DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bubble water flow generator for generating a large bubble jet and a fine bubble jet by switching water in a water tank by circulating water with a pump.

[0002]

2. Description of the Related Art Conventionally, as this type of bubble water flow generator, there has been a device as shown in Japanese Patent Application Laid-Open No. Hei 1-230358. Hereinafter, the configuration will be described with reference to FIG.

The hot water 2 in the bathtub 1 is sucked from a suction pipe 4 provided on the suction side of the pump 3, and is discharged from the discharge pipe 5 to the bathtub 1. In the suction side pipe line 4, a rapidly reducing flow path 6 is formed. When the pump 3 is operated to emit a large bubble jet, the hot water 2 is sucked from the suction port 7 and jetted from the low-pressure jet nozzle 8 into the bathtub 1 as a large flow large bubble jet. On the other hand, in the case of emitting fine bubbles, when the two-way valve 9 is opened and closed and the pump 3 is operated, the hot water 2 is sucked and discharged from the suction port 7. As a result, the pressure of the discharge side pipeline 5 increases,
When a certain pressure is reached, the pressure is transmitted through the branch circuit 10 and the air insertion valve 11 is opened. As a result, the atmosphere is sucked from the air insertion valve 11 through the air passage 12 into the rapid reduction channel 6. The sucked air is dissolved in the hot water on the discharge side of the high-pressure pump. The hot water 2 in which the air is dissolved is supplied to a high-pressure blowing valve 13 provided in the bathtub 1.
Are blown out as fine white bubbles.

[0004]

However, in the conventional configuration, a large-sized, high-priced pump having a large shutoff head and a large flow rate is always operated at the maximum capacity, and the power consumption is large. This is because, in order to generate a large bubble jet, it is necessary to flow a large flow rate in a state where there is the rapidly reducing flow path 6. In addition, when generating fine bubbles, it is necessary to increase the pressure to about 5 kg / cm ² in order to dissolve air in warm water, and to obtain this high pressure, a pump with a low flow rate and a large shutoff head is required. A large pump was required to satisfy this condition.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide a bubble water flow generating apparatus which generates a large bubble jet and a fine bubble jet with a low-cost pump having a small shutoff head and low power consumption.

[0006]

In order to solve the above-mentioned problems, a bubble water flow generating device according to the present invention comprises: a circulating pump capable of switching the capacity of circulating water in a water tank; and a suction side of the water tank and the circulating pump. A suction circuit that communicates, a discharge circuit that communicates the discharge side of the circulation pump with the water tank,
The discharge circuit is provided with a bubble ejecting means that can switch between a large bubble jet and a fine bubble jet. When the large bubble jet is used, the capacity of the circulation pump is reduced, and when the fine bubble jet is used, the capacity of the circulation pump is increased. Switching is performed in correspondence with each other.

[0007]

According to the present invention, the circulating pump does not always operate at the maximum capacity due to the above-mentioned structure. The pump capacity is switched according to the time of large bubble jet and fine bubble jet.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3, reference numeral 14 denotes a water tank,
A suction circuit 16 is provided from the water tank 14 to a circulation pump 15, and a discharge circuit 18 is provided from the circulation pump 15 to a bubble blowing means 17 provided in the water tank 14. The bubble jetting means 17 is a jet nozzle 1 for jetting water.
9 and an air supply means 20 provided downstream of the ejection nozzle 19. The air supply means 20 includes an air pump 21 and solenoid valves 22, 23, 24 for controlling the flow rate of the air pump 21.
And an air pipe 25 for sending air controlled by the solenoid valves 22, 23, 24 downstream of the ejection nozzle 19. Reference numeral 26 denotes a mixing section where the water stream and the air stream are mixed. Numeral 27 designates a variable flow path area, which comprises a switching valve 28 and a drive motor 29. Switching valve 2
8, a first flow path 30 and a second flow path 31 are provided orthogonal to each other. The first flow path 30 has a penetrating configuration, and the second flow path 31 is provided with a wire mesh 32 which is a porous body. Reference numeral 33 denotes a controller, which receives a signal from an operation switch 34 to control the air pump 21, the solenoid valve 22,
23, 24, the drive motor 29, and the circulation pump 15 are controlled. An arrow 35 indicates the flow of water, and an arrow 36 indicates a bubble.

Next, the operation of the above configuration will be described.
First, a description will be given of the time when fine bubbles are generated with reference to FIGS. At the time of generation of microbubbles, the flow area variable means 27 is driven by the drive motor 29, and the switching valve 28 is on the second flow path 31 side having the wire mesh 32. This wire mesh 32 has 100
A plurality of mesh-sized ones are provided. In this state, the air sent from the air pump 21 is ejected from the air pipe 25 via the electromagnetic valve 22 having the smallest flow passage area. The amount of air at this time is about 100 cc per minute.
The air ejected from the air pipe 25 is supplied to the ejection nozzle 19.
However, a wire mesh 32 is provided downstream of the air pipe 25, and the bubbles and the water stream of about 0.5 mm collide with the wire mesh 32, thereby causing bubbles of about 0.5 mm. Finely divided into bubbles of .06 mm. The micronized bubbles become milky white and are discharged to the water tank 14. In such an operation, the circulation pump 15 is operated with a large capacity by a signal from the controller 33. That is, the flow rate from the ejection nozzle 19 is increased to increase the flow velocity, the energy for colliding with the wire mesh 32 is increased, and the performance of generating fine bubbles is enhanced.

Next, the operation when a large bubble is generated is shown in FIG.
And FIG. When the small or large operation switch 29 is pressed, the drive motor 29 operates and the switching valve 28
Rotates. At this time, the switching valve 28 rotates 90 degrees and stops. Therefore, the first flow path 30 faces the ejection nozzle 19. The air ejected from the air pipe 25 is released into the water tank 14 as large bubbles of several mm due to the shearing force of the water flow from the ejection nozzle 19. At this time, the first flow passage 30 is operated in a state where the capacity of the circulation pump 15 is reduced because the flow passage resistance is small because the first flow passage 30 has a low flow passage resistance.

[0012]

As described above, the bubble water flow generating device of the present invention comprises a water tank, a circulating pump capable of switching the capacity of circulating water in the water tank, a suction circuit communicating the water tank with the suction side of the circulation pump, and a circulation circuit. Equipped with a discharge circuit that connects the discharge side of the pump to the water tank, and a bubble discharge means that is provided in the discharge circuit and that can switch between large bubble jets and fine bubble jets. By switching the capacity of the circulating pump in such a manner and operating the circulating pump in a state of reduced capacity during large bubble jet, the power consumption is reduced.
