Rice, as the most commonly consumed staple food in China, is made possible by rice cooking appliances that can be programmed to cook delicious rice, making them an indispensable household kitchen appliance.

[0003] When using rice cookers or other rice cooking equipment, rice goes through several cooking stages, including soaking to absorb water, heating to a boil, maintaining the boil, and simmering. However, most rice cooking equipment uses a standard cooking program under the same function.

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0040] The rice cooking method provided in this application can be applied to a rice cooking device, which includes a controller, a heating unit, and a temperature detection device. The temperature detection device is used to detect the temperature value inside or at the bottom of the rice cooking device. The controller is connected to the temperature detection device to obtain the temperature value inside or at the bottom of the rice cooking device detected by the temperature detection device, and controls the heating unit according to the rice cooking method provided in this embodiment.

[0041] In one embodiment, a rice cooking method is provided, illustrated by an example of the method applied to a controller of a rice cooking device. It is understood that the rice cooking process corresponding to the rice cooking method provided in this application includes four cooking stages: soaking, heating, first boiling, second boiling, and simmering. Upon receiving a user's instruction to start cooking, the controller controls the heating unit to execute the standard cooking parameters corresponding to the four cooking stages sequentially. The cooking parameters for each stage may include, but are not limited to, at least one of the following: heating power value of the heating unit, heating duration, heat preservation duration, temperature threshold, and temperature range.

[0042] In one embodiment, such as Figure 1 As shown, the method includes steps 102 to 104. Wherein:

[0043] Step 102: After the rice cooking equipment enters the first boiling stage, determine the relevant temperature parameters inside the rice cooking equipment in real time.

[0044] Specifically, after entering the first boiling stage, the temperature-related parameters within the rice cooking equipment are determined in real time. These parameters include, but are not limited to, parameters related to the temperature or temperature changes within the rice cooking equipment. The temperature within the rice cooking equipment can include a first temperature detected by the bottom temperature sensor and a second temperature detected by the top temperature sensor. The temperature change-related parameters can be either the first or second temperature change-related parameters. Then, based on these temperature-related parameters, it is determined whether to end the first boiling stage and proceed to the second boiling stage.

[0045] Step 104: When the conditions for entering the second boiling stage are met according to the temperature-related parameters, the second boiling stage is entered and the temperature-related parameters in the rice cooking equipment are controlled to be maintained within the preset boiling temperature range; wherein, when the conditions for entering the second boiling stage are met, the free water in the rice cooking equipment has evaporated completely.

[0046] Specifically, the conditions for entering the second boiling stage refer to the conditions that must be met for the rice cooking equipment to exit the first boiling stage and enter the second boiling stage. The purpose of the first boiling stage is to rapidly evaporate the free water in the inner pot of the rice cooking equipment through heating and boiling, causing the starch granules of the rice to break down and become sticky. Generally, for rice with good water absorption, there is virtually no free water in the inner pot at the end of the first boiling stage. The first temperature detected by the bottom temperature sensor of the rice cooking equipment will rise rapidly, and the second temperature detected by the top temperature sensor will also change accordingly. Therefore, the entry conditions for the second boiling stage can be determined based on the relevant temperature parameters.

[0047] Furthermore, after the rice cooking equipment enters the second boiling stage, it needs to continue heating to maintain the temperature-related parameters inside the rice cooking equipment within the preset boiling temperature range, so as to increase the heat of the boiling stage and ensure that the rice core is thoroughly cooked.

[0048] The above-mentioned rice cooking method, by determining the temperature-related parameters inside the rice cooking equipment in real time during the first boiling stage and determining the time when the first boiling stage ends and the second boiling stage begins based on these temperature-related parameters, can ensure that by the end of the first boiling stage, the rice in the rice cooking equipment has fully absorbed water and there is basically no free water at the bottom, thus avoiding problems such as poor rice texture or undercooked rice.

[0049] In one embodiment, such as Figure 2 As shown, before the rice cooking device enters the first boiling stage in step 102, the rice cooking method further includes steps 202 to 204.

[0050] Step 202: After the rice cooking equipment enters the rice soaking stage, control the rice cooking equipment to heat at the first preset heating power value, and determine the temperature-related parameters in real time.

[0051] It is understandable that, since the four rice cooking stages mentioned above are continuous and interconnected, a relatively suitable temperature needs to be provided during the soaking stage to allow the rice grains to absorb water. This prevents the water temperature from reaching the gelatinization temperature due to excessively rapid heating, which would cause the surface of the rice grains to gelatinize and the center of the grains to be unable to absorb water, resulting in undercooked rice. Therefore, at the beginning of the soaking stage, heating needs to be carried out at a first preset heating power value, and temperature-related parameters need to be determined in real time to prevent excessively rapid heating and excessively high water temperatures.

[0052] Step 204: When the power switching conditions are met according to the temperature-related parameters, control the rice cooking equipment to switch to heating with the second preset heating power value until the running time of the rice soaking stage reaches the preset soaking time, and then enter the heating stage; wherein, the second preset heating power value is less than the first preset heating power value.

[0053] Specifically, the power switching condition refers to the conditions that must be met for the rice cooking equipment to switch from heating at a first preset heating power value to heating at a second preset heating power value. Since a relatively suitable temperature is required during the soaking stage, the power switching condition can be determined based on temperature-related parameters. It can be understood that at this point, the heating process of the rice cooking equipment has just begun, and the second temperature detected by the top temperature sensor of the rice cooking equipment may not have changed significantly. Therefore, the first temperature detected by the bottom temperature sensor of the rice cooking equipment can be used as a temperature-related parameter to determine whether the power switching condition is met.

[0054] Furthermore, when the first temperature exceeds the soaking temperature threshold, the power switching condition is met. The rice cooking equipment is then switched to heating at the second preset heating power value, and the first temperature is maintained within the preset soaking temperature range until the soaking stage reaches the preset soaking time, after which the heating stage begins. To maintain the required temperature during the soaking stage, the preset soaking temperature range must be greater than the soaking temperature threshold; that is, the lower limit of the preset soaking temperature range can be set as the soaking temperature threshold. Additionally, since residual heat can also raise the first temperature after heating stops, maintaining the first temperature within the preset soaking temperature range can be achieved by intermittently controlling the rice cooking equipment to heat at the second preset heating power value.

[0055] It is understood that the first preset heating power value is used to quickly raise the first temperature to the soaking temperature threshold required for the rice soaking stage, while the second preset heating power only needs to maintain the temperature. Therefore, the second preset heating power can be set to a power value lower than the first preset heating power value. Furthermore, both the first and second preset heating power values ​​are power values ​​of the heating unit.

[0056] In one embodiment, such as Figure 2 As shown, after the rice cooking device enters the heating stage in step 204, the rice cooking method further includes steps 206 and 208.

[0057] Step 206: Control the rice cooking equipment to heat at the first preset heating power value and determine the temperature-related parameters in real time.

[0058] Specifically, during the heating phase, the rice cooking equipment is controlled to heat again at the first preset heating power value to promote the uniform transfer of heat between the components inside the rice grains, ensuring that the rice grains are uniformly gelatinized from the outside to the inside. At the same time, it is still necessary to determine the relevant temperature parameters in real time so as to determine whether to end the heating phase and enter the first boiling phase based on the relevant temperature parameters within the rice cooking equipment.

[0059] Step 208: When the conditions for entering the first boiling stage are met based on the relevant temperature parameters, the first boiling stage is entered.

[0060] Specifically, the conditions for entering the first boiling stage represent the conditions that must be met for the rice cooking equipment to enter the first boiling stage after the heating stage. It can be understood that at this point, the rice cooking equipment has been fully heated to the point where free water boils, and both the first and second temperatures have changed significantly. Therefore, both the first and second temperatures can be used as temperature-related parameters to determine whether the conditions for entering the first boiling stage are met.

[0061] Furthermore, when the first temperature is greater than or equal to the first heating temperature threshold and the second temperature is greater than or equal to the second heating temperature threshold, it is determined that the conditions for entering the first boiling stage are met, and the rice cooking equipment enters the first boiling stage. It can be understood that the first heating temperature threshold is greater than the upper limit of the preset rice soaking temperature range.

[0062] In one embodiment, step 102, which involves determining the temperature-related parameters within the rice cooking device in real time after it enters the first boiling stage, includes: controlling the rice cooking device to heat at a third preset heating power value and determining the temperature-related parameters in real time after it enters the first boiling stage. The third preset heating power value is less than the first preset heating power value and greater than the second preset heating power value. Specifically, during heating at the third preset heating power value, the temperature-related parameters are determined in real time to determine whether the first boiling stage should end and the second boiling stage should begin based on the temperature-related parameters within the rice cooking device.

[0063] In one embodiment, such as Figure 3 As shown, step 104, when the conditions for entering the second boiling stage are met according to the temperature-related parameters, enters the second boiling stage and controls the temperature-related parameters in the rice cooking equipment to be maintained within the preset boiling temperature range, includes the following steps 302 to 306.

[0064] Step 302: When the running time of the first boiling stage is within the first preset boiling time, determine whether the conditions for entering the second boiling stage are met based on the temperature-related parameters.

[0065] Whether the rice cooking equipment has finished the first boiling stage and entered the second boiling stage can be determined by the running time, by temperature-related parameters, or by any one of these conditions being met.

[0066] Specifically, the first preset boiling time is the heating time preset in the standard cooking parameters corresponding to the first boiling stage, using the third preset heating power value. When the running time of the first boiling stage is within the first preset boiling time, the temperature-related parameters can be determined in real time, and it can be determined whether the conditions for entering the second boiling stage are met based on the temperature-related parameters, that is, whether the first boiling stage needs to be ended early and the second boiling stage needs to be entered.

[0067] Step 304: If yes, proceed to the second boiling stage and control the temperature-related parameters within the rice cooking equipment to maintain within the preset boiling temperature range.

[0068] Specifically, when the running time of the first boiling stage is within the first preset boiling time, and the conditions for entering the second boiling stage have been met according to the temperature-related parameters, the second boiling stage can be directly entered and the temperature-related parameters in the rice cooking equipment can be controlled to maintain within the preset boiling temperature range.

[0069] Step 306: If not, delay the first preset boiling time, and return to the step of determining whether the entry conditions for the second boiling stage are met based on temperature-related parameters when the running time of the first boiling stage is within the first preset boiling time, until the number of delays for the first preset boiling time reaches the preset number.

[0070] Specifically, when the running time of entering the first boiling stage has reached the first preset boiling time, and it is determined according to the temperature-related parameters that the conditions for entering the second boiling stage are still not met, the first preset boiling time can be delayed, and the process can return to step 302 to continue to determine whether the conditions for entering the second boiling stage are met.

[0071] The delay duration and number of delays for the first preset boiling time are not unique and can be set according to actual needs. It can be understood that delaying the first preset boiling time means updating the first preset boiling time with the delay duration and the number of delays, and replacing the original first preset boiling time with the updated first preset boiling time to return to step 302 for judgment.

[0072] Furthermore, when the number of delays applied to the first preset boiling time reaches a preset number (set to 1 in this application), or when the total running time of the first preset boiling time reaches the upper limit of the boiling time, and the conditions for entering the second boiling stage are still not met based on temperature-related parameters, the second boiling stage can be directly entered. The upper limit of the boiling time can be calculated based on the delay duration and the number of delays. This upper limit ensures that the rice has a sufficiently long boiling time, and that entering the second boiling stage directly after the delay also prevents the overall cooking time from becoming excessively long.

[0073] In one embodiment, the temperature-related parameters include a first temperature of the bottom temperature detection device of the rice cooking device and a second temperature of the top temperature detection device of the rice cooking device. The step 104 of determining whether the conditions for entering the second boiling stage are met based on the temperature-related parameters includes: when the first temperature is greater than or equal to a first preset temperature threshold and the second temperature is greater than or equal to a second preset temperature threshold, it is determined that the conditions for entering the second boiling stage are met.

[0074] It is understood that the rice cooking equipment provided in this application may have temperature detection devices configured at both the top and bottom. The temperature-related parameters within the rice cooking equipment may be either the temperature value detected by the top temperature detection device or the temperature value detected by the bottom temperature detection device.

[0075] The first temperature refers to the temperature value detected in real time by the bottom temperature detection device of the rice cooking equipment. The temperature detected by the bottom temperature detection device is related to the free water content in the rice cooking equipment during boiling. When the free water in the rice cooking equipment has basically evaporated, the temperature detected by the bottom temperature detection device will rise rapidly. Therefore, the first preset temperature threshold is the temperature value detected by the bottom temperature detection device when the free water in the rice cooking equipment has basically evaporated during the first boiling stage.

[0076] The second temperature refers to the real-time temperature value detected by the top temperature detection device of the rice cooking equipment. The temperature detected by the top temperature detection device represents the ambient temperature inside the rice cooking equipment and also changes during the boiling process due to variations in the free water content. Therefore, in addition to using the bottom temperature detection device to determine whether the conditions for entering the second boiling stage are met, the temperature detected by the top temperature detection device can be added for simultaneous judgment, making the determination of the timing of entering the second boiling stage more accurate. The second preset temperature threshold is the temperature value detected by the top temperature detection device when the free water in the first boiling stage of the rice cooking equipment has been basically evaporated.

[0077] Specifically, when the first temperature is greater than or equal to the first preset temperature threshold and the second temperature is greater than or equal to the second preset temperature threshold, it is determined that the conditions for entering the second boiling stage are met, and the rice cooking equipment is controlled to enter the second boiling stage; when the first temperature is less than the first preset temperature threshold or the second temperature is less than the second preset temperature threshold, it is determined that the conditions for entering the second boiling stage are not met, and the rice cooking equipment is controlled to remain in the first boiling stage.

[0078] In another embodiment, step 104, determining whether the entry condition for the second boiling stage is met based on temperature-related parameters, includes: determining that the entry condition for the second boiling stage is met when the first temperature is greater than or equal to a first preset temperature threshold. That is, the first temperature detected by the bottom temperature detection device can be used alone as the determination condition for the entry condition of the second boiling stage. Specifically, when the first temperature is greater than or equal to the first preset temperature threshold, it is determined that the entry condition for the second boiling stage is met, and the rice cooking equipment is controlled to enter the second boiling stage; when the first temperature is less than the first preset temperature threshold, it is determined that the entry condition for the second boiling stage is not met, and the rice cooking equipment is controlled to remain in the first boiling stage.

[0079] In one embodiment, such as Figure 4 As shown, step 104, which involves entering the second boiling stage and controlling the temperature-related parameters within the rice cooking device to remain within the preset boiling temperature range, includes steps 402 to 404.

[0080] Step 402: After the rice cooking equipment enters the second boiling stage, control the rice cooking equipment to heat at the fourth preset heating power value so that the first temperature is maintained within the preset boiling temperature range.

[0081] Specifically, the fourth preset heating power value is less than the first preset heating power value, and the fourth preset heating power value is greater than the third preset heating power value, so as to maintain the first temperature within the preset boiling temperature range, thereby increasing the heat and peak temperature during the boiling stage to ensure that the rice core is fully cooked.

[0082] Step 404: When the first temperature is maintained within the preset boiling temperature range for a period of time that reaches the second preset boiling time, the rice cooking stage begins.

[0083] In one embodiment, after the rice cooking device enters the steaming stage, the rice cooking method further includes: controlling the rice cooking device to heat at a fifth preset heating power value to maintain the first temperature within a preset steaming temperature range. The fifth preset heating power value is greater than a second preset heating power value and less than a third preset heating power value. It can be understood that during the steaming stage, after the first temperature is maintained within the preset steaming temperature range for a preset steaming time, the entire rice cooking process ends, and cooking is complete. The preset steaming time can be set to be the same as the second preset boiling time.

[0084] In one embodiment, to Figure 5 Flowcharts and Figure 6 Using a temperature change graph as an example, the principle of rice cooking methods will be explained.

[0085] Specifically, the rice cooking method mentioned in this application can be divided into five stages: soaking rice, heating, boiling stage 1, boiling stage 2, and simmering rice. When the user selects the rice cooking function, the cooking control method is as follows:

[0086] 1. Rice soaking stage OA: The rice cooker heats the rice to the first temperature TB (bottom temperature sensor) ≥ TB1 (rice soaking temperature threshold) at P1 power (first preset heating power value), then switches to P2 power heating (second preset heating power) and maintains the bottom temperature between [TB1 TB2] (preset rice soaking temperature range) for a period of time until t ≥ t1 (preset rice soaking time), and then enters the heating stage;

[0087] 2. Heating stage AB: Heating with power P1 until the second temperature TT (top temperature sensor) ≥ TT1 (first heating temperature threshold) and the first temperature TB ≥ TB3 (second heating temperature threshold) enters boiling stage 1, where P2 < P1, TB1 < TB2 < TB3.

[0088] 3. Boiling stage 1BC: Heat for t2 (first preset boiling time) with power P3 (third preset heating power value). If the second temperature TT ≥ TT2 (second preset temperature threshold) and the first temperature TB ≥ TB4 (first preset temperature threshold) within t2, then directly enter boiling stage 2. Otherwise, extend t2 to t3. After t3 (delay time) ends, enter boiling stage 2, where t2 < t3.

[0089] 4. Boiling stage 2CD: The power P4 (fourth preset heating power value) is maintained in the temperature range [TB5 TB6] (preset boiling temperature range) for a time of t4 (second preset boiling time). After the time is over, the rice simmering stage begins.

[0090] 5. Cooking stage DE: The cooking stage ends after maintaining power P5 (the fifth preset heating power value) for t4 time within the [TB7 TB8] (preset cooking temperature range).

[0091] In this order, TB1 < TB2 < TB3 < TB4 < TB5 < TB6, TB7 < TB8 < TB6, P2 < P5 < P3 < P4 < P1, t3 > t2 > t1 > t4. Specifically, the values ​​of t1, t2, t3, and t4 can range from 5 to 30 minutes; the values ​​of TB1, TB2, and TB3 can range from 30℃ to 60℃; the value of TB4 can range from 70℃ to 90℃; the values ​​of TB5 and TB6 can range from 90℃ to 110℃; and the values ​​of TB7 and TB8 can range from 85℃ to 105℃. The power values ​​of P1 to P5 can be determined according to the rated power of the specific model of the rice cooking equipment.

[0092] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0093] Based on the same inventive concept, this application also provides a rice cooking apparatus for implementing the rice cooking method described above. The solution provided by this apparatus is similar to the solution described in the above method; therefore, the specific limitations in one or more rice cooking apparatus embodiments provided below can be found in the limitations of the rice cooking method described above, and will not be repeated here.

[0101] In one embodiment, the temperature-related parameters include a first temperature detected by the bottom temperature detection device of the rice cooking equipment and a second temperature detected by the top temperature detection device of the rice cooking equipment.
