Description

Technical Field

[0001] The present application relates to the technical field of cooking appliances, and in particular to a cooking appliance control method and a cooking appliance using the control method. Background Art

[0002] Some cooking appliances have a reservation function, so that users can reserve meal times in advance, and the cooking appliances will automatically cook at the appropriate time and provide food for users at the preset meal time. Usually, users reserve breakfast for the next day in the evening. The cooking appliance will turn on the fan when working to prevent overflow. The fan will make a certain sound when working, and it happens to be morning, and the noise will affect the user's sleep.

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

[0004] A series of simplified concepts are introduced in the Summary of the Invention section, which will be further described in detail in the Detailed Description of the Invention section. The Summary of the Invention section of this application does not mean to attempt to define the key features and essential technical features of the claimed technical solution, nor does it mean to attempt to determine the scope of protection of the claimed technical solution.

[0005] In order to at least partially solve the above problems, a first aspect of the present application provides a control method for a cooking appliance, wherein the cooking appliance has a reservation function and an overflow prevention device, wherein the overflow prevention device is used to work in the boiling maintenance stage of the cooking process to prevent overflow, and wherein the control method comprises:

[0006] For each cooking function with an overflow prevention function, a first cooking process corresponding to the overflow prevention device working and a second cooking process corresponding to the overflow prevention device not working are designed, wherein 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 stage of the first cooking process is greater than the heating power of the boiling maintenance stage 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 perform cooking.

[0008] When the cooking appliance performs the scheduled cooking function, the second cooking process is used to implement cooking, and the cooking is started at the second operation time before the scheduled meal time; or, when the cooking appliance performs the scheduled cooking function, the second cooking process is used to implement cooking if a preset condition is met, and the cooking is started at the second operation time before the scheduled meal time,

[0009] Wherein, the second operation time is greater than the second cooking time.

[0010] According to the present application, when the cooking appliance performs the scheduled cooking function, the overflow prevention device does not work, so no noise is generated. In order to prevent overflow, when the cooking appliance performs the scheduled cooking function, the power of the boiling stage is reduced, but at the same time, the cooking time is extended on the basis of the cooking time when the corresponding overflow prevention device is working, so as to ensure that the food is fully cooked. At the same time, since the error of the timer will cause delays and the cooking end is delayed, cooking is also performed in advance to a certain extent to ensure that the user gets the meal at the scheduled time.

[0011] Optionally, the working time of the boiling maintenance phase of the first cooking process is shorter than the working time of the boiling maintenance phase of the second cooking process.

[0012] According to the present application, when the overflow prevention device is not working, the power of maintaining the boiling stage is reduced, and the working time of maintaining the boiling stage is correspondingly extended, so that the food is fully cooked.

[0013] Optionally, the second cooking time is the sum of the first cooking time and the first compensation time.

[0014] According to the present application, the method for determining the second cooking time is simple.

[0015] The duration from the time when the user submits the reservation to the reserved dining time set by the user is the reservation duration, and the first compensation duration is determined according to the reservation duration; or

[0016] Or the first compensation duration is a preset fixed value.

[0018] Optionally,

[0019] The first compensation duration is determined according to the reservation duration. When the reservation duration is within different duration ranges, the first compensation duration is different.

[0020] The longer the reservation duration is, the longer the first compensation duration is; the shorter the reservation duration is, the shorter the first compensation duration is.

[0021] According to the present application, as the reservation time becomes longer, the available reservation waiting time becomes longer, so that the second cooking time can be extended to allow the food to be fully cooked.

[0022] Optionally,

[0023] When the reservation duration is within the first duration range, the first compensation duration is a first cooking compensation duration;

[0024] When the reservation duration is greater than the maximum value of the first duration range, the first compensation duration is greater than the first cooking compensation duration.

[0025] further,

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

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

[0028] When the reservation duration is within the third duration range, the first compensation duration is the third cooking compensation duration;

[0029] Among them, 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 smaller than the time value in the second time range, the time value in the second time range is smaller than the time value in the third time range, the first cooking compensation time is smaller than the second cooking compensation time, and the second cooking compensation time is smaller than the third cooking compensation time.

[0030] further,

[0031] The first duration ranges from [0, 240) minutes, and the first cooking compensation duration ranges from 4 to 14 minutes;

[0032] The second duration ranges from [240, 1080] minutes, and the second cooking compensation duration ranges from 14 to 24 minutes;

[0033] The third duration range is (1080, 1440] minutes, and the third cooking compensation duration is 24 to 34 minutes.

[0034] According to the present application, the method for determining the first compensation duration is simple.

[0035] Optionally, when the cooking functions are the same or when the amount of ingredients and the cooking function 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 first compensation time.

[0036] According to the present application, when the cooking function is the same or the amount of ingredients and the cooking function are the same, when the cooking appliance performs the scheduled cooking function, the compensation time is fully used to maintain the boiling stage to ensure that the food can be fully cooked.

[0037] Optionally, when the cooking functions are the same, the first cooking time is determined according to the amount of ingredients.

[0038] Among them, the larger the amount of the food, the longer the first cooking time; the smaller the amount of the food, the shorter the first cooking time.

[0039] According to the present application, the first cooking time is determined according to the amount of ingredients, thereby achieving precise cooking.

[0040] Optionally,

[0041] The amount of ingredients is set by the user; or

[0042] The cooking appliance comprises a weighing device, and the amount of the food is obtained by weighing the weighing device.

[0043] According to the present application, the method of obtaining the amount of ingredients is flexible.

[0044] Optionally, the first cooking time is determined according to the cooking function, and when the cooking functions are the same, the first cooking time is the same.

[0045] According to the present application, the method for the cooking appliance to determine the first cooking time is simple.

[0046] Optionally, the second operation time is the sum of the second cooking time and the second compensation time.

[0047] According to the present application, the method for determining the second operation duration is simple.

[0048] Optionally, the duration from the time when the user submits the reservation to the reserved dining time set by the user is the reservation duration.

[0049] The longer the reservation duration is, the longer the second compensation duration is; the shorter the reservation duration is, the shorter the second compensation duration is.

[0050] According to the present application, the longer the reservation time is, the greater the accumulated error of the timer is, and thus the earlier the cooking needs to be done.

[0051] Optionally, every time the reservation duration increases by a first preset duration, the second compensation duration increases by a second preset duration.

[0052] Furthermore, when the reservation duration is less than the first preset duration, the second compensation duration is 0.

[0053] According to the present application, the second compensation time duration is an increasing arithmetic progression along with the linear increase of the reservation time duration, and the method for determining the second compensation time duration is simple.

[0054] Optionally,

[0055] The first preset duration is 120 to 240 minutes; and / or

[0056] The second preset time length is 1 to 3 minutes.

[0057] According to the present application, the calculation parameters of the second compensation duration are reasonable.

[0058] Optionally, the control method includes:

[0059] When the cooking appliance performs the scheduled cooking function, if the preset conditions are met, the second cooking process is used to perform cooking, and the cooking is started at the time of the second operation time before the scheduled meal time;

[0060] When the cooking appliance executes the scheduled cooking function, if the preset condition is not met, cooking is implemented using the first cooking process, and cooking is started at the moment of the first cooking duration before the scheduled meal time, or cooking is started at the moment of the first operation duration before the scheduled meal time, wherein the first operation duration is the sum of the first cooking duration and the second compensation duration.

[0061] According to the present application, the cooking appliance turns off the overflow prevention device only when executing the reservation function under specific circumstances, and enables the overflow prevention device to work in other circumstances, thereby effectively preventing overflow.

[0062] Optionally, the preset condition includes: 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.

[0063] According to the present application, when the cooking appliance performs a scheduled cooking function between 9 pm and 9 am, the overflow prevention device does not work to avoid disturbing the user's sleep.

[0064] Optionally, the preset condition also includes: the reserved dining time is more than 2 hours from the time when the user submits the reservation.

[0065] According to the present application, if the dining time reserved by the user is very close, the overflow prevention device is operated to prevent overflow.

[0066] A second aspect of the present application provides a cooking utensil, characterized in that it comprises:

[0073] According to the present application, when the cooking appliance performs the scheduled cooking function, the overflow prevention device does not work, so no noise is generated. In order to prevent overflow, when the cooking appliance performs the scheduled cooking function, the power of the boiling stage is reduced, but at the same time, the cooking time is extended on the basis of the cooking time when the corresponding overflow prevention device is working, so as to ensure that the food is fully cooked. At the same time, since the error of the timer will cause delays and the cooking end is delayed, cooking is also performed in advance to a certain extent to ensure that the user gets the meal at the scheduled time.

[0074] Optionally,

[0075] The cooking appliance further comprises a weighing device for weighing the food material.

[0103] In the following description, a large number of specific details are provided to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present application, some technical features well known in the art are not described.

[0104] In order to thoroughly understand the present application, a detailed description will be provided in the following description. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. Obviously, the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other embodiments.

[0105] Ordinal numbers such as "first" and "second" cited in this application are merely identifiers and do not have any other meaning, such as a specific order, etc. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component". The use of the words "first", "second", and "third" does not indicate any order, and these words can be interpreted as names.

[0106] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this application are for illustrative purposes only and are not limiting.

[0107] The present application provides a cooking appliance and a control method thereof. The cooking appliance according to the present application has a cooking reservation function and an overflow prevention device. Preferably, the overflow prevention device is used to work in the boiling maintenance stage of the cooking process to prevent overflow.

[0108] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0109] like Figure 1 As shown, in a specific embodiment, the cooking utensil 100 according to the present application may include a pot body 10 and a cover body 20. Usually, a pot body 11 is arranged in the pot body 10. The pot body 10 may have a storage portion in a cylindrical shape (or other shapes), and the pot body 11 can be freely placed in the storage portion or taken out from the storage portion to facilitate the cleaning of the pot body 11. The pot body 11 is made of a metal material and is constructed as a rotating body with an opening and an inner cavity formed by a pot wall. The capacity of the pot body 11 is usually less than 6L, for example, the capacity of the pot body 11 can be 2L or 4L.

[0110] The cover 20 can be pivotally connected to the pot body 10 via a pivot shaft, and is used to cover the pot body 10. When the cover 20 covers the pot body 10, a cooking space 12 is formed between the cover 20 and the pot body 11. It can be understood that the cooking space 12 is used to hold food. The cover 20 is usually provided with a steam valve (not shown) and a steam outlet 21, and the steam valve is connected to the steam outlet 21. The 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.

[0111] The cooking appliance 100 further includes a control device (not shown) for implementing cooking control of the cooking appliance 100. The control device may be, for example, a microprocessing unit (MCU).

[0112] In addition, the cooking utensil 100 may also have a heating device (not shown) and a temperature measuring device (not shown). The heating device (such as a heating plate, an electromagnetic heating component, etc.) is usually arranged at the bottom of the pot body 10, below the inner pot 11. The heating device is electrically connected to the control device, and is used to heat the inner pot 11 and the ingredients therein under the control of the control device, thereby realizing the cooking function. The temperature measuring device (such as a temperature sensor) can be arranged 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 utensil 100 to feed back the sensed bottom temperature to the control device, so that the control device can achieve more accurate control of, for example, the heating device based on the temperature information.

[0113] The cooking appliance 100 also has an interactive device 30 for realizing a human-computer interaction function. The interactive device 30 may include, for example, buttons, knobs, touch-membrane keys, a touch screen, a display screen, and other components. The interactive device 30 is electrically connected to the control device. The reservation function of the cooking appliance 100 is realized through the interactive device 30.

[0114] The cooking appliance 100 includes a timer for timing, such as timing the cooking time, timing the reservation time, etc. The timer is usually a part of the control device. Usually, the cooking appliance 100 also includes a timing display device, which is electrically connected to the control device (timer) to display timing under the control of the control device, such as countdown (the timing display device can be a part of the interactive device 30, or can be set independently of the interactive device 30). In the case of scheduled cooking, the timing display device will count down and display the remaining reservation time and / or the remaining cooking time.

[0115] like Figure 2As shown, the cooking appliance 100 also has an anti-overflow device 50. The anti-overflow device 50 is electrically connected to the control device and is used to work under the control of the control device. The anti-overflow device 50 is, for example, arranged on the cover body 20. The anti-overflow device 50 is, for example, configured as an air cooling device, including an air flow generating device, such as an air pump. The cover body 20 is provided with an air blowing port 22. The air inlet 51 of the air pump 50 is connected to the environment, and the air outlet 52 of the air pump 50 is connected to the air blowing port 22 through a pipeline. When anti-overflow is required (for example, in the boiling maintenance stage of the cooking process), the air pump 50 works, sucks in low-temperature air from the environment through the air inlet 51, and then blows the low-temperature air from the environment into the cooking space 12 through the air outlet 52 and the air blowing port 22 to help cool down the cooking space 12. Of course, the anti-overflow device 50 can also be constructed as a fan or other forms.

[0116] Preferably, the cooking appliance 100 may further include a weighing device (not shown) for weighing the weight of the food. The weighing device is, for example, a pressure sensor, which is disposed at the bottom of the pot body 10 and 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, so that the amount of food in the inner pot 11 can be known.

[0117] Preferably, the cooking appliance 100 may further include a rice adding device (not shown) and a water adding device (not shown), and the rice adding device and the water adding device are electrically connected to the control device. The rice adding device is used to add solid food 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 the scheduled cooking function, the rice adding device is used to add solid food corresponding to the amount of food 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 of food 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 food and water to the pot 11 when cooking is required to be performed, so as to avoid the solid food from being soaked for too long and deteriorating. In such an embodiment, the cooking appliance 100 needs to be provided with a weighing device and / or a flow control device to enable the automatic addition of food and water to be accurate.

[0118] It should be noted that although part of the structure of the cooking appliance 100 is schematically described at this point, these examples are merely exemplary and cannot be used as a limitation on the structure of the cooking appliance 100 of the embodiment of the present application.

[0119] like Figure 3 As shown, the control method of the cooking appliance 100 includes two major steps, a cooking preparation step S10 and a cooking execution step S20. It can be understood that the steps of the control method of the cooking appliance 100 are specifically executed by the control device of the cooking appliance 100.

[0120] Specifically, in step S10, the control device is configured to design a first cooking process corresponding to the anti-overflow device 50 being engaged in operation (working to prevent overflow during the cooking process) and a second cooking process corresponding to the anti-overflow device 50 not being operated for each cooking function with an anti-overflow function (hereinafter referred to as a cooking function), wherein the first cooking process has a first cooking time t1, the second cooking process has a second cooking time t2, the heating power of the first cooking process in the boiling maintenance stage is greater than the heating power of the second cooking process in the boiling maintenance stage, and the first cooking time is less than the second cooking time. The cooking functions are, for example, steaming rice, cooking porridge, and making soup.

[0121] In step S20, the control device is configured to: when the cooking appliance 100 performs a non-scheduled cooking function, use the first cooking process to implement cooking; when the cooking appliance 100 performs a scheduled cooking function, use the second cooking process to implement cooking, and start cooking at the time Ts of the second operation time length to2 before the scheduled dining time Te set by the user (such as Figure 4 As shown), the second operation time to2 is greater than the second cooking time t2. In step S20, the cooking appliance 100 takes into account the accumulated error of the timer, and in order to avoid delay in cooking, the cooking appliance 100 starts cooking at a time Ts earlier than a time Tt of the second cooking time t2 (the time taken to perform the cooking function) before the scheduled meal time Te, thereby providing the user with cooked food at a time Tr no later than the scheduled meal time Te (a time Tr is a time after the second cooking time t2 after the time Ts).

[0122] It can be seen that the overflow prevention device 50 does not work in the second cooking process of the cooking appliance 100. In order to prevent overflow, the second cooking process reduces the heating power in the boiling stage to ensure that the food is fully cooked and the cooking time is increased. Therefore, when cooking food in the second cooking process in the reservation mode, the noise of the overflow prevention device 50 can be avoided from disturbing the user.

[0123] In the first cooking process, the cooking appliance 100 prevents overflow by operating the overflow prevention device. In the second cooking process, the cooking appliance 100 prevents overflow by reducing the heating power to maintain the boiling stage.

[0124] Alternatively, in step S20, the control device is configured as follows: when the cooking appliance 100 performs a non-reserved cooking function, cooking is implemented using a first cooking process; when the cooking appliance 100 performs a reserved cooking function, cooking is implemented using a second cooking process if preset conditions are met, and cooking begins at a time Ts of the second operation duration to2 before the reserved meal time Te.

[0125] For example, the 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. It can be understood that 9:00 pm to 9:00 am the next day is a period commonly used for rest (noise-sensitive period). During this period, the overflow prevention device stops working, so that the cooking appliance 100 will not disturb the user's sleep when performing the scheduled cooking function. Of course, in order to better prevent overflow and shorten cooking time, during the noise-insensitive period, the cooking appliance 100 can use the first cooking process when performing the scheduled cooking function, that is, the overflow prevention device 50 works normally.

[0126] Furthermore, based on determining whether it is a noise-sensitive period, the preset condition may also include: the scheduled dining time Te is more than 2 hours away from the time Tf when the user submits the reservation. That is, although the scheduled dining time Te is in the noise-sensitive period, the scheduled dining time Te is no more than 2 hours away from the time Tf when the user submits the reservation, which means that the user wants to eat in a short time, indicating that the user will not go to bed soon, so at this time, cooking will also be performed in the first cooking process, so as to better prevent overflow.

[0127] Preferably, the working time of the boiling maintenance stage of the first cooking process is shorter than the working time of the boiling maintenance stage of the second cooking process. Thus, in the second cooking process, although the heating power of the heating device in the boiling maintenance stage decreases, the working time of the boiling maintenance stage increases, which can ensure that the food is fully cooked.

[0128] like Figure 4 As shown, the time from the moment Tf when the user submits (or confirms) the reservation on the interactive device 30 to the reserved dining time Te set by the user is the reservation time t0. As the reservation time becomes longer, the error of the control device controlling the time becomes larger and larger, and the cooking end is prone to delay. Therefore, preferably, the second cooking time t2 is determined according to the first cooking time t1 and the reservation time t0.

[0129] Specifically, the second cooking time t2 is the sum of the first cooking time t1 and the first compensation time tk1.

[0130] The first compensation time tk1 may be a preset fixed value. No matter which cooking function the user selects, the first compensation time tk1 is fixedly added to the corresponding first cooking time t1 as the second cooking time t2.

[0131] Alternatively, the first compensation time tk1 can also be determined according to the reservation time t0. For example, when the reservation time t0 is in different time ranges, the first compensation time tk1 is different. That is, different first compensation time tk1 is set corresponding to different time ranges of the reservation time t0. The longer the reservation time t0 is, the longer the first compensation time tk1 is; the shorter the reservation time t0 is, the longer the first compensation time tk1 is. That is, the greater the timing error is, the more serious the delay is, and the earlier the cooking should be started.

[0132] For example, when the reservation time t0 is within the first time range, the first compensation time tk1 is the first cooking compensation time tc1; when the reservation time t0 is greater than the maximum value of the first time range, the first compensation time tk1 is greater than the first cooking compensation time tc1. That is, the first cooking compensation time tc1 can be simply divided into two levels according to the length of the reservation time t0.

[0133] Usually, the customer can make a cooking reservation up to 24 hours in advance. The 24-hour reservation time can be divided into three continuous and different time ranges, and a first compensation time tk1 is set for each time range. That is, when the reservation time t0 is in the first time range, the first compensation time tk1 is the first cooking compensation time tc1; when the reservation time t0 is in the second time range, the first compensation time tk1 is the second cooking compensation time tc2; when the reservation time t0 is in the third time range, the first compensation time tk1 is the third cooking compensation time tc3. Among them, the first time range, the second time range and the third time range are continuous time ranges, 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 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.

[0134] For example, the first duration 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 duration 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 duration 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).

[0135] As mentioned above, in consideration of the timing error of the timer, the second operation time to2 should be greater than the second cooking time t2. For example, the second operation time to2 is the sum of the second cooking time t2 and the second compensation time tk2. The longer the reservation time t0 is, the greater the cumulative error of the timer is. Therefore, preferably, the longer the reservation time t0 is, the longer the second compensation time tk2 is (that is, the earlier the cooking needs to be started); the shorter the reservation time t0 is, the shorter the second compensation time tk2 is.

[0136] For example, the second compensation duration tk2 can be set in such a way that for every increase of the first preset duration tp1 in the reservation duration t0, the second compensation duration tk2 increases by a second preset duration tp2. When the reservation duration t0 is less than the first preset duration tp1, the second compensation duration tk2 is 0. Thus, the longer the reservation duration t0, the longer the second compensation duration tk2; the shorter the reservation duration t0, the shorter the second compensation duration tk2. With the linear growth of the reservation duration t0, the second compensation duration tk2 presents an arithmetic progression with gradually increasing values. Preferably, the first preset duration tp1 is 120 to 240 minutes, for example, 180 minutes. Preferably, the second preset duration tp2 is 1 to 4 minutes, for example, 1 minute.

[0137] It can be understood that the present application is equivalent to dividing the reservation duration t0 into several duration intervals corresponding to the second compensation duration tk2, and the second compensation duration tk2 has a value corresponding to each duration interval. For example, the first duration interval is [0, tp1), and the second compensation duration tk2 corresponding to the first duration interval is 0; the second duration interval is [tp1, 2×tp1), and the second compensation duration tk2 corresponding to the second duration interval is tp2; the third duration interval is [2×tp1, 3×tp1), and the second compensation duration tk2 corresponding to the third duration interval is 2×tp2; and so on. The difference from the first compensation duration tk1 is that the division of the duration intervals corresponding to the first compensation duration tk1 is non-uniform, while the division of the duration intervals corresponding to the second compensation duration tk2 is uniform; the increase of the first compensation duration tk1 can be non-arithmetic (or arithmetic), while the increase of the second compensation duration tk2 must be arithmetic; the number of duration intervals corresponding to the second compensation duration tk2 (for example, 6 to 12) is more than the number of duration intervals corresponding to the second compensation duration tk2.

[0138] Alternatively, the second compensation time tk2 can be designed to be completely positively correlated with the reservation time t0 and change with the change of the reservation time t0. For example, the second compensation time tk2 is the quotient of the reservation time t0 divided by the first preset time tp1, that is, the second compensation time tk2 is proportional to the reservation time t0.

[0139] It can be understood that for the same cooking function, the 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 stage of the second cooking process is equal to the sum of the working time of the boiling maintenance stage of the first cooking process and the first compensation time tk1. That is, when the amount of ingredients and the cooking function are the same, the extended cooking time is fully compensated in the boiling maintenance stage with relatively reduced heating power to ensure that the ingredients are fully cooked.

[0140] Preferably, when the cooking functions are the same, the control device is configured to determine the first cooking time t1 according to the amount of ingredients. The larger the amount of ingredients, the longer the first cooking time t1; the smaller the amount of ingredients, the smaller 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 number of solid ingredients or the number of diners in 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 according to the amount of ingredients obtained from the interactive device 30. Alternatively, the amount of ingredients can be obtained by weighing by a weighing device. That is, the control device determines the first cooking time according to 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 under each cooking function, as well as the cooking curves of different amounts of ingredients under each cooking function (such as the relationship curve between heating power, heating temperature and time), so that the cooking appliance 100 can accurately implement cooking according to the specific amount of ingredients and cooking functions.

[0141] The control device, for example, stores a first cooking curve corresponding to a first cooking process in which the overflow prevention device 50 is working, and a second cooking curve corresponding to a second cooking process in which the overflow prevention device 50 is not working, so that the first cooking process and the second cooking process are implemented according to the first cooking curve and the second cooking curve, respectively. When the amount of ingredients and the cooking function are the same, the difference between the first cooking curve and the second cooking curve is the heating power and working time for maintaining the boiling stage. Those skilled in the art can determine the first cooking curve of the cooking utensil 100 through experiments, and then correct the first cooking curve to obtain the second cooking curve without having to determine the second cooking curve through experiments, thereby shortening the development cycle and simplifying the control method.

[0142] In some embodiments of the present application, the first cooking time t1 is determined only according to the cooking function, and when the cooking functions are the same, the first cooking time t1 is the same. When the cooking functions are the same, the working time of the boiling maintenance stage of the second cooking process is equal to the sum of the working time of the boiling maintenance stage of the first cooking process and the first compensation time tk1.

[0143] Preferably, the control device is configured such that, when the cooking appliance 100 performs the scheduled cooking function, if the aforementioned preset conditions are met, cooking is implemented using the second cooking process, and cooking starts at time Ts which is the second operation duration to2 before the scheduled meal time Te; when the cooking appliance 100 performs the scheduled cooking function, if the preset conditions are not met, cooking is implemented using the first cooking process, and cooking starts at time To which is the first cooking duration t1 before the scheduled meal time Te, or cooking starts at time Tt which is the first operation duration to1 before the scheduled meal time Te, wherein the first operation duration to1 is the sum of the first cooking duration t1 and the second compensation duration tk2.

[0144] That is, when the aforementioned preset conditions are not met (for example, the scheduled meal time Te is not in a noise-sensitive period, so there is no need to consider noise interference), the cooking appliance 100 uses the first cooking process to perform the scheduled cooking function, so that overflow can be better prevented. In this case, the cooking appliance 100 can consider the timer error and cook in advance so that the user can get the meal no later than the scheduled meal time Te.

[0145] The following combination Figure 4 and Figure 5 The process of the cooking appliance 100 using the second cooking process to perform the scheduled cooking function is introduced. In the following examples, for the purpose of concise description, the influence of the amount of ingredients on the 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 cooking function scheduled by the user is, for example, 60 minutes; the first preset time tp1 is, for example, 180 minutes, and the second preset time tp2 is, for example, 1 minute.

[0146] Example 1

[0147] The time Tf when the user submits the reservation is 15:00, and the reserved dining time Te is 18:00.

[0148] According to Tf and Te, it can be known that the reservation time t0 is 180 minutes, which belongs to the first time range, the first compensation time tk1 takes the value of the first cooking compensation time tc1, and the second compensation time tk2 is a second preset time tp2 (the reservation time t0 includes a first preset time tp1), which is 1 minute. Therefore:

[0149] The second cooking time is t2 = t1 + tc1 = 60 + 9 = 69 minutes,

[0150] The second operation duration to2=t2+tk2=69+1=70 minutes.

[0151] Waiting time tw = t0 - t2 - tk2 = 180 - 69 - 1 = 110 minutes.

[0152] Therefore, the cooking appliance 100 starts cooking at time Ts (16:50) 70 minutes before the reserved meal time Te, that is, starts cooking at a time after the waiting time tw (110 minutes) after the reservation submission time Tf.

[0153] When the time reaches the time Ts (16:50), the cooking appliance 100 is operated, and the cooking is completed in the second cooking time t2 (69 minutes).

[0154] Example 2

[0155] The time Tf when the user submits the reservation is 12:00, and the reserved dining time Te is 18:00.

[0156] According to Tf and Te, it can be known that the reservation time t0 is 360 minutes, which belongs to the second time range, the first compensation time tk1 takes the value of the second cooking compensation time tc2, and the second compensation time tk2 is two second preset time tp2 (the reservation time t0 includes two first preset time tp1), which is 2 minutes. Therefore:

[0157] The second cooking time t2 = t1 + tc2 = 60 + 19 = 79 minutes,

[0158] The second operation duration to2=t2+tk2=79+2=81 minutes.

[0159] Waiting time tw=t0-t2-tk2=360-79-2=279 minutes.

[0160] Therefore, the cooking appliance 100 starts cooking at time Ts (16:39), 81 minutes before the reserved meal time Te, that is, starts cooking at a time after the waiting time tw (279 minutes) after the reservation submission time Tf.

[0161] When the time reaches the time Ts (16:39), the cooking appliance 100 is operated, and the cooking is completed in the second cooking time t2 (79 minutes).

[0162] Example 3

[0163] The time Tf when the user submits the reservation is 12:00, and the reserved dining time Te is 8:00 the next day.

[0164] According to Tf and Te, it can be known that the reservation time t0 is 1200 minutes, which belongs to the third time range, the first compensation time tk1 takes the value of the third cooking compensation time tc3, and the second compensation time tk2 is six second preset time tp2 (the reservation time t0 includes six first preset time tp1), which is 6 minutes. Therefore:

[0165] The second cooking time t2 = t1 + tc3 = 60 + 29 = 89 minutes,

[0166] The second operation duration to2=t2+tk2=89+6=95 minutes.

[0167] Waiting time tw = t0 - t2 - tk2 = 1200 - 89 - 6 = 1105 minutes.

[0168] Therefore, the cooking appliance 100 starts cooking at time Ts (6:25 the next day), 89 minutes before the reserved meal time Te, that is, starts cooking at the time after the waiting time tw (1105 minutes) after the reservation submission time Tf.

[0169] When the time reaches the time Ts (6:25 the next day), the cooking appliance 100 is operated, and the cooking is completed in the second cooking time t2 (89 minutes).

[0170] In the above examples, all timing operations are performed by a timer of the cooking appliance 100 , which may be configured as a part of the control device, for example.
