The air conditioner indoor unit 100 is installed in an indoor space. The air conditioner outdoor unit 200 is installed in an outdoor space for heat exchange with an outdoor environment.

[0098] The air conditioner indoor unit 100 includes a main body, the main body has a bottom and a top, the main body bottom to the main body top is the height direction of the main body, the main body also has a width direction, wherein one side of the main body in the left-right direction to the other side thereof is the width direction of the main body. The main body has a front side and a rear side that are arranged oppositely, wherein the side of the main body facing the user is the front side of the main body, and the front side of the main body to the rear side of the main body is the front-back direction of the main body.

[0099] The main body may include a housing 11 , which is disposed in the indoor space. The housing 11 has a front side and a rear side that are opposite to each other, wherein a side of the housing 11 facing the user is the front side of the housing 11 .

[0100] The main body may include a heat exchange air inlet 111, and the heat exchange air inlet 111 is disposed on the top of the housing 11. During cooling or heating, indoor air may enter the interior of the housing 11 through the heat exchange air inlet 111.

[0101] The main body may include a first cavity, which is disposed inside the housing 11 . The first cavity is communicated with the heat exchange air inlet 111 , and indoor air may enter the first cavity through the heat exchange air inlet 111 .

[0102] The main body may include a heat exchange outlet 112, which is disposed at the bottom of the housing 11, and the first cavity is respectively connected to the heat exchange inlet 111 and the heat exchange outlet 112. When cooling or heating, indoor air flows into the first cavity through the heat exchange inlet 111 and flows into the room through the heat exchange outlet 112.

[0103] The main body may include an indoor heat exchanger 1001, which is disposed in the first cavity. The indoor heat exchanger 1001 is used to exchange heat with indoor air entering the first cavity.

[0104] In some embodiments, the main body may include a heat exchange fan, which is disposed in the first cavity. The fan may be used to drive the indoor air into the first cavity through the heat exchange air inlet 111, and then flow through the indoor heat exchanger 1001, and then flow into the room through the heat exchange air outlet 112. It may be arranged that the fan is disposed on the leeward side of the indoor heat exchanger 1001 to reduce the resistance of the indoor heat exchanger 1001 to the air flow and increase the air intake into the room.

[0105] The blower may include a motor and a fan. The drive shaft of the motor is connected to the fan. The fan is driven by the motor to rotate to drive the air in the first chamber to flow.

[0106] In some embodiments, the air conditioner outdoor unit 200 is disposed in an outdoor space, and the air conditioner outdoor unit 200 includes a second cavity disposed in a housing, and an outdoor air inlet and an outdoor air outlet are disposed on the housing. The outdoor air inlet is connected to the outdoor space and the second cavity, and the outdoor air outlet is connected to the outdoor space and the second cavity.

[0107] In some embodiments, an outdoor heat exchanger 202 is disposed in the shell, and refrigerant flows in the outdoor heat exchanger 202 . The refrigerant in the outdoor heat exchanger 202 can be used to exchange heat with the air entering the second cavity and flowing through the outdoor heat exchanger 202 .

[0108] In some embodiments, a compressor 201 is disposed in the shell, the compressor 201 is disposed in the second chamber, and the compressor 201 is installed at the bottom of the air-conditioning outdoor unit 200 .

[0109] In some embodiments, the air-conditioning outdoor unit 200 may include a throttling device 204, which is disposed in the second cavity and is used to expand the liquid refrigerant in a high-temperature and high-pressure state into a low-pressure liquid refrigerant. The throttling device 204 may be disposed on the leeward side of the outdoor heat exchanger 202, and may be conveniently connected to the compressor 201.

[0110] The air conditioner 1000 performs a refrigeration cycle of the air conditioner 1000 by using the compressor 201, the outdoor heat exchanger 202, the throttling device 204 and the indoor heat exchanger 1001. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0111] The compressor 201 compresses the low-temperature and low-pressure refrigerant gas and discharges the high-temperature and high-pressure refrigerant gas. The discharged refrigerant gas flows into the outdoor heat exchanger 202 .

[0112] The outdoor heat exchanger 202 condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0113] The throttling device 204 expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the outdoor heat exchanger 202 into a low-pressure liquid-phase refrigerant.

[0114] The indoor heat exchanger 1001 evaporates the refrigerant expanded in the throttling device 204 and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor 201 .

[0115] The indoor heat exchanger 1001 can achieve a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner 1000 can adjust the temperature of the indoor space.

[0116] In both the indoor heat exchanger 1001 and the outdoor heat exchanger 202, one is a condenser and the other is an evaporator. When the indoor heat exchanger 1001 is used as a condenser and the outdoor heat exchanger 202 is used as an evaporator, the air conditioner 1000 is used as a heater in the heating mode. When the indoor heat exchanger 1001 is used as an evaporator and the outdoor heat exchanger 202 is used as a condenser, the air conditioner 1000 is used as a cooler in the cooling mode.

[0117] refer to Figure 4-Figure 14 In some embodiments, the main body may further include a cleaning module 12 , which is disposed corresponding to the heat exchange air inlet 111 , and is used to clean dust on the filter 321 .

[0118] In some embodiments, the cleaning module 12 may include a filter 321 , which is disposed corresponding to the heat exchange air inlet 111 , and has a first end and a second end disposed opposite to each other. Air may flow through the heat exchange air inlet 111 and the filter 321 , and flow out through the heat exchange air outlet 112 .

[0119] In some embodiments, the filter screen 321 is configured as a single-layer sheet filter screen 321. The single-layer sheet filter screen 321 has a small wind resistance, which can solve the problem of large air volume loss caused by using a double-layer filter screen 321, thereby reducing air volume loss.

[0120] In some embodiments, the cleaning module 12 may include a first roller 322, which is connected to the first end of the filter 321. The first roller 322 is fixedly connected to the first end of the filter 321, and the filter 321 can be rolled up on the first roller 322 by rotating the first roller 322 forward, and the filter 321 rolled up outside the first roller 322 can be detached from the first roller 322 by rotating the first roller 322 backward.

[0121] In some embodiments, the cleaning module 12 may include a second roller 323, which is connected to the second end of the filter 321.

[0122] In some embodiments, when the first roller 322 rotates forward, the second roller 323 rotates forward. When the first roller 322 rotates reversely, the second roller 323 rotates reversely.

[0123] In some embodiments, the cleaning module 12 may include a first gear 3221 . The first gear 3221 is disposed at the axial end of the first roller 322 . The first gear 3221 is connected to the first roller 322 . The first gear 3221 and the first roller 322 rotate synchronously.

[0124] In some embodiments, the cleaning module 12 may include a second gear 3231 . The second gear 3231 is disposed at the axial end of the second roller 323 . The second gear 3231 is connected to the second roller 323 . The second gear 3231 and the second roller 323 rotate synchronously.

[0125] In some embodiments, the cleaning module 12 may include a third gear 3203 , the third gear 3203 is connected to the first gear 3221 , the third gear 3203 and the first gear 3221 are coaxially arranged, and the third gear 3203 and the first gear 3221 rotate synchronously.

[0126] In some embodiments, the cleaning module 12 may include a first cleaning brush 327, which is disposed below the filter 321. The first cleaning brush 327 can be rotatably connected to the cleaning module 12, and at least a portion of the first cleaning brush 327 can be in contact with the filter 321, so that when the first roller 322 rolls up the filter 321, the filter 321 and the first cleaning brush 327 generate sliding friction, and the first cleaning brush 327 can clean the filter 321 to brush off the dust on the filter 321.

[0127] In some embodiments, the cleaning module 12 includes a first driving assembly 3201 , which is transmission-connected to the first roller 322 and the second roller 323 , and the first driving assembly 3201 can drive the first roller 322 and the second roller 323 to rotate.

[0128] In some embodiments, the first driving assembly 3201 may include a first motor 32011 , the first motor 32011 having a first output shaft, and the first motor 32011 may drive the first output shaft to rotate.

[0129] In some embodiments, the first driving assembly 3201 may include a first motor gear 32012 , which is fixedly connected to the first output shaft. The first output shaft can drive the first motor gear 32012 to rotate, and the first motor gear 32012 is externally meshed with the first gear 3221 for transmission.

[0130] In some embodiments, the first drive assembly 3201 may include a toothed belt 32013 which is arranged in a ring shape and has teeth on its inner ring. The toothed belt 32013 is meshed with the third gear 3203 and the toothed belt 32013 is meshed with the second gear 3231 .

[0131] The first motor 32011 drives the first output shaft to rotate to drive the first motor gear 32012 to rotate, and the first motor gear 32012 drives the first gear 3221 to rotate, and the first gear 3221 and the third gear 3203 rotate synchronously to allow part of the filter 321 to be rolled up on the first roller 322. The third gear 3203 drives the toothed belt 32013 to rotate, and the toothed belt 32013 drives the second gear 3231 and the second roller 323 to rotate so that part of the filter 321 is separated from the second roller 323.

[0132] The cleaning module 12 is disposed corresponding to the heat exchange air inlet 111, which will not increase the size of the housing 11 in the front-to-back direction and has little effect on the appearance of the air conditioner 1000, making the appearance of the machine appear thin and not bulky.

[0133] The third gear 3203 and the second gear 3231 are synchronously driven by the toothed belt 32013, so that there is no need to separately set up motors to drive the first roller 322 and the second roller 323, thereby saving the driving mechanism, reducing costs, and saving the setting of transmission gears, making the transmission of the filter 321 smoother, reducing the thickness of the driving mechanism, and increasing the air inlet area.

[0134] In some embodiments, when the first gear 3221 rotates forward, the third gear 3203 rotates forward synchronously, the third gear 3203 drives the toothed belt 32013 to rotate, and the toothed belt 32013 drives the second gear 3231 to rotate forward, so that when the first roller 322 rotates forward, the second roller 323 rotates forward.

[0135] In some embodiments, when the first gear 3221 rotates in the opposite direction, the third gear 3203 rotates in the opposite direction synchronously, the third gear 3203 drives the toothed belt 32013 to rotate, and the toothed belt 32013 drives the second gear 3231 to rotate in the opposite direction, so that when the roller rotates in the opposite direction, the second roller 323 rotates in the opposite direction.

[0136] In some embodiments, the rotation direction of the first roller 322 can be changed by adding a second driven gear between the first motor gear 32012 and the first gear 3221. By adding a second driven gear, the first roller 322 and the first motor gear 32012 can rotate in the same direction or in opposite directions at the same time.

[0137] In some embodiments, the cleaning module 12 does not include the third gear 3203, the toothed belt 32013 is internally meshed with the first motor gear 32012 for transmission, the toothed belt 32013 is internally meshed with the first gear 3221 for transmission, the toothed belt 32013 is internally meshed with the second gear 3231 for transmission, and the first motor gear 32012, the first gear 3221 and the second gear 3231 are all arranged inside the toothed belt 32013.

[0138] The first motor 32011 drives the first output shaft to drive the first motor gear 32012 to rotate forwardly. The forward rotation of the first motor gear 32012 drives the toothed belt 32013 to rotate forwardly. The toothed belt 32013 drives the first gear 3221 and the second gear 3231 to rotate forwardly so that part of the filter screen 321 is rolled up on the first roller 322.

[0139] The first motor 32011 drives the first output shaft to drive the first motor gear 32012 to rotate in the opposite direction.
