Description

Technical Field

[0001] This invention relates to the technical field of refrigerator refrigeration, and more particularly to a method for quick-freezing and preserving food in a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it's also a consumer product that keeps food or other items at a constant low temperature. Modern refrigerators have a wide temperature adjustment range, requiring users to set the temperature according to the types of food they are storing. However, most users don't know the corresponding storage temperatures for different foods and cannot accurately set the refrigerator temperature. In other words, the temperature of existing refrigerators requires manual adjustment; people usually set the temperature based on experience. Since the types of items in the refrigerator, such as carbonated drinks, fruit juices, and herbal teas, differ in their storage conditions, manual adjustment cannot guarantee that all items are stored at the appropriate temperature, thus reducing the refrigerator's intelligence.

[0003] For example, existing technology CN206583182U discloses a refrigerator with scene-based control logic. The disclosed solution uses a temperature setting device; users only need to select the type of food on the refrigerator's operating interface or a mobile app, and the refrigerator will automatically enter the appropriate storage temperature for the food, eliminating the need for users to manually set the temperature range and the hassle of temperature settings. In the aforementioned refrigerator with scene-based control logic, the temperature setting device includes a mobile phone or a touchscreen, both of which have an operating interface with scene-based function keys corresponding to various food types. Users can conveniently control the refrigerator's temperature remotely via a mobile app or directly via the touchscreen, making operation quite simple.

[0004] However, this interaction method can only set a single temperature for all types of food, and it achieves temperature management for the same scenario through a scenario-based approach. This control logic cannot achieve more precise temperature settings.

[0005] Furthermore, different foods have different cooling requirements for refrigerators. Some foods need to be cooled quickly to keep them fresh, while others do not need to be frozen quickly. Refrigerators need to implement more precise and granular cooling control for different foods.

[0006] At the same time, existing refrigerators do not take into account the temperature regulation needs of the food or stored items inside the refrigerator. They simply set a fixed temperature regulation strategy without being able to change it dynamically. This not only wastes energy and is not environmentally friendly, but also fails to control the temperature of the food that users care about more. Summary of the Invention

[0007] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention discloses a method for quick-freezing and preserving food in a refrigerator. The refrigerator is a smart quick-freezing and preserving refrigerator, which has a basic cooling function and a smart cooling function. The basic cooling function directly cools the interior space of the refrigerator according to a preset fixed power, and stops cooling after the interior temperature reaches a first preset value. The smart cooling function is an additional cooling adjustment mode. The method includes the following steps:

[0008] Step 1: Initialize the quick-freezing and preservation smart refrigerator. The initialization involves activating the refrigerator's basic cooling function and obtaining the communication address of the control terminal. The quick-freezing and preservation smart refrigerator actively communicates with the user's control terminal to obtain the preservation preferences input by the user through the control terminal.

[0009] Step 2: The quick-freezing and preservation smart refrigerator modifies the basic cooling function to the smart cooling function, and formulates a freezing and preservation strategy based on the user's input preservation preference. The freezing and preservation strategy is to calculate the first change curve of cooling power and temperature corresponding to the current user's preservation preference using the smart cooling function of the quick-freezing and preservation smart refrigerator. The refrigerator first executes the cooling control strategy corresponding to the first change curve.

[0010] Step 3: Within a preset time period, when the camera device captures the food items stored or retrieved by the user, the smart refrigerator generates a second change curve by changing the cooling power and temperature control strategy according to the changes in the food items inside the refrigerator. The refrigerator then modifies the corresponding cooling control strategy according to the second change curve. The changes in the food items further include: calculating the weight data of each food item inside the refrigerator based on the user's input preservation preferences. Temperature control adjustment is only performed when the weight data corresponding to the food items stored or retrieved by the user, captured by the camera device, reaches a second preset value.

[0011] Step 4: After modifying the refrigeration control strategy, when the slope of the second change curve is greater than the third preset value, temperature monitoring is performed at the temperature point corresponding to the second change to detect whether the change in the quick-freezing strategy has an impact on the preferred ingredients beyond expectations. If it exceeds expectations, feedback is sent to the control terminal.

[0012] Furthermore, the control terminal communicates with the quick-freezing and preservation smart refrigerator via a wireless local area network and / or a cellular network.

[0013] Furthermore, the preservation preference is a user-inputted preference for a non-set refrigeration temperature, and the user-inputted preference is expressed in a specific table format, which shows the preferred ingredients and the preservation level of the preferred ingredients.

[0014] Furthermore, the user's input preferences are the preference for ingredients to be kept fresh first and the expected preservation results. The smart refrigerator quantifies the user's input preferences and assigns weights to all objects that may be stored in the refrigerator according to the user's preferred ingredients. Each ingredient has a corresponding temperature control strategy in the database stored in the smart refrigerator or in the cloud processing server. The temperature control strategy for each ingredient is different according to the different preservation levels.

[0015] Furthermore, the camera device captures the user's storage or retrieval actions. Its switch is triggered by turning on the interior light of the refrigerator when the user opens or closes it, simultaneously waking up the camera device. After being woken up, the camera device directly performs the photo-taking function, and the photo-taking area is a pre-set area, which includes the food that the user takes out and / or puts in.

[0016] Furthermore, while the camera device is capturing images of the user, the temperature of the object placed by the user is detected by a temperature sensing device. If the temperature exceeds a threshold, the cooling strategy needs to be readjusted.

[0017] Furthermore, when the preservation level is level 3, the temperature control strategy for each type of food corresponds to 3 temperature and time change curves. After the user inputs their preferences, the preference weight and preservation level for each type of food are determined immediately, and a temperature and time change curve for each type of food is determined based on the preference weight and preservation level.

[0018] Furthermore, the freezing and preservation strategy, which calculates the user's current preservation preferences using the refrigerator's intelligent cooling function, further includes the first change curve of cooling power versus temperature, which the refrigerator needs to reach at any given time, as well as the temperature value T. total The formula is:

[0019] T total =K1*T Ingredients1 +K2*T Ingredients2 +....+KN*T ngredientsN / (K1+K2+K3+...+KN)

[0020] Among them, T Ingredients1 ....T IngredientsN This represents the temperature set for N ingredients at the current moment based on the user's selected preferences, where K1...KN represent the weight values ​​of the N ingredients.

[0021] Furthermore, the first curve showing the change in cooling power versus temperature is further represented as follows:

[0022] P=αΔT total +β

[0023] Where P is the cooling power, ΔT total T represents total The rate of change, α represents the amplification factor, and β represents the bias factor. α and β are factory settings for the refrigerator and cannot be modified by the user through the control terminal.

[0024] Furthermore, the first preset value, the second preset value, and the third preset value are parameter values ​​that the user can modify through the control terminal.

[0025] Compared with the prior art, the beneficial effects of the present invention are very significant. The beneficial effects of the present invention are as follows: the present invention does not require the user to input the set temperature, but only requires the user to input their own set preferences, such as the type of food they prefer, and automatically adjusts the temperature. At the same time, the present invention also adjusts the temperature by adding or removing food. In order to prevent frequent adjustments, a significant advantage of the present invention is that different food is assigned weights, and the temperature control strategy is only adjusted when the weight is greater than a preset value. Furthermore, the temperature adjustment strategy is evaluated to ensure the effectiveness of the temperature adjustment strategy. Attached Figure Description

[0028] Figure 2 This is a flowchart of temperature control strategy adjustment in one embodiment of the present invention. Detailed Implementation

[0029] Example 1

[0030] like Figure 1 As shown, this embodiment provides a method for quick-freezing and preserving food in a refrigerator. The refrigerator is a smart quick-freezing and preservation refrigerator, which has a basic cooling function and a smart cooling function. The basic cooling function directly cools the interior space of the refrigerator according to a preset fixed power, and stops cooling after the interior temperature reaches a first preset value. The smart cooling function is an additional cooling adjustment method. The method includes the following steps:

[0031] Step 1: Initialize the quick-freezing and preservation smart refrigerator. The initialization involves activating the refrigerator's basic cooling function and obtaining the communication address of the control terminal. The quick-freezing and preservation smart refrigerator actively communicates with the user's control terminal to obtain the preservation preferences input by the user through the control terminal.

[0032] In this embodiment, the user does not need to input a set temperature, but only their own preferences, such as the type of food they prefer. The interaction method is in the form of a table, where the user enters their preferences in rows and columns. Each row of the table corresponds to a type of food that can be selected from a drop-down list, and each column also has a preference that can be selected from a drop-down list. For example, the preferred type of food can be selected as "very much preferred", "preferable", "not preferred", etc. The corresponding insurance level can also be set in the same way, which will not be elaborated further here.

[0033] Step 2: The quick-freezing and preservation smart refrigerator modifies the basic cooling function to the smart cooling function, and formulates a freezing and preservation strategy based on the user's input preservation preference. The freezing and preservation strategy is to calculate the first change curve of cooling power and temperature corresponding to the current user's preservation preference using the smart cooling function of the quick-freezing and preservation smart refrigerator. The refrigerator first executes the cooling control strategy corresponding to the first change curve.

[0034] In this embodiment, the first curve of the change between refrigeration power and temperature corresponding to the preservation preference can be plotted using the device's refrigeration capacity-temperature as a coordinate system or the compressor power-temperature as a coordinate system, because there is a preset equation mapping relationship between refrigeration capacity and compressor power when specific parameters do not change.

[0035] Step 3: Within a preset time period, when the camera device captures the food items stored or retrieved by the user, the smart refrigerator generates a second change curve by changing the cooling power and temperature control strategy according to the changes in the food items inside the refrigerator. The refrigerator then modifies the corresponding cooling control strategy according to the second change curve. The changes in the food items further include: calculating the weight data of each food item inside the refrigerator based on the user's input preservation preferences. Temperature control adjustment is only performed when the weight data corresponding to the food items stored or retrieved by the user, captured by the camera device, reaches a second preset value.

[0036] In this embodiment, the preset time period can be a user-defined time period, such as a week or a specific number of days. After the set time period expires, the smart refrigerator sends a message to the control terminal, requesting the time to be reset and notifying the user to check the food.

[0037] Step 4: After modifying the refrigeration control strategy, when the slope of the second change curve is greater than the third preset value, temperature monitoring is performed at the temperature point corresponding to the second change to detect whether the change in the quick-freezing strategy has an impact on the preferred ingredients beyond expectations. If it exceeds expectations, feedback is sent to the control terminal.

[0038] Furthermore, the control terminal communicates with the quick-freezing and preservation smart refrigerator via a wireless local area network and / or a cellular network.

[0039] Furthermore, the preservation preference is a user-inputted preference for a non-set refrigeration temperature, and the user-inputted preference is expressed in a specific table format, which shows the preferred ingredients and the preservation level of the preferred ingredients.

[0040] Furthermore, the user's input preferences are the preference for ingredients to be kept fresh first and the expected preservation results. The smart refrigerator quantifies the user's input preferences and assigns weights to all objects that may be stored in the refrigerator according to the user's preferred ingredients. Each ingredient has a corresponding temperature control strategy in the database stored in the smart refrigerator or in the cloud processing server. The temperature control strategy for each ingredient is different according to the different preservation levels.

[0041] like Figure 2 As shown, in this embodiment, the camera device captures the user's storage or retrieval actions. The switch is triggered by turning on the interior light of the refrigerator when the user opens or closes it, and simultaneously waking up the camera device. After being woken up, the camera device directly performs the photo-taking function, and the photo-taking area is a pre-set area, which includes the food that the user takes out and / or puts in.

[0042] Furthermore, while the camera device is capturing images of the user, the temperature of the object placed by the user is detected by a temperature sensing device. If the temperature exceeds a threshold, the cooling strategy needs to be readjusted.

[0043] Furthermore, when the preservation level is level 3, the temperature control strategy for each type of food corresponds to 3 temperature and time change curves. After the user inputs their preferences, the preference weight and preservation level for each type of food are determined immediately, and a temperature and time change curve for each type of food is determined based on the preference weight and preservation level.

[0044] Furthermore, the freezing and preservation strategy, which calculates the user's current preservation preferences using the refrigerator's intelligent cooling function, further includes the first change curve of cooling power versus temperature, which the refrigerator needs to reach at any given time, as well as the temperature value T. total The formula is:

[0045] T total =K1*T Ingredients1 +K2*T Ingredients2 +....+KN*T ngredientsN / (K1+K2+K3+...+KN)

[0046] Among them, T Ingredients1 ....T IngredientsNThis represents the temperature set for N ingredients at the current moment based on the user's selected preferences, where K1...KN represent the weight values ​​of the N ingredients.

[0047] In this embodiment, the set temperature is a mapping between the preferences for different ingredients and the corresponding temperature settings stored in the database.

[0048] Furthermore, the first curve showing the change in cooling power versus temperature is further represented as follows:

[0049] P=αΔT total +β

[0050] Where P is the cooling power, ΔT total T represents total The rate of change, α represents the amplification factor, and β represents the bias factor. α and β are factory settings for the refrigerator and cannot be modified by the user through the control terminal.

[0051] Furthermore, the first preset value, the second preset value, and the third preset value are parameter values ​​that the user can modify through the control terminal.

[0052] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
