Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a filter screen fixing structure, an air conditioner indoor unit with the filter screen fixing structure, and an air conditioner with the air conditioner indoor unit. Background Art

[0002] An air conditioner is an air conditioning device that allows the air in the environment to exchange heat with its own evaporator to adjust the ambient temperature. That is, when the air in the environment exchanges heat with the air conditioner evaporator, the air will pass through the evaporator under the action of the running fan blades to exchange heat with it. In order to extend the service life of the air conditioner and maintain the heat exchange performance of the air conditioner, the filter plays a key role. It can filter out impurities in the air to maintain the cleanliness of the key components inside the air conditioner, thereby ensuring the heat exchange performance of the air conditioner.

[0003] As the usage time increases, a lot of dust and dirt will accumulate on the filter, which is likely to produce a large number of harmful substances such as bacteria or viruses. These harmful substances circulate in the room with the air, polluting the air, spreading diseases, and seriously endangering human health. In addition, dirt will increase air circulation resistance and increase heat exchange energy consumption. Therefore, the air conditioner filter needs to be disassembled, replaced or cleaned regularly.

[0004] Especially the kitchen air conditioner, as an air conditioner used in special scenes in the kitchen, when people are stir-frying and cooking in the kitchen, a large amount of fumes will escape in the kitchen. In order to prevent the escaping fumes from entering the air conditioner and causing the air conditioner performance to decline, the filter on the kitchen air conditioner plays a more prominent role. For this reason, the filter of the kitchen air conditioner needs to be cleaned regularly or replaced more frequently to maintain the heat exchange performance of the kitchen air conditioner.

[0005] When the filter is replaced or cleaned, in order to facilitate the removal of the filter from the air conditioner casing, an elastic component is currently provided at the bottom of the filter, which elastic component includes a push rod spring and a push rod. When the push rod spring abuts against the filter frame, the buckle is opened and the push rod spring is released to lift the filter frame, eliminating the need for the user to manually lift the filter frame, thereby facilitating the removal of the filter. At this time, the push rod spring is disassembled from the filter frame. However, when reinstalling the filter, it is necessary to first install the push rod and the push rod spring, and then press the buckle of the filter into the slot on the air conditioner casing, which makes the filter installation operation complicated, thereby resulting in the filter installation operation being not convenient enough. Utility Model Content

[0006] In order to achieve the first purpose of the utility model, the utility model provides a filter fixing structure that can make the filter disassembly and assembly operation simpler and more convenient, thereby facilitating users to clean and replace the filter, thereby improving the user experience.

[0007] In order to achieve the second purpose of the utility model, the utility model provides an air-conditioning indoor unit with the above-mentioned filter fixing structure.

[0008] In order to achieve the third purpose of the utility model, the utility model provides an air conditioner having the above-mentioned air conditioner indoor unit.

[0009] In order to achieve the first purpose of the utility model, the utility model provides a filter fixing structure, including a shell and a filter, a first end of the supporting surface of the shell is provided with a limiting groove, and a second end of the supporting surface is provided with a limiting member, the limiting member includes an elastic buckle arm and a convex buckle, the first end of the elastic buckle arm is connected to the supporting surface, and the convex buckle is provided at the second end of the elastic buckle arm, the filter can be placed and supported on the supporting surface, the first end of the filter can be inserted into the limiting groove, and the convex buckle can be hooked on the side of the second end of the filter away from the supporting surface, the first end of the filter is arranged opposite to the second end of the filter, and the supporting surface is provided with an elastic resist arm between the limiting groove and the limiting member, the first end of the elastic resist arm is connected to the supporting surface, and the second end of the elastic resist arm extends away from the supporting surface and can be pressed on the side of the filter bracket close to the supporting surface to force the filter to move away from the supporting surface.

[0010] It can be seen from the above scheme that when the filter screen fixing structure of the utility model is installed on the shell, the first end of the filter screen is first inserted into the limiting groove arranged at the first end of the supporting surface of the shell, so that the limiting groove limits the first end of the filter screen to the supporting surface of the shell, and then the elastic buckle arm of the limiting member is moved so that the second end of the filter screen is placed and supported on the supporting surface of the shell, and then the elastic buckle arm of the limiting member is released so that the convex buckle of the limiting member is hooked on the side of the second end of the filter screen away from the supporting surface, so that the limiting member limits the second end of the filter screen to the supporting surface of the shell, thereby achieving the purpose of simply and conveniently installing the filter screen. At this time, the second end of the elastic support arm on the supporting surface of the shell is pressed against the side of the filter screen bracket close to the supporting surface, and because the first end of the filter screen of the utility model is relatively arranged with the second end of the filter screen, the limiting groove and the limiting member on the supporting surface of the shell can firmly limit the filter screen as a whole to the supporting surface of the shell, thereby improving the stability of the filter screen installation.

[0011] When the filter fixing structure of the utility model is removed from the shell, the elastic buckle arm of the limiting member is pushed to make the convex buckle detach from the second end of the filter. Since the second end of the elastic supporting arm on the supporting surface of the shell presses against the side surface of the bracket of the filter close to the supporting surface, the second end of the elastic supporting arm can force the filter to move away from the supporting surface when the convex buckle detaches from the second end of the filter. Since the elastic supporting arm extends away from the supporting surface, the elastic supporting arm has a good elastic forcing restoring force, so that the elastic supporting arm quickly pops the filter out of the supporting surface of the shell, and the user does not need to manually lift the filter from the supporting surface of the shell, thereby achieving the purpose of simply and conveniently removing the filter.

[0012] Therefore, the filter fixing structure of the utility model can achieve the purpose of making the filter disassembly and assembly operation simpler and more convenient, so as to facilitate the user to clean and replace the filter, thereby improving the user experience. In addition, the limit groove, limit member and elastic arm of the filter fixing structure of the utility model can be integrally injection molded with the shell as one part, without adding additional molds, thereby saving production costs.

[0013] A further solution is that a first limiting wall is provided at the first end of the supporting surface, the first end of the first limiting wall is connected to the shell, the second end of the first limiting wall extends obliquely away from the supporting surface, and a limiting groove is formed between the first limiting wall and the supporting surface.

[0014] A further solution is that the second end of the first limiting wall is connected to a second limiting wall, and one end of the second limiting wall away from the first limiting wall extends obliquely away from the support surface, and the inclination angle between the second limiting wall and the support surface is greater than the inclination angle between the first limiting wall and the support surface.

[0015] A further solution is that the first end of the elastic support arm is connected to the support surface through an elastic connecting arm, and the elastic connecting arm is arranged to be inclined away from the support surface.

[0016] A further solution is that an elastic cantilever is connected between the elastic connecting arm and the elastic supporting arm, and the elastic cantilever extends parallel to the supporting surface.

[0017] A further solution is that the first end of the elastic support arm is connected to the support surface through an elastic arc arm.

[0018] A further solution is that the bending direction of the elastic arc-shaped arm is arranged toward or away from the supporting surface.

[0019] In order to achieve the second purpose of the utility model, the utility model provides an air-conditioning indoor unit, including a filter fixing structure, and the filter fixing structure is the above-mentioned filter fixing structure.

[0020] A further solution is that the air conditioner indoor unit also includes a panel, and a magnetic attraction part is arranged on the supporting surface of the shell of the filter fixing structure. The panel can cover the side of the filter of the filter fixing structure away from the supporting surface, and the magnetic attraction part can adsorb the panel or the magnetic part on the panel.

[0034] See also Figures 1 to 9The present embodiment discloses an air conditioner indoor unit 10, comprising a filter fixing structure. The filter fixing structure of the present embodiment comprises a housing 11 and a filter 12, a first end of a support surface 111 of the housing 11 is provided with a limiting groove 112, a second end of the support surface 111 of the housing 11 is provided with a limiting member 115, the limiting member 115 comprises an elastic buckle arm 1151 and a convex buckle 1152, the first end of the elastic buckle arm 1151 is connected to the support surface 111 of the housing 11, the convex buckle 1152 is provided at the second end of the elastic buckle arm 1151, the filter 12 of the present embodiment can be placed and supported on the support surface 111 of the housing 11, the first end of the filter 12 can be inserted into the limiting groove 112, the convex buckle 1152 can be hooked on the side of the second end of the filter 12 away from the support surface 111, and the first end of the filter 12 is arranged opposite to the second end of the filter 12. In addition, in the present embodiment, an elastic arm 161 is provided on the support surface 111 of the shell 11 between the limiting groove 112 and the limiting member 115, and the first end of the elastic arm 161 is connected to the support surface 111 of the shell 11, and the second end of the elastic arm 161 extends obliquely away from the support surface 111 of the shell 11 and can be pressed against the side of the bracket of the filter 12 close to the support surface 111, so as to force the filter 12 to move away from the support surface 111 of the shell 11.

[0035] When the filter screen fixing structure of this embodiment is installed on the shell 11, the first end of the filter screen 12 is first inserted into the limiting groove 112 set at the first end of the support surface 111 of the shell 11, so that the limiting groove 112 limits the first end of the filter screen 12 on the support surface 111 of the shell 11, and then the elastic buckle arm 1151 of the limiting member 115 is moved to place the second end of the filter screen 12 on the support surface 111 of the shell 11, and then the elastic buckle arm 1151 of the limiting member 115 is released to make the convex buckle 1152 of the limiting member 115 hooked on the side of the second end of the filter screen 12 away from the support surface 111, as shown in FIG. Figure 2 As shown, the limiting member 115 limits the second end of the filter 12 on the supporting surface 111 of the shell 11, thereby achieving the purpose of simply and conveniently installing the filter 12. At this time, the second end of the elastic arm 161 on the supporting surface 111 of the shell 11 is pressed against the side of the bracket of the filter 12 close to the supporting surface 111, and because the first end of the filter 12 and the second end of the filter 12 are arranged opposite to each other in this embodiment, the limiting groove 112 and the limiting member 115 on the supporting surface 111 of the shell 11 can firmly limit the filter 12 as a whole on the supporting surface 111 of the shell 11, thereby improving the stability of the installation of the filter 12.

[0036] When the filter screen fixing structure of this embodiment is to be removed from the housing 11, the elastic buckle arm 1151 of the limiter 115 is toggled to make the convex buckle 1152 detach from the second end of the filter screen 12. Since the second end of the elastic arm 161 on the supporting surface 111 of the housing 11 presses against the side of the bracket of the filter screen 12 close to the supporting surface 111, when the convex buckle 1152 detaches from the second end of the filter screen 12, the second end of the elastic arm 161 can force the filter screen 12 to move away from the supporting surface 111. Figure 4 As shown, since the elastic arm 161 extends away from the supporting surface 111, the elastic arm 161 has a good elastic forced restoring force, so that the elastic arm 161 quickly pops the filter 12 out of the supporting surface 111 of the shell 11, and the user does not need to manually lift the filter 12 from the supporting surface 111 of the shell 11, thereby achieving the purpose of simply and conveniently removing the filter 12.

[0037] Therefore, the filter fixing structure of this embodiment can achieve the purpose of making the filter 12 easier to disassemble and assemble, thereby facilitating the user to clean and replace the filter 12, thereby improving the user experience. In addition, the limit groove 112, the limit member 115 and the elastic arm 161 of the filter fixing structure of this embodiment can be integrally injection molded with the housing 11 as one part, without the need to increase the number of molds, thereby saving production costs.

[0038] Specifically, the first end of the support surface 111 of the housing 11 of this embodiment is provided with a first limiting wall 113, the first end of the first limiting wall 113 is connected to the housing 11, the second end of the first limiting wall 113 extends obliquely away from the support surface 111, and a limiting groove 112 is formed between the first limiting wall 113 and the support surface 111. Since the second end of the first limiting wall 113 that forms the limiting groove 112 with the support surface 111 extends obliquely away from the support surface 111, the limiting groove 112 is in a bell-mouth shape, which facilitates the smooth insertion of the first end of the filter 12 into the limiting groove 112, thereby improving the simplicity and convenience of the installation of the filter 12.

[0039] In order to further improve the smoothness of inserting the first end of the filter 12 into the limiting groove 112 and the simplicity and convenience of installing the filter 12, the second end of the first limiting wall 113 in this embodiment is connected to the second limiting wall 114, and the second limiting wall 114 extends obliquely away from the support surface 111 at one end away from the first limiting wall 113, and the inclination angle between the second limiting wall 114 and the support surface 111 is greater than the inclination angle between the first limiting wall 113 and the support surface 111. The second limiting wall 114 plays a limiting and guiding role for the first end of the filter 12.

[0040] In order to improve the elastic deformation ability of the elastic arm 161, the first end of the elastic arm 161 of this embodiment is connected to the support surface 111 through an elastic connection arm 162, and the elastic connection arm 162 is arranged to be inclined away from the support surface 111. Further, in this embodiment, an elastic cantilever 163 is connected between the elastic connection arm 162 and the elastic arm 161, and the elastic cantilever 163 extends parallel to the support surface 111, thereby improving the elastic deformation ability of the elastic arm 161. Specifically, the elastic arm 161 of this embodiment extends away from the support surface 111 in an inclined or curved manner.

[0041] See also Fig.10 and Fig.11 In this embodiment, the first end of the elastic arm 161 is connected to the support surface 111 through the elastic arc arm 164, thereby improving the elastic deformation ability of the elastic arm 161. Specifically, the bending direction of the elastic arc arm 164 in this embodiment is set toward or away from the support surface 111.

[0042] In addition, the air conditioner indoor unit 10 of this embodiment further includes a panel (not marked), and a magnetic member 13 is provided on the support surface 111 of the housing 11 of the filter fixing structure. The panel can be covered on the side of the filter 12 of the filter fixing structure away from the support surface 111, and the magnetic member 13 can adsorb the panel or the magnetic member (not marked) on the panel, so that the panel and the housing 11 form a detachable fit, so as to disassemble and assemble the filter 12. When the panel is made of magnetic metal material, the magnetic member 13 on the support surface 111 of the housing 11 is directly adsorbed with the metal panel, so that the metal panel can be detachably fixed on the housing 11. If the panel is made of plastic material, a magnetic member needs to be provided on the plastic panel, and the magnetic member is adsorbed with the magnetic member 13 on the support surface 111 of the housing 11, so that the plastic panel can be detachably fixed on the housing 11.

[0043] The above embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles of the present invention should be included in the scope of the present invention patent application.
