[0052] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0053] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] An air conditioner usually includes an indoor unit installed indoors and an outdoor unit installed outdoors. The indoor unit and the outdoor unit are connected by pipes to achieve the effect of transferring heat and exchanging indoor and outdoor gases. In order to reduce costs and facilitate the installation of air conditioners, an air conditioner is proposed in the related art. The air conditioner can integrate the outdoor unit and the indoor unit (that is, the outdoor unit and the indoor unit no longer need to be connected by other structures, and the internal components of the two are all set in the same shell), and the air conditioner can be installed on the window, thereby connecting the indoor and outdoor, thereby achieving the effect of transferring heat and exchanging indoor and outdoor gases. The air conditioner includes a motor, fan blades, a rear panel, and an electrical control box. The rear panel can be used to install the motor and can protect the fan blades to prevent other components from interfering with the rotation of the fan blades. The electrical control box is used to control the normal operation of the air conditioner. Bolts are usually used to connect the electronic control box to the rear panel. However, since the motor will inevitably vibrate during operation, the vibration transmitted to the rear panel may cause the threaded fasteners connecting the electronic control box to the rear panel to loosen, thereby causing the connection between the electronic control box and the rear panel to fail, resulting in the air conditioner not being able to use normally and other problems.

[0055] In view of this, referring to Figures 1 to 20, the present application provides an air conditioner 10. Specifically referring to Figures 1 to 3, the air conditioner 10 includes an air supply assembly 300, a positioning bracket 210, a frame 220, and an electrical control box 100. The air supply assembly 300 includes a motor 310 and fan blades 320. The fan blades 320 can be arranged in a channel connecting the air conditioner 10 to the indoor environment, or in a channel connecting the air conditioner 10 to the outdoor environment. The fan blades 320 are connected to the motor 310, and the motor 310 can drive the fan blades 320 to rotate. In one embodiment, the fan blades 320 are driven to rotate so as to drive the air flow to flow toward the heat exchanger. The air flow contacts the heat exchanger so that the heat of the heat exchanger can be transferred to the indoor environment (or outdoor environment) through the air flow. The arrangement of the fan blades 320 can accelerate the flow of air, thereby improving the heat exchange efficiency of the heat exchanger. In another embodiment, the fan blades 320 are driven to rotate by the motor 310 to generate an air flow, which can evenly distribute the cold air and warm air in the room to various locations in the room. In addition, the rotation of the fan blades 320 can drive air into the air conditioner 10 (or drive air out of the air conditioner 10), thereby realizing the circulation of indoor and outdoor air.

[0056] Referring to Figures 1 to 4, in some embodiments, the positioning bracket 210 can be connected to the frame 220 and combined to form the rear panel 200 (in other embodiments, the positioning bracket 210 can be separated from the frame 220). The positioning bracket 210 can be used to install the motor 310. The frame 220 is arranged around the circumference of the fan blade 320. The frame 220 can provide space for the rotation of the fan blade 320, prevent other components from interfering with the rotation of the fan blade 320, and prevent the fan blade 320 from damaging other components that accidentally enter the rotation range of the fan blade 320 when rotating. The electric control box 100 generally includes a controller, a switch, a sensor, etc. The electric control box 100 can control the start and stop of the air conditioner 10, thereby adjusting the indoor temperature and preventing the indoor temperature from being too high or too low. The electric control box 100 can also provide power protection and short-circuit protection for the air conditioner 10 to prevent the air conditioner 10 from malfunctioning due to problems such as circuit short circuit and power overload. In addition, the setting of the electric control box 100 can also integrate the internal information of the air conditioner 10 and the external system information and perform communication control on the air conditioner 10, so that the air conditioner 10 can be suitable for different environments and meet different energy consumption requirements.

[0057] Referring to Figures 3-4, 6, 10, and 17, the positioning bracket 210 is provided with a slot 211, the frame 220 includes a first positioning structure 223, and the electrical control box 100 includes a protrusion 111 and a second positioning structure 130. For ease of description, the direction from the motor 310 toward the slot 211 is defined as a first direction X, and the first direction X is substantially perpendicular to the rotation axis of the motor 310. The direction substantially perpendicular to the first direction X is defined as a second direction Y. As shown in Figure 3, the second direction Y is also substantially perpendicular to the rotation axis of the motor 310. It should be noted that the first direction X is considered to be substantially perpendicular to the rotation axis of the motor 310 as long as the angle between the first direction X and the rotation axis of the motor 310 is within a range of no less than 75 degrees and no greater than 105 degrees. For example, the angle between the first direction X and the rotation axis of the motor 310 can be 75 degrees, 85 degrees, 90 degrees, 100 degrees, 105 degrees, etc. Similarly, if the angle formed between the second direction Y and the first direction X is within a range of not less than 75 degrees and not more than 105 degrees, the second direction Y can be considered to be substantially perpendicular to the first direction X. For example, the angle between the second direction Y and the first direction X can be 75.5 degrees, 85.7 degrees, 90.4 degrees, 99.6 degrees, 105 degrees, etc. If the angle formed between the second direction Y and the rotation axis of the motor 310 is within a range of not less than 75 degrees and not more than 105 degrees, the second direction Y can be considered to be substantially perpendicular to the rotation axis of the motor 310. For example, the angle between the second direction Y and the rotation axis of the motor 310 can be 75 degrees, 84.2 degrees, 90 degrees, 101.3 degrees, 105 degrees, etc.

[0058] Specifically referring to FIG. 4 , the protrusion 111 can be inserted into the slot 211 along the second direction Y, and the second positioning structure 130 can be connected to the first positioning structure 223, thereby enabling the electric control box 100 to be quickly connected to the rear panel 200. The rear panel 200 can provide support for the electric control box 100, preventing damage from collision with other components within the air conditioner 10 during transportation and use of the air conditioner 10 due to vibration or impact. The protrusion 111 is configured to be restrained by the slot 211 to prevent it from separating from the slot 211 along the first direction X. This prevents the electric control box 100 from being affected by vibration generated by the motor 310 during operation and from separating from the positioning bracket 210. In other words, when the motor 310 vibrates, because the mounting direction of the protrusion 111 (the protrusion 111 is mounted in the retaining groove 211 along the second direction Y) is perpendicular to the direction in which the vibration force acts on the electrical control box 100, the component of the vibration force in the second direction Y is eliminated. This reduces the risk of damage to the electrical control box 100 due to the vibration of the motor 310 and improves the stability of the air conditioner 10. Furthermore, with the component of the vibration force in the second direction Y eliminated, the retaining groove 211 restricts the protrusion 111 along the first direction X, preventing the protrusion 111 from disengaging from the retaining groove 211 along the first direction X. This reduces the risk of displacement and stress on the protrusion 111 (and thus the electrical control box 100) due to the vibration of the motor 310, further ensuring the effectiveness of the connection between the electrical control box 100 and the rear panel 200. Specifically, the latching slot 211 has an accommodating cavity extending along the second direction Y. At least one end of the accommodating cavity has a notch 2111 along the second direction Y, through which the protrusion 111 can be inserted into the accommodating cavity. The latching slot 211 has a restraining effect on the protrusion 111 along the first direction X, thereby limiting the freedom of the electric control box 100 along the first direction X and preventing it from being separated from the positioning bracket 210 due to vibration of the motor 310. Referring to Figures 4 and 9, specifically, the latching slot 211 has an inner peripheral wall 2112, which is arranged around an axis parallel to the second direction Y. The inner peripheral wall 2112 is arranged around the protrusion 111, and the protrusion 111 can move along the first direction X until it abuts the inner peripheral wall 2112.

[0059] For example, the angle formed between the first direction X and the rotation axis is 90 degrees, and the angle formed between the second direction Y and the first direction X is 75 degrees. When the motor 310 vibrates, the component of the vibration force in the second direction Y is relatively small. This component of the vibration force in the second direction Y is significantly smaller than the force exerted by the electronic control box 100 on the rear panel 200 (such as the weight of the electronic control box 100 and the locking force of the first connecting piece 121 secured to the frame 220 by the threaded fasteners). This vibration force cannot disengage the protrusion 111 from the slot 211, thereby ensuring the effective connection of the electronic control box 100.

[0060] In the embodiment of the present application, the protrusion 111 can be inserted into the slot 211 along the second direction Y, which is perpendicular to the direction of the vibration force generated by the motor 310 during operation. Furthermore, the protrusion 111 is configured to be restrained by the slot 211 to prevent it from being disengaged from the slot 211 along the first direction X. This ensures the effectiveness of the connection between the electric control box 100 and the rear panel 200. Furthermore, the electric control box 100 can be connected to the positioning bracket 210 by directly inserting the protrusion 111 into the slot 211, making installation of the electric control box 100 even simpler and more convenient. Compared with the installation method in the related art, in which threaded fasteners are used to connect the electric control box 100 to the positioning bracket 210 (the threaded fasteners are sequentially passed through the positioning bracket 210 and the electric control box 100 in the direction from the positioning bracket 210 to the electric control box 100 and tightened. Due to the limited internal space of the air conditioner 10, it is not conducive to the installation of threaded fasteners), the mutual cooperation between the protrusion 111 and the slot 211 can install the electric control box 100 on the positioning bracket 210 within a limited space, avoiding the electric control box 100 from being affected by other parts and structures inside the air conditioner 10 during the installation process, reducing the installation difficulty of the electric control box 100, and reducing labor costs.

[0061] In some embodiments, as shown in FIG13 , the side of the slot 211 facing away from the motor 310 along the first direction X is not provided through the slot 211. Instead, the protrusion 111 includes a first engaging portion 1112 and a second engaging portion 1113. The first engaging portion 1112 is connected to the main body of the electrical control box 100 at one end, facing away from the motor 310, along the first direction X. The other end is connected to the second engaging portion 1113. The second engaging portion 1113 extends along the second direction Y and is insertable into the accommodating cavity through the notch 2111 along the second direction Y. The first engaging portion 1112 and the second engaging portion 1113 together form an L-shaped structure. In other embodiments, as shown in FIG4 , FIG8 , and FIG9 , the side of the slot 211 facing away from the motor 310 may also be provided through the slot 211, with one end of the protrusion 111 extending out of the slot 211 along the first direction X. Specifically, the accommodating cavity extends through the side of the slot 211 facing away from the motor 310 along the first direction X. For ease of description, the slot 211 is defined as having an opening along the first direction X and on the side away from the motor 310, and the opening is connected to the notch 2111 and the accommodating cavity. One end of the protrusion 111 along the first direction X is connected to the electric control box 100, and the other end can be inserted into the accommodating cavity through the notch 2111 along the second direction Y. During this process, the end of the protrusion 111 close to the electric control box 100 can move in the opening. The provision of the opening makes the structure of the protrusion 111 simpler. In addition, when the motor 310 vibrates, the force exerted on the interface between the protrusion 111 and the electric control box 100 is along the first direction X, and only a small shear force is exerted on this portion. Therefore, the design of the opening can extend the service life of the protrusion 111, reduce the maintenance frequency of the air conditioner 10, and thereby reduce the maintenance cost of the air conditioner 10.

[0062] To effectively prevent the electric control box 100 from detaching from the positioning bracket 210 along the first direction X, in some embodiments, referring to Figures 1-4, as well as Figures 9, 14, and 15, for ease of description, a direction perpendicular to the first direction X and the second direction Y is defined as the third direction Z. Along the first direction X, the width of the slot 211 along the third direction Z gradually decreases or decreases in a stepwise manner. The structural shape of the protrusion 111 is adapted to the structural shape of the slot 211 to ensure that the protrusion 111 can be smoothly inserted into the slot 211 and does not detach from the slot 211 along the first direction X. That is, in one embodiment, the width of the slot 211 along the third direction Z decreases linearly along the first direction X. It should be noted that this linearity can be either linear or curved, i.e., the variation in the width of the slot 211 along the third direction Z along the first direction X can be uniform or uneven. Specifically, the projection plane is perpendicular to the second direction Y, and the outline of the projection formed by the slot 211 on the projection plane can be similar to a "Λ" shape, a "⌒" shape, or a "︹" shape. In another embodiment, along the first direction X, the slot 211 decreases in width along the third direction Z at specific intervals or in a "staircase"-like direction. Specifically, the projection plane is perpendicular to the second direction Y, and the outline of the projection formed by the slot 211 on the projection plane can be similar to a "∠" shape, a "┴" shape, or a "└" shape. Since the slot width (the dimension of the slot 211 in the third direction Z) decreases along the first direction X, after the protrusion 111 is inserted into the slot 211, the slot 211 can increase the restraining force on the protrusion 111 by the slot width changing along the first direction X, thereby improving the connection stability between the protrusion 111 and the slot 211, preventing the protrusion 111 from separating from the slot 211 along the first direction X due to the vibration generated by the motor 310, and ensuring the effectiveness of the connection between the electric control box 100 and the positioning bracket 210.

[0063] To enhance the support provided by the positioning bracket 210 to the electric control box 100, in some embodiments, as shown in Figures 4, 8, and 9, the positioning bracket 210 includes a positioning boss 212 having a first positioning wall 2121 facing away from the motor 310. After the protrusion 111 is inserted into the slot 211, one side of the electric control box 100 can abut against the first positioning wall 2121. Because the electric control box 100 is also connected to the first positioning structure 223 (located in the frame 220) via the second positioning structure 130, and the frame 220 is in turn connected to the positioning bracket 210, the provision of the positioning boss 212 can further enhance the connection stability between the electric control box 100 and the positioning bracket 210, thereby providing additional support for the electric control box 100. In other embodiments, the positioning boss 212 can also be provided on the electric control box 100. Specifically, the positioning boss 212 can be disposed on a side of the electrical control box 100 near the motor 310, and the positioning boss 212 protrudes relative to the surface of the electrical control box 100. The positioning bracket 210 is provided with a positioning slot. When the protrusion 111 is inserted into the slot 211 along the second direction Y, the positioning boss 212 can be locked into the positioning slot. After the electrical control box 100 is installed on the rear panel 200, the positioning slot and the positioning boss 212 can limit the movement of the electrical control box 100 along the second direction Y. The positioning boss 212 can also provide additional support for the electrical control box 100, thereby improving the stability of the installation of the electrical control box 100.

[0064] In some embodiments, referring to Figures 4, 8, and 9, the slot 211 includes a notch 2111 located on one side along the second direction Y. A first positioning wall 2121 is provided on a side of the slot 211 facing away from the notch 2111 along the second direction Y. Specifically, after the protrusion 111 is inserted into the slot 211 via the notch 2111, one side of the electric control box 100 can abut against the first positioning wall 2121. When the electric control box 100 is moved by vibration from the motor 310, the first positioning wall 2121 and the slot 211 provide a resistive force in a direction opposite to the vibration force, thereby maintaining a secure connection between the electric control box 100 and the rear panel 200 and preventing the protrusion 111 from disengaging from the notch 211, which could cause the connection between the electric control box 100 and the positioning bracket 210 to fail. In other embodiments, referring to Figures 4, 8, and 9, the first positioning wall 2121 is located on the side of the slot 211 along the first direction X that faces away from the motor 310. In one embodiment, the first positioning wall 2121 is further away from the motor 310 than the slot 211, i.e., the distance between the first positioning wall 2121 and the rotation axis is greater than the distance between the side of the slot 211 along the first direction X that faces away from the motor 310 and the rotation axis. After the protrusion 111 is inserted into the slot 211 via the notch 2111, one side of the electrical control box 100 can abut against the first positioning wall 2121. The first positioning wall 2121 can provide additional support for the electrical control box 100, further enhancing the stability of the connection between the electrical control box 100 and the positioning bracket 210.

[0065] To prevent the vibration of the motor 310 from being transmitted to the electrical control box 100 through the slot 211 and damaging the conductive components within the electrical control box 100, in some embodiments, referring to Figures 4, 8, and 9, the protrusion 111 has an outer peripheral wall 1111. The outer peripheral wall 1111 is arranged around the axis of the protrusion 111 parallel to the second direction Y, and the outer peripheral wall 1111 is spaced apart from the groove wall of the slot 211. That is, after the protrusion 111 is inserted into the slot 211, a gap is formed between the outer peripheral wall 1111 of the protrusion 111 and the groove wall of the slot 211. When the motor 310 vibrates, all structures connected to the motor 310 will be affected by the vibration. Because the outer peripheral wall 1111 of the protrusion 111 is spaced apart from the wall of the slot 211, when the vibration of the motor 310 is transmitted to the slot 211, the gap between the outer peripheral wall 1111 and the wall isolates the vibration generated by the motor 310 from the gap. (The gap can reduce the efficiency of the vibration transmitted from the motor 310 through the slot 211 to the electric control box 100 when the motor 310 vibrates, and can even interrupt the transmission of the vibration to the electric control box 100.) This effectively protects the electric control box 100 and its internal components, and reduces the risk of connection failure between the conductive components within the electric control box 100. In one embodiment, to effectively reduce the impact of the vibration generated by the motor 310 on the electric control box 100, a buffer component can be provided between the outer peripheral wall 1111 of the protrusion 111 and the wall of the slot 211. The buffer component can be sponge, rubber, polyurethane foam, etc. In other embodiments, the outer peripheral wall 1111 of the protrusion 111 abuts against the groove wall of the slot 211 (the end of the protrusion 111 close to the motor 310 may abut against the groove wall of the slot 211, or the side wall of the protrusion 111 facing away from the motor 310 may abut against the groove wall of the slot 211, or both groove walls of the slot 211 may abut against the outer peripheral wall 1111 of the protrusion 111), thereby firmly installing the electric control box 100 on the positioning bracket 210 to improve its integrity.

[0066] To effectively protect the components within the electrical control box 100, in some embodiments, as shown in Figures 16-18 , the electrical control box 100 includes a first housing 110, a second housing 120, and a conductive element. The conductive element is disposed within the first housing 110, and the second housing 120 is enclosed within the first housing 110. The material used for the second housing 120 can be stronger and more durable than that used for the first housing 110. Thus, the second housing 120 protects the first housing 110 and the conductive element, preventing deformation or even damage to the first housing 110 caused by external forces, which could affect the proper functioning of the conductive element. The conductive element can be a component that conducts electricity, a component that conducts current during operation, or a combination of both. Specifically, the conductive element can be an inductor, a capacitor, a resistor, a connector, a wire, or a combination of these components. The second housing 120 can be made of metal, while the first housing 110 can be made of plastic. The second housing 120 can be formed by sheet metal stamping, while the first housing 110 can be injection molded. In one usage scenario, when a fire occurs, the second shell 120 can protect the first shell 110, preventing the fire outside the second shell 120 from spreading to the first shell 110 and causing damage to the conductive components inside the electric control box 100 (the electric control box 100 is one of the most important components of the air conditioner 10, responsible for controlling the various functions and operations of the air conditioner 10, and ensuring the performance and reliability of the air conditioner 10). In another usage scenario, when a fire occurs inside the first shell 110, the second shell 120 can isolate the fire, preventing the fire from spreading outside the second shell 120 and affecting other components of the air conditioner 10, or even affecting the safety of the user's life and property. In addition, since the second shell 120 is made of metal, it can act as an electromagnetic shield for the conductive components set in the first shell 110, effectively reducing external electromagnetic interference and preventing it from affecting the normal operation of the conductive components, thereby improving the anti-interference ability of the electric control box 100. The first shell 110 is made of plastic, which has excellent insulation properties and can insulate and protect the conductive components.

[0067] Referring to Figures 16-18 , the second housing 120 has an opening, and the first housing 110 includes a protrusion 111. This protrusion 111 can be inserted through the opening and inserted into the slot 211. Specifically, since the first housing 110 is an injection-molded part, the protrusion 111 can also be an injection-molded part, and the protrusion 111 can be integrally molded with the first housing 110. Providing the protrusion 111 on the first housing 110 can reduce the overall weight of the air conditioner 10, thereby reducing the transportation and installation costs of the air conditioner 10. Furthermore, providing the protrusion 111 on the first housing 110 can simplify the production process and reduce production costs (if the protrusion 111 is provided on the first housing 110, the protrusion 111 can be integrally molded with the first housing 110). In another embodiment, the protrusion 111 can also be provided on the second housing 120, which is made of metal. To enhance the connection reliability between the protrusion 111 and the second housing 120, the protrusion 111 can also be made of metal. The second housing 120 can be formed by sheet metal stamping, and the protrusion 111 can be connected to the second housing 120 by welding or other methods. Providing the protrusion 111 on the second housing 120 can reduce the mold cost of producing the first housing 110.

[0068] In some embodiments, referring to Figures 5-12 , the frame 220 includes a connecting side 221 located on the side of the slot 211 facing away from the motor 310 along the first direction X. The connecting side 221 has a second positioning wall 2211 facing away from the rotation axis. The first positioning structure 223 includes a first connecting hole 2213 provided in the second positioning wall 2211. The second positioning structure 130 includes a first connecting piece 121 capable of abutting the second positioning wall 2211 and being threadedly connected to the first connecting hole 2213. Specifically, the first connecting piece 121 has a second connecting hole 1213 that extends through the first connecting piece 121. As the protrusion 111 is inserted into the slot 211 along the second direction Y, the first connecting piece 121 gradually approaches and gradually blocks the second positioning wall 2211. When the protrusion 111 is fully inserted into the slot 211, the first connecting piece 121 abuts the second positioning wall 2211, and the second connecting hole 1213 aligns with the first connecting hole 2213. The threaded fastener is inserted into the second connecting hole 1213 and the first connecting hole 2213 and tightened, thereby securing the electric control box 100 to the frame 220 and further improving the stability of the connection between the electric control box 100 and the rear panel 200. In one embodiment, the first connecting piece 121 can also be provided on the first housing 110, in which case the first connecting piece 121 is an injection-molded part. In another embodiment, the first connecting piece 121 can also be provided on the second housing 120, in which case the first connecting piece 121 is made of metal. The threaded connection between the first connecting hole 2213 and the second connecting hole 1213, combined with the cooperation between the protrusion 111 and the slot 211, not only improves the stability of the connection between the electric control box 100 and the rear panel 200, but also facilitates assembly and maintenance of the air conditioner 10.

[0069] In a specific embodiment, referring to Figures 5 to 12, the first connecting piece 121 has a first positioning position and a second positioning position abutting against the second positioning wall 2211. The first connecting piece 121 is configured to be able to slide from the first positioning position to the second positioning position along the second direction Y. When the first connecting piece 121 is in the first positioning position, the protrusion 111 is outside the card slot 211 (the protrusion 111 is in a pre-inserted card slot 211 state), and the first connecting hole 2213 and the second connecting hole 1213 are staggered. When the first connecting piece 121 is in the second positioning position, the protrusion 111 is inside the card slot 211 (i.e., the protrusion 111 is already inserted into the card slot 211), and the first connecting hole 2213 is aligned with the second connecting hole 1213. The threaded fasteners are sequentially inserted into the first connecting hole 2213 and the second connecting hole 1213 and tightened, thereby connecting the first connecting piece 121 to the frame 220. By inserting the protrusion 111 into the slot 211 and simultaneously connecting the first connecting piece 121 to the connecting side 221 using threaded fasteners, the electric control box 100 can be conveniently connected to or removed from the rear panel 200. In other embodiments, the slot 211 can also extend along the third direction Z, and the protrusion 111 can be inserted into the slot 211 along the third direction Z. The first positioning position and the second positioning position are arranged along the third direction Z, and the first connecting piece 121 can slide along the third direction Z from the first positioning position to the second positioning position along the third direction Z. When the first connecting piece 121 is in the first positioning position, the protrusion 111 is outside the slot 211, and the position of the first connecting hole 2213 is staggered with the position of the second connecting hole 1213. When the first connecting piece 121 is in the second positioning position, the protrusion 111 is in the slot 211, the first connecting hole 2213 is aligned with the second connecting hole 1213, and the threaded fasteners are inserted into the first connecting hole 2213 and the second connecting hole 1213 in sequence and tightened, so that the first connecting piece 121 is connected to the frame 220.

[0070] To ensure that the second connection hole 1213 is accurately aligned with the first connection hole 2213 when the first connection piece 121 is in the second positioning position, in some embodiments, see Figures 5-12, the connecting side 221 further includes an abutment portion 222. The abutment portion 222 is located on the side of the second positioning position away from the first positioning position. The first connection piece 121 is configured to abut against the abutment portion 222 when it is in the second positioning position. Specifically, when the first connecting piece 121 slides from the first positioning position to the second positioning position, the abutment portion 222 provides a certain restraining force for the first connecting piece 121, and the first connecting piece 121 can naturally abut the abutment portion 222, so that the second connecting hole 1213 can be quickly aligned with the first connecting hole 2213. Furthermore, the threaded fastener can be screwed into the second connecting hole 1213 and the first connecting hole 2213 more smoothly, avoiding the need to manually adjust the position of the first connecting piece 121 during the connection process of the threaded fastener. The setting of the abutment portion 222 improves the assembly efficiency of the electronic control box 100 installed on the rear panel 200.

[0071] In some embodiments, referring to Figures 8-10 and 17-20, the connecting side 221 is further provided with a third positioning wall 2212, which can be perpendicular to the rotation axis. The side of the third positioning wall 2212 facing away from the rotation axis is connected to the side of the second positioning wall 2211 near the electrical control box 100 (i.e., the two can connect two adjacent surfaces of the side 221). The first connecting piece 121 includes a connecting portion 1211 and a positioning portion 1212. When the first connecting piece 121 is in the second positioning position, the connecting portion 1211 can abut against the second positioning wall 2211, and the positioning portion 1212 can abut against the third positioning wall 2212. When the connecting portion 1211 slides from the first positioning position to the second positioning position along the second direction Y, the positioning portion 1212 can slide from the third position to the fourth position along the third positioning wall 2212 along the second direction Y. The setting of the positioning portion 1212 enables the connecting side 221 to position the electric control box 100 along a direction parallel to the rotation axis, so that the second connecting hole 1213 can be aligned with the first connecting hole 2213 along a direction parallel to the rotation axis, thereby facilitating the screwing in of the threaded fastener, further improving the installation efficiency of the electric control box 100.

[0072] In some embodiments, referring to Figures 8-10 and 17-18, the electric control box 100 includes a first housing 110, a second housing 120, and a conductive element. The conductive element is disposed within the first housing 110, and the second housing 120 is wrapped around the first housing 110. The second housing 120 includes a first connecting piece 121, and the second positioning structure 130 also includes a second connecting piece 112. The first housing 110 includes the second connecting piece 112. The second connecting piece 112 extends out of the second housing 120 and abuts against a side of the first connecting piece 121 facing away from the second positioning wall 2211. The second connecting piece 112 and the first connecting piece 121 can be connected by threads. Specifically, the second positioning structure 130 includes the first connecting piece 121 and the second connecting piece 112. The first connecting piece 121 is disposed in the second housing 120, and the second connecting piece 112 is disposed in the first housing 110. When the second positioning structure 130 slides from the first positioning position to the second positioning position along the second direction Y, the second connecting piece 112 abuts against the side of the first connecting piece 121 facing away from the second positioning wall 2211. Furthermore, the second connecting piece 112 and the first connecting piece 121 can be connected via threaded fasteners, thereby improving the integrity of the second housing 120 and the first housing 110. Furthermore, the first connecting piece 121 and the second connecting piece 112 can be disposed on the same side of the electrical control box 100, which can more effectively utilize the space within the air conditioner 10 and make the internal structure of the air conditioner 10 more compact. In one embodiment, the second connecting piece 112 has a third connecting hole. When the second positioning structure 130 is in the second positioning position, the third connecting hole is aligned with the second connecting hole 1213, and the second connecting hole 1213 is aligned with the first connecting hole 2213. The threaded fastener is sequentially passed through the third connecting hole, the second connecting hole 1213, and the first connecting hole 2213 and tightened, thereby connecting the second connecting piece 112 and the first connecting piece 121 to the frame 220. This further improves the connection reliability between the electric control box 100 and the rear panel 200.

[0073] To improve the compactness of the various components of the air conditioner 10, in some embodiments, as shown in Figures 3-6, the air conditioner 10 further includes a housing 400. The air supply assembly 300, the rear panel 200, and the electrical control box 100 are all disposed within the housing 400. The housing 400 protects the components disposed therein, facilitating maintenance and repair. At least one end of the first connecting piece 121 along the second direction Y extends beyond the second connecting piece 112. The end of the first connecting piece 121 extending beyond the second connecting piece 112 is bent away from the second positioning wall 2211 to connect to the housing 400. In a specific embodiment, at least one end of the first connecting piece 121 along the second direction Y can protrude beyond the second connecting piece 112 away from the second positioning wall 2211. The end of the first connecting piece 121 protruding beyond the second connecting piece 112 is a bent structure, and this bent structure can connect to the housing 400. When the assembly formed by attaching the electronic control box 100 to the rear panel 200 is assembled to the housing 400, the bent structure of the first connecting piece 121 can abut against the inner wall of the housing 400. In one embodiment, the first connecting piece 121 and the housing 400 can be connected by welding, thereby providing a strong connection to secure the electronic control box 100 and improving the integrity of the air conditioner 10. In another embodiment, the first connecting piece 121 and the housing 400 can be connected by threaded fasteners to facilitate subsequent maintenance and adjustment of the air conditioner 10, thereby increasing the structural flexibility of the air conditioner 10. Connecting the first connecting piece 121 to the housing 400 not only strengthens the connection between the electronic control box 100 and other components outside the rear panel 200, but more importantly, it strengthens the connection between the electronic control box 100 and the entire air conditioner 10. This ensures the stability of the electronic control box 100, thereby guaranteeing the normal operation and service life of the air conditioner 10. At the same time, this design enables the various component structures of the air conditioner 10 to be tightly combined together to form a compact whole, which greatly improves the compactness and integrity of the air conditioner 10.

[0074] To enhance the safety of the air conditioner 10, in some embodiments, as shown in Figures 8-10 and 17-18, the first housing 110 is an injection-molded part, while the second housing 120 is a sheet metal part. To simplify the manufacture of the second housing 120, the first connecting piece 121 (located on the second housing 120) connected to the outer shell 400 is also a sheet metal part. In one embodiment, the portion of the outer shell 400 connected to the first connecting piece 121 can be made of a conductive material (e.g., aluminum alloy, stainless steel, carbon fiber composite material, etc.), and a grounding structure can be provided on the exterior of the outer shell 400, thereby enabling the electrical control box 100 to be grounded through the outer shell 400. In another embodiment, to reduce the difficulty of manufacturing the outer shell 400, the outer shell 400 can be made of a conductive material, and an insulating layer (e.g., resin, silicone rubber, etc.) can be provided on the surface of the outer shell 400. The portion of the outer shell 400 connected to the first connecting piece 121 is not provided with an insulating layer, allowing the electrical control box 100 to be grounded through this portion. Grounding the electric control box 100 can lead the static electricity generated by it into the ground, preventing high voltage from damaging the conductive components inside the electric control box 100, and thus ensuring the safety of the air conditioner. On the other hand, it can also prevent the influence of external electromagnetic interference on the electric control box 100, improve the stability of the operation of the internal circuit system of the electric control box 100, and ensure the integrity of the data of the air conditioner 10. In addition, grounding the electric control box 100 can also provide it with a stable zero potential reference point, providing a good grounding plane for the internal circuit of the electric control box 100, thereby improving the stability and quality of signal transmission. Grounding the electric control box 100 through the housing 400 can save additional space and cost for arranging the grounding structure of the electric control box 100, effectively improving the practicality of the air conditioner 10.

[0075] In some embodiments, referring to Figures 8-10 and 17-18, the frame 220 includes at least two first positioning structures 223 distributed along the second direction Y, and the number of second positioning structures 130 included in the electric control box 100 is the same as the number of first positioning structures 223. Furthermore, each second positioning structure 130 is connected to each first positioning structure 223 in a one-to-one correspondence. The provision of multiple first positioning structures 223 and multiple second positioning structures 130 increases the connection stability of the electric control box 100, preventing the connection between the electric control box 100 and the frame 220 from failing when some of the second positioning structures 130 become loose from the first positioning structures 223, thereby reducing potential risks and malfunctions. Since the space inside the air conditioner 10 is very limited, positioning the protrusion 111 between at least two second positioning structures 130 can fully utilize the space, making the entire structure of the air conditioner 10 more compact and facilitating a reduction in the volume of the air conditioner 10.

[0076] In the technical solution of this application, the rear panel includes a positioning bracket and a frame. The positioning bracket is provided with a slot, and the frame is provided with a first positioning structure. The electronic control box includes a protrusion and a second positioning structure, which is connected to the first positioning structure. Because the protrusion can be inserted into the slot along a second direction, which is perpendicular to the vibration direction of the force generated during motor operation, and the protrusion is configured to be restrained by the slot and disengage from the slot along the first direction, the connection between the electronic control box and the rear panel is ensured to be effective.

[0077] Furthermore, compared to the related art method of using threaded fasteners to secure the electric control box to the positioning bracket, the electric control box in this solution can be connected to the positioning bracket by directly inserting the protrusion into the slot, making installation simpler and more convenient. Specifically, in the related art, when connecting the electric control box and the positioning bracket, the threaded fasteners must be inserted through the positioning bracket and the electric control box in sequence, pointing from the positioning bracket toward the electric control box, and then tightened. However, due to the limited internal space of the air conditioner, this installation process is easily affected by the other internal components of the air conditioner, making installation difficult and labor-intensive.

[0078] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0079] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or", "and / or" or "and / or" appear in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0080] The above are only some preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. All equivalent structural transformations made using the description and drawings of the present application under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
