Description

  In the present invention, a floor pan and a bathtub serving as a washing place are juxtaposed on the installation surface, and the washing place side and the bathtub side are partitioned watertight by an apron supported at the upper end of the floor pan and the washing place side of the bathtub. Relating to the bathroom unit.

  2. Description of the Related Art Conventionally, there is a bathroom unit in which a bathtub, a floor pan, a wall panel, a ceiling panel, and the like are preliminarily molded at a factory, and the molded parts are brought into the field before being assembled.

  The bathroom unit has a floor pan, a bathtub, a wall panel, an entrance / exit provided in a part of the wall panel, and a ceiling panel that closes an opening formed by the upper peripheral edge of the wall panel. Because these are assembled on-site, the assembly is easier and the construction period can be shortened compared to conventional bathrooms where tiles are attached one by one on the site and finished. Costs can be reduced by reducing the number of parts.

  Bathroom units are roughly divided into a full panel type in which a bathtub is placed on a floor pan supported on the installation surface, and a half panel type in which the bathtub and floor pan are installed side by side on the installation surface. Since the type of bathroom unit can further reduce the number of parts compared to the full-panel type, it is widely used in hotels, condominiums, and general houses.

  By the way, unlike the full panel type bathroom unit, the half panel type bathroom unit includes an apron for covering the floor pan side of the bathtub and has a structure for connecting the bathtub and the floor pan. Specifically, the apron has a structure that supports the flange of the bathtub by attaching the upper end to the lower surface of the flange of the bathtub (for example, Patent Document 1 and Patent Document 2).

In addition to being provided, an overlapping portion of another adjacent divided body is provided with an engaging recess, and the engaging protrusion is overlapped with the overlapping portion of the other divided body while the one divided body is slid in the vertical direction. When it does, it is preferable to set it as the structure which is made to engage with the said engagement recessed part, and is made into a press-contact state in the state which interposes the overlapping parts with the elastic water stop material.
In the bathroom unit according to the present invention, the apron is configured by a plurality of divided bodies, whereby the divided bodies can be attached and detached individually. In addition, the locking protrusions engage with the locking receiving portions on the overlapping surfaces of the divided bodies, and are brought into a pressure contact state, whereby the interposed water stop member receives pressure and brings the divided bodies into a watertight state. .

Moreover, it is preferable that the bathroom unit which concerns on this invention sets it as the structure which supports the flange of the said bathtub with the upper end of the support part which stands up from the said floor pan.
In the bathroom unit according to the present invention, the support portion that rises from the floor pan supports the flange of the bathtub, thereby suppressing the downward deflection of the flange and preventing contact with the apron.

  In the bathroom unit according to the present invention, when the apron is attached to the half-panel type bathroom unit, the water-tight state between the apron and the flange of the bathtub can be prevented by the water-stopping member to prevent hot water from entering. In addition, it is possible to prevent the downwardly bent flange from coming into contact with the apron main body upper end surface or the like, and to prevent the apron from being damaged.

Conventional aprons are molded with fiber reinforced plastic (FRP) to ensure strength, but FRP has lower mass productivity than acrylonitrile / butadiene / styrene copolymer synthetic resin (ABS resin) Unit manufacturing costs are rising. However, since the apron 4 described above does not receive a load from the flange 24 even when the flange 24 is bent downward due to the weight of the bather or the like, it is necessary to be molded with FRP in consideration of strength. There is no. Therefore, the production cost can be reduced by replacing the material of the apron 4 with a material (ABS resin or the like) having higher mass productivity. Further, by replacing the material of the apron 4 with a material that is easier to process than FRP, it is possible to easily form a complex shape with high design.

  Moreover, since the apron 4 mentioned above consists of two or more sheets, compared with the apron of a single board, carrying in to a spot becomes easy and construction efficiency can be improved. Moreover, since the 3rd apron division body 41 can be easily removed from the opening produced in the position pinched | interposed into the 1st apron division body 40a and the 2nd apron division body 40b, this opening is utilized as a work inspection port. Thus, operations such as height adjustment of the support legs 11 and 12 and piping construction are simplified. In particular, since this opening is in the vicinity of the drainage port 17 and the location of the drainage pipe connected to the drainage outlet 17, the drainage pipe inspection work is simplified. Moreover, since the apron 4 is not screwed in the location which is conspicuous, it is attached with good appearance.

  Further, the overlapping portions of the first (second) apron divided body 40a (40b) and the third apron divided body 41 described above are a laterally extending piece 401, a hook receiving portion 402, a stepped surface 403, a hook 411, and a side plate 412. And so on, the inundation momentum of the hot water can be dispersed at the overlapping portion, and a certain amount of intrusion of the hot water can be suppressed.

  In addition, since the fixed piece 7 described above is detachably attached to the weir portion 14 using the hook piece 70, the screw through hole 15 and the nut 72 are consumed due to frequent attachment / detachment of the third apron divided body 41, for example. In such a case, replacement with a new fixed piece 7 is facilitated.

  In the above-described embodiment, the example in which the hook 411 is bent in an upward direction has been described. However, the present invention is not limited to such an example, and may have a hook shape that bends in a direction other than upward, and the hook receiving portion 402 may have a shape corresponding thereto.
