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. The gap 21' created between the connecting tube 6' and the inner peripheral surface of the through hole 2' is filled with mortar 7'.
It is fixed inside. In this way, the bathtub 5' is provided with the mounting flange 52' on the storage case 51' within the connecting tube 6' inserted into the opening 4' and the through hole 2'.
Insert and attach from the inside of the wall panel 3'. In this case, it is difficult to uniformly fill the mortar 7', and it takes too much time to wait for the mortar 7' to solidify. Since the mortar 7' alone cannot support the weight of the bathtub 5', the connecting tube 6' is inserted between the through hole 2' and the wall panel 3'. For reasons such as not being supported horizontally between the opening 4' and the outer peripheral surfaces of the mortar 7' and the connecting tube 6' not being completely bonded,
When the bathtub 5' swings inward and outward of the outer wall 1' of the bathroom due to external wind pressure, etc., a concentrated load is applied to the opening 4' of the wall panel 3', and the wall panel 3' vibrates. Therefore, there are disadvantages such as the need to use a strong 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.

The wall panel 3 has an opening 31 formed at a position corresponding to the through-hole 2 and having an opening size substantially equal to that of the through-hole 2 .

Reference numeral 4 denotes an angular connecting tube, which includes a cylindrical portion 41 provided along the circumferential direction with a mounting piece 44 that protrudes outward in the middle of the outer peripheral surface in the longitudinal direction, and a cylindrical portion 41 that protrudes outward at one end. A flange member 42 provided with a flange 43 is formed separately, and the opening 31 of the wall panel 3 of the through hole 2 of the outer wall 1 is connected by the connecting tube 4.
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 .

To fix the connecting tube 4 in the through hole 2 of the outer wall 1 of the bathroom, before placing the wall panel 3 on the waterproof floor, insert the cylindrical portion 41 of the connecting tube 4 into the through hole from the inside of the outer wall 1 of the bathroom. After the mounting piece 44 is fixed to the wall surface 11 at the peripheral edge of the through hole 2 with screws 6, the wall panel 3 is placed on a waterproof floor. Incidentally, after the cylindrical portion 41 is attached to the peripheral wall surface 11 of the through hole 2, the gap 21 created between the outer peripheral surface of the connecting tube 4 and the inner peripheral surface of the through hole 2 may be filled with mortar. Next, the flange member 42 is installed by inserting one end of the flange member 42 into the cylindrical portion 4 from inside the wall panel 3.
1, fix the flange 43 to the peripheral edge 32 of the opening 4 of the wall panel 3 with screws, and insert the connecting screw 61 from the inner surface of the connecting tube 4 into the elongated hole of the flange member 42 to tighten the screw of the tube 41. By screwing into the hole 411, the cylindrical portion 41 and the flange member 42 are connected.

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) As described above, the connecting tube is configured such that the mounting piece of the tube part is attached to the outer wall and the flange of the flange member is attached to the wall panel, and the connection tube is fixed at two places. The bathtub fitted into the cylinder does not shake due to external wind pressure, etc., so there is no possibility that concentrated loads will be applied to the opening of the wall panel.
Wall panels do not vibrate and generate noise. Therefore, it is not necessary to use a strong wall panel or to reinforce the periphery of the opening.

In addition, in the present invention, it is not necessary to uniformly fill the gap between the through hole and the outer peripheral surface of the connecting tube with mortar, and it is not necessary to fill the mortar evenly into the gap between the through hole and the outer peripheral surface of the connecting tube. Even when inserted, the tubular part attached to the wall surface by the mounting piece can always maintain the bath horizontally, making filling the mortar easier and reducing the time required to install the bathtub.

Furthermore, in the present invention, since the cylindrical portion and the flange member of the connecting tube are detachably attached, when renovating the bathroom wall panel, the connecting flange portion can be easily removed by loosening the connecting screws, etc., and the wall panel can be replaced. It is convenient to be able to replace it.
