Abstract

A heated washer fluid assembly for heating washer fluid is provided to clean a windshield of a motor vehicle. The motor vehicle includes an engine and a fluid reservoir. The heated washer fluid assembly includes a first conduit has a receiving end fluidly connected to the fluid reservoir and an opposing delivery end for transferring washer fluid from the fluid reservoir to the delivery end. The first conduit also includes a middle segment disposed between the receiving and delivery ends and abutting a portion of the engine such that washer fluid passing through the middle segment is heated by the heat generated by the engine. The heated washer fluid assembly also includes a blanket covering said middle segment of said first conduit and the portion of the engine for insulating the heated washer fluid in said middle segment of said first conduit.

Claims

1. A heated washer fluid assembly for heating washer fluid to clean a windshield of a motor vehicle having an engine and a fluid reservoir, said heated washer fluid assembly comprising:

a conduit having a receiving end fluidly connected to the fluid reservoir and an opposing delivery end for transferring washer fluid from the fluid reservoir to said delivery end, said conduit including a middle segment disposed between said receiving and delivery ends and abutting a portion of the engine such that washer fluid passing through said middle segment is heated by the heat generated by the engine; and

a blanket covering said middle segment of said conduit and the portion of the engine for insulating the heated washer fluid in said middle segment of said conduit.

2. A heated washer fluid assembly as set forth in claim 1 including a pump assembly coupled to the fluid reservoir for pumping washer fluid from the fluid reservoir into said conduit.

3. A heated washer fluid assembly as set forth in claim 2 wherein said blanket is formed from a heat-absorbent material.

4. A heated washer fluid assembly as set forth in claim 3 wherein said conduit is formed from a heat-resistant material.

5. A heated washer fluid assembly as set forth in claim 4 wherein said washer fluid is heated to a temperature between approximately 130°

F. and 170°

F.

6. A heated washer fluid assembly as set forth in claim 5 including a thermostat fluidly interconnected between said conduit and the windshield for controlling the flow of heated washer fluid thereto.

7. A method for heating washer fluid stored in a fluid reservoir of a motor vehicle including an engine, a conduit coupled to the fluid reservoir and having a middle segment abutting a portion of the engine, and a blanket covering the portion of the engine, the method comprising the steps of:

transferring the washer fluid from the fluid reservoir to the conduit;

heating the washer fluid via heat generated by the engine as the washer fluid passes through the middle segment of the conduit abutting the portion of the engine;

insulating the washer fluid with the blanket as the washer fluid is heated within the middle segment of the conduit; and

conveying the heated washer fluid from the conduit to the windshield.

8. A method as set forth in claim 7 including the step of controlling the flow of the heated washer fluid from the conduit to the windshield.

9. A method as set forth in claim 8 wherein the step of heating the washer fluid via heat generated by the engine as the washer fluid passes through the middle segment of the conduit abutting the portion of the engine includes the step of heating the washer fluid to a temperature between approximately 130°

F. and 170°
