DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a door pan mounting structure.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing a waterproof pan for a bathroom unit, a hand lay-up molding method, a press molding method using an SMC (sheet molding compound), and the like have been used. The hand lay-up method is inferior in productivity in terms of speed and cannot be mass-produced, but the mold cost is easy.

[0003] On the other hand, the press molding method is not suitable for the production of many kinds because the production speed is high but the mold cost is high. Therefore, 3 floors of the washing floor except the bathtub side
There has been proposed a waterproof pan in which all the edges are formed at the same height (see JP-A-8-232316).

That is, in this waterproof pan, the doors can be attached to all three edges at the same straddling height by making the three edges of the floor of the washing area all the same height. As a result, a type of waterproof pan can be used in various bathrooms with different door positions to reduce costs.

[0005] By the way, in the conventional bathroom unit as described above, as shown in FIG. 9, the door pan 100 is attached to a rib 201 provided on the back surface of the waterproof pan 200.
The hanging piece 101 and the rib 201 are screwed to the waterproof pan 200 with a tapping screw 300 or the like in a state in which the hanging piece 101 hanging from the edge of the waterproof pan 200 abuts. Filling the gap with a sealing agent 400 such as a silicone resin sealing agent prevents the outflow of hot water or water from the door pan 100 side to the back side of the waterproof pan 200.

However, in the above-described door pan mounting structure, a step of screwing the door pan to the waterproof pan is performed,
Sealant 4 is applied to the gap between door pan 100 and waterproof pan 200.
Since the method has a step of filling with 00, the workability is poor. In addition, if the operator is not a skilled worker, the filling of the sealant 400 may be insufficient, and a sufficient sealing state may not be secured.

[0007]

SUMMARY OF THE INVENTION In view of such circumstances, the present invention provides a bathroom unit that can easily attach a door pan to a waterproof pan and can reliably seal a gap between the door pan and the waterproof pan. The purpose of the present invention is to provide a door pan mounting structure.

[0008]

SUMMARY OF THE INVENTION In order to achieve such an object, a door pan mounting structure for a bathroom unit according to the present invention receives a door frame from below at a doorway portion of a waterproof pan forming a bathroom washing area. In the door pan mounting structure of the bathroom unit in which the door pan is screwed to the waterproof pan, a part of the door pan is arranged so as to face the bottom surface of the waterproof pan from below, and an elastic sealing material is interposed between the pan and the waterproof pan. In this state, the screw was fixed to the waterproof pan.

In the present invention, the waterproof pan may have a washing pan part forming a washing place and a bathtub pan part for receiving a bathtub may be integrated or may be divided. Further, the bathtub may be set such that a flange-shaped portion provided at an upper end thereof is locked to a frame-shaped member commonly called glasses.
