[0087] The realization, functional features, and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0088] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0089] It should be noted that if there are directional indications involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0090] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and should not be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0091] Current cooking appliances can achieve various cooking functions. After cooking is completed, only a small amount of moisture or no moisture remains in the food inside the cooking appliance due to cooking. If the user does not transfer the food in time after cooking is completed, causing the high-temperature food to still remain inside the cooking appliance, it will cause the cooked food to be affected by preheating, the temperature will continue to rise, resulting in the food being burned and sticking to the bottom, reducing the user experience.

[0092] In view of this, the present invention provides a control method for a cooking appliance and a cooking appliance. Figure 1 and Figure 2 is an embodiment of the cooking appliance provided by the present invention. Figures 3 to 19 is an embodiment of the control method for the cooking appliance provided by the present invention.

[0093] See Figure 1 , the cooking appliance 100 proposed by the present invention includes a heating container 1, a heating device 2, a cooling device 3, a detection device, and a control device. The heating container 1 has a cooking cavity. The heating device 2 is provided on the heating container 1 for heating the cooking cavity. The cooling device 3 is provided on the heating container 1 for cooling the heating container 1. The detection device is used to detect the cooking parameters of the cooking cavity. The control device is electrically connected to the heating device 2, the cooling device 3, and the detection device.

[0094] The embodiments of the present invention do not limit the specific form of the heating device 2. It can be a hot plate, electromagnetic heating technology, heating tape, resistance wire, infrared, etc. It should be understood that the heating device 2 can mainly heat the cooking cavity, and different heating forms can be correspondingly arranged at different positions. The present invention does not limit this.

[0095] It should be noted that in an embodiment of the present invention, the cooling device 3 includes an air flow driving cooling device. The air flow driving cooling device can be a device such as a blower that can send air into the air duct. This embodiment does not make specific limitations on this. Since the air flow driving device drives the air flow in the air duct inside the cooking appliance to flow towards the cavity wall of the cooking cavity, so as to achieve the purpose of cooling. Different from traditional cooling means such as water vapor cooling, semiconductor cooling, and compressor cooling, when the cooking cavity is cooled by the air flow driving device, the distribution of the air flow in the cooking cavity is relatively uniform, the cooling is more uniform, and compared with the traditional cooling method, the cost is lower, which is more suitable for cooling the cooking appliance.

[0096] It should be noted that in an embodiment of the present invention, the heating container 1 includes an inner container, and the space surrounded by the inner container forms a cooking cavity. The air outlet end of the cooling device 3, such as a blower, faces the inner container of the heating container 1 to cool and depressurize the cooking cavity. In this embodiment, the cooking cavity is cooled and depressurized by blowing air, and the cooling device 3 can be set at any position according to different product space limitations.

[0097] It can be understood that the detection device is used to detect the cooking parameters of the cooking cavity. The cooking parameters can include parameters such as the temperature and pressure in the cooking cavity. The temperature in the cooking cavity can be detected by a temperature detection device, so a temperature detection device can be set in the cooking cavity. The pressure in the cooking cavity can be detected by a pressure detection device, so a pressure detection device can be set in the cooking cavity. The temperature detection device and the pressure detection device can be set at any position in the cooking cavity according to different product space limitations.

[0098] The control device in the cooking appliance 100 includes a memory, a processor, and a control program of the cooking appliance stored on the memory and executable on the processor. The control program of the cooking appliance is configured to implement the steps of the control method of the cooking appliance.

[0099] Refer to Figure 2 , Figure 2 which is a schematic structural diagram of the control device for the hardware operating environment involved in the embodiment solution of the present invention.

[0100] Such as Figure 2As shown in the figure, the control device may include: a processor 1001, such as a central processing unit, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard. Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface. The memory 1005 may be a high-speed random access memory or a stable non-volatile memory, such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0101] Those skilled in the art can understand that Figure 2 the structure shown in the figure does not constitute a limitation on the control device, and it may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0102] As Figure 2 shown, the memory 1005, as a storage medium, may include an operating system, a network communication device, a user interface device, and a control program for the cooking appliance.

[0103] In Figure 2 the control device shown in the figure, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the control device of the present invention may be arranged in the control device. The control device calls the control program for the cooking appliance stored in the memory 1005 through the processor 1001 and executes the control method for the cooking appliance provided in the embodiments of the present invention.

[0104] The embodiments of the present invention provide a control method for a cooking appliance. Referring to Figure 3 , Figure 3 is a schematic flowchart of an embodiment of a control method for a cooking appliance of the present invention.

[0105] The control method for the cooking appliance includes the following steps:

[0106] Step S1: After the heating device 2 works, control the cooling device 3 to be in a working state for at least a period of time during the cooling stage of the cooking appliance 100 to cool the lower part of the heating container 1.

[0107] It should be noted that the cooking stage of the cooking appliance 100 may refer to the stage when the heating device 2 is turned on, and the cooling stage of the cooking appliance 100 may refer to the stage when the heating device 2 stops working, that is, after the heating device is turned off, it is considered that the cooking appliance 100 enters the cooling stage.

[0108] Under normal circumstances, during the cooling stage of the cooking appliance 100, although the heating device 2 has stopped working, there is still residual heat. The temperature of the food remaining in the cooking cavity continues to rise. Therefore, controlling the cooling device 3 to be in the working state during the cooling stage can eliminate the residual heat after the heating device 2 stops working. Controlling the cooling device 3 to be in the working state can mean turning on the cooling device 3.

[0109] In this embodiment, there is no specific limitation on the timing of turning on the cooling device, as long as it can achieve controlling the cooling device 3 to be in the working state for at least a period of time during the cooling stage. For example, it can mean controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the working state throughout the cooling stage. It can also mean controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the working state for a period of time after entering the cooling stage. It can also mean controlling the cooling device 3 to be in the working state when the cooking appliance 100 has not completed the cooking stage and is about to end the cooking stage, and controlling the cooling device 3 to continue to be in the working state for a period of time after entering the cooling stage.

[0110] Thus, in the technical solution of the present invention, after the heating device works, the cooling device is controlled to be in the working state for at least a period of time during the cooling stage of the cooking appliance 100 to cool the heating container. To achieve cooling the remaining food with the cooling device for a period of time during the cooling stage of the cooking appliance 100 after the food cooking is completed, offsetting the influence of the residual heat in the cooking appliance 100, thereby preventing the food in the appliance from being burnt and sticking to the bottom, and improving the user experience.

[0111] In an embodiment of the present invention, step S1 may include: after the heating device 2 works, and when the cooking appliance 100 enters the cooling stage, controlling the cooling device 3 to start working for a period of time.

[0112] It can mean controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the working state throughout the cooling stage, or it can mean controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the working state for a period of time after entering the cooling stage.

[0113] Thus, when the cooking stage ends and the cooking appliance 100 enters the cooling stage, the cooling device is started to quickly cool the food in the cooking cavity; the food temperature is decreased within a short time, offsetting the influence of the residual heat of the heating device 2, thereby preventing the food in the cooking cavity from being burnt.

[0114] See Figure 4 , Figure 4Schematic flowchart of another embodiment of a control method for a cooking appliance according to the present invention.

[0115] Step S1 includes the following sub-steps:

[0116] Step S11a: After the heating device 2 operates, obtain the actual cooking duration of the cooking cavity.

[0117] The actual cooking duration of the cooking cavity can refer to the duration when the heating device 2 is actually turned on. Specifically, it can refer to starting to time from when the heating device 2 is turned on until the heating device 2 is turned off.

[0118] Step S12a: When the actual cooking duration reaches the target cooking duration, control the cooking appliance 100 to enter the cooling stage, and control the cooling device 3 to operate for a period of time.

[0119] Under normal circumstances, according to different cooking modes, the target cooking duration is different. The target cooking duration can refer to a certain value in a certain cooking mode. After the heating device 2 operates, starting to time from when the heating device 2 is turned on until the target cooking duration, the heating device 2 is turned off, and the cooking appliance 100 enters the cooling stage. It can be understood that when the on-time of the heating device 2 reaches the target cooking duration, the cooking appliance 100 enters the cooling stage. It can refer to controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the operating state throughout the cooling stage. It can also refer to controlling the cooling device to turn on when the cooking appliance 100 enters the cooling stage, and controlling the cooling device 3 to be in the operating state for a period of time after entering the cooling stage.

[0120] Thus, at the end of the cooking stage, that is, as soon as entering the cooling stage, the cooling device is started to quickly cool the food in the cooking cavity; the food temperature is decreased within a short time to offset the influence of the residual heat of the heating device 2, thereby preventing the food in the cooking cavity from being burnt.

[0121] In another embodiment of the present invention, step S1 may further include: after the heating device 2 operates, and before the cooking appliance 100 enters the cooling stage, control the cooling device 3 to turn on and maintain the operation of the cooling device 3, so that after the cooking appliance 100 enters the cooling stage, the cooling device 3 operates for a period of time.

[0122] Thus, before the cooking stage is over and before the cooking appliance 100 enters the cooling stage, the cooling device is started to quickly cool the food in the cooking cavity; and after the cooking appliance 100 enters the cooling stage, the cooling device 3 is maintained to operate for a period of time, and the food temperature is decreased within a short time to offset the influence of the residual heat of the heating device 2, thereby preventing the food in the cooking cavity.

[0123] See Figure 5 ,Figure 5 Schematic flow chart of another embodiment of a control method for a cooking appliance according to the present invention.

[0124] The step S1 includes the following sub-steps:

[0125] Step S11b: After the heating device 2 operates, obtain the actual cooking duration of the cooking cavity.

[0126] The actual cooking duration of the cooking cavity may refer to the duration when the heating device 2 is actually turned on. Specifically, it may start timing from when the heating device 2 is turned on until the heating device 2 is turned off.

[0127] Step S12b: When the actual cooking duration reaches a preset duration, control the cooling device 3 to turn on and maintain the operation of the cooling device 3, so that after the cooking appliance 100 enters the cooling stage, the cooling device 3 operates for a period of time. Wherein, the preset duration is less than the target cooking duration.

[0128] The target cooking duration may refer to a certain value in a certain cooking mode. After the heating device 2 operates, starting from when the heating device 2 is turned on, until the target cooking duration, the heating device 2 is turned off and the cooking appliance 100 enters the cooling stage. It can be understood that when the on-time of the heating device 2 reaches the target cooking duration, the cooking appliance 100 enters the cooling stage. The preset duration is less than the target cooking duration, that is, before the cooking stage is over and before the cooking appliance 100 enters the cooling stage, the cooling device is started to quickly cool the food in the cooking cavity; and after the cooking appliance 100 enters the cooling stage, the cooling device 3 is maintained to operate for a period of time to reduce the food temperature in a short time and offset the influence of the residual heat of the heating device 2, thereby avoiding the food in the cooking cavity.

[0129] See Figure 6 , in an embodiment of the present invention, step S12b may include the following sub-steps:

[0130] S12b1: Obtain the amount of ingredients in the cooking cavity and the cooking target parameters.

[0131] The amount of ingredients in the cooking cavity can be obtained in various ways. For example, it can be obtained by weighing before the ingredients are loaded into the cooking cavity, or it can be obtained after the ingredients are loaded into the cooking cavity. After the ingredients are loaded into the cooking cavity, it can be obtained by various ways such as a weight sensor, a timer, etc. The present invention does not specifically limit this.

[0132] The cooking target parameters include at least one of a cooking mode, a cooking target temperature, a cooking target power, and a cooking target duration, and the cooking target parameters can be a certain value. The cooking mode has different selections according to the model or category of the cooking appliance 100. For example, a stir-fry machine can have functions such as frying, stir-frying, and sautéing, and this embodiment does not make specific limitations thereto.

[0133] S12b2: Determine the preset duration according to the amount of ingredients in the cooking cavity and the cooking target parameters.

[0134] Since under the conditions of different amounts of ingredients and different cooking target parameters, the residual heat generated at the end of the cooking stage is different, and thus the time point for turning on the cooling device is different. For example, the higher the cooking target temperature, the higher the cooking target power, or the longer the cooking target duration, and the less the amount of ingredients in the cooking cavity, the earlier the food may need to be cooled, and the longer the preset duration can be, that is, the earlier the time point for turning on the cooling device can be.

[0135] S12b3: When the actual cooking duration reaches the preset duration, control the cooling device 3 to turn on and maintain the operation of the cooling device 3, so that after the cooking appliance 100 enters the cooling stage, the cooling device 3 operates for a period of time.

[0136] Thus, by considering the amount of ingredients added to the cooking cavity and the cooking target parameters, the temperature of the food in the cooking cavity can be controlled more precisely, the temperature of the food can be decreased in a short time, and the influence of the residual heat of the heating device 2 can be offset, thereby avoiding the food in the cooking cavity.

[0137] See Figure 7 , in an embodiment of the present invention, the step S1 includes the following sub-steps:

[0138] Step S11c: After the heating device 2 operates, control the cooling device 3 to be in a set operating mode for at least a period of time in the cooling stage of the cooking appliance 100.

[0139] After the cooling device 3 is turned on, the operating mode of the cooling device can be a set mode. For example, the cooling device can operate at different gears in this set mode, and the settings of each gear can be v1: 1000 revolutions, v2: 1200 revolutions, v3: 1500 revolutions, v4: 1800 revolutions, v5: 2100 revolutions, v6: 2400 revolutions, v7: 2700 revolutions, v8: 3000 revolutions, and v9: 3600 revolutions. This embodiment does not make specific limitations thereto.

[0140] Step S12c: In the set operating mode, at every interval of the first preset time, obtain the first temperature parameter of the cooking cavity and obtain the temperature difference between the first temperature parameters obtained twice in succession.

[0141] The first temperature parameter of the cooking cavity refers to the temperature at the inner bottom of the cooking cavity. This temperature can be the average temperature of the entire bottom or the maximum temperature. This embodiment does not make specific restrictions on this.

[0142] Step S13c: According to the temperature difference, control the cooling device 3 to operate with a first working parameter matching the current temperature difference to cool the heating container 1, so that the temperature reduction speed in the cooking cavity is greater than the minimum temperature reduction speed.

[0143] The temperature change trend in the cooking cavity can be judged by the temperature differences obtained at the same interval. If the temperature difference is small, it means that the temperature drops slowly. If the temperature difference is large, it means that the temperature drops quickly.

[0144] If the temperature difference between the current temperature in the cooking cavity and the temperature detected last time is less than the minimum temperature reduction speed, it means that the temperature drops slowly. At this time, the rotation speed of the driving cooling device can be increased to increase the temperature reduction speed in the cooking cavity. Generally, only one cooling device rotation speed gear is adjusted each time to avoid too fast temperature drop and affect the taste of the processed food. If the temperature difference between the current temperature in the cooking cavity and the temperature detected last time is greater than the minimum temperature reduction speed, it means that the temperature drops appropriately. At this time, the rotation speed gear of the cooling device can be not adjusted.

[0145] See Figure 8 , in an embodiment of the present invention, step S12c includes the following sub-steps:

[0146] S12c1: Obtain the cooking target parameters, and determine the first preset time according to the cooking target parameters.

[0147] The cooking target parameters include at least one of a cooking mode, a cooking target temperature, a cooking target power, and a cooking target duration. The first preset time, that is, the cooling detection period, can be determined according to, for example, the cooking mode to improve the precise monitoring of temperature detection and achieve precise control of the temperature in the cooking cavity. Among them, the first preset time can have different values according to different current cooking modes of the cooking appliance 100. The cooking mode has different selections according to the model or category of the cooking appliance 100. For example, a stir-fry machine can have functions such as frying, stir-frying, and sautéing. This embodiment does not make specific restrictions on this.

[0148] S12c2: Every time the first preset time elapses, obtain the first temperature parameter of the cooking cavity, and obtain the temperature difference between the first temperature parameters obtained twice in succession.

[0149] The temperature change trend in the cooking cavity can be judged by the temperature differences obtained at the same interval. If the temperature difference is small, it means that the temperature drops slowly. If the temperature difference is large, it means that the temperature drops quickly.

[0150] See Figure 9 In an embodiment of the present invention, after step S1, the following is further included:

[0151] Step S2a: Obtain the second temperature parameter of the cooking cavity, and when the second temperature parameter drops to the target temperature reduction value, control the cooling device 3 to turn off.

[0152] When the temperature in the cooking cavity drops to a target temperature reduction value, it indicates that the food in the cooking cavity has been quickly cooled to a temperature where it will not burn. At this time, turning off the cooling device can ensure that the food in the cooking cavity does not burn while reducing the cooling rate of the food for heat preservation to avoid the food temperature being too low and affecting the taste.

[0153] See Figure 10 In an embodiment of the present invention, step S2a includes the following sub-steps:

[0154] Step S21a: Obtain the cooking target parameter, and determine the target temperature reduction value according to the cooking target parameter.

[0155] The target temperature reduction value can be determined according to, for example, the cooking mode in the cooking target parameter to achieve precise control of the temperature reduction, thereby avoiding the food temperature being too low and affecting the taste.

[0156] Step S22a: Obtain the second temperature parameter of the cooking cavity, and when the second temperature parameter drops to the target temperature reduction value, control the cooling device 3 to turn off.

[0157] When the second temperature parameter drops to a target temperature reduction value, it indicates that the food in the cooking cavity has been quickly cooled to a temperature where it will not burn. At this time, turning off the cooling device can ensure that the food in the cooking cavity does not burn while reducing the cooling rate of the food for heat preservation to avoid the food temperature being too low and affecting the taste.

[0158] See Figure 11 In an embodiment of the present invention, after step S1, the following is further included:

[0159] Step S2b: Obtain the opening duration of the cooling device 3, and when the opening duration is greater than the maximum timing value, control the cooling device 3 to operate with the second working parameter so that the temperature in the cooking cavity drops to the target temperature reduction value.

[0160] The opening duration of the cooling device 3 can be used to determine whether the temperature in the cooking cavity drops at the expected speed. If the opening duration is greater than the maximum timing value, the temperature in the cooking cavity may not have dropped to the target temperature reduction value yet, and the second working parameter of the cooling device 3 can be appropriately adjusted so that the temperature in the cooking cavity drops to the target temperature reduction value.

[0161] See Figure 12, in an embodiment of the present invention, the step S2b includes the following sub-steps:

[0162] Step S21b: Obtain the cooking target parameters, and determine the target temperature reduction value and the maximum timing value according to the cooking target parameters.

[0163] The maximum timing value can be the theoretical temperature reduction duration. The theoretical temperature reduction duration can be estimated according to the cooking target parameters. For example, the theoretical temperature reduction durations corresponding to the stir-fry mode and the frying mode are different. The theoretical temperature reduction duration can refer to the theoretical time for the food to quickly drop to the target temperature reduction value under the cooking mode, cooking target temperature, cooking target power, and cooking target duration in the cooking stage.

[0164] Step S22b: Obtain the opening duration of the cooling device 3. When the opening duration is greater than the maximum timing value, control the cooling device 3 to work with the second working parameters so that the temperature in the cooking cavity drops to the target temperature reduction value.

[0165] If the opening duration of the cooling device 3 is greater than the maximum timing value, that is, greater than its theoretical temperature reduction duration, it means that the temperature in the cooking cavity is relatively high and further cooling is required. At this time, the rotation speed gear of the cooling device can be increased to accelerate the temperature drop so that the temperature in the cooking cavity drops to the target temperature reduction value.

[0166] See Figure 13 , in an embodiment of the present invention, before the step 1, it further includes:

[0167] Step S0a: Obtain the amount of ingredients in the cooking cavity and the cooking target parameters, and determine the initial working parameters of the cooling device 3 in the working state according to the amount of ingredients in the cooking cavity and the cooking target parameters.

[0168] Selecting the corresponding initial working parameters of the cooling device 3 according to the amount of ingredients in the cooking cavity of the cooking appliance 100 and the cooking target parameters can not only achieve the purpose of rapid cooling but also prevent the processed food from quickly getting cold and affecting the consumption.

[0169] See Figure 14 , in an embodiment of the present invention, before the step S1, it further includes:

[0170] Step S0b: When the temperature in the cooking cavity reaches the first set temperature value, control the cooking appliance 100 to enter the cooking stage, and in the cooking stage, control the cooling device 3 to be turned on.

[0171] When the temperature in the cooking cavity reaches the first set temperature value, it means that the cooking appliance 100 has completed preheating. After entering the cooking stage, the heating device and the cooling device can work simultaneously to more precisely control the cooking temperature in the cooking stage.

[0172] See Figure 15 , in an embodiment of the present invention, the step S0b includes the following sub-steps:

[0173] Step S01b: When the temperature of the cooking cavity reaches the first set temperature value, control the cooking appliance 100 to enter the cooking stage.

[0174] When the temperature of the cooking cavity reaches the first set temperature value, it indicates that the cooking appliance 100 has completed preheating and enters the cooking stage.

[0175] Step S02b: In the cooking stage, control the cooling device 3 and the heating device 2 to operate with the third working parameter so that the temperature in the cooking cavity is between the maximum temperature value and the minimum temperature value.

[0176] If the current temperature of the cooking cavity is greater than the upper limit of the cooking target temperature in the cooking stage, it indicates that the temperature of the cooking cavity is too high and there is a risk of food burning. At this time, the heating device can be controlled to stop heating, or the cooling device can be driven to operate at a certain speed to appropriately reduce the temperature in the cooking cavity; if the current temperature of the cooking cavity is within the preset cooking temperature control range, it means that the temperature in the cooking cavity at this time is not enough to burn the food, and the heating device can be operated according to the normal method of cooking food, and the cooling device can be turned off; if the current temperature of the cooking cavity is less than the minimum value of the preset cooking temperature control range, it means that the temperature in the cooking cavity is too low at this time, which may affect the processing of food, resulting in food processing failure and affecting the user's use. At this time, the power of the heating device can be increased so that the temperature in the cooking cavity rises to meet the food processing requirements.

[0177] In an embodiment of the present invention, the third working parameter of the heating device 2 includes the duration of a single working cycle of the heating device 2.

[0178] The third working parameters of the cooling device 3 and the heating device 2 are related to the specific forms of the cooling device 3 and the heating device 2. The present invention does not specifically limit this. For example, when the heating device 2 is a heating belt, its working method is usually power adjustable, and the third working parameter of the heating device 2 can be power at this time. When the heating device 2 is a hot plate, the working form of the hot plate is usually heating ratio adjustable. The heating ratio is the ratio of the heating time of the heating device 2 to the cooking cavity to the stop heating time, and the third working parameter can be the heating ratio at this time. When the cooling device 3 is a fan assembly, the third working parameter of the cooling device 3 can be power or wind speed, etc.

[0179] It should be noted that the duration of a single working cycle of the heating device 2 can be achieved by adjusting the heating ratio of the heating device 2. Thus, the heating device 2 heats the cooking cavity intermittently. For example, the heating ratio of the heating device 2 is 16 / 30, its single working cycle duration is 16 seconds, and the stop heating time is 14 seconds.

[0180] See Figure 16 , in an embodiment of the present invention, before the step S01b, the following steps are further included:

[0181] Step S00, obtaining the amount of ingredients in the cooking cavity; according to the amount of ingredients in the cooking cavity, determining the third working parameters of the cooling device 3 and the heating device 2 in the cooking stage.

[0182] The amount of ingredients in the cooking cavity can be obtained in various ways. For example, it can be obtained by weighing before the ingredients are loaded into the cooking cavity, or it can be obtained after the ingredients are loaded into the cooking cavity. After the ingredients are loaded into the cooking cavity, it can be obtained through various ways such as a weight sensor, a timer, etc. The present invention does not specifically limit this.

[0183] Thus, according to different amounts of ingredients, the on-demand operation of the cooling device 3 and the heating device 2 in the cooking stage can be determined to avoid waste of energy.

[0184] See Figure 17 , in an embodiment of the present invention, the step S01b includes the following sub-steps:

[0185] Step S01b1: When the temperature of the cooking cavity reaches the first set temperature value, turn off the heating device 2.

[0186] It should be noted that in the preheating stage, the heating chassis can be controlled to heat at the maximum power, and the temperature in the cooking cavity can be detected in real time. At this time, by comparing the current temperature in the cooking cavity with the first set temperature value, when the current temperature is greater than the first set temperature value, it indicates that the preheating stage is over and the cooking stage can be entered. The first set temperature value can be a certain value, and this embodiment does not specifically limit this.

[0187] Step S01b2: After an interval of the second preset time, control the cooking appliance 100 to enter the cooking stage, restart the heating device 2, and in the cooking stage, control the cooling device 3 to turn on.

[0188] In this embodiment, in order to accurately operate the cooking stage and prevent the influence of the residual temperature in the preheating stage, after the preheating stage is over, the heating chassis is turned off, and after an interval of the second preset time, the cooking appliance is controlled to enter the cooking stage, thereby reducing the influence brought by the high temperature in the preheating stage.

[0189] See Figure 18 , in an embodiment of the present invention, before the step S1, the following steps are further included:

[0190] Step S0c: When the heating device 2 is turned on and the temperature in the cooking cavity reaches the first set temperature value, start timing; according to the value of the timing, obtain the amount of food in the cooking cavity.

[0191] In this embodiment, the amount of cooked food is judged according to the timing duration. The more the amount of food, the longer the time required to cook the food to the target temperature. There is a correlation between the cooking duration and the amount of food. Thus, by recording the timing from when the heating device 2 is turned on until the temperature in the cooking cavity reaches the first set temperature value, the amount of food can be judged, and there is no need to set an additional detection device to detect the amount of food.

[0192] The following uses two specific embodiments to illustrate the specific implementation manners of the control method of the cooking appliance of the present invention.

[0193] Embodiment 1

[0194] See Figure 19 , in the embodiment of the present invention, the working stages of the cooking appliance 100 sequentially include: a preheating stage, a cooking stage, and a cooling stage. In the embodiment of the present invention, the cooling device 3 is a blower, and the wind speed of the cooling device 3 refers to the wind speed of the blower.

[0195] Preheating stage: Turn on the heating device 2 with a high power adjustment ratio to enter the preheating stage. When the temperature in the cooking cavity reaches the first set temperature value, turn off the heating device 2.

[0196] Exemplarily, Table 1 below shows the relationship between the cooking mode and the power adjustment ratio of the heating device in the preheating stage.

[0197] Table 1

[0198] Cooking mode Frying Stir-frying Power adjustment ratio of heating device 12 / 16 14 / 16

[0199] When the heating device 2 is turned on and the temperature in the cooking cavity reaches the first set temperature value, start timing.

[0200] Cooking stage:

[0201] After an interval of a second preset time, control the cooking appliance 100 to enter the cooking stage, restart the heating device 2, and in the cooking stage, control the cooling device 3 to be turned on.

[0202] According to the value of the timing, obtain the amount of food in the cooking cavity; according to the amount of food in the cooking cavity, determine the third working parameters of the cooling device 3 and the heating device 2 in the cooking stage.

[0203] In the cooking stage, control the cooling device 3 and the heating device 2 to work with the third working parameters so that the temperature in the cooking cavity is between the maximum temperature and the minimum temperature.

[0204] Exemplarily, Table 2 below shows the relationship between the first timing, the amount of ingredients, the heating device, and the third parameter of the cooling device.

[0205] Table 2

[0206]

[0207] Cooling stage:

[0208] (1) Obtain the amount of ingredients in the cooking cavity and the cooking target parameters, and determine the initial working parameters of the cooling device 3 in the working state according to the amount of ingredients in the cooking cavity and the cooking target parameters.

[0209] Exemplarily, the relationship between the amount of ingredients in the cooking cavity, the cooking target parameters, and the initial working parameters of the cooling device 3 is shown in Table 3. Among them, the cooking target temperature of 180°C / ingredient amount level of 1 in Table 3 means that when the cooking target temperature is 180°C, the ingredient amount level is 1.

[0210] Table 3

[0211]

[0212] After the heating device 2 works, obtain the actual cooking duration in the cooking cavity. When the actual cooking duration reaches the target cooking duration, control the cooking appliance 100 to enter the cooling stage, and control the cooling device 3 to start working for a period of time.

[0213] Control the cooling device 3 to be in the set working mode at least for a period of time during the cooling stage of the cooking appliance 100. Every first preset time interval, obtain the first temperature parameter in the cooking cavity, and obtain the temperature difference between two adjacent first temperature parameters obtained. According to the temperature difference, control the cooling device 3 to work with the first working parameter matching the current temperature difference to cool the heating container 1, so that the cooling speed in the cooking cavity is greater than the minimum cooling speed.

[0214] Among them, obtain the cooking target parameters, and determine the first preset time according to the cooking target parameters.

[0215] Exemplarily, Table 4 shows the relationship between the cooking target parameters and the first preset time.

[0216] Table 4

[0217] Cooking mode Frying Stir-frying First preset time 10 6

[0218] Obtain the second temperature parameter in the cooking cavity. When the second temperature parameter drops to the target cooling value, control the cooling device 3 to turn off.

[0219] Among them, obtain the cooking target parameters, and determine the target cooling value according to the cooking target parameters.

[0220] Exemplarily, Table 5 shows the relationship between cooking target parameters and target temperature reduction values.

[0221] Table 5

[0222] Cooking mode Stir-frying Target temperature reduction value 100 90

[0223] Embodiment 2

[0224] The difference between this embodiment and Embodiment 1 lies in the different steps in the temperature reduction stage.

[0225] Temperature reduction stage:

[0226] Obtain the opening duration of the temperature reduction device 3. When the opening duration is greater than the maximum timing value, control the temperature reduction device 3 to work with the second working parameter to reduce the temperature in the cooking cavity to the target temperature reduction value.

[0227] Among them, obtain the cooking target parameters, and determine the target temperature reduction value and the maximum timing value according to the cooking target parameters.

[0228] Exemplarily, Table 5 shows the relationship between cooking modes and maximum timing values.

[0229] Table 5

[0230]

[0231] See Figure 19 , Figure 19 are the cooking temperature curves of the conventional stir-fry function and the stir-fry function cooking curves controlled by the control methods of Embodiments 1 and 2 of the present invention. Compared with the conventional stir-fry function cooking curve, the difference in the cooking curve controlled by the anti-sticking method is that: at the end or near the end of the cooking stage, start the temperature reduction device to quickly reduce the temperature of the food in the inner pot; within a short time, reduce the food temperature to the target temperature at which it will not burn and stick to the bottom, thereby protecting the food in the inner pot.

In specific applications, those skilled in the art can set according to needs, and the present invention does not make any restrictions on this.
