Detailed ways

This embodiment firstly provides a refrigeration control device for a refrigerator, which can control the opening time of the refrigeration system of the refrigerator, and avoid turning on the refrigeration system during the period when the user frequently opens the door or when it is close to this period, effectively preventing the refrigeration system in the storage room of the refrigerator. reduce the energy consumption of the refrigerator. Fig. 1 is a refrigerator control block diagram suitable for a refrigerator refrigeration control device 100 according to an embodiment of the present invention.

Fig. 2 is a schematic block diagram of a refrigeration control device 100 for a refrigerator according to an embodiment of the present invention. 30.

Among the above modules, the time period acquiring module 10 can be configured to acquire the time period when the number of refrigerator door openings exceeds a preset threshold, and the number of refrigerator door openings is obtained according to statistics of refrigerator door opening and closing records. For example, based on the statistics of the door opening and closing records of the refrigerator in the previous month, the three time periods in which the number of refrigerator door openings are ranked from high to low and the corresponding door opening times are: 18:00 to 18:20, 26 times; 18:20 to 18:40, 23 times; 08:00 to 08:20, 20 times, if the preset threshold is 22 times, the eligible time periods are: 8:00 to 18:20 and 18:20 to At 18:40, it can be considered that these two time periods are the time periods when the user frequently opens the refrigerator door.

The time acquiring module 20 may be configured to acquire the operating time of the refrigerator.

The cooling control module 30 may be configured to determine whether the running time is within the time period or whether the time from the running time to the start of the time period is less than a first preset time threshold, and if any of the above determination results are yes, the refrigeration system 102 of the refrigerator is disabled. On until the end of the time period. For example, the time period when the number of door openings of the refrigerator exceeds the preset threshold is from 12:00 to 12:20 every day, and the operating time of the refrigerator is 12:10. Since the operating time 12:10 is within the time period from 12:00 to 12:20 Therefore, it is necessary to prohibit the refrigeration system 102 of the refrigerator from being turned on until the end of the time period at 12:20, so as to avoid turning on the refrigeration system 102 when the user frequently opens the door or when it is close to this period, so as to effectively prevent the loss of cooling capacity in the storage room of the refrigerator. Reduce refrigerator energy consumption. The above-mentioned period of time during which the number of refrigerator door openings exceeds the preset threshold can be obtained according to the statistics of refrigerator door opening and closing records, and the above-mentioned numerical values are only examples and not specific limitations of the present invention.

The refrigeration control device 100 of the refrigerator in this embodiment obtains the time period when the refrigerator door is opened more than a preset threshold and the running time of the refrigerator; judges whether the running time is within the time period or the time from the running time to the starting point of the time period Whether it is less than the first preset time threshold, and in the case of any of the above judgment results being yes, the refrigeration system 102 of the refrigerator is prohibited from opening until the end of the time period, and the opening time of the refrigerator refrigeration system 102 is controlled to avoid frequent opening of the door by the user. Turn on the refrigeration system 102 at or near this time period, effectively prevent the loss of cooling capacity in the storage room of the refrigerator, reduce the energy consumption of the refrigerator, make the refrigeration control method of the refrigerator more intelligent and reasonable, and improve the user experience.

Fig. 3 is a schematic block diagram of a refrigeration control device 100 for a refrigerator according to another embodiment of the present invention. On the basis of the previous embodiment, the refrigeration control device 100 for a refrigerator may further include a door detection module 40, a counting module 50, The update module 60 and the state detection module 70 .

Wherein, the door detection module 40 may be configured to detect a door opening and closing event of the refrigerator.

The counting module 50 may be configured to divide the timing period into multiple statistical time periods, set a corresponding counter for each statistical time period, and perform counting in the corresponding counter according to the moment when the door opening and closing event occurs. The timing period can be one day or one week. For example, when the timing cycle is one day, you can set 72 statistical time periods in units of 20 minutes per day, which are: 00:00 to 00:20, 00:20 to 00:40, ..., 23:20 to 23 :40, 23:40 to 00:00. A corresponding counter is set for each statistical time period, that is, a total of 72 counters are set. Count in the corresponding counter according to the time when the door opening and closing event occurs. For example, when the opening and closing event occurs at 08:10, then add 1 to the counter corresponding to the time period from 08:00 to 08:20. For another example, when the timing cycle is one week, 504 statistical time periods can be set in units of 20 minutes per week, which are: Monday 00:00 to 00:20, 00:20 to 00:40...23:20 to 23:40, 23:40 to 00:00; ...; Sunday 00:00 to 00:20, 00:20 to 00:40 ... 23:20 to 23:40, 23:40 to 00:00. A corresponding counter is set for each statistical time period, that is, a total of 504 counters are set. Count in the corresponding counter according to the time when the door opening and closing event occurs. For example, when the door opening and closing event occurs at 08:10 on Wednesday, the counter corresponding to the time period from 08:00 to 08:20 on Wednesday is counted up by 1. Since Saturday and Sunday are rest days, the number of times the user opens the refrigerator door may be more than that on weekdays, and the number of times the user opens the refrigerator door at the same time on weekends and weekdays may be quite different. Therefore, when the timing cycle is one week, The user's habit of using the refrigerator can be recorded more accurately.

The record update module 60 may be configured to update the door opening and closing record of the refrigerator according to the count value of the counter in each statistical period after a preset statistical period, wherein each statistical period includes a preset number of timing periods. For example, the preset statistical period can be one month and the timing period is one day, then each statistical period contains 30 timing periods; another example is the preset statistical period is four weeks, and the timing period is one week, then each statistical period contains 4 tick cycle.

The record update module 60 can also be configured to: determine whether the number of timing periods in which door opening and closing events occur in the statistical period is less than the preset timing period threshold; and if not, set the count value in the statistical period as valid, and use the statistics The count value in the cycle will update the door opening and closing records, if so, the count value in the statistical cycle will be set as invalid, and the previous door opening and closing records will be kept. For example, the statistical period is one month, and the timing period is one day. If the number of days in which door opening and closing events occur in this month is 10 days, which is less than the preset timing period threshold of 15 days, the count value in this month will be set as invalid and reserved. Door opening and closing records for the last month. If the number of days with door opening and closing events in this month is 29 days, which is greater than the preset timing cycle threshold of 15 days, the count value in this month will be set as valid, and the count value in this month will be used to record the door opening and closing in the previous month to update. The length of the above timing period and statistical time period, the preset number of counting periods included in the statistical period, and the value of the preset counting period threshold can all be set according to the specific use environment and control objectives, and the above specific values are only examples.

The record update module 60 can also be configured to: sort each statistical time period in the statistical period according to the count value from high to low to obtain the first statistical time period sequence; Sort from high to low to obtain the second statistical time period sequence; match the first statistical time period sequence and the first statistical time period sequence in the second statistical time period sequence to determine the first statistical time period sequence and The same number of statistical time periods sorted earlier in the second statistical time period sequence; and if the same number of statistical time periods sorted earlier exceeds the preset value, the count value in the statistical cycle and the door switch record The counting values are merged to obtain a new door opening and closing record. If the number of the same number of statistical time periods ranked first is less than or equal to the preset value, the counting value in the statistical period will replace the counting value in the door opening and closing record to Get a new record of opening and closing doors.

For example, if the statistical period is one month and the timing period is one day, sort the statistical time periods in this month according to the count value from high to low, and the sequence of the first statistical time period is as follows: 08:00 to 08:20, 18: 00 to 18:20, 12:00 to 12:20, 18:20 to 18:40, 08:20 to 08:40, 19:00 to 19:20, 12:20 to 12:40, 18:40 to 19:00, 12:40 to 13:00, 20:00 to 20:20..., sort each statistical time period in the door opening and closing record in the previous month according to the count value from high to low, and get the second statistical time period sequence As follows: 08:00 to 08:20, 18:20 to 18:40, 08:20 to 08:40, 20:40 to 21:00, 08:40 to 09:00, 20:00 to 20:20, 18:00 to 18:20, 12:00 to 12:20, 19:00 to 19:20, 12:20 to 12:40..., due to the sorting in the first statistical time period sequence and the second statistical time period sequence The number of the same number in the first 10 statistical time periods is 8. If it exceeds the preset value of 6, it is considered that the user's habit of opening the refrigerator has not changed much. Therefore, the count value in this month can be compared with the record of door opening and closing in the previous month. The count values in are merged to get a new record of opening and closing doors. Specifically, for example, the count value of the time period from 08:00 to 08:20 this month is 24, and the count value of the time period from 08:00 to 08:20 in the door opening and closing records of last month is 26, calculate (24+26)/2 If 25 is obtained, then the count value of 25 in the time period from 08:00 to 08:20 can be used as a new door opening and closing record. If the number of identical numbers among the top 10 statistical time periods in the first statistical time period sequence and the second statistical time period sequence is 3, which is less than the preset value of 6, it can be considered that the user’s habit of opening the refrigerator has changed relatively quickly. The count value of this month can be replaced with the count value in the door opening and closing records to obtain a new door opening and closing record.

The state detection module 70 can be configured to detect the operating state of the refrigeration system 102 of the refrigerator, and obtain the running time of the refrigerator when the refrigeration system 102 is closed; Whether the difference ΔT of the fixed temperature is less than the first preset temperature value A1, if so, control the refrigeration system to turn off, if not, keep the refrigeration system on until the condition of ΔT<A1 is met. The refrigeration system 102 of the refrigerator is generally a system with a compressor as the main component, which can generate cold energy for the storage compartment of the refrigerator and reduce the temperature of the compartment. If the refrigerator is an air-cooled refrigerator, the refrigeration system 102 may further include a fan, which can send the cooling generated by the compressor to the storage compartment of the refrigerator.

The refrigeration control module 30 in this embodiment can also be configured to: when the time from the running time to the start point of the time period is greater than the second preset time threshold, determine the difference between the detected temperature of the compartment of the refrigerator and the set temperature of the compartment. Whether the difference is greater than the first preset temperature value, and when the judgment result is yes, the control refrigeration system 102 is turned on, wherein the second preset time threshold is greater than the first preset time threshold; When the time is less than or equal to the second preset time threshold, execute the step of judging whether the running time is within the time period or whether the time from the running time to the starting point of the time period is less than the first preset time threshold; When the time of the starting point of the segment is less than the second preset time threshold but greater than the first preset time threshold, it is judged whether the difference between the detected temperature of the compartment of the refrigerator and the set temperature of the compartment is greater than the second preset temperature value, And when the judgment result is yes, the refrigeration system 102 is controlled to be turned on, wherein the second preset temperature value is greater than the first preset temperature value.

For example, when the statistical period is one month and the timing period is one day, the time period when the number of door openings of the refrigerator exceeds the preset threshold is from 12:00 to 12:20 every day. The time from :00 to 12:00, the starting point of the time period, is 3 hours, which is greater than the second preset time threshold of 2 hours. It is judged that the difference ΔT between the detected temperature of the refrigerator’s compartment of 10 degrees Celsius and the set temperature of the compartment of 6 degrees Celsius is 4 Celsius, which is 2 degrees Celsius higher than the first preset temperature value. Therefore, it is necessary to control the refrigeration system 102 to start. Since the operating time is much earlier than the time period when the user frequently opens the refrigerator door, the temperature of the refrigerator compartment is strictly required. If the difference ΔT between the detected temperature of the compartment and the set temperature of the compartment is greater than the first preset temperature value, it is considered that the compartment temperature of the refrigerator needs to be lowered, and the refrigeration system 102 needs to be controlled to start, so as to reduce the compartment temperature in time to avoid overheating of the compartment. High and affect the storage effect.

If the operating time of the refrigerator is 11:30, since the time from the operating time 11:30 to the starting point of the time period 12:00 is 30 minutes, which is less than the second preset time threshold of 2 hours, it is determined that the operating time is from 11:30 to the time The time at the starting point of the segment at 12:00 is 30 minutes, which is less than the first preset time threshold of 1 hour. Therefore, it is considered that the user is about to open the door of the refrigerator. 102 is turned on.

If the operating time of the refrigerator is 10:30, since the time from the operating time 10:30 to the start point of the time period 12:00 is 1.5 hours, it is less than the second preset time threshold of 2 hours but greater than the first preset time threshold of 1 hour , it is judged that the difference ΔT between the detection temperature of the refrigerator’s compartment of 12 degrees Celsius and the set temperature of the compartment of 6 degrees Celsius is 6 degrees Celsius, which is greater than the second preset temperature value of 5 degrees Celsius. Therefore, it is necessary to control the refrigeration system 102 to start. The time period for opening the door of the refrigerator is relatively close, so the requirements for the temperature of the refrigerator compartment are relatively loose. When the difference ΔT between the detected temperature of the refrigerator compartment and the set temperature of the compartment is greater than the second preset temperature value, the refrigerator compartment is considered to be The room temperature needs to be lowered and the refrigeration system 102 needs to be turned on.

It should be noted that all the above numerical values are only examples and not specific limitations to the present invention.

The refrigeration control device 100 of the refrigerator in this embodiment obtains the time period when the refrigerator door is opened more than a preset threshold and the running time of the refrigerator; judges whether the running time is within the time period or the time from the running time to the starting point of the time period Whether it is less than the first preset time threshold, and in the case of any of the above judgment results being yes, the refrigeration system 102 of the refrigerator is prohibited from opening until the end of the time period, and the opening time of the refrigerator refrigeration system 102 is controlled to avoid frequent opening of the door by the user.

Further, the refrigerator cooling control device 100 of this embodiment divides the timing cycle into a plurality of statistical time periods, and sets a corresponding counter for each statistical time period; Counting is performed in the corresponding counter at the time of each statistical period. After the preset statistical period, the refrigerator’s door opening and closing records are updated according to the counting value of the counter in each statistical period, which can make the refrigerator’s door opening and closing records more accurate and more reflective. The user's usage habits make the refrigeration control method of the refrigerator more scientific, and more accurately control the opening time of the refrigeration system 102, so as to avoid the loss of cooling capacity in the storage room of the refrigerator and further improve the user's experience.
