Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a window wash liquid container for use in cold regions that is attached to a vehicle.

[Conventional example]

BACKGROUND OF THE INVENTION During operation of a vehicle, dust in the air or sand thrown up in the air adheres to a windshield attached to a vehicle. In addition, in cold regions, snow may accumulate on the windshield, and moisture may freeze and stick to the windshield.

The above-mentioned dust, sand, ice chips, etc. deteriorate visibility through the windshield and impede safe driving of the vehicle. So there was dust on the windshield,
If sand, snow or ice flakes are present,
Operate the wiper to remove dirt.

However, if there is dust or sand on the windshield and the windshield is dry, the dirt will stick to the windshield and it will be difficult to remove it sufficiently even if the wipers are operated. It is. Further, if snow or ice chips are frozen and stuck to the windshield, it is difficult to remove them with a wiper unless some of the snow or ice pieces are thawed.

Therefore, windshield fluid is usually sprayed onto the windshield to moisten the dust and sand or melt some of the snow and ice chips to make them easier to remove.

Incidentally, this window washer fluid is stored in a window washer container installed inside the vehicle, pressurized by a pump, and then jetted out from a nozzle.

[Problem that the invention attempts to solve]

In the above-mentioned window washer fluid container, the temperature of the window washer fluid is equal to the outside temperature. If the outside temperature is higher than the freezing point of the window washer fluid, there is no problem in using the above-mentioned window washer fluid container, but if you live in a cold region and the outside temperature drops significantly, there are various Problems arise.

The first is freezing of the window wash fluid. If the outside temperature drops below the freezing point of the window washer fluid, the window washer fluid will freeze in the container, making it impossible to use the window washer device. Furthermore, even if the window washer fluid does not freeze in the container, the window washer fluid that has been cooled to near the freezing point will freeze at the point where it passes from the container through the pressure pump to the jet nozzle, causing the device to freeze. may become unusable.

As mentioned above, if the window washer device becomes inoperable, it will not be able to sufficiently remove dust, sand, snow, ice chips, etc. from the windshield, which will pose a danger to vehicle operation.

Further, once the window washer fluid is frozen, it must be heated from the outside by some method in order to thaw it, making it difficult to thaw it.

Second, when removing snow or ice flakes from a windshield in cold regions, even if you use windshield fluid that has been cooled to near the freezing point, it has little effect on melting the snow or ice flakes. There's a problem.

[Means to solve problems]

A recess is formed on the outer surface side of the hollow heating container, and an inner container into which the window washer liquid is injected is housed in the recess, and the heating container is placed in the heating container. A warm air inlet and an exhaust outlet are provided to communicate the interior space of the heater with the outside.

[Effect]

In this invention, when hot air is introduced from the hot air inlet, the window washer fluid is heated.

〔Example〕

1 and 2 show an embodiment of this invention.

In these figures, reference numeral 1 denotes a rectangular parallelepiped window wash liquid container (inner container), and the upper end of this container 1 is formed with a cylindrical opening 3 in which a screw 2 is formed. A plug 4 is fastened to this opening 3. Further, at the lower part of the two facing sides of the container part 1, the container part 1
Tubes 5, 5 which lead out the window washer liquid inside are connected, and these tubes 5, 5 are fixed without slack by tube bands 6, 6 at the upper ends of the respective connected sides.

The above container part 1 is a box-shaped cover (heating container) 7
It is contained within. This cover 7 has an outer wall 9 in the shape of a hollow rectangular parallelepiped that is sufficiently larger than the container part 1, and an inner wall 8 that is depressed from the outer wall 9 toward the inside of the cover 7. A space having a generally concave cross section is formed. On the other hand, the space defined on the outer surface side of the inner wall 8 is
The recess 10 is formed into a rectangular parallelepiped shape that is slightly larger than the container 1, and accommodates the container 1. Grooves 11, 11 are formed on the two inner side surfaces of the inner wall 8 to accommodate the tubes 5, 5.
Tubes 5, 5 extend outward along these grooves 11, 11.

The two facing sides of the outer wall 9 have an opening 1 that communicates the space inside the cover 7 with the outside.
2 and 13 are formed. A cylindrical hot air blowing section 14 is attached to the opening 12, and the hot air blowing section 14 is connected to the air conditioner 1 of the vehicle.
Warm air is supplied from No. 5. Further, the other opening 13 has a cylindrical exhaust part 16.
is installed.

Next, the operation of the window wash container having the above structure will be explained.

When a vehicle is operated in a cold region, if the temperature drops below the freezing point of the windshield fluid, the windshield fluid can be expected to freeze. Further, when snow or ice flakes adhere to the windshield, if the window washer fluid is at a low temperature, it is less effective in melting the snow or ice flakes.

In the above case, the air conditioner 15 of the vehicle is activated and hot air is introduced from the hot air blower 14.
The introduced warm air flows into the space inside the cover 7. The warm air that has flowed in in this manner spreads in all directions in the space and exchanges heat with the cover 7 and the container 1, which are cooler than the air.

On the other hand, the air that was previously in the space is sequentially exhausted from the exhaust section 16 along with the inflow of warm air. The hot air blowing unit 14 and the exhaust unit 16 are attached to the lower right end and the upper right end of the two side faces facing each other, so the warm air that flows in is evenly distributed to every corner of the space, and the other side The air cooled by heat exchange with the cover 7 and the container part 1 is quickly exhausted from the exhaust part 16 without any stagnation.

As a result, the bottom and side surfaces of the container part 1 are heated evenly, and therefore the window washer liquid stored inside the container part 1 is efficiently heated.

In this way, the window wash fluid that has been cooled to near the outside temperature is warmed and stored, and will not freeze in the container even if the outside temperature drops further. Furthermore, when the window washer device is operated, the warmed window washer liquid spreads throughout the device, and in order to warm the inside of the device, it also flows from the container through the pump to the nozzle. , the window washer fluid is prevented from freezing.

Furthermore, if there are snow or ice flakes on the windshield, the snow or ice flakes can be removed by spraying heated window wash fluid from this window wash container. can be effectively melted and removed easily.

Furthermore, since the recess 10 is provided in the cover 7 to house the container 1, the container 1 and the internal space of the cover 7 are separated by the inner wall 8, and as a result, the container 1 is damaged and liquid leaks. There is also no risk of window wash fluid entering the vehicle's air conditioning piping system. Therefore, there is no risk of window washer fluid entering and damaging the air conditioning equipment, and when repairing or inspecting the container section 1, there is no need to repair or inspect the air conditioning piping system, which greatly reduces work time. .

Incidentally, if the container part 1 is simply housed inside the cover 7 by simply providing an opening in the outer wall 9 of the cover 7, the window washer liquid will enter the inside of the cover 7 at the same time as the container part 1 is damaged, and furthermore. Since the air flows backward from the hot air blowing section 14 to the air conditioner side, there is a risk of some damage to the air conditioner.
Since repairs are also required, an increase in man-hours is unavoidable.

[Effect of idea]

In this invention, a recess is formed on the outer surface of the hollow heating container, and the inner container into which the window washer liquid is injected is housed in the recess, and the inner container into which the window washing liquid is injected is housed in the recess. Since a hot air inlet and an exhaust port are provided to communicate the internal space of the heating container with the outside, it is possible to heat the window washer container by introducing hot air from the hot air inlet. Therefore, it is possible to effectively prevent the window wash fluid from freezing in cold regions.

Further, in this invention, since the windshield washer fluid is heated, snow and ice chips on the windshield can be quickly melted when the window washer is used.

Furthermore, according to the present invention, even if the inner container into which the window washer fluid is injected is damaged, the window washer fluid will not enter the vehicle's air conditioning piping system, so the air conditioning equipment will be damaged due to damage to the inner container. Furthermore, there is no need to repair or inspect the air conditioning piping system when repairing the inner container, so the work time is significantly reduced.
