So, air-inlet grille 120a is formed with air inlet 120h to realize indoor apparatus of air conditioner 10 side air admission along circular arc direction.
In the present embodiment, heat exchanger 126 is arc, and heat exchanger 126 is arranged at the inner side of air-inlet grille 120a and covers air inlet 120h.
So, the shape of heat exchanger 126 closes the air entering housing 120 from air inlet 120h is carried out heat exchange with the matching form of air-inlet grille 120a.
In the present embodiment, indoor apparatus of air conditioner 10 is disposed with current collector 122g, stator blade element 122h and diffusion cone 122i along air supply direction.
So, indoor apparatus of air conditioner 10 is disposed with current collector 122g, stator blade element 122h and diffusion cone 122i so that the air-flow in air channel is carried out supercharging along air supply direction.
In the present embodiment, stator blade element 122h includes annular inside casing 122k, surrounds the ring frame 122l of annular inside casing 122k and connect multiple stator blade 122m of annular inside casing 122k and ring frame 122l, current collector 122g docks with ring frame 122l, and diffusion cone 122i docks with annular inside casing 122k.
So, the air-flow flowing through air channel is carried out supercharging by stator blade element 122h.
In the present embodiment, diagonal flow fan 124 includes oblique flow wind wheel 124a and for driving the motor 124b of oblique flow wind wheel 124a, and oblique flow wind wheel 124a includes round table-like wheel hub 124c and the fan blade 124d extended radially outwards from the outer peripheral face of wheel hub 124c.
So, oblique flow wind wheel 124a drives the air through heat exchanger 126 heat exchange to enter air channel.
In the present embodiment, being formed with the first gas channel 122q, fan blade 124d and be located in the first gas channel 122q between current collector 122g and wheel hub 124c, the first gas channel 122q changes along air supply direction convergent.
So, the sectional area of the first gas channel 122q tapers into along air supply direction, thus improving the air-flow wind speed through the first gas channel 122q.
