Description

Technical Field

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

[0002] Existing air conditioner indoor units are equipped with insulation materials, such as foam materials, at the air outlet channel. These materials are directly attached to the shell of the air conditioner indoor unit. During the start and stop of the air conditioner, or during heating or cooling, the foam material and the shell are made of different materials, and the amount of contraction and expansion in the linear direction of the two are different, resulting in friction between the two due to relative movement, causing abnormal noise.

[0003] At present, the existing technology usually adopts the method of sticking flannel and applying lubricating oil to solve this abnormal noise, but the flannel needs to be set manually, which is difficult to realize automatic production, reducing the production efficiency of the air conditioner. Some abnormal noises are caused by tight fit between parts, such as the indoor unit panel body and the bottom shell, which are often connected and fixed with screws. After thermal expansion and contraction, they cannot be released freely, which affects the clearance of the fitting position and the deformation of parts, resulting in continuous abnormal noise.

[0004] There is an existing air conditioner indoor unit, in which a panel body and a bottom shell are connected by a plurality of fixing structures, and the fixing structures located outside the edge of the panel body provide a play gap between the panel body and the bottom shell that enables the bottom shell to move relative to the panel body in three-dimensional directions, and the fixing structures located in the middle of the panel body securely connect the panel body and the bottom shell. In this way, when the bottom shell expands or contracts, the edge of the bottom shell moves relative to the panel body through the play gap to release the internal stress generated by the expansion and contraction, and eliminate the abnormal sound generated by the expansion and contraction. However, since the play gap enables the bottom shell to move relative to the panel body in all directions, the panel body and the bottom shell are only fixed by the fixing structure in the middle, which may cause the problem of unstable connection between the panel body and the bottom shell. Utility Model Content

[0005] The first purpose of the utility model is to provide an air conditioner casing that can freely release the size changes of parts of the panel body and the bottom shell under the state of thermal expansion and contraction, solve the abnormal noise between the parts, and at the same time ensure the stable connection between the panel body and the bottom shell.

[0006] The second object of the utility model is to provide an air-conditioning indoor unit having the air-conditioning casing.

[0007] The third object of the utility model is to provide an air conditioner having the above-mentioned air conditioner indoor unit.

[0008] To achieve the above-mentioned first purpose, the utility model provides an air-conditioning casing, which includes a panel body and a bottom shell, the panel body cover is arranged on the bottom shell, and the panel body and the bottom shell are connected by a fixing structure; the fixing structure includes a first fixing component and a second fixing component; the first fixing component is arranged near the middle of the length direction of the air-conditioning casing, and the first fixing component fixes the bottom shell in a three-dimensional direction relative to the panel body; the second fixing component is arranged near the end of the length direction of the air-conditioning casing, and the second fixing component fixes the panel body and the bottom shell in a front-to-back direction, and provides a movable gap between the bottom shell and the panel body that enables the bottom shell to move relative to the panel body in a direction perpendicular to the front-to-back direction.

[0009] It can be seen from the above scheme that the experiment found that under the environment of thermal expansion and contraction, the size change of the panel body and the bottom shell in the left-right direction is the largest, followed by the up-down direction, and the size change in the front-to-back direction is the smallest. The air-conditioning casing of the utility model is arranged in the middle part to fix the bottom shell and the panel body in three-dimensional directions to achieve positioning between the two. At the same time, a second fixing component is arranged to fix the panel body and the bottom shell in the front-to-back direction, and there is a movable gap between the bottom shell and the panel body to enable the bottom shell to move relative to the panel body in a direction perpendicular to the front-to-back direction. When the bottom shell is deformed due to thermal expansion and contraction, since there is almost no change in the front-to-back direction, the second fixing component can limit the panel body and the bottom shell in the front-to-back direction to ensure the stability of the connection between the two. At the same time, through the setting of the movable gap, it is ensured that the bottom shell moves relative to the panel body in a direction perpendicular to the front-to-back direction, thereby releasing the internal stress caused by thermal expansion and contraction and eliminating abnormal noise caused by thermal expansion and contraction.

[0010] A preferred solution is that the first fixing component includes a positioning boss, a positioning column and a first fixing piece; the positioning boss is located on the panel body, a positioning groove is provided on the end wall of the positioning boss, and a panel body fixing hole extending along the length direction of the positioning boss is provided on the bottom wall of the positioning groove; the positioning column is located on the bottom shell, a bottom shell fixing hole extending along the length direction of the positioning column is provided on the positioning column, and the positioning column is plugged into the positioning groove; the first fixing piece passes through the panel body fixing hole and the bottom shell fixing hole to fasten the bottom shell and the panel body.

[0011] It can be seen that the pre-positioning between the panel body and the bottom shell can be achieved through the plug-in cooperation between the positioning column and the positioning groove, and the stability of the first fixing component in fastening the panel body and the bottom shell can be further improved.

[0012] A further solution is that the matching surface of at least one of the positioning post and the positioning groove is a rough surface.

[0013] It can be seen from this that the roughness of the mating surface can be increased, thereby increasing the friction between the two and improving the tightness of the connection.

[0014] A preferred solution is that the second fixing assembly includes a lever, a first limiting portion and a second limiting portion; the first limiting portion is located on the panel body, the first limiting portion includes a first limiting hole and a clamping column, and the clamping column extends in the front-to-back direction; the lever includes a rod body and a rod head arranged along the left-right direction, a positioning hole is provided on the rod body, the rod body is sleeved on the clamping column through the positioning hole and cooperates with the clamping column in the front-to-back direction, and the rod body and the positioning hole are clearance-fitted perpendicular to the front-to-back direction; the second limiting portion is located on the bottom shell, the second limiting portion includes a second limiting hole; the first limiting hole and the second limiting hole are both arranged opposite to the rod head in the left-to-right direction, and the rod head can pass through the first limiting hole and the second limiting hole in sequence along the left-to-right direction to connect the panel body with the bottom shell.

[0015] It can be seen that, by setting the lever, the assembly process can be simplified and the assembly efficiency can be improved compared with fixing parts such as screws. At the same time, the lever can achieve tightening only in the front-to-back direction.

[0016] A further solution is that the rod head and the first limiting hole are matched with each other in the front-rear direction, and the rod head and the first limiting hole are matched with each other in the up-down direction.

[0017] It can be seen that this enables the lever to swing at a small angle in the up and down directions.

[0018] A further solution is that the rod head is cylindrical; the first limiting hole is a waist-shaped hole, and the first limiting hole extends along the up and down direction; the second limiting hole is a round hole, and the rod head and the second limiting hole are interference fit.

[0019] It can be seen that the round hole can fit closely with the rod head to achieve the fixation of the panel body and the bottom shell in the front-to-back direction, and the waist-shaped hole can achieve the relative fixation of the panel body and the bottom shell in the front-to-back direction and the relative movement in the up-down direction.

[0020] A further solution is that the positioning hole includes an assembly position hole, a connecting hole and a fixed position hole which are arranged in sequence along the length direction of the rod body, and the assembly position hole, the connecting hole and the fixed position hole gradually move away from the rod head; a limiting protrusion is provided at the end of the clamping column, and the limiting protrusion protrudes from the outer peripheral wall of the clamping column along the radial direction of the clamping column, and the limiting protrusion limits the lever in the front and rear directions, the size of the assembly position hole is larger than the size of the limiting protrusion, and the size of the fixed position hole is smaller than the size of the limiting protrusion; when the clamping column cooperates with the assembly position hole, the rod head is located outside the first limiting hole and the second limiting hole, and the lever is in the unlocking position; when the clamping column cooperates with the fixed position hole, the rod head is inserted into the first limiting hole and the second limiting hole, and the lever is in the locking position.

[0021] It can be seen that the lever moves along the left and right directions, thereby realizing the movement of the clamping column relative to the positioning hole along the extension direction of the positioning hole. During assembly, the assembly position hole of the lever can be first aligned with the clamping column to put the lever on the clamping column, and then the lever is moved along the left and right directions so that the rod head passes through the first limit hole and the second limit hole. At this time, the lever is in a locked position. In this position, the bottom shell has a certain movable space relative to the panel body in the up and down and left and right directions, and there is no movable gap in the front and back directions.

[0022] A further solution is that guide surfaces are provided on both sides of the assembly position hole near the connecting hole, and the guide surfaces gradually move away from the wall panel from the end farthest from the connecting hole to the end close to the connecting hole. The wall panel is the part of the panel body on which the first limiting portion is provided, and the limiting protrusion and the guide surface slide in cooperation in the moving direction of the lever.

[0023] It can be seen that by providing the guide surface, the lever is facilitated to move from the position where the assembly position hole cooperates with the clamping column to the position where the connection hole cooperates with the clamping column.

[0024] A preferred solution is that a shift block is provided on one end of the rod body away from the rod head, and an opening is provided on the wall panel of the panel body provided with a first limiting portion, the opening penetrates the wall panel in the front-to-back direction, and the shift block passes through the opening and extends to the side of the wall panel away from the first limiting portion.

[0025] It can be seen that the provision of the opening makes it easier for workers to move the lever at the front side of the panel body, thereby improving assembly efficiency.

[0026] A further solution is that a supporting protrusion is further provided on the wall plate, the supporting protrusion extends in the left-right direction, the rod body is in linear contact with the supporting protrusion and slides along the extending direction of the supporting protrusion.

[0027] It can be seen that the provision of the supporting protrusion can reduce the contact area between the lever and the panel body, thereby reducing friction and reducing abnormal noise generated when the lever slides relative to the panel body due to thermal expansion and contraction.

[0028] A preferred solution is that the material of the lever is a polymer self-lubricating material; or the lever is coated with a lubricating coating.

[0029] It can be seen that by further reducing the friction between the lever and the panel body, the abnormal noise when the two move relative to each other can be reduced.

[0030] A preferred solution is that the number of second fixing components is two, and the two second fixing components are respectively arranged near the two ends of the length direction of the air-conditioning casing, and the two second fixing components are symmetrically arranged with the first plane as the center, and the first plane passes through the midpoint of the length direction of the air-conditioning casing and is perpendicular to the length direction of the air-conditioning casing.

[0031] It can be seen that the two second fixing components are respectively arranged at the two ends of the length direction of the air conditioner casing, so that the panel body and the bottom shell can be fixed from both ends to ensure the stability of the connection between the two.

[0032] A preferred solution is that an air outlet is opened on the bottom shell, and the first fixing component is located above the air outlet and arranged close to the air outlet.

[0033] It can be seen from this that the bottom shell and the panel body can be tightly connected near the air outlet, thereby avoiding a gap between the two near the air outlet to affect the air outlet.

[0034] A further solution is that the fixing structure also includes a third fixing component, which is located below the air outlet and close to the middle of the length direction of the air-conditioning casing; the third fixing component includes a first fixing hole, a second fixing hole and a second fixing piece, the first fixing hole is located on the panel body, the second fixing hole is located on the bottom shell, and the second fixing piece passes through the first fixing hole and the second fixing hole to fasten the panel body and the bottom shell together.

[0035] It can be seen that the third fixing component cooperates with the first fixing component to realize the positioning and fastening connection of the bottom shell and the panel body in the middle of the air conditioner casing.

[0036] A preferred solution is that the fixing structure also includes a fourth fixing component, which is located on the top of the air-conditioning casing; the fourth fixing component includes a card hole and a buckle, the buckle is located on the bottom shell, the card hole is located on the panel body, and the buckle is inserted into the card hole from bottom to top; the buckle and the card hole are tightly matched in the front-to-back direction, and the buckle and the card hole are gap-fitted in the left-right direction.

[0037] It can be seen that the fourth fixing component can connect the bottom shell and the panel body at the top of the air-conditioning casing, the buckle and the card hole are plugged in and matched along the up and down directions, and the buckle and the card hole are gap-fitted in the left and right directions, so that the buckle of the bottom shell has room for movement relative to the card hole of the panel body in the up and down directions and the left and right directions.

[0038] A preferred solution is that the number of the fourth fixing components is more than two, and the plurality of fourth fixing components are arranged at intervals along the length direction of the air conditioner casing.

[0039] It can be seen that the plurality of fourth fixing components are arranged at intervals along the length direction of the air conditioner casing, which can improve the stable connection between the top and bottom shells of the air conditioner casing and the panel body.

[0064] See also Figure 1 and Figure 2 The air conditioner of this embodiment includes an air conditioner outdoor unit and an air conditioner indoor unit connected to each other. The air conditioner indoor unit includes an air conditioner housing 1, a heat exchanger 21, a fan (not shown), an air guide assembly 22, etc. The heat exchanger 21 and the fan are both installed in the air conditioner housing 1.

[0065] The air conditioner casing 1 includes a panel 11, a panel body 12 and a bottom shell 13. The panel body 12 is covered on the bottom shell 13. The panel 11 is arranged on the front side of the panel body 12 and is hinged to the panel body 12. The panel body 12 and the bottom shell 13 are connected by a fixing structure 3.

[0066] The fixing structure 3 includes a first fixing component 4 , a second fixing component 5 , a third fixing component 6 and a fourth fixing component 7 .

[0067] The air conditioner housing 1 extends in the left-right direction, and the first fixing assembly 4 is arranged near the middle of the length direction of the air conditioner housing 1. The first fixing assembly 4 fixes the bottom shell 13 in a three-dimensional direction relative to the panel body 12. An air outlet 131 is provided on the bottom shell 13, the air guide assembly 22 is arranged at the air outlet 131, and the first fixing assembly 4 is located above the air outlet 131 and arranged near the air outlet 131.

[0068] See also Figure 3 , Figure 8 and Fig.12 The first fixing assembly 4 includes a positioning boss 41, a positioning column 42 and a first fixing member (not shown). The positioning boss 41 is located on the panel body 12. A positioning groove 411 is provided on the end wall of the positioning boss 41. A panel body fixing hole 412 extending along the length direction of the positioning boss 41 is provided on the bottom wall of the positioning groove 411.

The first fixing member passes through the panel body fixing hole 412 and the bottom shell fixing hole 421 to fasten the bottom shell 13 and the panel body 12. The pre-positioning between the panel body 12 and the bottom shell 13 can be achieved by plugging and fitting the positioning column 42 into the positioning groove 411. At the same time, after the positioning column 42 is fitted into the positioning groove 411, the stability of the first fixing component 4 in fastening the panel body 12 and the bottom shell 13 can be further improved by fastening them with the first fixing member.

[0069] In addition, if Fig.12 As shown, the mating surface on at least one of the positioning column 42 and the positioning groove 411 is a rough surface. Specifically, fine textures or small ribs can be set on the mating surface to increase the roughness of the mating surface, thereby increasing the friction between the two and improving the tightness of the connection. In this embodiment, the rough mating surface is located on the outer surface of the positioning column 42.

[0070] like Figure 2 As shown, the number of the second fixing components 5 is two, and the two second fixing components 5 are respectively arranged near the two ends in the length direction of the air-conditioning housing 1, and the two second fixing components 5 are symmetrically arranged with the first plane as the center, and the first plane passes through the midpoint in the length direction of the air-conditioning housing 1 and is perpendicular to the length direction of the air-conditioning housing 1. The two second fixing components 5 are respectively arranged near the two ends in the length direction of the air-conditioning housing 1, and the panel body 12 and the bottom shell 13 can be fixed from both ends to ensure the stability of the connection between the two.

[0071] In addition, the second fixing assembly 5 can fix the panel body 12 and the bottom shell 13 in the front-to-back direction, and provide a movable gap between the bottom shell 13 and the panel body 12 to enable the bottom shell 13 to move relative to the panel body 12 in a direction perpendicular to the front-to-back direction.

[0072] See also Figure 2 , Figure 4 , Figure 5 , Figure 7 and Fig. 9 As shown, the second fixing assembly 5 includes a lever 51, a first limiting portion 52 and a second limiting portion 53. The first limiting portion 52 is located on the panel body 12 and includes a first limiting hole 521 and a clamping column 522, and the clamping column 522 extends in the front-rear direction.

[0073] See also Figures 9 to 16 The lever 51 includes a rod body 511 and a rod head 512 arranged along the left-right direction. A positioning hole 510 is provided on the rod body 511. The rod body 511 is sleeved on the clamping column 522 through the positioning hole 510 and is engaged with the clamping column 522 in the front-to-back direction. The rod body 511 and the positioning hole 510 are clearance-matched perpendicular to the front-to-back direction. Here and hereinafter, "clearance-matched" means that there is a relative movable gap between the two.

[0074] The second limiting portion 53 is located on the bottom shell 13, and the second limiting portion 53 includes a second limiting hole 531. The first limiting hole 521 and the second limiting hole 531 are both arranged opposite to the rod head 512 in the left and right directions. The rod head 512 can pass through the first limiting hole 521 and the second limiting hole 531 in sequence along the left and right directions to connect the panel body 12 with the bottom shell 13.

[0075] The rod head 512 and the first limiting hole 521 are limited in the front-to-back direction, and the rod head 512 and the first limiting hole 521 are clearance-matched in the up-down direction, so that the lever 51 can swing at a small angle in the up-down direction. In this embodiment, the rod head 512 is cylindrical, the first limiting hole 521 is a waist-shaped hole, the first limiting hole 521 extends in the up-down direction, the second limiting hole 531 is a round hole, and the rod head 512 and the second limiting hole 531 are interference-matched. The round hole can be closely matched with the rod head 512 to achieve the fixation of the panel body 12 and the bottom shell 13 in the front-to-back direction, and the waist-shaped hole can achieve the relative fixation of the panel body 12 and the bottom shell 13 in the front-to-back direction and the relative movement in the up-down direction.

[0076] The positioning hole 510 includes an assembly position hole 514, a connection hole 515 and a fixed position hole 516 which are sequentially arranged along the length direction of the rod body 511. The assembly position hole 514, the connection hole 515 and the fixed position hole 516 are gradually away from the rod head 512. A limiting protrusion 523 is provided at the end of the clamping column 522. The limiting protrusion 523 protrudes from the outer peripheral wall of the clamping column 522 along the radial direction of the clamping column 522. The limiting protrusion 523 limits the lever 51 in the front-rear direction. The size of the assembly position hole 514 is larger than the size of the limiting protrusion 523, and the size of the fixed position hole 516 is smaller than the size of the limiting protrusion 523. When the clamping column 522 is matched with the assembly position hole 514, the rod head 512 is located outside the first limiting hole 521 and the second limiting hole 531, and the lever 51 is in the unlocking position; when the clamping column 522 is matched with the fixed position hole 516, the rod head 512 is inserted into the first limiting hole 521 and the second limiting hole 531, and the lever 51 is in the locking position. Therefore, the lever 51 moves along the left-right direction, thereby realizing the movement of the clamping column 522 relative to the positioning hole 510 along the extension direction of the positioning hole 510. During assembly, the assembly position hole 514 of the lever 51 can be first aligned with the clamping column 522 to sleeve the lever 51 on the clamping column 522, and then the lever 51 is moved along the left-right direction so that the rod head 512 passes through the first limiting hole 521 and the second limiting hole 531. At this time, the lever 51 is in the locking position, and the upper bottom shell 13 has a certain activity space relative to the panel body 12 in the up-down and left-right directions, and there is no activity gap in the front-back direction.

[0077] In addition, guide surfaces 517 are provided on both sides of the assembly position hole 514 near the connection hole 515. From the end away from the connection hole 515 to the end close to the connection hole 515, the guide surfaces 517 gradually move away from the wall plate 121. The wall plate 121 is the part of the panel body 12 where the first limiting portion 52 is provided. The limiting protrusion 523 and the guide surface 517 are slidably matched in the moving direction of the lever 51. The guide surface 517 is provided to facilitate the lever 51 to move from the position where the assembly position hole 514 and the clamping column 522 are matched to the position where the connection hole 515 and the clamping column 522 are matched.

[0078] A shift block 513 is provided on one end of the rod body 511 away from the rod head 512, and an opening 122 is provided on the wall panel 121 on which the first limiting portion 52 is provided on the panel body 12. The opening 122 extends along the left-right direction and penetrates the wall panel 121 in the front-back direction. The shift block 513 passes through the opening 122 and extends to the side of the wall panel 121 away from the first limiting portion 52.

[0079] The wall plate 121 is also provided with a support protrusion 123, which extends in the left-right direction. The rod body 511 is in line contact with the support protrusion 123 and slides along the extension direction of the support protrusion 123. Each lever 51 is supported for sliding by two support protrusions 123 arranged at intervals along the width direction of the lever 51. The provision of the support protrusion 123 can reduce the contact area between the lever 51 and the panel body 12, thereby reducing friction and reducing abnormal noise generated when the lever 51 slides relative to the panel body 12 due to thermal expansion and contraction.

[0080] Preferably, the material of the lever 51 is a polymer self-lubricating material, or the lever 51 is coated with a lubricating coating, so as to further reduce the friction between the lever 51 and the panel body 12, thereby reducing abnormal noise when the two move relative to each other.

[0081] The third fixing assembly 6 is located below the air outlet 131 and is arranged near the middle of the length direction of the air conditioner housing 1. The third fixing assembly 6 includes a first fixing hole 61, a second fixing hole 62, and a second fixing piece. The first fixing hole 61 is located on the panel body 12, and the second fixing hole 62 is located on the bottom shell 13. The second fixing piece passes through the first fixing hole 61 and the second fixing hole 62 to fasten the panel body 12 and the bottom shell 13. The third fixing assembly 6 cooperates with the first fixing assembly 4 to realize the positioning and fastening connection of the bottom shell 13 and the panel body 12 in the middle of the air conditioner housing 1.

[0082] like Figure 2 As shown, the fourth fixing component 7 is located at the top of the air-conditioning housing 1. The fourth fixing component 7 includes a clamping hole 71 and a buckle 72. The buckle 72 is located on the bottom shell 13, and the clamping hole 71 is located on the panel body 12. The buckle 72 is inserted into the clamping hole 71 from bottom to top. The buckle 72 and the clamping hole 71 are tightly matched in the front-to-back direction, and the buckle 72 and the clamping hole 71 are clearance matched in the left-right direction. The fourth fixing component 7 can connect the bottom shell 13 and the panel body 12 at the top of the air-conditioning housing 1. The buckle 72 and the clamping hole 71 are plug-fitted in the up-down direction, and the buckle 72 and the clamping hole 71 are clearance matched in the left-right direction, so that the buckle 72 of the bottom shell 13 has room for movement in both the up-down direction and the left-right direction relative to the clamping hole 71 of the panel body 12.

[0083] The number of the fourth fixing components 7 is more than two, and the plurality of fourth fixing components 7 are arranged at intervals along the length direction of the air conditioner housing 1. Preferably, in this embodiment, the number of the fourth fixing components 7 is three. The plurality of fourth fixing components 7 are arranged at intervals along the length direction of the air conditioner housing 1, which can improve the stable connection between the top bottom shell 13 of the air conditioner housing 1 and the panel body 12.

[0084] As can be seen from the above, the test found that under the environment of thermal expansion and contraction, the size change of the panel body and the bottom shell in the left-right direction is the largest, followed by the up-down direction, and the size change in the front-to-back direction is the smallest. The air-conditioning casing of the utility model is arranged in the middle part to fix the bottom shell and the panel body in three-dimensional directions to achieve positioning between the two. At the same time, a second fixing component is arranged to fix the panel body and the bottom shell in the front-to-back direction, and there is a movable gap between the bottom shell and the panel body to enable the bottom shell to move relative to the panel body in a direction perpendicular to the front-to-back direction. When the bottom shell is deformed due to thermal expansion and contraction, since there is almost no change in the front-to-back direction, the second fixing component can limit the panel body and the bottom shell in the front-to-back direction to ensure the stability of the connection between the two. At the same time, through the setting of the movable gap, it is ensured that the bottom shell moves relative to the panel body in a direction perpendicular to the front-to-back direction, thereby releasing the internal stress caused by thermal expansion and contraction, and eliminating abnormal noise caused by thermal expansion and contraction.

[0085] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
