[0022] The following details the implementation manners of the present application. Examples of the implementation manners are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation manners described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0023] In order to enable those skilled in the art of the present technology to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0024] With the development of science and technology, people's living standards are getting higher and higher, and cooking utensils are becoming more and more diverse. At present, most cooking utensils generate hot air through heating tubes, and then make the hot air circulate rapidly in a sealed space through a hot air convection system to achieve heating of food. Among them, in order to promote the flow of hot air in the cooking utensil, a blower is provided in most cooking utensils. In the related art, in order to facilitate the cleaning of the cooking utensil, the fan blades of the blower are exposed on the lid of the cooking utensil, so that the user can thoroughly clean the cooking utensil, ensuring the hygiene of the cooked food. Exemplarily, for the convenience of cleaning, the IH air fryer cancels the safety cover of the blower. However, for cooking utensils with fan blades exposed on the lid, there is a problem that when the user opens the lid, the rotating fan blades may hurt the user's hand. For example, the blower of the IH air fryer has a long diameter and a large weight, so the inertia is large, and it is difficult for the blower of the IH air fryer to stop rotating after the power is cut off. Therefore, cooking utensils face challenges in meeting safety regulations requirements.

[0025] In view of the above problems, through long-term research, the inventors have found and proposed an open-lid control method, device and cooking utensil provided by an embodiment of the present application. The electronic switch is used to control the unlocking or locking of the lid button, and the locking duration of the open-lid button controlled by the electronic switch is determined according to the working parameters during the working process of the cooking utensil, so as to ensure that the fan blades stop rotating when the user opens the lid, improve the safety of using the cooking utensil, and improve the user experience. Among them, the specific control method will be described in detail in the subsequent embodiments.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic diagram of the cooking utensil in the lid-closed state provided by an embodiment of the present application, Figure 2 which shows a schematic diagram of the cooking utensil in the lid-open state provided by an embodiment of the present application. In the embodiment of the present application, the cooking utensil 100 has an air fry function. Among them, air frying refers to a method of generating hot air through a heating tube, and then making the hot air circulate rapidly in a sealed space through a hot air convection system to achieve heating of food. In the embodiment of the present application, the cooking utensil 100 can be an air fryer.

[0027] According to Figure 2 it can be seen that the cooking utensil 100 includes a housing 103, a frying bucket 101, a cooking cavity 102, and a lid 104. Among them, the frying bucket 101 can be disassembled to facilitate taking out when ingredients need to be placed or taken out. The frying bucket 101 has a receiving space, and the receiving space forms at least a part of the cooking cavity 102, and the upper part of the receiving space is open.

[0028] The cooking appliance 100 may further include a fan 140 (not shown), which is used to provide a circulating airflow in the cooking cavity 102 so that the hot air circulates to all areas in the cooking cavity 102 to improve the uniformity of heating. For example, the fan 140 is a fan of model DC220V, 50Hz, 25W. In this embodiment, the fan 140 can be arranged in the top area of ​​the frying bucket 101, and the fan blades of the fan 140 are exposed and arranged on the pot cover 104, and are used to provide a circulating airflow toward the cooking cavity 102. In this way, when the fan 140 is working, the heat generated by the heating device can be circulated to various places of the cooking cavity 102 in the frying bucket 101 by generating a circulating airflow, so that the heat is evenly dispersed in various places in the cooking cavity 102. Among them, the fan 140 can have multiple working gears, such as high gear (rotation speed above 2500rpm / min), medium gear (1500-2500rpm / min), low gear (rotation speed below 1500rpm / min), etc. Among them, under different working gears, the fan 140 can provide different wind speeds and different air volumes. According to different usage requirements, different working gears of the fan 140 can be selected to adjust the wind speed, air volume, etc. In this embodiment, the number of the fan 140 is 1. In some other implementations, the number of the fan 140 can be multiple, which is not limited in this embodiment.

[0029] Please refer to Figure 3 , which shows a perspective view of a cooking utensil provided by an embodiment of the present application. The pot cover 104 is provided with a cover opening button 11 and an electronic switch 12, wherein the electronic switch 12 can be provided at the cover opening button 11, for locking the cover opening button 11 so that the cover cannot be opened, or for unlocking the cover opening button 11 so that the cover can be opened. The electronic switch 12 can include an electronic switch such as a solenoid valve, a relay, etc., which is not limited here.

[0030] The cooking device 100 further includes a heating device, which can be disposed on the housing 103 and used to heat different areas of the cooking cavity 102. The heating device can include one or more heating elements, such as a heating tube, a heating coil, a heating belt, etc., which are not limited here. For example, a heating tube with a DC voltage of DC220V, 50Hz, and 1000W.

[0031] The cooking appliance 100 may further include a temperature detection device and an electronic control device 160 (not shown). The temperature detection device is used to detect the temperature in the cooking cavity 102. There may be one or more temperature detection devices, and the temperature detection device may be various types of temperature sensors, such as a thermistor NTC temperature sensor, a thermocouple temperature sensor, etc. This embodiment does not limit this.

[0032] When the cooking appliance 100 further includes an electric control device 160 (not shown in the figure), the electric control device 160 is electrically connected to the heating device, the temperature detection device, the electronic switch 12, and the blower 140, and is used to control the operation of the heating device, the temperature detection device, the electronic switch 12, and the blower 140. Specifically, it controls the start or stop of the heating device, the temperature detection device, and the blower 140, as well as the operating parameters during startup, and controls the electronic switch 12 to lock the lid opening button 11 and operating parameters such as the locking time of the lid opening button 11.

[0033] In some embodiments, the electric control device 160 can also be connected to the control panel on the housing 103. When the control panel receives an operation signal for any one of the function controls, it generates a corresponding electrical signal and sends it to the electric control device 160. The electric control device 160 controls the cooking appliance 100 based on this electrical signal. In the embodiments of the present application, the electric control device 160 starts to execute the current cooking process after receiving a cooking instruction. Optionally, the electric control device 160 is a MicroController Unit (MCU).

[0034] In some embodiments, the electric control device 160 can execute the current control process after receiving a control instruction. The current control process can include, when the lid 104 is in the closed state, controlling the lid opening button 11 to be locked through the electronic switch 12; obtaining the operating parameters of the cooking appliance 100 during the working process, and determining the waiting duration according to the operating parameters, where the operating parameters include being always powered on or not always being powered on; after the waiting duration, controlling the lid opening button 11 to be unlocked through the electronic switch 12, where the fan blade of the blower 140 stops rotating during the waiting duration, and then controlling the lid opening button 11 to be unlocked or locked through the electronic switch 12, and determining the duration for which the electronic switch 12 controls the lid opening button 11 to be locked according to the operating parameters of the cooking appliance 100 during the working process, so as to ensure that the fan blade stops rotating when the user opens the lid, improve the safety of using the cooking appliance 100, and improve the user experience.

[0035] Please refer to Figure 4 , Figure 4 which shows a schematic flow chart of the lid opening control method of the cooking appliance provided by an embodiment of the present application. The lid opening control method of the cooking appliance controls the lid button to be unlocked or locked through an electronic switch, and determines the duration for which the electronic switch controls the lid button to be locked according to the operating parameters of the cooking appliance during the working process, so as to ensure that the fan blade stops rotating when the user opens the lid, improve the safety of using the cooking appliance, and improve the user experience. In a specific embodiment, the control method can be applied to a control device 200 as shown in Figure 10 and a cooking appliance 100 configured with the control device 200 ( Figure 11)。Taking a cooking appliance as an example below, the specific process of this embodiment will be described. Of course, it can be understood that the cooking appliance to which this embodiment is applied may include an air fryer, an oven, a microwave oven, etc., which are not limited herein. The following will be directed to Figure 4 The shown process will be elaborated in detail. The control method may specifically include the following steps:

[0036] Step S110: When the pot lid is in the closed state, control the unlocking of the opening button through the electronic switch.

[0037] In this embodiment, the cooking appliance may include devices such as a pressure sensor and a light sensor. The cooking appliance can determine whether the cooking appliance is in the closed state by obtaining the pressure signal detected by the pressure sensor; the cooking appliance can also determine whether the cooking appliance is in the closed state by obtaining the light signal detected by the light sensor.

[0038] Exemplarily, considering that when the pot lid of the cooking appliance is opened, light will enter the cooking cavity. Correspondingly, compared with the state where the pot lid of the cooking appliance is closed, the light signal in the cooking cavity is stronger. In this embodiment, if the cooking appliance detects that the intensity of the light signal in the cooking cavity is greater than the light intensity threshold through the light sensor, it can be determined that the pot lid is in the open state.

[0039] In some embodiments, when the pot lid is in the closed state, the cooking appliance can control the unlocking of the opening button through the electronic switch. Among them, when the pot lid is in the closed state, the cooking appliance can start working. Correspondingly, an open-top cooking appliance cannot start working in the open state to ensure the safety of using the cooking appliance.

[0040] Among them, in order to ensure the smooth progress of the cooking work of the cooking appliance, in this embodiment, the cooking appliance can control the unlocking of the opening button through the electronic switch when the pot lid is in the closed state, avoid the accidental opening of the pot lid of the cooking appliance during the working process, and ensure that the fan blades stop rotating when opening the lid again.

[0041] Step S120: Obtain the working parameters of the cooking appliance during the working process, and determine the waiting duration according to the working parameters, where the working parameters include being always powered on or not always being powered on.

[0042] In this embodiment, to ensure that the fan blade of the cooking appliance has stopped rotating when the cooking appliance is opened, the operating parameters of the cooking appliance during the working process can be obtained, and the waiting duration can be determined according to the operating parameters. Among them, the waiting duration can include the duration for which the electronic switch locks the opening button, can also include the duration for which the cooking appliance locks the opening button in response to an opening request through the electronic switch, can further include the duration for which the cooking appliance locks the opening button after cooking is completed, and can also include the duration for which the cooking appliance locks the opening button when power is restored after power-off.

[0043] Among them, the working process of the cooking appliance can include a heating and cooking process, a heat preservation process, a cleaning process, etc., which are not limited herein. Among them, the operating parameters of the cooking appliance during the working process can include whether the cooking appliance has been in an energized state all the time or not, and can also include the rotational speed of the fan in the cooking appliance during the working process.

[0044] In some embodiments, the cooking appliance can obtain the operating parameters of the cooking appliance during the working process after the normal end of the work, or when a work stop instruction is detected, or when power is restored after a power interruption during the working process, etc.

[0045] In this embodiment, after the cooking appliance obtains the operating parameters, the waiting duration can be determined according to the operating parameters. Exemplarily, the cooking appliance can obtain the operating parameters after the normal end of the work. If the operating parameters include being in an energized state all the time, the waiting duration can be determined to be a first preset duration; the cooking appliance can obtain the operating parameters after detecting a work stop instruction. If the operating parameters include being in an energized state all the time, the waiting duration can be determined to be a second preset duration. Among them, the first preset duration and the second preset duration can be the same or different, which are not limited herein.

[0046] Among them, the first preset duration and the second preset duration can be pre-set in the cooking appliance, or can be obtained by the cooking appliance from an associated electronic device in a wireless or wired manner; among them, the first preset duration and the second preset duration can be obtained through third-party experimental data, or can be set independently by the user, which are not limited herein. Exemplarily, the first preset duration and the second preset duration are the same and are obtained according to the diameter or weight of the fan blade. For example, it is 10 seconds to 35 seconds. Among them, considering that the longer the diameter of the fan blade and the heavier the weight, the greater the rotational inertia. In this embodiment, the waiting duration corresponding to the fan blade with a longer diameter and a greater weight can be set longer to ensure that the fan blade stops rotating within the waiting duration.

[0047] Optionally, the first preset duration and the second preset duration can also be determined according to the rotational speed of the blower fan. For example, obtain the rotational speed of the blower fan when the cooking appliance normally ends its operation, or obtain the rotational speed of the blower fan when the cooking appliance detects a work stop instruction, or obtain the rotational speed of the blower fan of the cooking appliance at the moment of power-off, and determine the waiting duration according to the rotational speed of the blower fan. Among them, the waiting duration corresponding to the blower fan with a greater rotational speed can be set longer to ensure that the blower fan stops rotating within this waiting duration.

[0048] Step S130: After the waiting duration, control the unlocking of the lid-opening button through the electronic switch, where the blower fan stops rotating within the waiting duration.

[0049] In some embodiments, after determining the waiting duration, the cooking appliance can, after this waiting duration, control the unlocking of the lid-opening button through the electronic switch. Wherein, the blower fan stops rotating within this waiting duration.

[0050] Optionally, the cooking appliance can, after normal operation ends or when a work stop instruction is detected, after the waiting duration, control the unlocking of the lid-opening button through the electronic switch.

[0051] Exemplarily, please refer to Figure 5 , which shows a schematic flowchart of the lid-opening control method of the cooking appliance provided by an embodiment of the present application. Among them, the electronic switch included in the cooking appliance is a solenoid valve. When the cooking appliance is in the lid-closed state, the cooking appliance can start working. This solenoid valve can lock the lid-opening button to ensure that the cooking appliance cannot be opened, so that the cooking appliance can work smoothly. Among them, after the cooking appliance finishes working, the cooking appliance can obtain that the working parameter of the cooking appliance has been in the powered-on state all the time, and obtain the waiting duration as T seconds according to this working parameter. Correspondingly, after the cooking appliance finishes working, continue to lock the lid-opening button by this solenoid valve for T seconds, and release the locking of the lid-opening button by this solenoid valve after T seconds. It can be understood that when the solenoid valve releases the locking of the lid-opening button, that is, unlocks, the lid of the cooking appliance can be opened. Among them, the blower fan has stopped rotating within this waiting duration, avoiding the user's hand being scratched by the blower fan when opening the lid, and improving the safety of using the cooking appliance.

[0052] Optionally, the cooking appliance can, after starting to work and then powering off and powering on again midway, after the waiting duration, control the unlocking of the lid-opening button through the electronic switch.

[0053] Exemplarily, please refer to Figure 6, which shows a schematic flowchart of the open - lid control method of a cooking appliance provided by an embodiment of the present application. Among them, the electronic switch included in the cooking appliance is a solenoid valve. When the cooking appliance is in the closed - lid state, the cooking appliance can start working, and this solenoid valve can lock the open - lid button to ensure that the cooking appliance cannot be opened, so that the cooking appliance can work smoothly. Among them, if the cooking appliance loses power during the working process, such as being unplugged or having a power outage, the cooking appliance can continue to lock the open - lid button through the solenoid valve to ensure that the pot lid cannot be opened, so as to avoid the pot lid being opened and affecting the cooking performance. Correspondingly, after the cooking appliance is re - powered, if the cooking appliance obtains that the working parameter of the cooking appliance is not in the continuously - powered - on state, the waiting duration can be determined according to this working parameter. Among them, the cooking appliance can determine whether the control unit of the cooking appliance has a power - off memory function; if it has a power - off memory function, the cooking appliance can obtain the duration of power - off of the cooking appliance and determine the waiting duration according to the result of comparing this duration with a third preset duration. Among them, after the cooking appliance is re - powered and reaches this waiting duration, it can control the solenoid valve to release the lock on the open - lid button, so as to ensure that when the user opens the pot lid, the fan stops rotating, improve the safety of using the cooking appliance, and facilitate the user to flexibly open the lid of the cooking appliance after the cooking appliance is powered on, improving the user experience.

[0054] The control method provided by an embodiment of the present application, when the pot lid is in the closed - lid state, controls the open - lid button to be locked through an electronic switch to ensure the smooth progress of the working process of the cooking appliance; by obtaining the working parameters of the cooking appliance during the working process and determining the waiting duration according to the working parameters, where the working parameters include being in the continuously - powered - on state or not being in the continuously - powered - on state, so as to determine the waiting duration for the electronic switch to control the unlocking of the open - lid button according to the two situations of the cooking appliance being in the continuously - powered - on state and not being in the continuously - powered - on state. Among them, the fan stops rotating during this waiting duration, and after the waiting duration, the open - lid button is unlocked by controlling the electronic switch, so as to ensure that the fan stops rotating after the cooking appliance is opened, avoid the user being scratched by the exposed fan blades, improve the safety of using the cooking appliance, and also improve the user experience.

[0055] Please refer to Figure 7 , Figure 7 , which shows a schematic flowchart of the open - lid control method of a cooking appliance provided by an embodiment of the present application. This method is applied to the above - mentioned cooking appliance. The following will elaborate in detail on the Figure 7 shown flowchart. The control method can specifically include the following steps:

[0056] Step S210: When the pot lid is in the closed - lid state, control the open - lid button to be locked through the electronic switch.

[0057] Among them, for the specific description of step S210, please refer to the specific description of step S110 above, and it will not be elaborated here.

[0058] Step S220: Obtain the working parameters of the cooking appliance during operation. If it is determined based on the working parameters that the cooking appliance has been in the powered-on state, determine the first time length as the waiting duration, where the first time length is determined according to the diameter and / or weight of the blower fan.

[0059] In some embodiments, after the cooking appliance starts working with the lid closed, it can receive a work stop instruction input by the user. For example, the work stop instruction input by the user manually clicking the stop or end button of the cooking appliance; the cooking appliance can also end the normal work. Based on this, the cooking appliance can obtain the working parameters of the cooking appliance during operation; among them, if the cooking appliance has been in the powered-on state during operation, the cooking appliance can determine the first time length as the waiting duration. Wherein, the first time length is determined according to the diameter and / or weight of the blower fan.

[0060] In this embodiment, considering that the inertia of the blower fan rotation is related to the diameter length and weight of the blower fan itself, to ensure that the blower fan has stopped rotating within the waiting duration, the first time length can be determined according to the diameter and / or weight of the blower fan. For example, the longer the diameter of the blower fan, the longer the waiting duration, and the greater the weight of the blower fan, the longer the waiting duration.

[0061] Exemplarily, please refer to again Figure 5 , which shows a schematic flow chart of the lid-opening control method of the cooking appliance provided in an embodiment of the present application. Among them, the electronic switch included in the cooking appliance is a solenoid valve. When the cooking appliance is in the state of the lid closed, the cooking appliance can start working, and the solenoid valve can lock the lid-opening button to ensure that the cooking appliance cannot open the lid for the cooking appliance to work smoothly. Among them, during the operation of the cooking appliance, the cooking appliance can receive a work stop instruction input by the user. Based on this, the cooking appliance can obtain that the working parameter of the cooking appliance has been in the powered-on state and obtain the waiting duration as the first time length T seconds according to the working parameter. Correspondingly, the cooking appliance can release the locking of the lid-opening button by the solenoid valve T seconds after receiving the work stop instruction. Among them, if the cooking appliance does not receive a work stop instruction during operation, the cooking appliance can also control the solenoid valve to continue to lock the lid-opening button for T seconds after the work is completed and release the locking of the lid-opening button by the solenoid valve after T seconds. It can be understood that when the locking of the lid-opening button by the solenoid valve is released, the lid of the cooking appliance can be opened so that the user can flexibly control the operation of the cooking appliance and improve the user experience. Among them, the blower fan has stopped rotating within the waiting duration, avoiding the user's hand being scratched by the blower fan when opening the lid and improving the safety of using the cooking appliance.

[0062] Step S230: After the waiting duration, control the unlocking of the lid-opening button through the electronic switch, wherein the wind blade stops rotating during the waiting duration.

[0063] For the specific description of step S230, please refer to the specific description of step S130 above, and details will not be repeated here.

[0064] The control method provided by an embodiment of the present application, compared with Figure 4 the shown control method, this embodiment can also obtain the working parameters of the cooking appliance during the working process. If it is determined based on the working parameters that the cooking appliance has been in an energized state all the time, the first time length is determined as the waiting duration, where the first time length is determined according to the diameter and / or weight of the wind blade. Furthermore, when the cooking appliance has not been powered off, the waiting duration is determined according to the diameter and / or weight of the wind blade, and after this waiting duration, the lid-opening button is controlled to be unlocked through the electronic switch, ensuring that the wind blade has stopped rotating when the lid is opened, improving the safety of using the cooking appliance and also improving the user experience.

[0065] Please refer to Figure 8 , Figure 8 which shows a schematic flowchart of the lid-opening control method of the cooking appliance provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance. Next, the Figure 8 shown process will be elaborated in detail. The control method may specifically include the following steps:

[0066] Step S310: When the lid of the pot is in the closed state, control the locking of the lid-opening button through the electronic switch.

[0067] For the specific description of step S310, please refer to the specific description of step S110 above, and details will not be repeated here.

[0068] Step S320: Obtain the working parameters of the cooking appliance during the working process. If it is determined based on the working parameters that the cooking appliance has not been in an energized state all the time, then determine whether the cooking appliance has a memory function.

[0069] In some embodiments, if the cooking appliance has not been in an energized state all the time, when the cooking appliance is powered off and then powered on again, the cooking appliance can obtain the working parameters of the cooking appliance during the working process. If it is determined based on the working parameters that the cooking appliance has not been in an energized state all the time, then it can be further determined whether the cooking appliance has a memory function. Among them, the memory function can time the duration of the power-off of the cooking appliance.

[0070] As an implementable way, the process of determining whether a cooking appliance has a memory function may include determining whether the cooking appliance can receive an electrical signal output by a battery assembled in the cooking appliance when the cooking appliance is not connected to the mains power. If it can receive the signal, it is determined that the cooking appliance has the memory function; otherwise, it does not have the memory function.

[0071] Step S330: If it is determined that the cooking appliance has the memory function, obtain the duration for which the cooking appliance is in an unpowered state, and determine the waiting duration according to the duration for which the cooking appliance is in an unpowered state.

[0072] In some embodiments, if the cooking appliance determines that the cooking appliance has the memory function, it may obtain the duration for which the cooking appliance is in an unpowered state, that is, obtain the duration for which the cooking appliance is powered off. Accordingly, the cooking appliance may determine the waiting duration according to the duration for which the cooking appliance is not in a powered state.

[0073] In some embodiments, a second time length may be preset in the cooking appliance. The second time length may be determined according to the diameter and weight of the wind blade, or may be set independently by the user without limitation. Preferably, the second time length is determined according to the diameter and weight of the wind blade to prevent the wind blade from scratching the user's hand when the lid is opened before it stops rotating. The second time length may be the same as or different from the first time length, which is not limited herein. Exemplarily, the second time length is the same as the first time length and is 10 to 35 seconds.

[0074] After the cooking appliance obtains the duration for which it is in an unpowered state, it may compare the duration with the second time length and determine the waiting duration according to the comparison result. Exemplarily, if the duration for which the cooking appliance is in an unpowered state is greater than or equal to the second time length, it may be determined that the waiting duration is zero. It can be understood that the wind blade has stopped rotating during the period when the cooking appliance is powered off. Accordingly, after the cooking appliance is powered on again, the solenoid valve can directly release the lock on the lid opening button, thereby reducing the power consumption of the cooking appliance. Or, if the duration for which the cooking appliance is in an unpowered state is less than the second time length, the difference between the second time length and the duration for which the cooking appliance is in an unpowered state may be determined as the waiting duration. It can be understood that the fan has not stopped rotating during the period when the cooking appliance is powered off. Accordingly, after the cooking appliance is powered on again, the solenoid valve can be controlled to continue locking the lid opening button for this waiting duration to improve the safety of using the cooking appliance.

[0075] Step S340: If the cooking appliance does not have the memory function, determine the third time length as the waiting duration, where the third time length is determined according to the diameter and / or weight of the wind blade.

[0076] In some embodiments, if the cooking appliance determines that it does not have a memory function, the third time length can be determined as the waiting duration. The third time length can be preset in the cooking appliance. The third time length can be determined according to the diameter and weight of the blower fan, or can be set by the user independently, which is not limited herein. Preferably, the third time length is determined according to the diameter and weight of the blower fan to prevent the blower fan from scratching the user's hand when the lid is opened before it stops rotating. The third time length can be the same as or different from the first time length and / or the second time length, which is not limited herein. Exemplarily, the third time length, the first time length, and the second time length are the same and are 10 to 35 seconds.

[0077] It can be understood that, in the case where it is determined that the cooking appliance does not have a memory function, to ensure that the blower fan stops rotating when the lid is opened, the third time length determined according to the diameter and / or weight of the blower fan can be determined as the waiting duration.

[0078] Step S350: After the duration from the non-powered state to the powered state of the cooking appliance reaches the waiting duration, control the unlocking of the lid-opening button through the electronic switch.

[0079] In some embodiments, after the cooking appliance determines the waiting duration, it can control the lid-opening button to be unlocked through the electronic switch after the duration from the non-powered state to the powered state of the cooking appliance reaches the waiting duration.

[0080] Exemplarily, please refer to again Figure 6, which shows a schematic flowchart of the open - lid control method of a cooking appliance provided by an embodiment of the present application. Among them, the electronic switch included in the cooking appliance is a solenoid valve. When the cooking appliance is in the closed - lid state, the cooking appliance can start working. This solenoid valve can lock the open - lid button to ensure that the cooking appliance cannot be opened, so that the cooking appliance can work smoothly. Among them, if the cooking appliance loses power during operation, for example, is unplugged or there is a power outage, the cooking appliance can continue to lock the open - lid button through the solenoid valve to ensure that the pot lid cannot be opened, so as to avoid the impact on cooking performance caused by the opening of the pot lid. Correspondingly, after the cooking appliance is re - powered, the cooking appliance obtains that the working parameter of the cooking appliance has not been in the powered - on state all the time, and can determine the waiting duration according to this working parameter. The cooking appliance can judge whether the control unit of the cooking appliance has the power - off memory function; if it has the power - off memory function, the cooking appliance can obtain the duration of power - off of the cooking appliance, and determine the waiting duration according to the result of comparing this duration T0 seconds with the second time length T seconds. Optionally, if it is determined that this duration is greater than or equal to the second time length, the solenoid valve can be controlled to release the lock on the open - lid button, so that the user can open the pot lid of the cooking appliance, and it is ensured that the fan stops rotating when the user opens the pot lid, improving the safety of using the cooking appliance, and facilitating the user to flexibly open the lid of the cooking appliance after the cooking appliance is powered on, improving the user experience.

[0081] Among them, if it is determined that this duration is less than the second time length, the difference between the second time length and the duration when the cooking appliance is in the non - powered - on state can be determined as the waiting duration (T - T0). After the cooking appliance is re - powered, the solenoid valve can be controlled to continue locking the open - lid button for this waiting duration, and then the solenoid valve is controlled to release the lock on the open - lid button, so that the user can open the pot lid of the cooking appliance, and it is ensured that the fan stops rotating when the user opens the pot lid, improving the safety of using the cooking appliance, and facilitating the user to flexibly open the lid of the cooking appliance after the cooking appliance is powered on, improving the user experience.

[0082] Among them, if the cooking appliance does not have the memory function, the third time length T seconds can be determined as the waiting duration. After the cooking appliance is re - powered, the solenoid valve can be controlled to continue locking the open - lid button for T seconds, and then the solenoid valve is controlled to release the lock on the open - lid button, so that the user can open the pot lid of the cooking appliance, and it is ensured that the fan stops rotating when the user opens the pot lid, improving the safety of using the cooking appliance, and facilitating the user to flexibly open the lid of the cooking appliance after the cooking appliance is powered on, improving the user experience.

[0083] The control method provided by an embodiment of the present application, compared with Figure 4For the control method shown, in this embodiment, the working parameters of the cooking appliance during operation can also be obtained. If it is determined based on the working parameters that the cooking appliance has not been continuously powered on, it is determined whether the cooking appliance has a memory function. If it is determined that the cooking appliance has a memory function, the duration of the cooking appliance being in the non-powered state is obtained, and the waiting duration is determined according to the duration of the cooking appliance being in the non-powered state. If the cooking appliance does not have a memory function, the third time length is determined as the waiting duration, where the third time length is determined according to the diameter and / or weight of the blower blade. After the duration of the cooking appliance transitioning from the non-powered state to the powered state reaches the waiting duration, the opening button is unlocked through the electronic switch. Thus, in the case where the cooking appliance has not been continuously powered on, it is determined whether the cooking appliance has a memory function, and the waiting duration is determined based on this memory function, so that after the duration of the cooking appliance transitioning from the non-powered state to the powered state reaches the waiting duration, the opening button is unlocked through the electronic switch, facilitating the user to flexibly open the cooking appliance after it is powered on, ensuring that the blower blade stops rotating when the user opens the pot lid, improving the usage safety of the cooking appliance, and enhancing the user experience.

[0084] Please refer to Figure 9 , Figure 9 which shows a schematic flowchart of the lid opening control method for a cooking appliance provided in an embodiment of the present application. This method is applied to the above-mentioned cooking appliance. The following will elaborate in detail on Figure 9 the process shown. The control method may specifically include the following steps:

[0085] Step S410: When the pot lid is in the closed state, in response to a cooking instruction, control the opening button to be locked through the electronic switch.

[0086] In some embodiments, a control panel is provided on the outer shell assembly of the cooking appliance. The control panel includes a start control. After the cooking appliance obtains an operation signal for the start control, a cooking instruction can be obtained. When the start control is a virtual control, the above operation signal can be a click operation signal, a double-click operation signal, a swipe operation signal, etc.; when the start control is a physical control, the above operation signal can be a single or multiple press operation signals.

[0087] In some embodiments, the cooking instruction can also be sent by other devices through wireless or wired communication methods. For example, the cooking appliance can be communicatively connected to the user's mobile terminal, and the user can control and send the cooking instruction on the mobile terminal.

[0088] In some other embodiments, when the appointed time arrives, the cooking appliance obtains a cooking instruction. The appointed time may be the time that the user preset in advance and expects the cooking appliance to start cooking. Optionally, the control panel of the cooking appliance further includes an appointment control. When receiving an operation signal for the appointment control and the appointment duration input by the user, when the appointed time arrives, the cooking appliance obtains a cooking instruction. The duration between the moment when the cooking appliance obtains the appointment duration and the appointed time is the above-mentioned appointment duration.

[0089] Among them, when the lid of the cooking appliance is in the closed state, in response to the cooking instruction, the cooking appliance can control the unlocking button of the lid to be locked through an electronic switch to ensure the smooth operation of the cooking appliance.

[0090] Step S420: Obtain the working parameters of the cooking appliance during the working process, and determine the waiting duration according to the working parameters, where the working parameters include being always powered on or not always being powered on.

[0094] Step S440: After the duration of receiving the work stop instruction reaches the waiting duration, control the unlocking button of the lid to be unlocked through the electronic switch.

[0095] Among them, considering that after the cooking appliance obtains the work stop instruction input by the user, the possibility that the user then opens the lid of the cooking appliance is relatively high. In this embodiment, after the cooking appliance determines the waiting duration, when the duration of receiving the work stop instruction reaches the waiting duration, it can control the unlocking button of the lid to be unlocked through the electronic switch to ensure that the fan stops rotating when the user opens the lid and improve the safety of using the cooking appliance.

[0096] The control method provided by an embodiment of the present application, compared with Figure 4For the control method shown, in this embodiment, the cooking appliance can also unlock the lid-opening button through the electronic switch after the working duration of the cooking appliance reaches the waiting duration, and unlock the lid-opening button through the electronic switch after the duration of receiving the work stop instruction reaches the waiting duration. Furthermore, when it is possible for the user to open the cooking appliance, it is ensured that the blower fan stops rotating when the user opens the lid, improving the safety of using the cooking appliance and enhancing the user experience.
