[0057] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0058] The main solution of the embodiment of the present invention is: when the cooking device is in the heating state, obtain the temperature change parameter of the pot body; when the temperature change parameter meets the abnormal temperature condition, control the cooking device to stop heating.

[0059] In the prior art, during the heating process of the cooking device, food is likely to stick to the components related to heating regulation, affecting the heating regulation performance of the device, and easily causing the cooking device to work in an abnormal state, affecting its service life.

[0060] The present invention provides the above solution to avoid the cooking device from working in an abnormal state and improve the service life of the whole machine.

[0061] The embodiment of the present invention proposes a cooking device. Here, the cooking device specifically refers to a device that can cook food by heating. Specifically, the cooking device can be an electric pressure cooker, a rice cooker, an oven, a microwave oven, etc.

[0062] In the embodiment of the present invention, referring to Figure 1 and Figure 2 , the cooking device includes a pot body 1, a heating device 2, a temperature sensor 3 and a control device. Among them, the heating device 2 is used to heat the pot body 1, and the temperature sensor 3 is used to detect the temperature of the pot body 1.

[0063] In this embodiment, the heating device 2 is arranged below the pot body 1. In addition, in other embodiments, the heating device 2 can also be arranged on the side of the pot body 1 or surround the entire outer wall of the pot body 1. The heating device 2 includes a coil assembly 21, which generates heat when the coil assembly 21 is powered on to heat the pot body 1; and stops heating the pot body 1 when the coil assembly 21 is powered off. Specifically, in this embodiment, the heating device 2 further includes a mounting seat 22, the mounting seat 22 is located at the bottom of the pot body 1, the mounting seat 22 is formed with a mounting groove, and the coil assembly 21 is arranged in the mounting groove and is spaced from the pot body 1.

[0064] Referring to Figure 1 and Figure 2 , the temperature sensor 3 can be arranged on the pot body 1 or on a structural member in contact with the pot body 1. Specifically, in this embodiment, the above-mentioned mounting seat 22 includes a boss 221 abutting against the pot body 1, and the temperature sensor 3 is clamped between the pot body 1 and the boss 221 to detect the temperature of the pot body 1 in the heating state. Among them, the coil assembly 21 can be arranged around the boss 221 here. Among them, in addition to the temperature sensor 3, a fuse assembly 6 connected to the coil assembly 21 is also arranged on the boss 221 to fuse when the heating temperature is too high and trigger the coil assembly 21 to stop heating.

[0065] In the embodiment of the present invention, referring to Figure 3, the temperature sensor 3 and the heating device 2 are both connected to the control device. The control device includes: a processor 1001 (such as a CPU), a memory 1002, etc. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0066] Those skilled in the art can understand that Figure 3 the device structure shown in

[0067] does not constitute a limitation on the device, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. Figure 3 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for the cooking device. In the device shown in Fig. 3, the processor 1001 can be used to call the control program for the cooking device stored in the memory 1002 and perform the relevant step operations of the control method for the cooking device in the following embodiments.

[0068] Further, referring to Figure 1 , the cooking device further includes a stirring assembly 4 and a stirring motor 5. The bottom of the pot body 1 is provided with a first through hole. The stirring assembly 4 is located inside the pot body 1. One end of the stirring assembly 4 passes through the first through hole and is in transmission connection with the stirring motor 5. When food is loaded in the pot body 1, the stirring motor 5 is turned on, and the stirring assembly 4 can be driven to stir the food in the pot body 1. Among them, when the stirring motor 5 is turned on, the heating device 2 can be in an on or off state. Specifically, the stirring motor 5 can be located below the heating device 2. The heating device 2 (such as the boss 221 above) can be provided with a second through hole. The output shaft of the stirring motor 5 can pass through the second through hole and be connected to one end of the stirring assembly 4 passing through the first through hole.

[0069] Further, referring to Figure 1 and Figure 2 , the cooking device further includes a housing 7. The above-mentioned pot body 1 is detachably connected to the housing 7. Specifically, the above-mentioned stirring motor 5 can be fixed to the bottom of the housing 7 through a motor bracket 8. The mounting seat 22 is fixed above the motor bracket 8. The pot body 1 is detachably mounted above the mounting seat 22. Among them, when the pot body 1 is separated from the housing 7, the bottom of the pot body 1 is separated from the boss 221 of the mounting seat 22, and the stirring assembly 4 in the pot body 1 is separated from the stirring motor 5; when the pot body 1 is installed in the housing 7, the bottom of the pot body 1 abuts against the boss 221 of the mounting seat 22. The temperature sensor 3 on the boss 221 contacts the outer wall of the pot body 1, and the stirring assembly 4 in the pot body 1 is connected to the stirring motor 5.

[0070] When the cooking device is provided with a stirring component 4 passing through the pot body, the abnormal temperature during its heating process may be caused by food in the pot body 1 leaking from the through hole through which the stirring component 4 passes to the lower part of the pot body 1, causing foreign matters to adhere to the temperature control elements (such as the temperature sensor 3, the fuse component 6, etc.) on the mounting base 22. It may also be caused by foreign matters falling into the housing 7 and standing on the temperature control element and / or the coil assembly 21 after the pot body 1 is separated from the housing 7. Based on this, the control method of the cooking device can effectively solve the problem of abnormal heating operation of the cooking device caused by the cooking device provided with the stirring component 4.

[0071] An embodiment of the present invention also provides a control method for a cooking device to control the operation of the above cooking device.

[0072] Referring to Figure 4 , an embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, the control method of the cooking device includes:

[0073] Step S10, when the cooking device is in the heating state, obtain the temperature change parameter of the pot body;

[0074] The heating state of the cooking device specifically refers to the state where the heating device is turned on and heats the pot body. Specifically, the heating state can be started when a specific instruction input by the user is detected, or can be automatically turned on when the state of the pot body (such as the state of the loaded food or the placement state of the pot body) reaches the set condition or the operating parameters of the cooking device reach the set condition.

[0075] The temperature change parameter specifically represents the parameter of the temperature change of the pot body in the heating state. The temperature change parameter specifically includes the temperature change amplitude, the temperature change rate, and / or the temperature change curve, etc. In the heating state, the temperature data detected by the temperature sensor can be obtained in real time or at intervals of a set duration, and the temperature change parameter here can be determined according to the obtained temperature data.

[0076] Step S20, determine whether the temperature change parameter meets the abnormal temperature condition;

[0077] When the temperature change parameter meets the abnormal temperature condition, execute step S30.

[0078] Step S30, control the cooking device to stop heating.

[0079] The abnormal temperature condition is specifically set in advance according to the temperature change characteristics of the cooking utensil during the abnormal working state or the normal working state of the cooking device. The abnormal temperature condition can be the target interval range that the temperature change parameters need to reach under the abnormal working state of the cooking device, or the target relationship that the quantitative relationship (such as the magnitude relationship, deviation value, etc.) between the temperature change parameters and the preset threshold needs to reach under the abnormal working state of the cooking device.

[0080] The abnormal temperature condition can be a fixed parameter set in advance, or a parameter that adaptively changes according to the different usage states of the cooking device. For example, different cooking parameters can correspond to different abnormal temperature conditions.

[0081] When the temperature change parameter meets the abnormal temperature condition, it can be considered that there is an abnormality in the current heating process of the cooking device. At this time, the cooking device can be controlled to stop heating.

[0082] A control method for a cooking device proposed in an embodiment of the present invention monitors the temperature change parameters of the cooking utensil when the cooking device is in the heating state. When the temperature change parameter meets the abnormal temperature condition, the cooking device is controlled to stop heating. The abnormality of the operation of the cooking device is identified through the temperature change of the cooking utensil, and heating is stopped when an abnormality is found, which can effectively prevent the cooking device from working in an abnormal state and improve the service life of the whole machine.

[0083] Further, when the temperature change parameter meets the abnormal temperature condition, in addition to controlling the cooking device to stop heating, a prompt message can also be output to prompt the user to check whether there is an abnormality in the current cooking device, so that the user can discover and handle the abnormality of the cooking device in time, ensuring that the cooking device can meet the cooking needs of the user. The prompt message can be in the form of a text prompt, a sound prompt, a light prompt, and / or pushing a message to the user terminal, etc.

[0084] After the prompt message is output, the cooking device can be controlled to operate according to the information fed back by the user. For example, when receiving the information fed back by the user that there is no abnormality, the cooking device can be controlled to continue heating. Further, since the cooking device is provided with a stirring component passing through the cooking utensil, the abnormal temperature during its heating process may be caused by the food in the cooking utensil leaking from the through hole through which the stirring component passes to the lower part of the cooking utensil, causing foreign matters to adhere to the temperature control elements (such as temperature sensors, fuses, etc.) on the mounting seat, or may be caused by foreign matters falling into the housing after the cooking utensil is separated from the housing and standing on the temperature control elements and / or the coil assembly. Based on this, a prompt message can be output to prompt the user to take out the cooking utensil from the cooking device and check for foreign matters. Specifically, after the prompt message is output, if the action of taking out and reinserting the cooking utensil from the cooking device is detected, it can be considered that the user has completed the abnormality check. At this time, the cooking device can be controlled to continue heating.

[0085] Further, based on the above embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, referring to Figure 5 after step S10, it further includes: when the temperature change parameter does not satisfy the abnormal temperature condition, step S40 is executed.

[0086] Step S40, obtaining the heating duration of the cooking device;

[0087] The heating duration here specifically refers to the continuous duration after the cooking device starts the heating state.

[0088] Step S50, determining whether the heating duration is less than a preset cooking duration;

[0089] When the heating duration is less than the preset cooking duration, step S60 is executed and step S10 is returned to for execution; when the heating duration is greater than or equal to the preset cooking duration, step S70 is executed.

[0090] Step S60, controlling the cooking device to maintain heating;

[0091] Step S70, controlling the cooking device to stop heating.

[0092] The preset cooking duration is specifically the target duration required for the cooking device to heat up as set in advance. The preset cooking duration can be a parameter set by the user or a parameter set by default in the system.

[0093] Specifically, the preset cooking duration can be determined based on the cooking type currently executed by the cooking device. Different cooking types correspond to different preset cooking durations. For example, the steaming function and the soup - making function correspond to different preset cooking durations respectively.

[0094] When the heating duration is less than the preset cooking duration, it can be considered that the ingredients in the cooking device still need to be heated to meet the cooking requirements; when the heating duration is greater than or equal to the preset cooking duration, it can be considered that the ingredients in the cooking device already meet the cooking requirements and do not need to be heated continuously.

[0095] In this embodiment, through the above steps S40 to S70, the cooking device can continuously monitor whether there is an abnormality in its working state before the cooking ends, so as to ensure that the heating is stopped in time when there is an abnormality, and further extend the service life of the cooking device.

[0096] Further, based on the above embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, referring to Figure 6 , step S10 includes:

[0097] Step S11: When the cooking device is in the heating state, obtain multiple target temperatures of the pot body, and the multiple target temperatures are detected at different times respectively.

[0098] The target temperature here can be all the temperatures of the pot body detected by the temperature sensor after the cooking device starts heating; in addition, it can also be the temperatures that meet the specified conditions among all the temperatures of the pot body detected by the temperature sensor after the cooking device starts heating. For example, multiple temperatures of the pot body detected by the temperature sensor within a preset time period after starting heating can be used as the multiple target temperatures here; all the temperature values during the heating-up process after starting heating can be used as the multiple target temperatures here; when the heating device is intermittently turned on in the heating state, all the temperature values during the cooling process can also be used as the target temperatures here.

[0099] Specifically, since if there is an abnormality during the temperature rise stage of the cooking device during the heating process, it is likely to cause the overall temperature of the cooking device to be too high and affect its lifespan. Based on this, step S11 here may specifically include: after the cooking device starts heating, detect multiple temperature values of the pot body; if the change trend corresponding to the multiple temperature values is a temperature rise, then determine the temperature value as the target temperature. Specifically, define two adjacent temperature values at the detection times as the first temperature value and the second temperature value respectively. If the first temperature value is greater than the second temperature value, it can be considered that the change trend is a temperature drop; if all the second temperature values are greater than their corresponding first temperature values, it can be considered that the change trend is a temperature rise. Among them, when there are multiple temperature rise processes during the heating process of the cooking device, the target temperature is the temperature value of the pot body detected during the first temperature rise process. Here, taking the temperature of the pot body during the temperature rise process of the cooking device as the target temperature can ensure that the cooking device does not operate under a state of too high temperature, which is beneficial to extending the service life of the cooking device.

[0100] Step S12: Determine the temperature change curve of the pot body according to the multiple target temperatures and their corresponding detection times.

[0101] The temperature change curve is specifically a characteristic parameter representing the change of the pot body temperature over time. Specifically, draw the temperature change curve here with time as the abscissa and temperature as the ordinate.

[0102] Step S13: Determine the temperature change parameter according to the temperature change curve.

[0103] Specifically, the temperature change curve can be directly used as the temperature change parameter; or the curve characteristic parameters (such as slope, extreme value, and / or curve type, etc.) of the temperature change curve can be further extracted as the temperature change parameter here.

[0104] Among them, when the temperature change parameter is a temperature change curve, a preset temperature curve of the cooking device in the normal operation state can be obtained, and the temperature change curve is compared with the preset temperature curve. If the deviation characteristic parameter is less than or equal to the set threshold, it can be considered that the temperature change parameter does not meet the abnormal temperature condition, and at this time, the cooking device can maintain heating; if the deviation characteristic parameter is greater than the set threshold, it can be considered that the temperature change parameter meets the abnormal temperature condition, and at this time, the cooking device can stop heating.

[0105] In addition, when the temperature change parameter is a curve characteristic parameter, a preset curve parameter of the temperature change curve of the cooking device in the normal operation state can be obtained, and the current curve characteristic parameter is compared with the preset curve parameter. If the two parameters match, it can be considered that the temperature change parameter does not meet the abnormal temperature condition, and at this time, the cooking device can maintain heating; if the two parameters do not match, it can be considered that the temperature change parameter meets the abnormal temperature condition, and at this time, the cooking device can stop heating.

[0106] In this embodiment, the temperature change curve generated by the pot body temperature detected at multiple different moments in the heating state is used as a characteristic parameter for identifying whether the cooking device has an abnormal working state. The temperature change curve of the pot body in the heating state can be accurately characterized, so as to accurately identify the abnormal state of the cooking device, which is beneficial to stopping heating in time and extending the service life of the cooking device.

[0107] Further, in this embodiment, step S13 includes: determining the slope of the temperature change curve; determining the slope as the temperature change parameter.

[0108] The slope of the temperature change curve here can characterize the change speed of the pot body temperature during the heating process. If the change is too slow, it is easy to cause the pot body not to be heated to the temperature required for cooking. If the change is too fast, it is easy to cause the pot body temperature to be too high. Based on this, taking the slope of the temperature change curve as the temperature change parameter here can accurately characterize the working state during the heating process of the cooking device, and can identify the abnormal working state of the cooking device in time and accurately based on the slope, and stop heating in time in the abnormal working state. Among them, when judging whether the curve slope meets the abnormal temperature condition with the standard slope interval in the normal working state as the judgment benchmark, when the slope is within the standard slope interval, it is considered that the cooking device is in the normal working state, and when the slope is outside the standard slope interval, it is considered that the cooking device is in the abnormal working state, which can ensure that the cooking device will not operate in a state of too high or too low temperature, and can ensure that the cooking device can meet the user's cooking needs while extending its service life.

[0109] Among them, to calculate the tangent slopes of multiple points corresponding to the temperature change curve, the average value of multiple tangent slopes can be used to represent the slope of the temperature change curve; or the temperature change interval can be divided into multiple sub-curves based on different preset heating durations, and corresponding preset weights can be obtained based on the preset heating duration corresponding to each sub-curve. The sub-tangent slopes of each sub-curve are calculated respectively, and a weighted average calculation is performed according to each sub-tangent slope and its corresponding weight. The obtained result represents the slope of the temperature change curve. Among them, each preset heating duration is timed from the start of heating, and the longer the preset heating duration, the greater the corresponding preset weight. Based on this, abnormal judgment based on the slope of the temperature change curve can further ensure that the overall temperature of the machine will not be too high, and further extend the service life of the cooking device.

[0110] Further, based on any of the above embodiments, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, referring to Figure 7 , the step S20 includes:

[0111] Step S21, determining whether the temperature change parameter is within the preset parameter interval corresponding to the normal working state;

[0112] When the temperature change parameter is outside the preset parameter interval corresponding to the normal working state, step S22 is executed; when the temperature change parameter is within the preset parameter interval, step S23 is executed.

[0113] Step S22, determining that the temperature change parameter satisfies the abnormal temperature condition;

[0114] Step S23, determining that the temperature change parameter does not satisfy the abnormal temperature condition;

[0115] Among them, the preset parameter interval has an upper limit value and a lower limit value. Here, the lower limit value of the preset parameter interval can be determined according to the minimum temperature required for cooking, and the upper limit value of the preset parameter interval can be determined according to the maximum temperature allowed for the normal use of the cooking device.

[0116] The type of the preset parameter interval changes according to the type change of the temperature change parameter. For example, when the temperature change parameter is the temperature change amplitude, the preset parameter interval is the preset amplitude interval; when the temperature change parameter is the temperature change rate, the preset parameter interval is the preset rate interval.

[0117] In this embodiment, the temperature change parameter is the slope of the above temperature change curve. Based on this, the preset parameter range is the preset slope range. Specifically, the minimum slope and the maximum slope allowed for the slope of the temperature change curve of the cooking device in the normal working state can be determined through big data analysis or empirical analysis, and the determined minimum slope and maximum slope are used as the two critical values of the preset slope range. If the slope of the temperature change curve in the current heating state is within the preset slope range, it does not meet the abnormal temperature condition, and it can be considered that the cooking device is currently in the normal working state; if the slope of the temperature change curve in the current heating state is outside the preset slope range, it meets the abnormal temperature condition, and it can be considered that the cooking device is currently in the abnormal working state.

[0118] In this embodiment, whether the cooking device is working abnormally is identified by whether the temperature change parameter is within the preset parameter range with an upper limit value and a lower limit value, which is beneficial to ensure that the heating temperature of the cooking device during the heating state is neither too high nor too low, and while ensuring that the cooking device can meet the cooking requirements, its service life is extended.

[0119] Further, based on any of the above embodiments, before step S20, the following is further included:

[0120] Step S101, obtaining the cooking characteristic parameters of the cooking device;

[0121] The cooking characteristic parameters specifically refer to the parameters related to cooking operations. The cooking characteristic parameters specifically include the cooking operation type, the cooking food type, the cooking duration, and / or the cooking temperature, etc.

[0122] Specifically, in this embodiment, step S01 includes: obtaining the cooking operation type and / or the cooking food type of the cooking device; determining the cooking operation type and / or the cooking food type as the cooking characteristic parameters. Among them, the cooking operation type specifically includes cooking rice, making soup, baking, etc. The cooking food type specifically includes solid ingredients and liquid ingredients.

[0123] Step S102, obtaining the abnormal temperature condition according to the cooking characteristic parameters;

[0124] Among them, different cooking characteristic parameters correspond to different abnormal temperature conditions.

[0125] The abnormal temperature conditions corresponding to different cooking characteristic parameters are different.

[0126] In this embodiment, the abnormal temperature condition is that the above temperature change parameter is outside the preset parameter range. Different types of cooking operations may correspond to different preset parameter ranges. For example, the slope within the preset slope range corresponding to cooking rice is less than the slope within the preset slope range corresponding to baking. Different types of cooking foods may also correspond to different preset parameter ranges. For example, the slope within the preset slope range corresponding to a solid cooking ingredient type is greater than the slope within the preset slope range corresponding to a liquid cooking ingredient type.

[0127] In this embodiment, based on the cooking characteristic parameters of the cooking device, a preset temperature condition for determining whether the device has an abnormal working condition is obtained, so as to ensure that when the cooking device is in different cooking functions, the abnormal condition of the cooking device in the current working state can be accurately identified by comparing the temperature change parameter with the abnormal temperature condition, ensuring that the cooking device can meet diverse cooking requirements while extending its service life.

[0128] Among them, the execution sequence of step S101 and step S102 here and the above step S10 is not specifically limited, and they can be executed successively or synchronously according to actual needs.

[0129] Further, based on any of the above embodiments, before step S10, it further includes:

[0130] Step S01, controlling the cooking device to perform a stirring operation, and stirring the ingredients in the pot body when the stirring operation is executed;

[0131] When the cooking device performs the stirring operation, the stirring motor starts to run, driving the stirring component in the pot body to rotate to stir the ingredients in the pot body.

[0132] Step S02, if the stirring operation reaches the preset stirring condition, then execute step S10.

[0133] The preset stirring condition here can be set according to the actual situation, and can be the target number of times, target duration, and / or target direction required for stirring, etc. Specifically, in this embodiment, when the number of operations corresponding to the stirring operation is greater than or equal to the preset number of times, or when the operation time corresponding to the stirring operation is greater than or equal to the preset duration, it is determined that the stirring operation reaches the preset stirring condition. The specific values of the preset number of times and the preset duration can be set according to the actual situation. The preset number of times and the preset duration can be parameters set by the user, or can also be parameters preset in the air conditioning system. For example, when the running duration of the stirring motor reaches more than 1 s or rotates at least once after starting, it can be considered that the stirring operation reaches the preset stirring condition.

[0134] Specifically, before the heating device of the cooking device starts heating, the cooking device can be controlled to perform a stirring operation first. When the stirring operation reaches the preset stirring condition, the heating device is controlled to start heating and step S10 is executed. In the heating state, the cooking device can stop the stirring operation or maintain the execution of the stirring operation.

[0135] In this embodiment, after the stirring operation reaches the preset stirring condition, the abnormal conditions of the cooking device in the heating state are monitored, so as to ensure that the monitoring based on the pot body temperature change parameters can timely detect the working abnormality caused by the leakage of ingredients during the stirring process, and further avoid the pot body working in the state of abnormal temperature, realizing further extension of the service life of the cooking device.

[0136] Further, in this embodiment, the cooking device further includes a housing, and the pot body is detachably connected to the housing. Before the step of controlling the cooking device to perform the stirring operation, it further includes: obtaining the placement state information of the pot body; when the placement state information is that the pot body has been placed on the housing, execute the step of controlling the cooking device to perform the stirring operation; when the placement state information is that the pot body is not placed on the housing, a corresponding prompt message is output. Specifically, the placement state information of the pot body can be detected after the cooking device is powered on or after receiving a user instruction. Here, the pot body is specifically a container for loading food. After ensuring that the pot body is placed on the cooking device, the cooking device can be controlled to perform the stirring operation. When the stirring operation reaches the preset stirring condition, the cooking characteristic parameters set by the user can be obtained, and the cooking device is controlled to perform the corresponding cooking operation according to the obtained cooking characteristic parameters. When the cooking operation is an operation that needs to heat the food, the heating device can be controlled to start heating and step S10 is executed.

[0137] In this embodiment, ensuring that the pot body is placed on the housing before starting the stirring function can ensure the effectiveness of the stirring function execution of the cooking device.

[0138] Further based on any of the above embodiments, after step S30 above, it may further include:

[0139] Step S301, when the heating device runs to reach the preset abnormal condition, adjust the rated temperature of the heating device;

[0140] During the cooking operation of the cooking device, the heating device can be turned on to heat the items in the pot body. When the heating device is in the on state, the operating parameters of the heating device itself can be monitored, or the temperature characteristic parameters (such as temperature values, temperature change parameters, etc.) of the pot body heated by the heating device can be monitored. When the monitored parameters reach the parameter range corresponding to the preset abnormal operation, it can be considered that the heating device has reached the preset abnormal condition; otherwise, it can be considered that the heating device is in the normal operating state. In addition, or when the heating device is in the on state, if a setting instruction input by the user is received, it can be considered that the heating device has reached the preset abnormal condition; otherwise, it can be considered that the heating device is in the normal operating state.

[0141] The rated temperature is specifically the temperature used to control the operation of the heating device. The rated temperature is a parameter specifically pre-stored in the memory of the cooking device. It can be the parameter stored before the cooking device leaves the factory, or it can be the temperature re-stored after adjusting the control temperature stored before leaving the factory after the cooking device leaves the factory. For example, the temperature stored after adjusting the current rated temperature when the heating device last reached the preset abnormal condition is used as the rated temperature here.

[0142] When it is determined that the heating device has reached the preset abnormal condition, there is an abnormality in the heating of the heating device. At this time, the corresponding rated temperature of the heating device can be adjusted. This adjustment can increase the rated temperature or decrease the rated temperature. Specifically, the adjustment direction of the rated temperature can be determined according to the current abnormal type of the heating device or the type of protection requirements.

[0143] Step S302, control the operation of the heating device according to the adjusted rated temperature to limit the heating temperature of the cooking device within the target temperature range.

[0144] The control methods for the operation of the heating device here include but are not limited to turning on the heating device, turning off the heating device, decreasing or increasing the heating power of the heating device, etc.

[0145] The target temperature range is specifically the temperature range that the heating temperature of the cooking device needs to reach during normal operation. The target temperature range can have an upper limit value and a lower limit value, or it can only have an upper limit value or a lower limit value. The maximum critical value of the target temperature range is greater than or equal to the rated temperature. The lower limit value here can be determined according to the minimum temperature required for cooking, and the upper limit value can be determined according to the maximum temperature allowed for normal use of the cooking device.

[0146] Specifically, the heating temperature of the cooking device can be obtained (which can be determined based on the current operating parameters of the cooking device or characterized by the temperature of the pot body, etc.), the heating temperature is compared with the rated temperature, and the control method of the heating device is determined based on the comparison result.

[0147] In this embodiment, when the heating device malfunctions, the rated temperature corresponding to the heating device is reduced, and the heating device is controlled to operate according to the reduced rated temperature, so as to limit the heating temperature of the cooking device within a target temperature range. During this process, the temperature control parameters of the cooking device are no longer fixed, but can be adjusted when the heating device malfunctions. Based on this, even if the heating device malfunctions, the adjustment of the rated temperature can be used to prevent the temperature of the cooking device from exceeding the normal range, thereby improving the accuracy of temperature control of the cooking device and extending the service life of the cooking device.

[0148] In this embodiment, step S302 includes: obtaining the current temperature of the pot body; if the current temperature is greater than or equal to the adjusted rated temperature, controlling the heating device to turn off; if the current temperature is less than the adjusted rated temperature, controlling the heating device to turn on. Here, based on the magnitude relationship between the current temperature of the pot body and the rated temperature, the turning on and off of the heating device are controlled, so as to achieve precise heating control, avoid abnormal operation of the cooking device at too high a temperature while meeting the cooking requirements, and effectively extend the service life of the cooking device.

[0149] Further, in the above step S301, another embodiment of the control method of the cooking device of the present application is proposed. In this embodiment, the heating temperature of the cooking device decreases as the rated temperature decreases. In the step S301, the step of adjusting the rated temperature corresponding to the heating device includes:

[0150] Reducing the rated temperature corresponding to the heating device.

[0151] Here, the temperature adjustment parameter of the rated temperature can be a preset fixed adjustment parameter or a temperature adjustment parameter determined based on the actual operating conditions of the heating device.

[0152] For example, the preset temperature adjustment parameter is ΔT, and the rated temperature is defined as T rated, then the reduced rated temperature can be T rated - ΔT.

[0153] Here, when the heating device malfunctions, by reducing the rated temperature, the heating temperature of the heating device can be reduced, which can effectively prevent the heating temperature from being too high due to foreign objects such as food sticking to the temperature control components (such as temperature sensors, fuse components, etc.) of the cooking device, thereby affecting the service life of the cooking device, effectively avoiding the temperature of the cooking device from being too high, improving the accuracy of temperature control of the cooking device, and extending the service life of the cooking device.

[0154] It should be noted that in other embodiments, when the abnormal operation of the heating device is caused by too low heating temperature, adjusting the rated temperature of the heating device may also be to increase the corresponding rated temperature of the heating device, so as to control the heating device based on the increased rated temperature to increase the heating temperature of the heating device.

[0155] Further, the heating temperature of the cooking device decreases as the rated temperature decreases. In this embodiment, the steps of reducing the rated temperature corresponding to the heating device include:

[0156] Step S301a, obtaining the temperature characteristic parameters of the pot body when the heating device operates abnormally;

[0157] The temperature characteristic parameters here can be the temperature value of the pot body and / or temperature change parameters (such as temperature change curve, temperature change amplitude, and / or temperature change rate, etc.).

[0158] Specifically, the temperature characteristic parameters here can be obtained from the temperature value or temperature change parameters of the pot body detected when receiving the setting instruction corresponding to the preset abnormal condition. In addition, the temperature value or temperature change parameters of the pot body can also be continuously monitored during the operation of the heating device. If the monitored temperature characteristic parameters reach the above-mentioned preset abnormal condition, they are used as the temperature characteristic parameters here.

[0159] Step S301b, determining the deviation amount between the temperature characteristic parameters and the critical value of the preset parameter interval; the preset parameter interval is the target interval that the temperature of the pot body needs to reach when the heating device operates normally;

[0160] The preset parameter interval here is the same concept as the preset parameter interval in the above embodiment. The specific type of the preset parameter interval varies according to the type of the temperature characteristic parameters. For example, when the temperature characteristic parameter is the temperature value, the preset parameter interval is the preset temperature interval; when the preset characteristic parameter is the temperature change parameter, the preset parameter interval is the preset change interval corresponding to the temperature. Specifically, in this embodiment, the preset characteristic parameter can be the slope of the temperature change curve corresponding to the pot body, and the preset change interval can be the preset slope interval corresponding to the normal operation of the cooking device.

[0161] The preset parameter interval can have both an upper limit value and a lower limit value, or can have only an upper limit value or a lower limit value.

[0162] Specifically, in this embodiment, the preset parameter interval has an upper limit value and a lower limit value. When the temperature characteristic parameter is greater than the upper limit value of the preset parameter interval, the absolute value of the difference between the upper limit value and the temperature characteristic parameter is used as the deviation amount here; when the temperature characteristic parameter is less than the lower limit value of the preset parameter interval, the absolute value of the difference between the lower limit value and the temperature characteristic parameter is used as the deviation amount here.

[0163] Step S301c, determine a temperature adjustment parameter according to the deviation amount;

[0164] Different deviation amounts correspond to different temperature adjustment parameters. The temperature adjustment parameter may specifically include a temperature adjustment amplitude, a temperature adjustment rate, and / or a temperature adjustment ratio, etc. The correspondence between the deviation amount and the temperature adjustment parameter may be preset, and may be a calculation relationship, a mapping relationship, an algorithm model, etc. Based on the preset correspondence, the temperature adjustment parameter corresponding to the current deviation amount can be determined.

[0165] Specifically, in this embodiment, in order to ensure that under the adjusted rated temperature, the heating temperature of the cooking device can be accurately limited, and to ensure that the cooking device heats under normal conditions, the temperature adjustment parameter increases with the increase of the deviation amount. For example, the larger the deviation amount, the greater the adjustment amplitude of the rated temperature; or, the larger the deviation amount, the greater the adjustment rate of the rated temperature.

[0166] Step S301d, reduce the rated temperature according to the temperature adjustment parameter.

[0167] In this embodiment, based on the deviation amount between the temperature characteristic parameter during the abnormal operation of the heating device and the critical value of the preset parameter range, the corresponding temperature adjustment parameter is determined to adjust the rated temperature, which can ensure the accuracy of the rated temperature adjustment, and ensure that based on the adjusted rated temperature to control the operation of the heating device, the heating temperature of the cooking device can be accurately limited within the target temperature range.

[0168] Further, in this embodiment, step S301c includes:

[0169] Obtain the current cooking characteristic parameter of the cooking device; obtain the target correspondence according to the cooking characteristic parameter; determine the temperature adjustment parameter corresponding to the deviation amount based on the target correspondence.

[0170] The cooking characteristic parameter specifically refers to a parameter related to cooking operations. The cooking characteristic parameter specifically includes a cooking operation type, a cooking food type, a cooking duration, and / or a cooking temperature, etc.

[0171] Specifically, in this embodiment, obtain the cooking operation type and / or the cooking food type of the cooking device; determine the cooking operation type and / or the cooking food type as the cooking characteristic parameter. Among them, the cooking operation type specifically includes cooking rice, making soup, baking, etc. The cooking food type specifically includes solid ingredients and liquid ingredients.

[0172] The target correspondence specifically refers to the correspondence between the deviation amount currently used to determine the temperature adjustment parameter and the temperature adjustment parameter.

[0173] There can be multiple preset corresponding relationships between the deviation amount and the temperature adjustment parameter. The same deviation amount can correspond to different temperature adjustment parameters based on different corresponding relationships. Among them, each corresponding relationship can correspond to different cooking characteristic parameters. Based on this, one corresponding relationship can be determined from multiple preset corresponding relationships as the target corresponding relationship based on the current cooking characteristic parameters.

[0174] In this embodiment, by combining the current cooking characteristic parameters of the cooking device and the deviation amount to determine the temperature adjustment parameter, the adjustment of the rated temperature can be realized more accurately, ensuring that the heating process of the cooking device can be further accurately controlled based on the rated temperature, so as to avoid the cooking device working in an abnormal state and effectively extend its service life.

[0175] In addition, an embodiment of the present invention also provides a computer-readable storage medium, on which a control program of the cooking device is stored. When the control program of the cooking device is executed by a processor, the relevant steps of any one of the above embodiments of the control method of the cooking device are realized.

[0176] It should be noted that in this article, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or system including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or system.
