Description

Technical Field

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

[0002] Currently, cooking appliances require a processing unit in some menus to process food in a pot. However, if the user does not install the processing unit on the driving unit, normal cooking effects may be affected. Summary of the invention

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

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

[0005] A second aspect of the present invention also provides a cooking appliance.

[0006] The third aspect of the present invention also provides a control device for a cooking appliance.

[0007] A fourth aspect of the present invention also provides an electronic device.

[0008] The fifth aspect of the present invention also provides a readable storage medium.

[0009] A sixth aspect of the present invention also provides a cooking utensil.

[0010] In view of this, a first aspect of the present invention proposes a control method for a cooking appliance, which is used for the cooking appliance. The cooking appliance includes a pot body, a processing unit and a driving unit, at least a part of the processing unit extends into the pot body, and the driving unit is used to drive the processing unit to move. The control method includes: responding to a target cooking instruction, obtaining operating parameters of the driving unit and temperature rise parameters in the pot body; determining the connection status of the processing unit and the driving unit according to the operating parameters and the temperature rise parameters.

[0011] The control method of a cooking appliance provided by the present invention is used for a cooking appliance, wherein the cooking appliance comprises a pot body, a processing unit at least partly arranged in the pot body, and a driving unit for driving the processing unit to move. When the processing unit is installed on the driving unit, the movement of the processing unit can be achieved by driving the driving unit, thereby achieving the processing of food in the pot body. The control method of the cooking appliance comprises: responding to a target cooking instruction, obtaining a temperature rise parameter in the pot body and an operating parameter of the driving unit, and jointly determining whether the processing unit and the driving unit are connected according to the temperature rise parameter in the pot body and the operating parameter of the driving unit, thereby improving the accuracy of detecting the installation status and fault condition of the processing unit. Among them, the operating parameters of the driving unit can reflect the connection status of the driving unit and the processing unit, and the temperature rise parameters in the pot body can reflect whether food is placed in the pot body. The operating parameters of the driving unit are different when food is placed in the pot body and when food is not placed in the pot body. In addition, when the driving unit is not connected to the processing unit and when the driving unit is connected to the processing unit but food is not placed in the pot body, the operating parameters of the driving unit are very different, which makes it easy to misjudge the connection status of the driving unit and the processing unit. Therefore, the technical solution proposed in the present application determines whether the processing unit is installed on the driving unit through the operating parameters of the driving unit and the temperature rise parameters in the pot body, thereby ensuring the accuracy of the detection.

[0012] The control method of the cooking appliance provided by the present invention may also have the following additional technical features:

[0013] In some possible designs, the step of determining the connection status of the processing unit and the driving unit based on the operating parameters and the temperature rise parameters specifically includes: when the operating parameters are less than or equal to the first parameter threshold and greater than the second parameter threshold, based on the temperature rise parameter being less than or equal to the temperature rise threshold, determining that the processing unit and the driving unit are in a disconnected state, and issuing a first prompt message.

[0014] In this design, in the step of determining whether the driving part and the processing part are installed according to the temperature rise parameter and the operating parameter, it specifically includes: if the operating parameter of the driving part is less than or equal to the first parameter threshold and greater than the second parameter threshold, the temperature rise parameter of the food in the pot is judged. When the temperature rise parameter is less than or equal to the temperature rise threshold, it means that the temperature rise speed in the pot is slow, which further reflects that food is placed in the pot. In this case, if the processing part is installed on the driving part, the processing of the food by the processing part will be hindered, so the operating parameter will increase. If the operating parameter of the driving part is less than or equal to the first parameter threshold and greater than the second parameter threshold, it means that the load is not connected to the driving part, that is, the processing part is not connected to the driving part, and then a first prompt message is issued to remind the user that the processing part is not installed on the driving part, so that the user can install it as soon as possible to avoid affecting the cooking effect.

[0015] In some possible designs, when the temperature rise parameter is greater than the temperature rise threshold, it is determined that no food is placed in the pot, and a second prompt message is issued.

[0016] In this design, when the temperature rise parameter is greater than the temperature rise threshold, it means that the temperature rise in the pot is relatively fast, which means that no food is placed in the pot. In this case, a second prompt message is issued to remind the user that there is no food in the pot, which makes it easier for the user to re-place the food and avoid danger.

[0017] In some possible designs, before the step of obtaining the temperature rise parameters in the pot body, it also includes: obtaining the operating time of the driving unit; when the operating time is greater than or equal to the first time threshold, based on the operating parameter being less than the second parameter threshold, determining that the driving unit is faulty and issuing a third prompt message.

[0018] In this design, before obtaining the temperature rise parameters in the pot body, it also includes: obtaining the operating time of the driving unit, and when the operating time of the driving unit reaches a first time threshold, judging the size of the operating parameter of the driving unit and the second parameter threshold. If the operating parameter of the driving unit is less than the second parameter threshold, it means that the operating parameter of the driving unit is too small, that is, the driving unit is not working or is damaged. Therefore, it is determined that the driving unit has a fault, and a third prompt message is sent to the user to let the user know the fault of the driving unit for easy maintenance.

[0019] In some possible designs, the control method of the cooking appliance also includes: when the operating parameter is greater than or equal to a second parameter threshold, based on the operating time being greater than or equal to the second time threshold, judging the size of the operating parameter and the first parameter threshold; the second time threshold is greater than or equal to the first time threshold.

[0020] In this design, the control method of the cooking appliance further includes: if the operating parameter of the driving unit is greater than or equal to the second parameter threshold, then judging whether the operating time of the driving unit reaches the second time threshold, if the operating time of the driving unit reaches the second time threshold, then preliminarily judging the connection state between the processing unit and the driving unit according to the magnitude of the operating parameter of the driving unit and the first parameter threshold, specifically, within the second time threshold, if the operating parameter of the driving unit is greater than or equal to the second parameter threshold and less than the first parameter threshold, then preliminarily judging that the processing unit and the driving unit are not connected, and then controlling the cooking appliance to obtain the temperature rise parameter in the pot body, and further judging whether the processing unit is connected to the driving unit according to the temperature rise parameter and the operating parameter. Among them, the second time threshold is greater than or equal to the first time threshold, that is, after comparing the operating parameter of the driving unit with the second parameter threshold, the operating parameter is compared with the first parameter threshold, and the connection state between the processing unit and the driving unit is gradually judged.

[0021] In some possible designs, the step of obtaining the temperature rise parameters inside the pot body specifically includes: obtaining a first temperature value inside the pot body and a second temperature value when the driving unit runs to a third time threshold; the temperature rise parameters include a temperature rise value, and the temperature rise value is equal to the difference between the second temperature value and the first temperature value; the third time threshold is greater than or equal to the second time threshold.

[0022] In this design, the step of obtaining the temperature rise parameter in the pot body specifically includes: when the running time reaches the second time threshold and the running parameter of the driving unit is judged to be greater than or equal to the second parameter threshold and less than the first parameter threshold, obtaining the first temperature value in the pot body, and then obtaining the second temperature value in the pot body when the driving unit runs to the third time threshold; when the temperature rise parameter includes the temperature rise value, calculating the difference between the second temperature value and the first temperature value and using it as the temperature rise value, comparing the difference between the second temperature value and the first temperature value with the temperature rise threshold; if the difference between the second temperature value and the first temperature value is greater than the temperature rise threshold, it means that there is no food placed in the pot; if the difference between the second temperature value and the first temperature value is less than or equal to the temperature rise threshold, it means that there is food in the pot.

[0023] In some possible designs, when the operating parameter is greater than a first parameter threshold, it is determined that the processing unit and the driving unit are in a connected state.

[0024] In this design, when the operating parameter is greater than the first parameter threshold, it means that the operating parameter of the driving unit is large, so it can be said that the processing unit is installed on the driving unit, and then it is determined that the driving unit and the processing unit are in a connected state.

[0025] The second aspect of the present invention proposes a cooking appliance, comprising: a pot body; a processing unit, at least a portion of which extends into the pot body; a driving unit, which is used to drive the processing unit to move; and a control unit, which is used to respond to target cooking instructions, obtain operating parameters of the driving unit and temperature rise parameters in the pot body, and determine the connection status of the processing unit and the driving unit based on the operating parameters and the temperature rise parameters.

[0026] The cooking device proposed in the present application includes a pot body, a processing unit, a driving unit and a control unit. At least a part of the processing unit extends into the pot body. When the processing unit is connected to the driving unit, the driving unit drives the processing unit to move, so as to process the food in the pot body. The control unit is used to respond to the target cooking instruction, obtain the temperature value in the pot body and the operating parameters of the driving unit, and determine whether the processing unit and the driving unit are in a connected state or a disconnected state according to the operating parameters and the temperature rise parameters. The operating parameters of the driving unit can reflect the connection status of the driving unit and the processing unit, and the temperature rise parameters in the pot body can reflect whether food is placed in the pot body. When food is placed in the pot body and when food is not placed in the pot body, the operating parameters of the driving unit are different. In addition, when the driving unit is not connected to the processing unit and when the driving unit is connected to the processing unit but food is not placed in the pot body, the operating parameters of the driving unit are slightly different, and it is easy to misjudge the connection status of the driving unit and the processing unit. Therefore, the technical solution proposed in the present application determines whether the processing unit is installed on the driving unit through the operating parameters of the driving unit and the temperature rise parameters in the pot body, thereby ensuring the accuracy of the detection.

[0027] In some possible designs, the processing portion includes a stirring paddle; and / or the cooking appliance further includes a heating portion, and the heating portion is used to heat the pot.

[0028] In this design, the processing part includes a stirring paddle, which, when connected to the driving part, can stir the food in the pot, increase the consistency of the food and / or speed up the cooking of the food. The heating part is used to heat the pot to cook the food.

[0029] The third aspect of the present application also proposes a control device for a cooking appliance, which is used in the control method of the cooking appliance proposed in any of the above technical solutions. The control device includes: a response unit for responding to target cooking instructions; an acquisition unit for acquiring operating parameters of the driving unit and temperature rise parameters in the pot body; and a determination unit for determining the connection status of the processing unit and the driving unit according to the operating parameters and the temperature rise parameters.

[0030] In this design, the control device of the cooking appliance includes: a response unit for responding to the target cooking instruction, an acquisition unit for acquiring the temperature rise parameter in the pot body and the operating parameter of the driving unit, and a determination unit for jointly determining whether the processing unit and the driving unit are connected according to the temperature rise parameter in the pot body and the operating parameter of the driving unit, thereby improving the accuracy of the detection of the installation status and fault conditions of the processing unit. Among them, the operating parameter of the driving unit can reflect the connection status of the driving unit and the processing unit, and the temperature rise parameter in the pot body can reflect whether food is placed in the pot body. When food is placed in the pot body and when food is not placed in the pot body, the operating parameter of the driving unit is different. In addition, when the driving unit is not connected to the processing unit and when the driving unit is connected to the processing unit but food is not placed in the pot body, the operating parameter of the driving unit is slightly different, which is easy to misjudge the connection status of the driving unit and the processing unit. Therefore, the technical solution proposed in this application determines whether the processing unit is installed on the driving unit through the operating parameter of the driving unit and the temperature rise parameter in the pot body, thereby ensuring the accuracy of the detection.

[0031] The fourth aspect of the present application also proposes an electronic device, comprising: a processor and a memory, wherein the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the cooking appliance control method as proposed in any one of the first aspects are implemented. Therefore, all the beneficial effects of the cooking appliance control method are achieved, which will not be repeated here.

[0032] The fifth aspect of the present application further proposes a readable storage medium on which a program or instruction is stored, and when the program or instruction is executed by a processor, the control method of the cooking appliance as proposed in any one of the first aspects is executed. Therefore, all the beneficial effects of the control method of the cooking appliance are achieved, which will not be repeated here.

[0033] The sixth aspect of the present application further proposes a cooking appliance, comprising: the control device of the cooking appliance as in the third aspect; and / or the electronic device as in the fourth aspect; and / or the readable storage medium as in the fifth aspect. Therefore, all the beneficial effects of the control device of the cooking appliance and / or the electronic device and / or the readable storage medium are achieved, which will not be described in detail here.

[0047] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0048] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0049] Refer to the following Figures 1 to 9 A control method for a cooking appliance, a cooking appliance, a device, and a readable storage medium according to some embodiments of the present invention are described.

[0050] According to one embodiment of the present invention, a control method for a cooking appliance is provided, which is used for the cooking appliance. The cooking appliance includes a pot body, a processing part and a driving part, at least a part of the processing part extends into the pot body, and the driving part is used to drive the processing part to move.

[0051] like Figure 1 As shown, a flow chart of a method for controlling a cooking appliance is shown:

[0052] Step 102: Responding to the target cooking instruction, obtaining the operating parameters of the driving unit and the temperature rise parameters in the pot body;

[0053] Step 104: Determine the connection status between the processing unit and the driving unit according to the operating parameters and the temperature rise parameters.

[0054] The control method of a cooking appliance provided by the present invention is used for a cooking appliance, wherein the cooking appliance comprises a pot body, a processing unit at least partly arranged in the pot body, and a driving unit for driving the processing unit to move. When the processing unit is installed on the driving unit, the movement of the processing unit can be achieved by driving the driving unit, thereby achieving the processing of food in the pot body. The control method of the cooking appliance comprises: responding to a target cooking instruction, obtaining a temperature rise parameter in the pot body and an operating parameter of the driving unit, and jointly determining whether the processing unit and the driving unit are connected according to the temperature rise parameter in the pot body and the operating parameter of the driving unit, thereby improving the accuracy of detecting the installation status and fault condition of the processing unit. Among them, the operating parameters of the driving unit can reflect the connection status of the driving unit and the processing unit, and the temperature rise parameters in the pot body can reflect whether food is placed in the pot body. The operating parameters of the driving unit are different when food is placed in the pot body and when food is not placed in the pot body. In addition, when the driving unit is not connected to the processing unit and when the driving unit is connected to the processing unit but no food is placed in the pot body, the operating parameters of the driving unit are very different, and it is easy to misjudge the connection status of the driving unit and the processing unit. Therefore, the embodiment proposed in the present application determines whether the processing unit is installed on the driving unit through the operating parameters of the driving unit and the temperature rise parameters in the pot body, thereby ensuring the accuracy of the detection.

[0055] Further, the operating parameters include the voltage value and / or current value of the driving unit. The temperature rise parameter in the pot body includes the temperature rise value of the food in the pot body within a period of time or the temperature rise rate of the food in the pot body within a period of time.

[0056] According to the embodiments proposed in the present application, it is possible to accurately determine whether the processing unit is connected to the driving unit, thereby avoiding the cooking effect being affected by the processing unit not being placed or the processing unit being separated from the driving unit during the cooking process.

[0057] It is understandable that cooking instructions include cooking programs that require the use of the processing unit and cooking programs that do not require the use of the processing unit. Among them, the target cooking instruction includes a cooking program that requires the use of the processing unit (the program is pre-set, and a specific function requires stirring). The user selects the function that needs to be cooked and enters the cooking working state. It is determined whether the current function selected by the user requires the processing unit to work, that is, it is determined whether the cooking instruction is the target cooking instruction. If the processing unit needs to be used, the target cooking instruction is responded to, the control method of the present application is entered, and the operating parameters of the driving unit are detected in real time. If the processing unit is not required in the cooking program, the detection can be ended.

[0058] like Figure 2 As shown, a flow chart of a method for controlling a cooking appliance is shown:

[0059] Step 202: Responding to the target cooking instruction, obtaining the operating parameters of the driving unit and the temperature rise parameters in the pot body;

[0060] Step 204: When the operating parameter is less than or equal to the first parameter threshold and greater than the second parameter threshold, based on the temperature rise parameter being less than or equal to the temperature rise threshold, it is determined that the processing unit and the driving unit are in a disconnected state, and a first prompt message is issued.

[0061] In this embodiment, the step of determining whether the driving unit and the processing unit are installed according to the temperature rise parameter and the operating parameter specifically includes: when the operating parameter of the driving unit is less than or equal to the first parameter threshold and greater than the second parameter threshold, if the temperature rise parameter is less than or equal to the temperature rise threshold, it means that the temperature rise speed in the pot body is slow, which further reflects that food is placed in the pot body. In this case, if the processing unit is installed on the driving unit, the processing of food by the processing unit will be hindered, so the operating parameter will increase. If the operating parameter of the driving unit is less than or equal to the first parameter threshold and greater than the second parameter threshold, it means that the load is not connected to the driving unit, that is, the processing unit is not connected to the driving unit, and then a first prompt message is issued to remind the user that the processing unit is not installed on the driving unit, so that the user can install it as soon as possible to avoid affecting the cooking effect.

[0062] It is understandable that the first prompt message is used to prompt the user that the processing unit is not connected to the driving unit. Further, the slow temperature rise rate in the pot body indicates that the heat is transferred to the food, and the food absorbs the heat, resulting in a slow temperature rise rate in the pot body.

[0063] Specifically, the first prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0064] In a specific application, the temperature rise threshold is a temperature rise value, which is greater than or equal to 1° C. and less than or equal to 20° C. The first parameter threshold can be set according to actual conditions. Specifically, the first parameter threshold includes a current value. Further, the first parameter threshold is less than or equal to 15 mA and greater than or equal to 5 mA.

[0065] like Figure 3 As shown, a flow chart of a method for controlling a cooking appliance is shown:

[0066] Step 302: Responding to the target cooking instruction, obtaining the operating parameters of the driving unit and the temperature rise parameters in the pot body;

[0067] Step 304: when the operating parameter is less than or equal to the first parameter threshold and greater than the second parameter threshold, determine whether the temperature rise parameter is less than or equal to the temperature rise threshold, if so, proceed to step 306, if not, proceed to step 308;

[0068] Step 306: determining that the processing unit and the driving unit are in a disconnected state, and issuing a first prompt message;

[0069] Step 308: Determine that no food is placed in the pot, and issue a second prompt message.

[0070] In this embodiment, when the operating parameter is less than or equal to the first parameter threshold and greater than the second parameter threshold, it is determined whether the temperature rise parameter is less than or equal to the temperature rise threshold. When the temperature rise parameter is greater than the temperature rise threshold, it means that the temperature rise in the pot is faster, and further indicates that no food is placed in the pot. In this case, a second prompt message is issued to remind the user that there is no food in the pot, so as to facilitate the user to re-place the food and avoid danger.

[0071] It is understandable that when the temperature rises quickly inside the pot, it means that there is no food in the pot to absorb heat, that is, there is no food placed in the pot, and then the temperature sensor inside the pot can sense the rapid temperature rise inside the pot.

[0072] In a specific application, the second prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0073] According to some embodiments of the present application, before the step of obtaining the temperature rise parameter in the pot body, the method further includes: obtaining the operating time of the driving unit. When the operating time is greater than or equal to the first time threshold, based on the operating parameter being less than the second parameter threshold, it is determined that the driving unit is faulty and a third prompt message is issued.

[0074] In this embodiment, before obtaining the temperature rise parameter in the pot body, it also includes: obtaining the operating time of the driving unit. When the operating time of the driving unit reaches the first time threshold, the magnitude of the operating parameter of the driving unit and the second parameter threshold is determined. If the operating parameter of the driving unit is less than the second parameter threshold, it means that the operating parameter of the driving unit is too small, that is, the driving unit is not working or is damaged, so it is determined that the driving unit has a fault, and a third prompt message is sent to the user, so that the user knows the fault of the driving unit for easy maintenance.

[0075] It can be understood that the second parameter threshold is an operating parameter when the driving unit works normally. If the operating parameter of the driving unit is less than the second parameter threshold, it indicates that the driving unit is faulty.

[0076] In a specific application, the second parameter threshold is less than the first parameter threshold. The first duration threshold and the second parameter threshold can be set according to actual conditions. Further, the first duration threshold is less than or equal to 0.5 seconds, and the second parameter threshold includes a current value, specifically, the second parameter threshold is less than or equal to 5 mA.

[0077] Specifically, the first duration threshold is equal to any value among 0.1 seconds, 0.2 seconds, 0.3 seconds, 0.4 seconds, and 0.5 seconds. The second parameter threshold is equal to any value among 1 mA, 2 mA, 3 mA, 4 mA, and 5 mA.

[0078] The third prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0079] In the embodiment proposed in the present application, after the drive unit is turned on, a self-check is performed to first determine the working status of the drive unit. If the drive unit is not in a normal working state (that is, the drive unit fails), the user is reminded to repair the drive unit.

[0080] According to some embodiments of the present application, further, the cooking appliance control method further includes: when the operating parameter is greater than or equal to the second parameter threshold: based on the operating time being greater than or equal to the second time threshold, judging the magnitude of the operating parameter and the first parameter threshold. When the operating parameter is greater than or equal to the second parameter threshold and less than or equal to the first parameter threshold, entering the step of obtaining the temperature rise parameter in the pot body; the second time threshold is greater than or equal to the first time threshold.

[0081] In this embodiment, the control method of the cooking appliance further includes: if the operating parameter of the driving unit is greater than or equal to the second parameter threshold, then determining whether the operating time of the driving unit has reached the second time threshold. If the operating time of the driving unit has reached the second time threshold, then preliminarily determining the connection state between the processing unit and the driving unit based on the magnitude of the operating parameter of the driving unit and the first parameter threshold. Specifically, within the second time threshold, if the operating parameter of the driving unit is greater than or equal to the second parameter threshold and less than the first parameter threshold, then preliminarily determining that the processing unit and the driving unit are not connected, and then controlling the cooking appliance to obtain the temperature rise parameter in the pot body, and further determining whether the processing unit is connected to the driving unit based on the temperature rise parameter and the operating parameter.

[0082] It should be noted that, when the operating parameters of the driving unit are greater than or equal to the second parameter threshold, the driving unit is judged to be operating normally, and then a preliminary judgment is made as to whether the processing unit is installed on the driving unit based on the operating parameters of the driving unit within the second time threshold. Specifically, when the operating parameters of the driving unit are greater than or equal to the second parameter threshold and less than the first parameter threshold, it means that the driving unit is operating normally, but the operating parameters are still small. In this case, the influence of the food in the pot body should be taken into account, and then the connection between the processing unit and the driving unit is further judged based on the temperature rise parameters in the pot body and the operating parameters of the driving unit, so as to ensure the reliability of the detection of the connection status between the processing unit and the driving unit.

[0083] The second duration threshold may be set according to actual conditions. Furthermore, the second duration threshold is greater than the first duration threshold.

[0084] In a specific application, the second duration threshold is greater than or equal to the first duration threshold and less than or equal to 10 seconds.

[0085] According to some embodiments of the present application, further, the step of obtaining the temperature rise parameters inside the pot body specifically includes: obtaining a first temperature value inside the pot body and a second temperature value when the driving unit runs to a third time threshold; the temperature rise parameters include a temperature rise value, and the temperature rise value is equal to the difference between the second temperature value and the first temperature value; the third time threshold is greater than or equal to the second time threshold.

[0086] In this embodiment, the step of obtaining the temperature rise parameter in the pot body specifically includes: when the running time reaches the second time threshold and the running parameter of the driving unit is judged to be greater than or equal to the second parameter threshold and less than the first parameter threshold, obtaining the first temperature value in the pot body, and then obtaining the second temperature value in the pot body when the driving unit runs to the third time threshold; when the temperature rise parameter includes the temperature rise value, calculating the difference between the second temperature value and the first temperature value and using it as the temperature rise value, comparing the difference between the second temperature value and the first temperature value with the temperature rise threshold; if the difference between the second temperature value and the first temperature value is greater than the temperature rise threshold, it means that there is no food placed in the pot; if the difference between the second temperature value and the first temperature value is less than or equal to the temperature rise threshold, it means that there is food in the pot.

[0087] In a specific application, the moment corresponding to when the operating duration of the driving unit is the second duration threshold is moment t2, and the moment corresponding to when the operating duration of the driving unit is the third duration threshold is moment t3. The first temperature value is obtained at moment t2, and the second temperature value is obtained at moment t3.

[0088] The third duration threshold is set according to actual conditions, and further, the third duration threshold is less than or equal to 10 minutes. Specifically, the third duration threshold is equal to any value of 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, and 9 minutes.

[0089] In another design, the temperature rise parameter includes the temperature rise rate. Specifically, the difference between the second temperature value and the first temperature value is the temperature difference value, the difference between the third time threshold value and the second time threshold value is the time difference, and the temperature rise rate is equal to the quotient of the temperature difference value and the time difference.

[0090] According to some embodiments of the present application, further, when the operating parameter is greater than a first parameter threshold, it is determined that the processing unit and the driving unit are in a connected state.

[0091] In this embodiment, when the operating parameter is greater than the first parameter threshold, it indicates that the operating parameter of the driving unit is large, so it can be indicated that the processing unit is installed on the driving unit, and further it is determined that the driving unit and the processing unit are in a connected state.

[0092] Further, after determining that the driving unit and the processing unit are in a connected state, the detection may be terminated.

[0093] like Figure 4As shown, the second aspect of the present invention provides a cooking appliance 400, comprising: a pot body 402; a processing unit 404, a driving unit 406, and a control unit. At least a portion of the processing unit 404 extends into the pot body 402; the driving unit 406 is used to drive the processing unit 404 to move; the control unit is used to respond to the target cooking instruction, obtain the operating parameters of the driving unit 406 and the temperature rise parameters in the pot body 402, and determine the connection state between the processing unit 404 and the driving unit 406 according to the operating parameters and the temperature rise parameters.

[0094] The cooking device 400 proposed in the present application includes a pot body 402, a processing unit 404, a driving unit 406 and a control unit. At least a portion of the processing unit 404 extends into the pot body 402. When the processing unit 404 is connected to the driving unit 406, the driving unit 406 drives the processing unit 404 to move, so as to process the food in the pot body 402. The control unit is used to respond to the target cooking instruction, obtain the temperature value in the pot body 402 and the operating parameters of the driving unit 406, and determine whether the processing unit 404 and the driving unit 406 are in a connected state or a disconnected state according to the operating parameters and the temperature rise parameters. The operating parameters of the driving unit 406 can reflect the connection status between the driving unit 406 and the processing unit 404, and the temperature rise parameters in the pot body 402 can reflect whether food is placed in the pot body 402. The operating parameters of the driving unit 406 are different when food is placed in the pot body 402 and when food is not placed in the pot body 402. In addition, the operating parameters of the driving unit 406 are slightly different when the driving unit 406 is not connected to the processing unit 404 and when the driving unit 406 is connected to the processing unit 404 but no food is placed in the pot body 402, which makes it easy to misjudge the connection status between the driving unit 406 and the processing unit 404. Therefore, the embodiment proposed in the present application determines whether the processing unit 404 is installed on the driving unit 406 through the operating parameters of the driving unit 406 and the temperature rise parameters in the pot body 402, thereby ensuring the accuracy of the detection.

[0095] According to some embodiments of the present application, further, the processing unit 404 includes a stirring paddle; and / or the cooking appliance 400 also includes a heating unit, and the heating unit is used to heat the pot body 402.

[0096] In this embodiment, the processing unit 404 includes a stirring paddle, which, when connected to the driving unit 406, can stir the ingredients in the pot 402, increase the consistency of the ingredients and / or speed up the cooking of the ingredients. The heating unit is used to heat the pot 402 to cook the ingredients.

[0097] Specifically, the driving unit 406 includes a motor.

[0098] like Figure 5As shown, the third aspect of the present application further proposes a cooking appliance control device 500, which is used in the cooking appliance control method proposed in any of the above embodiments. The cooking appliance control device 500 includes: a response unit, which is used to respond to target cooking instructions; an acquisition unit 502, which is used to acquire the operating parameters of the driving unit 406 and the temperature rise parameters in the pot body 402; and a determination unit 504, which determines the connection status between the processing unit 404 and the driving unit 406 according to the operating parameters and the temperature rise parameters.

[0099] In this embodiment, the control device 500 of the cooking appliance includes: a response unit for responding to target cooking instructions, an acquisition unit 502 for acquiring temperature rise parameters in the pot body 402 and operating parameters of the driving unit 406, and a determination unit 504 for jointly determining whether the processing unit 404 and the driving unit 406 are connected based on the temperature rise parameters in the pot body 402 and the operating parameters of the driving unit 406, thereby improving the accuracy of detection of the installation status and fault conditions of the processing unit 404. Among them, the operating parameters of the driving unit 406 can reflect the connection status of the driving unit 406 and the processing unit 404, and the temperature rise parameters in the pot body 402 can reflect whether food is placed in the pot body 402. The operating parameters of the driving unit 406 are different when food is placed in the pot body 402 and when food is not placed in the pot body 402. In addition, when the driving unit 406 is not connected to the processing unit 404 and when the driving unit 406 is connected to the processing unit 404 but no food is placed in the pot body 402, the operating parameters of the driving unit 406 are slightly different, and it is easy to misjudge the connection status of the driving unit 406 and the processing unit 404. Therefore, the embodiment proposed in the present application determines whether the processing unit 404 is installed on the driving unit 406 through the operating parameters of the driving unit 406 and the temperature rise parameters in the pot body 402, thereby ensuring the accuracy of the detection.

[0100] Further, the operating parameters include the voltage value and / or current value of the driving unit 406. The temperature rise parameter in the pot body 402 includes the temperature rise value of the food in the pot body 402 within a period of time or the temperature rise rate of the food in the pot body 402 within a period of time.

[0101] According to the embodiments proposed in the present application, it is possible to accurately determine whether the processing unit 404 is connected to the driving unit 406, thereby avoiding the cooking effect being affected by the processing unit 404 not being placed or the processing unit 404 being separated from the driving unit 406 during the cooking process.

[0102] It can be understood that the cooking instructions include cooking programs that require the use of the processing unit 404 and cooking programs that do not require the use of the processing unit 404. Among them, the target cooking instruction includes a cooking program that requires the use of the processing unit 404 (the program is pre-set, and a specific function requires stirring). The user selects the function that needs to be cooked and enters the cooking working state. It is determined whether the current function selected by the user requires the processing unit 404 to work, that is, it is determined whether the cooking instruction is the target cooking instruction. If the processing unit 404 is required, the target cooking instruction is responded to, the control method of the present application is entered, and the operating parameters of the driving unit 406 are detected in real time. If the processing unit 404 is not required in the cooking program, the detection can be ended.

[0103] According to one embodiment of the present application, the step of determining that the processing unit 404 and the driving unit 406 are connected according to the operating parameters and the temperature rise parameters is specifically used for: when the operating parameters are less than or equal to the first parameter threshold and greater than the second parameter threshold, based on the temperature rise parameter being less than or equal to the temperature rise threshold, determining that the processing unit 404 and the driving unit 406 are in a disconnected state, and issuing a first prompt message.

[0104] In this embodiment, in the step of determining whether the driving unit 406 and the processing unit 404 are installed according to the temperature rise parameter and the operating parameter, the determination unit 504 is specifically used to: when the temperature rise parameter is less than or equal to the temperature rise threshold, it means that the temperature rise speed in the pot body 402 is slow, which further reflects that food is placed in the pot body 402. In this case, if the processing unit 404 is installed on the driving unit 406, the processing of food by the processing unit 404 will be hindered, so the operating parameter will increase. If the operating parameter of the driving unit 406 is less than or equal to the first parameter threshold and greater than the second parameter threshold, it means that the load is not connected to the driving unit 406, that is, the processing unit 404 is not connected to the driving unit 406, and then a first prompt message is issued to remind the user that the processing unit 404 is not installed on the driving unit 406, so that the user can install it as soon as possible to avoid affecting the cooking effect.

[0105] It is understandable that the first prompt message is used to prompt the user that the processing unit 404 is not connected to the driving unit 406. Further, the slow temperature rise in the pot body 402 indicates that the heat is transferred to the food, and the food absorbs the heat, resulting in a slow temperature rise in the pot body 402.

[0106] Specifically, the first prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0107] In a specific application, the temperature rise threshold is a temperature rise value, which is greater than or equal to 1° C. and less than or equal to 20° C. The first parameter threshold can be set according to actual conditions. Specifically, the first parameter threshold includes a current value. Further, the first parameter threshold is less than or equal to 15 mA and greater than or equal to 5 mA.

[0108] According to some embodiments of the present application, further, a prompt unit is included, and the determination unit 504 is also used to determine that no food is placed in the pot body 402 when the temperature rise parameter is greater than the temperature rise threshold, and the prompt unit issues a second prompt message.

[0109] In this embodiment, when the temperature rise parameter is greater than the temperature rise threshold, it means that the temperature rise in the pot body 402 is relatively fast, which further indicates that no food is placed in the pot body 402. In this case, the prompt unit sends a second prompt message to remind the user that there is no food in the pot body 402, thereby facilitating the user to re-place the food and avoid danger.

[0110] It is understandable that when the temperature rises faster in the pot body 402 , it means that there is no food in the pot body 402 to absorb heat, that is, there is no food placed in the pot body 402 , and then the temperature sensor in the pot body 402 can sense the rapid temperature rise in the pot body 402 .

[0111] In a specific application, the second prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0112] According to some embodiments of the present application, further, before the step of obtaining the temperature rise parameters in the pot body 402, the acquisition unit 502 is also used to: obtain the operating time of the driving unit 406; the determination unit 504 is also used to: when the operating time is greater than or equal to the first time threshold, based on the operating parameter being less than the second parameter threshold, determine that the driving unit 406 is faulty and issue a third prompt message.

[0113] In this embodiment, before obtaining the temperature rise parameters in the pot body 402, the acquisition unit 502 also includes: obtaining the operating time of the driving unit 406, and when the operating time of the driving unit 406 reaches a first time threshold, the determination unit 504 judges the size of the operating parameters of the driving unit 406 and the second parameter threshold. If the operating parameters of the driving unit 406 are less than the second parameter threshold, it means that the operating parameters of the driving unit 406 are too small, that is, the driving unit 406 is not working or is damaged. Therefore, it is determined that the driving unit 406 has a fault, and a third prompt message is sent to the user to let the user know that the driving unit 406 has a fault for easy maintenance.

[0114] It can be understood that the second parameter threshold is an operating parameter when the driving unit 406 works normally. If the operating parameter of the driving unit 406 is less than the second parameter threshold, it means that the driving unit 406 is faulty.

[0115] In a specific application, the second parameter threshold is less than the first parameter threshold. The first duration threshold and the second parameter threshold can be set according to actual conditions. Further, the first duration threshold is less than or equal to 0.5 seconds, and the second parameter threshold includes a current value, specifically, the second parameter threshold is less than or equal to 5 mA.

[0116] Specifically, the first duration threshold is equal to any value among 0.1 seconds, 0.2 seconds, 0.3 seconds, 0.4 seconds, and 0.5 seconds. The second parameter threshold is equal to any value among 1 mA, 2 mA, 3 mA, 4 mA, and 5 mA.

[0117] The third prompt information includes a sound prompt and / or a light prompt and / or a prompt in the form of an electrical signal.

[0118] In the embodiment proposed in the present application, after the drive unit 406 is turned on, a self-check is performed to first determine the working status of the drive unit 406. If the drive unit 406 is not in a normal working state (that is, the drive unit 406 fails), the user is reminded to repair the drive unit 406.

[0119] According to some embodiments of the present application, further, the determination unit 504 is also used to: when the operating parameter is greater than or equal to the second parameter threshold, based on the operating duration being greater than or equal to the second duration threshold, judge the size of the operating parameter and the first parameter threshold; the second duration threshold is greater than or equal to the first duration threshold.

[0120] In this embodiment, if the operating parameter of the driving unit 406 is greater than or equal to the second parameter threshold, it is determined whether the operating time of the driving unit 406 reaches the second time threshold. If the operating time of the driving unit 406 reaches the second time threshold, the connection state between the processing unit 404 and the driving unit 406 is preliminarily determined based on the magnitude of the operating parameter of the driving unit 406 and the first parameter threshold. Specifically, within the second time threshold, if the operating parameter of the driving unit 406 is greater than or equal to the second parameter threshold and less than the first parameter threshold, it is preliminarily determined that the processing unit 404 and the driving unit 406 are not connected, and then the cooking appliance 400 is controlled to obtain the temperature rise parameter in the pot body 402, and whether the processing unit 404 is connected to the driving unit 406 is further determined based on the temperature rise parameter and the operating parameter.

[0121] It should be noted that, when the operating parameter of the driving unit 406 is greater than or equal to the second parameter threshold, it is determined that the driving unit 406 is operating normally, and then a preliminary judgment is made as to whether the processing unit 404 is installed on the driving unit 406 based on the operating parameter of the driving unit 406 within the second time threshold. Specifically, when the operating parameter of the driving unit 406 is greater than or equal to the second parameter threshold and less than the first parameter threshold, it is indicated that the driving unit 406 is operating normally, but the operating parameter is still small. In this case, the influence of the food in the pot body 402 should be taken into account, and then the connection between the processing unit 404 and the driving unit 406 is further judged based on the temperature rise parameter in the pot body 402 and the operating parameter of the driving unit 406, so as to ensure the reliability of the detection of the connection state between the processing unit 404 and the driving unit 406.

[0122] The second duration threshold may be set according to actual conditions. Furthermore, the second duration threshold is greater than the first duration threshold.

[0123] In a specific application, the second duration threshold is greater than or equal to the first duration threshold and less than or equal to 10 seconds.

[0124] According to some embodiments of the present application, further, the step of the acquisition unit 502 acquiring the temperature rise parameters in the pot body 402 specifically includes: acquiring a first temperature value in the pot body 402 and a second temperature value when the driving unit 406 runs to a third time threshold; the temperature rise parameters include a temperature rise value, and the temperature rise value is equal to the difference between the second temperature value and the first temperature value; the third time threshold is greater than or equal to the second time threshold.

[0125] In this embodiment, the step of the acquisition unit 502 acquiring the temperature rise parameter in the pot body 402 specifically includes: when the running time reaches the second time threshold and it is judged that the running parameter of the driving part 406 is greater than or equal to the second parameter threshold, and less than the first parameter threshold, acquiring the first temperature value in the pot body 402, and then acquiring the second temperature value in the pot body 402 when the driving part 406 runs to the third time threshold; when the temperature rise parameter includes the temperature rise value, calculating the difference between the second temperature value and the first temperature value and using it as the temperature rise value, comparing the difference between the second temperature value and the first temperature value with the temperature rise threshold; if the difference between the second temperature value and the first temperature value is greater than the temperature rise threshold, it means that no food is placed in the pot body 402; if the difference between the second temperature value and the first temperature value is less than or equal to the temperature rise threshold, it means that there is food in the pot body 402.

[0126] In a specific application, the time corresponding to when the operating duration of the driving unit 406 is the second time threshold is time t2, and the time corresponding to when the operating duration of the driving unit 406 is the third time threshold is time t3. The first temperature value is obtained at time t2, and the second temperature value is obtained at time t3.

[0127] The third duration threshold is set according to actual conditions, and further, the third duration threshold is less than or equal to 10 minutes. Specifically, the third duration threshold is equal to any value of 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes, and 9 minutes.

[0128] In another design, the temperature rise parameter includes the temperature rise rate. Specifically, the difference between the second temperature value and the first temperature value is the temperature difference value, the difference between the third time threshold value and the second time threshold value is the time difference, and the temperature rise rate is equal to the quotient of the temperature difference value and the time difference.

[0129] According to some embodiments of the present application, further, the determination unit 504 is also used to: when the operating parameter is greater than the first parameter threshold, determine that the processing unit 404 and the driving unit 406 are in a connected state.

[0130] In this embodiment, when the operating parameter is greater than the first parameter threshold, it indicates that the operating parameter of the driving unit 406 is large, so it can be indicated that the processing unit 404 is installed on the driving unit 406, and then it is determined that the driving unit 406 and the processing unit 404 are in a connected state.

[0131] Further, after determining that the driving unit 406 and the processing unit 404 are in a connected state, the detection may be terminated.

[0132] like Figure 6 As shown, the fourth aspect of the present application further proposes an electronic device 600, comprising: a processor 602 and a memory 604, wherein the memory 604 stores a program or instruction that can be run on the processor 602, and when the program or instruction is executed by the processor 602, the steps of the control method of the cooking appliance proposed in any one of the first aspects are implemented. Therefore, all the beneficial effects of the control method of the cooking appliance are achieved, which will not be repeated here.

[0133] The fifth aspect of the present application further proposes a readable storage medium on which a program or instruction is stored, wherein when the program or instruction is executed by a processor, the control method of the cooking appliance as proposed in any one of the first aspects is executed. Therefore, all the beneficial effects of the control method of the cooking appliance are achieved, which will not be described in detail here.

[0134] The sixth aspect of the present application further proposes a cooking appliance, comprising: the control device 500 of the cooking appliance as in the third aspect; and / or the electronic device 600 as in the fourth aspect; and / or the readable storage medium as in the fifth aspect. Therefore, all the beneficial effects of the control device 500 of the cooking appliance and / or the electronic device 600 and / or the readable storage medium are provided, and no further description is given here.

[0135] In specific applications, such as Figure 4As shown, in the cooking appliance 400, some function menus require the use of a stirring paddle (i.e., the processing unit 404) to stir the food in the pot during the cooking process to improve the cooking effect; during the stirring process, when the motor drives the stirring paddle to rotate, the current value generated by the motor (i.e., the driving unit 406) load will increase; when the user forgets to put the stirring paddle, the motor is equivalent to idling, and the current value generated is less; the change in the motor current value within a certain period of time can determine whether the user has placed the stirring paddle. However, since the current value when the motor rotates when not connected to the stirring paddle and the current value when the motor is connected to the stirring paddle but there is no food in the pot and the stirring paddle is idling are slightly different, in order to further identify whether the current is low due to the absence of a stirring paddle, or whether the stirring paddle has been placed but is idling due to no food in the pot, the cooking appliance 400 enters the second stage of identification and judgment. Specifically, the second stage of identification and judgment is as follows: heating the pot body 402 with a certain power to determine the rate of increase of the temperature in the pot; thereby determining whether food is placed in the pot body 402; if food is placed in the pot body 402, and the current value when the motor is rotating is still small, it can be confirmed that the motor is not placed with a stirring paddle, and the product gives a corresponding prompt.

[0136] Specifically, Figure 7 As shown, a flow chart of a method for controlling a cooking appliance is shown:

[0137] Step 702: determine whether the current function requires stirring control, if so, proceed to step 704, if not, end the detection process;

[0138] Step 704: Control the motor to enter a self-test mode, and the motor rotates from time t1 to t3;

[0139] Step 706: Enter the current sampling detection module to detect the value of the current AC;

[0140] Step 708: Determine whether the self-test time is greater than or equal to t1, if so, proceed to step 710, if not, return to step 706;

[0141] Step 710: Determine whether the detected current value AC is less than or equal to AC1, if yes, proceed to step 712, if no, proceed to step 714;

[0142] Step 712: Prompt the user that the motor is faulty;

[0143] Step 714: determine whether the self-test time is greater than or equal to t2, if so, proceed to step 716, if not, return to the step of determining whether the self-test time is greater than or equal to t2;

[0144] Step 716: Determine whether the detected current value AC is greater than AC1 and less than or equal to AC2. If so, proceed to step 718. If not, terminate the detection process.

[0145] Step 718: determining whether a stirring paddle is placed;

[0146] Step 720: Record the current temperature value T0 in the pot at time t2;

[0147] Step 722: Starting from time t2, heating starts at power W1;

[0148] Step 724: When heating reaches time t3, record the current temperature T1 in the pot;

[0149] Step 726: Determine whether (T1-T0)≤ΔT, if so, proceed to step 730, if not, proceed to step 728;

[0150] Step 728: The temperature rises too quickly and there is no food in the pot, prompting the user to place food;

[0151] Step 730: The temperature rises slowly, and it is determined that the user has placed food in the pot;

[0152] Step 732: When there are ingredients in the pot, the current value of the motor stirring is still less than or equal to AC2, confirming that the user has not placed a stirring paddle;

[0153] Step 734: Prompt the user that the stirring paddle is not placed.

[0154] In this embodiment, the user selects the function to be cooked and enters the cooking working state. It is judged whether the currently selected function of the user requires stirring processing (the program has a preset setting, and specific functions require stirring processing); if the current function does not require stirring processing, the detection processing is ended; if the current function requires stirring processing, the motor self-check is entered; the motor has been rotating from time t1 to t3; the motor current value AC is collected in real time; if the self-check time (i.e., the running duration) is less than t1, continue to collect AC; if the self-check time is greater than or equal to t1, judge whether the AC value is less than the preset current value AC1 (AC1 is the current value generated when the motor rotates normally); if AC is less than AC1, it is considered that the motor has not rotated or is damaged, and the user is reminded that there is a motor fault; if AC is greater than or equal to AC1, judge whether the time is greater than or equal to t2. If the self-check time is less than t2, continue the detection; when the self-check time is greater than or equal to t2, judge whether AC is greater than AC2. If so, it means that the user has placed the stirring paddle, and when the motor rotates, it is stirring the ingredients in the pot body, so the current value during rotation is large, and the detection processing is ended; if AC1 < AC ≤ AC2, it means that the motor is rotating normally, but the current value generated by the rotation is small; it is impossible to judge whether the stirring paddle is placed on the motor (the current value when the motor rotates without placing the stirring paddle is similar to the current value when the stirring paddle is placed on the motor but there are no ingredients in the pot body and the motor is idling). To further confirm which state it belongs to currently, further judgment is required: at time t2, record the current temperature T0 in the pot body, heat the product at power W1 until time t3, and record the temperature T1 in the pot body at time t3; judge the rising trend of the temperature in the pot body from time t2 to t3; if the temperature rises slowly (T1–T0) ≤ ΔT, it means that there are ingredients placed in the pot body, and the heat is transferred to the ingredients, so the temperature rises slowly; because the motor has been rotating, if the stirring paddle is placed at this time, the stirring paddle will be hindered when stirring the ingredients, and the current value will increase; if the current value of the motor is still AC1 < AC ≤ AC2 at this time, it is confirmed that the stirring paddle is not placed at this time, and the user is prompted to place the stirring paddle; if the temperature rises quickly (T1–T0) > ΔT from time t2 to t3, it means that there are no ingredients placed in the pot, the motor is idling, and the current value of the motor is still AC1 < AC ≤ AC2, and the user is prompted to place the ingredients. By detecting the current value of the motor within a certain period of time, it is judged whether the user has placed the stirring paddle. When the current value is small and it is initially judged that the stirring paddle is not placed, it will enter the second judgment. By judging the rising trend of the temperature in the pot body and combining the current value of the motor for secondary judgment, it is finally confirmed whether the stirring paddle is placed.

[0155] Among them, AC1 current value range: less than or equal to 5 mA; AC2 current value range: greater than AC1, less than or equal to 15 mA; t1 time value range: less than or equal to 0.5 seconds; t2 time value range: greater than t1, less than or equal to 10 seconds; t3 time value range: greater than t2, less than or equal to 10 minutes; W1 power range: 1 / 4 rated power to full power; the shorter the time (t3-t2), the larger the value of power W1 selected; ΔT temperature difference in the pot: 1℃ to 20℃; the shorter the time (t3-t2), the smaller ΔT.

[0156] According to some embodiments of the present application, it is first determined whether AC is greater than AC2. If AC is greater than AC2, it indicates that there is a stirring paddle. If AC is less than AC2, it is detected whether AC is less than AC1. If AC is less than AC1, it indicates that the motor is faulty. If AC is greater than AC1, temperature determination is performed. Specifically, during the temperature determination process, the current temperature value T0 in the pot is recorded at time t2; starting from time t2, heating is started with power W1; when heating reaches time t3, the current temperature T1 in the pot is recorded; it is determined whether (T1-T0)≤ΔT. If so, the temperature rises slowly, and it is determined that the user has placed food in the pot. If there is food, the motor current value AC is still less than AC1, indicating that the stirring paddle is not placed; if (T1-T0)>ΔT, the temperature rises too fast, indicating that there is no food in the pot, and the user is prompted to place food.
