Problems solved by technology

[0013] However, in the structure in which the drain hole is provided on the air blowing side of the blower, part of the air whose temperature has been adjusted in the heat exchanger flows to the outside of the air conditioner casing through the drain hole, so the ventilation loss increases.

Abstract

The present disclosure provides a vehicular air conditioner unit with which it is possible to inhibit ventilation loss while suppressing the generation of noise during discharging of water. In a vehicular air conditioner unit (10), a space formation part (20) forming a water discharge space (21) partitioned from an air channel (13) is provided to an air conditioner case (12). A water discharge part (24) for discharging water in the air conditioner case to the exterior of the air conditioner case is formed in the space formation part. An upstream-side communication part (26) communicating between the water discharge space and an upstream-side space (131) on the upstream side, with respect to the flow of air, of a blower (18) in the air channel is formed in the space formation part. A downstream-side communication part (27) communicating between the water discharge space and a downstream-side space (132) on the downstream side, with respect to the flow of air, of the blower in the air channel is also formed in the space formation part.

Description

[0001] Cross-reference of related applications [0002] This application is based on Japanese application number 2016-144484 for which it applied on July 22, 2016, and uses the description content here. technical field [0003] The present invention relates to a vehicle air conditioning unit for air conditioning a vehicle interior. Background technique [0004] Conventionally, a vehicle air-conditioning unit of an air mixing system is known to adjust the mixing ratio of air cooled by an evaporator, which is a heat exchanger for cooling, and air heated by a heater core, which is a heat exchanger for heating. Adjusts the temperature of the air blown into the vehicle interior. [0005] For such a vehicle air conditioning unit, there is a vehicle air conditioning unit of a so-called suction type arrangement in which a blower blowing air to the vehicle interior is arranged on the downstream side of the air flow of a heat exchanger such as an evaporator (for example, refer to Pat...
