Abstract
Description
本発明は浴槽に関するものである。 The present invention relates to a bathtub.
特許文献１は従来の浴槽を開示している。この浴槽は、背もたれ部、及び枕部を備えている。背もたれ部は、水平面に対して約２０度に傾斜し、入浴者の背中が当接する背もたれ面を有している。枕部は、背もたれ面を上方へ延長した仮想延長面よりも上方に位置し、入浴者の後頭部が当接する枕面を有している。この枕面は水平面に対する傾斜が背もたれ部よりも急である。入浴者は、後頭部を枕面に当接し、仰向け状態でこの浴槽に入浴する。このため、入浴者は、身体が浮力によって浮遊状態になり、リラックスして入浴することができる。 Patent document 1 is disclosing the conventional bathtub. This bathtub is provided with a backrest part and a pillow part. The backrest portion is inclined at about 20 degrees with respect to the horizontal plane and has a backrest surface against which the bather's back comes into contact. The pillow portion is positioned above a virtual extension surface obtained by extending the backrest surface upward, and has a pillow surface with which the back of the bather comes into contact. This pillow surface is steeper than the backrest with respect to the horizontal plane. The bather contacts the back of his head with the pillow surface and bathes in this bathtub in a supine state. For this reason, a bather becomes a floating state by buoyancy, and can take a bath relaxed.
しかし、この浴槽は、入浴者の身体が浮力によって浮遊状態になるため、入浴姿勢が安定しない。特に、身体の小さい入浴者は、後頭部を枕面に当接させた入浴姿勢をとると、両足を着くべき所定の場所に着くことができず、想定した入浴姿勢をとることができない。このため、身体の小さい入浴者は、浮力によって浮遊状態になると、後頭部が枕面に当接するのみとなり、入浴姿勢がより安定しない。 However, the bathing posture of the bathtub is not stable because the body of the bather is floated by buoyancy. In particular, if a bather with a small body takes a bathing posture in which the back of the head is in contact with the pillow surface, the bather cannot reach a predetermined place where both feet should be worn and cannot take the assumed bathing posture. For this reason, when a bather with a small body enters a floating state due to buoyancy, the back of the head only comes into contact with the pillow surface, and the bathing posture is less stable.
本発明は、上記従来の実情に鑑みてなされたものであって、安定した入浴姿勢でリラックスして入浴することができる浴槽を提供することを解決すべき課題としている。 This invention is made | formed in view of the said conventional situation, Comprising: It is the problem which should be solved to provide the bathtub which can be relaxed and bathed with the stable bathing attitude | position.
本発明の浴槽は、貯湯部と、
入浴者の背中が当接する背もたれ面を有した背もたれ部と、
前記背もたれ面を上方へ延長した仮想延長面よりも前方に位置し、前記入浴者の後頭部が当接する枕面を有した枕部とを備え、
前記枕部は、前記枕部の下部に開口した吐水口が設けられており、
前記吐水口は、前記貯湯部の上端よりも下方に設けられていることを特徴とする。
The bathtub of the present invention comprises a hot water storage section,
A backrest portion having a backrest surface against which the bather's back abuts,
A pillow portion having a pillow surface that is positioned in front of a virtual extension surface that extends the backrest surface upward, and against which a back head of the bather abuts,
The pillow part is provided with a water spout opening at the lower part of the pillow part,
The water outlet is provided below the upper end of the hot water storage section.
この浴槽は、入浴者の後頭部が当接する枕面が、背もたれ面を上方へ延長した仮想延長面よりも前方に位置している。このため、入浴者が後頭部を枕面に当接させ、背中を背もたれ面に当接させた入浴姿勢をとると、入浴者の重心が、入浴者に働く浮力の作用点である浮心に対して水平方向で近づくので、入浴者の入浴姿勢が安定する。したがって、本発明の浴槽によれば、入浴者は、安定した入浴姿勢でリラックスして入浴することができる。また、この浴槽の枕部は、枕部の下部に開口した吐水口が設けられている。このため、入浴姿勢の入浴者の肩に温水を吐水することができるので、入浴中のリラックス効果をより一層高めることができる。さらに、この浴槽の吐水口は、貯湯部の上端よりも下方に設けられている。このため、吐水口から吐水された温水が、入浴者の身体を伝って貯湯部の外に流れてしまうことを防止することができる。 In this bathtub, the pillow surface against which the bather's back head abuts is positioned in front of the virtual extension surface extending the backrest surface upward. For this reason, if the bather takes a bathing posture in which the back of the head is brought into contact with the pillow surface and the back is brought into contact with the backrest surface, the bather's center of gravity is The bathing posture of the bather is stabilized. Therefore, according to the bathtub of the present invention, the bather can relax and take a bath in a stable bathing posture. Moreover, the pillow part of this bathtub is provided with the spout opening opened to the lower part of the pillow part. For this reason, since warm water can be sprinkled on the shoulder of the bather of a bathing attitude | position, the relaxation effect during bathing can be improved further. Furthermore, the water outlet of this bathtub is provided below the upper end of the hot water storage section. For this reason, it can prevent that the warm water discharged from the water outlet flows out of a hot water storage part along a bather's body.

このような構成を有する浴槽は、入浴者Ｈの後頭部が当接する枕面３２Ｓが、背もたれ面３１Ｓを上方へ延長した仮想延長面Ｘよりも前方に位置し、水平面に対する傾斜が背もたれ面３１Ｓよりも急であるため、入浴者Ｈが後頭部を枕面３２Ｓに当接させ、背中を背もたれ面３１Ｓに当接させた入浴姿勢をとると、浮力を受けない入浴者Ｈの頭部の荷重を水平方向で入浴者Ｈの身体の重心（腰のあたり）に近づけることができる。よって、入浴者Ｈの頭部の荷重が身体に受けた浮力を打消すように働き、入浴姿勢を安定させることができる。また、入浴者Ｈの身体の大小にかかわらず、この浴槽は後頭部を枕面３２Ｓに当接させ、背中を背もたれ面３１Ｓに当接させた入浴姿勢をとることができるため、入浴姿勢を安定させることができる。 In the bathtub having such a configuration, the pillow surface 32S with which the back head of the bather H abuts is positioned in front of the virtual extension surface X extending the backrest surface 31S upward, and the inclination with respect to the horizontal plane is more than the backrest surface 31S. Since the bather H takes a bathing posture in which the back of the head is in contact with the pillow surface 32S and the back is in contact with the backrest surface 31S, the load on the head of the bather H not receiving buoyancy is horizontal. Can be brought close to the center of gravity (around the waist) of the body of the bather H. Therefore, the load of the bather H's head works so as to counteract the buoyancy received by the body, and the bathing posture can be stabilized. Further, regardless of the body size of the bather H, this bath can take a bathing posture in which the back of the head is brought into contact with the pillow surface 32S and the back is brought into contact with the backrest surface 31S, so that the bathing posture is stabilized. be able to.
したがって、実施例１の浴槽は安定した入浴姿勢でリラックスして入浴することができる。 Therefore, the bathtub of Example 1 can relax and take a bath in a stable bathing posture.
また、この浴槽は、座面３３Ｓが背もたれ部３１の下端部に向けて下り傾斜しているため、入浴者Ｈの臀部が背もたれ面３１Ｓの下部に当接した正しい入浴姿勢を入浴者Ｈは容易にとることができる。このため、入浴者Ｈは安定した入浴姿勢でリラックスして入浴することができる。 In addition, since the seat surface 33S is inclined downward toward the lower end portion of the backrest portion 31, the bather H can easily take a correct bathing posture in which the buttocks of the bather H are in contact with the lower portion of the backrest surface 31S. Can be taken. For this reason, the bather H can relax and take a bath in a stable bathing posture.

When the pump 73 is driven, the hot water in the hot water storage section 10 flows from the inlet 72, and the hot water can be discharged from the water outlet 71 toward the shoulder of the bather H in the bathing posture through the circulation path 74.
このような構成を有する浴槽は、入浴者Ｈの後頭部が当接する枕面６２Ｓが、背もたれ面６１Ｓを上方へ延長した仮想延長面Ｘよりも前方に位置し、水平面に対する傾斜が背もたれ面６１Ｓよりも急であるため、入浴者Ｈが後頭部を枕面６２Ｓに当接させ、背中を背もたれ面６１Ｓに当接させた入浴姿勢をとると、浮力を受けない入浴者Ｈの頭部の荷重を水平方向で入浴者Ｈの身体の重心（腰のあたり）に近づけることができる。よって、入浴者Ｈの頭部の荷重が身体に受けた浮力を打消すように働き、入浴姿勢を安定させることができる。また、入浴者Ｈの身体の大小にかかわらず、この浴槽は後頭部を枕面６２Ｓに当接させ、背中を背もたれ面６１Ｓに当接させた入浴姿勢をとることができるため、入浴姿勢を安定させることができる。 In the bathtub having such a configuration, the pillow surface 62S with which the back of the bather H comes into contact is positioned in front of the virtual extension surface X extending the backrest surface 61S upward, and the inclination with respect to the horizontal plane is more than that of the backrest surface 61S. Since the bather H takes a bathing posture in which the back of the head is brought into contact with the pillow surface 62S and the back is brought into contact with the backrest surface 61S, the load on the head of the bather H not receiving buoyancy is horizontal. Can be brought close to the center of gravity (around the waist) of the body of the bather H. Therefore, the load of the bather H's head works so as to counteract the buoyancy received by the body, and the bathing posture can be stabilized. Further, regardless of the body size of the bather H, this bathtub can take a bathing posture in which the back of the head is brought into contact with the pillow surface 62S and the back is brought into contact with the backrest surface 61S, so that the bathing posture is stabilized. be able to.
したがって、参考例の浴槽も、安定した入浴姿勢でリラックスして入浴することができる。 Therefore, the bathtub of the reference example can also relax and take a bath with a stable bathing posture.
また、この浴槽は、座面６３Ｓが背もたれ部６１の下端部に向けて下り傾斜しているため、入浴者Ｈの臀部が背もたれ面６１Ｓの下部に当接した正しい入浴姿勢を入浴者Ｈは容易にとることができる。このため、入浴者Ｈは安定した入浴姿勢でリラックスして入浴することができる。 Further, in this bathtub, since the seat surface 63S is inclined downward toward the lower end portion of the backrest portion 61, the bather H can easily take a correct bathing posture in which the buttocks of the bather H are in contact with the lower portion of the backrest surface 61S. Can be taken. For this reason, the bather H can relax and take a bath in a stable bathing posture.
また、この浴槽は、一体に形成した背もたれ部６１、枕部６２、及び座部６３は、貯湯部１０に着脱自在であるため、背もたれ部６１、枕部６２、及び座部６３の有無を選択することができる。また、既設の浴槽等に背もたれ部６１、枕部６２及び座部６３を取り付けることによって、入浴者Ｈは安定した入浴姿勢でリラックスして入浴することができる。 Moreover, since the backrest part 61, the pillow part 62, and the seat part 63 which were formed integrally in this bathtub are removable to the hot water storage part 10, the presence or absence of the backrest part 61, the pillow part 62, and the seat part 63 is selected. can do. Moreover, by attaching the backrest part 61, the pillow part 62, and the seat part 63 to the existing bathtub or the like, the bather H can relax and take a bath in a stable bathing posture.
＜実施例２＞
実施例２の浴槽は、図５に示すように、背もたれ面８１Ｓ及び枕面８２Ｓが同一の曲率で後方に僅かに凹むように上下方向に湾曲した湾曲面で形成されている。他の構成は実施例１と同様であり、同一の構成は同一の符号を付し、詳細な説明を省略する。
<Example 2>
As shown in FIG. 5, the bathtub of the second embodiment is formed of a curved surface that is curved in the vertical direction so that the backrest surface 81S and the pillow surface 82S are slightly recessed backward with the same curvature. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.
この浴槽の背もたれ部８１は、上下方向の略中央部において、水平面に対する傾斜角αが約５０度の背もたれ面８１Ｓを有している。湾曲した背もたれ面８１Ｓの水平面に対する傾斜角とは背もたれ面８１Ｓの上下方向の接線が水平面に対して形成する傾斜角に相当する。入浴者Ｈが入浴姿勢をとると、この背もたれ面８１Ｓの下部に入浴者Ｈの臀部が当接し、上部に背中が当接することになる。 The bathtub backrest 81 has a backrest surface 81S having an inclination angle α of about 50 degrees with respect to a horizontal plane at a substantially central portion in the vertical direction. The inclination angle of the curved backrest surface 81S with respect to the horizontal plane corresponds to the inclination angle formed by the tangent line in the vertical direction of the backrest surface 81S with respect to the horizontal plane. When the bather H takes a bathing posture, the buttocks of the bather H come into contact with the lower part of the backrest surface 81S, and the back comes into contact with the upper part.
この浴槽の枕部８２は背もたれ面８１Ｓの上端部における上下方向の接線に沿って上方へ延長した仮想延長面Ｙよりも前方に位置した枕面８２Ｓを有している。この湾曲した枕面８２Ｓは、上下方向の略中央部における上下方向の接線が、仮想延長面Ｙに対して約７度の傾斜角βを有している。つまり、枕面８２Ｓは上下方向の接線の水平面に対する傾斜が仮想延長面Ｙよりも急であり、背もたれ面８１Ｓよりも急である。また、枕面８２Ｓは貯湯部１０の上端（各フランジ部２１、２２、２３）よりも高い位置に設けられている。入浴者Ｈが入浴姿勢をとると、この枕面８２Ｓに入浴者Ｈの後頭部が当接することになる。枕面８２Ｓは、入浴者Ｈの後頭部を安定して支持できるように上下方向が１５０ｍｍ以上の長さであるとよい。 The pillow portion 82 of this bathtub has a pillow surface 82S positioned in front of a virtual extension surface Y extending upward along a vertical tangent line at the upper end portion of the backrest surface 81S. The curved pillow surface 82S has an inclination angle β of about 7 degrees with respect to the virtual extension surface Y in the vertical tangent at the substantially central portion in the vertical direction. In other words, the pillow surface 82S is steeper than the virtual extension surface Y with respect to the horizontal plane of the tangent line in the vertical direction and steeper than the backrest surface 81S. Moreover, the pillow surface 82S is provided at a position higher than the upper end (each flange portion 21, 22, 23) of the hot water storage portion 10. When the bather H takes a bathing posture, the back of the bather H comes into contact with the pillow surface 82S. The pillow surface 82S may have a length of 150 mm or more in the vertical direction so that the back of the bather H can be stably supported.
このような構成を有する浴槽は、入浴者Ｈの後頭部が当接する枕面８２Ｓが、背もたれ面８１Ｓの上端部における上下方向の接線に沿って上方へ延長した仮想延長面Ｙよりも前方に位置し、上下方向の接線の水平面に対する傾斜が背もたれ面８１Ｓよりも急である。つまり、背もたれ面８１Ｓ及び枕面８２Ｓが後方に凹むように上下方向に湾曲している浴槽であっても、入浴者Ｈが後頭部を枕面８２Ｓに当接させ、背中を背もたれ面８１Ｓに当接させた入浴姿勢をとると、浮力を受けない入浴者Ｈの頭部の荷重を水平方向で入浴者Ｈの身体の重心（腰のあたり）に近づけることができる。よって、入浴者Ｈの頭部の荷重が身体に受けた浮力を打消すように働き、入浴姿勢を安定させることができる。また、入浴者Ｈの身体の大小にかかわらず、この浴槽は後頭部を枕面８２Ｓに当接させ、背中を背もたれ面８１Ｓに当接させた入浴姿勢をとることができるため、入浴姿勢を安定させることができる。 In the bathtub having such a configuration, the pillow surface 82S with which the back of the bather H comes into contact is positioned in front of the virtual extension surface Y that extends upward along the vertical tangent line at the upper end portion of the backrest surface 81S. The slope of the tangent line in the vertical direction with respect to the horizontal plane is steeper than the backrest surface 81S. That is, even in a bathtub that is curved in the vertical direction so that the backrest surface 81S and the pillow surface 82S are recessed backward, the bather H makes the back of the head abut against the pillow surface 82S and the back abuts against the backrest surface 81S. If the bathing posture is taken, the load on the head of the bather H who does not receive buoyancy can be brought close to the center of gravity (around the waist) of the body of the bather H in the horizontal direction. Therefore, the load of the bather H's head works so as to counteract the buoyancy received by the body, and the bathing posture can be stabilized. In addition, regardless of the size of the bather H, this bathtub can take a bathing posture with the back of the head in contact with the pillow surface 82S and the back in contact with the backrest surface 81S, so that the bathing posture is stabilized. be able to.
したがって、実施例２の浴槽も安定した入浴姿勢でリラックスして入浴することができる。 Therefore, the bathtub of Example 2 can also relax and take a bath in a stable bathing posture.
