Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 shows a schematic configuration of an electrolytic water producing apparatus 1 according to an embodiment of the first invention and a hydrogen-water server 100 according to an embodiment of the second invention. The numeric server 100 includes an electrolytic water generating device 1 and is a device for storing the hydrogen generated by the electrolytic water producing device 1 so that the hydrogen can be supplied from time to time. The drinking water provided by the drinking water server 100 can be used as water for drinking or cooking.

The electrolytic water producing apparatus 1 includes an electrolytic bath 4, an exhaust means 24, and a flow rate adjusting valve 25. The electrolytic water producing apparatus 1 also functions solely as an apparatus for generating electrolytic water in addition to a form applied as a main part of the water-reducing server 100. The exhaust means 24 and the flow control valve 25 are provided on the downstream side of the electrolytic bath 4.

The electrolytic bath 4 electrolyzes the supplied water to generate hydrogen water. The electrolytic cell 4 has an electrolytic chamber 40, a positive electrode feeder 41, a negative electrode feeder 42, and a diaphragm 43. The electrolytic chamber 40 is divided by the diaphragm 43 into an anode chamber 40A on the anode current collector 41 side and a cathode chamber 40B on the cathode current collector 42 side.

The positive electrode current collector 41 and the negative electrode current collector 42 are formed, for example, with a platinum plating layer formed on the surface of a mesh metal such as expanded metal made of titanium or the like. The net cathode positive electrode 41 and the negative electrode current collector 42 can disperse the water evenly on the surface of the diaphragm 43 while supporting the diaphragm 43 therebetween, Promotes electrolysis. Platinum plated layer prevents oxidation of titanium.

As the diaphragm 43, for example, a solid polymeric material composed of a fluoric resin having a sulfonic acid group is suitably used. On both sides of the diaphragm 43, a plated layer made of platinum is formed. The plating layer of the diaphragm 43 and the anode feeder 41 and the cathode feeder 42 are in contact with each other and are electrically connected. The diaphragm 43 passes electrolytically generated ions. The positive electrode feeder 41 and the negative electrode feeder 42 are electrically connected through the diaphragm 43. When the diaphragm 43 made of a solid polymer material is applied, the concentration of dissolved hydrogen can be increased without increasing the pH value of the hydrogenated water.

By electrolysis in the electrolytic chamber 40, oxygen gas is generated in the anode chamber 40A and hydrogen gas is generated in the cathode chamber 40B. In the present invention, hydrogen gas generated in the cathode chamber (40B) is dissolved in electrolytic water in the cathode chamber (40B) to generate hydrogen gas. Hydrogen generated by such electrolysis is referred to as "electrolytic water. &Quot;

The exhaust means 24 and the flow rate regulating valve 25 are connected to the anode chamber 40A. The exhaust means 24 includes a so-called gas ventilation valve which separates and discharges the oxygen gas from the electrolytic water generated in the anode chamber 40A. Owing to this, the oxygen gas generated in the anode chamber (40A) is prevented from staying on the surface of the anode current collector (41). Therefore, the electrolytic water is sufficiently supplied to the surface of the anode current collector 41, and electrolysis is efficiently performed, and it becomes possible to increase the concentration of dissolved hydrogen.

The flow control valve 25 is provided on the downstream side of the exhaust means 24. As a result, the flow regulating valve 25 prevents the discharge of oxygen gas from being disturbed. The flow rate adjusting valve 25 adjusts the amount of water supplied to the anode chamber 40A. For example, the flow rate regulating valve 25 restricts the water flowing out of the anode chamber 40A, thereby limiting the amount of water supplied to the anode chamber 40A. As a result, most of the water supplied to the electrolytic bath 4 becomes hydrogen supplied to the cathode chamber 40B, and water can be effectively used.

The electrolytic water producing apparatus 1 includes flow rate sensors (flow rate detecting means) 27A and 27B. The flow rate sensor 27A is provided on the upstream side of the anode chamber 40A and detects the amount of water supplied to the anode chamber 40A. The flow rate sensor 27B is provided on the upstream side of the cathode chamber 40B and detects the amount of water supplied to the cathode chamber 40B.

2 shows the electrical configuration of the numeric data server 100. As shown in FIG. The numeric server (100) includes a control unit (6) and a current detection unit (44).

The control unit 6 controls each part of the positive electrode current collector 41, the negative electrode current collector 42, and the like. The control unit 6 includes, for example, a CPU (Central Processing Unit) for executing various kinds of arithmetic processing, information processing, and the like, and a memory for storing various information and a program for performing operations of the CPU. A current detection means 44 is provided in the current supply line between the anode class 41 and the control unit 6. [ The current detecting means 44 may be provided in the current supply line between the negative electrode feeder 42 and the control unit 6. [ The current detecting means 44 detects the electrolytic current I supplied to the positive electrode feeder 41 and the negative electrode feeder 42 and outputs an electric signal corresponding to the value to the controller 6.

The control unit 6 controls the DC voltage applied to the positive electrode class 41 and the negative electrode class 42 based on the electric signal output from the current detection unit 44, for example. More specifically, the control unit 6 controls the anode current collector 41 and the cathode current collector 41 so that the electrolytic current I detected by the current detecting unit 44 becomes a desired value, 42 by a feedback control. For example, when the electrolytic current I is too large, the controller 6 decreases the voltage, and when the electrolytic current I is too small, the controller 6 increases the voltage. As a result, the electrolytic current I supplied to the positive electrode current collector 41 and the negative electrode current collector 42 is appropriately controlled.

An electric signal is input to the control unit 6 from the flow rate sensors 27A and 27B. The flow rate sensor 27A detects the quantity of water supplied to the anode compartment 40A and outputs an electric signal corresponding to the quantity to the control unit 6. [ The flow rate sensor 27B detects the quantity of water supplied to the cathode chamber 40B and outputs an electric signal corresponding to the quantity to the control section 6. [

The control unit 6 controls the opening degree of the flow rate adjusting valve 25. [ The control unit 6 is a mode for controlling the flow rate control valve 25, and has a first mode and a second mode. In the first mode, the control unit 6 sets the opening degree of the flow control valve 25 to the first opening degree. During normal operation, the control unit 6 controls the flow rate regulating valve 25 in the first mode. That is, the opening degree of the flow rate adjusting valve 25 is initially set to the first opening degree. On the other hand, in the second mode, the control unit 6 sets the opening degree of the flow rate adjusting valve 25 to the second opening degree larger than the first opening degree.

The switching from the first mode to the second mode can be performed based on, for example, an electric signal inputted from the flow rate sensor 27A.

More specifically, when the quantity detected by the flow rate sensor 27A is equal to or greater than a predetermined threshold value, it can be estimated that sufficient electrolytic water is filled in the anode compartment 40A and electrolysis is normally taking place in the electrolytic bath 4. [ Therefore, the control unit 6 controls the flow regulating valve 25 to have the first opening degree, and limits the quantity of the water supplied to the anode chamber 40A to the first quantity.

On the other hand, when the quantity detected by the flow sensor 27A is less than the threshold value, it can be estimated that oxygen gas stays in the anode chamber 40A, which may interfere with electrolysis in the electrolyzer 4. [ Therefore, the control unit 6 switches the mode for controlling the flow rate adjusting valve 25 from the first mode to the second mode, and controls the opening degree of the flow rate adjusting valve 25 to be the second opening degree. As a result, the amount of water supplied to the anode chamber 40A is increased, and the oxygen gas staying therein is discharged from the anode chamber 40A by the water flow. Therefore, sufficient electrolytic water is filled again in the anode chamber 40A, and efficient electrolysis in the electrolytic bath 4 is resumed.

The operation in the second mode lasts for a predetermined time when it is considered that the staying oxygen gas is discharged from the anode chamber 40A. The time can be determined in advance by experiment or the like. When the time elapses, the control unit 6 switches the mode for controlling the flow rate adjusting valve 25 from the second mode to the first mode, and controls the opening degree of the flow rate adjusting valve 25 to be the first opening degree.

The control unit 6 may be configured to control the opening degree of the flow rate adjusting valve 25 by comparing the quantity detected by the flow rate sensor 27A with the quantity detected by the flow rate sensor 27B. For example, when the quantity detected by the flow rate sensor 27A is significantly smaller than the quantity detected by the flow rate sensor 27B, the control unit 6 sets the mode for controlling the flow rate adjustment valve 25 to the first Mode to the second mode.

Based on the relationship between the electrolytic voltage applied to the positive electrode current collector 41 and the negative electrode current collector 42 and the electrolytic current I detected by the current detecting means 44, The opening degree of the valve 25 may be controlled.

More specifically, when the ratio of the electrolytic current I to the electrolytic voltage is equal to or greater than the predetermined threshold value, it can be estimated that the electrolytic cell 4 is filled with sufficient electrolytic water in the anode chamber 40A, and efficient electrolysis is taking place. Therefore, the control unit 6 controls the flow regulating valve 25 to have the first opening degree, and limits the quantity of the water supplied to the anode chamber 40A to the first quantity.

On the other hand, when the ratio of the electrolytic current I to the electrolytic voltage is less than the above-mentioned threshold value, it can be estimated that the oxygen gas stays in the anode chamber 40A and the electrolysis in the electrolytic bath 4 may be interrupted. Therefore, the control unit 6 switches the mode for controlling the flow rate adjusting valve 25 from the first mode to the second mode, and controls the opening degree of the flow rate adjusting valve 25 to be the second opening degree. As a result, the amount of water supplied to the anode chamber 40A increases, and the oxygen gas staying therein is discharged from the anode chamber 40A by the water flow. The return from the second mode to the first mode is the same as described above.

The controller 6 may be configured to control the opening degree of the flow rate adjusting valve 25 by comparing the electrolysis current I detected by the current detecting means 44 with a predetermined threshold value. The control unit 6 also combines the determination based on the quantity detected by the flow rate sensor 27A and the judgment based on the electrolysis current I detected by the current detection means 44, ) May be controlled.

As shown in Figs. 1 and 2, the water-supply server 100 further includes a water filter 2, a tank 3, and an operation unit 5. [

The water filter (2) purifies the water supplied to the tank (3). The water filter (2) is configured to be exchangeable by attaching / detaching to / from the main body of the water supply server (100). The water filter (2) is installed in the upstream-side water intake path (11) of the tank (3). The raw water (raw water) is supplied to the water intake path 11. Although tap water is generally used as raw water, besides, for example, well water, ground water and the like can be used. The intake path 11 has a water inlet valve 21. The inlet valve (21) controls the flow rate to the hydrophone server (100).

The water filter 2 of the present embodiment includes a pre-filter 2A, a carbon (activated carbon) filter 2B, and a hollow fiber membrane filter 2C. The pre-filter 2A, the carbon (activated carbon) filter 2B, and the hollow fiber membrane filter 2C are configured to be exchangeable by attaching / detaching to / from the main body of the hydrophobic server 100, respectively. The pre-filter 2A is disposed at the most upstream side, for example, removes a material of 0.5 mu m or more contained in raw water. The carbon filter 2B is disposed on the downstream side of the pre-filter 2A, and removes the material passing through the pre-filter 2A by adsorption. The hollow fiber membrane filter 2C is disposed on the downstream side of the carbon filter 2B and removes substances having passed through the pre-filter 2A and the carbon filter 2B, for example, 0.1 mu m or more.

The tank (3) stores the water that has passed through the water filter (2). The control unit 6 appropriately maintains the amount of water stored in the tank 3 by controlling the opening and closing of the water inlet valve 21 based on the electric signal outputted from the water sensor 31. [ As shown in Fig. 1, the water quantity sensor 31 is installed in the upper part of the tank 3. The quantity sensor 31 has a float portion floating in water. In this embodiment, the water quantity sensor 31 is provided on the upper part of the tank 3 and outputs an electric signal to the control unit 6 when the water storage amount of the tank 3 becomes approximately full.

The control unit 6 controls the water inlet valve 21 to be in the open state when the electric signal of the above-mentioned full water status is not input from the water amount sensor 31. [ As a result, water is appropriately replenished to the tank 3, and the water storage amount is appropriately maintained.

The operation unit 5 shown in Fig. 2 has a switch operated by a user or a touch panel (not shown) for detecting capacitance. The user can set the operation mode of the numeric server 100 to be described later, for example, by operating the operation unit 5. [ When the user operates the operation unit 5, the operation unit 5 outputs a corresponding electric signal to the control unit 6. [ The control unit 6 controls each part of the numerical controller 100 in accordance with the electric signal inputted from the operation unit 5. [

As shown in Fig. 1, a circulation path 12 is provided between the tank 3 and the electrolytic bath 4. In Fig. The circulation path 12 is a flow path for circulating water between the tank 3 and the electrolytic bath 4. [ The water stored in the tank 3 is supplied to the electrolytic bath 4 through the circulation path 12 and returned to the tank 3 through the circulation path 12 after being electrolyzed.

The circulation path 12 includes circulation paths 12a, 12b and 12c arranged on the upstream side of the electrolytic bath 4 and circulation paths 12d and 12e arranged on the downstream side of the electrolytic bath 4. [ The circulation path 12a is connected to the tank 3 at one end on the upstream side and branches to the circulation paths 12b and 12c at the other end side on the downstream side. A pump 22 is installed in the circulation path 12a. The pump 22 drives the water in the circulation path 12 to circulate in the circulation path 12. Electrolysis occurs in the electrolytic cell 4 while circulating water in the circulation path 12, so that the dissolved hydrogen concentration of the water stored in the tank 3 is increased.

The circulation path 12b is connected to the anode chamber 40A on the downstream side and the circulation path 12c is connected to the cathode chamber 40B on the downstream side. A flow rate sensor 27A is provided in the circulation path 12b and a flow rate sensor 27B is provided in the circulation path 12c. The flow rate sensor 27A detects the flow rate of water flowing into the anode chamber 40A. The flow rate sensor 27B detects the flow rate of water flowing into the cathode chamber 40B. The circulation path 12d is connected to the anode chamber 40A at one end of the upstream side and to the tank 3 at the other end side of the downstream side. The circulation path 12e is connected to the cathode chamber 40B at one end of the upstream side and to the tank 3 at the other end side of the downstream side.

The exhaust means 24 and the flow rate regulating valve 25 are disposed in the circulation path 12d from the anode chamber 40A to the tank 3 in this embodiment. Because of this, the path of the water flowing out to the anode chamber 40A coincides with the discharge path of the oxygen gas, so that the oxygen gas can be efficiently discharged. In addition, the exhaust means 24 and the flow control valve 25 are integrated on the downstream side of the anode chamber 40A, so that the configuration of the hydrogen-water server 100 can be simplified.

In the circulation of hydrogenated water, the control unit 6 controls the driving voltage of the pump 22. At this time, the control unit 6 controls the driving voltage of the pump 22 while monitoring the flow rate detected by the flow rate sensors 27A and 27B. This causes the hydrogen water stored in the tank 3 to circulate through the circulation path 12 between the tank 3 and the electrolytic bath 4 and the electrolytic water is filled in the anode chamber 40A and the cathode chamber 40B. In addition, the control unit 6 applies an electrolytic voltage to the positive electrode current collector 41 and the negative electrode current collector 42. Thus, the electrolytic water supplied to the electrolytic bath 4 is further electrolytically decomposed, so that the dissolved hydrogen concentration of the hydrogen water stored in the tank 3 can be kept high. When the flow rate detected by the flow sensors 27A and 27B is less than a sufficient value in some circumstances, the electrolytic voltage applied to the positive electrode feeder 41 and the negative electrode feeder 42 is stopped. Thus, the electrolytic water can be prevented from being applied while the electrolytic water in the electrolytic bath 4 is not sufficiently supplied.

As shown in Fig. 1, the hydrogen-powered server 100 has a soil-water path 13 connected to the cathode chamber 40B. The groundwater passage 13 is a channel for discharging the hydrogen generated in the cathode chamber 40B. The groundwater passage 13 of this embodiment is branched at one end side of the circulation path 12e and connected to the cathode chamber 40B. As a result, the configuration of the numeric server 100 is simplified.

A flow path switching valve 23 is disposed at a branch point 12f at which the groundwater path 13 branches off from the circulation path 12e. The so-called three-way valve can be applied to the flow-path switching valve 23. The flow path switching valve 23 is controlled by the control unit 6 in accordance with the operation mode of the water supply server 100 and supplies part or all of the flow path on the downstream side of the branch point 12f to the circulation path 12e, (13). That is, in the electrolytic water generation mode, all of the flow path on the downstream side of the branch point 12f becomes the circulation path 12e. In the water jetting mode, part or all of the flow passage downstream of the branch point 12f is switched to the groundwater passage 13. This makes it possible to switch the flow path with a simple configuration. The groundwater passage 13 may be directly connected to the cathode chamber 40B.

A water jetting spout (13a) is provided at the tip end side of the ground water passage (13). Below the water jetting spout 13a, a space for placing the cup 500 and the like is formed, and a collection tray 13b for collecting water flowing from the cup 500 is installed.

When the hydrogen stored in the tank 3 is consumed, the control unit 6 opens the intake valve 21 and supplies it to the tank 3 from the intake path 11, based on the electric signal outputted from the water amount sensor 31 Water is replenished. At this time, since the dissolved hydrogen concentration of the hydrogen water stored in the tank 3 drops, the control unit 6 controls the circulation path 12 between the tank 3 and the electrolytic bath 4 so that the hydrogen water stored in the tank 3 And electrolyzed in the electrolytic bath 4 while circulating again, thereby increasing the concentration of dissolved hydrogen.

As shown in Fig. 1, a cooling device 7 is connected to the tank 3. The cooling device 7 cools the refrigerant and supplies it to the outer wall of the tank 3 to cool the tank 3. The operation of the cooling device (7) is controlled by the control unit (6). As a result, the number of the hydrogen stored in the tank 3 is cooled to a desired temperature by the cooling device 7. Therefore, it becomes possible to provide the cold water from time to time according to the demand of the user, and the ease of use of the water minority server 100 is improved.

In this embodiment, the hydrogen water stored in the tank 3 under the control by the control unit 6 is periodically replaced. At the time of replacing the hydrogenated water, the hydrogen water stored in the tank 3 is discharged first, and then fresh water is supplied to the tank 3 from the water intake path 11.

The tank 3 is connected to a drainage path 14 for discharging hydrogenated water. In this embodiment, the tank 3 and the drainage path 14 are connected through a part of the circulation path 12a. The tank 3 and the drainage path 14 may be directly connected to each other.

A drain valve (26) is provided in the drainage path (14). The drain valve 26 is controlled by the control unit 6 to open and close. When the drain valve 26 is opened, the hydrogen water stored in the tank 3 is discharged from the drain hole 14a.

The collection tray 13b is connected to the drainage path 14 through a path 13c. The water collected by the collection tray 13b is discharged from the drainage path 14 via the path 13c.

As shown in Fig. 1, the tank 3 is provided with a heater (heating means) 8 for heating water. The heater (8) generates heat by the Joule heat and heats the water stored in the tank (3). A heater (heating means) 8A is provided between the tank 3 of the circulation path 12 and the pump 22. The heater 8A is installed in a part of the pipe constituting the circulation path 12. [ The heater 8A generates heat by joule heat to heat the water in the circulation path 12. [ The heaters 8 and 8A are controlled by the control unit 6. Only one of the heaters 8 or 8A may be applied as the heating means.

The control unit 6 controls the heaters 8 and 8A to heat the water stored in the tank 3 and the water in the circulation path 12. [ As a result, hot water is generated in the tank 3 and the circulation path 12, and the inside of the tank 3 and the circulation path 12 is sterilized by hot water, thereby suppressing the propagation of bacteria and the like.

A bypass valve 28 is provided in the circulation path 12d. The bypass valve 28 is arranged in parallel with the flow rate regulating valve 25. The bypass valve 28 is controlled by the control unit 6 to cooperate with the operation of the heaters 8 and 8A. When the bypass valve 28 is opened, the number of the circulation paths 12d is increased, and the number of the hot water supplied to the anode chamber 40A is increased. The bypass valve 28 may be omitted if the adjustment range of the flow rate control valve 25 is sufficiently wide.

The numeric number server 100 is an operation mode which includes an electrolytic water generation mode for generating hydrogen water by electrolysis and storing the electrolyzed water in the tank 3 and a water jet mode for discharging the hydrogen water stored in the tank 3 , The tank 3, and the electrolytic bath 4, and the like.

3 and 4 show the operation of each part of the water-reducing server 100 and the flow of water in the electrolytic water production mode. In these drawings, a region filled with water is shown as a light hatch (the same applies in Figs. 5 to 7).

In the electrolytic water generation mode, the flow path of the flow path switching valve 23 on the side of the tank 3 is opened, and the flow path on the side of the ground surface 13 is closed. Further, the drain valve 26 is closed, and the inlet valve 21 is properly opened and closed in accordance with the amount of water stored in the tank 3.

3 shows a state in which the control unit 6 controls the flow rate adjusting valve 25 in the first mode and a state in which the control unit 6 controls the flow rate adjusting valve 25 in the second mode in FIG. .

3, in the first mode, the bypass valve 28 is closed, the flow rate regulating valve 25 is narrowed to the first opening degree # 1, the flow rate of the circulation path 12d is limited have.

When an electrolytic voltage is applied to the positive electrode feeder 41 and the negative electrode feeder 42 in the state that the anode chamber 40A and the negative electrode chamber 40B are filled with water, electrolysis is started in the electrolyzer 4, Hydrogen water is produced in the chamber 40B. At this time, the controller 6 performs feedback control of the electrolytic voltage so that the electrolytic current detected by the current detecting means 44 becomes a desired value. When the driving voltage is applied to the pump 22, water in the circulation path 12 is fed by the pump 22 and circulated in the circulation path 12 including the tank 3 and the electrolytic bath 4 , And the hydrogen water generated in the cathode chamber (40B) is recovered in the tank (3).

At this time, the oxygen gas generated by the electrolysis in the anode chamber 40A moves upward through the circulation path 12d and is discharged from the exhaust means 24. [ The oxygen gas discharged from the exhaust means 24 is opened to the outside atmosphere of the hydrogen-water server 100 because the internal space of the numeric server 100 is not sealed from the outside.

The flow of the electrolytic water returning from the anode chamber 40A to the tank 3 is reduced to the first opening degree # Is limited. Therefore, the electrolytic water in the anode chamber 40A, which does not contribute to the increase in the dissolved hydrogen concentration, does not return to the tank 3 substantially, and thus the dissolved hydrogen concentration of the hydrogen water in the tank 3 becomes high efficiently. In addition, the electrolytic water flowing into and out of the anode compartment 40A can suppress the retention of the oxygen gas in the anode compartment 40A, and the electrolysis in the electrolytic bath 4 can be efficiently performed. In the electrolytic water production mode, the water supply server 100 may be configured so that electrolytic water in the anode chamber 40A does not return to the tank 3 by completely closing the flow control valve 25. [ In this case, the water utilization efficiency is further increased.

In some cases, oxygen gas adheres to the surface of the positive electrode active material layer 41 and stays in the anode chamber 40A. In such a case, since the electrolysis does not occur in the region where the oxygen gas is adhered, the electrolysis efficiency in the electrolytic bath 4 is lowered.

Therefore, in this embodiment, as shown in Fig. 4, the opening amount of the flow control valve 25 is set to the second opening degree (# 2) to increase the amount of water supplied to the positive electrode current collector 41. [ As a result, the staying oxygen gas moves along with the electrolytic water flowing into and out of the anode compartment 40A and discharged from the anode compartment 40A. Therefore, sufficient electrolytic water is filled again in the anode chamber 40A, and efficient electrolysis in the electrolytic bath 4 is resumed.

5 shows the operation of each part of the numeric server 100 and the flow of water in the jet mode. In the water jetting mode, the flow path of the hydrogen water having passed through the cathode chamber 40B by the flow path switching valve 23 is switched from the state of the first mode shown in Fig. That is, in the water jetting mode, the flow path on the side of the tank 3 is closed and the flow path on the side of the water surface flow path 13 is opened. In this state, the pump 22 is driven so that the hydrogen water that has passed through the cathode chamber 40B flows into the groundwater passage 13 and is discharged from the water jetting spout 13a. At this time, the controller 6 may be configured to apply an electrolytic voltage to the positive electrode current collector 41 and the negative electrode current collector 42.

6 and 7 show the operation of each part of the hydrophobic server 100 and the flow of water in a time series in the sterilization mode. In the sterilization mode, water in the tank 3 and the circulation path 12 is heated and circulated, and each part of the tank 3, the electrolyzer 4, the circulation path 12, and the like is sterilized by heating. As a result, propagation of bacteria and the like is suppressed in each part of the numeric server 100. The sterilization mode is executed periodically under the control of the control unit 6. [ For example, the sterilization mode is performed every day at night, for example. The time zone in which the sterilization mode is executed can be appropriately set by, for example, operating the operation unit 5 by the user.

In the sterilizing mode, the states of the flow path switching valve 23 and the drain valve 26 by the control unit 6 are controlled in the same manner as the original electrolyzed water generating mode. That is, the flow path of the flow path switching valve 23 on the side of the tank 3 is opened, and the flow path on the side of the ground surface 13 is closed. Then, the drain valve 26 is closed. In the sterilization mode, the flow control valve 25 and the bypass valve 28 are opened. When the pump 22 is driven in this state, sufficient hot water is also supplied to the anode compartment 40A, the flow rate sensor 27A, and the circulation paths 12b and 12d so that the anode compartment 40A, the flow rate sensor 27A, Circulation paths 12b and 12d, etc. are heated by hot water and sterilized.

The flow rate of the hot water supplied to the anode chamber 40A is preferably set to be equal to the flow rate of the hot water supplied to the cathode chamber 40B. As a result, the same amount of hot water as the cathode chamber 40B is supplied to the anode chamber 40A, so that the anode chamber 40A and the circulation paths 12a and 12b can be sufficiently sterilized.

When the water stored in the tank 3 and the water in the circulation path 12 are heated by controlling the heaters 8 and 8A, the drain valve 26 is opened in advance and the water is discharged from the drain port 14a to the tank 3 A part of the stored water may be discharged. In this case, since the amount of water to be heated is small, heating can be completed with a small power in a short time.

Further, in this case, it is preferable that the hot water of the tank 3 in the sterilization mode includes water vapor. By filling the tank 3 with steam, the upper area of the tank 3, which is not immersed in hot water caused by the decrease in the storage amount of the tank 3, is sterilized by water vapor. For example, the water quantity sensor 31 and the upper wall 33 are sterilized by water vapor.

Further, in order to obtain sufficient sterilization effect in a short time, the temperature of the hot water is preferably 75 DEG C or higher, for example.

When the sterilization of the tank 3 and the electrolytic bath 4 is completed, the control unit 6 turns off the heaters 8 and 8A to terminate the heating and finish the driving of the pump 22. 7, the drain valve 26 is opened to discharge the hot water from the tank 3, the circulation path 12, the electrolytic bath 4, and the like. The flow path of the flow path switching valve 23 on the side of the tank 3 is closed and the flow path on the side of the ground water passage 13 is opened to discharge hot water from the water jetting path 13. [ At this time, the soil-water path 13 and the drain path 14 are sterilized by the hot water passing through the soil-water path 13 and the drain path 14. The hot water discharged from the water jetting spout 13a is collected by the collecting tray 13b and passes through the path 13c to reach the drainage path 14. [ As a result, the collection tray 13b and the path 13c are sterilized.

In the sterilization mode, the control unit 6 controls the driving voltage of the pump 22 while monitoring the flow rate detected by the flow sensors 27A and 27B. Therefore, the amount of the hot water flowing through the circulation path 12 and the electrolytic bath 4 is controlled by the control unit 6. The control unit 6 can grasp the progress of the sterilization progress of the circulation path 12 and the electrolytic bath 4 and appropriately terminate the sterilization mode based on the amount of the hot water flowing through the circulation path 12 and the electrolytic bath 4 . At the end of the sterilization mode, the control unit 6 stops the pump 22 and opens the flow rate adjusting valve 25 and the bypass valve 28. [ As a result, the hot water in the circulation paths 12b and 12d and the anode chamber 40A is discharged from the drainage path 14.

1, an ultraviolet LED (ultraviolet ray irradiating means) 34 is provided on the upper wall 33 of the tank 3 in this embodiment. The ultraviolet LED 34 is a light emitting diode controlled by the control unit 6 to emit ultraviolet rays. The inside of the tank 3 is sterilized by the ultraviolet rays irradiated from the ultraviolet LED 34. [ The ultraviolet LED 34 may be provided in the circulation path 12 or the electrolytic bath 4 in addition to the tank 3. The ultraviolet LED 34 may be turned on in the electrolytic water production mode and sterilization mode. During the operation of the numeric server 100, the ultraviolet LED 34 may be lit at all times or at regular intervals.

The pressurizing pump 203 pressurizes the hydrogen peroxide generated in the cathode chamber 40B of the electrolytic water producing device 1A to the reverse osmosis membrane module 204. The reverse osmosis membrane module 204 has a reverse osmosis membrane (not shown). The reverse osmosis membrane filters the water that has been pressurized by the pressurizing pump 203. In other words, the reverse osmosis membrane removes impurities such as metals, which are in a trace amount from the hydrogen-water fed by the pressurizing pump 203, and filters the hydrogen-containing water. The filtered water filtered through the reverse osmosis membrane is supplied to the diluter 300.
