Description

  The present invention relates to a bathtub used for a bathroom unit.

  Conventionally, a bathroom unit includes, for example, a waterproof pan in which a washing place and a bathtub mounting portion are continuously provided, a bathtub installed in a bathtub mounting portion (waterproof pan under the bathtub) of the waterproof pan, and a peripheral edge of the waterproof pan ( In many cases, a structure is used that is constituted by a wall panel that stands up around the periphery of the waterproof pan and the bathtub and a ceiling panel that covers the upper opening formed by these wall panels.

  The bathroom unit basically has the above-described structure, but the structure of the members forming the bathroom is roughly divided into two systems. One of them is a waterproof pan (hereinafter sometimes referred to as a bath-mounted waterproof pan) in which a washing place and a bathtub mounting portion are connected as described above, a wall panel surrounding the periphery, and a ceiling panel. And a structure comprising a bathtub and a waterproof pan disposed under the bathtub. In this case, a waterproof pan in which the washing place and the bathtub mounting portion are formed as separate bodies and both are connected with an appropriate connector may be used (for example, see Patent Document 1).

  The other one is a structure in which the waterproof pan is composed only of a washing pan, and includes a peripheral wall panel, a ceiling panel, and a bathtub, and has a structure without the waterproof pan under the bathtub (for example, Patent Documents). 2).

  As an example of the former, a bathroom unit specifically described in Patent Document 1 has a washing area and a bathtub basin, and the bathtub is installed on the bathtub basin. , And the washing place part and the bathtub installation part are configured separately, and the peripheral wall part of the peripheral edge of the bathtub installation part is configured to have substantially the same height.

  Moreover, as a latter example, the bathroom unit described in Patent Document 2 is a bathroom unit in which a wall panel is erected around a bathtub and a waterproof pan. The bathtub is a bathtub installation member having a bathtub insertion opening and a standing wall portion. The tub is installed by hooking the peripheral edge of the tub to the fitting opening.

  However, in the two methods of the bathroom unit described above, the conventional bathtubs are not compatible with each other, and it is necessary to prepare products having different specifications for each type of waterproof pan. For this reason, when both are manufactured, there is a problem that a large amount of capital investment and manufacturing cost are required because dedicated dies and members are required.

JP-A-8-144342 JP-A-7-67802

  In view of the above-mentioned conventional problems, the object of the present invention is to provide a waterproof pan that is only provided in a washing place when a bathtub-mounted waterproof pan is provided, that is, a waterproof pan is provided under the bathtub. The object is to provide a bathtub that can be shared to form a bathroom unit.

  The present invention has been made to achieve the above object, and has formed a bathroom unit in which wall panels are erected on the four circumferences of a waterproof pan in which a washing place and a bathtub mounting portion are continuously provided, and a washing place. A bathtub for use in a bathroom unit in which wall panels are erected on the three sides except the bathtub side of the waterproof pan and wall panels are erected on the three sides except for the washing side of the bathtub tub The peripheral edge of the part is formed in a rectangular shape in plan view, and the wall panel placement part and the water return wall erected on the outer side are formed on the peripheral edges of the three sides excluding the washing area side of the bathtub bowl. This is a featured bathtub.

The bathtub of this invention is provided with the bottom face part, the side wall part standingly arranged in the circumference | surroundings, and the collar part formed in the upper edge of this side wall part.
The material of the bathtub body can be any of those conventionally used for bathtub materials, and is not particularly limited. For example, synthetic resin such as FRP and acrylic resin, wood, enameled cast iron, stainless steel, etc. Inorganic materials such as metals and artificial marble can be used.

The collar portion may have a flat plate shape, a refractive shape, and an end portion may be folded downward. Moreover, you may make it into the step shape of two steps or more upwards from the upper edge of a side wall part. In order to obtain a comfortable tactile sensation for bathers, corners and corners may be rounded. The periphery of the collar portion is formed in a rectangular shape in plan view.
A flat portion having a thickness equal to or greater than the wall panel thickness is provided at the periphery of the collar portion on the three sides excluding the washing area side, and is used as a wall panel placement portion. In this case, a peripheral edge shall point to the site | part outside from the bathtub of the uppermost surface of a collar part. Although the wall panel thickness is usually about 1 mm to 20 mm, although it depends on the material and configuration of the wall panel, the width of the flat portion is usually 1 mm to 20 mm or more. The buttock functions as a handrail, an armrest, and a headrest for the bather, and it is desirable that the buttock has a width that can be visually felt comfortably. It is desirable that it is about 300 mm. If it is too small, the above function is impaired. If it is too large, the bathtub becomes large and expensive.

  A water return wall is provided on the peripheral edge of the ridges on the three sides excluding the washing area on the outer side of the wall panel mounting portion in the vertical direction. It is desirable that the height of the water return wall is normally about 10 mm to 100 mm from the flat portion. If it is too small, water from the bathtub may leak through the wall panel. If it is too large, the bathtub becomes large and expensive. The thickness of the water return wall is preferably about the thickness of the bathtub body. Usually, it is desirable to be about 1 mm to 20 mm. If it is too thin, it is easily damaged. If it is too thick, the weight increases and the cost becomes high.

  The water return wall may be integrated with a hanging wall with a water return wall extending downward from the flange portion, and may form a flat plate extending vertically in the vertical direction from the periphery of the flange portion as a whole. In this case, in order to contact the wall panel, it is necessary to form a flat surface on the outside. Further, the flat portion and the corner of the water return wall may have a right-angle shape, or may have a somewhat rounded shape. Since both the inner and outer surfaces of the water return wall may be arranged so that the wall panels are in contact with each other, it is desirable that the water return wall be flat.

The material of the water return wall can be the same as the material of the bathtub described above. Although not particularly limited, for example, synthetic resins such as FRP and acrylic resin, metals such as wood, enameled cast iron and stainless steel, and inorganic materials such as artificial marble can be used.
The method of forming the water return wall may be integrally formed simultaneously with the bathtub, or may be previously formed by a plate material and bonded to the bathtub body.

  For example, the wall panel is formed by bonding a gypsum board as a backing material to the back of a PVC steel plate or FRP plate, and a gypsum board as a backing material is bonded to an intermediate layer of a two-layer PVC steel plate or FRP plate And those formed by bonding a plastic foam material or the like as a backing material to the back surface of a PVC steel plate or FRP plate. The left and right edges of the PVC steel plate and FRP are preferably used with bent portions formed on the back side to prevent water from entering between the layers.

  Between the butted part of the adjacent wall panel and the lower end edge of the wall panel and the peripheral edge of the waterproof pan, the wall panel mounting part on the peripheral edge of the three sides of the bathtub, and in some cases, the inner surface of the wall panel and the water return wall, Between the outer surfaces and the like, silicon coking is filled to ensure water tightness. Silicon caulking may be filled after bonding with an adhesive such as epoxy.

The material of the waterproof pan that forms the washing area and the bathtub-mounted waterproof pan has a waterproof function and is excellent in strength. Although not particularly limited, for example, synthetic resins such as FRP and acrylic resin, metals such as wood, enameled cast iron and stainless steel, and inorganic materials such as artificial marble can be used. A wash floor may be formed by attaching tiles or the like to the waterproof pan of the wash area.
In the present invention, the waterproof pan in which the washing place and the bathtub mounting portion are continuously provided is a waterproof pan disposed under the bathtub, and the washing place and the bathtub mounting portion are integrally formed and continuously provided. In many cases, both are formed as separate bodies and include a waterproof pan that is connected by an appropriate connector.
Hereinafter, the waterproof pan in which the washing area and the bathtub mounting portion are continuously provided may be referred to as a bathtub mounting waterproof pan.
Further, in the present invention, the waterproof pan in which the washing place is formed is a waterproof pan including only the washing place in which the bathtub stationary part is not formed, and is used when the waterproof pan is not provided under the bathtub.

The present invention relates to a bathroom unit in which a wall panel is erected on the four circumferences of a waterproof pan in which a washing place and a bathtub mounting portion are continuously provided, and a wall panel on three sides excluding the bathtub side of the waterproof pan that forms the washing place Is a bathtub used in a bathroom unit in which wall panels are erected on the three sides excluding the washing area side of the bathtub bowl, and the periphery of the bathtub bowl is formed in a rectangular shape in plan view. This is a bathtub in which the wall panel mounting part and the water return wall standing on the outside are formed on the periphery of the three sides excluding the washing room side of the bathroom, so a bathtub mounting type waterproof pan is installed under the bathtub When a waterproof pan with a washing area is used, that is, when a waterproof pan is not installed under the bathtub, it is possible to provide a bathtub that can be shared with a wall panel to make a bathroom unit. .
