[0055] In some embodiments, the device body 4 has a cooking cavity for accommodating cooking ingredients.

[0056] In some embodiments, the input device 5 is used to receive configuration parameters set by the user, where the configuration parameters include the operating mode of the cooking device.

[0057] In some embodiments, the operation mode of the cooking device may include turning on the energy-saving mode and saving the relay, turning off the energy-saving mode and saving the relay, turning on the energy-saving mode and not saving the relay, or turning off the energy-saving mode and not saving the relay.

[0058] In some embodiments, the user may set configuration parameters of the cooking device through the input device 5. After the user sets the configuration parameters, the input device 5 receives the configuration parameters set by the user to determine the operation mode of the cooking device.

[0059] In some embodiments, the temperature sensor 6 is used to detect the real-time temperature value of the cooking cavity.

[0060] In some embodiments, the heating component 7 is used to provide heat to the cooking cavity to heat the cooking ingredients.

[0061] In the embodiment shown in the present application, the controller 1000 refers to a device that can generate an operation control signal based on an instruction operation code and a timing signal to instruct the cooking device 1 to execute a control instruction.

[0062] For example, the controller 1000 may be a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof.

[0064] In addition, the controller 1000 can be used to control various components inside the cooking device 1 so that each component operates to achieve various predetermined functions of the cooking device 1.

[0065] Figure 3 This is a hardware configuration block diagram of a cooking device provided by this application according to an exemplary embodiment. Figure 3 As shown, the cooking device 1 may further include a communication interface 1003 .

[0066] In some embodiments, the communication interface 1003 is used to establish a communication connection with other network entities, such as establishing a communication connection with a terminal device. The communication interface 1003 may include a radio frequency (RF) module, a cellular module, a wireless fidelity (WIFI) module, and a GPS module.

[0067] Those skilled in the art will understand that Figure 3 The hardware structure shown in the figure does not constitute a limitation on the cooking device. The cooking device 1 may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0068] Figure 4 A flow chart of a temperature control method provided in an embodiment of the present application is applied to the above-mentioned cooking equipment, such as Figure 4 As shown, the method includes the following steps:

[0069] S101: A controller obtains an operating mode of a cooking device.

[0070] Among them, the operating mode is an operating mode related to energy saving and / or relays, and the operating mode of the cooking equipment includes turning on the energy saving mode and saving the relay, turning off the energy saving mode and saving the relay, turning on the energy saving mode and not saving the relay, or turning off the energy saving mode and not saving the relay.

[0071] In some embodiments, the controller may obtain the operating mode of the cooking device set by the user through an input device of the cooking device.

[0072] Exemplarily, the input device can be a human-computer interaction interface, and the user can configure the cooking equipment parameters through the human-computer interaction interface of the cooking equipment; the input device can also be a human-computer interaction button, and the user can configure the cooking equipment parameters through the human-computer interaction button; the input device can also be a mobile terminal (such as a mobile phone, computer), and the user can configure the cooking equipment parameters through an application on the mobile terminal. This application does not limit the type of input device.

[0073] Furthermore, after the user sets the configuration parameters of the cooking device, the input device 5 receives the configuration parameters set by the user to determine the operation mode of the cooking device.

[0074] S102: The controller obtains the real-time temperature value of the cooking cavity in the current heating cycle.

[0075] Optionally, the controller may obtain a real-time temperature value of the cooking cavity in the current heating cycle through a temperature sensor.

[0076] The current heating cycle is any heating cycle among multiple heating cycles when the cooking device performs a cooking task.

[0077] It should be noted that whether the heating component is heated or not can be achieved by switching the relay. For example, when the relay is turned on, the heating component starts heating; when the relay is turned off, the heating component stops heating. The smaller the duty cycle of the relay in a heating cycle, the less resources are consumed, and the longer the relay can be used, that is, the longer its service life.

[0078] In some embodiments, the heating element performs heating in the current heating cycle according to the duty cycle of the current heating cycle.

[0079] The duty cycle of the current heating cycle is the ratio of the heating time of the cooking device in the current heating cycle to the total time of the current heating cycle.

[0080] For example, if the duty cycle of the current heating cycle is 0.5 and the total duration of the current heating cycle is 1 minute, the heating time of the heating component is 30 seconds; if the duty cycle of the current heating cycle is 0.7 and the total duration of the current heating cycle is 2 minutes, the heating time of the heating component is 84 seconds.

[0081] It should be noted that by controlling the heating component to heat in this way, the heating component of the cooking equipment can be turned on and off only once in each heating cycle of performing the cooking task, reducing the number of switching times of the relay in the heating component, thereby achieving the purpose of extending the service life of the relay.

[0082] S103: The controller inputs the operation mode and the real-time temperature value into the temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0083] The next heating cycle is a heating cycle that follows the current heating cycle and is adjacent to the current heating cycle, and the target duty cycle is a ratio of the heating duration of the heating component in the next heating cycle to the total duration of the next heating cycle.

[0084] Figure 5 A flow chart of a method for determining a target duty cycle provided in an embodiment of the present application is provided, which is used to determine the target duty cycle of the heating component in the next heating cycle, such as Figure 5 As shown, the method includes the following steps:

[0085] S1031. The controller obtains at least one temperature control model.

[0086] In some embodiments, the temperature control model includes at least one temperature control model.

[0087] Exemplarily, the temperature control model may include a first temperature control model, a second temperature control model, a third temperature control model, and a fourth temperature control model, and different operating modes of the cooking device correspond to different temperature control models.

[0088] S1032: The controller determines a target temperature control model from at least one temperature control model according to the operation mode and a preset corresponding relationship.

[0089] The preset corresponding relationship is used to indicate the corresponding relationship between at least one operating mode and at least one temperature control model.

[0090] Table 1 shows a correspondence table. As shown in Table 1, the correspondence table may include multiple operating modes and multiple temperature control models, and the multiple operating modes and the multiple temperature control models have a one-to-one correspondence.

[0091] Table 1

[0092] Operation mode Temperature control model Turn on energy saving mode and save relays First temperature control model Turn off energy saving mode and save relay Second temperature control model Turn on energy saving mode without saving relays The third temperature control model Turn off energy saving mode without saving relays Fourth temperature control model

[0093] Exemplarily, when the cooking device operates in energy-saving mode with the relays saved, the corresponding temperature control model is the first temperature control model; when the cooking device operates in energy-saving mode with the relays saved, the corresponding temperature control model is the second temperature control model; when the cooking device operates in energy-saving mode with the relays saved, the corresponding temperature control model is the third temperature control model; when the cooking device operates in energy-saving mode with the relays not saved, the corresponding temperature control model is the fourth temperature control model.

[0094] S1033: The controller inputs the operating mode and the real-time temperature value into the target temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0095] In some embodiments, if the cooking device operates in energy-saving mode and relay saving, the energy-saving mode and relay saving and the real-time temperature value are input into the first temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0096] In some embodiments, the first temperature control model can be trained using a reinforcement learning algorithm, such as a soft actor-critic (SAC) algorithm, a proximal policy optimization (PPO) algorithm, or a deep Q network (DQN) algorithm. This application does not limit the type of reinforcement learning algorithm used for the first temperature control model.

[0097] In some embodiments, the first temperature control model is trained using a reinforcement learning algorithm. First, the input parameters, output parameters, and preset energy-saving parameter values ​​(ie, maximum reward values) for training the first temperature control model are determined.

[0098] In some embodiments, assuming that the total duration of a heating cycle is 1 minute, the input parameters of the first temperature control model are the real-time temperature value inside the cooking wall detected by the temperature sensor every second in the previous heating cycle, the target temperature value, the energy-saving mode on (the corresponding value of the energy-saving mode on is 1) and the saving relay (the corresponding value of the saving relay is 1), and the output parameter is the duty cycle (Action) of the next heating cycle.

[0099] In some embodiments, the preset energy-saving parameter value is calculated as shown in formula (1):

[0100]

[0101] Among them, Reword is the energy-saving parameter value range, T sensor is the real-time temperature value, T target is the target temperature value, R max is the preset energy-saving parameter value (that is, the maximum value in the energy-saving parameter value range), Range is the temperature difference range between the real-time temperature value and the target temperature value, U1 is the energy-saving index, and Action is the duty cycle of the previous heating cycle.

[0102] In some embodiments, R max is a positive value (such as 1), the value of Range can be max Same, or greater than R max Here the user sets the energy saving mode to be turned on, so U1 is 1.

[0103] It can be seen from formula (1) that the greater the difference between the real-time temperature value of the cooking chamber and the target temperature value, the smaller the energy-saving parameter value; the greater the duty cycle, the smaller the energy-saving parameter value (that is, the longer the heating component is turned on, the smaller the energy-saving parameter value).

[0104] In some embodiments, a coefficient may be added to Action*U1 in formula (1), and the coefficient may determine the fluctuation range of the real-time temperature value of the cooking cavity when the energy-saving mode is turned on.

[0105] For example, the difference between the real-time temperature value detected by the temperature sensor at the current moment and the target temperature value may be replaced by the average temperature of the real-time temperature values ​​detected by the temperature sensor every second in any past cycle.

[0106] In some embodiments, in order to obtain a larger energy-saving parameter value after saving the relay during the temperature control process, if the user configures the relay to save and no relay switching operation is performed in the previous heating cycle (that is, Action is 0), then Reword is added with 1 or other positive numbers.

[0107] In some embodiments, after the preset energy-saving parameter value of the first temperature control model is determined, the energy-saving mode is turned on, the saving relay and the real-time temperature value are input into the first temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0108] In some embodiments, if the cooking device operates in an energy-saving mode with the energy-saving mode turned off and the relay saved, the energy-saving mode turned off and the relay saved and the real-time temperature value are input into the second temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0109] In some embodiments, the second temperature control model can be trained using a reinforcement learning algorithm, such as a soft actor-critic (SAC) algorithm, a proximal policy optimization (PPO) algorithm, or a deep Q network (DQN) algorithm. This application does not limit the type of reinforcement learning algorithm used for the second temperature control model.

[0110] In some embodiments, the second temperature control model is trained using a reinforcement learning algorithm. First, the input parameters, output parameters, and preset energy-saving parameter values ​​(ie, maximum reward values) for training the second temperature control model are determined.

[0111] In some embodiments, assuming that the total duration of a heating cycle is 1 minute, the input parameters of the first temperature control model are the real-time temperature value inside the cooking wall detected by the temperature sensor every second in the previous heating cycle, the target temperature value, turning off the energy-saving mode (the corresponding value of turning off the energy-saving mode is 0), and saving the relay (the corresponding value of saving the relay is 1), and the output parameter is the duty cycle (Action) of the next heating cycle.

[0112] Furthermore, after a heating cycle is completed, the real-time temperature value T detected by the temperature sensor is obtained. sensor , target temperature value T target , preset energy saving parameter value R max , the difference between the real-time temperature value and the target temperature value Range, the user turns on the energy-saving mode U1, and the duty cycle Action of the previous heating cycle.

[0113] In some embodiments, the preset energy-saving parameter value is calculated as shown in the above formula (1). Here, the user sets the energy-saving mode to be turned off, and U1 is 0.

[0114] In some embodiments, after the preset energy-saving parameter value of the second temperature control model is determined, the energy-saving mode is turned off, the saving relay and the real-time temperature value are input into the second temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0115] In some embodiments, if the cooking device operates in an energy-saving mode without saving relays, the energy-saving mode without saving relays and the real-time temperature value are input into the third temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0116] In some embodiments, the third temperature control model can be trained using a reinforcement learning algorithm, such as a soft actor-critic (SAC) algorithm, a proximal policy optimization (PPO) algorithm, or a deep Q network (DQN) algorithm. This application does not limit the type of reinforcement learning algorithm used for the third temperature control model.

[0117] In some embodiments, the third temperature control model is trained using a reinforcement learning algorithm. First, the input parameters, output parameters, and preset energy-saving parameter values ​​(ie, maximum reward values) for training the third temperature control model are determined.

[0118] In some embodiments, assuming that the total duration of a heating cycle is 1 minute, the input parameters of the first temperature control model are the real-time temperature value inside the cooking wall detected by the temperature sensor every second in the previous heating cycle, the target temperature value, the energy-saving mode on (the corresponding value of the energy-saving mode on is 1), and the relay not saving (the corresponding value of the relay not saving is 0), and the output parameter is the duty cycle (Action) of the next heating cycle.

[0119] Furthermore, after a heating cycle is completed, the real-time temperature value T detected by the temperature sensor is obtained. sensor , target temperature value T target , preset energy saving parameter value Rmax , the difference between the real-time temperature value and the target temperature value Range, the user turns on the energy-saving mode U1, and the duty cycle Action of the previous heating cycle.

[0120] In some embodiments, the preset energy-saving parameter value (ie, the maximum reward value) is calculated as shown in the above formula (1). Here, if the user sets the energy-saving mode to be turned on, U1 is 1.

[0121] In some embodiments, after the energy-saving parameter value of the third temperature control model is determined, the energy-saving mode is turned off, the saving relay and the real-time temperature value are input into the third temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0122] In some embodiments, if the cooking device operates in a mode of turning off the energy-saving mode and not saving the relay, the energy-saving mode and not saving the relay and the real-time temperature value are input into the fourth temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0123] In some embodiments, the fourth temperature control model can be trained using a reinforcement learning algorithm, such as a soft actor-critic (SAC) algorithm, a proximal policy optimization (PPO) algorithm, or a deep Q network (DQN) algorithm. This application does not limit the type of reinforcement learning algorithm used for the fourth temperature control model.

[0124] In some embodiments, the fourth temperature control model is trained using a reinforcement learning algorithm. First, the input parameters, output parameters, and preset energy-saving parameter values ​​(ie, maximum reward values) for training the fourth temperature control model are determined.

[0125] In some embodiments, assuming that the total duration of a heating cycle is 1 minute, the input parameters of the first temperature control model are the real-time temperature value of the cooking chamber detected by the temperature sensor every second in the previous heating cycle, the target temperature value, turning off the energy-saving mode (the value corresponding to turning off the energy-saving mode is 0), and not saving the relay (the value corresponding to not saving the relay is 0), and the output parameter is the duty cycle (Action) of the next heating cycle.

[0126] Furthermore, after a heating cycle is completed, the real-time temperature value T detected by the temperature sensor is obtained. sensor , target temperature value T target , preset energy saving parameter value R max , the difference between the real-time temperature value and the target temperature value Range, the user turns on the energy-saving mode U1, and the duty cycle Action of the previous heating cycle.

[0127] In some embodiments, the preset energy-saving parameter value is calculated as shown in the above formula (1). Here, the user sets the energy-saving mode to be turned off, and U1 is 0.

[0128] In some embodiments, after the energy-saving parameter value of the fourth temperature control model is determined, the energy-saving mode is turned off, the saving relay and the real-time temperature value are input into the fourth temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0129] S104: The controller controls the heating component to heat the cooking ingredients in the next heating cycle based on the target duty cycle.

[0130] In some embodiments, if the cooking device operates in energy-saving mode and saves relays, the controller adjusts the heating time of the heating component in the next heating cycle according to the target duty cycle output by the first temperature control model to control the real-time temperature value of the cooking cavity.

[0131] For example, if the target duty cycle output by the first temperature control model is 0.3 and the total duration of the next heating cycle is 1 minute, the heating component is controlled to turn on and continuously heat the cooking ingredients in the first 18 seconds of the next heating cycle and to turn off in the last 42 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 18 seconds of the next heating cycle and to turn off for the other 42 seconds.

[0132] In some embodiments, if the cooking device operates in an energy-saving mode with the energy-saving mode turned off and the relay saved, the controller adjusts the heating time of the heating component in the next heating cycle according to the target duty cycle output by the second temperature control model to control the real-time temperature value of the cooking cavity.

[0133] For example, if the target duty cycle output by the second temperature control model is 0.4 and the total duration of the next heating cycle is 1 minute, the heating component is controlled to turn on and continuously heat the cooking ingredients in the first 24 seconds of the next heating cycle and to turn off in the last 36 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 24 seconds of the next heating cycle and to turn off for the other 36 seconds.

[0134] In some embodiments, if the cooking device operates in energy-saving mode without saving relays, the controller adjusts the heating time of the heating component in the next heating cycle according to the target duty cycle output by the third temperature control model to control the real-time temperature value of the cooking cavity.

[0135] For example, if the target duty cycle output by the third temperature control model is 0.5 and the total duration of the next heating cycle is 1 minute, the heating component is controlled to turn on and continuously heat the cooking ingredients in the first 30 seconds of the next heating cycle and to turn off in the last 30 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 30 seconds of the next heating cycle and to turn off for the other 30 seconds.

[0136] In some embodiments, if the cooking device operates in an energy-saving mode that is turned off and does not save relays, the controller adjusts the heating time of the heating component in the next heating cycle according to the target duty cycle output by the fourth temperature control model to control the real-time temperature value of the cooking cavity.

[0137] For example, if the target duty cycle output by the fourth temperature control model is 0.6 and the total duration of the next heating cycle is 1 minute, the heating component is controlled to turn on and continuously heat the cooking ingredients in the first 36 seconds of the next heating cycle and to turn off in the last 24 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 36 seconds of the next heating cycle and to turn off for the other 24 seconds.

[0138] The technical solution provided by the embodiments of the present application brings at least the following beneficial effects: the technical solution calculates the target duty cycle of the heating component in the next heating cycle by using the acquired operating mode of the cooking device and the real-time temperature value of the cooking cavity in the current heating cycle as input parameters of the temperature control model, so that the calculation method of the target duty cycle is more accurate and more in line with the execution requirements of the cooking task. At the same time, the controller controls the heating component to heat the cooking ingredients in the next heating cycle based on the target duty cycle. This heating method can more accurately control the temperature in the cooking cavity.

[0139] In some embodiments, the above step S104 can also be performed by Figure 6 The method described is implemented, Figure 6 A flow chart of another temperature control method provided in an embodiment of the present application is shown as follows: Figure 6 As shown, the method includes the following steps:

[0140] S201: The controller determines the heating time of the heating component in the next heating cycle according to the target duty cycle.

[0141] In some embodiments, the target duty cycle of the next heating cycle is a ratio of the heating duration of the heating component in the next heating cycle to the total duration of the next heating cycle.

[0142] For example, if the target duty cycle of the next heating cycle is 0.3 and the total duration of the next heating cycle is 1 minute, the heating duration of the heating component in the next heating cycle is 18 seconds.

[0143] For another example, if the target duty cycle of the next heating cycle is 0.5 and the total duration of the next heating cycle is 1 minute, the heating duration of the heating component in the next heating cycle is 30 seconds.

[0144] S202. In the next heating cycle, the controller controls the heating component to continue heating the cooking ingredients after being turned on until the heating time is reached.

[0145] It should be noted that the heating duration of the heating component in the next heating cycle can be any duration in the next heating cycle, and this application does not limit the time period in which the heating duration of the heating component falls.

[0146] For example, if the heating time of the heating component in the next heating cycle is 18 seconds, the controller controls the heating component to turn on and continuously heat the cooking ingredients in the first 18 seconds of the next heating cycle and turn off in the last 42 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 18 seconds of the next heating cycle and turn off for the other 42 seconds.

[0147] For another example, if the heating time of the heating component in the next heating cycle is 30 seconds, the controller controls the heating component to turn on and continuously heat the cooking ingredients in the first 30 seconds of the next heating cycle and to turn off in the last 30 seconds. Alternatively, the controller controls the heating component to turn on and continuously heat the cooking ingredients in any 30 seconds of the next heating cycle and to turn off for the other 30 seconds.

[0148] It should be noted that, through the method provided in this embodiment, the heating component of the cooking device is turned on and off only once in each heating cycle of performing a cooking task, thereby avoiding frequent switching of the heating component and extending the service life of the heating component.

[0149] In some embodiments, the training method of the temperature control model in step S103 can also be performed as follows: Figure 7 The method described is implemented, Figure 7 A flow chart of another temperature control method provided in an embodiment of the present application is used to train a temperature control model, such as Figure 7 As shown, the method includes the following steps:

[0150] S301: The controller obtains a training sample set.

[0151] The training sample set includes multiple training samples, and the training samples include the operation mode of the cooking device in the historical heating cycle, the historical real-time temperature value, and the historical duty cycle of the heating component.

[0152] S302: The controller trains the initial temperature control model with preset energy-saving parameter values ​​according to the training sample set to obtain a temperature control model.

[0153] The energy-saving parameter value of the temperature control model is used to characterize the energy-saving degree of the cooking equipment under the operation mode of the historical heating cycle.

[0154] It should be noted that the specific training method of the temperature control model is detailed in the above step S103 and will not be repeated here.

[0155] In some embodiments, after the heating component controls the heating component to heat the cooking ingredients according to the target duty cycle of the next heating cycle, the controller can also determine whether to end the cooking task based on the actual cooking time and the target cooking time of the cooking device. Figure 8 A flow chart of another temperature control method provided in an embodiment of the present application is used to determine whether to end a cooking task, such as Figure 8 As shown, the method includes the following steps:

[0156] S401: The controller obtains the actual cooking time and the target cooking time of the cooking device.

[0157] Optionally, the controller may obtain the target cooking time set by the user through an input device.

[0158] In some embodiments, users can set a reasonable target cooking time based on their own needs or the type of cooking ingredients to ensure the final taste and maturity of the cooking ingredients.

[0159] S402: The controller determines whether to end the cooking task according to the actual cooking time and the target cooking time.

[0160] Figure 9 A flow chart of another temperature control method provided in an embodiment of the present application is provided, in which it is determined whether to end the cooking task, such as Figure 9 The method comprises the following steps:

[0161] S501: When the actual cooking time of the cooking device reaches the target cooking time, the controller controls the cooking device to end the cooking task.

[0162] For example, if the target cooking time input by the user is 3 minutes, and in the next heating cycle, the actual cooking time of the cooking device is 3 minutes, the controller controls the cooking device to end the cooking task.

[0163] S502: When the actual cooking time of the cooking device does not reach the target cooking time, the controller inputs the operation mode and the real-time temperature value into the temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0164] In some embodiments, in the current heating cycle, if the actual cooking time of the cooking device does not reach the target cooking time, the controller again obtains the operating mode of the cooking device and the real-time temperature value of the cooking cavity set by the user through the input device, and inputs the operating mode and real-time temperature value into the temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0165] It should be noted that the training method of the temperature control model is detailed in the above step S103 and will not be repeated here.

[0166] S503: The controller controls the heating component to heat the cooking ingredients in the next heating cycle based on the target duty cycle.

[0167] In some embodiments, the controller controls the heating component to heat the cooking ingredients in the next heating cycle based on the target duty cycle until the actual cooking time of the cooking device reaches the target cooking time.

[0168] It should be noted that the heating method of the heating component according to the target duty cycle is detailed in the above step S103 and will not be repeated here.

[0169] By using the above method, the number of switching times of the relay of the heating component can be reduced as much as possible (that is, the duty cycle of the heating cycle can be reduced), thereby increasing the closing time of the relay and extending the service life of the relay. Figure 10 A comparative bar chart of the proportion of relay closing time is provided for the embodiment of the present application, such as Figure 10 As shown in the figure, in the original temperature control method, the average ratio of the time the relay is closed to the heating cycle is 0.25. After the improvement of the above method, the average ratio of the time the relay is closed to the heating cycle is increased to 0.35, an increase of 40%, which effectively reduces the service life of the relay and thus extends the service life of the relay.

[0170] In some embodiments, the above steps S101 to S104 can also be performed as follows: Figure 11 The method described is implemented, Figure 11 A flow chart of another temperature control method provided in an embodiment of the present application is shown as follows: Figure 11 As shown, the method includes the following steps:

[0171] S11. The controller controls the cooking device to start executing the cooking task.

[0172] In some embodiments, the cooking task can be issued by the user or automatically selected by the cooking device based on the type of cooking ingredients. This application does not limit the method for obtaining the cooking task.

[0173] S12. The controller obtains the operation mode of the cooking device and the real-time temperature value of the cooking cavity set by the user in the current heating cycle.

[0174] In some embodiments, the controller may obtain the operating mode of the cooking device set by the user through an input device and obtain the real-time temperature value of the cooking cavity through a temperature sensor.

[0175] S13. The controller inputs the operation mode and real-time temperature value of the cooking device in the current heating cycle into the temperature control model to obtain the target duty cycle of the heating component in the next heating cycle.

[0176] The duty cycle of the heating component in the next heating cycle is the ratio of the heating time of the heating component in the next heating cycle to the total time of the next heating cycle.

[0177] S14: The controller controls the heating component to perform heating in the next heating cycle according to the target duty cycle.

[0178] S15. When the actual cooking time of the cooking device reaches the target cooking time, the controller controls the cooking device to end the cooking task; when the actual cooking time of the cooking device does not reach the target cooking time, execute the above step S12.
