Description

本発明は、浴槽載置用の浴槽防水パンと、この浴槽防水パンに載置する浴槽及び壁パネルと、エプロンで構成される浴室ユニットに関する。   The present invention relates to a bathtub waterproofing pan for bathtub mounting, a bathtub and a wall panel mounted on the bathtub waterproofing pan, and a bathroom unit including an apron.

従来、浴室ユニットの浴槽設置方法としては、浴槽載置用の浅型浴槽防水パンの外縁部に壁パネルを載置させ、その載置した壁パネルの内周面に、浴槽の洗場側を除く３辺のフランジ部を当接させて、浴槽を浴槽防水パン上に設置する方法が知られている。   Conventionally, as a bathtub installation method of a bathroom unit, a wall panel is placed on the outer edge of a shallow bathtub waterproof pan for placing a bathtub, and the washbasin side of the bathtub is placed on the inner peripheral surface of the placed wall panel. There is known a method of placing a bathtub on a bathtub waterproof pan by bringing the flanges on the other three sides into contact with each other.

また、別な浴室ユニットの浴槽設置方法として、浴槽の洗場側を除く３辺のフランジ部に壁パネルを載置させ、浴槽と壁パネルとエプロンと洗場パンを水密に接合することで、浴槽載置用の浴槽防水パンを用いない設置方法が知られている。
しかし、集合住宅や戸建の２階以上に浴室ユニットを設置する場合に、浴槽及び止水部からの漏水防止対策として、浴槽の外周を覆う様に浴槽囲いパンを設置する方法が知られている。 Moreover, as another bathtub installation method of a bathroom unit, by placing a wall panel on the flanges on the three sides excluding the washroom side of the bathtub, and joining the bathtub, the wall panel, the apron, and the washbasin in a watertight manner, There is known an installation method that does not use a bathtub waterproofing pan for bath mounting.

浴室ユニットにおいて浴槽防水パンを用いる構造では、特許文献１に記載の図１の通り、浴槽防水パンと壁パネルとを水密に構成し、壁パネル組立後に浴槽を設置することで、新たな漏水防止対策を行う必要がなく、また、浴槽はその設置構造から比較的交換を容易に行う事ができ、リホーム等で浴槽を入替えする場合に有利な構成を提供できる。
しかし、特許文献１に記載の図１の構造では、浴槽の漏水対策が不要な設置場所でも、浴槽防水パンや浴槽フランジ部よりも下部に延設する長尺の壁パネルを使用しなければならず、コスト低減を図ることができない。 In the structure using the bathtub waterproof pan in the bathroom unit, as shown in FIG. 1 described in Patent Document 1, the bathtub waterproof pan and the wall panel are watertightly constructed, and the bathtub is installed after the wall panel is assembled, thereby preventing new water leakage. There is no need to take measures, and the bathtub can be replaced relatively easily from its installation structure, and an advantageous configuration can be provided when the bathtub is replaced by rehome or the like.
However, in the structure of FIG. 1 described in Patent Document 1, a long wall panel that extends below the bathtub waterproof pan and the bathtub flange must be used even in an installation location that does not require measures against water leakage in the bathtub. Therefore, the cost cannot be reduced.

また、浴室ユニットで浴槽囲いパンを用いる構造では、特許文献１に記載の図５の様に浴槽囲いパンは浴槽より大型化するため、浴槽囲いパン製造用の金型費用や部材コストが嵩み、漏水対策コストが割高になる。そこでコスト低減方法として特許文献２に記載の図２１に示すように、浴槽防水パンと周囲壁とを分割してコスト増を抑制する方法が開示されているが、新たに専用の浴槽防水パンを用意する必要があり、また分割型浴槽囲いパンを用いる場合、浴槽囲い壁を浴槽防水パンへ固定する部品が増加する為、大幅なコスト低減は望めなかった。   Moreover, in the structure using a bathtub enclosure pan in a bathroom unit, since the bathtub enclosure pan is larger than the bathtub as shown in FIG. 5 described in Patent Document 1, the mold cost and the member cost for producing the bathtub enclosure pan are increased. The cost of water leakage countermeasures is expensive. Therefore, as shown in FIG. 21 described in Patent Document 2 as a cost reduction method, a method of dividing the bathtub waterproof pan and the surrounding wall to suppress the cost increase has been disclosed. In the case of using a split-type bathtub enclosure pan, it is not possible to expect a significant cost reduction because the number of parts for fixing the bathtub enclosure wall to the bathtub waterproof pan increases.

本発明は、前記の従来の問題点に鑑みてなされたものであって、浴槽防水パンを使用する浴室ユニットの浅型の浴槽防水パンを、分割型浴槽囲いパンへ流用可能な浴室ユニットの提供を目的とする。
また、本発明は前記浴槽防水パンに止水部材を設けた係合部材を使用することで、止水パッキン及び機械固定を必要としない分割型浴槽囲いパンを搭載した、浴室ユニットの提供を目的とする。 The present invention has been made in view of the above-described conventional problems, and provides a bathroom unit capable of diverting a shallow bathtub waterproof pan of a bathroom unit using a bathtub waterproof pan to a split bathtub enclosure pan.

従って、Ｕ型溝３ｂの底部に浴槽囲い壁４の下端部を嵌合した状態において浴槽囲い壁４の側面と内側係止片３Ｂの内面との間に若干の隙間を生じるが、この隙間に止水ヒレ３ａ、３ａが延在していて隙間を閉じるので、浴槽囲い壁４と下部係合部材３との間の水密性が向上されている。なお、図３に示す横断面においては止水ヒレ３ａ、３ａの状態を見やすくするために、浴槽囲い壁４が嵌合されていない状態の止水ヒレ３ａ、３ａの位置を示しているが、浴槽囲い壁４をＵ型溝３ｂに嵌合した状態において止水ヒレ３ａ、３ａは浴槽囲い壁４と内側係止片３Ｂとの間の隙間に挟まれて下向きに延在する。   Therefore, in the state where the lower end of the bathtub enclosure wall 4 is fitted to the bottom of the U-shaped groove 3b, a slight gap is generated between the side surface of the bathtub enclosure wall 4 and the inner surface of the inner locking piece 3B. Since the water stop fins 3a and 3a extend and close the gap, the watertightness between the bathtub enclosure wall 4 and the lower engaging member 3 is improved. In addition, in order to make it easy to see the state of the water stop fins 3a and 3a in the cross section shown in FIG. 3, the position of the water stop fins 3a and 3a in a state where the bathtub enclosure wall 4 is not fitted is shown. In a state in which the bathtub enclosure wall 4 is fitted in the U-shaped groove 3b, the water stop fins 3a and 3a are sandwiched by a gap between the bathtub enclosure wall 4 and the inner locking piece 3B and extend downward.

また、延出片３Ｄの先端側にも斜め下向きに延出する軟質樹脂製の止水ヒレ（止水部材）３ｇが形成されていて、凸部３Ａを外縁凹部２ｃに嵌合して延出片３Ｄを側壁２Ｂの上端部に沿わせた場合、止水ヒレ３ｇが側壁２Ｂの上端部に接触して延出片３Ｄと側壁２Ｂの間の水密性を高める構造とされている。図３ではこの止水ヒレ３ｇにおいても側壁２Ｂの上端部と接触していない状態として示したが、実際に延出片３Ｄを側壁２Ｂの上に載置した状態では止水ヒレ３ｇが側壁の上端部に沿って被着される。
これらの止水ヒレ３ａ、３ｇを設けていることで、下部係合部材３を浴槽防水パン２に嵌合し、下部係合部材３に浴槽囲い壁４を嵌合する操作のみで、固定及び水密を確保できる為、浴槽囲い壁４は複雑な形状が不要となり、金型投資費用の低減と、汎用板材採用可能によりコスト低減を図ることができる。 Further, a water stop fin (water stop member) 3g made of a soft resin that extends obliquely downward is also formed on the distal end side of the extension piece 3D, and the protrusion 3A is fitted into the outer edge recess 2c to extend. When the piece 3D is placed along the upper end portion of the side wall 2B, the water stop fin 3g comes into contact with the upper end portion of the side wall 2B to increase the water tightness between the extending piece 3D and the side wall 2B. In FIG. 3, the water stop fin 3g is also shown as not in contact with the upper end of the side wall 2B. However, when the extension piece 3D is actually placed on the side wall 2B, the water stop fin 3g is It is applied along the upper end.
By providing these water stop fins 3a and 3g, only the operation of fitting the lower engagement member 3 to the bathtub waterproof pan 2 and fitting the bathtub enclosure wall 4 to the lower engagement member 3 can be fixed and fixed. Since the watertightness can be ensured, the bathtub enclosure wall 4 is not required to have a complicated shape, and cost can be reduced by reducing the investment cost of the mold and adopting a general-purpose plate material.
