[0048] In order to make the purposes, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0049] The cooking appliance control method provided by the embodiments of the present application is used to control a cooking appliance. The cooking appliance includes, but is not limited to, a rice cooker, a braising pot, an electric pressure cooker, etc. The structure of the cooking appliance is not unique. For example, the cooking appliance includes a pot body, an inner pot and a cover body. The pot body is used to accommodate the inner pot and heat the inner pot, so that the temperature of the food to be cooked in the inner pot is increased, and the food is cooked. The cover body is arranged on the pot body. When the cover body is closed, the cover body and the pot body form a cooking space, and the inner pot is in the cooking space. The pot body can have a general rectangular body shape with rounded corners, a general cylindrical shape or any other suitable shape. The inner pot has a general cylindrical shape or any other suitable shape.

[0050] The cooking appliance control method can be executed by a controller in the cooking appliance, or by a terminal or a server in communication connection with the cooking appliance. The terminal can be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The server can be a physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. Most of the following embodiments are described by taking the cooking appliance control method executed by the controller as an example.

[0051] In one example embodiment, a cooking appliance control method is provided. The cooking process of the cooking appliance includes a cooking mode determination stage, a soaking stage and a warming-up stage which are executed in sequence. The main purpose of the cooking mode determination stage is to detect the cooking mode of the cooking appliance. The main purpose of the soaking stage is to promote water absorption of the food to be cooked and facilitate the ripening of the food to be cooked. The main purpose of the warming-up stage is to raise the temperature of the inner pot so as to heat the food to be cooked in the inner pot and gradually raise the temperature of the food to be cooked to the boiling temperature. It can be understood that after the warming-up stage, there is a boiling stage. The main purpose of the boiling stage is to heat the food to be cooked in the inner pot to the boiling state and maintain the temperature of the food to be cooked at the boiling temperature or fluctuate around the boiling temperature. In addition, after the boiling stage, there can be a stewing stage. The main purpose of the stewing stage is to maintain the temperature of the food to be cooked in the inner pot at a high temperature range and provide a ripening time for the food to be cooked to ensure the cooking effect. Further, after the stewing stage, there can be a holding stage. The main purpose of the holding stage is to maintain the temperature of the food and improve the quality of the food provided to the user.

[0052] As shown in the example, Figure 1 The cooking appliance control method includes the following steps:

[0053] In step 102, in the cooking mode determination stage, the cooking mode of the cooking appliance is determined.

[0054] The cooking mode determination stage is generally before the formal start of cooking. In the cooking mode determination stage, the working parameters of various devices in the cooking appliance can be obtained to determine the cooking mode of the cooking appliance.

[0055] The type of the cooking mode is not unique. For example, the cooking mode includes a hot-state cooking mode and a normal-temperature cooking mode. The hot-state cooking mode represents that the interval time between the starting time of the current cooking process and the ending time of the previous cooking process is less than a preset interval time length. That is, the interval time between the starting time of the current cooking process and the ending time of the previous cooking process is short, and the cooking appliance has not cooled down to room temperature after the previous cooking process ends. At this time, the cooking appliance is usually in a hot state. Generally, in the hot-state cooking mode, the starting temperature of the cooking appliance is high. The normal-temperature cooking mode means that the overall temperature of the cooking appliance is close to room temperature at the start of cooking, and the cooking appliance is in a cold state. The temperature of the cooking appliance in the hot-state cooking mode is higher than the temperature of the cooking appliance in the normal-temperature cooking mode.

[0056] In step 104, in the soaking stage, if the cooking mode is the hot-state cooking mode, the first temperature of the cover of the cooking appliance at the ending time of the soaking stage is obtained.

[0057] The main purpose of the soaking stage is to promote water absorption of the food to be cooked and facilitate the ripening of the food to be cooked.

[0058] The hot cooking mode represents that the interval time between the starting moment of the current cooking process and the ending moment of the last cooking process is less than the preset interval length. In step 102, the cooking mode of the cooking appliance is determined. If it is determined that the cooking mode is the hot cooking mode, the steps corresponding to the hot cooking mode are performed in the subsequent soaking stage and the warming-up stage after the determination of the cooking mode is completed. For example, in the soaking stage, if the cooking mode is the hot cooking mode, the ending moment of the soaking stage is obtained, and the temperature of the cover of the cooking appliance is obtained as the first temperature.

[0059] The ending moment of the soaking stage is the moment of exiting the soaking stage. The condition of exiting the soaking stage is not unique. For example, the value of a parameter of the cooking appliance reaching a preset value, such as the temperature of the cover of the cooking appliance reaching a preset temperature value. The moment when the temperature of the cover reaches the preset temperature value can be taken as the ending moment of the soaking stage. Alternatively, the condition of exiting the soaking stage can also be that the duration of the soaking stage reaches a preset duration. The preset duration can be a default duration or a value set by the user. When the cooking appliance enters the soaking stage, the controller starts timing. When the duration of the soaking stage reaches the preset duration, it indicates that the ending moment of the soaking stage has been reached.

[0060] At the ending moment of the soaking stage, the first temperature of the cover of the cooking appliance is obtained. The temperature of the cover can be detected by the first temperature detection device, and the detected temperature value is sent to the controller, so that the controller obtains the first temperature of the cover of the cooking appliance. The first temperature detection device can be arranged on the cover to facilitate accurate detection of the temperature of the cover, and the first temperature detection device is also connected to the controller. Alternatively, the first temperature detection device can also be arranged on the pot body or other positions, as long as the temperature of the cover can be detected.

[0061] In step 106, in the warming-up stage, the control parameter of the warming-up stage is adjusted according to the first temperature.

[0062] The control parameter of the warming-up stage is a parameter that affects the heating effect of the warming-up stage, and the type of the control parameter of the warming-up stage is not limited. For example, it can be the heating duration, the heating power, etc.

[0063] The main purpose of the warming-up stage is to increase the temperature of the inner pot to heat the food to be cooked in the inner pot, so that the temperature of the food to be cooked gradually approaches or reaches the boiling temperature.

[0064] Generally, the first temperature of the cover at the end of the soaking stage in the hot-state cooking mode is higher than that in the normal-temperature cooking mode. Therefore, if the temperature of the cover reaching a preset temperature value is used as the condition for exiting the temperature rising stage, the temperature of the cover in the hot-state cooking mode is more likely to reach the preset temperature value than that in the normal-temperature cooking mode, which may cause the duration of the temperature rising stage to be too short in the hot-state cooking mode, and may cause insufficient heat in the subsequent boiling.

[0065] Therefore, after obtaining the first temperature of the cover of the cooking appliance at the end of the soaking stage, the control parameter of the temperature rising stage is adjusted according to the first temperature to adjust the heat of the temperature rising stage, generally to increase the heat of the temperature rising stage, so as to timely supplement the heat of the temperature rising stage in the case that the cooking appliance is in the hot-state cooking mode, and reduce the influence of insufficient heat on the cooking quality.

[0066] The cooking appliance control method, the cooking process of the cooking appliance includes a cooking mode determination stage, a soaking stage and a temperature rising stage executed in sequence. In the cooking mode determination stage, the cooking mode of the cooking appliance is determined. In the soaking stage, if the cooking mode is a hot-state cooking mode, the first temperature of the cover of the cooking appliance at the end of the soaking stage is obtained. The hot-state cooking mode represents that the interval time between the start time of the current cooking process and the end time of the previous cooking process is less than a preset interval time length. In the temperature rising stage, the control parameter of the temperature rising stage is adjusted according to the first temperature. Thus, the soaking stage and the temperature rising stage can effectively help to complete the food cooking. Before the soaking stage, there is also the cooking mode determination stage, in which whether the cooking mode is the hot-state cooking mode is determined. In the hot-state cooking mode, the control parameter of the temperature rising stage is adjusted according to the temperature of the cover at the end of the soaking stage. At this time, the temperature of the cover is the real temperature. The adjustment of the control parameter of the temperature rising stage according to the temperature of the cover can make the control parameter more suitable for the actual situation, which is beneficial to improve the cooking quality.

[0067] The way of determining the cooking mode of the cooking appliance is not unique. In the above embodiment, it is mentioned that in the cooking mode determination stage, the working parameters of each device in the cooking appliance can be obtained to determine the cooking mode of the cooking appliance. In this embodiment, taking the determination of the cooking mode of the cooking appliance by obtaining the initial temperature of the cover of the cooking appliance as an example. Figure 2 As shown in FIG. 2, step 102 includes step 202 and step 204.

[0068] In step 202, the initial temperature of the cover of the cooking appliance is obtained in the cooking mode determination stage.

[0069] Generally, the cooking mode determination stage is before the formal start of cooking. In this embodiment, it is before the soaking stage.

[0070] The way of obtaining the initial temperature of the cover of the cooking utensil is not limited. For example, in the cooking mode determination stage, the temperature of the cover can be detected by the first temperature detection device, and the detected temperature value can be sent to the controller to obtain the initial temperature of the cover of the cooking utensil. The first temperature detection device can be arranged on the cover to facilitate accurate detection of the temperature of the cover, and the first temperature detection device is also connected to the controller. Alternatively, the first temperature detection device can also be arranged on the pot body or other positions, as long as the temperature of the cover can be detected.

[0071] In step 204, if the initial temperature is greater than the preset initial temperature threshold, it is determined that the cooking mode of the cooking utensil is the hot-state cooking mode.

[0072] After obtaining the initial temperature of the cover, the initial temperature is compared with the preset initial temperature threshold. In the cooking mode determination stage, the cooking utensil has not formally started cooking, and the temperature of the cover reflects the temperature after being affected by the last cooking process. Therefore, if the initial temperature is greater than the preset initial temperature threshold, it indicates that the temperature of the cover is high at this time, and the interval time of the cooking utensil from the end time of the last cooking process is short, and the cooking utensil is in the hot-state cooking mode.

[0073] In this embodiment, in the cooking mode determination stage, the initial temperature of the cover of the cooking utensil is obtained, and if the initial temperature is greater than the preset initial temperature threshold, it is determined that the cooking mode of the cooking utensil is the hot-state cooking mode. According to the initial temperature of the cover of the cooking utensil, the detection of the cooking mode is simple and accurate.

[0074] Further, in an exemplary embodiment, as shown in Figure 3 Step 202 includes step 302: obtaining the initial temperature of the cover of the cooking utensil at the end of the cooking mode determination stage.

[0075] The cooking mode determination stage is generally the stage after receiving the cooking instruction and before formally starting cooking. After the controller receives the cooking instruction, the timing starts, and after the timing reaches the preset determination stage duration, the controller controls the cooking utensil to exit the cooking mode determination stage and enter the subsequent stage, such as the soaking stage. The specific value of the preset determination stage duration is not unique, for example, it can be any value within 30s-60s, including the end point values 30s and 60s.

[0076] In the cooking mode determination stage, the controller can also control the cooking utensil to perform self-checking, such as detecting whether the inner pot is placed in the pot body, whether it is dry burning, temperature condition, etc., so as to judge whether the cooking utensil can normally operate, whether there is an inner pot, judge the hot and cold state, etc., to provide basis for subsequent program operation.

[0077] At the end of the cooking mode determination stage, when other steps performed in the cooking mode determination stage such as self-checking have been completed, whether the subsequent steps are to be performed can be determined according to the self-checking result. For example, at the end of the cooking mode determination stage, the initial temperature of the cover of the cooking appliance is obtained after the self-checking passes. Not only can the cooking mode be determined according to the initial temperature, but also the subsequent other cooking processes can be normally performed after the cooking mode is determined.

[0078] In this embodiment, the initial temperature of the cover of the cooking appliance is obtained at the end of the cooking mode determination stage. This can not only effectively obtain the initial temperature of the cover and facilitate the determination of the cooking mode, but also facilitate the normal execution of the subsequent steps, thereby improving the working performance of the cooking appliance.

[0079] The way of adjusting the control parameter of the temperature rising stage is not unique. For example, in an embodiment, as shown in FIG. 4, step 106 includes step 406: adjusting the control parameter of the temperature rising stage according to the difference value between the first temperature and the first preset exit temperature in the temperature rising stage. Figure 4

[0080] The first preset exit temperature is the exit temperature of the soaking stage in an ideal state. The ideal state can be that the cooking appliance is in the normal temperature cooking mode.

[0081] At the end of the soaking stage, if the cooking mode is the normal temperature cooking mode, the first temperature of the cover should be equal to or close to the first preset exit temperature. However, in the case of the hot state cooking mode, the initial temperature of the cover is high, so the first temperature of the cover at the end of the soaking stage is usually greater than the first preset exit temperature. Further, the difference value between the first temperature and the first preset exit temperature can reflect the degree to which the temperature of the cover is affected by the hot state cooking mode. The greater the difference value between the first temperature and the first preset exit temperature, the greater the influence of the hot state cooking mode on the temperature of the cover. The smaller the difference value between the first temperature and the first preset exit temperature, the smaller the influence of the hot state cooking mode on the temperature of the cover. The difference value can be a difference value or a ratio, which is not limited herein.

[0082] Further, the size of the difference value between the first temperature and the first preset exit temperature will also affect the heating effect of the subsequent temperature rising stage. For example, the greater the difference value between the first temperature and the first preset exit temperature, the greater the influence of the hot state cooking mode on the temperature of the cover. Compared with the normal temperature cooking mode, the temperature of the cover is more likely to reach the exit temperature of the temperature rising stage, and the heat provided by the temperature rising stage is more likely to be insufficient. The smaller the difference value between the first temperature and the first preset exit temperature, the smaller the influence of the hot state cooking mode on the temperature of the cover. The temperature of the cover is less likely to reach the exit temperature of the temperature rising stage, and the heat provided by the temperature rising stage is less likely to be insufficient compared with the heat provided by the temperature rising stage in the normal temperature cooking mode. ​

[0083] In this embodiment, in the warming-up stage, the control parameter of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature. The control parameter of the warming-up stage can be adjusted according to the degree of influence of the heat state cooking mode on the cover temperature, so that the adjusted control parameter is more in line with the actual situation, and the intelligent degree of the cooking appliance is improved.

[0084] The type of control parameter is not unique, and correspondingly, the way of adjusting the control parameter of the warming-up stage is not unique. For example, in one embodiment, as shown in Figure 5 Step 406 includes step 506: in the warming-up stage, the exit temperature of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature.

[0085] The difference value between the first temperature and the first preset exit temperature can reflect the degree of influence of the heat state cooking mode on the cover temperature. The exit temperature of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature, so as to adjust the temperature rise of the warming-up stage to adjust the heat provided by the warming-up stage.

[0086] In the warming-up stage, the controller can obtain the temperature of the cover. When the temperature of the cover is greater than or equal to the exit temperature of the warming-up stage, it means that the warming-up requirement of the warming-up stage has been met, and then the cooking appliance can be controlled to exit the warming-up stage.

[0087] In this embodiment, in the warming-up stage, the exit temperature of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature. The heating effect of the warming-up stage can be intelligently adjusted according to the degree of influence of the heat state cooking mode on the cover temperature.

[0088] In another exemplary embodiment, as shown in Figure 6 Step 406 includes step 606: in the warming-up stage, the duration of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature.

[0089] The difference value between the first temperature and the first preset exit temperature can reflect the degree of influence of the heat state cooking mode on the cover temperature. The duration of the warming-up stage is adjusted according to the difference value between the first temperature and the first preset exit temperature, so as to adjust the heat provided by the warming-up stage.

[0090] In the warming-up stage, the controller can obtain the warming-up duration. When the warming-up duration is greater than or equal to the duration of the warming-up stage, it means that the warming-up requirement of the warming-up stage has been met, and then the cooking appliance can be controlled to exit the warming-up stage.

[0091] In the embodiment, in the warming-up stage, the duration of the warming-up stage is adjusted according to the difference between the first temperature and the first preset exit temperature, and the heating effect of the warming-up stage can be intelligently adjusted according to the influence of the heat state cooking mode on the cover temperature.

[0092] Further, in one exemplary embodiment, as shown in Figure 7 Step 506 includes step 706 and step 708.

[0093] In step 706, the initial exit temperature of the warming-up stage is obtained.

[0094] The initial exit temperature refers to the default exit temperature of the warming-up stage, which is generally the exit temperature in the normal temperature cooking mode. The initial exit temperature can be a default value or can be set by the user according to specific requirements. After entering the warming-up stage, the controller calls the initial exit temperature of the warming-up stage for subsequent processing.

[0095] In step 708, the initial exit temperature is corrected according to the adjustment value corresponding to the difference between the first temperature and the first preset exit temperature to determine the exit temperature of the warming-up stage.

[0096] The difference between the first temperature and the first preset exit temperature can reflect the influence of the heat state cooking mode on the cover temperature. According to the difference between the first temperature and the first preset exit temperature, the corresponding adjustment value can also be different, and then the initial exit temperature is corrected according to the determined adjustment value to determine the exit temperature of the warming-up stage.

[0097] For example, the greater the difference between the first temperature and the first preset exit temperature, the greater the influence of the heat state cooking mode on the cover temperature, and compared with the normal temperature cooking mode, the cover temperature is more likely to reach the exit temperature of the warming-up stage, and the heat provided by the warming-up stage is more likely to be insufficient. In this case, the greater the adjustment value corresponding to the difference between the first temperature and the first preset exit temperature, the greater the correction range of the initial exit temperature, which can greatly increase the exit temperature of the warming-up stage, greatly increase the heat provided by the warming-up stage, reduce the influence on the subsequent cooking process, and thus reduce the influence of the heat state cooking mode.

[0098] The smaller the difference between the first temperature and the first preset exit temperature, the smaller the influence of the heat state cooking mode on the cover temperature. In this case, the smaller the adjustment value corresponding to the difference between the first temperature and the first preset exit temperature, the smaller the correction range of the initial exit temperature, which can slightly increase the exit temperature of the warming-up stage, appropriately increase the heat provided by the warming-up stage, reduce the influence on the subsequent cooking process, and thus reduce the influence of the heat state cooking mode.

[0099] In this embodiment, the initial exit temperature is corrected according to the adjustment value corresponding to the difference value between the first temperature and the first preset exit temperature, and the exit temperature of the warming-up stage is determined. The initial exit temperature can be accurately corrected according to the actual temperature condition, and the accuracy of the obtained exit temperature of the warming-up stage is improved, thereby facilitating improvement of the cooking quality.

[0100] The condition for exiting the warming-up stage is not unique. In an example, as shown in FIG. 8, the control method of the cooking appliance further includes steps 802 and 804. Figure 8

[0101] In step 802, the temperature of the cover and the temperature of the inner pot of the cooking appliance are obtained.

[0102] In the warming-up stage, the controller obtains the temperature of the cover and the temperature of the inner pot. The temperature of the cover can be detected by the first temperature detection device and then sent to the controller. The temperature of the inner pot can be detected by the second temperature detection device and then sent to the controller. The first temperature detection device can be arranged on the cover and connected to the controller. The second temperature detection device can be arranged on the pot body, specifically on the side of the pot body in contact with the bottom surface of the inner pot, so as to facilitate detection of the temperature of the inner pot. The second temperature detection device is also connected to the controller.

[0103] In step 804, the warming-up stage is exited when the temperature of the cover is greater than or equal to the exit temperature of the warming-up stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature.

[0104] When the temperature of the cover is greater than or equal to the exit temperature of the warming-up stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature, it indicates that the warming-up requirement of the warming-up stage has been met, and the temperatures of the cover and the inner pot have reached the required temperatures. At this time, the cooking appliance is controlled to exit the warming-up stage. The value of the second preset exit temperature is not unique. For example, the second preset exit temperature can be any value within 70-100℃, which can be set according to actual conditions.

[0105] In this embodiment, the temperature of the cover and the temperature of the inner pot of the cooking appliance are obtained, and the warming-up stage is exited when the temperature of the cover is greater than or equal to the exit temperature of the warming-up stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature. This can make the temperatures of the cover and the inner pot meet the temperature requirement, and facilitate improvement of the working reliability of the cooking appliance.

[0106] In addition, in an example, the control method of the cooking appliance further includes the step of: after exiting the warming-up stage, controlling the cooking appliance to enter the boiling stage.

[0107] ​The main purpose of the warming-up stage is to increase the temperature of the inner pot, so as to heat the food to be cooked in the inner pot, and gradually increase the temperature of the food to be cooked to the boiling temperature. After the warming-up stage, there is a boiling stage, and the cooking appliance is controlled to enter the boiling stage after exiting the warming-up stage. The main purpose of the boiling stage is to heat the food to be cooked in the inner pot to a boiling state, so as to keep the temperature of the food to be cooked at the boiling temperature or fluctuate around the boiling temperature.

[0108] In this embodiment, the cooking appliance is controlled to enter the boiling stage after exiting the warming-up stage, which is beneficial to improve the success probability of food cooking.

[0128] In one example embodiment, a cooking device is provided, comprising a cooking appliance and a cooking appliance control device according to any of the above embodiments.

[0129] In order to better understand the above-mentioned embodiments, the following detailed explanation is made in combination with a specific embodiment. In one embodiment, the cooking device includes a cooking appliance and a cooking appliance control device, the cooking appliance is an electric rice cooker, and the cooking appliance control device includes a first temperature detection device, a second temperature detection device, and a controller. The first temperature detection device is used to detect the temperature of the cover of the cooking appliance and send it to the controller. The second temperature detection device is used to detect the temperature of the inner pot of the cooking appliance and send it to the controller.

[0130] The electric rice cooker generally includes a cooker body. The cooker body can be in a general round rectangular cuboid shape, a general cylindrical shape, or any other suitable shape. A generally cylindrical or any other suitable shape inner pot is arranged in the cooker body. A cover is arranged on the upper cover of the cooker body. A first temperature detection device is arranged on the cover, and a second temperature detection device is arranged at the bottom of the inner pot for detecting the temperature of the bottom of the inner pot. The first temperature detection device and the second temperature detection device are connected to the controller of the cooking appliance, and after sensing the top and bottom temperatures, the sensed temperature signals are fed back to the controller, so that the controller can more accurately control the cooking process according to the temperature signals.

[0131] The cooking process mainly includes a cooking mode determination stage, a soaking stage, a warming-up stage, a boiling stage, and a stewing stage. The method mainly adjusts the control parameters of the warming-up stage. As shown in the following table, the cooking appliance control method includes the following steps: Figure 10

[0132] ① Cooking mode determination stage: After the heating device of the cooking appliance is powered on and the heating state is not started, the top temperature is obtained, and it is judged whether the top temperature is greater than a preset temperature T0 (generally between 35℃-45℃). If the top temperature is greater than T0, the cooking appliance is controlled to enter a hot cooking mode, which means that the cooking appliance is in a hot state when it starts cooking, and the temperature of the temperature sensing device is high. This is mainly to improve the cooking effect of the cooking appliance in a hot state, such as undercooked rice. Otherwise, the cooking appliance is controlled to enter a normal cooking mode to start cooking. The time of this stage is generally t0, and the top temperature recorded at the end of this stage is compared with T0. Among them, t0 is the self-checking stage before the rice cooker starts cooking, and the main functions include checking the pot, dry burning, and detecting the temperature change of the temperature sensing bag. The rice cooker program generally needs this time, and the effect is mainly to judge whether the rice cooker can operate normally, whether there is an inner pot, and to judge the cold and hot state, etc., to provide a basis for subsequent program operation.

[0133] ② Soaking stage: The heating power and time of this stage are the same as those of the normal (normal temperature cooking mode). After this stage is ended, the top temperature Tt at the time of exiting this stage is recorded and compared with a preset temperature value T1. According to actual experience, it is known that 42℃≤T1≤60℃, and according to the temperature signal, the rice cooker is controlled to enter the next stage.​​ The numerical values ​​are used to adjust the heating control parameters for the next stage (i.e., the heating stage).

[0134] ③ Heating Phase: In hot cooking mode, the top temperature at the end of the soaking phase is higher than in normal conditions. The exit temperature of the heating phase is the preset temperature value T2. Therefore, in hot conditions, the top temperature of the heating phase more easily reaches T2, resulting in a relatively shorter heating time during this phase, which may lead to insufficient heat during subsequent boiling. Therefore, this method uses the difference between the top temperature at the end of the soaking phase and the preset temperature value T1. The value of the exit temperature T2 during the heating phase is adjusted to the value of ...

[0135] Table 1

[0136]

[0137] That is, if If the value is ≤2, then the adjusted exit temperature value T2' of the heating stage is equal to the original exit temperature value T2 of the heating stage; if value (2,5) Then the adjusted exit temperature value T2' of the heating stage is equal to the original exit temperature value T2 plus 2, and so on. The heating of subsequent stages after the heating stage is carried out as usual. In addition, under hot conditions, the exit condition of the heating stage is that the top temperature is ≥ T2' and the bottom temperature is ≥ T3 (70℃ < T3 < 100℃).

[0138] This solution addresses the problem of poor rice cooking results in current rice cookers that start cooking before the rice has cooled to room temperature and while the heating element is still hot. By identifying the thermal state of the cooking appliance and adjusting the heating control parameters during the heating phase, the solution ensures optimal rice cooking.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
