[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Japanese-style toilet attached to the floor of a toilet, and more particularly to the structure of a Japanese-style toilet having a local cleaning function for cleaning after toilet.

[0002]

2. Description of the Related Art A western style toilet seat can be equipped with a warm water washing toilet seat having a washing function for local washing after toilet. In this warm water washing toilet seat, a toilet seat that covers the toilet body is integrated with a casing, and a nozzle device built in this casing enables local washing.

In place of such a Western-style toilet bowl, a Japanese-style toilet bowl provided with a hot water washing device for local washing is already known. As an example thereof, there is one described in Japanese Patent Publication No. 5-13210.

This is to arrange a casing which also functions as a pair of footrests along the left and right sides of the toilet body built into the floor, and accommodates a functional part for washing with warm water in one of the casings, and also as a hot water supply source for this functional part. It is configured to include a connected nozzle device. The nozzle device includes a cylinder and a nozzle rod housed in the cylinder. The nozzle device stands by at a position where the nozzle rod is retracted in the casing at the time of use, and hot water is supplied to the cylinder at the time of cleaning. Then, the nozzle rod is advanced to the cleaning position by utilizing the water pressure supplied by the cleaning water, and the cleaning water is sprayed to perform the cleaning.

SUMMARY OF THE INVENTION In a warm water flush toilet seat equipped with a stool-type toilet bowl, while a person sits on the toilet seat, the nozzle sprays washing water from the lower side of the toilet seat, so the posture of sitting on the toilet seat is not appropriate. Even in such a case, only the buttocks are exposed to the washing water, and there is no great inconvenience in terms of usability.

On the other hand, in the case of the Japanese-style toilet bowl described in the above publication, the washing water from the tip of the nozzle rod splatters after hitting the human body, not only in the buttocks but around the legs and the rim of the toilet bowl. It is likely to reach For this reason, as described in the publication, the casing needs a means for raising such a bounce prevention wall for blocking the scattering of water.

However, since the casing itself is arranged along the rims of the toilet body outside thereof, the splashed water permeates between the rims and the casing. In addition, since scattered water often contains a small amount of sewage and dirt, if it continues to permeate, it may cause an offensive odor and pose a significant sanitary problem.

As described above, in the conventional structure, if the flush water bounces up to the outside of the toilet body, it cannot be recovered and there is no other way to treat it than to let it dry naturally. It will have a bad effect.

The problem to be solved in the present invention is to prevent splashing water at the time of washing from reaching the outside of the toilet bowl, and to collect it on the toilet bowl side to maintain hygienic use and eliminate practical obstacles.

[0010]

SUMMARY OF THE INVENTION The present invention is a Japanese style toilet provided with a local cleaning means capable of appearing and retracting from a casing attached to the toilet body of a Japanese style toward a rear portion of a ball portion of the toilet body. Has a bottom surface that covers the rim portion of the toilet body, and has a collecting surface that has a downward slope on the ball portion side of the toilet body and that guides splash water during cleaning to the ball portion side. Characterize.

In such a Japanese-style toilet, it is possible to provide a casing cleaning structure for draining the water supplied from the outside along the recovery surface.

A functional unit for accommodating a device for operating and controlling the local cleaning means and a valve mechanism for supplying cleaning water may be provided separately from the casing.

Further, the casing may be continuously provided with a footrest portion whose position is adapted to the washing point by the local washing means.

[0014]

Since the rim portion of the toilet body is covered with the casing for the local cleaning function, even if water splashes during cleaning, it is prevented from infiltrating the floor surface or the like outside the rim portion. Also, since the casing has a collecting surface that is inclined downward toward the ball portion side of the toilet body, the splashed water returns to the toilet side along this collecting surface and leaks to the floor side. Disappear.

Further, by supplying water to the recovery surface to wash away this portion, it is possible to wash off the splash water of the wash water which is likely to contain a small amount of dirty water, dirt and the like.

Further, the equipment for driving and controlling the local cleaning means, the valve mechanism for supplying the cleaning water, etc. are centrally arranged in a functional unit separate from the casing, so that the casing is small in volume. Therefore, it is possible to increase the height in a small amount.

Further, by providing the casing with the footrest, it is possible to match the washing position by the local washing means incorporated in the casing with the position of the person's body to improve the washing accuracy.

Further, in the nozzle body 5, two washing water supply pipes 7a and 7b from the valve unit 3c are connected to the base end as separate flow passage systems. These wash water supply pipes 7
The tubes a and 7b are made of rubber or the like so that they can follow the reciprocating motion of the nozzle body 5.

Further, on the left and right sides of the casing 2, foot rests 8a, 8b for placing the feet of a user are integrally provided. These foot rests 8a and 8b have a planar shape with a certain amount of room when used by a person with a normal foot size, and a certain degree of freedom is restrained to determine the position of the body. It has a role to prevent the cleaning point from shifting.

FIG. 3 is a schematic vertical cross-sectional view showing the positional relationship between the casing 2 and the rim portion 1a of the toilet body 1 taken along the line AA of FIG.

The bottom surface of the casing 2 is provided with a recess 2b over the entire length which fits gently into the rim portion 1a of the toilet body 1 slightly protruding from the floor of the toilet. In addition, as shown in FIG. 1, the entire outer surface of the toilet body 1 facing the ball portion 1b except the guide sleeve 2a has a downwardly inclined splashing water recovery surface toward the ball portion 1b side. 2c.

As shown in FIG. 3, a closed water supply chamber 2d is formed in a part of the recovery surface 2c corresponding to the left and right linear portions when viewed from the front. And two washing pipes 3d-1 and 3d-2 branched from the auxiliary pipe 3d are respectively connected to these water supply chambers 2d. Further, in order to discharge the cleaning water supplied to the water supply chamber 2d to the recovery surface 2c, a plurality of spreader slits 2e are cut and provided in the casing 2.

These spreader slits 2e are shown in FIG.
As shown in FIG. 5, the collection surface 2c is arranged in the front-rear direction. In order to make the flow along the recovery surface 2c, as shown in FIG. 3, the spreader slit 2e is obliquely downward in the cutting direction.

In the above structure, when the cleaning switch 4a is turned on, the motor 3f is actuated and the link rods 6a to 6a.
By the operation of c, the nozzle main body 5 advances to the position indicated by the alternate long and short dash line in FIG. 2 and stops, and hot water is discharged from the nozzle main body 5 to perform local cleaning.

The discharged cleaning water finally hits a local portion and scatters around, and a part thereof falls on the ball portion 1b as it is and a part adheres to the surface of the casing 2. Even if such washing water splashes, the rim 1a of the toilet body 1 is held in the recess 2b on the bottom surface of the casing 2, so that the rim 1a of the toilet body 1 as shown in the conventional example. Water does not infiltrate the area along the line. Further, the water attached to the surface of the casing 2 naturally flows down to the ball portion 1b side due to the inclination of the recovery surface 2c, and drainage is also promoted.

When the stop switch 4b is operated, the discharge of washing water from the nozzle body 5 is stopped and the casing 2
Retract to the storage position inside. If the recovery surface 2c of the casing 2 is soiled by the splashed water of the cleaning water, the casing cleaning switch 4d is turned on. As a result, the on-off valve 3e is opened and water is washed into the washing pipes 3d-1 and 3d-.
2 is supplied to the water supply chamber 2d, and is discharged from the spreader slit 2e onto the recovery surface 2c.

Since the spreader slit 2e is provided on the collecting surface 2c in this manner, the adhered water that may contain a small amount of dirty water and dirt can be flowed down to the side of the ball portion 1b and collected, and the casing 2 of the casing 2 can be collected. Surface dirt is eliminated.

If the flush water is discharged from the spreader slit 2e at the same time as the toilet flushing operation in which the flush water is poured into the ball portion 1b to discharge dirt and the like, the collecting surface 2c is always used after using the toilet bowl. Since it is washed away, even more hygienic use becomes possible.

Inside the casing 2, washing water supply pipes 7a and 7b to the nozzle body 5, washing pipes 3d-1 and 3d-2 to the water supply chamber 2d, and a link rod for operating the nozzle body 5 are provided. Only 6b and 6c are stored, and all other devices are arranged in the functional unit 3.

For this reason, the size of the casing 2, particularly the height thereof can be suppressed, and the effect of raising the size of the casing 2 even when it is put on the toilet body 1 is small and the usability is improved.
Further, since the entire casing 2 has a flat shape, it is possible to avoid interference with the toilet door, and there is no problem in assembling into the existing toilet bowl.

Furthermore, the casing 2 has footrests 8a, 8
Since b is integrally provided, as described above, it is possible to match the ejection of cleaning water by the nozzle body 5 at the time of cleaning simply by appropriately positioning the feet on the footrests 8a and 8b. It can take a physical posture. Therefore, the cleaning points can be accurately adjusted, and the cleaning can be performed without unnecessarily wetting the buttocks and legs.

Here, the foot rests 8a and 8b are fixed to the casing 2 by fitting with each other instead of being integrally formed with the casing 2.
It may be molded as a separate body from the casing 2 as long as the positional relationship with, that is, the cleaning point is specified.

As a structure for preventing the scattering of the washing water toward the outside of the rim portion 1a, an air chamber 2f is provided in the casing 2 located inside the rim portion 1a as shown in FIG. The curtain can also block the scattering.
