[0063] 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.

[0064] This embodiment provides a method for controlling a cooking appliance, and this embodiment uses the application of this method to a cooking appliance as an example for illustration. In one embodiment, a structural schematic diagram of the cooking appliance is shown below. Figure 1 As shown, Figure 1 In this design, 10 represents the pot body, 20 represents a bottom heating element located at the bottom of the pot body, 30 represents a side wall heating element located on the side wall of the pot body, 40 represents a bottom temperature sensor located at the corner of the bottom of the pot body, and 50 represents a top temperature sensor located on the top cover of the cooking appliance. Specifically, the bottom heating element and the side wall heating element can be heating coils, and no specific limitation is made. Those skilled in the art will understand that... Figure 1 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation. Specific cooking appliances may include more or fewer parts than those shown in the figure, or combine certain parts, or have different part arrangements.

[0065] Figure 2 This is a flowchart illustrating the control method for a cooking appliance provided in an embodiment of this application. The method is applied to the cooking appliance. In one embodiment, such as... Figure 2 As shown, it includes the following steps:

[0066] S201, according to the first heating control method, control the bottom heating component and the side wall heating component to work until the bottom temperature of the pot reaches the first preset temperature range and is maintained for the first preset duration.

[0067] The temperature at the bottom of the pot is measured by a temperature measuring device located at the bottom of the pot. This device can be a temperature sensor or a temperature sensing bulb; the specific type is not limited. A first preset temperature range and a first preset duration can be set. For example, the first preset temperature range can be set to 43 to 55 degrees Celsius.

[0068] In some embodiments, the bottom temperature of the pot body is controlled by, for example, Figure 1 The 40 bottom temperature sensing pack shown is obtained.

[0069] It is worth noting that heating will stop if the temperature at the bottom of the pot exceeds the first preset temperature range.

[0070] S202, according to the second heating control method, control the bottom heating component and the side wall heating component to work until the top temperature of the pot body is not less than the first preset temperature.

[0071] The temperature at the top of the pot is measured by a temperature measuring device located at the top of the pot. This device can be a temperature sensor or a temperature sensing bulb; there is no specific limitation. A first preset temperature can be set. For example, the first preset temperature can be set to any temperature value not less than 80 degrees Celsius.

[0072] In some embodiments, the top temperature of the pot body is determined by, for example... Figure 1 The 50 top temperature sensing pack shown is obtained.

[0073] S203, according to the third heating control method, control the bottom heating component and the side wall heating component to work until the bottom temperature of the pot body reaches the second preset temperature, and the control time according to the third heating control method reaches the second preset time.

[0074] The second preset temperature is not less than the boiling point of water, which refers to the boiling point corresponding to the altitude of the cooking appliance's environment and the purity of the water. The second preset temperature and the second preset duration are adjustable. For example, the second preset duration can be set to any duration between 3 and 10 minutes.

[0075] S204, according to the fourth heating control method, control the bottom heating component and the side wall heating component to work so that the bottom temperature of the pot body is maintained within the second preset temperature range until the control time of the fourth heating control method reaches the third preset time.

[0076] The second preset temperature range and the third preset duration can be set. For example, the second preset temperature range can be set to no less than 100 degrees Celsius.

[0077] S205, according to the fifth heating control method, control the bottom heating component and the side wall heating component to work so that the bottom temperature of the pot body is maintained within the third preset temperature range until the control time of the fifth heating control method reaches the fourth preset time.

[0078] The third preset temperature range can be the same as the second preset temperature range. Specifically, the third preset temperature range and the fourth preset duration can be set. For example, the fourth preset duration can be set to any duration between 5 and 10 minutes. The typically set fourth preset duration ensures that the quality of the food cooked by the cooking appliance meets the relevant national standards.

[0079] This embodiment provides a control method for a cooking appliance, which includes a pot body, a bottom heating element located at the bottom of the pot body, and a side wall heating element located on the side wall of the pot body. The bottom heating element and the side wall heating element are controlled sequentially according to a first heating control mode, a second heating control mode, a third heating control mode, a fourth heating control mode, and a fifth heating control mode until their respective termination conditions are met. Compared to the problem of uneven heating within the cooking appliance in traditional technologies, this embodiment ensures uniform heating within the cooking appliance by setting a side wall heating element on the side wall of the pot body and controlling the bottom heating element and the side wall heating element sequentially according to different heating control modes.

[0080] In one embodiment, according to the first heating control method, the bottom heating component and the side wall heating component are controlled to operate until the bottom temperature of the pot reaches a first preset temperature range and is maintained for a first preset duration. Based on this, a flowchart of the first heating control method is provided, as follows. Figure 3 As shown, it includes the following:

[0081] S301, control the bottom heating component to heat according to the first bottom heating duration.

[0082] The heating duration of the first bottom is a positive integer in seconds.

[0083] S302, according to the first pause duration, pause heating through the bottom heating component.

[0084] The first pause duration is a positive integer in seconds.

[0085] S303, the side wall heating component is controlled to heat according to the first side wall heating time, and the difference between the first side wall heating time and the first bottom heating time is within a preset range.

[0086] The heating duration of the first sidewall is a positive integer in seconds. A preset range can be set.

[0087] In some embodiments, the difference between the heating time of the first sidewall and the heating time of the first bottom is within a preset range, including:

[0088] 0≤A3-A1≤3, where A3 is the heating time of the first sidewall and A1 is the heating time of the first bottom.

[0089] The heating time for the first side wall is longer than that for the first bottom because the heat transferred from the side wall heating component to the pot is lower than that transferred from the bottom heating component. Therefore, in order to ensure uniform heating, the difference between the heating time for the first side wall and the heating time for the first bottom is set within a preset range.

[0090] S304, according to the second pause duration, pause heating through the side wall heating assembly.

[0091] The second pause duration is a positive integer in seconds.

[0092] S305, if the bottom temperature of the pot body does not reach the first preset temperature range, or if it reaches the first preset temperature range but the duration of maintenance does not reach the first preset duration, return to the step of controlling the bottom heating component to heat according to the first bottom heating duration and continue to execute until the bottom temperature of the pot body reaches the first preset temperature range and the duration of maintenance reaches the first preset duration.

[0093] In this embodiment, the bottom heating component and the side wall heating component heat for similar durations, and the pause duration for pausing heating is increased during the switching between the bottom heating component and the side wall heating component, which can promote a uniform temperature distribution inside the pot during the heating process.

[0094] In one embodiment, according to the second heating control method, the bottom heating component and the side wall heating component are controlled to operate until the top temperature of the pot body is not lower than the first preset temperature. Based on this, a flowchart of the second heating control method is provided, as follows: Figure 4 As shown, it includes the following:

[0095] S401, control the bottom heating component to heat according to the second bottom heating duration.

[0096] The second bottom heating duration is a positive integer in seconds.

[0097] S402, according to the third pause duration, pause heating through the bottom heating component.

[0098] The third pause duration is a positive integer in seconds.

[0099] S403, control the side wall heating component to heat according to the second side wall heating time, and the difference between the second side wall heating time and the second bottom heating time is within a preset range.

[0100] The heating duration of the second sidewall is a positive integer in seconds.

[0101] In some embodiments, the difference between the heating time of the second sidewall and the heating time of the second bottom is within a preset range, including:

[0102] 0≤B3-B1≤3, where B3 is the heating time of the second sidewall and B1 is the heating time of the second bottom.

[0103] S404, pause the heating via the sidewall heating component according to the fourth pause duration; wherein, the sum of the second bottom heating duration and the second sidewall heating duration is not less than the sum of the third pause duration and the fourth pause duration, and the sum of the second bottom heating duration and the second sidewall heating duration is not less than the sum of the first sidewall heating duration and the first bottom heating duration.

[0104] Wherein, the fourth pause duration is a positive integer in seconds.

[0105] S405, in the case where the top temperature of the pot body is less than the first preset temperature, return to the step of controlling the bottom heating component to heat according to the second bottom heating duration and continue to execute until the top temperature of the pot body is not less than the first preset temperature.

[0106] In this embodiment, the bottom heating component and the sidewall heating component heat for a similar heating duration, which can make the temperature in the pot body rise evenly.

[0107] In one embodiment, according to the third heating control method, control the bottom heating component and the sidewall heating component to work until the bottom temperature of the pot body reaches the second preset temperature and the control duration according to the third heating control method reaches the second preset duration. Based on this, a flow schematic diagram of the third heating control method is provided, as Figure 5 shown, including the following:

[0108] S501, control the bottom heating component to heat according to the third bottom heating duration.

[0109] Wherein, the third bottom heating duration is a positive integer in seconds.

[0110] S502, pause the heating via the bottom heating component according to the fifth pause duration.

[0111] Wherein, the fifth pause duration is a positive integer in seconds.

[0112] S503, control the sidewall heating component to heat according to the third sidewall heating duration, the third bottom heating duration is greater than the third sidewall heating duration and not greater than a first preset multiple of the third sidewall heating duration.

[0113] Wherein, the third sidewall heating duration is a positive integer in seconds. The first preset multiple can be set.

[0114] In some embodiments, the third bottom heating duration is greater than the third sidewall heating duration and not greater than a first preset multiple of the third sidewall heating duration, including:

[0115] C3 < C1 ≤ 3C3, where C1 is the third bottom heating duration and C3 is the third sidewall heating duration.

[0116] The reason for setting the heating time of the third bottom to be no more than the first preset multiple of the heating time of the third side wall is that the moisture content of the food in the pot is unevenly distributed. This is to prevent the food at the bottom of the pot from having too high a moisture content due to the heating time of the third bottom being too long.

[0117] S504, according to the sixth pause duration, the heating through the side wall heating assembly is paused; wherein, the sum of the third bottom heating duration and the third side wall heating duration is not less than the sum of the first side wall heating duration and the first bottom heating duration, and is not greater than the sum of the second bottom heating duration and the second side wall heating duration.

[0118] The sixth pause duration is a positive integer in seconds.

[0119] Here, the sum of the heating time of the third bottom and the heating time of the third side wall is no greater than the sum of the heating time of the second bottom and the heating time of the second side wall. At this point, the water in the pot has boiled, so the heating time can be reduced to maintain boiling and reduce power loss.

[0120] S505, if the bottom temperature of the pot body has not reached the second preset temperature or the control time according to the third heating control method has not reached the second preset time, return to the step of controlling the bottom heating component to heat according to the third bottom heating time and continue to execute until the bottom temperature of the pot body reaches the second preset temperature and the control time according to the third heating control method reaches the second preset time.

[0121] In this embodiment, since the heat utilization rate of the bottom heating component is the highest, increasing the third bottom heating time can ensure that the food being cooked in the pot boils and gelatinizes fully.

[0122] In one embodiment, according to the fourth heating control method, the bottom heating component and the side wall heating component are controlled to operate, so that the bottom temperature of the pot body is maintained within a second preset temperature range until the control duration of the fourth heating control method reaches a third preset duration. Based on this, a flowchart of the fourth heating control method is provided, as follows. Figure 6 As shown, it includes the following:

[0123] S601, control the bottom heating component to heat according to the fourth bottom heating duration.

[0124] The fourth bottom heating duration is a positive integer in seconds.

[0125] S602, according to the seventh pause duration, pause heating through the bottom heating component.

[0126] The seventh pause duration is a positive integer in seconds.

[0127] S603. Control the sidewall heating component to heat according to the fourth sidewall heating duration. The fourth bottom heating duration is greater than the fourth sidewall heating duration and not greater than the second preset multiple of the fourth sidewall heating duration, and the second preset multiple is greater than the first preset multiple.

[0128] Among them, the fourth sidewall heating duration is a positive integer in seconds. The second preset multiple can be set.

[0129] In some embodiments, the fourth bottom heating duration is greater than the fourth sidewall heating duration and not greater than the second preset multiple of the fourth sidewall heating duration, including:

[0130] D3 < D1 ≤ 5D3, where D1 is the fourth bottom heating duration and D3 is the fourth sidewall heating duration.

[0131] Here, there is basically no freely flowing water in the pot body, and it is necessary to increase the fourth bottom heating duration to maintain the temperature of the food in the pot body through the water vapor and water bubbles generated during bottom heating.

[0132] S604. Pause heating through the sidewall heating component according to the eighth pause duration; among them, the sum of the seventh pause duration and the eighth pause duration is not less than the sum of the fifth pause duration and the sixth pause duration.

[0133] Among them, the eighth pause duration is a positive integer in seconds.

[0134] S605. In the case where the control duration according to the fourth heating control method does not reach the third preset duration, return to the step of controlling the bottom heating component to heat according to the fourth bottom heating duration and continue to execute until the control duration according to the fourth heating control method reaches the third preset duration.

[0135] In this embodiment, according to the fourth heating control method, control the bottom heating component and the sidewall heating component to work. At this time, there is no flowing water in the pot body, and the heat transfer only remains the solid heat transfer between the foods in the pot body, or the heat transfer between the water vapor and the foods in the pot body. However, the foods in the pot body are not completely cooked. Use the bottom heating component to heat mainly, increase the fourth bottom heating duration, and make the steam transfer heat from bottom to top, which is beneficial to maintaining the high temperature of the upper-layer foods in the pot body far from the heat source and further cooking them.

[0136] In one embodiment, according to the fifth heating control method, control the bottom heating component and the sidewall heating component to work so that the bottom temperature of the pot body is maintained within the third preset temperature range until the control duration according to the fifth heating control method reaches the fourth preset duration. Based on this, a flow chart of the fifth heating control method is provided, as Figure 7 shown, including the following content:

[0137] S701 controls the bottom heating component to heat according to the fifth bottom heating duration.

[0138] The fifth bottom heating duration is a positive integer in seconds.

[0139] S702, according to the ninth pause duration, pauses heating through the bottom heating component.

[0140] The ninth pause duration is a positive integer in seconds.

[0141] S703, according to the heating time of the fifth side wall, control the side wall heating component to heat, the heating time of the fifth bottom is not less than the heating time of the fifth side wall and not greater than the heating time of the fourth bottom, and the difference between the heating time of the fifth bottom and the heating time of the fifth side wall is within a preset range.

[0142] The heating duration of the fifth sidewall is a positive integer in seconds.

[0143] In some embodiments, the difference between the fifth bottom heating time and the fifth sidewall heating time is within a preset range, including:

[0144] 0≤E1-E3≤3, where E1 is the heating time of the fifth bottom and E3 is the heating time of the fifth side wall.

[0145] The fifth bottom heating time should not exceed the fourth bottom heating time because the food in the pot is basically cooked at this point and does not need to be heated continuously. If the fifth bottom heating time is too long, the food in the pot may burn.

[0146] S704, heating through the side wall heating assembly is paused according to the tenth pause duration; wherein the sum of the ninth and tenth pause durations is not less than the sum of the seventh and eighth pause durations.

[0147] The tenth pause duration is a positive integer in seconds.

[0148] S705, if the control duration according to the fifth heating control method has not reached the fourth preset duration, return to the step of controlling the bottom heating component to heat according to the fifth bottom heating duration and continue to execute until the control duration according to the fifth heating control method reaches the fourth preset duration.

[0149] In this embodiment, the heating time of the fifth side wall is kept close to that of the fifth bottom, so that the temperature of the upper food in the pot is close to that of the lower food in the pot, and the bottom temperature of the pot is kept within the third preset temperature range, which can further balance the moisture inside the food in the pot.

[0150] In addition, this application also provides a cooking utensil, such as Figure 1 The schematic diagram of the cooking appliance shown includes a memory, a processor, a pot body 10, a bottom heating element 20 located at the bottom of the pot body, and a side wall heating element 30 located on the side wall of the pot body. The memory stores a computer program, and the processor executes the computer program to implement the steps in the above-described method embodiments.

[0151] In one embodiment, a protrusion is provided at the bottom of the pot body.

[0152] Optionally, the protrusion is located at the center of the bottom of the pot body, the height of the protrusion is higher than the height of the pot body where the maximum amount of food can be held, and the bottom diameter of the protrusion does not exceed 1 / 2 of the overall diameter of the pot body.

[0153] In this embodiment, a protrusion is provided at the bottom of the pot body, which can increase the heating area inside the pot body and shorten the heat transfer distance inside the pot body.

[0154] In one embodiment, such as Figure 1 The sidewall heating assembly 30 shown includes at least one of a first heating assembly 31 located on the outer peripheral sidewall of the pot body or a second heating assembly 32 located on the inner sidewall of the protrusion.

[0155] When both the first heating component 31 and the second heating component 32 are present, the first heating component 31 and the second heating component 32 are connected in series, that is, the heating time of the first heating component 31 and the second heating component 32 is equal, and the height of the first heating component 31 and the second heating component 32 is consistent.

[0156] In this embodiment, the second heating component located on the inner wall of the protrusion can shorten the heat transfer distance, making the temperature distribution inside the pot more uniform during the heating process. Furthermore, the first heating component and the second heating component are connected in series and heated simultaneously at the same height, which can make the heating temperature distribution at the same height more uniform and improve the cooking quality of food in the cooking appliance.

[0157] Here, a specific embodiment of the control method for cooking appliances is described in detail.

[0158] Taking a rice cooker as an example, the cooking appliance includes a pot body, a bottom heating element located at the bottom of the pot body, a side wall heating element located on the side wall of the pot body, a bottom temperature sensor located at the corner of the bottom of the pot body, and a top temperature sensor located on the top cover of the cooking appliance. The side wall heating element includes a first heating element located on the outer peripheral side wall of the pot body and a second heating element located on the inner side wall of the protrusion, with the first and second heating elements connected in series; the bottom of the pot body of the cooking appliance is provided with a protrusion.

[0159] The process of cooking rice using this cooking appliance is divided into five stages: soaking the rice, heating up, the first boiling stage, the second boiling stage, and simmering. The implementation flow of the control method for this cooking appliance includes:

[0160] Soaking rice stage: According to the first heating control method, control the bottom heating component and the side wall heating component to work until the bottom temperature of the pot reaches the first preset temperature range and is maintained for the first preset time.

[0161] Specifically, the first heating control method involves controlling the bottom heating component and the side wall heating component to operate using a duty cycle of A1:A2:A3:A4. Here, A1 is the first bottom heating duration, A2 is the first pause duration, A3 is the first side wall heating duration, and A4 is the second pause duration. Furthermore, A1, A2, A3, and A4 are all positive integers, and 0 ≤ A3 - A1 ≤ 3.

[0162] Heating phase: According to the second heating control method, the bottom heating component and the side wall heating component are controlled to work until the temperature of the top of the pot is not less than the first preset temperature.

[0163] Specifically, the second heating control method uses a duty cycle of B1:B2:B3:B4 to control the operation of the bottom heating component and the side wall heating component. Here, B1 is the second bottom heating duration, B2 is the third pause duration, B3 is the second side wall heating duration, and B4 is the fourth pause duration. B1, B2, B3, and B4 are all positive integers, and 0 ≤ B3 - B1 ≤ 3, B2 + B4 ≤ B1 + B3, and A1 + A3 ≤ B1 + B3. It should be understood that the purpose of the heating phase is to quickly bring the rice and water to a boiling state, so it exits based on the rice and water temperature. The top temperature sensor can reflect the rice and water temperature well, while the correlation between the bottom temperature sensor and the rice and water temperature is much worse than that of the top temperature sensor. Therefore, here, only the top temperature sensor is used to monitor the temperature of the top of the pot to ensure it is not lower than the first preset temperature. During the heating phase, the bottom temperature monitored by the bottom temperature sensor is generally only used as a protective temperature to prevent dry burning due to insufficient water in the pot.

[0164] First boiling stage: According to the third heating control method, the bottom heating component and the side wall heating component are controlled to work until the bottom temperature of the pot reaches the second preset temperature, and the control time according to the third heating control method reaches the second preset time.

[0165] Specifically, the third heating control method is to control the bottom heating component and the side wall heating component to work with a duty cycle of C1:C2:C3:C4. Among them, C1 is the third bottom heating duration, C2 is the fifth pause duration, C3 is the third side wall heating duration, and C4 is the sixth pause duration. And C1, C2, C3, and C4 are all positive integers, and C3 < C1 ≤ 3C3, A1 + A3 ≤ C1 + C3 ≤ B1 + B3. It should be understood that the water in the pot also boils during the first boiling stage. Monitoring the bottom temperature of the pot through the bottom temperature sensor is to prevent dry burning at the bottom and cause the bottom rice to turn yellowish-brown.

[0166] Second boiling stage: According to the fourth heating control method, control the bottom heating component and the side wall heating component to work so that the bottom temperature of the pot is maintained within the second preset temperature range until the control duration according to the fourth heating control method reaches the third preset duration.

[0167] Specifically, the fourth heating control method is to control the bottom heating component and the side wall heating component to work with a duty cycle of D1:D2:D3:D4. Among them, D1 is the fourth bottom heating duration, D2 is the seventh pause duration, D3 is the fourth side wall heating duration, and D4 is the eighth pause duration. And D1, D2, D3, and D4 are all positive integers, and D3 < D1 ≤ 5D3, C2 + C4 ≤ D2 + D4. It should be understood that the rice has reached at least 100 degrees Celsius during the second boiling stage. Monitoring the bottom temperature of the pot through the bottom temperature sensor is to prevent dry burning at the bottom and cause the bottom rice to turn yellowish-brown.

[0168] Steaming stage: According to the fifth heating control method, control the bottom heating component and the side wall heating component to work so that the bottom temperature of the pot is maintained within the third preset temperature range until the control duration according to the fifth heating control method reaches the fourth preset duration.

[0169] Specifically, the fifth heating control method is to control the bottom heating component and the side wall heating component to work with a duty cycle of E1:E2:E3:E4. Among them, E1 is the fifth bottom heating duration, E2 is the ninth pause duration, E3 is the fifth side wall heating duration, and E4 is the tenth pause duration. And E1, E2, E3, and E4 are all positive integers, and E3 ≤ E1 ≤ D1, 0 ≤ E1 - E3 ≤ 3, D2 + D4 ≤ E2 + E4. It should be understood that the temperature change of the top temperature sensor is not significant during the steaming stage, the rice is basically cooked, and it is mainly necessary to maintain the rice temperature to further evenly disperse the moisture in the rice grains, improve the quality of the rice, and monitor the bottom temperature of the pot through the bottom temperature sensor to prevent dry burning at the bottom and cause the bottom rice to turn yellowish-brown.

[0170] The cooking appliance control method provided in this embodiment optimizes the shape of the pot and the heating mode of the heating components, increases the heating area, and shortens the heat transfer distance, resulting in a more uniform temperature distribution within the pot. This improves the heating speed and enhances the quality of cooked rice. Furthermore, the pause time in the first boiling stage is shorter than that in the second boiling stage, enabling rapid boiling in the first stage and maintaining boiling in the second stage. By employing different heating control methods, the method avoids the problems of slow temperature rise due to short heating time or food charring at the bottom of the pot due to long heating time, which can occur when using the same heating control method.

[0171] 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.
