Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a cleaning nozzle in a sanitary cleaning device that is attached to a toilet bowl and is adapted to clean the private parts of the human body after using the toilet.

[Prior Art] The cleaning nozzle in a sanitary cleaning device is fixed in advance inside the toilet bowl, and as a result, it is easily soiled by urine and urine. In this type of device, which is designed to clean only a portion of the water, the cleaning nozzle and, by extension, the spout of the cleaning nozzle become dirty, which is extremely unsanitary.

[Summary of the invention]

The present invention has been made in view of the above, and an object of the present invention is to provide a cleaning nozzle for a sanitary cleaning device that is extremely hygienic and can effectively clean the cleaning nozzle, particularly the spout portion, in advance.

Examples of the invention] An embodiment of the present invention will be described below based on the accompanying drawings.

In the figure, 1 is a horizontally elongated main body, 2 and 3 are storage parts provided at the bottom of both ends of the main body, one storage part 2 stores a hot water tank 5 with a built-in heater 4, and the other storage part 3 houses a hot air generator. (not shown). Reference numeral 6 denotes a cleaning nozzle protruding from the central part of the front surface of the main body 1, and is connected to a hot water supply pipe T led out from the hot water tank 5, the detailed structure of which will be described later. Reference numeral 8 denotes a pump built into the main body 1, which is installed in the middle of a water supply pipe 10 that connects a water source, for example, a low tank 9 and a hot water tank 5. Reference numeral 11 denotes a toilet seat mounted on the front of the main body 1 so that it can be rotated by the range 12. Reference numerals 13 and 14 are control units provided on the upper surface of the main body 1 and located on the outside of the toilet seat 11, with a hot water temperature adjustment knob on one side. 15, the operation knob 16 of the pump 8,
A changeover switch 1T for the cleaning nozzle 6 is disposed, and a power switch 18 and a hot air fan operation switch 19 are disposed on the other side. Reference numeral 20 is a well-known Western-style toilet bowl, and the main body 1 is placed at the rear of the toilet bowl, the toilet seat 11 is placed on the toilet bowl, and the cleaning nozzle 6 is placed at a predetermined position inside the toilet bowl 20. Placed.

9 The cleaning nozzle 6 in the present invention has two cylinders 23 and 24 of different lengths connected to the hot water pipe 7 via a solenoid valve 21 and 22, and two cylinders 23 and 24 of different lengths inserted into each cylinder so as to be freely retractable. Two hollow nozzle bodies 25
．． It consists of 26. That is, the two cylinders 23, 24 have D-shaped through holes 27, 2 at their front ends.
The camp 29 with B) is integrally installed and has a connection port 30, 31 for the hot water pipe 7 at each rear end.
The caps 32 and 33 are fitted. On the other hand, the nozzle body 25 has the same cross-sectional shape as the through-hole 27.28, and is integrally formed with a flange 34 at the rear end having an outer diameter slightly smaller than the inner diameter of the cylinder 23.24. Further, the nozzle body 25 has a concave groove 35 formed on the upper surface thereof reaching the front end,
A spout 36 is formed at the front bottom of this groove. 31 is a stopper cylinder 3 fitted to the tip of the cylinder 23
The coil inserted between the nozzle body 8 and the collar 34 of the nozzle body 25 bounces to apply a force in the direction of inserting the nozzle body 25 into the cylinder. Reference numeral 39 denotes a date ring fitted into an annular step 40 provided on the outer periphery of the nozzle body 25, which contacts the stopper cylinder 38 with the nozzle body 25 protruding from the cylinder 23, and closes the gap between the nozzle body 25 and the cylinder 23. It is to be sealed watertight. Note that the other nozzle body 26 also has a four-tub structure.

The two nozzle bodies 25 and 26, the shorter one for cleaning the anus and the longer one for the bidet, project in parallel from each cylinder 23 and 24, and each spout 36
The anus cleaning nozzle body 25 is attached at a predetermined angle so as to face inward, thereby increasing the inclination of the anal cleaning nozzle body 25 inward.

In the above configuration, for example, when the selector switch 17 is set to anal cleansing, the solenoid valve 21 opens and at the same time the pump 8 is operated, water from the low tank 9 is sent to the hot water tank 5 via the water supply pipe 10, and the amount of water supplied is An amount of cleaning water equal to 1 is sent to the cylinder 23 via the hot water pipe I. cylinder 2
When the cleaning water enters the inside 3, the rear part of the nozzle body 25 is pushed by the water pressure, and the rolling ring 39 protrudes from the through hole 2T against the coil spring 31 until it comes into contact with the stopper cylinder 38. At this time, the cleaning water also flows into the gap between the cylinder 23 and the nozzle body 25 and flows through the groove 35 of the nozzle body 25 to its tip, so the cleaning water jetted from the spout 36 flows through the groove 35. Due to the washing water, the direction of the jet of water is tilted forward so that it does not reach the human body. When the nozzle body 25 protrudes to the maximum, that is, the ring 39
When it comes into contact with.

Since the gap between the cylinder 23 and the nozzle body 25 is sealed, the cleaning water is vigorously jetted out from the spout 36 and cleanses the anal region. If the pump 8f is stopped after cleaning, no water pressure will be applied to the nozzle body 25, so the nozzle body 2
5 is pulled back into the storage state within the cylinder 23 by the force of the coil spring 37. When the changeover switch 17 is set to the bidet, the bidet nozzle body 26 similarly protrudes from the cylinder 24 and performs the desired function.

〔Effect of the invention〕

Since the cleaning nozzle of the sanitary cleaning device according to the present invention has the above configuration, it is possible to clean the inside and outside of the nozzle body, especially the spout, before cleaning the private parts, making it hygienic and easy to use. The cold water that initially accumulated in the cylinder can be discharged without touching the human body, so it has excellent effects such as being comfortable to use at all times.
