〔Example〕

Hereinafter, preferred embodiments of the front and rear cleaning device according to the present invention will be described with reference to the drawings.

In the drawings, 1 is a nozzle body constituting a nozzle device A of a sanitary cleaning device, and 2 is this nozzle body 1.
The nozzle is a telescopic nozzle that is fitted into the nozzle body 1, moves in and out freely from its tip, and is configured to extend and retract, and to be completely housed within the nozzle body 1 when not in use.

This telescopic nozzle 2 includes a hollow tubular outer cylinder 2a,
It has a double structure consisting of an inner tube 2b extending concentrically into the outer tube 2a, and depending on how well they fit together, the tip of the outer tube 2a passes through the inner tube 2b.
That is, the first flow path 2d reaches the nozzle head portion 2c.
A second flow path 2e is formed which also reaches the nozzle head portion 2c via the outside of the inner cylinder 2b, and the nozzle head portion where the first flow path 2d and the second flow path 2e terminate. On the upper surface of the body 2c, there are formed a first spout hole 2f and a second spout hole 2g, for example, three or five holes, which provide a water force suitable for anal cleansing or bidet cleansing, respectively. This nozzle head portion 2c is formed flat with a step 2h that is smaller in the vertical direction than other portions.

On the other hand, gaskets 3, 3 having a Y-shaped cross section are arranged inside the tip portion of the nozzle body 1 so as to sandwich the nozzle head portion 2c with the telescopic nozzle 2 fully housed. An annular flow path 1a is formed between the nozzle head portion 2c and the stepped portion 2h of the nozzle head portion 2c. This annular flow path 1a is a first flow path 2d or a second flow path 2 on the side of the expandable nozzle 2 in response to the expansion and contraction movement of the expandable nozzle 2.
e, and serves as a flow path for supplying cleaning water to the expandable nozzle 2 side, and a connecting pipe 4 for supplying cleaning water from a hot water source (not shown) on the heat exchanger side is provided on the outside thereof. The connecting elbows 5 are integrally connected and communicate with the flow path 5a extending in the center direction.

The nozzle position A configured as described above is fixed in the casing 6 via the machine frame 7, and the toilet bowl 9 of the toilet bowl 8 is fixed.
direct inward. Further, the operation of jetting cleaning water from the nozzle position A is performed by a cleaning start switch 11 or a stop switch 12 provided on the operation panel 10. The stop positions of this telescopic nozzle 2 are set as a first stop position S1 and a second stop position S2 corresponding to anal cleaning and bidet cleaning, and in the present invention, a nozzle cleaning position S3 is added to these. .

The method of supplying cleaning water from the hot water supply source is the same as in conventional systems; when using the so-called direct water supply method, the solenoid valve is opened, and when using the indirect water supply method, the solenoid pump is operated. Alternatively, the hot water supply is controlled by stopping the system.

In the above configuration, the operating time of the solenoid valve or electromagnetic pump is immediately after the telescopic nozzle 2 stops at a predetermined nozzle cleaning position S3 suitable for cleaning, and immediately after moving backward toward the nozzle body 1 and stopping at the cleaning position S3. Set to a short period of time. This operation time may be as short as one to several seconds within the range necessary for cleaning the nozzle head portion 2c of the telescopic nozzle 2 and the tip portion of the nozzle body 1.

Note that the structure of the telescopic nozzle 2 does not necessarily have to be the two-channel configuration for anal cleaning and bidet cleaning as described above, and the gasket defining the annular channel 1a in the nozzle body 1 also has a It is not necessary to have a U-shaped cross section, for example, the packing may have a U-shaped cross section.

When the front and rear cleaning device according to the present invention operates, when the telescopic nozzle 2 is stopped at the nozzle cleaning position S3, the nozzle head portion 2c escapes to the outside of the packings 3, 3, as shown in FIG. However, the stepped portion 2h communicates with the outside air side. Therefore, the pressure of the flushing water is reduced at the step 2h, and its flow velocity is slowed down, so that the distance of the flushing water flowing into the toilet bowl 9 is shortened, and splashing of droplets to the outside of the toilet bowl 8 is prevented.

〔Effect of the invention〕

Since the front and back cleaning device according to the present invention is configured as described above, by turning on the cleaning start switch or stop switch, the solenoid valve or the solenoid pump is operated before and after the telescopic movement of the telescopic nozzle, and the nozzle main body is By supplying cleaning water into the annular flow path of the extensible nozzle, it is possible to clean dirty water or dirt adhering to the nozzle head portion and the tip portion of the nozzle body.

In addition, in the last-minute cleaning, the cold water that has accumulated in the connecting pipe connecting the hot water storage tank and the nozzle device is removed, and by pre-wetting the packing, the sliding friction resistance of the expandable nozzle can be reduced, and the service life of the packing can be extended. .

Furthermore, immediate cleaning has the advantage of being able to wash off dirty water or dirt before it adheres to the nozzle head, thereby eliminating the cause of malfunctions such as ejection failure.
