Description

The present invention relates to an electrolyzed water generating apparatus.

  One type of electrolyzed water generating device is a diaphragm electrolysis type electrolyzed water generating device. The electrolyzed water generating device of this type is generally a case in which a diaphragm electrolyzer is housed in a case, and the electrolyzed acidic water generated in the diaphragm electrolyzer is poured out through a dedicated pouring line. In addition, the electrolytically generated alkaline water generated in the diaphragm membrane electrolytic cell is poured out through a dedicated dispensing conduit (see Patent Document 1 and Patent Document 2).

  By the way, in the electrolyzed water generating device of this type, the electrolyzed acidic water and the electrolyzed alkaline water are generated in the same amount in the diaphragm membrane electrolytic cell synchronously. When a difference arises, it is necessary to drain the surplus electrolytically generated water. Among these electrolyzed water, when electrolyzed alkaline water is drained, there is no problem even if it is drained without any treatment, but when electrolyzed acidic water is drained, prior to draining. Need to be neutralized. For this reason, it is common to introduce surplus electrolytically generated acidic water into a neutralization tank containing a neutralizing agent such as cryolite, neutralize it, and drain it as a neutral treatment liquid. The neutralization tank is usually a separate type placed outside the case containing the diaphragm electrolytic cell.

  By the way, in the electrolyzed water generating device of this type, in order to eliminate the securing of a dedicated installation location for installing a separately-installed neutralizing tank, and to improve the appearance of the electrolyzed water generating device, It is required to be housed together with the diaphragm membrane electrolytic cell in a case housing the diaphragm membrane electrolytic cell. However, when the neutralization tank is accommodated in the case, there is a possibility that a problem may occur in the operation of replenishing the neutralization agent into the neutralization tank.

  The neutralizer in the neutralization tank is gradually consumed according to the amount of neutralization treatment of the electrolyzed acid water, and when the neutralizer consumption reaches the predetermined consumption, the neutralizer is neutralized. It is necessary to refill inside. The neutralization tank is usually replenished through a neutralizer charging port provided on the upper side surface of the cylindrical tank which is the tank body. In the separate type neutralization tank, since the surroundings are a large space, the operation of replenishing the neutralization agent into the neutralization tank can be easily performed without any problem.

  However, if the neutralization tank is stored in the case, open the door that closes the front opening of the case body, and remove the cap that closes the charging port provided in the neutralization tank, The neutralizing agent is charged into the neutralization tank through the opened charging port. In this case, a salt water tank, a water softener, etc. are installed in the case where the neutralization tank is installed, and water pipes connected to each other around these components are installed. Therefore, there is only a very limited space around the neutralization tank. For this reason, the operation of replenishing the neutralizing agent into the neutralizing tank becomes extremely difficult, and the amount of the neutralizing agent that protrudes from the charging port and falls into the case when the neutralizing agent is charged increases. Accordingly, an object of the present invention is to address these problems, and at the same time, to improve the neutralization efficiency with the neutralizing agent, and further to increase the consumption efficiency of the neutralizing agent.

  The present invention relates to an electrolyzed water generating apparatus. An electrolyzed water generating apparatus to which the present invention is applied includes an apparatus main body in which a diaphragm electrolytic cell and a neutralizing tank are housed in a case, and among electrolyzed acidic water generated in the diaphragm electrolyzed tank This is an electrolyzed water generating device that flows the excess electrolytically generated acidic water into the neutralizing tank, neutralizes it with a neutralizing agent contained in the neutralizing tank, and discharges it through a drain pipe.

  Thus, in the electrolyzed water generating apparatus according to the present invention, the neutralization tank is mainly composed of a cylindrical tank formed on an inclined surface whose upper side surface is inclined downward, and on the upper inclined surface of the tank. Is provided with a neutralizing agent charging port for charging the neutralizing agent, and has an outlet portion connected to the drainage pipe at an upper portion on one side surface of the tank, and an upper and lower middle portion on the other side surface of the tank.

A pipe is provided, and an intermediate portion of the introduction pipe is connected to the introduction port.

  In the electrolyzed water generating apparatus according to the present invention, the bottom portion of the tank constituting the neutralization tank is formed in a V-shaped bottom portion having a V-shaped cross section in a state of being installed in the case, The lower end portion of the introduction pipe may be configured to extend near the bottom portion of the V-shaped bottom portion of the tank. Further, in the electrolyzed water generating apparatus according to the present invention, a drain line for draining excess electrolyzed alkaline water is connected to the introduction pipe, and electrolyzed acidic water and electrolyzed alkaline water are selected in the tank. Can be configured to be introduced automatically.

  In the electrolyzed water generating apparatus according to the present invention, surplus electrolytically generated acidic water is neutralized with a neutralizing agent accommodated in the tank of the neutralizing tank, and is neutrally discharged as a processing liquid. Accordingly, the neutralizing agent in the tank of the neutralization tank is gradually consumed according to the neutralization amount of the electrolytically generated acid water, and when the consumption of the neutralizing agent reaches a predetermined amount, the neutralizing agent is stored in the tank. It is necessary to refill inside. Replenishment of the neutralizing agent into the tank is performed by opening the door that closes the front opening of the case body.

  When the open / close door is opened, the neutralization tank accommodated in the case appears in front of the operator. In the neutralization tank that appears, the upper inclined surface of the tank that is the main body of the neutralization tank is inclined downward, so that the inlet formed in the upper inclined surface is located at a position that is easy for the operator to see. In addition, since there is a considerable space around the inlet due to the upper inclined surface, the cap that covers the inlet is removed, and the neutralizing agent is put into the tank through the inlet. Can be easily performed.

  Moreover, in the said neutralization tank, the lower end of the introduction pipe which introduce | transduces electrolytically produced acidic water is made to face the bottom part vicinity of the V-shaped bottom part of a tank. For this reason, the lower end portion of the introduction pipe is located at the deepest part of the neutralizing agent layer accommodated in the tank, and the electrolytically generated acidic water flowing out from the lower end opening of the introduction pipe is While being neutralized uniformly in the sump layer, the neutralizing agent is consumed without any spots and does not decrease. Furthermore, the neutralizing agent maintains a stable height with respect to the lower end opening of the introduction pipe, and can efficiently neutralize the electrolytically generated acidic water with a small amount of the neutralizing agent. .

  In addition, since the upper end of the introduction pipe is open, it also functions as an overflow pipe. When the lower end opening of the introduction pipe is clogged with a neutralizing agent, the electrolytic pipe introduced into the introduction pipe is used. The generated acidic water is allowed to overflow into the tank from the upper end opening of the introduction pipe, and the backflow from the electrolytically generated acidic water introduction pipe to the drain line side can be prevented.

  Further, in the neutralization tank, a structure in which a drain pipe for draining the electrolytically generated alkaline water is connected to the introduction pipe so that the electrolytically generated acidic water and the electrolytically generated alkaline water are selectively introduced into the tank. ing. For this reason, the electrolytically generated alkaline water introduced into the tank of the neutralization tank can function as a neutralizing solution for neutralizing the electrolytically generated acidic water. Consumption can be reduced.

  In addition, in the said neutralization tank, when the bottom part of a tank employ | adopts the structure of a V-shaped bottom part, if it supports in the support stand which has a V-shaped receiving part and accommodates in a case, the neutralization tank Can be supported in a stable state. Further, in a neutralization tank mainly composed of a tank formed at the V-shaped bottom, if a drainage port is provided at the V-shaped bottom of the tank, the water remaining in the tank can be drained efficiently. The work efficiency during maintenance can be improved.

  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. . 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. It does not react with the hydrating agent and is drained through the drainage pipe 36c as it is.

  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 42b and 42c 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. 5 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 the electrolytically generated water to be dispensed by the consumer, and passes the selected electrolytically generated water through a dedicated extraction line. Make it pour 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 excess electrolytically generated acidic water that has flowed into the neutralization tank 25 is calculated from the generated flow rate, and the consumption of the neutralizing agent in the neutralization tank 25 is calculated from the excess amount of electrolytically generated acidic water. 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.

  Therefore, in the present invention, the configuration of the neutralization tank 25 provided in the electrolyzed water generating apparatus has the greatest feature, and FIGS. 6 and 7 show the neutralization tank 25. The neutralization tank 25 is received by the receiving portion 26 a of the support base 26 erected in the case main body 11 and stored in the case main body 11. The receiving portion 26a for receiving the tank 25a of the support base 26 has a V-shaped side section. For this reason, since the said neutralization tank 25 functions in the state (refer FIG. 7) received by the V-shaped receiving part 26a of the support stand 26, below, the V-shaped receiving part of the support stand 26 is shown. Assuming that the state received by 26a is the basic form of the neutralization tank 25, the shape, structure and function of the neutralization tank 25 will be described.

  The neutralization tank 25 is mainly composed of a tank 25a having a rectangular cross section in the cross section and closed at the top and bottom, and the upper side surface 25a1 of the tank 25a is formed on an inclined surface that is inclined downward. The lower surface 25a2 is formed in a horizontal plane. Accordingly, in the tank 25a, when the support base 26 is received by the V-shaped receiving portion 26a, the lower side surface 25a2 and the front side surface 25a3 of the tank 25a form a V-shaped bottom. Therefore, hereinafter, the bottom portion is referred to as a V-shaped bottom portion 25A.

  The tank 25a is provided with a neutralizing agent charging port 25b for charging the neutralizing agent on the upper side surface (hereinafter referred to as the upper inclined surface 25a1), and the charging port 25b is a large-diameter port. It is covered with a large-diameter cap 25b1. In addition, in the tank 25a, the left side surface 25a4 is provided with an introduction port 25c1 to which a drain pipe 36a for draining excess electrolytically generated acidic water is connected, and the right side surface 25a5 has An outlet portion 25c2 to which a drain pipe 36c for draining the processing liquid neutralized in the tank 25a is connected is provided. A drainage pipe 36b for draining excess electrolytically generated alkaline water is also connected to the introduction port 25c1.

  In the neutralization tank 25, an introduction pipe 25d is provided inside the tank 25a so as to stand up at a position rearward of the neutralization agent inlet 25b. The introduction pipe 25d has an upper end and a lower end opened, and the upper and lower substantially central portions thereof are connected to the introduction port portion 25c1. In this connected state, the introduction pipe 25d is erected in the tank 25a so as to be biased to a portion behind the charging port 25b, with the lower pipe facing the vicinity of the bottom of the V-shaped bottom 25A. Therefore, in a state where a predetermined amount of the neutralizing agent F is accommodated in the tank 25a, the lower pipe portion enters the deepest portion of the neutralizing agent F layer.

  In the electrolyzed water generating apparatus, the neutralizing agent F accommodated in the tank 25a of the neutralizing tank 25 is gradually consumed according to the neutralization treatment of the excess electrolyzed acidic water. When the consumption amount of F reaches a predetermined amount, it is necessary to replenish the neutralizing agent F into the tank 25a. The replenishment work of the neutralizing agent F into the tank 25a is performed in a state where the door 12 is opened and the front opening of the case body 11 is opened.

  In the electrolyzed water generating apparatus, when the front opening of the case body 11 is opened, the neutralization tank 25 housed in the case body 11 appears on the front of the operator. In the neutralization tank 25 that appears, the upper inclined surface 25a1 of the tank 25a that is the main body of the neutralization tank 25 is inclined downward, and the charging port 25b formed in the upper inclined surface 25a1 is provided by the operator. The cap 25b1 that covers the charging port 25b is removed because it is located in an easy-to-see part and a considerable space is secured around the charging port 25b due to the upper inclined surface 25a1. The operation of charging the neutralizing agent F into the tank 25a through the charging port 25b can be easily performed.

  Moreover, in the said neutralization tank 25a, the lower end of the introduction pipe 25d which introduce | transduces electrolytically produced acidic water faces the bottom part vicinity of 25 A of V-shaped bottom parts. For this reason, the lower end portion of the introduction pipe 25d is located at the deepest part of the layer of the neutralizing agent F accommodated in the tank 25a, and the electrolytic generation flowing out from the lower end opening portion of the introduction pipe 25d. The acidic water is uniformly neutralized in the neutralizing agent F layer, and the neutralizing agent F is consumed without any spots and is not reduced.

  Furthermore, the neutralizing agent F maintains a stable height with respect to the lower end opening of the introduction pipe 25d, and the electrolytically generated acidic water is efficiently neutralized with a small amount of the neutralizing agent F. be able to.

  Further, since the upper end of the introduction pipe 25d is open, it also functions as an overflow pipe. When the lower end opening of the introduction pipe 25d is clogged with the neutralizing agent F, the introduction pipe 25d is used. The electrolytically generated acidic water introduced into 25d is allowed to overflow into the tank 25a from the upper end opening of the introducing pipe 24d to prevent backflow from the electrolytically generated acidic water introducing pipe 25d toward the drain lines 36a and 36b. it can.

  Moreover, in the said neutralization tank 25, the structure which connects the drainage pipe line 36b of electrolysis production | generation alkaline water to the introduction pipe 25d is taken, and electrolysis production | generation acidic water and electrolysis production | generation alkaline water are selectively introduce | transduced in the tank 25a. Like to do. Therefore, in the neutralization tank 25, the electrolytically generated alkaline water introduced into the tank 25a can function as a neutralizing solution for neutralizing the electrolytically generated acidic water and is originally used. The consumption of the neutralizing agent F should be reduced.

  In addition, in the said neutralization tank 25, since the bottom part of the tank 25a is formed in V-shaped bottom part 25A, if it supports on the V-shaped receiving part 26a of the support stand 26, the neutralization tank 25 will be in the stable state Can be supported. Further, since the drain port 25e is provided in the V-shaped bottom portion 25A, water remaining in the tank 25a can be drained efficiently, and the work efficiency during maintenance of the neutralization tank 25 can be improved.
