图2是根据本发明一个实施例的冰箱的制氮控制装置100的示意框图,如图所示,冰箱的制氮控制装置100一般性地可以包括时间段获取模块10、时刻获取模块20、制氮控制模块30。2 is a schematic block diagram of a nitrogen-making control device 100 for a refrigerator according to an embodiment of the present invention. As shown, the nitrogen-making control device 100 of the refrigerator may generally include a time period acquisition module 10, a time acquisition module 20, and a system. Nitrogen control module 30.
在以上模块中,时间段获取模块10可以配置成获取冰箱密封空间开启 次数超过预设阈值的时间段,冰箱密封空间开启次数根据密封空间的开关记录统计得出。例如由上月的密封空间的开关记录统计得出,密封空间开启次数由高到低排序靠前的三个时间段及对应开启次数分别为:18:00至18:20,26次;18:20至18:40,23次;08:00至08:20,20次,若预设阈值为22次,则符合条件的时间段为:8:00至18:20和18:20至18:40,可以认为这两个时间段是用户频繁开启密封空间的时间段。预设阈值的数值可以根据具体的使用环境以及控制目标进行设置,上述具体数值仅为举例说明。In the above module, the time period obtaining module 10 can be configured to obtain the sealed space of the refrigerator. When the number of times exceeds the preset threshold, the number of times the refrigerator seal space is opened is counted according to the switch record of the sealed space. For example, from the switch records of the sealed space last month, it is concluded that the three times of the number of times the sealed space is opened from high to low and the corresponding 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 18: 40. It can be considered that these two time periods are the time periods during which the user frequently opens the sealed space. The value of the preset threshold can be set according to the specific use environment and the control target. The above specific values are only examples.
时刻获取模块20可以配置成获取冰箱的运行时刻。The time acquisition module 20 can be configured to obtain the runtime of the refrigerator.
制氮冷控制模块30可以配置成判断运行时刻是否位于时间段内或者运行时刻至时间段的起始点的时间是否小于第一预设时间阈值,若以上任一判断结果为是,禁止冰箱的制氮装置102开启直至时间段结束。例如密封空间开启次数超过预设阈值的时间段为每天的12:00至12:20,冰箱的运行时刻为12:10,由于运行时刻12:10位于时间段12:00至12:20内,因而要禁止冰箱的制氮装置102开启直至时间段结束点12:20,避免在用户开启密封空间频繁的时段或临近该时段时开启制氮装置102,有效防止密封空间内的氮气流失,降低冰箱能耗。The nitrogen-cooling control module 30 can be configured to determine whether the running time is within the time period or the time from the running time to the starting point of the time period is less than the first preset time threshold. If any of the above determination results is yes, the system of the refrigerator is prohibited. The nitrogen unit 102 is turned on until the end of the time period. For example, the time period when the number of times the sealed space is opened exceeds the preset threshold is 12:00 to 12:20 every day, and the running time of the refrigerator is 12:10. Since the running time is 12:10, the time is from 12:00 to 12:20. Therefore, the nitrogen generator 102 of the refrigerator is prohibited from being turned on until the end of the time period is 12:20, so as to prevent the nitrogen generating device 102 from being opened when the user opens the sealed space frequently or close to the time period, thereby effectively preventing nitrogen loss in the sealed space and reducing the refrigerator. Energy consumption.
本实施例的冰箱的制氮控制装置100,其中,冰箱的储物间室内部设置有密封空间,并且冰箱设置有用于向密封空间提供氮气的制氮装置,该冰箱的制氮控制装置100通过获取密封空间开启次数超过预设阈值的时间段与冰箱的运行时刻;判断运行时刻是否位于时间段内或者运行时刻至时间段的起始点的时间是否小于第一预设时间阈值,并在以上任一判断结果为是的情况下,禁止冰箱的制氮装置开启直至时间段结束,控制冰箱制氮装置的开启时间,避免在用户开启密封空间频繁的时段或临近该时段时开启制氮装置,有效防止密封空间内的氮气流失,降低冰箱能耗,冰箱的制氮控制方法更加智能合理,提高用户使用体验。In the nitrogen control apparatus 100 of the refrigerator of the present embodiment, the inside of the storage compartment of the refrigerator is provided with a sealed space, and the refrigerator is provided with a nitrogen generating device for supplying nitrogen to the sealed space, and the nitrogen generating control device 100 of the refrigerator passes Obtaining a time period in which the number of times the sealed space is opened exceeds a preset threshold and a running time of the refrigerator; determining whether the running time is within a time period or whether the time from the running time to the starting point of the time period is less than a first preset time threshold, and If the result of the determination is yes, the nitrogen-making device of the refrigerator is prohibited from being turned on until the end of the time period, and the opening time of the nitrogen-making device of the refrigerator is controlled to avoid opening the nitrogen-producing device when the user opens the sealed space frequently or near the time period, effectively Preventing the loss of nitrogen in the sealed space and reducing the energy consumption of the refrigerator. The nitrogen control method of the refrigerator is more intelligent and reasonable, and improves the user experience.
图3是根据本发明另一个实施例的冰箱的制氮控制装置100的示意框图,在上一实施例的基础上,冰箱的制氮控制装置100还可以包括空间检测模块40、计数模块50、记录更新模块60以及状态检测模块70。3 is a schematic block diagram of a nitrogen-making control device 100 for a refrigerator according to another embodiment of the present invention. On the basis of the previous embodiment, the nitrogen-making control device 100 of the refrigerator may further include a space detecting module 40, a counting module 50, The update module 60 and the status detection module 70 are recorded.
其中,空间检测模块40可以配置成检测密封空间的开关事件,可以通过检测密封空间的开闭信号来检测密封空间的开关事件。The space detecting module 40 may be configured to detect a switching event of the sealed space, and may detect a switching event of the sealed space by detecting an opening and closing signal of the sealed space.
计数模块50可以配置成将计时周期划分为多个统计时间段,并为每个 统计时间段设置对应的计数器,并根据开关事件发生的时刻在对应的计数器内进行计数。计时周期可以为一天,也可以为一周。例如在计时周期为一天时,可以将每天以20分钟为单位设置72个统计时间段,分别为:00:00至00:20、00:20至00:40、……、23:20至23:40、23:40至00:00。为每个统计时间段设置对应的计数器,即共设置72个计数器。根据开关事件发生的时刻在对应的计数器内进行计数,例如开关事件发生的时刻为08:10,则在08:00至08:20的时间段对应的计数器内计数加1。再例如在计时周期为一周时,可以将每周以20分钟为单位设置504个统计时间段,分别为:周一00:00至00:20、00:20至00:40……23:20至23:40、23:40至00:00;……;周日00:00至00:20、00:20至00:40……23:20至23:40、23:40至00:00。为每个统计时间段设置对应的计数器,即共设置504个计数器。根据开关事件发生的时刻在对应的计数器内进行计数,例如开关事件发生的时刻为周三08:10,则在周三08:00至08:20的时间段对应的计数器内计数加1。由于周六、周日为休息日,用户开启密封空间的次数可能较工作日会增加,周末与工作日的同一时刻用户开启密封空间的次数可能差别较大,因而计时周期为一周时,可以更加精确地记录用户使用冰箱密封空间的习惯。The counting module 50 can be configured to divide the timing period into a plurality of statistical time periods, and for each The corresponding time counter is set in the statistical time period, and is counted in the corresponding counter according to the time when the switching event occurs. The timing period can be one day or one week. For example, when the time period is one day, 72 statistical time periods can be set in units of 20 minutes per day, respectively: 00:00 to 00:20, 00:20 to 00:40, ..., 23:20 to 23 : 40, 23:40 to 00:00. Set the corresponding counter for each statistical time period, that is, set a total of 72 counters. The count is performed in the corresponding counter according to the time when the switch event occurs. For example, when the switch event occurs at 08:10, the count in the counter corresponding to the time period from 08:00 to 08:20 is incremented by one. For example, when the time period is one week, 504 statistical time periods can be set in units of 20 minutes per week, respectively: 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. The count is performed in the corresponding counter according to the time when the switch event occurs. For example, the time when the switch event occurs is 08:10 on Wednesday, and the count in the counter corresponding to the time period from 08:00 to 08:20 on Wednesday is incremented by one. Since Saturday and Sunday are rest days, the number of times users open the sealed space may increase compared with the working day. The number of times the user opens the sealed space at the same time on weekends and working days may vary greatly. Therefore, the time period is one week, which can be more Accurately record the user's habit of using the refrigerator to seal the space.
记录更新模块60可以配置成在经过预设的统计周期后,按照每个统计时间段的计数器的计数值更新密封空间的开关记录,其中每个统计周期包含预设个数的计时周期。例如预设的统计周期可以为一个月,计时周期为一天,则每个统计周期包含30个计时周期;再例如预设的统计周期为四周,计时周期为一周,则每个统计周期包含4个计时周期。The record update module 60 may be configured to update the switch record of the sealed space according to the count value of the counter of each statistical time period after a preset statistical period, wherein each statistical period includes a preset number of time periods. For example, the preset statistical period may be one month, and the timing period is one day, and each statistical period includes 30 timing periods; for example, the preset statistical period is four weeks, and the timing period is one week, and each statistical period includes four. Timing period.
记录更新模块60还可以配置成:判断统计周期内出现开关事件的计时周期的个数是否少于预设计时周期阈值;以及若否,将统计周期内的计数值设为有效,并利用统计周期内的计数值对开关记录进行更新,若是,将统计周期内的计数值设为无效,并保留之前开关记录。例如统计周期为一个月,计时周期为一天,若本月内出现开关事件的天数为10天,少于预设计时周期阈值15天,则将本月内的计数值设为无效,并保留上月的开关记录。若本月内出现开关事件的天数为29天,大于预设计时周期阈值15天,则将本月内的计数值设为有效,并利用本月内的计数值对上月的开关记录进行更新。以上计时周期以及统计时间段的长度、统计周期包含计时周期的预设个数、预设计数周期阈值的数值均可以根据具体的使用环境以及控制目标进行 设置,上述具体的数值仅为举例说明。The record update module 60 may be further configured to: determine whether the number of time periods in which the switch event occurs in the statistical period is less than a preset time period threshold; and if not, set the count value in the statistical period to be valid, and use the statistical period The count value in the update updates the switch record, and if so, the count value in the statistical period is set to invalid, and the previous switch record is retained. For example, the statistical period is one month, and the counting period is one day. If the number of days in which the switching event occurs within this month is 10 days, less than the preset timing period threshold of 15 days, the count value in this month is invalidated and retained. Month's switch record. If the number of days when the switch event occurs within this month is 29 days, which is greater than the preset time period threshold of 15 days, the count value in this month is set to be valid, and the switch record of the previous month is updated by the count value in this month. . The above timing period and the length of the statistical period, the statistical period including the preset number of the timing period, and the preset counting period threshold value can be performed according to the specific use environment and the control target. For the settings, the above specific values are merely illustrative.
记录更新模块60还可以配置成:将统计周期中的各个统计时间段按照计数值由高到低排序,以得到第一统计时间段序列;将开关记录中的各个统计时间段按照计数值由高到低排序,以得到第二统计时间段序列;对第一统计时间段序列和第二统计时间段序列中排序靠前的多个统计时间段进行匹配,以确定第一统计时间段序列和第二统计时间段序列中排序靠前的统计时间段相同的个数;以及若排序靠前的统计时间段相同的个数超过预设值,将统计周期中的计数值与开关记录中的计数值进行合并处理,以得到新的开关记录,若排序靠前的统计时间段相同的个数小于或等于预设值,将统计周期内的计数值替换开关记录中的计数值,以得到新的开关记录。The record update module 60 may be further configured to: sort each statistical time period in the statistical period according to the count value from high to low to obtain a first statistical time period sequence; and set each statistical time period in the switch record according to the count value. Go to a low ordering to obtain a second statistical time period sequence; match the first statistical time period sequence and the second statistical time period sequence in the second statistical time period sequence to determine the first statistical time period sequence and the first The number of the same statistical time period in the second statistical time period sequence; and if the number of the same statistical time period in the previous ranking exceeds the preset value, the count value in the statistical period and the count value in the switch record Perform a merge process to obtain a new switch record. If the number of the same statistical time period before the sort is less than or equal to the preset value, replace the count value in the statistical period with the count value in the switch record to obtain a new switch. recording.
例如,统计周期为一个月,计时周期为一天,将本月中的各个统计时间段按照计数值由高到低排序,得到第一统计时间段序列如下:08:00至08:20,18:00至18:20,12:00至12:20,18:20至18:40,08:20至08:40,19:00至19:20,12:20至12:40,18:40至19:00,12:40至13:00,20:00至20:20……,将上月开关记录中的各个统计时间段按照计数值由高到低排序,得到第二统计时间段序列如下:08:00至08:20,18:20至18:40,08:20至08:40,20:40至21:00,08:40至09:00,20:00至20:20,18:00至18:20,12:00至12:20,19:00至19:20,12:20至12:40……,由于第一统计时间段序列和第二统计时间段序列中排序靠前的10个统计时间段中相同的个数为8个,超过预设值6个,则认为用户开启密封空间的习惯改变不大,因而可以将本月中的计数值与上月开关记录中的计数值进行合并处理,以得到新的开关记录。具体地,例如本月08:00至08:20时间段的计数值为24,上月开关记录中08:00至08:20时间段的计数值为26,计算(24+26)/2得出25,则可以将08:00至08:20时间段的计数值为25作为新的开关记录。若第一统计时间段序列和第二统计时间段序列中排序靠前的10个统计时间段中相同的个数为3个,小于预设值6个,则可以认为用户开启密封空间的习惯改变较大,可以将本月的计数值替换开关记录中的计数值,以得到新的开关记录。For example, the statistical period is one month, and the counting period is one day. Each statistical time period in the current month is sorted according to the count value from high to low, and the sequence of the first statistical time period is obtained 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..., sorting the statistical time periods in the last month's switch records according to the count value from high to low, and obtaining 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 ordering of the first statistical time period sequence and the second statistical time period sequence The same number of the first 10 statistical time periods is 8 and exceeds the preset value of 6. It is considered that the user's habit of opening the sealed space is not changed much, so the count value in this month can be recorded in the previous month. The count values are combined to obtain a new switch record. Specifically, for example, the count value of the time period from 08:00 to 08:20 in this month is 24, and the count value of the time period from 08:00 to 08:20 in the last month's switch record is 26, and the calculation is (24+26)/2. At 25, the count value of 08:00 to 08:20 can be recorded as a new switch. If the same number of the first 10 statistical time segments in the sequence of the first statistical time period and the second statistical time period is 3, which is less than the preset value of 6, the user can think that the customary change of opening the sealed space is Larger, you can replace the count value in this switch with the count value in the switch record to get a new switch record.
状态检测模块70可以配置成检测冰箱的制氮装置统102的运行状态,并在制氮装置102关闭的情况下获取冰箱的运行时刻。The state detecting module 70 may be configured to detect an operating state of the nitrogen generating apparatus 102 of the refrigerator and acquire an operating time of the refrigerator with the nitrogen generating apparatus 102 turned off.
本实施例中的制氮控制模块30还可以配置成:在运行时刻至时间段的起始点的时间大于第二预设时间阈值的情况下,判断密封空间内的氮气检测 浓度与氮气设定浓度的差值是否大于第一预设浓度值,并在判断结果为是时,控制制氮装置102开启,其中第二预设时间阈值大于第一预设时间阈值;在运行时刻至时间段的起始点的时间小于或等于第二预设时间阈值的情况下,执行判断运行时刻是否位于时间段内或者运行时刻至时间段的起始点的时间是否小于第一预设时间阈值的步骤;在运行时刻至时间段的起始点的时间小于第二预设时间阈值但是大于第一预设时间阈值的情况下,判断氮气检测浓度与氮气设定浓度的差值是否大于第二预设浓度值,并在判断结果为是时,控制制氮装置102开启,其中第二预设浓度值大于第一预设浓度值。The nitrogen production control module 30 in this embodiment may be further configured to: determine the nitrogen detection in the sealed space when the time from the running time to the starting point of the time period is greater than the second preset time threshold. Whether the difference between the concentration and the nitrogen concentration is greater than the first preset concentration value, and when the determination result is yes, controlling the nitrogen generator 102 to be turned on, wherein the second preset time threshold is greater than the first preset time threshold; If the time from the time point to the start time of the time period is less than or equal to the second preset time threshold, whether the time for determining whether the running time is within the time period or the running time to the starting point of the time period is less than the first preset time threshold is performed. The step of determining whether the difference between the nitrogen detection concentration and the nitrogen set concentration is greater than the second pre-preparation when the time from the running time to the start point of the time period is less than the second preset time threshold but greater than the first preset time threshold The concentration value is set, and when the determination result is YES, the nitrogen generator 102 is controlled to be turned on, wherein the second preset concentration value is greater than the first preset concentration value.
例如统计周期为一个月,计时周期为一天时,密封空间开启次数超过预设阈值的时间段为每天的12:00至12:20,若冰箱的运行时刻为09:00,由于运行时刻09:00至时间段的起始点12:00的时间为3小时,大于第二预设时间阈值2小时,判断密封空间内的氮气检测浓度85%与氮气设定浓度90%的差值ΔV为5%,大于第一预设浓度值3%,因而要控制制氮装置102开启,由于运行时刻远早于用户频繁开启密封空间的时间段,因而对密封空间内的氮气浓度要求严格,只要密封空间内的氮气检测浓度与氮气设定浓度的差值ΔV大于第一预设浓度值,就认为密封空间内的氮气浓度需要升高,需要控制制氮装置102开启,以及时升高密封空间内的氮气浓度,避免因氮气浓度过低而影响储物效果。For example, if the statistical period is one month and the time period is one day, the time period in which the sealed space is opened more than the preset threshold is 12:00 to 12:20 every day, if the running time of the refrigerator is 09:00, due to the running time 09: 00 to the starting point of the time period 12:00 is 3 hours, greater than the second preset time threshold of 2 hours, and the difference ΔV between the nitrogen detection concentration 85% in the sealed space and the nitrogen set concentration 90% is 5%. , which is greater than the first preset concentration value of 3%, so that the nitrogen generator 102 is controlled to be turned on. Since the operation time is much earlier than the time period during which the user frequently opens the sealed space, the nitrogen concentration in the sealed space is strictly required, as long as the sealed space is The difference ΔV between the nitrogen detection concentration and the nitrogen concentration is greater than the first preset concentration value, and it is considered that the nitrogen concentration in the sealed space needs to be increased, and it is necessary to control the nitrogen generator 102 to open, and simultaneously raise the nitrogen in the sealed space. Concentration, to avoid the effect of storage due to low nitrogen concentration.
若冰箱的运行时刻为11:30,由于运行时刻11:30至时间段的起始点12:00的时间为30分钟,小于第二预设时间阈值2小时,于是判断运行时刻11:30至时间段的起始点12:00的时间为30分钟,小于第一预设时间阈值1小时,因而认为用户即将开启密封空间,为避免制氮装置102制氮后的氮气流失,要禁止冰箱的制氮装置102开启。If the running time of the refrigerator is 11:30, the time from the running time 11:30 to the starting point of the time period 12:00 is 30 minutes, and the second preset time threshold is less than 2 hours, so that the running time is 11:30 to the time. 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 sealed space. To avoid nitrogen loss after nitrogen production by the nitrogen generator 102, the nitrogen production of the refrigerator should be prohibited. Device 102 is turned on.
若冰箱的运行时刻为10:30,由于运行时刻10:30至时间段的起始点12:00的时间为1.5小时,小于第二预设时间阈值2小时但是大于第一预设时间阈值1小时,判断密封空间内的氮气检测浓度84%与氮气设定浓度90%的差值ΔV为6%,大于第二预设浓度值5%,因而要控制制氮装置102开启,由于运行时刻距离用户频繁开启密封空间的时间段较近,因而对密封空间内的氮气浓度要求较宽松,密封空间内的氮气检测浓度与氮气设定浓度的差值ΔV大于第二预设浓度值时,才认为密封空间内的氮气浓度需要升高,制氮装置102需要开启。 If the running time of the refrigerator is 10:30, the time from the running time of 10:30 to the starting point of the time period of 12:00 is 1.5 hours, less than the second preset time threshold of 2 hours but greater than the first preset time threshold of 1 hour. , judging that the difference ΔV between the nitrogen detection concentration 84% and the nitrogen concentration concentration in the sealed space is 6%, which is greater than 5% of the second preset concentration value, so that the nitrogen generator 102 is controlled to be turned on, because the operation time is away from the user. The time period for frequently opening the sealed space is relatively close, so that the nitrogen concentration in the sealed space is relatively loose, and the difference ΔV between the nitrogen detection concentration and the nitrogen set concentration in the sealed space is greater than the second preset concentration value, and the seal is considered to be sealed. The concentration of nitrogen in the space needs to be increased, and the nitrogen generator 102 needs to be turned on.
需要注意的是,以上所有数值仅为例举并非对本发明的具体限定。It is to be noted that all the above numerical values are merely illustrative and are not intended to limit the invention.

The nitrogen control method of the refrigerator is more intelligent and reasonable, and improves the user experience.
进一步地,本实施例的冰箱制氮的控制装置100,将计时周期划分为多个统计时间段,并为每个统计时间段设置对应的计数器;检测密封空间的开关事件,以根据开关事件发生的时刻在对应的计数器内进行计数,在经过预设的统计周期后,按照每个统计时间段的计数器的计数值更新密封空间的开关记录,可以使密封空间的开关记录更加精确,更能够反映用户的使用习惯,从而使得冰箱的制氮控制方法更加科学,更准确地控制制氮装置的开启时间,以避免密封空间内的氮气流失,进一步提升用户的使用体验。Further, the control device 100 for nitrogen production of the refrigerator of the present embodiment divides the counting period into a plurality of statistical time periods, and sets a corresponding counter for each statistical time period; detects a switching event of the sealed space to generate according to the switching event. The time is counted in the corresponding counter. After the preset statistical period, the switch record of the sealed space is updated according to the counter value of the counter of each statistical time period, so that the switch record of the sealed space can be more accurate and more reflective. The user's usage habits make the nitrogen control method of the refrigerator more scientific, more accurately control the opening time of the nitrogen generating device, to avoid the loss of nitrogen in the sealed space, and further improve the user experience.
图4是根据本发明一个实施例的冰箱的制氮控制方法的示意图,该冰箱的制氮控制方法可以利用上述任一实施例的冰箱的制氮控制装置100执行。如图所示,该冰箱的制氮控制方法依次执行以下步骤:4 is a schematic diagram of a nitrogen control method of a refrigerator according to an embodiment of the present invention, and the nitrogen control method of the refrigerator can be performed by the nitrogen control device 100 of the refrigerator of any of the above embodiments.

以下对一个具体实例进行介绍:The following describes a specific example:
首先获取密封空间开启次数超过预设阈值的时间段为每天的08:00至 08:20,12:00至12:20,18:00至18:20三个时间段,然后对冰箱制氮装置102的运行状态进行检测,若制氮装置102关闭,获取冰箱的运行时刻为17:20,因此以时间段18:00至18:20作为参考,因为运行时刻17:20至时间段起始点18:00的时间为40分钟,小于第二预设时间阈值2小时,继续判断运行时刻17:20至时间段起始点18:00的时间为40分钟,小于第一预设时间阈值1小时,可以判断用户即将开启密封空间,因此禁止制氮装置102启动直至时间段结束点18:20。这样可以有效避免在用户频繁开启密封空间的时间段或临近该时间段时制氮,以造成氮气泄漏,增加冰箱能耗的问题。需要说明的是,以上具体数值仅为例举,并非对本发明的限定。First, the time period from when the sealed space is opened more than the preset threshold is 08:00 every day. 08:20, 12:00 to 12:20, 18:00 to 18:20, and then the operating state of the refrigerator nitrogen generator 102 is detected. If the nitrogen generator 102 is closed, the operating time of the refrigerator is obtained. 17:20, so the time period is 18:00 to 18:20 as a reference, because the running time is 17:20 to the starting time of the time period 18:00 is 40 minutes, less than the second preset time threshold 2 hours, continue to judge The time from the running time 17:20 to the starting point of the time period of 18:00 is 40 minutes, and less than the first preset time threshold value of 1 hour, it can be judged that the user is about to open the sealed space, so the nitrogen generating device 102 is prohibited from starting until the end of the time period 18 :20. This can effectively avoid nitrogen production when the user frequently opens the sealed space or near the time period, thereby causing nitrogen leakage and increasing the energy consumption of the refrigerator. It should be noted that the above specific values are merely examples and are not intended to limit the invention.
