Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage structure on a floor of a washing floor.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
As shown in the enlarged cross-sectional view of FIG. 5, a large number of concave grooves 4 are formed on the washing floor 1 toward the drainage box 2 side in a concavo-convex shape, and the drainage box 2 has a standing surface 2a, It is configured to have a perforated plate placing portion 2b, and the perforated plate 3 is placed on the perforated plate placing portion 2b. In the conventional case, the outer peripheral portion of the drainage box 2 is trimmed into a edging flat surface portion. 51 is formed.

In such a conventional drainage structure of the floor of the washing place, the water on the edging flat surface portion 51 first flows into the drainage box 2, so that it is guided to the recessed groove 4 to the drainage box 2 side. There is a problem that the flowing water is not continuous with the water on the edging flat surface portion 51, the flow of water in the concave groove 4 is cut, and a water pool is formed on the washing floor 1.

SUMMARY OF THE INVENTION The present invention has been devised in view of the above problems of the prior art, and it is possible to efficiently guide the water accumulated in the washing place to the drainage box and reduce the remaining water. With the purpose of not providing a drainage structure for the floor,
The first gist of the invention is that, in a washing-floor floor surface in which a large number of concave grooves for guiding drainage are formed toward a drainage box having a standing surface on the outer periphery of the perforated plate placing portion, each of the concave grooves is provided with the drainage. That is, it is formed so as to be continuous with the standing surface of the box and configured so that the water flowing through the groove flows into the drainage box without being broken. The second gist is that the downstream end of each groove is connected to the upper end of the standing surface of the drainage box in a rounded shape or an inclined shape.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the floor of the washing floor. On the bathtub (not shown) side of the floor 1 of the washing floor, a drainage box 2 is integrally formed in a concave shape. Is covered, and a water gradient is formed on the whole washing floor 1 toward the drainage box 2 side, and on the washing floor 1 there are a large number of concave grooves 4, 4 and 4 in a grid pattern on the drainage box 2. It is formed toward.

FIG. 2 shows an enlarged plan view of the vicinity of the drainage box 2 on the floor surface 1 of the washing place, and FIG. 3 shows a sectional view taken along the line AA of FIG. The drainage box 2 has a standing surface 2a that is substantially vertical to the outer peripheral side.
And a substantially horizontal plate 3 for mounting the plate 3 is formed on the inner side of the plate, and the plate 2 is further deeply recessed from the plate 2b for drainage. A drain port 2c is opened on the bottom side of 2.

In this example, as shown in the enlarged view of the main part of FIG. 4, the downstream end of each groove 4 forms a rounded portion 4a and is continuous with the upper end of the standing surface 2a. In addition,
The concave end of each groove 4 may be formed so as to be inclined and continuous to the upper end of the standing surface 2a. As described above, since each groove 4 is continuously formed on the standing surface 2a of the drainage box 2, the water flowing along the groove 4 can continuously flow into the standing surface 2a of the drainage box 2 without being cut. Will be possible.

That is, in the past, since the flat surface portion was formed on the outer peripheral side of the drainage box 2, the flow of water is blocked at this portion, and the water flowing through the concave groove 4 continuously flows into the drainage box 2. It could not be left, but in this example, the groove 4
Of water flowing through the rounded portion 4a and the standing surface 2a of the drainage box 2
The water flowing into the washing floor 1 can be efficiently guided to the drainage chamber 2 to be drained.
Less puddle formation on top.

Even when the floor surface 1 of the washroom is formed in an uneven pattern of rock surface, the recess for forming the rock surface is formed continuously toward the upper end of the standing surface 2a of the drainage box 2. If this is done, the water will not run off, and the water on the floor surface 1 of the washing place can be drained well to the drainage box 2.

[0010]

According to the present invention, each recessed groove is drained on the floor surface of the washing room in which a large number of recessed grooves for guiding drainage are formed toward the drainage box having a standing surface on the outer periphery of the perforated plate placing portion. Since it is formed so as to be continuous with the standing surface of the box and flows into the drainage box without cutting the water flowing through the groove, a large number of grooves are continuously formed on the standing surface of the drainage box. Therefore, the flow of water through the groove can be satisfactorily flown into the drainage box without being cut off, and the accumulated water in the washroom can be efficiently guided to the drainage box and drained, and the residual water on the floor of the washroom can be drained. There is an effect that can be extremely reduced.

Further, the downstream end of each groove is continuous with the upper end of the standing surface of the drainage box in a rounded or inclined shape, so that the downstream end of the recessed groove is connected to the upper end of the standing surface of the drainage box. It can be favorably continuously formed into a rounded shape or an inclined shape, and it is easy to continuously flow into the drainage cell without water being cut off, and the drainage efficiency can be improved.
