根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

图2是图1所示的冰箱的一种控制框图；
图3是图1所示的冰箱的另一种控制框图；
图4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；以及
图5是根据本发明一个实施例的冰箱的使用容积检测装置的示意图。
图1是根据本发明一个实施例的冰箱的使用容积检测方法所示用冰箱的示意图；该冰箱一般性地可包括：箱体和一个检测组件100。
在本实施例的冰箱中，箱体限定有储物间室400，并且箱体包括有水平设置的顶壁、底壁、以及竖直设置的侧壁。一般而言，竖直设置的侧壁包括三个竖直的侧壁，分别作为左侧壁、右侧壁以及后壁，左侧壁和右侧壁平行设置，后壁与左侧壁和右侧壁均垂直设置，冰箱的门体与后壁相对设置。
检测组件100可选择性地布置于储物间室顶壁或者储物间室侧壁的一个侧面上。
例如检测组件可以布置于后壁上。如果冰箱储物间室内设置有可抽拉的抽屉，检测组件可以布置于抽屉的后板上。本实施例的冰箱要求储物间室的
容积小于或等于预设阈值，一般要求储物间室的可用容量不超过30L。根据测试结果，如果超出这一阈值，有可能导致较大的检测偏差。
图2和图3分别是图1所示的冰箱的两种控制框图。在图2所示的实施例中，检测组件100检测的可见光来自于设置检测组件的可见光源110。该方式主要适用于冰箱储物间室内的照明光源无法满足检测要求的情况。在图3所示的实施例中。在照明光源500满足容积检测要求，可以使用原本的照明光源发出可见光。检测组件100至少还包括：红外光源120、光感器件130。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。
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，从而实现了利用光学原理实现冰箱容积的检测。
冰箱还可包括容积计算装置200，其与检测组件100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。
以上容积计算装置200可以与检测组件100与集成设置，也可以布置于冰箱的主控板上通过线缆与检测组件电连接，以传输检测信号。
本实例的冰箱还可以包括：控制装置300。该控制装置300可以对检测组件100和容积计算装置200进行控制，也可以根据计算出的使用容积对冰箱的制冷进行智能控制。例如控制装置300可以与容积计算装置200以及检测组件100分别连接，并配置成：获取容积检测触发信号，并控制容积计算装置200以及检测组件100开启。该触发信号可以是冰箱关门信号、定时信号等。由于一般打开冰箱门后会对食物进行取放，因此控制装置300可以在每次关门后触发一次容积检测。
另外，控制装置300还配置成：获取容积计算装置200计算得出的使用容积；并且根据使用容积调整冰箱的制冷状态和/或向用户输出使用容积。例如在获取到冰箱的关门信号后，启动冰箱储物间室400内的容积检测装置，以检测储物间室400的使用容积；比较检测出的使用容积和冰箱关门前
的使用容积；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400的冷源以大功率运行，以使冰箱进入速冷模式。以使刚放入的食物温度迅速下降。进入速冷模式的时间可以根据容积变化的大小确定。控制装置300还可以通过无线方式向用户终端输出使用容积，并在使用容积小于预设容积阈值时，向冰箱用户输出食物补充提示信号。
本实施例的冰箱的使用容积检测方法可以由容积计算装置200执行，以对储物间室的使用容积进行计算。图4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S402，利用布置于冰箱的储物间室内部的单个检测组件检测储物间室内的可见光强度和红外光强度；
步骤S404，根据可见光强度对储物间室的使用容积进行估算，得到使用容积的估算值；以及
步骤S406，根据红外光强度计算使用容积的修正因子；累加估算值和修正因子得到使用容积的计算值。
其中步骤S404根据可见光强度对储物间室的使用容积进行估算，得到使用容积的估算值的一种计算方式为
按照公式1对使用容积进行估算：
公式1：V’＝SA×k，在公式1中，V’为使用容积的估算值，SA为检测组件检测到的可见光强度值，k为检测组件的可见光估算系数。
步骤S406根据红外光强度计算使用容积的修正因子的步骤可以包括：按照公式2计算使用容积的修正因子：
公式2：M＝SP×J×T/SA，
在公式2中，M为修正因子，SP为检测组件检测到的红外光强度值，J为检测组件的红外光修正常数，T为检测组件检测得到的红外光强度对应的距离值。
最后使用容积的计算值V＝V’+M＝SA×k+SP×J×T/SA。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，储物间室的可用容积和检测组件的位置均对k和J产生影响，冰箱容积和检测组件的位置确定后，k和J的数值也是确定的。
在步骤S102之前还可以包括：获取容积检测触发信号，容积检测触发信号包括以下任意一项或多项：定时信号、冰箱的关门信号、用户操作的触
发信号。从而在不同情况下开始容积检测。另外在得到使用容积的计算值之后还包括：根据使用容积的计算值调整冰箱的制冷状态和/或向用户输出计算值。例如在获取到冰箱的关门信号后，启动冰箱储物间室400内的容积检测装置，以检测储物间室400的使用容积；比较检测出的使用容积和冰箱关门前的使用容积；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400的冷源以大功率运行，以使冰箱进入速冷模式。以使刚放入的食物温度迅速下降。进入速冷模式的时间可以根据容积变化的大小确定。控制装置300还可以通过无线方式向用户终端输出使用容积，并在使用容积小于预设容积阈值时，向冰箱用户输出食物补充提示信号。
