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门的控制方法的流程图；
图2是根据本发明另一个实施例的冰箱门的控制方法的流程图；
图3是根据本发明另一个实施例的冰箱门的控制方法的流程图；
图4是根据本发明一个实施例的冰箱的结构示意图。
具体实施方式
图1是根据本发明一个实施例的冰箱门的控制方法的流程图。参见图1，冰箱门的控制方法一般性地可包括以下步骤S102至步骤S106。
步骤S102：获取冰箱门的开闭状态。
步骤S104：启动与开闭状态对应的人感检测功能。
在本步骤中，已知冰箱门的状态为打开状态或者关闭状态。当冰箱门为打开状态时，启动与打开状态对应的人感检测功能，用于检测是否需要关闭冰箱门。当冰箱门为关闭状态时，启动与关闭状态对应的人感检测功能，用于检测是否需要打开冰箱门。
步骤S106：通过人感检测功能检测冰箱预设范围内的人体状态，并根据人体状态控制冰箱门的开闭。预设范围可以根据实际情况进行设定，具体地，例如，预设范围可以为0.5-1.5m之间的任意值，如0.8m、1m等。
在本实施例中，获取冰箱门的开闭状态，启动与开闭状态对应的人感检 测功能，通过人感检测功能检测冰箱预设范围内的人体状态，并根据人体状态控制冰箱门的开闭，实现了对冰箱门的自动开闭，减少了用户的操作，方便了用户的使用，提高了用户的体验。
在本发明一个实施例中，当开闭状态为关闭状态时，步骤S106可包括：
获取人体的实时移动速度；
判断实时移动速度是否处于递减状态；
若是，打开冰箱门。
在本实施例中，当冰箱门的状态为关闭状态时，启动与关闭状态对应的人感检测功能，用于检测是否需要打开冰箱门。具体地，可以判断人体的实时移动速度，若人体的实时移动速度处于递减状态，则可以确定人体即将停止在冰箱的附近，即用户需要使用冰箱，因此，可以打开冰箱门。根据人体的实时移动速度是否处于递减状态来判断是否需要打开冰箱门，具有较高的准确性。另外，在判断实时移动速度是否处于递减状态时，递减状态可以是匀速递减，也可以时非匀速递减。
在本发明一个实施例中，在判断实时移动速度是否处于递减状态的步骤之前，可包括：
判断人体至冰箱的距离是否小于预设距离，预设距离小于预设范围的边界至冰箱的距离；
若是，执行判断实时移动速度是否处于递减状态的步骤。
在本实施例中，由于预设范围相对较大，用户在预设范围内也可能由于其他原因出现移动速度递减的情况，因此，在判断实时移动速度是否处于递减状态的步骤之前，判断人体至冰箱的距离是否小于预设距离，可以有效地排除其他原因导致用户移动速度递减的情况，进一步提高判断是否需要开门的准确性。一般情况下，预设距离和预设范围的边界至冰箱的距离之间的差值可以为20至30厘米。当然，预设距离和预设范围的边界至冰箱的距离之间的差值也可以正比于预设范围的边界至冰箱的距离，即预设范围的边界至冰箱的距离越大，这个差值就可以越大。
在本发明一个实施例中，在人体至冰箱的距离小于预设距离时，可包括：
判断人体移动的方向是否为朝向冰箱的门体的方向；
若是，执行判断实时移动速度是否处于递减状态的步骤。
在本实施例中，可以判断人体至门体的距离是否减少，若人体至门体的 距离减少，则可以确定人体移动的方向包括朝向冰箱的门体的方向。在确定人体移动的方向为朝向冰箱的门体的方向后，执行判断实时移动速度是否处于递减状态的步骤，可以进一步提高判断用户是否需要使用冰箱，进而提高判断是否需要打开冰箱门的准确性。
在本发明一个实施例中，若实时移动速度未处于递减状态，继续维持冰箱门的关闭状态。
在本实施例中，当冰箱的门体处于关闭的状态时，若实时移动速度未处于递减状态，则说明用户并不需要使用冰箱，只是在冰箱附近路过，因此，继续维持冰箱门的关闭状态。
在本发明一个实施例中，在打开冰箱门的步骤之前，可包括：
启动光感检测功能，并检测是否获取到光感检测功能的触发信号；
若是，执行打开冰箱门的步骤。
在本实施例中，光感检测功能的触发信号可包括光线的变化，若光线变暗，则可以说明用户遮挡住了部分光线，即可以确定用户需要使用冰箱。因此，在获取到光感检测功能的触发信号后，打开冰箱门，可以减少误判。
在本发明的一些其他实施例中，当通过人感检测功能检测到冰箱预设范围内的人体状态时，还可包括：显示冰箱的运行状态。
在本实施例中，当通过人感检测功能检测到冰箱预设范围内的人体状态时，考虑到用户可能需要观察冰箱的运行状态，因此，冰箱的运行状态，可以是用户及时了解冰箱的相关信息。运行状态可包括冰箱是否处于杀菌模式、冷藏室的温度以及储藏室的温度等。
在本发明一个实施例中，当开闭状态为打开状态时，步骤106可包括：
计算预设范围内无人状态的持续时间；
判断持续时间是否大于或等于预设时间；
若是，关闭冰箱门。
在本实施例中，当开闭状态为打开状态时，启动与打开状态对应的人感检测功能，用于检测是否需要关闭冰箱门。预设时间可以根据实际情况进行设定，例如，可以为1-5分钟之间的任意值，如2分钟或3分钟等。计算预设范围内无人状态的持续时间，持续时间大于或等于预设时间时，可以确定用户不再使用冰箱，可以关闭冰箱门，避免用户忘记关闭冰箱门的问题。
在本发明一个实施例中，在持续时间小于预设时间时，若通过人感检测 功能检测到预设范围内出现人体信号，获取人体信号的实时移动速度；
判断实时移动速度是否处于递减状态；
若否，继续累计预设范围内无人状态的持续时间。
在本实施例中，在计算预设范围内无人状态的持续时间的过程中，在持续时间小于预设时间时，若通过人感检测功能检测到预设范围内出现人体信号，为了确定该用户是否需要使用冰箱，可以获取人体信号的实时移动速度，判断实时移动速度是否处于递减状态，若实时移动速度未处于递减状态，则可以确定用户并不需要使用冰箱，可能只是在冰箱附近路过，因此，需要继续累计预设范围内无人状态的持续时间，从而可以提高计算无人状态的持续时间的准确性，进而提高判断是否需要关闭冰箱门的准确性。
在本发明一个实施例中，若实时移动速度处于递减状态，清除计算的无人状态的持续时间，待人体信号消失后，重新计算预设范围内无人状态的持续时间。
在本实施例中，若实时移动速度处于递减状态，可以确定用户需要使用冰箱，因此，清除计算的无人状态的持续时间，待人体信号消失后，重新计算预设范围内无人状态的持续时间，可以提高计算无人状态的持续时间的准确性。
图2是根据本发明另一个实施例的冰箱门的控制方法的流程图，参见图2，冰箱门的控制方法可包括步骤S202至步骤S216。
步骤S202：获取冰箱门的开闭状态。
步骤S204：启动与开闭状态对应的人感检测功能。人感检测功能检测冰箱预设范围内的人体状态，并根据人体状态控制冰箱门的开闭。
步骤S206：当开闭状态为关闭状态时，获取人体的实时移动速度。
步骤S208：判断人体至冰箱的距离是否小于预设距离。预设距离小于预设范围的边界至冰箱的距离。预设距离和预设范围均可以参照上述实施例，这里不再赘述。
若是，执行步骤S210，若否，执行步骤S216。
步骤S210：判断人体移动的方向是否为朝向冰箱的门体的方向。
若是，执行步骤S212，若否，执行步骤S216。
步骤S212：判断实时移动速度是否处于递减状态。
若是，执行步骤S214，若否，执行步骤S216。
步骤S214：打开冰箱门。
步骤S216：继续维持冰箱门的关闭状态。
图3是根据本发明另一个实施例的冰箱门的控制方法的流程图，参见图2，冰箱门的控制方法可包括步骤S302至步骤S318。
步骤S302：获取冰箱门的开闭状态。
步骤S304：启动与开闭状态对应的人感检测功能。人感检测功能检测冰箱预设范围内的人体状态，并根据人体状态控制冰箱门的开闭。
步骤S306：当开闭状态为打开状态时，计算预设范围内无人状态的持续时间。预设范围可以参照上述实施例，这里不再赘述。
步骤S308：判断持续时间是否大于或等于预设时间。
若是，执行步骤S310，若否，执行步骤S312。
步骤S310：关闭冰箱门。
步骤S312：若通过人感检测功能检测到预设范围内出现人体信号，获取人体信号的实时移动速度。
步骤S314：判断实时移动速度是否处于递减状态。
若是，执行步骤S316，若否，执行步骤318。
步骤S316：清除计算的无人状态的持续时间，待人体信号消失后，重新计算预设范围内无人状态的持续时间。
步骤S318：继续累计预设范围内无人状态的持续时间。
参见图4，基于同一构思，本发明还提供了一种冰箱400。冰箱400可包括存储器401和处理器402。存储器401内存储有控制程序，控制程序被处理器402执行时用于实现根据上述任一项实施例的冰箱门的控制方法。
具体地，冰箱400可通过人感传感器检测预设范围内的人体状态。冰箱400也可以通过多普勒雷达对获取预设范围内的人体的速度等。当冰箱门的开闭状态为关闭状态时，冰箱400可通过人感传感器获取预设范围内人体的实时移动速度。冰箱400判断实时移动速度是否处于递减状态，若是，打开冰箱门。当冰箱门的开闭状态为打开状态时，冰箱400计算预设范围内无人状态的持续时间，判断持续时间是否大于或等于预设时间，若是，关闭冰箱门。
上述各个实施例可以任意组合，根据上述任意一个优选实施例或多个优选实施例的组合，本发明实施例能够达到如下有益效果：
获取冰箱门的开闭状态，启动与开闭状态对应的人感检测功能，通过人感检测功能检测冰箱预设范围内的人体状态，并根据人体状态控制冰箱门的开闭，实现了对冰箱门的自动开闭，减少了用户的操作，方便了用户的使用，提高了用户的体验。
需要说明的是，在流程图中表示或在此以其他方式描述的逻辑和/或步骤，例如，可以被认为是用于实现逻辑功能的可执行指令的定序列表，可以具体实现在任何计算机可读介质中，以供指令执行系统、装置或设备(如基于计算机的系统、包括处理器的系统或其他可以从指令执行系统、装置或设备取指令并执行指令的系统)使用，或结合这些指令执行系统、装置或设备而使用。
应当理解，本发明的各部分可以用硬件、软件、固件或它们的组合来实现。在上述实施方式中，多个步骤或方法可以用存储在存储器中且由合适的指令执行系统执行的软件或固件来实现。例如，如果用硬件来实现，和在另一实施方式中一样，可用本领域公知的下列技术中的任一项或他们的组合来实现：具有用于对数据信号实现逻辑功能的逻辑门电路的离散逻辑电路，具有合适的组合逻辑门电路的专用集成电路，可编程门阵列(PGA)，现场可编程门阵列(FPGA)等。
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。
