The third heat exchange tube group 33 is connected to the second heat exchange tube group 32, and is located below the second heat exchange tube group 32 and behind the cross-flow fan 20. By adjusting the arrangement of the heat exchanger 30 in the indoor unit of the air conditioner in the manner, a space can be reserved between the front of the cross flow fan 20 and the front panel, so that the front of the cross flow fan 20 is not shielded by the heat exchanger 30, and the cross flow fan 20 is convenient to disassemble and clean. In the embodiment of the present disclosure, the orientations of "up, down, front, and back" are defined based on the directions shown in fig. 2.

In the related art, the heat exchanger 30 may also include a first heat exchange tube group 31, a second heat exchange tube group 32, and a third heat exchange tube group 33. The first heat exchange tube set 31 is arranged in front of the cross flow fan 20, the second heat exchange tube set 32 and the third heat exchange tube set 33 are arranged above the cross flow fan 20, and the second heat exchange tube set 32 and the third heat exchange tube set 33 are arranged in an inclined manner and form a certain included angle therebetween. In this way, the heat exchanger 30 completely covers the crossflow fan 20. If the cross flow fan 20 needs to be disassembled or the cross flow fan 20 needs to be cleaned, the heat exchanger 30 with complicated structure and installation needs to be disassembled first, so that the disassembly and cleaning of the cross flow fan 20 are particularly complicated, and the cleaning of the indoor unit of the air conditioner is inconvenient.

Optionally, the volute tongue strip 40 includes an arc-shaped section 41 and an inclined section 42, the cross-sectional shape of the inner side surface of the arc-shaped section 41 is an arc shape protruding toward the front panel side, and the arc-shaped section surrounds the front side of the cross-flow fan 20, and the upper edge of the arc-shaped section 41 is close to the lower part of the first heat exchange tube set 31; the inclined section 42 is inclined, and the inner side surface of the inclined section is planar, and the inclined section 42 is connected with the arc section 41 and is disposed at the lower part of the arc section 41.
