【発明の属する技術分野】
本発明は浴室用洗い場およびその製造方法に関わるもので、特に洗い場の残水を少なくし、洗い場表面の水乾き時間を短縮することのできる浴室用洗い場を供するものである。
【０００２】
【従来の技術】
従来、洗い場の残水を少なくし、洗い場表面の水乾き時間を短縮する方法として特開２００２−５４２９５公報に記載されているように洗い場表面の形状を工夫し、溝を設ける方式のものがあった。すなわち、表面に滑り止め用の凸部とこれら凸部の間に排水口または流し溝に連続する流路が形成され少なくとも該流路の上に水玉の表面張力を破壊する凹凸形状部が重ねて形成されることにより、流路内を流れる水の流速を抑制し途中で水が途切れて島状に残ることがなくなり、より短時間で床の表面乾燥が可能になるというものである。
【０００３】
また、別の従来技術として、洗い場表面を親水性とすることにより、洗い場表面の水を薄い膜状に広がらせ水が途切れて島状に残ることを防止し、洗い場に勾配が設けてあるのでその勾配に沿って水が流れてゆくことにより残水量を少なくし、薄い膜状に水が広がっているので洗い場表面の水乾き時間を短縮することができるという方式があった。
【０００４】
【発明が解決しようとする課題】
しかしながら、表面に滑り止め用の凸部とこれら凸部の間に排水口または流し溝に連続する流路が形成され少なくとも該流路の上に水玉の表面張力を破壊する凹凸形状部が重ねて形成する方法は、流路の為の溝を設けてあるので、溝などの洗い場表面のお手入れに手間がかかるという課題があった。また、そのようにするためには洗い場表面形状を変更する為、洗い場の金型を新規または改造する必要があった。
【０００５】
洗い場表面を親水性とする方法は、洗い場に多量の水を流した場合、洗い場表面に水が薄い膜状に広がるが、時間が経たないと乾燥というイメージにならないので、見た目にも解り易く、洗い場表面の水乾きの効率の良いものを提供するということが課題であった。
【０００６】
【課題を解決するための手段】
本発明は上記課題を解決するめに、排水口に向かって水が流れるように勾配が設けられた洗い場において、前記洗い場の表面が親水部分と疎水部分とに区画形成され、前記親水部分は、排水口に向かって連通するように区画形成すると共に、高い所から低いところへの勾配に従ってより幅広く区画形成したものである。このような構成にすることにより、水の流れる溝を構成することなく洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。そして、洗い場表面の水の流れを確実にしかつスムーズに排水することができる。
【０００７】
【発明の実施の形態】
本発明の請求項１にかかる発明は、排水口に向かって水が流れるように勾配が設けられた洗い場において、表面が親水部分と疎水部分とに区画形成され、前記親水部分は排水口に向かって連通するように区画形成されるように構成したものである。
【０００８】
そして、親水部分は水と馴染む性質があるので、水の表面張力は弱められ水が薄い膜状に広がろうとするが、疎水部分は水の表面張力により水を弾こうとする性質になる。そこで、疎水部分にある水は親水部分へ行く力が働き、かつ親水部分は排水口に向かって連通するように区画形成されているので親水部分にある水は排水口に流れ去るので、その結果として洗い場に流された多量の水は親水部分のみ薄い膜状に広がり、疎水部分は水に濡れずに乾燥しているという状態にすることができる。このようにすると、洗い場表面の初期残水量を減らすことができるとともに、見た目にも乾燥状態が解り易く、かつ洗い場表面の水乾きの効率を良くすることができる。
【０００９】
また、洗い場表面の親水部分は高い所から低いところへの勾配に従ってより幅広く区画形成したものである。
【００１０】
そして、表面の親水部分は高い所から低いところへの勾配に従ってより幅広く区画形成することにより、洗い場表面の水の流れを確実にしかつスムーズに排水することができる。
【００１１】
本発明の請求項２にかかる発明は、親水部分は、親水材料を洗い場表面に塗膜を構成することにより区画形成されて構成したものである。
【００１２】
そして、親水部分は、親水材料を洗い場表面に塗膜を構成することにより区画形成するという簡単な構成で、洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。
【００１３】
本発明の請求項３にかかる発明は、金型を用いＳＭＣ材料をプレス成形する工程と、親水部分と疎水部分を区画する工程と、親水材料を洗い場表面に塗装する工程とから構成したものである。
【００１４】
本発明の請求項４にかかる発明は、親水部分と疎水部分を区画する工程と親水材料を洗い場表面に塗装する工程が、シルク印刷により一度の工程で構成したものである。
【００１５】
そして、これらの工法により、水の流れる溝を構成することなく洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。
【００１６】
【実施例】
以下、本発明の実施例について図面を用いて説明する。
（参考例１）
図１の浴室内の斜視図に示すように、浴室は、浴槽、洗い場、壁、窓、天井、扉、鏡、水栓、換気扇などの部材を組み合わせることにより構成される。洗い場１は、排水口２に向かって水が流れるように勾配が設けられている。図２は、図１で示した洗い場表面の部分平面図であり、親水部分３と疎水部分４とに区画形成してあり、前記親水部分３は排水口１に向かって連通するように区画形成されている。図３は、その断面図（ａ）と水滴５がきた場合の流れの様子を示した模式図（ｂ）、（ｃ）である。水滴５において、親水部分３は水と馴染む性質があるので、水の表面張力は弱められ水が薄い膜状に広がろうとし、疎水部分４は水の表面張力により水を弾こうとする性質になる。そこで、疎水部分４にある水は親水部分３へ行く力が働き、かつ親水部分３は排水口に向かって連通するように区画形成されているので親水部分３にある水は排水口１に流れ去るので、その結果として図３（ｃ）のようになり洗い場に流された多量の水は親水部分のみ薄い膜状に広がった状態になる。そして、疎水部分４で区画整理された部分は水に濡れずに乾燥しているという状態にすることができる。
【００１７】
このように、洗い場表面を全面親水状態にするのと較べ、水は親水部分のみ薄い膜状に広がった状態になるので、洗い場表面の初期残水量はその面積比に比例して減らすことができる。初期残水量を少なく出ることと水が薄い膜状に広がっていることにより、洗い場表面の水乾きの効率を良くすることができる。さらに、疎水部分において水が弾き排水口へ水が流れる様子が目視できることにより、見た目にも乾燥状態を解り易くすることができる。
【００１８】
図２に親水部分と疎水部分とを区画形成した一例を示したが、図４に示した親水部分３’と疎水部分４’の様に区画形成することもできるし、親水部分が排水口に向かって連通するように区画形成されていればその他様々なパターンで区画を形成しても本例で示した作用効果が得られるものである。
【００１９】
本例では洗い場表面に滑り止めの凹凸の無い状態で図示しているが、適時滑り止めの凹凸を設けることができ、本例で示したものと同様の作用効果が得られる。また、洗い場表面に全く溝の無い状態でも実施可能であるが、洗い場表面に排水性能を向上させる為の複数の溝を配設することもできる。
【００２０】
また、洗い場表面の親水部分の面積比としては、親水部分が洗い場表面全体の５％以上５０％以下にすることが望ましい。
（実施例１）
本発明の実施例である図５の洗い場表面の部分平面図に示すように、洗い場表面の親水部分６は勾配の高い所から低いところへ、勾配に従ってより幅広く区画形成した。このように区画形成することにより、洗い場表面の水の流れを確実にしかつスムーズに排水することができる。
（実施例２）
次に具体的な製造方法について述べる。既知の方法で金型を用いＳＭＣ（シートモールディングコンパウンド）材料をプレス成形し排水口に向かって水が流れるように勾配が設けられた洗い場として形状を付与した成形体を得る。ＳＭＣ材料自体が水を弾く性質があり洗い場表面全体が疎水部分の状態になっている。次に、目的とする疎水部分をマスキングフィルムなどにより区画し塗料が予めかからないようにするとともに、親水部分は排水口に向かって連通するように区画する。次に、親水材料を含む塗料を洗い場表面に塗装し硬化させ、洗い場表面に約２０μｍの親水性の塗装膜を構成する。その後マスキングフィルムを剥がして目的とする浴室用洗い場を得る。このようにして得られた洗い場は、実施例１で述べた作用効果を得ることができる。
（実施例３）
スクリーンを用い、予め設計した親水部分と疎水部分を親水部分は排水口に向かって連通するように区画し、疎水部分はインクが通らない様にし、親水部分はインクが通るようにする。次に、このスクリーンを用い、スクリーン印刷の手法を用いインクを親水材料からなるインクにしておき印刷の後硬化させ目的とする浴室用洗い場を得る。
【００２１】
製造方法について、具体的な２実施例について述べたが親水部分と疎水部分とに区画形成され、前記親水部分は排水口に向かって連通するように区画形成できる方法であればいずれの方法でも良い。
【００２２】
また、本発明に付加的に洗い場の裏面に加熱手段を装着させ洗い場表面の水乾きをさらに効率の良く早めることもできる。
【００２３】
【発明の効果】
以上説明したように本発明の請求項１に係る発明により、洗い場に流された多量の水は親水部分のみ薄い膜状に広がり、疎水部分で区画整理された部分は水に濡れずに乾燥しているという状態にすることができる。このようにすると、洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。
【００２４】
また、表面の親水部分は高い所から低いところへの勾配に従ってより幅広く区画形成することにより、洗い場表面の水の流れを確実にしかつスムーズに排水することができるという効果が得られる。
【００２５】
また、請求項２に係る発明により、親水部分は、親水材料を洗い場表面に塗膜を構成することにより区画形成するという簡単な構成で、洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。
【００２６】
また、請求項３および４に係る発明の工法により、水の流れる溝を構成することなく洗い場表面の初期残水量を減らすことができるとともに、見た目にも解り易く、洗い場表面の水乾きの効率を良くすることができる。

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 a concave-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 problems, the present invention provides a washing place in which a gradient is provided so that water flows toward a drain outlet, and the surface of the washing place is partitioned into a hydrophilic part and a hydrophobic part, The section is formed so as to communicate with the mouth, and the section is formed more widely according to the gradient from the high place to the low place . 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 the water flow on the surface of a washing place can be ensured and drained smoothly.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
According to the first aspect of the present invention, in a washing place provided with a gradient so that water flows toward the drain port, the surface is partitioned into a hydrophilic portion and a hydrophobic portion, and the hydrophilic portion faces the drain port. 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]
Also, the hydrophilic portion of the wash had field surface is a more broadly defined and formed in accordance with the gradient of the lower to where from a high place.
[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
[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. Ru can be used to improve the efficiency of water dry.
[0013]
The invention according to claim 3 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.
[0014]
In the invention according to claim 4 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.
[0015]
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.
[0016]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
( Reference Example 1 )
As shown in the perspective view in the bathroom of FIG. 1, the bathroom is configured by combining members such as a bathtub, a washing place, a wall, a window, a ceiling, a door, a mirror, a faucet, and a ventilation fan. The
[0017]
In this way, compared to making the entire surface of the washing area hydrophilic, water is in a state where only the hydrophilic portion spreads in a thin film, so that the initial residual water amount on the surface of the washing area can be reduced in proportion to the area ratio. . Since the amount of the initial residual water is reduced and the water spreads in a thin film shape, the efficiency of drying the surface of the washing place can be improved. Furthermore, it is possible to make it easy to understand the dry state by visually observing the manner in which water repels in the hydrophobic portion and the water flows to the drain outlet.
[0018]
FIG. 2 shows an example in which a hydrophilic part and a hydrophobic part are partitioned, but it can also be formed like the hydrophilic part 3 ′ and the hydrophobic part 4 ′ shown in FIG. If the compartments are formed so as to communicate with each other, the effects shown in this example can be obtained even if the compartments are formed in various other patterns.
[0019]
In this example , the surface of the washing area is illustrated without the non-slip unevenness, but the anti-slip unevenness can be provided at the appropriate time, and the same effects as those shown in this example can be obtained. Although it is feasible even in the absence of a completely groove in washing area surface, Ru can also be arranged a plurality of grooves for improving the drainage performance washing area surface.
[0020]
Also, as the area ratio of the hydrophilic portion of the washing area surface, it is desirable that the hydrophilic portion is 50% or less than 5% of the total washing space surface.
( Example 1 )
As shown in the partial plan view of the washing surface in FIG. 5 which is an embodiment of the present invention, the hydrophilic portion 6 of the washing surface was partitioned more widely according to the gradient from a high gradient area to a low gradient area. By forming the compartments in this way, the water flow on the surface of the washing place can be surely drained smoothly.
( Example 2 )
Next, a specific manufacturing method will be described. Using a mold, a SMC (sheet molding compound) material is press-molded by a known method to obtain a molded body having a shape as a washing place provided with a gradient so that water flows toward the drain port. The SMC material itself has a property of repelling water, and the entire surface of the washing place is in a hydrophobic portion state. Next, the target hydrophobic portion is partitioned with a masking film or the like so that the coating is not applied in advance, and the hydrophilic portion is partitioned so as to communicate with the drain port. Next, a paint containing a hydrophilic material is applied to the surface of the washing place and cured to form a hydrophilic coating film of about 20 μm on the surface of the washing place. Then, the masking film is peeled off to obtain the desired bathroom washing place. The washing place thus obtained can obtain the effects described in the first embodiment.
( Example 3 )
A screen is used to partition a previously designed hydrophilic portion and hydrophobic portion so that the hydrophilic portion communicates toward the drain port, the hydrophobic portion is prevented from passing ink, and the hydrophilic portion is allowed to pass ink. Next, using this screen, the ink is made of a hydrophilic material using a screen printing technique, and is cured after printing to obtain a desired bathroom washing place.
[0021]
As for the manufacturing method, two specific examples have been described, but any method may be used as long as it is a method in which a hydrophilic portion and a hydrophobic portion are partitioned and the hydrophilic portion can be partitioned so as to communicate with the drain port. .
[0022]
Further, in addition to the present invention, a heating means can be attached to the back surface of the washing place, so that the water drying of the washing place surface can be accelerated more efficiently.
[0023]
【The invention's effect】
As described above, according to the invention according to
[0024]
In addition, by forming the hydrophilic portion on the surface more widely in accordance with the gradient from the high place to the low place, the flow of water on the surface of the washing place can be ensured and drained smoothly.
[0025]
Further, according to the invention according to
[0026]
In addition, the method of the invention according to claims 3 and 4 can reduce the amount of initial residual water on the surface of the washing place without forming a groove for flowing water, and it is easy to understand visually, and the efficiency of drying the surface of the washing place is improved. Can be better.
