[0057] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, the filter 2 can be moved to the cleaning module 3 for cleaning, and the user does not need to manually clean the filter 2, thereby improving the convenience of using the air-conditioning indoor unit 100; when cleaning the filter 2, the dirt on the filter 2 is collected in the cleaning shell 31, thereby preventing the dirt from spreading in the casing 1; the cleaning shell 31 can be disassembled, which is convenient for the user to handle the dirt in the cleaning shell 31. The method for handling the dirt inside the cleaning shell 31 is simple, and there is no need to set up a structure in the air-conditioning indoor unit 100 specifically for handling the dirt in the cleaning shell 31, thereby reducing the cost of the air-conditioning indoor unit 100.

[0058] It should be noted that the cleaning shell 31 is a part of the cleaning module 3, and the cleaning module 3 also includes a cleaning component 32. The cleaning shell 31 is detachably arranged on the casing 1, and the cleaning component 32 can be fixedly arranged on the casing 1 or detachably arranged on the casing 1.

[0059] For example, in some embodiments, the cleaning assembly 32 is fixed to the housing 1, and the cleaning shell 31 is detachably arranged on the housing 1. When the cleaning shell 31 is installed on the housing 1, the cleaning assembly 32 is located in the cleaning shell 31. In the embodiment of the utility model, when the user cleans the dirt in the cleaning shell 31, he only needs to disassemble the cleaning shell 31.

[0062] When the user needs to clean the cleaning shell 31, the user removes the cleaning shell 31 from the casing 1 and takes the cleaning shell 31 out of the accommodating cavity through the first opening 131; when the user has finished cleaning the cleaning shell 31, the user inserts the cleaning shell 31 into the accommodating cavity through the first opening 131 and installs it on the casing 1.

[0063] In the above technical solution, by providing the first opening 131 specifically for installing and removing the cleaning shell 31, the user does not need to disassemble the casing 1 when installing and removing the cleaning shell 31, thereby improving the convenience of using the air conditioner indoor unit 100.

[0064] The first opening 131 in the embodiment of the utility model can be set at the front side of the face frame 13, and can also be set at the left side, right side, bottom side, etc. of the face frame 13, as long as it is convenient for users to install and remove the cleaning shell 31.

[0065] Reference Figure 1 , Figure 2 and Figure 3 In some further embodiments, the first opening 131 can be opened or closed. When the cleaning housing 31 needs to be installed or removed, the first opening 131 is opened, and when the cleaning housing 31 does not need to be processed, the first opening 131 is closed to prevent external dust, insects and other substances from entering the accommodating cavity and affecting the operation of the air conditioner indoor unit 100.

[0066] The first opening 131 in the embodiment of the utility model is designed to be closable. When there is no need to clean the shell 31, the first opening 131 is in a closed state, which not only avoids the risk of external substances affecting the internal structure of the air-conditioning indoor unit 100, but also improves the aesthetics of the air-conditioning indoor unit 100.

[0067] Reference Figure 1 , Figure 2 and Figure 3In some embodiments, the housing 1 further includes a panel 14, which is rotatably disposed on the face frame 13 to expose or shield the face frame 13. When a problem occurs with the air conditioner indoor unit 100, the face frame 13 can be opened by rotating the panel 14, so that the user can check and repair the internal structure of the air conditioner indoor unit 100.

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

[0069] In the embodiment of the utility model, the first opening 131 is arranged on the front side of the face frame 13 so that the panel 14 can also play the role of opening or closing the first opening 131. There is no need to set other structures for opening or closing the first opening 131, thereby simplifying the structure of the air-conditioning indoor unit 100.

[0070] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments, the housing 1 includes a mounting bracket 4 , the filter 2 is movably disposed on the mounting bracket 4 , and the cleaning shell 31 is detachably disposed on the mounting bracket 4 .

[0071] In the above technical solution, the filter 2 can be movably arranged on the mounting bracket 4, which limits the movement mode of the filter 2 and improves the stability of the filter 2. The cleaning shell 31 can be detachably arranged on the mounting bracket 4, shortening the distance between the cleaning module 3 and the filter 2, making it convenient for the filter 2 to move through the mounting bracket 4 to the cleaning module 3 for cleaning.

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

[0073] The skeleton 42 is installed to one end of the frame part 41 , and the cleaning shell 31 is detachably arranged on the skeleton 42 , that is, the cleaning shell 31 is arranged at one end of the frame part 41 , so as to prevent the cleaning module 3 from affecting the air intake of the air conditioner indoor unit 100 .

[0074] The skeleton 42 connects the moving space and the inner space of the cleaning housing 31 so that the filter 2 can be moved into the cleaning housing 31. When the filter 2 needs to be cleaned, the filter 2 moves along the moving space to the skeleton 42, and then enters the inner space of the cleaning housing 31 through the skeleton 42, so that the cleaning assembly 32 in the cleaning housing 31 can clean the filter 2.

[0075] Reference Figure 4 , Figure 6 and Figure 7 In some embodiments, the frame portion is provided with a first movable space 414 and a second movable space 415, a guide assembly 33 is provided in the cleaning shell 31, the guide assembly 33 is provided with a transition space 331, and the first movable space 414 is connected with the second movable space 415 through the transition space 331, so that the filter net 2 in the first movable space 414 moves to the second movable space 415 through the transition space 331.

[0076] When the filter 2 is in the first moving space 414, the filter 2 is directly opposite to the air inlet 11, and the filter 2 can filter the air entering the air inlet 11. When the filter 2 needs to be cleaned, the filter 2 moves from the first moving space 414 to the transition space 331, so that the cleaning module 3 can clean the portion of the filter 2 located in the transition space 331. When the filter 2 moves to the second moving space 415 through the transition space 331, the entire filter 2 passes through the transition space 331, that is, the cleaning module 3 completes the cleaning of the entire filter 2.

[0077] When the filter 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 2 located in the transition space 331 again. When the filter 2 completely returns to the first moving space 414, it is equivalent to the cleaning module 3 cleaning the filter 2 for the second time, which effectively improves the cleaning effect of the filter 2.

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

[0079] Through the above technical solution, the space occupied by the mounting bracket 4 is reduced, and the utilization rate of the internal space of the air-conditioning indoor unit 100 is effectively improved. In addition, through this technical solution, the filter screen 2 can also filter the air when it is in the second moving space 415.

[0092] Reference Figure 7 , Figure 8 and Fig. 9In some embodiments, the driving device 5 is mounted to the frame 42, and the driving device 5 includes a driving gear 51 located in the connecting space 421, and the filter screen 2 includes a transmission part 21, and the driving gear 51 is meshed with the transmission part 21 to drive the filter screen 2 to move.

[0093] Through the above technical solution, the moving direction and moving accuracy of the filter 2 can be well controlled by simply controlling the rotation direction and rotation angle of the driving gear 51. For example, if the driving gear 51 rotates counterclockwise, the filter 2 can be driven to move toward the second moving space 415, and if the driving gear 51 rotates clockwise, the filter 2 can be driven to move toward the first moving space 414, which effectively improves the stability of the movement of the filter 2.

[0094] Reference Figure 7 and Figure 8 The driving gear 51 divides the connecting space 421 into a first part 4211 and a second part 4212, wherein both ends of the first part 4211 are respectively connected to the first moving space 414 and the first end 3311 of the transition space 331, and both ends of the second part 4212 are respectively connected to the second moving space 415 and the second end 3312 of the transition space 331.

[0095] When the filter screen 2 is in the first moving space 414 , a portion of the filter screen 2 extends to the first portion 4211 to mesh with the driving gear 51 .

[0096] When the air conditioner indoor unit 100 cleans the filter 2, the driving device 5 drives the driving gear 51 to rotate counterclockwise, and the filter 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, and the cleaning assembly 32 cleans the filter 2, and then the filter 2 enters the second part 4212 through the second end 3312 of the transition space 331 and meshes with the driving gear 51 again, thereby improving the stability of the driving gear 51 driving the filter 2 to move, and finally the filter 2 in the second part 4212 enters the second moving space 415 under the drive of the driving gear 51. When the filter 2 is located in the second moving space 415, a part of the filter 2 is located in the second part 4212 and meshes with the driving gear 51. Then the driving gear 51 rotates clockwise to drive the filter 2 to return to the first moving space 414 along the original path.

[0097] Reference Figure 7 , Figure 8 and Fig. 9In some embodiments, the ends of the filter screen 2 in the width direction are provided with meshing teeth extending along the length direction of the filter screen 2 to define the transmission part 21. The driving device 5 is correspondingly provided with two driving gears 51, which are distributed at both ends of the filter screen 2 in the width direction, and each driving gear 51 is meshed with the corresponding transmission part 21.

[0098] In the above technical solution, the transmission part 21 is a meshing tooth extending along the length direction of the filter screen 2, which improves the stability of the meshing cooperation between the transmission part 21 and the driving gear 51, and the transmission part 21 cooperating with the driving gear 51 is provided at both ends of the width direction of the filter screen 2. When the driving device 5 is working, both ends of the width direction of the filter screen 2 are driven by the driving gear 51, which effectively ensures the stability of the movement of the filter screen 2.

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

[0100] The above technical solution limits the thickness of the filter screen 2 and the thickness of the moving space, thereby ensuring smooth movement of the filter screen 2 and reducing the possibility of deformation of the filter screen 2, thereby ensuring the stability of the movement of the filter screen 2.

[0101] In some specific embodiments, the thickness of the filter screen 2 is 0.6 mm; the thickness of the meshing 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 screen 2 can also be 0.65mm, 0.7mm, 0.8mm or other sizes; the thickness of the meshing teeth can also be 1.85mm, 1.9mm, 2mm or other sizes; the thickness of the first moving space 414 and the second moving space 415 can also be 4mm, 4.2mm, 4.5mm or other sizes.

[0103] Reference Figure 7 , Figure 8 and Fig. 9 In some embodiments, the driving device 5 further comprises a transmission shaft 52 that rotates synchronously with the driving gear 51, and the two driving gears 51 are respectively mounted at both ends of the transmission shaft 52. The outer peripheral wall of the transmission shaft 52 is provided with a plurality of protrusions at intervals along the circumferential direction, and the protrusions are suitable for abutting against the filter screen 2.

[0104] Through the above technical solution, when the driving device 5 drives the filter screen 2 to move, it is driven not only by the two driving gears 51, but also by the contact between the protrusion on the transmission shaft 52 and the filter screen 2. By adding the transmission shaft 52 for transmission, the force area of ​​the filter screen 2 is increased, the filter screen 2 is prevented from being deformed due to concentrated force, and the service life of the filter screen 2 is extended.

[0105] Reference Figure 7 , Figure 8 and Fig. 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-to-one to the multiple teeth on the driving gear 51, and each tooth is located in the extension direction of the corresponding protrusion.

[0106] In the above technical solution, the protrusion on the transmission shaft 52 extends along the length direction of the transmission shaft 52, thereby increasing the contact area between the protrusion and the filter screen 2 and reducing the risk of deformation of the filter screen 2; each tooth is located in the extension direction of the corresponding protrusion, so that the directions of the forces applied to each part of the filter screen 2 in the width direction are the same, further reducing the risk of deformation of the filter screen 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 at the driving gear 51 . The plug shaft 511 is inserted into the plug hole 521 to achieve the connection between the driving gear 51 and the transmission shaft 52 .

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

[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 , which is disposed outside the skeleton 42 , and an output shaft of the first motor 53 is provided with a first transmission gear 54 , which is meshed with a second transmission gear 55 .

[0111] The transmission shaft 52 is provided with a third transmission gear 56 located outside the frame 42, and the third transmission gear 56 is meshed 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 driving gear 51 on the transmission shaft 52 to rotate.

[0112] In the embodiment of the utility model, the first motor 53 is arranged outside the frame 42 to avoid the first motor 53 occupying the space inside the frame 42 , which is conducive to the miniaturization of the frame 42 .

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

[0114] The above technical solution shields the first transmission gear 54 , the second transmission gear 55 and the third transmission gear 56 through the shielding cover 57 , thereby preventing foreign objects from interfering with the transmission gears and affecting transmission, thereby improving the stability of the driving device 5 .

[0115] Reference Figure 6 , Figure 7 and Figure 8 In some embodiments, the cleaning component 32 includes a vibration device, the cleaning shell 31 includes a cleaning tank 3121 for holding a cleaning liquid, and the vibration device is suitable for driving the cleaning liquid in the cleaning tank 3121 to vibrate to clean the portion 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, thereby improving the efficiency of cleaning the filter screen 2, and the dirt that falls off the filter screen 2 is collected in the cleaning liquid and will not adhere to the filter screen 2 again due to diffusion, thereby effectively ensuring the cleaning effect of the cleaning module 3.

[0117] When the cleaning module 3 completes cleaning the filter 2, the user can remove the cleaning shell 31 from the mounting bracket 4, then pour out the dirty cleaning liquid in the cleaning tank 3121, then add clean cleaning liquid to the cleaning tank 3121, and finally install the cleaning shell 31 on the mounting bracket 4, so that the cleaning module 3 can continue to clean the filter 2 subsequently.

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

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

[0120] In some other usage scenarios of the present invention, aromatherapy can be added to the cleaning liquid so that the air-conditioning indoor unit 100 also has an aromatherapy function, which is beneficial to improving the indoor air quality.

[0121] In some specific embodiments, the vibration device is constructed as an ultrasonic generating device, which can drive the cleaning liquid in the cleaning tank 3121 to vibrate at a high frequency, so that the cleaning liquid forms small vacuum bubbles on the surface of the filter screen 2. The energy generated when the cavitation bubbles burst impacts the dirt on the filter screen 2, so that the dirt falls off, thereby 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 vibration plate 322. The driving plate 321 is electrically connected to the vibration plate 322. The driving plate 321 is suitable for emitting a first set frequency to drive the vibration plate 322 to vibrate at a high frequency, so as to drive the cleaning liquid in the cleaning tank 3121 to vibrate synchronously, so that the cleaning liquid forms small vacuum bubbles on the surface of the filter screen 2, and the cavitation bubbles burst to generate energy impact to remove the dirt.

[0123] The value of the first set frequency may be 20 to 60 KHz, for example, the first set frequency may 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 screen 2 is poor; if the first set frequency is higher than 60 KHz, the requirements for the ultrasonic generator are higher, which increases 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 screen 2 at this frequency.

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

In other words, the inner wall of the opening at the end of the transition space 331 is formed as the second guide surface 333, and the end of the filter 2 contacts any part of the inner wall of the opening at the end of the transition space 331, and the inner wall of the opening at the end of the transition space 331 can guide the filter 2 to enter the transition space 331.

An installation space 3111 for an ultrasonic generator is defined between the bottom wall of the outer shell 311 and the bottom wall of the cylinder 312.

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

[0145] In other embodiments, the first stopper 314 is a plug slot 3141, and the second stopper 43 is a plug connector 431. Because the plug connector 431 is easily collided with the edge of the plug slot 3141 during the process of inserting the plug connector 431 into the plug slot 3141, the probability of damage to the plug slot 3141 is greater than the probability of damage to the plug connector 431.
