Moreover, for machines in areas with strong winds and sand or machines after long-term operation, there is a lot of dust inside the machines. However, in order to prevent water from entering the electric control box, users cannot directly rinse the machines with clean water, resulting in inconvenient cleaning. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is to provide an electric control box with a waterproof function to improve safety and facilitate users to clean the integral air conditioner.

[0004] The technical solution for the embodiments of the present invention to solve the above technical problem is as follows: An electric control box, the electric control box includes: a box body, including a box body and a box cover, the box body includes a box bottom and a side wall connected to the box bottom, the side wall is provided with at least one avoidance notch, and the avoidance notch penetrates the side wall along the thickness direction of the side wall; the box cover seals the top opening of the box body and is connected to the box body; a waterproof sealing structure, provided on the box body, including at least one waterproof seal, and the waterproof sealing structure is configured to seal the gap between the avoidance notch and the component passing through the avoidance notch.

[0005] The beneficial effects of the embodiments of the present invention are as follows: The electric control box provided by the embodiments of the present invention includes a box body and a waterproof sealing structure. The box body includes a box body and a box cover, the box body includes a box bottom and a side wall, and the upper end of the side wall encloses a top opening. The box cover can seal the top opening of the box body, thereby realizing the sealing of the top of the box body. The waterproof sealing structure can seal the gap between the avoidance notch on the side of the box body and the structure passing through the avoidance notch, thereby realizing the sealing of the side of the box body. It can be understood that external liquids such as condensate, rainwater, and cleaning water can only enter the electric control box from the top or side of the box body, and cannot enter the electric control box from the bottom of the box body against gravity. Therefore, the electric control box provided by the embodiments of the present application has good waterproof performance, which can not only prevent condensate or rainwater from entering the electric control box, thereby improving the safety of the electric control box, but also prevent cleaning water from entering the electric control box, thereby facilitating users to directly rinse integral air conditioners such as window air conditioners or mobile air conditioners, and improving the cleaning convenience of integral air conditioners such as window air conditioners or mobile air conditioners.

[0006] Based on the above technical solutions, the present invention can be further improved as follows.

[0007] Furthermore, at least one of the avoidance notches includes a line avoidance notch, and the component is arranged to include a connection line passing through the line avoidance notch; at least one of the waterproof seals includes a first waterproof seal arranged at the line avoidance notch.

[0008] The beneficial effect of adopting the above further solution is that by providing at least one waterproof flexible member at the line avoidance notch, it can effectively prevent water from entering at the line avoidance notch, thereby improving the waterproof performance of the electric control box.

[0009] Furthermore, the first waterproof seal is a first waterproof flexible member, and the first waterproof flexible member is provided with a wire passing gap for the connection line to pass through.

[0010] The beneficial effect of adopting the above further solution is that the waterproof seal arranged at the line avoidance notch uses a first waterproof flexible member, which not only has good waterproof performance but also can undergo a certain amount of elastic deformation. Therefore, it can seal the gap between the connection line and the line avoidance notch and effectively prevent water from entering at the line avoidance notch. By opening a wire passing gap on the first waterproof flexible member, it not only ensures that the connection line can pass through the first waterproof flexible member and extend outside the box to realize the connection between the connection line and the external structure, but also facilitates using the elastic deformation ability of the first waterproof flexible member to seal the wire passing gap and prevent water from entering at the wire passing gap.

[0011] Furthermore, the box cover is provided with a connection line fixing structure, and the connection line fixing structure includes at least two rows of wire dividing plates arranged at intervals. The first waterproof flexible member is clamped and fixed between two adjacent rows of the wire dividing plates; and / or, one of the first waterproof flexible member and the box body is provided with a first convex, and the other is provided with a first slot that is snap-fitted with the first convex.

[0012] The beneficial effect of adopting the above further solution is that it is beneficial to the circuit layout of the electric control box and improves the safety of the electric control box. The connection line fixing structure includes at least two rows of wire dividing plates arranged at intervals. The wire dividing plates are provided with wire dividing grooves for the connection lines to pass through, which can guide and fix multiple groups of connection lines. By using two adjacent rows of wire dividing plates to clamp the first waterproof flexible member, the fixation of the first waterproof flexible member can be achieved without the need to additionally set other structures. The structure is simple, which is beneficial to reducing the production cost of the box body; and during assembly, only the first waterproof flexible member needs to be inserted between two adjacent rows of wire dividing plates, which is convenient for assembly and beneficial to improving the assembly efficiency.

[0013] During assembly, embedding the first clamping projection into the first clamping groove can play a good role in fixing the first waterproof flexible part, preventing the first waterproof flexible part from shifting, falling off, etc., and improving the stability and reliability of the first waterproof flexible part. On the other hand, the cooperation between the first clamping projection and the first clamping groove can also play a role in assembling and positioning the first waterproof flexible part, preventing the first waterproof flexible part from being over-pressed, which is beneficial to improving the service life of the first waterproof flexibility.

[0014] In addition, when the first waterproof flexible part is clamped and fixed between two adjacent rows of wire distributing boards and fixed through the clamping connection between the first clamping projection and the first clamping groove, the first waterproof flexible part obtains the double fixing effects of clamping and fixing and clamping connection, so it has higher stability and reliability.

[0015] Furthermore, at least one of the avoidance notches includes a pipeline avoidance opening, and the component is arranged to include a pipeline passing through the pipeline avoidance opening; at least one of the waterproof seals includes a second waterproof seal arranged at the pipeline avoidance opening.

[0016] The beneficial effect of adopting the above further scheme is that arranging at least one waterproof seal at the pipeline avoidance opening can effectively prevent water from entering at the pipeline avoidance opening, thereby improving the waterproof performance of the electric control box.

[0017] Furthermore, the second waterproof seal is a second waterproof flexible part, and the second waterproof flexible part is provided with a pipeline through hole for the pipeline to pass through.

[0018] The beneficial effect of adopting the above further scheme is that the waterproof seal arranged at the pipeline avoidance opening adopts a second waterproof flexible part, which not only has good waterproof performance but also can undergo a certain amount of elastic deformation. Therefore, it can seal the gap between the pipeline and the pipeline avoidance opening and effectively prevent water from entering at the pipeline avoidance opening. And opening a pipeline through hole in the second waterproof flexible part not only ensures that the pipeline can pass through the second waterproof flexible part and extend out of the box body to realize the connection between the pipeline and the external pipeline, but also facilitates using the elastic deformation ability of the second waterproof flexible part to seal the pipeline through hole and prevent water from entering at the pipeline through hole.

[0019] Furthermore, the second waterproof flexible part includes a first waterproof seal part and a second waterproof seal part. The first waterproof seal part is provided with a first limiting groove for the pipeline to pass through, and the second waterproof seal part is provided with a second limiting groove for the pipeline to pass through. The first limiting groove and the second limiting groove are combined to form the pipeline through hole.

[0020] The beneficial effect of adopting the above further solution is that the second waterproof flexible part is split into two parts, and the first limiting groove and the second limiting groove are combined to form a pipeline through-hole, which not only facilitates the pipeline to easily pass through the second waterproof flexible part and extend out of the box body to realize the connection with the external pipeline, but also can play a good fixing role on the pipeline, preventing the pipeline from shaking to generate noise or shifting to affect the reliability.

[0021] Further, the box cover is provided with two oppositely arranged baffles, and the first waterproof sealing part is clamped and fixed between the two baffles; and / or, the box body is provided with a limiting groove, and the second waterproof sealing part is embedded in the limiting groove.

[0022] The beneficial effect of adopting the above further solution is that the first waterproof sealing part can be fixed by using two baffles to clamp it, the structure is simple, which is beneficial to reducing the production cost of the box body; and during assembly, only the first waterproof sealing part needs to be inserted between the two baffles, and the assembly is convenient, which is beneficial to improving the assembly efficiency.

[0023] A limiting groove is provided on the box body, and the limiting groove can play a role in limiting and fixing the second waterproof sealing part; and during assembly, only the second waterproof sealing part needs to be inserted into the limiting sealing groove, and the assembly is also relatively convenient, which is beneficial to improving the assembly efficiency.

[0024] Further, one of the second waterproof flexible part and the box body is provided with a second convex, and the other is provided with a second groove that is in snap-fit with the second convex.

[0025] The beneficial effect of adopting the above further solution is that during assembly, the second convex is embedded into the second groove, which can play a good fixing role on the second waterproof flexible part, preventing the second waterproof flexible part from shifting, falling off, etc., and improving the stability and reliability of the second waterproof flexible part. On the other hand, the cooperation between the second convex and the second groove can also play a role in assembling and positioning the second waterproof flexible part, preventing the second waterproof flexible part from being over-pressed, which is beneficial to improving the service life of the second waterproof flexibility.

[0026] Further, at least one of the waterproof sealing parts includes a first sealing ring, and the box cover and / or the box body is provided with a sealing groove, the sealing groove is arranged along the circumference of the box cover, and the first sealing ring is embedded in the sealing groove.

[0027] The beneficial effect of adopting the above further solution is that it is beneficial to prevent water from entering the box body from the gap between the box cover and the box body, and can circumferentially seal the side part of the box body, thereby further improving the sealing performance and waterproof performance of the electric control box.

[0028] Further, part or all of at least one of the avoidance notches penetrates the top end of the side wall portion, and the waterproof seal at the avoidance notch penetrating the top end of the side wall portion abuts against the first sealing ring.

[0029] The beneficial effect of adopting the above further solution is that when the avoidance notch penetrates the top end of the side wall portion, the avoidance notch is convenient for processing and has a relatively large size, which is convenient for the assembly of connecting wires, pipelines and the waterproof seal at this part. The waterproof seals at these parts abut against the first sealing ring, which can prevent liquid from entering the box body along the top of the avoidance notch, which is beneficial to reducing the size of the waterproof seal at this part. For example, the waterproof seal at this part does not need to block the top of the avoidance notch, but can use the cover edge of the box cover and other structures to block the top of the avoidance notch, thereby reducing the production cost of the waterproof seal at this part.

[0030] Further, a heat dissipation notch is provided at the bottom of the box, and the electronic control box includes an air-cooled radiator passing through the heat dissipation notch; at least one of the waterproof seals includes a second sealing ring, and the second sealing ring is sleeved on the air-cooled radiator and seals the gap between the air-cooled radiator and the heat dissipation notch; and / or, a heat dissipation hole is provided at the bottom of the box, and a water blocking structure corresponding to the heat dissipation hole is provided on the inner surface of the box body.

[0031] The beneficial effect of adopting the above further solution is that an air-cooled radiator is provided in the box body. One end of the air-cooled radiator is in direct or indirect contact with the electronic control board, and the other end of the air-cooled radiator passes through the heat dissipation notch and extends out of the box body, which can timely export the heat of the electronic control board to the outside of the box body to dissipate heat from the electronic control board. A second sealing ring is provided at the heat dissipation notch, which can seal the gap between the air-cooled radiator and the heat dissipation notch, and improve the sealing performance and waterproof performance of the bottom of the box while taking into account the heat dissipation performance.

[0032] Providing a heat dissipation hole at the bottom of the box can increase the path of heat dissipation in the electronic control box, which is beneficial to further improving the heat dissipation effect. Providing a water blocking structure on the inner surface of the box body is beneficial to preventing liquid from entering the electronic control box from the heat dissipation hole, so the waterproof performance of the bottom of the box is improved while taking into account the heat dissipation performance.

[0033] Further, the box cover includes an inner cover and an outer cover, the outer cover is sleeved outside the inner cover, the inner cover is a plastic part, and the outer cover is a metal part.

[0034] The beneficial effect of adopting the above further solution is that the inner cover is made of a plastic part, such as an injection molded part, which has a waterproof function and also plays a fixing and supporting role. The outer cover is made of a metal part, such as a sheet metal formed part, which has waterproof and fireproof functions and also plays a fixing and supporting role, and is also beneficial to the heat dissipation of the electronic control box.

[0035] Further, a support step is provided on the inner surface of the box body; the inner cover abuts against the support step.

[0036] The beneficial effect of adopting the above further solution is that the support step can play an assembly and positioning role for the inner cover, thereby improving the assembly efficiency and also improving the stability of the inner cover.

[0037] The technical problem to be solved by the embodiment of the present invention is to provide a window air conditioner with a waterproof function for the electric control box to facilitate user cleaning.

Detailed implementation manner

[0061] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0062] As Figure 1 shown, an embodiment of the present invention provides an electric control box 100. The electric control box 100 includes: a box body 1 and a waterproof sealing structure 2.

[0063] Specifically, as Figure 1 shown, the box body 1 includes a box body 11 and a box cover 12. The box body 11 includes a box bottom 111 and a side wall 112, and the side wall 112 is connected to the box bottom 111. The side wall 112 is provided with at least one avoidance notch 113 (as Figure 4 shown). The avoidance notch 113 penetrates the side wall 112 along the thickness direction of the side wall 112. The box cover 12 covers the top opening of the box body 11 and is connected to the box body 11, as Figure 1 shown.

[0064] The waterproof sealing structure 2 is provided on the box body 1, as Figure 1 shown. The waterproof sealing structure 2 includes at least one waterproof seal 21 (as Figure 7 shown). The waterproof sealing structure 2 seals the gap between the avoidance notch 113 and the member passing through the avoidance notch 113.

[0065] The electric control box 100 provided by an embodiment of the present invention includes a box body 1 and a waterproof sealing structure 2. The box body 1 includes a box body 11 and a box cover 12. The box body 11 includes a box bottom 111 and a side enclosure 112. The upper end of the side enclosure 112 encloses a top opening, and the box cover 12 can seal the top opening of the box body 11, thereby realizing the sealing of the top of the box body 1. The waterproof sealing structure 2 can seal the gap between the avoidance notch 113 on the side of the box body 1 and the structure passing through the avoidance notch 113, thereby realizing the sealing of the side of the box body 1. It can be understood that external liquids such as condensed water, rainwater, and cleaning water can only enter the electric control box 100 from the top or side of the box body 1, and cannot enter the electric control box 100 from the bottom of the box body 1 against gravity. Therefore, the electric control box 100 provided by the embodiment of the present application has good waterproof performance, which can not only prevent condensed water or rainwater from entering the electric control box 100, thereby improving the safety of the electric control box 100, but also prevent cleaning water from entering the electric control box 100, thereby facilitating the user to directly wash the window air conditioner 200 or integral air conditioners such as a mobile air conditioner, and improving the cleaning convenience of the window air conditioner 200 or integral air conditioners such as a mobile air conditioner.

[0066] In a schematic embodiment, as Figure 4 shown, the box body 11 adopts a double-layer structure inside and outside, including an inner shell 116 and an outer shell 117. The outer shell 117 is sleeved outside the inner shell 116. The inner shell 116 is a plastic part, which can play a role in waterproofing and fixed support. The outer shell 117 is a metal part, which can play a role in waterproofing, fireproofing and fixed support, and is also beneficial to the heat dissipation of the electric control box 100. The inner shell 116 includes an inner bottom plate 1111 and an inner enclosure plate 1121 connected to the inner bottom plate 1111. The outer shell 117 includes an outer bottom plate 1112 and an outer enclosure plate 1122 connected to the outer bottom plate 1112. The side enclosure 112 of the box body 11 includes the inner enclosure plate 1121 of the inner shell 116 and the outer enclosure plate 1122 of the outer shell 117. The box bottom 111 of the box body 11 includes the inner bottom plate 1111 of the inner shell 116 and the outer bottom plate 1112 of the outer shell 117. The avoidance notch 113 includes an inner notch 1133 provided on the inner enclosure plate 1121 and an outer notch 1134 provided on the outer enclosure plate 1122. The inner notch 1133 and the outer notch 1134 are correspondingly communicated to ensure that structures such as connection lines and pipelines can extend from inside the box body 1 to outside the box body 1, and then be connected to other structures outside the box body 1.

[0067] Wherein, the inner enclosure plate 1121 can also be provided with a hollowed-out heat dissipation opening to improve the heat dissipation performance of the electric control box 100, and the corresponding position of the outer enclosure plate 1122 is closed to ensure that there is no avoidance notch 113 in the side enclosure 112 of this part, so there is no need to provide a waterproof sealing structure 2 at this part.

[0068] Furthermore, at least one of the avoidance notches 113 is a line avoidance opening 1131, as Figure 8As shown. The component includes a connecting wire (not shown in the figure) passing through the wire avoidance opening 1131. At least one of the waterproof seals 21 is provided at the wire avoidance opening 1131, such as Figure 7 As shown.

[0069] In a schematic embodiment, such as Figure 7 As shown, two avoidance notches 113 are wire avoidance openings 1131. The two wire avoidance openings 1131 are respectively provided at both ends in the length direction of the box body 1. One waterproof seal 21 is correspondingly provided at each avoidance notch 113.

[0070] Of course, two or more waterproof seals 21 can also be provided at one avoidance notch 113, as long as the normal installation of the wire and waterproof sealing are ensured.

[0071] An electronic control board 5 is installed in the box body 1 of the electronic control box 100 (as Figure 11 shown). The electronic control board 5 is electrically connected to other structures outside the electronic control box 100 (such as structures like the compressor 230, the indoor-side fan 220, the outdoor-side fan 210, etc., see Figure 11 and Figure 12 ) through a connecting wire to control the window air conditioner 200. Therefore, a wire avoidance opening 1131 is usually provided on the box body 1 of the electronic control box 100, and the unsealed wire avoidance opening 1131 is an important reason for water ingress into the electronic control box 100. Therefore, in this embodiment, at least one waterproof seal 21 is provided at the wire avoidance opening 1131, which can effectively prevent water from entering at the wire avoidance opening 1131, thereby improving the waterproof performance of the electronic control box 100.

[0072] Further, the waterproof seal 21 provided at the wire avoidance opening 1131 is denoted as the first waterproof flexible member 211, such as Figure 6 shown. The first waterproof flexible member 211 is provided with a wire passing gap 2111 for the connecting wire to pass through.

[0073] The waterproof seal 21 provided at the wire avoidance opening 1131 adopts the first waterproof flexible member 211, which not only has good waterproof performance but also can undergo a certain amount of elastic deformation. Therefore, it can seal the gap between the connecting wire and the wire avoidance opening 1131 and effectively prevent water from entering at the wire avoidance opening 1131.

[0074] And a wire passing gap 2111 is opened on the first waterproof flexible member 211, which not only ensures that the connecting wire can pass through the first waterproof flexible member 211 and extend outside the box body 1 to realize the connection between the connecting wire and the external structure, but also facilitates using the elastic deformation ability of the first waterproof flexible member 211 to seal the wire passing gap 2111 and prevent water from entering at the wire passing gap 2111.

[0075] Among them, the first waterproof flexible member 211 is a silicone member or a PVC (Polyvinyl chloride) sponge, which has a low cost. Other materials with waterproofness and flexible deformation ability can also be used.

[0076] In a schematic embodiment, as Figure 8 shown, the number of the line avoidance openings 1131 is two, and a first waterproof flexible member 211 is respectively provided at the two line avoidance openings 1131. The number of the wire passing slits 2111 on the first waterproof flexible member 211 is four, and the four wire passing slits 2111 are arranged at intervals. The number of the wire passing slits 2111 on the other first waterproof flexible member 211 is two, and the two wire passing slits 2111 are arranged at intervals.

[0077] Further, one end of the wire passing slit 2111 close to the bottom 111 of the box penetrates through the first waterproof flexible member 211, as Figure 8 shown.

[0078] One end of the wire passing slit 2111 close to the bottom 111 of the box penetrates through the first waterproof flexible member 211 to form an entrance of the wire passing slit 2111. When assembling the connecting wire, there is no need to hold the end of the connecting wire and pass it through the wire passing slit 2111 and then pull it to the corresponding length. Instead, the connecting wire can be directly pulled to the corresponding length and then stuffed into the wire passing slit 2111 along the entrance of the wire passing slit 2111. In this way, the assembly difficulty between the connecting wire and the first waterproof flexible member 211 is significantly reduced, thereby improving the assembly efficiency.

[0079] Moreover, when processing the wire passing slit 2111, the tool can be set to draw out from the set position of the first waterproof flexible member 211 along the set direction, so the processing difficulty of the first waterproof flexible member 211 is also reduced.

[0080] Further, a guiding structure 2112 is provided at the open end of the wire passing slit 2111, as Figure 8 shown. The guiding structure 2112 can play a guiding role in the assembly between the connecting wire and the first waterproof flexible member 211, which is beneficial to the quick assembly in place between the connecting wire and the first waterproof flexible member 211, thereby improving the assembly efficiency.

[0081] Among them, the guiding structure 2112 can adopt structures such as an arc-shaped opening and a trapezoidal opening, so that the width of the open end of the wire passing slit 2111 becomes smaller from large, so as to facilitate the connecting wire to quickly enter the wire passing slit 2111.

[0082] In a schematic embodiment of the present invention, further, refer to Figure 2 、 Figure 4 and Figure 5As shown, the box cover 12 is provided with a connecting wire fixing structure 121, and the connecting wire fixing structure 121 includes at least two rows of wire dividing plates 1211 arranged at intervals. The first waterproof flexible member 211 is clamped and fixed between two adjacent rows of wire dividing plates 1211.

[0083] By providing the connecting wire fixing structure 121 on the box cover 12, the connecting wires inside the box body 1 can be guided, classified (such as separating the strong wires and weak wires), and fixed, which is beneficial to the circuit layout of the electric control box 100 and improves the safety of the electric control box 100.

[0084] The connecting wire fixing structure 121 includes at least two rows of wire dividing plates 1211 arranged at intervals, and the wire dividing plates 1211 are provided with wire dividing grooves 1212 (as Figure 5 shown) for the connecting wires to pass through, which can guide and fix multiple groups of connecting wires. By using two adjacent rows of wire dividing plates 1211 to clamp the first waterproof flexible member 211, the fixing of the first waterproof flexible member 211 can be achieved without additionally setting fixing structures such as fasteners, and the structure is simple, which is beneficial to reducing the production cost of the box body 1.

[0085] In addition, during assembly, only the first waterproof flexible member 211 needs to be inserted between two adjacent rows of wire dividing plates 1211, and the assembly is convenient, which is beneficial to improving the assembly efficiency.

[0086] Among them, the connecting wire fixing structure 121 may further include structures such as wire winding posts, wire straightening ribs, and hooks.

[0087] In a schematic embodiment of the present invention, further, one of the first waterproof flexible member 211 and the box body 1 is provided with a first convex 2113 (as Figure 3 and Figure 6 shown), and the other is provided with a first slot 122 that is snap-fitted with the first convex 2113 (as Figure 3 and Figure 5 shown).

[0088] The first convex 2113 is provided on the first waterproof flexible member 211, and the first slot 122 is correspondingly provided on the box body 1; or the positions of the first convex 2113 and the first slot 122 can also be swapped, with the first convex 2113 provided on the box body 1 and the first slot 122 provided on the first waterproof flexible member 211. During assembly, by inserting the first convex 2113 into the first slot 122, a good fixing effect on the first waterproof flexible member 211 can be achieved, preventing the first waterproof flexible member 211 from shifting, falling off, etc., and improving the stability and reliability of the first waterproof flexible member 211.

[0089] On the other hand, when the first card projection 2113 and the first card slot 122 are engaged, it indicates that the first waterproof flexible member 211 is assembled in place. Therefore, the engagement between the first card projection 2113 and the first card slot 122 can also play a role in assembling and positioning the first waterproof flexible member 211, preventing the first waterproof flexible member 211 from being over-pressed, thereby contributing to improving the lifespan of the first waterproof flexibility.

[0090] In addition, when the first waterproof flexible member 211 is clamped and fixed between two adjacent rows of wire dividing plates 1211 and fixed through the snap-fit between the first card projection 2113 and the first card slot 122, the first waterproof flexible member 211 obtains the dual fixing effects of clamping and fixing and snap-fixing, and thus has higher stability and reliability.

[0091] Among them, the first card projection 2113 or the first card slot 122 provided on the box body 1 can be provided on the box cover 12 of the box body 1 or on the box body 11 of the box body 1. The number of the first card projections 2113 can be one, or two or more; the number of the first card slots 122 is equal to and corresponds one by one to the number of the first card projections 2113.

[0092] In a schematic embodiment, the first card projection 2113 is provided on the first waterproof flexible member 211, as Figure 6 and Figure 8 shown. The first card slot 122 is provided on the box cover 12, specifically on the wire dividing plate 1211 of the box cover 12, as Figure 5 shown. Moreover, the first card slots 122 are provided on both rows of wire dividing plates 1211, and the corresponding two sides of the first waterproof flexible member 211 are both provided with the first card projections 2113 (as Figure 8 shown), which is conducive to the balanced force of the first waterproof flexible member 211. During the assembly process, the first waterproof flexible member 211 is inserted between the two rows of wire dividing plates 1211 until the first card projections 2113 on both sides are snapped into the first card slots 122.

[0093] In a schematic embodiment of the present invention, as Figure 6 shown, the first waterproof flexible member 211 includes a first side plate portion 2114, a middle limiting portion 2115, and a second side plate portion 2116, and the first side plate portion 2114, the middle limiting portion 2115, and the second side plate portion 2116 are sequentially connected along the threading direction of the connection line. The middle limiting portion 2115 includes at least one limiting convex portion 2117, as Figure 6 shown. At least one limiting concave portion 1135 is provided at the line avoidance opening 1131, in combination with Figure 4 , Figure 6 and Figure 9 shown. The limiting convex portion 2117 and the limiting concave portion 1135 are in concave-convex fit. The limiting concave portion 1135 is specifically provided at the inner side notch 1133 of the inner shell 116.

[0094] In this way, after assembly, the cooperation between the limiting convex part 2117 and the limiting concave part 1135 can play a better role in limiting and fixing the first waterproof flexible part 211, effectively ensuring the stability and reliability of the first waterproof flexible part 211. In addition, the first side plate part 2114 and the second side plate part 2116 are clamped on the inner and outer sides of the inner notch 1133, which can further improve the waterproof performance.

[0095] In a schematic embodiment, the number of the limiting convex parts 2117 is multiple, the limiting convex parts 2117 are in a cylindrical shape or a semi-cylindrical shape, the number of the limiting concave parts 1135 is equal to and corresponds to the number of the limiting convex parts 2117 one by one, and the limiting concave parts 1135 are in a semi-cylindrical shape.

[0096] Among them, the larger-sized first waterproof flexible part 211 includes four limiting convex parts 2117, and the smaller-sized first waterproof flexible part 211 includes two limiting convex parts 2117.

[0097] In a schematic embodiment of the present invention, further, at least one of the avoidance notches 113 is a pipeline avoidance opening 1132, as Figure 7 shown. The component includes a pipeline (such as the refrigerant pipe 41 as Figure 4 shown) passing through the pipeline avoidance opening 1132. At least one of the waterproof seals 21 is arranged at the pipeline avoidance opening 1132, as Figure 7 shown.

[0098] The electric control box 100 includes a pipeline, the pipeline can be the refrigerant pipe 41, and the refrigerant pipe 41 can be connected to the refrigerant flow path of the window air conditioner 200 to cool the heating elements in the electric control box 100 by using the cold quantity of the system refrigerant and take away the heat in the electric control box 100, so as to dissipate the heat of the electric control box 100. Therefore, a pipeline avoidance opening 1132 needs to be opened on the box body 1 of the electric control box 100. In this embodiment, at least one waterproof seal 21 is arranged at the pipeline avoidance opening 1132, which can effectively prevent water from entering at the pipeline avoidance opening 1132, thereby improving the waterproof performance of the electric control box 100.

[0099] In a schematic embodiment, as Figure 8 shown, the top opening of the box body 11 is generally rectangular. The number of the line avoidance openings 1131 is two, and the number of the pipeline avoidance openings 1132 is one. The pipeline avoidance opening 1132 and the two line avoidance openings 1131 both penetrate through the top end of the side wall part 112. The size of one of the line avoidance openings 1131 is relatively large, and this line avoidance opening 1131 is arranged at one end of the side wall part 112 in the length direction. The size of the other line avoidance opening 1131 is relatively small, and this line avoidance opening 1131 and the pipeline avoidance opening 1132 are both arranged at the other end of the side wall part 112 in the length direction and are arranged at intervals.

[0100] Further, the electronic control box 100 may further include a refrigerant heat sink 42, and the refrigerant heat sink 42 is sleeved on the refrigerant pipe 41. The refrigerant heat sink 42 may adopt a structure with good thermal conductivity such as an aluminum plate to further improve the heat dissipation effect. The refrigerant heat sink 42 and the refrigerant heat dissipation pipe are combined to form a refrigerant radiator 4, and the refrigerant radiator 4 can use the system refrigerant to dissipate heat from the heating elements in the electronic control box 100.

[0101] Further, the waterproof seal 21 provided at the pipe avoiding opening 1132 is denoted as the second waterproof flexible member 212, and the second waterproof flexible member 212 is provided with a pipe through hole 2123 for the pipe to pass through (as Figure 6 shown).

[0102] The waterproof seal 21 provided at the pipe avoiding opening 1132 adopts the second waterproof flexible member 212, which has good waterproof performance and can undergo a certain amount of elastic deformation. Therefore, it can seal the gap between the pipe and the pipe avoiding opening 1132 and effectively prevent water from entering at the pipe avoiding opening 1132.

[0103] And by opening the pipe through hole 2123 in the second waterproof flexible member 212, it not only ensures that the pipe can pass through the second waterproof flexible member 212 and extend out of the box body 1 to realize the connection with the external pipe, but also facilitates using the elastic deformation ability of the second waterproof flexible member 212 to seal the pipe through hole 2123 and prevent water from entering at the pipe through hole 2123.

[0104] In a schematic embodiment, further, the second waterproof flexible member 212 includes a first waterproof sealing portion 2121 and a second waterproof sealing portion 2122, as Figure 6 shown. The first waterproof sealing portion 2121 is provided with a first limiting groove 2124 for the pipe to pass through. The second waterproof sealing portion 2122 is provided with a second limiting groove 2125 for the pipe to pass through. The first limiting groove 2124 and the second limiting groove 2125 are combined to form the pipe through hole 2123, as Figure 6 shown.

[0105] Since the pipe is thicker than the connecting wire, the second waterproof flexible member 212 is split into two parts, and the pipe through hole 2123 is formed by combining the first limiting groove 2124 and the second limiting groove 2125. In this way, it is not only convenient for the pipe to easily pass through the second waterproof flexible member 212 and extend out of the box body 1 to realize the connection with the external pipe, and it can play a good role in fixing the pipe to prevent the pipe from shaking to generate noise or shifting to affect the reliability, but also convenient for the processing and forming of the second waterproof flexible member 212.

[0106] Among them, the second waterproof flexible member 212 is a silicone member or a PVC (Polyvinyl chloride) sponge, which has a low cost. Of course, other materials with waterproofness and flexible deformation ability can also be used.

[0107] Of course, the second waterproof flexible member 212 can also not be split and adopt a complete structure.

[0108] In a schematic embodiment of the present invention, further, the lid 12 is provided with two oppositely arranged baffles (not shown in the figure). The first waterproof sealing portion 2121 is clamped and fixed between the two baffles. The box body 11 is provided with a limiting groove 114, as Figure 6 shown. The second waterproof sealing portion 2122 is embedded in the limiting groove 114.

[0109] By providing two baffles on the lid 12 and using the two baffles to clamp the first waterproof sealing portion 2121, the fixation of the first waterproof sealing portion 2121 can be achieved. The structure is simple, which is beneficial to reducing the production cost of the box body 1; and during assembly, only the first waterproof sealing portion 2121 needs to be inserted between the two baffles, and the assembly is convenient, which is beneficial to improving the assembly efficiency.

[0110] Similarly, by providing a limiting groove 114 on the box body 11, the limiting groove 114 can play a role in limiting and fixing the second waterproof sealing portion 2122; and during assembly, only the second waterproof sealing portion 2122 needs to be inserted into the limiting sealing groove 1151, and the assembly is also relatively convenient, which is beneficial to improving the assembly efficiency.

[0111] In a schematic embodiment, further, one of the second waterproof flexible member 212 and the box body 1 is provided with a second convex 2126 (as Figure 6 shown), and the other is provided with a second slot 124 that is in snap-fit with the second convex 2126 (as Figure 6 shown).

[0112] By providing a second convex 2126 on the second waterproof flexible member 212 and correspondingly providing a second slot 124 on the box body 1, or the positions of the second convex 2126 and the second slot 124 can also be swapped, with the second convex 2126 provided on the box body 1 and the second slot 124 provided on the second waterproof flexible member 212. During assembly, by inserting the second convex 2126 into the second slot 124, a good fixing effect can be achieved on the second waterproof flexible member 212, preventing the second waterproof flexible member 212 from shifting, falling off, etc., and improving the stability and reliability of the second waterproof flexible member 212.

[0113] On the other hand, when the second card projection 2126 and the second card slot 124 are engaged, it indicates that the second waterproof flexible member 212 is assembled in place. Therefore, the engagement between the second card projection 2126 and the second card slot 124 can also play a role in assembling and positioning the second waterproof flexible member 212, preventing the second waterproof flexible member 212 from being excessively squeezed, thereby contributing to improving the lifespan of the second waterproof flexibility.

[0114] Among them, the second card projection 2126 or the second card slot 124 provided on the box body 1 can be provided on the lid 12 of the box body 1 or on the body 11 of the box body 1. The number of the second card projections 2126 can be one, or two or more; the number of the second card slots 124 is equal to and corresponds one by one to the number of the second card projections 2126.

[0115] In a schematic embodiment, the first waterproof sealing portion 2121 and the second waterproof sealing portion 2122 of the second waterproof flexible member 212 are both provided with the second card projections 2126, as Figure 6 shown. The lid 12 of the box body 1 is provided with the second card slots 124 corresponding to the first waterproof sealing portion 2121, specifically provided on two baffles of the lid 12, which is beneficial to the balanced force of the first waterproof sealing portion 2121. During the assembly process, insert the first waterproof sealing portion 2121 of the second waterproof flexible member 212 between the two baffles until the second card projection 2126 is snapped into the second card slot 124. The body 11 of the box body 1 is provided with the second card slots 124 corresponding to the second waterproof sealing portion 2122, specifically provided on two opposite side walls of the limiting groove 114, as Figure 6 shown, which is beneficial to the balanced force of the second waterproof sealing portion 2122. Insert the second waterproof sealing portion 2122 of the second waterproof sealing member 21 into the limiting groove 114 until the second card projection 2126 is snapped into the second card slot 124.

[0116] When the first waterproof sealing portion 2121 of the second waterproof flexible member 212 is clamped and fixed between two baffles and fixed by the snap - fit between the second card projection 2126 and the second card slot 124, the first waterproof sealing portion 2121 obtains the dual fixing effects of clamping and snap - fixing, and thus has higher stability and reliability.

[0117] When the second waterproof sealing portion 2122 is inserted into the corresponding limiting groove 114 and fixed by the snap - fit between the second card projection 2126 and the second card slot 124, the second waterproof sealing portion 2122 also obtains the dual fixing effects of clamping and snap - fixing, and thus has higher stability and reliability.

[0118] In a schematic embodiment, the refrigerant pipe 41 is in a U - shape, as Figure 4As shown. The number of the first limiting grooves 2124 and the second limiting grooves 2125 is two each. The two first limiting grooves 2124 and the two second limiting grooves 2125 are combined to form two pipeline through holes 2123, and the two pipeline through holes 2123 correspond to the two ends of the refrigerant pipe 41 one by one.

[0119] In a schematic embodiment of the present invention, further, one of the waterproof seals 21 is a first sealing ring 213, as Figure 4 shown. The lid 12 and / or the box body 11 is provided with a sealing groove 1151 (as Figure 6 and Figure 8 shown). The sealing groove 1151 is arranged along the circumferential direction of the lid 12, and the first sealing ring 213 is embedded in the sealing groove 1151.

[0120] A sealing groove 1151 is arranged in a circle along the inner surface of the lid 12, or a sealing groove 1151 is arranged in a circle along the inner surface of the box body 11, or sealing grooves 1151 are arranged in a circle along the inner surfaces of both the lid 12 and the box body 11, and the sealing groove 1151 of the lid 12 and the sealing groove 1151 of the box body 11 are arranged correspondingly. Installing the first sealing ring 213 in the sealing groove 1151 is beneficial to preventing water from entering the box body 1 through the gap between the lid 12 and the box body 1, and can perform circumferential sealing on the side part of the box body 1, thereby further improving the sealing performance and waterproof performance of the electric control box 100.

[0121] Among them, the sealing groove 1151 provided on the lid 12 can be formed by the cooperation of the lid edge of the lid 12 and a circle of sealing ribs. The sealing groove 1151 provided on the box body 11 can be formed by the cooperation of two circles of sealing ribs. The first sealing ring 213 can be a silica gel ring, a rubber ring or a PVC sponge ring, with low cost. Of course, other materials with waterproof performance and flexible deformation ability can also be used.

[0122] In a schematic embodiment, further, at least one of the avoidance notches 113 penetrates through the top end of the side wall part 112, as Figure 4 shown. The waterproof seal 21 at the avoidance notch 113 penetrating through the top end of the side wall part 112 abuts against the first sealing ring 213.

[0123] The beneficial effects of adopting the above further solution are as follows. When the avoidance notch 113 penetrates through the top end of the side wall portion 112, the avoidance notch 113 is convenient for machining and has a relatively large size, which is convenient for the assembly of pipelines such as connection wires and refrigerant pipes 41 and the waterproof seal 21 at this part. The waterproof seals 21 at these parts are all abutted against the first sealing ring 213, which can prevent liquid from entering the box body 1 along the top of the avoidance notch 113. This is beneficial to reducing the size of the waterproof seal 21 at this part. For example, the waterproof seal 21 at this part does not need to block the top of the avoidance notch 113, but can use structures such as the cover edge of the box cover 12 to block the top of the avoidance notch 113, thereby reducing the production cost of the waterproof seal 21 at this part.

[0124] In a schematic embodiment of the present invention, further, a heat dissipation notch 1113 is provided at the bottom 111 of the box, as Figure 7 shown. The electric control box 100 includes an air-cooled radiator 3 passing through the heat dissipation notch 1113, as Figure 7 shown. One of the waterproof seals 21 is a second sealing ring 214, as Figure 4 and Figure 8 shown. The second sealing ring 214 is sleeved on the air-cooled radiator 3 and seals the gap between the air-cooled radiator 3 and the heat dissipation notch 1113.

[0125] An air-cooled radiator 3 is arranged in the box body 1. One end of the air-cooled radiator 3 is in direct or indirect contact with the electric control board 5, and the other end of the air-cooled radiator 3 passes through the heat dissipation notch 1113 and extends out of the box body 1, which can timely export the heat of the electric control board 5 to the outside of the box body 1 to dissipate heat from the electric control board 5. A second sealing ring 214 is arranged at the heat dissipation notch 1113, which can seal the gap between the air-cooled radiator 3 and the heat dissipation notch 1113, and improve the sealing and waterproof performance of the bottom of the box body 1 on the basis of considering the heat dissipation performance.

[0126] Among them, the air-cooled radiator 3 includes a heat dissipation base 31 and an air-cooled heat dissipation fin 32 connected to the heat dissipation base 31, as Figure 4 shown. The second sealing ring 214 is sleeved on the heat dissipation base 31. The second sealing ring 214 can be a silica gel ring, a rubber ring or a PVC sponge ring, with low cost. Of course, other materials with waterproofness and flexible deformation ability can also be used.

[0127] In a schematic embodiment of the present invention, further, heat dissipation holes 1114 are provided at the bottom 111 of the box, as Figure 7 shown. A water blocking structure 118 corresponding to the heat dissipation holes 1114 is provided on the inner surface of the box body 11, as Figure 8 shown.

[0128] A heat dissipation hole 1114 is provided on the bottom 111 of the box, which can increase the heat dissipation path inside the electronic control box 100 and is beneficial to further improving the heat dissipation effect. A water blocking structure 118 is provided on the inner surface of the box body 11, which is beneficial to preventing liquid from entering the electronic control box 100 through the heat dissipation hole 1114. Therefore, on the basis of considering the heat dissipation performance, the waterproof property of the bottom of the box body 1 is improved.

[0129] Among them, as Figure 8 and Figure 9 shown, the water blocking structure 118 can adopt structures such as a water blocking plate 1181 and a water blocking rib 1182. As Figure 10 shown, the water blocking plate 1181 can be arranged opposite to the heat dissipation hole 1114 to block the liquid entering the box body 1 from bottom to top. The water blocking rib 1182 can be arranged perpendicular to the water blocking plate 1181 to block the liquid entering the box body 1 from flowing further in the horizontal direction or other directions inside the box body 1.

[0130] In a schematic embodiment of the present invention, further, the box cover 12 includes an inner cover 125 and an outer cover 126, as Figure 4 shown. The outer cover 126 is sleeved outside the inner cover 125. The inner cover 125 is a plastic part, and the outer cover 126 is a metal part.

[0131] In this embodiment, the box cover 12 is arranged as a double-layer structure inside and outside. Among them, the inner cover 125 is made of a plastic part, such as an injection molded part, which has a waterproof function and also plays a fixing and supporting role. The outer cover 126 is made of a metal part, such as a sheet metal formed part, which has waterproof and fireproof functions and also plays a fixing and supporting role, and is also beneficial to the heat dissipation of the electronic control box 100. Among them, the aforementioned connection line fixing structure 121, baffle, and sealing groove 1151 provided on the box cover 12 are all provided on the inner cover 125.

[0132] Correspondingly, the box body 11 can also adopt a double-layer structure inside and outside, including an inner shell 116 and an outer shell 117. The inner shell 116 includes an inner bottom plate 1111 and an inner surrounding plate 1121 connected to the inner bottom plate 1111. The outer shell 117 includes an outer bottom plate 1112 and an outer surrounding plate 1122 connected to the outer bottom plate 1112. The side surrounding part 112 of the box body 11 includes the inner surrounding plate 1121 of the aforementioned inner shell 116 and the outer surrounding plate 1122 of the aforementioned outer shell 117. The box bottom 111 of the box body 11 includes the inner bottom plate 1111 of the aforementioned inner shell 116 and the outer bottom plate 1112 of the aforementioned outer shell 117. Among them, the aforementioned limiting groove 114, the sealing groove 1151 provided on the box body 11, and the water blocking structure 118 are all provided on the inner shell 116.

[0133] In a schematic embodiment, heat dissipation holes 1114 are provided on both the inner bottom plate 1111 and the outer bottom plate 1112, as Figure 7 , Figure 8 and Figure 9As shown, the number of heat dissipation holes 1114 in the inner bottom plate 1111 is multiple. For example, Figure 8 as shown, the heat dissipation holes 1114 in the inner bottom plate 1111 are generally rectangular and have a relatively large area. The number of heat dissipation holes 1114 in the outer bottom plate 1112 is also multiple. The heat dissipation holes 1114 in the outer bottom plate 1112 are circular and have a relatively small area. For example, Figure 7 as shown. The multiple heat dissipation holes 1114 in the outer bottom plate 1112 are arranged in an array and distributed in two places. One place can be used as an air inlet, and the other place can be used as an air outlet. In Figure 8 , the place with a larger number of heat dissipation holes 1114 is the air inlet, and the place with a smaller number of heat dissipation holes 1114 is the air outlet.

[0134] The inner shell 116 is provided with the above-mentioned water blocking structure 118. The water blocking structure 118 includes a water blocking plate 1181 and water blocking ribs 1182 corresponding to the air inlet of the electric control box 6. For example, Figure 8 , Figure 9 and Figure 10 as shown. The water blocking structure 118 further includes a water blocking plate 1181 corresponding to the air outlet of the electric control box 6. For example, Figure 8 , Figure 9 and Figure 10 as shown.

[0135] In this way, the electric control box 100 is installed on the air flow path of the outdoor side fan 210 of the window air conditioner 200. For example, Figure 10 and Figure 11 as shown. In Figure 10 and Figure 11 , the small arrow indicates the flow direction of the air flow passing through the electric control box 100, and the large arrow indicates the main flow direction of the air flow of the outdoor side fan 210 of the window air conditioner 200. In this way, the electric control box 100 can use the air flow entering the electric control box 100 from the air inlet and flowing out of the electric control box 100 through the air outlet for heat dissipation, so as to improve the heat dissipation performance of the electric control box 100 and make the bottom of the electric control box 100 waterproof.

[0136] In a schematic embodiment, further, a support step 115 is provided on the inner surface of the box body 11. For example, Figure 6 as shown. The inner cover 125 abuts against the support step 115.

[0137] By providing the support step 115 on the inner surface of the box body 11 to support the inner cover 125, it can play an assembly positioning role for the inner cover 125, thereby improving the assembly efficiency and also improving the stability of the inner cover 125.

[0138] Further, the support step 115 is specifically provided on the inner shell 116 of the box body 11, and the sealing groove 1151 provided on the inner shell 116 is specifically provided on the support step 115.

[0139] Among them, as Figure 4 shown, the inner cover 125 can be provided with connection holes 1251 and fixedly connected to the electronic control board 5 through fasteners such as screws. The inner cover 125 can also be provided with connection posts 1252 and fixedly connected to the inner shell 116 through fasteners such as screws.

[0140] In a schematic embodiment, the inner cover 125 is provided with four connection holes 1251 and two connection posts 1252. The inner cover 125 is fixedly connected to the electronic control board 5 through four screws. The inner cover 125 is fixedly connected to the inner shell 116 through two screws. The outer cover 126 and the outer shell 117 are both provided with convex edges 1261, as Figure 4 shown, and the convex edges 1261 of the two are fixedly connected through screws.

[0141] The embodiment of the present invention also provides an integral air conditioner, specifically a window air conditioner 200, including: an outer box 290 and an electronic control box 100 according to any one of the above embodiments. The electronic control box 100 is arranged inside the outer box 290, and the top opening of the box body 11 of the electronic control box 100 faces the top wall of the outer box 290.

[0142] Since it includes the electronic control box 100 provided in any one of the above embodiments, the window air conditioner 200 of this embodiment has all the above beneficial effects and will not be elaborated here.

[0143] In a schematic embodiment, as Figure 11 and Figure 12 shown, the electronic control box 100 is horizontally placed inside the outer box 290, with the box cover 12 of the electronic control box 100 on top and the box body 11 below. Therefore, as long as the top and side parts of the electronic control box 100 are fully sealed, liquid can be prevented from entering the box body 1, thereby improving the safety of the electronic control box 100 and facilitating users to directly wash the window air conditioner 200 when there is a lot of dust inside the window air conditioner 200.

[0144] The following introduces a specific embodiment in conjunction with the drawings.

[0145] As Figure 11 、 Figure 12 and Figure 13 shown, this specific embodiment provides a window air conditioner 200, including: an electronic control box 100, an outer box 290, a compressor 230, an indoor side air duct assembly 270, an outdoor side air duct assembly 280, an indoor side fan 220, an outdoor side fan 210, an indoor side heat exchanger 250, an outdoor side heat exchanger 240, and a noise reduction assembly 260. The outer box 290 includes a box shell (not shown in the figure) and a chassis 292. The box shell includes side plates, and the side plates are provided with outdoor side air inlets. The chassis 292 is provided with a water receiving tray 2922, and the water receiving tray 2922 is located below the outdoor side heat exchanger 240.

The outdoor-side heat exchanger 240 is correspondingly arranged with the outdoor-side air duct.

[0156] As Figure 12 shown, the noise reduction assembly 260 is arranged between the indoor-side air duct assembly 270 and the outdoor-side air duct assembly 280. The noise reduction assembly 260 includes a sound insulation member 262 and a sound absorption member 264. The sound insulation member 262 divides the internal space of the outer box 290 into an indoor-side space and an outdoor-side space. The indoor-side air duct assembly 270, the indoor-side blower 220 and the indoor-side heat exchanger 250 are arranged in the indoor-side space. The outdoor-side air duct assembly 280, the outdoor-side blower 210 and the outdoor-side heat exchanger 240 are arranged in the outdoor-side space. The sound absorption member 264 is stacked with the sound insulation member 262.

[0159] As Figure 12 shown, the electric control box 100 includes two connecting lugs 13. One of the connecting lugs 13 is fixedly connected to the top of the sound insulation member 262 through a fastener, and the other connecting lug 13 is fixedly connected to the top of the outdoor-side air duct assembly 280 through a fastener. Thus, the connection between the indoor side and the outdoor side of the window air conditioner 200 is realized.

[0160] And, the side plate of the outer box 290 is provided with an outdoor-side air suction port. The air flow sucked in through the outdoor-side air suction port turns in the outer box 290 and then flows along the axial direction of the outdoor-side blower 210. The electric control box 100 is located on the air flow path of the outdoor-side blower 210, and the relative positions of the air inlet and the air outlet of the electric control box 100 are consistent with the air flow direction of the outdoor-side blower 210. In this way, as Figure 11 shown, a part of the air flow sucked in by the chassis 292 can enter the electric control box 100 through the air inlet to dissipate heat from the electric control box 100, and then be discharged from the air outlet of the electric control box 100, and then be blown by the outdoor-side blower 210 to the outdoor-side heat exchanger 240.

[0161] The compressor 230 is provided diagonally below the electric control box 100. The refrigerant pipe 41 of the window air conditioner 200 extends out of the outdoor heat exchanger 240 and then extends to form a subcooling pipe 294, as Figure 13 shown. The subcooling pipe 294 extends into the water receiving tray 2922, passes through the water receiving tray 2922, then extends upward and is connected to the refrigerant pipe 41 of the refrigerant radiator 4 of the electric control box 100. The refrigerant pipe 41 of the refrigerant radiator 4 extends out of the box body 1 of the electric control box 100 and then is connected to a throttling mechanism such as a capillary tube (not shown in the figure), and then enters the indoor heat exchanger 250. The refrigerant pipe 41 extending out of the indoor heat exchanger 250 is connected to the suction port of the compressor 230 to form a complete refrigerant cycle.

[0162] Taking the refrigeration operation as an example, the high-temperature and high-pressure refrigerant of the compressor 230 is discharged from the exhaust port of the compressor 230, enters the outdoor heat exchanger 240 to be condensed and cooled, then flows out, enters the subcooling pipe 294, exchanges heat with the condensed water in the water receiving tray 2922 to be further cooled, then enters the electric control box 100 to cool the electric control box 100, flows out of the electric control box 100, is further throttled and cooled by the throttling mechanism, then enters the indoor heat exchanger 250, evaporates and absorbs heat in the indoor heat exchanger 250, and then flows back to the compressor 230. Such a setting method is beneficial to improving the heat dissipation effect of the refrigerant radiator 4 and also beneficial to improving the refrigeration effect of the whole machine.

[0163] In summary, the electric control box and the window air conditioner provided by the embodiments of the present invention have good waterproofness, can prevent condensed water or rainwater from entering the electric control box, thereby improving the safety of the electric control box, and can also prevent flushing water from entering the electric control box, thereby facilitating the user to directly flush the window air conditioner or the integral air conditioner such as a mobile air conditioner, and improving the cleaning convenience of the window air conditioner or the integral air conditioner such as a mobile air conditioner.
