Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble bath apparatus which circulates water by a pump to generate a large bubble jet and a fine bubble jet in a bath.

[0002]

2. Description of the Related Art Conventionally, as a foam bath device of this type, there has been a structure as shown in Japanese Utility Model Publication No. 2-12522. The configuration will be described below with reference to FIG.

The hot water in the bathtub 1 is sucked by the water pump 2 and ejected from the flow path outlet 3 into the bathtub 1. At this time, the amount of ejected air is adjusted by the air suction mechanism. This allows
A bubbly water flow is ejected from the flow path outlet 3. On the other hand, in order to raise the temperature of the hot water inside the bathtub 1, the hot water in the bathtub 1 is caused to flow through the heating channel 5 and heated by the gas burner 6.

[0004]

However, in the above-mentioned conventional configuration, the bubbly water flow ejected from the flow path outlet 3 is 3 to 3.
There was a problem that there was no function to change the bubble diameter with only 5 mm bubbles. In addition, since there is only one type of air bubble, there was some unsatisfactory commercial product.

Further, there is no function of filling the bathtub 1 with water, which is not always sufficient in terms of usability.

The present invention is to solve the above-mentioned problems, and a single jet nozzle produces a large bubble of 3 to 5 mm and several tens of μm.
It is an object of the present invention to provide a bubble bath device which has a function of generating fine bubbles and automatically fills a bath.

[0007]

In order to achieve the above object, the present invention has a bath, a bath heat exchanger for heating water in the bath, a bubble ejecting means provided in the bath, and a bath. A circulation circuit configured to connect the heat exchanger and the bubble ejecting means so as to circulate the water in the bath, a circulation pump arranged in the circulation circuit, and one end of which is connected to the circulation circuit and the other end. Is a hot water supply pipe connected to the outlet side of the hot water heat exchanger, and the bubble jetting means comprises first flow path area varying means for changing the flow velocity of the circulating water delivered from the circulation pump, and 1. A mixing section which is provided downstream of the flow path area varying means for mixing the circulating water and the air, and a mixed flow which is provided downstream of the mixing section and in which the circulating water is mixed with air are passed to further change the flow velocity. A second flow path area varying means having a porous body; In which a control means for controlling the flow area varying means and said second flow path area varying means.

[0008]

According to the present invention, with the above structure, the water flow speeded up by the first flow passage area varying means is mixed with air to form a mixed flow, and this mixed flow is provided in the second flow passage area varying means. Collides with the formed porous body. Then, when passing through the fine pores, the bubbles in the mixed flow are further miniaturized and become milky white and discharged into the bath. In addition, the hot water discharged from the heat exchanger for hot water supply is caused to flow into the circulation circuit via the hot water supply pipe to automatically fill the bath.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1 to FIG. 3, 7 is a bath heat exchanger, and the bath heat exchanger 7 and the bubble jetting means 9 provided in the bath 8 are provided by a circulation circuit 12 consisting of a forward pipe 10 and a return pipe 11. It is plumbed. A circulation pump 13 is provided in the return pipe 11. A hot water supply pipe 16 is connected to the discharge side of the circulation pump 13 from the outlet side of the hot water supply heat exchanger 14 via an electromagnetic valve 15. The structure of the bubble jetting means 9 provided in the bath 8 will be described. A jet nozzle 17 is provided downstream of the outflow pipe 10.

It is composed of. The first flow passage area varying means 18 is a first switching valve 22 in which a first flow passage 20 formed of a large diameter through hole and a second flow passage 21 formed of a small diameter through hole are provided orthogonal to each other. It is configured. Further, the air supply means 19 includes solenoid valves 23, 24 for controlling the flow rate of air, and the solenoid valve 2.
3 and 24, and an air pipe 25 for sending the air to the downstream of the first flow path area varying means 18. Reference numeral 26 is a mixing portion where the water flow and the air flow are mixed. Reference numeral 27 denotes a second flow path area varying means, which is a first flow path 28 formed of a through hole and a second flow path 30 provided with a wire net 29 which is a pore body and provided orthogonally to each other. It is composed of two switching valves 31. First switching valve 22
The second switching valve 31 is configured to be switched by the drive motor 32 via the interlocking mechanism 33. 34
Is a mixing nozzle, and 35 is a suction port from the bath 8. An operation panel 36 sets the hot water temperature and hot water amount. 37 is a controller, which is the operation panel 3
By operating a bubble changeover switch (not shown) of 6, the circulation pump 13, the solenoid valve 15, the air control valves 23 and 24, the drive motor 32, etc. are controlled. 38 is Karan, 3
9 is an arrow indicating the flow of water, and 40 and 41 are bubbles.

Next, the operation of the above configuration will be described. First, the automatic filling operation of the bath will be described with reference to FIG. 1. When the amount of hot water supplied to the bath 8 and the hot water supply temperature are set by the operation panel 36 and an operation switch (not shown) is turned on, the solenoid valve 15 is opened. The hot water discharged from the hot water heat exchanger 14 is
It flows through the circulation circuit 12 and is supplied to the bath 8 from the bubble jetting means 9. When the supply amount reaches the set value on the operation panel 36,
The solenoid valve 15 is closed and the automatic filling is completed.

Next, the operation when a large bubble of 3 to 5 mm is generated will be described with reference to FIGS. At this time, when the bubble switch (not shown) of the operation panel 36 is turned on, the circulation pump 13 is operated, and the hot water discharged from the circulation pump 13 is ejected from the ejection nozzle 17. The jetted jet shears the air flowing into the air pipe 25 via the air control valve 23 and jets it into the bath 8 as bubbles of 3 to 5 mm. At this time, the first switching valve 22 is a first through valve having a large diameter through hole.
Is on the flow path 20 side, and the second switching valve 31 is on the through hole 28 side, and a jet flow including bubbles is jetted to the bath 8 without resistance.

Next, the operation of generating fine bubbles of several tens of μm will be described with reference to FIGS. 2 and 3. At this time, when a bubble switch (not shown) provided on the operation panel 36 is turned on, the first switching valve 22 and the second switching valve 31 are driven by the drive motor 32 and the rotation is transmitted by the interlocking mechanism 33. The first switching valve 22 is switched to the second passage 21 side of the small-diameter through hole, and the second switching valve 3
1 is switched to the side of the second flow path 30 provided with the wire net 29.
Further, the air control valve 23 is closed and the air control valve 24 is opened. A flow passage restrictor is provided on the air control valve 24 side. When the circulation pump 13 is operated in this state,
From the small-diameter through hole 18, a jet flow is ejected at a higher pressure and at a higher speed than when a bubble of 3 to 5 mm is generated. This high-speed jet shears the air from the air pipe 25 and ejects it as bubbles of about 0.5 mm. The ejected bubbles further collide with the pore body 29. As a result, the bubbles of about 0.5 mm are made into fine bubbles of several tens of μm by the pore body 23. Porous body 29
The bubble diameter becomes smaller as the collision velocity of the jet impinging on the nozzle becomes higher, and fine bubbles can be stably generated. The fine bubbles are ejected from the mixing nozzle 34, and the hot water inside the bath 8 becomes cloudy.

In this embodiment, one type of circulation pump can generate two types of bubbles as described above, which is low in cost.
