As shown in FIG. 2, the bathroom floor panel 10 according to the first embodiment of the present invention is a floor panel mainly used for a washing place of the bathroom 400. The bathroom floor panel 10 is formed of a resin material such as FRP (Fiber Reinforced Plastic), for example. The bathroom floor panel 10 includes a drain outlet 300 for draining water on the bathroom floor panel 10 and a plurality of island-shaped protrusions spaced from the surface of the bathroom floor panel 10. 110 is provided. The bathroom floor panel 10 further includes a water conduit 120 formed between the convex portions 110 so as to surround the convex portions 110. The water conduit 120 is formed in at least two directions so as to have a plurality of intersections 130, and is continuously provided up to the drain outlet 300.

  A recess 200 is provided on the bottom surface 132 of the intersection 130 of the water conduit 120. Thereby, when water flows into the water conduit 120, the water can be continuously present up to the drain outlet 300 without interruption.

  That is, as illustrated in FIGS. 1A to 1C, the bathroom floor panel 10 according to the present embodiment is provided between the plurality of protrusions 110 provided on the surface and the plurality of protrusions 110. In addition, a water conduit 120 continuous to the drain port 300 is provided. In this example, the convex portion 110 has a rectangular shape in an upper plan view, but is not limited thereto, and can have various shapes such as various polygons and curved contours. Moreover, the arrangement | positioning can also have various arrangement | positionings, such as a brick-stacked arrangement | positioning from which the arrangement | positioning phase shifted | deviated, and a hexagonal close-packed arrangement | positioning other than a lattice form so that it may mention later.

The water conduit 120 has a first gap 121 and a second gap 122. In this example, the first gap 121 extends in a first direction parallel to the AA line direction. In this example, the second gap portion 122 extends in a second direction parallel to the BB line direction. That is, the first gap portion 121 and the second gap portion 122 are substantially orthogonal to each other. However, the present invention is not limited to this, and the first direction (first gap 121) and the second direction (second gap 122) intersect (if they are not parallel). good. A recess 200 is provided on the bottom surface 132 of the intersection 130 where the first gap 121 and the second gap 122 intersect.
A small amount of water can be retained in the recess 200 without being affected by the drainage gradient in the water conduit 120.

  The convex part 110 can be a rectangle of about 5 mm × about 10 mm, for example, in an upper plan view, and the height can be about 0.5 mm, for example. Further, the width of the water conduit 120, that is, the first gap portion 121 and the second gap portion 122 can be set to 2 mm, for example, and the depth can be set to 0.5 mm, for example. However, the present invention is not limited to this.

And the depth h of the recessed part 200 can be 1 mm or less, for example. That is, the height difference between the bottom surface of the recess 200 and the bottom surface 132 adjacent to the recess 200 in the water conduit 120 is desirably 1 mm or less, and more desirably 0.5 mm or less.
In the example shown in FIG. 1, the recess 200 is substantially circular in an upper plan view, and the diameter can be set to, for example, 0.2 to 2 mm. However, as described later, the present invention is not limited to this.

FIG. 3 is a schematic perspective view illustrating the structure of the main part of a mold used for manufacturing the bathroom floor panel according to the first embodiment of the invention.
As shown in FIG. 3, the mold 10 a used for manufacturing the bathroom floor panel 10 according to the present embodiment includes a mold concave portion 110 a corresponding to the convex portion 110 and a mold corresponding to the first gap portion 121. A convex portion 121 a and a mold convex portion 122 a corresponding to the second gap portion 122 are provided. A protrusion 200 a corresponding to the recess 200 is provided in the mold intersection 130 a corresponding to the intersection 130. The bathroom floor panel 10 according to the present embodiment can be obtained by molding the resin using the mold 10a having such a shape.

  In addition, although the water conduit 120 is provided in contact with the convex part 110 between the convex parts 110, a plurality of gaps (first first) are formed between the convex parts 110 by forming the convex part 110 substantially. A gap portion 121 and a second gap portion 122) are provided, and thereby a main portion of the water conduit 120 is configured. In other words, the water conduit 120 can be automatically provided by providing the convex portion 110, and therefore does not need to be provided separately from the convex portion 110. However, the water conduit 120 may be provided by a process different from the process of forming the convex part 110 as long as it is formed between the convex parts 110 so as to surround the convex part 110.

The operation of the bathroom floor panel 10 having the above-described configuration will be described.
FIG. 4 is a schematic perspective view illustrating the drainage state of the bathroom floor panel according to the first embodiment of the invention.
FIG. 4A shows the initial state, FIG. 4B is a diagram following FIG. 4A, and FIG. 4C to FIG. 4F are diagrams following the previous diagram. It is.
As shown in FIG. 4A, when the bathroom is used normally, the surface of the bathroom floor panel 10 gets wet. At this time, if a two-dimensional mesh-like groove (water conduit 120) is provided on the surface of the bathroom floor panel 10, the groove (water conduit 120) is formed by the water 160 on the surface of the bathroom floor panel 10. Part of the water is temporarily trapped in the groove (water conduit 120). That is, water 160 is trapped in the water channel 120 by the intermolecular force of water on the wall surfaces of the first gap part 121 and the second gap part 122 of the water channel 120, and the surface of the bathroom floor panel 10 is Then, a continuous (two-dimensional) water channel is formed up to the drain port 300.

  As shown in FIG. 4B, when the bathroom is used in this state, most of the water on the surface of the bathroom floor panel 10 is caused by a normal drainage gradient 310 provided on the bathroom floor panel 10. The water flows through the entire surface of the water conduit 120 and the floor panel 10 for bathroom and is drained. At this time, a polka dot 150 is formed on the surface of the bathroom floor panel 10, and the polka dot 150 temporarily remains on the surface of the bathroom floor panel 10.

  However, as shown in FIG. 4C, the polka dots 150 are not independent, and the water 160 captured in the water conduit 120 and the polka dots 150 are in contact with each other. Due to the surface tension, the polka dots 150 are gradually drawn into the water conduit 120. Then, the water is drained through the water conduit 120.

As shown in FIG. 4D, after a while, all of the polka dots 150 are guided to the water conduit 120, and the polka dots disappear.
As shown in FIG. 4E, the amount of water 160 in the conduit 120 is temporarily increased by drawing the polka dots 150 into the conduit 120, but the water 160 in the conduit 120 is slowly Since the water is drained without interruption, the amount of water 160 in the water conduit 120 decreases with time.
Then, as shown in FIG. 4 (f), after a while, most of the water 160 in the water conduit 120 is also drained. At this time, if the water 160 remains in the water conduit 120, the amount of the water 160 is small and scattered over a wide area of the surface of the bathroom floor panel 10, so that it is naturally dried. As a result, the surface of the bathroom floor panel 10 can be completely dried in a short time. For example, natural drying is possible in about 8 hours in an environment of an average bathroom environment of a temperature of 15.3 ° C. and a humidity of 66%.

In this way, in a bathroom floor panel that drains by providing a groove (water channel 120) on the surface, the wettability and flow down depending on the shape, dimensions, arrangement, surface wrinkles, etc. of the groove (water channel 120). A large amount of resistance is generated, and the water 160 is continuously captured in a state where the water 160 is connected in the water conduit 120, thereby efficiently draining water.
At this time, in order to stabilize the drainage performance, it is necessary to provide the water conduit 120 at a finer, deeper, or finer pitch, and capture the water 160 in the water conduit 120 without interruption.

  In such a floor, when it is desired to improve the cleanability, the groove that becomes the water conduit 120 may be thicker, shallower, and more sparse. However, in this case, the water catching power of the water conduit 120 is lowered, and the drainage performance is lowered. And, the surface of the bathroom floor panel becomes dirty or scratched, and when the surface condition is different from the initial state, the drainage performance tends to be remarkably lowered. Dirt and scratches on the surface deteriorate the durability related to drainage. Thus, the cleaning property and the drainage property (drying property) are in a trade-off relationship.

In order to improve the cleaning performance, if the groove that becomes the water conduit 120 is thicker, shallower, and sparser, the water capturing power of the water conduit 120 is reduced as a whole. The weak part is the crossing part 130 where the vertical and horizontal grooves intersect, and the water is likely to be interrupted first in this part.
That is, the water 160 existing in the groove (water conduit 120) carved on the surface of the floor panel flows while clinging to the side surface / bottom surface of the groove, and the resultant force of clinging to these portions is inherently the material of the floor panel. If you overcome the water repellency, you can be there without interruption. In the portion of the horizontal groove (first gap portion 121) and the portion of the vertical groove (second gap portion 122), the side wall portions of the groove are present on both sides thereof, but the intersection where the horizontal groove and the vertical groove intersect. At 130, the microscopic side wall of the groove disappears for a moment when viewed microscopically, and the water repellent power of the material itself can be easily achieved by reducing the adhesion of water that was dependent on the side wall part. The phenomenon that the water in 120 is interrupted easily occurs.
When water is interrupted at the intersection 130, the water that starts to break from the intersection 130 also affects the water accumulated in the vertical and horizontal grooves, causing the water in the grooves to be lost extensively. If the water 160 in the water conduit 120 is not continuously connected and there are many parts that are lost, the drainage effect cannot be obtained.

In the bathroom floor panel 10 according to the present embodiment, the bottom surface of the water conduit 120 at the intersection 130 is partially recessed, and a very small amount of water is positively accumulated in the portion, thereby the intersection 130. A state in which water adheres to the water conduit 120 by compensating for the adhesion of water to the water conduit 120, which has been reduced due to the loss of the side wall surface in the water, and prevents the water in the water conduit 120 from being interrupted from the intersection 130. So you can store water. Thereby, improvement of drainage performance and cleanability can be aimed at.
That is, a small amount of water can be retained in the concave portion 200 without being affected by the drainage gradient in the water conduit 120, and thereby, the water is reduced to the water conduit 120 that has been lowered due to the loss of the side wall surface at the intersection 130. It can supplement the adhesion of water.

  In this way, by reinforcing the water capturing ability of the intersection 130 where the water capturing ability is the weakest, it is not necessary to adopt means such as a narrow groove width, a deep groove, and a fine groove arrangement, which cause deterioration in cleaning performance. In addition, it is possible to provide a floor panel for a bathroom that can ensure drainage (dryness) and durability, and achieve both performance, stability and cleanability.

  In this way, in the bathroom floor panel 10, in order to improve the cleanability, the width dimension of the water conduit 120 is increased, the height (depth) dimension of the water conduit 120 is shortened, or the water conduit is Even if the arrangement pitch of 120 is lengthened, the water conduit 120 can temporarily capture the water flowing into the water conduit 120 without interruption, and the residual water that forms the polka dots 150 on the surface of the bathroom floor panel 10 is: By contact with the water 160 temporarily trapped in the water conduit 120, the water is drained from the water conduit 120 to the drain outlet 300 without interruption. On the next day, no water drops remain on the washing area.

That is, in the intersection 130 where the first gap portion 121 and the second gap portion 122 of the water conduit 120 intersect, the surface area per unit area in an upper plan view is larger than that of other portions of the water conduit 120. Small. That is, in the first gap portion 121 and the second gap portion 122 in the vicinity of the intersecting portion 130, for example, the water conduit 120 is surrounded by at least two wall surfaces in contact with the adjacent plurality of convex portions 110. In the intersection 130, for example, as shown in FIG. For this reason, when the recessed part 200 is not provided in the crossing part 130, the surface area per unit area is clearly smaller than parts other than the crossing part 130. At this time, the bathroom floor panel 10 is formed of, for example, a resin such as FRP, its surface is water-repellent, and its surface free energy is smaller than that of water. And in the part where the surface area per unit area is small, water is repelled first, and therefore, the water 160 in the water conduit 120 is easily interrupted at the intersection 130.
At this time, the bathroom floor panel 10 according to the present embodiment is provided with the concave portion 200 on the bottom surface of the intersecting portion 130, so that the surface area per unit area in the top plan view of the intersecting portion 130 can be increased. Thereby, it is possible to prevent the water 160 in the water conduit 120 from being interrupted at the intersection 130.

  Thereby, the bathroom floor panel 10 which concerns on this embodiment can provide the bathroom floor panel which made the drainage property and the cleanability compatible.

  In addition, the dimension of the recessed part 200 provided in the cross | intersection part 130 may be a very small thing about 0.5 mm in depth, and the cleanability is not deteriorated by the dent.

In addition, although the floor panel 10 for bathrooms which concerns on this embodiment showed the example used for the washing-room floor 430 of the bathroom 400 provided with the bathtub 410 and the shower 420, the shower 420 may not be provided, for example. Further, it can also be used as a floor panel of a shower room having only a so-called shower 420 without the bathtub 410. That is, in the present specification, the “bathroom” includes not only a bathroom having a bathtub but also a shower, but includes a shower room.
Furthermore, the bathroom floor panel 10 according to the present embodiment can be used not only as a bathroom washing place but also as a floor panel at the bottom of the bathtub 410. Also in this case, both drainage and cleanability can be achieved.

In the present embodiment, the recess 200 can have various sizes, numbers, and shapes. This will be described below.
FIG. 5 is a schematic partial plan view illustrating the main structure of the bathroom floor panel according to the first embodiment of the invention.
FIG. 5A is a plan view of the bathroom floor panel 10 illustrated in FIG. 1. As described above, the substantially circular concave portion 200 (shown by a shaded portion) is formed at the intersection 130 of the water conduit 120, that is, at the intersection 130 where the first gap 121 and the second gap intersect. Is provided. The diameter of the concave portion 200 is an example smaller than the width of the first gap portion 121 and the second gap portion 122.
FIGS. 5B to 5F are plan views of other bathroom floor panels 11, 12, 13, 14, 15 according to the first embodiment.
As shown in FIG. 5B, in another bathroom floor panel 11 according to the present embodiment, the size of the recess 200 is larger than that of the bathroom floor panel 10 illustrated in FIG. It is large and has substantially the same diameter as the width of the first gap 121 and the second gap 122.
Furthermore, as illustrated in FIG. 5C, another bathroom floor panel 12 according to the present embodiment is an example in which the recessed portion 200 is further larger, and the width of the first gap portion 121 and the second gap portion 122. The diameter of the concave portion 200 is longer, that is, the concave portion 200 is in contact with the convex portion 110. As described above, the size of the recess 200 is arbitrary.

As shown in FIG. 5D, in another bathroom floor panel 13 according to this embodiment, a plurality of recesses 200 are provided for one intersection 130. In this case, the recess 200 is composed of five recesses. Thus, the number of the recessed parts 200 is arbitrary.
Furthermore, as illustrated in FIG. 5E, in another bathroom floor panel 14 according to the present embodiment, a substantially cross-shaped recess 200 is provided along the shape of the intersection 130.
In addition, as shown in FIG. 5F, in another bathroom floor panel 15 according to the present embodiment, the convex portion 110 has a brick-like arrangement in which the arrangement pitch is shifted by about 1/2. ing. In this case, the recess 200 has a substantially T-shape that matches the shape of the intersection 130. Thus, the shape of the recess 200 can have various shapes as well as a circle.

Here, as illustrated in the drawing, the convex portion 110 has an outer shape in a plan view substantially having a straight portion, and a portion where the width of the first gap portion 121 is substantially constant. And having a portion where the width of the second gap portion 122 is substantially constant, a portion excluding the portion where the width of the gap portion is constant can be defined as the intersecting portion 130. That is, the dotted line part in this figure can be defined as the intersection part 130.
When the intersecting portion 130 is defined in this way, in the bathroom floor panels 10 to 15 illustrated in this figure, the recess 200 is provided on the bottom surface inside the intersecting portion 130.
However, the present invention is not limited to this, and the recess 200 can be provided not only on the bottom surface inside the intersection 130 but also beyond the area of the intersection 130.

(Second Embodiment)
FIG. 6 is a schematic view illustrating the main structure of a bathroom floor panel according to the second embodiment of the invention. 6A is a schematic perspective view illustrating the main structure, FIG. 6B is a cross-sectional view taken along line AA of FIG. 6A, and FIG. 6C is FIG. FIG. 6D is a cross-sectional view taken along the line BB of FIG.
The bathroom floor panel 20 according to the second embodiment of the present invention is different from the bathroom floor panel 10 described above in the shape of the recess 200, and the other parts are the same as the bathroom floor panel 10. Therefore, only the recess 200 will be described, and the description of other parts will be omitted.
As illustrated in FIGS. 6A to 6D, the bathroom floor panel 20 according to the present embodiment is provided between the plurality of protrusions 110 provided on the surface and the plurality of protrusions 110. A water conduit 120 is provided, and a recess 200 is provided at an intersection 130 of the water conduit 120. That is, it has a recess 200 provided on the bottom surface of the intersection 130 where the first gap 121 and the second gap of the water conduit 120 provided between the plurality of protrusions 110 intersect, The concave portion 200 indicated by the shaded portion extends to the vicinity of the periphery of the intersecting portion 130 indicated by the dotted line.
That is, the recess 200 is provided inside the intersection 130 and beyond the area of the intersection 130. In this way, the recess 200 may be provided on the bottom surface of the intersection 130, and may be provided beyond the interior of the intersection 130 and beyond the area of the intersection 130 as long as it is not connected to the recess at the adjacent intersection. it can. In this example, the shape of the recess 200 in a plan view has a substantially cross shape.
In this manner, by forming the concave portion 200 as shallow and wide as possible, the surface area per unit water amount of the water staying in the concave portion 200 is widened, so that it becomes easy to dry. Moreover, the water catching power in the water conduit 120 increases more by forming the recessed part 200 in the wide range.

Thus, the recessed part 200 does not need to be provided small only in the intersecting part 130, and the recessed part 200 may be formed in the intersecting part 130.
That is, if the concave portion 200 has a function of compensating for the adhesion force of water to the water conduit 120 that has been lowered due to the loss of the side wall surface of the water conduit 120 at the intersection portion 130, the concave portion 200 is based on the intersection portion 130. Thus, the phenomenon that the water in the water conduit 120 is interrupted can be prevented, and water can be stored in a state where the water is connected in the water conduit 120.
Thereby, the bathroom floor panel 20 which concerns on this embodiment can provide the bathroom floor panel which made the drainage property and the cleaning property compatible.

Hereinafter, modifications of the bathroom floor panel according to the first and second embodiments described above will be described. FIG. 7 is a schematic view illustrating the main structure of another bathroom floor panel according to an embodiment of the invention. 7A is a schematic perspective view illustrating the main structure, FIG. 7B is a cross-sectional view taken along the line AA in FIG. 7A, and FIG. 7C is FIG. 7A. It is a BB sectional view taken on the line.
As shown in FIG. 7, another bathroom floor panel 25 according to the embodiment of the present invention is different from the bathroom floor panel 10 described above in that the surface shape of the convex portion 110 is different. Since it can be the same as that of the floor panel 10 for a bathroom, only the surface shape of the convex portion 110 will be described, and description of other portions will be omitted.
As shown in FIG. 7, the bathroom floor panel 25 has shallow irregularities 111 on the surface of the convex portion 110. The unevenness 111 is provided independently on the upper surface of each protrusion 110, and the height (depth) of the unevenness 111 is low, so unlike the water conduit 120, there is no function to guide water to the drain outlet 300. In addition, it has a function of preventing slipping of the surface of the bathroom floor panel 15, can have a moderately soft texture, and can further enhance design.

Thus, also when the unevenness | corrugation 111 is provided in the surface (upper surface) of the convex part 110, the recessed part 200 of the cross | intersection part 130 supplements the adhesive force of the water to the water conduit 120 reduced by the side wall surface loss of the water conduit 120. It is possible to prevent the phenomenon that the water in the water conduit 120 is interrupted with the intersection 130 as a base point, and water can be stored in a state where the water is connected in the water conduit 120. Also in this case, the recess 200 can have various sizes, numbers, and shapes as illustrated in FIGS. 5 and 6.
Thereby, the bathroom floor panel 25 which concerns on embodiment of this invention can provide the floor panel for bathrooms which made the drainage property and the cleaning property compatible.

FIG. 8 is a schematic view illustrating the main structure of another bathroom floor panel according to the embodiment of the invention. FIGS. 8A and 8B are a schematic perspective view and a plan view, respectively, illustrating the main part structure.
As shown in FIG. 8, another bathroom floor panel 26 according to the embodiment of the present invention is different from the already-described bathroom floor panel 10 in that the shape of the convex portion 110 is different. This is the same as the bathroom floor panel 10.
As shown in FIG. 8B, in the bathroom floor panel 26, the convex portion 110 has a rectangular shape with a long side and a short side having a length of approximately 2: 1 in an upper plan view.
