具体实施方式
如图1-图6所示，本实施例提供了一种洗衣机门锁检测装置，包括控制盘座1，控制盘座1的一侧与上盖2转动连接，控制盘座1上安装有门锁的锁钩3，上盖2上设置有与锁钩3相配合的锁孔4，当上盖2关闭后，控制器可控制锁钩3伸出至锁孔4内，从而将上盖2锁定。可选地，在控制盘座1上锁钩3的出口处还设置有能够上下滑动的阻挡结构，该阻挡结构能阻止锁钩3的伸出动作；相应地，在上盖2上设有与阻挡结构相适配的推顶部6，用于向下推开阻挡结构，使锁钩3能够伸出到锁孔4内。
可选地，该门锁检测装置还包括用于检测上盖2开闭情况的门开关检测装置，当门开关检测装置检测到上盖2关闭时，可向控制器发出门关闭的信号，然后控制器控制锁钩3伸出，洗衣机启动洗涤或脱水程序。可选地，该门开关检测装置为设置在控制盘座1上的压力传感器，通过感应上盖2的压力判断上盖2是否闭合。但是在工作中，该门开关检测装置可能在上盖2未关闭到位时，错误发出门关闭的信号，此时由于阻挡结构的存在，可阻止锁钩3的正常伸出，然后门锁将未锁紧信号发送至控制器，阻止洗衣机运转；若上盖2关闭到位，则由于推顶部6向下推开阻挡结构，此时锁孔4与锁钩3的位置恰好相对，锁钩3可伸入至锁孔4内将上盖2锁紧，之后门锁将锁紧信号发送至控制器，控制洗衣机正常运转。这里，可以在门锁内设置电磁开关，当锁钩3伸出受阻时，该电磁开关断开，并反馈门未锁紧信号给控制器；当锁钩3伸入锁孔4内时，该电磁开关闭合，并反馈门已锁紧信号给控制器。
本实施例通过在锁钩3出口处设置阻挡结构，能够防止锁钩3在上盖2未关闭到位情况下伸出，有效避免了门锁向洗衣机发出错误的操作信号，从根本上避免了洗衣机上盖2在未锁紧状态下运行的危险，大大提高了洗衣机的安全使用性。本实施例的门锁检测装置既适用于平移伸出式的锁钩3，也适用于转动伸出式的锁钩3，这两种方式的设置如下：
1)如图1-图2所示，该锁钩3为平移伸出式，阻挡结构为设置在锁钩3伸出方向的限位块51，限位块51的底部固设有弹簧，使限位块51在正常状态下阻挡于锁钩3的出口处，在受到上盖2的推顶部6推动后向下移动，打开锁钩3的出口。这里，推顶部6位于上盖2的底部，该推顶部上设有平滑倒角，同时限位块51的顶端也设有平滑倒角，用于与上盖2的推顶部6相配合，实现该检测装置的平稳运动。此种方式的锁钩3和阻挡结构，设计简单，制作方便，大大节省了洗衣机的生产成本。
2)如图3-图6所示(图中省略上盖)，该锁钩3为转动伸出式，阻挡结构为安装在控制盘座1内的限位柱52。可选地，控制盘座1上靠近锁钩3的位置开设有限位孔7，限位柱52活动安装在限位孔7内，限位柱52的下部套设有弹簧，使限位柱52在自然状态下(即上盖2打开时)，保持顶端伸出限位孔7之外，此时，由于限位柱52处于锁钩3的转动方向上，从而使锁钩3的转动受到限制，无法伸出。上盖2上相应的位置处设有推顶部6，该推顶部6可为设在锁孔4一侧的按压块，在上盖2闭合的过程中，该按压块与限位柱52的顶端相接 触，将限位柱52压下缩进限位孔7内，此时，限位柱52对锁钩3的限制被解除，锁钩3能够转动伸出，并与锁孔4完好配合，从而将上盖2锁紧。可选地，限位柱52的顶端设有平滑倒角，用于与上盖2的推顶部6相配合；限位柱52的底端开设有限位槽，限位槽内装有e型挡圈，能够限制限位柱52向上运动的位移，防止限位柱52从限位孔7中滑落。
另外，本实施例的锁钩3和锁孔4可以设置一组，也可以设置为多组，锁钩3可采用联动式结构，其中一个或多个锁钩3的出口处设置有上述阻挡结构，这样只要有一组锁钩3受到阻挡，其它锁钩3均无法伸出，保证了上盖2与控制盘座1的锁紧安全性。如图7、图8所示，本实施方式中控制盘座1上设有两组转动伸出式锁钩，分别为主动侧锁钩31和从动侧锁钩32，两锁钩3之间通过连杆33或拉带连接，工作时，控制器控制主动侧锁钩31伸出，同时带动从动侧锁钩32发出相同动作。
本实施例利用推顶部6与阻挡结构的准确配合，当上盖2关闭到位时可将上盖2牢固锁紧，其结构简单，运动过程精确，工作安全可靠，解决了门锁在锁定上盖2过程中，容易因检测信号不准、锁舌错误伸出而导致的洗衣机安全问题。
本实施例提供一种洗衣机门锁检测方法，包括：在洗衣机下发门锁启动信号后，利用上述实施例任一项所述的门锁检测装置对门锁的状态进行检测。
可选地，如图9所示，洗衣机门锁检测方法包括：
洗衣机启动；
检测上盖2开闭状态；
该步骤中，由洗衣机的门开关检测装置对上盖2的开闭状态进行检测，若检测到上盖2关闭，则向控制器发出门关闭的信号，并进入后续步骤；若检测到上盖2打开，则返回重新检测上盖2开闭状态。
下发门锁启动信号；
其中，控制器控制门锁的锁钩3发生动作向外伸出，以便与上盖2上的锁孔4相配合。
利用门锁检测装置检测门锁的锁钩3是否伸出锁上上盖2，若上盖2已锁上，则开始洗涤或脱水程序；若上盖2未锁上，则重新下发门锁启动信号；若下发三次门锁启动信号后，仍未反馈门锁锁上信号，则报警提示上盖2未闭合到位。
本实施例中，由于门锁检测装置在锁钩3处设置了阻挡机构，当控制器下 发门锁启动信号后，门锁的锁钩3不一定能顺利伸出，只有在上盖2真正闭合时，门锁的锁钩3方可伸至上盖2的锁孔4内，将上盖2锁紧，此时门锁将锁紧信号反馈给控制器，控制洗衣机正常使用；而当上盖2打开或未闭合到位时，阻挡结构阻止锁钩3伸出，此时门锁将阻挡信号反馈给控制器，控制器在连续三次接到阻挡信号后，则发出报警提示用户上盖2没有盖好。该检测过程准确可靠，有效解决了洗衣机门锁因检测信号不准、锁钩错误伸出而造成的洗衣机安全隐患。
