Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a cooking appliance, a control method for multiple lifting structures in the cooking appliance, a cooking control method for the cooking appliance, an electronic device, and a storage medium. Background Technology

[0002] In the field of home appliances, cooking appliances such as rice cookers are widely used and have almost become one of the essential kitchen appliances in every household. As living standards improve, people have higher and higher requirements for heating methods and precision in the cooking process, and therefore, higher and higher requirements for cooking appliances.

[0003] Cooking appliances are prone to overflowing during heating, especially in special environments such as high altitudes. To prevent this, the heating power can be reduced through the appliance's program settings, but this will affect the cooking results.

[0004] Existing technology uses a blower to prevent overflow. The blower directs cold air into the inner pot, breaking up bubbles and preventing the rice cooker from overflowing. However, this type of cooking appliance with a blower tends to generate significant noise when the blower is operating, which can seriously disturb the user's rest. Solutions that partially reduce blower noise, on the other hand, may reduce the effectiveness of the overflow prevention mechanism. Summary of the Invention

[0005] In order to at least partially solve the problems existing in the prior art, a heating control method and system for a cooking appliance, a cooking appliance, and a storage medium are provided.

[0006] According to one aspect of the present invention, a cooking appliance is provided, including a pot body, the pot body including an inner pot and a plurality of lifting mechanisms, the inner pot being supported on the plurality of lifting mechanisms; the plurality of lifting mechanisms are used to form multiple back-and-forth height combinations during the execution of a target cooking function, so that the inner pot sways during the execution of the target cooking function, wherein each of the plurality of lifting mechanisms has a corresponding rising height in each formed height combination.

[0007] According to embodiments of the present invention, the cooking appliance can utilize multiple lifting mechanisms to create alternating height combinations during the execution of the target cooking function, causing the inner pot to sway and thus helping to prevent boiling over. This solution eliminates the need for a blower, thereby reducing appliance noise to some extent while ensuring anti-overflow effectiveness and without affecting cooking efficiency. This anti-overflow solution effectively improves the user experience.

[0008] For example, the pot body also includes a heating device disposed between the inner pot and multiple lifting mechanisms, the inner pot being supported on the multiple lifting mechanisms by the heating device.

[0009] Therefore, the inner pot is supported on multiple lifting mechanisms by a heating device, which achieves anti-overflow while maintaining the heating effect on the inner pot.

[0010] For example, any one of the multiple lifting mechanisms includes a motor and a transmission rod, with a cam provided on the output shaft of the motor and the transmission rod provided on the cam.

[0011] Therefore, cams are simple to implement and have low cost.

[0012] For example, the pot body also includes a heating device, which is disposed between the inner pot and multiple lifting structures. The inner pot is supported on the multiple lifting mechanisms by the heating device. The transmission rod is fixed on the heating device, and a recess is provided at the end of the transmission rod that contacts the cam. The recess can fit into the protrusion on the cam.

[0013] Therefore, the recessed part at the end of the transmission rod that contacts the cam allows the transmission rod and the cam to fit more tightly, preventing the transmission rod from falling off during motor rotation.

[0014] For example, the cooking appliance also includes a lid that is closable on the pot body. When the lid is fastened to the pot body, it forms a cooking space. The lid includes a removable cover and a top cover, which are connected by a ball joint; and / or, at least one elastic element is provided between the removable cover and the top cover.

[0015] Therefore, the structure based on at least one elastic element allows for a tighter fit between the removable lid and the inner pot, preventing poor sealing between the inner pot and the lid when shaken. The spherical connector enables multi-angle rotation, reducing resistance when the inner pot shakes and minimizing frictional wear between structural components after prolonged use.

[0016] For example, the spherical connector has a cavity in which a top temperature sensor is disposed for detecting the top temperature in the cooking space.

[0017] Therefore, placing the top temperature sensor within the cavity saves space in the cooking appliance. It also prevents the top temperature sensor from contacting other structures, thus extending its lifespan.

[0018] For example, the cooking appliance also includes a controller for performing a shaking operation to control multiple lifting mechanisms to form multiple combinations of varying heights during the execution of the target cooking function.

[0019] Therefore, the shaking operation can be performed automatically by the controller. This solution is more intelligent and requires no user intervention, thus improving the user experience.

[0020] For example, the swaying operation includes performing at least one height change operation on a plurality of lifting mechanisms, each height change operation including: controlling at least one group of lifting mechanisms among the plurality of lifting mechanisms to rise to a maximum height, wherein the plurality of lifting mechanisms are divided into multiple groups of lifting mechanisms; and cyclically performing the following lifting operations: controlling at least some groups of lifting mechanisms that have risen to the maximum height to fall to the minimum height, and controlling at least some groups of lifting mechanisms that are currently at the minimum height to rise to the maximum height.

[0021] According to the above technical solution, the swaying operation is achieved by controlling multiple lifting mechanisms to sequentially perform height change operations. The height change operation in this solution mainly relies on the cyclic execution of lifting operations; the control logic is relatively simple and easy to implement, thus resulting in low cost.

[0022] For example, the lifting operation specifically includes: controlling a group of lifting mechanisms adjacent to the first group of lifting mechanisms along the first direction to rise to the maximum height, and controlling a second group of lifting mechanisms to fall to the minimum height. The first group of lifting mechanisms is the group of lifting mechanisms that are currently at the front along the first direction among the lifting mechanisms that have risen to the maximum height, and the second group of lifting mechanisms is the group of lifting mechanisms that are currently at the back along the first direction among the lifting mechanisms that have risen to the maximum height.

[0023] According to the above technical solution, each time, the first set of lifting mechanisms adjacent to the first set of lifting mechanisms (which is located at the forefront along the first direction) is controlled to rise to the maximum height, and the second set of lifting mechanisms (which is located at the rearmost along the first direction) is controlled to descend to the minimum height, thereby achieving height change. This method ensures orderly lifting and lowering, making the shaking of the inner pot more stable and orderly, which helps reduce wear and tear on cooking utensils and provides a better user experience.

[0024] For example, the grouping of multiple lifting mechanisms is different in at least two different height change operations, and / or the execution speed of the lifting operations is different in at least two different height change operations.

[0025] Therefore, during the shaking operation, the method of changing the height can be changed at least once, which can achieve a more varied shaking effect, help to achieve better cooking results and prevent spills, and further improve the user experience.

[0026] For example, the controller is further configured to: receive an execution instruction for any target cooking function; execute the target cooking function based on the execution instruction; wherein the controller is specifically configured to perform a shaking operation during at least one cooking period in the execution of the target cooking function.

[0027] In the above technical solution, the controller can receive and execute instructions for any target cooking function, and automatically perform the shaking operation during at least one cooking period in the process of executing the target cooking function to achieve the shaking effect. This can improve the intelligence and automation of cooking appliances and enhance their ease of use.

[0028] For example, the cooking appliance also includes a top temperature sensor for detecting the top temperature of the cooking space of the cooking appliance, and the controller is specifically configured to: perform a first shaking operation when the top temperature is greater than a first temperature threshold and less than a second temperature threshold, wherein the lifting operation in the first shaking operation has a first execution speed; and / or perform a second shaking operation when the top temperature is greater than the second temperature threshold, wherein the lifting operation in the second shaking operation has a second execution speed; wherein the first temperature threshold is less than the second temperature threshold, and the difference between the second temperature threshold and a preset top boiling temperature is less than the first temperature difference threshold.

[0029] According to the above technical solution, when the temperature at the top indicates that the water is close to boiling or has basically reached the boiling state, at least one shaking operation can be performed. This can accelerate the uniformity of the water temperature in the pot before boiling and accelerate the balance of the upper and lower temperatures, thereby helping to better prevent overflow.

[0030] For example, the first execution speed is greater than the second execution speed; and / or, the first execution speed and / or the second execution speed are determined based on the rate of change of the top temperature.

[0031] This setting allows for flexible speed settings, resulting in better overflow prevention.

[0032] For example, the target cooking function is a porridge cooking function, and the controller is specifically used to: heat with a first power when the top temperature is less than a third temperature threshold until the top temperature reaches the third temperature threshold, and the third temperature threshold is less than the first temperature threshold; after the top temperature reaches the third temperature threshold, heat with a second power until the top temperature reaches the second temperature threshold; wherein, the first power is greater than the second power.

[0033] According to the above technical solution, during the porridge-cooking process, different power levels can be used to heat the food at different top temperatures. This ensures cooking quality. Furthermore, by setting the first power to be greater than the second power, the heating power of the heating device can be gradually reduced as the top temperature rises, thus guaranteeing the optimal cooking effect.

[0034] For example, the controller is further configured to: heat with a third power after the top temperature reaches a second temperature threshold until the entire cooking time of the target cooking function is over; wherein the second power is greater than the third power.

[0035] This design allows for different power levels to be used for heating at different top temperatures during the porridge-cooking process. This ensures cooking quality. Furthermore, setting the second power to be greater than the third power allows for a gradual reduction in the heating power as the top temperature rises, thus maintaining optimal food cooking results.

[0036] For example, the target cooking function is a rice cooking function, and the cooking appliance also includes a bottom temperature sensor for detecting the temperature of the inner pot of the cooking appliance. The controller is specifically used to: when the bottom temperature is within a preset range around a fourth temperature threshold, perform a third shaking operation until the preset water absorption time ends, and the lifting operation in the third shaking operation has a third execution speed.

[0037] According to the above technical solution, a bottom temperature sensor installed in the cooking appliance can detect the bottom temperature, and then determine whether to perform a third shaking operation based on the bottom temperature value. This method can automatically perform a shaking operation when the rice cooking function reaches the water absorption stage, ensuring that the upper and lower layers of rice absorb water to the same degree, which greatly improves subsequent overflow prevention and cooking effect.

[0038] For example, executing the target cooking function based on the execution instruction further includes: heating with a fourth power when the bottom temperature is less than a fourth temperature threshold until the bottom temperature reaches the fourth temperature threshold; heating with a fifth power after the bottom temperature reaches the fourth temperature threshold to maintain the bottom temperature within a preset range around the fourth temperature threshold until the preset water absorption time ends; heating with a sixth power after the preset water absorption time ends until the top temperature reaches a second temperature threshold; and heating with a seventh power after the top temperature reaches the second temperature threshold until the entire cooking time of the target cooking function ends.

[0039] According to the above technical solution, by detecting the bottom temperature and the top temperature, the corresponding power is used for heating when the temperature is at different stages, which can achieve better cooking results and improve the user experience.

[0040] For example, each lifting mechanism includes a motor, and the controller is specifically configured to: control at least some of the lifting mechanisms to simultaneously rise to a maximum height after receiving an execution instruction for any target cooking function and before executing the target cooking function based on the execution instruction; detect the load current of the motors in at least some of the lifting mechanisms during operation; determine the amount of food in the inner pot based on the load current; and determine the execution speed of the lifting operation in each heating power and / or each shaking operation during the execution of the target cooking function based on the amount of food.

[0041] According to the above technical solution, the amount of food in the inner pot is determined based on the motor's load current, which in turn determines the heating power and / or the lifting speed of each shaking operation during the execution of the target cooking function. Therefore, different amounts of food can be cooked with matched heating power or shaking speed to achieve better cooking results.

[0042] For example, the larger the amount of food, the greater the heating power during the execution of the target cooking function, and / or the smaller the execution speed of the lifting operation in the same shaking operation during the execution of the target cooking function.

[0043] According to the above technical solution, the heating power and / or the lifting speed during the same shaking operation can be adjusted based on the amount of food consumed. This can meet the cooking needs of different cooking functions, thereby achieving better cooking results.

[0044] For example, for any cooking period, a preset time interval is between every two adjacent height change operations in the corresponding shaking operation.

[0045] According to the above technical solution, compared with the continuous shaking solution, the intermittent shaking solution can save power consumption to a certain extent.

[0046] According to a second aspect of the present invention, a control method for multiple lifting structures in a cooking appliance is also provided. The cooking appliance includes a pot body, the pot body includes an inner pot and multiple lifting mechanisms, the inner pot is supported on the multiple lifting mechanisms, and the method includes: performing a shaking operation to control the multiple lifting mechanisms to form multiple back-and-forth changing height combinations during the execution of a target cooking function, so that the inner pot shakes during the execution of the target cooking function, wherein each of the multiple lifting mechanisms has a corresponding rising height in each formed height combination.

[0047] According to the above technical solution, the shaking operation can be performed automatically. This solution is more intelligent and requires no user intervention, thus improving the user experience.

[0048] For example, the swaying operation includes performing at least one height change operation on a plurality of lifting mechanisms, each height change operation including: controlling at least one group of lifting mechanisms among the plurality of lifting mechanisms to rise to a maximum height, wherein the plurality of lifting mechanisms are divided into multiple groups of lifting mechanisms; and cyclically performing the following lifting operations: controlling at least some groups of lifting mechanisms that have risen to the maximum height to fall to the minimum height, and controlling at least some groups of lifting mechanisms that are currently at the minimum height to rise to the maximum height.

[0049] According to the above technical solution, the swaying operation is achieved by controlling multiple lifting mechanisms to sequentially perform height change operations. The height change operation in this solution mainly relies on the cyclic execution of lifting operations; the control logic is relatively simple and easy to implement, thus resulting in low cost.

[0050] For example, the lifting operation specifically includes: controlling a group of lifting mechanisms adjacent to the first group of lifting mechanisms along the first direction to rise to the maximum height, and controlling a second group of lifting mechanisms to fall to the minimum height. The first group of lifting mechanisms is the group of lifting mechanisms that are currently at the front along the first direction among the lifting mechanisms that have risen to the maximum height, and the second group of lifting mechanisms is the group of lifting mechanisms that are currently at the back along the first direction among the lifting mechanisms that have risen to the maximum height.

[0051] According to the above technical solution, each time, the first set of lifting mechanisms adjacent to the first set of lifting mechanisms (which is located at the forefront along the first direction) is controlled to rise to the maximum height, and the second set of lifting mechanisms (which is located at the rearmost along the first direction) is controlled to descend to the minimum height, thereby achieving height change. This method ensures orderly lifting and lowering, making the shaking of the inner pot more stable and orderly, which helps reduce wear and tear on cooking utensils and provides a better user experience.

[0052] For example, the grouping of multiple lifting mechanisms is different in at least two different height change operations, and / or the execution speed of the lifting operations is different in at least two different height change operations.

[0053] Therefore, during the shaking operation, the method of changing the height can be changed at least once, which can achieve a more varied shaking effect, help to achieve better cooking results and prevent spills, and further improve the user experience.

[0054] According to a third aspect of the present invention, a cooking control method for a cooking appliance is also provided, the cooking appliance including a pot body, the pot body including an inner pot and a plurality of lifting mechanisms, the inner pot being supported on the plurality of lifting mechanisms, the method comprising: receiving an execution command for any target cooking function; executing the target cooking function based on the execution command, and performing the aforementioned shaking operation respectively during at least one cooking period in the execution of the target cooking function.

[0055] In the above technical solution, an execution command for any target cooking function can be received and executed, and the aforementioned shaking operation can be automatically performed during at least one cooking period in the execution of the target cooking function to achieve a shaking effect. This enhances the intelligence and automation of the cooking appliance, and improves its ease of use.

[0056] For example, the cooking appliance also includes a top temperature sensor for detecting the top temperature of the cooking space of the cooking appliance, and performs the above-mentioned shaking operation during at least one cooking period in the execution of the target cooking function, including: performing a first shaking operation when the top temperature is greater than a first temperature threshold and less than a second temperature threshold, wherein the lifting and lowering operation in the first shaking operation has a first execution speed; and / or performing a second shaking operation when the top temperature is greater than the second temperature threshold, wherein the lifting and lowering operation in the second shaking operation has a second execution speed; wherein the first temperature threshold is less than the second temperature threshold, and the difference between the second temperature threshold and the preset top boiling temperature is less than the first temperature difference threshold.

[0057] According to the above technical solution, when the temperature at the top indicates that the water is close to boiling or has basically reached the boiling state, at least one shaking operation can be performed. This can accelerate the uniformity of the water temperature in the pot before boiling and accelerate the balance of the upper and lower temperatures, thereby helping to better prevent overflow.

[0058] For example, the first execution speed is greater than the second execution speed; and / or, the first execution speed and / or the second execution speed are determined based on the rate of change of the top temperature.

[0059] This setting allows for flexible speed settings, resulting in better overflow prevention.

[0060] For example, the target cooking function is a porridge cooking function. The target cooking function is executed based on the execution instruction, including: heating with a first power when the top temperature is less than a third temperature threshold until the top temperature reaches the third temperature threshold, and the third temperature threshold is less than the first temperature threshold; and heating with a second power after the top temperature reaches the third temperature threshold until the top temperature reaches the second temperature threshold; wherein the first power is greater than the second power.

[0061] According to the above technical solution, during the porridge-cooking process, different power levels can be used to heat the food at different top temperatures. This ensures cooking quality. Furthermore, by setting the first power to be greater than the second power, the heating power of the heating device can be gradually reduced as the top temperature rises, thus guaranteeing the optimal cooking effect.

[0062] For example, executing the target cooking function based on the execution instruction further includes: heating with a third power after the top temperature reaches a second temperature threshold until the entire cooking time of the target cooking function is over; wherein the second power is greater than the third power.

[0063] This design allows for different power levels to be used for heating at different top temperatures during the porridge-cooking process. This ensures cooking quality. Furthermore, setting the second power to be greater than the third power allows for a gradual reduction in the heating power as the top temperature rises, thus maintaining optimal food cooking results.

[0064] For example, the target cooking function is a rice cooking function, and the cooking appliance also includes a bottom temperature sensor for detecting the temperature of the inner pot of the cooking appliance. The above-mentioned shaking operation is performed during at least one cooking period in the execution of the target cooking function, and further includes: when the bottom temperature is within a preset range around a fourth temperature threshold, a third shaking operation is performed until the preset water absorption time ends, and the lifting operation in the third shaking operation has a third execution speed.

[0065] According to the above technical solution, a bottom temperature sensor installed in the cooking appliance can detect the bottom temperature, and then determine whether to perform a third shaking operation based on the bottom temperature value. This method can automatically perform a shaking operation when the rice cooking function reaches the water absorption stage, ensuring that the upper and lower layers of rice absorb water to the same degree, which greatly improves subsequent overflow prevention and cooking effect.

[0066] For example, executing the target cooking function based on the execution instruction further includes: heating with a fourth power when the bottom temperature is less than a fourth temperature threshold until the bottom temperature reaches the fourth temperature threshold; heating with a fifth power after the bottom temperature reaches the fourth temperature threshold to maintain the bottom temperature within a preset range around the fourth temperature threshold until the preset water absorption time ends; heating with a sixth power after the preset water absorption time ends until the top temperature reaches a second temperature threshold; and heating with a seventh power after the top temperature reaches the second temperature threshold until the entire cooking time of the target cooking function ends.

[0067] According to the above technical solution, by detecting the bottom temperature and the top temperature, the corresponding power is used for heating when the temperature is at different stages, which can achieve better cooking results and improve the user experience.

[0068] For example, each lifting mechanism includes a motor, and after receiving an execution command for any target cooking function and before executing the target cooking function based on the execution command, the method further includes: controlling at least some of the lifting mechanisms to simultaneously rise to a maximum height; detecting the load current of the motors in at least some of the lifting mechanisms during operation; determining the amount of food in the inner pot based on the load current; and determining the heating power of each heating operation and / or the execution speed of the lifting operation in each shaking operation during the execution of the target cooking function based on the amount of food.

[0069] According to the above technical solution, the amount of food in the inner pot is determined based on the motor's load current, which in turn determines the heating power and / or the lifting speed of each shaking operation during the execution of the target cooking function. Therefore, different amounts of food can be cooked with matched heating power or shaking speed to achieve better cooking results.

[0070] For example, the larger the amount of food, the greater the heating power during the execution of the target cooking function, and / or the smaller the execution speed of the lifting operation in the same shaking operation during the execution of the target cooking function.

[0071] According to the above technical solution, the heating power and / or the lifting speed during the same shaking operation can be adjusted based on the amount of food consumed. This can meet the cooking needs of different cooking functions, thereby achieving better cooking results.

[0072] For example, for any cooking period, a preset time interval is between every two adjacent height change operations in the corresponding shaking operation.

[0073] According to the above technical solution, compared with the continuous shaking solution, the intermittent shaking solution can save power consumption to a certain extent.

[0074] According to a fourth aspect of the present invention, an electronic device is also provided, comprising a processor and a memory, wherein the memory stores computer program instructions, which, when executed by the processor, are used to perform the above-described control method for multiple lifting structures in a cooking appliance or the above-described cooking control method for a cooking appliance.

[0075] According to the above technical solution, the swaying operation is achieved by controlling multiple lifting mechanisms to sequentially perform height change operations. The height change operation in this solution mainly relies on the cyclic execution of lifting operations; the control logic is relatively simple and easy to implement, thus resulting in low cost.

[0076] According to a fifth aspect of the invention, a storage medium is also provided, on which program instructions are stored, which, when executed, are used to perform the control method for multiple lifting structures in a cooking appliance described above or the cooking control method for a cooking appliance described above.

[0092] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0093] The inventors analyzed the root cause of overflow when cooking porridge in a rice cooker with a heating plate and discovered that uneven water temperature easily leads to overflow. Analysis revealed that when the top temperature sensor detects the boiling point, excessive heat accumulates at the bottom. Even if the heating plate stops heating, residual heat continues to rise, causing bubbles to rise. These bubbles, coated with rice water, become difficult to break and accumulate on the surface, ultimately leading to overflow. If a method could be used to quickly and evenly distribute the temperature inside the pot, overflow could be prevented at its source. Tests showed that shaking the inner pot while cooking porridge rapidly reduces the number of bubbles. Therefore, this invention employs a lifting mechanism located below the inner pot to shake it, achieving temperature balance and preventing overflow.

[0094] To at least partially solve the above-mentioned technical problems, embodiments of the present invention provide a cooking appliance that may include a pot body. The pot body may include an inner pot and multiple lifting mechanisms. The number of lifting mechanisms may be greater than or equal to two. Figure 1 A schematic diagram illustrating the arrangement of multiple lifting mechanisms according to an embodiment of the present invention is shown, such as... Figure 1 As shown, the multiple lifting mechanisms may include lifting mechanisms 100a, 100b and 100c. Figure 1 The arrangement of the lifting mechanisms shown is just an example; the number and arrangement of the lifting mechanisms can be changed.

[0095] For example, the inner pot can be supported on multiple lifting mechanisms; the multiple lifting mechanisms can be used to form multiple combinations of height changes during the execution of the target cooking function, so that the inner pot shakes during the execution of the target cooking function, wherein each of the multiple lifting mechanisms has a corresponding rising height in each combination of heights formed.

[0096] In one embodiment, the cooking appliance can be used to perform multiple cooking functions, such as cooking rice, porridge, soup, and reheating food. The cooking function selected by the user during the operation of the cooking appliance can be considered the target cooking function of the appliance. Exemplarily, and not limitingly, the cooking appliance may include a pot body, a lid, a power board, a display panel, etc. The pot body may include an inner pot, multiple lifting mechanisms, etc. The pot body may have a cylindrical inner pot storage section, in which the inner pot is placed. The inner pot has a cavity with an open upper end, in which food can be placed for heating. The lifting mechanisms can be any structure capable of performing lifting functions. The lifting mechanisms 100a, 100b, and 100c can be arranged in any configuration. Exemplarily, such as... Figure 1 As shown, three lifting mechanisms are evenly distributed in a triangular shape. The inner pot can be supported on these three lifting mechanisms. By setting each of the three lifting mechanisms to a certain lifting height, a height combination can be formed. During the execution of the target cooking function, multiple alternating height combinations can be formed. An alternating height combination means that in every two adjacent height combinations, the lifting heights of multiple lifting mechanisms are not completely fixed, that is, the lifting height of at least one lifting mechanism will change. Based on the alternating height combinations formed by the three lifting mechanisms, the inner pot supported on them can sway during the execution of the target cooking function. Through swaying, the water temperature in the pot can become more uniform, and the temperature at the top and bottom will reach equilibrium more quickly, so that the top temperature sensor in the cooking appliance can more accurately detect the water temperature in the pot. Therefore, when the temperature detected by the top temperature sensor indicates that the food has reached the preset temperature (e.g., the preset boiling temperature) and the heating device is stopped, the residual heat at the bottom of the pot will be less, and the heating inertia in the top cooking space will be greatly reduced, thus indirectly achieving an anti-overflow effect.

[0097] In another embodiment, Figure 2 A schematic diagram illustrating the arrangement of multiple lifting mechanisms according to another embodiment of the present invention is shown, such as... Figure 2 As shown, the number of lifting mechanisms can be four. Similarly, lifting mechanisms 200a, 200b, 200c, and 200d can be distributed in any arrangement. For example, the four lifting mechanisms are evenly distributed in a rectangular shape.

[0098] According to embodiments of the present invention, the cooking appliance can utilize multiple lifting mechanisms to create alternating height combinations during the execution of the target cooking function, causing the inner pot to sway and thus helping to prevent boiling over. This solution eliminates the need for a blower, thereby reducing appliance noise to some extent while ensuring anti-overflow effectiveness and without affecting cooking efficiency. This anti-overflow solution effectively improves the user experience.

[0099] For example, the pot body may also include a heating device disposed between the inner pot and a plurality of lifting mechanisms, the inner pot being supported on the plurality of lifting mechanisms by the heating device.

[0100] By way of example, and not limitation, the heating device may include a heating plate. The heating plate may be positioned between the inner pot and multiple lifting mechanisms. The multiple lifting mechanisms are positioned below the heating plate, and the inner pot can be supported on the lifting mechanisms via the heating plate. Thus, the heating device can adequately heat the food in the inner pot. The inner pot being supported on the lifting mechanisms by the heating device prevents spillage while maintaining effective heating of the inner pot.

[0101] For example, any one of the multiple lifting mechanisms may include a motor and a transmission rod, with a cam provided on the output shaft of the motor and the transmission rod provided on the cam.

[0102] In one embodiment, one or all of the multiple lifting mechanisms may each include a motor and a drive rod. The motor may be a stepper motor, a servo motor, etc. A cam of any shape may be mounted on the motor's output shaft. For example, the cam may be any structure with a protruding portion, such as an elliptical or pentagonal cross-section. The cross-section of the cam refers to the section of the cam perpendicular to the motor's output shaft. The drive rod may be mounted on the cam to move up and down following the rotation of the cam during motor rotation.

[0103] Therefore, based on the cam mounted on the motor output shaft, the edge of the cam is at a different distance from the output shaft. By rotating the cam, the different edges cause the distance between the distal end of the transmission rod and the output shaft to change; the distal end refers to the end of the transmission rod furthest from the motor output shaft. Thus, by rotating the cam, the up-and-down reciprocating motion of the transmission rod can be achieved. The cam is simple to implement and inexpensive.

[0104] For example, the pot body may also include a heating device, which is disposed between the inner pot and multiple lifting structures. The inner pot is supported on the multiple lifting mechanisms by the heating device. The transmission rod is fixed on the heating device, and a recess is provided at the end of the transmission rod that contacts the cam. The recess can engage with the protrusion on the cam.

[0105] In one embodiment, the aforementioned transmission rod can be fixed to a heating device (e.g., a heating plate). Figure 3A schematic diagram of a lifting mechanism according to an embodiment of the present invention is shown. A recess 310 may be provided at the end of the transmission rod that contacts the cam. Exemplarily, the cross-section of the recess 310 (the section perpendicular to the output shaft of the motor) may be arc-shaped. The recess 310 of the transmission rod may engage with a protrusion of the cam. For a cam with an elliptical cross-section (which may be called an elliptical cam), its protrusion may be the portion corresponding to any endpoint of the major axis of the ellipse, and the two endpoints may correspond one-to-one with two protrusions. For a cam with a pentagonal cross-section, its protrusion may be the portion corresponding to any one of the five points of the pentagon, and the five points of the pentagon may correspond one-to-one with five protrusions. Figure 3 The cam shown is an elliptical cam. The dashed line indicates the approximate position of the elliptical cam when its major axis is perpendicular to the extension direction of the transmission rod.

[0106] Therefore, the recessed part at the end of the transmission rod that contacts the cam allows the transmission rod and the cam to fit more tightly, preventing the transmission rod from falling off during motor rotation.

[0107] For example, the cooking appliance may also include a lid that is closable on the pot body, forming a cooking space when the lid is fastened to the pot body. The lid includes a removable cover and a top cover, which are connected by a ball joint; and / or, at least one elastic element is provided between the removable cover and the top cover.

[0108] In one embodiment, the cooking appliance may further include a lid. The lid, positioned above the pot body, is an openable and closable cover. When the lid is fastened to the pot body, a cooking space is formed. Furthermore, the lid may include a removable cover and a top cover, the removable cover being connected to the top cover in any manner. Exemplarily, and not limitingly, the removable cover and the top cover may be connected via a ball joint. Exemplarily, one or more elastic elements may also be provided between the removable cover and the top cover. The elastic element may be any elastic mechanism, including but not limited to springs, elastic strips, elastic sleeves (e.g., rubber sleeves), etc. Figure 4 A schematic diagram of a removable cover according to an embodiment of the present invention is shown. Figure 4 As shown, the removable cover can be equipped with three springs 410 and a ball joint 420. The three springs can be positioned at any location on the removable cover. Note that... Figure 4 The spherical connector 420 shown is incomplete, only the mating part is shown. An exemplary structure of the spherical connector is described below. Figure 5 A front view of a spherical connector according to an embodiment of the present invention is shown. Figure 6 and Figure 7 The front view and top view of the spherical connector connection portion according to an embodiment of the present invention are shown respectively. Figure 5As shown, the spherical connector can be divided into a connecting part a and a mating part b. Connecting part a has a spherical protrusion, and mating part b has a spherical cavity. The spherical cavity can fit into the spherical protrusion of connecting part a. Connecting part a can be connected to the top cover, and mating part b can be connected to the removable cover. Thus, the top cover and the removable cover can be connected together using the spherical connector. Of course, the above is just an example; it is also feasible for connecting part a to the removable cover and mating part b to the top cover.

[0109] Therefore, based on the structure of at least one elastic element, the removable lid can fit more snugly against the inner pot.

[0110] To ensure a tight seal and prevent poor sealing between the inner pot and lid during shaking, a spherical connector allows for multi-angle rotation. This reduces resistance when the inner pot shakes and minimizes structural wear after prolonged use.

[0111] Frictional loss between them.

[0112] For example, the spherical connector has a cavity in which a top temperature sensor is disposed for detecting the top temperature in the cooking space.

[0113] In one embodiment, the spherical connector may have a cavity. For example, a cavity may be provided in the connector a shown in FIG. 5, which can be used to house the top temperature sensor.

[0114] The top temperature sensor can be any suitable sensor capable of detecting temperature, including but not limited to thermistor (NTC) sensors. This top temperature sensor can transmit the detected top temperature information of the cooking space to the cooking appliances using wired or wireless transmission methods.

[0115] Controlling devices, such as the main control chip in cooking appliances, can be, for example, a microcontroller unit (MCU).

[0116] Therefore, placing the top temperature sensor within the cavity saves space in the cooking appliance. It also prevents the top temperature sensor from contacting other structures, thus extending its lifespan.

[0117] For example, the cooking appliance also includes a controller for performing a shaking operation to control multiple lifting mechanisms to form multiple combinations of varying heights during the execution of the target cooking function.

[0118] In one embodiment, the cooking appliance may further include a controller. The controller can be any suitable processing device with data processing and / or instruction execution capabilities. For example, the controller can...

[0119] Employing microcontroller units (MCUs), programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), and programmable logic arrays (PLAs), and central...

[0120] This is achieved through one or a combination of processing units (CPU), application-specific integrated circuits (ASICs), and other types of processing units. The controller can control the multiple lifting mechanisms in the preceding embodiments, with each lifting mechanism operating at a different height during the execution of the target cooking function.

[0121] The controller mentioned above can be the main control chip in the cooking appliance, or it can be an independent controller that is different from the main control chip.

[0122] Therefore, the shaking operation can be performed automatically by the controller. This solution is more intelligent and requires no user intervention, thus improving the user experience.

[0123] For example, the swaying operation may include performing at least one height change operation on a plurality of lifting mechanisms, each height change operation may include: controlling at least one group of lifting mechanisms among the plurality of lifting mechanisms to rise to a maximum height, wherein the plurality of lifting mechanisms are divided into multiple groups of lifting mechanisms; and cyclically performing the following lifting operations: controlling at least some groups of lifting mechanisms that have risen to the maximum height to fall to the minimum height, and controlling at least some groups of lifting mechanisms that are currently at the minimum height to rise to the maximum height.

[0124] In one embodiment, multiple lifting mechanisms can be divided into multiple groups of lifting mechanisms. For example... Figure 1 In the illustrated embodiment, the three lifting mechanisms can be divided into three groups, each group containing one lifting mechanism. In another embodiment, as shown... Figure 2 In the illustrated embodiment, there are four lifting mechanisms: lifting mechanism 200a, lifting mechanism 200b, lifting mechanism 200c, and lifting mechanism 200d. Any two adjacent lifting mechanisms can be grouped into one group, and the other two can be grouped into another group. For example, lifting mechanisms 200a and 200b can be grouped into group A, and lifting mechanisms 200c and 200d can be grouped into group B.

[0125] In the height change operation, the controller described in the previous embodiment can first control at least one group of lifting mechanisms to rise to the maximum height. At least one group of lifting mechanisms can rise to the maximum height simultaneously, or sequentially. Subsequently, the multiple groups of lifting mechanisms can cyclically perform the following lifting operations.

[0126] For example, refer to Figure 1Assuming that the lifting mechanism 100a has already risen to its maximum height at the current moment, the controller described in the previous embodiment can control the lifting mechanism 100a to descend to its minimum height, and then control the lifting mechanism currently at its minimum height (e.g., lifting mechanism 100b) to rise to its maximum height. This step is repeated cyclically to achieve the swaying operation. In another embodiment, for example... Figure 2 In the illustrated embodiment, assuming that lifting mechanisms 200a and 200b have reached their maximum height at the current moment, the controller can control either lifting mechanism to descend to its minimum height, or it can control both lifting mechanisms to descend to their minimum height. It can be understood that if the controller controls one lifting mechanism (e.g., lifting mechanism 200a) to descend to its minimum lifting height, then it will control the lifting mechanism currently at its minimum height to rise to its maximum height. Repeating this process can also achieve a swaying operation.

[0127] According to the above technical solution, swaying is achieved by controlling multiple lifting mechanisms to sequentially perform height change operations. The height change operation in this solution mainly relies on the cyclic execution of lifting operations; the control logic is relatively simple and easy to implement, thus resulting in low cost.

[0128] For example, the lifting operation may specifically include: controlling a group of lifting mechanisms adjacent to the first group of lifting mechanisms along a first direction to rise to the maximum height, and controlling a second group of lifting mechanisms to fall to the minimum height. The first group of lifting mechanisms is the group of lifting mechanisms that is at the forefront along the first direction among the lifting mechanisms that have risen to the maximum height, and the second group of lifting mechanisms is the group of lifting mechanisms that is at the rear along the first direction among the lifting mechanisms that have risen to the maximum height.

[0129] The controller described in the preceding embodiment can control a group of lifting mechanisms adjacent to the first group of lifting mechanisms along a first direction to rise to their maximum height, while simultaneously controlling a second group of lifting mechanisms to descend to their minimum height. The first direction can represent any direction, such as clockwise or counterclockwise. The following explanation uses a clockwise direction as an example. (Refer to...) Figure 1The three lifting mechanisms are, in clockwise order, lifting mechanism 100a, lifting mechanism 100b, and lifting mechanism 100c. Exemplarily, the three lifting mechanisms can be controlled to rise and fall according to the following steps: Step S1, control lifting mechanism 100a to rise to its maximum height. Step S2, after lifting mechanism 100a reaches its maximum height, it remains stationary, and the lifting mechanism 100b, which is adjacent to it in the clockwise direction, can be controlled to rise to its maximum height. Step S3, after lifting mechanism 100b also reaches its maximum height, it remains stationary, and the lifting mechanism 100c, which is adjacent to it in the clockwise direction (at this time, it is the first group of lifting mechanisms), can be controlled to rise to its maximum height, while lifting mechanism 100a (at this time, it is the second group of lifting mechanisms) descends to its minimum height. Step S4: After the lifting mechanism 100c rises to its maximum height, it remains stationary. The lifting mechanism 100a, which is adjacent to it in a clockwise direction (at this time, it is the first group of lifting mechanisms), can then be controlled to rise to its maximum height, while the lifting mechanism 100b (at this time, it is the second group of lifting mechanisms) descends. Step S5: After the lifting mechanism 100a rises to its maximum height, it remains stationary. The lifting mechanism 100b, which is adjacent to it in a clockwise direction (at this time, it is the first group of lifting mechanisms), can then be controlled to rise to its maximum height, while the lifting mechanism 100c (at this time, it is the second group of lifting mechanisms) descends. Steps S3 to S5 are repeated to achieve a swaying effect. It can be understood that in the above embodiment, the lifting mechanisms 100a and 100b that rise in steps S1 and S2 are at least one group of lifting mechanisms that initially rise, and steps S3, S4, and S5 are cyclically executed lifting operations. Of course, the above-described height change operation is merely an example and not a limitation of the present invention. These three lifting mechanisms are not limited to the above-described lifting methods.

[0130] In another embodiment, refer to Figure 2The four lifting mechanisms, arranged clockwise, are lifting mechanism 200a, lifting mechanism 200b, lifting mechanism 200c, and lifting mechanism 200d. Exemplarily, the four lifting mechanisms can be controlled to rise and fall according to the following steps: Step S1: Control lifting mechanisms 200a and 200b in group A to rise to their maximum height. Step S2: After group A has reached its maximum height, control lifting mechanisms 200c and 200d in group B (which is now the first group of lifting mechanisms) to rise to their maximum height, and control group A (which is now the second group of lifting mechanisms) to fall. Step S3: After group B has reached its maximum height, control group A (which is now the first group of lifting mechanisms) to rise to its maximum height, and control group A (which is now the second group of lifting mechanisms) to fall. Repeat steps S2 to S3 to achieve a swaying effect. It can be understood that in the above embodiment, the A-group lifting mechanism that rises in step S1 is at least one group of lifting mechanisms that initially rises, and steps S2 and S3 are cyclic lifting operations. Of course, the above-described height change operation is merely an example and not a limitation of the invention; these four lifting mechanisms are not limited to the above lifting method.

[0131] For example, during any lifting operation, the lifting mechanism adjacent to the first lifting mechanism and the lowering mechanism of the second lifting mechanism can be performed simultaneously or sequentially.

[0132] According to the above technical solution, each time, the first set of lifting mechanisms adjacent to the first set of lifting mechanisms (which is located at the forefront along the first direction) is controlled to rise to the maximum height, and the second set of lifting mechanisms (which is located at the rearmost along the first direction) is controlled to descend to the minimum height, thereby achieving height change. This method ensures orderly lifting and lowering, making the shaking of the inner pot more stable and orderly, which helps reduce wear and tear on cooking utensils and provides a better user experience.

[0133] For example, the grouping of multiple lifting mechanisms is different in at least two different height change operations, and / or the execution speed of the lifting operations is different in at least two different height change operations.

[0134] In one embodiment, refer to Figure 2During the first height change operation, the four lifting mechanisms can be divided into two groups. Group A includes lifting mechanisms 200a and 200b, while group B includes 200c and 200d. In subsequent height change operations (e.g., the third height change operation), group A may include lifting mechanisms 200b and 200c, and group B may include lifting mechanisms 200d and 200a. Furthermore, during multiple height change operations, the execution speed of the lifting operations in any two height change operations can be the same or different. For example, during the first height change operation, the lifting operation can be performed once every 1 second, and during the fourth height change operation, it can be performed once every 2 seconds.

[0135] Of course, it is also feasible to keep the grouping method of multiple lifting mechanisms consistent in all height change operations in the swaying operation, and / or to keep the execution speed of the lifting operation consistent in all height change operations in the swaying operation.

[0136] Therefore, during the shaking operation, the method of changing the height can be changed at least once, which can achieve a more varied shaking effect, help to achieve better cooking results and prevent spills, and further improve the user experience.

[0137] For example, the controller can also be used to: receive an execution instruction for any target cooking function; execute the target cooking function based on the execution instruction; wherein the controller is specifically used to perform a shaking operation during at least one cooking period in the execution of the target cooking function.

[0138] In one embodiment, the cooking appliance may further include a control panel. This control panel allows a user to select a target cooking function to be performed. For example, a user selects rice cooking as the target cooking function via the control panel. The controller then receives an execution command for the rice cooking function and begins executing the rice cooking function based on that command. Simultaneously, during the execution of the rice cooking function, a shaking operation is performed within each cooking period (e.g., excluding the keep-warm stage) at least once.

[0139] In the above technical solution, the controller can receive and execute instructions for any target cooking function, and automatically perform the shaking operation during at least one cooking period in the process of executing the target cooking function to achieve the shaking effect. This can improve the intelligence and automation of cooking appliances and enhance their ease of use.

[0140] For example, the cooking appliance may further include a top temperature sensor for detecting the top temperature of the cooking space of the cooking appliance, and the controller is specifically configured to: perform a first shaking operation when the top temperature is greater than a first temperature threshold and less than a second temperature threshold, wherein the lifting operation in the first shaking operation has a first execution speed; and / or perform a second shaking operation when the top temperature is greater than the second temperature threshold, wherein the lifting operation in the second shaking operation has a second execution speed; wherein the first temperature threshold is less than the second temperature threshold, and the difference between the second temperature threshold and a preset top boiling temperature is less than the first temperature difference threshold.

[0141] In one embodiment, the preset top boiling temperature can be set according to the model of the cooking appliance and the cooking function selected by the user. Different models of cooking appliances can have different preset top boiling temperatures for the same cooking function, and the same model of cooking appliance can also have different preset top boiling temperatures for different cooking functions. For example, for the same model of cooking appliance, the preset top boiling temperature for rice cooking and soup cooking functions is generally higher than that for porridge cooking, for example, 5 degrees Celsius higher (hereinafter referred to as "degrees"). After the user selects a specific cooking function for a specific cooking appliance (whose model is obviously fixed at the time of use), the preset top boiling temperature is fixed. Based on the top temperature sensor in the previous embodiment, the top temperature inside the cooking appliance can be detected in real time. The user can preset a first temperature threshold and a second temperature threshold to determine the required shaking operation and its execution speed. The first temperature threshold can represent any temperature value greater than 0, which can be in the range of [65, 75] degrees, such as 67 degrees, 70 degrees, 72 degrees, etc. In one embodiment, the first temperature threshold can be equal to 72 degrees. For example, the preset top boiling temperature can be in the range of [90, 96] degrees, such as 96 degrees. The second temperature threshold can be lower than the preset top boiling temperature; for example, the difference between the second temperature threshold and the preset top boiling temperature can be less than the first temperature difference threshold. The first temperature difference threshold can be any value greater than or equal to 0, and it can be in the range of [0, 5] degrees, such as 2 degrees. For example, if the preset top boiling temperature is 96 degrees, the second temperature threshold could be 94 degrees.

[0142] When the top temperature sensor detects a top temperature greater than a first temperature threshold Ttop1 and less than a second temperature threshold Ttop2, the controller can perform a first shaking operation. During the first shaking operation, the lifting mechanism performs lifting operations at a first execution speed. The first execution speed can be any value greater than 0; for example, performing a lifting operation once per second can be considered an execution speed of 1 Hz. The first execution speed can be set to any suitable value as needed, falling within the range of [0.1, 10] Hz, such as 3 Hz, 2 Hz, 1 Hz, etc. When the top temperature sensor detects a top temperature greater than the second temperature threshold Ttop2, the controller can perform a second shaking operation. The second execution speed can be any value greater than 0. The second execution speed can be set to any suitable value as needed, falling within the range of [0.1, 10] Hz, such as 3 Hz, 2 Hz, 1 Hz, etc. The first and second execution speeds can be the same or different.

[0143] The shaking operations for the first and second shaking operations have been described in detail in the previous embodiments, and will not be repeated here for the sake of brevity.

[0144] According to the above technical solution, when the temperature at the top indicates that the water is close to boiling or has basically reached the boiling state, at least one shaking operation can be performed. This can accelerate the uniformity of the water temperature in the pot before boiling and accelerate the balance of the upper and lower temperatures, thereby helping to better prevent overflow.

[0145] For example, the first execution speed is greater than the second execution speed; and / or, the first execution speed and / or the second execution speed are determined based on the rate of change of the top temperature.

[0146] In one embodiment, the first execution speed can be equal to 2Hz, and the second execution speed can be equal to 1Hz. When the top temperature is greater than the first temperature threshold but less than the second temperature threshold, the liquid in the pot is close to boiling, and the probability of overflow is high. Therefore, a faster lifting and lowering speed can be used to minimize the risk of overflow. Conversely, when the top temperature is greater than the second temperature threshold, the liquid in the pot is essentially boiling, and the probability of overflow is low. Therefore, a lower speed can be used to maintain a good anti-overflow effect while reducing power consumption. This configuration allows for flexible speed settings to achieve a better anti-overflow effect.

[0147] In one embodiment, the first execution speed and / or the second execution speed are determined based on the rate of change of the top temperature. For example, the greater the rate of change of the top temperature, the greater the first execution speed and / or the second execution speed. The rate of change of the top temperature refers to the current rate of change of the top temperature, meaning the first execution speed and / or the second execution speed can be adjusted in real time according to the rate of change of the top temperature. The rate of change of the top temperature, v, can be calculated using the top temperature value T1 corresponding to the first time t1 and the top temperature value T2 corresponding to the second time t2. For example, it can be calculated using the formula v = (T2 - T1) / (t2 - t1). A large rate of change of the top temperature indicates rapid heating, which may quickly approach boiling point. Therefore, the frequency of agitation (i.e., the speed of the lifting and lowering operation) can be optionally increased to allow the temperature to reach equilibrium more quickly. Conversely, the frequency of agitation can be optionally decreased. This scheme, which determines the execution speed of the lifting and lowering operation based on the rate of change of the top temperature, has higher adaptability and better overflow prevention effect.

[0148] For example, the target cooking function is a porridge cooking function, and the controller can be specifically used to: heat with a first power when the top temperature is less than a third temperature threshold until the top temperature reaches the third temperature threshold, and the third temperature threshold is less than the first temperature threshold; after the top temperature reaches the third temperature threshold, heat with a second power until the top temperature reaches the second temperature threshold; wherein, the first power is greater than the second power.

[0149] The third temperature threshold can be any temperature value greater than 0 that needs to be set, and it can be in the range of [55, 70] degrees, such as 60 degrees, 65 degrees, 70 degrees, etc. In one embodiment, the third temperature threshold can be equal to 65 degrees. Figure 8 A schematic flowchart illustrating the execution of a porridge-cooking function according to an embodiment of the present invention is shown. When the target cooking function is porridge cooking, the controller can specifically be used to perform the following operations: When the top temperature detected by the current top temperature sensor is less than a third temperature threshold Ttop3, the heating device can be controlled to heat at a first power. The first power can be any power. Exemplarily, and not limitingly, the first power can represent full power. During the heating process at the first power, when the top temperature reaches the third temperature threshold (i.e., 65 degrees), the controller can control the heating device to heat at a second power. The magnitude of the second power can be set as needed. Exemplarily, and not limitingly, the second power can be less than the first power, for example, equal to 60% to 80% of the full power. For example, the second power can be equal to 70% of the full power.

[0150] See Figure 8When the top temperature reaches the first temperature threshold but not the second temperature threshold, the first shaking operation described above can be performed. After the top temperature reaches the second temperature threshold, the second shaking operation described above can be performed. Both shaking operations can prevent overflow.

[0151] According to the above technical solution, during the porridge-cooking process, different power levels can be used to heat the food at different top temperatures. This ensures cooking quality. Furthermore, by setting the first power to be greater than the second power, the heating power of the heating device can be gradually reduced as the top temperature rises, thus guaranteeing the optimal cooking effect.

[0152] For example, the controller can also be used to: heat with a third power after the top temperature sensor reaches a second temperature threshold until the entire cooking time of the target cooking function is over; wherein the second power is greater than the third power.

[0153] In one embodiment, during heating at a second power, once the top temperature reaches a second temperature threshold (e.g., 94 degrees Celsius), the controller can control the heating device to heat at a third power until the entire cooking time of the porridge function is completed. The magnitude of the third power can be set as needed. Exemplarily, and not limitingly, the third power can be less than the second power, for example, equal to 5% to 15% of the full power. For example, the third power can be equal to 10% of the full power.

[0154] For example, any one or more of the first power, second power, and third power described above can be determined based on the rate of change of the top temperature. For instance, the greater the rate of change of the top temperature, the smaller any one or more of the first power, second power, and third power can be. The rate of change of the top temperature can be understood with reference to the above. In one example, the second power can be determined based on the rate of change of the top temperature; the greater the rate of change of the top temperature, the smaller the second power is set, which can optionally be adjusted within the range of [60% full power, 80% full power].

[0155] This design allows for different power levels to be used for heating at different top temperatures during the porridge-cooking process. This ensures cooking quality. Furthermore, setting the second power to be greater than the third power allows for a gradual reduction in the heating power as the top temperature rises, thus maintaining optimal food cooking results.

[0156] For example, the target cooking function may be a rice cooking function, and the cooking appliance may also include a bottom temperature sensor for detecting the temperature of the inner pot of the cooking appliance. The controller may specifically be used to: perform a third shaking operation until the preset water absorption time ends when the bottom temperature is within a preset range around a fourth temperature threshold, wherein the lifting operation in the third shaking operation has a third execution speed.

[0157] In one embodiment, the cooking appliance may further include a bottom temperature sensor. The bottom temperature sensor may be the same as or different from the top temperature sensor described in the previous embodiment. The bottom temperature sensor is located at the bottom of the cooking appliance, i.e., the side in contact with the inner pot. The bottom temperature sensor can detect the bottom temperature inside the cooking appliance in real time. When the bottom temperature sensor detects that the current bottom temperature is within a preset range around a fourth temperature threshold Tbot1, the controller can control multiple lifting mechanisms to perform a third shaking operation until the preset water absorption time ends. The fourth temperature threshold can represent any temperature value greater than 0, and it can be set as needed. For example, the fourth temperature threshold can be in the range of [50, 65] degrees, such as 58 degrees. The preset range around the fourth temperature threshold can be within a preset temperature difference from the fourth temperature threshold, such as 2 degrees, 5 degrees, etc. In one example, the fourth temperature threshold is 58 degrees, and the preset range around the fourth temperature threshold refers to a temperature range of [56, 60] degrees. In the rice cooking function, the bottom temperature is maintained within the range of [56, 60] degrees to facilitate water absorption. The preset water absorption time can be arbitrary and can be set as needed. For example, the preset water absorption time can be in the range of [10, 30] minutes (min), such as 10 min, 15 min, 20 min, etc.

[0158] Traditional rice cookers heat the water to 58 degrees Celsius at the bottom, while the water temperature in the upper layer is still below 30 degrees Celsius, resulting in a significant difference in water absorption between the rice in the upper and lower layers. However, by adding a shaking feature to the inner pot, the water temperature in both layers can be made consistent, ensuring that the rice absorbs water at the same level. This greatly improves subsequent overflow prevention and cooking results.

[0159] Similarly, the third shaking operation is similar to the first and second shaking operations in the previous embodiments, and will not be described again here for simplicity. The lifting and lowering operation in the third shaking operation has a third execution speed. The third execution speed may be the same as or different from the first and second execution speeds described above.

[0160] The above technical solution can be understood to be implemented during the cooking process, such as cooking rice or reheating rice. For some cooking functions that do not have a water absorption stage, such as cooking porridge or making soup, the third shaking operation is unnecessary.

[0161] According to the above technical solution, a bottom temperature sensor installed in the cooking appliance can detect the bottom temperature, and then determine whether to perform a third shaking operation based on the bottom temperature value. This method can automatically perform a shaking operation when the rice cooking function reaches the water absorption stage, ensuring that the upper and lower layers of rice absorb water to the same degree, which greatly improves subsequent overflow prevention and cooking effect.

[0162] For example, executing the target cooking function based on the execution instruction may further include: heating with a fourth power when the bottom temperature is less than a fourth temperature threshold until the bottom temperature reaches the fourth temperature threshold; heating with a fifth power after the bottom temperature reaches the fourth temperature threshold to maintain the bottom temperature within a preset range around the fourth temperature threshold until the preset water absorption time ends; heating with a sixth power after the preset water absorption time ends until the top temperature reaches a second temperature threshold; and heating with a seventh power after the top temperature reaches the second temperature threshold until the entire cooking time of the target cooking function ends.

[0163] Figure 9 A schematic flowchart illustrating the execution of a rice cooking function according to another embodiment of the present invention is shown. Figure 9 As shown, based on the bottom temperature detected in real time by the bottom temperature sensor, if the bottom temperature is lower than a fourth temperature threshold, the controller can control the heating device to heat at a fourth power. In one embodiment, the fourth power is the same as the second power, equal to 70% of the first heating power. When the bottom temperature reaches the fourth temperature threshold, the controller can control the heating device to heat at a fifth power to maintain the current bottom temperature within a preset range around the fourth temperature threshold until the preset water absorption time ends. The fifth power can be any power. For example, the fifth power can be less than the fourth power, for example, the fifth power can be equal to 40% of the first power. After the preset water absorption time ends, the controller can control the heating device to heat at a sixth power until the top temperature detected by the top temperature sensor reaches the second temperature threshold (e.g., 72 degrees Celsius). After the top temperature reaches the second temperature threshold, heating is performed at a seventh power until the entire cooking time of the rice cooking function ends. The magnitudes of the sixth and seventh powers can also be set as needed. Any two of the first, second, third, fourth, fifth, sixth, and seventh powers described herein can be the same or different. In one example, the sixth power can be equal to the second power mentioned above, for example, equal to 70% of the total power. The seventh power can be equal to the third power mentioned above, for example, equal to 10% of the total power.

[0164] Figure 9The timing of the first, second, and third shaking operations in the rice cooking function can be understood as described above, and will not be repeated here. The function of the second shaking operation in the rice cooking function is slightly different from that in the porridge cooking function. In the rice cooking function, after boiling, the seventh power can be used to maintain the boiling state. During the maintenance of boiling, the second shaking operation is performed to allow the condensate on the lid to flow back into the pot. The second shaking operation can continue until the end of the simmering stage in the rice cooking function. The second shaking operation can optionally be intermittent, that is, each height change operation is performed for about 8-10 seconds, and the next height change operation is performed after an interval of about 30 seconds after each height change operation.

[0165] According to the above technical solution, by detecting the bottom temperature and the top temperature, the corresponding power is used for heating when the temperature is at different stages, which can achieve better cooking results and improve the user experience.

[0166] For example, each lifting mechanism may include a motor, and the controller may be specifically configured to: control at least some of the lifting mechanisms to simultaneously rise to a maximum height after receiving an execution instruction for any target cooking function and before executing the target cooking function based on the execution instruction; detect the load current of the motors in at least some of the lifting mechanisms during operation; determine the amount of food in the inner pot based on the load current; and determine the execution speed of each heating power and / or each lifting operation during the execution of the target cooking function based on the amount of food.

[0167] In one embodiment, after the controller receives an execution command for any target cooking function (e.g., porridge cooking), and before the function begins, it can control all or some of the motors in multiple lifting mechanisms to start simultaneously, so that all or some of the lifting mechanisms rise to their maximum height at the same time. (See also: [link to previous section]) Figure 8 The diagram illustrates the simultaneous activation of the three lifting mechanisms 100a, 100b, and 100c. A current detection device can also be installed in the cooking appliance. This device can be located in the motor's output circuit or drive circuit to detect the load current of the motors in the three lifting mechanisms. The amount of food in the inner pot can be determined by the load current of the motors. The larger the amount of food in the inner pot, the larger the load current of the motor; conversely, the smaller the amount of food in the inner pot, the smaller the load current of the motor. Based on the amount of food, the heating power of each heating operation and / or the speed of each lifting operation in each shaking operation can be determined during the porridge cooking function. Exemplarily, and not limitingly, the larger the amount of food, the higher the heating power can be, and the lower the speed of each lifting operation in each shaking operation can be; otherwise, the opposite is true.

[0168] According to the above technical solution, the amount of food in the inner pot is determined based on the motor's load current, which in turn determines the heating power and / or the lifting speed of each shaking operation during the execution of the target cooking function. Therefore, different amounts of food can be cooked with matched heating power or shaking speed to achieve better cooking results.

[0169] For example, the larger the amount of food, the greater the heating power during the execution of the target cooking function, and / or the smaller the execution speed of the lifting operation in the same shaking operation during the execution of the target cooking function.

[0170] In one embodiment, the amount of food in the inner pot can be determined based on the load current. A larger amount of food results in a higher heating power during the porridge cooking function. For example, the second power corresponding to a larger amount of food is greater than the second power corresponding to a smaller amount of food. A larger amount of food also results in a slower lifting speed during the same shaking operation during the porridge cooking function. For example, the lifting speed during the first shaking operation corresponding to a larger amount of food is less than the lifting speed during the first shaking operation corresponding to a smaller amount of food.

[0171] According to the above technical solution, the heating power and / or the lifting speed during the same shaking operation can be adjusted based on the amount of food consumed. This can meet the cooking needs of different cooking functions, thereby achieving better cooking results.

[0172] Optionally, the first and / or second execution speeds can be adjusted appropriately based on the stroke length of the actually installed lifting mechanism. For example, if the stroke of the lifting mechanism is short, the shaking frequency can be increased, as long as the food is not thrown out from above when adjusted to the maximum food volume. Furthermore, the third execution speed can also be adjusted in a similar manner to the first and second execution speeds.

[0173] For example, for any cooking period, a preset time interval is between every two adjacent height change operations in the corresponding shaking operation.

[0174] In one embodiment, for any cooking period, such as the period during which boiling is maintained during the rice cooking function, a first shaking operation is performed at a first execution speed. A preset time interval can be spaced between every two adjacent height change operations in the first shaking operation. The preset time interval can be any time interval greater than 0; for example, the value range of the preset time interval can be [5s, 5min]. The preset time interval can be longer than the execution duration of each height change operation. The implementation method of this intermittent shaking was described above when describing the second shaking operation in the rice cooking function, and will not be repeated here.

[0175] According to the above technical solution, compared with the continuous shaking solution, the intermittent shaking solution can save power consumption to a certain extent.

[0176] It should be noted that although the above mainly uses the porridge and rice cooking functions as examples to describe how the shaking operation is executed, in cases where cooking functions such as stir-frying and stewing are partially implemented, at least one shaking operation can also be performed during the cooking process to help achieve cooking functions such as stir-frying and stewing.

[0177] According to a second aspect of the present invention, a method for controlling multiple lifting mechanisms in a cooking appliance is also provided. The cooking appliance may include a pot body, which may include an inner pot and multiple lifting mechanisms, the inner pot being supported on the multiple lifting mechanisms. The method may include: performing a shaking operation to control the multiple lifting mechanisms to form multiple back-and-forth height combinations during the execution of a target cooking function, causing the inner pot to shake during the execution of the target cooking function, wherein in each formed height combination, each of the multiple lifting mechanisms has a corresponding rising height.

[0178] For example, the swaying operation includes performing at least one height change operation on a plurality of lifting mechanisms, each height change operation may include: controlling at least one group of lifting mechanisms among the plurality of lifting mechanisms to rise to a maximum height, wherein the plurality of lifting mechanisms are divided into multiple groups of lifting mechanisms; and cyclically performing the following lifting operations: controlling at least some groups of lifting mechanisms that have risen to the maximum height to fall to the minimum height, and controlling at least some groups of lifting mechanisms that are currently at the minimum height to rise to the maximum height.

[0179] For example, the lifting operation may specifically include: controlling a group of lifting mechanisms adjacent to the first group of lifting mechanisms along a first direction to rise to the maximum height, and controlling a second group of lifting mechanisms to fall to the minimum height. The first group of lifting mechanisms is the group of lifting mechanisms that are currently at the front along the first direction among the lifting mechanisms that have risen to the maximum height, and the second group of lifting mechanisms is the group of lifting mechanisms that are currently at the back along the first direction among the lifting mechanisms that have risen to the maximum height.

[0180] For example, the grouping of multiple lifting mechanisms is different in at least two different height change operations, and / or the execution speed of the lifting operations is different in at least two different height change operations.

[0181] Those skilled in the art can understand the implementation and beneficial effects of the cooking control method for cooking utensils by reading the relevant descriptions of the cooking utensil method in the embodiments of this article. For the sake of brevity, these will not be elaborated further here.

[0182] According to a third aspect of the present invention, a cooking control method for a cooking appliance is also provided. The cooking appliance may include a pot body, which may include an inner pot and a plurality of lifting mechanisms, the inner pot being supported on the plurality of lifting mechanisms. Figure 10 A schematic flowchart of a cooking control method 1000 for a cooking appliance according to an embodiment of the present invention is shown, such as... Figure 10 As shown, the method 1000 may include the following steps S1010 and S1020.

[0183] Step S1010: Receive the execution instruction for any target cooking function.

[0184] Step S1020: Execute the target cooking function based on the execution instruction, and perform the above-mentioned shaking operation during at least one cooking period in the execution of the target cooking function.

[0185] Those skilled in the art can understand the implementation and beneficial effects of the cooking control method for the cooking appliance by reading the relevant descriptions of the cooking appliance and the control method for multiple lifting structures in the cooking appliance in the embodiments of this article. For the sake of brevity, they will not be described in detail here.

[0186] For example, the cooking appliance also includes a top temperature sensor for detecting the top temperature of the cooking space of the cooking appliance, and performs the above-mentioned shaking operation during at least one cooking period in the execution of the target cooking function, including: performing a first shaking operation when the top temperature is greater than a first temperature threshold and less than a second temperature threshold, wherein the lifting and lowering operation in the first shaking operation has a first execution speed; and / or performing a second shaking operation when the top temperature is greater than the second temperature threshold, wherein the lifting and lowering operation in the second shaking operation has a second execution speed; wherein the first temperature threshold is less than the second temperature threshold, and the difference between the second temperature threshold and the preset top boiling temperature is less than the first temperature difference threshold.

[0187] For example, the first execution speed is greater than the second execution speed; and / or, the first execution speed and / or the second execution speed are determined based on the rate of change of the top temperature.

[0188] For example, the target cooking function is a porridge cooking function. Executing the target cooking function based on the execution instruction may include: heating with a first power when the top temperature is less than a third temperature threshold until the top temperature reaches the third temperature threshold, which is less than the first temperature threshold; and heating with a second power after the top temperature reaches the third temperature threshold until the top temperature reaches the second temperature threshold; wherein the first power is greater than the second power.

[0189] For example, executing the target cooking function based on the execution instruction may further include: heating with a third power after the top temperature reaches a second temperature threshold until the entire cooking time of the target cooking function is over; wherein the second power is greater than the third power.

[0190] For example, the target cooking function is a rice cooking function, and the cooking appliance may also include a bottom temperature sensor for detecting the temperature of the inner pot of the cooking appliance. The above-mentioned shaking operation is performed during at least one cooking period in the execution of the target cooking function, and may also include: when the bottom temperature is within a preset range around a fourth temperature threshold, a third shaking operation is performed until the preset water absorption time ends, and the lifting operation in the third shaking operation has a third execution speed.

[0191] For example, executing the target cooking function based on the execution instruction may further include: heating with a fourth power when the bottom temperature is less than a fourth temperature threshold until the bottom temperature reaches the fourth temperature threshold; heating with a fifth power after the bottom temperature reaches the fourth temperature threshold to maintain the bottom temperature within a preset range around the fourth temperature threshold until the preset water absorption time ends; heating with a sixth power after the preset water absorption time ends until the top temperature reaches a second temperature threshold; and heating with a seventh power after the top temperature reaches the second temperature threshold until the entire cooking time of the target cooking function ends.

[0192] For example, each lifting mechanism may include a motor. After receiving an execution command for any target cooking function and before executing the target cooking function based on the execution command, the method may further include: controlling at least some of the lifting mechanisms to rise simultaneously to a maximum height; detecting the load current of the motors in at least some of the lifting mechanisms during operation; determining the amount of food in the inner pot based on the load current; and determining the heating power of each heating operation and / or the execution speed of the lifting operation in each shaking operation during the execution of the target cooking function based on the amount of food.

[0193] For example, the larger the amount of food, the greater the heating power during the execution of the target cooking function, and / or the smaller the execution speed of the lifting operation in the same shaking operation during the execution of the target cooking function.

[0194] For example, for any cooking period, a preset time interval is between every two adjacent height change operations in the corresponding shaking operation.

[0195] According to a fourth aspect of the present invention, an electronic device is also provided. Figure 11 A schematic block diagram of an electronic device 1100 according to an embodiment of the present invention is shown, such as Figure 11As shown, the electronic device 1100 may include a processor 1110 and a memory 1120, wherein the memory 1120 stores computer program instructions, which are executed by the processor 1110 to perform the above-described control method for multiple lifting structures in a cooking appliance or the above-described cooking control method for a cooking appliance.
