Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a control method for a heating device, a heating device, a storage medium, and an electronic device. Background Technology

[0002] The core temperature of heating devices is often difficult to detect directly. For example, in an oven, the core temperature is the temperature at the center of the oven. Because it is difficult to install a temperature sensor at the center of the oven, it is difficult to accurately control the temperature at the center of the oven.

[0003] To address the aforementioned issues, the relevant heating devices utilize temperature sensors to detect the temperature at non-core locations. They then adjust the on / off ratio based on the mapping relationship between the preset temperature at the non-core location and the target temperature at the core location to achieve temperature control.

[0004] However, the existing temperature control methods for heating devices are easily affected by environmental factors, leading to inaccurate temperature control. Summary of the Invention

[0005] The main technical problem addressed in this application is how to improve the temperature control accuracy of heating devices.

[0006] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a control method for a heating device, wherein the heating device has a set first position and a second position, and the control method for the heating device includes:

[0007] Obtain the first target temperature, preset parameters, and actual power at the first location;

[0008] The reference on / off ratio and the second target temperature at the second position are obtained based on preset parameters and actual power.

[0009] Detect the actual temperature at the second location;

[0010] Calculate the temperature deviation between the actual temperature and the second target temperature;

[0011] The actual on / off ratio is controlled based on the mapping relationship between temperature deviation and reference on / off ratio.

[0012] The preset parameters include calibrated power, first preset temperature and first preset on / off ratio, and the first preset temperature and first preset on / off ratio have a mapping relationship with the first target temperature under calibrated power.

[0013] Based on preset parameters and actual power, the reference on / off ratio and the second target temperature at the second position are obtained, including:

[0014] Calculate the power deviation between the rated power and the actual power;

[0015] Determine whether the power deviation is within the preset range;

[0016] If so, the second target temperature is the first preset temperature, and the reference on / off ratio is the first preset on / off ratio;

[0017] If not, the corrected temperature and corrected on / off ratio are calculated based on preset parameters and actual power. The corrected temperature and corrected on / off ratio have a mapping relationship with the first target temperature under actual power. The second target temperature is the corrected temperature, and the reference on / off ratio is the corrected on / off ratio.

[0018] If the power deviation is within a preset range, the control method for the heating device also includes:

[0019] Generate the first preset information;

[0020] If the power deviation is outside the preset range, the control method for the heating device also includes:

[0021] Generate a second preset message.

[0022] The preset parameters include maximum power, second preset temperature and second preset on / off ratio, and the second preset temperature and second preset on / off ratio have a mapping relationship with the first target temperature at maximum power.

[0023] The corrected temperature and corrected on / off ratio are calculated based on preset parameters and actual power, including:

[0024] Calculate the power difference between the maximum power and the rated power;

[0025] Calculate the temperature difference between the second preset temperature and the first preset temperature;

[0026] Calculate the difference between the second preset on / off ratio and the first preset on / off ratio;

[0027] The corrected temperature and corrected on / off ratio are calculated by combining the power deviation, power difference, temperature difference, and on / off ratio difference.

[0028] The difference between the corrected temperature and the first preset temperature is the first correction value. The first correction value is directly proportional to the power deviation, inversely proportional to the power difference, and directly proportional to the temperature difference.

[0029] The difference between the corrected on / off ratio and the first preset on / off ratio is the second correction value. The second correction value is directly proportional to the power deviation, inversely proportional to the power difference, and directly proportional to the difference in on / off ratio.

[0030] Among them, controlling the actual on / off ratio based on the mapping relationship between temperature deviation and reference on / off ratio includes:

[0031] The target on / off ratio is obtained based on temperature deviation and reference on / off ratio;

[0032] Adjust the actual on / off ratio according to the target on / off ratio.

[0033] The process of obtaining the target on / off ratio based on temperature deviation and a reference on / off ratio includes:

[0034] If the temperature deviation is within the first deviation range, the target on / off ratio is greater than the reference on / off ratio.

[0035] If the temperature deviation is within the second deviation range, then the target on / off ratio is equal to the reference on / off ratio;

[0036] If the temperature deviation is within the third deviation range, the target on / off ratio is less than the reference on / off ratio;

[0037] Among them, the first deviation range is smaller than the second deviation range, and the second deviation range is smaller than the third deviation range.

[0038] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a heating device having a set first position and a second position, the heating device comprising:

[0039] The input module is used to obtain the first target temperature at the first location;

[0040] A power detection module is used to obtain the actual power.

[0041] The temperature detection module is used to detect the actual temperature at the second location;

[0042] The control module is used to acquire preset parameters, and based on the preset parameters and actual power, obtain the second target temperature and reference on / off ratio of the second position, and control the actual on / off ratio based on the temperature deviation between the actual temperature and the second target temperature and the mapping relationship between the reference on / off ratio.

[0043] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide a computer-readable storage medium storing program data, which can be executed by a processor to implement the above-mentioned control method of the heating device.

[0044] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an electronic device, including a memory and a processor coupled together, wherein the memory stores program data and the processor executes the program data to realize the above-mentioned control method of the heating device.

[0045] The advantages of the control method, heating device, storage medium, and electronic equipment provided in this application, which differ from existing technologies, are as follows:

[0046] This application obtains a reference on / off ratio and a second target temperature based on actual power and preset parameters, and controls the actual on / off ratio based on the mapping relationship between the temperature deviation between the actual temperature and the second target temperature and the reference on / off ratio, so as to achieve temperature control of the heating device, effectively improving the temperature control accuracy of the heating device and improving the user experience.

[0059] This application first proposes a control method for a heating device. Please refer to [link / reference needed]. Figure 1 , Figure 1 This is a schematic flowchart of an embodiment of the control method for the heating device provided in this application.

[0060] In this embodiment, the control method of the heating device includes:

[0061] S11, Obtain the first target temperature at the first position.

[0062] The first position is a position set by the heating device. The first target temperature is a target temperature to be achieved at the first position. The first position can be the location inside the heating device primarily used to hold the object to be heated. The first target temperature can be the temperature to be reached when heating the object.

[0063] In one embodiment, the heating device can be an oven. A heating cavity is formed inside the oven. For example, the first position of the oven is the center position of the heating cavity, and the first target temperature is the oven's set temperature, i.e., the temperature selected or input by the user. The center of the heating cavity is the location in the oven primarily used for heating food or other items awaiting heating, and the first target temperature is the temperature to be achieved at the center of the heating cavity.

[0064] In other embodiments, the heating device may also be other heatable devices such as a microwave oven or an air fryer. The first position may also be set to other positions of the heating device.

[0065] In one application scenario, when the heating device is activated, the module within the device can obtain the first target temperature at the first location. This first target temperature can be user-inputted, such as when a user selects a start button corresponding to a specific target temperature, thereby controlling the heating device to start and heat to that temperature. Alternatively, the first target temperature can be a pre-set temperature value for the heating device; for example, the heating device may default to setting the target temperature at the first location after activation.

[0066] In one application scenario, the heating device is either in operation or standby mode. The heating device can acquire a first target temperature at a first location. This first target temperature can be user-inputted; for example, the user sets a specific heating temperature after activating the heating device, and this temperature becomes the first target temperature at the first location. Alternatively, the user can adjust the heating temperature during operation, and the adjusted temperature becomes the first target temperature at the first location. The first target temperature can also be automatically adjusted by the heating device; for example, the heating device may be set to adjust the heating temperature to a preset temperature at a specific time or under a specific scenario, and this preset temperature becomes the first target temperature at the first location.

[0067] S12, Obtain preset parameters.

[0068] After the heating device obtains the first target temperature at the first location, it can acquire several preset parameters. The preset parameters may differ for different first target temperatures. When the first target temperature at the first location changes, the preset parameters acquired by the heating device may also change accordingly.

[0069] In one embodiment, the preset parameters obtained by the heating device include preset power, preset temperature, and preset on / off ratio.

[0070] The preset power is the heating power calibrated offline by the heating device and does not change with the first target temperature. The preset power includes the rated power, maximum power, and minimum power. The rated power is the standard set heating power of the heating device during operation. The maximum power is the maximum power required for the heating device to operate normally. That is, if the heating power of the heating device exceeds the maximum power, the heating element may burn out, leading to malfunction. The minimum power is the minimum power required for the heating device to operate normally. That is, if the heating power of the heating device is less than the minimum power, the heating temperature may be too low or even lose control, resulting in malfunction.

[0071] The preset temperature is a reference temperature value for the heating device at its second position. The second position is a location set by the heating device that differs from the first position. Since the first position is often inconvenient for direct temperature measurement, a temperature sensor is installed at the second position to detect the temperature there. The temperature at the first position is then calculated using the mapping relationship between the temperatures at the first and second positions. In other words, the second position is the location of the heating device where the temperature sensor is installed. For example, in an oven, the first position is the center of the heating cavity, and the second position is the oven wall, with the temperature sensor mounted on the wall. The temperatures at the first and second positions have a fixed mapping relationship under a fixed power. Therefore, the heating device has a preset temperature corresponding to the first target temperature at a preset power. When the second position of the heating device reaches the preset temperature under the preset power, it is considered that the first position has reached the first target temperature.

[0072] The preset temperatures can be divided into a first preset temperature, a second preset temperature, and a third preset temperature. The first preset temperature is the temperature value at the second position under calibrated power that maps to the first target temperature at the first position. The second preset temperature is the temperature value at the second position under maximum power that maps to the first target temperature at the first position. The third preset temperature is the temperature value at the second position under minimum power that maps to the first target temperature at the first position.

[0073] The preset on / off ratio is the on / off ratio of the heating device at a preset power level that maps to the first target temperature and the preset temperature. The on / off ratio refers to the ratio of the on-time to the off-time within one working cycle. The heating device controls the temperature by adjusting this time ratio. The preset on / off ratio can be divided into a first preset on / off ratio, a second preset on / off ratio, and a third preset on / off ratio. The first preset on / off ratio is the on / off ratio of the heating device at its rated power level that maps to the first target temperature at the first position. The second preset on / off ratio is the on / off ratio of the heating device at its maximum power level that maps to the first target temperature at the first position. The third preset on / off ratio is the on / off ratio of the heating device at its minimum power level that maps to the first target temperature at the first position.

[0074] Furthermore, in some embodiments, the preset power is not limited to the rated power, maximum power, and minimum power, and may be other powers. The preset temperature and preset on / off ratio are the temperature value and on / off time ratio that map to the first target temperature at the first position under the corresponding power.

[0075] In another embodiment, the preset parameters acquired by the heating device include multiple mapping tables. There is a mapping relationship between the preset temperature, the first target temperature, and the preset on / off ratio, and multiple sets of mapping data form a single mapping table. For example, at a certain heating power, the preset temperature is matrix {0, 150, 230}, the first target temperature is matrix {0, 130, 220}, and the preset on / off ratio is matrix {0, 10, 15}. Specifically, the first set of mapping data is: preset temperature 0, first target temperature 0, preset on / off ratio 0; the second set of mapping data is: preset temperature 150 degrees Celsius, first target temperature 130 degrees Celsius, preset on / off ratio 10; and the third set of mapping data is: preset temperature 230 degrees Celsius, first target temperature 220 degrees Celsius, preset on / off ratio 15.

[0076] In other words, at this heating power, if the target temperature at the first position is 0 degrees Celsius, the heating device will set the on / off ratio to 0 and fine-tune the on / off ratio to control the temperature at the second position to 0 degrees Celsius. At this time, the temperature at the first position is considered to have been adjusted to 0 degrees Celsius. If the target temperature at the first position is 130 degrees Celsius, the heating device will set the on / off ratio to 10 and fine-tune the on / off ratio to control the temperature at the second position to 150 degrees Celsius. At this time, the temperature at the first position is considered to have been adjusted to 130 degrees Celsius. If the target temperature at the first position is 220 degrees Celsius, the heating device will set the on / off ratio to 15 and fine-tune the on / off ratio to control the temperature at the second position to 230 degrees Celsius. At this time, the temperature at the first position is considered to have been adjusted to 220 degrees Celsius.

[0077] When the heating device fine-tunes the on / off ratio to control the temperature of the second position, it can directly adjust the on / off ratio to a preset on / off ratio, or adjust the on / off ratio to be greater than or less than the preset on / off ratio according to the deviation between the actual temperature of the second position and the preset temperature, so as to increase the rate at which the actual temperature of the second position changes to the preset temperature, and control the actual on / off ratio to reach the preset on / off ratio when the actual temperature of the second position reaches the preset temperature.

[0078] The number of mapping data points included in the mapping table is not specifically limited. Multiple mapping tables for different heating powers can be obtained through repeated experiments. All heating powers are greater than or equal to the minimum power and less than or equal to the maximum power.

[0079] S13, Obtain the actual power.

[0080] The actual power refers to the actual heat output of the heating device during operation. This actual power can be obtained through a real-time power detection module. In some applications, the actual power of the heating device cannot be consistently maintained at the preset power, resulting in lower temperature control accuracy.

[0081] S14. Based on preset parameters and actual power, obtain the reference on / off ratio and the second target temperature at the second position.

[0082] Since the mapping relationship between the temperature at the first position, the temperature at the second position, and the on / off ratio changes with the heating power, when the heating power of the heating device is inaccurate, the temperature control that relies on the mapping relationship between the temperature at the first position, the temperature at the second position, and the on / off ratio under the preset power will also be inaccurate.

[0083] To address this technical problem, this application obtains a reference on / off ratio and a second target temperature at a second position based on preset parameters and actual power. In other words, this application does not rely on a preset temperature and preset on / off ratio at a preset power to control the temperature, but rather relies on a reference on / off ratio obtained by combining the real-time detected actual power and the second target temperature at the second position to control the temperature, thereby improving the accuracy of temperature control.

[0084] Optionally, the preset parameters include rated power, maximum power, a first preset temperature, a second preset temperature, a first preset on / off ratio, and a second preset on / off ratio. Please refer to the following references. Figure 2 , Figure 2 This application Figure 1 A schematic diagram of the specific process of step S14.

[0085] Step S14 includes the following methods:

[0086] S21. Calculate the power deviation between the rated power and the actual power.

[0087] The rated power is the standard heating power of the heating device when it is working. However, in some application scenarios, the heating device cannot stably heat at the rated power due to the influence of environmental factors, and there is a power deviation between the actual power and the rated power.

[0088] For example, in some remote mountainous areas, the voltage of heating devices is often unstable, causing deviations in the actual power of the heating device, resulting in the actual power being either too high or too low. When this deviation is large, cooking will be greatly affected. For instance, if an oven's rated power is 2300W but the actual power is only 2000W, the power deviation between the actual power and the rated power reaches -300W, and the food is likely to be undercooked; or, if an oven's rated power is 2300W but the actual power reaches 2500W, the power deviation between the actual power and the rated power reaches 200W, and the food is likely to burn.

[0089] For example, some users plug their ovens into power strips. If the power strip has a low maximum current rating, the oven's actual power output may not reach its rated power. For instance, if an oven is plugged into a power strip with a maximum current rating of 10A, its rated power is 2300W, but its actual power output may only reach 2100W. This power deviation of -200W can lead to insufficient heating and pose a safety hazard.

[0090] In other words, the heating power of a heating device is easily affected by factors related to voltage and current, leading to deviations in the actual power. These deviations may be greater than 0, less than 0, or fluctuate between 0 and 0.

[0091] S22. Determine whether the power deviation is within the preset range.

[0092] If the deviation between the actual power and the rated power is small, the interference with the temperature control of the heating device will be minimal. However, if the deviation is too large, it will significantly impact the temperature control of the heating device. In some embodiments, the preset range is an allowable power deviation range. That is, when the power deviation is small, its impact can be ignored to improve efficiency; when the power deviation is large, algorithmic compensation based on the relationship between the actual power and the rated power is required to fine-tune the temperature and achieve higher temperature control accuracy.

[0093] Optionally, the preset range includes rated power multiplied by -5% to rated power multiplied by 5%. The preset range includes -5%, -4%, -3%, -2%, -1%, 0, 1%, 2%, 3%, 4%, 5% of the rated power.

[0094] Of course, in some embodiments, the preset range can also be adjusted according to the actual situation, such as expanding or shrinking the preset range.

[0095] If the power deviation is within the preset range, proceed to step S23.

[0096] S23. The second target temperature is the first preset temperature, and the reference on / off ratio is the first preset on / off ratio.

[0097] When the power deviation is within the preset range, i.e., the actual power is greater than or equal to 0.95 times the rated power and less than or equal to 1.05 times the rated power, the power deviation is small and no compensation is required. At this time, the heating device uses the first preset temperature as the second target temperature and the first preset on / off ratio as the reference on / off ratio to achieve temperature control.

[0098] If the power deviation is not within the preset range, proceed to step S24.

[0099] S24. Based on preset parameters and actual power, calculate the corrected temperature and corrected on / off ratio. The second target temperature is the corrected temperature, and the reference on / off ratio is the corrected on / off ratio.

[0100] Two compensation baselines are established: rated power multiplied by -5% and rated power multiplied by 5%. When the power deviation is outside the preset range (i.e., the actual power is less than 0.95 times the rated power or greater than 1.05 times the rated power), the heating device enters compensation mode. In this mode, the heating device calculates the corrected temperature and corrected on / off ratio based on preset parameters and the actual power. The corrected temperature is used as the second target temperature, and the corrected on / off ratio is used as the reference on / off ratio to achieve temperature control. The corrected temperature and corrected on / off ratio have a mapping relationship with the first target temperature at the first position under the actual power.

[0101] In one embodiment, the calculation process for the corrected temperature and the corrected on / off ratio includes:

[0102] Calculate the power difference between the maximum power and the rated power. In other words, if the maximum power is P0max and the rated power is P0, the power difference is P0max - P0.

[0103] Calculate the temperature difference between the second preset temperature and the first preset temperature. In other words, if the first preset temperature is T1 and the second preset temperature is T2, the temperature difference is T2 - T1.

[0104] Calculate the difference between the second preset on / off ratio and the first preset on / off ratio. In other words, if the first preset on / off ratio is PWM1 and the second preset on / off ratio is PWM2, the difference between the on / off ratios is PWM2 - PWM1.

[0105] Furthermore, the power deviation is the difference between the actual power and the rated power. That is to say, if the actual power is P' and the rated power is P0, the power deviation is P' - P0.

[0106] By combining the power deviation, power difference, temperature difference, and on / off ratio difference, the corrected temperature and corrected on / off ratio can be calculated.

[0107] The difference between the corrected temperature and the first preset temperature is the first correction value. In other words, the corrected temperature is obtained by adding the first correction value to the first preset temperature. The first correction value is directly proportional to the power deviation. The first correction value is inversely proportional to the power difference. The first correction value is directly proportional to the temperature difference.

[0108] The difference between the corrected on / off ratio and the first preset on / off ratio is the second correction value. In other words, the corrected on / off ratio is obtained by adding the second correction value to the first preset on / off ratio. The second correction value is directly proportional to the power deviation. The second correction value is inversely proportional to the power difference. The second correction value is directly proportional to the difference in on / off ratios.

[0109] The specific formula for calculating the corrected temperature T' is as follows:

[0110] T'=(P1-P0) / (P0max-P0)*(T2-T1)+T1.

[0111] The specific calculation formula for the corrected on / off ratio PWM' is as follows:

[0112] PWM'=(P1-P0) / (P0MAX-P0)*(PWM2-PWM1)+PWM1.

[0113] Of course, the specific calculation process for correcting the temperature and correcting the on / off ratio is not limited to this embodiment.

[0114] In addition, preset parameters may also include rated power, minimum power, first preset temperature, third preset temperature, first preset on / off ratio, and third preset on / off ratio. The correction temperature and correction on / off ratio are calculated based on the actual power and preset parameters. The specific calculation process will not be elaborated here.

[0115] In other embodiments, the corrected temperature and corrected on / off ratio can also be calculated in other ways. For example, the preset parameters include multiple mapping tables for different heating powers, each mapping table including multiple sets of mapping data, and each set of mapping data including a temperature at a first position, a temperature at a second position, and an on / off ratio that have a mapping relationship.

[0116] Each mapping table corresponds to a specific heating power. After detecting the actual power, the deviation between the actual power and the preset power is calculated, and a mapping table for the corresponding actual power is obtained based on the correspondence between the heating power and the mapping table. Furthermore, the temperature and on / off ratio at the second position corresponding to the first target temperature are found from the mapping table for the corresponding actual power, serving as the correction temperature and correction on / off ratio. The specific calculation process is not elaborated here.

[0117] In some implementations, the heating device may not need to determine the magnitude of the power deviation. When a power deviation exists, the corrected temperature and corrected on / off ratio are directly calculated, and the obtained corrected temperature is used as the second target temperature, and the obtained corrected on / off ratio is used as the reference on / off ratio.

[0118] Optionally, the heating device can also generate preset information based on the magnitude of the power deviation.

[0119] If the power deviation is within a preset range, a first preset message is generated. This first preset message may include information indicating a small power deviation and is transmitted externally via a display panel, speaker, etc., to alert the user. For example, the heating device may display messages such as "Power normal" or "Small power deviation," or it may emit a specific prompt tone. Alternatively, the first preset message may not be transmitted externally.

[0120] If the power deviation is outside the preset range, a second preset message is generated. This second preset message includes information such as whether the power is too high or too low, and is transmitted to the outside via a display panel, speaker, etc., to alert the user. For example, when the actual power is less than the rated power, the heating device can display "Power too low, compensating in progress," so that the user is aware that the heating power is insufficient, but the temperature can still be controlled at the set target temperature. The heating device can also indicate the specific cause of the power deviation, such as "unstable voltage" or "limited current too low," so that the user knows the cause of the power deviation and can easily eliminate potential problems. The second preset message can be transmitted to the outside through light, sound, or other perceptible media.

[0121] S15, Detect the actual temperature at the second location.

[0122] The heating device uses a temperature sensor to detect the actual temperature at the second position in real time, so as to reflect the actual temperature at the first position. Thus, the heating device can control the actual temperature at the first position based on the actual temperature change at the second position.

[0123] Since the temperature distribution may be uneven, multiple second locations can be set, that is, temperature sensors can be installed at multiple locations to improve the accuracy of temperature control.

[0124] S16. Calculate the temperature deviation between the actual temperature at the second location and the second target temperature.

[0125] The second target temperature is the target temperature that the heating device aims to achieve at the second position. By calculating the temperature deviation between the actual temperature at the second position and the second target temperature, the temperature can be further controlled based on this temperature deviation.

[0126] S17. Control the actual on / off ratio based on the mapping relationship between temperature deviation and reference on / off ratio.

[0127] In one embodiment, the heating device adjusts the actual on / off ratio to be equal to a reference on / off ratio. The reference on / off ratio is an on / off time ratio mapped to a second target temperature. By adjusting the actual on / off ratio to the reference on / off ratio, the temperature deviation can be gradually reduced. For example, when the actual temperature at the second position is lower than the second target temperature, the actual on / off ratio is less than the reference on / off ratio. In this case, adjusting the actual on / off ratio to the reference on / off ratio is equivalent to extending the heating time in each cycle, thereby allowing the actual temperature at the second position to gradually rise to the second target temperature. Similarly, when the actual temperature at the second position is higher than the second target temperature, the actual on / off ratio is greater than the reference on / off ratio. Likewise, adjusting the actual on / off ratio to the reference on / off ratio allows the actual temperature at the second position to gradually decrease to the second target temperature.

[0128] In another embodiment, the heating device obtains another reference value for controlling the actual on / off ratio based on the mapping relationship between the temperature deviation and the reference on / off ratio. Please refer to [reference needed]. Figure 3 , Figure 3 yes Figure 1 A schematic diagram of the specific process of step S17.

[0129] Step S17 includes the following methods:

[0130] S31. Obtain the target on / off ratio based on temperature deviation and reference on / off ratio.

[0131] S32. Adjust the actual on / off ratio according to the target on / off ratio.

[0132] The target on / off ratio is a reference value obtained based on the temperature deviation and the reference on / off ratio. The target on / off ratio can be greater than, less than, or lower than the reference on / off ratio. The actual on / off ratio is further adjusted according to the target on / off ratio, allowing the heating device to adjust the actual on / off ratio based on changes in actual power, thus achieving precise temperature control. Specifically, the heating device can adjust the actual on / off ratio for the next cycle to the target on / off ratio after obtaining the target on / off ratio, or adjust the actual on / off ratio after a preset number of cycles to the target on / off ratio. Of course, the heating device can also adjust the actual on / off ratio to a suitable on / off ratio value other than the target on / off ratio value; this is not specifically limited here.

[0133] Optionally, the heating device is pre-set with a first deviation range, a second deviation range, and a third deviation range corresponding to the temperature deviation. The first deviation range is smaller than the second deviation range, and the second deviation range is smaller than the third deviation range.

[0134] If the temperature deviation is within the first deviation range, the target on / off ratio is greater than the reference on / off ratio. The first deviation range is defined as the range where the actual temperature at the second position is lower than the second target temperature and the temperature deviation is significant. In other words, when the temperature deviation falls within the first deviation range, it means that the actual temperature at the second position is much lower than the second target temperature. In this case, by adjusting the actual on / off ratio to a target on / off ratio greater than the reference on / off ratio, the heating time within each cycle can be extended, allowing the actual temperature at the second position to rise rapidly.

[0135] If the temperature deviation is within the second deviation range, the target on / off ratio equals the reference on / off ratio. The second deviation range refers to the range where the temperature deviation is relatively small. In other words, when the temperature deviation falls within the second deviation range, it means that there is no deviation or a small deviation between the actual temperature at the second location and the second target temperature; that is, the actual temperature at the second location is slightly less than, slightly greater than, or equal to the second target temperature. In this case, by adjusting the actual on / off ratio to the target on / off ratio equal to the reference on / off ratio, if the actual temperature at the second location is slightly less than the second target temperature, the actual temperature at the second location can gradually rise to the second target temperature; if the actual temperature at the second location is slightly greater than the second target temperature, the actual temperature at the second location can gradually decrease to the second target temperature; and if the actual temperature at the second location equals the second target temperature, the actual temperature at the second location can be maintained at the second target temperature.

[0136] If the temperature deviation falls within the third deviation range, the target on / off ratio is less than the reference on / off ratio. The third deviation range refers to the area where the actual temperature at position two is greater than the second target temperature and the temperature deviation is significant. In other words, when the temperature deviation falls within the third deviation range, it means that the actual temperature at position two is much greater than the second target temperature. In this case, by adjusting the actual on / off ratio to a target on / off ratio that is less than the reference on / off ratio, the heating time in each cycle can be shortened, allowing the actual temperature at position two to drop rapidly.

[0137] The temperature deviation will change with the actual temperature at the second position, and the target on / off ratio will be adjusted accordingly.

[0138] For example, when the temperature deviation is within the first deviation range, the heating device controls the actual on / off ratio to be equal to a target on / off ratio greater than the reference on / off ratio, so that the actual temperature at the second position can rise rapidly. As the actual temperature at the second position rises, the temperature deviation gradually decreases. When the temperature deviation enters the second deviation range, the heating device controls the actual on / off ratio to be equal to a target on / off ratio equal to the reference on / off ratio, thereby slowing down the rate of temperature rise at the second position until the actual temperature at the second position equals the second target temperature, and then stabilizes at the second target temperature. The specific value of the target on / off ratio can be set according to actual conditions and is not specifically limited here.

[0139] For example, when the temperature deviation is within the third deviation range, the heating device controls the actual on / off ratio to be equal to the target on / off ratio, which is less than the reference on / off ratio, so that the actual temperature at the second position can drop rapidly. As the actual temperature at the second position decreases, the temperature deviation also gradually decreases. When the temperature deviation enters the second deviation range, the heating device controls the actual on / off ratio to be equal to the target on / off ratio, which is equal to the reference on / off ratio, thereby slowing down the rate of temperature drop at the second position until the actual temperature at the second position equals the second target temperature, and then stabilizes at the second target temperature. The specific value of the target on / off ratio can be set according to actual conditions and is not specifically limited here.

[0140] Optionally, the first deviation range includes multiple first sub-deviation ranges, each corresponding to a target on / off ratio, with the target on / off ratio increasing the further away the first sub-deviation range is from the second deviation range. The third deviation range includes multiple second sub-deviation ranges, each corresponding to a target on / off ratio, with the target on / off ratio decreasing the further away the second sub-deviation range is from the second deviation range. Through this design, when the heating device controls the actual on / off ratio to be equal to the target on / off ratio, a larger temperature deviation results in a faster rate at which the actual temperature at the second position approaches the second target temperature, effectively improving the efficiency of temperature control.

[0141] Furthermore, when the actual power of the heating device changes, the second target temperature and the reference on / off ratio will also change accordingly. At this time, the heating device can re-obtain the target on / off ratio based on the temperature deviation and the reference on / off ratio, and adjust the actual on / off ratio according to the new target on / off ratio, so that the heating device can still accurately control the temperature when the power is unstable.
