Title:
AIR CONDITIONING DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/079924
Kind Code:
A1
Abstract:
This air conditioning device for a vehicle supplies air to a side vent opening part regardless of the discharge mode and allows the discharge of air from a defrost opening part during a discharge mode in which the ratio of air blown to a passage leading to a foot opening part is at maximum, wherein any change in the amount of air supplied from the defrost opening part is minimized by a simple structure that does not require fine adjustment, even if the downstream-side air passage of the side vent opening part has been closed. [Solution] A passage (third passage 23) leads to a side vent opening part 17b downstream of heat exchangers 6, 7 when a rotary-type first door 25, which adjusts the air-blowing ratio between a first passage 21 leading to a foot opening part 18 and a second passage 22 leading to a defrost opening part 16 and a center vent opening part 17a, is in the position of a discharge mode in which the ratio of air blown to the first passage 21 is at maximum, and the third passage 23 is configured from a passage that connects a side upstream of a first door 25 and a side vent opening part 17b regardless of the discharge mode.
