Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a nozzle for a sanitary washer, which is used for, for example, local washing after toilet.

2. Description of the Related Art Conventionally, nozzles for sanitary washer of this type have been disclosed in, for example,
As disclosed in Japanese Patent Publication No.-93571, a cleaning nozzle main body having a piston is fitted in and supported by a cleaning cylinder having a top cap having an insertion guide opening at its tip, so as to be movable back and forth,
A coil spring wound around the nozzle main body urges and supports the piston so as to project from the insertion guide port, and a jet outlet is provided at the tip of the nozzle main body. A port is provided in which the coil water storage chamber formed between the cleaning cylinder and the cleaning nozzle body and the cleaning water chamber on the outer peripheral surface of the nozzle, or the hot water inlet of the piston and the main water supply port can communicate with each other.
The water pressure chamber on the rear side of the piston and the auxiliary water supply port can communicate freely,
The main water supply port and the sub water supply port are not connected to each other, and a water supply hose for a hot water tank is branched and connected to the main water supply port and the sub water supply port.

The nozzle body of the structure according to the invention is made of, for example, a closed hollow metal member having a flat portion parallel to a required portion, and further, a coil spring wound around the nozzle body. When the force is generated and the water pressure projects from the insertion guide port, the nozzle body moves in the washing cylinder when biased by the coil spring in the winding direction of the coil spring as shown in FIG. There is a problem that the jet port formed in the above is slightly eccentric from the direction directly above the nozzle body, and the washing water does not reach the local part.

Means for Solving the Problems The present invention has been made in order to solve the above-mentioned problems, and includes a nozzle body that is provided at the front end portion with a nozzle and a rear portion with a piston, and a nozzle body that protrudes into the toilet body during cleaning. ,
A cylinder head that holds the nozzle body so that it can move back and forth, and that has a substantially oval-shaped opening at the tip of which the nozzle body is fitted, and a cylinder that has water supply ports A and B at a plurality of side surfaces. And a spring interposed so as to urge the nozzle body in a direction of retracting the nozzle body, and an inclination angle perpendicular to the opening is provided on both side walls of the opening.

By doing so, before the nozzle body projects into the toilet body, although the top portion of the nozzle body is slightly eccentric in the anti-winding direction of the spring, the nozzle body is When the protrusion is completed in the toilet body, the spring moves eccentrically in the winding direction of the spring by the angle of inclination described above, and in this state, the jet water spouting from the jet port spouts almost directly above the nozzle. .

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

In FIGS. 1, 2, 3, and 4 showing the configuration of the embodiment, 1 is a main body of a Western-style toilet bowl, and a water supply tank 2 and a hot water tank 3 are attached to the back thereof, and both tanks are provided. 2,
A water supply hose 4 that connects the two tanks 2 and 3 to each other is provided between the three. Reference numeral 8 denotes a cylinder, into which a nozzle main body 7 described later is fitted and which has side walls 8f and 8f provided with an inclination angle α with the vertical direction of the opening 8b, and which forms an almost oval-shaped opening 8b. The cylinder head 8a is provided with a water supply port A8d and a water supply port 8e at a plurality of side surfaces, and the vicinity of the tip is fixed above the rear part of the main body 1. Reference numeral 7 denotes, for example, a hollow sealed nozzle body made of a metal pipe or the like, which has a plug 7d press-fitted into the tip opening, a jet outlet 7a at the front end, and a piston 7b press-fitted into the rear opening.
In addition, a spring 9 for urging the nozzle body 7 in the direction of retracting the nozzle body 7 is provided between the piston 7b and the tip of the cylinder 8 via the spring 9.
It is held inside and out. 7c is a water inlet piston
It penetrates through 7b and communicates with the hollow portion of the nozzle body 7, and this water inlet 7c is a portion for sending hot water from the hot water tank 3 to the hollow portion when it coincides with the water inlet B8e 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 or the like, and connects the branch water feed port A6a and the branch water feed port B6b to the water feed port A8d and the water feed port B8e, respectively. ing. Reference numeral 10 denotes a lid, which is attached so as to seal the rear end of the cylinder 8.

When an operation unit (not shown) is operated to wash the local part after the toilet in such a structure, warm water through the branch pipe 6 is connected to the branch water supply port A6a and the branch water supply port B6b by the water supply member 5, respectively. Water is supplied to the hollow portion of the cylinder 8 from the water supply port A8d and the water supply port B8e. At this time, water outlet A8
The hot water from d becomes pressure water and is sent to the hollow portion of the cylinder 8 which is sealed between the piston 7b and the lid 10.

On the other hand, the pressure water from the water supply port B8e is supplied to the hollow portion between the piston 7b and the tip inside the cylinder 8, but leaks from the gap between the opening 8b and the side surface of the nozzle body 7. Further, the pressure water from the water supply port A8d presses the piston 7b to compress the spring 9, and the nozzle body 7 is projected forward from the opening 8b as shown in FIG. To do. At this time, as shown in FIG. 4, the nozzle main body 7 is eccentric via the side walls 8f and 8f following the certain inclination angle α, and the ejection port 7a is positioned almost directly above the nozzle main body 7.

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 supply port B8e, and the hot water from the hot water tank 3 is supplied to the nozzle body. It is sent to the hollow part of 7 and jets out the jetted water from the jet outlet 7a toward the local part.

Further, since the water inlet 7c is in close contact with the inside of the cylinder 8, most of the pressure water from the water inlet A8d and the water inlet B8e is hollow through the water inlet 7c during the projecting operation of the nozzle body 7. Does not penetrate into parts.

As described above, according to the present invention, the front end is provided with the ejection port and the rear is provided with the piston, and the nozzle main body that projects into the main body of the toilet at the time of cleaning, and the nozzle main body is held so that the nozzle main body can advance and retreat. A cylinder head having a substantially oval-shaped opening into which the nozzle body is inserted, a cylinder having water supply ports A and B at a plurality of side surfaces, and the nozzle body is biased in a retreating direction. By having a spring interposed as described above, and by providing a certain inclination angle with the vertical direction of the opening on both side walls of the opening, before the nozzle body projects into the toilet body, Although the top part of the nozzle body is slightly eccentric in the anti-winding direction of the spring, when the nozzle body completes projecting into the toilet body, it moves by eccentricity in the winding direction of the spring by the inclination angle. The spouted water spouting from the spouting port in this state spouts almost directly above the nozzle, and it is possible to provide a sanitary washing nozzle that reliably reaches the local area during washing.
