Claims

[Scope of Claim for Utility Model Registration] In an intake unit for a vehicle air conditioner, which has an intake door that selectively switches between an inside air intake port and an outside air intake port, and a blower that sucks selected air selected by the intake door. , the intake door is formed in a triangular prism shape,
It has a support axis spanning the vertices of both sides forming an isosceles triangle, and two surfaces including this support axis,
It has two surfaces perpendicular to the support shaft and an outer surface facing the support shaft, and the support shaft is disposed near the suction port of the blower, and the intake door is extended into the blower suction port using the support shaft as a fulcrum. A filter is provided on one side of the intake door including the support shaft on the blower suction port side of the intake door, and a filter is provided on one side of the intake door that faces the outer surface of the intake door and that allows inside air to flow in and out of the intake door. An inlet and an outside air inlet are arranged side by side, and an opening is provided on the side opposite to the filter on the outer surface of the intake door, and when the intake door enters the blower inlet, the opening is one of the inside air or outside air inlets. While communicating with the inlet on the filter side, when the intake door is out of the blower suction port, the outer surface closes the inlet on the filter side among the inside air or outside air inlets, and the opening is connected to both inlets. An intake unit for a vehicle air conditioner, characterized in that the intake unit communicates with an inlet on the opposite side of the filter.
