[0053] Refer to Figure 1 、 Figure 2 and Figure 3 According to an embodiment of the present invention, the air conditioner indoor unit 100 includes: a housing 1, an indoor heat exchanger and a driving fan are provided inside the housing 1, and the housing 1 is further provided with an air inlet 11 and an air outlet 12. When the driving fan operates, it can drive the air outside the housing 1 to enter the housing 1 through the air inlet 11 and exchange heat with the indoor heat exchanger, and the air that has exchanged heat with the indoor heat exchanger is discharged into the room through the air outlet 12, thereby achieving the effect of adjusting the indoor temperature.

[0054] Refer to Figure 3 、 Figure 4 and Figure 5 According to an embodiment of the present invention, the air conditioner indoor unit 100 further includes: a filter net 2 and a cleaning module 3. The filter net 2 is arranged on the housing 1 to filter the air flowing in through the air inlet 11, improve the air quality in the room, and the cleaning module 3 is arranged on the housing 1 and is used to clean the filter net 2.

[0055] In an embodiment of the present invention, the filter screen 2 is movably disposed in the housing 1. When the filter screen 2 needs to be cleaned, the filter screen 2 moves towards the cleaning module 3 so that the cleaning module 3 can clean the filter screen 2.

[0056] Referring to Figure 6 and Figure 7 , the cleaning module 3 includes a cleaning component 32 and a cleaning housing 31. The cleaning housing 31 is disposed in the housing 1, and the cleaning component 32 is disposed in the cleaning housing 31. The cleaning component 32 is used to clean the filter screen 2 that moves into the cleaning housing 31, so that the dirt on the filter screen 2 can be collected in the cleaning housing 31, preventing the dirt from spreading in the housing 1 and avoiding the situation that the internal structure of the housing 1 is contaminated. And in an embodiment of the present invention, the cleaning housing 31 is detachably disposed in the housing 1. After the cleaning module 3 completes the cleaning work on the filter screen 2, the user can detach the cleaning housing 31 and pour out the dirt in the cleaning housing 31.

[0057] For the air conditioner indoor unit 100 according to an embodiment of the present invention, the filter screen 2 can move to the cleaning module 3 for cleaning, eliminating the need for the user to manually clean the filter screen 2, improving the convenience of using the air conditioner indoor unit 100; when cleaning the filter screen 2, the dirt on the filter screen 2 is collected in the cleaning housing 31, avoiding the spread of dirt in the housing 1; the cleaning housing 31 can be detached, facilitating the user to handle the dirt in the cleaning housing 31. The method of handling the dirt in the cleaning housing 31 is simple, without the need to additionally provide a dedicated structure for handling the dirt in the cleaning housing 31 inside the air conditioner indoor unit 100, reducing the cost of the air conditioner indoor unit 100.

[0058] It should be noted that the cleaning housing 31 is a part of the cleaning module 3. The cleaning module 3 further includes a cleaning component 32. The cleaning housing 31 is detachably disposed in the housing 1. The cleaning component 32 can be fixedly disposed in the housing 1, or the cleaning component 32 can also be detachably disposed in the housing 1.

[0059] For example, in some embodiments, the cleaning component 32 is fixed to the housing 1, and the cleaning housing 31 is detachably disposed in the housing 1. When the cleaning housing 31 is installed on the housing 1, the cleaning component 32 is located inside the cleaning housing 31. In an embodiment of the present invention, when the user cleans the dirt in the cleaning housing 31, only the cleaning housing 31 needs to be detached, and the structure to be detached is lighter, making the operation more convenient and fast.

[0060] Referring to Figure 6 and Figure 7, in some other embodiments, the cleaning component 32 is fixedly arranged inside the cleaning housing 31, and the cleaning housing 31 is detachably arranged on the housing 1, that is, the cleaning module 3 is integrally detachably arranged on the housing 1. In the embodiments of the present invention, the cleaning module 3 as a whole can be detached, which is beneficial to the maintenance or replacement of the cleaning module 3 and reduces the maintenance cost of the air conditioner indoor unit 100.

[0061] Referring to Figure 1 、 Figure 2 and Figure 3 , in some embodiments, the housing 1 includes a front frame 13, the front frame 13 is provided with a receiving cavity, the receiving cavity is provided with a first opening 131, and the cleaning housing 31 is detachably arranged in the receiving cavity through the first opening 131.

[0062] When the user needs to clean the cleaning housing 31, after detaching the cleaning housing 31 from the housing 1, the cleaning housing 31 is taken out of the receiving cavity through the first opening 131; when the user finishes cleaning the cleaning housing 31, the cleaning housing 31 is stuffed into the receiving cavity through the first opening 131 and installed on the housing 1.

[0063] In the above technical solution, by providing the first opening 131 specifically for installing and detaching the cleaning housing 31, when the user performs the operation of installing and detaching the cleaning housing 31, there is no need to disassemble the housing 1, which improves the convenience of using the air conditioner indoor unit 100.

[0064] The first opening 131 in the embodiments of the present invention can be arranged on the front side of the front frame 13, or can be arranged on the left side, right side, lower side, etc. of the front frame 13, as long as it is convenient for the user to install and detach the cleaning housing 31.

[0065] Referring to Figure 1 、 Figure 2 and Figure 3 , in some further embodiments, the first opening 131 can be opened or closed. When it is necessary to install or detach the cleaning housing 31, the first opening 131 is opened, and when there is no need to process the cleaning housing 31, the first opening 131 is closed to prevent external substances such as dust and insects from entering the receiving cavity and affecting the operation of the air conditioner indoor unit 100.

[0066] The first opening 131 in the embodiments of the present invention is designed to be closable. When there is no need to process the cleaning housing 31, the first opening 131 is in a closed state, which not only avoids the risk of external substances affecting the operation of the internal structure of the air conditioner indoor unit 100, but also improves the aesthetics of the air conditioner indoor unit 100.

[0067] Referring to Figure 1 、 Figure 2 and Figure 3, in some embodiments, the housing 1 further includes a panel 14, which is rotatably arranged outside the front frame 13 to expose or block the front frame 13. When there is a problem with the air conditioner indoor unit 100, the panel 14 can be rotated to open and expose the front frame 13, facilitating the user to view and repair the internal structure of the air conditioner indoor unit 100.

[0068] Referring to Figure 1 , Figure 2 and Figure 3 , in some specific embodiments, the first opening 131 is arranged on the front side of the front frame 13, and the panel 14 is rotatably arranged on the front frame 13 to open or close the first opening 131.

[0069] In the embodiments of the present invention, by arranging the first opening 131 on the front side of the front frame 13, the panel 14 can also function to open or close the first opening 131, eliminating the need to provide other structures for opening or closing the first opening 131, and achieving the simplification of the structure of the air conditioner indoor unit 100.

[0070] Referring to Figure 3 , Figure 4 and Figure 5 , in some embodiments, the housing 1 includes a mounting bracket 4, the filter net 2 is movably arranged on the mounting bracket 4, and the cleaning housing 31 is detachably arranged on the mounting bracket 4.

[0071] In the above technical solution, the filter net 2 is movably arranged on the mounting bracket 4, which defines the movement mode of the filter net 2 and improves the stability of the filter net 2. The cleaning housing 31 is detachably arranged on the mounting bracket 4, shortening the distance between the cleaning module 3 and the filter net 2, and facilitating the filter net 2 to move to the cleaning module 3 through the mounting bracket 4 for cleaning.

[0072] Referring to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the mounting bracket 4 includes a frame part 41 and a skeleton 42. The frame part 41 extends in the horizontal direction and is arranged opposite to the air inlet 11. The filter net 2 is arranged on the frame part 41 so that the filter net 2 can filter the air entering through the air inlet 11. The frame part 41 also defines a moving space for the filter net 2, enabling the filter net 2 to move only along the extending direction of the moving space, thereby improving the stability of the movement of the filter net 2.

[0073] The skeleton 42 is installed at one end of the frame part 41, and the cleaning housing 31 is detachably arranged on the skeleton 42. That is to say, the cleaning housing 31 is arranged at one end of the frame part 41, avoiding the influence of the cleaning module 3 on the air intake of the air conditioner indoor unit 100.

[0074] The framework 42 connects the moving space and the internal space of the cleaning housing 31 so that the filter net 2 can move into the cleaning housing 31. When the filter net 2 needs to be cleaned, the filter net 2 moves along the moving space to the framework 42 and then enters the internal space of the cleaning housing 31 through the framework 42, so that the cleaning component 32 in the cleaning housing 31 can clean the filter net 2.

[0075] Referring to Figure 4 、 Figure 6 and Figure 7 , in some embodiments, the frame part is provided with a first moving space 414 and a second moving space 415, a guiding component 33 is arranged in the cleaning housing 31, the guiding component 33 is provided with a transition space 331, and the first moving space 414 is communicated with the second moving space 415 through the transition space 331, so that the filter net 2 in the first moving space 414 moves into the second moving space 415 through the transition space 331.

[0076] When the filter net 2 is in the first moving space 414, the filter net 2 is directly opposite to the air inlet 11. At this time, the filter net 2 can filter the air entering the air inlet 11. When the filter net 2 needs to be cleaned, the filter net 2 moves from the first moving space 414 to the transition space 331, so that the cleaning module 3 can clean the part of the filter net 2 located in the transition space 331. When the filter net 2 moves through the transition space 331 to the second moving space 415, the whole filter net 2 passes through the transition space 331, that is to say, the cleaning module 3 has completed a cleaning of the whole filter net 2.

[0077] When the filter net 2 returns from the second moving space 415 to the first moving space 414 through the transition space 331 again, the cleaning module 3 cleans the part of the filter net 2 located in the transition space 331 again. When the filter net 2 completely returns to the first moving space 414, it is equivalent to that the cleaning module 3 has carried out a second cleaning on the filter net 2, effectively improving the cleaning effect on the filter net 2.

[0078] In some further embodiments, in the height direction, the first moving space 414 and the second moving space 415 are stacked.

[0079] Through the above technical solutions, the space occupied by the mounting bracket 4 is reduced, the utilization rate of the internal space of the air conditioner indoor unit 100 is effectively improved, and through this technical solution, the filter net 2 can also play a role in filtering air when it is in the second moving space 415.

[0080] In some embodiments, the frame portion includes a first frame body 411, a second frame body 412, and a third frame body 413 arranged in a stacked manner. A first moving space 414 is defined between the first frame body 411 and the second frame body 412, and a second moving space 415 is defined between the second frame body 412 and the third frame body 413.

[0081] By assembling the first frame body 411, the second frame body 412, and the third frame body 413 into the frame portion, it is beneficial to reduce the mold opening difficulty and cost.

[0082] Refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the first frame body 411, the second frame body 412, and the third frame body 413 are connected by glue or fasteners; in other embodiments, the first frame body 411, the second frame body 412, and the third frame body 413 are detachably connected by a first snap 4111 structure, which is beneficial for later maintenance or replacement.

The second buckles 423 are clamped in the second positioning holes 4112 to enhance the stability of the connection among the framework 42, the first frame body 411, and the third frame body 413.

[0090] Refer to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the air conditioner indoor unit 100 further includes a driving device 5. The driving device 5 is used to cooperate with the filter net 2 to drive the movement of the filter net 2.

[0091] By providing the driving device 5, the air conditioner indoor unit 100 can automatically drive the filter net 2 to move to the cleaning module 3 for cleaning, without the user moving the filter net 2, improving the automation performance of the air conditioner indoor unit 100.

[0092] Refer to Figure 7 , Figure 8 and Figure 9, in some embodiments, the driving device 5 is mounted to the framework 42. The driving device 5 includes a driving gear 51 located within the communication space 421. The filter net 2 includes a transmission portion 21. The driving gear 51 is meshed and cooperated with the transmission portion 21 so as to be adapted to drive the filter net 2 to move.

[0093] Through the above technical solution, by only controlling the rotation direction and rotation angle of the driving gear 51, the moving direction and moving accuracy of the filter net 2 can be well controlled. For example, when the driving gear 51 rotates counterclockwise, the filter net 2 can be driven to move towards the second moving space 415, and when the driving gear 51 rotates clockwise, the filter net 2 can be driven to move towards the first moving space 414, effectively improving the moving stability of the filter net 2.

[0094] Referring to Figure 7 and Figure 8 , the driving gear 51 divides the communication space 421 into a first part 4211 and a second part 4212. The two ends of the first part 4211 are respectively communicated with the first moving space 414 and the first end 3311 of the transition space 331, and the two ends of the second part 4212 are respectively communicated with the second moving space 415 and the second end 3312 of the transition space 331.

[0095] When the filter net 2 is within the first moving space 414, a part of the filter net 2 extends into the first part 4211 to be meshed and cooperated with the driving gear 51.

[0096] When the air conditioner indoor unit 100 cleans the filter net 2, the driving device 5 drives the driving gear 51 to rotate counterclockwise. The filter net 2 moves from the first moving space 414 to the first part 4211, and then enters the transition space 331 through the first end 3311 of the transition space 331, that is, enters the interior of the cleaning housing 31. The cleaning assembly 32 cleans the filter net 2, and then the filter net 2 enters the second part 4212 through the second end 3312 of the transition space 331 and is meshed with the driving gear 51 again, improving the stability of the driving gear 51 to drive the filter net 2 to move. Finally, the filter net 2 within the second part 4212 enters the second moving space 415 under the drive of the driving gear 51. When the filter net 2 is located within the second moving space 415, a part of the filter net 2 is located within the second part 4212 and is meshed with the driving gear 51. Then the driving gear 51 rotates clockwise to drive the filter net 2 to return to the first moving space 414 along the original path.

[0097] Referring to Figure 7 , Figure 8 and Figure 9, in some embodiments, engaging teeth extending along the length direction of the filter net 2 are provided at both ends in the width direction of the filter net 2 to define a transmission portion 21. Two driving gears 51 are correspondingly provided on the driving device 5, and the two driving gears 51 are distributed at both ends in the width direction of the filter net 2, and each driving gear 51 is in meshing engagement with the corresponding transmission portion 21.

[0098] In the above technical solution, the transmission portion 21 is engaging teeth extending along the length direction of the filter net 2, which improves the stability of the meshing engagement between the transmission portion 21 and the driving gear 51, and the transmission portions 21 cooperating with the driving gears 51 are provided at both ends in the width direction of the filter net 2. When the driving device 5 works, both ends in the width direction of the filter net 2 are driven by the driving gears 51, effectively ensuring the stability of the movement of the filter net 2.

[0099] In some embodiments, the thickness of the filter net 2 is A, and the thickness of the engaging teeth is B, and A + B satisfies: 2.2 mm ≤ A + B ≤ 2.7 mm; the thicknesses of the first moving space 414 and the second moving space 415 are both H, and H satisfies: 3.5 mm ≤ H1 ≤ 4.5 mm.

[0100] By the above technical solution, the thickness of the filter net 2 and the thickness of the moving space are limited. While ensuring the smooth movement of the filter net 2, the possibility of deformation of the filter net 2 is reduced, and the stability of the movement of the filter net 2 is ensured.

[0101] In some specific embodiments, the thickness of the filter net 2 is 0.6 mm; the thickness of the engaging teeth is 1.8 mm, that is, A + B is 2.4 mm; the thickness of the first moving space 414 is 3.8 mm, and the thickness of the second moving space 415 is 4 mm.

[0102] In other embodiments, the thickness of the filter net 2 can also be other dimensions such as 0.65 mm, 0.7 mm, 0.8 mm, etc.; the thickness of the engaging teeth can also be other dimensions such as 1.85 mm, 1.9 mm, 2 mm, etc.; the thicknesses of the first moving space 414 and the second moving space 415 can also be other dimensions such as 4 mm, 4.2 mm, 4.5 mm, etc.

[0103] Refer to Figure 7 , Figure 8 and Figure 9 , in some embodiments, the driving device 5 further includes a transmission shaft 52 that rotates synchronously with the driving gears 51, and the two driving gears 51 are respectively installed at both ends of the transmission shaft 52. A plurality of protrusions are circumferentially and spacedly arranged on the outer peripheral wall of the transmission shaft 52, and the protrusions are adapted to abut against the filter net 2.

[0104] With the above technical solution, when the driving device 5 drives the filter net 2 to move, it is driven not only by two driving gears 51, but also by the contact between the protrusions on the transmission shaft 52 and the filter net 2. By adding the transmission shaft 52 for transmission, the stress area of the filter net 2 is increased, avoiding deformation due to concentrated stress on the filter net 2 and extending the service life of the filter net 2.

[0105] Referring to Figure 7 , Figure 8 and Figure 9 , in some specific embodiments, the protrusions on the transmission shaft 52 extend along the length direction of the transmission shaft 52, and the number of protrusions on the transmission shaft 52 is the same as the number of teeth on the driving gear 51, and the multiple protrusions on the transmission shaft 52 correspond one by one to the multiple teeth on the driving gear 51, and each tooth is located in the extending direction of the corresponding protrusion.

[0106] In the above technical solution, the protrusions on the transmission shaft 52 extend along the length direction of the transmission shaft 52, increasing the contact area between the protrusions and the filter net 2 and reducing the risk of deformation of the filter net 2; each tooth is located in the extending direction of the corresponding protrusion, making the directions of the forces received by each part of the filter net 2 in the width direction the same, further reducing the risk of deformation of the filter net 2.

[0107] In some specific embodiments, a plug hole 521 is provided at the end of the transmission shaft 52, and a plug shaft 511 is provided on the driving gear 51. The plug shaft 511 is inserted into the plug hole 521 to realize the connection between the driving gear 51 and the transmission shaft 52.

[0108] With the above technical solution, when installing the driving gear 51 on the transmission shaft 52, only need to insert the plug shaft 511 into the plug hole 521, which is convenient and fast, improving the assembly efficiency of the indoor unit 100 of the air conditioner.

[0109] In some specific embodiments, a transmission protrusion 522 is provided on the inner wall of the plug hole 521, and a transmission slot 512 is correspondingly provided on the plug shaft 511. The transmission protrusion 522 is clamped in the transmission slot 512 so that the transmission shaft 52 and the driving gear 51 can rotate synchronously.

[0110] In some embodiments, the driving device 5 further includes a first motor 53. The first motor 53 is disposed outside the skeleton 42, and a first transmission gear 54 is provided on the output shaft of the first motor 53. The first transmission gear 54 meshes with a second transmission gear 55.

[0111] A third transmission gear 56 is provided on the transmission shaft 52 and is located outside the framework 42. The third transmission gear 56 meshes with the second transmission gear 55. When the first motor 53 drives the first transmission gear 54 to rotate, the first transmission gear 54 drives the second transmission gear 55 to rotate, and the second transmission gear 55 drives the third transmission gear 56 to rotate, thereby driving the transmission shaft 52 and the drive gear 51 on the transmission shaft 52 to rotate.

[0112] In the embodiment of the present invention, the first motor 53 is arranged outside the framework 42, avoiding the first motor 53 occupying the space inside the framework 42, which is beneficial to the miniaturization of the framework 42.

[0113] Refer to Figure 6 、 Figure 8 and Figure 9 In some specific embodiments, the first motor 53 is mounted on the mounting bracket 4 by screws. A shielding cover 57 is also provided on the mounting bracket 4. The first transmission gear 54, the second transmission gear 55, and the third transmission gear 56 are all located inside the shielding cover 57.

[0114] In the above technical solution, the first transmission gear 54, the second transmission gear 55, and the third transmission gear 56 are shielded by the shielding cover 57, preventing external objects from interfering with the transmission gears and affecting the transmission, thereby improving the stability of the driving device 5.

[0115] Refer to Figure 6 、 Figure 7 and Figure 8 In some embodiments, the cleaning assembly 32 includes a vibration device. The cleaning housing 31 includes a cleaning tank 3121 for containing cleaning liquid. The vibration device is adapted to drive the cleaning liquid in the cleaning tank 3121 to vibrate to clean the part of the filter screen 2 located in the cleaning liquid.

[0116] Through the above technical solution, when the cleaning module 3 cleans the filter screen 2, the dirt on the filter screen 2 falls off under the continuous flushing of the vibrating cleaning liquid, improving the cleaning efficiency of the filter screen 2. Moreover, the dirt falling off from the filter screen 2 is collected in the cleaning liquid and will not reattach to the filter screen 2 due to diffusion, effectively ensuring the cleaning effect of the cleaning module 3.

[0117] When the cleaning module 3 finishes cleaning the filter screen 2, the user can remove the cleaning housing 31 from the mounting bracket 4, then pour out the dirty cleaning liquid in the cleaning tank 3121, replenish clean cleaning liquid into the cleaning tank 3121, and finally install the cleaning housing 31 back onto the mounting bracket 4, so that the cleaning module 3 can continue to clean the filter screen 2 subsequently.

[0118] It should be noted that the cleaning liquid can be ordinary water, which is convenient for users to obtain materials; the cleaning liquid can also be a liquid added with a cleaning agent to improve the cleaning effect of the cleaning module 3.

[0119] In some other usage scenarios of the present invention, a bactericide can also be added to the cleaning liquid so that while the cleaning component 32 cleans the filter net 2, it can also sterilize the filter net 2, improving the safety of using the indoor unit 100 of the air conditioner.

[0120] In still other usage scenarios of the present invention, an aromatherapy can also be added to the cleaning liquid, enabling the indoor unit 100 of the air conditioner to also have an aromatherapy function, which is beneficial to improving the air quality in the room.

[0121] In some specific embodiments, the vibration device is configured as an ultrasonic generating device. The ultrasonic generating device can drive the cleaning liquid in the cleaning tank 3121 to vibrate at a high frequency, causing the cleaning liquid to form vacuum microbubbles on the surface of the filter net 2. The energy generated when the cavitation bubbles burst impacts the dirt on the filter net 2, causing the dirt to fall off, greatly improving the cleaning effect of the cleaning component 32.

[0122] In some specific embodiments, the ultrasonic generating device includes a driving plate 321 and a vibrating plate 322. The driving plate 321 is electrically connected to the vibrating plate 322. The driving plate 321 is adapted to emit a first set frequency to drive the vibrating plate 322 to vibrate at a high frequency, so as to drive the cleaning liquid in the cleaning tank 3121 to vibrate synchronously, causing the cleaning liquid to form vacuum microbubbles on the surface of the filter net 2, and the energy generated when the cavitation bubbles burst impacts the dirt to fall off.

[0123] Among them, the value of the first set frequency can be 20 - 60 KHz. For example, the first set frequency can be 20 KHz, 35 KHz, 40 KHz, 45 KHz, 60 KHz, etc. If the first set frequency is lower than 20 KHz, the cleaning effect of the cleaning component 32 on the filter net 2 is poor; if the first set frequency is higher than 60 KHz, the requirements for the ultrasonic generating device are higher, increasing the cost and energy consumption of the cleaning component 32.

[0124] In some specific embodiments, the first set frequency is 45 KHz, which not only reduces the cost of the cleaning component 32 but also ensures a better cleaning effect on the filter net 2 at this frequency.

[0125] Refer to Figure 6 、 Figure 7 and Figure 8, in some embodiments, the frame portion is provided with a first moving space 414 and a second moving space 415. A guiding component 33 is arranged in the cleaning housing 31. The guiding component 33 is provided with a transition space 331. The first moving space 414 communicates with the second moving space 415 through the transition space 331, so that the filter net 2 in the first moving space 414 can move into the second moving space 415 through the transition space 331.

[0126] The guiding component 33 extends into the cleaning tank 3121, and the guiding component 33 is provided with a plurality of hollow areas 332 communicating with the transition space 331, so that the cleaning liquid in the cleaning tank 3121 can enter the transition space 331 through the hollow areas 332 to clean the filter net 2 in the transition space 331.

[0127] In some specific embodiments, the plurality of hollow areas 332 are arranged at intervals along the width direction of the filter net 2.

[0128] Through the above technical solution, each part in the width direction of the filter net 2 has a better cleaning effect.

[0129] In addition to the technical solution of arranging the hollow areas 332 on the guiding component 33, in some other embodiments, the guiding component 33 is a water-permeable material structural member, and the cleaning liquid in the cleaning tank 3121 can pass through the guiding component 33 into the transition space 331 to clean the filter net 2.

[0130] In some embodiments, the guiding component 33 is provided with a second guiding surface 333, and the second guiding surface 333 is adapted to guide the filter net 2 into the transition space 331, improving the smoothness of the movement of the filter net 2.

[0131] Refer to Figure 7 , in some specific embodiments, the openings at each end of the transition space 331 gradually increase in the direction towards the corresponding moving space to form a second guiding surface 333. That is to say, the inner walls of the openings at the ends of the transition space 331 are all formed as the second guiding surface 333. When any part of the end of the filter net 2 contacts the inner wall of the opening at the end of the transition space 331, the inner wall of the opening at the end of the transition space 331 can guide the filter net 2 into the transition space 331.

[0132] In some embodiments, the guiding component 33 is arranged in the cleaning tank 3121. The openings at both ends of the transition space 331 are both arranged upward to communicate with the communication space 421. The two ends of the transition space 331 are respectively a first end 3311 and a second end 3312. The first end 3311 communicates with the first moving space 414 through a first part 4211, and the second end 3312 communicates with the second moving space 415 through a second part 4212.

[0133] Refer toFigure 6 , Figure 7 and Figure 8 , in some specific embodiments, the cleaning housing 31 includes a housing 311 and a cylinder block 312. A second opening is provided at the top of the housing 311. The cylinder block 312 is disposed within the housing 311, and the cylinder block 312 defines a cleaning tank 3121 with an upward opening. An installation space 3111 for the ultrasonic generating device is defined between the bottom wall of the housing 311 and the bottom wall of the cylinder block 312.

[0134] The ultrasonic generating device includes a driving plate 321 and a vibrating plate 322. The driving plate 321 is mounted on the bottom wall of the housing 311, and the vibrating plate 322 is vacuum-bonded to the bottom wall of the cylinder block 312.

[0135] The edge of the top opening of the cylinder block 312 is turned outwards to form a first overlapping portion 3122, and the first overlapping portion 3122 overlaps at the edge of the second opening of the housing 311.

[0136] The cleaning housing 31 further includes a mounting portion 313. The mounting portion 313 is ultrasonically fixed to the housing 311, and the first overlapping portion 3122 is clamped between the mounting portion 313 and the housing 311, so that the cylinder block 312 is stably mounted within the housing 311.

[0137] The mounting portion 313 is detachably connected to the skeleton 42, so that the cleaning housing 31 is detachably connected to the mounting bracket 4.

[0138] A part of the structure of the guiding assembly 33 extends in the horizontal direction to form a second overlapping portion 334. The second overlapping portion 334 is clamped between the mounting portion 313 and the first overlapping portion 3122, so that the guiding assembly 33 is stably mounted within the housing 311.

[0139] Referring to Figure 6 , Figure 7 and Figure 8 , in some embodiments, the cleaning housing 31 is provided with a first limiting member 314, and the mounting bracket 4 is provided with a second limiting member 43. The first limiting member 314 and the second limiting member 43 are inserted and matched to limit the cleaning housing 31 to the mounting bracket 4.

[0140] When the cleaning housing 31 needs to be mounted to the mounting bracket 4, move the cleaning housing 31 towards the mounting bracket 4 and make the first limiting member 314 and the second limiting member 43 inserted and matched; when the cleaning housing 31 needs to be disassembled from the mounting bracket 4, move the cleaning housing 31 in a direction away from the mounting bracket 4 and make the second limiting member 43 disengage from the first limiting member 314.

[0141] Through the above technical solution, the connection manner between the cleaning housing 31 and the mounting bracket 4 is simple and convenient for the user to operate. Moreover, the first limiting member 314 and the second limiting member 43 can bear the gravity of the cleaning housing 31, improving the stability of the cleaning housing 31.

[0142] In some embodiments, one of the first limiting member 314 and the second limiting member 43 is a plug-in member 431 and the other is a plug-in groove 3141. The plug-in member 431 is located in the plug-in groove 3141 and abuts against the inner wall of the plug-in groove 3141 to support the cleaning housing 31.

[0143] In the above technical solution, by abutting the plug-in member 431 against the inner wall of the plug-in groove 3141, the effect of supporting the cleaning housing 31 can be achieved.

[0144] In some specific embodiments, the first limiting member 314 is the plug-in member 431 and the second limiting member 43 is the plug-in groove 3141.

[0145] In other embodiments, the first limiting member 314 is the plug-in groove 3141 and the second limiting member 43 is the plug-in member 431. Because during the process of inserting the plug-in member 431 into the plug-in groove 3141, the plug-in member 431 is prone to collide with the edge of the plug-in groove 3141, and the probability of damage to the plug-in groove 3141 is greater than that of the plug-in member 431. In the embodiment of the present invention, the first limiting member 314 is the plug-in groove 3141, that is to say, the plug-in groove 3141 can be disassembled along with the cleaning housing 31, facilitating the repair or replacement of the plug-in groove 3141.

[0146] In some embodiments, the plug-in groove 3141 extends in the front-back direction. The plug-in groove 3141 has an inner bottom wall and an inner top wall oppositely arranged in the up-down direction. Abutting ribs 4311 are provided on the upper side of the plug-in member 431. The lower side of the plug-in member 431 abuts against the inner bottom wall, and the upper side of the plug-in member 431 abuts against the inner top wall through the abutting ribs 4311, effectively reducing the possibility of the cleaning housing 31 shaking and improving the stability of the cleaning housing 31. Moreover, the upper side of the plug-in member 431 abuts against the inner top wall through the abutting ribs 4311, reducing the thickness of the body of the plug-in member 431 and lowering the cost of the air conditioner indoor unit 100.

[0147] In some embodiments, a plurality of plug-in grooves 3141 are provided, and a plurality of plug-in members 431 are also correspondingly provided. Each plug-in member 431 is inserted into a corresponding plug-in groove 3141.

[0148] Through the cooperation of multiple groups of plug-in members 431 and plug-in grooves 3141, the stability of the relative sliding of the cleaning housing 31 with respect to the mounting bracket 4 is effectively improved.

[0149] In some specific embodiments, insertion slots 3141 are provided on both the left and right sides of the installation part 313. The two insertion slots 3141 are arranged opposite to each other and both extend in the front-rear direction. Corresponding to the bottom of the framework 42, two insertion members 431 are provided, and each insertion member 431 is inserted into the corresponding insertion slot 3141.

[0150] In the above technical solution, not only are multiple insertion slots 3141 and insertion members 431 provided to improve the sliding stability of the cleaning housing 31 relative to the installation bracket 4, but also the multiple insertion slots 3141 are distributed on both the left and right sides of the cleaning housing 31, so that the insertion slots 3141 and the insertion members 431 can support the cleaning housing 31 on both the left and right sides of the cleaning housing 31, effectively improving the stability when the cleaning housing 31 is installed on the installation bracket 4.

[0151] In some embodiments, the insertion slot 3141 is provided with a first guiding surface 3142 for guiding the insertion of the insertion member 431, which improves the smoothness of the insertion of the insertion member 431.

[0152] In some embodiments, the cleaning housing 31 is provided with a first positioning member 315, and the installation bracket 4 is provided with a second positioning member 44. The first positioning member 315 and the second positioning member 44 are in positioning cooperation to limit the movement of the cleaning housing 31 relative to the installation bracket 4, and improve the stability when the cleaning housing 31 is installed on the installation bracket 4.

[0153] In some specific embodiments, one of the first positioning member 315 and the second positioning member 44 is a positioning protrusion 3151 and the other is a positioning groove 441. The positioning protrusion 3151 is located in the positioning groove 441 to position the cleaning housing 31.

[0154] The structures of the first positioning member 315 and the second positioning member 44 in the above technical solution are simple, reducing the cost of the air conditioner indoor unit 100.

[0155] In some specific embodiments, the first positioning member 315 is a positioning protrusion 3151 extending in the front-rear direction provided on the top surface of the guiding assembly 33, and the second positioning member 44 is a positioning groove 441 extending in the front-rear direction at the bottom of the framework 42. The positioning protrusion 3151 is located in the positioning groove 441 to limit the displacement of the cleaning housing 31 in the left-right direction and improve the stability of the cleaning housing 31.

[0156] Referring to Figure 1 、 Figure 3 and Figure 5 , in some embodiments, a pulling slot 335 is further provided on the cleaning housing 31 to facilitate the user to pull the cleaning housing 31.

[0157] In some specific embodiments, the drawing slot 335 is provided on the front side of the mounting portion 313, so as to facilitate the user to draw out the cleaning housing 31 from the front side of the front frame 13. In some other embodiments, the drawing slot 335 may also be provided on the front side of the outer housing 311, as long as it is convenient for the user to draw.

[0158] The air conditioner according to an embodiment of the present invention includes the air conditioner indoor unit 100 in the above technical solution.

[0159] In the air conditioner according to an embodiment of the present invention, the filter net 2 can move to the cleaning module 3 for cleaning, without the need for the user to manually clean the filter net 2, improving the convenience of using the air conditioner; when cleaning the filter net 2, the dirt on the filter net 2 is collected in the cleaning housing 31, avoiding the spread of dirt in the machine housing 1; the cleaning housing 31 can be disassembled, facilitating the user to handle the dirt in the cleaning housing 31. The method of handling the dirt in the cleaning housing 31 is simple, without the need to additionally provide a special structure for handling the dirt in the cleaning housing 31 in the air conditioner indoor unit 100, reducing the cost of the air conditioner.
