Description

冰箱 技术领域
本发明涉及冰箱控制领域，特别是涉及一种冰箱。
背景技术
冰箱的智能化是冰箱发展的一个方向，也是众多冰箱厂家开发研究的重点。随着生活水平的提高，人们对电冰箱要求不仅仅停留在基本食品储藏保鲜功能这层面要求，对于能方便人们生活，提高生活质量等智能化操作要求也越来越高。
作为储藏食物的家用电器，用户需要了解冰箱内部空间的使用情况，以确定食物的存放量。在现有技术中，人们一般通过打开冰箱门进行观察的方式，估算冰箱的使用容积。这就需要用户在冰箱附近进行操作，而且经常开关冰箱门会给食物的储存带来不利的影响，这给用户的使用带来了极大的不便。
基于以上问题，现有技术中也出现了利用重量传感器测量冰箱内物体重量、检测特定储物位存放状态、布置摄像头等多种技术手段，用于获取冰箱空间的使用情况，然而这些方案中有些检测结果不准确，有些仅能对特殊的食物进行检测，不能精确地反映冰箱容积的实际使用情况。
发明内容
本发明的一个目的是要提供一种依靠光学感测实现冰箱容积检测的冰箱。
特别地，本发明提供了一种冰箱。该冰箱包括：箱体，限定有储物间室，储物间室的容积小于或等于预设阈值；一个检测组件，布置于储物间室内，其至少包括：光感器件，配置成检测检测组件所在位置的可见光强度和红外光强度；以及容积计算装置，与检测组件连接，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的使用容积。
可选地，箱体包括水平设置的顶壁、底壁、以及竖直设置的侧壁，其中检测组件选择性地布置于顶壁或者侧壁的一个侧面上。
可选地，侧壁包括与冰箱的门体相对设置的后壁，检测组件布置于后壁上。
可选地，以上冰箱还包括：可抽拉地设置于储物间室内的抽屉，检测组件布置于抽屉的后板上。
可选地，检测组件上还设置有红外光源，红外光源配置成向储物间室内发出红外光，以供光感器件检测红外光经反射后的红外光强度。
可选地，检测组件上还设置有可见光源，可见光源配置成向储物间室内发出可见光，以供光感器件检测可见光经反射后的可见光强度。
可选地，以上冰箱还包括照明光源，布置于储物间室内，配置成向储物间室内提供可见光。
可选地，以上冰箱还包括控制装置，与容积计算装置以及检测组件分别连接，并配置成：获取容积计算触发信号，并控制容积计算装置以及检测组件开启。
可选地，控制装置还配置成：获取容积计算装置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。
可选地，容积计算装置布置于检测组件上或者与控制装置一起布置于冰箱的主控板上。
本发明的冰箱在可用容积小于或等于预设阈值的储物间室内布置一个检测组件，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。
进一步地，本发明的冰箱能够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。
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。
附图说明
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1是根据本发明一个实施例的冰箱的结构示意性图；
图2是根据本发明一个实施例的冰箱的控制框图；以及
图3是根据本发明另一实施例的冰箱的控制框图。
具体实施方式
图1是根据本发明一个实施例的冰箱的结构示意性图。该冰箱一般性地可包括：箱体，一个检测组件100以及容积计算装置200。
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100可以布置于后壁上。如果冰箱储物间室400内设置有可抽拉地设置于储物间室内的抽屉，检测组件100可以布置于抽屉的后板上。本实施例的冰箱要求储物间室400的容积小于或等于预设阈值，一般要求储物间室400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分别是根据本发明两个实施例的冰箱的控制框图。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，而不必在检测组件上布置可见光源。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，从而利用光学原理实现冰箱容积的检测。
容积计算装置200，与检测组件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。
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。
容积计算装置200的一种可选检测算法为：按照公式1对使用容积进行估算：
公式1：V’＝SA×k+SP×J×T/SA，在公式1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，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。
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：获取容积计算触发信号，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。
本实施例的冰箱在可用容积小于或等于预设阈值的储物间室内布置一个检测组件，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。
进一步地，本发明的冰箱能够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。
