111 is disposed on a side of the first housing 111 away from the flexible connection portion 113, and the second fixing portion 1121 is disposed on a side of the second housing 112 away from the flexible connection portion 113. In other words, the first air inlet 114 is located on a side away from the flexible connection portion 113.

[0041] It can be understood that the first fixing portion 1111 and the second fixing portion 1121 can be connected by conventional methods known in the art. For example, the first fixing portion 1111 and the second fixing portion 1121 can be assembly holes, and the connection between the first fixing portion 1111 and the second fixing portion 1121 is achieved by fixing them to the assembly holes with screws or rivets. For another example, the first fixing portion 1111 and the second fixing portion 1121 can also be snap buckles, and the connection between the first fixing portion 1111 and the second fixing portion 1121 is achieved by snap-fitting, etc.

[0042] In some embodiments, a first air outlet 115 is provided on the second housing 112 , and the first air inlet 114 is connected to the first air outlet 115 .

[0043] In some embodiments, the first air outlet 115 has a grille structure.

[0044] Furthermore, the grid spacing of the first air outlet 115 is less than or equal to 5 mm. Thus, by configuring the grid structure, the overall airflow can be increased through the multiple grids, and by controlling the grid spacing, insects and rodents can be prevented from entering the electrical control unit 10 through the waterproof cover 11 and damaging the electronic components 122.

[0045] It should be noted that the flexible connection portion 113 includes a plurality of sub-connection portions arranged at intervals, and there is a hollow portion between adjacent sub-connection portions. The hollow portion can further increase the air output of the air outlet and promote heat dissipation.

[0046] In some embodiments, the first air inlet 114 and the first air outlet 115 are oriented in the same direction, so as to prevent rainwater from flowing back into the waterproof cover 11 when the fan blades in the outdoor unit 1 rotate.

[0047] In some embodiments, see Figure 3 , the waterproof cover 11 has an L-shaped structure. Specifically, when the waterproof cover 11 is installed on the electrical control box 12 and used in the outdoor unit 1, the waterproof cover 11 is in the shape of a "factory" or a "7". It should be noted that the first cover shell 111 is L-shaped, and the second cover shell 112 is L-shaped. The waterproof cover 11 with an L-shaped structure includes a first cover segment and a second cover segment that are obliquely connected, and the flexible connection part 113 is located on the second cover segment. The first cover segment is provided with a first air inlet 114 at one end away from the second cover segment, and the second cover segment is provided with a first air outlet 115, and the openings of the first air inlet 114 and the first air outlet 115 are in the same direction. The L-shaped structure of the waterproof cover 11 can not only effectively prevent water, but also facilitates it to be hung on other components to be assembled for pre-assembly and fixation.

[0048] It can be understood that the first cover section and the second cover section jointly define the airflow channel of the waterproof cover 11. Furthermore, the first cover section is arranged at an angle from the first air inlet 114 to the second cover section, so as to facilitate guiding the airflow entering the first air inlet 114 so that it enters the second cover section and then flows out from the first air outlet 115.

[0049] Second, see Figure 4 and Figure 5 The embodiment of the present application further provides an electric control component 10 , which includes an electric control box 12 and the above-mentioned waterproof cover 11 , wherein the waterproof cover 11 is fixedly connected to the outer wall of the electric control box 12 and covers the ventilation opening of the electric control box 12 .

[0050] In some embodiments, when the first fixing portion 1111 and the second fixing portion 1121 are fixedly connected, the first housing 111 and the second housing 112 jointly define a first air inlet 114. The ventilation opening includes a second air outlet 121 disposed on the circumferential outer wall of the electrical control box 12. The second air outlet 121 is in communication with the first air inlet 114. It will be appreciated that the first air inlet 114 is larger than the second air outlet 121. In other words, the first air inlet 114 can completely cover the second air outlet 121 on the outer wall of the electrical control box 12, preventing any gaps from allowing rainwater or insects to enter the electrical control box 12 and damage the electronic components 122.

[0051] In some embodiments, a second air inlet is further provided on a side of the electrical control box 12 away from the second air outlet 121, and the second air inlet is in communication with the second air outlet 121. The electrical control box 12 contains electronic components 122 for controlling the electrical system of the appliance. When in operation, the electronic components 122 generate heat, heating the hot air within the electrical control box 12. Cool air then enters through the second air inlet and exchanges heat with the hot air within the electrical control box 12. The hot air then flows out sequentially through the first air inlet 114 and the first air outlet 115 of the waterproof cover 11, carrying away the heat generated by the electronic components 122, thereby dissipating heat from the electronic components 122 and ensuring the normal operation of the appliance.

[0052] In some embodiments, the waterproof cover 11 is further provided with a third fixing portion 116, and the outer wall of the electrical control box 12 is provided with a fourth fixing portion 123. The third fixing portion 116 and the fourth fixing portion 123 are fixedly connected. Furthermore, the third fixing portion 116 is provided around the first air inlet 114, and the fourth fixing portion 123 is provided around the second air outlet 121. The third fixing portion 116 and the fourth fixing portion 123 can be connected using conventional methods known in the art, such as threaded connection, riveting, welding, and gluing.

[0053] It can be understood that when the waterproof cover 11 has an L-shaped structure, the first air outlet 115 of the waterproof cover 11 and the outer wall of the electric control box 12 are spaced apart, so that the electric control component 10 can be hung on other components to be assembled for pre-assembly and fixation.

[0054] In a third aspect, an embodiment of the present application further provides an outdoor unit 1 , which includes the above-mentioned electronic control component 10 .

[0055] In some embodiments, see Figure 6 The outdoor unit 1 includes a middle partition 20, which is provided with a slot 21. The waterproof cover 11 is mounted on the slot 21. Specifically, when assembling the middle partition 20 and the electronic control component 10, the electronic control component 10 is first secured to the slot 21 via the waterproof cover 11. The slot 21 supports the electronic control component 10 and prevents it from falling. A fifth fixing portion 124 is also provided on the circumferential outer wall of the electric control box 12, and a sixth fixing portion 22 is also provided on the middle partition 20. After the waterproof cover 11 is secured to the slot 21, the fifth fixing portion 124 and the sixth fixing portion 22 are then fixedly connected, thereby achieving a stable connection between the electronic control component 10 and the middle partition 20.

[0056] In this solution, the waterproof cover 11 and the electric control box 12 can be assembled first during the sub-assembly, and the waterproof cover 11 and the card slot 21 can be used for hanging when the middle partition 20 is assembled, which reduces the assembly process. The card slot 21 plays a supporting role, further improving the stability of the waterproof cover 11 and preventing the waterproof cover 11 from falling.

[0057] The connection method between the fifth fixing portion 124 and the sixth fixing portion 22 can refer to the connection method between the third fixing portion 116 and the fourth fixing portion 123 described above, and will not be repeated here.

[0058] In some embodiments, the waterproof cover 11 is provided with a first air outlet 115, which is spaced apart from the middle partition 20. Furthermore, the middle partition 20 is positioned in close contact with the outer wall of the waterproof cover 11. This facilitates smooth air flow from the first air outlet 115 and prevents the middle partition 20 from blocking the first air outlet 115.

[0059] In some embodiments, the waterproof cover 11 comprises a first cover section and a second cover section in an L-shaped connection structure. The first cover section is connected to the ventilation opening of the electrical control box and is mounted in the slot 21. The second cover section is spaced apart from the electrical control box and located on opposite sides of the middle partition. Furthermore, the first air outlet 115 is positioned toward the middle partition 20 to prevent rainwater from entering the electrical control box 12 through the first air outlet 115.

[0060] In some embodiments, see Figure 7 The middle partition 20 separates the outdoor unit 1 into a fan chamber 31 and a compressor chamber 32, and the compressor chamber 32, the electric control box 12, the waterproof cover 11 and the fan chamber 31 are connected in sequence.

[0061] Specifically, the outdoor unit 1 further includes a housing 30. The middle partition 20 is located within the housing 30 and, together with the housing 30, defines a fan chamber 31 and a compressor chamber 32. It will be understood that a fan is located within the fan chamber 31, and a compressor is located within the compressor chamber 32. A third air inlet 33 is provided in the lower middle portion of the housing 30 defining the compressor chamber 32, for allowing external air to enter the compressor chamber 32. The electrical control box 12 is located in the upper middle portion of the compressor chamber 32, and the second air inlet of the electrical control box 12 is located at the bottom of the electrical control box 12. The rotation of the fan in the fan chamber 31 drives the air flow, and the gas entering the compressor chamber 32 through the third air inlet 33 rises, enters the interior of the electric control box 12 through the second air inlet, takes away the heat of the electronic components 122, and then enters the waterproof cover 11 through the second air outlet 121 and the first air inlet 114, and then flows out from the first air outlet 115 and enters the fan chamber 31, thereby realizing heat dissipation of the electronic components 122 and ensuring the smooth operation of the electronic components 122.

[0062] The airflow needs to go through multiple bends from entering the electric control box 12 to flowing out of the waterproof cover 11. The airflow channel forms a maze loop, which can fully prevent rainwater from flowing back when the fan is rotating, thereby achieving a waterproof effect on the electric control box 12.

[0063] An embodiment of the present application further provides an air conditioner, which includes the outdoor unit 1 described above.

[0064] The basic concepts have been described above. It will be apparent to those skilled in the art that the detailed disclosure above is merely illustrative and does not limit the present application. Although not explicitly stated herein, those skilled in the art may make various modifications, improvements, and amendments to the present application. Such modifications, improvements, and amendments are suggested in the present application and remain within the spirit and scope of the exemplary embodiments of the present application.
