  As one type of electrolyzed water generating device, an electrolyzed water generating mechanism, a water storage tank that receives electrolyzed water generated by electrolysis operation of the electrolyzed water generating mechanism, and stores the electrolyzed water, and an electrolyzed water generating mechanism There is an electrolyzed water generating device including a control device that controls electrolysis operation. In the electrolyzed water generating device, the user of the electrolyzed water is configured to derive and use a desired amount of electrolyzed water stored in the water storage tank when desired, and also stored in the water storage tank.

JP 2000-5750 A

  In this way, the electrolyzed water generating device of this type automatically supplements the consumed amount of electrolyzed water when a predetermined amount of electrolyzed water stored in the water storage tank is consumed, It can be said that this is an effective electrolyzed water generator. However, when the upper limit water level sensor becomes inoperable due to an abnormal condition such as a failure in the upper limit water level sensor among the water level sensors provided in the water storage tank, the water level detection signal from the lower limit water level sensor The electrolysis generation operation of the electrolyzed water generation mechanism started based on the above cannot be stopped based on the water level detection signal from the upper limit water level sensor, and the electrolyzed water generated by the electrolyzed water generation mechanism is supplied to the water storage tank Will continue indefinitely.

  For this reason, in the electrolyzed water generating device of this type, when an abnormal state occurs in which the upper limit water level sensor does not operate, it is excessive unless the electrolysis operation of the electrolyzed water generating mechanism is stopped by knowing the inoperable state of the upper limit water level sensor. Due to the electrolyzed water supplied to the tank, the electrolyzed water overflows from the water storage tank, and a large amount of electrolyzed water flows out wastefully. The conventional electrolyzed water generating device of this type does not include means for notifying the abnormal state when an abnormal state in which the upper limit water level sensor disposed in the water storage tank does not operate occurs.

  Therefore, the object of the present invention is that the above-described case where the upper limit water level sensor becomes inoperable, assuming that the upper limit water level sensor may fall into an abnormal state where the upper limit water level sensor does not operate in the electrolyzed water generating device of the type. To deal with the problem.

  The present invention relates to an electrolyzed water generating apparatus. An electrolyzed water generating apparatus to which the present invention is applied includes an electrolyzed water generating mechanism, a water storage tank that receives electrolyzed water generated by electrolysis operation of the electrolyzed water generating mechanism, and stores the electrolyzed water, and A control device for controlling the electrolysis operation of the electrolyzed water generation mechanism, and an upper limit water level sensor for detecting an upper limit water level of electrolyzed water to be stored and outputting the water level detection signal to the control device in the water storage tank; It is an electrolyzed water generating device of a type provided with a lower limit water level sensor that detects the lower limit water level of the electrolyzed water to be output and outputs it as a water level detection signal to the control device. The electrolyzed water generating device of the type starts electrolysis operation of the electrolyzed water generating mechanism based on a water level detection signal from the lower limit water level sensor, starts supplying electrolyzed water to the water storage tank, and It functions to stop the electrolysis operation of the electrolyzed water generation mechanism based on the water level detection signal from the upper limit water level sensor and stop the supply of electrolyzed water to the water storage tank.

  Thus, the electrolyzed water generating device according to the present invention includes a flow rate detection sensor that detects the supply flow rate of electrolyzed water supplied to the water storage tank and outputs the flow rate detection signal to the control device. The electrolysis operation of the electrolyzed water generation mechanism started based on the water level detection signal from the lower limit water level sensor, the measured value of the electrolyzed water supply flow rate based on the flow rate detection signal from the flow rate detection sensor is set It stops when it reaches a predetermined flow rate, and functions to stop the supply of electrolytically generated water to the water storage tank.

  In the electrolyzed water generating apparatus according to the present invention, even when electrolyzed water is supplied to the water storage tank by electrolysis operation of the electrolyzed water generating mechanism, the electrolyzed water contained in the water storage tank is derived. In this case, when the derivation of the electrolyzed water from the water storage tank is completed, the control device is configured to use the electrolyzed water based on the flow rate detection signal of the flow rate detection sensor. The measurement value of the supply flow rate can be temporarily canceled and the measurement can be performed so as to restart the measurement of the supply flow rate of the electrolyzed water based on the flow rate detection signal.

  In the electrolyzed water generating apparatus according to the present invention, electrolysis operation of the electrolyzed water generating mechanism is started based on the water level detection signal from the lower limit water level sensor disposed in the water storage tank, and the electrolyzed water generating mechanism generates the electrolyzed water. The electrolyzed water is supplied to the water storage tank and supplemented with the electrolyzed water that is derived from the water storage tank and consumed, but the electrolysis operation of the electrolyzed water generation mechanism is set by the electrolyzed water supplied to the water storage tank. When the predetermined amount is reached, the supply is stopped, and the supply of electrolytically generated water to the storage tank is stopped.

  For this reason, in the electrolyzed water generating apparatus according to the present invention, even when an abnormal condition occurs in the upper limit water level sensor and the sensor becomes inoperable, the supply of electrolyzed water to the water storage tank is not continued. Therefore, the electrolytically generated water in the water storage tank does not fall into an excessive state. In other words, in the electrolyzed water generating apparatus, even when an abnormal state in which the upper limit water level sensor does not operate occurs, the electrolyzed water is not supplied excessively, and the electrolyzed water may overflow from the water storage tank. Without a large amount of electrolyzed water flowing out unnecessarily.

  In the electrolyzed water generating apparatus according to the present invention, even when electrolyzed water is supplied to the water storage tank by the electrolysis operation of the electrolyzed water generating mechanism, the electrolyzed water stored in the water storage tank can be derived and used. It can be constituted as follows. In this case, when the derivation of the electrolyzed water from the storage tank is finished, the control device once cancels the measured value of the electrolyzed water supply flow rate based on the flow rate detection signal, and performs electrolysis based on the flow rate detection signal. It is made to function so that measurement of the supply flow rate of product water may be resumed. Thereby, from the time when the derivation of the electrolyzed water from the water storage tank is completed, a predetermined amount of electrolyzed water set is supplied to the water tank, and then the electrolysis operation of the electrolyzed water generating mechanism is stopped. Thereby, according to the said electrolyzed water generating apparatus, it can prevent that electrolyzed water is supplied excessively to a water storage tank.

  The present invention relates to an electrolyzed water generating apparatus with a water storage tank. FIG. 1 shows an electrolyzed water generating apparatus according to an embodiment of the present invention. The electrolyzed water generating device includes an electrolyzed water generating mechanism 10, a water storage tank 20, and a control device 30.

  The electrolyzed water generating mechanism 10 is known per se, mainly composed of a diaphragm electrolyzer 11, and supplies electrolyzed water to the electrolyzer 11 and the electrolysis chambers R 1 and R 2 of the electrolyzer 11. A supply pipe 12 and a pair of outflow pipes 13 and 14 through which the electrolyzed water produced in each of the electrolysis chambers R1 and R2 flows out independently are configured. The supply pipe 12 is connected to the upstream side of the electrolysis chambers R1 and R2 at the downstream branch pipe sections 12a and 12b, and the outflow pipes 13 and 14 are connected to the electrolysis chambers R1 and R2. It is connected to the downstream side. In the electrolyzed water generation mechanism 10, in the electrolysis operation, electrolyzed water is supplied to the electrolysis chambers R 1 and R 2 through the supply pipe 12 and the electrodes disposed in the electrolysis chambers R 1 and R 2. A predetermined voltage is applied to 11a and 11b from the DC power supply 15. Thereby, the electrolysis operation by the electrolyzed water generating mechanism 10 is started. The electrolysis operation is stopped when the application of voltage from the DC power supply 15 is stopped and at the same time, the supply of water to be electrolyzed to the electrolysis chambers R1 and R2 is stopped. The start and stop of the electrolysis operation of the electrolyzed water generation mechanism 10 are controlled by the control device 30 described later.

  When the electrolysis operation by the electrolyzed water generation mechanism 10 is started, electrolysis generated acidic water is generated in one of the electrolysis chambers R1 and R2, and electrolysis generated alkaline water is generated in the other of the electrolysis chambers R1 and R2. The Of each electrolyzed water, the electrolyzed water intended to be used is supplied to the water storage tank 20 through one outflow pipe 13, and the electrolyzed water not intended to be used is spilled from the other. It is discharged through the pipe line 14 or discharged to another water storage tank. In addition, when the use of the electrolyzed water is also intended, the water is supplied to a water tank (not shown) configured in the same manner as the water tank 20. The supply control of the electrolyzed water to the water storage tank is performed in the same manner as the supply control of the electrolyzed water to the water storage tank 20.

  The water storage tank 20 is a per se known one that receives and stores electrolyzed water intended for use, and stores a predetermined amount of electrolyzed water supplied through the outflow pipe 13. A person who intends to use the electrolytically generated water stored in the water storage tank 20, when desired, leads the electrolytically generated water stored in the tank main body 21 of the water storage tank 20 to the tank main body 21. Derived through and collected. The electrolyzed water is collected by operating a derivation switch (not shown). An upper float switch 22 that is an upper limit water level sensor and a lower float switch 23 that is a lower limit water level sensor are disposed in a tank body 21 constituting the water storage tank 20. A flow rate detection sensor 16 for detecting the flow rate of the electrolyzed water flowing in the outflow pipe 13 is disposed in the middle of the outflow pipe 13 for supplying the electrolyzed water into the tank body 21 of the water storage tank 20. Has been.

  The upper float switch 22 detects the upper limit water level L1 of the electrolyzed water stored in the tank body 21 of the water storage tank 20, and outputs this to the control device 30 as a water level detection signal. The lower float switch 23 The lower limit water level L2 of the electrolyzed water stored in the tank body 21 of the tank 20 is detected and output to the control device 30 as a water level detection signal. The upper float switch 22 is turned on when the electrolyzed water level stored in the tank body 21 rises to the upper limit water level L1 when the electrolyzed water is supplied to the tank body 21, and the upper float switch 22 is turned on. When the electrolyzed water stored is led out from the tank body 21 and its water level falls below the upper limit water level L1, it is turned OFF. The lower float switch 23 is turned off when the electrolyzed water contained in the tank main body 21 is led out from the tank main body 21 and the water level drops to the lower limit water level L2, and the electrolysis stored in the tank main body 21 is turned off. It turns ON when the water level of the generated water rises above the lower limit water level L2 due to the supply of electrolytically generated water. In the electrolyzed water generating apparatus, a large tank is adopted as the water storage tank 20, and the capacity of electrolyzed water between the upper limit water level L1 and the lower limit water level L2 in the tank body 21 is set to 50L. .

  The control device 30 controls the electrolysis operation of the electrolyzed water generating device and includes a control program for electrolysis operation. In the electrolysis operation of the electrolyzed water generating device, the control device 30 starts to supply electrolyzed water to the electrolyzing chambers R1 and R2 of the diaphragm electrolyzer 11, and at the same time, the electrodes 11a of the electrolyzing chambers R1 and R2. , 11b, a predetermined voltage is applied. Thereby, the electrolysis operation of the electrolyzed water generating apparatus is started. In addition, when stopping the electrolysis operation of the electrolyzed water generating device, the control device 30 stops the supply of electrolyzed water to the electrolysis chambers R1 and R2 of the diaphragm electrolyzer 11, and at the same time, the electrolysis chambers R1 and R2. The application of voltage to each of the electrodes 11a and 11b is stopped. Thereby, the electrolysis operation of the electrolyzed water generating apparatus is stopped.

  The control device 30 controls the start and stop of the electrolysis operation of the electrolyzed water generating device based on the water level detection signals of the float switches 22 and 23.

  In addition, the control device 30 has a supply flow rate measurement function that counts the supply flow rate of electrolyzed water supplied to the tank body 21 of the water storage tank 20 based on the flow rate detection signal output from the flow rate detection sensor 16. When the supply amount of the electrolyzed water into the tank body 21 reaches a predetermined amount, the electrolyzed water generating device functions to stop the electrolysis operation. The control device 30 executes a control program for controlling the electrolysis operation of the electrolyzed water generating device based on the flowchart shown in FIG.

  The control device 30 starts execution of the control program by turning on the power to the electrolyzed water generating device. In step 101, the control device 30 determines the ON / OFF state of the lower float switch 23, and the lower float switch 23 is OFF. If so, the control program proceeds to step 102. In step 102, the control device 30 starts electrolysis operation of the electrolyzed water generating device and starts generating electrolyzed water, and at the same time, once cancels (resets) the measured value of the supply flow rate of electrolyzed water, The measurement (counting) of the supply flow rate is started. Thereby, the electrolyzed water generated by the electrolyzed water generator is supplied to the tank body 21 of the water storage tank 20 through the outflow pipe 13. Thereafter, the control device 30 advances the control program to step 103.

  In step 103, the control device 30 determines whether or not the electrolytically generated water stored in the tank body 21 of the water storage tank 20 is derived based on whether or not the derivation switch is operated, and the electrolytically generated water is in the derived state. If it is determined that the control program exists, the control program proceeds to step 104. In Step 104, the control device 30 confirms that the derivation of the electrolytically generated water from the tank and the main body 21 is completed, and returns the control program to Step 102. Thereby, the control apparatus 30 once cancels the measured value of the supply flow rate of the electrolyzed water measured so far, then restarts the measurement of the supply flow rate, and continues the electrolysis operation of the electrolyzed water generator.

  If the controller 30 determines in step 103 that the electrolytically generated water in the tank body 21 of the water storage tank 20 is in a non-derived state, the control device 30 advances the control program to step 105. In step 105, the control device 30 determines the operating state of the upper float switch 22. If the upper float switch 22 is in the OFF state, the control device 30 advances the control program to step 106. The supply flow rate to the main body 21 is confirmed. When it is determined that the supply amount of the electrolyzed water to the tank main body 21 has not reached a predetermined amount (for example, 30 L), the control device 30 returns the control program to step 103, and the electrolyzed water tank If it is determined that the supply amount to the main body 21 has reached a predetermined amount (for example, 30 L), the control program is advanced to step 107.

  If the control device 30 determines in step 105 that the upper float switch 22 is in the ON state, the control device advances the control program to step 107. In Step 107, the control device 30 stops the electrolysis operation of the electrolyzed water generating device, stops the electrolyzed water generation, and stops the electrolyzed water supply to the tank body 21 of the electrolyzed water. Thereafter, control device 30 advances the control program to step 108, and determines the operating state of upper float switch 22 at step 108. When it is determined that the upper float switch 22 is in the OFF state, the control device 30 returns the control program to Step 103, and when it is determined that the upper float switch 22 is in the ON state, the control device 30 Return to step 101.

  As described above, in the electrolyzed water generating apparatus, when the electrolyzed water stored in the tank body 21 of the water storage tank 20 is derived and consumed by a predetermined amount, Based on the water level detection signal of the float switch 23, the control device 30 starts electrolysis operation of the electrolyzed water generation mechanism 10 and supplies the electrolyzed water generated by the electrolyzed water generation mechanism 10 to the tank body 21 of the water storage tank 20. Then, the consumed electrolytically generated water is supplemented. The control device 30 performs the electrolysis operation of the electrolyzed water generation mechanism 10 in this case when the electrolyzed water supplied to the tank body 21 of the water storage tank 20 reaches a predetermined amount (30 L in the present embodiment). The supply of electrolytically generated water to the tank body 21 is stopped. For this reason, in the electrolyzed water generating apparatus, even when an abnormal state occurs in the upper float switch 22 and the float switch 22 becomes inoperable, the electrolyzed water is not supplied to the tank body 21 of the storage tank 20. It is not continued, and the electrolytically generated water in the tank body 21 does not fall into an excessive state. As a result, a large amount of electrolyzed water overflows from the tank body 21 and does not flow out in large quantities.

  Further, in the electrolyzed water generating apparatus, the electrolyzed water contained in the tank body 21 is also supplied when the electrolyzed water is supplied to the tank body 21 of the water storage tank 20 by the electrolysis operation of the electrolyzed water generating mechanism 10. It is easy to use so that can be derived and used. In this case, when the derivation of the electrolyzed water from the tank body 21 is completed, the control device 30 measures the supply flow rate of the electrolyzed water based on the flow rate detection signal from the flow rate detection sensor 16 without stopping the electrolysis operation. It functions to cancel (reset) the value once and restart (count) the measurement of the supply flow rate of the electrolyzed water based on the flow rate detection signal from the flow rate detection sensor. Thereby, from the time when the derivation of the electrolyzed water from the tank body 21 of the water storage tank 20 is completed, a predetermined amount of electrolyzed water set is supplied to the tank body 21, and then the electrolysis operation of the electrolyzed water generation mechanism 10 is performed. Is stopped, and the electrolytically generated water is prevented from being supplied to the tank body 21 in an excessive amount.
