[0002] With the advancement of smart home appliance technology, a cooking appliance that automatically stirs food using a stirring device has emerged. This automatic stirring function enables the preparation of various dishes such as stir-frying, braising, stewing, and steaming, allowing for unattended cooking and bringing great convenience to users.

[0003] However, in actual cooking, the stirring device is prone to getting stuck in various scenarios such as cooking large quantities of ingredients, cooking viscous ingredients, or burning ingredients, which can lead to damage to the cooking appliance. Summary of the Invention

[0006] Check whether the stirring device is stuck;

[0007] If the stirring device is stuck, adjust the state of the stirring blades and control the stirring device to rotate at a preset angle. Control the stirring blades to return to the state before adjustment and control the stirring device to rotate. Then, check again whether the stirring device is stuck.

[0023] Check whether the stirring blades are installed correctly. If the stirring blades are installed correctly, check whether the stirring device is stuck.

[0024] In one feasible implementation, the method further includes:

[0025] If the stirring blade is installed incorrectly, a second prompt message is output to remind the user to install it correctly, or cooking is stopped. This avoids inaccurate subsequent test results due to improper installation of the stirring blade by the user.

[0026] In one feasible implementation, after the number of times the stirring device is continuously detected to be stuck reaches a preset number, the method further includes: outputting a third prompt to remind the user that the stirring device cannot stir, so that the user can check the cooking appliance in a timely manner.

[0027] Secondly, this application provides a control device for a cooking appliance, the cooking appliance including a stirring device, the stirring device including stirring blades; the control device includes:

This step is repeated until the stirring device is detected to be in a non-stuck state, or until the number of times the stirring device is continuously detected to be stuck reaches a preset number, at which point cooking is stopped.

[0030] In one feasible implementation, the control module is used to adjust the state of the stirring blades in at least one of the following ways:

[0031] Raise the height of the stirring blades, retract the stirring blades, or reduce the tilt angle of the stirring blades.

[0058] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] The control method for a cooking appliance provided in this application is based on a cooking appliance with a stirring device. The structure of the cooking appliance is first illustrated below. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 As shown, the cooking appliance includes a pot body 10, a pot lid 20, a heating device 30, and a stirring device 40. The stirring device 40 includes a drive device 41 and one or more stirring blades 42.

[0060] When cooking, the stirring blade 42 is submerged in the food up to near the bottom of the pot 10 for stirring. In various scenarios such as cooking large quantities of food, cooking viscous food, food that is burnt, or food that is prone to tangling, the stirring blade 42 may get stuck due to high resistance. In such cases, it may lead to damage to the stirring blade 42, overload damage to the motor in the drive device 41, or scratches on the inner wall of the pot 10, thus reducing the service life of the cooking appliance.

[0061] To address the aforementioned problems, this application proposes a control method for a cooking appliance. This method detects whether the stirring device is stuck, i.e., whether the stirring device is in a jammed state. When the stirring device is stuck, the stirring blades are adjusted and then rotated. The blades are then returned to their original position and rotated again. The method checks whether the stirring device has resumed normal operation, i.e., whether the stirring device is no longer stuck. If the stirring device is still stuck, the stirring blades can be adjusted again until the stirring device resumes normal operation. Alternatively, if the stirring device is still stuck after multiple adjustments, the cooking appliance can be stopped, thereby preventing damage to components due to the stirring device being stuck and extending the service life of the cooking appliance.

[0062] The control method for the cooking appliance provided in this application will now be described in detail through specific embodiments. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0063] Figure 4 This is a flowchart illustrating a control method for a cooking appliance provided in an embodiment of this application. The controller of the cooking appliance is the executing entity of this method. Figure 4 As shown, the method includes:

[0064] S401. Check if the stirring device is stuck.

[0065] Optionally, the controller of the cooking appliance can detect whether the stirring device is stuck by one or more of the following recognition methods: image recognition, infrared recognition, current recognition, torque recognition, speed recognition, and temperature recognition.

[0066] Optionally, the cooking appliance includes a camera device. The controller identifies the stirring blade by acquiring images captured by the camera device, thereby determining whether the stirring device is stuck. For example, if the stirring blade remains in the same position for a preset time period, the stirring device is determined to be stuck; or, if the stirring blade is bent, the stirring device is determined to be stuck.

[0067] Optionally, the cooking appliance has an infrared detection device, and the controller uses the infrared detection device to detect the position of the stirring blades, thereby determining that the stirring device is stuck.

[0068] Optionally, the controller can also determine whether the mixing device is stuck by detecting relevant parameters of the mixing motor. When the mixing blades are stuck, the mixing motor is in a stalled state. At this time, the current of the mixing motor will increase abnormally, the torque will increase abnormally, the speed will decrease abnormally or even the speed will be 0. In addition, the increase in the current of the mixing motor will cause severe heat generation and abnormal temperature rise. Therefore, the controller can determine whether the mixing device is stuck by obtaining one or more of the above parameters of the mixing motor.

[0069] S402. If the stirring device is stuck, adjust the state of the stirring blades and control the stirring device to rotate at a preset angle. Control the stirring blades to return to the state before adjustment and control the stirring device to rotate. Then check again whether the stirring device is stuck. Repeat this step until the stirring device is detected to be in a non-stuck state, or until the number of times the stirring device is detected to be stuck reaches a preset number, then stop cooking.

[0070] When the stirring device is stuck, the control can adjust the state of the stirring blades in at least one of the following ways: raise the height of the stirring blades, retract the stirring blades, or reduce the tilt angle of the stirring blades.

[0071] Raising the mixing blades can be done by partially raising them so that only the upper part of the food is in contact with the blades, or by raising them above the food. (See reference.) Figure 3 That is, the drive device 41 can control the raising of the stirring blade 42 in the direction close to the pot lid 20.

[0072] Folding up the mixing blades refers to folding the mixing blades into an umbrella shape. (See reference) Figure 3 The stirring blade 42 is retracted to a position close to the connecting shaft 43 between the stirring blade 42 and the drive device 41. Optionally, a retraction drive device 44 may be provided at the connection position between the connecting shaft 43 and the stirring blade 42. The retraction drive device 44 can control the stirring blade 42 to be retracted to a position close to the connecting shaft 43, or at a smaller angle to the connecting shaft 43.

[0073] The tilt angle of the stirring blades can affect the resistance when the stirring blades rotate. For example, when the tilt angle of the stirring blades is large, such as when the angle between the stirring blades and the bottom of the pot is 80 degrees, the resistance when the stirring blades rotate is large. When the tilt angle of the stirring blades is small, such as when the angle between the stirring blades and the bottom of the pot is 30 degrees, the resistance when the stirring blades rotate is small.

[0074] By raising the height of the mixing blades, retracting the mixing blades, or reducing the tilt angle of the mixing blades, you can move the food around the mixing blades, disperse it, and reduce the mixing resistance of the mixing blades, making it easier to mix.

[0075] After adjusting the state of the stirring blades, the stirring device can be controlled to rotate at a preset angle, for example, from 30 degrees to 180 degrees. After the stirring device rotates at the preset angle, the stirring blades are returned to their previous state, for example, by returning the stirring blades to their previous height, restoring the retracted stirring blades to their previous position, or restoring the tilt angle of the stirring blades to their previous angle. After restoring the state of the stirring blades, the stirring device is controlled to rotate again, and the stirring device is checked again for jamming according to the method in S401 described above.

[0076] After restoring the stirring blades to their original state and checking the stirring device again for any jamming, if the result shows the stirring device is not jammed (i.e., operating normally), continue cooking according to the cooking program. If the result shows the stirring device is still jammed, readjust the stirring blades, repeat the above process, and check again until the stirring device is found to be not jammed.

[0077] Alternatively, after repeatedly adjusting the state of the stirring blades and checking for jamming in the stirring device according to the above process, there may be cases where the stirring device remains jammed despite multiple adjustments. In such cases, continuing to repeat the above process may not resolve the jamming problem. Therefore, cooking can be stopped when the number of times the stirring device is continuously jammed reaches a preset number, thereby preventing damage to the components caused by the stirring device remaining jammed. Optionally, in this case, the cooking appliance can also output a third prompt to alert the user that the stirring device is not stirring, so that the user can check the cooking appliance in a timely manner.

[0078] The cooking appliance control method provided in this embodiment, when detecting that the stirring device is stuck, adjusts the stirring blades and then controls the stirring device to rotate, so that the stirring blades are freed from the current stuck state. Then, the stirring blades are returned to their previous state, and the stirring device is controlled to rotate again. The system checks whether the stirring device has resumed normal operation until it is detected that the stirring device has resumed normal operation. This avoids damage to components caused by the stirring device being stuck, thus improving the service life of the cooking appliance and preventing cooking from being affected by the stirring device being stuck, ensuring the normal operation of the cooking process. Alternatively, if the stirring device is still stuck after multiple adjustments, the cooking appliance is controlled to stop cooking, thereby avoiding damage to components caused by the stirring device being stuck and improving the service life of the cooking appliance.

[0079] Based on the above embodiments, it should be noted that when repeatedly adjusting the state of the stirring blades, the adjustment method can be the same as or different from the previous adjustment, and this embodiment does not limit this.

[0080] For example, after the first detection of a stuck stirring device, the height of the stirring blades is raised and the stirring device is rotated 30 degrees. Then, the height of the stirring blades is restored, and the stirring device is rotated again. The system then checks again to see if the stirring device is stuck. If the stirring device is still stuck on the second check, the tilt angle of the stirring blades can be reduced, and the stirring device can be rotated 30 degrees. Then, the tilt angle of the stirring blades is restored, and the stirring device is rotated again. The system then checks again to see if the stirring device is stuck. Alternatively, if the stirring device is still stuck on the second check, the height of the stirring blades can still be raised and the stirring device rotated 30 degrees. Then, the height of the stirring blades is restored, and the stirring device is rotated again. The system then checks again to see if the stirring device is stuck.

[0081] Furthermore, if the controller controls the stirring device to rotate according to a preset method during normal cooking, and when adjusting the state of the stirring blades and controlling the stirring device to rotate at a preset angle, the controller can control the stirring device to rotate at the preset angle in the same or opposite direction as the preset direction. If, after adjusting the state of the stirring blades, the controller controls the stirring device to rotate at the preset angle in the opposite direction, then after controlling the stirring blades to return to their previous state, the controller will control the stirring device to rotate in the preset direction.

[0082] For example, the controller controls the stirring device to rotate in a preset direction. Upon detecting a jammed state, the controller raises the stirring blades and rotates the device 30 degrees in the opposite direction. Then, the blade height is restored, and the device continues to rotate in the preset direction, with the controller checking for jamming again. By rotating in the opposite direction to the preset direction, food in the cooking appliance can be loosened, thus resolving the jamming problem.

[0083] For example, the controller controls the stirring device to rotate in a preset direction. After detecting that the stirring device is stuck, the height of the stirring blades is raised and the stirring device is controlled to continue rotating in the preset direction by 30 degrees. Then the height of the stirring blades is restored, the stirring device is controlled to continue rotating in the preset direction, and the stirring device is checked again to see if it is stuck.

[0084] The cooking appliances with stirring devices in the above embodiments can provide cooking functions that require stirring, as well as cooking functions that do not require stirring, such as stewing and boiling. Furthermore, the stirring blades of the stirring device can be detachable, allowing users to install the blades when using the stirring function and remove them when using the non-stirring cooking function.

[0085] Optionally, when the stirring blade is in the installed state, the cooking appliance detects whether the cooking function input by the user includes a stirring action. If so, it detects whether the stirring device is stuck. If not, it controls the cooking appliance to switch to a cooking function that includes a stirring action, or outputs a first prompt message to prompt the user to switch functions, or stops cooking.

[0086] For example, when the cooking appliance determines that the stirring blade is in the installed state, if it detects that the user-input cooking function is stir-fry mode, which requires stirring and flipping in stewing mode, it continues to detect whether the stirring device is stuck and executes the subsequent process according to the method of the above embodiment. Alternatively, when the cooking appliance determines that the stirring blade is in the installed state, if it detects that the user-input cooking function is soup mode, which does not require stirring, the cooking appliance can automatically switch to a cooking function that includes stirring; or, it can prompt the user to manually switch by outputting a first prompt message; or, the cooking appliance can stop cooking and wait for the user to select a cooking function again.

[0087] Optionally, when the cooking appliance determines that the stirring blade is not installed, it detects whether the cooking function input by the user does not include stirring. If so, cooking continues; if not, it outputs a prompt message to remind the user to install the stirring blade. After the user installs the stirring blade, it can detect whether the stirring blade is stuck in the above embodiment.

[0088] By confirming the match between the user's selected cooking function and the installation status of the stirring blade, the cooking effect is avoided due to improper user operation.

[0089] Optionally, after the user installs the stirring blades, the cooking appliance can also detect whether the stirring blades are installed correctly. If the stirring blades are installed correctly, it will detect whether the stirring device is stuck. If the stirring blades are installed incorrectly, it will output a second prompt message to remind the user to install them correctly, or stop cooking. This avoids inaccurate subsequent detection results due to improper installation of the stirring blades by the user.
