The push button 25 can be provided on the side wall of the main case A as shown in FIG. 1, instead of on the top surface of the main case A as shown in FIG.

Further, as the pressure reducing mechanism E'', in addition to the bellows 24 described above, it is possible to use a pressure reducing mechanism including a set of plungers and a set of eccentric rotors.

Next, its operation will be explained with reference to the above embodiment.

By continuously repeating the pressing operation of the push button 25 and forcibly expanding and contracting the bellows 24, a negative pressure state is created in the water supply pipe 4, and the flushing tank 5 is caused by the action of the negative pressure.
The water inside can be supplied to the cleaning tank 1.

That is, by pressing the push button 25, the bellows 24
is compressed and deformed, and the air inside the bellows 24 is released into the check valve 2.
6 is forcibly opened and pushed out through the discharge pipe 27, and the bellows 24 is restored to its old form by releasing the pressed state of the push button 25. In the process of restoring to normal state, the inside of the bellows 24 becomes in a negative pressure state.

Since the inside of the bellows 24 becomes a negative pressure state, the air accumulated in the water supply pipe 4 is sent into the bellows 24 through the suction pipe 22.

By continuously repeating the pressing operation of the push button 25, it is possible to create a negative pressure state within the water supply pipe 4.

When the negative pressure in the water supply pipe 4 becomes equal to or higher than a certain pressure, the water in the flush tank 5 is sucked into the water supply pipe 4 according to the siphon principle, and the water sucked into the water supply pipe 4 flows into the water supply pipe 4. The water is supplied into the cleaning tank 1 built into the main body case 1 through the passage 15, port 16, and outflow passage 17.

When the water level in the cleaning tank 1 reaches a preset full water level line position, the maximum level switch R3W2 is closed through the action of the float 3.

When the maximum level switch R8W2 is closed, the solenoid valve SV1 is closed in conjunction with the maximum level switch R8W2, and further water supply to the cleaning tank 1 is stopped.

In addition, when the heater HA is set automatically via the changeover switch SW1, the heater HA starts its operation in conjunction with the closing of the maximum level switch R5W2, and the cleaning inside the cleaning tank 1 is started. This will cause the water to become warmer.

Note that it is also possible to arbitrarily operate the heater HA manually via the manual changeover switch SW2.

When the cleaning water is heated to a preset temperature by the action of the heater HA, the heater HA stops its action by the action of the thermostat SM, and thereafter the temperature is maintained at a constant temperature by repeating the intermittent action of the thermostat. be.

In this way, when a certain amount of hot cleaning water is stored in the cleaning tank 1 and the cleaning water is to be jetted out, a method is selected in which the cleaning water is jetted out from the fixed nozzle D. In such a case, press the fixed nozzle ejection push button SW3 while the hand-held nozzle rod C is inserted into the storage chamber 7 to turn on the ejection pump P.
starts to rotate, and through the rotation of the jet pump P, the cleaning water in the cleaning tank 1 is jetted out from the fixed nozzle D via the main water pipe 6 and the branch pipe 6a.

On the other hand, if you choose the method of spouting cleaning water from the hand-held nozzle rod C, contrary to the above, the hand-held nozzle rod C
By pulling out the microswitch MSW from the storage chamber 7, the microswitch MSW, which had been pressed downward by the flange 9, is pushed upward through its repulsive action.

Through the upward repulsive action of this microswitch MSW, the solenoid valve S, which had been in the open state until now, is
V2 operates in the closing direction, and the pipe branch 6a connected to the fixed nozzle D is closed.

By blocking the pipe branch 6a connected to the fixed nozzle D in this way, the cleaning water sent out from inside the cleaning tank 7 through the driving action of the jet pipe P is transferred to the main water pipe 6.
Then, it is forced to be fed in the direction of the other pipe branch 6b.

The cleaning water pumped through the pipe branch 6b can be released from the spout 11' of the spout nozzle 11 by pressing the push button 12 provided on the grip 8 of the hand-held nozzle rod C.
It is possible to make more water erupt.

After the use of the handheld nozzle rod C is completed, by returning the two-handed nozzle rod C to the storage chamber 7, the microswitch MSW will be pushed downward through the contact action of the flange piece 9. However, by pushing down the microswitch MSW in this way, the solenoid valve S2 returns to the open state again.

By using the cleaning water in the cleaning tank 1 as described above, the water level in the cleaning tank 1 will drop, but the water supply to the cleaning tank 1 will not be replenished during use. Only by releasing the pressed state of the push button SW3 or returning the hand-held nozzle rod C to the storage chamber 7, the solenoid valve S is opened and the cleaning tank 1 is refilled. .

The present invention has the above-mentioned configuration, and as described above, a check valve mechanism that can be opened only toward the washing tank is provided at an arbitrary intermediate position of the water supply pipe 4 that connects the washing tank 5 and the washing tank 1. A bypass passage consisting of a suction pipe and a discharge pipe stands up from the front and rear positions of the check valve mechanism with a check valve mechanism in between, and the upper end of the bypass passage is provided so as to communicate through a bellows. The bellows are provided so that they can be compressed and deformed through a pressing operation, and check valves that can be opened only toward the cleaning tank are interposed at the upper ends of both pipes, and negative pressure is created in the water supply pipe 4 through the compressive deformation of the bellows. The water in the washing tank 5 is transferred to the washing tank 1 through the action of the negative pressure generated in the water supply pipe 4.
By supplying water to the cleaning tank 1, it is possible to supply water to the cleaning tank 1 at a lower cost and with a simpler mechanism than when an electric pump mechanism is used.

In addition, as shown in Utility Model Publication No. 10272/1983, a piston is inserted into the pump outer cylinder, and a negative pressure is generated in the pump outer cylinder through the suction action of the piston, and the pressure inside the tank is generated through the negative pressure action. The method of draining the liquid requires effort to suction the piston, and it must be done with both hands, such as holding down the pump outer cylinder with one hand and pulling the piston with the other hand. However, with the present invention, it is possible to obtain the water supply effect by simply pressing the push button several times with one hand. be.

Also, a solenoid valve SV1 is provided in the outflow passage 17, and the solenoid valve S1 is opened and closed in conjunction with the liquid level switch LS provided in the cleaning tank 1, so that After water is supplied into the cleaning tank 1 by manual operation, water can be automatically replenished according to changes in the water level in the cleaning tank 1, and the practical effect in this respect is extremely large. be.
