ABSTRACT:
A defrost diffuser in the dash plate of a motor vehicle includes an inlet sleeve for receiving conditioned air and includes laterally spaced outlet slots for distributing the air upwardly toward and laterally across the windshield of the vehicle. A center outlet slot is in vertical registry with the inlet sleeve and is located between two outboard slots. Relatively large volume pods are spaced from opposite sides of the sleeve and communicate therewith by way of restricted channels. The pods define static regain chambers to reduce the velocity effect of the airflow toward the outboard outlet slots and to promote a more even distribution of the airflow from the center slot and the outboard slots. For economy of manufacture, the diffuser is made as an integral one-piece molded plastic unit.
