Description

Technical Field

[0001] This specification relates to the technical field of stove temperature control, and particularly to a temperature control device and method. Background Art

[0002] As the intelligence level of stoves is getting higher and higher, especially intelligent cooking has become the main choice for most users. The core technology to achieve intelligent cooking is to accurately control the temperature of the cookware, so as to ensure that the cooked food meets the edible needs of users. In a drum cooking system, the drum for stir-frying is a device that rotates relative to the heating coil. The drum is generally provided with a temperature acquisition device. Since the infrared sensor is easily affected by dirt and leads to inaccurate measurement, therefore, the temperature measurement of the drum mostly uses a temperature acquisition device fixed on the drum body of the drum and rotating with the drum, such as a thermocouple, and the temperature measurement accuracy is higher; in the prior art, when the heating coil heats the drum, the heating coil often cannot cover the entire circumference of the drum. When cooking in an inclined state of the drum, the food is always at the bottom side of the drum. Due to the fixed layout relationship of the temperature acquisition device on the drum, the temperature acquisition device rotates with the drum. When the temperature acquisition device rotates out of the area where the food is located, the temperature collected by the temperature acquisition device is no longer the temperature of the drum body part that heats the food, resulting in the temperature acquisition device being unable to accurately collect the actual temperature of the drum part for actually heating the food in the rotating drum, that is, unable to accurately understand the actual temperature of the pot body that heats the food. Therefore, when adjusting the output power based on the temperature value deviating from the actual temperature, problems such as irregular power reduction or stop heating will occur, and the power output cannot be accurately controlled, resulting in uneven heating of the food and unable to cook food with a good taste. Therefore, an effective solution is urgently needed to solve the above problems. Summary of the Invention

[0055] Many specific details are set forth in the following description in order to provide a thorough understanding of this specification. However, this specification can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of this specification. Therefore, this specification is not limited by the specific implementations disclosed below.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of this specification, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0058] In this specification, a temperature control device is provided. This specification also relates to a temperature control method, which will be described in detail one by one in the following embodiments.

[0059] In a drum cooking system, after the drum is heated by a heating component to a high temperature point, it is necessary to slow down the temperature rise of the drum body or achieve the purpose of cooling by reducing the power or stopping heating. However, during the process of processing food ingredients, the high-temperature stage of the pot body is exactly the stage where a large amount of heat transfer is required during cooking. Simply and roughly reducing the power or stopping heating irregularly will cause the temperature rise of the food ingredients to be hindered, thus greatly affecting the taste of the cooked food ingredients. The main reason for the temperature change is still that the temperature acquisition device cannot accurately acquire the actual temperature of the drum, so there will be a certain lag when adjusting the output power, affecting the timeliness of power adjustment.

[0060] In view of this, the temperature control device provided in this specification includes a drum; at least one temperature acquisition device for acquiring the temperature of the drum; and a heating component for adjusting the output power according to the temperature acquired by the temperature acquisition device; wherein at least one temperature acquisition device fixedly connected to the drum is located in the heating area of the heating component; it is realized that when acquiring the temperature of the drum, it can be ensured at any time that the temperature acquisition device is located in the heating area of the heating component, so as to ensure that the temperature acquired by the temperature acquisition device is the actual temperature of the drum, which is convenient for the heating component to adjust the output power in combination with the acquired actual temperature, so as to cook food with better taste through the drum cooking outlet.

[0061] As Figures 1 to 4 shown in the cross-sectional view of the temperature control device, the temperature control device includes a drum 101; at least one temperature acquisition device 102, the temperature acquisition device 102 is configured to acquire the temperature of the drum 101; a heating component 103, the heating component 103 is configured to adjust the output power based on the temperature acquired by the temperature acquisition device 102; wherein at least one temperature acquisition device 102 fixedly connected to the drum 101 is located in the heating area of the heating component 103.

[0062] Specifically, the drum 101 specifically refers to a holding device for holding the object to be heated, and the objects held therein include but are not limited to nuts, vegetables, or staple foods, etc.; correspondingly, the drum is arranged with one side open and one side closed, the closed side is connected to a transmission shaft, the transmission shaft is connected to a motor, and the drum rotates under the drive of the transmission shaft connected to the motor to tumble the food materials in the drum. Correspondingly, the temperature acquisition device 102 specifically refers to a temperature sensor for acquiring the temperature of the drum, including but not limited to a thermocouple temperature sensor or a thermal resistance temperature sensor, etc. In practical applications, it can be selected according to requirements, and this embodiment does not make any limitation here. Among them, the temperature acquisition device is fixedly connected to the surface of the drum and rotates together with the drum; it is arranged in the rolling heated area to facilitate accurate acquisition of the actual temperature of the drum, that is, the temperature acquisition devices are distributed along the same circumference. Correspondingly, the heating component 103 specifically refers to a device for heating the drum, which includes but is not limited to a resistance coil or an electromagnetic coil, etc., and is used to complete the heating of the drum.

[0063] In practical applications, considering that when the heating component 103 heats the drum 101, in order to avoid uneven heating of the food materials inside the drum 101, the drum 101 will tumble the food materials inside by rotating; at this time, if the temperature acquisition device 102 fixedly connected to the outside of the drum 101 cannot be located in the heating area of the heating component 103 at any rotation moment, the temperature acquisition device 102 will not be able to acquire the current true maximum temperature value of the drum 101; for example Figure 2 in (a) and Figure 2 in the schematic diagrams shown in (b), when the number of temperature acquisition devices 102 is too small, or the distance between two adjacent temperature acquisition devices 102 is greater than the distance of the heating area of the heating component 103, the problem that the temperature acquisition device 102 is not located in the heating area at a certain moment will occur, and at this time, the maximum temperature value of the drum 101 cannot be truly reflected, which will affect the subsequent power adjustment.

[0064] Based on this, in order to ensure that the actual temperature value of the drum 101 can be accurately acquired at any moment, at least one temperature acquisition device 102 fixedly connected to the drum 101 can be arranged to be located in the heating area of the heating component 103. That is to say, no matter how many temperature acquisition devices 102 are fixedly connected to the drum 101, it is necessary to ensure that they will be located in the heating area of the heating component 103 at any moment. In practical applications, the distance between the temperature acquisition devices 102 can be reduced by designing the diameter of the drum, or the heating area range of the heating component 103 can be increased. Specifically in implementation, it can be selected according to actual requirements, and this embodiment does not make any limitation here.

[0065] In this embodiment, in order to support the temperature acquisition device 102 to acquire the actual temperature of the drum, on the one hand, when the number of the temperature acquisition devices 102 is one, the heating component 103 is in a circular ring shape and covers the heated area of the drum 101. Among them, the heated area specifically refers to the area of the drum 101 heated by the heating component 103 during the rotation process, that is, the heating belt of the drum 101.

[0066] See Figure 3 In the schematic diagram shown, when the number of temperature acquisition devices provided on the drum 101 is one, in order to support the temperature acquisition device to accurately acquire the actual temperature of the drum 101, the heating component 103 can be set in a circular ring shape and surround the heated area of the drum 101, so that the drum 101 can be heated comprehensively.

[0067] In summary, by reducing the number of temperature acquisition devices and increasing the heating area of the heating component, the temperature acquisition device can be located in the heating area of the heating component at any time, accurately acquire the actual temperature of the drum, and facilitate the subsequent adjustment of the output power in combination with the temperature value fed back by the temperature acquisition device.

[0068] On the other hand, when the number of the temperature acquisition devices 102 is multiple, the heating area of the heating component 103 is larger than the heated area between any two adjacent temperature acquisition devices 102, and each temperature acquisition device 102 is evenly distributed along the heated area of the drum 101.

[0069] Based on this, multiple temperature acquisition devices 102 can also be provided for the drum 101. At this time, in order to ensure that the temperature acquisition device is located in the heating area at any time, the heating area of the heating component can be set to be larger than the heated area between any two adjacent temperature acquisition devices 102. That is to say, even when the temperature acquisition devices 102 are unevenly distributed on the same circumference of the drum, it can be ensured that the two temperature acquisition devices with the largest adjacent spacing can be covered by the heated area.

[0070] For example, see Figure 4As shown in Fig. (a), three temperature acquisition devices are arranged on the drum 101, namely temperature acquisition device 1021, temperature acquisition device 1022, and temperature acquisition device 1023. Among them, the three temperature acquisition devices are not equally spaced. The distance between temperature acquisition device 1021 and temperature acquisition device 1022 is πr / 2, the distance between temperature acquisition device 1022 and temperature acquisition device 1023 is πr, and the distance between temperature acquisition device 1023 and temperature acquisition device 1021 is πr / 2. In order to ensure that at least one temperature acquisition device is located in the heating area of the heating component at any time, the heating area of the heating component 103 can be set to be larger than the heated area between temperature acquisition device 1022 and temperature acquisition device 1023. That is to say, the arc length of the heating component 103 is greater than πr.

[0071] In addition, in order to improve resource utilization, that is, the number of temperature acquisition devices 102 is the least and the heating area of the heating component 103 is also the smallest, a set number of temperature acquisition devices 102 can be fixedly connected to the drum 101, and each temperature acquisition device 102 is equally spaced along the heated area of the drum 101.

[0072] For example, referring to Figure 4 As shown in Fig. (b), four temperature acquisition devices are arranged on the drum 101, namely temperature acquisition device 1021, temperature acquisition device 1022, temperature acquisition device 1023, and temperature acquisition device 1024. Among them, the four temperature acquisition devices are equally spaced along the same circumference of the drum 101, that is, the distance between any two adjacent temperature acquisition devices is πr / 2. Then the heating area of the heating component 103 is larger than the heated area between any two adjacent temperature acquisition devices. That is to say, the arc length of the heating component 103 is greater than πr / 2.

[0073] In summary, the temperature control device provided in this embodiment realizes that at least one temperature acquisition device fixedly connected to the drum is located in the heating area of the heating component; when collecting the temperature of the drum, it can ensure that the temperature acquisition device is located in the heating area of the heating component at any time, so as to ensure that the temperature collected by the temperature acquisition device is the actual temperature of the drum, which is convenient for the heating component to adjust the output power in combination with the collected actual temperature, so as to cook food with better taste through the drum.

[0074] Figure 5 Fig. shows a flowchart of a temperature control method provided according to an embodiment of this specification, which specifically includes the following steps:

[0075] Step S502, obtain the temperature data collected by the temperature acquisition device according to a preset time period.

[0076] The temperature control method provided in this embodiment is applied to the processing end of the temperature control device, which is used to adjust the output power according to the temperature value feedback by the temperature acquisition device, or the rotation speed of the drum in the temperature control device, or the posture of the work station. It should be noted that the processing end is communicatively connected to the temperature control device.

[0077] It should be noted that for the temperature control method provided in this embodiment and the above-described temperature control device embodiment, the same or corresponding description contents can be referred to each other, and this embodiment will not elaborate too much here.

[0078] Specifically, the preset time period specifically refers to the period for adjusting the temperature control device. By processing the temperature values collected in each time period, the virtual temperature parameter of the drum is obtained, which is convenient for subsequent adjustment of the temperature control device based on this. Correspondingly, the temperature data specifically refers to the set of temperature values collected by all temperature acquisition devices, and the temperature values in the temperature data correspond to different time nodes within the preset time period, that is, the preset time period contains at least one time node.

[0079] In practical applications, the length of the preset time period can be set according to the actual application scenario, such as set to 2s, 5s, or 8s, etc., and this embodiment does not make any limitation here. In addition, the preset time period can also be dynamically determined, which depends on the rotation speed of the drum. That is to say, the interval between any two adjacent time nodes in the preset time period should be less than the time for the drum to rotate one week, so as to ensure that the temperature collected by the temperature acquisition device is the value that reflects the actual temperature of the drum, and to avoid the situation that multiple temperature values collected by the same temperature acquisition device may all be in the cooling time period or the heating time period, or part in the heating time period and part in the cooling time period, resulting in the calculated virtual temperature parameter not being able to truly represent the actual temperature of the drum.

[0080] Step S504, calculate the virtual temperature parameter corresponding to the drum according to the temperature data.

[0081] Specifically, after obtaining the temperature data composed of the temperature values collected by the temperature acquisition device as described above, further, in order to facilitate subsequent precise adjustment of the temperature control device based on the temperature data to meet the heating requirements of the food materials in the drum, the virtual temperature parameter corresponding to the drum can be calculated based on the temperature data. Among them, the virtual temperature parameter is a parameter representing the actual temperature data corresponding to the drum, and the virtual temperature parameter can be the temperature value or the temperature rise value corresponding to the drum; both the temperature value and the temperature rise value can reflect the heating state of the drum at the current moment, so as to adjust the temperature control device in combination with the temperature value or the temperature rise value.

[0082] It should be noted that when there is a maximum value in the temperature values of the temperature data, it indicates that the temperature acquisition device is located within the heating area of the heating component. Therefore, selecting the highest temperature value as the virtual temperature parameter can truly reflect the actual temperature of the drum.

[0083] Furthermore, when the virtual temperature parameter corresponding to the drum is a temperature value, in order to accurately feedback the virtual temperature corresponding to the drum to facilitate subsequent adjustment of the temperature control device, the following method can be used to determine the virtual temperature parameter corresponding to the drum. In this embodiment, the specific implementation method is as follows:

[0084] (1) Select the highest temperature value in the temperature data as the virtual temperature parameter.

[0085] Specifically, when the temperature data is a single set, it is determined that the temperature values collected by the temperature acquisition device all exist in this set of temperature data. At this time, the highest temperature value in this set of temperature data can be selected as the virtual temperature parameter to represent the actual temperature corresponding to the drum at the current moment, so as to realize subsequent adjustment of the temperature control device in combination with the highest temperature value.

[0086] For example, there are 3 temperature sensors fixedly connected to the drum, namely temperature sensors 1, 2, and 3; at time t1, the temperature of the drum collected by temperature sensor 1 is T1, the temperature of the drum collected by temperature sensor 2 is T2, and the temperature of the drum collected by temperature sensor 3 is T3. If it is determined that T2 > T1 > T3, then the temperature T2 can be selected as the virtual temperature value of the drum at this time, so as to realize subsequent adjustment of the temperature control device in combination with this temperature value.

[0087] (2) Select the temperature value corresponding to the target time node in the temperature data as the virtual temperature parameter.

[0088] Specifically, the target time node specifically refers to a designated time node within a preset time period. Based on this, in order to determine the virtual temperature parameter of the drum in the same time dimension, the target time node can be selected first, and then the temperature values feedback by each temperature acquisition device at this time node are determined in the temperature data, and then one of these temperature values can be selected as the virtual temperature parameter of the drum.

[0089] For example, there are 6 temperature sensors fixed on the drum, namely temperature sensors 1, 2, 3, 4, 5, and 6. Among them, temperature sensors 1, 2, and 3 belong to the first group, and temperature sensors 4, 5, and 6 belong to the second group. Correspondingly, within a preset time period, there are three time nodes, namely t1, t2, and t3. Based on this, t2 is selected as the target time node; based on the temperature data collected by the temperature sensors, it is determined that at time t2, the temperatures collected by temperature sensors 1, 2, and 3 in the first group are T 1-2 , T 2-2 and T 3-2 ; the temperatures collected by temperature sensors 4, 5, and 6 in the second group are T 4-2 , T 5-2 and T 6-2 . By comparing T 1-2 , T 2-2 , T 3-2 , T 4-2 , T 5-2 and T 6-2 , it is determined that T 3-2 is the largest. Then, at this time, the temperature T 3-2 can be selected as the virtual temperature value of the drum, so as to realize the subsequent adjustment of the temperature control device in combination with this temperature value.

[0090] (3) Select the average temperature corresponding to the target time period in the temperature data as the virtual temperature parameter.

[0091] Specifically, the target time period specifically refers to the time length less than or equal to the preset time period, and the target time period is within the preset time period interval. Based on this, the virtual temperature parameter of the drum can also be determined by calculating the average temperature. When there are multiple groups of temperature data, the highest average temperature can be selected as the virtual temperature parameter by comparison.

[0092] Continuing with the above example, the virtual temperature parameter can be selected by calculating the average temperature corresponding to the temperature sensors included in each group. That is, first calculate the average temperature of each temperature sensor, and then calculate the average temperature of each group. It is determined that the average temperature corresponding to the first group is T 11 , and the average temperature corresponding to the second group is T 21 . Then compare the two to determine that the average temperature T 11 is the largest. Then, at this time, the average temperature T 11 can be selected as the virtual temperature value of the drum, so as to realize the subsequent adjustment of the temperature control device in combination with this temperature value.

[0093] (4) Select the highest temperature value corresponding to the target time interval in the temperature data as the virtual temperature parameter.

[0094] Specifically, the target time interval specifically refers to a specified time interval within a set time period, and the target time interval is within a preset time period interval. Based on this, the highest temperature value of the target time interval can also be selected as the virtual temperature parameter.

[0095] Continuing with the above example, it is determined that the target time interval includes the moments t1 and t2; by comparing the temperature values corresponding to each temperature sensor at the moments t1 and t2 respectively, it is determined that the temperature value T of the temperature sensor 3 at the moment t2 3-2 is the maximum. At this time, the temperature T 3-2 can be selected as the virtual temperature value of the drum, so as to realize the subsequent adjustment of the temperature control device in combination with this temperature value.

[0096] In summary, by using the temperature value as the virtual temperature parameter of the drum, it is convenient to subsequently adjust the temperature control device based on the temperature value, and it can more intuitively reflect the actual temperature of the drum, thereby ensuring the accuracy of the adjustment.

[0097] Furthermore, when the virtual temperature parameter corresponding to the drum is the temperature rise value, it is also possible to determine whether the drum is in a heating state or a cooling state at the current moment according to the temperature rise value, and then select the temperature data group in the heating state to determine the virtual temperature parameter of the drum, so as to facilitate the subsequent adjustment of the temperature control device. In this embodiment, the specific implementation method is as follows from step S5022 to step S5026:

[0098] Step S5022: Divide the temperature data into at least one temperature data group.

[0099] Step S5024: Screen out the target heating data group from the at least one temperature data group.

[0100] Specifically, the temperature data group specifically refers to a group of temperature data composed of the temperatures collected by the temperature acquisition device, and the layout relationship of the temperature acquisition devices corresponding to the temperature values in the same group has an adjacent relationship or a symmetric relationship, ensuring that the temperature acquisition devices in the same group are all temperature acquisition devices that feedback the actual temperature of the drum to be similar at a certain moment. Correspondingly, the heating data group specifically refers to a data group composed of the temperature values in the heating state in the temperature data group, and the target heating data group is the heating data group used to feedback the virtual temperature parameter corresponding to the drum.

[0101] When the temperature acquisition device collects the actual temperature of the drum, it may be located or not located in the heating area of the heating component. At this time, after different temperature acquisition devices collect the temperature, it can be compared with the temperature at the previous time node to determine whether it is a temperature increase or decrease. In fact, the heating component is constantly heating the drum. Therefore, the data feedback of temperature decrease can be discarded. Only through the data of temperature increase can the actual temperature of the drum be truly reflected, and then the subsequent adjustment of the temperature control device can be accurately carried out.

[0102] Furthermore, when there is only one temperature data group, the virtual temperature parameter can be directly determined based on the temperature value of this temperature data group; when there are multiple temperature data groups, there may also be multiple temperature increase data groups. Therefore, it is necessary to select the target temperature increase data group from multiple temperature increase data groups to calculate the virtual temperature parameter corresponding to the drum before subsequent device adjustment can be carried out. In this embodiment, the process of selecting the target temperature increase data group from at least one temperature data group is as follows in steps S50242 to S50250:

[0103] Step S50242: Determine the highest temperature value corresponding to each time node in each temperature data group within the time period.

[0104] Step S50244: Calculate the temperature rise value between any two adjacent time nodes based on the highest temperature value.

[0105] Step S50246: Determine the temperature rise parameter corresponding to each temperature data group according to the temperature rise value.

[0106] Specifically, the highest temperature value corresponding to each time node specifically refers to selecting the highest temperature value of each temperature acquisition device in the same time node of each group of temperature data; correspondingly, the temperature rise value specifically refers to the temperature rise rate, that is, the temperature increase rate corresponding to each group of temperature data; correspondingly, the temperature rise parameter characterizes the temperature rise rate corresponding to each temperature data group, and the larger the temperature rise parameter, the faster the temperature change.

[0107] Based on this, in order to be able to screen out the target temperature increase data group from at least one temperature data group and thus accurately determine the virtual temperature parameter of the drum in combination with the temperature rise parameter of the target temperature increase data group, the temperature value of each time node in each temperature data group within the preset time period can be first determined, then the highest temperature value corresponding to each time node can be selected to calculate the temperature rise value between any two adjacent time nodes, and then the temperature rise parameter of each temperature data group can be determined in combination with the temperature rise value, so as to realize subsequent screening of the target temperature increase data group in combination with the temperature rise parameter.

[0108] It should be noted that when calculating the temperature rise value, in fact, the difference between any two adjacent highest temperature values is calculated, and then the difference is compared with the difference between two time nodes to obtain the temperature rise value corresponding to this time period.

[0109] Furthermore, when determining the temperature rise parameter corresponding to each temperature data group according to the temperature rise value, in order to be able to truly reflect the temperature rise rate of each temperature data group through the temperature rise parameter and facilitate subsequent accurate screening of the target temperature rise data group from multiple temperature rise data groups, it can be achieved through the following three methods. In this embodiment, the specific implementation methods are as follows:

[0110] (1) Select the temperature rise value between any two adjacent target time nodes as the temperature rise parameter.

[0111] (2) Calculate the average temperature rise value corresponding to the temperature data group according to the temperature rise value between any two adjacent time nodes, and use the average temperature rise value as the temperature rise parameter.

[0112] (3) Select the highest temperature rise value between any two adjacent time nodes within the target time period as the temperature rise parameter, where the target time period is less than or equal to the time period.

[0113] For the convenience of description in this embodiment, the process of calculating the temperature rise parameter corresponding to a temperature data group is described. The calculation processes of other temperature data groups can refer to the same or corresponding description content of this embodiment, and will not be elaborated here.

[0114] Based on this, it is determined that there are three temperature sensors in this temperature data, namely 1, 2, and 3; and at time t1 within the preset time period, the temperatures collected by each temperature sensor are T 1-1 , T 2-1 and T 3-1 ; at time t2, the temperatures collected by each temperature sensor are T 1-2 , T 2-2 and T 3-2 ; at time t3, the temperatures collected by each temperature sensor are T 1-3 , T 2-3 and T 3-3 . By comparison, it is determined that the highest temperature value corresponding to time t1 is T 2-1 , the highest temperature value corresponding to time t2 is T 3-2 , and the highest temperature value corresponding to time t3 is T 1-3 . Furthermore, according to T 2-1 and T 3-2 , the temperature rise value between time nodes t1 - t2 is calculated as k1; according to T 3-2 and T 1-3, the temperature rise value between the time nodes of t2 - t3 is calculated as k2.

[0115] When it is necessary to select the temperature rise value between the time nodes of t1 - t2 as the temperature rise parameter corresponding to this set of temperature data, then determine that the temperature rise parameter corresponding to this set of temperature data is k1.

[0116] When it is necessary to select the average temperature rise value as the temperature rise parameter corresponding to this set of temperature data, then determine that the temperature rise parameter corresponding to this set of temperature data is (k1 + k2) / 2.

[0117] When it is necessary to select the maximum temperature rise value as the temperature rise parameter corresponding to this set of temperature data, then determine that the temperature rise parameter corresponding to this set of temperature data is k1; where k1 > k2.

[0118] In practical applications, when determining the temperature rise parameter corresponding to each set of temperature data, it can be selected according to actual needs, and this embodiment does not make any limitations here.

[0119] Step S50248, compare the temperature rise parameter with a preset temperature rise threshold, and select the temperature data group greater than the temperature rise threshold as the initial temperature rise data group.

[0120] Step S50250, screen out the target temperature rise data group based on the temperature rise parameter corresponding to the initial temperature rise data group.

[0121] Specifically, the temperature rise threshold specifically refers to a preset value for comparison with the temperature rise parameter. It should be noted that different temperature rise parameters calculated by different methods will correspond to different temperature rise thresholds, so as to ensure that the initial temperature rise data group is accurately screened out by comparing the temperature rise thresholds, so as to facilitate the subsequent determination of the virtual temperature parameter corresponding to the drum in combination with the target temperature rise data group. Correspondingly, the initial temperature rise data group specifically refers to the data group in the temperature data group that is in the temperature rise state.

[0122] Based on this, after determining the temperature rise parameter corresponding to each temperature data group, in order to be able to screen out the temperature rise data group for subsequent determination of the virtual temperature parameter of the drum, at this time, the temperature rise parameter can be compared with a preset temperature rise threshold, and the temperature data group greater than the temperature rise threshold is selected as the initial temperature rise data group, and then the target temperature rise data group can be screened out in combination with the temperature rise parameter corresponding to the initial temperature rise data group.

[0123] When screening the target heating data group based on the temperature rise parameters of each initial heating data, in fact, the temperature rise parameters corresponding to each initial heating data group are compared. In this embodiment, the specific implementation method is as follows: compare the temperature rise parameters corresponding to each initial heating data group; screen the initial heating data group with the highest temperature rise parameter according to the comparison result as the target heating data group. That is to say, by selecting the initial heating data group with the fastest heating rate as the target heating data.

[0124] In practical applications, the temperature rise threshold can be set to 0 or other defined values. The temperature rise threshold can be set according to actual needs, and this embodiment does not make any limitations here.

[0125] Step S5026, determine the virtual temperature parameter according to the temperature rise parameter corresponding to the target heating data group.

[0126] Specifically, after screening out the target heating data group in combination with the temperature rise parameter, further, directly use the temperature rise parameter corresponding to the target heating data group as the virtual temperature parameter of the drum.

[0127] Continuing with the above example, it is determined that the temperature rise parameter corresponding to the first temperature data group is k 11 , the temperature rise parameter corresponding to the second temperature data group is k 22 , the temperature rise parameter corresponding to the third temperature data group is k 33 . By comparing the temperature rise parameter corresponding to each temperature data group with the temperature rise threshold k0, it is determined that k 33 is less than the temperature rise threshold, and it belongs to the cooling data group and can be discarded; then compare the temperature rise parameters k 11 and k 22 , and determine k 11 > k 22 according to the comparison result; then select the first temperature data group corresponding to the temperature rise parameter k 11 as the target heating data group, and use the temperature rise parameter k 11 as the virtual temperature parameter corresponding to the drum to facilitate subsequent adjustment of the temperature control device in combination with this parameter.

[0128] In summary, by adopting the method of calculating the temperature rise value to determine the virtual temperature parameter corresponding to the drum, the temperature rise rate of the drum is characterized by the temperature rise value, so as to facilitate subsequent adjustment of the temperature control device in combination with the temperature rise value, and ensure that the food materials in the drum can be heated evenly.

[0129] In addition, in order to accurately determine the highest temperature value as the virtual temperature parameter from each temperature data group, the virtual temperature parameter can also be determined by calculating the target temperature rise parameter corresponding to each group of temperature data. In this embodiment, the specific implementation method is as follows:

[0130] When there are multiple sets of the temperature data, read the historical temperature data corresponding to the temperature data, and calculate the temperature rise rate corresponding to each set of temperature data based on the temperature data and the historical temperature data; calculate the target temperature rise parameter according to the temperature rise rate corresponding to each set of temperature data and its corresponding temperature weight; determine the target temperature data set based on the target temperature rise parameter, and use the highest temperature value corresponding to the target temperature data set as the virtual temperature parameter.

[0131] Specifically, the historical temperature data specifically refers to the temperature data that has been stored before the temperature data, and there is a one-to-one correspondence between the historical temperature data and the temperature values in the temperature data set. That is to say, the temperature values with a corresponding relationship are the temperature values collected by the same temperature acquisition device in different time periods. Correspondingly, the temperature rise rate represents the temperature increase rate corresponding to each set of temperature data. Correspondingly, the target temperature rise parameter specifically refers to the value obtained by multiplying the temperature rise rate corresponding to each set of temperature data by the corresponding weight. Through the target temperature rise parameter, it can be determined whether each set of temperature data can represent the actual temperature of the drum.

[0132] Based on this, when there are multiple sets of temperature data, in order to determine the target temperature data set from them and select the corresponding highest temperature value as the virtual temperature parameter of the drum, during the screening process, the historical temperature data corresponding to the temperature data can be read, and then the temperature rise rate corresponding to each set of temperature data can be calculated by combining the temperature data and its corresponding historical temperature data. Then, in the order of the temperature rise rate from large to small, a temperature weight is assigned to each set of temperature data, and the greater the temperature rise rate, the greater the weight; then calculate the product of the temperature rise rate and the weight to obtain the target temperature rise parameter corresponding to each set of temperature data; finally, compare the target temperature rise parameters again, select the temperature data set corresponding to the highest target temperature rise parameter as the target temperature data set, and use the highest temperature value it contains as the virtual temperature parameter of the drum.

[0133] In practical applications, the size of the temperature weight can be set according to the actual application scenario, and this embodiment does not make any limitation here. Correspondingly, the process of calculating the temperature rise rate based on the temperature data and the historical temperature data is similar to the process of calculating the temperature rise value described above, and this embodiment will not elaborate too much here.

[0134] For example, according to the first set of temperature data and its corresponding historical temperature data, the temperature rise rate of this set is determined to be V1; according to the second set of temperature data and its corresponding historical temperature data, the temperature rise rate of this set is determined to be V2; according to the third set of temperature data and its corresponding historical temperature data, the temperature rise rate of this set is determined to be V3; where V1 > V2 > V3. At this time, a weight Q1 is assigned to the first set of temperature data, a weight Q2 is assigned to the second set of temperature data, and a weight Q3 is assigned to the third set of temperature data. By calculating the product of each set of temperature data and its corresponding weight, according to the calculation results, the target temperature rise parameter corresponding to the first set of temperature data is determined to be M1, the target temperature rise parameter corresponding to the second set of temperature data is determined to be M2, and the target temperature rise parameter corresponding to the third set of temperature data is determined to be M3. Then, the three are compared, and it is determined that the target temperature rise parameter M2 of the second set of temperature data is the largest, so the highest temperature value T in the second set of temperature data is selected. 2-2 As the virtual temperature parameter corresponding to the drum, it is convenient to adjust the temperature control device in combination with this parameter later.

[0135] It should be noted that after determining the target temperature data set, the temperature average value of the target temperature data set, the temperature value corresponding to the target time node, or the highest temperature value corresponding to the target time interval can also be selected as the virtual temperature parameter corresponding to the drum. In specific implementation, it can be selected according to actual needs, and this embodiment does not make any limitation here.

[0136] In summary, by using a weighted method to determine the target temperature data set and taking the highest temperature value corresponding to it as the virtual temperature parameter of the drum, it can ensure that the actual temperature of the drum is accurately reflected by the highest temperature value, improve the accuracy of adjusting the temperature control device later, and ensure better cooking effects.

[0137] In addition, it should be noted that when there is only temperature data feedback from one temperature acquisition device in a set of temperature data, then only the temperature data feedback from this temperature acquisition device is used as the basis for calculating the virtual temperature parameter corresponding to the drum. The specific calculation process can refer to the description of the virtual temperature parameter in the above embodiment, and this embodiment will not elaborate here.

[0138] Step S506, determine the power adjustment range corresponding to the virtual temperature parameter, and select the device adjustment strategy associated with the power adjustment range.

[0139] Specifically, after determining the virtual temperature parameter corresponding to the drum, further, in order to be able to accurately adjust the temperature control device based on the virtual temperature parameter to meet the cooking requirements of the current cooking environment, the power adjustment range corresponding to the virtual temperature parameter can be determined first, and then the device adjustment strategy associated with the power adjustment range is selected, so as to complete the adjustment of the temperature control device in combination with this strategy later.

[0140] Among them, the power adjustment range specifically refers to the power adjustment range set by the user in the current cooking environment or the adjustment range determined according to the recipe entered by the user; and the power adjustment range corresponds to the maximum and minimum values of power adjustment, which are used to limit the power so that it will not be too high or too low to affect the cooking effect. At the same time, the maximum and minimum values of power in the power adjustment range will respectively correspond to virtual temperature parameters, that is, the maximum value of power in the power adjustment range corresponds to a temperature value or a temperature rise value, and the minimum value of power corresponds to a temperature value or a temperature rise value.

[0141] That is to say, after determining the virtual temperature parameter, first determine the power adjustment range corresponding to the virtual temperature parameter based on the power adjustment range set by the user or the adjustment range determined according to the entered recipe, and then compare the virtual temperature parameter with the virtual temperature parameters corresponding to the maximum / minimum values of power in different power adjustment ranges according to the device adjustment strategy, so as to determine how to adjust the temperature control device.

[0142] Correspondingly, the device adjustment strategy specifically refers to the strategy used to adjust the temperature control device. Through this strategy, the way and result of adjusting the temperature control device can be determined, so as to realize the dynamic control of the temperature control device to stably heat the ingredients in the drum.

[0143] Furthermore, before determining the power adjustment range corresponding to the virtual temperature parameter, considering that the temperature of the drum at the current moment may be the best choice for heating, and any further adjustment may cause problems such as insufficient heating or overheating, which will lead to poor cooking of the ingredients. Therefore, after determining the virtual temperature parameter of the drum, it can be decided whether to adjust the temperature control device by means of judgment. In this embodiment, the specific implementation method is as follows:

[0144] When the virtual temperature value in the virtual temperature parameter reaches the preset first adjustment node, detect whether the virtual temperature rise value in the virtual temperature parameter reaches the preset second adjustment node;

[0145] If so, execute the step of determining the power adjustment range corresponding to the virtual temperature parameter;

[0146] If not, do not adjust the temperature control device and continue to collect temperature.

[0147] Specifically, the first adjustment node specifically refers to a threshold value set based on the temperature value, and the second adjustment node specifically refers to a threshold value set based on the temperature rise value. That is to say, in order to accurately determine whether the temperature control device needs to be adjusted, it can be determined by judging separately through the temperature dimension and the temperature rise dimension. That is, first determine the virtual temperature value corresponding to the drum, and then compare the virtual temperature value corresponding to the drum with the preset first adjustment node. If the first adjustment node is reached, then detect whether the virtual temperature rise value of the drum reaches the second adjustment node. If the second adjustment node is reached, then execute step S506 to achieve the subsequent adjustment of the temperature control device.

[0148] Furthermore, it is also possible to determine whether to adjust the temperature control device through one dimension, that is, to detect whether the virtual temperature value of the drum reaches the first adjustment node. If it reaches, then execute step S506. Or detect whether the virtual temperature rise value of the drum reaches the second adjustment node. If it reaches, then execute step S506. In actual applications, the specific judgment process can be implemented in any combination according to the actual application scenario, and this embodiment does not make too many limitations here.

[0149] In addition, in order to ensure that the adjusted temperature control device can maintain stable temperature and improve the cooking effect, it is also possible to record multiple virtual temperature parameters at the same time and calculate the numerical change rate of the virtual temperature parameters. When the temperature value or the temperature rise value of the drum is within a certain set range and the change rate approaches a flat value, then select the device adjustment strategy to adjust the output power of the temperature control device.

[0150] Step S508, adjust the above-mentioned temperature control device according to the device adjustment strategy.

[0151] Specifically, after determining the device adjustment strategy based on the virtual temperature parameters, further, the temperature control equipment can be adjusted according to the device adjustment strategy, so as to achieve the adjustment of the output power of the heating component in the temperature control equipment, or the dynamic adjustment of the rotation speed of the drum, ensuring that the ingredients in the drum are evenly heated and meeting the requirements of the current cooking environment, so as to achieve a better taste of the cooked food.

[0152] Furthermore, when adjusting the temperature control device according to the equipment adjustment strategy, in order to ensure that the ingredients can be evenly heated and will not lose their taste due to too high or too low temperature, it is possible to realize real-time adjustment by combining the upper / lower limit parameters of the power adjustment range when adjusting the temperature control device. In this embodiment, the specific implementation method is as follows:

[0153] (1) In the case where the virtual temperature parameter is greater than the upper limit parameter of the power adjustment range, turn off the temperature control device according to the device adjustment strategy.

[0154] Specifically, the upper limit parameter specifically refers to the upper limit temperature value or the upper limit temperature rise value corresponding to the maximum power value in the power adjustment range. Based on this, when the virtual temperature parameter is greater than the upper limit parameter, it indicates that the temperature of the drum at the current moment is too high and has exceeded the maximum value for cooking ingredients. If heating continues or rapid cooling cannot be achieved in a short time, it may cause damage to the ingredients. Therefore, when the virtual temperature parameter is greater than the upper limit parameter, the temperature control device can be immediately turned off, that is, the heating component is stopped from continuing to heat the drum. After the temperature of the drum drops below the upper limit temperature value or the temperature rise value of the drum drops below the upper limit temperature rise value, heating can be resumed.

[0155] In practical applications, when the virtual temperature parameter is a temperature value, the temperature value is compared with the upper limit temperature value; when the virtual temperature parameter is a temperature rise value, the temperature rise value is compared with the upper limit temperature rise value.

[0156] Continuing with the above example, when it is determined that the virtual temperature parameter of the drum is k2, the virtual temperature parameter k2 is compared with the upper limit temperature rise value k max of the power adjustment range. If the virtual temperature parameter k2 of the drum at the current moment is greater than the upper limit temperature rise value k max , it indicates that the temperature of the drum at the current moment is too high. At this time, the heating component in the temperature control device can be immediately turned off to stop heating the drum. And after the virtual temperature parameter of the drum drops below the upper limit temperature rise value k max , heating can be resumed.

[0157] In summary, stopping the operation of the temperature control device when it is greater than the upper limit parameter can achieve the effect of overheat protection, thereby avoiding the problem of damage to the ingredients in the drum due to excessive temperature. At the same time, it can play a safety protection role and avoid safety accidents caused by long-term heating.

[0158] (2) When the virtual temperature parameter is less than the lower limit parameter of the power adjustment range, determine the target temperature value based on the device adjustment strategy, and increase the output power of the temperature control device according to the target temperature value.

[0159] Specifically, the lower limit parameter specifically refers to the lower limit temperature value or the lower limit temperature rise value corresponding to the minimum power value in the power adjustment range. Correspondingly, the target temperature value specifically refers to the lowest temperature value for heating the drum, and only when it is higher than the target temperature value can it be ensured that the ingredients are heated sufficiently.

[0160] Based on this, when the virtual temperature parameter is less than the lower limit parameter, it indicates that the temperature of the drum at the current moment is too low to sufficiently heat the ingredients in the drum. If the temperature is not quickly increased or continues to decrease, it may cause the ingredients to fail to meet the edible requirement standards. Therefore, when the virtual temperature parameter is less than the lower limit parameter, the target temperature value can be determined according to the device adjustment strategy first, and then the output power of the temperature control device can be increased according to the target temperature value, that is, the output power of the heating component in the temperature control device is adjusted, so that the heating component can raise the temperature of the drum above the target temperature value and not exceed the upper limit temperature value, enabling the ingredients in the drum to be heated sufficiently without affecting their edibility after cooking.

[0161] In practical applications, when the virtual temperature parameter is a temperature value, the temperature value is compared with the lower limit temperature value; when the virtual temperature parameter is a temperature rise value, the temperature rise value is compared with the lower limit temperature rise value.

[0162] Continuing with the above example, when it is determined that the virtual temperature parameter of the drum is k2, the virtual temperature parameter k2 is compared with the lower limit temperature rise value k min of the power adjustment range. If the virtual temperature parameter k2 of the drum at the current moment is less than the lower limit temperature rise value k min , it indicates that the temperature of the drum at the current moment is too low, and at this time, the output power of the heating component in the temperature control device needs to be increased. Based on this, first, the target temperature value k corresponding to the currently heated ingredients is determined according to the device adjustment strategy, and then the output power of the heating component is adjusted upward according to the target temperature value, so that the heating component can heat the temperature of the drum above the target temperature value, which also means that the temperature rise value of the heated drum is greater than the lower limit temperature rise value k min and does not exceed the upper limit temperature rise value k max to achieve sufficient heating of the ingredients and ensure that the ingredients can be normally eaten after heating.

[0163] In summary, when it is less than the lower limit parameter, the target temperature value can be determined based on the device adjustment strategy, and based on this, the output power of the temperature control device is adjusted, so as to ensure that the ingredients in the drum can be heated sufficiently, ensure that the ingredients after heating can be eaten, and meet the user's edible requirements.

[0164] (3) When the virtual temperature parameter is less than or equal to the upper limit parameter and greater than or equal to the lower limit parameter, the output power of the temperature control device is decreased according to the device adjustment strategy.

[0165] Specifically, when the virtual temperature parameter is less than or equal to the upper limit parameter and greater than or equal to the lower limit parameter, it indicates that the temperature value or temperature rise value of the drum at the current moment is between the upper limit temperature value and the lower limit temperature value, or between the upper limit temperature rise value and the lower limit temperature rise value. This further indicates that the temperature of the drum at the current moment can be used for normal cooking. During this process, considering that if the output power of the heating component is not adjusted, the actual temperature of the drum may gradually rise over time and eventually exceed the upper limit parameter. At this time, adjusting the power will cause the fluctuation range of the output power of the heating component to be too large, which will have a greater impact on the cooking texture of the food ingredients.

[0166] In view of this, when the virtual temperature parameter is between the upper limit parameter and the lower limit parameter, the output power of the heating component can be gradually decreased according to the device adjustment strategy, and the decrease value in each cycle is not equal. It is ensured that the power is decreased quickly when approaching the upper limit parameter and decreased slowly when approaching the lower limit parameter, so as to ensure that the output power of the heating component can maintain the virtual temperature parameter of the drum between the upper limit parameter and the lower limit parameter in the power adjustment range for a long time during cooking, ensuring sufficient heating of the food ingredients without causing damage to the food ingredients.

[0167] Furthermore, when decreasing the output power of the temperature control device according to the device adjustment strategy, in order to meet the requirements of dynamic adjustment and not affect the cooking cycle of the food ingredients due to too large an adjustment amplitude, the adjustment can be carried out in a hierarchical manner. In this embodiment, the specific implementation method is as follows:

[0168] Determine the power adjustment level corresponding to the temperature control device based on the device adjustment strategy; determine the power adjustment value corresponding to the power adjustment level, and decrease the output power of the temperature control device according to the power adjustment value; wherein, the adjusted output power of the temperature control device is not less than the lower limit power corresponding to the lower limit parameter.

[0169] Specifically, the power adjustment level specifically refers to the level of the magnitude of power adjustment. The higher the power adjustment level, the greater the corresponding power adjustment value, indicating a larger span when decreasing the output power of the temperature control device; conversely, the lower the power adjustment level, the smaller the corresponding power adjustment value, indicating a smaller span when decreasing the output power of the temperature control device.

[0170] It should be noted that the closer the virtual temperature parameter at the current moment is to the upper limit parameter, the greater the corresponding power adjustment level; conversely, the closer the virtual temperature parameter is to the lower limit parameter, the smaller the corresponding power adjustment level. Among them, the power adjustment values corresponding to each power adjustment level are not equal, and the power adjustment values corresponding to each level are set in a gradually decreasing manner.

[0171] Based on this, after determining the device adjustment strategy corresponding to the virtual temperature parameter, the power adjustment level corresponding to the temperature control device can be determined according to the device adjustment strategy, then the power adjustment value corresponding to the power adjustment level can be determined, and finally the output power of the temperature control device can be lowered according to the power adjustment value, so as to maintain the temperature of the drum within a relatively stable range that can heat the food materials, avoiding insufficient heating of the food materials and damage to the food materials at the same time. During specific implementation, to ensure sufficient heating of the food materials in the drum, the adjusted output power can be set to be not less than the lower limit power corresponding to the lower limit parameter.

[0172] Continuing with the above example, it is determined that the virtual temperature parameter of the drum is k2, and the virtual temperature parameter k2 is located between the lower limit temperature rise value k min and the upper limit temperature rise value k max . In order to fully heat the food materials in the drum without overheating, and maintain the temperature of the drum within a set range, the device adjustment strategy determined based on the virtual temperature parameter k2 can be combined with the device adjustment strategy to determine the power adjustment level at the current moment; finally, the power adjustment value corresponding to this level can be determined, and the output power of the temperature control device can be lowered according to this power adjustment value, so that after the adjusted temperature control device heats the drum, the temperature rise value of the drum is not less than the lower limit temperature rise value k min That's it.

[0173] In summary, determining the power adjustment value according to the level and combining the power adjustment value to lower the output power of the temperature control device can ensure that the effect of cooking food materials is not affected by irregular adjustment of the output power.

[0174] In addition, considering the characteristics of the drum cooking system, it heats the food materials in the drum by rotating; based on this characteristic, in order to ensure uniform heating of the food materials in the drum, increase the number of times the food materials contact the heating surface of the drum, and improve the taste of the cooked food materials, the heat conduction effect can also be improved by adjusting the rotation speed of the drum and / or the pose of the work station. In this embodiment, the specific implementation method is as follows:

[0175] The temperature control device further includes a work station; correspondingly, adjusting the temperature control device according to the device adjustment strategy includes: adjusting the rotation speed of the drum and / or the pose of the work station according to the device adjustment strategy; when the adjusted temperature control device does not meet the preset heating condition, adjusting the output power of the heating component in the temperature control device.

[0176] Specifically, the working station specifically refers to the mechanism that can change the pose of the drum. By changing the pose of the working station, the contact times between the food materials in the drum and the inner wall of the drum can be controlled, as well as the heating range of the drum, so as to achieve the purpose of adjusting the temperature control equipment. Correspondingly, the preset heating condition specifically refers to the heating condition of the heating component in the temperature control device for the drum. That is to say, after adjusting the rotation speed and / or pose, if the virtual temperature parameter corresponding to the drum heated by the heating component is within the power adjustment range at this time, the power adjustment can be postponed to the next stage, and whether to adjust the output power will be determined according to the virtual temperature parameter of the drum in the next stage. If the virtual temperature parameter of the drum is not within the power adjustment range at this time, the power needs to be directly adjusted at this stage to ensure that the heat conduction, heat dissipation or heat transfer of the drum meets the requirements.

[0177] Furthermore, adjusting the rotation speed of the drum includes increasing the speed and decreasing the speed. Increasing or decreasing the speed can change the contact times between the food materials and the inner wall of the drum. Adjusting the pose of the working station includes laying the working station flat and raising the working station, so as to achieve the purpose of effective heat conduction, heat transfer and heat dissipation.

[0178] In practical applications, the food materials in the drum actually move synchronously relative to the inner wall of the drum. After the food materials in the drum are stirred, they will fall back into the heating area at the bottom of the drum again. At this time, as long as the speed is increased or decreased, the contact times between the food materials and the heating surface of the drum per unit time can be controlled. Under the condition of a certain power, the purpose of effective heat conduction, heat transfer and heat dissipation can be achieved. At the same time, changing the pose of the working station can be adjusted synchronously to avoid some heating areas not being covered by the food materials.

[0179] Based on this, when adjusting the temperature control device according to the device adjustment strategy, if the output power corresponding to it needs to be decreased at the current moment, the rotation speed of the drum can be increased and / or the working station can be laid flat first. If the adjusted temperature control device still does not meet the preset heating condition, the output power of the heating component in the temperature control device can be decreased according to the requirements. If the output power corresponding to it needs to be increased at the current moment, the rotation speed of the drum can be decreased and / or the working station can be raised first. If the adjusted temperature control device still does not meet the preset heating condition, the output power of the heating component in the temperature control device can be increased according to the requirements.

[0180] In addition, when adjusting the output power of the temperature control device, in order to quickly complete the power control, it can also be achieved by combining the power adjustment, the rotation speed adjustment of the drum and the pose adjustment of the working station at the same time. It is also possible to select one method for priority adjustment alone, and then select the next method to continue the adjustment when the heating condition cannot be met after the adjustment, until the heating condition is met. In practical applications, the adjustment methods of the temperature control device can be combined according to the actual application scenarios, and this embodiment does not make any limitations here.

[0181] In summary, by adjusting the rotation speed of the drum and / or the pose of the work station to control the number of contacts between the food ingredients and the inner wall of the drum and to control the coverage area of the food ingredients, the cooking effect of the food ingredients can be further improved, and the taste of the food ingredients will not be affected by the random change of power, further improving the user experience.

[0182] When adjusting the output power of the heating component in the temperature control device in the temperature control method provided in this embodiment, in order to ensure that the adjusted power meets the cooking requirements and does not affect the cooking effect of the food ingredients due to irregular power changes, after obtaining the temperature data collected by the temperature acquisition device according to the set time period, the virtual temperature parameter corresponding to the drum can be calculated based on the temperature data to represent the actual temperature parameter of the drum through the virtual temperature parameter; then, determine the power adjustment area corresponding to the virtual temperature parameter, select the device adjustment strategy associated with the power adjustment interval, and finally adjust the temperature control device according to the device adjustment strategy; it can be realized that the output power of the temperature control device can be dynamically adjusted in combination with the virtual temperature parameter of the drum, ensuring that the adjusted output power is more suitable for the cooking requirements of the current environment, cooking food with better taste, and improving the user experience.

[0183] The above is a schematic solution of a temperature control method in this embodiment. It should be noted that the technical solution of this temperature control method and the technical solution of the above temperature control device belong to the same concept. For the details not described in detail in the technical solution of the temperature control method, reference can be made to the description of the technical solution of the above temperature control device, and the two can refer to each other.

[0184] The following combines the attached Figure 6 , taking the application of the temperature control method provided in this specification in the stir-frying scenario as an example, to further illustrate the temperature control method. Among them, Figure 6 FIG. shows a processing flowchart of another temperature control method provided in an embodiment of this specification, which specifically includes the following steps:

[0185] Step S602, obtain three groups of temperature data collected by the temperature sensor within a preset time period.

[0186] Step S604, respectively determine the highest temperature value corresponding to each time node within the time period for each group of temperature data.

[0187] Step S606, calculate the temperature rise value between any two adjacent time nodes based on the highest temperature value.

[0188] Step S608, calculate the average temperature rise value corresponding to each group of temperature data according to the temperature rise value between any two adjacent time nodes.

[0189] Step S610, compare the average temperature rise with a preset temperature rise threshold, and select the temperature data group greater than the temperature rise threshold as the initial temperature rise data group.

[0190] Step S612, compare the average temperature rise corresponding to each initial temperature rise data group, and select the initial temperature rise data group with the highest average temperature rise as the target temperature rise data group.

[0191] Step S614, select the average temperature rise and the highest temperature value corresponding to the target temperature rise data group to form the virtual temperature parameter of the drum.

[0192] Step S616, detect whether the highest temperature value in the virtual temperature parameter reaches the first preset adjustment node; if so, execute step S618; if not, return to execute step 602 to re-perform temperature acquisition and temperature control in the next cycle.

[0193] Step S618, detect whether the average temperature rise in the virtual temperature parameter reaches the second preset adjustment node; if so, execute step S620; if not, return to execute step 602 to re-perform temperature acquisition and temperature control in the next cycle.

[0194] Step S620, determine the power adjustment range corresponding to the virtual temperature parameter, and select the device adjustment strategy associated with the power adjustment range.

[0195] Step S622, in the case where the highest temperature value in the virtual temperature parameter is greater than the upper limit parameter of the power adjustment range, turn off the temperature control device according to the device adjustment strategy.

[0196] Step S624, in the case where the highest temperature value in the virtual temperature parameter is less than the lower limit parameter of the power adjustment range, determine the target temperature value based on the device adjustment strategy, and increase the output power of the heating component in the temperature control device according to the target temperature value.

[0197] Step S626, in the case where the highest temperature value in the virtual temperature parameter is between the upper limit parameter and the lower limit parameter, increase the rotation speed of the drum and level the working position according to the device adjustment strategy, determine the power adjustment level corresponding to the temperature control device, and decrease the output power of the heating component in the temperature control device according to the power adjustment value corresponding to the power adjustment level.

[0198] In summary, by dynamically adjusting the output power of the temperature control device in combination with the virtual temperature parameter of the drum, it is ensured that the adjusted output power is more suitable for the cooking requirements of the current environment, cooking food with a better taste, and improving the user experience; at the same time, in combination with the heat transfer characteristics of the drum, the heating component and the ingredients, the purpose of the drum heat dissipation is still achieved by the heat transfer of the ingredients as much as possible during the high-temperature stage. Therefore, during the high-temperature stage of the drum, a relatively large power can still be applied, which not only improves the heat transfer efficiency but also protects the equipment from overheating, and better meets the user's needs.
