2. Description of the Related Art In general, this type of electrolyzed ionized water generating device includes an electrolytic cell having an anode and a cathode respectively disposed in an anode chamber and a cathode chamber separated by an ion exchange membrane. The water continuously supplied to this electrolytic layer is electrolyzed by the electrolytic voltage applied to the anode and cathode, and acidic ionized water containing a large amount of anions flows from the anode chamber and from the cathode chamber. BACKGROUND ART Continuous electrolytic ionized water generators are known that are capable of producing alkaline ionized water containing a large amount of cations.

In addition, in order to remove impurities from the surfaces of the anode and cathode to clean them, there is also known a device equipped with a switching means that reverses the polarity of the voltage applied to the anode and cathode. . In this device, if there is no water in the electrolytic layer, the surface of the positive electrode etc. cannot be cleaned even if the polarity is reversed, so a means for detecting the presence of water in the electrolytic layer is provided. ing.

[0004] Furthermore, conventionally, tap water from which free chlorine has been removed is supplied to the electrolytic cell through a filter containing activated carbon. The efficiency of free chlorine removal of the activated carbon in this filter deteriorates with use.

[Problems to be Solved by the Invention] By the way, in conventional systems that apply an electrolytic voltage when the water pressure of tap water is applied, it is detected whether or not this water pressure is appropriate for the generation device. Do not mean. For this reason, for example, if the water pressure is too low, the pH of the ionized water taken out from the electrolytic cell becomes abnormally high because the water flow rate is low, making it unsuitable for drinking. The current flowing through the electrodes could become abnormally large, potentially causing the electrolytic cell to overheat. If the water pressure is too high,
The large flow rate of water reduces electrolysis efficiency, and there is a risk of water leakage or disconnection at the connection between the filter cartridge, which filters the tap water supplied to the electrolytic cell, and the main body of the generator. be.

[0006] This invention eliminates the above-mentioned conventional problems, and applies the electrolysis voltage when the water pressure of tap water supplied to the generator is within a set appropriate range, and when it is outside the appropriate range, electrolysis is applied. It is designed to issue an alarm without applying any voltage. When this water pressure is within the appropriate range, water is being supplied to the electrolytic cell, and therefore it can be considered that there is water in the electrolytic cell, and the water pressure within the appropriate range is virtually zero. Even when the water supplied to the electrolytic cell is stopped and drained, water remains in the electrolytic cell during the time required for this draining. In this way, by detecting that the water pressure is within the appropriate range, the presence of water in the electrolytic cell is indirectly detected, and when this is detected, the reverse voltage explained in the conventional example is applied. It can also be done. When the above-mentioned water pressure is within the appropriate range, tap water is being supplied to the electrolytic cell, so the time during which this water pressure is within the appropriate range is integrated, and when this reaches the set value, it is displayed, and the filter explained in the conventional example It is also possible to encourage the exchange of

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of the main parts of a continuous electrolytic ionized water generating device, and some of the configuration is omitted to make it easier to understand the content of the invention. FIG. 2 schematically shows the vicinity of the electrolytic cell of this electrolytic ionized water generating device. FIG. 3 schematically shows the electric circuit system of this electrolytic ionized water generating device.

In the figure, reference numeral 1 denotes an electrolytic cell, which has an anode chamber 3 and a cathode chamber 4, which are separated by an ion exchange membrane 2, and an anode 5 and a cathode 6 respectively disposed therein. The water supplied to the electrolytic cell 1 (arrows indicate the direction in which water flows) is electrolyzed by the electrolytic voltage applied to the anode 5 and the cathode 6, and acidic ionized water flows from the anode chamber 3. Also, alkaline ionized water is obtained from the cathode chamber 4. The electrolysis voltage is applied to the anode 5 and the cathode 6 from the electrolysis power supply circuit 7. Reference numeral 8 denotes a well-known pressure sensor composed of a piezoresistor, which will be described later, and is provided in a drain chamber 18 to which tap water is supplied, and outputs a voltage proportional to the water pressure of the tap water. This output voltage is input to the pressure determination circuit 9, and it is determined whether the water pressure is substantially zero or within a set appropriate range. The output of this pressure determination circuit 9 is input to the electrolysis control circuit 26.

This electrolysis control circuit 26 will be explained in more detail later, but the electrolysis power supply circuit 7 is controlled by an output signal from the pressure determination circuit 9 indicating that the water pressure is within a proper range, and the electrolysis tank is started. Electrolytic voltage is applied to electrodes 5 and 6 of No. 1. If an output signal indicating that the water pressure is substantially zero is input from the pressure determination circuit 9, the electrolytic voltage will not be ignited. When the output signal from the pressure determination circuit 9 indicates that the water pressure is not substantially zero and is outside the appropriate range,
At the same time as stopping the application of the electrolytic voltage, an operating current is supplied to the warning buzzer 37 to give a quick warning that the water pressure is too low or too high. This alarm is triggered by the pressure determination circuit 9. It is also emitted by light emitting diodes for warning indications.

Reference numeral 10 denotes a relay having contacts 11 and 12, and the figure shows the contacts being switched to a non-energized state. The relay 10 is controlled to be energized or de-energized by the control circuit 26. The control circuit 26 also controls the power supply circuit 7 as described above, and when an output indicating that the water pressure is within the appropriate range is obtained from the pressure determination circuit 9, the control circuit 26 controls the electrodes 5 and 6 as described above.
Supplies electric current for electrolysis. An integrating circuit 713 is connected to this control circuit 26, and the time during which an output indicating that the water pressure is within an appropriate range from the pressure determining circuit 9 is obtained is integrated.

This integrated value is stored in the memory circuit 30 and continuously integrated even when the output from the pressure determination circuit 9 indicating that the water pressure is within the appropriate range is interrupted. In the control circuit 26, when this integrated value exceeds the set value and the output indicating that the water pressure is within the appropriate range from the detection circuit 9 is interrupted, for example, the water supply to the generator is stopped. Sometimes, the above-mentioned operation is carried out for a time determined by a timer (not shown) in the control circuit 26 (this time is set approximately equal to the time from when the water supply stops until the water in the electrolytic cell 1 is discharged). An excitation current flows through the relay 10, and voltages of opposite polarity are applied to the anode 5 and the cathode 6 during this time. After this predetermined time has elapsed, the power supply circuit 7
The voltage applied to the electrodes 5 and 6 is also cut off.

As shown in FIG. 2, the electrolytic cell 1 has a drain chamber 1 connected to a pipe 14 connected to a tap water faucet.
5. Tap water is supplied through a filter cartridge 17 containing antibacterial granular activated carbon 16, a drain chamber 18, and further through a constant flow valve 19 and a calcium addition tube 20 connected in parallel. Reference numerals 21 and 22 are drain valves (drain ball valves), which are connected between the drain chambers 15 and 18 by the water pressure of the tap water supplied as described above.
and the water pipe 23 through which the waste water from the anode chamber 3 flows. When the aforementioned faucet is closed and the water pressure becomes essentially zero,
The drain valves 21 and 22 are opened, and the electrolytic cell 1, filter
Water in the cartridge 17, constant flow valve 19, calcium addition tube 20, and drain chambers 15 and 18 is drained through a drain pipe 23.

The filter cartridge 17 is for removing free chlorine from tap water, and has been conventionally used in this type of electrolytic ion water generation apparatus. The constant flow valve 19 controls the flow rate characteristics due to changes in the water supply pressure of hydraulic water and enables stable electrolysis, and has been used conventionally. The calcium addition cylinder 20 controls the elution of calcium, increases the calcium concentration of the water supplied to the electrolytic cell 1, and improves the electrolysis efficiency, and has been used conventionally.

As shown in FIG. 3, the electrolysis power supply circuit 7 is supplied with DC power from a commercial AC power supply 24 via an appropriate fuse (not shown) and a rectification/smoothing circuit 25. It is converted into a voltage suitable for electrolysis in the power supply circuit 7. This power supply circuit 7 is controlled by the electrolysis control circuit 26, and as described above, the applied voltage for electrolysis is controlled to open and close, or the voltage for electrolysis is selected. DC power is also supplied from the rectification/smoothing circuit 25 to a control circuit power supply circuit 27 . This power supply circuit 27 converts the supplied DC power into a voltage suitable for the electrolysis control circuit 26, etc., and supplies it to the pressure determination circuit 9, relay 10, integration timer 13, and electrolysis control circuit 26. It is also supplied to the load detection circuit 28, filter integration timer 29, etc.

The electrolysis control circuit 26 includes a filter integration timer 29, an integration timer 13, and a memory circuit 30.
It is also composed of a microcomputer. A level changeover switch 31 is connected to this electrolysis control circuit 26, and by operating this switch 31, the electrolysis voltage applied from the power supply circuit 7 to the electrodes 5, 6 via the control circuit 26 is varied, and the electrolysis The pH level of the acidic ionized water and alkaline ionized water obtained by this method can be varied. This PH level is displayed by a plurality of light emitting diodes (not shown) connected to the electrolysis control circuit 26.

[0020] In the electrolyzed ionized water generator as described above,
When the power supply current from the AC power supply 24 is supplied to the power supply circuits 7 and 27, a voltage is applied from the power supply circuit 27 to the light emitting diode 32 for power display connected to the output side of the power supply circuit 27, which lights up and at the same time The power supply voltage is also applied to the electrolysis control circuit 26 etc. as shown in FIG. In this way, the power supply circuits 7 and 2
When the tap water faucet is closed while the power supply current is supplied to 7, the voltage output from the pressure sensor 8 to the pressure judgment circuit 9 is substantially zero, and the water pressure is output from the judgment circuit 9. The electrolytic control circuit 26 receives a signal indicating that it is substantially zero.
The electrolytic voltage is not applied to the electrodes 5 and 6 from the power supply circuit 7.

[0021] With the power supply current being supplied to the power supply circuits 7 and 27 in this way, open the tap water faucet described above,
When tap water is supplied to the electrolyzer 1, if the water pressure at that time is within the appropriate range, the pressure determination circuit 9 determines this based on the output of the pressure sensor 8, and the electrolysis control circuit 26 is informed that the water pressure is within the appropriate range. Outputs a signal indicating that Based on the output of the pressure determination circuit 9, the electrolysis control circuit 26 supplies a control signal to apply an electrolysis voltage to the power supply circuit 7, and the voltage set by the switch 31 is applied to the electrode 5 from the power supply circuit 7 as the electrolysis voltage. , 6.

When the water pressure of the tap water supplied as described above is not substantially zero and is outside the appropriate range, the electrolytic voltage is not applied as described above, and the operating current is supplied to the warning buzzer 37, A light emitting diode 38 lights up to warn that the water pressure is too low or too high.

When the tap water is turned off as described above and tap water with a water pressure within the appropriate range is supplied to the electrolytic cell 1, the pressure determination circuit 9 outputs an output indicating that the water pressure is within the appropriate range. is supplied to the electrolysis control circuit 26, and the time during which this output is supplied is accumulated in the integration timer 13 as described above. When this integrated value exceeds the set value, if you close the tap water faucet and stop the tap water, a voltage of opposite polarity is applied to the electrodes 5 and 6 as described above, and this voltage is applied. At times, the light emitting diode 33 for displaying the cleaning mode is lit by the output of the electrolysis control circuit 26 to indicate that the surfaces of the electrodes 5 and 6 are being cleaned. The integrated value of the integration timer 13 is stored in the memory circuit 30 via the control circuit 26. Incidentally, this memory circuit 30 is a nonvolatile RAM, and stores data even if the power supply current to the microcomputer is cut off.

As mentioned above, when tap water with a water pressure within the appropriate range is supplied to the electrolytic cell 1, the electrolytic ionized water generating device starts generating ionized water, and the electrolytic control circuit 26 emits light to indicate the application of electrolytic voltage. An instruction signal is output that causes the diode 34 to emit light and causes the filter integration timer 29 to integrate time. The integrated value of the filter integration timer 29 is stored in the memory circuit 30 via the electrolysis control circuit 26. When the integrated value of the timer 29 reaches a set value, that is, when the expiration date of the activated carbon 16 in the filter cartridge 17 has come, the light emitting diode 35 lights up, prompting the cartridge 17 to be replaced.

During such ionized water generation operation, if the temperature of the electrolyzed ionized water generation device becomes higher than the set value due to long-term use, the overload detection circuit 28 operates, and this operation causes the overload display The light emitting diode 36 is turned on, and the electrolysis current supplied from the power supply circuit 7 to the electrodes 5 and 6 via the electrolysis control circuit 26 is cut off.

As described above, since the integrated value of the integrated timer 13 is stored in the memory circuit 30, the water supply to this generator is stopped by closing the tap water faucet as described above, and the output from the pressure sensor 8 is Even if water is supplied to this generation device again after water is no longer obtained, when an output indicating that the water pressure is within the appropriate range is obtained from the pressure determination circuit 9, the information stored up to that point will be returned. You can add a new total to the previously accumulated value.

Furthermore, since the integrated value of the filter integration timer 29 is also stored in the memory circuit 30, the output can be obtained from the pressure sensor 8 by closing the tap water faucet and stopping the water supply to the generator as described above. Even if tap water is supplied to this generation device again after the water has run out, when an output indicating that the water pressure is within the appropriate range is obtained from the pressure determination circuit 9, the memory up to that point will be The accumulated value can be newly integrated.

As mentioned above, when the tap water supplied to this generator is stopped and no output is obtained from the pressure sensor 8, if the integrated value of the integrated timer 13 exceeds the set value, As described above, the electrolytic control circuit 26 supplies the exciting current to the relay 10, and the contacts 11, 1
2 is inverted, a voltage of opposite polarity is applied to the electrodes 5 and 6, and this state continues for a predetermined time by the timer provided in the electrolysis control circuit 26. When tap water is supplied to this generation device in a state where pressure is applied, the electrolysis control circuit 26 from the pressure determination circuit 9
The excitation current to the relay 10 is interrupted by the output indicating that the water pressure is within the appropriate range, and the electrodes 5,
6 is applied with a positive voltage for electrolysis.

In this way, even when a voltage of opposite polarity is applied, a positive voltage is applied by supplying tap water, and acidic ion water flows from the anode chamber 3 and from the cathode chamber 4. Alkaline ionized water can be obtained from the anode chamber 3 and cathode chamber 4, but for a short time after the applied voltage is switched from reverse polarity to positive polarity as described above, acidic ion water is obtained from the anode chamber 3 and cathode chamber 4. Water mixed with alkaline ionized water is obtained. During this period, an operating current is supplied from the electrolysis control circuit 26 to the warning buzzer 37 in order to warn the user not to drink the mixed water. In addition, by applying a voltage of opposite polarity to the electrodes 5 and 6 as described above, not only the surfaces of the electrodes 5 and 6 are cleaned, but also the ion exchange efficiency is increased and the water intake path on the cathode chamber 4 side is cleaned. It can also be sterilized.

FIG. 4 shows details of the mounting state of the pressure sensor 8 provided in the drain chamber 18 as described above. In FIG. 4, reference numeral 40 indicates an opening formed in a wall 41 of the train chamber 18, and this opening 41 is covered with a diaphragm 42 made of rubber. 43 is a pressure introduction pipe, which is attached to the wall 41 with bolts and nuts (not shown). The wall 4 is located near the peripheral edge of the diaphragm 42.
1 and the pressure introduction pipe 43, and are fixed. The protruding tube part of the pressure sensor 8 is fitted near the lower end of this pressure introduction pipe 43, and the O-ring 4 is deformed by tightening a tightening screw 44 screwed into the vicinity of the lower end of the pressure introduction pipe 43.
5, the pressure introduction pipe 43 and the above-mentioned pipe portion of the pressure sensor 8 are connected in an airtight state.

[0031] The pressure introduction pipe 43 and the diaphragm 42
A sealed chamber 46 is formed by the pressure sensor 8 and the pipe portion of the pressure sensor 8, and this sealed chamber 46 is filled with air (or liquid). When the water pressure in the drain chamber 18 changes, the pressure in the sealed chamber 46 also changes accordingly, and a voltage corresponding to this pressure is output from the pressure sensor 8. For example, in the case of a diffusion type semiconductor pressure sensor, the pressure sensor 8 has piezoresistors R1 to R4 connected in a Wheatstone bridge, as shown in FIG. Piezo resistance R1
A constant current source 4 is connected to the connection point of R2 and the connection point of R3 and R4.
By supplying a constant current from 7, a voltage proportional to the pressure described above is output to the connection point between piezoresistors R1 and R4 and the connection point between R2 and R3. FIG. 6 is a characteristic diagram of the pressure sensor 8 showing the output voltage of the pressure sensor 8 with respect to the above-mentioned pressure.

The position where the pressure sensor 8 is installed is shown in FIG.
If the constant flow valve 19 is not provided, the side where acidic ion water or alkaline ion water is taken out from the electrolytic cell 1 may be used as long as it does not pass through the constant flow valve 19 such as the drain chamber 18. A tube may also be used.

[0033] In the above embodiment, the electrode Although the voltages applied to 5 and 6 were reversed in polarity, when the integrated value of the integration timer 13 reached the set value (there was an output from the pressure judgment circuit 9 indicating that the water pressure was within the appropriate range). However, a voltage of opposite polarity may be applied, and the voltage may be returned to positive polarity after a period set by the electrolysis control circuit 26.

[0034] In the above embodiment, the electrode Although the voltages applied to 5 and 6 have been reversed in polarity, an output from the pressure determination circuit 9 indicating that the water pressure is within the appropriate range is obtained, or within a predetermined period after this output is interrupted. For example, the presence of water in the electrolytic cell 1 may be indirectly detected, and on condition that this is detected, a voltage of opposite polarity may be manually applied. Note that even if the water pressure of the tap water supplied to this device is within the set appropriate range, the water pressure may change abnormally due to water leakage or clogging of the pipe line. In order to detect this and issue an alarm, the output voltage of the pressure sensor proportional to the water pressure may be stored in a memory circuit and compared with the newly inputted output voltage of the pressure sensor.

And issue a warning. This prevents the device from operating when the water pressure is too low and extracting alkaline ionized water with a high pH that is not suitable for drinking, or causing the electrolytic cell temperature to become abnormally high. In addition, this device will not operate even when the water pressure is too high, resulting in a decrease in electrolysis efficiency or water leakage at the joint of the filter cartridge attached to this device.

[0037] Whether water is in the electrolytic cell or not is indirectly detected by the output of the determination circuit indicating that the water pressure is within an appropriate range, and it is detected that water is in the electrolytic cell. The electrode surface can be cleaned by allowing the voltage to have the opposite polarity when the voltage is applied.

[0038] Means is provided for integrating the time during which it is detected that tap water is being supplied to the electrolytic cell by the output of the determination circuit indicating that the water pressure is within the appropriate range, and the cumulative time is By displaying this as the expiry date of the filter when it reaches a set value, it is also possible to know the lifespan of the filter.
