Abstract

A bathroom floor panel that will dry the next day without fail is provided. When water drops onto a floor panel (1), the surface tension is destroyed by uneven regions (8), spreading the water without forming a water drop shown in phantom line. Further, the uneven regions (8) decrease the flow speed of water, allowing the water in a flow passageway (7) to flow uninterruptedly; thus, although the water drain speed is slow, there is no possibility of water remaining like isolated islands. Further, even if water remains in the uneven regions (8) after the water running in the flow passageway (7), the amount in this case is very small, so that it evaporates in a short time.

Description

Technical floor panel for bathroom.

The present invention relates to a resin bathroom floor panel incorporated as a part of a unit bath. Background technology ''

In recent years, unit baths have become the mainstream for bathrooms in houses and the like. This is because there is no need to apply waterproofing work in advance to the bathroom space in the building by using waterproof floor pans made of a material such as FRP with a waterproof floor.

In addition, in accordance with the recent aging of society, waterproof floor bread is mixed with hot and cold water in order to prevent the user from slipping over his / her legs and tipping over when washing in the washing area. It has a non-slip specification with irregularities so that it does not slip easily even if it does. In addition, a rock floor pattern and a stone pattern are used in the washing of the waterproof floor bread to improve the design.

As such a unit bus, for example, the one disclosed in Japanese Patent Application Laid-Open No. Hei 6-93745 is known.

However, the above-mentioned unit bath waterproof floor pan has a good usability because it is less slippery when washing the body in a washing place, etc., but the unevenness has an adverse effect on the drainage performance in the washing scene, and drains like an island. The remaining water remained in the form of an island even on the next day, because of the large amount of water for its surface area, so it was difficult to dry and remained on the next day without natural drying. This is very uncomfortable when the user cleans the bathtub the next day, and if the socks stand in the washroom in the bathroom, the socks will get wet, which is very unpleasant. It was troublesome because the socks had to be taken off every time cleaning was done, and it was hard for the elderly, especially in winter, because the remaining water was cold. The present invention has been made to solve the above-mentioned problem, and provides a bathroom floor panel that does not impair the anti-slip effect of a washing unit of a unit bath and does not leave residual water in the washing unit on the next day. ^) Disclosure of the invention

In order to solve the above-mentioned problems, a bathroom floor panel according to the first invention has a surface on which a non-slip convex portion is formed, and a flow path which is continuous with a drain port or a flow channel is formed between the convex portions. In addition, at least the concave / convex portion for breaking down the surface tension of the polka dot is formed on the flow path at least.

With such a configuration, both an anti-slip effect and an effect of preventing wetting by residual water can be achieved.

Further, in the first invention, the flow rate of the water flowing in the flow path is suppressed by forming the uneven portion that destroys the surface tension of the polka dots in a direction against the flow of the water, so that the water is interrupted on the way to the island. No longer remains in the shape, and the floor surface can be dried in a shorter time.

Further, in the bathroom floor panel according to the second invention, a convex portion for preventing slippage on the surface and destroying the surface tension of the polka dot, and a flow path continuous to the drain port or the sink groove are formed between the convex portions. Further, in order to prevent the water in the flow path from being interrupted, a configuration is adopted in which a means for reducing the flow velocity in the flow path is provided.

With such a configuration, the floor surface can be dried early, together with the anti-slip effect.

In the second invention, as means for reducing the flow velocity in the flow path, it is conceivable that the downstream flow path is bent or the downstream flow path gradient is reduced.

Further, in the second invention, as means for reducing the flow velocity in the flow path, It is also conceivable to provide fine irregularities serving as obstacles in the flow path. BRIEF DESCRIPTION OF THE FIGURES

Embodiments of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a plan view of a bathroom floor panel according to the first invention, Fig. 2 is an enlarged plan view of the floor panel, and Fig. 3 is an enlargement of a bathroom floor panel of another embodiment according to the first invention. Large plan view, Fig. 4 is an enlarged sectional view taken along line A-A in Fig. 2, Fig. 5 is an enlarged sectional view taken along line B-B in Fig. 3, and Figs. 6 (a) to (c) show floor panels. FIG. 4 is a diagram showing the behavior of water of the present invention.

The floor panel 1 is formed by molding a resin material (for example, FRP) and includes a bathtub installation section 2 and a washing section adjacent thereto. The bathtub installation part 2 is formed separately from the floor panel on the washroom side, and may be a split type that is connected, or a bathtub with a washbasin in which the floor panel on the bathtub side itself has a bathtub shape.

A drain recess 4 for drainage is formed on the washing scene of the floor panel 1, and a drain 3 ′ is arranged in the drain recess 4.

The floor panel 1 is provided with a drainage gradient so that the above-mentioned drainage recess 4 becomes the lowest, so that the water on the floor panel 1 flows along the drainage gradient and is collected in the drainage recess 4. Has become. In this embodiment, a drainage drain groove 5 for assisting drainage is provided in combination with the floor drainage gradient, and water on the floor panel 1 is collected and collected in the drainage recess 4.

In the first invention, anti-slip projections 6 are formed on the surface of the floor panel 1, and a flow path 7 that is continuous between the projections 6 is formed. The flow path 7 is set so as to generally face the drain port 3 or the drainage ditch 5. The shape of the anti-slip projection 6 is not limited to the relatively long shape shown in FIGS. 2 and 4, or the circular shape shown in FIGS. 3 and 5, but may be any _shape.c In addition, the amount of polka dots that can remain independently on the upper surface of the anti-slip convex shape without flowing into the flow path that defines the perimeter of the convex shape is determined under an average bathroom environment, e.g., at a temperature of 15. In an environment of 3 ° C and humidity of 66%, by keeping the air temperature below 2 CC, which allows natural drying in about 8 hours, even if polka dots remain on the upper surface of Can be dried without remaining until the next day.

Also, at least on the flow channel 7 on the floor panel 1, an uneven portion 8 that breaks the surface tension of the polka dot is formed so as to overlap. This uneven part 8 Has a linear shape, and its direction is formed in a direction crossing the convex portion 6 and the flow path 7. As a result, the velocity of the water flowing in the flow path 7 is suppressed by the uneven shape portion 8, and the speed is slow. Flow, and water is not interrupted in the flow path 7.

The surface of the floor panel 1 is provided with a grid-like boundary 9 to the extent that it does not impair the functions of the anti-slip ^ convex 6, the flow path 7, and the unevenness 8 that breaks surface tension. Is increasing the character.

As described above, when water falls on the surface of the floor panel 1, the surface tension is destroyed by the uneven portions 8 as shown in FIG. Spread inside. Then, the spread water flows through the continuously formed channel に and enters the drain port 3 directly or through the drain channel 5.

The uneven portion 8 not only breaks the surface tension to increase the surface area on which water evaporates, but also provides resistance to water flowing into the flow channel 7 and trying to flow. As shown in Fig. 6 (b), the water flowing through the channel 7 is not interrupted. In other words, the drainage in the flow passage 7 is drained surely, but slowly and continuously to the drainage port 3 or the sink 5, so that the water does not remain in an island shape.

Further, even if water remains between the concave and convex portions 8 as shown in FIG. 6 (c) after the water flows through the flow path 7, the amount of residual water in this case is extremely small. It evaporates in time and does not pose a problem in practical use.

FIG. 7 is a plan view of a floor panel according to the second invention. The configuration other than the surface shape of the floor panel is the same as that of the first invention. In the floor panel of this embodiment, a convex portion 10 for preventing slip and breaking surface tension is formed on the entire surface of the floor panel 1, and a flow between the convex portions 10 is formed. The passage 11 is formed by means for suppressing the drainage speed in the passage 11. In addition, the amount of polka dots that can remain independently on the upper surface of the anti-slip convex shape without flowing into the flow path that defines the perimeter of the convex shape is measured under an average bathroom environment, for example, at a temperature of 15. In the environment of 3 ° C and humidity of 66%, by keeping the temperature below 2 CC, which can be naturally dried in about 8 hours, even if polka dots remain on the upper surface of Can be dried without remaining until the next day.

The flow velocity suppressing means in the flow path 11 shown in FIG. 7 is an example in which the flow path 11 at the lower part of the water is bent in a direction against the drainage gradient. There are methods such as forming the lower drain gradient more gently than the other parts, and forming fine irregularities in the flow channel 11 so as to cause drainage resistance. As described above, in order to efficiently dry the water on the surface of the floor panel 1, when guiding the water that has fallen on the surface of the floor panel 1 to the drain port 3, the speed of the water flow is controlled, and It is important to avoid islands and remove water that remains isolated in island form.

In general, the faster the drainage rate on the floor is, the better drainage floor feels.However, if the drainage rate is high, the water that is continuously connected and drained Water that is cut off and left behind is generated, so isolated island-like remaining water is likely to be generated, and eventually it becomes a hard-to-dry floor.

For this reason, in the embodiment shown in FIG. 7, the downstream side of the flow path 11 is bent to reduce the drainage on the downstream side, and the drainage in the flow path 11 is in a congested state. The structure ensures that drainage is not interrupted on the way.

The same effect can be obtained by reducing the drainage gradient on the downstream side. Similarly, as a method of controlling the drainage flow velocity in the flow path 11, it is also possible to control the speed of the drainage flowing in the flow path 11 by providing fine unevenness in the flow path 11 and making it an obstacle In this case, the same effect as above can be obtained. You.

FIG. 8 and FIG. 9 are a perspective view and a plan view of an embodiment of the bathroom floor panel according to the second invention in which another means for suppressing flow velocity is applied. In the floor panel of this embodiment, a convex portion 12 for preventing slip and breaking surface tension is formed on the entire surface of the floor panel 1. The T-shaped convex portion 12 is a substantially rectangular shape of about 5 mm X approximately 10 mm, and has a relatively high height of 0.5 mm. The flow path 13 formed between the adjacent convex portions 12 has a depth and width of 0.5 mm and 2 mm, respectively. It is formed continuously with the drain port 3 (not shown) or the drain groove 5 (not shown) In such a narrow and deep channel, the viscous resistance of water is remarkably exhibited as a flow velocity suppressing effect. In addition, the flow velocity in the flow path 13 can be efficiently suppressed in combination with the effect of the surface tension generated in the narrow flow path.

In the embodiment of the present invention, as shown in FIG. 9, by forming the protruding portion 12 small, the surrounding flow channel 1 (3) The amount of water that can remain independently without flowing into the inside is extremely small, about 0.2 CC. Even if it remains, even under the conditions of the bathroom environment described above, it naturally dries more quickly and ensures drying of the floor surface in a shorter time.

As described above, the convex portions 12 having a rectangular basic shape are arranged vertically and horizontally and staggered from each other, and the flow path 13 formed therebetween is finely changed in direction and branched, and the fine mesh is formed. By arranging the flow path 13 in a shape, the flow resistance in the flow path is increased, and various paths can be taken when water flows toward the lower side of the water.

As shown in FIG. 10 (a) and FIG. 10 (b), the flow path in this embodiment The cross-sectional shape of 13 is a substantially V-shaped flow path in consideration of cleanability, etc. In addition, the cross-sectional shapes of flow path 13 are shown in Fig. 11 (a) to Fig. 11 As shown in (c), any shape such as a substantially square shape or a substantially round shape may be used. In addition, the width and the depth of each of the cross-sectional shapes of the flow path 13 are defined by W ′ as shown in FIGS. 10 and 11. In this case, irrespective of the cross-sectional shape of the flow path 13, the cross-sectional shape is changed on the way as shown in FIGS. 10 (b), 11 (b), and 11 (d). When formed in a step shape or the like, the width of the channel shape portion capable of storing substantially the minimum water is defined as the channel width W.

The shape and arrangement of the convex portions 12 are not limited to the substantially rectangular shape described in the present embodiment, but may be any shape such as a substantially circular shape, a substantially square shape, and a geometric pattern. Even in the case of a combination of different shapes, as a result of the floor panel, the size and path of the channel 13 formed between the convex portions, and the effect of the viscous resistance or surface tension of water generated in the channel 13 as a result, (1) When water is poured on the surface, the polka dots formed on the surface are broken, and for a period of time until the polka dots disappear, the water flowing into the flow path (13) can be temporarily caught without interruption Any arrangement, shape, and path can be used as long as it can produce the flow velocity suppression effect that makes the state.

Next, the operation of the present invention configured as described above will be described.

First, in the first invention, the polka dots formed with the use of water on the surface of the floor panel 1 spread and flow into the flow path 7 as shown by the imaginary line in FIG. 6 (a). And This is due to a general physical phenomenon in which polka dots are cut by the difference in height of the irregularities on the floor surface and tend to flow from the high convex part to the low concave part. The concave portion 8 serves to assist this effect.

Water flowing into the flow path 7 flows through the continuously formed flow path 7 and is discharged. The water is drained directly to the water outlet 3 or through the drain channel 5.

In the case of a conventional general floor, the floor panel is made of a hydrophobic material such as plastic, and the material itself tends to repel water.Drainage in the flow passage is too good and the flow velocity is high. The effect of the angle and floor shape caused by too much or unevenness in the flow velocity causes the water to quickly flow in the flow path 7 even if the IT polka dots are pushed into the flow path 7. The water in the remaining area stagnates, and as a result, the water flowing on the floor panel 1 cannot completely form the polka dot φ form. And tended to remain. '

The uneven shape portion 8 of the first invention breaks down the surface tension of the polka dot, and has an effect of guiding water into the flow path 7 and resistance to water flowing into the flow path 7 and going down. This has the effect of suppressing the flow velocity of the water and bringing the water in the flow path 7 into a traffic congestion state in which the water travels slowly. As a result, it is possible to make the water trapped state filled with the water connected in the flow path 7 and to drain the water in the flow path 7 only at a slow speed. Can be held for a long time. Therefore, even if the surface of the floor panel 1 is hydrophobic, as shown in FIG. State can be maintained for a long time.

In this state, new water is flushed on the surface of the floor panel 1 by bathing and the like, and even if the water once forms polka dots on the surface of the floor panel 1 due to surface tension, these polka dots remain on the floor panel 1. Since it is in contact with the temporarily trapped water that is already present in the flow channel 7, the water in the flow channel 7 is attracted to the water and the water is conveyed to the non-slip convex portion 6 and the uneven portion 8 described above. Due to the synergistic effect of the surface tension breaking action, the water in the polka dots gradually flows into the flow path 7, and slowly but without interruption, flows to the drain port 3 or the drain channel 5. It is drained surely. As a result, the polka dots on the floor panel 1 disappear and do not remain on the floor panel 1.

The attraction and water conduction by the water temporarily trapped in the flow channel 7 utilizes the surface tension of water. Due to surface tension, water tends to become spherical to minimize its surface area, and as a result, becomes a polka dot on hydrophobic substances. However, when a plurality of polka dots that are separately and stably present at the respective surface tensions come into contact with each other, it is better to form large polka dots in 1 r than to keep forming polka dots individually. Due to the smaller surface area and more stability, these waters create the force of uniting when they come into contact. This force is due to the surface tension of each water, which makes it possible for a stagnant polka dot with no external force to act upon contact with other polka dots or moisture. The power to move can be obtained by the surface tension of. In the first invention, the water generated by the surface tension of these two water flows by bringing the water temporarily trapped in the flow path 7 into contact with the remaining water that has newly formed a polka dot on the floor panel 1 surface. Attraction into channel 7Uses water as a water-conveying power, reducing the amount of polka dots remaining alone, thereby shortening the drying time on the surface of floor panel 1.It flows into channel 7 and is temporarily caught. Since the water is not completely stagnant and flows slowly at a reduced speed, the water is temporarily captured in the channel 7 on the floor panel 1 with the passage of time even after the polka dots disappear. The total amount of water drained can be steadily reduced, and the floor panel 1 can be dried early. After a while, after the water flows through the flow path 7, even if water remains between the uneven portions 8, as shown in FIG. 6 (c), the amount of residual water in this case is extremely small. Therefore, it evaporates within a short time, and there is no problem in practical use.

In addition, the state of temporary water capture in the flow channel 7 is caused by polka dots generated on the surface of the floor panel 1. It is sufficient that the fluid flow is maintained until the water is almost attracted and introduced into the flow channel 7.It is assumed that the continuous state in the flow channel 7 is partially interrupted at some part of the floor panel 1 before the polka dots disappear. If the channel 7 that actually touches the polka dot and the lower part of the floor panel 1 are connected by the channel 7 that is in the trapped state of one of the paths, the water of the polka dot流れ流れ Ί Ί Ί Ί Ί Ί 効果効果 Ί 効果.

Also, even in the unlikely event that the connected water capture state in the flow path 7 is interrupted immediately after the disappearance of the polka dots and water remains only in the flow path 7, the discharged water is diffused over a wide area on the floor panel 1. Therefore, it is easier to dry naturally than the water remaining in a polka dot state that remains independently, and does not impair the effect of the first invention.

At the same time, the amount of water remaining on the upper surface of the anti-slip convex section on the floor panel defined by the flow channel without contacting the water in the flow channel is determined by the general bathroom ventilation conditions and average It is kept to a level of 2 CC or less, which can be dried in about 8 hours in an environment of high temperature and humidity. With the remaining amount of water in this range, in a general bathroom environment, natural drying is possible for about 8 hours after bathing until the morning of the next day, so it is unfortunate that it does not touch the flow path at all, Even when polka dots that remain independently are generated, the amount of water can be suppressed to an amount that can be dried within a specified time, and the object of the present invention can be sufficiently achieved, so that there is no problem.

Further, in the embodiment of the second invention shown in FIG. 7, a convex portion 10 having both a non-slip effect and a surface tension breaking effect is formed on the entire surface of the floor panel 1. The area between 0 is defined as the channel 1 1. The water that has flowed on the surface of the floor panel 1 is cut off by the convex portion 10 and pushed into the channel 11. In the flow channel 11, the flow channel on the lower side of the water is bent in a direction against the drainage gradient as a flow velocity suppressing means, and the drainage gradient on the lower side is loosened by comparing it with the other parts. As a result, the drainage performance on the downstream side is reduced, and the drainage in the flow channel 11 has a congested congested state. Therefore, the structure is such that the water in the flow channel 11 is not interrupted on the way. Also, as a method of controlling the drain flow velocity in the flow channel 11, there is a method of providing fine irregularities in the flow channel 11 and suppressing the speed of the drain water flowing in the flow channel 11 by forming an obstacle. .

In general, a higher drainage rate on the floor surface makes it easier to feel that the floor is well drained, so the drainage channel has been conventionally disclosed in Japanese Patent Application Laid-Open No. Various attempts have been made to improve the drainage performance of the interior, even if the floor is made of a hydrophobic material such as plastic. However, water that is connected and discharged in a continuous state is likely to be interrupted on the way, and as a result, water that is left behind will be generated, resulting in island-shaped isolated polka dot residual water, and at first glance good drainage Even if it looked like that, it eventually turned out to be a hard-to-dry floor. Therefore, in the second invention, as in the first invention described above, the flow velocity in the flow path 11 is suppressed by an idea from a completely opposite viewpoint to the conventional technology, and the water in a part of the floor is made difficult to flow. It employs a structure that improves drainage and drying properties as a whole.

According to this, by applying means to suppress the flow velocity in the flow channel 11, a part of the water flowing on the floor panel 1 was captured in the flow channel 11 and connected with the water. By forming the continuous flow path 11 for a while, the polka dots on the floor panel 1 are attracted and guided into the flow path 11 and the polka dots can be gradually destroyed. In addition, since it flows slowly and surely through the flow path 11 without interruption, and drains the water on the surface, the water on the floor can be reliably reduced over time. Spreading a wide range of water on the floor panel 1 promotes efficient natural drying and can significantly reduce the floor drying time. two

At the same time, the amount of water remaining on the upper surface of the anti-slip convex section on the floor panel defined by the flow channel without contacting the water in the flow channel is determined by the general bathroom ventilation conditions and average It is kept to 2 CC or less, which can be dried in about 8 hours in a high temperature and humidity environment. With the remaining amount of water in this range, natural drying is possible for about 8 hours from the time of entry to the next morning in a general bathroom environment. However, even if a polka dot that remains independently is generated, the amount of water can be suppressed to an amount that can be dried within a specified time, and the object of the present invention can be sufficiently achieved. No.

Further, in another embodiment of the second invention shown in FIGS. 8 and 9, a flow path 13 formed between substantially rectangular convex portions 12 formed on the entire surface of the floor panel 1 is provided. By making the width and depth narrow and deep, the water in the flow path 13 is not interrupted. This utilizes the effects of water viscosity and surface tension. Since water itself has viscosity, the viscous resistance easily appears as a flow velocity suppressing effect in the flow path 13 formed thin and deep, so that a sufficient flow velocity suppressing effect can be obtained. In addition, the effect of temporarily trapping water in the flow path 13 is enhanced in addition to the effect of surface tension generated in the form of a thin and deep flow path. For example, if the material of the floor panel 1 is a hydrophobic substance that repels water, However, at first glance, it is possible to temporarily capture water in a continuous state without flowing water. .

Also in the case of channels arranged at a fine pitch ゃ mesh-like channel configuration, viscous resistance easily develops when water flows down, and the water is continuously connected in the channel 13 as in the case described above. This can produce the effect of suppressing the flow velocity, which makes it possible to temporarily capture water.

In addition, the amount of water remaining on the upper surface of the anti-slip convex portion on the floor panel 1 divided by the flow path without contacting the water in the flow path is generally measured. It is kept to a level of 2 CC or less, which can be dried in about 8 hours in an environment with a comfortable bathroom ventilation condition and average temperature and humidity. Even if the remaining water amount is within this range, natural drying is possible for about 8 hours after bathing until the morning of the next day under a general bathroom environment. It does not touch the road at all and remains independently ~ Even if a polka dot occurs. The amount of water can be suppressed to an amount that can be dried within a specified time, and the object of the present invention is sufficiently achieved. It does not matter at all.

In the embodiment shown in FIG. 9, the non-slip convex portion 12 is formed to be small. The amount is further reduced to 0.2 C C to realize reliable drying in a shorter time.

In addition, the state where the amount of water of the polka dots remaining on the upper surface of the protruding portion 12 on the floor panel 1 without contacting the water in the flow path 13 is set to 2 CC or less is a substantial state. Even if there is a portion of the convex portion 12 where the amount of deviation from the above conditions can remain, the floor drying effect is substantially the same as long as the obtained floor drying effect does not change the gist of the second invention. Shall be

As shown in FIG. 9, in this embodiment, the convex portion 12 has a size of about 5 × about 1 O mm, and is vertically and horizontally staggered, and the flow path 13 formed therebetween is finely divided. By changing the direction and branching and arranging the flow path 13 in a fine mesh shape, the flow resistance in the flow path is increased, and various paths can be taken when the water flows down the water. Has been.

This produces an effect that the water of the polka dot is reliably drained along another path even if the state of catching water connected in the flow path 13 is partially interrupted.

In addition, by making the width of the convex portion 12 about 5 mm and forming it with a size close to the average droplet diameter of the water droplet, the effect of polka dot destruction can be enhanced, and the water on the floor panel 1 has a high probability Can contact the water in the flow path 13 Because it is unlikely to exist as an independent polka dot on the convex portion 12, the amount of water that may unfortunately remain on the convex portion 12 is limited to a range that can be dried by natural drying. be able to. In the case of the present embodiment, only the water amount of about 0.2 CC or less is allowed to independently exist on the convex portion 12 by the above-described device and the like. The soil and the floor are dried more reliably.

Utilizing these flow velocity suppression effects and surface tension effects, the water that was temporarily captured while being connected in the flow path 13 produced the same effects as those of the first and second inventions described above. As shown in (1), it becomes possible to attract and guide the polka dots into the flow path 13 and drain them without leaving them. As a result, the floor can be dried at an early stage with the same effect as the first and second inventions. Industrial applicability

As described above, according to the present invention, the surface of the bathroom floor panel is formed with an uneven portion that does not form a polka dot by destroying the surface tension of the polka dot, so that the surface area of the water remaining on the floor surface is reduced. It spreads and dries in a short time, leaving the floor dry the next day without compromising the anti-slip effect.

In addition, by setting the direction of the uneven portion that destroys the surface tension of the polka dots to the direction that resists the flow of water, the flow rate of the drainage to the drainage outlet or the sink is suppressed, and the drainage is not interrupted. As a result, island-like residual water can be eliminated, and the floor can be surely dried within a predetermined time.

In addition, convex portions for preventing slippage and breaking the surface tension of the polka dots are formed on the surface of the bathroom floor panel, and a continuous flow path is formed between these convex portions toward the drain port or the sink groove. Measures have been taken to reduce the flow velocity in the flow channel in order to prevent the water in the flow channel from being interrupted, so that the water on the floor surface can be drained without interruption and the drying performance of the floor surface can be improved. it can. Further, in the bathroom floor panel of the present invention, by controlling the flow rate of the water in the flow path, a part of the water flowing on the floor surface is temporarily captured in a state of being connected to the flow path, and is partitioned by the flow path. Since the amount of water that can remain independently without touching the temporarily caught water in the flow path is set to 2 CC or less on the upper surface of the anti-slip projection, the Since the amount of water that can be lost can be limited to the amount that can be naturally dried within the specified time in a general bathroom environment, the drying performance of the floor can be guaranteed.
