[0117] Optionally, the position of the enclosing plate 227 opposite to the recess 3012 is convex, so as to facilitate the connection between the enclosing plate 227 and the top cover 228, and also facilitate the connection of the enclosing plate 227 and the top cover 228 by the fixing member.

[0118] like Figure 5 and Figure 6, shows a schematic diagram of the outer box shell 221 and the cooperation between the outer box shell 221 and the electric control board. The outer box shell 221 surrounds the enclosure 227 and the top cover 228. The enclosure 227 is formed into a U-shaped structure and the open side is closed by the outdoor heat exchanger 222. The three sides of the enclosure 227 and the top cover 228 are provided with air inlets 203. The electric control box 3 is arranged adjacent to the side wall of the outer box shell 221 close to the inner box body 21, and a recess 3012 is arranged on the electric control box 3, and the position corresponding to the recess 3012 on the outer box shell 221 is convex.

[0119] The following describes the installation structure of the electric control box 3 in the embodiment of the present invention with reference to the accompanying drawings. In some embodiments of the present invention, the electric control box 3 can also be installed on the chassis 1. The electric control box 3 and the chassis 1 can be plugged in and positioned on the chassis 1 by the fixing parts. For example, after the electric control box 3 and the chassis 1 are plugged in, the electric control box 3 and the chassis 1 are pre-positioned, and then the electric control box 3 and the chassis 1 are fixedly connected together by the fixing parts.

[0120] According to the window air conditioner 1000 of the embodiment of the present invention, the electric control box 3 is positioned on the chassis 1 by a combination of plug-in and fixing parts, which can improve the stability of the electric control box 3, that is, the chassis 1 provides a stable support for the electric control box 3, and the plug-in and fixing parts are used to position the electric control box 3, so that the electric control box 3 can be quickly installed. Moreover, the plug-in can play a certain role in pre-positioning. The pre-positioning of the plug-in can realize the rapid positioning of the electric control box 3 and the chassis 1 through the fixing parts.

[0121] In combination with the above-mentioned embodiment, the electric control box 3 is arranged in the outer box shell 221, and the electric control box 3 is arranged on the inner side of the rear panel 227 or the outdoor air duct component 223 (that is, the side close to the inner box body 21).

[0122] In the present invention, one side of the bottom of the electric control box 3 is plugged with the chassis 1 through a latch 301, and the other side is connected to the chassis 1 by screws and other fixings. The bottom of the plastic inner shell of the electric control box 3 is provided with a latch 301 near the compressor 229, and the chassis 1 is provided with a socket 101 corresponding to the latch 301.

[0123] Alternatively, if Figures 7 to 10 The chassis 1 is provided with a socket 101, which can be set to be open in the horizontal direction (refer to the left and right direction in the figure), and a latch 301 is provided at one end of the bottom of the electric control box 3 in the horizontal direction, and the latch 301 is plugged into the socket 101 in the horizontal direction and is parallel to the chassis 1 in the horizontal direction. Through the cooperation between the socket 101 parallel to the chassis 1 and the latch 301, the latch 301 can be quickly plugged into the chassis 1, and the electric control box 3 and the chassis 1 can be conveniently connected through the fixing member.

[0124] Of course, the socket 101 of the present invention can also be set to be perpendicular to the chassis 1. In this case, the pin 301 on the electric control box 3 can be set to be hooked, that is, the plug-in positioning of the electric control box 3 and the chassis 1 is completed by inserting the pin 301 into the socket 101 and hooking the chassis 1. The present invention is mainly explained by taking the socket 101 along the horizontal direction as an example, but it is not a limitation of the protection scope of the present invention.

[0125] In addition, the electric control box 3 in the present invention can also be plugged in and matched with the chassis 1 by plugging in along the longitudinal direction (refer to the front-to-back direction in the drawings).

[0126] It should be noted that the horizontal direction in the present invention may be the left-right direction in the figure, the vertical direction may be the front-back direction in the figure, and the vertical direction may be the up-down direction in the figure.

[0127] Alternatively, if Figures 7 to 10 , a part of the chassis is raised to form a socket. Specifically, referring to the attached figure, a part of the chassis is raised upward to form a socket, and the edge of the top wall of the socket is extended obliquely to form a flared shape. Specifically, the edge of the top wall of the socket 101 is arranged to extend obliquely upward, so that the opening of the socket 101 is arranged to be flared. When the plug 301 is plugged into the socket 101, the plug 301 can be quickly matched with the socket 101, which facilitates the quick matching of the plug 301 and the socket 101, and improves the assembly efficiency.

[0128] Alternatively, if Figures 7 to 10 , a notch 102 is provided at the edge of the side wall of the socket 101. As shown in the figure, the front and rear side walls of the socket 101 are provided with notches 102. In this way, the opening of the socket 101 will form a larger flared shape, which further facilitates the matching of the plug 301 and the socket 101, so that the plug 301 can be quickly plugged into the socket 101, and the plug 301 and the socket 101 are quickly positioned.

[0129] Alternatively, if Figures 7 to 10, a clearance notch 309 is provided at the position where the electric control box 3 is opposite to the socket 101. The clearance notch 309 can provide a clearance structure, for example, to make way for the socket 101, to make way for the wiring structure, etc., and can also provide a larger installation space for convenient observation. The clearance notch 309 has a first surface and a second surface. The first surface is opposite to the socket 101 in a direction perpendicular to the chassis 1 (i.e., vertically, or in other words, in the up-down direction in the figure), and the second surface is opposite to the socket 101 in a horizontal direction. A connecting portion 3043 is provided at the clearance notch 309. The connecting portion 3043 is connected to the first surface and the second surface respectively, and the bolt 301 is connected to the connecting portion 3043. That is, the bolt 301 structure is arranged at the clearance notch 309, which can facilitate the rapid matching of the bolt 301 and the socket 101, and through the connection of the connecting portion 3043, the structural strength of the clearance notch 309 can be improved. Moreover, the overall structure of the electric control box 3 is simplified.

[0130] Alternatively, if Figures 7 to 10 The connecting portion 3043 includes a first connecting rod 3044. The first connecting rod 3044 is connected to the first surface and extends toward the socket 101 (refer to downward in the figure), and the plug 301 is connected to the free end of the first connecting rod 3044. This facilitates the plugging and matching of the plug 301 and the socket 101. In addition, by providing the clearance notch 309, a larger visual space can be provided, which facilitates the plugging operation.

[0131] In addition, if Figures 7 to 10 The connecting portion 3043 also includes a second connecting rod 3045, which is connected to the second surface, and the second connecting rod 3045 extends toward the socket 101 and is connected to the first connecting rod 3044. The connection between the second connecting rod 3045 and the first connecting rod 3044 can effectively improve the structural strength of the first connecting rod 3044, that is, effectively improve the structural strength of the pin 301, and improve the positioning stability of the pin 301 and the chassis 1.

[0132] In addition, if Figures 7 to 10 The connection part 3043 further includes a reinforcing rib 3046, and the reinforcing rib 3046 is connected between the first surface, the second surface, the first connecting rod 3044 and the second connecting rod 3045. The reinforcing rib 3046 can effectively improve the structural strength of the connection part 3043 and the electric control box 3, and also improve the structural strength of the latch 301.

[0133] In addition, the reinforcing rib 3046 in the present invention is a ring-shaped hollow structure, a U-shaped structure, a T-shaped structure, etc. Through the structure of the reinforcing rib 3046, an air flow channel can be formed on the connecting portion 3043, so that air flow can pass through to enhance the heat dissipation of the electric control box 3.

[0134] In addition, a wire outlet 3013 can be provided at the gap 309, and a wire harness can be led out from the wire outlet 3013. The shape of the reinforcing rib 3046 can facilitate the routing of the wires. For example, the reinforcing rib 3046 is provided in a U-shape extending along the first connecting rod 3044, the second connecting rod 3045 and the second surface.

[0135] Alternatively, if Figures 1 to 10 , the chassis 1 is provided with a first convex bump 11, and the socket 101 is provided on the top wall of the first convex bump 11. In this way, after the plug 301 is inserted into the socket 101, there will be a certain space between the plug 301 and the bottom surface of the chassis 1, and the plug 301 will not protrude from the bottom surface of the chassis 1, thereby ensuring that the chassis 1 can be stably supported on other equipment or structures. In addition, by providing the first convex bump 11, water can be prevented from entering the electric control box 3 under the action of siphoning.

[0136] Alternatively, if Figures 7 to 10 The other end of the bottom of the electric control box 3 in the transverse direction is provided with a mounting portion 302, and the mounting portion 302 is connected to the chassis 1 through a fixing member, and is transversely parallel to the chassis 1. It is convenient for the fixing member to connect the mounting portion 302 and the chassis 1.

[0137] Alternatively, if Figures 7 to 10 The electric control box 3 has mounting parts 302 extending longitudinally from both sides thereof that are opposite to each other in the longitudinal direction. That is, the mounting parts 302 are led out from the front and rear sides of the electric control box 3, so that the mounting parts 302 and the chassis 1 can be conveniently connected through the fixing parts, and the connection efficiency between the electric control box 3 and the chassis 1 can be effectively improved.

[0138] In addition, the plurality of fixing members on the mounting portions 302 on both sides of the electric control box 3 are arranged in a triangular shape. The fixing members arranged in a triangular shape can form a stable positioning structure 3019, which facilitates the stable connection between the electric control box 3 and the chassis 1.

[0139] Of course, the triangular arrangement of the fixing parts in the present invention is only one embodiment of the present invention. The fixing parts connecting the electric control box 3 and the chassis 1 in the present invention can also be arranged in a quadrilateral or other polygonal shape, or even only one or two fixing parts are set. Due to the coordination of the plug-in and the fixing parts, the electric control box 3 and the chassis 1 can also be quickly positioned.

[0140] Alternatively, if Figures 7 to 10 The chassis 1 is provided with a second convex bump 12, and the mounting portion 302 is connected to the second convex bump 12. The second convex bump 12 can support the electric control box 3 to prevent condensed water on the chassis 1 from entering the inside of the electric control box 3, and can also facilitate the installation of the electric control box 3, avoid the formation of a convex structure on the bottom surface of the chassis 1 by the fixing part, effectively improve the stability of the cooperation between the electric control box 3 and the chassis 1, and facilitate the installation of the chassis 1 on other equipment or structures.

[0141] Optionally, a groove (not shown in the figure) is provided on the second convex bump 12, which is opposite to the electric control box 3 and recessed away from the electric control box 3. The matching area between the electric control box 3 and the chassis 1 can be reduced, thereby facilitating stable matching between the electric control box 3 and the chassis 1, and facilitating airflow passing between the electric control box 3 and the chassis 1, avoiding heat accumulation and facilitating heat dissipation.

[0142] Optionally, in the present invention, the aforementioned first bulge 11 is higher than the second bulge 12, that is, the plug-in structure of the electric control box 3 and the connecting structure of the fixing part are located on different planes, thereby making it more convenient to position the electric control box 3 on the chassis 1 and improving the positioning efficiency and effect of the electric control box 3.

[0143] Alternatively, if Figure 8 The box assembly 2 includes a compressor 229, which is used to provide power for the flow of heat exchange refrigerant. The electric control box 3 is arranged adjacent to the compressor 229, that is, the electric control box 3 is arranged in the part of the outer box 22. The end of the bottom of the electric control box 3 adjacent to the compressor 229 is plugged into the chassis 1, and the end of the bottom of the electric control box 3 away from the compressor 229 is positioned with the chassis 1 by a fixing. Due to the arrangement of the compressor 229, the installation space of the end of the electric control box 3 adjacent to the compressor 229 is relatively small, which is not suitable for connecting the electric control box 3 and the chassis 1 through a fixing, and the plug-in structure has relatively small requirements for the installation space. Therefore, the electric control box 3 is arranged to be plugged in at the end close to the compressor 229 and connected to the fixing at the end away from the compressor 229, which can improve the matching efficiency between the electric control box 3 and the chassis 1 and facilitate the installation of the electric control box 3 on the chassis 1.

[0174] In addition, in order to improve the sealing performance of the sealing structure, in the present invention, a fixing piece is provided at a position adjacent to the sealing ring 3016, so that the sealing rib 3041 can be pressed more tightly against the sealing ring 3016 through the connection of the fixing piece, or the sealing rib 3041 can be effectively matched with the sealing groove 3015, thereby improving the sealing performance between the first inner shell 311 and the second inner shell 312 of the box. Specifically, Fig.16 , at a position adjacent to the sealing ring 3016, the first inner shell 311 and the second inner shell 312 are connected by a fixing member.

[0175] Alternatively, if Fig.16 and Fig.18The inner side of the peripheral wall of the second inner shell 312 is provided with a first slot 3042 opening toward the first inner shell 311, the peripheral wall of the first inner shell 311 is embedded in the first slot 3042, and the sealing rib 3041 is provided on the inner bottom surface of the first slot 3042. By the peripheral wall of the first inner shell 311 cooperating with the first slot 3042, and the sealing rib 3041 cooperating with the sealing groove 3015, a circuitous joint surface can be formed at the joint of the first inner shell 311 and the second inner shell 312, so that water and the like can be effectively prevented from entering the interior of the electric control box 3.

[0176] Optionally, the peripheral wall edge of the second inner shell 312 is provided with a convex rib 3047 protruding in a direction away from the first inner shell 311. Since the peripheral wall of the first inner shell 311 is embedded in the first slot 3042, and the convex rib 3047 is provided on the outer peripheral surface of the second inner shell 312, when there is water or other medium entering the outer peripheral surface of the second inner shell 312, the convex rib 3047 can prevent the water or other medium from entering the joint between the first inner shell 311 and the second inner shell 312, thereby further effectively improving the waterproof performance between the first inner shell 311 and the second inner shell 312.

[0177] The first inner shell 311 cooperates with the second inner shell 312. In order to prevent external water from entering the electric control, a double-groove and double-rib cross-cooperation design is adopted, and a rubber sealing strip is used in the middle for secondary sealing; wherein, the first card slot 3042 is arranged on the second inner shell 312, and is designed to cooperate with the outer edge rib of the first inner shell 311. The outer edge is designed to be drafted outward, which is conducive to outward drainage. The sealing groove 3015 is designed on the first inner shell 311 and cooperates with the convex. The sealing strip is designed in the sealing groove 3015, and cooperates with the rubber sealing strip through the convex rib 3047 to achieve a secondary sealing effect to prevent external water from entering the electric control box 3.

[0178] Optionally, the ribs 3047 protrude from the inner circumference or outer circumference of the second outer shell 314. In this way, when there is water or other medium on the second outer shell 314, the ribs 3047 can also effectively block and prevent the water or other medium from flowing to the joint between the first inner shell 311 and the second inner shell 312.

[0179] Optionally, a second slot 3017 with an opening facing away from the second inner shell 312 is provided on the peripheral wall of the first inner shell 311, and the edge of the second outer shell 314 extends into the second slot 3017. In this way, the assembly efficiency and the fireproof and waterproof performance can be improved.

[0180] For example, Fig.16 and Fig.18 The top wall of the first inner shell 311 is provided with an I-shaped structure with a sealing groove 3015 and a second clamping groove 3017 respectively provided on both sides along the longitudinal direction.

[0181] Alternatively, if Fig.16 and Fig.18 A recessed structure is provided on the outer surface of one end of the electric control box along the vertical direction, and the other end of the electric control box along the vertical direction is a raised structure raised relative to the recessed structure, and a patching block is provided at the step formed between the recessed structure and the raised structure. In other words, a recessed structure 307 is provided on the outer surface of the electric control box 3, the electric control box 3 is arranged along the vertical direction, the recessed structure 307 is arranged at one end of the electric control box 3 along the vertical direction, and the other end of the electric control box 3 along the vertical direction is a raised structure raised relative to the recessed structure 307, and a patching block 32 is provided at the step formed between the recessed structure 307 and the raised structure.

[0182] Specifically, a recessed structure 307 is provided on the outer surface of one vertical end of the electric control box 3, and relatively speaking, a convex structure will exist on the other vertical end of the electric control box 3, that is, a recessed structure 307 is formed on one vertical end of the outer surface of the box body 31 and a convex structure is formed on the other end.

[0183] Among them, Fig.16 and Fig.18 The convex structure and the concave structure 307 are relative to each other, that is, the concave structure 307 is concave relative to the convex structure, and the convex structure is convex relative to the concave structure 307.

[0184] At this time, there will be a gap at the junction of the recessed structure 307 and the raised structure (i.e., the step), and the gap here can be closed by stretching the sheet metal through sheet metal forming, or it can be sealed by other methods, for example, by setting a patch block 32 to close the gap here.

[0185] It should be noted that the box body 31 in the present invention includes an insulating inner shell 303 and a fireproof outer shell 304. The fireproof outer shell 304 is generally formed by sheet metal. Taking the sheet metal formed into a rectangular parallelepiped structure as an example, a part of one side of the rectangular parallelepiped is sunken to form a sunken structure 307. The sunken structure 307 here will have a gap with the non-sunk part, so that the junction of the sunken structure 307 and the non-sunk part will form an opening, which can be closed by sheet metal processing. However, the cost of this sheet metal processing is relatively high. Therefore, a patch block 32 is provided in the present invention to close the opening. In addition, the patch block 32 is to close the opening on the fireproof outer shell 304, while the insulating inner shell 303 can be injection molded without forming an opening. Therefore, after the patch block is provided, the relative integrity of the fireproof outer shell 304 can be guaranteed, thereby improving the fireproof performance of the electric control box 3.

[0186] In addition, the electric control box 3 in the present invention can be arranged vertically, and the upper part of the box body 31 is provided with the concave structure 307 and the lower part is provided with a convex structure. When the electric control box 3 is placed outdoors, sunlight may irradiate the electric control box 3, especially the position where the patch block 32 on the electric control box 3 is located. When the patch block 32 is not provided, the sunlight irradiation may damage the electric control box 3 (insulating inner shell 303). Therefore, the patch block 32 can effectively protect the electric control box 3 and improve the stability of the operation of the electric control box 3.

[0187] Specifically, since the box body 31 includes an insulating inner shell 303 and a fireproof outer shell 304, and since the opening caused by the aforementioned drop is formed on the fireproof outer shell 304, a portion of the insulating inner shell 303 is exposed. The insulating inner shell 303 is generally made of plastic, and the exposed portion is easily damaged by sunlight. Therefore, the present invention can prevent sunlight from directly irradiating the plastic part by providing a sealing block, thereby effectively protecting the box body 31. In addition, in combination with Fig.16 and Fig.18 The end of the protruding structure facing the concave structure 307 is covered by the patch block 32. The patch block 32 can maintain the integrity of the electric control box 3, effectively protect the internal space of the box body 31, and maintain the stable operation of the electric control box 3. In addition, the patch block 32 also plays a role in fire prevention.

[0188] Optionally, a reinforcement structure (for example, a reinforcement structure formed by stamping) is provided at the recessed structure 307 and its vicinity, and the reinforcement structure may bridge over the recessed structure 307, the convex structure, and the area near the recessed structure 307 and the convex structure.

[0189] Alternatively, if Fig.13 and Fig.18 The patch block 32 includes: a cover plate 321, the cover plate 321 covers the step between the convex structure and the concave structure 307, a first flange 322 extending vertically toward the concave structure 307 is provided on a portion of the periphery of the cover plate 321, the first flange 322 is connected to the wall of the concave structure 307, and a second flange 323 extending vertically toward the convex structure is provided on another portion of the periphery of the cover plate 321, the second flange 323 is connected to the wall of the convex structure. Through the first flange 322 and the second flange 323, the patch block 32 can be stably connected to the box body 31.

[0190] Specifically, a portion of the edge of the cover plate 321 is provided with a first flange 322 extending upward, the first flange 322 is connected to the wall of the recessed structure 307, and a portion of the edge of the cover plate 321 extends downward to form a second flange 323, and the second flange 323 is connected to the wall of the raised structure.

[0191] Alternatively, if Figures 13 to 18A portion of the wall of the recessed structure 307 protrudes outward from the electric control box 3 and forms a vertical insertion hole 3068. A plug buckle 324 extending vertically toward the cover plate 321 is formed on the first flange 322, and the plug buckle 324 is vertically plugged into the insertion hole 3068. In addition, as optionally Figures 13 to 18 A locking protrusion 3069 is provided on the outer peripheral surface of the protruding structure, and a locking hole 325 is formed on the second flange 323 , and the locking protrusion 3069 is locked into the locking hole 325 .

[0192] During use, the patch block 32 will be installed from top to bottom. At this time, the socket 101 on the first flange 322 will be plugged into the socket 3068, and the clamping hole 325 on the second flange 323 will cooperate with the clamping hole 325, thereby completing the positioning of the patch block 32.

[0193] The patch block 32 can be installed by the above-mentioned snap-fit ​​structure, but the assembly method of the snap-fit ​​structure is easily dislocated by external force. Therefore, the present invention further provides a fixing member to connect the patch block 32 and the box body 31, so that after the patch block 32 is pre-positioned by snapping and plugging, the patch block 32 and the box body 31 are fastened by the fixing member.

[0194] Among them, Figures 13 to 18 The first flange 322 can be connected to the wall screw of the recessed structure 307; the second flange 323 can also be connected to the wall screw of the raised structure.

[0195] In addition, if Figures 13 to 18 The first flange 322 , the second outer shell 314 , the second inner shell 312 , and the first inner shell 311 are connected in series through the same fixing member, thereby simplifying the assembly structure and improving the integrity and stability of the overall structure of the electric control box 3 .

[0196] Optionally, the cover plate 321 is square, two adjacent sides of the cover plate 321 are provided with first flanges 322 , and the other two adjacent sides of the cover plate 321 are provided with second flanges 323 .

[0197] As mentioned above, Figures 13 to 18 The box body 31 is generally constructed in a rectangular parallelepiped shape, and a portion of one side of the box body 31 is recessed to form a square recessed structure 307. In this way, a substantially square opening is formed between the recessed structure 307 and the non-recessed portion of the box body 31, and the opening can be closed by a square cover plate 321. The recessed structure 307 formed at the side of the box body 31 will have two adjacent surfaces, which are connected to the two adjacent surfaces by two first flanges 322; and the non-recessed portion of the side of the box body 31 will also form two adjacent surfaces that are substantially at right angles, which are connected to the two adjacent surfaces by two second flanges 323.

[0198] The aforementioned recessed structure 307 is arranged on the box cover 306 (a combination of the second inner shell 312 and the second outer shell 314), the patch block 32 and the box cover 306 adopt a plug-in + snap-on connection structure, and 6 "E"-shaped reinforcing ribs 304 are designed at the recessed part of the electric control box 3, and the second outer shell 314 is assembled with a snap-on design.

[0199] In addition, the electric control box in the present invention can be arranged in a vertical direction, wherein the vertical direction is a direction perpendicular to the chassis. The horizontal and vertical directions in the present invention are parallel to the chassis, and the horizontal, vertical and vertical directions are perpendicular to each other.

[0200] In addition, in combination with other embodiments of the present invention, a radiator 35 is provided in the box body 31 of the electric control box 3. The radiator 35 can extend out of the box body 31. The portion of the radiator 35 extending out of the box body 31 can be located at the recessed structure 307, thereby improving the space utilization of the electric control box 3.

[0201] In addition, in some embodiments of the present invention, a reactance 34 is disposed in the box body 31 of the electric control box 3, and at least a portion of the reactance 34 is disposed in the protruding structure, so that the internal space of the box body 31 is effectively utilized and the space utilization rate is improved.

[0202] like Figures 1 to 34 In some embodiments of the electric control box 3 of the present invention, the electric control box 3 includes: a box body 31 and a circuit board 33. The circuit board 33 is arranged in the box body 31, and the circuit board 33 has electronic components 331. By integrating the circuit board 33 into the box body 31, the circuit board 33 is effectively protected, and the production and modular design of the circuit board 33 are facilitated.

[0203] The electric control box 3 in this embodiment can adopt the structure of the electric control box 3 in other embodiments, and the structure of the electric control box 3 in this embodiment can also be applied to other embodiments. For example, the box body 31 of the present invention can adopt the structure of the box body 31 in the aforementioned electric control box 3. In addition, when the electric control box 3 is applied to the window air conditioner 1000, the installation method of the electric control box 3 in the aforementioned window air conditioner 1000 can also be adopted.

[0204] In combination with the above-mentioned embodiment, the circuit board 33 is installed in the insulating inner shell 303. In addition, optionally, the reactor 34 is installed on the fireproof outer shell 304.

[0205] Further, in combination with the above-mentioned embodiment, the circuit board 33 is mounted on the first inner shell 311, and the inner side of the first inner shell 311 is provided with a positioning structure 3019 arranged in a direction surrounding the circuit board 33, and the positioning structure 3019 includes a positioning rib 3020 and a positioning hook 3021. The positioning structure 3019 can effectively position the circuit board 33. Fig. 20In the direction around the circuit board 33, positioning ribs 3020 are provided. The circuit board 33 placement area is formed around the circuit board 33 by the positioning ribs 3020, and the circuit board 33 is placed in the space formed by the positioning ribs 3020. In addition, the positioning of the circuit board 33 is achieved by the positioning hooks 3021. Moreover, positioning ribs 3020 are further provided between the circuit board 33 and the inner surface of the electric control box 3. The circuit board 33 can be separated from the inner surface of the electric control box 3 by the positioning ribs 3020, so as to facilitate the heat dissipation and waterproofing of the circuit board 33.

[0206] Optionally, the positioning ribs 3020 and the positioning hooks 3021 can be arranged at staggered intervals around the circuit board 33. In this way, while ensuring the stable installation of the circuit board 33, the circuit board 33 is separated from the inner wall surface of the electric control box 3 to facilitate airflow and form a better heat dissipation effect.

[0207] Optionally, the positioning ribs 3020 surround a placement space on the first inner shell 311 , the circuit board 33 is disposed in the placement space, and the positioning hooks 3021 include a plurality of positioning hooks 3021 that are arranged at intervals around the circuit board 33 .

[0208] Optionally, a guide rib 3022 is provided on the peripheral wall of the placement space, the guide rib 3022 is perpendicular to the circuit board 33 and respectively connects the inner side surface and the inner bottom surface of the placement space, and the end of the guide rib 3022 away from the inner bottom surface of the placement space is configured as a wedge-shaped structure whose height relative to the inner side surface of the placement space gradually increases in the direction toward the inner bottom surface of the placement space. The wedge-shaped structure can achieve guidance of the circuit board 33 during installation.

[0209] For example, a guide rib 3022 is set on one side of the placement space, and a positioning hook 3021 is set on the other side opposite to the guide rib 3022. One side of the circuit board 33 is inserted into the placement space and positioned by the positioning hook 3021, and then the circuit board 33 is pressed down. Through the action of the guide rib 3022, the circuit board 33 can be smoothly installed in the placement space.

[0210] Optionally, a positioning notch 102 is provided at the edge of the circuit board 33, and a positioning protrusion 3072 is provided in the box body 31, and the positioning protrusion 3072 cooperates with the positioning notch 102 to position the circuit board 33. Through the cooperation between the positioning notch 102 and the positioning protrusion 3072, foolproof installation of the circuit board 33 can be achieved, and the circuit board 33 can be installed in a predetermined orientation to avoid installation errors and improve assembly efficiency.

[0211] Optionally, the circuit board 33 is separated from the inner surface of the box body 31. The gap between the circuit board 33 and the box body 31 can be used for airflow to pass through and take away the heat on the circuit board 33, thereby improving the heat dissipation of the circuit board 33 and avoiding the influence of possible condensed water.

[0212] Optionally, a wiring groove 3027 is provided in the electric control box 3 around the circuit board 33, and a wire slidable rib 3031 is provided in the wiring groove 3027 for separating the wire harness, and wire fixing ribs 3033 are arranged at intervals along the extension direction of the wiring groove 3027 on the electric control box 3 to position the wire harness.

[0214] like Fig.21 and Fig. 22 The electric control box 3 further includes a reactance 34 , which is disposed in the box body 31 , and the circuit board 33 and the reactance 34 are spaced apart from each other, thereby further improving the integration of the electric control box 3 .

[0215] According to the electric control box 3 of the embodiment of the present invention, the circuit board 33 and the reactor 34 are integrated into the electric control box 3, which can facilitate the production and modular design of the electric control box 3 and the design, production and installation of the electric control structure.

[0216] In addition, when the electric control box 3 is applied to the window air conditioner 1000, the aforementioned electric control box 3 is applied to ensure the stable operation of the window air conditioner 1000, improve the stability of the window air conditioner 1000, and improve the integration rate of the electric control box 3, which facilitates the modular design, production, installation and maintenance of the window air conditioner 1000.

[0217] Alternatively, if Fig.24 A partition wall 3018 is provided in the box body 31, and the partition wall 3018 separates the circuit board 33 and the reactance 34, and a wire opening 3037 is provided on the partition wall 3018 to connect the chambers where the circuit board 33 and the reactance 34 are located.

[0218] Reactor 34 can be connected to circuit board 33. By dividing by partition wall 3018, circuit board 33 and reactance 34 can each perform their respective functions to avoid mutual interference, and partition wall 3018 can also play a certain heat insulation role to avoid the heat between circuit board 33 and reactance 34 affecting each other. The wire port 3037 on partition wall 3018 can be used for wire harness to pass through to connect circuit board 33 and reactance 34.

[0219] The partition wall 3018 on the box body 31 may be a ring-shaped structure, and the reactance 34 is disposed inside the ring-shaped partition wall 3018 .

[0220] Optionally, one end of the reactance 34 is plugged into the box body 31 , and the other end of the reactance 34 is connected to the box body 31 via a fixing member, which can facilitate the stable connection between the reactance 34 and the box body 31 and improve the stability of the reactance 34 .

[0221] Optionally, the reactance 34 is disposed in the box body 31 , and at least one of a grounding connector and a grounding mark is disposed on the outside of the box body 31 at a position opposite to the reactance 34 .

[0222] Optionally, the multiple screws on the surface of the electrical control box 3 corresponding to the position of the reactance 34 are two for grounding and two for connecting the reactance 34, and the multiple screws are located in the inner recess (i.e., the recess formed by the sink structure 3066 on the outer surface of the box body 31) to prevent the screw heads from being exposed.

[0223] Optionally, in combination with the aforementioned embodiment, the reactance 34 may be configured to be directly mounted on the first housing 313 .

[0224] Alternatively, if Fig.31 The first inner shell 311 is provided with a relief opening 3038, and the reactance 34 is provided at the relief opening 3038 and directly mounted on the first outer shell 313. The relief opening 3038 may be formed by being surrounded by the aforementioned partition wall 3018.

[0225] Optionally, combined Figures 1 to 18 , a part of the first shell 313 is sunken to form a sinking structure 3066 inside the first shell 313, and the reactor 34 is installed on the sinking structure 3066. In this way, more installation space will be provided for the reactor 34, and the reactor 34 can be connected to the sinking structure 3066 through a fixing member. Since the sinking structure 3066 forms a depression on the outer surface of the box body 31, when the reactor 34 and the sinking platform are connected by the fixing member, the fixing member will extend into the depression formed by the sinking structure 3066, effectively protecting the smooth appearance of the electric control box 3, preventing the fixing member from extending out of the outer surface of the electric control box 3, preventing the screw head of the fixing reactor 34 and the grounding screw head from protruding out of the outer surface of the electric control box 3, and preventing injuries during assembly or transportation of components.

[0226] In addition, the sink structure 3066 can also be provided to strengthen the structure.

[0227] In addition, a grounding structure can be provided in the depression formed by the sink structure 3066, and grounding can be achieved through the grounding structure, thereby further improving the safety of the operation of the electric control box 3. The reactor 34 is installed on the sink structure 3066 at the bottom of the box body 31, which, on the one hand, strengthens the structural strength of the sheet metal bottom plate 351, and on the other hand, prevents the screw heads of the reactor 34 and the grounding screw heads from protruding from the electric control bottom plate 351, thereby avoiding injury during assembly.

[0228] Optionally, a grounding structure is provided on at least one of the first housing 313 and the second housing 314 .

[0229] Optionally, combined Figures 12 to 15 The box body 31 is provided with a clearance opening 3058 , and the radiator 35 extends out of the box body 31 from the clearance opening 3058 .

[0230] In combination with the above-mentioned embodiment, a recessed structure 307 is provided on the outer surface of the box body 31 , and the yielding opening 3058 can be provided on the yielding structure.

[0231] In addition, at least a portion of the reactance 34 in the present invention may be disposed in a convex structure corresponding to the concave structure 307 .

[0232] like Figures 16 to 26 The reactance 34 and the circuit board 33 are arranged up and down. The reactance 34 can be arranged below the circuit board 33 to lower the center of the electric control box 3 and improve stability. In addition, Figures 16 to 26 The reactance 34 and the box body 31 are positioned by means of a buckle 324 and a fixing piece, so that the reactance 34 is stably fixed on the box body 31. The reactance 34 is provided with a grounding screw and a grounding mark, wherein the grounding screw passes through the box body 31 from the inside of the box body 31. Specifically, since the reactance 34 is heavy, in order to ensure the stability of the center of gravity of the electric control box 3, the reactance 34 is fixed below the first shell 313 and installed on the first shell 313, which is conducive to heat dissipation on the one hand, and the structure is firm and reliable on the other hand.

[0233] Optionally, the circuit board 33 is fixedly installed in the insulating inner shell 303, and the reactance 34 is installed on the fireproof outer shell 304. In this way, effective insulation of the circuit board 33 can be ensured, thereby improving the safety of the operation of the circuit board 33, and the reactance 34 is installed in the fireproof outer shell 304, which can improve the stability of the reactance 34.

[0234] This is because, generally, the mass of the reactance 34 is relatively large, and by directly installing the reactance 34 on the fireproof housing 304, the stability of the reactance 34 can be effectively improved.

[0235] like Figures 16 to 26 The electric control box 3 also includes a radiator 35, which is connected to at least part of the electronic components 331 on the circuit board 33 and is suitable for heat transfer to form a heat dissipation structure. The circuit board 33 can be cooled by the radiator 35, especially the electronic components 331 on the circuit board 33 with high heat generation, which can quickly dissipate the heat and avoid malfunction caused by overheating of the circuit board 33.

[0236] In combination with the above-mentioned embodiment, optionally, a clearance opening 3058 is provided on the wall of the box body 31, and the clearance opening 3058 can be used to allow the radiator 35 to extend out of the box body 31. This facilitates the heat dissipation of the radiator 35, improves the heat dissipation effect, effectively maintains the operating environment of the circuit board 33, and improves the working stability of the circuit board 33.

[0237] Alternatively, if Figures 16 to 26The heat sink 35 includes: a bottom plate 351 and heat dissipation fins 352. The bottom plate 351 is connected to at least part of the electronic components 331 on the circuit board 33 and is suitable for heat transfer. The bottom plate 351 is located in the box body 31. The heat dissipation fins 352 are connected to the bottom plate 351 and extend out of the box body 31 from the clearance opening 3058. Part of the heat generated during the operation of the circuit board 33 will be transferred to the bottom plate 351, and then the heat on the bottom plate 351 will be transferred to the heat dissipation fins 352. The heat dissipation fins 352 complete the heat dissipation of the corresponding electronic components 331 on the circuit board 33 by exchanging heat with the medium outside the electric control box 3.

[0238] In the present invention, the chassis 1 and the heat dissipation fins 352 of the heat sink 35 can be formed in one piece, thereby effectively improving the heat conduction and heat dissipation efficiency.

[0239] In addition, if Figures 16 to 26 The heat sink 35 may further include a sealing member 353, the sealing member 353 surrounds the heat dissipation fins 352, and the sealing member 353 is disposed between the bottom plate 351 and the periphery of the clearance opening 3058 to form a sealing structure. Through the sealing effect of the sealing member 353, water outside the electric control box 3 can be prevented from entering the electric control box 3 to cause safety hazards.

[0240] Alternatively, if Figures 16 to 26 The surface of the sealing member 353 that abuts against the periphery of the clearance opening 3058 is provided with a plurality of annular ribs 354, which are in the form of annular rings extending along the periphery of the sealing member 353, and the plurality of annular ribs 354 are configured as a plurality of rings arranged at intervals from the inside to the outside. In this way, the plurality of annular ribs 354 will form a multi-layer sealing structure with the periphery of the clearance opening 3058, further improving the sealing effect.

The heat conducting sheet 358 is designed to be installed on the circuit board 33, and the heat of the heating device on the circuit board 33 is transferred to the heat conducting sheet 358 through the heat conducting pins, and then the heat is transferred to the heat sink 35 through the heat dissipation paste (heat conducting medium) between the heat conducting sheet 358 and the heat sink 35, and finally the heat sink 35 transfers the excess heat to the outside of the electric control box 3.

[0250] In combination with the above-mentioned embodiment, a circuit board 33 is provided in the electric control box 3, and electronic components 331 are provided on the circuit board 33. Some of the electronic components 331 generate a large amount of heat and need to be radiated by a radiator 35. The radiator 35 and the electronic components 331 are used to dissipate heat.

In addition, it can be seen from the accompanying drawings that the radiator 35 extends out of the electric control box 3.

[0251] In addition, if Figures 16 to 26 The upper depression on the right side of the second housing 314 forms a structure for accommodating the protruding portion of the radiator 35. The second housing 314 is provided with a reinforcing rib 3046, which is arranged across the depression and other parts of the second housing 314. In addition, after the recessed structure 307 is provided on the second housing 314, an opening is formed at the lower end of the recessed structure 307, and the opening cannot be closed by sheet metal forming. A patch block 32 can be provided to cover. The patch block 32 can maintain the integrity of the electric control box 3, effectively protect the internal space of the box body 31, and maintain the stable operation of the electric control box 3.

[0252] Optionally, the bottom plate 351 and the seal 353 of the radiator 35 are compressed by the second inner shell 312 , and fixing members are respectively provided on both sides of the radiator 35 in the longitudinal direction, which lock the first inner shell 311 and the second inner shell 312 to compress the seal 353 .

[0253] In combination with the aforementioned embodiment, the circuit board 33 is installed on the inner side of the box seat 305, and the heat sink 35 is installed on the circuit board 33. When the box cover 306 is closed on the box seat 305, the heat sink 35 extends out from the box cover 306. At this time, fixing parts can be provided on the box cover 306 at positions on both sides of the upper side of the heat sink 35 to connect and position the box cover 306 and the box seat 305. In this way, the connection between the box cover 306 and the box seat 305 can be facilitated, and the sealing part 353 between the heat sink 35 and the box cover 306 can be clamped, thereby improving the sealing between the heat sink 35 and the box cover 306.

[0254] In combination with other embodiments of the present invention, the circuit board 33 and the heat sink 35 are installed on the box seat 305, the box cover 306 is provided with a clearance opening 3058, the heat sink 35 extends out from the clearance opening 3058, and a sealing member 353 is provided between the heat sink 35 and the inner surface of the box cover 306. The first inner shell 311 and the second inner shell 312 are connected by fixing members on both sides of the heat sink 35 in the vertical direction. One of the fixing members connects and fixes the second outer shell 314, the second inner shell 312, and the first inner shell 311 together in series, and the other fixing member connects the patch block 32 (the first flange 322), the second outer shell 314, the second inner shell 312, and the first inner shell 311 together.

[0255] Alternatively, if Fig. 27 At least one of the first inner shell 311 and the second inner shell 312 is provided with a heat dissipation window 3023. Through the heat dissipation window 3023, the heat inside the electric control box 3 can be conveniently exchanged with the heat outside the electric control box 3. Specifically, during use, the heat inside the electric control box 3 will be discharged to the fireproof outer shell 304 through the heat dissipation window 3023. The fireproof outer shell 304 is generally supported by metal materials. In this way, after the heat is transferred to the fireproof outer shell 304, it will be easy to exchange heat with the external medium of the box body 31, thereby improving the heat dissipation effect of the electric control box 3.

[0256] In addition, since only the heat dissipation window 3023 is provided on the inner shell, and the heat dissipation window 3023 is closed by the outer shell, while improving the heat dissipation effect, it can also prevent external water, steam, etc. from entering the electric control box 3, thereby ensuring the stable operation of the electric control box 3.

[0257] Alternatively, if Fig. 27 The heat dissipation window 3023 is connected with support ribs 3024, and the support ribs 3024 are in the form of a grid arranged in a crisscross pattern. By providing the support ribs 3024, the structural strength and stability of the inner shell can be effectively improved.

[0258] Optionally, the circuit board 33 is mounted on the first inner shell 311 , and a heat dissipation window 3023 is provided in an area of ​​the first inner shell 311 opposite to the circuit board 33 to improve the heat dissipation effect of the circuit board 33 .

[0259] Optionally, there is a gap of 8 mm to 18 mm between the circuit board 33 and the first shell 313 , and a safe distance is maintained between the circuit board 33 and the first shell 313 , which can effectively improve the safety of the electric control box 3 .

[0260] The circuit board 33 will generate heat during the operation of the whole machine, especially the heat generated by some heating components will cause the temperature in the electric control box 3 to rise too high, thereby damaging other electrical components. Therefore, in order to solve the heat dissipation problem of the electric control box 3, the back of the electric control board is hollowed out, so that the heat in the airtight position directly contacts the outer sheet metal (first shell 313), and the heat inside the electric control box 3 is dissipated to the outside of the electric control box 3. In order to ensure an effective safety distance between the sheet metal and the electrical components, the distance D between the circuit board 33 and the second shell 314 is 8-18 mm, which is conducive to heat dissipation and is also for safety considerations.

[0261] In combination with the above-mentioned embodiment, in the electric control box 3, the inductor 34 and the circuit board 33 are both arranged in the electric control box 3, and the inner surface of the plastic inner cover of the electric control box 3 has a partition wall 3018, which separates the circuit board 33 area and the inductor 34 area). In addition, a heat sink 35 is installed on the circuit board 33, and the heat sink 35 extends out of the box cover 306 of the electric control box 3. The connection method between the radiator 35 and the circuit board 33, the radiator 35 is provided with a seal 353 around the radiator 35; the structural form and arrangement method of the heat dissipation fins 352 in the radiator 35, the radiator 35 is above the inductor 34; the outer metal box of the electric control box 3 includes a patch block 32, and the patch block 32 is located above the inductor 34 to prevent direct sunlight; the circuit board 33 is installed on the plastic inner shell of the electric control box 3 seat by snap-fitting, and the structural shape of the plastic inner shell.

[0262] In the electric control box 3 of some embodiments of the present invention, since the electric control box 3 adopts the combination of the insulating inner shell 303 and the fireproof outer shell 304, there may be a problem of water ingress between the insulating outer shell and the fireproof inner shell, so it is necessary to guide the water in the insulating outer shell and the fireproof inner shell to a direction away from the internal space of the electric control box 3. For this reason, in some embodiments of the present invention, a drainage structure is provided for drainage. The box body 31 of the electric control box 3 can adopt the box body 31 structure described in other embodiments.

[0263] Specifically, if Figures 1 to 34 The electric control box 3 includes a box body 31. The box body 31 is arranged vertically, and the box body 31 has a first end (refer to the upper end of the box body 31 in the figure) and a second end (refer to the lower end of the box body 31 in the figure) opposite to each other in the vertical direction. The box body 31 includes an insulating inner shell 303 and a fireproof outer shell 304. The insulating inner shell 303 can ensure effective insulation between the circuit board 33 and the electric control box 3, and ensure the safety of the electric control box 3, while the fireproof outer shell 304 can effectively improve the fireproof performance of the electric control box 3, and even if the electric control box 3 fails to burn, it is arranged to prevent damage to the rest of the air conditioner or even cause a fire.

[0264] The insulating inner shell 303 is arranged vertically, and the fireproof outer shell 304 is arranged outside the insulating inner shell 303. A drainage groove 3049 is arranged between the fireproof outer shell 304 and the insulating inner shell 303, and the drainage groove 3049 extends vertically. During use, water may enter between the insulating inner shell 303 and the fireproof outer shell 304. At this time, the water between the insulating inner shell 303 and the fireproof outer shell 304 may penetrate into the electric control box 3, causing the electric control box 3 to malfunction. Therefore, the drainage groove 3049 is arranged in the present invention. Through the drainage of the drainage groove 3049, the water between the insulating inner shell 303 and the insulating outer shell can be drained to a predetermined position for discharge, thereby ensuring that the electric control box 3 can operate stably. The drainage groove 3049 extends to the first end of the box body.

[0265] According to the electric control box 3 of the embodiment of the present invention, a drainage groove 3049 is provided to drain water away from the inner space of the electric control box 3 .

[0266] In order to achieve the connection between the electric control box 3 and the shell of the outer box body 22, the outer box body 22 and the top of the fireproof outer shell 304 can be connected by a fixing part. At this time, it is necessary to set a positioning hole 3070 on the fireproof outer shell 304. The setting of the positioning hole 3070 may cause water to enter between the fireproof outer shell 304 and the insulating inner shell 303 along the fixing part.

[0267] Optionally, at the first end of the box body, a positioning hole 3070 is provided on the fireproof outer shell 304, and one end of the drainage groove 3049 extends to the first end and is vertically opposite to the positioning hole 3070. As mentioned above, water may enter between the fireproof outer shell 304 and the insulating inner shell 303 through the positioning hole 3070. At this time, since one end of the drainage groove 3049 is opposite to the positioning hole 3070, the water will flow under the drainage effect of the drainage groove 3049, thereby discharging the water entering between the fireproof inner shell and the insulating outer shell to an appropriate position.

[0268] In combination with the above-mentioned embodiment, the box body 31 includes: an insulating inner shell 303 and a fireproof outer shell 304 .

[0269] The insulating inner shell 303 includes a first inner shell 311 and a second inner shell 312 which are assembled in the longitudinal direction, and a drainage groove 3049 extending in the vertical direction is provided on the outer surface of the second inner shell 312; the fireproof outer shell 304 includes a first outer shell 313 and a second outer shell 314, the first outer shell 313 is covered outside the first inner shell 311, and the second outer shell 314 is covered outside the second inner shell 312, and the drainage groove extends to the first end of the box body.

[0270] Optionally, the second outer shell 314 is provided with an outer convex structure 3071 protruding vertically in a direction away from the second inner shell 312, and the positioning hole 3070 is provided on the outer convex structure 3071. In other words, at the first end of the box body 31, the fireproof outer shell 304 is provided with an outer convex structure 3071, and the positioning hole 3070 is provided on the outer convex structure 3071. Through the outer convex structure 3071, water entering between the inner and outer shells through the positioning hole 3070 can be reduced, thereby improving the stability and safety of the electric control box 3.

[0271] At the first end of the box body, a positioning hole 3070 is provided on the second shell 314 , wherein one end of the drainage groove 3049 extends to be vertically opposite to the positioning hole 3070 .

[0272] Optionally, at the first end of the box body, the edge of the second inner shell 312 is provided with a convex rib 3047 protruding vertically in a direction away from the internal space of the box body 31, and the convex rib 3047 is located at the first end of the box body 31 and vertically protrudes from the edge of the second outer shell 314. The convex rib 3047 can block media such as water, and block water outside the second outer shell 314, so that it does not flow to the matching position between the first inner shell 311 and the second inner shell 312, thereby effectively preventing water.

[0273] Optionally, the distance L1 between the rib 3047 and the positioning hole 3070 is not less than 6 mm, so as to ensure that the medium such as water does not flow to the joint between the first inner shell 311 and the second inner shell 312 .

[0274] Optionally, at the first end of the box body 31, the end surface of the second inner shell 312 is inclined toward the second end of the box body 31 in a direction away from the first inner shell 311 in the longitudinal direction. Water dripping onto the second outer shell 314 and water entering the second inner shell 312 will flow along the inclined end surface under the action of gravity, and will be prevented from flowing to the matching position of the first inner shell 311 and the second inner shell 312.

[0275] Optionally, at the first end of the box body 31, one end of the drainage groove 3049 extends to the end surface of the second inner shell 312 and forms a clearance groove 3050, the bottom surface of the clearance groove 3050 is spaced apart from the second outer shell 314, and the clearance groove 3050 is vertically opposite to the positioning hole 3070. By providing the clearance groove 3050, when the box body and the box body 31 of the window air conditioner 1000 are connected by the fixing member, the fixing member will not contact the second inner shell 312, ensuring that the second inner shell 312 is not damaged, and improving the waterproof performance of the electric control box 3. In addition, the clearance groove 3050 forms the entrance of the drainage groove 3049, which can discharge the water entering between the fireproof outer shell 304 and the insulating inner shell 303 as soon as possible.

[0276] Optionally, at the first end of the box body 31, at least a portion of the end surface of the second inner shell 312 is spaced apart from the second outer shell 314 and is provided with a plurality of ribs 3051, wherein the ribs 3051 extend vertically and longitudinally, and the plurality of ribs 3051 are arranged at intervals in the transverse direction, wherein a clearance groove 3050 is constructed between two adjacent ribs 3051.

[0277] Specifically, the insulating inner shell 303 is provided with a plurality of ribs 3051 at the first end, and the plurality of ribs 3051 are arranged at intervals in the horizontal direction (i.e., the left-right direction in the figure), and the ribs 3051 extend in the longitudinal direction (referring to the front-back direction in the figure). In this way, a groove is formed between two adjacent ribs 3051, which can receive water entering through the positioning hole 3070, and facilitates the water entering between the inner and outer shells to be handled.

[0278] In addition, the drainage groove 3049 is provided on the outer surface of the insulating inner shell 303. Generally, the insulating inner shell 303 is made of plastic, while the fireproof outer shell 304 is made of sheet metal. It is often easier to form the drainage groove 3049 on a plastic part than on a sheet metal part. Therefore, the present invention can effectively simplify the production process by providing the drainage groove 3049 on the insulating inner shell 303.

[0279] Furthermore, in combination with the sealing structure between the first inner shell 311 and the second inner shell 312 in the aforementioned embodiment, the waterproof performance of the electric control box 3 can be further improved.

[0280] Optionally, the top wall of the box assembly 2 is screwed to the first end of the electric control box 3. The screw connection can effectively improve the stability of the electric control box 3, especially during transportation and drop tests, the electric control box 3 can still maintain a stable state.

[0281] Optionally, the top wall of the box assembly 2 is provided with an inner concave structure 205, and the first end of the electric control box 3 is provided with an outer convex structure 3071, and the inner concave structure 205 and the outer convex structure 3071 are connected by a fixing member. The inner concave structure 205 of the box assembly 2 cooperates with the outer convex structure 3071 of the electric control box 3, which can facilitate the fixing member to connect the box assembly 2 and the electric control box 3, and the inner concave structure 205 can be used to accommodate the head of the screw to ensure the flatness of the outer surface of the box assembly 2.

[0282] The concave structure 205 can prevent the screw head of the outer box from protruding from the outer box surface. The screw recessed area is designed so that a small amount of rainwater will accumulate at this position. Therefore, the drainage groove 3049 is designed for the corresponding screw connection to prevent water droplets that penetrate from the screw hole of the outer box from remaining on the electric control box 3. The water is discharged into the chassis 1 along the drainage groove 3049 and reused for the second time (the condensed water in the chassis 1 is cooled by the axial fan 225 water ring to improve the product capacity and energy efficiency).

[0283] The electric control box 3 is installed vertically on one side of the outdoor air duct. To avoid large shaking, a screw is used to connect and fix the electric control box 3 to the outer box on the top. The opening of the outer box shutter part (that is, the air inlet 203 on the side of the outer box shell 221 facing away from the chassis 1) is located above the electric control box 3. The sheet metal cover of the electric control box 3 has no opening design to prevent water from outside from splashing into the electric control box 3.

A flange rib is provided on the periphery of the shutter, and the spacing between the flange rib and the convex rib is not less than 6 mm to facilitate air intake and heat dissipation of the electronic control box 3.

[0286] The louver is vertically opposite to the second housing 314, or the louver is vertically staggered from the first housing 313. When water enters the outer box 22 through the louver, it will splash onto the second housing 314. The water from the outside of the louver of the outer box only flows down to the top part of the cover of the sheet metal electric control box 3, and flows into the chassis 1 along the outer surface of the sheet metal electric control box 3. In addition, the periphery of the louver is provided with a flange rib 207 extending into the outer box 22, and the spacing L2 between the flange rib 207 and the aforementioned convex rib 3047 is not less than 6 mm. This is conducive to the removal of water from the top of the electric control box 3 to avoid entering the electric control box 3 and affecting product quality.

[0287] Optionally, a through heat dissipation hole 3059 is provided on the side wall of the insulating inner shell 303, and the heat dissipation hole 3059 is inclined toward the second end from the inside to the outside. In this way, the heat inside the insulating inner shell 303 will be dissipated through the heat dissipation hole 3059, and due to the protection of the fireproof outer shell 304 outside the insulating inner shell 303, external water, steam, etc. will not enter the box body 31 through the heat dissipation hole 3059, and the heat can be dissipated through the fireproof outer shell 304, so as to achieve the functions of waterproofing, fire prevention and heat dissipation.

[0288] Optionally, at least a portion of the peripheral wall of the heat dissipation hole 3059 extends out of the outer side of the insulating inner shell 303. The peripheral wall of the heat dissipation hole 3059 extends out to separate the insulating inner shell 303 from the insulating outer shell, so that an air flow channel is provided between the inner and outer shells for air flow, further improving the heat dissipation effect of the electric control box 3.

[0289] Optionally, the peripheral walls of the heat dissipation hole 3059 all extend out of the side of the insulating inner shell 303, the length of the side wall of the heat dissipation hole 3059 adjacent to the first end is longer than the length of the side wall of the heat dissipation hole 3059 adjacent to the second end, and the edge of the side wall of the heat dissipation hole 3059 adjacent to the first end is provided with a notch groove 3060. In this way, the heat dissipation hole 3059 will not be blocked by the fireproof outer shell 304, and the hot air inside the insulating inner shell 303 is conveniently sent out through the heat dissipation hole 3059, thereby improving the heat dissipation effect. In addition, the notch groove 3060 is provided on the heat dissipation hole 3059, which can facilitate the overall circulation of the airflow in the electric control box 3.

[0290] As mentioned above, in order to assist the internal heat dissipation of the electric control box 3, the present invention is designed with a slanted downward opening on the side wall of the second inner shell 312; the second outer shell 314 is designed without an opening, and the heat in the electric control box 3 can be transferred to the outer second outer shell 314 through the opening, so that the internal heat can be dissipated, reducing the internal temperature of the electric control box 3, which is beneficial to extending the life of electrical components; the side wall is designed with a slanted downward opening structure, which can prevent water from seeping into the gap between the top sheet metal cover of the electric control box 3, and can flow downward through the slanted hole to avoid flowing into the electric control box 3.
