浴室構造bathroom structure
　本発明は、浴室構造に関する。
　本願は、２０２１年９月２４日に、日本に出願された特願２０２１－１５５１２４号に基づき優先権を主張し、その内容をここに援用する。 The present invention relates to bathroom construction.
This application claims priority based on Japanese Patent Application No. 2021-155124 filed in Japan on September 24, 2021, the contents of which are incorporated herein.
　近年、住宅や各種施設等には、身体障がい者や高齢者等の要介助者を介助するための様々な設備が設置されている。その１つとして、要介助者の身体特性や入浴動作に応じて浴槽の位置を変更可能に構成された浴室が知られている。
　例えば、特許文献１、２では、洗い場床面と、その洗い場床面より一段落とし込まれて設置された浴槽載置床面と、浴槽載置床面を移動し得る可動の浴槽とを有する浴室ユニットが開示されている。 2. Description of the Related Art In recent years, houses, various facilities, and the like have been equipped with various facilities for assisting persons requiring assistance, such as physically handicapped persons and elderly persons. As one of them, there is known a bathroom in which the position of the bathtub can be changed according to the physical characteristics and bathing motion of the person requiring assistance.
For example, Patent Literatures 1 and 2 disclose a bathroom unit having a floor surface of a washing place, a floor surface on which a bathtub is placed, and a movable bathtub that can move on the floor surface on which the bathtub is placed. disclosed.
　特許文献１、２のように、浴槽載置床面が洗い場床面よりも低くされている場合、浴槽載置床面の浴槽が載置されていない部分をそのまま露出させておくと危険である。そのため、浴槽が載置されていない部分には、洗い場床面と高さを揃えるためのサイドボードを設置することが行われている。 As in Patent Documents 1 and 2, when the floor surface on which the bathtub is placed is lower than the floor surface of the washing place, it is dangerous to expose the part of the floor surface on which the bathtub is not placed. Therefore, a sideboard is installed in the part where the bathtub is not placed so that the height is aligned with the floor of the washing area.
　このサイドボードは、浴槽を移動させる際には取り外し、浴槽を移動させた後、新たに浴槽載置床面が露出した部分に設置し直すことが必要である。このサイドボードの取り外しと再設置が浴槽を移動させる度に必要となることが、介助者の負担となっていた。
　さらに、特許文献１の浴室ユニットは、洗い場床面と浴槽載置床面との段差が大きいため、洗い場床面と浴槽の床面との段差が大きく、要介助者が浴槽をまたぐ際に体のバランスを崩しやすい、という問題もあった。 This sideboard must be removed when moving the bathtub, and after the bathtub is moved, it must be re-installed on a newly exposed portion of the floor on which the bathtub is placed. The need to remove and reinstall the sideboard each time the bathtub was moved was a burden on the caregiver.
Furthermore, in the bathroom unit of Patent Document 1, since there is a large step between the floor of the washing place and the floor of the bathtub, there is a large step between the floor of the washing place and the floor of the bathtub. There was also the problem that it was easy to lose balance.
　そこで、特許文献３では、浴槽載置床面の高さを洗い場床面と同等とし、浴槽を浴槽載置床面に直接接した状態で配置する浴室構造が提案されている。
　特許文献３の浴室構造によれば、浴槽を移動させる際にサイドボードの取り外しと再設置を行う必要がなく、かつ、洗い場床面と浴槽の床面との段差が小さいため、要介助者が浴槽をまたぐ際に体のバランスを崩しにくい。 Therefore, Patent Document 3 proposes a bathroom structure in which the height of the floor on which the bathtub is placed is equal to that of the floor of the washing place, and the bathtub is placed in direct contact with the floor on which the bathtub is placed.
According to the bathroom structure of Patent Document 3, there is no need to remove and re-install the sideboard when moving the bathtub, and the step between the floor of the washing area and the floor of the bathtub is small. It is difficult to lose the balance of the body when stepping over the bathtub.
　一方、介助者の負担を減らすため、自動洗浄装置を備える浴槽が提案されている。例えば、特許文献４には浴槽に洗剤をスプレーするノズルを浴槽の上方に取り付けた洗浄装置が開示されている。
　また、特許文献５には、浴槽に洗浄水をスプレーするノズルを浴槽の床中央に取り付けた洗浄装置が開示されている。特許文献５のように浴槽の床中央から洗浄水を四方にスプレーする方式は、浴槽全体を満遍なく洗浄するのに適している。 On the other hand, in order to reduce the burden on caregivers, a bathtub equipped with an automatic cleaning device has been proposed. For example, Patent Literature 4 discloses a washing device in which a nozzle for spraying a detergent into a bathtub is attached above the bathtub.
Further, Patent Document 5 discloses a cleaning device in which a nozzle for spraying cleansing water into the bathtub is attached to the center of the floor of the bathtub. A method of spraying washing water in four directions from the center of the floor of the bathtub as in Patent Document 5 is suitable for washing the entire bathtub evenly.

　特許文献３のように、浴槽載置床面の高さを洗い場床面と同等とした浴槽構造において、特許文献５の浴槽の床中央から洗剤をスプレーする洗浄装置を採用すれば、要介助者の安全性も確保しつつ、介助者の負担のさらなる低減が期待できる。
　しかし、本発明者が検討した結果、特許文献３のように、浴槽を浴槽載置床面に直接接した状態で配置する場合、ノズルの浴槽の下面から突出する部分が浴槽載置床面にぶつかってしまうこと、また、ノズルに洗浄水を供給する配管も設置できないことがわかった。 As in Patent Document 3, in a bathtub structure in which the height of the floor on which the bathtub is placed is the same as that of the floor of the washing area, if the cleaning device of Patent Document 5 that sprays detergent from the center of the floor of the bathtub is adopted, the care-requiring person can It can be expected to further reduce the burden on caregivers while ensuring safety.
However, as a result of examination by the present inventors, when the bathtub is placed in direct contact with the floor on which the bathtub is placed, as in Patent Document 3, the portion of the nozzle protruding from the lower surface of the bathtub collides with the floor on which the bathtub is placed. In addition, it was found that the piping for supplying cleaning water to the nozzles could not be installed.
　本発明は上記事情に鑑み、洗い場の床面と浴槽の床面の高さを同等としやすいため、要介助者の安全性を確保しやすいと共に、浴槽を移動させる際の作業負担が少なく、かつ、浴槽の効率的な自動洗浄も可能な浴槽構造を提供することを課題とする。 In view of the above circumstances, the present invention makes it easy to make the height of the floor of the washing place and the floor of the bathtub equal, so that the safety of the person requiring care can be easily ensured, the work load when moving the bathtub is small, and , to provide a bathtub structure capable of efficient automatic washing of the bathtub.

The protruding portion of the nozzle protruding from and the pipe can be accommodated.
　上述の浴室構造では、浴槽パン床面と洗い場パン床面との間に排水縦溝を形成する。そのため、浴槽パン床面と洗い場パン床面との高さに差を設ける必要がなく要介助者の安全性を確保しやすいと共に、浴槽を移動させる際にサイドボードの取り外しと再設置を行う必要もなく、浴槽を移動させる際の作業負担が少ない。また、ノズルの浴槽下面から突出する部分と配管とを収容可能な空間を、浴槽の移動状況にかかわらず確保できるため、浴槽の効率的な自動洗浄も可能である。 In the bathroom structure described above, a vertical drainage groove is formed between the floor surface of the bathtub pan and the floor surface of the wash area pan. Therefore, there is no need to provide a difference in height between the floor of the bathtub pan and the floor of the washroom pan, making it easy to ensure the safety of the person requiring care. Therefore, there is little work load when moving the bathtub. In addition, since a space that can accommodate the portion of the nozzle that protrudes from the bottom surface of the bathtub and the pipe can be secured regardless of the movement of the bathtub, efficient automatic cleaning of the bathtub is also possible.

It is easy to form a gap that can accommodate the piping. Furthermore, since the floor surface of the bathtub pan is gently inclined, it is easy to ensure the safety of the person requiring assistance.
　本発明の浴室構造における前記浴槽は、前記浴槽の底面内側が、前記排水縦溝と反対側が最も高く、前記排水縦溝側が最も低くなる傾斜で設置されており、前記排水縦溝側の最も低い箇所に排水栓が設けられていることが好ましい。
　上述の浴室構造では、底面内側を大きく傾かせなくとも、底面外側の排水縦溝と反対側の高さをある程度高くできるので、ノズルの浴槽下面から突出する部分と配管とを収容可能な空間を確保しやすい。また、底面内側を大きく傾かせなくとも、浴槽からの排水を速やかに行える。また、底面内側を大きく傾かせる必要がないので、要介助者の安全性を確保しやすい。 The bathtub in the bathroom structure of the present invention is installed at an inclination such that the inside of the bottom surface of the bathtub is highest on the side opposite to the longitudinal drainage groove and lowest on the side of the longitudinal drainage groove, and is lowest on the longitudinal drainage groove side. A drain plug is preferably provided at the location.
In the bathroom structure described above, even if the inside of the bottom surface is not greatly inclined, the height of the side opposite to the vertical drainage groove on the outside of the bottom surface can be increased to some extent, so there is a space that can accommodate the part of the nozzle that protrudes from the bottom surface of the bathtub and the piping. easy to secure. In addition, water can be quickly drained from the bathtub without tilting the inside of the bottom surface. In addition, since it is not necessary to greatly incline the inside of the bottom surface, it is easy to ensure the safety of the person requiring assistance.

　図２は図１のII－II断面図であり、浴槽１０の移動方向Ｍ中央において浴槽の短手方向Ｎに沿って切断した断面図である。 1 and 2 show an example of a bathtub unit 1 according to this embodiment. FIG. 1 is a perspective view of the bathtub unit 1 viewed from the washing place side (the washing place pan floor surface side).
2 is a cross-sectional view taken along the line II-II of FIG. 1, and is a cross-sectional view cut along the lateral direction N of the bathtub 10 at the center of the moving direction M of the bathtub 10. As shown in FIG.
　図１に示すように、浴槽ユニット１は浴槽１０と、浴槽１０の底面（浴槽底面２０）中央に設置されたノズル２と、ノズル２に洗浄液を供給するノズル配管３を備えている。ノズル配管３は中継ボックス４に接続されている。中継ボックス４は洗剤容器５から洗剤が供給される洗剤供給管６が接続されていると共に、水道管７から水が供給されるフレキシブル配管８が接続されている。
　浴槽１０の周面は浴槽エプロン９で覆われている。
　尚、浴槽１０の開口部の短辺（短径）の長辺（長径）に対する比（短辺（短径）／長辺（長径））は、０．２／１．０～０．８／１．０であることが好ましく、０．３／１．０～０．７／１．０であることがより好ましい。 As shown in FIG. 1 , the bathtub unit 1 includes a bathtub 10 , a nozzle 2 installed in the center of the bottom surface of the bathtub 10 (bathtub bottom surface 20 ), and a nozzle pipe 3 for supplying cleaning liquid to the nozzle 2 . Nozzle pipe 3 is connected to relay box 4 . The junction box 4 is connected to a detergent supply pipe 6 to which detergent is supplied from a detergent container 5 and to a flexible pipe 8 to which water is supplied from a water pipe 7 .
The peripheral surface of the bathtub 10 is covered with a bathtub apron 9. - 特許庁
The ratio of the short side (short diameter) to the long side (long diameter) of the opening of the bathtub 10 (short side (short diameter)/long side (long diameter)) is 0.2/1.0 to 0.8/ It is preferably 1.0, more preferably 0.3/1.0 to 0.7/1.0.
　ノズル配管３は浴槽底面２０に固定され、中継ボックス４は浴槽背面２４に固定され、洗剤容器５は、浴槽背面２４と浴槽エプロン９との間に収納されている。これら中継ボックス４、洗剤容器５とノズル配管３及び洗剤供給管６は、浴槽ユニット１の移動に伴い、浴槽１０と一体となって移動するようになっている。 The nozzle pipe 3 is fixed to the bottom surface 20 of the bathtub, the junction box 4 is fixed to the back surface 24 of the bathtub, and the detergent container 5 is stored between the back surface 24 of the bathtub and the apron 9 of the bathtub. The relay box 4, the detergent container 5, the nozzle pipe 3, and the detergent supply pipe 6 move integrally with the bathtub 10 as the bathtub unit 1 moves.
　水道管７は浴室壁面に固定されているので、浴槽ユニット１の移動に伴い水道管７と中継ボックス４との距離が変化する。この距離変化に応じられるよう、フレキシブル配管８の長さは余裕を持った長さとされている。
　ノズル配管３は、浴槽背面２４側から浴槽１０の下を経由してノズル２に接続されている。
　ノズル配管３には、中継ボックス４を経由して洗剤又は水が適宜供給され、ノズル２から、浴槽１０内に向けて洗剤又は水を噴出できるようになっている。 Since the water pipe 7 is fixed to the wall surface of the bathroom, the distance between the water pipe 7 and the junction box 4 changes as the bathtub unit 1 moves. The length of the flexible pipe 8 is made long enough to accommodate this change in distance.
The nozzle pipe 3 is connected to the nozzle 2 via the bottom of the bathtub 10 from the bathtub back surface 24 side.
Detergent or water is appropriately supplied to the nozzle pipe 3 via the relay box 4 so that the detergent or water can be jetted from the nozzle 2 into the bathtub 10 .
　図３に示すように、ノズル２のノズル本体２ａは、浴槽底面２０の外側の面（浴槽底面外側２１）の下側に突出している。すなわち、浴槽１０の下面から突出している突出部分が存在する。ノズル２の吐出口２ｂは、浴槽底面２０の内側の面（浴槽底面内側２２）から、やや上に出ている。ノズル配管３は浴槽背面２４側（浴室壁面側、洗い場パン床面と反対側）から、浴槽底面外側２１に沿わせて配置され、ノズル２に接続されている。 As shown in FIG. 3, the nozzle body 2a of the nozzle 2 protrudes below the outer surface of the bathtub bottom surface 20 (bathtub bottom surface outer side 21). That is, there is a protruding portion that protrudes from the lower surface of the bathtub 10 . The discharge port 2b of the nozzle 2 protrudes slightly upward from the inner surface of the bottom surface 20 of the bathtub (inside 22 of the bottom surface of the bathtub). The nozzle pipe 3 is arranged along the bathtub bottom surface 21 from the bathtub back surface 24 side (bathroom wall surface side, the side opposite to the washing area pan floor surface) and is connected to the nozzle 2 .
　図２に示すように、浴槽底面２０には、浴槽背面２４側から浴槽前面２３に向けて下がる傾斜Ｇが設けられている。

Gradient G preferably has a fractional gradient of 25/1000 to 30/1000. If the fractional slope of the slope G is equal to or higher than the lower limit, the water in the bathtub 10 can be quickly discharged from the bathtub drain plug 14 . Moreover, if the fractional slope of the slope G is equal to or less than the upper limit, the safety of the person requiring assistance is enhanced.
　図１、図２、図４に示すように、浴槽排水栓１４は、浴槽１０の洗い場側の周面（浴槽前面２３）と浴槽底面２０とが交差する位置（浴槽底面２０の排水縦溝５０側の位置）に、移動方向Ｍに沿って横長に設けられている。浴槽底面２０には傾斜Ｇがあるため、この位置は浴槽底面内側２２の最も低い箇所となっている。
　浴槽排水栓１４は、楕円状の排水出口部１５に対して楕円状の栓蓋１６が移動することにより、開閉が行われるようになっている。 As shown in FIGS. 1, 2, and 4, the bathtub drain plug 14 is located at a position where the peripheral surface (bathtub front surface 23) of the bathtub 10 on the washing area side and the bathtub bottom surface 20 intersect (the vertical drainage groove 50 of the bathtub bottom surface 20). side position) and is provided horizontally along the moving direction M. Since the bottom surface 20 of the bathtub has an inclination G, this position is the lowest point inside the bottom surface 22 of the bathtub.
The bathtub drain plug 14 is opened and closed by moving an elliptical plug cover 16 with respect to an elliptical drain outlet portion 15 .
　排水出口部１５の軸方向の高さ方向Ｔに対する角度θは、５５～６５°とすることが好ましい。角度θが好ましい範囲の下限値以上であることにより、排水出口部１５が浴槽底面外側２１から下に突出する長さを小さくすることができる。例えば、角度θを６２．５°とすると、排水出口部１５が浴槽底面外側２１から下に突出する長さを、１０ｍｍに抑えることも可能である。また、要介助者が浴槽前面２３をまたいだ際に、浴槽排水栓１４を踏んでしまうことを避けやすい。
　角度θが好ましい範囲の上限値以下であることにより、浴槽１０からの排水時に残水しにくい。
　浴槽排水栓１４の具体的な構成に限定はないが、例えば、特開２０２０－１８３６４８号公報に記載の排水栓装置の構成を採用することができる。 The angle θ of the axial direction of the drainage outlet portion 15 with respect to the height direction T is preferably 55 to 65°. When the angle θ is equal to or greater than the lower limit of the preferable range, the length by which the drainage outlet 15 protrudes downward from the bathtub bottom surface outer side 21 can be reduced. For example, if the angle θ is 62.5°, it is possible to keep the length of the drainage outlet 15 protruding downward from the outside of the bathtub bottom surface 21 to 10 mm. In addition, when the person requiring assistance straddles the bathtub front surface 23, it is easy to avoid stepping on the bathtub drain plug 14. - 特許庁

　目皿状溝蓋７１は、浴槽排水栓１４からの排水を受け、排水縦溝５０に導くようになっている。目皿状溝蓋７１は、浴槽排水栓１４の排水出口部１５が接触しないよう、上面が凹状に湾曲している。
　排水縦溝５０の底面は、目皿状溝蓋７１と化粧溝蓋７２が置かれている箇所にも、各々排水合流箇所５６の方向に下がる傾斜Ｊが設けられている。 A perforated groove cover 71 is placed on both sides of the drainage confluence point 56 in the drainage groove 50 . In addition, decorative groove lids 72 are placed on both outer sides thereof.
The perforated plate-shaped groove lid 71 receives the drainage from the bathtub drain plug 14 and guides it to the drainage vertical groove 50 . The upper surface of the perforated groove lid 71 is concavely curved so that the drain outlet 15 of the bathtub drain plug 14 does not come into contact with it.
The bottom surface of the drainage longitudinal groove 50 is also provided with an inclination J that descends in the direction of the drainage confluence point 56 at the locations where the perforated groove lid 71 and the decorative groove lid 72 are placed.

　洗い場パン床面４０は、その周縁部から排水縦溝５０へ向けて連側的に低くなるよう構成されている。このような構成により、洗い場パン床面上の水が排水縦溝に流入しやすく、効率的に排水できる。
　より具体的には、洗い場パン床面４０には、排水縦溝５０との境界における移動方向Ｍ両端から、排水用凹部６０との境界に向かう２本の谷線４２が形成されている。

　次に、本実施形態の浴室構造として、上記図５に示した防水パンの上面に、浴槽ユニット１を配置した浴室構造を説明する。
　図６、図７に、本実施形態の浴室構造において、浴槽ユニット１を、防水パンの上の移動方向Ｍの終端（洗い場から見て左側）に配置した状態を示す。なお、図６の浴槽ユニット１については、浴槽１０の配置位置を明確にするため、浴槽エプロン９等を省略し、浴槽１０とノズル２と浴槽排水栓１４のみを示している。
　図６に示すように、浴槽１０は、浴槽パン床面３０と排水縦溝５０の上に置かれた目皿状溝蓋７１の上方に配置され、浴槽１０の移動方向Ｍの中央は、目皿状溝蓋７１の移動方向Ｍのほぼ中央上に位置している。 Next, as a bathroom structure of this embodiment, a bathroom structure in which the bathtub unit 1 is arranged on the upper surface of the waterproof pan shown in FIG. 5 will be described.
6 and 7 show a state in which the bathtub unit 1 is arranged on the end of the waterproof pan in the direction of movement M (on the left side when viewed from the washing area) in the bathroom structure of the present embodiment. 6, only the bathtub 10, the nozzle 2, and the bathtub drain plug 14 are shown without the bathtub apron 9 and the like in order to clarify the arrangement position of the bathtub 10. As shown in FIG.
As shown in FIG. 6, the bathtub 10 is placed above the bathtub pan floor 30 and the perforated groove lid 71 placed on the drainage longitudinal groove 50, and the center of the bathtub 10 in the movement direction M is the eye. It is positioned substantially above the center of the dish-shaped groove cover 71 in the direction of movement M thereof.
　図７は、この状態におけるVII－VII断面における浴槽底面と防水パンとの位置関係を示す浴槽底面２０付近の図である。VII－VII断面は、浴槽１０の移動方向Ｍの中央において短手方向Ｎに沿って切断した断面であり、この断面上に、ノズル２、浴槽排水栓１４が存在する。すなわち、VII－VII断面は、本発明における「浴槽ユニットの移動に伴い前記ノズルが移動する範囲の両終端」の一方の終端における断面である。 FIG. 7 is a view of the vicinity of the bottom surface 20 of the bathtub showing the positional relationship between the bottom surface of the bathtub and the waterproof pan in the VII-VII section in this state. A VII-VII cross section is a cross section cut along the lateral direction N at the center of the movement direction M of the bathtub 10, and the nozzle 2 and the bathtub drain plug 14 are present on this cross section. That is, the VII-VII cross section is a cross section at one end of "both ends of the range in which the nozzle moves with movement of the bathtub unit" in the present invention.
　図７に示すように、本実施形態の防水パンは、浴槽パン１７と洗い場パン１８とが、嵌合部１９において嵌合することにより構成されている。
　浴槽パン１７の上面が浴槽パン床面３０（VII－VII断面においては第１浴槽パン床面３５）と排水縦溝５０の一部を構成し、洗い場パン１８の上面が洗い場パン床面４０と排水縦溝５０の残部を構成している。 As shown in FIG. 7 , the waterproof pan of the present embodiment is constructed by fitting a bathtub pan 17 and a washing pan 18 together at a fitting portion 19 .
The upper surface of the bathtub pan 17 constitutes the bathtub pan floor 30 (the first bathtub pan floor 35 in the VII-VII cross section) and a part of the drainage groove 50, and the upper surface of the washing space pan 18 constitutes the washing space pan floor 40. It constitutes the remainder of the drainage flute 50 .
　浴槽パン１７は、複数の支持脚７０により支持されている。
　VII－VII断面において、第１浴槽パン床面３５は、谷線３２の箇所が高さＨ２とされている。谷線３２の排水縦溝５０側は谷線３２側が低い傾斜Ｂとされ、高さＨ３となった先は、平坦面が多少存在する。谷線３２の浴室壁面７５側は、谷線３２側の方が低い傾斜Ｃとされており、浴室壁面７５側（排水縦溝と反対側）の第１浴槽パン床面３５の高さは、高さＨ１とされている。 Bathtub pan 17 is supported by a plurality of support legs 70 .
In the VII-VII cross section, the first bathtub pan floor surface 35 has a height H2 at the location of the valley line 32 . The valley line 32 on the side of the drainage flute 50 has a low inclination B on the side of the valley line 32, and there is a flat surface at the tip of the height H3. The bathroom wall surface 75 side of the valley line 32 has a lower inclination C on the valley line 32 side. The height is H1.
　高さＨ１、Ｈ２、Ｈ３は以下の関係となっている。
　　Ｈ１＞Ｈ３＞Ｈ２
　高さＨ３が高さＨ２よりも低いため、間に高さＨ３の最下点が存在しても、浴槽パン床面３０上の水は、排水縦溝５０に向かって流れるようになっている。
　以下の説明において、排水縦溝５０との境界における洗い場パン床面４０の高さ（但し、排水用凹部６０が形成されている部分を除く。以下同じ。）を基準面の高さＨ０とする。 The heights H1, H2, and H3 have the following relationship.
H1 > H3 > H2
Since the height H3 is lower than the height H2, the water on the bathtub pan floor surface 30 flows toward the drainage groove 50 even if there is the lowest point of the height H3 in between. .
In the following description, the height of the floor surface of the washing pan 40 at the boundary with the vertical drainage groove 50 (excluding the portion where the drainage recess 60 is formed; the same shall apply hereinafter) shall be the height H0 of the reference surface. .
　本実施形態のVII－VII断面では、高さＨ１が高さＨ０とほぼ等しい例を示したが、高さＨ１の方が高さＨ０よりやや高くすることも好ましい。例えば、高さＨ１の方を高さＨ０より１０ｍｍ高くすることが好ましい。高さＨ１の方を高さＨ０よりやや高くすることにより、谷線３２にかけての勾配が緩やかであっても、高さＨ２を充分に低い位置としやすく、ノズル２やノズル配管３を収容する空隙を形成しやすい。 In the VII-VII section of this embodiment, an example in which the height H1 is substantially equal to the height H0 is shown, but it is also preferable that the height H1 is slightly higher than the height H0. For example, the height H1 is preferably 10 mm higher than the height H0. By making the height H1 slightly higher than the height H0, even if the gradient to the valley line 32 is gentle, the height H2 can be easily set to a sufficiently low position, and the gap for accommodating the nozzle 2 and the nozzle pipe 3 easy to form.
　排水縦溝５０の内、第１排水溝５１とその両側の第１蓋置き場５３（浴槽パン床面３０側）と第２蓋置き場５４（洗い場パン床面４０側）の部分が浴槽パン１７の上面に形成されている。また、第２蓋置き場５４の洗い場パン床面４０側において、中段部５５と第２排水溝５２とが洗い場パン１８の上面に形成されている。浴槽パン１７と洗い場パン１８との嵌合部１９は、第２蓋置き場５４から第２蓋置き場５４と中段部５５との境にかけて形成されている。 In the vertical drainage groove 50, the first drainage groove 51 and the first lid placement area 53 (bathtub pan floor 30 side) and the second lid placement area 54 (washing area pan floor 40 side) on both sides of the drainage groove 50 are the parts of the bathtub pan 17. formed on the top surface. In addition, a middle step portion 55 and a second drainage groove 52 are formed on the upper surface of the washing pan 18 on the washing pan floor surface 40 side of the second lid storage space 54 . A fitting portion 19 between the bathtub pan 17 and the washing space pan 18 is formed from the second lid storage space 54 to the boundary between the second lid storage space 54 and the middle step portion 55 .
　第１排水溝５１は、第２排水溝５２よりも広く深い溝とされている。第１蓋置き場５３と第２蓋置き場５４には、目皿状溝蓋７１の移動方向Ｍ両端側のリブが載せられ、目皿状溝蓋７１を支えるようになっている。目皿状溝蓋７１は、第１排水溝５１と第２排水溝５２の上方を覆っている。
　浴槽排水栓１４から流れ出た排水は目皿状溝蓋７１を通して第２排水溝５２に入り、その後、第１排水溝５１または排水合流箇所５６に流れるようになっている。 The first drainage groove 51 is wider and deeper than the second drainage groove 52 . Ribs on both ends of the perforated groove lid 71 in the moving direction M are placed on the first lid storage place 53 and the second lid storage place 54 to support the perforated groove lid 71 . The perforated groove cover 71 covers the first drainage groove 51 and the second drainage groove 52 from above.
Drainage flowing out of the bathtub drain plug 14 enters the second drain groove 52 through the perforated groove cover 71 and then flows to the first drain groove 51 or the drain confluence point 56 .
　洗い場パン床面４０は第２排水溝５２と隣接している。洗い場パン床面４０の第２排水溝５２と隣接する部分（排水縦溝５０と隣接する部分）は基準面の高さＨ０とされている。高さＨ０と高さＨ１との差が小さいほど、防水パン全体の高さ基準面を同一とすることができるので、施工が容易である。 The washing area pan floor surface 40 is adjacent to the second drainage groove 52 . The portion adjacent to the second drainage groove 52 (the portion adjacent to the vertical drainage groove 50) of the floor surface of the washing pan 40 has a reference plane height H0. The smaller the difference between the height H0 and the height H1, the easier the construction because the height reference plane of the entire waterproof pan can be made the same.
　洗い場パン床面４０の第２排水溝５２と隣接する部分（排水縦溝５０と隣接する部分）である基準面の高さＨ０と高さＨ３との差が小さいほど、浴槽パン床面と洗い場パン床面との境界面での段差が小さいため、要介助者の安全性を確保しやすい。 The smaller the difference between the height H0 and the height H3 of the reference surface, which is the portion adjacent to the second drainage groove 52 (the portion adjacent to the vertical drainage groove 50) of the floor surface of the washing area pan 40, the closer the floor surface of the bathtub pan and the washing area are. Since the step at the interface with the floor of the pan is small, it is easy to ensure the safety of the person requiring assistance.
　浴槽１０の浴槽底面外側２１には、ノズル配管３等に支障がない位置、例えば浴槽底面外側２１の四隅に近い位置に、下方に突出するリブが複数設けられている。
　これらのリブが浴槽パン床面３０、目皿状溝蓋７１、化粧溝蓋７２上に接して浴槽１０を支えることにより、VII－VII断面における浴槽底面外側２１は、浴槽パン床面３０から離間した位置とされている。
　浴槽ユニット１は、移動方向Ｍのいずれかの方向に押されることによって、これらのリブが浴槽パン床面３０等の上を滑り、移動方向Ｍに移動可能となっている。 A plurality of downwardly protruding ribs are provided on the bathtub bottom outside 21 of the bathtub 10 at positions where the nozzle piping 3 and the like are not hindered, for example, at positions near the four corners of the bathtub bottom outside 21 .
These ribs are in contact with the bathtub pan floor 30, the perforated groove lid 71, and the decorative groove lid 72 to support the bathtub 10, so that the bathtub bottom outer side 21 in the VII-VII cross section is separated from the bathtub pan floor 30. position.
The bathtub unit 1 can be moved in the movement direction M by pushing these ribs on the bathtub pan floor surface 30 and the like by being pushed in any direction.
　上述のように、浴槽底面２０には、浴室壁面７５側から浴槽排水栓１４に向けて下がる傾斜Ｇが設けられている。浴槽底面２０は全体として均一な厚みで形成されている。そのため、浴槽底面外側２１と浴槽底面内側２２にも同じ傾斜Ｇが設けられている。
　本実施形態では、浴槽排水栓１４を排水縦溝５０側の最も低い箇所に設け、浴槽底面２０の短手方向Ｎ全体を同じ方向の傾きとした。そのため、短手方向Ｎ中央に排水栓を設けた場合と比較して、浴槽底面外側２１の浴室壁面７５側の高さを高くすることができ、浴槽底面外側２１と浴槽パン床面３０と間に空隙を設けやすい。 As described above, the bathtub bottom surface 20 is provided with an inclination G that descends from the bathroom wall surface 75 toward the bathtub drain plug 14 . The bathtub bottom surface 20 is formed with a uniform thickness as a whole. Therefore, the same slope G is provided on the outside 21 of the bottom surface of the bathtub and the inside 22 of the bottom surface of the bathtub.
In this embodiment, the bathtub drain plug 14 is provided at the lowest point on the side of the drainage groove 50, and the entire lateral direction N of the bathtub bottom surface 20 is inclined in the same direction. Therefore, compared to the case where the drain plug is provided in the center of the lateral direction N, the height of the bathtub bottom outside 21 on the side of the bathroom wall surface 75 can be increased, and the distance between the bathtub bottom outside 21 and the bathtub pan floor 30 can be increased. It is easy to provide a gap in
　VII－VII断面において、ノズル２は、浴槽パン床面３０の谷線３２上に位置している。すなわち、ノズル２の浴槽底面外側２１から突出した部分と、ノズル２に接続されたノズル配管３は、浴槽パン床面３０の最下点（高さＨ３）となる部分に位置するので、浴槽底面外側２１と浴槽パン床面３０と間の空隙に収容され、浴槽パン床面３０に接触しない。 In the VII-VII section, the nozzle 2 is positioned on the valley line 32 of the floor surface 30 of the bathtub pan. That is, since the portion of the nozzle 2 protruding from the outside of the bathtub bottom surface 21 and the nozzle pipe 3 connected to the nozzle 2 are positioned at the lowest point (height H3) of the bathtub pan floor surface 30, It is housed in the gap between the outside 21 and the bathtub pan floor 30 and does not contact the bathtub pan floor 30. - 特許庁
　なお、浴槽ユニット１を、図６の位置から防水パンの上の移動方向Ｍ中央方向に移動させると、ノズル２の通過位置は、谷線３２から徐々に離れていく。しかし領域３５ｂは、移動方向Ｍに沿って同じ高さとされているため、領域３５ｂをノズル２が通過する際、第１浴槽パン床面３５がノズル２やノズル配管３に接触することはない。 It should be noted that when the bathtub unit 1 is moved from the position shown in FIG. However, since the region 35b has the same height along the movement direction M, the first bathtub pan floor surface 35 does not come into contact with the nozzle 2 or the nozzle pipe 3 when the nozzle 2 passes through the region 35b.
　次に、本実施形態の浴室構造において、防水パンの上の移動方向Ｍ中央まで、浴槽ユニット１を移動させた状態を図８、図９に示す。図８においても、浴槽ユニット１については、浴槽１０とノズル２と浴槽排水栓１４のみを示している。
　図８に示すように、浴槽１０は、浴槽パン床面３０と排水縦溝５０の上に置かれた目皿状溝蓋７１の上方に配置され、浴槽１０の移動方向Ｍの中央は、排水縦溝５０の移動方向Ｍ中央の排水合流箇所５６上に位置している。 Next, in the bathroom structure of the present embodiment, FIGS. 8 and 9 show a state in which the bathtub unit 1 is moved to the center of the movement direction M above the waterproof pan. 8 also shows only the bathtub 10, the nozzle 2, and the bathtub drain plug 14 for the bathtub unit 1. As shown in FIG.
As shown in FIG. 8, the bathtub 10 is placed above the bathtub pan floor 30 and the perforated groove lid 71 placed on the drainage longitudinal groove 50, and the center of the bathtub 10 in the movement direction M is the drainage It is located on the drainage confluence point 56 at the center of the vertical groove 50 in the movement direction M.
　図９は、この状態におけるIX－IX断面における浴槽底面と防水パンとの位置関係を示す浴槽底面２０付近の図である。IX－IX断面は、浴槽１０の移動方向Ｍの中央において短手方向Ｎに沿って切断した断面であり、この断面上に、ノズル２、浴槽排水栓１４が存在する。すなわち、IX－IX断面は、本発明における「浴槽ユニットの移動に伴い前記ノズルが移動する範囲の両終端」の中間における断面である。 FIG. 9 is a view of the vicinity of the bottom surface 20 of the bathtub showing the positional relationship between the bottom surface of the bathtub and the waterproof pan in the IX-IX section in this state. The IX-IX cross section is a cross section cut along the lateral direction N at the center of the moving direction M of the bathtub 10, and the nozzle 2 and the bathtub drain plug 14 are present on this cross section. That is, the IX-IX cross section is the cross section at the middle of "both ends of the range in which the nozzle moves with the movement of the bathtub unit" in the present invention.
　浴槽パン１７は、複数の支持脚７０により支持されている。図９の断面において、浴槽パン１７の上面は、浴槽パン床面３０の排水横溝３１と、排水縦溝５０の排水合流箇所５６を構成している。上述のように、IX－IX断面において、排水横溝３１と排水合流箇所５６とは、傾斜Ａで連続している。
　IX－IX断面において、排水横溝３１の浴室壁面７５沿いの高さＨ６は基準面の高さＨ０より大きく下がっている。 Bathtub pan 17 is supported by a plurality of support legs 70 . In the cross section of FIG. 9 , the upper surface of the bathtub pan 17 constitutes the horizontal drainage groove 31 of the bathtub pan floor surface 30 and the drainage confluence point 56 of the vertical drainage groove 50 . As described above, the drainage lateral groove 31 and the drainage junction 56 are continuous at the inclination A in the IX-IX section.
In the IX-IX section, the height H6 of the horizontal drain groove 31 along the bathroom wall surface 75 is much lower than the height H0 of the reference plane.
　高さＨ６と高さＨ０との差により、第１浴槽パン床面３５と第２浴槽パン床面３６とを排水横溝３１よりも高くして、速やかな排水横溝３１への排水を可能としつつ、第１浴槽パン床面３５及び第２浴槽パン床面３６と浴槽底面外側２１との間に、ノズル２とノズル配管３を収容可能な空隙を形成しやすい。 Due to the difference between the height H6 and the height H0, the first bathtub pan floor surface 35 and the second bathtub pan floor surface 36 are made higher than the horizontal drainage groove 31, thereby enabling prompt drainage to the horizontal drainage groove 31. , between the first and second bathtub pan floors 35 and 36 and the bathtub bottom outer side 21, a gap capable of accommodating the nozzle 2 and the nozzle pipe 3 is easily formed.
　洗い場パン１８上面の嵌合部１９に隣接する部分では、排水合流箇所５６と連続する平面を形成している。排水用凹部６０は、この平面より僅かに段落ちして形成されている。　また、短手方向Ｎにおける排水用凹部６０の嵌合部１９と反対側は、洗い場パン床面４０とされている。洗い場パン床面４０は、基準面の高さＨ０とほぼ等しい高さを保ちながら、短手方向Ｎに沿って排水用凹部６０に向かって下がるように傾斜している。 A portion adjacent to the fitting portion 19 on the upper surface of the washing pan 18 forms a flat surface that is continuous with the drain confluence portion 56 . The drainage concave portion 60 is formed so as to be slightly stepped down from this plane. In addition, the side opposite to the fitting portion 19 of the drainage concave portion 60 in the lateral direction N is a washing pan floor surface 40 . The washing space pan floor surface 40 is inclined downward toward the drainage concave portion 60 along the lateral direction N while maintaining a height substantially equal to the height H0 of the reference surface.
　排水用凹部６０には排水口６１が設けられ、排水口６１には、浴室外に排水を導く排水管６２が接続されている。排水管６２は、洗い場パン１８の洗い場パン床面４０の下を通過して、浴室外へと至っている。
　IX－IX断面においては、図９から明らかなように、浴槽底面外側２１と浴槽パン床面３０との間には、ノズル２とノズル配管３を収容する充分な空隙が存在している。 A drainage port 61 is provided in the drainage recess 60, and a drainage pipe 62 is connected to the drainage port 61 for guiding drainage to the outside of the bathroom. The drain pipe 62 passes under the washing pan floor surface 40 of the washing pan 18 and reaches outside the bathroom.
In the IX-IX cross section, as is clear from FIG. 9, there is a sufficient space between the bathtub bottom outside 21 and the bathtub pan floor 30 to accommodate the nozzle 2 and the nozzle pipe 3 .
　浴槽ユニット１をさらに移動させ、防水パンの上の移動方向Ｍの終端（洗い場から見て右側）に配置した状態において、浴槽１０の移動方向Ｍの中央において短手方向Ｎに沿って切断した断面は、図７に示したVII－VII断面と同様となる。この断面が、本発明における「浴槽ユニットの移動に伴い前記ノズルが移動する範囲の両終端」の他方の終端における断面である。 A cross section cut along the lateral direction N at the center of the moving direction M of the bathtub 10 in a state in which the bathtub unit 1 is further moved and arranged at the end of the moving direction M above the waterproof pan (on the right side when viewed from the washing area). is the same as the VII-VII section shown in FIG. This cross section is the cross section at the other end of "both ends of the range in which the nozzle moves with movement of the bathtub unit" in the present invention.
　図７を用いて説明したのと同様に、この断面においても、ノズル２は、浴槽パン床面３０の谷線３２上に位置している。すなわち、ノズル２の浴槽底面外側２１から突出した部分と、ノズル２に接続されたノズル配管３は、浴槽パン床面３０の最下点（高さＨ３）となる部分に位置するので、浴槽底面外側２１と浴槽パン床面３０と間の空隙に収容され、浴槽パン床面３０に接触しない。 The nozzle 2 is positioned on the trough line 32 of the bathtub pan floor surface 30 in this cross section as well as described using FIG. That is, since the portion of the nozzle 2 protruding from the outside of the bathtub bottom surface 21 and the nozzle pipe 3 connected to the nozzle 2 are positioned at the lowest point (height H3) of the bathtub pan floor surface 30, It is housed in the gap between the outside 21 and the bathtub pan floor 30 and does not contact the bathtub pan floor 30. - 特許庁
　また、浴槽ユニット１を、図８の位置から、この他方の終端まで防水パンの上の移動方向Ｍに沿って移動させる過程で、ノズル２の通過位置は、谷線３２から離れている。しかし領域３６ｂは、移動方向Ｍに沿って同じ高さとされているため、領域３６ｂをノズル２が通過して谷線３２上に達するまでの間に、第２浴槽パン床面３６がノズル２やノズル配管３に接触することはない。 Also, in the process of moving the bathtub unit 1 from the position shown in FIG. However, since the area 36b has the same height along the moving direction M, the second bathtub pan floor 36 is not in contact with the nozzle 2 or the bottom surface 36 until the nozzle 2 passes through the area 36b and reaches the valley line 32. There is no contact with the nozzle pipe 3.
　以上説明したように、本実施形態の浴槽ユニット１によれば、洗い場パン床面４０と浴槽底面内側２２の高さを同等としやすいため、要介助者の安全性を確保しやすいと共に、浴槽ユニット１（浴槽１０を含む）を移動させる際の作業負担が少なく、かつ、浴槽１０の効率的な自動洗浄も可能である。 As described above, according to the bathtub unit 1 of the present embodiment, the floor surface 40 of the washing area and the inner surface 22 of the bathtub bottom can be easily made equal in height. 1 (including the bathtub 10) is less burdensome, and efficient automatic cleaning of the bathtub 10 is also possible.
　上記実施形態では、浴槽パン床面３０の具体的な構造を種々特定して説明したが、浴槽１０との間に、ノズル２の浴槽底面外側２１から下方に突出する部分とノズル配管３とを収容可能な空隙を作れる構造であれば、特に限定はない。
　例えば、上記実施形態において、領域３５ｂと領域３６ｂの高さは、移動方向Ｍにおいて一定しているものとしたが、排水横溝３１に向かって低くなる傾斜を設けてもよい。また、上記実施形態において、第１浴槽パン床面３５、第２浴槽パン床面３６を各々平面状の領域３５ａと領域３５ｂ、領域３６ａと領域３６ｂを有するものとしたが、一部又は全部を曲面とてもよい。したがって、各々明確な谷線３２は存在しなくてもよい。 In the above embodiment, various specific structures of the bathtub pan floor surface 30 have been specified and explained. There is no particular limitation as long as it has a structure capable of creating a space that can accommodate the space.
For example, in the above embodiment, the heights of the regions 35b and 36b are constant in the moving direction M, but they may be inclined downward toward the lateral drainage groove 31. FIG. In the above-described embodiment, the first bathtub pan floor surface 35 and the second bathtub pan floor surface 36 each have planar regions 35a and 35b, and regions 36a and 36b. Curved surface is very good. Therefore, each distinct valley line 32 may not exist.
　また、浴槽底面２０には、浴槽パン床面３０上の移動を容易とするため、浴槽底面外側２１の下方に突出するリブと共に、または当該リブに代えて、車輪等を設けてもよい。また、上記実施形態では、ノズル２を浴槽底面２０の中央に配置する構成としたが、ノズル２の位置は、浴槽底面２０の底面にあればよく、中央からずれていてもよい。
　その他、本発明の趣旨を逸脱しない範囲で、種々変更が可能である。 Further, in order to facilitate movement on the bathtub pan floor surface 30, the bathtub bottom surface 20 may be provided with wheels or the like along with ribs projecting downward from the bathtub bottom surface outer side 21 or in place of the ribs. Further, in the above-described embodiment, the nozzle 2 is arranged in the center of the bottom surface 20 of the bathtub, but the position of the nozzle 2 may be located on the bottom surface of the bottom surface 20 of the bathtub and may be shifted from the center.
