Description

本発明は、浴室に関するものである。   The present invention relates to a bathroom.

従来より、浴室の床として防水性を有するFRP(繊維強化プラスチック)等の材質からなる防水床パンが用いられ、岩肌模様や石目模様をその表面に形成して意匠性を向上させている。しかし、排水性が悪いと、防水床パンの表面に島状に残水し、長時間経過しても自然乾燥しないという問題があった。そこで、直線状の親水部分と直線状の撥水部分とが平行に接して配置され、親水部分が排水口に連続した浴室床(例えば、特許文献1参照)が提案されている。この浴室床は、親水部分に薄い水膜を形成させることで床表面の残水をより短時間で自然乾燥させることできる。また、乾燥昇温した空気を床部材に供給する換気暖房型浴室(例えば、特許文献2参照)も知られている。   Conventionally, a waterproof floor pan made of a material such as FRP (fiber reinforced plastic) having a waterproof property has been used as a bathroom floor, and a rock texture pattern or a stone pattern is formed on the surface to improve the design. However, if the drainage is poor, there is a problem that water remains in an island shape on the surface of the waterproof floor pan and does not dry naturally even after a long time. In view of this, a bathroom floor in which a linear hydrophilic portion and a linear water-repellent portion are arranged in parallel with each other and the hydrophilic portion is continuous with a drain port (see, for example, Patent Document 1) has been proposed. This bathroom floor can naturally dry the remaining water on the floor surface in a shorter time by forming a thin water film in the hydrophilic portion. There is also known a ventilation / heating type bathroom (for example, see Patent Document 2) that supplies air heated to dryness to a floor member.

ところで、床表面の残水は石鹸垢や皮脂、湯垢等の汚染物質を含んでいる場合がある。この場合には特許文献1または特許文献2のように床表面の残水を乾燥させたとしても、床表面から汚染物質を除去することができず、床表面への汚れの付着、これに起因する悪臭等の問題がある。この問題を解決するために、排水口に向かって傾斜し、撥水機能を表面に有する浴室床が知られている。この浴室床は勾配を利用して床表面の残水を排水口に自動排水させるものであるが、体積の小さな水滴は床の勾配だけでは流れきらず床表面にとどまり、結果として汚染物質を十分に除去することができない。

By the way, residual water on the floor surface may contain contaminants such as soap stains, sebum, and scales. In this case, even if the residual water on the floor surface is dried as in Patent Document 1 or Patent Document 2, contaminants cannot be removed from the floor surface, and dirt is attached to the floor surface. There are problems such as bad odor. In order to solve this problem, a bathroom floor that is inclined toward a drain outlet and has a water repellent function on the surface is known. This bathroom floor uses the gradient to automatically drain the residual water on the floor surface to the drain, but the small volume of water droplets does not flow only on the floor gradient but stays on the floor surface, resulting in sufficient contamination. It cannot be removed.

本発明は、以上の通りの事情に鑑みてなされたものであり、浴室床表面の残水を容易に除去することができ、防汚性を向上させた浴室を提供することを課題としている。   This invention is made | formed in view of the situation as mentioned above, and makes it the subject to provide the bathroom which can remove the residual water of the bathroom floor surface easily and improved antifouling property.

本発明の浴室は、上記の課題を解決するために、以下のことを特徴とする。   In order to solve the above problems, the bathroom of the present invention is characterized by the following.

第1には、排水口を備えた浴室床と、前記浴室床に向けて給配水し浴室床上全面に水膜を形成させる給配水手段とを有し、浴室床は表面に撥水機能を有しており、浴室床上の水が途切れずに連続的に排水口に排水される浴室であって、前記給配水手段は、前記排水口の時間当たりの排水量を超える量の水を給配水するものであることを特徴とする。
第2には、排水口を備えた浴室床と、前記浴室床に向けて給配水し浴室床上全面に水膜を形成させる給配水手段とを有し、浴室床は表面に撥水機能を有しており、浴室床上の水が途切れずに連続的に排水口に排水される浴室であって、前記排水口を閉塞する開閉部材が設けられ、この開閉部材で前記排水口を閉じ、その状態で給配水手段から給配水されることを特徴とする。
First, the bathroom floor has a drainage floor and water supply / distribution means for supplying and distributing water toward the bathroom floor and forming a water film on the entire surface of the bathroom floor. The bathroom floor has a water repellent function on the surface. And the water on the bathroom floor is continuously drained to the drain outlet without interruption, and the water supply / distribution means supplies and distributes water exceeding the drainage amount per hour of the drain outlet. It is characterized by being.
Secondly, it has a bathroom floor with a drainage outlet and water supply / distribution means for supplying and distributing water toward the bathroom floor and forming a water film on the entire surface of the bathroom floor. The bathroom floor has a water repellent function on the surface. And the bathroom floor is continuously drained to the drain without interruption, provided with an opening / closing member that closes the drain, and the drain opening is closed with the opening / closing member. It is characterized in that the water is supplied and distributed from the water supply and distribution means.

第3には、第1又は第2の発明において、給配水手段は、浴室床を囲む浴室壁の下部に設けられた配水管であることを特徴とする。 Thirdly , in the first or second invention, the water supply / distribution means is a water distribution pipe provided at a lower part of a bathroom wall surrounding the bathroom floor.

第4には、第1ないし第3のいずれかの発明において、浴室床は、水に対する接触角が70°以上の撥水機能を表面に有するものであることを特徴とする。 Fourth , in any one of the first to third inventions, the bathroom floor has a water repellent function having a contact angle with water of 70 ° or more on the surface.

第5には、第1ないし第4のいずれかの発明において、浴室床表面に、排水口を中心として放射状に延びる凹溝が形成されていることを特徴とする。 Fifth , in any one of the first to fourth inventions, a concave groove extending radially about the drain outlet is formed on the bathroom floor surface.

第1又は第2の発明によれば、浴室床は表面に撥水機能を有していることにより、浴室床上の水が移動しやすくなる。このような撥水機能を表面に有する浴室床に向けて給配水し浴室床上全面に水膜を形成させることで、浴室床上の水が途切れずに連続的に排水口に排水され、浴室床上に水滴がほとんど残らない。したがって、浴室使用後、石鹸垢や皮脂、湯垢等の汚染物質を含む残水が浴室床表面に残っていても、浴室床上全面に水膜を形成するように水を給配水してこれを排水することにより、浴室床表面の残水が給配水した水と共に排水されて石鹸垢や皮脂、湯垢等の汚染物質が効果的に除去されるため、防汚性が向上する。 According to the 1st or 2nd invention, the water on a bathroom floor becomes easy to move because the bathroom floor has a water-repellent function on the surface. By supplying and distributing water toward the bathroom floor having such a water repellent function on the surface, a water film is formed on the entire surface of the bathroom floor, so that the water on the bathroom floor is continuously drained to the drain outlet without interruption. Almost no water droplets remain. Therefore, after using the bathroom, even if residual water containing contaminants such as soap stains, sebum, and scale remains on the bathroom floor surface, water is supplied and distributed so as to form a water film on the entire bathroom floor. By doing so, the residual water on the bathroom floor surface is drained together with the water supplied and distributed, and contaminants such as soap stains, sebum, and scales are effectively removed, thereby improving the antifouling property.

第3の発明によれば、給配水手段を特定することで、上記発明の効果を大きく向上させることができる。 According to 3rd invention, the effect of the said invention can be improved greatly by specifying a water distribution means.

第4の発明によれば、浴室床が、水に対する接触角が70°以上の撥水機能を表面に有するものであることにより、浴室床上の水が排水口に向かってより流れやすくなって一層効果的に排水される。したがって、排水後の浴室床上の水滴量はさらに低減したものとなる。 According to the fourth invention, the bathroom floor has a water-repellent function with a water contact angle of 70 ° or more on the surface, so that the water on the bathroom floor is more likely to flow toward the drain. Drained effectively. Therefore, the amount of water droplets on the bathroom floor after draining is further reduced.

第5の発明によれば、浴室床表面に、排水口を中心として放射状に延びる凹溝が形成されていることにより、排水時には、浴室床上の水がこの凹溝を通じて排水口に向かって連続する流路となって排水される。したがって、浴室床上の水がより効果的に排水され、排水後の浴室床上の水滴量はさらに低減したものとなる。 According to the fifth aspect of the present invention, the groove on the bathroom floor surface that extends radially around the drain outlet is formed, so that water on the bathroom floor continues toward the drain through the groove when draining. It drains as a flow path. Therefore, the water on the bathroom floor is drained more effectively, and the amount of water droplets on the bathroom floor after draining is further reduced.

以下に、図面に基づいて本発明の実施形態について説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図1は本発明の一実施形態に係る浴室の概略構成図であり、図2はその浴室の給配水手段の設置構造を示す断面図である。   FIG. 1 is a schematic configuration diagram of a bathroom according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing an installation structure of water supply / distribution means in the bathroom.

本実施形態に係る浴室は、図1及び図2に示すように、浴室床1、浴槽3、両側壁4a,4b、外壁5、ドア61を備えた出入口壁6、天井7等で浴室が構成されている。浴室床1には浴槽3側の略中央の位置に排水口8が設けられており、洗体時の汚染水等がこの排水口8から外部に排水されるようになっている。   As shown in FIGS. 1 and 2, the bathroom according to the present embodiment is composed of a bathroom floor 1, a bathtub 3, both side walls 4 a and 4 b, an outer wall 5, an entrance wall 6 having a door 61, a ceiling 7, and the like. Has been. The bathroom floor 1 is provided with a drain port 8 at a substantially central position on the bathtub 3 side, and contaminated water and the like during washing is drained from the drain port 8 to the outside.

さらに本実施形態に係る浴室は、浴室床1に向けて給配水する給配水手段2を有すると共に、浴室床1は表面に撥水機能を有する。給配水手段2としては、浴室床1上全面に水膜を形成させるものであれば特に限定されるものではなく、水膜の形成方法に応じて適宜選択することができる。水膜の形成方法として、例えば、排水口8の時間当たりの排水量を超える量の水を浴室床1上に給配水することが挙げられる。また、排水口8を閉塞するシャッター等の開閉部材を排水口8に設け、この開閉部材で排水口8を閉じ、その状態で浴室床1全面を覆う量の水を給配水することによっても水膜を形成することができる。したがって、前者の方法で水膜を形成するためには、時間あたり大量の水を給配水することが可能な給配水手段2であることが必要である。例えば、後述するが、大容量の水を供給できる液送ポンプを備えた水タンクが接続された配水管を用いて給配水することが例示される。後者の方法で水膜を形成するためには、浴室床1全面を覆う量の水を給配水できればよいため、例えば、浴室に設置されたシャワーやカランで給配水してもよいし、水を溜めた洗面器等を用いて給配水してもよい。後者の方法で水膜を形成した後、開閉部材を開いて排水口8から浴室床1上の水を排水するが、その排水の間、浴室床1全面にわたって水膜の厚みがほぼ均一な状態で排水されるため、より確実に浴室床1上の水を排水することができる利点がある。   Furthermore, the bathroom according to this embodiment has water supply / distribution means 2 for supplying and distributing water toward the bathroom floor 1, and the bathroom floor 1 has a water repellent function on the surface. The water supply / distribution means 2 is not particularly limited as long as it forms a water film on the entire surface of the bathroom floor 1, and can be appropriately selected according to the method of forming the water film. As a method for forming the water film, for example, water on the bathroom floor 1 is supplied and distributed in an amount exceeding the amount of drainage per hour of the drainage port 8. In addition, an opening / closing member such as a shutter for closing the drainage port 8 is provided in the drainage port 8, the drainage port 8 is closed with this opening / closing member, and water is supplied and distributed in such a state as to cover the entire surface of the bathroom floor 1. A film can be formed. Therefore, in order to form a water film by the former method, it is necessary to be the water supply / distribution means 2 capable of supplying and distributing a large amount of water per hour. For example, as will be described later, water supply / distribution is exemplified using a water distribution pipe connected to a water tank provided with a liquid feed pump capable of supplying a large volume of water. In order to form a water film by the latter method, it is only necessary to supply and distribute an amount of water that covers the entire surface of the bathroom floor 1. For example, water may be supplied and distributed by a shower or currant installed in the bathroom. Water supply and distribution may be performed using a stored washbasin or the like. After the water film is formed by the latter method, the opening / closing member is opened and the water on the bathroom floor 1 is drained from the drain port 8, but the thickness of the water film is almost uniform over the entire bathroom floor 1 during the drainage. Therefore, the water on the bathroom floor 1 can be drained more reliably.

いずれの方法においても水膜の厚みは特に制限はなく、水が浴室床上全面に広がって浴室床を覆っていればよい。また浴室床にわたって厚みが均一でなくともよい。   In any of the methods, the thickness of the water film is not particularly limited as long as the water spreads over the bathroom floor and covers the bathroom floor. The thickness may not be uniform across the bathroom floor.

本実施形態に係る給配水手段2は、図1及び図2に示すように、浴室床1を囲む両側壁4a,4b及び出入口壁6の下部の壁内に水を供給する硬質塩化ビニル樹脂製の配管22が配設され、その配管22には複数のノズル21が等間隔に斜め下方向、つまり浴室床1に向けて取り付けられ、ノズル21の先端部211から水が広角に噴射されるようになっている。それぞれのノズル21の先端部211は排水口8方向に向けられており、ノズル21の先端部211から噴射された水は浴室床1表面に沿って排水口8方向に流れる。配管22の高さ、配管22に取り付けられるノズル21の数や各ノズル21間の間隔、さらに配管22へのノズル21の取り付け角度等は、ノズル21の先端部211から噴射された水が浴室床1上全面に行き渡るように適宜に調整、設定される。   As shown in FIGS. 1 and 2, the water supply / distribution means 2 according to the present embodiment is made of a hard polyvinyl chloride resin that supplies water into the lower walls of the side walls 4 a and 4 b surrounding the bathroom floor 1 and the entrance wall 6. A plurality of nozzles 21 are attached to the piping 22 at an equal interval obliquely downward, that is, toward the bathroom floor 1, so that water is jetted from the tip end portion 211 of the nozzle 21 to a wide angle. It has become. The tip 211 of each nozzle 21 is directed in the direction of the drain 8, and the water sprayed from the tip 211 of the nozzle 21 flows in the direction of the drain 8 along the surface of the bathroom floor 1. The height of the pipe 22, the number of nozzles 21 attached to the pipe 22, the interval between the nozzles 21, the attachment angle of the nozzle 21 to the pipe 22, etc. 1 is adjusted and set appropriately so as to spread over the entire surface.

さらに、液送ポンプを備えた水タンク等の水供給部23が配管22に接続されており、液送ポンプを稼動させることによって配管22に水が供給されノズル21の先端部211から噴射される。この水供給部23は排水口の時間当たりの排水量を超える量の水を供給できるものである。また、液送ポンプの稼動は水供給部23に接続された制御部24でおこなわれ、ノズル21の先端部211から噴射された水が浴室床1上全面に行き渡り、浴室床1上全面に水膜が形成されるまで続く。浴室床1上全面に水膜が形成した後、液送ポンプの運転を停止し、水の供給を止める。水の供給を止めると、浴室床1上の水は排水口8からの排水により徐々に減少していく。図2は、ノズル21の先端部211から噴射された水が浴室床1上全面に行き渡り、浴室床1上全面に水膜Bが形成された状態を表している。   Further, a water supply unit 23 such as a water tank provided with a liquid feed pump is connected to the pipe 22, and water is supplied to the pipe 22 by operating the liquid feed pump and injected from the tip end portion 211 of the nozzle 21. . This water supply part 23 can supply the amount of water exceeding the amount of drainage per hour at the drainage port. The operation of the liquid feed pump is performed by the control unit 24 connected to the water supply unit 23, and the water sprayed from the tip 211 of the nozzle 21 spreads over the entire surface of the bathroom floor 1. Continue until a film is formed. After the water film is formed on the entire surface of the bathroom floor 1, the operation of the liquid feed pump is stopped and the supply of water is stopped. When the supply of water is stopped, the water on the bathroom floor 1 gradually decreases due to drainage from the drain outlet 8. FIG. 2 shows a state in which water sprayed from the tip portion 211 of the nozzle 21 has spread over the entire surface of the bathroom floor 1 and a water film B has been formed on the entire surface of the bathroom floor 1.

浴室床1は、上記のとおり、表面に撥水機能を有しているため浴室床1上の水が移動しやすくなっている。よって、浴室床1上全面に覆われた水(水膜)は、排水時、水がつながった状態で引っ張られて排水口8まで容易に到達する、つまり、水が途切れずに連続的に排水されるため、浴室床1上には水残りがほとんどない。これを図3に基づいて説明する。   As described above, since the bathroom floor 1 has a water repellent function on the surface, the water on the bathroom floor 1 is easy to move. Therefore, the water (water film) covered on the entire surface of the bathroom floor 1 is easily pulled up to the drain outlet 8 when drained, that is, the water is continuously drained without interruption. Therefore, there is almost no water remaining on the bathroom floor 1. This will be described with reference to FIG.

図3(a)は、浴室床1上に島状に残水し、水滴Aが残っている状態を表している。この状態の浴室床1上に給配水手段で水を給配水すると、浴室床1上の水滴Aが給配水した水に吸収されると共に図3(b)に示すように、浴室床1上全面に水膜Bが形成される。水膜B形成後、水の給排水を停止すると、浴室床1上の水は図示していないが図外左側に設置してある排水口からの排水により、浴室床1上の水は徐々に減少していく。浴室床1表面は撥水機能を有しているため浴室床1上の水は移動しやすくなっており、排水口から離れた場所の水であっても、表面張力によって水がつながった状態(水膜が形成された状態)で途切れることなく排水口まで移動して連続的に排水口から排水され、最終的には浴室床1上に水がほとんど残らない。図3(c)は、浴室床1上の水膜Bが途切れることなく排水口に向かって左方向に浴室床1上を移動している状態を表している。   FIG. 3A shows a state where water remains in an island shape on the bathroom floor 1 and water droplets A remain. When water is supplied / distributed on the bathroom floor 1 in this state by the water supply / distribution means, the water droplet A on the bathroom floor 1 is absorbed by the supplied / distributed water and, as shown in FIG. A water film B is formed on the surface. When water supply / drainage is stopped after the formation of water film B, water on bathroom floor 1 is not shown, but water on bathroom floor 1 gradually decreases due to drainage from the drain outlet located on the left side of the figure. I will do it. Since the surface of the bathroom floor 1 has a water repellent function, the water on the bathroom floor 1 is easy to move, and even when the water is far from the drain, the water is connected by the surface tension ( In the state where the water film is formed), the water moves to the drain port without interruption and is continuously drained from the drain port. Finally, almost no water remains on the bathroom floor 1. FIG.3 (c) represents the state which the water film B on the bathroom floor 1 is moving on the bathroom floor 1 in the left direction toward a drain outlet, without interrupting.

したがって、本発明の浴室は、浴室使用後、石鹸垢や皮脂、湯垢等の汚染物質を含む水滴が浴室床表面に残っていても、浴室床上全面に水膜を形成するように水を給配水した後、これを排水することにより、浴室床表面に残っていた水滴が給配水した水と共に排水されて石鹸垢や皮脂、湯垢等の汚染物質を効果的に除去することができ、浴室床表面を洗浄することができる。   Therefore, the bathroom of the present invention supplies and distributes water so that a water film is formed on the entire surface of the bathroom floor even if water droplets containing contaminants such as soap stains, sebum, and scale remain on the bathroom floor after use. After draining, the water droplets remaining on the bathroom floor surface are drained together with the water supplied and distributed so that contaminants such as soap stains, sebum, and scale can be effectively removed. Can be washed.

このように本実施形態に係る浴室の浴室床上の水は途切れずに連続的に排水されるものであるが、例えば、図1に示すように、浴室床1は排水口8が最も低くなるような下り傾斜を有していてもよい。これによって、浴室床1上の水がこの傾斜に沿って流れ、排水口8に向かって集水されやすくなってもいる。床勾配としては0.1°以上5°未満であることが好ましい。0.1°未満では傾斜の効果がほとんど得られず、5°を超える場合には排水口8へ向かう水の流速が速くなりすぎて水が途切れてしまい連続的に排水されない場合があったり、浴室使用者が足を滑らせて転倒する等の危険があるため好ましくない。   As described above, the water on the bathroom floor of the bathroom according to the present embodiment is continuously drained without interruption. For example, as shown in FIG. 1, the bathroom floor 1 has the lowest outlet 8. It may have a downward slope. As a result, the water on the bathroom floor 1 flows along this slope, and the water tends to be collected toward the drain port 8. The floor gradient is preferably 0.1 ° or more and less than 5 °. If the angle is less than 0.1 °, the effect of the inclination is hardly obtained. If the angle exceeds 5 °, the flow rate of water toward the drain port 8 becomes too fast, and the water is interrupted and may not be continuously drained. This is not preferable because there is a danger that the user of the bathroom slips and falls.

また、浴室床1表面の撥水機能は、水に対する接触角が70°以上であることが好ましい。これによって、浴室床1上の水が途切れることなく、より一層容易に排水口8まで移動しやすくなる。好適には70°〜90°である。70°未満の場合には、排水時、浴室床1上の水膜が途切れてしまう場合があるため好ましくない。このような撥水機能は、例えば、フッ素系塗料やシリコン系塗料等の撥水性塗料をスプレーコート、リップコート、刷毛塗り等の各種の方法で浴室床1表面に塗布することで実現される。   The water repellent function of the surface of the bathroom floor 1 preferably has a contact angle with water of 70 ° or more. Thereby, the water on the bathroom floor 1 is more easily moved to the drain outlet 8 without interruption. It is preferably 70 ° to 90 °. If it is less than 70 °, the water film on the bathroom floor 1 may be interrupted during drainage, which is not preferable. Such a water-repellent function is realized by applying a water-repellent paint such as a fluorine-based paint or a silicon-based paint to the surface of the bathroom floor 1 by various methods such as spray coating, lip coating, and brush coating.

本発明の浴室の別の実施形態として、図4に示すように、浴室床1表面に、排水口8を中心として放射状に延びる凹溝9を設けてもよい。この凹溝9は、排水時、浴室床1上の水がこの凹溝9を通じて排水口8に向かって連続する流路を形成させるためのものである。これによって、浴室床1上の水がより効果的に排水される。このような凹溝9は、例えば、幅2〜10mm、深さ1〜5mmに設定され、断面視形状はU字形やV字形等でもよく特に制限されない。図4では断面視U字形の凹溝9としている。また凹溝9は浴室床1を囲む両側壁や出入口壁まで延びていてもよいし、図4のようにその近傍又は浴室床の中程まで延びるように設けられていてもよい。浴室床1表面上の凹溝9の数は特に制限されるものではないが、凹溝9の数が多すぎると、浴室床1とその上に形成される水膜との接触面積が大きくなり、これに伴って浴室床1上の水の排水時の抵抗が大きくなり、水が途切れてしまう場合があるので好ましくない。このため、浴室床1の大きさにもよるが、例えば5〜10程度の数の凹溝9を設けるようにすれば十分である。   As another embodiment of the bathroom of the present invention, as shown in FIG. 4, concave grooves 9 extending radially from the drain outlet 8 may be provided on the surface of the bathroom floor 1. The concave groove 9 is for forming a flow path in which water on the bathroom floor 1 continues toward the drain outlet 8 through the concave groove 9 during drainage. Thereby, the water on the bathroom floor 1 is drained more effectively. Such a concave groove 9 is set to have a width of 2 to 10 mm and a depth of 1 to 5 mm, for example, and the sectional view shape may be U-shaped or V-shaped, and is not particularly limited. In FIG. 4, the groove 9 is U-shaped in cross section. Further, the concave groove 9 may extend to both side walls and the entrance / exit wall surrounding the bathroom floor 1, or may be provided so as to extend to the vicinity thereof or the middle of the bathroom floor as shown in FIG. The number of the concave grooves 9 on the surface of the bathroom floor 1 is not particularly limited. However, if the number of the concave grooves 9 is too large, the contact area between the bathroom floor 1 and the water film formed thereon increases. In connection with this, since the resistance at the time of drainage of the water on the bathroom floor 1 becomes large and the water may be interrupted, it is not preferable. For this reason, although it depends on the size of the bathroom floor 1, it is sufficient to provide, for example, about 5 to 10 concave grooves 9.

上記実施形態では、浴室床を囲む両側壁及び出入口壁の下部にノズルを設置し、三方向から水を噴射しているが、特にこれに限定されるものではない。例えば、排水口と対向する側壁の下部にのみ設置して一方向から水を噴射するようにしてもよい。図1の場合では、出入口壁6の下部にのみ設置して水を噴射するようにしてもよい。ノズルの先端部の形状についても、円形状や幅広形状等、各種形状のものを用いることができる。また、上記実施形態ではノズルの先端部から広角に水を噴射しているが、帯状の水膜を生成するスリットノズルを用いて、浴室床面に沿って帯状の水膜を噴射するようにしてもよい。また、上述したように、排水口を閉塞するシャッター等の閉塞部材で排水口を塞いで水を給配水してもよく、この場合には浴室に設置されたシャワーやカラン、水を溜めた洗面器等を用いて給配水する。さらに給配水される水も、上記実施形態では水タンクから給配水しているが、水道管から給配水してもよいし、浴槽の貯水等を使用することもできる。   In the said embodiment, although the nozzle is installed in the lower part of the both-sides wall and the entrance-and-exit wall which enclose a bathroom floor, and water is injected from three directions, it is not specifically limited to this. For example, it may be installed only in the lower part of the side wall facing the drain port and water may be jetted from one direction. In the case of FIG. 1, it may be installed only at the lower part of the entrance / exit wall 6 to inject water. Regarding the shape of the tip of the nozzle, various shapes such as a circular shape and a wide shape can be used. Moreover, in the said embodiment, although water is injected at a wide angle from the front-end | tip part of a nozzle, it is made to inject a strip | belt-shaped water film along a bathroom floor surface using the slit nozzle which produces | generates a strip | belt-shaped water film. Also good. In addition, as described above, the drainage port may be closed with a closing member such as a shutter that closes the drainage port, and water may be supplied and distributed. In this case, a shower or currant installed in the bathroom, or a wash surface in which water is stored Supply and distribute water using a vessel.

In order to form a water film on the entire surface of the bathroom floor, the drain outlet was closed with a shutter, and a large amount of water was distributed to the bathroom floor with a currant. Water distribution was stopped after a water film was formed on the entire surface of the bathroom floor. After opening the shutter and draining water on the bathroom floor from the drain outlet, the appearance of the bathroom floor surface was observed and the amount of water droplets remaining on the bathroom floor was measured.
<Example 2>
1 and 2 was used as a water supply / distribution means, and a water distribution pipe was provided at the lower part of the wall surface (the lower part of the entrance / exit wall 6 in FIG. 1) at a position facing the drain port. In order to form a water film on the entire surface of the bathroom floor, water exceeding the amount of drainage per hour at the drain outlet is supplied and distributed from this pipe to the bathroom floor, and after the water film is formed on the entire surface of the bathroom floor, The appearance of the bathroom floor surface was observed and the amount of water droplets remaining on the bathroom floor was measured in the same manner as in Example 1 except that the operation of the feed pump was stopped and the water supply was stopped to drain the water on the bathroom floor. . The drain outlet of this embodiment is not provided with a shutter for closing the drain outlet as in the first embodiment.
<Example 3>
While observing the appearance of the bathroom floor surface in the same manner as in Example 1 except for the configuration of the bathroom floor shown in FIG. 4 (provided with concave grooves extending radially around the drain outlet on the bathroom floor surface), The amount of water droplets remaining on the bathroom floor was measured.
<Example 4>
While observing the appearance of the bathroom floor surface in the same manner as in Example 2 except for the configuration of the bathroom floor shown in FIG. 4 (provided with a groove extending radially around the drain outlet on the bathroom floor surface), The amount of water droplets remaining on the bathroom floor was measured.
<Comparative Example 1>
The surface of the bathroom floor was observed and the surface remained on the bathroom floor in the same manner as in Example 1 except that the water was not sprayed on the entire surface of the bathroom floor, except that the bathroom floor was sprayed with water. The amount of water droplets was measured.
<Comparative example 2>
The surface of the bathroom floor was observed in the same manner as in Example 2 except that the bathroom floor was sprinkled with a wash basin without forming a water film on the entire surface of the bathroom floor. The amount of remaining water droplets was measured.

表1に結果を示す。   Table 1 shows the results.

Figure 0005198829
Figure 0005198829

表1の結果より、表面に撥水機能を有する浴室床上全面に水膜を形成するように水を給配水することで、排水後の浴室床上の水滴量が減少することが確認できた(実施例1〜4)。これにより、浴室使用後、石鹸垢や皮脂、湯垢等の汚染物質を含む水滴が浴室床表面に残っていても、一旦、浴室床上全面に水膜を形成するように水を給配水してこれを排水することにより、浴室床表面に残っていた水滴が給配水した水と共に排水されて石鹸垢や皮脂、湯垢等の汚染物質が除去されるため、防汚性を向上させることが可能であることがわかる。   From the results of Table 1, it was confirmed that the amount of water droplets on the bathroom floor after draining was reduced by supplying and distributing water so that a water film was formed on the entire surface of the bathroom floor having a water-repellent function on the surface. Examples 1-4). As a result, even after water drops containing contaminants such as soap stains, sebum, and scales remain on the bathroom floor after use in the bathroom, water is once distributed to form a water film on the entire bathroom floor. By draining water, water droplets remaining on the bathroom floor surface are drained with the water supplied and distributed to remove contaminants such as soap stains, sebum, and scales, thus improving the antifouling property. I understand that.

一方で、表面に撥水機能を有する浴室床に給配水していても、浴室床上全面に水膜を形成させることなく散水にとどめた場合には、排水後、浴室床上に多量の水滴が残ることが確認できた(比較例1〜2)。   On the other hand, even if water is supplied to the bathroom floor that has a water-repellent function on the surface, if water is sprayed without forming a water film on the entire surface of the bathroom floor, a large amount of water droplets remain on the bathroom floor after drainage. (Comparative Examples 1-2).
