[Industrial applications]

 The present invention relates to a bathtub / waterproof pan combination set including a waterproof pan having a floor part for a washing room and a bathtub fitting hole, and a bathtub fitted into the bathtub fitting hole of the waterproof pan.

[0002]

[Prior art]

 As a conventional bathtub / waterproof pan combination set, for example, there is a bathroom unit described in Japanese Patent Publication No. 57-43250. FIG. 8 is a perspective view of the bathroom unit, and FIG. 9 is a sectional view of the bathroom unit. 10 and 11 are enlarged cross-sectional views of the portion where the bathtub is fitted into the bathtub fitting hole.

The waterproof pan 1 is manufactured by FRP, and has a wash floor 2 and a bathtub fitting hole 3 formed therein. Then, a bathtub 4 made of FRP, stainless steel or the like can be fitted into the bathtub fitting hole 3 to form a bathroom part having the bathtub 4, the wash floor 2 and the waist wall 5, and the floor waterproofing. The aim is to make it easy to construct a complete bathroom.

As shown in FIG. 9, the structure of the portion where the bathtub 4 is fitted into the bathtub fitting hole 3 is such that the rising wall 6 is formed in the peripheral portion of the bathtub fitting hole 3 of the waterproof pan 1. The upper part of the peripheral wall of the bathtub 4 is bent outward to form an upper surface portion 7, and the edge of the upper surface portion 7 is bent downward to form a vertical surface portion 8. It is fitted from above, and the back surface of the upper surface portion 7 of the bathtub 4 rides on the top portion of the rising wall 6 of the waterproof pan 1.

In order to prevent water leakage from the portion where the bathtub 4 is fitted into the bathtub fitting hole 3, for example, as shown in FIG. 10, the back surface of the upper surface 7 of the bathtub 4 and the rising of the waterproof pan 1 are raised. The bathtub 4 is placed with an elastic packing material 9 having watertightness interposed between it and the top of the wall 6.

It should be noted that the gap between the substantially horizontal step portion 10 formed at the base of the rising wall 6 in the peripheral portion of the bathtub fitting hole 3 of the waterproof pan 1 and the lower end edge of the vertical surface portion 8 of the bathtub 4 is waterproofed. There is also an example in which the elastic caulking material 11 is embedded.

Further, as shown in FIG. 11, not only is the elastic packing material 9 installed on the top of the rising wall 6, but also a substantially horizontal step portion 10 and a bathtub 4 formed on the base portion of the rising wall 6 of the waterproof pan 1. There is also an example in which a watertight frame 12 having a packing material attached to the upper and lower edges of the frame body is also interposed between the upper surface portion 7 and the back surface thereof to completely prevent water leakage.

[0008]

[Problems to be solved by the device]

 However, in the conventional bathtub / waterproof pan combination set such as the above bathroom unit, when the bathtub 4 is filled with hot and cold water, the bathtub 4 becomes heavy due to the structure of the watertightness and the characteristics of the elastic packing material attached. Along with the phenomenon that the packing material is strongly compressed to exert a watertight effect and at the same time the bathtub slightly sinks, and when the hot and cold water in the bathtub is discharged, the bathtub 4 becomes lighter and is slightly lifted by the elastic packing material.

Due to the load fluctuation and vertical movement of the bathtub occurring as described above, an abnormal noise is generated at the contact portion between the waterproof pan 1 and the bathtub 4, and further, the FRP itself used as the material is apt to produce a squeak noise. As a result, there was a problem of causing discomfort and anxiety.

Further, in the example in which the elastic caulking material 11 is embedded in the gap between the lower end of the vertical surface portion 8 of the bathtub 4 and the waterproof pan 1, the generation of squeaking noise is reduced by caulking, but caulking is reduced. In some cases, construction is troublesome and difficult and requires a lot of time. There are also problems that the appearance of the caulking material is impaired due to dirt and mold, and it is necessary to remove the caulking material during maintenance work, which is troublesome.

Further, in the case of using the watertight frame 12, in addition to the above problems, there is a problem that the cost becomes high.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is possible to fit the bathtub in a watertight state in the bathpane fitting hole of the waterproof pan, which causes discomfort and safety. It is an object of the present invention to provide a bathtub / waterproof pan combination set that reduces or prevents the generation of audible noise.

[0013]
