Description

Technical Field

[0001] This application relates to the field of cooking equipment technology, and more specifically, to a control method and apparatus for cooking equipment, a readable storage medium, and cooking equipment. Background Technology

[0002] In related technologies, cooking equipment such as air fryers require the cooking chamber to be tightly closed during the cooking process. If the cooking chamber is not closed tightly, such as if the top cover is not closed tightly, the heat inside the cooking chamber will dissipate outward, causing the temperature inside the cooking chamber to be substandard, and may even burn the user.

[0003] A common solution is to install a trigger sensor on the air fryer to detect whether the lid is closed properly. This can be achieved by using a matching component and a micro switch. After the lid is closed, the matching component will press the trigger switch, and the state of the trigger switch will be used to detect whether the lid is closed tightly.

[0004] When the structural components and microswitches are not well matched, or when the product has been used for a long time and the structural components have slightly deformed due to prolonged temperature effects, false triggering is likely to occur, resulting in poor detection reliability. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the first aspect of this application proposes a method for controlling a cooking device.

[0007] The second aspect of this application proposes a control device for a cooking apparatus.

[0008] The third aspect of this application proposes a control device for a cooking apparatus.

[0009] The fourth aspect of this application proposes a readable storage medium.

[0010] The fifth aspect of this application proposes a cooking device.

[0011] In view of this, the first aspect of this application provides a control method for a cooking device, the cooking device including a cooking chamber and functional components, the control method including: acquiring an electrical signal corresponding to the functional components; and determining the opening and closing state of the cooking chamber based on the electrical signal.

[0012] In this technical solution, the cooking equipment can be an air fryer, an oven, or other food processors with air frying function.

[0013] The cooking device includes a cooking chamber and functional components. Exemplarily, the cooking chamber includes a main body and a top cover; the open / closed state of the cooking chamber refers to the state in which the top cover is engaged with the main body. Exemplarily, the cooking chamber includes a main body and a drawer; the open / closed state of the cooking chamber refers to whether the drawer is detached from the main body. Exemplarily, the functional components include a fan, a temperature sensor, etc. To ensure the temperature inside the cooking chamber reaches the set target temperature while preventing hot steam from scalding the user, the cooking chamber needs to be sealed during cooking operations; therefore, the cooking chamber needs to be closed. If the cooking chamber is not closed, the user needs to be alerted, and the cooking device should be prevented from performing cooking operations.

[0014] In related technologies, to detect whether the cooking chamber is closed, a trigger-type sensor is generally required. This typically involves a matching structure and a microswitch. After the cooking chamber is closed, the matching structure continuously presses the trigger switch, thus detecting whether it is fully closed based on the state of the trigger switch. However, when the matching degree between the structure and the microswitch is not high, or when the product has been used for a long time and the structure has slightly deformed due to prolonged temperature changes, false triggering can easily occur, resulting in poor detection reliability.

[0015] To address the aforementioned issues, the technical solution of this application detects whether the cooking chamber is closed by utilizing the detection results of electrical signals from functional components.

[0016] As the cooking chamber changes its opening and closing state, the electrical signals of the functional components also change. Specifically, when the engagement state between the lid and the main body changes, or when the lid is removed from the main body, the electrical signals of the functional components will also change. For example, assuming the cooking chamber includes a main body and a lid, when the lid and the main body are engaged, the functional components are correctly connected to the electrical path of the control chip. When a path is formed between the control chip and the functional components, the presence of the functional components causes a change in the voltage at the specific interface where the control chip and the functional components are connected. Alternatively, when the functional components are connected to the control chip, the control chip drives the functional components to operate, and at this time, the functional components will have operating current.

[0017] The technical solution of this application determines the opening and closing status of the cooking chamber based on the electrical signal corresponding to the detection function component. It eliminates the need for matching structural components and microswitches, thereby improving the reliability of detecting whether the lid is closed while reducing hardware structure and thus lowering hardware costs.

[0018] In addition, the control method for the cooking equipment in the above-mentioned technical solution provided in this application may also have the following additional technical features:

[0019] In some technical solutions of this application, the cooking device also includes a control component; wherein, when the open / closed state is closed, the functional component and the control component are connected via a communication interface; when the open / closed state is open, the functional component and the communication interface are not connected; the step of obtaining the electrical signal corresponding to the functional component specifically includes: obtaining the voltage value of the communication interface through the control component.

[0020] In this technical solution, the cooking device includes a control component, which, exemplarily, is the main control board or main control chip of the cooking device. Functional components specifically include temperature sensors, pressure sensors, or other electronic devices. Taking a temperature sensor as an example, the temperature sensor is disposed within the main body and is used to detect the temperature value within the cooking chamber of the cooking device, controlling the cooking device to perform cooking operations based on the detected temperature value.

[0021] For example, the temperature sensor can be an NTC (Negative Temperature Coefficient) sensor.

[0022] For example, taking a temperature sensor as a functional component, during the cooking operation of the cooking device, the cooking chamber is in a closed state. A signal path is formed between the communication interface of the control component and the temperature sensor. The control component receives the detection signal from the temperature sensor through the communication interface and determines the real-time temperature value in the cooking chamber based on the detection signal. When the real-time temperature in the cooking chamber reaches the target temperature set by the user's cooking command, the heating power of the heating component is reduced accordingly; otherwise, the heating component is controlled to run at full power.

[0023] When the cooking chamber is closed, a communication path is formed between the temperature sensor and the control component. The temperature sensor acts as a voltage divider in this path, causing the voltage at the communication interface detected by the control chip to drop. When the lid and body are not closed, the coupling between the temperature sensor and the control component is broken. The temperature sensor no longer applies voltage, and the voltage at the communication interface rises accordingly. Therefore, the open / closed state of the cooking chamber can be determined, enabling reliable detection of the lid's open / closed status.

[0024] In some embodiments of this application, optionally, the step of determining the opening and closing state of the cooking chamber based on an electrical signal specifically includes: determining the opening and closing state as closed when the voltage value is less than a voltage value threshold; or determining the opening and closing state as open when the voltage value is greater than or equal to a voltage value threshold.

[0025] In this technical solution, the control component includes a control chip, and the control chip includes a communication interface. When the functional component and the control component are coupled together, the communication interface of the control chip is electrically connected to the functional component. At this time, the control chip can detect the cooking temperature in the cooking device through the signal value of the communication interface.

[0026] For example, taking a temperature sensor as a functional component, after the cooking device is started, the signal value of signal AD on the communication interface of the control component of the cooking device, specifically the control chip, is fixedly set to AD0. When the lid and body are fastened together and the control component is connected to the temperature sensor, due to the voltage division effect of the temperature sensor's own resistance, the signal value detected on the communication interface of the control chip will be less than AD0. At this time, it can be determined that the temperature sensor and the control component are coupled and connected, thus determining that the lid and body are in the closed state.

[0027] If the signal value detected on the communication interface of the control chip is greater than or equal to AD0, it indicates that the temperature sensor is open. At this time, it is determined that the temperature sensor is disconnected from the control component, and thus the open state of the cover and the body is determined.

[0028] The technical solution of this application detects the signal value of the communication interface between the control chip of the detection control component and the temperature sensor, and determines whether the temperature sensor is open based on the signal value, thereby realizing reliable detection of the opening and closing status of the cooking chamber.

[0029] In some technical solutions of this application, optionally, the step of obtaining the electrical signal corresponding to the functional component specifically includes: obtaining the operating current value of the fan.

[0030] In this technical solution, the functional components include a heating element, a fan, etc., and exemplarily, the heating element can be a resistance heating element or an electromagnetic heating element. Exemplarily, the electromagnetic heating element is an IH coil, which generates an electromagnetic field that forms eddy currents on the metal fan blades of the fan. The metal fan blades then heat up under the influence of the current and transfer the heat to the cooking chamber through rotation, thereby heating the food.

[0031] For example, taking a fan as a functional component, during the cooking operation of the cooking device, the cooking chamber is in a closed state. At this time, an electrical path is formed between the control component and the fan. The control component determines the working status of the fan by detecting the fan current. After the cooking device is turned on, the fan is powered on, and the control component can detect the operating current of the fan. It is understood that the operating current of the fan is positively correlated with the output power of the fan.

[0032] When the cooking chamber is in the open state, the path between the fan and the control components is disconnected. At this time, the open circuit between the fan and the control components can be detected by detecting the fan current, so as to infer the opening and closing state of the cooking chamber and realize reliable detection of the opening and closing state of the lid.

[0033] In some technical solutions of this application, optionally, the step of determining the opening and closing state of the cooking chamber based on the electrical signal specifically includes: determining the opening and closing state as closed when the absolute value of the operating current is greater than the current threshold; or determining the opening and closing state as open when the absolute value of the operating current is less than or equal to the current threshold.

[0034] In this technical solution, when a path is formed between the control component and the functional component, the control component can obtain the operating current of the functional component. When the path between the control component and the functional component is short-circuited, the operating current of the functional component is 0. Therefore, the operating state of the functional component can be determined based on the operating current.

[0035] For example, taking a fan as a functional component, after the cooking device is started, the control component of the cooking device detects the operating current of the fan in real time. When the cover and the body are fastened together, a path is formed between the control component and the fan, and the control component can obtain the operating current of the fan. It can be understood that when the fan is powered on, the operating current of the fan is not zero, and the operating current of the fan is positively correlated with the output power of the fan. Therefore, as long as the operating current of the fan is detected to be non-zero, it can be determined that a path is formed between the fan and the control component, and thus the state of the cover and the body being closed can be determined.

[0036] Conversely, if the operating current of the fan is detected to be 0, it is determined that the fan and the control components are disconnected, and the open state of the cover and the main body is determined.

[0037] Because current detection has a certain margin of error, a preset current threshold can be set. If the obtained operating current value of the fan is greater than the current threshold, the fan's operating current is determined to be non-zero, and the cover and body are confirmed to be in the closed state. If the absolute value of the obtained operating current value of the fan is less than or equal to the current threshold, the fan's operating current is determined to be zero, and the cover and body are confirmed to be in the open state.

[0038] The technical solution of this application detects the operating current value of the fan and determines the connection status between the fan and the control components based on the comparison result of the operating current value of the fan and the current threshold, thereby realizing reliable detection of the opening and closing status of the cooking chamber.

[0039] Optionally, in some technical solutions of this application, after determining the opening and closing state of the cooking chamber based on an electrical signal, the control method further includes: when the opening and closing state is closed, controlling the cooking device to perform a cooking operation based on target cooking parameters; or when the opening and closing state is open, controlling the cooking device to perform at least one of the following operations: stopping the cooking operation and outputting an opening prompt message.

[0040] In this technical solution, when the lid and body of the cooking device are closed, the cooking chamber of the cooking device is in a sealed state. At this time, the heat inside the cooking chamber will not escape, and the cooking device will perform cooking operations normally according to the cooking parameters indicated by the cooking instructions.

[0041] When the lid and body are open, the cooking chamber of the cooking device is not sealed, and heat may escape from the cooking chamber. For example, if cooking is in progress, the cooking device will stop performing the current cooking operation. If the cooking device is about to start cooking, the cooking device will not start cooking and will remind the user that the lid is not closed properly by outputting an open lid prompt message.

[0042] The technical solution of this application determines the opening and closing state of the lid by means of the coupling state between the control component and the functional component, and controls the cooking device to perform the corresponding cooking operation based on the opening and closing state of the lid, which can improve cooking safety.

[0043] Optionally, in some technical solutions of this application, the functional components include a temperature sensor.

[0044] In this technical solution, exemplarily, the functional component includes a temperature sensor, which is, exemplarily, an NTC temperature sensor. When the cooking compartment is closed, a communication path is formed between the temperature sensor and the control component. The temperature sensor exerts a voltage divider effect in this path, causing the voltage value of the communication interface detected by the control chip to be pulled down due to the voltage divider effect of the temperature sensor. When the lid and body are not fastened together, the coupling connection between the temperature sensor and the control component is broken. At this time, the temperature sensor no longer exerts a voltage divider, and the voltage value of the communication interface will correspondingly increase. Therefore, the open / closed state of the cooking compartment can be inferred, achieving reliable detection of the open / closed state of the lid.

[0045] In some technical solutions of this application, the functional component optionally includes a motor.

[0046] In this technical solution, the motor can be a fan or a drive motor that moves the components inside the cooking chamber. For example, when the motor is operating, its operating current is not zero. When the cooking chamber is closed, an electrical path is formed between the control component and the motor, and the motor's operating current is not zero. When the cooking chamber is open, the path between the motor and the control component is broken, resulting in an open circuit and zero motor operating current. Therefore, the opening / closing state of the cooking chamber can be inferred by detecting the motor current, achieving reliable detection of the lid's opening / closing state.

[0047] In some technical solutions of this application, the functional components optionally include an electromagnetic heating element and a fan, wherein the electromagnetic heating element is used to heat the fan blades.

[0048] In this technical solution, exemplarily, the cooking device is an IH (Induction Heat) air fryer, and the functional components include an electromagnetic heating element and a fan. Exemplarily, the electromagnetic heating element is an IH coil. During cooking, the IH coil heats the metal fan blades of the fan via electromagnetic heating. The metal fan blades accumulate heat under the heating effect of the IH coil. When the fan rotates, the blades transfer heat to the food inside the cooking chamber through thermal radiation, and also transfer heat to the surrounding air medium. The heated air flows into the cooking chamber under the guidance of the fan blades, thereby transferring heat to the food inside the cooking chamber. When the cooking chamber is closed, an electrical path is formed between the control components and the fan, and the fan operating current is not zero.

[0049] When the cooking chamber is in the open state, the path between the fan and the control components is disconnected. At this time, the fan and the control components are open, and the fan operating current is 0. Therefore, the opening and closing state of the cooking chamber can be inferred by detecting the fan current, thus achieving reliable detection of the opening and closing state of the lid.

[0050] The second aspect of this application provides a control device for a cooking device, the cooking device including a cooking chamber and functional components, the control device including: an acquisition module for acquiring electrical signals corresponding to the functional components; and a determination module for determining the opening and closing state of the cooking chamber based on the electrical signals.

[0051] In this technical solution, the cooking equipment can be an air fryer, an oven, or other food processors with air frying function.

[0052] The cooking device includes a cooking chamber and functional components. Exemplarily, the cooking chamber includes a main body and a top cover; the open / closed state of the cooking chamber refers to the state in which the top cover is engaged with the main body. Exemplarily, the cooking chamber includes a main body and a drawer; the open / closed state of the cooking chamber refers to whether the drawer is detached from the main body. Exemplarily, the functional components include a fan, a temperature sensor, etc. To ensure the temperature inside the cooking chamber reaches the set target temperature while preventing hot steam from scalding the user, the cooking chamber needs to be sealed during cooking operations; therefore, the cooking chamber needs to be closed. If the cooking chamber is not closed, the user needs to be alerted, and the cooking device should be prevented from performing cooking operations.

[0053] In related technologies, to detect whether the cooking chamber is closed, a trigger-type sensor is generally required. This typically involves a matching structure and a microswitch. After the cooking chamber is closed, the matching structure continuously presses the trigger switch, thus detecting whether it is fully closed based on the state of the trigger switch. However, when the matching degree between the structure and the microswitch is not high, or when the product has been used for a long time and the structure has slightly deformed due to prolonged temperature changes, false triggering can easily occur, resulting in poor detection reliability.

[0054] To address the aforementioned issues, the technical solution of this application detects whether the cooking chamber is closed by utilizing the detection results of electrical signals from functional components.

[0055] As the cooking chamber changes its opening and closing state, the electrical signals of the functional components also change. Specifically, when the engagement state between the lid and the main body changes, or when the lid is removed from the main body, the electrical signals of the functional components will also change. For example, assuming the cooking chamber includes a main body and a lid, when the lid and the main body are engaged, the functional components are correctly connected to the electrical path of the control chip. When a path is formed between the control chip and the functional components, the presence of the functional components causes a change in the voltage at the specific interface where the control chip and the functional components are connected. Alternatively, when the functional components are connected to the control chip, the control chip drives the functional components to operate, and at this time, the functional components will have operating current.

[0056] The technical solution of this application determines the opening and closing status of the cooking chamber based on the electrical signal corresponding to the detection function component. It eliminates the need for matching structural components and microswitches, thereby improving the reliability of detecting whether the lid is closed while reducing hardware structure and thus lowering hardware costs.

[0069] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0070] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0071] The following reference Figures 1 to 6 This application describes a control method and apparatus for a cooking device, a readable storage medium, and a cooking device according to some embodiments thereof.

[0072] In some embodiments of this application, a method for controlling a cooking device is provided. Figure 1 The following are schematic diagrams illustrating the structure of a cooking apparatus according to some embodiments of this application, such as... Figure 1 As shown, the cooking device 100 includes a cooking chamber 102 and a functional component 108.

[0074] Step 202: Obtain the electrical signal corresponding to the functional component;

[0075] Step 204: Determine the opening and closing status of the cooking chamber based on the electrical signal.

[0076] In this embodiment, the cooking equipment can be an air fryer, a baking oven, or other food processors with air frying function.

[0077] For example, such as Figure 1 As shown, the cooking device 100 includes a cooking chamber 102, which includes a cover 1024 and a body 1022. Exemplarily, the control component 106 includes a main control board 1062 and a coupler 1064 of the cooking device 100. The functional component 108 assists the cooking device 100 in performing cooking operations.

[0078] To ensure the cooking chamber reaches the set target temperature and prevent hot steam from scalding the user, the cooking chamber needs to be sealed during cooking. Therefore, the cooking chamber must be closed. If the cooking chamber is not closed, the user should be alerted, and the cooking device should be stopped from performing cooking operations.

[0079] In related technologies, to detect whether the cooking chamber is closed, a trigger-type sensor is generally required. This typically involves a matching structure and a microswitch. After the cooking chamber is closed, the matching structure continuously presses the trigger switch, thus detecting whether it is fully closed based on the state of the trigger switch. However, when the matching degree between the structure and the microswitch is not high, or when the product has been used for a long time and the structure has slightly deformed due to prolonged temperature changes, false triggering can easily occur, resulting in poor detection reliability.

[0080] To address the aforementioned issues, the technical solution of this application detects whether the cooking chamber is closed by utilizing the detection results of electrical signals from functional components.

[0081] As the cooking chamber changes its opening and closing state, the electrical signals of the functional components also change. Specifically, when the engagement state between the lid and the main body changes, or when the lid is removed from the main body, the electrical signals of the functional components will also change. For example, assuming the cooking chamber includes a main body and a lid, when the lid and the main body are engaged, the functional components are correctly connected to the electrical path of the control chip. When a path is formed between the control chip and the functional components, the presence of the functional components causes a change in the voltage at the specific interface where the control chip and the functional components are connected. Alternatively, when the functional components are connected to the control chip, the control chip drives the functional components to operate, and at this time, the functional components will have operating current.

[0082] The technical solution of this application determines the opening and closing status of the cooking chamber based on the electrical signal corresponding to the detection function component. It eliminates the need for matching structural components and microswitches, thereby improving the reliability of detecting whether the lid is closed while reducing hardware structure and thus lowering hardware costs.

[0083] In some embodiments of this application, the cooking device may optionally include a control component; wherein, when the open / closed state is closed, the functional component is communicatively connected to the communication interface of the control component; when the open / closed state is open, the functional component is not connected to the communication interface; the step of obtaining the electrical signal corresponding to the functional component specifically includes: obtaining the voltage value of the communication interface through the control component.

[0084] In this embodiment, the cooking device includes a control component, which, exemplarily, is the main control board or main control chip of the cooking device. Functional components specifically include temperature sensors, pressure sensors, or other electronic devices. Taking a temperature sensor as an example, the temperature sensor is disposed in the main body and is used to detect the temperature value inside the cooking chamber of the cooking device, controlling the cooking device to perform cooking operations based on the detected temperature value.

[0085] For example, the temperature sensor can be an NTC (Negative Temperature Coefficient) sensor.

[0086] For example, taking a temperature sensor as a functional component, during the cooking operation of the cooking device, the cooking chamber is in a closed state. A signal path is formed between the communication interface of the control component and the temperature sensor. The control component receives the detection signal from the temperature sensor through the communication interface and determines the real-time temperature value in the cooking chamber based on the detection signal. When the real-time temperature in the cooking chamber reaches the target temperature set by the user's cooking command, the heating power of the heating component is reduced accordingly; otherwise, the heating component is controlled to run at full power.

[0087] When the cooking chamber is closed, a communication path is formed between the temperature sensor and the control component. The temperature sensor acts as a voltage divider in this path, causing the voltage at the communication interface detected by the control chip to drop. When the lid and body are not closed, the coupling between the temperature sensor and the control component is broken. The temperature sensor no longer applies voltage, and the voltage at the communication interface rises accordingly. Therefore, the open / closed state of the cooking chamber can be determined, enabling reliable detection of the lid's open / closed status.

[0088] In some embodiments of this application, optionally, the step of determining the opening and closing state of the cooking chamber based on an electrical signal specifically includes: determining the opening and closing state as closed when the voltage value is less than a voltage value threshold; or determining the opening and closing state as open when the voltage value is greater than or equal to a voltage value threshold.

[0089] In this embodiment, the control component includes a control chip, and the control chip includes a communication interface. When the functional component and the control component are coupled together, the communication interface of the control chip is electrically connected to the functional component. At this time, the control chip can detect the cooking temperature in the cooking device through the signal value of the communication interface.

[0090] For example, taking a temperature sensor as a functional component, after the cooking device is started, the signal value of signal AD on the communication interface of the control component of the cooking device, specifically the control chip, is fixedly set to AD0. When the lid and body are fastened together and the control component is connected to the temperature sensor, due to the voltage division effect of the temperature sensor's own resistance, the signal value detected on the communication interface of the control chip will be less than AD0. At this time, it can be determined that the temperature sensor and the control component are coupled and connected, thus determining that the lid and body are in the closed state.

[0091] If the signal value detected on the communication interface of the control chip is greater than or equal to AD0, it indicates that the temperature sensor is open. At this time, it is determined that the temperature sensor is disconnected from the control component, and thus the open state of the cover and the body is determined.

[0092] The technical solution of this application detects the signal value of the communication interface between the control chip of the detection control component and the temperature sensor, and determines whether the temperature sensor is open based on the signal value, thereby realizing reliable detection of the opening and closing status of the cooking chamber.

[0093] In some embodiments of this application, optionally, the functional component includes a motor, and the step of obtaining the electrical signal corresponding to the functional component specifically includes: obtaining the operating current value of the motor.

[0094] For example, taking a motor as a functional component, during the cooking operation of the cooking device, the cooking chamber is in a closed state. At this time, an electrical path is formed between the control component and the motor. The control component determines the circuit status by detecting the motor current. After the cooking device is turned on, the motor is powered on, and the control component can detect the motor's operating current.

[0095] When the cooking chamber is in the open state, the circuit between the motor and the control components is disconnected. At this time, the open circuit between the motor and the control components can be detected by detecting the motor current to infer the opening and closing state of the cooking chamber, thus achieving reliable detection of the opening and closing state of the lid.

[0096] In some embodiments of this application, optionally, the step of determining the opening and closing state of the cooking chamber based on the electrical signal specifically includes: determining the opening and closing state as closed when the absolute value of the operating current is greater than the current threshold; or determining the opening and closing state as open when the absolute value of the operating current is less than or equal to the current threshold.

[0097] In this embodiment, when a path is formed between the control component and the functional component, the control component can obtain the operating current of the functional component. When the path between the control component and the functional component is broken, the operating current of the functional component is 0. Therefore, the operating state of the functional component can be determined based on the operating current.

[0098] For example, taking a motor as a functional component, after the cooking device is started, the control component of the cooking device detects the operating current of the motor in real time. When the cover and the body are fastened together, a path is formed between the control component and the motor, and the control component can obtain the operating current of the motor. It can be understood that when the motor is powered on, the operating current of the motor is not zero, and the operating current of the motor is positively correlated with the output power of the motor. Therefore, as long as the operating current of the motor is detected to be non-zero, it can be determined that a path is formed between the motor and the control component, and thus the state of the cover and the body being closed can be determined.

[0099] Conversely, if the operating current of the motor is detected to be 0, it is determined that the motor and the control components are disconnected, and the open state of the cover and the main body is determined.

[0100] Because current detection has a certain margin of error, a preset current threshold can be set. If the obtained motor operating current value is greater than the current threshold, the motor operating current is determined to be non-zero, and the cover and body are confirmed to be in the closed state. If the absolute value of the obtained motor operating current value is less than or equal to the current threshold, the motor operating current is determined to be zero, and the cover and body are confirmed to be in the open state.

[0101] The technical solution of this application detects the operating current value of the motor and determines the connection status between the motor and the control components based on the comparison result of the operating current value of the motor and the current threshold, thereby realizing reliable detection of the opening and closing status of the cooking chamber.

[0102] In some embodiments of this application, optionally, after determining the opening and closing state of the cooking chamber based on an electrical signal, the control method further includes: when the opening and closing state is closed, controlling the cooking device to perform a cooking operation based on target cooking parameters; or when the opening and closing state is open, controlling the cooking device to perform at least one of the following operations: stopping the cooking operation and outputting an opening prompt message.

[0103] In this embodiment, when the lid and body of the cooking device are closed, the cooking chamber of the cooking device is in a sealed state. At this time, the heat inside the cooking chamber will not escape, and the cooking device will perform the cooking operation normally according to the cooking parameters indicated by the cooking instructions.

[0104] When the lid and body are open, the cooking chamber of the cooking device is not sealed, and heat may escape from the cooking chamber. For example, if cooking is in progress, the cooking device will stop performing the current cooking operation. If the cooking device is about to start cooking, the cooking device will not start cooking and will remind the user that the lid is not closed properly by outputting an open lid prompt message.

[0105] The embodiments of this application determine the opening and closing state of the lid by means of the coupling state between the control component and the functional component, and control the cooking device to perform the corresponding cooking operation based on the opening and closing state of the lid, which can improve cooking safety.

[0106] Optionally, in some embodiments of this application, before the step of acquiring the electrical signal corresponding to the functional component, the control method further includes: determining target cooking parameters in response to a cooking command.

[0107] In this embodiment, when using the cooking equipment, users can input cooking commands through human-computer interaction interfaces such as knobs, buttons, and touchscreens, or through voice control, or remotely through mobile applications. The cooking commands specify target cooking parameters, including cooking power, cooking time, and cooking mode.

[0108] Upon receiving a cooking instruction, the cooking device determines the corresponding target cooking parameters and obtains the open / closed state of the lid. When the lid is closed, the cooking device starts the cooking operation based on the target cooking parameters. When the lid is open, the cooking device outputs a corresponding prompt message reminding the user to close the lid.

[0109] The embodiments of this application can reliably detect the opening and closing state of the top cover. After receiving a cooking command, it determines whether to perform the cooking operation based on the opening and closing state of the top cover, thereby improving the reliability of the cooking equipment.

[0110] In some embodiments of this application, optionally, such as Figure 1 As shown, functional component 108 includes temperature sensor 1084.

[0111] In this embodiment, the functional component includes, exemplarily, a temperature sensor, specifically an NTC temperature sensor. When the cooking compartment is closed, a communication path is formed between the temperature sensor and the control component. The temperature sensor exerts a voltage divider effect within this path, causing the voltage at the control chip's communication interface to drop due to this voltage divider. When the lid and body are not closed, the coupling between the temperature sensor and the control component is broken. The temperature sensor no longer applies a voltage divider, and the voltage at the communication interface rises accordingly. Therefore, the opening / closing state of the cooking compartment can be inferred, enabling reliable detection of the lid's opening / closing status.

[0112] In some embodiments of this application, the functional component optionally includes a motor.

[0113] In this embodiment, the motor can be a fan or a drive motor that moves the components inside the cooking chamber. For example, when the motor is operating, its operating current is not zero. When the cooking chamber is closed, an electrical path is formed between the control component and the motor, and the motor's operating current is not zero. When the cooking chamber is open, the path between the motor and the control component is broken, resulting in an open circuit and zero motor operating current. Therefore, the opening / closing state of the cooking chamber can be inferred by detecting the motor current, achieving reliable detection of the lid's opening / closing state.

[0114] In some embodiments of this application, optionally, such as Figure 1 As shown, the cooking device includes an electromagnetic heating element 1086 and a fan 1082, wherein the electromagnetic heating element 1086 is used to heat the fan blades of the fan 1082.

[0115] For example, the cooking device is an IH (Induction Heat) air fryer, which includes an electromagnetic heating element and a fan. For example, the electromagnetic heating element is an IH coil. During cooking, the metal blades of the fan heat up under the action of the IH coil. When the fan rotates, the blades transfer heat to the food inside the cooking chamber through thermal radiation, and also to the surrounding air medium. The heated air flows into the cooking chamber under the guidance of the blades, thereby transferring heat to the food inside. Because the blades both heat up and rotate, if the circuit status is not detected in time when the lid is open and a circuit breaker is not performed in time, it may cause burns, mechanical injuries, or other harm to the user. The solution used in this application, which determines the opening and closing status of the cooking chamber based on electrical signals, is more stable, reliable, and has a faster response speed than the microswitch solution in the prior art, and can largely avoid the occurrence of risks.

[0116] In some embodiments of this application, Figure 3 A flowchart illustrating a control method for a cooking apparatus according to some embodiments of this application is shown, such as... Figure 3 As shown, the method includes:

[0117] Step 302, start cooking;

[0118] Step 304: The control chip detects the signal value AD from the temperature sensor;

[0119] Step 306: Determine if AD < AD0; if yes, proceed to step 310; otherwise, proceed to step 308.

[0120] Step 308: Determine if the lid is open and display a prompt message;

[0121] Step 310, normal operation.

[0122] The control chip internally has a fixed AD value of AD0. When the control chip is properly connected to the NTC, the NTC's own resistance can divide the voltage, so the AD value detected by the chip port will be less than AD0. In this case, the chip will not detect a lid opening fault when the machine starts up. When the control chip is not connected to the NTC, the NTC is open, and the AD value detected by the chip port will be greater than or equal to AD0. In this case, the chip will detect a lid opening fault when the machine starts up.

[0123] Figure 4 A flowchart illustrating a control method for a cooking apparatus according to some embodiments of this application is shown, such as... Figure 4 As shown, the method includes:

[0124] Step 402, start cooking;

[0125] Step 404: The control chip detects the motor current value;

[0126] Step 406: Determine if the current value is 0; if yes, proceed to step 408; otherwise, proceed to step 410.

[0127] Step 408: Determine if the lid is open and display a prompt message;

[0128] Step 410, normal operation.

[0129] If the cover and motor are not connected when the machine starts up, the chip will detect a cover-opening fault as the motor current will be 0, causing the machine to stop working and display a fault message. When the motor is properly connected and the machine is started, the current flowing through the motor will not be 0, and the chip will not detect a cover-opening fault; the machine can then continue operating.

[0130] In some embodiments of this application, a control device for a cooking apparatus is provided, the cooking apparatus including a cooking chamber and functional components. Figure 5 Structural block diagrams of the control device of a cooking apparatus according to some embodiments of this application are shown, such as... Figure 5As shown, the control device 500 includes: an acquisition module 502 for acquiring electrical signals corresponding to functional components; and a determination module 504 for determining the opening and closing state of the cooking chamber based on the electrical signals.

[0131] In this embodiment, the cooking equipment can be an air fryer, a baking oven, or other food processors with air frying function.

[0132] The cooking device includes a cooking chamber and functional components. Exemplarily, the cooking chamber includes a main body and a top cover; the open / closed state of the cooking chamber refers to the state in which the top cover is engaged with the main body. Exemplarily, the cooking chamber includes a main body and a drawer; the open / closed state of the cooking chamber refers to whether the drawer is detached from the main body. Exemplarily, the functional components include a motor, a temperature sensor, etc. To ensure the temperature inside the cooking chamber reaches the set target temperature while preventing hot steam from scalding the user, the cooking chamber needs to be sealed during cooking operations; therefore, the cooking chamber needs to be closed. If the cooking chamber is not closed, the user needs to be alerted, and the cooking device should be prevented from performing cooking operations.

[0133] In related technologies, to detect whether the cooking chamber is closed, a trigger-type sensor is generally required. This typically involves a matching structure and a microswitch. After the cooking chamber is closed, the matching structure continuously presses the trigger switch, thus detecting whether it is fully closed based on the state of the trigger switch. However, when the matching degree between the structure and the microswitch is not high, or when the product has been used for a long time and the structure has slightly deformed due to prolonged temperature changes, false triggering can easily occur, resulting in poor detection reliability.

[0134] To address the aforementioned issues, the technical solution of this application detects whether the cooking chamber is closed by utilizing the detection results of electrical signals from functional components.

[0135] As the cooking chamber changes its opening and closing state, the electrical signals of the functional components also change. Specifically, when the engagement state between the lid and the main body changes, or when the lid is removed from the main body, the electrical signals of the functional components will also change. For example, assuming the cooking chamber includes a main body and a lid, when the lid and the main body are engaged, the functional components are correctly connected to the electrical path of the control chip. When a path is formed between the control chip and the functional components, the presence of the functional components causes a change in the voltage at the specific interface where the control chip and the functional components are connected. Alternatively, when the functional components are connected to the control chip, the control chip drives the functional components to operate, and at this time, the functional components will have operating current.

[0136] The technical solution of this application determines the opening and closing status of the cooking chamber based on the electrical signal corresponding to the detection function component. It eliminates the need for matching structural components and microswitches, thereby improving the reliability of detecting whether the lid is closed while reducing hardware structure and thus lowering hardware costs.
