Claims

[Scope of utility model registration request]

The casing of the intake unit is constructed by joining the first case and the second case, and the first case has an inside air circulation port through which the inside of the vehicle interior flows, an outside air inlet through which outside air flows in, and an intake door that switches and controls the inside and outside air. The second case is formed on the inner wall side of the first case in an intake unit for an air conditioner for an automobile having a fan driven by a motor and a bell mouth for guiding incoming air to the fan. A porous metal plate whose edge is inserted into the groove and installed inside the casing of the intake unit, the first case and the bell mouth form a resonance chamber, and the air flow path inside the casing of the intake unit and the bell mouth form a resonance chamber. An intake unit characterized in that the resonance chamber communicates with the resonance chamber through small holes in the porous metal plate.
