Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an undersink type electrolyzed water generator.
The present invention relates to a device for freely discharging anode water, cathode water and the like from a predetermined faucet by using an operation knob arranged on a faucet.

[0002]

2. Description of the Related Art Anodic water and cathodic water discharged from an electrolyzed water generator are used as astringent water and drinking water, respectively. Therefore, the main body of the electrolyzed water generator and the spout are integrally configured, and an integrated electrolyzed water generator that has all the functions of the electrolyzed water generator by itself is provided near the sink of the kitchen equipment, if desired. BACKGROUND ART Anode water and cathode water are discharged and used. However, in such a method of use, the arrangement of the electrolyzed water generator,
In particular, the water supply and drainage pipes intersect with each other, and the routing of the pipes is not only unsightly, but also difficult to use.

Particularly when the sink is a system kitchen, the exposure of the apparatus main body and piping is not desirable from an aesthetic point of view, and it is difficult to handle. Therefore, while the device body such as the electrolyzed water generator is built into the sink of the kitchen equipment, a faucet made of metal or resin is provided near the sink so that the built-in device body and the faucet can be installed. There is an under-sink type electrolyzed water generator that controls the apparatus main body by using an operating knob attached to a water faucet and controls the discharge of anode water and cathode water from the apparatus main body.

The current demand for the under-sink type electrolyzed water generator is not always secured in a quantity suitable for mass production. For this reason, it is general that the integrated electrolyzed water generator is partially modified and installed in the undersink. In such a system, the main body of the device, which is composed of an electrolyzer and the like, branches off from the water pipe of the undersink to obtain city water, and a dedicated faucet is fixed near the sink of the sink, with a dedicated pipe between them. In addition, wiring is provided between the faucet and the device body for remote control of the device body, and by operating the operation knob provided on the faucet, the operation knob, the remote control wiring, and the control circuit on the device body And the operation signal information is transmitted so that the apparatus main body performs a predetermined operation. As a result, the apparatus main body can be freely controlled by operating the operation knob of the water faucet, which makes the apparatus easy to use.

An example of installation of such an undersink type electrolyzed water generator is shown in FIG.

In the figure, an electrolyzed water generator body 6 is installed below a sink 2 of a sink 1. The water supplied to the generator body 6 is configured to be supplied from a branch portion 5 attached to a pipe from the water supply pipe 4 to the mixed water faucet 3. The power of the generator body 6 is supplied via the power plug 7. Anode water and cathode water obtained by electrolysis of the supply water flow through the anode water pipe 12 and the cathode water pipe 13 to reach the faucet 8, and desired anode water or cathode water is supplied through the water discharge pipe 10. In addition, undesired water is discharged from the spout 26. These water supplies are freely controlled by the operation knob 9 attached to the water faucet 8, and the control signal is conveyed by the control wiring 11 connecting the water faucet 8 and the generator body 6.

The main body of the electrolyzed water generator is activated carbon for adsorbing and removing substances such as odor and chlorine in city water that are not suitable for drinks, and filters such as hollow fibers for preventing fine substances that form turbidity and bacteria. A water purifier consisting of a water purifier, an adding device that adds components such as calcium that give water a taste to the purified water that has passed through the water purifier, and positive and negative electrodes are inserted into the anode chamber and the cathode chamber that are divided by the partition wall, and a direct current is applied. It consists of an electrolyzer that electrolyzes the city water that flows in, a control unit that controls them, and a power supply.

The water electrolyzed in the electrolyzer is discharged from a pipe opening provided on the opposite side of the anode chamber and cathode chamber of the electrolyzer. Then, it passes through the pipes 12 and 13 to reach the faucet. However, when a positive potential is applied to the positive electrode and a negative potential is applied to the negative electrode for a long time to continue electrolysis, the calcium ions contained in the city water are discharged from the mouth of the cathode chamber and the cathode chamber due to the increase in pH due to electrolysis. Precipitates as calcium carbonate or calcium hydroxide in the inside of piping. For this reason, a potential opposite to the above potential is applied to each electrode, that is, so-called polarity reversal, so that calcium carbonate and calcium hydroxide which are deposited in the tube opening and the inside of the pipe are pickled to prevent the deposition. During this polarity reversal period, due to the reversal of the electrodes, the anode water flows in the water discharge flowing from the cathode chamber to the cathode water discharge side, and the cathode water flows in the water discharge flowing from the anode chamber to the anode water discharge side. At this time, in order to prevent negative anolyte water opposite to the desired negative anolyte water from flowing to the water outlet, it is preferable that the electric motor is operated in accordance with polarity reversal, preferably with a time lag corresponding to the delay of water flow after polarity reversal. A cross line valve for reversing the water passage is provided by a valve or a solenoid valve to continuously obtain the desired negative and positive water.

FIG. 5 is a schematic view showing the structure of the apparatus main body provided with such a cross line valve, and FIG. 5 (a) is a view showing the original operating state, that is, normal operation, and FIG. )
FIG. 4 is a diagram showing a case of so-called polarity reversal in which the polarity of the current applied to the negative anode is reversed. In the figure, members such as a water purifier in the flow path of the water supply side pipe 24 for supplying water to the electrolysis tank 25 are omitted, but these members may be installed.

In the figure, a cross line valve 20 synchronized with the reversal of the polarity of the current applied to the cathode and anode is a cathode chamber 1 of an electrolytic cell 25 which is divided by an ion-permeable partition wall 21 of the apparatus body 6.
4 and the outflow pipes 16 and 17 of the anode chamber 15 are provided at the outflow rear portions, and the flow paths are inverted in synchronization with the inversion of the polarity as described above.

That is, during normal operation shown in FIG. 5A, the anode water discharged from the outflow pipe 17 from the anode chamber 15 in which the anode 22 is disposed is discharged from the anode chamber discharge port 19, while the cathode 23 is discharged. Cathode water that discharges the outflow pipe 16 from the cathode chamber 14 in which is disposed is discharged from the cathode chamber water discharge port 18. On the other hand, in the polarity reversal operation shown in FIG. 5B, the polar chamber is reversed from that in the normal operation, and the anode chamber 1
Anode water discharged from the outflow pipe 16 from 5 is reversed by the cross line valve 20 and discharged from the anode chamber water discharge port 19,
The cathode water discharged from the cathode chamber 14 through the outflow pipe 17 is reversed by the cross line valve 20 and discharged from the cathode chamber water outlet 18. Therefore, by adopting a circuit system for automatically reversing the crossline valve 20 in accordance with the polarity reversal, in the case of the polarity reversal, one of the cathode and anode water is discharged from a predetermined water discharge port as in the normal operation. It is possible to discharge continuously without changing the water outlet.

As a result, while calcium carbonate, calcium hydroxide, etc. deposited in the electrolytic cell and the pipe leading to the crossline valve are washed by polarity reversal, desired electrolytic water is continuously supplied from a predetermined spout for a long period of time. It can be stably supplied and used.

However, in the undersink type electrolyzed water generator in which the apparatus main body and the water faucet tool are connected by a pipe, they are provided after the apparatus main body. Since the pipes 12, 13 and the faucet 8 are placed outside the operation of the cross line valve 20, calcium carbonate or calcium hydroxide may be deposited. For built-in equipment such as an undersink type electrolyzed water generator, the above piping 1
2 and 13 are long and are often used in a maintenance-free state for a long period of time, and in this case, the above-mentioned deposits significantly impair the reliability of the apparatus.

[0014]

Therefore, according to the present invention, the first crossline valve is installed in the main body of the apparatus, the second crossline valve is installed in the faucet, and the second crossline valve is operated. By providing a circuit in which the first crossline valve does not operate, the undersink type electrolytic water generator responds to the polarity reversal without any special modification to the control circuit of the integrated electrolytic water generator, Make the valve reversible. As a result, an attempt is made to provide an undersink-type electrolyzed water generator that reduces the maintenance of pipes such as calcium ions accumulated in the pipes through which the cathode water discharged from the cathode chamber passes and does not require maintenance for a long period of time. It is a thing.

[0015]

Therefore, the first aspect of the present invention is described.
The under-sink type electrolyzed water generator of is equipped with a device body such as an electrolyzer that electrolyzes inflowing city water by inserting positive and negative electrodes into the anode chamber and the cathode chamber divided by the ion-permeable partition wall, respectively. Installed inside the sink, a tube mouth is provided in the anode chamber and the cathode chamber of the electrolytic cell, and one end of a pipe for flowing out the anode water discharged from the anode chamber of the tube mouth and the cathode water discharged from the cathode chamber is described above.

When the electrode inversion signal trigger t ₀ that instructs the inversion timing is generated, at the same time, the electrode inversion signal rises, continues for a predetermined time t, and electrolysis is performed in the inversion state. The second crossline valve starts to operate with a delay of t _{1 from the} trigger t ₀ . This delay t ₁ can be freely set by a known delay circuit.

Therefore, the delay t ₁ can be set freely according to the running water retention time of the pipes 12 and 13. Moreover, by adopting a variable system in which the delay time can be freely changed from the outside, it is possible to operate the second crossline valve by delaying the reversal of the anode and anode of the electrolytic cell according to the length of the apparatus main body and the faucet. Therefore, even if the pipes 12 and 13 are drawn around for a long time, water can be continuously discharged from the predetermined water discharge port without mixing the cathode and anode water.
