Referring to fig. 1, an embodiment of an indoor unit of an air conditioner of the present invention includes a casing 100, a heat exchanger (not shown in the figure), and a fresh air device 300. The space that is used for installing heat exchanger and new trend device 300 is equipped with in casing 100, and heat exchanger and new trend device 300 are located in casing 100 respectively, and the left end of heat exchanger edge plate 200 is equipped with along left right direction, and new trend device 300 is installed in the one end of heat exchanger edge plate 200, and it can be understood that new trend device 300 can fixed mounting in casing 100, also can fixed mounting on heat exchanger edge plate 200, no longer specifically prescribes a limit herein. It should be noted that the fresh air device 300 can introduce outdoor fresh air into the room to ensure the freshness of the indoor ambient air and reduce the concentration of indoor carbon dioxide.
Referring to fig. 2 and 4, the fresh air device 300 includes a first scroll 310 and a second scroll 320, the first scroll 310 and the second scroll 320 are arranged in a left-right direction, the first scroll 310 is located on the left side, and the second scroll 320 is located on the right side of the first scroll 310 and on the left side of the heat exchanger.

The first wind wheel 311 is arranged in the first spiral case 310, the second wind wheel 321 is arranged in the second spiral case 320, and the axis of the first wind wheel 311 and the axis of the second wind wheel 321 are arranged in a staggered manner, that is, the first wind wheel 311 and the second wind wheel 321 are arranged on different axes, for example, the axis of the first wind wheel 311 and the axis of the second wind wheel 321 are parallel to each other and do not coincide with each other. The first wind wheel 311 and the second wind wheel 321 are driven independently from each other, so that the second volute 320 can be arranged in an offset manner relative to the first volute 310, and the installation space of the fresh air device 300 can be effectively utilized relative to the coaxial arrangement manner of the first wind wheel 311 and the second wind wheel 321.
Specifically, the inside of the casing 100 of the indoor unit of an air conditioner of the present embodiment has a local interference position, which is at the lower left of the heat exchanger side plate 200, so that the second scroll 320 can be shifted upward relative to the first scroll 310, and thus the lower position of the second scroll 320 is used for forming the avoidance space 400, and thus the space above the avoidance space 400 can be fully utilized to design the second scroll 320 with the maximized size, so that the diameter of the second wind wheel 321 is maximized; when the size of the whole air conditioner indoor unit is fixed, the inside of the casing 100 has enough space 400, and the second volute 320 is offset from the first volute 310, so that the size is maximized, the diameter of the second wind wheel 321 is maximized, the air output of the second volute 320 is increased, and the total air output of the fresh air device 300 is increased. It can be understood that, if the first wind wheel 311 and the second wind wheel 321 are coaxially disposed, the second volute 320 can only be reduced in size in order to construct a sufficient avoidance space 400, so as to reduce the diameter and the blade height of the second wind wheel 321, so that the air output of the second volute 320 is reduced, and the total air output of the fresh air device 300 is reduced.
