Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2013/080395
Kind Code:
A1
Abstract:
In order to provide an air conditioner with which it is possible to prevent the reverse flow of indoor air from indoors and through the discharge port into the interior of the air conditioner at both ends in the lengthwise direction of the discharge port of an indoor unit of the air conditioner, and with which it is possible to prevent an increase in energy loss, thereby reducing power consumption and reducing noise, the construction is such that the length of a crossflow fan (8) in the direction (AX) of the axis of rotation is greater than the lengthwise length of the discharge port (3), and the crossflow fan (8) has fan extensions (8a) that extend outward in the direction (AX) of the axis of rotation from both ends of the discharge port (3). Furthermore, the main body of the indoor unit is equipped with a collision wall (18) with which the flow of air discharged from the fan extensions (8a) collides. Furthermore, an opposing surface (18a) of the collision wall (18) is constructed such that, in a cross section perpendicular to the axis of rotation (17), the distance Mb between the rear-guide-side end part (19b) of the opposing surface (18a) and the outer circumferential part (8b) of the fan is greater than the distance Ma between the stabilizer-side end part (19a) of the opposing surface (18a) and the outer circumferential part (8b) of the fan.
