[Embodiment 1] Hereinafter, a washer / processing device of the present invention will be described in detail with reference to the drawings. 1 is a block diagram of a washer / processing device according to a first embodiment of the present invention. The washer / processing device of the present embodiment mixes a fixed amount of the processing liquid when the washer liquid is injected once. In the figure, in addition to the conventional washer system, the washer / processing device of this embodiment includes a processing liquid tank 110, a processing liquid pump 109, a processing liquid supply amount adjusting device, a processing liquid pipe 118, and a check valve (first valve). 1 check valve) 1
It is configured by including 19.

Here, the conventional washer system includes a washer liquid tank 103 for storing the washer liquid A, a washer liquid pump 102 for sending the washer liquid A to the jet nozzle 105, and a jet nozzle 1 for jetting the washer liquid A.
05, a washer switch (switch means) 101 for controlling the operation of the washer liquid pump 102, and a washer liquid conduit 106 for guiding the washer liquid A from the washer liquid pump 102 to the injection nozzle 105. Note that the washer switch 101 controls the operation of the washer liquid pump 102 and the processing liquid pump 109 by the introduction to this embodiment.

The treatment liquid tank 110 stores a treatment liquid B such as a water repellent liquid or a hydrophilic liquid, and the treatment liquid pump 109
The processing liquid B is sent out by. That is, the processing liquid pump 109
Is supplied from the outlet 109-4 by the rotor 109-3 which rotates the processing liquid fed from the processing liquid tank 110 through the inlet 109-0 by the motor 109-1 around the rotation shaft 109-2. Room 1 of quantity control device
Send to 08.

Further, the processing liquid supply amount adjusting device adjusts the supply amount of the processing liquid B in order to merge the processing liquid B from the processing liquid tank 110 with the washer liquid supply path (the washer liquid pipe 106). Processing liquid line 11 provided with stop valve 119
Send to 8. In addition, the processing liquid supply amount adjusting device is provided in the chamber
8, spring 111, piston 112, upper end portion 1 of the piston
13, a check valve (second check valve) 114, a chamber 115, and an outlet 117.

Next, the operation of the washer / processing device of this embodiment will be described. When the washer switch 1 is turned on, the washer liquid pump 102 is activated to send the washer liquid A in the washer liquid tank 103 toward the jet nozzle 105. Therefore, the washer fluid line 10
There is a flow of washer fluid at 6.

The treatment liquid B is introduced into the chamber 108 from the treatment liquid tank 110 through the treatment liquid pump 109. That is, in the treatment liquid pump 109, the treatment liquid B sent from the treatment liquid tank 110 through the inlet 109-0 is rotated by the motor 109-1 around the rotation shaft 109-2 by the rotor 109-3 and the outlet 109. -4 to the chamber 108.

The processing liquid B introduced into the chamber 108 pushes the stepped piston 112 upward in the figure. Also, when the piston 112 is pushed upward, its upper end 11
3 is a chamber 1 from the processing liquid tank 110 through a check valve 114.
Since the treatment liquid B introduced in 15 is pushed up, the treatment liquid B is
Is an outlet 117, a processing liquid line 118, and a check valve 119.
And the washer liquid conduit 106 is merged.

The amount of the processing liquid B to be merged is defined by the amount pushed out while the piston 112 moves from the lowermost position to the uppermost position. Further, the pushing pressure can be increased from the pressure of the processing liquid B introduced into the chamber 108 to a pressure determined by the vertical pressure receiving area of the stepped piston 112 and the spring force of the spring 111. Therefore, the pressure in the pipe 18 can be set higher than the pressure in the pipe 6, and the processing liquid B can always join the washer liquid A.

The processing liquid B that has merged with the washer liquid A is jetted from the jet nozzle 105 toward the window.
The sprayed treatment liquid B hits the window surface and is wiped off by the wiper, so that it is evenly applied to the window surface. Further, since the droplets of the treatment liquid are also splashed on the area which is not wiped by the wiper, the window surface is treated to be water repellent or the like.

After that, although the processing performance is deteriorated by wiping with a wiper or ultraviolet rays, the processing performance is restored when the washer is used next time. By repeating this, the driver can always maintain a window with high processing performance.

[Embodiment 2] FIG. 2 is a block diagram of a washer / processing device according to Embodiment 2 of the present invention. The washer / processing device of the present embodiment is an embodiment that saves the consumption of the processing liquid B. In the following description, a water-repellent liquid is used as the treatment liquid B, but it goes without saying that the same applies to a hydrophilic liquid.

In this embodiment, the throttle valve (first throttle means) 21 having a threaded portion in the processing liquid supply controller of Embodiment 1 is used.
6 is provided and the outflow rate of the water-repellent liquid B can be adjusted by manually adjusting the rotation of the throttle valve 216.

For example, in an environment where there are many opportunities to travel on a snowy road, the washer is frequently used, so that the amount of the water repellent liquid B used becomes larger than necessary. In order to prevent the water repellent liquid B from being used more than necessary, the outlet valve 1 is adjusted by adjusting the throttle valve 216.
The flow rate of the water repellent liquid B extruded through 17 is reduced. As a result, the time required for the piston 112 to move from the lowermost position to the uppermost position can be made considerably longer than the normal washer injection time. In other words, within the normal washer injection time, the piston 112 can move only from the lowermost position to a position significantly lower than the uppermost position, and as a result, the outflow rate of the water repellent liquid B by one washer injection is increased. Can be adjusted less.

[Third Embodiment] FIG. 3 is a block diagram of a washer / processing device according to a third embodiment of the present invention. The washer / processing device of this embodiment is another embodiment that saves the consumption of the processing liquid (water repellent liquid) B. In this embodiment, a stopper (first squeezing means) 320 is provided in the treatment liquid supply adjusting device of the first embodiment, and the position of the tip of the stopper 320 is changed by manually rotating and adjusting the stopper 320. It is configured so that the outflow rate of B can be adjusted.

This is equivalent to lowering the uppermost position of the piston 112 to the position of the tip of the stopper 320 in the chamber 115 of the treatment liquid supply control apparatus of the first embodiment, and as a result, water repellency sprayed once The upper limit of the total amount of liquid B can be adjusted.

[Fourth Embodiment] FIG. 4 is a block diagram of a washer / processing device according to a fourth embodiment of the present invention. The processing device that also serves as a washer of this embodiment is an embodiment in which a small amount of the processing liquid (water repellent liquid) B is mixed by controlling the flow rate. In the figure, the washer / processing device of the present embodiment has a processing liquid tank 110, in addition to the conventional washer system.
The processing liquid pump 109, the flow control valve, the processing liquid pipe 118 and the check valve 119 are provided.

The treatment liquid B is stored in the treatment liquid tank 110, and the treatment liquid pump 109 sends the treatment liquid B from the outlet 109-4 to the flow control valve. The flow control valve allows the processing liquid B from the processing liquid tank 110 to pass through the washer liquid pipeline 1.
In order to merge with 06, the flow rate of the processing liquid B is adjusted and sent out to the processing liquid pipe 118 provided with the check valve 119. The flow control valve includes a spool 426, a throttle 427, a spring 428, passages 429 and 430, and an outlet 417.
It has.

Next, the operation of the washer / processing device of this embodiment will be described. If the flow control valve is not provided in the embodiment of FIG. 4, the pressure in the washer liquid conduit 106 fluctuates due to the rotational fluctuation of the washer liquid pump 102, and if the pressure rises above normal, the internal pressure in the processing liquid conduit 118 will increase. There is a phenomenon in which the pressure difference between the water-repellent liquid B and the water-repellent liquid B that flows into the washer liquid conduit 106 decreases. On the contrary, when the pressure in the washer liquid pipeline 106 decreases, the processing liquid pipeline 1
The internal pressure of 18 may be relatively higher than the internal pressure of the washer liquid conduit 106, and a phenomenon may occur in which a larger amount of the water-repellent liquid B than usual joins. In other words, this embodiment has an effect of always joining a fixed amount of the processing liquid through the flow control valve.

To explain the operation, the spool 426 is pushed leftward in the drawing by the spring 428. Further, the spool 426 has a throttle 427, and the processing liquid pump 109
The water-repellent liquid B extruded from the outlet 109-4 of FIG. 1 pushes the spool 426 to the right in the figure, and also passes through the throttle 427 to enter the chamber on the left side of the spool 426. After that, passage 43
0, outlet 417, processing liquid line 118 and check valve 119
And joins the washer liquid pipe line 106.

Assuming that the pressure in the washer liquid conduit 106 is low, the pressure applied to the right side of the spool 426 is small, so that the flow rate of the water repellent liquid B passing through the throttle 427 tends to increase. At this time, since the pressure difference with the pressure applied to the left side of the spool 426 is large, the spool 426 is pushed rightward in the drawing to open the passage 429 further. Therefore, the spool 4
The pressure applied to the left side of FIG. 26 in the figure is reduced, and the increase of the water repellent liquid B passing through the throttle 427 is prevented.

On the contrary, when the pressure of the washer liquid pipe line 106 becomes high, the pressure applied to the right side of the spool 426 becomes large, and the passage 429 moves in the direction of squeezing the spool 4
The pressure applied to the left side of 26 in the figure is increased.

As a result, the flow rate of the water repellent liquid B passing through the diaphragm 427 is kept constant. That is, the spool 426
Moves so that the pressure difference applied to both ends of the throttle 427 is always constant. That is, considering the balance of the forces applied to the spool 426, the pressure applied from the left side in the figure is P1, the pressure applied to the right side in the figure is P2, and the spring 428 causes the spool 4 to rotate.
When the force for pushing 26 to the left in the figure is F and the pressure receiving area of the spool is the same on the left and right, A is given as A × (P1−P2) = F, that is, the pressure difference on both sides acting on the spool 426 is controlled. Shows.

[Embodiment 5] FIG. 5 is a block diagram of a washer-cum-processing apparatus according to Embodiment 5 of the present invention. The washer / processing device of the present embodiment is provided with a washer liquid tank 10
In order to prevent a large amount of only the treatment liquid (water repellent liquid) B from being jetted when 3 becomes empty, the structure in which the water repellent liquid B is not jetted for a certain period of time after jetting the water repellent liquid B is carried out. Here is an example.

In this embodiment, in the treatment liquid supply controller of the second embodiment, the water repellent liquid B flowing from the treatment liquid tank 110 through the check valve 114 into the chamber 115 is throttled (second
A diaphragm means) 521 is provided. That is, after the water repellent liquid B in the chamber 115 is pushed out, the piston 11
2 is tried to return to the lower side in the figure by the spring 111,
Since the flow rate of the water-repellent liquid B supplied from the treatment liquid tank 110 to the chamber 115 is small due to the throttle 521, the descending speed of the piston 112 is slow and the amount of the water-repellent liquid B in the chamber 115 only gradually increases.

Therefore, when the driver turns on the washer switch 101 in order to operate the washer, the water repellent liquid B accumulated until then is sprayed into the chamber 115, but only a small amount of the water repellent liquid B is ejected. The driver turns on the washer switch 101 again to inject the fuel. This time,
Room 1
The water-repellent liquid B is hardly accumulated in 15 and is hardly jetted.

A water repellent switch (second switch means) 62 for controlling on / off of the processing liquid pump 109 and the processing liquid pump 109 in conjunction with each other.
It is configured by replacing with 4.

That is, when the water repellent switch 624 is turned on, the washer liquid pump 102 and the treatment liquid pump 109 are simultaneously operated, and when only the washer switch 101 is turned on, only the washer liquid pump 102 is operated. Therefore, the driver can apply water repellency only when he / she needs it.

[Embodiment 7] FIG. 7 is a block diagram of a washer / processing device according to Embodiment 7 of the present invention. The washer / processing device of this embodiment is an embodiment relating to a switch for operating the processing liquid pump and the washer liquid pump.

In this embodiment, in the treatment liquid supply adjusting device of the fifth embodiment, a washer switch (first switch means) 101 is used, and a water repellent switch (second switch means) for performing on / off control of only the treatment liquid pump 109. ) 724 is added in series. That is, when the washer switch 101 is on, the washer fluid pump 10
2 operates, but the treatment liquid pump 109 operates only when the washer switch 101 is on and the water repellent switch 724 is on. Therefore, the driver can apply water repellency only when he / she needs it.

[Embodiment 8] FIG. 8 is a block diagram of a washer / processing device according to Embodiment 8 of the present invention. The washer / processing device of the present embodiment is an embodiment in which the control is automated in order to make the operation of the processing liquid pump 109 more appropriate, and the processing liquid pump 109 is operated only when the washer liquid pump 102 is operating and when necessary. It is made water repellent.

In this embodiment, a control circuit (control means) 82 for controlling the operation of the treatment liquid pump 109 is applied to the washer switch 101 in the treatment liquid supply adjusting device of the second embodiment.
5 is added in series.

After describing the concept of this embodiment, the operation will be described. A water repellent switch (not shown) provided in the control circuit 825 is turned on only when the washer switch 101 is on and water repellent is required. The treatment liquid pump 109 does not operate unless the water repellent switch is turned on. The operating time of the treatment liquid pump 109 is substantially proportional to the water repellent liquid injection amount, and the water repellent liquid injection amount substantially corresponds to the water repellent performance improvement value. Therefore, if the operating time of the treatment liquid pump 109 is known, the current approximate value of the water repellent performance can be known from the relationship between the water repellent spray injection amount and the water repellent performance improvement value measured in advance.

Normally, when a washer is used, it is made sufficiently water-repellent by jetting a water-repellent liquid during an average washer liquid pump operating time, and its water-repellent performance gradually deteriorates. Lasting water repellent effect.

Therefore, if the operation time of the treatment liquid pump 109 is longer than the time required for sufficient water repellency, it is judged that the water repellency has been achieved, and the water repellency is maintained for a certain period thereafter (after the injection of the water repellent liquid). It can be judged that the water remains.

Next, the operation control of the processing liquid pump 109 in the control circuit 825 shown in FIG. 9 will be described with reference to the flowchart. The water repellent liquid B is jetted only when both the conditions of "the washer switch 101 is on" in step S901 and "the water repellent switch is on" in step S902 are satisfied.

In step S903, the jetting time of the water repellent liquid B until the washer switch 101 is turned off (step S904) or the water repellent switch is turned off (step S902) is measured, and the water repellent liquid jetting time is measured. Let Tn.

In step S905, if the water-repellent liquid injection time Tn is longer than the predetermined time T0, it is determined that the water-repellent property has been sufficiently made, and the deterioration time T is determined in step S906.
After setting d to zero, the water repellent switch is turned off in step S907 to stop the subsequent water repellent liquid injection.

After the water-repellent switch is turned off, the deterioration time Td (elapsed time) is measured in step S906, and the estimated time Td0 until the water-repellent effect is lowered and reprocessing is required has elapsed in step S909. If it has elapsed, the water repellent switch is turned on in step S910.
Return to 01.

Further, in step S905, when the water repellent liquid injection time Tn is shorter than the predetermined time T0,
Assuming that the water repellent property is insufficient, the water repellent liquid injection time Tn is returned to zero in step S911, and the water repellent switch remains on.

That is, the water repellent liquid injection time Tn is returned to zero in step S911, and the deterioration time Td is calculated in step S912.
(Elapsed time) is measured, and it is determined in step S913 whether the estimated time Td0 until the water-repellent effect is lowered and reprocessing is required has passed.
In step 4, the water repellent switch is turned on, and when the time has not passed, the process remains as it is, and the process returns to step S901.

Thus, for example, if the water-repellent liquid jet time is 5 seconds, the water-repellent liquid B can be effectively used by not jetting the water-repellent liquid for the next two weeks.

[Ninth Embodiment] FIG. 10 shows a ninth embodiment of the present invention.

Presuming that the water-repellent liquid B cannot be jetted when the water-repellent performance that the driver feels is sufficient or lower,
An appropriate injection of the water repellent liquid B was made possible.

Next, at step S1010, if the current water-repellent performance Et is equal to or more than the water-repellent performance upper limit value Emax, the injection of the water-repellent liquid B is not necessary for the time being, so step S10.
At 1011 the water repellent switch is turned off. If the water repellent performance Et at the present time is equal to or less than the water repellent performance upper limit value Emax in step S1010, the deterioration time Td is measured by measuring the time immediately after the last injection of the water repellent liquid B in step S1016. And the deterioration performance Ed at that time
Is calculated.

Good. Alternatively, a relational data map between the deterioration time Td and the water repellent performance Et may be created and estimated from this.

From this, again in step S1017, the current water-repellent performance Et = Et-Ed is estimated, and step S
At 1018, it is determined whether the current water-repellent performance Et is less than or equal to the water-repellent performance lower limit value Emin.

In step S1018, when the water repellent performance lower limit value Emin or less is reached, the water repellent switch is turned on in step S1019, and the process returns to step S1003 to enable another water repellent liquid injection. In step S1018, if the water repellent performance lower limit value Emin or more, it is left as it is, and the process returns to step S1003 to repeat these routines.

After the water repellent switch is turned off in step S1011, the deterioration time Td is set in step S1012.
(Elapsed time) is measured and the deterioration performance Ed is calculated. In step S1013, the water repellency performance Et = Et−Ed is estimated, and in step S1014 it is determined whether the water repellency performance Et is less than or equal to the water repellency performance lower limit value Emin.

If the water repellent performance lower limit value Emin is not exceeded in step S1014, the water repellent switch is turned on in step S1015, and the process returns to step S1003 to enable another water repellent liquid injection. In step S1018, if the water repellent performance lower limit value Emin or more, it is left as it is, and the process returns to step S1003 to repeat these routines.
