Description

TECHNICAL FIELD

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

[0002] Some cooking appliances have a reservation function, which allows users to reserve a meal time in advance. The cooking appliance will automatically execute cooking at the appropriate time to provide food for the user at the preset meal time. Usually, the user reserves breakfast for the next day in the evening. The cooking appliance will turn on the air pump to prevent overflow during working hours. The air pump will make some noise, which will affect the user's sleep at this time in the morning.

[0003] Therefore, there is a need for a cooking appliance to at least partially solve the above problems. SUMMARY

[0004] A series of simplified concepts are introduced in the summary section, which will be further described in detail in the detailed description section. The summary section of the present application does not mean to attempt to limit the key features and essential technical features of the claimed technical solutions, nor to attempt to determine the protection scope of the claimed technical solutions.

[0010] According to the present application, the anti-overflow device does not work when the cooking appliance performs the pre-ordered cooking function, so that no noise is generated. In order to prevent overflow, the cooking appliance maintains the power reduction during the boiling stage when performing the pre-ordered cooking function, but at the same time, the cooking time is extended on the basis of the cooking time when the corresponding anti-overflow device works, so as to ensure that the food is fully cooked. At the same time, due to the error of the timer, the delay time appears, and the cooking end delay phenomenon appears, so the cooking is also advanced to a certain extent to ensure that the user obtains the meal at the pre-ordered time.

[0011] Optionally, the working duration of the maintaining boiling stage of the first cooking process is less than the working duration of the maintaining boiling stage of the second cooking process.

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

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

[0015] The duration from the time when the user submits the pre-order to the pre-ordered meal time set by the user is the pre-order duration, and the first compensation duration is determined according to the pre-order duration; or

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

[0025] Further,

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

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

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

[0029] The first duration range, the second duration range and the third duration range are continuous duration intervals, a value of a duration in the first duration range is less than a value of a duration in the second duration range, the value of the duration in the second duration range is less than a value of a duration in the third duration range, the first cooking compensation duration is less than the second cooking compensation duration, and the second cooking compensation duration is less than the third cooking compensation duration.

[0032] The second duration range is [240, 1080] minutes, and the second cooking compensation duration is 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 determination method of the first compensation duration is simple.

[0035] Optionally, in the case that the cooking function is the same or in the case that the food material amount and the cooking function are the same, the working duration of the maintaining boiling stage of the second cooking process is equal to the sum of the working duration of the maintaining boiling stage of the first cooking process and the first compensation duration.

[0036] According to the present application, in the case that the cooking function is the same or in the case that the food material amount and the cooking function are the same, when the cooking appliance performs the reservation cooking function, the compensation duration is completely used for the maintaining boiling stage, so as to ensure that the food can be fully cooked.

[0037] Optionally, in the case that the cooking function is the same, the first cooking duration is determined according to the food material amount,

[0038] The greater the quantity of the food material is, the longer the first cooking duration is; the smaller the quantity of the food material is, the shorter the first cooking duration is.

[0039] According to the present application, the first cooking duration is determined according to the quantity of the food material, so as to realize precise cooking.

[0040] Optionally,

[0041] The quantity of the food material is set by a user; or

[0048] Optionally, a duration from a time when the user submits the reservation to the reservation meal time set by the user is a 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 duration is, the greater the cumulative error of the timer is, and thus the earlier cooking is needed.

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

[0052] Further, 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 duration is in an increasing arithmetic sequence along with the linear increase of the reservation duration, and the method for determining the second compensation 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 parameter of the second compensation time length is reasonable.

[0058] Optionally, the control method comprises:

[0059] When the cooking appliance executes the scheduled cooking function, if the preset condition is met, the cooking is implemented by using the second cooking process, and the cooking is executed at the time of the second operation time length before the scheduled meal time;

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

[0061] According to the present application, the cooking appliance only closes the anti-overflow device when the scheduled function is executed under specific conditions, and the anti-overflow device works in other conditions, which can effectively prevent overflow.

[0062] Optionally, the preset condition comprises that the scheduled meal time is equal to or later than 21:00, or the scheduled meal time is equal to or earlier than 9:00.

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

[0064] Optionally, the preset condition further comprises that the scheduled meal time is more than 2 hours away from the time when the user submits the schedule.

[0065] According to the present application, if the user's scheduled meal time is very close, the anti-overflow device is made to work to prevent overflow.

[0066] The second aspect of the present application provides a cooking appliance, characterized in that comprising:

[0073] According to the present application, the anti-overflow device does not work when the cooking appliance performs the reservation cooking function, so as to avoid noise. In order to prevent overflow, the cooking appliance maintains the power reduction during the boiling stage when performing the reservation cooking function, but at the same time, the cooking time is extended based on the cooking time when the corresponding anti-overflow device works, so as to ensure that the food is fully cooked. At the same time, due to the error of the timer, the cooking time is delayed, so the cooking is also started in advance to a certain extent to ensure that the user obtains the meal at the reserved time.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0109] 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.

[0110] The cover 20 can be pivotably connected to the pot body 10 by a pivot shaft for covering 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 inner pot 11. It can be understood that the cooking space 12 is used for containing food materials. The cover 20 is usually provided with a steam valve (not shown) and a steam outlet 21, and the steam valve is in communication with the steam outlet 21. The steam in the cooking space 12 enters the steam valve through the steam outlet 21, and is discharged to the environment through the steam valve.

[0111] The cooking utensil 100 further comprises a control device (not shown) for realizing cooking control of the cooking utensil 100. The control device can be, for example, a micro control unit (MCU).

[0112] In addition, the cooking utensil 100 can also have a heating device (not shown) and a temperature measuring device (not shown). The heating device (for example, a heating disc, 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, for heating the inner pot 11 and the food materials therein under the control of the control device, so as to realize the cooking function. The temperature measuring device (for example, a temperature sensor) can be arranged at the bottom of the pot body 10, for sensing 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, so as to feed back the sensed bottom temperature to the control device, so that the control device can realize more accurate control based on the temperature information, for example, the heating device.

[0113] The cooking utensil 100 further has an interactive device 30 for realizing the human-computer interaction function. The interactive device 30 can include, for example, buttons, knobs, touch film keys, touch screens, display screens, etc. The interactive device 30 is electrically connected to the control device. The pre-arrangement function of the cooking utensil 100 is realized through the interactive device 30.

[0114] The cooking utensil 100 comprises a timer for timing, for example, timing the cooking time, timing the pre-arrangement time, etc. The timer is usually part of the control device. Usually, the cooking utensil 100 further comprises a timing display device, which is electrically connected to the control device (the timer) to display the timing under the control of the control device, for example, the countdown (the timing display device can be part of the interactive device 30, or can be arranged independently of the interactive device 30). In the case of pre-arranged cooking, the timing display device will display the pre-arrangement remaining time and / or the cooking remaining time in countdown.

[0115] As Figure 2As 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

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

[0121] In step S20, the control device is configured to: when the cooking appliance 100 executes a non-reserved cooking function, implement cooking by using the first cooking process; when the cooking appliance 100 executes a reserved cooking function, implement cooking by using the second cooking process, and start executing cooking at a time Ts before the second operation time to2 of the user-set reserved meal time Te (as shown in Figure 4 As shown in the figure, the second operation time to2 is greater than the second cooking time t2. In step S20, the cooking appliance 100 takes into account the cumulative error of the timer, so as not to delay the completion of cooking, the cooking appliance 100 starts cooking at a time Ts earlier than a time Tt before the second cooking time t2 (the time required to complete the cooking function) of the reserved meal time Te, so as to provide the user with cooked food at a time Tr no later than the reserved meal time Te (the time Tr is the time after the second cooking time t2 of the time Ts).

[0122] It can be seen that the anti-overflow 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 maintenance boiling stage, and in order to ensure that the food is fully cooked, the cooking time is increased. Therefore, cooking food in the second cooking process in the reserved mode can avoid the noise of the anti-overflow device 50 interfering with the user.

[0123] In the first cooking process, the cooking appliance 100 realizes anti-overflow by working the anti-overflow device. In the second cooking process, the cooking appliance 100 realizes anti-overflow by reducing the heating power in the maintenance boiling stage.

[0124] Alternatively, in step S20, the control device is configured to: when the cooking appliance 100 executes a non-reserved cooking function, implement cooking by using the first cooking process; when the cooking appliance 100 executes a reserved cooking function, implement cooking by using the second cooking process if a preset condition is met, and start executing cooking at a time Ts before the second operation time to2 of the reserved meal time Te.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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. 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.

[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 duration tk1 can be a preset value. Regardless of which cooking function the user selects, a fixed first compensation duration tk1 is added to the corresponding first cooking duration t1 as the second cooking duration t2.

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

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

[0133] Generally, the customer can reserve cooking at most 24 hours in advance, and the longest 24-hour reservation duration can be divided into three consecutive and different duration range intervals, and a first compensation duration tk1 is set corresponding to each duration interval. That is, when the reservation duration t0 is in the first duration range, the first compensation duration tk1 is the first cooking compensation duration tc1; when the reservation duration t0 is in the second duration range, the first compensation duration tk1 is the second cooking compensation duration tc2; when the reservation duration t0 is in the third duration range, the first compensation duration tk1 is the third cooking compensation duration tc3. Wherein, the first duration range, the second duration range and the third duration range are consecutive duration intervals, the value of the duration in the first duration range is less than the value of the duration in the second duration range, the value of the duration in the second duration range is less than the value of the duration in the third duration range, the first cooking compensation duration tc1 is less than the second cooking compensation duration tc2, and the second cooking compensation duration tc2 is less than the third cooking compensation duration tc3.

[0134] For example, the first duration range is [0, 240) minutes (within 4 hours), the first cooking compensation duration 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), the second cooking compensation duration 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 duration tc3 is 24 to 34 minutes (preferably 27 to 31 minutes, for example, 29 minutes).

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

[0136] For example, the second compensation duration tk2 can be set such that the reservation duration to increases by a first preset duration tp1, the second compensation duration tk2 increases by a second preset duration tp2. When the reservation duration to is less than the first preset duration tp1, the second compensation duration tk2 is 0. Thus, the longer the reservation duration to is, the longer the second compensation duration tk2 is; the shorter the reservation duration to is, the shorter the second compensation duration tk2 is. Along with the linear growth of the reservation duration to, the second compensation duration tk2 is an arithmetic sequence 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 to into several duration intervals corresponding to the second compensation duration tk2, and for each duration interval, the second compensation duration tk2 has a value. 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. Unlike the first compensation duration tk1, the division of the duration interval corresponding to the first compensation duration tk1 is non-uniform, while the division of the duration interval corresponding to the second compensation duration tk2 is uniform; the increase of the first compensation duration tk1 can be non-arithmetic (or can be 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 greater than the number of duration intervals corresponding to the second compensation duration tk2.

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

[0139] It can be understood that, for the same cooking function, the cooking time is related to the amount of food, the greater the amount of food, the longer the cooking time. Preferably, in the case of the same amount of food and cooking function, the working time of the maintaining boiling stage of the second cooking process is equal to the sum of the working time of the maintaining boiling stage of the first cooking process and the first compensation time tk1. That is, in the case of the same amount of food and cooking function, the extended cooking time is all compensated in the maintaining boiling stage with relatively reduced heating power, so as to ensure that the food is fully cooked.

[0140] Preferably, in the case of the same cooking function, the control device is configured to determine the first cooking time t1 according to the amount of food. Wherein, the greater the amount of food, the longer the first cooking time t1; the smaller the amount of food, the smaller the first cooking time t1. The amount of food can be set by the user through the interactive device 30, for example, the user sets the number of solid food or the number of diners on the interactive device 30 for the control device to calculate the amount of food. That is, the control device determines the first cooking time t1 according to the amount of food obtained from the interactive device 30. Alternatively, the amount of food can be obtained by weighing with the weighing device. That is, the control device determines the first cooking time according to the weight of the food weighed by the weighing device. The control device, for example, pre-stores the relationship between the amount of food and the cooking time under each cooking function, and the cooking curve (for example, the relationship curve of heating power, heating temperature and time) of different amounts of food under each cooking function, so that the cooking appliance 100 can accurately implement cooking according to the specific amount of food and the cooking function.

[0141] The control device, for example, stores a first cooking curve corresponding to the first cooking process in which the anti-overflow device 50 works, and a second cooking curve corresponding to the second cooking process in which the anti-overflow device 50 does not work, so as to implement the first cooking process and the second cooking process according to the first cooking curve and the second cooking curve respectively. In the case of the same amount of food and cooking function, the difference between the first cooking curve and the second cooking curve is the heating power and the working time of the maintaining boiling stage. Those skilled in the art can determine the first cooking curve of the cooking appliance 100 through experiments, and then correct the second cooking curve based on the first cooking curve, without the need 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 the first cooking time t1 is the same when the cooking function is the same. In the case of the same cooking function, the working time of the maintaining boiling stage of the second cooking process is equal to the sum of the working time of the maintaining boiling stage of the first cooking process and the first compensation time tk1.

[0143] Preferably, the control device is configured to, when the cooking appliance 100 performs the scheduled cooking function, implement the cooking by using the second cooking procedure in the case where the aforementioned preset condition is met, and start the cooking at the time Ts which is the time of the second operation duration to2 before the scheduled meal time Te; and implement the cooking by using the first cooking procedure in the case where the aforementioned preset condition is not met, and start the cooking at the time To which is the time of the first cooking duration t1 before the scheduled meal time Te, or start the cooking at the time Tt which is the time of 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, in the case where the aforementioned preset condition is not met (for example, the scheduled meal time Te is not in the noise sensitive period, and thus the noise interference does not need to be considered), the cooking appliance 100 performs the scheduled cooking function by using the first cooking procedure, so as to better prevent overflow. In this case, the cooking appliance 100 can consider the timer error, so as to cook in advance, so that the user obtains the meal no later than the scheduled meal time Te.

[0145] The process in which the cooking appliance 100 performs the scheduled cooking function by using the second cooking procedure will be described below in combination with Figure 4 and Figure 5 The process in which the cooking appliance 100 performs the scheduled cooking function by using the second cooking procedure will be described below in combination with

[0146] Example One

[0147] The time Tf at which the user submits the schedule is 15:00, and the scheduled meal time Te is 18:00.

[0148] According to Tf and Te, the scheduling duration t0 is 180 minutes, which belongs to the first duration range, the first compensation duration tk1 takes the value of the first cooking compensation duration tc1, and the second compensation duration tk2 is one second preset duration tp2 (the scheduling duration t0 includes one first preset duration tp1), which is 1 minute. Thus:

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

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

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

[0152] Thus, the cooking appliance 100 starts to perform the cooking at the time Ts (16:50) which is 70 minutes before the reservation meal time Te, i.e. at the time which is 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 works and finishes the cooking with the second cooking time t2 (69 minutes).

[0154] Example Two

[0155] The user submits the reservation at the time Tf which is 12:00 and the reservation meal time Te is 18:00.

[0156] According to Tf and Te, 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 times tp2 (the reservation time t0 includes two first preset times tp1), which is 2 minutes. Thus:

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

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

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

[0160] Thus, the cooking appliance 100 starts to perform the cooking at the time Ts (16:39) which is 81 minutes before the reservation meal time Te, i.e. at the time which is 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 works and finishes the cooking with the second cooking time t2 (79 minutes).

[0162] Example Three

[0163] The user submits the reservation at the time Tf which is 12:00 and the reservation meal time Te is the next day 8:00.

[0164] According to the reservation time length t0 of 1200 minutes known from Tf and Te, the first compensation time length tk1 takes the value of the third cooking compensation time length tc3, and the second compensation time length tk2 is six second preset time lengths tp2 (the reservation time length t0 includes six first preset time lengths tp1), which is 6 minutes. Thus:

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

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

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

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

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

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