Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit bath, and more particularly, to a joint between a top edge of a bathtub and a wall panel of a stationary unit bath, which can be easily constructed without skill, and has an aesthetic appearance. And a unit bath that can be expected to improve hygiene.

[0002]

2. Description of the Related Art Generally, in a stationary unit bath, a bathtub is installed on a bathtub waterproof pan close to a wall panel. In this case, a gap is generated between the upper edge of the bathtub and the wall panel. If hot water leaks from this gap, hot water accumulates on the bathtub waterproof pan below the bathtub, resulting in an unsanitary condition. Therefore, conventionally, as shown in FIG. 4, in the gap between the upper edge portion (B) of the bathtub (A) and the wall panel (C), silicon (E) together with the backup material (D) is used as a joint material. Is filling.

[0003]

However, in the joint construction for filling the silicon (E), it is necessary to prevent the silicon (E) from adhering to unnecessary parts by applying a masking tape. In this case, considerable skill is required to apply the masking tape according to the shape of the upper edge portion (B) of the bathtub (A). Further, there is silicon (E) having poor adhesion depending on the material of the bathtub (A), and it is necessary to prepare a plurality of types of silicon (E) according to the material of the bathtub (A). Furthermore, in a high-temperature and high-humidity environment in a bathroom, mold is easily generated on the silicon (E), which not only deteriorates aesthetic appearance but also causes inconvenience.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a joint between an upper edge portion of a bathtub and a wall panel easily without requiring skill, and to provide an aesthetically pleasing appearance. An object of the present invention is to provide a unit bath that can be expected to improve hygiene.

[0005]

As a means for achieving the above object, the present invention provides a bathtub having an upper edge turned downward is installed on a bathtub waterproof pan, and the upper edge of the bathtub and its surroundings are installed. In a unit bath in which a joint material is provided in a gap between the wall panel and the joint material, the joint material has a fixed piece joined to the wall panel and a rising piece facing the inside of the folded portion of the bathtub upper edge. It is characterized by the following.

[0006] It is preferable that the joint material is provided with a drainage gradient toward the washing basin waterproof pan adjacent to the bathtub waterproof pan.
In addition, it is preferable to sandwich a waterproof packing between the rising piece of the joint material and the folded portion of the upper edge of the bathtub.
Further, the fixing piece of the joint material is preferably joined to the wall panel via a waterproof packing. The joint material may be made of a soft resin, and a ridge for sealing may be integrally formed on the joint surface with the wall surface.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A unit bus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing constituent members of a unit bus according to an embodiment and an engagement relationship therebetween, FIG. 2 is a cross-sectional view showing a schematic overall structure of the unit bus, and FIG. FIG.

As shown in FIGS. 1 and 2, a unit bath according to an embodiment comprises a bathtub waterproof pan (1) and a washing place waterproof pan (2) which are formed continuously and integrally, and a bathtub waterproof pan (1). ) And each wall panel (3) erected on the washing pan waterproof pan (2) to partition the bathroom, and a bathtub (4) installed on the bathtub waterproof pan (1). An apron (5) is arranged in front of 4). Note that these components are usually formed of a heat-resistant thermoplastic resin or thermosetting resin.

In the present invention, a bathtub (4) whose upper edge (4a) is folded downward is installed on the bathtub waterproof pan (1), and the upper edge (4a) of the bathtub (4) and its surroundings are provided. A joint material (6) is arranged in a gap between each of the wall panels (3). Then, as shown in FIG. 3, the joint material (6) faces the fixing piece (6a) joined to each wall panel (3) and the inside of the folded portion (4b) of the upper edge portion (4a) of the bathtub. And a rising piece (6b).

The joint material (6) is made of a heat-resistant thermoplastic resin or thermosetting resin formed in a channel shape with the rising piece (6b) as one side wall.
A drain groove (6d) having a drain gradient in the longitudinal direction is formed between b) and the other side wall (6c) continuous with the upper end of the fixing piece (6a). The fixing piece (6a) of the joint material (6) is joined and fixed to each wall panel (3) by a screw (8) via a waterproof packing (7).
When the drainage groove (6d) does not have a drainage gradient, each joint material (6) is slightly inclined so as to have a drainage gradient toward the washing pan waterproof pan (2). Fix to 3).

The rising piece (6b) of the joint material (6) has a stepped cross-sectional shape extending along the inside of the upper edge (4a) of the bathtub (4). A waterproof packing (9) is sandwiched between the edge (4a), that is, between the folded portion (4b) and the flat portion (4c) continuous with the folded portion (4b).

The waterproof packings (7) and (9) are as follows:
Any type of tape may be used as long as the tape is continuous in the longitudinal direction of the joint material (6). In the present embodiment, an adhesive tape made of a closed-cell foam is used in consideration of workability. Have been.

In the unit bath according to the present embodiment, each joint in which the waterproof packing (7) is attached to the fixing piece (6a) and the waterproof packing (9) is attached to the rising piece (6b). The material (6) is previously bonded and fixed to a predetermined portion of each wall panel (3). When the bathtub (4) is placed on the bathtub waterproof pan (1), the rising pieces (6b) of the joint members (6) are folded back (4a) of the bathtub upper edge (4a).
Adjust the position of the bathtub (4) so that it is joined to the inside of b) via the waterproof packing (9). By this adjusting work, joint work between the upper edge portion (4a) of the bathtub (4) and each wall panel (3) is completed easily without skill.

In the unit bath thus completed, the hot water overflowing from the upper edge (4a) of the bathtub (4) is caught by the drain (6d) of each joint material (6), and is washed in the washing place. The water is drained to the pan (2) side to prevent water from leaking onto the bathtub waterproof pan (1). At that time, since each joint material (6) has a drainage gradient toward the washing basin pan (2), hot water overflowing from the bathtub (4) is smoothly drained to the washing basin pan (2). In addition, each joint material (6)
And a waterproof packing (7) between the wall panel (3) and the folded portion (4b) of the bathtub (4).
Since (9) is interposed, water leakage onto the bathtub waterproof pan (1) is reliably prevented.

Therefore, in the unit bath of the present embodiment, the situation in which hot water stays on the waterproof tub (1) below the bathtub (4) and rots is prevented beforehand.
Extremely hygienic. In addition, since the joint material (6) is less likely to generate mold than silicon used in conventional joint construction, it is possible to maintain the appearance for a long period of time.

The joint material in the present invention is not limited to the joint material (6) configured as described above. For example, the wall panel (3) and the bathtub (4) may be made of a soft resin in which a sealing ridge is integrally formed on a joint surface of the upper edge (4a) and the folded portion (4b). .

[0017]

As described above, according to the present invention, the joint material is joined to the wall panel, and the rising piece faces the inside of the folded portion of the upper edge of the bathtub, whereby the upper edge of the bathtub is exposed. The joint construction between the panel and the wall panel is basically completed. Therefore, the joint around the upper edge of the bathtub can be easily constructed without skill. In addition, since the joint material is less likely to generate mold than silicon, improvement in aesthetics and hygiene can be expected.
