Description

RELATED APPLICATIONS This application claims priority to Chinese patent applications filed on March 3, 2019, application number 201920267861.4, entitled "GUIDE RAIL STRUCTURE, FRAME ASSEMBLY, FRAME, AIR CONDITIONER INDOOR UNIT AND AIR CONDITIONER" and application number 201910159486.6, entitled "GUIDE RAIL STRUCTURE, FRAME ASSEMBLY, FRAME, AIR CONDITIONER INDOOR UNIT AND AIR CONDITIONER", the entire contents of which are incorporated by reference.

This application relates to the field of air conditioners, and in particular to a guide rail structure and a frame, a frame assembly to which the guide rail structure is applied, and an air conditioner indoor unit and an air conditioner to which the frame assembly or frame is applied.

Air conditioners (commonly known as air conditioners) are electrical appliances that are designed to provide treated air directly to an enclosed space or area. As people's demands for environmental comfort increase, the functions of air conditioners are becoming more and more abundant.
Conventional air conditioners include air conditioners with automatic filter cleaning function and air conditioners with manual filter cleaning. Air conditioners with automatic filter cleaning function do not usually have a guide rail structure for manually attaching the filter to the frame. The filter guide rail structure in the air conditioner with manual filter cleaning is usually integrally molded into the frame, making it impossible to attach the automatic filter cleaning assembly. As a result, the frames of the air conditioner with automatic filter cleaning function and the air conditioner with manual filter cleaning need to be processed using different frame molds, which leads to a decrease in mold utilization rate and a complicated production process, which increases production costs and reduces productivity.

The main objective of this application is to provide a guide rail structure that solves the problem that conventional frames cannot be manufactured using the same mold. In other words, by installing it on the frame of an air conditioner with an automatic filter cleaning function and an air conditioner with a manually cleaned filter, it is possible to improve the utilization rate and production efficiency of the frame mold, simplify the production process, and reduce production costs.

In this application, a guide rail structure 3 to be provided on a frame assembly 100 is proposed. In this application, the frame assembly 100 includes a frame 1, which can be provided on an air conditioner with an automatic filter cleaning function or an air conditioner in which the filter is manually washed. Specifically, the frame 1 has a frame structure or a cover structure, the frame 1 has an air intake 11, and the frame assembly 100 further includes an air intake grid 2 provided on the air intake 11. The air intake grid 2 and the frame 1 may be provided separately. That is, the air intake grid 2 is removably connected to the air intake 11 of the frame 1 by a removably connecting method such as a buckle connection, an insert connection fitting, a screw connection, or a pin connection, which is not limited here.

Referring to the illustrations of Figures 1, 2, 3, 5, 6, 8, 9 and 10 in combination, in the embodiment of the present application, the guide rail structure 3 includes a connection part 31, a first guide 32 and a second guide 33, the first guide 32 is provided on at least one side of the connection part 31, and one end of the first guide 32 is provided in an arc shape; the second guide 33 is provided on at least one side of the connection part 31 and is provided opposite the arc position of the first guide 32, the second guide 33 and the first guide 32 are combined with the connection part 31 to form a slide rail 34, and the guide rail structure 3 is removably connected to the frame 1.

It is understood that the removable connection method between the guide rail structure 3 and the frame 1 may be a buckle connection, an insert connection fitting, a screw connection, or a pin connection, etc. That is, the guide rail structure 3 realizes a removable connection with the frame 1 through the connection part 31 and/or the first guide 32 and/or the second guide 33. At this time, the connection part 31, the first guide 32, and the second guide 33 realize a removable connection with the frame 1 as a whole. In this embodiment, the connection part 31 may be a plate-like structure or a block structure, and the connection part 31 plays the role of mounting, fixing, supporting, and connecting. When the guide rail structure 3 is mounted on the frame 1, in order to avoid the connection part 31 affecting the intake amount of the intake port 11, the connection part 31 preferably has a plate-like structure, and in the intake port 11 of the frame 1, the extension direction of the connection part 31 is the same as the intake direction of the intake port 11, that is, the thickness direction of the connection part 31 is perpendicular to the intake direction.

Specifically, in order to make the guide rail structure 3 conform to the shape contour of the intake port 11 of the frame 1, the shape contour of the connection part 31 is the same as the shape contour of the intake port 11 of the frame 1, that is, when the guide rail structure 3 is attached to the intake port 11 of the frame 1, the connection part 31 is connected and abuts against the inner wall of the frame 1 and/or the intake grid. Of course, to facilitate the installation of the filter 500, the first guide 32 and the inner wall of the frame 1 and/or the intake grid form an installation space, and when the filter 500 is accommodated in this installation space, both sides of the filter 500 can abut against the first guide 32, the inner wall of the frame 1 and/or the intake grid.

The first guide 32 has one end in an arc shape, which is the same as the contour of the inner wall of the frame 1 and/or the air intake grid, and is advantageous in that the installation of the guide rail structure 3 at the air intake 11 of the frame 1 does not affect the installation of other components of the air conditioner. In order to smoothly install the filter 500 in the installation space, the second guide 33 and the first guide 32 are arranged opposite each other at the arc shape positions, and the second guide 33 and the first guide 32 are combined with the connection part 31 to form a slide rail 34, which makes it easy for the filter 500 to enter or exit the installation space through the slide rail 34, improving the installation efficiency.

In this embodiment, the arc structure of the second guide 33 is similar to that of the first guide 32, i.e., the second guide 33 and the first guide 32 have the same bending arc. That is, the distance between the corresponding points of the second guide 33 and the first guide 32 is equivalent or the same. The provision of the second guide 33 provides guidance for the filter 500, which is advantageous in preventing the filter 500 from being stuck or caught in the bent corner of the frame 1 during the process of installing the filter 500 in the installation space.

In this embodiment, the number of first guides 32 and second guides 33 provided on the surfaces of both opposing sides of the connection part 31 differs due to the difference in the mounting position of the guide rail structure 3 at the intake port 11 of the frame 1. As shown in Figures 1, 5 and 9, when the guide rail structure 3 is mounted midway at the intake port 11 of the frame 1, the first guides 32 and second guides 33 are provided on both opposing surfaces of the connection part 31. At this time, the first guides 32 on one side of the connection part 31 and the first guides 32 on the other side are provided opposite each other, and the second guides 33 on one side of the connection part 31 and the second guides 33 on the other side are provided opposite each other. As shown in Figures 2, 3, 6, 8 and 10, when the guide rail structure 3 is mounted at the left end or right end of the intake port 11 of the frame 1, both the first guides 32 and the second guides 33 are provided on only one side of the connection part 31.

In this embodiment, one guide rail structure 3, two guide rail structures 3, or three guide rail structures 3 are removably attached to the air intake 11 of the frame 1. When one guide rail structure 3 is removably attached to the air intake 11 of the frame 1, it can be understood that a first guide device 32 and a second guide device 33 are both provided on the opposing surfaces of the connection part 31 in the guide rail structure 3. That is, a slide rail 34 is formed on both opposing surfaces of the connection part 31, and at this time, a filter slide rail that is integrally provided on the frame 1 is formed at the left end or right end of the air intake 11 on the frame 1, and the filter slide rail is combined with the slide rail 34 and attached to the filter 500. When two guide rail structures 3 are detachably attached to the air intake 11 of the frame 1, i.e., when the guide rail structures 3 are attached to the left and right ends of the air intake 11 of the frame 1, a first guide tool 32 and a second guide tool 33 are provided on one surface of the connection part 31 of each guide rail structure 3, and at this time, the slide rails 34 of the two guide rail structures 3 are arranged to face each other, and the two opposing slide rails 34 of the two guide rail structures 3 are combined and attached to the filter 500. When three guide rail structures 3 are detachably attached to the air intake 11 of the frame 1, as shown in Figures 4 and 7, the guide rail structures 3 are attached to both the left and right ends of the air intake 11 of the frame 1. The first guide tool 32 and the second guide tool 33 are provided on both opposing surfaces of the connection part 31 of the guide rail structure 3 attached to the air intake 11 of the frame 1, i.e., the slide rails 34 are formed on both opposing surfaces of the connection part 31 of each guide rail structure 3. A first guide 32 and a second guide 33 are provided on the surface of one side of the connection part 31 of the guide rail structure 3 attached to the left and right ends of the intake port 11 of the frame 1. At this time, the slide rail 34 of the guide rail structure 3 attached to the left end of the intake port 11 of the frame 1 is combined with the slide rail 34 on one side of the connection part 31 of the guide rail structure 3 attached to the middle of the intake port 11 of the frame 1 to attach the filter 500. The slide rail 34 of the guide rail structure 3 attached to the right end of the intake port 11 of the frame 1 is combined with the slide rail 34 on the other side of the connection part 31 of the guide rail structure 3 attached to the middle of the intake port 11 of the frame 1 to attach the filter 500. In this way, the length of the filter 500 is reduced, and the problem of inconvenient attachment and detachment due to the filter 500 being too long is avoided.

The guide rail structure 3 of the present application is applied to the frame 1, and the guide rail structure 3 is provided as a single component that can be removably attached to the frame 1, so that the frame 1 manufactured using the same mold for the frame 1 can be used for both air conditioners with an automatic filter cleaning function and air conditioners in which the filter is manually washed, improving the utilization rate and production efficiency of the mold for the frame 1, simplifying the production process, and reducing production costs. In one embodiment, the guide rail structure 3 includes a connection portion 31, a first guide 32, and a second guide 33, and the first guide 32 and the second guide 33 are provided opposite each other and combined to form a slide rail 34, which is advantageous for mounting the filter 500 on the frame 1 through the slide rail 34 or for removing the filter 500 from the frame 1, etc., when the guide rail structure 3 is attached to the frame 1. In one embodiment, the guide rail structure 3 is removably connected to the frame 1 through the connection portion 31 and/or the first guide 32 and/or the second guide 33. This is advantageous for quick and stable installation and removal of the guide rail structure 100.

In one embodiment, as shown in Figs. 1, 2 and 3, the first guide 32 includes an arc-shaped segment 321 and an extension segment 322 connected to the arc-shaped segment 321, the second guide 33 is disposed opposite the arc-shaped segment 321, and the distance between the second guide 33 and the arc-shaped segment 321 is the same or equivalent.

It is understood that the extension segment 322 of the first guide 32 and the inner wall of the intake grid 2 at the intake port 11 of the frame 1 form a slide rail or mounting space for mounting the filter 500. The provision of the arc-shaped segment 321 of the first guide 32 and the second guide 33 in combination with the shape and contour of the frame 1 realizes the guiding and mounting of the filter 500, that is, it is advantageous for the arc-shaped segment 321 of the first guide 32 and the second guide 33 to be combined to form the slide rail 34. When the filter 500 is installed, it enters the slide rail or mounting space formed by the extension segment 322 and the inner wall of the intake grid 2 through the slide rail 34 formed by the combination of the arc-shaped segment 321 and the second guide 33. When the filter 500 is removed, the filter 500 comes out of the slide rail or mounting space formed by the extension segment 322 and the inner wall of the intake grid 2 from the slide rail 34 formed by the combination of the arc-shaped segment 321 and the second guide 33.

In another embodiment, the shape, length, structure and contour of the second guide 33 are the same as the shape, length, structure and contour of the first guide 32. Thus, the slide rail 34 formed between the first guide 32 and the second guide 33 is set up to directly attach the filter 500, which makes it possible to effectively avoid wear and tear on the inner wall of the intake grid 2 of the intake port 11 of the frame 1 during the process of attaching the filter 500.

In one embodiment, as shown in Figures 1, 2, 3, 5, 6, 8, 9 and 10, an attachment hook 324 is provided at one end of the extension segment 322 remote from the arc-shaped segment 321, and the extension segment 322 is attached to the frame 1 through the attachment hook 324.

It is understood that the hook 324 is provided at one end of the extension segment 322, and a structure for engaging the hook 324 is provided on the intake grid 2 at the intake port 11 of the frame 1, such as an engagement groove or hole, and the guide rail structure 3 is effectively engaged on the frame 1 by using the engagement of the hook 324 of the extension segment 322 with the engagement groove or hole on the intake grid 2, thereby realizing a detachable connection between the guide rail structure 3 and the frame 1, thereby improving the efficiency and convenience of attachment and detachment. Of course, in other embodiments, a detachable connection method such as a buckle connection, an insertion connection fitting, or a screw connection is adopted between one end of the extension segment 322 and the intake grid 2 and/or the inner wall of the frame 1, and is not limited here.

In one embodiment, as shown in Figs. 1, 5 and 9, in this embodiment, a position limiting groove 323 is provided at one end of the arc-shaped segment 321 far from the extension segment 322, and when the guide rail structure 3 is mounted on the frame 1, the position limiting groove 323 abuts against the frame 1 in a position limiting manner. It can be understood that providing the position limiting groove 323 on the arc-shaped segment 321 is advantageous for realizing the positioning of the guide rail structure 3 and the frame 1, and at the same time, is also advantageous for improving the stability of the guide rail structure 3 mounted on the frame 1.

Furthermore, in order to improve the stability of the guide rail structure 3 mounted on the frame 1, in this embodiment, at least one engaging protrusion is provided at one end of the second guide 33 far from the extension segment 322, and the second guide 33 is engaged with the frame 1 through the engaging protrusion. It is understood that a structure for engaging with the engaging protrusion, such as an engaging groove or an engaging hole, is provided on the inner wall of the intake 11 of the frame 1, and the engagement between the engaging protrusion of the second guide 33 and the engaging groove or the engaging hole on the inner wall of the intake 11 of the frame 1 is utilized to effectively engage the guide rail structure 3 on the frame 1, thereby realizing a detachable connection between the guide rail structure 3 and the frame 1, thereby improving the efficiency and convenience of attachment and detachment.

In one embodiment, as shown in Figures 1, 2, 3, 5, 6, 8, 9 and 10, in this embodiment, a buckle 311 is provided on at least one side of the connection part 31, and the connection part 31 is connected to the frame 1 through the buckle 311.

It is understood that the buckle 311 is provided on the connection part 31, and a structure for fitting the buckle 311, such as a fastening groove or fastening hole, is provided on the inner wall of the intake port 11 of the frame 1 and/or the intake grid 2, and the guide rail structure 3 is effectively engaged on the frame 1 by using the fitting of the buckle 311 on the connection part 31 with the fastening groove or fastening hole on the inner wall of the intake port 11 of the frame 1 and/or the intake grid 2, thereby realizing a detachable connection between the guide rail structure 3 and the frame 1, thereby improving the efficiency and convenience of attachment and detachment. Of course, in other embodiments, a detachable connection method such as a buckle connection, an insertion connection fitting, or a screw connection is adopted between the connection part 31 and the intake grid 2 and/or the inner wall of the frame 1, and is not limited here.

In one embodiment, as shown in Figures 1, 2, 5, 6, 8 and 9, the second guide 33 has a guide portion 331 at one end proximal to the extension segment 322, and the guide portion 331 extends away from the first guide 32.

The guide portion 331 has a curved structure on the second guide device 33, that is, the guide portion 331 is provided in an arc shape, and when the guide rail structure 3 is attached to the air intake 11 of the frame 1, one end of the guide portion 331 far away from the second guide device 33 abuts against the inner wall of the frame 1 or the inner wall of the air intake grid 2. In this way, a slide rail guide surface is effectively formed, and the end of the second guide device 33 is prevented from being pinched in the through hole on the filter 500 when the filter 500 slides along the slide rail 34, making it easy to install and remove the filter 500 smoothly.

In one embodiment, as shown in Figures 1, 5 and 9, in this embodiment, a first position limiting plate 312 is formed in the connection portion 31 to correspond to the arc-shaped segment 321, and the first position limiting plate 312 extends from the arc-shaped segment 321 of the second guide device 33 toward the side facing away from it, and when the guide rail structure 3 is attached to the frame 1, the first position limiting plate 312 abuts against the frame 1 in a position-limited manner.

It can be understood that the provision of the first position limiting plate 312 is advantageous, on the one hand, in that it abuts and fits into the inner wall of the frame 1, thereby blocking and sealing the space on both sides of the first position limiting plate 312, and, on the other hand, is advantageous, on the other hand, in that it abuts and limits the position of the inner wall of the frame 1, thereby improving the mounting stability of the guide rail structure 3.

As shown in Figures 2, 3, 6, 8 and 10, in this embodiment, the connection portion 31 is formed with a first position limiting plate 312 and a second position limiting plate 313 corresponding to the arc-shaped segment 321, the first position limiting plate 312 extends from the first guide 32 of the arc-shaped segment 321 toward the side facing away from it, the second position limiting plate 313 extends from the second guide 33 of the arc-shaped segment 321 toward the side facing away from it, and the first position limiting plate 312 and/or the second position limiting plate 313 are further provided with a position limiting base 314, and when the guide rail structure 3 is attached to the frame 1, the limiting base 314 abuts against the frame 1 while limiting its position.

It is understood that the provision of the first position limiting plate 312 and the second position limiting plate 313 is advantageous for blocking and sealing the space on both sides of the first position limiting plate 312 by abutting and fitting against the inner wall of the frame 1, and is also advantageous for improving the mounting stability of the guide rail structure 3 by abutting and limiting the position against the inner wall of the frame 1, on the one hand. Specifically, as shown in Figures 6, 8, 10 and 11, a baffle 16 is provided so as to protrude from the inner wall of the frame 1, and when the guide rail structure 3 is mounted on the frame 1, the first position limiting plate 312 abuts and fits against the inner wall of the frame 1, and the second position limiting plate 313 abuts and fits against the baffle 16 of the frame 1.

To further position the guide rail structure 3 and improve the mounting stability of the guide rail structure 3, in this embodiment, as shown in Figures 2, 3, 6, 8 and 10, the first position limiting plate 312 and/or the second position limiting plate 313 are further provided with a position limiting base 314, and the inner wall and/or the baffle 16 of the frame 1 are provided with a corresponding position limiting engagement protrusion, and when the guide rail structure 3 is mounted on the frame 1, the position limiting base 314 is engaged with the position limiting engagement protrusion.

In one embodiment, as shown in Figures 1, 2 and 3, the connection portion 31, the first guide device 32 and the second guide device 33 are of an integrally molded structure. It can be understood that forming the connection portion 31 of the guide rail structure 3 into an integrally molded structure with the first guide device 32 and the second guide device 33 effectively improves the processing and production efficiency of the guide rail structure 3, and is also advantageous in improving the strength of the guide rail structure 3.

In one embodiment, as shown in Figures 4, 5, 6, 7, 8, 9, 10, 11, 14 and 16, in this embodiment, the frame 1 further has a filter mounting port 12 that is spaced apart from the air intake 11, and the frame 1 further has a support portion 13 located at the filter mounting port 12, and the end of the support portion 13 close to the air intake 11 is abutted with a positionally restricted one end of the first guide 32 close to the filter mounting port 12.

It is understood that providing the support part 13 at the filter mounting port 12 is advantageous in facilitating support and mounting of the filter 500. When the guide rail structure 3 is attached to the air intake 11 of the frame 1, the end of the support part 13 close to the air intake 11 is abutted with one end of the first guide device 32 close to the filter mounting port 12 in a positionally limited manner, so that the support part 13 and the first guide device 32 provide a continuous and smooth transition, avoiding the occurrence of faults or steps, and improving the convenience and efficiency of mounting the filter 500.

Furthermore, to realize positioning relative to the first guide device 32, as shown in Figures 5 and 9, a position limiting protrusion 131 is provided at the end of the support part 13 close to the intake port 11, and a position limiting groove 323 is provided in the first guide device 32. When the guide rail structure 3 is attached to the intake port 11 of the frame 1, the end of the support part 13 abuts against the end of the first guide device 32, and at this time, the position limiting protrusion 131 is engaged with the position limiting groove 323 to limit the position.

The frame 1 is further provided with a support portion 13 located at the filter mounting port 12, and the end of the support portion 13 close to the intake port 13 is abutted with one end of the first guide 33 close to the filter mounting port 12 with limited positioning.

It can be understood that the provision of the guide segment 14 is advantageous in forming a slideway 15 that guides the installation of the filter 500 in the filter installation port 12, thereby improving the installation efficiency of the filter 500. Specifically, a guide protrusion 141 is provided at the end of the guide segment 14 far from the intake port 11, and the guide protrusion 141 extends in a direction far away from the support portion 13, that is, the guide protrusion 141 and the guide segment 14 are provided in an arc shape, and preferably, the guide protrusion 141 and the guide segment 14 transition in a circular arc. Such an arrangement is advantageous in realizing guidance for the filter 500.

As shown in Figures 14, 15 and 16, the present application further proposes an air conditioner indoor unit 800 including a base 600, a frame assembly 100 connected to the base 600, and a filter 500. For the specific structure of the frame assembly 100, please refer to the above embodiments. The present air conditioner indoor unit 800 adopts all the technical solutions of all the above embodiments, and therefore has at least all the effects brought about by the technical solutions of the above embodiments, and will not be detailed here.

Specifically, the frame assembly 100 is the above-mentioned frame assembly 100, the base 600 is combined with the frame assembly 100 to form an installation chamber, the guide rail structure 3 is located in the installation chamber, and the filter 500 is movably mounted on the slide rail 34 and is located in the air intake 11.

As shown in FIG. 14, a position limiting baffle 510 is provided protruding from one end of the filter 500. The provision of the position limiting baffle 510 is advantageous for an operator to remove the filter 500 from the frame 1 through the position limiting baffle 510 on the filter 500 at the filter mounting port 12, and of course is also advantageous for limiting the contact position between the position limiting baffle 510 and the inner wall of the filter mounting port 12 when attaching the filter 500 to the air intake 11 of the frame 1. This is considered to be understandable.

In the present application, the air conditioner indoor unit 800 may have an automatic filter cleaning function or may clean the filter manually. When the air conditioner indoor unit 800 has an automatic filter cleaning function, the mounting chamber of the air conditioner indoor unit 800 is further provided with a cleaning assembly 700, and in this case, the guide rail structure 3 is not attached to the air intake 11 of the frame 1, and the filter 300 is attached to the air intake 11 of the frame 1, and the cleaning assembly 700 drives the movement of the filter 300 to clean the filter 300. When the air conditioner indoor unit 800 is a device for manually cleaning the filter, the mounting chamber of the air conditioner indoor unit 800 is not provided with a cleaning assembly 700, and in this case, the guide rail structure 3 is attached to the air intake 11 of the frame 1, and the filter 300 can be attached to the air intake 11 of the frame 1 from the slideway 15 of the filter mounting port 12 via the slide rail 34 of the guide rail structure 3. When it is necessary to remove the filter 500, the filter 500 is passed through the position limiting baffle 510 of the filter 500, from the slide railway 15 through the slide rail 34 of the guide rail structure 3, and then removed from the intake port 11 of the frame 1.

The present application further proposes a frame 1. The specific structure of the frame 1 is as shown in Figures 4, 7, 11, 14 and 15, and the frame 1 includes a filter mounting structure. Specifically, the frame 1 has a frame structure or a cover structure, and the frame 1 has an air intake 11 and a filter mounting port 12 that are spaced apart, that is, the upper side of the frame 1 has the air intake 11, and the front side of the frame 1 has the filter mounting port 12. The frame 1 is further provided with an air intake grid 2 at the air intake 11, that is, the air intake grid 2 is integrally molded with the air intake 11 of the frame 1.

Specifically, the filter mounting structure includes a first mounting structure located at the air intake port and a second mounting structure located at the filter mounting port. It is understood that the filter mounting structure is formed by connecting two parts, the first mounting structure and the second mounting structure, i.e., one end of the first mounting structure is removably connected to one end of the second mounting structure, and one end of the first mounting structure is abutted against one end of the second mounting structure to connect them together, forming the filter mounting structure into a whole. In this embodiment, the first mounting structure may be the above-mentioned guide rail structure 3 or a conventional filter mounting structure, and is not limited here.

Furthermore, the filter mounting structure has a mounting space for mounting the filter 500, and the mounting space may be a spatial structure formed by the filter mounting structure itself, or a spatial structure formed by combining the filter mounting structure and the air intake grid 2, and is not limited here. Specifically, the first mounting structure forms a slide rail 34, and the second mounting structure forms a slide way 15, and when one end of the first mounting structure and one end of the second mounting structure are abutted and connected together, the slide rail 34 and the slide way 15 communicate to form a mounting space for mounting the filter 500.

The frame 1 of the present application disassembles the filter mounting structure into two parts, allowing the first part of the mounting structure located at the air intake 11 to be removably connected to the frame 1. This allows the frame 1 to be installed in both air conditioners with an automatic filter cleaning function and air conditioners in which the filter is manually washed, improving the utilization rate of the mold for the frame 1 and production efficiency, simplifying the production process, and reducing production costs. At the same time, the combination of the first part of the mounting structure located at the air intake 11 and the second part of the mounting structure located at the filter mounting port 12 makes it easy to manually remove and wash the filter, improving the convenience of using the frame 1.

As shown in Figures 14, 15 and 16, the present application further proposes an air conditioner indoor unit 800 including a base 600, a frame 1 connected to the base 600, and a filter 500. For the specific structure of the frame 1, please refer to the above examples. Since the present air conditioner indoor unit 800 adopts all the technical solutions of all the above examples, it has at least all the effects brought about by the technical solutions of the above examples, and will not be detailed here. Specifically, the filter 500 is movably attached to the filter mounting structure and is located at the air intake 11.

The present application further proposes an air conditioner including an air conditioner outdoor unit and the above air conditioner indoor unit 800, the air conditioner outdoor unit being connected to the air conditioner indoor unit 800 by a duct. For the specific structure of the air conditioner indoor unit 800, please refer to the above examples.
