- the tank 131 is connected to a water supply line (not shown) and accumulates a predetermined amount of water (tap water) from the line by a float valve or the like.
- the flow path 132 is attached to the bowl 10 with its upstream end inlet located at the bottom of the tank 131, and the downstream end outlet of the flow path 132 is directed toward the rim 100 c in the container 100. Accordingly, the water in the tank 131 is discharged from the outlet of the flow path 132 into the container 100 directly or through the rim portion of the container 100 as flush water.
- the fine bubble generator 14 includes a circulation unit 140, which includes a circulation channel 141 having both ends connected to a tank 131, and a pump 142 placed between both ends of the channel 141.
- the pump 142 is a driving source for the entire microbubble generator 14 and is operated by, for example, a human sensor switch or a manual switch, and sucks water from the inlet 141a at one end of the channel 141. Then, the water is pushed out from the outlet 141b at the other end of the channel 141, whereby the water in the tank 131 is circulated through the channel 141.
- the generator 14 includes a gas mixing part 143, a dissolving part 144, and a rapid pressure changing part 145 as a precipitation part arranged in this order from the inlet 141a to the outlet 141b.
- the gas mixing unit 143 includes a valve 143a connected to a gas supply source (for example, ambient air such as air in a toilet room) via another line, and an ejector mechanism (not shown). Water from the supply line is mixed with gas (for example, air) from the other line, and the gas mixture water is supplied to the dissolving unit 144.
- the valve 143a is a check valve, and allows gas to pass from another line into the flow path 141, while preventing water from flowing back from the flow path 141 to the other line.
- the ejector mechanism is a negative pressure generator such as a throttle formed in the flow path 141, and this generator is connected to the output of the valve 143a.
- the gas is naturally drawn into the channel 141 by the ejector effect obtained from the flow of water in the channel 141.
- the gas from the gas supply source may be forced into the flow path 141 by an air pump or the like.
- the dissolution unit 144 includes the pump 142 as a constituent element, and dissolves part or all of the gas in the gas mixture water in the water under a high-pressure environment by the pump 142 to rapidly pressurize the gas dissolved water.
- Supply to Transformer 145 the melting section 144 is a melting tank, and is divided into a primary tank (a bubbling tank) 144b and a secondary tank (a water level detection tank) 144c that are separated by a partition 144a, and a primary tank. It has an inlet 144d formed at the upper part of the tank 144b, and an exhaust outlet 144e and an outlet 144f formed at the upper side and the lower part of the secondary tank 144c, respectively.
- the tanks 144b and 144c are communicated with each other via an upper gas reflux hole and a lower water passage hole.
- the inlet 144d includes a spray nozzle 144g, and creates a publishing state by spraying the gas mixture water injected from the pump 142 toward the primary tank 144b at a high speed.
- part of the gas in the gas mixture water is dissolved in the water in the dissolution tank before reaching the outlet 144f via the water passage hole.
- Supplied to the pressure changing unit 145 Supplied to the pressure changing unit 145.
- the remaining portion of the gas ascends in the secondary tank 144c, and then returns to the primary tank 144b through the gas reflux hole or is exhausted to the outside through the exhaust port 144e. In this case, the excess gas is exhausted to the outside through the exhaust port 144e, so that the water level in the dissolution tank is kept constant.
- the sudden pressure changing section 143 is disposed at the outlet 141b of the circulation flow path 141, and suddenly changes the pressure of the gas-dissolved water so that the bubble diameter from the gas-dissolved water is 0.1 to: lOOO xm Then, fine bubbles mixed with the washing water are precipitated and generated.
- the sudden pressure changing portion 143 is a nozzle having a special shape, and is assembled by turning the screw convex portion 1431a on the outlet side of the upstream member 1431 into the screw hole 1432a on the inlet side of the downstream member 1432.
- the upstream member 1431 has a truncated cone-shaped hole 1431b whose bottom is disposed at the inlet, and a groove 1431c having a semicircular cross section and formed on the end surface on the outlet side.
- the downstream member 1432 is formed in a revolver (handgun) magazine shape having a plurality of holes 1432b (for example, six holes), and each hole 1432b is opposed to the groove 1431c.
- a minute gap (microchannel) 1430 force is formed between the end face on the outlet side of the upstream member 1 431 and the end face of the central part of the downstream member 1432, and the groove on the outlet side of the gap 1 430 1431c
- the area on the side is the area where whispering occurs.
- Bubbles with a bubble diameter gather at the outer periphery, while bubbles with a larger bubble diameter gather at the center, and bubbles below the specified diameter at the outer periphery are continuously in the tank 131 from the outer periphery of the vortex with the washing water.
- the force that the bubbles with a large bubble diameter accumulate in the center has a shearing force due to its radial velocity gradient, so the bubble has a large bubble diameter. Air bubbles are reduced by the shearing force when moving to the outer periphery by centrifugal force.
- the bubble diameter of the fine bubbles is determined by the angular velocity of the vortex in the region where vortexing occurs, and the smaller the smaller the angular velocity, the smaller the bubble size of the fine bubbles by adjusting the flow rate from the gap 1430 to the region. Can be set to a desired diameter.
- the fine bubbles are adsorbed to the suspended matter and floated and separated, and the surface is negatively charged, and electrostatically adsorbed to the suspended matter to enclose the suspended matter.
