Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathroom floor, and more particularly to a bathroom floor that can improve drainage and drying properties by minimizing hot water remaining in a washing area, and can prevent slipping on the floor surface.
[0002]
[Prior art]
In recent residences and the like, so-called system buses and the like in which bathrooms are unitized are becoming mainstream, and the bathroom floors of these system buses and the like are composed of FRP or the like. Such an FRP bathroom floor has a low surface tension due to its nature, so that hot water after bathing tends to remain as relatively large water droplets, and thus mold and the like are likely to occur. There is a problem that the floor becomes slippery. Then, as a well-known bathroom floor, the form disclosed by patent document 1 which improved the drying property of the floor surface, and the form disclosed by patent document 2 which can suppress the slip of a floor surface exist.
[0003]
The bathroom floor of Patent Document 1 is formed with a plurality of protrusions having a vertically and horizontally long rectangular shape with a planar shape of 5 mm × 10 mm, a width of 2 mm, and a depth of 0. And a groove of 5 mm. In such a form, when hot water flows due to the water gradient of the floor surface, water droplets on the floor surface are divided by the respective convex portions, and the water droplets on the convex portions are attracted to the grooves, and the inside of the grooves It is possible to improve the drying property of the floor by preventing large water droplets from remaining.
Moreover, the bathroom floor of the said patent document 2 becomes a structure which provides a groove | channel with a fine pitch only in a bathtub and the entrance / exit vicinity area | region, and provides a groove with a rough pitch in the area | region other than that, and forms two types of convex parts. Yes.

[Problems to be solved by the invention]
However, in the form of Patent Document 1 described above, the water gradient is formed by curving the floor surface toward the drain outlet formed in one place on the bathroom floor, so that the region where the water gradient is gentle is partially Will occur. In addition, since the flat area of each convex portion is the same in the entire floor area, that is, the length of the groove per unit area is constant, the amount of hot water that can be poured into the groove per unit area is uniform. The hot water in the groove in the region where the water gradient is gentle becomes difficult to flow, and the force of the groove to attract the hot water is weakened. As a result, water droplets are likely to remain in a region where the water gradient is gentle, resulting in inconvenience that the drying property of the entire floor surface cannot be sufficiently improved.
[0006]
Here, if the water gradient of the floor surface is increased as a whole, or if the length of the groove is increased by reducing the flat area of each convex portion, the hot water in the groove can be made easier to flow. In this case, the flow rate of the hot water flowing in the groove on the entire floor surface becomes too high, and the force that the groove attracts the hot water is reduced, resulting in another inconvenience that water droplets easily remain.
[0007]
Moreover, in the form of patent document 2, although the slip of the area | region near a bathtub and an entrance / exit can be prevented certainly, in other areas, a water droplet remains and implement | achieves the slip prevention in the whole bathroom floor. Inconvenience that you can not.
[0008]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and the purpose of the present invention is to ensure that the hot water on the convex portion is poured into the groove in the entire washing area, thereby improving the drying property. An object of the present invention is to provide a bathroom floor that can make the washing area difficult to slip.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a resin product provided with a washing area including a plurality of convex portions formed on a surface and a groove formed between adjacent convex portions and communicating with a predetermined drainage port. In the bathroom floor
The convex portion is made that a flat area with a flat area of at least magnitude two in the 6～220Mm ^2,
The groove has a width of 0.5 to 3 mm and a depth of 0.3 to 1.5 mm.
The washing area includes a first region including a convex portion having a large flat area, and a second region including a convex portion having a flat area smaller than the convex portion of the first region,
A second region is disposed so as to surround the first region, and the second region has a convex portion that constitutes the second region continuously bordering the outer periphery of the first region. Arranged to be arranged . According to such a configuration, the second region having many grooves per unit area is formed around the first region having few grooves per unit area on the floor surface. That is, since the amount of hot water that can be poured into the grooves of the first and second regions is different, the hot water easily flows toward the second region, and the second region uses the hot water in the first region. A so-called pumping action such as pulling can be exhibited. Therefore, even when the washing area includes an area having a gentle water gradient, the pumping action can be exerted by arranging the second area in the area. It becomes possible to maintain the drainage speed of flowing hot water moderately, stabilize the force of attracting hot water into the groove by capillary action, and improve the drying effect. In addition, since the convex part is composed of at least two types of large and small flat areas, it is possible to give a tight design to the washing area without partially changing the groove width, and suction of water A pattern groove or the like having a width of about 5 mm, which is less effective, is unnecessary.
Here, when the flat area of the convex portion is less than 6 mm ² , water droplets on the plurality of convex portions are easily collected and remain as large water droplets, and even if the flat area of the convex portion exceeds 220 mm ^2. Large water droplets that are difficult to dry on the convex portions tend to remain.
Further, when the groove width is less than 0.5 mm, dirt is accumulated in the groove, causing water repellency in the groove and making it difficult for hot water to flow in the groove, making it difficult to remove the dirt. On the other hand, if the groove width exceeds 3 mm, the effect of capillary action that attracts hot water on the convex portion into the groove is lost.
In addition, if the groove depth is less than 0.3 mm, the effect of the capillary phenomenon is lost. On the other hand, if the groove depth exceeds 2.0 mm, the attracting effect is high, but dirt is deposited on the bottom. It becomes extremely difficult to perform cleaning.
Here, it is preferable to set the groove width to 1.0 to 2.0 mm and the groove depth to 0.5 to 1.0 mm. According to such a range, there is an advantage that the effect of the capillary phenomenon can be further improved while maintaining the ease of cleaning in the groove.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In the present invention, a configuration in which the first areas are arranged in a scattered manner in the washing area is also preferably employed. If such a structure is taken, since the 1st and 2nd area | region where the plane areas of each convex part differ is scattered, moderate friction resistance is provided to a bather's sole in the whole washing area. It is possible to effectively prevent slipping of the foot.
Moreover, you may employ | adopt the structure of providing the intermediate | middle area | region which consists of a medium shape convex part between said 1st area | region and 2nd area | region.
[0012]
Furthermore, the said convex part can take the structure that it is provided in at least 1 planar shape of a substantially polygon, a substantially circle, and a substantially ellipse. In such a configuration, the formation edge of the convex portion can be directed in various directions, and no matter which direction the foot is directed, a frictional resistance can be imparted to the sole and slipping can be prevented. Further, the groove also extends in various directions, and the drainage speed in the groove can be adjusted.
