Description

本発明は、健常者のみならず高齢者や障害者等にとっても入浴が容易な浴槽及び浴室に関する。   The present invention relates to a bathtub and a bathroom that are easy to bathe not only for healthy people but also for elderly people and disabled people.

ユニットバス等においては、直方体状の浴室空間を効率的に使うため、浴室の出入口側に洗い場を確保し、奥側の浴室壁に寄せて浴槽を配置することが一般的である（特許文献１（図５）参照）。こうした浴槽の底面は洗い場の床面と高さがあまり変わらない一方（特許文献２（図３）参照）、浴槽は身体が浸かる量の湯を容れるために浴槽壁の高さが一定程度あるので、入浴者が浴槽に入ったり浴槽から出たりするには、その一定程度の高さを有する浴槽壁を跨がなければならない。こうした動作は、健常者は無理なく行うことができても、健常者ほど身体の自由がきかない高齢者や障害者等にとっては負担になることがあり、この負担を緩和するために入槽側（洗い場側）の浴槽壁の高さを低めにすることが考えられる。   In a unit bath or the like, in order to efficiently use a rectangular parallelepiped bathroom space, it is common to secure a washing place on the entrance / exit side of the bathroom and arrange a bathtub close to the bathroom wall on the back side (Patent Document 1). (See FIG. 5)). While the bottom of such a bathtub does not change much in height with the floor of the washing area (see Patent Document 2 (FIG. 3)), the bathtub wall has a certain height to accommodate the amount of hot water that can be immersed in the body. In order for the bather to enter or leave the bathtub, the bather must straddle the bathtub wall having a certain height. Even if a healthy person can do this without difficulty, it can be a burden for the elderly and disabled people who are not as free as the healthy person. To ease this burden, It may be possible to lower the height of the bathtub wall on the washing area side.

しかしながら、入槽側の浴槽壁の高さを全体的に低くすると、入浴者がこれを立ち姿勢で跨ぐのであれば跨ぐべき高さは確かに低くなるが、入浴者が浴槽の出入りを浴槽壁に腰掛けた状態で行おうとする場合には、浴槽壁の高さを低くしない場合と同様に臀部の位置以上の高さまで脚を上げて浴槽壁を越えなければならず、負担の軽減に直結しないという問題がある。   However, if the height of the bath wall on the bath side is lowered as a whole, if the bather straddles it in a standing position, the height that should be straddled will certainly be lower, but the bather will not enter and exit the bath wall. If you are going to sit on the floor, you must go over the bathtub wall by raising your legs to the height of the buttock as if you did not reduce the height of the bathtub wall, which does not directly reduce the burden There is a problem.

また、ユニットバスでは入槽側の浴槽壁の近くの浴室壁にシャワーや水栓（蛇口）等の吐水設備が設けられることが多く（特許文献３（図２）参照）、その浴槽壁近くでは身体等に当たった水の跳ね返りが生じやすいので、浴槽壁の高さを全体的に低くすると、身体等を洗い流す水（いわば使用済みの水）が跳ねて浴槽に入る可能性が高くなり、浴槽内の湯を清潔に保つという観点からは好ましくない。   Moreover, in the unit bath, water discharge facilities such as a shower and a faucet (faucet) are often provided on the bathroom wall near the bathtub wall on the tank side (see Patent Document 3 (FIG. 2)). Since the water that hits the body is likely to bounce, if the overall height of the bathtub wall is lowered, there is a higher possibility that the water that washes the body (used water) jumps and enters the bathtub. It is not preferable from the viewpoint of keeping the inner hot water clean.

そこで、入槽側の浴槽壁の高さを全体的にではなく部分的に低くすることも考えられるが、浴槽壁全周のうち入槽側だけを部分的に低くすると、浴槽内から湯が溢れるときにはそこから勢いよく一気に溢れ出て、浴槽に出入りする入浴者の足下に湯（又は水）が溜まりやすくなるという不都合がある。   Therefore, it is conceivable to lower the height of the bath wall on the tub side rather than entirely, but if only the tub side is partially lowered on the entire circumference of the bath wall, When it overflows, there is an inconvenience that hot water (or water) easily overflows from there and easily accumulates in the feet of bathers entering and leaving the bathtub.

さらに、浴槽壁の高さを部分的に低くした場合、浴槽壁の上に載置される浴槽蓋と、浴槽壁の低くした部分との間に隙間が生じ、密閉性が悪くなるおそれがある。このような隙間があると浴槽からの放熱が大きく、湯を沸かすための所要時間が長くなり、また保温性も低下してしまう。また浴室内の結露も増加し、浴室全体が冷えやすいという問題がある。
特開２００６−１８０９５６号公報 特開２００５−２８７５３０号公報 特開２００１−１２３６８３号公報 Furthermore, when the height of the bathtub wall is partially lowered, a gap may be generated between the bathtub lid placed on the bathtub wall and the lowered portion of the bathtub wall, which may deteriorate the sealing performance. . If there is such a gap, the heat release from the bathtub is large, the time required for boiling the hot water becomes long, and the heat retention is also lowered. There is also a problem that condensation in the bathroom increases, and the entire bathroom is easy to cool.
Japanese Patent Laid-Open No. 2006-180956 JP 2005-287530 A JP 2001-123683 A

本発明は、上記の事情に鑑みてなされたもので、高齢者や障害者等にとっても入浴が容易であり、また浴槽蓋の密閉性も良好な浴槽及び浴室を提供することを課題としている。   The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bathtub and a bathroom that are easy to bathe for the elderly and disabled, and that have a good sealing property of the bathtub lid.

上記課題を解決するために、本発明に係る浴槽は、入槽側の浴槽壁と、この浴槽壁に対向する浴槽壁との両方の上面の中央部に、凹部が形成されていることを特徴とする。   In order to solve the above-described problems, the bathtub according to the present invention is characterized in that a recess is formed in the center part of the upper surface of both the bathtub wall on the tank side and the bathtub wall facing the bathtub wall. And

この浴槽では、入槽側浴槽壁の上面中央部に他の部分よりも低い凹部が形成されているので、入浴者が浴槽に立ち姿勢で出入りする場合には、この凹部の部分を跨げば楽に出入りすることができる。このとき、浴槽壁上面の凹部の両側は凹部より高く、入浴者の手が届きやすくなっているので、入浴者はその部分を掴んで浴槽壁を跨ぐことにより安定した姿勢で浴槽に出入りすることができる。   In this bathtub, since a recessed portion lower than the other portions is formed in the central portion of the upper surface of the tub side bathtub wall, when the bather enters and exits the bathtub in a standing posture, the recessed portion should be straddled. You can go in and out easily. At this time, both sides of the recess on the upper surface of the bathtub wall are higher than the recess, making it easier for the bather to reach, so that the bather can enter and exit the bathtub in a stable posture by grasping that part and straddling the bathtub wall Can do.

一方、入浴者が浴槽に出入りする際に一旦入槽側浴槽壁の上面に腰掛け、座位で左右の脚を順番に上げて脚が一つずつ浴槽壁を越えるような動作をする場合には、入浴者が浴槽壁上面の凹部でない箇所に凹部の方を向いて腰掛け、脚が凹部の上を通過して浴槽壁を越えるようにすることによって、脚を臀部の位置以上に高く上げるという負担のかかる動作をせずに浴槽に出入りすることができる。   On the other hand, when the bather enters and exits the bathtub, he sits on the upper surface of the bath tub side wall and raises the left and right legs in order and moves the legs one by one over the bathtub wall. The burden is that the bather raises the leg higher than the position of the buttock by sitting on the recessed portion on the upper surface of the bathtub wall facing the recessed portion and allowing the leg to pass over the recessed portion and over the bathtub wall. It is possible to enter and leave the bathtub without such an operation.

上記入槽側浴槽壁の上面は、中央部（凹部）以外は低くなっていないので、この浴槽壁近くの浴室壁にシャワーや水栓等の吐水設備が設けられてその付近で身体を洗い流す水等が跳ねたとしても浴槽壁に遮られ、それが浴槽内にまで飛散する可能性は抑制される。   Since the upper surface of the tub-side bathtub wall is not lowered except for the central part (concave part), water is washed away in the vicinity of the bathroom wall provided with water discharge equipment such as a shower and a faucet. Even if it bounces, etc., it is blocked by the bathtub wall, and the possibility that it will scatter into the bathtub is suppressed.

さらに、入槽側浴槽壁に対向する浴槽壁の上面中央部にも凹部が形成されているので、入浴者の出入り等に伴い浴槽内から湯が溢れ出そうになっても、湯は入槽側浴槽壁の凹部にのみ向かって集中的に流れるのではなく、それに対向する浴槽壁の凹部にも向かい湯の流れが拡散し、このため、湯が入槽側浴槽壁の凹部から一気に溢れ出てその下の洗い場床面に溜まりやすくなるという事態を抑制することができる。   In addition, since a recess is formed in the center of the upper surface of the bathtub wall facing the bathtub wall on the tub side, even if hot water is about to overflow from the bathtub as the bather enters and leaves, the hot water will enter the tank. The hot water does not flow intensively toward only the concave portion of the side bathtub wall, but the hot water flow also diffuses into the concave portion of the bathtub wall facing it, so that the hot water overflows from the concave portion of the tub side bathtub wall. Therefore, it is possible to suppress the situation where it easily collects on the floor of the wash floor underneath.

つまり、この浴槽は、浴槽壁の高い浴槽や単に入槽側浴槽壁を全体的又は部分的に低くした浴槽に比べ、浴槽内の湯の汚れやすさや洗い場床面における湯（又は水）の溜まりやすさの点でデメリットを負うことなく出入りのしやすさが改善されており、健常者のみならず高齢者や障害者等にとっても入浴を容易なものとしている。   In other words, this bathtub has a higher tub wall and a tub that has a lower or lower overall basin wall, or the pool of hot water (or water) on the floor of the washroom. The ease of going in and out has been improved without incurring any demerits in terms of ease, making bathing easy not only for healthy people but also for elderly and disabled people.

また、入槽側および対向する壁側の両方の浴槽壁の中央部を低くしたことにより、浴槽壁全体としてみたとき、長手方向には高低の変動が生じているが、短手方向には同じ高さとなっている。従って、平面を屈曲させた形状の浴槽蓋によって、高い密閉性をもって蓋をすることができる。   In addition, by lowering the central part of the bathtub wall on both the tank side and the opposite wall side, when viewed as the entire bathtub wall, there are fluctuations in height in the longitudinal direction, but the same in the short direction. It is height. Therefore, it is possible to cover the bath lid with a high hermeticity by the bathtub lid having a curved shape.

なお、入槽側浴槽壁の上面における凹部以外の箇所には幅広部が形成されていることが好ましく、入浴者は、浴槽に座位で出入りする場合にその幅広部に腰掛けることによって、より安定した姿勢で出入りを行うことができる。   In addition, it is preferable that a wide portion is formed in a portion other than the concave portion on the upper surface of the bath tub side bathtub wall, and the bather is more stable by sitting on the wide portion when entering and exiting the bathtub in a sitting position. You can go in and out with posture.

また、本発明に係る浴室は、入槽側の浴槽壁及びこの浴槽壁に対向する浴槽壁の各上面の中央部に凹部が形成されるとともに、入槽側浴槽壁の上面における凹部以外の箇所に幅広部が形成された浴槽を備え、その入槽側浴槽壁の凹部に対して幅広部と反対側に位置する浴室壁に、手摺りが設けられていることを特徴とする。   In addition, the bathroom according to the present invention has a recessed portion formed in the central portion of each upper surface of the bathtub wall on the tub side and the bathtub wall facing the tub wall, and a portion other than the recessed portion on the upper surface of the tub side bathtub wall. The bathtub is provided with a wide portion, and a handrail is provided on a bathroom wall located on the opposite side of the wide portion with respect to the concave portion of the bath-side bathtub wall.

この浴室では、浴槽について上記同様の効果が得られるとともに、入槽側浴槽壁の凹部に対して幅広部と反対側に位置する浴室壁に手摺りが設けられているので、その反対側の上面幅を幅広部よりも狭くしておけば、あるいは、反対側の方に凹部を延在させれば（こうした上面幅の狭小化や凹部の延在化を幅広部の方について行うことは幅広部との関係で設計上困難を来すが、幅広部の反対側の方についてであれば容易に実現することができる。）、入浴者が立ち姿勢で入槽側浴槽壁を跨ぎやすくなるだけでなく手摺りを掴むことも可能となり、立ち姿勢での入浴が一層容易となる。   In this bathroom, the same effect as described above can be obtained with respect to the bathtub, and a handrail is provided on the bathroom wall located on the opposite side to the wide portion with respect to the concave portion of the tub-side bathtub wall. If the width is made narrower than the wide part, or if the concave part is extended toward the opposite side (the narrowing of the upper surface width or the extension of the concave part is performed on the wide part) However, it can be easily realized if it is on the opposite side of the wide part.), The bather can easily cross the bath tub side wall in a standing position. It is also possible to grab a handrail without taking a bath, making it easier to bathe in a standing position.

本発明によれば、健常者のみならず高齢者や障害者等にとっても浴槽の出入りが容易であり、また浴槽蓋の密閉性も良好な浴槽及び浴室を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the entrance and exit of a bathtub is easy for not only a healthy person but an elderly person, a disabled person, etc., and the bathtub and bathroom which the sealing property of a bathtub lid is favorable can be provided.

本発明を実施するための最良の形態について、図面を用いて説明する。   The best mode for carrying out the present invention will be described with reference to the drawings.

図１に示すように、本発明に係る浴室１は、ユニットバスとして浴室壁２，３，４，５で周囲を区画された直方体状の浴室空間６を有する。ユニットバスが１６２５サイズであれば、浴室壁２，４の内寸幅は２５００ｍｍ、浴室壁３，５の内寸幅は１６００ｍｍであり、浴室壁５には脱衣所と通じるドア（図示略）が設けられている。浴室空間６には、そのドアの側に洗い場７が設けられ、ドアからみて奥側にある浴室壁３に寄せて浴槽８が設けられている。   As shown in FIG. 1, a bathroom 1 according to the present invention has a rectangular parallelepiped bathroom space 6 that is partitioned by bathroom walls 2, 3, 4, and 5 as a unit bath. If the unit bath is 1625 size, the inner dimension width of the bathroom walls 2 and 4 is 2500 mm, the inner dimension width of the bathroom walls 3 and 5 is 1600 mm, and the bathroom wall 5 has a door (not shown) leading to the dressing room. Is provided. In the bathroom space 6, a washing place 7 is provided on the door side, and a bathtub 8 is provided near the bathroom wall 3 on the back side when viewed from the door.

洗い場７には、シャワー９と、水栓１０と、カウンターテーブル１１と、鏡１２とが浴室壁２に取り付けられて設けられている。浴室壁２にはブラケットタイプのライト１３，１３が設けられるとともに、浴室奥までの略全幅に亘って手摺り１４が設けられている。浴室壁３には手摺り１５が設けられ、手摺り１４，１５は浴室壁２，３の交わる隅で連続し、手摺りを伝う入浴者を洗い場７から浴槽８まで（あるいは、浴槽８から洗い場７まで）案内する。洗い場７の床面１６には、排水部１７が設けられている。   In the washing place 7, a shower 9, a faucet 10, a counter table 11, and a mirror 12 are attached to the bathroom wall 2. The bathroom wall 2 is provided with bracket-type lights 13 and 13, and a handrail 14 is provided over substantially the entire width to the back of the bathroom. A handrail 15 is provided on the bathroom wall 3, and the handrails 14 and 15 are continuous at the corners where the bathroom walls 2 and 3 meet, so that a bather traveling along the handrail can be washed from the washing place 7 to the bathtub 8 (or from the bathtub 8 to the washing place). 7) Guide. A drainage 17 is provided on the floor 16 of the washing place 7.

浴槽８は、入槽側（洗い場７側）の浴槽壁１８と、これに対向する浴室壁３側の浴槽壁１９と、浴槽壁１８，１９とともに浴槽空間２０を形成する浴槽壁２１，２２とを有する。浴槽壁１９は浴室壁３に接し、浴槽壁２１は浴室壁２に接し、浴槽壁２２は浴室壁４に接しており、各浴槽壁の上面と各浴室壁との間の隙間はシールされている。   The bathtub 8 includes a bathtub wall 18 on the tub side (washing station 7 side), a bathtub wall 19 on the bathroom wall 3 side opposite to the bathtub wall 21 and 22 that form a bathtub space 20 together with the bathtub walls 18 and 19. Have The bathtub wall 19 is in contact with the bathroom wall 3, the bathtub wall 21 is in contact with the bathroom wall 2, the bathtub wall 22 is in contact with the bathroom wall 4, and the gap between the upper surface of each bathtub wall and each bathroom wall is sealed. Yes.

浴槽壁１８の上面２３の長手方向中央部には、凹部２４が形成されている。図２及び図３に示すように、上面２３において、凹部２４の浴室壁２側には、浴槽壁２１の上面２５に連なる上段部２６が形成されている。凹部２４の浴室壁４側には、浴槽壁２２の上面２７に連なるとともに、平面視で凹部２４や上段部２６よりも幅広となっている幅広部２８が形成されている。凹部２４は、略水平で上面２３の最低位置となる下段部２９と、下段部２９及び上段部２６を滑らかに連続する傾斜面部３０と、下段部２９及び幅広部２８を滑らかに連続する傾斜面部３１とを備える。ここでは、下段部２９は浴槽８の全長に対して３分の１程度（凹部２４全体では浴室８の全長に対して３分の２程度）の長さを有し、上段部２６及び幅広部２８よりも６０ｍｍ〜９０ｍｍ程度低い位置にある。   A recess 24 is formed in the central portion in the longitudinal direction of the upper surface 23 of the bathtub wall 18. As shown in FIGS. 2 and 3, on the upper surface 23, an upper step portion 26 that is continuous with the upper surface 25 of the bathtub wall 21 is formed on the recessed wall 24 on the side of the bathroom wall 2. On the side of the bathroom wall 4 of the recess 24, a wide portion 28 is formed which is continuous with the upper surface 27 of the bathtub wall 22 and is wider than the recess 24 and the upper step portion 26 in plan view. The concave portion 24 includes a lower step portion 29 that is substantially horizontal and is the lowest position of the upper surface 23, an inclined surface portion 30 that smoothly continues the lower step portion 29 and the upper step portion 26, and an inclined surface portion that smoothly continues the lower step portion 29 and the wide portion 28. 31. Here, the lower step portion 29 has a length of about one third with respect to the entire length of the bathtub 8 (the entire recess portion 24 has a length of about two thirds with respect to the total length of the bathroom 8), and the upper step portion 26 and the wide portion. It is in a position lower by about 60 mm to 90 mm than 28.

同様に、浴槽壁１９の上面３２の長手方向中央部には、凹部３３が形成されている。上面３２において、凹部３３の浴室壁２側には、浴槽壁２１の上面２５に連なる上段部３４が形成されている。凹部３３の浴室壁４側には、浴槽壁２２の上面２７に連なる上段部３５が形成されている。凹部３３は、略水平で上面３２の最低位置となる下段部３６と、下段部３６及び上段部３４を滑らかに連続する傾斜面部３７と、下段部３６及び上段部３５を滑らかに連続する傾斜面部３８とを備える。凹部３３は凹部２４と正面視で同一形状を呈し、下段部３６の高さは下段部２９の高さと同一となっている。   Similarly, a recess 33 is formed in the longitudinal center of the upper surface 32 of the bathtub wall 19. On the upper surface 32, an upper step portion 34 that is continuous with the upper surface 25 of the bathtub wall 21 is formed on the bathroom wall 2 side of the recess 33. On the bathroom wall 4 side of the recess 33, an upper step portion 35 that is continuous with the upper surface 27 of the bathtub wall 22 is formed. The concave portion 33 includes a lower step portion 36 that is substantially horizontal and at the lowest position of the upper surface 32, an inclined surface portion 37 that smoothly continues the lower step portion 36 and the upper step portion 34, and an inclined surface portion that smoothly continues the lower step portion 36 and the upper step portion 35. 38. The concave portion 33 has the same shape as the concave portion 24 when viewed from the front, and the height of the lower step portion 36 is the same as the height of the lower step portion 29.

この浴槽８では、入槽側の浴槽壁１８の上面２３の中央部に凹部２４が形成されているので、入浴者が浴槽に立ち姿勢で出入りする場合には、この凹部２４の部分を跨げば楽に出入りすることができる。本実施形態では、特に、凹部２４に対して幅広部２８と反対側に位置する浴室壁２に手摺り１４が設けられ、その反対側の方（浴室壁２の方）に凹部２４が延在しているので（図１参照）、入浴者が立ち姿勢で浴槽壁１８を跨ぎやすくなっているだけでなく手摺り１４を掴むことも可能となっており、立ち姿勢での入浴が容易である。手摺り１４を必要としない場合には、入浴者は上段部２６や傾斜面部３０，３１等を掴んで凹部２４を跨ぐことにより、安定した立ち姿勢で浴槽８に出入りすることができる。   In this bathtub 8, since the recessed part 24 is formed in the center part of the upper surface 23 of the bathtub wall 18 by the side of a tub, when a bather enters / exits in a bathtub with standing posture, it straddles the part of this recessed part 24 You can go in and out easily. In this embodiment, in particular, the handrail 14 is provided on the bathroom wall 2 located on the opposite side to the wide portion 28 with respect to the recess 24, and the recess 24 extends on the opposite side (the bathroom wall 2). (See FIG. 1), the bather can easily cross the bathtub wall 18 in a standing posture, and can also grab the handrail 14 and can easily take a bath in the standing posture. . When the handrail 14 is not required, the bather can get in and out of the bathtub 8 in a stable standing posture by grasping the upper step portion 26 and the inclined surface portions 30 and 31 and straddling the concave portion 24.

一方、入浴者が一旦浴槽壁１８の上面２３に腰掛け、座位で左右の脚を順番に上げて脚が一つずつ浴槽壁１８を越えるようにして浴槽８に出入りしようとする場合には、図４に示すように、入浴者Ｂが浴槽壁１８の幅広部２８に凹部２４の方を向いて腰掛け、脚Ｌが凹部２４の上を通過して浴槽壁１８を越えるようにすることによって、脚Ｌを臀部Ｈの位置以上に高く上げるという負担のかかる動作をせずに浴槽８に出入りすることができる。幅広部２８は上面２３において例えば下段部２９よりも１６０ｍｍ〜２００ｍｍ程度幅が広く、これにより入浴者は安定した座り姿勢で浴槽８に出入りすることが可能となっている。   On the other hand, when the bather once sits on the upper surface 23 of the bathtub wall 18 and raises the left and right legs in a sitting position in order to go into and out of the bathtub 8 so that the legs cross the bathtub wall 18 one by one, 4, the bather B sits on the wide portion 28 of the bathtub wall 18 facing the concave portion 24, and the leg L passes over the concave portion 24 and crosses the bathtub wall 18. It is possible to enter and exit the bathtub 8 without performing a burdensome operation of raising L higher than the position of the buttock H. The wide portion 28 is wider on the upper surface 23 by, for example, about 160 mm to 200 mm than the lower step portion 29, so that the bather can enter and leave the bathtub 8 in a stable sitting posture.

また、浴槽壁１８は凹部２４以外の箇所は低くなっていないので、浴槽壁１８の近くで身体を洗い流す水等が跳ねたとしても浴槽壁１８（とりわけ上段部２６，２８に対応する高い部分）に遮られ、それが浴槽８内にまで飛散する可能性は抑制される。   Moreover, since the part other than the recessed part 24 is not low in the bathtub wall 18, even if the water which wash | cleans a body near the bathtub wall 18 splashes, the bathtub wall 18 (especially high part corresponding to the upper steps 26 and 28) The possibility that it is blocked by the air and scattered into the bathtub 8 is suppressed.

さらに、浴槽壁１８に対向する浴槽壁１９の上面３２の中央部にも凹部３３が形成されているので、入浴者の出入り等に伴い浴槽８内から湯が溢れ出そうになっても、湯は浴槽壁１８の凹部２４にのみ向かって集中的に流れるのではなく、浴槽壁１９の凹部３３に向かっても流れる。すなわち、湯の流れが洗い場７に向かう方向及び浴室壁３に向かう方向に拡散するので、湯が浴槽壁１８の凹部２４から一気に溢れ出てその下の床面１６に溜まりやすくなるという事態を抑制することができる。   Furthermore, since the recessed part 33 is formed also in the center part of the upper surface 32 of the bathtub wall 19 which opposes the bathtub wall 18, even if a hot water seems to overflow from the bathtub 8 with a bather's entering / exiting etc., Flows not only intensively toward the recess 24 of the bathtub wall 18 but also toward the recess 33 of the bathtub wall 19. That is, since the flow of hot water diffuses in the direction toward the washing place 7 and in the direction toward the bathroom wall 3, the situation where hot water overflows from the recess 24 of the bathtub wall 18 and easily collects on the floor surface 16 below is suppressed. can do.

なお、本発明は上述した形態に限られるものではなく、例えば凹部２４と凹部３３とは必ずしも正対して対向していなくてもよい。ただし、特に浴槽壁１８及び浴槽壁１９の対向間隔が狭い場合には、入浴者の出入り等に伴い流れようとする湯を凹部２４に集中させないように直ちに凹部３３の方に逃がす必要があるので、凹部２４と凹部３３とが正対又はそれに近い位置関係で対向していることが望ましい。また、凹部３３の高さを凹部２４の高さよりも低くすることによって、湯が浴槽８内から溢れ出そうになったときにはまず凹部２４ではなく凹部３３に向かって流れるので、入浴者の出入り等により勢い付いて流れ始めた湯のその最初の勢いを凹部３３で受け止めることができ、これにより湯が凹部２４から一気に溢れ出て床面１６に溜まる事態を抑制することができる。さらに、凹部３３に流れ込んだ湯が浴室壁３との間を流れ落ちるようにしておけば、湯が凹部２４から一気に溢れ出る事態をより確実に防止することができる。   In addition, this invention is not restricted to the form mentioned above, for example, the recessed part 24 and the recessed part 33 do not necessarily need to oppose facing each other. However, in particular, when the facing distance between the bathtub wall 18 and the bathtub wall 19 is narrow, it is necessary to immediately release the hot water that flows along with the entry and exit of the bather to the concave portion 33 so as not to concentrate on the concave portion 24. It is desirable that the concave portion 24 and the concave portion 33 face each other in a direct relationship or a positional relationship close thereto. In addition, by setting the height of the concave portion 33 lower than the height of the concave portion 24, when hot water is about to overflow from the bathtub 8, the hot water first flows toward the concave portion 33 instead of the concave portion 24. Thus, the initial momentum of the hot water that has started to flow through can be received by the concave portion 33, whereby the situation where hot water overflows from the concave portion 24 and accumulates on the floor surface 16 can be suppressed. Furthermore, if the hot water that has flowed into the recess 33 flows down between the bathroom wall 3, it is possible to more reliably prevent the hot water from overflowing from the recess 24 at a stretch.

また、入槽側の浴槽壁１８の凹部２４と、対向する浴槽壁１９の凹部３３とを正対した位置関係とすれば、浴槽壁全体としてみたとき、長手方向には高低の変動が生じているが、短手方向には常に同じ高さとなる。従って図５（ａ）に示すように浴槽蓋の例としてシャッター蓋４０を用いる場合も、図５（ｂ）に示すように組み蓋４１を用いる場合も、高い密閉性をもって蓋をすることができる。   Moreover, if it is set as the positional relationship which faced the recessed part 24 of the bathtub wall 18 in the tank side, and the recessed part 33 of the opposing bathtub wall 19, when it sees as the whole bathtub wall, the fluctuation | variation of the height will arise in the longitudinal direction. However, it is always the same height in the short direction. Therefore, even when the shutter lid 40 is used as an example of the bathtub lid as shown in FIG. 5 (a) and when the assembled lid 41 is used as shown in FIG. 5 (b), the lid can be closed with high hermeticity. .

ここで仮に一方の浴槽壁１８のみに凹部２４を設け、対向する浴槽壁１９には凹部を設けないとすれば、凹部２４の部分が封止されないため隙間が生じ、密閉性が悪くなるおそれがある。このような隙間があると浴槽からの放熱が大きく、湯を沸かすための所要時間が長くなり、また保温性も低下してしまう。また浴室内の結露も増加し、浴室全体が冷えやすくなってしまう。かといってこのような隙間を封止するために立体的な形状（例えば平面板状の蓋に、凹部を封止するためのリブを立設した構造）の浴槽蓋を構成するとすれば、成形型の著しい大型化を招く。また、立体的構造により汚れが溜まりやすく、さらに入浴中に浴槽脇に立てかけておく際の収納性が低下してしまう。   If the concave portion 24 is provided only in one bathtub wall 18 and the concave portion 24 is not provided in the opposite bathtub wall 19, the concave portion 24 may not be sealed and a gap may be formed, resulting in poor sealing performance. is there. If there is such a gap, the heat radiation from the bathtub is large, the time required for boiling the hot water becomes long, and the heat retention is also lowered. Condensation in the bathroom also increases, and the entire bathroom becomes easy to cool. However, if a bathtub lid having a three-dimensional shape (for example, a structure in which a rib for sealing a recess is erected on a flat plate-like lid) is configured to seal such a gap, molding is performed. This leads to a significant increase in mold size. Further, the three-dimensional structure tends to accumulate dirt, and further, the storage property when standing on the side of the bathtub during bathing is lowered.

しかし本実施形態の構成によれば、浴槽蓋は平面を屈曲した形状とすることができるため、成型時にはまず平面状の部材を形成し、これを屈曲させることにより容易に形成することができ、成形型の大型化を招くことがない。また図に示すように重ね合わせて立てかけることができるため、入浴中の収納性にも優れた浴槽蓋を用いることができる。   However, according to the configuration of the present embodiment, since the bathtub lid can be formed into a shape with a bent plane, it can be easily formed by first forming a planar member at the time of molding, and bending it. There is no increase in the size of the mold. Moreover, since it can pile up and stand as shown in a figure, the bathtub lid excellent also in the storage property in bathing can be used.

本発明は、ユニットバスに好適に適用可能であるが、その他の浴槽、浴室にも適用することができる。   The present invention can be suitably applied to a unit bath, but can also be applied to other bathtubs and bathrooms.
