1. Apparatus for providing a heated cleaning fluid to a vehicle surface comprising:
- a) an inlet port for receiving an amount of fluid;
b) an outlet port in fluid communication with the reservoir for dispensing an amount of heated fluid;
c) a metal heater coil having an interior passageway for heating fluid that passes from the inlet to the outlet port through said passageway;
wherein the heater coil is covered, at least in part by an elastic material for containing fluid in the event of a ruptured heating element caused by one or more freeze/thaw expansion and contraction cycles; and
d) a control circuit for energizing at least a portion of the metal heating coil with a voltage to heat the heating element and the fluid passing from the inlet to the outlet.

Abstract
Apparatus and method for providing a heated cleaning fluid to a vehicle surface. The apparatus has an inlet port for receiving an amount of fluid; an outlet port for dispensing an amount of heated fluid; a heating element coil or tube covered with a plastic sheath that heats up fluid passing from the inlet to the outlet; and a control circuit for energizing at least a portion of the heating element with a voltage to heat the fluid passing from the inlet to the outlet. The apparatus also has expandable and compressible features and parts for protection against freezing.

20. A method for providing a heated cleaning fluid to a vehicle surface comprising:
-
a) coupling an electrically conductive fluid carrying tube to a source of cleaning fluid; b) routing a cleaning fluid into an inlet port of the tube such that the fluid flows from the inlet to an outlet port of said tube; c) energizing said tube with a voltage to heat the fluid carrying tube and the fluid passing through the tube; d) directing the fluid from the outlet port to a nozzle for dispensing heated fluid against said surface; and e) covering at least a portion of the fluid carrying tube with an elastic material to contain fluid in the event of a ruptured tube caused by one or more freeze/thaw expansion and contraction cycles. - View Dependent Claims (21, 22, 23)

31. A method for providing a heated cleaning fluid to a vehicle surface comprising:
-
a) covering an electrically conductive heating element with a flexible plastic tube having an elongated length sufficient to heat fluid passing through the flexible plastic tube; b) routing a cleaning fluid into an inlet port of the plastic tube such that the fluid flows from the inlet to an outlet port of said tube; c) energizing the heating element to heat the fluid passing through the tube; d) directing the fluid from the outlet port of the tube to a nozzle for dispensing heated fluid against said surface. - View Dependent Claims (32, 33)

34. A method for providing a heated cleaning fluid to a vehicle surface comprising:
-
a) coupling a source of cleaning fluid to a heating vessel; b) routing a cleaning fluid into an inlet of the heating vessel such that the fluid flows from the inlet to an outlet of said vessel; c) heating fluid in the heating vessel as it passes from the inlet to the outlet; d) directing the fluid from the outlet to a nozzle for dispensing heated fluid against said vehicle surface; and e) activating a motor in response to the user activating a switch to dispense heated fluid from a nozzle and provide wiping action of wipers. - View Dependent Claims (35, 36, 37, 38, 39)
