[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with 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 utensil control method provided in the embodiment of the present application is used to control the cooking utensil. Among them, the cooking utensil includes but is not limited to an electric rice cooker, a stew pot, an electric pressure cooker, etc. The structure of the cooking utensil is not unique. For example, the cooking utensil 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 to increase the temperature of the food to be cooked in the inner pot, so as to cook the food. The cover body is arranged on the pot body, and the cover body is used to form a cooking space with the pot body when closed, and the inner pot is in the cooking space. Expandably, the pot body can be in the shape of a generally rounded rectangular parallelepiped, a generally cylindrical shape or any other suitable shape. An inner pot in a generally cylindrical shape or any other suitable shape is arranged in the pot body.

[0050] The cooking utensil control method may be executed by a controller in the cooking utensil, or by a terminal or server that is communicatively connected to the cooking utensil. The terminal may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The following embodiments are mostly described by taking the cooking utensil control method executed by a controller as an example.

[0051] In an exemplary embodiment, a cooking appliance control method is provided, and the cooking process of the cooking appliance includes a cooking mode determination stage, a soaking stage, and a heating stage, which are performed in sequence. The main purpose of the cooking mode determination stage is to detect the cooking mode of the cooking appliance, and the main purpose of the soaking stage is to promote the water absorption of the food to be cooked, which is conducive to the maturation of the food to be cooked. The main purpose of the heating 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 the boiling temperature. It can be understood that after the heating stage, there is also a boiling stage, and the main purpose of the boiling stage is to heat the food to be cooked in the inner pot to a boiling state, so that the temperature of the food to be cooked is maintained at the boiling temperature, or fluctuates around the boiling temperature. In addition, after the boiling stage, there can also be a stewing stage, and the main purpose of the stewing stage is to maintain the temperature of the food to be cooked in the inner pot within a higher temperature range, provide a period of maturation time for the food to be cooked, so as to ensure the cooking effect. Further, after the stewing stage, there can also be a heat preservation stage, and the main purpose of the heat preservation stage is to maintain the temperature of the food and improve the quality of the food provided to the user.

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

[0053] Step 102, in the cooking mode determination phase, the cooking mode of the cooking appliance is determined.

[0054] The cooking mode determination stage is generally before the cooking formally starts. In the cooking mode determination stage, the working parameters of each component in the cooking appliance can be obtained to determine the cooking mode of the cooking appliance.

[0055] There are not only one type of cooking mode. Exemplarily, the cooking mode includes a hot cooking mode and a normal temperature cooking mode. The hot cooking mode indicates that the interval 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. That is, the interval between the start time of the current cooking process and the end time of the previous cooking process is short. After the end of the previous cooking process, the cooking utensils have not yet cooled to room temperature, and the cooking utensils are usually in a hot state. Generally, in the hot cooking mode, the starting temperature of the cooking utensils is higher. The normal temperature cooking mode means that at the beginning of cooking, the overall temperature of the cooking utensils is close to room temperature and the cooking utensils are in a cold state. The temperature of the cooking utensils in the hot cooking mode is greater than the temperature of the cooking utensils in the normal temperature cooking mode.

[0056] Step 104, during the soaking stage, if the cooking mode is the hot cooking mode, obtain a first temperature of the cover of the cooking utensil at the end of the soaking stage.

[0057] Among them, the main purpose of the soaking stage is to promote the water absorption of the food to be cooked, which is beneficial to the cooking of the food to be cooked.

[0058] The hot cooking mode indicates that the interval between the start time of the current cooking process and the end time of the previous cooking process is less than the preset interval time. In step 102, the cooking mode of the cooking utensil is judged. If the cooking mode is determined to be the hot cooking mode, then after the cooking mode determination phase is completed, the steps corresponding to the hot cooking mode must be performed in the subsequent soaking phase and the heating phase. Exemplarily, in the soaking phase, if the cooking mode is the hot cooking mode, the temperature of the cover of the cooking utensil at the end of the soaking phase needs to be obtained as the first temperature.

[0059] The end time of the soaking stage is the moment of exiting the soaking stage. The condition for exiting the soaking stage is not unique. For example, the value of a certain parameter of the cooking utensil reaches a preset value, such as the temperature of the cover of the cooking utensil reaches a preset temperature value. The moment when the temperature of the cover reaches the preset temperature value can be used as the end time of the soaking stage. Alternatively, the condition for 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 utensil enters the soaking stage, the controller starts timing, and when the duration of the soaking stage reaches the preset duration, it means that the soaking stage has ended.

[0060] At the end of the soaking stage, the first temperature of the cover of the cooking utensil is obtained. The temperature of the cover can be detected by a 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 utensil. The first temperature detection device can be set 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. Optionally, the first temperature detection device can also be set on the pot body or other positions, as long as the temperature of the cover can be detected.

[0061] Step 106: During the heating stage, adjust the control parameters of the heating stage according to the first temperature.

[0062] Among them, the control parameters of the heating stage are parameters that affect the heating effect of the heating stage. The type of the control parameters of the heating stage is not limited. For example, it can be heating time, heating power, etc.

[0063] The main purpose of the heating 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 speaking, when the cooking appliance is in the hot cooking mode, the first temperature of the cover at the end of the soaking stage will be higher than the temperature in the normal temperature cooking mode. Therefore, if the cover temperature reaching a certain preset temperature value is used as a condition for exiting the heating stage, the cover temperature in the hot cooking mode is easier to reach the preset temperature value than in the normal temperature cooking mode. This may cause the heating stage in the hot cooking mode to last too short, which may result in insufficient heat during subsequent boiling.

[0065] Therefore, after obtaining the first temperature of the cover of the cooking utensil at the end of the soaking stage, the control parameters of the heating stage are adjusted according to the first temperature to adjust the heat in the heating stage, generally to increase the heat in the heating stage. The heat in the heating stage can be replenished in time when the cooking utensil is in a hot cooking mode, thereby reducing the impact of insufficient heat on cooking quality.

[0066] In the above cooking utensil control method, the cooking process of the cooking utensil includes a cooking mode determination stage, a soaking stage and a heating stage which are executed in sequence. In the cooking mode determination stage, the cooking mode of the cooking utensil is determined; in the soaking stage, if the cooking mode is a hot cooking mode, the first temperature of the cover of the cooking utensil at the end of the soaking stage is obtained; the hot cooking mode indicates that the interval between the start time of the current cooking process and the end time of the previous cooking process is less than the preset interval time; in the heating stage, the control parameters of the heating stage are adjusted according to the first temperature. Thus, the soaking stage and the heating stage can effectively help complete the cooking of food. There is also a cooking mode determination stage before the soaking stage. In the cooking mode determination stage, it is determined whether the cooking mode is a hot cooking mode. In the hot cooking mode, the control parameters of the heating stage are adjusted according to the temperature of the cover at the end of the soaking stage. The temperature of the cover at this time is the real temperature. The control parameters of the heating stage are adjusted according to the temperature of the cover, so that the control parameters are more in line with the actual situation, which is conducive to improving the cooking quality.

[0067] There is not only one way to determine the cooking mode of a cooking appliance. In the above embodiment, it is mentioned that in the cooking mode determination stage, the cooking mode of the cooking appliance can be determined by obtaining the working parameters of each component in the cooking appliance. In this embodiment, the cooking mode of the cooking appliance is determined by obtaining the initial temperature of the cover of the cooking appliance. In an exemplary embodiment, Figure 2 As shown, step 102 includes step 202 and step 204 .

[0068] Step 202: in the cooking mode determination stage, obtaining the initial temperature of the cover of the cooking utensil.

[0069] The cooking mode determination stage is generally before the cooking officially starts, and in this embodiment, before the soaking stage.

[0070] The method 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 a first temperature detection device, and the detected temperature value can be sent to the controller, so that the controller obtains the initial temperature of the cover of the cooking utensil. The first temperature detection device can be set 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. Optionally, the first temperature detection device can also be set on the pot body or other positions, as long as the temperature of the cover can be detected.

[0071] Step 204: when the initial temperature is greater than a preset initial temperature threshold, determine that the cooking mode of the cooking appliance is a hot 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 appliance has not officially 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 means that the temperature of the cover is high at this time, the interval time between the cooking appliance and the end time of the last cooking process is short, and the cooking appliance is in the hot 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 when the initial temperature is greater than a preset initial temperature threshold, the cooking mode of the cooking utensil is determined to be a hot cooking mode. The cooking mode is detected according to the initial temperature of the cover of the cooking utensil, and the detection process is simple and the result is accurate.

[0074] Furthermore, in an exemplary embodiment, Figure 3 As shown, step 202 includes step 302: at the end of the cooking mode determination phase, obtaining the initial temperature of the cover of the cooking appliance.

[0075] The cooking mode determination phase is generally a phase after receiving the cooking instruction and before the formal start of cooking. The controller starts timing after receiving the cooking instruction, and after the timing reaches the preset duration of the determination phase, the cooking appliance is controlled to exit the cooking mode determination phase and enter a subsequent phase, such as the soaking phase. The specific value of the preset duration of the determination phase is not unique, for example, it can be any value within 30s-60s, including the endpoint values ​​30s and 60s.

[0076] During the cooking mode determination stage, the controller can also control the cooking appliance to perform self-inspection. For example, it can detect whether the inner pot is placed in the pot, whether it is dry-burned, the temperature condition, etc., so as to determine whether the cooking appliance can operate normally, whether there is an inner pot, determine the hot or cold state, etc., providing a basis for subsequent program operation.

[0077] At the end of the cooking mode determination phase, if other steps executed in the cooking mode determination phase have been completed, such as self-test, it can be determined whether to execute subsequent steps based on the self-test results. For example, after the self-test is passed, the initial temperature of the cover of the cooking utensil is obtained at the end of the cooking mode determination phase, which can not only determine the cooking mode based on the initial temperature, but also enable other subsequent cooking processes to proceed normally 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 phase. This can not only effectively obtain the initial temperature of the cover to facilitate the judgment of the cooking mode, but also facilitate the normal execution of subsequent steps, thereby improving the working performance of the cooking appliance.

[0079] The method of adjusting the control parameters in the heating stage is not unique. For example, in one embodiment, Figure 4 As shown, step 106 includes step 406: in the heating stage, according to the difference between the first temperature and the first preset exit temperature, adjusting the control parameters of the heating stage.

[0080] The first preset exit temperature is the exit temperature of the soaking stage under an ideal state. The ideal state may be that the cooking appliance is in a 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, when the cooking mode is the hot cooking mode, the initial temperature of the cover is higher, so at the end of the soaking stage, the first temperature of the cover will usually be greater than the first preset exit temperature. Further, the difference between the first temperature and the first preset exit temperature can reflect the extent to which the cover temperature is affected by the hot cooking mode. The greater the difference between the first temperature and the first preset exit temperature, the greater the impact of the hot cooking mode on the cover temperature; the smaller the difference between the first temperature and the first preset exit temperature, the smaller the impact of the hot cooking mode on the cover temperature. The difference value can be a difference value or a ratio, which is not limited here.

[0082] Furthermore, the difference between the first temperature and the first preset exit temperature will also affect the heating effect of the subsequent heating stage. Exemplarily, the greater the difference between the first temperature and the first preset exit temperature, the greater the influence of the cover body temperature on the hot cooking mode, and the cover body temperature is more likely to reach the exit temperature of the heating stage compared to the normal temperature cooking mode, and the heat provided in the heating stage is more likely to be insufficient. The smaller the difference between the first temperature and the first preset exit temperature, the less the influence of the cover body temperature on the hot cooking mode, the less likely the cover body temperature is to reach the exit temperature of the heating stage, and the difference between the heat provided in the heating stage and the heat provided in the heating stage of the normal temperature cooking mode is smaller.

[0083] In this embodiment, during the heating stage, the control parameters of the heating stage are adjusted according to the difference between the first temperature and the first preset exit temperature. The control parameters of the heating stage can be adjusted accordingly according to the degree to which the cover temperature is affected by the hot cooking mode, so that the adjusted control parameters are more in line with the actual situation, thereby improving the cooking intelligence of the cooking appliance.

[0084] The types of control parameters are not unique, and correspondingly, the methods of adjusting the control parameters in the heating stage are not unique. For example, in one embodiment, Figure 5 As shown, step 406 includes step 506: in the heating stage, adjusting the exit temperature of the heating stage according to the difference between the first temperature and the first preset exit temperature.

[0085] The difference between the first temperature and the first preset exit temperature can reflect the extent to which the lid temperature is affected by the hot cooking mode. The exit temperature of the heating stage is adjusted according to the difference between the first temperature and the first preset exit temperature, thereby adjusting the temperature rise in the heating stage to adjust the amount of heat provided in the heating stage.

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

[0087] In this embodiment, during the heating stage, the exit temperature of the heating stage is adjusted according to the difference between the first temperature and the first preset exit temperature, and the heating effect of the heating stage can be intelligently adjusted according to the extent to which the cover temperature is affected by the hot cooking mode.

[0088] In another exemplary embodiment, Figure 6 As shown, step 406 includes step 606: during the heating stage, adjusting the duration of the heating stage according to the difference between the first temperature and the first preset exit temperature.

[0089] The difference between the first temperature and the first preset exit temperature can reflect the extent to which the lid temperature is affected by the hot cooking mode. The duration of the heating phase is adjusted according to the difference between the first temperature and the first preset exit temperature to adjust the amount of heat provided in the heating phase.

[0090] During the heating stage, the controller can obtain the heating time. If the heating time is greater than or equal to the duration of the heating stage, it means that the heating requirements of the heating stage have been met, and the cooking appliance can be controlled to exit the heating stage.

[0091] In this embodiment, during the heating stage, the duration of the heating stage is adjusted according to the difference between the first temperature and the first preset exit temperature, and the heating effect of the heating stage can be intelligently adjusted according to the extent to which the cover temperature is affected by the hot cooking mode.

[0092] Furthermore, in an exemplary embodiment, Figure 7 As shown, step 506 includes step 706 and step 708 .

[0093] Step 706: During the heating stage, an initial exit temperature of the heating stage is obtained.

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

[0095] Step 708: Correct the initial exit temperature according to the adjustment value corresponding to the difference between the first temperature and the first preset exit temperature to determine the exit temperature in the heating stage.

[0096] The difference between the first temperature and the first preset exit temperature can reflect the extent to which the lid temperature is affected by the hot cooking mode. 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 heating stage.

[0097] Exemplarily, the greater the difference between the first temperature and the first preset exit temperature, the greater the influence of the cover body temperature on the hot cooking mode. Compared with the normal temperature cooking mode, the cover body temperature is more likely to reach the exit temperature of the heating stage, and the heat provided in the heating 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 amplitude of the correction of the initial exit temperature, and the exit temperature of the heating stage can be greatly increased, so that the heat provided in the heating stage is greatly increased, the heat in the heating stage is sufficient, and the influence on the subsequent cooking process is reduced, thereby reducing the influence of the hot cooking mode.

[0098] The smaller the difference between the first temperature and the first preset exit temperature, the less the lid temperature is affected by the hot cooking mode. 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 amplitude of the correction of the initial exit temperature, and the exit temperature in the heating stage can be slightly increased, so that the heat provided in the heating stage is appropriately increased, the heat in the heating stage is sufficient, and the influence on the subsequent cooking process is reduced, thereby reducing the influence of the hot cooking mode.

[0099] In this embodiment, 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 heating stage. The initial exit temperature can be accurately corrected according to the actual temperature conditions, thereby improving the accuracy of the exit temperature of the heating stage, which is beneficial to improving the cooking quality.

[0100] The conditions for exiting the heating stage are not unique. For example, in one embodiment, Figure 8 As shown, the cooking appliance control method further includes step 802 and step 804 .

[0101] Step 802, obtaining the temperature of the cover and the temperature of the inner pot of the cooking utensil.

[0102] During the heating stage, the controller will obtain the temperature of the lid and the temperature of the inner pot. The temperature of the lid can be detected by the first temperature detection device and sent to the controller. The temperature of the inner pot can be detected by the second temperature detection device and sent to the controller. The first temperature detection device can be set on the lid and connected to the controller. The second temperature detection device can be set 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 detect the temperature of the inner pot. The second temperature detection device is also connected to the controller.

[0103] Step 804, when the temperature of the cover is greater than or equal to the exit temperature of the heating stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature, exit the heating stage.

[0104] When the temperature of the cover is greater than or equal to the exit temperature of the heating stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature, it means that the heating requirement of the heating stage has been met, and the temperature of the cover and the temperature of the inner pot have reached the required temperature. At this time, the cooking appliance is controlled to exit the heating 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°C, which can be set according to actual conditions.

[0105] In this embodiment, the temperature of the lid and the temperature of the inner pot of the cooking utensil are obtained, and when the temperature of the lid is greater than or equal to the exit temperature of the heating stage, and the temperature of the inner pot is greater than or equal to the second preset exit temperature, the heating stage is exited. This allows the temperature of the lid and the temperature of the inner pot to meet the temperature requirements, which is beneficial to improving the working reliability of the cooking utensil.

[0106] Furthermore, in an exemplary embodiment, the cooking appliance control method further comprises the step of: after exiting the heating stage, controlling the cooking appliance to enter a boiling stage.

[0107] The main purpose of the heating 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 the boiling temperature. After the heating stage, there is a boiling stage. After exiting the heating stage, the cooking appliance is controlled to enter the boiling 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 that the temperature of the food to be cooked is maintained at the boiling temperature, or fluctuates around the boiling temperature.

[0108] In this embodiment, after exiting the temperature rising stage, the cooking appliance is controlled to enter the boiling stage, which is beneficial to improving the success rate of food cooking.

[0124] In an exemplary embodiment, a cooking appliance control device is provided, including a first temperature detection device and a controller, wherein the first temperature detection device is connected to the controller; the first temperature detection device is used to detect the temperature of a cover of the cooking appliance and send it to the controller, and the controller is used to control the cooking appliance according to the method of any of the above embodiments.

After the temperature of the inner pot is detected by the second temperature detection device and sent to the controller, the controller can control whether to exit the heating stage according to the temperature of the inner pot, which is conducive to improving the working reliability of the cooking utensil.

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

[0129] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, the cooking device includes a cooking utensil and a cooking utensil control device, the cooking utensil is an electric rice cooker, and the cooking utensil control device includes a first temperature detection device, a second temperature detection device and a controller. Among them, the first temperature detection device is used to detect the temperature of the cover of the cooking utensil and send it to the controller. The second temperature detection device is used to detect the temperature of the inner pot of the cooking utensil and send it to the controller.

[0130] The electric rice cooker generally includes a cooker body. The cooker body can be in the shape of a generally rounded rectangular parallelepiped, a generally cylindrical shape or any other suitable shape. An inner pot in a generally cylindrical shape or any other suitable shape is arranged in the cooker body. A cover body is arranged on the upper cover of the cooker body. A first temperature detection device is arranged on the cover body, and a second temperature detection device is arranged at the bottom of the inner pot to detect 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 utensil, and after sensing the top and bottom temperatures, the sensed temperature signals are fed back to the controller, so that the controller can achieve more accurate control of the cooking process according to the temperature signals.

[0131] The cooking process mainly includes the cooking mode determination stage, the soaking stage, the heating stage, the boiling stage and the rice stewing stage. This method mainly adjusts the control parameters of the heating stage. Fig.10 As shown, the cooking appliance control method includes the following steps:

[0132] ① Cooking mode determination stage: After the heating device of the cooking appliance is powered on and the heating state is not turned on, the top temperature is obtained to determine whether the top temperature is greater than the preset temperature T0 (generally between 35℃-45℃). If the top temperature is greater than T0, the cooking appliance is controlled to enter the hot cooking mode. This mode refers to the situation where the cooking appliance is in a hot state when it starts cooking, and the temperature of the temperature sensing device is high. It is mainly to improve the problem of poor cooking effects such as half-cooked rice when the cooking appliance is in a hot state; otherwise, the cooking appliance is controlled to enter the normal cooking mode to start cooking. This stage usually takes , the top temperature recorded at the end of this stage is compared with T0. Among them, the time t0 is the self-check stage before the rice cooker starts cooking. The main functions include checking the pot, dry burning and detecting the temperature change of the temperature sensor. The rice cooker program generally requires this time. The effect is mainly to judge whether the rice cooker can operate normally, whether there is an inner pot, and judge the hot and cold state, etc., to provide a basis for the subsequent program operation.

[0133] ② Soaking stage: The heating power and time in this stage are the same as those in normal (normal temperature cooking mode). After this stage, the top temperature Tt when exiting this stage is recorded and compared with the preset temperature value T1. According to actual experience, it is known that: 42℃≤T1≤60℃. The heating control parameters of the next stage (i.e. the heating stage) are adjusted according to the numerical value.

[0134] ③ Heating stage: In hot cooking mode, the top temperature at the exit of the soaking stage is higher than normal, and the temperature at the exit of the heating stage is the preset temperature value T2. Therefore, in hot conditions, the top temperature of the heating stage is easier to reach T2. Therefore, the relatively shorter heating time in this stage may lead to insufficient heat during subsequent boiling. Therefore, this method uses the difference between the top temperature at the end of the soaking stage and the preset temperature value T1. The exit temperature value T2 of the heating stage is adjusted according to the size of the temperature, and the adjusted temperature is recorded as T2' to ensure that the heat in this stage is sufficient and does not affect the subsequent cooking process. The specific adjustment method can be seen in Table 1:

[0135] Table 1

[0136]

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

[0138] This solution can improve the problem that the rice cooker currently on the market starts cooking when the rice cooker temperature device is still at a high temperature just after cooking, resulting in poor cooking effect. By identifying the hot state of the cooking utensil and adjusting the heating control parameters in the heating stage, the cooking effect of rice can be guaranteed.

To make the description concise, 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 pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
