[0004]

In the above-mentioned conventional bathroom drainer, the lid plate is formed of a flat metal plate (stainless plate). On the other hand, tiles are usually attached to the floor of the bathroom. For this reason, there is a sense of discomfort in the design due to the difference between the tile surface and the drain cover plate (stainless steel plate) on the entire bathroom floor, and the location of the drain on the bathroom floor is particularly important. , It is not preferable because it results in emphasis. In addition, if a stainless steel lid plate is placed on the same surface as the bathroom floor, the bather may slip his feet on this lid plate, which is dangerous. There is a feeling of uncleanness due to the scale of the scale attached to the film, and cleaning is troublesome. That is, both the tile polishing agent and the stainless polishing agent (metal polishing agent) are required for cleaning, and the cleaning work is troublesome. Further, in the conventional drainage device, a separate trap projects downward from the bottom of the housing body. Therefore, the drainer itself becomes large, and the work of opening the prepared hole on the floor surface is troublesome, and there are disadvantages such that it is difficult to align the connection between the lower end of the trap and the sewer branch pipe.

The present invention solves the above problems and the drainer is designed and fused with the bathroom floor surface. As a result, the location of the drainer cannot be seen at first glance, and the drainer is installed on the floor surface. It is an object of the present invention to provide a bathroom drainer that is easy, small, and has no danger.

[0006]

In order to achieve this object, the bathroom drainer of the present invention has the following structure. A drainer for a bathroom is fixedly installed in a drainage hole on the floor of the bathroom, and is fitted and arranged with a base body with upper and lower openings that have a bearing surface portion in an appropriate position on the inner peripheral surface, and a fixed gap around this base body. It is characterized by comprising a rib leg portion supported on the support surface portion at an appropriate place on the lower surface, and a dish-shaped lid body having an upper portion for accommodating a tile for tiles similar to a bathroom floor tile.

In the bathroom drainer having such a structure, the same tile as a single tile forming the bathroom floor surface is attached and fixed to the accommodation portion of the dish-like lid. The tile surface in the dish-shaped lid is flush with the tile surface of the bathroom floor when the base body is fitted and attached to the floor surface drainage hole. Therefore, the bathroom floor surface becomes a unified tile surface including the lid part of the drainage device, and a total design structure can be realized.
In other words, in the bathroom, the viewer is not made aware of the existence of the drainage device at all. In addition, the tile surface of the drainer (dish-shaped lid plate) does not allow the bather to slip and fall, and the drainer uses a cleaning agent (tile polish) for cleaning the tiles on the bathroom floor. The tile surface of can be cleaned at the same time, separately,
No need for stainless steel polish. Further, since the wastewater on the floor surface is drained from the fitting gap between the frame of the base body and (the tile of) the plate-like lid, that is, the circumferential gap of the planar rectangular shape generated by the fitting, the amount of drainage is large and quick. High drainage efficiency can be obtained.

It is continuous at the top of the height. A groove portion 12b that is recessed downward is formed around the continuous portion. Further, a flat rectangular shaped stainless steel decorative frame body portion 14 having upper and lower openings is fitted in the groove portion 12b, and the decorative frame body portion 14 and the outer wall portion 1 are
1 and 1 are fixed by heat caulking 15. In this fitted state, the upper end of the decorative frame body portion 14 projects upward from the upper end of the outer wall portion 11. Further, at the upper end of the inner wall portion 12 (connection portion with the inclined wall portion 12a), a horizontal bearing surface portion 13 protruding inward is provided at a proper position (eight places in the embodiment). Further, a horizontal flange portion 16 is provided on the lower end portion of the outer wall portion 11 so as to project outward, and a plurality of vertical reinforcing ribs 17 are provided on the surface of the outer wall portion 11 so as to project outward.

The dish-shaped lid 2 is composed of a bottom plate portion 21 and a lid edge portion 22 fixed to the bottom plate portion 21 so as to be placed thereon.
The bottom plate portion 21 is made of a synthetic resin material (for example, ABS resin material), has a horizontal plate shape, and has a size to be mounted on the bearing surface portion 13. A plurality of reinforcing ribs (reinforcing ribs intersecting in the shape of "rice") 24 are provided on the bottom surface of the bottom plate portion 21 so as to project downward, and each reinforcing rib 24 has the highest height at the center of the bottom plate portion. Is set to a gradient (see FIGS. 2 and 3). Further, on the bottom surface of the bottom plate portion 21, the bearing surface portion 13 is
The rib leg portions (8 rib legs in the embodiment) 23 corresponding to the above are projected downward. The lid edge portion 22 is made of stainless steel and has a cross section "L" including a horizontal portion 22a and a vertical portion 22b.
It is formed in the shape of a frame with the upper and lower surfaces of the letter shape opened. The lid edge portion 22 is placed on the upper surface of the bottom plate portion 21, and the horizontal portion 22a
The overlapping portion between the outer peripheral portion of the bottom plate portion 21 and the outer peripheral portion of the bottom plate portion 21 is fixed by thermal caulking 26. As a result, the tile deployment accommodating portion 27 is formed, which has the bottom plate portion 21 as the bottom surface and is surrounded by the vertical portion 22b. Further, on the outer surfaces on both sides of the vertical portion 22b, there are attached lifting rotary plates 25 which are rotatably supported by pins 25a and which have openings 25b into which the fingertips are hooked and inserted. This dish-shaped lid 2 is used as a base body 1
And the rib leg 23 is supported by the support surface portion 13, the upper end of the vertical portion 22b and the upper end of the frame body portion 14 are at the same height, and the vertical portion 22b and the frame body portion 14 are
It is set so that a fitting gap (circle formed between fittings) C is formed. Further, in the accommodation portion 27 of the dish-shaped lid body 2, the same tile A as the single tile A constituting the bathroom floor surface is adhered and arranged via the mortar B. The floor tile A and the floor tile A are flush with each other (see FIGS. 2 and 3).

In the bathroom drainer having such a structure, a drainage pilot hole 3 is formed in advance on the floor surface as shown in FIG. 2, and the base body 1 is fitted into the pilot hole 3 and fixed by mortar. It In this fixed state, the upper surface of the tile A on the bathroom floor and the upper end of the frame portion 14 are flush with each other. On the other hand, in the in-plane accommodating portion 27 of the dish-shaped lid body 2, the same tile A as the tile A laid on the bathroom floor surface via the mortar B is used.
To accommodate and deploy. The dish-shaped lid body 2 provided with the tile A is fitted into the base body 1. The dish-shaped lid body 2 has rib legs 23.
Is mounted and fixed by being supported by the support surface portion 13. In this state, the upper end of the frame body portion 14 and the upper end of the lid edge portion (vertical portion 22b) 22 are flush with each other, and a circular drainage gap C is formed between the frame frame portion 14 and the vertical portion 22b.
The floor tile A and the tile A of the lid 2 are flush with each other. Therefore, the bathroom floor including the drain is entirely composed of the same tile A, and the above-mentioned drainage gap C
Corresponding to the joint between adjacent tiles A, the presence of the drainage device cannot be seen at first glance, and the drainage part is completely integrated with the bathroom floor surface to form a total design structure of the bathroom floor surface. (See FIG. 4).

Sewage on the floor of the bathroom is treated by the frame portion 14 and the lid edge portion 2.
It flows in from the fitting gap C with 2 and travels along the inclined wall portion 12a and the inner wall portion 12 and is directly drained to the drainage prepared hole 3, that is, the sewage branch pipe 4 provided below the drainage prepared hole 3. Therefore, sewage does not overflow into the upper surface of the drainage part (tile A) on the floor of the bathroom. In addition, since the wastewater is discharged from the circular gap C where the drainage ports are continuous, the drainage area is extremely large, the drainage is quick and the drainage efficiency is high. There is no feeling of filth. Even if filth collects in the drainage channel, by raising the rotating plate 25 located in the drainage gap C, the dish-shaped lid 2
Can be easily pulled out from the base body 1, and the inside can be easily cleaned.

In the embodiment, the cover edge portion 22 and the frame body portion 14 are made up of a decorative frame (made of stainless steel), but at the time of implementation, they are integrally made of the same synthetic resin material as the base body 1 and the bottom plate portion 21. The base body 1 and the bottom plate portion 21 including the lid edge portion 22 and the frame portion 14 may be integrally formed of stainless material.

[0015]

As described above, according to the present invention, the floor tile surface is formed within the thin vertical frame portion standing up from the bottom plate portion with respect to the thin plate decorative frame portion standing above the base body. Fit a dish-shaped lid with the same tile as the floor tile, and between the thin plate-shaped decorative frame part and the thin plate-shaped vertical frame part, between the vertical and horizontal floor tiles that make up the tile floor surface. Since the fitting gap for drainage that is continuous in a narrow width corresponding to the joint line is formed, the entire bathroom floor including the drain is made of the same tile. Further, with respect to the surface of the tile floor surface, the upper end of the decorative frame portion, the upper end of the vertical frame portion, and the tile surface in the vertical frame portion are all flush with each other. Moreover, there is no flange surface protruding horizontally in the upper part of the decorative frame part and the upper part of the vertical frame part. In other words, since it is just a thin plate-shaped enclosure, the tiles of the drainage device whose outer peripheral edge faces the vertical frame and the adjacent floors around the outside of the drainage device which faces the outer peripheral surface of the decorative frame body part. The tiles come into contact with each other only through a circular drainage gap. Therefore, there is no extra inclusion to be seen between the tile in the drainage device and the outer peripheral floor tile, except for the drainage gap, and the presence of the drainage device is more difficult to appear. Further, the drainage gaps that are continuous in a circle form a straight line corresponding to the vertical and horizontal joints between the vertical and horizontal floor tiles that form the tile floor surface. As a result, the presence of the drainage device in the drainage floor is combined with the above effect.
Completely assimilated and fused to the bathroom floor, the presence of a drainage device does not appear at first glance, and has the excellent effect of achieving the purpose of the invention.
