Technical Field

[0001] The present invention relates to the field of control technologies, and more particularly, to a cooking device, a control method, a control device, and a readable storage medium thereof. Background Art

[0002] The cooking of porridge-like foods often uses the following cooking means:

[0003] Add the water and rice mixture to the stirring cavity, control the device to directly boil it at high power quickly until it boils, and then cook it at low power.

[0004] However, the porridge cooked by the above cooking method has the following drawbacks, such as: the cooked porridge is easy to stick to the bottom, not easy to pour out and clean, and when the sticking to the bottom is serious, it will directly burn the bottom. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0006] To this end, in the first aspect of the present invention, a control method for a cooking device is provided.

[0007] In the second aspect of the present invention, a control device for a cooking device is provided.

[0008] In the third aspect of the present invention, another control device for a cooking device is provided.

[0009] In the fourth aspect of the present invention, a readable storage medium is provided.

[0010] In the fifth aspect of the present invention, a cooking device is provided.

[0011] In view of this, according to the first aspect of the present invention, a control method for a cooking device is provided. The cooking device includes a stirring cavity and a heating device. The stirring cavity is used to hold the water and rice mixture, and the heating device is used to heat the water and rice mixture. The control method includes: controlling the heating device to operate at a first power until the duration that the temperature of the water and rice mixture is within a first temperature range is greater than or equal to a first duration; controlling the heating device to operate at a second power until the water and rice mixture boils; controlling the heating device to operate until the cooking of the water and rice mixture ends; wherein, when the water and rice mixture boils, the temperature of the water and rice mixture is a first temperature, the upper limit value of the first temperature range is less than the first temperature, the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, and the first power is less than the second power.

[0012] The technical solution of this application proposes a control method for a cooking device. By running the above control method, the cooking of the water and rice mixture can be achieved, and then porridge-like food can be cooked. During this process, the problem of the porridge-like food sticking to the bottom after cooking can be improved. While improving the problem of the porridge-like food sticking to the bottom after cooking, it is convenient for users to pour out the porridge and clean the cooking device. At the same time, the probability of the porridge sticking to the bottom is also reduced, and the success rate of porridge cooking is improved.

[0013] The technical solution of this application is implemented based on the following principle. Specifically, in the related technical solution, during the process of quickly boiling with high power, the water and rice mixture is quickly gelatinized at high temperature. Due to the high power used, the temperature of the bottom plate of the stirring cavity is relatively high, and the gelatinized water and rice mixture is extremely easy to stick to the inner wall of the stirring cavity. With subsequent heating, the sticking situation becomes more serious, and even bottom burning occurs.

[0014] During this process, by controlling the heating device to operate at a first power lower than the second power, so that before the water and rice mixture is heated to boiling, the water and rice mixture is kept in an environment of the first temperature range, enabling the water and rice mixture to basically complete gelatinization in this stage. Since the first power is less than the second power, the temperature of the inner wall of the stirring cavity can be reduced, making it not easy for the water and rice mixture to stick to the bottom during the gelatinization stage, thereby improving the problem of sticking to the bottom existing in the cooking of porridge-like food.

[0015] In the above technical solution, by limiting the lower limit value of the first temperature range to be higher than the gelatinization temperature of the water and rice mixture, it is avoided that due to the too low temperature of the water and rice mixture, gelatinization cannot occur, or after maintaining the first temperature range for the first duration, the water and rice mixture is still not completely gelatinized, or only a small part is gelatinized, which affects the cooking of porridge.

[0016] In some technical solutions, optionally, the gelatinization temperature of the water and rice mixture can be obtained through experiments and input into the cooking device, or input into the server communicating with the cooking device, so that the cooking device can obtain it through the server.

[0017] In some technical solutions, optionally, the control method of the cooking device further includes: obtaining the type of rice in the water and rice mixture; and finding the gelatinization temperature of the water and rice mixture according to the type of rice in the water and rice mixture.

[0018] It can be understood that the gelatinization temperature of the water and rice mixture is related to the type of rice in the water and rice mixture.

[0019] In the above technical solution, by limiting the upper limit value of the first temperature range to be less than the first temperature, it is avoided that the water and rice mixture is directly cooked in the environment of the first temperature range, which affects the preparation of porridge.

[0020] In some technical solutions, optionally, the color of the water and rice mixture can be observed through experiments, and when the color of the water and rice mixture is milky white, it is considered that the current gelatinization degree of the water and rice mixture is not likely to adhere to the inner wall of the stirring chamber. By recording the duration of the environment in which the water and rice mixture maintains the first temperature range, the calibration of the first duration is achieved.

[0021] In some technical solutions, optionally, during the process of the heating device operating at the first power, the working state of the heating device is controlled according to the comparison result between the temperature of the water and rice mixture and the first temperature range.

[0022] Specifically, when the temperature of the water and rice mixture is lower than the lower limit value of the first temperature range, the heating device is controlled to start heating; conversely, when the temperature of the water and rice mixture reaches the first temperature range, the heating device is controlled to stop heating.

[0023] Among them, when the temperature of the water and rice mixture reaches the first temperature range, it can be understood that the temperature of the water and rice mixture is between the lower limit value and the upper limit value of the first temperature range.

[0024] In addition, the control method of the cooking device proposed in this application also has the following additional technical features.

[0025] In some technical solutions, optionally, before the duration of the heating device operating at the first power until the temperature of the water and rice mixture is within the first temperature range is greater than or equal to the first duration, it further includes: controlling the heating device to operate at the third power until the temperature of the water and rice mixture rises to the first temperature range; where the third power is greater than the first power.

[0026] In the technical solution, by controlling the heating device to operate at the third power, so that the water and rice mixture can quickly increase in temperature and then reach the first temperature range. In this process, compared with the solution of always heating at the first power, the technical solution of this application can shorten the cooking duration of porridge, thereby reducing the waiting time of users, and thus improving the user experience.

[0027] In the above technical solution, the third power can be the same as or different from the second power. When the third power is different from the second power, the third power can be less than the second power. In this process, it can make the water and rice mixture have a relatively slow heating rate during the heating process, so as to improve the accuracy of temperature measurement. By limiting that the third power is greater than the first power, it is to avoid too small a heating rate, resulting in too long a total cooking duration and affecting the user experience.

[0028] In some technical solutions, optionally, during the process of controlling the heating device to operate at the third power, the control method further includes: when the temperature of the water and rice mixture rises by the second temperature value each time, controlling the stirring motor of the cooking device to rotate at the first speed for the second duration; wherein, when the stirring motor rotates, the stirring blade of the cooking device rotates in the stirring cavity to stir the water and rice mixture.

[0029] In this technical solution, by controlling the stirring motor to rotate at the first speed for the second duration, so as to stir the water and rice mixture by using the rotation of the stirring motor, making the temperatures of all parts in the water and rice mixture tend to be the same. During this process, during the process of the heating device operating at the third power, the accuracy of measuring the temperature of the water and rice mixture can be improved, thereby enhancing the precision of cooking control.

[0030] Specifically, by limiting the second temperature value, so that during the process of the heating device heating the water and rice mixture, the stirring motor does not rotate continuously, but rotates for a while and then stops for a while. During this process, while ensuring that the temperatures at all positions in the water and rice mixture tend to be the same, the running duration of the stirring motor can also be reduced, thereby enhancing the service life of the stirring motor.

[0031] In addition, since the stirring motor rotates for a while and then stops for a while, rather than rotating continuously, the power consumption of the cooking device can be reduced. At the same time, it is also convenient to reduce the noise generated when the cooking device works, improving the use experience.

[0032] In some technical solutions, optionally, the first speed and the second duration can be selected according to actual usage needs, and will not be elaborated here.

[0033] In some technical solutions, optionally, the second temperature value can be selected according to actual usage needs, such as 10 degrees Celsius, 5 degrees Celsius, or it can also be 3 degrees Celsius, or other values. Its specific value will not be elaborated here.

[0034] In some technical solutions, optionally, the second duration is the continuous duration for which the stirring motor rotates at the first speed.

[0035] In some technical solutions, optionally, the value of the first speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the second duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0036] In this embodiment, by limiting that the value of the first speed is greater than or equal to 1000 RPM, so that the rice in the water and rice mixture, that is, the food ingredients, can be separated from the bottom of the stirring cavity with the rotation of the stirring motor, avoiding the situation of sticking to the bottom due to too long contact time with the bottom of the stirring cavity.

[0037] Meanwhile, by limiting the value of the first rotation speed to not higher than 4000 RPM, it is possible to avoid completely crushing the rice in the water-rice mixture, that is, the ingredients, into powder form when the rotation speed of the stirring motor is too high. When the value of the first rotation speed is not higher than 4000 RPM, the rice in the water-rice mixture can be beaten into smaller granular forms, such as granular forms the size of millet or 1 / 4 the size of rice grains, to ensure the taste of the cooked porridge-like food.

[0038] In addition, when the value of the first rotation speed is greater than or equal to 1000 RPM, it is possible to avoid the situation where the temperature of the water-rice mixture cannot tend to be the same due to too low a rotation speed. On the contrary, by limiting the value of the first rotation speed to not higher than 4000 RPM, it is possible to avoid an excessive rotation speed, which increases the power consumption of the cooking device and generates a large amount of noise at the same time.

[0039] In the above technical solution, by limiting the second duration, the automatic control of the stirring motor can be realized, so that the stirring motor can be automatically started and stopped during the process of heating the water-rice mixture by the heating device.

[0040] In some technical solutions, optionally, before controlling the heating device to operate at the third power until the temperature of the water-rice mixture rises to the first temperature range, it further includes: controlling the stirring motor of the cooking device to rotate at the second rotation speed for the third duration; wherein, the first rotation speed is greater than or equal to the second rotation speed.

[0041] In this technical solution, by controlling the stirring motor to rotate at the second rotation speed for the third duration, during the rotation of the stirring motor, the stirring member can be driven to rotate to stir up the rice in the water-rice mixture, so as to separate it from the bottom wall of the stirring cavity and avoid the situation of sticking to the bottom due to too long contact time with the bottom of the stirring cavity. This provides a basis for subsequent heating at the third power. During this process, the sticking of the rice in the water-rice mixture to the bottom wall of the stirring cavity during the heating process by the heating device at the third power can be improved.

[0042] In some technical solutions, by limiting the second rotation speed to be less than the first rotation speed, during the process of the stirring motor rotating at the first rotation speed, it can rotate at a high speed to provide a large force to stir the water-rice mixture. At the same time, during the rotation at the second rotation speed, it can stir in a relatively gentle manner to reduce the noise generated by the stirring.

[0043] In some technical solutions, the value range of the second rotation speed is the same as that of the first rotation speed, that is, the value of the second rotation speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM.

[0044] In the above technical solution, the third duration can be set according to actual usage needs and will not be elaborated here.

[0045] In some technical solutions, optionally, the third duration is the duration for which the stirring motor rotates at the second rotational speed.

[0046] In some technical solutions, optionally, after controlling the heating device to operate until the boiling of the water and rice mixture ends, it further includes: controlling the stirring motor of the cooking device to rotate at the third rotational speed for the fourth duration.

[0047] In this technical solution, by controlling the stirring motor to rotate at the third rotational speed, the stirring member is driven to stir during the rotation of the stirring motor, so that the cooked porridge food is separated from the bottom wall of the stirring cavity.

[0048] During this process, the slight adhesion between the cooked porridge food and the bottom wall of the stirring cavity can be improved. Thus, while facilitating the user to pour the porridge food out of the stirring cavity, it is also convenient for cleaning after pouring the porridge food out of the stirring cavity, thereby improving the difficulty of pouring the porridge food and the cleaning difficulty of the stirring cavity.

[0049] In some technical solutions, the fourth duration can be the duration for which the stirring motor continuously rotates at the third rotational speed, or the cumulative duration when the stirring motor rotates intermittently at the third rotational speed.

[0050] In some technical solutions, optionally, the value of the third rotational speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the fourth duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0051] In some technical solutions, optionally, the temperature value of the first temperature range is greater than or equal to 50 degrees Celsius and less than or equal to 80 degrees Celsius; and / or the value of the first duration is greater than or equal to 3 minutes and less than or equal to 15 minutes.

[0052] In this technical solution, the first temperature range can be determined according to the type of rice in the water and rice mixture. Specifically, a corresponding relationship between different rice types and different first temperature ranges is pre - constructed. Then, when the type of rice in the water and rice mixture placed in the stirring cavity is determined, the first temperature range is obtained based on the above - mentioned corresponding relationship.

[0053] In some technical solutions, optionally, controlling the heating device to operate until the boiling of the water and rice mixture ends specifically includes: controlling the heating device to operate at the fourth power until the heating device operates at the fourth power for the fifth duration; where the fourth power is less than or equal to the first power.

[0054] In this technical solution, by controlling the heating device to operate at a fourth power for a fifth duration, so that the rice-water mixture can be cooked thoroughly. During this process, the occurrence of undercooked porridge can be reduced, thereby increasing the cooking success rate of porridge.

[0055] In some technical solutions, optionally, the fifth duration can be the continuous duration when the heating device operates continuously at the fourth power, or the cumulative duration when the heating device operates intermittently at the fourth power.

[0056] In the above technical solution, by limiting the fourth power to be not higher than the first power, so as to avoid the situation that the cooked porridge sticks to the bottom due to excessive power.

[0057] In some technical solutions, optionally, the fourth power is greater than or equal to 100 watts and less than or equal to 500 watts; and / or the value of the fifth duration is greater than or equal to 10 minutes and less than or equal to 60 minutes.

[0058] According to the second aspect of the present invention, the present invention provides a control device for a cooking device. The cooking device includes a stirring chamber and a heating device. The stirring chamber is used to hold the water-rice mixture, and the heating device is used to heat the water-rice mixture. The control device includes: a first control unit for controlling the heating device to operate at a first power until the continuous duration of the temperature of the water-rice mixture being in a first temperature range is greater than or equal to a first duration; a second control unit for controlling the heating device to operate at a second power until the water-rice mixture boils; a third control unit for controlling the heating device to operate until the cooking of the water-rice mixture ends; wherein, when the water-rice mixture boils, the temperature of the water-rice mixture is a first temperature, the upper limit value of the first temperature range is less than the first temperature, the lower limit value of the first temperature range is higher than the gelatinization temperature of the water-rice mixture, and the first power is less than the second power.

[0059] The technical solution of the present application proposes a control device for a cooking device, which can realize the cooking of the water-rice mixture, and then cook porridge-like food. During this process, the problem of the cooked porridge sticking to the bottom can be improved. While improving the problem of the cooked porridge sticking to the bottom, it is convenient for the user to pour out the porridge and clean the cooking device. At the same time, the probability of the porridge sticking to the bottom is also reduced, and the success rate of porridge cooking is increased.

[0060] The technical solution of the present application is realized based on the following principle. Specifically, in the related technical solution, during the process of quickly boiling to boiling with high power, the water-rice mixture is quickly gelatinized at high temperature. Due to the high power used, the bottom plate temperature of the stirring chamber is relatively high, and the gelatinized water-rice mixture is extremely easy to adhere to the inner wall of the stirring chamber. With subsequent heating, the adhesion situation becomes more serious, and even bottom burning occurs.

[0061] During this process, by controlling the heating device to operate at a first power lower than the second power, so that before heating the water and rice mixture to boiling, the water and rice mixture is maintained in an environment of a first temperature range, enabling the water and rice mixture to basically complete gelatinization within this stage. Since the first power is less than the second power, the temperature of the inner wall of the stirring chamber can be reduced, making it less likely to stick to the bottom during the gelatinization stage of the water and rice mixture, thereby improving the problem of sticking to the bottom existing in the cooking of porridge-like foods.

[0062] In the above technical solution, by defining that the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, it is avoided that due to the too low temperature of the water and rice mixture, gelatinization cannot occur, or after maintaining the first temperature range for the first duration, the water and rice mixture is still not completely gelatinized, or only a small part is gelatinized, which affects the cooking of porridge.

[0063] In some technical solutions, optionally, the gelatinization temperature of the water and rice mixture can be obtained through experimental determination and input into the cooking device, or input into the server communicating with the cooking device, so that the cooking device can obtain it through the server.

[0064] In some technical solutions, optionally, the control method of the cooking device further includes: obtaining the type of rice in the water and rice mixture; finding the gelatinization temperature of the water and rice mixture according to the type of rice in the water and rice mixture.

[0065] It can be understood that the gelatinization temperature of the water and rice mixture is related to the type of rice in the water and rice mixture.

[0066] In the above technical solution, by defining that the upper limit value of the first temperature range is less than the first temperature, it is avoided that the water and rice mixture is directly cooked in the environment where the water and rice mixture maintains the first temperature range, which affects the preparation of porridge.

[0067] In some technical solutions, optionally, the color of the water and rice mixture can be observed through experiments, and when the color of the water and rice mixture is milky white, it is considered that the current gelatinization degree of the water and rice mixture is not likely to adhere to the inner wall of the stirring chamber. By recording the continuous duration of the environment where the water and rice mixture maintains the first temperature range, the calibration of the first duration is achieved.

[0068] In some technical solutions, optionally, during the process of the heating device operating at the first power, the working state of the heating device is controlled according to the comparison result between the temperature of the water and rice mixture and the first temperature range.

[0069] Specifically, in the case where the temperature of the water and rice mixture is lower than the lower limit value of the first temperature range, the heating device is controlled to start heating; conversely, when the temperature of the water and rice mixture reaches the first temperature range, the heating device is controlled to stop heating.

[0070] Among them, the temperature of the water and rice mixture reaching the first temperature range can be understood as the temperature of the water and rice mixture being between the lower limit value and the upper limit value of the first temperature range.

[0071] In addition, the control device of the cooking device proposed in this application also has the following additional technical features.

[0072] In some technical solutions, optionally, before the duration of controlling the heating device to operate at the first power until the temperature of the water and rice mixture is within the first temperature range is greater than or equal to the first duration, the first control unit is further configured to: control the heating device to operate at the third power until the temperature of the water and rice mixture rises to the first temperature range; wherein, the third power is greater than the first power.

[0073] In the technical solution, by controlling the heating device to operate at the third power, so that the water and rice mixture can be quickly heated up to reach the first temperature range. In this process, compared with the solution of always heating at the first power, the technical solution of this application can shorten the cooking duration of the porridge, thereby reducing the waiting time of the user, and thus improving the user experience.

[0074] In the above technical solution, the third power can be the same as or different from the second power. When the third power is different from the second power, the third power can be less than the second power. In this process, it can make the water and rice mixture have a relatively slow heating rate during the heating process, so as to improve the accuracy of temperature measurement. By limiting that the third power is greater than the first power, it is to avoid too small a heating rate, resulting in too long a total cooking duration and affecting the user experience.

[0075] In some technical solutions, optionally, during the process of controlling the heating device to operate at the third power, the first control unit is further configured to: when the temperature of the water and rice mixture rises by the second temperature value each time, control the stirring motor of the cooking device to rotate at the first speed for the second duration; wherein, when the stirring motor rotates, the stirring blade of the cooking device rotates in the stirring cavity to stir the water and rice mixture.

[0076] In this technical solution, by controlling the stirring motor to rotate at the first speed for the second duration, so as to use the rotation of the stirring motor to stir the water and rice mixture, making the temperatures of each part of the water and rice mixture tend to be the same. In this process, during the process of the heating device operating at the third power, the accuracy of measuring the temperature of the water and rice mixture can be improved, and thus the accuracy of cooking control is improved.

[0077] Specifically, by limiting the second temperature value, during the process of heating the water and rice mixture by the heating device, the stirring motor does not rotate continuously, but rotates for a while and then stops for a while. During this process, while ensuring that the temperatures at various positions in the water and rice mixture tend to be the same, the operating duration of the stirring motor can be reduced, thereby improving the service life of the stirring motor.

[0078] In addition, since the stirring motor rotates for a while and then stops for a while instead of rotating continuously, the power consumption of the cooking device can be reduced. At the same time, it is also convenient to reduce the noise generated during the operation of the cooking device and improve the user experience.

[0079] In some technical solutions, optionally, the first rotation speed and the second duration can be selected according to actual usage needs and will not be elaborated here.

[0083] In this embodiment, by limiting the value of the first rotation speed to be greater than or equal to 1000 RPM, the rice in the water and rice mixture, that is, the food ingredient, can be separated from the bottom of the stirring cavity as the stirring motor rotates, avoiding prolonged contact with the bottom of the stirring cavity and preventing sticking to the bottom.

[0084] At the same time, by limiting the value of the first rotation speed to not exceed 4000 RPM, it is possible to prevent the rice in the water and rice mixture, that is, the food ingredient, from being completely crushed into powder when the rotation speed of the stirring motor is too high. When the value of the first rotation speed does not exceed 4000 RPM, the rice in the water and rice mixture can be beaten into smaller granular shapes, such as granular shapes the size of millet or 1 / 4 the size of a rice grain, to ensure the texture of the porridge-like food obtained through cooking.

[0085] In addition, when the value of the first rotation speed is greater than or equal to 1000 RPM, it is possible to prevent the temperature of the water and rice mixture from not tending to be the same due to too low a rotation speed. On the contrary, by limiting the value of the first rotation speed to not exceed 4000 RPM, it is possible to prevent an increase in the power consumption of the cooking device and the generation of excessive noise due to too high a rotation speed.

[0117] In order to more clearly understand the above aspects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0118] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0119] In one embodiment of the present application, as Figure 1 and Figure 2 shown, a control method for a cooking device is provided. The cooking device includes a stirring chamber 202 and a heating device 204. The stirring chamber 202 is used to accommodate a water and rice mixture, and the heating device 204 is used to heat the water and rice mixture. The control method includes:

[0120] Step 102, controlling the heating device to operate at a first power until the duration for which the temperature of the water and rice mixture is within a first temperature range is greater than or equal to a first duration;

[0121] Step 104, controlling the heating device to operate at a second power until the water and rice mixture boils;

[0122] Step 106, controlling the heating device to operate until the boiling of the water and rice mixture ends.

[0123] Wherein, when the water and rice mixture boils, the temperature of the water and rice mixture is a first temperature. The upper limit value of the first temperature range is less than the first temperature, the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, and the first power is less than the second power.

[0124] The embodiment of the present application provides a control method for a cooking device. By operating the above control method, the cooking of the water and rice mixture can be realized, and then porridge-like food can be cooked. During this process, the problem of sticking to the bottom of the porridge-like food obtained after cooking can be improved. While improving the problem of sticking to the bottom of the porridge-like food obtained after cooking, it is convenient for the user to pour out the porridge and clean the cooking device. At the same time, the probability of the porridge sticking to the bottom is also reduced, and the success rate of porridge cooking is improved.

[0125] The embodiment of the present application is based on the following principle. Specifically, in the related embodiments, during the process of quickly boiling to boiling with high power, the water and rice mixture is quickly gelatinized at high temperature. Due to the high power used, the bottom plate temperature of the stirring chamber is relatively high, and the gelatinized water and rice mixture is extremely easy to adhere to the inner wall of the stirring chamber. With subsequent heating, the adhesion situation becomes more serious, and even bottom burning occurs.

[0126] During this process, by controlling the heating device to operate at a first power lower than the second power, so that before heating the water and rice mixture to boiling, the water and rice mixture is maintained in an environment of a first temperature range, enabling the water and rice mixture to basically complete gelatinization within this stage. Since the first power is less than the second power, the temperature of the inner wall of the stirring chamber can be reduced, making it less likely to stick to the bottom during the gelatinization stage of the water and rice mixture, thereby improving the problem of sticking to the bottom in the cooking of porridge-like foods.

[0127] In the above embodiment, by defining that the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, it is avoided that due to the too low temperature of the water and rice mixture, gelatinization cannot occur, or after maintaining the first temperature range for the first duration, the water and rice mixture is still not completely gelatinized, or only a small part is gelatinized, affecting the cooking of porridge.

[0128] In some embodiments, optionally, the gelatinization temperature of the water and rice mixture can be obtained through experimental measurement and input into the cooking device, or input into a server communicating with the cooking device, so that the cooking device can obtain it through the server.

[0129] In some embodiments, optionally, the control method of the cooking device further includes: obtaining the type of rice in the water and rice mixture; and finding the gelatinization temperature of the water and rice mixture according to the type of rice in the water and rice mixture.

[0130] It can be understood that the gelatinization temperature of the water and rice mixture is related to the type of rice in the water and rice mixture.

[0131] In the above embodiment, by defining that the upper limit value of the first temperature range is less than the first temperature, it is avoided that the water and rice mixture is directly cooked in the environment where the water and rice mixture maintains the first temperature range, affecting the preparation of porridge.

[0132] In some embodiments, optionally, the color of the water and rice mixture can be observed through experiments, and when the color of the water and rice mixture is milky white, it is considered that the current gelatinization degree of the water and rice mixture is not likely to stick to the inner wall of the stirring chamber. By recording the continuous duration of the environment where the water and rice mixture maintains the first temperature range, the calibration of the first duration is achieved.

[0133] In some embodiments, optionally, during the process of the heating device operating at the first power, the working state of the heating device is controlled according to the comparison result between the temperature of the water and rice mixture and the first temperature range.

[0134] Specifically, in the case where the temperature of the water and rice mixture is lower than the lower limit value of the first temperature range, the heating device is controlled to start heating; conversely, when the temperature of the water and rice mixture reaches the first temperature range, the heating device is controlled to stop heating.

[0135] Among them, that the temperature of the water and rice mixture reaches the first temperature range can be understood as that the temperature of the water and rice mixture is between the lower limit value and the upper limit value of the first temperature range.

[0136] In some embodiments, optionally, the heating device is disposed in contact with the stirring chamber so as to heat the water and rice mixture by heating the stirring chamber.

[0137] In some embodiments, optionally, the heating device is a heating tube.

[0138] In some embodiments, optionally, the cooking device further includes a temperature detection device for detecting the temperature value of the water and rice mixture.

[0139] In some embodiments, optionally, the value of the first power is between 100 watts and 500 watts.

[0140] In some embodiments, optionally, the value of the second power is between 600 watts and 1500 watts.

[0141] In some embodiments, optionally, before controlling the heating device to operate at the first power until the duration that the temperature of the water and rice mixture is in the first temperature range is greater than or equal to the first duration, it further includes: controlling the heating device to operate at the third power until the temperature of the water and rice mixture rises to the first temperature range; wherein, the third power is greater than the first power.

[0142] In the embodiment, by controlling the heating device to operate at the third power, so that the water and rice mixture can be quickly heated up to reach the first temperature range. In this process, compared with the solution of always heating at the first power, the embodiment of the present application can shorten the cooking duration of the porridge, thereby reducing the waiting time of the user, and thus improving the user experience.

[0143] In the above embodiment, the third power may be the same as or different from the second power. In the case where the third power is different from the second power, the third power may be less than the second power. In this process, it can make the water and rice mixture have a relatively slow heating-up rate during the heating process, so as to improve the accuracy of temperature measurement. By limiting that the third power is greater than the first power, it is to avoid too small a heating-up rate, resulting in too long a total cooking duration and affecting the user experience.

[0144] In some embodiments, optionally, the value of the third power ranges from 600 watts to 1500 watts. In some embodiments, optionally, during the process of controlling the heating device to operate at the third power, the control method further includes: when the temperature of the water and rice mixture rises by the second temperature value each time, controlling the stirring motor 206 of the cooking device to rotate at the first speed for the second duration; wherein, when the stirring motor 206 rotates, the stirring blade 208 of the cooking device rotates in the stirring chamber 202 to stir the water and rice mixture.

[0145] In this embodiment, by controlling the stirring motor 206 to rotate at the first speed for the second duration, the water and rice mixture is stirred by the rotation of the stirring motor 206, so that the temperatures of all parts in the water and rice mixture tend to be the same. During this process, the accuracy of measuring the temperature of the water and rice mixture can be improved during the operation of the heating device at the third power, thereby improving the accuracy of cooking control.

[0146] Specifically, by defining the second temperature value, during the process of heating the water and rice mixture by the heating device, the stirring motor does not rotate continuously, but rotates for a while and then stops for a while. During this process, while ensuring that the temperatures at all positions in the water and rice mixture tend to be the same, the operating duration of the stirring motor can be reduced, thereby extending the service life of the stirring motor.

[0147] In addition, since the stirring motor rotates for a while and then stops for a while, rather than rotating continuously, the power consumption of the cooking device can be reduced. At the same time, it is also convenient to reduce the noise generated during the operation of the cooking device and improve the user experience.

[0148] In some embodiments, optionally, the first speed and the second duration can be selected according to actual usage needs and will not be elaborated here.

[0149] In some embodiments, optionally, the second temperature value can be selected according to actual usage needs, such as 10 degrees Celsius, 5 degrees Celsius, or 3 degrees Celsius, or other values, and its specific value will not be elaborated here.

[0150] In some embodiments, optionally, the second duration is the continuous duration for which the stirring motor rotates at the first speed.

[0151] In some embodiments, optionally, the value of the first speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the second duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0152] In this embodiment, by defining that the value of the first rotation speed is greater than or equal to 1000 RPM, the rice in the water-rice mixture, that is, the food ingredients, can be separated from the bottom of the stirring chamber as the stirring motor rotates, avoiding excessive contact time with the bottom of the stirring chamber and preventing sticking to the bottom.

[0153] At the same time, by defining that the value of the first rotation speed is not higher than 4000 RPM, it is possible to avoid completely crushing the rice in the water-rice mixture, that is, the food ingredients, into powder when the rotation speed of the stirring motor is too high. When the value of the first rotation speed is not higher than 4000 RPM, the rice in the water-rice mixture can be beaten into smaller granular forms, such as granular forms the size of millet or 1 / 4 the size of rice grains, to ensure the taste of the cooked porridge-like food.

[0154] In addition, when the value of the first rotation speed is greater than or equal to 1000 RPM, it is possible to avoid the situation where the temperature of the water-rice mixture cannot tend to be the same due to too low a rotation speed. On the contrary, by defining that the value of the first rotation speed is not higher than 4000 RPM, it is possible to avoid excessive rotation speed, which increases the power consumption of the cooking device and generates relatively large noise.

[0155] In the above embodiment, by defining the second duration, the automatic control of the stirring motor can be realized, so that the stirring motor can be automatically started and stopped during the process of heating the water-rice mixture by the heating device.

[0156] In some embodiments, optionally, before controlling the heating device to operate at the third power until the temperature of the water-rice mixture rises to the first temperature range, it further includes: controlling the stirring motor of the cooking device to rotate at the second rotation speed for the third duration; wherein the first rotation speed is greater than or equal to the second rotation speed.

[0157] In this embodiment, by controlling the stirring motor to rotate at the second rotation speed for the third duration, during the rotation of the stirring motor, the stirring member can be driven to rotate, so as to stir up the rice in the water-rice mixture, thus separating it from the bottom wall of the stirring chamber and avoiding excessive contact time with the bottom of the stirring chamber and preventing sticking to the bottom. This provides a basis for subsequent heating at the third power. During this process, the sticking of the rice in the water-rice mixture to the bottom wall of the stirring chamber during heating at the third power can be improved.

[0158] In some embodiments, by defining that the second rotation speed is less than the first rotation speed, during the rotation of the stirring motor at the first rotation speed, a high rotation speed can be adopted to provide a relatively large force to stir the water-rice mixture. At the same time, during the rotation at the second rotation speed, a relatively gentle stirring method can be adopted to reduce the noise generated by stirring.

[0159] In some embodiments, the value range of the second rotational speed is the same as that of the first rotational speed, that is, the value of the second rotational speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM.

[0160] In the above embodiments, the third duration can be set according to actual usage needs and will not be elaborated here.

[0161] In some embodiments, optionally, the third duration is the duration during which the stirring motor rotates at the second rotational speed.

[0162] In some embodiments, optionally, the value of the third duration is between 1 second and 5 seconds.

[0163] In some embodiments, optionally, after controlling the heating device to operate until the boiling of the water and rice mixture ends, it further includes: controlling the stirring motor of the cooking device to rotate at a third rotational speed for a fourth duration.

[0164] In this embodiment, by controlling the stirring motor to rotate at the third rotational speed, the stirring member is driven to stir during the rotation of the stirring motor, so that the cooked porridge food is separated from the bottom wall of the stirring cavity.

[0165] During this process, the slight adhesion between the cooked porridge food and the bottom wall of the stirring cavity can be improved. Thus, it is convenient for the user to pour the porridge food out of the stirring cavity and also facilitates the cleaning after pouring the porridge food out of the stirring cavity, thereby improving the difficulty of pouring the porridge food and the cleaning difficulty of the stirring cavity.

[0166] In some embodiments, the fourth duration can be the duration during which the stirring motor continuously rotates at the third rotational speed, or the cumulative duration when the stirring motor rotates intermittently at the third rotational speed.

[0167] In some embodiments, optionally, the value of the third rotational speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the fourth duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0168] In some embodiments, optionally, the temperature value of the first temperature range is greater than or equal to 50 °C and less than or equal to 80 °C; and / or the value of the first duration is greater than or equal to 3 minutes and less than or equal to 15 minutes.

[0169] In this embodiment, the first temperature range can be determined according to the type of rice in the water and rice mixture. Specifically, a corresponding relationship between different rice types and different first temperature ranges is pre-established. Then, in the case of determining the rice type of the water and rice mixture placed in the stirring cavity, the first temperature range is obtained based on the above corresponding relationship.

[0170] In some embodiments, optionally, control the operation of the heating device until the boiling of the water and rice mixture is completed, which specifically includes: controlling the heating device to operate at a fourth power until the heating device operates at the fourth power for a fifth duration; wherein, the fourth power is less than or equal to the first power.

[0171] In this embodiment, by controlling the heating device to operate at the fourth power for the fifth duration, so that the rice and water mixture can be cooked thoroughly. During this process, the occurrence of half-cooked porridge can be reduced, thereby increasing the cooking success rate of porridge.

[0172] In some embodiments, optionally, the fifth duration can be the continuous duration of the heating device operating at the fourth power, or the cumulative duration when the heating device operates intermittently at the fourth power.

[0173] In the above embodiment, by limiting the fourth power to be not higher than the first power, it is possible to avoid the situation of the bottom of the cooked porridge sticking due to excessive power.

[0174] In some embodiments, optionally, the fourth power is greater than or equal to 100 watts and less than or equal to 500 watts; and / or the value of the fifth duration is greater than or equal to 10 minutes and less than or equal to 60 minutes.

[0175] In some embodiments, as Figure 3 shown, the control method of the cooking device includes:

[0176] Step 302, the user adds ingredients and starts cooking.

[0177] Step 304, stir at a low speed once to prevent sticking to the bottom during subsequent heating.

[0178] Specifically, control the motor to stir at a lower speed, that is, the second speed, such as 1000 RPM to 4000 RPM for a third duration, such as 1 second to 5 seconds.

[0179] Step 306, heat to temperature TI using high power P1.

[0180] Specifically, the high power P1 is also the third power, and the temperature TI is also the first temperature range.

[0181] Step 308, control the temperature at TI using low power P2 and maintain for t1 minutes to reduce sticking due to food gelatinization.

[0182] Specifically, the low power P2 is also the first power, and t1 is also the first duration.

[0183] Step 310, heat to boiling using high power P3.

[0184] Specifically, the high power P3 is also the second power.

[0185] Step 312, boil with a low power P4.

[0186] Specifically, the low power P4 is also the fourth power.

[0187] Step 314, stir once at a low speed to further improve sticking to the bottom.

[0188] Specifically, the low speed is also the third speed.

[0189] In this embodiment, by performing step 304, the ingredients are stirred at a low speed before heating to lift the ingredients off the chassis to avoid subsequent heating adhesion, but not crushed. By performing step 308, by controlling the temperature slightly higher than the initial gelatinization temperature of the rice, the ingredients start to gelatinize, and when gelatinizing, a lower power is used for heating so that the gelatinization reaction does not adhere to the chassis. The temperature control time is preset until the rice water turns milky white, that is, when the gelatinization degree is relatively high. At this time, when entering the subsequent boiling and simmering processes, it is not easy to stick to the bottom. By performing step 314, after the simmering is completed, the ingredients are stirred at a low speed to lift them off the chassis but not ground into rice paste to improve the slight adhesion during the process.

[0190] In some embodiments, as Figure 4 shown, the present invention provides a control device 400 for a cooking device. The cooking device includes a stirring chamber and a heating device. The stirring chamber is used to hold the water and rice mixture, and the heating device is used to heat the water and rice mixture. The control device includes: a first control unit 402, configured to control the heating device to operate at a first power until the duration that the temperature of the water and rice mixture is within a first temperature range is greater than or equal to a first duration; a second control unit 404, configured to control the heating device to operate at a second power until the water and rice mixture boils; a third control unit 406, configured to control the heating device to operate until the simmering of the water and rice mixture ends; wherein, when the water and rice mixture boils, the temperature of the water and rice mixture is a first temperature, the upper limit value of the first temperature range is less than the first temperature, the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, and the first power is less than the second power.

[0191] An embodiment of the present application proposes a control device 400 for a cooking device, which can realize the cooking of the water and rice mixture, and then cook porridge-like food. During this process, the problem of the porridge-like food sticking to the bottom after cooking can be improved. While improving the problem of the porridge-like food sticking to the bottom after cooking, it is convenient for the user to pour out the porridge and clean the cooking device. At the same time, the probability of the porridge sticking to the bottom is also reduced, and the success rate of porridge cooking is improved.

[0192] The embodiments of the present application are implemented based on the following principles. Specifically, in related embodiments, during the process of quickly boiling with high power, the water and rice mixture is rapidly gelatinized at high temperature. Due to the high power used, the temperature of the bottom plate of the stirring cavity is relatively high, and the gelatinized water and rice mixture is extremely likely to adhere to the inner wall of the stirring cavity. With subsequent heating, the adhesion becomes more serious, and even bottom burning occurs.

[0193] During this process, by controlling the heating device to operate at a first power lower than the second power, so that before the water and rice mixture is heated to boiling, the water and rice mixture is maintained in an environment of a first temperature range, enabling the water and rice mixture to basically complete gelatinization in this stage. Since the first power is less than the second power, the temperature of the inner wall of the stirring cavity can be reduced, making it less likely to stick to the bottom during the gelatinization stage of the water and rice mixture, thereby improving the problem of sticking to the bottom existing in the cooking of porridge-like foods.

[0194] In the above embodiment, by defining that the lower limit value of the first temperature range is higher than the gelatinization temperature of the water and rice mixture, it is avoided that due to the too low temperature of the water and rice mixture, gelatinization cannot occur, or after maintaining the first temperature range for the first duration, the water and rice mixture is still not completely gelatinized, or only a small part is gelatinized, which affects the cooking of porridge.

[0195] In some embodiments, optionally, the gelatinization temperature of the water and rice mixture can be obtained through experimental measurement and input into the cooking device or into a server communicating with the cooking device, so that the cooking device can obtain it through the server.

[0196] In some embodiments, optionally, it further includes: obtaining the type of rice in the water and rice mixture; and finding the gelatinization temperature of the water and rice mixture according to the type of rice in the water and rice mixture.

[0197] It can be understood that the gelatinization temperature of the water and rice mixture is related to the type of rice in the water and rice mixture.

[0198] In the above embodiment, by defining that the upper limit value of the first temperature range is less than the first temperature, it is avoided that the water and rice mixture is directly cooked in the environment where the water and rice mixture maintains the first temperature range, which affects the preparation of porridge.

[0199] In some embodiments, optionally, the color of the water and rice mixture can be observed through experiments, and when the color of the water and rice mixture is milky white, it is considered that the current gelatinization degree of the water and rice mixture is not likely to adhere to the inner wall of the stirring cavity. By recording the continuous duration of the environment where the water and rice mixture maintains the first temperature range, the calibration of the first duration is achieved.

[0200] In some embodiments, optionally, during the operation of the heating device at the first power, the operating state of the heating device is controlled according to the comparison result between the temperature of the water and rice mixture and the first temperature range.

[0201] Specifically, when the temperature of the water and rice mixture is lower than the lower limit value of the first temperature range, the heating device is controlled to start heating; conversely, when the temperature of the water and rice mixture reaches the first temperature range, the heating device is controlled to stop heating.

[0202] Wherein, the temperature of the water and rice mixture reaching the first temperature range can be understood as that the temperature of the water and rice mixture is between the lower limit value and the upper limit value of the first temperature range.

[0203] In some embodiments, optionally, before the duration of the control of the heating device operating at the first power until the temperature of the water and rice mixture is in the first temperature range is greater than or equal to the first duration, the first control unit 402 is further configured to: control the heating device to operate at the third power until the temperature of the water and rice mixture rises to the first temperature range; wherein, the third power is greater than the first power.

[0204] In the embodiment, by controlling the heating device to operate at the third power, so that the water and rice mixture can be quickly heated up to reach the first temperature range. In this process, compared with the solution of always heating at the first power, the embodiment of the present application can shorten the cooking duration of the porridge, thereby reducing the waiting time of the user, and thus improving the user experience.

[0205] In the above embodiment, the third power may be the same as or different from the second power. When the third power is different from the second power, the third power may be less than the second power. In this process, it can make the water and rice mixture have a relatively slow heating rate during the heating process, so as to improve the accuracy of temperature measurement. By limiting that the third power is greater than the first power, it is possible to avoid too small a heating rate, resulting in too long a total cooking duration and affecting the user experience.

[0206] In some embodiments, optionally, during the operation of the heating device at the third power, the first control unit 402 is further configured to: when the temperature of the water and rice mixture rises by the second temperature value each time, control the stirring motor of the cooking device to rotate at the first speed for the second duration; wherein, when the stirring motor rotates, the stirring blade of the cooking device rotates in the stirring cavity to stir the water and rice mixture.

[0207] In this embodiment, by controlling the stirring motor to rotate at the first rotation speed for the second duration, the water and rice mixture is stirred by the rotation of the stirring motor, so that the temperatures of all parts in the water and rice mixture tend to be the same. During this process, during the operation of the heating device at the third power, the accuracy of measuring the temperature of the water and rice mixture can be improved, thereby enhancing the precision of cooking control.

[0208] Specifically, by defining the second temperature value, during the process of heating the water and rice mixture by the heating device, the stirring motor does not rotate continuously, but rotates for a while and then stops for a while. During this process, while ensuring that the temperatures at all positions in the water and rice mixture tend to be the same, the running duration of the stirring motor can be reduced, thereby enhancing the service life of the stirring motor.

[0209] In addition, since the stirring motor rotates for a while and then stops for a while instead of rotating continuously, the power consumption of the cooking device can be reduced. At the same time, it is also convenient to reduce the noise generated during the operation of the cooking device and improve the user experience.

[0210] In some embodiments, optionally, the first rotation speed and the second duration can be selected according to actual usage needs, and will not be elaborated here.

[0211] In some embodiments, optionally, the second temperature value can be selected according to actual usage needs, such as 10 degrees Celsius, 5 degrees Celsius, or 3 degrees Celsius, or other values, and its specific value will not be elaborated here.

[0212] In some embodiments, optionally, the second duration is the continuous duration of the stirring motor rotating at the first rotation speed.

[0213] In some embodiments, optionally, the value of the first rotation speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the second duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0214] In this embodiment, by defining that the value of the first rotation speed is greater than or equal to 1000 RPM, the rice in the water and rice mixture, that is, the ingredients, can be separated from the bottom of the stirring cavity with the rotation of the stirring motor, avoiding the situation of sticking to the bottom due to too long contact time with the bottom of the stirring cavity.

[0215] At the same time, by defining that the value of the first rotation speed is not higher than 4000 RPM, it is possible to avoid completely crushing the rice in the water and rice mixture, that is, the ingredients, into powder when the rotation speed of the stirring motor is too high. When the value of the first rotation speed is not higher than 4000 RPM, the rice in the water and rice mixture can be beaten into smaller granular shapes, such as granular shapes the size of millet or 1 / 4 the size of a rice grain, to ensure the taste of the porridge-like food obtained by cooking.

[0216] In addition, when the value of the first rotation speed is greater than or equal to 1000 RPM, it is possible to avoid the situation where the temperature of the water and rice mixture cannot tend to be the same due to too low a rotation speed. On the contrary, by limiting the value of the first rotation speed to not be higher than 4000 RPM, it is possible to avoid an excessive rotation speed, which increases the power consumption of the cooking device and generates a relatively large noise at the same time.

[0217] In the above embodiment, by limiting the second duration, the automatic control of the stirring motor can be realized, so that the stirring motor can be automatically started and stopped during the process of the heating device heating the water and rice mixture.

[0218] In some embodiments, optionally, before the temperature of the water and rice mixture rises to the first temperature range, the first control unit 402 is further configured to control the stirring motor of the cooking device to rotate at a second rotation speed for a third duration while controlling the heating device to operate at a third power; wherein, the first rotation speed is greater than or equal to the second rotation speed.

[0219] In this embodiment, by controlling the stirring motor to rotate at the second rotation speed for the third duration, during the rotation of the stirring motor, the stirring member is driven to rotate, so as to stir up the rice in the water and rice mixture, so as to separate from the bottom wall of the stirring cavity and avoid contacting the bottom of the stirring cavity for too long and sticking to the bottom. This provides a basis for subsequent heating with the third power. During this process, the sticking of the rice in the water and rice mixture to the bottom wall of the stirring cavity during the heating process by the heating device with the third power can be improved.

[0220] In some embodiments, by limiting the second rotation speed to be less than the first rotation speed, during the process of the stirring motor rotating at the first rotation speed, it can rotate at a high speed, thereby providing a relatively large force to stir the water and rice mixture. At the same time, during the process of rotating at the second rotation speed, it can stir in a relatively gentle manner, thereby reducing the noise generated by the stirring.

[0221] In the above embodiment, the third duration can be selected according to actual usage needs and will not be elaborated here.

[0224] In this embodiment, the stirring motor is controlled to rotate at a third rotational speed, so as to drive the stirring member to stir during the rotation of the stirring motor, so that the cooked porridge-like food is separated from the bottom wall of the stirring cavity.

[0225] During this process, the slight adhesion between the cooked porridge-like food and the bottom wall of the stirring cavity can be improved. Furthermore, while facilitating the user to pour the porridge-like food out of the stirring cavity, it is also convenient for cleaning after pouring the porridge-like food out of the stirring cavity, thereby improving the difficulty of pouring the porridge-like food and the cleaning difficulty of the stirring cavity.

[0226] In some embodiments, the fourth duration may be the continuous duration of the stirring motor rotating at the third rotational speed, or the cumulative duration when the stirring motor rotates intermittently at the third rotational speed.

[0227] In some embodiments, optionally, the value of the third rotational speed is greater than or equal to 1000 RPM and less than or equal to 4000 RPM; and / or the value of the fourth duration is greater than or equal to 1 second and less than or equal to 5 seconds.

[0228] In some embodiments, optionally, the temperature value of the first temperature range is greater than or equal to 50 degrees Celsius and less than or equal to 80 degrees Celsius; and / or the value of the first duration is greater than or equal to 3 minutes and less than or equal to 15 minutes.

[0229] In this embodiment, the first temperature range can be determined according to the type of rice in the water-rice mixture. Specifically, a corresponding relationship between different rice types and different first temperature ranges is pre-constructed. Then, in the case of determining the rice type of the water-rice mixture placed in the stirring cavity, the first temperature range is obtained based on the above corresponding relationship.

[0230] In some embodiments, optionally, the third control unit 406 is specifically configured to: control the heating device to operate at a fourth power until the heating device operates at the fourth power for a fifth duration; wherein the fourth power is less than or equal to the first power.

[0231] In this embodiment, by controlling the heating device to operate at the fourth power for the fifth duration, so that the rice-water mixture can be cooked thoroughly. During this process, the occurrence of undercooked porridge-like food can be reduced, thereby increasing the cooking success rate of the porridge-like food.

[0232] In some embodiments, optionally, the fifth duration may be the continuous duration of the heating device operating at the fourth power, or the cumulative duration when the heating device operates intermittently at the fourth power.

[0233] In the above embodiment, by limiting the fourth power to be not higher than the first power, so as to avoid the situation that the cooked porridge-like food sticks to the bottom due to excessive power.

[0234] In some embodiments, optionally, the fourth power is greater than or equal to 100 watts and less than or equal to 500 watts; and / or the value of the fifth duration is greater than or equal to 10 minutes and less than or equal to 60 minutes.
