DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device for local washing attached to a Japanese-style toilet built into the floor of a toilet, and to a sanitary washing device therefor.
The present invention relates to a Japanese style toilet device provided with:

[0002]

2. Description of the Related Art A stool type Western-style toilet bowl can be provided with a warm water flush toilet seat having a flushing function for local flushing after stool. In this warm water flush toilet seat, a toilet seat that covers the toilet body is integrated into a casing, and local cleaning can be performed by a nozzle device incorporated in the casing.

[0003] In place of such a Western-style toilet, a Japanese-style toilet equipped with a hot water washing device for local washing is already known. As an example, there is one described in, for example, Japanese Patent Publication No. 5-13210.

In this system, a casing serving as a pair of footrests is arranged along the left and right sides of a toilet body built into the floor, and a functional part for washing with hot water is housed in one of the casings. It is configured to include a connected nozzle device. The nozzle device includes a cylinder and a nozzle rod housed in the cylinder, and stands by at a position where the nozzle rod retreats in the casing during stool use, and is supplied with cleaning hot water to the cylinder during cleaning. Then, the nozzle rod is advanced to the cleaning position using the water pressure generated by the supply of the cleaning water, and the cleaning is performed by jetting the cleaning water.

[0005]

In a hot water flush toilet seat provided on a stool type toilet, a person sits on the toilet seat while the nozzle sprays washing water from below the toilet seat, so the posture of sitting on the toilet seat is not appropriate. In such a case, only the vicinity of the buttocks is immersed in the washing water, and there is no great inconvenience in use.

On the other hand, in the case of the Japanese-style toilet described in the above-mentioned publication, the washing water from the tip of the nozzle rod scatters after hitting the human body. There is a high risk of reaching. For this reason, as described in the official gazette, the casing needs a means such as raising a rebound preventing wall for blocking the scattering of water.

However, since the casing itself is arranged outside the toilet body along the rim, the scattered water permeates between these rims and the casing. In addition, since the scattered water often contains even a small amount of sewage or filth, if it is still infiltrated, it emits an unpleasant odor and has a serious problem in terms of sanitation.

[0008] As described above, in the conventional structure, if the washing water rebounds to the outside of the toilet body, it cannot be recovered and cannot be treated except for natural drying. 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 and to collect it on the toilet side to maintain sanitary use and eliminate practical obstacles.

[0010]

SUMMARY OF THE INVENTION The present invention provides a toilet bowl
A casing that covers the

In the apparatus, the casing covers almost the entire area of the rim.
It is characterized in that it is configured in the shape of a circle .

In such a Japanese style toilet , the case
The part that covers the rim of the toilet bowl faces the bowl of the toilet bowl.
The splash water at the time of washing having a downward inclination is applied to the ball portion side.
And a surface on the collection surface.
A washing mechanism for washing off may be provided .

In the case of a Japanese-style toilet bowl, flush water is applied to the ball portion.
It is a water-wash type that can be supplied, and it is easy to clean the collection surface.

[0013]

[0014]

Since the casing for the local cleaning function is covered on the rim of the toilet body, even if water splashes during cleaning, it does not infiltrate the floor surface outside the rim. In addition, since the casing has a collecting surface that is inclined downward toward the bowl portion side of the toilet body, scattered water returns to the toilet side along this collecting surface and leaks to the floor side. Disappears.

Further, if water is supplied to the collecting surface to wash out this portion, it is possible to wash off splashing water which is likely to contain a small amount of sewage or filth.

Further, by arranging devices for driving and controlling the local washing / cleaning means and a valve mechanism for supplying washing water in a functional unit separate from the casing, the bulk of the casing is reduced. It becomes small, and the height rise in the height direction is small. In addition, the operation of toilet bowl ball cleaning
Activate the collection surface cleaning mechanism in conjunction with
This eliminates the need for a special operation for cleaning the collection surface.

Further, by providing the footrest portion in the casing, the position of the user's body can be matched with the position of washing by the local washing means incorporated in the casing, and the accuracy of washing can be improved.

FIG. 1 is an exploded perspective view showing an embodiment of a Japanese-style toilet with a washing function according to the present invention.

In the figure, a toilet body 1 assembled on the floor except for a rim portion 1a is a conventionally known flush-type Japanese toilet, and is used for supplying cleaning water for discharging sewage and filth from the ball portion 1b. Flash valve 1c is connected.

On the toilet body 1, a casing 2 of a local cleaning device having a substantially U-shaped planar shape covering the entire flat rim 1a is placed. Also, a functional unit 3 which is disposed separately from the casing 2 and in the vicinity thereof and houses a mechanism, a controller, and the like for operating the cleaning function.
Is provided.

FIG. 2 is a cutaway plan view when the casing 2 and the functional unit 3 are laid out on the toilet body 1.

The functional unit 3 is provided with a water supply pipe 3a connected to a water supply pipe of a building.
and a valve unit 3c having various valves for opening and closing the flow path and adjusting the flow rate. The water supply pipe 3a is connected to an auxiliary pipe 3d that branches before entering the heat exchanger 3b, and the auxiliary pipe 3d is connected to an on-off valve 3e using an electromagnetic valve.
Is provided. Further, a motor 3f with a speed reducer for moving a nozzle device (described later) forward and backward is provided, and a controller 3g for controlling each device is incorporated.

On the upper surface of the function unit 3, an operation switch in which operation switches of the respective function units are arranged is used. The operation switches include a washing switch 4a and a stop switch 4.
b, a hot water temperature setting switch 4c, a casing washing switch 4d, etc., and a water pressure adjusting knob 4e for operating a flow rate adjusting valve of the valve unit 3c.

The casing 2 is provided with a nozzle device at a portion located on the rear end side of the ball portion 1b. This nozzle device is provided with a nozzle main body 5 which is held by a guide sleeve 2a fixed to the casing 2 and is movable in the axial direction.

In order to move the nozzle body 5 in the axial direction, the nozzle unit 5 is connected to the motor 3f of the functional unit 3 by three link rods 6a, 6b, 6c. The link rods 6a to 6c allow the motor 3
In accordance with the forward and reverse rotation of the output shaft of FIG.
A reciprocating operation from the storage position indicated by the solid line in the middle to the washing position indicated by the dashed line is enabled.

The nozzle body 5 is connected to two cleaning water supply pipes 7a and 7b from the valve unit 3c as separate flow paths at the base end. These washing water supply pipes 7
Reference numerals a and 7b use a tube made of rubber or the like so as to follow the reciprocating operation of the nozzle body 5.

Further, on the left and right sides of the casing 2, there are integrally provided footrests 8a and 8b for placing the feet of the user. These footrests 8a and 8b have a flat shape with a certain amount of clearance when used by people of ordinary foot size, restrict a certain degree of freedom, determine the position of the body, and use a nozzle device. It has the function of keeping the washing point from shifting.

FIG. 3 is a schematic longitudinal sectional view showing the positional relationship between the casing 2 and the rim 1a of the toilet body 1 at the position seen from the line AA in FIG.

On the bottom surface of the casing 2, a concave portion 2b is provided along the entire length of the rim portion 1a of the toilet body 1 which slightly protrudes from the floor of the toilet and fits loosely from above. As shown in FIG. 1, the entire outer surface of the toilet body 1 facing the ball portion 1b except for the guide sleeve 2a is a collecting surface of the splashing water inclined downward toward the ball portion 1b. 2c.

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

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

The washing pipes 3d-1 and 3d-2 may be directly connected to one or more spreaders without providing the water supply chamber 2d.

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

The discharged washing water finally hits a local part and scatters around, a part of the water falls directly on the ball part 1 b, and a part adheres to the surface of the casing 2. Even if such washing water rebounds, 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 is provided as shown in the conventional example. There is no infiltration of splashing water along the area. Further, the water adhering to the surface of the casing 2 naturally flows down to the ball portion 1b due to the inclination of the collecting surface 2c, and draining is promoted.

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

By providing the spreader slit 2e on the collecting surface 2c in this manner, it is possible to collect and adhere to the ball portion 1b the adhering water which may contain a small amount of sewage and dirt. Surface dirt is eliminated.

If the flush water is discharged from the spreader slit 2e at the same time as the flushing operation of flushing the bowl portion 1b to discharge wastes and the like, the collecting surface 2c is always used after the toilet is used. Is washed out, so that more sanitary use is possible.

Further, 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 the components 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 bulk in the height direction, can be suppressed. Even when the casing 2 is put on the toilet body 1, the effect of raising the bulk is small and the usability is improved.
In addition, since the entire casing 2 has a flat shape, interference with the toilet door can be avoided, and there is no problem in incorporating the casing 2 into an existing toilet.

Further, the footrests 8a, 8
b, as described above, just by appropriately positioning the feet on the footrests 8a and 8b, the nozzles 5 can be flushed with the jet of washing water during washing. You can take a posture of the body. For this reason, the washing points can be accurately adjusted, and washing can be performed without unnecessary wetting of the buttocks and legs.

Here, the footrests 8a and 8b are fixed to the casing 2 by being fitted to each other instead of being integrally formed with the casing 2, and are fixed to the casing 2.
May be formed separately from the casing 2 as long as the positional relationship between them and the cleaning point is specified.

As a structure for preventing the splash of the washing water from going outside the rim 1a, for example, as shown in FIG. 4, an air chamber 2f is provided in a casing 2 located inside the rim 1a. Scattering can also be blocked by curtains.

In this case, for example, the water supply chamber 2d
Is provided below and a discharge slit 2g having a narrow opening cross section is opened downward. The air chamber 2f is connected by a duct to a blower fan (not shown) provided in the mechanism unit 3, and the rim unit 1a is operated by continuously operating the blower fan during the cleaning.
Creates an air curtain with strong airflow along the inner circumference of the. As a result, the splashing water that is going to the outside is shut off and collected on the ball portion 1b side, so that the infiltration of the scattered water on the floor surface outside the rim portion 1a is prevented.

[0044]

According to the present invention, the rim portion of the toilet body and its surroundings are hidden by using the casing in which the local cleaning means is incorporated, so that water splashes at the time of flushing occur at the boundary between the rim portion and the floor surface. A sanitary environment without infiltration and emission of off-flavors can be maintained.

Further, not only the splash water can be returned to the toilet side by the collecting surface, but also by attaching the washing water to the collecting surface, it is possible to wash off the adherence including the sewage and the like, thereby enabling clean use.

Further, if the functional unit is arranged separately,
It is only necessary to incorporate the local cleaning means and its piping system inside the casing, so that the bulk of the casing can be suppressed, and it can be easily accommodated in the existing toilet bowl.
