Related art proposes an air conditioner that integrates the outdoor and indoor units and can be installed on a window. The air conditioner includes a rear panel for mounting a motor and protecting fan blades, as well as an electronic control box for controlling the normal operation of the air conditioner. Conventional technology usually uses bolts to connect the electronic control box to the rear panel. However, since the motor inevitably vibrates during operation, this vibration is transmitted to the rear panel, which may cause the bolts 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 operate normally.

[0068] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed embodiments

[0069] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0070] An air conditioner generally 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 effects of heat transfer and indoor-outdoor gas exchange. In order to reduce costs and facilitate the installation of the air conditioner, in the related art, an air conditioner has been proposed. This 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 components inside both are arranged in the same housing), and this air conditioner can be installed on a window to connect indoors and outdoors, thereby achieving the effects of heat transfer and indoor-outdoor gas exchange. This air conditioner includes a motor, a fan blade, a rear enclosure, an electric control box, etc. The rear enclosure can be used to install the motor and can protect the fan blade to prevent other components from interfering with the rotation of the fan blade. The electric control box is used to control the normal operation of the air conditioner. Usually, bolts are used to connect the electric control box to the rear enclosure. However, since the motor inevitably generates vibration during operation, this vibration transmitted to the rear enclosure may cause the threaded fasteners connecting the electric control box to the rear enclosure to loosen, and further cause the connection between the electric control box and the rear enclosure to fail, resulting in problems such as the air conditioner being unable to be used normally.

[0071] In view of this, please refer to Figures 1 to 20 , the present invention provides an air conditioner 10. Specifically, refer to Figures 1 - 3 , this air conditioner 10 includes a air supply component 300, a positioning bracket 210, a frame body 220, an electric control box 100, etc. The air supply component 300 includes a motor 310 and a fan blade 320. The fan blade 320 can be arranged in the channel of the air conditioner 10 connecting indoors or in the channel of the air conditioner 10 connecting outdoors. The fan blade 320 is connected to the motor 310, and this motor 310 can drive the fan blade 320 to rotate. In one embodiment, the fan blade 320 is driven to rotate so as to drive the air flow to flow towards the heat exchanger. The air flow contacts the heat exchanger so that the heat of the heat exchanger can be transferred to the indoor (or outdoor) through the air flow. The setting of the fan blade 320 can accelerate the air flow, thereby improving the heat exchange efficiency of the heat exchanger. In another embodiment, the fan blade 320 is driven by the motor 310 to rotate to generate an air flow, and this air flow can make the cold air and warm air in the room evenly distributed at each position in the room. In addition, the rotation of the fan blade 320 can drive the air to enter the air conditioner 10 (or drive the air conditioner 10 to discharge the air conditioner 10), thereby realizing the circulation of indoor and outdoor air.

[0072] Refer toFigures 1 - 4 , in some embodiments, the positioning bracket 210 can be connected to the frame body 220 and combined to form the rear panel 200 (in other embodiments, the positioning bracket 210 can be separated from the frame body 220). The positioning bracket 210 can be used to mount the motor 310. The frame body 220 is arranged around the circumferential side of the fan blade 320. The frame body 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 at the same time prevent other components that accidentally enter the rotation range of the fan blade 320 from being damaged when the fan blade 320 rotates. 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 avoiding the indoor temperature being too high or too low. The electric control box 100 can also perform power protection and short-circuit protection on the air conditioner 10, avoiding 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 applicable to different environments and meet different energy consumption requirements at the same time.

[0073] See Figures 3 - 4 , Figure 6 , Figure 10 and Figure 17 , wherein, the positioning bracket 210 is provided with a slot 211, the frame body 220 includes a first positioning structure 223, and the electric control box 100 includes a protrusion 111 and a second positioning structure 130. For the convenience of description, the direction from the motor 310 to the slot 211 is defined as the first direction X, and the first direction X is substantially perpendicular to the rotation axis of the motor 310. Among them, the direction substantially perpendicular to the first direction X is the second direction Y, as Figure 3, the second direction Y is also substantially perpendicular to the rotation axis of the motor 310. It should be noted that, as long as the angle formed between the first direction X and the rotation axis of the motor 310 is within the range of not less than 75 degrees and not more than 105 degrees, it can be considered that the first direction X is substantially perpendicular to the rotation axis of the motor 310. Exemplarily, 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, as long as the angle formed between the second direction Y and the first direction X is within the range of not less than 75 degrees and not more than 105 degrees, it can be considered that the second direction Y is substantially perpendicular to the first direction X. Exemplarily, 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. As long as the angle formed between the second direction Y and the rotation axis of the motor 310 is within the range of not less than 75 degrees and not more than 105 degrees, it can be considered that the second direction Y is substantially perpendicular to the rotation axis of the motor 310. Exemplarily, 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.

[0074] For details, see Figure 4, the protrusion 111 can be inserted into the card slot 211 along the second direction Y, and the second positioning structure 130 can be connected to the first positioning structure 223, so that the electric control box 100 can be quickly connected to the rear panel 200. The rear panel 200 can be used to provide a supporting force for the electric control box 100, so as to prevent the electric control box 100 from colliding with other components inside the air conditioner 10 and being damaged when the air conditioner 10 vibrates or is impacted during transportation and use. The protrusion 111 is configured to be restricted by the card slot 211 to prevent it from disengaging from the card slot 211 along the first direction X, which can prevent the electric control box 100 from being affected by the vibration force generated during the operation of the motor 310 and disengaging from the positioning bracket 210. In other words, when the motor 310 generates vibration, since the installation direction of the protrusion 111 (the protrusion 111 is installed in the card slot 211 along the second direction Y) is perpendicular to the direction in which the vibration force acts on the electric control box 100, the component of the vibration force in the second direction Y is eliminated, which reduces the risk of the electric control box 100 being damaged due to the vibration of the motor 310 and improves the stability of the air conditioner 10. Moreover, as the component of the vibration force in the second direction Y is eliminated, the card slot 211 has a restricting effect on the protrusion 111 along the first direction X, and the protrusion 111 will not be able to disengage from the card slot 211 along the first direction X, thereby reducing the risk of displacement and stress of the protrusion 111 (the electric control box 100) due to the vibration of the motor 310. Further, it ensures the connection effectiveness between the electric control box 100 and the rear panel 200. Specifically, the card slot 211 has a receiving cavity extending along the second direction Y. Along the second direction Y, at least one end of the receiving cavity has a notch 2111, and the protrusion 111 can be inserted into the receiving cavity through the notch 2111. The card slot 211 has a restricting effect on the protrusion 111 along the first direction X, thereby restricting the freedom degree of the electric control box 100 along the first direction X and preventing it from disengaging from the positioning bracket 210 due to the vibration of the motor 310. See Figure 4 And 9. Specifically, the card slot 211 has an inner peripheral wall 2112, and the inner peripheral wall 2112 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 against the inner peripheral wall 2112.

[0075] Exemplarily, the included angle between the first direction X and the rotation axis is 90 degrees, and the included angle between the second direction Y and the first direction X is 75 degrees. When the motor 310 generates vibration, since the component of the vibration force in the second direction Y is small, the component of the vibration force in the second direction Y is much smaller than the force exerted by the electric control box 100 on the rear panel 200 (the self-gravity of the electric control box 100 and the locking force of the first connecting piece 121 fixed to the frame 220 by the threaded fastener, etc.). That is, the vibration force cannot make the protrusion 111 disengage from the card slot 211, thereby ensuring the connection effectiveness of the electric control box 100.

[0076] In the present invention, since the protrusion 111 can be inserted into the card slot 211 along the second direction Y, and the second direction Y is perpendicular to the direction of the vibration force generated during the operation of the motor 310, and the protrusion 111 is configured to be restricted by the card slot 211 to prevent it from disengaging from the card slot 211 along the first direction X, the connection effectiveness between the electric control box 100 and the rear panel 200 is ensured. Further, the electric control box 100 can be connected to the positioning bracket 210 by directly inserting the protrusion 111 into the card slot 211, making the installation of the electric control box 100 simpler and more convenient. Compared with the installation method in the related art, where the electric control box 100 is connected to the positioning bracket 210 by using threaded fasteners (the threaded fasteners are sequentially inserted through the positioning bracket 210 and the electric control box 100 and tightened in the direction from the positioning bracket 210 to the electric control box 100, and due to the limited internal space of the air conditioner 10, it is not conducive to the installation of the threaded fasteners), the mutual cooperation between the protrusion 111 and the card slot 211 can install the electric control box 100 on the positioning bracket 210 within a limited space, avoiding the influence of other component structures inside the air conditioner 10 on the electric control box 100 during the installation process, reducing the installation difficulty of the electric control box 100, and at the same time reducing the labor cost.

[0077] In some embodiments, please refer to Figure 13 , the card slot 211 is not provided with a through hole along the first direction X and away from the motor 310. The protrusion 111 includes a first engaging portion 1112 and a second engaging portion 1113. One end of the first engaging portion 1112 along the first direction X and away from the motor 310 is connected to the main body of the electric control box 100, and the other end is connected to the second engaging portion 1113. The second engaging portion 1113 extends along the second direction Y, and the second engaging portion 1113 can be inserted into the receiving cavity through the notch 2111 of the receiving cavity along the second direction Y. The first engaging portion 1112 and the second engaging portion 1113 together form a structure similar to an "L" shape. In other embodiments, please refer to Figure 4 , Figure 8 and Figure 9, the side of the card slot 211 facing away from the motor 310 can also be provided with a through hole, and one end of the protrusion 111 can extend out of the card slot 211 along the first direction X. Specifically, the accommodation cavity penetrates through the card slot 211 along the first direction X and the side facing away from the motor 310. For the convenience of description, it is defined that an opening is provided on the side of the card slot 211 along the first direction X and facing away from the motor 310, and this opening communicates with the slot opening 2111 and the accommodation cavity. One end of the protrusion 111 along the first direction X is connected to the electronic control box 100, and the other end can be inserted into the accommodation cavity along the second direction Y through the slot opening 2111. During this process, the end of the protrusion 111 close to the electronic control box 100 can move within the opening. The setting of the opening makes the structure of the protrusion 111 simpler. Moreover, when the motor 310 vibrates, the force received by the junction part of the protrusion 111 and the electronic control box 100 is along the first direction X, and only a relatively small shear force is received at this part. 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 further reduce the maintenance cost of the air conditioner 10.

[0078] To effectively prevent the electronic control box 100 from disengaging from the positioning bracket 210 along the first direction X, in some embodiments, please refer to Figures 1 - 4 , and Figure 9 、 Figure 14 and Figure 15For ease of description, the 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 decreases gradually or 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 disengage from the slot 211 along the first direction X. That is, in one embodiment, the width of the slot 211 decreases linearly along the first direction X. It should be noted that this linearity can be either straight or curved. That is, the change in the width of the slot 211 along the third direction Z along the first direction X can be uniform or non-uniform. Specifically, when the projection plane is perpendicular to the second direction Y, the outline of the projection of 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 width of the card slot 211 along the third direction Z decreases at a specific interval or in a "step-like" direction. Specifically, the projection plane is perpendicular to the second direction Y, and the contour shape of the projection formed by the card slot 211 on the projection plane can be similar to "∠", or similar to "┴", or similar to "└". Since the slot width of the card slot 211 (the dimension of the card slot 211 in the third direction Z) decreases along the first direction X, after the protrusion 111 is inserted into the card slot 211, the card slot 211 can increase the restraint 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 card slot 211, preventing the protrusion 111 from detaching from the card slot 211 along the first direction X under 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.

[0079] In order to improve the supporting effect of the positioning bracket 210 on the electric control box 100, in some embodiments, please refer to Figure 4 、 Figure 8 as well as Figure 9, the positioning bracket 210 includes a positioning boss 212 which has a first positioning wall 2121 facing away from the motor 310. After the protrusion 111 is inserted into the card slot 211, one side of the electric control box 100 can abut against the first positioning wall 2121. Since the electric control box 100 is also connected to the first positioning structure 223 (located on the frame body 220) through the second positioning structure 130, and the frame body 220 is connected to the positioning bracket 210, thus, the setting of the positioning boss 212 can further enhance the connection stability between the electric control box 100 and the positioning bracket 210 and can provide an additional supporting force for the electric control box 100. In some other embodiments, the positioning boss 212 can also be provided on the electric control box 100. Specifically, the positioning boss 212 can be provided on the side of the electric control box 100 close to the motor 310 and protrudes relative to the surface of the electric control box 100. The positioning bracket 210 is provided with a positioning groove. When the protrusion 111 is inserted into the card slot 211 along the second direction Y, the positioning boss 212 can be clamped in the positioning groove. After the electric control box 100 is installed on the rear panel 200, the setting of the positioning groove and the positioning boss 212 can limit the movement of the electric control box 100 along the second direction Y, and the positioning boss 212 can provide an additional supporting force for the electric control box 100, thereby improving the installation stability of the electric control box 100.

[0080] In some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 , the card slot 211 has a slot opening 2111 located on one side along the second direction Y. Along the second direction Y, the first positioning wall 2121 is provided on the side of the card slot 211 facing away from the slot opening 2111. Specifically, after the protrusion 111 is inserted into the card slot 211 through the slot opening 2111, one side of the electric control box 100 can abut against the first positioning wall 2121. When the electric control box 100 moves due to the vibration of the motor 310, the first positioning wall 2121 and the card slot 211 can provide a resistance force for the electric control box 100 in a direction opposite to the direction of the vibration force, so that the electric control box 100 can be firmly connected to the rear panel 200 and prevent the protrusion 111 from disengaging from the card slot 211 and causing the connection between the electric control box 100 and the positioning bracket 210 to fail. In some other embodiments, please refer to Figure 4 , Figure 8 and Figure 9, the first positioning wall 2121 is located on the side of the card slot 211 along the first direction X and away from the motor 310. In one embodiment, the first positioning wall 2121 is farther from the motor 310 than the card slot 211, that is, the distance from the first positioning wall 2121 to the rotation axis is greater than the distance from the side of the card slot 211 along the first direction X and away from the motor 310 to the rotation axis. After the protrusion 111 is inserted into the card slot 211 through the slot opening 2111, one side of the electronic control box 100 can abut against the first positioning wall 2121, and the first positioning wall 2121 can provide an additional supporting force to the electronic control box 100, further enhancing the connection stability between the electronic control box 100 and the positioning bracket 210.

[0081] To prevent the vibration of the motor 310 from being transmitted to the electronic control box 100 through the card slot 211 and causing damage to the conductive components inside the electronic control box 100, in some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 , the protrusion 111 has an outer peripheral wall 1111, which is arranged around the protrusion 111 along the axis parallel to the second direction Y, and the outer peripheral wall 1111 is spaced from the groove wall of the card slot 211. That is, after the protrusion 111 is inserted into the card slot 211, there is a gap between the outer peripheral wall 1111 of the protrusion 111 and the groove wall of the card slot 211. When the motor 310 vibrates, the structures connected to the motor 310 will be affected by this vibration. Since the outer peripheral wall 1111 of the protrusion 111 is spaced from the groove wall of the card slot 211, when the vibration of the motor 310 is transmitted to the card slot 211, due to the existence of the gap between the outer peripheral wall 1111 and the groove wall, the vibration generated by the motor 310 is isolated by this gap (the setting of the gap can reduce the efficiency of the vibration transmitted from the motor 310 to the electronic control box 100 through the card slot 211 when the motor 310 vibrates, and even interrupt the transmission of the vibration to the electronic control box 100), thus effectively protecting the electronic control box 100 and its internal components and reducing the risk of connection failure between the conductive components inside the electronic control box 100. In one embodiment, in order to effectively reduce the influence of the vibration generated by the motor 310 on the electronic control box 100, a buffer component can be arranged between the outer peripheral wall 1111 of the protrusion 111 and the groove wall of the card slot 211. The buffer component can be sponge, rubber, polyurethane foam, etc. In some other embodiments, the outer peripheral wall 1111 of the protrusion 111 abuts against the groove wall of the card slot 211 (it can be that one end of the protrusion 111 close to the motor 310 abuts against the groove wall of the card slot 211, or the side wall of the protrusion 111 away from the motor 310 abuts against the groove wall of the card slot 211, or the groove walls of the card slot 211 all abut against the outer peripheral wall 1111 of the protrusion 111), so as to firmly install the electronic control box 100 on the positioning bracket 210 and improve the integrity.

[0082] In order to effectively protect the components inside the electric control box 100, in some embodiments, please refer to Figures 16 - 18 , the electric control box 100 includes a first housing 110, a second housing 120, and a conductive element. The conductive element is disposed inside the first housing 110, and the second housing 120 is wrapped outside the first housing 110. The strength and durability of the material used for the second housing 120 can be higher than those of the material used for the first housing 110. Thus, the second housing 120 can protect the first housing 110 and the conductive element, preventing the first housing 110 from being deformed or even damaged by external forces, which may affect the normal operation of the conductive element. The conductive element can be a component that can conduct electricity, or a component that can conduct current during operation, or a combination of both. Specifically, the conductive element can be an inductor, a capacitor, a resistor, a connector, a wire, etc., or an aggregate of these components. The material of the second housing 120 can be metal, and the first housing 110 can be made of plastic. The second housing 120 can be formed by sheet metal stamping, and the first housing 110 can be formed by injection molding. In one usage scenario, when a fire occurs, the second housing 120 can protect the first housing 110, preventing the fire outside the second housing 120 from spreading to the first housing 110 and causing damage to the conductive elements inside the electric control box 100 (the electric control box 100 is one of the very important components in the air conditioner 10, responsible for controlling various functions and operations of the air conditioner 10, and can ensure the performance and reliability of the air conditioner 10). In another usage scenario, when a fire breaks out inside the first housing 110, the second housing 120 can isolate the fire, preventing the fire from spreading outside the second housing 120 and affecting other components of the air conditioner 10, or even threatening the life and property safety of users. In addition, since the second housing 120 is made of metal material, it can play an electromagnetic shielding role for the conductive elements and other components disposed inside the first housing 110, effectively reducing external electromagnetic interference and preventing it from affecting the normal operation of the conductive elements, thereby improving the anti-interference ability of the electric control box 100. The first housing 110 is made of plastic, which has excellent insulation performance and can provide insulation protection for the conductive elements.

[0083] Please refer to Figures 16 - 18, the second housing 120 is provided with an opening. The first housing 110 includes a protrusion 111 that can pass through the opening and be inserted into the card 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 is integrally injection molded with the first housing 110. Arranging 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. Moreover, arranging the protrusion 111 on the first housing 110 can simplify the production process and reduce the production cost (when the protrusion 111 is arranged on the first housing 110, the protrusion 111 can be integrally injection molded with the first housing 110). In another embodiment, the protrusion 111 can also be arranged on the second housing 120. The second housing 120 is made of a metal material. To improve the connection reliability between the protrusion 111 and the second housing 120, the protrusion 111 can also be made of a metal material. The second housing 120 can be formed by sheet metal stamping, and the protrusion 111 can be connected to the second housing 120 by means such as welding. Arranging the protrusion 111 on the second housing 120 can reduce the mold cost of producing the first housing 110.

[0084] In some embodiments, please refer to Figures 5 - 12The frame 220 includes a connecting side 221. Along the first direction X, the connecting side 221 is located on the side of the slot 211 away from the motor 310. The connecting side 221 has a second positioning wall 2211 that is away from the rotation axis. The first positioning structure 223 includes a first connecting hole 2213 provided on the second positioning wall 2211. The second positioning structure 130 includes a first connecting piece 121. The first connecting piece 121 can abut against the second positioning wall 2211 and be threadedly connected to the first connecting hole 2213. Specifically, the first connecting piece 121 has a second connecting hole 1213 that passes 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.

[0085] In the specific implementation, please refer to Figures 5 - 12, the first connecting piece 121 has a first positioning position and a second positioning position that abut 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 the pre-inserted card slot 211 state). At this time, the positions of the first connecting hole 2213 and the second connecting hole 1213 are offset. When the first connecting piece 121 is in the second positioning position, the protrusion 111 is inside the card slot 211 (that is, the protrusion 111 has been inserted into the card slot 211). At this time, the first connecting hole 2213 is aligned with the second connecting hole 1213. The threaded fastener is sequentially inserted into the first connecting hole 2213 and the second connecting hole 1213 and tightened, so that the first connecting piece 121 is connected to the frame body 220. By inserting the protrusion 111 into the card slot 211 and at the same time connecting the first connecting piece 121 to the connecting side 221 by using a threaded fastener, the electronic control box 100 can be conveniently connected or detached from the rear panel 200. In some other embodiments, the extending direction of the card slot 211 may also be along the third direction Z, and the protrusion 111 can be inserted into the card 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 from the first positioning position to the second positioning position along the third direction Z with the protrusion 111. When the first connecting piece 121 is located at the first positioning position, the protrusion 111 is outside the card slot 211, and the position of the first connecting hole 2213 is offset from the position of the second connecting hole 1213. When the first connecting piece 121 is in the second positioning position, the protrusion 111 is inside the card slot 211, the first connecting hole 2213 is aligned with the second connecting hole 1213, and the threaded fastener is sequentially inserted into the first connecting hole 2213 and the second connecting hole 1213 and tightened, so that the first connecting piece 121 is connected to the frame body 220.

[0086] In order to ensure that the second connecting hole 1213 can be accurately aligned with the first connecting hole 2213 when the first connecting piece 121 is in the second positioning position, in some embodiments, please refer to Figures 5 - 12, the connecting side edge 221 further includes an abutting portion 222, and this abutting portion 222 is located on the side of the second positioning position away from the first positioning position. The first connecting piece 121 is configured to be able to abut against the abutting 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 abutting portion 222 provides a certain binding force for the first connecting piece 121, and the first connecting piece 121 can naturally abut against the abutting portion 222, so that the second connecting hole 1213 can be quickly aligned with the first connecting hole 2213. Further, the threaded fastener can be screwed into the second connecting hole 1213 and the first connecting hole 2213 more smoothly, avoiding manually adjusting the position of the first connecting piece 121 during the connection process of the threaded fastener. The setting of the abutting portion 222 improves the assembly efficiency of the electric control box 100 installed on the rear wall panel 200.

[0087] In some embodiments, please refer to Figures 8 - 10 and Figures 17 - 20 , the connecting side edge 221 is further provided with a third positioning wall 2212, and this third positioning wall 2212 can be perpendicular to the rotation axis. The side edge of the third positioning wall 2212 away from the rotation axis is connected to the side edge of the second positioning wall 2211 close to the electric control box 100 (that is, the two can be two adjacent surfaces on the connecting side edge 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 at the same time 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 second direction Y on the third positioning wall 2212. The setting of the positioning portion 1212 can position the electric control box 100 by the connecting side edge 221 along the direction parallel to the rotation axis, so that the second connecting hole 1213 can be aligned with the first connecting hole 2213 along the direction parallel to the rotation axis, thus facilitating the screwing of the threaded fastener. Further, the installation efficiency of the electric control box 100 is improved.

[0088] In some embodiments, please refer to Figures 8 - 10 and Figures 17 - 18The electric control box 100 includes a first shell 110, a second shell 120, and a conductive element. The conductive element is disposed within the first shell 110, and the second shell 120 is wrapped around the outside of the first shell 110. The second shell 120 includes a first connecting piece 121, and the second positioning structure 130 also includes a second connecting piece 112. The first shell 110 includes the second connecting piece 112. The second connecting piece 112 extends out of the second shell 120 and abuts against the 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 a first connecting piece 121 and a second connecting piece 112. The first connecting piece 121 is disposed in the second shell 120, and the second connecting piece 112 is disposed in the first shell 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.

[0089] In order to improve the installation compactness of each structure of the air conditioner 10, in some embodiments, please refer to Figures 3 - 6, the air conditioner 10 further includes a housing 400. The air supply component 300, the rear panel 200, and the electric control box 100 are all disposed within the housing 400. The housing 400 can protect the components disposed therein, which is conducive to maintenance and repair. At least one end of the first connecting piece 121 extends beyond the second connecting piece 112 along the second direction Y, and 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 be connected 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 in a direction away from the second positioning wall 2211, and the end of the first connecting piece 121 protruding beyond the second connecting piece 112 is a bent structure, and this bent structure can be connected to the housing 400. When assembling the assembly formed after installing the electric control box 100 on the rear panel 200 into 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, so as to provide a strong connection strength for the fixation of the electric control box 100, thereby improving the integrity of the air conditioner 10. In another embodiment, the first connecting piece 121 and the housing 400 can also be connected by threaded fasteners, which is convenient for the later maintenance and adjustment of the air conditioner 10 and improves the structural flexibility of the air conditioner 10. By connecting the first connecting piece 121 to the housing 400, not only the connection between the electric control box 100 and other component structures other than the rear panel 200 is increased, but more importantly, the connection strength between the electric control box 100 and the entire air conditioner 10 is enhanced. This ensures the stability of the electric 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 closely combined together to form a compact whole, greatly improving the compactness and integrity of the air conditioner 10.

[0090] To improve the safety of the air conditioner 10, in some embodiments, please refer to Figures 8 - 10 and Figures 17 - 18, the first housing 110 is made of an injection molded part, and the second housing 120 is made of a sheet metal part. To simplify the manufacture of the second housing 120, the first connecting piece 121 (provided on the second housing 120) connected to the outer housing 400 is also made of sheet metal. In one embodiment, the part of the outer housing 400 connected to the first connecting piece 121 can be made of a conductive material (such as aluminum alloy, stainless steel, carbon fiber composite material, etc.), and a grounding structure can be provided outside the outer housing 400, so that the electric control box 100 can be grounded through the outer housing 400. In another embodiment, to reduce the processing difficulty of the outer housing 400, the outer housing 400 is made of a conductive material, and an insulating layer (such as resin, silicone rubber, etc.) can be provided on the surface of the outer housing 400, and the part of the outer housing 400 connected to the first connecting piece 121 is not provided with an insulating layer, and the electric control box 100 can be grounded through this part. Grounding the electric control box 100 can introduce the static electricity generated by it into the ground, avoid damage to the conductive components inside the electric control box 100 caused by high voltage, and ensure 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 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 a stable zero potential reference point for it, provide a good grounding plane for the internal circuit of the electric control box 100, and thus improve the stability and quality of signal transmission. Grounding the electric control box 100 through the outer housing 400 can save the space and cost of arranging an additional grounding structure for the electric control box 100, and effectively improve the practicability of the air conditioner 10.

[0091] In some embodiments, please refer to Figures 8 - 10 and Figures 17 - 18 , the frame body 220 includes at least two first positioning structures 223 distributed along the second direction Y, and the number of the second positioning structures 130 included in the electric control box 100 is the same as the number of the first positioning structures 223. Moreover, each of the second positioning structures 130 is connected to each of the first positioning structures 223 in a one-to-one correspondence. The arrangement of the multiple first positioning structures 223 and the multiple second positioning structures 130 increases the connection stability of the electric control box 100, avoids the connection failure between the electric control box 100 and the frame body 220 when some of the second positioning structures 130 are loose from the first positioning structures 223, and reduces potential risks and failures. Since the space inside the air conditioner 10 is very limited, setting the protrusion 111 between at least two second positioning structures 130 can make full use of the space, make the whole structure of the air conditioner 10 more compact, and is beneficial to reducing the volume of the air conditioner 10. It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative position relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0092] In addition, if descriptions such as "first" and "second" are involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.
