Description of the Related Art As one type of electrolyzed water producing apparatus, a stoppered electrolyzed water producing apparatus, that is, a faucet provided at the tip of a spout pipe is opened so that water to be treated from an external water supply source is electrolyzed. The electrolyzed water generation device is configured so that the water to be treated is electrolyzed in the electrolytic cell to generate electrolyzed water, and the generated electrolyzed water is discharged from the open faucet. It has been known. In such a type of electrolyzed water generator, water pressure is constantly acting on the water channel system leading to the faucet, and there is a risk of water leakage from the pipe connection portion, the electrolytic cell, or the like,
Alternatively, there is a risk of water leakage due to rupture of a waterway system due to freezing in winter, and in case of water leakage, it is necessary to know the water leakage immediately.

An electrolyzed water producing apparatus that copes with the problem is disclosed in Japanese Patent Laid-Open No. 11-314090. This electrolyzed water generator detects water leakage by using each flowing water sensor (electrolyzed water generation flow rate sensor) provided for controlling energization of the electrodes. In this case, since the electrolyzed water generation flow rate sensor detects a flow rate that is equal to or higher than a predetermined value that is smaller than the electrolysis start flow rate for starting energization control, the electrolyzed water generation device detects water leakage that is a flow rate that is equal to or higher than the predetermined value. You can do it. On the other hand, since the electrolyzed water generation flow rate sensor does not detect a flow rate less than the predetermined value smaller than the electrolysis start flow rate, there is a problem that the electrolyzed water generation device cannot detect the leakage of water having the flow rate less than the predetermined value. It was

Therefore, an object of the present invention is to allow a user to accurately grasp the occurrence of water leakage by allowing the pre-stop type electrolyzed water generator to reliably detect a smaller amount of water leakage and notify that the water is leaking. Is.

And so on. The control device 100 has a microcomputer (not shown) and controls the opening and closing of the drainage valves 71 and 72, the application to the electrodes 14 and 15, and the operation control of the display 103 and the alarm buzzer 104.

The microcomputer includes a CPU and an R which are respectively connected to the input / output interface via a bus.

Next, generation of electrolyzed water and detection of leaked water by the electrolyzed water producing apparatus configured as described above will be described. In this electrolyzed water generator, there are cases where both alkaline water and acidic water are separately poured out, and where either one of alkaline water and acidic water is poured out, both cases will be described below. The generation control of the electrolyzed water in the above-mentioned stop-type electrolyzed water generating apparatus is well known, and the well-known control is also performed in the present electrolyzed water generating apparatus, and thus detailed description thereof will be omitted.

1. When pouring out both the generated alkaline water and acidic water, each faucet 43 to 46 is completely closed (closed state),
In the electrolyzed water generator in a state where the main switch 101 is not turned on (off state), the main switch 1
When 01 is turned on and turned on, the microcomputer of the control device 100 executes the program shown in FIG. 2 every predetermined short time.

First, the control unit 100 inputs the detection signals from the electrolyzed water producing flow rate sensors 81 and 82, and calculates the flow rate based on the detection signals (steps 110 and 12).
0). Next, the control device 100 uses the electrolytic generation switch 105.
Is pressed to turn it on, and each faucet 43, 4
When 4, 45 and 46 are manually opened by the user and the flow rates of the supply pipes 21 and 22 become equal to or higher than the electrolysis start flow rate, generation of electrolyzed water is started (steps 130 to 150). That is, the control device 100 includes the pair of electrodes 1 in the electrolytic cell 10.
The application of a voltage in a predetermined direction is started between Nos. 4 and 15, and both drain valves 71 and 72 are maintained in a closed state. Therefore, the user manually operates each of the faucets 43, 44, 45, 4
By opening 6, the water to be treated supplied to the electrolyzer 10 is electrolyzed in each of the electrode chambers 12 and 13, and the generated electrolyzed water passes through the flow path switching valve 50 and reaches the predetermined pouring pipe 4 respectively.
Poured from 1,42. For example, alkaline water is poured out from the outlet pipe 41, and acidic water is discharged from the outlet pipe 42.

The control device 100 includes an electrolytic generation switch 10
Each water faucet 43, 4 opened again until 5 is turned off
4, 45, 46 are manually closed by the user and the generation of electrolyzed water is continued until the flow rates of the supply pipes 21, 22 become less than the electrolysis start flow rate (steps 100 to 160).

During the generation of the electrolyzed water, the control device 100 controls the direction of the voltage applied between the electrodes 14 and 15 and the outlet pipes 31 and 32 and the outlet pipes 41 and 32 which are interlocked with the direction.
The communication state of 42 is switched every predetermined time. As a result, the desired electrolyzed water is poured out from the predetermined pouring pipe, while the electrodes 14 and 15 are consumed uniformly, and the scale is prevented from adhering to the electrodes 14 and 15. Further, during this switching, the control device 100 opens the drain valves 71 and 72, and anything other than the desired electrolyzed water is drained to the outside through the drain pipes 61 and 62 rather than after the branch of the spout pipes 41 and 42. It has become so. This allows
During switching, nothing other than the desired electrolyzed water is poured out from the tips of the pouring pipes 41, 42, and the user can obtain the desired electrolyzed water from the pouring pipes 41, 42.

Further, the control device 100 switches the type of electrolyzed water which is poured out from the spouting pipes 41 and 42 every predetermined time longer than the above-mentioned predetermined time. For example, the acidic water may be poured out from the spouting pipe 41 that has been pouring out the alkaline water before switching, or the alkaline water may be poured out from the spouting pipe 42 that was pouring out the acidic water before switching. ing. As a result, both the alkaline water and the acidic water of electrolyzed water are alternately passed through the respective pouring pipes 41 and 42, so that the scale adheres only to one pouring pipe 41 (or the pouring pipe 42). Prevent.

During the production of such electrolyzed water, the water taps 43, 44, 45, 46 in the open state are closed while the electrolysis production switch 105 is maintained in the ON state, and the supply pipes 21, 22 are closed. When each flow rate is less than the electrolysis start flow rate,
The control device 100 stops the production of electrolyzed water (step 1
30, 140, 170). That is, the control device 100 stops the application of the voltage between the pair of electrodes 14 and 15 in the electrolytic cell 10 to stop the generation of electrolyzed water (step 17).
0). The control device 100 includes the faucets 43, 44 in the closed state,
The generation of electrolyzed water is stopped until 45 and 46 are opened and the flow rates of the supply pipes 21 and 22 are equal to or higher than the electrolysis start flow rate.

While the production of the electrolyzed water is stopped, that is, when the electrolysis production switch 105 is in the ON state and the flow rates of the supply pipes 21 and 22 are less than the electrolysis start flow rate, the predetermined value a or more is exceeded. When a leak of water, which is the flow rate, occurs, the control device 100 detects the leak and gives a notification to that effect (steps 100 to 140, 170).
~ 190,160). That is, the control device 100 calculates the flow rate based on the detection signals input from the electrolytic water generation flow rate sensors 81 and 82 (step 120), and determines that there is water leakage when the calculated flow rate is equal to or greater than the predetermined value a. Then (step 180), it is notified that there is water leakage (step 190). Specifically, the display device 103 is used as a notification means.
The alarm buzzer 104 may be used to display on the display 103 that water is leaking.
4 may be sounded in a predetermined state.

Further, when a water leak having a flow rate less than the predetermined value a occurs, the control device 100 detects the water leak and gives a notification to that effect (steps 100 to 140, 170, 18).
0,200,210,190,160). That is, the control device 100 inputs a detection signal from the leak detection flow sensor 83 (step 200), determines that there is a flow rate based on the input detection signal and determines that there is water leakage (step 210), and the water leakage is detected. Notify that there is (step 19)
0).

Then, the control device 100 does not notify that there is water leakage unless water leakage occurs (step 10).
0-140,170,180,200,210,16
0).

When the electrolysis generation switch 105 is pressed to be turned off during the generation of the electrolyzed water described above, the control device 100 stops the production of the electrolyzed water (steps 130, 1).
70). That is, the control device 100 stops the application of the voltage between the pair of electrodes 14 and 15 in the electrolytic cell 10 to stop the generation of electrolyzed water (step 170). In this case, since each of the faucets 43, 44, 45, 46 is not closed and remains in the open state, electrolytic water or water to be treated has been poured out from the pouring pipes 41, 42 and supplied. The flow rate of the water to be treated flowing through the tubes 31 and 32 is equal to or higher than the electrolysis start flow rate, that is, equal to or higher than a predetermined value a. Therefore, the control device 100 determines that the calculated flow rate is greater than or equal to the predetermined value a (step 18
0), and notifies that there is water leakage (step 190). The control device 100 continues this notification state until the faucets 43, 44, 45, 46 are closed and the respective flow rates of the supply pipes 21, 22 become less than the electrolysis start flow rate.

Further, when the electrolytic generation switch 105 is in the OFF state, and if water leakage having a flow rate of a predetermined value a or more occurs, the control device 100 detects the water leakage and gives a notification to that effect (step 100). ~ 140,170 ~
190, 160). That is, the control device 100 calculates the flow rate based on the detection signals input from the electrolytic water generation flow rate sensors 81 and 82 (step 120). Since the calculated flow rate is equal to or greater than the predetermined value a, that is, the flow rate is present, there is water leakage. It is determined (step 180) that there is water leakage (step 190). Further, when the water leakage having the flow rate less than the predetermined value a occurs, the control device 100 detects the water leakage and gives a notification to that effect (steps 100 to 140,
170, 180, 200, 210, 190, 160).
That is, the control device 100 includes the flow rate sensor 8 for detecting water leakage.
The detection signal is input from 3 (step 200), and it is determined that there is water leakage based on the input detection signal (step 2).
10) Notify that there is water leakage (step 190).
If the water leakage does not occur, the control device 100 does not notify the water leakage (steps 100 to 140,
170, 180, 200, 210, 160).

In the above description of the operation, the case where all of the faucets 43, 44, 45 and 46 are opened has been described, but either one of the faucets 43 and 44 and the faucet 4 is described.
The same control as when all of the faucets are opened is performed when either one of the valves 5 and 46 is opened.

2. When the generated alkaline water or acidic water is poured out alone In this case, the point different from the case where both the alkaline water and the acidic water are poured out is the faucet 43, 44 (or the faucet 45, 46) Only the alkaline water or the acidic water is discharged from the spout pipe 41 (or the spout pipe 42) by the user to manually open the spigot 45, 46 (or the closed faucet 45 or 46). Acid water or alkaline water that should be discharged from the spout pipe 42 (or the spout pipe 41) provided with the water faucets 43, 44 is drainage pipe 62 (or drain pipe 61), drain valve 72 (or drain valve). 71) and the drainage pipe 63 to be drained to the outside of the electrolyzed water generator. Specifically, the control device 100 performs step 1
At 40, it is determined that the flow rate of the supply pipe 21 or 22 is equal to or higher than the electrolysis start flow rate, and at step 150, the electrolytic cell 10
The application of a voltage in a predetermined direction is started between the pair of electrodes 14 and 15 inside, and the drain valve 72 is intermittently opened.

During the production of electrolyzed water when the produced alkaline water or acidic water is solely poured out, the same switching control and electrolysis water production stop control as described above are performed. Further, even when the electrolyzed water is stopped in this case, the same water leakage detection / notification control as described above is performed.

In the above description of the operation, the case where all of the faucets 43, 44 or the faucets 45, 46 are opened has been described. However, the faucets 43, 44 or the faucets 45, 4 have been described.
When either one of 6 is opened, the same control as when both faucets are opened is performed.

As can be understood from the above description, in this embodiment, the control device 100 includes the electrodes 14 and 1.
When a water leak that is less than a predetermined value a smaller than the electrolysis start flow rate for starting the application of the voltage between 5 is detected, the leak detection flow sensor 83 detects a flow rate less than the predetermined value a smaller than the electrolysis start flow rate. Then, the control device 100 determines that there is water leakage based on this detection result and notifies that fact (steps 200 and 210). Therefore, in the first-stop type electrolyzed water generator, the user can accurately grasp the occurrence of water leakage by surely detecting a smaller amount of water leakage and notifying that it is water leakage. Further, the flow sensor 83 for detecting water leakage is replaced with the flow sensor 8 for generating electrolytic water.
Since it is provided at the upstream position of 1, 82, the leak water detection flow sensor 83 and the electrolytic water generation flow sensors 81, 82.
Leakage in the waterway system between and can be detected by specifying its location. For example, water leakage from the safety valve 28 can be detected.

In the above embodiment, the leak water detecting flow sensor 83 is provided inside the electrolyzed water producing apparatus, but the leak detecting flow sensor 83 is provided outside the electrolyzed water producing apparatus. Good. In this case, the water leak detection flow sensor 83 may be provided between the main tap 26 and the pressure reducing valve 23, and the detection signal from the water leak detection flow sensor 83 may be input to the control device 100. Further, a leak detector 200 different from the leak detecting flow sensor 83 may be provided between the main plug 26 and the pressure reducing valve 23 outside the electrolyzed water generator. As shown in FIG. 3, the leak detector 200 includes a leak detecting flow sensor 83, a water valve 201, a display 202, a buzzer 203, and a control circuit 2.
04, the control circuit 204 inputs the detection signal from the water leakage detection flow sensor 83 and determines that there is water leakage when the electrolysis stop signal is input from the control apparatus 100 of the electrolyzed water generation apparatus. While 201 is closed, the display 202 and the buzzer 203 notify the user of water leakage. According to this, it is possible to detect water leaks in all of the water channel system inside the electrolyzed water generator and the piping of the water channel system (water channel system outside the electrolyzed water generator) from the electrolyzed water generator to the water pipe (main tap). . In this case, the water valve 201 may be omitted.

Further, in the above embodiment, the electrodes 14, 15 are provided separately from the electrolyzed water producing flow rate sensors 81, 82.
A leak detection flow sensor 83 for detecting a flow rate less than a predetermined value a smaller than the electrolysis start flow rate for starting the control for applying a voltage is provided, and the sensor 83 detects a flow rate less than the predetermined value a smaller than the electrolysis start flow rate. When detected, the control device 1
00 is determined to have water leakage, but as the electrolytic water generation flow rate sensors 81 and 82, a flow rate sensor that also detects a flow rate less than a predetermined value a smaller than the electrolysis start flow rate is adopted.
When the flow rate sensor detects a flow rate smaller than the predetermined value a smaller than the electrolysis start flow rate, the control device 100 may determine that there is water leakage. With this, the same effect as that of the above-described embodiment can be obtained.

Further, in the case where the electrolyzed water is continuously produced in the above-mentioned embodiment, the notifying means normally produces the water until a predetermined time elapses from the time when the electrolysis controlling means starts the energization control of the electrodes. The second state indicating the first state and the failure state in the notification means after a predetermined time has elapsed from the time when the electrolysis control means starts the energization control of the electrodes.
It is preferable to represent a third state different from the state. First, the case where the display 103 is used as the notification means (for example, the case where a 2-digit 7-segment LED is used) will be specifically described. In this case, the control device 100
Displays the first state on the display 103 until a predetermined time elapses from the time when the energization control of the electrodes 14 and 15 is started, and displays the third state on the display 103 after the predetermined time elapses. The first state is to light each segment so as to rotate one by one, the second state is to display a character such as "E3" indicating a failure time, and the third state is to display the first state. The state and the second state are different display states, for example, the character "ch" is displayed.
