Description

Technical Field

[0001] The present invention relates to the field of household appliances, and more particularly, to a cooking appliance, a control method and a control system thereof, and a readable storage medium. Background Art

[0002] Under the same heating power, different amounts of food result in different heating-up situations. For example, when the amount of food is small, the heating-up speed is fast, and in this case, the phenomenon of "bottom burning" is likely to occur; when the amount of food is large, the heating-up speed is slow, and in this case, the heating-up speed is likely to be slow. Summary of the Invention

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

[0004] To this end, in a first aspect of the present invention, a control method for a cooking appliance is provided.

[0005] In a second aspect of the present invention, a control system for a cooking appliance is provided.

[0006] In a third aspect of the present invention, a cooking appliance is provided.

[0007] In a fourth aspect of the present invention, a readable storage medium is provided.

[0008] In a first aspect of the present invention, a control method for a cooking appliance is provided. The cooking appliance includes a stirring device. The control method for the cooking appliance includes: obtaining the amount of food in the cooking appliance; and adjusting the stirring speed of the stirring device according to the amount of food.

[0009] The control method for the cooking appliance proposed by the present invention can be used for a cooking appliance having a stirring device. Among them, when controlling the operation of the cooking appliance, the present invention first obtains the amount of food to be cooked in the container of the cooking appliance; then, according to the amount of food to be cooked in the container, the stirring speed of the stirring device is adjusted so that the stirring speed of the stirring device matches the amount of food. In this way, on the one hand, in the case of a small amount of food, the phenomenon of "bottom burning" caused by overheating of the food can be avoided; in the case of a large amount of food, the heating effect on the food can be ensured, and excessive heat loss due to over-stirring can be avoided, ensuring the heating effect on the food. Specifically, the amount of food includes, but is not limited to: the weight of the food, the volume of the food, etc.

[0010] Specifically, during the operation of the cooking appliance, under the same heating power, the food will have different heating-up situations due to different weights. For example, when the amount of food is small, the heating-up speed is fast, and in this case, the phenomenon of "bottom burning" is likely to occur; when the amount of food is large, the heating-up speed is slow, and in this case, the heating-up speed is likely to be slow.

[0011] Therefore, in the process of controlling the operation of the cooking appliance according to the present invention, the stirring speed of the stirring device can be adjusted according to the amount of food. When the amount of food is small, high-speed stirring is carried out to prevent "bottom burning", and when the amount of food is large, low-speed stirring is carried out to ensure heating up. In this way, on the one hand, the cooking speed of the food can be ensured, and on the other hand, the cooking effect of the food is ensured.

[0012] The control method of the cooking appliance according to the above technical solution of the present invention may further have the following additional technical features:

[0013] In the above technical solution, the stirring speed is negatively correlated with the amount of food.

[0014] In this technical solution, the stirring speed of the stirring device has a negative correlation with the amount of food. Specifically, when the cooking appliance operates at a certain heating power, the less the amount of food, the more obvious the heating effect of the food, and the easier it is to have the phenomenon of "bottom burning"; the more the amount of food, the slower the heating of the food, and the less likely it is to have the phenomenon of "bottom burning".

[0015] Therefore, when the amount of food is small, the stirring speed is controlled to increase to take away the excess heat through high-speed stirring to ensure the smooth progress of cooking; when the amount of food is large, the stirring speed is controlled to decrease to avoid excessive heat loss through low-speed stirring to ensure the heating efficiency.

[0016] In any of the above technical solutions, the step of adjusting the stirring speed of the stirring device according to the amount of food includes: obtaining the interval where the amount of food is located; adjusting the stirring speed according to the interval.

[0017] In this technical solution, after obtaining the amount of food, the interval where the amount of food is located is judged, and then the stirring speed corresponding to the interval is determined, and then the stirring device is controlled to operate at the stirring speed corresponding to the interval, which can prevent the occurrence of "bottom burning" while ensuring the heating efficiency of the food, and effectively ensure the cooking effect of the food.

[0018] Specifically, different intervals correspond to different stirring speeds. When the amount of food is in an interval, no matter which value in this temperature interval the amount of food is, the stirring device is controlled to operate at the stirring speed corresponding to the interval, thereby simplifying the control difficulty and facilitating the control of the cooking appliance.

[0019] In any of the above technical solutions, the step of obtaining the amount of food in the cooking appliance includes: obtaining the heating-up duration required for the food to raise the temperature by a unit; determining the amount of food according to the heating-up duration.

[0020] In this technical solution, when the cooking appliance operates, it can raise the temperature of the food to a certain level. With the heating power remaining unchanged, the more food there is, the longer the required time. Therefore, the present invention obtains the heating time required for the food to increase by a unit temperature, and then determines the amount of food based on the heating time to ensure the subsequent adjustment of the stirring speed of the stirring device.

[0021] In any of the above technical solutions, in the step of adjusting the stirring speed of the stirring device according to the amount of food, when the heating time is less than the first preset time, control the stirring device to operate at the first stirring speed.

[0022] In this technical solution, if the time required for the food to increase by a unit temperature is less than the first preset time, it indicates that the amount of food is small. At this time, control the stirring device to operate at a relatively high first stirring speed, so as to achieve heat dissipation by rapid stirring when heating a small amount of food and avoid the phenomenon of "bottom burning".

[0023] In this technical solution, the first preset time can be set according to the actual situation. Generally, it is necessary to ensure that the first preset time is between 30 seconds and two minutes. In this way, on the one hand, it ensures that the food has sufficient heating time, the temperature of the food rises significantly, and the temperature is easy to measure; on the other hand, it ensures the timeliness of detection and can timely adjust the stirring speed of the stirring device to ensure the cooking effect.

[0024] In this technical solution, the first stirring speed can be set according to the actual situation. Generally, it is necessary to ensure that the first stirring speed is relatively fast to ensure heat loss and avoid the phenomenon of "bottom burning".

[0025] In any of the above technical solutions, in the step of adjusting the stirring speed of the stirring device according to the amount of food, it further includes: when the heating time is greater than or equal to the first preset time and less than the second preset time, control the stirring device to operate at the second stirring speed; where the second stirring speed is less than the first stirring speed.

[0026] In this technical solution, if the time required for the food to increase by a unit temperature is greater than or equal to the first preset time and less than the second preset time, it means that the amount of food is appropriate. At this time, control the stirring device to operate at the medium-speed second stirring speed to achieve heat dissipation by stirring when heating the appropriate amount of food and avoid the phenomenon of "bottom burning".

[0027] In this technical solution, the second preset time can be set according to the actual situation. Generally, it should be greater than the first preset time. Specifically, the second preset time can be between 1 minute and 3 minutes. In this way, on the one hand, it ensures that the food has sufficient heating time, the temperature of the food rises significantly, and the temperature is easy to measure; on the other hand, it ensures the timeliness of detection and can timely adjust the stirring speed of the stirring device to ensure the cooking effect.

[0028] In this technical solution, the second stirring speed can be set according to the actual situation, and generally it should be less than the first stirring speed to avoid excessive heat loss.

[0029] In any of the above technical solutions, the step of adjusting the stirring speed of the stirring device according to the amount of food further includes: when the heating duration is greater than or equal to the second preset duration, controlling the stirring device to operate at a third stirring speed; wherein, the third stirring speed is less than the second stirring speed.

[0030] In this technical solution, if the time required for the food to increase by a unit temperature is greater than or equal to the second preset duration, it indicates that the amount of food is excessive. At this time, control the stirring device to operate at a low third stirring speed, or even control the stirring device not to stir the food, so as to avoid excessive heat loss and ensure the heating efficiency.

[0031] In this technical solution, the second stirring speed can be set according to the actual situation, and generally it should be less than the second stirring speed, or even stop stirring.

[0032] In any of the above technical solutions, the step of obtaining the amount of food in the cooking appliance includes: obtaining the temperature change amount of the food per unit time; determining the amount of food according to the temperature change amount.

[0033] In this technical solution, the operation of the cooking appliance can cause the food to increase a certain temperature. When the heating power remains unchanged, the more the amount of food, the smaller the temperature change per unit time. Therefore, the present invention obtains the temperature change amount of the food per unit time, and then judges the amount of food according to the temperature change amount to ensure the subsequent adjustment of the stirring speed of the stirring device.

[0034] In any of the above technical solutions, in the step of adjusting the stirring speed of the stirring device according to the amount of food, when the temperature change amount is less than the first change amount threshold, control the stirring device to operate at a fourth stirring speed.

[0035] In this technical solution, if the temperature change amount of the food per unit time is less than the first change amount threshold, it indicates that the amount of food is relatively large. At this time, control the stirring device to operate at a lower fourth stirring speed, or even control the stirring device not to stir the food, so as to avoid excessive heat loss and ensure the heating efficiency.

[0036] In this technical solution, the fourth stirring speed can be set according to the actual situation, and generally it should be ensured that the fourth stirring speed is small enough, or even stop stirring. The first change amount threshold can be set according to the actual situation, and generally it should be ensured that the first change amount threshold is small enough.

[0037] In any of the above technical solutions, the step of adjusting the stirring speed of the stirring device according to the amount of food further includes: when the temperature change amount is greater than or equal to the first change amount threshold and less than the second change amount threshold, controlling the stirring device to operate at a fifth stirring speed; wherein, the fifth stirring speed is greater than the fourth stirring speed.

[0038] In this technical solution, if the temperature change amount of the food per unit time is greater than or equal to the first change amount threshold and less than the second change amount threshold, it indicates that the amount of food is appropriate. At this time, control the stirring device to operate at a fifth stirring speed at medium speed, so as to achieve heat dissipation by stirring while heating the appropriate food and avoid the phenomenon of "bottom burning".

[0039] In this technical solution, the second change amount threshold can be set according to the actual situation, and generally should be greater than the first change amount threshold. In addition, the fifth stirring speed can be set according to the actual situation, and generally should be greater than the fourth stirring speed to avoid the phenomenon of "bottom burning".

[0040] In any of the above technical solutions, the step of adjusting the stirring speed of the stirring device according to the amount of food further includes: when the temperature change amount is greater than or equal to the second change amount threshold, controlling the stirring device to operate at a sixth stirring speed; wherein, the sixth stirring speed is greater than the fifth stirring speed.

[0041] In this technical solution, if the temperature change amount of the food per unit time is greater than or equal to and less than the second change amount threshold, it means that the amount of food is small. At this time, control the stirring device to operate at a higher sixth stirring speed, so as to achieve heat dissipation by rapid stirring while heating a small amount of food and avoid the phenomenon of "bottom burning".

[0042] In this technical solution, the sixth stirring speed can be set according to the actual situation, and generally should be greater than the fifth stirring speed.

[0043] In any of the above technical solutions, when the stirring device operates continuously, adjusting the stirring speed of the stirring device specifically means: adjusting the continuous stirring speed of the stirring device; or when the stirring device operates intermittently, adjusting the stirring speed of the stirring device specifically means: adjusting the average stirring speed of the stirring device; wherein, the stirring direction of the stirring device remains unchanged or changes alternately.

[0044] In this technical solution, when the cooking appliance is operating, it can stir the food continuously or intermittently. Therefore, when the stirring device stirs the food continuously, after obtaining the cooking temperature of the cooking appliance, the average stirring speed of the stirring device can be adjusted to ensure the stirring effect on the food and avoid the situation of "bottom burning" of the food. When the stirring device stirs the food intermittently, after obtaining the cooking temperature of the cooking appliance, the average stirring speed of the stirring device can be adjusted to ensure the stirring effect on the food and avoid the situation of "bottom burning" of the food.

[0045] In addition, the stirring direction of the stirring device remains unchanged or changes alternately, that is, the stirring direction of the stirring device can be in the same direction or in two directions of positive and negative alternation.

[0046] When the stirring direction of the stirring device remains unchanged, the requirements for the motor driving the stirring device can be reduced, so as to reduce the cost of the cooking appliance and at the same time reduce the control difficulty. When the stirring direction of the stirring device changes alternately, food entanglement on the stirring device can be prevented to ensure smooth stirring.

[0047] In any of the above technical solutions, the control method of the cooking appliance further includes: obtaining the running duration of the cooking appliance; when the running duration reaches the set duration, controlling the heating device and the stirring device to stop working.

[0048] In this technical solution, after adjusting the heating power of the heating device and the stirring speed of the stirring device, continue to control the cooking appliance to run, and obtain the running duration of the cooking appliance; when the running duration reaches the set duration, it means that the cooking is completed, and at this time, control the stirring device to stop working; when the running duration does not reach the set duration, it means that the cooking is not completed, and at this time, continue to control the stirring device to work until the cooking ends.

[0049] The second aspect of the present invention provides a control system for a cooking appliance, including: a memory, on which a program is stored; a processor, which can be used to execute the program to implement the control method of the cooking appliance in any of the above technical solutions.

[0050] In the control system of the cooking appliance proposed by the present invention, when the processor executes the program stored in the memory, it can implement the control method of the cooking appliance in any of the above technical solutions. Therefore, it has all the beneficial effects of the above control method of the cooking appliance, and will not be elaborated here one by one.

[0051] The third aspect of the present invention provides a cooking appliance, including: a container; a heating device for heating the container; a detection device for detecting the temperature inside the container; a stirring device for stirring the food inside the container; a control device, electrically connected to the stirring device and the detection device, and can be used to execute the control method of the cooking appliance in any of the above technical solutions.

Therefore, it has all the beneficial effects of the above control method of the cooking appliance, and will not be elaborated here one by one.

[0053] Specifically, the container can be used to hold the food to be cooked, the heating device can be used to supply heat to the container, the detection device can timely detect the temperature inside the container, the stirring device can be used to stir the food inside the container, the control device is electrically connected to the stirring device and the detection device.

[0063] In order to be able to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0064] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0065] Reference will now be made to Figures 1 to 5 describe a cooking appliance, a control method and a control system therefor, and a readable storage medium according to some embodiments of the present invention.

[0066] A first embodiment of the present invention provides a control method for a cooking appliance, which can be used for a cooking appliance having a stirring device. As Figure 1 shown, the control method of the cooking appliance includes:

[0067] Step 102, obtaining the amount of food in the cooking appliance;

[0068] Step 104, adjusting the stirring speed of the stirring device according to the amount of food.

[0069] When the present invention controls the operation of the cooking appliance, it first obtains the amount of food to be cooked in the container of the cooking appliance; then, according to the amount of food to be cooked in the container, it adjusts the stirring speed of the stirring device so that the stirring speed of the stirring device matches the amount of food.

[0070] In this way, on the one hand, when the amount of food is small, it is possible to avoid the phenomenon of "bottom burning" due to overheating of the food. When the amount of food is large, it is possible to ensure the heating effect on the food and avoid excessive heat loss due to over-stirring, thereby ensuring the heating effect on the food.

[0071] Specifically, during the operation of the cooking appliance, at the same heating power, the food will have different temperature rising situations due to different weights. For example, when the amount of food is small, the temperature rising speed is fast, and at this time, the phenomenon of "bottom burning" is likely to occur; when the amount of food is large, the temperature rising speed is slow, and at this time, the situation of slow temperature rising is likely to occur.

[0072] Specifically, the amount of food includes but is not limited to: the weight of the food, the volume of the food, etc. Changes in the above parameters will all cause changes in the temperature rising situation of the food and different temperature rising slopes. Therefore, the control method of the cooking appliance proposed by the present invention can adjust the stirring speed of the stirring device according to the weight of the food or according to the volume of the food, and the above embodiments can all be realized.

[0073] Therefore, during the process of controlling the cooking appliance to work, the stirring speed of the stirring device can be adjusted according to the amount of food, ensuring that the stirring speed of the food matches the heating process of the food. When the amount of food is small, high-speed stirring can be carried out to prevent "bottom burning", and when the amount of food is large, low-speed stirring can be carried out to ensure heating. In this way, on the one hand, the cooking speed of the food can be guaranteed, and on the other hand, the cooking effect of the food can be guaranteed.

[0074] The second embodiment of the present invention proposes a control method for a cooking appliance. On the basis of the first embodiment, further:

[0075] The stirring speed of the stirring device has a negative correlation with the amount of food. Specifically, when the cooking appliance operates at a certain heating power, the less the amount of food, the more obvious the heating effect of the food, and the easier it is for the food to appear the phenomenon of "bottom burning"; the more the amount of food, the slower the heating of the food, and the less likely it is to appear the phenomenon of "bottom burning", but at this time, stirring the food easily causes heat loss and affects the cooking efficiency.

[0076] Therefore, in this embodiment, when the amount of food is small, the stirring speed is controlled to increase to take away the excess heat through high-speed stirring to ensure the smooth progress of cooking; when the amount of food is large, the stirring speed is controlled to decrease to avoid excessive heat loss through low-speed stirring to ensure the heating efficiency. In addition, when the amount of food is large, the stirring of the food can even be stopped.

[0077] In addition, this embodiment has all the beneficial effects of the first embodiment. On the one hand, the cooking speed of the food can be guaranteed, and on the other hand, the cooking effect of the food can be guaranteed.

[0078] The third embodiment of the present invention proposes a control method for a cooking appliance. On the basis of the first embodiment, further:

[0079] After obtaining the food quantity measurement, judge the interval where the food quantity is located, and then determine the stirring speed corresponding to this interval, and then control the stirring device to operate at the stirring speed corresponding to this interval, while ensuring the heating efficiency of the food, preventing the occurrence of "bottom burning", and effectively ensuring the cooking effect of the food.

[0080] Specifically, different intervals correspond to different stirring speeds. When the amount of food is in an interval, no matter which value in this temperature interval the food amount is, the stirring device is controlled to operate at the stirring speed corresponding to this interval, thereby simplifying the control difficulty and facilitating the control of the cooking appliance.

[0081] In a specific embodiment, taking the first interval, the second interval, and the third interval as examples, the technical solution proposed by the present invention is further explained. Among them, any value in the first interval < any value in the second interval < any value in the third interval.

[0082] Specifically, when the amount of food is in the first interval, it indicates that the amount of food is small. The stirring device is controlled to stir the food at a relatively high speed, or directly at the maximum speed.

[0083] Specifically, when the amount of food is in the second interval, it indicates that the amount of food is appropriate. The stirring device is controlled to stir the food at a medium speed.

[0084] Specifically, when the amount of food is in the third interval, it indicates that the amount of food is large. The stirring device is controlled to stir the food at a relatively low speed, or even stop stirring.

[0085] In addition, this embodiment has all the beneficial effects of Embodiment 1. When the amount of food is small, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. When the amount of food is large, it can ensure the heating speed of the food.

[0086] The fourth embodiment of the present invention proposes a control method for a cooking appliance. On the basis of Embodiment 1, further:

[0087] The operation of the cooking appliance can raise the temperature of the food by a certain amount. When the heating power remains unchanged, the more the amount of food, the longer the time required to raise a fixed temperature difference. Therefore, the present invention obtains the heating time required for the food to increase by a unit temperature, and then judges the amount of food according to the heating time, so as to ensure the subsequent adjustment of the stirring speed of the stirring device.

[0088] In a specific embodiment, timing can be started when the food is at the first preset temperature and stopped when the food reaches the second preset temperature. The difference between the second preset temperature and the first preset temperature is used as the unit temperature, and the obtained time is used as the heating time.

[0089] In this embodiment, further, if the heating time required for the food to increase by a unit temperature is less than the first preset time, it indicates that the amount of food is small. At this time, the stirring device is controlled to operate at a relatively high first stirring speed, so as to dissipate heat by rapid stirring when heating a small amount of food and avoid the phenomenon of "bottom burning".

[0090] In a specific embodiment, the first preset time can be set according to the actual situation. Generally, it is necessary to ensure that the first preset time is between 30 seconds and 2 minutes. In this way, on the one hand, it ensures that the food has sufficient heating time, ensures that the temperature of the food rises significantly, and also ensures that the temperature is easy to measure; on the other hand, it ensures the timeliness of detection and ensures that the stirring speed of the stirring device can be adjusted in time to ensure the cooking effect. In addition, the first stirring speed can be set according to the actual situation. Generally, it is necessary to ensure that the first stirring speed is relatively fast to ensure heat loss and avoid the phenomenon of "bottom burning".

[0091] In a specific embodiment, the first preset duration can be 30 seconds, 1 minute, 1 minute and 30 seconds, 2 minutes, etc., and no specific limitation is made here.

[0092] In this embodiment, further, if the time required for the food to increase by a unit temperature is greater than or equal to the first preset duration and less than the second preset duration, it indicates that the amount of food is appropriate. At this time, the stirring device is controlled to operate at a second stirring speed of medium speed, so as to achieve heat dissipation by stirring while heating the food appropriately, and avoid the phenomenon of "bottom burning".

[0093] In a specific embodiment, the second preset duration can be set according to the actual situation, and generally should be greater than the first preset duration. Specifically, the second preset duration can be between 1 minute and 3 minutes. In this way, on the one hand, it ensures that the food has sufficient heating time, the temperature of the food increases significantly, and the temperature is easy to measure; on the other hand, it ensures the timeliness of detection, and ensures that the stirring speed of the stirring device can be adjusted in time to ensure the cooking effect. In addition, the second stirring speed can be set according to the actual situation, and generally should be less than the first stirring speed to avoid excessive heat loss.

[0094] In a specific embodiment, the second preset duration can be 1 minute, 1 minute and 30 seconds, 2 minutes, 2 minutes and 30 seconds, 3 minutes, etc., and no specific limitation is made here, but it is necessary to ensure that the second preset duration > the first preset duration.

[0095] In a specific embodiment, the second stirring speed can be set according to the actual situation, and generally should be less than the second stirring speed, or even stop stirring.

[0096] In this embodiment, further, if the time required for the food to increase by a unit temperature is greater than or equal to the second preset duration, it indicates that the amount of food is too much. At this time, the stirring device is controlled to operate at a third stirring speed of low speed, or even the stirring device is controlled not to stir the food to avoid excessive heat loss and ensure the heating efficiency.

[0097] In a specific embodiment, the third stirring speed can be set according to the actual situation, and generally should be less than the second stirring speed, or even stop stirring.

[0098] In a specific embodiment, specifically, different intervals correspond to different stirring speeds. When the amount of food is in an interval, no matter which value in this interval the amount of food is, the stirring device is controlled to operate at the stirring speed corresponding to this interval, thereby simplifying the control difficulty and facilitating the control of the cooking appliance.

[0099] In a specific embodiment, taking the first interval, the second interval, and the third interval as examples, the technical solution proposed by the present invention is further explained. Among them, any value within the first interval < any value within the second interval < any value within the third interval; the first stirring speed > the second stirring speed > the third stirring speed.

[0100] Specifically, when the heating duration is less than the first preset duration, it indicates that the food quantity is in the first interval; at this time, the stirring device is controlled to operate at the first stirring power.

[0101] Specifically, when the heating duration is greater than or equal to the first preset duration and less than the second working duration, it indicates that the food quantity is in the second interval; at this time, the stirring device is controlled to operate at the second stirring power.

[0102] Specifically, when the heating duration is greater than the second working duration, it indicates that the food quantity is in the third interval; at this time, the stirring device is controlled to operate at the third stirring power.

[0103] In addition, this embodiment has all the beneficial effects of Embodiment 1. In the case of a small amount of food, the phenomenon of "bottom burning" caused by overheating of the food can be avoided. In the case of a large amount of food, the heating speed of the food can be guaranteed.

[0104] The fifth embodiment of the present invention proposes a control method for a cooking appliance. On the basis of Embodiment 1, further:

[0105] The operation of the cooking appliance can raise the temperature of the food to a certain extent. When the heating power remains unchanged, the more the food quantity, the smaller the temperature change per unit time. Therefore, the present invention obtains the temperature change amount of the food per unit time, and then judges the food quantity according to the temperature change amount to ensure the subsequent adjustment of the stirring speed of the stirring device.

[0106] In this embodiment, further, if the temperature change amount of the food per unit time is less than the first change amount threshold, it indicates that the food quantity is large. At this time, the stirring device is controlled to operate at a lower fourth stirring speed, or even the stirring device is controlled not to stir the food to avoid excessive heat loss and ensure the heating efficiency.

[0107] In a specific embodiment, the fourth stirring speed can be set according to the actual situation. Generally, it is necessary to ensure that the fourth stirring speed is small enough, or even stop stirring. The first change amount threshold can be set according to the actual situation. Generally, it is necessary to ensure that the first change amount threshold is small enough.

[0108] In this embodiment, further, if the temperature change amount of the food within a unit time is greater than or equal to the first change amount threshold and less than the second change amount threshold, it indicates that the amount of food is appropriate. At this time, control the stirring device to operate at the fifth stirring speed in the medium speed, so as to achieve heat dissipation by stirring while heating the appropriate food and avoid the phenomenon of "bottom burning".

[0109] In a specific embodiment, the second change amount threshold can be set according to the actual situation, and generally should be greater than the first change amount threshold. In addition, the fifth stirring speed can be set according to the actual situation, and generally should be greater than the fourth stirring speed to avoid the phenomenon of "bottom burning".

[0110] In this embodiment, further, if the temperature change amount of the food within a unit time is greater than or equal to and less than the second change amount threshold, it indicates that the amount of food is small. At this time, control the stirring device to operate at the higher sixth stirring speed, so as to achieve heat dissipation by rapid stirring while heating a small amount of food and avoid the phenomenon of "bottom burning".

[0111] In a specific embodiment, the sixth stirring speed can be set according to the actual situation, and generally should be greater than the fifth stirring speed.

[0112] In a specific embodiment, specifically, different intervals correspond to different stirring speeds. When the amount of food is in an interval, no matter which value in this interval the amount of food is, control the stirring device to operate at the stirring speed corresponding to this interval, thereby simplifying the control difficulty and facilitating the control of the cooking appliance.

[0113] In a specific embodiment, taking the first interval, the second interval and the third interval as examples, the technical solution proposed by the present invention is further explained. Among them, any value in the first interval < any value in the second interval < any value in the third interval; the fourth stirring speed < the fifth stirring speed < the sixth stirring speed.

[0114] Specifically, when the temperature change amount of the cooking appliance within a unit time is less than the first change threshold, it indicates that the amount of food is in the first interval; at this time, control the stirring device to work at the fourth stirring power.

[0115] Specifically, when the temperature change amount of the cooking appliance within a unit time is greater than or equal to the first change threshold and less than the second change threshold, it indicates that the amount of food is in the second interval; at this time, control the stirring device to work at the fifth stirring power.

[0116] Specifically, when the temperature change amount of the cooking appliance within a unit time is greater than the second change threshold, it indicates that the amount of food is in the third interval; at this time, control the stirring device to work at the sixth stirring power.

[0117] In addition, this embodiment has all the beneficial effects of the first embodiment. When the amount of food is small, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. When the amount of food is large, it can ensure the heating speed of the food.

[0118] In a specific embodiment, the fourth stirring speed in this embodiment may be equal to the third stirring speed in the fourth embodiment, the fifth stirring speed in this embodiment may be equal to the second stirring speed in the fourth embodiment, and the sixth stirring speed in this embodiment may be equal to the first stirring speed in the fourth embodiment.

[0119] That is, as long as it is determined that the amount of food is in the first interval, the stirring device is controlled to stir the food at the first stirring power (the sixth stirring speed); as long as it is determined that the amount of food is in the second interval, the stirring device is controlled to stir the food at the second stirring power (the fifth stirring speed); as long as it is determined that the amount of food is in the third interval, the stirring device is controlled to stir the food at the third stirring power (the fourth stirring speed).

[0120] The sixth embodiment of the present invention proposes a control method for a cooking appliance. On the basis of the first embodiment, further:

[0121] In this embodiment, further, when the cooking appliance is running, it can continuously stir the food or intermittently stir the food. Therefore, when the stirring device continuously stirs the food, after obtaining the cooking temperature of the cooking appliance, the average stirring speed of the stirring device can be adjusted to ensure the stirring effect on the food and avoid the situation of "bottom burning" of the food. When the stirring device intermittently stirs the food, after obtaining the cooking temperature of the cooking appliance, the average stirring speed of the stirring device can be adjusted to ensure the stirring effect on the food and avoid the situation of "bottom burning" of the food.

[0122] In addition, the stirring direction of the stirring device remains unchanged or changes alternately. That is, the stirring direction of the stirring device can be in the same direction or in two directions of positive and negative alternation.

[0123] When the stirring direction of the stirring device remains unchanged, the requirements for the motor driving the stirring device can be reduced, so as to reduce the cost of the cooking appliance and at the same time reduce the control difficulty. When the stirring direction of the stirring device changes alternately, it can prevent the food from winding around the stirring device and ensure the smooth progress of stirring.

[0124] In addition, this embodiment has all the beneficial effects of the first embodiment. When the amount of food is small, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. When the amount of food is large, it can ensure the heating speed of the food.

[0125] The seventh embodiment of the present invention proposes a control method for a cooking appliance. On the basis of the first embodiment, further:

[0126] After adjusting the heating power of the heating device and the stirring speed of the stirring device, continue to control the cooking appliance to operate, and obtain the operation duration of the cooking appliance; when the operation duration reaches the set duration, it indicates that the cooking is completed, and at this time, control the stirring device to stop working; when the operation duration does not reach the set duration, it indicates that the cooking is not completed, and at this time, continue to control the stirring device to work until the cooking ends.

[0127] In addition, this embodiment has all the beneficial effects of Embodiment 1. When the amount of food is small, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. When the amount of food is large, it can ensure the heating speed of the food.

[0128] As Figure 2 shown, the eighth embodiment of the present invention proposes a control system 200 of a cooking appliance, including a memory 202 and a processor 204.

[0129] Wherein, when the processor 204 executes the program stored in the memory 202, it can implement the control method of the cooking appliance in any of the above embodiments. Therefore, it has all the beneficial effects of the above control method of the cooking appliance, and will not be elaborated one by one here.

[0130] Specifically, in the process of controlling the cooking appliance to work, the present invention can adjust the stirring speed of the stirring device according to the amount of food. When the amount of food is small, it stirs at a high speed to prevent "bottom burning", and when the amount of food is large, it stirs at a low speed to ensure temperature rise. In this way, on the one hand, it can ensure the cooking speed of the food, and on the other hand, it can ensure the cooking effect of the food.

[0131] As Figure 3 shown, the Nine embodiment of the present invention proposes a cooking appliance, including: a container 302, a heating device 304, a detection device 306, a stirring device 308 and a control device 310.

[0132] Wherein, the control device 310 can execute the control method of the cooking appliance in any of the above embodiments. Therefore, it has all the beneficial effects of the above control method of the cooking appliance. When the amount of food is small, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. When the amount of food is large, it can ensure the heating speed of the food, and will not be specifically elaborated here.

[0133] Specifically, the container 302 can be used to hold the food to be cooked, the heating device 304 can be used to supply heat to the container 302, the detection device 306 can timely detect the temperature inside the container 302, the stirring device 308 can be used to stir the food inside the container 302, and the control device 310 is electrically connected to the stirring device 308 and the detection device 306. The control device 310 can adjust the stirring speed of the stirring device 308 according to the amount of food to be cooked in the container 302, so that the stirring speed of the stirring device 308 matches the amount of food, while ensuring the heating efficiency of the food and preventing the situation of "bottom burning", effectively ensuring the cooking effect of the food.

[0134] The tenth embodiment of the present invention proposes a readable storage medium. The readable storage medium stores a program, and when the program is executed by a processor, it can implement the control method of the cooking appliance as described in any of the above embodiments. Therefore, it has all the beneficial effects of the above control method of the cooking appliance. In the case of a small amount of food, it can avoid the phenomenon of "bottom burning" caused by overheating of the food. In the case of a large amount of food, it can ensure the heating speed of the food, and will not be elaborated here specifically.

[0135] The first specific embodiment of the present invention proposes a cooking appliance. The cooking appliance is provided with a control device, which is mainly used for controlling the heating device, controlling the detection device, timing, emitting prompt signals, and performing data operations; of course, a separate timing device is also provided for timing; a detection device, which is used to detect the temperature inside the container or on the container wall and use it as the cooking temperature of the cooking appliance; a heating device, which is used to heat the container, and can be electric hot plate heating, electromagnetic heating, or infrared heating; a stirring device: which is used to stir and stir-fry the food in the container.

[0136] As Figure 4 shown, the present invention also proposes a control method for the cooking appliance, including:

[0137] Step 402, control the heating device to work and start timing;

[0138] Step 404, determine whether the food temperature reaches the first preset temperature. If the determination result is yes, execute step 406; otherwise, return to step 402;

[0139] Step 406, determine whether the food temperature reaches the second preset temperature. If the determination result is yes, execute step 408; otherwise, return to step 404;

[0140] Step 408, obtain the temperature rise duration T of the food temperature from the first preset temperature to the second preset temperature;

[0141] Step 410: Determine whether T is less than the first preset duration. If the determination result is yes, execute Step 412; otherwise, execute Step 414;

[0142] Step 412: Control the stirring device to operate at the first stirring speed;

[0143] Step 414: Determine whether T is less than the second preset duration. If the determination result is yes, execute Step 416; otherwise, execute Step 418;

[0144] Step 416: Control the stirring device to operate at the second stirring speed;

[0145] Step 418: Control the stirring device to operate at the third stirring speed.

[0146] In a specific embodiment, under the condition of the same heating power, different food amounts result in different temperature rising situations. For example, when the food amount is small, the temperature rising speed is fast, and in this case, the phenomenon of "bottom burning" is likely to occur; when the food amount is large, the temperature rising speed is slow, and in this case, the temperature rising speed is likely to be slow.

[0147] The cooking appliance proposed in this embodiment is provided with a man-machine interface. The control device can receive parameters such as a cooking start instruction, cooking time, and temperature (specifically, the cooking instruction can be generated by a man-machine interface, an instruction generation device, automatically generated by a microcontroller, or generated by a user-set cooking plan; such as an instruction triggered by a key, a switch, a sound signal, a light signal, an infrared signal, an electromagnetic signal, or a wireless communication signal); when the control device receives the start instruction, the microcontroller controls the heating device to heat, and the temperature detection device detects the food temperature. When the food temperature reaches from the first preset temperature to the second preset temperature, the temperature rising duration T is obtained; if the temperature rising duration T is less than the first preset duration, the control device controls the stirring device to stir at the first stirring speed; if the temperature rising duration T is greater than or equal to the first preset time and less than the second preset duration, the control device controls the stirring device to stir at the second stirring speed; if the temperature rising duration T is greater than or equal to the second preset duration, the control device controls the stirring device to stir at the first stirring speed; when the cooking time reaches the set cooking time, the cooking ends.

[0148] In this embodiment, further, the first stirring speed > the second stirring speed > the third stirring speed. The difference between different stirring speeds can be the difference in the speed of continuous stirring, or the difference in the speed of intermittent stirring, or the difference in the proportion of the stirring time to the total time; the stirring direction can be in the same direction or in two alternating positive and negative directions. Preferably, the stirring is intermittent stirring, which can reduce the heating temperature of the stirring device and extend the service life of the stirring device. Preferably, the stirring direction is in two alternating positive and negative directions to prevent the stirring device from being stuck by food and to make the food stir-fry more evenly.

[0149] In this embodiment, further, the first preset temperature is generally set between 30°C and 50°C, and the second preset temperature is generally set between 80°C and 100°C.

[0150] In this embodiment, further, the first preset duration is generally set between 30 seconds and 2 minutes, and the second preset duration is generally set between 1 minute and 3 minutes.

[0152] As Figure 5 shown, the present invention also proposes a control method for the cooking appliance, including:

[0153] Step 502, control the heating device to work and start timing;

[0154] Step 504, obtain the temperature change amount △T of the food per unit time;

[0155] Step 506, determine whether △T is less than the first change amount threshold. If the determination result is yes, execute step 508; otherwise, execute step 510;

[0156] Step 508, control the stirring device to operate at the fourth stirring speed;

[0157] Step 510, determine whether △T is less than the second change amount threshold. If the determination result is yes, execute step 512; otherwise, execute step 514;

[0158] Step 512, control the stirring device to operate at the fifth stirring speed;

[0159] Step 514, control the stirring device to operate at the sixth stirring speed.

[0160] In a specific embodiment, under the condition of the same heating power, different amounts of food result in different heating situations. For example, when the amount of food is small, the heating speed is fast, and in this case, the phenomenon of "bottom burning" is likely to occur; when the amount of food is large, the heating speed is slow, and in this case, the heating speed is likely to be slow.

[0161] The cooking appliance proposed in this embodiment is provided with a man-machine interface, and the control device can receive parameters such as a cooking start instruction, cooking time, and temperature (specifically, the cooking instruction can be generated by a man-machine interface, an instruction generation device, automatically generated by a microcontroller, or generated by a cooking scheme set by a user; such as an instruction triggered by a key, a switch, a sound signal, a light signal, an infrared signal, an electromagnetic signal, or a wireless communication signal); when the control device receives the start instruction, the microcontroller controls the heating device to heat, and the temperature detection device detects the food temperature; obtain the temperature change amount △T of the food per unit time. If the temperature change amount △T of the food is less than the first change amount threshold, the control device controls the stirring device to stir at the fourth stirring speed; if the temperature change amount △T of the food is less than the second change amount threshold, the control device controls the stirring device to stir at the fifth stirring speed; if the temperature change amount △T of the food is less than the third change amount threshold, the control device controls the stirring device to stir at the sixth stirring speed.

[0162] In this embodiment, further, the fourth stirring speed < the fifth stirring speed < the sixth stirring speed. The difference between different stirring speeds can be the difference in the speed of continuous stirring, the difference in the speed of intermittent stirring, or the difference in the proportion of the stirring time to the total time; the stirring direction can be the same direction or two directions of positive and negative alternation. Preferably, the stirring is intermittent stirring, and the intermittent stirring can reduce the heating temperature of the stirring device and extend the service life of the stirring device. Preferably, the stirring direction is two directions of positive and negative alternation, which is used to prevent the stirring device from being stuck by food and to make the food stir more evenly.

[0163] In this embodiment, further, the first change amount threshold < the second change amount threshold < the third change amount threshold. The above first change amount threshold, second change amount threshold, and third change amount threshold can be designed according to the actual situation. The above first change amount threshold, second change amount threshold, and third change amount threshold can be designed between 30°C and 50°C.

[0164] In this embodiment, further, the unit time can be designed according to the actual situation and can be set between 30 seconds and 2 minutes.
