Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bathroom washing place and a method for producing the same. In particular, the present invention provides a bathroom washing place that can reduce residual water in the washing place and shorten the time for drying the surface of the washing place.
[0002]
[Prior art]
Conventionally, as a method for reducing the amount of water remaining in the washing area and shortening the water drying time of the washing area, there has been a method in which the shape of the washing area is devised and grooves are provided as described in JP-A-2002-54295. It was. That is, a non-slip convex portion is formed on the surface, and a flow path continuous to the drain port or the sink groove is formed between these convex portions, and at least the concave and convex shape portion that destroys the surface tension of the polka dots is superimposed on the flow channel By being formed, the flow rate of the water flowing in the flow path is suppressed, so that the water is not interrupted and remains in an island shape, and the floor surface can be dried in a shorter time.
[0003]
In addition, as another prior art, by making the surface of the washing area hydrophilic, the water on the surface of the washing area is spread in a thin film shape to prevent the water from being interrupted and remaining in an island shape, and the washing area has a gradient. There was a method in which the amount of residual water was reduced by the flow of water along the gradient, and the water drying time on the surface of the washing place could be shortened because the water spread in a thin film.
[0004]
[Problems to be solved by the invention]
However, a non-slip convex portion is formed on the surface, and a flow path continuous to the drain port or the sink groove is formed between the convex portions, and at least a concave-convex shape portion that destroys the surface tension of the polka dots is superimposed on the flow channel. The forming method has a problem that it takes time to clean the surface of the washing place such as the groove because the groove for the flow path is provided. In addition, in order to change the surface shape of the washing place in order to do so, it was necessary to newly or remodel the washing place mold.
[0005]
The method of making the surface of the washing area hydrophilic is that when a large amount of water is flowed to the washing area, the water spreads in a thin film on the surface of the washing area, but it does not become an image of drying unless time passes, so it is easy to understand visually, The problem was to provide an efficient water-drying surface for the washing area.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention provides a washing place provided with a gradient so that water flows toward the drain outlet, and the surface of the washing place is partitioned into a hydrophilic portion and a hydrophobic portion, and the hydrophilic portion is a drain outlet. Is formed so as to communicate with each other. By adopting such a configuration, it is possible to reduce the amount of initial residual water on the surface of the washing place without forming a groove through which water flows, and it is easy to understand visually, and the efficiency of water drying on the surface of the washing place can be improved. .

And are formed so as to communicate with each other.
[0008]
And since the hydrophilic part has the property to be compatible with water, the surface tension of water is weakened and the water tends to spread into a thin film, while the hydrophobic part has the property of repelling water by the surface tension of water. Therefore, the water in the hydrophobic part has a force to go to the hydrophilic part, and the hydrophilic part is formed so as to communicate with the drainage port, so the water in the hydrophilic part flows away to the drainage port. As a result, a large amount of water flowed to the washing area spreads in a thin film only at the hydrophilic portion, and the hydrophobic portion can be dried without getting wet with water. If it does in this way, while being able to reduce the amount of initial residual water on the surface of a washing place, it is easy to understand a dry state visually, and the efficiency of water drying of the surface of a washing place can be improved.
[0009]
In the invention according to claim 2 of the present invention, the hydrophilic portion of the surface of the washing place is more widely defined according to the gradient from high to low.
[0010]
And the hydrophilic part of the surface forms a wider area according to the gradient from the high place to the low place, so that the water flow on the surface of the washing place can be surely drained smoothly.
[0011]
In the invention according to claim 3 of the present invention, the hydrophilic portion is formed by partitioning the hydrophilic material by forming a coating film on the surface of the washing place.
[0012]
And the hydrophilic part is a simple structure that forms a hydrophilic material by forming a coating film on the surface of the washing place, and can reduce the initial residual water amount on the surface of the washing place. The efficiency of water drying can be improved.
[0013]
The invention according to claim 4 of the present invention is configured such that at least one width of the width for forming the hydrophobic portion is defined to be smaller than the size of the water droplet that should not remain.
[0014]
And since the water droplet of the magnitude | size beyond the width | variety which divides and forms a hydrophobic part does not remain on the washing field surface, it can improve the water drying efficiency of the washing field surface.
[0015]
The invention according to claim 5 of the present invention comprises a step of press-molding the SMC material using a mold, a step of partitioning the hydrophilic portion and the hydrophobic portion, and a step of coating the hydrophilic material on the surface of the washing place. is there.
[0016]
In the invention according to claim 6 of the present invention, the step of partitioning the hydrophilic portion and the hydrophobic portion and the step of coating the hydrophilic material on the surface of the washing place are constituted by a single step by silk printing.
[0017]
And by these construction methods, it is possible to reduce the initial residual water amount on the surface of the washing place without forming a water flow groove, and it is easy to understand visually, and the efficiency of water drying on the surface of the washing place can be improved.
