[0004]
In FIG. 4, 1 is a raw water pipe such as tap water, 2 is a faucet, 3 is a built-in alkaline water conditioner main body connected to the raw water pipe 1 via the faucet 2. Reference numeral 4 denotes a water purification unit, which includes activated carbon that adsorbs residual chlorine in raw water and a hollow fiber membrane that removes general bacteria and impurities. 5 is a flow rate sensor for confirming water flow and instructing control to be described later, 6 is an electrolytic cell for electrolyzing water that has passed through the flow rate sensor 5, and 7 is a diaphragm that divides the electrolytic cell 6 into two to form an electrode chamber. 8 and 9 are electrode plates arranged in each electrode chamber formed by being divided into two by the diaphragm 7. 10 is a water flow pipe for passing water on the electrode plate 9 side, 11 is a water discharge pipe for discharging water on the electrode plate 8 side, and 12 is acid water in an acidic water pipe (to be described later) when acidic water flows into the water flow pipe 10. An electromagnetic valve (for acidic water) 13 for flowing water is an acidic water discharge pipe (for drainage) that discharges acidic water that has flowed into the water flow pipe 10. Further, 14 is a power-on plug, 15 is a power supply unit for changing the AC power from the power-on plug 14 to a DC power, 16 is a control means for controlling the operation of the built-in alkaline water conditioner, and 17 is a built-in alkaline water conditioner. The operation display part which displays an operation state is shown.
[0005]
Next, the control block of the built-in alkaline water conditioner will be described with reference to FIG. Reference numeral 18 denotes an MPU (micro processor unit) that gives an operation instruction to each control unit (to be described later) of the control means 16, 19 a flow rate detection unit that transmits a signal from the flow rate sensor 5 to the MPU 18, and 20 an operation content of the operation display unit 17.

It is a certain timer.
[0006]
Next, the operation of the built-in alkaline water conditioner will be described based on the schematic control flow of FIG. 4, FIG. 5 and FIG.
[0007]
When the user sets the alkaline water generation mode by the operation display unit 17 (STEP 1), the setting contents of the user and the current operation state of the built-in alkaline water conditioner are displayed on the operation display unit 17 (STEP 2). Next, when the user opens the faucet 2, the raw water passed through the faucet 2 is freed of impurities such as residual chlorine odors and general bacteria in the raw water by the water purification unit 4, and passes through the flow sensor 5. Water flow is detected by the flow rate detector 19. Here, it is sorted with and without water flow detection (STEP 3). When there is water flow detection, the control content is distributed according to the generation mode set by the user (STEP 4).
[0008]
When the user sets the alkaline water generation mode in STEP 1, the electromagnetic valve 12 (for acidic water) is opened (STEP 5), and the water that has passed through the flow sensor 5 is passed through the electrolytic cell 6. The water passed through the electrolytic cell 6 is electrolyzed in the electrolytic cell 6 in which the polarity and electrolysis strength of the electrode plates 8 and 9 are controlled by the electrolytic cell control unit 21 (STEP 6). Further, the alkaline water generated in the electrolytic cell 6 is discharged through the water discharge pipe 11. On the other hand, the acidic water generated in the electrolytic cell 6 is drained through the electromagnetic valve 12 (for acidic water) and the acidic water discharge pipe 13.
[0009]
When the user sets the water purification mode in STEP 1, the electromagnetic valve 12 (for acidic water) is closed (STEP 7). Since the electrolytic cell 6 stops electrolysis by the electrolytic cell control unit 21 (STEP 8), the water passed through the electrolytic cell 6 is discharged through the water discharge pipe 11 as it is. On the other hand, since the solenoid valve 12 (for acidic water) is closed, the water in the water conduit 10 is not released to the outside.
[0010]
When the user closes the faucet 2 and stops water flow, the flow rate sensor 23 determines that the flow rate sensor 23 is not passing water based on the signal from the running water sensor 5 (STEP 3), and then the conditions for cleaning the electrolytic cell 6 are determined. It is determined whether there is a filling cleaning request (STEP 9). When there is no cleaning request, the solenoid valve 12 (for acidic water) is closed (STEP 7), and the electrolysis in the electrolytic cell 6 is stopped (STEP 8).
[0011]
When there is a cleaning request in STEP 9, the electromagnetic valve 12 (for acidic water) is closed (STEP 10), and the electrolytic cell 6 starts electrolysis for cleaning by the electrolytic cell control unit 21 (STEP 11). The electrolysis time for cleaning is managed by the timer 23. Electrolysis for cleaning is to reverse the polarity of the electrode plates 8 and 9 and apply a voltage, thereby separating the scales of calcium, magnesium, etc. attached to the electrode plates 8 and 9 from the electrode plates, Discharge at the next water discharge.
[0012]
[Problems to be solved by the invention]
Such a conventional built-in alkaline water conditioner is used after the user has closed the faucet 2 (including during washing), and water remains in the water discharge pipe. It was uncomfortable for the person.
[0013]
Therefore, an object of the present invention is to provide a built-in alkaline water conditioner in which water from the outlet of the water discharge pipe after the user closes the faucet does not drip.
[0014]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the built-in alkaline water conditioner of the present invention includes a control unit for a valve device that drains water from an electrolytic cell for a certain time when it is detected that water has been stopped by a flow sensor. And
[0015]
According to this invention, it is possible to prevent water from dripping from the outlet of the water discharge pipe after the user closes the faucet and stops water.
[0016]

[0019]
In FIG. 1, 1 is a raw water pipe such as tap water, 2 is a faucet, 3 is a built-in alkaline water conditioner body, 4 is a water purifier, 5 is a flow sensor, 6 is an electrolytic cell, 7 is a diaphragm, and 8 and 9 are Electrode plate, 10 is a water flow pipe, 11 is a water discharge pipe, 12 is a solenoid valve (for acid water) that is a valve device , 13 is an acid water discharge pipe ( drainage pipe ), 14 is a power-on plug, 15 is a power supply unit, Reference numeral 24 denotes control means, and 17 denotes an operation display unit. The electromagnetic valve 12 is provided in a flow path formed from the water discharge pipe 11 to the acidic water discharge pipe 13 through the electrolytic cell 6 and the water flow pipe 10. Here, the water level A shown in the figure indicates a water level at which water does not drip from the water discharge pipe 13 when the user stops the water with the faucet 2.
[0020]

This is a timer in the MPU 25 that manages the control time of the unit 22. Reference numeral 26 denotes electromagnetic valve control means for issuing a command to the electromagnetic valve control unit 22 and draining it for a predetermined time when water stoppage is detected by the flow rate detection unit 19 based on a signal from the flow sensor 5.
[0021]
Next, the operation of the built-in alkaline water conditioner will be described based on the schematic control flow of FIG. 1, FIG. 2 and FIG.
[0022]
When the user sets the alkaline water generation mode by the operation display unit 17 (STEP 1), the setting contents of the user and the current operation state of the built-in alkaline water conditioner are displayed on the operation display unit 17 (STEP 2). Next, when the user opens the faucet 2, the raw water passed through the faucet 2 is freed of impurities such as residual chlorine odor and general bacteria in the raw water by the water purification unit 4, and passes through the flow sensor 5. The water flow is detected by the flow rate detector 19. Here, it is sorted with and without water flow detection (STEP 3). When there is a water flow detection, a drainage request for drainage at the time of water stoppage is issued (STEP 12), and control contents are distributed according to the generation mode set by the user (STEP 4).

When the user closes the faucet 2 and stops the raw water flow, it is determined that the flow rate detection unit 19 is not passing water based on the signal from the running water sensor 5 (STEP 3). When there is a drainage request at the time of water stoppage in STEP 13, the solenoid valve (for acidic water) 12 is opened for a certain time (3 to 5 seconds in this embodiment) by the solenoid valve control means 26 (STEP 14), and shown in FIG. As described above, the residual water in the water discharge pipe 11 passes through the water flow pipe 10, the electromagnetic valve (for acidic water) 12, and the acid water discharge water pipe 13 (drainage pipe), and the acidic water discharge is arranged at a position lower than the water discharge pipe 11 by gravity. The water is drained to the water level A of the water pipe 13 (drain pipe).
[0024]
Next, when the water level of the water discharge pipe 11 falls to the water level A, the drainage request is canceled (STEP 15), and the solenoid valve (for acidic water) 12 is closed (STEP 7). As a result, water does not drip from the water discharge pipe 11 and can be used comfortably. Note that the explanation of the operation of STEP4 to STEP11 is omitted because it is the same as the conventional example.
[0025]
