In addition, the collecting tank 121 is connected to the washer liquid tank 111 through the water supply hose 125, wherein the collecting tank 121 has a lower end thereof higher than the upper end of the washer liquid tank 111.

In addition, by limiting the amount of rain water introduced through the collection hose 123 in the collection tank 121, the inlet 121a of the collection tank 121 is disposed so that the water level of the collection tank 121 does not exceed a predetermined level. The switch 124 for opening and closing is provided.

The switch 124 has a stopper 124a and a guide 124b extending upward from the stopper 124a. The switch 124 floats on the rainwater stored in the collection tank 121 and is lifted up and down in accordance with the water level of the rainwater. Since the switch 124 maintains a state in which the guide 124b is always inserted into the inlet 121a, the switch 124 is always lifted up and down directly below the inlet 121a, and the water level of the collection tank 121 is higher than a predetermined level. When the stopper 124a blocks the inlet 121a, the rainwater no longer flows into the collection tank 121.

In addition, the washer fluid tank 111 connected to the collection tank 121 through the water supply hose 125 is provided with a switch 126 having the same structure to open and close the inlet 121a through which the rainwater flows from the collection tank 121. .

On the other hand, the concentrated washer liquid supply unit is for supplying the washer liquid to the washer liquid tank 111 for mixing with the rain water supplied from the rain water supply to form a washer liquid.

The concentrated washer liquid supply unit has a concentrated washer liquid tank 127 in which the concentrated washer liquid is stored, and a control unit for controlling the operation of the electric valve 128 and the electric valve 128.

The concentrated washer liquid tank 127 is provided above the washer liquid tank 111 and is connected to the concentrated washer liquid inlet 111b of the washer liquid tank 111. In addition, a refill inlet 127a for replenishing the concentrated washer liquid is formed at the upper end of the concentrated washer liquid tank 127.

Then, the electric valve 128 is installed to open and close the concentrated washer liquid inlet 111b of the washer liquid tank 111.

The control unit has a first water level sensor 129a for detecting the first water level of the washer liquid tank 111, and a second water level sensor 129b for detecting the second water level of the washer liquid tank 111.

The first water level sensor 129a is for applying an open signal to the electric valve 128 by detecting the first water level, and the first water level is blocked by the inlet 111a of the washer liquid tank 111 by the switch 126. It is desirable to be at or slightly below the water level.

The second level sensor 129b is for applying a closing signal to the electric valve 128 by sensing the second level, and the second level detected by the second level sensor 129b is higher than the first level.

Looking at the action of the washer fluid supply device according to an embodiment of the present invention having such a configuration as follows.

A part of the rainwater falling on the car in rainy weather is collected in the water collector 122, and flows into the water collecting tank 121 through the water collecting hose 123 and the water filter 130. Rainwater introduced into the collection tank 121 is again introduced into the washer liquid tank 111 through the water supply hose 125.

When the water level of the washer liquid tank 111 rises to a certain value, here the first level, the first level sensor 129a detects this and applies an open signal to the electric valve 128. Accordingly, the electric valve 128 opens the concentrated washer liquid inlet 111b of the washer liquid tank 111, and the concentrated washer liquid stored in the concentrated washer liquid tank 127 is injected into the washer liquid tank 111. The concentrated washer liquid injected into the washer liquid tank 111 is mixed with rain water and diluted.

When the water level of the washer liquid tank 111 is approximately close to the first water level, the switch 126 of the washer liquid tank blocks the inlet 111a of the washer liquid tank 111. Accordingly, the rainwater no longer flows into the washer liquid tank 111. In addition, the rainwater introduced into the collecting tank 121 is stored in the collecting tank 121, when the water level is raised to a certain level, the switch 124 of the collecting tank 121 is the inlet ( Block 121a).

On the other hand, as the concentrated washer liquid is injected and mixed with rain water, the level of the washer liquid tank 111 continues to rise, and when the water level reaches the second level, the second level sensor 129b detects this and transmits it to the electric valve 128. The closing signal is applied. Accordingly, the electric valve 128 blocks the concentrated washer liquid inlet 111b of the washer liquid tank 111 so that the concentrated washer liquid is no longer injected into the washer liquid tank 111.

In this way, the washer liquid made by mixing the rain water and the concentrated washer liquid is pumped by the pump 112 connected to the washer liquid tank 111 when the driver operates the switch and is injected into the windshield glass 101 through the nozzle 113.

When the level of the washer liquid tank 111 is lowered by continuous use, the switch 126 is lowered to open the inlet 111a of the washer liquid tank 111. Therefore, rainwater stored in the collecting tank 121 flows into the washer liquid tank 111. In addition, the electric power valve 128 is opened by the first water level sensor 129a, and the concentrated washer liquid is injected into the washer liquid tank 111. By repeating this process, the washer fluid tank 111 always stores a certain amount or more of washer fluid.

In addition, rainwater of the collecting tank 121 is replenished by rainwater being introduced into the collecting tank 121 through the water collector 122 in the rain. Therefore, the driver does not have to search the water level of the washer fluid tank 121 and has to make the effort to replenish the washer fluid. However, the concentrated washer liquid may be replenished once or twice a year through the supplemental inlet 127a of the concentrated washer liquid tank 127. And only when the rain does not come for a long time to replenish the water through the water collector (122).

As described above, the present invention receives rain water and stores it, and supplies it to the washer fluid tank together with the concentrated washer fluid to make the washer fluid. Thus, the inconvenience of having to check the washer fluid tank and replenish the washer fluid as in the prior art Can be.

In the above, specific preferred embodiments of the present invention have been illustrated and described.
