Abstract

A washer fluid heating device includes a container that contains a washer fluid, a lid portion attached to a first end of the container to face an accommodation space for the washer fluid, heating means that has a proximal end portion attached to the lid portion and extends toward the accommodation space, and an outflow pipe having an outlet disposed in the accommodation space to allow the washer fluid in the accommodation space to flow out, and the outlet of the outflow pipe is provided such that a space formed between a horizontal plane passing through the outlet and an inner wall surface at a second end on an opposite side to the first end of the container corresponds to 10% or more of a volume of the accommodation space.

Claims

1. A washer fluid heating device comprising:

a container that contains a washer fluid;

a lid portion attached to a first end of the container in a direction of a central axis line to face an accommodation space for the washer fluid;

heating means that has a proximal end portion attached to the lid portion and extends toward the accommodation space; and

an outflow pipe having an outlet disposed in the accommodation space to allow the washer fluid in the accommodation space to flow out,

wherein the outlet of the outflow pipe is disposed at a position at which a space formed between a horizontal plane passing through the outlet and an inner wall surface at a second end on an opposite side to the first end of the container corresponds to 10% or more of a volume of the accommodation space.

2. The washer fluid heating device according to claim 1, wherein a heat insulating property of the lid portion is lower than a heat insulating property of the container.

3. The washer fluid heating device according to claim 1, wherein the outflow pipe is fixed by a fixing member attached to a distal end portion of the heating means.

4. The washer fluid heating device according to claim 1, further comprising

an inflow pipe having an inlet disposed in the accommodation space to allow the washer fluid to flow into the accommodation space.

5. The washer fluid heating device according to claim 4, wherein a current plate inclined with respect to the central axis line is disposed between the inlet and the outlet such that the washer fluid from the inlet spirally flows from a side of the first end to a side of the second end inside the container.

6. The washer fluid heating device according to claim 1, wherein the outlet is located between a distal end surface of the heating means and the second end of the container.

7. The washer fluid heating device according to claim 1, wherein the outlet is disposed to overlap the central axis line of the container.
