Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble generating bath.

[0002]

2. Description of the Related Art Conventionally, for example, actual Kaihei 1-177584.
As described in Japanese Patent Publication, etc., a bubble generating nozzle is provided in the bathtub, and air is generated from the air supply pipe to the bubble generating nozzle to generate bubbles in the hot water in the bathtub and massage the bather. A bubble generating bathtub that provides effects and the like is known.

In such a bubble generating bath, water tends to collect in the air supply pipe, and when water accumulates in the air supply pipe, the air supply pipe may be rusted or frozen in a cold region to block the air supply pipe. Make or destroy. In order to remove such residual water in the air pipe, various measures have been conventionally made.

For example, as described in Japanese Utility Model Laid-Open No. 1-177585, the opening of the drain plug of the bathtub is detected, and the air pump is operated for a certain time based on the detection result to remove the residual water in the air supply pipe. It is known to do so.

[0005]

However, as described in Japanese Utility Model Laid-Open No. 1-177585, the opening of the drain plug of the bathtub is detected, and the air pump is operated for a certain period of time based on the detection result. In the case of removing the residual water, a detection device is required, and the air pump needs to be operated during drainage, so that the operating cost of the air pump is not stupid.

The present invention has been made by paying attention to the problems in the conventional bubble-generating bath, and the purpose thereof is to solve the problems in the conventional bubble-generating bath and to provide a special solution. An object of the present invention is to provide a bubble generating bath which does not require a detection device or the like, nor does it require an air pump to operate during drainage, and which has a simple structure for removing residual water in an air supply pipe.

[0007]

In order to achieve the above object, the bubble generating bath of the present invention is provided with a bubble generating nozzle, and bubbles are generated by supplying air from an air supply pipe to the bubble generating nozzle. In the bubble generation bathtub made in this way, one end of the air supply pipe is connected and opened in the middle of the drainage pipe of the bathtub, and a drain plug is provided on the downstream side of the connection opening of the air supply pipe of the drainage pipe. A drain is provided with a lid, and the lid is connected to the drain plug by a connector.

In the present invention, the connecting body for connecting the lid and the drain plug is not particularly limited, but a metal or synthetic resin chain or string having high water resistance can be used. .

[0009]

In the bubble generating bath according to the present invention, one end of the air supply pipe is connected and opened at a middle portion of the drain pipe of the bath, and a drain plug is provided downstream of the connection opening of the air supply pipe of the drain pipe. Since the drain is connected to the drain pipe, the lid is provided, and the lid is connected with the drain plug by the connector, so that the drain plug can be removed at the same time by removing the lid when draining the bathtub. At the same time as the drainage of water, the water in the air supply pipe can be discharged from the drain pipe.

[0010]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a schematic explanatory view showing an example of the bubble generating bath of the present invention, and FIG. 2 is an enlarged sectional view of a main part of the bubble generating bath of the present invention shown in FIG.

In these figures, 1 is a bathtub, 2 and 2,
.. is an air bubble generating nozzle provided on the bottom wall 11 of the bathtub 3, 3 is an air supply pipe for supplying air to each of the bubble generating nozzles 2, 2, ..., The base end portion is connected to the air pump 4. Has been done.

Reference numeral 5 denotes a drain pipe, and the upper end of the drain pipe 5 is connected to the drain port 12 of the bath 1. A female screw is engraved in the drainage port 12, and the lid body 6 is screwed into this female screw.

The tip of the air supply pipe 3 is connected and opened in the middle of the drainage pipe 5, and the air supply pipe 3 has a gradual downward slope from the base end to the front end, and the water in the air supply pipe 3 is gradually inclined. Flows into the drain pipe 5. A drain plug 7 is provided on the downstream side below the connection opening of the drain pipe 5 with the air supply pipe 3, and the drain plug 7 and the lid 6 are connected by a stainless steel chain 8.

[Operation of Embodiment] Next, the operation of the bubble generating bath according to the present invention shown in FIGS. When the drainage port 12 of the bathtub 1 is provided with the lid body 6 and the drainage pipe 5 is provided with the drainage plug 7 and hot water is stored in the bathtub 1,
Air from the air pump 4 is sent to each of the bubble generating nozzles 2, 2, ... Via the air supply pipe 3 to generate bubbles.

When the hot water in the bathtub 1 is drained after bathing, if the lid 6 is removed from the drainage port 12 of the bathtub 1, the drain plug 7 is also removed at the same time, and the hot water in the bathtub 1 is drained from the drain pipe 5. .

At this time, the water in the air supply pipe 3 flows into the drain pipe 5 and is drained from the drain pipe 5. Again, when hot water is stored in the bathtub 1, the lid 6 is screwed into the drainage port 12 of the bathtub 1, so that the drain plug 7 is also applied to the drain pipe 5, and the drain pipe 5 is closed.

Although the embodiment of the present invention has been described above with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and changes in design within the scope not departing from the gist of the present invention can be made. Even if it exists, it is included in the present invention. For example, in the illustrated embodiment, the nozzle of the present invention is provided on the bottom wall of the bathtub, but it may be provided on the side wall of the bathtub or the like. or,
You may use the fumarolic plate with which the fumarole was bored for the lid body.

[0018]

In the bubble generating bath according to the present invention, the drain plug can be removed at the same time by removing the lid when draining the bath, and the water in the air supply pipe can be drained from the drain pipe at the same time as the drain of the bath. Therefore, unlike the conventional bathtub, it is not necessary to individually operate the detection device or the air pump, and the water in the air supply pipe can be discharged with a simple structure.
