(Implementation form) [summary] First, using FIG. 1, the outline of the bathroom member 1 of this embodiment is demonstrated. Fig. 1 is a diagram showing a bathroom 90 provided with a bathroom member 1 of this embodiment.

The bathroom component 1, as shown in FIG. 1, is a bathroom floor board used for the floor 91 of the bathroom 90. The bathroom member 1 allows water to flow quickly to the drain 92 provided on the floor 91.

In addition, the bathroom member 1 may also be installed at the bottom 94 of the bathtub 93 arranged in the bathroom 90 shown in FIG. 1. The bathroom component 1 is not limited to use in the bathroom 90, but can also be used in the bottom of a sink or sink in a sink or kitchen, a drain, or the floor of a room or passage with water vapor.

Hereinafter, the specific configuration of the bathroom member 1 will be described in detail using FIGS. 2 and 3.

[constitute] Fig. 2 is a perspective view showing an enlarged part of the bathroom member 1 of the present embodiment. Fig. 3 is a cross-sectional view of the bathroom member 1 along the line III-III in Fig. 2.

As shown in FIGS. 2 and 3, the bathroom member 1 includes a floor member 10, a membrane member 20, and an uneven structure 30. The bathroom member 1 has a seam pattern 11 on the top surface.

The floor member 10 is provided with a seam pattern 11 on the surface. As shown in FIG. 3, the floor member 10 is equipped with the seam pattern 11 and the flat part 12. As shown in FIG.

The seam pattern 11 is a grid-shaped groove provided on the surface of the floor member 10. As shown in FIG. 2, the seam pattern 11 is, for example, a checkered seam pattern (also referred to as a "lattice seam pattern"), and includes a plurality of longitudinal grooves 11a and a plurality of lateral grooves 11b.

The plurality of longitudinal grooves 11a are parallel to each other and arranged side by side at equal intervals. The plurality of lateral grooves 11b are parallel to each other and arranged side by side at equal intervals. The plurality of longitudinal grooves 11a and the plurality of lateral grooves 11b are orthogonal to each other.

The portion surrounded by two adjacent longitudinal grooves 11 a and two adjacent lateral grooves 11 b is a flat portion 12. The flat portion 12 is a flat portion of the surface of the floor member 10. The flat portion 12 is parallel to the xy plane.

The parallel interval of the longitudinal grooves 11a and the parallel interval of the lateral grooves 11b are, for example, the same. In this case, the front shape of the flat portion 12 is a square. The parallel interval of the longitudinal grooves 11a and the parallel interval of the lateral grooves 11b may be different. In this case, the front shape of the flat portion 12 is rectangular. In addition, the longitudinal groove 11a and the lateral groove 11b may cross diagonally. In this case, for example, the front shape of the flat portion 12 is a parallelogram or a rhombus.

The respective widths of the longitudinal grooves 11a and the lateral grooves 11b are on the order of millimeters. For example, the width of each of the longitudinal groove 11a and the lateral groove 11b is 1 mm or more and 4 mm or less, but it is not limited to this width. The respective widths of the longitudinal grooves 11a and the lateral grooves 11b may be shorter than 1 mm or longer than 4 mm. In addition, the width of the longitudinal groove 11a is the length in the short side direction (that is, the y-axis direction) of the longitudinal groove 11a. The width of the lateral groove 11b is the length in the short side direction (that is, the x-axis direction) of the lateral groove 11b.

As shown in FIG. 3, the cross-sectional shape of the longitudinal groove 11a may be an inverted trapezoid, but is not limited to this. The cross-sectional shape of the longitudinal groove 11a may be V-shaped or U-shaped. In addition, the cross-sectional shape of the longitudinal groove 11a may be a rectangle or a square without a push-out portion. The cross-sectional shape of the lateral groove 11b is, for example, the same as the cross-sectional shape of the longitudinal groove 11a, but may be different.

In this embodiment, the entire floor member 10 is inclined downward in the drainage direction. Specifically, as shown in FIG. 2, the longitudinal groove 11a extends in parallel to the drainage direction indicated by the positive direction of the x-axis. The longitudinal groove 11a is inclined at an inclination angle φ with respect to the horizontal plane. The horizontal groove 11b extends in parallel to the horizontal direction indicated by the y-axis direction. The flat portion 12 is inclined at an inclination angle φ with respect to the horizontal plane.

The floor member 10 is based on the premise that a person stands on it. Therefore, in order to reduce the sense of discomfort caused by the inclination of the floor when a person is standing, the inclination angle φ is set to 1.2 degrees or less, for example, 1.1 degrees.

The floor member 10 is formed of, for example, thermoplastic resin or thermosetting resin. Specifically, the floor member 10 is formed of a fiber reinforced plastic (FRP: Fiber Reinforced Plastics) or an SMC (Sheet Molding Compound) material containing glass fiber. Alternatively, the floor member 10 may be formed of artificial marble containing acrylic or polyester as a main component. The floor member 10 is formed, for example, by press forming using SMC material.

The membrane member 20 is provided along the surface of the floor member 10. Specifically, as shown in FIG. 3, the film member 20 is provided to cover each seam pattern 11 and the flat portion 12. The thickness of the membrane member 20 is slightly uniform. As shown in FIG. 3, on the top surface of the film member 20, a groove having a shape that is substantially the same as that of the seam pattern 11 of the floor member 10 is formed.

4 is a perspective view showing the uneven structure 30 of the bathroom member 1 of this embodiment. As shown in FIG. 4, on the top surface of the membrane member 20, an uneven structure 30 is provided.

In addition, the uneven structure 30 is also provided on the seam pattern 11. Specifically, as shown in FIG. 4, the uneven structure 30 is continuously provided in the seam pattern 11 and the flat portion 12 other than the seam pattern 11. More specifically, the uneven structure 30 covers a plurality of flat portions 12 arranged in the y-axis direction, and is provided in the entire flat portion 12 and the longitudinal groove 11a. In addition, the uneven structure 30 is also provided in the lateral groove 11b.

FIG. 5 is a cross-sectional view of the uneven structure 30 and the film member 20 along the VV line in FIG. 4. As shown in FIG. 5, the film member 20 includes a base material 21 and a resin layer 22.

The base material 21 is a member that supports the resin layer 22. The base material 21 is provided on the floor member 10. Specifically, the base material 21 is provided along the seam pattern 11 and the flat portion 12 of the floor member 10.

The substrate 21 is, for example, a resin film, metal foil, or non-woven fabric. As the material of the resin film, polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyvinyl acetate ( PVAc) etc. The size and shape of the base 21 are not particularly limited. The base material 21 has an appropriate size and shape according to the purpose of use and use environment.

The resin layer 22 is provided on the substrate 21. The resin layer 22 is formed using, for example, a photocurable resin material such as ultraviolet curable resin. As the ultraviolet curable resin, silicone resin, acrylic resin, polyurethane resin, etc. can be used. The thickness of the resin layer 22 is, for example, 1 μm to 50 μm, but it is not limited to this thickness.

The resin layer 22 has an uneven structure 30 as shown in FIGS. 4 and 5. The uneven structure 30 is provided on the top surface of the resin layer 22 and is provided on the top surface of the bathroom member 1. That is, when the bathroom member 1 is used for a floor or the like, the uneven structure 30 is exposed on the outermost surface.

In this embodiment, the material constituting the uneven structure 30, that is, the material of the resin layer 22, has a contact angle of 90 degrees or less with respect to water. That is, the resin layer 22 is formed of a hydrophilic material.

As shown in FIGS. 4 and 5, the uneven structure 30 includes a plurality of protrusions 31 and a plurality of recesses 32. The uneven structure 30 is a fine uneven structure having a stripe shape. The stripe shape is a shape in which a plurality of convex portions 31 extending slightly parallel to each other are arranged at predetermined intervals. Between adjacent convex portions 31 are concave portions 32.

In addition, the stripe shape is also called the line and space shape, which alternately arranges the lines and spaces side by side and extends in the same direction. The convex portion 31 corresponds to a line, and the concave portion 32 corresponds to a pitch.

Each of the plurality of convex portions 31 and the plurality of concave portions 32 is elongated along the first direction. The direction in which the convex portion 31 and the concave portion 32 extend, that is, the first direction, crosses the seam pattern 11. Specifically, as shown in FIG. 4, the first direction is orthogonal to the seam pattern 11 and parallel to the y-axis direction.

In this embodiment, the first direction is orthogonal to the longitudinal groove 11a of the seam pattern 11. That is, the first direction is orthogonal to the drainage direction of the bathroom member 1. In addition, the first direction may be orthogonal to the lateral groove 11 b of the seam pattern 11. Alternatively, the first direction may diagonally cross at least one of the longitudinal groove 11a and the lateral groove 11b.

The plurality of convex portions 31 and the plurality of concave portions 32 are arranged alternately in a second direction intersecting the first direction, respectively. The parallel direction of the plurality of convex portions 31 and the plurality of concave portions 32, that is, the second direction, is orthogonal to the first direction. Specifically, as shown in FIGS. 4 and 5, the convex portions 31 and the concave portions 32 are alternately arranged side by side in the x-axis direction one by one.

The shapes of the plurality of convex portions 31 are the same as each other, and the shapes of the plurality of concave portions 32 are the same as each other, but they are not limited to these shapes. The shapes of the convex portion 31 and the concave portion 32 may be different from each other.

As shown in FIG. 5, the cross-sectional shape of each of the convex part 31 and the recessed part 32 is rectangular or square, for example. The width w1 of the convex portion 31 and the width w2 of the concave portion 32 are on the order of micrometers. Specifically, the widths w1 and w2 are 1 μm or more and a length shorter than 1 mm (1000 μm).

In this embodiment, the width w1 of the convex portion 31 is a length equal to or less than the width w2 of the concave portion 32. When viewing the top surface of the bathroom member 1 from the front, the plurality of protrusions 31 occupy an area of less than 50% of the area occupied by the plurality of protrusions 31 and the plurality of recesses 32. To put it simply, the area occupied by the plurality of convex portions 31 is equal to or less than the area occupied by the plurality of concave portions 32. The width w1 of the convex portion 31 is, for example, in the range of 5 μm or more and 50 μm or less, and is 10 μm as an example. The width w2 of the recessed portion 32 is, for example, a range of 5 μm or more and 50 μm or less, and is 10 μm as an example.

The ratio of the depth h of the recess 32 to the width w2, that is, h/w2, is 0.1 or more and 0.6 or less. In addition, the depth h of the concave portion 32 corresponds to the height of the convex portion 31. The depth h is represented by the height from the highest position of the convex portion 31 to the lowest position of the concave portion 32, for example.

In addition, an arc portion (circular arc portion) may be provided at the corner of the front end portion of the convex portion 31. The front end of the convex portion 31 is the front end in the height direction (z-axis direction). In the present embodiment, the cross-sectional shape (xz section) of the convex portion 31 is substantially rectangular, so the top surface of the convex portion 31 (the surface on the positive side in the z-axis direction) corresponds to the front end of the convex portion 31.

The arc part (arc-shaped part) is, for example, a curved surface with a predetermined radius. The predetermined radius is, for example, a length that is 1.4 times or less the height h of the convex portion 31. In addition, it is not limited to the arc-shaped portion, and the corner of the front end portion of the convex portion 31 may be an inclined surface inclined to the top surface of the convex portion 31. Thereby, it becomes difficult for fine dust, dirt, etc. to be caught in the convex part 31, and the antifouling property can be improved.

In addition, the shape of the uneven structure 30 is not limited to the example shown in FIG. 5. Here, the different shapes of the concavo-convex structure 30 will be described using FIGS. 6A and 6B.

Fig. 6A is a cross-sectional view showing a concavo-convex structure 30a which is another example of the concavo-convex structure 30 of this embodiment. As shown in FIG. 6A, the uneven structure 30a includes a plurality of protrusions 31a and a plurality of recesses 32a. The concavo-convex structure 30a differs only in the cross-sectional shape in the short-side direction, and other configurations are the same as the concavo-convex structure 30.

As shown in FIG. 6A, the width of the convex portion 31a is longer in the root portion than in the front end portion. Specifically, the width of the convex portion 31a gradually increases from the tip portion to the root portion. The cross-sectional shape of the convex portion 31a is, for example, a trapezoid. The width wb of the root portion of the convex portion 31a is longer than the width wa of the front end portion.

The width of the concave portion 32a is opposite to the convex portion 31a, and is shorter in the bottom side than the opening side. The cross-sectional shape of the recess 32a is, for example, an inverted trapezoid.

In addition, in the concavo-convex structure 30a shown in FIG. 6A, the width w1 of the convex portion 31a and the width w2 of the concave portion 32a are, for example, the width of the center point in the depth direction of the concave portion 32a (that is, the position of height h/2) Definition, but not limited to this width.

6B is a cross-sectional view showing another example of the uneven structure 30 of the present embodiment, that is, the uneven structure 30b. As shown in FIG. 6B, the uneven structure 30b includes a plurality of protrusions 31b and a plurality of recesses 32b. The uneven structure 30b differs only in the cross-sectional shape in the short-side direction, and the other structure is the same as the uneven structure 30.

As shown in FIG. 6B, the width of the convex portion 31b is longer in the root portion than in the front end portion. Specifically, the width of the convex portion 31b gradually increases from the tip portion to the root portion. The cross-sectional shape of the convex portion 31b is, for example, a semicircular shape.

Furthermore, as shown in FIG. 6B, the convex part 31b has the pushing part 33b in the root part. Specifically, the pushing portion 33b is, for example, a curved surface with a predetermined radius. The predetermined radius is a length equal to or less than 0.1 times the height h of the convex portion 31b. In addition, the pushing portion 33b may not be a curved surface but an inclined surface.

In addition, in the concavo-convex structure 30b shown in FIG. 6B, the width w1 of the convex portion 31b and the width w2 of the concave portion 32b are, for example, the width of the center point in the depth direction of the concave portion 32b (that is, the position of height h/2) Definition, but not limited to this width.

In addition, the shape of the uneven structure is not limited to the above example. For example, the uneven structure may be formed in a zigzag shape or a wavy line shape. For example, the cross-sectional shape of the convex portion may be a triangle, and the cross-sectional shape of the concave portion may be an inverted triangle. That is, the top surface of the convex portion may be sharp and uneven. In addition, the bottom surface of the recess may be pointed and uneven. That is, the concave portion may be a V-shaped groove.

[Production method] Next, the manufacturing method of the bathroom member 1 of this embodiment is demonstrated.

FIG. 7 is a cross-sectional view showing each step of the method of manufacturing the membrane member 20 of the bathroom member 1 of this embodiment. The film member 20 is manufactured using, for example, a transfer technique using a nanoimprint device or a roll-to-roll (Roll-to-Roll) gravure printing device.

First, as shown in (a) of FIG. 7, the base material 21 is prepared, and the resin film 22 a is formed on the prepared base material 21. For example, an ultraviolet curable resin material is applied to the surface of the substrate 21 using a jetting device or the like to form the resin film 22a. At this point in time, the resin film 22a has not hardened yet and can be easily deformed.

Next, as shown in FIG. 7(b), a mold 95 is prepared. The mold 95 is provided with an uneven structure 96 for transferring the uneven structure 30 to the resin film 22a. The uneven structure 96 has a shape that reverses the uneven structure 30.

Next, as shown in (c) of FIG. 7, by pressing the mold 95 against the resin film 22 a, the uneven structure 30 is formed on the resin film 22 a. Specifically, by transferring the uneven structure 96 of the mold 95 to the surface of the resin film 22a, the uneven structure 30 is formed on the surface of the resin film 22a.

At this time, with the mold 95 sufficiently pressed against the resin film 22a, the resin film 22a is cured by irradiating ultraviolet rays from the side of the substrate 21. Thereby, the uneven structure 30 is formed on the resin layer 22.

Finally, as shown in FIG. 7( d ), by removing the mold 95, the film member 20 having the uneven structure 30 is formed.

The membrane member 20 is manufactured as described above. By attaching the manufactured membrane member 20 to the surface of the floor member 10, the bathroom member 1 is manufactured.

[Effects etc.] As described above, the bathroom member 1 of the present embodiment has a seam pattern 11 on the top surface; the bathroom member 1 has a concave-convex structure 30 provided on the top surface, which includes a plurality of convex portions 31 and a plurality of concave portions 32. The plurality of convex portions 31 and the plurality of concave portions 32 are each elongated along the first direction, and are alternately arranged side by side in a second direction intersecting the first direction. The width of each of the convex portion 31 and the concave portion 32 in the second direction is on the order of micrometers. The first direction in which the convex portion 31 and the concave portion 32 extend is a direction crossing the seam pattern 11.

Thereby, the elongated protrusions 31 and the elongated recesses 32 of the uneven structure 30 are formed in stripes, so the droplets adhering to the uneven structure 30 can easily flow along the first direction in which the protrusions 31 and the recesses 32 extend. . The first direction intersects the seam pattern 11, so droplets flowing in the first direction can easily be directly introduced into the seam pattern 11. The droplets introduced into the seam pattern 11 gather with each other to increase the weight, and are drained by the inclination of the seam pattern 11 along the drainage direction.

In this way, the droplets adhering to the surface of the bathroom member 1 are easily introduced into the seam pattern 11, so the amount of droplets remaining on the flat portion 12 (also referred to as residual droplets) can be very small. By reducing the remaining droplets and promoting disappearance due to evaporation or the like, the drying of the bathroom member 1 becomes faster.

As described above, according to this embodiment, a bathroom member 1 with excellent quick-drying properties is provided. By improving the quick-drying property, the increase of mold and slimy parts can be suppressed, and the antifouling property of the bathroom member 1 can also be improved.

In addition, for example, the first direction in which the convex portion 31 and the concave portion 32 extend is a direction orthogonal to the seam pattern 11.

In this way, the droplets are more easily introduced into the seam pattern 11, so the quick-drying of the bathroom member 1 can be improved.

In addition, for example, the ratio of the depth of each of the plurality of recesses 32 to the length in the second direction is 0.1 or more and 0.6 or less.

Thereby, the recessed portion 32 does not become too deep, so that it is possible to prevent dirt from remaining in the recessed portion 32. According to the antifouling test conducted by the inventors of the present application, when the ratio of the depth to the width of the recess 32 is 0.6 or less, sufficient antifouling properties are ensured.

In addition, for example, it is provided with: a floor member 10 provided with a seam pattern 11 on the surface; and a film member 20 having a base 21 provided on the floor member 10 and a resin layer 22 provided on the base 21. The resin layer 22 has an uneven structure 30 on the surface on the opposite side of the base 21.

Thereby, since the uneven structure 30 is provided on the surface of the resin layer 22, the uneven structure 30 with high processing accuracy can be formed by, for example, nanoimprinting. The size of the concavo-convex structure 30 can be easily formed according to the design, so the desired quick-drying can be easily achieved.

In addition, for example, the contact angle of the material constituting the uneven structure 30 with respect to water is 90 degrees or less.

Thereby, since the material constituting the uneven structure 30 is hydrophilic, the droplets flow so as to fill the recesses 32 and flow so as to slide on the droplets filled in the recesses 32. Therefore, the contact portion between the droplet not filled in the concave portion 32 and the uneven structure 30 is only the front end portion of the convex portion 31. The contact area between the droplet and the uneven structure 30 becomes smaller, so the droplet is less likely to receive the frictional force from the convex portion 31, so that it flows smoothly. That is, the water slidability of the droplets is improved, and it becomes easy to quickly introduce into the seam pattern 11. In this way, according to this embodiment, the quick-drying property of the bathroom member 1 can be further improved.

In addition, for example, when the top surface of the bathroom member 1 is viewed from the front, the plurality of convex portions 31 occupy an area of 50% or less of the area occupied by the plurality of convex portions 31 and the plurality of concave portions 32.

Thereby, since the contact area between the convex portion 31 and the liquid droplet can be reduced, the liquid droplet is less likely to receive the frictional force from the convex portion 31, so that it flows smoothly. In this way, according to this embodiment, the quick-drying property of the bathroom member 1 can be further improved.

In addition, for example, the width of each of the plurality of convex portions 31 may be longer in the root portion than in the tip portion.

Thereby, it is easy to introduce the liquid droplets into the concave portion 32, and the liquid droplets become easy to fill the concave portion 32. As described above, by filling the recesses 32 with liquid droplets, the water slidability of the liquid droplets is increased, so that the quick-drying property of the bathroom member 1 can be further improved.

In addition, for example, the width of each of the plurality of convex portions 31 may be gradually increased from the tip portion to the root portion.

Thereby, it becomes easy to introduce the liquid droplets into the concave portion 32 and the liquid droplets easily fill the concave portion 32. Since the droplets are filled into the recesses 32 to increase the water sliding properties of the droplets, the quick-drying properties of the bathroom member 1 can be further improved.

In addition, for example, the plurality of convex portions 31 may each have a push-pull portion at the root portion.

Thereby, since dirt and the like become less likely to be stored in the bottom of the recess 32, the anti-fouling property can be improved.

In addition, for example, the uneven structure 30 is continuously provided at the seam pattern 11 and the flat portion 12 other than the seam pattern 11. Specifically, the plurality of convex portions 31 and the plurality of concave portions 32 are continuous from the flat portion 12 toward the seam pattern 11.

Thereby, since the flat portion 12 and the seam pattern 11 are connected by the continuous convex portion 31, the droplet becomes easier to be introduced into the seam pattern 11.

(other) As mentioned above, although the bathroom member of this invention was demonstrated based on the said embodiment, this invention is not limited to the said embodiment.

For example, the uneven structure 30 may be provided only in the flat portion 12. For example, the film member 20 provided with the uneven structure 30 may be provided only in the flat portion 12. The uneven structure 30 may not be provided in at least one of the longitudinal grooves 11a and the lateral grooves 11b constituting the seam pattern 11.

In addition, for example, in the above-mentioned embodiment, although the example in which the longitudinal groove 11a of the seam pattern 11 is parallel to the drainage direction was demonstrated, it is not limited to this example. The seam pattern 11 may also be provided in a direction diagonally crossing the drainage direction.

In addition, for example, the surface of the floor member 10 may not be inclined to the horizontal plane. That is, the longitudinal grooves 11a and the lateral grooves 11b of the seam pattern 11 and the flat portion 12 may be parallel to the horizontal plane.

In addition, for example, in the above-described embodiment, although a hydrophilic material is used to form the uneven structure 30, a water-repellent material may be used to form the uneven structure 30.

In addition, for example, the concave-convex structure 30 may be directly provided on the top surface of the floor member 10 having the seam pattern 11. That is, the bathroom member 1 may not include the membrane member 20.

In addition, for example, in the above-mentioned embodiment, although an example in which the inclination angle φ of the surface of the bathroom member 1 is 1.2 degrees or less is illustrated, the inclination angle φ may be greater than 1.2 degrees. For example, if the bathroom member 1 is used in a structure that does not assume that a person is standing, such as the bottom of the bathtub 93, even if the inclination angle φ is greater than 1.2 degrees, it does not give people a sense of discomfort when using it. Way to solve. Therefore, by making the inclination angle φ larger than 1.2 degrees, drainage performance can be improved.

In addition, for example, the contact angle of the material constituting the uneven structure with respect to water may be less than 90 degrees, for example, 80 degrees or less, or 60 degrees or less.
