Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a control method for a cooking appliance, a control device for a cooking appliance, a cooking appliance, and a readable storage medium. Background Art

[0002] In the related art, cooking utensils only heat for a fixed time and at a fixed temperature during cooking. However, this heating method is only applicable to a few fixed amounts of ingredients and cannot achieve a good cooking effect for other amounts of ingredients. Therefore, how to accurately judge the amount of ingredients in the cooking utensils has become an urgent problem to be solved. Summary of the Invention

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

[0004] To this end, a first aspect of the present invention provides a method for controlling a cooking appliance.

[0005] A second aspect of the present invention provides a control device for a cooking appliance.

[0006] A third aspect of the present invention provides a cooking appliance.

[0007] A fourth aspect of the present invention provides a readable storage medium.

[0008] In view of this, a first aspect of the present invention proposes a control method for a cooking appliance, wherein the cooking appliance includes a cooking cavity; the control method includes: obtaining a preset temperature at the bottom of the cooking cavity within a preset time period based on the start of the cooking appliance; and determining the amount of food in the cooking cavity based on the preset temperature.

[0009] The control method of the cooking appliance provided by the present invention first obtains a preset time period during the operation of the cooking appliance after the cooking appliance starts operating, and the preset time period can be at least two; then, a preset temperature of the bottom of the cooking cavity is obtained in each preset time period; finally, the amount of food in the cooking cavity is determined based on the corresponding preset temperature obtained in each preset time period, thereby realizing the determination of the amount of food in the cooking cavity.

[0010] Specifically, the ingredients in the cooking cavity can be rice, millet or other rice ingredients. During the cooking process, the cooking appliance can obtain a preset temperature within at least one preset time period and determine the amount of rice in the cooking cavity according to the preset temperature. Therefore, the operating parameters of the cooking appliance can be controlled according to the amount of rice, thereby avoiding the phenomenon that the cooked rice is undercooked, the bottom is mushy or too watery, and ensuring the cooking effect.

[0011] Specifically, the cooking appliance may be provided with a temperature detection element, and the temperature detection element is provided at the bottom of the cooking cavity for detecting the temperature of the bottom of the cooking cavity.

[0012] The control method of the cooking appliance provided by the present invention detects the temperature of the bottom of the cooking cavity during the operation of the cooking appliance, so as to detect the temperature of the food in direct contact with the bottom of the cooking cavity, thereby preventing the food from being mushy due to excessively high temperature, or from being unable to be effectively cooked due to excessively low temperature. Furthermore, by obtaining the preset temperature of the bottom of the cooking cavity within a preset time period, the amount of food in the cooking cavity can be determined according to the temperature of the bottom of the cooking cavity within the preset time period, so that the cooking appliance can adjust the corresponding operating parameters according to the amount of food in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0013] In addition, the cooking appliance control method according to the above technical solution provided by the present invention may also have the following additional technical features:

[0014] In the above technical solution, further, the step of obtaining a preset temperature of the bottom of the cooking cavity within a preset time period includes: obtaining the temperature of the bottom of the cooking cavity; based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stopping heating the cooking cavity and continuing for a first time period; obtaining a first maximum temperature of the bottom of the cooking cavity within the first time period; based on the heating stop time reaching the first time period, heating the cooking cavity and continuing for a second time period; obtaining a first minimum temperature of the bottom of the cooking cavity within the second time period.

[0015] In this technical solution, the preset temperature of the bottom of the cooking cavity in two preset time periods during the operation of the cooking appliance can be obtained, and then the amount of food in the cooking cavity can be judged based on the preset temperatures corresponding to the two preset time periods.

[0016] Specifically, after the cooking appliance begins operating, the heating device may begin heating the cooking cavity and, via a temperature detector, obtain real-time data on the temperature of the bottom of the cooking cavity. When the temperature of the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to cease operation, i.e., to stop heating the cooking cavity, for a first duration, which is a preset time period during the operation of the cooking appliance. During the first duration, the temperature of the bottom of the cooking cavity continues to be obtained via the temperature detector, and the highest temperature of the bottom of the cooking cavity during the first duration is recorded. This highest temperature is the preset temperature value within the preset time period of the first duration, i.e., the first highest temperature. It should be noted that, after the heating device ceases operation, the temperature of the bottom of the cooking cavity does not immediately decrease, but instead continues to increase, due to the relatively high residual heat of the heating device. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device ceases heating is not the highest temperature of the bottom of the cooking cavity during the first duration.

[0017] Furthermore, when the heating device stops heating the cooking cavity for a first time period, the heating device is turned on to heat the cooking cavity for a second time period, which is another preset time period during the operation of the cooking appliance. During the second time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detection element, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature during the second preset time period, i.e., the first lowest temperature. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately increase, but instead continues to decrease. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device begins heating is not the lowest temperature of the bottom of the cooking cavity during the second time period.

[0018] Furthermore, the amount of food in the cooking cavity is determined by the first maximum temperature and the first minimum temperature, thereby ensuring the accuracy of the determination of the amount of food in the cooking cavity. Then, the parameters of the cooking appliance can be controlled according to the amount of food in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0019] In any of the above technical solutions, further, the step of determining the amount of food in the cooking chamber according to the preset temperature includes: judging whether the difference between the first maximum temperature and the first minimum temperature is less than the first preset value; if the judgment result is yes, determining the amount of food to be the first amount of food; if the judgment result is no, determining the amount of food to be the second amount of food; wherein, the first amount of food is less than the second amount of food.

[0020] In this technical solution, after the first maximum temperature within the first time period and the first minimum temperature within the second time period are determined, the amount of food in the cooking chamber can be determined based on the first maximum temperature and the first minimum temperature. Specifically, the first maximum temperature is first subtracted from the first minimum temperature to obtain a difference between the first maximum temperature and the first minimum temperature. This difference is then compared with a first preset value. If the difference is less than the first preset value, the amount of food in the cooking chamber can be determined to be the first amount of food. If the difference is greater than the first preset value, the amount of food in the cooking chamber can be determined to be the second amount of food.

[0021] Specifically, the first amount of food is smaller than the second amount of food; that is, the first amount of food is the smaller amount, while the second amount of food is the larger amount. It is understood that if the amount of food in the cooking cavity is smaller, the temperature of the bottom of the cooking cavity changes more rapidly during heating. During the transition from the heating device stopping heating to the heating device starting heating, the temperature of the bottom of the cooking cavity rises again before it reaches the lower temperature. Therefore, the difference between the first maximum temperature and the first minimum temperature is not significant. Conversely, if the amount of food in the cooking cavity is larger, the temperature of the bottom of the cooking cavity changes more slowly during heating. During the transition from the heating device stopping heating to the heating device starting heating, the temperature of the bottom of the cooking cavity drops more significantly. Therefore, the difference between the first maximum temperature and the first minimum temperature is larger. In other words, the first amount of food is smaller than the second amount of food.

[0022] Furthermore, when it is determined that the amount of food in the cooking cavity is a first amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the first amount of food, that is, with the operating parameters corresponding to a smaller amount of food; when it is determined that the amount of food in the cooking cavity is a second amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the second amount of food, that is, with the operating parameters corresponding to a larger amount of food, so as to ensure the cooking effect of the cooking appliance.

[0023] In any of the above technical solutions, the cooking cavity is further heated for a second period of time, including: controlling the cooking appliance to heat the cooking cavity at a first preset power, and obtaining the temperature of the bottom of the cooking cavity until the temperature of the bottom of the cooking cavity reaches a second temperature threshold.

[0024] In this technical solution, when the temperature at the bottom of the cooking cavity reaches a first temperature threshold, heating of the cooking cavity is stopped and continued for a first time period. When the heating device has not heated the cooking cavity for the first time period, the heating device is turned on to heat the cooking cavity, and the temperature of the bottom of the cooking cavity is detected in real time by a temperature detector until the temperature of the bottom of the cooking cavity reaches a second temperature threshold. The time period from the start of heating of the cooking cavity by the heating device to the time the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time period. During the second time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature within the preset time period of the second time period, i.e., the first minimum temperature. Furthermore, the amount of food in the cooking cavity is determined based on the first maximum and first minimum temperatures, ensuring the accuracy of the determination of the amount of food in the cooking cavity. The cooking appliance parameters can then be controlled based on the amount of food in the cooking cavity, improving the cooking effect of the cooking appliance and enhancing the user experience.

[0025] Specifically, the first preset power may be any value between half of the rated power and the rated power of the cooking appliance.

[0026] In any of the above technical solutions, further, the step of obtaining a preset temperature of the bottom of the cooking cavity within a preset time period also includes: based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold, stopping heating the cooking cavity and continuing for a third time period; obtaining the second highest temperature of the bottom of the cooking cavity within the third time period; based on the heating stop time reaching the third time period, heating the cooking cavity and continuing for a fourth time period; obtaining the second lowest temperature of the bottom of the cooking cavity within the fourth time period.

[0027] In this technical solution, the preset temperature of the bottom of the cooking cavity in four preset time periods during the operation of the cooking appliance can be obtained, and then the amount of food in the cooking cavity can be judged based on the preset temperatures corresponding to these four preset time periods.

[0028] Specifically, after the cooking appliance starts operating, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to stop operating, that is, to stop heating the cooking cavity, and this stops for a first time period. During the first time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the highest temperature of the bottom of the cooking cavity during the first time period is recorded. This highest temperature is the preset temperature value within the preset time period of the first time period, that is, the first highest temperature. When the time period during which the heating device stops heating the cooking cavity reaches the first time period, the heating device is turned on to heat the cooking cavity through the heating device, and this stops for a second time period. During the second time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded.

[0029] Furthermore, during the second duration, when the temperature at the bottom of the cooking cavity reaches a second temperature threshold, the heating device is controlled to stop heating the cooking cavity and continue heating the cooking cavity for a third duration. The first duration is a preset time period during the operation of the cooking appliance. During the third duration, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the highest temperature of the bottom of the cooking cavity during the third duration is recorded. This highest temperature is the preset temperature value within the preset time period of the third duration, i.e., the second highest temperature. It should be noted that after the heating device stops operating, due to the relatively high residual heat of the heating device, the temperature of the bottom of the cooking cavity does not immediately decrease, but continues to increase. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device stops heating is not the highest temperature of the bottom of the cooking cavity during the third duration.

[0030] Furthermore, when the heating device stops heating the cooking cavity for a third time period, the heating device is turned on to heat the cooking cavity for a fourth time period, which is another preset time period during the operation of the cooking appliance. During the fourth time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the fourth time period is recorded. This lowest temperature is the corresponding preset temperature during the preset time period of the fourth time period, i.e., the second lowest temperature. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately increase, but instead continues to decrease. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device begins heating is not the lowest temperature of the bottom of the cooking cavity during the fourth time period.

[0031] Furthermore, the amount of food in the cooking cavity is determined by the first maximum temperature, the first minimum temperature, the second maximum temperature and the second minimum temperature, thereby further improving the accuracy of the judgment of the amount of food in the cooking cavity, ensuring the cooking effect of the food and improving the user experience.

[0032] In any of the above technical solutions, further, the step of determining the amount of food in the cooking chamber according to the preset temperature includes: determining the difference between the second highest temperature and the second lowest temperature based on the difference between the first highest temperature and the first lowest temperature being greater than or equal to the first preset value; and determining the amount of food according to the difference between the second highest temperature and the second lowest temperature.

[0033] In this technical solution, when the amount of food in the cooking cavity is determined to be the second amount of food by the first maximum temperature and the first minimum temperature, the amount of food in the cooking cavity can be further judged by the second maximum temperature and the second minimum temperature to improve the accuracy of the judgment of the amount of food in the cooking cavity.

[0034] Specifically, when the difference between the first maximum temperature and the first minimum temperature is greater than the first preset value, it can be determined that the current amount of food in the cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second maximum temperature and the second minimum temperature. Then, the amount of food in the cooking cavity is further determined based on the difference between the second maximum temperature and the second minimum temperature.

[0035] In any of the above technical solutions, further, the step of determining the amount of food based on the difference between the second highest temperature and the second lowest temperature includes: judging whether the difference between the second highest temperature and the second lowest temperature is less than a second preset value; if the judgment result is yes, determining the amount of food to be a third amount of food; if the judgment result is no, determining the amount of food to be a fourth amount of food; wherein, the third amount of food is less than the fourth amount of food.

[0036] In this technical solution, when the amount of food in the cooking cavity is determined to be the second amount of food by the first maximum temperature and the first minimum temperature, the amount of food in the cooking cavity can be further judged by the second maximum temperature and the second minimum temperature to improve the accuracy of the judgment of the amount of food in the cooking cavity.

[0037] Specifically, when the difference between the first maximum temperature and the first minimum temperature is greater than the first preset value, it can be determined that the amount of food in the current cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second maximum temperature and the second minimum temperature, and then the difference is compared with the second preset value. If the difference is less than the second preset value, it can be determined that the amount of food in the current cooking cavity is the third amount of food. If the difference is greater than the second preset value, it can be determined that the amount of food in the current cooking cavity is the fourth amount of food.

[0038] Specifically, the third amount of food is smaller than the fourth amount of food. That is, relative to the first amount of food, the third amount of food is a medium amount, while the fourth amount of food is a large amount. It is understandable that if the amount of food in the cooking chamber is small, the temperature of the bottom of the cooking chamber changes more rapidly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking chamber rises again before it reaches a lower temperature. Therefore, the difference between the second highest temperature and the second lowest temperature is not significant. Conversely, if the amount of food in the cooking chamber is large, the temperature of the bottom of the cooking chamber changes more slowly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking chamber drops more significantly. Consequently, the difference between the second highest temperature and the second lowest temperature is larger. Therefore, the third amount of food is smaller than the fourth amount of food.

[0039] Furthermore, when it is determined that the amount of food in the cooking cavity is the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when it is determined that the amount of food in the cooking cavity is the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.

[0040] In any of the above technical solutions, further, heating the cooking cavity for a fourth time period includes: controlling the cooking appliance to heat the cooking cavity at a second preset power for a fourth time period.

[0041] In this technical solution, when the temperature at the bottom of the cooking cavity reaches a second temperature threshold, heating of the cooking cavity is stopped and continued for a third time period. When the time for which the heating device stops heating the cooking cavity reaches the third time period, the heating device is turned on, and the cooking cavity is heated by the heating device to keep the cooking utensil heated at a second preset power for a fourth time period. At the same time, the temperature of the bottom of the cooking utensil is detected in real time within the fourth time period to obtain the second lowest temperature within the fourth time period.

[0042] Specifically, the second preset power can be any value between one sixteenth of the rated power of the cooking appliance and the rated power. Furthermore, the second preset power can be lower than the first preset power to prevent the food in the cooking cavity from being burnt due to excessive heating speed.

[0043] In any of the above technical solutions, further, before the step of obtaining the preset temperature of the bottom of the cooking cavity within the preset time period, the method further includes: controlling the cooking appliance to heat the cooking cavity at a third preset power.

[0044] In this technical solution, when cooking starts, the cooking appliance can be controlled to operate at a third preset power to heat the cooking cavity, and the temperature of the bottom of the cooking cavity can be obtained in real time through the temperature detection element; when the temperature of the bottom of the cooking cavity reaches the first temperature threshold, the heating device is controlled to stop operating, that is, the heating of the cooking cavity is stopped.

[0045] Specifically, the third preset power can be any value between half the rated power of the cooking appliance and the rated power. Furthermore, the third preset power can be greater than or equal to the first preset power to ensure heating efficiency of the cooking appliance and ensure that the temperature at the bottom of the cooking cavity rises quickly and effectively to the first temperature threshold, thereby facilitating determination of the amount of food in the cooking cavity.

[0046] In any of the above technical solutions, the method for controlling the cooking appliance further includes: controlling the operating parameters of the cooking appliance according to the amount of food.

[0047] In this technical solution, by obtaining the preset temperatures corresponding to the four preset time periods during the operation of the cooking appliance, the amount of food in the cooking chamber can be accurately judged. Furthermore, the cooking appliance is controlled to operate with corresponding operating parameters according to the amount of food in the cooking chamber, which can ensure the cooking effect of the food and avoid the phenomenon of the food being burnt or not fully cooked. The user does not need to detect the cooking process, which facilitates the user's operation and improves the user experience.

[0048] Specifically, when the amount of food in the cooking cavity is determined to be the first amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the first amount of food, that is, with the operating parameters corresponding to the smaller amount of food; when the amount of food in the cooking cavity is determined to be the second amount of food through the first maximum temperature and the first minimum temperature, the amount of food in the cooking cavity can be further judged through the second maximum temperature and the second minimum temperature. When the amount of food in the cooking cavity is determined to be the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when the amount of food in the cooking cavity is determined to be the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.

[0049] According to a second aspect of the present invention, a control device for a cooking appliance is provided, comprising: an acquisition unit for acquiring a preset temperature at the bottom of a cooking cavity within a preset time period; and a determination unit for determining the amount of food in the cooking cavity according to the preset temperature.

[0050] The control device for a cooking appliance provided by the present invention first obtains, through an acquisition unit, a preset time period during the operation of the cooking appliance after the cooking appliance starts operating, and the preset time period may be at least two; then, a preset temperature at the bottom of the cooking cavity is determined within each preset time period; finally, the determination unit determines the amount of food in the cooking cavity based on the corresponding preset temperature obtained within each preset time period, thereby achieving the determination of the amount of food in the cooking cavity.

[0051] Specifically, the ingredients in the cooking cavity can be rice, millet or other rice ingredients. During the cooking process, the cooking appliance can obtain a preset temperature within at least one preset time period through the acquisition unit, and then the determination unit can determine the amount of rice in the cooking cavity according to the preset temperature, so as to control the operating parameters of the cooking appliance according to the amount of rice, thereby avoiding the phenomenon that the cooked rice is undercooked, the bottom is mushy or too thin, and ensuring the cooking effect.

[0052] Specifically, the acquisition unit may be a temperature detection element, and the temperature detection element is provided at the bottom of the cooking cavity, for detecting the temperature of the bottom of the cooking cavity.

[0053] The control method of the cooking appliance provided by the present invention detects the temperature of the bottom of the cooking cavity during the operation of the cooking appliance, so as to detect the temperature of the food in direct contact with the bottom of the cooking cavity, thereby avoiding that the temperature is too high and causes the food to become mushy, or the temperature is too low and cannot be effectively cooked. Furthermore, the preset temperature of the bottom of the cooking cavity within a preset time period is obtained by the acquisition unit, so that the determination unit can determine the amount of food in the cooking cavity according to the temperature of the bottom of the cooking cavity within the preset time period, so that the cooking appliance can adjust the corresponding operating parameters according to the amount of food in the cooking cavity, thereby improving the cooking effect of the cooking appliance and improving the user experience.

[0054] Furthermore, the acquisition unit is specifically used to: obtain the temperature of the bottom of the cooking cavity; based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stop heating the cooking cavity and continue for a first time period; obtain the first maximum temperature of the bottom of the cooking cavity within the first time period; based on the time period for stopping heating reaching the first time period, heat the cooking cavity and continue for a second time period; obtain the first minimum temperature of the bottom of the cooking cavity within the second time period.

[0056] Furthermore, the control device of the cooking appliance also includes a control unit, which is specifically used to: control the cooking appliance to heat the cooking cavity at a first preset power and obtain the temperature of the bottom of the cooking cavity until the temperature of the bottom of the cooking cavity reaches a second temperature threshold.

[0057] Furthermore, the control unit is specifically used to: stop heating the cooking cavity and continue for a third time period based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold; the acquisition unit is specifically used to: obtain the second highest temperature of the bottom of the cooking cavity within the third time period; heat the cooking cavity and continue for a fourth time period based on the heating stop time reaching the third time period; and obtain the second lowest temperature of the bottom of the cooking cavity within the fourth time period.

[0058] Furthermore, the determination unit is specifically used to: determine the difference between the second maximum temperature and the second minimum temperature based on the difference between the first maximum temperature and the first minimum temperature being greater than or equal to a first preset value; and determine the amount of food according to the difference between the second maximum temperature and the second minimum temperature.

[0059] Furthermore, the determination unit is specifically used to: determine whether the difference between the second highest temperature and the second lowest temperature is less than a second preset value; if the judgment result is yes, determine the food amount to be the third food amount; if the judgment result is no, determine the food amount to be the fourth food amount; wherein the third food amount is less than the fourth food amount.

[0060] Furthermore, the control unit is specifically configured to control the cooking appliance to heat the cooking cavity at a second preset power for a fourth duration.

[0061] Furthermore, the control unit is further configured to: before the step of obtaining the preset temperature of the bottom of the cooking cavity within the preset time period, control the cooking appliance to heat the cooking cavity at a third preset power.

[0062] Furthermore, the control unit is specifically configured to control operating parameters of the cooking appliance according to the amount of food.

[0086] The control method of the cooking appliance provided by the present invention first obtains a preset time period during the operation of the cooking appliance after the cooking appliance starts operating, and the preset time period can be at least two; then, a preset temperature of the bottom of the cooking cavity is obtained in each preset time period; finally, the amount of food in the cooking cavity is determined based on the corresponding preset temperature obtained in each preset time period, thereby achieving the determination of the amount of food in the cooking cavity.

[0087] Specifically, the ingredients in the cooking cavity can be rice, millet or other rice ingredients. During the cooking process, the cooking appliance can obtain a preset temperature within at least one preset time period and determine the amount of rice in the cooking cavity according to the preset temperature. Therefore, the operating parameters of the cooking appliance can be controlled according to the amount of rice, thereby avoiding the phenomenon that the cooked rice is undercooked, the bottom is mushy or too watery, and ensuring the cooking effect.

[0088] Specifically, the cooking appliance may be provided with a temperature detection element, and the temperature detection element is provided at the bottom of the cooking cavity for detecting the temperature of the bottom of the cooking cavity.

[0089] The control method of the cooking appliance provided by the present invention detects the temperature of the bottom of the cooking cavity during the operation of the cooking appliance, so as to detect the temperature of the food in direct contact with the bottom of the cooking cavity, thereby preventing the food from being mushy due to excessively high temperature, or from being unable to be effectively cooked due to excessively low temperature. Furthermore, by obtaining the preset temperature of the bottom of the cooking cavity within a preset time period, the amount of food in the cooking cavity can be determined according to the temperature of the bottom of the cooking cavity within the preset time period, so that the cooking appliance can adjust the corresponding operating parameters according to the amount of food in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0090] According to one embodiment of the present invention, Figure 2 As shown, a control method for a cooking appliance is proposed, the method comprising:

[0091] Step S202: acquiring the temperature of the bottom of the cooking cavity based on the cooking appliance starting to operate;

[0092] Step S204, based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stopping heating the cooking cavity and continuing for a first time period;

[0093] Step S206, obtaining a first maximum temperature of the bottom of the cooking cavity within a first time period;

[0094] Step S208, heating the cooking cavity for a second time period based on the heating stop time period reaching the first time period;

[0095] Step S210, obtaining the first lowest temperature of the bottom of the cooking cavity within the second time period;

[0096] Step S212, determining whether the difference between the first maximum temperature and the first minimum temperature is less than a first preset value; if so, executing step S214, if not, executing step S216;

[0097] Step S214, determining the amount of food to be the first amount of food;

[0098] Step S216: Determine the amount of food to be the second amount of food.

[0099] In this embodiment, the preset temperatures of the bottom of the cooking cavity in two preset time periods during the operation of the cooking appliance can be obtained, and then the amount of food in the cooking cavity can be judged based on the preset temperatures corresponding to the two preset time periods.

[0100] Specifically, if Figure 6 and Figure 7As shown, after the cooking appliance begins operating, the heating device may begin heating the cooking cavity and, via a temperature sensor, detect the temperature of the bottom of the cooking cavity in real time. When the temperature of the bottom of the cooking cavity reaches a first temperature threshold A, the heating device is controlled to stop operating, i.e., to stop heating the cooking cavity, for a first duration, which is a preset time period during the operation of the cooking appliance. During the first duration, the temperature of the bottom of the cooking cavity continues to be detected via the temperature sensor, and the highest temperature of the bottom of the cooking cavity during the first duration is recorded. This highest temperature is the preset temperature value within the first preset time period, i.e., the first highest temperature B. It should be noted that, after the heating device stops operating, the temperature of the bottom of the cooking cavity does not immediately decrease, but instead continues to increase, due to the relatively high residual heat of the heating device. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device stops heating is not the highest temperature of the bottom of the cooking cavity during the first duration.

[0101] Specifically, the first temperature threshold can be set to between 60 degrees Celsius and 110 degrees Celsius, and the first time length can be set to between 10 seconds and 5 minutes.

[0102] Furthermore, when the heating device stops heating the cooking cavity for a first time period, the heating device is turned on to heat the cooking cavity for a second time period, which is another preset time period during the operation of the cooking appliance. During the second time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detection element, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature during the second preset time period, i.e., the first lowest temperature C. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately rise, but instead continues to fall. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device begins heating is not the lowest temperature of the bottom of the cooking cavity during the second time period.

[0103] The amount of food in the cooking cavity is determined by the first maximum temperature and the first minimum temperature, thereby ensuring the accuracy of the determination of the amount of food in the cooking cavity. Then, the parameters of the cooking appliance can be controlled according to the amount of food in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0104] Furthermore, after the first maximum temperature during the first duration and the first minimum temperature during the second duration are determined, the amount of food in the cooking chamber can be determined based on the first maximum temperature and the first minimum temperature. Specifically, the first maximum temperature is first subtracted from the first minimum temperature to obtain a difference between the first minimum temperature and the first maximum temperature. This difference is then compared with a first preset value. If the difference is less than the first preset value, the amount of food in the cooking chamber can be determined to be the first amount of food. If the difference is greater than the first preset value, the amount of food in the cooking chamber can be determined to be the second amount of food.

[0105] Specifically, the first maximum temperature is between 60 degrees Celsius and 110 degrees Celsius, and the first minimum temperature is between 40 degrees Celsius and 110 degrees Celsius.

[0106] Specifically, the second amount of food is greater than the first amount of food; that is, the first amount of food is the smaller amount, and the second amount of food is the larger amount. It will be understood that if the amount of food in the cooking cavity is smaller, the temperature of the bottom of the cooking cavity changes more rapidly during the heating process. During the transition from the heating device stopping heating to the heating device starting heating, the temperature of the bottom of the cooking cavity rises again before it reaches the lower temperature. Therefore, the difference between the first maximum temperature and the first minimum temperature is not significant. Conversely, if the amount of food in the cooking cavity is larger, the temperature of the bottom of the cooking cavity changes more slowly during the heating process. During the transition from the heating device stopping heating to the heating device starting heating, the temperature of the bottom of the cooking cavity drops more significantly. Therefore, the difference between the first minimum temperature and the first maximum temperature is larger. In other words, the second amount of food is greater than the first amount of food.

[0107] Furthermore, when it is determined that the amount of food contained in the cooking cavity is a first amount of food, the cooking appliance can be controlled to operate with operating parameters corresponding to the first amount of food, that is, with operating parameters corresponding to a smaller amount of food; when it is determined that the amount of food contained in the cooking cavity is a second amount of food, the cooking appliance is controlled to operate with operating parameters corresponding to the second amount of food, that is, with operating parameters corresponding to a larger amount of food, so as to ensure the cooking effect of the cooking appliance.

[0108] Furthermore, the cooking cavity is heated for a second period of time, including: controlling the cooking appliance to heat the cooking cavity at a first preset power, and obtaining the temperature of the bottom of the cooking cavity until the temperature of the bottom of the cooking cavity reaches a second temperature threshold.

[0109] Specifically, when the temperature at the bottom of the cooking cavity reaches a first temperature threshold, heating of the cooking cavity is stopped and continued for a first time period. When the heating device has not heated the cooking cavity for the first time period, the heating device is turned on to heat the cooking cavity, and the temperature of the bottom of the cooking cavity is detected in real time by the temperature detector until the temperature of the bottom of the cooking cavity reaches a second temperature threshold. The time period from when the heating device starts heating the cooking cavity to when the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time period. During the second time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature within the preset time period of the second time period, i.e., the first minimum temperature. Furthermore, the amount of food contained in the cooking cavity is determined based on the first minimum temperature and the first maximum temperature, ensuring the accuracy of the determination of the amount of food contained in the cooking cavity. The cooking appliance parameters can then be controlled based on the amount of food contained in the cooking cavity, improving the cooking effect of the cooking appliance and enhancing the user experience.

[0110] Specifically, the first preset power may be any value between half of the rated power and the rated power of the cooking appliance.

[0111] According to one embodiment of the present invention, Figure 3 As shown, a control method for a cooking appliance is proposed, the method comprising:

[0112] Step S302: acquiring the temperature of the bottom of the cooking cavity based on the cooking appliance starting to operate;

[0113] Step S304: based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stopping heating the cooking cavity and continuing for a first time period;

[0114] Step S306, obtaining the first maximum temperature of the bottom of the cooking cavity within the first time period;

[0115] Step S308, heating the cooking cavity for a second time period based on the heating stop time period reaching the first time period;

[0116] Step S310, obtaining the first lowest temperature of the bottom of the cooking cavity within the second time period;

[0117] Step S312: based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold, stopping heating the cooking cavity and continuing heating for a third time period;

[0118] Step S314, obtaining the second highest temperature of the bottom of the cooking cavity within the third time period; heating the cooking cavity for a fourth time period based on the heating stop time period reaching the third time period;

[0119] Step S316, obtaining the second lowest temperature of the bottom of the cooking cavity within the fourth time period;

[0120] Step S318, determining whether the difference between the first maximum temperature and the first minimum temperature is less than a first preset value; if so, executing step S320, if not, executing step S322;

[0121] Step S320, determining the amount of food to be the first amount of food;

[0122] Step S322: Determine the amount of food to be the second amount of food.

[0123] Step S324 , determining whether the difference between the second highest temperature and the second lowest temperature is less than a second preset value; if so, executing step S326 , if not, executing step S328 .

[0124] Step S326, determining the amount of the ingredient to be the third ingredient amount;

[0125] Step S328: Determine the amount of food to be the fourth amount of food.

[0126] In this embodiment, the preset temperatures at the bottom of the cooking cavity during four preset time periods during the operation of the cooking appliance can be obtained, and the amount of food contained in the cooking cavity can be judged based on the preset temperatures corresponding to the four preset time periods.

[0127] Specifically, if Figure 6 and Figure 7 As shown, after the cooking appliance starts operating, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold A, the heating device is controlled to stop operating, that is, to stop heating the cooking cavity, and this stops for a first time period. During the first time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the highest temperature of the bottom of the cooking cavity during the first time period is recorded. This highest temperature is the preset temperature value within the preset time period corresponding to the first time period, that is, the first highest temperature B. When the heating device stops heating the cooking cavity for the first time period, the heating device is turned on to heat the cooking cavity for a second time period. During the second time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the first lowest temperature C of the bottom of the cooking cavity during the second time period is recorded.

[0128] Furthermore, during the second duration, when the temperature of the bottom of the cooking cavity reaches a second temperature threshold D, the heating device is controlled to stop heating the cooking cavity and continue heating the cooking cavity for a third duration. The first duration is a preset time period during the operation of the cooking appliance. During the third duration, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detection element, and the highest temperature of the bottom of the cooking cavity during the third duration is recorded. This highest temperature is the preset temperature value within the preset time period of the third duration, i.e., the second highest temperature E. It should be noted that after the heating device stops operating, the temperature of the bottom of the cooking cavity does not immediately decrease, but continues to increase, due to the relatively high residual heat of the heating device. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device stops heating is not the highest temperature of the bottom of the cooking cavity during the third duration.

[0129] Specifically, the second temperature threshold can be set to 80 degrees Celsius to 120 degrees Celsius, and the third time length can be set to 10 seconds to 5 minutes.

[0130] Furthermore, when the heating device stops heating the cooking cavity for a third time period, the heating device is turned on to heat the cooking cavity for a fourth time period, which is another preset time period during the operation of the cooking appliance. During the fourth time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detecting element, and the lowest temperature of the bottom of the cooking cavity during the fourth time period is recorded. This lowest temperature is the corresponding preset temperature during the fourth time period, i.e., the second lowest temperature F. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately rise, but instead continues to fall. Therefore, when the heating device begins heating, the temperature of the bottom of the cooking cavity is not the lowest temperature of the bottom of the cooking cavity during the fourth time period.

[0131] Specifically, the second highest temperature is 80 degrees Celsius to 120 degrees Celsius, the second lowest temperature is 60 degrees Celsius to 120 degrees Celsius, and the fourth time length is 10 seconds to 5 minutes.

[0132] Furthermore, the amount of food contained in the cooking cavity is determined by the first maximum temperature, the first minimum temperature, the second maximum temperature and the second minimum temperature, thereby further improving the accuracy of the judgment of the amount of food contained in the cooking cavity, ensuring the cooking effect of the food, and improving the user experience.

[0133] Furthermore, when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature to improve the accuracy of the judgment of the amount of food contained in the cooking cavity.

[0134] Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than the first preset value, it can be determined that the amount of food currently contained in the cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second minimum temperature and the second maximum temperature. Then, the amount of food contained in the cooking cavity is further determined based on the difference between the second minimum temperature and the second maximum temperature.

[0135] Furthermore, when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature to improve the accuracy of the judgment of the amount of food contained in the cooking cavity.

[0136] Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than the first preset value, it can be determined that the amount of food currently contained in the cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second minimum temperature and the second maximum temperature, and then the difference is compared with the second preset value. If the difference is less than the second preset value, it can be determined that the amount of food currently contained in the cooking cavity is the third amount of food. If the difference is greater than the second preset value, it can be determined that the amount of food currently contained in the cooking cavity is the fourth amount of food.

[0137] Specifically, the third ingredient amount is smaller than the fourth ingredient amount. That is, relative to the first ingredient amount, the third ingredient amount is a medium amount, while the fourth ingredient amount is a large amount. It is understood that if the amount of food in the cooking cavity is small, the temperature of the bottom of the cooking cavity changes more rapidly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking cavity rises again before it reaches a lower temperature. Therefore, the difference between the second highest temperature and the second lowest temperature is not significant. Conversely, if the amount of food in the cooking cavity is large, the temperature of the bottom of the cooking cavity changes more slowly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking cavity drops more significantly. Consequently, the difference between the second lowest temperature and the second highest temperature is larger. Therefore, the third ingredient amount is smaller than the fourth ingredient amount.

[0138] Furthermore, when it is determined that the amount of food contained in the cooking cavity is the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when it is determined that the amount of food contained in the cooking cavity is the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.

[0139] Furthermore, heating the cooking cavity for a fourth time period includes: controlling the cooking appliance to heat the cooking cavity at a second preset power for the fourth time period.

[0140] Specifically, when the temperature at the bottom of the cooking cavity reaches a second temperature threshold, heating of the cooking cavity is stopped and continued for a third time period. When the time for which the heating device stops heating the cooking cavity reaches the third time period, the heating device is turned on, and the cooking cavity is heated by the heating device to maintain heating of the cooking utensil at a second preset power for a fourth time period. At the same time, the temperature of the bottom of the cooking utensil is detected in real time during the fourth time period to obtain the second lowest temperature during the fourth time period.

[0141] Specifically, the second preset power can be any value between one sixteenth of the rated power of the cooking appliance and the rated power. Furthermore, the second preset power can be lower than the first preset power to prevent the food in the cooking cavity from being burnt due to excessive heating.

[0142] According to one embodiment of the present invention, Figure 4 As shown, a control method for a cooking appliance is proposed, the method comprising:

[0143] Step S402, controlling the cooking appliance to heat the cooking cavity at a third preset power;

[0144] Step S404: acquiring the temperature of the bottom of the cooking cavity based on the cooking appliance starting to operate;

[0145] Step S406, based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stopping heating the cooking cavity and continuing for a first time period;

[0146] Step S408, obtaining the first maximum temperature of the bottom of the cooking cavity within the first time period;

[0147] Step S410, heating the cooking cavity for a second time period based on the heating stop time period reaching the first time period;

[0148] Step S412, obtaining the first lowest temperature of the bottom of the cooking cavity within the second time period;

[0149] Step S414: based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold, stopping heating the cooking cavity and continuing heating for a third time period;

[0150] Step S416, obtaining the second highest temperature of the bottom of the cooking cavity within the third time period; heating the cooking cavity for a fourth time period based on the heating stop time period reaching the third time period;

[0151] Step S418, obtaining the second lowest temperature of the bottom of the cooking cavity within the fourth time period;

[0152] Step S420, determining whether the difference between the first maximum temperature and the first minimum temperature is less than a first preset value; if so, executing step S422, if not, executing step S424;

[0153] Step S422, determining the amount of food to be the first amount of food;

[0154] Step S424: determine that the amount of food is the second amount of food.

[0155] Step S426, determining whether the difference between the second highest temperature and the second lowest temperature is less than a second preset value; if so, executing step S428, if not, executing step S430.

[0156] Step S428, determining the amount of the ingredient to be the third ingredient amount;

[0157] Step S430: Determine the amount of food as the fourth amount of food.

[0158] In this embodiment, when cooking starts, the cooking appliance can be controlled to operate at a third preset power to heat the cooking cavity, and the temperature of the bottom of the cooking cavity can be obtained in real time through the temperature detection element; when the temperature of the bottom of the cooking cavity reaches the first temperature threshold, the heating device is controlled to stop operating, that is, the heating of the cooking cavity is stopped.

[0159] Specifically, the third preset power can be any value between half the rated power of the cooking appliance and the rated power. Furthermore, the third preset power can be greater than or equal to the first preset power to ensure heating efficiency of the cooking appliance and ensure that the temperature at the bottom of the cooking cavity quickly and effectively rises to the first temperature threshold, thereby facilitating determination of the amount of food contained in the cooking cavity.

[0160] According to one embodiment of the present invention, Figure 5 As shown, a control method for a cooking appliance is proposed, the method comprising:

[0161] Step S502, controlling the cooking appliance to heat the cooking cavity at a third preset power;

[0162] Step S504: acquiring the temperature of the bottom of the cooking cavity based on the cooking appliance starting to operate;

[0163] Step S506, based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, stopping heating the cooking cavity and continuing for a first time period;

[0164] Step S508, obtaining the first maximum temperature of the bottom of the cooking cavity within the first time period;

[0165] Step S510, heating the cooking cavity for a second time period based on the heating stop time period reaching the first time period;

[0166] Step S512, obtaining the first lowest temperature of the bottom of the cooking cavity within the second time period;

[0167] Step S514: based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold, stopping heating the cooking cavity and continuing for a third time period;

[0168] Step S516, obtaining the second highest temperature of the bottom of the cooking cavity within the third time period; heating the cooking cavity for a fourth time period based on the heating stop time period reaching the third time period;

[0169] Step S518, obtaining the second lowest temperature of the bottom of the cooking cavity within the fourth time period;

[0170] Step S520, determining whether the difference between the first maximum temperature and the first minimum temperature is less than a first preset value; if so, executing step S522, if not, executing step S524;

[0171] Step S522, determining the amount of food to be the first amount of food;

[0172] Step S524: determine that the amount of food is the second amount of food.

[0173] Step S526, determining whether the difference between the second highest temperature and the second lowest temperature is less than a second preset value; if so, executing step S528, if not, executing step S530.

[0174] Step S528, determining the amount of the ingredient to be the third ingredient amount;

[0175] Step S530, determining the amount of the food to be the fourth food amount;

[0176] Step S530: Control the operating parameters of the cooking appliance according to the amount of food.

[0177] In this embodiment, by obtaining the preset temperatures corresponding to the four preset time periods during the operation of the cooking appliance, accurate judgment of the amount of food contained in the cooking cavity is achieved. Furthermore, the cooking appliance is controlled to operate with corresponding operating parameters according to the amount of food contained in the cooking cavity, which can ensure the cooking effect of the food and avoid the phenomenon of the food being burnt or not fully cooked. The user does not need to detect the cooking process, which facilitates the user's operation and improves the user experience.

[0178] Specifically, when it is determined that the amount of food contained in the cooking cavity is the first amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the first amount of food, that is, with the operating parameters corresponding to the smaller amount of food; when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature. When it is determined that the amount of food contained in the cooking cavity is the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when it is determined that the amount of food contained in the cooking cavity is the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.

[0179] According to a second aspect of the present invention, a control device for a cooking appliance is provided, comprising: an acquisition unit for acquiring a preset temperature at the bottom of a cooking cavity within a preset time period; and a determination unit for determining the amount of food contained in the cooking cavity according to the preset temperature.

[0180] The control device for a cooking appliance provided by the present invention first obtains, through an acquisition unit, a preset time period during the operation of the cooking appliance after the cooking appliance starts operating, and the preset time period may be at least two; then, a preset temperature of the bottom of the cooking cavity is determined within each preset time period; finally, the determination unit determines the amount of food contained in the cooking cavity based on the corresponding preset temperature obtained in each preset time period, thereby determining the amount of food contained in the cooking cavity.

[0181] Specifically, the ingredients placed in the cooking cavity can be rice, millet or other rice ingredients. During the cooking process, the cooking appliance can obtain a preset temperature within at least one preset time period through the acquisition unit, and then the determination unit can determine the amount of rice in the cooking cavity according to the preset temperature, so as to control the operating parameters of the cooking appliance according to the amount of rice, thereby avoiding the phenomenon that the cooked rice is undercooked, the bottom is mushy or too thin, and ensuring the cooking effect.

[0182] Specifically, the acquisition unit may be a temperature detection element, and the temperature detection element is provided at the bottom of the cooking cavity, for detecting the temperature of the bottom of the cooking cavity.

[0183] The control method of the cooking appliance provided by the present invention detects the temperature of the bottom of the cooking cavity during the operation of the cooking appliance, so as to detect the temperature of the food in direct contact with the bottom of the cooking cavity, thereby avoiding that the food will be scorched due to excessively high temperature, or that the food cannot be effectively cooked due to excessively low temperature. Furthermore, the preset temperature of the bottom of the cooking cavity within a preset time period is obtained by the acquisition unit, so that the determination unit can determine the amount of food contained in the cooking cavity according to the temperature of the bottom of the cooking cavity within the preset time period, so that the cooking appliance can adjust the corresponding operating parameters according to the amount of food contained in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0184] Furthermore, by obtaining the preset temperatures of the bottom of the cooking cavity in two preset time periods during the operation of the cooking appliance, the amount of food contained in the cooking cavity is judged according to the preset temperatures corresponding to the two preset time periods.

[0185] Specifically, after the cooking appliance begins operating, the heating device may begin heating the cooking cavity and, via a temperature sensor, detect the temperature of the bottom of the cooking cavity in real time. When the temperature of the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to cease operation, thereby stopping heating the cooking cavity, and this process continues for a first duration, which is a preset time period during the operation of the cooking appliance. During the first duration, the temperature of the bottom of the cooking cavity continues to be detected via the temperature sensor, and the highest temperature of the bottom of the cooking cavity during the first duration is recorded. This highest temperature is the preset temperature value within the first preset time period, i.e., the first highest temperature. It should be noted that, after the heating device ceases operation, the temperature of the bottom of the cooking cavity does not immediately decrease, but instead continues to increase, due to the relatively high residual heat of the heating device. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device ceases heating is not the highest temperature of the bottom of the cooking cavity during the first duration.

[0186] Furthermore, when the heating device stops heating the cooking cavity for a first time period, the heating device is turned on to heat the cooking cavity for a second time period, which is another preset time period during the operation of the cooking appliance. During the second time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature during the second preset time period, i.e., the first lowest temperature. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately increase, but instead continues to decrease. Therefore, when the heating device begins heating, the temperature of the bottom of the cooking cavity is not the lowest temperature of the bottom of the cooking cavity during the second time period.

[0187] Furthermore, the amount of food contained in the cooking cavity is determined by the first minimum temperature and the first maximum temperature, thereby ensuring the accuracy of the amount of food contained in the cooking cavity. Then, the parameters of the cooking appliance can be controlled according to the amount of food contained in the cooking cavity, thereby improving the cooking effect of the cooking appliance and enhancing the user experience.

[0188] Furthermore, after the first maximum temperature during the first duration and the first minimum temperature during the second duration are determined, the amount of food contained in the cooking cavity can be determined based on the first maximum temperature and the first minimum temperature. Specifically, the first maximum temperature is first subtracted from the first minimum temperature to obtain a difference between the first minimum temperature and the first maximum temperature. This difference is then compared with a first preset value. If the difference is less than the first preset value, the amount of food contained in the cooking cavity can be determined to be the first amount of food. If the difference is greater than the first preset value, the amount of food contained in the cooking cavity can be determined to be the second amount of food.

[0189] Specifically, the second amount of food is greater than the first amount of food; that is, the first amount of food is a smaller amount, and the second amount of food is a larger amount. It will be understood that if the amount of food contained in the cooking cavity is smaller, the temperature of the bottom of the cooking cavity will change more rapidly during the heating process. During the transition from the heating device stopping heating to the heating device restarting heating, the temperature of the bottom of the cooking cavity will rise again before it reaches a lower temperature. Therefore, the difference between the first maximum temperature and the first minimum temperature will not be significant. Conversely, if the amount of food contained in the cooking cavity is larger, the temperature of the bottom of the cooking cavity will change more slowly during the heating process. During the transition from the heating device stopping heating to the heating device restarting heating, the temperature of the bottom of the cooking cavity will drop more significantly. Therefore, the difference between the first minimum temperature and the first maximum temperature will be larger. In other words, the second amount of food is greater than the first amount of food.

[0190] Furthermore, when it is determined that the amount of food contained in the cooking cavity is a first amount of food, the cooking appliance can be controlled to operate with operating parameters corresponding to the first amount of food, that is, with operating parameters corresponding to a smaller amount of food; when it is determined that the amount of food contained in the cooking cavity is a second amount of food, the cooking appliance is controlled to operate with operating parameters corresponding to the second amount of food, that is, with operating parameters corresponding to a larger amount of food, so as to ensure the cooking effect of the cooking appliance.

[0191] Furthermore, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, heating of the cooking cavity is stopped and continued for a first time period. When the heating device has not heated the cooking cavity for the first time period, the heating device is turned on to heat the cooking cavity, and the temperature of the bottom of the cooking cavity is detected in real time by the temperature detector until the temperature of the bottom of the cooking cavity reaches a second temperature threshold. The time from when the heating device starts heating the cooking cavity to when the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time period. During the second time period, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded. This lowest temperature is the corresponding preset temperature within the preset time period of the second time period, i.e., the first lowest temperature. Furthermore, the amount of food contained in the cooking cavity is determined based on the first lowest temperature and the first highest temperature, ensuring the accuracy of the determination of the amount of food contained in the cooking cavity. The cooking appliance parameters can then be controlled based on the amount of food contained in the cooking cavity, improving the cooking effect of the cooking appliance and enhancing the user experience.

[0192] Specifically, the first preset power may be any value between half of the rated power and the rated power of the cooking appliance.

[0193] Furthermore, the preset temperatures of the bottom of the cooking cavity in four preset time periods during the operation of the cooking appliance can be obtained, and then the amount of food contained in the cooking cavity can be judged based on the preset temperatures corresponding to the four preset time periods.

[0194] Specifically, after the cooking appliance starts operating, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to stop operating, that is, to stop heating the cooking cavity, and this stops for a first time period. During the first time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detecting device, and the highest temperature of the bottom of the cooking cavity during the first time period is recorded. This highest temperature is the preset temperature value within the preset time period of the first time period, that is, the first highest temperature. When the heating device stops heating the cooking cavity for the first time period, the heating device is turned on to heat the cooking cavity for a second time period. During the second time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detecting device, and the lowest temperature of the bottom of the cooking cavity during the second time period is recorded.

[0195] Furthermore, during the second duration, when the temperature of the bottom of the cooking cavity reaches a second temperature threshold, the heating device is controlled to stop heating the cooking cavity and continue heating the cooking cavity for a third duration, where the first duration is a preset time period during the operation of the cooking appliance. During the third duration, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detector, and the highest temperature of the bottom of the cooking cavity during the third duration is recorded. This highest temperature is the preset temperature value during the third preset time period, i.e., the second highest temperature. It should be noted that after the heating device stops operating, the temperature of the bottom of the cooking cavity does not immediately decrease due to the relatively high residual heat of the heating device, but instead continues to increase. Therefore, the temperature of the bottom of the cooking cavity at the moment the heating device stops heating is not the highest temperature of the bottom of the cooking cavity during the third duration.

[0196] Furthermore, when the heating device stops heating the cooking cavity for a third time period, the heating device is turned on to heat the cooking cavity for a fourth time period, which is another preset time period during the operation of the cooking appliance. During the fourth time period, the temperature of the bottom of the cooking cavity continues to be detected by the temperature detector, and the lowest temperature of the bottom of the cooking cavity during the fourth time period is recorded. This lowest temperature is the corresponding preset temperature during the fourth time period, i.e., the second lowest temperature. It should be noted that, for a short period of time after the heating device begins operating, because the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity does not immediately increase, but instead continues to decrease. Therefore, when the heating device begins heating, the temperature of the bottom of the cooking cavity is not the lowest temperature of the bottom of the cooking cavity during the fourth time period.

[0197] Furthermore, the amount of food contained in the cooking cavity is determined by the first maximum temperature, the first minimum temperature, the second maximum temperature and the second minimum temperature, thereby further improving the accuracy of the judgment of the amount of food contained in the cooking cavity, ensuring the cooking effect of the food, and improving the user experience.

[0198] Furthermore, when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature to improve the accuracy of the judgment of the amount of food contained in the cooking cavity.

[0199] Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than the first preset value, it can be determined that the amount of food currently contained in the cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second minimum temperature and the second maximum temperature. Then, the amount of food contained in the cooking cavity is further determined based on the difference between the second minimum temperature and the second maximum temperature.

[0200] Furthermore, when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature to improve the accuracy of the judgment of the amount of food contained in the cooking cavity.

[0201] Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than the first preset value, it can be determined that the amount of food currently contained in the cooking cavity is the second amount of food. Further, the second maximum temperature is subtracted from the second minimum temperature to obtain the difference between the second minimum temperature and the second maximum temperature, and then the difference is compared with the second preset value. If the difference is less than the second preset value, it can be determined that the amount of food currently contained in the cooking cavity is the third amount of food. If the difference is greater than the second preset value, it can be determined that the amount of food currently contained in the cooking cavity is the fourth amount of food.

[0202] Specifically, the third ingredient amount is smaller than the fourth ingredient amount. That is, relative to the first ingredient amount, the third ingredient amount is a medium amount, while the fourth ingredient amount is a large amount. It is understood that if the amount of food in the cooking cavity is small, the temperature of the bottom of the cooking cavity changes more rapidly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking cavity rises again before it reaches a lower temperature. Therefore, the difference between the second highest temperature and the second lowest temperature is not significant. Conversely, if the amount of food in the cooking cavity is large, the temperature of the bottom of the cooking cavity changes more slowly during heating. During the transition from the heating device stopping heating to the start-up heating, the temperature of the bottom of the cooking cavity drops more significantly. Consequently, the difference between the second lowest temperature and the second highest temperature is larger. Therefore, the third ingredient amount is smaller than the fourth ingredient amount.

[0203] Furthermore, when it is determined that the amount of food contained in the cooking cavity is the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when it is determined that the amount of food contained in the cooking cavity is the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.

[0204] Furthermore, when the temperature at the bottom of the cooking cavity reaches a second temperature threshold, heating of the cooking cavity is stopped and continued for a third time period. When the time for which the heating device stops heating the cooking cavity reaches the third time period, the heating device is turned on to heat the cooking cavity, and the cooking utensil is kept heated at a second preset power for a fourth time period. At the same time, the temperature of the bottom of the cooking utensil is detected in real time during the fourth time period to obtain the second lowest temperature during the fourth time period.

[0205] Specifically, the second preset power can be any value between one sixteenth of the rated power of the cooking appliance and the rated power. Furthermore, the second preset power can be lower than the first preset power to prevent the food in the cooking cavity from being burnt due to excessive heating.

[0206] Furthermore, when cooking starts, the cooking appliance can be controlled to operate at a third preset power to heat the cooking cavity, and the temperature of the bottom of the cooking cavity can be obtained in real time through the temperature detection component; when the temperature of the bottom of the cooking cavity reaches the first temperature threshold, the heating device is controlled to stop operating, that is, the heating of the cooking cavity is stopped.

[0207] Specifically, the third preset power can be any value between half the rated power of the cooking appliance and the rated power. Furthermore, the third preset power can be greater than or equal to the first preset power to ensure heating efficiency of the cooking appliance and ensure that the temperature at the bottom of the cooking cavity quickly and effectively rises to the first temperature threshold, thereby facilitating determination of the amount of food contained in the cooking cavity.

[0208] Furthermore, by obtaining the preset temperatures corresponding to the four preset time periods during the operation of the cooking appliance, the amount of food placed in the cooking cavity can be accurately judged. Furthermore, the cooking appliance is controlled to operate with corresponding operating parameters according to the amount of food placed in the cooking cavity, which can ensure the cooking effect of the food and avoid the phenomenon of the food being burnt or not fully cooked. The user does not need to detect the cooking process, which facilitates the user's operation and improves the user experience.

[0209] Specifically, when it is determined that the amount of food contained in the cooking cavity is the first amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the first amount of food, that is, with the operating parameters corresponding to the smaller amount of food; when the amount of food contained in the cooking cavity is determined to be the second amount of food through the first minimum temperature and the first maximum temperature, the amount of food contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature. When it is determined that the amount of food contained in the cooking cavity is the third amount of food, the cooking appliance can be controlled to operate with the operating parameters corresponding to the third amount of food, that is, with the operating parameters corresponding to the medium amount of food; when it is determined that the amount of food contained in the cooking cavity is the fourth amount of food, the cooking appliance is controlled to operate with the operating parameters corresponding to the fourth amount of food, that is, with the operating parameters corresponding to the large amount of food, so as to ensure the cooking effect of the cooking appliance.
