Description

Technical Field

[0001] The present invention relates to the technical field of cooking appliances, and in particular to a cooking appliance control method and the cooking appliance. Background Art

[0002] Existing induction cookers generally include a temperature control function, that is, a temperature sensor is provided on the induction cooker to sense the temperature of the bottom of the pot or the stove panel. When the temperature is higher than the set value, the heating power will be actively reduced until the temperature of the bottom of the pot or the stove panel can be maintained at an appropriate and relatively stable state, thereby playing a high temperature prevention and control effect on the pot and ensuring the cooking temperature.

[0003] As for the case where the infrared stove plate and the electromagnetic wire coil are combined to form a new hybrid heating cooking utensil, there is a situation where the user turns on the electromagnetic heating function after using the infrared heating function. At this time, the temperature of the infrared stove plate and the stove panel can reach a maximum of about 600 degrees Celsius, and the sensor used to detect the temperature of the bottom of the pot or the stove panel is also in a high temperature state, exceeding the temperature control threshold of a general induction cooker. According to the program setting of a general induction cooker, when the user starts the electromagnetic heating function of the cooking utensil, since the temperature sensor is in a high temperature state, the cooking utensil will judge that the pot is in a high temperature state, and enter low-power heating, or stop heating, thereby failing to achieve the user's purpose of continuing to use the electromagnetic heating function, or the user needs to wait for the temperature of the infrared stove plate and the stove panel to drop before starting the electromagnetic heating function again, and the time it takes for the infrared stove plate and the stove panel to naturally cool down is very long, resulting in a long waiting time and poor practicality.

[0065] Existing induction cookers generally include a temperature control function, that is, a temperature sensor is provided on the induction cooker to sense the temperature of the bottom of the pot or the stove panel. When the temperature is higher than the set value, the heating power will be actively reduced until the temperature of the bottom of the pot or the stove panel can be maintained at an appropriate and relatively stable state, thereby playing a high temperature prevention and control effect on the pot and ensuring the cooking temperature.

[0066] As for the case where the infrared stove plate and the electromagnetic wire coil are combined to form a new hybrid heating cooking utensil, there is a situation where the user turns on the electromagnetic heating function after using the infrared heating function. At this time, the temperature of the infrared stove plate and the stove panel can reach a maximum of about 600 degrees Celsius, and the sensor used to detect the temperature of the bottom of the pot or the stove panel is also in a high temperature state, exceeding the temperature control threshold of a general induction cooker. According to the program setting of a general induction cooker, when the user starts the electromagnetic heating function of the cooking utensil, since the temperature sensor is in a high temperature state, the cooking utensil will judge that the pot is in a high temperature state, and enter low-power heating, or stop heating, thereby failing to achieve the user's purpose of continuing to use the electromagnetic heating function, or the user needs to wait for the temperature of the infrared stove plate and the stove panel to drop before starting the electromagnetic heating function again, and the time it takes for the infrared stove plate and the stove panel to naturally cool down is very long, resulting in a long waiting time and poor practicality.

[0067] In view of this, the present invention provides a control method for a cooking appliance. Figures 1 to 7 This is an embodiment of the control method of the cooking appliance provided by the present invention, and the control method of the cooking appliance will be described below in conjunction with specific drawings.

[0068] See also Figures 1 to 7 The cooking appliance 100 includes an infrared heating component 31 and an electromagnetic heating component 32 corresponding to the same heating area 21, and the control method of the cooking appliance 100 includes the following steps:

[0069] S100: After the infrared heating mode ends and the electromagnetic heating mode is entered, the working parameters of the infrared heating component 31 are obtained;

[0070] S200: Acquire temperature control parameters of a corresponding electromagnetic heating mode according to the working parameters;

[0071] S300: Controlling the electromagnetic heating component 32 to operate according to the temperature control parameters.

[0072] In the technical solution of the present invention, for the cooking appliance 100 having both the infrared heating component 31 and the electromagnetic heating component 32, when entering the electromagnetic heating mode after the infrared heating mode ends, in order to avoid the above-mentioned stove panel 2 or temperature sensor 5 being in a high temperature state, which results in the restriction of the normal opening of the electromagnetic heating component 32 according to the conventional temperature control program, the temperature control parameters of the electromagnetic heating mode of the cooking appliance 100 need to be changed to obtain the corresponding unconventional temperature control parameters under the high temperature state. However, at the same time, the cooking appliance 100 also has the situation that it does not use infrared heating but only uses electromagnetic heating, or the infrared heating mode is used for a light degree of heating, or the infrared heating mode is used for a long cooling time. When the electromagnetic heating is turned on, it is essentially the same as the environment for electromagnetic heating of the ordinary electromagnetic cooking appliance 100. At this time, the electromagnetic heating mode needs to use the temperature control parameters of the conventional electromagnetic heating mode to ensure the cooking temperature, so the cooking appliance 100 also needs to retain the conventional temperature control parameters of the electromagnetic heating mode. Based on this, the present application mainly proposes a control method for selecting the temperature control parameters of the electromagnetic heating mode according to the working parameters of the infrared heating component 31 after the infrared heating mode ends, so as to meet the temperature control requirements of the electromagnetic heating component 32 of the cooking utensil 100 under different usage scenarios, so as to meet the cooking needs of the user.

[0073] Specifically, the main scenarios targeted by this application include the situation where, after using the infrared heating mode to heat a casserole or the like for making soup, it is necessary to switch the pot 200 to use the electromagnetic heating mode for quick frying in an iron pan. In this case, when the electromagnetic heating mode is turned on, the temperature of the stove panel 2 or the temperature sensor 5 is too high. At this time, if the conventional temperature control parameters of the electromagnetic cooking utensil 100 are used, the cooking utensil 100 will be greatly restricted to the electromagnetic heating mode according to the conventional temperature control parameters, affecting the normal activation of the electromagnetic heating mode and causing inconvenience in use. In addition, this application is also applicable to other situations where the electromagnetic heating mode needs to be used immediately after the infrared heating mode is used, which will not be listed one by one here.

[0074] Specifically, the step S200 includes:

[0075] S210: Determine whether it is necessary to adjust the pre-stored temperature control parameters according to the working parameters;

[0076] S220: Determine the temperature control parameters of the corresponding electromagnetic heating mode according to the judgment result.

[0077] The temperature control parameters of the corresponding electromagnetic heating mode can be selected by pre-storing multiple sets of temperature control parameters to correspond to different working parameters of the infrared heating component 31, and then to different usage scenarios of the electromagnetic heating component 32. However, it is obvious that setting multiple sets of temperature control parameters requires increasing the storage space of the control device 4 in the cooking appliance 100, and the control logic of multiple sets of temperature control parameters can essentially remain consistent in the actual application environment of the present application, and only the values ​​need to be adjusted. Therefore, in the present application, only one set of temperature control parameters is pre-stored, and this set of temperature control parameters can be directly set to the conventional temperature control parameters of the above-mentioned electromagnetic cooking appliance 100 to reduce the number of control parameters stored, and the conventional temperature control parameters are used to eliminate the need for additional temperature control parameter design of the cooking appliance 100, thereby reducing design costs. Furthermore, according to the preset judgment criteria, when it is determined that the pre-stored temperature control parameters under the working parameters cannot meet the usage requirements, it is only necessary to adjust the pre-stored temperature control parameters through a certain adjustment logic to form adjusted temperature control parameters, which correspond to the obtained working parameters of the infrared heating component 31 and meet the usage requirements of the cooking appliance 100, so as to simplify the design method of different temperature control parameters and further reduce the design cost of the control logic.

[0078] Specifically, in an embodiment of the control method of the cooking appliance 100, the working parameter includes the temperature value of the heating area 21, and the step S210 includes:

[0079] S211: Compare the temperature value T1 of the heating area 21 with the preset temperature value T0;

[0080] S212: If T1<T0, the pre-stored temperature control parameters are used as the temperature control parameters of the electromagnetic heating mode;

[0081] S213: If T1 ≥ T0, the pre-stored temperature control parameters are adjusted, and the adjusted temperature control parameters are used as the temperature control parameters of the electromagnetic heating mode.

[0082] Intuitively, the working parameter may be the temperature value of the heating area 21, and the corresponding judgment standard may be whether the real-time temperature value T1 of the heating area 21 reaches the preset temperature value T0. Specifically, after the infrared heating mode ends, the temperature value of the heating area 21 detected by the temperature sensor 5 is used as the selection judgment value of the temperature control parameter of the electromagnetic heating mode. When the real-time temperature value T1 of the heating area 21 reaches the preset temperature value T0, the cooking utensil 100 can determine that the residual temperature after heating by the infrared heating mode affects the start-up power of the electromagnetic heating mode, thereby reducing the user experience. That is, when the pre-stored conventional temperature control parameters are used at this time, even if the temperature of the pot 200 is relatively low, because the real-time temperature value of the heating area 21 is relatively high, the cooking utensil 100 will still limit the heating power of the electromagnetic heating mode to affect the heating of the pot 200 by the electromagnetic heating mode, thereby affecting the user experience. Although the temperature of the heating area 21 is not heated by the infrared heating mode and is in a heat dissipation state, it takes time for the heat to dissipate. Moreover, the higher the temperature of the heating area 21, the longer the heat dissipation time, which will still affect the starting power of the electromagnetic heating mode and affect the user experience of the electromagnetic heating mode during the heat dissipation time; on the contrary, when the real-time temperature value T1 of the heating area 21 is less than the preset temperature value T0, the cooking appliance 100 can determine that the influence of the residual temperature after heating in the infrared heating mode on the starting power of the electromagnetic heating mode is within an acceptable range, that is, the influence is small enough or even has no influence at all. At this time, the actual temperature of the heating area 21 is within an acceptable control range. Even if the pre-stored conventional temperature control parameters cause an influence on the starting power of the electromagnetic heating mode, the reduction value of the starting power is also within an acceptable range. The pot 200 can be started normally with an acceptable power and heated, meeting the needs of heating the pot 200 in the electromagnetic heating mode for cooking dishes. Therefore, the working parameter is set to the temperature value of the heating area 21, and the corresponding judgment standard is set to whether the real-time temperature value T1 of the heating area 21 reaches the preset temperature value T0, which is simple, intuitive and accurate.

[0083] Specifically, the preset temperature value T0 is set to be not less than 100°C. That is, when the electromagnetic heating mode is started and the temperature of the heating area 21 is less than 100°C, it can be determined that the pre-stored conventional temperature control parameters of the electromagnetic cooking appliance 100 do not limit the heating power of the electromagnetic heating component 32, that is, do not affect the normal start of the electromagnetic heating component 32. At this time, the pre-stored conventional temperature control parameters are used as the temperature control parameters of the electromagnetic heating mode, which will not affect the power of the electromagnetic heating component 32 when it is turned on. Therefore, at least the preset temperature value T0 is set to 100°C to avoid the situation where the pre-stored temperature control parameters are adjusted when the temperature of the heating area 21 is lower than 100°C, thereby avoiding the adjustment of invalid pre-stored temperature control parameters, reducing invalid control steps, and reducing the possibility of control logic abnormality. The specific value of the preset temperature value T0 is based on the user's acceptance of the degree of power reduction when the electromagnetic heating component 32 is turned on. The higher the selected value, the greater the startup power reduction of the electromagnetic heating component 32 when the real-time temperature T1 of the heating area 21 is lower than the selected value. Conversely, the reduction is smaller. This is not limited here. Furthermore, in this embodiment, the preset temperature value T0 is set to at least 200°C, that is, when the temperature of the heating area 21 is 100°C to 200°C, the temperature control parameters of the electromagnetic heating mode adopt the pre-stored conventional temperature control parameters. At this time, even if there is a limitation on the power of the electromagnetic heating component 32, the limitation amount must be small and can be basically ignored. Based on the same reason as the above-mentioned preset temperature value T0 is less than 100°C, the pre-stored temperature control parameters are not adjusted to reduce the control steps and simplify the control process; and in this embodiment, the preset temperature value T0 is set to 600°C at most. It can be understood that the infrared heating component 31 can be heated to a high temperature of about 600 degrees Celsius. If the preset temperature value T0 is set to greater than 600°C, it is basically equivalent to the real-time temperature T1 of the heating area 21 cannot reach the preset temperature value T0, so that the electromagnetic heating mode always uses the pre-stored temperature control parameters to operate, and the technical solution given in this application cannot be implemented, and there is no practical control significance. Therefore, in this embodiment, the preset temperature value T0 is set between 200°C and 600°C, and the specific value is still based on the user's acceptance of the degree of power reduction when the electromagnetic heating component 32 is turned on, and is not limited here. In particular, based on the user's acceptance of the degree of power reduction when the electromagnetic heating component 32 is turned on, multiple gears can actually be set to correspond to multiple preset temperature values ​​T0, so as to be suitable for different users.

[0084] In addition, in another embodiment of the control method of the cooking appliance 100, the step S210 includes:

[0085] S214: comparing the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode with the preset time t0;

[0086] S215: If t1>t0, the pre-stored temperature control parameters are used as the temperature control parameters of the electromagnetic heating mode;

[0087] S216: If t1≤t0, the pre-stored temperature control parameters are adjusted, and the adjusted temperature control parameters are used as the temperature control parameters of the electromagnetic heating mode.

[0088] Different from the above-mentioned one embodiment of the control method of the cooking appliance 100 in which the temperature value of the heating area 21 is used for intuitive judgment, the present embodiment mainly uses the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating component 32 as the basis for judgment, that is, the static time of the cooking appliance 100 is used as the basis for judgment, or the heat dissipation time of the cooking appliance 100 after the infrared heating mode ends. Compared with the intuitive judgment based on the temperature value of the heating area 21, it can be understood that the scheme given in the present embodiment indirectly reflects the possible temperature of the heating area 21 after the infrared heating mode ends, and the judgment accuracy of the status of the heating area 21 is bound to be poor. However, the specific value of the preset time t0 can also be summarized and refined through multiple data experiments in the research and development stage to improve the accuracy as much as possible. Specifically, the heating area 21 can be heated to the highest temperature value by using the rated heating power of the infrared heating mode, and then the infrared can be turned off. The external heating component 31 is used to obtain the longest heat dissipation time for the heating area 21 to cool down to the preset temperature, and the preset time t0 is used as the preset time, wherein the preset temperature value is the maximum temperature at which the power reduction degree corresponding to the preset temperature value in the pre-stored conventional temperature control parameters can be accepted when the electromagnetic heating component 32 operates with the pre-stored conventional temperature control parameters. Under this condition, if the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode is greater than the preset time t0, the temperature of the heating area 21 must be lower than the preset temperature, and the pre-stored conventional temperature control parameters can be used, which can be accepted by the user; on the contrary, if the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode is not greater than the preset time t0, the temperature of the heating area 21 is at least the preset temperature, and is very likely to exceed the preset temperature. At this time, the pre-stored temperature control parameters need to be adjusted to avoid excessive impact on the starting power of the electromagnetic heating component 32 and not being accepted by the user, thereby avoiding affecting the user's experience. Of course, it is understandable that there are many test process methods for obtaining the preset time t0 through test data. The above example is only one of the implementation methods given, which is not limited here, and is based on the actual product development process and customer needs. Therefore, the scheme of whether to adjust the pre-stored temperature control parameters based on the interval time from the end of the infrared heating mode to the start of the electromagnetic heating mode is poor in accuracy compared to the intuitive judgment based on the temperature value of the heating area 21, but its accuracy can also meet the use requirements of the cooking appliance 100 proposed in this application based on the test data, and can be used as another implementation of the control method of the cooking appliance 100.

[0089] Specifically, before step S100, the method further includes the following steps:

[0090] S110: Record the end time of the infrared heating mode.

[0091] In order to be applicable to the above-mentioned judgment control method of whether to adjust the pre-stored temperature control parameters through the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode, the end time point needs to be recorded when the infrared heating mode ends, so as to obtain the start time point of the electromagnetic heating mode when the electromagnetic heating mode is started, and then calculate the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode based on the above two time points to meet the use requirements. Of course, a timer can also be set in the cooking appliance 100, and after the infrared heating mode ends, the timer is started until the electromagnetic heating mode is started, and the time length recorded by the timer is obtained to obtain the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode. However, it is understandable that by recording the time points to obtain the duration, it is possible to avoid the situation where the electromagnetic heating mode is no longer turned on after the infrared heating mode ends. If a timer is used to record the duration, an additional timing upper limit needs to be set when encountering the above situation to avoid invalid recording for a long time. Specifically, the duration can be obtained by using one of the above two methods, or by other methods. It is sufficient to obtain the interval time t1 from the end of the infrared heating mode to the start of the electromagnetic heating mode, and there is no limitation here.

[0092] Specifically, t0≤30min. Similar to judging whether to adjust the pre-stored temperature control parameters by the temperature of the heating area 21, when the cooling of the heating area 21 reaches 30min, the temperature of the heating area 21 has dropped to a level that does not limit the starting power of the electromagnetic heating component 32 using conventional temperature control parameters, and there is no need to adjust the pre-stored temperature control parameters. If t0 is set to be greater than 30min, there will be invalid adjustments. Therefore, in this application, the preset time t0 is limited to no more than 30min. Furthermore, when the cooling time of the heating area 21 is 20min to 30min, there may be a certain amount of residual heat, but the pre-stored conventional temperature control parameters corresponding to the residual heat temperature have a weak power limit on the electromagnetic heating component 32, that is, the power limit on the electromagnetic heating component 32 is within the range that can be accepted by the user. In order to reduce the adjustment of the pre-stored temperature control parameters and reduce the control process, this application limits the preset time t0 to no more than 20min. In addition, for the case where the cooling time of the heating area 21 is less than 5 minutes, the temperature reduction value of the heating area 21 is small. Based on the fact that the heating area 21 is at the extreme heating temperature of the infrared heating mode and is cooled for a maximum of 5 minutes, the temperature of the heating area 21 has a significant impact on the starting power of the electromagnetic heating component 32 using the pre-stored conventional temperature control parameters, affecting the user experience of the cooking utensil 100. Therefore, in this application, the preset time t0 is set to at least 5 minutes to avoid the situation where the power of the electromagnetic heating component 32 is severely reduced or even cannot be turned on normally when the cooking utensil 100 determines that there is no need to adjust the pre-stored temperature control parameters.

[0093] It should be noted that the usage scenario of the cooking appliance 100 may also include the situation where the infrared heating mode is not turned off after being started, and then the electromagnetic heating mode is started. In this case, in order to ensure the normal operation of the electromagnetic heating mode, the temperature control program of the electromagnetic heating mode can be directly turned off to avoid affecting the power of the electromagnetic heating mode and ensure the user experience. However, if there is no restriction, the heating temperature may be too high and not suitable for cooking. Therefore, on this basis, the maximum temperature value of the heating area 21 can be set not to exceed the maximum temperature value that the infrared heating mode can heat. Generally, it can be set to 600°C to ensure that the overall temperature of the pot 200 does not exceed 600°C and to ensure that the temperature of the pot 200 is controllable.

[0094] In addition, the step S220 includes:

[0095] S221: according to the judgment result, the adjusted temperature control parameter is used as the temperature control parameter of the electromagnetic heating mode;

[0096] The step S300 correspondingly includes:

[0097] S310: comparing the operation time t2 of the electromagnetic heating component 32 running with the adjusted temperature control parameters with the preset operation time t3;

[0098] S320: If t2 ≥ t3, the electromagnetic heating component 32 is controlled to operate with pre-stored temperature control parameters.

[0099] After determining that the pre-stored temperature control parameters need to be adjusted as the temperature control parameters of the electromagnetic heating mode to meet the user's usage requirements and avoid affecting the user's usage experience, the electromagnetic heating component 32 is started with the adjusted pre-stored parameters. At this time, the power limit of the electromagnetic heating component 32 is small or even not limited. As the electromagnetic heating component 32 heats the pot 200 and the heating area 21 dissipates heat and cools, the temperature of the heating area 21 and the pot 200 tend to be the same, and may exceed the maximum temperature control temperature set by the pre-stored temperature control parameters, that is, exceed the optimal cooking temperature of the pot 200. At this time, in order to maintain and ensure the temperature of the pot 200, the temperature control parameters of the electromagnetic heating mode need to be adjusted back to the pre-stored temperature control parameters. The conventional temperature control parameters set are controlled and called back by detecting the temperature of the pot 200, which is the most accurate method. However, the cooking utensil 100 generally detects the temperature of the heating area 21. At this time, the temperature of the heating area 21 is not necessarily consistent with the temperature of the pot 200, and there is uncertainty. Therefore, the present application proposes to use the length of time that the electromagnetic heating component 32 runs with the adjusted temperature control parameters as the basis for judging whether it is necessary to call back to the preset conventional temperature control parameters. With the support of test data, a more accurate preset time t3 for heating the pot 200 to the optimal temperature can be summarized, so as to make a more accurate judgment on whether to call back the temperature control parameters of the electromagnetic heating mode to meet the usage requirements.

[0100] Specifically, t3≥5s. The preset duration t3 is set to at least 5s to avoid frequent adjustment of the temperature control parameters of the electromagnetic heating mode in a short period of time, thereby avoiding failure of the control system of the cooking utensil 100. Furthermore, 3min≤t3≤5min. In order to ensure that the electromagnetic heating mode heats the pot 200 to the required cooking temperature, the present application limits the preset duration t3 to 3min. At the same time, in order to avoid heating the pot 200 to too high a temperature, the preset duration t3 is limited to no more than 5min. The acquisition of this data is based on the electromagnetic heating component 32 heating the pot 200 at rated power. The time for heating the pot 200 to the minimum required cooking temperature and the maximum temperature limit at room temperature is used as the range of the preset duration t3. The specific duration is not limited, and is mainly based on actual needs. Of course, other methods of obtaining the duration range can also be used to ensure that the temperature of the pot 200 is maintained below the optimal temperature, which is not limited here to avoid excessive temperature affecting the cooking effect.

[0101] In addition, the step S300 includes:

[0102] S330: obtaining a real-time temperature value T1 of the heating area 21, and obtaining an electromagnetic heating power W corresponding to the real-time temperature value T1 preset in the temperature control parameter;

[0103] S340: Control the electromagnetic heating component 32 to operate at the electromagnetic heating power W.

[0104] The temperature control parameter is the corresponding relationship between the temperature value of the heating area 21 and the heating power of the electromagnetic heating component 32. The conventional setting is that the higher the temperature value, the greater the restriction on the heating power, until the electromagnetic heating component 32 is turned off. In this application, the pre-stored conventional temperature parameter is that when the real-time temperature value T1≤150℃, the electromagnetic heating power W is the rated power value, and W>1700W; when 150℃<T1≤160℃, 1500W≤W≤1700W; when 160℃<T1≤170℃, then 900W≤W≤1100W; when 170℃<T1≤180℃, then 400W≤W≤600W; when 180℃<T1, then W=0. The temperature value of the pot 200 is controlled at a maximum of 180℃, which meets the cooking needs while avoiding excessive temperature affecting the cooking effect.

[0105] Specifically, the temperature judgment threshold of the pre-stored temperature control parameter is increased to form the adjusted temperature control parameter. The temperature control parameter can be adjusted by synchronously adjusting the threshold of the temperature value range of the conventional temperature control parameter, or by expanding the span of each temperature value range to cover the maximum heating temperature of the infrared heating mode, or by directly releasing the temperature control parameter to cancel the control of the heating temperature, so that the electromagnetic heating component 32 is heated at the rated power value, which can reduce the impact on the heating power of the electromagnetic heating component 32, and is not limited here.

[0106] Specifically, the present application adopts the method of raising the temperature judgment threshold of the pre-stored temperature control parameter to form the adjusted temperature control parameter. The difference between the temperature judgment threshold of the pre-stored temperature control parameter and the adjusted temperature control parameter is T2. Then, according to the pre-stored conventional temperature control parameter, the adjusted temperature control parameter is when the real-time temperature is T1≤150℃+T2, the electromagnetic heating power W is the rated power value, and W>1700W; when 150℃+T2<T1≤160℃+T2, 1500W≤W≤1700W; when 160℃+T2<T1≤170℃+T2, 900W≤W≤1100W; when 170℃+T2<T1≤180℃+T2, 400W≤W≤600W; when 180℃+T2<T1, W=0. In this way, it is equivalent to taking the initial temperature of the heating area 21 as the basic temperature value, so as to eliminate the temperature rise value of the heating area 21 heated by the infrared heating mode on the basis of the pre-stored conventional temperature control parameters. The basic control logic and temperature control range are not changed, so as to facilitate the switching between the pre-stored temperature control parameters and the adjusted temperature control parameters, thereby reducing the difficulty of control design.

[0107] Specifically, the difference between the temperature judgment thresholds of the pre-stored temperature control parameters and the adjusted temperature control parameters is T2, T2 ≥ 5°C. When the difference between the above judgment thresholds is less than 5°C, based on the temperature error of the temperature sensor 5 itself, it is impossible to distinguish the pre-stored temperature control parameters and the adjusted temperature control parameters during actual use, that is, the practicality is poor. Specifically, the present application sets the difference between the judgment thresholds to at least 5°C, and further 20°C ≤ T2 ≤ 100°C to meet the use requirements.
