Title:
VEHICULAR AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/249857
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the performance of an aspirator. A vehicular air conditioning device (1) comprises: a case body; an evaporator (20); a heater core (40); and an aspirator (50) for guiding air in a vehicle cabin to a temperature detection unit. The case body integrally comprises a case upstream unit (12) in which the evaporator (20) and the heater core (40) are stored, and a case downstream unit (13) in which the air circulated through the case upstream unit (12) is circulated. The case upstream unit (12) has a first flow passage (16a) that circulates the air in a Z-axis direction, and a second flow passage (16b) that connects to a downstream side of the first flow passage (16a), and circulates the air in a Y-axis direction. The aspirator (50) has a primary air introducing unit (53), and is mounted at a center portion of the case body. The primary air introducing unit (53) has an inlet (53d) formed at an upstream end, and introduces the air in the case body from the inlet (53d). The upstream end of the primary air introducing unit (53) is connected to the second flow passage (16b) from the Z-axis direction.
