Description

Technical Field

[0002] In the kitchen appliance industry, anti-overflow control has always been a core technology for improving user experience and safety. Traditional anti-overflow methods mainly include: passive physical design and trigger control. Passive physical design uses a high-arched lid to expand the steam buffer space or adds an anti-overflow baffle to block the rise of foam. However, this method can only delay the overflow time and cannot cope with violent boiling scenarios. Trigger control can cut off heating when the liquid touches the electrode or reduce the heating power when a sudden change in the rate of temperature rise is detected. This type of method has obvious response lag and over-response, and is prone to accidental stopping of heating due to accidental touch, thus prolonging cooking time.

This specification provides the method operation steps as shown in the embodiment, but based on conventional or non-creative labor, more or fewer operation steps may be included. The order of steps listed in the embodiment is merely one possible execution order among many steps and does not represent the only execution order. In actual control method execution, the method can be executed in the order shown in the embodiment or the accompanying drawings, or in parallel. The following, in conjunction with... Figure 1 This application introduces a control method for a smart kitchen appliance, which includes a cooking appliance and a heating device. The cooking appliance is equipped with a liquid level sensor, and the control method includes steps S100-S300.

[0022] S100: During the heating process of the heating device, acquire liquid level information inside the cooking appliance.

[0023] In some embodiments, the liquid level information is acquired by a liquid level sensor, and the liquid level information represents the liquid level height inside the cooking appliance. In other embodiments, the liquid level information can represent the rate of change of the liquid level height inside the cooking appliance. The rate of change of the liquid level height indicates the rate of change of the liquid level height within a first preset time period. The rate of change of the liquid level height can quantitatively describe the trend of liquid level height change and can be used to predict changes in the liquid level height.

[0024] In a possible implementation, the cooking appliance may include a top cover and a body, with the top cover covering the opening of the body and the body used to hold the food and liquid to be cooked; specifically, a liquid level sensor is used to collect the height of the liquid in the body, or the distance between the liquid level and the top cover.

[0025] In a possible implementation, the liquid level information is used to characterize the real-time liquid level height inside the cooking appliance, providing real-time feedback on changes in the liquid level within the appliance. Specifically, steam foam is generated during the boiling process of the liquid; in this case, the liquid level information is used to characterize the height of both the liquid and the steam foam within the cooking appliance.

[0026] In a possible implementation, the smart kitchen appliance is equipped with a temperature sensor for collecting temperature information within the cooking appliance. The method of acquiring liquid level information inside the cooking appliance during the heating process further includes: S110: During the heating process of the heating device, temperature information collected by the temperature sensor is obtained. The temperature information represents the temperature value of the liquid inside the cooking appliance. S120: When the temperature information is greater than or equal to the preset temperature, obtain the liquid level information inside the cooking appliance.

[0027] In this embodiment, the preset temperature is used to characterize the boiling threshold of the liquid in the cooking appliance. When the temperature information is lower than the preset temperature, it indicates that the liquid in the cooking appliance is in a safe heating state. When the temperature information reaches the preset temperature, it indicates that the liquid has reached the boiling state. The liquid level information is obtained when the liquid reaches the boiling state, which helps to simplify the operation steps.

[0028] S200: Based on the first preset correspondence, select the target control strategy that matches the liquid level information from multiple preset control strategies. The first preset correspondence represents the mapping relationship between multiple liquid level information and multiple preset control strategies.

[0029] In one specific embodiment, the first preset correspondence can be a mapping relationship between multiple liquid level heights and multiple preset control strategies. Specifically, in the first preset correspondence, different liquid level height values ​​correspond to different preset control strategies.

[0030] In another specific embodiment, the first preset correspondence can be a mapping relationship between multiple liquid level height ranges and multiple preset control strategies. Specifically, in the first preset correspondence, different liquid level height ranges correspond to different preset control strategies, and the liquid level height value corresponding to the liquid level information corresponds to the same preset control strategy within the same liquid level height range.

[0031] In a possible implementation, the preset control strategy can be a method of controlling at least one of the cooking appliance and the heating device after the liquid level information reaches the target liquid level. The preset control strategy is used to control the operation mode of the smart kitchen appliance. Specifically, the preset control strategy is used to control at least one of the opening and closing angle of the cooking appliance lid and the heating power of the heating device.

[0032] Specifically, the above-mentioned selection of a target control strategy matching the liquid level information from multiple preset control strategies based on a first preset correspondence includes: selecting a target control strategy matching the liquid level information from multiple control strategies based on the numerical relationship between the liquid level information and preset liquid level information, and the first preset correspondence between the preset liquid level information and the control strategy. Specifically, the target control strategy represents a control method that can effectively prevent liquid overflow from inside the cooking appliance at the current liquid level height, and the target control strategy is used to adjust the working state of the smart kitchen appliance; specifically, the target control strategy is used to adjust at least one of the opening angle of the cooking appliance's lid and the heating power of the heating device, thereby preventing liquid overflow from inside the cooking appliance while ensuring cooking efficiency.

[0033] In a possible implementation, the liquid level information is used to indicate the liquid level height. The above-mentioned selection of a target control strategy that matches the liquid level information from multiple control strategies based on the numerical relationship between the liquid level information and preset liquid level information, and the first preset correspondence between the preset liquid level information and the control strategy, includes: selecting a target control strategy that matches the numerical relationship between the current liquid level height and preset liquid level height, and the first preset correspondence between the preset liquid level height and the control strategy.

[0034] In a possible implementation, the liquid level information is used to indicate the rate of change of liquid level height. The aforementioned method of selecting a target control strategy matching the liquid level information from multiple control strategies based on the numerical relationship between the current liquid level information and preset liquid level information, as well as the first preset correspondence between the preset liquid level information and the control strategy, includes: selecting a target control strategy matching the numerical relationship between the current rate of change of liquid level height and a preset rate of change, as well as the first preset correspondence between the preset rate of change and the control strategy. In this way, the trend of liquid level change can be predicted based on the rate of change of liquid level height, and the control strategy can be configured in a timely manner to prevent a rapid rise in liquid level height leading to liquid overflow and avoid response delays in the control method.

[0035] S300: Adjusts at least one of the opening angle of the lid of the cooking appliance and the heating power of the heating device according to the target control strategy, so that the smart kitchen appliance meets the safety status of preventing overflow.

[0036] Specifically, when the lid of the cooking appliance is connected to the main body, steam continuously accumulates within the appliance's sealed cavity, causing an increase in internal pressure. This leads to violent vaporization of the liquid, resulting in expanding bubbles. If the bubble volume exceeds the appliance's capacity, the liquid will overflow. Adjusting the opening angle of the cooking appliance releases steam, allowing the internal pressure to return to normal, slowing down bubble formation, and thus preventing liquid overflow.

[0037] In a possible implementation, the opening angle of the lid is adjusted to a preset angle according to the target control strategy. Understandably, when the lid is open, a large amount of heat inside the cooking appliance is lost to the air through steam, causing the temperature inside the appliance to drop rapidly. Controlling the opening angle of the lid to a preset angle can prevent liquid spillage while avoiding a significant loss of heat from the cooking appliance, thus preventing a decrease in cooking efficiency.

[0038] The heating efficiency of a heating device directly affects the amount of heat transferred to the cooking appliance per unit time. The liquid inside the cooking appliance absorbs heat and is converted into steam. The rate of steam generation depends on the heating power. Adjusting the heating power of the heating device can reduce the rate of steam and bubble generation, thereby preventing liquid from overflowing.

[0039] In a possible implementation, the heating power of the heating device is adjusted to a preset power according to the target strategy. It is understood that reducing the heating power of the heating device reduces the heat transferred to the cooking appliance, thereby decreasing the rate of steam generation inside the appliance. Controlling the heating power to the preset power can reduce the heating power to prevent liquid overflow while maintaining cooking efficiency.

[0040] In this way, by obtaining the liquid level in the cooking appliance, changes in the liquid level can be monitored in real time, and an appropriate target control strategy can be configured based on the liquid level. Then, based on the target control strategy, at least one of the opening and closing angle of the cooking appliance lid and the heating power of the heating device can be controlled to avoid liquid overflow or dry burning in the cooking appliance. It can adapt to various ingredients and heating scenarios, which helps to improve cooking safety and user operation convenience. Precise control can avoid energy waste, which helps to reduce the energy consumption of smart kitchen appliances and thus extend the service life of the equipment.

[0041] In a possible implementation, the liquid level information is used to indicate the liquid level height. The above-mentioned selection of a target control strategy matching the liquid level information from multiple preset control strategies based on a first preset correspondence includes: S211: When the liquid level is greater than or equal to the first preset height and less than the second preset height, the first control strategy is configured as the target control strategy.

[0042] Specifically, the first preset height is used to indicate the liquid level when there is a first risk of spillage inside the cooking appliance. When the liquid level is lower than the first preset height, it indicates that the liquid level inside the cooking appliance is in a safe state. When the liquid level is within this range, the smart cookware is in normal cooking mode, the top cover of the cooking appliance is closed to the body of the cooking appliance, and the heating power of the heating device is the initial heating power set by the user.

[0043] Specifically, the second preset height is used to indicate the liquid level when there is a second risk of spillage inside the cooking appliance. When the liquid level is greater than or equal to the first preset height but less than the second preset height, it indicates that the liquid level inside the cooking appliance has risen compared to the initial liquid level, and there is a first risk of spillage. At this time, the first control strategy is configured as a target control strategy to control the cooking state of the smart cookware and prevent the liquid level inside the cooking appliance from continuing to rise and causing spillage. Understandably, the first preset height is less than the second preset height, and both the first and second preset heights can be adjusted according to the actual cooking situation.

[0044] In a possible implementation, the liquid level information is used to indicate the rate of change of liquid level height. The above-mentioned selection of a target control strategy matching the liquid level information from multiple preset control strategies based on a first preset correspondence includes: S221: When the rate of change of liquid level height is greater than or equal to the first preset rate of change and less than the second preset rate of change, the first control strategy is configured as the target control strategy.

[0045] In some embodiments, the first preset rate of change can be 0, indicating that the liquid level no longer rises; in other embodiments, the first preset rate of change can be negative, indicating that the liquid level falls. When the liquid level change rate is the first rate of change, the liquid inside the cooking appliance is in a stable state. The second preset rate of change is used to indicate the rate of change of the liquid level when it slowly increases. When the rate of change of the liquid level is greater than or equal to the first preset rate of change and less than the second preset rate of change, it indicates that the liquid level inside the cooking appliance is gradually rising, and there is a risk of spillage. It is understood that the first preset rate of change is less than the second preset rate of change, and the first preset rate of change and the second preset rate of change can be adjusted according to the actual cooking situation.

[0046] In a possible implementation, when the rate of change of liquid level height is continuously less than the first preset rate of change within a second preset time period, a third warning message is generated; the third warning message is used to indicate that the liquid level in the cooking appliance continues to drop within the second preset time period, and the cooking appliance is at risk of dry burning.

[0047] In some embodiments, after configuring the first control strategy as a target control strategy, adjusting at least one of the opening angle of the cooking appliance's lid and the heating power of the heating device according to the target control strategy until the smart kitchen appliance meets the anti-overflow safety condition includes: S310: According to the first control strategy, control the opening and closing angle to a preset angle so that the smart kitchen appliance meets the safety requirements for preventing overflow.

[0048] In this embodiment, the first control strategy is used to control the opening and closing angle of the lid of the cooking appliance. In a possible implementation, the cooking appliance is equipped with a transmission device, and the lid and the main body of the cooking appliance are connected through the transmission device. The transmission device can drive the lid to rotate relative to the opening of the main body. Specifically, the transmission device is electrically connected to the control device of the smart kitchen appliance. The control device is configured to control the transmission device according to the target control strategy, thereby controlling the opening and closing angle between the lid and the main body.

[0049] Specifically, the preset angle can represent the opening and closing angle corresponding to the current liquid level. The preset angle can be a fixed value set by the user. When the opening and closing angle is controlled to the preset angle, the hot steam in the cooking appliance can overflow, thereby causing the liquid level in the cooking appliance to drop and preventing the liquid level from rising continuously and causing the liquid to overflow.

[0050] Specifically, when the real-time liquid level inside the cooking appliance is less than or equal to the liquid level at the previous moment, and the liquid level inside the cooking appliance no longer continues to rise, it proves that the smart kitchen appliance meets the safety requirements for preventing overflow.

[0051] In a possible implementation, different liquid levels correspond to different preset angles; specifically, controlling the opening / closing angle to a preset angle according to the first control strategy includes: S3101: Based on the second preset correspondence, a preset angle matching the liquid level is selected from multiple opening and closing angle data, and the opening and closing angle is controlled to be the preset angle; the second preset correspondence represents the mapping relationship between the liquid level height and the opening and closing angle data.

[0052] In a possible implementation, the second preset correspondence can be a mapping relationship between multiple liquid level heights and multiple opening / closing angle data. Specifically, in the second preset correspondence, different liquid level heights correspond to different opening / closing angle data. In this way, the opening / closing angle of the lid can be adjusted in real time according to changes in liquid level height, ensuring that the opening / closing angle meets the spill prevention requirements, achieving pressure and thermal balance inside the cooking appliance, and preventing excessive heat loss that would reduce cooking efficiency.

[0053] Specifically, the preset angle is positively correlated with the liquid level. Within the range of the first preset height to the second preset height, as the liquid level rises, the opening and closing angle data corresponding to the liquid level increases, and the preset angle obtained by filtering increases.

[0054] In one example, the relationship between the liquid level height and the opening / closing angle is Y / Y. max =(h-h1) / (h2-h1), where Y is the opening angle, Y max The maximum opening angle is given by h, the real-time liquid level height is given by h1, the first preset height is given by h2, and the second preset height is given by h2. Thus, when the real-time liquid level height increases, the opening angle of the top cover increases, and the degree of opening of the top cover relative to the main body is positively correlated with the liquid level height.

[0055] In a possible implementation, based on a first preset correspondence, a target control strategy matching the liquid level information is selected from multiple preset control strategies, and the method further includes: S212: When the liquid level is greater than or equal to the second preset height and less than the third preset height, the second control strategy is configured as the target control strategy.

[0056] Specifically, the third preset height indicates the liquid level inside the cooking appliance when it is about to overflow. When the liquid level is greater than or equal to the second preset height but less than the third preset height, it indicates that the liquid level inside the cooking appliance has risen significantly compared to the initial liquid level, and the liquid is about to overflow. At this time, the second control strategy is configured as the target control strategy to control the cooking state of the smart cookware and prevent the liquid level inside the cooking appliance from continuing to rise and causing overflow. Understandably, the third preset height is greater than the second preset height, and both the third and second preset heights can be adjusted according to the actual cooking situation.

[0057] In a possible implementation, the liquid level information indicates the rate of change of liquid level height. The above-mentioned selection of a target control strategy matching the liquid level information from multiple preset control strategies based on a first preset correspondence includes: S222: When the rate of change of liquid level height is greater than or equal to the second preset rate of change and less than the third preset rate of change, the second control strategy is configured as the target control strategy.

[0058] Specifically, the third preset rate of change is used to indicate the rate of change of the liquid level when it rises rapidly within the cooking appliance. When the rate of change of the liquid level is greater than or equal to the second preset rate of change and less than the third preset rate of change, it indicates that the liquid level inside the cooking appliance is rising rapidly. At this time, the second control strategy is configured as the target control strategy to promptly control the cooking state of the smart cookware, curb the continuous rise in liquid level, and prevent liquid overflow. Understandably, the third preset rate of change is greater than the second preset rate of change, and it can be adjusted according to the actual cooking situation.

[0059] In some embodiments, after configuring the second control strategy as a target control strategy, adjusting at least one of the opening angle of the cooking appliance's lid and the heating power of the heating device according to the target control strategy until the smart kitchen appliance meets the anti-overflow safety condition includes: S320: According to the second control strategy, the opening and closing angle is controlled to reach the opening and closing angle threshold, and the heating power of the heating device is the preset power, so that the smart kitchen appliance meets the safety status of preventing overflow.

[0060] In this embodiment, the liquid level is greater than the second preset height, and the opening angle of the top cover has reached the opening angle threshold. The second control strategy is used to control the heating power of the heating device. In a possible implementation, the heating device includes a manual valve and an electric valve. The user sets the initial heating power of the heating device by opening the manual valve and adjusting its rotation angle. The electric valve is electrically connected to the control device, which is configured to control the opening degree of the electric valve according to the second control strategy until the heating power of the heating device is the preset power.

[0061] Specifically, the preset power can represent the heating power corresponding to the current liquid level. The preset power can be a set value set by the user. When the heating power is controlled to the preset power, the heat transferred from the heating device to the cooking appliance can be reduced, the heating rate of the liquid inside the cooking appliance can be slowed down, thereby reducing the steam generation rate, reducing the amount of bubbles generated, and preventing the liquid level from rising continuously and causing the liquid to overflow.

[0062] In a possible implementation, according to the second control strategy, the opening and closing angle is controlled to reach an opening and closing angle threshold, and the heating power of the heating device is a preset power, including: S3201: Based on the third preset correspondence, a preset power that matches the liquid level height is selected from multiple heating power data, and the heating power is controlled to a preset angle; the third preset correspondence represents the mapping relationship between the liquid level height and the heating power data.

[0063] In a possible implementation, the third preset correspondence can be a mapping relationship between multiple liquid level heights and multiple heating power data. Specifically, in the second preset correspondence, different liquid level heights correspond to different heating power data. In this way, the heating power of the heating device can be adjusted in real time according to changes in liquid level height, ensuring that the heating power meets the anti-overflow requirements, achieving pressure and thermal balance inside the cooking appliance, while avoiding reduced cooking efficiency due to insufficient heating power.

[0064] Specifically, the heating power is negatively correlated with the liquid level. Within the range of the second preset height to the third preset height, as the liquid level rises, the heating power data corresponding to the liquid level decreases, and the preset angle obtained by screening decreases.

[0065] In one example, the relationship between the liquid level and the heating power is X / X0=1-(h-h2) / (h3-h2), where X is the heating power, X0 is the initial heating power, h is the real-time liquid level, h2 is the second preset height, and h3 is the third preset height. Thus, when the real-time liquid level increases, the heating power decreases from the value of the initial heating power.

[0066] In a possible implementation, based on a first preset correspondence, a target control strategy matching the liquid level information is selected from multiple preset control strategies, and the method further includes: S213: When the liquid level is greater than or equal to the third preset height, the third control strategy will be configured as the target control strategy; When the liquid level is greater than or equal to the third preset height, it indicates that the liquid level in the cooking appliance has reached the point of overflow. The third control strategy is used to simultaneously control the opening and closing angle of the top cover and the heating power of the heating device to prevent the liquid level in the cooking appliance from continuing to rise.

[0067] In a possible implementation, the liquid level information is used to indicate the rate of change of liquid level height. The above-mentioned selection of a target control strategy matching the liquid level information from multiple preset control strategies based on a first preset correspondence includes: S223: When the rate of change of liquid level height is greater than or equal to the third preset rate of change, the third control strategy will be configured as the target control strategy.

[0068] Specifically, when the rate of change of liquid level is greater than or equal to the third preset rate of change, it indicates that the liquid level in the cooking appliance is abnormally high and there is a high risk of overflow. At this time, configuring the third control strategy as the target control strategy can effectively prevent the liquid level from continuing to rise.

[0069] In some embodiments, after configuring the third control strategy as the target control strategy, adjusting at least one of the opening angle of the cooking appliance's lid and the heating power of the heating device according to the target control strategy until the smart kitchen appliance meets the anti-overflow safety condition includes: S330: According to the third control strategy, the opening and closing angle is controlled to the opening and closing angle threshold, the heating device stops heating, and the first warning message is generated.

[0070] In this embodiment, when the liquid level is greater than the third preset height, the liquid inside the cooking appliance is about to overflow. The third control strategy is used to control the opening and closing angle of the top cover to the opening and closing angle threshold and to control the heating device to stop heating to prevent the liquid level from continuing to rise. The first warning information is used to remind the user that there is a risk of the cooking appliance overflowing and to indicate the current working status of the smart kitchen appliance.

[0071] In a possible implementation, the smart kitchen appliance is equipped with an alarm that is electrically connected to the control device. After generating the first warning message, the alarm is activated to remind the user that there is a risk of the pot overflowing during the cooking process, and cooking is stopped.

[0072] In a possible implementation, the above-mentioned selection of a target control strategy that matches the liquid level information from multiple preset control strategies based on a first preset correspondence further includes: S240: When the liquid level is less than the fourth preset height, the fourth control strategy will be configured as the target control strategy. After configuring the fourth control strategy as the target control strategy, the control method also includes: S340: According to the fourth control strategy, control the heating device to stop heating and generate a second warning message.

[0073] In this embodiment, the fourth preset height represents the minimum liquid level at which the cooking appliance can perform cooking. When the liquid level is lower than the fourth preset height, it indicates that the liquid level inside the cooking appliance has dropped significantly compared to the initial liquid level. At this time, the fourth control strategy is configured as the target control strategy, stopping further heating of the cooking appliance. This avoids the cooking appliance from drying out due to the continuous drop in the liquid level inside, and a second warning message is generated to remind the user of the risk of dry burning during cooking, thus stopping the cooking process. It is understood that the fourth preset height is lower than the first preset height, and the fourth preset height can be adjusted according to the actual cooking situation.

[0074] In a possible implementation, the cooking appliance is equipped with a position sensor, and the control method includes: S400: Acquires position information collected by the position sensor, which represents the relative position between the main body and the top cover of the cooking appliance; S500: Generates reminder information based on the relationship between preset start conditions and location and liquid level information; preset start conditions represent preset location and liquid level information that meet cooking conditions.

[0075] Specifically, the position information can be used to determine whether the top cover of the cooking appliance is closed to the main body; the preset position information indicates that the top cover is closed to the main body. When the position information meets the preset position information, it proves that the top cover of the cooking appliance is connected to the main body, the top cover is closed to the main body, and can open at a preset angle relative to the main body.

[0076] Specifically, the preset liquid level information indicates that the liquid level in the cooking appliance is less than the first preset height. When the liquid level information meets the preset liquid level information, it proves that the liquid level in the main body is lower than the first preset height and the liquid level is in a safe liquid level state.

[0077] In a possible implementation, when both the location information and liquid level information meet the preset start-up conditions, a first prompt message is generated to remind the user that cooking can begin in this state. If at least one of the location information or liquid level information does not meet the preset start-up conditions, a second prompt message is generated to remind the user that the smart kitchen appliance does not meet the conditions for starting cooking in this state. Specifically, the second prompt message can prompt the user to adjust the position of the top cover and the liquid level inside the main body. Thus, detecting the status of the smart kitchen appliance before starting cooking and providing prompts to the user helps improve cooking safety.

[0078] In a possible implementation, the heating device is activated when the liquid level information does not meet the preset start-up conditions, and a second prompt message is generated; when the position information does not meet the preset start-up conditions, a second prompt message is generated, and the second control strategy is configured as the target control strategy.
