Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to measures for overflowing hot water in a unit bath room, and more particularly to the arrangement of drainage grooves formed in a waterproof pan.

[0002]

2. Description of the Related Art In recent years, so-called unit bath rooms have been widely used not only in condominiums and hotels but also in detached houses. The hot water that overflowed into the river never crosses this step. However, the unit bath room for the elderly is required to have a low step at the entrance and exit, which is required to be about 20 mm. On the other hand, in the unit bath room with the structure where the steps of the entrance and exit are improved as described above, when a person takes a bath at a stretch while the bathtub is filled with hot water, a large amount of hot water overflows from the bathtub. As a result, it will flow out very well. Further, since the height is about 20 mm, it may overstep the step and overflow to the dressing room side.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional technique, and appropriately blocks the momentum of the hot water overflowing from the bathtub even when the step of the door of the entrance / exit is low. It is an object of the present invention to provide a unit bath room that operates.

[0004]

The present invention has been made in order to achieve the above object, and is divided into a bathtub, a waterproof pan which is installed in the vicinity of the bathtub to form a washing space, and is divided into these. A unit bathru, comprising a wall panel enclosing a space and a ceiling panel fixed on the wall panel, wherein a drain groove is formed in a waterproof pan in parallel with a bath surface along the washing place. It is related to

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, the layout of drainage grooves in a waterproof pan is improved for hot water overflowing from a bathtub, and the hot water overflowing from the bathtub is directly received by the drainage grooves. As a result, the momentum of the hot water can be killed, and as a result, the momentum of the hot water reaching the entrance and the amount of hot water can be greatly reduced.

Generally, hot water overflowing from the bathtub falls along a parabola and falls to a place relatively far from the bathtub. That is, the hot water in the bathtub goes over the upper flange portion of the bathtub and falls on the waterproof pan, but the drainage groove described above is formed in this portion, and therefore the fallen hot water is in this drainage groove. It will slow down the momentum and will not get over the entrance of the waterproof pan, and in some cases the hot water that has overflowed to the entrance will not reach.

For this reason, the drainage groove is formed close to and along the surface of the bathtub on the side of the washing area. The width of this drainage port is preferably about 200 to 400 mm, and the depth is 3
If it is about 0 to 60 mm, it is convenient to kill the momentum of the overflowing hot water. It is preferable that a grating is fitted in the drainage groove. The grating may be made of stainless steel, but is preferably made of synthetic resin having a warm color, for example, ABS resin. It is preferable that the interstices are formed in a blind shape or a grid shape.

The falling point of the hot water overflowing depends on the shape of the tip of the flange portion of the bathtub. If the radius of curvature forming the tip of the flange portion is small, the hot water does not follow this curved surface and falls farther from the bathtub. . For this reason, it is necessary to make the drainage groove wide, which requires large grating. That is, when the radius of curvature forming the tip of the flange is small, it is almost irrelevant to the fall of the overflowing hot water, but by increasing this radius of curvature, the overflowing hot water flows along the curvature surface of the flange. It will flow down, and therefore will not fall to a position far away from the bathtub, and it becomes possible to control the dropping position of the hot water depending on the radius of curvature forming the tip of the flange portion. Therefore, the width of the drain groove can be made small, and in particular, the grating fitted therein can have a small width, which is advantageous in terms of cost.

As a result of the experiment, when the radius of curvature forming the flange of the bathtub is set to 20 to 50 mm, the hot water overflowing along this curvature surface falls, and at 20 mm or less, the effect is small, while When it is 50 mm or more, it is not desirable in terms of the appearance of the bathtub and the ease of grasping the edge of the bathtub.
