Drainage structure for vehicle air-conditioning device

A drainage structure for a vehicle air-conditioning device of a vehicle, the vehicle comprising:

• a partition wall configured to partition between an interior and an exterior of a vehicle cabin for a passenger;
• an evaporator arranged at outside of the partition wall for the vehicle cabin, the evaporator being configured to cool air to be supplied to the interior of the vehicle cabin through heat exchange with a refrigerant;
• and a cover attached to the partition wall from a front side of the vehicle cabin, the cover being configured to accommodate the evaporator,
• the drainage structure comprises a drain pipe for draining condensed water generated by the evaporator to outside by extending in an attachment direction of the cover by being inserted into the cover, wherein
• the drain pipe has:
• a slit formed so as to be inclined upwards along an extending direction from a lower end portion,
• a guide portion configured to guide the condensed water generated by the evaporator to the extending direction;
• and
• a drainage plug attached to a tip end of the guide portion, and the slit being provided on the drainage plug.

• the drain pipe has a slit formed so as to be inclined upwards along an extending direction from a lower end portion,
• the drain pipe is provided so as to be inclined by a first predetermined angle with respect to a horizontal plane so that a tip end portion, at which the slit is provided, is positioned lower than a base end portion, to which the condensed water generated by the evaporator is supplied, and
• the slit is provided so as to be inclined by a second predetermined angle with respect to the horizontal plane, the second predetermined angle being greater than the first predetermined angle.
