[0036] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] The control method of the anti-overflow cooker provided in the embodiment of the present application can be applied to the cooker. Figure 1 As shown, the cooker includes a controller 101, an oxygen sensor 102 and an anti-overflow cooker 103. The oxygen sensor 102 is arranged on the top of the pot cover of the anti-overflow cooker 103. The oxygen sensor 102 is connected to the controller 101 and can be connected via Bluetooth, 5G or WiFi.

[0046] The controller 101 is configured to obtain multiple oxygen levels within the anti-overflow cooker 103, as collected by the oxygen sensor 102, during the cooking process of the anti-overflow cooker 103. Based on the multiple oxygen levels, the controller 101 determines a rate of change of the oxygen content within the anti-overflow cooker 103. If the rate of change of the oxygen content exceeds a threshold oxygen content change rate, the controller 101 reduces the first power value of the anti-overflow cooker 103 according to a preset power adjustment rule. The threshold oxygen content change rate is the oxygen content at which the anti-overflow cooker 103 overflows after cooking at the oxygen content change rate threshold for a preset duration.

[0047] The oxygen sensor 102 is used to collect the oxygen content inside the anti-overflow cooker 103 and send the oxygen content to the controller 101.

[0048] The following will describe in detail a method for controlling an overflow prevention pot provided by an embodiment of the present application in conjunction with specific implementation methods. Figure 2 This is a flow chart of a method for controlling an overflow prevention pot provided in an embodiment of the present application, such as Figure 2 The specific steps are as follows:

[0049] Step 201 : During a cooking process of the anti-overflow cooker, a plurality of oxygen contents in the anti-overflow cooker collected by an oxygen sensor are obtained.

[0050] As the saying goes, "a kitchen is incomplete without a stove." As the core of Chinese cooking, stoves provide the most basic and most practical cooking equipment for countless Chinese families. As people's living standards continue to improve, the demand for stoves is also increasing, and the need for spill-resistant stoves is growing stronger. Overflowing a pot involves bubble dynamics. Bubbles in boiling water have low tension, so they easily burst upon leaving the water surface and rarely overflow. However, when cooking porridge or noodles, food contains macromolecules such as proteins. Due to the repulsive properties of the hydrophilic and lipophilic groups of these macromolecules, surface tension forms bubbles when the water boils. After a period of accumulation, these bubbles rapidly increase, causing overflow. During the cooking process, the increased surface tension leads to a large number of bubbles. Simultaneously, these bubbles contain steam. Therefore, as these bubbles accumulate, the steam above the pot decreases. Since air contains more steam and less oxygen, it contains less steam. Therefore, as the steam above the pot decreases, the oxygen content increases. Therefore, by detecting the rate of change in the oxygen content, we can determine the increase or decrease in steam, and then predict the overflow of the pot and avoid it. Therefore, an oxygen content sensor can be installed inside the pot lid of the anti-overflow pot stove. During the cooking process of the anti-overflow pot stove, the oxygen content inside the anti-overflow pot stove collected by the oxygen sensor is obtained.

[0051] Step 202: Determine the rate of change of the oxygen content in the anti-overflow cooker based on the multiple oxygen contents.

[0052] In practice, if this application wants to judge overflow in advance and avoid the possibility of overflow in advance, it is necessary to know the characteristics of overflow in advance. Because when there is more steam in the air, there is less oxygen, and when there is less steam, there is more oxygen. When there are more bubbles in the pot, the steam above the pot will decrease. When the steam above the pot decreases, the oxygen content above the pot increases. Therefore, by detecting its oxygen content, the increase or decrease of steam can be judged, and then the overflow of the pot can be predicted to avoid overflow. Therefore, after obtaining multiple oxygen contents in the anti-overflow stove collected by the oxygen content sensor, the rate of change of the oxygen content in the anti-overflow stove can be determined through the multiple oxygen contents. Subsequently, the possibility of overflow can be judged in advance based on the rate of change of the oxygen content.

[0053] Specifically, the plurality of oxygen contents include a first oxygen content and a second oxygen content. The difference between the first oxygen content and the second oxygen content is determined as the oxygen content change rate in the anti-overflow cooker, where the first oxygen content is the oxygen content at the time corresponding to the second oxygen content after a preset time period.

[0054] In practice, when the pot is about to overflow, the oxygen content at the top of the anti-overflow cooker increases. Therefore, whether the anti-overflow cooker is about to overflow can be determined based on the rate of increase in the oxygen content. Therefore, the difference between the first oxygen content and the second oxygen content can be determined as the rate of change of the oxygen content in the anti-overflow cooker. The first oxygen content is the oxygen content at the time corresponding to the second oxygen content after a preset period of time.

[0055] As an optional implementation, the difference between the first oxygen content and the second oxygen content is determined as the formula for the oxygen content change rate in the anti-overflow cooker:

[0056] v=S t -S t-△t

[0057] Where v represents the rate of change of oxygen content, S t Indicates the first oxygen content, S t-△t represents the second oxygen content, t represents the time corresponding to the second oxygen content, and Δt represents the preset time duration.

[0058] In step 203, if the oxygen content change rate is greater than the oxygen content change rate threshold, the first firepower value of the anti-overflow stove is reduced according to a preset firepower adjustment rule. The oxygen content change rate threshold is the oxygen content at which the anti-overflow stove overflows after the anti-overflow stove continues cooking for a preset time threshold according to the oxygen content change rate threshold.

[0059] In implementation, the oxygen content change rate is compared with an oxygen content change rate threshold. If the oxygen content change rate exceeds the oxygen content change rate threshold, it indicates that the oxygen content within the anti-overflow cooker has increased and exceeded the threshold, indicating that the amount of steam above the anti-overflow cooker has decreased. Simultaneously, there is more steam on the surface and inside the cooker, representing more bubbles. A high number of bubbles indicates that overflow is accumulating and there is a risk of imminent overflow. In this case, the heat of the anti-overflow cooker should be lowered to prevent the risk of overflow. The oxygen content change rate threshold is the oxygen content at which the anti-overflow cooker overflows after cooking for a preset time period, as measured by the oxygen content change rate threshold. In other words, if the oxygen content change rate within the anti-overflow cooker exceeds the oxygen content change rate threshold, the cooker will overflow after cooking for another preset time period. Therefore, to allow sufficient time for the anti-overflow cooker to process, the first heat value of the anti-overflow cooker should be lowered when the oxygen content change rate exceeds the oxygen content change rate threshold. In this way, by capturing the characteristics of the oxygen content change rate of the anti-overflow stove before overflow, anti-overflow processing operations can be performed according to the characteristics of the oxygen content change rate before overflow, the firepower value can be reduced, and the possibility of anti-overflow can be fundamentally eliminated, thereby achieving zero overflow.

[0060] Furthermore, the specific steps of executing the preset firepower adjustment rule to reduce the first firepower value of the anti-overflow cooker are as follows:

[0061] Step 1: reduce the first firepower value of the anti-overflow cooker to a second firepower value obtained by multiplying a preset proportional coefficient by the first firepower value.

[0062] In practice, if the rate of change of the oxygen content within the anti-overflow cooker exceeds a threshold oxygen content change rate, the cooker will overflow after cooking continues for a preset threshold time. Therefore, the anti-overflow cooker's heat level needs to be promptly reduced to prevent the possibility of overflow. The anti-overflow cooker's first heat level is reduced to a second heat level that is the product of a preset proportional coefficient and the first heat level. The preset proportional coefficient can be 50%, so that the reduction in heat level is neither too large, resulting in an excessively long cooking time, nor too small, resulting in the possibility of overflow on the anti-overflow cooker. In practical applications, the preset proportional coefficient can also be other values, which are not limited here.

[0063] Step 2: After cooking for a preset time at the second firepower value, determine the updated oxygen content change rate of the anti-overflow cooker.

[0064] In practice, after cooking for a preset period at the second firepower value, it is necessary to re-evaluate whether the current anti-overflow stove is still at risk of overflow. If so, anti-overflow control must continue. If not, cooking continues at the current second firepower value. Therefore, to determine whether the current anti-overflow stove is at risk of overflow, it is necessary to obtain multiple oxygen levels of the current anti-overflow stove and determine the updated rate of change of the oxygen content of the anti-overflow stove based on the multiple oxygen levels. Subsequently, the rate of change of the oxygen content is used to determine whether the risk of overflow still exists.

[0065] Step three: If the updated oxygen content change rate is greater than the oxygen content change rate threshold, the second firepower value is reduced to a third firepower value that is the product of the preset proportional coefficient and the second firepower value, and the updated oxygen content change rate in the anti-overflow pot stove is determined until the determined oxygen content change rate of the anti-overflow pot stove is less than or equal to the oxygen content change rate threshold.

[0066] In implementation, after determining the updated oxygen content rate of change, it is necessary to determine whether overflow is still a possibility based on the updated oxygen content rate of change. Therefore, the updated oxygen content rate of change is compared with a threshold oxygen content rate of change. If the updated oxygen content rate of change is still greater than the threshold oxygen content rate of change, it indicates that the oxygen content within the anti-overflow cooker is still high, and the amount of steam above the anti-overflow cooker is reduced. In other words, there is more steam on the surface and inside the anti-overflow cooker, resulting in more bubbles. A high number of bubbles indicates that overflow is accumulating and there is a risk of imminent overflow. In this case, the heat of the anti-overflow cooker needs to be lowered to avoid the risk of overflow. Therefore, if the updated oxygen content rate of change is greater than the threshold oxygen content rate of change, the second heat value is reduced to a third heat value that is the product of a preset proportional coefficient and the second heat value. Then, it is necessary to continue obtaining updated oxygen content and determining the updated oxygen content rate of change within the anti-overflow cooker until the oxygen content rate of change within the anti-overflow cooker is less than or equal to the threshold oxygen content rate of change. In other words, the system needs to constantly check whether the anti-overflow stove has the potential to overflow until it is confirmed by the rate of change in oxygen content that there is no risk of overflow. The system then maintains the current firepower value. Otherwise, the system continues to reduce the firepower value. This ensures that there is no risk of overflow, thus achieving zero overflow.

[0067] Furthermore, the oxygen content change rate threshold is the oxygen content at which the anti-overflow stove overflows after the anti-overflow stove continues cooking for a preset time threshold according to the oxygen content change rate threshold. Therefore, the process of determining the oxygen content change rate threshold is:

[0068] For example, cooking porridge: use an aluminum pot with a height of 19 cm to cook porridge, with a rice-to-water ratio of 1:8, 500g rice, 4000g water, and cook over high heat after soaking for 2 hours. After boiling, turn to low heat, open the lid after the pot overflows, stir it thoroughly, and then cover and cook. Among them, the change in pot height will cause fluctuations in oxygen content, which will have a certain impact on the time from the bottom to the sensor. That is to say, the prediction time of overflow of the anti-overflow stove after cooking for a preset time threshold according to the oxygen content change rate threshold may change. Then, during the low heat process, start monitoring the changes in oxygen content and the rate of change of oxygen content. In this way, during the low heat cooking process, the rate of change of oxygen content will not be too fast, and the time from prediction to overflow will be longer, leaving the user with a longer anti-overflow processing time. And when cooking over low heat, the water will not be boiled dry, and the rice will absorb water and become plump and softened. For example Figure 3 As shown in the figure, during the low fire process, the oxygen content curve shows a trend of first decreasing and then increasing, and then overflowing occurs. During the process of cooking porridge with the lid on, the oxygen content curve shows a trend of first decreasing and then decreasing to equilibrium. Figure 3As can be seen from the figure, at 219 seconds, the oxygen content change rate V value reached 0.21, which is greater than 0.2, and overflow occurred at 304 seconds. In other words, there are 85 seconds between the judgment of overflow possibility and the actual overflow, which is enough time to take anti-overflow measures. Therefore, the oxygen content change rate of 0.2 is determined as the oxygen content change rate threshold. Figure 3 The figure shows an oxygen content change threshold curve of 0.2. This allows the user or controller to perform an overflow prevention operation for 85 seconds after the oxygen content change rate in the oxygen content change rate curve reaches the oxygen content change rate threshold. This simulates the user actually cooking porridge, where thorough stirring diffuses the heat hidden within the porridge, achieving consistent temperature and characteristics (consistent energy per unit volume) throughout the pot. This results in a longer preset time for overflow prevention after the oxygen content change rate reaches the threshold.

[0069] For example, cooking porridge 2: use an aluminum pot with a height of 19 cm to cook porridge, with a rice-water ratio of 1:8, 500g rice, 4000g water, and cook over high heat after soaking for 2 hours. Turn to low heat after boiling, open the lid after the pot overflows, stir lightly, and then cover and cook. Lightly stir to remove the bubbles on the surface, but there may still be a lot of bubbles inside. The temperature at different positions in the pot may be different, and the characteristics are different. In comparison, light stirring will cause the porridge to overflow faster and the prediction time is shorter because bubbles have accumulated inside the porridge. Then, during the low heat process, start monitoring the changes in oxygen content and the rate of change of oxygen content. For example Figure 4 As shown in the figure, during the cooking process with low heat, the oxygen content curve shows a trend of first decreasing, then increasing, and then overflowing occurs. During the cooking process with the lid on, the oxygen content curve shows a trend of first decreasing, then decreasing to equilibrium. Figure 4 It can be seen that at 280 seconds, the oxygen content change rate V value in the oxygen content change rate curve reached 0.23, which is greater than 0.2, and overflow occurred at 312 seconds. In other words, there are 32 seconds between the judgment of overflow possibility and the actual overflow, which is enough time to take anti-overflow measures. Therefore, the oxygen content change rate of 0.2 is determined as the oxygen content change rate threshold. Figure 4 The oxygen content change threshold curve of 0.2 in the figure gives the user or controller 32 seconds to take anti-overflow action after the oxygen content change rate reaches the threshold. Therefore, by monitoring oxygen content changes, if the oxygen content change rate V>0.2 (every 10 seconds), it can be determined that overflow is accumulating, and the heat can be reduced or other defoaming measures can be taken.

[0070] To summarize, when an oxygen sensor is used to control overflow, under low heat, based on the different amounts of bubbles in the pot of the anti-overflow stove (opening the lid after overflow, stirring slightly, then covering the pot and cooking, and opening the lid after overflow, stirring fully, then covering the pot and cooking), after the oxygen content change rate reaches the oxygen content change rate threshold, there is at least 32s-85s to control overflow. Specifically, overflow control can be carried out by reminding the user to stir, reducing the firepower of the controller, or releasing the pressure.

[0071] Furthermore, if the oxygen content change rate is greater than the oxygen content change rate threshold, a voice prompt is issued, and the voice prompt is used to prompt the user to stir or release the pressure.

[0072] During implementation, when the rate of change of the oxygen content at the top of the anti-overflow stove is greater than the oxygen content change rate threshold, in addition to controlling the reduction of the firepower value of the anti-overflow stove, a voice prompt can also be issued. The voice prompt is used to prompt the user to stir, release pressure or manually reduce the firepower value to perform anti-overflow processing.

[0073] Furthermore, if the oxygen content change rate is less than or equal to the oxygen content change rate threshold, the first firepower value is maintained unchanged.

[0074] In practice, when the rate of change of the oxygen content at the top of the anti-overflow cooker is less than or equal to the oxygen content change rate threshold, it indicates that the oxygen content within the anti-overflow cooker is currently low. Since the air has more steam, it has less oxygen, and less steam, it has more oxygen. Therefore, when the oxygen content at the top of the cooker is low, there is more steam. Consequently, there is less steam on the surface and inside the porridge or noodles cooked in the anti-overflow cooker, meaning fewer bubbles, and there is no risk of overflow. Therefore, the firepower value needs to be lowered. Therefore, if the oxygen content change rate is less than or equal to the oxygen content change rate threshold, the first firepower value remains unchanged.

[0075] An embodiment of the present application provides an anti-overflow control method. During the cooking process of an anti-overflow stove, multiple oxygen levels within the anti-overflow stove, as detected by an oxygen sensor, are acquired. Based on the multiple oxygen levels, a rate of change of the oxygen content within the anti-overflow stove is determined. If the oxygen content rate of change exceeds a threshold oxygen content rate of change, the anti-overflow stove's first power level is reduced according to a preset power adjustment rule. The threshold oxygen content rate of change is the oxygen content at which the anti-overflow stove overflows after cooking for a preset time period. Thus, by monitoring the oxygen content rate of change within the anti-overflow stove, when the oxygen content rate of change exceeds the threshold oxygen content rate of change, the current power level is reduced according to the preset power adjustment rule. This method, based on the characteristics of the anti-overflow stove before overflow, can predict the possibility of overflow and then begin reducing the power level, fundamentally avoiding the possibility of overflow and truly achieving zero overflow.

[0081] The comparison module 503 is configured to reduce the first firepower value of the anti-overflow cooker according to a preset firepower adjustment rule if the oxygen content change rate is greater than an oxygen content change rate threshold. The oxygen content change rate threshold is the oxygen content at which the anti-overflow cooker overflows after cooking for a preset time period according to the oxygen content change rate threshold.

[0082] As an optional implementation manner, the multiple oxygen contents include a first oxygen content and a second oxygen content, and the determining module 502 is specifically configured to:

[0083] The difference between the first oxygen content and the second oxygen content is determined as the oxygen content change rate in the anti-overflow cooker, and the first oxygen content is the oxygen content at the moment corresponding to the second oxygen content after a preset time period.

[0084] As an optional implementation manner, the comparison module 503 is specifically configured to:

[0085] reducing a first firepower value of the anti-overflow cooker to a second firepower value multiplied by a preset proportional coefficient and the first firepower value;

[0086] After cooking for a preset time period according to the second firepower value, determining an updated rate of change of the oxygen content of the anti-overflow cooker;

[0087] If the updated oxygen content change rate is greater than the oxygen content change rate threshold, the second firepower value is reduced to a third firepower value that is the product of the preset proportional coefficient and the second firepower value, and the updated oxygen content change rate in the anti-overflow pot stove is determined until the determined oxygen content change rate of the anti-overflow pot stove is less than or equal to the oxygen content change rate threshold.

[0092] An embodiment of the present application provides an anti-overflow control device. During the cooking process of an anti-overflow stove, the device acquires multiple oxygen levels within the anti-overflow stove as detected by an oxygen sensor. Based on the multiple oxygen levels, the device determines the rate of change of the oxygen content within the anti-overflow stove. If the oxygen content rate of change exceeds a threshold oxygen content rate of change, the device reduces the first power level of the anti-overflow stove according to a preset power adjustment rule. The threshold oxygen content rate of change is the oxygen content at which the anti-overflow stove overflows after cooking for a preset time period at the threshold oxygen content rate of change. Thus, by monitoring the oxygen content rate of change within the anti-overflow stove, when the oxygen content rate of change exceeds the threshold oxygen content rate of change, the device reduces the current power level according to the preset power adjustment rule. This allows the device to determine the possibility of overflow in advance based on the oxygen content rate of change before overflowing, and then reduces the power level, fundamentally avoiding the possibility of overflow and truly achieving zero overflow.
