  The present invention relates to an electrolyzed water generating apparatus.

  As one type of electrolyzed water generator, a flow rate adjustment valve for adjusting the supply flow rate of raw water for preparing electrolyzed water or electrolyzed water to be supplied to an electrolyzer, and supply flow rate or electrolyzed water for electrolyzed water A flow rate detecting means for detecting the raw water to be supplied, and controlling the flow rate adjusting valve based on a flow rate detection signal output from the flow rate detecting means to preset a supply flow rate of the electrolyzed water supplied to the electrolytic cell There is an electrolyzed water generating device that adjusts the supplied flow rate.

As a means for protecting the flow rate adjusting valve, when the valve is fully open and fully closed, a limiter inside the flow rate adjusting valve detects this and energizes the motor drive unit.
Japanese Patent Laid-Open No. 10-57961

  By the way, in the electrolyzed water generating device of this type, when the flow rate adjustment valve falls into a malfunction during electrolysis, the supply flow rate of the electrolyzed water supplied into the electrolytic cell cannot be adjusted. Electrolysis of water to be electrolyzed under the set electrolysis conditions becomes impossible, and electrolyzed water having the set characteristics cannot be generated. For this reason, when an operation failure occurs in the flow rate adjustment valve during the electrolysis operation of the electrolyzed water generating device of this type, a countermeasure against this is required.

  As a first cause of the malfunction of the flow rate adjusting valve, there can be mentioned a case where a motor driving unit constituting the flow rate adjusting valve fails. In this case, the motor that operates the valve unit does not drive, the valve unit cannot operate, and exhibits a fully closed state or a fully open state, and the flow rate of electrolyzed water supplied into the electrolytic cell is zero, or The maximum flow rate allowed by the flow rate adjustment valve becomes impossible to adjust the supply flow rate of the electrolyzed water supplied into the electrolytic cell.

  As a second cause of the malfunction of the flow rate adjusting valve, there can be mentioned a case where a force is applied to the valve unit from the outside, for example, foreign matter is mixed into the valve unit constituting the flow rate adjusting valve. In this case, the motor is in a driving state, but the valve part cannot be opened or closed.However, when the external force applied to the valve part is removed, for example, foreign matter mixed in the valve part is discharged. The operation of the flow rate adjusting valve is restored.

  Therefore, the object of the present invention is to accurately confirm the cause of the malfunction of the flow rate adjustment valve during the electrolysis operation of the electrolyzed water generation device of the type, and to cause each of the above causes in the electrolysis operation of the electrolyzed water generation device. In response to this, it is to cope with the malfunction of the flow rate adjustment valve.

  The present invention relates to an electrolytic operation method for an electrolyzed water generating apparatus. The electrolyzed water generating apparatus to which the present invention is subjected to electrolysis operation includes an electrolyzed water to be supplied to an electrolyzer or a flow rate adjusting valve for adjusting a supply flow rate of raw water for preparing electrolyzed water, and electrolyzed water or electrolyzed water Electrolyzed water to be supplied to the electrolyzer is provided with flow rate detection means for detecting the supply flow rate of raw water for preparing water, and controls the flow rate adjustment valve based on a flow rate detection signal output from the flow rate detection means This is an electrolyzed water generating device of a type in which the supply flow rate is adjusted to a preset supply flow rate.

  Therefore, the first electrolytic operation method according to the present invention stops the electrolytic operation or gives a warning when an abnormal flow rate change preset in the supply flow rate detected by the flow rate detecting means is recognized. It is characterized by generating. In the electrolytic operation method, the abnormal flow rate change in the supply flow rate of raw water for preparing electrolyzed water or electrolyzed water means that the supply flow rate is constant and the supply flow rate is constant, or the flow rate of the supply flow rate It is assumed that the change is within a preset range and the supply flow rate approximates to be constant. Further, the case where the supply flow rate is not changed and the supply flow rate is constant includes the case where the supply flow rate is zero.

  Further, the second electrolytic operation method according to the present invention performs the electrolytic operation when the change in the flow rate of the supply flow detected by the flow rate detection means is within a preset range and the supply flow rate is approximately constant. The electrolysis operation is temporarily stopped and the electrolysis operation is resumed after a predetermined time has elapsed. In the electrolysis operation method, the predetermined time for stopping the electrolysis operation is a time until the heating temperature of the motor driving unit due to the driving of the flow rate adjusting valve is lowered to a normal temperature.

  Further, a third electrolysis operation method according to the present invention is an electrolyzed water generating apparatus of the above-described type, comprising an electrolyzed water generating apparatus provided with temperature detecting means for detecting the temperature of a motor driving unit constituting the flow rate adjusting valve. When the temperature output from the temperature detecting means is within a preset heating temperature range, the electrolysis operation is temporarily stopped and then the electrolysis operation is resumed. To do.

  In the electrolytic operation method, the time for temporarily stopping the electrolytic operation can be set to a preset time until the heating temperature of the motor drive unit due to the driving of the flow rate adjusting valve decreases to a normal temperature. Further, in the electrolytic operation method, when the temperature of the motor drive unit detected when a predetermined time has elapsed after temporarily stopping the electrolytic operation, the electrolytic operation is restarted when the temperature is reduced to a normal temperature, When the temperature of the motor drive unit is not lowered to a normal temperature, the electrolysis operation can be completely stopped.

  In the first electrolytic operation method according to the present invention, the malfunction of the flow rate adjustment valve is caused by an abnormal flow rate change of the electrolyzed water or raw water for preparing the electrolyzed water, for example, the supply flow rate does not change. Confirm the case of constant (including zero) or the case where the change in the supply flow rate is within a preset range and the supply flow rate is close to a constant, etc. Like to stop. According to such means for confirming the malfunction of the flow regulating valve, this can be confirmed in synchronization with the occurrence of the malfunction of the flow regulating valve, so that the damage caused by the electrolysis operation deviating from the set electrolysis conditions is minimized. There is an advantage that it can be limited.

  Further, in the second electrolysis operation method according to the present invention, the malfunction of the flow rate adjusting valve may be caused by an abnormal flow rate change of the water to be electrolyzed or raw water for preparing the water to be electrolyzed, for example, the supply flow rate is unchanged. When the flow rate is constant or when the change in flow rate of the supply flow rate is within a preset range and the supply flow rate approximates to a certain level, etc., the electrolysis operation is temporarily stopped and the electrolysis is performed after a preset time has elapsed. Driving is resumed. The predetermined time for temporarily stopping the electrolysis operation in this case is a time until the heating temperature resulting from the driving of the motor driving unit constituting the flow rate adjusting valve is lowered to a normal temperature. Thereby, there is an advantage that the electrolysis operation can be temporarily stopped when an external force is applied to the valve portion constituting the flow rate adjusting valve and the electrolysis operation can be resumed when the external force disappears. .

  Further, in the third electrolytic operation method according to the present invention, the motor drive unit detects that the valve part constituting the flow rate adjusting valve has malfunctioned and that the malfunction has been resolved and has returned to the normal state. By directly detecting the temperature of the battery, the electrolytic operation is temporarily stopped when the valve section is malfunctioning, and the electrolytic operation is resumed when the malfunction is resolved and the normal state is restored. Yes. Thereby, there exists an advantage that the stop of the electrolysis operation when the external force with respect to the valve part of a flow control valve is given and the restart of the electrolysis operation when the external force disappears can be performed accurately. Further, in the electrolytic operation method, when the electrolytic operation is resumed, the temperature of the motor drive unit can be detected again, and the presence or absence of malfunction of the valve part of the flow rate adjustment valve can be confirmed again. Thus, when the malfunction of the valve portion is not resolved even after a predetermined time has elapsed after the electrolysis operation is temporarily stopped, the resumption of the electrolysis operation can be stopped.

  The present invention relates to an electrolysis operation of an electrolyzed water generating apparatus. The electrolyzed water generating apparatus to which the present invention is subjected to electrolysis operation includes an electrolyzed water supplied to an electrolyzer or a flow rate adjusting valve for adjusting a supply flow rate of raw water for preparing electrolyzed water, and electrolyzed water or electrolyzed water Electrolyzed water supplied to the electrolyzer is provided with flow rate detection means for detecting the supply flow rate of raw water for preparing water, and controls the flow rate adjustment valve based on a flow rate detection signal detected from the flow rate detection means. This is an electrolyzed water generating device that adjusts the supply flow rate to a preset supply flow rate. The electrolytic operation method according to the present invention assumes that a malfunction occurs in the flow rate adjustment valve.

  The raw water for preparing the electrolyzed water is prepared by mixing with high-concentration salt water to prepare the electrolyzed water that is dilute salt water. A very small amount and a substantially constant amount are mixed. Therefore, adjusting the supply flow rate of raw water is equivalent to adjusting the supply flow rate of the electrolyzed water, and detecting the supply flow rate of the raw water detects the supply flow rate of the electrolyzed water. It is equivalent to doing.

  FIG. 1 shows an example of an electrolyzed water generating apparatus that is an object of electrolysis operation according to the present invention. The electrolyzed water generating device is a diaphragm-type electrolyzed water generating device that uses a dilute aqueous solution of salt as electrolyzed water. The electrolyzed water generating device includes a diaphragm-type electrolytic cell 10, an electrolyzed water preparation mechanism 20, and an electrolysis operation. A control device 30 for controlling is provided.

  The electrolytic cell 10 is known per se, and the inside of the cell body 11 is divided into a pair of compartments by a diaphragm 12, and each compartment is provided with a pair of electrodes 13a and 13b. It is formed in electrolysis chambers R1 and R2. In the electrolytic cell 10, a branch pipe section of a water supply pipe 14 for supplying water to be electrolyzed is connected to an upstream portion of each electrolytic chamber R 1, R 2, and a downstream portion of each electrolytic chamber R 1, R 2. The outflow pipes 15a and 15b for allowing the electrolytically generated water to flow out are connected. The electrodes 13a and 13b in the electrolysis chambers R1 and R2 are connected to a power source 31, respectively. A constant voltage set from the power source 31 is applied during the electrolysis operation.

  The electrolyzed water preparation mechanism 20 includes a concentrated salt water tank 21 containing saturated saline, a salt water supply line 22 connected to the concentrated salt water tank 21 and the water supply line 14, and a salt water supply line 22. A pump 23 and a check valve 24 are provided. One end of the concentrated salt water supply pipe 21 extends to an intermediate portion in the concentrated salt water tank 21. The pump 23 is a metering pump driven by an electric motor, and functions to pump the saturated saline in the concentrated salt water tank 21 through the check valve 24 and into the water supply line 14 when driven. The saturated saline solution pumped into the water supply line 14 is mixed with raw water such as tap water flowing in the water supply line 14 with the flow rate controlled to prepare a diluted saline solution having a set concentration. The prepared dilute saline solution is supplied as electrolyzed water to the electrolysis chambers R1 and R2 through the branch pipe sections of the water supply pipe 14.

  In the electrolyzed water generating apparatus, a water supply valve 16 a, a flow rate sensor 16 b, and a flow rate adjustment valve 16 c are interposed in a portion upstream of the connection portion of the salt water supply conduit 22 in the water supply conduit 14. The water supply valve 16 a is a normally closed electromagnetic on-off valve, and is controlled to be opened and closed by the control device 30. The water supply valve 16a is opened when the electrolyzed water generating apparatus is electrolyzed, introduces raw water into the water supply line 14, and is closed when the electrolysis operation is stopped. Stop introducing raw water into The flow rate sensor 16b is a flow rate detection unit that detects the flow rate of the raw water flowing in the water supply pipe 14, and outputs the detected flow rate to the control device 30 as a detection signal.

  The control device 30 operates the flow rate adjustment valve 16c based on the detection signal output from the flow rate sensor 16b, and adjusts the flow rate of the raw water flowing in the water supply conduit 14 to the set flow rate, and the salt of the electrolyzed water. Control the density to the set density. The flow rate adjusting valve 16c is an automatic flow rate adjusting valve that uses an electric motor as a drive source, and the control device drives the electric motor based on a flow rate detection signal output from the flow rate sensor, and the flow rate adjusting valve 16c. The flow rate to the downstream side of the raw water is adjusted by repeatedly performing the fully open and fully closed state of the valve portion constituting the.

  Further, in the electrolyzed water generating apparatus, a current sensor 32 for detecting an electrolysis current in the electrolytic cell 10 during electrolysis operation is provided on one of the connection circuits connecting the power supply 31 and the electrodes 13a and 13b. The sensor 32 outputs the detected electrolytic current value to the control device 30 as a detection signal. The control device 30 controls the drive of the pump 23 based on the detection signal output from the current sensor 32, adjusts the discharge flow rate of the concentrated salt water discharged from the pump 23, and supplies the electrolyzed water together with the adjusted raw water. Adjust the salt concentration to the set concentration.

  The electrolyzing operation of the electrolyzed water generating apparatus is performed by the above-described control by the control device 30, and diaphragm electrolysis is performed in the electrolyzer 10 under certain electrolysis conditions set, and in each electrolysis chamber R1, R2. Electrolytically generated acidic water and electrolytically generated alkaline water having the set characteristics are respectively generated. Therefore, the electrolytic operation method according to the present invention addresses the malfunction of the flow rate adjusting valve 16c on the assumption that a malfunction occurs in the flow rate regulating valve 16c.

  The first cause of the malfunction in the flow rate adjusting valve 16c can be a case where the motor driving unit constituting the flow rate adjusting valve 16c fails. In this case, the motor that operates the valve unit is not driven, the valve unit cannot operate, and the fully closed state or the fully open state is exhibited. It falls into a state where it cannot be adjusted. The second cause of the malfunction of the flow rate adjusting valve 16c is a case where a force is applied to the valve portion from the outside, for example, foreign matter is mixed into the valve portion constituting the flow rate adjusting valve 16c. it can. In this case, the motor is in a driving state, but the valve part cannot be opened and closed, and when the external force on the valve part is removed, for example, foreign matter mixed in the valve part is discharged, The operation of the flow rate adjusting valve 16c returns to normal.

  In the first electrolytic operation method according to the present invention, the malfunction of the flow rate adjusting valve 16c is caused by an abnormal flow rate change of raw water for preparing the electrolyzed water or the electrolyzed water, for example, the supply flow rate without any change in the supply flow rate. Is confirmed (including the case of zero), or when the change in the supply flow rate is within a preset range and the supply flow rate approximates to a constant value, etc. The operation is stopped. In the embodiment according to the present invention, a flow rate sensor 16b that detects the supply flow rate of raw water is adopted, and a flow rate adjustment valve 16c that adjusts the supply flow rate of raw water is adopted. According to such a confirmation means for confirming the malfunction of the flow regulating valve 16c, the malfunction condition of the flow regulating valve 16c can be confirmed in synchronism with the occurrence of malfunction, so that it deviates from the set electrolysis conditions. There is an advantage that damage caused by electrolytic operation can be minimized.

  In the first electrolysis method according to the present invention, the motor is stopped due to a failure of the motor drive unit constituting the flow rate adjustment valve 16c, and the valve unit constituting the flow rate adjustment valve 16c is fully closed or fully opened. Assumes that. In this case, the supply flow rate of the raw water appears as zero or an excessive constant flow rate.

  Further, in the second electrolytic operation method according to the present invention, the malfunction of the flow rate adjustment valve 16c is caused by an abnormal flow rate change of the raw water, for example, when the supply flow rate is constant without changing the supply flow rate of the raw water, Confirm that the change in supply flow rate is within a preset range and the supply flow rate is close to a certain level, etc., and temporarily stop the electrolysis operation, and resume the electrolysis operation after a preset time. Yes. The predetermined time for stopping the electrolysis operation in this case is a time until the heating temperature of the driving unit due to the driving of the motor driving unit constituting the flow rate adjusting valve 16c decreases to a normal temperature. Thereby, there is an advantage that the electrolysis operation can be temporarily stopped when an external force is applied to the valve portion of the flow rate adjusting valve 16c and the electrolysis operation can be resumed when the external force disappears.

  The second electrolytic operation method according to the present invention assumes that foreign matter or the like is mixed into the valve portion of the flow rate adjusting valve 16c and the valve portion is in a malfunctioning state. In this case, the motor of the motor driving unit continues to be driven, and the motor driving unit is heated to gradually increase the temperature. For this reason, if the heating temperature of the motor drive unit is reduced to a normal temperature, it is determined that the external force (mixing of foreign matter, etc.) on the valve unit has been eliminated, and the heating temperature of the motor drive unit is reduced to a normal temperature. Knowing the time in advance, this time is set as the predetermined time.

  Further, in the third electrolytic operation method according to the present invention, the fact that the valve portion constituting the flow rate adjustment valve 16c has malfunctioned and that the malfunction has been resolved and the motor has returned to the normal state is driven by a motor. This is done by directly detecting the temperature of the part, and temporarily stops the electrolysis operation when the valve section becomes defective and restarts the electrolysis operation when the malfunction is resolved and returns to the normal state. ing. Thereby, the temporary stop of the electrolysis operation when an external force is applied to the valve portion of the flow rate adjusting valve 16c and the restart of the electrolysis operation when the external force disappears can be accurately performed.

  Similarly to the second electrolytic operation method, the electrolytic operation method assumes that foreign matter or the like is mixed into the valve portion of the flow rate adjusting valve 16c and the valve portion is in a malfunctioning state. Then, there exists an advantage that generation | occurrence | production of the malfunctioning of the flow regulating valve 16c can be confirmed by detecting the temperature of a motor drive part directly.

  The electrolysis operation of the electrolyzed water generating device is controlled by the control device 30. In particular, when a malfunction occurs in the flow rate adjustment valve 16c, the control device 30 implements each electrolysis operation method according to the present invention. The electrolytic operation control program is executed based on the flowcharts shown in FIGS.

  The flowchart shown in FIG. 2 is a flowchart for executing an electrolysis operation control program for carrying out the first electrolysis operation method according to the present invention, and the control device 30 is a step in the middle of the electrolysis operation of the electrolyzed water generator. If it is determined at 101 that the flow rate of the raw water detected by the flow rate sensor 16b has an abnormal flow rate change such that the flow rate is constant or close to constant including zero, the electrolytic operation is performed at step 102. If it is determined that there is no abnormal flow rate change, the electrolytic operation is continued in step 103 and the control program is returned to step 101.

  The electrolysis operation control by the control device 30 assumes that the motor is stopped due to a failure of the motor drive unit constituting the flow rate adjustment valve 16c, and the valve unit constituting the flow rate adjustment valve 16c is fully closed or fully opened. is doing. For this reason, when such a malfunction occurs in the flow regulating valve 16c, the malfunction of the flow regulating valve 16c is confirmed based on the abnormal state of the flow rate change of the raw water. Since the operation failure can be confirmed in synchronism with the occurrence of the failure, the damage caused by the electrolytic operation deviating from the set electrolysis conditions can be minimized.

  The flowchart shown in FIG. 3 is a flowchart for executing the electrolysis operation control program for implementing the second electrolysis operation method according to the present invention, and the control device 30 is in the middle of the electrolysis operation of the electrolyzed water generating device. If it is determined in step 201 that the flow rate of the raw water detected by the flow sensor 16b has an abnormal flow rate change such that the flow rate is constant or close to constant including zero, in step 202, The electrolysis operation is temporarily stopped and the electrolysis operation is resumed after a predetermined time has elapsed. After restarting the electrolysis operation, the control device 30 determines again in step 203 whether there is a change in the flow rate of the raw water, and if it is determined that there is an abnormal flow rate change, in step 204 If the electrolysis operation is stopped and the electrolysis operation is terminated and it is determined that there is no abnormal flow rate change, the electrolysis operation is continued in step 205 and the control program is returned to step 201. If it is determined in step 201 that there is no abnormal flow rate change in the raw water supply flow, the control device 30 continues the electrolysis operation in step 205 and returns the control program to step 201.

  The electrolysis operation control by the control device 30 assumes that foreign matter or the like is mixed in the valve portion of the flow rate adjusting valve 16c and the valve portion is in a malfunctioning state. In this case, the motor of the motor drive unit continues to be driven, and the motor drive is heated to gradually increase the temperature. For this reason, if the heating temperature of the motor drive unit is reduced to a normal temperature, it is determined that the external force (mixing of foreign matter, etc.) on the valve unit has been eliminated, and the heating temperature of the motor drive unit is reduced to a normal temperature. The time is measured in advance, and this time is set as the predetermined time. Thereby, the temporary stop of the electrolysis operation when an external force is applied to the valve portion of the flow rate adjusting valve 16c and the restart of the electrolysis operation when the external force disappears can be accurately performed.

  The flowchart shown in FIG. 4 is a flowchart for executing the electrolysis operation control program for implementing the third electrolysis operation method according to the present invention, and the control device 30 is in the middle of the electrolysis operation of the electrolyzed water generating device. In Step 301, the presence or absence of abnormal heating of the motor drive unit is determined. If it is determined that the motor drive unit has abnormal heating, the electrolytic operation is temporarily stopped in Step 302, and after a predetermined time has elapsed, At 303, the presence or absence of abnormal heating of the motor drive unit is determined again. When it is determined in step 303 that the motor drive unit has abnormal heating, the control device 30 stops the electrolysis operation in step 304, and when it is determined that the motor drive unit has no abnormal heating. In Step 305, the electrolytic operation is restarted, and the control program is returned to Step 301. Further, when it is determined in step 301 that the motor drive unit has no abnormal heating, the control device 30 continues the electrolysis operation (step 306) and returns the control program to step 301.

  The electrolysis operation control by the control device 30 assumes that, as in the second electrolysis operation method, foreign matter or the like is mixed into the valve portion of the flow rate adjusting valve 16c, and the valve portion is in a malfunctioning state. The difference from the second electrolysis operation method is that in the electrolysis operation control, the occurrence of malfunction of the flow rate adjustment valve 16c is directly confirmed by detecting the heating state of the motor drive unit resulting therefrom. .
