The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0101] like Figure 1 The window air conditioner 1000 according to an embodiment of the present invention includes: a chassis 1 and a box assembly 2.

[0102] Among them, the chassis 1 can be used to provide support for the entire machine. At least part of the other components in the window air conditioner 1000 can be installed on the chassis 1. The box assembly 2 is installed on the chassis 1. The box assembly 2 can integrate a heat exchange module. For example, the box assembly 2 integrates indoor heat exchanger 212, outdoor heat exchanger 222, compressor 229 and other components.

[0103] Optionally, the window air conditioner 1000 of the present invention further includes an electric control box 3 , which is disposed in the cabinet assembly 2 . The electric control box 3 can be used to control components inside the cabinet assembly 2 .

[0104] Alternatively, as Figure 1 In the window air conditioner 1000 of the present invention, the cabinet assembly 2 includes an inner cabinet 21 and an outer cabinet 22. The inner cabinet 21 is mounted on the chassis 1. The outer cabinet 22 is mounted on the chassis 1, and the inner cabinet 21 and the outer cabinet 22 are spaced apart to form a receiving groove 206 for accommodating the window sash. During use, the window air conditioner 1000 can be placed on the window frame, with the receiving groove 206 facing the window sash. When the window sash needs to be closed, it can be inserted into the receiving groove 206. This facilitates the closing of the window sash, avoids the window sash being unable to open and close normally due to the setting of the window air conditioner 1000, and achieves effective isolation and insulation between indoor and outdoor.

[0105] Optionally, the electric control box 3 in the present invention is installed in the outer box 22 .

[0106] Optionally, the electric control box 3 is arranged in the outer box 22 adjacent to the inner box 21, thereby providing a larger space for the heat dissipation structure of the outer box 22, facilitating heat dissipation.

[0107] The outer box body 22 has an air inlet 203 and an air outlet 204, wherein an air inlet 203 is formed at the top of the outer box body 22 (away from the chassis 1), and the air inlet 203 is opposite to or staggered with the electric control box 3, wherein the air inlet 203 can be set to be opposite to the radiator 35 (for example, the air inlet 203 is opposite to the cooling fins 352), so that the air flow entering the outer box body 22 will be discharged after passing through the radiator 35 or the electric control box 3, thereby realizing heat dissipation of the electric control box 3.

[0108] Alternatively, as Figure 1FIG2 is a schematic diagram of a window air conditioner 1000 according to an embodiment of the present invention. The outer housing 22 includes an outer housing shell 221, an outdoor heat exchanger 222, and an outdoor air duct assembly 223. The side of the outer housing shell 221 facing away from the inner housing 21 is enclosed by the outdoor heat exchanger 222. The outdoor air duct assembly 223 is located inside the outdoor heat exchanger 222 (on the side adjacent to the inner housing 21). The outdoor air duct assembly 223 includes an outdoor motor 224 and axial flow blades 225. The axial flow blades 225 face the outdoor heat exchanger 222. The outdoor motor 224 is located inside and connected to the axial flow blades 225. The outdoor air duct assembly 223 also includes a rear panel 227 mounted on the chassis 1. The outdoor motor 224 is fixed to the rear panel 227. An air inlet is provided on at least one of the top surface (the surface facing away from the chassis 1), the left side surface, the right side surface and the rear end surface of the outer box shell 221 for air flow to pass through. Driven by the outdoor air duct assembly 223, the air flow flows along the air inlet, the electrical control box 3, the outdoor air duct assembly 223 and the condenser to form a heat exchange channel to dissipate heat to the outdoor heat exchanger 222, the electrical control box 3, etc.

[0109] The inner housing 21 includes an inner housing shell 211, an indoor heat exchanger 212, and an indoor air duct assembly. The inner housing 21 is formed with a return air inlet 201 and a supply air inlet 202. The indoor air duct assembly is disposed within the inner housing shell 211 and drives airflow from the return air inlet 201 to the supply air inlet 202. The return air inlet 201 is disposed on a surface of the inner housing 21 away from the outer housing 22. Alternatively, the return air inlet 201 may be disposed on the chassis 1 or on other surfaces of the inner housing 21. The indoor heat exchanger 212 is disposed between the indoor air duct assembly and the return air inlet 201. The inner housing 21 also includes a control box 213, which is disposed at an end of the inner housing 21 away from the outer housing 22. The indoor air duct assembly includes a crossflow impeller 214. In addition, the air supply port 202 is arranged on the upper part of the inner box shell 211 away from the outer box body 22, and the air supply port 202 is constructed to supply air in a direction away from the outer box body 22. The air supply port 202 can also be arranged to be inclined in a direction away from the outer box body 22 and away from the chassis 1.

[0110] An air guide plate 215 is provided at the air outlet 202, and the air guide plate 215 can be rotated to adjust the air supply angle. In addition, a horizontal swing blade 216 can be provided on the inside of the air guide plate 215, and a protective mesh cover 217 is provided on the inside of the air outlet 202 to prevent hands or other objects from entering the air duct.

[0111] A middle partition 23 is provided between the inner box body 21 and the outer box body 22. The middle partition 23 is provided in the space between the inner box body 21 and the outer box body 22 adjacent to the chassis 1. A channel for at least one of the water supply flow, wiring harness, refrigerant pipe, etc. can be formed between the middle partition 23 and the chassis 1 to realize communication and signal transmission between the inner and outer boxes 22.

[0112] Optionally, in the aforementioned embodiment, the window sash can be closed through the accommodating groove 206. Due to the existence of the chassis 1 and the connection structure between the inner box body 21 and the outer box body 22, although the window sash can be closed, a certain gap will still remain.

[0113] Optionally, the window air conditioner 1000 of the present invention further includes a sealing block. When deployed, the sealing block is positioned on at least one of the two outer sides of the chassis 1 to seal the gap between the window sash and the window frame. The sealing block can seal the unsealed portion between the window sash and the window frame, effectively sealing the room and reducing leakage of cold or hot air.

[0114] Optionally, the sealing block further has a retracted position, at which the sealing block is received in the box assembly 2. Optionally, the sealing lead of the present invention can be received in the aforementioned receiving groove 206 at the retracted position.

[0115] Optionally, the fixing member in the present invention may be a screw, a pin, a rivet, etc.

[0116] Optionally, in combination with the above embodiments and Figures 1 to 7 The outer housing 22 includes an outer housing 221, which includes a panel 227 and a top cover 228. The panel 227 is connected to the chassis 1 and extends perpendicularly thereto. The top cover 228 covers the side of the panel 227 away from the chassis 1. The top cover 228 and the panel 227 are connected by fixings. A recess 3012 is provided on the electric control box 3 at a position corresponding to the fixing connecting the panel 227 and the top cover 228. The recess 3012 facilitates the connection between the fixings and the top cover 228, thereby improving the structural strength of the outer housing 22. It also prevents the fixings from scratching the surface of the electric control box 3, thereby preventing rust or corrosion caused by paint peeling from the surface of the electric control box 3.

[0117] Optionally, the position of the enclosing plate 227 opposite to the recess 3012 is convex, thereby facilitating the connection between the enclosing plate 227 and the top cover 228, and also facilitating the connection of the enclosing plate 227 and the top cover 228 with a fixing member.

[0118] like Figure 5 and Figure 6 , showing a schematic diagram of the outer housing 221 and its coordination with the electrical control board. The outer housing 221 surrounds a panel 227 and a top cover 228. The panel 227 is U-shaped, with its open side sealed by the outdoor heat exchanger 222. Air inlets 203 are provided on three sides of the panel 227 and the top cover 228. The electrical control box 3 is positioned adjacent to the sidewall of the outer housing 221, near the inner housing 21. A recess 3012 is provided on the electrical control box 3, and the outer housing 221 has a protruding portion corresponding to the recess 3012.

[0119] The following describes the installation structure of the electric control box 3 in an 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 together and positioned on the chassis 1 by fixings. For example, after the electric control box 3 and the chassis 1 are plugged together, the electric control box 3 and the chassis 1 are pre-positioned, and then the electric control box 3 and the chassis 1 are fixed together by fixings.

[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 stable support for the electric control box 3. By plug-in and positioning with fixing parts, the electric control box 3 can be quickly installed. Moreover, plug-in can play a certain pre-positioning role. Through the pre-positioning of plug-in, the electric control box 3 and the chassis 1 can be quickly positioned by fixing parts.

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

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

[0123] Alternatively, as Figures 7 to 10 The chassis 1 is provided with a socket 101, which can be opened horizontally (refer to the left-right direction in the drawings). A latch 301 is provided at one end of the bottom of the electric control box 3 in the horizontal direction. The latch 301 is inserted into the socket 101 in the horizontal direction and is parallel to the chassis 1. By cooperating with the socket 101 and the latch 301 in the horizontal direction parallel to the chassis 1, the latch 301 can be quickly inserted into the chassis 1, and the electric control box 3 and the chassis 1 can be conveniently connected via the fixing parts.

[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 hook-shaped, 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 this does not limit the scope of protection of the present invention.

[0125] In addition, the electric control box 3 in the present invention can also be plugged into 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 longitudinal 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, as Figures 7 to 10 A portion of the chassis is raised to form a socket. Specifically, referring to the accompanying drawings, a portion of the chassis is raised upward to form the socket, and the edge of the top wall of the socket extends obliquely to form a flared shape. Specifically, the edge of the top wall of the socket 101 is configured to extend obliquely upward, so that the opening of the socket 101 is configured to be flared. During the process of plugging the latch 301 into the socket 101, the latch 301 can quickly engage with the socket 101, facilitating the rapid engagement of the latch 301 with the socket 101 and improving assembly efficiency.

[0128] Alternatively, as Figures 7 to 10 The sidewall edge of the socket 101 is provided with a notch 102. As shown in the figure, the front and rear sidewalls of the socket 101 are provided with a notch 102. In this way, the opening of the socket 101 will form a larger flared shape, further facilitating the fit of the latch 301 and the socket 101, so that the latch 301 can be quickly inserted into the socket 101, and the latch 301 and the socket 101 can be quickly positioned.

[0129] Alternatively, as Figures 7 to 10 A clearance notch 309 is provided at a position where the electrical control box 3 is opposite to the socket 101. The clearance notch 309 can provide a clearance structure, for example, to allow for the socket 101, to allow for a wiring structure, etc., and can also provide a larger installation space for easier 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 the up and down direction as shown in the figure), and the second surface is opposite to the socket 101 in the 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 latch 301 is connected to the connecting portion 3043. That is, the latch 301 structure is provided at the clearance notch 309, which can facilitate the quick matching of the latch 301 and the socket 101, and the structural strength of the clearance notch 309 can be improved through the connection of the connecting portion 3043. Moreover, the overall structure of the electrical control box 3 is simplified.

[0130] Alternatively, as 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 (downward in the figure). The latch 301 is connected to the free end of the first connecting rod 3044. This facilitates the insertion and mating of the latch 301 with the socket 101. Furthermore, the provision of the clearance notch 309 provides greater visual space, facilitating the insertion 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 connecting portion 3043 further includes a reinforcing rib 3046, which is connected between the first surface, the second surface, the first connecting rod 3044, and the second connecting rod 3045. The provision of the reinforcing rib 3046 can effectively improve the structural strength of the connecting portion 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 hollow ring 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, allowing air flow to pass through to enhance heat dissipation of the electric control box 3.

[0134] In addition, a wire outlet 3013 can be provided at the clearance notch 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 can be provided in a U-shape extending along the first connecting rod 3044, the second connecting rod 3045, and the second surface.

[0135] Alternatively, as Figures 1 to 10 The chassis 1 is provided with a first protrusion 11, and the socket 101 is located on the top wall of the first protrusion 11. Thus, after the latch 301 is inserted into the socket 101, a certain space is left between the latch 301 and the bottom surface of the chassis 1, and the latch 301 does 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. Furthermore, the provision of the first protrusion 11 prevents water from entering the electrical control box 3 through siphoning or other effects.

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

[0137] Alternatively, as Figures 7 to 10Mounting portions 302 extend longitudinally from two longitudinally opposite sides of the electric control box 3. That is, the mounting portions 302 extend from the front and rear sides of the electric control box 3. This facilitates connection between the mounting portions 302 and the chassis 1 via fixings, effectively improving the connection efficiency between the electric control box 3 and the chassis 1.

[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. Utilizing the fixing members arranged in a triangular shape, a stable positioning structure 3019 can be formed, facilitating a stable connection between the electric control box 3 and the chassis 1 .

[0139] Of course, the triangular arrangement of the fixing members in the present invention is only one embodiment of the present invention. The fixing members 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 members can be set. Due to the coordination of the plug-in and the fixing members, the electric control box 3 and the chassis 1 can also be quickly positioned.

[0140] Alternatively, as 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, preventing condensed water on the chassis 1 from entering the interior of the electric control box 3. In addition, it can facilitate the installation of the electric control box 3 and prevent the fixing parts from forming a protruding structure on the bottom surface of the chassis 1. This effectively improves the stability of the cooperation between the electric control box 3 and the chassis 1 and facilitates the installation of the chassis 1 on other equipment or structures.

[0141] Optionally, a groove (not shown) 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. This can reduce the mating area between the electric control box 3 and the chassis 1, thereby facilitating a stable mating between the electric control box 3 and the chassis 1 and facilitating airflow between the electric control box 3 and the chassis 1, thereby preventing heat accumulation and facilitating heat dissipation.

[0142] Optionally, in the present invention, the aforementioned first bulge 11 is higher than the height of the second bulge 12, that is, the plug-in structure of the electric control box 3 and the connection 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, as Figure 8The 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 a portion of the outer box 22. The bottom of the electric control box 3 adjacent to the compressor 229 is plugged into the chassis 1, and 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 fixings. The plug-in structure has relatively small requirements for 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 fixings at the end away from the compressor 229. This can improve the coordination 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.

[0144] Figure 8 The figure shows the positional relationship between the chassis 1, outdoor duct assembly 223, electrical control box 3, and compressor 229 in a window air conditioner 1000 according to one embodiment of the present invention. The outdoor duct assembly 223, electrical control box 3, and compressor 229 are all mounted on the chassis 1 and located at the rear end of the chassis 1. The electrical control box 3 is located in front of the outdoor duct assembly 223. An opening is provided at the front end of the chassis 1 for ventilation. The end of the electrical control box 3 adjacent to the compressor 229 plugs into the chassis 1, while the end of the electrical control box 3 away from the compressor 229 is fixed to the chassis 1 by fasteners (such as screws). The chassis 1 is provided with a first protrusion 11 and a second protrusion 12. The electrical control box 3 plugs into the first protrusion 11 and is connected to the second protrusion 12 by fasteners.

[0145] Optionally, the electric control box 3 is erected on the chassis 1. This facilitates heat dissipation of the electric control box 3 and also reduces the space occupied by the electric control box 3, thereby improving space utilization.

[0146] The structure of the electric control box 3 of the present invention will be described below with reference to the accompanying drawings. The electric control box 3 can be applied to any other window air conditioner 1000 of the present invention, and can also be applied to other air conditioners, fresh air blowers, kitchen appliances and other equipment.

[0147] like Figure 7 As shown, the electric control box 3 according to an embodiment of the present invention includes a box body 31, which comprises an insulating inner shell 303 and a fireproof outer shell 304. The insulating inner shell 303 defines a cavity, and the fireproof outer shell 304 covers the outer surface of the insulating inner shell 303. The insulating inner shell 303 effectively insulates the circuit board 33 from the electric control box 3, ensuring the safety of the electric control box 3. The fireproof outer shell 304 effectively enhances the fire resistance of the electric control box 3. Even if the electric control box 3 malfunctions and burns, it will not damage the rest of the air conditioner or cause a fire.

[0148] The insulating inner shell 303 in the present invention may be a plastic inner shell, and the fireproof outer shell 304 may be a metal shell.

[0149] Alternatively, as Figures 7 to 15 The insulating inner housing 303 comprises a first inner housing 311 and a second inner housing 312 that are joined together longitudinally. This joining of the first and second inner housings 311, 312 facilitates the molding of the insulating inner housing 303 and the installation of electronic components 331, circuit boards 33, and other components within the electrical control box 3, improving assembly efficiency and facilitating maintenance.

[0150] The first inner shell 311 and the second inner shell 312 are joined together to form a relatively closed space.

[0151] Alternatively, as Figures 7 to 15 The fireproof outer shell 304 includes a first outer shell 313 and a second outer shell 314. The first outer shell 313 is arranged outside the first inner shell 311, and the second outer shell 314 is arranged outside the second inner shell 312. It can effectively prevent fire, improve the safety performance of the air conditioner, and facilitate the maintenance of the electric control box 3.

[0152] Optionally, in combination with the aforementioned embodiment, the first inner shell 311, the second inner shell 312, the first outer shell 313, and the first outer shell 314 are all erected on the chassis 1. The first inner shell 311 and the second inner shell 312 are assembled in a direction parallel to the chassis 1 (e.g., the longitudinal direction described above). This further facilitates the installation of the electrical control box 3 and improves the assembly efficiency and stability of the electrical control box 3.

[0153] Optionally, the first inner shell 311 can be made of plastic, for example, by injection molding as an integral structure. Furthermore, the second inner shell 312 can also be made of plastic and can also be formed as an integral structure by injection molding. The first outer shell 313 and the second outer shell 314 can be made of metal, for example, by sheet metal molding. In other words, in one optional embodiment of the present invention, the first outer shell 313 and the second outer shell 314 are integrally formed using sheet metal.

[0154] Optionally, the first inner shell 311 and the second inner shell 312 are connected by snaps or screws. The first outer shell 313 and the first outer shell 314 are connected by snaps or screws. This forms a stable connection structure between the first inner shell 311 and the first outer shell 313, and between the second inner shell 312 and the second outer shell 314, thereby improving the stability of the box body 31.

[0155] Specifically, a first snap-fit ​​structure 3014 is provided on the outer periphery of the first inner shell 311, and a second snap-fit ​​structure 3040 is provided on the outer periphery of the second inner shell 312. The first snap-fit ​​structure 3014 is snap-fitted to the second snap-fit ​​structure 3040. Optionally, one of the first snap-fit ​​structure 3014 and the second snap-fit ​​structure 3040 may be a hook, and the other may be a protrusion 3069, thereby quickly and stably connecting the first inner shell 311 and the second inner shell 312 together through the snap-fit ​​structure.

[0156] Optionally, a first ear portion 3065 extends from the periphery of the first outer shell 313, and a second ear portion 3067 extends from the periphery of the second outer shell 314. The first ear portion 3065 and the second ear portion 3067 are fixedly connected by a fixing member. The fixing member can stably connect the first outer shell 313 and the second outer shell 314 together. In addition, because the first outer shell 313 is covered by the first inner shell 311 and the second outer shell 314 is covered by the second inner shell 312, the connection between the first outer shell 313 and the second outer shell 314 can stably assemble the entire box body 31 structure.

[0157] Optionally, the first inner shell 311 and the first outer shell 313 are connected by snaps or screws. Specifically, a protrusion can be provided on the outer surface of the first inner shell 311, and a through hole can be provided on the peripheral wall of the first outer shell 313. The protrusion and the through hole can cooperate to achieve a snap fit between the first inner shell 311 and the first outer shell 313. In addition, screws can be used in combination or alone to connect the first inner shell 311 and the first outer shell 313.

[0158] Optionally, the second inner shell 312 is snap-fitted or screw-connected to the second outer shell 314. Specifically, a protruding buckle can be provided on the outer surface of the second inner shell 312, and a through hole can be provided on the peripheral wall of the second outer shell 314. The protruding buckle and the through hole can cooperate to achieve a snap-fit ​​connection between the second inner shell 312 and the second outer shell 314. In addition, screw connection can be used in combination or alone to connect the second inner shell 312 and the second outer shell 314.

[0159] In addition, the first inner shell 311 and the second inner shell 312 can also be connected by fasteners, and the first outer shell 313 and the second outer shell 314 can also be connected by snaps. In the present invention, any of the first inner shell 311 and the first outer shell 313, the second inner shell 312 and the second outer shell 314, or the first inner shell 311 and the second inner shell 312, or the first outer shell 313 and the second outer shell 314 can also be connected using a combination of snaps and fasteners.

[0160] The first outer shell 313 and the second inner shell 312 of the present invention may be provided with the aforementioned mounting portion 302 and other structures. For example, the aforementioned latch 301 is provided on the insulating inner shell 303 and extends out of the fireproof outer shell 304, and the aforementioned connecting portion 3043 is also provided on the insulating inner shell 303 and extends out of the fireproof outer shell 304, thereby facilitating the molding of the latch 301 and the connecting portion 3043.

[0161] In addition, from another perspective, the box body 31 may be composed of a box base 305 and a box cover 306 , wherein the box base 305 may be composed of a first inner shell 311 and a first outer shell 313 , and the box cover 306 may be composed of a second inner shell 312 and a second outer shell 314 .

[0162] Optionally, in combination with the above embodiment, the box body 31 is provided with a connecting portion 3043, wherein the connecting portion 3043 can be provided on the second inner shell 312 and is not covered by the fireproof outer shell 304. The above-mentioned mounting portion 302 can be formed on the fireproof outer shell 304.

[0163] Among them, the latch 301 is arranged on the second inner shell 312, and the latch 301, the connecting portion 3043 and the second inner shell 312 are injection molded as a whole. The first outer shell 313 is provided with a mounting portion 302, and the mounting portion 302 extends in a direction away from the second outer shell 314; the bottom of the first inner shell 311 is provided with a mounting portion 302, and one end of the mounting portion 302 extends in a direction away from the first outer shell 313. Both mounting portions 302 are connected to the chassis 1 through fixing parts.

[0164] Figure 9 and Figure 10 They are schematic diagrams of the matching structure of the chassis 1 and the electric control box 3 in different directions in a window fan air conditioner according to an embodiment of the present invention, Figure 9-1 yes Figure 9 A partial enlarged schematic diagram of the middle circle D area, Figure 10-1 yes Figure 10 A partial enlarged schematic diagram of the middle circle E area. Figure 9 and Figure 10 As shown, a socket 101 is provided on the first bulge, wherein the socket 101 is constructed in a flared form, and notches 102 are provided on the front and rear sides of the socket 101, a clearance notch 309 is provided on the electrical control box 3, and a connecting portion 3043 with a hollow structure composed of a first connecting rod 3044, a second connecting rod 3045, and a reinforcing rib 3046 is provided in the second socket 101, and the pin 301 is connected to the end of the first connecting rod 3044.

[0165] Figure 12 and Figure 13Schematic diagrams illustrating the second inner shell 312 and second outer shell 314 (i.e., the cover 306) of the electrical control box 3 in different orientations are shown. The aforementioned connecting portion 3043 and support structure are both located on the second inner shell 312. The second outer shell 314 covers the outer shell of the second inner shell 312 but does not cover the connecting portion 3043 and support structure. The cover 306 has a clearance opening 3058, through which the heat sink 35 engaged with the circuit board 33 on the box base 305 can pass, thereby improving the heat dissipation effect on the circuit board 33.

[0166] The fireproof shell 304 adopts rustproof sheet metal or surface sprayed sheet metal to achieve rust and fire prevention, and the product is safe and reliable.

[0167] The socket 101 is formed on the upper convex surface and is in a flared form. On the side away from the compressor 229, the plastic inner shell of the electric control box 3 is locked to the chassis 1 by two screws and the metal outer shell of the electric control box 3 is locked by one screw, a total of three screws.

[0168] In the present invention, the cooperation of the box seat 305 and the box cover 306 is provided with a sealing structure. In addition, the electric control box 3 can be placed on the inner side of the heat dissipation fan in the outer box body 22.

[0169] In some embodiments of the present invention, a sealing structure is provided at the connection between the first inner shell 311 and the second inner shell 312 , and the sealing structure can improve the waterproof performance of the electric control box 3 .

[0170] like Figure 16 and Figure 18 A sealing groove 3015 is formed on the peripheral wall of the first inner shell 311, facing the second inner shell 312. A sealing rib 3041 is formed on the second inner shell 312, facing the first inner shell 311. The sealing rib 3041 is embedded in the sealing groove 3015. This forms a sealing structure, achieving a seal between the first inner shell 311 and the second inner shell 312.

[0171] Optionally, a sealing ring 3016 is provided in the sealing groove 3015, and the sealing rib 3041 presses against the sealing ring 3016. By providing the sealing ring 3016, the sealing between the first inner shell 311 and the second inner shell 312 can be further effectively achieved.

[0172] Specifically, the first inner shell 311 includes a first end plate and a first peripheral wall extending from the periphery of the first end plate. The second inner shell 312 includes a second end plate and a second peripheral wall extending from the periphery of the second end plate. The first outer shell 313 is disposed outside the first inner shell 311 and covers the first end plate and the first peripheral wall. The second outer shell 314 is disposed outside the second inner shell 312 and covers the second end plate and the second peripheral wall. The end surface of the first peripheral wall is provided with the aforementioned sealing rib 3041, and the end surface of the second peripheral wall is provided with the aforementioned sealing groove 3015. A sealing ring 3016 is disposed within the sealing groove 3015. The sealing rib 3041 is embedded in the sealing groove 3015 and presses against the sealing ring 3016 to achieve a seal.

[0173] like Figure 16 and Figure 18 , schematic diagrams showing the mating of the first inner shell 311 and the first outer shell 313 of the electric control box 3 (i.e., the box seat 305) in different orientations are shown. It can be seen that a sealing groove 3015 is provided on the periphery of the first inner shell 311, into which a sealing ring 3016 can be disposed. A corresponding structure on the second inner shell 312 can be inserted into the sealing groove 3015 and press against the sealing ring 3016, thereby achieving sealing of the electric control box 3, particularly the clearances between the upper, left, and right sides of the electric control box 3.

[0174] In addition, in order to improve the sealing performance of the sealing structure, in the present invention, a fixing member is provided at a position adjacent to the sealing ring 3016. In this way, through the connection of the fixing member, the sealing rib 3041 can be pressed more tightly against the sealing ring 3016, 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, Figure 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, as Figure 16 and Figure 18 The inner side of the peripheral wall of the second inner shell 312 is provided with a first slot 3042 that opens toward the first inner shell 311. The peripheral wall of the first inner shell 311 is embedded in the first slot 3042, and a sealing rib 3041 is provided on the inner bottom surface of the first slot 3042. The peripheral wall of the first inner shell 311 cooperates with the first slot 3042, and the sealing rib 3041 cooperates with the sealing groove 3015, forming a circuitous joint surface at the junction of the first inner shell 311 and the second inner shell 312, thereby effectively preventing water and other substances from entering the interior of the electric control box 3.

[0176] Optionally, a rib 3047 is provided on the peripheral edge of the second inner shell 312, 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 rib 3047 is provided on the outer peripheral surface of the second inner shell 312, when a medium such as water enters the outer peripheral surface of the second inner shell 312, the rib 3047 blocks the water and other media from entering the joint between the first inner shell 311 and the second inner shell 312, further effectively improving the waterproof performance of 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 electronic 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. Among them, 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 drafted outward to facilitate 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 electronic control box 3.

[0178] Optionally, the ribs 3047 protrude from the inner or outer circumference of the second outer shell 314. In this way, when water or other media already exists on the second outer shell 314, the ribs 3047 can also effectively block it and prevent the water or other media from flowing toward the junction 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, assembly efficiency and fireproof and waterproof performance can be improved.

[0180] For example, Figure 16 and Figure 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 of the longitudinal direction.

[0181] Alternatively, as Figure 16 and Figure 18 A recessed structure is provided on the outer surface of one end portion of the electric control box along the vertical direction, and the other end portion 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, and the electric control box 3 is arranged vertically. The recessed structure 307 is provided at one end portion of the electric control box 3 along the vertical direction, and the other end portion 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. Relatively speaking, a convex structure will exist on the other vertical end of the electric control box 3. That is to say, a recessed structure 307 is formed on the outer surface of the box body 31 at one vertical end and a convex structure is formed at the other end.

[0183] Among them, such as Figure 16 and Figure 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 intersection of the recessed structure 307 and the raised structure (i.e., the step). The gap 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.

[0185] It should be noted that the box body 31 of the present invention includes an insulating inner shell 303 and a fireproof outer shell 304. The fireproof outer shell 304 is generally formed using sheet metal. For example, if the sheet metal is formed into a rectangular parallelepiped structure, a portion of one side of the rectangular parallelepiped is recessed to form a recessed structure 307. This recessed structure 307 will have a height difference from the non-recessed portion, thus forming an opening at the junction of the recessed structure 307 and the non-recessed portion. This opening can be sealed using sheet metal processing, but this sheet metal processing is relatively expensive. Therefore, the present invention provides a patch block 32 to seal this opening. Furthermore, the patch block 32 is intended to seal the opening in the fireproof outer shell 304, while the insulating inner shell 303 can be injection molded without forming an opening. Therefore, the provision of the patch block ensures the relative integrity of the fireproof outer shell 304, thereby improving the fireproof performance of the electrical control box 3.

[0186] Furthermore, the electrical control box 3 of the present invention can be arranged in an upright position, with the recessed structure 307 disposed on the upper portion of the box body 31 and the raised structure disposed on the lower portion. When the electrical control box 3 is placed outdoors, sunlight may shine on the electrical control box 3, particularly where the patching block 32 is located. Without the patching block 32, sunlight could damage the electrical control box 3 (insulating inner shell 303). Therefore, the patching block 32 effectively protects the electrical control box 3 and improves its operational stability.

[0187] Specifically, since the box body 31 includes an insulating inner shell 303 and a fireproof outer shell 304, the fireproof outer shell 304 is provided with an opening due to the aforementioned drop, which will result in a portion of the insulating inner shell 303 being exposed. The insulating inner shell 303 is generally made of plastic, and this exposed portion is easily damaged by sunlight. Therefore, the present invention provides a patch block to prevent direct sunlight from shining on the plastic part, thereby effectively protecting the box body 31. In addition, in combination with Figure 16 and Figure 18 The end of the protruding structure facing the concave structure 307 is covered by a patch block 32. The patch block 32 maintains the integrity of the electric control box 3, effectively protects the interior space of the box body 31, and maintains 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 (eg, a reinforcement structure formed by stamping) is provided at the recessed structure 307 and its vicinity. The reinforcement structure may bridge the recessed structure 307, the convex structure, and the areas near the recessed structure 307 and the convex structure.

[0189] Alternatively, as Figure 13 and Figure 18 The patching piece 32 includes a cover plate 321, which covers the step between the raised structure and the recessed structure 307. A first flange 322 extending vertically toward the recessed structure 307 is formed along a portion of the circumference of the cover plate 321. The first flange 322 is connected to the wall of the recessed structure 307. A second flange 323 extending vertically toward the raised structure is formed along another portion of the circumference of the cover plate 321. The second flange 323 is connected to the wall of the raised structure. The first flange 322 and the second flange 323 ensure a stable connection between the patching piece 32 and 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, which is connected to the wall of the raised structure.

[0191] Alternatively, as Figures 13 to 18 A 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 buckle 324 extending vertically toward the cover plate 321 is formed on the first flange 322. The buckle 324 is vertically inserted into the insertion hole 3068. Figures 13 to 18 A locking protrusion 3069 is provided on the outer peripheral surface of the raised 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 patching piece 32 will be installed from top to bottom. At this time, the socket 101 on the first flange 322 will be inserted into the socket 3068, and the locking hole 325 on the second flange 323 will cooperate with the locking hole 325, thereby completing the positioning of the patching piece 32.

[0193] The patching block 32 can be installed by the above-mentioned snap-fit ​​structure. However, the snap-fit ​​structure is easily dislodged by external forces. Therefore, the present invention further provides a fixing member to connect the patching block 32 and the box body 31. After the patching block 32 is pre-positioned by snapping and plugging, the fixing member is used to fasten the patching block 32 and the box body 31.

[0194] Among them, such as 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 the shape of a rectangular parallelepiped, and a portion of one side of the box body 31 is recessed to form a square recessed structure 307. In this way, a generally 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 321. The recessed structure 307 formed at this 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 this side of the box body 31 will also form two adjacent surfaces that are generally at right angles, which are connected to the two adjacent surfaces by two second flanges 323.

[0198] The aforementioned recessed structure 307 is provided 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 buckle + snap connection structure. 6 "E"-shaped reinforcing ribs 3046 are designed in the recessed part of the electric control box 3, and the second outer shell 314 is assembled with a snap 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 in 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 reactor 34 is provided in the box body 31 of the electric control box 3, and at least a portion of the reactor 34 is disposed within the protruding structure, thereby effectively utilizing the internal space of the box body 31 and improving space utilization.

[0202] like Figures 1 to 34 In some embodiments of the present invention, the electric control box 3 includes a box body 31 and a circuit board 33. The circuit board 33 is disposed within the box body 31 and includes electronic components 331. By integrating the circuit board 33 within 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 electrical control box 3 in this embodiment can adopt the structure of the electrical control box 3 in other embodiments, and the structure of the electrical 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 electrical control box 3. Furthermore, when the electrical control box 3 is applied to the window air conditioner 1000, the installation method of the electrical control box 3 in the aforementioned window air conditioner 1000 can also be adopted.

[0204] In combination with the above 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] Furthermore, in combination with the above embodiment, the circuit board 33 is mounted on the first inner shell 311. 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. 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. Figure 20Positioning ribs 3020 are provided in the direction surrounding the circuit board 33. The positioning ribs 3020 form a circuit board 33 placement area around the circuit board 33, and the circuit board 33 is placed in the space formed by the positioning ribs 3020. In addition, the positioning hooks 3021 are used to position the circuit board 33. Positioning ribs 3020 are also provided between the circuit board 33 and the inner surface of the electric control box 3. The positioning ribs 3020 can separate the circuit board 33 from the inner surface of the electric control box 3, thereby facilitating 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, facilitating airflow and forming 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 spaced apart and arranged around the circuit board 33 .

[0208] Optionally, guide ribs 3022 are provided on the peripheral wall of the placement space. The guide ribs 3022 are perpendicular to the circuit board 33 and connect the inner side surface and inner bottom surface of the placement space. The end of the guide rib 3022, which is away from the inner bottom surface of the placement space, is configured as a wedge-shaped structure, with the height relative to the inner side surface of the placement space gradually increasing toward the inner bottom surface. This wedge-shaped structure can guide 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 on the edge of the circuit board 33, and a positioning protrusion 3072 is provided within the box body 31. The positioning protrusion 3072 cooperates with the positioning notch 102 to position the circuit board 33. The cooperation between the positioning notch 102 and the positioning protrusion 3072 allows foolproof installation of the circuit board 33, allowing the circuit board 33 to be installed in a predetermined orientation, preventing incorrect installation and improving 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 condensation water.

[0212] Optionally, a wiring groove 3027 is provided in the electric control box 3 around the circuit board 33. The wiring groove 3027 is provided with wire spurs 3031 for separating the wire harnesses. The electric control box 3 is provided with wire fixing ribs 3033 arranged at intervals along the extension direction of the wiring groove 3027 to position the wire harnesses.

[0213] The at least two wire drawing grooves include a weak-current wire drawing groove close to the circuit board and a strong-current wire drawing groove far away from the circuit board, and the separation of strong and weak currents is achieved through wire drawing ribs.

[0214] like Figure 21 and Figure 22 The electric control box 3 further includes a reactor 34 , which is disposed in the box body 31 , and the circuit board 33 and the reactor 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, which can 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, thereby facilitating the modular design, production, installation and maintenance of the window air conditioner 1000.

[0217] Alternatively, as Figure 24 A partition wall 3018 is provided in the box body 31, which separates the circuit board 33 and the reactor 34, and a wire opening 3037 is provided on the partition wall 3018 to connect the cavities where the circuit board 33 and the reactor 34 are located.

[0218] Reactor 34 can be connected to circuit board 33. The separation wall 3018 allows circuit board 33 and reactor 34 to perform their respective functions, preventing mutual interference. Furthermore, the wall 3018 provides a certain degree of thermal insulation, preventing thermal interaction between the circuit board 33 and reactor 34. A wire opening 3037 in the wall 3018 allows for the passage of wires to connect circuit board 33 and reactor 34.

[0219] The partition wall 3018 on the box body 31 may be an annular structure, and the reactor 34 is disposed inside the annular 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. This facilitates the stable connection between the reactance 34 and the box body 31 and improves the stability of the reactance 34 .

[0221] Optionally, the reactor 34 is provided in the box body 31 , and at least one of a grounding connector and a grounding mark is provided on the outside of the box body 31 at a position opposite to the reactor 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 grounding and two connecting the reactance 34, and the multiple screws are located in the inner recess (i.e., the recess formed by the sinking structure 3066 on the outer surface of the box body 31) to avoid exposure of the screw heads.

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

[0224] Alternatively, as Figure 31 The first inner shell 311 is provided with an escape opening 3038, and the reactor 34 is provided in the escape opening 3038 and directly mounted on the first outer shell 313. The escape opening 3038 can be formed by surrounding the aforementioned partition wall 3018.

[0225] Optionally, combined Figures 1 to 18 A portion of the first housing 313 is sunken to form a sunken platform structure 3066 on the inner side of the first housing 313, and the reactor 34 is mounted on the sunken platform structure 3066. This will provide more installation space for the reactor 34, and the reactor 34 can be connected to the sunken platform structure 3066 via a fixing member. Since the sunken platform structure 3066 forms a depression on the outer surface of the box body 31, when the reactor 34 and the sunken platform are connected via the fixing member, the fixing member will extend into the depression formed by the sunken platform structure 3066, effectively protecting the smooth appearance of the electric control box 3, preventing the fixing member from protruding from the outer surface of the electric control box 3, and preventing the screw heads for fixing the reactor 34 and the grounding screw heads from protruding from the outer surface of the electric control box 3, thereby preventing injuries during assembly or component transportation.

[0226] In addition, the sinking structure 3066 can also serve as a reinforcement structure.

[0227] Furthermore, a grounding structure can be provided within the recess formed by the sunken platform structure 3066 to achieve grounding, further improving the safety of the operation of the electric control box 3. The reactor 34 is mounted on the sunken platform structure 3066 at the bottom of the box body 31. This not only strengthens the structural strength of the sheet metal bottom plate 351, but also prevents the heads of the screws securing the reactor 34 and the grounding screws from protruding from the electric control bottom plate 351, thus preventing 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 clearance opening 3058 can be provided on the clearance structure.

[0231] In addition, at least a portion of the reactor 34 in the present invention may be disposed in the protruding structure corresponding to the recessed 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 set below the circuit board 33 to lower the center of the electric control box 3 and improve stability. In addition, Figures 16 to 26 Reactor 34 is positioned on the box body 31 using a buckle 324 and a fixing member, thereby stably fixing reactance 34 to the box body 31. Reactor 34 is equipped with a grounding screw and a grounding mark, where the grounding screw extends from the inside of the box body 31. Specifically, because reactance 34 is heavy, to ensure the stability of the center of gravity of the electric control box 3, reactance 34 is fixed below the first housing 313. Mounting on the first housing 313 not only facilitates heat dissipation, but also provides a strong and reliable structure.

[0233] Optionally, the circuit board 33 is fixedly mounted within the insulating inner shell 303, and the reactor 34 is mounted on the fireproof outer shell 304. This ensures effective insulation of the circuit board 33, thereby improving the safety of the circuit board 33, while the reactor 34 is mounted on the fireproof outer shell 304, which can improve the stability of the reactor 34.

[0234] This is because, generally, the mass of the reactor 34 is relatively large. By directly installing the reactor 34 on the fireproof housing 304, the stability of the reactor 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 that generate a lot of heat, so that the heat can be quickly dissipated to avoid malfunction caused by overheating of the circuit board 33.

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

[0237] Alternatively, as Figures 16 to 26The heat sink 35 includes a base plate 351 and heat dissipating fins 352. The base plate 351 is connected to at least some of the electronic components 331 on the circuit board 33 and is suitable for heat transfer. The base plate 351 is located within the housing 31. The heat dissipating fins 352 are connected to the base plate 351 and extend out of the housing 31 through the clearance opening 3058. During operation, some of the heat generated by the circuit board 33 is transferred to the base plate 351. The heat from the base plate 351 is then transferred to the heat dissipating fins 352. The heat dissipating fins 352 dissipate heat from the corresponding electronic components 331 on the circuit board 33 by exchanging heat with the medium outside the electrical control box 3.

[0238] In the present invention, the chassis 1 and the heat dissipation fins 352 of the radiator 35 can be formed integrally, 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 seal 353. The seal 353 surrounds the heat dissipating fins 352 and is positioned between the bottom plate 351 and the periphery of the clearance opening 3058 to form a sealed structure. The seal 353 prevents water from entering the electrical control box 3, thereby preventing safety hazards.

[0240] Alternatively, as Figures 16 to 26 The surface of the seal 353 that abuts the periphery of the clearance opening 3058 is provided with a plurality of annular ribs 354. The annular ribs 354 are annular and extend along the circumference of the seal 353. The annular ribs 354 are arranged in a plurality of rings spaced apart from each other from the inside out. Thus, the annular ribs 354 form a multi-layered sealing structure with the periphery of the clearance opening 3058, further improving the sealing effect.

[0241] Optionally, the cross section of the annular rib 354 is configured as a semicircle, a trapezoid or a rectangle;

[0242] In addition, the groove between two adjacent annular ribs 354 can be configured as a semicircular, trapezoidal, or rectangular shape. The second inner shell 312 and the seal 353 are designed to be pressed together, and a multi-rib compression seal is designed to prevent external water from entering the electric control box 3.

[0243] In addition, in the present invention, the radiator is arranged on the box seat, the box cover is covered on the box seat, the radiator extends from the box cover, and the box cover and the box seat are connected by fixing members at positions adjacent to both ends of the radiator.

[0244] Alternatively, as Figures 16 to 26The seal 353 includes a first portion 355 and a second portion 356. The first portion 355 covers the periphery of the surface of the bottom plate 351 connected to the heat dissipation fins 352, and the second portion 356 is sleeved on the periphery of the bottom plate 351. The first portion 355 and the second portion 356 cooperate to stably mount the seal 353 on the bottom plate 351, effectively improving the stability of the fit between the seal 353 and the bottom plate 351, thereby improving the sealing performance between the seal 353 and the box body 31.

[0245] Optionally, the surface of the heat dissipation fin 352 is configured in a corrugated shape, thereby increasing the surface area of ​​the heat dissipation fin 352 , thereby increasing the heat dissipation effect of the heat dissipation fin 352 and improving the heat dissipation effect on the electric control box 3 .

[0246] In addition, combined Figures 16 to 26 At least some of the electronic components 331 on the circuit board 33 are provided with a heat conducting sheet 358 , which transfers heat to the electronic components 331 , and the heat sink 35 and the heat conducting sheet 358 cooperate with each other and are suitable for heat conduction.

[0247] A gap in the range of 0.1 mm to 1 mm may be provided between the heat sink 35 and the heat conducting sheet 358 , and the gap may be filled with a heat conducting medium to improve the heat dissipation effect.

[0248] Optionally, a heat dissipation bracket 357 can also be set on the circuit board 33. During the installation process, the radiator 35 is installed on the heat dissipation bracket 357, and a heat conductive medium is filled between the radiator 35 and the heat conductive plate 358, and heat is conducted between the heat conductive plate 358 and the radiator 35 through the heat conductive medium.

[0249] In addition, a heat conducting sheet 358 can be installed on the heat dissipation bracket 357. The heat conducting sheet 358 is designed to be installed on the circuit board 33. The heat from the heating components on the circuit board 33 is transferred to the heat conducting sheet 358 through the heat conducting pins. The heat is then 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. Finally, the heat sink 35 transfers the excess heat outside the electric control box 3.

[0250] In conjunction with the aforementioned embodiment, the electrical control box 3 houses a circuit board 33, which is equipped with electronic components 331. Some of these components 331 generate significant heat and require heat dissipation via a heat sink 35. The heat sink 35 works in conjunction with the electronic components 331 to dissipate heat. A gap exists between the heat sink 35 and the corresponding electronic component 331, which can be filled with a heat transfer medium (e.g., silicone). A reactor 34 is located at the bottom of the electrical control box 3, separate from the circuit board 33. A partition wall 3018 can be provided between the reactor 34 and the circuit board 33. A forward-extending mounting portion 302 is provided at the bottom of the first outer shell 313. A mounting portion 302 is also provided at the bottom of the second inner shell 312, extending beyond the rear side of the second inner shell 312 or second outer shell 314 (or the box body 31). Both mounting portions 302 are connected to the chassis 1 via fasteners. Furthermore, as can be seen in the accompanying drawings, the heat sink 35 extends beyond the electrical control box 3.

[0251] In addition, if Figures 16 to 26 The upper portion of the right side of the second housing 314 is recessed to accommodate the protruding portion of the radiator 35. The second housing 314 is provided with a reinforcing rib 3046, which spans the recess and other portions of the second housing 314. Furthermore, the provision of the recessed structure 307 on the second housing 314 creates an opening at its lower end, which cannot be closed by sheet metal forming. A patching block 32 can be provided to seal the cover. The patching block 32 maintains the integrity of the electrical control box 3, effectively protecting the interior space of the box body 31 and ensuring stable operation. A portion of the edge of the cover 321 is provided with an upwardly extending first flange 322, which connects to the peripheral wall of the recessed structure 307. A portion of the edge of the cover 321 extends downward to form a second flange 323, which connects to the peripheral wall of the raised structure.

[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 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 above-mentioned embodiment, the circuit board 33 is installed on the inner side of the box base 305, and the heat sink 35 is installed on the circuit board 33. When the box cover 306 is closed on the box base 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 the positioning box cover 306 and the box base 305. In this way, the connection between the box cover 306 and the box base 305 can be facilitated, and the sealing part 353 between the radiator 35 and the box cover 306 can be ensured to be clamped, thereby improving the sealing between the radiator 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 base 305, and a clearance opening 3058 is provided on the box cover 306. The heat sink 35 extends out from the clearance opening 3058. A seal 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 vertical sides of the heat sink 35. One of the fixing members connects 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 (first flange 322), the second outer shell 314, the second inner shell 312, and the first inner shell 311 together.

[0255] Alternatively, as Figure 27 At least one of the first inner shell 311 and the second inner shell 312 is provided with a heat dissipation window 3023. The heat dissipation window 3023 facilitates heat exchange between the interior of the electrical control box 3 and the exterior of the electrical control box 3. Specifically, during use, heat from within the electrical control box 3 is discharged through the heat dissipation window 3023 to the fireproof outer shell 304, which is typically supported by a metal material. This allows heat to be easily exchanged with the external medium of the box body 31 after being transferred to the fireproof outer shell 304, thereby improving the heat dissipation efficiency of the electrical control box 3.

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

[0257] Alternatively, as Figure 27 The heat dissipation window 3023 is connected with support ribs 3024, which are arranged in a grid pattern 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 housing 313 . Maintaining a safe distance between the circuit board 33 and the first housing 313 can effectively improve the safety of the electric control box 3 .

[0260] The circuit board 33 generates heat during operation. Heat from certain heating components can cause excessive temperature rise inside the electrical control box 3, potentially damaging other electrical components. To address this heat dissipation issue, the back of the electrical control box 3 is hollowed out. This allows the heat in the hollowed-out area to directly contact the outer sheet metal (first housing 313), dissipating the internal heat outside the electrical control box 3. To ensure a safe distance between the sheet metal and electrical components, a gap D of 8 to 18 mm is established between the circuit board 33 and the second housing 314. This facilitates heat dissipation and is also considered safe for safety regulations.

[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 between the radiator 35 and the circuit board 33 is that a seal 353 is arranged around the radiator 35; the structure and arrangement of the heat dissipation fins 352 in the radiator 35 are such that 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 by snapping, and the structure and shape of the plastic inner shell are such that the inductor 34 ... inner shell is above the inductor 34

[0262] In some embodiments of the present invention, the electrical control box 3 comprises an insulating inner shell 303 and a fireproof outer shell 304. Therefore, water may enter between the insulating outer shell and the fireproof inner shell. Therefore, it is necessary to guide water in the insulating outer shell and the fireproof inner shell away from the interior space of the electrical control box 3. To this end, in some embodiments of the present invention, a drainage structure is provided for drainage. The body 31 of the electrical control box 3 may adopt the 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 has a first end (refer to the upper end of the box body 31 in the accompanying drawings) and a second end (refer to the lower end of the box body 31 in the accompanying drawings) that are 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, ensuring 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. Even if the electric control box 3 malfunctions and burns, 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 provided 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. In this case, the water between the insulating inner shell 303 and the fireproof outer shell 304 may penetrate into the electrical control box 3, causing the electrical control box 3 to malfunction. Therefore, the drainage groove 3049 is provided in the present invention. Through the drainage groove 3049, the water between the insulating inner shell 303 and the insulating outer shell is drained to a predetermined location for discharge, thereby ensuring the stable operation of the electrical control box 3. The drainage groove 3049 extends to the first end of the box body.

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

[0266] In order to achieve the connection between the electrical control box 3 and the shell of the outer box 22, the outer box 22 and the top of the fireproof outer shell 304 can be connected by fixings. 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 fixings.

[0267] Optionally, a positioning hole 3070 is provided in the fireproof outer shell 304 at the first end of the box body, and one end of the drainage groove 3049 extends to the first end and is vertically opposite the positioning hole 3070. As previously described, water may enter between the fireproof outer shell 304 and the insulating inner shell 303 through the positioning hole 3070. In this case, since one end of the drainage groove 3049 is opposite the positioning hole 3070, the water will flow under the drainage effect of the drainage groove 3049, thereby draining the water that has entered between the fireproof inner shell and the insulating outer shell to an appropriate location.

[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 that are spliced ​​together along the longitudinal direction, and a drainage groove 3049 extending vertically 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 a protruding structure 3071 that protrudes vertically away from the second inner shell 312, and the positioning hole 3070 is provided on the protruding structure 3071. In other words, at the first end of the box body 31, the fireproof outer shell 304 is provided with a protruding structure 3071, and the positioning hole 3070 is provided on the protruding structure 3071. The protruding structure 3071 can reduce the amount of water that can enter between the inner and outer shells through the positioning hole 3070, 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 defined 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 rib 3047 that protrudes vertically away from the interior space of the box body 31. The rib 3047 is located at the first end of the box body 31 and protrudes vertically from the edge of the second outer shell 314. The rib 3047 can block media such as water, keeping it outside the second outer shell 314 and preventing it from flowing into the mating position between the first inner shell 311 and the second inner shell 312, effectively providing waterproofing.

[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 water or other media does not flow into the junction of 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 longitudinally away from the first inner shell 311. 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, preventing it from flowing into the mating 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 relief groove 3050. The bottom surface of the relief groove 3050 is spaced apart from the second outer shell 314, and the relief groove 3050 is vertically opposed to the positioning hole 3070. The provision of the relief groove 3050 prevents the fixings from contacting the second inner shell 312 when the window air conditioner 1000 housing and the box body 31 are connected via fixings, thereby protecting the second inner shell 312 from damage and improving the waterproof performance of the electrical control box 3. Furthermore, the relief groove 3050 forms the entrance to the drainage groove 3049, allowing water that has entered between the fireproof outer shell 304 and the insulating inner shell 303 to be drained as quickly 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, the ribs 3051 extending vertically and longitudinally, and the plurality of ribs 3051 are arranged at intervals along 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. The ribs 3051 are spaced apart in the transverse direction (i.e., the left-right direction in the figure) and extend in the longitudinal direction (i.e., the front-back direction in the figure). Thus, a groove is formed between two adjacent ribs 3051 to receive water entering through the positioning holes 3070, facilitating the drainage of water entering between the inner and outer shells.

[0278] In addition, drainage grooves 3049 are 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. Forming drainage grooves 3049 on a plastic part is often easier than forming drainage grooves 3049 on a sheet metal part. Therefore, by providing drainage grooves 3049 on the insulating inner shell 303, the present invention can effectively simplify the production process.

[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 remain stable.

[0281] Optionally, the top wall of the housing assembly 2 is provided with a concave structure 205, and the first end of the electrical control box 3 is provided with a convex structure 3071. The concave structure 205 and the convex structure 3071 are connected by a fixing. The concave structure 205 of the housing assembly 2 cooperates with the convex structure 3071 of the electrical control box 3 to facilitate the fixing of the housing assembly 2 and the electrical control box 3. Furthermore, the concave structure 205 can accommodate the head of a screw, ensuring a smooth outer surface of the housing assembly 2.

[0282] The recessed structure 205 prevents the screw heads from protruding from the outer case surface. The recessed area for the screws is designed to prevent rainwater from accumulating. Therefore, drainage grooves 3049 are designed for the screw connections to prevent water droplets from seeping through the screw holes and accumulating on the electrical control box 3. Instead, water drips down the drainage grooves 3049 into the chassis 1 for secondary use (the condensed water in the chassis 1 is pumped through the axial fan 225 to cool the condenser, improving product performance and energy efficiency).

[0283] The electric control box 3 is installed vertically on the side of the outdoor air duct. To avoid large shaking, a screw is used to connect and fix the top of the electric control box 3 to the outer box. 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.

[0284] Optionally, in the window air conditioner 1000 having the electric control box 3, the outer box body 22 includes an outer box shell 221, the electric control box 3 is disposed in the outer box shell 221, and the electric control box 3 and the outer box shell 221 are connected by a fixing member. Optionally, the fixing member cooperates with the aforementioned positioning hole 3070.

[0285] Optionally, a louver is provided on the side of the box assembly 2 facing away from the chassis 1, and the louver is opposite to the second outer shell. At the first end of the box body, the edge of the second inner shell is provided with a convex rib that protrudes vertically in the direction away from the internal space of the box body. The convex rib protrudes vertically from the edge of the second outer shell. The louver is provided with a flange rib around the periphery, and the spacing between the flange rib and the 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 opposed to the second housing 314, or in other words, vertically offset from the first housing 313. When water enters the outer housing 22 through the louver, it splashes onto the second housing 314. Water from outside the louver flows only down to the top portion of the cover of the sheet metal electrical control box 3, flowing along the outer surface of the sheet metal electrical control box 3 into the chassis 1. Furthermore, the louver is provided with a flange rib 207 extending into the outer housing 22. The spacing L2 between the flange rib 207 and the aforementioned rib 3047 is no less than 6 mm. This facilitates the drainage of water from the top of the electrical control box 3, preventing it from entering the electrical control box 3 and affecting product quality.

[0287] Optionally, the sidewalls of the insulating inner shell 303 are provided with through-holes 3059, which are inclined toward the second end from the inside out. This allows heat from within the insulating inner shell 303 to dissipate through the holes 3059. Because the fireproof outer shell 304 protects the insulating inner shell 303, external water, steam, etc., cannot enter the box body 31 through the holes 3059. Heat can be dissipated through the fireproof outer shell 304, thereby achieving waterproof, fireproof, and heat dissipation properties.

[0288] Optionally, at least a portion of the peripheral wall of the heat dissipation hole 3059 extends beyond the outer side of the insulating inner shell 303. The extension of the peripheral wall of the heat dissipation hole 3059 can separate the insulating inner shell 303 from the insulating outer shell, thereby providing an airflow channel between the inner and outer shells for airflow, further improving the heat dissipation effect of the electric control box 3.

[0289] Optionally, the peripheral walls of the heat dissipation holes 3059 extend beyond the side surfaces of the insulating inner housing 303. The side walls of the heat dissipation holes 3059 protruding from the first end extend longer than the side walls of the heat dissipation holes 3059 protruding from the second end. Furthermore, the edges of the side walls of the heat dissipation holes 3059 proximate the first end are provided with notches 3060. This prevents the heat dissipation holes 3059 from being blocked by the fireproof outer housing 304, allowing hot air from within the insulating inner housing 303 to escape through the heat dissipation holes 3059 and improving heat dissipation. Furthermore, the notches 3060 provided in the heat dissipation holes 3059 facilitate overall airflow within the electrical control box 3.

[0290] As mentioned above, in order to assist in the internal heat dissipation of the electric control box 3, the present invention is designed with a downwardly oblique 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 is dissipated, reducing the internal temperature of the electric control box 3, which is beneficial to extending the life of the electrical components; the side wall is designed with a downwardly oblique 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 oblique hole to avoid flowing into the electric control box 3.

[0291] Optionally, in combination with the aforementioned embodiment, the insulating inner shell 303 includes a first inner shell 311 and a second inner shell 312 that are joined together, both of which are arranged vertically. The joining of the first inner shell 311 and the second inner shell 312 facilitates the molding of the insulating inner shell 303, facilitating the installation of electronic components 331, circuit boards 33, and the like within the electrical control box 3, thereby improving assembly efficiency and facilitating maintenance of the electrical control box 3. The fireproof outer shell 304 includes a first outer shell 313 and a second outer shell 314. The first outer shell 313 is positioned outside the first inner shell 311, and the second outer shell 314 is positioned outside the second inner shell 312. This effectively prevents fires, improves the safety of the air conditioner, and facilitates maintenance of the electrical control box 3. The first outer shell 313 has a positioning hole 3070 at its first end. The end surface of the first inner shell 311 at the first end is configured to tilt toward the second end, away from the second inner shell 312. The structure of the box body 31 is simplified, and the water entering the inner side of the first shell 313 through the positioning hole 3070 is conveniently guided to avoid damaging the electric control box 3 .

[0292] Optionally, in combination with the above embodiment, at the second end of the box body 31, the second inner shell 312 is provided with a connecting portion 3043 for connecting to the chassis 1, and the connecting portion 3043 is provided with a threaded hole, which is a blind hole. It is further characterized in that the connecting portion 3043 has a hole.

[0293] Optionally, an air guide notch 3052 is provided in the insulating inner shell 303 at the second end of the box body 31. The air guide notch 3052 extends through the interior and exterior of the insulating inner shell 303 and forms a circuitous flow path within the air guide notch 3052. The air guide notch 3052 allows air to flow through it, thereby dissipating heat from the interior of the electrical control box 3, improving heat dissipation efficiency and effectiveness. This effectively maintains the operating environment of the electrical control box 3 and reduces the risk of failure.

[0294] Optionally, at the second end of the box body 31, the insulating inner shell 303 is provided with a first baffle 3061, a second baffle 3062, and a third baffle 3063. The first baffle 3061 and the second baffle 3062 are provided with vertically opposed vents, and the third baffle 3063 is spaced between the three vents of the first baffle 3061 and the second baffle 3062. The first baffle 3061, the second baffle 3062, and the third baffle 3063 form a circuitous flow path, resulting in a simple structure and easy molding. The labyrinth rib design of the outlet 3013 facilitates heat dissipation from the electrical control box 3 while preventing external water from entering the electrical control box 3.

[0295] In addition, by providing a circuitous flow channel, the heat dissipation efficiency can be improved while effectively preventing liquids from entering the interior of the electric control box 3 , thereby improving the waterproof performance of the electric control box 3 .

[0296] Optionally, a wire outlet notch 3025 is provided at the second end of the box body 31. The notch 3025 extends through the interior and exterior spaces of the insulating inner shell 303. Outwardly protruding drainage ribs 3026 are provided around the periphery of the notch 3025. The notch 3025 facilitates the extraction of wires from the box body 31, while the drainage ribs 3026 facilitate water drainage. The drainage ribs 3026 direct liquid away from the wire outlet 3013, preventing liquid from entering the notch 3025 and being sucked into the box body 31 by siphoning. This further enhances the waterproof performance of the electrical control box 3.

[0297] Optionally, in combination with the above embodiment, one of the first inner shell 311 and the second inner shell 312 is provided with a wire outlet notch 3025 and the other is provided with a wind guide notch 3052 , and the wire outlet notch 3025 and the wind guide notch are opposite to each other in the longitudinal direction.

[0298] When the electric control box 3 is applied to the aforementioned window air conditioner 1000, the application of the electric control box 3 can 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, thereby facilitating the modular design, production, installation and maintenance of the window air conditioner 1000.

[0299] The electric control box 3 of the present invention is an electric control component. It needs to transmit signals with the controlled components and also needs to receive external control signals and feedback signals. Therefore, signal transmission can be performed wirelessly or wired. When signal transmission and energy transmission are performed through wired signals, the wiring harness needs to be positioned.

[0300] Therefore, if Figures 31 to 34 According to an embodiment of the present invention, the electric control box 3 includes: a box body 31, a circuit board 33 and a radiator 35. A wiring groove 3027 is provided in the box body 31. The wiring groove 3027 has a wire outlet 3013. The wiring harness can be positioned in the wiring groove 3027 and guided along the wiring groove 3027 to the wire outlet 3013 for connecting to other controlled or controlling devices. The circuit board 33 is provided in the box body 31. The circuit board 33 has electronic components 331. The radiator 35 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 radiator 35 can be used to dissipate heat from the circuit board 33, especially for components on the circuit board 33 that consume a lot of energy and generate a lot of heat, thereby maintaining stable operation of the circuit board 33 and reducing the failure rate.

[0301] According to the electric control box 3 of the embodiment of the present invention, a wiring groove 3027 is provided to guide the wire harness, which facilitates the arrangement and positioning of the wire harness. The heat sink 35 can improve the heat dissipation effect of the circuit board 33 and facilitate the heat dissipation of the circuit board 33.
