[0062] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0063] 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.

[0064] The indoor unit of a wall-mounted air conditioner generally includes a chassis and a face frame, the back of the chassis can be attached to the wall (for example, the chassis can be attached to the surface of the wall, that is, the chassis can be attached to the wall), and the chassis can be installed with internal structures of the indoor unit such as a heat exchanger, and the face frame is covered on the chassis to encapsulate the chassis so that the indoor unit forms an integral structure. The face frame and the chassis are generally detachable structures to facilitate operators to repair the internal structure of the indoor unit.

[0065] However, there is a defect that it is not easy to disassemble the face frame and the chassis. 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. 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.

[0066] Furthermore, the present applicant has improved the disassembly method between the above-mentioned face frame and chassis in the early stage. The face frame and chassis are connected together by a sliding buckle. When the face frame needs to be removed 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 achieve 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 current direction is mistakenly believed to be 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.

[0067] In view of this, in order to solve the technical problem that the face frame 100 is inconvenient to be removed from the chassis 200, refer to Figures 1 to 9 An embodiment of the utility model provides a shell assembly, which is used for an air conditioner, and the shell assembly includes a face frame 100, a chassis 200 and a locking member 120. The face frame 100 is a semi-enclosed structure, and at least has a front frame plate, an upper frame plate, a left frame plate and a right frame plate. The upper frame plate can be a grille structure to facilitate air intake into the indoor unit of the air conditioner. The left frame plate and the right frame plate can be solid plates to form an integral support frame of the face frame 100, thereby improving the overall structural strength of the face frame 100. The rear side and the lower side of the face frame 100 are open structures to facilitate connection between the face frame 100 and the chassis 200. The chassis 200 is adapted to the structural shape of the face frame 100, and can be L-shaped, including at least a rear wall plate and a lower wall plate. The side of the rear wall plate facing away from the face frame 100 can be hung on a wall surface such as a wall, so as to realize the overall hanging installation of the shell assembly. An installation cavity is formed between the rear wall plate and the lower wall plate, and internal structures such as air supply components and heat exchange components can be installed in the installation cavity.

[0068] Furthermore, one side of the face frame 100 has an assembly opening 110, the chassis 200 is configured to be assembled in the face frame 100 through the assembly opening 110, the chassis 200 has a locking structure 210, the locking member 120 is connected to the face frame 100, the locking member 120 includes a locking portion 121 and an unlocking portion 122 connected to each other, and the locking portion 121 is in a locked position connected to the locking structure 210. The unlocking portion 122 is configured to be driven to move toward the inside of the face frame 100 to drive the locking portion 121 to move to an unlocking position separated from the locking structure 210, so that the chassis 200 can be separated from the face frame 100 through the assembly opening 110.

[0069] Specifically, in order to solve the above problem, in the present embodiment, when it is necessary to realize the installation between the face frame 100 and the chassis 200, firstly align the assembly port 110 of the face frame 100 with the chassis 200, and then push the face frame 100 inward in the direction close to the chassis 200, so that the chassis 200 is assembled in the face frame 100 through the assembly port 110, and finally utilize the snap-fit ​​cooperation between the locking structure 210 and the locking member 120 to realize the fixed connection between the chassis 200 and the face frame 100. When it is necessary to disassemble the face frame 100 and the chassis 200, it is first necessary to unlock the locking structure 210 and the locking member 120. For example, the unlocking portion 122 of the locking member 120 can be pressed downward so that the unlocking portion 122 can be driven to move toward the inside of the face frame 100. Driven by the unlocking portion 122, the locking portion 121 of the locking member 120 can move in a direction away from the locking structure 210, so that the locking portion 121 can be separated from the locking structure 210, thereby unlocking the locking member 120 and the locking structure 210. At this time, the face frame 100 and the chassis 200 are in an unlocked state, and then the face frame 100 can be removed from the chassis 200 by pulling the face frame 100 outward, so that the operator can repair and replace the internal structure of the indoor unit.

[0070] The housing assembly provided in this embodiment has a simple structure, and is convenient for installation and removal of the housing assembly. By simply snapping the locking portion 121 of the locking member 120 onto the locking structure 210, the locking member 120 and the locking structure 210 can be locked, which is conducive to the installation of the face frame 100 and the chassis 200. By simply pressing the unlocking portion 122 of the locking member 120, the unlocking of the locking member 120 and the locking structure 210 can be achieved, which is conducive to the removal of the face frame 100 and the chassis 200. In the process of installing and removing the housing assembly, it is not necessary to use a large force to operate, which effectively prevents damage to the housing assembly due to excessive force. At the same time, the locking member 120 and the locking structure 210 can be unlocked by using a small pressing force, which is more convenient for operators to remove the face frame 100 and the chassis 200.

[0071] Moreover, compared to the structure in which the unlocking portion 122 is driven to slide and unlock on the surface wall of the face frame 100, the pressing direction of the unlocking method for the face frame 100 and the chassis 200 provided in the present embodiment is unique, and the operator does not need to attempt unlocking operations in multiple directions. The locking member 120 and the locking structure 210 can be easily unlocked simply by pressing downward. Therefore, the unlocking method for the face frame 100 and the chassis 200 provided in the present embodiment is also beneficial for the operator to blindly operate the shell assembly, reduces the difficulty of the operator in installing and disassembling the shell assembly, and improves the operator's efficiency in installing and disassembling the shell assembly.

[0072] Furthermore, in some embodiments, the surface of the unlocking portion 122 may be provided with a friction pattern, and when the operator needs to unlock the locking member 120, the position of the unlocking portion 122 can be immediately sensed by touching the friction pattern, so that the operator can press the unlocking portion 122 to facilitate the unlocking operation between the locking member 120 and the locking structure 210, so as to facilitate the disassembly of the face frame 100 and the chassis 200. By providing the friction pattern on the surface of the unlocking portion 122, the operator's search time for the unlocking portion 122 can be shortened, and the operator can perform blind operation more conveniently.

[0073] Furthermore, in some embodiments, the surface of the unlocking portion 122 may be provided with a friction bump. When the operator needs to unlock the locking member 120, the operator can immediately sense the position of the unlocking portion 122 by touching the friction bump, so that the operator can press the unlocking portion 122 to realize the unlocking operation between the locking member 120 and the locking structure 210, so as to disassemble the face frame 100 and the chassis 200. Compared with the form of friction pattern, the form of friction bump can be more conducive to the operator to sense the position of the unlocking portion 122 by touch, so as to quickly complete the unlocking operation between the face frame 100 and the chassis 200.

[0074] Furthermore, in some embodiments, the locking member 120 can be integrally connected with the face frame 100. By designing the locking member 120 and the face frame 100 as an integrally formed structure, it is beneficial to improve the integrity of the housing assembly, to ensure the connection stability between the locking member 120 and the face frame 100, and to reduce the subsequent steps of installing the locking member 120 on the face frame 100. Alternatively, the locking member 120 can also be connected to the face frame 100 through a torsion spring. By using the torsion spring to detachably connect the locking member 120 and the face frame 100, when the locking member 120 is damaged, it is convenient to partially replace the locking member 120, which is beneficial to reduce the cost of replacing the entire face frame 100.

[0075] In some embodiments, reference Figure 2 and Figure 4 The locking member 120 further includes a connecting portion 123 , the connecting portion 123 is connected to the face frame 100 , and the locking portion 121 and the unlocking portion 122 are respectively connected to two opposite ends of the connecting portion 123 .

[0076] Specifically, in this embodiment, the locking member 120 is connected to the face frame 100 through the connecting portion 123. On the one hand, the connecting portion 123 can provide a connection support for the locking member 120 to ensure that the locking member 120 can be stably connected to the face frame 100. On the other hand, since the housing assembly provided in this embodiment is unlocked between the locking member 120 and the locking structure 210 by pressing the unlocking portion 122, when the operator presses the unlocking portion 122, the locking member 120 will perform a slight rotational movement. At this time, the connecting portion 123 is equivalent to the rotation fulcrum of the locking member 120, so that the locking member 120 can perform a slight rotational movement with the connecting portion 123 as the center of the circle. In addition, the connecting portion 123 can also play a role in rotation limiting the movement of the locking member 120, preventing the operator from excessively pressing the unlocking portion 122 and causing damage to the locking member 120.

[0077] Further, in some embodiments, for example, the locking portion 121 may be in the form of a hook structure, and the locking structure 210 may be in the form of a buckle structure, the hook and the buckle can be snap-fitted, and the locking portion 121 and the unlocking portion 122 may be arranged on the same vertical line. When the operator presses the unlocking portion 122 downward, that is, when the operator drives the unlocking portion 122 to move into the face frame 100, the locking portion 121 will also move downward under the drive of the unlocking portion 122, and will gradually move to the unlocking position, so that the locking portion 121 and the locking structure 210 are in a separated state, and at this time there is a separation gap between the locking portion 121 and the locking structure 210, and the operator can separate the face frame 100 from the chassis 200 by pulling out the face frame 100, so as to realize the disassembly of the face frame 100, and then the operator can repair the internal structure of the chassis 200.

[0078] It should be noted that since the upper connecting portion of the face frame 100 and the chassis 200 is not convenient to operate, it can be connected using the locking structure 210 and the locking member 120 provided in this embodiment, while the lower connecting portion of the face frame 100 and the chassis 200 still needs to be fixedly connected using connecting structures such as screws to ensure the connection stability between the face frame 100 and the chassis 200 and realize an all-round connection between the face frame 100 and the chassis 200.

[0079] In some embodiments, reference Figure 2 and Figure 4The connecting portion 123 is rotatably connected to the face frame 100 , and the unlocking portion 122 is configured to drive the locking portion 121 to move outward from the face frame 100 to an unlocking position during the process of being driven to move into the face frame 100 .

[0080] Specifically, in this embodiment, another design form of the locking member 120 is provided, that is, the locking portion 121 and the unlocking portion 122 can be arranged on the same horizontal line. For example, the locking member 120 can be analogous to a "seesaw" structure. When the operator presses the unlocking portion 122, the connecting portion 123 can act as a rotation fulcrum, and the locking member 120 can move around the connecting portion 123, so that the locking member 120 can make an approximate circular motion with the connecting portion 123 as the center of the circle, so that when the unlocking portion 122 moves downward in the direction close to the face frame 100 (that is, when the unlocking portion 122 is driven to move toward the inside of the face frame 100), the locking portion 121 can move upward in the direction away from the face frame 100 (that is, the locking portion 121 moves toward the outside of the face frame 100), thereby separating the locking portion 121 and the locking structure 210, so that the locking member 120 and the locking structure 210 are in an unlocked state, which facilitates the disassembly of the face frame 100 and the chassis 200, and further facilitates the operator to repair and replace the internal structure of the indoor unit.

[0081] In addition, when installing the face frame 100, after the locking structure 210 and the locking member 120 are matched and connected, a "click" collision sound is emitted to remind the operator that the chassis 200 and the face frame 100 have been positioned.

[0082] In some embodiments, reference Figure 2 and Figure 4 The locking member 120 also includes a connecting portion 123, which is rotatably connected to the face frame 100. A protrusion is provided on both sides of the connecting portion 123 in a direction parallel to the rotation axis of the connecting portion 123. The connecting portion 123 is integrally connected to the face frame 100 through the protrusion, and the protrusion is configured to generate elastic torsional deformation during the rotation of the connecting portion 123 relative to the face frame 100.

[0083] Specifically, in this embodiment, the locking member 120 can be connected to the face frame 100 through the connecting portion 123 as an integral part. For example, the locking member 120, the connecting portion 123 and the face frame 100 can be injection molded. By designing the locking member 120 and the face frame 100 as an integrally molded structure, it is beneficial to improve the integrity of the housing assembly, to ensure the connection stability between the locking member 120 and the face frame 100, and to reduce the subsequent steps of installing the locking member 120 on the face frame 100.

[0084] Alternatively, in some embodiments, the locking member 120 further includes a connecting portion 123, which is rotatably connected to the face frame 100, and protrusions are respectively provided on both sides of the connecting portion 123 along a direction parallel to the rotation axis of the connecting portion 123, and the protrusions are rotatably connected to the face frame 100, and the shell assembly further includes an elastic member, which is respectively connected to the connecting portion 123 and the face frame 100, and the elastic member is configured to generate elastic deformation during the rotation of the connecting portion 123 relative to the face frame 100.

[0085] Specifically, in this embodiment, the connection part 123 can be detachably connected to the face frame 100. For example, the connection part 123 can be detachably connected to the face frame 100 through a torsion spring, that is, the elastic member in this embodiment can be referred to as a torsion spring. When the operator presses the unlocking part 122, the unlocking part 122 will move downward toward the face frame 100. At this time, the connection part 123 acts as a rotation axis, and the torsion springs arranged on both sides of the connection part 123 will generate torque or rotational force. The torsion spring will be elastically deformed, so that the locking member 120 will rotate relatively under the action of the pressing force. Then, as the unlocking part 122 continues to move downward toward the face frame 100, the locking part 121 will continue to tilt upward in the direction away from the face frame 100. Finally, the locking part 121 will move to the unlocking position and separate from the locking structure 210 to generate a separation gap. At this time, the face frame 100 and the chassis 200 are in a separated state, and the operator can pull the face frame 100 outward to complete the disassembly of the face frame 100 and the chassis 200. When the operator no longer presses the unlocking portion 122, since the torsion spring has undergone elastic deformation before, when the external pressing force disappears, the torsion spring has a tendency to return to its original state, so the torsion spring will rotate to its initial state. Under the action of the torsion spring, the locking member 120 can automatically reset, so that the unlocking portion 122 moves upward in the direction away from the face frame 100, and the locking portion 121 moves downward in the direction close to the face frame 100, ultimately ensuring that the unlocking portion 122 and the locking portion 121 return to their original positions.

[0086] The above-mentioned detachable connection method is adopted between the connecting portion 123 and the face frame 100. When the shell assembly is used for a long time and the elastic member is aged and insensitive, in order to prevent the connecting portion 123 and the face frame 100 from loosening and avoid the face frame 100 and the chassis 200 from being unable to be fastened any more, the elastic member can be partially replaced without replacing the entire face frame 100 as a whole, thereby saving the cost of replacing the face frame 100 and realizing the reuse of the face frame 100.

[0087] It should be noted that the connection method of the torsion spring is a common technical means in the art, so how to achieve the connection between the connecting portion 123 and the face frame 100 by the torsion spring will not be described in detail here.

[0088] In some embodiments, reference Figure 2 , Figure 4 , Figure 6 and Fig. 9 The locking structure 210 includes a snap-fitting protrusion 211, and the locking portion 121 includes a snap-fitting groove 1211. The snap-fitting protrusion 211 extends into the snap-fitting groove 1211 to achieve snap-fitting between the locking structure 210 and the locking portion 121. The locking portion 121 is configured to move to the unlocking position so that the snap-fitting protrusion 211 extends out of the snap-fitting groove 1211.

[0089] Specifically, in the present embodiment, a specific structure of a locking structure 210 and a locking portion 121 and a specific matching relationship between the locking structure 210 and the locking portion 121 are provided. When the face frame 100 and the chassis 200 are in an assembled connection state, the snap-fitting protrusion 211 will extend into the snap-fitting groove 1211 to achieve the snap-fitting between the face frame 100 and the chassis 200. In other words, the snap-fitting groove 1211 will be sleeved on the snap-fitting protrusion 211 to achieve the snap-fitting between the face frame 100 and the chassis 200. The snap-fitting protrusion 211 will clamp the snap-fitting groove 1211, limiting the circumferential movement of the snap-fitting groove 1211 relative to the snap-fitting protrusion 211, thereby achieving the positioning connection between the face frame 100 and the chassis 200. When the operator applies a downward pressing force to the unlocking portion 122, the unlocking portion 122 will move downward toward the inside of the face frame 100, and the locking portion 121 will move upward toward the outside of the face frame 100. At this time, the engaging groove 1211 will be disengaged from the engaging protrusion 211, and the engaging protrusion 211 no longer plays a positioning and limiting role on the engaging groove 1211. After the locking portion 121 moves to the unlocking position, the engaging groove 1211 and the engaging protrusion 211 are completely separated, that is, the face frame 100 is in a movable state. At this time, the operator can pull the face frame 100 outward to complete the disassembly of the face frame 100, so that the operator can repair and replace the structure on the chassis 200.

[0090] Furthermore, in other embodiments, based on the same structural principle, the locking structure 210 may also include a snap-fitting groove 1211, and the locking portion 121 then includes a snap-fitting protrusion 211, which may extend into the snap-fitting groove 1211 to achieve snap-fitting between the locking structure 210 and the locking portion 121, and the snap-fitting protrusion 211 may extend out of the snap-fitting groove 1211 to achieve unlocking and separation between the locking structure 210 and the locking portion 121.

[0091] In some embodiments, reference Figure 1 , Figure 3 , Figure 5 and Figure 7 The face frame 100 is configured to be separated from the chassis 200 along a first direction X, and the engaging protrusion 211 is configured to extend into the engaging groove 1211 along a second direction Y, and the second direction Y intersects with the first direction X.

[0092] Specifically, in the present embodiment, the direction in which the face frame 100 is pulled out and the direction in which the face frame 100 is snap-fitted and positioned are intersecting and not in the same direction. Thus, when the shell assembly is in a static placement state, the face frame 100 will be stably fixed in the second direction Y without a tendency to slide in the first direction X, so that the snap-fit ​​protrusion 211 effectively clamps the snap-fit ​​groove 1211, preventing the snap-fit ​​protrusion 211 and the snap-fit ​​groove 1211 from being easily separated under the action of gravity, thereby failing to ensure the stability of the connection between the face frame 100 and the chassis 200.

[0093] Further, preferably, the first direction X can be referred to as a horizontal direction, and the second direction Y can be referred to as a vertical direction, that is, the first direction X and the second direction Y are arranged vertically. The face frame 100 can be installed on the chassis 200 in the horizontal direction, or the face frame 100 can be separated from the chassis 200 in the horizontal direction. When the face frame 100 is installed on the chassis 200 in the horizontal direction, it will be snap-fitted with the chassis 200 in the vertical direction (specifically, the snap-fitting protrusion 211 and the snap-fitting groove 1211 will be snap-fitted in the vertical direction), which is equivalent to the snap-fitting protrusion 211 limiting the movement of the face frame 100 in the horizontal direction, thereby achieving stable positioning of the face frame 100 and preventing the face frame 100 from spontaneously sliding.

[0094] In some embodiments, reference Figures 1 to 9 The chassis 200 includes a main body 220, a clamping protrusion 211 connected to one side of the main body 220 along the second direction Y, and the clamping protrusion 211 is protruded from the main body 220 along the second direction Y. The face frame 100 includes a frame plate 130 located at one side along the second direction Y, the frame plate 130 is provided with a connecting hole 131 opposite to the clamping protrusion 211, and the locking member 120 is disposed in the connecting hole 131 and connected to the frame plate 130.

[0095] Specifically, in this embodiment, taking the direction of normal installation of the housing assembly in actual application as an example, the clamping protrusion 211 is arranged above the chassis 200, and accordingly, through the cooperation of the connecting hole 131 and the clamping protrusion 211, the locking member 120 will eventually be installed above the chassis 200. It should be noted that in the actual installation process of the housing assembly, a certain installation gap needs to be reserved above the housing assembly. With the above structure, when the operator needs to disassemble the face frame 100 and the chassis 200, the operator can easily touch the position of the locking member 120 by extending his hand along the first direction X, so that the operator can press the locking member 120, so that the locking member 120 and the locking structure 210 are in an unlocked state, and finally the disassembly between the face frame 100 and the chassis 200 is realized.

[0096] In some embodiments, reference Figures 1 to 9The locking member 120 is connected to the side of the frame plate 130 near the assembly opening 110. And / or, the locking member 120 is connected to the side of the frame plate 130 along one side of the third direction Z, and the third direction Z intersects the first direction X and the second direction Y respectively.

[0097] Specifically, in order to facilitate the operator to press the locking piece 120 from various directions (illustratively, for example, from the front of the shell assembly, or from the side of the shell assembly), in the present embodiment, the locking piece 120 is arranged on the side edge of the frame plate 130 close to the assembly port 110. In other words, the locking piece 120 is arranged on the side of the frame plate 130 on one side along the third direction Z. More specifically, the locking piece 120 is arranged at a side position close to the shell assembly. In this way, when the operator needs to disassemble the face frame 100 and the chassis 200, the operator can easily touch the position of the locking piece 120 by extending his hand along the third direction Z, thereby facilitating the operator to press the locking piece 120, so that the locking piece 120 and the locking structure 210 are in an unlocked state, thereby finally realizing the disassembly between the face frame 100 and the chassis 200.

[0098] Furthermore, in this embodiment, a spatial rectangular coordinate system is used as an example for demonstration. If it is assumed that the first direction X is the X-axis direction and the second direction Y is the Z-axis direction, then the third direction Z is the Y-axis direction.

[0099] Furthermore, in combination with the above embodiment, the locking member 120 is arranged at the side of the housing assembly, and the operator can easily touch the locking member 120 by hand, whether from the front of the housing assembly or from the side of the housing assembly (the rear of the housing assembly needs to be fixed on the wall), so that the operator can press and unlock the locking member 120. The above-mentioned position arrangement of the locking member 120 is conducive to shortening the time for the operator to find the location of the locking member 120, reducing the difficulty of disassembling the housing assembly, and improving the disassembly efficiency of the housing assembly.

[0100] In some embodiments, reference Figures 1 to 4 ,as well as Figure 8 A side edge of the frame plate 130 close to the assembly opening 110 is provided with an avoidance opening 132, which is located on one side of the connecting hole 131 along the first direction X and is connected to the connecting hole 131. When the face frame 100 is assembled to the chassis 200, the clamping protrusion 211 extends from the avoidance opening 132 into the connecting hole 131 along the first direction X and connects to the locking portion 121.

[0101] Specifically, in order to simplify the installation process between the face frame 100 and the chassis 200 and reduce the difficulty of installation between the face frame 100 and the chassis 200, in the present embodiment, corresponding to the position of the locking structure 210, the frame plate 130 is provided with an avoidance opening 132 at the edge of the assembly opening 110, and the avoidance opening 132 allows the snap-fitting protrusion 211 of the locking structure 210 to pass through, so that the snap-fitting protrusion 211 can smoothly enter the connecting hole 131 and cooperate with the locking portion 121 of the locking member 120 to realize the snap-fitting fixation between the face frame 100 and the chassis 200.

[0102] Furthermore, during the actual installation of the face frame 100, the face frame 100 can be horizontally slidably installed on the chassis 200. During the horizontal sliding of the face frame 100, the engaging protrusion 211 first passes through the avoidance opening 132, then reaches the connection hole 131, and engages with the locking portion 121 of the locking member 120, thereby completing the mating connection between the face frame 100 and the chassis 200. Since the face frame 100 has a large deadweight, the above-mentioned method of slidingly installing the face frame 100 is conducive to reducing the operating burden of the operator when installing the face frame 100, simplifying the operating steps when installing the face frame 100, and realizing the rapid installation of the face frame 100.

[0103] In some embodiments, reference Figures 1 to 4 ,as well as Figure 8 The face frame 100 is connected with a reinforcing portion 133 , which has two opposite ends respectively connected to the side edges of the frame plate 130 close to the assembly opening 110 , and the two ends of the reinforcing portion 133 are correspondingly connected to the two sides of the avoidance opening 132 , and the reinforcing portion 133 is arched in a direction away from the chassis 200 to avoid the snap-on protrusion 211 .

[0104] Specifically, referring to the above embodiment, since an avoidance opening 132 is opened on the side of the frame plate 130 close to the assembly opening 110, a gap is formed at the avoidance opening 132, which will destroy the structural stability of the edge position of the frame plate 130. In this embodiment, in order to reinforce the edge position of the frame plate 130, a reinforcing portion 133 is provided at the position where the avoidance opening 132 is opened on the frame plate 130. By providing the reinforcing portion 133, it is beneficial to improve the structural stability of the frame plate 130 at the edge position, so that the edge position of the frame plate 130 can withstand greater force and is not easily damaged.

[0105] Furthermore, in order to ensure that the snap-fit ​​protrusion 211 can smoothly pass through the avoidance opening 132 and to avoid the setting of the reinforcement portion 133 from hindering the passage of the snap-fit ​​protrusion 211, the reinforcement portion 133 will be arched in the direction away from the chassis 200 to form a passing space at the avoidance opening 132, thereby ensuring that the snap-fit ​​protrusion 211 can smoothly pass through the avoidance opening 132.

[0106] In some embodiments, reference Figure 8 The side of the locking portion 121 facing the assembly opening 110 has a first guide surface 1212 for guiding the engaging protrusion 211 . Along the first direction X, the first guide surface 1212 gradually approaches the chassis 200 .

[0107] Specifically, in order to ensure that the locking portion 121 and the locking structure 210 can be smoothly snap-fitted together, and to avoid the formation of movement obstacles between the locking portion 121 and the snap-fitting protrusion 211, which makes it impossible to achieve the snap-fitting between the locking portion 121 and the locking structure 210, in the present embodiment, a first guide surface 1212 is provided on the side of the locking portion 121 close to the snap-fitting protrusion 211. The first guide surface 1212 may be an inclined surface, and along the first direction X, the first guide surface 1212 is gradually inclined upward toward the direction close to the snap-fitting protrusion 211, so that the thickness of the side of the locking portion 121 close to the snap-fitting protrusion 211 is relatively thick, and the thickness of the side of the locking portion 121 away from the snap-fitting protrusion 211 is relatively thin.

[0108] When the face frame 100 is installed by sliding along the first direction X, the snap-fitting protrusion 211 will first contact the thinner side of the locking portion 121 and then contact the thicker side of the locking portion 121. During this process, the first guide surface 1212 can guide the snap-fitting protrusion 211, reduce the frictional resistance between the locking portion 121 and the snap-fitting protrusion 211, and avoid the formation of contact resistance between the locking portion 121 and the snap-fitting protrusion 211 so as to prevent further movement, so that the snap-fitting protrusion 211 can more easily enter the snap-fitting groove 1211 of the locking portion 121, thereby realizing the snap-fitting cooperation between the locking structure 210 and the locking member 120, and realizing the installation connection between the face frame 100 and the chassis 200.

[0109] In some embodiments, reference Figure 5 , Figure 6 , Figure 7 and Fig. 9 The chassis 200 includes a main body 220, a clamping protrusion 211 is connected to the main body 220, and a second guide surface 2111 is provided at one end of the clamping protrusion 211 away from the main body 220. The locking member 120 includes a connecting portion 123 rotatably connected to the face frame 100, and a rotation axis of the connecting portion 123 is perpendicular to the extension direction of the clamping protrusion 211 and perpendicular to the direction from the connecting portion 123 to the clamping groove 1211. From the connecting portion 123 to the clamping groove 1211, the second guide surface 2111 gradually approaches the main body 220.

[0110] Specifically, in order to ensure that the locking portion 121 and the locking structure 210 can be unlocked smoothly and to avoid the inability to completely disengage the locking groove 1211 and the locking protrusion 211, which leads to the inability to unlock the locking portion 121 and the locking structure 210, in the present embodiment, a second guide surface 2111 is provided on the side of the locking protrusion 211 close to the locking portion 121. The second guide surface 2111 may be an inclined surface, and along the third direction Z, the second guide surface 2111 is gradually inclined upward toward the direction close to the unlocking portion 122, so that the thickness of the side of the locking protrusion 211 close to the unlocking portion 122 is relatively thick, and the thickness of the side of the locking protrusion 211 away from the unlocking portion 122 is relatively thin.

[0111] When the unlocking portion 122 is pressed to unlock the locking portion 121 and the snap-fitting protrusion 211, the unlocking portion 122 will move toward the inside of the face frame 100, and the locking piece 120 will use the connecting portion 123 as the rotation axis to make the locking portion 121 move toward the outside of the face frame 100. When the locking portion 121 moves to the unlocking position, since the thickness of the end of the snap-fitting protrusion 211 away from the unlocking portion 122 is relatively thin, that is, the height of the end of the snap-fitting protrusion 211 away from the unlocking portion 122 is relatively low, a larger separation gap will be generated between the locking portion 121 and the snap-fitting protrusion 211, thereby facilitating the face frame 100 to be pulled away from the chassis 200.

[0112] Furthermore, the end corners of the snap-fit ​​protrusion 211 can be designed to be rounded, which is helpful to improve the guiding effect of the snap-fit ​​protrusion 211, so that when the unlocking portion 122 is pressed to unlock the locking member 120 and the locking structure 210, the locking portion 121 can be more easily separated from the snap-fit ​​protrusion 211.

[0113] In some embodiments, the unlocking portion 122 is arranged to protrude from the outer wall of the face frame 100, so that the unlocking portion 122 has a relatively protruding touch. When the operator needs to unlock the locking member 120, the position of the unlocking portion 122 can be immediately sensed by touching the unlocking portion 122, so that the operator can press the unlocking portion 122 to realize the unlocking operation between the locking member 120 and the locking structure 210, so as to disassemble the face frame 100 and the chassis 200. By setting the unlocking portion 122 protruding, the operator's search time for the unlocking portion 122 can be shortened, and the operator can perform blind operation conveniently.

[0114] Correspondingly, another embodiment of the utility model further provides an air conditioner, which includes the housing assembly in any of the above embodiments. The air conditioner also includes a heat exchange assembly, an air supply assembly and a panel, wherein the heat exchange assembly is arranged in the face frame 100 and connected to the chassis 200, the air supply assembly is arranged in the face frame 100 and connected to the chassis 200, and the panel is movably connected to the side of the face frame 100 away from the assembly opening 110.

[0115] Specifically, in this embodiment, the air conditioner using the above-mentioned shell assembly is conducive to the disassembly of the face frame 100 and the chassis 200, thereby facilitating the maintenance of the internal structures of the air conditioner such as the heat exchange assembly and the air supply assembly.

[0116] Thanks to the improvement of the above-mentioned shell assembly, the air conditioner provided in this embodiment can produce the same technical effect as the above-mentioned shell assembly, which will not be described in detail here.
