AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2021/172714
Kind Code:
A1
Abstract:
The present invention relates to an air guide for guiding air to a cross-flow fan of an air conditioner and, more specifically, to an air conditioner comprising a front panel and a rear panel, wherein: the front panel includes a case having an intake grill, the cross-flow fan disposed inside the case, and a heat exchanger; the rear panel has the air guide; the air guide includes a first guide surface inclined toward the cross-flow fan, and a second guide surface positioned at the downstream side of the first guide surface; and the first guide surface has a distribution guider for distributing and guiding air, and thus the air having been equally distributed by means of the distribution guider is suctioned into the cross-flow fan so that vortex generation is prevented, thereby enabling noise to be reduced.
