Abstract:
1. Apparatus for providing a heated cleaning fluid to a vehicle surface comprising: a) an inlet port for receiving an amount of fluid; b) a reservoir in fluid communication with the inlet port for heating fluid which enters a reservoir interior from the inlet port comprising a reservoir portion contacted by fluid within the interior constructed of a first thermoplastic material that expands if the fluid within the reservoir freezes to prevent damage to the reservoir; and a second reservoir portion or portions also contacted by fluid within the interior constructed of a second material different from the first thermoplastic material, said reservoir including an internal passageway which divides fluid entering the reservoir into separate flow paths for heating prior to exiting the reservoir; c) an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid; d) a heating element for heating fluid that passes from the inlet to the outlet; and e) a control circuit for energizing at least a portion of the heating element with a voltage to heat the heating element and the fluid passing from the inlet to the outlet.
