[0035] Conventional air conditioner filters are usually removed by opening the control panel; however, opening the control panel is too complicated, making some people hesitant to do so, which makes cleaning the filter troublesome. Considering this, some air conditioners now place the filter on the top of the unit. As a result, the airflow area of ​​the filter is smaller, the filtration effect is poor, and dust easily accumulates on the filter, causing it to become dirty and clogged.

[0036] This utility model discloses a housing 10 for an indoor unit of an air conditioner. Please refer to [link / reference needed]. Figures 1 to 4 In one embodiment of the present invention, the housing includes a main body 11 and a filter mounting part 30. The filter mounting part 30 is disposed inside the main body 11 and located at the top of the main body 11. The filter mounting part 30 is used to cooperate with the filter 20 for installation. The filter mounting part 30 extends at least partially in the vertical direction.

[0037] It should be emphasized that the specific implementation of the housing is not limited. It can be the entire outer shell of the air conditioner indoor unit 100, or it can be just the middle frame of the air conditioner indoor unit 100, etc. There is no limitation here. The specific implementation of the filter installation part 30 is not limited. It can be in the form of guide ribs. For example, guide ribs are provided on the main body 11 at the return air vent 14, and guide grooves are opened on the filter 20. The filter 20 is limited and installed by the cooperation of the guide grooves and guide ribs. Of course, it can also be in the form of sliding grooves. Correspondingly, sliding ribs are provided on the filter 20, so that the filter 20 can be slidably installed by the sliding grooves. In addition, it can also be in the form of multiple magnetic parts. For example, multiple magnetic parts are provided on the main body 11, and the multiple magnetic parts are at least partially spaced along the vertical direction, etc. There is no limitation here.

[0038] The filter installation part 30 extends at least partially in the vertical direction. It may be that the first section of the filter installation part 30 extends in the vertical direction, or the tail section 31 of the filter installation part extends in the vertical direction, or the entire filter installation part 30 extends in the vertical direction, etc. There is no limitation here. Specifically, it may extend upward, or downward, or a part may extend upward and a part may extend downward, etc. There is no limitation here.

[0039] In this embodiment, the filter mounting portion 30 extends at least partially in the vertical direction. This allows the filter 20 to be constrained by the filter mounting portion 30 when installed, extending at least partially in the vertical direction. Compared to current top-mounted filters, the filter 20 has a larger airflow area due to its vertical extension. Furthermore, when dust falls onto the filter 20, it slides down under its own gravity, preventing dust accumulation and clogging, thus improving the filtration efficiency of the filter 20.

[0040] In a further embodiment, the tail section 31 of the filter mounting part extends downward. In the technical solution of this embodiment, by setting the tail section 31 of the filter mounting part to extend downward, when the filter 20 is installed on the filter mounting part 30, the portion of the filter 20 located on the tail section 31 of the filter mounting part will also extend downward. At this time, compared with the flat-lay filter, the filter 20 can be made larger and the air passage area will also become larger because it extends downward, thus improving the filtration effect of the filter 20.

[0041] Furthermore, since its tail section extends downwards, when the filter installation part 30 is a sliding rib or a sliding groove, the end section of the filter 20 can move along the downward-extending tail section toward the interior of the air conditioner housing, allowing part of the filter 20 to enter the installation cavity 41 of the heat exchanger inside the air conditioner, further increasing the air passage area of ​​the filter 20.

[0042] In a further embodiment, the main body 11 has a top wall 12 and a first partition wall 13 arranged opposite each other in the vertical direction. The top wall 12 is provided with a return air vent 14. The first partition wall 13 is arranged close to the top wall 12 to define a sliding groove together with the first partition wall 13. The filter installation part 30 includes the sliding groove, the sliding groove and the return air vent 14 are connected, and the tail section of the sliding groove extends downward.

[0043] In the technical solution of this embodiment, by setting the filter installation part 30 as a sliding groove, and the sliding groove is composed of the top wall 12 and the first partition wall 13, in actual use, the top wall 12 and the first partition wall 13 can jointly clamp the filter 20. Compared with the solution of opening the sliding groove on the filter 20, since the sliding groove is opened on the main body 11, the width of the sliding groove can be opened to be larger, which provides better stability for the installation of the filter 20. Furthermore, the filter 20 is installed in the sliding groove, which can filter the airflow passing through the return air vent 14. Correspondingly, at this time, the filter 20 can filter the return air at the return air vent 14.

[0044] It should be noted that the downward extension of the tail section of the chute can be a direct downward extension, an inclined downward extension, etc., and is not limited here.

[0045] It should be emphasized that the main body 11 can be a mounting frame installed on the top of the air conditioner indoor unit 100, or it can be directly formed by the middle frame of the air conditioner indoor unit 100, and there is no limitation here.

[0046] In some embodiments, the main body 11 includes a middle frame, and the housing further includes a base 40. The middle frame and the base 40 define a mounting cavity 41 for mounting an indoor heat exchanger 50, and the first partition wall 13 constitutes at least a portion of the top wall 12 of the mounting cavity 41; the tail section of the slide extends downward through the first partition wall 13 to communicate with the mounting cavity 41.

[0047] In this embodiment, since the tail section of the slide groove penetrates downward through the first partition wall 13 and is connected to the mounting cavity 41, after the filter screen 20 is installed in the slide groove, the filter screen 20 is pushed further into the slide groove. The end section of the filter screen 20 can move downward along the tail section of the slide groove, extend out from the tail section of the slide groove, and enter the mounting cavity 41. Correspondingly, at this time, part of the filter screen 20 is installed on the top of the main body 11, and another part is located in the mounting cavity 41. Compared with the scheme where the filter screen 20 is only set on the top of the air-conditioned room, the filter screen 20 is also located in the mounting cavity 41, which increases the air passage area of ​​the filter screen 20. Moreover, the part of the filter screen 20 located in the mounting cavity 41 is less prone to dirt clogging than the part located on the top, due to the shielding effect of the base 40, which further improves the filtration effect of the filter screen 20.

[0048] Specifically, the configuration of the tail section of the chute is not limited. It can be formed by both the first partition wall 13 and the top wall 12 bending downwards, or it can be formed by only the top wall 12 bending downwards and being spaced apart from the first partition wall 13. The gap between the downward-bent part of the top wall 12 and the first partition wall 13 constitutes the tail section of the chute, etc., which are not limited here.

[0049] In one embodiment, the top wall 12 bends downward to define the tail section of the slide. With this configuration, during the installation of the filter screen 20, the installer pushes the filter screen 20 into the slide from the first end. After the filter screen 20 has moved for a period of time, the end of the filter screen 20 will come into contact with the downwardly bent portion of the top wall 12 and move downward along the extension direction of the top wall 12, thereby guiding the end of the filter screen 20 into the mounting cavity 41.

[0050] It is understandable that when the filter 20 extends into the mounting cavity 41, it is prone to interference with the components inside the mounting cavity 41, such as interference with the indoor heat exchanger 50, the fan, etc. Therefore, in order to avoid interference between the filter 20 and the components inside the mounting cavity 41, in a further embodiment, a limiting rib 42 is connected to the base 40. The limiting rib 42 is located inside the mounting cavity 41 and is set at an angle to the base 40 to define a receiving channel with one end open between it and the base 40. The open end of the receiving channel is set corresponding to the through-hole of the tail section of the slide groove. The receiving channel is used to accommodate the tail section of the filter 20.

[0051] In the technical solution of this embodiment, by setting the limiting rib 42, when the filter screen 20 extends into the mounting cavity 41, the limiting rib 42 can limit the filter screen 20, thereby preventing the filter screen 20 from moving toward the indoor heat exchanger 50 and interfering with the indoor heat exchanger 50.

[0052] It should be noted that the angle between the limiting rib 42 and the base 40 is not limited and can be 10°, 20°, 30°, etc. It can be understood that the larger the angle between the limiting rib 42 and the base 40, the closer it is to 90°, the closer the limiting rib 42 will be to the indoor heat exchanger 50. At this time, it is easy to interfere with the indoor heat exchange. Therefore, in a further embodiment, the angle between the limiting rib 42 and the base 40 is between 5° and 60°. The angle is greater than 5° to ensure that the receiving channel is large enough to accommodate the end section of the filter screen 20. The angle between the limiting rib 42 and the base 40 is less than or equal to 60° to avoid the limiting rib 42 occupying too much space in the mounting cavity 41 and interfering with other components.

[0053] To prevent the filter screen 20 from moving vertically after installation, a limiting groove 43 is formed in the portion of the base 40 located in the receiving channel. The limiting groove 43 is used to limit the end of the filter screen 20. In this embodiment, when the user installs the filter screen 20, the filter screen 20 is inserted from the first section of the filter screen mounting part 30. The filter screen 20 moves along the extension direction of the filter screen mounting part 30, extends out from the through-hole of the tail section of the slide, and enters the mounting cavity 41. The end of the filter screen 20 continues to move downward until it moves into the limiting groove 43. At this time, the limiting groove 43 can limit the end of the filter screen 20 in the vertical direction, preventing the filter screen 20 from moving vertically. It should be noted that the formation position of the limiting groove 43 is not limited. It can be at the bottom of the receiving channel, or in the lower middle part of the receiving channel, etc., and is not limited here.

[0054] The method of forming the limiting groove 43 is not limited. It can be formed by directly recessing part of the base 40, or by setting multiple limiting ribs on the base 40, with the interval between the multiple limiting ribs forming the limiting groove 43, etc., which are not limited here.

[0055] It should be emphasized that after the filter screen 20 is installed, the end of the filter screen 20 abuts against the limiting groove 43. With this setting, even if dust falls, it will accumulate in the limiting groove 43 and will not enter the installation area of ​​the indoor heat exchanger 50.

[0056] Meanwhile, to facilitate the installation and removal of the filter 20 by the installer, the first section 33 of the slide groove extends upward through the top wall 12. The filter 20 is inserted into or removed from the slide groove through the first section 33. With this configuration, since the first section 33 of the slide groove extends upward through the top wall 12, the installation port of the first section 33 of the slide groove can be exposed on the top wall 12. The installer can directly operate on the filter 20 from the top of the indoor unit 100 of the air conditioner to install and remove the filter 20, thus improving the ease of installation and removal of the filter 20.

[0057] The filter mounting portion 30 may extend at least partially in the vertical direction, or the guide segment 32 may extend at least partially in the vertical direction. Specifically, in another embodiment, the filter mounting portion 30 includes a guide segment 32 that connects to its first segment, and the guide segment 32 extends at least partially in the vertical direction.

[0058] Specifically, in this embodiment, the tail section 31 of the filter mounting part in the above embodiment can be provided separately. Correspondingly, in this case, the tail section 31 of the filter mounting part is connected to the guide section 32. Alternatively, the filter mounting part 30 may only include the head section and the guide section 32, which is not limited here. The head section of the filter mounting part 30 refers to the extension section used for inserting or removing the filter 20.

[0059] In the technical solution of this embodiment, by extending at least part of the guide section 32 in the vertical direction, when the filter screen 20 is installed in the guide section 32, the filter screen 20 will also extend at least part of the vertical direction under the limitation of the guide section 32. Compared with the current flat filter screen 20, since the filter screen 20 extends at least part of the vertical direction, its air passage area will be larger. Furthermore, when dust falls on the filter screen 20, since the filter screen 20 extends at least part of the vertical direction, the dust will slide down under its own gravity, thereby making the filter screen 20 less prone to dust accumulation and clogging, thus improving the filtration effect of the filter screen 20.

[0060] Specifically, the specific implementation of the guide segment 32 extending in the vertical direction is not limited. It can be a component extending downward, or it can gradually extend upward, or it can bend back and forth in the vertical direction, etc., and is not limited here.

[0061] In one embodiment, the guide section 32 extends gradually upward from the first segment to the last segment of the filter installation part 30. This arrangement ensures that the portion of the filter 20 located on the guide section 32 also extends gradually upward after installation. When dust falls onto the filter 20, it slides downward, guiding the dust to the side of the housing 10 of the indoor air conditioner unit with the panel, i.e., the front side, making it convenient for the user to clean the dust. Furthermore, the gradual upward extension of the filter 20 prevents any indentations, avoiding dust accumulation and preventing the filter 20 from becoming clogged.

[0062] In an embodiment where the filter mounting section 30 also includes a tail section 31, since the guide section 32 extends gradually upwards, the tail section 31 of the filter mounting section connects to the guide section 32. That is, the connection point between the tail section 31 of the filter mounting section and the guide section 32 is located at the highest point of the guide section 32. Correspondingly, this can prevent dust on the guide section 32 from sliding down to the tail section 31 of the filter mounting section and entering the mounting cavity 41, thereby improving the dustproof effect on the indoor unit 100 of the air conditioner.

[0063] In another embodiment, the guide segment 32 is extended in a curve. Compared with straight or oblique lines, the curve has a longer segment length, which allows the filter screen 20 to have a larger air passage area, thereby effectively improving the filtration effect of the filter screen 20.

[0064] It is understood that the guide segment 32 can be arranged to extend gradually upwards or to extend in a curve. These two technical solutions can be chosen to be used, or both can be used. No limitation is made here.

[0065] In a further embodiment, the guide segment 32 is arranged in an arc shape. The arc shape has better smoothness, which allows the filter screen 20 to move more smoothly during the assembly and disassembly process, thus improving the stability of the filter screen 20 during the assembly and disassembly process.

[0066] In other embodiments, the guide section 32 may also be arched, so that dust falling onto the filter screen 20 can slide off from both sides of the arch, making the filter screen 20 less prone to clogging.

[0067] This utility model also proposes an air conditioner indoor unit 100, which includes a filter 20 and a housing 10. The filter 20 is installed in the filter mounting part 30 of the housing 10. The specific structure of the housing 10 is as described in the above embodiments. Since this air conditioner indoor unit 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The above provides a detailed description of the housing and indoor unit of the air conditioner provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
