Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a cooking appliance, control method, control device and storage medium. Background Technology

[0002] Electric pressure cookers are a common kitchen appliance. They work by vaporizing the liquid inside the pot, which increases the pressure and delays the boiling time of the liquid, thus speeding up the cooking of the food.

[0003] However, when the ingredients in the pot are not piled up evenly or different parts of the ingredients are heated unevenly, traditional electric pressure cookers will result in uneven cooking of the ingredients, which will affect the cooking effect and taste of the ingredients. Summary of the Invention

[0004] Therefore, the purpose of this application is to provide a cooking appliance, a control method, a control device, and a storage medium to solve at least one of the above-mentioned technical problems. The technical solution is as follows:

[0005] On one hand, this application provides a cooking utensil, including:

[0006] A cooking body, wherein the cooking body is provided with a cooking cavity;

[0007] A disturbance structure is disposed within the cooking cavity;

[0008] A driving component, connected to the disturbance structure, is used to drive the disturbance structure to oscillate within the cooking cavity to adjust the distribution of cooking pressure within the cooking cavity.

[0009] In some embodiments, the perturbation structure includes:

[0010] A disturbance plate, the disturbance plate being housed at the bottom of the cooking cavity, the shape of the disturbance plate matching the cross-sectional shape of the cooking cavity; and / or

[0011] A heating unit, disposed within the agitator, is used to provide a heat source for the object contained within the cooking cavity.

[0012] In some embodiments, the driving component includes:

[0013] A motor component, wherein the motor component is disposed outside the cooking cavity;

[0014] A transmission component, one end of which is connected to the disturbance structure, and the other end of which passes through the cavity wall of the cooking cavity and is connected to the motor component;

[0015] A controller, connected to the motor component, is used to control the operation of the motor component according to the condition of the object contained in the cooking cavity.

[0016] In some embodiments, the transmission element includes a telescopic rod;

[0017] When the telescopic rod is in the retracted state, the telescopic rod and the disturbance structure can be housed together in the cooking cavity; when the telescopic rod is in the extended state, the telescopic rod passes through a through hole in the cavity wall of the cooking cavity and is detachably connected to the motor component.

[0018] In some embodiments, the cooking appliance further includes:

[0019] The monitoring component includes at least two monitoring units, which are separately disposed on the cover of the cooking body. Each monitoring unit is used to monitor the cooking pressure and / or cooking temperature at different locations within the cooking cavity.

[0020] In some embodiments, the cooking appliance further includes:

[0021] A liquid level detection device is disposed on the cooking body and is used to detect the position of the oscillating liquid surface of the cooking liquid in the cooking cavity.

[0022] On the other hand, this application also provides a control method applied to any of the cooking appliances described above, the control method comprising:

[0023] When the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the drive component is controlled to operate so as to drive the disturbance structure to swing through the drive component, thereby adjusting the distribution of cooking pressure in the cooking cavity;

[0024] If the parameter difference within the cooking cavity is detected to meet the preset parameter difference, the drive component is controlled to stop working, and the swing position of the disturbance structure is kept unchanged.

[0025] In some embodiments, the drive assembly includes a motor component and a transmission component connected to the motor component;

[0026] The step of controlling the drive component to operate when the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition includes:

[0027] When the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the motor in the motor component is controlled to rotate in the first direction for a first duration and in the second direction for a second duration, so as to drive the disturbance structure to swing through the transmission component; the first direction is opposite to the second direction;

[0028] If the position of the oscillating liquid surface in the cooking chamber is detected to be higher than a preset position threshold, the rotational speed of the motor in the motor component is reduced.

[0029] During the cooking process, if the parameter difference in the cooking cavity is detected to be inconsistent with the preset parameter difference, the motor in the motor component is controlled to continue working.

[0030] In some embodiments, the parameter difference includes a temperature difference and / or a pressure difference, and correspondingly, the preset parameter difference includes a preset temperature difference threshold and / or a preset pressure difference threshold.

[0031] Before controlling the drive component to stop working and maintaining the swing position of the disturbance structure unchanged when the parameter difference within the cooking cavity is detected to meet a preset parameter difference, the method further includes:

[0032] Monitor the first temperature at a first position and the second temperature at a second position within the cooking cavity; the initial temperature at the first position is lower than the initial temperature at the second position.

[0033] Calculate the temperature difference between the first temperature and the second temperature;

[0034] If the temperature difference is less than or equal to a preset temperature difference threshold, the parameter difference within the cooking cavity is determined to satisfy the preset parameter difference.

[0035] Alternatively, monitor the first pressure at a first position and the second pressure at a second position within the cooking cavity; the initial pressure at the first position is less than the initial pressure at the second position.

[0036] Calculate the pressure difference between the first pressure and the second pressure;

[0037] If the pressure difference is less than or equal to a preset pressure difference threshold, the parameter difference within the cooking cavity is determined to satisfy the preset parameter difference.

[0038] On the other hand, this application also provides a control device for a cooking appliance, the control device for the cooking appliance including a processor and a memory, the memory storing at least one instruction or at least one program, the at least one instruction or at least one program being loaded and executed by the processor to implement the control method as described above.

[0039] On the other hand, this application also provides a computer-readable storage medium storing at least one instruction or at least one program, which is loaded and executed by a processor to implement the control method as described above.

[0040] This application provides a cooking appliance, control method, control device, and storage medium. The cooking appliance includes: a cooking body with a cooking cavity; a disturbance structure disposed within the cooking cavity; and a drive assembly connected to the disturbance structure for driving the disturbance structure to oscillate within the cooking cavity, thereby adjusting the distribution of cooking pressure within the cooking cavity. Thus, by adding a disturbance structure to the cooking appliance, the distribution of cooking pressure within the cooking cavity is adjusted through the cooperation of the disturbance structure, the cooking cavity, and the drive assembly. This transforms the uniformly distributed cooking pressure within the cooking cavity into a dynamic high pressure within the pot. Consequently, when food is unevenly piled or heated unevenly in different parts of the food, the dynamic high pressure within the pot adapts to the different heat requirements of the food in different locations, thereby improving the cooking doneness and uniformity of the cooked state, as well as enhancing the cooking effect and taste.

[0041] Furthermore, this application provides a dynamic high-pressure solution within the pot of an embedded pressure cooking appliance, which differs from traditional static high-pressure systems. Moreover, the power source (water-driven) for dynamic high pressure differs from the airflow driven by a fan (air-driven) in traditional steam ovens. Additionally, during cooking, the cooking liquid is adaptively agitated via a disturbance structure, with the optimal agitation level controlled by combining liquid level height and temperature / pressure. This application solves the problem of uneven food distribution within the pot leading to poor localized cooking results, as well as the inability to simultaneously achieve good cooking results for different parts of the food (when steaming), and the problem of suboptimal cooking results for parts of the food above and below the liquid level, thereby improving cooking efficiency and enhancing the level of intelligent cooking.

[0042] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0051] As used herein, “an embodiment” or “an embodiment” refers to a specific feature, structure or characteristic that may be included in at least one implementation of this application.

[0052] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0053] The following describes in detail, with reference to the accompanying drawings, a cooking appliance, control method, control device, and storage medium involved in the embodiments of this application.

[0054] Figure 1 This is a structural cross-sectional view of a cooking utensil provided in an embodiment of this application. Figure 2 This is an exploded view of the structure of a cooking utensil provided in an embodiment of this application. Please refer to... Figure 1 and Figure 2The cooking appliance 100 may include a cooking body 110, a disturbance structure 120, and a drive assembly 130. For example, the cooking appliance may include, but is not limited to, an electric pressure cooker, a pressure cooker, etc.

[0055] The cooking body 110 may include a pot body 112 and a lid 111. The cooking body forms a cooking cavity through the pot body 112 and lid 111, which is used to contain ingredients such as food and liquids (e.g., water). A disturbance structure 120 is disposed within the cooking cavity to agitate the ingredients within the cooking cavity. A drive assembly 130 is connected to the disturbance structure 120 and is used to drive the disturbance structure 120 to oscillate within the cooking cavity to adjust the distribution of cooking pressure within the cooking cavity.

[0056] This application adds a disturbance structure 120 to the cooking appliance. Based on the cooperation of the disturbance structure 120 with the cooking cavity and the drive component 130, the distribution of cooking pressure within the cooking cavity is adjusted. This transforms the cooking pressure from a uniform distribution to a dynamic high pressure within the pot, rather than a stable static high pressure. Therefore, even when food is unevenly packed or heated in different parts of the food, the dynamic high pressure adapts to the varying heat requirements of the food in different locations, thereby improving the uniformity and quality of the cooked food, and enhancing the overall cooking effect and taste.

[0057] In some embodiments, the disturbance structure 120 may include a disturbance plate 121. During cooking, the disturbance plate 121 is housed at the bottom of the cooking cavity, for example, the disturbance plate 121 is positioned near the bottom of the cooking cavity.

[0058] In practical applications, the size of the agitator 121 is smaller than the internal size of the pot body 112 in the cooking body, and the gap between the agitator 121 and the inner wall of the pot body 112 is greater than the interval distance, so that the agitator 121 does not fit against the inner wall of the pot body 112. For example, the interval distance can be any value from 10mm to 30mm.

[0059] Optionally, the shape of the agitator 121 can be, but is not limited to, a disc, a square, an ellipse, or a polygon. Preferably, the shape of the agitator 121 matches the cross-sectional shape of the cooking cavity. For example, if the cross-sectional shape of the bottom of the cooking cavity is circular, then the shape of the agitator 121 is disc-shaped; if the cross-sectional shape of the bottom of the cooking cavity is square, then the shape of the agitator 121 is square, so that the shape of the agitator 121 matches the cross-sectional shape of the bottom surface of the cooking cavity. In this way, by setting the shape of the agitator 121 to match the cross-sectional shape of the cooking cavity, the agitation effect of the agitator 121 is improved to a certain extent, which facilitates faster adjustment of the cooking pressure distribution within the cooking cavity.

[0060] In other embodiments, the disturbance structure 120 may include a disturbance disk 121 and a heating unit 122. The disturbance disk 121 is housed at the bottom of the cooking cavity, and its shape matches the cross-sectional shape of the cooking cavity. The shape of the disturbance disk 121 may be, but is not limited to, a disc shape, a square shape, an ellipse shape, a polygon shape, etc. Preferably, the shape of the disturbance disk 121 matches the cross-sectional shape of the cooking cavity. The heating unit 122 is disposed within the disturbance disk 121 and is used to provide a heat source for the object contained in the cooking cavity. Exemplarily, the heating unit 122 may be a wireless heating mechanism, such as, but not limited to, a wireless heating wire, a wireless heating plate, etc. The heating unit 122 may be embedded inside the cooking cavity and not exposed. Thus, by adding the heating unit 122 to the disturbance disk 121, the heating unit 122 provides an additional auxiliary heat source for the object contained in the cooking cavity, thereby improving cooking efficiency.

[0061] Figure 3 This is a diagram showing the state of the pot inside a cooking appliance before agitation, using a stirring plate 121 in an embodiment of this application. See also... Figure 3 Before the disturbance by the disturbance plate 121, the entire pressure field inside the pot was balanced and stable, and the overall airflow pattern could be divided into two large air masses that were in balance with each other, such as... Figure 3 The left air mass 330 and the right air mass 340 shown in the diagram flow from bottom to top, from the liquid surface 310 ( Figure 3 The wavy lines (as shown in the diagram) flow towards the lid, with the left and right circulation directions being opposite. At the same time, the liquid level 310 in the pot is basically evenly distributed above it, and the liquid level 310 is basically horizontal. Even when the water is boiling, the liquid level 310 and the food 320 are basically horizontal, presenting a horizontal state.

[0062] Figure 4 This is a diagram showing the state of the inside of a pot after agitation using a stirring plate 121 in a cooking appliance according to an embodiment of this application. See also... Figure 4 After the disturbance by the disturbance plate 121, the entire pressure field inside the pot becomes unstable, and the overall airflow pattern can be divided into two unbalanced air masses, such as... Figure 4 The small air mass 410 on the left and the large air mass 420 on the right shown in the diagram flow from bottom to top, from the liquid surface 310 to the lid, with the left and right circulation directions being opposite. At the same time, due to the effect of the disturbance plate 121, the air pressure distribution above the liquid surface 310 in the pot is uneven, and the liquid surface 310 is not horizontal, presenting a state where it is lower on the left and higher on the right.

[0063] In some embodiments, the drive assembly 130 may include a motor component 131, a transmission component 132, and a controller 133.

[0064] The motor component 131 is disposed outside the cooking cavity. Optionally, the motor component 131 may include a motor bracket 1312 and a motor 1311 mounted on the motor bracket 1312, which may be disposed on the cooking appliance. The upper portion of the motor bracket 1312 may have a groove, in which the motor can be at least partially accommodated.

[0065] One end of the transmission member 132 is connected to the disturbance structure 120, and the other end passes through the cavity wall of the cooking cavity and is connected to the motor component 131. Optionally, one end of the transmission member 132 connected to the disturbance structure 120, and the other end of the transmission member 132 passing through the cavity wall of the cooking cavity, can be detachably connected to the motor 1311 in the motor component 131. Exemplary detachable connections include, but are not limited to, snap-fit ​​connections, wedge-shaped fixing connections, threaded connections, screw connections, etc. Specifically, one end of the transmission member 132 can be connected to the disturbance disk 121 in the disturbance structure 120, and the other end passing through the cavity wall of the cooking cavity can be fixedly connected to the motor in the motor component 131 via a wedge-shaped member 134.

[0066] The controller 133 is connected to the motor component 131 and is used to control the operation of the motor component 131 according to the condition of the object contained in the cooking cavity. Optionally, the controller 133 and the motor component 131 can be connected via wired or wireless means. The controller 133 controls the motor 1311 in the motor component 131 to operate by acquiring the condition of the object contained in the cooking cavity, for example by detecting at least one of the temperature, pressure, water level, etc. at various locations in the cooking cavity. The operation of the motor component 131 drives the transmission component 132 connected to it to perform, for example, rotational movement, thereby causing the disturbance structure 120 connected to the transmission component 132 to agitate in the cooking cavity.

[0067] In the above embodiment, the drive assembly 130, consisting of a motor component 131, a transmission component 132, and a controller 133, can automatically control the operation of the motor component 131 according to the condition of the objects contained in the cooking cavity. This facilitates adaptive cooking based on the quantity distribution and doneness of the food in the pot, thereby improving cooking intelligence and efficiency.

[0068] In some embodiments, the transmission member 132 may include a telescopic rod. When the telescopic rod is in the retracted state, it and the disturbance structure 120 can be housed together within the cooking cavity. When the telescopic rod is in the extended state, it passes through a through-hole in the wall of the cooking cavity and is detachably connected to the motor component 131. The extended and retracted telescopic rod and the disturbance structure 120 can be placed as a whole within the cooking cavity, and the placed telescopic rod can pass through the through-hole in the wall of the cooking cavity and be wedge-shaped fixedly connected to the motor component 131.

[0069] In some embodiments, the transmission member 132 may include a transmission rod. Optionally, both ends of the transmission rod may be detachably connected to the motor 1311 in the motor assembly and the disturbance structure 120, respectively. Alternatively, one end of the transmission rod may be fixedly connected to the motor 1311 in the motor assembly; the other end may pass through a through hole in the cavity wall of the cooking cavity and be detachably connected to the disturbance structure 120.

[0070] In some embodiments, the cooking appliance also includes a monitoring component. The monitoring component includes at least two monitoring units 140, which are separately disposed on the cover 111 of the cooking body. Each monitoring unit 140 is used to monitor cooking pressure and / or cooking temperature at different locations within the cooking cavity. Exemplarily, the monitoring unit 140 can be a pressure sensor, a temperature sensor, or a sensor that combines pressure and temperature monitoring functions.

[0071] Optionally, the monitoring component includes at least two pressure sensors, each separately disposed on the cover 111 of the cooking body. For example, one pressure sensor is disposed on the left side of the cover 111 of the cooking body to monitor the cooking pressure at the left position inside the cooking cavity; the other pressure sensor is disposed on the right side of the cover 111 of the cooking body to monitor the cooking pressure at the right position inside the cooking cavity.

[0072] Alternatively, the monitoring component includes at least two temperature sensors, each of which is separately disposed on the cover 111 of the cooking body. For example, one temperature sensor is disposed on the left side of the cover 111 of the cooking body to monitor the cooking temperature at the left side of the cooking cavity; the other temperature sensor is disposed on the right side of the cover 111 of the cooking body to monitor the cooking temperature at the right side of the cooking cavity.

[0073] Alternatively, the monitoring component includes at least two sensors that integrate temperature and pressure detection. Each sensor is separately disposed on the cover 111 of the cooking body. For example, one sensor is disposed on the left side of the cover 111 of the cooking body to monitor the cooking temperature and cooking pressure at the left position inside the cooking cavity; the other sensor is disposed on the right side of the cover 111 of the cooking body to monitor the cooking temperature and cooking pressure at the right position inside the cooking cavity.

[0074] It should be noted that the number n of the monitoring units 140 included in the monitoring component is not limited to two; n can be a value greater than 2, such as 3 or 4. When there are multiple n, the n monitoring units 140 can be evenly distributed and arranged in the cover 111 of the cooking body to monitor the cooking pressure and / or cooking temperature at different locations within the cooking cavity, as monitored by each monitoring unit 140.

[0075] In some embodiments, the cooking appliance also includes a liquid level detection element 150. The liquid level detection element 150 is disposed on the cooking body and is used to detect the position of the oscillating liquid surface of the cooking liquid within the cooking cavity. Exemplarily, the liquid level detection element 150 can be a liquid level sensor, such as a Bluetooth-enabled liquid level sensor. The liquid level detection element 150 can be disposed on the cover 111 of the cooking body. The number of liquid level sensors can be one or more. Specifically, the cooking body also includes a steaming rack 160 for placing and steaming food. During cooking, the steaming rack 160 is disposed above the disturbance structure 120 and in the upper half of the cooking cavity. In this case, the number of liquid level sensors is preferably two, and the two liquid level sensors can be respectively disposed on the left and right sides of the steaming rack 160 to detect the position of the oscillating liquid surface of the cooking liquid at different locations within the cooking cavity.

[0076] In the above embodiment, the cooking liquid in the pot is disturbed by the disturbance structure 120, and combined with the liquid level detection elements 150 on the left and right sides and the temperature (pressure) sensor, adaptive judgment is made on the food in different positions and the degree of cooking in different positions, so as to further improve the intelligence and efficiency of cooking.

[0077] In some embodiments, the cooking appliance also includes an external heating plate 170. The external heating plate 170 may be attached to the outer wall of the pot body 112 in the cooking body and is used to provide a primary heat source for the object contained in the cooking cavity.

[0078] In some embodiments, the cooking appliance further includes functional components and a function controller 133. The function controller 133 is connected to the functional components and is used to control the functional components to perform various cooking functions of the cooking appliance. These include, but are not limited to, atmospheric pressure heating, heating at multiple cooking pressures, and heat preservation functions. The functional components and the function controller 133 may be located at at least one position on the bottom, side wall, or top of the cooking appliance.

[0079] Furthermore, this application provides a dynamic high-pressure solution within the pot of an embedded pressure cooking appliance, which differs from traditional static high-pressure systems. Moreover, the power source (water-driven) for dynamic high pressure differs from the fan-driven airflow of traditional steam ovens. Additionally, during cooking, the cooking liquid is adaptively agitated via a disturbance structure 120, with the optimal agitation level controlled by combining liquid level height and temperature / pressure. This application solves the problem of uneven food distribution within the pot leading to poor localized cooking results, as well as the inability to simultaneously achieve good cooking results for different parts of the food (when steaming), and the problem of suboptimal cooking results for parts of the food above and below the liquid level, thereby improving cooking efficiency and enhancing the level of intelligent cooking.

[0080] Figure 5This is a flowchart of a control method provided in an embodiment of this application. The method can be implemented by software and / or hardware, and is applicable to any of the cooking appliances described above. Please refer to [link / reference]. Figure 5 Taking the control method executed by controller 133 as an example, it may include:

[0081] S501, when the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the drive assembly 130 is controlled to work so as to drive the disturbance structure 120 to swing through the drive assembly 130 to adjust the distribution of cooking pressure in the cooking cavity.

[0082] The disturbance triggering condition refers to the condition that triggers the oscillation of the disturbance structure 120. For example, the disturbance triggering condition may include, but is not limited to, when the temperature sensor detects that the temperature inside the cooking chamber reaches 100°C, or when the pressure sensor detects that the pressure inside the cooking chamber is greater than the standard atmospheric pressure.

[0083] Optionally, when the temperature inside the cooking cavity of the cooking appliance reaches 100°C, or the pressure inside the cooking cavity exceeds the standard atmospheric pressure, it is determined that the cooking cavity of the cooking appliance meets the disturbance triggering condition. At this time, the controller controls the motor 1311 in the drive assembly 130 to operate, and the motor 1311 in the drive assembly 130 drives the transmission component 132 to rotate, thereby causing the disturbance structure 120 to swing, so as to adjust the distribution of cooking pressure inside the cooking cavity.

[0084] In some embodiments, the drive assembly 130 includes a motor component 131 and a transmission member 132 connected to the motor component 131. Step S501 above, controlling the drive assembly 130 to operate when the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, includes:

[0085] When the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the motor 1311 in the control motor component 131 is rotated in the first direction for a first duration and in the second direction for a second duration, so as to drive the disturbance structure 120 to swing through the transmission component 132; the first direction is opposite to the second direction.

[0086] If the position of the oscillating liquid surface in the cooking chamber is detected to be higher than a preset position threshold, the speed of the motor in the motor component 131 is reduced.

[0087] During the cooking process, if the parameter difference in the cooking cavity is detected to be inconsistent with the preset parameter difference, the motor in the motor component 131 is controlled to continue to work.

[0088] Optionally, when the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the motor in the control motor component 131 first rotates in the first direction for a first duration, and then rotates in the second direction for a second duration, so as to drive the disturbance structure 120 to swing in different directions through the transmission component 132. The first direction and the second direction are opposite, for example, the first direction is the forward rotation direction and the second direction is the reverse rotation direction; or the first direction is the reverse rotation direction and the second direction is the forward rotation direction. Optionally, the first duration and the second duration can be any value from 2 seconds to 10 seconds, such as 3 seconds, 4 seconds, 5 seconds, etc.

[0089] Specifically, when the cooking cavity in the cooking appliance is detected to meet the disturbance triggering condition, the controller controls the motor in the motor component 131 to rotate clockwise for 3 seconds and then counterclockwise for 3 seconds, so as to drive the disturbance structure 120 to swing clockwise and counterclockwise through the transmission component 132. The rotational speed of the motor in the clockwise and counterclockwise directions can be any value between 10 r / min and 60 r / min.

[0090] If the liquid level detector 150 detects the oscillating liquid level signal of the cooking liquid in the cooking cavity, and determines that the oscillating liquid level position of the cooking liquid in the cooking cavity is higher than a preset position threshold, this indicates that the motor speed is too high and the cooking liquid (e.g., water) in the cooking cavity is violently disturbed. At this time, the speed of the motor in the motor component 131 is reduced to reduce the oscillation amplitude of the disturbance structure 120, thereby mitigating the disturbance amplitude of the liquid in the cooking cavity. Once the oscillating liquid level position of the cooking liquid is determined to be less than or equal to the preset position threshold, the speed of the motor in the motor component 131 is stopped from being reduced, and the current speed of the motor is maintained to continue working.

[0091] During cooking, the parameter difference within the cooking cavity is detected. If the parameter difference within the cooking cavity does not meet a preset parameter difference value, the controller controls the motor in motor component 131 to continue operating. The parameter difference may include a temperature difference and / or a pressure difference, and correspondingly, the preset parameter difference includes a preset temperature difference threshold and / or a preset pressure difference threshold. Optionally, if the detected temperature difference within the cooking cavity does not meet a preset temperature difference threshold, the controller controls the motor in motor component 131 to continue operating. Alternatively, if the detected pressure difference within the cooking cavity does not meet a preset pressure threshold, the controller controls the motor in motor component 131 to continue operating. Or, if the detected temperature difference within the cooking cavity does not meet a preset temperature difference threshold and the detected pressure difference does not meet a preset pressure threshold, the controller controls the motor in motor component 131 to continue operating.

[0092] It should be noted that during the continuous operation of the motor in the motor component 131, the liquid level detection component 150 continuously detects the oscillating liquid surface signal of the cooking liquid. If the oscillating liquid surface signal is detected, it indicates that the height of the oscillating liquid surface has reached a preset position threshold. Then, the speed of the motor in the motor component 131 is further reduced until it is determined that the position of the oscillating liquid surface of the cooking liquid is less than or equal to the preset position threshold.

[0093] S503, when the parameter difference in the cooking cavity is detected to meet the preset parameter difference, the control drive component 130 stops working and keeps the swing position of the disturbance structure 120 unchanged.

[0094] The parameter differences include temperature differences and / or pressure differences, and correspondingly, the preset parameter differences include preset temperature difference thresholds and / or preset pressure difference thresholds.

[0095] In some embodiments, before controlling the drive assembly 130 to stop working and maintaining the swing position of the disturbance structure 120 unchanged when the parameter difference within the cooking cavity is detected to meet a preset parameter difference, the method further includes:

[0096] Monitor the first temperature at a first position and the second temperature at a second position within the cooking cavity; the initial temperature at the first position is lower than the initial temperature at the second position.

[0097] Calculate the temperature difference between the first temperature and the second temperature;

[0098] If the temperature difference is less than or equal to a preset temperature difference threshold, the parameter difference within the cooking cavity is determined to meet the preset parameter difference.

[0099] The initial temperature refers to the temperature at which the drive component 130 is triggered to operate. The preset temperature difference threshold can be, but is not limited to, any value between 0.5℃ and 2℃, such as 0.8℃, 1℃, 1.5℃, 1.6℃, etc.

[0100] Optionally, at least two temperature sensors collect the initial temperature at various locations within the cooking cavity. The location with the lower initial temperature among the determined initial temperatures is designated as the first location, and the location with the higher initial temperature is designated as the second location. For example, temperature changes can be used to identify different parts of the food (e.g., the body and tail of a fish) and the amount of food piled up, because the amount of food at different locations and the different parts of the food absorb heat differently, resulting in different temperatures / pressures above them. Taking cooking fish as an example, regardless of how the fish is placed, the different heat absorption of the body and tail will cause different local temperatures within the pot, which will be captured by the temperature sensors on both sides. Based on these different initial temperatures, the positions of the fish body and tail are determined, i.e., the first and second locations are identified.

[0101] During the operation of the drive assembly 130, the disturbance structure 120 oscillates accordingly, thereby adjusting the temperature at various locations within the cooking cavity. Temperature sensors continuously collect the first temperature at the corresponding first location and the second temperature at the corresponding second location, transmitting the collected first and second temperatures to the controller 133. The controller calculates the temperature difference between the first and second temperatures, and if this temperature difference is less than or equal to a preset temperature difference threshold, determines that the parameter difference within the cooking cavity meets the preset parameter difference value.

[0102] In other embodiments, before controlling the drive assembly 130 to stop working and maintaining the swing position of the disturbance structure 120 unchanged after detecting that the parameter difference within the cooking cavity meets a preset parameter difference, the method further includes:

[0103] Monitor the first pressure at a first position and the second pressure at a second position within the cooking cavity; the initial pressure at the first position is less than the initial pressure at the second position.

[0104] Calculate the pressure difference between the first pressure and the second pressure;

[0105] If the pressure difference is less than or equal to the preset pressure difference threshold, the parameter difference within the cooking cavity is determined to meet the preset parameter difference.

[0106] The initial pressure refers to the pressure at which the drive component 130 is triggered to operate. The preset differential pressure threshold can be, but is not limited to, any value between 2 kPa and 9 kPa, such as 3 kPa, 7 kPa, 8.2 kPa, etc.

[0107] Optionally, at least two pressure sensors collect the initial pressure at various locations within the cooking cavity. The location with the lowest initial pressure is designated as the first location, and the location with the highest initial pressure is designated as the second location. For example, pressure changes can be used to identify different parts of the food (e.g., the body and tail of a fish) and the amount of food piled up, because the amount of food at different locations and the different parts of the food absorb heat differently, resulting in varying pressures above them. Taking cooking fish as an example, regardless of how the fish is positioned, the different heat absorption at the body and tail leads to varying local pressures within the pot, which are captured by the pressure sensors on both sides. These different initial pressures are then used to determine the positions of the fish body and tail, i.e., the first and second locations.

[0108] During the operation of the drive assembly 130, the disturbance structure 120 oscillates accordingly, thereby adjusting the pressure at various positions within the cooking cavity. Pressure sensors continuously collect the first pressure at the corresponding first position and the second pressure at the corresponding second position, transmitting the collected first and second pressures to the controller 133. The controller calculates the pressure difference between the first and second pressures, and if this pressure difference is less than or equal to a preset pressure difference threshold, it determines that the parameter difference within the cooking cavity meets the preset parameter difference value.

[0109] Further, optionally, if the temperature difference within the cooking cavity meets a preset temperature difference threshold, the controller controls the drive assembly 130 to stop working and maintains the swing position of the disturbance structure 120 unchanged. Alternatively, if the pressure difference within the cooking cavity meets a preset pressure threshold, the controller controls the drive assembly 130 to stop working and maintains the swing position of the disturbance structure 120 unchanged. Or, if both the temperature difference and pressure difference within the cooking cavity meet a preset temperature difference threshold and a preset pressure threshold, the controller controls the drive assembly 130 to stop working and maintains the swing position of the disturbance structure 120 unchanged.

[0110] This application incorporates a perturbation structure into the cooking appliance. Through the coordination of this perturbation structure with the cooking cavity and drive components, the distribution of cooking pressure within the cooking cavity is adjusted. This transforms the uniformly distributed cooking pressure into a dynamic high pressure within the pot. Consequently, when food is unevenly packed or heated in different parts of the food, the dynamic high pressure adapts to the varying heat requirements of different areas of the food, thereby improving the uniformity and quality of the cooked food, as well as enhancing its texture and flavor. Simultaneously, it also improves cooking efficiency and enhances the level of intelligent cooking.

[0111] To facilitate understanding, the following will be combined with... Figures 1 to 4 The cooking appliances and control methods of this application will be described in detail with specific embodiments:

[0112] This application provides a water-dispersing solution, specifically a water-dispersing plate installed inside the pot of a cooking appliance. The plate surface is equipped with a wireless heating wire, and one rotating end is a telescopic rod structure for easy installation inside the pot. One end of the telescopic rod is connected to a motor via a wedge-shaped fixing method, and the speed of the motor is variable.

[0113] Furthermore, during the water disturbance process, the principles governing the changes in the pressure and temperature fields within the pot of the cooking appliance are as follows: Figure 3 and Figure 4As shown, when the liquid level 310 in the pot is horizontal, the gas / pressure field above it is in a stable state. This can be understood as two gas clouds of the same size but flowing in opposite directions, with the gas pressure perpendicular to the liquid surface above 310. Utilizing the principle that the gas pressure is always perpendicular to the liquid surface 310, disturbing the water causes the liquid surface to oscillate, thus compressing the gas cloud at the rising part of the liquid surface 310. This increases the local pressure in that space, which facilitates heat penetration and thus aids cooking. The gas cloud at the lowered part of the liquid surface 310 expands, resulting in different pressure fields on both sides. This transient change in the pressure field under the continuous fluctuation of the liquid surface 310 forms dynamic high pressure. Combined with the heat absorption of the food during cooking, the phenomenon and effect of dynamic high pressure become even more pronounced.

[0114] The cooking appliance of this application includes a Bluetooth-enabled liquid level sensor, which can be fixed to both sides of the steaming rack to determine the degree of water level fluctuation. The liquid level sensor detects the water level height in real time, providing a basis for determining the motor speed. The steaming rack can be used in both steaming and stewing functions. Its use in steaming is self-evident, as it requires ventilation to hold the food. In stewing, it allows the food to be pressed down when the water level fluctuates, preventing the food from following the fluctuations and ensuring that different parts of the food are heated evenly, avoiding the aforementioned issue of the upper part of the food being steamed.

[0115] The cooking appliance of this application includes temperature / pressure sensors, which are installed on the left and right sides of the pot lid. These sensors detect the pressure field distribution inside the pot and provide signal feedback, thus providing a basis for determining the motor speed. The temperature / pressure sensor's judgment principle is based on the dynamic pressure field inside the pot and the fact that different amounts of food at different locations and different parts of the food absorb heat differently, resulting in variations in temperature / pressure above them.

[0116] In practical applications, taking steamed fish as an example, at the start of cooking, the heating wire on the water-spreading plate can be designed to be heated or not. Heating increases water evaporation efficiency but consumes more energy, while not heating reduces evaporation efficiency but saves energy. In this embodiment, it is recommended that the heating wire not work during steaming, and the heating method relies solely on the heating plate of the machine. In the early stage of cooking, when the temperature sensor detects that the temperature inside the pot reaches 100°C, or when the pressure sensor detects that the pressure inside the pot is greater than the standard atmospheric pressure, the controller controls the motor to operate, rotating in both directions for 3 seconds each, corresponding to a speed of 10 r / min to 60 r / min. When the liquid level sensor detects a liquid level signal, it indicates that the speed is too high and the water is being violently disturbed. At this time, the motor speed is reduced. This stage is a comprehensive judgment based on the motor speed and the liquid level. During the cooking process, the temperature / pressure sensor at the lid continuously monitors the pressure field distribution inside the pot. Taking the fish body and tail as an example, these sensors are located on both sides of the pot. The fish tail, with its thicker flesh, absorbs more heat, causing its temperature to drop faster. The temperature sensor signal controls the motor speed, which in turn controls the oscillation of the water-scraping plate. The control conditions can be: ensuring the temperature difference between the left and right sides is within, for example, 1.5℃ (pressure error within, for example, 7KPa), and the oscillation direction aims to increase the temperature and pressure at the fish tail. For example, the water level is higher at the fish body and lower at the tail. The principle is as follows: Figure 3 and Figure 4 At this time, the motor speed is mainly controlled by temperature / pressure signals, and is also limited by the liquid level sensor to prevent drastic fluctuations in the water level, so that the motor speed is automatically adjusted within a reasonable range.

[0117] In the stewing function, due to the larger volume of water, the heating element in the water-spreading tray can operate, which helps improve cooking efficiency. The adaptive logic of the motor speed is based on the principle described above. Taking meat chunks as an example, the degree of heat absorption varies depending on the amount of food piled up in the pot and the size of the food itself. A larger pile and larger meat chunks absorb more heat. The control principles and logic for other processes are as described above.
