場合がある。However, in the above configuration, the pump 1 is usually used when the fine bubble water flow operation is used.
When the valve 03 operates, the hot water 102 is sucked into the pump 103 from the inhaler 106 via the suction side pipeline 105. Hot water 10
When 2 is inhaled, the relief valve 126 becomes a discharge resistance, and the pump 103, the discharge side pipeline 107, and the shuttle valve 113 are brought into a high pressure state almost instantaneously.
However, when air is generated by the pump 103, the air is repeatedly compressed and depressurized, so that it is difficult to attain a high pressure state. This is because when the operation of generating the microbubble water flow is completed, the pressure inside the pump 103 is reduced from the high pressure state to return to the atmospheric pressure. This is because the air stays in the inner space 103 and the air becomes stagnation when restarting. Also, the discharge side pipeline 10
7. The air is re-gasified by the relief valve 126 in the same manner as described above, and the air from the pump 103 is observed. Further, when the hot water 102 in the bathtub 101 is drained, the hot water 102 in the suction-side conduit 105 is also entirely drained or partially drained in the same manner.
When the pump 103 is operated, a large amount of the air may be sucked into the pump 103 in some cases.

ができる。According to the above means, in the bubble water flow generating device of the present invention, the air pressurized and dissolved in water is re-gasified by stopping the operation of the pump. The re-gasified air and undissolved air staying in the feed line including the pump, the circulation circuit and the fine bubble discharge portion, and the air in the return line, which is trapped in the re-watering operation after draining the water tank, are reduced. Let it drain on time. That is, when the control means detects the presence of drainage in the drainage detection unit, the control unit sets the throttle area of the variable throttle unit for pressurization to a large value, and after operating the pump for a certain period of time, sets the throttle area to a small value. To open the air inlet. Therefore, in the variable pressurizing section with a low discharge resistance,
In addition, when a certain period of time has elapsed after the operation of the pump, water immediately flows into the pump from the return line. At this time, the air staying in the return line also flows into the pump at the same time, and the air is immediately discharged from the pump although the air is removed. The discharged air-mixed water almost flows to the feed pipe side having a low resistance, and the air-mixed water is discharged from the fine bubble discharge section to the variable resistance pressurizing section having a low resistance. As a result, the pump can be brought into a normal operation state reliably and stably.

することができる。On the other hand, when the drainage detecting section detects no drainage, the control means sets the throttle area of the variable throttle section for pressurization to a small value to operate the pump, and after a predetermined time has elapsed, opens the air inflow device. Allow air to flow in. Therefore, since drainage of the water tank is not performed, there is no inflow of air into the return pipe, and when a certain time elapses after the pump is operated in the variable pressure restrictor for pressurization where the normal discharge resistance remains large, Since it is only necessary to discharge only the regasified air and undissolved air in the pump, circulation circuit, and feed pipe, reduce the throttle area of the variable throttle for pressurization from large to small as when draining is performed. In addition, the pump can be stably brought into a normal operation state in a short time.

解し、微細気泡の初期発生時間の高速化が可能となる。After the control means sets the throttle area of the variable pressurizing throttle section to a small value, the control means opens the air inflow device to flow air. In this way, the air inflow device must be opened only after the throttle area of the variable throttle for pressurization is set to be small. The reason is that when the pump is operating, the ejector section is in a high negative pressure state, and if the air inflow device is open, a large amount of air flows in due to the high negative pressure, and The pump is in a stagnation state and the pump cannot operate normally. This is because the feed pipe and the circulation circuit do not have a high pressure, so that the air does not dissolve and fine bubbles cannot be generated even after a long time. On the other hand, normal operation of the pump in a short time means not only the durability of the pump, but also the high pressure in a short time, and the inflowing air is almost instantaneously pressurized and dissolved, and the initial generation time of fine bubbles Can be speeded up.

る。According to the second technical means of the present invention, the control means operates the operation switch [OFF] to close the air inflow device and then reduce the bubble water flow generating condition by reducing the throttle area of the variable throttle for pressurization. After a certain period of time has elapsed, the operation of the pump is stopped. Therefore, the air to be regasified and the undissolved air in the pump, the circulation circuit and the feed line can be discharged at the end of the operation without air from the outside and can be discharged at a high pressure in a short time during the operation. Is possible.

After that, the operation of the pump is stopped. Therefore, air can be discharged more quickly at the end of operation, and the pressure can be increased in a short time at the time of restart.

In addition, the correspondence according to the purpose of use can be widely utilized.

Then, the pump 5 in a state filled with water rotates, and a part of the discharged circulating water is supplied from the discharge part 12 to the feed line 3,
The fine circulating water is discharged from the water discharge section 2 to the water tank 1 through the variable throttle section 13 for pressurization, and the circulating water remains in the circulation circuit section A.
Circulate. When this circulation is performed, the ejector section 8 functions, and the water 4 in the water tank 1 is sucked into the negative pressure section 8a of the ejector section 8 via the return line 17. When the water 4 is sucked into the return portion 7 of the pump 5 via the ejector portion 8,
The pressure on the suction side of the pump 5 increases. If the pump 5 continues to operate in this state, the pressure on the discharge section 6 side is also increased. That is, since the pressure variable throttle portion 13 of the feed pipe line 3 is slightly contracted, the pump 5 is operating in a substantially shutoff operation state. Therefore, the pressure on the return portion 7 side is increased, and the cutoff pressure of the pump 5 is applied, so that the pressure is increased. In such an operating state, the air inflow unit 15 is also operated by the control means 20, so that air flows in and the air inflow unit 1
From 0, it is sucked into the negative pressure section 8a of the ejector section 8. This air enters the pump 5 from the return section 7 and is sent from the discharge section 6 to the circulation circuit section A and the feed line 3. At this time, since the inside of the circulation circuit portion A and the feed pipe line 3 has a high pressure, the air previously sucked is in a state of being dissolved in the water 4. Then, when the water in which the air is dissolved passes through the pressurizing variable throttle unit 13, the pressure is rapidly reduced, and the dissolved air becomes fine bubbles and spreads to the water tank 1 from the fine bubble water flow discharge unit 2. Also,
When such an operation is stopped, the air dissolved in the water in the bubble water flow generating means is no longer pressurized in the means, and is again gasified and stays as air.

The point of the above is that the circulating water 11 discharged from the discharge part 6 of the pump 5 is branched from the bypass water discharge part 12 to the feed pipe 3 side and the ejector part 8 side and flows. The pressure is increased by the three elements, ie, the variable pressurizing throttle unit 13 and the ejector unit. In the conventional example, the means for dissolving the air under pressure under high pressure is a relief valve 126.
The gas-liquid mixer 122 provided with the spiral passages 120 and 121 alternately provided for the main pressurized dissolution of air, but in the present invention, the circulation circuit section A including the pump 5 is used for the main pressurized dissolution of air. . That is, the feed line 3 side flow rate Q1 and the ejector section 8
In the side flow rate Q2, by setting Q2> Q1, Q
Assuming that the 2 / Q1 ratio is the number of circulations, air can be sufficiently pressurized and dissolved by increasing the number of circulations. Further, the circulation circuit portion A also has a buffer effect to reduce air stagnation of the pump 3 in particular. That is, even if the air dissolved under pressure is re-gasified, the air easily stays in the circulation circuit portion A. Next, the second point is the water 4
A drainage detecting section 19 for detecting whether or not the water is drained from the drainage port 18 is disposed in a part of the return pipe 17. That is, the air staying in the return pipe line 17 generated by the general usage is generated by draining the water 4 from the water tank 1 and re-injecting the water. However, the air hardly stays in the return line 17 when the water is not drained. The initial control is varied depending on the presence or absence of the drainage. Next, the third point is that the throttle area S1 of the variable pressurizing portion 13 provided in a part of the feed pipe 3 (during the operation of generating the bubble water flow).
This is a point that the throttle area S2 can be made larger than that (at the time of discharging the re-gasified air-mixed water). Then, the presence or absence of the above-described drainage is detected by the drainage detection unit 19, and the throttle area of the variable pressure throttle unit 13 is changed from S1 or S2 to S1.

気泡の初期発生時間が、より安定高速化できる。Also, the configuration in which the variable pressure diaphragm 13 for pressure of the present invention is provided and the diaphragm areas S1 and S2 of the variable pressure diaphragm 13 for pressure are set to S2> S1, preferably S2 >> S1 to reduce the resistance. By setting S2, when the presence of drainage is detected, even if the air staying in the return line 17 flows into the pump 5, the air is immediately discharged at a large flow rate. Although a part of the discharged air mixed water is recirculated in the circulation circuit part A, most of the discharged air mixed water flows toward the pressurizing variable throttle part 13 of the feed pipe 3 having low resistance, and is easily discharged from the fine bubble discharge part 2. You. Therefore, the pump 5 is brought into the normal operation state in a short time, and the pressure can be increased as soon as the throttle area of the variable throttle for pressurization is set to S1, and the opened air inflow device 15 is opened.
The air that has flowed in from the air is almost instantaneously pressurized and dissolved, and the initial generation time of the fine bubbles can be stabilized and speeded up.

When the operation is started by turning on the operation switch in S-1, first, in S-2, the drainage detector 19 detects the presence or absence of drainage. That is, when there is no drainage, the throttle area S1 of the variable throttle unit 13 for pressurization is set in S-3, the air inflow unit 15 is opened in S-6 after the operation of the pump 5 is started, and the operation for generating the bubble water flow is started.

When the pump 5 is turned on, the process proceeds to S-5, and the timer of the control means 20 is operated to check whether the pump 5 has been turned on for a predetermined ON time ΔtON. When the time ΔtON has elapsed, the flow shifts to S-6, where the air inflow device 15 is turned on (opened). As a result, the air that has flowed into the circulating water circuit portion A becomes pressurized dissolved air in the water, and is instantaneously depressurized by flowing through the feed pipe 3 and discharged from the variable pressurizing portion 13 for pressurization. 2 is discharged.

Upon completion of the resetting, the flow shifts to S-11, where the air inflow device 15 is opened. As a result, the air for regasification in the water in the feed line 3, the pump 5, etc. has already been exhausted, and the air flowing into the circulating water circuit section A is dissolved under pressure in the water, and the bubble water flow as described above.
