[0001] The utility model relates to the technical field of air processing equipment, in particular to a shell component, an indoor unit and an air conditioner. Background Art

[0002] The housing assembly of the indoor unit of the air conditioner includes a face frame and a chassis. The back of the face frame has an assembly opening, and the chassis is assembled into the face frame through the assembly opening. The chassis includes a backrest and a base, the backrest covers the assembly opening of the face frame, and the base is located at the bottom of the face frame. The chassis is used to connect the heat exchanger and air supply assembly of the indoor unit of the air conditioner.

[0003] In the related art, the face frame and the chassis are connected by buckles. When the operator needs to remove the face frame from the chassis, the face frame needs to be pried apart at the buckle position to deform the face frame, and then the face frame is removed from the chassis using the gap between the face frame and the chassis. With this operation method, if the force is too small, the face frame cannot be removed from the chassis. If the force is too large, the face frame may be damaged and cannot be installed and used again. Therefore, the solution in the related art is not convenient for removing the face frame.

[0070] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0071] In the related art, the face frame and the chassis are connected by buckles. When the operator needs to remove the face frame from the chassis, the face frame needs to be opened at the buckle position to deform the face frame, and then the face frame is removed from the chassis using the gap between the face frame and the chassis. If the force used is too small, the face frame cannot be removed from the chassis. If the force used is too large, the face frame may be damaged and cannot be installed and used again.

[0072] The present applicant has improved the disassembly method between the face frame and the chassis in the early stage. The face frame and the chassis are connected together by a sliding buckle. When the face frame needs to be disassembled from the chassis, the face frame can be unlocked from the chassis by sliding the slider along the surface wall of the face frame to realize the removal of the face frame from the chassis. However, since the indoor unit is usually hung at a high place, the sliding buckle will form a blind area of ​​vision, so the operator may need to operate blindly during the process of separating the face frame and the chassis. After the operator touches the slider with his hand, he cannot see the structure near the slider and cannot judge the sliding direction of the slider, so he needs to try to slide in different directions to unlock the face frame and the chassis. If the locking force between the slider and the face frame and the chassis is large at this time, even if the operator tries the right direction, it is possible that the driving force is too small when trying to slide the slider (the operator cannot judge whether the current sliding direction is correct, and is worried about damaging the slider by excessive force, so the force may be too conservative), and the face frame and the chassis cannot be unlocked, and then the operator mistakenly believes that the current direction is not the unlocking direction of the slider. In summary, the structure of using a slider to unlock the face frame and the chassis is also not convenient for disassembling the face frame.

[0073] In view of this, see Figure 1-Figure 15 This embodiment provides a housing assembly 10, which is used for an indoor unit of an air conditioner. Figure 1-Figure 4 ,as well as Figure 14-15 The housing assembly 10 includes a face frame 100 , a bottom plate 200 and a locking member 300 . The locking member 300 is used to maintain a detachable connection between the face frame 100 and the bottom plate 200 .

[0074] The face frame 100 is a semi-enclosed structure, see Figure 1-Figure 4 In some embodiments, the face frame 100 may include a front frame plate, an upper frame plate, a left frame plate, a right frame plate, and a lower frame plate (with Figure 1 The first direction X shown in the figure is the front-to-back direction, the second direction Y is the left-to-right direction, and the third direction Z is the up-down direction for illustration). The upper frame plate and the front frame plate can be a grille structure to facilitate air intake and / or air outlet to the indoor unit of the air conditioner. The left frame plate, the right frame plate and the lower frame plate can be solid plates to form an integral support frame of the face frame 100 to improve the overall structural strength of the face frame 100. The rear side of the face frame 100 can be provided with an assembly port 120 to facilitate assembly of the face frame 100 and the chassis 200. The front side of the face frame 100 can be movably connected to the front panel, specifically, the front panel can be rotatably connected to the front panel, so that when the indoor unit is in use, an operator can perform maintenance or cleaning on the components in the face frame 100.

[0075] The chassis 200 is disposed in the face frame 100 and is adapted to the structural shape of the face frame 100. Specifically, the chassis 200 may include a backrest 210 and a base 220. The backrest 210 is disposed at the assembly opening 120 on the rear side of the face frame 100 and covers the assembly opening 120 of the face frame 100. The base 220 is disposed on the lower side of the face frame 100. The rear end of the base 220 is connected to the lower end of the backrest 210 and together constitutes the chassis 200. The indoor unit of the air conditioner may further include an air supply component and a heat exchange component. Both the air supply component and the heat exchange component are disposed in the face frame 100 and are connected to the chassis 200. See Figure 3-Figure 4 In some embodiments, the chassis 200 includes a locking structure 230 , and the locking member 300 cooperates with the locking structure 230 to lock the face frame 100 and the chassis 200 , thereby achieving a detachable connection between the face frame 100 and the chassis 200 .

[0076] See also Figure 1-Figure 4 ,as well as Figure 14-15 , the locking member 300 is rotatably connected to the face frame 100. The locking member 300 can be rotatably connected to any position of the face frame 100 that can cooperate with the chassis 200, that is, the locking member 300 can be rotatably connected to any one of the aforementioned upper frame plate, lower frame plate, front frame plate, left frame plate or right frame plate. The rotation axis of the locking member 300 relative to the face frame 100 can be arbitrarily arranged according to actual needs. In some embodiments, the rotation axis of the locking member 300 relative to the face frame 100 can be perpendicular to the thickness direction of the frame plate 110 connected to the locking member 300; in other embodiments, the rotation axis of the locking member 300 relative to the face frame 100 can be parallel to the thickness direction of the frame plate 110 connected to the locking member 300. Specifically, when the locking member 300 is connected to the upper frame plate of the face frame 100, the rotation axis of the locking member 300 relative to the upper frame plate can be parallel to the thickness direction of the frame plate 110 connected to the locking member 300. Figure 1 Any one of the first direction X, the second direction Y or the third direction Z. For ease of description, the following takes the example that the locking member 300 is connected to the upper frame plate of the face frame 100 and the rotation axis of the locking member 300 relative to the upper frame plate is parallel to the third direction Z.

[0077] See also Figure 9-13The locking member 300 includes a locking portion 310 and an unlocking portion 320 connected to each other. The unlocking portion 320 is configured to rotate relative to the face frame 100 after being driven, so as to drive the locking portion 310 to rotate relative to the face frame 100 to a locked position or an unlocked position. In other words, the user can drive the unlocking portion 320 to rotate the locking member 300 relative to the face frame 100. During the process of the locking member 300 rotating relative to the face frame 100, the locking portion 310 of the locking member 300 can move relative to the face frame 100 to a locked position and an unlocked position. Specifically, when the locking portion 310 is in the locked position, it has a first matching state with the locking structure 230 to lock the chassis 200 and the face frame 100; when the locking portion 310 is in the unlocked position, it has a second matching state with the locking structure 230, so that the chassis 200 can be separated from the face frame 100 by the assembly port 120. When the locking portion 310 and the locking structure 230 are in a first mating state, the locking portion 310 is connected to the locking structure 230; when the locking portion 310 and the locking structure 230 are in a second mating state, the locking portion 310 can be separated from the locking structure 230, or, when the locking portion 310 and the locking structure 230 are in the second mating state, the locking portion 310 can also be connected to the locking structure 230 (for example, the locking portion 310 abuts against the side wall of the locking structure 230), but the locking portion 310 can be separated from the locking structure 230 along a direction, and the face frame 100 is also separated from the chassis 200 along the first direction X, and the direction in which the locking portion 310 is separated from the locking structure 230 is the same as the direction in which the face frame 100 is separated from the chassis 200. In this solution, when the indoor unit needs maintenance, after the locking portion 310 is in the unlocked position, the face frame 100 is driven to move along the first direction X relative to the chassis 200, so that the locking portion 310 can be separated from the locking structure 230 and the face frame 100 can be separated from the chassis 200 connected to the wall.

[0078] The locking member 300 can be detachably connected to the face frame 100 or can be non-detachably connected to the face frame 100. When the locking member 300 is detachably connected to the face frame 100, it is convenient to replace the locking member 300 after the locking member 300 is damaged, and it is also convenient to clean the dust near the locking member 300. When the locking member 300 is non-detachably connected to the face frame 100, the probability of the locking member 300 being lost after the face frame 100 is disassembled can be reduced.

[0079] In the housing assembly 10 of this embodiment, the face frame 100 and the chassis 200 are detachably connected by the locking member 300. The unlocking portion 320 of the locking member 300 is driven to rotate relative to the face frame 100, thereby driving the locking portion 310 to move to a locked position or an unlocked position. When the locking portion 310 rotates relative to the face frame 100 to the locked position, the face frame 100 and the chassis 200 are locked. When the locking member 300 rotates relative to the face frame 100 to the unlocked position, the face frame 100 can be separated from the chassis 200. The face frame 100 and the chassis 200 can be locked and unlocked by driving the unlocking portion 320 of the locking member 300 to rotate relative to the face frame 100. Compared with the structure of prying open the buckle part of the face frame 100 and deforming the face frame 100 to separate it from the chassis 200, on the one hand, the operation is more convenient and the face frame 100 can be separated from the chassis 200 more easily. On the other hand, since there is no need to deform the buckle part of the face frame 100, the probability of damaging the face frame 100 during the removal process is reduced.

[0080] Furthermore, in this embodiment, when the operator knows that the housing assembly 10 can unlock the face frame 100 by driving the unlocking portion 320 to rotate, in the process of blindly operating the unlocking portion 320, after touching the unlocking portion 320, only two opposite rotation directions need to be tried to correctly drive the unlocking portion 320 and unlock the chassis 200, which is more convenient for blind operation to unlock compared to the structural design of using a slider to slide relative to the face frame 100 to unlock the chassis 200. Because when the operator knows that the housing assembly 10 can unlock the chassis 200 by driving the slider to slide relative to the face frame 100, when blindly operating the unlocking portion 320, it is necessary to try to unlock multiple times in an uncertain direction, and the unlocking process is relatively complicated.

[0081] In some embodiments, the face frame 100 and the chassis 200 can be detachably connected only by the locking member 300, that is, no other locking components except the locking member 300 are provided between the face frame 100 and the chassis 200. In other embodiments, the face frame 100 and the chassis 200 can be connected to each other not only by the locking member 300, but also by other structures or components. Exemplarily, in some embodiments, the face frame 100 and the chassis 200 are also threadedly connected by screws. Specifically, the screws can be connected to the front frame plate position of the face frame 100 and the chassis 200 and fix the face frame 100 and the base 220 of the chassis 200. When the panel connected to the face frame 100 is rotated to the closed position, the screws are shielded so that the appearance of the indoor unit is more concise. When the panel connected to the face frame 100 is rotated to the open position, the screws are exposed, so that the operator can operate the tool to remove the screws. In this solution, the combination of the locking member 300 and the screws can make the connection between the face frame 100 and the chassis 200 more stable. In a further embodiment, screws can be connected to the bottom of the face frame 100 and the locking piece 300 is arranged on the top of the face frame 100, so that both the bottom position of the face frame 100 where it is convenient to operate the tool and the top position of the face frame 100 where it is inconvenient to operate the tool (the top of the indoor unit is generally close to the ceiling, which is not convenient for operating the tool) can be well provided with connecting parts connected to the chassis 200, thereby further improving the connection stability between the face frame 100 and the chassis 200.

[0082] See also Figure 1-Figure 3 ,as well as Figure 9-11 In some embodiments, one of the frame plates 110 (specifically, the upper frame plate) of the face frame 100 is provided with a connecting through hole 111. The locking member 300 further includes a connecting portion 330, which is provided through the connecting through hole 111 and can rotate relative to the frame plate 110 around the hole axis of the connecting through hole 111, and the locking portion 310 and the unlocking portion 320 are respectively connected to two opposite ends of the connecting portion 330, specifically, the locking portion 310 is connected to one end of the connecting portion 330 close to the chassis 200, and the locking portion 310 can extend into the interior of the face frame 100 so as to be connected to the chassis 200; the unlocking portion 320 is connected to one end of the connecting portion 330 away from the chassis 200, and the unlocking portion 320 can extend out of the face frame 100 so as to protrude from the face frame 100. In this solution, the locking member 300 can rotate relative to the upper frame plate along an axis parallel to the third direction Z by cooperating with the connecting through hole 111, so that the rotation connection structure between the locking member 300 and the upper frame plate is simpler, and it is more convenient to assemble the locking member 300. In a further embodiment, the portion of the unlocking portion 320 protruding from the frame plate 110 is provided with a strip-shaped protruding structure, which can facilitate the unlocking portion 320 to obtain torque, thereby facilitating the operator to drive the unlocking portion 320 to rotate relative to the frame plate 110.

[0083] The locking member 300 is disposed through the connecting through hole 111, so the arrangement position of the locking member 300 is determined according to the arrangement position of the connecting through hole 111. Figure 5-Figure 9 In some embodiments, the face frame 100 forms an assembly opening 120 on one side along the first direction X, and the connecting through hole 111 is located on the side of the frame plate 110 close to the assembly opening 120. In this case, the locking member 300 is disposed on the side of the face frame 100 close to the assembly opening 120. Since the assembly opening 120 is formed by the rear sides of the upper frame plate, the lower frame plate, the left frame plate, and the right frame plate, the locking member 300 can be disposed on the side of one of the upper frame plate, the lower frame plate, the left frame plate, or the right frame plate of the face frame 100 close to the assembly opening 120. Preferably, the connecting through hole 111 can be disposed on the side of the upper frame plate close to the assembly opening 120. In this solution, since the position of the upper frame plate is not convenient for operating tools, compared with the structure of connecting the upper frame plate and the chassis 200 with screws, the method of locking the upper frame plate and the chassis 200 with the locking member 300 can be more convenient for operators to operate.

[0084] When the locking member 300 is connected to the upper frame plate, the operator needs to extend his hand upward from the front side of the indoor unit into the gap between the upper frame plate and the indoor ceiling to operate the locking member 300. In order to further facilitate the operation of the operator, see Figure 5-Figure 9 In some embodiments, the face frame 100 forms an assembly opening 120 on one side along the first direction X, and the connecting through hole 111 is located on one side of the frame plate 110 along the second direction Y, and the second direction Y intersects the first direction X. In this solution, when the locking member 300 is connected to the upper frame plate, it can be connected to the left and right sides of the upper frame plate. In this solution, when the operator drives the locking member 300, the operator can also extend his hands upward from the left and right sides of the indoor unit into the gap between the upper frame plate and the indoor ceiling to operate the locking member 300, and the operator's operating position is more flexible.

[0085] The locking member 300 rotates relative to the face frame 100 so as to be switchable between a locked position and an unlocked position, and when separating the face frame 100 and the chassis 200, the locking member 300 needs to make the locking portion 310 in the unlocked position, and when assembling the face frame 100 and the chassis 200, the locking portion 310 also needs to be in the unlocked position. When assembling the face frame 100 and the chassis 200, if the locking portion 310 is not in the unlocked position, the locking portion 310 may interfere with the locking structure 230, thereby making it impossible for the face frame 100 to be assembled to the corresponding position of the chassis 200. Therefore, in order to smoothly assemble the face frame 100 and the chassis 200, the operator needs to adjust the locking portion 310 to the unlocked position relative to the face frame 100 before assembling the face frame 100 and the chassis 200. To simplify the above operation, refer to Figure 11-13In some embodiments, the frame plate 110 includes a first limiting portion 116, and the locking member 300 includes a second limiting portion 340. The second limiting portion 340 is configured to connect to the first limiting portion 116 when the locking portion 310 is in the unlocked position, so as to limit the connection portion 330 from rotating relative to the frame plate 110 when the driving force applied to the unlocking portion 320 is less than or equal to a preset value, and the second limiting portion 340 is separated from the first limiting portion 116 when the driving force applied to the unlocking portion 320 is greater than the preset value. That is, before the face frame 100 is assembled with the base 220, the first limiting portion 116 and the second limiting portion 340 can be connected to each other, at which time the locking portion 310 is in the unlocked position and the relative position between the locking portion 310 and the face frame 100 is basically fixed, and the locking portion 310 will not be separated from the unlocked position due to shaking generated during the assembly process, and the operator does not need to pay attention to the position of the locking portion 310 when assembling the face frame 100, thereby reducing the difficulty of assembling the face frame 100. When the face frame 100 is assembled to the corresponding position of the chassis 200, the operator drives the locking part 310 to rotate by driving the unlocking part 320. When the driving force of the operator is greater than the preset value, for example, when the driving force of the operator is greater than or equal to 0.01N*M, the first limiting part 116 and the second limiting part 340 can be separated. At this time, the operator can drive the locking part 310 to move to the locking position, thereby locking the face frame 100 and the chassis 200.

[0086] In order to achieve the purpose of separating the first limiting portion 116 and the second limiting portion 340 when the driving force is greater than the preset value and not separating when the driving force is less than the preset value, see Figure 11-13In some embodiments, the first limiting portion 116 may include a slot 1161, and the second limiting portion 340 includes a convex portion, which is clamped in the slot 1161 and can be separated from the slot 1161 along the circumferential direction of the rotation axis of the locking member 300. Specifically, the first limiting portion 116 is connected to the inner wall of the frame plate 110 facing the chassis 200, and the first limiting portion 116 is provided with a slot 1161 on the side away from the inner wall, and the second limiting portion 340 is located on the side of the frame plate 110 facing the chassis 200 and connected to the outer peripheral wall of the connecting portion 330. When the locking portion 310 is in the unlocking position, the second limiting portion 340 is clamped in the slot 1161, and when the torque along the circumferential direction of the hole axis received by the unlocking portion 320 is greater than a preset value, the second limiting portion 340 is separated from the slot 1161. In this solution, the structures of the first limiting portion 116 and the second limiting portion 340 are simple and easy to process. Further, the first limiting portion 116 can be integrally formed when the frame plate 110 is formed, and the second limiting portion 340 can be integrally formed when the locking member 300 is integrally formed, thereby reducing the processing costs of the first limiting portion 116 and the second limiting portion 340. In other embodiments, the first limiting portion 116 can also be arranged at other positions of the frame plate 110, for example, the first limiting portion 116 can also be arranged at the wall of the frame plate 110 away from the chassis 200; the second limiting portion 340 can also be arranged at the unlocking portion 320 or the locking portion 310. In other embodiments, the first limiting portion 116 and the second limiting portion 340 can also be magnetic elements, and when the locking portion 310 is in the unlocking position, the first limiting portion 116 and the second limiting portion 340 are attracted; when the driving force received by the unlocking portion 320 is greater than the suction force between the first limiting portion 116 and the second limiting portion 340, the first limiting portion 116 and the second limiting portion 340 are separated.

[0087] See also Figure 9-11 ,as well as Figure 14-15In some embodiments, the connection portion 330 includes a connection body 331, a first abutting portion 332, and a second abutting portion 333. The connection body 331 is disposed in the connection through hole 111 and can rotate relative to the frame plate 110 in the connection hole. The first abutting portion 332 is connected to an end of the connection body 331 away from the chassis 200, and the first abutting portion 332 abuts or is spaced from the outer wall of the frame plate 110 away from the chassis 200 to limit the locking member 300 from extending into the face frame 100 along the third direction Z. The second abutting portion 333 is connected to an end of the connection body 331 facing the chassis 200, and the second abutting portion 333 abuts or is spaced from the inner wall of the frame plate 110 facing the chassis 200 to limit the locking member 300 from extending out of the face frame 100 along the third direction Z. The first abutting portion 332 and the second abutting portion 333 jointly restrict the connecting body 331 in the connecting through hole 111, and on the one hand, the locking member 300 is connected to the frame plate 110, and on the other hand, the locking member 300 can rotate relative to the frame plate 110. In this embodiment, after the locking member 300 is connected to the frame plate 110, the connection relationship between the locking member 300 and the frame plate 110 is more stable, and the locking member 300 is not easily separated from the frame plate 110, thereby reducing the steps of additionally assembling the locking member 300 and the frame plate 110 when the operator disassembles the face frame 100, and the operation is more convenient.

[0088] In some embodiments, when the locking member 300 is connected to the face frame 100 in a non-detachable manner, the first abutting portion 332 and the second abutting portion 333 can both be configured to be unable to pass through the connecting through hole 111 of the frame plate 110, so that the locking member 300 cannot be removed from the face frame 100 in a normal use state. In other embodiments, when the locking member 300 can be detachably connected to the frame plate 110, at least one of the first abutting portion 332 and the second abutting portion 333 can be configured to be able to pass through the connecting through hole 111 of the frame plate 110. See Figure 5-Figure 11In a specific solution, the frame plate 110 may be provided with an escape opening 112, the escape opening 112 communicates with the connecting through hole 111, and the locking portion 310 is configured such that when the locking portion 310 is rotated relative to the frame plate 110 to the disassembly position, the locking member 300 passes through the escape opening 112 and is detached from the face frame 100 toward the outside of the face frame 100. When the locking member 300 is rotated relative to the frame plate 110, it can be rotated to a position where the second abutting portion 333 faces the escape opening 112. At this time, the locking portion 310 is in a disassembly position outside the locking position and the unlocking position. When the operator pulls the locking member 300 toward the outside of the face frame 100, the second abutting portion 333 passes through the frame plate 110 from the escape opening 112, thereby detaching the locking member 300 from the frame plate 110. In this embodiment, when the locking portion 310 is in the disassembly position, when viewed along the third direction Z, the size of the second abutment portion 333 can be smaller than the avoidance opening 112, thereby facilitating the locking member 300 to be detached from the face frame 100; or the size of the second abutment portion 333 can be slightly larger than the avoidance opening 112, so that when the operator applies a large driving force to the locking member 300 along the third direction Z, the second abutment portion 333 can pass through the avoidance opening 112 by being squeezed and deformed. This solution can reduce the probability of the locking member 300 accidentally detaching from the face frame 100 while allowing the locking member 300 to be detached from the frame plate 110.

[0089] In the above-mentioned embodiment, the locking member 300 is configured to be able to be separated from the frame plate 110 toward the outside of the frame plate 110. In other embodiments, the locking member 300 may also be configured to be separated from the frame plate 110 toward the inside of the frame plate 110. Specifically, the frame plate 110 may be provided with an escape opening 112, the escape opening 112 is connected to the connecting through hole 111, and the locking portion 310 is configured to rotate relative to the frame plate 110 to the disassembly position, and the first abutting portion 332 rotates to face the escape opening 112, so that the first abutting portion 332 can pass through the escape opening 112, so that the locking member 300 can be separated from the frame plate 110 toward the inside of the frame plate 110.

[0090] See also Figure 5-Figure 13In some embodiments, the locking portion 310 rotates from the unlocked position to the locked position along the first circumferential direction, and rotates from the unlocked position to the disassembly position along the second circumferential direction, and the first circumferential direction is opposite to the second circumferential direction. In other words, the unlocked position is located between the disassembly position and the locked position. When the locking portion 310 is in the unlocked position, the direction in which the locking portion 310 rotates to the locked position is opposite to the direction in which it rotates to the disassembly position. This solution allows the locking member 300 to rotate from the unlocked position to the locked position without passing through the disassembly position, so that it is not easy to accidentally separate from the face frame 100 at the disassembly position during this process. In a further embodiment, the locking member 300 is configured to be unable to rotate around 360 degrees relative to the face frame 100, and at this time, along the first circumferential direction, the locking portion 310 cannot rotate from the unlocked position to the disassembly position, and along the second circumferential direction, the locking portion 310 cannot rotate from the disassembly position to the unlocked position. This solution can further prevent the locking member 300 from accidentally separating from the face frame 100 at the disassembly position during use.

[0091] When the locking member 300 is in the unlocked position, in order to facilitate the locking member 300 to be driven to the locked position, a clearance fit is required between the locking member 300 and the frame plate 110, thereby reducing the driving force for driving the locking member 300 to rotate and facilitating user operation. When the locking member 300 is in the locked position, in order to prevent the locking member 300 from automatically escaping from the locked position due to factors such as vibration generated in the environment, the locking member 300 needs to be positioned more firmly in the locked position. In view of this, see Figure 11-13 In some embodiments, a boss 115 is convexly provided on the inner wall of the frame plate 110 facing the chassis 200. When the locking portion 310 is in the locked position, the boss 115 is located between the first abutting portion 332 and the second abutting portion 333, and the second abutting portion 333 abuts against the boss 115. When the locking portion 310 is in the unlocked position, the boss 115 is separated from the second abutting portion 333. Specifically, when the locking portion 310 is in the unlocked position, since the boss 115 is separated from the second abutting portion 333, the wall surface of the second abutting portion 333 close to the frame plate 110 does not abut against the boss 115. The gap between the second abutting portion 333 and the first abutting portion 332 is larger than the thickness of the frame plate 110. The locking member 300 and the frame plate 110 are in a clearance fit relationship, so that the locking member 300 can be driven more conveniently. When the locking portion 310 is driven from the unlocking position to the locking position, the second abutting portion 333 abuts against the boss 115, so that the gap between the second abutting portion 333 and the frame plate 110 is supplemented by the boss 115, and the second abutting portion 333 and the frame plate 110 are in a tight fit state, so that the friction resistance between the locking member 300 and the frame plate 110 is increased, and the locking member 300 is more firmly positioned in the locked position.

[0092] In the above embodiment, the boss 115 is provided on the side wall of the frame plate 110 facing the chassis 200, and the second abutting portion 333 abuts against the boss 115, thereby enhancing the positioning effect of the locking member 300 in the locked position. In other embodiments, the boss 115 can also be provided on the side wall of the frame plate 110 away from the chassis 200, and when the locking portion 310 is in the locked position, the boss 115 is located between the first abutting portion 332 and the second abutting portion 333, and the first abutting portion 332 abuts against the boss 115, and when the locking portion 310 is in the unlocked position, the boss 115 is separated from the first abutting portion 332. That is, the first abutting portion 332 abuts against the boss 115, thereby enhancing the positioning effect of the locking portion 310 in the locked position.

[0093] In order to prevent foreign matter from entering the face frame 100 through the connecting through hole 111, see Figure 5-Figure 9 In some embodiments, an annular flange 113 is convexly provided on the outer wall of the frame plate 110 away from the chassis 200, and the annular flange 113 is arranged around the outer periphery of the first abutting portion 332, and the annular flange 113 can be arranged at intervals from the first abutting portion 332. The annular flange 113 can prevent foreign matter from entering the connecting through hole 111 through the gap between the first abutting portion 332 and the face frame 100 and finally entering the inside of the face frame 100. On the one hand, it can prevent foreign matter from blocking the gap between the locking member 300 and the face frame 100, thereby hindering the rotation of the locking member 300, and on the other hand, it can also prevent foreign matter from entering the face frame 100 and affecting the operation of the components inside the face frame 100. Further, when the annular flange 113 is provided on the outer side of the unlocking portion 320, along the third direction Z, the unlocking portion 320 can be located on the inner side of the annular flange 113, and the unlocking portion 320 can also extend out of the annular flange 113 in a direction away from the connecting through hole 111. In this embodiment, in order to facilitate the operation of the unlocking portion 320 , the unlocking portion 320 extends out of the annular flange 113 in a direction away from the connecting through hole 111 .

[0094] See also Figure 5-Figure 9 In some embodiments, the outer wall of the frame plate 110 facing away from the chassis 200 is provided with abutting protrusions 114, and the first abutting portion 332 abuts against the end of the abutting protrusions 114 facing away from the chassis 200, so that the first abutting portion 332 is spaced from the outer wall of the frame plate 110 facing away from the chassis 200. Compared with the solution in which the first abutting portion 332 directly abuts against the outer side wall of the chassis 200, since the contact area between the first abutting portion 332 and the abutting protrusions 114 in this solution is smaller, the friction resistance when the locking member 300 rotates is smaller, and it is easier to drive the locking member 300 to rotate compared with the face frame 100. Similarly, in some embodiments, the inner wall of the frame plate 110 facing the chassis 200 can also be provided with abutting protrusions 114, and the second abutting portion 333 abuts against the abutting protrusions 114 so that the second abutting protrusions 114 are spaced from the inner wall of the frame plate 110, thereby further reducing the friction resistance when the locking member 300 rotates.

[0095] The specific form of the locking structure 230 can be arbitrarily set according to actual needs, see Figure 3-Figure 4 ,as well as Figure 9-11 In some embodiments, the face frame 100 is configured to be separated from the chassis 200 along the first direction X, and the locking structure 230 includes a limiting hole 231 provided on the chassis 200 and extending along the first direction X, and the opening 232 of the limiting hole 231 faces the inside of the face frame 100. The locking structure 230 also includes a baffle 233, which is provided in the limiting hole 231, and the baffle 233 has a limiting wall surface 2331 on a side away from the opening 232. The locking portion 310 extends in a direction perpendicular to the rotation axis of the connecting portion 330. When the locking portion 310 is in the unlocking position, it is located on a side of the connecting portion 330 facing the limiting hole 231 and penetrates the limiting hole 231 along the first direction X. When the locking portion 310 is in the locking position, it is located on a side of the connecting portion 330 along the second direction Y and abuts against the limiting wall surface 2331, and the second direction Y intersects with the first direction X. In this solution, when the locking portion 310 is in the unlocking position, the locking portion 310 can extend into the limiting hole 231 at the opening 232 of the limiting hole 231 along the first direction X. When the locking portion 310 is in the locking position, the locking portion 310 can rotate to abut the limiting wall 2331. At this time, the baffle 233 can prevent the locking portion 310 from moving along the first direction X, so that the face frame 100 and the chassis 200 cannot be separated along the first direction X, thereby achieving locking between the face frame 100 and the chassis 200.

[0096] The position of the limiting hole 231 is determined according to the arrangement position of the locking member 300, see Figure 3-Figure 4 ,as well as Figure 9-11 In some embodiments, the locking member 300 is connected to the side of the frame plate 110 of the face frame 100 near the assembly opening 120, and the chassis 200 includes a backrest portion 210, which is located in the assembly opening 120 and at least partially covers the assembly opening 120, and the limiting hole 231 is provided on the backrest portion 210. In this solution, the backrest portion 210 is closer to the rear side of the indoor unit, and the rear side of the face frame 100 is locked by the locking member 300, so that the connection with the chassis 200 is more stable.

[0097] See also Figure 3-Figure 4 ,as well as Figure 9-11In some embodiments, the limiting hole 231 penetrates the chassis 200 along the first direction X, which can increase the movement space of the locking portion 310 to prevent the locking portion 310 from interfering with the hole wall of the limiting hole 231. In some embodiments, the baffle 233 is disposed at the opening 232 and covers part of the opening 232. Compared with the structure in which the baffle 233 is located at the middle position of the limiting hole 231 along the first direction X, the baffle 233 is disposed at the opening 232 of the limiting hole 231, which can make it easier for the locking portion 310 to abut against the limiting wall 2331 of the baffle 233, making locking more convenient. In some embodiments, when the face frame 100 and the chassis 200 are in the assembled position with each other, the locking portion 310 abuts against the hole wall of the limiting hole 231 along the third direction Z when in the locked position and the unlocked position, and the third direction Z intersects the first direction X and the second direction Y respectively. In this solution, the friction between the locking portion 310 and the hole wall of the limiting hole 231 can be increased, thereby further preventing the locking portion 310 from making relative movement with the chassis 200 when subjected to vibration.

The air supply assembly is used to drive the gas circulation, and the circulating gas exchanges heat with the heat exchange assembly after passing through the heat exchange assembly, and the air supply assembly guides the gas after heat exchange out of the face frame 100 and into the room.
