Description

本発明は、浴槽裏面に断熱材を取付けた断熱浴槽に関するものである。   The present invention relates to a heat insulating bathtub in which a heat insulating material is attached to the back surface of the bathtub.

従来から、図３（ａ）に示すような浴槽３の裏面を断熱材１で覆う断熱浴槽が提案されている（特許文献１参照。）。入浴者は、入浴の際に浴槽フランジ３ａに腰掛けたり、浴槽側壁３ｂに凭れたりするので、このような浴槽においても、浴槽フランジ３ａや浴槽側壁３ｂを補強する構造を設けることが好ましい。   Conventionally, the heat insulation bathtub which covers the back surface of the bathtub 3 as shown to Fig.3 (a) with the heat insulating material 1 is proposed (refer patent document 1). Since the bather sits on the bathtub flange 3a or falls on the bathtub side wall 3b during bathing, it is preferable to provide a structure for reinforcing the bathtub flange 3a and the bathtub side wall 3b even in such a bathtub.

そこで、図３（ｂ）に示すような、浴槽３の浴槽側壁３ｂと浴槽フランジ３ａとがなすコーナー部に補強材２を取り付け、補強材２を設けた箇所以外の浴槽３の裏面に断熱材１を取り付けた断熱浴槽が提案されている。   Therefore, as shown in FIG. 3 (b), the reinforcing material 2 is attached to the corner portion formed by the bathtub side wall 3b and the bathtub flange 3a of the bathtub 3, and the heat insulating material is provided on the back surface of the bathtub 3 other than the portion where the reinforcing material 2 is provided. A heat insulating bathtub with 1 attached has been proposed.

しかし、このような浴槽３においては、浴槽３に補強材２と断熱材１を取り付ける作業が分かれてしまって効率が悪いという問題があった。また、浴槽３への補強材２の取付位置がずれると、予め補強材２用の空所４を設けている断熱材１が、浴槽３に取り付けられなくなってしまうという問題があった。   However, in such a bathtub 3, there was a problem that the work of attaching the reinforcing material 2 and the heat insulating material 1 to the bathtub 3 was divided and the efficiency was poor. Moreover, when the attachment position of the reinforcing material 2 to the bathtub 3 is shifted, there is a problem that the heat insulating material 1 provided with the space 4 for the reinforcing material 2 in advance cannot be attached to the bathtub 3.

また、浴槽３に取り付けた補強材２を通して、浴槽３の熱が放熱されてしまって、断熱性が悪いという問題があった。   Moreover, the heat of the bathtub 3 was radiated through the reinforcing material 2 attached to the bathtub 3, and there was a problem that heat insulation was bad.

(B) is an exploded perspective view of the other conventional heat insulation bathtub.

以下、本発明を示す実施形態に基づいて説明する。   Hereinafter, the present invention will be described based on embodiments.

実施形態１の断熱浴槽は、図１（ａ）に示すように浴槽側壁３ｂの上端に浴槽フランジ３ａを設けた浴槽３の裏面に、浴槽側壁３ｂを覆うための側壁用断熱材１ｂと、浴槽底面３ｃを覆うための底面用断熱材１ｃとを取り付けることで、形成されている。側壁用断熱材１ｂと、底面用断熱材１ｃは、一体成形されているものであっても良いし、別々に取付けるものであっても良い。側壁用断熱材１ｂは、上端面１ａが浴槽フランジ３ａに当接するように、接着剤や螺子等で、浴槽側壁３ｂの外面に重ねて取り付けられる。   As shown in FIG. 1 (a), the heat insulating bathtub of Embodiment 1 has a side wall heat insulating material 1b for covering the bathtub side wall 3b on the back surface of the bathtub 3 provided with a bathtub flange 3a at the upper end of the bathtub side wall 3b, and the bathtub. It is formed by attaching the bottom surface heat insulating material 1c for covering the bottom surface 3c. The side wall heat insulating material 1b and the bottom surface heat insulating material 1c may be integrally molded, or may be separately attached. The side wall heat insulating material 1b is attached to the outer surface of the bathtub side wall 3b by an adhesive or a screw so that the upper end surface 1a contacts the bathtub flange 3a.

側壁用断熱材１ｂの上部には、図１（ｂ）に示すように、補強材２が一体に設けられている。ここで、補強材２は、側壁用断熱材１ｂの上部から下部に亘って設けても良いが、補強材２の上端部が浴槽フランジ３ａに当接するように少なくとも上部には設けられている。補強材２の上端部には、側壁用断熱材１ｂから浴槽外側方向に突出するようフランジ支持部２ａが設けられている。また、補強材２の浴槽側壁３ｂに対向する部分には浴槽側壁対向部２ｂが設けられている。この補強材２を一体に設けた側壁用断熱材１ｂを、浴槽３の浴槽側壁３ｂの外面に重ねて取付け、補強材２のフランジ支持部２ａを浴槽フランジ３ａの下面に当接させ、浴槽側壁対向部２ｂを浴槽側壁３ｂに重ね合わせて取付けることで、浴槽フランジ３ａをフランジ支持部２ａで支持し、浴槽側壁３ｂを浴槽側壁対向部２ｂで支持し、浴槽フランジ３ａ及び浴槽側壁３ｂを補強している。   As shown in FIG. 1B, a reinforcing material 2 is integrally provided on the side wall insulating material 1b. Here, the reinforcing material 2 may be provided from the upper part to the lower part of the side wall heat insulating material 1b. However, the reinforcing material 2 is provided at least at the upper part so that the upper end of the reinforcing material 2 contacts the bathtub flange 3a. A flange support portion 2a is provided at the upper end portion of the reinforcing member 2 so as to protrude from the side wall heat insulating material 1b toward the outside of the bathtub. Moreover, the bathtub side wall opposing part 2b is provided in the part facing the bathtub side wall 3b of the reinforcing material 2. As shown in FIG. The side wall heat insulating material 1b integrally provided with the reinforcing material 2 is attached to the outer surface of the bathtub side wall 3b of the bathtub 3, and the flange supporting portion 2a of the reinforcing material 2 is brought into contact with the lower surface of the bathtub flange 3a, thereby By attaching the opposing portion 2b to the bathtub side wall 3b so as to be superposed, the bathtub flange 3a is supported by the flange support portion 2a, the bathtub side wall 3b is supported by the bathtub side wall opposing portion 2b, and the bathtub flange 3a and the bathtub side wall 3b are reinforced. ing.

このような構成とすることで、側壁用断熱材１ｂを、浴槽側壁３ｂに重ねて取付けるだけで、補強材２と側壁用断熱材１ｂとを浴槽側壁３ｂに同時に取付けることができる。よって、取り付け作業が１つになって効率が良い。また、図３（ｂ）に示す従来例のように、浴槽側壁３ｂに補強材２を個別に取り付ける必要もなければ、側壁用断熱材１ｂに、予め補強材２用の空所４を設ける必要もないので、補強材２の浴槽３への取付位置がずれて、断熱材１が浴槽３に取り付けられなくなってしまうといったことを防止することができるので、組み立て性が良くなる。   By setting it as such a structure, the reinforcing material 2 and the heat insulating material 1b for side walls can be simultaneously attached to the bathtub side wall 3b only by attaching the heat insulating material 1b for side walls on the bathtub side wall 3b. Therefore, the installation work becomes one and the efficiency is good. Further, as in the conventional example shown in FIG. 3B, if it is not necessary to individually attach the reinforcing material 2 to the bathtub side wall 3b, a space 4 for the reinforcing material 2 needs to be provided in advance in the side wall heat insulating material 1b. Therefore, it is possible to prevent the attachment position of the reinforcing material 2 to the bathtub 3 from being shifted and the heat insulating material 1 from being attached to the bathtub 3, thereby improving the assemblability.

ここで、図１（ｂ）に示すように、実施形態１の浴槽側壁対向部２ｂは、浴槽側壁３ｂに直接取付けられている。このようにフランジ支持部２ａと浴槽側壁対向部２ｂとが２辺をなす三角形状断面の補強材２で、浴槽フランジ３ａと浴槽側壁３ｂとを夫々、直接支持することで、強固に補強することができる。ここで、補強材２は、三角形状断面であったが、フランジ支持部２ａと浴槽側壁対向部２ｂとが、浴槽フランジ３ａと浴槽側壁３ｂとを夫々、直接支持する形状であれば、他の形状であっても良い。   Here, as shown in FIG.1 (b), the bathtub side wall opposing part 2b of Embodiment 1 is directly attached to the bathtub side wall 3b. In this way, the reinforcing member 2 having a triangular cross section in which the flange supporting portion 2a and the bathtub side wall facing portion 2b form two sides, and the bathtub flange 3a and the bathtub side wall 3b are directly supported to reinforce strongly. Can do. Here, the reinforcing member 2 has a triangular cross section. However, if the flange support portion 2a and the bathtub side wall facing portion 2b have shapes that directly support the bathtub flange 3a and the bathtub side wall 3b, respectively, It may be a shape.

また、補強材２は、フランジ支持部２ａと、浴槽側壁対向部２ｂとを除く部分が、側壁用断熱材１ｂで囲まれていて、補強材２を設けた部分が、浴槽側壁３ｂに、浴槽側壁用断熱材１ｂと、補強材２とを、補強材２、側壁用断熱材１ｂの順番で重ねた三層構造になっている。このように、補強材２を設けた部分が、三層構造になることで、補強材２を通して浴槽３の熱が放熱されることを、側壁用断熱材１ｂで防止することができる。   Further, in the reinforcing material 2, the portion excluding the flange support portion 2a and the bathtub side wall facing portion 2b is surrounded by the side wall insulating material 1b, and the portion provided with the reinforcing material 2 is attached to the bathtub side wall 3b. It has a three-layer structure in which the side wall insulating material 1b and the reinforcing material 2 are stacked in the order of the reinforcing material 2 and the side wall insulating material 1b. Thus, the heat insulating material 1b for side walls can prevent that the heat | fever of the bathtub 3 is thermally radiated through the reinforcing material 2 because the part which provided the reinforcing material 2 becomes a three-layer structure.

次に本発明の実施形態２に示す断熱浴槽は、図２に示すように、補強材２が、ある一定の厚みで、側壁用断熱材１ｂの浴槽外側面全面を覆うように一体に設けられている。補強材２の上端部の一部には、側壁用断熱材１ｂの浴槽外側面から浴槽外側方向にコ字状に突出するようフランジ支持部２ａが設けられている。フランジ支持部２ａの下部の補強材２は、フランジ支持部２ａを最突出端として、下方に行くにつれて、突出量を減らすように傾斜する構成となっている。ここで、補強材２の突出にあわせて側壁用断熱材１ｂも突出している。また、突出した補強材２の浴槽側壁３ｂに対向する部分には、浴槽側壁対向部２ｂが設けられている。この補強材２を一体に設けた側壁用断熱材１ｂを、浴槽３の浴槽側壁３ｂの外面に重ねて取付け、補強材２のフランジ支持部２ａを浴槽フランジ３ａの下面に当接させ、浴槽側壁対向部２ｂを、側壁用断熱材１ｂを介して、浴槽側壁３ｂに重ね合わせて取付けている。よって、側壁用断熱材１ｂの突出部の両端において、フランジ支持部２ａと浴槽側壁対向部２ｂとが２辺をなす三角形状断面の補強材２で、浴槽フランジ３ａを直接支持し、尚且つ、側壁用断熱材１ｂを介して浴槽側壁３ｂを支持することで、浴槽フランジ３ａと浴槽側壁３ｂを補強している。また、補強材２は側壁用断熱材１ｂの浴槽外側面全面を覆うような構成となっているので、浴槽フランジ３ａと浴槽側壁３ｂとを強固に支えることができる。   Next, as shown in FIG. 2, the heat insulating bathtub shown in Embodiment 2 of the present invention is provided integrally with the reinforcing material 2 so as to cover the entire outer surface of the bathtub of the side wall heat insulating material 1 b with a certain thickness. ing. A flange support portion 2a is provided on a part of the upper end portion of the reinforcing member 2 so as to protrude in a U-shape from the bath outer surface of the side wall heat insulating material 1b toward the bath outer side. The reinforcing member 2 below the flange support portion 2a is configured to be inclined so as to reduce the protrusion amount as it goes downward with the flange support portion 2a as the most protruding end. Here, the side wall heat insulating material 1 b also protrudes in accordance with the protrusion of the reinforcing material 2. Moreover, the bathtub side wall opposing part 2b is provided in the part which opposes the bathtub side wall 3b of the protruding reinforcing material 2. As shown in FIG. The side wall heat insulating material 1b integrally provided with the reinforcing material 2 is attached to the outer surface of the bathtub side wall 3b of the bathtub 3, and the flange support portion 2a of the reinforcing material 2 is brought into contact with the lower surface of the bathtub flange 3a. The facing portion 2b is attached to the bathtub side wall 3b so as to overlap with the side wall heat insulating material 1b. Therefore, at both ends of the protruding portion of the side wall heat insulating material 1b, the flange support portion 2a and the bathtub side wall facing portion 2b have a triangular cross-section reinforcing material 2 to directly support the bathtub flange 3a, and The bathtub flange 3a and the bathtub side wall 3b are reinforced by supporting the bathtub side wall 3b through the side wall insulating material 1b. Moreover, since the reinforcing material 2 is configured to cover the entire outer surface of the bathtub outer surface of the side wall insulating material 1b, the bathtub flange 3a and the bathtub side wall 3b can be firmly supported.

以上の構成とすることで、実施形態２においても、補強材２を設けた側壁用断熱材１ｂを、浴槽側壁３ｂに重ねて取付けるだけで、補強材２と側壁用断熱材１ｂとを浴槽側壁３ｂに同時に取付けることができる。よって、取り付け作業が１つになって効率が良い。また、図３（ｂ）に示す従来例のように、浴槽側壁３ｂに補強材２を個別に取り付ける必要もなければ、側壁用断熱材１ｂに、予め補強材２用の空所４を設ける必要もないので、補強材２の浴槽３への取付位置がずれて、断熱材１が浴槽３に取り付けられなくなってしまうといったことを防止することができるので、組み立て性が良くなる。   With the above configuration, also in Embodiment 2, the side wall heat insulating material 1b provided with the reinforcing material 2 is attached to the bathtub side wall 3b so that the reinforcing material 2 and the side wall heat insulating material 1b are attached to the bathtub side wall. 3b can be attached simultaneously. Therefore, the installation work becomes one and the efficiency is good. Further, as in the conventional example shown in FIG. 3B, if it is not necessary to individually attach the reinforcing material 2 to the bathtub side wall 3b, a space 4 for the reinforcing material 2 needs to be provided in advance in the side wall heat insulating material 1b. Therefore, it is possible to prevent the attachment position of the reinforcing material 2 to the bathtub 3 from shifting and the heat insulating material 1 from being attached to the bathtub 3, thereby improving the assemblability.

また、側壁用断熱材１ｂの浴槽外側面全面を覆うように一体に補強材２を設けた側壁用断熱材１ｂを、浴槽側壁３ｂに取付けているので、補強材２を設けた部分が、浴槽側壁３ｂに、浴槽側壁用断熱材１ｂと、補強材２とを、その順番で重ねた三層構造になっている。このように、補強材２を設けた部分が、三層構造になることで、浴槽３の熱が放熱されることを、側壁用断熱材１ｂで防止することができる。   Moreover, since the side wall heat insulating material 1b integrally provided with the reinforcing material 2 so as to cover the entire outer surface of the bathtub outer surface of the side wall heat insulating material 1b is attached to the bathtub side wall 3b, the portion provided with the reinforcing material 2 is The side wall 3b has a three-layer structure in which the bathtub side wall insulating material 1b and the reinforcing material 2 are stacked in that order. Thus, since the part which provided the reinforcing material 2 becomes a three-layer structure, it can prevent that the heat | fever of the bathtub 3 is thermally radiated with the heat insulating material 1b for side walls.
