[0043] This invention proposes an indoor air conditioner unit, which includes, but is not limited to, round cabinet units, square cabinet units, or other shaped cabinet units. In the following embodiments, a round cabinet unit is mainly used as an example for illustration.

[0044] In embodiments of the present invention, such as FIGS. 1 to 12 As shown, the indoor unit 100 of the air conditioner includes a housing 10 and an air inlet grille 20. The housing 10 has an air inlet (not shown); the air inlet grille 20 includes a fixed grille unit 21 and a movable grille unit 22. The fixed grille unit 21 is fixedly installed at the air inlet, and the movable grille unit 22 is slidably installed at the air inlet. The fixed grille unit 21 and the movable grille unit 22 have a first state and a second state of mutual cooperation. In the first state, the movable grille unit 22 and the fixed grille unit 21 are joined together to cover the air inlet; in the second state, the movable grille unit 22 and the fixed grille unit 21 overlap to create a removal window 101 for removing and installing the filter 30 and / or the purification module.

[0045] Specifically, in this embodiment, the indoor unit 100 is a circular indoor unit. The housing 10 is generally cylindrical, extending vertically. The air inlet is located on the back of the housing 10 and is arc-shaped to fit the housing 10. Correspondingly, the air inlet grille 20 is arc-shaped to fit the air inlet and effectively cover it. A filter 30 is disposed inside the air inlet grille 20 to filter the air entering from the air inlet, thereby ensuring the air quality of the indoor unit 100. In another embodiment, the filter 30 may also have a purification module (such as a PM2.5 removal module, a formaldehyde removal module, or an electro-purification module) inside for deeper air purification.

[0046] It should be noted that, according to the installation mode of the filter screen 30 and the purification module, the role of the dismounting window 101 is also different. For example, in an embodiment, the filter screen 30 is independently arranged on the inner side of the air inlet grille 20, at this time, the dismounting window 101 can be used for dismounting the filter screen 30; in another embodiment, the filter screen 30 is arranged on the air inlet grille 20, and the purification module is independently arranged on the inner side of the filter screen 30, at this time, the dismounting window 101 can be used for dismounting the purification module; in another embodiment, the filter screen 30 is independently arranged on the inner side of the air inlet grille 20, and the purification module is mounted on the filter screen 30, at this time, the dismounting window 101 can be used for dismounting the filter screen 30 and the purification module together. The following embodiments are mainly described by taking the filter screen 30 dismounting from the dismounting window 101 as an example.

[0047] In order to facilitate the installation of the filter screen 30, a filter screen support is arranged on the inner side of the shell 10 corresponding to the air inlet, and the filter screen 30 can be detachably fixed on the filter screen support by buckle connection, magnetic attraction fixing and the like. Of course, the filter screen 30 can also not be fixed on the filter screen support, but simply clamped between the air inlet grille 20 and the filter screen support, and the filter screen support can support the filter screen 30.

[0048] The air inlet grille 20 is divided into a fixed grille unit 21 and a movable grille unit 22. The fixed grille unit 21 can be integrally formed on the shell 10, or can be fixedly mounted on the shell 10 by buckle connection, screw connection and the like, and the movable grille unit 22 is slidably mounted at the air inlet. In this way, when the air conditioner indoor unit 100 is normally used, the movable grille unit 22 and the fixed grille unit 21 are in a first state of being mutually combined to jointly cover the air inlet. When the filter screen 30 needs to be cleaned, the movable grille unit 22 is only needed to be slid to a second state of being mutually overlapped with the fixed grille unit 21, so that the filter screen 30 can be taken out from the dismounting window 101 for cleaning. After cleaning, the filter screen 30 can be inserted from the dismounting window 101, which is simple and convenient to operate and saves time and effort. The movable grille unit 22 can be slid open in the left-right direction or in the up-down direction, which is not specifically limited here.

[0049] It should be noted that the movable grille unit 22 and the fixed grille unit 21 are mutually overlapped here, which can be partially overlapped or completely overlapped, as long as a dismounting window 101 sufficient for dismounting the filter screen 30 is left, which is not specifically limited here. At the same time, the movable grille unit 22 can be slid to the inner side of the fixed grille unit 21 to overlap, or can be slid to the outer side of the fixed grille unit 21 to overlap. Of course, in actual application, in order to improve the overall appearance of the air conditioner indoor unit 100, the movable grille unit 22 is preferably slid to the inner side of the fixed grille unit 21 to overlap.

[0050] It can be understood that, compared with the technical solution that the air inlet grille is integrally formed on the shell or fixed on the shell through the buckle connection in the traditional air conditioner indoor unit, the air inlet grille 20 of the air conditioner indoor unit 100 does not need to be disassembled as a whole, and only needs to be slid to the second state of overlapping with the fixed grille unit 21 to form the disassembly window 101 for disassembling the filter screen 30 and / or the purification module, thereby greatly improving the disassembly and washing convenience of the filter screen 30 and / or the purification module. Moreover, the dynamic grille unit 22 is opened in a sliding manner, which effectively solves the technical problem that the traditional air inlet grille 20 is connected to the back of the shell 10 through the buckle, and the visibility of the buckle is poor and the disassembly is inconvenient, so that the installation position of the air conditioner indoor unit 100 is not limited, and the air conditioner indoor unit 100 can be installed against the wall or against the corner, thereby effectively improving the application range of the air conditioner indoor unit 100.

[0051] The technical solution of the present application divides the air inlet grille 20 into the fixed grille unit 21 and the dynamic grille unit 22, wherein the dynamic grille unit 22 is slidably installed at the air inlet, so that when the filter screen 30 and / or the purification module needs to be cleaned, the air inlet grille 20 does not need to be disassembled as a whole, and only needs to be slid to the second state of overlapping with the fixed grille unit 21 to form the disassembly window 101, so that the filter screen 30 and / or the purification module can be taken out from the disassembly window 101 for cleaning, which is simple and convenient, saves time and effort, thereby effectively improving the disassembly and washing convenience of the filter screen 30 and / or the purification module, and is beneficial to timely cleaning of the filter screen 30 and / or the purification module by the user.

[0052] Further, the shell 10 includes a back plate 11 and an air inlet frame 12, the air inlet is formed on the back plate 11, the air inlet frame 12 is arranged at the periphery of the air inlet and protrudes outwardly from the back plate 11, the fixed grille unit 21 is fixedly connected to the air inlet frame 12, and the dynamic grille unit 22 is slidably connected to the air inlet frame 12.

[0053] Specifically, in the embodiment, the shell 10 includes a face plate, a back plate 11 and an air inlet frame 12, wherein the air inlet is formed on the back plate 11, the face plate is provided with an air outlet, and a space for installing a heat exchanger and a fan assembly is formed between the face plate and the back plate 11. The air inlet frame 12 is arranged at the air inlet and protrudes outwardly from the back plate 11. It can be understood that the back plate 11 is usually thin-walled and is not convenient for installing the air inlet grille 20, and if the air inlet grille 20 is arranged on the inner side of the back plate 11, the installation space of the heat exchanger and the fan assembly will be occupied, thereby affecting the heat exchange performance of the air conditioner indoor unit 100. Therefore, by arranging the air inlet frame 12, the assembly of the air inlet grille 20 is more stable and reliable, and arranging the air inlet grille 20 on the outer side of the back plate 11 does not need to occupy the installation space on the inner side of the back plate 11.

[0054] Further, please refer to FIGS. 2 to 9, the movable grid unit 22 and the fixed grid unit 21 are arranged adjacent to each other in the left-right direction, and the movable grid unit 22 is slidably fitted with the air inlet frame 12 in the left-right direction. Specifically, in the embodiment, when in the first state (as shown in FIG. 3 , the movable grid unit 22 and the fixed grid unit 21 are fit together in the left-right direction to jointly cover the air inlet, and when in the second state (as shown in FIG. 4 , the movable grid unit 22 slides in the left-right direction to the side close to the fixed grid unit 21 to leave the dismounting window 101, so that the filter screen 30 can be conveniently dismounted and mounted.

[0055] It can be understood that the dismounting manner of the air inlet grid 20 is not limited to being dismounted into only two pieces in the left-right direction. For example, as shown in FIG. 2 , the air inlet grid 20 can be dismounted into four pieces. Specifically, the air inlet grid 20 includes a left upper fixed grid unit 21, a right upper movable grid unit 22, a left lower fixed grid unit 21, and a right lower movable grid unit 22. The left upper fixed grid unit 21 and the right upper movable grid unit 22 are fit together in the left-right direction, and the left lower fixed grid unit 21 and the right lower movable grid unit 22 are fit together in the left-right direction, so as to effectively improve the opening flexibility of the movable grid unit 22. Of course, there are many dismounting manners of the air inlet grid 20, and the specific dismounting manner can be set according to the shape and size of the air inlet, which is not limited here.

[0056] Further, referring to FIGS. 3 to 5 , the air inlet frame 12 includes two horizontal frame strips opposite in the up-down direction, and the side of any horizontal frame strip opposite to the other horizontal frame strip is provided with a horizontal sliding groove 121 slidably fitted with the movable grid unit 22;

[0057] The horizontal sliding groove 121 includes a first sliding section, a second sliding section, and a bending section connecting the first sliding section and the second sliding section. The first sliding section is arranged side by side with the fixed grid unit 21 in the left-right direction, and the second sliding section is located inside the fixed grid unit 21.

[0058] In the embodiment, the horizontal sliding groove 121 is arranged in a Z shape. Specifically, the first sliding section is arranged side by side with the fixed grid unit 21 in the left-right direction. Thus, when in the first state, the movable grid unit 22 is arranged in the first sliding section, so that the appearance surface of the movable grid unit 22 and the appearance surface of the fixed grid unit 21 can be on the same outer surface, so that the whole air conditioner indoor unit 100 is more beautiful. When the filter screen 30 needs to be dismounted and mounted, the movable grid unit 22 is slid to the second sliding section through the bending section, so that the movable grid unit 22 is accommodated inside the fixed grid unit 21, thereby facilitating the dismounting and mounting of the filter screen 30.

[0059] Specifically, in the present embodiment, in order to adapt to the air inlet of the circular cabinet machine, the air inlet grille 20 is arranged in the form of an arc-shaped plate to adapt to the air inlet, and correspondingly, the fixed grille unit 21 and the movable grille unit 22 are also arranged in the form of arc-shaped plates. The first sliding section and the second sliding section are both arranged in the form of arc-shaped grooves to adapt to the arc-shaped air inlet grille 20.

[0060] Further, the upper and lower two side edges of the movable grille unit 22 are respectively provided with first sliding shafts 221, and the movable grille unit 22 is slidably connected to the corresponding transverse sliding groove 121 through the first sliding shafts 221. In the present embodiment, the first sliding shafts 221 and the transverse sliding groove 121 are slidably connected to make the sliding of the movable grille unit 22 more smooth. Specifically, the upper and lower two side edges of the movable grille unit 22 are each provided with two first sliding shafts 221. It can be understood that, in the process of sliding into the inside of the fixed grille unit 21, the movable grille unit 22 can rotate around the first sliding shafts 221, so that the movable grille unit 22 can smoothly pass through the inflection point of the bending section, thereby avoiding scratching the outer surface of the fixed grille unit 21.

[0061] Due to the long-term operation of the air conditioner indoor unit 100, the dust accumulated on the air inlet grille 20 is also relatively serious, and therefore, the air inlet grille 20 also needs to be regularly disassembled and cleaned. In order to facilitate the disassembly and assembly of the air inlet grille 20, on the basis of the above embodiment, further, a gap H1 is formed between the top of the first sliding shaft 221 on the upper side and the groove bottom of the corresponding transverse sliding groove 121, and the first sliding shaft 221 on the lower side is inserted into the corresponding transverse sliding groove 121 by a depth of H2, wherein H1 is greater than or equal to H2.

[0062] In the present embodiment, specifically, as shown in FIG. 7 the natural state (i.e., when the movable grille unit 22 is normally assembled on the air inlet), a gap H1 is formed between the top of the first sliding shaft 221 on the upper side and the groove bottom of the transverse sliding groove 121. In this way, when the movable grille unit 22 in the transverse sliding groove 121 is disassembled, the movable grille unit 22 is first lifted upward, and since H1 is greater than or equal to H2, the movable grille unit 22 has sufficient upward movement space, so that the first sliding shaft 221 at the bottom of the movable grille unit 22 can be separated from the lower transverse sliding groove 121, thereby enabling the movable grille unit 22 to be smoothly taken out from the transverse sliding groove 121.

[0063] Further, the connection between the first sliding section and the bending section is provided with an elastic compression portion 122, which is compressed on the back surface of the movable grille unit 22 in the first state, so that the appearance surface of the movable grille unit 22 is flush with the appearance surface of the fixed grille unit 21.

[0064] Specifically, in the present embodiment, the elastic pressing portion 122 is arranged on the groove wall surface of the bending section away from the fixed grille unit 21, and can be elastically deformed along the air inlet direction. When in the first state, the movable grille unit 22 is arranged in the first sliding section, and the elastic pressing portion 122 is pressed against the back surface of the movable grille unit 22, so that the appearance surface of the movable grille unit 22 is flush with the appearance surface of the fixed grille unit 21 (the appearance surfaces of the movable grille unit 22 and the fixed grille unit 21 are substantially on the same curved surface), thereby making the overall appearance of the air conditioner indoor unit 100 more beautiful. When it is required to switch to the second state, the movable grille unit 22 is pressed against the elastic pressing portion 122 during sliding, so that the elastic pressing portion 122 can be elastically deformed inward to make way, thereby enabling the movable grille unit 22 to smoothly slide through the bending section and into the second sliding section.

[0065] Further, please refer to FIGS. 10 to 12 In another embodiment, the movable grille unit 22 and the fixed grille unit 21 are arranged adjacent in the up-down direction, and the movable grille unit 22 and the air inlet frame 12 are slidably connected in the up-down direction. Specifically, in the present embodiment, when in the first state, the movable grille unit 22 and the fixed grille unit 21 are combined with each other in the up-down direction to jointly cover the air inlet, and when in the second state, the movable grille unit 22 slides in the up-down direction towards the side close to the fixed grille unit 21 to make way for the dismounting window 101, thereby facilitating the dismounting of the filter screen 30. It can be understood that the dismounting manner of the air inlet grille 20 is not limited to being dismounted into two pieces in the up-down direction. For example, as shown in FIG. 10 , the air inlet grille 20 can be dismounted into four pieces, further effectively improving the opening flexibility of the movable grille unit 22.

[0066] Further, the air inlet frame 12 includes two vertical frame strips opposite in the left-right direction, and the side of any vertical frame strip facing the other vertical frame strip is provided with a vertical sliding groove 123 slidably connected with the movable grille unit 22, the vertical sliding groove 123 includes a first sliding section, a second sliding section, and a bending section connecting the first sliding section and the second sliding section, the first sliding section is arranged side by side with the fixed grille unit 21 in the up-down direction, and the second sliding section is located on the inner side of the fixed grille unit 21.

[0067] In the present embodiment, the vertical sliding groove 123 is generally Z-shaped, wherein the first sliding section is arranged side by side with the fixed grille unit 21 in the up-down direction, so that when in the first state, the movable grille unit 22 is arranged in the first sliding section, so that the appearance surface of the movable grille unit 22 and the appearance surface of the fixed grille unit 21 can be on the same outer surface, thereby making the overall appearance of the air conditioner indoor unit 100 more beautiful. When it is required to dismount and clean the filter screen 30, the movable grille unit 22 is slid through the bending section into the second sliding section, so that the movable grille unit 22 can be accommodated on the inner side of the fixed grille unit 21, thereby facilitating the dismounting of the filter screen 30.

[0068] Further, the left and right sides of the movable grille unit 22 are respectively provided with second sliding shafts 222, and the movable grille unit 22 is in sliding cooperation with the corresponding vertical sliding grooves 123 through the second sliding shafts 222. In this embodiment, specifically, the left and right sides of the movable grille unit 22 are respectively provided with two second sliding shafts 222, and the movable grille unit 22 is in sliding cooperation with the vertical sliding grooves 123 through the second sliding shafts 222, so that the sliding of the movable grille unit 22 is more smooth.

[0069] Further, the movable grille unit 22 and the shell 10 are provided with a clamping structure 13, and the movable grille unit 22 is clamped and fixed with the shell 10 through the clamping structure 13 in the first state. In this embodiment, the clamping structure 13 is arranged to enable the movable grille unit 22 to be clamped and fixed with the shell 10 in the first state, thereby ensuring the normal operation of the air conditioner indoor unit 100.

[0070] The specific form of the clamping structure 13 is various, and specifically, in an embodiment, please refer to FIG. 2 and FIG. 9 When the movable grille unit 22 and the shell 10 are in sliding cooperation in the left-right direction, the clamping structure 13 includes a clamping groove arranged on the movable grille unit 22 and a clamping buckle arranged on the shell 10, so that the movable grille unit 22 can be locked on the shell 10 through the cooperation of the clamping buckle and the clamping groove.

[0071] In another embodiment, please refer to FIG. 10 , the movable grille unit 22 and the fixed grille unit 21 are in sliding cooperation in the up-down direction, and the fixed grille unit 21 is arranged at the lower part of the air inlet, and the clamping structure 13 is an elastic clamping buckle arranged at the upper part of the shell 10. When the movable grille unit 22 slides to the upper part of the air inlet, the elastic clamping buckle is clamped and cooperated with the movable grille unit 22, so that the movable grille unit 22 can be locked to avoid the movable grille unit 22 from sliding downward.
