It is about 10 mm and the depth is about 0.3 to 1.0 mm.
In addition, the surface of the smallest section (the part corresponding to one tile) surrounded by the groove was processed to have a rock-faced texture or imitation, imitating natural stone or a sample board, in order to give a natural feeling. .

様付き防水パンを提供することを目的とする。However, in such a waterproof pan, the designability of the surface is too important and the drainage property (quick drying property), slip resistance, stain resistance, etc. are not always sufficient. It cannot be said that the performance is satisfactory. In addition, as the material of the waterproof pan, since plastics such as FRP having relatively high water repellency are often used, the water on the waterproof pan after bathing is large (or thick) on the waterproof pan.
Water droplets are likely to be generated, and it is particularly difficult to evaporate and dry. The present invention, the hot water on the waterproof pan after bathing is smoothly drained,
Its surface is intended to provide a waterproof pan with an uneven pattern that reaches a "dry state" in a short time.

パン１である。As a result of various studies to achieve the above object, the present inventors have found that the size of each of a large number of small compartments surrounded by grooves on the waterproof pan surface is the most important. Furthermore, they have found that the groove width, groove depth, and groove direction of a groove surrounding a large number of small sections are also important factors, and have completed the present invention. That is, the waterproof pan of the present invention has a surface texture consisting of a narrow groove 3a and a small section (minimum section) 3b surrounded by the groove, and is a substantially rectangular rectangular pan in plan view having a drainage gradient. The area of the small section 3b is 0.1 cm 2 or more and 5.0 cm 2 or less, and the narrow groove 3a has a width of 0.3 mm or more and 3.0 mm or less.
Hereinafter, the waterproof pan 1 has a depth of 0.3 mm or more and 1.6 mm or less, and the groove 3a is formed so that the direction thereof is not orthogonal to the drainage gradient and has a downward gradient.

溝３ａで囲まれる小区画の形状は略菱形状が好ましい。Here, the groove 3a is preferably formed so as to be oblique to the long side or the short side of the waterproof pan (washing place). The reason why the direction of the narrow groove 3a is not provided on the vertical / horizontal side in a grid pattern but is oblique to the long side or the short side of the waterproof pan (washing place) is that the direction of the drainage gradient (maximum gradient) is , Orthogonal direction (ie, the direction that impedes flow)
This is because there is no groove. By doing so, it is possible to give a downward slope to any part of the groove, so that the smooth flow of hot water from the narrow groove to the drain port is not hindered. However, a groove orthogonal to the direction of the drainage gradient may be provided to the extent that the drying effect of the waterproof pan in the present invention is not significantly impaired. Further, the shape of the small section surrounded by the narrow groove 3a is preferably substantially rhombic.

であってもよい。The above-mentioned drainage gradient (on the surface of the waterproof pan) is an inclination for draining the drainage remaining on the waterproof pan toward the drain port by the action of gravity. Usually, a downward slope toward the drainage port 2 is provided. In a bathroom where there is a drain ditch around the washing place or a grating, a downward slope to the drain ditch or drain may be used. In addition, the groove formed on the surface of the waterproof pan has a downward slope in any part of the groove, and has a downward slope (in a bathroom with a drain groove around the washing area, the drain groove and a bathroom with a drain groove with a grating). Then it must be connected to the drain. Further, even if the groove formed on the surface of the waterproof pan is a flow path that is connected to one as a whole, a plurality of independent flow paths as a whole (in an independent flow path, the grooves are connected to one Exist)

発する。Most of the hot water on the waterproof pan 1 first flows into the drain port 2 according to the drain gradient. The hot water remaining on the waterproof pan 1 flows into the groove 3a from the small section 3b, and descends into the drainage port 2 through the groove 3a having a downward slope so as to descend the river. At this time, on the waterproof pan 1,
There is still a wide range of hot and cold water, but most of this hot and cold water is 5
Within a short time of about 30 minutes to 30 minutes, it is crushed into small pieces by the surface texture (so that the water droplets of the residual hot water are destroyed), is drawn into the groove 3 a, and falls into the drainage port 2. This 5
Hot water that has not fallen to the drainage port 2 within a short time of about 30 minutes to 30 minutes becomes relatively small (thin) water droplets of about the small section 3b or less, and remains on the small section 3b. The remaining water is then evaporated in evaporation mode under a suitable atmosphere.

By making it below (namely, making it small), even if the water in which the groove is not caught remains on the small section, the generated water droplet becomes a small water droplet having a size smaller than the area of the small section. Therefore, the subsequent evaporation / drying time can be shortened.

濡れない感じの「乾燥状態」となる。In addition, in the rectangular waterproof pan of the present invention, the direction of the groove is not provided vertically or horizontally in the shape of a grid, but obliquely intersects the long side or the short side of the waterproof pan (washing place). By doing so, there is no groove in the direction orthogonal to the direction of the drainage gradient (maximum gradient) (that is, the direction that obstructs the flow), and hot water flows smoothly from the groove to the drain port. I am making it flow. In addition, the drain of the washing place (waterproof pan) is often provided in front of the bathroom counter (center) provided on the short side around the washing place or in the center of the long side of the washing place adjacent to the bathtub side. If the direction of the groove intersects with the long side or the short side of the washroom, or if the shape of the subdivision is roughly rhombic, the drainage port is located on the short side around the washroom as described above. Whether it is in front of the bathroom counter on the side (central part) or in the central part on the long side of the washing area adjacent to the bathtub side, in either case it is orthogonal to the direction of the drainage gradient (maximum gradient) in the groove Since there is no groove in the direction of drainage, it is easy for the drainage to flow smoothly from the groove to the drain port. Thus, the surface of the waterproof pan will be in a "dry state" in which the socks will remain socks and will not get wet even after entering the washing room overnight.

It has a surface texture consisting of subdivisions 3b, and
It is a waterproof pan with a drainage gradient that is substantially rectangular in a plan view, the area of the small section 3b is 0.1 cm 2 or more and 5.0 cm 2 or less, and the narrow groove 3a has a width of 0.3 mm or more and 3.0 m or less.

The direction of the groove 3a is such that there is no direction orthogonal to the direction of the drainage gradient, and moreover, it has a downward gradient. Here, the direction of the groove 3a is, for example, a waterproof pan (washing place).
Is formed so as to intersect with the long side or the short side.

なく、ウェーブがかかった直線状でもよい。Here, the thin groove 3a has a groove width of 0.3 mm or more and 3.0 mm or less and a groove depth of 0.3 mm, because hot water easily enters the groove and the water channel is not easily interrupted. It should be 1.6 mm or less. Groove width is 0.3m
If it is less than m, it is difficult for hot water to enter the groove, and if it exceeds 3 mm, the water channel tends to be interrupted. If the groove depth is less than 0.3 mm, it is difficult to exert the effect of the capillary phenomenon that catches hot and cold water.
If it exceeds mm, it becomes difficult to remove the dirt accumulated in the groove. The vertical cross-sectional shape of the groove may be substantially U-shaped or substantially V-shaped. Further, the shape of the groove in plan view is not limited to a linear shape, and may be a wavy linear shape.

The small sections 3b may have the same size or different sizes. When they are different, the area of the small section 3b is a value defined by an average value. If the area of the small section 3b is less than 0.1 cm 2 , the design is poor and the molding process becomes difficult. If it exceeds 5.0 cm 2 , the size of water droplets that could not enter the groove spreads, and it takes time to dry.

The surface roughness (size of the unevenness) of the whole is preferably 0.3 mm or more and 1.6 mm or less in Rmax (corresponding to the groove depth). If Rmax is less than 0.3 mm, it easily slips when soapy water adheres, and 1.6 mm
If it exceeds the range, hot water tends to be blocked, and dirt tends to adhere easily (difficult to clean). By setting it within the above range, a surface having a large slip resistance value (slip resistant) can be obtained. The slipperiness is related to the groove depth as well as the groove depth.

FIG. 4 is a diagram for explaining the surface roughness of the waterproof pan.
As shown in FIG. 1, the waterproof pan 1 is provided with a drainage port 2 at the end of the washing place (near the place where the bathroom counter is arranged), and on its surface a number of narrow grooves 3a are formed on the long side of the washing place. And running in non-parallel / non-right angles to the short sides, that is, in the vertical and horizontal directions in an oblique direction, and the groove 3a and a large number of small sections (minimum sections) 3b form a surface uneven pattern. Further, joints of about 400 mm square parallel / right to the long side and the short side of the washing area are provided to give a design accent to the entire surface. However, the joint of about 400 mm square may or may not be provided. In addition, in FIG. 1, a surface texture consisting of a groove and small sections surrounded by the groove is formed on almost the entire surface of the washing pan waterproof pan, but such a surface texture is formed on almost the entire surface of the waterproof pan surface. Without
It may be formed partially (for example, avoiding the wall-side end of the waterproof pan, which is less likely to be ridden by a person). Although not shown, a lid is placed on the drainage port 2, and the surface side of the lid has an uneven pattern similar to the surface of the waterproof pan (surface texture).
