Abstract

PROBLEM TO BE SOLVED: To stabilize a produced pH value by a control method in which the flow rate range of a flow rate section in the control of voltage applied to an electrolytic cell is widened from a low flow rate area toward a high flow rate area even when a flow rate is varied. SOLUTION: In a water conditioner, when water is passed through an alkali ion water conditioner 3, the flow rate section of the flow rate of water being passed through the conditioner 3 is judged by a flow rate section determination means 22, and voltage to be applied is corrected corresponding to the judgement. When the flow rate is varied, the produced pH value of produced alkali ion water or acidic ions is varied largely; however, control is made by a control method in which the flow rate range of a flow rate section is widened from a low flow rate area toward a high flow rate area to stabilize a produced pH value.

It is a control method that becomes a numerical sequence value,
Similarly, it has the effect of stabilizing the generated pH value.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1) FIG. 1 is a schematic configuration diagram of an alkali ion water conditioner according to Embodiment 1 of the present invention. The same components as those in the conventional technique are denoted by the same reference numerals.

In FIG. 1, 1 is a raw water pipe for tap water or the like, 2 is a faucet, 3 is an alkali ion water conditioner, 4 is a water purification section, 5 is a flow rate sensor, 6 is a calcium supply section, 7 is an electrolytic tank, 8 Is a diaphragm, 9 and 10 are electrode plates, 11 is a drain pipe, 12 is a flow control unit, 13 is a discharge pipe, 14 is a solenoid valve, 15 is a discharge pipe,
16 is a water purification section detection sensor, 17 is a plug for turning on the power, 1
8 is a power supply unit, 19 is a control unit, 20 is an operation display unit, 21
Are solenoid valves, which have basically the same configuration as that of the above-mentioned conventional technology, and thus the description thereof is omitted.

In the alkali ion water purifier of the first embodiment, as one of the components of the control means 19, the magnitude of the flow rate is determined based on the signal from the flow rate sensor 5, and to which flow rate section it belongs. It is characterized in that a flow rate classifying means 22 for determining whether or not is provided.

The operation of the alkali ion water conditioner 3 of the first embodiment configured as described above when generating the alkali ion water will be described below.

The user presses a mode selection button on the operation display section 20 to select and set an alkaline ionized water generation mode, an acidic ionized water generation mode or a purified water mode. Selects a desired pH intensity with the pH intensity setting button of the operation display section 20. Next, the faucet 2 is opened, and the raw water passed through the faucet 2 is subjected to removal of impurities such as residual chlorine, trihalomethane, mold odor, and general bacteria in the raw water in the water purification section 4 and supply of calcium through the flow rate sensor 5. After calcium glycerophosphate and calcium lactate are dissolved in the part 6 and treated with water that can be easily electrolyzed, the electrolytic cell 7
Is passed through.

On the other hand, AC1
00V is supplied, and a DC voltage and current necessary for electrolysis are generated by a transformer and a control DC power supply in a power supply unit 18, and the electrode plates 9 and 10 of the electrolytic cell 7 are controlled via a control unit 19.
Is supplied with power required for electrolysis. At this time, if the electrode plate for applying a relatively positive voltage is an anode and the electrode plate for applying a negative voltage is a cathode, an anode chamber and a cathode chamber separated by a diaphragm 8 are formed in the electrolytic cell 7. In the alkaline ionized water generation mode, the electrode plate 10 functions as an anode, and the electrode plate 9 functions as a cathode. In the acidic ion water generation mode, the electrode plate 9 becomes an anode, and the electrode plate 10
Becomes the cathode.

After the water flow, the control means 19 reads the signal of the flow rate sensor 5, and when the flow rate level exceeds a certain amount, judges that the state is water flow, applies a predetermined voltage to the electrolytic cell 7, and sets a predetermined voltage. The alkaline ionized water or the acidic ionized water is generated according to the ion water generation mode being used.
Thereafter, when the flow rate level falls below a certain amount, this state is determined to be water stoppage, and the voltage application to the electrolytic cell 7 is terminated. When it is determined that the water is passed, the flow rate classifying means 22 determines which flow rate the flowed water belongs to, and corrects the applied voltage accordingly. At this time, if the flow rate fluctuates, the generated pH value of the generated alkaline ionized water or acidic ion greatly changes. In the first embodiment, however, the flow rate range of the flow rate section changes from a low flow rate range to a high flow rate range. Accordingly, since the control system is provided with a control system which is broadened according to the above, the fluctuation of the generated pH value can be suppressed in any flow rate range.

FIG. 5 is a graph showing the variation in the pH value of a conventional alkaline ionizer. From this graph, it can be seen that the fluctuation of the generated pH value within the same flow rate section in the low flow rate range is large.

FIG. 2 shows Embodiment 1 of the present invention.
5 is a graph showing a variation in the pH value of the generated alkaline ionizer. From this graph, it can be seen that the variation in the generated pH value within the same flow rate section is small in any flow rate range.

As described above, according to the alkali ion water conditioner of the first embodiment, even when the flow rate fluctuates, the flow rate range of the flow rate section in the voltage control applied to the electrolytic cell is changed from a low flow rate range to a high flow rate range. As it becomes, the generated pH value can be stabilized by a control method that becomes wider.

FIG. 3 is a graph showing the generated pH value fluctuation of the alkali ion water purifier according to the first embodiment of the present invention.

As shown in FIG. 3, there is provided a control system in which the boundary value of the flow rate section becomes a geometric progression value from the low flow rate area to the high flow rate area. It can be seen that the fluctuation of the generated pH value is small.

As described above, according to the alkali ion water conditioner of the first embodiment, even when the flow rate fluctuates, the boundary value of the flow rate section in the voltage control applied to the electrolytic cell is changed from a low flow rate range to a high flow rate range. As a result, the generated pH value can be stabilized by a control method that becomes a geometric progression value.

[0030]

As is apparent from the above description, the present invention can be applied to the case where the flow rate range of the flow rate section in the voltage control applied to the electrolytic cell is changed from a low flow rate range to a high flow rate range even when the flow rate fluctuates. Since the alkali ion water conditioner is provided with an increasing control system, the generated pH value can be stabilized, and the effect is great.
