提示装置650，配置成判断使用容积是否小于预设容积阈值，若是，向冰箱用户输出食物补充提示信号。提示信号可以通过冰箱本地的显示屏进行显示，或者通过点亮预置的提示灯来提醒用户，一种更优的提示方法为通过无线网络向与该冰箱预先绑定的移动终端(例如手机)发送提示信息来进行提醒。
图2和图3分别是根据本发明一个实施例的冰箱中容积检测装置620的两种示意性结构框图，在图2中，容积检测装置620包括至少一个检测组件100和容积计算装置200，至少一个检测组件100和容积计算装置200。其中检测组件100布置于冰箱的储物间室400内，用于发出光信号以及检测光信号。这些光信号包括可见光和红外光。具体地，每个检测组件100至少包括：可见光源110、红外光源120、光感器件130。可见光源110配置成向储物间室400内部发出可见光。红外光源120配置成向储物间室400内部发出红外光。光感器件130配置成检测检测组件100所在位置的可见光强度和红外光强度。检测组件100的数量可以根据储物间室400的体积以及结构进行确定。经过发明人的大量测试，得出以下结论：对于小于等于30L的储物间室400，可以利用一个检测组件100。对于大于30L以及具有分层结构的储物间室400，需要布置多个检测组件100。
随着储物间室400的使用容积的使用大小的改变，可见光和红外光在储物间室400内的反射和遮挡的情况发生变化，并且可见光和红外光的传播特性也存在区别，经过发明人的总结和测试，总结出可见光强度和红外光强度随使用容积的变化而变化的规律，从而利用光学原理实现冰箱容积的检测。
容积计算装置200，与至少一个检测组件100分别电连接，并配置成：获取可见光强度和红外光强度，并根据可见光强度和红外光强度计算储物间 室400的使用容积。
图3所示的实施例与图2相比唯一的区别在于使用储物间室400的照明光源500代替了可见光源110，从而利用原有的光源作为检测用的可见光。该照明光源500除了为用户提供照明之外还可以作为容积计算中所需的可见光的光源。因此，照明光源500的亮度需要达到容积检测的要求。
图4和图5分别示出在冰箱储物间室400内布置多个检测组件100和一个检测组件100的示意图，其中，在检测组件100为多个时，多个检测组件100分布于储物间室400的周壁内侧，并且要求置于周壁同一平面上的任意两个检测组件100的中心点的连线与周壁中与平面相交的其他平面的夹角均不为0度或90度；布置于周壁不同平面上的任意两个检测组件100的中心点的连线与水平面或竖直平面的夹角均不为0度或90度。
根据以上要求，如果多个检测组件100中的至少两个布置于顶壁或者底壁上，则布置于顶壁或者底壁上的检测组件100中任意两个的中心点的连线与侧壁所在的竖直平面的夹角均不为0度或90度。如果多个检测组件100中的至少两个布置于侧壁上，则布置于侧壁上的检测组件100在竖直方向间隔设置。若储物间室400内还设置有与顶壁平行设置的搁物架，将储物间室400分割为多个储物间隔，那么每个储物间隔内需要布置有一个检测组件100。
图4示出了三个检测组件100分别布置于侧壁中的三个侧面上进行容积检测的实例。根据三个检测组件100在竖直方向位置关系，分别称之为第一检测组件101、第二检测组件102、第三检测组件103。
图4所示的结构进行使用容积检测一种具体算法为：
对检测目标的储物间隔的已用容积进行计算包括：按照公式1对检测目标的储物间隔已用容积大小进行估算：
公式1：Vn’＝SnA×kn，
在公式1中，n为检测目标储物间隔内检测组件100的序号，Vn’为第n个检测组件100对应的估算值，SnA为第n个检测组件100检测到的可见光强度值，kn为第n个检测组件100的可见光估算系数；
按照公式2对估算出的Vn’进行修正计算：
公式2：Vn＝Vn’+∑Smp×Mmn；
在公式2中，m为与检测目标的储物间隔内检测组件100在竖直方向上相邻的检测组件100的序号，m取值为n-1和/或n+1，SmA为第m个检测 组件100检测得到的可见光强度，Mmn为第m个检测组件100对第n个检测组件100的计算修正因子，其按照公式3计算得出：
公式3：Mmn＝(Smp×Jmn)/(SmA×Tmn)，
在公式3中，Smp为第m个检测组件100检测得到的红外光强度，Jmn为第m个检测组件100检测对第n个检测组件100的红外光修正常数，Tmn为第m个检测组件100检测得到的红外光强度对应的距离值。kn和Jmn为预先保存于冰箱的常数，通过预先的试验统计得出。
对于第一检测组件101，其在竖直方向上相邻的检测组件100为第二检测组件102，其容积为：
V1＝S1A×k1+S2A×((S2P×J21)/(S2A×T21))。
对于第二检测组件102，其在竖直方向上相邻的检测组件100为第一检测组件101和第三检测组件103，其容积为：
V2＝S2A×k2+S1A×((S1P×J12)/(S1A×T12))+S3A×((S3P×J32)/(S3A×T32))。
对于第三检测组件103，其在竖直方向上的相邻检测组件100为第二检测组件102，其容积为：
V3＝S3A×k3+S2A×((S2P×J23)/(S3A×T23))。
如果需要第一检测组件101、第二检测组件102、第三检测组件103所在储物间隔各自的使用容积就可以直接使用V1、V2、V3。如果需要检测储物间室400的总使用容积就可以将V1、V2、V3累加得出。
以上检测原理为，可见光可以穿过玻璃等间隔，在整个储物间室400内照射，而一般红外光不能穿过玻璃等间隔。
在储物间室400的可用容积较小，例如小于30L时可以仅布置一个检测组件100。其检测算法为：
按照公式4对使用容积进行估算：
公式4：V’＝SA×k+SP×J×T/SA，在公式4中，V’为使用容积的估算值，SA为检测组件100检测到的可见光强度值，k为检测组件100的可见光估算系数，SP为检测组件100检测到的红外光强度值，J为检测组件100的红外光修正常数，T为检测组件100检测得到的红外光强度对应的距离值。k和J为预先保存于冰箱的常数，通过预先的试验统计得出。
以上容积计算装置200可以与检测组件100中的一个集成设置，也可以布置于冰箱的主控板上。
本发明的实施例还提供了一种冰箱的控制方法。图6是根据本发明一个实施例的冰箱的使用容积检测方法的示意图，该方法包括：
步骤S702，在获取到冰箱的关门信号后，启动冰箱储物间室内的容积检测装置，以检测储物间室的使用容积；
步骤S704，比较检测出的使用容积和冰箱关门前的使用容积；
步骤S706，若检测出的使用容积大于关门前的使用容积，则驱动储物间室的冷源以大功率运行，以使冰箱进入速冷模式。
如果在冰箱关门后确定出使用容积增加，可以确定用户放入常温的食物，此时是冰箱进入速冷模式可以避免新放入的食物对已存食物的影响，同时达到节能的效果。
本实施例的使用容积检测方法还可以自动根据增加的使用容积确定运行于速冷模式的定时时间，例如在冰箱进入速冷模式之后包括：计算在关门后增加的使用容积；根据增加的使用容积确定出冰箱运行于速冷模式的定时时间；以及在进入速冷模式的时间达到定时时间时，退出速冷模式。在这种情况下，冰箱中预先保存有新增使用容积范围与定时时间的对应关系表；根据增加的使用容积确定出冰箱运行于速冷模式的定时时间包括：在对应关系表中查询得出增加的使用容积对应的定时时间。该对应关系表可以通过预先的大量试验统计得出，以满足快速将常温的食物制冷的要求。例如在一个具体实例中，可以增加5L以下的速冷时间设置为2分钟，增加5L至10L的速冷时间设置为5分钟，将增加10L以上的速冷时间设置为10分钟。该对应关系表可以根据冰箱的具体规格进行测试后进行设置。
另外，在检测冰箱的储物间室的使用容积之后还包括：保存使用容积的数值，以供后续判断使用。而且还可以判断使用容积是否小于预设容积阈值；若是，向冰箱的用户输出食物补充提示信号。提示信号可以通过冰箱本地的显示屏进行显示，或者通过点亮预置的提示灯来提醒用户，一种更优的提示方法为通过无线网络向与该冰箱预先绑定的移动终端(例如手机)发送提示信息来进行提醒。
步骤S702检测冰箱的储物间室的使用容积可以采用光容积检测的方式先实现，例如使容积检测装置中的至少一个检测组件中的光感器件启动，以检测检测组件各自所在位置的可见光强度和红外光强度；根据可见光强度和红外光强度计算储物间室的使用的容积。具体的检测算法在对本实施例的冰 箱中已有介绍，在此不做赘述。
本实施例的冰箱与冰箱的使用容积检测方法，在储物间室内布置检测组件，利用光学原理对冰箱储物间室已使用的容积进行检测，检测结果精确，无需开启冰箱门体，提高了用户的使用体验并保持了食物良好的储藏环境。而且还可以利用检测出的冰箱容积实现把冰箱的智能控制，提高了冰箱的智能化程度。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
