2. Description of the Related Art Conventionally, bathtubs having various structures and structures have been provided as bathtubs installed in bathrooms of houses and the like. For example, as shown in the perspective view of FIG. 4, there is known a bubble generation bathtub capable of generating a bubble jet and a fine bubble jet while circulating bath water in a bathtub (A).

In this bubble generating bath, the pump unit (a) is operated to take out bath water from a water supply port (c) provided in the wall portion of the bath tub (a), and the bath water is supplied to a bubble jet nozzle (d). It can be sent, mixed with air bubbles and injected into the bathtub (A). A massage effect can be obtained by applying such a bubble jet to a desired site such as the back and soles.

The bubble generating bath shown in FIG. 4 is provided with a system for generating a fine bubble jet. Activate the pump unit (a) and dissolve air in the pump unit (a) into the bath water taken out from the water supply port (c) of the bathtub (a) to make fine bubbles. Supply from (e) into bathtub (a). The fine bubbles are
By spreading over the bathtub (a), the bather's entire body is wrapped, and even if the water is relatively hot, the heat is not directly transmitted to the bather, and there is an effect that there is little stimulation.

[0005] In a bubble generating bath which realizes both the bubble bath and the fine bubble bath, a strainer for removing dust and the like in the bath water is provided in the middle of the flow path of the fine bubble jet. The strainer can be shown, for example, in the perspective view of FIG. 5, and a Y-shaped strainer (f) is widely used. The bath water sucked from the water supply port (c) of the bathtub (a) shown in FIG. 4 passes through the Y-shaped strainer (f) so as to slightly bypass in the middle of the flow path of the fine bubble jet. The strainer (f) is provided with a filter (key) such as a wire mesh. When the bath water passes through the filter (key), dust or the like contained in the filter is removed by the filter (key).

[0006]

However, for example, a conventional Y-shaped strainer (f) as shown in FIG.
In the case of (1), the filter (g) is clogged by dust or the like, so that periodic maintenance is required. The Y-shaped strainer (f) is provided with a cap (h).
The cap (h) was removed, and the filter (h) had to be taken out from the inside and cleaned.

Further, when the filter (g) is clogged, the suction pressure loss of the air (g) taken in from the air suction pipe (g) increases. For this reason, there is a problem that the discharge pressure of the fine bubble jet is reduced due to an increase in the amount of air, the diameter of the fine bubble increases, and the quality of the fine bubble jet becomes unstable. The present invention has been made in view of the above circumstances, and has been developed in a conventional bubble generating bath .
That eliminates the drawbacks of the strainer, while improving the maintainability of the cleaning of the filter provided in the minute bubbles channel as a convenient and easily, can also be achieved to stabilize the quality of the fine-bubble jets, improved It is an object of the present invention to provide a bubble-generating bath tank.

[0008]

Means for Solving the Problems] The present invention, as to solve the above problems, in the bubble generating bath for generating fine bubbles jets with bubble jets, in the middle of the flow path of the bubble jet bath water flow bubbles The bubble generation bath is characterized in that the flow path of the fine bubble jet smaller than the flow path of the jet is connected via a strainer, and the strainer is provided with a filter facing the flow path of the bubble jet. A tank is provided.

[0009]

[Action] Oite the bubble generating bath tub of the invention, the middle of the flow path of the bubble jet bath water flow rate is less than the flow passage of the bubble jet
Together have connecting flow path of the micro-bubbles jet by interposing a strainer, the strainer is arranged a filter facing the flow path of the bubble jet. When the bubble generation bath is operated in the mode of generating fine bubbles and then switched to the mode of generating bubbles, the bath water flowing in the flow path of the bubble jet has a considerably larger flow rate than when flowing in the flow path of the fine bubble jet. Therefore, dust and the like trapped in the filter of the strainer are drawn into the flow and removed from the filter. For this reason, the trouble of removing and cleaning the filter from the strainer is omitted, and the maintenance is greatly simplified. Also, since clogging of the filter is reduced,
The air suction amount is stable, and the quality of the fine bubble jet is kept good.

EXAMPLES Hereinafter, Examples with reference to the drawings, will be described in more detail with the air bubble generating bath tub of the present invention. FIG.
Is a fragmentary cross-sectional view showing one embodiment of the bubble generating bath tub of the present invention.

For example, in the example shown in FIG.
In the middle of the flow path (2) of the bubble jet from the bathtub body to the bubble generation pump (1), the flow rate of the bath water is smaller than the flow path of the bubble jet so as to be substantially orthogonal to the flow path (2). A flow path (3) for a bubble jet is arranged. A strainer (4) is provided between the flow paths (2) and (3) of the bubble jet and the fine bubble jet, and are connected so that the flow paths (2) and (3) communicate with each other. At the connection between the strainer (4) and the channels (2) and (3), a water sealing means (5) such as an O-ring is interposed to prevent the occurrence of water leakage.

Further, the strainer (4) is provided with a filter (6) facing the flow path (2) of the bubble jet. For example, a wire mesh or the like can be used as the filter (6). There is no particular limitation on the material. There is no particular limitation on the size of the mesh. In this example, the filter (6) is expanded in a substantially spherical shape on the side of the flow path (3) of the fine bubble jet, thereby increasing the filter area.

FIG. 2 is a partially cutaway side view illustrating the flow path of the fine bubble jet connected to the strainer. The flow path (3) of the fine bubble jet is connected to a fine bubble generation pump, and an air suction pipe (7) is connected in the middle of the flow path. FIG.
As shown in the enlarged cross section of the strainer (4), the strainer (4) is provided with a negative pressure generator (8) on the side of the flow path (3) of the fine bubble jet. The diameter of the opening of the strainer (4) in the negative pressure generating section (8) is reduced, so that a negative pressure can be generated in the flow path (3) of the fine bubble jet, and the air shown in FIG. This allows air to be effectively taken into the flow path (3) from the suction pipe (7).

For example, in the strainer structure described above, when the bubble generating pump (1) operates, the bath water taken out of the bathtub body flows only through the bubble jet flow path (2), and the bubble generating pump ( It is sent out to the bathtub body through another flow path (9) connected to the bubble jet nozzle via 1). This is the bubble generation mode of the bubble generation bath.

On the other hand, when the fine bubble generating pump connected to the fine bubble jet flow path (3) is operated, the bath water in the bathtub main body passes through the bubble jet flow path (2), and the strainer (4).
Flows through the flow path (3) of the fine bubble jet. At this time, dust and the like contained in the bath water are captured by the filter (6) of the strainer (4) provided facing the flow path (2) of the bubble jet, and are accumulated on the surface of the filter (6). This is the fine bubble generation mode.

However, when the operation mode of the bubble generating bath is switched to the bubble generating mode and the bubble generating pump (1) is operated, the flow rate of the bath water flowing through the bubble jet flow path (2) in this mode becomes small. Since the flow rate of the bath water flowing through the flow path (3) of the fine bubble jet in the generation mode is considerably larger, the dust and the like trapped in the filter (6) are removed from the bath water flowing through the flow path (2) of the bubble jet. And is removed from the filter (6). Normally, the flow rate of the bath water flowing in the bubble jet flow path (2) in the bubble generation mode is set to about 15 times the flow rate of the bath water flowing in the fine bubble jet flow path (3) in the fine bubble generation mode. Have been. For this reason, the trouble of removing and cleaning the filter (6) from the strainer (4) can be omitted, and the filter (6) can be operated only in the bubble generation mode.
Can be cleaned. Manual maintenance is greatly simplified, and is extremely simple and easy. If maintenance is required, the period will be much longer than before.

Also, since the clogging of the filter (6) is considerably reduced, the air suction pressure loss is reduced, and the amount of air suctioned from the air suction pipe (7) shown in FIG. 2 is stabilized. The quality of the fine bubble jet is kept good, and an effective fine bubble bath can be maintained. Of course, the present invention is not limited by the above examples. It goes without saying that various aspects are possible for the details such as the configuration and structure of the bubble generating bath and the material of the filter.

[0018]

As described in detail above, according to the present invention, the cleaning of the filter provided in the microbubble flow path becomes simple and easy, and the maintainability is improved. The maintenance period can be greatly extended. Further, the quality of the fine bubble jet can be stabilized, and an effective fine bubble bath is maintained.
