Description

  The present invention relates to a bathroom floor component suitable for use as a floor or waterproof pan of a bathroom unit installed in an apartment, a general house, or the like.

  A bathroom unit using a floor formed of waterproof FRP or the like is often installed in an apartment house such as a condominium or a general house. Floors made of FRP, etc. are slippery and have poor drying performance, so there are rock-like irregularities and anti-slip effects on the surface and joints for drainage, but the surface tension of polka dots Large amounts of water accumulate on joints and rocks, making it difficult to dry. Therefore, as a countermeasure, anti-slip is formed by forming an anti-slip convex part, a channel connected to the drainage port between the convex parts, and further forming an irregularity that destroys the surface tension of the polka dots in the channel. Some have aimed to improve the effect and drying performance (see Patent Document 1).

JP 2002-242410 A

  The above method has an anti-slip effect, and further narrows the flow path connected to the drainage port between the convex portions of the small sections that destroy the surface tension of the polka dots, and further appropriately applies the surface tension of the polka dots in the flow path. Drying performance is achieved by forming irregularities to break and draining water from the flow path. The present invention provides a bathroom floor component having a non-slip effect and a drying performance based on a principle different from this principle.

The present invention relates to the following.

A convex portion having water repellency, a plurality of independent recess and destroy thinly spread polka dot to be left on the surface keep dispersed water the water ball would be arranged and formed at a predetermined pitch around which The bathroom has a diameter or width of the recesses of 1 to 3 mm, a pitch of the recesses of 1 to 3 mm, a depth of the recesses of 0.2 to 0.5 mm, and a portion between the recesses as a flat floor surface. Floor component.
4). 2. The surface obtained by subjecting the surface excluding the portion having water repellency to a hydrophilic treatment . Or 3. The floor component for bathroom as described in 2.

In the bathroom floor component according to the present invention, after use of the bathroom, the remaining polka dots are thinly spread by the recessed portions formed at a plurality of independent predetermined pitches to destroy the polka dots, and the water in each recessed portion is in a small amount. Therefore, it is possible to dry the floor in a short time after using the bathroom.
In particular, the diameter or width of the recesses is 1 to 3 mm, the pitch of the recesses is 1 to 3 mm, the depth of the recesses is in the range of 0.2 to 0.5 mm, the recesses are sufficiently small, and the portions between the recesses are flat. By using the floor surface, the plurality of independent recesses spreads and destroys the polka dots and distributes the water to the individual recess units, so that the water dries in each independent recess in a short time.
In addition, a plurality of independent recesses provide a frictional resistance on the sole, improving the anti-slip effect.
Moreover, since the destruction of a polka dot is accelerated | stimulated by the water-repellent effect by having a flat part or a convex part, the drying time of the floor after bathroom use can be shortened. Moreover, the speed which destroys a polka dot is strengthened by giving a hydrophilic treatment to a floor surface, and drying time can further be shortened.
Furthermore, on the surface having a flat portion or a convex surface portion, the diameter or width of the concave portion formed at a predetermined pitch is 1 to 3 mm, the pitch of the concave portion is 1 to 3 mm, and the depth of the concave portion is 0.2 to 0.5 mm. By making the recesses sufficiently small as a range and making the part between each recess a flat floor surface, independent multiple recesses spread and destroy the polka dots thinly and distribute the water to independent recess units, so it is independent Water can be dried in a short time in each of the recessed portions.

Hereinafter, more specific description will be given with reference to the drawings.

In the bathroom, the floor constituent member 1 and the bathtub 2 are adjacent to each other, and the drain outlet position 3 is arranged in a part of the floor constituent member 1. The floor component 1 is provided with a drainage gradient toward the drain outlet position 3. The floor component 1 may be formed integrally with the bathtub 2, may be formed integrally with a bathtub installation table called a bathtub waterproof pan, or may be formed separately from the bathtub installation table. In this figure, although the drain outlet position 3 is located in the center which the bathtub 2 and the floor structural member 1 adjoin, it may be located in what kind of place. A joint 4 is provided in the floor constituting member 1 in a groove shape, and the floor is partitioned into a relatively large area, but the joint 4 may be omitted. On the surface 5 divided by the joint 4 of the floor, the joint 4 divided into several parts is formed. The surface 5 has the following surface pattern. In FIG. 1, a part of the surface pattern is schematically shown by shading, but it is assumed that it is applied over the entire surface 5. However, the surface pattern is applied only to a part of the floor surface, for example, only in the vicinity of the entrance to the bathroom, only in the vicinity of the drain, only in the part facing the bathtub, or in a continuous part connected to two or more of these. May be. That is, it should just be given to the part which wants to dry a floor quickly.

It is preferable that the convex portion width 19 of the convex portion 8 is 5 to 7 mm, the convex portion pitch is 10 to 15 mm, and the convex height 20 is 0.1 mm or more. If the material of the floor component is a plastic such as FRP, the surface exhibits water repellency. The water contact angle of the water repellent surface is preferably 60 degrees or more. The shape and arrangement of the concave portions 6 and the convex surface portions 8 arranged in an island shape are free. A shape with no corners that does not impair the cleanability is desirable. It is particularly desirable that the convex portion having water repellency has an area and a height at which no water droplets remain on the convex portion due to the water repellent effect.

FIG. 15 is an enlarged partial cross-sectional view showing the behavior of water in the surface pattern of FIG.
As shown in FIG. 15 (a), the polka dots 9 accumulated on the surface 5 are broken by the recesses 6 and spread toward the surrounding recesses 6 in the direction of water flow 10, but are shown in FIG. 15 (b). As shown in FIG. 15 (c), the water repellent effect appears due to the convex shape of the convex portion 8, and the water 13 is moved in the direction 12 so that the water 13 is pushed out. Accumulates. The water 11 accumulated in the recess does not aggregate and re-form polka dots. When the surface has water repellency, the water repellency is further strengthened by the convex surface portion 8 having a convex shape.

  FIG. 16 is a partially enlarged cross-sectional view in the case where, for example, the entire surface of the surface pattern in FIG. The hydrophilic treatment with fine irregularities may be performed only on a part of the surface. As a hydrophilic treatment, a texture 21 that destroys polka dots is provided in the concave portion 6 and the flat portion 7. This wrinkle pattern can be applied to part or all of the surface pattern in other examples. The texture 21 is an arithmetic operation when the horizontal and vertical (XY) direction resolution is set to 0.0364 μm, the height (Z) direction resolution is set to 0.05 μm, and the measurement length is 5 μm. It is preferable that the average roughness Ra is 0.7 μm or more, or the ratio Sm / Ry between the average interval Sm of unevenness and the maximum height Ry is 0.2 or less. The upper limit of the average value of the arithmetic average roughness Ra is appropriately determined, but is preferably 3.2 μm or less. Moreover, although the minimum of ratio Sm / Ry is determined suitably, it is preferable that it is 0.0025 or more. These values may be average values of measurements at five or more locations. As a method for performing hydrophilic treatment, a method for producing a floor constituent member according to the present invention by molding with a mold having a texture pattern corresponding to a molded product, a floor surface of the floor constituent member is directly processed with a paper file or the like. And a method of applying a hydrophilic paint (such as a photocatalyst containing polysilazane or titanium oxide) to the floor surface of the floor constituent member can be employed. The hydrophilic treatment may be formed in either the range where the concave portion 6 is formed or the range where the island-like flat portion 7 or the convex surface portion 8 is formed. In the case of a texture pattern, the entire surface is hydrophilized. That is, once the polka dots are spread, they do not aggregate. The degree of hydrophilicity is preferably less than 60 degrees and more preferably 10 to 40 degrees in terms of water contact angle. When measuring the contact angle of water when the surface has fine irregularities such as a textured pattern, place the measurement object on the horizontal platform of the contact angle measuring instrument, illuminate the light from the side, and expand the projection. Using the boundary with the droplet as a reference, the tangent to the droplet passing through the edge of the droplet and the angle formed by the reference are read. A large object to be measured such as a waterproof pan may be measured by cutting into small pieces.

FIG. 17 is an enlarged cross-sectional view showing the behavior of water when the surface of the surface pattern of FIG. 8 is subjected to hydrophilic treatment.
A hydrophilic treatment is performed on the concave portion 6 and the flat portion 7 formed on the surface 5. As shown in FIG. 17A, the polka dots 9 accumulated on the surface 5 are destroyed by the recesses 6 and spread toward the surrounding recesses 6 in the direction 10 of water flow, but the surface is made hydrophilic. As a result, the destruction of polka dots is further promoted (prompt drainage of water is promoted) and the spreading time is shortened. As shown in FIG. 17B, the water remaining in the flat portion 7 remains thinly extended because the flat portion is made hydrophilic, and quickly dries because the surface area is increased.
