Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a sanitary cleaning device that can clean private parts hygienically and comfortably, and in particular, a nozzle head portion of a telescopic nozzle that spouts cleaning water. It relates to a mechanism for cleaning before and after use.

(Prior Art) Conventionally, a sanitary washing device for washing private parts of the human body has been proposed in which a nozzle for spraying washing water is extendably provided on the underside of a toilet seat. This telescopic nozzle is arranged to face the direction of the toilet bowl, and when in use, is configured to extend to a position close to the private parts of the human body and spray hot water from its spout to clean the private parts. However, in the stored position, the nozzle head portion was exposed to the outside from the tip of the nozzle body.

(Problem to be Solved by the Invention) Therefore, when using the telescopic nozzle, and even when the telescopic nozzle is housed in the nozzle body fixed to the rear side of the toilet bowl, the nozzle body is constantly affected by splashing of sewage or direct liquid bath. The tip of the retractable nozzle and the nozzle head of the retractable nozzle become contaminated, and the dirt solidifies inside the retractable nozzle's nozzle, not only causing malfunctions such as jetting problems, but also causing foul odors and cleaning water that should be clean. There was a problem that the nozzle was contaminated by sewage and dirt accumulated in the nozzle area.The present invention improves this problem, and its purpose is to improve the storage position of the retractable nozzle. In this case, the nozzle head part is completely inserted into the nozzle body, and the nozzle head part is once protruded and stopped in front of the nozzle body before and after using the sanitary cleaning device, so that it is always used in a clean state. The goal is to make it possible.

(Means for Solving the Problems) As shown in FIGS. 1 to 6 of the embodiment drawings, the present invention provides a nozzle head portion 2c of a telescopic nozzle 2 in which ejection holes 2b and 2g are formed. is formed to be flatter than other parts, and the telescopic nozzle 2 is constructed to be completely housed within the nozzle body 1, and in this state, the inside of the nozzle body 1 corresponding to the front and rear portions of the nozzle head portion 2c is A packing 3 such as a Y-shaped cross section is interposed, and the nozzle head portion 2 is
An annular flow path 1a is formed through which cleaning water is discharged from the tip of the nozzle body 1 into the toilet bowl 9 via a pipe c, and this annular flow path 1a is communicated with a hot water storage tank through a connecting pipe 4 to perform sanitary cleaning. The nozzle head portion 2C is configured to protrude and stop outside the nozzle body 1 within the range necessary for cleaning before and after using the device.

(Function) When the cleaning start switch 11 arranged on the operation panel 10 is turned on to start anal cleaning or bidet cleaning, the telescopic nozzle 2 stops at a predetermined nozzle cleaning position S3 suitable for cleaning the nozzle head portion.

At this position, a solenoid valve or a solenoid pump operates for a short time, and cleaning water is supplied from the hot water tank through the connecting pipe 4 into the annular flow path la formed in the nozzle head portion 2C of the telescopic nozzle 2. This washing water is discharged into the toilet bowl while washing the nozzle head part and the tip part of the nozzle body 1 by its water pressure.

When the stop switch 12 disposed on the operation panel 10 is turned on, the telescopic nozzle 2 moves backward and stops at the nozzle cleaning position S3. Immediately after this, the solenoid valve or electromagnetic pump operates for a short time, and cleaning water is supplied from the hot water tank to the annular flow path la through the connecting pipe 4, and the nozzle head portion 2C of the telescopic nozzle 2 and the tip portion of the nozzle body 1 are is discharged into the toilet bowl 9 of the toilet bowl 8 while being cleaned. The telescopic nozzle 2 is housed within the nozzle body 1 after cleaning is completed.

(Example) Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

In the drawing, 1 is a nozzle body constituting a nozzle device A of a sanitary cleaning device, 2 is fitted into this nozzle body 1,
It is a telescopic nozzle that can move in and out from its tip and expand and contract.

This telescopic nozzle 2 has a double structure consisting of a hollow tubular outer cylinder 2a and an inner cylinder 2b extending concentrically within this outer cylinder 2a. A first flow path 2d that reaches the tip of the outer cylinder 2a, that is, the nozzle head portion 2C via the inner cylinder 2b, and a second flow path 2e that also reaches the nozzle head portion 2C via the outside of the inner cylinder 2b are formed. The upper surface of the nozzle head portion 2c where the first flow path 2d and the second flow path 2e terminate can obtain water force suitable for anal cleaning or bidet cleaning, respectively.
For example, a 3-hole or 5-hole first ejection hole 2f and second ejection hole 2g
is drilled. This nozzle head portion 2C is formed flat with a step 2h so that the nozzle head portion 2C is smaller in the vertical direction than other portions.

On the other hand, inside the tip of the nozzle body 1, a packing 3.3 having a Y-shaped cross section is arranged so as to sandwich the nozzle head portion 2C with the telescopic nozzle 2 completely housed. An annular flow path 1a is formed between the step portion 2h of the nozzle head portion 2C and the step portion 2h of the nozzle head portion 2C. This annular flow path 1a is a first flow path 2d or a second flow path 2e on the side of the expandable nozzle 2 in response to the expansion and contraction movement of the expandable nozzle 2.
It also 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 connected to the outside thereof. The elbow 5 is integrally connected and communicates with the flow path 5a passing through in the center direction.

The nozzle device A configured as described above is fixed in the casing 6 via the machine frame 7 and directed into the toilet bowl 9 of the toilet bowl 8. Further, the operation of jetting cleaning water from the nozzle device A is performed by a cleaning start switch 11 or a stop switch 12 provided on the operation panel 10. The stop position of the telescopic nozzle 2 is the first stop position S corresponding to anal cleaning and bidet cleaning.
1 and a second stop position S2 are set, 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 activated or stopped. The system is configured so that hot water supply is controlled by

In the above configuration, the operating time of the solenoid valve or the electromagnetic pump is immediately after the telescopic nozzle 2 stops at a predetermined nozzle cleaning position S3 suitable for cleaning, and immediately after retracting to the nozzle body 1 side and stopping at the cleaning position S3. Set it to a short time. This operating time is based on the nozzle head portion 2 of the telescopic nozzle 2.
1 within the range necessary for cleaning C and the tip of the nozzle body 1.
A short period of time such as seconds to several seconds may be sufficient.

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 l also has a Y It is not necessary to have a U-shaped cross section, for example, the packing may have a U-shaped cross section.

When operating the front and rear cleaning mechanism according to the present invention, the telescopic nozzle 2
When the nozzle head portion 2c is stopped at the nozzle cleaning position S3, the nozzle head portion 2c escapes to the outside of the packing 3.3 as shown in FIG. 4, and the stepped portion 2h communicates with the outside air. Therefore, the pressure of the flushing water is reduced at the step 2h, and its flow velocity is slowed down, so that the flying distance of the flushing water into the toilet bowl 9 is shortened, and splashing of droplets to the outside of the toilet bowl 8 is prevented.

(Effects of the Invention) Since 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.
By supplying cleaning water into the annular flow path of the nozzle body, dirty water or dirt adhering to the nozzle head portion of the telescopic nozzle and the tip portion of the nozzle body 1 can be cleaned. In addition, in the last-minute cleaning, the cold water 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.

In addition, immediate cleaning has an excellent effect in that dirty water or dirt can be washed off before it adheres to the nozzle head, and causes of malfunctions such as ejection failure can be removed.
