Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a method, device, equipment and storage medium for preventing overflow of cooking equipment. Background Technology

[0002] Currently in the home appliance industry, many cooking products are prone to overflowing during cooking modes such as porridge and soup. Therefore, anti-overflow functions are urgently needed for these cooking products. Taking food processors as an example, they are divided into single-item and integrated types, with single-item types being the mainstream. Integrated types integrate the food processor module into other products, such as placing the food processor in the cabinet under an integrated stove. The food processor is heated by a heating module and stirred and blended by a motor. When cooking with the food processor (stewing, making soy milk, making juice, etc.), foam is produced. The continuously generated foam can overflow onto the circuit board at the bottom of the cup, causing a short circuit and damaging the product.

[0003] In the current technology, most food processors are countertop machines without anti-overflow function; while the motors of soy milk makers and high-speed blenders with anti-overflow function are placed on the lid, making it difficult to achieve a good anti-overflow effect. Summary of the Invention

[0023] If both the first detection interface and the second detection interface detect the pot lid signal, then it is determined that the pot lid is properly closed.

[0024] With the pot lid closed, the actual values ​​of the anti-overflow parameters are collected using the first detection interface and the second detection interface.

[0025] According to another aspect of the present invention, an anti-overflow device for a cooking apparatus is provided, comprising:

[0026] The overflow prevention parameter threshold determination module is used to determine the target overflow prevention parameter threshold based on the current cooking mode and the current cooking scenario;

[0027] The current motor speed and current temperature change curve acquisition module is used to acquire the current motor speed and current temperature change curve of the cooking equipment when the cooking equipment is in the start state;

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0058] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0059] Example 1

[0060] Figure 1 This is a flowchart illustrating an anti-overflow method for a cooking device according to Embodiment 1 of the present invention. The cooking device includes equipment such as a food processor, a stir-fry machine, and a soy milk maker. This embodiment describes the use of a food processor for cooking. The method can be executed by an anti-overflow device of the cooking device, which can be implemented in hardware and / or software. The anti-overflow device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0061] S110. Determine the target overflow prevention parameter threshold based on the current cooking mode and the current cooking scenario.

[0062] The current cooking mode and current cooking scenario can be automatically matched based on the type and amount of ingredients added to the cooking equipment, or they can be set by the user, using the user-selected cooking mode and scenario as the current cooking mode and scenario. For example, the cooking mode can be high-heat stewing, low-heat simmering, etc., and the cooking scenario can be making soy milk, porridge, milk, etc. The anti-overflow parameter is a data acquisition parameter used for anti-overflow control of the cooking equipment, which can be one or more of voltage analog signals, speed signals, and temperature signals. The target anti-overflow parameter threshold is the threshold of the specific anti-overflow parameter that matches the current cooking mode and current cooking scenario.

[0063] During cooking, different types of ingredients have different abilities to cause liquid to overflow when the amount of ingredients is the same, and the same type of ingredients also have different abilities to cause liquid to overflow when the amount of ingredients is different. Therefore, the cooking mode and cooking scenario that match the type and amount of ingredients can be determined. Then, the target anti-overflow parameter threshold can be determined based on the current cooking mode and current cooking scenario, so as to better avoid the phenomenon of overflow of cooking equipment during cooking.

[0064] Preferably, the type and quantity of ingredients can be determined by the identification device on the cooking equipment, or the user can send the information about the type and quantity of ingredients to the cooking equipment.

[0065] S120. When the cooking equipment is in the start-up state, obtain the current motor speed and current temperature change curve of the cooking equipment.

[0066] The cooking equipment can be a food processor, a stir-fry machine, a soy milk maker, etc. Taking a food processor as an example, it is an appliance that integrates multiple functions such as making soy milk, grinding dry powders, juicing, mincing meat, and shaved ice. The current motor speed of the cooking equipment is the current actual speed of the motor module, and the current temperature change curve is the current temperature change of the heating module. When the cooking equipment is in the start-up state, the motor module and / or heating module are working.

[0067] In this embodiment, after the user starts the cooking device, if the cooking device enters the start state and the motor and / or heating module starts working, the current motor speed and current temperature change curve of the cooking device can be collected in real time. When the motor speed and temperature change meet the set conditions, the anti-overflow function of the cooking device can be triggered.

[0068] Furthermore, the cooking equipment can also have an overload protection function, which prevents the cooking equipment from starting when the weight of the food placed in the cooking equipment exceeds a certain threshold.

[0069] Specifically, the cooking device's food container can have a weighing function, capable of measuring the weight of the added ingredients and water. Preferably, the cooking device can provide multiple cooking modes, each with different weight thresholds. For example, in soy milk mode, the user is allowed to add a total of m grams of ingredients. The food container weighs the added ingredients to a total of M grams. When M > k·m, the user is prompted to remove some ingredients if too much has been added. Here, k is a constant that can be set to be greater than 1.

[0070] S130. If the current motor speed and the current temperature change curve meet the overflow prevention triggering conditions, the actual value of the overflow prevention parameter is collected, and the current overflow status is determined according to the target overflow prevention parameter threshold and the actual value of the overflow prevention parameter.

[0071] The current overflow status includes overflow and no overflow. The overflow prevention parameter is used to determine the current overflow status of the cooking equipment. The actual value of the overflow prevention parameter and the target overflow prevention parameter threshold are the actual collected overflow prevention parameter value and the preset threshold of the overflow prevention parameter, respectively.

[0072] Optionally, the anti-overflow trigger condition can be: the current motor speed is lower than the set speed threshold and the current temperature change curve is in a stable or rising state.

[0073] In this embodiment, to avoid misjudging the current overflow state of the cooking device, an anti-overflow trigger condition can be preset. When the condition is met, the current overflow state is determined based on the actual value of the anti-overflow parameter and the target anti-overflow parameter threshold.

[0074] Specifically, when the motor of the cooking device is stirring the food, if the speed is too high, exceeding the set speed threshold, it may cause the liquid to splash onto the lid. In this case, the interface on the lid that detects the anti-overflow parameter cannot accurately collect the actual value of the anti-overflow parameter, therefore, no determination of the current overflow state is made. Furthermore, the temperature change curve of the cooking device includes several states: stable, rising, and falling. The stable and rising states indicate that the heating module of the cooking device is operating, while the falling state indicates that the heating module has stopped working, and no determination of the current overflow state is needed. Preferably, the anti-overflow function of the cooking device can be triggered when the current motor speed is below the set speed threshold and the current temperature change curve is in a stable or rising state.

[0075] Furthermore, when the anti-overflow function is triggered, the actual value of the anti-overflow parameter can be collected, and the cooking equipment can be judged as to whether an overflow has occurred based on the relationship between the actual value of the anti-overflow parameter and the target anti-overflow parameter threshold.

[0076] Optionally, the overflow prevention parameter can be one or more of a voltage analog signal, a speed signal, and a temperature signal. For example, if a voltage analog signal is used as the overflow prevention parameter, the current overflow state can be determined as overflow when the actual value of the collected voltage analog signal is lower than the voltage analog signal threshold under the current cooking device status.

[0077] S140. If the current overflow status is overflow, the cooking device will enter the stop state until the current overflow status is non-overflow, and then the cooking device will be restarted.

[0078] In this embodiment, when an overflow is detected, the motor module and heating module of the cooking device can be shut down, causing the cooking device to enter a shutdown state.

[0079] Preferably, after the cooking equipment enters the shutdown state, the actual value of the anti-overflow parameter can be collected again after a set time delay. The actual value of the anti-overflow parameter is judged according to the target anti-overflow parameter threshold. If it is normal, the motor module and heating module of the cooking equipment are restarted, and the motor and heating power are reduced at the same time. Otherwise, the set time delay is waited, and the collection of the actual value of the anti-overflow parameter and the judgment of the current overflow status are returned to normal until the actual value of the anti-overflow parameter returns to normal.

[0080] Figure 2This is a schematic diagram of an anti-overflow process provided by an embodiment of the present invention. As shown in the figure, when the start switch of the cooking equipment is enabled, in the start state of the equipment, if the current motor speed and the current temperature change curve meet the anti-overflow trigger condition, the overflow state is judged by the actual value of the anti-overflow parameter and the target anti-overflow parameter threshold. If overflow occurs, the cooking equipment is stopped; if no overflow occurs, the overflow state is judged again after a set time, until the cooking equipment's working timer ends. After the cooking equipment stops, the current overflow state is judged after a set time. If overflow occurs, the cooking equipment remains stopped, and the judgment is made again after the set time. If no overflow occurs, the cooking equipment is started at a lower motor speed and heating power.

[0081] Furthermore, before obtaining the current motor speed and current temperature change curve of the cooking equipment, you can also: perform a lid matching test according to the detection interface on the lid of the cooking equipment; if the lid matching test passes, then enable the start switch of the cooking equipment.

[0082] In this embodiment, before starting the cooking device, a lid matching test can be performed on the pot lid. If the lid matching test passes, it means that the pot lid is properly closed, and the start switch of the cooking device is enabled. In other words, the cooking device is only allowed to start after the pot lid is properly closed; otherwise, even if the user presses the switch of the cooking device, the motor module and heating module of the cooking device will not operate.

[0083] Optionally, the detection interface includes a first detection interface and a second detection interface. The method for detecting the pot lid matching based on the detection interface on the pot lid of the cooking device can be as follows: if both the first detection interface and the second detection interface detect the pot lid signal, then it is determined that the pot lid is properly closed; when the pot lid is properly closed, the actual values ​​of the anti-overflow parameters are collected using the first detection interface and the second detection interface.

[0084] Specifically, the first and second detection interfaces are located on the edge of the pot body and can be used for multiplexing two functions: lid matching detection and actual value acquisition of anti-overflow parameters. These two functions can be switched by opening and closing a relay. For example, when the relay is closed, the detection interface performs the lid matching detection function, detecting the lid signal. If both detection interfaces detect the lid signal, it is determined that the lid is properly closed; otherwise, it is considered that the lid is not properly closed or that there is no lid. After determining that the lid is properly closed, the relay can be disconnected, allowing the detection interface to perform the actual value acquisition function of the anti-overflow parameters. Preferably, the detection interface can acquire analog voltage signals.

[0085] Figure 3This is a schematic diagram of the structure of a cooking device provided in this embodiment. As shown in the figure, the first detection interface and the second detection interface are located at opposite ends of the edge of the pot body. A metal plate is provided around the outer edge of the pot lid. When both detection interfaces detect the lid signal, it indicates that the lid is properly closed. The metal plate on the lid is connected to the anti-overflow detection point in the center of the lid via a conductor. After the anti-overflow function is triggered, when overflow occurs, the contents of the cooking device are connected to the conductor through the anti-overflow detection point, and the detection interface can collect a voltage analog signal. Additionally, a plastic needle is provided on the lid for puncturing foam.

[0086] The overflow prevention method for cooking equipment disclosed in this invention first determines a target overflow prevention parameter threshold based on the current cooking mode and scenario. Then, while the cooking equipment is running, it acquires the current motor speed and temperature change curves. If these curves meet the overflow triggering conditions, the target overflow prevention parameter threshold is determined, and the actual overflow parameter value is collected. The current overflow state is then determined based on the target overflow prevention parameter threshold and the actual overflow parameter value. The current overflow state includes overflow and non-overflow. If the current overflow state is overflow, the cooking equipment is shut down until the current overflow state changes to non-overflow, at which point the cooking equipment is restarted. This overflow prevention method, under the condition of meeting the overflow triggering conditions, judges the current overflow state through overflow prevention parameters and promptly shuts down the equipment upon overflow, improving the safety and convenience of using the cooking equipment.

[0087] Example 2

[0088] Figure 4 This is a flowchart illustrating an anti-overflow method for a cooking device according to Embodiment 2 of the present invention. This embodiment is a refinement of the above embodiment. Figure 4 As shown, the method includes:

[0089] S210. Obtain the current cooking mode and current cooking scenario of the cooking equipment. Based on the current cooking mode and current cooking scenario, and in conjunction with the preset cooking mode, cooking scenario and anti-overflow parameter threshold comparison table, determine the anti-overflow parameter threshold corresponding to the current cooking mode and current cooking scenario as the target anti-overflow parameter threshold.

[0090] In this embodiment, the current cooking mode can be the current operating mode of the cooking device, such as high-heat stewing, low-heat simmering, intelligent PID mode, chef mode, etc.; the current cooking scenario can be the type of contents added by the user, such as soy milk, porridge, milk, mung bean soup, juice (watermelon, apple, etc.), cleaning, etc. The current cooking mode and current cooking scenario can be automatically matched by the cooking device based on the type and amount of ingredients added to the device, or they can be directly received from the user's settings, using the user-selected cooking mode and scenario as the current cooking mode and scenario.

[0091] Preferably, depending on the current cooking mode and cooking scenario, some cooking modes and scenarios are prone to overflow, while others are not. Therefore, the threshold of the anti-overflow parameter can also be different.

[0092] Based on the current cooking mode and cooking scenario, and combined with the preset cooking mode, cooking scenario and anti-overflow parameter threshold comparison table, the anti-overflow parameter threshold corresponding to the current cooking mode and cooking scenario is determined as the target anti-overflow parameter threshold.

[0093] The preset cooking mode, cooking scenario and anti-overflow parameter threshold comparison table can be stored in the cooking device. When the current cooking mode and current cooking scenario are determined, the applicable threshold value can be extracted from the comparison table as the target anti-overflow parameter threshold by looking up the table.

[0094] Preferably, the table comparing cooking modes, cooking scenarios, and spill prevention parameter thresholds can be as follows:

[0095]

[0096]

[0097] Here, the AD threshold refers to the voltage analog signal threshold, denoted by α; the speed threshold refers to the motor module speed threshold, denoted by m; and the temperature threshold refers to the temperature threshold of the contents of the cooking equipment, denoted by t. The voltage analog signal, motor module speed, and temperature of the contents of the cooking equipment can all be used as overflow prevention parameters.

[0098] Furthermore, after determining the overflow prevention parameter threshold corresponding to the current cooking mode and the current cooking scenario as the target overflow prevention parameter threshold, it is also possible to: correct the target overflow prevention parameter threshold.

[0099] In this embodiment, after determining the target overflow parameter threshold for each overflow parameter according to the cooking mode, cooking scene and overflow parameter threshold comparison table pre-stored in the cooking device, considering the possibility that some special scenarios may not be covered, as well as the possibility that the lid conductor is blocked by dirt, individual differences in the hardware structure of the device, etc., a local automatic calibration function for the target overflow parameter threshold can be added.

[0100] Optionally, the method for correcting the target overflow prevention parameter threshold can be: reporting the address information of the cooking equipment to the cloud platform; receiving the cloud overflow prevention parameter threshold fed back by the cloud platform, and determining the cloud overflow prevention parameter as the target overflow prevention parameter threshold.

[0101] Specifically, due to differences in altitude, air pressure, and boiling point across the country, the overflow situation of cooking equipment in different locations will vary, and therefore the threshold values ​​for anti-overflow parameters will also differ.

[0102] Cooking equipment can access the internet via a network module (Wi-Fi, NB-IoT, 4G, etc.) and report its communication address to the cloud platform. Upon receiving the communication address, the cloud platform converts it into a regional address, thus determining the specific address information of the cooking equipment. The cloud platform maintains a lookup table of overflow prevention parameter thresholds and addresses in its database. It then retrieves the parameter threshold for the corresponding region by looking up the table and sends it to the device (the cooking equipment) via the network. After receiving the parameter threshold from the cloud platform, the cooking equipment can determine its current overflow status according to the new overflow prevention parameter threshold.

[0103] Furthermore, during the operation of the cooking equipment, data such as the motor parameters, heating power, cooking scene, cooking mode, temperature curve, and AD value of the current equipment can be uploaded to the cloud in real time. The cloud platform can build a database to store various equipment data and perform data analysis based on the various data uploaded by the equipment to perform remote diagnosis, so as to avoid the situation where the cooking equipment overflows during normal cooking but the program fails to detect it.

[0104] S220. When the cooking equipment is in the start-up state, obtain the current motor speed and current temperature change curve of the cooking equipment.

[0105] In this embodiment, after the user starts the cooking device, if the cooking device enters the start state and the motor and / or heating module starts working, the current motor speed and current temperature change curve of the cooking device can be collected in real time. When the motor speed and temperature change meet the set conditions, the anti-overflow function of the cooking device can be triggered.

[0106] S230. If the current motor speed and the current temperature change curve meet the overflow prevention triggering conditions, the actual value of the overflow prevention parameter is collected, and the current overflow status is determined according to the target overflow prevention parameter threshold and the actual value of the overflow prevention parameter.

[0107] The current overflow status includes overflow and non-overflow.

[0108] In this embodiment, the overflow prevention parameters can be a voltage analog signal, motor module speed, and the temperature of the contents of the cooking device. Whether the cooking device has overflowed is determined based on the relationship between the actual value of the overflow prevention parameter and the target overflow prevention parameter threshold. For example, if the voltage analog signal is used as the overflow prevention parameter, the current overflow state can be determined as overflow when the actual value of the collected voltage analog signal is lower than the voltage analog signal threshold.

[0109] Optionally, the anti-overflow trigger condition can be: the current motor speed is lower than the set speed threshold and the current temperature change curve is in a stable or rising state.

[0110] In this embodiment, to avoid misjudging the current overflow state of the cooking device, an anti-overflow trigger condition can be preset. When the condition is met, the current overflow state is determined based on the actual value of the anti-overflow parameter and the target anti-overflow parameter threshold.

[0111] S240. If the current overflow status is overflow, the cooking device will enter the stop state until the current overflow status is non-overflow, and then the cooking device will be restarted.

[0112] In this embodiment, when an overflow is detected, the motor module and heating module of the cooking device can be shut down, causing the cooking device to enter a shutdown state.

[0113] Preferably, after the cooking equipment enters the shutdown state, the actual value of the anti-overflow parameter can be collected again after a set time delay. The actual value of the anti-overflow parameter is judged according to the target anti-overflow parameter threshold. If it is normal, the motor module and heating module of the cooking equipment are restarted, and the motor and heating power are reduced at the same time. Otherwise, the set time delay is waited, and the collection of the actual value of the anti-overflow parameter and the judgment of the current overflow status are returned to normal until the actual value of the anti-overflow parameter returns to normal.

[0114] The overflow prevention method for cooking equipment disclosed in this invention determines the current overflow state based on overflow prevention parameters when the overflow trigger condition is met. Furthermore, the cooking mode and cooking scenario of the cooking equipment are considered when determining the target overflow prevention parameter threshold, making the judgment of the overflow state of the cooking equipment more accurate. In addition, the cooking equipment provided in this embodiment can also interact with a cloud platform, and the local parameter thresholds of the cooking equipment can be corrected according to the cloud platform, further improving the security of the cooking equipment.

[0116] Figure 5 This is a schematic diagram of the anti-overflow device for a cooking appliance provided in Embodiment 3 of the present invention. Figure 5 As shown, the device includes:

[0117] The overflow prevention parameter threshold determination module 310, the current motor speed and current temperature change curve acquisition module 320, the current overflow status determination module 330, and the overflow processing module 340 are included.

[0118] The overflow prevention parameter threshold determination module 310 is used to determine the target overflow prevention parameter threshold based on the current cooking mode and the current cooking scenario.

[0119] The current motor speed and current temperature change curve acquisition module 320 is used to acquire the current motor speed and current temperature change curve of the cooking equipment when the cooking equipment is in the start-up state.

[0120] The current overflow state determination module 330 is used to collect the actual value of the overflow prevention parameter if the current motor speed and the current temperature change curve meet the overflow prevention trigger condition, and determine the current overflow state based on the target overflow prevention parameter threshold and the actual value of the overflow prevention parameter; wherein, the current overflow state includes overflow and non-overflow.

[0121] The overflow handling module 340 is used to put the cooking device into a stop state if the current overflow state is overflow, and restart the cooking device when the current overflow state is not overflow.
