Abstract

A washer fluid heating device includes: a cover portion attached to one end of a container to face an accommodation space of a washer fluid; heating means that includes a case having a proximal end portion attached to the cover portion and extending toward the accommodation space, and a heating unit provided inside the case to heat the washer fluid inside the accommodation space through the case; and a detector for detecting a no-water burning state generated due to a decrease in washer fluid inside the accommodation space. The detector is provided inside the case and disposed on a side of the proximal end portion of the case from the healing unit.

First claim

The invention claimed is:

1. A washer fluid heating device comprising:
a container that accommodates a washer fluid;
a cover portion attached to a bottom end of the container to face an accommodation space of the washer fluid;
a heater structure that includes a case having a proximal end portion attached to the cover portion and extending in a vertical direction from the bottom end of the container towards a top end of the container, and a heater located inside the case to heat the washer fluid inside the accommodation space through the case; and
a temperature detector configured to detect a no-water burning state generated due to a decrease in washer fluid inside the accommodation space,
wherein the heater is separated from the cover portion in the vertical direction, and
the temperature detector is provided inside of the heater structure and positioned within the case at a position located below a lower end of the heater.

2. The washer fluid heating device according to claim 1 , wherein the temperature detector is located at or above the cover portion in the vertical direction.

3. The washer fluid heating device according to claim 2 , wherein the temperature detector is buried in a filling portion filled with a filler inside the case.

4. The washer fluid heating device according to claim 3 , wherein a material contained in the filler includes a silicone-based adhesive.

5. The washer fluid heating device according to claim 1 , wherein the temperature detector is buried in a filling portion filled with a filler inside the case.

6. The washer fluid heating device according to claim 5 , wherein a material contained in the filler includes a silicone-based adhesive.

7. The washer fluid heating device according to claim 5 , wherein a material contained in the filler includes an epoxy-based adhesive.

8. The washer fluid heating device according to claim 5 , wherein a material contained in the filler includes at least one of a silicone-based resin, modified silicone-based resin and urethane-based resin without adhesive action.

9. The washer fluid heating device according to claim 1 , wherein the temperature detector includes a thermal fuse or a thermal switch.

10. The washer fluid heating device according to claim 1 , further comprising:
a heating adjustment structure configured to adjust heating of the heater structure.

11. The washer fluid heating device according to claim 1 , further comprising:
an outflow pipe located in the accommodation space to allow the washer fluid in the accommodation space to flow out,
wherein a distal end of the outflow pipe is inclined with respect to the vertical direction.

12. The washer fluid heating device according to claim 1 , further comprising:
an outflow pipe located in the accommodation space to allow the washer fluid in the accommodation space to flow out,
wherein a distal end of the outflow pipe comprises a notch.

13. The washer fluid heating device according to claim 1 , wherein a material contained in the case includes at least one of heat-resistant resin, ceramics and metal.

14. The washer fluid heating device according to claim 1 , wherein a temperature of the no-water burning state is in a range of about 80° C. to 90° C., when a material contained in the cover portion includes resin.

15. The washer fluid heating device according to claim 1 , wherein an internal space of the case comprises a heating space that accommodates the heater in the vertical direction, and
the heating space is filled with a heat-resisting filler.

16. The washer fluid heating device according to claim 15 , wherein a material contained in the heat-resisting filler includes magnesium oxide.

17. The washer fluid heating device according to claim 1 , wherein the temperature detector is buried in a filling portion filled with a filler inside the case,
an internal space of the case comprises a heating space that accommodates the heater in the vertical direction,
the heating space is filled with a heat-resisting filler, and
the heat-resisting filler and the filling portion are connected in the vertical direction.

18. The washer fluid heating device according to claim 1 , wherein the heater includes an electric heating wire.

19. The washer fluid heating device according to claim 1 , wherein the heater includes a heat exchanging system using a waste heat generated in an engine of a vehicle.
