Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment control, for example, to a method and device for controlling refrigeration equipment and refrigeration equipment. Background Art

[0002] Currently, refrigeration equipment is a key device for achieving cooling or freezing effects and is widely used in areas such as food preservation. For example, a refrigerator's primary function is to maintain an appropriate internal temperature to prolong the shelf life of food. However, although refrigerators are tested for their cooling capacity at the factory, their cooling rate can vary after delivery and use due to various factors. This variation in cooling rate has a significant impact on food preservation. Generally, if cooling takes too long, meat may remain at a higher temperature for a prolonged period before reaching the desired freezing point, increasing the risk of bacterial growth and affecting the safety and taste of the meat. Furthermore, if frozen meat experiences an excessive temperature rise due to factors such as poor refrigerator performance or frequent door opening and closing, the cellular structure of the food may be damaged during refreezing, resulting in a poor taste and loss of nutrients.

[0003] At present, a method for defrosting a refrigerator is disclosed in the relevant technology, and its specific implementation scheme is: obtaining the current ambient temperature of the refrigerator and the refrigeration gear set for the refrigerator; based on the refrigeration gear and the temperature range corresponding to the ambient temperature, determining the target temperature that the refrigerator needs to drop to during the pre-cooling process before performing the defrosting operation; based on the target temperature, controlling the refrigerator's compressor to perform pre-cooling.

[0035] Figure 1 This is a schematic diagram of a method for controlling a refrigeration device provided by an embodiment of the present disclosure; Figure 1 As shown, an embodiment of the present disclosure provides a method for controlling a refrigeration device, comprising:

[0036] S11, the refrigeration equipment obtains a temperature sequence of the freezing compartment within a preset time period.

[0037] S12, the refrigeration device selects a target continuous temperature sequence from the temperature sequence of the freezing compartment.

[0038] S13, the refrigeration equipment determines the target time according to the target continuous temperature sequence.

[0039] S14: When the current time reaches the target time, the refrigeration device controls the freezing compartment to operate at the target set temperature.

[0040] In this solution, refrigeration equipment is widely used in fields such as food preservation. Refrigeration equipment typically includes a series of components, such as a compressor, condenser, evaporator, and throttling device, which work together to complete the refrigeration cycle. Optionally, the refrigeration equipment includes refrigerators, freezers, and the like. Specifically, the refrigeration equipment can use its associated temperature sensor to obtain a temperature sequence of the freezer compartment over a preset time period. A freezer compartment temperature sequence is a collection of temperature values ​​that changes over time and is typically used to record the freezer compartment's temperature at different points in time. The preset time period is a historical period. As an example, the preset time period is 12 hours. Using this solution, by obtaining the freezer compartment temperature sequence over the preset time period, a comprehensive and accurate understanding of the freezer compartment's temperature changes during that time period can be obtained. This provides a reliable data foundation for subsequent screening and analysis.

[0041] Furthermore, the refrigeration device can filter out a target continuous temperature sequence from the freezer compartment's temperature sequence. Specifically, filtering out the target continuous temperature sequence from the freezer compartment's temperature sequence includes: removing abnormal data from the freezer compartment's temperature sequence to obtain a remaining temperature sequence; and filtering out the target continuous temperature sequence from the remaining temperature sequence. This solution, by filtering out the target continuous temperature sequence from the temperature sequence, helps identify the optimal cooling period for the freezer compartment within a preset time period, thereby more accurately understanding the freezer compartment's performance characteristics and optimal operating state.

[0042] Furthermore, after selecting the target continuous temperature sequence, the refrigeration device can determine a target time based on the target continuous temperature sequence. Specifically, the refrigeration device determines the target time based on the target continuous temperature sequence by: calculating the current cooling rate of the freezer compartment based on the target continuous temperature sequence; and determining the target time based on the current cooling rate of the freezer compartment. This solution can accurately determine the timing for adjusting the freezer compartment's set temperature, ensuring that the control strategy is implemented at the optimal time.

[0043] Furthermore, when the current time reaches the target time, the refrigeration device controls the freezer compartment to operate at the target set temperature. The target set temperature can be determined based on the refrigeration device's current set temperature and the freezer compartment's temperature fluctuation. Here, the refrigeration device's current set temperature refers to the freezer compartment's set temperature. This facilitates setting the refrigeration device's parameters according to the target set temperature at the target time.

[0044] The method for controlling refrigeration equipment provided by the disclosed embodiments obtains a freezer compartment temperature sequence within a preset time period, enabling a comprehensive and accurate understanding of the freezer compartment's temperature changes during that period. Filtering the temperature sequence to identify the optimal cooling period for the freezer compartment within the preset period allows for a more accurate understanding of the freezer compartment's performance characteristics. The target continuous temperature sequence is then combined to determine a target time, precisely determining the timing for pre-cooling the freezer compartment. At the target time, the freezer compartment is controlled to operate at the target set temperature, enabling precise pre-cooling of the freezer compartment in advance to offset an impending significant temperature rise. This solution not only enhances freezer compartment performance stability, improves energy efficiency, and increases equipment lifespan, but also optimizes the user experience and enhances the refrigerator's intelligence.

[0045] Figure 2 This is a schematic diagram of a method for screening a target continuous temperature sequence provided by an embodiment of the present disclosure; Figure 2 As shown, optionally, in S12, the refrigeration device selects a target continuous temperature sequence from the temperature sequence of the freezing compartment, including:

[0046] S21, the refrigeration device removes abnormal data from the temperature sequence of the freezing compartment to obtain a remaining temperature sequence.

[0047] S22: The refrigeration device selects a target continuous temperature sequence from the remaining temperature sequences.

[0048] Understandably, the freezer compartment temperature sequence may contain some abnormal data, which can interfere with the analysis and processing of the temperature sequence and even lead to erroneous conclusions. Therefore, in this case, before screening the target continuous temperature sequence, the abnormal data can be pre-filtered from the freezer compartment temperature sequence. Specifically, the refrigeration equipment removes abnormal data from the freezer compartment temperature sequence by: obtaining the freezer compartment door status sequence and the freezer compartment defrost heater status sequence; determining abnormal data based on the freezer compartment door status sequence and the freezer compartment defrost heater status sequence; and removing the abnormal data from the freezer compartment temperature sequence. This solution, by removing abnormal data, ensures that the remaining temperature sequence is more accurate and reliable, providing a foundation for subsequent analysis and processing.

[0049] Furthermore, the refrigeration device can filter out a target continuous temperature sequence from the remaining temperature sequences. Understandably, there may be multiple continuous temperature sequences in the remaining temperature sequences. However, not all temperature sequences are meaningful for adjusting the set temperature of the freezer compartment. Therefore, a target continuous temperature sequence that is meaningful can be sought. Specifically, filtering out the target continuous temperature sequence from the remaining temperature sequences includes: extracting multiple continuous temperature decrease sequences from the remaining temperature sequences; and selecting the sequence with the longest continuous temperature decrease duration among the multiple continuous temperature decrease sequences as the target continuous temperature sequence. By filtering out the target continuous temperature sequences, i.e., those with the longest continuous temperature decrease duration, we can better understand the performance characteristics and operating status of the freezer compartment.

[0050] Optionally, at S21, the refrigeration device removes abnormal data from the temperature sequence of the freezing compartment, including:

[0051] During a preset period of time, the refrigeration device obtains a state sequence of the freezer compartment door and a state sequence of the freezer compartment defrost heating wire.

[0052] The refrigeration equipment determines abnormal data according to the state sequence of the freezer compartment door and the state sequence of the freezer compartment defrost heating wire.

[0053] Refrigeration equipment removes abnormal data from the temperature series of the freezer compartment.

[0054] In this solution, the freezer door state sequence is a dataset that records the door's open and closed status over a preset time period. This state sequence allows users to visualize changes in the freezer door's open and closed status over that period. Specifically, the refrigeration appliance can use its associated door state sensor to monitor the door's open and closed status in real time over the preset period. Based on this state information, a freezer door state sequence is generated. This sequence is a time series data set that contains information about the door's open and closed status at different points in time. This solution enables accurate acquisition of the freezer door state sequence.

[0055] The freezer compartment defrost heater state sequence is a dataset that records the defrost heater's operating status at different points in time. This state sequence allows for visualization of the defrost heater's on / off status changes within a preset time period. Specifically, the refrigeration equipment can use its associated sensors to detect the defrost heater's on / off status in real time during the preset time period and, based on this status information, generate a freezer compartment defrost heater state sequence. This sequence is a time series data set that contains the defrost heater's on / off status information at different points in time. This approach enables accurate acquisition of the freezer compartment defrost heater state sequence.

[0056] Furthermore, the refrigeration equipment can determine abnormal data based on the freezer compartment door status sequence and the freezer compartment defrost heater status sequence. Specifically, the refrigeration equipment determines abnormal data based on the freezer compartment door status sequence and the freezer compartment defrost heater status sequence, including: determining the freezer compartment door opening and closing completion time based on the freezer compartment door status sequence; determining the freezer compartment defrost completion time based on the freezer compartment defrost heater status sequence; and determining abnormal data based on the freezer compartment door opening and closing completion time and the freezer compartment defrost completion time. This solution enables accurate determination of abnormal data.

[0057] Furthermore, the refrigeration equipment can remove abnormal data from the temperature series of the freezer compartment. This solution ensures that the remaining temperature series is more accurate and reliable by removing abnormal data, providing a basis for subsequent analysis and processing.

[0058] Optionally, the refrigeration device determines abnormal data based on a state sequence of the freezer compartment door and a state sequence of the freezer compartment defrost heating wire, including:

[0059] The refrigeration equipment determines the end time of opening and closing the freezer compartment door according to the state sequence of the freezer compartment door body.

[0060] The refrigeration equipment determines the end time of defrosting of the freezing compartment according to the state sequence of the defrosting heating wire of the freezing compartment.

[0061] The refrigeration equipment determines abnormal data based on the time when the freezer compartment door is opened and closed and the time when the freezer compartment defrost is completed.

[0062] In this solution, the refrigeration device determines the end time of opening and closing the freezer compartment door according to the state sequence of the freezer compartment door, including: when the refrigeration device determines the moment when the state of the freezer compartment door changes from open to closed in the state sequence of the freezer compartment door, the moment can be used as the end time of opening and closing the freezer compartment door.

[0063] Optionally, take the freezing compartment door state sequence captured within a preset time period as an example:

[0064] 2:45, TRUE; 2:46, TRUE; 2:47, TRUE; 2:48, FALSE; 2:49, FALSE.

[0065] If the preset duration is shorter than the preset time period, TRUE indicates the door is open, and FALSE indicates it is closed. This shows that in the freezer door state sequence, the door is open at 2:47 and closed at 2:48. Therefore, 2:48, when the door changes from open to closed, can be used as the end time of the freezer door opening and closing. This method allows for precise determination of the end time of the door opening and closing.

[0066] In this solution, the refrigeration equipment determines the end time of defrosting of the freezer compartment according to the state sequence of the defrosting heating wire of the freezer compartment, including: the refrigeration equipment determines the moment when the state of the defrosting heating wire changes from start to stop in the state sequence of the defrosting heating wire of the freezer compartment, and this moment can be used as the end time of defrosting of the freezer compartment.

[0067] Optionally, take the state sequence of the defrosting heating wire of the freezing compartment within a preset time as an example:

[0068] 0:34, TRUE; 0:35, TRUE; 0:36, TRUE; 0:37, FALSE; 0:38, FALSE.

[0069] If the preset duration is shorter than the preset period, TRUE indicates that the defrost heater is active, and FALSE indicates that it is inactive. This indicates that in the freezer compartment defrost heater state sequence, the defrost heater is active at 0:36 and inactive at 0:37. Therefore, the time at which the defrost heater changes from active to inactive at 0:37 can be used as the end time of freezer defrost. This solution allows for precise determination of the end time of freezer defrost.

[0070] Furthermore, the refrigeration equipment determines abnormal data based on the time when the freezer compartment door is opened and closed and the time when the freezer compartment defrost is completed, including:

[0071] The refrigeration device determines abnormal data based on the time when the freezer compartment door is opened and closed and the first time; and the refrigeration device determines abnormal data based on the time when the freezer compartment defrost is completed and the second time.

[0072] With this solution, accurate determination of abnormal data can be achieved.

[0073] Optionally, the refrigeration equipment determines abnormal data based on the freezer compartment door opening / closing time and the first time, including using the temperature data between the freezer compartment door opening / closing time and the first time as abnormal data. For example, if the freezer compartment door opening / closing time ends at 2:48 AM and the first time is 2:56 AM, the real-time temperature data from 2:48 AM to 2:56 AM is used as abnormal data. Here, the first time is the time when the set temperature is first reached after the door opening / closing time ends. Specifically, the first time is determined by obtaining the real-time temperature of the freezer compartment through a temperature sensor after the door opening / closing time ends. If the real-time temperature of the freezer compartment first reaches the set temperature, this time is used as the first time. This solution allows for accurate determination of the first time, providing a reliable data basis for abnormal data determination.

[0074] Optionally, the refrigeration device determines abnormal data based on the freezer compartment defrost completion time and a second time, including using the temperature data between the freezer compartment defrost completion time and the second time as abnormal data. For example, if the freezer compartment defrost completion time is 0:37 and the second time is 1:40, the real-time temperature data from 0:37 to 1:40 is used as abnormal data. Specifically, the second time is determined by obtaining the real-time temperature of the freezer compartment through a temperature sensor after the freezer compartment defrost completion time. If the real-time temperature of the freezer compartment reaches the set temperature for the first time, this time is used as the second time. This solution allows for accurate determination of the second time, providing a reliable data basis for determining abnormal data.

[0075] Figure 3 This is a schematic diagram of a method for determining a target continuous temperature sequence provided by an embodiment of the present disclosure; Figure 3 As shown, optionally, in S22, the refrigeration device filters out a target continuous temperature sequence from the remaining temperature sequences, including:

[0076] S31: The refrigeration device extracts a plurality of continuous temperature drop sequences from the remaining temperature sequences.

[0077] S32: The refrigeration device uses the sequence with the longest continuous temperature drop time among the multiple continuous temperature drop sequences as the target continuous temperature sequence.

[0078] In this solution, a continuous temperature drop sequence refers to a situation where the temperature value continues to drop within a certain period of time without rising or remaining unchanged. Alternatively, take the temperature sequence within a preset time period as an example:

[0079] 1:40, -19.3℃; 1:41, -19.7℃; 1:42, -19.9℃; 1:43, -19.8℃.

[0080] Among them, the preset time length is shorter than the preset time period, so it can be seen that the temperature continuously decreases from 1:41 to 1:42 in the temperature sequence. Therefore, 1:41 to 1:42 can be used as a continuous temperature decrease sequence.

[0081] The continuous temperature drop duration is the total time from the start of the temperature drop to the stop of the temperature drop in the sequence. Therefore, the refrigeration device can use the sequence with the longest continuous temperature drop duration among multiple continuous temperature drop sequences as the target continuous temperature sequence.

[0082] As an example, if six consecutive temperature-decreasing sequences are extracted from the remaining temperature sequences, including: 0:00 to 0:02, 1:41 to 1:42, 2:00 to 2:13, 2:25 to 2:27, 2:33 to 2:35, and 2:57 to 2:59, the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 0:00 to 0:02 is 2 minutes; the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 1:41 to 1:42 is 1 minute; the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 2:00 to 2:13 is 13 minutes; the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 2:25 to 2:27 is 2 minutes; the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 2:33 to 2:35 is 2 minutes; and the total time from the start of the temperature decrease to the stop of the temperature decrease in the sequence 2:57 to 2:59 is 2 minutes. From this, it can be seen that among the multiple continuous temperature drop sequences, the sequence from 2:00 to 2:13 has the longest continuous temperature drop time, so the sequence from 2:00 to 2:13 can be used as the target continuous temperature sequence. This solution can achieve accurate determination of the target continuous temperature sequence.

[0083] Figure 4 This is a schematic diagram of a method for determining a target time provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S13, the refrigeration device determines a target time according to the target continuous temperature sequence, including:

[0084] S41, the refrigeration device calculates the current cooling rate of the freezing compartment according to the target continuous temperature sequence.

[0085] S42: The refrigeration device determines a target time according to the current cooling rate of the freezing compartment.

[0086] In this solution, the refrigeration equipment can calculate the current cooling rate of the freezer compartment using various methods. In one example, a target continuous temperature sequence can be differentiated and the difference results can be averaged to determine the current cooling rate. Here, the difference calculation is calculated by subtracting the previous term from the next term in the target continuous temperature sequence. This solution can accurately determine the current cooling rate.

[0087] In another example, the refrigeration device can calculate the difference between the last item and the first item in the target continuous temperature sequence and divide the difference by the number of phases in the target continuous temperature sequence to obtain the current cooling rate. For example, the target continuous temperature sequence is -17°C, -17.2°C, -17.6°C, -17.9°C, -17.9°C, -18.2°C, -18.5°C, -18.8°C, -19°C, -19°C, -19.3°C, -19.6°C, -19.9°C, then the current cooling rate = (-19.9-(-17)) ÷ 13 = (-0.22308)°C / min. This solution can accurately determine the current cooling rate.

[0088] Furthermore, the refrigeration equipment can determine a target time based on the current freezer cooling rate. Specifically, this determination involves: obtaining door usage records for the refrigeration equipment; and determining the target time based on the door usage records and the current freezer cooling rate. This solution, which determines the target time based on the freezer cooling rate, not only enables precise control and optimizes energy consumption, but also extends equipment life and enhances user experience.

[0089] Optionally, in S42, the refrigeration device determines a target time according to a current cooling rate of the refrigeration device, including:

[0090] Refrigeration equipment obtains the door usage records of the refrigeration equipment.

[0091] The refrigeration equipment determines the target time based on the door usage record of the refrigeration equipment and the current cooling rate of the freezer compartment.

[0092] In this solution, refrigeration equipment can obtain door usage records. These records include door opening times and durations. In one example, door opening times lasting more than three seconds can be considered valid data. This solution facilitates accurate screening of valid door usage records.

[0093] Furthermore, the refrigeration device can determine the target time based on the door usage record and the current cooling rate of the freezer compartment. Specifically, the refrigeration device determines the target time based on the door usage record and the current cooling rate of the freezer compartment, including:

[0094] The refrigeration equipment estimates the time period when the user frequently uses the refrigeration equipment based on the door usage records of the refrigeration equipment;

[0095] The refrigeration equipment determines the target time based on the time period when the user frequently uses the refrigeration equipment, the temperature fluctuation value of the freezer compartment and the current cooling speed of the freezer compartment.

[0096] In one example, if the refrigeration device, based on door usage records, infers that the user frequently opens the refrigeration device door between 7:00 and 7:30 during breakfast time, then 7:00 to 7:30 is determined to be the time period when the user frequently uses the refrigeration device. This solution can accurately infer the time period when the user frequently uses the refrigeration device.

[0097] In this solution, the freezer compartment temperature fluctuation value refers to the range of change in the freezer compartment temperature over a set period of time. The freezer compartment temperature fluctuation value can be determined by analyzing temperature data collected by the refrigeration equipment's associated temperature sensors. As an example, the freezer compartment temperature fluctuation value is 2°C.

[0098] Specifically, the refrigeration device determines the target time based on the user's frequent use period, the temperature fluctuation value of the freezer compartment, and the current cooling rate of the freezer compartment, including:

[0099] The refrigeration equipment determines the pre-cooling time of the refrigeration equipment according to the temperature fluctuation value of the freezer compartment and the current cooling speed of the freezer compartment;

[0100] The refrigeration equipment uses the time period when the user frequently uses the refrigeration equipment and the pre-cooling time as the target time.

[0101] The refrigeration system can calculate the pre-cooling time by dividing the freezer compartment's temperature fluctuation by the freezer compartment's current cooling rate. For example, if the freezer compartment's temperature fluctuation is 2°C and the freezer compartment's current cooling rate is -0.22308°C / min, the pre-cooling time is calculated as: 2°C ÷ (-0.22308)°C / min ≈ 9 minutes. This approach allows for accurate calculation of the freezer compartment's pre-cooling time.

[0102] Furthermore, the refrigeration device determines the start time of frequent use based on the user's frequent use periods. The target time is then determined based on the start time and pre-cooling duration. For example, if the user frequently uses the refrigeration device from 7:00 to 7:30, the start time of frequent use is determined to be 7:00. Since the target time should be earlier than the start time of frequent use, 6:51, which is 9 minutes earlier, is used as the target time. This solution allows for precise determination of the target time.

[0103] Figure 5 This is a schematic diagram of a method for determining a target set temperature provided by an embodiment of the present disclosure; Figure 5 As shown, the target set temperature is determined by:

[0104] S51: The refrigeration device obtains the current set temperature of the refrigeration device and the temperature fluctuation value of the freezing compartment.

[0105] S52: The refrigeration device determines a target set temperature according to the current set temperature of the refrigeration device and the temperature fluctuation value of the freezing compartment.

[0106] In this solution, the freezer compartment temperature fluctuation value refers to the range of change in the freezer compartment temperature over a set period of time. This temperature fluctuation value can be determined by analyzing temperature data collected by the refrigeration equipment's associated temperature sensors. For example, the freezer compartment temperature fluctuation value is 2°C. Thus, the difference between the current set temperature and the fluctuation temperature can be used as the target set temperature. For example, if the freezer compartment temperature fluctuation value is 2°C and the current set temperature is -18°C, the target set temperature can be determined as (-18)°C - 2°C = (-20)°C. This solution allows for precise determination of the target set temperature.

[0107] In one optimized solution, if the current time reaches the user's frequent use of the refrigeration device, the refrigeration device is controlled to adjust the freezer compartment temperature back to the initial setting. This solution can restore the refrigeration device's cooling efficiency when the user frequently opens the refrigeration device door, meeting the user's energy-saving needs for the refrigeration device.
