Although these right-sleeve type and left-sleeve types have different appearances, parts are commonly used due to the complexity of manufacturing and inventory management. More than 80% of the users are right-handed,
When the same operation component is used, the right sleeve type (operation with the left hand) feels heavy operation. However, if a dedicated operation mechanism is used, problems such as the complexity of manufacturing and inventory management remain. The present invention has been made in order to solve the above-mentioned conventional problems, and the object thereof is to:
It is an object of the present invention to provide a local cleaning device capable of giving the same operational feeling to both the left sleeve type and the right sleeve type by simply replacing one of the gears.

According to a third aspect of the present invention, the waterway system adjusting mechanism is a flow control valve for adjusting the flow rate of the waterway system.

According to the invention of claim 4, the gear is constituted by a transmission gear integrated with the operation knob and a power gear integrated with the valve body of the flow control valve. Since at least one is replaceable, the operating force can be easily adjusted.

Further, according to the fifth aspect of the present invention, the transmission gear ratio when the right sleeve is provided on the right sleeve is larger than the transmission gear ratio when the right sleeve is provided on the right sleeve. If the same operation mechanism is used with the right sleeve or the left sleeve, a substantially similar operational feeling can be obtained by slightly reducing the torque.

According to the sixth aspect of the present invention, since the operation knob and the transmission gear are connected and integrated by a wire, the flow control valve can be arranged at a position remote from the operation knob, so that the apparatus itself can be made compact. can do.

In the invention of claim 7, since the flow control valve is integrated with the nozzle device installed in the center of the device, the wire length can be reduced even when the operation knob is provided on either the right sleeve or the left sleeve. The diameters can be made substantially equal, and wires having the same wire diameter can be used.

In the invention according to claim 8, since a gear box is provided behind the flow control valve and a wire insertion hole is provided in the gear box, the wires can be arranged by utilizing a dead space below the front side of the nozzle device. Therefore, the apparatus itself can be made compact.

According to the ninth aspect of the present invention, since the regulating guide for regulating the direction of the wire is provided on the outer periphery of the wire insertion hole, no force due to the twisting of the wire is applied to the transmission gear, and the operating force of the knob is increased. There is nothing.

After the anal cleaning, when the cleaning stop switch 22 is operated, the electromagnetic valve 42 is controlled by a command from the controller 85.
Is closed, and the solenoid valve 46 is opened. When the electromagnetic valve 42 is closed, the supply of the cleaning water to the cleaning nozzle 53 is stopped, so that the water pressure of the cleaning water decreases. Therefore, the vacuum breaker 43
The air is supplied from inside the cylinder 51 to the gap 51 between the flat portion 53m and the spring receiving portion 51e (the protrusions 51f,
Residual water in the cylinder 51 is discharged from the gap 47g and the tube 47b, and the cleaning nozzle 53 is retracted by the resilience of the return spring 54 to return to the initial position.
2 is pressed against the inner surface of the rear cylinder 51B. On the other hand, when the electromagnetic valve 46 is opened, the cleaning water is supplied to the nozzle cleaning chamber 51m through the tube 49a and the nozzle cleaning conduit 56, thereby cleaning the outer periphery of the nozzle 53. When the nozzle cleaning is performed for a desired time, the electromagnetic valve 46 is closed by a command from the control device 50.

When the user operates the cleaning start switch 21 with the flow path switching and flow rate adjusting knob 25 at the bidet position, the solenoid valve 42 is opened by a command from the controller 85.
When the electromagnetic valve 42 is opened, the washing water is supplied from the tube 44 into the rear cylinder 51B via the washing water supply port 55a, and the water pressure causes the piston 52 and the nozzle 53 to move forward against the return spring 54. For this reason, the nozzle 53 protrudes from the front end opening 51 w of the operation cylinder 51. When the piston 52 moves forward by the maximum stroke, the peripheral portion of the pressure receiving plate 52A comes into contact with the step portion 51c and stops. When the piston 52 stops, the nozzle 53 is not moved by the piston 52, but the washing water supplied into the rear cylinder 51B is flushed with the washing water outlet 51h → the washing water outlet 66 → the washing water inflow hole 71a → the washing water inflow groove 75a. Through the rear valve portion 75
B, and flows out into the front cylinder 51A through the bidet outflow groove 75b → the bidet outflow hole 71b → the bidet outflow hole 65 → the bidet outflow inlet 51i, and the water pressure causes the flange of the nozzle 53 to flow therethrough. In order to press 53n, it further extends as shown in FIG. 26 and moves to the bidet cleaning position, where it stops when the peripheral portion of flange 53n abuts on locking portion 51e. By the movement of the nozzle 53, the bidet washing water outlet 51j → the bidet washing water outlet 64 → the bidet washing water inflow hole 71c → flows into the front valve portion 75A through the bidet washing water inflow groove 75c, and the flow rate adjusting groove 75d → washing The water outlet hole 71d → the flow control outlet 63 → the communication channel 62b → the direction changing opening 62 → the pressure chamber 61d of the diaphragm 61 via the communication channel 62a, and the diaphragm 61 comes into close contact with the side surface of the washing nozzle 53, Cleaning water is supplied to the bidet cleaning water communication port 53l → the bidet cleaning passage 53g → the bidet jetting port 53j from the cleaning water inflow port 61a provided at the tip of the nozzle 61, and the cleaning water is jetted upward from the bidet jetting port 53j to perform anal cleaning. For the desired time. When the washing stop switch 22 is operated, the nozzle 53 is washed and then returns to the initial state as in the case of the posterior washing. In addition, the flow path switching and flow rate adjustment knob 2
Cleaning switch 2 with 5 in the middle position between the buttocks and bidet
Even if 1 is operated, cleaning is not performed because the stop state is detected by the micro switch 28. If the stop switch 22 is kept pressed for a predetermined time or more in this state, the solenoid valve 42 is opened and only the nozzle 53 advances, so that the nozzle 53 can be easily wiped and cleaned.

The left-sleeve type is symmetrical to the right-sleeve type described above, and uses a power gear 77 one size larger. This requires a slightly stronger operation force than the right-sleeve type, so that the right-handed person can set the right-sleeve type and the left-sleeve type to feel the same operational feeling. The gear ratio between the transmission gear 26 and the power gear 77 is 1: 1 for the left sleeve type and 1: 0.90 to 0.9 for the right sleeve type.
It has been experimentally confirmed that the right-handed person feels substantially the same operation feeling by making the left sleeve type lighter than about five.
