Air conditioner indoor unit 100 according to the ... of the embodiment of the present invention is described below with reference to Fig. 1-Fig. 3.Air conditioner indoor unit 100 can be with
For air-conditioning indoor hanging unit.In the description below the application, said so that air conditioner indoor unit 100 is air-conditioning indoor hanging unit as an example
It is bright.Certainly, it will be understood by those skilled in the art that air conditioner indoor unit 100 can also be applied to other kinds of air conditioner, without
It is limited to air-conditioning indoor hanging unit.
As shown in Figure 1, such as air-conditioning indoor hanging unit of air conditioner indoor unit 100 of embodiment according to a first aspect of the present invention, packet
Include body 1.
Specifically, body 1 has spaced first spiral case and the second spiral case 12, the first spiral case and the second spiral case 12
Between limit exhaust passage 13, the one end (for example, upper end in Fig. 1) in air duct 13 is equipped with wind wheel 14, and the first spiral case includes neighbouring wind
It takes turns the volute tongue of 14 settings and is connected to one end (for example, left end in Fig. 1) of neighbouring second spiral case 12 of volute tongue and is directed away from
The diffuser 113 that the direction of wind wheel 14 extends.
For example, in the example of fig. 1, when air conditioner indoor unit 100 is air-conditioning indoor hanging unit, the top of body 1 has back
There is air outlet 131, wind wheel 14 to be located in body 1 for air port 16 and lower front side, and heat exchanger 15, heat exchanger are equipped in body 1
15 between wind wheel 14 and return air inlet 16, and the first spiral case and the second spiral case 12 are separated from each other and limit in the longitudinal direction
