[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to, for example, a nozzle for a sanitary washer used for local cleaning after toilet.

[0002]

[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 8 to which a cylinder head 18a is attached so as to be movable back and forth. Then, the spring 9 (coil spring) wound around the nozzle body 17 biases and supports the piston 17b so as to retract from the opening 18b, and the nozzle body 17 has a stopper 17d press-fitted into the opening at the tip end thereof. A jet port 17a is provided at the tip. A water supply port 8d and a water supply port 8c are provided at appropriate places before and after the cylinder 8, and a washing water chamber for the coil spring storage chamber and the nozzle outer peripheral surface formed between the cylinder 8 and the nozzle body 17 or hot water for the piston 17b. The introduction port 17c and the water feed port 8d are not communicable, and the water pressure chamber on the rear surface of the piston 17b and the water feed port 8c are communicable. Further, a water supply hose for the hot water tank is branched and connected to the water supply port 8c and the water supply port 8d 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 8.

[0003] In such a structure, when an operation section (not shown) is operated to wash an arbitrary local area after use, a hot water tank, a water feeding member, a water feeding port 8c, and a water feeding port 8d Water is sent to the hollow part. At this time, the hot water from the water supply port 8c becomes pressure water and is supplied to the hollow portion of the cylinder 8 which is sealed between the piston 17b and the lid 10. On the other hand, the pressure water from the water supply port 8d is supplied to the hollow portion between the piston 17b and the tip inside the cylinder 8, but leaks from the gap between the opening 18b and the side surface of the nozzle body 17. Further, the pressure water from the water supply port 8c pushes the piston 17b to compress the spring 9, and the nozzle body 17 projects forward from the opening 18b.

Moreover, when the nozzle body 17 is completely projected, the water inlet 17c which penetrates the piston 17b and communicates with the hollow portion of the nozzle body 17 coincides with the water outlet 8d, and the hot water from the hot water tank is discharged. Water is spouted into the hollow part of the nozzle body 17 and spouts water toward the local part from the spout 17a, but at the start of washing, cold water stays in the water passage from the warm water tank to the nozzle body 17 through the water supply member to the nozzle body 17. There is water, and the temperature becomes lower in winter and the cold water is sprayed initially.

[0005]

[Problems to be solved by the device]

 In such a configuration, the washing water is always accumulated in the water passage from the hot water tank for producing the hot water for washing to the injection of the washing water, that is, the hot water tank, the water feeding member, the water feeding member, the washing nozzle, and the washing nozzle. The water temperature of the accumulated water decreases with time after use, and the next time it is used, this cold water is pushed out and jetted at the beginning of use, which is extremely uncomfortable.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and a front end of the front end is provided with an opening B in the center and a hemispherical inner wall as a stopper, and a rear side is provided with a jet outlet. A nozzle body that has a ball on the front side between the opening B and the ejection port and a partition on the back side, and a piston at the rear portion that is higher than the front end portion and that projects into the body during cleaning, and a cylinder head into which the nozzle body is inserted And the cylinder that holds this, and the water supply ports that communicate with the inside of the cylinder and the nozzle body at the rear end and the front end of the side surface of the cylinder, respectively. It is provided with a spring.

[0007]

[Action]

 With the above configuration, at the start of use, water is sent into the cylinder through the water supply port at the rear end, pushes the piston, and advances the nozzle body against the spring, and at the time of use, the nozzle is discharged from the water supply port at the front end. Since the sphere is pushed out along the inner wall of the hemisphere of the stopper by water pressure of the wash water sent to the main body and the opening B is closed in a watertight manner, the wash water is sprayed only from the jet port. After the end of use, the water pressure is no longer applied, the injection of washing water is stopped, the ball moves to the partition side and opens the opening B, and the nozzle body is retracted inward by the spring. Since the rear part is located higher than the front end part and there is a water level difference in the nozzle body as well, there are two openings, the jet port and the opening B, which makes it possible to replace it with air and drain the water from the opening B. The water is drained not only from the nozzle body, but also from the entire canal that is hermetically connected.
