Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin bathroom floor panel incorporated as part of a unit bath.

[0002]

2. Description of the Related Art In recent years, unit baths have become the mainstream of bathrooms in houses and the like. This is because it is not necessary to carry out waterproofing work in advance in the bathroom space of the building by using the waterproof floor pan whose floor is made of a material such as FRP having waterproofness.

Further, in accordance with the arrival of the aging society in recent years, in order to prevent the user from slipping over and dropping the waterproof floor pan as much as possible when washing the floor in the washroom, the waterproof floor pan should be hot water. It has a non-slip design with irregularities so that it will not slip even when mixed. In addition, a rock surface pattern or a stone pattern is used to wash the waterproof floor pan to improve the design.

As such a unit bus, for example,
The one disclosed in JP-A-6-93745 is known.

[0005]

However, the above-mentioned waterproof floor pan of the unit bath has a good feeling of use because it is hard to slip when washing in the washing place, but the unevenness has a drainage property in the washing scene. It has an adverse effect and leaves wastewater in an island shape, and even on the next day, the remaining water on the island has a large amount of water relative to the surface area, so it is difficult to dry and does not dry naturally on the next day. Was left in. The next day, when the user cleans the bathtub, it will cause the socks to get wet if he or she stands in the washing area in the bathroom while wearing socks. It is very uncomfortable, and the socks must be taken off after every cleaning. It is troublesome for the elderly, especially because the residual water is cold in winter.

The present invention has been made to solve the above problems, and a bathroom floor panel in which residual water does not remain in the washing area on the next day without impairing the anti-slip effect of the washing area of the unit bath To provide.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. Figure 1 is a plan view of a first embodiment of the bathroom floor panels according to the present invention, FIG. 2 is an enlarged plan view of the floor panel, the embodiment of Figure 3 the floor panel engaging Ru bath chamber to the present invention
2 is an enlarged plan view of FIG. 4, FIG. 4 is an enlarged cross-sectional view of line AA of FIG. 2, FIG. 5 is an enlarged cross-sectional view of line BB of FIG. 3, and FIGS. 6A to 6C are water on the floor panel. It is a figure which shows a behavior.

The floor panel 1 is formed by molding a resin material (for example, FRP), and is composed of a bathtub installation portion 2 and a washroom portion adjacent thereto. The bathtub installation portion 2 is formed separately from the floor panel on the side of the washroom, and may be a divided type to be connected or a bathtub with a washroom in which the floor panel on the side of the bathtub itself has a bathtub shape.

A drain port recess 4 for drainage is formed on the floor panel 1 washing scene, and the drain port 3 is placed in the drain port recess 4.
Are arranged.

The floor panel 1 is provided with a drainage gradient so that the drainage recess 4 is the lowest, and the water on the floor panel 1 flows along the drainage gradient and is collected in the drainage recess 4. It is like this. In this embodiment, a structure is provided in which a drainage drainage groove 5 for assisting drainage is provided together with the floor surface drainage gradient, water on the floor panel 1 is collected, and the water is collected in the drainage port recess 4.

In Embodiments 1 and 2 , the floor panel 1 is provided with the anti-slip projections 6 and the continuous flow path 7 between the projections 6 on the surface thereof. The flow path 7 is set so as to generally face the drainage port 3 or the drainage drainage groove 5. The shape of the non-slip convex portion 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, and may be any shape.

In addition, the amount of polka dots that can independently remain on the upper surface of the convex non-slip surface without flowing into the flow path dividing the convex periphery is measured under an average bathroom environment, for example, at the temperature. Even if a polka dot remains on the upper surface of the convex shape, it can be dried up to the next day by keeping it to 2CC or less that can be naturally dried in an environment of 15.3 ° C and humidity of 66% for about 8 hours. It can be dried without being left behind.

Further, at least the flow path 7 on the floor panel 1 is formed with a concavo-convex shaped portion 8 that breaks the surface tension of the polka dots. The uneven portion 8 has a linear shape, and the direction thereof is formed so as to cross the convex portion 6 and the flow path 7. As a result, the speed of water flowing in the flow path 7 is disturbed by the uneven portion 8. The flow is suppressed, the flow becomes slow, and the water does not break in the flow path 7.

Further, on the surface of the floor panel 1, a grid-like boundary portion 9 is provided within a range that does not impair the functions of the convex portion 6 for slip prevention, the flow path 7 and the concave and convex portion 8 that destroys the surface tension. To improve the design.

In the above, when water falls on the surface of the floor panel 1, as shown in FIG. 6 (a), the surface tension is broken by the uneven portion 8, and the flow path 7 is formed without forming the polka dots shown by the imaginary line. Spread inside. Then, the spread water flows through the continuously formed flow path 7 and enters the drainage port 3 directly into the drainage port 3 or through the drainage drain groove 5.

The uneven portion 8 not only breaks the surface tension and increases the surface area of water that evaporates, but also resists the water that flows into the flow path 7 and tends to flow.
The flow velocity in the flow path is suppressed, and as shown in FIG. 6B, the water flowing through the flow path 7 is not interrupted. That is, the drainage in the flow path 7 is slowly but surely drained in a state where it is continuously connected to the drainage port 3 or the drain groove 5, and as a result, the water does not remain in an island shape.

Further, after the water flows through the flow path 7, the flow shown in FIG.
As shown in (c), even when water remains between the uneven portions 8, since the residual water amount in this case is extremely small, it evaporates in a short time, which is not a problem in practical use.

[0021] Figure 7 is a real bathroom floor panel according to the present invention
It is a top view of Example 3 . The structure other than the surface shape of the floor panel is the same as that of the above-described embodiment . In the floor panel of Example 3 , the entire surface of the floor panel 1 also serves as a slip stopper,
It is formed by forming convex-shaped portions 10 for breaking the surface tension, forming channels 11 between the convex-shaped portions 10, and providing a means for suppressing the drainage speed in the channel 11.

In addition, the amount of polka dots that can remain independently on the upper surface of the convex non-slip shape without flowing into the flow path that divides the convex shape is average temperature in a bathroom environment, for example. Even if a polka dot remains on the upper surface of the convex shape, it can be dried up to the next day by keeping it to 2CC or less that can be naturally dried in an environment of 15.3 ° C and humidity of 66% for about 8 hours. It can be dried without being left behind.

The flow velocity suppressing means in the flow channel 11 shown in FIG. 7 is an example in which the flow channel 11 in the lower part of the water is formed in a state of being bent in a direction against the drainage gradient. There are means such as forming the drainage gradient on the side gentler than that of the other portions, or forming fine irregularities in the flow path 11 that cause drainage resistance.

As described above, in order to efficiently dry the water on the surface of the floor panel 1, when the water dropped on the surface of the floor panel 1 is guided to the drainage port 3, the speed of the water flow is controlled so that the drainage water is discharged. It is important to prevent water from being isolated in islands so that there is no break in the middle. Generally, the faster the drainage speed on the floor surface is, the more easily it feels like “a floor with good drainage”, but if the drainage speed is fast, the water that is continuously connected and drained will be interrupted in the middle. Since the water that is left behind is generated, island-like isolated residual water is likely to be generated, and finally the floor becomes hard to dry.

Therefore, in the third embodiment shown in FIG. 7, the downstream side of the flow path 11 is bent to reduce the drainage performance on the downstream side, and the drainage in the flow path 11 is blocked by the congestion. The structure is such that the generation of wastewater does not interrupt the process. The same effect can be obtained by making the drainage gradient on the downstream side gentle.

[0026] Also, as a method to slow down the drainage flow rate in the flow channel 11 is provided with fine irregularities in the flow path 11, also slowing the speed of the waste water flowing through the flow passage 11 by an obstacle In this case, the same effect as above can be obtained.

8 and 9 are a perspective view and a plan view of a fourth embodiment for slowing down another flow velocity suppressing means of the bathroom floor panel according to the present invention. In the floor panel of this example,
A convex portion 12 is formed on the entire surface of the floor panel 1 for the purpose of preventing slippage and breaking surface tension. The convex portion 12 has a substantially rectangular shape of about 5 mm × about 10 mm and has a relatively high height of 0.5 mm. In addition, by making the interval between the respective convex-shaped portions 12 extremely close to 2 mm, the flow path 13 formed between the adjacent convex-shaped portions 12 is formed.
Has a depth and width of 0.5 mm and 2 mm, respectively,
It is formed continuously with the drainage port 3 (not shown) or the drain groove 5 (not shown) on the underwater side. In such a thin and deep flow channel, the viscous resistance of water is remarkably expressed as a flow velocity suppressing effect, and together with the effect of surface tension generated in the thin flow channel, the flow velocity in the flow channel 13 can be efficiently increased. Can be slowed down .

[0028] In Example 4 of the present applied invention, as shown in FIG. 9, by reducing forming a convex portion 12, the passage 13
Since the amount of polka dots that can remain independently on the upper surface of the convex portion 12 partitioned by the flow path 13 without flowing into the peripheral flow path 13 is about 0.2 CC, by any chance, Even if polka dots independently remain on the convex portion 12, even under the conditions of the above-mentioned bathroom environment, it is naturally dried more quickly, and the floor surface is dried more quickly. .

As described above, the convex shaped portions 12 having a rectangular basic shape are arranged vertically and horizontally and staggered in a staggered manner, and the flow passages 13 formed between them are finely changed in direction and branched to form a fine mesh shape. By arranging the flow path 13, the flow resistance in the flow path is increased, and when the water flows toward the lower side of the water, it passes through various routes, and as a result, the flow velocity of the drainage becomes slow and may be interrupted. It is supposed not to.

As shown in FIGS. 10 (a) and 10 (b), the cross-sectional shape of the flow channel 13 in the fourth embodiment is a substantially V-shaped flow channel in consideration of cleanability. In addition to this, as the cross-sectional shape of the flow path 13, FIGS.
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 depth of each shape in the cross-sectional shape of the flow channel 13 are defined by WD, respectively, as shown in FIGS. In this case, regardless of the cross-sectional shape of the flow path 13, FIG.
As shown in (b) and FIG. 11 (d), when the cross-sectional shape is changed to form a two-step shape or the like, the width of the flow path shape portion that can store a substantially minimum amount of water is It is assumed that the flow path width is W. Further, the shape and arrangement of the convex portion 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, a geometric pattern, or a different shape. Even in the combination, as a result of the size and path of the flow path 13 formed between the convex-shaped portions and the effect of the viscous resistance or surface tension of water generated in the flow path 13, as a result, the water is absorbed on the floor panel 1. When flowing, the polka dots formed on the surface are broken, and the flow velocity that makes it possible to temporarily capture the water that has flowed into the flow path 13 without interruption during the time until the polka dots disappear as long as they can produce a temporary slow to effect,
The arrangement, shape, and route do not matter.

Next, the operation of the present invention configured as described above will be described. First, in Example 1 and Example 2 ,
The water droplets formed by the use of water on the surface of the floor panel 1 spread and try to flow into the flow path 7 as shown by the imaginary line in FIG. This is due to the general physical phenomenon that polka dots are torn by the height difference of the unevenness on the floor surface and try to flow from the high convex part to the low concave part,
The convex portion 6 for preventing slippage and the convex-concave portion 8 for breaking the surface tension function to assist this action. The water flowing into the flow path 7 flows through the flow path 7 formed continuously and is drained directly to the drainage port 3 or via the drainage drain groove 5.

In the case of the conventional general floor, the material of the floor panel is a hydrophobic material such as plastic, and the material itself tries to repel water, and the drainage in the flow path is too good and the flow velocity is too high. If the polka dots are pushed into the flow channel 7 due to the effect of the surface shape of the floor due to the fact that the flow rate becomes too fast or the flow velocity becomes non-uniform, the water will flow in the flow channel 7 at an early stage. The phenomenon that the water drops off frequently occurs, and the water left behind remains stagnant, and as a result, the water poured on the floor panel 1 cannot completely destroy the form of the water dot and remains as an independent water dot. I tended to do it.

The uneven shape portion 8 of Embodiments 1 and 2
Reduces the surface tension of the polka dots, and has the effect of guiding the water into the flow path 7 and also resists the water that flows into the flow path 7 and tries to flow down , thereby slowing down the flow velocity of the water. It has the effect of slowing down the water in 7 and congesting it. As a result, it becomes possible to establish a water-filled state in which the inside of the flow path 7 is filled with the water that is connected, and since the water in the flow path 7 is drained only at a slow speed, the water-collected state can be maintained for a long time. Can hold. Therefore, even if the surface of the floor panel 1 is hydrophobic, as shown in FIG. 6 (b), the water flowing through the flow path 7 is not interrupted at an early stage, and the water is temporarily collected as described above. The state can be maintained for a long time.

From this state, new water is made to flow on the surface of the floor panel 1 due to a bathing action, etc. Even if the water once forms a water dot on the surface of the floor panel 1 due to the surface tension, these water dots are generated on the floor panel 1. Since it is in contact with the water in the temporarily trapped state already existing in the upper flow path 7, the action of attracting / conducting water in the flow path 7 and the above-mentioned anti-slip projections 6 and uneven shape parts Due to the synergistic effect of the surface tension breaking action of 8, the water in the polka dots gradually flows into the flow path 7 and is slowly but uninterruptedly guided to the drainage port 3 or the drainage drain groove 5 and reliably drained. . As a result, the water drops on the floor panel 1 disappear and do not remain on the floor panel 1.

The attraction / conducting action of the water temporarily captured in the flow path 7 utilizes the surface tension of the water.
Due to the surface tension, water tends to be spherical in order to minimize its surface area, and as a result, it becomes stable as a polka dot on a hydrophobic substance. However, when multiple polka dots that exist separately and stably under each surface tension come into contact with each other, it is better to form one large polka dot than to keep forming polka dots individually. Because of the smaller surface area and greater stability, these waters have a tendency to coalesce upon contact. This power is
It is due to the surface tension of each water, but even if it is a stagnant polka dot where external force is not working due to this,
It is possible to obtain the power to move due to the surface tension of the water itself at the moment of contact with other polka dots or water. In Example 1 and Example 2 , the water temporarily captured in the flow path 7 is brought into contact with the residual water that has newly formed a polka dot on the surface of the floor panel 1 to generate the surface tension of these two waters. The force is used as an attraction / water-conducting force into the flow path 7 and the remaining water drops are reduced to shorten the drying time of the surface of the floor panel 1.

The water that has flowed into the flow path 7 and is temporarily trapped is not completely stagnant, but is flowing slowly while the speed is suppressed. At the same time, the total amount of water temporarily captured in the flow path 7 on the floor panel 1 can be steadily reduced, and the floor panel 1 can be dried early. Even after the water has flowed through the channel 7 after a while, as shown in FIG. 6C, even if the water remains between the uneven portions 8, the residual water amount in this case is extremely small. , It evaporated in a short time,
There is no problem in actual use.

Further, the temporary water trapping state in the flow path 7 is mainly due to the fact that the waterdrops generated on the surface of the floor panel 1 are attracted to the flow path 7.
It should be held until the water is introduced, and even if the continuous state in the flow path 7 is partially interrupted at some part on the floor panel 1 before the water dot disappears, the water dot is actually touched. Channel 7
And the water under portion of the floor panel 1 is, if you are connected by a flow path 7 water catching state of any route, for water polka flows transmitted its path, thereby being drained, the present invention Does not impair the effect of. In addition, even if the water catching state in the channel 7 is interrupted immediately after the water drops disappear and water remains only in the channel 7, the remaining water is spread over a wide area on the floor panel 1. It exists in a diffused way,
It is easier to dry naturally than residual water in a polka dot state that remains independently, and does not impair the effects of the present invention.

In addition, the amount of water retained on the upper surface of the anti-slip convex portion on the floor panel divided by the flow path without contacting the water in the flow path is determined by the general ventilation conditions of the bathroom and the average. It is kept at a level of 2CC or less, which can be dried in a time of about 8 hours in a temperature and humidity environment. If the amount of water remaining is in this range, it can be naturally dried in the general bathroom environment from the time of bathing until the morning of the next day for about 8 hours. Even if polka dots remain, 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. Therefore, there is no problem.

Further, in Example 3 of the present invention shown in FIG. 7, the convex portion 10 having both the anti-slip effect and the surface tension breaking effect is formed on the entire surface of the floor panel 1, and the convex portion 10 The space is used as the flow path 11. The water that has flowed to the surface of the floor panel 1 is torn by the convex portion 10 and the flow path 11
It is pushed inside. In the flow path 11, as a flow velocity suppressing means, the flow path on the underwater side is bent in a direction that resists the drainage gradient, or the drainage gradient on the underwater side is loosened as compared with the other portions so that the drainage property on the downstream side is reduced. To reduce the flow rate, and the congestion in the drainage in the flow path 11 is blocked. Therefore, the flow path 1
The structure is such that the water in 1 does not break in the middle. In addition, as a method of controlling the drainage flow velocity in the flow channel 11, there is also a means for suppressing the speed of the drainage flowing in the flow channel 11 by providing fine unevenness in the flow channel 11 and making it an obstacle.

In general, the higher the drainage speed on the floor is, the more easily it is felt that the floor has good drainage. Therefore, the drainage flow path has been conventionally disclosed in JP-A-4-243941 . Various efforts have been made to improve the drainage performance of the interior, but especially on floors made of hydrophobic materials such as plastic, if the drainage speed is too fast, it will not be possible. , It is easy to break the drained water that is connected in a continuous state on the way, and as a result, water that is left behind is generated, so island-shaped isolated polka dot residual water occurs, and at first glance it seems that drainage is good Even if it looked like it, when I finally saw it, the floor was hard to dry. Therefore, in the third embodiment , the above-described first and second embodiments of the present invention are implemented.
As in Example 2 , the flow velocity in the flow path 11 is suppressed and the water in a part of the floor is made difficult to flow by the idea from the completely opposite viewpoint to the conventional technique, thereby improving the drainage and drying properties as a whole. The structure is adopted.

According to this, by providing a means for suppressing the flow velocity in the flow channel 11, a part of the water flowing on the floor panel 1 is once trapped in the flow channel 11 and is continuously connected by water. By forming the channel 11 of the above for a while, the water drops on the floor panel 1 can be attracted / conducted into the channel 11 to gradually destroy the water drops. Further, after that, the water on the surface is drained slowly and surely without interruption, and the water on the surface is drained, so that it is possible to surely reduce the moisture on the floor surface with the passage of time, and at the same time, on the floor panel 1. Dispersing water over a wide area promotes efficient natural drying and can significantly reduce the floor drying time.

In addition, the amount of water retained on the upper surface of the non-slip convex portion on the floor panel partitioned by the flow path without contacting the water in the flow path is determined by the general ventilation conditions of the bathroom and the average. It is kept at a level of 2CC or less, which can be dried in a time of about 8 hours in a temperature and humidity environment. If the amount of water remaining is in this range, it can be naturally dried in the general bathroom environment from the time of bathing until the morning of the next day for about 8 hours. Even if polka dots remain, 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. Therefore, there is no problem.

[0043] Further, according to the present invention shown in FIGS. 8 and 9
In Example 4 of the bathroom panel, the width and the depth of the flow passage 13 formed between the substantially rectangular convex portions 12 formed on the entire surface of the floor panel 1 are made narrower and deeper, so that the flow passage is formed. 1
The water in 3 is kept uninterrupted. This utilizes the effects of water viscous resistance and surface tension. Since the water itself has viscosity, the flow path 13 formed thin and deep.
Since the viscous resistance is likely to appear as a flow velocity suppressing effect in the inside, a sufficient flow velocity suppressing effect can be obtained. In addition to the effect of the surface tension generated in the thin and deep channel form, the water flow channel 1
The effect of temporarily catching water in 3 becomes higher, even if floor panel 1
Even if the material is a hydrophobic material that repels water, it is possible to temporarily collect water in the flow path 13 in a continuous state without repelling water.

Similarly, even in the case of flow passages arranged at a fine pitch or in the form of a mesh-like flow passage, viscous resistance is likely to appear when water flows down, and the flow passage 13 is continuously formed in the same manner as in the above-mentioned embodiment. It is possible to produce a flow velocity suppressing effect that makes it possible to temporarily capture water in a connected state.

Along with this, the amount of water retained on the upper surface of the anti-slip convex portion on the floor panel 1 partitioned by the flow path without contacting the water in the flow path is determined by the general ventilation conditions of the bathroom or It is kept at a level of 2CC or less, which can be dried in about 8 hours under an environment of average temperature and humidity. If the remaining amount of water in this range is in a general bathroom environment, it is possible to dry naturally for about 8 hours from the time of bathing to the morning of the next day. Therefore, as shown in FIG. Even if a polka dot that does not contact at all and remains independently, it is possible to suppress the amount of water to an amount that can be dried within a specified time, and it is possible to sufficiently achieve the object of the present invention. It doesn't matter at all. In Example 4 of FIG. 9, the amount of the anti-slip convex portion 12 is reduced to 0.
By reducing the amount to 2CC, we have achieved reliable drying in a shorter time.

It should be noted that the state in which the amount of water in the water drops remaining on the upper surface of the convex portion 12 on the floor panel 1 without contacting the water in the flow path 13 is 2 CC or less is a substantial state, In addition, even if the convex portion 12 in which an amount of water deviating from this condition can partially exist, it is substantially the same as long as the obtained floor drying effect does not change the gist of the present invention. .

As shown in FIG. 9, in the fourth embodiment, the convex portion 12 has a size of about 5 × about 10 mm, and is arranged so as to be vertically / horizontally and staggered, and the flow path 13 formed between them is formed.
Flow direction 1 in a fine mesh shape
By arranging 3, the flow resistance in the flow path is increased and various routes can be taken when the water flows downward. This is because even if the state of being connected and capturing water in the flow path 13 is partially interrupted,
It produces the effect that the water of the polka dots is surely drained through another route. In addition, the width of the convex portion 12 is set to about 5 mm and is formed to have a size close to the average droplet diameter of water droplets, so that the effect of destroying the water droplets can be enhanced and the water on the floor panel 1 flows with a high probability. Since it becomes possible to come into contact with the water in the channel 13 and it becomes difficult to exist as an independent dot on the convex portion 12, the amount of water that may unfortunately remain on the convex portion 12 is naturally dried. You can limit the range to just dry. In the case of the present embodiment, since the amount of water of about 0.2 CC or less can be independently present on the convex shape portion 12 by the above-mentioned device, more reliable waterdrop destruction and more reliable flooring. Realizes surface drying.

The water temporarily trapped while being connected to the inside of the flow path 13 by utilizing the effect of suppressing the flow velocity and the effect of the surface tension produces the same action as that of the above-described embodiment of the present invention, and FIG.
As shown in FIG. 2, it becomes possible to attract / conduct polka dots in the flow path 13 and drain them without leaving any residue, and as a result, the floor can be dried early with the same effect as the present invention.

[0049]

As described above, according to the present invention, the surface of the bathroom floor panel is provided with the projections for preventing slippage and destroying the surface tension of the polka dots, and the drainage port or the sink groove between these projections. Since a continuous flow path is formed toward and the means for slowing the flow velocity in the flow path to prevent the water in this flow path from being interrupted, the water on the floor surface is not interrupted. It can be drained and the floor drying performance can be improved.

Further, in the bathroom floor panel of the present invention, by controlling the flow velocity of the water in the flow path, a part of the water flowing on the floor surface is temporarily captured while being connected to the flow path, Since the amount of water that can independently remain on the upper surface of the anti-slip convex portion divided by the passage without touching the temporarily captured water in the flow passage is set to 2 CC or less, it remains independently on the convex portion. Since the amount of water that may be lost can be limited to the amount that can be naturally dried within a specified time in a general bathroom environment, the floor drying performance can be reliably guaranteed.
