In this way, the electronic control module 80 adjusts and outputs the preset voltage applied to the electronic anode 30 according to the measured level of the potential value in the liner 10, so as to stabilize the potential value of the liner 10 at the corrosion stopping level, thereby protecting the liner 10 from corrosion, and simultaneously preventing the electronic anode 30 from being applied with an improper preset voltage, and further improving the service lives of the electronic anode 30 and the liner 10.

Specifically, in one embodiment (as shown in fig. 4), the water heater 100 may be a standing dual-liner water heater 100, and when the standing dual-liner water heater 100 is used, two liners 10 are vertically installed side by side, and the bottoms may be communicated by a connecting pipe 12. One end of the inner container 10 may be provided with an electron anode 30 and a magnesium rod 20, and one end of the other inner container 10 may be provided with an electron anode 30 and a magnesium rod 20. The inner container 10, the electron anode 30 and the magnesium rod 20 can be electrically connected with the electronic control module 80 through a connecting wire 81.

In another embodiment (as shown in fig. 5), the water heater 100 may be a horizontal dual-liner electric water heater 100, and when the horizontal dual-liner water heater 100 is used, the upper and lower liners 10 are horizontally installed side by side, and the middle is communicated by two connecting pipes 12. One end of the inner container 10 can be provided with an electron anode 30 and a magnesium rod 20, and the other inner container 10 can be provided with the electron anode 30 at one end and the magnesium rod 20 at the lower part. The inner container 10, the electron anode 30 and the magnesium rod 20 can be electrically connected with the electronic control module 80 through a connecting wire 81.

After the two inner containers 10 are filled with water, a voltage can be input to the electronic control module 80, the value of the input voltage can be 3V to 10V, the electronic control module 80 can be started, the electronic control module 80 can communicate the inner containers 10 with the electronic anode 30 through the control relay, the inner containers 10 are communicated with the electronic anode 30 and output a preset voltage, the value of the output preset voltage can be 0.2V to 8V, the groove pressure is applied to the electronic anode 30 and the inner containers 10, cathode polarization current is respectively provided for the two inner containers 10, the electronic control module 80 adjusts the output voltage to the electronic anode 30 according to the measured potential value, and the potential values of the two inner containers 10 are respectively stabilized at the corrosion stopping level.

The potential value is inversely related to the predetermined voltage. It will be appreciated that, for example, when the electric potential value of the inner container 10 measured by the electric control module 80 is at 900mV, the electric control module 80 may measure that the electric potential value of the inner container 10 is at a stable corrosion stop level, when the electric potential value of the inner container 10 measured by the electric control module 80 is less than 900mV, the electric control module 80 may adjust the predetermined voltage input to the electronic anode 30, for example, the voltage may be increased from 500mV to 1000mV, thereby the electronic anode 30 may increase the electric potential value of the inner container 10 to 900mV, and the inner container 10 may be at a stable corrosion stop level. Similarly, when the electric potential value of the inner container 10 measured by the electric control module 80 is greater than 900mV, the inner container 10 may be corroded, the electric control module 80 may adjust the predetermined voltage input to the electronic anode 30, for example, the voltage may be reduced from 1000mV to 500mV, thereby the electronic anode 30 may reduce the electric potential value of the inner container 10 to 900mV, and the inner container 10 may be at a stable corrosion stopping level.

Referring to fig. 3-5, in some embodiments, the electronic control module 80 is further configured to control the switch 90 to switch the position to disconnect the electronic anode 30 from the inner container 10 and electrically connect the magnesium rod 20 to the corresponding inner container 10 when the potential value is abnormal; and/or the number of the groups of groups,

Stopping applying a voltage to electron anode 30; and/or the number of the groups of groups,

and sends out a corresponding alarm signal of the liner 10.

In this way, the electric control module 80 detects abnormal potential value of the water heater 100, so that the control switch 90 can disconnect the electric connection between the electronic anode 30 and the liner 10 under the conditions of power failure of the electric water heater 100, failure of the electronic anode 30 and the like, and the magnesium rod 20 is adopted to perform corrosion protection on the liner 10 and send out an alarm signal, thereby achieving the purposes of reducing the loss of the magnesium rod 20, prolonging the service life of the liner 10 and reducing water pollution. The electronic control module 80 can also send out an alarm signal to improve the safety of the water heater 100 in the use process.

Specifically, when the electronic control module 80 detects that the potential value of one of the inner containers 10 is in a fault state, the electronic anode 30 in the inner container 10 can immediately stop outputting the predetermined voltage, then the fault of the inner container 10 and the electronic anode 30 assembly can be processed, the connection between the electronic anode 30 and the inner container 10 can be disconnected, the magnesium rod 20 and the inner container 10 are connected, the magnesium rod 20 is adopted to perform corrosion protection on the inner container 10, and meanwhile, the electronic control module 80 can also synchronously and independently send out an alarm signal. It is understood that the other liner 10 and the electron anode 30 in the other liner 10 are not affected, and the electron anode 30 continuously protects the other liner 10.

If the electric control module 80 is powered off or detects that the electric potentials of the two inner containers 10 are in a fault state, the connection between the two electronic anodes 30 and the two inner containers 10 is disconnected, and the two inner containers 10 are respectively connected with the corresponding magnesium rods 20, so that the two inner containers 10 are continuously protected.

For example, when the electric potential value of the inner container 10 exceeds 1200mV and is in a fault state, the electric control module 80 detects that the electric potential value of the inner container 10 exceeds 1200mV, the electric control device can output a predetermined voltage to the electronic anode 30 in the inner container 10 to be zero and send out an alarm signal, and the electric control device can also control the switch 90 to disconnect the electronic anode 30 from the inner container 10.

Referring to fig. 3-5, in some embodiments, the electronic control module 80 is configured to detect the potential value in the liner 10 once every predetermined period of time, and reduce the period of time for applying the voltage to the electron anode 30 if the potential value is greater than the threshold value; in the case where the potential value is smaller than the threshold value, the period of time for which the voltage is applied to the electron anode 30 is increased, and the period of time for which the voltage is applied to the electron anode 30 is equal to the predetermined period of time.

In this way, the electronic control module 80 further adjusts the duration of the voltage applied to the electronic anode 30 according to the magnitude of the voltage value detected by the inner container 10 from time to time, so as to stabilize the voltage value of the inner container 10 at the corrosion stopping level, thereby protecting the inner container 10 from corrosion, and preventing the duration of the abnormal voltage applied to the electronic anode 30 from affecting the service lives of the electronic anode 30 and the inner container 10.

Specifically, after both the inner containers 10 are filled with water, the electric control module 80 may detect the electric potential value of the inner container 10 for a predetermined period of time, for example, the threshold value of the electric potential value may be 900mV, and the electric control module 80 may keep the electric potential value of the inner container 10 stable at the threshold value when the electric anode 30 is applied with a voltage fixed at 1000mV for 5 minutes. When the electric control module 80 detects that the electric potential value of the inner container 10 is 1200mV in 5 minutes, the electric potential value of the inner container 10 is greater than the threshold value, the electric control module 80 can keep a fixed voltage of 1000mV and apply a voltage to the electron anode 30 for a period of time of less than 5 minutes, and the electric potential value of the inner container 10 can be reduced to a threshold state of 900 mV. Similarly, when the electric control module 80 detects that the electric potential value of the inner container 10 is 700mV within 5 minutes, the electric control module 80 can maintain a fixed voltage of 1000mV and apply a voltage to the electron anode 30 for a period of time greater than 5 minutes, so that the electric potential value of the inner container 10 can be raised to a threshold state of 900 mV.

Referring to fig. 6, in a control method of a water heater 100 according to an embodiment of the present application, the water heater 100 includes a plurality of inner containers 10 and a plurality of electronic anodes 30, the plurality of inner containers 10 are mutually communicated, each inner container 10 is provided with at least one electronic anode 30, and the control method includes:

S1: in the case where the electron anode 30 is electrically connected to the corresponding inner container 10, detecting a potential value in the inner container 10 by the electron anode 30;

s2: a predetermined voltage is applied to electron anode 30 according to a potential value that is inversely related to the predetermined voltage.

The control method of the water heater 100 according to the embodiment of the application can adjust and output the preset voltage applied to the electronic anode 30 according to the measured level of the potential value in the liner 10, so as to realize the stabilization of the potential value of the liner 10 at the corrosion stopping level, thereby protecting the liner 10 from corrosion, and simultaneously preventing the application of improper preset voltage to the electronic anode 30, thereby affecting the service lives of the electronic anode 30 and the liner 10.

Specifically, the electronic anode 30 is electrically connected with the inner container 10, then the electronic anode 30 detects the potential value of the inner container 10, and then the electronic anode 30 judges the potential value relative to the set value, and further adjusts the preset voltage applied to the electronic anode 30, when the potential value is higher than the preset value, the preset voltage is reduced, when the potential value is lower than the preset value, the preset voltage is increased, and the potential value is inversely related to the preset voltage.

Referring to fig. 7, in some embodiments, the control method further includes:

S3: in the case of abnormal potential value, the control switch 90 switches the position to disconnect the electronic anode 30 from the inner container 10 and electrically connect the magnesium rod 20 to the corresponding inner container 10; and/or the number of the groups of groups,

s4: stopping applying a voltage to electron anode 30; and/or the number of the groups of groups,

s5: and sends out a corresponding alarm signal of the liner 10.

In this way, the electric control module 80 detects abnormal potential value of the water heater 100, so that the control switch 90 can disconnect the electric connection between the electronic anode 30 and the liner 10 under the conditions of power failure of the electric water heater 100, failure of the electronic anode 30 and the like, and the magnesium rod 20 is adopted to perform corrosion protection on the liner 10 and send out an alarm signal, thereby achieving the purposes of reducing the loss of the magnesium rod 20, prolonging the service life of the liner 10 and reducing water pollution. The electronic control module 80 can also send out an alarm signal to improve the safety of the water heater 100 in the use process.

Specifically, after the electric potential value of the inner container 10 is detected through the electron anode 30 in the steps (S1 and S2), it may be further judged whether the electric potential value is in an abnormal state, and then the electric connection of the electron anode 30 and the inner container 10 may be simultaneously disconnected and switched to the connection of the magnesium rod 20 and the corresponding inner container 10 by controlling the position of the switching switch 90, and then the application of the predetermined voltage to the electron anode 30 may be stopped, and then an alarm signal may be issued to the corresponding inner container 10.

Further, it can be understood that, after the electronic control module detects and determines that the potential value is in the abnormal state, one, two or all of steps S3, S4 and S5 may be performed. For example, when the electric control module 80 detects that the electric potential value of the inner container 10 is 2500mV, one of the steps S3, S4 and S5 may be performed, i.e., the electric control module 80 may control the control switch 90 to disconnect the electric connection between the electronic anode 30 and the inner container 10 and switch the magnesium rod 20 to connect with the corresponding inner container 10 or stop applying the predetermined voltage to the electronic anode 30 or send an alarm signal to the corresponding inner container 10.

Similarly, two of steps S3, S4 and S5 may be performed, that is, the electronic control module 80 may control the control switch 90 to disconnect the electronic anode 30 from the inner container 10 and switch to connect the magnesium rod 20 to the corresponding inner container 10 while stopping applying the predetermined voltage to the electronic anode 30; alternatively, the electronic control module 80 may control the control switch 90 to disconnect the electronic anode 30 from the inner container 10 and switch to connect the magnesium rod 20 to the corresponding inner container 10 and send an alarm signal to the corresponding inner container 10; alternatively, the electronic control module 80 stops applying a predetermined voltage to the electron anode 30 while emitting an alarm signal to the corresponding inner container 10.

Similarly, all steps of steps S3, S4 and S5 may be performed, that is, the electronic control module 80 may control the control switch 90 to disconnect the electronic anode 30 from the inner container 10 and switch to connect the magnesium rod 20 to the corresponding inner container 10 and stop applying the predetermined voltage to the electronic anode 30 and issue an alarm signal to the corresponding inner container 10.

Referring to fig. 8, in some embodiments, the control method further includes:

s6: detecting the potential value in the liner 10 once every a preset time;

s7: in the case where the potential value is greater than the threshold value, the duration of decreasing the voltage applied to the electron anode 30 is equal to the predetermined duration; in the case where the potential value is smaller than the threshold value, the period of time for which the voltage is applied to the electron anode 30 is increased, and the period of time for which the voltage is applied to the electron anode 30 is equal to the predetermined period of time.

In this way, the electronic anode 30 is used as a reference electrode, the real-time potential of the liner 10 is measured at intervals of a predetermined time, after the measured value of the potential of the liner 10 is compared with the threshold value, the time of the voltage applied to the electronic anode 30 is immediately adjusted, the potential of the liner 10 is at the corrosion stopping level, and the potential of the liner 10 can be dynamically adjusted and maintained within the protective potential range all the time by continuously cycling the above steps. If a fault occurs, the device can be identified and then enters a fault mode, and the internal but protection is performed by adopting a standby device through fault treatment, so that the inner containers 10 can be protected under various conditions, the working processes of the plurality of electronic anodes 30 are mutually independent and do not interfere with each other, and the plurality of inner containers 10 can be protected simultaneously.

Specifically, the potential value in the inner container 10 may be detected once for a certain predetermined period of time, and then the period of time for applying the voltage to the electron anode 30 may be reduced in the case where the potential value is greater than the threshold value, and simultaneously, the period of time for applying the voltage to the electron anode 30 may be increased in the case where the potential value is less than the threshold value, and at this time, the period of time for applying the voltage to the electron anode 30 is equal to the predetermined period of time.

In a certain embodiment (as shown in fig. 9 and referring to fig. 3-5), in the case that the electronic anode 30 is electrically connected to the corresponding inner container 10, the electronic anode 30 operates in a start-up mode, and the electric control device 80 performs power-on and power-off for a predetermined period of time to the inner container 10 and the electronic anode 30 and detects the potential value in the inner container 10, and detects the potential value Ut at the time Tj after the detection period Tj for the predetermined period of time is operated. Judging whether the Ut is in a fault state at this time, if the Ut is in a fault state, performing fault handling directly, wherein the fault handling can adopt one or more of the execution modes of step S3, step S4 and step S5, for example, the control switch 90 can disconnect the electrical connection between the electronic anode 30 and the liner 10, can adopt the magnesium rod 20 to perform corrosion protection on the liner 10, and can send out fault handling modes such as an alarm signal. Then, a standby device can be used for protecting the liner 10, and the standby device can be a standby magnesium rod or an electronic anode for replacing a fault device and other disposal modes; if normal, enter the adjustment mode.

In the adjustment mode, the operation is performed by adopting the on-off time with the preset time, after one Tj is performed, the potential value U1 of the liner 10 is detected, whether the Ut is in a fault state is detected, if the Ut is in the fault state, fault treatment is performed, and the liner 10 is protected by adopting a standby device; if normal, comparing U1 with a threshold U0, and if U1 is greater than U0, reducing the duration of voltage application to the electron anode 30; if U1 is smaller than U0, the duration of voltage application to electron anode 30 is increased. And starting to execute the switching on and switching off of a new preset time length in the next period. After one Tj is operated, the potential value U1 of the liner 10 is detected again, and fault judgment, identification and energization time length adjustment are performed. In this way, the protection of the liner 10 is achieved.

The other electron anode 30 is operated simultaneously by the same control method as the electron anode 30 described above, and independently protects the other liner 10.

In another embodiment (as shown in fig. 10 and referring to fig. 3 to 5), in the case where the electron anode 30 is electrically connected to the corresponding inner container 10, the power on/off for a predetermined period of time may be performed to the inner container 10 and the electron anode 30 by the electronic control device 80 and the potential value in the inner container 10 may be detected. The electronic anode 30 operates in a start-up mode a, which may be a predetermined duration of on-off performed by the electronic control module that is shorter than the predetermined duration of the start-up mode in the embodiment of fig. 9. After running for a predetermined period of time TA, the operation is changed to a running start mode B, where the start mode B may be a predetermined period of time on-off performed by the electronic control module compared with the start mode in the embodiment of fig. 9. The adjustment mode is entered after a further predetermined period TB. The fault judgment, identification and processing are not performed in the stage between the operation starting mode A and the operation starting mode B.

In the adjustment mode, the on-off time with the preset time length is adopted to run, after a potential value detection period Tj is run, the potential value U1 of the liner 10 is detected, whether the Ut is in a fault state is detected, if the Ut is in a fault state, fault treatment is performed, one or more execution modes in the steps S3, S4 and S5 can be adopted for fault treatment, for example, the control switch 90 can disconnect the electronic anode 30 from the liner 10, the magnesium rod 20 can be adopted to carry out corrosion protection on the liner 10, and fault treatment modes such as an alarm signal can be sent out. The liner 10 is protected by a standby device, and the standby device can be a standby magnesium rod or an electronic anode for replacing a fault device and other disposal modes; if normal, comparing U1 with a threshold U0, and if U1 is greater than U0, reducing the duration of applying voltage to the electron anode 30; if U1 is smaller than U0, the duration of applying the voltage to electron anode 30 is increased. A new power-on/off for a predetermined period of time is started at the next cycle. After one Tj is operated, the potential value U1 of the liner 10 is detected again, and fault judgment, identification and adjustment of the energization time period are performed. In this way, the protection of the liner 10 is achieved.

The other electron anode 30 is operated simultaneously by the same control method as the electron anode 30 described above, and independently protects the other liner 10.
