Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a bathtub device in a bathroom provided with a bathroom unit consisting of a wall panel, a waterproof floor, and a bathtub.

(Prior art) Conventionally, as a bath kettle device, for example,
As described in Publication No. 54119, a balanced bath pot that is attached to the side of a bathtub is used in a bathroom, but a balanced bath pot is also used when using a large bathtub with a large space inside the bathtub. Therefore, the bathtub cannot be expanded to a larger size. By the way, in order to meet the demand for using a large bathtub, we removed the balance type bathtub and the exhaust pipe of the bathtub provided in the through hole of the bathroom outer wall, and installed a bathtub with approximately the same dimensions as the exhaust pipe on the outer wall. It has been devised that the space of a balanced bathtub can be expanded by installing it in a through hole as space within the bathtub.

However, in order to install a bathtub accommodated in such an outer wall through-hole in a bathroom, as shown in FIG. An opening 4' is drilled at a position corresponding to the through hole 2', and a connecting tube 6' is inserted into the opening 4' and the through hole 2' to connect them, so that the outer peripheral surface of the connecting tube 6' and the through hole 2' are connected. A gap formed between the connecting tube 6' and the inner circumferential surface of the connecting tube 6' is filled with mortar 7' to fix the connecting tube 6' in the through hole 2'. In this way, the storage case 5 is placed inside the connecting tube 6' into which the opening 4' and the through hole 2' are inserted.
A bathtub 5' having a mounting flange 52' provided at 1' is inserted and attached from the inside of the wall panel 3'. In this case, since the outer peripheral surfaces of the mortar 7' and the connecting pipe 6' are not completely bonded, when the bathtub 5' swings due to external wind pressure, etc., a concentrated load is applied to the opening 4' of the wall panel 3'. The wall panel 3' is prone to fall and vibrate, so there are drawbacks such as the need to use a stronger wall panel 3' or to reinforce the periphery of the opening 4'.

(Purpose of the invention) The present invention solves the above-mentioned drawbacks, and provides a bath kettle device for a bathroom in which the bath kettle is fitted into a connecting cylinder fixed in a through hole in the outer wall of the bathroom. be.

(Structure of the invention) Next, an embodiment of the invention will be described based on the drawings.

1 is an outer wall of the bathroom, and the outer wall 1 is provided with a through hole 2.

Reference numeral 3 denotes a wall panel of the bathroom unit, which is close to the outer wall 1, and the wall panel 3 is placed on a waterproof floor (not shown) installed in the bathroom.

An opening 31 having substantially the same opening size as the through hole 2 is formed in the wall panel 3 at a position corresponding to the through hole 2 .

4 is an angular connecting tube with one end folded back outward to form a flange 41, and the connecting tube 4 connects the through hole 2 of the outer wall 1 and the opening 3 of the connecting panel 3.
1 are connected.

Reference numeral 5 designates a bathtub with a through-hole in the outer wall, and the bathtub 5 is inserted into the connecting tube 4 and placed in the through-hole 2 .

Reference numeral 6 denotes a protrusion, which is composed of an embedded bolt part 61 having a female thread installed therein, and a mounting screw 62 that can be screwed onto the bolt part 61.

In order to fix the connecting tube 4 in the through hole 2 of the outer wall 1 of the bathroom using the embedded bolt part 61, the third
As shown in the figure, insert the mounting screw 62 of the protrusion 6 into the hole 42 provided in the bottom wall of the connecting cylinder 4 from inside the connecting cylinder 4, and insert the embedded bolt part 61 from the outside of the connecting cylinder 4 into the mounting screw 62. After screwing into the connecting tube 4 and forming a protrusion 6 that protrudes downward from the bottom wall of the connecting tube 4, a thick layer of mortar 7 is applied to the inner surface of the through hole 2, and the connecting tube 4 is penetrated from the inside of the wall panel 3. Insert into hole 2,
The protrusion 6 is buried and fixed in mortar 7.

In this way, the connecting tube 4 is inserted into the through hole 2 of the outer wall 1 of the bathroom, the through hole 2 and the opening 31 are connected by the connecting tube 4, and then the bathtub is attached to the storage case with a mounting flange. 5 into the connecting tube 4 from the inside of the wall panel 3.

(Effects of the invention) Since the present invention is constructed as described above, the protrusion of the connecting tube can be embedded and fixed in the mortar applied to the inner circumferential surface of the through hole, and the projection can be fixed inside the connecting tube. Since the bathtub fitted into the bathtub does not sway due to external wind pressure, etc., there is no possibility that a concentrated load will be applied to the opening of the wall panel or that the wall panel will vibrate. Therefore, it is not necessary to use a wall panel 3 with high strength or to reinforce the periphery of the opening 4.

Furthermore, if the protrusion protruding outward of the connecting tube is made up of an embedded bolt part with a female thread installed therein, and a mounting screw that can be screwed into the bolt part,
When renovating a bathroom wall panel, it is convenient because the connecting tube can be easily removed and the wall panel replaced by simply loosening the mounting screws.
