Description

The present invention relates to an electrolyzed water generating apparatus.

  As one type of electrolyzed water generating device, a device main body in which a diaphragm electrolyzer is housed in a case, a first storage tank for storing electrolyzed acidic water generated in the diaphragm electrolyzer, and a diaphragm A second storage tank for storing the electrolytically generated alkaline water generated in the electrolytic tank, and discharging the electrolytically generated acidic water stored in the first storage tank through a dedicated extraction pipe; There is an electrolyzed water generating device of a type that discharges electrolytically generated alkaline water stored in a second storage tank through a dedicated pouring pipe (see Patent Document 1 and Patent Document 2).

  By the way, in the electrolyzed water generating device of this type, the electrolyzed acidic water stored in the first storage tank and the electrogenerated alkaline water stored in the second storage tank are consumed simultaneously or selectively with each other. When a predetermined amount is consumed, electrolytically generated acidic water generated in the anode electrolysis chamber of the diaphragm membrane electrolytic cell is introduced into the first storage tank by the electrolysis operation, and the diaphragm membrane electrolytic cell Means for introducing electrolytically generated alkaline water generated in the cathode side electrolysis chamber into the second storage tank to replenish each storage tank to a full state is adopted.

  However, in the electrolyzed water generating apparatus, the consumption amounts of the electrolyzed acidic water and the electrolyzed alkaline water are rarely consumed in a well-balanced manner, and the consumption amounts are often different. In this case, the replenishment amount of each electrolytically generated water in each storage tank is also different. For this reason, if the storage tank with the larger amount of electrolyzed water consumption is filled with water, the other electrolyzed water generated synchronously in the diaphragm electrolyzer is stored in the storage tank with the lower consumption amount. Since the introduced electrolyzed water is surplus by the difference in consumption, it must be drained.

  When the surplus electrolyzed water is electrolyzed alkaline water, there is not much problem with the drainage of the electrolyzed alkaline water, but when the surplus electrolyzed water is electrolyzed acidic water, the surplus electrolyzed water is generated. Water must be neutralized and drained. Normally, when draining electrolyzed acidic water, the electrolyzed acidic water is flowed into a neutralization tank containing a neutralizing agent such as cryolite and neutralized with a neutralizing agent contained in the neutralizing tank. A means for treating and draining as a neutral processing liquid that does not generate chlorine gas or the like is employed.

  By the way, since the neutralizing agent in the neutralization tank with which the electrolyzed water generating device of the type is equipped is gradually consumed according to the neutralization amount of the electrolyzed acidic water, the amount of consumption in which the neutralizing agent is set. At that time, it is necessary to replenish the neutralizing agent with the neutralizing tank. In the conventional electrolyzed water generating apparatus of this type, the neutralization tank is outside the case constituting the apparatus main body and is provided separately from each storage tank and the apparatus main body. For this reason, the administrator of the electrolyzed water generating apparatus can easily see the neutralizing agent in the neutralized tank in a separately placed state, and can confirm the timing of replenishment of the neutralizing agent.

  However, in the electrolyzed water generating device of this type, there is a request for storing the neutralization tank in the case constituting the main body of the apparatus and the neutralization tank in the case because of the appearance and securing the dedicated installation location. If it arrange | positions and accommodates, it will become difficult to visually recognize the inside of the neutralization tank accommodated in the case from the other components which comprise an apparatus main body, and the arrangement | positioning relationship of each water-system pipe line. In particular, since the case constituting the apparatus main body is normally closed with an opening / closing door, in order to visually recognize the inside of the neutralization tank, at least the opening / closing door must be opened, and the arrangement position of the neutralization tank For this reason, even if the open / close door is opened, the inside of the neutralization tank may not be visible as it is. The present invention is directed to addressing such problems.

  The present invention relates to an electrolyzed water generating apparatus. An electrolyzed water generating apparatus to which the present invention is applied stores an apparatus main body in which a diaphragm electrolytic cell and a neutralizing tank are housed in a case, and electrolyzed acidic water generated in the diaphragm electrolyzed tank. A first storage tank; and a second storage tank for storing the electrolytically generated alkaline water generated in the diaphragm membrane electrolytic cell, wherein the electrolytically generated acidic water stored in the first storage tank is dedicated The electrolytically generated alkaline water stored in the second storage tank is poured out through a dedicated outlet line, and the excess electrolytically generated acidic water is neutralized. It is an electrolyzed water generating device of a type that flows into the tank and neutralizes with a neutralizing agent accommodated in the neutralizing tank and then discharges it through a discharge pipe.

  Thus, the electrolyzed water generating device according to the present invention has a function of calculating the consumption of the neutralizing agent accommodated in the neutralization tank from the amount of electrolyzed acidic water flowing into the neutralization tank. And a control device having a function of driving a recognition means for recognizing that the neutralizer has reached a set consumption, and the control device is a consumption for which a calculated neutralizer consumption is set. The recognition means is driven when the value reaches.

  Moreover, the electrolyzed water generating apparatus according to the present invention introduces electrolyzed acidic water into the first storage tank in the electrolysis operation of the diaphragm electrolyzer, and electrolyzed alkaline in the second storage tank. After the water is introduced and the electrolytically generated acidic water introduced into the first storage tank reaches the set amount, surplus electrolytically generated acidic water exceeding the set amount flows into the neutralization tank. The neutralizing agent contained in the neutralization tank is neutralized and discharged through the discharge pipe, and the control device is a consumption amount in which the neutralizing agent in the neutralization tank is set. The cognitive means is driven when reaching the value, and the electrolysis operation of the diaphragm electrolyzer is stopped when the neutralizing agent reaches the set consumption limit.

  In the electrolyzed water generating apparatus according to the present invention, the control device is configured to change the first storage from the duration of electrolysis operation and the generated flow rate of electrolyzed water from the time when the first storage tank becomes full. It can comprise so that the quantity of the excess electrolysis production | generation acidic water which overflows from the inside of a tank and flows in into the said neutralization tank may be calculated.

  In the electrolyzed water generating apparatus according to the present invention, the amount of consumption of the neutralizing agent in the neutralizing tank is controlled by the control apparatus even though the neutralizing tank is installed and stored in the case constituting the apparatus main body. The administrator of the electrolyzed water generating device is made to recognize through the recognition means that the set consumption has been reached. For this reason, the manager should accurately recognize the replenishment timing of the neutralizing agent by the recognizing means, replenish the neutralizing agent, and avoid the electrolytic operation in the absence of the neutralizing agent in the neutralization tank. Can do.

  Further, in the electrolyzed water generating apparatus according to the present invention, when a control device having a function of stopping the electrolysis operation of the diaphragm membrane electrolytic cell when the neutralizer reaches the set consumption limit is adopted. If the administrator cannot confirm the recognition by the cognitive means or confirms the recognition by the cognitive means, the controller is Stop electrolysis as a means of time. For this reason, the electrolysis driving | running in the state in which the neutralizing agent in a neutralization tank does not exist can be avoided.

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 via the switching valve 41a, and the outflow pipes 33a and 33b are connected to the introduction pipes 33c and 33d via 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. . A pressure reducing valve 43 a and a water softener 21 are interposed in a water supply pipe 34 connected to a water supply source such as a water pipe, and a branch pipe section of the water supply pipe 34 is connected to the salt water tank 22. . An open / close valve 43b is interposed in the branch pipe section. 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. Is opened so that water to be electrolyzed can be simultaneously supplied to the electrolyzers 23 and 24. When either one of the electrolyzers 23 and 24 is used for electrolysis, only one of the electrolyzers is electrolyzed with one of the on-off valves 43c and 43d opened. Be able to supply water.

  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. The water is drained through the drainage pipe 36c as it is without reacting with the summing agent.

  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 extraction pipe 37b and provided to the consumer.

  The first extraction pipe line 37a is connected to the lower front side portion of the first storage tank B, extends along the lower front side portion of the case main body 11, and penetrates the lower front side portion of the case main body 11. The case body 11 extends rearward along the bottom of the case body 11, and is connected to a discharge port 11 a provided on the right side of the case body 11 and extending upward in the case body 11 at the rear. A second extraction pipe (not shown) is connected to the discharge port portion 11a when the electrolyzed water generating device is installed. The second extraction pipe line extends to a place where the consumer uses, and the electrolytically generated acidic water is poured out at the place.

  On the other hand, the second pouring line 37b is connected to the lower front side portion of the second storage tank C and extends along the lower front side portion of the case main body 11 to connect the lower front side portion of the case main body 11 to the lower front side portion. It penetrates and extends rearward along the bottom of the case body 11, and in the rear, it extends upward in the case body 11 and is connected to a discharge port 11 b provided on the left side above the case body 11. When the electrolyzed water generating device is installed, a second extraction pipe (not shown) is connected to the discharge port portion 11b. The second extraction pipe line extends to a place where the consumer uses, and the electrolytically generated alkaline water is poured out at the 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.

  Accordingly, a discharge pump 42b and an open / close valve 43e are interposed in the first discharge pipe 37a, and a discharge pump 42c and an open / close valve 43f are interposed in the second discharge pipe 37b. It is disguised. In the electrolyzed water generating apparatus, when the pouring pump 42b is driven with the on-off valve 43e of the first pouring pipe 37a open, the electrolyzed acidic water stored in the first storage tank B is the first. It is poured out through one dispensing line 37a and provided to consumers. In addition, if the pumping pump 42c is driven in a state in which the on-off valve 43f of the second pouring line 37b is opened, the electrolytically generated alkaline water stored in the second storage tank C is stored in the second pouring line 37b. And is dispensed to consumers.

  In the electrolyzed water generating apparatus, each of the pumping pumps 42c and 42d is interposed in a part of the case main body 11 in the first discharging pipes 37a and 37b. The outlet pipes 37a and 37b are interposed in the middle part of the part extending along the front side part below the case main body 11. Each of the on-off valves 43e and 43f is a lever-turning on-off valve that opens and closes by turning the lever, and is interposed so that the lever is positioned at the top of the pipe line portion.

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

  The under cover 13 covers the pipe line part exposed to the front side part below the case body 11 in each of the extraction pipe lines 37a and 37b, and the on-off valves 43e and 43f interposed in the pipe line part. And functions to protect and to improve the appearance of the electrolyzed water generating device. The under cover 13 is easily removable, and the on / off valves 43e and 43f can be opened and closed with the under cover 13 removed. When the on / off valves 43e and 43f are closed, the lever is substantially orthogonal to the pipe line. Therefore, the under cover 13 cannot be attached to the case main body 11. In order to attach the under cover 13 to the case main body 11, it is necessary to turn the lever to open the on-off valves 43e and 43f that are parallel to the pipe line portion.

  The electrolyzed water generating device is equipped with a control device 50. The control device 50 performs electrolysis operation of the electrolyzed water generating device, introduction of electrolyzed water into the storage tanks B and C, and from the storage tanks B and C. The discharge of each electrolytically generated water and the neutralization treatment in the neutralization tank 25 are controlled. FIG. 4 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. It changes to an anode side electrolysis chamber, and switching valve 41a, 41b is switched in synchronization 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 pours the electrolytically generated acidic water in the first storage tank B through the extraction pipe 37a, and the consumer generates the electrolytically generated alkaline water. Is selected, the electrolytically generated alkaline water in the second storage tank C is poured out through the dispensing 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 of electrolytically generated acidic water flowing in from B, and it is necessary to replenish the neutralizing tank 25 with the neutralizing agent when a predetermined amount of the neutralizing agent is consumed. 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 present invention addresses such a problem. In the present invention, the control device 50 provided in the electrolyzed water generating device is used to control the amount of electrolyzed acidic water that has flowed into the neutralizing tank 25 with the amount of neutralizer consumed. And a function of driving a recognition means for recognizing that a set amount of the neutralizing agent has been consumed. Furthermore, in the present invention, 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 configured to have a function of stopping the electrolysis operation of the diaphragm electrolyzers 23 and 24 when the set consumption limit is reached.

  In the present embodiment, the control device 50 determines the duration of the electrolysis operation from the time of full water and the electrolytically generated water based on the detection signal from the float switch B2 that has detected that the first storage tank B is full. The amount of surplus electrolytically generated acidic water that has flowed into the neutralization tank 25 is calculated from the set flow rate per time, and the consumption of the neutralizing agent in the neutralization tank 25 is calculated from the surplus electrolytically generated acidic water amount. calculate. When the consumption of the neutralizing agent calculated every moment (for example, 300 g of cryogenic stone is reduced per 1000 liters of electrolytically generated acidic water) reaches the set amount of consumption (for example, 14,000 L of electrolytically generated acidic water passes through and consumes 4,2 kg of cryogenic stone). The control device 50 blinks a recognition means installed on the operation panel, for example, a warning lamp E, and makes the administrator of the electrolyzed water generating device recognize the timing when the neutralizing agent should be replenished.

  For this reason, the manager recognizes the replenishment timing of the neutralizing agent by blinking of the warning lamp E, replenishes the neutralizing tank 25 with a predetermined amount of the neutralizing agent, and presses the reset button to store the current value. The consumption of the neutralizing agent is zero. 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. .

  In addition, the manager may not notice the blinking of the warning lamp E or may forget to replenish the neutralizing agent even though the manager has recognized the blinking of the warning lamp E. In this case, the controller 50 may It works like The control device 50 reaches a predetermined consumption amount (for example, passing through 20000L of electrolytically generated acidic water and consuming 6 kg of cryolite), and the neutralizing agent has reached the consumption limit. In some cases, the electrolysis operation of the diaphragm electrolyzers 23 and 24 is urgently stopped, and the blinking speed of the warning lamp E is increased so that the manager can easily recognize the fact. 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.
