Abstract

PROBLEM TO BE SOLVED: To obtain high drainage performance by inclining each drain gutter formed at a washing place section tilted towards a drain port at angles larger than the angles of inclination of the installation of a surface working section or a surface plate of a washing place body. SOLUTION: In the drainage structure of a unit bath by a waterproof pan 5 integrally molded of FRPs, etc., the grade of a gutter section 2 is made larger than that of a rift-like section 1 constituting a surface working section. In the gutter section 2, an upstream section separated from a drain inlet 4 is formed in shallow depth and a downstream section near to the drain inlet 4 in deep depth, and the gutter section 2 is formed so that the grade of the gutter section 2 is made more steep than the rift-like section 1. The gutter section 2 is formed so as to be made deeper than the washing-place base surface 3 of the unit bath, and the downstream section of the gutter section 2 is shaped in depth, in which there is no stepped section between the downstream section and the washing-place base surface 3. Accordingly, the adhesion of mold on a joint, etc., can be prevented effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom having a unit bath structure using a waterproof pan or a tile floor structure by a conventional method, and more particularly to a drainage structure for a bathroom.

[0002]

2. Description of the Related Art For example, in a unit bath shown in FIG. 7, a waterproof pan P is installed on a floor substrate surface portion, and as shown in FIG. 8 or FIG. 100.

[0003] Usually, the washing area 100 includes
For example, as shown in FIG. 10, a stone-grained portion 101 (hereinafter referred to as a stone-grained portion) in which unevenness (for example, embossing or pear-skinning) is provided to prevent slipping, and between the stone-grained portions 101. A small groove for drainage (hereinafter referred to as a groove) 102 provided therebetween.
Are formed.

[0004] Usually, the washing part is provided with a drain port 1.
The structure is such that the stone-grained portion 101 and the groove portion 102 are inclined so as to gradually decrease toward 03 (see FIG. 11).

[0005]

However, in a washing place having such a structure, the groove is usually provided with the same slope in accordance with the slope of the stone-grained portion. Considering the anti-slip property and the like, it is difficult to give a large gradient to the stone-grained portion (approximately, for example, about 1 °). Therefore, as shown in FIG. And the drainage performance by the groove 102 was poor. Such a situation is the same even in a bathroom using a tile of a conventional construction method, and has a similar problem.

Further, this waterproof pan is made of, for example, FRP.
In the case of molding integrally with the above, there is a case where a desired drainage gradient (performance) cannot be ensured due to warpage or the like at the time of molding.

In view of the above circumstances, the present invention can surely enhance drainage performance, and has a structure in which a waterproof pan is integrally formed by FRP or the like. It is an object of the present invention to provide a bathroom drainage structure capable of obtaining the same high drainage performance.

[0008]

That is, the present invention according to claim 1 is a unit structure formed of FRP or the like or a conventional structure formed by attaching a surface plate such as a tile or a stone plate to a concrete floor or the like to form a washing place. In the above-mentioned bathroom, each drain groove provided at the washing place portion inclined toward the drain port is configured to be inclined at an angle larger than the installation inclination angle of the surface processing portion of the washing place main body or the surface plate.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a drainage structure of a unit bath using a waterproof pan according to the present invention (in this embodiment, formed integrally with FRP or the like). The gradient of the groove portion (constituting the drainage groove) 2 is larger than the gradient of the surface processing portion (constituting portion 1) 1, and the drainage efficiency is improved. In addition, the code | symbol 3 in FIG.
Reference numeral 4 denotes a drain port, and reference numeral 5 denotes a main body of the waterproof pan.

As shown in FIG. 2, the groove 2 has a structure in which the upstream portion away from the drain port 4 is shallow and the downstream portion near the drain port 4 is formed deep, and has a slight slope. It is configured such that the gradient is steeper than that of the stone tone part 1. In this embodiment, as shown in FIG. 3, the groove 2 is configured to be deeper with respect to the washing base surface 3, but as shown in FIG. 4 and FIG. The downstream part may be formed at a depth such that there is no step between the washing part base surface 3 and the washing place base surface 3.

Next, another embodiment according to the present invention will be described. In the bathroom drainage structure of the second embodiment shown in FIG. 6, a waterproof pan integrally formed by FRP or the like is not used.
It has a conventional construction, for example, a structure in which a tile (constituting a surface plate) 6 is attached to a floor substrate surface formed by striking concrete by using an appropriate adhesive material such as putty or the like. The portion 7 is formed so as to be inclined more greatly than the inclination of the attachment surface of the tile 6.

In particular, the tiles 6 of this embodiment are not smooth but preferably have a non-slip process such as unglazed or the like. However, the surface of a stone plate obtained by cutting granite, Izu stone or the like into a thin shape is provided with irregularities. Things or natural stones may be used as they are.

In place of the second embodiment, for example, in a configuration in which a tile or the like is adhered with an appropriate adhesive material to a washing scene of a waterproof pan formed of, for example, FRP or the like, a gradient larger than the gradient of the tile is applied. The provided groove may be formed.

[0014]

As described above, according to the present invention, a bathroom having a unit structure formed of FRP or the like or a conventional structure having a washing place formed by attaching a surface plate such as a tile or a stone plate to a concrete floor or the like. In each of the above, the drains provided in the washing area inclined toward the drain are configured to be inclined at an angle larger than the installation inclination angle of the surface processing part of the washing area main body or the surface plate. It can be used for a long period of time because it can improve drainage performance without causing inconvenience, and in particular, without causing a dangerous accident at the time of bathing such as slipping and getting injured when walking. Also, it is possible to effectively prevent mold from forming on joints and the like, and a comfortable bathroom environment can be realized.

In addition, in the case of this bath which is integrally formed by FRP or the like, since the gradient of the groove is formed in advance, a good drainage performance is obtained even if a warp or the like occurs at the time of forming. Can be secured.
