 The present invention has been made in order to solve the above problems, and has a nozzle main body that has a jet outlet at the front end and a piston at the rear end, and that projects into the main body during cleaning and a cylinder into which this nozzle main body is inserted. The head has a head, and water supply ports communicating with the inside of the cylinder and the nozzle body are provided at two positions on the side surface of the cylinder that holds the head, and springs are provided inside the cylinder to urge the nozzle body in the direction of retracting. A drive member consisting of an electric element such as a solenoid is provided on the lid that is attached so that the rear end of the nozzle is tightly closed.At the start of cleaning, the nozzle body is retracted, and when the warm water from the hot water tank reaches The piston was pushed so that the nozzle body was projected inside the body.

[0005]

[Action]

 With the above structure, when cleaning starts, there is cold accumulated water in the nozzle body, and low-pressure cold water enters the nozzle body from the water supply port, but the nozzle body has not yet protruded into the body and the jet outlet Since it is retracted, cold water is drained from the gap between the fitting part of the nozzle body and the cylinder head and the jet outlet, and when hot water from the hot water tank arrives, the piston is pushed by the driving member to resist the nozzle body against the spring. It moves forward and sprays warm wash water locally from the jet.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2 showing the configuration, reference numeral 1 is a main body of a Western-style toilet bowl, and a water tank 2 and a hot water tank 3 are attached to the back of the body, and water tanks for communicating between the tanks 2 and 3 are provided. A hose 4 is provided. Reference numeral 8 denotes a cylinder, into which a nozzle main body 7 to be described later is inserted, a cylinder head 8a having a substantially oval-shaped opening 8b at its tip, and water supply ports 8c and 8d at a plurality of side surfaces. The vicinity of the tip is fixed above the rear of the main body 1.

Reference numeral 7 is a hollow sealed nozzle body made of, for example, a metal pipe. The nozzle body 7 has a stopper 7d press-fitted into the opening at the tip, a jet outlet 7a at the front end, and a piston 7b at the opening at the rear, and the nozzle body 7 is located between the piston 7b and the tip inside the cylinder 8. A spring 9 for urging the nozzle body 7 in the backward direction is interposed, and the nozzle body 7 is held in the cylinder 8 via the spring 9 so as to be movable back and forth. The water inlet 7c penetrates the piston 7b and communicates with the hollow portion of the nozzle body 7, and the water inlet 7c is a portion for sending hot water from the hot water tank 3 to the hollow portion during cleaning. A branch pipe 6 is provided between the warm water tank 3 and the cylinder 8 via a water feed member (for example, an electromagnetic pump) 5, and connects the branch water feed port 6a and the branch water feed port 6b to the water feed port 8c and the water feed port 8d. ing. Reference numeral 10 denotes a lid, which is attached so as to seal the rear end of the cylinder 8. The lid 10 is provided with a driving member 11 composed of an armature such as a solenoid.

Next, the operation of the above configuration will be described.

When an operation unit (not shown) is operated to wash an arbitrary local area after use, the water passage from the warm water tank 3 to the nozzle main body 7 through the water supply member 5 and the nozzle main body 7 at the start of cleaning in winter etc. There is cold accumulated water inside, and low-pressure cold water enters the nozzle body 7 from the water supply port 8d, but since the nozzle body 7 has not yet projected into the body 1, the opening 8b of the cylinder head 8a and the nozzle body Cold water is drained from the gap between the side surface of 7 and the jet outlet 7a, and when hot water from the hot water tank 3 arrives, the drive member 11 pushes out the piston 7b. The warm water through the branch pipe 6 is fed by the water feed member 5 to the hollow portion of the cylinder 8 from the water feed ports 8c and 8d connected to the branch water feed port 6a and the branch water feed port 6b, respectively. On the other hand, the pressure water from the water supply port 8d leaks from the gap between the piston 7b and the tip inside the cylinder 8. The piston 7b is pushed by the pressure water from the water supply port 8c to compress the spring 9 and the nozzle body 7 is projected forward from the opening 8b.

Moreover, when the nozzle body 7 is completely projected, the water inlet 7c penetrating the piston 7b and communicating with the hollow portion of the nozzle body 7 coincides with the water outlet 8d, and the hot water tank 3 Since the hot water is sent to the hollow part of the nozzle body 7, the nozzle body 7 is pushed out, the spring 9 is compressed, and the hot water from the hot water tank 3 passes through the hollow part of the nozzle body 7 and is directed from the jet outlet 7a to an arbitrary local area. Spout water.

Further, since the water inlet port 7c is in close contact with the inside of the cylinder 8, almost all the pressure water from the water inlet port 8c enters the hollow portion of the nozzle body 7 through the water inlet port 7c during the projecting operation of the nozzle body 7. Do not invade.
