[0042] Specifically, the air conditioner indoor unit in this embodiment further includes a volute tongue 60, which is arranged in the indoor unit housing 10. The first cleaning brush 30 and the second cleaning brush 50 can be arranged on the volute tongue 60. With such a setting, since the volute tongue 60 is arranged relative to the fan blade 20, by arranging the first cleaning brush 30 and the second cleaning brush 50 on the volute tongue 60, it is convenient to clean the fan blade 20 by the first cleaning brush 30 and the second cleaning brush 50, so as to improve the cleaning effect. Specifically, the first cleaning brush 30 has a first avoidance position and a first cleaning position, and the second cleaning brush 50 has a second avoidance position and a second cleaning position. When the first cleaning brush 30 is in the first avoidance position, the first cleaning brush 30 avoids the air outlet 100, and the first cleaning brush 30 can be located at the bottom of the volute tongue 60 (or at the horizontal position of the upper end of the air outlet 100) or fit with at least part of the volute tongue 60, so that the effect of affecting the air outlet of the first cleaning brush 30 can be avoided. When the first cleaning brush 30 is in the first cleaning position, the first cleaning brush 30 rotates to a position in contact with the fan blade 20 to clean the fan blade 20. When the second cleaning brush 50 is in the second avoidance position, the second cleaning brush 50 avoids the air outlet 100, and the second cleaning brush 50 can be located at the bottom of the volute tongue 60 (or at a horizontal position at the upper end of the air outlet 100) or fit with at least part of the volute tongue 60, so that the second cleaning brush 50 can be avoided from affecting the air outlet effect. When the second cleaning brush 50 is in the second cleaning position, the second cleaning brush 50 rotates to a position in contact with the fan blade 20 to clean the fan blade 20.

[0043] Specifically, the indoor unit of the air conditioner further includes a volute 70, which is arranged in the indoor unit housing 10, or the first cleaning brush 30 and the second cleaning brush 50 can be arranged on the volute 70, and specifically, the first cleaning brush 30 and the second cleaning brush 50 are arranged opposite to the fan blade 20. With such an arrangement, it is convenient to clean the fan blade 20 by the first cleaning brush 30 and the second cleaning brush 50 to improve the cleaning effect. Specifically, the first cleaning brush 30 has a first avoidance position and a first cleaning position, and the second cleaning brush 50 has a second avoidance position and a second cleaning position. When the first cleaning brush 30 is in the first avoidance position, the first cleaning brush 30 avoids the air duct arrangement, and the first cleaning brush 30 can fit with the volute 70, so that the effect of the first cleaning brush 30 affecting the air outlet can be avoided. When the first cleaning brush 30 is in the first cleaning position, the first cleaning brush 30 rotates to a position in contact with the fan blade 20 to clean the fan blade 20. When the second cleaning brush 50 is in the second avoidance position, the second cleaning brush 50 avoids the air duct setting, and the second cleaning brush 50 can fit with the volute 70, so that the effect of the second cleaning brush 50 affecting the air outlet can be avoided. When the second cleaning brush 50 is in the second cleaning position, the second cleaning brush 50 rotates to a position in contact with the fan blade 20 to clean the fan blade 20. When the first cleaning brush 30 and the second cleaning brush 50 are both located on the volute 70, the rotation angle between the first cleaning brush 30 and the first cleaning position is small, and the rotation angle between the second cleaning brush 50 and the second cleaning position is small, so that it is easy to control so that there is no interference movement between the first cleaning brush 30 and the second cleaning brush 50. At the same time, since the first cleaning brush 30 and the second cleaning brush 50 cannot be seen from the outside, it is more beautiful, so there is no need to set the guide part 40 for shielding, which simplifies the internal structure. Since the rotation angle of the first cleaning brush 30 and the second cleaning brush 50 is relatively small here, it is preferred that a driving structure is connected to the same end of the first brush handle 32 and the second brush handle 52, and the rotation direction of the first brush handle 32 is opposite to or the same as the rotation direction of the second brush handle 52. In this way, when the first cleaning brush 30 and the second cleaning brush 50 move, the contact movement friction at different positions in the width direction of the first cleaning brush 30 facilitates the removal of dust at the position on the fan blade 20 corresponding to the brush width, and removes dust retained on the first cleaning brush 30 and the second cleaning brush 50.

[0044] In this embodiment, the indoor unit of the air conditioner further includes a nozzle 80, which is disposed in the indoor unit housing 10 and is disposed toward the fan blades 20, so that the water sprayed by the nozzle 80 cleans the fan blades 20. Specifically, the nozzle 80 is disposed on the volute 70, and the nozzle of the nozzle 80 is disposed toward the fan blades 20. With such a configuration, while the first cleaning brush 30 and the second cleaning brush 50 clean the fan blades 20, the water sprayed by the nozzle 80 also cleans the fan blades 20, so that the cleaning effect on the fan blades 20 can be further improved, so as to better improve the quality of the air after heat exchange, so as to better improve the comfort.

[0045] Specifically, the indoor unit of the air conditioner in this embodiment further includes an evaporator assembly 90 and a water receiving tray. The evaporator assembly 90 is arranged in the indoor unit housing 10, and at least part of the evaporator assembly 90 is located above the fan blade 20. The water receiving tray is arranged at the bottom of the evaporator assembly 90 so that the condensed water on the evaporator assembly 90 flows into the water receiving tray. With such a structural arrangement, it is possible to prevent the condensed water from being directly retained in the indoor unit housing 10 and flowing out from the air outlet 100, and at the same time, the condensed water can be collected and utilized. Specifically, the evaporator assembly 90 in this embodiment is located in the upper half of the fan blade 20.

[0046] In this embodiment, the water receiving tray is connected to the nozzle 80 so that the condensed water collected in the water receiving tray is sprayed out through the nozzle 80 to effectively utilize the condensed water. At the same time, with such a setting, there is no need to provide an additional water source, which simplifies the device. Specifically, when cleaning the fan blade 20, the first cleaning brush 30 and the second cleaning brush 50 are driven to clean the fan blade 20, and the nozzle 80 sprays water on the fan blade 20. The cleaning and water spraying actions can be controlled to be performed simultaneously or alternately, so as to realize the automatic cleaning of the fan blade 20 by the air conditioner indoor unit in the running state. Specifically, the nozzle 80 can also be rotatably arranged so that the nozzle 80 rotates to a position opposite to the fan blade 20 and a position opposite to the first cleaning brush 30 and the second cleaning brush 50. When the nozzle 80 rotates to a position opposite to the first cleaning brush 30 and the second cleaning brush 50, it is convenient to clean the fan blade 20 through the nozzle 80 to clean the dust on the first cleaning brush 30 and the second cleaning brush 50.

[0047] Specifically, the nozzle 80 can be arranged below the fan blade 20, and the nozzle 80 is close to the lower end surface of the air outlet 100.
