[Problem that the invention attempts to solve]

However, with automatic water supply type window wash tank structure, not only do you need to check the water level frequently depending on the frequency of use, but if you neglect to check the water level and replenish the water, you may not realize that there is no water. Depending on the situation, operating the wipers may completely block your field of vision, which can be extremely dangerous. Furthermore, in order to use a washer solution containing detergent, it is necessary to purchase detergent solution every time the washer solution runs out, which is troublesome and tends to increase costs.

In addition, regarding the rainwater replenishment device for automobiles disclosed in the above-mentioned Japanese Utility Model Publication No. 60-34074,
Although the water level is detected electrically, if the water level reaches the vicinity of the sensor, the water level may be detected due to the posture or vibration of the vehicle while it is running, even though it is full of water.
Situations may occur where the water surface is shaking and the sensor does not detect it, causing the sensor to blink repeatedly.

For example, even with highly viscous liquids such as fuel, the fuel warning may sometimes flash repeatedly. If the washing fluid is not used and there are no rainy days in this state, the switching valve will continue to be electrically switched, resulting in wasted power. Further, since the tank only contains water, detergent must be injected in order to use it as a washer fluid, which is troublesome and goes against the idea of maintenance-free design.

Furthermore, the filter is installed inside the body, making it troublesome to replace the filter. Rainwater is used as it is as cooling water, and acid rain is corrosive and fine dust cannot be removed, making it undesirable as engine cooling water. On the other hand, there is no problem in practical use with washer fluid unless it is contaminated with large particles that would clog the pipes. As mentioned above, there are various problems with the rainwater replenishment device for automobiles.

Furthermore, the detergent dripping device for car window cleaning disclosed in the above-mentioned Japanese Utility Model Publication No. 57-176358 is not equipped with any valve mechanism, and the washer fluid flows out when it is raining. There is no need for a detergent dripping device for window cleaning. Furthermore, when the windshield is dirty, such as on a sunny day, when the windshield is dirty, that is, when the washer fluid is needed, an extremely irrational situation occurs in which the washer fluid does not flow out. As mentioned above, there are various problems with the above detergent dripping device for cleaning automobile windows.

Therefore, the purpose of this invention is to solve the above problems. Rainwater and water from car washing are automatically stored in a wash tank and used as wash water, and a filter is used to purify the water. To provide a window washer tank structure characterized in that a cartridge containing a solid detergent for making a detergent-containing washer liquid is installed in a water passage.

A wire mesh 2 is installed as a filter. Also,
The washer tank 5 is provided with a water inlet 11.

FIG. 1 shows the main parts of the window wash tank structure according to this invention. This window washer tank structure mainly consists of a funnel 3, a neck 20 and a washer tank 5.
The funnel 3 is connected to the rain gutter 1, and the funnel 3 and the water tank 5 are connected by a neck 20.

A cartridge 4 as shown in FIG. 3 is detachably attached to the neck 20, and a filter 9 and a solid detergent 10 are placed inside the cartridge 4. A partition wall 12 is provided in the neck 20, and the funnel 3 and the washer tank 5 are not directly communicated through a water passage.

Float valve 8 consists of a float and valve 7. This float valve 8 penetrates the partition wall 12 and is installed astride the washer tank 5 and the neck portion 20. In the float valve 8, the float is located in the washer tank 5 and the valve 7 is located in the neck 20. The valve 7 has the function of opening and closing the upper opening 14 and the lower opening 15 of the neck 20.

The cartridge 4 is provided with a water intake port 17 at the top and a supply port 18 at the bottom, and the neck 20 is provided with an upper opening 14, a lower opening 15, and a washer tank 5.
A water supply port 16 is formed in the cartridge 4.
The water intake port 17 of the cartridge 4 communicates with the upper opening 14, the supply port 18 of the cartridge 4 communicates with the supply port 16 of the washer tank 5, and the lower opening 15 communicates with the drain tube 6. The cartridge 4 is provided with a filter 9. The float valve 8 can open and close the upper opening 14 and the lower opening 15 in response to the amount of washer liquid in the washer tank 5.

The window wash tank structure according to this invention has the above-mentioned structure and performs the following functions.
The funnel 3 is connected to the rain gutter 1 through which water flows from the funnel 3 into the neck 20. The wire mesh 2 installed in the funnel 3 allows rainwater, water from car washing, etc. to flow through the funnel 3.
It is possible to remove dust, etc. mixed into the water when it flows into the water.

Further, the float valve 8 functions as a type of switching valve. When there is not much washer liquid in the washer tank 5, the float valve 8 is located downward, and the valve 7 of the float valve 8 closes the lower opening 15 of the neck 20. At this time, when water is supplied from the funnel 3, the upper opening 14 of the neck 20 and the water intake port 17 of the cartridge 4 are in communication, and the valve 7 is connected to the upper opening 1.

That is, this window washer tank structure connects a funnel and a washer tank through a neck, and a cartridge containing a water-soluble solid detergent is detachably attached to the neck.
Since a float valve is installed across the wash tank and the neck, when rainwater, water from car washing, etc. enters the wash tank, it enters the cartridge containing the solid detergent from the upper opening of the neck through the water intake port. When the cartridge passes through the cartridge, a washer liquid containing detergent is produced, and then the washer liquid is supplied into the washer tank through the supply port of the cartridge and the water supply port in the neck.

Moreover, since the float valve is installed, the upper opening formed in the neck part opens and closes depending on the amount of washer fluid in the washer tank, so a predetermined amount of washer fluid is always secured. Excess water is drained through a lower opening formed in the neck.

Further, since the funnel and the cartridge are provided with filters, the water entering the washer tank is always purified and does not clog pipes or the like. Also, when it rains or when you wash your car, a detergent solution with a constant concentration is automatically created, so even if it doesn't rain for a long time, you can just pour water into it from the rainwater receiver, funnel, etc. For example, you can make a washer solution in the same way.

Furthermore, there is no need to replace the cartridge until the solid detergent in the cartridge runs out, which may take a long time, such as one year, and there is no need to inject water or liquid detergent into the washer tank. Therefore, maintenance-free operation can be achieved.
It has various effects.
