[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous electrolyzed water generator used by being connected to a tap water tap of a general household.

[0002]

2. Description of the Related Art Conventionally, there is a continuous electrolyzed water generator used by being connected to a tap tap. A water purifier that adsorbs and removes pollutants and organic substances contained in the raw water of tap water, as well as chlorine components, and assists the addition of chemicals to promote electrolysis of tap water or increase specific dissolved components in tap water. An ion-permeable diaphragm is provided inside the container that seals the raw water that has passed through at least one of the agent addition devices to divide it into a cathode chamber and an anode chamber, and a DC voltage is applied between the cathode inside the cathode chamber and the anode inside the anode chamber. The alkaline water discharged from the cathode chamber is used for drinking, and the acidic water discharged from the anode chamber is used for face washing water.

For example, in the continuous electrolyzed water producing apparatus shown in FIG. 3 and the apparatus of Kaikai Hai 3-12395, an inflow path, an outflow path, and an inflow / outflow path to an electrolytic cell, which are the components housed in the box 5, are provided. Centralized flow path control unit 1, which is a collection of a water pressure sensing water channel for activating the operation operation switch of the electrolytic cell according to a change in water channel and water pressure, and a drain port for removing unnecessary water.
Water purifier 4 that removes raw water pollutants, auxiliary agent adder 6 for adding an electrolysis accelerator to a portion of raw water that has passed through the water purifier, raw water that has passed through the adder, and does not pass through the adder The raw water is supplied to the electrolytic cell from the branch pipe 2 which mixes with the raw water, and electrolysis is carried out by means of varying the voltage applied to the electrode of the electrolytic cell (not shown) for varying the electrolytic strength or a mechanism for reversing the polarity, Alkaline water discharged from the chamber or acidic water discharged from the anode chamber is discharged through the water discharge pipe 3, and unnecessary water used for cleaning the polar chamber is discharged through the central flow path control unit.

FIG. 4 is an explanatory view showing the functions of the centralized flow path control unit and the branch pipe. When a water faucet (not shown) is opened, tap water flows into the pipe from the pipe opening 11 of the centralized flow path control unit 1. Then, the water exits the pipe mouth portion 12 and flows into the inside of the water purifier 4 through the inflow port, and the purified water exits the outflow port and flows into the pipe mouth portion 13. A part of the water flows out of the pipe opening portion 14 and flows into the vessel from the inflow portion of the auxiliary agent adding device 6, and the water to which the electrolysis accelerator is added exits the outflow port and goes to the electrolytic cell 7
It is sent from the anode chamber side inlet 15 into the tank. Further, another water flow exits the pipe opening portion 16 and is branched via the branch pipe 2 and sent into the tank from the cathode chamber side inlet port 17 or the anode chamber side inlet port 15. In the electrolysis tank 7, alkaline water and acidic water are continuously generated by electrolysis, alkaline water is taken out from the outlet 18, and acidic water is taken out from the outlet 19.
If desired, the respective discharged water taken out from the outflow port is taken out as it is, or taken out as required alkaline water or acidic water from the water discharge pipe 3 through a valve that reverses a flow path (not shown). Undesired water is drained from the pipe opening 20.

The generated water discharged from the electrolytic cell is changed in direct current voltage applied to the negative electrode or positive electrode to change the current flowing between the positive and negative electrodes to change the electrolytic strength and to be used as a beverage or a facial cleanser. It is possible to obtain spouted water having a suitable pH. Alternatively, the pH may be changed by mutually adjusting the amounts of water supplied to the cathode chamber and the anode chamber. For example, if the flow rate of water supplied to the cathode chamber is reduced while the flow rate of water supplied to the anode chamber is not controlled, the flow rate of acidic water discharged from the anode chamber is relative to the flow rate of alkaline water discharged from the cathode chamber. You can do a lot. Thereby, the pH of the alkaline water can be increased. On the contrary, if the flow rate of water supplied to the anode chamber is reduced while the flow rate of water supplied to the cathode chamber is not controlled, the flow rate of alkaline water discharged from the cathode chamber will be relative to the flow rate of acidic water discharged from the anode chamber. You can do more. This makes it possible to lower the pH of the acidic water.

As a result of clinical studies of acidic water, it has been known that a strong bactericidal effect can be obtained by adjusting the pH of the acidic water discharged from the anode chamber to 4 or less, preferably about 3.5. Has been. A user of an electrolyzed water generator desires to use such strongly acidic water even in a domestic electrolyzed water generator.

[0007]

Therefore, the present invention provides a mechanism for controlling the supply of water to the electrolytic cell to a central flow path control unit or a branch pipe so that a normal alkali used as a beverage or a face-washing liquid can be obtained. In addition to water or acid water, the above-mentioned attachment mechanism is operated as desired to control the amount of water discharged from the cathode chamber or the anode chamber to relatively increase the degree of electrolysis and facilitate strong electrolyzed water effective for sterilizing action. Is to be provided to.

[0008]

In order to achieve the object, the present invention has a direct current between the cathode and cathode electrodes of the cathode chamber and the anode chamber, which are divided by an ion-permeable diaphragm and in which the cathode and anode are inserted. Electrolyzed water generation for applying a voltage and for generating the generated water having a desired pH by the above-mentioned varying means by providing the applied voltage varying means for varying the electrolysis strength of the electrolytic cell and continuously electrolyzing the raw water flowing into the electrolytic cell. In the apparatus, a central flow path control unit for supplying water to each of the cathode and anode chambers or a branch pipe is provided with a valve body for changing the amount of water supplied to the cathode and anode chambers,
The gist of the invention is to change the opening / closing degree of the valve element to regulate the amount of water discharged from the cathode / anode chamber.

[0009]

[Function] In addition to varying the degree of electrolysis by means of varying the voltage applied to the electrolytic cell to obtain alkaline water or acidic water, a central flow path control unit or a branch pipe is provided with a valve body for changing the amount of water supplied to the cathode and anode chambers. In addition, the flow rate of water supplied to the cathode chamber is reduced by changing the degree of opening and closing of the valve body, while water is supplied without controlling the flow rate of water supplied to the anode chamber, or the flow rate of water supplied to the anode chamber is reduced to the cathode chamber. When water is supplied without controlling the flow rate of water supply, the flow rate of alkaline water or acid water discharged from the cathode / anode chamber can be relatively increased. As a result, the pH of the alkaline water or acidic water can be changed to strong alkaline water or strongly acidic water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a valve body for varying the amount of water supply and a variable member accommodating the valve body according to the present invention. Members having the same functions and mechanisms as those in FIGS. 3 and 4 are designated by the same reference numerals. The variable member is the central channel control unit tube opening 16
Also, it is used by being attached to the branch pipe 3, and the flow rate can be adjusted from the outer surface of the box body 5. The variable member valve body 30 is configured to be housed in the housing member 40. The valve body 30 has a rotary shaft 34 that engages with a hole 44 that is formed through the shaft center of the housing member in the vertical center portion thereof, a hole 36 that is formed from the outer peripheral surface 37 into the valve body internal space, and a valve. Rotating shaft 3 from the body internal space
There is a water flow hole 32 that opens in a direction parallel to 4. Disc 3
When 0 is stored inside the storage member 40, the water outlet 31
While the water supplied from the x direction of the arrow passes through the water flow hole 32, when the position of the hole 36 and the pipe mouth portion 46 coincide, part of the inflow water flows from the hole 36 to the pipe mouth portion 46. Pass in the direction of a. Further, another flow passes through the water flow hole 32 and flows out from the pipe mouth portion 48 in the direction of the arrow b through the space formed by the outer peripheral surface 37 and the holding member 33. A water leakage prevention member 35 such as an O-ring that prevents water leakage from the hole 44 is attached to the engagement portion 38 housed inside the boss portion 45.

When the rotary shaft 34 is rotated in the y direction shown by the arrow from the above-mentioned state, the positions of the hole 36 and the pipe opening 46 do not coincide with each other, and the flowing water passing through the arrow a is blocked or Can be reduced.

FIG. 2 shows another embodiment of the variable member according to the present invention. The valve body 50 has an outer peripheral surface 51 inside the storage member 60.
Is slidably held on the inner surface 61 of the storage portion of the storage member. When the valve element 50 moves the operating rod 52 in the direction of the arrow q, the hole 53 formed in the inner space of the outer peripheral surface 51 of the valve element is exposed in the space 62. The internal space leads to the tube opening 54. If the supply water shown by the arrow x flows into the pipe mouth portion 63, a part of the supply water flows out from the pipe mouth portion 54 shown by the arrow a and the other flows out from the pipe mouth portion 64 shown by the arrow b through the space 62.

When the operating rod 52 is driven in the direction of arrow p, the hole 53 is closed by the inner surface 61 of the accommodating portion, so that the supply water can be controlled to flow out from the pipe mouth portion 54. This allows the amount of alkaline water or acidic water discharged from the electrolytic cell to be freely controlled.

By changing the hole diameter or shape of the holes 36 and 53 in addition to the feed water flowing from the auxiliary agent adder 6 into the electrolytic cell, the amount of water discharged from the cathode and anode chambers can be controlled within a certain range without being completely blocked. It becomes possible to adjust. For example, it is possible to easily set the ratio of the spouting amount of the alkaline water and the acidic water, which was 2.5: 1, to about 1: 3.

As described above, the variable member mutually adjusts the amount of alkaline water or acidic water discharged from the husband of the cathode chamber or the anode chamber, thereby changing the pH other than the voltage applied to the positive and negative electrodes. Therefore, for example, by limiting the amount of acidic water to the amount of alkaline water, the pH of the acidic water is defined by the voltage applied to the negative and positive electrodes.
It can be lower than H.

In FIG. 2, the operating method of the operating rod is not particularly shown, but it can be driven in the pq directions by a driving member such as a blanker other than the manual method. Further, the same effect can be obtained by using a mechanical method or another electric method. In this operation, the valve bodies 30 and 50 can perform digital flow rate control or analog flow rate control having two flow rates. These are merely examples, and various modifications can be made within the scope of the present invention other than the embodiments described above.

[0017]

The mechanism for controlling the inflow water supplied to the electrolytic cell is operated by attaching the mechanism for controlling the inflow water to the centralized flow path control unit or the branch pipe, so that strong alkaline water or strong acidic water other than normal alkaline water or acidic water is operated. By operating water with a variable member, the amount of water discharged from the cathode chamber or the anode chamber can be controlled to relatively increase the electrolysis degree of one side.

The entire apparatus can be constructed compactly, and the maintenance and management after installation can be easily performed as a single component such as inspection and repair.
