Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Art

[0002] In a wall-mounted air conditioner indoor unit, an electric control box is usually arranged at the end of the internal space of the wall-mounted air conditioner indoor unit, such as the left end or the right end. However, such an arrangement will increase the overall length of the wall-mounted air conditioner indoor unit. On the one hand, it will lead to an increase in the materials used for the base, middle frame and panel of the air conditioner, increasing the cost of the air conditioner. On the other hand, it will also make it difficult to place the air conditioner in the indoor space.

[0003] Therefore, some existing wall-mounted air conditioner indoor units arrange the electric control box in front of the wind wheel motor, that is, on the side close to the main indoor space. However, since the heat exchanger body of the indoor heat exchanger is connected to the refrigerant pipe, the rear wall of the electric control box is relatively close to the refrigerant pipe. If the air conditioner falls, there is a risk that the electric control box will hit the refrigerant pipe, resulting in damage to the refrigerant pipe. Especially in the drop test of the air conditioner, when the electric control box hits the refrigerant pipe, the refrigerant pipe will be damaged and it is difficult to pass the drop test. Summary of the Utility Model

[0004] The purpose of the first aspect of the present utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of the existing electric control box hitting the refrigerant pipe.

[0005] The wall-mounted air conditioner indoor unit provided by the first aspect of the present utility model includes a base, an electric control box, and an indoor heat exchanger installed on the base. The indoor heat exchanger includes a heat exchanger body and a refrigerant pipe connected to the end of the heat exchanger body. The electric control box is located in front of the refrigerant pipe, and the electric control box includes a box body and a support component arranged on the box body. The support component is configured to abut against the heat exchanger body.

[0006] The beneficial effects brought by the wall-mounted air conditioner indoor unit of the present utility model are as follows:

[0007] By arranging a support component on the box body of the electric control box and configuring the support component to be able to abut against the heat exchanger body, when the wall-mounted air conditioner indoor unit falls, especially during the drop test, if the electric control box moves backward relative to the heat exchanger body, the abutment between the support component and the heat exchanger body can be used to prevent further movement of the electric control box relative to the heat exchanger body, so as to prevent the electric control box from hitting the refrigerant pipe and causing defects in the refrigerant pipe.

[0008] In an optional technical solution, the side wall of the box body facing the heat exchanger body is the first side wall, and the support component is arranged on the outer side surface of the first side wall.

[0009] The support component is arranged on the side wall of the box body facing the heat exchanger body. Compared with being arranged at other positions, it is beneficial to shorten the distance between the position where the support component contacts the heat exchanger body and the box body, which is beneficial to improving the stiffness of the support component and preventing the support component from breaking when the support component collides with the heat exchanger body, and preventing the box body from directly hitting the refrigerant pipe.

[0010] In an optional technical solution, the support component includes a support plate, and the support plate extends along a first direction from the first side wall, and the support plate is configured to abut against the front surface of the heat exchanger body.

[0011] By arranging the support plate to extend along the first direction, the possible contact area between the support plate and the heat exchanger body can be increased, so as to disperse the acting force to more areas of the heat exchanger body, reduce the concentration of the acting force on the heat exchanger body, and reduce the degree of damage to a single part of the heat exchanger body.

[0012] In an optional technical solution, the support component further includes a support rib plate, and the support rib plate is connected to the outer side surfaces of the support plate and the first side wall.

[0013] By arranging the support rib plate, the connection stiffness and connection strength of the support plate can be increased. Compared with the stress mode of the support plate being a cantilever beam structure, the ability of the support plate to bear impacts can be significantly improved.

[0014] In an optional technical solution, a first plug-in member is provided on the base, and a second plug-in member that is inserted and cooperates with the first plug-in member is provided on the box body; the first plug-in member includes a first plug-in portion and a first connection portion, and the first connection portion connects the base body of the base; the second plug-in member includes a second plug-in portion, the second plug-in portion is connected to the box body, and the second plug-in portion is inserted into the first plug-in portion.

[0015] By arranging the first connection portion to connect the first plug-in portion and the base body, a gap can be generated between the first connection portion and the base body, so as to facilitate the insertion of the second plug-in portion connected to the electric control box into the first plug-in portion, and avoid the inconvenience of the insertion operation and the disconnection operation of the second plug-in portion and the first plug-in portion caused by the second plug-in portion being arranged at too low a position.

[0016] In an optional technical solution, the first plug-in portion is a male plug-in portion, and the second plug-in portion is a female plug-in portion; the width of the first plug-in portion is smaller than the inner wall spacing of the second plug-in portion, and a guiding rib plate is provided between the inner walls of the second plug-in portion. The guiding rib plate matches the first plug-in portion, and the guiding rib plate extends along the first insertion direction in which the first plug-in portion is inserted into the second plug-in portion.

[0017] By setting the width of the first plug-in part to be smaller than the inner wall spacing of the second plug-in part, the width of the second plug-in part as the female plug-in part is increased, which is beneficial for one side wall of the second plug-in part to share the same board with the box body. On the one hand, the material usage is reduced, and on the other hand, it can avoid the difficulty in injection molding caused by the too small spacing between two adjacent boards. By setting the guiding rib plate, when the inner wall spacing of the second plug-in part is greater than that of the first plug-in part, it can ensure that both side walls of the first plug-in part can be effectively limited, thus ensuring the connection accuracy.

[0018] In an alternative technical solution, a first chamfering part is provided at the free end of the first plug-in part, and the first chamfering part is located at the lower edge of the free end of the first plug-in part; along the first insertion direction, the thickness of the first plug-in part gradually decreases.

[0019] By setting the first chamfering part at the lower edge of the free end of the first plug-in part, the first chamfering part can be used to abut against the bottom wall below the entrance of the second plug-in part, so that when the first plug-in part is inserted slightly lower than the preset position of the second plug-in part, in other words, when the second plug-in part is sleeved slightly higher than the preset position of the first plug-in part, it can play a guiding role in the relative movement of the two. Thus, it is convenient for the second plug-in part to be sleeved on the first plug-in part even when the two are not completely aligned.

[0020] In an alternative technical solution, the guiding rib plate is provided with a second chamfering part, and the second chamfering part is located at the entrance end of the guiding rib plate; along the first insertion direction, the interval between the second chamfering part and its opposite surface gradually decreases.

[0021] By setting the second chamfering part at the entrance end of the guiding rib plate, when there is a slight deviation in the front-back position of the first plug-in part relative to the second plug-in part, the first plug-in part can be smoothly inserted into the second plug-in part. Moreover, by setting the second chamfering part that can compensate for the front-back position deviation on the guiding rib plate, the first plug-in part can have sufficient dimensions in the front-back direction, so that the matching length of the first plug-in part and the guiding rib plate in the front-back direction is relatively large, improving the stability of the first plug-in part after being inserted into the second plug-in part.

[0022] In an alternative technical solution, the first plug-in member is further provided with a first anti-retreat part; the first anti-retreat part is configured to be able to be inserted into the second plug-in part; the first anti-retreat part includes a first cantilever, a guiding part and a first anti-retreat surface, the first cantilever connects the guiding part and the first plug-in part, the guiding part is located in the second direction of the first plug-in part, the guiding part has a guiding surface, the guiding surface is located on one side of the guiding part in the second direction, and the thickness of the guiding part provided with the guiding surface gradually decreases along the first insertion direction; there is an interval between the guiding part and the first plug-in part;

[0023] The second connector is also provided with a second stop portion; the second stop portion is a stop hole on the side wall of the second connector, and the first stop surface is configured to abut against the hole wall of the stop hole; the first stop portion is configured so that when the interval between the introduction portion and the first connector is reduced, the first stop surface disengages from the stop hole.

[0024] By utilizing the first cantilever to connect the introduction part and the first plug-in part, since the first cantilever is not an absolutely rigid body, during the process of inserting the introduction part into the second plug-in part, the introduction surface of the introduction part can be utilized to abut against the edge of the entrance end of the second plug-in part to compress the introduction part, and reduce the interval between the introduction part and the first plug-in part, thereby deforming the first cantilever so that the introduction part can be smoothly inserted into the second plug-in part, and the first stop surface can be utilized to abut against the hole wall of the stop hole to achieve the stop locking of the first stop part.

[0025] If the electric control box needs to be removed, the first stop portion can be pressed through the stop hole, thereby reducing the interval between the introduction portion and the first plug-in portion, so that the first stop surface is disengaged from the stop hole, thereby releasing the stop function of the first stop portion and the second stop portion, so that the first stop portion and the first plug-in portion can be pulled out of the second plug-in portion. Therefore, the first cantilever is used to connect the introduction portion and the first plug-in portion, which is not only conducive to more conveniently inserting the first plug-in portion and the first stop portion into the second plug-in portion, but also convenient for releasing the stop lock of the first stop portion and the second stop portion.

[0026] The second aspect of the utility model aims to provide an air conditioner to solve the technical problem of the electric control box hitting the refrigerant pipe.

[0027] The air conditioner provided in the second aspect of the utility model comprises an air conditioner outdoor unit and any one of the above-mentioned wall-mounted air conditioner indoor units, wherein the air conditioner outdoor unit is connected to the wall-mounted air conditioner indoor unit via a refrigerant connecting pipe.

[0028] By arranging the above-mentioned wall-mounted air-conditioning indoor unit in the air conditioner, accordingly, the air conditioner has all the advantages of the above-mentioned wall-mounted air-conditioning indoor unit, which will not be described one by one here.

[0048] Embodiment 1:

[0049] Figure 1 It is a schematic structural diagram of an implementation mode of a wall-mounted air conditioner indoor unit provided in Embodiment 1 of the present utility model; Figure 2 It is a schematic structural diagram of an implementation mode of a wall-mounted air conditioner indoor unit provided in Embodiment 1 of the present utility model observed from another direction; Figure 3 It is a schematic structural diagram of the electric control box in an implementation mode of a wall-mounted air conditioner indoor unit provided in Embodiment 1 of the present utility model; Figure 4 It is a schematic structural diagram of the electric control box in another implementation mode of a wall-mounted air conditioner indoor unit provided in Embodiment 1 of the present utility model. As Figures 1 - 4As shown in the figure, the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model includes a base 300, an electric control box 200, and an indoor heat exchanger 100 installed on the base 300. The indoor heat exchanger 100 includes a heat exchanger body 110 and a refrigerant pipe 120 connected to the end of the heat exchanger body 110. The electric control box 200 is located in front of the refrigerant pipe 120. The electric control box 200 includes a box body 210 and a support assembly 230 provided on the box body 210. The support assembly 230 is configured to abut against the heat exchanger body 110.

[0050] By providing the support assembly 230 on the box body 210 of the electric control box 200 and configuring the support assembly 230 to be able to abut against the heat exchanger body 110, when the wall-mounted air conditioner indoor unit falls, especially during the drop test, if the electric control box 200 moves backward relative to the heat exchanger body 110, the abutment between the support assembly 230 and the heat exchanger body 110 can be utilized to prevent the further movement of the electric control box 200 relative to the heat exchanger body 110, so as to prevent the electric control box 200 from hitting the refrigerant pipe 120 and causing defects in the refrigerant pipe 120.

[0051] In this embodiment, the wall-mounted air conditioner indoor unit includes a base 300, a middle frame (not shown in the figure), and a front panel (not shown in the figure). When the wall-mounted air conditioner indoor unit is installed indoors, it is necessary to first fix the wall-mounted board (not shown in the figure) on the wall, such as nailing it on the wall, and then hang the main body of the wall-mounted air conditioner indoor unit on the wall-mounted board. The base 300 is the part of the wall-mounted air conditioner indoor unit for installing on the wall-mounted board. The middle frame is installed on the base 300, and the indoor heat exchanger 100 is arranged inside the middle frame. The indoor heat exchanger 100 is installed on the base 300. The front panel is installed on the middle frame. The electric control box 200 is located between the refrigerant pipe 120 and the middle frame.

[0052] Among them, in this embodiment, the refrigerant pipe 120 includes a U-shaped pipe 121 and a refrigerant branch pipe 122. The U-shaped pipe 121 is used to connect different regions of the indoor heat exchanger 100 to play the role of reversing the refrigerant flow in the heat exchanger body 110 of the indoor heat exchanger 100. The refrigerant branch pipe 122 is used to connect the refrigerant connection pipe 130 and different regions of the indoor heat exchanger 100. The refrigerant connection pipe 130 is connected to the air conditioner outdoor unit. The refrigerant branch pipe 122 is used to distribute the refrigerant flowing from the air conditioner outdoor unit to different regions of the indoor heat exchanger 100 or to collect the refrigerant in different regions of the indoor heat exchanger 100 to the refrigerant connection pipe 130.

[0053] In this embodiment, the heat exchanger body 110 may include heat exchanger side wall plates (not shown), heat exchanger inner tubes (not shown), and heat dissipation fins (not shown). The heat exchanger inner tube is used to connect the U-shaped tube 121 and the refrigerant branch pipe 122. The heat exchanger side wall plates are arranged at the ends of the heat exchanger inner tubes, and the heat dissipation fins are connected to the heat exchanger inner tubes and arranged along the length direction of the heat exchanger inner tubes to increase the contact area with the flowing air and improve the heat exchange capacity. The heat dissipation fins are also arranged parallel to the heat exchanger side wall plates. If the wall-mounted air conditioner indoor unit drops and the support assembly 230 abuts or even collides with the heat exchanger body 110, it will also come into contact with the heat exchanger side wall plates and the heat dissipation fins, at most causing deformation of the heat exchanger side wall plates and the heat dissipation fins, and will not directly impact the refrigerant pipe 120, nor will it cause cracks or the like on the refrigerant pipe 120, thus not substantially affecting the normal operation of the wall-mounted air conditioner indoor unit, so as to ensure passing the drop test.

[0054] In this embodiment, the box body 210 of the electric control box 200 includes a box cover and a box seat. The support assembly 230 is arranged on the box seat. It should be noted that in this application, the support assembly 230 is configured to abut against the heat exchanger body 110, which means that when there is a drop and a large impact occurs, the support assembly 230 can abut against the heat exchanger body 110, while when the wall-mounted air conditioner indoor unit is in normal transportation, storage, and use and there is no drop, the support assembly 230 can leave a gap with the heat exchanger body 110.

[0055] In addition, the electric control box 200 is also provided with a connecting ear plate 241. The connecting ear plate 241 is connected to the bottom of the front surface of the box body 210. The connecting ear plate 241 is also connected to the box body 210 through a connecting rib plate 242 to improve the connection stiffness of the connecting ear plate 241. Through holes or notches are provided on the connecting ear plate 241 for male threaded connectors such as screws or bolts to pass through. The male threaded connectors are threadedly connected to the threaded hole columns 330 provided on the base 300. By providing the connecting ear plate 241 at the bottom of the box body 210 and connecting it to the threaded hole columns 330 on the base 300 through male threaded connectors, since the electric control box 200 itself has stiffness, when the bottom of the electric control box 200 is fixed, the backward movement amplitude of the electric control box 200 relative to the indoor heat exchanger 100 can also be reduced, thereby reducing the impact of the electric control box 200 on the heat exchanger body 110.

[0056] Figure 5 A three-dimensional cross-sectional view of another implementation manner of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention; as Figures 1 - 5 shown, optionally, the side wall of the box body 210 facing the heat exchanger body 110 is the first side wall, and the support assembly 230 is arranged on the outer side surface of the first side wall.

[0057] The support component 230 is disposed on the side wall of the box body 210 facing the heat exchanger body 110. Compared with being disposed at other positions, it is beneficial to shorten the distance between the position where the support component 230 contacts the heat exchanger body 110 and the box body 210, which is beneficial to improving the rigidity of the support component 230 and preventing the support component 230 from breaking when the support component 230 collides with the heat exchanger body 110, and preventing the box body 210 from directly hitting the refrigerant pipe 120.

[0058] In this embodiment, the electronic control box 200 is disposed at the right end of the wall-mounted air conditioner indoor unit. Therefore, the heat exchanger body 110 is located on the left side of the electronic control box 200, that is, the side wall of the box body 210 facing the heat exchanger body 110 is the left side wall of the box body 210. That is, the first side wall is the left side wall of the box body 210. Therefore, the support component 230 is disposed on the left side surface of the box body 210.

[0059] Of course, in another implementation manner, the support component 230 can also be disposed on the outer side surface of the front wall of the box body 210. For example, the support component 230 can first extend forward from the outer side surface of the front wall of the box body 210, and then extend toward the heat exchanger body 110, so as to contact the heat exchanger body 110 when the wall-mounted air conditioner indoor unit falls, thereby preventing the refrigerant pipe 120 from being hit.

[0060] As Figures 3 - 5 shown, optionally, the support component 230 includes a support plate 231. The support plate 231 extends along a first direction from the first side wall, and the support plate 231 is configured to abut against the front surface of the heat exchanger body 110.

[0061] By setting the support plate 231 to extend along the first direction, the possible contact area between the support plate 231 and the heat exchanger body 110 can be increased, so as to disperse the acting force to more areas of the heat exchanger body 110, so as to reduce the concentration degree of the acting force on the heat exchanger body 110 and reduce the damage degree to a single part of the heat exchanger body 110.

[0062] Wherein, the first direction is parallel to the length direction of the heat exchanger. More specifically, in this embodiment, it can be a direction horizontally to the left. And the support plate 231 is not absolutely a flat plate and can be a bent plate. Each part of the bent plate is arranged parallel to the corresponding part of the heat exchanger body 110. That is, if the surface of the part of the heat exchanger body 110 in contact with the support plate 231 is vertical, then this part of the support plate 231 is also vertical. If the surface of the part of the heat exchanger body 110 in contact with the support plate 231 is inclined, then the surface of this part of the support plate 231 is also inclined, and the inclination angles should be the same.

[0063] More specifically, the support plate 231 can be located at the rear edge of the outer side surface of the first side wall. Since the box body 210 is recessed forward at the rear wall of the end close to the heat exchanger in order to avoid the refrigerant pipe 120, the support plate 231 also has the same shape as the rear wall of the box body 210.

[0064] Figure 5 It is a schematic structural view of the electric control box in another implementation manner of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention, observed from another direction; Figure 6 It is a schematic structural view of another implementation manner of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention; Figure 7 It is a schematic structural view of another implementation manner of the wall-mounted air conditioner indoor unit provided in the first embodiment of the present invention, with the electric control box omitted; as Figures 3 - 7 As shown, optionally, the support assembly 230 further includes a support rib plate 232, and the support rib plate 232 is connected to the support plate 231 and the outer side surface of the first side wall.

[0065] By providing the support rib plate 232, the connection stiffness and connection strength of the support plate 231 can be increased. Compared with the force-bearing mode of the support plate 231 being a cantilever beam structure, the ability of the support plate 231 to bear impacts can be significantly improved.

[0066] Among them, as Figures 2 - 3 shown, in some implementation manners of this embodiment, the support rib plate 232 can be substantially horizontal, or rather, the thickness direction of the support rib plate 232 is substantially parallel to the area where the support rib plate 232 is arranged on the support plate 231. As Figures 4 - 7 shown, in another implementation manner of this embodiment, the support rib plate 232 can be inclined, for example, it can extend obliquely upward from the position where the support rib plate 232 is connected to the support plate 231.

[0068] By providing the first connecting part 312 to connect the first plugging part 311 and the base body of the base 300, a gap can be generated between the first connecting part 312 and the base body of the base 300, so that it is convenient for the second plugging part 221 connected to the electric control box 200 to be plugged with the first plugging part 311, and it is avoided that the second plugging part 221 is arranged at too low a position, resulting in inconvenient plugging operation and unplugging operation between the second plugging part 221 and the first plugging part 311.

[0069] Among them, the first connecting part 312 can be arranged at the lower part of the base 300, and the first connecting part 312 extends upward or obliquely upward from the lower part of the base 300. The first connecting part 312 can adopt the form of intersection connection of multiple plates. On the one hand, the weight and material usage of the first connecting part 312 can be reduced. On the other hand, the material thickness of each part of the base 300 can be made as consistent as possible. When the injection molding material solidifies, the solidification time of the material is similar, which is beneficial to making the surface of the injection molded product smoother and flatter.

The guiding rib plate 222 is matched with the first plugging part 311, and the guiding rib plate 222 extends along the first insertion direction in which the first plugging part 311 is inserted into the second plugging part 221.

[0071] By setting the width of the first plug-in part 311 to be smaller than the inner wall spacing of the second plug-in part 221, the width of the second plug-in part 221 as the female plug-in part is increased, which is beneficial for one side wall of the second plug-in part 221 to share the same plate with the box body 210. On the one hand, the material usage is reduced, and on the other hand, it can avoid the difficulty in injection molding caused by the too small spacing between two adjacent plates. By setting the guiding rib plate 222, when the inner wall spacing of the second plug-in part 221 is greater than that of the first plug-in part 311, the two side walls of the first plug-in part 311 can be effectively limited, thus ensuring the connection accuracy.

[0072] Specifically, in this embodiment, the width of the first plug-in part 311 refers to the dimension of the first plug-in part 311 in the front-rear direction. Similarly, the inner wall spacing of the second plug-in part 221 is also the dimension between the front wall and the rear wall of the second plug-in part 221. In this embodiment, since the connection ear plate 241 is also provided at the bottom of the electric control box 200, the rear wall of the second plug-in part 221 partially serves to connect the main body of the electric control box 200 and the connection ear plate 241. And the first insertion direction, in this embodiment, is the direction from left to right, while in Figure 11 and Figure 12 it is embodied as the direction from right to left in the figure.

[0073] The guiding rib plate 222 protrudes horizontally from the inner sides of the front wall and the rear wall of the second plug-in part 221 and extends horizontally, and can extend from the position of the entrance of the space in the second plug-in part 221 to the inner end of the space of the second plug-in part 221. More specifically, the guiding rib plate 222 can be located at the middle position or the position slightly below the middle in the height direction on the inner sides of the front wall and the rear wall of the second plug-in part 221.

[0074] As Figures 8 - 9 shown, optionally, the free end of the first plug-in part 311 includes a first chamfered part 313, and the first chamfered part 313 is located at the lower edge of the free end of the first plug-in part 311; along the first insertion direction, the thickness of the first plug-in part 311 gradually decreases.

[0075] By setting the first chamfered part 313 at the lower edge of the free end of the first plug-in part 311, the first chamfered part 313 can be used to abut against the bottom wall below the entrance of the second plug-in part 221, so as to play a guiding role in the relative movement of the two when the preset position of the first plug-in part 311 inserted into the second plug-in part 221 is slightly lower, in other words, when the second plug-in part 221 is sleeved on the first plug-in part 311 at a slightly higher preset position. Thus, it is convenient for the second plug-in part 221 to be sleeved on the first plug-in part 311 even when the two are not completely aligned.

[0076] In this embodiment, the thickness of the first insertion part 311 refers to the dimension of the first insertion part 311 in the vertical direction. The dimension between the front and rear surfaces of the first insertion part 311 does not change significantly along the first insertion direction.

[0077] As Figures 11 - 12 shown, the guiding rib 222 is provided with a second chamfered part 223. The second chamfered part 223 is located at the entrance end of the guiding rib 222. Along the first insertion direction, the interval between the second chamfered part 223 and its opposite surface gradually decreases.

[0078] By providing the second chamfered part 223 at the entrance end of the guiding rib 222, when there is a slight deviation in the front-rear position of the first insertion part 311 relative to the second insertion part 221, the first insertion part 311 can be smoothly inserted into the second insertion part 221. Moreover, by providing the second chamfered part 223 that can compensate for the position deviation in the front-rear direction on the guiding rib 222, the first insertion part 311 can have sufficient dimensions in the front-rear direction, so that the mating length of the first insertion part 311 and the guiding rib 222 in the front-rear direction is relatively large, improving the stability after the first insertion part 311 is inserted into the second insertion part 221.

[0079] In this embodiment, guiding ribs 222 are provided on both the front and rear side walls of the inner wall of the second insertion part 221. Thus, the difference between the inner wall spacing of the second insertion part 221 and the width of the first insertion part 311 is compensated. Then, the opposite surface of the second chamfered part 223 of one guiding rib 222 is the surface opposite to the second chamfered part 223 of the other guiding rib 222. That is, the rear surface of the second chamfered part 223 of the guiding rib 222 provided on the inner side surface of the front side wall of the second insertion part 221 is the front surface of the second chamfered part 223 of the guiding rib 222 provided on the inner side surface of the rear wall.

[0080] In another implementation, guiding ribs 222 can be provided only on the inner side surface of the rear wall of the second insertion part 221 or only on the inner side surface of the front wall of the second insertion part 221, which can also play a role in controlling the front-rear position of the first insertion part 311 relative to the second insertion part 221 during the insertion process of the first insertion part 311. Then, the opposite surface of the second chamfered part 223 is the inner wall surface of the second insertion part 221 opposite to this second guiding part. Along the first insertion direction, the interval between the second chamfered part 223 and its opposite surface gradually decreases, indicating that the second chamfered part 223 and the opposite second chamfered part 223 or inner wall surface form an opening that is larger on the outside and smaller on the inside. Here, the outside refers to the entrance end of the second insertion part 221 as the female insertion part.

[0081] As Figures 6 - 12As shown, optionally, the first plug connector 310 is further provided with a first stop portion, which is configured to be inserted into the second plug portion 221; the first stop portion includes a first cantilever 321, an introduction portion 322 and a first stop surface 323, the first cantilever 321 connects the introduction portion 322 and the first plug portion 311, the introduction portion 322 is located in the second direction of the first plug portion 311, the introduction portion 322 has an introduction surface 324, the introduction surface 324 is located on one side of the second direction of the introduction portion 322, and the thickness of the introduction portion 322 provided with the introduction surface 324 gradually decreases along the first insertion direction; a gap is left between the introduction portion 322 and the first plug portion 311;

[0082] The second stop portion is a stop hole 224 on the side wall of the second plug-in portion 221, and the first stop surface 323 is configured to abut the hole wall of the stop hole 224; the first stop portion is configured so that when the interval between the introduction portion 322 and the first plug-in portion 311 is reduced, the first stop surface 323 disengages from the stop hole 224.

[0083] By utilizing the first cantilever 321 to connect the introduction portion 322 and the first plug-in portion 311, since the first cantilever 321 is not an absolutely rigid body, during the process of inserting the introduction portion 322 into the second plug-in portion 221, the introduction surface 324 of the introduction portion 322 can be utilized to abut against the edge of the entrance end of the second plug-in portion 221 to compress the introduction portion 322, and reduce the interval between the introduction portion 322 and the first plug-in portion 311, thereby deforming the first cantilever 321 so that the introduction portion 322 can be smoothly inserted into the second plug-in portion 221, and the first stop surface 323 can be utilized to abut against the hole wall of the stop hole 224, thereby realizing the stop locking of the first stop portion.

[0084] If the electric control box 200 needs to be removed, the first stopper can be pressed through the stopper hole 224, thereby reducing the interval between the introduction part 322 and the first plug-in part 311, so that the first stopper surface 323 is separated from the stopper hole 224, so as to release the stopper function of the first stopper and the second stopper, so that the first stopper and the first plug-in part 311 can be pulled out of the second plug-in part 221. Therefore, the first cantilever 321 is used to connect the introduction part 322 and the first plug-in part 311, which is not only conducive to more conveniently inserting the first plug-in part 311 and the first stopper into the second plug-in part 221, but also conveniently releases the stopper lock of the first stopper and the second stopper.

[0085] In this embodiment, the introduction portion 322 is located above the first plug portion 311 , and the introduction surface 324 is located on the upper surface of the introduction portion 322 , so the second direction is an upward direction. Correspondingly, the stop hole 224 is provided on the upper side wall of the second plug portion 221 .

[0086] When viewed from the front of the air conditioner, the introduction surface 324 of the introduction portion 322 is higher on the left end and lower on the right end. The first chamfered portion 313 is lower on the left end and higher on the right end. Therefore, the first chamfered portion 313 is arranged at the lower edge of the free end of the first plug-in portion 311, and cooperates with the introduction portion 322 to reduce the overall height of the first plug-in portion 311 and the first stop portion at the free end, making it easier for the first stop portion and the first plug-in portion 311 to be inserted into the inlet end of the second plug-in portion 221.

[0087] Of course, in order to improve the connection strength between the first plug connector 310 and the second plug connector 220, the first cantilever 321 can be made to remain deformed after the first stopper portion and the second stopper portion are locked, but the deformation at this time is smaller than the deformation before the introduction portion 322 moves to the stopper hole 224. At this time, the upper surface of the first cantilever 321 is subjected to the pressure of the lower surface of the top wall of the second plug connector 221, and the lower surface of the first plug connector 311 is also subjected to the pressure of the lower surface of the bottom wall of the second plug connector 221. Therefore, the first plug connector 311 and the introduction portion 322 are positioned with the second plug connector 221 in the vertical direction.

[0088] Since the top and bottom sides of the trapezoidal or rectangular vertical cross-section formed by the first plug-in portion 311 and the introduction portion 322 respectively correspond to the top and bottom sides of the second plug-in portion 221, and the guide ribs 222 limit the front and rear surfaces of the first plug-in portion 311, the ability to prevent the first plug-in portion 311, the introduction portion 322 and the second plug-in portion 221 from rotating relative to each other can be improved, and further, when the wall-mounted air-conditioning indoor unit falls, the degree of the upper part of the electric control box 200 tilting backwards can be reduced, thereby reducing the impact between the support assembly 230 and the heat exchanger body 110.

[0089] In another implementation, the thickness direction of the introduction portion 322 may also be the front-to-back direction, and the introduction portion 322 may be located in front of the first plug-in portion 311, then the second direction is the forward direction. Correspondingly, the introduction surface 324 is the front surface of the introduction portion 322. When the introduction portion 322 is inserted into the second plug-in portion 221, the introduction portion 322 is squeezed by the entrance end of the second plug-in portion 221, and it will move backward to facilitate the insertion of the introduction portion 322. The guide rib 222 is arranged on the inner side of the rear wall of the second plug-in portion 221 to support the first plug-in portion 311. Correspondingly, the stop hole 224 is arranged on the front side of the second plug-in portion 221 for the introduction portion 322 and the first stop surface 323 to be inserted and stopped. When the electric control box 200 needs to be removed, the introduction portion 322 needs to be pressed backwards to reduce the distance between the introduction portion 322 and the first plug-in portion 311 so that the first stop surface 323 and the hole wall of the stop hole 224 are free from the stop.
