Abstract
A vehicle air-conditioning unit includes an air-conditioning case and an inside/outside air switching door that is configured to change a ratio of a flow rate of an inside air to a flow rate of an outside air in an air introduced into the air-conditioning case. The vehicle air-conditioning unit includes a cooler that is disposed in the air-conditioning case, and a blower that is located downstream of the cooler and sends the air to a vehicle compartment. The air-conditioning case includes a drain pipe located downstream of the cooler, the drain pipe having a tube shape through which a condensed water generated on the cooler is drained out of the air-conditioning case. The cooler is located on an extended line of a centerline of the drain pipe such that a suction air drawn through the drain pipe into the air-conditioning case flows along the cooler.
