The load of the electrolyzed water generator 3 mounted on the top wall 20T is supported by the main body case 2C. The main body case 2C and the tank 20 may be integrally formed, or the tank 20 itself may be configured to also serve as the main body case 2C. The water storage device 2 is arranged adjacent to the sink 100 of the sink, for example.

The tank 20 has an inlet 21 for receiving electrolytically acidic water, an intake port 22 for taking out electrolytically acidic water stored in the tank 20, and electrolytically acidic water exceeding a predetermined water level H in the tank 20. It is provided with a drainage port 23 for discharging the water. The drainage port 23 is arranged above the intake port 22. As a result, a large amount of electrolytically acidic water can be stored in the tank 20.

FIG. 3 shows a schematic configuration of the electrolyzed water generator 3. FIG. 4 shows the electrical configuration of the electrolyzed water generator 3. The electrolyzed water generator 3 produces electrolyzed hydrogen water and electrolyzed acidic water by electrolyzing water. The electrolyzed water generator 3 includes a water purification cartridge 31 and an electrolytic cell 32.

The water purification cartridge 31 is connected to the hose 12 via the water channel 61. The water purification cartridge 31 purifies the raw water supplied from the hose 12 and supplies it to the electrolytic cell 32.

An electrolytic cell 40 is formed in the electrolytic cell 32. The electrolytic chamber 40 is divided into a first electrolytic chamber 40a and a second electrolytic chamber 40b by a diaphragm 43. The water purification cartridge 31 and the electrolytic chamber 40 are connected to each other via a water channel 62. The water channel 62 branches in two directions and guides the purified water purified by the water purification cartridge 31 to the first electrolytic chamber 40a and the second electrolytic chamber 40b.

The purified water flowing into the electrolytic chamber 40 is electrolyzed in the electrolytic chamber 40. Inside the electrolytic chamber 40, a first feeding body 41 and a second feeding body 42 having different polarities are arranged so as to face each other.

A diaphragm 43 is disposed between the first feeding body 41 and the second feeding body 42. The diaphragm 43 is composed of, for example, a polytetrafluoroethylene (PTFE) hydrophilic membrane.

The diaphragm 43 divides the electrolytic chamber 40 into a first electrolytic chamber 40a on the first feeding body 41 side and a second electrolytic chamber 40b on the second feeding body 42 side. The first feeding body 41 and the second feeding body 42 are electrically connected via the diaphragm 43.

Of the first feeding body 41 and the second feeding body 42, one is applied as an anode feeding body and the other is applied as a cathode feeding body. Water is supplied to both the first electrolytic chamber 40a and the second electrolytic chamber 40b of the electrolytic chamber 40, and a DC voltage is applied to the first feeding body 41 and the second feeding body 42, so that water is supplied in the electrolytic chamber 40. Electrolysis occurs.

For example, in the state shown in FIG. 3, the first feeding body 41 is positively charged, and the first electrolytic chamber 40a functions as an anode chamber. On the other hand, the second feeding body 42 is charged with a negative charge, and the second electrolytic chamber 40b functions as a cathode chamber. That is, in the second electrolytic chamber 40b, reducing electrolytic hydrogen water in which hydrogen gas generated by electrolysis is dissolved is generated, and in the first electrolytic chamber 40a, electrolytic acidic water generated by electrolysis is generated.

The polarity of the voltage applied to the first feeding body 41 and the second feeding body 42 is controlled by the control means 51. By appropriately switching the polarities of the first feeding body 41 and the second feeding body 42, the opportunities for the first feeding body 41 and the second feeding body 42 to function as the anode feeding body or the cathode feeding body are equalized. As a result, adhesion of the scale to the first feeding body 41, the second feeding body 42, and the like is suppressed.

Hereinafter, unless otherwise specified, the case where the first feeding body 41 functions as an anode feeding body and the second feeding body 42 functions as a cathode feeding body will be described below.

A flow path switching valve 63 is provided on the downstream side of the electrolytic cell 32. The flow path switching valve 63 switches the flow path on the downstream side of the electrolytic cell 32, that is, the connection between the first electrolytic cell 40a and the second electrolytic cell 40b and the water channels 64 and 65. The flow path switching valve 63 is controlled by the control means 51.

The control means 51 has, for example, a CPU (Central Processing Unit) that executes various arithmetic processes, information processing, and the like, a program that controls the operation of the CPU, and a memory that stores various information. Various functions of the control means 51 are realized by a CPU, a memory, and a program.

The control means 51 controls the polarity of the voltage applied to the first feeding body 41 and the second feeding body 42 in synchronization with the operation of the flow path switching valve 63, whereby the first feeding body 41 and the second feeding body 51 are controlled. Electrolyzed hydrogen water can be discharged from the water channel 64 and electrolytic acid water can be discharged from the water channel 65 while suppressing the adhesion of the scale to the water channel 64 and the like.

The water channel 64 is connected to the hose 13. As a result, the electrolytic hydrogen water generated in the second electrolytic chamber 40b on the cathode side is returned to the faucet 11 via the hose 13.

The water channel 65 is fixed to a frame (not shown) of the electrolyzed water generator 3 or the like, and extends toward the tank 20 of the water storage device 2. An electrolyzed water discharge port 65a is provided at the tip of the water channel 65. The electrolyzed water discharge port 65a communicates with the water inlet 21 of the tank 20. As a result, the electrolytically acidic water generated in the first electrolytic chamber 40a on the anode side is collected in the tank 20 and can be reused.

The water level H is set below the electrolyzed water discharge port 65a of the electrolyzed water generator 3. As a result, the water overflowing from the tank 20 is suppressed from flowing back to the electrolyzed water discharge port 65a.

The water storage device 2 includes a water channel 29 that connects the electrolyzed water discharge port 65a and the water inlet 21. The electrolyzed acidic water discharged from the electrolyzed water discharge port 65a is more reliably collected in the tank 20 by the water channel 29.

The electrolyzed water generator 3 can discharge electrolyzed acidic water via the water channel 64 and the hose 13, for example, by the control means 51 switching the polarity of the voltage applied to the first feeding body 41 and the second feeding body 42. Is. At this time, the electrolyzed hydrogen water is discharged from the electrolyzed water discharge port 65a. That is, the electrolyzed water discharge port 65a selectively discharges either electrolyzed acidic water or electrolyzed hydrogen water.

It is desirable that the top wall 2T of the water storage device 2 is formed in a shape corresponding to the bottom of the electrolyzed water generation device 3. For example, as shown in FIGS. 1 and 2, the top wall 2T is formed with a recess 80 corresponding to the bottom 33 of the electrolyzed water generator 3. Further, the recess 80 is formed with a hole 81 into which the protruding leg portion 34 of the electrolyzed water generator 3 is fitted. As a result, when the electrolyzed water generating device 3 is mounted on the mounting portion 28 of the water storage device 2, the bottom portion 33 is guided by the recess 80, and the electrolyzed water generating device 3 can be easily installed. Then, by fitting the leg portion 34 and the hole 81, the electrolyzed water generating device 3 is accurately positioned at a predetermined position of the water storage device 2.

Further, for example, as shown in FIGS. 1 and 2, the electrolyzed water discharge port 65a may be configured to be housed in the water inlet 21 or the water channel 29 extending upward from the water inlet 21. In the present embodiment, the electrolyzed water generator 3 is accurately positioned with respect to the water storage device 2 by fitting the leg portion 34 and the hole 81, so that the electrolyzed water generator 3 is the mounting portion 28 of the water storage device 2. The electrolyzed water discharge port 65a is housed in the water inlet 21 or the water channel 29 extending upward from the water inlet 21, and the electrolyzed water discharge port 65a and the water inlet 21 are easily connected. Therefore, troublesome pipe connection work becomes unnecessary.

Therefore, it is desirable that a valve device (not shown) is provided in the water channel 29 connected to the electrolyzed water discharge port 65a. The valve device functions to prevent the electrolyzed hydrogen water generated by the electrolyzed water generating device 3 from entering the tank 20. The valve device can be configured, for example, by a three-way valve. A bypass channel (not shown) for bypassing the electrolyzed hydrogen water discharged from the electrolyzed water discharge port 65a to the sink 100 is connected to the valve device. As a result, only electrolytically acidic water can be stored in the tank 20. A Duckbill valve or the like may also be applied to the valve device. In this case, the bypass channel is arranged in the channel 29 on the upstream side of the valve device.

The bypass channel can be formed on the top wall 2T of the water storage device 2 or the top wall 20T of the tank 20. For example, a bypass channel can be constructed by providing a concave groove in the top wall 2T or the like. Further, a bypass channel may be configured by raising a part of the top wall 2T or the top wall 20T.

The valve device can be configured to manually switch water channels. By manually using the valve device, the configuration of the water storage device 2 can be simplified and the cost can be reduced.

Further, the valve device can also be configured by a solenoid valve powered by electric power. In this case, the valve device can be controlled automatically.

FIG. 5 is a block diagram of the water storage device 2 including the automatically controlled valve device. The electrolyzed water generator 3 corresponding to the water storage device 2 is shown in FIG.

The electrolyzed water generator 3 has a transmission means 53 for transmitting a signal regarding the nature of the water flowing through the water channel 29. The "signal regarding the properties of water" is a signal for identifying whether the water flowing through the water channel 29 is electrolyzed hydrogen water, electrolyzed acidic water, or neutral water (purified water) that has not been electrolyzed. .. The water flowing through the water channel 29 is water discharged from the electrolyzed water discharge port 65a, and the control means 51 has the polarity of the voltage applied to the first feeding body 41 and the second feeding body 42 and the flow path switching valve 63. The property of the water is specified from the state, and the signal is transmitted from the transmission means 53.

On the other hand, the water storage device 2 has a receiving means 72 and a control means 71. The transmitting means 53 and the receiving means 72 are configured to be communicable by wire or wirelessly. The receiving means 72 receives the above signal output from the transmitting means 53 of the electrolyzed water generating device 3.

The control means 71 is configured by a CPU or the like like the control means 51. The control means 71 identifies the nature of the water flowing through the water channel 29 based on the signal received by the receiving means 72, and controls the valve device 73. As a result, the valve device 73 is automatically controlled, and the electrolytic hydrogen water is prevented from flowing into the tank 20.
