Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle for a sanitary washing machine which performs nozzle washing in addition to local washing.

[0002]

2. Description of the Related Art A conventional sanitary washer nozzle is shown in FIGS.
Shown in

In the figure, a cylinder 7 is provided with a piston 7b.
A nozzle body 7 having a nozzle is attached so as to be movable back and forth, a spring 9 for urging the nozzle body 7 toward the main water supply port 8d is attached, and a jet port 7a is provided at the tip of the nozzle body 7 so that The main water supply port 8d and the sub water supply port 8e are provided at appropriate places,
The washing water from the warm water tank 3 is branched and connected to the main water supply port 8d and the sub water supply port 8e via the branch pipe 6.

Further, when the auxiliary water supply port 8e is communicated with the gap 9a formed between the cylinder 8 and the nozzle body 7 and the operation part (not shown) is operated during the local cleaning, the cleaning water from the hot water tank 3 is supplied. The member 5 flows into the main water supply port 8d and the sub water supply port 8e through the branch pipe 6. The cleaning water from the main water supply port 8d becomes pressure water and pushes the nozzle body 7 forward, and the cleaning water from the sub water supply port 8e is a gap 9 on the outer peripheral surface of the nozzle.
The nozzle main body 7 which is drained from the opening 8b at the tip of the cylinder 8 via a and at the same time moves forward is washed. Further, when the nozzle body 7 is completely extruded, the sub water supply port 8e and the water inlet port 7c into the nozzle body 7 coincide with each other, and the wash water from the sub water supply port 8e is jetted locally from the jet port 7a. 61-93
571).

[0005]

In the conventional example, since the nozzle main body 7 that advances is washed with the washing water discharged from the opening 8b at the tip of the cylinder 8 at the initial stage of the local washing, the washing effect is insufficient. However, there is a problem that the user may have to directly clean the nozzle body 7.

There has also been a demand for the user to clean the nozzle body 7 itself at any time other than the local cleaning to make it sanitary. However, in the conventional example, the local cleaning and the nozzle cleaning cannot be performed separately, which is not convenient.

An object of the present invention is to clean the sanitary washer nozzle itself with a simple structure.

[0008]

In order to solve the problems, the present invention comprises a main body provided with a hot water tank, a water supply member for pressure-feeding the wash water of the hot water tank, and an ejection port for ejecting the wash water from the water supply member. It has a nozzle body with a piston and a water inlet in the front part, a cylinder that holds the nozzle body so that it can move back and forth, and a spring that urges the cylinder to retract the nozzle body. In a sanitary washer nozzle that sprays water locally, a main water supply port, a sub water supply port, and a nozzle cleaning water supply port are formed on the side of the cylinder, and a lid is provided at the rear of the cylinder. And the sub-water feed port and the water feed port communicate with each other when the nozzle body projects during local cleaning.

Further, a water passage direction valve for selectively supplying cleaning water is attached to the main water supply port, the sub water supply port, and the nozzle cleaning water supply port of the cylinder.

[0010]

In the above-mentioned sanitary washer nozzle, in addition to the conventional local washing, the nozzle body and the vicinity of the ejection port which are still accommodated in the cylinder at the time of washing the nozzle can be surely washed. Then, the dirty cleaning water is drained from the cylinder to the main body.

Further, the main water supply port of the cylinder, the sub water supply port, and the nozzle cleaning water supply port are equipped with the water flow direction valve for selectively supplying the cleaning water. Therefore, when the normal nozzle cleaning is selected, the water flow direction valve is used for cleaning. Since water is supplied to the nozzle cleaning water supply port to perform nozzle cleaning, local cleaning and nozzle cleaning can be performed separately.

Further, the waterway directional valve may be controlled so as to wash the local portion subsequent to the nozzle washing. In this case, not only the residual water in the branch pipe but also the residual water in the nozzle body is discharged during the nozzle washing. Therefore, cold water runs out during local cleaning, and only warm water of an appropriate temperature is ejected.

Reference numeral 2 denotes an operation portion, which is an operation button having a cleaning button 12a including a cleaning start button and a cleaning stop button and a cleaning button 12b, and is provided on the upper portion of the main body 1.

Next, the operation of the sanitary washer nozzle having the above structure will be described.

First, the operation unit 1 for cleaning the local area after the toilet is used.
When the second cleaning button 12a is operated, the cleaning water pressure-fed by the water supply member 5 flows into the waterway direction valve 11. Then, the waterway directional valve 11 is controlled by the output of the control unit (not shown) based on the operation of the operation unit 12 so that the main water pipe 6a and the sub water pipe 6b.
The cleaning water is supplied to the main water supply port 8d and the sub water supply port 8e of the cylinder 8 via the. The cleaning water from the main water supply port 8d is supplied to the hollow portion 8g of the cylinder 8. At this time, the washing water becomes pressure water and is sent to the hollow portion 8g of the cylinder 8 which is sealed between the piston 7b and the lid 10. Therefore, the main water supply port 8
The pressure water from d compresses the spring 9 and causes the nozzle body 7 to project forward from the opening 8b at the tip of the cylinder head 8a. When the nozzle body 7 has completely projected as shown in FIG. 3, the water inlet 7 communicating with the hollow portion 7e of the nozzle body 7
Since c is in communication with the sub water supply port 8e, the cleaning water is sent to the hollow portion 7e of the nozzle body 7, and the cleaning water is ejected from the ejection port 7a toward the local portion. Further, since the water inlet 7c is in close contact with the inside of the cylinder 8, most of the pressure water from the main water supply port 8d enters the hollow portion 7e of the nozzle body 7 through the water inlet 7c during the projecting operation of the nozzle body 7. Do not invade.

During nozzle cleaning, when the cleaning button 12b of the operating portion 12 is operated during normal operation (non-cleaning), the cleaning water pumped by the water supply member 5 flows into the waterway direction valve 11. Then, the waterway direction valve 11 causes the nozzle cleaning water supply pipe 6 to be operated by the output of the controller based on the operation of the cleaning button 12b.
Cleaning water is supplied to the nozzle cleaning water supply port 8f via c.
Since the water inlet 7c communicating with the hollow portion 7e of the nozzle body 7 communicates with the nozzle washing water supply port 8f of the cylinder 8, the washing water is sent to the hollow portion 7e of the nozzle body 7 and ejected from the jet port 7a. The ejected water hitting the cylinder head 8a can reliably clean the vicinity of the nozzle body 7 and the ejection port 7a which are still stored in the cylinder 8. Then, the dirty cleaning water is drained from the cylinder head 8a to the main body 1.

Further, the waterway direction valve 11 may be controlled so as to perform local cleaning after nozzle cleaning. In this case, not only the residual water in the branch pipe 6 but also the residual water in the nozzle body 7 is discharged at the time of cleaning the nozzle. As a result, the cold water runs out during the local cleaning, and only the proper temperature of cleaning water is ejected.

[0020]

In addition to the conventional local cleaning, the sanitary cleaning nozzle of the present invention can surely clean the nozzle body and the vicinity of the ejection port which are still stored in the cylinder during the nozzle cleaning.

Further, since the main water supply port, the sub water supply port, and the nozzle cleaning water supply port of the cylinder are equipped with the waterway direction valve for selectively supplying the cleaning water, when the normal nozzle cleaning is selected, the cleaning is performed via the waterway direction valve. Since water is supplied to the nozzle cleaning water supply port to perform nozzle cleaning, local cleaning and nozzle cleaning can be performed separately.

Therefore, it is possible to provide a sanitary washer nozzle which is hygienic and easy to use.
