Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2013/099182
Kind Code:
A1
Abstract:
An impeller (51) is surrounded in a case (20) by inner wall surfaces (S) located on the outside of the impeller (51) in the radial direction. The inner wall surfaces (S) include first inner wall surfaces (S1) and second inner wall surfaces (S2). Heat exchangers (15) are present between the impeller (51) and the first inner wall surfaces (S1). The heat exchangers (15) are not present between the impeller (51) and the second inner wall surfaces (S2). The distance between the impeller (51) and the second inner wall surfaces (S2) is less than the distance between the impeller (51) and the first inner wall surfaces (S1). An air flow guide section (90) has an outer peripheral surface (91). The outer peripheral surface (91) extends along the rotational direction of the impeller (51) at a position between a back plate (26) and a hub (53) and between a motor (49) and at least the second inner wall surfaces (S2). The outer peripheral surface (91) is tilted or curved so that the distance between the outer peripheral surface (91) and a rotation axis (A) decreases toward a front plate (25) in the direction of the rotation axis (A).
