下面参考附图描述根据本申请第一方面实施例的微波炉1000的联锁装置100和具有其的微波炉1000。
参照图1-图10所示，根据本申请第一方面实施例的微波炉1000可以包括机体、门体200和根据本申请实施例的微波炉1000的联锁装置100。其中，门体200安装于机体，例如可转动地安装于机体，以实现机体的盛放腔的打开和关闭，实现门体200的开门状态和关门状态的切换。联锁装置100可以根据门体200的状态切换实现相应功能。
根据本申请实施例的微波炉1000的联锁装置100可以包括：第一门勾11、联锁支架20、第一杠杆30和第二杠杆40。
具体而言，第一门勾11可以安装于门体200，以随门体200的开关门动作而相对于机体移动。联锁支架20安装于机体，以使第一门勾11相对于机体移动的过程中，能够与联锁支架20以及联锁支架20上的部件相配合。
具体地，联锁支架20上设有三个开关件，分别为监控开关201、第一微动开关202和第二微动开关203。可选地，监控开关可以为微动开关。其中，监控开关201、第一微动开关202和第二微动开关203被依次触发时，判断门体200关闭，微波炉1000能够正常通电和工作。
在相关技术中，微波炉采用的微动开关布局形式都是通过活动门勾的上门勾在关门的时候控制初级微动开关，下门勾间接的控制次级微动开关和监控微动开关。然而，上述触发微动开关的方式，在关门过程中微动开关的触发顺序以发生混乱，导致微波炉存在安全隐患或影响使用寿命。
而在本申请的实施例中，如图1-图10所示，第一杠杆30可转动地安装于联锁支架20，且第二杠杆40可转动地安装 于联锁支架20。在微波炉1000关门过程中，第一门勾11相对于联锁支架20移动，并依次驱动第一杠杆30和第二杠杆40转动，以使第一杠杆30触发监控开关201后，第二杠杆40依次触发第一微动开关202和第二微动开关203。
由此，通过同一个门勾的驱动(即通过第一门勾11的驱动)，以及两个杠杆(即第一杠杆30和第二杠杆40)的有序传动，实现监控开关201、第一微动开关202和第二微动开关203的依次被触发，避免出现多个开关件触发顺序混乱的问题，保证门体200开闭状态检测准确，并且避免微波炉1000的电路损坏甚至发生安全事故，有利于提高微波炉1000的使用寿命。
举例而言，门体200绕竖直延伸的旋转轴线可转动地安装于机体，关门过程中，门体200转动使第一门勾11大体沿如图1所示的前后方向向后相对于联锁支架20移动。移动过程中，第一门勾11首先与联锁支架20上的第一杠杆30接触并驱动第一杠杆30沿第一方向(如图1所示的逆时针方向)转动，转动至预设角度时第一杠杆30触发监控开关201。然后第一门勾11与第二杠杆40接触并驱动第二杠杆40沿第二方向(如图1所示的顺时针方向)转动，转动至第一预设角度时触发第一微动开关202，继续转动至第二预设角度时触发第二微动开关203。由此，实现监控开关201、第一微动开关202和第二微动开关203的依次有序触发。
需要说明的是，第一杠杆30和第二杠杆40整个转动过程中，可以完全在第一门勾11驱动下转动，也可以由第一门勾11提供开始转动的初始作用力，然后在其他结构的驱动下转动，这都在本申请的保护范围之内。
此外，在一些实施例中，微波炉1000的门体200还可以包括第二门勾12，例如图1-图10所示，第一门勾11为下门勾，第二门勾12为上门勾，下门勾设于上门勾的下侧。当然还可以包括第三门勾或者更多门勾等，多个门勾沿竖向间隔分布。在包括多个门勾的实施例中，通过第一门勾11与两个杠杆配合间接触发三个开关件，保证了三个开关件开关的有序性。
其中，第一门勾11可以为固定式门勾，即相对于门体200固定，以使第一门勾11驱动第一杠杆30和第二杠杆40转动的过程中自身位置和结构稳定，避免因第一门勾11的位置改变而影响微动开关的有序触发；第二门勾12和第三门勾等其他门勾可以为固定式门勾，也可以为活动式门勾，例如可以为可转动或者可移动地安装于门体200的门勾。
根据本申请实施例的微波炉1000的联锁装置100，通过第一门勾11的驱动以及第一杠杆30和第二杠杆40杠杆的有序传动，实现监控开关201、第一微动开关202和第二微动开关203依次被触发，避免出现多个开关件触发顺序混乱的问题，保证门体200开闭状态检测准确，并且避免微波炉1000的电路损坏甚至发生安全事故，有利于提高微波炉1000的使用寿命。
由于根据本申请实施例的微波炉1000的联锁装置100具有上述有益的技术效果，因此根据本申请实施例的微波炉1000，通过第一门勾11的驱动以及第一杠杆30和第二杠杆40杠杆的有序传动，实现监控开关201、第一微动开关202和第二微动开关203依次被触发，避免出现多个开关件触发顺序混乱的问题，保证门体200开闭状态检测准确，并且避免微波炉1000的电路损坏甚至发生安全事故，有利于提高微波炉1000的使用寿命。
根据本申请的一些实施例，如图1-图10所示，第一杠杆30的转轴设于第二杠杆40的转轴的靠近第一门勾11的一侧，例如图3和图8所示，第一杠杆30的转轴位于第二杠杆40的转轴的前侧，第一门勾11设于第一杠杆30的转轴的前侧，使第一门勾11在关门过程中向后移动，能够先与第一杠杆30接触，再与第二杠杆40接触，避免开关件触发紊乱。
根据本申请的一些实施例，继续参照图1-图10所示，第一杠杆30的转轴和第二杠杆40的转轴分别位于第一门勾11垂直于关门方向的两侧。例如图3和图8所示，第一杠杆30的转轴位于第一门勾11的上侧，第二杠杆40的转轴位于第一门勾11的下侧。上述排布方式使第一杠杆30和第二杠杆40的布置以及转动互不干涉，且在关门方向上(如前后方向上)第一杠杆30和第二杠杆40的排布更紧凑，第一门勾11的长度无需设置过长即可与第一杠杆30和第二杠杆40接触传动，联锁装置100的结构更紧凑。
下面结合附图描述根据本申请一些实施例的第一杠杆30的具体结构。
在本申请的一些实施例中，如图14-图16所示，第一杠杆30可以包括第一驱动臂31，第一驱动臂31设有第一驱动部33，第一驱动部33用于触发监控开关201。如图6-图10所示，在关门过程中，第一门勾11可以与第一驱动臂31相抵，以驱动第一驱动臂31绕第一杠杆30的转动轴线沿第一方向转动，从而带动第一驱动部33转动，使第一驱动部33能够转动至触发监控开关201的位置，使监控开关201打开。
需要说明的是，第一驱动部33在第一驱动臂31上的设置位置可以根据空间布置等实际情况灵活设置。例如，在第一驱动臂31的长度方向上，第一驱动部33可以设于第一驱动臂31的中部或者端部等任意位置。
在一些实施例中，第一驱动部33可以为设于第一驱动臂31沿轴向一侧的凸起，使第一驱动部33与监控开关201配合过程中，不受第一驱动臂31的干扰，避免第一驱动臂31误触监控开关201的风险。
在本申请的一些实施例中，如图14-图16所示，第一杠杆30还可以包括第二驱动臂32，第二驱动臂32位于第一驱动臂31靠近第一门勾11的一侧，换言之，第一驱动臂31位于第二驱动臂32沿第一方向的超前侧。
在关门过程中，第一门勾11能够伸至第一驱动臂31和第二驱动臂32之间，以使第一门勾11能够与第一驱动臂31相抵并驱动第一杠杆30开始沿第一方向转动。而在开门过程中，第一门勾11能够与第二驱动臂32相抵，以驱动第一杠杆30沿第二方向转动，第二方向与第一方向相反，使第一杠杆30能够与监控开关201脱离配合，监控开关201能够关闭。
由此，第一门勾11能够用于驱动第一杠杆30沿两个方向转动，以实现触发监控开关201和复位，有利于简化联锁装置100的结构。当然，驱动第一杠杆30复位的结构包括但不限于第二驱动臂32与第一门勾11配合，例如，在另一些实施例中，还可以设有弹簧等复位件，以在第一门勾11沿开门方向移动后能驱动第一杠杆30沿第二方向转动复位。
根据本申请的一些实施例，如图1-图10所示，联锁装置100还可以包括弹性件34，弹性件34连接联锁支架20和第一杠杆30。例如弹性件34可以为螺旋弹簧，螺旋弹簧可以为一个或者多个。举例而言，在图1-图10所示的示例中，弹性件34为拉簧，且为两个，如图15和图16所示，第一杠杆30设有连接部35，连接部35为设于第一杠杆30背向第一驱动部33的侧面的凸起。每个拉簧的一端与联锁支架20连接，另一端均与连接部35连接，且两个拉簧的一端间隔开一定距离。
此外，弹性件34具有第一驱动状态。在第一驱动状态，弹性件34向第一杠杆30施加沿第一方向转动的驱动力，以使第二驱动臂32带动第一门勾11沿关门方向移动。
具体地，如图6-图10所示，在关门过程中，第一门勾11沿关门方向移动，移动至第一驱动臂31和第二驱动臂32之间并与第一驱动臂31相抵，以驱动第一杠杆30开始沿第一方向转动；在第一杠杆30沿第一方向开始转动时或转动较小角度后，弹性件34处于第一驱动状态以自动驱动第一杠杆30沿第一方向转动，使第二驱动臂32带动第一门勾11继续沿关门方向移动，实现自动关门作用。此时，即使用户撤销对门体200的关门作用力，也能保证门体200关闭到位，保证第一门勾11能够沿关门方向移动至三个开关件均被触发。一方面使用户操作省力、方便，另一方面可以避免出现关门不到位的问题。
在一些实施例中，如图1-图5所示，弹性件34具有第二驱动状态。在第二驱动状态，弹性件34向第一杠杆30施加沿第二方向转动的驱动力。在关门过程中，第一门勾11能够与第一驱动臂31相抵，以使弹性件34由第二驱动状态切换至第一驱动状态。
具体地，在开门状态下，在弹性件34的作用下，第一杠杆30能够保持在所需位置，一方面避免第一杠杆30未受第一门勾11作用的情况下沿第一方向转动而误触发监控开关201，另一方面，可以保证第一门勾11关门过程中能够顺利移动至第一驱动臂31和第二驱动臂32之间，避免第一杠杆30转动而影响第一门勾11与第一杠杆30配合。并且通过第一门勾11与第一驱动臂31相抵驱动第一杠杆30沿第一方向转动，使弹性件34随第一杠杆30的转动及时切换驱动状态，保证弹性件34能够及时起到驱动关门作用。
在关门状态下，弹性件34处于第一驱动状态，使第一杠杆30能够通过第二驱动臂32与第一门勾11相抵，保证门体200保持在关门状态。在需要开门时，用户控制第一门勾11沿开门方向移动，并与第二驱动臂32相抵，以使第一杠杆30沿第二方向转动。当第一杠杆30转动至一定角度时，弹性件34由第一驱动状态切换至第二驱动状态，以使弹性件34能够驱动第一杠杆30沿第二方向转动以及时解除对第一门勾11的阻力，使门体200能够轻松打开。
在本申请的一些实施例中，如图9、图14-图16所示，第二驱动臂32的长度可以小于第一驱动臂31的长度，以使在关门过程中，第一门勾11更易于移动至第一驱动臂31和第二驱动臂32之间，避免第二驱动臂32对第一门勾11的移动造成干涉。
在本申请的一些实施例中，如图9、图14-图16所示，在第一杠杆30的轴向上，第二驱动臂32的厚度小于第一驱动臂31的厚度，厚度差使第二驱动臂32与联锁支架20之间的间隙大于第一驱动臂31与联锁支架20之间的间隙。关门过程中，即使第二驱动臂32对第一门勾11沿关门方向的移动造成一定干扰，也易于通过第二驱动臂32或第一门勾11变形使第一门勾11移动至第一驱动臂31和第二驱动臂32之间，而第一门勾11与第一驱动臂31则不易变形导致第一门勾11移动至第一驱动臂31板远离第二驱动臂32的一侧，保证了第一门勾11与第一杠杆30配合工作的稳定性。
此外在一些具体实施例中，如图15和图16所示，在第一杠杆30的轴向上，第二驱动臂32的一侧表面设有减薄区域39，以使第一杠杆30安装于联锁支架20时，第二驱动臂32设有减薄区域39处能够与联锁支架20形成一定间隙。在第一杠杆30被误触导致沿第一方向转动至触发监控开关201的位置时，可以通过关门使第一门勾11由该间隙处强行穿过并移动至第一驱动臂31和第二驱动臂32之间，然后可以通过开门动作使第一门勾11带动第一杠杆30沿第二方向转动复位。
例如如图15和图16所示，联锁支架20包括支架本体22和盖体23，第一杠杆30安装于支架本体22和盖体23之间 内，减薄区域39可以为设于第二驱动臂32朝向支架本体22一侧的缺口槽，使第二驱动臂32与支架本体22之间形成上述间隙。
此外，第一门勾11的厚度可以沿关门方向递减，使第一门勾11如图1所示的后端厚度较小，前端厚度较大。在第一杠杆30误触发监控开关201的状态下，第一门勾11的前厚后薄的结构使第一门勾11更易于由减薄区域39移动至第一驱动臂31和第二驱动臂32之间，解决非正常触发问题更容易。
根据本申请的一些实施例，如图3和图8所示，联锁支架20可以设有第一限位部21。在关门状态下，第一限位部21能够与第一杠杆30相抵，以阻止第一杠杆30沿第一方向转动。换言之，第一限位部21能够限制第一杠杆30沿第一方向转动的极限位置，避免第一杠杆30转动角度过大而对监控开关201或第一门勾11造成损坏。
例如，在包括弹性件34的实施例中，弹性件34驱动第一杠杆30沿第一方向转动，以带动第一门勾11沿关门方向移动，实现自动关门动作；当转动至第一杠杆30与第一限位部21相抵时，第一限位部21的限位作用使第一杠杆30受力平衡，而不继续在弹性件34的驱动下转动，第一杠杆30能够保持在与第一门勾11稳定配合、使门体200保持关门状态的位置。
根据本申请的一些实施例，如图3和图8所示，联锁装置100还可以包括缓冲关门组件50。缓冲关门组件50连接联锁支架20和第一杠杆30，例如与第一杠杆30的第一驱动臂31相连。
在关门过程中，缓冲关门组件50用于向第一杠杆30施加与第一方向相反的缓冲力，以实现关门缓冲作用，避免关门过程中门体200与机体发生剧烈碰撞，也有利于降低关门噪音。
本申请对缓冲关门组件50的具体结构不做特殊限制，只需要满足能够起到缓冲关门作用即可。例如，缓冲关门组件50可以包括阻尼器、弹片或者压簧等。
举例而言，在一些具体实施例中，如图3-图4和图8-图9所示，缓冲关门组件50包括缓冲件51和连接件52。其中，缓冲件51的一端与联锁支架20可转动连接，连接件52分别与缓冲件51的另一端和第一驱动臂31可转动连接，以使第一杠杆30转动过程中，缓冲件51能够起到缓冲作用，而可转动连接结构则使可以适应第一杠杆30的转动，避免发生卡死。
此外，继续参照图3-图4和图8-图9所示，第一驱动臂31具有驱动面36，连接件52可转动地安装于第一驱动臂31，且如图4所示在开门状态下连接件52与驱动面36呈预设角度，缓冲件51的另一端与连接件52可转动连接。在关门过程中，第一杠杆30沿第一方向转动预设角度后，驱动面36能够与连接件52相抵，以带动连接件52转动。
由于开门状态下，连接件52与驱动面36之间呈预设角度布置，使第一门勾11刚与第一杠杆30接触并驱动第一杠杆30沿第一方向转动时，缓冲件51不会向第一杠杆30施加缓冲力，使第一门勾11驱动第一杠杆30转动更容易。
在一些具体实施例中，如图3-图4和图8-图9所示，第一驱动臂31朝向缓冲关门组件50的一侧设有凹槽37，凹槽37的底壁面形成为驱动面36，凹槽37的其中一个侧面与连接件52孔轴连接，凹槽37的其中另一个侧面设有与驱动面36间隔开一定距离的弯勾38。缓冲件51为阻尼器，阻尼器由凹槽37的槽口与连接件52孔轴连接。联锁装置100还包括与第一杠杆30相连的弹性件34。
在开门状态下，弹性件34向第一杠杆30施加沿第二方向转动的驱动力，使第一门勾11能够顺利移动至与第一驱动臂31相抵，此时连接件52与驱动面36呈预设角度，使阻尼器不产生缓冲力。在关门过程中，第一门勾11与第一驱动臂31接触并驱动第一杠杆30沿第一方向转动，由于阻尼器无缓冲力，使第一门勾11驱动第一杠杆30仅需克服弹性件34的驱动力，阻力更小；当转动至连接件52与驱动面36相抵时，弹性件34切换状态至向第一杠杆30施加沿第一方向转动的驱动力，以主动驱动第一杠杆30转动、第一门勾11移动以及门体200关闭，此时阻尼器产生缓冲力，以降低关门噪音。在开门过程中，第一门勾11拉动第一杠杆30沿第二方向转动，连接件52相对于第一驱动臂31转动，使连接件52与驱动面36之间呈一定夹角，弯钩与连接件52相抵，以防止夹角过大、防止连接件52由凹槽37脱出，保证连接件52与第一杠杆30稳定连接。
举例而言，在另一些具体实施例中，缓冲关门组件50可以包括缓冲件51，缓冲件51为弹片或压簧，缓冲关门组件50形成为缓冲储能组件。具体地，弹片的一端与联锁支架20相连，第一杠杆30与弹片的另一端相抵，并且弹片可以发生弹性变形，以蓄能。
在关门过程中，第一杠杆30沿第一方向转动并挤压弹片的另一端，使弹片弯曲程度增大并积蓄能量，起到缓冲作用和储能作用；在开门过程中，弹片可以释放所储蓄的能量，以向第一杠杆30施加沿第二方向转动的驱动力，使第一杠杆30能够推动第一门勾11和门体200向开门方向移动，起到助推开门的作用。在关门状态下，弹片作用在第一杠杆30上的驱动力的方向指向第一杠杆30的转动中心或者转动中心附近，此时弹片不提供第一杠杆30转动方向的分力或只提供较小 的分力，保证门体200能够被紧紧关上。
下面结合附图描述根据本申请一些实施例的第二杠杆40。
在本申请的一些实施例中，如图17-图18所示，第二杠杆40包括：第一转动臂41、第二转动臂42和第三转动臂43，第一转动臂41、第二转动臂42和第三转动臂43沿第二方向(如图3所示的顺时针方向)依次排布。如图1-图10所示，在关门过程中，第一门勾11能够与第一转动臂41相抵，以驱动第二杠杆40沿第二方向转动，从而带动第二转动臂42和第三转动臂43沿第二方向转动，第二转动臂42能够触发第一微动开关202，第三转动臂43能够触发第二微动开关203，实现一个杠杆有序驱动两个微动开关打开。
在一些实施例中，如图17-图18所示，第一转动臂41、第二转动臂42和第三转动臂43中的至少两个沿第二杠杆40的轴向错开，以使第一转动臂41、第二转动臂42和第三转动臂43沿第二方向的夹角较小也不易产生位置干涉，有利于使联锁装置100在第一门勾11移动方向上的结构更紧凑。
举例而言，如图17和图18所示，在第二杠杆40的轴向上，第一转动臂41和第三转动臂43位于同一位置，第二转动臂42与其他两个转动臂错开，使三个转动臂在轴向上呈两层分布，对应的第一微动开关202和第二微动开关203能够沿第二杠杆40的轴向呈两层布置，而第一门勾11可以由第一转动臂41背向第三转动臂43的一侧驱动第二杠杆40，由此避免第一门勾11、第一微动开关202和第二微动开关203相干涉。
在一些实施例中，第二转动臂42上可以设有第二驱动部44a，使第二转动臂42与第一微动开关202在轴向上也能够至少部分错开，以满足空间布置需求。
根据本申请的一些实施例，如图11-图13所示，联锁支架20可以包括支架本体22和盖体23，盖体23盖设于支架本体22，以使盖体23与支架本体22配合可以限定出安装空间204，第一杠杆30和第二杠杆40安装于安装空间204，以对第一杠杆30和第二杠杆40进行限位，保证两个杠杆能稳定转动，且不易被其他结构干涉或触碰而影响正常工作。
如图6-图10所示，第一门勾11在关门过程中，可以伸入安装空间204内，以与第一杠杆30和第二杠杆40相接触，安装空间204还可以对第一门勾11与杠杆的配合结构进行遮挡保护，保证驱动的顺畅进行，同时还可以对第一门勾11起到导向作用，保证第一门勾11能够准确与第一杠杆30和第二杠杆40接触。
在一些具体实施例中，如图12和图13所示，支架本体22可以设有第一安装柱222和第二安装柱223，第一杠杆30套设于第一安装柱222，第二杠杆40套设于第二安装柱223。并且，第一安装柱222和第二安装柱223的端部均插设于盖体23，以通过与盖体23配合对支架本体22和盖体23进行限位，避免盖体23与支架本体22错位或变形而影响触发开关件。
此外，在一些实施例中，如图1-图5和图11-图13所示，监控开关201设于盖体23的背向支架本体22的一侧，盖体23设有第一通孔231，第一杠杆30设有第一驱动部33，第一驱动部33可以由第一通孔231穿过，以伸出至盖体23背向支架本体22的一侧。在第一杠杆30转动过程中，第一驱动部33在第一通孔231内随之转动，以便于触发监控开关201。监控开关201可以设于安装空间204外，以避免与安装空间204内的部件产生位置干涉，如避免与缓冲关门组件50干涉，位置排布更合理。
继续参照图1-图5和图11-图13所示，第一微动开关202设于盖体23的背向支架本体22的一侧，第二微动开关203设于安装空间204。盖体23还可以具有第二通孔232，第二杠杆40设有第二驱动部44a，第二驱动部44a可以由第二通孔232穿过，以伸出至盖体23背向支架本体22的一侧。在第二杠杆40转动过程中，第二驱动部44a在第二通孔232内随之转动，以便于触发位于安装空间204外的第一微动开关202。而第二杠杆40位于安装空间204内的部分可以触发位于安装空间204内的第二微动开关203。第一微动开关202和第二微动开关203位于盖体23的不同侧，使二者不会产生干涉。例如，第一微动开关202和第二微动开关203沿第二杠杆40的轴向的投影可以至少部分重合，以使两个微动开关的排布更紧凑，第二杠杆40依次触发两个微动开关也更快捷。
下面参考附图详细描述根据本申请的一个具体实施例的微波炉1000，值得理解的是，下述描述只是示例性说明，而不能理解为对申请的限制。
如图1-图18所示，根据本申请实施例的微波炉1000包括门体200、机体和联锁装置100。联锁装置100包括第一门勾11、第二门勾12、联锁支架20、第一杠杆30、第二杠杆40、监控开关201、第一微动开关202、第二微动开关203、弹性件34、缓冲关门组件50、驱动件53和斜块54。
其中，门体200绕竖直轴线可转动地安装于机体，第一门勾11和第二门勾12固设于门体200，且第二门勾12位于第一门勾11上方。联锁支架20安装于机体，且包括支架本体22和盖体23，以限定出安装空间204。第一杠杆30和第二杠杆40可转动地安装于安装空间204，第一杠杆30包括第一驱动臂31、第二驱动臂32和第一驱动部33，第一驱动部33穿 过盖体23的第一通孔231；第二杠杆40包括第一转动臂41、第二转动臂42、第三转动臂43和第二驱动部44a，第二驱动部44a穿过盖体23的第二通孔232。第二微动开关203设于安装空间204内，监控开关201和第一微动开关202设于盖体23背向支架本体22的一侧。支架本体22设有第三通孔221，弹性件34设于支架本体22背向盖体23的一侧，且第一杠杆30的连接部35穿过第三通孔221以与弹性件34相连。
此外，斜块54可竖向移动地安装于支架本体22，驱动件53两端分别与斜块54和支架本体22相抵，以向斜块54施加向上的驱动力。
如图1-图5所示，在开门状态下，第一门勾11和第二门勾12与机体分离。驱动件53驱动斜块54位于高位。第一杠杆30在弹性件34的拉力作用下沿顺时针方向转动至与支架本体22的边沿相抵的极限位置，且与监控开关201脱离配合；第二杠杆40处于与第一微动开关202和第二微动开关203分离的位置。
在关门过程中，推动门体200，使第一门勾11和第二门勾12沿关门方向移动，即向后移动。第一门勾11的后端伸至第一驱动臂31和第二驱动臂32之间，并与第一驱动臂31相抵，以推动第一杠杆30沿逆时针方向转动；第一杠杆30转动预设角度时，弹性件34的拉力方向切换至驱动第一杠杆30沿逆时针方向转动，以使第一杠杆30的第二驱动臂32自动拉动第一门勾11向后移动，且连接件52与驱动面36接触，驱动面36驱动连接件52运动，缓冲件51起到缓冲作用；第一杠杆30转动使第一驱动部33触发监控开关201；然后第一门勾11移动至与第二杠杆40接触时，驱动第二杠杆40沿顺时针方向转动，第二杠杆40的第二驱动部44a和第三转动臂43依次触发第一微动开关202和第二微动开关203。关门过程中，第二门勾12与斜块54相抵，斜块54压缩驱动件53使第二门勾12的勾部移动至斜块54的后侧，实现斜块54对第二门勾12的限位，以保持门体200关闭。
如图6-图10所示，当第一杠杆30转动至与第一限位部21相抵时停止转动，第二杠杆40触发第二微动开关203后停止转动。此时，在弹性件34的拉力作用下，第一杠杆30的第二驱动臂32止挡第一门勾11，进而使门体200保持在关门状态，第一杠杆30和第二杠杆40保持在使监控开关201、第一微动开关202和第二微动开关203导通的位置。
在开门过程中，门体200反向转动以打开，使第一门勾11向前移动。移动过程中，首先撤销对第二杠杆40的止抵力，第二杠杆40在第一微动开关202和第二微动开关203的反弹力作用下逆时针转动，以解除对第一微动开关202和第二微动开关203的触发；第一门勾11移动过程中还与第二驱动臂32相抵，以带动第一杠杆30克服弹性件34弹力并顺时针转动，使第一驱动部33解除对监控开关201的触发；当转动至弹性件34的拉力方向切换至驱动第一杠杆30沿顺时针方向转动时，在弹性件34的驱动下，第一杠杆30自动复位至与支架本体22的边沿相抵的位置，并停留在该位置，并且第一杠杆30可以驱动第一门勾11向前移动，以使门体200弹开。在开门过程中，第二门勾12再次与斜块54相抵，斜块54压缩驱动件53使第二门勾12的勾部移动至斜块54的前侧，接触斜块54对第二门勾12的限位，使门体200能够打开。
综上，通过第一门勾11与两个杠杆配合，分别触发三个开关件，开关件不直接与第一门勾11直接发生接触，且三个开关件能够按照监控开关201、第一微动开关202、第二微动开关203的顺序有序触发，保证了设备的安全性。
下面参考附图描述根据本申请第二方面实施例的微波炉1000的联锁装置100和具有联锁装置100的微波炉1000。
参照图19-图58所示，根据本申请第二方面实施例的微波炉1000可以包括机体、门体200和根据本申请实施例的微波炉1000的联锁装置100。其中，门体200安装于机体，例如可转动地安装于机体，以实现机体的盛放腔的打开和关闭，实现门体200的开门状态和关门状态的切换。联锁装置100可以根据门体200的状态切换实现相应功能。
根据本申请实施例的微波炉1000的联锁装置100可以包括：第一门勾11、联锁支架20和第二杠杆40。
具体而言，如图21、图41、图42、图57和图58所示，第一门勾11可以安装于门体200，以随门体200的开关门动作而相对于机体移动。联锁支架20安装于机体，以使第一门勾11相对于机体移动的过程中，能够与联锁支架20以及联锁支架20上的部件相配合。
具体地，联锁支架20上设有两个开关件，分别为第一微动开关202和第二微动开关203。其中，第一微动开关202和第二微动开关203需要被依次触发，以确保微波炉1000能够正常通电和工作。
在相关技术中，针对侧拉门微波炉的缓关门/软关门设计，采用了分体式门钩，利用卡扣、滑道、弹簧、阻尼器等实现缓关门过程，但该套缓关门***占用空间大，为保证与其他组件预留足够间隔，针对不同容积的机型，需要设计不同的大小比例的方案，通用性差，成本较高。
而在本申请的实施例中，如图21、图25和图36所示，第二杠杆40可转动地安装于联锁支架20，第二杠杆40可以包括设有第一配合部45的第一转动臂41、设有第二配合部44的第二转动臂42和设有第三配合部46的第三转动臂43。并且，第一配合部45、第二配合部44和第三配合部46绕第二杠杆40的转动轴线沿第一方向依次排布(如图21所示的顺时针方向)，一方面，有利于实现有序触发联锁支架20上的微动开关，避免触发顺序混乱。另一方面，有利于实现联锁支 架20上微动开关的合理布置，实现微波炉1000机体结构的紧凑性。
在微波炉1000关门过程中，如图19-图21所示，第一门勾11适于沿关门方向移动，以与第一配合部45相抵并驱动第二杠杆40沿第一方向转动，使第二配合部44触发第一微动开关202后第三配合部46触发第二微动开关203，可以实现有序触发第一微动开关202和第二微动开关203，用于检测门体200的开闭状态，确保微波炉1000能正常工作，避免触发顺序混乱，避免因微动开关的触发顺序混乱而使微波炉1000存在安全隐患。
需要说明的是，第一微动开关202和第二微动开关203上可以设有弹性片，第二配合部44与第三配合部46通过弹性片实现触发第一微动开关202和第二微动开关203。为确保触发顺序，应合理布置联锁支架20上的微动开关，第一微动开关202的弹性片和第二配合部44关于转动轴线的夹角应小于第二微动开关203的弹性片和第三配合部46关于转动轴线的夹角。
举例而言，如图19-图22所示，门体200绕竖直延伸的旋转轴线可转动地安装于机体，在关门过程中，门体200转动使第一门勾11大体沿图17所示的前后方向向后相对于联锁支架20移动。移动过程中，第一门勾11首先与第一配合部45接触并驱动第二杠杆40沿第一方向(如图17所示的顺时针方向)转动。第二杠杆40开始转动后，第二配合部44与第三配合部46同样沿第一方向转动相同的角度，通过联锁支架20上第一微动开关202与第二微动开关203的合理设置，第二杠杆40转动至第一预设角度时，第二配合部44可与第一微动开关202相接触，触发第一微动开关202。第二杠杆40继续转动至第二预设角度时，第三配合部46与第二微动开关203相接触，触发第二微动开关203。由此，实现第一微动开关202和第二微动开关203的有序触发。
相较于现有技术，在本申请中，通过第一配合部45、第二配合部44和第三配合部46沿第一方向依次排布，即第一配合部45、第二配合部44与第三配合部46在垂直于第二杠杆40轴线的截面的投影依次错开，可实现第一微动开关202和第二微动开关203的有序触发，无需增加第一转动臂41、第二转动臂42和第二转动臂42的臂长，从而减小了空间的占用，在确保有序触发微动开关的同时使联锁装置100的结构更加紧凑。并且，可以安装于容积较小的微波炉1000，通用性好，可以有效降低加工成本。
根据本申请实施例的微波炉1000的联锁装置100，通过第一配合部45、第二配合部44和第三配合部46绕第二杠杆40的转动轴线沿第一方向依次排布，第一配合部45被第一门勾11驱动后，第二配合部44和第三配合部46能依次触发对应的微动开关，确保了触发微动开关的有序性，避免了触发顺序混乱的问题，进而实现有效检测微波炉1000的开闭状态。并且，在能确保触发顺序的同时能有效减少转动臂的臂长，占用空间小，实现联锁装置100的结构紧凑性。由此，本申请的联锁装置100能适用于较小体积的微波炉1000，通用性强，可以有效降低生产成本。
此外，在一些实施例中，微波炉1000的门体200还可以包括第二门勾12，例如图19-图34所示，第一门勾11为下门勾，第二门勾12为上门勾，下门勾设于上门勾的下侧。当然还可以包括第三门勾或者更多门勾等，多个门勾沿竖向间隔分布。在包括多个门勾的实施例中，通过第一门勾11与第二杠杆40配合间接触发两个开关件，保证了两个开关件开关的有序性。
其中，第一门勾11可以为固定式门勾，即相对于门体200固定，以使第一门勾11驱动第二杠杆40转动的过程中自身位置和结构稳定，避免因第一门勾11的位置改变而影响微动开关的有序触发；第二门勾12和第三门勾等其他门勾可以为固定式门勾，也可以为活动式门勾，例如可以为可转动或者可移动地安装于门体200的门勾。
由于根据本申请实施例的微波炉1000的联锁装置100具有上述有益效果，因此根据本二申请实施例的微波炉1000，通过第一配合部45、第二配合部44和第三配合部46绕第二杠杆40的转动轴线沿第一方向依次排布，第一配合部45被第一门勾11驱动后，第二配合部44和第三配合部46能依次触发对应的微动开关，确保了触发微动开关的有序性，避免了触发顺序混乱的问题，进而实现有效检测微波炉1000的开闭状态。并且，在能确保触发顺序的同时能有效减少转动臂的臂长，占用空间小，实现联锁装置100的结构紧凑性。由此，本申请的联锁装置100能适用于较小体积的微波炉1000，通用性强，可以有效降低生产成本。
根据本申请的一些实施例，如图54和图55所示，第一配合部45和第二配合部44关于第二杠杆40轴线的夹角可以为α，第二配合部44和第三配合部46关于第二杠杆40轴线的夹角可以为β，其中，α＜β，一方面可以使微动开关有序触发的效果更好，另一方面可以通过减小第一配合部45与第二配合部44之间的夹角减少第二杠杆40对联锁装置100的空间占用。
具体地，通过第一配合部45与第二配合关于转动轴线之间存在α角，第二配合部44和第三配合部46之间存在β角，可以与联锁支架20上的微动开关配合实现有序触发的效果，避免触发顺序混乱而使微波炉1000存在安全隐患。在第二配合部44触发第一微动开关202后，第二杠杆40需要继续转动第二预设角度才能使第三配合部46触发到第二微动开关203， 而通过使β角大于α角，可以增大第二配合部44与第三配合部46在垂直于转动轴线平面上的距离，从而使第二预设角度越大，所能实现的有序触发微动开关的效果越好。
并且，通过α＜β，在第二配合部44和第三配合部46关于第二杠杆40轴线夹角一定的情况下，可以合理减小第一配合部45和第二配合部44关于第二杠杆40轴线的夹角，在能够确保有序触发微动开关的同时，能减小第二杠杆40在联锁装置100中所占用的空间资源，可以避免与联锁装置100中的其他部件发生位置干涉，有利于实现联锁装置100的结构紧凑性。
继续参照图54和图55，根据本申请的一些实施例，第一配合部45与第二杠杆40轴线的间距可以大于或等于第二配合部44与第二杠杆40轴线的间距，并且大于或等于第三配合部46与第二杠杆40轴线的间距，一方面，可以使第二杠杆40的占用空间小，有利于实现联锁装置100的结构紧凑性。另一方面，有利于快速触发联锁装置100，使微波炉1000快速进入工作状态。
具体而言，第一配合部45与第二杠杆40轴线的间距一定的情况下，可以合理减小第二配合部44与转动轴线之间的距离、第三配合部46与转动轴线之间的距离，使第二杠杆40所占用的空间资源更少，并且第二杠杆40的结构更加紧凑，进而可以使联锁装置100的结构更加紧凑。
并且，在第二配合部44与转动轴线之间的距离、第三配合部46与转动轴线之间的距离一定的情况下，可以合理增大第一配合部45与第二杠杆40轴线的间距，在关门过程中，第一门勾11沿关门方向移动时能更快地与第一配合部45相接触，以驱动第二杠杆40转动，进而第二配合部44、第三配合部46能更快地依次触发第一微动开关202和第二微动开关203，微波炉1000能快速进入工作状态。
根据本申请的一些实施例，如图35-图40和图45-图48所示，联锁支架20可以具有安装空间204，并且安装空间204的侧壁设有避让凹槽205，第一转动臂41可以位于避让凹槽205内，可以有效避免诸长条状物体或手指等沿关门方向***安装空间204后与第一转动臂41接触而使第二杠杆40转动，避免误触第一微动开关202和第二微动开关203。
并且，第一配合部45可以伸入安装空间204内，第一门勾11适于伸入安装空间204内，第一门勾11可以在安装空间204内沿关门方向移动，以关闭微波炉1000。在第一门勾11的移动过程中，第一门勾11可以与伸入安装空间204的第一配合部45相接触，以驱动第二杠杆40转动。
需要说明的是，由于第一配合部45可在第一转动臂41上根据实际需求灵活设置，可以通过改变第一配合部45在第一转动臂41上的位置，确保第一门勾11可以与第一配合部45相接触以驱动第二杠杆40转动，而其他的细条状物体手指不易在安装空间204内与第一配合部45发生接触，可以有效避免除第一门勾11以外的物体与第一配合部45接触进而误触微动开关，确保微波炉1000的使用安全性。
在一些实施例中，第一配合部45位于第一转动臂41顶端的侧面，一方面可以有效避免第一配合部45与安装空间204内的其他部件发生位置干涉，另一方面可以避免其他长条状的物体触第一配合部45而使第二杠杆40发生转动，微波炉1000的安全性能更好。
在联锁支架20包括支架本体22和盖体23的实施例中，盖体23盖设于支架本体22，以使盖体23与支架本体22配合可以限定出安装空间204。参照图19、图21、图24、图28、图30所示，第一微动开关202设于盖体23的背向支架本体22的一侧，第二微动开关203设于安装空间204。盖体23还可以具有第二通孔232，第二杠杆40的第二配合部44可以由第二通孔232穿过，以伸出至盖体23背向支架本体22的一侧。在第二杠杆40转动过程中，第二配合部44在第二通孔232内随之转动，以便于触发位于安装空间204外的第一微动开关202。而第三配合部46位于安装空间204内，可以触发位于安装空间204内的第二微动开关203。第一微动开关202和第二微动开关203位于盖体23的不同侧，使二者不会产生干涉。例如，第一微动开关202和第二微动开关203沿第二杠杆40的轴向的投影可以至少部分重合，以使两个微动开关的排布更紧凑，第二杠杆40依次触发两个微动开关也更快捷。
根据本申请的一些实施例，如图35-图40所示、图45-图48所示，联锁支架20可以包括第一挡板25，第一挡板25可以部分遮挡避让凹槽205与安装空间204的连通口，可以避免手指或其他物体触第一转动臂41而使第二杠杆40发生转动，同时第一挡板25还可以对第一转动臂41起到限位作用。
具体地，第一转动臂41在避让凹槽205内可能发生沿转动轴线方向发生位移，一方面不能满足转动杆杆稳定状态，另一方面如果第一转动臂41的部分或全部移动出避让凹槽205，手指或其他长条状物体在没有遮挡物的情况下依然可以通过第一转动臂41驱动第二杠杆40，依然存在通过误触使第二杠杆40转动的风险。而通过设置第一挡板25，第一挡板25部分遮挡避让凹槽205与安装空间204的连通口，可以使第一转动臂41稳定位于避让凹槽205内而不能移动至安装空间204，避免手指等误触第一转动臂41。同时，第一挡板25还可以对第一转动臂41起到限定和导向的作用。在第一门勾11 与第一配合部45相抵驱动第二杠杆40转动时，第一挡板25可以与联锁支架20朝向第一转动臂41的侧面形配合形成配合槽，第一转动臂41可以在配合槽内平稳转动，避免第二配合部44、第三配合部46与对应设置的微动开关发生错位而不能准确触发，避免微动开关不能准确触发而影响微波炉1000的工作状态。
需要说明的是，第一挡板25部分遮挡避让凹槽205与安装空间204的连通口，而非全部遮挡。若第一挡板25完全遮挡住连通口，第一转动臂41无法通过连通口进入避让空间。通过部分遮挡，在避免发生误触，并且起到限位作用的同时，便于安装第一转动臂41，可以有效节约工时，提高装配的效率。
根据本申请的一些实施例，如图21、图26、图29、图31、图45-图48所示，联锁支架20可以具有安装空间204，第二转动臂42位于安装空间204内，并且安装空间204内设有第二挡板26，第二挡板26的至少一部分位于第二转动臂42的靠近第一门勾11的一侧，通过设置第二挡板26可以避免手指等接触第二转动臂42，避免因误触第二转动臂42而驱动第二杠杆40转动，避免第二杠杆40转动而误触微动开关进而影响微波炉1000的使用安全性。
具体地，参照图45-图48所示，由于第二挡板26的至少一部分位于第二转动臂42的靠近第一门勾11的一侧，进而在关门方向上，第二挡板26与第二转动臂42至少部分错开，第二挡板26位于远离第一门勾11的一侧。当手指或长条状物体等沿关门方向***安装空间204，可以接触到第二挡板26而不容易接触到第二转动臂42，从而可以避免误触第二转动臂42而使第二杠杆40发生转动。
在安装空间204由支架本体22与盖体23限定的实施例中，支架本体22和盖体23中至少一个设有第二挡板26，即第二挡板26可以设在支架本体22上，也可以设在盖体23上，或者在支架本体22和盖体23上皆设第二挡板26，以防止手指或其他物体误触第二转动臂42。在一些具体的实施例中，如图43-图48所示，支架本体22和盖体23上皆设第二挡板26，两个第二挡板26可以拼接为一体，进而在平行于转动轴线的方向上，拼接后第二挡板26所延伸的距离更长，由此所能实现的防止手指或其他物体误触第二转动臂42的效果更好。
需要说明的是，第二挡板26的至少一部分在沿转动轴线方向的投影可以是如图46所示的一个弧段，该弧段的一端沿关门方向朝第一门勾11延伸，该弧段的另一端沿垂直于关门方向向如图28所示的向上方向延伸。也可以是其他形状，本申请实施例不做特殊限制。
在联锁装置100包括第二挡板26的实施例中，如图35-图40、图45和图46所示，第二挡板26的一部分可以沿关门方向延伸，并且位于第二杠杆40的转轴与第一门勾11之间，一方面，可以对第一门勾11起到限位和导向作用，第二挡板26的一部分可以作为第一门勾11移动的轨道，第一门勾11在第二挡板26的该部分上沿关门方向移动，进而准确与第一配合部45相抵，以驱动第二杠杆40转动。另一方面该部分位于转轴与第一门勾11之间，有利于避免手指等异物碰触到第二杠杆40的转轴而导致误触发微动开关。
根据本申请的一些实施例，如图44所示，联锁支架20可以具有安装空间204，第三转动臂43位于安装空间204内，并且安装空间204内设有第三挡板27，第三挡板位于第三转动臂43的靠近第一门勾11的一侧，可以避免手指或其他物体等接触第三转动臂43，避免误触第三转动臂43而驱动第二杠杆40转动进而影响微波炉1000使用的安全性。
具体而言，在沿关门方向上，第三挡板27与门勾的投影至少一部分重合。并且，沿关门方向第三挡板较第三转动臂43更靠近第一门勾11，进而第三档板27可以对手指等异物起到止挡作用，
在联锁支架20包括支架本体22与盖体23限定的实施例中，如图44所示，支架本体22和盖体23中至少一个设有第三挡板，即第三挡板可以设在支架本体22上，也可以设在盖体23上，或者在支架本体22和盖体23上皆设第三挡板，以防止手指或其他物体误触第三转动臂43。
根据本申请的一些实施例，如图19-图43所示，联锁装置100还包括监控开关201和第一杠杆30。其中，监控开关201设于联锁支架20，第一杠杆30可转动地设于联锁支架20，第一门勾11在驱动第二杠杆40转动之前，驱动第一杠杆30沿第二方向转动以触发监控开关201，由此可以实现监控开关201、第一微动开关202和第二微动开关203的有序触发。
在关门过程中，第一门勾11首先与联锁支架20上的第一杠杆30接触并驱动第一杠杆30沿第二方向(如图29所示的逆时针方向)转动，转动至预设角度时第一杠杆30触发监控开关201。然后第一门勾11与第二杠杆40接触并驱动第二杠杆40沿第二方向(如图29所示的顺时针方向)转动，转动至第一预设角度时触发第一微动开关202，继续转动至第二预设角度时触发第二微动开关203。由此，实现监控开关201、第一微动开关202和第二微动开关203的依次有序触发。
根据本申请的一些实施例，如图49和图50所示，第一杠杆30可以包括第一驱动臂31，第一驱动臂31可以设有第一驱动部33，第一驱动部33用于驱动监控开关201。
需要说明的是，第一驱动部33在第一驱动臂31上的设置位置可以根据空间布置等实际情况灵活设置。例如，在第一驱动臂31的长度方向上，第一驱动部33可以设于第一驱动臂31的中部或者端部等任意位置。
在一些实施例中，第一驱动部33可以为设于第一驱动臂31沿轴向一侧的凸起，使第一驱动部33与监控开关201配合过程中，不受第一驱动臂31的干扰，避免第一驱动臂31误触监控开关201的风险。
在安装空间204由支架本体22和盖体23限定的实施例中，如图19、图24、图28、图30、图43、图44所示，监控开关201设于盖体23的背向支架本体22的一侧，盖体23设有第一通孔231，第一杠杆30设有第一驱动部33，第一驱动部33可以由第一通孔231穿过，以伸出至盖体23背向支架本体22的一侧。在第一杠杆30转动过程中，第一驱动部33在第一通孔231内随之转动，以便于触发监控开关201。监控开关201可以设于安装空间204外，以避免与安装空间204内的部件产生位置干涉，如避免与缓冲关门组件50干涉，位置排布更合理。
并且，如图21、图26、图29、图31、图49-图51所示，第一杠杆30还可以包括第二驱动臂32，第二驱动臂32位于第一驱动臂31靠近第一门勾11的一侧，换言之，第一驱动臂31位于第二驱动臂32沿第二方向的超前侧。
第一门勾11适于与第一驱动臂31相抵以驱动第一杠杆30转动。如图28-图32所示，在关门过程中，第一门勾11可以与第一驱动臂31相抵，以驱动第一驱动臂31绕第一杠杆30的转动轴线沿第二方向转动，从而带动第一驱动部33转动，使第一驱动部33能够转动至触发监控开关201的位置，使监控开关201打开。
如图19-图21所示，在关门状态下，第一配合部45位于第一驱动臂31和第二驱动臂32之间，可以确保第一配合部45不被手指或其他物体等接触。具体地，当手指或其他物品等***安装空间204后，一开始会触碰到第一驱动臂31，使第一杠杆30沿第二方向转动，但随着第一杠杆30转动，第二驱动臂32会与手指等产生位置干涉，阻碍手指继续***，从而不会碰到第二杠杆40的第一配合部45，第二杠杆40不会被触碰转动，第一微动开关202和第二微动开关203不被会触发；而第一门勾11***安装空间204后，由于第一门勾11设有避让第二驱动臂32的凹部，使第二驱动臂32不会阻碍第一门勾11继续***，第一门勾11能够碰到第一配合部45，从而驱动第二杠杆40转动。
在本申请的一些实施例中，如图34、图49和图51所示，在第一杠杆30的轴向上，第二驱动臂32的至少一侧表面可以设有减薄区域39，以使第一杠杆30安装于联锁支架20时，第二驱动臂32设有减薄区域39处能够与联锁支架20形成一定间隙。在第一杠杆30被误触导致沿第二方向转动至触发监控开关201的位置时，可以通过关门使第一门勾11由该间隙处强行穿过并移动至第一驱动臂31和第二驱动臂32之间，然后可以通过开门动作使第一门勾11带动第一杠杆30沿第一方向转动复位。
例如如图19所示，联锁支架20包括支架本体22和盖体23，第一杠杆30安装于支架本体22和盖体23之间内，减薄区域39可以为设于第二驱动臂32朝向支架本体22一侧的缺口槽，使第二驱动臂32与支架本体22之间形成上述间隙。
此外，在本申请的一些实施例中，如图57和图58所示，第一门勾11的厚度可以沿关门方向递减，使第一门勾11如图57所示的后端厚度较小，前端厚度较大。在第一杠杆30误触发监控开关201的状态下，第一门勾11的前厚后薄的结构使第一门勾11更易于由减薄区域39移动至第一驱动臂31和第二驱动臂32之间，解决非正常触发问题更容易。
在本申请的一些实施例中，如图48和图51所示，在第一杠杆30的轴向上，第一驱动臂31与第一配合部45可以间隔开预定间隙，以确保第一驱动臂31沿第二方向转动至第一配合部45的位置时，第一驱动臂31与第一配合部45不接触，进而不会驱动第二杠杆40转动，避免出现门体200未完全闭合而监控开关201和微动开关被全部触发的异常情况。
根据本申请的一些实施例，如图39和图40所示，联锁装置100还包括弹性件34，弹性件34连接联锁支架20和第第一杠杆30。例如弹性件34可以为螺旋弹簧，螺旋弹簧可以为一个或者多个。举例而言，在图19-图34所示的示例中，弹性件34为拉簧，且为两个，如图49-图51所示，第一杠杆30设有连接部35，连接部35为设于第一杠杆30背向第一驱动部33的侧面的凸起。每个拉簧的一端与联锁支架20连接，另一端均与连接部35连接，且两个拉簧的一端间隔开一定距离。
此外，弹性件34具有第一驱动状态。在第一驱动状态，弹性件34向第一杠杆30施加沿第二方向转动的驱动力，以使第二驱动臂32带动第一门勾11沿关门方向移动。
具体地，如图28-图32所示，在关门过程中，第一门勾11沿关门方向移动，移动至第一驱动臂31和第二驱动臂32之间并与第一驱动臂31相抵，以驱动第一杠杆30开始沿第二方向转动；在第一杠杆30沿第二方向开始转动时或转动较小角度后，弹性件34处于第一驱动状态以自动驱动第一杠杆30沿第二方向转动，使第二驱动臂32带动第一门勾11继续沿关门方向移动，实现自动关门作用。此时，即使用户撤销对门体200的关门作用力，也能保证门体200关闭到位，保证第一门勾11能够沿关门方向移动至三个开关件均被触发。一方面使用户操作省力、方便，另一方面可以避免出现关门不到位的问题。
在一些实施例中，如图33所示，弹性件34具有第二驱动状态。在第二驱动状态，弹性件34向第一杠杆30施加沿第一方向转动的驱动力。在关门过程中，第一门勾11能够与第一驱动臂31相抵，以使弹性件34由第二驱动状态切换至第 一驱动状态。
具体地，在开门状态下，在弹性件34的作用下，第一杠杆30能够保持在所需位置，一方面避免第一杠杆30未受第一门勾11作用的情况下沿第一方向转动而误触发监控开关201，另一方面，可以保证第一门勾11关门过程中能够顺利移动至第一驱动臂31和第二驱动臂32之间，避免第一杠杆30转动而影响第一门勾11与第一杠杆30配合。并且通过第一门勾11与第一驱动臂31相抵驱动第一杠杆30沿第二方向转动，使弹性件34随第一杠杆30的转动及时切换驱动状态，保证弹性件34能够及时起到驱动关门作用。
在关门状态下，弹性件34处于第一驱动状态，使第一杠杆30能够通过第二驱动臂32与第一门勾11相抵，保证门体200保持在关门状态。在需要开门时，用户控制第一门勾11沿开门方向移动，并与第二驱动臂32相抵，以使第一杠杆30沿第一方向转动。当第一杠杆30转动至一定角度时，弹性件34由第一驱动状态切换至第二驱动状态，以使弹性件34能够驱动第一杠杆30沿第一方向转动以及时解除对第一门勾11的阻力，使门体200能够轻松打开。
在弹性件34为弹簧的实施例中，无论是第一驱动状态还是第二驱动状态，弹簧始终保持拉伸状态。
根据本申请的一些实施例，如图35-图39和图46所示，联锁支架20可以设有第一限位部21。在关门状态下，第一限位部21能够与第一杠杆30相抵，以阻止第一杠杆30沿第二方向转动。换言之，第一限位部21能够限制第一杠杆30沿第二方向转动的极限位置，避免第一杠杆30转动角度过大而对监控开关201或第一门勾11造成损坏。
例如，在包括弹性件34的实施例中，弹性件34驱动第一杠杆30沿第二方向转动，以带动第一门勾11沿关门方向移动，实现自动关门动作；当转动至第一杠杆30与第一限位部21相抵时，第一限位部21的限位作用使第一杠杆30受力平衡，而不继续在弹性件34的驱动下转动，第一杠杆30能够保持在与第一门勾11稳定配合、使门体200保持关门状态的位置。
根据本申请的一些实施例，如图35-图40所示，联锁支架20可以设有第二限位部24。在开门状态下，第二限位部24能够与第一杠杆30相抵，以阻止第一杠杆30沿第一方向转动。换言之，第二限位部24能够限制第一杠杆30沿第一方向转动的极限位置，避免第一杠杆30沿第一方向转动的角度过大而发生位置干涉，避免第一门勾11关门时无法正常与第一杠杆30相接触配合，避免影响用户的使用体验。
根据本申请的一些实施例，如图19-图34、图39和图40所示，联锁装置100还可以包括缓冲关门组件50。缓冲关门组件50连接联锁支架20和第一杠杆30，例如与第一杠杆30的第一驱动臂31相连。
在关门过程中，缓冲关门组件50用于向第一杠杆30施加与第二方向相反的缓冲力，以实现关门缓冲作用，避免关门过程中门体200与机体发生剧烈碰撞，也有利于降低关门噪音。
本申请对缓冲关门组件50的具体结构不做特殊限制，只需要满足能够起到缓冲关门作用即可。例如，缓冲关门组件50可以包括阻尼器、弹片或者压簧等。
举例而言，在一些具体实施例中，继续参照图39和图40所示，缓冲关门组件50包括缓冲件51和连接件52。其中，缓冲件51的一端与联锁支架20可转动连接，连接件52分别与缓冲件51的另一端和第一驱动臂31可转动连接，以使第一杠杆30转动过程中，缓冲件51能够起到缓冲作用，而可转动连接结构则使可以适应第一杠杆30的转动，避免发生卡死。
此外，参照图39、图40、图49和图50所示，第一驱动臂31具有驱动面36，连接件52可转动地安装于第一驱动臂31，且如图26和图27所示，在开门状态下连接件52与驱动面36呈预设角度，缓冲件51的另一端与连接件52可转动连接。在关门过程中，第一杠杆30沿第二方向转动预设角度后，驱动面36能够与连接件52相抵，以带动连接件52转动。
由于开门状态下，连接件52与驱动面36之间呈预设角度布置，使第一门勾11刚与第一杠杆30接触并驱动第一杠杆30沿第二方向转动时，缓冲件51不会向第一杠杆30施加缓冲力，使第一门勾11驱动第一杠杆30转动更容易。
在一些具体实施例中，如图22、图27和图49、图50所示，第一驱动臂31朝向缓冲关门组件50的一侧设有凹槽37，凹槽37的底壁面形成为驱动面36，凹槽37的其中一个侧面与连接件52孔轴连接，凹槽37的其中另一个侧面设有与驱动面36间隔开一定距离的弯勾38。缓冲件51为阻尼器，阻尼器由凹槽37的槽口与连接件52孔轴连接。联锁装置100还包括与第一杠杆30相连的弹性件34。
在开门状态下，弹性件34向第一杠杆30施加沿第一方向转动的驱动力，使第一门勾11能够顺利移动至与第一驱动臂31相抵，此时连接件52与驱动面36呈预设角度，使阻尼器不产生缓冲力。在关门过程中，第一门勾11与第一驱动臂31接触并驱动第一杠杆30沿第二方向转动，由于阻尼器无缓冲力，使第一门勾11驱动第一杠杆30仅需克服弹性件34的驱动力，阻力更小；当转动至连接件52与驱动面36相抵时，弹性件34切换状态至向第一杠杆30施加沿第二方向转动的驱动力，以主动驱动第一杠杆30转动、第一门勾11移动以及门体200关闭，此时阻尼器产生缓冲力，以降低关门噪音。 在开门过程中，第一门勾11拉动第一杠杆30沿第一方向转动，连接件52相对于第一驱动臂31转动，使连接件52与驱动面36之间呈一定夹角，弯勾38与连接件52相抵，以防止夹角过大、防止连接件52由凹槽37脱出，保证连接件52与第一杠杆30稳定连接。
举例而言，在另一些具体实施例中，缓冲关门组件50可以包括缓冲件51，缓冲件51为弹片或压簧，缓冲关门组件50形成为缓冲储能组件。具体地，弹片的一端与联锁支架20相连，第一杠杆30与弹片的另一端相抵，并且弹片可以发生弹性变形，以蓄能。
在关门过程中，第一杠杆30沿第一方向转动并挤压弹片的另一端，使弹片弯曲程度增大并积蓄能量，起到缓冲作用和储能作用；在开门过程中，弹片可以释放所储蓄的能量，以向第一杠杆30施加沿第一方向转动的驱动力，使第一杠杆30能够推动第一门勾11和门体200向开门方向移动，起到助推开门的作用。在关门状态下，弹片作用在第一杠杆30上的驱动力的方向指向第一杠杆30的转动中心或者转动中心附近，此时弹片不提供第一杠杆30转动方向的分力或只提供较小的分力，保证门体200能够被紧紧关上。
在本申请的一些实施例中，如图52和图53所示，在第一杠杆30的轴向上，连接件52的侧面可以设有用于避让第一配合部45的避让缺口521。通过设置避让缺口521，在第一杠杆30的轴向上连接件52与第一配合部45的端面存在间隙，可以确保在第一杠杆30转动过程中，避免连接件52与第一配合部45接触而触发第二杠杆40转动，避免发生监控开关201与微动开关的触发顺序混乱。
下面参考附图详细描述根据本申请的一个具体实施例的微波炉1000的联锁装置100，值得理解的是，下述描述只是示例性说明，而不能理解为对申请的限制。
如图19-图58所示，根据本申请实施例的微波炉1000包括门体200、机体和联锁装置100。联锁装置100包括第一门勾11、第二门勾12、联锁支架20、第一挡板25、第二挡板26、第三挡板、第一杠杆30、第二杠杆40、监控开关201、第一微动开关202、第二微动开关203、弹性件34、缓冲关门组件50、驱动件53和斜块54。
其中，如图21、图41和图42所示，门体200绕竖直轴线可转动地安装于机体，第一门勾11和第二门勾12固设于门体200，且第二门勾12位于第一门勾11上方。联锁支架20安装于机体，且包括支架本体22和盖体23，以限定出安装空间204。安装空间204的侧壁设有避让凹槽205，支架本体22包括第一挡板25，第一挡板25部分遮挡避让凹槽205和安装空间204的连通口。并且，安装空间204内设有第二挡板26和第三档板27。其中，第二挡板26为滑梯状板体，第三档板27为矩形板体。
如图35、图36、图39和图40所示，第一杠杆30和第二杠杆40可转动地安装于安装空间204，第一杠杆30包括设有第一驱动臂31、第二驱动臂32和第一驱动部33，第一驱动部33穿过盖体23的第一通孔231；第二杠杆40包括设有第一配合部45的第一转动臂41、设有第二配合部44的第二转动臂42、设有第三配合部46的第三转动臂43，第二配合部44穿过盖体23的第二通孔232。并且，第二挡板26的弧形段位于第二转动臂42的靠近第一门勾11的一侧，平直段位于第二杠杆40的转轴和第一门勾11之间。第三挡板位于第三转动臂43的靠近第一门勾11的一侧。此外，第一转动臂41位于避让凹槽205内，第一配合部45伸入安装空间204。
如图19、图21、图45、图46和图48所示，第二微动开关203设于安装空间204内，监控开关201和第一微动开关202设于盖体23背向支架本体22的一侧。支架本体22设有第三通孔221，弹性件34设于支架本体22背向盖体23的一侧，且第一杠杆30的连接部35穿过第三通孔221以与弹性件34相连。
此外，斜块54可竖向移动地安装于支架本体22，驱动件53两端分别与斜块54和支架本体22相抵，以向斜块54施加向上的驱动力。
如图23-图26所示，在开门状态下，第一门勾11和第二门勾12与机体分离。驱动件53驱动斜块54位于高位。第一杠杆30在弹性件34的拉力作用下沿顺时针方向转动至与支架本体22的边沿相抵的极限位置，且与监控开关201脱离配合；第二杠杆40处于与第一微动开关202和第二微动开关203分离的位置。
如图28-图32所示，在关门过程中，推动门体200，使第一门勾11和第二门勾12沿关门方向移动，即向后移动。其中第一门勾11在第二挡板26的限位下沿关门方向移动。第一门勾11的后端伸至第一驱动臂31和第二驱动臂32之间，并与第一驱动臂31相抵，以推动第一杠杆30沿逆时针方向转动；第一杠杆30转动预设角度时，弹性件34的拉力方向切换至驱动第一杠杆30沿逆时针方向转动，以使第一杠杆30的第二驱动臂32自动拉动第一门勾11向后移动，且连接件52与驱动面36接触，驱动面36驱动连接件52运动，缓冲件51起到缓冲作用；第一杠杆30转动使第一驱动部33触发监控开关201；然后第一门勾11移动至与第二杠杆40的第一配合部45接触，可以驱动第二杠杆40沿顺时针方向转动。第二杠杆40的第二配合部44和第三配合部45依次触发第一微动开关202和第二微动开关203。关门过程中，如图37和图38 所示，第二门勾12与斜块54相抵，斜块54压缩驱动件53使第二门勾12的勾部移动至斜块54的后侧，实现斜块54对第二门勾12的限位，以保持门体200关闭。
如图19-图21所示，当第一杠杆30转动至与第一限位部21相抵时停止转动，第二杠杆40触发第二微动开关203后停止转动。此时，在弹性件34的拉力作用下，第一杠杆30的第二驱动臂32止挡第一门勾11，进而使门体200保持在关门状态，第一杠杆30和第二杠杆40保持在使监控开关201、第一微动开关202和第二微动开关203导通的位置。
在开门过程中，如图33所示，门体200反向转动以打开，使第一门勾11向前移动。移动过程中，首先撤销对第二杠杆40的止抵力，第二杠杆40在第一微动开关202和第二微动开关203的反弹力作用下逆时针转动，以解除对第一微动开关202和第二微动开关203的触发；第一门勾11移动过程中还与第二驱动臂32相抵，以带动第一杠杆30克服弹性件34弹力并顺时针转动，使第四部45解除对监控开关201的触发；当转动至弹性件34的拉力方向切换至驱动第一杠杆30沿顺时针方向转动时，在弹性件34的驱动下，第一杠杆30自动复位至与第一限位部21相抵的位置，并停留在该位置，并且第一杠杆30可以驱动第一门勾11向前移动，以使门体200弹开。在开门过程中，如图37和图38所示，第二门勾12再次与斜块54相抵，斜块54压缩驱动件53使第二门勾12的勾部移动至斜块54的前侧，解除斜块54对第二门勾12的限位，使门体200能够打开。
综上，通过第一门勾11与两个杠杆配合，分别触发三个开关件，开关件不直接与第一门勾11直接发生接触，且三个开关件能够按照监控开关201、第一微动开关202、第二微动开关203的顺序有序触发，保证了设备的安全性。并且联锁装置100的结构紧凑，生产成本低。
请一并参阅图59和图60，本申请第四方面实施方式的一种微波炉1000，微波炉1000包括门体200、联锁支架20和阻尼组件30a。门体200具有第二门勾12和第一门勾11，门体200活动连接联锁支架20，联锁支架20上固定有第一开关21a、第二开关22a和第三开关23a。阻尼组件30a安装在联锁支架20上，阻尼组件30a包括阻尼器31a和驱动杠杆32a，驱动杠杆32a转动连接联锁支架20和阻尼器31a，微波炉1000被配置为在门体200关闭的过程中，第一门勾11直接抵触第一开关21a以触发第一开关21a，第二门勾12直接抵触第二开关22a以触发第二开关22a，第一门勾11通过驱动杠杆32a触发第三开关23a。
本申请实施方式的微波炉1000，第一门勾11直接抵触第一开关21a来触发第一开关21a，第二门勾12直接抵触第二开关22a来触发第二开关22a，这样可以保证第一开关21a、第二开关22a和第三开关23a按顺序触发，避免了开关触发顺序混乱的问题。
具体地，微波炉1000包括门体200，门体200可以采用双层玻璃的门体；门体还可以采用防漏波玻璃的门体。采用玻璃门体的其中一个好处是方便用户在外面观察微波炉1000内的食物情况。另外，门体200的外表面可设置有把手，方便用户进行开关门操作。门体200上安装有两个门勾，两个门勾分别为第二门勾12和第一门勾11。微波炉1000包括第一开关21a、第二开关22a和第三开关23a。第一开关21a可以是监控开关，监控开关用于监控整个微波炉1000的回路；第二开关22a可以是次级开关，次级开关用于控制灯和散热风扇或其它组件的开启；第三开关23a可以是初级开关，初级开关用于控制微波炉1000的微波功能。第二门勾12用于触发第二开关22a，也即是说，第二门勾12触发次级开关；第一门勾11直接触发第一开关21a，也即是说，第一门勾11直接触发监控开关；第一门勾11通过驱动杠杆32a触发第三开关23a，也即是说，第一门勾11间接触发初级开关。
在用户使用微波炉1000的过程中，三个开关的触发顺序尤为重要。在关门过程中，触发顺序应为：首先触发监控开关，其次触发次级开关，最后触发初级开关。如此，可以保证用户的使用安全。在开门过程中，触发顺序应为：首先触发初级开关，其次触发次级开关，最后触发监控开关。如此，可以保证用户的使用安全。然而，相关技术中的微波炉由于门勾布局形式不同或活动门勾等情况，容易造成的关门过程中三个开关触发顺序的混乱的问题。具体问题产生的原因是：用户在用手推门以关闭门体的情况下，第二门勾在力的作用下加速触发次级开关，并且由于驱动杠杆连接阻尼器，驱动杠杆在运动过程中减速，手推门的加速超过了驱动杠杆转动速度，就会造成先触发初级开关，后触发监控开关的情况，因此发生三个开关触发顺序的混乱，三个开关触发顺序的混乱会影响用户的使用安全。
本申请实施方式的微波炉1000，第一门勾11直接抵触监控开关来触发监控开关，第二门勾12直接抵触次级开关来触发次级开关，第一门勾11通过驱动杠杆32a触发初级开关，这样可以保证监控开关、次级开关和初级开关按顺序触发，避免了开关触发顺序混乱的问题。
请再次参阅图59和图60，在某些实施方式中，第二门勾12和/或第一门勾11是固定在门体200。
如此，第二门勾12和第一门勾11可以进一步保证第一开关21a、第二开关22a和第三开关23a按顺序触发。
具体地，第二门勾12和第一门勾11材料可选自金属，如铁、铝、不锈钢及合金等。第二门勾12和第一门勾11整体 呈长条状，末端设有钩状部，如此可以便于卡合。在本申请的实施方式中，门体200包括两个门勾，即第二门勾12和第一门勾11。在某些实施方式中，门体200还可以包括多个门勾以辅助开关门，门勾数量可根据实际情况来设定，例如：门勾的数量可以是3个、4个、或多于4个，此处不作限定。
在一个实施例中，第二门勾12是固定在门体200上的，第一门勾11可以活动地安装在门体200上。在另一个实施例中，第一门勾11是固定在门体200上的，第二门勾12可以活动地安装在门体200上。在又一个实施例中，第二门勾12和第一门勾11都是固定在门体200上的。如此，固定设置的门勾可以保证触发开关的稳定性，避免由于门勾活动而导致触发不及时、触发失灵等情况。门勾固定在门体200上还可以保证连接的稳定性。
请一并参阅图60和图61，在某些实施方式中，阻尼组件30a还包括摆动块33a，摆动块33a转动连接驱动杠杆32a和阻尼器31a。
如此，摆动块33a与驱动杠杆32a和阻尼器31a转动连接，实现了分体式的转动连接，可以避免关门不顺畅甚至停滞现象。
具体地，阻尼器31a通过摆动块33a与驱动杠杆32a转动连接，实现了分体式的转动连接，即摆动块33a与驱动杠杆32a转动连接，摆动块33a与阻尼器31a转动连接，在第一门勾11向驱动杠杆32a施加作用力的情况下，驱动杠杆32a转动一预设角度后带动摆动块33a压缩阻尼器31a，阻尼器31a被压缩时向第一门勾11提供阻尼并发生转动。可以理解的是，驱动杠杆32a带动摆动块33a转动时，具有预设角度的间隔，使得第一门勾11与驱动杠杆32a抵接时，阻尼器31a并未产生阻尼作用。避免关门不顺畅甚至停滞现象。
值得一提，阻尼组件30a安装在联锁支架20上，驱动杠杆32a可通过联锁支架20上的转轴转动连接在联锁支架20上。阻尼器31a可以是直线式阻尼器。可以理解，在其它实施方式中，阻尼器31a还可以其它阻尼器，例如旋转阻尼器。
请再次参阅图61，在某些实施方式中，驱动杠杆32a开设有容置槽321，容置槽321的顶部开设转动空间322，容置槽321的底部开设有摆动空间323，摆动块33a的一端转动收容在转动空间322，摆动块33a的另一端收容在摆动空间323，摆动空间323用于提供驱动杠杆32a转动相对于摆动块33a的空间。
如此，可以使得驱动杠杆32a在转过预设角度后再带动摆动块33a转动。
具体地，驱动杠杆32a开设有容置槽321，容置槽321的顶部包括转动空间322，转动空间322可以收容摆动块33a的顶端。在一个实施例中，转动空间322大致呈圆柱形，摆动块33a的顶端呈与转动空间322相匹配的圆柱形。容置槽321的底部包括摆动空间323，摆动块33a的另一端收容在摆动空间323，摆动空间323用于提供驱动杠杆32a转动预设角度的空间。
摆动空间323的设置可以使得驱动杠杆32a刚开始转动时，不会作用于摆动块33a，进而不会压缩阻尼器31a，使得第一门勾11在抵接驱动杠杆32a初期，不会受到阻尼器31a的阻力而引起回弹甚至停滞现象。摆动空间323的大小可以决定预设角度的大小，可以根据实际情况进行标定。
请一并参阅图62、图63和图64，在某些实施方式中，驱动杠杆32a包括间隔的第一卡合区域301和第二卡合区域302，第一卡合区域301开设有容置槽124，在第一门勾11向驱动杠杆32a运动的情况下，第一门勾11从第二卡合区域302下方经过后与第一卡合区域301抵接以驱动驱动杠杆32a转动。如此，可以使得第一门勾11驱动驱动杠杆32a转动后，第二卡合区域302能够勾住第一门勾11来带动第一门勾11加速关门。
请一并参阅图65至图68，在某些实施方式中，阻尼组件30a包括弹性件34，弹性件34和驱动杠杆32a位于联锁支架20的相背两侧，联锁支架20开设有第三通孔221，驱动杠杆32a通过第三通孔221连接弹性件34，弹性件34用于带动驱动杠杆32a加速转动以使驱动杠杆32a带动门体200加速。
如此，可以实现第一门勾11的先加速，再减速的过程。
具体地，位于联锁支架20相背两侧的弹性件34和驱动杠杆32a，可以将相关结构件分散布置，避免在联锁支架20同一侧面太多结构件而导致空间减少及重量过于集中，不利于结构件的配置。
弹性件34可以向驱动杠杆32a提供拉力以使驱动杠杆32a带动第一门勾11加速，也可以向驱动杠杆32a提供推力以使驱动杠杆32a带动第一门勾11加速。在图66和图67所示的实施方式中，弹性件34向驱动杠杆32a提供拉力以使驱动杠杆32a带动第一门勾11加速。
由于驱动杠杆32a可带动第一门勾11加速，使得在加速阶段，门体200可以依靠驱动杠杆32a的作用力去关闭。而在第一门勾11加速过程中，当驱动杠杆32a转动预设角度后，阻尼器31a被压缩。随着关门过程的继续，摆动块33a持续压缩阻尼器31a，阻尼器31a的压缩量增大，提供的阻尼力也在增大，当阻尼器31a提供的阻尼力大于驱动杠杆32a提供的驱动力时，第一门勾11开始减速，在减速阶段，使得门体200关闭时的噪音不至于太大。在本申请实施方式中，阻 尼器31a被压缩时，可以转动，可配合转动件和摆动块33a转动的方式，使得第一门勾11进入腔体时更顺畅。
在图59所示的实施方式中，联锁支架20上还安装有盖体23，盖体23内设置有容置空间。盖体23可通过螺钉、过盈配合、焊接、卡扣等方式安装在联锁支架20上，在图59所示的实施方式中，盖体23通过卡扣安装在联锁支架20上。
在某些实施方式中，在第一门勾11与驱动杠杆32a分离的情况下，弹性件34对驱动杠杆32a的作用力方向位于弹性件34与驱动杠杆32a的连接处和驱动杠杆32a转轴的连线上方，在驱动杠杆32a受到第一门勾11作用力的情况下，弹性件34对驱动杠杆32a的作用力方向位于弹性件34与驱动杠杆32a的连接处和驱动杠杆32a转轴的连线下方。
如此，可以使得驱动杠杆32a在关门前和关门时具有不同的转动趋势，有利于实现紧密关门。
在某些实施方式中，请参阅图69，弹性件34对驱动杠杆32a的作用力F方向位于弹性件34与驱动杠杆32a的连接处和驱动杠杆32a转轴的连线L上方，驱动杠杆32a在弹性件34的作用力下，具有沿第一方向的转动趋势。请参阅图70，弹性件34对驱动杠杆32a的作用力F方向位于弹性件34与驱动杠杆32a的连接处和驱动杠杆32a转轴的连线L下方，驱动杠杆32a在弹性件34的作用力下，具有沿第二方向的转动趋势。第一方向不同于第二方向。在图示中，第一方向为顺时针方向，第二方向为逆时针方向。
第一门勾11还没有抵接驱动杠杆32a时，驱动杠杆32a静止，弹性件34的作用力作用于驱动杠杆32a，使得驱动杠杆32a具有顺时针转动的趋势。在第一门勾11抵接驱动杠杆32a(如抵接第一卡合区域301)，驱动杠杆32a在第一门勾11的作用下，发生逆时针转动，使得弹性件34与驱动杠杆32a的连接处也发生逆时针转动，弹性件34对驱动杠杆32a的作用力方向切换至上述连线下方，驱动杠杆32a从具有顺时针转动趋势转换为逆时针转动趋势，此时，驱动杠杆32a没有受到限位，在弹性件34的作用下，继续沿逆时针转动进而带动第一门勾11加速。
驱驱动杠杆32a具有转动趋势转换的过程，会使得驱动杠杆32a转动的角度较大，驱动杠杆32a转动角度较大可以带动第一门勾11，进而使得门体200关上时更紧密。
需要说明的，初始状态下，弹性件34与驱动杠杆32a的连接处的位置，与驱动杠杆32a转动趋势转换的临界位置之间的距离(角度)小于预设角度。较佳地，初始状态下，弹性件34与驱动杠杆32a的连接处的位置，接近驱动杠杆32a转动趋势转换的临界位置，使得在第一门勾11抵接到驱动杠杆32a时，初始速度较大的第一门勾11就可使驱动杠杆32a沿逆时针转动而将转动趋势转换，无需花费太多第一门勾11的动能来进行转动趋势的转换。
请再次参阅图66和图67，在某些实施方式中，弹性件34包括第一弹性件341和第二弹性件342，驱动杠杆32a上设有连接结构324，第一弹性件341与第二弹性件342均连接连接结构324，第一弹性件341与第二弹性件342之间形成的夹角为锐角。
如此，通过第一弹性件341与第二弹性件342的合力来对驱动杠杆32a进行驱动。
具体地，在驱动杠杆32a转动过程中，其中一个弹性件可以被拉伸更长，另一个弹性件可以被压缩，两者所产生的合力大小在驱动杠杆32a转动过程中，变化幅度较小，即使在门体200关闭到位的情况下，能够使驱动杠杆32a对第一门勾11产生较大的抵持力，使得门体200关闭更紧密。在一个示例中，第一弹性件341和第二弹性件342可均为拉簧。第一弹性件341位于第二弹性件342的上方。第一弹性件341的一端勾住联锁支架20上的定位柱，另一端勾住连接结构324。第二弹性件342的一端勾住联锁支架20上的另一定位柱，另一端勾住连接结构324。第一弹性件341与第二弹性件342形成的夹角为锐角，锐角可以是30度、35度、40度等角度，在此不作具体限定。
请再次参阅图60和图62，在某些实施方式中，联锁支架20上安装有保护块24a，保护块24a活动地安装在联锁支架20上，在第一门勾11与驱动杠杆32a脱离的情况下，保护块24a对驱动杠杆32a进行限位，在门体200关闭过程中，第一门勾11驱动保护块24a移动以解除保护块24a对驱动杠杆32a的限位。
如此，保护块24a可以在第一门勾11与驱动杠杆32a脱离的情况下，防止驱动杠杆32a转动。
具体地，保护块24a可以在联锁支架20上运动，保护块24a在联锁支架20上运动的方式包括移动、转动或其它复合运动，保护块24a的运动方式能够对驱动杠杆32a进行限位和解除限位即可，此处不作限定。在一个实施方式中，在第一门勾11与驱动杠杆32a脱离的情况下，保护块24a能够阻碍驱动杠杆32a转动，保护块24a在联锁支架20上可以沿竖直方向移动，在关门的情况下，第一门勾11将保护块24a沿竖直向下方向推动，如此保护块24a解除对驱动杠杆32a的限位，驱动杠杆32a能够正常转动。在某些实施方式中，保护块24a内开设有限位槽，限位槽用于收容部分驱动杠杆32a，在限位槽收容部分驱动杠杆32a的情况下，保护块24a能够阻碍驱动杠杆32a转动。
请再次参阅图60，在某些实施方式中，微波炉1000包括：斜块40a和第三弹性件50a，斜块40a和第三弹性件50a安装在联锁支架20上，第三弹性件50a抵接斜块40a的底部，斜块40a的顶部具有一导向斜面，导向斜面沿竖直面向联锁支架20内部向上倾斜，在门体200关闭过程中，第二门勾12的末端与导向斜面抵接而使斜块40a下降压缩第三弹性件 50a，在第二门勾12的末端跨过导向斜面的情况下，斜块40a在第三弹性件50a的作用下卡住第二门勾12。
如此，通过斜块40a和第三弹性件50a配合第二门勾12，保证第二门勾12可以直接抵触第二开关22a以触发第二开关22a。
具体地，斜块40a的顶部为导向斜面，导向斜面沿竖直面向联锁支架20内部向上倾斜，也可以理解为，斜块40a靠近第二门勾12的一端的高度低于斜块40a远离第二门勾12的一端的高度。导向斜面是具有一定角度的倾斜平面，第二门勾12可以沿着平面下方运动至平面上方。
第第三弹性件50a包括压簧，在门体200关闭过程中，第二门勾12斜块40a产生作用力，使得第三弹性件50a一直处于压缩状态。在门体200关闭后，第三弹性件50a伸展，斜块40a在第三弹性件50a的作用下向上运动，斜块40a的远离第二门勾12的一端可以卡住第二门勾12。值得一提的是，用户在开关门的情况下，开门与关门要使用的力的大小不同，开门的力通常大于关门的力，用户可以使用较大的力直接将第二门勾12从斜块40a的一端拉出，使得斜块40a不再卡住第二门勾12，如此可以简便开门结构和实现紧密关门。
在某些实施方式中，微波炉1000还包括腔体，门体200转动地连接在腔体的一侧，联锁支架20安装在腔体。
如此，腔体用于存储物品或食物，联锁支架20安装在腔体上可以保证安装的稳定性。
具体地，家用电器1000可包括腔体(图未示)，联锁支架20可以固定在腔体，门体200与腔体转动连接。腔体开设有腔室，腔室前侧具有开口，门体200用于关闭和打开开口。腔室内可以放置待加热的食物。
门体200可转动地连接腔体的一侧，例如，连接在腔体前板的左侧或右侧，形成侧开门式的微波炉1000，联锁支架20可固定在腔体前板。腔体内开设有腔室，用于存储物品或食物。微波炉1000可以对放置在腔室内的物品进行解冻、烹饪等操作。微波炉1000还包括腔体外的壳体，壳体可以保护微波炉1000内的电气件及结构件，同时也避免对用户造成伤害。
