Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular to a snap-fit ​​structure of a grille and a shell and an air conditioner. Background Art

[0002] The grille of a mobile air conditioner usually needs to be fixed on the shell of the air conditioner housing. A filter is installed on the inside of the grille, and the filter will be covered with dust after a period of use. Considering that users need to clean the filter regularly, the grille is usually connected to the housing in a detachable manner such as snap-on or plug-in. However, the buckle structure in the prior art is simple in design and does not provide effective protection for the buckle. During the production, transportation, or loading and unloading of the air conditioner, the buckle is easily hit by other devices, and there is a risk of breakage or failure. Summary of the invention

[0003] The problem to be solved by the present invention is that the buckle structure between the grille and the shell of the existing mobile air conditioner is simply designed, the buckle is not effectively protected, the buckle is easily impacted by other devices, and there is a risk of breakage and failure.

[0004] In order to solve the above problems, the present invention provides a buckle structure between a grille and a shell, including a bridge structure arranged on the grille, the bridge structure including a bridge portion and a first buckle, the bridge portion is provided with a first through hole, and at least a portion of the first buckle is located in the first through hole. By providing the bridge portion, not only can the overall structural strength of the buckle structure be improved; during the loading and unloading process, the bridge portion can also share part of the force to avoid stress concentration and damage to the first buckle, thereby effectively protecting the first buckle and avoiding the buckle structure from being squeezed and collided by other devices during production, transportation, or loading and unloading, and the risk of breaking or fragmentation.

[0005] Optionally, the first buckle includes a first buckle body and a first protrusion disposed at one end of the first buckle body, and at least a portion of the first protrusion is located in the first through hole. It is ensured that at least a portion of the connection between the first buckle and the second buckle is located in the first through hole, thereby improving the protection of the bridge portion to the first buckle.

[0006] Optionally, a width L2 of the first through hole is greater than a maximum length L3 of the first protrusion, so as to facilitate the snap-fitting of the second buckle with the first buckle.

[0007] Optionally, a second through hole is further provided on the bridge portion near one end of the grille, so as to improve the structural stability of the bridge structure and avoid dents, wrinkles, folds and the like on the surface of the bridge portion.

[0008] Optionally, the housing further comprises a second buckle, which is adapted to be engaged with the first buckle; the second buckle comprises a second protrusion, and in the engaged state, at least a portion of the second protrusion is located in the first through hole. The bridge portion can protect not only the first buckle but also the second buckle, thereby increasing the protection range of the bridge portion.

[0009] Optionally, the first protrusion includes a first inclined surface, and the second protrusion includes a second inclined surface, and during the installation and / or removal of the grille and the shell, the bottom end of the first inclined surface is in line contact with the bottom end of the second inclined surface. This arrangement can reduce the friction caused by surface contact and reduce the difficulty of assembly and disassembly of the bridge structure and the second buckle.

[0010] Optionally, when the bridge structure is located at the edge of the upper side of the grille and the second buckle is located at a position matching the bridge structure, the first inclined surface and the vertical surface form a first angle α, the second inclined surface and the vertical surface form a second angle β, and α>β. This prevents the first inclined surface from fitting with the second inclined surface during assembly and disassembly of the grille and the shell, which results in unsmooth assembly and disassembly and requires the application of greater force.

[0011] Optionally, the relationship between the first angle α and the second angle β is: 30°≥α-β≥15°. Within this range, the assembly effect of the grille and the shell is better.

[0012] Optionally, the first angle α and the second angle β are both in the range of 30° to 60°, which reduces the force required for loading and unloading, and also reduces the contact area between the first inclined surface and the second inclined surface, thereby reducing the difficulty of loading and unloading.

[0013] Optionally, a clamping hole is provided on the inner side of the grille, and the clamping hole is adapted to be clamped with a clamping block provided on the filter to fix the filter on the grille. This prevents the filter from blocking part of the air inlet, thereby increasing the air inlet area and reducing the exposure of the filter, thereby improving the overall aesthetics of the product.

[0014] Another object of the present invention is to provide an air conditioner to solve the problem that the buckle structure between the grille and the shell of the existing air conditioner is simply designed, the buckle is not effectively protected, the buckle is easily impacted by other devices, and there is a risk of breakage and failure.

[0015] To solve the above problems, the technical solution of the present invention is achieved as follows:

[0016] An air conditioner includes the above-mentioned snap-fit ​​structure between the grille and the housing. The advantages of the air conditioner and the above-mentioned snap-fit ​​structure between the grille and the housing are the same as those of the prior art, which will not be described in detail here.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] In addition, a brief explanation is given for the orientations involved in this specific implementation: the directions or positional relationships indicated by "front", "back", "up", "down", "left" and "right" etc. mentioned below for each structural member refer to the orientations or positional relationships shown in the accompanying drawings; positional relationships such as "top" and "bottom" are only for the convenience of description and simplified description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] In the embodiment of the present invention, please refer to Figure 1 The coordinates shown are based on the panel where the air inlet is located when the air conditioner is in normal working state as the back, and the other side opposite to it as the front (that is, the panel where the air outlet of the air conditioner is located as the front), and the front, back, left, right, top and bottom three-dimensional spatial directions are defined on this basis. In the embodiments of the present invention, the "inside" is the side close to the internal structure of the air conditioner, and the "outside" is the side close to the indoor environment.

[0035] The existing buckle structure is simple in design. During the assembly process, the two clips are usually snapped together. The snap parts themselves are not effectively protected. During the production, transportation, or loading and unloading process, the snap parts will be squeezed and collided by other devices to a large extent, and there is a risk of breakage and fragmentation. At the same time, during long-term use, the snap parts are snapped multiple times and there is a risk of failure under the action of stress.

[0036] To solve the above-mentioned problems, an embodiment of the present invention provides a snap-fit ​​structure between a grille and a shell. By optimizing the design of the snap-fit ​​structure, a protective structure for the snap-fit ​​parts is added, the overall structural strength of the snap-fit ​​structure is improved, and the risk of damage to the air conditioner during production, transportation, or loading and unloading is reduced.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] Combination Figure 1-2 As shown, a snap-fit ​​structure between a grille and a shell includes a bridging structure arranged on the grille 2, the bridging structure 20 includes a bridging portion 22 and a first snap 21, the bridging portion 22 is provided with a first through hole 221, and at least a portion of the first snap 21 is located in the first through hole 221.

[0039] Specifically, one end of the bridge portion 22 and the first buckle 21 are both fixedly connected to the grille 2, and a first through hole 221 is provided at one end of the bridge portion 22 away from the grille 2, and at least a portion of the free end of the first buckle 21 is located in the first through hole 221. A gap is left between the top surface of the first buckle 21 and the first through hole 221, so that it is convenient for the components that are adapted to the first buckle 21 to pass through the gap and snap into between the bridge portion 22 and the first buckle 21. For the convenience of description, the embodiment of the present invention uses the first through hole 221 as a boundary, and the bridge portion 22 located above the first through hole 221 is called a bridge section, and the other parts of the bridge portion 22 are called base sections. Since at least a portion of the first buckle 21 is located in the first through hole 221, it can be regarded as that the bridge section is erected on the first buckle 21, that is, the bridge section is located at the top of the first buckle 21. In this way, when other devices collide with the bridge structure 20 during production, transportation, or loading and unloading, the bridge portion 22 can resist the impact, thereby protecting the first buckle 21 and preventing the first buckle 21 from being damaged or even broken. At the same time, since the second buckle 11 on the shell 1 is connected to the first buckle 21 through the first through hole 221, that is, when the grille 2 and the shell 1 are assembled, the bridge portion 22 is located between the first buckle 21 and the second buckle 11; therefore, the bridge portion 22 can also improve the overall structural strength of the buckle structure; during the loading and unloading process, the bridge portion 22 can share part of the force to prevent the first buckle 21 from being damaged due to stress concentration.

[0040] Among them, combined Figure 2 , Figure 4 , Figure 5 As shown, the first buckle 21 includes a first buckle body 211 and a first protrusion 212 arranged at one end of the first buckle body 211, and at least a part of the first protrusion 212 is located in the first through hole 221. The first protrusion 212 protrudes in the direction close to the first through hole 221, and the first buckle body 211 is a vertical arm structure, and the two ends of the vertical arm structure are respectively fixedly connected to the grille 2 and the first protrusion 212, and an "L"-shaped clamping platform is formed between the first protrusion 212 and the first buckle body 211, and the "L"-shaped clamping platform is used to cooperate with the matching second buckle 11 arranged on the shell 1 to fix the grille 2 on the shell 1. This arrangement can ensure that the clamping point between the first buckle 21 and the second buckle 11 is located in the first through hole, thereby improving the protection of the bridge portion 22 to the first buckle 21.

[0041] In addition, combined Figure 7 As shown, the width L2 of the first through hole 221 is greater than the maximum length L3 of the first protrusion 212. Here, the width L2 of the first through hole 221 is the distance of the first through hole 221 in the left-right direction, and the maximum length L3 of the first protrusion 212 is the longest distance of the first protrusion 212 in the left-right direction. Since the second buckle 11 needs to be inserted into the "L"-shaped clamping platform for clamping, this configuration facilitates the clamping cooperation between the second buckle 11 and the first buckle 21.

[0042] In order to improve the installation stability of the bridge structure 20, the first buckle 21 and the bridge part 22 are both trapezoidal structures with a narrow top and a wide bottom, and the top thickness of the bridge part 22 is less than the bottom thickness. However, when designing the mold, if the material thickness is uneven, miniature is likely to occur on the plastic product. In order to reduce the occurrence of miniature and avoid dents, wrinkles, folds and the like on the surface of the bridge part 22, a second through hole 222 is further provided at one end of the bridge part 22 away from the first through hole 221; that is, the second through hole 222 is provided on the base section. By providing the second through hole 222, not only can miniature and surface marks be prevented, actual production requirements can be met, and the appearance can be improved, but also the stress concentration phenomenon of the bridge part 22 can be reduced, and the structural stability of the bridge part 22 can be further improved.

[0043] Combination Figure 8-11 As shown, the snap-fit ​​structure between the grille and the shell also includes a second snap-fit ​​11 arranged on the shell 1, and the second snap-fit ​​11 is suitable for snapping with the first snap-fit ​​21; the second snap-fit ​​11 includes a second protrusion 111, and in the snap-fit ​​state, at least a part of the second protrusion 111 is located in the first through hole 221.

[0044] Combination Figure 5-6 As shown, corresponding to the first buckle 21, when the grille 2 is assembled with the housing 1, the second protrusion 111 protrudes in the direction close to the first through hole 221, and the second buckle body 113 is also a vertical arm structure, and the two ends of the vertical arm structure are respectively fixedly connected to the grille 2 and the second protrusion 111, and an "L"-shaped clamping platform is formed between the second protrusion 111 and the second buckle body 113, and the bending direction of the "L"-shaped clamping platform is opposite to that of the "L"-shaped clamping platform of the first buckle 21. The second protrusion 111 is clamped into the first buckle 21 and blocks the first protrusion 212 from moving backward, thereby limiting the first buckle 21, so as to fix the grille 2 on the housing 1. When at least a part of the protruding end of the second protrusion 111 is located in the first through hole 221, it can be further ensured that the clamping point between the first buckle 21 and the second buckle 11 is located in the first through hole 221, and the bridge section is located at the top of the clamping point. With this arrangement, the bridge portion 22 can not only protect the first buckle 21 , but also protect the second buckle 11 , thereby increasing the protection range of the bridge portion 22 .

[0045] The bridge structure 20 may be located at the edges of multiple sides of the grille 2. For ease of description, the following takes the edge state of the bridge structure 20 located at the upper side of the grille 2 as an example to describe the assembly of the bridge structure 20 and the second buckle 11:

[0046] Combination Figure 6 As shown, the first protrusion 212 includes a first inclined surface 213, and the second protrusion 111 includes a second inclined surface 112. During the installation and / or removal process of the grille 2 and the housing 1, the bottom end of the first inclined surface 213 is in line contact with the bottom end of the second inclined surface 112. Here, the bottom end of the first inclined surface 213 is Figure 6 The bottom end of the first inclined surface 213 is Figure 6 The lowermost end of the second inclined surface 112 in the middle. It can be understood that when the bridge structure 20 is located at the other side of the grille 2, the bottom end of the first inclined surface 213 and the bottom end of the second inclined surface 112 are both close to the grille 2, and each position is not described one by one here. When the assembly and disassembly process of the first buckle 21 and the second buckle 11 is line contact, the friction caused by the surface contact can be reduced, and the assembly and disassembly difficulty of the bridge structure 20 and the second buckle 11 is reduced.

[0047] Specific, combined Figure 6 As shown, when the bridge structure 20 is located at the edge of the upper side of the grille 2 and the second buckle 11 is located at a position matching the bridge structure 20, the first inclined surface 213 forms a first angle α with the vertical surface, and the second inclined surface 112 forms a first angle β with the vertical surface, and α>β. Figure 6 The plane in the up-down direction is defined as a vertical plane. When the first angle α is greater than the second angle β, the plane where the first inclined surface 213 is located intersects with the plane where the second inclined surface 112 is located; this also avoids the first inclined surface 213 and the second inclined surface 112 being attached to each other during the assembly and disassembly of the grille 2 and the shell 1, which makes the assembly and disassembly not smooth and requires a large force to be applied.

[0048] Of course, it is understandable that when the bridge structure 20 is located at the edge of the left side or right side of the grille 2, and the second buckle 11 is located at a position matching the bridge structure 20, the first inclined surface 213 forms a first angle α on the horizontal plane, and the second inclined surface 112 forms a second angle β on the horizontal plane. α and β are only used to define the angle relationship between the two surfaces where the first protrusion 212 and the second protrusion 111 contact, and have nothing to do with the positional relationship between the first buckle 21 and the second buckle 11 on the grille 2.

[0049] Preferably, the inventors have found in long-term operational practice that when the first angle α and the second angle β satisfy the relationship: 30°≥α-β≥15°, the assembly effect of the grille 2 and the shell 1 is better. If α-β<15°, the contact area between the first bevel 213 and the second bevel 112 is too large, which makes assembly difficult; and if α-β>60°, the first bevel 213 and the second bevel 112 cannot form effective contact, and cannot play a snap-in effect, which does not meet actual needs.

[0050] In addition, after summarizing the experimental experience, the inventors concluded that the optimal value range of the first angle α and the second angle β is 30° to 60°. It is understandable that the force on one surface will be decomposed along the moment to generate a decomposed force, and if the force on one side is particularly small (the force when close to 90°), the force on the corresponding side will be particularly large, which is not conducive to disassembly and assembly. During the assembly and disassembly process of the grille 2 and the shell 1, only when the value range of the first angle α and the second angle β is within 30° to 60°, a certain decomposed force is generated in the up and down directions, thereby reducing the force required for assembly and disassembly, and also reducing the contact area between the first inclined surface 213 and the second inclined surface 112, reducing the difficulty of assembly and disassembly. If the angles of α and β are both greater than 60°, the first inclined surface 213 and the second inclined surface 112 cannot form a good match, and the second protrusion 111 cannot well limit the first protrusion 212, so that the clamping structure is in a failed state.

[0051] Combination Figure 6 As shown, it can be understood that, considering that the precision of the production mold may not be so high, in the actual production process, an assembly gap is preset between the first bevel 213 and the second bevel 112 to leave a margin for production and improve the product qualification rate. In the buckle structure of the grille and the shell provided by the embodiment of the present invention, the first bevel 213 of the first buckle 21 and the second bevel 112 of the second buckle 11 produce line contact during the assembly and disassembly process, and there is an assembly gap between the first bevel 213 and the second bevel 112 after the assembly is completed, and the matching gap between the first bevel 213 and the second bevel 112 ranges from 0 to 0.3 mm.

[0052] The housing 1 described in the present invention is the rear housing of the air conditioner. The housing 1 is provided with an air inlet 13 for air intake, and an air inlet bracket 14 is provided at the air inlet 13. The grille 2 is mounted on the air inlet bracket 14; the filter is mounted on the inner side of the grille 2 and is located between the air inlet bracket 14 and the grille 2. The grille 2 of the embodiment of the present invention is an "L"-shaped structure, and accordingly, the filter and the air inlet bracket 14 are both "L"-shaped structures adapted to the grille 2. The part of the grille 2 corresponding to the long side of the "L"-shaped structure is located at the rear side of the housing 1, and is called the rear grille 2; the part of the grille 2 corresponding to the short side of the "L"-shaped structure is located on the right side of the housing 1, and is called the right grille 2.

[0053] Combination Figure 1 , Figure 3 As shown, in order to improve the installation stability of the grille 2 and the housing 1, a plurality of bridge structures 20 are provided at the edges of the left side and the upper side of the rear grille 2. The bridge portion 22 of the bridge structure 20 can be formed by folding forward and extending from the upper side of the rear grille 2, or the bridge portion 22 is formed by folding forward and extending from the left side of the rear grille 2. Preferably, two bridge structures 20 are provided at the edges of the left side and the upper side of the rear grille 2.

[0054] Correspondingly, the housing 1 is provided with second buckles 11 having the same number as the bridge structures 20 , and the plurality of buckles can be respectively engaged and adapted with the plurality of bridge structures 20 .

[0055] Combination Figure 3 , Figure 10-11 As shown, the grille 2 is also provided with a latch 23, and the housing 1 is also provided with a socket 12, and the latch 23 is plugged and adapted with the socket 12, that is, the grille 2 and the housing 1 are detachably connected by the snap connection between the first snap 21 and the second snap 11, and the plug connection between the latch 23 and the socket 12. Since the snap connection snap is prone to breakage and failure during long-term loading and unloading, the embodiment of the present invention reduces the risk of failure of the snap connection structure by replacing part of the snap connection structure with a plug-in structure without reducing the installation stability of the grille 2 and the housing 1.

[0056] The latch 23 is a protrusion extending forward or downward from the side of the grille 2. The latch 23 can be a rectangular plate, and the insertion hole 12 is a corresponding rectangular through hole. Of course, the latch 23 can also be a plate in other forms, as long as it can be inserted into the matching latch 23, which is not specifically limited in the embodiment of the present invention.

[0057] The number of the latches 23 can be multiple, and the multiple latches 23 are distributed at the edges of the side of the grille 2. Correspondingly, the housing 1 is provided with the same number of sockets 12 as the latches 23, and the multiple sockets 12 are distributed at corresponding positions of the housing 1. The multiple latches 23 can be plugged and adapted to the multiple sockets 12 respectively. Preferably, in the embodiment of the present invention, multiple latches 23 are provided at the edges of the front side of the right grille 2 and the lower side of the rear grille 2. Specifically, three latches 23 are provided at the edge of the front side of the right grille 2, and two latches 23 are provided at the edge of the lower side of the rear grille 2. It can be known from the above embodiment that multiple bridge structures 20 are provided at the left side and the upper side of the rear grille 2, so that the grille 2 can be fixed to the housing 1 under the joint action of the latch 23 and the socket 12, and the bridge structure 20 and the second buckle 11.

[0058] In addition, the connection between the grille 2 and the housing 1 can be made more secure by optimizing the distribution position of the latches 23. Specifically, the spacing between two adjacent latches 23 located on the side of the same grille 2 can be limited to L1, and 80mm≤L1≤150mm. Considering that the grille 2 is a hollow plate as a whole, and the area is large, the structural strength is not high, and it is easy to bend and deform during long-term use. If the number of latches 23 is small and the distance between two adjacent latches 23 is too large, the grille 2 cannot be tightly fixed on the housing 1; and if the number of latches 23 is too large and the spacing between two adjacent latches 23 is too small, although the connection is very stable, it wastes materials and is not conducive to the matching installation of the latch 23 and the socket 12, which increases the difficulty of assembly. Therefore, only when the spacing between two adjacent latches 23 is within the range of 80 to 150 mm, while ensuring the installation stability of the grille 2 and the housing 1, the difficulty of assembly is not increased.

[0059] In addition, the existing filter screen is injection molded, and the existing filter screen has an airtight edge structure at the periphery, which makes it impossible to completely place it at the inner edge of the grille 2, and part of the area of ​​the filter screen is wasted. And the filter screen in the prior art is mostly fixed by a slide groove set on the grille 2 or the housing 1, which results in that when the grille, the filter screen and the housing are assembled, the edge structure of the filter screen will partially block the air inlet 13, reducing the air intake to a certain extent.

[0060] In order to make the connection between the filter screen 3 and the grille 2 tighter and prevent the edge of the filter screen 3 from protruding from the connection, Figure 3 , Fig.12 As shown, the inner side of the grille 2 is also provided with a clamping hole 24, which is engaged with a clamping block 31 provided on the filter screen 3 to fix the filter screen 3 on the grille 2. Here, the inner side of the grille 2 is Figure 3 The side edge of the front side of the middle rear grille, that is, the latch hole 24 and the bridge structure 20 are located on the same side of the grille 2 .

[0061] In this way, by setting a clamping hole 24 at the inner side edge of the grille 2 and setting a clamping block 31 structure on the side of the filter 3, the filter 3 is fixed on the grille 2 through the clamping action of the clamping hole 24 and the clamping block 31, so as to avoid the filter 3 blocking part of the air inlet 13 and increase the air inlet area; at the same time, the exposure of the filter 3 is reduced, thereby improving the overall aesthetics of the product.

[0062] In order to improve the connection firmness between the filter 3 and the grille 2, there are multiple clamping holes 24, and multiple clamping holes 24 are distributed on the inner periphery of the grille 2; accordingly, the filter 3 has the same number of clamping blocks 31. And the center line of each clamping hole 24 is parallel to the plane where the side is located, ensuring that the filter 3 is located at the rear side of the grille 2 and parallel to the grille 2. Specifically, in the embodiment of the present invention, multiple clamping holes 24 are provided on the inner side of the upper side, left side and lower side of the rear grille 2, and the inner side of the upper side, lower side and front side of the right grille 2; wherein, the number of clamping holes 24 is not limited, subject to meeting the installation requirements.

[0063] In the above embodiment of the present invention, a plurality of latches 23 are provided at the edges of the front side of the right grille 2 and the lower side of the rear grille 2 to improve the connection stability of the grille 2, the filter 3 and the housing 1. Figure 3 As shown, the latches 23 and the latch holes 24 located on the same side of the grille 2 are arranged at intervals.

[0064] During the assembly process, the block 31 of the filter 3 is first inserted into the corresponding holes 24 in sequence to fix the filter 3 on the inner side of the grille 2; then the grille 2 is fixed to the housing 1 by means of the combined action of snapping and plugging. In order to prevent the filter 3 installed on the inner side of the grille 2 from blocking the bridge structure 20, the length of the block 31 on the filter 3 is usually greater than the maximum width of the bridge structure 20. Here, the length of the block 31 is Fig.12 The distance in the left and right directions of the block 31 located on the left side of the grille 2 is equal to the maximum width of the bridge structure 20. Fig.12 The maximum distance in the left-right direction of the bridge structure 20 located on the left side of the grille 2. That is, a gap is left between the side of the filter 3 and the bridge structure 20, so as not to affect the connection between the bridge structure 20 and the second buckle 11 of the housing 1.

[0065] It is understandable that since the grille 2 is located at the air inlet 13 of the housing 1 and is connected to the air duct, in order to prevent users, especially children, from accidentally removing the grille 2, which may cause safety hazards, the grille 2 and the housing 1 are also provided with screw fastening positions, including a first screw hole 25 provided on the grille 2 and a second screw hole 15 provided on the housing 1. After the buckle structures and the assembly structures are buckled and positioned, the grille 2 and the housing 1 are fastened by screws, thereby improving the safety of the air conditioner.

[0066] The present invention further provides an air conditioner, including the above-mentioned snap-fit ​​structure between the grille and the shell. Compared with the existing snap-fit ​​structure, the design is simple, and the snap-fit ​​part itself and the snap-fitting part are not effectively protected. The embodiment of the present invention optimizes the design of the snap-fit ​​structure, that is, the snap-fit ​​structure between the grille and the shell provided includes a bridge structure arranged on the grille 2, the bridge structure 20 includes a bridge portion 22 and a first snap 21, the bridge portion 22 is provided with a first through hole 221, and at least a portion of the first snap 21 is located in the first through hole 221.

[0067] By providing the bridging portion 22, not only the overall structural strength of the buckle structure can be improved; during the loading and unloading process, the bridging portion 22 can also share part of the force to prevent the first buckle 21 from being damaged due to stress concentration, thereby effectively protecting the first buckle 21 and preventing the first buckle 21 from being squeezed and collided by other components during the production, transportation, or loading and unloading of the air conditioner, thereby preventing the risk of breakage or fragmentation.

[0068] The present invention is disclosed as above, but the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, so the protection scope of the present invention shall be subject to the scope defined by the claims.
