Description

  The present invention relates to the structure of the floor of a bathroom washroom or the bottom of a bathtub.

  In recent years, as a floor pan made of resin such as FRP used in bathroom washrooms, it is provided so as to be dotted with convex portions over the entire surface in order to prevent slipping and to give a pattern to the bottom surface of the floor pan body. The lower part of the floor pan body other than the convex part is the drainage ditch, and this drainage ditch is continued to the drainage part such as the drainage outlet of the floorpan body so that the surface of the drainage ditch is made hydrophilic. For this reason, a structure having fine irregularities has been proposed (see, for example, Patent Document 1).

When draining hot water from the floor pan, it is drained by a water gradient from the entire surface of the floor pan to the drainage part such as the drain outlet, but when the amount of water to be drained decreases, it is mainly drained along the drainage ditch. Become so. At this time, since water is made hydrophilic by providing fine irregularities in the drainage ditch, water cannot be generated due to surface tension, and water is guided by the water while it is connected to the drainage part such as a drainage port. Drained with the action of the gradient. Eventually, the water spreads thinly over the entire drainage ditch and is naturally dried.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In the bathroom 8, as shown in FIG. 2, a resin wash floor pan A such as FRP and a resin bathtub B such as FRP are juxtaposed. A drainage portion such as a drainage port 2 is provided at an appropriate position on the bottom surface of the floor pan body 1 of the floor pan A for washing place, and a water gradient is provided on the bottom surface of the floor pan body 1 so as to become lower toward the drainage portion. It is. In FIG. 2, a water gradient is provided so as to decrease in the direction of arrow a. A drainage portion such as a drainage port 7 is provided on the bottom surface of the bathtub body 6 of the bathtub A, and a water gradient is provided on the bottom surface of the bathtub body 6 so as to become lower toward the drainage portion. In FIG. 2, a water gradient is provided so as to decrease in the direction of the arrow b.

  In the present invention, the fine protrusions 3 having a height of about several tens of μm are provided so as to protrude over the entire bottom surface of the floor pan body 1 and the bottom surface of the bathtub body 6. The fine protrusions 3 are cone-shaped protrusions such as a conical shape, and when a large number of fine protrusions 3 are provided, the roots of the fine protrusions 3 are provided so as to be the same surface (a plane along the water gradient). . The height of the fine protrusions 3 is about several tens of μm, and good hydrophilicity is exhibited when the height is 20 to 30 μm or more. In addition, water repellency will come out if it is 20 micrometers or less. Further, in the present invention, when the fine protrusions 3 are provided so that their roots are flush with each other, the height of all the fine protrusions 3 is not the same, but the height and height of the fine protrusions 3 are the same. The thing of low is provided.

  In the example shown in FIG. 1, when the fine protrusions 3 are provided over the entire bottom surface of the floor pan body 1 and the bottom surface of the bathtub body 6, the one having a high height and the one having a low height are randomly distributed over the entire surface. It is provided so as to be scattered. In the case of this example, it is composed of three types of fine protrusions 3, that is, a fine protrusion 3 a having a high height, a fine protrusion 3 b having a low height, and a fine protrusion 3 c having an intermediate height. The height of the fine protrusion 3b is about 60 μm, the height of the fine protrusion 3b having a low height is about 30 μm, and the height of the fine protrusion 3c which is about the middle of the height is about 40 μm.

In the case of this example, the high fine protrusion group 4 has an island shape as shown in FIG. 3B, and the island-like high fine protrusion group 4 is formed on the bottom surface of the floor pan body 1 and the bottom surface of the bathtub body 6. The portions other than the portion where the island-like high fine protrusion groups 4 exist are provided as the low fine protrusion groups 5 over the entire surface. The height of the fine protrusion 3a having a high height that becomes the high fine protrusion group 4 is about 60 μm, for example, and the height of the fine protrusion 3b having a low height that becomes the low fine protrusion group 5 is about 40 μm, for example.

  In the case of this example, since the fine protrusions 3 are provided on the bottom surface of the floor pan main body 1 and the bottom surface of the bathtub main body 6 so that the root is the same surface, the entire surface is hydrophilic. The entire surface becomes a drainage surface and drainage is performed smoothly. At this time, since the island-like high fine protrusion groups 4 are scattered over the entire surface and the other portions are the low fine protrusion groups 5, of course, there is an anti-slip effect. When the fine protrusion groups 4 are scattered, the pattern is distinguished from the low fine protrusion groups 5 and the appearance is improved.

  The example shown in FIG. 4 (a) also has a high fine protrusion group 4 composed of fine protrusions 3a having a high height and a low fine protrusion group 5 comprising fine protrusions 3b having a low height. The low fine projection group 5 is formed in an island shape so as to be scattered over the entire bottom surface of the floor pan body 1 and the bottom surface of the bathtub body 6, and the portions other than the low fine projection group 5 are the high fine projection group. 4

  In the case of this example, since the fine protrusions 3 are provided on the bottom surface of the floor pan main body 1 and the bottom surface of the bathtub main body 6 so that the root is the same surface, the entire surface is hydrophilic. The entire surface becomes a drainage surface and drainage is performed smoothly. At this time, the island-like low fine protrusion groups 5 are scattered over the entire surface, and the portions other than this portion are the high fine protrusion groups 4. When the fine protrusion groups 5 are scattered, the pattern is distinguished from the high fine protrusion groups 4 and the appearance is improved.

  Further, as described above, the fine protrusions 3a having the high height and the fine protrusions 3b having the low height are provided as the fine protrusions 3. However, the outer shape of the fine protrusion 3b having the low height is the upper part of the fine protrusion 3a having the high height. It has the same shape as the outer shape. That is, as shown in FIG. 5, when the fine protrusion 3a having a high height is cut along the cutting line c, the outer shape of the portion above the cutting line c and the outer shape of the fine protrusion 3b having a low height are the same shape. It has become. If it becomes like this, the process for the part for forming the said fine protrusion 3 in the metal mold | die which shape | molds the floor pan main body 1 and the bathtub main body 6 with resin, such as FRP, will become easy.
