The present invention is a solvent heater for vehicular window washing solvent. The applicant is aware of the following prior art in the field.
Various solvent heating devices and related devices are known in the art. For example, U.S. Pat. No. 5,383,247 entitled, “Washing Installation for Windshields or Motor Vehicles, Aircraft, Locomotives or The Like”, issued to Nickel on Jan. 24, 1995, teaches a cleaning installation for windshields of motor vehicles, aircraft, locomotives or the like with at least one wiper arm drivable by a wiper motor.
In another example, U.S. Pat. No. 7,775,224 entitled, “Windshield De-Icing” issued to Franco et al., on Aug. 17, 2010, teaches an apparatus for cleaning a window of a vehicle, including a vessel, having an inlet through which a washing fluid is received from a reservoir and an outlet through which the fluid is discharged for cleaning the window. There is a heating element for heating the fluid in the vessel, which element preheats the vessel before the washing fluid is received therein, whereby at least an initial quantity of the fluid is rapidly heated and discharged from the vessel.
Another example, U.S. Pat. No. 7,445,165 entitled, “Apparatus and Method for Windshield Cleaning and De-icing”, issued to Franco et al. on Nov. 4, 2008, teaches an apparatus for cleaning a window of a vehicle, including a vessel, having an inlet through which a washing fluid is received from a reservoir and an outlet through which the fluid is discharged for cleaning the window, a heating element for heating the fluid in the vessel, a controller for controlling flow of the fluid through the vessel and an actuator in wireless communication with the controller.
Another example, U.S. Pat. No. 7,171,716 entitled, “Windshield De-icing”, issued to Franco et al., on Feb. 6, 2007, teaches an apparatus for cleaning a window of a vehicle having an inlet through which a washing fluid is received from a reservoir and outlet through which the fluid is discharged for cleaning the window. There is a heating for heating the fluid in the vessel, which element preheats the vessel before the washing fluid is received therein, whereby at least an initial quantity of the fluid is rapidly heated and discharged from the vessel.
Another example, U.S. Pat. No. 6,892,417 entitled, “Windshield De-icing”, issued to Franco et al., on May 17, 2005, teaches an apparatus for cleaning a window of a vehicle having an inlet through which a washing fluid is received from a reservoir and outlet through which the fluid is discharged for cleaning the window. There is a means for heating the fluid in the vessel, which element preheats the vessel before the washing fluid is received therein, whereby at least an initial quantity of the fluid is rapidly heated and discharged from the vessel.
Another example, U.S. Pat. No. 6,669,109 entitled, “Apparatus For Cleaning or De-icing Vehicle Window”, issued to Ivanov et al., on Dec. 30, 2003 teaches an apparatus for cleaning or de-icing a vehicle window, including a reservoir for containing therein a washing fluid, a vessel having an inlet through which the washing fluid is received from the reservoir and an outlet through which the fluid is discharged for cleaning a vehicle window, and a first heating element disposed in the vessel for heating the fluid in the vessel, characterized by an auxiliary heating element being disposed in the vessel for heating the fluid in the vessel, wherein the auxiliary heating element is disposed at a bottom portion of the vessel and is operative to heat a quantity of fluid which is not necessarily sufficient to cover the first heating element.
In one embodiment of the instant invention there is a solvent heater for vehicular window washing solvent. The solvent heater comprises a heat exchanger mounted on a vehicle exhaust pipe surface. The heat exchanger has a high temperature flexible wrap surrounding the heat exchanger and the exhaust pipe. The heat exchanger has at least one restraining device for maintaining the heat exchanger and the flexible wrap to a portion of the vehicular exhaust pipe.
In another embodiment, the instant invention is a solvent heater for vehicular window washing solvent. The solvent heater comprises a heat exchanger mounted on an exhaust pipe surface of a vehicle. The heat exchanger has an inlet end and an outlet end. There is a check valve at a near end of the outlet end. The heat exchanger has a high temperature flexible wrap surrounding the heat exchanger and the exhaust pipe. The heat exchanger has at least one restraining device for maintaining the heat exchanger and the flexible wrap to a portion of the vehicular exhaust pipe.
Yet another embodiment of the instant invention is a solvent heater for vehicular window washing solvent. The solvent heater comprises a heat exchanger mounted on an outside surface of an exhaust pipe of a vehicle in a cured epoxy resin. The heat exchanger has a high temperature flexible wrap surrounding the heat exchanger and the exhaust pipe. The heat exchanger has at least one restraining device for maintaining the heat exchanger and the flexible wrap to a portion of the vehicular exhaust pipe.
There is a first liquid transfer line that has a first end and a second end. The first end is fluidly connected to the pump. The second end is fluidly connected to an inlet port of the heat exchanger. There is a second liquid transfer line that has a first end and a second end. The second liquid transfer line first end is fluidly connected to an outlet port of the heat exchanger. The second liquid transfer line second end is fluidly connected to at least one windshield washer ejection port. There is a check valve in the second liquid transfer line to prevent the liquid from returning to the heat exchanger.
The present invention is a solvent heater wherein the heat exchanger is a ceramic heat exchanger. The present invention is a solvent heater wherein the heat exchanger is a heat resistant rubber hose.
The heat exchanger 4 has a high temperature flexible wrap 10 surrounding the heat exchanger 4 and the exhaust pipe 6. The heat exchanger 4 has at least one restraining device 22 for maintaining the heat exchanger 4 and the flexible wrap 10 to a portion of the vehicular exhaust pipe 6.
There is a first liquid transfer line 44 that has a first end 46 and a second end 48. The first end 46 is fluidly connected to the pump 42. The second end 46 is fluidly connected to an inlet port of the heat exchanger 4. There is a second liquid transfer line 48 that has a first end 50 and a second end 52. The second liquid transfer line 48 first end 50 is fluidly connected to an outlet port of the heat exchanger 4. The second liquid transfer line 48 second end 52 is fluidly connected to at least one windshield washer ejection port 60. There is a check valve 18 in the second liquid transfer line 48 to prevent the liquid from returning to the heat exchanger 4.
