Abstract:
1. A fluid heating assembly for providing a heated cleaning fluid to a vehicle surface comprising: a) a housing extending in a first direction defining two interior chambers spaced from each other in a second direction perpendicular to the first direction in a side-by-side configuration by a separating wall extending in the first direction, said housing including an inlet port in fluid communication with one of said interior chambers defining a first chamber for receiving and heating fluid from an external source; said housing further defining an outlet port in fluid communication with the one of said interior chambers for dispensing an amount of heated fluid to a nozzle for spraying heated fluid onto a surface wherein the separating wall comprises a removable cover which at least partially bounds the first chamber and separates said interior chambers, preventing fluid from leaking out of the first chamber into a second chamber of said interior chambers containing electronics; b) a heating element disposed in the first chamber for heating fluid that passes from the inlet port to the outlet port through the first chamber; c) a heat exchanger supported by said housing in a position that is at least partially covered by fluid within the first chamber and coupled to said heating element so that heat emitting surfaces of said heating element engage and transmit heat to said heat exchanger; and d) a control circuit supported by a printed circuit board within the second chamber for energizing said heating element with a voltage and thereby heat fluid passing from the inlet port to the outlet port through the first chamber.
