图1是本发明在方案一中的洗衣机安全检测方法的主要流程图。
图2是本发明在方案二中的洗衣机安全检测方法的主要流程图。
为使本发明的实施例、技术方案和优点更加明显，下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所述的实施例是本发明的一部分实施例，而不是全部实施例。本领域技术人 员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。
在方案一中：
参照图1，图1是本发明的洗衣机安全检测方法的主要流程图。如图1所示，本发明的安全检测方法包括下列步骤：S110、在洗衣机运行阶段，当检测到洗衣机盖从闭合状态切换回打开状态时，检测洗衣桶的第一状态信息；S120、当检测到洗衣机盖从打开状态切换为闭合状态时，再次检测洗衣桶的第二状态信息；S130、比较第二状态信息和第一状态信息，根据比较结果选择性地发出警报提示信息。通过上述方案，在洗衣运行过程中，如果洗衣机盖打开过(即洗衣机盖打开后再关上的情形)，且该过程中洗衣机盖的打开和关闭是通过远程控制(如远程服务器控制或用户利用终端远程控制，洗衣机盖的打开也可以是其他原因导致的打开)，一旦在洗衣机盖打开再关闭这个过程中有生物体或非生物体进入到洗衣桶内，即可通过第二状态信息和第一状态信息的比较结果判断出来，进而发出警报提示信息以提醒用户，防止洗衣桶内因进入生物体或非生物体后继续运行而出现危险。也就是说，本发明的方案可以消除洗衣机运行过程中因洗衣机盖打开而存在的潜在危险。
具体而言，在步骤S110-S130中，洗衣机运行阶段包括洗涤阶段和漂洗阶段。
作为示例，第一状态信息为洗衣桶的第一重量，第二状态信息为洗衣机的第二重量。也就是说，在洗衣机洗涤阶段或漂洗阶段，洗衣机盖一旦打开，则检测洗衣桶当前的重量，当洗衣机盖恢复闭合后，再次检测洗衣桶的重量。然后比较两次检测到的洗衣桶的重量来判断是否有生物体或非生物体进入到洗衣桶内。更具体地，当洗衣桶的第二重量超过第一重量第一阈值(本领域技术人员可以灵活地设置第一阈值以选择合适的精度)时，则说明有异物进入到洗衣桶内，此时发出警报提示信息。举例而言，假如在洗衣机运行阶段，洗衣机盖打开后，由于用户不在洗衣机旁边，一旦宠物进入到洗衣桶内，而洗衣机盖又恰好闭合，此时洗衣桶的重量会明显增大，为了宠物的生命安全，发出警报提示信息提示用户。
作为示例，第一状态信息为洗衣桶内的第一水位，第二状态信息为洗衣桶内的第二水位。由于在洗涤阶段或漂洗阶段，一旦有异物进入到洗衣桶内，洗衣桶内的水位会出现上升，同时异物进入洗衣桶内后会进一步增加对洗衣桶的晃动幅度，因此，当检测到第二水位超过第一水位第二阈值(本领域技术人员可以灵活地设置第二阈值以选择合适的精度)时，则检测洗衣桶的晃动幅度，当洗衣桶的晃动幅度超过第三阈值(本领域技术人员可以灵活地设置第三阈值以选择合适的精度)时，则发出警报提示信息。举例而言，假如在洗衣机运行阶段，洗衣机盖打开后，由于用户不在洗衣机旁边，一旦宠物进入到洗衣桶内，而洗衣机盖又恰好闭合，此时洗衣桶内的水位会明显升高，而且洗衣桶的晃动幅度也会出现明显增加，为了宠物的生命安全，发出警报提示信息提示用户。
作为示例，为了进一步提高判断准确度，第一状态信息可以是洗衣桶的第一重量和洗衣桶内的第一水位，第二状态信息为洗衣桶内的第二水位。这样一来，通过比较第一重量和第二重量，以及比较第一水位和第二水位，来共同判断是否有生物体或非生物体进入到洗衣桶内。例如，当洗衣桶的第二重量减去洗衣桶的第一重量超过第一阈值，并且第二水位减去第一水位的值超过第二阈值时，发出警报提示信息，从而提高了判断的准确度。
在上述步骤S130中，警报提示信息可以是洗衣机发出的峰鸣音、语音提示或灯光提示；也可以是用户终端接收到的峰鸣音、语音提示或短信提示。例如，在判断出洗衣桶内有异物进入后，可以由洗衣机可以发出峰鸣音、语音提示音或闪烁的灯光以提醒用户，也可以向用户的手机发送短信提示、峰鸣音提示或者语音提示以提醒用户。本领域技术人员可以选择任意合适的方式发出警报提示信息以提示用户。
本发明还提供了一种洗衣机，其包括控制器，该控制器配置成用于执行上述的洗衣机安全检测方法。
在方案二中：
参照图2，图2是本发明的洗衣机安全检测方法的主要流程图。如图2所示，本发明的安全检测方法包括下列步骤：S110、在洗衣 机脱水阶段，当检测到洗衣机盖从闭合状态切换为打开状态时，检测洗衣桶的第一状态信息；S120、当检测到洗衣机盖从打开状态切换回闭合状态时，再次检测洗衣桶的第二状态信息；S130、比较第二状态信息和第一状态信息，根据比较结果选择性地发出警报提示信息。通过上述方案，在洗衣机脱水阶段，如果洗衣机盖打开过(即洗衣机盖打开后再关上的情形)，且该过程中洗衣机盖的打开和关闭是通过远程控制(如远程服务器控制或用户利用终端远程控制，洗衣机盖的打开也可以是其他原因导致的打开)，一旦在洗衣机盖打开再关闭这个过程中有生物体或非生物体进入到洗衣桶内，即可通过第二状态信息和第一状态信息的比较结果判断出来，进而发出警报提示信息以提醒用户，防止洗衣桶内因进入生物体或非生物体后继续运行而出现危险。也就是说，本发明的方案可以消除洗衣机运行过程中因洗衣机盖打开而存在的潜在危险。
作为示例，第一状态信息为洗衣桶的第一重量，第二状态信息为洗衣机的第二重量。也就是说，在洗衣机脱水阶段，洗衣机盖一旦打开，则检测洗衣桶当前的重量，当洗衣机盖恢复闭合后，再次检测洗衣桶的重量。然后比较两次检测到的洗衣桶的重量来判断是否有生物体或非生物体进入到洗衣桶内。更具体地，当洗衣桶的第二重量超过第一重量第一阈值(本领域技术人员可以灵活地设置第一阈值以选择合适的精度)时，则说明有异物进入到洗衣桶内，此时发出警报提示信息，否则不发出警报提示信息。举例而言，假如在洗衣机运行阶段，洗衣机盖打开后，由于用户不在洗衣机旁边，一旦宠物进入到洗衣桶内，而洗衣机盖又恰好闭合，此时洗衣桶的重量会明显增大，为了宠物的生命安全，发出警报提示信息提示用户
作为另一种示例，第一状态信息为洗衣桶的第一重量，第二状态信息为洗衣机的第二重量。由于异物进入洗衣桶内后会进一步增加对洗衣桶的晃动幅度，因此，当洗衣桶的第二重量超过第一重量第一阈值(本领域技术人员可以灵活地设置第一阈值以选择合适的精度)时，则检测洗衣桶的晃动幅度，当洗衣桶的晃动幅度超过第二阈值(本领域技术人员可以灵活地设置第二阈值以选择合适的精度)时， 则发出警报提示信息。在该实施例中，在比较第一重量和第二重量的基础上，再结合晃动幅度来提高判断的准确度。
作为另一种示例，第一状态信息为洗衣桶的第一重量，第二状态信息为洗衣机的第二重量。当洗衣桶的第二重量超过第一重量第一阈值(本领域技术人员可以灵活地设置第一阈值以选择合适的精度)时，则获取洗衣桶内的光线传感器检测到的信息。如果光线传感器检测到的信息为透光信息，则不发出警报提示信息；如果光线传感器检测到的信息为不透光信息，则发出警报提示信息。具体而言，由于洗衣机脱水阶段，洗衣桶内无水，而衣物一般会在贴着洗衣桶壁的位置，此时，在洗衣桶内安装光线传感器的情形下，一旦光线传感器检测到不透光信息，则说明洗衣桶内进入了异物(例如宠物)，此时发出警报提示信息。该实施例中，在比较第一重量和第二重量的基础上，再结合洗衣桶内的光线传感器检测的数据来提高判断的准确度。
在上述步骤S130中，警报提示信息可以是洗衣机发出的峰鸣音、语音提示或灯光提示；也可以是用户终端接收到的峰鸣音、语音提示或短信提示。例如，在判断出洗衣桶内有异物进入后，可以由洗衣机可以发出峰鸣音、语音提示或闪烁的灯光以提醒用户，也可以向用户的手机发送短信提示、峰鸣音提示或者语音提示以提醒用户。本领域技术人员可以选择任意合适的方式发出警报提示信息以提示用户。
本发明还提供了一种洗衣机，其包括控制器，该控制器配置成用于执行上述的洗衣机安全检测方法。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
