Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows the configuration of the electrolyzed water generator 1 of the present embodiment. The electrolyzed water generator 1 includes an electrolytic cell 2 for electrolyzing water and a lid 3 attached to the electrolytic cell 2. The electrolyzed water generating device 1 is a batch type electrolyzed water generating device that replaces the water in the electrolytic tank 2 every time the electrolyzed water is generated.

The electrolytic cell 2 has an electrolytic cell 21 and an opening 22 for replenishing the electrolytic cell 21 with water or taking out the electrolyzed water from the electrolytic cell 21. The opening 22 is formed at the upper end of the electrolytic cell 2.

In the electrolytic chamber 21, a first electrode pair 23 for generating electrolyzed water by electrolysis is arranged. When the electrolytic chamber 21 is filled with water and an electrolytic voltage is applied to the first electrode pair 23, an electrolytic current flows between the electrodes to generate electrolytic water. In this embodiment, the electrolytic chamber 21 is provided with a cover member 9 that covers the first electrode pair 23.

The lid 3 is attached to the upper end portion of the electrolytic cell 2 so as to close the opening 22 of the electrolytic cell 2. By attaching the lid 3, access to the electrolytic chamber 21 is restricted.

FIG. 2 shows the electrical configuration of the electrolyzed water generator 1. The electrolyzed water generation device 1 includes a lid detection unit 4 for detecting the mounting state of the lid 3 on the electrolytic cell 2, a water level detection unit 5 for detecting the water level in the electrolytic cell 2, a counting unit 6 for counting time, and the counting unit 6. It includes a control unit 7 that controls each part of the electrolyzed water generation device 1.

FIG. 3 shows a lid detection unit 4, a water level detection unit 5, and the like of the electrolyzed water generator 1. The lid detection unit 4 outputs a signal according to the mounting state of the lid 3 to the control unit 7. The lid detection unit 4 of the present embodiment includes a magnet 41 provided on the lid 3 and a magnetic sensor 42 that detects the magnetic flux density in the vicinity of the lid 3.

The magnet 41 is embedded inside the lid 3, for example. The magnetic sensor 42 is provided at a position facing the magnet 41 when the lid 3 is mounted on the electrolytic cell 2, and outputs a signal corresponding to the magnetic flux density to the control unit 7. Since the magnetic flux density detected by the magnetic sensor 42 depends on the distance between the magnet 41 and the magnetic sensor 42, the control unit 7 determines the mounting state of the lid 3 based on the signal input from the lid detection unit 4. do.

The water level detecting unit 5 includes a second electrode pair 51 for detecting the water level in the electrolytic cell 2. When detecting the water level, a voltage for detecting the water level is applied to the second electrode pair 51. The voltage applied to the second electrode pair 51 is smaller than the electrolytic voltage applied to the first electrode pair 23, and is not intended for electrolysis in the electrolytic cell 2.

When the water level in the electrolytic cell 2 is higher than that of the second electrode pair 51, since the second electrode pair 51 is submerged in water, a current flows through the second electrode pair 51 to which the voltage is applied. The water level detection unit 5 has a current detection unit 52 that detects a current flowing through the second electrode pair 51. The control unit 7 detects the water level in the electrolytic cell 2 based on the signal input from the current detection unit 52.

In this embodiment, the magnetic sensor 42 and the current detection unit 52 are arranged inside the sensor cover 55. The second electrode pair 51 is arranged outside the sensor cover 55 at a position communicating with the electrolytic chamber 21 or the electrolytic chamber 21.

The second electrode pair 51 is arranged above the first electrode pair 23. As a result, the water level detecting unit 5 detects a water level higher than that of the first electrode pair 23. The second electrode pair 51 of the present embodiment is arranged at the height of the reference water level described later.

The form of the lid detection unit 4 and the water level detection unit 5 is not limited to those described above, and can be appropriately deformed.

The counting unit 6 generates a clock signal, and the control unit 7 is housed inside a bottom case 8 arranged below the electrolytic cell 2. The counting unit 6 generates a clock signal and outputs it to the control unit 7.

The control unit 7 has, for example, a CPU 71 (Central Processing Unit) that executes various arithmetic processes, information processing, and the like, a program that controls the operation of the CPU, and a memory 72 that stores various information. The CPU 71 and the memory 72 are mounted on the board 73.

The control unit 7 controls electrolysis in the electrolytic cell based on the signals input from the lid detection unit 4, the water level detection unit 5, and the counting unit 6. More specifically, the control unit 7 counts the time of electrolysis in the electrolytic cell 2 and the time when the lid 3 is removed during the electrolysis, and controls the electrolysis in the electrolytic cell 2. That is, the control unit 7 functions as an electrolytic control unit.

FIG. 4 shows an electrolysis control method 100 of the electrolyzed water generator 1. The electrolysis control method 100 includes a first step S1 to a sixth step S6.

In the first step S1, the lid detection unit 4 detects the mounting state of the lid 3 on the electrolytic cell 2 and outputs a signal corresponding to the mounting state of the lid 3 to the control unit 7. The control unit 7 determines, for example, the wearing state of the lid 3 by comparing the signal input from the lid detection unit 4 with a predetermined threshold value. When it is confirmed that the lid 3 is attached in the first step S1 (Y in S1), the process proceeds to the second step S2.

In the second step S2, the water level detecting unit 5 detects the water level in the electrolytic cell 2 and outputs a signal corresponding to the water level to the control unit 7. The control unit 7 determines, for example, whether or not the water level in the electrolytic cell 2 exceeds the reference water level based on the signal input from the water level detection unit 5. When it is confirmed in the second step S2 that the water level in the electrolytic cell 2 exceeds the reference water level (Y in S2), the process proceeds to the third step S3.

In the third step S3, when the lid 3 is attached to the electrolytic cell 2 (Y in S1) and the water level is higher than the predetermined reference water level (Y in S2), the control unit 7 sets the first electrode pair. An electrolysis current is supplied to 23, and electrolysis is started in the electrolytic cell 2.

The water level detected in the second step S2 is the initial water level in the electrolytic cell 2 before starting electrolysis. However, the water level in the electrolytic cell 2 immediately after the start of electrolysis may be detected. In this case, when it is confirmed that the lid 3 is attached to the electrolytic cell 2 (Y in S1), the process proceeds to the third step S3, electrolysis is started in the electrolytic cell 2, and after a lapse of a predetermined time, the second step is performed. Returning to step S2, the water level in the electrolytic cell 2 is detected. When the detected water level is higher than the reference water level, electrolysis is continued, and when the detected water level is lower than the reference water level, electrolysis is stopped.

In the fourth step S4, the control unit 7 starts measuring the time during which the electrolytic current is being supplied, that is, the time for electrolysis, based on the clock signal input from the counting unit 6.

In the fifth step S5, the lid detection unit 4 detects the state in which the lid 3 is attached to the electrolytic cell 2 during electrolysis. The fifth step S5 is executed in the same manner as the first step S1.

In step S5.1, the electrolysis time is compared with a predetermined time T1.

In the sixth step S6, when the lid 3 is removed from the electrolytic cell 2 (N in S5), or when the electrolysis time elapses for a predetermined time T1 or more (Y in S5.1), the control unit 7 However, the electrolysis current to the first electrode pair 23 is cut off, and the electrolysis in the electrolytic cell 2 is stopped. When the lid 3 is continuously attached to the electrolytic cell 2 (Y in S5), the electrolysis is continued until the electrolysis time is T1 or more (N in S5.1).

After the start of electrolysis in the third step S3, the progress of electrolysis depends on the integration of the electrolysis current and the time of electrolysis. When the control unit 7 controls the electrolysis voltage so that the electrolysis current becomes a constant value, the progress of electrolysis can be estimated from the time of electrolysis, and the time T1 at which sufficient electrolysis can be obtained can be determined. For example, when hypochlorite water is produced by electrolysis, the time T1 for producing hypochlorite water having a chlorine concentration effective against a virus can be set.

The amount of water consumed by electrolysis in the electrolytic cell 2 is very small. Therefore, when it is confirmed in the second step S2 that the water level in the electrolytic cell 2 exceeds the reference water level, the water level in the electrolytic cell 2 does not fall below the upper end of the first electrode pair 23 due to the electrolysis over the time T1. As described above, the reference water level is set.

In the electrolysis control method 100 of the electrolyzed water generator 1 of the present invention, when the lid 3 is attached to the electrolytic cell 2 and the water level is higher than a predetermined reference water level, electrolysis is started in the electrolytic cell 2. Then, when the electrolysis time elapses for a predetermined time T1 or more, or when the lid 3 is removed from the electrolytic cell 2, the electrolysis is stopped. Therefore, immediately after the start of electrolysis, the detection of the water level and the interruption of electrolysis do not occur, so that the operating efficiency (ratio of the electrolysis time to the operating time) can be easily increased while saving the power of the electrolyzed water generator 1. , It becomes possible to generate electrolyzed water in a short time.

Further, when the lid 3 is removed from the electrolytic cell 2 during electrolysis (N in S5), the control unit 7 stops the electrolysis in the electrolytic cell 2 (S6), so that the safety of the electrolyzed water generator 1 is enhanced. Be done.

In the electrolysis control method 100A, in S51, when the time during which the lid 3 is removed during electrolysis is continuously a predetermined time T2 or more (Y in step S5.2), the process proceeds to the sixth step S6 for electrolysis. To stop. On the other hand, when the time when the lid 3 is removed is less than the time T2 (N in step S5.2, Y in S5), the process proceeds to step S5.1. According to the electrolysis control method 100A, the influence of opening the lid 3 in a short time on the operation of electrolysis can be suppressed.

FIG. 6 shows an electrolysis control method 100B, which is another modification of the electrolysis control method 100 of FIG. The configuration of the above-mentioned electrolysis control method 100 or 100A may be adopted for the portion of the electrolysis control method 100B not described below.

In the electrolysis control method 100B, when the lid 3 is removed from the electrolytic cell 2 during electrolysis (N in S5), electrolysis is stopped in step S5.3, and then the lid 3 is attached (in step S5.4). Y), 7th step S7 for resuming electrolysis is included. According to the electrolysis control method 100B, even if the lid 3 is temporarily removed during electrolysis, when the lid 3 is attached thereafter, the electrolysis is automatically restarted, and the electrolyzed water generator 1 is easy to use. Is enhanced.

In the electrolysis control method 100C, the control unit 7 starts the measurement of the electrolysis time after starting the electrolysis in the third step S3 (S4), and counts the primary electrolysis time T3 until the electrolysis is stopped in the step S5.3. do. The primary electrolysis time T3 is the time from the start of electrolysis in the third step S3 to the stop of the electrolysis in step S5.3. When steps S5.3 to 5.5 and the seventh step S7 loop a plurality of times, it is the total time.

Then, in the electrolysis control method 100C, a new time T1 is calculated by subtracting the primary electrolysis time T3 from the original time T1 (step S5.5), and electrolysis is restarted (7th step S7). In the electrolysis control method 100C, since the electrolysis is restarted in consideration of the primary electrolysis time T3 from the start of the electrolysis to the removal of the lid 3 from the electrolytic cell 2, the opening of the lid 3 affects the electrolysis time. The effect can be suppressed.
