[0002]

2. Description of the Related Art Conventionally, as bathtubs installed in bathrooms of houses and the like, bathtubs having various configurations and structures have been provided. For example, as one of them, hot water in the bathtub is circulated. There is also known a bubble generation bathtub that generates a bubble jet flow while making it. In this bubble generating bath, a massage effect is obtained by applying a bubble jet generated in the bath to a desired site such as the back or the sole of the foot, and more comfortable bathing is realized.

The function of such a bubble-generating bath is improved so that a more comfortable bath can be obtained. For example, fine bubbles having a diameter of several to several tens of microns are generated, or the upper part of the bath. It is also practiced to provide a water spout to the hot water outlet and drop hot water into the bathtub from the spout. The fine bubbles can cover the whole body of the bather by spreading throughout the hot and cold water in the bathtub, and even with relatively hot water, it is difficult for the heat to be directly transmitted to the bather, and there is little irritation. In addition, flowing hot water from the spout provides a bather with an image of a waterfall, which is effective in enhancing the refreshing feeling and the bathing atmosphere.

FIG. 5 is a perspective view exemplifying a bubble generation bath which is capable of supplying hot water from the water jet outlet along with the bubble jet flow. For example, as shown in Figure 5,
A water supply port (a) for generating a bubble jet is provided on the wall surface of the bath body (a). Bubble injection nozzles (c) are provided on wall surface portions located on both sides of the wall surface portion on which the water supply port (a) is formed, that is, wall surface portions facing the back side and sole side of the bather. The water passage connecting the water supply port (a) and the bubble jet nozzle (c) is formed by a piping system (d), and a pump (o) for generating a bubble jet flow is formed in the piping system (d). ) Is also connected.

Further, on the wall surface of the bathtub body (a) on the same side as the water supply port (a), a water supply port (f) for jetting fine bubbles is provided.
And a fine bubble jetting port (K) are provided, and a pump (K) for generating fine bubble is connected to the water supply port (F) and the fine bubble jetting port (K) via a piping system (K). . Further, the bathtub body (a) is provided with another water supply port (ko) on the wall surface on the same side as the water supply port (a) (f) and the fine bubble jet port (ki). Is connected to a water outlet (SE) provided in a flange portion (SH) at the upper part of the bath body (A) via a piping system (SA) forming a water channel. A circulation pump (SO) is arranged in the middle of this piping system (SA).

[0006]

However, in the conventional high-performance bubble generating bath as shown in FIG. 5, for example, three pumps (for jetting bubbles, fine bubbles and hot water from the upper part of the bath) are used. Equipped with (e), (h), (so), and those pumps (e), (h), (so) are separately installed in the bathtub body (a).
Since the connection is made by using (S), the configuration and structure of the bubble generation bath is complicated. Therefore, there is a problem that the number of parts is large and the cost is high.

When installing the pump, the pump (e)
A space for (h) and (h) is required, and the installation work of them and the piping connection work with the bathtub body (a) are complicated, and the construction is not easy. The present invention has been made in view of the above circumstances, eliminates the drawbacks of the conventional bubble generating bath, and improves the workability,
Space saving and cost reduction can be achieved.
The purpose is to provide a new bubble generating bathtub.

It is connected to the bubble generating device (10) via. In this bubble generator (10), a pipe (8) connected to a bubble injection nozzle (4) is attached to, for example, a flange at a water discharge port (6) provided in a flange portion (5) above a bath body (1). The lower part of the part (5) is branched and connected.

The bubble generating device (10) can be operated by the operation switch (11).
The operation switch (11) can be installed at an appropriate portion of the inner wall of the bathroom. 2 and 3 are a side view and a plan view, respectively, showing an example of the bubble generating device.

For example, in the examples shown in FIGS. 2 and 3, the second water supply port (2) and the bubble jet nozzle (4) of the bath body (1) illustrated in FIG. The water supply port (21) and the second bubble ejection port (22) are provided on substantially the same plane. The second water supply port (21) and the bubble outlet (22) are communicated with each other by a water channel (23), and a bubble generation pump (24) equipped with a motor (not shown) is provided in the water channel (23). ) Is connected. In the bubble generating pump (24), the pump body can be electrically insulated from the motor by an insulating member made of, for example, resin.

The bubble generator (10) has a first fine bubble jet port (3) of the bath body (1) illustrated in FIG.
Corresponding to, the second fine bubble jet port (25) is provided on substantially the same plane as the second water supply port (21) and the bubble jet port (22). And the second water supply port (21)
A water channel (26) is formed between the nozzle and the second fine bubble jet port (25) to connect them. This waterway (2
In the middle of 6), a fine bubble generation pump (27) having no motor is connected.

An air supply pipe (28) for generating fine bubbles is connected to the water passage (26) from the second water supply port (21) to the fine bubble generating pump (27). On the other hand, from the fine bubble generation pump (27) to the second fine bubble jet port (2
An accumulator (29) for gas-liquid separation is connected to the water channel (26) up to 5). An exhaust valve (30) is arranged above the accumulator (29), and the exhaust valve (30) is provided with a drain pipe connection port (31) provided on substantially the same plane as the second water supply port (21). It is connected to the. These exhaust valve (30) and drain pipe connection port (3
1) is for discharging excess fine bubbles when the fine bubble jet is generated.

Then, these bubble generating pumps (24)
Also, the rotary shaft (3
2) (33) is provided. Bubble generation pump (2
The rotating shaft (32) provided in 4) is connected to the motor. Further, the pulleys (3) having teeth (first teeth) formed on their side surfaces are formed on the upper portions of the rotary shafts (32) (33).
4) and (35) are provided, and these pulleys (3
4) The rubber belt (36) having teeth (second teeth) meshing with the teeth of (35) formed on the inner surface of the pulley (34)
It is hung up around (35).

The motor of the bubble generating pump (24) can be rotated in both forward and reverse directions by turning on the power. In addition, the rotary shaft (3) of the bubble generation pump (24)
In 2), a one-way clutch (37) that engages only in one direction of rotation is provided between the pulley (32). Therefore, when operating the bubble generating pump (24), for example, the one-way clutch (37) is not engaged when the motor is rotating forward, and only the bubble generating pump (24) can be moved. In this case, the fine bubble generation pump (27) does not engage the one-way clutch (37), and the pulley (34) provided in the bubble generation pump (24).
Does not work as it does not rotate. Therefore, only the bubble jet flow is generated when the motor of the bubble generation pump (24) is normally rotated.

On the other hand, when the motor of the bubble generating pump (24) is rotated in the reverse direction, the one-way clutch (37) is engaged and the pulley (32) rotates, so that the rotational force thereof is the gum belt (38) and the pulley (35). ) Is transmitted to the fine bubble generation pump (27) to generate fine bubbles. Such bubble generating pump (24)
The power transmission means for rotating the motor is not limited to, for example, the pulleys (34) and (35) and the rubber belt (36), but may be a gear or the like.

That is, it is possible to keep the number of rotations of the bubble generating pump (24) and the fine bubble generating pump (27) constant at either frequency. Conventionally, it is 50
Although different frequencies of Hz and 60 Hz have been dealt with by adjusting the pressure, this system inevitably reduces the ability of the fine bubble generation pump (27) to generate a fine bubble jet. However, as described above, if the number of teeth of the pulleys (34) (35) is appropriately selected, a constant rotation speed can always be obtained regardless of the difference in frequency, and the ability of the fine bubble generation pump (27) can be obtained. The decrease can be prevented.

For example, in the bubble generation bath having the above configuration, when generating a bubble jet flow, when the bubble jet flow is selected by the operation switch (11) illustrated in FIG. 1, the bubble generation pump (provided in the bubble generation device (10) ( Only 24) operates as described above, and hot water is taken in through the second water supply port (21) from the first water supply port (2) of the bathtub body (1) through the pipe (7), and the bubble generating device (10) is introduced. A bubble jet can be jetted from the bubble jet nozzle (4) into the bath body (1) through the water passage (23), the second bubble jet outlet (22) and the pipe (9).

On the other hand, in the case of generating a fine bubble jet, when the fine bubble jet is selected by the operation switch (11) illustrated in FIG. 1 in the same manner, the bubble generating pump (2
The motor provided in 4) rotates in the direction opposite to the direction in which bubbles are generated, and the rotational force thereof causes the one-way clutch (37), pulley (34), rubber belt (36) and pulley (3).
5) is transmitted to the fine bubble generation pump (27) via
Only this fine bubble generating pump (27) operates. Then, hot water from the bathtub body (1) is taken in through the first water supply port (2) and the pipe (7) from the second water supply port (21) of the bubble generating device (10), and is guided to the water channel (26). Is mixed with air to form fine bubbles, and a fine bubble jet is introduced into the bath body (1) from the first fine bubble jet (3) through the second fine bubble jet (25) and the pipe (8). Can be ejected.

When hot water is poured into the bathtub body (1) from the water discharge port (6) provided in the flange portion (5) on the upper part of the bathtub body (1) illustrated in FIG. 1, the operation switch (11) is used. ), The bubble generating device (10) operates in the same manner as when the bubble is generated, but the electric valve (38) illustrated in FIG. 4 is switched, and the pipe (9) communicates with the outlet (6). Then, the hot and cold water in the bathtub body (1) is circulated by the bubble generating pump (24) and is made to flow into the bathtub body (1) through the water discharge port (6).

Thus, in the bubble generator (10),
The conventional bubble generation pump and the fine bubble pump are integrated. In addition, these pumps are replaced by a bubble generation pump (2
The pumps (24) and (27) are selectively used by operating one motor provided in 4) and by rotating the motor forward and backward. Further, the circulation pump for supplying hot water from the water discharge port (6) at the upper part of the bathtub body (1) is omitted, and the bubble generation pump (24) is used instead. The flow of hot water from the water discharge port (6) is caused by the bubble jet flow. The supply pipe (9) is branched, and the flow path is switched by an electric valve (38) provided at the branch portion.

Therefore, the bubble generator (10) is simplified and can be made compact. The space for installing the pump is reduced and the space for installing the bubble generating bath is reduced. In addition, the bathtub body (1) and the bubble generator (10) are both one water inlet (2) (21).
Therefore, the piping system is also simplified with the simplification of the bubble generator (10).

Therefore, the workability of the bubble generating bath is improved,
Since the number of parts is also reduced compared to the conventional bubble generation bath, manufacturing is simplified and cost can be reduced. Of course, the present invention is not limited to the above examples. It goes without saying that various aspects are possible in details such as the structure and configuration of the bathtub body and the pump structure.
