Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking equipment, in particular to a control method and device of cooking equipment, a readable storage medium and cooking equipment. BACKGROUND

[0002] In the related art, the cooking equipment controls the cooking stage based on temperature, such as by setting a temperature sensor, collecting the local temperature of the inner pot, and adjusting the heating power of the heating element. However, due to the large area of the bottom of the inner pot, the temperature detection error of this control method is large, resulting in poor cooking effect. SUMMARY

[0003] The present application aims to at least solve one of the technical problems existing in the prior art or related art.

[0004] To this end, the first aspect of the present application provides a control method of cooking equipment.

[0005] The second aspect of the present application provides a control device of cooking equipment.

[0006] The third aspect of the present application provides a control device of cooking equipment.

[0007] The fourth aspect of the present application provides a readable storage medium.

[0008] The fifth aspect of the present application provides cooking equipment.

[0009] Therefore, the first aspect of the present application provides a control method of cooking equipment, the cooking equipment comprising an inner pot, a first heating element and a second heating element, wherein the first heating element is arranged opposite to a first region of the inner pot, the second heating element is arranged opposite to a second region of the inner pot, and the heating power of the first heating element is greater than that of the second heating element; the control method comprising: in response to a cooking start signal, controlling the first heating element and the second heating element to continuously heat based on a target heating power; acquiring a first temperature of the first region and a second temperature of the second region; and adjusting the working parameters of the first heating element and / or the second heating element based on the first temperature and the second temperature.

[0010] In this technical solution, the cooking equipment includes but is not limited to an electric rice cooker, an electric stew pot, an electric pressure cooker, an electric fryer, etc. The cooking equipment includes an inner pot arranged in the body of the cooking equipment for holding food materials to be cooked. On the outside of the inner pot, a first heating element and a second heating element are arranged towards the outer wall of the inner pot. Exemplarily, the first heating element is located on the side of the bottom wall of the inner pot, and the second heating element is located at the center of the bottom wall of the inner pot, so that the first heating element is arranged around the second heating element. Exemplarily, the first heating element is arranged towards the bottom wall of the inner pot, and the second heating element is arranged around the side wall of the inner pot.

[0011] In this design, the first heating element is defined as the outer ring heating element, and the second heating element is defined as the inner ring heating element. The first heating element can cover a larger area of ​​the bottom wall of the inner pot, and the area covered by the first heating element is called the first region. The second heating element can cover the center of the bottom wall of the inner pot, and the area covered by the second heating element is called the second region. It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element is greater than the heating power of the second heating element, enabling the dual heating elements to heat the cooking device more evenly.

[0012] Since the cooking device of this application is designed with dual heating elements, in order to improve the temperature control accuracy, the cooking device of this application is also equipped with dual temperature sensors. For example, the temperature sensors can be NTC (Negative Temperature Coefficient thermistor).

[0013] When the cooking device is performing a cooking operation, the user puts the ingredients to be cooked and water and other auxiliary materials into the inner pot, and sets the cooking mode. The main control chip of the cooking device determines parameters such as the target cooking temperature and target cooking time based on the cooking mode, and generates a cooking start signal when the user inputs to start cooking or when the user's reserved cooking time arrives.

[0014] After detecting a cooking start signal, the main control chip of the cooking device controls the first and second heating elements to begin heating. In the initial cooking stage, the purpose of the first and second heating elements is to rapidly heat the inner pot; both heating elements continuously heat during this period. This stage is referred to as the rapid heating stage. For example, the first and second heating elements continuously heat based on a target heating power. The heating power of the first and second heating elements based on the target heating power can be the same or different. For example, the first heating element continuously heats based on a first target heating power, and the second heating element continuously heats based on a second target heating power.

[0015] During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperatures of the first and second regions, obtaining a first temperature and a second temperature. Since the first heating element is oriented towards the first region and the second heating element is oriented towards the second region, the first temperature better reflects the heating effect of the first heating element, and the second temperature better reflects the heating effect of the second heating element.

[0016] Based on the first temperature and the second temperature, the cooking equipment is controlled to perform cooking operations. Specifically, the operating parameters of at least one of the first heating element and the second heating element are used to achieve dual-zone temperature control, thereby enabling more precise temperature control of the cooking process and improving the cooking effect of the cooking equipment.

[0017] In addition, the control method for the cooking equipment in the above-mentioned technical solution provided in this application may also have the following additional technical features:

[0018] In some technical solutions of this application, optionally, the operating parameters include heating time. Based on a first temperature and a second temperature, adjusting the operating parameters of the first heating element and / or the second heating element includes: adjusting the heating time of the first heating element and the second heating element when either the first temperature or the second temperature is greater than a temperature threshold; wherein the temperature threshold is associated with the target cooking temperature corresponding to the cooking start signal.

[0019] In this technical solution, the operating parameters of the first heating element and the second heating element include heating duration. For example, the heating duration can be the total heating duration of the heating element in one heating cycle, or it can be the heating duration and the interval duration when the heating element is performing intermittent heating.

[0020] During the cooking process, the cooking equipment continuously monitors the temperatures of the first and second zones, as mentioned above. When either the first temperature or the second temperature exceeds a certain threshold, it indicates that the pot temperature has reached a certain level. At this point, the cooking equipment transitions from a rapid heating phase to an intermittent heating phase. In this phase, the heating duration of the first and second heating elements is adjusted to ensure intermittent heating. This avoids heat buildup caused by continuous heating and overheating due to temperature sensor lag, ensuring that the actual cooking temperature always matches the target cooking temperature.

[0021] The temperature threshold mentioned above is determined based on the target cooking temperature. For example, the temperature threshold can be calculated based on the target cooking temperature and a preset offset temperature value.

[0022] The technical solution of this application prevents the cooking temperature of the cooking equipment from exceeding the target cooking temperature by switching from a rapid heating stage to an intermittent heating stage when the temperature conditions are met, thereby improving the cooking effect of the cooking equipment.

[0023] In some technical solutions of this application, optionally, the temperature threshold includes a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is determined based on the target cooking temperature and a first preset temperature value, and the second temperature threshold is determined based on the target cooking temperature and the second preset temperature value; when either the first temperature or the second temperature is greater than the temperature threshold, adjusting the heating time of the first heating element and the second heating element includes:

[0024] When the first temperature is greater than the first temperature threshold, or when the second temperature is greater than the second threshold temperature, the heating time of the first heating element and the second heating element is adjusted; wherein, the range of the first preset temperature value is greater than or equal to 8℃ and less than or equal to 15℃; the range of the second preset temperature value is greater than or equal to 8℃ and less than or equal to 15℃.

[0025] In this technical solution, the temperature threshold specifically includes a first temperature threshold corresponding to the first region and a second temperature threshold corresponding to the second region. When determining whether the temperature threshold is exceeded, the first temperature is compared with the first temperature threshold, and the second temperature is compared with the second temperature threshold. When either the first temperature is greater than the first temperature threshold or the second temperature is greater than the second temperature threshold, the conditions for switching from the rapid heating stage to the intermittent heating stage are met.

[0026] The first temperature threshold is determined based on the sum of the target cooking temperature and the first preset temperature. Assuming the target cooking temperature for this cooking operation is T, and the first preset temperature is d1, then the first temperature threshold T1 = T - d1. Similarly, assuming the second preset temperature is d2, then the second temperature threshold T2 = T - d2.

[0027] For example, 8℃≤d1≤15℃. For example, 8℃≤d2≤15℃.

[0028] For example, d1 = 10°C. For example, d2 = 10°C.

[0029] The technical solution of this application can achieve precise control of cooking temperature by setting temperature thresholds for different regions.

[0030] In some technical solutions of this application, adjusting the heating duration of the first heating element and the second heating element includes: controlling the first heating element to heat for a first duration in each first heating cycle, and controlling the second heating element to heat for a second duration in each second heating cycle; wherein, the cycle length of the first heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; the value range of the first duration is greater than or equal to 4 seconds and less than or equal to 8 seconds; the cycle length of the second heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; the value range of the second duration is greater than or equal to 4 seconds and less than or equal to 8 seconds.

[0031] In this technical solution, when controlling the first heating element and the second heating element to heat alternately, the interval heating is achieved by adjusting the heating duration of the first heating element and the second heating element in each heating cycle.

[0032] For example, the first heating element heats based on a first heating cycle, wherein in each first heating cycle, the first heating element continuously heats for a first duration and then stops heating until the next first heating cycle begins, and then continues heating for a first duration, and so on.

[0033] Similarly, the second heating element heats based on the second heating cycle. In each second heating cycle, the second heating element continuously heats for a second duration and then stops heating until the next second heating cycle begins, after which it continues heating for a second duration.

[0034] For example, the cycle length of the first heating cycle is 10 to 30 seconds. Taking a cycle length of 10 seconds and a duration of 5 seconds as an example, in each first heating cycle, the first heating element is heated for 5 seconds and then stopped for 5 seconds until it enters the next first cycle of 10 seconds, where it is heated for another 5 seconds and then stopped for 5 seconds.

[0035] For example, the cycle length of the second heating cycle is 10 to 30 seconds. Taking a cycle length of 15 seconds and a duration of 8 seconds as an example, in each second heating cycle, the second heating element heats for 8 seconds and then stops heating for 7 seconds until it enters the next second cycle of 15 seconds, where it heats for another 8 seconds and then stops heating for 7 seconds.

[0036] The technical solution of this application achieves an intermittent heating mode by controlling the heating duration of the first heating element and the second heating element in each heating cycle, thereby avoiding problems such as overheating and scorching, and realizing precise control of heating.

[0037] In some technical solutions of this application, optionally, the operating parameters also include heating power; after adjusting the heating time of the first heating element and the second heating element, the control method further includes: when the first temperature is greater than the third temperature threshold and the second temperature is greater than the fourth temperature threshold, controlling the second heating element to stop heating, and controlling the first heating element to adjust the heating power so that the first temperature and the second temperature match the target cooking temperature; wherein, the third temperature threshold is determined based on the target cooking temperature and the third preset temperature value, the fourth temperature threshold is determined based on the target cooking temperature and the fourth preset temperature value, the value range of the third preset temperature value is greater than or equal to 3℃ and less than or equal to 8℃; the value range of the fourth preset temperature value is greater than or equal to 0.5℃ and less than or equal to 3℃.

[0038] In this technical solution, the first heating element is an outer ring heating element, and the second heating element is an inner pot heating element. The outer ring heating element can heat a larger area of ​​the bottom of the inner pot, and the second heating element can heat the center of the bottom of the inner pot.

[0039] When the first temperature value of the first zone is greater than the third temperature threshold, and at the same time the second temperature value of the second zone is greater than the fourth temperature threshold, it means that the temperature of the inner pot and the food has reached the target cooking temperature. At this time, the second heating element of the inner ring is controlled to stop heating, and the heating power of the first heating element of the outer ring is adjusted so that the temperature of the inner pot and the food is maintained at the set target cooking temperature, thereby ensuring that the cooking effect matches the target cooking temperature set by the cooking program.

[0040] For example, let the target cooking temperature be T, the third temperature threshold be T3, and the third preset temperature be d3, then T3 = T - d3. Similarly, let the fourth temperature threshold be T4 and the fourth preset temperature be d4, then T4 = T - d4.

[0041] For example, 3℃≤d3≤8℃. For example, 0.5℃≤d4≤3℃.

[0042] For example, d3 = 5℃. For example, d4 = 1℃.

[0043] The technical solution of this application controls the inner ring heating element to stop heating when both the first and second zones of the inner pot reach near the target set temperature, and at the same time adjusts the heating power of the outer ring heating element, so as to maintain the temperature of the inner pot and the food at the target cooking temperature and ensure that the cooking effect meets expectations.

[0044] Optionally, in some technical solutions of this application, after adjusting the heating time of the first heating element and the second heating element, the control method further includes: when the first temperature is less than a fifth temperature threshold and the second temperature is less than a sixth temperature threshold, controlling the first heating element and the second heating element to continuously heat based on the target heating power; wherein, the fifth temperature threshold is determined according to the target cooking temperature and a fifth preset temperature value, the sixth temperature threshold is determined according to the target cooking temperature and a sixth preset temperature value, the fifth preset temperature value is greater than or equal to 5℃ and less than or equal to 10℃; the sixth preset temperature value is greater than or equal to 1℃ and less than or equal to 5℃.

[0045] In this technical solution, after the cooking equipment leaves the rapid heating stage and enters the intermittent heating stage, if the temperature of the first area is less than the fifth temperature threshold and the temperature of the second area is less than the sixth temperature threshold, it indicates that the temperature of the inner pot and the food has dropped. At this time, the first heating element and the second heating element are controlled again to continue heating according to the rapid heating stage, based on the target heating power, so that the temperature of the inner pot and the food can quickly return to the target cooking temperature.

[0046] For example, let the target cooking temperature be T, the fifth temperature threshold be T5, and the fifth preset temperature be d5, then T5 = T - d5. Similarly, let the sixth temperature threshold be T6 and the sixth preset temperature be d6, then T6 = T - d6.

[0047] For example, 5℃≤d5≤10℃. For example, 1℃≤d6≤5℃.

[0048] For example, d5 = 7°C. For example, d6 = 2°C.

[0049] The technical solution of this application controls the cooking equipment to return to the rapid heating stage after the temperature of the first and second zones of the inner pot decreases, thereby preventing the temperature of the inner pot and the food from decreasing and ensuring the cooking effect.

[0050] Optionally, in some technical solutions of this application, controlling the first heating element and the second heating element to continuously heat based on a target heating power includes: controlling the first heating element to continuously heat at a first heating power, and controlling the second heating element to continuously heat at a second heating power; wherein, the first heating power is the maximum heating power of the first heating element, and the second heating power is the maximum heating power of the second heating element.

[0051] In this technical solution, during the rapid heating phase, the first heating element can be controlled to continuously heat based on the first heating power, while the second heating element can be controlled to continuously heat based on the second heating power.

[0052] For example, the first heating power is the maximum heating power of the first heating element, and the second heating power is the maximum heating power of the second heating element.

[0053] For example, if the first heating element has specifications of 220V, 50Hz, and 1000W, then the first heating power is 1000W. If the second heating element has specifications of 220V, 50Hz, and 500W, then the second heating power is 500W.

[0054] The technical solution of this application controls both heating elements to continuously heat at their maximum power during the rapid heating phase, which can quickly increase the temperature of the inner pot and the food, thereby improving cooking efficiency.

[0055] In some technical solutions of this application, optionally, when the first temperature is greater than the seventh temperature threshold or the second temperature is greater than the eighth temperature threshold, the first heating element and the second heating element are both controlled to stop heating until the first temperature and the second temperature are both less than the ninth temperature threshold, and then the first heating element and the second heating element are controlled to resume heating; wherein, the value range of the seventh temperature threshold is greater than or equal to 110℃ and less than or equal to 140℃; the value range of the eighth temperature threshold is greater than or equal to 110℃ and less than or equal to 140℃; and the value range of the ninth temperature threshold is greater than or equal to 90℃ and less than or equal to 105℃.

[0056] In this technical solution, during the cooking operation of the cooking equipment, the cooking equipment continuously judges whether the temperature of the first zone and the temperature of the second zone have reached the maximum temperature limit. The maximum temperature limit of the first zone is the aforementioned seventh temperature threshold, and the maximum temperature limit of the second zone is the aforementioned eighth temperature threshold.

[0057] When the first temperature value of the first region reaches the seventh temperature threshold mentioned above, or when the second temperature value of the second region reaches the eighth temperature threshold mentioned above, overheat protection is triggered. At this time, all heating loads, including the first heating element and the second heating element, are controlled to stop working. The first heating element and the second heating element are allowed to cool naturally to below the ninth temperature threshold before the heating process is resumed.

[0058] By determining whether the temperature in each zone has reached the maximum temperature limit threshold, dry burning can be prevented, thus improving the reliability and safety of cooking equipment.

[0059] For example, the range of the seventh temperature threshold is 110°C to 140°C. For example, the seventh temperature threshold is 112°C.

[0060] For example, the range of the eighth temperature threshold is 110°C to 140°C. For example, the eighth temperature threshold is 125°C.

[0061] For example, the range of the ninth temperature threshold is 90°C to 105°C. For example, the ninth temperature threshold is 100°C.

[0062] The technical solution of this application can realize the protection against dry burning of cooking equipment and improve the safety of cooking equipment.

[0063] Optionally, in response to a cooking start signal, while controlling the first heating element and the second heating element to continuously heat based on a target heating power, the control method further includes: starting a timer; and the control method further includes: controlling the cooking device to end cooking when the timer duration reaches the target cooking duration corresponding to the cooking start signal.

[0064] In this technical solution, the cooking device cooks based on the cooking time set by the user. This cooking time can be manually entered by the user or calculated based on the cooking mode or cooking program selected by the user. This application does not limit this.

[0065] When cooking begins, the main control chip of the cooking device generates a cooking start signal. Upon detecting this signal, a timer starts counting down. When the timer duration matches the user-set target cooking time, the cooking device determines that cooking is complete and stops operating.

[0066] In some implementations, the cooking device shuts off the first and second heating elements after cooking has ended.

[0067] In other implementations, the cooking device enters a heat preservation phase after cooking has finished.

[0068] The technical solution of this application is based on cooking time control of the cooking equipment to carry out cooking operations, which can achieve reliable cooking.

[0069] In some technical solutions of this application, optionally, at least two points on the first heating element are at different distances from the outer wall of the inner pot in the radial direction of the inner pot; and / or at least two points on the second heating element are at different distances from the outer wall of the inner pot in the radial direction of the inner pot.

[0070] In this technical solution, the inner pot of the cooking equipment is not necessarily round. For some products, the inner pot may be cubic in shape, i.e., a square pot. Traditional heating elements are generally arranged in a circular coil, which results in uneven radial distances between the heating element and the pot body. That is, the first and second heating elements are not equidistant from the inner pot in the radial direction. This can lead to different heating effects on different areas of the inner pot by the two heating elements, affecting the overall heating performance.

[0071] In response, the technical solution of this application sets up dual temperature sensors. During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperature of the first area and the second area. Based on the first temperature and the second temperature, the cooking device is controlled to perform cooking operations. By using dual-zone temperature control, the uniformity of heating of the inner pot by the heating element is improved, thereby ensuring the heating effect.

[0072] A second aspect of this application provides a control device for a cooking apparatus. The cooking apparatus includes an inner pot, a first heating element, and a second heating element. The first heating element is disposed opposite to a first region of the inner pot, and the second heating element is disposed opposite to a second region of the inner pot. The heating power of the first heating element is greater than the heating power of the second heating element. The control device includes:

[0073] The control module is used to control the first heating element and the second heating element to continuously heat based on the target heating power in response to the cooking start signal; the acquisition module is used to acquire the first temperature of the first region and the second temperature of the second region; the control module is also used to adjust the operating parameters of the first heating element and / or the second heating element based on the first temperature and the second temperature.

[0074] In this technical solution, the cooking equipment includes, but is not limited to, rice cookers, slow cookers, electric pressure cookers, and electric fryers. The cooking equipment includes an inner pot, which is disposed within the main body of the cooking equipment and used to hold the food to be cooked. Outside the inner pot, a first heating element and a second heating element are disposed facing the outer wall of the inner pot. Exemplarily, the first heating element is located on the periphery of the bottom wall of the inner pot, and the second heating element is located at the center of the bottom wall of the inner pot, such that the first heating element surrounds the second heating element.

[0075] In this design, the first heating element is defined as the outer ring heating element, and the second heating element is defined as the inner ring heating element. The first heating element can cover a larger area of ​​the bottom wall of the inner pot, and the area covered by the first heating element is called the first region. The second heating element can cover the center of the bottom wall of the inner pot, and the area covered by the second heating element is called the second region. It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element is greater than the heating power of the second heating element, enabling the dual heating elements to heat the cooking device more evenly.

[0076] Since the cooking device of this application is designed with dual heating elements, in order to improve the temperature control accuracy, the cooking device of this application is also equipped with dual temperature sensors. For example, the temperature sensors can be NTC (Negative Temperature Coefficient thermistor).

[0077] When the cooking device is performing a cooking operation, the user puts the ingredients to be cooked and water and other auxiliary materials into the inner pot, and sets the cooking mode. The main control chip of the cooking device determines parameters such as the target cooking temperature and target cooking time based on the cooking mode, and generates a cooking start signal when the user inputs to start cooking or when the user's reserved cooking time arrives.

The heating power of the first and second heating elements based on the target heating power can be the same or different. For example, the first heating element continuously heats based on a first target heating power, and the second heating element continuously heats based on a second target heating power.

[0079] During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperatures of the first and second regions, obtaining a first temperature and a second temperature. Since the first heating element is oriented towards the first region and the second heating element is oriented towards the second region, the first temperature better reflects the heating effect of the first heating element, and the second temperature better reflects the heating effect of the second heating element.

[0080] Based on the first temperature and the second temperature, the cooking equipment is controlled to perform cooking operations. Specifically, the operating parameters of at least one of the first heating element and the second heating element are used to achieve dual-zone temperature control, thereby enabling more precise temperature control of the cooking process and improving the cooking effect of the cooking equipment.

[0082] The fourth aspect of this application provides a read storage medium having a program or instructions stored thereon. When the program or instructions are executed by a processor, they implement the steps of the control method of the cooking device provided in any of the above technical solutions, and therefore include all of its beneficial effects. To avoid repetition, these will not be repeated here.

[0083] The fifth aspect of this application provides a cooking apparatus, including a control device for the cooking apparatus as provided in any of the above technical solutions; and / or a readable storage medium as provided in any of the above technical solutions, and therefore also includes all of its beneficial effects, which will not be repeated here to avoid repetition.

[0084] Optionally, in any of the above technical solutions, the cooking device further includes: an inner pot; a first heating element, the first heating element being disposed in a first region facing the bottom wall of the inner pot; and a second heating element, the second heating element being disposed in a second region facing the bottom wall of the inner pot, the first heating element being disposed around the second heating element, and the heating power of the first heating element being greater than the heating power of the second heating element.

It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element is greater than the heating power of the second heating element, enabling the dual heating elements to heat the cooking device more evenly.

[0087] In any of the above technical solutions, optionally, in the radial direction of the inner pot, at least two points on the first heating element are at different distances from the outer wall of the inner pot; and / or in the radial direction of the inner pot, at least two points on the second heating element are at different distances from the outer wall of the inner pot.

Based on the first temperature and the second temperature, the cooking device is controlled to perform cooking operations.

[0090] Optionally, in any of the above technical solutions, the cooking device further includes: a first temperature detection component, which is disposed in a first region and is used to detect a first temperature in the first region; and a second temperature detection component, which is disposed in a second region and is used to detect a second temperature in the second region.

[0091] In this technical solution, the cooking device features a dual-heating element design. To improve temperature control accuracy, the cooking device of this application also incorporates dual temperature sensors.

Detailed Implementation

[0104] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0105] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0106] The following reference Figures 1 to 6 This application describes a control method and apparatus for a cooking device, a readable storage medium, and a cooking device according to some embodiments thereof.

[0107] In some embodiments of this application, a method for controlling a cooking device is provided. Figure 1 The following are schematic diagrams illustrating the structure of a cooking apparatus according to some embodiments of this application, such as... Figure 1As shown, the cooking device 100 includes an inner pot 102, a first heating element 104, and a second heating element 106. The first heating element 104 is disposed opposite to a first region of the inner pot 102, and the second heating element 106 is disposed opposite to a second region of the inner pot. The heating power of the first heating element 104 is greater than the heating power of the second heating element 106.

[0108] Figure 2 A flowchart illustrating a control method for a cooking apparatus according to some embodiments of this application is shown, such as... Figure 2 As shown, the control methods include:

[0109] Step 202: In response to the cooking start signal, control the first heating element and the second heating element to continue heating based on the target heating power;

[0110] Step 204: Obtain the first temperature of the first region and the second temperature of the second region;

[0111] Step 206: Based on the first temperature and the second temperature, adjust the operating parameters of the first heating element and / or the second heating element.

[0112] In this embodiment, the cooking device includes, but is not limited to, a rice cooker, a slow cooker, an electric pressure cooker, and an electric fryer. The cooking device includes an inner pot, which is disposed within the main body of the cooking device and used to hold the food to be cooked. Outside the inner pot, a first heating element and a second heating element are disposed facing the outer wall of the inner pot. Exemplarily, the first heating element is located on the periphery of the bottom wall of the inner pot, and the second heating element is located at the center of the bottom wall of the inner pot, such that the first heating element surrounds the second heating element. Exemplarily, the first heating element is disposed facing the bottom wall of the inner pot, and the second heating element is disposed around the side wall of the inner pot.

[0113] In this design, the first heating element is defined as the outer ring heating element, and the second heating element is defined as the inner ring heating element. The first heating element can cover a larger area of ​​the bottom wall of the inner pot, and the area covered by the first heating element is called the first region. The second heating element can cover the center of the bottom wall of the inner pot, and the area covered by the second heating element is called the second region. It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element is greater than the heating power of the second heating element, enabling the dual heating elements to heat the cooking device more evenly.

[0114] Since the cooking device of this application is designed with dual heating elements, in order to improve the temperature control accuracy, the cooking device of this application is also equipped with dual temperature sensors. For example, the temperature sensors can be NTC (Negative Temperature Coefficient thermistor).

[0115] When the cooking device is performing a cooking operation, the user puts the ingredients to be cooked and water and other auxiliary materials into the inner pot, and sets the cooking mode. The main control chip of the cooking device determines parameters such as the target cooking temperature and target cooking time based on the cooking mode, and generates a cooking start signal when the user inputs to start cooking or when the user's reserved cooking time arrives.

[0116] After detecting a cooking start signal, the main control chip of the cooking device controls the first and second heating elements to begin heating. In the initial cooking stage, the purpose of the first and second heating elements is to rapidly heat the inner pot; both heating elements continuously heat during this period. This stage is referred to as the rapid heating stage. For example, the first and second heating elements continuously heat based on a target heating power. The heating power of the first and second heating elements based on the target heating power can be the same or different. For example, the first heating element continuously heats based on a first target heating power, and the second heating element continuously heats based on a second target heating power.

[0117] During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperatures of the first and second regions, obtaining a first temperature and a second temperature. Since the first heating element is oriented towards the first region and the second heating element is oriented towards the second region, the first temperature better reflects the heating effect of the first heating element, and the second temperature better reflects the heating effect of the second heating element.

[0118] Based on the first temperature and the second temperature, the cooking equipment is controlled to perform cooking operations. Specifically, the operating parameters of at least one of the first heating element and the second heating element are used to achieve dual-zone temperature control, thereby enabling more precise temperature control of the cooking process and improving the cooking effect of the cooking equipment.

[0119] In some embodiments of this application, optionally, the operating parameters include heating duration. Adjusting the operating parameters of the first heating element and / or the second heating element based on a first temperature and a second temperature includes: adjusting the heating duration of the first heating element and the second heating element when either the first temperature or the second temperature is greater than a temperature threshold; wherein the temperature threshold is associated with the target cooking temperature corresponding to the cooking start signal.

[0120] In this embodiment, the operating parameters of the first heating element and the second heating element include heating duration. For example, the heating duration can be the total heating duration of the heating element in one heating cycle, or it can be the heating duration and the interval duration when the heating element is performing intermittent heating.

[0121] During the cooking process, the cooking equipment continuously monitors the temperatures of the first and second zones, as mentioned above. When either the first temperature or the second temperature exceeds a certain threshold, it indicates that the pot temperature has reached a certain level. At this point, the cooking equipment transitions from a rapid heating phase to an intermittent heating phase. In this phase, the heating duration of the first and second heating elements is adjusted to ensure intermittent heating. This avoids heat buildup caused by continuous heating and overheating due to temperature sensor lag, ensuring that the actual cooking temperature always matches the target cooking temperature.

[0122] The temperature threshold mentioned above is determined based on the target cooking temperature. For example, the temperature threshold can be calculated based on the target cooking temperature and a preset offset temperature value.

[0123] This application embodiment prevents the cooking temperature of the cooking equipment from exceeding the target cooking temperature by transitioning from a rapid heating phase to an intermittent heating phase when the temperature conditions are met, thereby improving the cooking effect of the cooking equipment.

[0124] In some embodiments of this application, optionally, the temperature threshold includes a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is determined based on a target cooking temperature and a first preset temperature value, and the second temperature threshold is determined based on the target cooking temperature and the second preset temperature value; when either the first temperature or the second temperature is greater than the temperature threshold, adjusting the heating duration of the first heating element and the second heating element includes:

[0125] When the first temperature is greater than the first temperature threshold, or when the second temperature is greater than the second threshold temperature, the heating time of the first heating element and the second heating element is adjusted; wherein, the range of the first preset temperature value is greater than or equal to 8℃ and less than or equal to 15℃; the range of the second preset temperature value is greater than or equal to 8℃ and less than or equal to 15℃.

[0126] In this embodiment, the temperature threshold specifically includes a first temperature threshold corresponding to the first region and a second temperature threshold corresponding to the second region. When determining whether a temperature threshold is exceeded, the first temperature is compared with the first temperature threshold, and the second temperature is compared with the second temperature threshold. When either the first temperature is greater than the first temperature threshold or the second temperature is greater than the second temperature threshold, it is determined that the conditions for switching from the rapid heating stage to the intermittent heating stage are met.

[0127] The first temperature threshold is determined based on the sum of the target cooking temperature and the first preset temperature. Assuming the target cooking temperature for this cooking operation is T, and the first preset temperature is d1, then the first temperature threshold T1 = T - d1. Similarly, assuming the second preset temperature is d2, then the second temperature threshold T2 = T - d2.

[0128] For example, 8℃≤d1≤15℃. For example, 8℃≤d2≤15℃.

[0129] For example, d1 = 10°C. For example, d2 = 10°C.

[0130] This application embodiment enables precise control of cooking temperature by setting temperature thresholds for different regions.

[0131] In some embodiments of this application, adjusting the heating duration of the first heating element and the second heating element includes: controlling the first heating element to heat for a first duration in each first heating cycle, and controlling the second heating element to heat for a second duration in each second heating cycle; wherein the cycle length of the first heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; the value range of the first duration is greater than or equal to 4 seconds and less than or equal to 8 seconds; the cycle length of the second heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; and the value range of the second duration is greater than or equal to 4 seconds and less than or equal to 8 seconds.

[0132] In this embodiment, when controlling the first heating element and the second heating element to heat alternately, the interval heating is achieved by adjusting the heating duration of the first heating element and the second heating element in each heating cycle.

[0133] For example, the first heating element heats based on a first heating cycle, wherein in each first heating cycle, the first heating element continuously heats for a first duration and then stops heating until the next first heating cycle begins, and then continues heating for a first duration, and so on.

[0134] Similarly, the second heating element heats based on the second heating cycle. In each second heating cycle, the second heating element continuously heats for a second duration and then stops heating until the next second heating cycle begins, after which it continues heating for a second duration.

[0135] For example, the cycle length of the first heating cycle is 10 to 30 seconds. Taking a cycle length of 10 seconds and a duration of 5 seconds as an example, in each first heating cycle, the first heating element is heated for 5 seconds and then stopped for 5 seconds until it enters the next first cycle of 10 seconds, where it is heated for another 5 seconds and then stopped for 5 seconds.

[0136] For example, the cycle length of the second heating cycle is 10 to 30 seconds. Taking a cycle length of 15 seconds and a duration of 8 seconds as an example, in each second heating cycle, the second heating element heats for 8 seconds and then stops heating for 7 seconds until it enters the next second cycle of 15 seconds, where it heats for another 8 seconds and then stops heating for 7 seconds.

[0137] This application embodiment achieves an intermittent heating mode by controlling the heating duration of the first heating element and the second heating element in each heating cycle, thereby avoiding problems such as overheating and scorching, and realizing precise control of heating.

[0138] In some embodiments of this application, optionally, the operating parameters further include heating power; after adjusting the heating duration of the first heating element and the second heating element, the control method further includes: when the first temperature is greater than a third temperature threshold and the second temperature is greater than a fourth temperature threshold, controlling the second heating element to stop heating, and controlling the first heating element to adjust its heating power so that the first temperature and the second temperature match the target cooking temperature; wherein, the third temperature threshold is determined based on the target cooking temperature and a third preset temperature value, the fourth temperature threshold is determined based on the target cooking temperature and a fourth preset temperature value, the third preset temperature value is greater than or equal to 3℃ and less than or equal to 8℃; the fourth preset temperature value is greater than or equal to 0.5℃ and less than or equal to 3℃.

[0139] In this embodiment, the first heating element is an outer ring heating element, and the second heating element is an inner pot heating element. The outer ring heating element can heat a larger area of ​​the bottom of the inner pot, and the second heating element can heat the center of the bottom of the inner pot.

[0140] When the first temperature value of the first zone is greater than the third temperature threshold, and at the same time the second temperature value of the second zone is greater than the fourth temperature threshold, it means that the temperature of the inner pot and the food has reached the target cooking temperature. At this time, the second heating element of the inner ring is controlled to stop heating, and the heating power of the first heating element of the outer ring is adjusted so that the temperature of the inner pot and the food is maintained at the set target cooking temperature, thereby ensuring that the cooking effect matches the target cooking temperature set by the cooking program.

[0141] For example, let the target cooking temperature be T, the third temperature threshold be T3, and the third preset temperature be d3, then T3 = T - d3. Similarly, let the fourth temperature threshold be T4 and the fourth preset temperature be d4, then T4 = T - d4.

[0142] For example, 3℃≤d3≤8℃. For example, 0.5℃≤d4≤3℃.

[0143] For example, d3 = 5℃. For example, d4 = 1℃.

[0144] In this embodiment, when both the first and second regions of the inner pot reach near the target set temperature, the inner ring heating element is controlled to stop heating, while the heating power of the outer ring heating element is adjusted. This enables the temperature of the inner pot and the food to be maintained at the target cooking temperature, ensuring that the cooking effect meets expectations.

[0145] In some embodiments of this application, optionally, after adjusting the heating time of the first heating element and the second heating element, the control method further includes: when the first temperature is less than a fifth temperature threshold and the second temperature is less than a sixth temperature threshold, controlling the first heating element and the second heating element to continuously heat based on the target heating power; wherein the fifth temperature threshold is determined based on the target cooking temperature and a fifth preset temperature value, the sixth temperature threshold is determined based on the target cooking temperature and a sixth preset temperature value, the fifth preset temperature value is greater than or equal to 5°C and less than or equal to 10°C; the sixth preset temperature value is greater than or equal to 1°C and less than or equal to 5°C.

[0146] In this embodiment, after the cooking device leaves the rapid heating stage and enters the intermittent heating stage, if the temperature of the first area is less than the fifth temperature threshold and the temperature of the second area is less than the sixth temperature threshold, it indicates that the temperature of the inner pot and the food has dropped. At this time, the first heating element and the second heating element are controlled again to continue heating based on the target heating power in the manner of the rapid heating stage, so that the temperature of the inner pot and the food can quickly return to the target cooking temperature.

[0147] For example, let the target cooking temperature be T, the fifth temperature threshold be T5, and the fifth preset temperature be d5, then T5 = T - d5. Similarly, let the sixth temperature threshold be T6 and the sixth preset temperature be d6, then T6 = T - d6.

[0148] For example, 5℃≤d5≤10℃. For example, 1℃≤d6≤5℃.

[0149] For example, d5 = 7°C. For example, d6 = 2°C.

[0150] In this embodiment, after the temperature of the first and second regions of the inner pot decreases, the cooking equipment is controlled to return to the rapid heating phase, thereby preventing the temperature of the inner pot and the food from decreasing and ensuring the cooking effect.

[0151] In some embodiments of this application, optionally, controlling the first heating element and the second heating element to continuously heat based on a target heating power includes: controlling the first heating element to continuously heat at a first heating power, and controlling the second heating element to continuously heat at a second heating power; wherein the first heating power is the maximum heating power of the first heating element, and the second heating power is the maximum heating power of the second heating element.

[0152] In this embodiment, during the rapid heating phase, the first heating element can be controlled to continuously heat based on the first heating power, while the second heating element can be controlled to continuously heat based on the second heating power.

[0153] For example, the first heating power is the maximum heating power of the first heating element, and the second heating power is the maximum heating power of the second heating element.

[0154] For example, if the first heating element has specifications of 220V, 50Hz, and 1000W, then the first heating power is 1000W. If the second heating element has specifications of 220V, 50Hz, and 500W, then the second heating power is 500W.

[0155] This embodiment of the application controls both heating elements to continuously heat at their maximum power during the rapid heating phase, which can quickly increase the temperature of the inner pot and the food, thereby improving cooking efficiency.

[0156] In some embodiments of this application, optionally, when the first temperature is greater than a seventh temperature threshold or the second temperature is greater than an eighth temperature threshold, the first heating element and the second heating element are both controlled to stop heating until the first temperature and the second temperature are both less than a ninth temperature threshold, at which point the first heating element and the second heating element are controlled to resume heating; wherein, the value range of the seventh temperature threshold is greater than or equal to 110°C and less than or equal to 140°C; the value range of the eighth temperature threshold is greater than or equal to 110°C and less than or equal to 140°C; and the value range of the ninth temperature threshold is greater than or equal to 90°C and less than or equal to 105°C.

[0157] In this embodiment, during the cooking operation of the cooking device, the cooking device continuously determines whether the temperature of the first region and the temperature of the second region have reached the maximum temperature limit. The maximum temperature limit of the first region is the aforementioned seventh temperature threshold, and the maximum temperature limit of the second region is the aforementioned eighth temperature threshold.

[0158] When the first temperature value of the first region reaches the seventh temperature threshold mentioned above, or when the second temperature value of the second region reaches the eighth temperature threshold mentioned above, overheat protection is triggered. At this time, all heating loads, including the first heating element and the second heating element, are controlled to stop working. The first heating element and the second heating element are allowed to cool naturally to below the ninth temperature threshold before the heating process is resumed.

[0159] By determining whether the temperature in each zone has reached the maximum temperature limit threshold, dry burning can be prevented, thus improving the reliability and safety of cooking equipment.

[0160] For example, the range of the seventh temperature threshold is 110°C to 140°C. For example, the seventh temperature threshold is 112°C.

[0161] For example, the range of the eighth temperature threshold is 110°C to 140°C. For example, the eighth temperature threshold is 125°C.

[0162] For example, the range of the ninth temperature threshold is 90°C to 105°C. For example, the ninth temperature threshold is 100°C.

[0163] The embodiments of this application can realize the protection against dry burning of cooking equipment, thereby improving the safety of cooking equipment.

[0164] In some embodiments of this application, optionally, while controlling the first heating element and the second heating element to continuously heat based on the target heating power in response to the cooking start signal, the control method further includes: starting a timer; and the control method further includes: controlling the cooking device to end cooking when the timer duration reaches the target cooking duration corresponding to the cooking start signal.

[0165] In this embodiment, the cooking device cooks based on a cooking time set by the user. This cooking time can be manually entered by the user or calculated based on the cooking mode or cooking program selected by the user. This embodiment does not limit this.

[0166] When cooking begins, the main control chip of the cooking device generates a cooking start signal. Upon detecting this signal, a timer starts counting down. When the timer duration matches the user-set target cooking time, the cooking device determines that cooking is complete and stops operating.

[0167] In some implementations, the cooking device shuts off the first and second heating elements after cooking has ended.

[0168] In other implementations, the cooking device enters a heat preservation phase after cooking has finished.

[0169] The embodiments of this application control the cooking equipment based on cooking time, which enables reliable cooking.

[0170] In some embodiments of this application, optionally, at least two points on the first heating element are at different distances from the outer wall of the inner pot in the radial direction of the inner pot; and / or at least two points on the second heating element are at different distances from the outer wall of the inner pot in the radial direction of the inner pot.

[0171] In this embodiment, the inner pot of the cooking device is not necessarily circular. For some products, the inner pot may be cubic, i.e., a square pot. Traditional heating elements are generally arranged in a circular coil, which results in uneven radial distances between the heating element and the pot body. That is, the first and second heating elements are not equidistant from the inner pot in the radial direction. This can lead to different heating effects on different areas of the inner pot by the two heating elements, affecting the overall heating performance.

[0172] In response, the technical solution of this application sets up dual temperature sensors. During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperature of the first area and the second area. Based on the first temperature and the second temperature, the cooking device is controlled to perform cooking operations. By using dual-zone temperature control, the uniformity of heating of the inner pot by the heating element is improved, thereby ensuring the heating effect.

[0173] In some embodiments of this application, optionally taking an electric slow cooker as an example, the embodiments of this application are described in detail below:

[0174] The electric slow cooker features a high-power outer ring heat pipe and a low-power inner ring heat pipe. The two heat pipes heat simultaneously or alternately. Due to its higher power, the outer ring heat pipe can heat a wider area of ​​the bottom. An NTC1 sensor is installed on the outer ring of the bottom to collect the temperature. An NTC2 sensor is installed on the center ring of the bottom to collect the center temperature. The program can combine NTC1 and NTC2 sensing to improve temperature accuracy.

[0175] Users select the function, set the temperature and time, and press start to begin cooking. The machine then operates. The corresponding function indicator light illuminates, displays a countdown, and monitors the pot temperature in real time.

[0176] The machine performs continuous monitoring. If the temperature of NTC1 exceeds Temp1 (Temp1 is the over-temperature protection temperature for NTC1, set above 120℃), or if the temperature of NTC2 exceeds Temp2 (Temp2 is the over-temperature protection temperature for NTC2, set above 120℃), it will initiate over-temperature protection, stopping all heating loads. Normal cooking can resume once the temperature has cooled to below 100℃.

[0177] The machine first performs the initial cooking phase. Both the outer and inner ring heat pipes operate at full power, rapidly heating the pot. If the NTC1 temperature is greater than (set temperature - d1), or the NTC2 temperature is greater than (set temperature - d2), the conditions are met, exceeding the initial cooking temperature, and the process proceeds to the next phase. d1 is the NTC1 initial cooking offset temperature, typically set above 10°C. d2 is the NTC2 initial cooking offset temperature, typically set above 10°C.

[0178] The outer ring heat pipe heats at intervals of (t1, Y1), where t1 is the heating on-time, typically set to 5 seconds or more, and Y1 is the heating cycle, typically set to 10 seconds or more. The inner ring heat pipe heats at intervals of (t2, Y2), where t2 is the heating on-time, typically set to 5 seconds or more, and Y2 is the heating cycle, typically set to 10 seconds or more.

[0179] If the machine's NTC1 temperature is greater than (set temperature - d3) and the NTC2 temperature is greater than (set temperature - d4), the inner ring heat pipe stops heating, and the outer ring heat pipe adjusts its power for heating (adjusting the power to maintain temperature balance based on the actual menu performance). Otherwise, return to process (3) for cooking.

[0180] d3 is the offset temperature value for the NTC1 setting, which is generally set to 5°C or higher. d4 is the offset temperature value for the NTC2 setting, which is generally set to 1°C or higher.

[0181] If NTC1 temperature < (set temperature - d5) and NTC2 temperature < (set temperature - d6), then return to the first-stroke process for cooking. Otherwise, proceed to process (3) for cooking.

[0182] d5 is the offset value for the NTC1 operating temperature recovery, which is generally set to 7°C or higher. d6 is the offset value for the NTC2 operating temperature recovery, which is generally set to 2°C or higher.

[0183] The program will return to standby mode when the countdown reaches 0.

[0184] For example, Figure 3 A flowchart illustrating a control method for a cooking apparatus according to some embodiments of this application is shown, such as... Figure 3 As shown, the method includes:

[0185] Step 302: Select cooking parameters and start cooking.

[0186] Users select the cooking function, set the temperature and time, and press the start button to begin cooking.

[0187] Step 304: Start cooking timer, begin cooking, and monitor the pot temperature in real time.

[0188] Once cooking begins, the indicator light illuminates and a countdown timer starts.

[0189] Step 306: Determine whether NTC1 > Temp1 or NTC2 > Temp2. ​​If yes, proceed to step 308; otherwise, proceed to step 310.

[0190] Wherein, NTC1 is the temperature of the first region, NTC2 is the temperature of the second region, Temp1 is the NCT1 ultra-high temperature threshold, and Temp2 is the NCT2 ultra-high temperature threshold.

[0191] Step 308, High Temperature Protection.

[0192] When the high-temperature protection is triggered, all heating stops and the temperature is allowed to cool down to 100°C.

[0193] Step 310: The outer and inner ring heat pipes are heated at full power.

[0194] Step 312: Determine whether NTC1 > T1 and NTC2 > T2 are satisfied. If yes, proceed to step 314; otherwise, return to step 310.

[0195] Where T1 = T - d1, T2 = T - d2, T is the set temperature, and d1 and d2 are constants.

[0196] Step 314: The outer and inner ring heat pipes are heated alternately.

[0197] The outer ring heat pipe heats at (t1, Y1), where t1 is the heating start-up time (generally set to 5 seconds or more) and Y1 is the heating cycle (generally set to 10 seconds or more). The inner ring heat pipe heats at (t2, Y2), where t2 is the heating start-up time (generally set to 5 seconds or more) and Y2 is the heating cycle (generally set to 10 seconds or more).

[0198] Step 316: Determine if NTC1 > T3 and NTC2 > T4. If yes, proceed to step 318; otherwise, return to step 314.

[0199] Where T3 = T - d3, T4 = T - d4, T is the set temperature, and d3 and d4 are constants.

[0200] Step 318: The inner ring heat pipe stops heating, and the outer ring heat pipe adjusts its heating power.

[0201] Step 320: Determine if NTC1 < T5 and NTC2 < T6. If yes, return to step 314; otherwise, proceed to step 322.

[0202] Where T5 = T - d5, T6 = T - d6, T is the set temperature, and d5 and d6 are constants.

[0203] Step 322: Determine whether the heating time has reached the set time; if yes, end the process; otherwise, return to step 318.

[0204] In some embodiments of this application, a control device for a cooking apparatus is provided. The cooking apparatus includes an inner pot, a first heating element, and a second heating element. The first heating element is disposed opposite to a first region of the inner pot, and the second heating element is disposed opposite to a second region of the inner pot. The heating power of the first heating element is greater than the heating power of the second heating element.

[0206] The control module 402 is used to control the first heating element and the second heating element to continuously heat based on the target heating power in response to the cooking start signal; the acquisition module 404 is used to acquire the first temperature of the first region and the second temperature of the second region; the control module 402 is also used to adjust the operating parameters of the first heating element and / or the second heating element based on the first temperature and the second temperature.

[0207] In this embodiment, the cooking device includes, but is not limited to, a rice cooker, a slow cooker, an electric pressure cooker, and an electric fryer. The cooking device includes an inner pot, which is disposed within the main body of the cooking device and is used to hold the food to be cooked. Outside the inner pot, a first heating element and a second heating element are disposed facing the outer wall of the inner pot. Exemplarily, the first heating element is located on the periphery of the bottom wall of the inner pot, and the second heating element is located at the center of the bottom wall of the inner pot, such that the first heating element surrounds the second heating element.

[0208] In this design, the first heating element is defined as the outer ring heating element, and the second heating element is defined as the inner ring heating element. The first heating element can cover a larger area of ​​the bottom wall of the inner pot, and the area covered by the first heating element is called the first region. The second heating element can cover the center of the bottom wall of the inner pot, and the area covered by the second heating element is called the second region. It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element is greater than the heating power of the second heating element, enabling the dual heating elements to heat the cooking device more evenly.

[0209] Since the cooking device of this application is designed with dual heating elements, in order to improve the temperature control accuracy, the cooking device of this application is also equipped with dual temperature sensors. For example, the temperature sensors can be NTC (Negative Temperature Coefficient thermistor).

[0210] When the cooking device is performing a cooking operation, the user puts the ingredients to be cooked and water and other auxiliary materials into the inner pot, and sets the cooking mode. The main control chip of the cooking device determines parameters such as the target cooking temperature and target cooking time based on the cooking mode, and generates a cooking start signal when the user inputs to start cooking or when the user's reserved cooking time arrives.

[0211] After detecting a cooking start signal, the main control chip of the cooking device controls the first and second heating elements to begin heating. In the initial cooking stage, the purpose of the first and second heating elements is to rapidly heat the inner pot; both heating elements continuously heat during this period. This stage is referred to as the rapid heating stage. For example, the first and second heating elements continuously heat based on a target heating power. The heating power of the first and second heating elements based on the target heating power can be the same or different. For example, the first heating element continuously heats based on a first target heating power, and the second heating element continuously heats based on a second target heating power.

[0212] During the continuous heating process of the first heating element and the second heating element, the cooking device continuously acquires the temperatures of the first and second regions, obtaining a first temperature and a second temperature. Since the first heating element is oriented towards the first region and the second heating element is oriented towards the second region, the first temperature better reflects the heating effect of the first heating element, and the second temperature better reflects the heating effect of the second heating element.

[0213] Based on the first temperature and the second temperature, the cooking equipment is controlled to perform cooking operations. Specifically, the operating parameters of at least one of the first heating element and the second heating element are used to achieve dual-zone temperature control, thereby enabling more precise temperature control of the cooking process and improving the cooking effect of the cooking equipment.

[0214] In some embodiments of this application, optionally, the operating parameters include heating duration. Based on a first temperature and a second temperature, the control module is further configured to adjust the heating duration of the first heating element and the second heating element when either the first temperature or the second temperature is greater than a temperature threshold; wherein the temperature threshold is associated with the target cooking temperature corresponding to the cooking start signal.

[0215] In this embodiment, the operating parameters of the first heating element and the second heating element include heating duration. For example, the heating duration can be the total heating duration of the heating element in one heating cycle, or it can be the heating duration and the interval duration when the heating element is performing intermittent heating.

[0216] During the cooking process, the cooking equipment continuously monitors the temperatures of the first and second zones, as mentioned above. When either the first temperature or the second temperature exceeds a certain threshold, it indicates that the pot temperature has reached a certain level. At this point, the cooking equipment transitions from a rapid heating phase to an intermittent heating phase. In this phase, the heating duration of the first and second heating elements is adjusted to ensure intermittent heating. This avoids heat buildup caused by continuous heating and overheating due to temperature sensor lag, ensuring that the actual cooking temperature always matches the target cooking temperature.

[0217] The temperature threshold mentioned above is determined based on the target cooking temperature. For example, the temperature threshold can be calculated based on the target cooking temperature and a preset offset temperature value.

[0218] This application embodiment prevents the cooking temperature of the cooking equipment from exceeding the target cooking temperature by transitioning from a rapid heating phase to an intermittent heating phase when the temperature conditions are met, thereby improving the cooking effect of the cooking equipment.

[0219] In some embodiments of this application, optionally, the temperature threshold includes a first temperature threshold and a second temperature threshold. The first temperature threshold is determined based on the target cooking temperature and a first preset temperature value, and the second temperature threshold is determined based on the target cooking temperature and the second preset temperature value. The control module is further configured to adjust the heating duration of the first heating element and the second heating element when the first temperature is greater than the first temperature threshold or the second temperature is greater than the second threshold temperature. The first preset temperature value is greater than or equal to 8°C and less than or equal to 15°C. The second preset temperature value is greater than or equal to 8°C and less than or equal to 15°C.

[0220] In this embodiment, the temperature threshold specifically includes a first temperature threshold corresponding to the first region and a second temperature threshold corresponding to the second region. When determining whether a temperature threshold is exceeded, the first temperature is compared with the first temperature threshold, and the second temperature is compared with the second temperature threshold. When either the first temperature is greater than the first temperature threshold or the second temperature is greater than the second temperature threshold, it is determined that the conditions for switching from the rapid heating stage to the intermittent heating stage are met.

[0221] The first temperature threshold is determined based on the sum of the target cooking temperature and the first preset temperature. Assuming the target cooking temperature for this cooking operation is T, and the first preset temperature is d1, then the first temperature threshold T1 = T - d1. Similarly, assuming the second preset temperature is d2, then the second temperature threshold T2 = T - d2.

[0222] For example, 8℃≤d1≤15℃. For example, 8℃≤d2≤15℃.

[0223] For example, d1 = 10°C. For example, d2 = 10°C.

[0224] This application embodiment enables precise control of cooking temperature by setting temperature thresholds for different regions.

[0225] In some embodiments of this application, the control module is further configured to control the first heating element to heat for a first duration in each first heating cycle, and to control the second heating element to heat for a second duration in each second heating cycle; wherein the cycle length of the first heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; the value range of the first duration is greater than or equal to 4 seconds and less than or equal to 8 seconds; the cycle length of the second heating cycle is greater than or equal to 10 seconds and less than or equal to 30 seconds; and the value range of the second duration is greater than or equal to 4 seconds and less than or equal to 8 seconds.

[0226] In this embodiment, when controlling the first heating element and the second heating element to heat alternately, the interval heating is achieved by adjusting the heating duration of the first heating element and the second heating element in each heating cycle.

[0227] For example, the first heating element heats based on a first heating cycle, wherein in each first heating cycle, the first heating element continuously heats for a first duration and then stops heating until the next first heating cycle begins, and then continues heating for a first duration, and so on.

[0228] Similarly, the second heating element heats based on the second heating cycle. In each second heating cycle, the second heating element continuously heats for a second duration and then stops heating until the next second heating cycle begins, after which it continues heating for a second duration.

[0229] For example, the cycle length of the first heating cycle is 10 to 30 seconds. Taking a cycle length of 10 seconds and a duration of 5 seconds as an example, in each first heating cycle, the first heating element is heated for 5 seconds and then stopped for 5 seconds until it enters the next first cycle of 10 seconds, where it is heated for another 5 seconds and then stopped for 5 seconds.

[0230] For example, the cycle length of the second heating cycle is 10 to 30 seconds. Taking a cycle length of 15 seconds and a duration of 8 seconds as an example, in each second heating cycle, the second heating element heats for 8 seconds and then stops heating for 7 seconds until it enters the next second cycle of 15 seconds, where it heats for another 8 seconds and then stops heating for 7 seconds.

[0231] This application embodiment achieves an intermittent heating mode by controlling the heating duration of the first heating element and the second heating element in each heating cycle, thereby avoiding problems such as overheating and scorching, and realizing precise control of heating.

[0232] In some embodiments of this application, optionally, the operating parameters further include heating power; the control module is further configured to control the second heating element to stop heating and control the first heating element to adjust the heating power when the first temperature is greater than the third temperature threshold and the second temperature is greater than the fourth temperature threshold, so that the first temperature and the second temperature match the target cooking temperature; wherein the third temperature threshold is determined based on the target cooking temperature and a third preset temperature value, the fourth temperature threshold is determined based on the target cooking temperature and a fourth preset temperature value, the third preset temperature value is greater than or equal to 3℃ and less than or equal to 8℃; the fourth preset temperature value is greater than or equal to 0.5℃ and less than or equal to 3℃.

[0233] In this embodiment, the first heating element is an outer ring heating element, and the second heating element is an inner pot heating element. The outer ring heating element can heat a larger area of ​​the bottom of the inner pot, and the second heating element can heat the center of the bottom of the inner pot.

[0234] When the first temperature value of the first zone is greater than the third temperature threshold, and at the same time the second temperature value of the second zone is greater than the fourth temperature threshold, it means that the temperature of the inner pot and the food has reached the target cooking temperature. At this time, the second heating element of the inner ring is controlled to stop heating, and the heating power of the first heating element of the outer ring is adjusted so that the temperature of the inner pot and the food is maintained at the set target cooking temperature, thereby ensuring that the cooking effect matches the target cooking temperature set by the cooking program.

[0235] For example, let the target cooking temperature be T, the third temperature threshold be T3, and the third preset temperature be d3, then T3 = T - d3. Similarly, let the fourth temperature threshold be T4 and the fourth preset temperature be d4, then T4 = T - d4.

[0236] For example, 3℃≤d3≤8℃. For example, 0.5℃≤d4≤3℃.

[0237] For example, d3 = 5℃. For example, d4 = 1℃.

[0238] In this embodiment, when both the first and second regions of the inner pot reach near the target set temperature, the inner ring heating element is controlled to stop heating, while the heating power of the outer ring heating element is adjusted. This enables the temperature of the inner pot and the food to be maintained at the target cooking temperature, ensuring that the cooking effect meets expectations.

[0239] In some embodiments of this application, optionally, the control module is further configured to control the first heating element and the second heating element to continuously heat based on the target heating power when the first temperature is less than the fifth temperature threshold and the second temperature is less than the sixth temperature threshold; wherein the fifth temperature threshold is determined based on the target cooking temperature and the fifth preset temperature value, the sixth temperature threshold is determined based on the target cooking temperature and the sixth preset temperature value, the fifth preset temperature value is greater than or equal to 5°C and less than or equal to 10°C; the sixth preset temperature value is greater than or equal to 1°C and less than or equal to 5°C.

[0240] In this embodiment, after the cooking device leaves the rapid heating stage and enters the intermittent heating stage, if the temperature of the first area is less than the fifth temperature threshold and the temperature of the second area is less than the sixth temperature threshold, it indicates that the temperature of the inner pot and the food has dropped. At this time, the first heating element and the second heating element are controlled again to continue heating based on the target heating power in the manner of the rapid heating stage, so that the temperature of the inner pot and the food can quickly return to the target cooking temperature.

[0241] For example, let the target cooking temperature be T, the fifth temperature threshold be T5, and the fifth preset temperature be d5, then T5 = T - d5. Similarly, let the sixth temperature threshold be T6 and the sixth preset temperature be d6, then T6 = T - d6.

[0242] For example, 5℃≤d5≤10℃. For example, 1℃≤d6≤5℃.

[0243] For example, d5 = 7°C. For example, d6 = 2°C.

[0244] In this embodiment, after the first and second regions of the inner pot are lowered, the cooking equipment is controlled to return to the rapid heating phase, thereby preventing the temperature of the inner pot and the food from dropping, thus ensuring the cooking effect.

[0245] In some embodiments of this application, optionally, the control module is further configured to control the first heating element to continuously heat at a first heating power and control the second heating element to continuously heat at a second heating power; wherein, the first heating power is the maximum heating power of the first heating element and the second heating power is the maximum heating power of the second heating element.

[0246] In this embodiment, during the rapid heating phase, the first heating element can be controlled to continuously heat based on the first heating power, while the second heating element can be controlled to continuously heat based on the second heating power.

[0247] For example, the first heating power is the maximum heating power of the first heating element, and the second heating power is the maximum heating power of the second heating element.

[0248] For example, if the first heating element has specifications of 220V, 50Hz, and 1000W, then the first heating power is 1000W. If the second heating element has specifications of 220V, 50Hz, and 500W, then the second heating power is 500W.

[0249] This embodiment of the application controls both heating elements to continuously heat at their maximum power during the rapid heating phase, which can quickly increase the temperature of the inner pot and the food, thereby improving cooking efficiency.

[0250] In some embodiments of this application, optionally, the control module is further configured to control both the first heating element and the second heating element to stop heating when the first temperature is greater than a seventh temperature threshold or the second temperature is greater than an eighth temperature threshold, until both the first temperature and the second temperature are less than a ninth temperature threshold, and then control the first heating element and the second heating element to resume heating; wherein, the value range of the seventh temperature threshold is greater than or equal to 110°C and less than or equal to 140°C; the value range of the eighth temperature threshold is greater than or equal to 110°C and less than or equal to 140°C; and the value range of the ninth temperature threshold is greater than or equal to 90°C and less than or equal to 105°C.

[0251] In this embodiment, during the cooking operation of the cooking device, the cooking device continuously determines whether the temperature of the first region and the temperature of the second region have reached the maximum temperature limit. The maximum temperature limit of the first region is the aforementioned seventh temperature threshold, and the maximum temperature limit of the second region is the aforementioned eighth temperature threshold.

[0252] When the first temperature value of the first region reaches the seventh temperature threshold mentioned above, or when the second temperature value of the second region reaches the eighth temperature threshold mentioned above, overheat protection is triggered. At this time, all heating loads, including the first heating element and the second heating element, are controlled to stop working. The first heating element and the second heating element are allowed to cool naturally to below the ninth temperature threshold before the heating process is resumed.

[0253] By determining whether the temperature in each zone has reached the maximum temperature limit threshold, dry burning can be prevented, thus improving the reliability and safety of cooking equipment.

[0254] For example, the range of the seventh temperature threshold is 110°C to 140°C. For example, the seventh temperature threshold is 112°C.

[0255] For example, the range of the eighth temperature threshold is 110°C to 140°C. For example, the eighth temperature threshold is 125°C.

[0256] For example, the range of the ninth temperature threshold is 90°C to 105°C. For example, the ninth temperature threshold is 100°C.

[0257] The embodiments of this application can realize the protection against dry burning of cooking equipment, thereby improving the safety of cooking equipment.

[0258] In some embodiments of this application, the control device may optionally include: a timing module for starting the timer; and a control module for controlling the cooking device to end cooking when the timer duration reaches the target cooking duration corresponding to the cooking start signal.

[0259] In this embodiment, the cooking device cooks based on a cooking time set by the user. This cooking time can be manually entered by the user or calculated based on the cooking mode or cooking program selected by the user. This embodiment does not limit this.

[0260] When cooking begins, the main control chip of the cooking device generates a cooking start signal. Upon detecting this signal, a timer starts counting down. When the timer duration matches the user-set target cooking time, the cooking device determines that cooking is complete and stops operating.

[0261] In some implementations, the cooking device shuts off the first and second heating elements after cooking has ended.

[0262] In other implementations, the cooking device enters a heat preservation phase after cooking has finished.

[0263] The embodiments of this application control the cooking equipment based on cooking time, which enables reliable cooking.

[0264] In some embodiments of this application, a control device for a cooking apparatus is provided. Figure 5 Structural block diagrams of the control device of a cooking apparatus according to some embodiments of this application are shown, such as... Figure 5 As shown, the control device 500 includes: a memory 502 for storing programs or instructions; and a processor 504 for executing programs or instructions to implement the steps of the control method for the cooking device provided in any of the above embodiments, and therefore also includes all its beneficial effects, which will not be described again here to avoid repetition.

[0265] In some embodiments of this application, a read storage medium is provided on which a program or instructions are stored. When the program or instructions are executed by a processor, they implement the steps of the control method of the cooking device provided in any of the above embodiments, and therefore include all its beneficial effects. To avoid repetition, these will not be repeated here.

[0266] In some embodiments of this application, a cooking apparatus is provided, including a control device for the cooking apparatus as provided in any of the above embodiments; and / or a readable storage medium as provided in any of the above embodiments, and therefore all its beneficial effects are also included, which will not be repeated here to avoid repetition.

[0267] In any of the above embodiments, optionally, as Figure 1 As shown, the cooking device 100 further includes: an inner pot 102; a first heating element 104, which is disposed toward a first region of the bottom wall of the inner pot 102; and a second heating element 106, which is disposed toward a second region of the bottom wall of the inner pot 102. The first heating element 104 is disposed around the second heating element 106, and the heating power of the first heating element 104 is greater than the heating power of the second heating element 106.

[0268] In this embodiment, the cooking device 100 includes, but is not limited to, a rice cooker, a slow cooker, an electric pressure cooker, and an electric fryer. The cooking device 100 includes an inner pot 102, which is disposed within the main body of the cooking device 100 and used to hold the food to be cooked. At the bottom of the inner pot 102, a first heating element 104 and a second heating element 106 are disposed facing the bottom wall of the inner pot 102. Exemplarily, the first heating element 104 is located on the periphery of the bottom wall of the inner pot 102, and the second heating element 106 is located at the center of the bottom wall of the inner pot 102, such that the first heating element 104 is arranged around the second heating element 106.

[0269] In this design, the first heating element 104 is defined as the outer ring heating element, and the second heating element 106 is defined as the inner ring heating element. The first heating element 104 can cover a larger area of ​​the bottom wall of the inner pot 102, and the area covered by the first heating element 104 is called the first region. The second heating element 106 can cover the center of the bottom wall of the inner pot 102, and the area covered by the second heating element 106 is called the second region. It is understood that the area of ​​the first region is larger than the area of ​​the second region, and the heating power of the first heating element 104 is greater than the power of the second heating element 106, so that the dual heating elements can heat the cooking device 100 more evenly.

[0270] In some embodiments of this application, optionally, at least two points on the first heating element 104 are at different distances from the outer wall of the inner pot 102 in the radial direction; and / or at least two points on the second heating element 106 are at different distances from the outer wall of the inner pot 102 in the radial direction.

[0271] In this embodiment, the inner pot 102 of the cooking device is not necessarily circular. For some products, the inner pot 102 may be cubic in shape, i.e., a square pot. Traditional heating elements are generally arranged in a circular coil, which results in uneven radial distances between the heating element and the pot body. Specifically, the first heating element 104 and the second heating element 106 are not equidistant from the inner pot 102 in the radial direction. This can lead to different heating effects on different areas of the inner pot 102 by the two heating elements, affecting the overall heating effect.

[0272] In response, the technical solution of this application sets up dual temperature sensors. During the continuous heating process of the first heating element 104 and the second heating element 106, the cooking device continuously acquires the temperature of the first and second zones. Based on the first and second temperatures, the cooking device is controlled to perform cooking operations. By using dual-zone temperature control, the uniformity of heating of the inner pot 102 by the heating elements is improved, thereby ensuring the heating effect.

[0273] In any of the above embodiments, optionally, as Figure 1 As shown, the cooking device 100 further includes: a first temperature detection component 108, which is disposed in a first region and is used to detect a first temperature in the first region; and a second temperature detection component 110, which is disposed in a second region and is used to detect a second temperature in the second region.

[0274] In this embodiment, the cooking device 100 features a dual heating element design. To improve temperature control accuracy, the cooking device 100 also incorporates dual temperature sensors. For example, the temperature sensors can be NTC (Negative Temperature Coefficient thermistors). During the continuous heating process of the first heating element 104 and the second heating element 106, the cooking device 100 continuously acquires the temperatures of the first and second regions, obtaining a first temperature and a second temperature. Since the first heating element 104 is oriented towards the first region and the second heating element 106 is oriented towards the second region, the first temperature better reflects the heating effect of the first heating element 104, and the second temperature better reflects the heating effect of the second heating element 106.

[0275] Based on the first temperature and the second temperature, the cooking device 100 is controlled to perform cooking operations. Specifically, the operating parameters of at least one of the first heating element 104 and the second heating element 106 are controlled to achieve dual-zone temperature control, thereby achieving more precise temperature control of the cooking process of the cooking device 100 and improving the cooking effect of the cooking device 100.

[0276] In any of the above embodiments, optionally, Figure 6Circuit diagrams of temperature detection components according to some embodiments of this application are shown. As shown in Figure 6, both the first temperature detection component 108 and the second temperature detection component 110 include: a probe ND1, which includes a first terminal and a second terminal; a first capacitor C1, whose first end is electrically connected to the first terminal, and whose second end is electrically connected to the second terminal, and whose second end is grounded; a first resistor R1, whose first end is electrically connected to the first end of the first capacitor C1, and whose second end is electrically connected to the second end of the first capacitor C1; a second resistor R2, whose first end is used to connect a power supply signal, and whose second end is electrically connected to the first end of the first resistor R1; a second capacitor C2, whose first end is electrically connected to the second end of the second resistor R2, and whose second end is grounded; and a third resistor R3, whose first end is electrically connected to the second end of the second resistor R2, and whose second end is electrically connected to the control device of the cooking equipment 100.

[0277] In this embodiment, the probe ND1 is an NTC thermistor probe ND1. Temperature detection is achieved through the NTC thermistor probe ND1, which has low hardware cost and is easy to implement.

[0278] The methods can be implemented in various ways depending on specific features and / or example applications. For example, these methods can be implemented by a combination of hardware, firmware, and / or software. For instance, in a hardware implementation, the processor can be implemented in one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, electronic devices, other device units for performing the functions described above, and / or combinations thereof.
