The cleaning switch 52 is pressed when cleaning the bidet, the bidet cleaning switch 53 is pressed when cleaning the bidet, and the fine movement operation part (from the switch etc. ) 54 etc. are provided.

These switches are housed in the casing of the control device 5, and are connected to an electric circuit as shown in the figure, which instructs the electric motor 21 to start/stop and rotate forward/reverse.

Then, the re-cleaning switch 52, 53 and the fine movement operation section 54
When the sanitary cleaning device is not in use and is not in contact with
5 is accommodated in the outer cylinder 14, the nozzle cylinder 3
is retracted, and its tip is inserted into the opening 2 of the housing 1.
The band-shaped leaf spring 1 is wound around the outer peripheral surface of the rotary drum 5.

Next, the operation of the above configuration will be explained with reference to FIG. 8 as well.

When the sanitary cleaning device is first used, the nozzle tube 3 is in the state shown by the solid line in FIG. 1 described above.

When cleaning the anus (hereinafter referred to as the private part), when the cleaning switch s2 is pressed on the operation panel 51, a solenoid valve (as shown) that controls the flow of hot water into the nozzle tube 3 is activated.
The valve is opened for a set period of time, for example, about 2 to 3 seconds by the timer circuit T1, and the hot water that flows into the hot water introduction boat 17A flows into the nozzle cleaning channel 25 and is discharged from the open end of the outer cylinder 14 into the toilet bowl. 6 Then, the first and second injection ports 211.21 located facing the cleaning water channel 25 are cleaned, and the hot water supply piping and the cleaning water passage 22 are cleaned.
．． The cold flush water that filled the 24 etc. is discharged into the toilet bowl.

At the end of the above set time, the timer circuit T1 temporarily closes the solenoid valve and then closes the electric I! 21 is energized for a predetermined period of time to rotate the rotary drum 5 by a predetermined angle in the direction of arrow a in FIG. The tip is plug body 1! Press,
When the tip of the inner cylinder IS finishes advancing to the forward position shown by the dashed line in FIG. 1, the electric motor 27 is de-energized and the solenoid valve is opened again.

At this time, the movement of the outer cylinder 14 is restrained by the connecting rod 13 attached to the rear end, so that the relative positions of the inner and outer cylinders 14 and Is are as shown in FIG. Therefore, since the hot water introduction boat 17A and the first injection port 2 are communicated with each other via the communication hole 23B provided in the inner cylinder 15 and the water passage 24, the first injection port 2I is directed toward the private part. The hot water for cleaning is injected, and this injection continues until the cleaning switch 52 is released from the press.

Note that when the cleaning switch 52 is pressed, the rotating drum 5
With the above-mentioned rotation, the engaging pin protruding from the rotary drum 5 becomes fitted into the pin holder 11 of the Geneva gear 12.

During private cleaning, by slightly moving the position of the first injection port 21,
When you want to completely clean the surrounding area of your private parts, use the fine movement operation part 5.
When 4 is operated, the timer circuit T2 and the electric motor/reverse circuit are operated, and the electric motor 27 is rotated forward and backward at the rotation angle and cycle set in the timer circuit T2.

The engaging pin 1, which is protruded from the rotary drum 5 to which this movement of the electric motor 21 can be transmitted, and which is fitted in the bottle holder 1, moves the Geneva gear 12 around the pin 3 as shown in FIG. It is oscillated within the range shown by the one-dot chain line and the two-dot chain line. This rocking motion is caused by the pin 31 provided on the Geneva gear 12 and the outer cylinder 1.
The information is transmitted to the nozzle tube 3 via a connecting rod 13 that connects the pin 32 provided in the nozzle tube 3 to the guide rail 2.
It is moved back and forth along 6. Therefore, the first injection port 2- is also slightly moved back and forth with a stroke indicated by two points f1115 and a symbol S indicating distance, for example, a stroke of about 10 mm or less.

Therefore, by simply operating the micro-movement operation part S4 with your fingertips, you can remove dirt over a relatively wide area around your private parts without having to forcefully move your inconvenient body sitting on the toilet seat as in the past. It can be completely washed off.

In addition, during this fine movement operation, both the inner and outer cylinders 14 and 15 are reciprocated as one unit, so there is no problem of the cleaning point shifting, and the wear of the seal 1 is not accelerated. There is no problem such as water leakage between the cylinders 14°1S and a drop in the pressure of the cleaning water.

Then, when the fine movement operation section 54 is released, the electric motor 21 is stopped. Furthermore, when the pressure on the cleaning switch 52 is released, the timer circuit T operates to rotate the electric motor 27 in the reverse direction, and with the solenoid valve temporarily closed, the nozzle cylinder 3 removes the inner cylinder 15. While being housed in the cylinder 14, it is moved backward and returned to the starting position shown by the solid line in FIG. After completion of this return, the solenoid valve is reopened for only 2 to 3 seconds, during which time the re-injection port 21.21 is self-cleaned by hot water passing through the nozzle cleaning channel 25 as described above.

After that, the electric motor 27 is activated by an instruction from the timer circuit T1.
At the same time, the solenoid valve is closed by the solenoid valve opening/closing circuit.

Next, when performing bidet cleaning, the cleaning switch 52
If the bidet cleaning switch 53 is pressed instead, the bidet cleaning will be performed in the same manner as when the cleaning switch 52 is pressed.

However, in this case, as the rotating drum 5 rotates, the inner cylinder 15 is pushed out to the second forward position shown by the two-dot chain line in FIG. 1 and also shown in FIG.

Therefore, as understood from FIG. 7, the cleaning water that has flowed into the hot water inflow boat 17A is injected from the second injection port 21 through the water passage 22. Then, the pin 1 constituting the fine mover II7 is fitted into the pin groove 11 of the Geneva gear 12.

FIG. 9 shows another embodiment of the present invention, and the difference from the above embodiment lies in the configuration of the fine movement mechanism 7, that is, in this embodiment, the Geneva mechanism is rotated around a pin 30. Instead of the gear 12, a fan-shaped gear 41 rotated around the pin 30 is used, and instead of the bottle grooves 11, tooth parts 41A and 41B are provided at positions corresponding to these bottle grooves, On the other hand, the outer circumferential surface of the rotary drum 5 is provided with teeth 42A or 42B that mesh with the teeth 41A or 41B, respectively, at locations corresponding to the bins 8 and 3, and a connecting rod 43 in place of the connecting rod 13 is provided. This converts the rotational motion of the gear 4I into a reciprocating motion and transmits it to the nozzle tube 3.

The operation of this embodiment is objectively the same as that of the above embodiment, so a description thereof will be omitted.

In each of the above embodiments, the transmission member 6 is not limited to a band-shaped leaf spring, but may also be made of an elastic wire such as piano wire, a crank, etc., or by changing the detailed structure of the nozzle tube 3, Further, the movement stroke during the back and forth movement may be arbitrarily made variable.

Furthermore, two engaging bottles each were provided, ■, 9, bottle groove 1@,
11, tooth portions 41 A, 41 B, tooth portion 42A.

The object of the present invention can be achieved even if the design of each component is appropriately changed, such as by providing only one of the chairs 42B.

[Effects of the Invention] As is clear from the above explanation, the sanitary cleaning device according to the present invention has excellent practical effects as listed below.

(a) The control device installed in the sanitary washing device allows you to slightly move the position of the nozzle that sprays the washing water by simply operating the operating part of the fine movement mechanism, so when you want to thoroughly wash the surrounding private parts. In addition, this can be done easily and reliably without having to forcefully move the disabled body sitting on the toilet seat as in the past.

(b) Therefore, unlike in the past, there is no need for the cleaning water to scatter in unexpected places due to inappropriate and forceful movement of the body, and the usability is greatly improved.

(c) The fine movement mechanism is a simple gear mechanism or link I! Since it is simply constructed using an oval, the cleaning device can be made inexpensively and compactly.

(d) Since the forward and backward movement of the inner cylinder of the nozzle cylinder and the slight movement of the outer cylinder are performed by one electric motor, the sanitary cleaning device can be made extremely compact from this point of view as well. Can be provided at low cost.

(e) The inner and outer cylinders that make up the nozzle cylinder and which slide against each other are moved together when the nozzle cylinder is finely moved, which prevents wear of the packing material attached to both openings and closings, making it easier to clean. The devices can be used without mutual support for a long period of time.
