[0025] The present invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0026] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance.

[0027] Currently, when most refrigeration equipment opens or closes the door, due to the exchange of internal and external airflows, temperature fluctuations are likely to occur, resulting in the refrigeration equipment quickly adjusting its operating frequency after closing the door, which may cause an increase in the overall machine noise and working load. Therefore, in terms of solving the problem of a large temperature fluctuation range when opening and closing the door, predicting the temperature change when the refrigeration equipment opens and closes the door and performing temperature compensation operations in advance has relatively important practical significance. Taking the smart refrigerator as an example, the present invention is of course also applicable to other refrigeration equipment.

[0028] Based on this, the present invention provides a method for adjusting the temperature of a refrigerator, as Figure 1 shown, specifically including the following steps:

[0029] Step S1, obtain and calculate the average door opening duration according to the operating parameters of the refrigerator within the sampling interval;

[0030] Step S2, determine the temperature change parameter in the refrigerator compartment and the total temperature compensation duration required to compensate for the temperature change parameter according to the average door opening duration;

[0031] Step S3, compensate the temperature in the refrigerator compartment before opening the door according to the temperature change parameter and the total temperature compensation duration.

[0032] In this way, by changing the stage of temperature adjustment in the refrigerator compartment and compensating the temperature of the refrigerator in advance, it is beneficial to reduce the temperature fluctuation caused by external heat entering the refrigerator when opening the door, reduce the impact of opening and closing the door on the temperature in the refrigerator compartment, and improve the user experience.

[0033] Among them, the sampling interval may refer to a certain past time period, such as one day, one week, or one month, etc. By using the historical sampling interval, the operating parameters of the refrigerator can be reviewed and analyzed to understand the usage situation of the refrigerator and the user's behavior pattern, which helps to accurately calculate the average door opening duration.

[0034] In addition, the operating parameters may include the number of times the refrigerator door is opened and the duration of the refrigerator door being open; the temperature change parameters may include the direction of temperature change and the amount or range of temperature change. Specifically, the number of times the refrigerator door is opened can reflect the usage frequency of the refrigerator, while the duration of the refrigerator door being open can reflect the length of time the refrigerator door is open. The direction of temperature change may refer to an increase or decrease in temperature, and the amount or range of temperature change can reflect the amplitude and speed of temperature change, thus helping to understand the operating conditions of the refrigerator.

[0035] In one embodiment, step S1 may specifically include the following steps:

[0036] Step S11, obtain and count the total number of times the refrigerator door is opened and the total duration of the refrigerator door being open within the sampling interval;

[0037] Step S12, calculate the average door opening duration based on the total number of times the refrigerator door is opened and the total duration of the refrigerator door being open; wherein, the average door opening duration is equal to the ratio of the total duration of the refrigerator door being open to the total number of times the refrigerator door is opened.

[0038] In this way, it helps to accurately understand the usage of the refrigerator and the user's behavior pattern. Only using statistical methods to determine the average door opening duration, the calculation method is simple and direct.

[0039] Furthermore, as Figure 2 shown, in another embodiment, the present invention provides refined steps for step S11, which may specifically include:

[0040] Step S111, obtain the current position information of the refrigerator;

[0041] Step S112, query the refrigerator door opening and closing rhythm knowledge base according to the position information to determine several groups of refrigerator door opening time points and door opening durations within the sampling interval;

[0042] Step S113, respectively count the total number of times the refrigerator door is opened and the total duration of the refrigerator door being open within the sampling interval based on the several groups of refrigerator door opening time points and the door opening durations, and calculate the total number of times the refrigerator door is opened and the total duration of the refrigerator door being open.

[0043] In this way, determining the sampling data within the sampling interval through the current position information of the refrigerator makes the collected data match the current external environment where the refrigerator is located, and has strong robustness and adaptability.

[0044] Among them, the location information of the refrigerator may directly affect its usage. When the refrigerator is in a cold environment, due to the low external temperature, users are more inclined to store food indoors or take other preservation measures, and the usage frequency of the refrigerator is relatively reduced. Correspondingly, the number of door openings and the duration of door openings of the refrigerator also decrease. On the contrary, when the refrigerator is in a hot environment, due to the high external temperature, users may use the refrigerator more frequently to store and retrieve food to keep the food fresh. Therefore, the number of door openings and the duration of door openings of the refrigerator are also relatively long.

[0045] In addition, the refrigerator door opening and closing rhythm knowledge base is a database containing the rules of the refrigerator door opening and closing rhythm. Specifically, by collecting the usage of the refrigerator by users in various regions of the country during the sampling period, including the door opening and closing times, frequencies, door opening and closing durations, etc., a large amount of sampling data is obtained; the sampling data is cleaned, sorted and analyzed to extract the rhythm rules of the refrigerator door opening and closing, and the characteristics of the refrigerator door opening and closing rhythm are obtained; according to the door opening and closing rhythm characteristics, the refrigerator door opening and closing rhythm knowledge base is constructed.

[0046] It should be emphasized that the acquisition of the refrigerator door opening and closing rhythm knowledge base is a continuous process, and data needs to be continuously collected and the knowledge base updated to meet the needs of different users and environments.

[0047] For example, as Figure 3 shown, with the region as the unique identifier, the refrigerator door opening and closing rhythm knowledge bases of different regions are constructed. The door opening and closing rhythm knowledge base may include the location information of the refrigerator, the door opening time points within the statistical sampling period (such as one day), and the average door opening duration (unit: minute). Of course, the refrigerator door opening and closing rhythm knowledge base is not limited to the fields shown in the figure, and the content of the knowledge base can be freely added or deleted according to actual needs, with good flexibility and scalability.

[0048] Based on the average door opening duration, estimate the temperature change in the refrigerator compartment when the door opening duration of the refrigerator lasts until the average door opening duration. Based on this, as Figure 4 shown, in the first embodiment, the refrigerator temperature adjustment method may include the following steps:

[0049] Step S1, obtain and calculate the average door opening duration according to the operating parameters of the refrigerator within the sampling period;

[0050] Step S21, based on the relationship model between the door opening duration and the temperature change amount, input the average door opening duration into the relationship model to simulate and calculate the temperature change parameters in the refrigerator compartment;

[0051] Step S22, according to the temperature change parameters, calculate the total temperature compensation duration required to complete the compensation of the temperature change parameters;

[0052] Step S3, compensate the temperature in the refrigerator compartment before opening the door according to the temperature change parameter and the total temperature compensation duration.

[0053] In this way, the temperature change parameters corresponding to different average door opening durations can be quickly and accurately estimated. The method is simple and easy to implement, and can effectively improve the temperature control accuracy and efficiency of the refrigerator.

[0054] Among them, the relationship model between the door opening duration and the temperature change amount is a mathematical model that describes the relationship between the temperature change in the refrigerator compartment and the door opening duration when the refrigerator is in the door-open state. This model aims to describe how the temperature changes over time when the refrigerator door is open through mathematical formulas or algorithms.

[0055] Of course, the influence of the average door opening duration on the temperature of the refrigerator compartment can also be detected and implemented through sensors. Specifically, configure a timer for the average door opening duration; when receiving the control signal sent by the timer, determine the data value detected by the temperature sensor in the refrigerator compartment as the temperature change parameter; construct the mapping relationship between the average door opening duration and the temperature change parameter, and save it to the knowledge base. Therefore, any method for predicting or calculating the temperature change in the refrigerator compartment based on the average door opening duration is included within the protection scope of the present invention and will not be specifically elaborated herein.

[0056] Further, when the refrigerator is operating normally, step S22 may specifically include the following steps:

[0057] Step S221, analyze the influence of the temperature change parameter on the refrigerator temperature control, and determine the temperature change amount and the temperature compensation method according to the analysis result; wherein, the temperature compensation method includes turning on or off the compressor;

[0058] Step S222, calculate the total temperature compensation duration required to compensate the temperature change parameter according to the temperature change amount and the temperature compensation method.

[0059] In this way, by analyzing the temperature change parameter to determine the temperature compensation strategy, precise temperature control of the refrigerator can be achieved, and the working efficiency of the refrigerator can be improved.

[0060] Among them, the temperature change amount can be positive or negative. When the temperature of the external environment of the refrigerator is lower than the temperature in the refrigerator compartment, it is predicted that when the refrigerator door is opened, cold air from the outside will enter the refrigerator, which may cause the temperature in the refrigerator compartment to drop. At this time, the temperature change amount is negative, and the corresponding temperature compensation method is to turn off the compressor and stop refrigeration. When the temperature of the external environment of the refrigerator is higher than the temperature in the refrigerator compartment, it is predicted that when the refrigerator door is opened, hot air from the outside will enter the refrigerator, which may cause the temperature in the refrigerator compartment to rise. At this time, the temperature change amount is positive, and the corresponding temperature compensation method is to turn on the compressor and continue refrigeration.

[0061] It should be emphasized that the temperature compensation operation means that the compressor continuously operates at the normal working frequency for the total temperature compensation duration, so that the temperature in the refrigerator compartment is gradually adjusted to the set target temperature value. That is, a longer working duration (using the normal working frequency) is used in advance to replace a higher working frequency and reduce noise.

[0062] According to the temperature change amount and the total temperature compensation duration, the latest time for the refrigerator to execute the temperature compensation method can be determined, so as to ensure that there is little or no fluctuation in the temperature in the refrigerator compartment after the door is opened.

[0063] As Figure 5 shown, in one embodiment, the operating parameters of the refrigerator may include several door opening time points. Based on this, step S3 may specifically include the following steps:

[0064] Step S31, according to the several door opening time points and the total temperature compensation duration, calculate several start compensation time points for adjusting the temperature in the refrigerator compartment respectively;

[0065] Step S32, using the temperature change amount as the compensation amplitude value, control the refrigerator compressor to perform the temperature compensation operation at the normal working frequency at each start compensation time point until the compensation operation time reaches the total temperature compensation duration.

[0066] In this way, by completing the temperature compensation operation in the refrigerator compartment in advance, the temperature fluctuation when the refrigerator door is opened and closed can be reduced, the freshness and taste of food can be better maintained, and the user experience effect can be improved.

[0067] Among them, the time length between the door opening time point and the start compensation time point is the total temperature compensation duration. The start compensation point can be understood as the latest start compensation moment. In other words, the start compensation point is the last time point when the refrigerator performs the early temperature compensation operation. From this time point, the refrigerator will start the temperature compensation operation, and by adjusting the operating state or working duration of the compressor and other means, the temperature in the refrigerator compartment will gradually return to the set target value. The start compensation point can ensure that before the refrigerator door is opened, the refrigerator can reach a relatively stable temperature state, thereby reducing the temperature fluctuation caused by the influence of the external environment after the door is opened and improving the user experience.

[0068] In addition, there can be multiple start compensation time points. The early temperature compensation operation is performed respectively according to the multiple door opening time points stored in the refrigerator door opening rhythm knowledge base, so as to ensure that no matter when the door is opened, the temperature in the refrigerator does not fluctuate greatly.

[0069] The above-mentioned multiple embodiments, examples or specific examples provided by the present invention can be combined with each other, so as to finally form multiple more optimal embodiments.

[0070] For example, as Figure 6 shown, taking North China as an example, according to the refrigerator door opening and closing rhythm knowledge base, it is known that the number of door openings in a day is three times in the morning, at noon and in the evening, and the opening duration each time is 1 minute, so the average opening duration is 1 minute. Based on the relationship model between the opening duration and the temperature change amount, it is simulated and calculated that the temperature in the refrigerator compartment may rise by about 1°C. The total temperature compensation duration required to complete the compensated rise of 1°C is about 5 minutes. According to the morning door opening time recorded in the refrigerator door opening and closing rhythm knowledge base is 07:00, the server sends a command to lower the gear by 1°C 5 minutes in advance (that is, 06:55 in North China) (assuming that the target temperature in the refrigerator compartment before the adjustment is -18°C), and the temperature in the refrigerator compartment drops by 1°C (the target temperature in the refrigerator compartment after the adjustment is -19°C). At 07:00, when the user opens and closes the door, the temperature rise value in the compartment is the temperature before the adjustment (that is, -18°C), so as to reduce the temperature fluctuation when opening and closing the door.

[0071] The present invention also provides a refrigerator temperature adjustment system, including: a memory for storing executable instructions; a processor for implementing the steps of any of the above-mentioned refrigerator temperature adjustment methods when running the executable instructions stored in the memory.

[0072] The present invention also provides a refrigeration device, including: a memory for storing executable instructions; a processor for implementing the steps of any of the above-mentioned refrigerator temperature adjustment methods when running the executable instructions stored in the memory.

[0073] To summarize, the present invention is based on the refrigerator door opening and closing rhythm knowledge base to determine the average door opening time of the refrigerator within the sampling interval, and according to the average door opening time, predicts in advance the change parameters of the indoor temperature of the refrigerator and the total temperature compensation time required to compensate for the temperature change parameters, and calculates the start time of the temperature compensation operation in advance according to the user's door opening time point within the sampling interval. This can ensure that the refrigerator can reach a relatively stable temperature state before the refrigerator door is opened, thereby reducing the temperature fluctuation caused by the influence of the external environment after the door is opened, better maintaining the freshness and taste of the food, and improving the user experience.

[0074] In addition, the compressor is controlled in advance to operate at a normal operating frequency for the total temperature compensation time, so that the temperature in the refrigerator compartment gradually returns to the set target value, and the influence of the temperature fluctuation of the door opening and closing is avoided by increasing the operating frequency of the compressor in a short period of time, thereby reducing the noise of the refrigerator as a whole and extending the service life of the refrigerator.

[0075] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
