DESCRIPTION OF THE PREFERRED EMBODIMENTS The contents of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a schematic view showing a main part of a circulating bath equipped with a fine bubble generating mechanism according to the present invention. One mounting hole 1 is drilled in the side wall of the bathtub B, and a hot water inlet 21 is provided there.
Downward fine air bubble outlet 22 and upward hot water outlet 2
Nozzle 2 provided with 3 is attached in a watertight manner,
The heating circulation circuit 3 and the fine bubble generation circuit 4 are connected to the nozzle 2. The hot water inlet 21 is drawn from the peripheral edges of the outlets 22 and 23 toward the heating circulation circuit 3.

The heating circulation circuit 3 is a hot water inlet 2 of the nozzle 2.
A circulation pipe 31 is connected between the hot water discharge port 1 and the hot water discharge port 23, and the heater 5, the filtration tank 6, the circulation pump 7, the activation tank 8 and the heater 5 are passed in the middle, and finally the flow rate switching valve. 9 are sequentially connected, and the filtration tank 6 and the circulation pump 7 are connected.
Ozone generator 11 equipped with an air intake solenoid valve 10 between
Thus, ozone air is injected into the circulation pipe 31. The heater 5 has a structure shown in FIG. 2, and a heater 51 formed by molding a nichrome wire is passed through a heat exchanger 52 made of aluminum die cast, and the heat exchanger 52 has a circulation pipe 31a made of stainless steel. The hot water circulates between 35 and 40 degrees after heat exchange.
Set it so that it becomes a degree. The reason why the circulation pipe 31a is passed twice is to exchange heat without waste. The heater 5 can employ an appropriate means such as a gas combustion heater or an electric heater using zirconia-based ceramic.

The filtration tank 6 is constructed such that a sponge-like filter cloth 61 made of polyurethane or the like has a plurality of layers inside, and the filter cloth 61 physically captures human hair, dirt, hair, dust and the like and filters it. Pipe 6 with the hot and cold water
2 is discharged downward. Ozone air is supplied to the circulating hot water by the ozone generator 11 connected to the circulation pipe 31 between the filtration tank 6 and the circulation pump 7 to sterilize various bacteria in the filtered hot water, decompose fat and the like, and deodorize. In the illustrated example, the ozone generator 11 is used for sterilization. However, an ultraviolet sterilizer may be used, and the sterilization treatment may be performed at an appropriate point of the heating circulation circuit 3. You may make it arrange | position in the location etc. near the hot water inlet 21.

The activation tank 8 contains barley stone, sulfur stone,
The active stones 81 such as obsidian, rhyolite, and unweathered pearlite are mixed in one kind or two or more kinds and are filled in the net 82 for the convenience of handling. Hot water is introduced from the lower part and discharged from the upper part. The hot water introduced in this manner is in even contact with the activated stone 81. In the activation tank 8, the bacteria generated on the surface of the stone are biologically purified, and organic substances such as ammonia are decomposed and biologically purified. At the same time, active ingredients such as iron, magnesium, calcium, sodium, and zinc are dissolved in hot water, and the hydrogen ion concentration is neutralized to a neutral degree, so that inorganic chemical treatment is performed.

In the illustrated example, the flow rate switching valve 9 is a valve body 91.
A valve chamber 93 orthogonal to a flow passage 92 connected to the circulation pipe 31 inside is provided, and a diaphragm 94 is provided on the flow passage 92 side of the valve chamber 93.
And the flow path 92 is provided with an orifice 95, and the flow reduction plate 9 is provided with a side to which the diaphragm 94 adheres.
6 is fitted, and the branch pipe 97 from before the fine bubble orifice 14 of the circulation pipe 31 forming the heating circulation circuit 3 is connected to the valve chamber 93. Therefore, when only the heating circulation circuit 3 is operated, the orifice 95, the diaphragm 94, and the flow reduction plate 96.
Although it will be jetted from the gap to the hot water discharge port 23, when the fine bubble generating circuit 4 is operated, the hot water reaches the valve chamber 93 from the branch pipe 97 and presses the diaphragm 94 to reduce the flow reduction plate 96.
It comes into close contact with the side of the above and is discharged from the orifice 95 only to the bath B, so that the flow passage 92 is narrowed. By using the flow rate switching valve 9 having such a configuration, it is possible to reduce the amount of hot water without stopping the heating circulation circuit 3 and prevent the fine bubbles supplied at the same time from being stirred and disappearing. The use of the flow rate switching valve 9 having such a structure has the advantages that the structure is simple and durable, the operation is reliable, and the repair is easy. However, a conventionally used solenoid valve may be used.

As described above, the hot water maintained by the heater 5 and circulated by the circulation pump 7 is completely treated by the physical treatment by the filtration tank 6, the sterilization treatment by the ozone generator 11, and the biological treatment by the activation tank 8. It will be cleaned. The hot and cold water treated in this way passes through the flow rate switching valve 9,
It is returned to the bathtub B from the hot water outlet 23.

The fine bubble generating circuit 4 is constructed such that a circulation pipe 41 is connected to the outlet of the filtration tank 6 of the heating circulation circuit 3 and is connected to the fine bubble discharge port 22. A bubble pump 12, an air separation tank 13, and a fine bubble orifice 14 are interposed, an air intake solenoid valve 15 is connected in front of the fine bubble pump 12, and air that has not dissolved in the air separation tank 13 is connected. A return pipe 16 is provided so as to supply the fine bubble to the fine bubble pump 12 again. By branching from the filtration tank 6, it is possible to prevent dust and human hair from entering the fine bubble generation circuit 4 and causing a failure.

When hot water is sucked by the fine bubble pump 12, the air intake solenoid valve 15 is opened so that the air is entrained and sucked in the circulation pipe 41, and the fine air bubble is mixed with the air. It reaches the pump 12 and is pressurized inside the pump 12, and this pressurization causes air to be dissolved in the hot and cold water. By passing through the fine bubble orifice 14, the pressure is released at once from the pressurized state and the orifice causes The air that has been dissolved in the hot and cold water is released due to the change in the flow velocity due to the increase in the flow velocity, etc., and fine air bubbles are generated by this air. The fine bubbles have a diameter of about 10 μm and are very fine, so that the floating speed is slow and they stay in the hot and cold water of the bathtub for several minutes to dye the hot and cold water in milky white.

An air separation tank 13 is provided between the fine bubble pump 12 and the fine bubble orifice 14 to separate excess air that has not been melted, and is returned to the fine bubble generating circuit 4 to supply a new air and a fine bubble pump. 12 is supplied. If this air separation tank 13 is not provided, large bubbles will be discharged from the fine bubble discharge port 22. Note that the surplus air may be directly discharged to the atmosphere. These fine air bubbles wrap around the surface of the bather's body, lowering the sensible temperature of hot water by several degrees below the actual temperature, not only suppressing the rise in blood pressure during bathing, but also the dirt adhering to the surface of the body. It will envelop and remove dirt. Reference numerals 17 and 17 are check valves provided in the heating circulation circuit 3 and the fine bubble generation circuit 4.

Since the heating circulation circuit 3 maintains the purifying action and temperature of the hot water, it may be operated continuously for 24 hours, but at night when there is no possibility of bathing,
It may be operated intermittently by detecting the temperature of hot water (not shown). Immediately before or during bathing, the fine bubble generation circuit 4 is operated, and at the same time, the flow rate switching valve 9 squeezes the hot water circulating in the hot water of the bath by the heating circulation circuit 3 to heat and circulate the hot water sucked from the suction port 21. The liquid is suitably distributed to each of the circuit 3 and the fine bubble generation circuit 4, so that the amount of hot water from the hot water discharge port 23 is reduced and the residence time of the fine bubbles in the bath is extended. Also, by changing the discharge direction by setting the fine bubble discharge port 22 downward and the hot water discharge port 23 upward, the residence time of the fine bubbles can be further extended. An electric flow rate switching valve (not shown) may be provided near the hot water discharge port 23 of the heating circulation circuit 3 to reduce the flow rate when the fine bubble pump 12 is operated. It can be said that such a configuration is excellent not only in that the number of parts is reduced and the configuration is simple, but also that the operation is reliable.

FIG. 3 shows another embodiment, which has the same configuration except that the circulation pipe 41 forming the fine bubble generating circuit 4 is branched from between the hot water inlet 21 and the heater 5. It will be. When such a configuration is adopted, it is desirable to provide a filter (not shown) in front of the fine bubble pump 12 to prevent clogging of the pump 12 and the fine bubble orifice 14.

FIG. 4 mainly shows another embodiment in which the arrangement order of the device parts constituting the heating circulation circuit 3 is changed. The filtration tank 6, the circulation pump 7, the heater, the activation tank 8 and the flow rate are shown. The switching valve 9 is arranged from the hot water inlet 21 to the hot water outlet 23. Further, the flow rate switching valve 9 is electrically operated so that the branch pipe 97 is not provided. Further, in the embodiments up to FIG. 3, one mounting hole 1 is provided in the bathtub B, and the nozzle 2 provided with the hot water inlet 21, the hot water outlet 23 and the fine bubble outlet 22 is attached. However, the nozzles constituting the discharge ports 22 and 23 and the suction port 21 are separately attached to the bath B, or the hot water suction port 21 and the hot water discharge port 23 are constituted by a single nozzle, and fine bubble discharge is performed. The outlet 22 may be configured by another nozzle. However, the hot water outlet 23 and the fine bubble outlet 22
It is desirable to separate the so that the discharged hot water does not intersect. At this time, the fine bubble discharge port 22 is in the bathtub B.
It is desirable to delay the rise of fine bubbles toward the bottom as close to the bottom as possible and to quickly spread the hot water to the entire hot water in the bathtub.

FIG. 5 shows a circuit diagram of a heating circulating bath apparatus according to still another embodiment. The same parts are designated by the same reference numerals and detailed description thereof will be omitted. As apparent from the embodiments shown in FIGS. 4 and 5, in the heating circulation circuit 3,
Although the order of the filtration tank 6, the activation tank 8 and the flow rate switching valve 9 cannot be changed, the arrangements of the circulation pump 7 and the heater 5 can be changed, and the heater 5 can be changed as in the embodiment shown in FIG. It can also be configured to circulate twice.

[0020]

The present invention has the above-mentioned structure, and combines a heating circulation circuit and a fine bubble generation circuit,
Normally, the heating circulation circuit is activated and various bathing styles can be adopted such that the fine bubble generating circuit is activated at the same time according to the preference of the bather. This is because the flow rate switching valve that throttles the flow rate of the heating circulation circuit when the fine bubble generation circuit is operated is adopted, and therefore it is possible to prevent the fine bubbles from disappearing.

By providing one mounting hole in the bathtub and arranging a nozzle having a hot water discharge hole, a fine bubble discharge hole and a hot water suction port therein, a fine bubble bath with a circulating bath can be provided. Since it is sufficient to process the bathtub to the minimum necessary amount, not only is the processing time and labor consuming, but also the aesthetics of the inner wall of the bathtub is not spoiled. Further, if the fine air bubble outlet of the nozzle is provided downward and the hot water outlet is provided upward, the hot water and the fine air bubbles discharged into the hot water in the bathtub are not immediately stirred, and the fine air bubbles are directed toward the bottom of the bathtub. Since it is jetted out, all the hot and cold water in the bathtub will be stained with milky white quickly. In addition, dust and dirt that have floated up from the bather's body along with the fine bubbles toward the surface of the hot water create a ripple on the hot water surface.
Not only is it inconspicuous, but it can also be entrained in hot water and led to the filtration tank through the hot water inlet.

An electric flow rate switching valve may be provided in the heating circulation circuit so as to reduce the flow rate when the fine bubble pump is operated. However, when configured as in claim 4, the number of parts is reduced. Not only is the number reduced and the structure simplified, but it is also excellent in that the operation is reliable.
