Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a method, system, and storage medium for controlling the operating mode of a refrigerator. Background Technology

[0002] In daily life, refrigerators have become an indispensable household appliance. Currently, although different compartments of a refrigerator support different modes and settings, such as a quick-cooling mode for the refrigerator compartment, a quick-freezing mode for the freezer compartment, and a baby-safe mode for the variable temperature compartment, refrigerators are still widely used.

[0003] However, refrigerator mode settings are highly subjective and, once set, operate at a fixed temperature and time. In other words, refrigerator mode settings cannot be adapted to people's actual habits or the food stored in the refrigerator. For example, people may not use the refrigerator for a long time, but the mode is not set to holiday mode; or the refrigerator may be full of food, but the mode is not set to quick cooling or quick freezing mode. This not only fails to achieve optimal cooling performance but also does not reduce the refrigerator's power consumption. Summary of the Invention

[0009] As a further improvement of the present invention, the method further includes: if the food storage state is a normal state, then adjusting the refrigerator operating mode according to the current mode; if the refrigerator is not currently set to a mode, then maintaining the refrigerator in its current state until... After a certain time, set to holiday mode; if the current refrigerator is set to non-holiday mode, then keep the current refrigerator in its current mode until T. l After a certain time, set it to holiday mode; if the current refrigerator is set to holiday mode, then the current refrigerator will remain in holiday mode.

[0010] As a further improvement of the present invention, the method further includes: if the food storage volume is saturated, adjusting the refrigerator operating mode according to the current mode; if the refrigerator is not currently set to a mode or is not set to a quick-cooling mode or quick-freezing mode, setting the refrigerator to a quick-cooling mode or quick-freezing mode and operating it. After a certain time, set to holiday mode; if the refrigerator is currently set to quick cooling or quick freezing mode, then determine the remaining running time T. l Is it greater than If so, the refrigerator will remain in this mode until T. l After a certain time, set it to holiday mode; otherwise, keep the refrigerator in that mode until...

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] This application discloses a refrigerator operation mode control method according to one embodiment, although this application provides the following embodiments or processes. Figure 1 and Figure 2The method described herein involves steps that, while based on conventional or non-creative labor, involve steps where there is no logically necessary causal relationship, the execution order of these steps is not limited to the order provided in the embodiments of this application. For example... Figure 1 As shown in the figure, this invention provides a refrigerator operation mode control method, which includes the following steps, and the method and each step are described below:

[0025] S1 acquires the parameter data of the refrigerator during operation and uploads it to the cloud server to obtain the average door opening time interval and the current door opening time interval;

[0026] In daily life, when a refrigerator is powered on and starts running, its main control board can record parameter data during operation. For example, the main control board can record the number of times the refrigerator door is opened per unit time and the total opening time, collected continuously by the door opening sensor, and upload this information to a cloud server. The cloud server then calculates the average door opening interval and the current door opening interval based on the received parameter information.

[0027] Specifically, assuming the number of times the refrigerator door is opened within the current d days is n, and the times of two consecutive openings are t1 and t2, then the time interval between the first openings is Δt1 = t2 - t1. The current time interval is the difference between the current opening time and the last opening time, denoted as Δt. now The average door opening time interval is the ratio of the sum of the time intervals Δt between all adjacent door openings within a range of n door openings to the total number of openings (n-1). This average time interval is denoted as Δt. The average door opening time interval can be calculated using formula (1).

[0028]

[0029] S2 constructs a seasonal pairwise comparison matrix to obtain the seasonal weight vector;

[0030] As we all know, temperatures vary in different seasons, which directly affects how often the refrigerator door is opened. In winter, the temperature is low, and food left in the kitchen or on the windowsill for a while won't spoil immediately. Therefore, people may leave food in the kitchen or on the windowsill in winter instead of refrigerating or freezing it, which reduces the number of times the refrigerator door is opened and increases the time interval between openings. In summer, since temperatures in most parts of China generally exceed 25°C, food will spoil much faster if it is not refrigerated. In addition, people like to drink chilled beverages and ice cream in summer, which also greatly increases the frequency of refrigerator use, thus significantly reducing the time interval between openings.

[0031] We can construct a seasonal pairwise comparison matrix Z by taking the reduction of the door opening interval or the increase of the number of times the refrigerator door is opened as the goal. Specifically, we assume that the seasonal pairwise comparison matrix Z can be constructed by formula (2).

[0032]

[0033] Among them, z ij This represents the importance of the i-th factor relative to the j-th factor. A larger value indicates that one factor is more important than another, and vice versa; 1 ≤ i, j ≤ 4 represent the four seasonal factors: spring, summer, autumn, and winter, respectively. For example, z 24 This indicates the relative importance of summer compared to winter in achieving the goal of reducing door opening intervals. Furthermore, z 42 For z 24 The reciprocal of.

[0034] After constructing the pairwise comparison matrix, the largest eigenvalue λ of the matrix can be obtained. max And the corresponding feature vector W, which can be expressed by formula (3).

[0035] W = [w1, w2, w3, w4] (3)

[0036] The feature vector W is normalized to obtain the normalized feature vector W. n o rm The normalized feature vector can be expressed by formula (4).

[0037] W norm =[w norm,1 ,w norm,2 ,w norm,3 ,w norm,4 (4)

[0038] in,

[0039]

[0040] We define the normalized eigenvector W norm Let Φ be the seasonal weight vector, which can be represented by formula (6).

[0041] Φ=[φ1,φ2,φ3,φ4]=[w norm,1 ,w norm,2 ,w norm,3 ,w norm,4 (6)

[0042] in, The seasonal weights are spring, summer, autumn, and winter, respectively.

[0043] S3 obtains the current volume of food in the refrigerator, the refrigerator's rated capacity, and the food storage status, and uploads it to the cloud server;

[0044] The current rated volume V of the refrigerator fridge It is easily obtained, and the infrared sensor installed in the refrigerator compartment can detect the shape and size of the food currently stored in the refrigerator, and thus determine the volume V of the food in the refrigerator compartment. food Based on the refrigerator's rated capacity and the volume of food stored, we can determine the current food storage status within the refrigerator. Specifically, let's assume we define V... food <1 / 3V fridge If the current amount of food in the refrigerator is small, then the amount of food in the refrigerator is small; if 1 / 3V fridge ≤V food <7 / 10V fridge If V, then the food currently placed in the refrigerator is in a normal state; if V food ≥7 / 10V fridge If the refrigerator is saturated with food, then the refrigerator is currently at full capacity. The acquired information is uploaded to a cloud server for storage, providing a basis for subsequent refrigerator mode settings.

[0045] S4 obtains the total running time, elapsed running time, and remaining running time of the current refrigerator mode, as well as the refrigerator mode definition, and uploads them to the cloud server;

[0046] The timer on the refrigerator's main control board can be used to record the total running time T of the current refrigerator mode. r Runtime T d and remaining running time T l The recorded information is uploaded to the cloud server to provide a basis for subsequent dynamic settings of the refrigerator mode. The total running time refers to the time required for the refrigerator mode to run from setting to completion; the running time refers to the time the refrigerator mode has been running from setting to the present moment; and the remaining running time refers to the difference between the total running time and the running time in the current refrigerator mode.

[0047] The S5 dynamically sets the refrigerator mode based on information such as the current door opening interval, the average door opening interval, and the storage status of food volume.

[0048] Based on the refrigerator parameters and mode definitions described above, the cloud server can calculate the average door opening interval, seasonal weight vector, and food volume storage status of the current refrigerator. According to this information, the current refrigerator mode is dynamically set. The refrigerator modes include smart mode, quick-cooling mode, quick-freezing mode, and holiday mode. These names are just designations and may differ on different models; for example, holiday mode may be called travel mode on some refrigerators. Therefore, the refrigerator modes are not limited to these specific modes; any mode with similar functionality is included within the scope of this invention.

[0049] This invention provides a method for dynamically setting a refrigerator mode, as illustrated in the embodiments. Figure 2 and Figure 3 As shown, the specific method includes the following steps:

[0050] Determine whether the current door opening time difference of the refrigerator is less than the ratio of the average door opening time interval of the previous n times to the seasonal weight. If so, specifically, this includes... Figure 2 The method operation steps shown are as follows:

[0051] If the current door opening time difference is less than the ratio of the average door opening time interval of the previous n times to the seasonal weight, that is... Then determine the current storage status of the food in the refrigerator by volume.

[0052] If the refrigerator is currently at full capacity, check if it is set to a specific mode. If so, and it is set to quick cooling or quick freezing mode, then keep the refrigerator running in that mode until T. l After a certain time, set it to smart mode; otherwise, set the refrigerator to quick-cool or quick-freeze mode and run it. After a certain time, set it to smart mode.

[0053] If the current food storage status in the refrigerator is unsaturated, i.e., a small amount or a normal amount, then determine if the refrigerator is currently in a set mode. If so, keep the refrigerator in the current mode T. l After a certain time, set it to smart mode; otherwise, set the refrigerator directly to smart mode.

[0054] Determine whether the current door opening time difference of the refrigerator is less than the ratio of the average door opening time interval of the previous n times to the seasonal weight. If not, specifically, this includes... Figure 3 The method operation steps shown are as follows:

[0055] If the current door opening time difference is greater than or equal to the ratio of the average door opening time interval of the previous n times to the seasonal weight, that is... Then determine the current storage status of the food in the refrigerator by volume.

[0056] If the current food storage status in the refrigerator is a small quantity, i.e., V food<1 / 3V fridge If the refrigerator is currently in a set mode, then determine if it is in a holiday mode. If so, and the current mode is not holiday mode, then keep the refrigerator in the current mode T. l After a certain time, set it to holiday mode; if the refrigerator is currently in non-holiday mode or has no mode set, then set the refrigerator to holiday mode.

[0057] If the current food storage status in the refrigerator is normal, i.e., 1 / 3V fridge ≤V food <7 / 10V fridge If the refrigerator is currently set to a mode, then determine if the mode is a holiday mode. If it is a holiday mode, keep the refrigerator in holiday mode; otherwise, keep the refrigerator in the current mode T. l After a certain time, set it to holiday mode; otherwise, if the refrigerator is not currently set to a mode, maintain the current temperature until... After the time, set it to holiday mode.

[0058] If the current food storage state in the refrigerator is saturated, i.e., V food ≥7 / 10V fridge If so, determine whether the refrigerator is currently set to a mode. If so, determine whether the mode is quick cooling or quick freezing mode. The refrigerator will continue to maintain its current mode until... After a certain time, set to holiday mode; if it is quick-cooling or quick-freezing mode and The refrigerator will remain in its current mode T. l After a certain time, set to holiday mode; if the current mode is not quick-cooling or quick-freezing mode, or if the refrigerator has no mode set, then set the refrigerator to quick-cooling or quick-freezing mode and run it. After the time, set it to holiday mode.

[0059] In one specific implementation, taking the refrigerator compartment as an example, specifically, assuming that there were 11 openings in the three days prior to the last opening of the refrigerator compartment, and the total time interval between openings was 40 hours, then the average time interval between openings is 4 hours. If the seasonal pairwise comparison matrix we constructed is as follows:

[0060]

[0061] Then the four eigenvalues ​​of the seasonal pairwise comparison matrix can be obtained as 4.0042, 0, and -0.0021 (double roots). The eigenvector corresponding to the largest eigenvalue 4.0042 is [0.3085, 0.08852, 0.3085, 0.1616]. According to formula (5), the normalized eigenvector can be obtained as [0.1854, 0.5320, 0.1854, 0.0971]. Assuming the current season is spring, its seasonal weight is 0.1854, and the ratio of the average door opening time interval to the seasonal weight is 21.57. In addition, we assume that the volume of the refrigerator compartment is 300L.

[0062] If the current door opening time difference is 15 hours, and the sensor detects that the volume of food in the refrigerator compartment is 100L, and the refrigerator is currently in quick cooling mode (total running time is 5 hours) with 3 hours already run and 2 hours remaining, then the refrigerator should continue in quick cooling mode for another 2 hours before switching to smart mode.

[0063] One embodiment of the present invention provides a refrigerator operation mode control system, such as... Figure 4 As shown, it includes:

[0064] Refrigerator 100 includes a main control board 101 mounted on the refrigerator's base plate. This main control board records operational parameters, including the number of times the refrigerator door is opened and the opening time per unit time. Simultaneously, several infrared sensors 102 are installed inside the refrigerator compartment. These sensors detect the shape and size of food stored inside the compartment, thus determining the current volume of food stored in the refrigerator. Both the parameter information and the food volume information are uploaded to a cloud server 200.

[0065] The cloud server 200 is connected and communicates with the refrigerator 100. It receives information such as refrigerator operating parameters, food volume and seasonal pairing comparison matrix recorded by the main control board of the refrigerator 100. When executing the computer program, it can realize the steps in the refrigerator operating mode control method.

[0066] This invention also provides a storage medium storing a computer program. When the computer program is executed by a processor, it implements the steps in the refrigerator operation mode control method described above, that is, it implements the steps in any of the technical solutions of the refrigerator operation mode control method.

[0067] In summary, the refrigerator operation mode control method, system, and storage medium provided by this invention first collect and acquire parameter information such as the average door opening interval, number of door openings, and most recent door opening interval per unit time. Secondly, it constructs a seasonal pairwise comparison matrix by combining the influence of seasons on the refrigerator door opening interval, thereby obtaining a seasonal weight vector. Next, it uses infrared sensors in the refrigerator to detect the volume of food in each compartment, and accurately measures the saturation state of the food in the refrigerator by analyzing the food volume storage status. Finally, it dynamically sets the refrigerator mode based on the current door opening interval, the ratio of the average door opening interval to the seasonal weight, and the current food volume storage status. This control method not only maximizes the refrigerator's cooling effect when the user frequently opens the door and when there is a large amount of food in the refrigerator, but also saves electricity consumption and reduces unnecessary expenses for the user when the user does not open the door for a long time and when there is little food in the refrigerator.

[0068] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0069] The detailed descriptions listed above are merely specific descriptions of feasible implementations of the present invention and are not intended to limit the scope of protection of the present invention. All equivalent implementations or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
