Abstract

A vehicle air dryer for removing water from a vehicle as the vehicle emerges from a car wash includes a plenum, a source of pressurized air, a slot nozzle, and a screen. The plenum extends a length, has an annular wall, and defines an interior cavity to hold air. The plenum also defines inlet and outlet ports communicating with the interior cavity. The source of pressurized air is in fluid communication with the inlet port of the plenum. The slot nozzle has an outlet in fluid communication with the outlet port, an inlet spaced from the outlet and in fluid communication with the interior cavity, and an interior passageway extending between the outlet and the inlet. The screen can be disposed between the inlet of the slot nozzle and the interior cavity.

Dependent claims

A vehicle air dryer comprising:

a plenum extending a height along a vertical axis between bottom and top ends and having an annular wall extending about said vertical axis, said plenum defining an interior cavity and configured to hold air at a pressure greater than atmospheric pressure, said plenum also defining inlet and outlet ports communicating with said interior cavity;
a source of pressurized air in fluid communication with said inlet port of said plenum;
a slot nozzle having an outlet in fluid communication with said outlet port, an inlet spaced from said outlet and in fluid communication with said interior cavity, and an interior passageway extending between said outlet and said inlet;
said slot nozzle disposed in said interior cavity and dividing said interior cavity into a primary chamber and a secondary chamber, said secondary chamber and said primary chamber extending along said vertical axis and said primary chamber being coextensive with said secondary chamber;
