Description

Technical Field

[0001] This application relates to the field of rice cooker and intelligent cooking control technology, and more specifically, to a method for pre-cooking rice cookers, electronic devices, and rice cookers. Background Technology

[0002] Rice cookers, a common kitchen appliance in modern households, are primarily used for cooking rice, steaming, and other similar functions. However, traditional rice cookers have significant shortcomings in scenarios involving long-term preset cooking, especially when users need to cook frozen foods overnight. Because traditional rice cookers typically lack a preservation function, food remains at room temperature for extended periods during the preset cooking process, making it prone to thawing and deformation. Furthermore, it is highly susceptible to spoilage at higher temperatures, impacting the user experience and potentially posing health risks.

[0003] Therefore, how to effectively maintain the freshness of ingredients during the reservation cooking process has become a technical problem that urgently needs to be solved. Summary of the Invention

[0016] If the difference is less than the preset time threshold, or if the weather temperature during the scheduled time period is determined to be greater than the preset temperature threshold based on the weather temperature data, then the required number of ice cubes for the rice cooker will be determined based on the cooking time, the scheduled time, and the weather temperature data, and the user will be prompted to put the required number of ice cubes into the inner pot of the rice cooker.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0045] It should be understood that "multiple" as mentioned herein refers to two or more. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. In addition, to facilitate a clear description of the technical solutions of the embodiments of this application, the terms "first," "second," etc., are used in the embodiments of this application to distinguish identical or similar items with substantially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and the terms "first," "second," etc., do not necessarily imply that they are different.

[0046] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0047] First, the terminology used in the embodiments of this application will be introduced.

[0048] Wi-Fi, or wireless network communication technology, is used to connect network-connectable devices to each other wirelessly.

[0049] As mentioned in the background technology, rice cookers, as a common kitchen appliance in modern households, are mainly used for cooking rice, steaming, and other cooking functions. However, traditional rice cookers have significant shortcomings in scenarios involving long-term preset cooking, especially when users need to cook frozen foods overnight. Since traditional rice cookers typically lack a preservation function, food remains at room temperature for extended periods during the preset cooking process, making it prone to thawing and deformation, and easily spoiling at higher temperatures. This not only affects the user experience but may also pose potential health threats. While some high-end rice cookers do have some heat preservation or cooling functions, their design primarily focuses on keeping food warm after cooking, rather than preserving freshness during the preset cooking process. Furthermore, in practical applications, these devices are often limited by ambient temperature and the device's heat dissipation performance, making it difficult to maintain a low temperature for extended periods, resulting in poor preservation. Therefore, how to effectively maintain the freshness of food during preset cooking has become a pressing technical challenge.

[0050] This invention aims to propose an innovative solution by combining factors such as reservation time, cooking time, and ambient temperature. During the reservation stage, a low-temperature environment is maintained through the synergistic effect of cooling plates and ice cubes, thereby significantly improving the preservation effect of food and providing users with a healthier and more convenient cooking experience.

[0051] Based on this, the embodiments of this application provide a method for pre-cooking rice cookers, referring to... Figure 1 The diagram shows the process flow of the rice cooker's timer cooking method, which includes the following steps.

[0052] S101: Obtain the cooking time and preset time of the rice cooker, and obtain the weather temperature data during the preset time period.

[0053] In specific implementation, the cooking time and preset time of the rice cooker are obtained. The cooking time can be determined based on the user's operation instructions to the rice cooker, and the preset time can be determined based on the cooking time set by the user, or directly based on the preset time entered by the user. Weather temperature data can be obtained through specific data input methods, such as obtaining the weather forecast for the user's location from the user's smart device, or through Wi-Fi or wired connection. This embodiment of the invention does not limit the specific methods used.

[0054] S102: Determine the amount of ice needed for the rice cooker based on cooking time, preset time, and weather temperature data.

[0055] In practice, the amount of ice needed to help control the temperature is predicted based on the cooking time, the reservation time, and the weather temperature data. That is, the amount of ice needed for the rice cooker is added, and no less than the required amount of ice is added. This can be done by instructing the user to add ice, or by adding ice from a device that stores ice, such as a smart refrigerator, through other automatic devices. This embodiment of the invention does not limit this.

[0056] S103: When the remaining time of the reservation is greater than the cooking time, ice cubes and a cooling module are used to maintain the temperature of the inner pot cavity of the rice cooker within the preset range.

[0057] In practice, ice and a cooling module work together to keep the temperature of the inner pot cavity of the rice cooker within a preset range, and the remaining time is determined based on the preset time and cooking time.

[0058] S104: Start cooking when the remaining time of the reservation is less than or equal to the cooking time.

[0059] In practice, when the remaining time is less than or equal to the cooking time, the ice is heated until it melts, and the water from the melted ice is used for cooking.

[0060] This embodiment allows for flexible addition of ice to the rice cooker for cooling, preservation, and cooking based on cooking time, preset time, and weather temperature data. The cooling module maintains the inner pot cavity temperature within a preset range while slowing down the melting of the ice. This solves the problem of food spoilage when cooking overnight in traditional rice cookers, achieving a balance between preservation and energy saving, and enhancing the user experience.

[0061] In the above embodiments of this application, the descriptions of each embodiment have their own emphasis. Parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments. The steps illustrated in the related flowcharts can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown here. In other words, the order of steps described in the foregoing embodiments is merely an example. Reasonable adjustments to the order of steps based on the content of the embodiments of this application are also within the protection scope of the embodiments of this application.

[0062] In one specific implementation of this application embodiment, the rice cooker's preset cooking method is as follows: Figure 2 The following processing steps are shown:

[0063] S201: In response to the user's preset cooking settings for the rice cooker, obtain the cooking time and preset time entered by the user.

[0064] In practice, the cooking time required for the selected cooking type can be determined by the user's operation of the rice cooker and the ingredients added to it. The cooking time can also be determined based on the user's set cooking time or the preset time entered by the user.

[0065] In one example, when a user selects the steaming function, the corresponding cooking time t1 and the reservation time t2 are determined. The reservation time refers to the total time from the start of the reservation to the end of the steaming function.

[0066] S202: Obtain weather temperature data for the scheduled time period through a network interface and / or wireless network communication technology.

[0067] In practice, weather temperature data can be obtained through data input methods, such as obtaining weather forecasts for the user's area through the user's smart device, or through Wi-Fi or wired connections.

[0068] Using the same example as above, the rice cooker obtains the future weather temperature T1 within the scheduled time range via WIFI.

[0069] S203: Determine the amount of ice needed for the rice cooker based on cooking time, preset time, and weather temperature data.

[0070] In practice, the amount of ice needed to help control the temperature is predicted based on the cooking time, the reservation time, and the weather temperature data. That is, the amount of ice needed for the rice cooker is added, and no less than the required amount of ice is added. This can be done by instructing the user to add ice, or by adding ice from a device that stores ice, such as a smart refrigerator, through other automatic devices. This embodiment of the invention does not limit this.

[0071] In one possible implementation, if the difference between the reservation time and the cooking time is greater than or equal to a preset time threshold, and the weather temperature during the reservation period is determined to be less than or equal to a preset temperature threshold based on weather temperature data, it indicates that cooking will take place in a short time, and there is no need for prolonged refrigeration to ensure food freshness. In this case, the user is prompted to add only an appropriate amount of water, without adding ice. The preset time threshold can be set according to needs, for example, adjusted based on the type of ingredients, regional temperature, humidity, etc. This embodiment of the invention does not limit this; the following explanation uses a preset time threshold of 1 hour as an example.

[0072] In this embodiment, the inner pot cavity temperature can also be obtained in real time. If the difference is greater than or equal to a preset time threshold, and the weather temperature during the reserved time period is less than or equal to a preset temperature threshold, and the inner pot cavity temperature is also less than a preset temperature threshold, the user will be reminded not to add ice.

[0073] Using the above example, if the difference t3 between the reservation time and the cooking time is greater than or equal to 1 hour, and the future weather temperature within the reservation time range is less than or equal to 4°C and the temperature sensed on the top of the rice cooker is less than or equal to 4°C, then the user will be prompted via voice, mobile phone or rice cooker display to "Please add water to the inner pot, and the amount of water added should not be lower than the steaming water level line".

[0074] Correspondingly, if the difference is less than a preset time threshold, or if the weather temperature during the scheduled time period is determined to be greater than the preset temperature threshold based on weather temperature data, the required number of ice cubes for the rice cooker is determined based on the cooking time, scheduled time, and weather temperature data, and the user is prompted to add the required number of ice cubes to the inner pot of the rice cooker. The specific number of ice cubes to add is first determined by the initial number of ice cubes in the rice cooker based on the cooking time, scheduled time, and weather temperature data. This initial number can also be adjusted based on the real-time ambient temperature of the rice cooker to arrive at the final ice cube count.

[0075] In one possible implementation, the number of ice cubes n is determined based on the user-set cooking time t1, the preset time t2, the weather temperature T1 obtained from the internet during the preset time period, and the temperature sensed at the top of the rice cooker (i.e., the real-time ambient temperature of the rice cooker) T2. The longer the cooking time, the longer the preset time, and the higher the weather temperature, the more ice cubes are required. The specific calculation formula is as follows:

[0076]

[0077] Where the number of ice cubes is n, t1 is the cooking time, t2 is the reservation time, the weather temperature data is T1, and t3 is the difference between the reservation time and the cooking time, i.e., t3 = t2 - t1. It should be noted that the formula values ​​in this embodiment are obtained by nonlinear surface fitting based on experimental data, and can be modified according to needs. This embodiment does not limit this.

[0078] Additionally, the required number of ice cubes can be adjusted based on the temperature T2 sensed at the top of the rice cooker. Specifically, based on the above, the temperature T2 sensed at the top of the rice cooker is further determined. If T2 ≤ T1, it is determined that the environment where the rice cooker is located is the same as the outdoor temperature, and the number of ice cubes added remains unchanged. If T2 > T1, it is determined that the environment where the rice cooker is located is higher than the outdoor temperature, and the number of ice cubes added is adjusted to n+x.

[0079] x = 0.5 * (T2 - T1);

[0080] Where x is the amount of ice added, which is a positive integer.

[0081] In another possible implementation, the amount of ice to be added in different situations is determined by using a pre-calculated correspondence table.

[0082] In one example, if 5min≤t1≤15min, 1H<t2-t1≤6H, and 4℃<T1≤15℃, then it is determined that the environment where the rice cooker is located is the same as the outdoor temperature, and n1 ice cubes are added.

[0083] If 5min≤t1≤15min, 1H≤t2-t1≤6H, and 15℃<T1≤25℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n2 ice cubes should be added.

[0084] If 5min≤t1≤15min, 1H≤t2-t1≤6H, and 25℃<T1≤35℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n3 ice cubes should be added.

[0085] If 5min≤t1≤15min, 1H≤t2-t1≤6H, and T1>35℃, then the environment of the rice cooker is higher than the room temperature, and n4 ice cubes should be added.

[0086] If 5min≤t1≤15min, 6H<t2-t1≤12H, and 4℃<T1≤15℃, then it is determined that the environment where the rice cooker is located is the same as the outdoor temperature, and n5 ice cubes are added.

[0087] If 5min≤t1≤15min, 6H<t2-t1≤12H, and 15℃<T1≤25℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n6 ice cubes should be added.

[0088] If 5min≤t1≤15min, 6H<t2≤12H, and 25℃<T1≤35℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n7 ice cubes should be added.

[0089] If 5min≤t1≤15min, 6H<t2-t1≤12H, and T1>35℃, then the environment of the rice cooker is higher than the room temperature, and n8 ice cubes should be added.

[0090] If 15min<t1≤30min, 1H<t2-t1≤6H, and 4℃<T1≤15℃, then it is determined that the environment where the rice cooker is located is the same as the outdoor temperature, and n9 ice cubes are added.

[0091] If 15min<t1≤30min, 1H≤t2-t1≤6H, and 15℃<T1≤25℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n10 ice cubes should be added.

[0092] If 15min<t1≤30min, 1H≤t2-t1≤6H, and 25℃<T1≤35℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n11 ice cubes should be added.

[0093] If 15min<t1≤30min, 1H≤t2-t1≤6H, and T1>35℃, then the environment of the rice cooker is higher than the room temperature, and n12 ice cubes should be added.

[0094] If 15min<t1≤30min, 6H<t2-t1≤12H, and 4℃<T1≤15℃, then it is determined that the environment where the rice cooker is located is the same as the outdoor temperature, and n13 ice cubes are added.

[0095] If 15min<t1≤30min, 6H<t2-t1≤12H, and 15℃<T1≤25℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n14 ice cubes should be added.

[0096] If 15min<t1≤30min, 6H<t2-t1≤12H, and 25℃<T1≤35℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n15 ice cubes should be added.

[0097] If 15min<t1≤30min, 6H<t2-t1≤12H, and T1>35℃, then it is determined that the environment of the rice cooker is higher than the room temperature, and n16 ice cubes should be added.

[0098] Among them, 20 blocks ≤ n1 < n2 < n3 < n4 < n5 < n6 < n7 < n8 < n9 < n10 < n11 < n12 < n13 < n14 < n15 < n16 ≤ 50 blocks.

[0099] S204: When the remaining time of the reservation is greater than the cooking time, ice cubes and a cooling module are used to maintain the temperature of the inner pot cavity of the rice cooker within the preset range.

[0100] In practice, ice cubes and a refrigeration module work together to lower the temperature, ensuring that the temperature of the inner pot cavity of the rice cooker remains within a preset range. This preset range can be set according to requirements, and this embodiment of the invention does not limit it. In one example, the preset range can be from 0°C to 4°C.

[0101] In practice, the temperature of the inner pot cavity is first acquired in real time. Then, when the temperature of the inner pot cavity is higher than the first temperature threshold, the cooling module is activated to lower the temperature. When the temperature of the inner pot cavity is lower than the second temperature threshold, the cooling module is stopped. The first temperature threshold should not be less than the highest value of the preset range, and the second temperature threshold should not be less than the lowest value of the preset range. The specific values ​​can be set according to requirements.

[0102] In one possible implementation, the preset range can be adjusted as cooking approaches. Specifically, if the difference between the reservation time and the cooking time is greater than or equal to a preset time threshold, and the weather temperature during the reservation period is determined to be less than or equal to a preset temperature threshold based on weather temperature data, then when the inner pot cavity temperature is higher than a third temperature threshold, the cooling module is activated to cool down the pot. When the inner pot cavity temperature is lower than a first temperature threshold, the cooling module is stopped. Here, the third temperature is higher than the first temperature threshold.

[0103] Using the example above, if the difference t3 between the preset time and the cooking time is less than 1 hour, and the future weather temperature within the preset time range is less than or equal to 4℃ and the temperature sensed at the top of the rice cooker is less than or equal to 4℃, the preset range is 4℃-21℃; otherwise, the preset range is 0℃-4℃. When the remaining preset time is less than or equal to the sum of the preset maximum heating time (approximately 10 minutes) and the cooking timer, the cooking stage begins.

[0104] S205: Start cooking when the remaining time of the reservation is less than or equal to the cooking time.

[0105] In practice, the rice cooker is used in the conventional cooking mode, which involves heating and melting the ice-water mixture in the pot.

[0106] In one specific implementation of the embodiments of this application, the description is based on a rice cooker's timed cooking method and a rice cooker.

[0107] A rice cooker may include a cooling module, a heat preservation module, a temperature detection module, a control module, an inner pot, temperature sensing elements, and a heating module. The cooling module is installed inside the rice cooker lid and closely adheres to the top area of ​​the inner pot. It is tightly bonded to the metal base plate on the top of the inner pot via thermal grease, and the heat sink in the cooling module is connected to the outer shell of the rice cooker for heat dissipation. The heat preservation module is located between the outer wall and bottom of the inner pot, employing a double-layer vacuum structure with a layer thickness of 2 mm to 5 mm, typically made of stainless steel, to insulate against external heat transfer. The temperature detection module includes top and bottom temperature sensing elements, installed at the top and bottom of the inner pot cavity respectively, for real-time monitoring of temperature changes. The control module connects the cooling module, temperature detection module, and heating module via circuitry, dynamically adjusting the operating status of each module based on user-input preset parameters.

[0108] In practical applications, after the user inputs the cooking time and reservation time through the control module, the module obtains the weather temperature data for the reserved time period via a network interface or Wi-Fi, and calculates the required amount of ice based on this data. Specifically, if the difference between the reservation time and the cooking time is greater than or equal to 1 hour, and the weather temperature during the reserved time period is less than or equal to 4℃, the control module prompts the user to add only an appropriate amount of water; otherwise, it prompts the user to add the calculated amount of ice to the inner pot. During this process, the top temperature sensor monitors the temperature of the inner pot cavity in real time and transmits the data to the control module, which can then adjust the base ice quantity based on the real-time ambient temperature.

[0109] During the pre-set phase, the control module maintains the inner pot cavity temperature within a preset range via the cooling module. When the top temperature sensor detects that the inner pot cavity temperature exceeds the preset upper limit, the control module activates the cooling module to lower the temperature; when the top temperature sensor detects that the inner pot cavity temperature falls below the preset lower limit, the control module stops the cooling module. The preset temperature range is dynamically adjusted based on the difference between the pre-set time and the cooking time, as well as the weather temperature. If the difference between the pre-set time and the cooking time is less than 1 hour and the weather temperature is less than or equal to 4°C, the preset temperature range is 4°C to 21°C; otherwise, the preset temperature range is 0°C to 4°C. During this process, the semiconductor cooling chip in the cooling module rapidly conducts heat to the heat sink via thermal grease, and the heat sink dissipates the heat to the external environment through the rice cooker's outer shell, thereby reducing the inner pot cavity temperature.

[0110] During the cooking phase, when the remaining time is less than or equal to the sum of the preset heating time and cooking time, the control module activates the heating module to enter cooking mode. The heating module is located at the bottom of the inner pot. A bottom temperature sensor monitors the bottom temperature of the inner pot in real time and transmits the data to the control module. The control module dynamically adjusts the power output of the heating module based on the temperature data, ensuring that the ice-water mixture in the inner pot is gradually heated to boiling. During this process, the double-layer vacuum structure of the insulation module effectively reduces heat transfer from the outside, preventing heat loss during heating. Simultaneously, a top temperature sensor continuously monitors the temperature of the inner pot cavity and feeds the data back to the control module, ensuring a stable cooking process.

[0111] In one possible implementation, the control module further includes a temperature judgment module, used to determine whether the temperature of the inner pot cavity exceeds a preset range based on the detection result of the top temperature sensing element. When the temperature exceeds the preset range, the temperature judgment module sends a start or stop command to the refrigeration module to ensure that the temperature of the inner pot cavity remains within the preset range. In addition, the control module includes a correction module, used to correct the basic ice quantity based on the real-time ambient temperature detected by the top temperature sensing element. When the real-time ambient temperature is higher than the weather temperature, the correction module increases the ice quantity; when the real-time ambient temperature is lower than or equal to the weather temperature, the correction module keeps the basic ice quantity unchanged.

[0112] In practice, after placing the prepared ingredients into the inner pot, the user needs to set the cooking time and preset time via the control module. The control module obtains the weather temperature data for the preset time period through a network interface and calculates the required amount of ice based on the difference between the preset time and the cooking time, as well as the weather temperature. If the difference between the preset time and the cooking time is greater than or equal to 1 hour and the weather temperature is less than or equal to 4℃, the user is prompted to add only an appropriate amount of water; otherwise, the required amount of ice is calculated. During this process, the temperature sensing element at the top continuously monitors the temperature of the inner pot cavity and transmits the data to the control module, thereby ensuring the accuracy of the ice quantity.

[0113] During the pre-set period, the cooling and heat preservation modules work together to maintain the inner pot cavity temperature within a preset range. When the top temperature sensor detects that the inner pot cavity temperature exceeds the preset upper limit, the control module activates the cooling module. The semiconductor cooling chip uses thermal grease to quickly conduct heat from the top area of ​​the inner pot to the heat sink, which then dissipates the heat through the rice cooker's outer shell to the external environment, thereby lowering the inner pot cavity temperature. When the top temperature sensor detects that the inner pot cavity temperature falls below the preset lower limit, the control module stops the cooling module. The preset temperature range is dynamically adjusted based on the difference between the pre-set time and the cooking time, as well as the weather temperature: if the difference is less than 1 hour and the weather temperature is less than or equal to 4°C, the preset temperature range is 4°C to 21°C; otherwise, it is 0°C to 4°C. During this process, the double-layer vacuum structure of the heat preservation module effectively isolates external heat transfer, slowing down the melting of ice and ensuring the food remains fresh in a low-temperature environment.

[0114] When the remaining time is less than or equal to the sum of the preset heating and cooking times, the control module activates the heating module to enter cooking mode. The heating module, located at the bottom of the inner pot, monitors the bottom temperature in real time via a bottom temperature sensor and transmits the data to the control module. The control module dynamically adjusts the power output of the heating module based on the temperature data, gradually heating the ice-water mixture in the inner pot to boiling. During this process, the double-layer vacuum structure of the insulation module continues to reduce heat transfer from the outside, preventing heat loss during heating. Simultaneously, the top temperature sensor continuously monitors the temperature of the inner pot cavity and feeds the data back to the control module, ensuring stable cooking.

[0115] Furthermore, throughout the entire pre-cooking process, the temperature judgment module in the control module determines whether the temperature of the inner pot cavity exceeds the preset range based on the detection results of the temperature sensing element at the top. When the temperature exceeds the preset range, the temperature judgment module sends a start or stop command to the cooling module to ensure that the temperature of the inner pot cavity remains within the preset range. Simultaneously, the correction module dynamically adjusts the base ice quantity based on the real-time ambient temperature detected by the top temperature sensing element. When the real-time ambient temperature is higher than the weather temperature, the number of ice cubes is increased; conversely, the base ice quantity remains unchanged. This mechanism ensures a balance between preservation effect and energy consumption.

[0116] Through the above steps, the smart rice cooker can dynamically adjust the working status of each module based on the user-input preset parameters and the external ambient temperature. This maintains a low-temperature environment inside the inner pot during the preset cooking stage, slowing down the melting of ice and ensuring the food remains fresh. During the cooking stage, the heating module heats the ice-water mixture to boiling, completing the cooking process. Throughout the entire process, the temperature detection module monitors the temperature of the inner pot cavity and bottom in real time, and the control module dynamically adjusts the working status of each module based on the temperature data, ensuring a stable and efficient preset cooking process. This technical solution solves the problem of food spoilage when cooked overnight in traditional rice cookers, while achieving a balance between preservation and energy saving, thus improving the user experience.
