Description

Technical Field

[0001] The present invention relates to the technical field of ohmic heating, and in particular to a control method and device for ohmic heating equipment, electronic equipment, and a storage medium. Background Art

[0002] As a new trend in cooking methods today, ohmic heating has been increasingly used in various cooking and sterilization methods. Its principle is to use direct contact between electrodes and food, and the resistance of the food itself to quickly heat up and quickly reach the target temperature. It can cook or sterilize without destroying the original characteristics of the food. It has been widely used in food processing methods such as quick cooking and pasteurization.

[0003] Since ohmic heating is in direct contact with the food to be processed, contamination by residual food is inevitable. Long-term use will also cause the heating speed to slow down. If it is not cleaned in time, the electrode will become more difficult to clean after multiple uses and may even fail to work normally. In addition, the continuous operation of the electrode will inevitably lead to oxidation, which will also affect the service life of the electrode.

[0004] However, when using traditional cleaning methods to brush the board, such as ordinary water flushing, although it can clean food residues that are not strongly adhered, some food may adhere to the electrode and be ignored by the user. Traditional cleaning methods are also difficult to effectively clean the electrode oxidation phenomenon; and if the above situation is not cleaned in time, the service life will be greatly reduced, but users often do not know whether the electrode itself is contaminated and the degree of electrode contamination, and it is easy to miss the best time for targeted cleaning.

[0048] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. This is only for the purpose of clearly describing the technical solutions of the embodiments of the present application, and shall not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0050] In the embodiments of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0051] Ohmic heating, as a new trend in cooking methods today, has been increasingly used in various cooking and sterilization methods. Its principle is to use the direct contact between the electrode and the food, and the resistance of the food itself to quickly heat up and quickly reach the target temperature. It can be cooked or sterilized without destroying the original characteristics of the food. It has been widely used in food processing methods such as quick cooking and pasteurization. However, it is precisely because of this direct contact method that the electrode is easily contaminated by food, which will cause the heating speed to slow down after long-term use. If it is not cleaned in time, it will be more difficult to clean the electrode after multiple uses, and it may even fail to work properly. In addition, the continuous operation of the electrode will inevitably lead to oxidation, which will also affect the service life of the electrode.

[0052] If the traditional cleaning method is used to brush the board, it will not only cause trouble, but also may not pay attention to the use of the electrode in time. It is not only inconvenient to operate but also consumes unnecessary energy of the user. For example, ordinary water flushing may be able to clean food residues that are not strongly adhered, but some food may adhere to the electrode and cannot be removed well without special tools for brushing. In addition, if the brushing force is too strong, it may damage the electrode.

[0053] In the related art, the mainstream maintenance method for electrodes is to clean them physically using a brush. However, for electrodes installed inside containers, the brush is inconvenient to operate, and some dead corners are difficult to clean. However, if the structure is designed to be easy to disassemble, the connection will be unstable, resulting in a decrease in the ohmic heating effect. The judgment of electrode contamination is more of a manual observation, and users make their own judgment based on usage. In this way, untimely cleaning may lead to poor ohmic heating effect.

[0054] In order to solve the above problems, the present invention is based on the core technical concept of determining the electrode contamination phenomenon according to the food heating rate in actual use and the heating rate corresponding to the same type of food in the heating rate database, and improves the control method of the ohmic heating device in the related art. The present invention will be described in detail in conjunction with the accompanying drawings as follows:

[0055] Reference Figure 1 , shows a flowchart of a method for controlling an ohmic heating device provided by some embodiments of the present invention, which may specifically include the following steps:

[0056] Step 101, determining a heating rate database of the ohmic heating device under normal working conditions;

[0057] In a specific implementation, the heating rate database of the ohmic heating device under normal working conditions can be first determined as a reference in actual use. Specifically, the heating rate information set corresponding to the first heating of different types of food by the ohmic heating device and the heating rate information set corresponding to different types of food in the network database can be obtained to establish a heating rate database of the ohmic heating device under normal working conditions.

[0058] In some embodiments of the present invention, determining the heating rate database of the ohmic heating device under normal working conditions includes:

[0059] Acquire a first heating rate information set corresponding to the first heating of different types of food by the ohmic heating device and a second heating rate information set corresponding to different types of food in a network database;

[0060] A heating rate database of the ohmic heating device under normal working conditions is determined according to the first heating rate information set and / or the second heating rate information set.

[0061] In practical applications, when the ohmic heating device heats different types of food for the first time, the heating rates when heated to a preset temperature can be recorded separately to obtain a first heating rate information set, and the average food heating rates corresponding to the different types of food recorded can be obtained from the network database to obtain a second heating rate information set; and then, based on the first heating rate information set and / or the second heating rate information set, a heating rate database of the ohmic heating device under normal working conditions can be established to improve the accuracy of subsequent judgment on the electrode contamination status.

[0062] Step 102, in response to a start-up operation of the ohmic heating device, determining a food type of food in the ohmic heating device;

[0063] In a specific implementation, the type of food placed in the ohmic heating device can be confirmed in time in response to the user's startup operation on the ohmic heating device. Specifically, through a Raspberry Pi and a camera, the food placed in the ohmic heating device can be first identified and trained using a network database, and the user's own database can be established during use. Through a large number of training and learning iterations, the ohmic heating device can achieve high-precision recognition of the same type of food.

[0064] Step 103, determining a first heating rate when the ohmic heating device heats the food, and obtaining a second heating rate corresponding to the same type of food in the heating rate database;

[0065] In actual applications, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined when the ohmic heating device heats the food, and the second heating rate corresponding to the same food type can be obtained from the heating rate database based on the food type determined in the previous step for use in the subsequent electrode contamination phenomenon judgment process.

[0066] Step 104, judging whether there is electrode contamination in the ohmic heating device according to the first heating rate and the second heating rate;

[0067] In a specific implementation, it can be determined whether the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold; if the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to the first preset threshold, it is determined that there is electrode contamination in the ohmic heating device. For example, when the first heating rate is 5% or more slower than the second heating rate recorded in the heating rate database, it can be determined that the electrodes of the ohmic heating device are contaminated. In addition, in order to enhance the accuracy of the judgment, it is not necessary to determine that the electrodes of the ohmic heating device are contaminated only through one judgment. When the actual heating rate of the same food type is 5% or more slower than the corresponding heating rate recorded in the heating rate database for three consecutive times, it can be determined that the electrodes of the ohmic heating device are contaminated, so as to avoid misjudgment affecting the user's experience.

[0068] In some embodiments of the present invention, judging whether the ohmic heating device has electrode contamination according to the first heating rate and the second heating rate includes:

[0069] Determining whether the first heating rate is less than the second heating rate and whether the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold;

[0070] If the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold, it is determined that the ohmic heating device has electrode contamination.

[0071] In actual applications, it can be determined whether the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold; if the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to the first preset threshold, it is determined that the ohmic heating device has electrode contamination. For example, when the first heating rate is 5% or more slower than the second heating rate recorded in the heating rate database, it can be determined that the electrodes of the ohmic heating device are contaminated. In addition, in order to enhance the accuracy of the judgment, it is not necessary to determine that the electrodes of the ohmic heating device are contaminated through more than one judgment. It is also possible to only record the first time that the first heating rate is 5% or more slower than the second heating rate recorded in the heating rate database. And when the actual heating rate of the same food type is 5% or more slower than the corresponding heating rate recorded in the heating rate database for three consecutive times, it is determined that the electrodes of the ohmic heating device are contaminated, so as to avoid misjudgment affecting the user's experience.

[0072] Step 105: If it is determined that the ohmic heating device has the electrode contamination phenomenon, the user is notified to clean the ohmic heating device.

[0073] In a specific implementation, the judgment result can be used to inform the user through a display screen, a buzzer, or a mobile phone-related APP that the ohmic heating device should be cleaned, thereby extending the service life of the device through timely cleaning and maintenance;

[0074] Furthermore, in order to facilitate users to clean the ohmic heating equipment, the characteristics of the ohmic heating equipment can be used to clean the ohmic heating equipment using glow discharge. This can not only clean the electrodes, but also maintain the cleanliness of the inside of the equipment. Compared with traditional physical cleaning methods, it can remove pollutants more thoroughly without the need for users to perform too much operation, thereby reducing labor costs and improving the user experience.

[0075] In some embodiments of the present invention, the method further comprises:

[0076] In response to the user's electrode cleanliness self-checking operation, determining a third heating rate corresponding to the water heating performed by the ohmic heating device, and obtaining a fourth heating rate corresponding to the water heating in the heating rate database;

[0077] Determining whether there is electrode contamination in the ohmic heating device according to the third heating rate and the fourth heating rate;

[0078] If it is determined that the ohmic heating device has the electrode contamination phenomenon, the user is notified to clean the ohmic heating device.

[0079] In a specific implementation, a self-check function for the cleanliness of the ohmic heating device can also be provided to the user. Specifically, before the device leaves the factory, 70% of the volume of water of the device capacity can be added to the food processing container of the ohmic heating device through experiments and other methods, and heated to boiling through ohmic heating, and the duration of the process is recorded in the heating rate database as a detection benchmark data; when the user wants to use the self-check function for the cleanliness of the ohmic heating device, 70% of the volume of water of the device capacity can be added to the food processing container of the ohmic heating device according to the scale and other information marked on the device, and heated to boiling through ohmic heating, the duration is recorded and compared with the detection benchmark data established in the heating rate database; it is determined whether the electrode is contaminated and whether the heating efficiency of the electrode is affected. If it is determined that the electrode is contaminated, the result can also be judged through the display screen, buzzer or mobile phone-associated APP to inform the user that the ohmic heating device should be cleaned, thereby extending the service life of the equipment through timely cleaning and maintenance.

[0080] In some embodiments of the present invention, the method further comprises:

[0081] In response to a user's operation to start the electrode cleaning function, a glow discharge process is performed on the electrode in the ohmic heating device to clean the electrode and the inner wall of the container of the ohmic heating device.

[0082] In actual applications, a vacuum pump can be pre-installed in the ohmic heating equipment, so that when the user's electrode cleaning function is turned on, the air pressure conditions in the container can be changed to a pressure suitable for glow discharge through the vacuum pump. Generally speaking, glow discharge can only be stably discharged under low pressure. Therefore, when starting the cleaning work, the air pressure in the container can be adjusted to between 12 and 22 kPa to meet the glow discharge conditions.

[0083] Furthermore, after the gas pressure meets the glow discharge conditions, the electrodes in the ohmic heating device can be glow discharged. Specifically, the power supply of the ohmic heating device can be converted into alternating current, and the frequency and voltage of the power supply can be adjusted to a preset target range. Generally speaking, the electric field condition of ohmic heating is direct current, and the voltage is adjusted according to the different heating speeds required for different foods, usually at the daily power voltage or even lower. When glow discharge cleaning and disinfection is required, the power supply can be converted into alternating current, and the frequency can be increased to 10kHz to 100kHz, while the power supply voltage can be increased to the kV level, thereby performing glow discharge cleaning and disinfection.

[0084] Furthermore, after the glow discharge treatment is completed, the waste generated by the cleaning in the previous steps can be removed by water flushing treatment and the like to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water flushing treatment can be pre-set to be automatically performed in the corresponding pipeline, or the user can be notified that the glow discharge has been completed and the ohmic heating equipment needs to be water flushed.

[0085] In some embodiments of the present invention, the ohmic heating device at least includes a vacuum pump, and before the glow discharge treatment is performed on the electrode in the ohmic heating device, the method further includes:

[0086] The vacuum pump is used to adjust the air pressure of the ohmic heating device so that the inside of the ohmic heating device meets the glow discharge condition.

[0087] In a specific implementation, a vacuum pump can be pre-installed in the ohmic heating device, so that when the user's electrode cleaning function is turned on, the air pressure conditions in the container can be changed to a pressure suitable for glow discharge through the vacuum pump. Generally speaking, glow discharge can only be stably discharged under low pressure. Therefore, when starting the cleaning work, the air pressure in the container can be adjusted to between 12 and 22 kPa to meet the glow discharge conditions.

[0088] In some embodiments of the present invention, the glow discharge treatment of the electrode in the ohmic heating device comprises:

[0089] The power supply of the ohmic heating device is converted into alternating current, and the frequency and voltage of the power supply are adjusted to a preset target range.

[0090] In actual applications, after the gas pressure meets the glow discharge conditions, the electrodes in the ohmic heating equipment can be glow discharged. Specifically, the power supply of the ohmic heating equipment can be converted into alternating current, and the frequency and voltage of the power supply can be adjusted to a preset target range. Generally speaking, the electric field condition of ohmic heating is direct current, and the voltage is adjusted according to the different heating speeds required for different foods, usually at the daily power voltage or even lower. When glow discharge cleaning and disinfection is required, the power supply can be converted into alternating current, and the frequency can be increased to 10kHz to 100kHz, while the power supply voltage can be increased to the kV level, thereby performing glow discharge cleaning and disinfection.

[0091] In some embodiments of the present invention, after performing glow discharge treatment on the electrodes in the ohmic heating device, the method further comprises:

[0092] Notify the user to flush the ohmic heating device with water.

[0093] In a specific implementation, after the glow discharge treatment is completed, the waste generated by the cleaning in the previous steps can be removed by water flushing and the like to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water flushing treatment can be pre-set to be automatically performed in the corresponding pipeline, or the user can be notified that the glow discharge is completed and the ohmic heating equipment needs to be flushed with water, thereby ensuring that there are no residual contaminants in the equipment after the glow discharge, thereby enhancing the service life of the equipment and the safety of subsequent food processing.

[0094] Reference Figure 2 , shows a flowchart of another method for controlling an ohmic heating device provided by some embodiments of the present invention, which may specifically include the following steps:

[0095] Step 201, obtain a first heating rate information set corresponding to when the ohmic heating device heats different types of food for the first time and a second heating rate information set corresponding to different types of food in a network database; and determine a heating rate database of the ohmic heating device under normal working conditions based on the first heating rate information set and / or the second heating rate information set.

[0096] In practical applications, when the ohmic heating device heats different types of food for the first time, the heating rates when heated to a preset temperature can be recorded separately to obtain a first heating rate information set, and the average food heating rates corresponding to the different types of food recorded can be obtained from the network database to obtain a second heating rate information set; and then, based on the first heating rate information set and / or the second heating rate information set, a heating rate database of the ohmic heating device under normal working conditions can be established to improve the accuracy of subsequent judgment on the electrode contamination status.

[0097] Step 202, in response to a start-up operation of the ohmic heating device, determining a food type of food in the ohmic heating device;

[0098] In a specific implementation, the type of food placed in the ohmic heating device can be confirmed in time in response to the user's startup operation on the ohmic heating device. Specifically, through a Raspberry Pi and a camera, the food placed in the ohmic heating device can be first identified and trained using a network database, and the user's own database can be established during use. Through a large number of training and learning iterations, the ohmic heating device can achieve high-precision recognition of the same type of food.

[0099] Step 203, determining a first heating rate when the ohmic heating device heats the food, and obtaining a second heating rate corresponding to the same type of food in the heating rate database;

[0100] In actual applications, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined when the ohmic heating device heats the food, and the second heating rate corresponding to the same food type can be obtained from the heating rate database based on the food type determined in the previous step for use in the subsequent electrode contamination phenomenon judgment process.

[0101] Step 204, determine whether the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold; if the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to the first preset threshold, it is determined that the ohmic heating device has electrode contamination.

[0102] Step 205: If it is determined that the ohmic heating device has the electrode contamination phenomenon, the user is notified to clean the ohmic heating device.

[0103] In a specific implementation, the judgment result can be used to inform the user through a display screen, a buzzer, or a mobile phone-related APP that the ohmic heating device should be cleaned, thereby extending the service life of the device through timely cleaning and maintenance;

[0104] Furthermore, in order to facilitate users to clean the ohmic heating equipment, the characteristics of the ohmic heating equipment can be used to clean the ohmic heating equipment using glow discharge. This can not only clean the electrodes, but also maintain the cleanliness of the inside of the equipment. Compared with traditional physical cleaning methods, it can remove pollutants more thoroughly without the need for users to perform too much operation, thereby reducing labor costs and improving the user experience.

[0105] Reference Figure 3 , shows a flowchart of another method for controlling an ohmic heating device provided by some embodiments of the present invention, which may specifically include the following steps:

[0106] Step 301, determining a heating rate database of the ohmic heating device under normal working conditions;

[0107] In a specific implementation, the heating rate database of the ohmic heating device under normal working conditions can be first determined as a reference in actual use. Specifically, the heating rate information set corresponding to the first heating of different types of food by the ohmic heating device and the heating rate information set corresponding to different types of food in the network database can be obtained to establish a heating rate database of the ohmic heating device under normal working conditions.

[0108] Step 302, in response to the start-up operation of the ohmic heating device, determining the food type of the food in the ohmic heating device;

[0109] In a specific implementation, the type of food placed in the ohmic heating device can be confirmed in time in response to the user's startup operation on the ohmic heating device. Specifically, through a Raspberry Pi and a camera, the food placed in the ohmic heating device can be first identified and trained using a network database, and the user's own database can be established during use. Through a large number of training and learning iterations, the ohmic heating device can achieve high-precision recognition of the same type of food.

[0110] Step 303, determining a first heating rate when the ohmic heating device heats the food, and obtaining a second heating rate corresponding to the same type of food in the heating rate database;

[0111] In actual applications, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined when the ohmic heating device heats the food, and the second heating rate corresponding to the same food type can be obtained from the heating rate database based on the food type determined in the previous step for use in the subsequent electrode contamination phenomenon judgment process.

[0112] Step 304, judging whether there is electrode contamination in the ohmic heating device according to the first heating rate and the second heating rate;

[0113] In a specific implementation, it can be determined whether the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to a first preset threshold; if the first heating rate is less than the second heating rate and the difference between the second heating rate and the first heating rate is greater than or equal to the first preset threshold, it is determined that there is electrode contamination in the ohmic heating device. For example, when the first heating rate is 5% or more slower than the second heating rate recorded in the heating rate database, it can be determined that the electrodes of the ohmic heating device are contaminated. In addition, in order to enhance the accuracy of the judgment, it is not necessary to determine that the electrodes of the ohmic heating device are contaminated only through one judgment. When the actual heating rate of the same food type is 5% or more slower than the corresponding heating rate recorded in the heating rate database for three consecutive times, it can be determined that the electrodes of the ohmic heating device are contaminated, so as to avoid misjudgment affecting the user's experience.

[0114] Pollution, to avoid misjudgment affecting the user experience.

[0115] Step 305: If it is determined that the ohmic heating device has the electrode contamination phenomenon, the user is notified to clean the ohmic heating device.

[0116] In a specific implementation, the judgment result can be used to inform the user through a display screen, a buzzer, or a mobile phone-related APP that the ohmic heating device should be cleaned, thereby extending the service life of the device through timely cleaning and maintenance;

[0117] Furthermore, in order to facilitate users to clean the ohmic heating equipment, the characteristics of the ohmic heating equipment can be used to clean the ohmic heating equipment using glow discharge. This can not only clean the electrodes, but also maintain the cleanliness of the inside of the equipment. Compared with traditional physical cleaning methods, it can remove pollutants more thoroughly without the need for users to perform too much operation, thereby reducing labor costs and improving the user experience.

[0118] Step 306 , in response to the user's operation to start the electrode cleaning function, glow discharge treatment is performed on the electrode in the ohmic heating device to clean the electrode and the inner wall of the container of the ohmic heating device.

[0119] In actual applications, a vacuum pump can be pre-installed in the ohmic heating equipment, so that when the user's electrode cleaning function is turned on, the air pressure conditions in the container can be changed to a pressure suitable for glow discharge through the vacuum pump. Generally speaking, glow discharge can only be stably discharged under low pressure. Therefore, when starting the cleaning work, the air pressure in the container can be adjusted to between 12 and 22 kPa to meet the glow discharge conditions.

[0120] Furthermore, after the gas pressure meets the glow discharge conditions, the electrodes in the ohmic heating device can be glow discharged. Specifically, the power supply of the ohmic heating device can be converted into alternating current, and the frequency and voltage of the power supply can be adjusted to a preset target range. Generally speaking, the electric field condition of ohmic heating is direct current, and the voltage is adjusted according to the different heating speeds required for different foods, usually at the daily power voltage or even lower. When glow discharge cleaning and disinfection is required, the power supply can be converted into alternating current, and the frequency can be increased to 10kHz to 100kHz, while the power supply voltage can be increased to the kV level, thereby performing glow discharge cleaning and disinfection.

[0121] Furthermore, after the glow discharge treatment is completed, the waste generated by the cleaning in the previous steps can be removed by water flushing treatment and the like to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water flushing treatment can be pre-set to be automatically performed in the corresponding pipeline, or the user can be notified that the glow discharge has been completed and the ohmic heating equipment needs to be water flushed.

[0122] The following will be combined Figure 4 and Figure 5 The embodiments of the present invention are further described as follows:

[0123] Reference Figure 4 The overall execution process of the ohmic heating device control method provided by the present invention can be summarized as the following two processes: the user starts the device normally and the user starts the self-check function; and before executing the above process, the temperature rise self-check standard of the device can be pre-set before leaving the factory;

[0124] Specifically, the process of starting the device for normal use by a user may include the following steps: step one, starting the device; step two, recording the heating rates of different foods; step three, determining whether the heating rates of the same type of food differ by 5% or more; if the heating rates of the same type of food differ by 5% or more, notifying the user to clean up; if the heating rates of the same type of food do not differ by 5% or more, cooking is completed normally; step four, shutting down the device.

[0125] Furthermore, the process of the user starting the self-check function may include the following steps: step 1, start the self-check, step 2, add 70% water and heat to boiling, step 3, determine whether it differs from the set standard by 5% or more, if it differs from the set standard by 5% or more, notify the user to clean up, if it does not differ from the set standard by 5% or more, then the shutdown operation can be performed directly. The exemplary descriptions of the above steps have been described in the above content, and will not be repeated here.

[0126] Further, see Figure 5The overall process of glow discharge cleaning in the present invention can be summarized as follows: step 1, start cleaning mode, step 2, start vacuum pump, step 3, glow discharge cleaning; step 4, water flushing; step 5, shut down. Similarly, the exemplary descriptions of the above steps have been described in the above content, and will not be repeated here.

[0127] The present invention provides an ohmic heating device control method and device, an electronic device, and a storage medium. The basic working principle is to record the heating rate of the same type of food. If the heating rate of the same type of food is 5% or more slower than the initially recorded heating rate or the common heating rate for three consecutive times, it can be determined that the electrode of the ohmic heating device is contaminated and needs to be cleaned; and a second detection method can be provided, that is, the user can select the detection by himself. When designing the ohmic heating container, the time for ohmic heating of 70% of the container capacity to boil can be set in advance through experimental data under a new condition, and it is set as a standard range threshold. When the user selects the detection electrode, ohmic heating of 70% of the container capacity of water can be added to the container again to boil. If the heating rate slows down by 5%, it is determined that it is contaminated and needs to be cleaned. If the detection result is that it is contaminated and needs to be cleaned, a prompt can be issued to the user to clean the electrode. If the user chooses to clean, the true air pump can be used to evacuate the inside of the device and perform glow discharge to clean the inside of the container and the electrode after the use is completed, or the user can wait for the user to select a time to perform glow discharge to clean the electrode after the user refuses, thereby completing the monitoring and cleaning of the electrode contamination degree.
