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

To this end, a first aspect of the present invention proposes a control method of a cooking appliance.

A second aspect of the present invention proposes a control device of a cooking appliance.

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

A fourth aspect of the invention proposes a readable storage medium.

In view of the above, a first aspect of the present invention provides a control method of a cooking appliance, wherein the cooking appliance includes a cooking cavity, and the control method includes obtaining a preset temperature of a bottom of the cooking cavity in a preset time period based on a start of the cooking appliance, and determining an amount of food in the cooking cavity according to the preset temperature.

After the cooking utensil starts to operate, the control method of the cooking utensil firstly obtains at least two preset time periods in the operation process of the cooking utensil, then obtains one preset temperature of the bottom of the cooking cavity in each preset time period, and finally determines the food amount in the cooking cavity according to the corresponding preset temperature obtained in each preset time period, thereby realizing the determination of the food amount in the cooking cavity.

Specifically, the food in the cooking cavity can be rice, millet or other rice food, and the cooking utensil can be used for determining the rice amount in the cooking cavity according to the preset temperature by acquiring at least one preset temperature in a preset time period in the cooking process, so that the operation parameters of the cooking utensil can be controlled according to the rice amount, the phenomenon of clamping, bottom pasting or over-thin of cooked rice is avoided, and the cooking effect is ensured.

Specifically, the cooking appliance may be provided with a temperature detecting member disposed at the bottom of the cooking cavity between the temperature detecting member and the temperature detecting member for detecting the temperature of the bottom of the cooking cavity.

According to the control method of the cooking utensil, in the operation process of the cooking utensil, the temperature of the bottom of the cooking cavity is detected, so that the temperature of food materials in direct contact with the bottom of the cooking cavity is detected, the phenomenon that the food materials are burnt off due to the fact that the temperature is too high or the temperature is too low is avoided, and effective cooking is impossible.

In addition, according to the control method of the cooking utensil in the technical scheme provided by the invention, the control method can also have the following additional technical characteristics:

In the technical scheme, the method comprises the steps of obtaining the temperature of the bottom of the cooking cavity in a preset time period, stopping heating the cooking cavity for a first time period based on the fact that the temperature of the bottom of the cooking cavity reaches a first temperature threshold, obtaining the first highest temperature of the bottom of the cooking cavity in the first time period, heating the cooking cavity for a second time period based on the fact that the heating time period is stopped, and obtaining the first lowest temperature of the bottom of the cooking cavity in the second time period.

In the technical scheme, the preset temperature of the bottom of the cooking cavity in two preset time periods in the operation process of the cooking appliance can be obtained, and then the food amount in the cooking cavity can be judged through the corresponding preset temperatures of the two preset time periods.

Specifically, after the cooking appliance starts to operate, the cooking appliance can start to heat the cooking cavity through the heating device, and the temperature of the bottom of the cooking cavity is obtained in real time through the temperature detecting piece; when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to stop running, namely heating the cooking cavity is stopped, and the first time is continued, namely a preset time period in the running process of the cooking appliance. And continuously acquiring the temperature of the bottom of the cooking cavity through the temperature detection piece in the first time period, and recording the highest temperature of the bottom of the cooking cavity in the first time period, wherein the highest temperature is a preset temperature value in a preset time period of the first time period, namely the first highest temperature. It should be noted that, after the heating device stops operating, since the heating device still has a high residual temperature, the temperature of the bottom of the cooking cavity does not immediately decrease, but continues to increase, and therefore, the temperature of the bottom of the cooking cavity is not the highest temperature of the bottom of the cooking cavity during the first period of time at the moment the heating device stops heating.

Further, when the heating device stops heating the cooking cavity for a first time, the heating device is started, the cooking cavity is heated through the heating device, and a second time is continued, wherein the second time is another preset time period in the operation process of the cooking appliance. And continuously detecting the temperature of the bottom of the cooking cavity through the temperature detection piece in the second time period, and recording the lowest temperature of the bottom of the cooking cavity in the second time period, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second time period, namely the first lowest temperature. It should be noted that, during a short period of time when the heating device starts to operate, since 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 continues to decrease, and therefore, the temperature of the bottom of the cooking cavity is not the lowest temperature of the bottom of the cooking cavity during the second period of time when the heating device starts to heat.

Further, the food material amount in the cooking cavity is determined through the first highest temperature and the first lowest temperature, accuracy of determining the food material amount in the cooking cavity is guaranteed, and then parameter control of the cooking appliance can be carried out according to the food material amount in the cooking cavity, cooking effect of the cooking appliance is improved, and user experience is improved.

In any one of the above technical solutions, the step of determining the amount of food materials in the cooking cavity according to the preset temperature further includes judging whether a difference between the first highest temperature and the first lowest temperature is smaller than a first preset value, determining the amount of the food materials as a first amount of the food materials if the difference is smaller than the first preset value, determining the amount of the food materials as a second amount of the food materials if the difference is smaller than the first preset value, and determining the amount of the food materials as a second amount of the food materials if the difference is smaller than the first preset value.

In this technical scheme, after the first highest temperature in the first duration and the first lowest temperature in the second duration are determined, the determination of the food amount in the cooking cavity may be performed according to the first highest temperature and the first lowest temperature. Specifically, the first highest temperature is subtracted from the first lowest temperature to obtain a difference between the first highest temperature and the first lowest temperature, the difference is compared with a first preset value, if the difference is smaller than the first preset value, the food amount in the current cooking cavity can be determined to be the first food amount, and if the difference is larger than the first preset value, the food amount in the current cooking cavity can be determined to be the second food amount.

Specifically, the first amount of food material is smaller than the second amount of food material, i.e., the first amount of food material is a smaller amount of food material and the second amount of food material is a larger amount of food material. It can be understood that if the amount of food in the cooking cavity is small, the temperature change speed of the bottom of the cooking cavity of the cooking appliance is high in the heating process, and the heating device is heated by the heating device when the temperature of the bottom of the cooking cavity is not reduced to a lower temperature in the heating process from stopping heating to starting heating. Thus, the difference between the first highest temperature and the first lowest temperature is not too large. Correspondingly, if the food amount in the cooking cavity is large, the temperature change speed of the bottom of the cooking cavity of the cooking appliance in the heating process is low, and the temperature of the bottom of the cooking cavity of the heating device is greatly reduced from the heating stop to the heating start. Therefore, the difference between the first highest temperature and the first lowest temperature is large. That is, the first amount of food material is less than the second amount of food material.

Further, when the food material amount in the cooking cavity is determined to be the first food material amount, the cooking appliance can be controlled to operate according to the operation parameters corresponding to the first food material amount, namely, the operation parameters corresponding to the smaller food material amount, and when the food material amount in the cooking cavity is determined to be the second food material amount, the cooking appliance is controlled to operate according to the operation parameters corresponding to the second food material amount, namely, the operation parameters corresponding to the larger food material amount, so that the cooking effect of the cooking appliance is ensured.

In any one of the above technical solutions, further heating the cooking cavity for a second period of time includes controlling the cooking appliance to heat the cooking cavity with 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.

In the technical scheme, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, heating the cooking cavity is stopped, and the first time is continued, when the time for stopping heating the cooking cavity by the heating device reaches the first time, the heating device is started, the heating device is used for heating the cooking cavity, and the temperature of the bottom of the cooking cavity is detected in real time by the temperature detection piece, until the temperature of the bottom of the cooking cavity reaches a second temperature threshold, the time for starting heating the cooking cavity until the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time, in the second time, the temperature of the bottom of the cooking cavity is continuously detected by the temperature detection piece, and the lowest temperature of the bottom of the cooking cavity in the second time is recorded, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second time, namely the first lowest temperature. Further, the food material amount in the cooking cavity is determined through the first highest temperature and the first lowest temperature, accuracy of determining the food material amount in the cooking cavity is guaranteed, and then parameter control of the cooking appliance can be carried out according to the food material amount in the cooking cavity, cooking effect of the cooking appliance is improved, and user experience is improved.

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

In any of the above technical solutions, the step of obtaining the preset temperature of the bottom of the cooking cavity in the preset time period further includes stopping heating the cooking cavity for a third time period based on the temperature of the bottom of the cooking cavity reaching a second temperature threshold, obtaining a second highest temperature of the bottom of the cooking cavity in the third time period, heating the cooking cavity for a fourth time period based on the heating stopping time period reaching the third time period, and obtaining a second lowest temperature of the bottom of the cooking cavity in the fourth time period.

In the technical scheme, the preset temperature of the bottom of the cooking cavity in four preset time periods in the operation process of the cooking appliance can be obtained, and then the food amount in the cooking cavity can be judged through the corresponding preset temperatures in the four preset time periods.

Specifically, after the cooking utensil starts to operate, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold value, the heating device is controlled to stop operating, namely heating the cooking cavity, and the heating device continues to perform a first period of time, and in the first period of time, the temperature of the bottom of the cooking cavity is continuously obtained through the temperature detection piece, and the highest temperature of the bottom of the cooking cavity in the first period of time is recorded, wherein the highest temperature is a preset temperature value in a preset time period of the first period of time, namely the first highest temperature. When the heating device stops heating the cooking cavity for a first time, the heating device is started, the heating device is used for heating the cooking cavity for a second time, the temperature of the bottom of the cooking cavity is continuously detected through the temperature detecting piece in the second time, and the lowest temperature of the bottom of the cooking cavity in the second time is recorded.

Further, in the second time period, when the temperature of the bottom of the cooking cavity reaches the second temperature threshold, the heating device is controlled to stop heating the cooking cavity, and the third time period is continued, wherein the first time period is a preset time period in the operation process of the cooking appliance. And continuously acquiring the temperature of the bottom of the cooking cavity through the temperature detection piece in the third time period, and recording the highest temperature of the bottom of the cooking cavity in the third time period, wherein the highest temperature is a preset temperature value in a preset time period of the third time period, namely the second highest temperature. It should be noted that, after the heating device stops operating, since the heating device still has a high residual temperature, the temperature of the bottom of the cooking cavity does not immediately decrease, but continues to increase, and therefore, the temperature of the bottom of the cooking cavity is not the highest temperature of the bottom of the cooking cavity during the third period of time at the moment the heating device stops heating.

Further, when the heating device stops heating the cooking cavity for a third time period, the heating device is started, the cooking cavity is heated through the heating device, and a fourth time period is continued, wherein the fourth time period is another preset time period in the operation process of the cooking appliance. And in the fourth time period, continuously detecting the temperature of the bottom of the cooking cavity through the temperature detection piece, and recording the lowest temperature of the bottom of the cooking cavity in the fourth time period, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the fourth time period, namely the second lowest temperature. It should be noted that, during a short period of time when the heating device starts to operate, since 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 continues to decrease, and therefore, the temperature of the bottom of the cooking cavity is not the lowest temperature of the bottom of the cooking cavity during the fourth period of time when the heating device starts to heat.

Further, the food material quantity in the cooking cavity is determined through the first highest temperature, the first lowest temperature, the second highest temperature and the second lowest temperature, so that the accuracy of judging the food material quantity in the cooking cavity is further improved, the cooking effect of the food material is ensured, and the user experience is improved.

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

In the technical scheme, when the food material quantity in the cooking cavity is determined to be the second food material quantity by the first highest temperature and the first lowest temperature, the food material quantity in the cooking cavity can be further judged by the second highest temperature and the second lowest temperature, so that the accuracy of judging the food material quantity in the cooking cavity is improved.

Specifically, when the difference between the first highest temperature and the first lowest temperature is greater than a first preset value, the current food material amount in the cooking cavity can be determined to be the second food material amount, further, the second lowest temperature is subtracted from the second highest temperature to obtain the difference between the second highest temperature and the second lowest temperature, and then further determining the food material amount in the cooking cavity is achieved according to the difference between the second highest temperature and the second lowest temperature.

In any of the above technical solutions, the step of determining the food amount according to the difference between the second highest temperature and the second lowest temperature further includes determining whether the difference between the second highest temperature and the second lowest temperature is smaller than a second preset value, determining that the food amount is a third food amount if the difference is smaller than the second preset value, determining that the food amount is a fourth food amount if the difference is smaller than the second preset value, and determining that the food amount is a fourth food amount if the difference is smaller than the second preset value.

Specifically, when the difference between the first highest temperature and the first lowest temperature is greater than a first preset value, the food material amount in the current cooking cavity can be determined to be the second food material amount, further, the second lowest temperature is subtracted from the second highest temperature to obtain a difference between the second highest temperature and the second lowest temperature, the difference is compared with the second preset value, if the difference is smaller than the second preset value, the food material amount in the current cooking cavity can be determined to be the third food material amount, and if the difference is greater than the second preset value, the food material amount in the current cooking cavity can be determined to be the fourth food material amount.

Specifically, the third amount of food material is smaller than the fourth amount of food material, i.e., the third amount of food material is a medium amount of food material, and the fourth amount of food material is a large amount of food material, relative to the first amount of food material. It can be understood that if the amount of food in the cooking cavity is small, the temperature change speed of the bottom of the cooking cavity of the cooking appliance is high in the heating process, and the heating device is heated by the heating device when the temperature of the bottom of the cooking cavity is not reduced to a lower temperature in the heating process from stopping heating to starting heating. Therefore, the difference between the second highest temperature and the second lowest temperature is not too large. Correspondingly, if the food amount in the cooking cavity is large, the temperature change speed of the bottom of the cooking cavity of the cooking appliance in the heating process is low, and the temperature of the bottom of the cooking cavity of the heating device is greatly reduced from the heating stop to the heating start. Therefore, the difference between the second highest temperature and the second lowest temperature is large. Therefore, the third amount of food material is smaller than the fourth amount of food material.

Further, when the food material amount in the cooking cavity is determined to be the third food material amount, the cooking appliance can be controlled to operate according to the operation parameter corresponding to the third food material amount, namely, the operation parameter corresponding to the medium food material amount, and when the food material amount in the cooking cavity is determined to be the fourth food material amount, the cooking appliance is controlled to operate according to the operation parameter corresponding to the fourth food material amount, namely, the operation parameter corresponding to the large food material amount, so that the cooking effect of the cooking appliance is ensured.

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

In the technical scheme, when the temperature of the bottom of the cooking cavity reaches a second temperature threshold, heating the cooking cavity is stopped and lasts for a third time period, when the time period that the heating device stops heating the cooking cavity reaches the third time period, the heating device is started, the cooking cavity is heated through the heating device, the cooking appliance is kept to be heated with second preset power and lasts for a fourth time period, and meanwhile the temperature of the bottom of the cooking appliance is detected in real time in the fourth time period, so that the second lowest temperature in the fourth time period is obtained.

In particular, the second preset power may be any value between one sixteenth and one nominal power of the cooking appliance. And, the second preset power can be smaller than the first preset power so as to avoid the food material in the cooking cavity from being burnt out caused by the too high heating speed.

In any of the above embodiments, further comprising, before the step of obtaining the preset temperature of the bottom of the cooking cavity in the preset time period, controlling the cooking appliance to heat the cooking cavity with a third preset power.

According to the technical scheme, when cooking starts, the cooking utensil can be controlled to operate at a third preset power to heat the cooking cavity, meanwhile, the temperature of the bottom of the cooking cavity is obtained in real time through the temperature detection piece, and when the temperature of the bottom of the cooking cavity reaches a first temperature threshold value, the heating device is controlled to stop operating, namely, the heating of the cooking cavity is stopped.

Specifically, the third preset power may be any value between one half of the rated power of the cooking appliance and the rated power. And the third preset power can be larger than or equal to the first preset power so as to ensure the heating efficiency of the cooking utensil and ensure that the temperature at the bottom of the cooking cavity is quickly and effectively increased to a first temperature threshold value, so that the food amount in the cooking cavity is conveniently determined.

In any one of the above technical solutions, the control method of the cooking appliance further includes controlling operation parameters of the cooking appliance according to the food amount.

In the technical scheme, through obtaining the corresponding preset temperature in four preset time periods in the operation process of the cooking utensil, the accurate judgment of the food amount in the cooking cavity is realized, and further, the cooking utensil is controlled to operate with corresponding operation parameters according to the food amount in the cooking cavity, so that the cooking effect of the food can be ensured, the phenomenon that the food is burnt or is not completely mature is avoided, the cooking process is not required to be detected by a user, the operation of the user is facilitated, and the user experience is improved.

Specifically, when the food amount in the cooking cavity is determined to be the first food amount, the cooking appliance can be controlled to operate according to the operation parameters corresponding to the first food amount, namely, the operation parameters corresponding to the smaller food amount, when the food amount in the cooking cavity is determined to be the second food amount through the first highest temperature and the first lowest temperature, the food amount in the cooking cavity can be further judged through the second highest temperature and the second lowest temperature, when the food amount in the cooking cavity is determined to be the third food amount, the cooking appliance can be controlled to operate according to the operation parameters corresponding to the third food amount, namely, the operation parameters corresponding to the medium food amount, and when the food amount in the cooking cavity is determined to be the fourth food amount, the cooking appliance is controlled to operate according to the operation parameters corresponding to the fourth food amount, namely, the operation parameters corresponding to the large food amount, so that the cooking effect of the cooking appliance is ensured.

And continuously acquiring the temperature of the bottom of the cooking cavity through the temperature detection piece in the first time period, and recording the highest temperature of the bottom of the cooking cavity in the continuous process of the first time period, wherein the highest temperature is a preset temperature value in a preset time period of the first time period, namely a first highest temperature B. It should be noted that, after the heating device stops operating, since the heating device still has a high residual temperature, the temperature of the bottom of the cooking cavity does not immediately decrease, but continues to increase, so the temperature of the bottom of the cooking cavity is not the highest temperature of the bottom of the cooking cavity during the first time duration.

Specifically, the first temperature threshold may be set between 60 degrees celsius and 110 degrees celsius, and the first duration is between 10 seconds and 5 minutes.

Further, when the heating device stops heating the cooking cavity for a first time, the heating device is started, the cooking cavity is heated through the heating device, and a second time is continued, wherein the second time is another preset time period in the operation process of the cooking appliance. And continuously detecting the temperature of the bottom of the cooking cavity through the temperature detection piece in the second duration, and recording the lowest temperature of the bottom of the cooking cavity in the duration process of the second duration, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second duration, namely the first lowest temperature C. It should be noted that, during a short period of time when the heating device starts to operate, since 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 continues to decrease, and therefore, the temperature of the bottom of the cooking cavity is not the lowest temperature during the second period of time when the heating device starts to heat.

The food amount in the cooking cavity is determined through the first highest temperature and the first lowest temperature, the accuracy of determining the food amount in the cooking cavity is guaranteed, and then the parameter control of the cooking appliance can be carried out according to the food amount in the cooking cavity, the cooking effect of the cooking appliance is improved, and the user experience is improved.

Further, after the first maximum temperature in the first duration and the first minimum temperature in the second duration are determined, the determination of the food amount in the cooking cavity may be performed according to the first maximum temperature and the first minimum temperature. Specifically, the first minimum temperature is subtracted from the first maximum temperature to obtain a difference between the first minimum temperature and the first maximum temperature, the difference is compared with a first preset value, if the difference is smaller than the first preset value, the food amount in the current cooking cavity can be determined to be the first food amount, and if the difference is larger than the first preset value, the food amount in the current cooking cavity can be determined to be the second food amount.

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.

Specifically, the second amount of food material is greater than the first amount of food material, i.e., the first amount of food material is a smaller amount of food material and the second amount of food material is a larger amount of food material. It can be understood that if the amount of food in the cooking cavity is small, the temperature change speed of the bottom of the cooking cavity of the cooking appliance is high in the heating process, and the heating device is heated by the heating device when the temperature of the bottom of the cooking cavity is not reduced to a lower temperature in the heating process from stopping heating to starting heating. Thus, the difference between the first highest temperature and the first lowest temperature is not too large. Correspondingly, if the food amount in the cooking cavity is large, the temperature change speed of the bottom of the cooking cavity of the cooking appliance in the heating process is low, and the temperature of the bottom of the cooking cavity of the heating device is greatly reduced from the heating stop to the heating start. Therefore, the difference between the first minimum temperature and the first maximum temperature is large. That is, the second amount of food material is greater than the first amount of food material.

Further, when the food material amount contained in the cooking cavity is determined to be the first food material amount, the cooking appliance can be controlled to operate according to the operation parameters corresponding to the first food material amount, namely the operation parameters corresponding to the smaller food material amount, and when the food material amount contained in the cooking cavity is determined to be the second food material amount, the cooking appliance is controlled to operate according to the operation parameters corresponding to the second food material amount, namely the operation parameters corresponding to the larger food material amount, so that the cooking effect of the cooking appliance is ensured.

Further, heating the cooking cavity for a second period of time includes controlling the cooking appliance to heat the cooking cavity with 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.

Specifically, when the temperature of the bottom of the cooking cavity reaches a first temperature threshold, heating the cooking cavity is stopped and lasts for a first time period, when the heating device stops heating the cooking cavity for the first time period, the heating device is started, the heating device is used for heating the bottom of the cooking cavity and detecting the temperature of the bottom of the cooking cavity in real time through the temperature detection piece, until the temperature of the bottom of the cooking cavity reaches a second temperature threshold, the time period from the heating device to the time point when the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time period, in the second time period lasting process, the temperature of the bottom of the cooking cavity is continuously detected through the temperature detection piece, and the lowest temperature of the bottom of the cooking cavity in the second time period lasting process is recorded, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second time period, namely the first lowest temperature. Further, the food material amount contained in the cooking cavity is determined through the first minimum temperature and the first maximum temperature, accuracy of determining the food material amount contained in the cooking cavity is guaranteed, and then parameter control of the cooking appliance can be carried out according to the food material amount contained in the cooking cavity, cooking effect of the cooking appliance is improved, and user experience is improved.

According to an embodiment of the present invention, as shown in fig. 3, there is provided a control method of a cooking appliance, the method including:

step S302, acquiring the temperature of the bottom of the cooking cavity based on the starting operation of the cooking appliance;

step S304, stopping heating the cooking cavity based on the temperature of the bottom of the cooking cavity reaching a first temperature threshold, and continuing for a first duration;

Step S326, determining the food material amount as a third food material amount;

step S328, determining the food material amount as the fourth food material amount.

In this embodiment, the preset temperature of the bottom of the cooking cavity in four preset time periods during the operation of the cooking appliance may be obtained, and then the food amount contained in the cooking cavity may be determined by the preset temperatures corresponding to the four preset time periods.

Specifically, as shown in fig. 6 and fig. 7, after the cooking appliance starts to operate, when the temperature of the bottom of the cooking cavity reaches the first temperature threshold a, the heating device is controlled to stop operating, that is, to stop heating the cooking cavity, for a first duration, in the first duration, the temperature of the bottom of the cooking cavity is continuously obtained through the temperature detecting member, and the highest temperature of the bottom of the cooking cavity in the first duration is recorded, where the highest temperature is a preset temperature value in a preset time period corresponding to the first duration, that is, the first highest temperature B. When the heating device stops heating the cooking cavity for a first time, the heating device is started, the heating device is used for heating the cooking cavity for a second time, the temperature of the bottom of the cooking cavity is continuously detected through the temperature detecting piece in the second time duration process, and the first lowest temperature C of the bottom of the cooking cavity in the second time duration process is recorded.

Further, in the duration of the second period, when the temperature of the bottom of the cooking cavity reaches the second temperature threshold D, the heating device is controlled to stop heating the cooking cavity, and the duration of the third period is kept, wherein the first period is a preset period of time in the operation process of the cooking appliance. And in the duration of the third duration, continuously acquiring the temperature of the bottom of the cooking cavity through the temperature detection piece, and recording the highest temperature of the bottom of the cooking cavity in the duration of the third duration, wherein the highest temperature is a preset temperature value in a preset time period of the third duration, namely a second highest temperature E. It should be noted that, after the heating device stops operating, since the heating device still has a high residual temperature, the temperature of the bottom of the cooking cavity does not immediately decrease but continues to increase, and therefore, the temperature of the bottom of the cooking cavity is not the highest temperature of the bottom of the cooking cavity during the third duration at the moment when the heating device stops heating.

Specifically, the second temperature threshold may be set at 80 degrees celsius to 120 degrees celsius and the third duration is 10 seconds to 5 minutes.

Further, when the heating device stops heating the cooking cavity for a third time period, the heating device is started, the cooking cavity is heated through the heating device, and a fourth time period is continued, wherein the fourth time period is another preset time period in the operation process of the cooking appliance. In the fourth time duration, the temperature of the bottom of the cooking cavity is continuously detected through the temperature detecting piece, and the lowest temperature of the bottom of the cooking cavity in the fourth time duration is recorded, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the fourth time duration, namely the second lowest temperature F. It should be noted that, during a short period of time when the heating device starts to operate, since 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 continues to decrease, and therefore, the temperature of the bottom of the cooking cavity is not the lowest temperature during the fourth duration.

Specifically, the second maximum temperature is 80 to 120 degrees celsius, the second minimum temperature is 60 to 120 degrees celsius, and the fourth time period is 10 seconds to 5 minutes.

Further, the food material amount contained in the cooking cavity is determined through the first highest temperature, the first lowest temperature, the second highest temperature and the second lowest temperature, so that the accuracy of judging the food material amount contained in the cooking cavity is further improved, the cooking effect of the food material is ensured, and the user experience is improved.

Further, when the food material amount contained in the cooking cavity is determined to be the second food material amount by the first minimum temperature and the first maximum temperature, the food material amount contained in the cooking cavity can be further judged by the second minimum temperature and the second maximum temperature, so that the accuracy of judging the food material amount contained in the cooking cavity is improved.

Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than a first preset value, the current food material amount contained in the cooking cavity can be determined to be a second food material amount, further, the second minimum temperature is subtracted from the second maximum temperature to obtain a difference between the second minimum temperature and the second maximum temperature, and then, further, the food material amount contained in the cooking cavity is determined according to the difference between the second minimum temperature and the second maximum temperature.

Specifically, when the difference between the first minimum temperature and the first maximum temperature is greater than a first preset value, the food material amount contained in the current cooking cavity can be determined to be a second food material amount, further, the second minimum temperature is subtracted from the second maximum temperature to obtain a difference between the second minimum temperature and the second maximum temperature, the difference is compared with a second preset value, if the difference is smaller than the second preset value, the food material amount contained in the current cooking cavity can be determined to be a third food material amount, and if the difference is greater than the second preset value, the food material amount contained in the current cooking cavity can be determined to be a fourth food material amount.

Specifically, the third amount of food material is smaller than the fourth amount of food material, i.e., the third amount of food material is a medium amount of food material, and the fourth amount of food material is a large amount of food material, relative to the first amount of food material. It can be understood that if the amount of food contained in the cooking cavity is small, the temperature change speed of the bottom of the cooking cavity in the heating process of the cooking appliance is high, and when the temperature of the bottom of the cooking cavity is not reduced to a lower temperature in the heating process from stopping heating to starting heating of the heating device, the temperature will rise under the heating of the heating device. Therefore, the difference between the second highest temperature and the second lowest temperature is not too large. Correspondingly, if the food material amount contained in the cooking cavity is large, the temperature change speed of the bottom of the cooking cavity of the cooking appliance in the heating process is low, and the temperature of the bottom of the cooking cavity of the heating device is greatly reduced from the heating stop to the heating start. Therefore, the difference between the second lowest temperature and the second highest temperature is large. Therefore, the third amount of food material is smaller than the fourth amount of food material.

Further, when the food material amount contained in the cooking cavity is determined to be the third food material amount, the cooking appliance can be controlled to operate according to the operation parameters corresponding to the third food material amount, namely, the operation parameters corresponding to the medium food material amount, and when the food material amount contained in the cooking cavity is determined to be the fourth food material amount, the cooking appliance is controlled to operate according to the operation parameters corresponding to the fourth food material amount, namely, the operation parameters corresponding to the large food material amount, so that the cooking effect of the cooking appliance is ensured.

Further, heating the cooking cavity for a fourth period of time includes controlling the cooking appliance to heat the cooking cavity at a second preset power for the fourth period of time.

Specifically, when the temperature of the bottom of the cooking cavity reaches a second temperature threshold, heating the cooking cavity is stopped for a third time period, when the time period that the heating device stops heating the cooking cavity reaches the third time period, the heating device is started, the cooking cavity is heated through the heating device, the cooking appliance is kept to be heated with second preset power for a fourth time period, and meanwhile the temperature of the bottom of the cooking appliance is detected in real time in the continuous process of the fourth time period, so that the second lowest temperature in the continuous process of the fourth time period is obtained.

In particular, the second preset power may be any value between one sixteenth and one nominal power of the cooking appliance. And, the second preset power can be smaller than the first preset power, so that the food materials contained in the cooking cavity are prevented from being burnt out due to the fact that the heating speed is too high.

In the embodiment, when the cooking starts, the cooking utensil can be controlled to operate at a third preset power to heat the cooking cavity, meanwhile, the temperature of the bottom of the cooking cavity is obtained in real time through the temperature detection piece, and when the temperature of the bottom of the cooking cavity reaches a first temperature threshold value, the heating device is controlled to stop operating, namely, the heating of the cooking cavity is stopped.

Specifically, the third preset power may be any value between one half of the rated power of the cooking appliance and the rated power. And the third preset power can be larger than or equal to the first preset power so as to ensure the heating efficiency of the cooking appliance, and ensure that the temperature of the bottom of the cooking cavity is quickly and effectively increased to a first temperature threshold value so as to determine the food amount contained in the cooking cavity.

Specifically, when the food amount contained in the cooking cavity is determined to be the first food amount, the cooking appliance can be controlled to operate according to the operation parameter corresponding to the first food amount, namely, the operation parameter corresponding to the smaller food amount, when the food amount contained in the cooking cavity is determined to be the second food amount through the first minimum temperature and the first maximum temperature, the food amount contained in the cooking cavity can be further judged through the second minimum temperature and the second maximum temperature, when the food amount contained in the cooking cavity is determined to be the third food amount, the cooking appliance can be controlled to operate according to the operation parameter corresponding to the third food amount, namely, the operation parameter corresponding to the medium food amount, and when the food amount contained in the cooking cavity is determined to be the fourth food amount, the cooking appliance is controlled to operate according to the operation parameter corresponding to the fourth food amount, namely, the operation parameter corresponding to the large food amount, so that the cooking effect of the cooking appliance is ensured.

According to a second aspect of the invention, a control device of a cooking appliance is provided, which comprises an acquisition unit and a determination unit, wherein the acquisition unit is used for acquiring a preset temperature of the bottom of a cooking cavity in a preset time period, and the determination unit is used for determining the food material quantity contained in the cooking cavity according to the preset temperature.

After the cooking utensil starts to operate, the control device of the cooking utensil firstly acquires preset time periods, which can be at least two, of the cooking utensil in the operation process through the acquisition unit, then respectively determines a preset temperature of the bottom of the cooking cavity in each preset time period, and finally, determines the food amount contained in the cooking cavity through the determination unit according to the corresponding preset temperature acquired in each preset time period, thereby realizing the determination of the food amount contained in the cooking cavity.

Specifically, the food that the cooking chamber held can be rice, millet or other rice class food, and cooking utensil can obtain the preset temperature in at least one preset time quantum through obtaining the unit in the cooking process, and then confirm that the unit can confirm the rice volume in the cooking chamber according to this preset temperature to can be according to the operation parameter of the rice volume's size control cooking utensil, the phenomenon that the meal that avoids cooking appears the clamp, the bottom is burnt out or is too thin, guarantees the effect of cooking.

According to the control method of the cooking utensil, in the operation process of the cooking utensil, the temperature of the bottom of the cooking cavity is detected, so that the temperature of food materials in direct contact with the bottom of the cooking cavity is detected, the phenomenon that the food materials are burnt off due to the fact that the temperature is too high or the temperature is too low and cannot be effectively cooked is avoided, further, the preset temperature of the bottom of the cooking cavity in a preset time period is obtained through the obtaining unit, and therefore the determining unit can determine the food materials contained in the cooking cavity according to the temperature of the bottom of the cooking cavity in the preset time period, the cooking utensil can adjust corresponding operation parameters according to the food materials contained in the cooking cavity, the cooking effect of the cooking utensil is improved, and user experience is improved.

Further, the preset temperatures of the bottoms of the cooking cavities in two preset time periods in the operation process of the cooking appliance are obtained, and then the food amount contained in the cooking cavities is judged through the corresponding preset temperatures of the two preset time periods.

The heating device is controlled to stop operating when the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity reaches a first temperature threshold value, namely, the heating of the cooking cavity is stopped, and the first time is continued, namely, a preset time period in the operation process of the cooking appliance. And continuously acquiring the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity through the temperature detection piece in the duration process of the first duration, and recording the highest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration process of the first duration, wherein the highest temperature is a preset temperature value in a preset time period of the first duration, namely the first highest temperature. It should be noted that, after the heating device stops operating, since the heating device still has a high residual temperature, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity does not immediately decrease, but continues to increase, and therefore, the temperature of the bottom of the cooking cavity at the moment when the heating device stops heating is not the highest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity during the duration of the first duration.

Further, when the heating device stops heating the cooking cavity for a first time, the heating device is started, the cooking cavity is heated through the heating device, and a second time is continued, wherein the second time is another preset time period in the operation process of the cooking appliance. And continuously detecting the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity through the temperature detection piece in the duration process of the second duration, and recording the lowest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration process of the second duration, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second duration, namely the first lowest temperature. It should be noted that, during a short period of time when the heating device starts to operate, since the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity does not rise immediately but continues to decrease, and therefore, the temperature of the bottom of the cooking cavity at the moment when the heating device starts to heat is not the lowest temperature of the bottom of the cooking cavity during the duration of the second period.

Further, the food material amount contained in the cooking cavity is determined through the first minimum temperature and the first maximum temperature, accuracy of determining the food material amount contained in the cooking cavity is guaranteed, and then parameter control of the cooking appliance can be carried out according to the food material amount contained in the cooking cavity, cooking effect of the cooking appliance is improved, and user experience is improved.

Further, after the first highest temperature in the duration of the first time period and the first lowest temperature in the duration of the second time period are determined, the judgment of the food material amount contained in the cooking cavity can be performed according to the first highest temperature and the first lowest temperature. Specifically, the first minimum temperature is subtracted from the first maximum temperature to obtain a difference value between the first minimum temperature and the first maximum temperature, the difference value is compared with a first preset value, if the difference value is smaller than the first preset value, the food material amount contained in the current cooking cavity can be determined to be the first food material amount, and if the difference value is larger than the first preset value, the food material amount contained in the current cooking cavity can be determined to be the second food material amount.

Specifically, the second amount of food material is greater than the first amount of food material, i.e., the first amount of food material is a smaller amount of food material and the second amount of food material is a larger amount of food material. It can be understood that if the amount of food contained in the cooking cavity is small, the temperature change speed of the bottom of the cooking cavity in the heating process of the cooking appliance is high, and when the temperature of the bottom of the cooking cavity is not reduced to a lower temperature in the heating process from stopping heating to starting heating of the heating device, the temperature will rise under the heating of the heating device. Thus, the difference between the first highest temperature and the first lowest temperature is not too large. Correspondingly, if the food material amount contained in the cooking cavity is large, the temperature change speed of the bottom of the cooking cavity of the cooking appliance in the heating process is low, and the temperature of the bottom of the cooking cavity of the heating device is greatly reduced from the heating stop to the heating start. Therefore, the difference between the first minimum temperature and the first maximum temperature is large. That is, the second amount of food material is greater than the first amount of food material.

Further, when the temperature of the bottom of the cooking cavity reaches the first temperature threshold, heating the cooking cavity is stopped and lasts for a first time period, when the heating device stops heating the cooking cavity for the first time period, the heating device is started, the heating device is used for heating the cooking cavity and detecting the temperature of the bottom of the cooking cavity in real time through the temperature detection piece, until the temperature of the bottom of the cooking cavity reaches the second temperature threshold, the time period from the heating device to the time when the temperature of the bottom of the cooking cavity reaches the second temperature threshold is the second time period, the temperature of the bottom of the cooking cavity is continuously detected through the temperature detection piece in the second time period in the continuous process, and the lowest temperature of the bottom of the cooking cavity in the continuous process of the second time period is recorded, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the second time period, namely the first lowest temperature. Further, the food material amount contained in the cooking cavity is determined through the first minimum temperature and the first maximum temperature, accuracy of determining the food material amount contained in the cooking cavity is guaranteed, and then parameter control of the cooking appliance can be carried out according to the food material amount contained in the cooking cavity, cooking effect of the cooking appliance is improved, and user experience is improved.

Further, the preset temperatures of the bottoms of the cooking cavities in four preset time periods in the operation process of the cooking appliance can be obtained, and then the food amount contained in the cooking cavities can be judged through the corresponding preset temperatures of the four preset time periods.

Specifically, after the cooking utensil starts to operate, when the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity reaches a first temperature threshold, the heating device is controlled to stop operating, namely heating the cooking cavity, and the heating device continues for a first duration, in the duration of the first duration, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity is continuously obtained through the temperature detection piece, and the highest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration of the first duration is recorded, wherein the highest temperature is a preset temperature value in a preset time period of the first duration, namely the first highest temperature. When the heating device stops heating the cooking cavity for a first time, the heating device is started, the heating device is used for heating the cooking cavity for a second time, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity is continuously detected through the temperature detecting piece in the duration process of the second time, and the lowest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration process of the second time is recorded.

Further, in the duration of the second duration, when the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity reaches the second temperature threshold, the heating device is controlled to stop heating the cooking cavity, and the duration of the third duration is prolonged, wherein the first duration is a preset time period in the operation process of the cooking appliance. And continuously acquiring the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity through the temperature detection piece in the duration process of the third duration, and recording the highest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration process of the third duration, wherein the highest temperature is a preset temperature value in a preset time period of the third duration, namely the second highest temperature. It should be noted that, after the heating device stops operating, since the heating device still has a higher residual temperature, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity does not immediately decrease, but continues to increase, and therefore, the temperature of the bottom of the cooking cavity at the moment when the heating device stops heating is not the highest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity during the duration of the third duration.

Further, when the heating device stops heating the cooking cavity for a third time period, the heating device is started, the cooking cavity is heated through the heating device, and a fourth time period is continued, wherein the fourth time period is another preset time period in the operation process of the cooking appliance. And continuously detecting the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity through the temperature detection piece in the duration process of the fourth duration, and recording the lowest temperature of the bottom of the cooking cavity at the bottom of the cooking cavity in the duration process of the fourth duration, wherein the lowest temperature is the corresponding preset temperature in the preset time period of the fourth duration, namely the second lowest temperature. It should be noted that, during a short period of time when the heating device starts to operate, since the temperature of the heating device is still lower than the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity, the temperature of the bottom of the cooking cavity at the bottom of the cooking cavity does not rise immediately but continues to decrease, and therefore, the temperature of the bottom of the cooking cavity at the moment when the heating device starts to heat is not the lowest temperature of the bottom of the cooking cavity during the duration of the fourth period.
