Description

Technical Field

[0001] This invention relates to the field of cooking appliance heating technology, and in particular to a heating control method, device, cooking appliance, and storage medium. Background Technology

[0002] When using cooking appliances (such as electric slow cookers), the food is usually placed in the pot, and then the pot is placed on the heating plate. The food is cooked by heating the bottom of the pot through the heating plate. Currently, electric slow cookers usually use ceramic pots. However, ceramic has low thermal conductivity. Therefore, when the heated part of the ceramic pot, such as the bottom, heats up rapidly, the heat cannot be transferred to the side walls of the ceramic pot in time. This creates a large temperature difference between the bottom and the sides, which can cause the pot to crack during the heating process, affecting the performance of the cooking appliance. Summary of the Invention

[0003] The main objective of this invention is to provide a heating control method, device, cooking appliance, and storage medium, which aims to solve the problem of existing cooking appliances easily cracking during cooking.

[0004] To achieve the above objectives, the present invention proposes a heating control method for a cooking appliance, the cooking appliance comprising a main body, a ceramic pot, a bottom heating device, a side heating device, a bottom temperature detection device, and a side temperature detection device, the control method of the cooking appliance comprising the following steps:

[0005] When the ceramic pot is placed in the mounting cavity of the main body and a heating command is received, the side heating device is first controlled to heat the side of the ceramic pot.

[0006] The bottom temperature of the ceramic pot is detected by the bottom temperature detection device, and the side temperature of the ceramic pot is detected by the side temperature detection device.

[0007] Based on the difference between the bottom temperature and the side temperature, the bottom heating device is controlled to turn on and operate.

[0008] In one embodiment, the bottom heating device and the side heating device are respectively provided for the bottom and side of the ceramic pot, so as to heat the bottom and side of the ceramic pot respectively;

[0009] The steps of controlling the bottom heating device to turn on and operate based on the difference between the bottom temperature and the side temperature include:

[0010] As the difference between the bottom temperature and the side temperature decreases, the heating power of the bottom heating device is increased in stages.

[0011] In one embodiment, the step of controlling the heating power of the bottom heating device to increase in stages during the process of the decrease in the difference between the bottom temperature and the side temperature includes:

[0012] When the difference is less than the first temperature difference threshold and greater than or equal to the second temperature difference threshold, the bottom heating device is controlled to heat the bottom of the ceramic pot with a first preset power, wherein the first temperature difference threshold is greater than the second temperature difference threshold.

[0013] When the difference is less than the second temperature difference threshold and greater than or equal to the third temperature difference threshold, the bottom heating device is controlled to heat the bottom of the ceramic pot with a second preset power, wherein the first preset power is less than the second preset power and the second temperature difference threshold is greater than the third temperature difference threshold.

[0014] When the difference is less than the third temperature difference threshold and greater than or equal to zero, the heating component is controlled to heat the bottom of the ceramic pot with a third preset power, wherein the second preset power is less than the third preset power.

[0015] In one embodiment, the step of controlling the bottom heating device to turn on based on the difference between the bottom temperature and the side temperature includes:

[0016] When the bottom temperature is lower than the side temperature and the difference is less than the first temperature difference threshold but greater than or equal to the second temperature difference threshold, the bottom heating device is turned on.

[0017] In one embodiment, the first temperature difference threshold is T1, wherein 27.5℃ < T1 ≤ 32.5℃; and / or,

[0018] The second temperature difference threshold is T2, wherein 17.5℃ < T2 ≤ 22.5℃; and / or,

[0019] The third temperature difference threshold is T3, where 7.5℃ < T3 ≤ 12.5℃.

[0020] In one embodiment, after the step of controlling the bottom heating device to turn on and operate based on the difference between the bottom temperature and the side temperature, the method includes:

[0021] When the bottom temperature exceeds the preset temperature, the bottom heating device is controlled to stop heating the bottom of the ceramic pot.

[0022] In one embodiment, the heating command includes a target heating duration;

[0023] After controlling the bottom heating device to turn on and operate based on the difference between the bottom temperature and the side temperature, the following steps are included:

[0024] When the actual heating time reaches the target heating time, the side heating device and the bottom heating device are controlled to stop heating.

[0025] The present invention also proposes a storage medium storing a heating control program, which, when executed by a processor, implements the above-described heating control method.

[0026] The present invention also proposes a control device for a cooking utensil, comprising:

[0027] A temperature detection module is used to acquire the side and bottom temperatures of the ceramic pot; and,

[0028] The heating control module is used to control the bottom heating device to turn on and operate based on the difference between the side temperature and the bottom temperature.

[0029] Furthermore, the present invention also proposes a cooking utensil, comprising:

[0030] main body;

[0031] A ceramic pot is placed in the main body;

[0032] A side heating device is provided on the main body for heating the side of the ceramic pot;

[0033] A bottom heating device is provided on the main body for heating the bottom of the ceramic pot;

[0034] A side temperature detection device is used to detect the side temperature of the ceramic pot;

[0035] A bottom temperature detection device is used to detect the bottom temperature of the ceramic pot;

[0036] A control device is electrically connected to the side heating device, the bottom heating device, the side temperature detection device, and the bottom temperature detection device. The control device includes a memory, a processor, and a heating control program for the cooking appliance stored in the memory and executable on the processor. The heating control program for the cooking appliance is configured to implement the steps of the heating control method for the cooking appliance described above.

[0037] In the technical solution of this invention, upon receiving a heating command, the side heating device is first controlled to heat the side of the ceramic pot to preheat it. The temperature difference between the bottom and side of the ceramic pot is determined by acquiring the bottom temperature and the side temperature. Simultaneously, based on this temperature difference, the bottom heating device is controlled to activate and operate. Thus, the temperature detection module acquires the side and bottom temperatures of the ceramic pot, and the heating control module controls the activation of the bottom heating device to preheat the side of the ceramic pot, ensuring its temperature is higher than its bottom temperature. Simultaneously, the bottom heating device is controlled to operate, controlling the temperature of the bottom of the ceramic pot to prevent excessively rapid temperature rise and a large temperature difference between the bottom and side during heating. This reduces the risk of cracking during heating, thus solving the problem of cracking in existing cooking utensils. Attached Figure Description

[0051] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the cooking utensil 100 involved in the embodiment of the present invention.

[0052] The cooking appliance 100 includes a main body 1, a ceramic pot 2, a side heating device 3, a bottom heating device 4, a side temperature detection device 5, and a bottom temperature detection device 6. The ceramic pot 2 is placed on the main body 1. The side heating device 3 is located on the main body 1 to heat the sides of the ceramic pot 2. The bottom heating device 4 is located on the main body 1 to heat the bottom of the ceramic pot 2. The side temperature detection device 5 is used to detect the side temperature of the ceramic pot 2, and the bottom temperature detection device 6 is used to detect the bottom temperature of the ceramic pot 2. A control device 7 is electrically connected to the side heating device 3, the bottom heating device 4, the side temperature detection device 5, and the bottom temperature detection device 6. Thus, through... The main body 1 is configured to house the ceramic pot 2, the side heating device 3, the bottom heating device 4, the side temperature detection device 5, the bottom temperature detection device 6, and the control device 7. The side heating device 3 and the bottom heating device 4 heat the bottom and sides of the ceramic pot 2 respectively. The side temperature detection device 5 and the bottom temperature detection device 6 detect the temperatures of the bottom and sides of the ceramic pot 2 respectively. The control device 7 controls the heating of the side heating device 3 and the bottom heating device 4 to prevent excessive temperature differences between the bottom and sides of the ceramic pot 2, thereby reducing the probability of the ceramic pot 2 cracking. Further, the cooking appliance 100 includes an electric slow cooker; however, in other embodiments, the cooking appliance 100 may also be an electric steamer, etc., and this invention is not limited to this.

[0053] Further, please refer to Figure 2 The control device 7 may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0054] like Figure 2 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a control program for the heating control device 7.

[0055] exist Figure 2 In the control device 7 shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the control device 7 of the present invention can be set in the control device 7. The control device 7 calls the heating control program of the control device 7 stored in the memory 1005 through the processor 1001 and executes the heating control method of the control device 7 provided in the embodiment of the present invention.

[0056] Those skilled in the art will understand that Figure 1 and Figure 2 The structure shown does not constitute a limitation on the cooking appliance 100, and may include more or fewer parts than shown, or combine certain parts, or have different arrangements of parts.

[0057] This invention provides a heating control method for a cooking appliance 100, referring to... Figure 3 , Figure 3 This is a schematic flowchart of the first embodiment of the heating control method for the cooking appliance 100 of the present invention.

[0058] In this embodiment, the cooking appliance 100 includes a main body 1, a ceramic pot 2, a bottom heating device 4, a side heating device 3, a bottom temperature detection device 6, and a side temperature detection device 5. The control method of the cooking appliance 100 includes the following steps:

[0059] Step S10: When the ceramic pot 2 is placed in the mounting cavity of the main body 1 and a heating command is received, the side heating device 3 is first controlled to heat the side of the ceramic pot 2.

[0060] Understandably, since cooking appliances 100 generally heat from the bottom, the bottom heating device 4 is the main heating device with higher power, while the side heating device 3 is an auxiliary heating device with lower power. During the operation of cooking appliances 100, the bottom of the ceramic pot 2 heats up relatively quickly, while the sides heat up relatively slowly. Therefore, upon receiving a heating command, the sides of the ceramic pot 2 are preheated first by heating the sides of the ceramic pot 2 through the side heating device 3.

[0061] Step S20: Obtain the bottom temperature of the ceramic pot 2 detected by the bottom temperature detection device 6 and the side temperature of the ceramic pot 2 detected by the side temperature detection device 5.

[0062] It is understood that the bottom temperature refers to the real-time temperature of the bottom of the ceramic pot 2 during the cooking process, and the side temperature refers to the real-time temperature of the side of the ceramic pot 2 during the cooking process. Furthermore, in order to obtain the bottom temperature and the side temperature, there are various ways to set the bottom temperature detection device 6 and the side temperature detection device 5. For example, they can be embedded in the bottom of the ceramic pot 2, or they can be set between the main body 1 and the ceramic pot 2, etc. The present invention does not limit this.

[0063] Step S30: Based on the difference between the bottom temperature and the side temperature, control the bottom heating device 4 to turn on and control the bottom heating device 4 to work.

[0064] It should be noted that the difference between the bottom temperature and the side temperature refers to the absolute difference between the bottom temperature and the side temperature. Specifically, if the bottom temperature is t1 and the side temperature is t2, and the difference is Δt, then Δt = |t1 - t2|. When the cooking appliance 100 starts heating, the side heating device 3 preheats the ceramic pot 2, so t2 > t1.

[0065] In this embodiment, upon receiving a heating command, the side heating device 3 is first controlled to heat the side of the ceramic pot 2 to preheat it. The temperature difference between the bottom and side of the ceramic pot 2 is determined by acquiring the bottom temperature and the side temperature. Simultaneously, based on this temperature difference, the bottom heating device 4 is activated. Thus, the temperature detection module acquires the side and bottom temperatures of the ceramic pot 2, and the heating control module controls the activation of the bottom heating device 4 to preheat the side of the ceramic pot 2, ensuring the side temperature is higher than the bottom temperature. Simultaneously, the bottom heating device 4 is activated to control the bottom temperature of the ceramic pot 2, preventing excessive temperature differences between the bottom and side during heating due to rapid bottom heating. This reduces the risk of the cooking appliance 100 cracking during heating, thus solving the problem of cracking in existing cooking appliances 100 during cooking.

[0066] Furthermore, the bottom heating device 4 and the side heating device 3 can be two heating components of the same heating element, or they can be two independently arranged heating elements; the present invention does not limit this. Specifically, in this embodiment, the bottom heating device 4 and the side heating device 3 are respectively arranged corresponding to the bottom and side of the ceramic pot 2, for heating the bottom and side of the ceramic pot 2 respectively.

[0067] It should be noted that the bottom heating device 4 and the side heating device 3 are two independent heating elements, so as to heat the bottom and side of the ceramic pot 2 respectively. Furthermore, the bottom heating device 4 and the side heating device 3 can be positioned in various ways. For example, they can be mounted on the main body 1, on the ceramic pot 2, or between the main body 1 and the ceramic pot 2, as long as they can heat the bottom and side of the ceramic pot 2 separately. This invention does not limit the specific placement of these elements.

[0068] Step S30 includes:

[0069] Step S31: During the process of the decrease in the difference between the bottom temperature and the side temperature, the heating power of the bottom heating device 4 is controlled to increase in stages.

[0070] It is understood that the heating power of the bottom heating device 4 can be fixed or adjustable. The present invention does not limit this. In this embodiment, the heating power of the bottom heating device 4 is adjustable. In addition, the bottom heating device 4 and the side heating device 3 are set separately so that the bottom heating device 4 and the side heating device 3 can maintain a certain distance to prevent local overheating of the ceramic pot 2.

[0071] In this embodiment, since the bottom heating device 4 has a large power, if the bottom heating device 4 uses a fixed power for heating during the heating process, the bottom temperature is likely to be too high, requiring frequent starting and stopping of the bottom heating device 4. This results in large temperature fluctuations in the cooking appliance 100, which is not conducive to cooking food in the cooking appliance 100. Therefore, as the difference between the bottom temperature and the side temperature decreases, the heating power of the bottom heating device 4 is controlled to increase in stages so that the bottom temperature of the ceramic pot 2 can rise slowly, allowing the heat from the bottom of the ceramic pot 2 to be transferred to the side in a timely manner. This can avoid excessive temperature difference between the bottom and the side of the ceramic pot 2, which helps to reduce the risk of cracking during heating, and can also reduce temperature fluctuations inside the cooking appliance 100, making it easier to control the temperature inside the cooking appliance 100.

[0072] Further, step S31 includes;

[0073] Step S311: When the difference is less than the first temperature difference threshold and greater than or equal to the second temperature difference threshold, control the bottom heating device 4 to heat the bottom of the ceramic pot 2 with a first preset power, wherein the first temperature difference threshold is greater than the second temperature difference threshold.

[0074] Understandably, the temperature difference between the bottom and sides of the pot is characterized by a first temperature difference threshold and a second temperature difference threshold. When the difference is greater than or equal to the first temperature difference threshold, it indicates that the temperature difference between the bottom and sides of the ceramic pot 2 is too large and exceeds the allowable range. When the difference is less than the first temperature difference threshold but greater than or equal to the second temperature difference threshold, it indicates that the temperature difference between the bottom and sides of the ceramic pot 2 is relatively large, but not yet exceeds the allowable range. Furthermore, since the heating power of the bottom heating device is much greater than that of the side heating device, even if the bottom heating device heats at a first preset power, the temperature rise rate of the bottom of the ceramic pot will be greater than that of its sides.

[0075] Step S312: When the difference is less than the second temperature difference threshold and greater than or equal to the third temperature difference threshold, control the bottom heating device 4 to heat the bottom of the ceramic pot 2 with a second preset power, wherein the first preset power is less than the second preset power and the second temperature difference threshold is greater than the third temperature difference threshold.

[0076] It is understandable that the temperature difference between the bottom and the side of the pot is characterized by the second temperature difference threshold and the third temperature difference threshold. When the difference is less than the second temperature difference threshold and greater than or equal to the third temperature difference threshold, it indicates that the temperature difference between the bottom and the side of the ceramic pot 2 is moderate.

[0077] Step S313: When the difference is less than the third temperature difference threshold and greater than or equal to zero, control the heating component to heat the bottom of the ceramic pot 2 with a third preset power, wherein the second preset power is less than the third preset power.

[0078] It is understood that when the difference is less than the third temperature difference threshold and greater than or equal to zero, it indicates that the temperature difference between the bottom and the side of the ceramic pot 2 is small.

[0079] In this embodiment, when the temperature difference is greater than or equal to the first temperature difference threshold, it indicates that the temperature difference between the bottom and side of the ceramic pot 2 is too large and exceeds the allowable range. At this time, the bottom heating device 4 is controlled to stop heating. When the temperature difference is less than the first temperature difference threshold and greater than or equal to the second temperature difference threshold, it indicates that the temperature difference between the bottom and side of the ceramic pot 2 is large, but has not yet exceeded the allowable range. At this time, the bottom heating device 4 is controlled to heat at a first preset power, that is, to heat at a lower power. When the temperature difference is less than the second temperature difference threshold and greater than or equal to the third temperature difference threshold, it indicates that the temperature difference between the bottom and side of the ceramic pot 2 is large, but has not yet exceeded the allowable range. At this time, the bottom heating device 4 is controlled to heat at a first preset power, that is, to heat at a lower power. When the temperature difference between the bottom and sides is moderate, the bottom heating device 4 is controlled to heat at a second preset power, i.e., at a moderate power. When the difference is less than the third temperature difference threshold and greater than or equal to zero, it indicates that the temperature difference between the bottom and sides of the ceramic pot 2 is small. In this case, the bottom heating device 4 is controlled to heat at a third preset power, i.e., at full power. Thus, the heating power of the bottom heating device 4 is adjusted according to the degree of temperature difference between the bottom and sides to control the temperature difference between the bottom and sides of the ceramic pot 2, which can prevent the difference from being too large and avoid excessive temperature fluctuations.

[0080] Furthermore, the step of controlling the bottom heating device 4 to turn on based on the difference between the bottom temperature and the side temperature includes:

[0081] Step S32: When the bottom temperature is lower than the side temperature and the difference is less than the first temperature difference threshold and greater than or equal to the second temperature difference threshold, control the bottom heating device 4 to turn on.

[0082] In this embodiment, the side of the ceramic pot 2 needs to be preheated before the bottom heating device 4 is turned on. The higher the preheating temperature of the side of the ceramic pot 2, the smaller the temperature difference between the bottom and the side of the ceramic pot 2 after the bottom heating device 4 is turned on. However, the higher the preheating temperature, the longer the heating time of the cooking appliance 100 will be. On the other hand, the greater the temperature difference between the bottom and the side of the ceramic pot 2 before the bottom heating device 4 is turned on, the higher the temperature difference between the bottom and the side of the ceramic pot 2 will be. Therefore, when the bottom temperature is lower than the side temperature and the difference is less than the first temperature difference threshold and greater than or equal to the second temperature difference threshold, it means that the temperature difference between the bottom and the side of the ceramic pot 2 has reached its limit and the preheating has been completed. At this time, controlling the bottom heating device 4 to turn on will not only help reduce the temperature difference between the bottom and the side of the ceramic pot 2 during subsequent heating, but also avoid the preheating time being too long.

[0083] Furthermore, the first temperature difference threshold, the second temperature difference threshold, and the third temperature difference threshold can be a fixed value or a range of values. This invention does not limit this. Specifically, in this embodiment, the first temperature difference threshold is T1, where 27.5℃ < T1 ≤ 32.5℃, and / or the second temperature difference threshold is T2, where 17.5℃ < T2 ≤ 22.5℃, and / or the third temperature difference threshold is T3, where 7.5℃ < T3 ≤ 12.5℃. This avoids excessive temperature difference between the bottom and sides of the ceramic pot 2 and allows the heating power of the bottom heating device 4 to be adjusted according to the degree of temperature difference between the bottom and sides, thereby facilitating the control of the temperature difference between the bottom and sides of the ceramic pot 2.

[0084] The heating process of cooking appliance 100 will be explained below using the above examples:

[0085] Specifically, when the ceramic pot 2 is placed in the mounting cavity of the main body 1 and a heating command is received, the side heating device 3 is first controlled to heat the side of the ceramic pot 2. During the operation of the side heating device 3, the bottom temperature t1 of the ceramic pot 2 detected by the bottom temperature detection device 6 and the side temperature t2 of the ceramic pot 2 detected by the side temperature detection device 5 are obtained. At the same time, based on the difference ΔT between the bottom temperature t1 and the side temperature t2, the bottom heating device 4 is controlled to turn on and operate. When t1 < T2 and T2 ≤ ΔT < T1, the bottom heating device 4 is turned on. As the difference between the bottom temperature and the side temperature decreases, the heating power of the bottom heating device 4 is controlled to increase in stages. When T2 ≤ ΔT < T1, the bottom heating device 4 heats at a first preset power, that is, the bottom heating device 4 uses low power for heating. When T3≤△T<T2, the bottom heating device 4 heats at a second preset power, i.e., the bottom heating device 4 uses medium power for heating. When 0≤△T<T3, the bottom heating device 4 heats at a third preset power, i.e., the bottom heating device 4 uses high power for heating. In this way, the temperature detection module can obtain the side temperature and bottom temperature of the ceramic pot 2, and the heating control module can control the bottom heating device 4 to preheat the side of the ceramic pot 2, so that the side temperature of the ceramic pot 2 is higher than its bottom temperature. At the same time, the bottom heating device 4 is controlled to work in order to control the temperature of the bottom of the ceramic pot 2, so as to avoid the temperature difference between the bottom and the side of the ceramic pot 2 being too large due to the bottom heating too quickly during the heating process. This reduces the risk of the cooking utensil 100 cracking during heating, thereby solving the problem that the existing cooking utensil 100 is prone to cracking during cooking.

[0086] Please see Figure 4 , Figure 4This is a schematic flowchart of the second embodiment of the heating control method for the cooking appliance 100 of the present invention.

[0087] Based on the first embodiment described above, after step S30, the following steps are included:

[0088] S40: When the bottom temperature is higher than the preset temperature, control the bottom heating device 4 to stop heating the bottom of the ceramic pot 2.

[0089] In the technical solution of this embodiment, when the bottom temperature is greater than the preset temperature, it means that although the temperature difference between the bottom temperature and the side temperature meets the requirements, the bottom temperature of the ceramic pot 2 is too high and high temperature protection treatment is required. At this time, the bottom heating device 4 is controlled to stop heating so that the bottom temperature of the ceramic pot 2 can be reduced to prevent the bottom of the ceramic pot 2 from overheating.

[0090] It should be noted that the preset temperature can be a fixed value or a range of values, etc., and the present invention does not limit it in this way. Specifically, taking a preset temperature of 200°C as an example, when the bottom temperature is greater than 200°C, it indicates that the bottom of the ceramic pot 2 is overheated. At this time, the bottom heating device 4 is controlled to stop heating.

[0091] Please see Figure 5 , Figure 5 This is a schematic flowchart of the third embodiment of the heating control method for the cooking appliance 100 of the present invention.

[0092] Based on the first embodiment described above, the heating command includes a target heating duration, and after step S30, the following is included:

[0093] S50: When the actual heating time reaches the target heating time, control the side heating device 3 and the bottom heating device 4 to stop heating.

[0094] In the technical solution of this embodiment, when the actual heating time reaches the target heating time, it indicates that cooking has ended. At this time, the bottom heating device 4 and the bottom heating device 4 stop heating simultaneously.

[0095] Furthermore, this embodiment of the invention also proposes a storage medium storing a control program for a cooking appliance 100. When the control program for the cooking appliance 100 is executed by a processor, it implements the heating control method for the cooking appliance 100 as described above.

[0096] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0097] Please see Figure 6 , Figure 6 This is a structural block diagram of the control device 7 of the cooking appliance 100 of the present invention in the first embodiment.

[0098] like Figure 6 As shown, the control device 7 of the cooking appliance 100 proposed in this embodiment of the invention includes:

[0099] Temperature detection module 10 is used to acquire the side temperature and bottom temperature of ceramic pot 2;

[0100] The heating control module 20 is used to control the bottom heating device 4 to turn on and operate based on the difference between the side temperature and the bottom temperature.

[0101] In this embodiment, upon receiving a heating command, the side heating device 3 is first controlled to heat the side of the ceramic pot 2 to preheat it. The temperature difference between the bottom and side of the ceramic pot 2 is determined by acquiring the bottom temperature and the side temperature. Simultaneously, based on this temperature difference, the bottom heating device 4 is activated. Thus, the temperature detection module acquires the side and bottom temperatures of the ceramic pot 2, and the heating control module controls the activation of the bottom heating device 4 to preheat the side of the ceramic pot 2, ensuring the side temperature is higher than the bottom temperature. Simultaneously, the bottom heating device 4 is activated to control the bottom temperature of the ceramic pot 2, preventing excessive temperature differences between the bottom and side during heating due to rapid bottom heating. This reduces the risk of the cooking appliance 100 cracking during heating, thus solving the problem of cracking in existing cooking appliances 100 during cooking.
