Description

Technical Field

[0001] This application relates to the field of cooking appliance technology, and more specifically to a control method for a cooking appliance and a cooking appliance employing the control method. Background Technology

[0002] Some cooking appliances have a timer function, allowing users to schedule meal times in advance. The appliance then automatically cooks the food at the designated time, providing the meal at the preset mealtime. Typically, users schedule breakfast for the next day the night before. The appliance will activate its fan while cooking to prevent overflow. The fan makes some noise, which can disturb the user's sleep, especially in the morning.

[0003] Therefore, a cooking appliance is needed to at least partially solve the above problems. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This summary section is not intended to limit the key and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, a first aspect of this application provides a method for controlling a cooking appliance, the cooking appliance having a preset function and an anti-overflow device, the anti-overflow device being used to prevent overflow during the boiling maintenance phase of the cooking process, the control method comprising:

[0006] For each cooking function with anti-overflow function, a first cooking process corresponding to the operation of the anti-overflow device and a second cooking process corresponding to the non-operation of the anti-overflow device are designed. The first cooking process has a first cooking time, the second cooking process has a second cooking time, the heating power of the boiling maintenance phase of the first cooking process is greater than the heating power of the boiling maintenance phase of the second cooking process, and the first cooking time is less than the second cooking time.

[0007] When the cooking appliance performs a non-preset cooking function, the first cooking process is used to carry out the cooking.

[0008] When the cooking appliance performs the scheduled cooking function, the second cooking process is used to perform cooking, and cooking begins at a time before the scheduled dining time, which is the second cooking duration; or, when the cooking appliance performs the scheduled cooking function, the second cooking process is used to perform cooking if preset conditions are met, and cooking begins at a time before the scheduled dining time, which is the second cooking duration.

[0009] According to this application, when the cooking appliance performs a preset cooking function, the anti-overflow device does not operate, thus preventing noise. To prevent overflow, when the cooking appliance performs a preset cooking function, the power to maintain the boiling phase is reduced, but the cooking time is extended to ensure the food is thoroughly cooked.

[0010] Optionally, the duration of the boiling maintenance phase in the first cooking process is shorter than the duration of the boiling maintenance phase in the second cooking process.

[0011] According to this application, when a cooking appliance performs a pre-set cooking function, it extends the working time of maintaining the boiling stage to ensure that the food is fully cooked.

[0012] Optionally, the time from the moment the user submits the reservation to the reservation time set by the user is the reservation duration, and the second cooking time is determined based on the first cooking time and the reservation duration; or the second cooking time is determined based on the first cooking time.

[0013] According to this application, when a cooking appliance performs a scheduled cooking function, the cooking time is referenced to the cooking time when the corresponding anti-overflow device is working, and the available reservation waiting time can also be taken into account to ensure that the finished food is provided at the user's preset dining time.

[0014] Optionally, the second cooking time is the sum of the first cooking time and the cooking compensation time.

[0015] The cooking compensation time is determined based on the reservation time; or the cooking compensation time is a preset value.

[0016] According to this application, when a cooking appliance performs a scheduled cooking function, the cooking time is increased by a compensation period based on the cooking time when the corresponding anti-overflow device is working. The method for setting the compensation period is flexible.

[0017] Optionally,

[0018] The cooking compensation time is determined based on the reservation time. When the reservation time falls within different time ranges, the cooking compensation time will be different.

[0019] The longer the reservation duration, the longer the cooking compensation duration; the shorter the reservation duration, the shorter the cooking compensation duration.

[0020] According to this application, as the reservation duration increases, more reservation waiting time becomes available, and extending the cooking time can improve the cooking effect.

[0021] Optionally,

[0022] When the reservation duration is within the first duration range, the cooking compensation duration is the first cooking compensation duration;

[0023] When the reservation duration is greater than the maximum value of the first duration range, the cooking compensation duration is greater than the first cooking compensation duration.

[0024] further,

[0025] When the reservation duration is within the first duration range, the cooking compensation duration is the first cooking compensation duration;

[0026] When the reservation duration is within the second duration range, the cooking compensation duration is the second cooking compensation duration;

[0027] When the reservation duration is within the third duration range, the cooking compensation duration is the first cooking compensation duration;

[0028] Wherein, the first time range, the second time range, and the third time range are continuous time intervals, the time value in the first time range is less than the time value in the second time range, the time value in the second time range is less than the time value in the third time range, the first cooking compensation time is less than the second cooking compensation time, and the second cooking compensation time is less than the third cooking compensation time.

[0029] further,

[0030] The first duration ranges from [0, 240) minutes, and the first cooking compensation duration is 4 to 14 minutes;

[0031] The second duration range is [240, 1080] minutes, and the second cooking compensation duration is 14 to 24 minutes;

[0032] The third duration range is (1080, 1440) minutes, and the third cooking compensation duration is 24 to 34 minutes.

[0033] According to this application, the method for determining the compensation period is simple.

[0034] Optionally, when the cooking functions are the same or when the amount of ingredients and the cooking functions are the same, the working time of the boiling maintenance phase of the second cooking process is equal to the sum of the working time of the boiling maintenance phase of the first cooking process and the cooking compensation time.

[0035] According to this application, when the cooking function is the same or when the amount of ingredients and the cooking function are the same, the compensation time is used entirely to maintain the boiling stage when the cooking appliance performs the preset cooking function, so as to ensure that the food can be fully cooked.

[0036] Optionally,

[0037] When the cooking functions are the same, the control method determines the first cooking time based on the amount of ingredients, wherein the larger the amount of ingredients, the longer the first cooking time; and the smaller the amount of ingredients, the shorter the first cooking time.

[0038] According to this application, the first cooking time is determined based on the amount of ingredients, thereby achieving precise cooking.

[0039] Optionally,

[0040] The amount of ingredients is set by the user; or

[0041] The cooking appliance includes a weighing device, and the amount of ingredients is obtained by weighing using the weighing device.

[0042] According to this application, the method of obtaining the amount of ingredients is flexible.

[0043] Optionally, the control method determines the first cooking time based on the cooking function, and when the cooking functions are the same, the first cooking time is the same.

[0044] According to this application, the first cooking time is determined solely based on the cooking function, thus simplifying the control method.

[0045] Optionally, the cooking appliance includes a timing display device.

[0046] During the cooking process corresponding to the cooking appliance and employing the second cooking procedure, the control method includes:

[0047] During the reserved time period from the moment the user submits the reservation to the moment the cooking appliance begins cooking, the average rate of change of the time displayed on the timing display device is higher than the rate of change of Beijing time, such that at the moment the cooking appliance begins cooking, the time displayed on the timing display device is consistent with the time displayed on the timing display device at the moment the cooking appliance begins cooking when the reserved cooking function is executed according to the first cooking process; and / or

[0048] During the cooking time period from the moment the cooking appliance begins cooking to the moment the cooking appliance just finishes cooking, the average rate of change of the time displayed by the timing display device is lower than the rate of change of Beijing time, so that the time displayed by the timing display device at the moment the cooking appliance just finishes cooking is consistent with the time displayed by the timing display device at the moment the cooking appliance just finishes cooking when the reserved cooking function is performed according to the first cooking process.

[0049] According to this application, when the cooking appliance performs the second cooking process, it automatically extends the cooking time and starts cooking earlier, which is inconsistent with the time set by the user. In order to avoid the user mistakenly thinking that the cooking appliance is malfunctioning, the speed of time change of the display time is adjusted so that the displayed time matches the customer's settings.

[0050] Optionally, the control method includes:

[0051] When the cooking appliance performs the scheduled cooking function, under the condition that the preset conditions are met, the second cooking process is used to carry out the cooking, and the cooking begins at the second cooking time before the scheduled dining time;

[0052] When the cooking appliance performs the scheduled cooking function, if the preset conditions are not met, the first cooking process is used to carry out cooking, and the cooking begins at the moment of the first cooking time before the scheduled dining time.

[0053] According to this application, the anti-overflow device of the cooking appliance is turned off only when the reservation function is executed under specific circumstances, while the anti-overflow device is activated in all other circumstances, which can effectively prevent overflow.

[0054] Optionally, the preset conditions include: the reserved dining time is equal to or later than 21:00, or the reserved dining time is equal to or earlier than 9:00.

[0055] According to this application, when the cooking appliance performs the scheduled cooking function between 9 p.m. and 9 a.m., the anti-overflow device will not work so as not to disturb the user's sleep.

[0056] Optionally, the preset condition also includes: the time for the reserved meal is more than 2 hours away from the time the user submits the reservation.

[0057] According to this application, if the user's reserved dining time is very close, the overflow prevention device will be activated to prevent overflow.

[0058] A second aspect of this application provides a cooking appliance, comprising:

[0059] The cooking space is used to hold the ingredients;

[0060] A heating device for heating the food ingredients;

[0061] A control device, electrically connected to the heating device, is used to control the operation of the heating device;

[0062] An anti-overflow device, electrically connected to the control device, is used to operate under the control of the control device to prevent overflow during the boiling phase of the cooking process;

[0063] An interactive device, electrically connected to the control device, is used to implement a reservation function under the control of the control device; and

[0064] A timing display device, electrically connected to the control device, is used to display the timing time under the control of the control device.

[0065] The control device is configured to control the operation of the cooking appliance according to the control method of any one of the above technical solutions.

[0066] According to this application, when the cooking appliance performs a preset cooking function, the anti-overflow device does not operate, thus preventing noise. To prevent overflow, when the cooking appliance performs a preset cooking function, the power to maintain the boiling phase is reduced, but the cooking time is extended to ensure the food is thoroughly cooked.

[0067] Optionally,

[0068] The cooking appliance also includes a weighing device for weighing the ingredients.

[0069] The control device is electrically connected to the weighing device and determines the first cooking time based on the weight of the food weighed by the weighing device.

[0070] Alternatively, the interactive device may be configured to allow a user to set the amount of ingredients, and the control device may determine the first cooking time based on the amount of ingredients obtained from the interactive device.

[0071] According to this application, the cooking appliance determines the cooking time based on the amount of ingredients in order to implement precise cooking.

[0072] Optionally, the anti-overflow device is an air-cooling device, and the anti-overflow device is installed on the lid of the cooking appliance.

[0073] According to this application, the overflow prevention device is simple to control, has stable performance, and is highly effective. Attached Figure Description

[0094] The following description provides numerous specific details to offer a more thorough understanding of this application. However, it will be apparent to those skilled in the art that this application can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described to avoid confusion with this application.

[0095] To fully understand this application, a detailed description will be provided in the following description. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. Obviously, the implementation of the embodiments of this application is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other embodiments.

[0096] The ordinal numbers such as “first” and “second” used in this application are merely identifiers and have no other meaning, such as a specific order. Furthermore, for example, the term “first component” does not imply the existence of a “second component,” and the term “second component” does not imply the existence of a “first component.” The use of words such as “first,” “second,” and “third” does not indicate any order and can be interpreted as names.

[0097] It should be noted that the terms “upper,” “lower,” “front,” “back,” “left,” “right,” “inner,” “outer,” and similar expressions used in this application are for illustrative purposes only and are not intended to be limiting.

[0098] This application provides a cooking appliance and a control method thereof. The cooking appliance according to this application has a cooking timer function and an anti-overflow device. Preferably, the anti-overflow device is used to prevent overflow during the boiling maintenance phase of the cooking process.

[0099] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0100] like Figure 1 As shown, in a specific embodiment, the cooking appliance 100 according to this application may include a pot body 10 and a lid 20. Typically, a pot inner 11 is provided inside the pot body 10. The pot body 10 may have a cylindrical (or other shaped) storage section, from which the pot inner 11 can be freely placed or removed for easy cleaning. The pot inner 11 is made of metal and constructed as a rotating body with an opening and an inner cavity formed by the pot wall. The capacity of the pot inner 11 is typically less than 6L; for example, the capacity of the pot inner 11 may be 2L or 4L, etc.

[0101] The lid 20 is pivotally connected to the pot body 10 via a pivot shaft for closing the pot body 10. When the lid 20 closes the pot body 10, a cooking space 12 is formed between the lid 20 and the inner pot 11. Understandably, the cooking space 12 is used to hold food. The lid 20 is typically equipped with a steam valve (not shown) and a steam outlet 21, which are connected. Steam in the cooking space 12 enters the steam valve through the steam outlet 21 and is then discharged to the environment through the steam valve.

[0102] The cooking appliance 100 also includes a control device (not shown) for controlling the cooking process. This control device may be, for example, a microcontroller unit (MCU).

[0103] In addition, the cooking appliance 100 may also include a heating element (not shown) and a temperature measuring device (not shown). The heating element (e.g., a heating plate, electromagnetic heating element, etc.) is typically located at the bottom of the pot body 10, below the inner pot 11. The heating element is electrically connected to a control device and is used to heat the inner pot 11 and the food within it under the control of the control device, thereby achieving the cooking function. The temperature measuring device (e.g., a temperature sensor) may be located at the bottom of the pot body 10 and is used to sense the bottom temperature of the pot body 10 (or the inner pot 11). The temperature measuring device is connected to the control device of the cooking appliance 100 to feed back the sensed bottom temperature to the control device, thereby enabling the control device to achieve more precise control of elements such as the heating element based on the temperature information.

[0104] The cooking appliance 100 also includes an interactive device 30 for human-computer interaction. The interactive device 30 may include components such as buttons, knobs, touchscreens, touch displays, and screens. The interactive device 30 is electrically connected to the control device. The cooking appliance 100's timer function is implemented through the interactive device 30.

[0105] like Figure 2 As shown, the cooking appliance 100 also has an anti-overflow device 50. The anti-overflow device 50 is electrically connected to a control device for operation under the control of the control device. The anti-overflow device 50 is, for example, located on the lid 20. The anti-overflow device 50 is configured as a cooling device, including an airflow generator, such as an air pump. The lid 20 is provided with an air outlet 22. The air inlet 51 of the air pump 50 is in communication with the environment, and the air outlet 52 of the air pump 50 is connected to the air outlet 22 via a pipe. When anti-overflow is required (e.g., during the boiling stage of the cooking process), the air pump 50 operates, drawing in low-temperature ambient air through the air inlet 51 and then blowing the low-temperature ambient air into the cooking space 12 through the air outlet 52 and the air outlet 22 to help cool the cooking space 12. Of course, the anti-overflow device 50 can also be constructed as a fan or other forms.

[0106] Preferably, the cooking appliance 100 may further include a weighing device (not shown) for weighing the ingredients. The weighing device, for example, is a pressure sensor, located at the bottom of the pot body 10, below the inner pot 11. When the inner pot 11 is placed in the pot body 10, the inner pot 11 applies pressure to the pressure sensor, and the control device is electrically connected to the pressure sensor, thereby determining the amount of ingredients in the inner pot 11.

[0107] Preferably, the cooking appliance 100 may further include a rice-adding device (not shown) and a water-adding device (not shown), which are electrically connected to a control device. The rice-adding device is used to add solid ingredients to the cooking space 12 under the control of the control device. The water-adding device is used to add water to the cooking space 12 under the control of the control device. For example, when performing a scheduled cooking function, the rice-adding device is used to add solid ingredients corresponding to the amount set by the user to the cooking space 12 at an appropriate time under the control of the control device, and the water-adding device is used to add water corresponding to the amount set by the user to the cooking space 12 at an appropriate time under the control of the control device. Thus, the cooking appliance 100 can add solid ingredients and water to the inner pot 11 only when cooking is required, avoiding the solid ingredients from soaking for too long and spoiling. In such an embodiment, the cooking appliance 100 needs to be equipped with a weighing device and / or a flow control device to ensure that the amount of automatically added ingredients and water is accurate.

[0108] It should be noted that although some structures of the cooking appliance 100 are illustrated here, these examples are merely exemplary and should not be construed as limiting the structure of the cooking appliance 100 in the embodiments of this application.

[0109] like Figure 3 As shown, the control method of the cooking appliance 100 includes two main steps: a cooking preparation step S10 and a cooking execution step S20. It can be understood that the specific steps of the control method of the cooking appliance 100 are executed by the control device of the cooking appliance 100.

[0110] Specifically, in step S10, the control device is configured to design a first cooking process corresponding to the anti-overflow device 50 operating (working during cooking to prevent overflow) and a second cooking process corresponding to the anti-overflow device 50 not operating for each cooking function with an anti-overflow function (hereinafter referred to as cooking function). The first cooking process has a first cooking time t1, and the second cooking process has a second cooking time t2. The heating power of the boiling maintenance phase of the first cooking process is greater than the heating power of the boiling maintenance phase of the second cooking process, and the first cooking time is less than the second cooking time. Examples of cooking functions include steaming rice, cooking porridge, and making soup.

[0111] In step S20, the control device is configured to: when the cooking appliance 100 performs a non-preset cooking function, it employs a first cooking process to perform cooking; when the cooking appliance 100 performs a pre-set cooking function, it employs a second cooking process to perform cooking, and cooking begins at a time Ts before the user-set pre-set dining time Te, which is a second cooking duration t2 (e.g., Figure 4 (As shown). In step S20, the cooking appliance 100 completes the cooking function for a second cooking time t2, thereby providing the user with the cooked food at the scheduled meal time Te.

[0112] Alternatively, in step S20, the control device is configured to: when the cooking appliance 100 performs a non-reserved cooking function, it adopts a first cooking process to perform cooking; when the cooking appliance 100 performs a reserved cooking function, it adopts a second cooking process to perform cooking if preset conditions are met, and starts cooking at a time Ts before the reserved dining time Te, which is the second cooking time t2.

[0113] It is known that the anti-overflow device 50 does not operate during the second cooking process of the cooking appliance 100. To prevent overflow, the heating power is reduced during the boiling stage of the second cooking process, and the cooking time is increased to ensure that the food is fully cooked. Therefore, using the second cooking process in the preset mode can avoid the noise of the anti-overflow device 50 disturbing the user.

[0114] In the first cooking process, the cooking appliance 100 prevents overflow by activating an anti-overflow device. In the second cooking process, the cooking appliance 100 prevents overflow by reducing the heating power used to maintain the boiling phase.

[0115] Preferably, the control device is configured such that when the cooking appliance 100 performs the scheduled cooking function, if the preset conditions are met, the second cooking process is used to perform cooking, and cooking begins at a time Ts before the scheduled dining time Te, which is a second cooking time t2; when the cooking appliance 100 performs the scheduled cooking function, if the preset conditions are not met, the first cooking process is used to perform cooking, and cooking begins at a time To before the scheduled dining time Te, which is a first cooking time t1.

[0116] For example, preset conditions include: the scheduled meal time Te is equal to or later than 21:00, or the scheduled meal time Te is equal to or earlier than 9:00. Understandably, 9:00 PM to 9:00 AM the next day is a period generally used for rest (noise-sensitive period). During this period, the anti-overflow device is deactivated, so that the cooking appliance 100 will not disturb the user's sleep when performing the scheduled cooking function. Of course, to better prevent overflow and shorten cooking time, during noise-insensitive periods, the cooking appliance 100 can use the first cooking process when performing the scheduled cooking function, that is, the anti-overflow device 50 works normally.

[0117] Furthermore, based on determining whether it is a noise-sensitive period, the preset conditions can also include: the reserved dining time Te is more than 2 hours away from the time Tf when the user submitted the reservation. That is, although the reserved dining time Te is in a noise-sensitive period, the reserved dining time Te is no more than 2 hours away from the time Tf when the user submitted the reservation. This means that the user wants to eat in a short time, indicating that the user will not go to bed soon. Therefore, cooking will still be carried out in the first cooking process in this case, so as to better prevent spills.

[0118] Preferably, the duration of the boiling-maintaining phase in the first cooking process is shorter than the duration of the boiling-maintaining phase in the second cooking process. Therefore, in the second cooking process, although the heating power of the heating device decreases during the boiling-maintaining phase, the duration of the boiling-maintaining phase increases, ensuring that the food is fully cooked.

[0119] For example, the second cooking time t2 can be the sum of the first cooking time t1 and the cooking compensation time tc. In some embodiments of this application, the second cooking time t2 can be determined solely based on the first cooking time t1. For example, the cooking compensation time tc is a preset fixed value; regardless of which cooking function the user selects, a fixed cooking compensation time tc is added to the corresponding first cooking time t1 as the second cooking time t2.

[0120] like Figure 4 As shown, the time from the moment the user submits (or confirms) the reservation Tf on the interactive device 30 to the user-set reservation dining time Te is the reservation duration t0. In some embodiments of this application, as the reservation duration increases, the error in the control device's timing becomes larger, easily leading to delays in the completion of cooking. Therefore, preferably, the second cooking duration t2 is determined based on the first cooking duration t1 and the reservation duration t0.

[0121] Specifically, the second cooking time t2 is the sum of the first cooking time t1 and the cooking compensation time tc, wherein the cooking compensation time tc is determined according to the reservation time t0.

[0122] For example, the cooking compensation time tc can be set as follows: the cooking compensation time tc varies depending on the range of the scheduled time t0. That is, different cooking compensation time tc is set for different ranges of scheduled time t0. Specifically, the longer the scheduled time t0, the longer the cooking compensation time tc; the shorter the scheduled time t0, the shorter the cooking compensation time tc. In other words, the greater the timing error, the more severe the delay, and the earlier the cooking begins.

[0123] For example, when the reservation duration t0 is within the first duration range, the cooking compensation duration tc is the first cooking compensation duration tc1; when the reservation duration t0 is greater than the maximum value of the first duration range, the cooking compensation duration tc is greater than the first cooking compensation duration tc1. That is, the cooking compensation duration tc can be simply divided into two levels based on the length of the reservation duration t0.

[0124] Typically, customers can book cooking up to 24 hours in advance. This maximum 24-hour booking period can be divided into three consecutive, distinct time ranges, with a corresponding cooking compensation time tc for each range. Specifically, when the booking time t0 is in the first time range, the cooking compensation time tc is the first cooking compensation time tc1; when t0 is in the second time range, it is the second cooking compensation time tc2; and when t0 is in the third time range, it is the third cooking compensation time tc3. The first, second, and third time ranges are consecutive time intervals. The time value within the first time range is less than the time value within the second time range, the time value within the second time range is less than the time value within the third time range, and the first cooking compensation time tc1 is less than the second cooking compensation time tc2, and the second cooking compensation time tc2 is less than the third cooking compensation time tc3.

[0125] For example, the first cooking time range is [0, 240] minutes (within 4 hours), and the first cooking compensation time tc1 is 4 to 14 minutes (preferably 7 to 11 minutes, for example 9 minutes); the second cooking time range is [240, 1080] minutes (4 to 18 hours), and the second cooking compensation time tc2 is 14 to 24 minutes (preferably 17 to 21 minutes, for example 19 minutes); the third cooking time range is (1080, 1440] minutes (18 to 24 hours), and the third cooking compensation time tc3 is 24 to 34 minutes (preferably 27 to 31 minutes, for example 29 minutes).

[0126] Understandably, for the same cooking function, cooking time is related to the amount of ingredients; the larger the amount of ingredients, the longer the cooking time. Preferably, when the amount of ingredients and the cooking function are the same, the working time of the boiling maintenance phase in the second cooking process is equal to the sum of the working time of the boiling maintenance phase in the first cooking process and the cooking compensation time tc. That is, when the amount of ingredients and the cooking function are the same, the extended cooking time is entirely compensated for in the boiling maintenance phase where the heating power is relatively reduced, to ensure that the ingredients are fully cooked.

[0127] Preferably, when the cooking functions are the same, the control device is configured to determine the first cooking time t1 based on the amount of ingredients. The larger the amount of ingredients, the longer the first cooking time t1; the smaller the amount of ingredients, the shorter the first cooking time t1. The amount of ingredients can be set by the user through the interactive device 30, for example, the user sets the quantity of solid ingredients or the number of diners on the interactive device 30 for the control device to calculate the amount of ingredients. That is, the control device determines the first cooking time t1 based on the amount of ingredients obtained from the interactive device 30. Alternatively, the amount of ingredients can be obtained by weighing with a weighing device. That is, the control device determines the first cooking time based on the weight of the ingredients weighed by the weighing device. The control device, for example, pre-stores the relationship between the amount of ingredients and the cooking time for each cooking function, as well as the cooking curves (e.g., the relationship curves between heating power, heating temperature, and time) for different amounts of ingredients under each cooking function, so that the cooking appliance 100 can accurately perform cooking according to the specific amount of ingredients and cooking function.

[0128] The control device, for example, stores a first cooking curve corresponding to a first cooking process where the anti-overflow device 50 is operating, and a second cooking curve corresponding to a second cooking process where the anti-overflow device 50 is not operating, thereby implementing the first cooking process and the second cooking process according to the first cooking curve and the second cooking curve, respectively. When the amount of ingredients and cooking function are the same, the difference between the first cooking curve and the second cooking curve lies in the heating power and operating time for maintaining the boiling phase. Those skilled in the art can experimentally determine the first cooking curve of the cooking appliance 100, and then modify it to obtain the second cooking curve, without needing to experimentally determine the second cooking curve, thus shortening the development cycle and simplifying the control method.

[0129] In some embodiments of this application, the first cooking time t1 is determined solely based on the cooking function; when the cooking functions are the same, the first cooking time t1 is the same. When the cooking functions are the same, the operating time of the boiling maintenance phase of the second cooking process is equal to the sum of the operating time of the boiling maintenance phase of the first cooking process and the cooking compensation time tc.

[0130] Typically, the cooking appliance 100 includes a timer display device electrically connected to a control device to display a timer, such as a countdown timer, under the control of the control device (the timer display device can be part of the interactive device or set independently of the interactive device). In the case of scheduled cooking, the timer display device will count down to display the remaining time of the scheduled time and / or the remaining cooking time. When the cooking appliance 100 performs a second cooking process, it may automatically extend the cooking time and start cooking earlier, which may be inconsistent with the time set by the user. To avoid the user mistakenly believing that the cooking appliance 100 is malfunctioning, the rate of change of the displayed time is adjusted to match the displayed time with the customer's settings.

[0131] Preferably, during the cooking process corresponding to the second cooking procedure performed by the cooking appliance 100, within the reserved time period from the time Tf when the user submits the reservation to the time Ts when the cooking appliance 100 begins cooking (the time period while waiting for the cooking appliance 100 to start working), Figure 4 (Corresponding to a time period of duration tw), the average rate of change of time vt2 displayed by the timing display device is higher than the rate of change of time vt1 in Beijing time. This ensures that at the moment Ts when the cooking appliance 100 begins cooking, the time displayed by the timing display device is consistent with the time displayed by the timing display device at the moment To when the cooking appliance 100 begins cooking according to the first cooking process (for example, if the first cooking duration t1 is one hour, then the countdown will always show 1:00). For example, if the rate of change of time vt2 is constant, vt2 / vt1 = (tw+tc) / tw. That is, the time used for display is sped up, and the actual duration tw is displayed as (tw+tc) (the timing display device shows that tw+tc has elapsed, but only tw has actually elapsed).

[0132] Preferably, during the cooking process corresponding to the second cooking procedure performed by the cooking appliance 100, the cooking time period (the time period during which the cooking appliance 100 operates) is from the moment Ts when cooking begins to the moment Te when cooking just ends. Figure 4 (Corresponding to a time period of duration t2), the average rate of change of time vt3 displayed by the timing display device is lower than the rate of change of time vt1 in Beijing time. This ensures that at the moment Te when the cooking appliance 100 has just finished cooking, the time displayed by the timing display device is consistent with the time displayed by the timing display device at the moment Te when the cooking appliance 100 has just finished cooking according to the first cooking process (e.g., both countdowns are 0:00). For example, if the rate of change of time vt3 is constant, vt3 / vt1 = t1 / t2. That is, the time used for display is slowed down, and the actual duration t2 is displayed as duration t1 (the timing display device shows that duration t1 has elapsed, but the actual duration t2 has elapsed).

[0133] The following combination Figure 4 and Figure 5 This describes the process by which cooking appliance 100 executes the scheduled cooking function using the second cooking process. In the following examples, for the sake of brevity, the impact of ingredient quantity on cooking time is not considered; the first cooking compensation time tc1 is, for example, 9 minutes, the second cooking compensation time tc2 is, for example, 19 minutes, and the third cooking compensation time tc3 is, for example, 29 minutes; the first cooking time t1 corresponding to the user's scheduled cooking function is, for example, 60 minutes.

[0134] Example 1

[0135] The user submits the reservation at 15:00 (Tf) and the reserved dining time is 18:00 (Te).

[0136] Based on Tf and Te, the reservation duration t0 is 180 minutes, which falls within the first duration range. Therefore, the cooking compensation duration tc is taken as the value of the first cooking compensation duration tc1. Thus:

[0137] The second cooking time t2 = t1 + tc1 = 60 + 9 = 69 minutes.

[0138] The waiting time tw = t0 - t2 = 180 - 69 = 111 minutes.

[0139] Thus, cooking appliance 100 begins cooking at 69 minutes before the scheduled dining time Te (16:51), that is, at the moment after the reservation submission time Tf and the waiting time tw (111 minutes). At 16:51, the timer displays 60 minutes remaining.

[0140] When the time reaches Ts (16:51), cooking appliance 100 starts working and completes cooking in the second cooking time t2 (69 minutes). When cooking is completed at 18:00, the timer display shows 0 remaining time.

[0141] Example 2

[0142] The user submits the reservation at 12:00 (Tf) and the reserved dining time is 18:00 (Te).

[0143] Based on Tf and Te, the reservation duration t0 is 360 minutes, which falls within the second duration range. Therefore, the cooking compensation duration tc is taken as the value of the second cooking compensation duration tc2. Thus:

[0144] The second cooking time t2 = t1 + tc2 = 60 + 19 = 79 minutes.

[0145] The waiting time tw = t0 - t2 = 360 - 79 = 281 minutes.

[0146] Thus, cooking appliance 100 begins cooking at 79 minutes before the scheduled dining time Te (16:41), that is, at the moment after the reservation submission time Tf and the waiting time tw (281 minutes). At 16:41, the timer displays 60 minutes remaining.

[0147] When the time reaches Ts (16:41), cooking appliance 100 starts working and completes cooking in the second cooking time t2 (79 minutes). When cooking is completed at 18:00, the timer display shows 0 remaining time.

[0148] Example 3

[0149] The user submits the reservation at 12:00 (Tf), and the reserved dining time is 8:00 the next day (Te).

[0150] Based on Tf and Te, the reservation duration t0 is 1200 minutes, which falls within the third duration range. Therefore, the cooking compensation duration tc is taken as the value of the third cooking compensation duration tc3. Thus:

[0151] The second cooking time t2 = t1 + tc3 = 60 + 29 = 89 minutes.

[0152] The waiting time tw = t0 - t2 = 1200 - 89 = 1111 minutes.

[0153] Thus, cooking appliance 100 begins cooking at time Ts (6:31 the next day), 89 minutes before the scheduled dining time Te, that is, at the time tw (1111 minutes) after the reservation submission time Tf. At 6:31 the next day, the timer displays 60 minutes remaining.

[0154] When the time reaches Ts (6:31 the next day), cooking appliance 100 starts working and completes cooking in the second cooking time t2 (89 minutes). When cooking is completed at 8:00 the next day, the timer display shows 0 remaining time.

[0155] In the example above, all timing is performed by the timer of the cooking appliance 100, which may be configured as part of the control device.
