A bubble storage means formed in the storage body and having a bubble introduction port opening in the flow path hole on the electrode body side, and water and bubbles flowing into the bubble storage space from the bubble introduction port, the electrode body and the said. between the bubble storage means, said flow path hole bore separating the inflow intervals in the circumferential form a liquid inflow path the flow path disposed Ru fluid guide body into the hole of the electrode side through the fluid guide body It has a fluid drawing hole which is formed between the fluid guide main body and the bubble storage main body and opens in a mixing space which is continuous with the liquid inflow path and the liquid outflow path. It is characterized by comprising a fluid guide means for ejecting water and bubbles from the electrode body side from the fluid throttle hole toward the inside of the bubble introduction port.

According to the first aspect of the present invention, water flows into the flow path hole from the inflow port, flows between the positive electrode and the negative electrode, flows into the fluid drawing hole, and enters the mixing space from the liquid drawing hole. It is ejected. The water that has flowed into the flow path hole from the inflow port flows through the liquid inflow path, flows into the mixing space, passes through the liquid outflow path from the mixing space, and flows out from the liquid outflow path.
When a voltage is applied between the positive electrode and the negative electrode, the electrode body electrolyzes the water flowing between the positive electrode and the negative electrode to continuously and stably generate hydrogen and oxygen bubbles. In the electrolysis of the electrode body, water, hydrogen, and oxygen bubbles including electrolyzed water flow into the liquid drawing hole and are ejected into the mixing space through the liquid drawing hole to form a turbulent flow. The liquid drawing hole allows water including electrolyzed water, hydrogen, and oxygen bubbles to flow from the flow path hole on the electrode body side, and is ejected into the mixing space toward the bubble storage space. The hydrogen and oxygen bubbles ejected into the mixing space flow into the bubble storage space from the bubble introduction port and are stored in the bubble storage space. When hydrogen and oxygen bubbles are stored in the bubble storage space, the water containing the electrolyzed water ejected from the liquid throttle hole collides with the water surface of the bubble storage space or the bubble introduction port and is repelled to the fluid guide main body side.

Due to the flow of water flowing from the liquid inflow path through the mixing space to the liquid outflow path, the bubble-mixed water is pulled (pulled) from the mixing space between the bubble storage body and the fluid guide body to the liquid outflow path. It flows through the liquid outflow channel.
As described above, in the present invention, by ejecting bubbles of water including electrolyzed water, hydrogen and oxygen into the mixing space, in addition to the turbulent flow of water, the water collides with the bubble storage space or the water surface of the bubble introduction port. By doing so, bubbles of air, hydrogen and oxygen in water can be finely crushed (sheared), and a sufficient amount (large amount) of macrobubbles and ultrafine bubbles can be mixed and dissolved in water containing electrolyzed water. Can be leaked.

In the liquid inflow path α2, the tap water W flows through each rectifying gap δ3 in the hole center line direction A of the flow path hole 7 along the rectifying front plane 61 and the rectifying back plane 62 of each rectifying plate 60.
As a result, the rectifying body 57 (each rectifying plate 60) rectifies the tap water W flowing through the liquid inflow path α2 from the electrode body 20 side (electrode flow gap δX side) and the second inflow port 9 in the hole center line direction A. Then, it flows out (spouts / jets) into the mixing space α3 toward the liquid outflow path α1.

As shown in FIG. 20, the rectified tap water W flows out (spouts / jets) into the mixing space α3 between the outer peripheral 31C of the bubble storage main body 31 and the inner peripheral 7X of the flow path hole 7, and flows into the liquid outflow path α1. Inflow.

As shown in FIG. 20, the bubble-mixed water W2 (initial / bubble-mixed water W2) is a mixing space between the bubble storage main body 31 and the fluid guide main body 55 due to the tap water W flowing from the mixing space α3 to the liquid outflow passage α1. It flows from α3 to the liquid outflow passage α1 and joins tap water W.
The tap water W flowing from the mixing space α3 to the liquid outflow path α1 draws (attracts) the bubble mixed water W2 into the liquid outflow path α1 by the flow (rectification) toward the hole center line direction A, and becomes the bubble mixed water W2. Meet.

As shown in FIG. 22, the bubble-mixed water W3 (intermediate / bubble-mixed water W3) in which the tap water W and the bubble-mixed water W2 are merged is directed toward the vortex-forming body 34 (each flow guide plate 35) of the bubble storage means 3. It flows through the liquid outflow path α1.

As shown in FIG. 23, the bubble-mixed water W3 flowing through the liquid outflow path α1 is branched (divided) at the flow diversion surface 40 of each flow guide plate 35 and flows out to the flow front plane 37 and the flow back plane 38. In the liquid inflow path α1, the bubble-mixed water W3 flows through each liquid flow gap δ1 in the hole center line direction A of the flow path hole 7 along the flow front plane 37 and the flow back plane 38 of each flow guide plate 35.
As shown in FIG. 23, the bubble-mixed water W3 flowing along the flow back plane 38 of each flow guide plate 35 flows from the flow back plane 38 along the flow slope plane 39.
Each flow guide plate 35 is changed to flow toward each vortex guide plate 36 (inner peripheral circular isolated surface 43) by the flow inclination plane 39.
As a result, the bubble-mixed water W3 flows toward the inner circumferential isolated surface 43 of each vortex guide plate 36 by the flow inclination plane 39 of each flow guide plate 35.

As shown in FIG. 24, the bubble-mixed water W3 whose flow has been changed by each flow guide plate 35 (flow gradient plane 39) flows out to the vortex space ε between each vortex guide plate 36 and the bubble storage body 31. The bubble-mixed water W3 flowing out into the vortex space ε comes into contact with the inner circular isolated surface 43 of each vortex guide plate 36 and the outer peripheral 31C of the bubble storage body 31, and the inner circular isolated surface 43 of each vortex guide plate 36. And, while being guided by the outer peripheral 31C (outer peripheral surface) of the bubble storage main body 31, it swirls and flows.
Each vortex guide plate 36 swirls and flows the bubble-mixed water W3 while guiding it on the inner peripheral circular isolated surface 43.
From this, the vortex forming body 34 is formed around the outer circumference of the bubble storage main body 31 in the bubble mixed water W3 flowing through the liquid outflow path α1, and the inner peripheral circular isolated surface 43 of each vortex guide plate 36 and the bubble storage main body 31. A vortex flow σ along the outer circumference 31C is formed (generated).
The vortex flow σ is a vortex flow centered on the hole center line a (cylinder center line b of the bubble storage main body 31) of the flow path hole 7, and is, for example, rotated (swiveled) in the clockwise direction.
As shown in FIGS. 23 and 24, the vortex flow σ is formed from each vortex flow guide plate 36 (each flow guide plate 35) over the liquid outflow path α1 on the fluid guide main body 55 side (electrode body 20 side), and each vortex flow. From the guide plate 36 (vortex flow forming body 34), the flow path hole 7 is passed to the outlet 10.
Since the bubble storage main body 31 guides (guides) the vortex flow σ at the outer circumference 31C, it constitutes the vortex flow forming body 34.

The bubble-mixed water W3 becomes a turbulent flow due to the vortex flow σ, and flows through the liquid outflow path α1 and the flow path hole 7. Cavitation (cave phenomenon) occurs in the bubble-mixed water W3 due to the pressure difference of the eddy current σ.
As a result, the air (bubble BU) in the bubble-mixed water W1 is further increased by a sufficient amount (major amount) of micro-unit bubble BU (microbubbles) and a sufficient amount (major amount) due to turbulence and cavitation. It is crushed (sheared) into nano-sized bubbles BU (ultra fine bubbles).
The micro-unit bubble BU and the nano-unit bubble BU that have been finely crushed (sheared) again by the vortex flow σ are mixed and dissolved in the bubble-mixed water W3, and become the bubble-mixed water W4 (final / bubble-mixed water W4). Become. As shown in FIG. 22, the bubble-mixed water W4 flows out from the outlet 10 through the flow path hole 7.

In this way, the bubble generator X ejects (injects) the tap water W1 and the bubble BU from the fluid throttle hole 56 into the mixing space α3, so that the air and the bubble BU of the tap water W1 are temporarily and finely crushed (injection). By further forming a vortex flow σ by shearing), air, hydrogen and oxygen in the bubble-mixed water W can be finely crushed (sheared), and a sufficient amount (large amount) of micro-unit bubble BU (microbubbles) can be obtained. ), And a sufficient amount (many amount) of nano-sized bubble BU (ultrafine bubble) can be mixed and dissolved in tap water W (water W).
In the bubble generator X, the first inflow port 8 is not limited to the configuration formed by opening in the hole inner circumference 7X of the flow path hole 7, and is opposed (opposed) to the positive electrode 23 and the negative electrode 24, that is, the positive electrode 23. And the negative electrode 24 may be opposed to each other. For example, a configuration may be adopted in which the tube body 5 is formed by opening at the other tubular end 5B and faces the positive electrode 23 and the negative electrode 24.

As shown in FIG. 25, the bubble generator X is installed (arranged) in, for example, the wash unit Z. The wash basin Z includes a wash basin 101, a wash basin 102 (wash basin), a faucet 103 (faucet), and the like. The wash basin 102 is installed on the wash basin 101. The wash bowl 102 has a drain port 104 connected to a drain pipe (not shown).
The faucet 103 is arranged on the wash basin 102 and attached to the wash basin 101 or the wash basin 102. The faucet 103 is connected to the water supply pipe 105, and the water supply pipe 105 is connected to a water supply source (not shown).
As shown in FIG. 25, the bubble generator X is arranged on the faucet 103 side (near the faucet 103) in the water supply pipe 105. The bubble generator X is housed and arranged in the wash basin 101.

In FIG. 25, tap water from a water supply source (not shown) flows from the water supply pipe 105 to the main introduction cylindrical pipe 13 (introduction pipe body 6) of the bubble generator X, and the main introduction cylindrical pipe 13 and the branch introduction cylindrical pipe. It flows into the flow path hole 7 of the liquid flow path body 1 from the first and second inflow ports 8 and 9 through 14 (see FIGS. 4 and 7).

In FIG. 25, the bubble generator X causes the bubble-mixed water W4 to flow out to the water supply pipe 105 on the faucet 103 (faucet) side in the same manner as described with reference to FIGS. 19 to 24. The bubble-mixed water W4 flows from the faucet 103 into the wash bowl 102 through the water supply pipe 105.
The bubble-mixed water W4 flowing out to the wash bowl 102 exhibits excellent cleaning and sterilizing effects by microbubbles and ultrafine bubbles.

The bubble generator X is not particularly limited to being installed in the washbasin unit Z. For example, the bubble generator X may be installed in a bathtub to eject (inflow) water containing bubbles W4 into the bathtub. Water mixed with air bubbles W4 may be ejected (injected) from the injection hole of the shower head.

The present invention is most suitable for mixing and dissolving macro-unit bubbles (microbubbles) and nano-unit bubbles (ultrafine bubbles) in tap water (water).
