By the way, in the conventional bathroom unit 1, the fixing method of the bathtub apron 4 is only fitting by the shape of the molded products of the bathtub apron 4 and the bathtub apron support member 21. FIG. If it does so, the clearance gap between the bathtub apron 4 and the wash basin waterproofing bread 3 may become large by the dispersion | variation in a product tolerance and construction tolerance.
That is, as shown in FIG. 8, a gap P may be formed between the lowest wall portion 37 of the bathtub apron 4 and the wall portion 38 of the wash basin waterproof pan 3.
Thereby, even if a water stop member is attached to the gap, there is a repulsive force of the water stop member itself, so that the water stop performance cannot be ensured without being sufficiently compressed.
As a result, water and steam sprinkled from the wash basin waterproof pan 3 passed through the gap between the bathtub apron 4 and the wash basin waterproof pan 3, and entered the tub side.
When water or steam enters the bathtub side from the wash basin waterproofing pan 3, the water often contains dirt such as human sebum, so the user of the bathroom unit 1 regularly cleans it. There was an inconvenience that had to be done.

  Therefore, as a method of fixing the bathtub apron 4, a method of mechanically fixing the bathtub apron 4 and the wash basin waterproof pan 3 can be considered. Thereby, the bathtub apron 4 fitting part can reliably stop the water on the bathtub 2 installation surface, and prevents the entry of dirty water and steam from the wash basin waterproofing pan 3 to the bathtub 2 installation surface. , You can eliminate regular cleaning.

  However, as a method of fixing the machine, a method of fixing the bath apron 4 and the wash basin waterproof pan 3 with a screw or the like is conceivable, but in this method, it is necessary to process a pilot hole in the wash basin waterproof pan 3. However, since the demolding direction at the time of forming the wash basin waterproof pan 3 and the prepared hole processing direction are perpendicular to each other, the prepared hole cannot be formed at the rising portion of the wash basin waterproof pan 3 at the time of forming. Therefore, the pilot hole processing is a post-processing step after molding, and the number of manufacturing steps of the wash basin waterproof pan 3 is increased.

  In addition, it is usually necessary to periodically check the hot water supply pipe installed on the building side, the memorial pipe attached to the bathtub 2 and the equipment of the bubble bath. Therefore, the bathtub apron 4 needs to be able to be repeatedly detached and to withstand repeated desorption operations.

  Under such a background, there has been a demand for a fixing structure for the bath apron 4 which has a structure in which the bath apron 4 can be repeatedly detached without providing the wash-basin waterproof pan 3 itself with a screw fixing pilot hole. Since it is difficult to achieve both the water stop structure and the simplification of maintenance and inspection work, the actual situation is that an effective and appropriate one is not provided.

  The present invention has been made in consideration of such circumstances, and its purpose is to firmly fix the bathtub apron and the wash basin waterproofing pan mechanically to compress the water stop member to ensure water stop and to wash the water. It is to provide a fixing structure of a bath apron that can be repeatedly attached and detached without drilling a pilot hole in a bath apron fitting portion of a field waterproof pan.

(1) The present invention includes a bathtub, a wash basin waterproof pan disposed adjacent to the bathtub, and a bathtub apron disposed along a side surface of the bathtub, and the upper end of the bathtub apron is the upper end of the bathtub. The bathroom waterproof pan has a rising wall portion that rises in the bathtub apron direction in the vicinity of the bathtub, and the rising wall portion and a side wall portion of the lower end of the bathtub apron. And the rising wall portion includes a first rising wall portion engaged with the bathtub apron and the water blocking member, and the first rising wall. A second rising wall portion that is positioned on the bathtub side from the first portion and extends further upward than the first rising wall portion, and the bathtub apron is joined to the first rising wall portion, Located between the second rising wall and the bathtub apron A first wall portion having a female screw hole, and a sandwiching portion connected to the first wall portion and configured to sandwich and hold the second rising wall portion from the bathtub side and the bathtub apron side A screw that penetrates the side wall of the lower end of the bathtub apron is screwed into the female screw hole of the locking member, and the side wall of the lower end of the locking member and the apron of the bathtub is secured by the screw. The present invention relates to a bathroom unit characterized in that it is tightened to form the water stop structure.
(2) The present invention relates to a bathroom unit in which a nut is embedded in the thickness direction of the first wall portion.

In the present invention, as a result of adopting the above-described configuration, the method for fixing the wash basin waterproof pan and the bath apron is to tighten the water with a screw to obtain a water stop structure. The effect that it can be performed is obtained.
In addition, the screw tightens the bathtub apron and the locking member that is locked to the wash basin waterproof pan, so that the wash basin pan is drilled at the production plant and at the local construction site. There is an effect that it becomes unnecessary.
Furthermore, by using a screw, it becomes possible to repeatedly detach the bathtub apron, and the building-side hot water supply pipe connection portion can be periodically inspected. In addition, because of a general fastening method of screwing using a screw, there is no complicated structure, and the effect that the inspection worker can easily understand the method of attaching and detaching the bath apron is obtained.
