[Prior art]

 Conventionally, nozzles for sanitary washer of this kind have been shown in, for example, Japanese Utility Model Laid-Open No. 61-93571 and Japanese Utility Model Laid-Open No. 1-164370, but as shown in FIG. 4, there is an insertion guide opening 18b at the tip. A nozzle body 17 having a piston 17b is fitted and supported in a cylinder 18 to which a cylinder head 18a is attached so as to be movable back and forth. The spring A9 (coil spring) wound around the nozzle body 17 supports the piston 17b in the backward direction when it projects from the opening 18b, and the nozzle body 17 has a plug 17d at the tip opening. Is press-fitted and a jet port 17a is provided at the tip. A water supply port 18d and a water supply port 18c are provided at appropriate places before and after the cylinder 18, and a coil spring storage chamber formed between the cylinder 18 and the nozzle body 17 also serves as a cleaning water chamber on the outer peripheral surface of the nozzle or a hot water inlet of the piston 17b. 17c and the water supply port 18d can communicate with each other, and the water pressure chamber on the rear surface of the piston 17b and the water supply port 18c can communicate with each other. Further, the water supply port 18c and the water supply port 18d are connected by branching the water supply hose with the hot water tank, so that they can communicate with each other. Reference numeral 10 denotes a lid, which is attached so as to seal the rear end of the cylinder 18.

When an operation unit (not shown) is operated to wash an arbitrary local area after use in such a structure, the warm water tank, the water supply member 18d, and the water supply port 18d to the cylinder 18 can be operated. Water is sent to the hollow part. At this time, the hot water from the water supply port 18c becomes pressure water and is supplied to the hollow portion of the cylinder 18 which is sealed between the piston 17b and the lid 10. On the other hand, the pressure water from the water supply port 18d is supplied to the hollow portion between the piston 17b and the tip inside the cylinder 18, but leaks from the gap between the opening 18b and the side surface of the nozzle body 17. The pressure water from the water supply port 18c pushes the piston 17b to compress the spring A9, and the nozzle body 17 projects forward from the opening 18b.

Moreover, when the nozzle body 17 is completely projected, the water inlet 17c penetrating the piston 17b and communicating with the hollow portion of the nozzle body 17 coincides with the water outlet 18d, and the hot water from the hot water tank is discharged. The water is sent into the hollow portion of the nozzle body 17, and water is ejected from the ejection port 17a toward the local portion.

[0005]

[Problems to be solved by the device]

 In such a configuration, it is necessary to provide a plurality of water supply ports in the cleaning nozzle in the water passage from the hot water tank for producing the warm water for cleaning to the injection of the cleaning water, and the water passage branching member is required, which makes the structure complicated. There is a problem of becoming an expensive product.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above problems, and has a nozzle body having a jet end at the front end and protruding into the inside of the body during cleaning, and a cylinder head into which the nozzle body is inserted. The holding cylinder and the water supply port that communicates with the inside of the cylinder and the nozzle body are provided at the rear end of the side surface of the cylinder, and a lid is attached so as to seal the rear end of the cylinder. A nozzle lid having a push pin is provided, and a spring A for urging the nozzle body in the direction of retracting the nozzle body is provided in the front side of the cylinder, and a spring B for urging in the direction of pushing the nozzle lid is provided on the rear side of the cylinder. It is a thing.

[0007]

[Action]

 With the above configuration, at the start of cleaning, the warm water from the water supply port becomes pressure water to push the nozzle lid and the nozzle body, and the nozzle body is projected forward against the spring A. At this time, the nozzle B and the nozzle body are kept almost watertight by the spring B that urges the nozzle lid in the pushing direction. Next, when the nozzle body is completely projected, the push pin attached to the nozzle lid is pushed to the front end of the cylinder, the nozzle lid separates from the nozzle body, and a gap is created. It flows into the hollow part of the tank and spouts locally from the spout. When the washing is completed and the water supply is stopped, the pressure on the nozzle lid by the pressure water disappears and the spring A retracts the nozzle body.
