Claims

[Scope of Claim for Utility Model Registration] A dash panel provided to partition an automobile engine room and a passenger compartment, a sound-absorbing sheet provided on the passenger compartment side of the dash panel, and an air conditioner that supplies air from inside and outside to an automobile air conditioner. an inside/outside air switching box provided on the passenger compartment side to introduce air into the vehicle;
an outside air inlet opened in the inside/outside air switching box to introduce outside air; an inside air inlet opened in the inside/outside air switching box to introduce inside air; A tamper is rotatably provided inside the inside/outside air switching box so as to be opened/closed, and a connection port located downstream of the damper and open to the inside/outside air switching box; A scroll casing connected to an inside/outside air switching box, a fan housed inside the scroll casing sink, and driving this fan so as to blow the air introduced into the scroll casing from the connection port to a downstream part. a motor attached to the scroll casing, a sound absorption box provided so as to protrude from the inside air suction port and open toward the sound absorption sheet, and a sound absorption material provided on an inner wall of the sound absorption box. An automotive air conditioner characterized by:
