[0058] Wall-mounted indoor units contain a large number of wires and signal lines. Most wall-mounted indoor units on the market use a wiring scheme that connects multiple wire / signal line terminals to the wiring holes on the control box 20 one by one. This is not only cumbersome, difficult to connect, and inefficient, but also prone to problems such as wire pressing and jamming due to the large number of wires involved, resulting in a low pass rate.

[0059] In view of this, the present invention provides an air conditioner, the air conditioner including a wall-mounted indoor unit 100, Figures 1 to 18 This is a specific embodiment of the wall-mounted indoor unit 100 proposed in this invention.

[0060] See Figure 1 and Figure 2The wall-mounted indoor unit 100 includes a housing 10, an electrical control box 20, a guide portion 31, and a mating portion 32. The housing 10 has an electrical control box mounting position, and an integrated connection terminal 13 is provided on the housing 10 corresponding to the electrical control box mounting position. A mating terminal 22 is provided on the electrical control box 20 corresponding to the integrated connection terminal 13. The guide portion 31 and the mating portion 32 are respectively disposed on the electrical control box 20 and the housing. When the electrical control box 20 is installed in the electrical control box mounting position, the guide portion 31 and the mating portion 32 are mutually positioned and mated so that the mating terminal 22 and the integrated connection terminal 13 are mutually positioned.

[0061] In the technical solution of this invention, by providing an integrated connection terminal 13 on the casing 10, multiple wiring structures of the wall-mounted indoor unit 100, such as the electric auxiliary heating wiring, grounding structure, pipe temperature sensor wiring part, and motor wiring part, are integrated onto a single terminal. By electrically connecting the control box 20 to the docking terminal 22, wiring of multiple wiring structures can be achieved simply by connecting the integrated connection terminal 13 to the docking terminal 22. By optimizing the positions of the integrated connection terminal 13 and the docking terminal 22, the docking terminal 22 can be connected to the integrated connection terminal 13 when the control box 20 is installed in its mounting position. In other words, the structural design of this invention allows for easy installation of the indoor unit by first assembling the control box 20 and then connecting the control box 20 to the integrated connection terminal 13. Once the box 20 is installed at the corresponding position on the housing 10, multiple wiring structures can be connected to the control box 20 via integrated connection terminals 13 and mating terminals 22. This simplifies the cumbersome wiring and disassembly process, improving production efficiency. Simultaneously, matching guide parts 31 and mating parts 32 are provided on the control box 20 and the housing. When mating the integrated connection terminals 13 and 22, the guide parts 31 and 32 are positioned to accurately and quickly connect them, ensuring high efficiency, preventing misalignment, and maintaining stable quality. This wiring structure can be achieved through fully intelligent and automated production during assembly, not only increasing production capacity but also reducing costs, thus enhancing the market competitiveness of the indoor unit.

[0062] Specifically, the housing 10 forms a cavity for installing components such as the electrical control box 20, the fan assembly (not shown), the electric auxiliary heating component (not shown), and the motor (not shown). The housing 10 is generally cylindrical. In actual manufacturing, the housing 10 is typically assembled from multiple shell structures. For example, in this embodiment, the housing 10 includes a chassis, a front frame, and a panel. The chassis is used to mount to a wall, the front frame is mounted on the chassis, and the front frame forms a mounting groove 212 with an opening on one side. The panel covers the opening side of the front frame, and the front frame and panel together enclose the cavity. The electrical control box 20 is located within the cavity and is detachably connected to the housing 10. The specific detachable installation method is not limited. For ease of description, the orientation of the housing 10 is defined herein; specifically, refer to [reference needed]. Figure 1 and Figure 2 With the panel facing forward, the air outlet of the wall-mounted indoor unit 100 faces downward, and the electrical control box 20 is installed near the right end plate of the housing 10, that is, in this article, the electrical control box is installed near the right end plate of the housing 10.

[0063] See Figure 4 , Figure 14 and Figure 16 The integrated connection terminal 13 is mounted on the housing 10 and is used for simultaneous connection of multiple wiring structures, such as power supply auxiliary heating wiring, grounding structure, pipe temperature sensor wiring section, and motor wiring section. The specific implementation of the integrated connection terminal 13 is not limited. For example, the integrated connection terminal 13 can be designed as a single unit, with multiple connection terminal holes 1301 designed on it. These multiple connection terminal holes 1301 are used to insert terminals of multiple wiring structures one-to-one. The multiple connection terminal holes 1301 can be arranged in a matrix or side-by-side. For details, please refer to [reference needed]. Figure 15 and Figure 17In this embodiment, the integrated connection terminal 13 has multiple connection terminal holes 1301 extending through its two opposite ends. The multiple connection terminal holes 1301 are distributed in a straight line at intervals. One end of each connection terminal hole 1301 forms a plug interface for terminal insertion, and the other end forms a contact port. The connection end of the terminal inserted into the connection terminal hole 1301 contacts the docking terminal 22 through the contact port. With this design, during assembly, it is only necessary to insert the terminals of each wiring structure into the plug interface to complete the wiring of multiple wiring structures. The docking is simple and convenient. Since the integrated connection terminal 13 is installed on the housing 10, by adjusting the position of the integrated connection terminal 13 and grouping the multiple wiring structures according to their respective positions to connect to different integrated connection terminals 13, the complex wiring can be neatly arranged. Even if multiple terminals are plugged in, the complex wiring can be neatly fixed on the inner wall of the housing 10, and problems with wire pressing and jamming are not easy to occur. When assembling the electrical control box 20, only the integrated connection terminal 13 docks with the electrical control box 20, avoiding interference from the messy wiring. The integrated connection terminal 13 can also be designed as a separate structure. Specifically, the integrated connection terminal 13 is composed of multiple integrated connection terminal units 130, see reference. Figure 17 and Figure 18 In this embodiment, the integrated connection terminal 13 is composed of two integrated connection terminal units 130 arranged side by side. Each integrated connection terminal unit 130 is designed with multiple connection terminal holes 1301. The two integrated connection terminal units 130 are connected to a docking terminal 22. In this way, it can not only adapt to complex line distribution and wiring structure distribution, and design integrated connection terminals 13 with appropriate shape and position, but also better adapt to the structure of the setting position of the integrated connection terminal 13 and make adjustments according to the structure of the setting position.

[0064] See Figure 5 , Figure 7 and Figure 11The mating terminal 22 is mounted on the electrical control box 20 for mating with the integrated connection terminal 13. Therefore, in terms of position, when the electrical control box 20 is installed in the electrical control box mounting position, the integrated connection terminal 13 and the mating terminal 22 should be opposite each other. Furthermore, for ease of assembly, when the electrical control box 20 is installed in the electrical control box mounting position, the integrated connection terminal 13 and the mating terminal 22 are preferably arranged opposite each other in the installation direction of the electrical control box 20. This way, when the electrical control box 20 is installed in the electrical control box mounting position along the installation direction, the mating terminal 22 can remain opposite to the integrated connection terminal 13 for easy mating. For example, in one embodiment, the electrical control box 20 is installed onto the chassis along the depth direction (from front to back) of the mounting groove 212. In this embodiment, the integrated connection terminal 13 is located on the front side of the chassis, and the mating terminal 22 is located on the rear side of the electrical control box 20 and corresponds to the integrated connection terminal 13. Thus, when the electrical control box 20 is pressed against the chassis in a front-to-back direction, the mating terminal 22 can mate with the integrated connection terminal 13. For ease of description, the installation direction of the electrical control box 20 is defined as the first direction. For example, in this embodiment, the first direction is from front to back. Figure 1 In another embodiment shown, the electrical control box 20 is installed on the chassis from bottom to top, so the first direction is from bottom to top. In this embodiment, the integrated connection terminal 13 and the docking terminal 22 are arranged opposite each other in the vertical direction.

[0065] Furthermore, the specific implementation of the mating terminal 22 is not limited. For example, mating terminal holes 2201 can be designed on the mating terminal 22. The number of mating terminal holes 2201 depends on the number of integrated connection terminal units 130, and the two are set in a one-to-one correspondence. For example, see [reference]. Figure 2 , Figure 8 and Figure 13 The electrical control box 20 is equipped with a circuit board, which has wiring terminals for the electrical control box 20 connected to it. In this embodiment, the mating terminal 22 has two mating terminal holes 2201 that penetrate its two opposite ends. The integrated connecting terminal 13 and the wiring terminal of the electrical control box 20 are inserted into the openings at both ends of the mating terminal hole 2201 respectively, so as to connect accordingly in the mating terminal hole 2201 and achieve mating. This mating method has good connection stability.

[0066] To enable the integrated connection terminal 13 and the mating terminal 22 to mate quickly and accurately, the present invention further provides a guide portion 31 and a mating portion 32. The guide portion 31 and the mating portion 32 are mutually matched and corresponding in both position and structure. Thus, when the electrical control box 20 is installed in the electrical control box mounting position, the guide portion 31 and the mating portion 32 are mutually positioned and mated, thereby achieving pre-positioning and guiding functions, allowing the mating terminal 22 and the integrated connection terminal 13 to be quickly and accurately positioned relative to each other. The specific location of the guide portion 31 and the mating portion 32 is not limited in the present invention. Specifically, in some embodiments, the guide portion 31 and the mating portion 32 are respectively disposed on the housing 10 and the mating terminal 22; in another embodiment, the guide portion 31 and the mating portion 32 are respectively disposed on the housing 10 and the electrical control box 2020.

[0067] The guide part 31 and the mating part 32 can be implemented in various ways, and the present invention does not limit them.

[0068] See Figure 5 , Figure 8 and Figure 9 In this embodiment, the guide portion 31 is configured as a guide post 311, which extends along a first direction. The mating portion 32 is configured as a guide hole 321 that mates with the guide post 311. The guide post 311 and the guide hole 321 are arranged opposite to each other. When the control box 20 is installed in the control box mounting position, the guide post 311 can be inserted into the guide hole 321, thereby achieving guidance and pre-positioning of the control box 20. Specifically, with Figure 8 Taking the illustrated embodiment as an example, in this embodiment, one end of the guide post 311 is disposed at the docking terminal 22, and the other end extends away from the docking terminal 22 along the first direction. The other end of the guide post 311 is spaced apart from the docking terminal 22. The guide hole 321 is formed in the housing 10 and is a through hole. When the electrical control box 20 is installed in the electrical control box mounting position, the guide post 311 can pass through the guide hole 321 to achieve guidance and positioning. The size of the guide hole 321 is based on the thickness of the guide post 311 and can be designed to be just the size for the guide post 311 to pass through, so as to avoid the guide post 311 being misaligned when inserted.

[0069] See Figure 3 and Figure 5 In this embodiment, the guide portion 31 is a slide rail 312 provided on the housing 10, and the slide rail 312 extends along the first direction. The mating portion 32 is a guide block 322 provided on the outer wall of the electrical control box 20, and the guide block 322 is slidably engaged with the slide rail 312. Specifically, as shown... Figure 3As shown, the slide rail 312 is formed inside the housing 10 and extends along the first direction. The guide block 322 is disposed inside the slide rail 312 and can slide along the slide rail 312. The guide block 322 is disposed on the rear side of the electrical control box 20. Thus, when installing the electrical control box 20, it is only necessary to insert the guide block 322 into the slide rail 312 and then push the electrical control box 20. By utilizing the sliding cooperation between the guide block 322 and the slide rail 312, the electrical control box 20 can be quickly and accurately pushed along the first direction and accurately positioned in the electrical control box mounting position. This helps the integrated connection terminal 13 and the docking terminal 22 to better dock and position.

[0070] Furthermore, a section of the slide rail 312 away from its inlet end is formed within the housing 10, while the inlet end of the slide rail 312 penetrates the inner wall of the housing 10 to form an opening 3121; the guide block 322 includes a seat 3221 and a fastener 3222, one end of the seat 3221 is disposed on the outer wall of the electrical control box 20, and the other end extends into the slide rail 312 through the opening 3121, and the fastener 3222 is disposed at the other end of the seat 3221 and extends along... Extending in the first direction, when the electrical control box 20 is installed in the electrical control box mounting position, the fastener 3222 engages with the edge of the opening 3121. In this way, the guide block 322 and the slide rail 312 can be used to accurately position the electrical control box during installation, and the fastener 3222 and the edge of the opening 3121 can be used to fix the electrical control box 20 in that position when it slides to the electrical control box mounting position.

[0071] One or more guide parts 31 and mating parts 32 can be provided. In some embodiments, the wall-mounted indoor unit 100 includes multiple guide parts 31 and multiple mating parts 32. The multiple mating parts 32 correspond one-to-one with the multiple guide parts 31, that is, each guide part 31 is provided with one mating part 32. By providing multiple guide parts 31 and multiple mating parts 32, the mutual positioning of the docking terminal 22 and the integrated connection terminal 13 can be made more accurate and stable through the mutual cooperation of multiple sets of guide parts 31 and mating parts 32.

[0072] Furthermore, the multiple guide portions 31 are preferably centrally symmetrically distributed, thereby enabling even positioning of the mating terminals 22. Figure 8Taking the illustrated embodiment as an example, in this embodiment, the guide portion 31 is disposed on the outer wall of the docking terminal 22 and is configured as a guide post 311. The docking terminal 22 has a first side and a second side arranged opposite to each other. Two guide portions 31 are provided, one on the first side and the other on the second side. Correspondingly, two mating portions 32 are also provided, with each mating portion 32 corresponding to one guide portion 31. Thus, both sides of the docking terminal 22 can be pre-positioned through the mutual cooperation of the guide portions 31 and the mating portions 32, which helps to better position the docking terminal 22 and the integrated connecting terminal 13, enabling them to dock more accurately. Furthermore, compared to three or more guide portions, two oppositely arranged guide portions 31 can ensure balanced positioning of the docking terminal 22, reduce the number of guide portions 31, simplify the structure, and reduce manufacturing difficulty.

[0073] The mating terminal 22 is installed on the electrical control box 20, and there are several specific installation methods. The electrical control box 20 includes a box body 21, a box cover (not shown in the figure), and a circuit board. The box body 21 forms a cavity with one open end. The circuit board is placed inside the cavity. The box cover closes onto the open end of the box body 21 to cover the cavity. See reference. Figure 10 , Figure 12 and Figure 13 In one embodiment, the box body 21 has a mounting hole 211 on its wall. A mating terminal 22 is inserted into the mounting hole 211. One end of the mating terminal 22 extends into the box body 21 and is electrically connected to the circuit board, while the other end protrudes outside the box body 21. The mating terminal hole 2201 of the mating terminal 22 connects the inside and outside of the box body 21. During assembly, the mating terminal 22 is simply inserted into the mounting hole 211. Furthermore, to fix the mating terminal 22 and prevent it from falling off, a first snap-fit ​​part 2231 is provided on the outer wall of the mating terminal 22. At the same time, a first mating part that cooperates with the first snap-fit ​​part 2231 is provided on the box body 21. Thus, when the mating terminal 22 is installed in the mounting hole 211 along the extension direction of the mating terminal hole 2201 (i.e., the thickness direction of the box wall), the first snap-fit ​​part 2231 and the first mating part are engaged, thereby preventing the mating terminal 22 from falling out of the mounting hole 211. Specifically, the first latching part 2231 is a latching protrusion 1331a, and the edge of the mounting hole 211 constitutes the first mating part. When the mating terminal 22 is installed in the mounting hole 211, the latching protrusion 1331a is located inside the housing 21 and abuts against the edge of the mounting hole 211, thereby preventing the mating terminal 22 from disengaging from the mounting hole 211 in the direction from inside the housing 21 to outside the housing 21.

[0074] With the wall-mounted indoor unit 100 equipped with a first latching part 2231 and a first mating part, to further ensure the fixing effect of the docking terminal 22, the box wall of the housing 21 is also provided with a mounting groove 212. One end of the mounting groove 212 communicates with the mounting hole 211, and the other end passes through the opening end of the housing 21. A pressing member 23 is installed in the mounting groove 212. When the docking terminal 22 is installed in the mounting hole 211, the pressing member 23 abuts against the box cover and the docking terminal 22. Specifically, refer to Figure 6 and Figure 11 The box wall is provided with a mounting groove 212 extending in the front-to-back direction. The mounting groove 212 is a through groove that penetrates the box wall and communicates with the mounting hole 211. The pressing member 23 is a block extending in the front-to-back direction. The pressing member 23 is slidably installed in the mounting groove 212. When the box cover is closed, the front end of the pressing member 23 abuts against the box cover and the rear end abuts against the mating terminal 22 inserted in the mounting hole 211. Thus, by transmitting the pressure applied by the box cover to the mating terminal 22, it plays the role of fixing the mating terminal 22. Furthermore, the pressing member 23 has an inner end that extends into the box body 21. The inner end of the pressing member 23 extends laterally to form a stop portion. The stop portion protrudes from the side wall of the pressing member 23 in the width direction. When the pressing member 23 is installed in the mounting groove 212, the stop portion is located inside the box body 21 and abuts against the inner side of the box wall to restrict the pressing member 23 from disengaging from the mounting groove 212 in the direction from inside the box body 21 to outside the box body 21.

[0075] Furthermore, a first guide structure is provided on the outer wall of the docking terminal 22, and a first mating structure adapted to the first guide structure is provided on the box wall of the housing 21. Thus, when the docking terminal 22 is installed into the mounting hole 211, the first guide structure and the first mating structure are mutually positioned and engaged, thereby achieving pre-positioning and guiding functions. This allows the docking terminal 22 to be quickly and accurately positioned in the mounting hole 211, avoiding misalignment and improving installation efficiency and quality. The specific locations of the first guide structure and the first mating structure are not limited in this invention. Specifically, in some embodiments, the first mating structure is located on the inner wall of the mounting hole 211, and the first guide structure is located on the docking terminal 22 at a position corresponding to the inner wall of the mounting hole 211. Furthermore, the specific configuration of the first guide structure and the first mating structure can be varied. For example, the first guide structure and the first mating structure can be a protrusion and a groove, specifically, the first guide structure can be a protrusion and the first mating structure a groove; or the first guide structure can be a groove and the first mating structure a protrusion.

[0076] See Figure 8 and Figure 13In this embodiment, the first guiding structure includes a guide groove 2241, and the first mating structure includes a rib 2242 adapted to the guide groove 2241. Specifically, the guide groove 2241 extends along the extension direction of the mating terminal hole 2201, and correspondingly, the rib 2242 is disposed on the inner wall of the mounting hole 211 and extends along the extension direction of the mating terminal hole 2201. Thus, the extension directions of the guide groove 2241 and the rib 2242 are consistent with the installation direction of the mating terminal 22. When the mating terminal 22 is inserted into the mounting hole 211, the cooperation of the guide groove 2241 and the rib 2242 can play a guiding role. The cross-section of the guide groove 2241 can be V-shaped, U-shaped, semi-circular, square, etc., and the present invention does not limit this. It is understood that the cross-section of the rib 2242 is preferably designed to be consistent with the cross-sectional shape of the guide groove 2241.

[0077] Furthermore, the number of the first guiding structure and the first mating structure is not limited in this invention. Multiple first guiding structures can be provided, or only one can be provided. Correspondingly, the number of first mating structures is consistent with the number of first guiding structures, ensuring a one-to-one correspondence between the two. (See also...) Figure 8 In this embodiment, there are two first guide structures and two first mating structures.

[0078] Furthermore, in some embodiments, a limiting portion 2251 is provided on the inner wall of the mounting hole 211, and a limiting groove 2252 is formed between the limiting portion 2251 and the inner wall of the mounting hole 211. The limiting groove 2252 extends along the extending direction of the docking terminal hole 2201 and penetrates the outer wall surface of the housing 21. A limiting block 2253 is provided on the outer wall of the docking terminal 22 to cooperate with the limiting groove 2252. The limiting block 2253 and the limiting groove 2252 cooperate with each other to limit the displacement of the docking terminal 22 in a direction away from the inner wall of the mounting hole 211. The limiting block 2253 and the limiting groove 2252 are designed so that when the mating terminal 22 is inserted into the mounting hole 211, the limiting block 2253 can be inserted into the limiting groove 2252. At this time, the limiting part 2251 abuts against the limiting block 2253, which restricts the limiting block 2253 from moving away from the inner wall of the mounting hole 211, thereby ensuring that the mating terminal 22 is well fixed in the mounting hole 211 and preventing shaking. For details, please refer to Figure 10 and Figure 13In this embodiment, the limiting part 2251 includes a fixing part and a bending part. The fixing part is fixed on the inner wall of the mounting hole 211, and the bending part is located at the end of the fixing part away from the inner wall of the mounting hole 211. The bending part is arranged parallel to and spaced apart from the inner wall of the mounting hole 211, thereby defining a limiting groove 2252 between the bending part, the fixing part and the inner wall. The limiting groove 2252 extends along the extension direction of the docking terminal hole 2201 and penetrates the outer wall surface of the box 21 to form an entrance. When the docking terminal 22 is inserted into the mounting hole 211, the limiting block 2253 on the outer wall of the docking terminal 22 is inserted into the limiting groove 2252 from the entrance.

[0079] Of course, the design of the present invention is not limited to this. In some embodiments, the limiting part 2251 can also be provided on the outer wall of the docking terminal 22, and correspondingly, the limiting block 2253 is provided on the inner wall of the mounting hole 211. In addition, one or more limiting parts 2251 and limiting blocks 2253 can be provided. When multiple are provided, multiple limiting parts 2251 and multiple limiting blocks 2253 are provided in a one-to-one correspondence.

[0080] Furthermore, the integrated connection terminal 13 is mounted on the housing 10, and there are various specific mounting methods. In one embodiment, the housing 10 is provided with a mounting hole 101, and the integrated connection terminal 13 is inserted into the mounting hole 101. During assembly, the integrated connection terminal 13 is simply inserted into the mounting hole 101. Further, in order to fix the integrated connection terminal 13 and prevent it from falling off, the outer wall of the integrated connection terminal 13 is provided with a second snap-fit ​​part 1331. At the same time, the housing 10 is provided with a second mating part 1332 that cooperates with the second snap-fit ​​part 1331. Thus, when the integrated connection terminal 13 is installed in the mounting hole 211 along the extension direction of the connection terminal hole 1301, the second snap-fit ​​part 1331 and the second mating part 1332 are engaged, thereby preventing the integrated connection terminal 13 from falling out of the mounting hole 101. Specifically, in some embodiments, the second latching portion 1331 is a latching protrusion 1331a, and the edge of the mounting hole 101 forms a second mating portion 1332. When the integrated connection terminal 13 is installed in the mounting hole 101, the latching protrusion 1331a abuts against the edge of the mounting hole 101, thereby preventing the integrated connection terminal 13 from disengaging from the mounting hole 101. In other embodiments, the second latching portion 1331 is configured as a latch hook 1331b, and the second mating portion 1332 is configured as a latch groove 1332b adapted to the latch hook 1331b. See reference. Figure 15 and Figure 18In this embodiment, the hook 1331b is disposed on the outer wall of the integrated connection terminal 13, and one end is spaced apart from the integrated connection terminal 13. The slot 1332b is disposed on the housing 10 and spaced apart from the assembly hole 101. Thus, when the integrated connection terminal 13 is inserted into the assembly hole 101, the hook 1331b is inserted into the slot 1332b and is engaged with the slot 1332b, thereby fixing the integrated connection terminal 13.

[0081] Furthermore, a second guide structure is provided on the outer wall of the integrated connection terminal 13, and a second mating structure adapted to the second guide structure is provided on the housing 10. Thus, when the integrated connection terminal 13 is installed into the mounting hole 101, the second guide structure and the second mating structure are mutually positioned and engaged, thereby achieving pre-positioning and guiding functions. This allows the integrated connection terminal 13 to be quickly and accurately positioned in the mounting hole 101, avoiding misalignment and improving installation efficiency and quality. The specific locations of the second guide structure and the second mating structure are not limited in this invention. Specifically, in some embodiments, the second mating structure is located on the inner wall of the mounting hole 101, and the second guide structure is located on the integrated connection terminal 13 at a position corresponding to the inner wall of the mounting hole 101. Furthermore, there are various options for the specific configuration of the second guide structure and the second mating structure. For example, the second guide structure and the second mating structure can be a protrusion and a groove, specifically, the second guide structure can be a protrusion and the second mating structure can be a groove; or the second guide structure can be a groove and the second mating structure can be a protrusion.

[0082] See Figure 14 and Figure 15 In this embodiment, the second guiding structure includes a guide rib 1333, and the second mating structure includes a guide groove 1334 adapted to the guide rib 1333. Specifically, the guide rib 1333 extends along the extension direction of the connecting terminal hole 1301, and correspondingly, the guide groove 1334 is disposed on the inner wall of the assembly hole 101 and extends along the extension direction of the connecting terminal hole 1301. Thus, the extension directions of the guide groove 1334 and the guide rib 1333 are consistent with the installation direction of the integrated connecting terminal 13. When the integrated connecting terminal 13 is inserted into the assembly hole 101, the mating of the guide groove 1334 and the guide rib 1333 can play a guiding role. Furthermore, the number of the second guiding structure and the second mating structure is not limited in this invention. Multiple second guiding structures can be provided, or only one can be provided. Correspondingly, the number of second mating structures is consistent with the number of second guiding structures, so that the two maintain a one-to-one correspondence. (See reference...) Figure 15 In this embodiment, there are two second guide structures and two second mating structures.

[0083] Because the indoor unit involves numerous wiring structures distributed across various locations, it is necessary to provide multiple integrated connection terminals 13 in different positions to facilitate easier connection between these wiring structures and the integrated connection terminals 13, and to ensure neater wiring within the casing 10. Correspondingly, multiple docking terminals 22 are provided to correspond one-to-one with each of the integrated connection terminals 13. However, when the multiple integrated connection terminals 13 are distributed in different positions, especially on opposite sides of the casing 10, installing the control box 20 in only one direction cannot guarantee that all docking terminals 22 can be docked with each integrated connection terminal 13. Therefore, the casing 10 can be disassembled into multiple components, and the docking of the multiple integrated connection terminals 13 and the multiple docking terminals 22 can be achieved through the sequential assembly of these components and the control box 20. In some embodiments, the housing 10 includes a first component 11 and a second component 12. The first component 11 is provided with a mounting position for the electrical control box, and the second component 12 is detachably mounted on the first component 11. The integrated connection terminal 13 includes a first integrated connection terminal 131 and a second integrated connection terminal 132, and the mating terminal 22 includes a first mating terminal 221 and a second mating terminal 222. Specifically, the first integrated connection terminal 131 is disposed on the first component 11; the second integrated connection terminal 132 is disposed on the second component 12; the first mating terminal 221 is disposed on the electrical control box 20 and corresponds to the first integrated connection terminal 131, and the second mating terminal 222 is disposed on the electrical control box 20 and corresponds to the second integrated connection terminal 132. In this way, multiple wiring structures can be divided into two groups according to their positions. One group is connected to the first integrated connection terminal 131, and the other group is connected to the second integrated connection terminal 132. This makes the wiring more flexible, can adapt to the complex wiring situation inside the wall-mounted indoor unit 100, and also makes the wiring more organized, which is convenient for testing and maintenance, and has a higher aesthetic appearance.

[0084] Specifically, based on the wiring configuration of the wall-mounted indoor unit 100, multiple motor wiring terminals on the motor can be grouped into one group, and other wiring structures, such as the electric auxiliary heating wiring terminal, the pipe temperature sensor wiring terminal, and the grounding structure, can be grouped into another group. For example, in one embodiment, the wall-mounted indoor unit 100 further includes an electric auxiliary heating wiring terminal, a pipe temperature sensor wiring terminal, and a grounding structure, with the first integrated connection terminal 131 electrically connected to the electric auxiliary heating wiring terminal, the pipe temperature sensor wiring terminal, and the grounding structure, respectively. In another embodiment, the wall-mounted indoor unit 100 further includes multiple motor wiring terminals, with the second integrated connection terminal 132 electrically connected to the multiple motor wiring terminals. Of course, it is understood that the grouping method is not limited to the above; the first integrated connection terminal 131 / second integrated connection terminal 132 can also be simultaneously connected to other wiring structures, such as other sensor wiring structures.

[0085] In some embodiments, the control box 20 can be installed and separated from the first component 11 along a first direction; the second component 12 can be installed and separated from the first component 11 along a second direction. In this embodiment, the control box 20 has a first end portion in the first direction and a first side portion in the second direction. A first mating terminal 221 is disposed at the first end portion of the control box 20, and a second mating terminal 222 is disposed at the first side portion of the control box 20. Thus, when the control box 20 is installed to the first component 11 along the first direction, the first mating terminal 221 and the first integrated connection terminal 131 can be mated. Then, when the second component 12 is installed to the first component 11 along the second direction, the second mating terminal 222 and the second integrated connection terminal 132 can be mated.

[0086] In another embodiment, the first direction and the second direction are arranged in the same direction. For example, as... Figure 1 As shown, the electrical control box 20 can be installed and separated from the first component 11 along the first direction; the second component 12 can also be installed and separated from the first component 11 along the first direction. In this embodiment, the electrical control box 20 has two opposite ends located in the first direction, and the first docking terminal 221 and the second docking terminal 222 are correspondingly arranged at the two opposite ends of the electrical control box 20. Thus, by simply installing the electrical control box 20 and the second component 12 sequentially along the first direction, the docking of the first docking terminal 221 and the first integrated connection terminal 131, as well as the docking of the second docking terminal 222 and the second integrated connection terminal 132, can be achieved. This is simple and quick. If an automated system is used to assist in the installation, the automated system required for this assembly method is simpler and easier to control.

[0087] The first component 11 and the second component 12 can be any type of part of the housing 10. For example, the first component 11 can be a faceplate, and the second component 12 can be a panel. See reference. Figure 1 and Figure 4In one embodiment, the first component 11 is the first chassis 110, and the second component 12 is the second chassis 120. That is, in this embodiment, the chassis is divided into two parts, one is the first chassis 110, and the other is the second chassis 120. The electrical control box 20 and the first integrated connection terminal 131 are installed on the first chassis 110, and the second integrated connection terminal 132 is installed on the second chassis 120. Furthermore, the first chassis 110 and the second chassis 120 are formed by disassembling the entire chassis along a third direction, which is perpendicular to the first direction. Specifically, normally, the motor and the electric auxiliary heating component are located on opposite sides of the housing 10. In this embodiment, the first chassis 110 and the second chassis 120 are separated along the third direction. The electric auxiliary heating component can be installed in the first chassis 110, and the motor can be installed in the second chassis 120. In this way, the wiring scheme, which combines the first integrated connection terminal 131 with the electric auxiliary heating wiring part, the pipe temperature sensor wiring part and the grounding structure, and the second integrated connection terminal 132 with the multiple motor wiring parts, helps to organize and integrate the wiring. Moreover, the disassembly and assembly of the first chassis 110 and the second chassis 120 will not affect the grouped wiring structure.

[0088] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
