Problems solved by technology

[0005] But in the above structure disclosed in Japanese Utility Model Laid-Open No. 62-103616, there may occur a problem that the interior space of the vehicle becomes small, where the drain pipe is kicked by the vehicle personnel, and where the assembler installs the wiring harness for the motor poor operability
Therefore, it is usually difficult to provide the above-mentioned discharge pipe in practice

Embodiment Construction

[0042] Hereinafter, preferred embodiments of the present invention will be explained with reference to the accompanying drawings.

[0043] 1 shows a structure from a blower fan part to an evaporator part of a vehicle air conditioning unit 1 according to a first embodiment of the present invention, wherein FIG. 1A is a top view of the internal structure, and FIG. 1B is a side view of the internal structure. Reference numeral 2 denotes a blower fan, which has a fan 3 and sends out air for air conditioning through the scroll member 4 by means of the rotation of the fan 3, and reference numeral 5 denotes a motor for driving the blower fan 2 (more specifically, is the motor housing). An evaporator 7 that performs heat exchange between the air sent from the blower fan 2 and the refrigerant circulating through the evaporator 7 is provided in the air conditioning duct 6 at a position downstream of the blower fan 2 . A drain port 8 for discharging condensed water generated in the evap...

Abstract

The invention discloses vehicle air adjusting system, which has a ventilator blower, used for delivering the air of the air adjustment via a turbination component; an electric machine used for driving the ventilator blower; a cavity chamber formed with the turbination component adjacently, which is provided with a cooling air inlet for the electric motor; an evaporator provided at the downriver of the ventilator blower; and a discharging opening provided at the position near the evaporator and used for discharging the condensed water outside the unit; the discharging route used for discharging the water stored in the turbination component is formed as the internal component penetrating the discharging opening of the cavity chamber from the through hole provided on the warm component; sufficient discharging route of the ventilator blower component can be formed by the internal space of the air adjusting unit.

Description

technical field [0001] The present invention relates to a vehicle air conditioning unit, and in particular to an improved drainage structure for its blower component. Background technique [0002] Generally in a vehicle air conditioning unit, a blower fan for sucking in and sending out air for air conditioning is provided at the most upstream position of the air conditioning unit, and the air sent from the blower fan is passed through an evaporator provided at a downstream position It is cooled by heat exchange with the refrigerant, or heated by a heating center provided at a downstream position. The blower fan is driven by a motor, and sends the air introduced from the outside air intake port or the inside air intake port to the downstream side. A scroll-type fan is usually used as such a blower. [0003] In such a blower fan in an air conditioning unit of a vehicle, water or moisture sometimes enters it from the outside air intake port, and if the water that has entered ...
