Abstract: A dual-layer flow blower unit for a vehicle air-conditioner is disclosed. The blower unit has a scroll shape so as to be blown to each of a pair of an upper blower duct and a lower blower duct, and includes a pair of an upper blower case and a lower blower case which are vertically partitioned by a partition plate. The blower unit comprises a drainage case coupled to a lower part of the lower blower case and having a drainage duct formed so as to incline downward along a longitudinal direction of the lower blower duct. The blower unit includes a blower motor cooling unit that cools a blower motor by branching a part of an air blown from the lower blower duct, flowing it into an inside of a cooling chamber, and then circulating it inside a motor case.

Abstract: A first case member of a blower unit has a first communication passage communicating with an air intake side of a blower. A second case member of a temperature adjustment unit has a second communication passage communicating with a condensed water discharge portion through which condensed water is discharged. The respective case members are joined with each other in a state where a portion forming the first communication passage and a portion forming the second communication passage face each other. The portion of the first communication passage includes a drain portion having a groove shape and configured to discharge water in the first communicating passage. The portion of the second communication passage includes a drain receiving portion having a groove shape, communicating with the first communication passage and receiving the water discharged from the drain portion.

Abstract: A vehicle air conditioner includes an air-conditioning case having a drain hole through which an air passage communicates with an outside of a vehicle compartment, a heat exchanger disposed inside the air passage, and a seal member. The seal member is held between a dash panel and a seal wall of the air-conditioning case. The seal member has a through hole, and closes a through hole of the dash panel. The vehicle air conditioner includes a refrigerant pipe and a pressure reducing valve. The first case part and the second case part are fitted with each other in a fitting part below which, in the vertical direction, the air-conditioning case has a communication hole through which an outside of the air-conditioning case communicates with the air passage.
