2. Description of the Related Art A conventional electrolyzed water generator will be described with reference to FIG. FIG. 9 is a schematic configuration diagram of a conventional electrolytic water generation device. As shown in FIG. 9, a conventional electrolyzed water generating apparatus includes an electrolyte tank 1, a pump 2, a mixing tank 3, an electrolysis tank 4, four four-port valves 5a, 5b, 5c, and 5d.
It is basically composed of two tanks 6a, 6b, faucets 7a, 7b provided corresponding to each tank 6, a power supply unit 8, and a control unit 9. Further, the electrolytic cell 4 is provided with a first electrode 42 and a second electrode 43.

[0003] Each component will be described in detail below. The electrolyte tank 1 is a tank for storing an aqueous solution of an electrolyte, and specifically, an aqueous solution of sodium chloride, an aqueous solution of potassium chloride, or the like can be used. The pump 2 pumps up the electrolyte aqueous solution stored in the electrolyte tank 1 and discharges it to the mixing tank 3.

The mixing tank 3 mixes raw water (generally tap water) introduced from the outside with an aqueous electrolyte solution discharged from the pump 2 and discharges the mixed liquid to the electrolytic tank 4.

The electrolytic cell 4 electrolyzes the mixed liquid discharged from the mixing tank 3 by applying a voltage to the first electrode 42 and the second electrode 43 by using the power supply unit 8 to obtain an acidic liquid. (Hereinafter referred to as “acidic water”) and water exhibiting basic liquidity (hereinafter referred to as “alkaline water”), which are discharged through different routes. That is, the electrolytic cell 4
For example, while the acidic water is being discharged from the water channel X in FIG. 9, the alkaline water is discharged from the water channel Y, and while the alkaline water is being discharged from the water channel X, the acidic water is discharged from the water channel Y. Is discharged. In the following description, the acidic water and the alkaline water are collectively referred to as “electrolyzed water”.

[0006] The three-port valves 5a and 5b are provided corresponding to the water passages X and Y, respectively.
“a” discharges the electrolytic water discharged from the electrolytic tank 4 through the water channel X to either the water channel P or the water channel Q in accordance with an instruction (an instruction to switch the water channel) input from the control unit 9 described later. Things.

The second three-port valve 5b is connected to the electrolytic cell 4
Discharges the electrolyzed water discharged through the water channel Y to one of the water channels P ′ and Q ′ in response to an instruction (an instruction to switch the water channel) input from the control unit 9 described later.

[0008] The three-port valve 5c, 5d
a, 5b and the tanks 6a, 6b,
The third three-port valve 5c discharges the electrolytic water supplied from the water channel Q or the water channel Q 'to the tank 6b in response to an instruction (an instruction to switch the water channel) input from the control unit 9 described later, or Drain it. The fourth three-port valve 5d discharges or drains the electrolytic water supplied from the water channel P or the water channel P 'to the tank 6a in accordance with an instruction input from the control unit 9 described later. is there. The specific configuration of the three-port valve 5 will be described later.

The tank 6a is connected to the water channel from the fourth three-port valve 5d, and stores the electrolytic water discharged through the water channel P and the water channel P '. Here, as described later, the control unit 9 controls the three-port valves 5a and 5b so that the electrolyzed water discharged through the water channel P and the water channel P 'is always acidic water. Are mainly for storing acidic water.

The tank 6b is connected to the water channel from the third three-port valve 5c, and stores the electrolytic water discharged through the water channel Q and the water channel Q '. Similarly to the tank 6a, the control unit 9 described later mainly stores alkaline water in the tank 6b.

The faucets 7a and 7b discharge water stored in the corresponding tank 6a or 6b to the outside according to a user's instruction.
It is like an electronically controlled faucet or sprinkler.

The power supply unit 8 applies voltages having different polarities to the first electrode 42 and the second electrode 43 of the electrolytic cell 4. Further, the power supply unit 8 reverses the polarity of the voltage applied to the first electrode 42 and the second electrode 43 in accordance with an instruction from the control unit 9 described later.

The control section 9 has a timer, and outputs an instruction to invert the polarity to the power supply section 8 every time the timer measures a predetermined time. When the controller 9 outputs an instruction to invert the polarity to the power supply unit 8, the controller 9 outputs an instruction to switch the water channel to each of the two three-port valves 5a and 5b.

Further, the control unit 9 switches the water paths of the two three-port valves 5c and 5d for a certain period of time immediately after outputting the instruction to invert the polarity to the power supply unit 8, so that the electrolytic cell 4 discharges. It is designed to drain water.
This is to prevent the electrolyzed water having the deteriorated function from entering the tank 6 immediately after the electrode is inverted until the electrolyzed water has a constant liquid property.

That is, for example, when the acidic water is discharged from the water channel X and the alkaline water is discharged from the water channel Y, the control unit 9 guides the acidic water to the tank 6a,
In order to guide the alkaline water to b, an instruction to guide the acidic water discharged through the water channel X to the water channel P is output to the first three-port valve 5a connected to the water channel X, and connected to the water channel Y. The second 3-port valve 5b outputs an instruction to guide the alkaline water discharged through the channel Y to the channel Q '.

When the control section 9 outputs an instruction to invert the polarity to the power supply section 8, the control section 9 switches the three-port valves 5c and 5d to drainage, and further switches the water paths of the three-port valves 5a and 5b, temporarily temporarily. The electrolytic water discharged from the electrolytic cell 4 is drained.
Later, when the electrolytic cell 4 discharges an alkaline water of an appropriate value through the water channel X and discharges an acidic water of an appropriate value through the water channel Y, the water channels of the three-port valves 5c and 5d are switched again. Alkaline water discharged through channel X is transferred to channel Q
The acidic water discharged through the water channel Y is guided to the tank 6a through the water channel P '.

Here, the reason that the control section 9 reverses the polarity at regular intervals is that if a voltage of the same polarity is always applied, the control section 9 precipitates from the mixed solution on the surface of the electrode of the electrolytic cell 4. This is for preventing the solid (scale) from adhering, reducing the efficiency of the electrolysis and the performance of the electrolyzed water from deteriorating, and also preventing the electrode from deteriorating. Also, the three-port valve 5 is provided, and the control unit 9 outputs an instruction to switch the water channel, because the electrolyzed water having different liquid properties is mixed in each tank 6 and the performance of the electrolyzed water is deteriorated. The purpose of this is to prevent any of the tanks 6 from containing acidic water or alkaline water, and to enhance convenience.

Here, a specific structure of the three-port valve 5 will be described with reference to FIG. FIG. 10 is an explanatory diagram illustrating a specific structure of the three-port valve 5. As shown in FIG. 10, the three-port valve 5 has a T-shaped body 51 having an inlet A and two outlets B and C, and a water channel b or a water channel c in response to an external instruction. And a plunger 52 that operates so as to close it.

The T-shaped body 51 is basically formed with a T-shaped water passage, eliminates water leakage from the end of the plunger 52, and reliably supplies water guided from the inlet A to either the outlet B or C. Water passages b and c, which are sufficiently narrower than the cross section of the plunger 52, are formed at the center so that discharge can be performed to either side.
They respectively follow the discharge ports B and C. In addition, the water discharged through the inlet A is guided to the center, and the plunger 5
2 and through a gap formed between the opening of the water channel b and the water channel c, through the water channel b or the water channel c,
It reaches the discharge port B or the discharge port C.

The plunger 52 is an electromagnetically controlled solenoid, and operates so as to close one of the water passages b and c of the T-shaped body 52 in response to an external instruction. The portion of the plunger 52 that contacts the openings of the water passages b and c is formed of rubber or the like so as not to leak water.
Further, the gap with the opening is arranged to be narrow.

That is, in FIG. 9, the water passage X is connected to the inlet A in the first three-port valve 5a, and the water passage Y is connected to the inlet A in the second three-port valve 5b. 3
In the port valve 5c, the water channel connecting the water channel Q and the water channel Q 'is connected to the inlet A. In the fourth three-port valve 5d, the water channel connecting the water channel P and the water channel P' is connected to the inlet A. I have.

In FIG. 9, the discharge port B of the first three-port valve 5a and the discharge port C of the second three-port valve 5b are connected to the water passages Q and Q ', respectively. Outlet C,
The discharge port B of the second three-port valve 5b is
P '. Further, the third three-port valve 5c

Next, the operation of the conventional electrolyzed water generator will be described. Tap water introduced from the outside is mixed in the mixing tank 3 with the aqueous electrolyte solution pumped up by the pump 2 from the electrolyte tank 1, and is guided to the electrolytic tank 4 as a mixed solution. Electrolyzer 4
Voltages having different polarities are applied to the first electrode 42 and the second electrode 43 from the power supply unit 8, and the mixed solution guided from the mixing tank 3 is electrolyzed in the electrolytic tank 4, It becomes acidic water and alkaline water. For example, acidic water is discharged through a water channel X, and alkaline water is discharged through a water channel Y.

The first three-port valve 5a receives the acidic water discharged through the water channel X at the inlet A, guides the acid water to the discharge port C, and discharges the acid water to the fourth three-port valve 5d through the water channel P. I do. Then, the fourth three-port valve 5d receives the acidic water discharged through the water channel P at the inlet A, and discharges the acid water C for a predetermined time.
And drain. When the fixed time has elapsed, the control unit 9
The fourth three-port valve 5d is switched according to the instruction from, and the acidic water is discharged from the discharge port B to the tank 6a.

The second three-port valve 5b receives the alkaline water discharged through the water channel Y at the inlet A, guides the alkaline water to the discharge port C, and connects the alkaline water to the third three-port valve 5c through the water channel Q '. Discharge. Then, the third three-port valve 5c receives the alkaline water discharged through the water channel Q 'at the inlet A, guides the alkaline water to the discharge port C for a certain time, and drains the water. After the elapse of the certain time, the third three-port valve 5c is switched by an instruction from the control unit 9 to discharge the alkaline water from the discharge port B to the tank 6b. Then, the acidic water is stored in the tank 6a, and the alkaline water is stored in the tank 6b.

When the timer of the control section 9 finishes measuring a predetermined time, the control section 9 outputs an instruction to invert the polarity to the power supply section 8 and the two 3-port valves 5a and 5a.
An instruction to switch the waterway is output to b. Then, the power supply unit 8 reverses the polarity of the voltage applied to each electrode of the electrolytic cell 4,
Alkaline water comes to be discharged through water channel X,
Further, the acidic water is discharged through the water channel Y.

Immediately after reversing the polarity, the liquid properties of these electrolyzed waters are deteriorated. Therefore, even if the first three-port valve 5a and the second three-port valve 5b are switched, the electrolytic water is not immediately discharged to the tanks 6a and 6b, and the third three-port valve 5c and the fourth 3 port valve 5
d is switched to drain the electrolyzed water for a certain period of time immediately after the polarity is reversed. Eventually, when the liquidity of the electrolyzed water becomes sufficient, the control unit 9 switches the third three-port valve 5c and the fourth three-port valve 5d so as to discharge the electrolyzed water from the wastewater to the tanks 6a and 6b. Output instructions.

The third 3-port valve 5c is connected to the control unit 9
In response to an instruction input from the tank 6b, the alkaline water guided from the water channel Q is received by the inlet A and guided to the outlet B by the tank 6b.
The alkaline water is discharged. Also, the fourth
Similarly, the 3 port valve 5d receives the acidic water led from the water channel P 'at the inlet A and guides it to the outlet B, and the tank 6a
The acidic water is discharged.

In this way, the tank 6a always stores acidic water, and the tank 6b always stores alkaline water.

Further, the function realizing means may be realized by a plurality of circuits, or the plurality of function realizing means may be realized by a single circuit.

Before describing the contents of the present invention, the objects of the present invention will be summarized. In the electrolyzed water generating apparatus, the alkaline water discharged from the electrolysis tank is a fluid for attaching the scale, which is a cause of obstructing the switching operation by the switching valve. The acidic water discharged from the electrolytic cell has the property of dissolving and removing its scale.By inverting the polarity of the voltage applied to the electrodes of the electrolytic cell, the acidic water is supplied to the pipe connected to the two outlets of the electrolytic cell. It is known that water and alkaline water flow alternately, and the scale adheres very little to the pipe.

The switching valve guides the acidic water and the alkaline water flowing from the pipe to the dedicated outlet. However, scale adheres to the flow path through which only the alkaline water flows and narrows the flow path. It has become. But,
Since the flow path connected to the tank for storing the alkaline water derived from the switching valve has a relatively large diameter, the alkaline water does not stop flowing even if some scale adheres. However, the flow path at the outlet port portion on the alkaline water storage tank side inside the switching valve (the flow path through which only alkaline water flows inside the switching valve) is usually
Since the diameter is not so large, if the scale adheres to the port portion, the switching operation of the switching valve may not be performed smoothly.

Therefore, in the present invention, the sliding portion of the switching valve is eliminated, the scale is prevented from adhering to the outlet port portion of the alkaline water, and the diameter of the flow path through which only the alkaline water flows is made relatively large. Thus, the switching operation can be stably performed for a long period of time.

The switching valve of the present invention comprises a first movable pipe through which acidic water or alkaline water flows, a second movable pipe through which alkaline water or acidic water flows, and a discharge port of the first or second movable pipe. The alkaline water outlet hole into which the alkaline water flows out, the acidic water outlet hole into which the acidic water flowing out from the discharge port of the first or second movable pipe flows, and the alkaline water outlet hole flows out from the discharge port of the first or second movable pipe. It comprises a drainage outlet hole into which drainage flows, and direction control means for controlling the direction of the discharge ports of the first and second movable pipes. The outlets of the first and second movable pipes and the alkaline water outlet, the acidic water outlet, and the drain outlet have a non-contact structure. The diameter is designed to be larger than the diameter of the first and second movable pipes. This makes it possible to provide a structure that does not have the operating contact surface and the sliding surface in the flow path switching portion of the valve, and the switching operation can be performed stably for a long time.

Further, the electrolyzed water generating apparatus of the present invention is provided with the above-mentioned switching valve, and the control means for controlling the reversal of the polarity of the electrode in the electrolytic cell is provided with a first or second movable pipe according to the reversal of the polarity. This is an electrolyzed water generating apparatus that controls a direction control means so as to guide acidic water flowing out from a discharge port to an acidic water outlet, alkaline water to an alkaline water outlet, and drainage to a drain outlet. Thereby, the structure which does not have the working contact surface and the sliding surface in the flow path switching portion of the valve can be performed, and the switching operation in the electrolyzed water generation device can be stably performed for a long time.

Further, in the electrolyzed water generating apparatus of the present invention, when the operation of inverting the polarity of the electrode in the electrolytic cell is started, the direction control means sets the discharge ports of the first and second movable pipes to the drain outlet for a specific time. This is an electrolyzed water generation device that performs control such that the water is directed and then switches the direction of the discharge port of the movable pipe. This makes it possible to properly discharge the wastewater discharged due to the reversal of the electrode polarity when the flow path is switched by the switching valve.
