Abstract

PROBLEM TO BE SOLVED: To provide an ozone water production apparatus capable of completely separating undissolved ozone. SOLUTION: Ozone water introduced through a water-feeding port 3 into an ozone water tank 5 is divided into right and left streams by a guiding wall 9 and passed through respective flow channels 10a, 10b to the back of the guiding wall 9. The ozone mixed in the form of bubbles is concentrated to the back of the guiding wall 9 without being pulled into a lower outlet port. The ozone bubbles concentrated at the back of the guiding wall 9 are transferred through an outlet port 8 opened on a ceiling holding the guiding wall in suspended state and are introduced into a float chamber. Accordingly, there is no trouble of the pulling of ozone bubbles into the flow directing toward the lower outlet port to cause the ejection of the ozone through the ejection nozzle.

Detailed Description of the Invention

[0001]

[0001] The present invention relates to an ozone water producing apparatus.

[0002]

2. Description of the Related Art In a conventional ozone water producing apparatus, as shown in FIG. 4, ozone from an ozone generator a is dissolved and mixed in tap water by an ozone dissolving device (ejector) b. The ozone water in which the ozone is dissolved enters the excess ozone separation device c, and the ozone that is not completely dissolved in the water and is mixed in the form of bubbles is separated as excess ozone. Excess ozone flows out to the ozone decomposing device d, is reduced to oxygen and is released into the atmosphere.

[0003]

However, since the ozone water vigorously flows in from the water supply port f of the ozone water tank e of the surplus ozone separation device c, the ozone that hits the inner wall of the ozone water tank e facing the water supply port f. The water stream is vertically and horizontally divided and swirled. A part of the flow split down,
The ozone water is drawn into the flow toward the discharge port g provided below the tank e and flows out from the discharge port g. Since ozone is mixed as bubbles in the ozone water flowing into the ozone water tank e, there is a problem that ozone flows out from the discharge port g as it is. The present invention has been made to solve the above problems, and an object of the present invention is to provide an ozone water producing apparatus that completely separates undissolved ozone and does not flow out from a discharge port. .

[0004]

The ozone water producing apparatus of the present invention for achieving the above object comprises an ozone generating means and an ozone dissolving means for dissolving ozone generated by the ozone generating means in water supplied under pressure. In the ozone water producing apparatus including means and surplus ozone separating means for separating surplus ozone, from the ceiling wall of the ozone water tank of the surplus ozone separating means, along with the inner circumference of the ozone water tank, A guide wall facing the water inlet to be introduced is formed, and an ozone water flow hitting the guide wall is spilled around the back side of the guide wall, and excess ozone is discharged from an outflow hole provided in the ceiling wall. Characterize

[0005]

According to the ozone water producing apparatus having the above-mentioned structure, the ozone water flowing into the ozone water tank from the water supply port hits the guide wall, is diverted, and flows along the inner circumference of the ozone water tank. Go around the back of the guide wall. As a result, ozone mixed in a bubble state is concentrated on the back side of the guide wall without being drawn into the lower discharge port. Then, ozone in the form of bubbles can be made to flow out from the outflow hole provided in the ceiling wall of the ozone water tank and completely separated. Therefore,
Air containing ozone does not flow out of the discharge port as it is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to the accompanying drawings. 1 is a schematic configuration diagram of an ozone water producing apparatus 1 according to the present invention, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a sectional view taken along line BB in FIG. The surplus ozone separation device 2 of the ozone water production device 1 includes an ozone water tank 5 having a water supply port 3 on the upper side and a discharge port 4 on the lower side, and a float chamber 6 disposed on the upper surface thereof. You.

An outlet hole 8 is formed in the ceiling wall 7 of the ozone water tank 5 having a circular cross section and communicates with the float chamber 6. A lower end of the ceiling wall 7 is lowered to the position of the water supply port 3 so as to face the water supply port 3 and a semi-circular guide wall 9 is formed along the inner circumference of the ozone water tank 5. . The guide wall 9 is formed so as to surround a substantially half circumference of the outflow hole 8 on the water supply port 3 side. As a result, the water supply port 3 is provided between the guide wall 9 and the inner circumference of the ozone water tank 5.
Flowing water channels 10a, 1a that divide the ozone water that flows in from the guide wall 9 and strikes the guide wall 9 to the left and right, and circulates it around the back side of the guide wall 9.
0b is formed.

On the upper surface of the float chamber 6, the float chamber 6
An on-off valve 12 is provided which closes when the float 11 that follows the water level is closed and opens when it descends. The on-off valve 12
The float chamber 6 and the ozone decomposing device 13 are communicated with each other via. The ozone decomposing device 13 is a surplus ozone separating device 2
The excess ozone separated by is reduced to oxygen and released into the atmosphere. An ozone dissolving device (ejector) 15 is connected to the water supply port 3 of the ozone water tank 5 via a connecting hose 14.

The ozone dissolving device 15 comprises a pipe joint 16 branched into a T-shape, and an ozone supply pipe 17 connects an ozone generator 18 and a connecting hose 19 to a water faucet (not shown). Then, ozone supplied from the ozone generator 18 is dissolved in tap water to produce ozone water. A spout nozzle 21 is connected to the discharge port 4 by a connecting hose 20.

The ozone water producing apparatus 1 having the above-described structure dissolves and mixes the ozone from the ozone generator 18 with the tap water supplied to the ozone dissolving apparatus 15 to produce ozone water and eject it from the ejection nozzle 21. However, the ozone water that has passed through the ozone dissolving device 15 contains ozone that is not completely dissolved in the form of bubbles. When this ozone water flows into the ozone water tank 5 from the water supply port 3, the ozone water hits the guide wall 9 and splits into left and right, flows in the flowing water channels 10a and 10b, and wraps around the back side of the guide wall 9. As a result, the ozone mixed in the bubble state is concentrated on the back side of the guide wall 9 without being drawn into the discharge port 4 below.

Ozone in the form of bubbles concentrated on the back side of the guide wall 9 flows into the float chamber 6 through an outflow hole 8 formed in the ceiling wall 7 from which the guide wall 9 hangs. Ozone is float chamber 6
The buoyancy of the float 11 decreases as it flows into and accumulates.
Therefore, the float 11 descends and the on-off valve 12 is opened, and excess ozone flows out to the ozone decomposing device 13, is reduced to oxygen and is released into the atmosphere.

As mentioned above, the ozone contained in the ozone water flowing into the ozone water tank 5 in the form of bubbles is guided by the guide wall 9
At this time, the ozone flows in the flowing water channels 10a and 10b, goes around to the back side of the guide wall 9, and immediately flows into the float chamber 6 from the outflow hole 8.
It will not be drawn into the flow toward and jetted from the jet nozzle 21. Therefore, the ozone water tank 5 of the surplus ozone separator 2 is irrespective of the fluctuation of tap water pressure.
In it, the surplus ozone can be completely separated.
