[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with relevant regulations; and the acquisition, storage, processing, transmission, etc. of data must comply with relevant laws and regulations. In the embodiments of this application, some existing solutions in the industry such as certain software, components, models, etc. may be mentioned, and they should be considered as exemplary. Their purpose is only to illustrate the feasibility of the implementation of the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0048] The anti-overflow control device of the rice cooker is an electrical safety device, which is designed to improve the safety and convenience of the cooking process. On the one hand, it can effectively prevent rice or other liquid foods from overflowing during the cooking process, avoid safety hazards such as scalding and fire, and can automatically adjust the heating power and heating time according to the type and quantity of ingredients to achieve intelligent cooking. On the other hand, after using the anti-overflow control device of the rice cooker, the user does not need to pay attention to the cooking process at all times, which improves the convenience of life, and reduces unnecessary energy consumption by accurately controlling the heating time and temperature, achieving energy-saving effects. The rice cooker is a kitchen appliance that uses electric heat to cook food. By converting electrical energy into thermal energy, the food is steamed, boiled, stewed, boiled, and simmered. In the present application, the anti-overflow control device of the rice cooker is arranged in the rice cooker, which is used to realize intelligent anti-overflow in the cooking process of the rice cooker without affecting the cooking effect of the ingredients.

[0049] In some embodiments, after the food boils, the internal pressure of the rice cooker is generally reduced by releasing air to prevent the food from overflowing. However, since the reduced pressure will reduce the boiling point of the food, thereby prolonging the cooking time of the food, the traditional method of preventing the rice cooker from overflowing will affect the cooking efficiency of the food.

[0050] Based on this, Figure 1 As shown, the present application provides an electric rice cooker overflow prevention control device, the device comprising: a foam detection device 10, a pressure sensor 20, a valve 30, and a control device 40 communicatively connected to the foam detection device 10 and the valve 30; the valve 30 is arranged at the air vent of the electric rice cooker; the foam detection device 10 is used to collect the foam height in the electric rice cooker in real time during the heating operation of the electric rice cooker; the control device 40 is used to adjust the heating operation parameters of the electric rice cooker based on the height difference between the foam height and the first height when the foam height is greater than the first height, so as to reduce the heating rate of the electric rice cooker; the pressure sensor 20 is used to collect the internal pressure of the electric rice cooker and the external pressure of the electric rice cooker when the foam height is greater than the second height; the second height is greater than the first height; the control device 40 is also used to control the valve 30 to open when the internal pressure and the external pressure are inconsistent.

[0051] Among them, the foam detection device 10 refers to a device that can detect the height, duration or stability of the foam. In this embodiment, the foam detection device 10 is used to detect the height of the foam in the rice cooker. For example, the foam detection device 10 may include a photoelectric sensor and an ultrasonic module, etc. Exemplarily, the photoelectric sensor works by using the reflection or shielding characteristics of light. When the foam rises to the sensing range of the photoelectric sensor, the foam will directly affect or shield the light emitted from the photoelectric sensor or the light intensity reflected back to the sensor. This characteristic enables the photoelectric sensor to directly detect the existence and height of the foam. The ultrasonic module mainly relies on its penetration and reflection characteristics to work. When detecting foam, the main function of the ultrasonic module is to be able to penetrate the steam environment and directly reach the bottom of the foam for liquid level measurement. It is not easily affected by steam or smoke, and can detect the liquid level height of the liquid in the rice cooker, that is, the initial height of the foam. Therefore, through the coordinated work of the ultrasonic module and the photoelectric sensor, the actual height of the foam can be intelligently detected.

[0052] Pressure sensor 20 is a kind of component that utilizes microsystem structure to convert extraneous pressure into available signal according to certain method.The basic working principle of pressure sensor 20 mainly relies on the deformation of shaft or diaphragm to measure the size of pressure.When external pressure acts on shaft or diaphragm, it can cause its deformation to a certain degree, and by accurately measuring this deformation, the applied pressure value can be determined.In the present embodiment, two pressure sensors 20 can be set, one is arranged at the inside of electric cooker, used to detect the internal pressure of electric cooker, and the other is arranged at the outside of electric cooker, used to detect the external pressure of electric cooker.

[0053] The valve 30 is a device for controlling the flow of fluid (including liquid, gas, powder, etc.). It adjusts the flow rate, pressure and flow direction of the fluid by changing the channel area of ​​the fluid in the pipeline. The valve 30 plays a vital role in the pipeline system and is used to open, close, adjust or control the flow of the fluid, thereby ensuring the normal operation of the pipeline system and the safety and stability of the process. The working principle of the valve 30 is mainly to use the sealing cooperation between the valve flap and the valve seat to achieve the control of the fluid. When the valve flap is driven by the transmission device to move, it will change the size of the gap between the valve seat and the valve seat, thereby changing the channel area of ​​the fluid. When the valve flap is completely closed, the fluid is completely cut off; when the valve flap is partially opened, the fluid can flow through a certain channel area; when the valve flap is fully opened, the fluid channel area reaches the maximum, and the fluid can flow smoothly. In this embodiment, the valve 30 is arranged at the air vent to realize the opening and closing of the air vent. The air vent is used to balance the internal and external pressures.

[0054] The control device 40 is a core part in the device, which is responsible for receiving input signals, executing control algorithms, and generating corresponding output signals to control the operation of the device. In the present embodiment, the control device can be used to adjust the heating operating parameters of the electric cooker, the opening and closing of the control valve 30, etc.

[0055] The foam height refers to the actual height of the foam. For example, in the process of cooking rice porridge in the electric rice cooker, the foam floats on the rice porridge, then the foam height at this time refers to the difference between the bottom of the foam and the highest position of the foam. In the present embodiment, the first height refers to 90% of the preset warning height, that is, a warning height can be preset first, when the foam height reaches the warning height, the height of the surface foam has reached the warning value, and certain measures need to be taken, such as opening the air vents, etc., and when the foam height reaches 90% of the warning height, that is, when it reaches the first height, it means that the foam height is already high, and certain measures can be taken, such as reducing the power of the electric rice cooker or performing intermittent heating, etc. It can be understood that the first height can also be set to other values, which can be determined according to the actual situation. The second height is the preset warning height. In some specific embodiments, the warning height can be 90% or 95% of the height of the electric rice cooker, etc., which is not limited here.

[0056] The heating operating parameter refers to the set of various technical indicators involved in the heating process of the electric cooker. In the present embodiment, the heating operating parameter can be the power of the electric cooker or the heating interval time, etc. The heating rate refers to the degree of temperature rise of an object or a medium in a unit time, which reflects the speed and efficiency of the heating process. The internal pressure refers to the pressure inside the electric cooker, and the external pressure refers to the pressure outside the electric cooker, that is, the pressure of the external environment.

[0057] Specifically, during the cooking process of the rice cooker, no foam will be generated before the ingredients boil. After the ingredients boil and generate foam, the foam height in the rice cooker can be detected by the foam detection device 10, and the foam height is fed back to the control device 40 in real time. The control device 40 compares and judges the foam height and the first height. When the foam height is greater than the first height, the heating working parameters of the rice cooker are adjusted based on the height difference between the foam height and the first height, thereby reducing the heating rate of the rice cooker and reducing the foam generation speed. When the foam height is greater than the second height, the pressure sensor 20 is controlled to collect the internal pressure of the rice cooker and the external pressure of the rice cooker to determine whether the internal pressure and the external pressure are consistent. When the internal pressure and the external pressure are inconsistent, the valve 30 is controlled to be opened, and the air vent provided with the valve 30 can be opened to reduce the internal pressure of the rice cooker.

[0058] In some specific embodiments, the process of adjusting the heating operating parameters of the rice cooker based on the height difference between the foam height and the first height can be to adjust the power of the rice cooker based on the height difference between the foam height and the first height, or to adjust the heating interval time of the rice cooker based on the height difference between the foam height and the first height.

[0059] The above-mentioned electric rice cooker overflow prevention control device is configured with a foam detection device 10 for real-time collection of the foam height in the electric rice cooker during the heating operation of the electric rice cooker, so that the change of the foam can be determined in real time, so as to facilitate timely control of the foam; a control device 40 is configured to adjust the heating operation parameters of the electric rice cooker based on the height difference between the foam height and the first height when the foam height is greater than the first height, so that the heating rate of the electric rice cooker can be adaptively reduced according to the degree of change of the foam, thereby improving the flexibility of the electric rice cooker overflow prevention control process; a pressure sensor 20 is configured to collect the internal pressure of the electric rice cooker and the external pressure of the electric rice cooker when the foam height is greater than the second height, so as to determine the boiling situation inside the electric rice cooker; finally, the control device 40 controls the valve 30 to be opened when the internal pressure and the external pressure are inconsistent, so as to open the air vent provided with the valve 30, thereby reducing the internal pressure of the electric rice cooker and improving the overflow prevention control effect of the electric rice cooker. By adopting the above-mentioned device to perform overflow prevention control of the rice cooker, on the one hand, the heating rate of the rice cooker can be adaptively adjusted according to the degree of change of the foam inside the rice cooker, thereby improving the flexibility of the overflow prevention control process of the rice cooker; on the other hand, when the food in the rice cooker has been boiling, the air vents can be opened to reduce the internal pressure of the rice cooker, thereby ensuring that the food in the rice cooker will not overflow. The combination of the two can ensure the cooking efficiency of the food in the rice cooker while ensuring the overflow prevention control effect of the rice cooker.

[0060] In one embodiment, Figure 2As shown, the electric rice cooker overflow prevention control device further includes a foam intercepting device 50; the foam intercepting device 50 is arranged in the inner pot of the electric rice cooker, and is used to intercept the foam generated in the electric rice cooker.

[0061] The foam interception device 50 is a device specially designed to intercept, collect and process foam. Exemplarily, the foam interception device 50 can be, for example, a foam particle interception device used in an auxiliary device of a foam forming machine, which can adsorb foam particles floating out of a crushing cylinder 360 degrees through a rotating adsorption mechanism, or a foam interception net, which can intercept foam through a smaller porous structure, so that the foam contacts the foam interception net during the floating process and breaks into liquid.

[0062] Specifically, in this embodiment, the foam intercepting device 50 is a foam intercepting net, which is arranged in the inner pot of the rice cooker and can intercept the foam generated in the rice cooker. When the foam floats to the position where the foam intercepting device 50 is set, the foam will contact the foam intercepting net and break into liquid, part of which will directly flow back into the inner pot, and part of which will flow back into the inner pot through the diversion device 60.

[0063] In some specific embodiments, the foam intercepting device 50 can be arranged at the top of the inner pot of the rice cooker or at a higher position in the inner pot. The specific setting can be based on actual conditions and is not limited here.

[0064] In this embodiment, a foam intercepting device 50 is provided in the inner pot of the electric rice cooker, which can effectively intercept the foam and make the foam flow back into the inner pot, thereby playing a certain role in preventing the electric rice cooker from overflowing.

[0065] In one embodiment, Figure 2 As shown, the rice cooker overflow prevention control device further includes a flow guide device 60; the flow guide device 60 is connected to the foam interception device 50 and is disposed around the outside of the inner pot of the rice cooker;

[0066] The flow guiding device 60 is used to guide the liquid formed after the foam bursts back into the inner container.

[0067] The flow guide device 60 refers to a device or component for controlling the direction of water flow or air flow. In this embodiment, the flow guide device 60 can be a flow guide groove, which is connected to the foam interception device 50, surrounded by the inner pot of the rice cooker, and connected to the inner pot. Exemplarily, a one-way valve can be provided at the connection between the flow guide device 60 and the inner pot, so that only the liquid in the flow guide device 60 is allowed to flow into the inner pot.

[0068] Specifically, the guide device 60 is connected to the foam intercepting device 50, and the foam intercepting device 50 can effectively intercept the foam. However, in the process of foam bursting, a part of the liquid formed by the foam bursting can directly return to the inner tank, and a part of the liquid formed by the foam bursting will gush out. This part of the gushing liquid will converge into the guide device 60, and the guide device 60 will guide the flow path of the liquid through its inclined or arc-shaped design, and return the liquid to the inner tank in a smooth manner, ensuring that the liquid can flow back smoothly along the predetermined path without overflowing or excessive foam again.

[0069] In this embodiment, a guide device 60 is arranged around the outside of the inner pot of the rice cooker, which can add another layer of protection on the basis of the foam interception device 50 intercepting the foam, so that the foam not intercepted by the foam interception device 50 will not overflow to the outer wall of the inner pot of the rice cooker, thereby improving the anti-overflow effect of the rice cooker.

[0070] In one embodiment, Figure 3 As shown, the rice cooker overflow prevention control device also includes a motor device 70; the motor device 70 is used to drive the flow guide device 60 to rotate.

[0071] The motor device 70 refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction, and its core function is to realize the conversion or transmission of electric energy, including the conversion of mechanical energy into electric energy, the conversion of electric energy into mechanical energy, and the conversion of electric energy into each other. In this embodiment, the motor device 70 is used to drive the flow guide device 60 to rotate.

[0072] Specifically, the electric rice cooker overflow prevention control device is also provided with a motor device 70 for driving the flow guide device 60 to rotate, which can realize the cleaning function of the electric rice cooker or the function of accelerating the foam rupture. In a specific embodiment, there is an interlayer between the flow guide device 60 and the inner pot, and the flow guide device 60 and the interlayer have a connecting port. During the rotation of the flow guide device 60, the interlayer can be cleaned by the liquid in the flow guide device 60, and then the cleaned sewage can be discharged to the outside of the electric rice cooker. In another specific embodiment, during the process of the motor device 70 driving the flow guide device 60 to rotate, the inner pot will also rotate accordingly. During the rotation of the inner pot, the foam will collide with the foam interception device 50 and the inner wall of the inner pot, and the foam will also break and disappear.

[0073] In this embodiment, a motor device 70 is provided for driving the flow guide device 60 to rotate. On the one hand, the self-cleaning ability of the rice cooker can be improved, and on the other hand, the speed of foam bursting in the rice cooker can be accelerated.

[0074] In one embodiment, Figure 3 As shown, the electric rice cooker overflow prevention control device further includes a liquid level detection device 80; the liquid level detection device 80 is used to determine the liquid level height in the electric rice cooker.

[0075] The liquid level detection device 80 is a device for measuring and monitoring the level or height of a liquid. For example, the liquid level detection device 80 may be a liquid level sensor, etc., which detects the liquid level by emitting ultrasonic waves and detecting the liquid level by the difference in the reflection and reception time of the ultrasonic waves to water or other media.

[0076] Specifically, the liquid level detection device 80 can be used to determine the liquid level height in the rice cooker, and the control device 40 can also adjust the heating working parameters of the rice cooker according to the liquid level height adaptability. For example, when the height difference between the foam height and the first height is 5 cm, the boiling degree of the food with a lower liquid level height is higher than that of the food with a normal liquid level height under the same height difference. Therefore, the power adjustment of the food with a lower liquid level height corresponding to the rice cooker is lower, the heating time adjustment in the heating interval is less, and the heating pause time adjustment is more. Similarly, when the boiling degree of the food with a higher liquid level height is 5 cm, the boiling degree of the food with a normal liquid level height under the same height difference is lower, therefore, the power adjustment of the food with a higher liquid level height corresponding to the rice cooker is slightly higher, the heating time adjustment in the heating interval is more, and the heating pause time adjustment is less.

[0077] For example, the liquid level detection device 80 can also detect the height of the water level and the amount of rice respectively according to the different time differences between the reflection and reception of the ultrasonic wave on the water and the rice, and then set the heating curve corresponding to different heating moments according to the height ratio of the water level and the amount of rice at different moments. The heating working parameters are adaptively adjusted according to different heating curves.

[0078] In this embodiment, a liquid level detection device 80 capable of detecting the liquid level height is provided to determine the liquid level height, and the heating working parameters of the rice cooker are dynamically adjusted based on the liquid level height, thereby improving the accuracy of the rice cooker's overflow prevention control.

[0079] In one embodiment, Figure 4 As shown, a method for preventing overflow of an electric rice cooker is also provided, which is applied to the device for preventing overflow of an electric rice cooker in any of the above embodiments, and the method comprises:

[0080] Step S402, during the heating process of the rice cooker, the foam height in the rice cooker is collected in real time.

[0081] The heating work of the rice cooker refers to the working process of the rice cooker cooking the ingredients, which requires heating the ingredients. The foam height refers to the actual height of the foam. For example, when the rice cooker is cooking rice porridge, the foam floats on the rice porridge. The foam height at this time refers to the difference between the bottom of the foam and the highest position of the foam.

[0082] Specifically, during the heating process of the rice cooker, the foam height in the rice cooker is collected in real time, and the real-time generation of foam in the rice cooker can be determined so that certain defoaming measures can be taken later. Exemplarily, the process of collecting the foam height in the rice cooker can be actively obtained or passively received.

[0083] Step S404: When the foam height is greater than the first height, based on the height difference between the foam height and the first height, adjusting the heating operating parameters of the rice cooker to reduce the heating rate of the rice cooker.

[0084] Wherein, the foam height refers to the actual height of the foam. For example, in the process of cooking rice porridge with an electric rice cooker, the foam floats on the rice porridge, then the foam height at this time refers to the difference between the bottom of the foam and the highest position of the foam. In this embodiment, the first height refers to 90% of the preset warning height, that is, a warning height can be preset first, when the foam height reaches the warning height, the height of the surface foam has reached the warning value, and certain measures need to be taken, such as opening the vents, etc., and when the foam height reaches 90% of the warning height, that is, when it reaches the first height, it means that the foam height is already high, and certain measures can be taken, such as reducing the power of the electric rice cooker or performing intermittent heating, etc. It can be understood that the first height can also be set to other values, which can be determined according to actual conditions. The heating working parameter refers to a collection of various technical indicators involved in the heating process of the electric rice cooker. In this embodiment, the heating working parameter can be the power of the electric rice cooker or the heating interval time, etc. The heating rate refers to the degree of temperature increase of an object or medium per unit time, which reflects the speed and efficiency of the heating process.

[0085] Specifically, the foam height and the first height can be compared and judged. When the foam height is greater than the first height, it is considered that the foam height is already high and corresponding measures can be taken. That is, the heating operating parameters of the rice cooker can be adjusted based on the height difference between the foam height and the first height, thereby reducing the heating rate of the rice cooker and reducing the speed of foam generation.

[0086] In some specific embodiments, the process of adjusting the heating operating parameters of the rice cooker based on the height difference between the foam height and the first height can be to adjust the power of the rice cooker based on the height difference between the foam height and the first height, or to adjust the heating interval time of the rice cooker based on the height difference between the foam height and the first height.

[0087] Step S406: when the foam height is greater than the second height, obtaining the internal pressure of the rice cooker and the external pressure of the rice cooker collected by the pressure sensor.

[0088] Wherein, the second height is greater than the first height. The second height is a preset warning height. In some specific embodiments, the warning height can be 90% or 95% of the height of the rice cooker, etc., which is not limited here. The internal pressure refers to the pressure inside the rice cooker, and the external pressure refers to the pressure outside the rice cooker, that is, the pressure of the external environment.

[0089] Specifically, when the foam height is greater than the second height, it means that the foam has reached the warning height, and therefore, the next measure needs to be taken, that is, the internal pressure of the rice cooker and the external pressure of the rice cooker collected by the pressure sensor need to be obtained to determine the boiling condition of the food in the rice cooker. Exemplarily, the process of obtaining the internal pressure of the rice cooker and the external pressure of the rice cooker collected by the pressure sensor can be actively obtained or passively received.

[0090] Step S408, when the internal pressure is inconsistent with the external pressure, control the valve to open.

[0091] Specifically, when the internal pressure is inconsistent with the external pressure, it means that the food in the rice cooker has boiled. Therefore, the valve can be controlled to open, and the air vent provided with the valve can be opened to reduce the internal pressure of the rice cooker.

[0092] The above-mentioned electric rice cooker overflow prevention control method collects the foam height in the electric rice cooker in real time during the heating operation of the electric rice cooker, and can determine the change of the foam in real time, so as to facilitate timely control of the foam. When the foam height is greater than the first height, the heating operation parameters of the electric rice cooker are adjusted based on the height difference between the foam height and the first height, and the heating rate of the electric rice cooker can be adaptively reduced according to the degree of change of the foam, thereby improving the flexibility of the electric rice cooker overflow prevention control process. When the foam height is greater than the second height, the internal pressure of the electric rice cooker and the external pressure of the electric rice cooker are collected, and the boiling situation inside the electric rice cooker can be determined. When the internal pressure and the external pressure are inconsistent, the valve is controlled to be opened, so as to reduce the internal pressure of the electric rice cooker and improve the overflow prevention control effect of the electric rice cooker. By adopting the above method to control the overflow prevention of the rice cooker, on the one hand, the heating rate of the rice cooker can be adaptively adjusted according to the degree of change of the foam inside the rice cooker, thereby improving the flexibility of the overflow prevention control process of the rice cooker; on the other hand, when the food in the rice cooker has boiled, the valve can be controlled to open to reduce the internal pressure of the rice cooker, thereby ensuring that the food in the rice cooker will not overflow. The combination of the two can ensure the cooking efficiency of the food in the rice cooker while ensuring the overflow prevention control effect of the rice cooker.

[0093] In one embodiment, Figure 5 As shown, the heating working parameters include power; based on the height difference between the foam height and the first height, the heating working parameters of the rice cooker are adjusted, including:

[0094] Step S502, obtaining the correlation between the power step length and the height difference of the rice cooker.

[0095] Step S504: Map the height difference to the correlation between the power step and the height difference, and adjust the power of the rice cooker based on the power step corresponding to the height difference.

[0096] The power step length of the rice cooker refers to a preset value for adjusting the power, for example, 5W, 10W, etc. In the present embodiment, the power step length may vary with the change of the height difference, and the correlation between the power step length and the height difference may be preset, for example, when the height difference is 5cm, the power step length may be 5W, and when the height difference is 10cm, the power step length may be 10W.

[0097] Specifically, the correlation between the power step length and the height difference of the electric cooker can be obtained, and the variation of the power step length of the electric cooker with the height difference can be determined. After that, the height difference determined in real time is mapped to the relationship, and the power step length corresponding to the height difference can be determined, and the power of the electric cooker can be adjusted based on the power step length. For example, the height difference determined in real time is 5cm, and the height difference is mapped to the correlation between the above-mentioned power step length and the height difference, and the corresponding power step length can be determined to be 5w, so the power of the electric cooker can be reduced by 5w.

[0098] In this embodiment, by presetting the correlation between the power step and the height difference, the power adaptability of the rice cooker can be adjusted based on the difference between the foam height and the first height, thereby ensuring the cooking efficiency of food in the rice cooker.

[0099] In one embodiment, Figure 6 As shown, the heating working parameters include a working cycle; based on the height difference between the foam height and the first height, the heating working parameters of the rice cooker are adjusted, including:

[0100] Step S602, obtaining the correlation between the working cycle of the rice cooker and the height difference.

[0101] Step S604: Map the height difference to the correlation between the working cycle and the height difference, and adjust the rice cooker based on the working cycle corresponding to the height difference.

[0102] Among them, the working cycle of the rice cooker refers to the regular cycle of the rice cooker working, for example, it can be turned on for 5 minutes and turned off for 5 minutes, or turned on for 5 minutes and turned off for 10 minutes, or turned on for 10 minutes and turned off for 10 minutes, etc. In this embodiment, the working cycle can change with the change of the height difference, and the correlation between the working cycle and the height difference can be preset, for example, if the height difference is 5 cm, the working cycle can be turned on for 5 minutes and turned off for 5 minutes, and if the height difference is 10 cm, the working cycle can be turned on for 5 minutes and turned off for 10 minutes.

[0103] Specifically, the correlation between the duty cycle of the electric cooker and the height difference can be obtained, the variation of the duty cycle of the electric cooker with the height difference is determined, and then the height difference determined in real time is mapped to the relationship, and the duty cycle corresponding to the height difference can be determined, and the electric cooker can be adjusted based on the duty cycle. For example, the height difference determined in real time is 5cm, and the height difference is mapped to the correlation between the above-mentioned duty cycle and the height difference, and the corresponding duty cycle can be determined to be closed for 5 minutes, or opened for 5 minutes, so the electric cooker can be adjusted according to the duty cycle. Exemplary, the closing duration or opening duration of the electric cooker can also be adjusted according to the height difference, and the specific implementation rules are similar to the above-mentioned method, which will not be repeated here.

[0104] In this embodiment, by presetting the correlation between the working cycle and the height difference, the working cycle of the rice cooker can be adaptively adjusted based on the difference between the foam height and the first height, thereby ensuring the cooking efficiency of food in the rice cooker.

[0105] In a specific embodiment, Figure 7 As shown, a method for preventing overflow of an electric rice cooker is also provided, comprising:

[0106] Step S701, during the heating process of the rice cooker, collecting the foam height in the rice cooker in real time;

[0107] Step S702, when the foam height is greater than the first height;

[0108] Step S703, obtaining the correlation between the power step length and the height difference of the rice cooker;

[0109] Step S704, mapping the height difference to the correlation between the power step and the height difference, and adjusting the power of the rice cooker based on the power step corresponding to the height difference;

[0110] Step S705, obtaining the correlation between the working cycle of the rice cooker and the height difference;

[0111] Step S706, mapping the height difference to the correlation between the working cycle and the height difference, and adjusting the rice cooker based on the working cycle corresponding to the height difference;

[0112] Step S707, when the foam height is greater than the second height, obtaining the internal pressure of the rice cooker and the external pressure of the rice cooker collected by the pressure sensor;

[0113] wherein the second height is greater than the first height;

[0114] Step S708, when the internal pressure is inconsistent with the external pressure, control the valve to open.

[0115] In one embodiment, if Figure 8 As shown, a method for preventing overflow of an electric rice cooker is also provided, comprising:

[0116] Step S801, the electric rice cooker starts working. The user starts the electric rice cooker to cook porridge or beans, and the system enters the preheating stage.

[0117] Step S802: The liquid level sensor detects the water level and the amount of rice. The ratio of water to rice is analyzed, and different heating curves are set according to different rice-water ratios. In the initial stage of heating: rapid heating to boiling, no anti-overflow operation is performed at this time.

[0118] Step S803, foam height detection: After the electric cooker boils, an ultrasonic module and a photoelectric sensor detection module are installed on the inner wall of the electric cooker to detect the height of the foam inside the electric cooker.

[0119] Step S804, determine whether the foam height reaches the first height. Set a warning height A (second height) to determine whether the foam height reaches the warning height. If the foam height does not reach 90% of the warning height A (first height), the rice cooker continues to work at the previous power and returns to step S803; if the foam height reaches 90% of the warning height A, enter step S805 to adjust the heating mode. Reduce the heating power and perform intermittent heating. The rice cooker heats for a period of time and then stops for a period of time.

[0120] Step S806, detecting the foam height again.

[0121] Step S807, judging whether the foam height reaches the second height. The system continues to perform foam detection to detect whether the foam height inside the rice cooker reaches the warning height A. If the foam height does not reach the warning height A, the rice cooker works according to the adjusted mode and returns to step S806; if the foam height reaches the warning height A, the pressure sensor on the rice cooker cover is activated and step S808 is performed to detect the internal pressure and external pressure of the rice cooker.

[0122] Step S809, when the internal pressure is inconsistent with the external pressure, control the valve to open.

[0123] At the same time, the foam collection net combined with the guide groove in the inner pot can effectively intercept and guide the foam backflow to prevent overflow to the outside. Then the rice cooker continues to reduce the heating power until cooking is completed, and finally the rice cooker keeps warm.

[0124] In addition, once the rice cooker has a slight overflow, the inner wall cleaning and drying program will be automatically started to keep the inside of the rice cooker clean and reduce the user's cleaning burden. The rice cooker will also activate an intelligent alarm to remind the user so that the user can quickly deal with it and ensure the safety of the rice cooker.
