在本申请中，除非另有明确的规定和限定，术语“连接”、“固定”等应做广义理解，例如，“固定”可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
另外，在本申请中如涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
一些家用电器中，如洗碗机、洗衣机、微波炉、烤箱等，具有门锁，门体通过门锁锁定或释放。以洗碗机为例，洗碗机是一种可以自动清洗餐具的设备，一般来说洗碗机包括机体和门体，机体具有洗涤腔，洗涤腔内设置有碗篮，餐具放置在碗篮内，碗篮可拉出或推入洗涤腔，门体用于关闭洗涤腔。在门体关闭洗涤腔时，门体通过门锁锁定于机体，此时洗涤腔内可进行相应的洗涤过程或干燥过程，在门体 需要打开时，用户拉动门体，门体脱离门锁的锁定从而打开洗涤腔，也就是说，这种门锁是一种可以实现锁定，且可在外力的作用下实现解锁的装置。这样就会导致，若洗碗机在进行一些高温操作时，用户尤其是小孩若在误操作的情况下将门体拉开，会出现高温烫伤的风险。因此本申请提出一种这样的门锁，该门锁实现锁定，可防止或阻止用户误开锁。
本申请中以洗碗机为例对门锁进行说明，可以理解的是，本申请中的门锁还可以用于其它家用电器或一些需要用门锁进行锁定门体的装置，如前面所提到的洗衣机、微波炉等。
如图1所示，一种门锁，包括锁舌100、锁芯200、锁栓310、约束机构400和第一驱动件500。在一些实施例中，锁舌100可以设置在门体上，锁芯200则可以设置在机体，在另一些实施例中，锁舌100可以设置在机体上，锁芯200则可以设置在门体，可以根据实际需求而安排锁舌100和锁芯200。锁舌100是一种和锁芯200相互配合实现锁定或释放的结构，它们可以在力的作用下分离或闭合，如用户拉动门体打开时，锁舌100和锁芯200分离，用户推动门体关闭时，锁舌100和锁芯200锁闭，锁舌100和锁芯200的具体的形式可以根据实际情况进行选择。在本实施例中，以锁舌100设置在门体、锁芯200设置在机体为例进行说明。
一般来说，锁舌100可采用金属材料制造而成，如通过铁、铝等铸造而成单个零部件，具有较高的强度。门体一般具有内门体和外门体，内门体的顶部具有安装位，锁舌100通过螺纹紧固件固定在门体的顶部的安装位。除此之外，还可以通过在门体的顶部冲压成型锁舌100。锁舌100能跟随着门体的移动而移动，在门体需要关闭时，锁舌100随着门体而插入锁芯200内，从而被锁芯200锁紧，在门体需要打开时，锁舌100随着门体而脱离锁芯200。可以理解的是，在锁舌100插入锁芯200时，锁芯200要想完成对锁舌100的锁定，锁芯200必须要进行相应的活动才能锁定锁舌100，而对于锁舌100脱离锁芯200时也是如此，锁芯200要进行相应的活动才能释放锁舌100，也就是说锁芯200在锁定锁舌100或释放锁舌100时是活动的。
正如此，用户通过拉动或推动门体即可实现门体的开闭，但是在洗碗机处于工作时，若门体被误打开会造成相应的危险。因此通过设置锁栓310，该锁栓310能在洗碗机达到某种运行条件时自动限制锁舌100或锁芯200的活动，从而防止锁舌100和锁芯200相分离。
具体地，当洗碗机收到信号需要对锁芯200或锁舌100进行限制时，第一驱动件500驱动锁栓310动作以限制锁舌100或锁芯200的活动，锁舌100便不能随着门体的打开而打开，即锁舌100和锁芯200不能分离，门体依然保持着关闭状态，这里的限制即为施加给锁舌100或锁芯200极大的阻碍，从而防止门体被强行拉开时锁芯200和锁舌100相互分离，或者说能大大增加门体被打开的阻力，以便让用户识别到此时是不能打开门体的，从而防止锁舌100和锁芯200的分离导致的门体被打开。不同的锁舌100和锁芯200具体的结构不同，从而使得锁舌100和锁芯200的锁定或释放具有多种方式，但是锁舌100必定是要跟随着门体移动的，只要锁栓310能制约锁舌100跟随门体移动即可。
通过设置约束机构400，约束机构400具有两个约束位置，分别为第一约束位置以及第二约束位置，锁栓310可处于第一约束位置或第二约束位置，在锁栓310处于第一约束位置时，锁栓310受限于第一约束位置而不能动作，此时锁栓310对锁舌100或锁芯200形成限制，锁栓310处于第二约束位置时，锁栓310受限于第二约束位置而不能动作，此时锁栓310对锁舌100或锁芯200非限制。意味着，第一驱动件500只需要将锁栓310驱动使得锁栓310能到达第一约束位置或第二约束位置即可，第一驱动件500随后即可断电从而复位，此时锁栓310在约束机构400的作用下是保持不动的，这样就不用长时间对第一驱动件500进行通电工作，节省电力，而且还能降低第一驱动件500的发热量，提高安全性。
可以理解的是，前文提到的第一驱动件500驱动锁栓310脱离第一约束位置以使锁栓310到达第二约束位置，包含着多种情况，即第一驱动件500可以在驱动锁栓310脱离第一约束位置后，锁栓310在其它部件的作用下到达第二约束位置，还可以是第一驱动件500驱动锁栓310自第一约束位置移动到第二约束位置。
同样如此，前文提到的第一驱动件500驱动锁栓310脱离第二约束位置以使锁栓310到达第一约束位置，包含着多种情况，即第一驱动件500驱动锁栓310脱离第二约束位置后，锁栓310在其它部件的作用下到达第一约束位置；还可以是第一驱动件500驱动锁栓310自第二约束位置移动到第一约 束位置。
进一步地，如图1所示，可以在锁栓310的移动路径上设置有微动开关340，在锁栓310脱离第二约束位置而到达第一约束位置的时候，锁栓310便能触碰微动开关340，微动开关340从而产生信号，从而可在洗碗机上显示为上锁状态；在锁栓310脱离第一约束位置而到达第二约束位置的时候，锁栓310与微动开关340分离，微动开关340的信号断开，从而可以在洗碗机上显示为非上锁状态。
由上可知，所述锁舌100和所述锁芯200构成了锁结构，可正常实现门体的启闭，在所述锁栓310进行锁定时，相当于在所述锁舌100和所述锁芯200所构成的锁结构上增设了一道机械防护装置，通过所述锁栓310对所述锁舌100或所述锁芯200进行约束，从而可以有效防止门体被强行拉开，或大大增加门体被拉开的阻力，避免出现危险。例如，在洗碗机处于高温漂洗的过程时，此时洗碗机的洗涤腔内的喷臂处于旋转喷射高温高压水流，若此时门体被强行拉开，则高温高压水流容易喷射出洗碗机外，对用户造成伤害，而通过锁栓310的作用，则有效避免了这种情况的发生。
如图1、图2和图3所示，在本申请的一些实施例中，在所述锁栓310处于所述第二约束位置的时候，也即锁栓310不对所述锁舌100或所述锁芯200形成限制，锁栓310存在着自第二约束位置向第一约束位置运动的趋势。这种运动趋势，即锁栓310受到一个驱动力，该驱动力能驱动锁栓310移动，只是目前锁栓310受阻而不能移动。锁栓310具有朝向第一约束位置的运动趋势，也即是锁栓310在第二约束位置时，具有朝向对锁舌100或锁芯200进行限制的位置运动的趋势。如此，锁栓310脱离第二约束位置后，能在这种驱动力的作用下到达第一约束位置，实现快速上锁，从而提高锁栓310的锁定效率。这种运动趋势可由多种方式实现，例如通过重力使锁栓310向下掉落以使锁栓310具有运动趋势，或者通过将锁栓310磁化，设置磁铁或电磁铁对锁栓310进行吸取以使锁栓310具有运动趋势。
可以理解的是，第一驱动件500驱动锁栓310脱离第二约束位置后，锁栓310除了在运动趋势的作用下运动外，还可以在第一驱动件500的作用下运动，也就是对锁栓310产生运动趋势的驱动力和第一驱动件500的驱动力叠加，使得锁栓310快速动作。但是，在本申请的一些实施例中，不使用第一驱动件500的驱动力叠加，具体为第一驱动件500动作，驱动锁栓310脱离第二约束位置，在此过程中第一驱动件500断电复位，锁栓310在上述提到的运动趋势的作用下顺利到达第一约束位置。也即，第一驱动件500的作用在于将锁栓310带离第二约束位置，第一驱动件500即可断电复位，如此第一驱动件500不需要长时间对锁栓310产生动作，如图8和图9所示，在约束机构400的作用下，第一驱动件500驱动锁栓310朝左运动到最大位置以脱离第二约束位置后，第一驱动件500即可复位，锁栓310在产生运动趋势的驱动力的作用下朝右运动到第一约束位置，避免第一驱动件500长时间通电。
对于锁栓310脱离第一约束位置也是如此，如图4、图5和图6所示，在本申请的一些实施例中，所述第一驱动件500动作，驱动所述锁栓310脱离所述第一约束位置，在此过程中所述第一驱动件500断电复位，所述锁栓310在上述提到的所述运动趋势的作用下顺利到达所述第二约束位置。在约束机构400的作用下，第一驱动件500驱动锁栓310朝左运动到最大位置(此最大位置与前述最大位置不可以相同也可以不同)，第一驱动件500即可断电复位，锁栓310在产生运动趋势的驱动力的作用下朝右运动到第二约束位置，避免第一驱动件500长时间通电。
如图1至图9所示，在本申请的一些实施例中，所述锁栓310设置有弹性件320，在所述锁栓310位于约束机构400的所述第二约束位置时，所述弹性件320能对所述锁栓310产生力，从而使所述锁栓310具有自所述第二约束位置朝向所述第一约束位置运动的趋势；
所述第一驱动件500的作用在于驱动所述锁栓310脱离所述第二约束位置，所述锁栓310在所述弹性件320的作用下到达所述第一约束位置，或在于驱动所述锁栓310脱离所述第一约束位置，所述锁栓310在所述弹性件320的作用下到达所述第二约束位置。
具体地，在本实施例中，锁栓310的运动趋势来源于弹性件320，弹性件320可以是拉绳、拉簧等，通过弹性件320产生驱动力以简化锁栓310实现运动趋势的结构，可以单独通过机械结构的方式使得锁栓310具有运动趋势，避免使用电子元器件。
在需要锁栓310上锁时，第一驱动件500对锁栓310产生动作，锁栓310脱离第二约束位置后第一驱动件即可500复位，第一驱动件500不会对锁栓310形成阻碍，弹性件320随即伸展，从而使得 锁栓310移动至第一约束位置。在需要锁栓310解锁时，第一驱动件500对锁栓310动作，锁栓310脱离第一约束位置向左运动，第一驱动件500复位，弹性件320随即伸展，从而使得锁栓310移动至第二约束位置。
在本申请的一些实施例中，如图1至图9所示，所述弹性件320以压缩的方式以对处在第二约束位置的所述锁栓310产生推力。由于通过弹性件320压缩以产生推力，使得锁栓310具有运动趋势，也就是说，弹性件320和锁栓310的运动方向是一致的，弹性件320向左压缩，锁栓310向左移动，弹性件320向右压缩，锁栓向右移动从而使得弹性件320和锁舌100，或弹性件320和锁芯200可以分布在锁栓310的两侧，方便零部件的排布，也能使得整个门锁做得更薄。若弹性件320拉伸以对锁栓310产生拉力使得锁栓310具有运动趋势，这种情况也是可以，但是弹性件320需要和锁舌100或锁芯200布置于锁栓310的同一侧，为了避免弹性件320和锁舌100或锁芯200的活动干涉，因此需要将弹性件320和锁芯200或锁舌100分布在不同的运动平面，如此将会增加门锁的厚度，或者增加额外的传动机构，这使得整个门锁变得复杂。
进一步地，如图1所示，在本申请的一些实施例中，以锁舌100脱离与插入锁芯200的方向为第一方向(图示前后方向)，和第一方向垂直的则为第二方向(图示左右方向)，锁栓310和弹性件320在第二方向上依次排布于所述锁舌100的一侧。具体地，弹性件320的一端连接到锁栓310的一端，具体的连接方式有多种，例如粘接固定，熔接固定，或者在锁栓310的一端设置有连接柱，而弹性件320的一端套设于这个连接柱，这样便能实现弹性件320和锁栓310的连接。而弹性件320另一端被固定，如下文提到的，弹性件320的另一端固定在下壳体620上，下壳体620上也设置有相应的连接柱，弹性件320的另一端套设在下壳体620的连接柱上。如此，弹性件320可以直接驱动锁栓310运动，而且不需要通过中间件即可实现锁栓310的移动，使得锁栓310做的更薄的情况下，重量更轻，而且不会影响锁舌100和锁芯200。
为了更便于对锁栓实现限制于第一约束位置或第二约束位置。在本申请的一些实施例中，如图4至图9所示，所述锁栓310上设有可相对于所述锁栓310活动的限位杆330，所述锁栓310通过该限位杆330能够约束于所述第二约束位置或所述第一约束位置；
约束机构400设有第一路径450与第二路径460，第一路径450与第二路径460形成环路，限位杆330可以从第二约束位置沿着第一路径450移动至第一约束位置，或从第一约束位置沿着第二路径460移动至第二约束位置。
具体地，限位杆330是一种能将锁栓310约束在第一约束位置或第二约束位置的部件，由于限位杆330的设置，锁栓310即使具有运动趋势，也能受限于第一约束位置或第二约束位置而保持不动，也即限位杆330的结构形式可以有多种，在此不做限定，只要能实现对锁栓310的限制即可。例如，如图1和图16所示，限位杆330包括杆体331，杆体331高于下文提及的约束机构400的第一挡块410和第二档块420，沿杆体331的第一端弯折设有第一弯折体332，沿杆体331的第二端弯折设有第二弯折体333，第二弯折体333和第一弯折体332相对于杆体331的弯折方向相反，第一弯折体332通过通孔314活动连接锁栓310，第二弯折体333活动连接于约束机构400，即第二弯折体333能在第一约束位置和第二约束位置之间通过第一路径450或第二路径460移动。
限位杆330相对锁栓310可活动设置，是便于限位杆330能灵活跟随锁栓310的移动而发生位置上的相应变化，从而实现在第一约束位置或第二约束位置之间移动。如图所示的，锁栓310设有通孔314，限位杆330的一端插入通孔且可转动，限位杆330另一端则在第一约束位置与第二约束位置之间沿着第一路径450与第二路径460移动，在限位杆330发生移动时，限位杆330能绕通孔314发生相应的转动。通过设置第一路径450与第二路径460，在限位杆330移动时，第一路径450与第二路径460相当于对限位杆330形成一定制约，限位杆330的移动更可靠，能保证限位杆330顺利在第一约束位置与第二约束位置之间移动，而且第一路径450与第二路径460形成的是环路，从而可以实现最大化的简化约束机构400的结构。
进一步地，在本申请的一些实施例中，如图5、图6、图8、图9、图11和图12所示，约束机构400包括：
第一挡块410，设置有第一凹口411，所述第一凹口411构成所述第二约束位置；
第二挡块420，和第一挡块410相间隔设置，以形成与所述第一凹口411连通的第一通口421与第二通口422；
第一引导槽430，设置在所述第一挡块410的一侧，且和所述第一通口421连通；
第二引导槽440，设置在所述第一挡块410的另一侧，且和所述第二通口422连通，所述第二引导槽440还和所述第一引导槽430连通，并且两者的连通处形成第一约束位置，第二引导槽440与第一引导槽430共同环绕着第一挡块410设置；
第一通口421和第一引导槽430构成为第一路径450，第二引导槽440和第二通口422构成为第二路径460。
具体地，可以在下文提到的下壳体620上一体成型有约束机构400，第一挡块410呈V型结构或U型结构，V型结构或U型结构形成的第一凹口411形构成第二约束位置，第一凹口411朝向图示的左侧。当洗碗机接收到信号需要锁栓310上锁时，第一驱动件500驱动锁栓310移动，锁栓310自第一凹口411向左运动，此过程弹性件320会出现压缩，锁栓310带动限位杆330穿过第一通口421从而滑入第一引导槽430，然后，第一驱动件500复位，在弹性件320的作用下，锁栓310朝向右侧移动，直至限位杆330移动至第一约束位置，此时锁栓310锁定锁舌100或锁芯200。
当洗碗机接收到信号需要锁栓310解锁时，第一驱动件500对锁栓310产生动作，锁栓310移动，锁栓310朝左运动脱离第一约束位置，在锁栓310移动过程弹性件320压缩，随后第一驱动件500复位，在弹性件320的作用下，锁栓310朝右侧移动，从而带动限位杆330穿过第二通口422，而使限位杆330移动至第一凹口411(第二约束位置)，此时锁栓310非限制锁舌100或锁芯200。本申请例中，如下文提到的上壳体610和下壳体620，通过在下壳体620上直接成型了约束机构400，不需要额外设置约束机构400，方便对锁栓310形成限制。
进一步地，如图5、图6、图8和图9所示，为了方便在限位杆330脱出第二约束位置时能顺利地进入第一引导槽430，在一些实施例中，所述第一挡块410与所述第二挡块420在所述第一约束位置至所述第二约束位置的方向上依次设置(由右至左的方向)，所述第二挡块420设置有第一引导面423，所述第一引导面423和所述第一挡块410之间形成有所述第一通口421，所述第一引导面423设置于所述限位杆330脱离所述第一凹口411的方向上(图示由右至左的方向)，并且在所述限位杆330脱离所述第一凹口411的这一过程中，所述限位杆330触碰到所述第一引导面423从而穿过所述第一通口421以滑入所述第一引导槽430。由于第一路径450和第二路径460形成环路，为了避免限位杆330在脱离第一凹口411时进入第二引导槽440，通过对第一引导面423的设置，使得限位杆330利地进入第一引导槽430。
进一步地，为了防止限位杆330脱出第二约束位置后且朝向第一约束位置运动的过程中重新通过第一通口421移入第二约束位置。如图5、图6、图8和图9所示，在本申请的一些实施例中，所述第一引导面423相对于所述第一挡块410，朝向所述第一引导槽430而突出，从而使得所述限位杆330穿过所述第一通口421而顺利滑入所述第一引导槽430后，能够随所述锁栓310的运动而越过所述第一通口421，从而沿所述第一引导槽430移动至所述第一约束位置。
具体地，第一引导面423呈倾斜状，并且相对于第一挡块410，更加朝前突出，也即是，在限位杆330跟随锁栓310朝向第一约束位置移动的路径上，第一挡块410和第二挡块420并不是共线设置的，形成一定的错位。当洗碗机接收到信号需要锁栓310上锁时，第一驱动件500驱动锁栓310移动，锁栓310自第一凹口411向左运动，弹性件320出现压缩，限位杆330穿过第一通口421而滑入第一引导槽430，然后第一驱动件500复位，锁栓310在弹性件320的作用下朝向右侧移动，由于第二挡块420形成了更加突出的第一引导面423，因此限位杆330能随着锁栓310的移动而越过第一通口421，直至限位杆330移动至第一约束位置，此时锁栓310处于锁定锁舌100或锁芯200的状态。在本实施例中，通过对第一引导面423的设置，使得限位杆330在跟随锁栓310向第一约束位置移动的过程中，不会沿着反方向重新进入第一凹口411。
如图5、图6、图8和图9所示，，为了防止限位杆330自第一约束位置移动至第二约束位置的过程中，沿着第一路径450逆向移动，在本申请的一些实施例中，所述第一挡块410设置有第二引导面412，所述第二引导面412处于所述限位杆330脱离所述第一约束位置的方向上(图示由右至左的方向)，在 所述限位杆330受驱动而脱离所述第一约束位置的过程中，所述限位杆330触碰到所述第二引导面412而沿所述第二引导槽440移动。
可以理解的是，假如第一约束位置和第二路径460的至少部分共线设置，那么便可以不在第一挡块410上设置第二引导面412，限位杆330在脱离第一约束位置时，即可沿第二路径460移动。
进一步地，如图5、图6、图8和图9所示，所述第二引导槽440设置有第三引导面441，所述第一挡块410与所述第三引导面441在所述第一约束位置至所述第二约束位置的方向上(图示由右至左的方向)依次设置，在所述限位杆330脱离所述第一约束位置的这一过程中，所述限位杆330触碰到所述第三引导面441，从而跟随所述锁栓310穿过所述第二通口422以移动至所述第二约束位置。具体地，在限位杆330跟随锁栓310朝向第二约束位置移动的路径上，第一挡块410和第三引导面441不是共线设置的，形成一定的错位，如此，在洗碗机收到信号需要解锁时，第一驱动件500驱动锁栓310复位(向左运动)，锁栓310带动限位杆330脱离第一约束位置，限位杆330沿着第二路径460移动，在移动到预定位置时，第一驱动件500复位，锁栓310在弹性件320的驱动下朝向右运动，由于设置了第三引导面441，从而使得限位杆330可以顺利通过第二通口422移入第二约束位置，而不会沿着第二路径460的反方向移动。
由上可知，本申请通过设置约束机构400，在需要锁栓310上锁时，第一驱动件500驱动锁栓310朝左运动时，锁栓310带动限位杆330脱离第一凹口411，并触碰到第一引导面423从而滑入第一引导槽430，随后第一驱动件500复位，锁栓310在弹性件320的作用下越过第一通口421而朝向第一约束位置移动。在需要锁栓310解锁时，第一驱动件500驱动锁栓310朝左运动，锁栓310带动限位杆330脱离第一约束位置，并触碰到第二引导面412而沿着第二引导槽440中移动，在移动过程中触碰到第三引导面441而越过第二通口421，随后第一驱动件500复位，锁栓310在弹性件320的作用下带动限位杆330到达第二约束位置，即第一凹口411，如此完成了上锁和解锁的过程。
如图1所示，在本申请的一些实施例中，第一驱动件500的驱动方向(图示上下方向)和锁栓310的运动方向(图示左右方向)相交。也即锁栓310的移动是一种直线往复式的移动，第一驱动件500的驱动也是一种直线往复式的驱动，如此排布第一驱动件500和锁栓310，能充分利用空间，避免第一驱动件500和锁栓310同向设置导致的门锁长度过程，或叠合设置导致的门锁厚度过大。
进一步地，如图1、图11和图13所述，在本申请的一些实施例中，第一驱动件500包括第一驱动器510和设于第一驱动器510的驱动端的第一推杆520，所述第一推杆520设有第一接触面521，锁栓310设有第二接触面313，第一驱动器510通过第一接触面521与第二接触面313相抵以驱动锁栓310。具体地，第一驱动器510是一种通电后执行相应动作的元器件，第一驱动器510可以采用多种形式，例如往复式第一驱动器、旋转式第一驱动器等，只要能实现第一推杆520的往复式驱动即可，本实施例中以往复式第一驱动器510为例。锁栓310安装在下文提到的下壳体620的滑轨上，锁栓310可于滑轨往复运动，锁栓310设有穿口315，可让第一推杆520穿设，穿口315中设置第二接触面313，在锁栓310处于第二约束位置时，第一驱动器510驱动第一推杆520，第一推杆520伸展以让第一接触面521的前端和第二接触面313的前端接触，随着第一推杆520的伸展，锁栓310朝左运动以使限位杆330脱离第二约束位置，随后第一驱动器510带动第一推杆520复位，锁栓310在弹性件320的作用下向右带动限位杆330运动到第一约束位置。在锁栓310位于第一约束位置时，第一驱动器510驱动第一推杆520，第一推杆520伸展以让第一接触面521的前端和第二接触面313的后端接触，随着第一推杆520的伸展，锁栓310朝向左运动以使限位杆330脱离第一约束位置，随后第一驱动器510带动第一推杆520复位，锁栓310在弹性件320的作用下带动限位杆330向右运动到第二约束位置。通过第一接触面521和第二接触面313的设计，不需要复杂的传动机构即可实现动力的传递。
在本申请的一些实施例中，锁舌100设有限位位置，在锁栓310移动至锁舌100的限位位置时，锁栓310限制锁舌100活动，在锁栓310离开锁舌100的限位位置时，锁栓310非限制锁舌100活动。
具体地，在需要锁栓310进行锁定时，洗碗机发出信号，第一驱动器510便驱动锁栓310移动至锁舌100的限位位置，在不需要锁栓310进行锁定时，第一驱动器510便驱动锁栓310复位。可以理解的是，此处的限位位置即为锁舌100与锁栓310进行相互配合的结构，使得锁舌100发生移动时，锁栓310能阻碍锁舌100的移动，例如限位位置可以是卡槽结构、通孔结构等。
具体地，如图1和图3所示，锁舌100包括杆体110和位于杆体110末端的卡凸120，杆体110和卡凸120之间形成第一卡槽130和第二卡槽140，第一卡槽130构成锁舌100的限位位置。由图可知，锁舌100包括杆体110和位于杆体110末端的卡凸120，卡凸120的宽度略微大于杆体110的宽度，卡凸120与杆体110之间形成第一卡槽130和第二卡槽140，卡凸120朝向锁芯200形成有凸弧面121。第一卡槽130形成在锁舌100脱离锁芯200的方向上，第一卡槽130大致呈直角，当锁栓310在第一驱动器510的驱动下伸入第一卡槽130，锁栓310和卡槽在锁舌100脱离锁芯200的方向上形成面接触，且接触面垂直于锁舌100脱离锁芯200的方向，这样大大增强了锁栓310阻碍锁舌100的效果，有效防止了锁舌100的外力的作用下(用户拉动)强行与锁芯200分离。
在一些实施例中，如图14和图15所示，锁栓310设有第一导向面311，在锁栓310处于所述第一约束位置而锁舌100脱离锁芯200时，锁舌100与所述第一导向面311相抵接以驱动锁移动；或者，锁栓310设有第二导向面312，在锁栓310处于第一约束位置而锁舌100插入锁芯200时，锁舌100与第二导向面312相抵接以驱动锁栓310移动。具体地，存在着一些这样的情况，例如某些元器件出现故障使锁栓310持续处于第一约束位置，此时用户需要强行拉开门或关上门，或其它情况需要强行拉开门或关上门。因此，通过设置第一导向面311，第一导向面311呈倾斜面，即使此时锁栓310处于上锁状态，但当用户需要开门用力超过某个临界点时，锁舌100的限位位置将通过第一导向面311带动锁栓310移动，从而实现开门，此时锁栓310可由第一约束位置移动至第二约束位置，当然，这个临界点的所需的力要设置得比较大，既能实现用户误开门也能使得在某些特殊情况下能打开门。对于第二导向面312也是如此，第二导向面312呈倾斜面，即使此时锁栓310处于上锁状态，但当用户需要关门而用力超过某个临界点时，锁舌100的凸弧面121与第二导向面312接触，通过第二导向面312挤压锁栓310从而带动锁栓310移动，从而实现开门，此时锁栓310可由第一约束位置移动至第二约束位置。
如图1和图3所示，在本申请的一些实施例中，锁芯200设有转臂210，转臂210设有卡爪213、拨杆212和连杆211，卡爪213、拨杆212和连杆211相交设置且相交之处设有转动轴心，转臂210可绕转动轴心转动；
在锁舌100插入锁芯200的过程中，锁舌100作用于拨杆212而使转臂210转动，以让卡爪213锁定锁舌100；在锁舌100脱离锁芯200的过程中，锁舌100作用于卡爪213而使转臂210转动，以让卡爪213释放锁舌100；
拨杆212设有限位位置，在锁栓310移动至连杆211的限位位置时，锁栓310限制转臂210活动以限制锁芯200活动，在锁栓310离开连杆211的限位位置时，锁栓310非限制转臂210活动以非限制锁芯200活动。
具体地，卡爪213、拨杆212和连杆211一体成型构成转臂210，围绕着转动轴心可转动设置，连杆211的末端设置有压簧220，压簧220的其中一个延伸端插入连杆211的末端，与连杆211的末端可转动设置，压簧220的另一个延伸端插入到下文中提到的下壳体620上，与下壳体620可转动设置。在门体呈关闭状态时，转臂210位于第一位置，此时压簧220呈形变状态或呈非压缩状态，若压簧220呈形变状态(以压缩状态为例)，即压簧220具有对转臂210产生力而转臂210保持在第一位置。在门体打开时，锁舌100通过卡凸120对卡爪213产生力，继而整个转臂210跟随着锁舌100的移动而发生转动转动(顺时针)，此时压簧220在连杆211的作用下跟随转动(逆时针)且发生压缩直至最大值，随着锁舌100的移动与卡爪213分离，压簧220恢复形变，从而推动转臂210保持在第二位置。在门体关闭时，锁舌100通过卡凸120对拨杆212产生力，由于卡凸120的端面为凸弧面121，如此降低了和拨杆212的接触面积，有效降低了阻力，整个转臂210跟随着锁舌100的移动而发生转动(逆时针)，此时压簧220在连杆211211的作用下跟随转动(顺时针)且发生压缩直至最大值，随着锁舌100的移动到预定位置，卡爪213嵌入到第二卡槽140内，压簧220恢复形变，从而推动转臂210保持在第一位置。转臂210的转动平面和压簧220的转动平面共面或相互平行，有利于整个门锁往更薄的方向改进。
进一步地，如图1所示，在拨杆212的转动路径上设置有转杆230，在锁舌100和锁芯200锁定时，拨杆212逆时针转动而对转杆230产生动作，转杆230顺时针推动弹簧231压缩，转杆230与微 动开关350分离。在锁舌100和锁芯200脱离时，拨杆212顺时针转动，弹簧231推动转杆230逆时针转动，以使转杆230触碰微动开关350的按钮。通过如此设置，在锁舌100和锁芯200锁定或脱离时，洗碗机能生成相应的信息输出至显示屏上。
连杆211的限位位置与锁舌100的限位位置作用相类似，即通过阻碍连杆211的限位位置便能阻止转臂210的活动，从而阻止锁舌100的活动。如图1至图3所示，连杆211的末端构成锁芯200的限位位置，该末端至转动轴心的距离相当于一个较长的力臂，相当于利用杠杆作用大大提高了阻挡效果。
在本申请的一些实施例中，所述第一驱动件500用于在预设条件下驱动所述锁栓310。具体地，预设条件可以设置为预设温度，洗碗机在一个洗涤循环会先后经过预洗、漂洗、干燥，在预洗时通常会使用冷水或温水进行，而在漂洗会使用高温水进行，预设条件设计为漂洗阶段的温度值，洗碗机在运行到漂洗阶段时，其设定的洗涤时序会控制第一驱动件500驱动锁栓310进行上锁，如此即可防止用户误开门而造成伤害。可以理解的是，预设条件还可以设计成洗碗机的洗涤泵的工作与否，洗涤泵工作时水流会从喷臂射出，在洗涤泵工作时即控制第一驱动件500驱动锁栓310实现对锁舌100或锁芯200的限制，无论洗碗机处于什么阶段，均能防止用户误开门造成的伤害；还可以是，设置有微动开关340，当检测到锁舌100插入时即控制锁栓310进行上锁，预设条件即为锁舌100和锁芯200关闭。对于其他的一些设备，如洗衣机，可采用转速作为预设条件，对于烤箱，可采用温度作为预设条件。
进一步地，第一驱动件500的第一驱动器510为通电后执行相应动作的元器件，具体地，第一驱动器510为蜡马达。蜡马达是一种驱动装置，其包括热敏电阻，热敏电阻被安装在一个充有固体蜡的密封容器上。当固体蜡被通电的热敏电阻加热时，固体蜡熔化、膨胀，从而向外驱动活塞。当热敏电阻被断电时，液态蜡冷却，内部弹簧使活塞返回其初始位置。洗碗机在工作的过程中，当收到需要锁栓310上锁的信号时，第一驱动器510通电，从而驱动锁栓310移动，后第一驱动器510可以复位，锁栓310约束在第一约束位置，当收到需要锁栓310解锁的信号时，第一驱动器510再次通电，从而驱动锁栓310移动，后第一驱动器510可以复位，锁栓310约束在第二约束位置。
在本申请的一些实施例中，如图11所示，门锁还包括上壳体610和下壳体620，上壳体610与下壳体620连接以形成容置空间，锁芯200、锁栓310、第一驱动件500设于该容置空间。上壳体610作为盖体和下壳体620连接，下壳体620上设置有缺口可供锁舌100的进出。本实施例通过将上壳体610和下壳体620将锁芯200、锁栓310、第一驱动件500集合为一个整体部件，方便安装到洗碗机。
本申请还公开了另一种门锁，下文将详细介绍。
如图17至图20所示，门锁包括所述锁舌100、锁芯200和锁定件300。在一些实施例中，所述锁舌100可以设置在门体上，所述锁芯200则设置在机体，在另一些实施例中，所述锁舌100可以设置在机体上，所述锁芯200则设置在门体。所述锁舌100是一种和所述锁芯200相互配合实现锁定或释放的结构，它们可以在力的作用下分离或闭合，如用户拉动门体打开时，所述锁舌100和所述锁芯200分离，用户推动门体关闭时，所述锁舌100和所述锁芯200锁闭，所述锁舌100和所述锁芯200的具体的形式可以根据实际情况进行选择。在本实施例中，以所述锁舌100设置在门体、所述锁芯200设置在机体为例进行说明。
一般来说，所述锁舌100可采用金属材料制造而成，如通过铁、铝等铸造而成单个零部件，具有较高的强度，所述锁舌100通过螺纹紧固件固定在门体的顶部。门体具有内门体和外门体，内门体的顶部形成用于安装所述锁舌100的安装位，所述锁舌100可螺纹紧固于内门体上的安装位。所述锁舌100能跟随着门体的移动而移动，在门体需要关闭时，所述锁舌100随着门体而插入所述锁芯200内，从而被所述锁芯200锁紧，此时门体处于关闭状态；在门体需要打开时，所述锁舌100随着门体而脱离所述锁芯200，此时门体处于打开状态。正如此，通过拉动或推动门体实现门体的开闭，在一些情况下可能门体会被用户误操作而打开，因此通过设置所述锁定件300，该锁定件300能在洗碗机达到某种运行条件时自动限制所述锁舌100或所述锁芯200的活动，从而防止锁舌100和锁芯200的相分离。
具体地，当所述锁定件300限制所述锁舌100的活动时，所述锁舌100便不能随着门体的打开而打开，这里限制即为施加给所述锁舌100极大的阻碍，从而防止门体被强行拉开，或者说能大大增加门体被打开的阻力，以便让用户识别到此时是不能打开门体的，从而防止所述锁舌100和所述锁芯200 的分离导致的门体被打开。不同的所述锁舌100和所述锁芯200具体的结构不同，从而使得所述锁舌100和所述锁芯200的锁定或释放具有多种方式，但是所述锁舌100必定是要跟随着门体移动的，只要所述锁定件300能制约所述锁舌100跟随门体移动即可。
可以理解的是，在所述锁舌100插入所述锁芯200时，所述锁芯200要想完成对所述锁舌100的锁定，所述锁芯200必须要进行相应的活动才能锁定所述锁舌100，而对于所述锁舌100脱离所述锁芯200时也是如此，在所述锁舌100要脱离锁芯200时，锁芯200也需要作出相应的活动才能释放锁舌100，因此通过将所述锁定件300限制所述锁芯200的活动也能给所述锁舌100脱离所述锁芯200施加较大的阻碍，从而可以在需要锁定件300上锁时进行上锁，防止用户误开门。
由上可知，在所述锁定件300不工作时，所述锁舌100和所述锁芯200可正常实现门体的启闭，在所述锁定件300工作时，相当于在所述锁舌100和所述锁芯200所构成的锁结构上增设了一道机械防护装置，通过所述锁定件300对所述锁舌100或所述锁芯200进行约束，从而可以有效防止门体被强行拉开，或大大增加门体被拉开的阻力，避免出现危险。例如，在洗碗机处于高温漂洗的过程时，此时洗碗机的洗涤腔内的喷臂处于旋转喷射高温高压水流，若此时门体被强行拉开，则高温高压水流容易喷射出洗碗机外，对用户造成伤害，而通过所述锁定件300的作用，则有效避免了这种情况的发生。
如图17所示，在本申请的一些实施例中，所述锁舌100设有限位件，所述锁定件300包括第三驱动器370与锁栓310，所述锁栓310设置在所述第三驱动器370的驱动端；所述第三驱动器370用于驱动所述锁栓310移动至所述锁舌100的限位件，以限制所述锁舌100的活动。具体地，所述第三驱动器370是一种通电后执行相应动作的元器件，所述第三驱动器370可以采用多种形式，例如往复式驱动器、旋转式驱动器等，只要能实现驱动所述锁栓310移动即可，在本实施例中采用的是往复式驱动器，其能够带动所述锁栓310做往复运动，在需要所述锁定件300进行锁定时，洗碗机发出信号，所述第三驱动器370便驱动所述锁栓310移动至所述锁舌100的限位件，在不需要所述锁定件300进行锁定时，所述第三驱动器370便驱动所述锁栓310复位。可以理解的是，此处的限位件即为可以与所述锁栓310进行相互配合的结构，使得在所述锁舌100将要发生移动时，锁栓310能阻碍所述锁舌100的移动，例如锁舌的限位件可以是卡槽结构、通孔结构等。
具体地，如图17所示，在本申请的一些实施例中，所述限位件为卡凸120，所述锁舌100包括杆体110，卡凸120位于杆体100的末端，所述杆体110和所述卡凸120之间形成所述第一卡槽130。
由图可知，所述锁舌100包括所述杆体110所述卡凸120的宽度大于所述杆体110的宽度，卡凸120可以与杆体110一体成型，强度更高。所述卡凸120与所述杆体110之间形成所述第一卡槽130和所述第二卡槽140，第一卡槽130和第二卡槽140呈对称分布，所述卡凸120朝向所述锁芯200形成有所述凸弧面121。所述第一卡槽130形成在所述锁舌100脱离所述锁芯200的方向上，所述第一卡槽130大致呈直角，当所述锁栓310在所述第三驱动器370的驱动下伸入所述第一卡槽130，所述锁栓310和所述第一卡槽130在所述锁舌100脱离所述锁芯200的方向上形成面接触，且接触面垂直于所述锁舌100脱离所述锁芯200的方向，这样大大增强了所述锁栓310阻碍所述锁舌100的效果，有效防止了所述锁舌100的外力的作用下(用户拉动)强行与所述锁芯200分离。
进一步的，如图17至图19所示，所述锁芯200包括转臂210，所述转臂210设有卡爪213、拨杆212和连杆211，所述卡爪213、所述拨杆212和所述连杆211相交设置且相交之处设有转动轴心，所述转臂210可绕转动轴心转动；
在所述锁芯200锁定所述锁舌100的过程中，所述锁舌100作用于所述拨杆212而使所述转臂210转动，以让所述卡爪213锁定所述锁舌100；在所述锁芯200释放所述锁舌100的过程中，所述锁舌100作用于所述卡爪213而使所述转臂210转动，以让所述卡爪213释放所述锁舌100。
具体地，所述卡爪213、所述拨杆212和所述连杆211一体成型构成所述转臂210，围绕着转动轴心可转动设置，所述连杆211的末端设置有所述压簧220，所述压簧220的其中一个延伸端插入所述连杆211的末端，与所述连杆211的末端可转动设置，所述压簧220的另一个延伸端插入到下文中提到的下壳体620上，与所述下壳体620可转动设置。在门体呈关闭状态时，所述转臂210位于第一位置，此时所述压簧220呈形变状态或呈非压缩状态，若所述压簧220呈形变状态(以压缩状态为例)，即所述压簧220具有对所述转臂210产生力而所述转臂210保持在第一位置。在门体打开时，所述锁舌100 通过所述卡凸120对所述卡爪213产生力，继而整个所述转臂210跟随着所述锁舌100的移动而发生转动(顺时针)，此时所述压簧220在所述连杆211的作用下跟随转动(逆时针)且发生压缩直至最大值，随着所述锁舌100的移动与所述卡爪213分离，所述压簧220恢复形变，从而推动所述转臂210保持在第二位置。在门体关闭时，所述锁舌100通过所述卡凸120对所述拨杆212产生力，由于所述卡凸120的端面为所述凸弧面121，如此降低了和所述拨杆212的接触面积，有效降低了阻力，整个所述转臂210跟随着所述锁舌100的移动而发生转动(逆时针)，此时所述压簧220在所述连杆211的作用下跟随转动(顺时针)且发生压缩直至最大值，随着所述锁舌100的移动到预定位置，所述卡爪213嵌入到所述第二卡槽140内，所述压簧220恢复形变，从而推动所述转臂210保持在第一位置。所述转臂210的转动平面和所述压簧220的转动平面共面或相互平行，有利于整个门锁往更薄的方向改进。
如图17至图20所示，在本申请的一些实施例中，以所述锁舌100脱离和插入所述锁芯200的方向为第一方向(图示前后方向)，与第一方向垂直的为第二方向(图示左右方向)，所述锁栓310和所述第三驱动器370于第二方向依次排布于所述锁舌100的一侧。具体地，所述第三驱动器370是一种直线往复的驱动器，所述锁栓310和所述第三驱动器370依次分布，排列在所述锁舌100的一侧，如此能有效利用门锁的空间，并且通过如此设置，所述锁栓310的运动方向和所述锁舌100脱离所述锁芯200的方向是相互垂直的，所述锁舌100上的所述卡凸120对所述锁栓310产生的力垂直于所述锁栓310，能大大增强所述锁栓310对所述锁舌100的阻碍效果。进一步地，由于所述锁定件300和所述锁芯200的活动形式不一样，为了避免零部件的过于拥挤，所述锁定件300于第二方向设于所述锁舌100的左侧，所述锁芯200(所述转臂210)于第二方向设于所述锁舌100的右侧，如此，能有效降低涉及成本，避免所述锁定件300和所述转臂210之间的运动发生干涉，从而有效降低了门锁的体积，使得门锁更有利于小型化。
以上的一些实施例中介绍了所述锁定件300锁定所述锁舌100的情况，现介绍所述锁定件300锁定所述锁芯200的情况。如图21所示，限位件设置在锁芯200，所述锁定件300包括所述第三驱动器370和所述锁栓310，所述锁栓310设于所述第三驱动器370的驱动端；所述第三驱动器370用于驱动所述锁栓310移动至所述锁芯200的限位件，以限制所述锁芯200的活动。与前面的一些实施例不同的是，本实施例中所述锁定件300改为限制所述锁芯200的活动。可以理解的是，在所述锁舌100和所述锁芯200进行锁定或释放的过程中，随着所述锁舌100的和移动，所述锁芯200需要进行一定程度的相应活动，因此通过对所述锁芯200进行约束，限制其活动，如此便能阻止所述锁舌100的移动，从而防止门体被打开。
具体地，如图21至图24所示，所述锁芯200包括转臂210，所述转臂210具有卡爪213、拨杆212和连杆211，限位件设置在连杆211上，在门体关闭时，所述锁舌100通过对所述拨杆212产生力，从而使得整个所述转臂210转动，在门体开启时，所述锁舌100通过对所述卡爪213产生力，从而使得整个所述转臂210转动。在需要所述锁定件300进行锁定时，所述锁定件300动作对所述连杆211的限位件进行限制，便可对整个所述转臂210的转动产生制约。由于所述卡爪213和所述拨杆212均用于与所述锁舌100产生相应的动作，所述锁定件300对所述转臂210的限制为通过所述连杆211实现，避免了对所述卡爪213和所述拨杆212与所述锁舌100之间的相应动作产生干扰，更有利于零部件的排布。
进一步地，如图21至图24所示，限位件设于连杆211的末端，且限位件和连杆211一体成型。具体地，所述卡爪213、所述拨杆212和所述连杆211构成的所述转臂210围绕着转动轴心转动，所述连杆211的末端设置限位件，该末端至转动轴心的距离相当于一个较长的力臂，相当于利用杠杆作用大大提高了阻挡效果。具体地，如图21和图24所示，以所述锁舌100脱离和插入所述锁芯200的方向为第一方向(图示前后方向)，与所述第一方向垂直的为第二方向(图示左右方向)，所述转臂210、所述锁栓310和所述第三驱动器370于所述第二方向依次排布于所述锁舌100的一侧。如此设计使得所述转臂210、所述锁栓310和所述第三驱动器370三者的运动相互不干涉，有效利用了内部空间，降低了门锁的占用体积。
具体地，如图22至图24所示，所述连杆211的末端的限位件呈圆弧面，所述锁栓310的末端设有相对应的所述第二凹口360，当所述锁栓310移动到位时，所述连杆211的末端嵌入到所述第二凹口 360中，能有效防止所述连杆211挣脱。此外，所述锁栓310的结构整体上呈L型，更加适应所述第三驱动器370的位置设置，充分利用门锁的内部空间，避免第三驱动器370某些部分过于突出造成而占用外部空间。
为了使得锁舌100和锁芯200的锁定或释放生成相应的信息，在一些实施例中，如图17至19所示，门锁还包括微动开关350，微动开关350用于在转臂210转动时被触发。转臂210转动的过程可以直接触碰微动开关350，或者间接触碰微动开关350，例如门锁还包括杠杆230，杠杆230的一端用于与所述拨杆212连接，所述杠杆230的另一端用于触碰所述微动开关350的按钮。在锁舌100和锁芯20闭合时，转臂200逆时针转动，拨杆212带动杠杆230顺时针转动，弹簧231压缩，杠杆230和微动开关350分离。在锁舌100和锁芯200分离时，转臂200顺时针转动，拨杆212逐渐与杠杆230分离，杠杆230在弹簧231伸展的作用下逆时针转动与微动开关350相触碰。由以上实施例的描述可知，本申请中，通过在可锁定或释放的所述锁舌100和所述锁芯200所构成的基础上，通过增设机械锁止结构——所述锁定件300，该所述锁定件300能对所述锁舌100或所述锁芯200进行约束，从而避免所述锁舌100和所述锁芯200在锁定的状态下，避免外力强行分离，将此门锁应用到诸如洗碗机等家电设备时，能有效防止用户尤其是小孩误开门造成伤害的情况出现。
在本申请的一些实施例中，如图21至图24所示，所述门锁还包括所述第二驱动件700，所述第二驱动件700用于对所述转臂210产生力，以使所述转臂210转动以由所述第一位置切换至第二位置。具体地，通过所述第二驱动件700的设置，能在所述锁定件300处于非锁定状态时，实现所述锁舌100和所述锁芯200的自动分离。通过同一的所述转臂210实现所述锁定件300的锁定以及所述第二驱动件700的自动打开，大大增强了门锁的功能性，适用于更多不同的产品场景。以洗碗机为例，洗碗机在一个洗涤循环会先后经过预洗、漂洗、干燥，漂洗阶段通常是高温漂洗，漂洗阶段结束后需要对餐具进行干燥，漂洗阶段通过所述锁定件300进行上锁，干燥阶段通过所述第二驱动件700对所述转臂210产生力，所述转臂210继而转动而释放所述锁舌100，门体实现了自动打开的效果，由于漂洗阶段刚结束而餐具依然保持有较高的温度，在门体打开后，餐具上的水分便能在余温下蒸发，从而达到干燥的目的，而且可以使洗碗机的洗涤腔的高温高湿气流逸出，进一步的提高了干燥效果。
进一步地，如图24所示，所述第二驱动件700包括所述摆杆730，所述摆杆730可转动设置；以及所述第二驱动器710，所述第二驱动器710驱动所述摆杆730的一端(右端)以让所述摆杆730的另一端(左端)转动而动作于所述转臂210，以使所述转臂210转动以由所述第一位置切换至所述第二位置。具体地，所述摆杆730起到传递力的作用，通过设置所述摆杆730这个中间件，能将所述第二驱动器710的力进行传递，如此所述第二驱动器710可选用较为简单的往复式驱动器，降低了门锁的复杂度，也能充分地利用门锁的内部空间。
具体地，所述压簧220设于所述摆杆730的前述另一端(左端)，所述压簧220的其中一延伸端与所述转臂210转动连接，所述压簧220的另一延伸端插入所述转臂210中。如图21所示，所述转臂210具有所述连杆211，所述摆杆730的前述另一端(左端)设有所述安装柱731，所述压簧220套设在所述安装柱731上，或者所述压簧220与所述安装柱731粘接固定，所述连杆211的末端设有安装孔，所述压簧220的其中一延伸端插入安装孔且可转动，所述压簧220的另一延伸端插入所述摆杆730上。
工作过程如下，所述第二驱动器710可以直接驱动所述摆杆730，也可以间接驱动所述摆杆730，在本实施例中，通过设置所述第二推杆720实现力的传递，如此方便各元器件的排布。在门体处于关闭状态时，若要实现对门体的打开，所述第二驱动器710驱动所述第二推杆720移动，所述第二推杆720对所述摆杆730的右端产生力的作用使得所述摆杆730转动，所述摆杆730带动所述压簧220跟随转动，所述压簧220带动所述连杆211而使整个所述转臂210转动，在这一个过程中所述压簧220出现压缩，在所述压簧220压缩到最大值时，由于所述转臂210已经转动到一定程度与所述锁舌100分离，此时所述压簧220开始复位而对所述转臂210产生力，将所述转臂210保持在第二位置，此时所述第二驱动器710可断电，所述第二驱动器710带动所述第二推杆720复位。在门体关闭时，所述锁舌100推动所述拨杆212，整个所述转臂210跟随所述锁舌100的移动而转动(逆时针)，带动所述压簧220和所述摆杆730顺时针转动，此过程中所述压簧220压缩到最大值，在所述锁舌100达到预定位置时， 所述转臂210已转过一定程度，所述压簧220由压缩到最大值切换复位而对所述转臂210产生力，将所述转臂210保持在第一位置。
在本申请的一些实施例中，如图21和图22、图23所示，所述转臂210和所述锁定件300的所述锁栓310之间形成所述安装空间622，所述摆杆730位于所述安装空间622。具体地，由于所述转臂210设计为可转动设置，而所述锁栓310的活动的直线往复式，正是由于这两种结构的活动形式不一样，如此安排所述转臂210和所述锁定件300，在保证各部件正常工作的前提下，能提供充裕的空间给所述摆杆730，使得所述摆杆730控制所述压簧220的动作不受干扰。
在本申请的一些实施例中，如图17所示，门锁还包括所述上壳体610和所述下壳体620，所述上壳体610与所述下壳体620连接以形成容置空间，所述锁芯200与所述锁定件300设于所述容置空间；
所述上壳体610、所述下壳体620或所述上壳体610与所述下壳体620之间设有所述滑轨621，所述锁定件300的所述锁栓310可在所述锁定件300的所述第三驱动器370的作用下于所述滑轨621中往复运动。
具体地，所述锁定件300、所述第二驱动件700和所述锁芯200均安装到所述下壳体620相应的位置上，所述上壳体610作为盖体和所述下壳体620连接，所述下壳体620上设置有所述缺口623可供所述锁舌100的进出。所述滑轨621可以设置在所述上壳体610，或者设置在所述下壳体620，或者设置在所述上壳体610和所述下壳体620之间，对所述锁栓310起到一定的约束引导作用，防止所述锁栓310跑偏而且能在增强所述下壳体620的结构强度，增强所述锁栓310受到所述锁舌100作用力时的稳定性。本实施例通过将所述上壳体610和所述下壳体620将各部件集合为一个整体部件，方便门锁的安装。以洗碗机为例，洗碗机具有内胆，环绕内胆的开口设置有一圈加强筋，加强筋的作用在于加强整个内胆的结构强度，防止内胆发生变形，而加强筋一般设置有门锁的安装位置，将上壳体610和下壳体620组合成的门锁安装到加强筋上，继而用螺钉进行锁定，这样便能固定，方便安装。
在本申请的一些实施例中，所述锁定件300用于在预设条件下动作以限制所述锁芯200或所述锁舌100的活动。具体地，预设条件可以设置为预设温度，洗碗机在一个洗涤循环会先后经过预洗、漂洗、干燥，在预洗时通常会使用冷水或温水进行，而在漂洗会使用高温水进行，预设条件设计为漂洗阶段的温度值，洗碗机在运行到漂洗阶段时，其设定的洗涤时序会控制所述锁定件300进行上锁，如此即可防止用户误开门而造成伤害。可以理解的是，预设条件还可以设计成洗碗机的洗涤泵的工作与否，洗涤泵工作时水流会从喷臂射出，在洗涤泵工作时即控制所述锁定件300实现对锁舌或锁芯进行限制，无论洗碗机处于什么阶段，均能防止用户误开门造成的伤害；还可以是，设置有微动开关，当检测到所述锁舌100插入时即控制所述锁定件300进行上锁，预设条件即为所述锁舌100和所述锁芯200关闭。对于其他的一些设备，如洗衣机，可采用转速作为预设条件，对于烤箱，可采用温度作为预设条件。
在本申请的一些实施例中，所述锁定件300的所述第三驱动器370和所述第二驱动件700的所述第二驱动器710为通电后执行相应动作的元器件，具体地，所述第三驱动器370和所述第二驱动器710为蜡马达。蜡马达是一种驱动装置，其包括热敏电阻，热敏电阻被安装在一个充有固体蜡的密封容器上。当固体蜡被通电的热敏电阻加热时，固体蜡熔化、膨胀，从而向外驱动活塞。当热敏电阻被断电时，液态蜡冷却，内部弹簧使活塞返回其初始位置。洗碗机在工作的过程中，当收到需要所述锁定件300上锁的信号时，所述第三驱动器370通电，从而驱动所述锁栓310移动，当收到需要所述锁定件300解锁的信号时，第一驱动断电，从而驱动所述锁栓310复位。除此之外，正是由于采用的是蜡马达，当所述锁定件300处于上锁的状态而突然出现整机断电时，所述锁栓310可复位，用户可正常拉开门体。对于所述第二驱动器710，当收到需要自动打开门体的信号时，所述第二驱动器710通电，从而驱动所述第二推杆720移动，而后所述第二驱动器710断电，驱动所述第二推杆720复位，此时所述第二推杆720和所述摆杆730分离。
由上可知，本申请公开了一种门锁，门锁可以应用于洗碗机等设备中，该门锁具有锁舌100和锁芯200，锁舌100和锁芯200构成了门锁结构，即通过锁舌100和锁芯200的闭合或释放，即可实现门体的关闭和打开，可以理解的是，门体的关闭和打开是基于外力的情况下，例如用户推动门体关闭，此时锁舌100和锁芯200即实现闭合，用户推动门体打开，此时锁芯200释放锁舌100，锁芯200和锁舌100相互分离。在此基础上增加了一道机械防护装置锁定件300，锁定件是一种物理防护结构，能用 于限制锁芯200或锁舌100的活动，如此，在需要锁定件300上锁时洗碗机即可控制锁定件300进行锁定，能有效防止门体被打开。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
