In FIG. 3, reference numerals 12 and 13 denote a cylindrical first nozzle body for cleaning the anus and a second similarly cylindrical nozzle body for bidet cleaning. The second nozzle main body 13 is fixed on a line so as to be oriented toward the toilet bowl 1a, while the second nozzle main body 13 is provided with its axis inclined to the left in FIG. Inside the first and second nozzle bodies 12 and 13, a piston-shaped first telescopic nozzle 14 and a second telescopic nozzle 15 are arranged to be slidable in the axial direction and are provided with springs that bias them in the retraction direction. In addition, there is a spout hole 1 at the tip of both telescopic nozzles.
4a and 15a are drilled in the required number. The first nozzle main body 12 and the first telescopic nozzle 14 provide an anal ejection part 6a.
However, the second nozzle main body 13 and the second telescoping nozzle 15 form the bidet ejection part 6b.

A first inflow part 12a is provided at the upper end of the first nozzle body 12, and a second inflow part 13a is provided at the upper end of the second nozzle main body 13. Due to the water pressure, the first and second telescopic nozzles 14 and 15 extend in the direction of the toilet bowl 1a inside the first and second nozzle bodies 12 and 13, respectively, against the urging force of the spring, and reach their respective cleaning positions. Cleaning water can be sprayed locally from the spray holes 14a and 15a. Both the above spouting parts 6a, 6
Cleaning water is supplied to b from the hot water storage tank 8, and its piping system will be described below.

A hot water discharge pipe 20 is connected to the upper end of the hot water storage tank 8, and the hot water discharge pipe 20 communicates with an inflow portion 21a of a three-way switching solenoid valve 21. For example, the three-way switching solenoid valve 21 shown in FIG. 4 is used, and the solenoid valve 21 has three openings: an inlet 21a, a first outlet 21b, and a second outlet 21c. 21d is a valve seat between the inflow part 21a and the first outflow port 21b, 21e is a valve seat between the inflow part 21a and the second outflow port 21c, and valve bodies 21f and 21g that come into contact with and separate from both valve seats are provided, respectively. There is. Furthermore, 21h is the core assembly, 2
1i is a shading coil, 21j is a plunger, 2
Reference numeral 1k denotes a spring, and when the power is not energized, the inflow portion 21a and the first outlet 21b communicate with each other in the state shown in FIG. At the same time, the valve element 21g moves away from the valve seat 21e to open the valve, and the inflow part 2
1a and the second outlet 21c can be brought into communication.

A first supply pipe 22 is provided between the first outlet 21b and the first inlet 12a of the first nozzle body 12, and a first supply pipe 22 is provided between the second outlet 21c and the second inlet 13a of the second nozzle body 13. The second supply pipes 23 are connected to each other. Vacuum breakers 24 and 25 are provided midway between the first and second supply pipes 22 and 23 to prevent backflow.

Further, a drain pipe 26 connected to the upstream side of the valve portion of the flow rate control valve 11 is similarly provided with a vacuum breaker 27 in the middle, and its open end is located near the spout portion 6 to adjust the flow rate. The excessive flow rate due to this can be drained into the toilet bowl 1a.

In addition, the hot water storage tank 8 is equipped with a temperature sensor for detecting the temperature of the cleaning water as well as the sheathed heater that serves as the heater described above, and is controlled so that cleaning water at a comfortable temperature can be supplied at all times. A circuit section is provided to control power supply to the sheathed heater. In addition to this control circuit, the solenoid valve 9
An electric circuit is configured to open and close the three-way switching solenoid valve 21, and the cleaning process will be described below.

First, when the anal cleansing switch 5b is turned on, the solenoid valve 9 opens, water is supplied and flows into the hot water tank 8, and the warm water heated and stored in the hot water tank 8 is pushed out. The hot water is discharged from the discharge pipe 20 in this manner. In this case, the flow rate of the cleaning water can be adjusted using the rotary dial 7 of the flow rate control valve 11. When the anus cleansing switch 5b is on, the three-way solenoid valve 21 is not energized, and therefore, as described above, the inlet 21a and the first outlet 21b are in communication with each other, so the hot water from the discharge pipe 20 is flows into the main body,
The first telescopic nozzle 14 is extended to the anus cleaning position, and cleaning water is discharged from the ejection hole 14a to perform cleaning.

After the cleaning is completed, by turning off the anal cleaning switch 5b, the solenoid valve 9 is closed, and by closing the valve, the cleaning water pressure in the first nozzle body 12 is reduced, and the jetting of cleaning water is stopped. Due to the restoring force of the spring, the first telescopic nozzle 14 is retracted and accommodated within the first nozzle body 12, completing one process.

On the other hand, in the case of bidet cleaning, when the bidet cleaning switch 5c is turned on, the solenoid valve 9 is opened in the same manner as described above, and the three-way switching solenoid valve 21 is also energized to open the inlet portion 21a as described above. The cleaning water from the hot water discharge pipe 20 flows into the second nozzle body 13 from the second inflow portion 13a of the second nozzle body 13, and the second expansion and contraction occurs in the same manner as above. Bidet cleaning can be performed by extending the nozzle 15 to the bidet cleaning position and jetting cleaning water from the jet hole 15a at the same position.

When the bidet cleaning switch 5c is turned off, the solenoid valve 9 is closed and the energization to the three-way solenoid valve 21 is also stopped, resulting in the state shown in FIG. 4, that is, the inlet 21a and the first outlet 21b. The communication state is established, and the supply of cleaning water to the second nozzle main body 13 is stopped, and the second telescopic nozzle 1
5 is retracted and stored in the second nozzle body 13, and the cleaning process is completed.

[0021] In addition, in the water supply heating device 5, after washing the private part,
A hot air drying device may be added that blows out hot air to dry the cleaning water adhering to the area.

The present invention is not limited to the above-described embodiments, but can be modified in various ways. That is, an electric valve, an electric pump, or the like may be used instead of the solenoid valve 9. Further, instead of the three-way solenoid valve 21, a three-way electric valve or the like may be used.

[0023]

[Effects of the Invention] According to the present invention, a three-way switching electrically operated valve is provided on the downstream side of the heater to communicate either the anal jetting part or the bidet jetting part to the heater side. Therefore, a dedicated solenoid valve is not required for each of the two jetting holes, and therefore the number of parts can be reduced, wiring and piping work for the cleaning water jetting system can be easily performed, and manufacturing costs can also be reduced.
