For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Next, reference is made to Figures 1 - 12 to describe the air conditioner indoor unit 100 according to an embodiment of the present invention.

[0045] Referring to Figure 1 、 Figure 2 and Figure 3 The air conditioner indoor unit 100 according to an embodiment of the present invention includes: a housing 1, an indoor heat exchanger and a driving fan are arranged 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 works, 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, so as to achieve the effect of adjusting the indoor temperature.

[0046] The air conditioner indoor unit 100 according to an embodiment of the present invention 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 and improve the indoor air quality. The cleaning module 3 is arranged on the housing 1 and is used to clean the filter net 2.

[0047] Referring to Figure 3 、 Figure 4 and Figure 5, specifically, the housing 1 includes a mounting bracket 4 that extends in the horizontal direction, and the filter net 2 is movably arranged on the mounting bracket 4. In the horizontal direction, the cleaning module 3 is mounted at the end of the mounting bracket 4 and is located at the bottom of the mounting bracket 4.

[0048] 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. When the filter net 2 needs to be cleaned, the filter net 2 moves towards the cleaning module 3 so that the cleaning module 3 can clean the filter net 2. The cleaning module 3 is arranged at the end of the mounting bracket 4, avoiding the influence of the cleaning module 3 on the air intake of the air conditioner indoor unit 100; the cleaning module 3 is also located at the bottom of the mounting bracket 4, facilitating the movement of the filter net 2 into the cleaning module 3. After the filter net 2 moves horizontally to the end of the mounting bracket 4, it can directly enter the cleaning module 3, improving the efficiency of cleaning the filter net 2.

[0049] The cleaning module 3 includes a cleaning tank 3121 and a vibration device 32. The cleaning tank 3121 is used to hold condensed water, and the filter net 2 can move to be located inside the cleaning tank 3121. The vibration device 32 is adapted to drive the condensed water in the cleaning tank 3121 to vibrate to clean the part of the filter net 2 located in the condensed water.

[0050] Through the above technical solution, when the cleaning module 3 cleans the filter net 2, the dirt on the filter net 2 falls off under the continuous scouring of the vibrating condensed water, improving the efficiency of cleaning the filter net 2. And the dirt falling off from the filter net 2 is collected in the condensed water and will not reattach to the filter net 2 due to diffusion, effectively ensuring the cleaning effect of the cleaning module 3.

[0051] In the air conditioner indoor unit 100 according to an embodiment of the present invention, the filter net 2 can move to the cleaning module 3 for cleaning, eliminating the need for users to manually clean the filter net 2, improving the convenience of using the air conditioner indoor unit 100; the cleaning module 3 is arranged at the end of the mounting bracket 4, avoiding the influence of the cleaning module 3 on the air intake of the air conditioner indoor unit 100; the cleaning module 3 is also located at the bottom of the mounting bracket 4, and after the filter net 2 moves horizontally to the end of the mounting bracket 4, it can directly enter the cleaning module 3, improving the efficiency of cleaning the filter net 2; the cleaning module 3 can clean the filter net 2 through vibrating condensed water, ensuring the cleaning effect of cleaning the filter net 2.

[0052] In some specific embodiments, the vibration device 32 is configured as an ultrasonic generating device. The ultrasonic generating device can drive the condensed water in the cleaning tank 3121 to vibrate at a high frequency, causing vacuum microbubbles to form 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 module.

[0053] In some specific embodiments, the ultrasonic generating device includes a driving board and a vibrating piece 322. The driving board is electrically connected to the vibrating piece 322 and is adapted to emit a first set frequency to drive the vibrating piece 322 to vibrate at a high frequency, so as to drive the condensed water in the cleaning tank 3121 to vibrate synchronously, causing the condensed water to form vacuum microbubbles on the surface of the filter net 2, and the cavitation bubbles burst to generate energy impact to make the dirt fall off.

[0054] Wherein, 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 module 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 module.

[0055] In some specific embodiments, the first set frequency is 45 KHz, which not only reduces the cost of the cleaning module but also ensures a better cleaning effect on the filter net 2 at this frequency.

[0056] 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 disposed opposite to the air inlet 11. The filter net 2 is disposed 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, improving the stability of the movement of the filter net 2.

[0057] The skeleton 42 is mounted to one end of the frame part 41, and the cleaning housing 31 is disposed at the bottom of the skeleton 42. That is to say, the upper and lower ends of the skeleton 42 are respectively communicated with the moving space and the internal space of the cleaning module 3, so that the skeleton 42 can guide the filter net 2 to move into the cleaning tank 3121. When the filter net 2 needs to be cleaned, the filter net 2 moves along the moving space to the skeleton 42 and then enters the cleaning tank 3121 through the skeleton 42, so that the condensed water in the cleaning tank 3121 can clean the filter net 2.

[0058] Referring to Figure 4 、 Figure 5 and Figure 6 In some embodiments, the moving space includes a first moving space 414 and a second moving space 415. A guiding component 33 is provided in the cleaning housing 31, and the guiding component 33 is provided with a transition space 331. 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 can move into the second moving space 415 through the transition space 331.

[0059] When the filter net 2 is within 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 it is necessary to clean the filter net 2, 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 has passed through the transition space 331. That is to say, the cleaning module 3 has completed a cleaning of the whole filter net 2.

[0060] When the filter net 2 returns from the second moving space 415 to the first moving space 414 again through the transition space 331, 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 the cleaning module 3 cleaning the filter net 2 for the second time, effectively improving the cleaning effect on the filter net 2.

[0061] Refer to Figure 4 、 Figure 5 and Figure 6 In some further embodiments, in the height direction, the first moving space 414 and the second moving space 415 are stacked.

[0062] Through the above technical solution, the space occupied by the mounting bracket 4 is reduced, effectively improving the utilization rate of the internal space of the air conditioner indoor unit 100. 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.

[0063] Refer to Figure 4 、 Figure 5 and Figure 6 In some embodiments, the frame part 41 includes a first frame body 411, a second frame body 412 and a third frame body 413 which are stacked. 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.

[0064] By assembling the first frame body 411, the second frame body 412 and the third frame body 413 into the frame part 41, it is beneficial to reduce the mold opening difficulty and cost.

[0065] In some embodiments, the first housing 411, the second housing 412, and the third housing 413 are connected by glue or fasteners; in other embodiments, the first housing 411, the second housing 412, and the third housing 413 are detachably connected by the first snap 4111 structure, which is beneficial for later maintenance or replacement. For example, the first housing 411 and the third housing 413 are connected by the first snap 4111 and the second housing 412 is clamped between the first housing 411 and the third housing 413; or the first housing 411 is connected to the second housing 412 by the first snap 4111, and the second housing 412 is connected to the third housing 413.

[0066] Referring to Figure 4 , Figure 9 and Figure 10 , in some specific embodiments, in the up-down direction, the first housing 411, the second housing 412, and the third housing 413 are arranged in sequence. A plurality of first snaps 4111 are arranged at intervals on the peripheral side of the first housing 411, and a plurality of first snap holes 4131 are arranged at intervals on the peripheral side of the third housing 413. The plurality of first snaps 4111 correspond to the plurality of first snap holes 4131 one by one, and each first snap 4111 is clamped in the corresponding first snap hole 4131 to realize the connection between the first housing 411 and the third housing 413. The second housing 412 is clamped between the first housing 411 and the third housing 413.

[0067] Referring to Figure 4 , Figure 9 and Figure 10 , in some specific embodiments, three first snaps 4111 are respectively arranged on the front side and the rear side of the first housing 411, two first snaps 4111 are arranged on the right side of the first housing 411, three first snap holes 4131 are respectively arranged on the front side and the rear side of the third housing 413, and two first snap holes 4131 are arranged on the right side of the third housing 413.

[0068] Referring to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the framework 42 defines a communication space 421. The top of the communication space 421 is communicated with the first moving space 414 and the second moving space 415, and the bottom of the communication space 421 is communicated with both ends of the transition space 331.

[0069] Both the framework 42 and the guiding component 33 are used to guide the movement of the filter net 2. When the filter net 2 moves from the first moving space 414 to the second moving space 415, it first enters the first end 3311 of the transition space 331 through the communication space 421. After the filter net 2 is cleaned in the transition space 331, it enters the communication space 421 through the second end 3312 of the transition space 331, and finally enters the second moving space 415.

[0070] Refer to Figure 4 、 Figure 5 and Figure 6 In some embodiments, the guiding component 33 extends into the cleaning tank 3121, and the guiding component 33 is provided with a plurality of hollowed-out 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 hollowed-out areas 332 to clean the filter net 2 in the transition space 331.

[0071] In some specific embodiments, the plurality of hollowed-out areas 332 are arranged at intervals along the width direction of the filter net 2.

[0072] Through the above technical solution, each part in the width direction of the filter net 2 has a better cleaning effect.

[0073] In addition to the technical solution of arranging the hollowed-out 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 to enter the transition space 331 to clean the filter net 2.

[0074] Refer to Figure 4 、 Figure 5 and Figure 6 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.

[0075] Refer to Figure 4 、 Figure 5 and Figure 6 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 the 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.

[0076] Refer to Figure 4 、 Figure 5 and Figure 6 In some embodiments, the front, back, left, and right of the top of the framework 42 are all connected to the frame part 41 to ensure the stability of the connection between the framework 42 and the frame part 41.

[0077] Refer to Figure 4 、 Figure 5 and Figure 6, in some specific embodiments, the left side of the first frame body 411 protrudes from the third frame body 413 for connecting to the skeleton 42, and the left side of the top of the skeleton 42 is connected to the left side of the first frame body 411 by screws. Refer to Figure 5 , a limiting groove 422 is provided on the right side of the top of the skeleton 42, and a limiting protrusion 4132 is provided on the left side of the third frame body 413. The limiting protrusion 4132 is clamped in the limiting groove 422 so that the right side of the top of the skeleton 42 is connected to the third frame body 413.

[0078] Refer to Figure 3 , Figure 4 and Figure 5 , second buckles 423 are provided on the right, front and rear sides of the top of the skeleton 42, second positioning holes 4112 are provided on the front and rear sides of the first frame body 411, and second positioning holes 4112 are also provided on the left side of the third frame body 413. The second buckles 423 are clamped in the second positioning holes 4112 to enhance the connection stability among the skeleton 42, the first frame body 411 and the third frame body 413.

[0079] In some embodiments, the skeleton 42 and the guiding assembly 33 are integrally formed parts, which reduces the process of connecting the skeleton 42 and the guiding assembly 33 and lowers the cost of the air conditioner indoor unit 100.

[0080] Refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the air conditioner indoor unit 100 further includes a first driving device 5, and the first driving device 5 is used to cooperate with the filter net 2 to drive the filter net 2 to move.

[0081] By providing the first 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, which improves the automation performance of the air conditioner indoor unit 100.

[0082] Refer to Figure 4 , Figure 5 and Figure 6 , in some embodiments, the first driving device 5 is installed on the skeleton 42. The first driving device 5 includes a driving gear 51 located in the communication space 421, and the filter net 2 includes a transmission part 21. The driving gear 51 meshes with the transmission part 21 to be adapted to drive the filter net 2 to move.

[0083] Through the above technical solutions, 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.

[0084] 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.

[0085] When the filter net 2 is in the first moving space 414, a part of the filter net 2 extends into the first part 4211 to mesh and cooperate with the driving gear 51.

[0086] When the air conditioner indoor unit 100 cleans the filter net 2, the first 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 inside of the cleaning housing 31. The cleaning module 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 meshes with the driving gear 51 again, improving the stability of the driving gear 51 driving the filter net 2 to move. Finally, the filter net 2 in the second part 4212 enters the second moving space 415 under the drive of the driving gear 51. When the filter net 2 is in the second moving space 415, a part of the filter net 2 is in the second part 4212 and meshes 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.

[0087] Referring to Figure 4 、 Figure 5 and Figure 8 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 part 21. The first driving device 5 is correspondingly provided with two driving gears 51, and the two driving gears 51 are distributed at both ends in the width direction of the filter net 2. Each driving gear 51 meshes and cooperates with the corresponding transmission part 21.

[0088] In the above technical solution, the transmission part 21 is engaging teeth extending along the length direction of the filter net 2, which improves the stability of the meshing and cooperation between the transmission part 21 and the driving gear 51, and the transmission parts 21 cooperating with the driving gear 51 are provided at both ends in the width direction of the filter net 2. When the first 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.

[0089] Referring to Figure 4 、 Figure 5 and Figure 7, in some embodiments, the thickness of the filter net 2 is A, and the thickness of the meshing 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.

[0090] Through 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.

[0091] In some specific embodiments, the thickness of the filter net 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.

[0092] 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 meshing 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.

[0093] Refer to Figure 4 、 Figure 5 and Figure 8 , in some embodiments, the first driving device 5 further includes a transmission shaft 52 that rotates synchronously with the driving gear 51, and the two driving gears 51 are respectively installed at both ends of the transmission shaft 52. A plurality of protrusions are circumferentially spaced on the outer peripheral wall of the transmission shaft 52, and the protrusions are adapted to abut against the filter net 2.

[0094] Through the above technical solution, when the first driving device 5 drives the filter net 2 to move, it is not only driven by the two driving gears 51, but also transmitted through 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 the concentration of stress on the filter net 2 and deformation, and extending the service life of the filter net 2.

[0095] 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 plurality of protrusions on the transmission shaft 52 correspond to the plurality of teeth on the driving gear 51 one by one, and each tooth is located in the extending direction of the corresponding protrusion.

[0096] 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 screen 2 and reducing the risk of deformation of the filter screen 2; each tooth is located in the extending direction of the corresponding protrusion, so that the directions of the forces received by the various parts of the filter screen 2 in the width direction are the same, further reducing the risk of deformation of the filter screen 2.

[0097] Referring to Figure 4 , Figure 5 and Figure 8 , 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.

[0098] 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 fast, and improves the assembly efficiency of the air conditioner indoor unit 100.

[0099] 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.

[0100] In some embodiments, the first 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.

[0101] A third transmission gear 56 is provided on the transmission shaft 52 outside the skeleton 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 driving gear 51 on the transmission shaft 52 to rotate.

[0102] In the embodiment of the present invention, the first motor 53 is disposed outside the skeleton 42, avoiding the first motor 53 occupying the space inside the skeleton 42, which is beneficial to the miniaturization of the skeleton 42.

[0103] In some specific embodiments, the first motor 53 is installed on the mounting bracket 4 by screws. A shielding cover 57 is further 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.

[0104] In the above technical solution, the shielding cover 57 shields the first transmission gear 54, the second transmission gear 55, and the third transmission gear 56, preventing external objects from interfering with the transmission gears and affecting the transmission, thereby improving the stability of the first driving device 5.

[0105] In some embodiments, the air conditioner indoor unit 100 includes a first cleaning module 3 and a second cleaning mode. The first cleaning mode is that the vibration device 32 stops operating and the first driving device 5 drives the filter net 2 to reciprocate through the condensed water to clean the filter net 2; the second cleaning mode is that the vibration device 32 operates to clean the part of the filter net 2 located in the condensed water by vibrating the condensed water.

[0106] Through the above technical solution, the air conditioner indoor unit 100 can clean the filter net 2 in two different ways, effectively ensuring the cleaning effect of the filter net 2.

[0107] In some embodiments, in the second cleaning mode, while the cleaning module 3 vibrates the condensed water, the first driving device 5 drives the filter net 2 to reciprocate to clean the filter net 2, further improving the cleaning effect of the cleaning module 3.

[0108] Refer to Figure 4 、 Figure 5 and Figure 6 In some embodiments, a water receiving tray for receiving condensed water is provided inside the casing 1. The air conditioner indoor unit 100 further includes a water supply assembly 6. The water supply assembly 6 is respectively communicated with the water receiving tray and the cleaning tank 3121, and the water supply assembly 6 is adapted to convey the condensed water in the water receiving tray to the cleaning tank 3121.

[0109] When the air conditioner indoor unit 100 is in the refrigeration state or in the dehumidification state, condensed water condenses on the indoor heat exchanger, and the condensed water drops into the water receiving tray. When the air conditioner indoor unit 100 needs to clean the filter net 2, the water supply assembly 6 conveys the condensed water into the cleaning tank 3121 for cleaning the filter net 2.

[0110] Through the above technical solution, when the air conditioner indoor unit 100 needs to clean the filter net 2, there is no need for the user to perform a water replenishment operation. The air conditioner indoor unit 100 automatically extracts the condensed water in the water receiving tray, improving the automation performance of the air conditioner indoor unit 100. The user can use it more conveniently and quickly, and can make full use of water resources to avoid waste of resources.

[0111] Refer to Figure 4 、 Figure 5 and Figure 6, in some specific embodiments, the cleaning housing 31 includes an outer shell 311 and a cylinder block 312. A second opening is provided at the top of the outer shell 311. The cylinder block 312 is disposed within the outer shell 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 outer shell 311 and the bottom wall of the cylinder block 312.

[0112] The ultrasonic generating device includes a driving plate and a vibrating plate 322. The driving plate is mounted on the bottom wall of the outer shell 311, and the vibrating plate 322 is vacuum-bonded to the bottom wall of the cylinder block 312.

[0113] The edge of the top opening of the cylinder block 312 turns outwards to form a first overlapping portion 3122, and the first overlapping portion 3122 overlaps at the edge of the second opening of the outer shell 311.

[0114] The top of the outer shell 311 is fixedly connected to the bottom of the framework 42 to sandwich the first overlapping portion 3122 between the outer shell 311 and the framework 42, so that the cylinder block 312 is stably mounted within the outer shell 311.

[0115] A guiding assembly 33 extending into the cleaning tank 3121 is integrally formed at the bottom of the framework 42.

[0116] Referring to Figure 4 、 Figure 5 and Figure 6 , in some specific embodiments, the water supply assembly 6 includes a first water pump 61. Both ends of the first water pump 61 are respectively communicated with the water receiving tray and the cleaning tank 3121. When the first water pump 61 operates, the condensed water in the water receiving tray is pumped into the cleaning tank 3121.

[0117] In the above technical solution, the condensed water is directly pumped into the cleaning tank 3121 by the first water pump 61, with high conveying efficiency, easy implementation, and reduced cost of the air conditioner indoor unit 100.

[0118] In some specific embodiments, the first water pump 61 is disposed at the bottom side of the cleaning module 3. The water inlet end of the first water pump 61 extends into the water receiving tray. The water supply assembly 6 further includes: a first pipe body 62. One end of the first pipe body 62 is connected to the water outlet end of the first water pump 61 through a clamp, and the other end of the first pipe body 62 is communicated with the cleaning tank 3121 through a clamp.

[0119] It should be noted that the first pipe body 62 being communicated with the cleaning tank 3121 can be that the first pipe body 62 is directly communicated with the cleaning tank 3121, or the first pipe body 62 is communicated with the framework 42 and thus indirectly communicated with the cleaning tank 3121, or other situations, as long as the condensed water can be conveyed into the cleaning tank 3121.

[0120] Referring to Figure 4 、 Figure 11And Figure 12 In some embodiments, the air conditioner indoor unit 100 includes a drainage assembly 7. A drain port 3131 is provided in the cleaning tank 3121, and the drainage assembly 7 is disposed at the drain port 3131 to open or close the drain port 3131. After the cleaning module 3 finishes cleaning the filter net 2, it is necessary to drain the sewage in the cleaning tank 3121. By opening the drain port 3131 through the drainage assembly 7, the sewage can be directly discharged without the user disassembling the cleaning tank 3121, making the drainage operation of the cleaning module 3 more convenient and fast.

[0121] In some specific embodiments, the drainage assembly 7 includes: a push rod 71 and a seal 72 disposed on the push rod 71. The push rod 71 is movably disposed in the cleaning module 3 such that the seal 72 opens or closes the drain port 3131.

[0122] Driving the push rod 71 to move forward can drive the seal 72 to close the drain port 3131; driving the push rod 71 to move backward can drive the seal 72 to open the drain port 3131.

[0123] Through the above technical solution, the operation of opening and closing the drain port 3131 is more convenient, and the structure of the drainage assembly 7 is simple, reducing the cost of the air conditioner indoor unit 100.

[0124] In some specific embodiments, a clamping groove 711 is provided on the outer peripheral wall of the push rod 71. The seal 72 is sleeved on the push rod 71 and clamped in the clamping groove 711, and the seal 72 and the push rod 71 are in interference fit so that the seal 72 is stably disposed on the push rod 71.

[0125] A third guiding surface 712 is provided at the end of the push rod 71. The push rod 71 is inserted into the seal 72 through the third guiding surface 712, thereby connecting with the seal 72. By providing the third guiding surface 712 at the end of the push rod 71, the assembly efficiency of the push rod 71 and the seal 72 is improved.

[0126] The push rod 71 passes through the drain port 3131, and the seal 72 is disposed at one end of the push rod 71 inside the cleaning tank 3121. Moving the push rod 71 downward can drive the seal 72 to close the drain port 3131, and moving the push rod 71 upward can drive the seal 72 to open the drain port 3131. By disposing the seal 72 inside the cleaning tank 3121, when there is condensed water in the cleaning tank 3121, under the pressure of the condensed water, the sealing performance of the seal 72 closing the drain port 3131 is enhanced.

[0127] At the edge of the drain port 3131, an annular abutting portion 3132 extending towards the inside of the cleaning tank 3121 is provided. The cross-section of the seal 72 gradually narrows in the direction towards the drain port 3131, so that the outer peripheral wall of the seal 72 forms a conical surface. When the push rod 71 moves downward, the conical surface of the seal 72 abuts against the annular abutting portion 3132, further enhancing the sealing effect of the seal 72, reducing the possibility of water leakage during the cleaning process of the cleaning module 3, and ensuring the reliability of the operation of the cleaning module 3.

[0128] In some embodiments, the bottom of the cylinder block 312 is detachably connected with a mounting portion 313, and a drain port 3131 is provided on the mounting portion 313. When assembling the cleaning module 3, first insert the push rod 71 into the drain port 3131 of the mounting portion 313, then sleeved the seal 72 on the push rod 71, and finally install the mounting portion 313 on the cylinder block 312, so as to arrange the seal 72 inside the cleaning tank 3121.

[0129] Through the above technical solutions, the installation difficulty of the seal 72 is reduced, and the assembly efficiency of the cleaning module 3 is improved. And when the drainage assembly 7 fails, the mounting portion 313 can be directly disassembled for inspection and repair without disassembling the cleaning module 3, reducing the maintenance cost of the air conditioner indoor unit 100.

[0130] In some specific embodiments, the mounting portion 313 is threadedly connected to the cylinder block 312, and the connection method is simple and the connection stability is high.

[0131] In some specific embodiments, the drainage assembly 7 includes a second driving device 73, and the second driving device 73 cooperates with the push rod 71 to at least push the push rod 71 to move to open the drain port 3131.

That is to say, the whole process of the air conditioner indoor unit 100 cleaning the filter net 2, including: driving the filter net 2 to move, filling water in the cleaning tank 3121, operating the vibration device 32, draining water from the cleaning tank 3121, etc. are all automated without user operation, improving the practicability of the use of the air conditioner indoor unit 100.

[0133] In some embodiments, the second driving device 73 includes: a second motor 731 and a cam 732, and the cam 732 is arranged on the output shaft of the second motor 731. When the output shaft of the second motor 731 rotates, it drives the cam 732 to rotate. The cam 732 can rotate to abut against the push rod 71, and as the cam 732 continues to rotate, the cam 732 pushes the push rod 71 upward to open the drain port 3131.

[0134] The second driving device 73 in the above technical solution has a simple structure, is convenient for obtaining materials, is convenient for installation, and reduces the cost of the air conditioner indoor unit 100.

[0135] In some embodiments, the drainage assembly 7 further includes a reset member 74. The reset member 74 is connected to the push rod 71, and the reset member 74 has an elastic driving force to drive the push rod 71 to close the drain opening 3131. When the cam 732 rotates to separate from the push rod 71, the reset member 74 pushes the push rod 71 to move to close the drain opening 3131.

[0136] Through the above technical solution, the method of closing the drain opening 3131 is simple, and the cost of the air conditioner indoor unit 100 is reduced.

[0137] In some specific embodiments, the reset member 74 is a spring. The spring is sleeved on the push rod 71 and is located outside the mounting portion 313. The two ends of the spring respectively abut against the mounting portion 313 and the push rod 71, so that the spring has a tendency to push the push rod 71 to move downward. The reset member 74 in the embodiment of the present invention is configured as a spring, which is convenient for obtaining materials and convenient for installation, and further reduces the cost of the air conditioner indoor unit 100.

[0138] In some other embodiments, the second driving device 73 is connected to the push rod 71. The second driving device 73 is used to drive the push rod 71 to move forward to open the drain opening 3131, and the second driving device 73 is also used to drive the push rod 71 to move backward to close the drain opening 3131. In this technical solution, the second driving device 73 drives the push rod 71 to open or close the drain opening 3131, which improves the stability of the operation of opening or closing the drain opening 3131.

[0139] In some embodiments, a part of the outer shell 311 facing the drain opening 3131 is provided with a hollow portion, so that the sewage discharged from the drain opening 3131 can fall onto the water receiving tray, and the sewage can be discharged to the outside of the air conditioner indoor unit 100 through the water outlet of the water receiving tray. In some other embodiments, the air conditioner indoor unit 100 is provided with a drain pipe extending to the outside, the drain opening 3131 is communicated with the drain pipe, and the sewage discharged from the drain opening 3131 can be directly discharged to the outside of the air conditioner indoor unit 100 through the drain pipe. It can also be other situations, as long as the sewage can be discharged from the air conditioner indoor unit 100.
