Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom unit formed of a bathroom floor set and a bathtub.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
1 is provided with a bathtub installation portion 22 on one side of the bathroom floor set 2, and a bathtub fitting opening 23 is formed in the center of the bathtub installation portion 22, and the bathtub 3 is fitted into the bathtub fitting opening 23. Then, the upper frame 31 provided around the entire circumference of the bathtub 3 is installed on the peripheral edge portion 24 of the bathtub fitting opening 23, and the bathroom floor set 2
The bathroom unit 1 in which the bathroom wall 11 is erected on the periphery of is frequently used. In such a bathroom unit 1, unless the watertightness is maintained between the peripheral edge portion 24 of the bathtub fitting opening 23 of the bathroom floor set 2 and the upper frame 31 of the bathtub 3, the hot and cold water of the bathroom floor set 2 is kept. It will spill under the floor of the building through the opening 23 for fitting in the bathtub. As a conventional watertight structure in this portion, for example, a structure described in Japanese Utility Model Laid-Open No. 4-79589 is devised.

As shown in FIG. 5, an upper frame 31 is provided around the entire circumference of the bath tub 3, and a lower edge 32 is provided below the outer end of the upper frame 31 and the bathroom. A projecting edge portion 24a that is integrally erected is formed on a peripheral edge portion 24 of the bathtub fitting opening 23 formed in the bathtub setting portion 22 of the floor set 2, and is made of an aluminum alloy in parallel with the projecting edge portion 24a. The watertight frame 4 of the upper frame 31 and the lower edge 3 are provided.
2, the protruding edge portion 24a and the watertight frame 4 are inserted, and the watertight material 5 is interposed between the upper frame 31 and the peripheral edge portion 24 of the bathtub fitting opening 23, so that the bathtub 3 is moved to the peripheral edge portion 24. is set up.

The watertight member 5 has a substantially T-shaped cross section, and the lower half 51 thereof is sandwiched between the projecting edge 24a and the watertight frame 4, and the fixing screw 6 is provided at an appropriate position thereof. The fixing spacer 7 is provided so as to penetrate therethrough, and the upper end surface of the upper half portion 52 of the watertight material 5 is in contact with the back surface of the upper frame 31. Further, a space between the lower portion of the watertight frame 4 and the peripheral portion 24 is sealed by a silicon sealing 8.

[0005]

However, the conventional bathroom unit requires a watertight frame for holding the watertight material, and the assembling work is complicated. In addition, there is a problem in that the cost of the members and the number of man-hours required for the installation are relatively high.In addition, due to variations in the degree of tightening of the watertight frame installation, the gap between the projecting edge and the watertight frame is not uniform, and the removal of the watertight material is not possible. There was a problem of easy detachment and insufficient water tightness. The present invention has been made in view of such a problem in the conventional bathroom unit, and an object of the present invention is to provide a bathroom unit that is easy to construct, does not remove the watertight material, and can be reliably watertight. To do.

[0006]

To achieve the above object, in the bathroom unit according to the invention described in claim 1, a bathtub fitting opening is formed in the bathtub installation portion, and the bathtub fitting opening is formed. The two protruding edges are integrally provided on the peripheral edge of the bathtub, and the lower half of the watertight material is fitted into the groove formed between the protruding edges, and the bathtub is fitted into the bathtub fitting opening. The upper end surface of the watertight member is pressed against the lower surface of the upper frame provided at the upper end of the.

In the bathroom unit according to the second aspect of the present invention, a bathtub fitting opening is formed in the bathtub installation portion, and a concave groove is formed upward at the peripheral edge of the bathtub fitting opening. The lower half of the watertight material is fitted in the groove, and the upper end surface of the watertight material is pressed against the lower surface of the upper frame provided at the upper end of the bathtub fitted in the opening for fitting the bathtub. .

[0008]

In the bathroom unit of the present invention constructed as described above, the groove formed between the two projecting edges integrally provided at the peripheral edge of the bathtub fitting opening or the bathtub fitting. A watertight material is fitted in a groove integrally formed in the peripheral portion of the insertion opening, the lower half of which is fitted, and the upper end surface of which is pressed against the lower surface of the upper frame of the bathtub. Therefore, even if the bathtub moves, the watertight material is not removed from the bathtub fitting body, and watertightness can be ensured, and the watertight material can be easily attached without using the watertight material attachment member.

That is, according to the first aspect of the present invention, the watertightness can be ensured simply by fitting and mounting the watertight material in the groove between the projecting edges at the peripheral edge of the bathtub fitting opening.

Further, according to the second aspect of the invention, the watertightness can be surely secured by simply fitting the watertight material into the concave groove of the peripheral edge of the bathtub fitting opening.

[0011]
