In some embodiments of the present invention, the electric control box 3 can also be installed on the chassis 1. The electric control box 3 and the chassis 1 can be plugged in and positioned on the chassis 1 by fixing members. For example, after the electric control box 3 and the chassis 1 are plugged in, pre-positioning of the electric control box 3 and the chassis 1 is achieved, and then the electric control box 3 and the chassis 1 are fixedly connected together by fixing members.

[0117] For the window air conditioner 1000 according to the embodiments of the present invention, the electric control box 3 is positioned on the chassis 1 through the combination of plugging and fixing members, which can improve the stability of the electric control box 3, that is, the chassis 1 provides a stable supporting effect on the electric control box 3. Through plugging and positioning by fixing members, rapid installation of the electric control box 3 can be achieved. Moreover, plugging can play a certain pre-positioning role, and through the pre-positioning of plugging, rapid positioning of the electric control box 3 and the chassis 1 by fixing members can be realized.

[0118] Combined with the foregoing embodiments, the electric control box 3 is provided in the outer box shell 221, and the electric control box 3 is provided inside the rear enclosure panel 227 or the outdoor air duct assembly 223 (i.e., the side close to the inner box body 21).

[0119] In the present invention, one side of the bottom of the electric control box 3 is plugged into the chassis 1 through a plug pin 301, and the other side is connected to the chassis 1 by fixing members such as screws. The bottom of the plastic inner shell of the electric control box 3 has a plug pin 301 near the compressor 229 side, and the chassis 1 has a socket 101 corresponding to the plug pin 301.

[0120] Optionally, as Figures 7 to 10 , the chassis 1 is provided with a socket 101, and the socket can be set to be open along the transverse direction (the left - right direction in the accompanying drawings). One end of the bottom of the electric control box 3 along the transverse direction is provided with a plug pin 301, and the plug pin 301 is plugged into the socket 101 along the transverse direction, and the transverse direction is parallel to the chassis 1. Through the cooperation of the socket 101 and the plug pin 301 parallel to the chassis 1, the plug pin 301 can be quickly plugged into the chassis 1, and it is convenient to connect the electric control box 3 and the chassis 1 through fixing members.

[0121] Certainly, the socket 101 of the present invention can also be set in a form perpendicular to the chassis 1. At this time, the plug pin 301 on the electric control box 3 can be set in a hook shape, that is, the plug pin 301 is inserted into the socket 101 and hooks the chassis 1 to complete the plugging and positioning of the electric control box 3 and the chassis 1. The present invention mainly takes the socket 101 along the transverse direction as an example for description, but it is not a limitation on the protection scope of the present invention.

[0122] In addition, the electric control box 3 in the present invention can also complete the plugging and cooperation with the chassis 1 through plugging along the longitudinal direction (the front - rear direction in the accompanying drawings).

[0123] It should be noted that in the present invention, the horizontal direction can be the left - right direction in the figure, the longitudinal direction can be the front - back direction in the figure, and the vertical direction can be the up - down direction in the figure.

[0124] Optionally, as Figures 7 to 10 , a part of the chassis bulges to form a socket. Specifically, referring to the attached drawings, a part of the chassis bulges upward to form a socket, and the edge of the top wall of the socket extends obliquely to construct a flared shape. Specifically, the edge of the top wall of the socket 101 is set to extend upward obliquely, so that the opening of the socket 101 is set in a flared form. During the process of the plug pin 301 being inserted into the socket 101, the plug pin 301 can quickly cooperate with the socket 101, facilitating the quick cooperation between the plug pin 301 and the socket 101 and improving the assembly efficiency.

[0125] Optionally, as Figures 7 to 10 , the side wall edge of the socket 101 is provided with a notch 102. As shown in the figure, the front and rear side walls of the socket 101 are provided with notches 102. In this way, a larger flared shape will be formed at the opening of the socket 101, further facilitating the cooperation between the plug pin 301 and the socket 101, enabling the plug pin 301 to be quickly inserted into the socket 101 and realizing the quick positioning of the plug pin 301 and the socket 101.

[0126] Optionally, as Figures 7 to 10 , a relief notch 309 is provided at the position of the electric control box 3 opposite to the socket 101. The relief notch 309 can provide a relief structure, for example, relieving the socket 101, relieving the wiring structure, etc. At the same time, it can provide a larger installation space and is convenient for observation. The relief notch 309 has a first surface and a second surface. The first surface is opposite to the socket 101 along the direction perpendicular to the chassis 1 (i.e., the vertical direction, or the up - down direction in the figure), and the second surface is opposite to the socket 101 along the horizontal direction. A connecting portion 3043 is provided at the relief notch 309. The connecting portion 3043 is connected to the first surface and the second surface respectively, and the plug pin 301 is connected to the connecting portion 3043. That is, the plug pin 301 structure is arranged at the relief notch 309, which can facilitate the quick cooperation between the plug pin 301 and the socket 101. Moreover, through the connection of the connecting portion 3043, the structural strength at the relief notch 309 can be improved. Also, the overall structure of the electric control box 3 is simplified.

[0127] Optionally, 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 towards the socket 101 (downward in the figure), and the plug pin 301 is connected to the free end of the first connecting rod 3044. This facilitates the insertion and cooperation between the plug pin 301 and the socket 101. Moreover, by providing the relief notch 309, a larger visual space can be obtained, facilitating the insertion operation.

[0128] In addition, as Figures 7 to 10 , the connecting portion 3043 further includes a second link 3045. The second link 3045 is connected to the second surface, and the second link 3045 extends toward the socket 101 and is connected to the first link 3044. The connection between the second link 3045 and the first link 3044 can effectively improve the structural strength of the first link 3044, that is, effectively improve the structural strength of the bolt 301, and improve the positioning stability of the bolt 301 and the chassis 1.

[0129] In addition, as Figures 7 to 10 , the connecting portion 3043 further includes a reinforcing rib 3046. The reinforcing rib 3046 is connected between the first surface, the second surface, the first link 3044, and the second link 3045. By providing the reinforcing rib 3046, the structural strength of the connecting portion 3043 and the electric control box 3 can be effectively improved, and at the same time, the structural strength of the bolt 301 is also improved.

[0130] In addition, the reinforcing rib 3046 in the present invention is an annular hollow structure, a U-shaped structure, a T-shaped structure, etc. Through the structure of the reinforcing rib 3046, an air flow channel can be formed on the connecting portion 3043, so that air flow can pass through to enhance the heat dissipation of the electric control box 3.

[0131] In addition, an outlet 3013 can be provided at the relief notch 309, and a wire harness or the like can be led out from the outlet 3013. Through the shape setting of the reinforcing rib 3046, wiring can be facilitated. For example, the reinforcing rib 3046 is set in a U-shaped shape extending along the first link 3044, the second link 3045, and the second surface.

[0132] Optionally, as Figures 1 to 10 , a first convex hull 11 is provided on the chassis 1, and the socket 101 is provided on the top wall of the first convex hull 11. In this way, after the bolt 301 is inserted into the socket 101, there will be a certain space between the bolt 301 and the bottom surface of the chassis 1, and the bolt 301 will not protrude from the bottom surface of the chassis 1, so as to ensure that the chassis 1 can be stably supported on other devices or structures. In addition, by providing the first convex hull 11, it is possible to prevent water or the like from entering the electric control box 3 under the action of siphon or the like.

[0133] Optionally, as Figures 7 to 10 , an installation portion 302 is provided at the other end of the bottom of the electric control box 3 along the transverse direction. The installation portion 302 and the chassis 1 are connected by a fixing member, and the transverse direction is parallel to the chassis 1. It is convenient for the fixing member to connect the installation portion 302 and the chassis 1.

[0134] Optionally, as Figures 7 to 10, on both opposite longitudinal sides of the upper edge of the electric control box 3, there are installation parts 302 extending longitudinally. That is, the installation parts 302 are led out from the front and rear sides of the electric control box 3. In this way, it is convenient to connect the installation parts 302 and the chassis 1 through fixing parts, effectively improving the connection efficiency between the electric control box 3 and the chassis 1.

[0135] In addition, multiple fixing parts on the installation parts 302 on both sides of the electric control box 3 are arranged in a triangular pattern. By using the fixing parts arranged in a triangular pattern, a stable positioning structure 3019 can be formed, facilitating the stable connection between the electric control box 3 and the chassis 1.

[0136] Of course, setting the fixing parts in a triangular pattern in the present invention is only one embodiment of the present invention. The fixing parts connecting the electric control box 3 and the chassis 1 in the present invention can also be set in a quadrilateral or other polygonal shapes, or even only one or two fixing parts are provided. Due to the cooperation of the insertion and the fixing parts, the quick positioning between the electric control box 3 and the chassis 1 can also be achieved.

[0137] Optionally, as Figures 7 to 10 , there is a second convex hull 12 on the chassis 1, and the installation part 302 is connected to the second convex hull 12. Through the second convex hull 12, the electric control box 3 can be supported, preventing condensed water on the chassis 1 from entering the interior of the electric control box 3. Moreover, it is also convenient for the installation of the electric control box 3, avoiding the formation of a raised structure by the fixing parts on the bottom surface of the chassis 1, effectively improving the stability of the cooperation between the electric control box 3 and the chassis 1, and facilitating the installation of the chassis 1 on other devices or structures.

[0138] Optionally, there is a groove (not shown in the figure) on the second convex hull 12 that faces the electric control box 3 and is recessed away from the electric control box 3. The cooperation area between the electric control box 3 and the chassis 1 can be reduced, thus facilitating the stable cooperation between the electric control box 3 and the chassis 1, and facilitating the flow of air through the space between the electric control box 3 and the chassis 1, avoiding heat accumulation and facilitating heat dissipation.

[0139] Optionally, in the present invention, the aforementioned first convex hull 11 is higher than the second convex hull 12. That is to say, the insertion structure of the electric control box 3 and the connection structure of the fixing parts are located on different planes, thus 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.

[0140] Optionally, as Figure 8, the cabinet assembly 2 includes a compressor 229, and the compressor 229 is used to provide the power for the flow of the heat exchange refrigerant. The electric control box 3 is disposed adjacent to the compressor 229, that is to say, the electric control box 3 is disposed on a part of the outer cabinet 22. The bottom of the electric control box 3 is adjacent to the end of the compressor 229 and is inserted into the chassis 1, and the end of the bottom of the electric control box 3 away from the compressor 229 is positioned with the chassis 1 by a fixing member. Due to the setting of the compressor 229, the installation space at the end of the electric control box 3 adjacent to the compressor 229 is relatively small, and it is not suitable to connect the electric control box 3 and the chassis 1 through a fixing member. The insertion structure has relatively low requirements for the installation space. Therefore, setting the electric control box 3 to be inserted at the end close to the compressor 229 and connected by a fixing member at the end away from the compressor 229 can improve the matching efficiency between the electric control box 3 and the chassis 1 and facilitate the installation of the electric control box 3 on the chassis 1.

[0141] Figure 8 is a schematic diagram of the positional relationship among the chassis 1, the outdoor air duct assembly 223, the electric control box 3, and the compressor 229 in the window air conditioner 1000 according to an embodiment of the present invention. Among them, the outdoor air duct assembly 223, the electric control box 3, and the compressor 229 are all installed on the chassis 1 and are located at the rear end of the chassis 1, and the electric control box 3 is located in front of the outdoor air duct assembly 223. An opening is provided at the front end of the chassis 1 for ventilation. The end of the electric control box 3 adjacent to the compressor 229 is inserted into the chassis 1, and the end of the electric control box 3 away from the compressor 229 is fixedly connected to the chassis 1 by a fixing member (such as a screw). The chassis 1 is provided with a first convex bump 11 and a second convex bump 12, and the electric control box 3 is inserted into the first convex bump 11 and connected to the second convex bump 12 by a fixing member.

[0142] Optionally, the electric control box 3 stands upright on the chassis 1. This facilitates the heat dissipation of the electric control box 3, and moreover, it can also reduce the space occupied by the electric control box 3 and improve the space utilization rate.

[0143] Next, the structure of the electric control box 3 in the present invention will be described with reference to the drawings. The electric control box 3 can be applied to the window air conditioner 1000 of any other embodiment of the present invention, and can also be applied to other air conditioners, fresh air fans, kitchen appliances and other devices.

[0144] As Figure 7 shown, according to the electric control box 3 of the embodiment of the present invention, the electric control box 3 includes a box body 31, and the box body 31 includes: an insulating inner shell 303 and a fireproof outer shell 304. The insulating inner shell 303 has a cavity inside; the fireproof outer shell 304 covers the outside of the insulating inner shell 303. Through the insulating inner shell 303, the effective insulation between the circuit board 33 and the electric control box 3 can be ensured, and the safety of the electric control box 3 can be ensured. The fireproof outer shell 304 can effectively improve the fireproof performance of the electric control box 3. Even if the electric control box 3 fails and catches fire, it will not damage the rest of the air conditioner or even cause a fire.

[0145] Among them, the insulating inner shell 303 in the present invention can be a plastic inner shell, and the fireproof outer shell 304 can be a metal outer shell.

[0146] Optionally, as Figures 7 to 15 , the insulating inner shell 303 includes a first inner shell 311 and a second inner shell 312 that are joined together. Among them, the first inner shell 311 and the second inner shell 312 are joined together longitudinally. Through the joining of the first inner shell 311 and the second inner shell 312, the molding of the insulating inner shell 303 can be facilitated, which is convenient for the installation of the electronic components 331, circuit boards 33, etc. inside the electric control box 3, improving the assembly efficiency of the electric control box 3 and facilitating maintenance.

[0147] Among them, the joining of the first inner shell 311 and the second inner shell 312 means that a relatively enclosed space is formed by the first inner shell 311 and the second inner shell 312.

[0148] Optionally, 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 covers the outside of the first inner shell 311, and the second outer shell 314 covers the outside of 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.

[0149] Optionally, in combination with the foregoing embodiments, the first inner shell 311, the second inner shell 312, the first outer shell 313, and the first outer shell 313 are all erected on the chassis 1. The first inner shell 311 and the second inner shell 312 are joined together in a direction parallel to the chassis 1 (such as the aforementioned longitudinal direction). Thus, the installation of the electric control box 3 is further facilitated, and the assembly efficiency and stability of the electric control box 3 are improved.

[0150] Optionally, the first inner shell 311 can be made of plastic material. For example, the first inner shell 311 is an integrally injection-molded structure. In addition, the second inner shell 312 can also be made of plastic material and can also be formed into an integral structure by injection molding. The first outer shell 313 and the second outer shell 314 can be made of metal material, for example, by sheet metal forming. In other words, in an alternative embodiment of the present invention, the first outer shell 313 and the second outer shell 314 are integrally formed by sheet metal.

[0151] Optionally, the first inner shell 311 and the second inner shell 312 are connected by snap or screw. The first outer shell 313 and the first outer shell 313 are connected by snap or screw. Thus, a stable connection structure is formed 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, improving the stability of the box body 31.

[0152] Specifically, a first snap structure 3014 is provided on the outer periphery of the first inner shell 311, and a second snap structure 3040 is provided on the outer periphery of the second inner shell 312.

Optionally, one of the first snap structure 3014 and the second snap structure 3040 can be a snap hook, and the other can be a snap projection 3069, so that the first inner shell 311 and the second inner shell 312 can be quickly and stably connected together through the snap structure.

[0153] Optionally, a first ear portion 3065 extends from the outer periphery of the first outer shell 313, and a second ear portion 3067 extends from the outer 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 first outer shell 313 and the second outer shell 314 can be stably connected together through the fixing member. In addition, since the first outer shell 313 covers the first inner shell 311 and the second outer shell 314 covers the second inner shell 312, the entire box body 31 structure can be stably assembled through the connection between the first outer shell 313 and the second outer shell 314.

[0154] Optionally, the first inner shell 311 and the first outer shell 313 are snap-connected or screw-connected. Specifically, a snap button can be provided on the outer side surface of the first inner shell 311, and a through hole is provided on the peripheral wall of the first outer shell 313. Through the cooperation of the snap button and the through hole, the snap connection between the first inner shell 311 and the first outer shell 313 can be realized. In addition, screw connection can be combined or used alone to connect the first inner shell 311 and the first outer shell 313.

[0155] Optionally, the second inner shell 312 and the second outer shell 314 are snap-connected or screw-connected. Specifically, a snap button can be provided on the outer side surface of the second inner shell 312, and a through hole is provided on the peripheral wall of the second outer shell 314. Through the cooperation of the snap button and the through hole, the snap connection between the second inner shell 312 and the second outer shell 314 can be realized. In addition, screw connection can be combined or used alone to connect the second inner shell 312 and the second outer shell 314.

[0156] In addition, the first inner shell 311 and the second inner shell 312 can also be connected by a fixing member, and the first outer shell 313 and the second outer shell 314 can also be snap-connected. Any one of the first inner shell 311 and the first outer shell 313, the second inner shell 312 and the second outer shell 314, and the first inner shell 311 and the second inner shell 312, the first outer shell 313 and the second outer shell 314 in the present invention can also be connected by a combination of a snap and a fixing member.

[0157] Among them, structures such as the aforementioned mounting portion 302 can be provided on the first outer shell 313 and the second inner shell 312 of the present invention. For example, the aforementioned bolt 301 is provided on the insulating inner shell 303 and protrudes from the fireproof outer shell 304, and the aforementioned connecting portion 3043 is also provided on the insulating inner shell 303 and protrudes from the fireproof outer shell 304, thereby facilitating the molding of the bolt 301 and the connecting portion 3043.

[0158] In addition, from another perspective, the box body 31 can be composed of a box base 305 and a box cover 306. Among them, the box base 305 can be composed of a first inner shell 311 and a first outer shell 313, and the box cover 306 can be composed of a second inner shell 312 and a second outer shell 314.

[0159] Optionally, in combination with the foregoing embodiments, a connecting portion 3043 is provided on the box body 31. Among them, the connecting portion 3043 can be provided on the second inner shell 312, and the connecting portion 3043 is not covered by the fireproof outer shell 304.

The mounting portion 302 is provided on the first outer shell 313, 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 the 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 members.

[0161] Figure 9 and Figure 10 are schematic diagrams of different orientations in the mating structure of the chassis 1 and the electric control box 3 in a window air conditioner according to an embodiment of the present invention. Figure 9-1 is Figure 9 a partial enlarged schematic diagram of the area of the circle D in Figure 10-1 is Figure 10 a partial enlarged schematic diagram of the area of the circle E in Figure 9 and Figure 10 As shown, a socket 101 is provided on the first convex hull. Among them, the socket 101 is configured in a flared form, and notches 102 are provided on the front and rear sides of the socket 101. A relief notch 309 is provided on the electric control box 3.

[0162] Figure 12 and Figure 13A schematic diagram showing the cooperation (i.e., the lid 306) of the second inner shell 312 and the second outer shell 314 of the electronic control box 3 in different orientations is shown. The aforementioned connecting portion 3043 and the support structure are both provided on the second inner shell 312, and the second outer shell 314 covers the outer shell of the second inner shell 312 without covering the connecting portion 3043 and the support structure. A relief opening 3058 is provided on the lid 306, and the radiator 35 cooperating with the circuit board 33 on the base 305 can pass through the relief opening 3058, thereby improving the heat dissipation effect on the circuit board 33.

[0163] The fireproof outer shell 304 is made of rust-proof sheet metal or surface-sprayed sheet metal, etc., to achieve rust prevention and fire prevention, and the product is safe and reliable.

[0164] 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 electronic control box 3 is locked to the chassis 1 by two screws, and the metal outer shell of the electronic control box 3 is locked to the chassis 1 by one screw, for a total of three screws.

[0165] In the present invention, a sealing structure is provided at the cooperation between the base 305 and the lid 306. In addition, the electronic control box 3 can be placed inside the outer box 22 on the inner side of the cooling fan.

[0166] 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. Through the sealing structure, the waterproof performance of the electronic control box 3 can be improved.

[0167] Such as Figure 16 and Figure 18 , a sealing groove 3015 facing the second inner shell 312 is provided on the peripheral wall of the first inner shell 311, and a sealing rib 3041 facing the first inner shell 311 is provided on the second inner shell 312. The sealing rib 3041 is embedded in the sealing groove 3015. Thus, a sealing structure is formed to achieve the sealing of the cooperation structure between the first inner shell 311 and the second inner shell 312.

[0168] 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.

[0169] 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 covers the outside of the first inner shell 311 and covers the first end plate and the first peripheral wall. The second outer shell 314 covers the outside of the second inner shell 312 and covers the second end plate and the second peripheral wall. The end face of the first peripheral wall is provided with the aforementioned sealing rib 3041, and the end face of the second peripheral wall is provided with the aforementioned sealing groove 3015. A sealing ring 3016 is arranged in the sealing groove 3015. The sealing rib 3041 is embedded into the sealing groove 3015 and presses the sealing ring 3016 to achieve sealing.

[0170] As Figure 16 and Figure 18 , a schematic diagram of the cooperation (i.e., the box seat 305) between the first inner shell 311 and the first outer shell 313 of the electric control box 3 in different orientations is shown. It can be seen that a sealing groove 3015 is provided on the periphery of the first inner shell 311, and a sealing ring 3016 can be arranged in the sealing groove 3015. The corresponding structure on the second inner shell 312 can be embedded into the sealing groove 3015 and press against the sealing ring 3016, thereby realizing the sealing of the electric control box 3, especially the fitting gaps at the upper part, left side part, and right side part of the electric control box 3.

[0171] In addition, in order to improve the sealing performance of the sealing structure, in the present invention, a fixing member connection is provided at a position adjacent to the sealing ring 3016. In this way, through the connection of the fixing member, it is convenient for the sealing rib 3041 to press against the sealing ring 3016 more tightly, or for the effective cooperation between the sealing rib 3041 and 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, as 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.

[0172] Optionally, as Figure 16 and Figure 18 , a first clamping groove 3042 with an opening facing the first inner shell 311 is provided on the inner side of the peripheral wall of the second inner shell 312. The peripheral wall of the first inner shell 311 is embedded into the first clamping groove 3042, and the sealing rib 3041 is arranged on the inner bottom surface of the first clamping groove 3042. Through the cooperation between the peripheral wall of the first inner shell 311 and the first clamping groove 3042, and the cooperation between the sealing rib 3041 and the sealing groove 3015, a tortuous joint surface can be formed at the joint of the first inner shell 311 and the second inner shell 312, thereby effectively preventing water and the like from entering the interior of the electric control box 3.

[0173] Optionally, a rib 3047 protruding in a direction away from the first inner shell 311 is provided at the edge of the peripheral wall of the second inner shell 312. Since the peripheral wall of the first inner shell 311 is embedded in the first card 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 can prevent the medium such as water from entering the joint between the first inner shell 311 and the second inner shell 312 through its blocking effect, further effectively improving the waterproof performance and the like between the first inner shell 311 and the second inner shell 312.

[0174] The first inner shell 311 and the second inner shell 312 are matched. To prevent external water from entering the electronic control, a double-slot and double-rib position cross-matching design is adopted, and a secondary sealing design with a rubber sealing strip is adopted in the middle; wherein, the first card slot 3042 is provided on the second inner shell 312 and is designed to match the rib on the outer edge of the first inner shell 311, and an outward draft design is adopted for the outer edge, which is beneficial to outward drainage. The sealing groove 3015 is designed on the first inner shell 311 and is matched with the convex part. The sealing strip is designed in the sealing groove 3015. Through the cooperation of the rib 3047 and the rubber sealing strip, a secondary sealing effect is achieved, and external water sources are prevented from entering the electronic control box 3.

[0175] Optionally, the rib 3047 protrudes from the inner peripheral surface or the outer peripheral surface of the second outer shell 314. In this way, when there is already a medium such as water on the second outer shell 314, the rib 3047 can also effectively block it and prevent the medium such as water from flowing to the joint between the first inner shell 311 and the second inner shell 312.

[0176] Optionally, a second card 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 card slot 3017. In this way, the assembly efficiency and the fireproof and waterproof performance can be improved.

[0177] Also, for example, as Figure 16 and Figure 18 , an I-shaped structure with sealing grooves 3015 and second card slots 3017 respectively provided on both longitudinal sides is provided on the top wall of the first inner shell 311.

[0178] Optionally, as Figure 16 and Figure 18 , a concave structure is provided on the outer surface of one end of the electronic control box along the vertical direction, and the other end of the electronic control box along the vertical direction is a convex structure protruding relative to the concave structure. A patch is provided at the step formed between the concave structure and the convex structure. In other words, a concave structure 307 is provided on the outer surface of the electronic control box 3. The electronic control box 3 is arranged vertically. The concave structure 307 is provided at one end of the electronic control box 3 along the vertical direction. The other end of the electronic control box 3 along the vertical direction is a convex structure protruding relative to the concave structure 307. A patch 32 is provided at the step formed between the concave structure 307 and the convex structure.

[0179] Specifically, a recessed structure 307 is provided on the outer surface of one end of the electric control box 3 along the vertical direction. Relatively speaking, there will be a protruding structure at the other end of the electric control box 3 along the vertical direction. That is to say, one end of the outer surface of the box body 31 forms a recessed structure 307 along the vertical direction while the other end forms a protruding structure.

[0180] Among them, as Figure 16 and Figure 18 , the said protruding structure and the recessed structure 307 are relative to each other. That is to say, the recessed structure 307 is a recess relative to the protruding structure, and the protruding structure is a protrusion relative to the recessed structure 307.

[0181] At this time, at the junction of the recessed structure 307 and the protruding structure (i.e., the said step), there will be a height difference. The height difference here can be closed by stretching the sheet metal through sheet metal forming, or it can be covered in other ways. For example, the height difference here can be closed by setting a patch block 32.

[0182] It should be noted that the box body 31 in the present invention includes an insulating inner shell 303 and a fireproof outer shell 304. The fireproof outer shell 304 generally adopts sheet metal forming. Taking the sheet metal forming into a cuboid structure as an example, a recessed structure 307 is formed by recessing a part of one side of the cuboid. There will be a height difference between the recessed structure 307 here and the non-recessed part. In this way, an opening will be formed at the junction of the recessed structure 307 and the non-recessed part. The opening can be closed through sheet metal processing. However, the cost of this sheet metal processing is relatively high. Therefore, a patch block 32 is provided in the present invention to close the opening. In addition, the patch block 32 is used to close the opening on the fireproof outer shell 304, and the insulating inner shell 303 can be injection molded without forming an opening. Therefore, after setting the sealing block, the relative integrity of the fireproof outer shell 304 can be ensured, thereby improving the fireproof performance of the electric control box 3.

[0183] In addition, the electric control box 3 in the present invention can be erected. The recessed structure 307 is provided on the upper part of the box body 31 while the protruding structure is provided on the lower part. When the electric control box 3 is placed outdoors, sunlight may shine on the electric control box 3, especially on the position where the patch block 32 of the electric control box 3 is located. When the patch block 32 is not provided, the sunlight irradiation will damage the electric control box 3 (insulating inner shell 303). Therefore, the patch block 32 can effectively protect the electric control box 3 and improve the operating stability of the electric control box 3.

[0184] Specifically, since the box body 31 includes an insulating inner shell 303 and a fireproof outer shell 304, and the opening formed by the aforementioned drop is formed on the fireproof outer shell 304, a part of the insulating inner shell 303 will be exposed. The insulating inner shell 303 is generally made of plastic parts, and the exposed part is easily damaged by sunlight. Therefore, by providing a sealing and patching block in the present invention, direct sunlight can be prevented from shining on the plastic parts, thereby effectively protecting the box body 31. In addition, in combination with Figure 16 and Figure 18 , one end of the convex structure facing the concave structure 307 is covered by the patching block 32. Through the patching block 32, the integrity of the electric control box 3 can be maintained, the internal space of the box body 31 can be effectively protected, and the stable operation of the electric control box 3 can be maintained. In addition, the patching block 32 also plays a role in fire prevention.

[0185] Optionally, a strengthening structure (such as a strengthening structure formed by stamping) is provided in and around the concave structure 307, and the strengthening structure can straddle the concave structure 307, the convex structure, and the areas near the concave structure 307 and the convex structure.

[0186] Optionally, as Figure 13 and Figure 18 , the patching block 32 includes: a cover plate 321, the cover plate 321 covers the step between the convex structure and the concave structure 307, a part of the peripheral edge of the cover plate 321 is provided with a first flanging 322 extending vertically towards the concave structure 307, the first flanging 322 is connected to the wall of the concave structure 307, and another part of the peripheral edge of the cover plate 321 is provided with a second flanging 323 extending vertically towards the convex structure, and the second flanging 323 is connected to the wall of the convex structure. Through the first flanging 322 and the second flanging 323, the patching block 32 can be stably connected to the box body 31.

[0187] Specifically, a part of the edge of the cover plate 321 is provided with a first flanging 322 extending upwards, the first flanging 322 is connected to the wall of the concave structure 307, a part of the edge of the cover plate 321 extends downwards to form a second flanging 323, and the second flanging 323 is connected to the wall of the convex structure.

[0188] Optionally, as Figures 13 to 18 , a part of the wall of the concave structure 307 bulges outwards of the electric control box 3 and constructs a vertical socket 3068, and an insertion buckle 324 extending vertically towards the cover plate 321 is formed on the first flanging 322, and the insertion buckle 324 is vertically inserted into the socket 3068. In addition, optionally as Figures 13 to 18 , a clamping protrusion 3069 is provided on the outer peripheral surface of the convex structure, and a clamping hole 325 is formed on the second flanging 323, and the clamping protrusion 3069 is clamped into the clamping hole 325.

[0189] During use, the patching block 32 will be installed from top to bottom. At this time, the socket 101 on the first flanging 322 will be inserted into the jack 3068, and the locking hole 325 on the second flanging 323 will cooperate with the locking hole 325, thereby completing the positioning of the patching block 32.

[0190] The installation of the patching block 32 can be achieved through the above-mentioned snap structure. However, the assembly method of the snap structure is prone to falling off under the action of external force. Therefore, the present invention also provides a fixing member to connect the patching block 32 and the box body 31, so as to realize the fastening between the patching block 32 and the box body 31 through the fixing member after the pre-positioning of the patching block 32 is completed by snap and insertion.

[0191] Among them, as Figures 13 to 18 , the first flanging 322 can be screwed to the wall of the recessed structure 307; or the second flanging 323 can be screwed to the wall of the protruding structure.

[0192] In addition, as Figures 13 to 18 , the first flanging 322, the second outer shell 314, the second inner shell 312, and the first inner shell 311 are connected in series by 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.

[0193] Optionally, the cover plate 321 is square, and two adjacent sides of the cover plate 321 are provided with the first flanging 322, and the other two adjacent sides of the cover plate 321 are provided with the second flanging 323.

[0194] As described above, as Figures 13 to 18 , the box body 31 is generally configured in a cuboid shape, and a part of one side of the box body 31 is recessed to form a square recessed structure 307. In this way, a generally square opening will be formed between the recessed structure 307 and the non-recessed part of the box body 31. The square cover plate 321 can be used to close the opening, and the recessed structure 307 formed at this side of the box body 31 will have two adjacent surfaces, which are connected by the two first flangings 322; and the non-recessed part of this side of the box body 31 will also form two adjacent surfaces that are generally at right angles, which are connected by the two second flangings 323.

[0195] The aforementioned recessed structure 307 is provided on the box cover 306 (the combination of the second inner shell 312 and the second outer shell 314). The patching block 32 and the box cover 306 adopt an insertion buckle + snap connection structure. An "E"-type reinforcing rib 3046 structure is designed at the recess of the electric control box 3, and a snap design is adopted for the assembly of the second outer shell 314.

[0196] In addition, the electric control box in the present invention can be arranged vertically, where the vertical direction is perpendicular to the chassis. The horizontal and vertical directions in the present invention are parallel to the chassis, and the horizontal, vertical, and longitudinal directions are perpendicular to each other.

[0197] In addition, in combination with other embodiments of the present invention, a radiator 35 is provided inside the box body 31 of the electric control box 3. The radiator 35 can extend out of the box body 31, and the part of the radiator 35 extending out of the box body 31 can be located at the recessed structure 307, thereby improving the space utilization rate of the electric control box 3.

[0198] In addition, in some embodiments of the present invention, a reactance 34 is provided inside the box body 31 of the electric control box 3, and at least a part of the reactance 34 is arranged inside the convex structure. The internal space of the box body 31 is effectively utilized, and the space utilization rate is improved.

[0199] Such as Figures 1 to 34 In the electric control box 3 of 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 arranged inside the box body 31, and the circuit board 33 has electronic components 331. By integrating the circuit board 33 inside the box body 31, the circuit board 33 is effectively protected, and the production and modular design of the circuit board 33 are facilitated.

[0200] The electric control box 3 in this embodiment can adopt the structure of the electric control box 3 in other embodiments, and the structure of the electric control box 3 in this embodiment can also be applied to other embodiments. For example, the box body 31 of the present invention can adopt the structure of the box body 31 of the aforementioned electric control box 3. In addition, when applying the electric control box 3 to the window air conditioner 1000, the installation method of the electric control box 3 in the aforementioned window air conditioner 1000 can also be adopted.

[0201] In combination with the foregoing embodiments, the circuit board 33 is installed inside the insulating inner shell 303. In addition, optionally, the reactance 34 is installed on the fireproof outer shell 304.

[0202] Furthermore, in combination with the foregoing embodiments, the circuit board 33 is installed on the first inner shell 311. The inner side of the first inner shell 311 is provided with a positioning structure 3019 arranged along the direction of surrounding the circuit board 33. The positioning structure 3019 includes a positioning rib 3020 and a positioning hook 3021. The effective positioning of the circuit board 33 can be achieved through the positioning structure 3019. Refer to the attached Figure 20, in the direction around the circuit board 33, positioning ribs 3020 are provided. The positioning ribs 3020 form a placement area for the circuit board 33 around the circuit board 33, and the circuit board 33 is placed in the space formed by the positioning ribs 3020. In addition, through the positioning hooks 3021, the positioning of the circuit board 33 is achieved. Moreover, positioning ribs 3020 are also provided between the circuit board 33 and the inner surface of the electric control box 3. Through the positioning ribs 3020, the circuit board 33 can be separated from the inner surface of the electric control box 3, facilitating heat dissipation, waterproofing, etc. of the circuit board 33.

[0203] 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 the passage of air flow and forming a better heat dissipation effect.

[0204] Optionally, the positioning ribs 3020 surround a placement space on the first inner shell 311, and the circuit board 33 is arranged in the placement space. The positioning hooks 3021 include a plurality of them arranged at intervals along the circumference surrounding the circuit board 33.

[0205] Optionally, guiding ribs 3022 are provided on the peripheral wall of the placement space. The guiding ribs 3022 are perpendicular to the circuit board 33 and are respectively connected to the inner side surface and the inner bottom surface of the placement space. One end of the guiding rib 3022 far from the inner bottom surface of the placement space is configured as a wedge-shaped structure whose height relative to the inner side surface of the placement space gradually increases in the direction towards the inner bottom surface of the placement space. Through the wedge-shaped structure, the guiding during the installation process of the circuit board 33 can be realized.

[0206] For example, guiding ribs 3022 are provided on one side of the placement space, and positioning hooks 3021 are provided on the other side opposite to the guiding ribs 3022. One side of the circuit board 33 is inserted into the placement space and positioned by the positioning hooks 3021, and then the circuit board 33 is pressed down. Through the action of the guiding ribs 3022, the circuit board 33 can be conveniently and smoothly installed into the placement space.

[0207] Optionally, positioning notches 102 are provided at the edges of the circuit board 33, and positioning protrusions 3072 are provided inside the box body 31. The positioning protrusions 3072 cooperate with the positioning notches 102 to position the circuit board 33. Through the cooperation of the positioning notches 102 and the positioning protrusions 3072, the anti-fool installation of the circuit board 33 can be realized, and the circuit board 33 can be installed in a predetermined orientation to avoid misinstallation and improve the assembly efficiency.

[0208] 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 the passage of air flow and take away the heat on the circuit board 33, improving the heat dissipation of the circuit board 33 and at the same time avoiding the influence of possible condensed water.

[0209] Optionally, a wire routing groove 3027 is provided around the circuit board 33 in the electronic control box 3. A wire-straightening rib 3031 is provided in the wire routing groove 3027 for separating wire harnesses, and fixing ribs 3033 are provided on the electronic control box 3 at intervals along the extending direction of the wire routing groove 3027 to position the wire harnesses.

[0210] At least two wire-straightening grooves include a weak-current wire-straightening groove close to the circuit board and a strong-current wire-straightening groove far from the circuit board, and the weak and strong currents are separated by the wire-straightening ribs.

[0211] Such as Figure 21 and Figure 22 , the electronic control box 3 further includes a reactance 34. The reactance 34 is provided in the box body 31, and the circuit board 33 and the reactance 34 are arranged at intervals, further improving the integration of the electronic control box 3.

[0212] For the electronic control box 3 according to the embodiment of the present invention, integrating the circuit board 33 and the reactance 34 into the electronic control box 3 can facilitate the production and modular design of the electronic control box 3, and facilitate the design, production, and installation of the electronic control structure.

[0213] In addition, when the electronic control box 3 is applied to the window air conditioner 1000, by applying the foregoing electronic control box 3, the stable operation of the window air conditioner 1000 can be ensured, the stability of the window air conditioner 1000 can be improved, the integration rate of the electronic control box 3 can be increased, and the modular design, production, installation, and maintenance of the window air conditioner 1000 can be facilitated.

[0214] Optionally, such as Figure 24 , a partition wall 3018 is provided in the box body 31. The partition wall 3018 separates the circuit board 33 and the reactance 34, and a wire passing port 3037 is provided on the partition wall 3018 to connect the chambers where the circuit board 33 and the reactance 34 are located.

[0215] The reactance 34 can be connected to the circuit board 33. Through the division of the partition wall 3018, the circuit board 33 and the reactance 34 can perform their respective functions and avoid mutual interference. Moreover, the partition wall 3018 can also play a certain heat insulation role to avoid the mutual influence of heat between the circuit board 33 and the reactance 34. The wire passing port 3037 on the partition wall 3018 can be used for the wire harness to pass through to connect the circuit board 33 and the reactance 34.

[0216] Among them, the partition wall 3018 on the box body 31 can be an annular structure, and the reactance 34 is provided inside the annular partition wall 3018.

[0217] Optionally, one end of the reactance 34 is inserted into the box body 31, and the other end of the reactance 34 is connected to the box body 31 through a fixing member, which can facilitate the stable connection between the reactance 34 and the box body 31 and improve the stability of the reactance 34.

[0218] Optionally, the reactance 34 is disposed in the box body 31 , and at least one of a grounding connector and a grounding mark is disposed on the outside of the box body 31 at a position opposite to the reactance 34 .

[0219] Optionally, the multiple screws on the surface of the electrical control box 3 corresponding to the position of the reactance 34 are two for grounding and two for connecting the reactance 34, and the multiple screws are located in the inner recess (i.e., the recess formed by the sink structure 3066 on the outer surface of the box body 31) to prevent the screw heads from being exposed.

[0220] Optionally, in combination with the aforementioned embodiment, the reactance 34 may be configured to be directly mounted on the first housing 313 .

[0221] Alternatively, if Figure 31 The first inner shell 311 is provided with a relief opening 3038, and the reactance 34 is provided at the relief opening 3038 and directly mounted on the first outer shell 313. The relief opening 3038 may be formed by being surrounded by the aforementioned partition wall 3018.

[0222] Optionally, combined Figures 1 to 18 , a part of the first shell 313 is sunken to form a sinking structure 3066 inside the first shell 313, and the reactor 34 is installed on the sinking structure 3066. In this way, more installation space will be provided for the reactor 34, and the reactor 34 can be connected to the sinking structure 3066 through a fixing member. Since the sinking structure 3066 forms a depression on the outer surface of the box body 31, when the reactor 34 and the sinking platform are connected by the fixing member, the fixing member will extend into the depression formed by the sinking structure 3066, effectively protecting the smooth appearance of the electric control box 3, preventing the fixing member from extending out of the outer surface of the electric control box 3, preventing the screw head of the fixing reactor 34 and the grounding screw head from protruding out of the outer surface of the electric control box 3, and preventing injuries during assembly or transportation of components.

[0223] In addition, the sink structure 3066 can also be provided to strengthen the structure.

[0224] In addition, a grounding structure can be provided in the depression formed by the sink structure 3066, and grounding can be achieved through the grounding structure, thereby further improving the safety of the operation of the electric control box 3. The reactor 34 is installed on the sink structure 3066 at the bottom of the box body 31, which, on the one hand, strengthens the structural strength of the sheet metal bottom plate 351, and on the other hand, prevents the screw heads of the reactor 34 and the grounding screw heads from protruding from the electric control bottom plate 351, thereby avoiding injury during assembly.

[0225] Optionally, a grounding structure is provided on at least one of the first housing 313 and the second housing 314 .

[0226] 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 .

[0227] Combined with the foregoing embodiments, a recessed structure 307 is provided on the outer surface of the box body 31, and the relief opening 3058 can be provided on this relief structure.

[0228] In addition, at least a part of the reactance 34 in the present invention can be provided in the protruding structure corresponding to the recessed structure 307.

[0229] Such as Figures 16 to 26 , the reactance 34 and the circuit board 33 are arranged vertically. The reactance 34 can be provided below the circuit board 33 to lower the center of the electronic control box 3 and improve stability. In addition, such as Figures 16 to 26 , the reactance 34 and the box body 31 are positioned by means of a snap 324 plus a fixing member, so that the reactance 34 is stably fixed on the box body 31. The reactance 34 is provided with a grounding screw and a grounding mark, and the grounding screw passes through the box body 31 from the inside of the box body 31. Specifically, because the reactance 34 is heavy in itself, in order to ensure the stability of the center of gravity of the electronic control box 3, the reactance 34 is installed and fixed at a position slightly below the first outer shell 313 and installed on the first outer shell 313. On the one hand, it is beneficial to heat dissipation, and on the other hand, the structure is firm and reliable.

[0230] Optionally, the circuit board 33 is fixedly installed inside the insulating inner shell 303, and the reactance 34 is installed on the fireproof outer shell 304. This can ensure the effective insulation of the circuit board 33, thereby improving the safety of the operation of the circuit board 33, and the reactance 34 is installed on the fireproof outer shell 304, which can improve the stability of the reactance 34.

[0231] This is because, generally, the mass of the reactance 34 is relatively large. By directly installing the reactance 34 on the fireproof outer shell 304, the stability of the reactance 34 can be effectively improved.

[0232] Such as Figures 16 to 26 , the electronic control box 3 further includes a radiator 35. The radiator 35 is connected to at least some of the electronic components 331 on the circuit board 33 and is adapted for heat transfer to form a heat dissipation structure. The circuit board 33 can be dissipated heat through the radiator 35, especially for the electronic components 331 with large heat generation on the circuit board 33, to quickly dissipate heat and avoid faults caused by overheating of the circuit board 33.

[0233] Combined with the foregoing embodiments, optionally, a relief opening 3058 is provided on the wall of the box body 31. The relief opening 3058 can be used for the radiator 35 to protrude, and the radiator 35 protrudes from the box body 31. It is convenient for the radiator 35 to dissipate heat, improves the heat dissipation effect, effectively maintains the operating environment of the circuit board 33, and improves the stability of the operation of the circuit board 33.

[0234] Optionally, such as Figures 16 to 26The heat sink 35 includes: a bottom plate 351 and heat dissipation fins 352. The bottom plate 351 is connected to at least part of the electronic components 331 on the circuit board 33 and is suitable for heat transfer. The bottom plate 351 is located in the box body 31. The heat dissipation fins 352 are connected to the bottom plate 351 and extend out of the box body 31 from the clearance opening 3058. Part of the heat generated during the operation of the circuit board 33 will be transferred to the bottom plate 351, and then the heat on the bottom plate 351 will be transferred to the heat dissipation fins 352. The heat dissipation fins 352 complete the heat dissipation of the corresponding electronic components 331 on the circuit board 33 by exchanging heat with the medium outside the electric control box 3.

[0235] In the present invention, the chassis 1 and the heat dissipation fins 352 of the heat sink 35 can be formed in one piece, thereby effectively improving the heat conduction and heat dissipation efficiency.

[0236] In addition, if Figures 16 to 26 The heat sink 35 may further include a sealing member 353, the sealing member 353 surrounds the heat dissipation fins 352, and the sealing member 353 is disposed between the bottom plate 351 and the periphery of the clearance opening 3058 to form a sealing structure. Through the sealing effect of the sealing member 353, water outside the electric control box 3 can be prevented from entering the electric control box 3 to cause safety hazards.

[0237] Alternatively, if Figures 16 to 26 The surface of the sealing member 353 that abuts against the periphery of the clearance opening 3058 is provided with a plurality of annular ribs 354, which are in the form of annular rings extending along the periphery of the sealing member 353, and the plurality of annular ribs 354 are configured as a plurality of rings arranged at intervals from the inside to the outside. In this way, the plurality of annular ribs 354 will form a multi-layer sealing structure with the periphery of the clearance opening 3058, further improving the sealing effect.

[0238] Optionally, the cross section of the annular rib 354 is configured as a semicircle, a trapezoid or a rectangle;

[0239] In addition, the groove between two adjacent annular ribs 354 can be configured to be semicircular, trapezoidal or rectangular. The second inner shell 312 and the seal 353 are designed to be pressed together, and multiple ribs are designed to press and seal to prevent external water from entering the electric control box 3.

[0240] 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 parts at positions adjacent to both ends of the radiator.

[0241] Alternatively, if Figures 16 to 26, the seal 353 includes a first part 355 and a second part 356. The first part 355 covers the peripheral edge of the surface of the base plate 351 where the heat dissipation fins 352 are connected, and the second part 356 is sleeved on the peripheral surface of the base plate 351. Through the cooperation of the first part 355 and the second part 356, the seal 353 can be stably installed on the base plate 351, effectively improving the stability of the cooperation between the seal 353 and the base plate 351, thereby enhancing the sealing performance between the seal 353 and the box body 31.

[0242] Optionally, the surface of the heat dissipation fin 352 is configured in the shape of a corrugated surface, so as to increase the surface area of the heat dissipation fin 352, thereby enhancing the heat dissipation effect of the heat dissipation fin 352 and improving the heat dissipation effect of the electronic control box 3.

[0243] In addition, in combination with Figures 16 to 26 , heat conducting sheets 358 are provided on at least some of the electronic components 331 on the circuit board 33. The heat conducting sheets 358 conduct heat transfer with the electronic components 331, and the radiator 35 cooperates with the heat conducting sheets 358 and is suitable for heat conduction.

[0244] A gap in the range of 0.1 mm to 1 mm can be provided between the radiator 35 and the heat conducting sheet 358, and a heat conducting medium can be filled in this gap to improve the heat dissipation effect.

[0245] Optionally, a heat dissipation bracket 357 can also be provided on the circuit board 33. During the installation process, the radiator 35 is installed on the heat dissipation bracket 357. A heat conducting medium is filled between the radiator 35 and the heat conducting sheet 358, and heat conduction between the heat conducting sheet 358 and the radiator 35 is carried out through the heat conducting medium.

[0246] In addition, the 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 of the heat generating devices on the circuit board 33 is transmitted to the heat conducting sheet 358 through heat conducting pins, and then the heat is transmitted to the radiator 35 through the heat conducting paste (heat conducting medium) between the heat conducting sheet 358 and the radiator 35. Finally, the radiator 35 transfers the excessive heat outside the electronic control box 3.

[0247] Combined with the foregoing embodiments, a circuit board 33 is provided inside the electronic control box 3. Electronic components 331 are provided on the circuit board 33. Some of the electronic components 331 generate a large amount of heat and need to be dissipated by a radiator 35. The radiator 35 cooperates with the electronic components 331 for heat dissipation. There is a gap between the radiator 35 and the corresponding electronic components 331, and a heat transfer medium (such as silicone) can be filled in this gap. A reactance 34 is provided at the lower part of the electronic control box 3. The reactance 34 is separately arranged from the circuit board 33, and a partition wall 3018 can be arranged between the reactance 34 and the circuit board 33. The lower end of the first outer shell 313 is provided with an installation part 302 extending forward. The bottom of the second inner shell 312 is provided with the installation part 302. This installation part 302 extends out of the rear side of the second inner shell 312 or the second outer shell 314 (or the box body 31). Both installation parts 302 are connected to the chassis 1 through fixing parts. In addition, as can be seen from the drawings, the radiator 35 extends out of the electronic control box 3.

[0248] In addition, as Figures 16 to 26 , an upper part on the right side of the second outer shell 314 is recessed to form a structure for accommodating the extended part of the radiator 35. Reinforcing ribs 3046 are provided on the second outer shell 314, and the reinforcing ribs 3046 straddle the recess and other parts of the second outer shell 314. In addition, after the recessed structure 307 is provided on the second outer shell 314, an opening will be formed at the lower end of the recessed structure 307, and this opening cannot be closed by sheet metal forming. A patch block 32 can be additionally provided for capping. Through the patch block 32, the integrity of the electronic control box 3 can be maintained, the internal space of the box body 31 can be effectively protected, and the stable operation of the electronic control box 3 can be maintained. Part of the edge of the cover plate 321 is provided with a first flanging 322 extending upward. The first flanging 322 is connected to the peripheral wall of the recessed structure 307. Part of the edge of the cover plate 321 extends downward to form a second flanging 323. The second flanging 323 is connected to the peripheral wall of the protruding structure.

[0249] Optionally, the bottom plate 351 and the seal 353 of the radiator 35 are pressed by the second inner shell 312. Fixing parts are respectively provided on both longitudinal sides of the radiator 35. These fixing parts lock the first inner shell 311 and the second inner shell 312 to press the seal 353.

[0250] Combined with the foregoing embodiments, the circuit board 33 is installed inside the box seat 305, and the radiator 35 is installed on the circuit board 33. When the box cover 306 is closed on the box seat 305, the radiator 35 extends out of the box cover 306. At this time, fixing parts can be provided at positions on both sides above the radiator 35 on the box cover 306 to connect and position the box cover 306 and the box seat 305. In this way, the connection between the box cover 306 and the box seat 305 can be facilitated, and moreover, it can be ensured that the seal 353 between the radiator 35 and the box cover 306 is clamped, thereby improving the sealing performance between the radiator 35 and the box cover 306.

[0251] Among them, in combination with other embodiments of the present invention, the circuit board 33 and the radiator 35 are installed on the box base 305. There is a relief opening 3058 on the box cover 306, and the radiator 35 extends out from the relief opening 3058. A seal 353 is provided between the radiator 35 and the inner surface of the box cover 306. On both sides of the radiator 35 along the vertical direction, the first inner shell 311 and the second inner shell 312 are connected by fixing members. One of the fixing members serially fixes the second outer shell 314, the second inner shell 312, and the first inner shell 311 together, and the other fixing member connects the patching block 32 (the first flanging 322), the second outer shell 314, the second inner shell 312, and the first inner shell 311 together.

[0252] Optionally, 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. Through the heat dissipation window 3023, it is convenient for the heat inside the electric control box 3 to exchange heat with the outside of the electric control box 3. Specifically, during use, the heat inside the electric control box 3 will be discharged to the fireproof outer shell 304 through the heat dissipation window 3023. The fireproof outer shell 304 is generally supported by a metal material. In this way, after the heat is transferred to the fireproof outer shell 304, it will be very easy to exchange heat with the external medium of the box body 31, improving the heat dissipation effect of the electric control box 3.

[0253] In addition, since only the heat dissipation window 3023 is provided on the inner shell, and the heat dissipation window 3023 will be closed by the outer shell, while improving the heat dissipation effect, it can also prevent external water, steam, etc. from entering the electric control box 3, ensuring the stable operation of the electric control box 3.

[0254] Optionally, as Figure 27 , a support rib 3024 is connected inside the heat dissipation window 3023, and the support rib 3024 is in the form of a grid arranged in a crisscross pattern. By providing the support rib 3024, the structural strength and stability of the inner shell can be effectively improved.

[0255] Optionally, the circuit board 33 is installed on the first inner shell 311, and a heat dissipation window 3023 is provided in the area of the first inner shell 311 opposite to the circuit board 33 to improve the heat dissipation effect on the circuit board 33.

[0256] Optionally, there is a gap of 8 mm to 18 mm between the circuit board 33 and the first outer shell 313. Keeping a safe distance between the circuit board 33 and the first outer shell 313 can effectively improve the safety of the electric control box 3.

[0257] During the operation of the whole machine, the circuit board 33 generates heat. In particular, the heat generated by some heat-generating components can cause the temperature inside the electric control box 3 to rise too high, thereby damaging other electrical components. Therefore, to solve the heat dissipation problem of the electric control box 3, the back of the electric control board is hollowed out, so that the heat at the clearance position directly contacts the outer sheet metal part (the first outer shell 313), and the heat inside the electric control box 3 is dissipated to the outside of the electric control box 3. To ensure an effective and safe distance between the sheet metal part and the electrical components, the distance D between the circuit board 33 and the second outer shell 314 is 8-18 mm. On the one hand, it is conducive to heat dissipation, and on the other hand, it is for safety regulations considerations.

[0258] Combined with the foregoing embodiments, in the electric control box 3, the reactance 34 and the circuit board 33 are both arranged inside the electric control box 3. The inner surface of the plastic inner cover of the cover of the electric control box 3 has a partition wall 3018, which separates the area of the circuit board 33 and the area of the reactance 34). In addition, a radiator 35 is installed on the circuit board 33, and the radiator 35 extends out of the cover 306 of the electric control box 3. Regarding the connection method between the radiator 35 and the circuit board 33, a seal 353 is arranged around the radiator 35; regarding the structural form and arrangement method of the heat dissipation fins 352 in the radiator 35, the radiator 35 is above the reactance 34; the metal outer box on the outside of the electric control box 3 includes a patch 32, and the patch 32 is located above the reactance 34 to prevent direct sunlight; the circuit board 33 is installed on the plastic inner shell of the seat of the electric control box 3 by means of a buckle, and the structural shape of the plastic inner shell.

[0259] In the electric control box 3 of some embodiments of the present invention, since the electric control box 3 adopts a combination of an insulating inner shell 303 and a fireproof outer shell 304, there may be a problem of water ingress between the insulating outer shell and the fireproof inner shell. Therefore, it is necessary to guide the water in the insulating outer shell and the fireproof inner shell to a direction away from the internal space of the electric control box 3. For this reason, in some embodiments of the present invention, a drainage structure is provided for drainage. The box body 31 of the electric control box 3 can adopt the box body 31 structure described in other embodiments.

[0260] Specifically, as Figures 1 to 34 , the electric control box 3 includes a box body 31. The box body 31 is arranged vertically, and the box body 31 has a first end (referring to the upper end of the box body 31 in the attached drawing) and a second end (referring to the lower end of the box body 31 in the attached drawing) that are opposite in the vertical direction. The box body 31 includes an insulating inner shell 303 and a fireproof outer shell 304. Through the insulating inner shell 303, the effective insulation between the circuit board 33 and the electric control box 3 can be ensured, and the safety of the electric control box 3 can be guaranteed, 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 fails and catches fire, it will not damage the rest of the air conditioner or even cause a fire.

[0261] The insulating inner shell 303 is vertically arranged, and the fireproof outer shell 304 is disposed 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. At this time, the water between the insulating inner shell 303 and the fireproof outer shell 304 may penetrate into the electric control box 3, causing a malfunction of the electric control box 3. Therefore, in the present invention, the drainage groove 3049 is provided. Through the drainage of the drainage groove 3049, the water between the insulating inner shell 303 and the insulating outer shell can be drained to a predetermined position for discharge, thereby ensuring the stable operation of the electric control box 3. The drainage groove 3049 extends to the first end of the box body.

[0262] According to the electric control box 3 of the embodiment of the present invention, the drainage groove 3049 is provided to drain water away from the internal space of the electric control box 3.

[0263] To realize the connection between the electric control box 3 and the housing of the outer box body 22, the top of the outer box body 22 and the fireproof outer shell 304 can be connected by a fixing member. At this time, positioning holes 3070 need to be provided on the fireproof outer shell 304, and the setting of the positioning holes 3070 may cause water to enter between the fireproof outer shell 304 and the insulating inner shell 303 along the fixing member.

[0264] Optionally, at the first end of the box body, the fireproof outer shell 304 is provided with positioning holes 3070, and one end of the drainage groove 3049 extends to the first end and is vertically opposite to the positioning holes 3070. As described above, water may enter between the fireproof outer shell 304 and the insulating inner shell 303 through the positioning holes 3070. At this time, since one end of the drainage groove 3049 is opposite to the positioning holes 3070, the water flow will flow under the drainage action of the drainage groove 3049, thereby discharging the water that enters between the fireproof inner shell and the insulating outer shell to an appropriate position.

[0265] Combined with the foregoing embodiments, the box body 31 includes: an insulating inner shell 303 and a fireproof outer shell 304.

[0266] The insulating inner shell 303 includes a first inner shell 311 and a second inner shell 312 that are longitudinally joined. 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 disposed outside the first inner shell 311, and the second outer shell 314 is disposed outside the second inner shell 312. The drainage groove extends to the first end of the box body.

[0267] Optionally, an outwardly convex structure 3071 protruding vertically away from the second inner shell 312 is provided on the second outer shell 314, and the positioning hole 3070 is provided on the outwardly convex structure 3071. In other words, at the first end of the box body 31, the fireproof outer shell 304 is provided with the outwardly convex structure 3071, and the positioning hole 3070 is provided on the outwardly convex structure 3071. Through the outwardly convex structure 3071, the water entering between the inner and outer shells through the positioning hole 3070 can be reduced, improving the stability and safety of the electric control box 3.

[0268] At the first end of the box body, the second outer shell 314 is provided with a positioning hole 3070, wherein one end of the drainage groove 3049 extends to be vertically opposite to the positioning hole 3070.

[0269] Optionally, at the first end of the box body 31, a rib 3047 protruding vertically away from the inner space of the box body 31 is provided on the edge of the second inner shell 312. 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, blocking the water outside the second outer shell 314 and preventing it from flowing to the mating position between the first inner shell 311 and the second inner shell 312, effectively preventing water.

[0270] Optionally, the distance L1 between the rib 3047 and the positioning hole 3070 is not less than 6 mm. Ensure that media such as water will not flow to the joint of the first inner shell 311 and the second inner shell 312.

[0271] Optionally, at the first end of the box body 31, the end face of the second inner shell 312 is inclined towards the second end of the box body 31 in the direction longitudinally away from the first inner shell 311. The water dripping onto the second outer shell 314 and the water entering the second inner shell 312 will flow along the inclined end face under the action of gravity, preventing it from flowing to the mating position between the first inner shell 311 and the second inner shell 312.

[0272] Optionally, at the first end of the box body 31, one end of the drainage groove 3049 extends to the end face 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 opposite to the positioning hole 3070. By providing the relief groove 3050, when connecting the box body of the window air conditioner 1000 and the box body 31 through a fixing member, the fixing member will not contact the second inner shell 312, ensuring that the second inner shell 312 is not damaged and improving the waterproof performance of the electric control box 3. In addition, the relief groove 3050 forms an inlet of the drainage groove 3049, which can quickly discharge the water entering between the fireproof outer shell 304 and the insulating inner shell 303.

[0273] Optionally, at the first end of the box body 31, at least a part of the end face of the second inner shell 312 is spaced apart from the second outer shell 314 and is provided with a plurality of rib strips 3051. The rib strips 3051 extend along the vertical and longitudinal directions, and the plurality of rib strips 3051 are arranged at intervals along the transverse direction. A relief groove 3050 is formed between two adjacent rib strips 3051.

[0274] Specifically, the insulating inner shell 303 is provided with a plurality of rib strips 3051 at the first end. The plurality of rib strips 3051 are arranged at intervals along the transverse direction (i.e., the left-right direction in the figure), and the rib strips 3051 extend along the longitudinal direction (referring to the front-back direction in the figure). In this way, a groove is formed between two adjacent rib strips 3051, which can receive the water entering through the positioning holes 3070, facilitating the drainage of the water entering between the inner and outer shells.

[0275] In addition, a drainage groove 3049 is provided on the outer surface of the insulating inner shell 303. Generally, the insulating inner shell 303 is made of a plastic part, while the fireproof outer shell 304 is made of a sheet metal part. It is often easier to form the drainage groove 3049 on the plastic part than on the sheet metal part. Therefore, by arranging the drainage groove 3049 on the insulating inner shell 303, the production process can be effectively simplified in the present invention.

[0276] Furthermore, in combination with the sealing structure between the first inner shell 311 and the second inner shell 312 in the foregoing embodiment, the waterproof performance of the electric control box 3 can be further improved.

[0277] Optionally, the top wall of the box body assembly 2 is connected to the first end of the electric control box 3 by screws. By screw connection, the stability of the electric control box 3 can be effectively improved. Especially during the transportation and drop test, the electric control box 3 can still maintain a stable state.

[0278] Optionally, the top wall of the box body assembly 2 is provided with an inner concave structure 205, and the first end of the electric control box 3 is provided with an outer convex structure 3071. The inner concave structure 205 and the outer convex structure 3071 are connected by a fixing member. The cooperation between the inner concave structure 205 of the box body assembly 2 and the outer convex structure 3071 of the electric control box 3 can facilitate the connection of the fixing member between the box body assembly 2 and the electric control box 3. Moreover, the inner concave structure 205 can be used to accommodate the head of the screw, ensuring the flatness of the outer surface of the box body assembly 2.

[0279] The provision of the inner concave structure 205 can prevent the screw head of the outer box from protruding from the outer surface of the outer box, and design a recessed area for the screw. There will be a little rainwater remaining and gathering at this position. Therefore, a drainage groove 3049 is designed corresponding to the external screw connection. This can prevent the water droplets penetrating from the screw holes of the outer box from remaining on the electric control box 3 and drain into the chassis 1 along the drainage groove 3049 for secondary utilization (usually, the condensed water in the chassis 1 is used to cool the condenser by the axial flow fan 225 to lift the product capacity and energy efficiency).

[0280] The electronic control box 3 is vertically installed on one side of the outdoor air duct. To avoid excessive shaking, a screw at the top of the electronic control box 3 is connected and fixed to the outer box. The opening of the louver part of the outer box (i.e., the air inlet 203 on the side of the outer box shell 221 away from the chassis 1) is located above the electronic control box 3. The cover of the sheet metal electronic control box 3 has no opening design to prevent water splashing from the outside into the electronic control box 3.

[0281] Optionally, in the window air conditioner 1000 with this electronic control box 3, the outer box body 22 includes an outer box shell 221. The electronic control box 3 is arranged inside the outer box shell 221, and the electronic control box 3 is connected to the outer box shell 221 through a fixing member. Optionally, the fixing member cooperates with the aforementioned positioning hole 3070.

[0282] Optionally, louvers are provided on the side of the box body assembly 2 away from the chassis 1. The louvers are opposite to the second outer shell. At the first end of the box body, a rib protruding in the vertical direction away from the inner space of the box body is provided at the edge of the second inner shell. The rib protrudes vertically from the edge of the second outer shell. A flanging rib is provided on the periphery of the louver. The distance between the flanging rib and the rib is not less than 6 mm to facilitate air intake and heat dissipation of the electronic control box 3.

[0283] The louvers are vertically opposite to the second outer shell, or in other words, the louvers are vertically offset from the first outer shell. When water enters the outer box body 22 through the louvers, it will splash onto the second outer shell 314. The water from outside the outer box louver only flows down to a partial area at the top of the sheet metal electronic control box 3 cover and will flow into the chassis 1 along the outer surface of the sheet metal electronic control box 3. In addition, a flanging rib 207 extending into the outer box body 22 is provided on the periphery of the louver. The distance L2 between the flanging rib 207 and the aforementioned rib 3047 is not less than 6 mm. This is beneficial for the exclusion of water at the top of the electronic control box 3 and prevents it from entering the electronic control box 3, thus affecting the product quality.

[0284] Optionally, through heat dissipation holes 3059 are provided on the side wall of the insulating inner shell 303. The heat dissipation holes 3059 are inclined towards the second end in the direction from inside to outside. In this way, the heat inside the insulating inner shell 303 will be dissipated through the heat dissipation holes 3059. Due to the protection of the fireproof outer shell 304 outside the insulating inner shell 303, external water, steam, etc. will not enter the box body 31 through the heat dissipation holes 3059, while the heat can be dissipated through the fireproof outer shell 304, thus achieving the functions of waterproofing, fireproofing, and heat dissipation.

[0285] Optionally, at least a part of the peripheral wall of the heat dissipation hole 3059 protrudes from the outer side surface of the insulating inner shell 303. The protrusion of the peripheral wall of the heat dissipation hole 3059 can separate the insulating inner shell 303 from the insulating outer shell, so that there is an air flow channel between the inner and outer shells for air flow, further improving the heat dissipation effect of the electronic control box 3.

[0286] Optionally, the peripheral walls of the heat dissipation holes 3059 all protrude from the side surface of the insulating inner shell 303. The length of the side wall of the heat dissipation hole 3059 protruding near the first end is greater than the length of the side wall of the heat dissipation hole 3059 protruding near the second end, and a notch groove 3060 is provided at the edge of the side wall of the heat dissipation hole 3059 near the first end. In this way, the heat dissipation holes 3059 will not be blocked by the fireproof outer shell 304, facilitating the hot air inside the insulating inner shell 303 to be sent out through the heat dissipation holes 3059 and improving the heat dissipation effect. In addition, by providing the notch groove 3060 on the heat dissipation holes 3059, the overall circulation of the air flow inside the electric control box 3 can be facilitated.

[0287] As described above, for the purpose of assisting in the heat dissipation inside the electric control box 3, the side wall of the second inner shell 312 is designed with obliquely downward openings; the second outer shell 314 has no opening design. The heat inside the electric control box 3 can transfer the heat to the outer second outer shell 314 through the openings, so that the internal heat is dissipated, reducing the internal temperature of the electric control box 3 and being beneficial to extending the service life of electrical components. The side wall is designed with an obliquely downward opening structure, which can prevent the water seeping in from the gap of the top sheet metal electric control box 3 cover from flowing in through the oblique holes and flowing downward, avoiding flowing into the electric control box 3.

[0288] Optionally, in combination with the foregoing embodiments, the insulating inner shell 303 includes a first inner shell 311 and a second inner shell 312 that are spliced together, and both the first inner shell 311 and the second inner shell 312 are vertically arranged. Through the splicing of the first inner shell 311 and the second inner shell 312, the forming of the insulating inner shell 303 can be facilitated, which is convenient for the installation of the internal electronic components 331, circuit boards 33, etc. of the electric control box 3, improving the assembly efficiency of the electric control box 3 and facilitating maintenance. The fireproof outer shell 304 includes a first outer shell 313 and a second outer shell 314. The first outer shell 313 covers the outside of the first inner shell 311, and the second outer shell 314 covers the outside of 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. The first outer shell 313 is provided with a positioning hole 3070 at the first end, and the end surface of the first inner shell 311 at the first end is configured to incline towards the second end in a direction away from the second inner shell 312. This simplifies the structure of the box body 31 and facilitates the diversion of the water entering the inside of the first outer shell 313 through the positioning hole 3070, avoiding damage to the electric control box 3.

[0289] Optionally, in combination with the foregoing embodiments, 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. The connecting portion 3043 is provided with a threaded hole, and the threaded hole is a blind hole. Further, it is characterized in that the connecting portion 3043 is provided with an opening.

[0290] Optionally, at the second end of the box body 31, a wind guiding notch 3052 is provided on the insulating inner shell 303. The wind guiding notch 3052 penetrates through the inner and outer spaces of the insulating inner shell 303, and the interior of the wind guiding notch 3052 is configured as a circuitously extending flow channel. By providing the wind guiding notch 3052, air flow can flow through the wind guiding notch 3052, thereby dissipating heat from the internal space of the electric control box 3, improving the heat dissipation efficiency and effect. It effectively maintains the operating environment of the electric control box 3 and reduces the failure rate of the electric control box 3.

[0291] Optionally, at the second end of the box body 31, a first baffle 3061, a second baffle 3062, and a third baffle 3063 are provided on the insulating inner shell 303. Ventilation openings are provided on the first baffle 3061 and the second baffle 3062 in a vertically opposite manner, and the third baffle 3063 is spaced between the three air vents of the first baffle 3061 and the second baffle 3062. Through the first baffle 3061, the second baffle 3062, and the third baffle 3063, a circuitous flow channel is formed in combination, with a simple structure and convenient molding.
