在本发明的一些实施例中，每个检测部件可为具有光发射部和光接收部的光传感器。检测部件为3个，处于同一直线上或呈三角形布置。具体地，3个检测部件可分别为第一检测部件21、第二检测部件22和第三检测部件23。预定顺序可为第一检测部件21、第二检测部件22和第三检测部件23依次生成各自的操作信号。在需要开门时，外界操作的施行主体依次处于第一检测部件21、第二检测部件22和第三检测部件23的前方，使第一检测部件21、第二检测部件22和第三检测部件23依次生成各自的操作信号，
控制模块30生成开门指令，以使执行模块40执行开门动作；然而，当外界操作的施行主体依次处于第三检测部件23、第二检测部件22和第一检测部件21的前方，使第三检测部件23、第二检测部件22和第一检测部件21依次生成各自的操作信号，控制模块30判断该顺序不符合上述预定顺序，不生成开门指令，执行模块40不动作。
例如，当用户双手被占用，用手不太方便与冰箱100接触去打开冰箱100门体时；老人年纪过大、气力不足，而冰箱100门又过于笨重时；厨房做饭或者收拾食物时，双手充满油腻，不愿用手接触打开冰箱100门体时，可以用身体部位非接触地打开冰箱100门体。具体地，用户自己的肢体可作为外界操作的施行主体，如，用户可使头部按照所述预定顺序依次阻挡相应的检测部件。用户也可使用手以及手里里携带的物品作为外界操作的施行主体，如，用户的手以及手里的物品可按照所述预定顺序一起移动以依次阻挡相应的检测部件。用户也可使用手里里携带的物品作为外界操作的施行主体，如，用户的手带动手里的物品按照所述预定顺序一起移动以依次阻挡相应的检测部件。每个检测部件可为光传感器时，外界操作的施行主体应具有优良的使光线反射的性能。
为了进一步防止冰箱100误开门，该开门装置的控制模块30还配置成：根据每个检测部件的操作信号计算每个检测部件与外界操作发生位置处之间的距离，且当距离在预定距离之内时，确定相应检测部件生成了有效信号。也就是说，每个检测部件必须在其前方的外界操作的施行主体处于一预定距离内时生成的操作信号为有效的信号，可防止多个检测部件检测离冰箱100较远地方的动作的时间符合预定顺序的情况下造成冰箱100开门，引起不必要的开门操作。在本发明的一些替代性实施例中，如图2所示，开门装置还包括：多个距离传感器50，分别与控制模块30电连接。每个距离传感器50可配置成：在一个检测部件生成操作信号时，检测外界操作发生位置处与该检测部件之间的距离，并将该距离传递给控制模块30，即在一个相应检测部件前方具有外界操作的施行主体时检测外界操作的施行主体与该检测部件之间的距离，并将该距离传递给控制模块30。控制模块30还配置成：在该距离在预定距离之内时，确定相应检测部件生成了有效信号。预定距离优选为10cm至30cm，例如预定距离可为15cm。
为了保证用户等生命体在门体附近才能开启门体，本发明实施例中的开
门装置还包括人体感应模块60，其与控制模块30电连接，配置成在其感应范围内感测到人体时生成人体感应信号。而且控制模块30还配置成：在接收到人体感应模块60的人体感应信号时控制每个检测部件开启，以防止冰箱旁边无人时冰箱意外开启，也可防止当距离传感器失效时，冰箱的意外开启。例如，当冰箱100上部或侧上方的物品掉落时，刚好使多个检测部件检测到前方具有该掉落的物品(即外界操作的施行主体)的时间符合预定顺序，使冰箱100门体打开，此时用户不在旁边，会造成冰箱100内的冷气大量泄漏。人体感应模块60的感应范围半径优选为0.7m至1m，具体可选择0.8m。
图3是根据本发明一个实施例的冰箱100的示意性结构图。本发明实施例还提供了一种冰箱100。冰箱100一般性可包括箱体110和至少一个门体。箱体110内限定有至少一个容纳空间。每个门体安装于箱体110，配置成封闭一个相应容纳空间，每个门体可枢转地或可滑动地安装于箱体110。特别地，该冰箱100还包括一个或多个上述任一实施例中的开门装置，每个开门装置的执行模块40配置成在接收到开门指令后驱动一个门体打开。
具体地，本发明实施例的冰箱100可为对开门冰箱，其箱体110内限定有第一冷藏冷冻空间及第二冷藏冷冻空间。对开门冰箱的门体为两个，分别为第一门体120和第二门体130，两个门体相对设置，分别用以封闭第一冷藏冷冻空间和封闭第二冷藏冷冻空间。对开门冰箱的开门装置为一个，其执行模块40配置成在接收到开门指令后驱动第一门体120打开。该开门装置的多个检测部件包括第一检测部件21、第二检测部件22和第三检测部件23，第一检测部件21、第二检测部件22和第三检测部件23沿竖直方向从上向下依次间隔地安装于第二门体130，且临近第一门体120的开启侧，可防止第一门体120在开启时碰撞到人体。
在本发明的一些进一步的实施例中，第二检测部件22的高度距离该对开门冰箱底端的距离大约为1.5m至1.8m，以便于人的肢体动作，尤其是头部、肩部或背部的动作。每两个相邻的检测部件之间的距离在5mm至50mm之间，每两个相邻的检测部件之间适当的距离可防止两个相邻的检测部件由于之间的距离过短产生信号干扰，也可防止两个相邻的检测部件由于之间的距离过长，使肢体需要进行较长时间的动作。
第一门体120也可为双层门体，其包括内门体和外门体121。内门体的朝向第一冷藏冷冻空间的部分形成有第三冷藏冷冻空间，用以储存小件物
品，例如酒水、饮料等。外门体121可枢接于内门体或箱体110，用以自外侧封闭第三冷藏冷冻空间，以在需要自第三冷藏冷冻空间内取出放置的物品时，使用者无需打开较大的内门体，即可以取出，避免了冷气的过多逸出，节省能源。本发明实施例的开门装置也可用于控制开启第一门体120的外门体121。在本发明的一些替代性实施例中，多个检测部件可沿横向方向从冰箱一侧向冰箱另一侧依次设置在冰箱的下部，以便于使用户的脚作为外界操作的施行主体。
在本发明的一些实施例中，多个检测部件可预组装为一整体式模块，人体感应模块60可与多个检测部件集成设置。人体感应模块60也可单独安装在箱体的上部。人体感应模块60可设置一个感应角度和感应距离，以形成一个扇形的感应区，只要人体进入该感应区，人体感应模块就可以生成人体感应信号，以使多个检测部件启动，从而使当人在冰箱附近时，冰箱才允许其门体在开门装置的控制下打开。
图4是根据本发明一个实施例的非接触式开门方法的示意性流程图。如图4所示，本发明实施例还提供了一种用于冰箱100的非接触式开门方法，该方法可包括：步骤C：接收多个检测部件分别根据其前方的外界操作生成的操作信号。和，步骤E：在每个检测部件生成操作信号的时间符合预定顺序的情况下，生成一开门指令，以使执行模块40执行开门动作。当用户不方便用手开门，且需要打开冰箱100门时，用户可使自己的身体某部分处于检测部件的前方，以使检测部件产生操作信号。具体地，用户可使自己的肢体以按照所述预定顺序依次阻挡相应的检测部件，从而生成开门指令，使执行模块40动作打开冰箱100门体。
具体地，多个检测部件包括第一检测部件21、第二检测部件22和第三检测部件23。预定顺序可为以下任意一种：第一种预定顺序，第一检测部件21、第二检测部件22和第三检测部件23依次生成各自的操作信号；第二种预定顺序，第二检测部件22、第一检测部件21和第三检测部件23依次生成各自的操作信号；第三种预定顺序，第一检测部件21、第二检测部件22和第三检测部件23依次生成各自的操作信号，之后第三检测部件23、第二检测部件22和第一检测部件21又依次生成各自的操作信号。本领域的技术人员也可设置其他预定顺序。
在本发明的一些实施例中，如图5所示，在步骤C之后还包括步骤D，
步骤D包括：根据每个检测部件的操作信号计算每个检测部件与外界操作发生位置处之间的距离，当距离在预定距离之内时，确定相应检测部件生成了有效信号，且在每个检测部件生成的操作信号均有效的情况下进入步骤E。在本发明的一些替代性实施例中，在一个检测部件生成操作信号时，接收距离传感器检测得到的该检测部件与外界操作发生位置处之间的距离，当距离在预定距离之内时，确定相应检测部件生成了有效信号，且在每个检测部件生成的操作信号均有效的情况下进入步骤E。优选地，预定距离为10cm至30cm。
在本发明的一些实施例中，如图5所示，在步骤C之前还包括：步骤A：接收人体感应模块60在其感应范围内感测到人体时生成的人体感应信号；和步骤B：在接收到人体感应模块60的人体感应信号时，控制每个检测部件开启。人体感应模块60的感应范围半径为0.7m至1m。
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。
