Users usually clean the inner pot (or suction cup) after each use, but most users don't clean it or clean the fan blades very little. The long-term accumulation of oil will produce odors and affect cooking performance. Summary of the Invention

[0036] The embodiments of this application are described in detail below, and examples of these embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0038] The "cooking appliance" used in this embodiment includes, but is not limited to, rice cookers, pressure cookers, air fryers, etc. This application uses an air fryer as an example for illustration.

[0039] In existing technologies, when using cooking appliances such as air fryers, users usually remove the inner pot of the air fryer and clean the cooking chamber after cooking. Since the fan blades of the air fryer are located in a relatively hidden position, they are difficult to clean. Users usually do not clean the fan blades separately. However, during the cooking process, the food surface is prone to oil splattering at high temperatures. The inside of the cooking chamber and the surface of the fan blades are easily splashed with oil. If the fan blades are not cleaned for a long time, oil stains will accumulate over time, producing odors and affecting cooking performance.

[0040] Therefore, the inventors of this application have proposed a method, apparatus, control device, and computer-readable storage medium for self-cleaning cooking appliance fan blades according to embodiments of this application to improve the above-mentioned problems. The technical solutions in the embodiments of this application will now be clearly and completely described with reference to the accompanying drawings.

[0041] Please see Figure 1 , Figure 1 The structure of a cooking appliance 1 is shown. The cooking appliance 1 may include: a pot body 10, a lid 20, a coil (not shown), a motor (not shown), a fan blade 50, a temperature sensor (not shown), and a controller (not shown).

[0042] Please also refer to Figure 2 The pot body 10 may include a shell 110 and an inner pot 120. The inner pot 120 is detachably disposed within the shell 110, and its hollow interior forms a cooking cavity 121, which can be used to hold food to be cooked. The pot body 10 may be configured as a roughly cubic or cuboid structure, and the inner pot 120 may be configured as a bowl-shaped or cylindrical structure, etc., without limitation. It is understood that the inner pot 120 may be made of stainless steel, ceramic, aluminum alloy, or composite materials. Stainless steel inner pots have good corrosion resistance, heat resistance, wear resistance, and easy cleaning. Ceramic inner pots have high temperature resistance, corrosion resistance, good heat retention, and easy cleaning, and are also rich in trace elements beneficial to the human body. Aluminum alloy inner pots have good thermal conductivity, strong corrosion resistance, and light weight, but are easily scratched and require careful maintenance. Composite material inner pots are made of multiple materials and have good thermal conductivity, wear resistance, and corrosion resistance. The specific choice can be made based on the actual situation, and no restrictions are imposed here.

[0043] The top cover 20 is rotatably mounted on the housing 110 and is used to close the housing 110. It can also selectively open or close the cooking cavity 121. The top cover 20 can be hinged to the housing 110 so that it remains connected to the housing 110 even when opened, eliminating the need for the user to remove the top cover 20 separately, thus facilitating user operation.

[0044] A coil disk 30 is disposed on the upper cover 20 and is used to heat the fan blade 50. In this embodiment, the coil disk can use induction heating (IH) to heat the fan blade 50. The coil disk 30 can be a coil, and the fan blade 50 can be a magnetic component. There are no limitations. For example, in some other embodiments, the coil disk can also use a heating wire, graphene, or a ceramic lamp to generate heat to heat the fan blade 50. The specific choice can be made according to the actual situation.

[0045] In this embodiment, the coil 30 can heat the fan blade 50 to decompose the grease adhering to it. It should be noted that the grease adhering to the fan blade 50 is mainly composed of a mixture of various lipids, including saturated fatty acids, unsaturated fatty acids, and cholesterol. At high temperatures, these greases oxidize, polymerize, and decompose; specifically, the decomposition temperature of these greases is typically 250°C.

[0046] The motor 40 can be mounted on the upper cover 20 and connected to the fan blade 50 to drive the fan blade 50 to rotate. For example, the motor 40 can have an output shaft, which can be connected to the center of the fan blade 50. When the motor 40 rotates, the output shaft can drive the fan blade 50 to rotate synchronously.

[0047] The fan blade 50 is disposed on the upper cover 20 and is used to blow hot air into the inner pot 120 to form an airflow circulation in the cooking cavity 121, thereby cooking the food. Specifically, the axis of the fan blade 50 can be aligned with the axis of the inner pot 120, so that more air blown out by the fan blade 50 can enter the cooking cavity 121, which helps to make the hot airflow distribution in the cooking cavity 121 more even.

[0048] The temperature sensor can be used to obtain the temperature of the fan blade 50 or the temperature of the cooking cavity 121. For example, the temperature sensor can be located on the side of the fan blade 50 away from the heating unit 30. This avoids direct heat transfer from the heating unit 30 to the temperature sensor, which helps improve the accuracy of the temperature sensor's detection of the fan blade 50. It is understood that the temperature sensor can be a thermistor (NTC), thermocouple, integrated temperature sensor, or digital temperature sensor, etc., and the specific choice can be made according to the actual situation; no restrictions are imposed here.

[0049] The controller can be electrically connected to the coil 30, motor 40, fan blades 50, and temperature sensor, and can issue commands to the coil 30, motor 40, and temperature sensor. For example, the controller can issue a heating command to the coil 30, an on / off command to the motor 40, and a temperature acquisition command to the temperature sensor. In addition, the controller can also be used to acquire the motor's operating parameters and adjust the output power of the coil.

[0050] The cooking appliance 1 described above can respond to the self-cleaning command through the controller and start the coil 30 and motor 40 to drive the fan blade 50 to rotate and heat the fan blade. Then, the temperature of the fan blade 50 and the operating parameters of the motor 40 are obtained, and the output power of the coil 30 is adjusted according to the temperature so that the temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold. Until the operating parameters of the motor 40 are greater than the first parameter threshold, the controller can control the motor 40 and the coil 30 to turn off.

[0051] First embodiment:

[0052] This embodiment provides a method for self-cleaning the fan blades of a cooking utensil. (See attached document.) Figure 3 The method includes the following steps S110-S150:

[0053] Step S110: In response to the self-cleaning command, start the coil disk and motor to drive the fan blades to rotate.

[0054] The self-cleaning instruction refers to the instruction or operation of a cooking appliance to automatically clean and remove dust, dirt, and other impurities from the fan blades after cooking. This instruction is designed to keep the fan blades clean and function properly, preventing performance degradation or unpleasant odors caused by dust, dirt, and other impurities.

[0055] The self-cleaning command can be triggered by pressing a physical button on the cooking appliance, by voice activation via a voice receiver module within the appliance, or by remote operation using a mobile device such as a smartphone; there are no limitations on this. In some implementations, the self-cleaning command can also be pre-set by the user to run automatically after a certain period of time. This allows for advance scheduling, meaning the cooking appliance can enter self-cleaning mode even when the user is not nearby, improving the convenience of operation. For example, a user can pre-set the cooking appliance to automatically run the self-cleaning operation 5 minutes after cooking is complete, avoiding the need for the user to return to the cooking appliance after cooking and removing the food.

[0056] When the cooking appliance receives the self-cleaning command, the controller can start the coil to heat the fan blades. The high temperature will break down the grease adhering to the fan blades. At the same time, the controller can start the motor to rotate the fan blades. The rotation of the fan blades will fling off the grease adhering to the fan blades, thus achieving the self-cleaning operation of the fan blades.

[0057] For example, in some implementations, the controller can also control the speed of the motor, and thus control the speed of the fan blades. It is understood that in the initial stage of the coil's startup, the temperature of the fan blades has not reached the temperature required for self-cleaning. Therefore, even if the fan blades are controlled to rotate at high speed at this time, it is difficult to shake off the grease. Therefore, the controller can gradually increase the speed of the motor according to the operating parameters of the motor, so that the speed of the motor increases with the increase of the fan blade temperature. This can achieve the effect of energy saving and avoid energy waste.

[0058] For example, in one specific implementation, when the motor runs for 0-5 minutes, the controller can control the motor to run at 600 rad / min. At this time, the motor speed is relatively slow, and the grease on the fan blades is still in an undecomposed state. The slow rotation of the fan blades driven by the motor allows the coil to heat the fan blades more evenly and fully. When the motor runs for 5-10 minutes, the controller can control the motor to run at 3000 rad / min. At this time, the motor speed is relatively fast, and the grease on the fan blades is also in the process of decomposition. The rapid rotation of the fan blades driven by the motor allows the outer layer of grease on the fan blades to be decomposed and thrown into the cooking cavity, thereby facilitating the high-temperature decomposition of the inner layer of grease on the fan blades.

[0059] Step S120: Obtain the temperature of the fan blades or cooking cavity and the operating parameters of the motor.

[0060] The operating parameters may include at least one of the following: operating duration or operating stages. In one implementation, the operating parameters include the operating duration. The operating duration refers to the operating time of the motor, and the operating stages refer to different preset program stages.

[0061] As mentioned earlier, after the cooking appliance performs self-cleaning, the controller can obtain the temperature of the fan blades. Specifically, the controller can obtain the temperature from the temperature sensor and use the temperature of the temperature sensor as the temperature of the fan blades. At the same time, the controller can also obtain the operating parameters of the motor to control the self-cleaning process. It can be understood that obtaining the operating parameters of the motor here refers to the interval between the controller controlling the motor to start and the controller obtaining the operating parameters of the motor.

[0062] Step S130: Adjust the output power of the coil according to the temperature so that the temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold.

[0063] As mentioned above, in this embodiment, the controller can adjust the output power of the coil based on the temperature of the temperature sensor. For example, when the temperature of the temperature sensor is low, the controller can control the output power of the coil to increase, providing high power output so that the fan blades can heat up quickly to reach the decomposition temperature of the grease. When the temperature of the temperature sensor is high, the controller can control the output power of the coil to decrease, providing low power output so that the fan blades can heat up slowly to reach the decomposition rate of the grease, avoiding the temperature rising too quickly and causing the temperature to exceed the second temperature threshold, thus preventing safety hazards. Ultimately, the temperature is controlled between the first temperature threshold and the second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold.

[0064] It should be noted that the first temperature threshold here can be the decomposition temperature of the grease, and the second temperature threshold can be the maximum temperature. By controlling the temperature of the temperature sensor between the first and second temperature thresholds, the grease on the fan blades can be decomposed by high temperature, while avoiding the safety hazards caused by excessive temperature.

[0065] For example, in some embodiments, the first temperature threshold can be 250°C, and the second temperature threshold can be 260°C-280°C. Specifically, the second temperature threshold can be set to 260°C, 270°C, or 280°C. Preferably, since grease usually decomposes at 250°C, the second temperature threshold can be controlled at 260°C. This avoids safety hazards caused by excessively high temperatures while still achieving the effect of decomposing grease.

[0066] It is understandable that in some other implementations, such as when the cooking appliance has not been cleaned or self-cleaned for a long time, the second temperature threshold can be controlled at 280°C. It is understood that when the grease on the fan blades is not cleaned in time for a long time, the difficulty of subsequent cleaning will increase, and the temperature required to decompose the grease that has accumulated over a long period of time is also higher. Therefore, controlling the second temperature threshold at 280°C can make the grease that has accumulated over a long period of time on the fan blades more fully decomposed.

[0067] For further details, please refer to Figure 4 In this embodiment, step S130: Adjusting the output power of the coil according to the temperature so that the temperature is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold, may include sub-steps S131-S134:

[0068] Step S131: When the temperature is greater than the first temperature threshold and less than or equal to the second temperature threshold, control the coil to heat in the first output mode so that the temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold.

[0069] As mentioned above, when the sensor temperature is greater than the first temperature threshold, it indicates that the current temperature has reached the decomposition temperature of the oil. At this time, the controller can control the coil to heat in the first output mode. Specifically, the controller can control the coil to heat with the first output power.

[0070] It should be noted that the first output mode here can be a low-power output mode, and the first output power can be low-power. For example, the output power of the coil can be set to 300W. This makes it easier to control the temperature between the grease decomposition temperature and the maximum temperature, avoiding excessive output power of the coil during the process, which would cause the fan blade temperature to rise sharply and create a safety hazard. At the same time, using low-power output can save energy.

[0071] Step S132: When the temperature is less than or equal to the third temperature threshold, control the coil to heat in the second output mode so that the temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold.

[0072] As mentioned above, when the temperature is lower than the third temperature threshold, it means that the current temperature has not yet approached the decomposition temperature of the oil. At this time, the controller can control the heating unit to heat in the second output mode. Specifically, the controller can control the coil to heat with the second output power.

[0073] Similarly, the second output mode here can be a high-power output mode, and the second output power can be high-power. This means the second output power can be greater than the first output power. For example, the output power of the coil can be set to 900W, which facilitates the rapid increase in temperature to the decomposition temperature of the grease, thus decomposing the grease adhering to the fan blades. This helps to shorten the overall self-cleaning time and improve the efficiency of self-cleaning.

[0074] For further information, please refer to [link / reference]. Figure 4 In one embodiment, step S130: adjusting the output power of the coil according to the temperature so that the temperature is greater than or equal to a first temperature threshold and less than or equal to a second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold, may further include:

[0075] Step S133: When the temperature of the temperature sensor is greater than the second temperature threshold, the control coil is turned off so that the temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold.

[0076] As mentioned above, when the temperature is greater than or equal to the second temperature threshold, it means that the current temperature has reached or exceeded the maximum temperature. For safety and energy-saving reasons, the controller can control the heating unit to turn off at this time. In other words, the output power of the heating unit can be set to 0. After the heating unit stops heating, the residual heat can be used to continue to decompose the grease.

[0077] It is understandable that during the process of the coil heating the fan blades, due to various factors such as ambient temperature or controller detection delay, the temperature of the fan blades will gradually decrease when the coil is turned off or when the coil is heating at low power.

[0078] When the heating unit is turned off or heated at low power, the temperature of the fan blades drops from the first temperature threshold to below the first temperature threshold. At this time, the temperature of the fan blades is between the third temperature threshold and the first temperature threshold, and the heating unit can output at low power.

[0079] Step S134: When the temperature of the temperature sensor is greater than the third temperature threshold and less than the first temperature threshold, the control coil disk outputs in the third output mode.

[0080] The third output mode can output power according to the set output power of the coil during the previous heating process.

[0081] Understandably, since the heating unit has a low output power, it takes a certain amount of time for the heating unit to provide enough heat to decompose the grease on the fan blades. If, during this period, the fan blades' temperature decreases faster than the heating unit's temperature rises, the fan blades' temperature may fall below the third temperature threshold. In this case, the controller can control the heating unit to output at high power. With the heating unit's output power at high power, the heating unit's temperature rises faster than the fan blades' temperature decreases, thus causing the fan blades' temperature to rise. When the fan blades' temperature rises from below the third temperature threshold to between the third and first temperature thresholds, the heating unit can then output at high power, thus avoiding frequent switching of the heating unit's output mode.

[0082] In addition, when the cooking appliance first starts its self-cleaning function for the fan blades, the temperature of the heating unit is 0 and gradually rises. At this time, the temperature of the fan blades is less than the third temperature threshold, and the controller controls the heating unit to output high power. The output power of the heating unit is high power. When the temperature of the fan blades rises from less than the third temperature threshold to between the third temperature threshold and the first temperature threshold, the heating unit can output high power. This also avoids frequent switching of the output mode of the heating unit.

[0083] Step S140: Determine whether the motor's operating parameters meet the preset conditions.

[0084] As mentioned above, the motor's operating parameters can be used to reflect the progress of the fan blades' self-cleaning. When the motor's operating parameters, such as the running length, exceed the first parameter threshold, it can be determined that the motor's operating parameters meet the preset conditions, and that the fan blades' self-cleaning has been completed. In this embodiment, when the operating parameters include the running length, the first parameter threshold can be 10-20 minutes. Specifically, it can be 10 minutes, 15 minutes, or 20 minutes, etc., without limitation. For example, when the user performs the fan blades' self-cleaning operation every time after cooking with cooking utensils, the first parameter threshold can be set to 10 minutes. When the user performs the fan blades' self-cleaning once a week, the first parameter threshold can be set to 15 minutes. When the user performs the fan blades' self-cleaning once every two weeks, the first parameter threshold can be set to 20 minutes, etc. The specific settings can be made according to the actual situation, without limitation.

[0085] In addition, in some implementations, the first parameter threshold can be set by the user. For example, the user can set the first parameter threshold to any value not less than 10 minutes, such as 30 minutes, 40 minutes, etc. The specific value can be selected according to the user's needs, and there are no restrictions here.

[0086] It is understandable that the longer the operating parameters of the motor, such as the running time, the higher the self-cleaning degree of the fan blades. However, taking into account the actual situation and the cost of use, the first parameter threshold is preferably 15 minutes.

[0087] In some implementations, the operating parameters may include operating phases, such as a preset self-cleaning program. When the self-cleaning program phase is completed, the preset parameters can be considered to meet the preset conditions.

[0088] Step S150: Turn off the motor and the coil.

[0089] As mentioned above, when the operating parameters of the motor meet the preset conditions, it can be determined that the self-cleaning of the fan blades has been completed. At this time, the motor can be turned off so that the fan blades gradually stop rotating. At the same time, the coil can be turned off so that the coil can gradually cool down, and finally the self-cleaning of the fan blades is completed.

[0090] It should be noted that after the fan blades have finished self-cleaning, the grease on them will be broken down and shaken into the inner pot of the cooking appliance. At this point, the inner pot can be removed for cleaning. In actual use, after cooking, the user can open the lid, remove the food, close the lid, and issue a self-cleaning command to the cooking appliance. The self-cleaning process usually takes less than 20 minutes, during which time the user can eat. After finishing eating, the user can open the lid and remove the inner pot for cleaning.

[0091] The self-cleaning method for cooking appliance fan blades provided in this application embodiment activates a coil and motor to drive the fan blades to rotate in response to a self-cleaning command. The coil heats the fan blades, causing the grease adhering to the fan blades during cooking to decompose. Then, the fan blades rotate to fling the decomposed grease off the fan blades, thus achieving a self-cleaning operation. The decomposed grease can be flung into the inner pot of the cooking appliance, allowing the user to clean the inner pot. This solves the problem in the prior art where most users do not clean or clean the fan blades infrequently, leading to long-term accumulation of grease, which produces odors and affects cooking performance.

[0092] Second embodiment:

[0093] Please see Figure 5 This application also provides another method for self-cleaning the fan blades of a cooking appliance, the method including the following steps S210-S260. It should be understood that the method for self-cleaning the fan blades of a cooking appliance in this embodiment has the same or corresponding implementation steps as the above embodiments. The specific description of these same or corresponding implementation steps can be referred to the content provided in the above embodiments, and will not be repeated in this embodiment.

[0094] Step S110: In response to the self-cleaning command, start the coil disk and motor to drive the fan blades to rotate.

[0095] Step S120: Obtain the temperature of the fan blades or cooking cavity and the operating parameters of the motor.

[0096] Step S130: Adjust the output power of the coil according to the temperature so that the temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold.

[0097] Step S140: Determine whether the motor's operating parameters meet the preset conditions.

[0098] If so, proceed to step S150: shut down the motor and the coil.

[0099] Step S160: Issue a prompt message to inform the user that the self-cleaning operation has ended.

[0100] As mentioned above, after the cooking appliance completes its self-cleaning operation, the controller will turn off the motor and coil. At this time, the controller can also issue a prompt message to remind the user that the self-cleaning operation has ended.

[0101] It should be noted that the embodiments of this application do not limit the specific form of the above-mentioned prompt information. For example, when the cooking appliance has a sound module, the above-mentioned prompt information can be an audio prompt; when the cooking appliance has a display module, the above-mentioned prompt information can also be a video display prompt; when the cooking appliance has a signal transmission module, the above-mentioned prompt information can also be a push notification sent to the user terminal, etc. This makes it easier for users to understand the progress of the fan blade self-cleaning more intuitively.

[0102] In addition, the prompts here can also be used to remind users to clean the cooking cavity of the inner pot. During the self-cleaning process of the cooking appliance's blades, the grease on the blades is decomposed by the high temperature and eventually falls into the cooking cavity under the swing of the blades. At this time, users only need to clean the inner pot.

[0103] For example, after a user finishes cooking with the cooker, the user can remove the food from the inner pot and then issue a self-cleaning command to the cooker. The cooker will then self-clean the fan blades. Once the self-cleaning is complete, the cooker can notify the user that the self-cleaning is finished. After the user finishes eating, the user can remove the inner pot and clean it directly, which simplifies the cleaning process.

[0104] The self-cleaning method for cooking appliance fan blades provided in this application embodiment activates a coil and motor to drive the fan blades to rotate in response to a self-cleaning command. The coil heats the fan blades, causing the grease adhering to the fan blades during cooking to decompose. The decomposed grease is then flung off the fan blades by the rotation of the fan blades, thus achieving a self-cleaning operation. The decomposed grease can be flung into the inner pot of the cooking appliance. When the self-cleaning operation of the fan blades is completed, the cooking appliance can issue a prompt message, allowing the user to clean the inner pot. This solves the problem in the prior art where most users do not clean or clean the fan blades infrequently, leading to long-term accumulation of grease, which produces odors and affects cooking performance.
