Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and in particular to a magnesium rod assembly, a water heater and a magnesium rod consumption monitoring method. Background Art

[0002] In the design and use of air-energy water heaters, the anti-corrosion protection of water tanks is an important technical issue. When the water tank leaves the factory, it is usually equipped with a magnesium rod, which is sacrificed as an anode to protect the water tank and prevent the inner tank from corrosion. The magnesium rod protects the water tank by consuming itself. It is a consumable and needs to be replaced in time after consumption, otherwise the water tank may be corroded. At present, there are usually two ways in the industry to inform users whether the magnesium rod is: one is to tell customers how much time (for example, 3 years) after the water tank is installed to replace the magnesium rod; the second is to use big data analysis to measure the standard tap water quality of each water tank sales location, and then match the database according to the water tank installation location, so that it can be roughly determined how long the magnesium rod in the area is expected to be consumed, and then replace it regularly. Although these two solutions have solved the problem of magnesium rod replacement to a certain extent, they both have common disadvantages. First, these methods may lead to waste of magnesium rods, that is, the magnesium rods have not been consumed but the replacement time has come, or leave the water tank in an unprotected state, that is, the magnesium rods have been consumed but the replacement time has not yet come. Secondly, these two methods cannot obtain real-time monitoring of the remaining amount of magnesium rods, and cannot replace the magnesium rods immediately after they are consumed.

[0003] Therefore, it is necessary to improve the existing method of judging whether the magnesium rod needs to be replaced to overcome the defects of the prior art. Summary of the invention

[0004] In order to overcome the problems existing in the related art, one of the objects of the present invention is to provide a magnesium rod assembly, which can detect the current value passing through the magnesium rod during use, thereby monitoring the remaining amount of the magnesium rod in real time through the current value, so that the user can be reminded to replace it in time when the magnesium rod is exhausted, thereby improving the user's usage experience.

[0005] A magnesium rod assembly, comprising:

[0006] A component body, on which a piezoresistive sensor is disposed;

[0007] When the magnesium rod is used, the varistor sensor is used to detect the current value flowing through the component.

[0008] Specifically, the magnesium rod is used in the water heater, and the varistor sensor is selected to be a model that can accurately respond to tiny weight changes to ensure that it can sensitively capture the weight reduction of the magnesium rod during use. When the magnesium rod is brand new and unused, the varistor sensor outputs a reference current value based on the initial weight of the component. As the magnesium rod is used in the water heater, magnesium ions gradually dissolve in the water, causing the overall weight of the magnesium rod assembly to gradually decrease. The varistor sensor captures this weight change in real time and converts it into a corresponding electrical signal change, that is, the detection current value gradually decreases.

[0009] The water heater’s control system has a built-in algorithm that processes the sensor signal and converts it into an intuitive display of the remaining magnesium rod amount, such as a percentage or an estimated remaining usage time.

[0010] When the remaining amount of magnesium rod is lower than the preset threshold, the control system automatically triggers the reminder function and notifies the user to replace the magnesium rod through the water heater display or connected smart device (such as mobile phone APP). The system automatically monitors the status of the magnesium rod, without the need for manual inspection by the user, which greatly reduces the user's usage burden.

[0011] The automatic monitoring and reminder function of this method eliminates the need for users to manually check the status of the magnesium rod regularly, thus improving the convenience of use and user satisfaction. Timely reminders to replace the magnesium rod avoid performance degradation or damage to the water heater due to magnesium rod exhaustion, thus ensuring the daily needs of users.

[0012] In a preferred technical solution of the present invention, the component body includes a magnesium rod body and a first joint, the magnesium rod body is detachably arranged on one side of the first joint, and the varistor sensor is detachably arranged on the first joint.

[0013] The first joint is used to connect the assembly to the water heater. More preferably, the first joint is designed to be a structure that matches the magnesium rod body to facilitate installation and disassembly of the magnesium rod body.

[0014] In a preferred technical solution of the present invention, a sealing gasket is provided on the first joint, and the sealing gasket is arranged on a side of the first joint close to the magnesium rod body.

[0015] The sealing gasket is used to enhance the sealing performance of the first joint during installation to prevent moisture from leaking from the first joint.

[0016] In a preferred technical solution of the present invention, the magnesium rod body includes a rod body and a second joint, the second joint is arranged at one end of the rod body, and the second joint is fixedly connected to the rod body through a mandrel;

[0017] One end of the piezoresistive sensor extends into the second joint.

[0018] In a preferred technical solution of the present invention, the second connector is detachably connected to the first connector.

[0019] The rod body, as the main working part of the magnesium rod, is made of corrosion-resistant and easily sacrificed magnesium alloy material, and its shape and size are designed according to the specific needs of the water heater. The second joint is designed with a hole matching the mandrel inside, and is firmly connected to the rod body through the mandrel. The second joint is also designed with a connection structure matching the first joint, such as threads, buckles, etc., to achieve a detachable connection. The mandrel, as a connector between the rod body and the second joint, not only enhances the connection strength, but also facilitates the installation and disassembly of the magnesium rod body.

[0020] A second object of the present invention is to provide a water heater, comprising a water heater body, on which the magnesium rod assembly as described above is arranged.

[0021] The water heater not only has the traditional heating and water storage functions, but also improves the overall performance and user experience of the water heater by integrating an optimized magnesium rod and its consumption monitoring system. This water heater is not only safe, reliable and easy to maintain, but also can monitor the consumption of the magnesium rod in real time and remind users to replace it in time.

[0022] The third object of the present invention is to provide a method for monitoring consumption of a magnesium rod assembly, which method is implemented based on the water heater as described above;

[0023] The method comprises:

[0024] Get the current value I of the varistor sensor 实 ;

[0025] According to the current value I 实 Determine the remaining amount of magnesium rod;

[0026] When the remaining amount of the magnesium rod is less than the preset value of the magnesium rod, a reminder to replace the magnesium rod is issued.

[0027] The automatic monitoring and reminder function eliminates the need for users to manually check the status of the magnesium rod regularly, which improves the convenience and satisfaction of use. Timely reminders to replace the magnesium rod avoid the performance degradation or damage of the water heater due to the exhaustion of the magnesium rod, ensuring the daily life needs of users. By replacing the magnesium rod in time, the internal corrosion or scaling of the water heater that may be caused by the exhaustion of the magnesium rod is effectively prevented, thereby extending the overall service life of the water heater. The efficient use of magnesium rods reduces unnecessary waste and conforms to the green and environmentally friendly living concept.

[0028] In a preferred technical solution of the present invention, the magnesium rod preset value includes a first preset value and a second preset value, and the second preset value is smaller than the first preset value;

[0029] When the remaining amount of the magnesium rod is less than the preset value of the magnesium rod, a reminder to replace the magnesium rod is issued, including:

[0030] When the remaining amount of the magnesium rod is less than a first preset value, a first replacement reminder is issued;

[0031] If the magnesium rod is not replaced, the current value Ireal of the varistor sensor is continuously obtained to determine the remaining amount of the magnesium rod; the control system of the water heater obtains the current value Ireal of the varistor sensor periodically (such as every second, every minute, etc.). This current value reflects the current weight of the magnesium rod, and the remaining amount of the magnesium rod can be inferred.

[0032] When the remaining amount of the magnesium rod is less than a second preset value, a second replacement reminder is issued;

[0033] If the magnesium rod is not replaced, the equipment will shut down.

[0034] Two magnesium rod preset values ​​are set: a first preset value and a second preset value. The first preset value corresponds to a relatively high magnesium rod remaining amount threshold, while the second preset value corresponds to a lower threshold.

[0035] When the remaining amount of the magnesium rod is less than a first preset value, the control system issues a first replacement reminder, for example, by displaying a prompt message on a display screen, issuing a sound alarm, or sending a notification to the user's smart device.

[0036] If the user does not respond to the first replacement reminder and replace the magnesium rod, the control system continues to periodically obtain the current value I real of the varistor sensor and determines the remaining amount of the magnesium rod.

[0037] When the remaining amount of the magnesium rod is less than the second preset value, the control system issues a second replacement reminder, which may be more urgent and obvious to prompt the user to replace the magnesium rod immediately.

[0038] If the user still does not replace the magnesium rod, in order to ensure the safety of the water heater and prevent further damage, the control system shuts down the water heater and displays a corresponding error message.

[0039] In a preferred technical solution of the present invention, the current value I 实 Determine the remaining amount of magnesium rod, including:

[0040] Preset current value I 实 A relationship comparison table with the remaining amount of magnesium rods is used to determine the remaining amount of magnesium rods.

[0041] A fourth object of the present invention is to provide a method for monitoring consumption of a magnesium rod assembly, the method being implemented based on the water heater as described above;

[0042] The method comprises:

[0043] Power on every day to obtain the current value I1 of the varistor sensor;

[0044] Determine whether I1 is less than I0;

[0045] If not, continue to detect the current value I1. If yes, power on again the next day to obtain the current value I of the varistor sensor. 2， And determine whether the current value I2 is less than I0;

[0046] If not, continue to detect the current value I1; if yes, an alarm will remind the user to replace the magnesium rod;

[0047] Determine whether the user replaces the magnesium rod;

[0048] If yes, continue to detect the current value I1; if no, turn on the power to obtain the current value I of the varistor sensor 10 ;

[0049] Judgment I 10 Is it less than I 00 ;

[0050] If not, continue to detect the current value I 10 ; If yes, the alarm will remind the user to replace the magnesium rod;

[0051] Determine whether the user replaces the magnesium rod;

[0052] If yes, continue to detect the current value I1; if no, the device shuts down.

[0053] The beneficial effects of the present invention are:

[0054] The present invention provides a magnesium rod assembly and a water heater, wherein the magnesium rod comprises an assembly, and a varistor sensor is arranged on the assembly; when the magnesium rod is used, the varistor sensor is used to output a detection current value according to the weight of the assembly. During use, the magnesium rod is consumed from the outside to the inside. During the consumption process, magnesium ions gradually detach from the magnesium rod assembly, resulting in a reduction in the weight of the entire magnesium rod assembly. This change signal will be captured by the varistor sensor and converted into an electrical signal, thereby transmitting it to a display device using the magnesium rod. That is, when the magnesium rod is consumed, the weight becomes smaller and smaller, the voltage detected by the varistor will also become smaller and smaller, and the current value fed back to the display will also become smaller and smaller. Therefore, by monitoring the feedback voltage of the varistor detection, the remaining amount of the magnesium rod can be monitored in real time, and the user can be reminded to replace it in time when the magnesium rod is about to be exhausted. When the magnesium rod is in use, the user does not need to check the state of the magnesium rod regularly, and the system automatically monitors and reminds the replacement, which reduces the user's use burden and improves convenience and satisfaction. Timely replacement of the magnesium rod can avoid the performance degradation or damage of the water heater caused by the exhaustion of the magnesium rod, extend the overall service life of the water heater, and reduce maintenance costs.

[0055] The present application also provides a method for monitoring the consumption of a magnesium rod assembly. The method can determine the remaining amount of the magnesium rod by obtaining the current value of the varistor sensor, thereby achieving the purpose of real-time monitoring of the remaining amount of the magnesium rod. When there are only a few magnesium rods left, the user can be reminded to replace them in time to avoid the situation where the magnesium rods are completely consumed. The automatic monitoring method can also save the user the tedious steps of monitoring the status of the magnesium rods, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0065] In the design and use of air-energy water heaters, the anti-corrosion protection of water tanks is an important technical issue. When the water tank leaves the factory, it is usually equipped with a magnesium rod, which is sacrificed as an anode to protect the water tank and prevent the inner tank from corrosion. The magnesium rod protects the water tank by consuming itself. It is a consumable and needs to be replaced in time after consumption, otherwise the water tank may be corroded. At present, there are usually two ways in the industry to inform users whether the magnesium rod is: one is to tell customers how much time (for example, 3 years) after the water tank is installed to replace the magnesium rod; the second is to use big data analysis to measure the standard tap water quality of each water tank sales location, and then match the database according to the water tank installation location, so that it can be roughly determined how long the magnesium rod in the area is expected to be consumed, and then replace it regularly. Although these two solutions have solved the problem of magnesium rod replacement to a certain extent, they both have common disadvantages. First, these methods may lead to waste of magnesium rods, that is, the magnesium rods have not been consumed but the replacement time has come, or leave the water tank in an unprotected state, that is, the magnesium rods have been consumed but the replacement time has not yet come. Secondly, these two methods cannot obtain real-time monitoring of the remaining amount of magnesium rods, and cannot replace the magnesium rods immediately after they are consumed.

[0066] Based on this, the present application provides a magnesium rod assembly.

[0067] Example 1

[0068] like Figure 1-Figure 3 As shown, this embodiment provides a magnesium rod assembly, comprising:

[0069] A component body, on which a piezoresistive sensor 1 is arranged;

[0070] When the magnesium rod is used, the varistor sensor 1 is used to detect the current value flowing through the component.

[0071] Specifically, the magnesium rod is used in a water heater, and the varistor sensor 1 is selected to be a model that can accurately respond to small weight changes to ensure that it can sensitively capture the weight reduction of the magnesium rod during use. When the magnesium rod is brand new and unused, the varistor sensor 1 outputs a reference current value based on the initial weight of the assembly. As the magnesium rod is used in the water heater, magnesium ions gradually dissolve in the water, causing the overall weight of the magnesium rod assembly to gradually decrease. The varistor sensor 1 captures this weight change in real time and converts it into a corresponding electrical signal change, that is, the detection current value gradually decreases.

[0072] The water heater’s control system has a built-in algorithm that processes the sensor signal and converts it into an intuitive display of the remaining magnesium rod amount, such as a percentage or an estimated remaining usage time.

[0073] When the remaining amount of magnesium rod is lower than the preset threshold, the control system automatically triggers the reminder function and notifies the user to replace the magnesium rod through the water heater display or connected smart device (such as mobile phone APP). The system automatically monitors the status of the magnesium rod, without the need for manual inspection by the user, which greatly reduces the user's usage burden.

[0074] The automatic monitoring and reminder function eliminates the need for users to manually check the status of the magnesium rod regularly, improving the convenience of use and user satisfaction. Timely reminders to replace the magnesium rod avoid performance degradation or damage to the water heater due to magnesium rod exhaustion, ensuring the daily needs of users.

[0075] Furthermore, the component body includes a magnesium rod body 3 and a first joint 2 , the magnesium rod body 3 is detachably arranged on one side of the first joint 2 , and the varistor sensor 1 is detachably arranged on the first joint 2 .

[0076] The first joint 2 is used to connect the assembly to the water heater. More preferably, the first joint 2 is designed to be a structure that matches the magnesium rod body 3 to facilitate installation and disassembly of the magnesium rod body 3.

[0077] Furthermore, a sealing gasket 21 is provided on the first joint 2 , and the sealing gasket 21 is arranged on a side of the first joint 2 close to the magnesium rod body 3 .

[0078] The sealing gasket 21 is arranged on the first joint 2 in an annular shape, and is used to enhance the sealing performance of the first joint 2 during installation to prevent moisture from leaking from the first joint 2 .

[0079] More specifically, the magnesium rod body 3 includes a rod body 31 and a second joint 33, wherein the second joint 33 is disposed at one end of the rod body 31, and the second joint 33 is fixedly connected to the rod body 31 through a core shaft 32;

[0080] One end of the varistor sensor 1 extends into the second connector 33 .

[0081] Furthermore, the second connector 33 is detachably connected to the first connector 2 .

[0082] The rod body 31, as the main working part of the magnesium rod, is made of corrosion-resistant and easily sacrificed magnesium alloy material, and its shape and size are designed according to the specific needs of the water heater. The second joint 33 is designed with a channel matching the mandrel 32 inside, and is firmly connected to the rod body 31 through the mandrel 32. The second joint 33 is also designed with a connection structure matching the first joint 2, such as threads, buckles, etc., to achieve a detachable connection. The mandrel 32, as a connecting piece between the rod body 31 and the second joint 33, not only enhances the connection strength, but also facilitates the installation and disassembly of the magnesium rod body 3.

[0083] Example 2

[0084] like Figure 4 As shown, this embodiment provides a water heater, including a water heater body 10, on which the magnesium rod assembly as described above is arranged.

[0085] The water heater body 10 is the core part of the water heater, which is used to heat and store water. It is usually composed of an inner tank, an outer shell, a heating element, a control system, etc. The inner tank is the water storage part of the water heater, which is usually made of stainless steel or other corrosion-resistant materials to ensure the safety and sanitation of the water quality.

[0086] The outer shell protects the inner tank and heating element, while providing an aesthetically pleasing appearance and necessary thermal insulation. The heating element (such as an electric heating tube) is responsible for heating the water to ensure that the water heater can provide hot water at a constant temperature. The control system is responsible for monitoring and controlling various parameters of the water heater, such as water temperature and water volume, to ensure the normal operation of the water heater.

[0087] The second joint 33 is fixedly connected to the rod body 31 through the core shaft 32, and is designed with a connection structure matching the corresponding part on the water heater body 10, such as threads, snaps, etc., to achieve detachable installation of the magnesium rod on the water heater body 10.

[0088] One end of the varistor sensor 1 extends into the second joint 33, contacts a part of the rod body 31 or the mandrel 32, and is used to monitor the consumption of the magnesium rod. The output signal of the sensor is transmitted to the control system of the water heater through a wire or wirelessly. A part specifically used for installing the magnesium rod is provided on the water heater body 10, and the part matches the body joint of the magnesium rod to ensure that the magnesium rod can be firmly installed on the water heater. The control system of the water heater is connected to the varistor sensor 1 on the magnesium rod, and receives and processes the signal transmitted by the sensor in real time to monitor the remaining amount and consumption of the magnesium rod. When the remaining amount of the magnesium rod is lower than the preset threshold, the control system of the water heater automatically triggers the reminder function, and reminds the user to replace the magnesium rod in time through a display screen, sound or a connected smart device (such as a mobile phone APP).

[0089] When the water heater is working normally, the heating element heats the water, and the control system monitors the water temperature and adjusts the heating power to maintain a constant temperature. At the same time, the magnesium rod acts as a sacrificial anode to protect the inner tank from corrosion.

[0090] The varistor sensor 1 monitors the consumption of the magnesium rod in real time and transmits the signal to the control system. The control system calculates the remaining amount of the magnesium rod based on the received signal and reminds the user to replace it when necessary.

[0091] The water heater not only has the traditional heating and water storage functions, but also improves the overall performance and user experience of the water heater by integrating an optimized magnesium rod and its consumption monitoring system. This water heater is not only safe, reliable and easy to maintain, but also can monitor the consumption of the magnesium rod in real time and remind users to replace it in time.

[0092] Example 3

[0093] like Figure 5 As shown, this embodiment provides a method for monitoring consumption of a magnesium rod assembly, which is implemented based on the water heater as described above;

[0094] The method comprises:

[0095] S100, obtaining the current value I of the varistor sensor 1 实 ;

[0096] S200, according to the current value I 实 Determine the remaining amount of magnesium rod;

[0097] In a specific implementation manner, the current value I 实 Determine the remaining amount of magnesium rod, including:

[0098] Preset current value I 实 A relationship comparison table with the remaining amount of magnesium rods is used to determine the remaining amount of magnesium rods.

[0099] This relationship table can be established through experimental data or information provided by the manufacturer, which describes the remaining amount of magnesium rods corresponding to different current values. The control system is based on the current value I 实 , find the corresponding remaining amount of magnesium rod in the relationship comparison table.

[0100] S300: When the remaining amount of the magnesium rod is less than the preset value of the magnesium rod, a reminder to replace the magnesium rod is issued.

[0101] The automatic monitoring and reminder function of the magnesium rod in this method eliminates the need for users to manually check the status of the magnesium rod regularly, thereby improving the convenience and satisfaction of use. Timely reminders to replace the magnesium rod avoid the performance degradation or damage of the water heater caused by the exhaustion of the magnesium rod, and ensure the daily life needs of users. By replacing the magnesium rod in time, the internal corrosion or scaling of the water heater that may be caused by the exhaustion of the magnesium rod is effectively prevented, thereby extending the overall service life of the water heater. The efficient use of magnesium rods reduces unnecessary waste and conforms to the green and environmentally friendly life concept.

[0102] More specifically, the magnesium rod preset value includes a first preset value and a second preset value, and the second preset value is smaller than the first preset value;

[0103] When the remaining amount of the magnesium rod is less than the preset value of the magnesium rod, a reminder to replace the magnesium rod is issued, including:

[0104] When the remaining amount of the magnesium rod is less than a first preset value, a first replacement reminder is issued;

[0105] If the magnesium rod is not replaced, continue to obtain the current value I of the varistor sensor 1 实 , and determine the remaining amount of magnesium rods; the control system of the water heater regularly (such as every second, every minute, etc.) obtains the current value I of the varistor sensor 1 实 This current value reflects the current weight of the magnesium rod, and the remaining amount of the magnesium rod can be inferred.

[0106] When the remaining amount of the magnesium rod is less than a second preset value, a second replacement reminder is issued;

[0107] If the magnesium rod is not replaced, the equipment will shut down.

[0108] The method sets two magnesium rod preset values: a first preset value and a second preset value. The first preset value corresponds to a relatively high magnesium rod remaining amount threshold, while the second preset value corresponds to a lower threshold.

[0109] When the remaining amount of the magnesium rod is less than a first preset value, the control system issues a first replacement reminder, for example, by displaying a prompt message on a display screen, issuing a sound alarm, or sending a notification to the user's smart device.

[0110] If the user does not respond to the first replacement reminder and replace the magnesium rod, the control system continues to periodically obtain the current value I of the varistor sensor 1. 实 , and determine the remaining amount of magnesium rod.

[0111] When the remaining amount of the magnesium rod is less than the second preset value, the control system issues a second replacement reminder, which may be more urgent and obvious to prompt the user to replace the magnesium rod immediately.

[0112] If the user still does not replace the magnesium rod, in order to ensure the safety of the water heater and prevent further damage, the control system shuts down the water heater and displays a corresponding error message.

[0113] Example 4

[0114] like Figure 6 As shown, this embodiment provides a method for monitoring consumption of a magnesium rod assembly, which is implemented based on the water heater as described above;

[0115] The method comprises:

[0116] Power on every day to obtain the current value I1 of the varistor sensor 1;

[0117] Determine whether I1 is less than I0;

[0118] If not, continue to detect the current value I1. If yes, power on again the next day to obtain the current value I2 of the varistor sensor 1, and determine whether the current value I2 is less than I0;

[0119] If not, continue to detect the current value I1; if yes, an alarm will remind the user to replace the magnesium rod;

[0120] Determine whether the user replaces the magnesium rod;

[0121] If yes, continue to detect the current value I1; if no, turn on the power to obtain the current value I1 of the varistor sensor 1. 10 ;

[0122] Judgment I 10 Is it less than I 00 ;

[0123] If not, continue to detect the current value I 10 ; If yes, the alarm will remind the user to replace the magnesium rod;

[0124] Determine whether the user replaces the magnesium rod;

[0125] If yes, continue to detect the current value I1; if no, the device shuts down.

[0126] The magnesium rod assembly consumption monitoring method provided in this embodiment is as follows:

[0127] First, set the initial current values ​​I0 and I 00 , I0 and I 00 Can be obtained through experiments.

[0128] I0 is the threshold for judging that the magnesium rod begins to be consumed significantly, and I00 is the emergency threshold for judging that the magnesium rod is about to be exhausted.

[0129] Make sure the water heater and magnesium rod assembly are installed correctly and that varistor sensor 1 is working properly.

[0130] The current value I1 of the varistor sensor 1 is obtained by powering on the sensor every day.

[0131] Determine whether I1 is less than I0. If I1 is not less than I0, it means that the consumption of magnesium rods is not significant, and continue to test I1 daily.

[0132] If I1 is less than I0, it means that the magnesium rod begins to be consumed significantly, and go to the next step for confirmation.

[0133] The next day, the power is turned on again to obtain the current value I2 of the varistor sensor 1.

[0134] Determine whether I2 is less than I0. If I2 is not less than I0, it may be a false alarm or the magnesium rod consumption is slow, and continue to return to the daily monitoring stage.

[0135] If I2 is less than I0, it is confirmed that the magnesium rod is indeed being consumed significantly, and an alarm is issued to remind the user to replace the magnesium rod.

[0136] Determine whether the user has replaced the magnesium rod. If the user has replaced it, reset the monitoring process and continue to detect I1 daily.

[0137] If the user does not change it, enter the emergency monitoring stage.

[0138] In the emergency monitoring stage, the current value I of the varistor sensor 1 is obtained by powering on. 10 .

[0139] Judgment I 10 Is it less than I 00 If I 10 Not less than I 10 This means that although the magnesium rods are consumed, it has not yet reached an emergency level. Continue to monitor I 10 .

[0140] If I 10 Less than I 00 , indicating that the magnesium rod is about to be exhausted, and the alarm will be sounded again to remind the user to replace the magnesium rod immediately.

[0141] Determine whether the user has responded to the emergency alarm and replaced the magnesium rod. If the user has replaced it, reset the monitoring process and continue daily detection I1.

[0142] If the user does not replace it, in order to protect the water heater from further damage, the device automatically shuts down and displays a corresponding error message or alarm.

In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0144] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0145] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this application. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
