First, when the operation switch 9 is operated to start the operation and the operation switch 9 is turned on, an operation start signal from the operation switch 9 is sent to the control unit 11, and by the control signal from the control unit 11,
At the same time when the solenoid valve 5 is opened, the motor 16 is turned on and the pump 7 is operated. Therefore, the bath water in the bathtub 1 is sucked from the hot water inlet 2, and the air in the atmosphere is sucked from the air supply unit 6 and sucked into the pump 7. Bath water and air drawn into the pump 7 is about 6 kg inside the pump 7.

る。The fine bubbles are generated in the bathtub 1 in this way. When it is desired to stop the generation of the fine bubbles, the operation switch 9 is turned on again by operating the operation switch 9, and the operation stop signal is sent to the control unit 11. To the solenoid valve 5 at the same time when the operation of the operation switch 9 is stopped by the signal from the control unit 11.
Is closed and the air supply is stopped, but the control means 11
The delaying means 10 provided in the above makes it possible to stop the operation of the pump 9 by turning off the motor 16 after a fixed time elapses from the closing of the solenoid valve 5. Therefore, the operation switch 9 is operated to stop and the air supply is stopped at the same time as the operation stop signal is sent. However, the operation of the pump 7 is continued for a certain period of time after the air supply is stopped, and the air in the water channel 4 is added. The pressure-dissolved water is discharged into the bath 1. Then, the pressurized dissolved water of the air in the water channel 4 is discharged into the bath 1 and then the pump 7 is stopped. For this reason, the delay time until the operation of the pump 7 is stopped is determined in advance at the time when the pressurized dissolved water of the air in the water channel 4 is completely discharged into the bathtub 1, and at the same time or a little less than this. The operation of the pump 7 is stopped after a delay. As the delay means 10, for example, a timer or a microcomputer can be used. By providing the delay unit 10 as described above and stopping the operation of the pump 7 after continuing the operation of the pump 7 for a certain period of time after stopping the supply of air, no pressurized dissolved water of air remains in the water channel 4. When the pressure-dissolved water remains in the water channel 4 while the operation is stopped, the pressure-dissolved water is decompressed and the dissolved air is deposited, so that the water and the air are separated and remain in the water channel 4. As a result, when the operation switch 9 is re-operated and the pump unit A is restarted, the air deposited in the water channel 4 in the initial stage of the restart becomes a large bubble from the injection port 3. Therefore, it is possible to eliminate the problem that the liquid is discharged into the bathtub 1 as a result.

れることになる。FIG. 6 is a time chart showing the operation of this embodiment. The operation of this embodiment will be described below based on this time chart. First, when the operation switch 9 is operated to start the operation and the operation switch 9 is turned on, an operation start signal from the operation switch 9 is sent to the control unit 11, and the solenoid valve 5 is operated by the control signal from the control unit 11. At the same time, the motor 16 is turned on and the pump 7 is operated. Therefore, the bath water in the bathtub 1 is sucked from the hot water inlet 2, and the air in the atmosphere is sucked from the air supply unit 6 and sucked into the pump 7. The bath water and air sucked into the pump 7 are pressurized to about 6 kg / cm 2 inside the pump 7, and the air is pressurized and dissolved in the bath water and sent to the injection port 3 side. On the way, rectification is performed by the accumulator 8 to separate pressurized dissolved water of air and surplus air, the surplus air is exhausted to the atmosphere from the exhaust unit 14, and only the pressurized dissolved water is conveyed to the injection port 3. To be done. Here, there is a case where the exhaust unit 14 partially discharges the water together with the exhaust. The pressurized dissolved water sent to the injection port 3 through the accumulator 8 is depressurized by the pressurized dissolved water of air at the injection port 3, and about 10 wire meshes of about 100 mesh built in the injection port 3 are bundled. By passing through a net cartridge (not shown), fine bubbles having a diameter of about 10 μ are generated and are discharged into the bath 1.

うなことがない。The fine air bubbles are generated in the bathtub 1 in this way. When it is desired to stop the generation of the fine air bubbles, the operation switch 9 is turned on again by operating the operation switch 9. To the solenoid valve 5 at the same time when the operation of the operation switch 9 is stopped by the signal from the control unit 11.
Is closed and the supply of air is stopped, and at the same time, the switching valve control means 13 switches the switching valve 12 so that the drain portion 15 side is open and the injection port 3 side is closed.
The delaying means 10 provided in the above makes it possible to stop the operation of the pump 7 by turning off the motor 16 after a certain time delay from the closing of the solenoid valve 5. Therefore, the operation switch 9 is operated to stop and the air supply is stopped at the same time as the operation stop signal is sent. However, the operation of the pump 7 is continued for a certain period of time after the air supply is stopped, and the air in the water channel 4 is added. The pressure-dissolved water is drained from the drainage unit 15 to the outside of the system. And waterway 4
The pump 7 stops its operation after the pressurized dissolved water of the inside air is drained from the drainage section 15. When the operation of the pump 7 is stopped, the switching valve control means 13 switches the switching valve 12 so that the drain portion 15 side is closed and the injection port 3 side is opened. Therefore, the delay time until the operation of the pump 7 is stopped is determined in advance at the time when the pressurized dissolved water of the air in the water channel 4 is completely discharged from the drainage unit 15, and at the same time or a little less than this. The operation of the pump 7 is stopped after a delay. As the delay means 10, for example, a timer or a microcomputer can be used. By providing the delay means 10 as described above, the pump 7 can be operated for a certain period of time after the air supply is stopped.
The operation of the pump 7 is stopped after the operation of No. 1 is continued, and the switching valve control means 13 causes the switching valve 12 to be closed at the same time as the electromagnetic valve 5 is closed on the drain side and the injection port 3 side. By switching and switching the operation of the pump 7 so that the drain valve side is closed and the injection port 3 side is opened when the operation of the pump 7 is stopped, no pressurized dissolved water of air remains in the water channel 4, and when the operation is stopped. When the pressure-dissolved water remains in the water channel 4, the pressure-dissolved water is decompressed and the dissolved air is deposited, so that the water channel 4
As a result, the situation where water and air are separated and left inside is not caused, and as a result, when the operation switch 9 is re-operated to restart the pump unit A, the water channel 4 is restarted at the initial stage of restarting. This prevents the air that has been deposited inside from becoming a large bubble from the injection port 3 and being discharged into the bathtub 1. Moreover, since the switching valve 12 is switched so that the drain portion 15 side is open and the injection port 3 side is closed at the same time as the operation of the operation switch 9 is stopped, the injection from the injection port 3 into the bathtub 1 is stopped. At the same time when the operation of the operation switch 9 is stopped, the injection from the injection port 3 is stopped, and even though the operation is stopped, the injection is performed from the injection port 3 for a certain period of time, which makes the user feel uncomfortable. There is no such thing.
