本文中“被配置为”的使用意味着开放和包容性的语言，其不排除适用于或被配置为执行额外任务或步骤的设备。
本公开一些实施例提供一种冰箱100。如图1所示，冰箱100包括标签检测装置30、箱门开关检测装置40、控制器50、压缩机61、冷凝器62和蒸发器63。控制器50与第一标签检测装置30、箱门开关检测装置40、压缩机61、冷凝器62和蒸发器63耦接，第一标签检测装置30、箱门开关检测装置40、压缩机61、冷凝器62和蒸发器63在控制器50 的控制下工作。
下面主要对冰箱100的制冷工作原理进行示例性说明。
冰箱100的制冷过程包括压缩过程、冷凝过程、节流过程和蒸发过程。其中，压缩过程为：压缩机61将低温、低压的制冷剂吸入，并将该制冷剂压缩成高温、高压的过热气体，再驱动该过热气体进入冷凝器62中。冷凝过程为：冷凝器62将高温、高压的制冷剂气体冷却为常温、高压的饱和蒸气后，进一步冷却该饱和蒸汽，得到制冷剂的饱和液体。节流过程为：制冷剂的饱和液体经干燥过滤器滤除水分和杂质后流入毛细管，在该毛细管中进行节流降压后，变为常温、低压的湿蒸气进入蒸发器63中。蒸发过程为：蒸发器63将该常温、低压的湿蒸气汽化为低温、低压的干饱和蒸汽，从而吸收蒸发器63周围的热量，达到降低冰箱100内部的温度的效果。此外，蒸发器63还可以将汽化后的制冷剂再次输入压缩机61中，以循环利用制冷剂。
下面主要结合附图，对冰箱100利用电子标签进行食材管理的过程进行示例性说明。
如图2所示，本公开一些实施例提供的冰箱100包括箱体10和箱门20。箱门20设置在箱体10上。
标签检测装置30被配置为检测冰箱中的电子标签。电子标签被配置为存储与食材有关的信息。箱门开关检测装置40被配置为检测箱门20的开启和关闭。
控制器50与标签检测装置30和箱门开关检测装置40耦接，且被配置为：
响应于来自箱门开关检测装置40的关门信号，通过标签检测装置30获取冰箱100中的所有电子标签的信息，以得到第一标签信息集合；
将第一标签信息集合与第二标签信息集合进行比较；第二标签信息集合为响应于上述关门信号的上一次关门信号、通过标签检测装置30获取的冰箱100中的所有电子标签的信息；
若第二标签信息集合包括第一标签信息集合中不存在的第一电子标签，则根据上述关门信号的接收时刻，更新与第一电子标签关联的第一食材的取出时刻；
若第一标签信息集合包括第二标签信息集合中不存在的第二电子标签，则根据上述关门信号的接收时刻，更新与第二电子标签关联的第二食材的放入时刻，并根据该第二食材的放入时刻更新该第二食材的保质期。
用户在使用冰箱时，可能出现将冰箱中的食材取出后再放回冰箱的情况，且食材从冰箱中取出后，该食材的储存温度通常会上升，从而引起该食材的保质期缩短。本公开一些实施例提供的冰箱100，能够在箱门开关检测装置40检测到箱门20关闭时，通过标签检测装置30获取的冰箱100中的所有电子标签的信息，以得到第一标签信息集合。然后将该第一标签信息集合与箱门20上一次关闭时获取到的第二标签信息集合进行比较，若第一标签信息集合包括第二标签信息集合中不存在的第二电子标签，说明该第二电子标签为用户在本次关门前放入冰箱100的新增标签。此时，可以根据来自箱门开关检测装置40的关门信号的接收时刻，更新与该第二电子标签关联的第二食材的放入时刻，并根据该第二食材的放入时刻更新该第二食材的保质期。因此，本公开一些实施例提供的冰箱100能够动态更新放入该冰箱100中的食材的保质期，从而提高利用冰箱100监控食材是否过期的准确性，进而提升用户体验。
需要说明的是，上述电子标签可以为采用近场通信(NearFieldCommunication，NFC)技术的标签，也可以为采用射频识别(RadioFrequencyIdentification，RFID)技术的标签。 当电子标签为采用NFC技术的标签时，标签检测装置30例如可以为NFC天线；当电子标签为采用RFID技术的标签时，标签检测装置30例如可以为RFID天线。
示例性地，一个电子标签关联一种食材。当用户在冰箱100中放入或取出食材时，可以将该食材和与该食材关联的电子标签一同放入或取出。示例性地，电子标签的信息可以包括该电子标签的识别码。不同电子标签具有不同的识别码，以使控制器50区分多个电子标签。电子标签的识别码在出厂前写入到电子标签的芯片内。
在一些示例中，电子标签的识别码和与该电子标签关联的食材的信息(例如，食材名称、食材图标等)，可以是预先对应存储在食材数据库中的。从而，控制器50可以在通过标签识别器30获取到电子标签的信息后，根据该电子标签的信息从食材数据库中查询得到与该电子标签关联的食材的信息。在另一些示例中，用户在将电子标签放入冰箱100中时，可以手动编辑与该电子标签关联的食材的信息。在用户完成编辑后，冰箱100可以将电子标签的信息和与该电子标签关联的食材的信息对应存储。
示例性地，不同电子标签的表面可以设置有不同的标记(例如，与不同种类的食材对应的颜色、图案等)，以便于用户识别和区分。电子标签例如可以为卡片。电子标签可以夹在食材上，也可贴在食材的包装袋或包装盒上。
在一些示例中，标签检测装置30设置在箱体10或箱门20上。该标签检测装置30的检测范围覆盖整个冰箱100，以检测该冰箱100中的所有电子标签。
当控制器50接收到来自箱门开关检测装置40的关门信号时，说明用户可能进行了食材的放入和/或取出。此时，控制器50控制标签检测装置30对冰箱100中的所有电子标签进行检测，以得到本次关门时的第一标签信息集合并进行记录。然后，将该第一标签信息集合与上一次接收到关门信号时得到的第二标签信息集合进行比较，以确定用户是否进行了食材的放入或取出。
在一些示例中，第二标签信息集合包括第一标签信息集合中不存在的第一电子标签。这说明用户在本次关闭箱门20之前从冰箱100中取出了该第一电子标签和与该第一电子标签关联的第一食材。这时，控制器50可以根据本次的关门信号的接收时刻，更新该第一食材的取出时刻。
在另一些示例中，第一标签信息集合包括第二标签信息集合中不存在的第二电子标签。这说明用户在本次关闭箱门20之前将该第二电子标签和与该第二电子标签关联的第二食材。这时，控制器50根据本次的关门信号的接收时刻，更新该第二食材的放入时刻，并根据该第二食材的放入时刻更新该第二食材的保质期。
需要说明的是，在第二标签信息集合包括第一标签信息集合中不存在的第一电子标签的情况下，第一标签信息集合也可以包括第二标签信息集合中不存在的第二电子标签。这说明用户在本次关闭箱门20之前取出了第一食材，且放入了第二食材。此时，控制器50可以分别更新第一食材的取出时刻、第二食材的放入时刻和第二食材的保质期。
示例性地，当控制器50得到本次关闭箱门20时的第一标签信息集合并进行记录后，可以将除第一标签信息集合和上一次关闭箱门20时得到的第二标签信息集合以外的历史标签信息集合删除，以防止占用过多内存。
另外，在控制器50更新完第二食材的保质期后，控制器50可以将该第二食材的保质期和第二电子标签对应存储至上述食材数据库中，且该食材保质期的期限在更新完后会随着时间流逝而缩短。或者，控制器50可以将该第二食材的保质期写入第二电子标签中。
在一些示例中，可以将关门信号的接收时刻作为第一食材的取出时刻。但考虑到箱门开关检测装置40的信号处理时间和关门信号的传输时间，第一食材的实际取出时间与关门信号的接收时刻之间会存在一定的误差。因此，在另一些示例中，可以根据关门信号的接收时刻、预设的信号处理时间和预设的传输时间得到第一食材的取出时刻，以提高该取出时刻的准确性，进而提高后续更新该第一食材的保质期时的准确性。例如，可以用关门信号的接收时刻减去预设的信号处理时间和预设的传输时间，得到第一食材的取出时刻。
需要说明的是，第二食材的放入时刻的更新方式可以参考前述实施例中第一食材的取出时刻的更新方式，在此不再赘述。
在一些实施例中，冰箱100还包括标签盒。该标签盒被配置为存储未使用的空闲电子标签。该标签盒内设置有标签读写装置。该标签读写装置被配置为检测标签盒中存储的空闲电子标签。
在一些示例中，标签读写装置可以将空闲电子标签的信息发送给控制器50，以使控制器50可以根据空闲电子标签的信息，将该空闲电子标签中存储的食材的信息、食材取出时刻和食材放入时刻等信息删除。这样，用户在使用完电子标签后，可以将该电子标签放回到标签盒中，以将该电子标签的数据初始化，以便下次用于关联其他食材。
下面，主要对控制器50更新第二食材的保质期的方式进行示例性说明。
在一些实施例中，控制器50被配置为：
在第二食材的取出时刻为空的情况下，获取该第二食材所在的区域的第一温度；
获取该第二食材在第一温度下的预计保质期，并根据该第二食材的放入时刻和预计保质期，更新第二食材的保质期。
在一些示例中，控制器50可以在根据上述关门信号的接收时刻，更新与第二电子标签关联的第二食材的放入时刻后，获取该第二食材的取出时刻。通过判断第二食材的取出时刻是否为空，可以确定该第二食材是首次放入冰箱100还是从冰箱100中取出后重新放入。在第二食材的取出时刻为空的情况下，控制器50可以确定该第二食材是首次放入冰箱100。
在不同的存储温度下，食材的保质期的会有较大的不同。在该实施例中，在第二食材首次放入冰箱100中的情况下，可以根据该第二食材所在的区域的第一温度，获取该第二食材的预计保质期，再根据该第二食材的放入时刻和预计保质期更新该第二食材的保质期，从而能够提高该冰箱100记录的该第二食材的保质期的准确性。
在一些示例中，控制器50可以将该第二食材所在的区域的设定温度作为上述第一温度。示例性地，该第二食材所在的区域例如为“冷冻室”、“冷藏室”、“变温室”等间室。该第二食材所在的区域的设定温度可以为冰箱100出厂设置中的默认值，也可以为用户的设定值。在另一些示例中，冰箱100还包括多个温度传感器，该多个温度传感器设置在冰箱100的不同间室中，且被配置为检测该不同间室的温度。在该示例中，控制器50可以获取与第二食材处于同一间室的温度传感器检测到的温度，将该温度作为上述第一温度。
在一些示例中，如表1所示，冰箱100的中预先存储有预计保质期查询表，该预计保质期查询表记录有食材、温度与预计保质期之间的对应关系，以反映各种食材在不同温度下的不同预计保质期。此时，控制器50可以根据第二食材的食材信息(例如，食材名 称)和第一温度，从该预计保质期查询表中查询得到该第二食材的预计保质期。在另一些示例中，可以预先将各种食材在一些温度下的不同预计保质期的对应关系作为训练样本集，训练神经网络模型，以得到保质期预测模型。该保质期预测模型能够预测各种食材在不同温度下的不同预计保质期。此时，控制器50可以将第二食材的食材信息和第一温度输入该保质期预测模型，得到该第二食材的预计保质期。
表1食材、温度与预计保质期之间的对应关系
Figure PCTCN2022122722-appb-000001
在另一些实施例中，继续参照图1，冰箱100还包括：温度检测装置70。温度检测装置70与控制器50耦接，且被配置为检测冰箱100所处的环境温度。
控制器50被配置为：
在满足第一条件的情况下，通过温度检测装置70，获取从第二食材的取出时刻至第二食材的放入时刻这一时间段内的平均环境温度；第一条件包括第二食材的取出时刻不为空；
根据平均环境温度，获取第二食材的第一保质期影响时间；
根据上述第一保质期影响时间，更新该第二食材的保质期。
在该实施例中，在满足第二食材的取出时刻不为空的情况下，控制器50可以确认该第二食材是从冰箱100中取出后再次放入了该冰箱100。由于冰箱100所处的环境温度通常高于该冰箱100的内部温度，而存储温度的改变会引起食材的保质期改变，因此，控制器50通过温度检测装置70获取从该第二食材的取出时刻至该第二食材的放入时刻这一时间段内的平均环境温度，然后利用根据该平均环境温度获取到的第一保质期影响时间更新该第二食材的保质期，能够进一步提高该冰箱100记录的第二食材的保质期的准确性。
在一些示例中，冰箱100中预先存储有第一保质期影响时间查询表，该第一保质期影响时间查询表记录有食材、温度与第一保质期影响时间之间的对应关系，以反映各种食材在不同温度下的不同第一保质期影响时间。此时，控制器50可以根据第二食材的食材信息和上述平均环境温度，从该第一保质期影响时间查询表中查询得到该第二食材的第一保质期影响时间。在另一些示例中，可以预先将各种食材在一些温度下的不同第一保质期影响时间的对应关系作为训练样本集，训练神经网络模型，以得到第一保质期影响时间预测模型。该第一保质期影响时间预测模型能够预测各种食材在不同温度下的不同第一保质期影响时间。此时，控制器50可以将第二食材的食材信息和上述平均环境温度输入该第一保质期影响时间预测模型，得到该第二食材的第一保质期影响时间。
在一些示例中，控制器50可以将该第二食材的更新前的保质期与上述第一保质期影响时间相加，以得到该第二食材更新后的保质期。示例性地，若第二食材放置在冰箱100外的保质期比放置在冰箱100内的保质期短，则上述第一保质期影响时间为负值。或者， 若第二食材放置在冰箱100外的保质期比放置在冰箱100内的保质期长，则上述第一保质期影响时间为正值。
在又一些实施例中，继续参照图1，冰箱100还包括湿度检测装置80。湿度检测装置80与控制器50耦接，且被配置为检测冰箱100所处的环境湿度。
控制器50被配置为：
在满足第一条件的情况下，通过湿度检测装置80，获取从第二食材的取出时刻至第二食材的放入时刻这一时间段内的平均环境湿度；第一条件包括第二食材的取出时刻不为空；
根据平均环境湿度，获取第二食材的第二保质期影响时间；
根据第二保质期影响时间，更新第二食材的保质期。
在该实施例中，在满足第二食材的取出时刻不为空的情况下，控制器50可以确认该第二食材是从冰箱100中取出后再次放入了该冰箱100。由于冰箱100所处的环境湿度通常高于该冰箱100的内部湿度，而存储温度的改变会引起食材的保质期改变，因此，控制器50通过湿度检测装置80获取从该第二食材的取出时刻至该第二食材的放入时刻这一时间段内的平均环境湿度，然后利用根据该平均环境湿度获取到的第二保质期影响时间更新该第二食材的保质期，能够进一步提高该冰箱100记录的第二食材的保质期的准确性。
需要说明的是，关于控制器50获取第二保质期影响时间、以及获取第二食材更新后的保质期的方式，可以参照前述实施例中对控制器50获取第一保质期影响时间、以及获取第二食材更新后的保质期的方式的相关说明，在此不再赘述。
在一些示例中，上述两个实施例中的第一条件还包括从第二食材的取出时刻至第二食材的放入时刻这一时间段大于预设的第一阈值。
由于第二食材短时间取出对该第二食材的保质期的影响较小，因此，该实施例中的冰箱100通过设置限定第一条件包括从第二食材的取出时刻至第二食材的放入时刻这一时间段大于预设的第一阈值，能够避免控制器50对取出时间较短的食材进行保质期更新，从而减少了计算资源的占用，降低了功耗。
在又一些实施例中，控制器50还被配置为：
在第一标签信息集合包括第二标签信息集合中不存在的第二电子标签、且第二食材的取出时刻不为空的情况下，获取第二食材所在的区域的第一温度；
判断第一温度与第二温度之间的差值是否大于预设的第二阈值；第二温度为第二食材在该第二食材的取出时刻之前、所在的区域的温度；
若该差值大于第二阈值，则根据该差值，获取第二食材的第三保质期影响时间；
根据第三保质期影响时间，更新第二食材的保质期。
在冰箱100的使用过程中，用户可能会将食材从A间室拿出，再放回B间室，而A、B间室的温度通常不同，这时，食材的保质期也会发生变化。因此，上述实施例中的冰箱100在第二食材的取出时刻不为空的情况下，可以根据该第二食材当前所在的区域的第一温度，与该第二食材的取出时刻之前、所在的区域的第二温度之间的差值，确定该第二食材的第三保质期影响时间，并根据该第三保质期影响时间更新该第二食材的保质期，从而能够进一步提高该第二食材的保质期的准确性。
在一些示例中，冰箱100中预先存储有第三保质期影响时间查询表，以反映不同的温差对各种食材的保质期的影响时间。此时，控制器50可以根据第一温度与第二温度之间 的差值和第二食材的信息，从该对应关系中查询得到该第二食材的第三保质期影响时间。在另一些示例中，控制器50也可以将第一温度与第二温度之间的差值和第二食材的信息输入训练好的神经网络模型，得到该第二食材的第三保质期影响时间。
需要说明的是，关于神经网络模型的训练方式、控制器50获取第二食材更新后的保质期的方式，可以参照前述实施例的相关内容，在此不再赘述。
下面，通过一个具体示例，对上述食材的保质期更新过程进行举例说明。
如图3所示，在用户将第二食材放入冰箱100中并关门后，箱门开关检测装置40给控制器50发送关门信号。控制器50接收到该关门信号后，通过标签检测装置30获取箱体10内的所有电子标签的信息，得到本次关门时的第一标签信息集合。然后，控制器50获取上一次关门时的第二标签信息集合，通过对第一标签信息集合和第二标签信息集合进行比较，确定第一标签信息集合包括第二标签信息集合中不存在的第二电子标签的信息。此时，控制器50根据关门信号的接收时刻确定与第二电子标签关联的第二食材的取出时刻，并获取该第二食材的取出时刻。
若第二食材的取出时刻为空，则说明该第二食材是首次放入冰箱100，此时控制器50获取第二食材所在的区域的第一温度T1并记录，并将该第二食材的信息输入保质期预测模型，以获取该第二食材在第一温度T1下的预计保质期D，最后更新该第二食材的保质期为D。
若第二食材的取出时刻不为空，则说明该第二食材是取出后又放入冰箱100中，此时控制器获取从第二食材的取出时刻至放入时刻这一时间段t，并通过温度检测装置70和湿度检测装置80获取该时间段t内的平均环境温度和平均环境湿度。然后，控制器50根据该平均环境温度和该平均环境湿度，通过查询获取第二食材的第一保质期影响时间D1和第二保质期影响时间D2。然后，控制器50获取第二食材在取出时刻之前所在的区域的第二温度T2，并判断第一温度T1与第二温度T2之间的差值的绝对值|T1-T2|是否大于第二阈值T0。若是，则说明第一温度T1与第二温度T2之间的温差较大，此时控制器50根据第一温度T1与第二温度T2之间的差值，获取第二食材的第三保质期影响时间D3，最后更新第二食材的保质期为D+D1+D2+D3。若否，则说明该温差较小，此时控制器50更新第二食材的保质期为D+D1+D2。
本公开一些实施例还提供一种冰箱食材保质期的更新方法。如图4所示，该冰箱食材保质期的更新方法包括如下步骤。
S1、响应于来自箱门开关检测装置40的关门信号，通过标签检测装置30获取冰箱100中的所有电子标签的信息，以得到第一标签信息集合。
其中，箱门开关检测装置40被配置为检测箱门20的开启和关闭。标签检测装置30被配置为检测冰箱100中的电子标签。电子标签被配置为存储与食材有关的信息。
S2、将第一标签信息集合与第二标签信息集合进行比较。
其中，第二标签信息集合为响应于上述关门信号的上一次关门信号、通过标签检测装置30获取的冰箱100中的所有电子标签的信息。
S3、若第二标签信息集合包括第一标签信息集合中不存在的第一电子标签，则根据该关门信号的接收时刻，更新与该第一电子标签关联的第一食材的取出时刻。
