Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ohmic heating, in particular to an ohmic heating equipment control method and device, electronic equipment and storage medium. BACKGROUND

[0002] As a new trend of cooking methods, ohmic heating has been increasingly applied to various cooking methods and disinfection methods. The principle is to directly contact the electrode with the food, heat the food through its own resistance, quickly reach the target temperature, and cook or disinfect without destroying the original characteristics of the food. It has been widely used in food processing methods such as rapid cooking and pasteurization.

[0003] Since ohmic heating is directly in contact with the food to be processed, contamination by residual food is inevitable. Long-term use will also slow down the heating speed, and if not cleaned in time, the electrode will be difficult to clean or even unable to work normally after multiple uses. In addition, the continuous work 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 clean the plate, for example, although the ordinary water flow can clean the food residue that is not strongly attached, some food may be attached to the electrode and ignored by the user, and the traditional cleaning method is also difficult to effectively clean the phenomenon of electrode oxidation. If the above situation is not cleaned in time, the service life will be greatly reduced, but the user often does not know whether the electrode is contaminated and the degree of electrode contamination, and is easy to miss the best time for targeted cleaning.

[0048] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0049] In the embodiments of this application, the terms "first" and "second" are used to distinguish identical or similar items with essentially the same function and effect, only for the purpose of clearly describing the technical solution of the embodiments of this application, and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0050] In the embodiments of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Ohmic heating, a new trend in modern cooking, is increasingly being used in various cooking and sterilization methods. Its principle involves direct contact between electrodes and food, utilizing the food's resistance to rapidly raise the temperature to the target level. This allows for cooking or sterilization without damaging the food's original properties and is widely used in food processing methods such as rapid cooking and pasteurization. However, this direct contact method makes the electrodes susceptible to food contamination. Prolonged use can lead to slower heating speeds, and if not cleaned regularly, repeated use can make cleaning more difficult and even cause the electrodes to malfunction. Furthermore, continuous use inevitably leads to oxidation, which also affects the electrodes' lifespan.

[0052] Using traditional cleaning methods to brush the electrodes is not only troublesome, but may also lead to situations where the electrodes are not monitored in time. It is not only inconvenient to operate, but also wastes unnecessary energy for the user. For example, ordinary water rinsing may be able to remove food residue that is not strongly attached, but some food may stick to the electrodes and cannot be removed well without special tools. In addition, if the brushing force is too strong, it may damage the electrodes.

[0053] In related technologies, the mainstream method for electrode maintenance is to clean them using physical methods such as brushes. However, brushes are inconvenient to operate on electrodes installed inside containers, and some hard-to-reach corners are difficult to clean. If the structure is designed to be easy to disassemble, the connection may be unstable, resulting in a decrease in ohmic heating effect. As for judging electrode contamination, it is mostly done by human observation, and users judge it themselves based on usage. This can lead to situations where cleaning is not timely, resulting in poor ohmic heating effect.

[0054] To address the aforementioned problems, this invention, based on the core technical concept of determining electrode contamination by comparing the actual food heating rate with the corresponding heating rate of the same food type in a heating rate database, improves upon the ohmic heating device control method in related technologies. The invention will be described in detail below with reference to the accompanying drawings:

[0055] Reference Figure 1 The diagram illustrates a flowchart of a control method for an ohmic heating device according to some embodiments of the present invention, which may specifically include the following steps:

[0056] Step 101: Determine the heating rate database under normal operating conditions of the ohmic heating device;

[0057] In practical implementation, the heating rate database under normal operating conditions of the ohmic heating device can be determined first as a reference for 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 the heating rate database under normal operating conditions of the ohmic heating device.

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

[0059] Obtain 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 the network database;

[0060] Based on the first heating rate information set and / or the second heating rate information set, a heating rate database under normal operating conditions of the ohmic heating device is determined.

[0061] In practical applications, the heating rate at which different types of food are heated to a preset temperature can be recorded when the ohmic heating device first heats them to obtain a first heating rate information set. The average heating rate of different types of food recorded in the network database can be obtained to obtain a second heating rate information set. Then, a heating rate database under normal operating conditions of the ohmic heating device can be established based on the first heating rate information set and / or the second heating rate information set, thereby improving the accuracy of subsequent judgment on electrode contamination status.

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

[0063] In practical implementation, the device can respond to the user's activation of the ohmic heating device and promptly identify the type of food placed inside. Specifically, this can be achieved by using a Raspberry Pi and a camera to first identify and train the device using a network database, and then building the user's own database during use. Through extensive training and iteration, the ohmic heating device can achieve high-precision identification of the same type of food.

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

[0065] In practical applications, when heating food with an ohmic heating device, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined, 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 steps, for use in the subsequent electrode contamination phenomenon judgment process.

[0066] Step 104: Determine whether the ohmic heating device has electrode contamination based on the first heating rate and the second heating rate;

[0067] In specific implementation, it can be determined 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. 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 only possible to determine that the electrodes of the ohmic heating device are contaminated by a single judgment, but also when the actual heating rate of the same type of food 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, thus avoiding misjudgment and affecting the user experience.

[0068] In some embodiments of the present invention, determining whether the ohmic heating device exhibits electrode contamination based on the first heating rate and the second heating rate includes:

[0069] Determine 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 the first preset threshold, then it is determined that the ohmic heating device has electrode contamination.

[0071] In practical applications, it can be determined 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. 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, to enhance the accuracy of the judgment, it is not necessary to determine that the electrodes of the ohmic heating device are contaminated by a single judgment. It is also possible to record only when the first heating rate is 5% or more slower than the second heating rate recorded in the heating rate database for the first time, and to determine that the electrodes of the ohmic heating device are contaminated when the actual heating rate of the same type of food is 5% or more slower than the corresponding heating rate recorded in the heating rate database for three consecutive times, thus avoiding misjudgment and affecting the user experience.

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

[0073] In practice, the judgment result can be communicated to the user via a display screen, buzzer, or mobile app to inform them that the ohmic heating device should be cleaned, thereby extending the device's lifespan through timely cleaning and maintenance.

[0074] Furthermore, to facilitate cleaning of ohmic heating equipment, the characteristics of ohmic heating equipment can be utilized to clean it using glow discharge. This not only cleans the electrodes but also maintains the cleanliness of the equipment's interior. Compared to traditional physical cleaning methods, it can remove contaminants more thoroughly and requires less user intervention, reducing labor costs while improving the user experience.

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

[0076] In response to the user's electrode cleanliness self-check operation, the third heating rate corresponding to the ohmic heating device when heating water is determined, and the fourth heating rate corresponding to the water heating in the heating rate database is obtained;

[0077] Based on the third heating rate and the fourth heating rate, determine whether the ohmic heating device has electrode contamination.

[0078] If the electrode contamination is detected in the ohmic heating device, the user is notified to clean the ohmic heating device.

[0079] In practical implementation, a self-check function for the cleanliness of the ohmic heating device can also be provided to users. Specifically, before the device leaves the factory, water with a volume of 70% can be added to the food processing container of the ohmic heating device through experiments, and the device is heated to boiling using ohmic heating. The duration of this process is recorded in the heating rate database as benchmark data. When users want to use the cleanliness self-check function of the ohmic heating device, they can add water with a volume of 70% can be added to the food processing container of the ohmic heating device according to the markings on the device, and the device is heated to boiling using ohmic heating. The duration is recorded and compared with the benchmark data established in the heating rate database. This determines whether the electrodes are contaminated and whether the heating efficiency of the electrodes is affected. If the electrodes are determined to be contaminated, the result can be displayed on the screen, through a buzzer, or through a mobile app, informing the user to clean the ohmic heating device, thereby extending the device's lifespan through timely cleaning and maintenance.

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

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

[0082] In practical applications, the ohmic heating equipment can be pre-installed with a vacuum pump. When the user's electrode cleaning function is activated, the vacuum pump can be used to change the gas pressure inside the container to a pressure suitable for glow discharge. Generally, glow discharge can only be stable under low pressure. Therefore, when the cleaning work begins, the gas pressure inside the container can be adjusted to between 12 and 22 kPa to meet the glow discharge conditions.

[0083] Furthermore, once the air pressure meets the conditions for glow discharge, glow discharge treatment can be performed on the electrodes in the ohmic heating device. Specifically, the power supply of the ohmic heating device can be converted to AC, and the frequency and voltage of the power supply can be adjusted to the preset target range. Generally, the electric field condition of ohmic heating is DC, while the voltage is adjusted according to the different heating speeds required by different foods, usually at the daily electricity voltage or even lower. When glow discharge cleaning and disinfection are required, the power supply can be converted to AC, 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 in the previous cleaning steps can be removed by water rinsing to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water rinsing treatment can be carried out automatically by setting up the corresponding pipeline in advance, or the user can be notified that the glow discharge has been completed and the ohmic heating equipment needs to be rinsed with water.

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

[0086] The vacuum pump is used to adjust the air pressure of the ohmic heating device so that the internal conditions of the ohmic heating device meet the requirements for glow discharge.

[0087] In practice, the ohmic heating equipment can be pre-installed with a vacuum pump. When the user's electrode cleaning function is activated, the vacuum pump can be used to change the gas pressure inside the container to a pressure suitable for glow discharge. Generally, glow discharge can only be stable under low pressure. Therefore, when the cleaning work starts, the gas pressure inside 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 electrodes in the ohmic heating device includes:

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

[0090] In practical applications, once the air pressure meets the conditions for glow discharge, the electrodes in the ohmic heating device can be subjected to glow discharge treatment. Specifically, the power supply of the ohmic heating device can be converted to AC, and the frequency and voltage of the power supply can be adjusted to the preset target range. Generally, the electric field condition of ohmic heating is DC, while the voltage is adjusted according to the different heating speeds required by different foods, usually at the daily electricity voltage or even lower. When glow discharge cleaning and disinfection are required, the power supply can be converted to AC, 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 includes:

[0092] The user is instructed to flush the ohmic heating device with water.

[0093] In practice, after the glow discharge treatment is completed, the waste generated in the previous cleaning steps can be removed by water rinsing to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water rinsing treatment can be carried out automatically by setting up corresponding pipelines in advance, or the user can be notified that the glow discharge has been completed and the ohmic heating equipment needs to be rinsed with water. This ensures that there are no residual pollutants 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 The diagram illustrates a flowchart of another ohmic heating device control method provided by some embodiments of the present invention, which may specifically include the following steps:

[0095] Step 201: Obtain the first heating rate information set corresponding to the first heating of different types of food by the ohmic heating device and the second heating rate information set corresponding to different types of food in the network database; and determine the 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, the heating rate at which different types of food are heated to a preset temperature can be recorded when the ohmic heating device first heats them to obtain a first heating rate information set. The average heating rate of different types of food recorded in the network database can be obtained to obtain a second heating rate information set. Then, a heating rate database under normal operating conditions of the ohmic heating device can be established based on the first heating rate information set and / or the second heating rate information set, thereby improving the accuracy of subsequent judgment on electrode contamination status.

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

[0098] In practical implementation, the device can respond to the user's activation of the ohmic heating device and promptly identify the type of food placed inside. Specifically, this can be achieved by using a Raspberry Pi and a camera to first identify and train the device using a network database, and then building the user's own database during use. Through extensive training and iteration, the ohmic heating device can achieve high-precision identification of the same type of food.

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

[0100] In practical applications, when heating food with an ohmic heating device, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined, 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 steps, 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 whether the difference between the second heating rate and the first heating rate is greater than or equal to the 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, then determine that the ohmic heating device has electrode contamination.

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

[0103] In practice, the judgment result can be communicated to the user via a display screen, buzzer, or mobile app to inform them that the ohmic heating device should be cleaned, thereby extending the device's lifespan through timely cleaning and maintenance.

[0104] Furthermore, to facilitate cleaning of ohmic heating equipment, the characteristics of ohmic heating equipment can be utilized to clean it using glow discharge. This not only cleans the electrodes but also maintains the cleanliness of the equipment's interior. Compared to traditional physical cleaning methods, it can remove contaminants more thoroughly and requires less user intervention, reducing labor costs while improving the user experience.

[0105] Reference Figure 3 The diagram illustrates a flowchart of another ohmic heating device control method provided by some embodiments of the present invention, which may specifically include the following steps:

[0106] Step 301: Determine the heating rate database under normal operating conditions of the ohmic heating device;

[0107] In practical implementation, the heating rate database under normal operating conditions of the ohmic heating device can be determined first as a reference for 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 the heating rate database under normal operating conditions of the ohmic heating device.

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

[0109] In practical implementation, the device can respond to the user's activation of the ohmic heating device and promptly identify the type of food placed inside.

Through extensive training and iteration, the ohmic heating device can achieve high-precision identification of the same type of food.

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

[0111] In practical applications, when heating food with an ohmic heating device, the actual heating rate (i.e., the first heating rate) corresponding to the current food can be determined, 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 steps, for use in the subsequent electrode contamination phenomenon judgment process.

[0112] Step 304: Determine whether the ohmic heating device has electrode contamination based on the first heating rate and the second heating rate;

[0113] In specific implementation, it can be determined 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. 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 only possible to determine that the electrodes of the ohmic heating device are contaminated by a single judgment, but also when the actual heating rate of the same type of food 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, thus avoiding misjudgment and affecting the user experience.

[0114] To prevent contamination and avoid misjudgments that could negatively impact the user experience.

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

[0116] In practice, the judgment result can be communicated to the user via a display screen, buzzer, or mobile app to inform them that the ohmic heating device should be cleaned, thereby extending the device's lifespan through timely cleaning and maintenance.

[0117] Furthermore, to facilitate cleaning of ohmic heating equipment, the characteristics of ohmic heating equipment can be utilized to clean it using glow discharge. This not only cleans the electrodes but also maintains the cleanliness of the equipment's interior. Compared to traditional physical cleaning methods, it can remove contaminants more thoroughly and requires less user intervention, reducing labor costs while improving the user experience.

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

[0119] In practical applications, the ohmic heating equipment can be pre-installed with a vacuum pump. When the user's electrode cleaning function is activated, the vacuum pump can be used to change the gas pressure inside the container to a pressure suitable for glow discharge. Generally, glow discharge can only be stable under low pressure. Therefore, when the cleaning work begins, the gas pressure inside the container can be adjusted to between 12 and 22 kPa to meet the glow discharge conditions.

[0120] Furthermore, once the air pressure meets the conditions for glow discharge, glow discharge treatment can be performed on the electrodes in the ohmic heating device. Specifically, the power supply of the ohmic heating device can be converted to AC, and the frequency and voltage of the power supply can be adjusted to the preset target range. Generally, the electric field condition of ohmic heating is DC, while the voltage is adjusted according to the different heating speeds required by different foods, usually at the daily electricity voltage or even lower. When glow discharge cleaning and disinfection are required, the power supply can be converted to AC, 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 in the previous cleaning steps can be removed by water rinsing to ensure that the inside of the equipment is thoroughly cleaned. Specifically, the water rinsing treatment can be carried out automatically by setting up the corresponding pipeline in advance, or the user can be notified that the glow discharge has been completed and the ohmic heating equipment needs to be rinsed with water.

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

[0123] Reference Figure 4 The overall execution flow of the ohmic heating equipment control method provided by this invention can be summarized as follows: two processes: normal user start-up of the equipment and user start-up of the self-check function; and the temperature rise self-check standard of the equipment can be preset before leaving the factory before executing the above process.

[0124] Specifically, the normal user operation process for starting the device can include the following steps: Step 1, start the device; Step 2, record the heating rate of different foods; Step 3, determine whether the heating rate of the same type of food differs by 5% or more. If the heating rate of the same type of food differs by 5% or more, notify the user to clean up; if the heating rate of the same type of food does not differ by 5% or more, the cooking is completed normally; Step 4, turn off the device.

[0125] Furthermore, the user-initiated self-check process may include the following steps: Step 1, initiate self-check; Step 2, add 70% water and heat to boiling; Step 3, determine if the deviation from the set standard is 5% or more. If the deviation is 5% or more, notify the user to perform cleaning; if the deviation is not 5% or more, the user can directly shut down the device. Exemplary descriptions of the above steps have already been provided in the foregoing and will not be repeated here.

[0126] Furthermore, refer to Figure 5The overall process of glow discharge cleaning according to this invention can be summarized as follows: Step 1, activate the cleaning mode; Step 2, start the vacuum pump; Step 3, perform glow discharge cleaning; Step 4, rinse with water; Step 5, shut down. Similarly, exemplary descriptions of the above steps have been provided in the foregoing and will not be repeated here.

[0127] This invention provides a control method and device for an ohmic heating equipment, an electronic device, and a storage medium. Its basic working principle is to record the heating rate of similar foods. If the heating rate of the same type of food is 5% or more slower than the initially recorded or common heating rate for three consecutive times, the electrodes of the ohmic heating equipment can be determined to be contaminated and require cleaning. A second detection method, allowing user-selected detection, can be provided. In the design of the ohmic heating container, the time required to ohmically heat 70% of the container's capacity to boiling under new conditions can be pre-set based on experimental data, and this time can be set as a standard threshold. When the user selects to detect the electrodes, 70% of the container's capacity of water can be added again and ohmically heated to boiling. If the heating rate slows by 5%, it is determined to be contaminated and requires cleaning. If the detection result indicates contamination and the need for cleaning, a prompt to the user for electrode cleaning can be issued. If the user chooses to clean, a vacuum pump can be used to evacuate the equipment after the current use, and a glow discharge can be performed to clean the container and electrodes. Alternatively, if the user refuses, the user can choose a time to perform a glow discharge to clean the electrodes, thereby completing the monitoring and cleaning of the electrode contamination level.
