Description

Technical Field

[0001] This application relates to home appliance technology, and more particularly to an anti-overflow control method, device, and cooking appliance. Background Technology

[0002] Currently, many precision cookware sets have added anti-overflow detection functions. These cookware sets usually have one or more anti-overflow detection probes installed on the pot wall or lid to detect overflow. When foam or liquid in the pot comes into contact with the anti-overflow detection probe, an anti-overflow signal is generated. The microcontroller unit (MCU) then controls the heating to stop for a period of time based on the anti-overflow signal to prevent overflow.

[0003] However, this method of stopping heating for a period of time after the overflow detection probe detects an overflow signal is prone to misjudgment, leading to frequent interruptions in the heating process. Summary of the Invention

[0004] This application provides an anti-overflow control method, device, and cooking appliance that avoids frequent interruptions in the heating process due to misjudgment of anti-overflow detection.

[0005] In a first aspect, this application provides an anti-overflow control method applied to a cooking appliance, the cooking appliance including a pot body and a pot lid, comprising:

[0006] The state of the pot lid is detected, and the pot lid is either open or closed.

[0007] When the lid is detected to be open, the cooking appliance is controlled to stop the overflow detection.

[0008] The overflow detection method detects the state of the pot lid and stops the overflow detection when the lid is open, thereby avoiding false overflow detection when the lid is open, reducing unnecessary overflow detection, preventing frequent interruptions of the cooking process, and improving the user experience.

[0009] In one feasible implementation, controlling the cooking appliance to stop the overflow detection includes:

[0010] If the cooking appliance is in a keep-warm or heating state before the lid is detected to be open, the cooker stops the anti-overflow detection and maintains the state it was in before the lid was opened. Maintaining the cooking state while the lid is open, and simultaneously stopping the anti-overflow detection, ensures the continuity of the cooking process and avoids affecting the cooking effect by preventing the lid from being opened.

[0011] In one feasible implementation, controlling the cooking appliance to stop the overflow detection includes:

[0012] If the cooking appliance is in keep-warm mode before the lid is detected to be open, the anti-overflow detection is stopped, and the appliance is controlled to heat up. This prevents the food temperature from dropping due to the lid being open, resulting in a better user experience.

[0013] In one feasible implementation, controlling the cooking appliance to stop the overflow detection includes:

[0014] If the cooking appliance is in a stopped heating state after an anti-overflow detection before the lid is detected to be open, the appliance is controlled to stop the anti-overflow detection and return to its state before heating was stopped. By promptly restoring the cooking appliance to its original state, the cooking effect and user experience are avoided from being affected by prolonged heating stoppage.

[0015] In one feasible implementation, controlling the cooking appliance to stop the overflow detection includes:

[0016] The overflow detection module of the cooking appliance is controlled to stop acquiring overflow detection data, or the overflow detection data sent by the overflow detection module is discarded.

[0017] In one feasible implementation, the method further includes:

[0018] An anti-overflow detection is initiated after a preset time has elapsed since the lid was detected changing from open to closed, and / or when the lid is closed and the temperature inside the cooking appliance exceeds a preset temperature. This avoids unnecessary anti-overflow detection and reduces energy consumption.

[0019] In one feasible implementation, the cooking appliance is equipped with a temperature measuring device, and the detection of the state of the pot lid includes:

[0020] Collect the temperature signal measured by the temperature measuring device;

[0021] If the temperature signal decreases by more than a first threshold within a preset time, the lid is determined to be in the open state.

[0022] If the temperature signal rises by more than a second threshold within a preset time, the lid is determined to be in a closed state.

[0023] In one feasible implementation, the lid is provided with electrodes, and when the lid is fastened to the pot body, the electrodes are electrically connected to the pot body.

[0024] The detection of the state of the pot lid includes:

[0025] Detect the electrical signal on the electrode;

[0026] If the electrical signal is greater than the third threshold, then the lid is determined to be in a closed state.

[0027] If the electrical signal is not greater than the third threshold, then the lid is determined to be in the open state.

[0028] Secondly, this application provides an anti-overflow control device for use in a cooking appliance, the cooking appliance comprising a pot body and a pot lid, including:

[0029] The detection module is used to detect the state of the pot lid, which is either open or closed.

[0030] The control module is used to control the cooking appliance to stop the anti-overflow detection when the lid is detected to be in the open state.

[0031] In one feasible implementation, the control module is used to:

[0032] If the cooking appliance is in a keep-warm or heating state before the lid is detected to be open, the cooking appliance is controlled to stop the overflow detection and maintain the state before the lid was opened.

[0033] In one feasible implementation, the control module is used to:

[0034] If the cooking appliance is in a keep-warm state before the lid is detected to be open, the cooker is controlled to stop the overflow detection and to start heating.

[0035] In one feasible implementation, the control module is used to:

[0036] If the cooking appliance is in a stopped heating state after an anti-overflow detection before the lid is detected to be in an open state, then the cooking appliance is controlled to stop the anti-overflow detection and return to the state before the heating was stopped.

[0037] In one feasible implementation, the control module is used to:

[0038] The overflow detection module of the cooking appliance is controlled to stop acquiring overflow detection data, or the overflow detection data sent by the overflow detection module is discarded.

[0039] In one feasible implementation, the control module is used to:

[0040] An anti-overflow detection is initiated after a preset time has elapsed since the lid was detected to change from an open state to a closed state, and / or when the lid is closed and the temperature inside the cooking appliance is greater than a preset temperature.

[0042] Collect the temperature signal measured by the temperature measuring device;

[0043] If the temperature signal decreases by more than a first threshold within a preset time, the lid is determined to be in the open state.

[0059] Figure 4 This is a structural diagram of a cooking utensil provided in this application. Detailed Implementation

[0060] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] The anti-overflow control method provided in this application can be applied to cooking appliances with anti-overflow detection functions. These appliances typically employ one or more anti-overflow detection probes on the inner wall of the pot or the lid to achieve this function. The cooking appliance may also include a cooking platform, or heating platform, which can be an integral or separate design from the pot body. For example... Figure 1 A schematic diagram of an anti-overflow detection probe for a cooking appliance provided in this application is shown below. Figure 1 As shown, an anti-overflow detection probe 102 is installed on the inner wall of the pot body 101. When foam or liquid in the pot body 101 comes into contact with the anti-overflow detection probe 102, an anti-overflow signal is triggered, and the cooking platform stops heating.

[0062] The aforementioned anti-overflow method may misjudge situations. For example, users often need to open the pot lid to add ingredients or check the cooking status during cooking. During cooking, water droplets will form on the pot lid and the inner wall of the pot. When the user opens the pot lid, the water droplets on the pot lid or the inner wall of the pot will flow and easily come into contact with the anti-overflow detection probe, thereby triggering the anti-overflow signal. Since the MCU controls to stop heating for a period of time after receiving the anti-overflow signal, it is very easy for the heating to stop as soon as the user opens the pot lid, resulting in a very poor user experience.

[0063] To address the aforementioned issues, this application provides an anti-overflow control method. It considers the possibility that water droplets flowing from the lid or the inner wall of the pot when the lid is opened may cause false overflow detection. Furthermore, considering actual overflow scenarios, it is known that the liquid inside the pot will not overflow when the lid is open. Therefore, performing anti-overflow detection when the lid is open is unnecessary. This method detects the state of the lid and stops the anti-overflow detection when the lid is open, thereby avoiding false overflow detection when the lid is open, preventing interruption of the heating process, and improving the user experience.

[0064] The spill prevention control method provided in this application will now be described in detail through specific embodiments. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0065] Figure 2 This is a flowchart illustrating an anti-overflow control method provided in this application. The executor of this method is the controller of the cooking appliance, such as an MCU. Figure 2 As shown, the spill control method includes:

[0066] S201. Detect the state of the pot lid, which is either open or closed.

[0067] In one implementation, the cooking appliance is equipped with a temperature measuring device. The controller collects the temperature signal measured by the temperature measuring device and determines the state of the lid based on the temperature signal. If the temperature signal drops more than a first threshold within a preset time, the lid is determined to be in the open state. If the temperature signal rises more than a second threshold within a preset time, the lid is determined to be in the closed state.

[0068] This temperature measuring device can be a temperature sensor installed on the lid or inner wall of the pot to measure steam temperature. When the user opens the lid during cooking, the steam temperature drops rapidly within a short time, for example, from 100 degrees Celsius to 80 degrees Celsius. If the lid is then closed, the steam temperature rises rapidly again within a short time, for example, from 80 degrees Celsius back to 100 degrees Celsius. If the lid is left open, the steam temperature may remain at 80 degrees Celsius. Based on this characteristic of steam temperature change, the controller can determine the lid's state based on the detected temperature signal. If the temperature drops significantly within a preset time, it can be determined that the lid is open; if the temperature rises significantly within a preset time, it can be determined that the lid is closed.

[0069] In another implementation, control can determine the state of the lid by detecting the electrical or mechanical connection between the lid assembly and the pot body assembly. For example, electrodes can be used to detect the electrical connection between the lid assembly and the pot body assembly, or a pressure sensor can be used to detect the mechanical connection between the lid assembly and the pot body assembly.

[0070] For example, the cooking appliance uses electromagnetic heating. The lid is equipped with electrodes. When the lid is fastened to the pot body, the electrodes are electrically connected to the pot body, so the controller can detect the electrical signal on the electrodes. The state of the lid is determined based on the magnitude of the electrical signal. If the electrical signal is greater than a third threshold, the lid is determined to be in a closed state; if the electrical signal is not greater than the third threshold, the lid is determined to be in an open state.

[0071] When the lid is closed onto the pot body, the electrodes are electrically connected to the pot body. This allows eddy currents generated during the electromagnetic heating process to be conducted to the electrodes, producing an electrical signal. When the lid is removed, the electrical connection between the electrodes and the pot body is broken, and the electrical signal on the electrodes weakens. Therefore, the state of the lid—open or closed—can be determined based on the magnitude of the electrical signal on the electrodes. In practice, the voltage or current value corresponding to the electrical signal on the electrodes can be detected. For example, a signal detection device can be used to detect the voltage value corresponding to the electrical signal on the electrodes for convenient detection.

[0072] S202. When the lid is detected to be open, control the cooking appliance to stop the overflow detection.

[0073] Foam is only produced when the pot lid is closed and the water is kept boiling at a high temperature, due to the action of the food. For example, when cooking porridge, the starch in the rice increases the viscosity of the water. When steam rises from the bottom of the pot, foam is produced. As the foam gradually accumulates to the lid, it overflows. The higher the heating power, the greater the amount of steam, and the faster the foam is produced. However, foam can only be preserved in extremely hot air. When the lid is opened, the air inside the pot convects with the outside air, causing the temperature of the air inside the pot to drop rapidly, and the foam disappears quickly. Therefore, cooking with the lid open will not cause overflow; overflow is only possible when the lid is closed and the heating power is relatively high.

[0074] Therefore, it is unnecessary to perform anti-overflow detection when the lid is open. Thus, anti-overflow detection should be stopped when the lid is open, and can be activated as needed when the lid is closed.

[0075] It should be noted that the controller can stop the overflow detection of the cooking appliance by controlling the overflow detection module to stop acquiring overflow detection data. For example, the controller can send a stop command to the overflow detection module, instructing the overflow detection module to stop acquiring overflow detection data, which can also reduce the power consumption of the overflow detection module.

[0076] Alternatively, the controller can stop the overflow detection of the cooking appliance, or it can discard the overflow detection data sent by the overflow detection module. In this case, the overflow detection module continues to detect overflow and sends the detected overflow detection data to the controller, but the controller stops processing the overflow detection data and discards it directly after detecting that the lid is open.

[0077] The anti-overflow detection method provided in this embodiment detects the state of the pot lid and stops the anti-overflow detection when the pot lid is open, thereby avoiding false judgments of anti-overflow when the pot lid is open, preventing the cooking process from being interrupted, and improving the user experience.

[0078] The above embodiments describe a method for stopping the overflow detection when the pot lid is open. Building upon this, considering that the cooking appliance may be in different cooking states before the user opens the pot lid, the method of this application, in addition to controlling the cooking appliance to stop the overflow detection, can also perform cooking control based on the cooking state before the pot lid is opened. This will be explained below.

[0079] In one feasible implementation, the cooking appliance is in a keep-warm or heating state before the lid is detected to be open. In this scenario, after the controller detects that the lid is open, it can control the cooker to maintain the state before the lid was open while stopping the anti-overflow detection.

[0080] For example, if a user opens the lid while the cooking appliance is heating according to the porridge-cooking program, the controller will stop the anti-overflow detection and continue heating according to the porridge-cooking program since no overflow will occur after opening the lid, thus preventing the current heating process from being interrupted due to opening the lid. Similarly, if the cooking appliance completes the porridge-cooking program and enters the keep-warm mode, and the user opens the lid at this point, the controller will stop the anti-overflow detection and maintain the keep-warm mode since no overflow will occur after opening the lid, thus preventing the keep-warm process from being interrupted due to opening the lid.

[0081] In another feasible implementation, the cooking appliance is in a keep-warm state before the lid is detected to be open. In this scenario, after the controller detects that the lid is open, it can control the cooking appliance to heat up while stopping the anti-overflow detection.

[0082] For example, after the cooking appliance completes heating according to the porridge cooking program and enters the keep-warm state, the user opens the lid. Since there is no overflow after opening the lid, the controller stops the anti-overflow detection. Furthermore, because the temperature of the food inside the pot will drop after the lid is opened, the controller continues heating while the lid is open to prevent the food from cooling down. Optionally, if the controller detects the lid is closed again, it can control the cooking appliance to return to the keep-warm state.

[0083] In another feasible implementation, the cooking appliance is in a stopped heating state after the anti-overflow detection before the lid is detected to be in an open state. In this scenario, after the controller detects that the lid is in an open state, it controls the cooking appliance to return to the state before the anti-overflow detection is stopped.

[0084] For example, during the heating process of a cooking appliance according to the porridge cooking program, if foam inside the pot comes into contact with the anti-overflow detection probe, the anti-overflow signal is triggered, and the controller stops heating the appliance to prevent overflow. When the user opens the lid, the foam inside the pot quickly disappears, preventing overflow, and the temperature inside the pot also drops. Therefore, the controller can then control the appliance to resume heating, avoiding prolonged heating interruptions that could affect cooking results and user experience.

[0085] The above embodiments have described various implementation methods for the controller to stop the overflow detection when it detects that the lid is in an open state. The following will explain how the controller controls the start of the overflow detection.

[0086] Specifically, the anti-overflow detection is activated after a preset time has elapsed since the lid was detected to change from open to closed, and / or when the lid is closed and the temperature inside the cooking appliance is higher than a preset temperature.

[0087] When the lid immediately changes from open to closed, the foam inside the pot will not accumulate to a level that could overflow within a short period. Therefore, the anti-overflow detection does not need to be activated within a preset time after the lid changes from open to closed. Instead, the anti-overflow detection is activated after the preset time has elapsed. For example, if the preset time is 10 seconds, the controller stops the anti-overflow detection when it detects the lid is open. After the user closes the lid, the controller will only reactivate the anti-overflow detection 10 seconds after the lid changes from open to closed.

[0088] Alternatively, if the temperature inside the pot is low when the lid is closed, overflow will not occur. For example, if the user leaves the lid open for a long time, the temperature inside the pot will drop. When the lid is closed again, the temperature inside the pot needs to rise to a certain level before overflow is possible. Therefore, the anti-overflow detection is only activated when the lid is closed and the temperature is higher than the preset temperature.

[0089] Alternatively, the controller can judge both of the above conditions. If the temperature inside the cooking appliance is higher than the preset temperature after a preset time has elapsed since the lid was detected to change from open to closed, the anti-overflow detection will be activated to avoid unnecessary anti-overflow detection and reduce energy consumption.
