Accordingly, a first object of the present invention is to address these problems.

  Further, in the electrolyzed water generating apparatus of this type, since a salt dilute aqueous solution such as salt is generally used as the electrolyzed water, a salt water tank that contains concentrated salt water for preparing the electrolyzed water is stored in the case. Has been. Moreover, in the electrolyzed water generating device of this type, the excess electrolyzed acidic water is neutralized in the neutralization tank and drained as a neutral treatment liquid, but the neutralization tank is stored in the case. It is advantageous to do so. In these cases, the salt in the salt water tank and the neutralizing agent in the neutralization tank are gradually consumed, so when a predetermined amount of salt or neutralizing agent has been consumed, It is necessary to replenish the tank.

As shown in FIG. 3, a water softener 21, a salt water tank 22, a pair of electrolytic baths 23 and 24, and a neutralization bath 25 are disposed and housed therein. Connected appropriately by road.

  The electrolyzers 23 and 24 which are main components of the apparatus main body A are diaphragm electrolyzers, and the electrolyzer body includes a pair of electrolysis chambers partitioned by a diaphragm. Each electrolysis chamber is controlled so that the polarity is reversed when the electrolysis operation has passed for a predetermined time, and the anode electrolysis chamber is switched to the cathode electrolysis chamber and the cathode electrolysis chamber is changed to the anode electrolysis chamber. It is configured to be switched.

  Supply lines 31a and 31b for water to be electrolyzed are connected upstream of the electrolysis chambers constituting the electrolyzers 23 and 24, and are generated in the electrolysis chambers downstream of the electrolysis chambers. Outflow pipes 32a, 32b, 33a, 33b through which the electrolytically generated water flows out are connected to each other. The outflow pipes 32a and 32b are connected to the introduction pipes 32c and 32d through the switching valve 41a, and the outflow pipes 33a and 33b are connected to the introduction pipes 33c and 33d through the switching valve 41b, respectively. ing.

  The introduction pipe line 32c connected to the electrolytic cell 23 side is connected to the upper side of the first storage tank B, and the introduction pipe line 32c is connected to the electrolytic cell 24 side. 33c is connected. The introduction pipe line 32d connected to the electrolytic cell 23 side is connected to the introduction pipe line 33d connected to the second electrolysis water tank 24 side, and the introduction pipe line 33d is the second storage tank C. It is connected to the upper part of the side.

  The introduction pipe line 32c on the electrolytic cell 23 side is a dedicated introduction line for the electrolytically produced acidic water, and the electrolytically produced acidic water produced in the anode side electrolytic chambers of the electrolytic cells 23 and 24 is the first one. It functions to be introduced into the storage tank B. The introduction conduit 33d on the electrolyzer 24 side is a dedicated introduce conduit for the electrolyzed alkaline water, and the electrolyzed alkaline water produced in the cathode electrolysis chambers of the electrolyzers 23 and 24 is the first It functions to be introduced into the second storage tank C.

  In each electrolyzer 23, 24, when the electrolysis operation is continued for a predetermined time after the electrolysis operation is set, the polarity of each electrolysis chamber is controlled to be reversed in the positive and negative directions. Then, the switching valves 41a and 41b are switched to change the connection relationship between the outflow pipes 32a and 32b on the electrolytic cell 23 side and the introduction pipes 32c and 32d, and on the electrolytic cell 24 side. The connection relationship between the outflow pipes 33a and 33b and the introduction pipes 33c and 33d is changed.

  As a result, the electrolyzed acidic water generated in the anode electrolysis chambers of the electrolyzers 23 and 24 is always introduced into the first storage tank B through the introduction pipe line 32c. The electrolytically generated alkaline water generated in the cathode side electrolysis chambers of the tanks 23 and 24 is always introduced into the second storage tank C through the introduction pipe line 33d.

  The electrolyzed water supplied to the electrolyzers 23 and 24 is prepared by supplying a set amount of salt water from the salt water tank 22 to the raw water softened through the water softener 21 by the pulse pump 42a. .

The salt water tank 22 is connected to the water supply line 34 through a salt water supply line 35, and a pulse pump 42 a is interposed in the salt water supply line 34.

  In the water circuit, raw water that has been softened flows through the water supply pipe 34 at a predetermined flow rate, and a predetermined high-concentration salt water prepared in the salt water tank 22 is added to the flowing raw water by the pulse pump 42a. Is continuously supplied for a predetermined amount. Thereby, electrolyzed water (diluted salt water having a predetermined concentration set) is prepared in the water supply pipe 34, and the prepared electrolyzed water passes through the supply pipes 31a and 31b of the electrolyzed water and is electrolyzed. It is supplied to the tanks 23 and 24. The electrolyzed water supplied to the electrolyzers 23 and 24 undergoes diaphragm membrane electrolysis in the electrolyzers of the electrolyzers 23 and 24 while flowing through the electrolyzers 23 and 24.

  In the electrolyzed water generating apparatus, the electrolyzers 23 and 24 can be simultaneously electrolyzed, and any one of the electrolyzers 23 and 24 can be selected and electrolyzed. For this reason, on-off valves 43c and 43d are respectively provided in the supply pipes 31a and 31b of the electrolyzed water, and when the electrolyzers 23 and 24 are simultaneously subjected to electrolysis, the on-off valves 43c and 43d are provided.

  The neutralization tank 25 of the electrolyzed water generating device contains a neutralizing agent such as cryolite, and neutralizes the excess electrolyzed acidic water so that no chlorine gas is generated. It functions to drain as a liquid. The neutralizing tank 25 is connected to the outflow pipes 36a and 36b connected to the overflow pipes B1 and C1 of the respective storage tanks B and C. Thereby, the electrolytically generated acidic water that overflows through the overflow pipe B1 in the first storage tank B flows into the neutralization tank 25 through the outflow pipe 36a, and the neutralizing agent in the neutralization tank 25 Is neutralized and discharged as a neutral processing liquid through the drain pipe 36c.

  In addition, the electrolytically generated alkaline water that overflows through the overflow pipe C1 in the second storage tank C flows into the neutralization tank 25 through the outflow pipe 36b. In this state, the water is drained through the drain pipe 36c.

  In the electrolyzed water generating apparatus, the electrolyzed acidic water stored in the first storage tank B is poured out through the first pouring line 37a and provided to consumers. Further, the electrolytically generated alkaline water stored in the second storage tank C is poured out through the second dispensing pipe 37b and provided to the consumer.

  The first extraction pipe 37 a is connected to the lower front side of the first storage tank B, extends horizontally along the lower front side of the case body 11, and the lower front side of the case body 11. And extends rearwardly along the bottom of the case body 11, and is connected to a discharge port 11 a that extends upward in the case body 11 and is provided on the right side above the case body 11. . When the electrolyzed water generating apparatus is installed, another discharge pipe (not shown) is connected to the discharge port portion 11a. The said extraction pipe line is extended to the place where a consumer uses, and the electrolysis production | generation acidic water is poured out in the said place.

  On the other hand, the second pouring line 37b is connected to the lower front side of the second storage tank C, extends horizontally along the lower front side of the case main body 11, and extends below the case main body 11. It penetrates the front side part, extends rearward along the bottom part of the case main body 11, and extends rearward in the case main body 11 and is connected to a discharge port 11 b provided on the left side above the case main body 11. Yes. When the electrolyzed water generating device is installed, another discharge pipe (not shown) is connected to the discharge port portion 11b. The said extraction pipe line is extended to the place where a consumer uses, and discharges electrolyzed alkaline water in the said place.

  A vent hole portion 11 c is provided on the upper right side of the case body 11. An exhaust pipe (not shown) connected to the electrolytically generated acidic water introduction pipe 32c is connected to the vent 11c, and functions to exhaust the gas generated in the introduction pipe 32c. Further, vent portions 11 d and 11 e are provided on the left side above the case body 11. An exhaust pipe (not shown) connected to the electrolytically generated alkaline water introduction pipe 33d is connected to the vent 11d, and functions to exhaust gas generated in the introduction pipe 33d. Further, an exhaust pipe (not shown) connected to the upper part of the neutralization tank 25 is connected to the vent part 11e, and functions to exhaust gas generated in the neutralization tank 25.

  Therefore, the first pumping line 37a is provided with a pumping pump 42b and an on-off valve 43e, and the second pumping line 37b is provided with a pumping pump 42c and an on-off valve 43f. Is intervening. In the electrolyzed water generating apparatus, when the pouring pump 42b is driven in a state where the opening / closing valve 43e of the first pouring pipe line 37a is opened, the electrolyzed acidic water stored in the first storage tank B is generated. It is poured out through the first dispensing line 37a and provided to consumers. Further, if the discharge pump 42c is driven in a state in which the on-off valve 43f of the second outlet pipe 37b is opened, the electrolytically generated alkaline water stored in the second storage tank C becomes the second outlet pipe line. It is dispensed through 37b and provided to consumers.

  In the electrolyzed water generating apparatus, each of the pumping pumps 42b and 42c is interposed in a portion in the case main body 11 in the first discharging pipes 37a and 37b, and each of the on-off valves 43e and 43f The extraction pipes 37a and 37b are interposed in the middle part (front pipe parts 37a1 and 37b1) of the part extending horizontally along the front side part below the case body 11. Each on-off valve 43e, 43f is a lever-turning on-off valve that opens and closes by a lever turning operation, and is interposed such that the levers 43e1, 43f1 are located at the top of the pipe line.

  For this reason, if the levers 43e1, 43f1 of the on-off valves 43e, 43f are horizontally rotated at the top of the pipe line, the on-off valves 43e, 43f can be opened and closed. In the electrolyzed water generating apparatus, the state where the levers 43e1 and 43f1 are in parallel positions along the pipe line is set to the state where the on-off valves 43e and 43f are open, and the levers 43e1 and 43f1 are rotated. The on-off valves 43e and 43f are closed in a crossed state substantially orthogonal to the pipe line portion. An under cover 13 is fitted and detachably attached to the lower front side portion of the case body 11.

  The under cover 13 is connected to the pipe parts (front pipe parts 37a1, 37b1) horizontally located on the front side part below the case main body 11 in the extraction pipes 37a, 37b and the front pipe parts 37a1, 37b1. It functions to cover and protect the installed on-off valves 43e and 43f and to improve the appearance of the electrolyzed water generating device. The under cover 13 can be easily attached and detached, and the open / close valves 43e and 43f can be opened and closed with the under cover 13 removed. When the open and close valves 43e and 43f are closed, the levers 43e1 and 43f1 are connected to the pipe section. The under cover 13 cannot be attached to the case body 11 because it protrudes forward in a substantially orthogonal shape. In order to attach the under cover 13 to the case main body 11, it is necessary to turn the levers 43e1 and 43f1 to open the on-off valves 43e and 43f that are parallel to the pipe line portion.

  The electrolyzed water generating apparatus includes a control device 50 shown in FIG. The control device 50 performs electrolysis operation of the electrolyzed water generating device, introduction of electrolyzed water into the storage tanks B and C, extraction of electrolyzed water from the storage tanks B and C, and neutralization. The neutralization process in the tank 25 is controlled. FIG. 8 schematically shows a control circuit of the control device 50.

  The control device 50 is a microcomputer and includes a CPU and a drive circuit. At the time of electrolysis operation, the control device 50 drives the pulse pump 42a to continuously supply the set amount of salt water to the softened raw water flowing in the water supply pipe 34 by a set amount. Prepare a diluted salt water (electrolyzed water) of the specified concentration. In addition, during the electrolytic operation, the control device 50 opens and closes the open / close valves 43c and 43d based on a driver's instruction for selecting the electrolytic mode, and performs simultaneous electrolytic operation of the electrolytic cells 23 and 24 and each electrolytic bath 23. , 24 is selected as an electrolysis mode for electrolysis operation.

  During the electrolysis operation, the control device 50 sets the anode side electrolysis chamber to the cathode side electrolysis chamber and the cathode side electrolysis chamber to the cathode side electrolysis chamber among the electrolysis chambers based on a command to reverse the polarity of each electrolysis chamber of the electrolyzers 23 and 24 Each is changed to the anode side electrolysis chamber, and the switching valves 41a and 41b are switched in synchronism with this. Thereby, the control apparatus 50 always introduces the electrolytically generated acidic water generated in the anode side electrolytic chambers of the electrolytic cells 23 and 24 into the first storage tank B through the introduction pipe line 32c. Electrolytically generated alkaline water generated in the cathode side electrolysis chambers 23 and 24 is always introduced into the second storage tank C through the introduction pipe line 33d.

  Float switches B2 and C2 are disposed in the storage tanks B and C, and cooperate with the overflow pipes B1 and C1 so that the electrolytically generated water in the storage tanks B and C is set to a predetermined amount. maintain. Electrolytically generated acidic water and electrolytically generated alkaline water are generated synchronously during the electrolysis operation, and are introduced into the respective storage tanks B and C in substantially the same amount. When the control device 50 detects that the electrolyzed water stored in the storage tanks B and C has the same amount and the float switches B2 and C2 have reached the full tank, the electrolytic cell 23 , 24 is stopped. Further, the control device 50 resumes the electrolysis operation based on the detection signal of the float switch that has detected the electrolytically generated water in at least one of the storage tanks B and C when a predetermined amount is consumed. Then, each electrolytically generated water is introduced into both the storage tanks B and C and replenished.

  The control device 50 drives the extraction pump on the side of the electrolytically generated water selected by the consumer based on the instruction for discharging the electrolytically generated water by the consumer to inject the selected electrolytically generated water through a dedicated extraction line. Let it come out. When the consumer selects electrolytically generated acidic water, the control device 50 discharges the electrolytically generated acidic water in the first storage tank B through the first extraction pipe line 37a, and the consumer performs electrolysis. When the generated alkaline water is selected, the electrolytically generated alkaline water in the second storage tank C is poured out through the second pouring line 37b. The extraction of electrolyzed water can be stopped automatically when a predetermined time has elapsed, and can also be stopped by a manual stop operation by the consumer.

  By the way, in the said electrolyzed water production | generation apparatus, the consumption of the electrolysis production | generation acidic water stored in the 1st storage tank B, and the consumption of the electrolysis alkaline water stored in the 2nd storage tank C In some cases, the electrolytically generated water of only one of the storage tanks B and C reaches a predetermined consumption. In this invention, the said storage tank is called the storage tank in an empty tank state for convenience. In this case, when the float switch detects that the tank is in an empty state, the control device 50 starts electrolysis operation based on the detection signal, and introduces each electrolyzed water into the storage tanks B and C. .

  For this reason, each electrolyzed water is introduced into each of the storage tanks B and C so that the storage tanks B and C are filled up, but the storage tank that was not in an empty tank state is in an empty tank state. The tank is full before the storage tank that was showing. As a result, from the storage tank that has been filled up first, surplus electrolytically generated water overflows from the overflow pipe and enters the neutralization tank 25 through the drainage pipe according to the electrolytically generated water introduced thereafter. Will flow in.

  For example, when the inside of the first storage tank B is filled quickly, the electrolytically generated acidic water in the first storage tank B flows into the neutralization tank 25 through the drain line 36a, and is neutralized. Neutralization is performed with a neutralizing agent such as cryolite stored in the tank 25, and the neutral processing liquid is drained through the drain line 36c. Further, when the second storage tank C is quickly filled up, the electrolytically generated alkaline water in the second storage tank C flows into the neutralization tank 25 through the drain line 36b, and is neutralized. In the tank 25, the water is drained through the drain pipe 36c without any treatment.

  Therefore, when the electrolytically generated acidic water flows from the first storage tank B and flows into the neutralization tank 25, the neutralizing agent accommodated in the neutralization tank 25 is the first storage tank. It will be consumed according to the amount (surplus amount) of electrolytically generated acidic water flowing from B, and when a predetermined amount of neutralizing agent is consumed, it is necessary to replenish the neutralizing tank 25 with the neutralizing agent. There is. However, in the electrolyzed water generating apparatus, since the neutralization tank 25 is disposed in the case body 11 closed by the open / close door 12, the amount of the neutralizing agent in the neutralization tank 25 is externally supplied. It is difficult to visually recognize, and it is possible to lose the replenishment timing of the neutralizing agent.

  The electrolyzed water generating apparatus includes means for dealing with such a problem. In the electrolyzed water generating device, the control device 50 to be equipped has a function of calculating the consumption of the neutralizing agent from the amount of electrolyzed acidic water that has flowed into the neutralizing tank 25, and a set amount of the neutralizing agent is consumed. It has the structure which has the function which drives the recognition means to recognize that. Further, the controller 50 provided in the electrolyzed water generating device drives a recognition means for recognizing that a set amount of the neutralizing agent in the neutralizing tank 25 has been consumed, and the neutralizing agent is set. When the consumption limit is reached, the electrolysis operation of the diaphragm electrolyzers 23 and 24 is stopped.

  In the electrolyzed water generating device, the control device 50 determines the duration of electrolysis operation from the point of water filling and the electrolysis generation based on the detection signal from the float switch B2 that detects that the first storage tank B is full. The surplus electrolytically generated acidic water amount that has flowed into the neutralization tank 25 is calculated from the water generation flow rate, and the consumption of the neutralizing agent in the neutralization tank 25 is calculated from the surplus electrolytically generated acidic water amount. When the consumption amount of the neutralizing agent calculated every moment reaches the set consumption amount, the control device 50 turns on the recognition means installed on the operation panel, for example, the warning lamp E, and the electrolyzed water generating device. The manager of the system recognizes when the neutralizing agent should be replenished.

  For this reason, the manager recognizes the replenishment timing of the neutralizing agent by lighting the warning lamp E, and replenishes the neutralizing tank 25 with a predetermined amount of the neutralizing agent. Thereby, the electrolysis driving | running in the state in which the neutralizing agent does not exist in the neutralization tank 25 can be avoided. In this embodiment, the warning lamp E is used as the recognition means. However, a known appropriate warning means can be adopted as the recognition means. For example, a warning buzzer or the like is extremely effective as the recognition means. .

  Further, the manager may not notice the lighting of the warning lamp E, or may forget to replenish the neutralizing agent even though the manager recognizes the lighting of the warning lamp E. It works like When the neutralizing agent reaches the consumption limit after the neutralizing agent in the neutralizing tank 25 reaches the predetermined consumption, the control device 50 performs the electrolysis operation of the diaphragm electrolyzers 23 and 24. Emergency stop. Thereby, it is possible to reliably avoid the electrolysis operation in a state where the neutralizing agent is not present in the neutralization tank 25.

  Thus, the under cover 13 employed in the electrolyzed water generating apparatus covers the front side pipe parts 37a1 and 37b1 that are horizontally positioned on the front side part below the case 10 in the respective extraction pipes 37a and 37b. When replenishing not only the function but also the salt water tank 22 with salt, the salt that protrudes from the salt inlet 22 a and falls into the case 10, and the neutralizer 25 is replenished with neutralizer.

When levers 43e1 and 43f1 adopt a state in which the parallel state along the pipe line portion is set to the open state and the intersection state substantially orthogonal to the pipe line portion is set to the closed state, The under cover 13 can be attached when the levers 43e1 and 43f1 are in an open state at a parallel position along the pipe line portion. However, when the levers 43e1 and 43f1 are in a closed state substantially orthogonal to the pipe line part, the under cover 13 can be attached. Can not be installed. For this reason, in the electrolyzed water generating apparatus, it is possible to reliably prevent forgetting to open the on-off valves 43e and 43f after the under cover 13 is removed and the on-off valves 43e and 43f are closed.

  In the electrolyzed water generating apparatus, when a predetermined amount of salt such as salt stored in the salt water tank 22 is consumed, a predetermined amount of neutralizing agent stored in the neutralization tank 25 is consumed. In such a case, it is necessary to replenish the salt water tank 22 with the salt and replenish the neutralizing tank 25 with the neutralizing agent.

  The salt water tank 22 is replenished with salt through the charging cylinder 15b with the open / close door 15c provided on the operation panel 15 open. If the inlet 22a of the salt water tank 22 is opened and salt is introduced through the inlet cylinder 15b, most of the salt introduced through the inlet cylinder 15b is introduced into the salt water tank 22 through the salt inlet 22a and replenished. A small amount of salt charged through the charging cylinder 15b protrudes from the salt charging port 22a and falls.

  However, the salt that protrudes from the salt inlet 22 a falls and is received along the flange 13 b of the undercover 13 and does not fall into the case body 11. For this reason, generation | occurrence | production of the rust in the case main body 11 itself resulting from the salt which fell in the case main body 11, the metal various components accommodated in the case main body 11, piping, etc. is prevented. Become.

  Further, replenishment of the neutralizing agent into the neutralizing tank 25 is performed by opening the neutralizing agent inlet 25b of the neutralizing tank 25 and passing through the opened neutralizing agent inlet 25b. As a result, most of the neutralizing agent to be charged is charged into the neutralization tank 25 through the neutralizing agent charging port 25b and replenished. However, a small amount of the neutralizing agent is charged to the neutralizing agent charging port 25b. It falls off and falls.

  However, the neutralizing agent that protrudes from the neutralizing agent inlet 25 b falls and is received along the flange 13 b of the undercover 13, and does not fall into the case body 11.
