Abstract

(57) [Summary] [Purpose] To provide an injection port structure of a washer tank having a simple structure capable of easily injecting a washer liquid. [Composition] A communication hole 9 for communicating the inside and outside of the washer tank 3 is formed in the cap 8, and a sub cap for opening and closing the communication hole 9 is detachably provided on one surface side of the cap 8 and communicated with the other surface side of the cap 8. A cylindrical member 13 is provided which communicates with the hole 9 and has a tip portion 13a having a larger diameter than a base end portion 13b. When the cap 8 is attached to the inlet 5 of the washer tank 3 so that the tubular member 13 is outside the washer tank 3, the tip portion 13a of the tubular member 13 is the inlet of the washer tank 3 by the length of the tubular member 13. Since it is located above 5, it is easy to inject the washer fluid. The diameter of the distal end portion 13a of the tubular member 13 of the cap 8 is larger than that of the proximal end portion 13b, and the washer liquid can be easily injected by this amount.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inlet structure for a washer tank used in an automobile.

[0002]

2. Description of the Related Art An example of mounting a conventional washer tank is shown in FIG. In the figure, a washer tank 3 for storing washer liquid is arranged in an engine room 2 of an automobile 1. The washer tank 3 is provided with an injection cylinder 4 extending upward, and the height of the injection port 5 is set to be substantially the same as the height of the fender 6. A cap 7 is openably and closably attached to the injection port 5. In the washer tank 3, when supplying or replenishing washer liquid or water (hereinafter referred to as washer liquid), the cap 7 is removed, the inlet 5 is opened, and the washer liquid is injected from the inlet 5.

In addition, as another conventional technique, the actual fair 2-35.
There is a cleaning water tank device disclosed in Japanese Patent No. 617. In this device, a water receiver made of an elastic material is provided in a hose communicating with the washer tank, and the water receiver has a diameter larger than that of the inlet when pulled out from the inlet.

[0004]

By the way, in the above-mentioned washer tank 3 of FIG. 4, since the height of the inlet 5 is set to be substantially equal to the height of the fender 6, when the washer liquid is injected, the fender is filled. 6 was an obstacle and it was difficult to work. Further, in the conventional technique disclosed in the above publication, when the water receiver is pulled out from the inlet 5, it is easily bent and the workability is deteriorated.
Further, in order to prevent bending, another member must be prepared, and the device may be complicated by that amount.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a washer tank injection port structure having a simple structure capable of easily injecting a washer liquid.

[0006]

In order to achieve the above object, the present invention provides a cap, which covers an inlet of a washer tank for storing washer liquid, with a communication hole for communicating the inside and outside of the washer tank, A sub-cap that opens and closes the communication hole is detachably provided on one surface side of the cap, and a tubular member that communicates with the communication hole on the other surface side of the cap and has a tip end side having a larger diameter than a base end side. It is characterized by being provided.

[0007]

With the above construction, when the washer tank is filled with liquid, if the cap is attached to the inlet of the washer tank so that the tubular member is outside the washer tank, the tip end side of the tubular member is longer than the tubular member. It will be located just above the inlet of the washer tank.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An inlet structure for a washer tank according to an embodiment of the present invention will be described below with reference to FIGS. In the figure, a cap 8 is put on the injection port 5 of the injection cylinder 4 of the washer tank 3. The cap 8 has an annular disc 10 having a communication hole 9 formed in the center thereof.
And the ring portion 1 formed on the peripheral side of the annular disc 10.
1, an annular projection 12 formed on one surface side of the annular disc 10 so as to go around the communication hole 9, and a tubular member 13 formed on the other surface side of the annular disc 10 in communication with the communication hole 9. It is roughly composed of.

The tubular member 13 has its inner diameter dimension (outer diameter dimension) gradually increased from the base end side (upper side in FIG. 1) toward the tip end side (lower side in FIG. 1), and the tip end portion 13a is at the base end portion. It has a larger diameter than 13b. A sub cap 14 is detachably attached to the annular projection 12. By attaching the sub cap 14, the communication hole 9 is closed.

The ring portion 11 extends to the one surface side and the other surface side of the annular disc 10, and the first and the first portions projecting inwardly (toward the center of the annular disc 10) at the ends of the extension side thereof. Two flanges 15 and 16 are formed. First and second flange 1
5 and 16 are fitted to an injection cylinder flange 17 formed at the end (injection port 5) of the injection cylinder 4 so as to project outward, whereby the cap 8 is held by the injection cylinder 4. ing.

In the injection port structure of the washer tank constructed as described above, the cylinder member 13 is positioned in the injection cylinder 4,
The second flange 16 is fitted on the injection cylinder flange 17 and the cap 8 is put on the injection port 5 (FIGS. 1 and 2). And
The sub cap 14 is fitted on the annular protrusion 12 and the communication hole 9 is closed by the sub cap 14. In this state,
The washer liquid is contained in the washer tank 3 so as not to leak outside.

When the washer liquid in the washer tank 3 is reduced to a predetermined level, the cap 8 is separated from the injection cylinder 4 and the sub cap 14 is attached to the annular projection 12.
And cap 8 upside down (cylindrical member 13
The first flange 15 is fitted to the injection cylinder flange 17 so that the outside of the washer tank 3 is covered), and the cap 8 is covered on the injection cylinder 4 (FIGS. 3 and 4). In this state,
The tip portion 13a is the injection port 5 of the injection cylinder 4 and thus the fender 6
In comparison with the above, the position is higher by the length of the tubular member 13. Therefore, the fender 6 does not hinder the work at the time of injection, and the washer liquid can be easily poured. Temporarily use a bottle to wash the internal washer fluid.
Even when injecting into the bottle, it becomes possible to inject without contacting the fender 6 with the bottle, and it is easy to inject. Further, the tip end portion 13a of the tubular member 13 has a larger diameter than the base end portion 13b, and the washer fluid can be injected more easily by this amount.

As shown in FIG. 5, the tubular member 13 is formed of a light transmitting member, and a plurality of grooves 18 or protrusions 19 are formed in the tubular member 13 in the longitudinal direction so that the washer liquid remains. It can be used to confirm the amount. In this case, if the tubular member 13 is formed long, the remaining amount can be confirmed over a wide range.

[0014]

Since the present invention has the inlet structure of the washer tank configured as described above, when the cap is attached to the inlet of the washer tank so that the tubular member is outside the washer tank, the tubular member is Since the tip end side of the is located above the inlet of the washer tank by the length of the tubular member, it becomes easier to inject water. Also,
The tip side of the tubular member of the cap has a larger diameter than that of the base side, and the washer fluid can be injected more easily by this amount.
