Next, the operation of the conventional alkali ion water conditioner 3 configured as described above when generating the alkali ion water will be described below.

The user presses a mode selection button on the operation display section 33 to select and set an alkaline ionized water generation mode, an acidic ionized water generation mode or a purified water mode. Selects the desired pH intensity with the pH intensity setting button of the operation display section 33, and opens the faucet 1. Faucet 1
The raw water passed through from the water switch 2 passes through the water purification unit 17
In the raw water, impurities such as residual chlorine, total trihalomethane, mold odor, and general bacteria are removed, and a part of the calcium glycerophosphate or calcium lactate is dissolved in a calcium supply unit 19 through a flow rate sensor 18 to facilitate electrolysis. After being treated with water, water is passed through the electrolytic cell 20.

In the alkaline ionized water generation mode, the drain valve 25 and the drain solenoid valve 26 are closed, and the acidic water solenoid valve 2 is closed.
8 is an open state. That is, alkaline ionized water is discharged from the water discharge pipe 5, acidic ionized water is discharged from the acidic water discharge pipe 9 via the acidic water hose 6, and no water is discharged from the drain outlet 27. In the conventional alkali ion water conditioner 3, the ratio of the amount of water discharged from the water discharge pipe 5 to the amount of water discharged from the acidic water discharge pipe 9 is 4:
The loss resistance of the throttle unit 24 is adjusted to be 1.

In the acidic ion water generation mode, the drain valve 25
The acidic water electromagnetic valve 28 is in a closed state, and the drainage electromagnetic valve 26 is in an open state. That is, the acidic ionized water is discharged from the water discharge pipe 5, the alkaline ionized water is discharged from the drainage outlet 27 through the drainage outlet 27 of the drainage hose 10, and no water flows out of the acidic water discharge pipe 9.

In the water purification mode, the drain valve 26 and the acidic water valve 28 are both closed. That is, the purified water is discharged from the water discharge pipe 5, and the acidic water discharge pipe 9 and the drain outlet 2 are discharged.
No water comes out of 7.

On the other hand, AC1
00V is supplied, and a transformer and a control DC power supply in the power supply unit 31 generate a DC voltage and current necessary for electrolysis,
The electrode plates 22 and 2 of the electrolytic cell 20 are
3 is supplied with electric power necessary for electrolysis. At this time, if the electrode plate to which a relatively positive voltage is applied is an anode and the electrode plate to which a negative voltage is applied is a cathode, an anode chamber and a cathode chamber separated by a diaphragm 21 are formed in the electrolytic cell 20. In the alkaline ionized water generation mode, the electrode plate 2
3 serves as an anode, and the electrode plate 22 serves as a cathode. On the other hand, in the acidic ionized water generation mode, the electrode plate 22 functions as an anode, and the electrode plate 23 functions as a cathode. In the water purification mode, no voltage is applied to the electrode plates 22 and 23.

After the passage of the water, the controller 32 reads the signal of the flow sensor 18 and judges that the water is flowing when the flow rate level exceeds a certain amount. At this time, since the electrolysis conditions have already been set by pressing the generation mode selection button on the operation display section 33, the controller 32 applies a predetermined voltage to the electrode plates 22 and 23 for electrolysis in the electrolytic cell 20. To output an operation command. As a result, in the alkaline ionized water generation mode, the electrode plate 22 serves as a cathode and the electrode plate 23 functions as an anode, and the alkaline ionized water is discharged from the discharge pipe 5. In the acidic ionized water generation mode, the electrode plate 22 has the anode and the electrode plate. 23 serves as a cathode, and acidic ion water is discharged from the discharge pipe 5. Further, in the water purification mode, no voltage is applied to the electrode plates 22 and 23, and purified water is discharged from the discharge pipe 5.

In the cleaning operation of the electrode plates 22 and 23, when the flow rate sensor 18 detects the flow rate of the electrolysis-off flow rate or less in a state where the flow rate exceeds a certain fixed number of times or the accumulated flow rate used, the drain valve 2 is used.
6 and the acidic water electromagnetic valve 28 are closed. Therefore, by applying an electrolytic voltage of the opposite polarity to the electrode plates 22 and 23 used so far for a certain period of time, the scale made of calcium / magnesium or the like attached to the electrode plate 22 or 23 used as the cathode is reduced. After the removal, the remaining water in the electrolytic cell 20 from which the scale has eluted is discharged into the drainage solenoid valve 2.
6 is opened for a certain period of time, and is discharged from the drain outlet 27 through the drain hose 10. During the washing operation, since the water is stopped, the drain valve 25 is opened.

As described above, in each mode, only the acidic water is discharged from the acidic water discharge pipe 9 provided in the acidic water stand 7 at all times. That is, since the alkaline ionized water, the purified water, and the wastewater are not mixed, the acidic ionized water generated as a by-product in the alkaline ionized water generation mode can be effectively used.

[0018]

As described above, in the conventional alkali ion water conditioner, acidic ion water generated as a by-product in the alkaline ion water generation mode could be effectively used.

However, in order to realize effective use of the acidic ionized water, two hoses, an acidic water hose 6 and a drain hose 10, are required. For this reason, the acid water outlet and the drainage outlet are provided in two places in the sink, and in a kitchen where the area around the sink cannot be widened, the acid outlet and the drainage outlet are likely to interfere with washing work or the like. Therefore, although it is originally considered to be optimally installed around a kitchen sink, there is a problem that it is not suitable for the size of the sink and hinders the spread of alkali ion water purifiers.

Therefore, the present invention provides an alkali ion water conditioner which can effectively utilize acidic ion water generated as a by-product in the alkaline ion water generation mode and does not hinder washing work even when it is installed in a sink or the like. The purpose is to provide.

According to such a configuration, the acidic ion water generated as a by-product in the alkaline ion water generation mode can be effectively used, and the outlet of the drainage is included in a part of the acidic water stand. Since it can be installed in a sink or the like, it does not interfere with the washing operation.
