DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub with an air bubble generating device having a function of generating air bubbles, and more particularly to a structure used for protecting piping at the bottom of the bathtub.

[0002]

2. Description of the Related Art In general, a bathtub with a bubble generator is provided with an air injection port for injecting air bubbles at the bottom of the bathtub, and an air distribution pipe branched from an air supply pipe for supplying air is provided below the bottom of the bathtub. The distribution pipes are formed so as to communicate with the air injection ports.

[0003]

By the way, the air distribution pipe which is piped to the bottom of the bathtub is made of synthetic resin in consideration of assemblability and the like. However, if a mouse enters the bottom of the bathtub after construction, Rats may bite the air distribution line. The present invention has been made in view of the above problems, and an object of the present invention is to cover the bottom of a bathtub with a lower cover so that the air distribution pipe can be prevented from being bitten by a rat or the like, and furthermore, the air injection It is an object of the present invention to provide a bathtub with an air bubble generator that can receive even if water leaks from a mouth or the like and can drain the water.

[0004]

In order to achieve the above object, the present invention provides a bathtub with a bubble generator provided with an air injection port 2 for injecting air bubbles at the bottom of a bathtub 1 and branching off from an air supply pipe 3 for supplying air. The air distribution pipes 4 are piped below the bottom of the bathtub 1 and the air distribution pipes 4 are respectively connected to the air injection ports 2.
The lower cover 5 is fitted to the bottom of the bathtub 1 so as to cover the air distribution pipe 4, and the lower cover 5 is provided with a drainage portion for draining water accumulated in the lower cover 5. Features.

The drain portion of the lower cover 5 is constituted by a lower cover drain pipe 6, and a bathtub drain pipe 7 for draining water from the bathtub 1 and the lower cover drain pipe 6 are provided in parallel. It is also preferable to have a feature. Further, it is preferable that a drainage pipe is formed so that drainage from the lower cover drainage pipe 6 and drainage from the bathtub drainage pipe 7 are discharged in different systems.

[0006]

By covering the bottom of the bathtub 1 with the lower cover 5, the air distribution pipe 4 can be prevented from being bitten by a mouse or the like. Also, even if water leaks from the air injection port 2, it can be received by the lower cover 5. Further, the water received by the lower cover 5 can be drained to the outside from the drain section. When the drain pipe 6 for the lower cover and the drain pipe 7 for the bathtub are provided in parallel, the drainage treatment can be easily performed. Further, if drainage pipes are formed so that drainage from the lower cover drainage pipe 6 and drainage from the bathtub drainage pipe 7 are discharged in different systems, the drainage from the bathtub 1 can be prevented from flowing back to the lower cover 5. .

[0007]

FIG. 9 shows the entire bathroom, and a floor pan 8 is shown.
A wall panel 10 is erected on the waist wall 9 around the
A ceiling panel 11 is mounted above. The bathtub 1 is installed at an appropriate place on the floor pan 8. An air pump 12 is installed on the ceiling panel 11, and a ceiling air inlet 13 for sucking air in the bathroom is provided on the ceiling panel 11,
The ceiling intake port 13 and the air pump 12 communicate with each other through an intake pipe 14 made of a flexible hose. An air supply pipe 3 is extended from an air outlet of the air pump 12, and the air supply pipe 3 reaches the bottom of the bathtub 1. A silencer 15 is provided in the air supply pipe 3 near the air pump 12.

1, 3, 4, and 5 are provided on the bottom of the bathtub 1.
As shown in FIG. 1, a plurality of air injection ports 2 are provided, and air distribution pipes 4 branched from an air supply pipe 3 are connected to the air injection ports 2, respectively. The air injection port 2 is provided with a perforated plate, and generates air bubbles by supplying air. The air distribution pipe 4 is formed of a synthetic resin such as a urethane resin. An L-shaped bathtub drainage pipe 7 is connected to the bottom from one end of the bathtub 1 so that drainage in the bathtub 1 can be drained through a drainpipe via the bathtub drainage pipe 7.

As shown in FIGS. 6 to 8, the lower cover 5 is integrally formed of a synthetic resin such as an ABS resin in a pan shape fitting to the bottom of the bathtub 1. Notch 1 in lower cover 5
6, a bulging portion 17, a drain port 18, a reinforcing rib 19 and the like are provided. A lower cover 5 is fitted to the bottom of the bathtub 1 as shown in FIGS.
Etc. are covered. The bathtub drainage pipe 7 is inserted into the notch 16, and the air supply pipe 3 along the outer surface of the side wall of the bathtub 1 is inserted into the bulging portion 17. A heat insulating sheet 20 is attached to the outer surface of the bathtub 1 over the entire circumference.
Is attached to the outer surface of the lower cover 5. An L-shaped lower cover drain pipe 6 is attached to a drain port 18 of the lower cover 5. The drain pipe 6 for the lower cover and the drain pipe 7 for the bathtub are provided in parallel, and the drain pipe 6 for the lower cover and the drain pipe 7 for the bathtub are connected to the drain pipe by separate piping systems.

[0010]

According to the present invention, the lower cover is fitted to the bottom of the bathtub so as to cover the air distribution pipe as described above. It can prevent water from leaking from the air injection port, and can receive the water with the lower cover. As a result, the water accumulated in the lower cover can be drained to the outside from the drainage section.

In the invention according to claim 2 of the present invention, the drainage portion of the lower cover is constituted by a drainage pipe for the lower cover, and the drainage pipe for draining the water in the bathtub and the drainage pipe for the lower cover. Are provided in parallel, so that the drain pipe of the bathtub and the drain pipe of the lower cover can be simultaneously constructed in the same direction, and the workability can be improved. Further, in the invention according to claim 3 of the present invention, since the drainage pipe is formed so that the drainage from the lower cover drainage pipe and the drainage from the bathtub drainage pipe are discharged in different systems, the bathtub is formed. Can be prevented from flowing back to the lower cover.
