Description

Technical Field

[0001] The present invention belongs to the technical field of cooking appliances, and in particular to a cooking control method of a cooking appliance, a cooking appliance and a medium. Background Art

[0002] As the most common staple food in China, rice is accepted by most consumers. Improving the sweetness of rice is an urgent problem to be solved in order to improve the taste of rice. Rice can be perceived as sweet because, as a starch-based food, the starch undergoes thermal degradation during cooking to produce small-molecule sugars. When chewed by humans, it is degraded into small-molecule sugars such as maltose due to the presence of substances such as salivary amylase, which makes it perceived as sweet by humans. Cooking rice in cooking utensils such as rice cookers is in a high temperature and high humidity environment, which is conducive to the Maillard reaction between small-molecule sugars in rice and substances such as proteins and amino acids, thereby consuming small-molecule sugars in rice, and ultimately causing the sweetness of rice to decrease. Other starch-containing ingredients also have the problem of Maillard reaction during cooking, resulting in a decrease in sweetness.

[0003] In order to increase the sweetness of starchy ingredients such as rice after cooking, it is necessary to collect the liquid containing dissolved small molecule sugar substances to avoid the Maillard reaction in the cooking chamber and the loss of sweetness. Since the cooking utensils in the related technology cannot quickly and continuously collect liquid during the cooking process, it is easy to cause the loss of sweet components.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present invention provides a cooking control method for a cooking appliance, which can be executed by the cooking appliance itself or by an external device interacting with the cooking appliance. The cooking appliance can be an electric rice cooker, an electric pressure cooker, a steamer or a steam oven, etc.

[0034] Figure 1 FIG. 2 shows a schematic diagram of a cooking appliance according to some embodiments of the present invention. Figure 1 As shown, the cooking device includes a cooking cavity 10 and a liquid retaining device 20. The cooking cavity 10 is used to accommodate food, and the liquid retaining device 20 is disposed in the cooking cavity 10. At least one through hole is provided in the liquid retaining device 20, and the through hole is a passage for the liquid in the cooking cavity 10 to flow into and out of the liquid retaining device 20. The liquid collected in the liquid retaining device can flow back into the cooking cavity through the through hole under the action of gravity. The liquid retaining device 20 can be supported by the cooking cavity 10 or fixed to the upper cover of the cooking device.

[0035] The cooking control method of the cooking appliance provided in the embodiment of the present invention is applied to the case where the cooking cavity includes starch-containing food and liquid. In the embodiment of the present invention, the starch-containing food in the cooking cavity may include cereal food such as rice and / or brown rice, so it is applicable to the process of cooking rice or porridge of cereal food. The starch-containing food may also be food such as noodles and steamed buns.

[0036] Figure 2 FIG. 1 is a flow chart showing a cooking control method of a cooking appliance according to some embodiments of the present invention. Figure 2 As shown, the cooking control method of the cooking appliance includes steps S101 to S102.

[0037] S101, performing a first heating step of heating a cooking cavity at a first power, so that liquid in the cooking cavity enters a liquid retaining device.

[0038] In some embodiments, before performing a first heating step of heating the cooking cavity at a first power, it may also include: performing a preheating step of heating the cooking cavity at a third power; after performing the preheating step to bring the cooking cavity into a boiling state, performing the first heating step of heating the cooking cavity at the first power again.

[0039] In some embodiments, in response to a start command for instructing the cooking appliance to start the current cooking, the cooking appliance is controlled to start a preheating step of heating the cooking cavity. The start command may be triggered by a user manually starting the current cooking, or by the arrival of a scheduled time. In the current cooking process, before the preheating step of heating the cooking cavity at the third power is performed, other cooking steps may be performed, such as a water adding step, a standing step, etc.

[0040] The preheating step is used to heat the cooking cavity to a boiling state. The third power can use the rated power of the cooking appliance or a preset power close to the rated power to quickly heat the cooking cavity to a boiling state to improve cooking efficiency. In some embodiments, the preset power can be set to a fixed power of 85% or more of the rated power.

[0041] Since the cooking cavity enters a boiling state, part of the liquid in the cooking cavity can enter the liquid retaining device. Therefore, when liquid begins to enter the liquid retaining device, it indicates that the cooking cavity has entered a boiling state, and then the first heating step of heating the cooking cavity at a first power is entered.

[0042] In some embodiments, during the preheating step, temperature measurement data of the location of the liquid retention device is obtained; whether liquid begins to enter the liquid retention device is determined based on the temperature measurement data; after liquid begins to enter the liquid retention device, it indicates that the cooking cavity has entered a boiling state, and then a first heating step of heating the cooking cavity at a first power is entered.

[0043] In some embodiments, determining whether liquid begins to enter the liquid retention device based on temperature measurement data may include: determining the current temperature and current temperature rise of the location of the liquid retention device based on the temperature measurement data; if the current temperature is greater than or equal to a preset temperature threshold, and the current temperature rise is greater than or equal to the preset temperature rise threshold, it is determined that liquid begins to enter the liquid retention device.

[0044] In other implementations, determining whether liquid begins to enter the liquid retention device based on temperature measurement data may include: determining a current temperature of the location where the liquid retention device is located based on the temperature measurement data, and if the current temperature of the location where the liquid retention device is located is greater than or equal to a preset temperature threshold, determining that liquid begins to enter the liquid retention device.

[0045] In some other embodiments, determining whether liquid begins to enter the liquid retention device based on temperature measurement data may include: determining a current temperature rise at the location of the liquid retention device based on the temperature measurement data; if the current temperature rise is greater than or equal to a preset temperature rise threshold, determining that liquid begins to enter the liquid retention device.

[0046] In some embodiments, the current temperature rise is a unit temperature rise (e.g., the temperature rise per second), and the preset temperature threshold is set according to the boiling point of the liquid under the pressure in the cooking cavity and is less than the boiling point of the liquid under the pressure in the cooking cavity. The boiling point of the liquid under the pressure in the cooking cavity minus 5° C. can be used as the preset temperature threshold. The preset temperature rise threshold can be set according to the unit temperature rise when the liquid boils under the pressure in the cooking cavity.

[0047] It is understandable that, taking a cooking appliance without pressure cooking (such as an electric rice cooker) as an example, the preset temperature threshold can be set to 95°C or a similar value, and the preset temperature rise threshold can be set to 5°C / s or a similar value. Because the temperature and unit temperature rise when liquid begins to enter the liquid retention device of different cooking appliances may be different, the preset temperature threshold and the preset temperature rise threshold may be measured in advance according to experiments.

[0048] In some embodiments, the cooking appliance includes an upper cover, and a first temperature detection device installed on the upper cover is arranged opposite to the liquid retaining device, and is used to detect the temperature of the position where the liquid retaining device is located. In other embodiments, a second temperature detection device is installed at the liquid retaining device, and is used to detect the temperature of the position where the liquid retaining device is located. Therefore, the temperature measurement data of the position where the liquid retaining device is located can be obtained through the first temperature detection device and / or the second temperature detection device.

[0049] In some embodiments, the heating power of the cooking appliance is adjusted from the third power to the first power by power adjustment, so that the preheating step ends and the first heating step begins. The first power is a fixed power that is preset and is less than the rated power of the cooking appliance.

[0050] Step S102: performing a second heating step of heating the cooking cavity with a second power so that the liquid in the cooking cavity enters the liquid retaining device, wherein the second power is greater than the first power, and the second power and the first power are negatively correlated with the amount of liquid in the cooking cavity.

[0051] In some embodiments, the heating duration of the first heating step and the second heating step is a preset fixed duration, the actual amount of liquid in the liquid retaining device or the amount of liquid in the cooking cavity is obtained at the target time of executing the first heating step, and the second power is determined according to the actual amount of liquid in the liquid retaining device or the amount of liquid in the cooking cavity. It can be understood that the target time may be the time when the first heating step ends or a time close to the end of the first heating step, and the smaller the actual amount of liquid in the liquid retaining device or the amount of liquid in the cooking cavity obtained at the target time, the greater the second power used in the second heating step of the current cooking.

[0052] In other embodiments, the second power is a preset fixed power, the second power used in different cooking times is the same, and the heating time of the first heating step and the second heating step is a preset fixed time. Then, during the execution of the first heating step, the current amount of liquid in the cooking cavity is obtained in real time, and when the current amount of liquid is less than the preset lower threshold, the first heating step is terminated and the second heating step of heating the cooking cavity with the preset second power is entered.

[0053] In some embodiments, both the first heating step and the second heating step use a single power to heat the cooking cavity, that is, the first heating step is to continuously heat the cooking cavity at a first power, and the second heating step is to continuously heat the cooking cavity at a second power.

[0054] Figure 3a Schematic diagrams of the first heating step and the second heating step according to some embodiments of the present invention are shown. Figure 3aAs shown, in the first heating step ①, the cooking cavity is continuously heated with the first power P1 for a heating time of T1, so that the liquid in the cooking cavity is in a cycle of entering and flowing out of the liquid retaining device; as the current cooking progresses, the amount of liquid in the cooking cavity decreases, and it becomes more difficult for the liquid in the cooking cavity to enter the liquid retaining device, and then the second heating step ② is entered. In the second heating step ②, the cooking cavity is continuously heated with the second power P2 for a heating time of T2, so that the liquid in the cooking cavity can continue to be in a cycle of entering and flowing out of the liquid retaining device, wherein P2>P1.

[0055] In other embodiments, both the first heating step and the second heating step heat the cooking cavity in a power modulation mode of alternating heating with two powers, wherein the first power is the larger power value of the two powers used in the first heating step, and the second power is the larger power value of the two powers used in the second heating step. Before performing the second heating step of heating the cooking cavity with the second power, the method may further include: determining the power-on time of the second power according to the actual liquid amount in the liquid retaining device or the liquid amount in the cooking cavity obtained at the target time of performing the first heating step, wherein the smaller the actual liquid amount in the liquid retaining device or the liquid amount in the cooking cavity, the larger the power-on time of the second power.

[0056] The smaller power value used in the second heating step can be a preset fixed power, or can be determined based on the actual amount of liquid in the liquid retention device obtained at the target time of executing the first heating step, wherein the smaller the actual amount of liquid, the larger the smaller power value used in the second heating step.

[0057] The power-on time of the smaller power value used in the second heating step can be a preset value, wherein it can be preset to be the same as the power-on time of the smaller power value used in the first heating step, or it can be determined based on the actual amount of liquid in the liquid retention device or the amount of liquid in the cooking cavity obtained at the target time of executing the first heating step. The smaller the actual amount of liquid in the liquid retention device or the amount of liquid in the cooking cavity, the greater the power-on time of the smaller power value used in the second heating step.

[0058] Figure 3b Schematic diagrams of the first heating step and the second heating step according to other embodiments of the present invention are shown. Figure 3b As shown, the first heating step is performed according to the first power modulation cycle C1=t A1 +t B1 First, the larger power value of the two powers (that is, the first power P1) is used for the working time t A1, so that the liquid in the cooking chamber enters the liquid interception device, and then works at the smaller power value P1' for a time t B1 , so that the liquid in the liquid retaining device flows back into the cooking chamber, and the process is repeated alternately until the first heating step is completed. The second heating step is performed according to the second power adjustment cycle C2=t A2 +t B2 , first use the larger power value of the two powers (that is, the second power P2) for a working time of t A2 , so that the liquid in the cooking chamber enters the liquid interception device, and then works at the smaller power P2' for a time t B2 , so that the liquid in the liquid retaining device flows back into the cooking cavity, and the process is repeated alternately until the second heating step is completed.

[0059] In each power adjustment cycle of the first heating step ①, the heating time at P1 is t A1 , so that the liquid enters the liquid retention device, and then P1 ’ Power working B1 , so that the liquid flows back into the cooking chamber, and the total duration of the first power adjustment cycle is T1; where P1>P1 ’ ≥0. As the current cooking progresses, the amount of liquid in the cooking chamber decreases, and it becomes more difficult for the liquid to enter the liquid retaining device, and the second heating step ② is entered. In each power adjustment cycle of the second heating step ②, the heating power is P2. A2 time, allowing the liquid to enter the liquid retention device, and then P2 ’ Power working B2 time, so that the liquid flows back into the cooking chamber, and the total duration of the second power adjustment cycle is T2; where P2>P2 ’ ≥0, and P2≥P1.

[0060] In some embodiments, the first power P1 used in the first heating step is greater than 1 / 2 of the rated power or greater than 600 W. The second power P2 used in the second heating step is greater than 3 / 4 of the rated power or greater than 900 W.

[0061] As the current cooking progresses, the liquid in the cooking cavity will gradually be absorbed by the starch-containing food, resulting in a decrease in the total amount of liquid in the cooking cavity and the liquid retaining device, making it more difficult for the liquid in the cooking cavity to flow into the liquid retaining device. After the first heating step is completed, the second heating step of heating the cooking cavity with a second power greater than the first power can increase the boiling degree in the cooking cavity, so that even if the amount of liquid in the cooking cavity is reduced, it can still enter the liquid retaining device, thereby achieving continuous and rapid collection of liquid, making it easier to collect liquid.

[0062] In some embodiments, after performing a first heating step of heating the cooking cavity at a first power, the method may further include: performing N heating steps of heating the cooking cavity, wherein the second heating step belongs to one of the N heating steps, and N is an integer greater than 1. For each of the N heating steps, at the target time of performing the current heating step, the actual amount of liquid in the liquid retaining device is obtained, and the heating power required for the next heating step is determined according to the actual amount of liquid in the liquid retaining device, so that the heating power used in the first heating step and the N heating steps after the first heating step tends to increase over time, so as to achieve rapid and continuous collection of liquid as the amount of liquid in the cooking cavity and the liquid retaining device decreases and the boiling degree increases.

[0063] In some embodiments, the heating time of the first heating step and each of the N heating steps is relatively long, for example, each heating step lasts for more than 1 minute, and the current heating step can be timed, and the target time can be the time when the timing of the current heating step ends or a time close to the end of the timing. It is understandable that the heating time of the first heating step and each of the N heating steps can be a preset fixed value, and the preset heating time for each heating step can be the same or different.

[0064] In other embodiments, after the first heating step of heating the cooking cavity at the first power is performed, the actual amount of liquid in the liquid retaining device is detected in real time according to a preset detection frequency, and after each detection of the actual amount of liquid in the liquid retaining device, the heating power is re-determined according to the actual amount of liquid in the liquid retaining device detected at the current time, and the next heating step is performed at the re-determined heating power, and the target time is the time when the current heating step is performed. Thus, the heating power can be dynamically adjusted according to the amount of liquid in the liquid retaining device in real time.

[0065] In some embodiments, the first heating step and the N heating steps both use a single power to heat the cooking cavity. In other embodiments, the first heating step and the N heating steps both use a power modulation method of alternating two powers to heat the cooking cavity.

[0066] In the case where the cooking chamber is heated in the first heating step and the N heating steps in a power modulation mode of alternating heating with two powers, any one of the following implementation modes may be used to obtain the actual amount of liquid in the liquid retaining device at the target time of executing the current heating step, and determine the heating power required for the next heating step according to the actual amount of liquid in the liquid retaining device:

[0067] Embodiment 1: In N heating steps, one heating step is one power regulation cycle, the actual amount of liquid in the liquid retaining device is detected in the current regulation cycle, and the two powers required for the next power regulation cycle are determined according to the actual amount of liquid in the liquid retaining device detected in the current regulation cycle. It can be understood that the actual amount of liquid in the liquid retaining device can be detected at the end of the current power regulation cycle or when it is close to the end.

[0068] Embodiment 2: In N heating steps, each heating step includes a plurality of power modulation cycles. The actual amount of liquid in the liquid retaining device is detected in the last power modulation cycle of the current heating step, and two powers required for the next heating step are determined according to the actual amount of liquid in the liquid retaining device detected in the last power modulation cycle of the current heating step, so that the two powers are used alternately to heat the cooking cavity in the next heating step.

[0069] In some embodiments, obtaining the actual amount of liquid in the liquid retention device at the target time of executing the current heating step includes: obtaining the weight and / or volume of the liquid retention device at the target time of executing the current heating step; and determining the actual amount of liquid in the liquid retention device based on the weight and / or volume of the liquid retention device.

[0070] In some embodiments, the current weight of the liquid retention device can be obtained by weighing the liquid retention device, where the current weight is the sum of the body weight of the liquid retention device and the weight of the liquid in the liquid retention device; based on the difference between the current weight of the liquid retention device and the body weight of the liquid retention device, the weight of the liquid in the liquid retention device is determined as the actual amount of liquid in the liquid retention device.

[0071] In other embodiments, the current volume of the liquid retention device can be determined by optical signal recognition methods such as radar ranging or infrared ranging, as the actual amount of liquid in the liquid retention device, and the current volume is the volume of the liquid in the liquid retention device. In still other embodiments, the weight of the liquid in the liquid retention device can also be determined based on the current volume as the actual amount of liquid in the liquid retention device.

[0072] In some embodiments, determining the heating power required for the next heating step based on the actual amount of liquid in the liquid retention device obtained at the target time of executing the current heating step may include: if the actual amount of liquid in the liquid retention device is less than the preset expected amount of liquid, increasing the power based on the heating power used in the current heating step to obtain the heating power required for the next heating step; if the current amount of liquid in the liquid retention device is greater than the expected amount of liquid, reducing the power based on the heating power used in the current heating step to obtain the heating power required for the next heating step.

[0073] In some embodiments, increasing the power based on the heating power used in the current heating step may be increasing the power according to a fixed increment. In some embodiments, decreasing the power based on the heating power used in the current heating step may be decreasing the heating power used in the second heating step according to a fixed decrement.

[0074] In other embodiments, increasing the power based on the heating power used in the current heating step may be: increasing the power based on the difference between the actual liquid amount and the expected liquid amount based on the heating power used in the current heating step. It is understandable that the greater the difference between the actual liquid amount and the expected liquid amount, the greater the increment when increasing the power based on the heating power used in the current heating step.

[0075] In other embodiments, reducing the power based on the heating power used in the current heating step may be: reducing the power based on the difference between the actual liquid amount and the expected liquid amount based on the heating power used in the current heating step. It is understandable that the greater the difference between the actual liquid amount and the expected liquid amount, the greater the reduction in power when reducing the power based on the heating power used in the current heating step.

[0076] In other embodiments, determining the heating power required for the next heating step based on the actual amount of liquid in the liquid retention device may include: determining the heating power required for the next heating step based on pre-established correspondence data and the actual amount of liquid in the liquid retention device, the pre-established correspondence data being the correspondence between the liquid amount and the power.

[0077] In some embodiments, the correspondence data is the correspondence between each pre-divided liquid volume interval and the power. From the pre-divided liquid volume intervals, the first liquid volume interval where the actual liquid volume in the liquid retention device is located is determined; according to the correspondence data, the power matching the first liquid volume interval is obtained as the heating power required for the next heating step.

[0078] In other embodiments, the corresponding relationship data is a continuous mapping relationship between the liquid amount and the power, and the power matching the actual liquid amount in the liquid retaining device is obtained according to the continuous mapping relationship as the heating power required for the next heating step.

[0079] It can be understood that, when the first heating step and the N heating steps all heat the cooking chamber in a power modulation method of alternating heating with two powers, when the power is increased on the basis of the heating power used in the current heating step, only the larger power value of the two powers may be increased, or both powers may be increased, and when the power is reduced on the basis of the heating power used in the current heating step, only the larger power value of the two powers may be reduced, or both powers may be reduced.

[0080] In some embodiments, when the cooking appliance heats the cooking cavity in N heating steps according to the power adjustment cycle and alternating between two powers, after obtaining the actual amount of liquid in the liquid retention device at the target time of executing the current heating step, the method may also include: determining the first power turn-on time required for the next heating step according to the actual amount of liquid in the liquid retention device, and keeping the second power turn-on time unchanged; or determining the first power turn-on time and the second power turn-on time required for the next heating step according to the actual amount of liquid in the liquid retention device.

[0081] It can be understood that the first power-on time is the power-on time of the larger power value of the two powers used in the next heating step, and the second power-on time is the power-on time of the smaller power value of the two powers used in the next heating step.

[0082] In some embodiments, determining the first power-on time required for the next heating step based on the actual amount of liquid in the liquid retention device may include: if the actual amount of liquid in the liquid retention device is less than the expected amount of liquid, adding time to the first power-on time used in the current heating step to obtain the first power-on time required for the next heating step; if the current amount of liquid in the liquid retention device is greater than the expected amount of liquid, reducing time based on the first power-on time used in the current heating step to obtain the first power-on time required for the next heating step.

[0083] In some embodiments, determining the second power-on time required for the next heating step based on the actual amount of liquid in the liquid retention device may include: if the actual amount of liquid in the liquid retention device is less than the expected amount of liquid, adding time to the second power-on time used in the current heating step to obtain the second power-on time required for the next heating step; if the current amount of liquid in the liquid retention device is greater than the expected amount of liquid, reducing time based on the second power-on time used in the current heating step to obtain the second power-on time required for the next heating step.

[0084] It can be understood that when the first power-on time and the second power-on time are increased, they can be increased according to a fixed increment, or they can be increased according to the difference between the actual liquid volume and the expected liquid volume. The larger the difference, the greater the increase in the first power-on time and the second power-on time.

[0085] It can be understood that when reducing the first power-on time and the second power-on time, the reduction can be based on a fixed amount or based on the difference between the actual liquid volume and the expected liquid volume. The larger the difference, the greater the reduction in the first power-on time and the second power-on time.

[0086] In other embodiments, it is not necessary to determine the heating power required for the next heating step according to the actual amount of liquid in the liquid retaining device, but a heating power is preset for each of the N heating steps, wherein the closer the heating step is to the first heating step among the N heating steps, the greater the preset heating power is, so that the heating power used for the first heating step and the N heating steps is increased in steps. It is understandable that for each of the N heating steps, the heating power required for the heating step is determined according to the preset first mapping data, wherein the first mapping data includes the heating powers preset for the N heating steps.

[0087] In some embodiments, in the case where the cooking cavity is heated in a power modulation mode of alternating heating with two powers in the first heating step and each of the N heating steps, each heating step is to alternately heat the cooking cavity according to the two powers preset for the heating step and the first power on time and the second power on time corresponding to the two powers. For each of the N heating steps, the first power on time required for the heating step is obtained according to the preset second mapping data, or the first power on time and the second power on time required for the heating step are obtained according to the preset second mapping data, and the first power on time is the power on time of the larger power value of the two powers used in the heating step. The second power on time is the power on time of the smaller power value of the two powers used in the current heating step.

[0088] It is understandable that the first heating step and the N heating steps together constitute a liquid collection process that can collect liquid from the cooking cavity to the soup liquid interception device. After the liquid collection process is completed, other cooking steps can also be performed, such as entering the stewing step after the liquid collection process is completed.

[0089] In some embodiments, a total time threshold may be preset for the liquid collection process, and the liquid collection process is terminated when the total execution time of the first heating step and the N heating steps reaches the preset total time threshold. In other embodiments, the liquid collection process is terminated when the heating power used to execute the current heating step reaches the rated power and no liquid still enters the liquid interception device. In still other embodiments, the N heating steps and their heating times are preset, and the liquid collection process is terminated when the heating time of the last heating step among the N heating steps ends.

[0090] In order to facilitate understanding of the cooking control method of the cooking utensil provided in the embodiment of the present invention, the following is an exemplary description taking the cooking utensil as an electric rice cooker and the scenario of cooking rice in the electric rice cooker as an example, but it is not intended to limit the embodiment of the present invention:

[0091] Example 1:

[0092] Figure 4a FIG. 1 shows an example of the power of the first heating step and the second heating step in a rice cooker cooking scene. Figure 4a As shown: first, put the mixture of rice and water into the cooking chamber of the electric rice cooker and start heating to a boiling state; then, take 16s as the power adjustment cycle, in each power adjustment cycle, first heat with 1200W for 8s, so that the rice soup enters the liquid retention device, then work with 0W power for 8s, so that the rice soup flows out of the liquid retention device and enters the rice-water system in the cooking chamber, and repeat the power adjustment cycle, the total time is 3min; then, take 16s as the power adjustment cycle, in each power adjustment cycle, heat with 1200W for 12s, so that the rice soup enters the liquid retention device, then heat with 100W for 4s, so that the rice soup flows out of the liquid retention device and enters the rice-water system in the cooking chamber, and repeat the power adjustment cycle, the total time is 8min. Continue to adjust the two powers and the power on time until the execution time of the second heating step reaches the preset total heating time, and the second heating step ends.

[0093] Example 2:

[0094] Figure 4b FIG. 2 shows an example of the power of the first heating step and the second heating step in a rice cooker cooking scene. Figure 4b As shown, first, a mixture of rice and water is placed in the cooking chamber of the rice cooker and heated to a boiling state; then, the rice soup is heated at 600 W for 3 minutes, so that the rice soup is in a cycle of entering and flowing out of the liquid retention device; then, the rice soup is heated at 900 W for 8 minutes, so that the rice soup continues to be in a cycle of entering and flowing out of the liquid retention device; the power is continuously adjusted according to the preset setting until the execution time of the second heating step reaches the preset total heating time, and the second heating step ends.

[0095] Example 3:

[0096] First, put the mixture of rice and water into the cooking chamber of the rice cooker and start heating it to a boiling state; then, identify the amount of rice soup in the liquid retention device, assuming it is 10 ml, compare the difference between the amount of rice soup in the liquid retention device and the expected amount of rice soup 10 mL, which is 10 mL, and reduce the power to 600 W. As cooking progresses, the amount of rice soup in the cooking chamber decreases, and it becomes more difficult for the rice soup to enter the liquid retention device, resulting in the amount of rice soup being reduced to 9 mL. The difference between the amount of rice soup in the liquid retention device and the expected amount of rice soup 10 mL is -1 mL, and the power is increased to 700 W; continue to adjust the power according to the amount of rice soup in the liquid retention device until no liquid enters the liquid retention device when the power is adjusted to the rated power, and the second heating step ends.

[0097] According to one or more embodiments of the present invention, the liquid in the cooking cavity can still enter the liquid retaining device even if it is reduced, thereby realizing rapid and continuous collection of liquid from the cooking cavity to the liquid retaining device during the cooking process.

[0098] Furthermore, since the present invention realizes rapid and continuous collection of liquid to the liquid retaining device, it is easier to collect liquid from the cooking cavity to the liquid retaining device.

[0099] In some embodiments, the temperature of the liquid in the cooking cavity is higher than the temperature of the liquid in the liquid retention device. Because the liquid retention device does not directly contact the heating component, the temperature of the liquid in the liquid retention device will be lower than the temperature of the liquid in the cooking cavity, so that the boiling degree in the liquid retention device is lower than the boiling degree in the cooking cavity, thereby reducing the degree of Maillard reaction between small molecule sugar substances and substances such as proteins and amino acids, reducing the consumption of small molecule sugar substances during the cooking process, thereby increasing the content of small molecule sugar substances in starch-containing food after cooking, and can improve the sweetness of food cooked with starch-containing food by the cooking utensil.
