具体实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示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一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接。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。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。
在本申请中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。
本申请的公开提供了许多不同的实施方式或例子用来实现本申请的不同结构。为了简化本申请的公开，本申请中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或参考字母，这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施方式和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的应用和/或其他材料的使用。
相关技术中，家用电器的门锁装置包括安装于门体的门钩以及设置于箱体上的支架，支架上设置有沿横向延伸的滑槽，滑槽中设置有卡合件，卡合件用于勾合门钩，并用于沿着滑槽滑动从而拉动门钩移动进而关闭门体。
但是，由于滑槽的尺寸较长，导致门锁装置的支架尺寸较大，门锁装置占用的空间大。
为了解决上述问题中的至少一个，本申请实施方式提供一种门锁装置及烹饪装置，通过设置能够相对支架旋转的连接件，连接件能够拉动第一门钩关闭门体，减小了门锁装置沿横向的尺寸，进而减小了门锁装置的占用空间。
以下结合附图1至图16对本申请实施方式进行详细说明，图1示出了本申请实施方式中门锁装置的正视图；图2为图1中的门锁装置去掉罩体以及第二驱动件后的内部结构示意图；图3为图1中支架以及限位件的连接示意图；图4为图3的爆炸示意图；图5为图1的局部放大图；图6为图5的爆炸示意图；图7为图2中连接件的正视图；图8为图2中连接件的轴侧图；图9为图1中限位件的结构示意图；图2中直线箭头所示的方向为第一方向，而弧形箭头所示的方向为第一旋转方向。可以理解，第一方向和第一旋转方向均为矢量方向。以第一方向为例，矢量方向可以理解成具有指向性的方向，例如图2中从左向右的方向为第一方向，而从右向左的方向为与第一方向相反的方向，连接件沿逆时针转动的方向为第一旋转方向，而连接件沿顺时针转动的方向为与第一旋转方向相反的方向。
请参照图1至图9，本申请实施方式提供一种门锁装置，可以用于具有门体和箱体的结构中，尤其是可以用于微波炉等家用电器中，门锁装置包括：第一门钩100、支架200、连接件300以及限位件400。
以应用于烹饪器具为例，第一门钩100可以安装于烹饪器具的门体上，连接件300、支架200和限位件400可以安装于烹饪器具的箱体上。其中，第一门钩100包括第一安装部110以及第一钩状部120；第一安装部110用于与门体连接，第一安装部110的实现方式可以有多种，可选地，第一安装部110可以包括安装孔，螺钉可以螺纹连接于安装孔，并将其螺接于门体的侧面；或可选地，第一安装部110可以包括凸台，门体上可以设置有卡槽，凸台可以卡合安装于卡槽中。
第一钩状部120可以通过焊接、螺接、铆接等工艺连接于第一安装部110上，或可选地，两者可以通过一体加工的方式加工成型。第一钩状部120可以凸出于门体，使得门体关闭后，其可以伸入箱体的一侧。
支架200可以为厚度不高的板状结构，其可以用于与箱体连接。支架200连接至箱体的方式可以有多种，例如支架200上设置多个通孔，螺钉可以穿设通孔，并将支架200通过螺母螺接于箱体上；又或者，支架200还可以通过卡扣配合的方式卡合于箱体。
连接件300可转动地连接于支架200，连接件300上可以设置有旋转部330，旋转部330的轴线可以为连接件300相对支架200旋转的轴线，旋转部330可转动地连接于支架200，从而能够使连接件300相对支架200旋转。可以理解，旋转部330可以是转动通孔，支架200上可以设置有凸出的旋转轴，连接件300可以通过转动通孔套设于旋转轴外，从而实现连接件300的旋转。又例如，旋转部330可以为设置于连接件300上的旋转轴，支架200上可以具有转动通孔，旋转轴可以转动连接在转动通孔中。另外，连接件300可以用于勾合第一钩状部120。
在某些实施方式中，连接件300可以包括输出扭矩的动力部件，例如电机等，当连接件300与第一钩状部120勾合后，连接件300可以相对支架200沿第一旋转方向转动，从而拉动第一钩状部120。
在某些实施方式中，门锁装置还可以包括第一驱动件500，第一驱动件500连接在支架200与连接件300之间。即第一驱动件500可以为能够提供动力的结构，例如直线电机、液压缸、弹簧或弹力绳索等。第一驱动件500与连接件300连接，以向连接件300提供可以带动连接件300沿第一旋转方向旋转的扭矩。第一驱动件500用于在限位件400与连接件300分离后，带动连接件300相对支架200沿第一旋转方向旋转，以使连接件300勾合第一钩状部120，从而拉动第一钩状部120沿第一方向移动，进而关闭门体。
可选地，第一驱动件500可以是螺旋弹簧，螺旋弹簧的一端可以连接在支架200上，其另一端可以连接于连接件300上，结构简单且容易实现。进一步可选地，第一驱动件500可以为能提供拉力的拉簧，使得第一驱动件500的安装位置更灵活。
限位件400连接于支架200上，限位件400具有限位部410及滑动面420，可以理解，当第一门钩100在外力作用下沿第一方向移动时，第一钩状部120能够沿滑动面420滑动，以带动限位件400相对支架200旋转，从而可以使得限位部410在抵靠于连接件300的位置以及限位部410与连接件300分离的位置之间往复移动，且当限位部410抵靠于连接件300，限位部410限制连接件300相对支架200沿第一旋转方向的转动，而当限位部410与连接件300分离，连接件300能够在第一驱动件500的作用下相对支架200沿第一旋转方向转动，此时，连接件300能够勾合第一钩状部120，并且拉动第一钩状部120沿第一方向移动以关闭门体。
图10为图1中第一门钩的结构示意图，请参照图10，第一钩状部120包括第一段121、第二段122和第三段123，第一段121沿第一方向延伸，且一端与第一安装部110连接，另一端与第二段122以及第三段123连接。第二段122可以沿朝向旋转部330的方向凸出于第一段121，第三段123可以沿背离旋转部330的方向凸出于第一段121，从而为限位件400 提供可转动的空间。
第一段121、第二段122和第三段123可以通过常见的加工方式例如焊接、铆接或螺接等连接，又或者，三者可以通过注塑、铸造、粉末冶金等一体成型工艺加工而成。可选地，第二段122和第三段123可以为别为条状结构，且连接的延伸方向相反，且两者的延伸方向均与第一方向垂直，第一段121、第二段122及第三段123三者可以大致成“T”字形结构。
且当连接件300勾合第一钩状部120时，滑动面420位于第一钩状部120背离连接件300的一侧，即第二段122用于与连接件300勾合，第三段123能够沿滑动面420滑动，从而使得第一钩状部120沿垂直于第一方向的顶部可以与连接件300勾合，底部可以沿滑动面420滑动，从而能够实现门锁装置关门功能，并且可以简化第一钩状部120的结构。
在某些实施方式中，门锁装置200还包括缓冲件600，缓冲件600连接在支架200与连接件300之间，缓冲件600用于减慢第一钩状部120沿第一方向移动的速度，从而减轻门体和箱体的碰撞，降低噪声。缓冲件600的结构也可以有多种，例如，缓冲件600也可以包括螺旋弹簧等弹性结构，或缓冲件600可以是阻尼器结构，例如直线阻尼器或旋转阻尼器。缓冲件600可以提供弹力阻碍第一钩状部120的移动，可以理解，第一驱动件500提供的动力可以大于缓冲件600的阻力，使得第一钩状部120只会减缓运动速度，而并不会改变运动方向。
可选地，缓冲件600可以是单向阻尼器，当第一门钩100沿第一方向移动时，单向阻尼器可以减慢其移动速度，而当第一门钩100沿与第一方向相反的方向移动时，单向阻尼器不提供阻尼，不会减缓第一门钩100的移动速度，从而在关门时减轻门体与箱体的碰撞，减少噪声，反之，在开门时，缓冲件600不会减缓门体开启速度，提高用户体验。
缓冲件600可以与连接件300连接，从而减缓连接件300沿第一旋转方向的转动速度，进而减缓第一钩状部沿第一方向的移动速度。或者，缓冲件600的输出端可以设置在第一门钩100的移动路径上，当第一门钩100与缓冲件600接触后，其可以减缓第一门钩100沿第一方向的移动速度。
以第一驱动件500是拉簧为例，关门过程的初始时，限位部410可以抵靠在连接件300上，以克服第一驱动件500的弹力，连接件300相对支架200保持不动。第一门钩100在外力的作用下，沿第一方向移动，第一钩状部120可以沿着滑动面420滑动，并能够推动限位件400相对支架200转动，限位部410也相对支架200转动。当第一钩状部120与连接件300勾合后，限位部410转动至与连接件300分离，此时限位部410不限制连接件300的旋转，连接件300可以在第一驱动件500的作用下相对支架200沿第一旋转方向转动，从而使得连接件300可以拉动第一门钩100沿第一方向移动进而关闭门体，在连接件300拉动第一门钩100的时候，缓冲件600可以提供阻尼，减慢第一门钩100的移动速度，从而减少关门的噪声。
可以理解的是，由于相关技术中门钩的拉动是依靠卡合件沿滑槽的滑动来实现，滑槽的设置需要足够的横向尺寸，导致门锁装置的横向尺寸过大。而本申请实施方式通过将拉动第一门钩100的连接件300设置为相对支架200旋转的方式，可以减小连接件300在第一方向(即横向)的运动范围，从而减小支架200部分位置处的横向尺寸，即减小支架200的面积，进而减小门锁装置的尺寸，降低其占用的空间大小。
作为连接件300的可选实现方式，连接件300包括第一支臂310和第二支臂320。
第一支臂310和第二支臂320可以通过一体加工工艺制造，第一支臂310和第二支臂320可以沿不同的方向延伸，第一支臂310的一端与第二支臂320的一端连接，且第一支臂310和第二支臂320的连接处设置有可转动连接于支架200的旋转部330，以实现连接件300相对支架200的旋转。
其中，第一支臂310可以主要用于勾合第一钩状部120，第二支臂320可以主要用于连接第一驱动件500和缓冲件600，从而简化连接件300的结构，方便加工。可选地，缓冲件600和第一驱动件500可以连接在第二支臂320背离旋转部330的末端。
第一支臂310与第二支臂320之间具有用于容纳第一钩状部120的容纳区340。另外，当第一钩状部120位于容纳区340外，限位部410抵靠于第二支臂320背离第一支臂310的外侧，当第一钩状部120移动至容纳区340内，限位部410与第二支臂320分离，第一支臂310能够在第一驱动件500的作用下勾合第一钩状部120。
可选地，参照图2，第二支臂320可以比第一支臂310长，第二支臂320背离旋转部330的末端可以向下凸出于第一支臂310，且限位部410可以抵靠于该端的外侧，使得第一钩状部120可以顺利进入容纳区340，限位部410还可以限制连接件300的转动。
在某些实施方式中，第一支臂310可以包括与支臂本体311以及勾合部312，勾合部312可转动连接于支臂本体311的一端，支臂本体311背离勾合部312的另一端连接在第二支臂320上。勾合部312用于勾合第一钩状部120。作为支臂本体311和勾合部312的一种连接方式，支臂本体311可以一体设置有销轴，勾合部312设置有销孔，销轴可以插入销孔 中，实现两者的转动连接。
图11示出了本申请实施方式的门锁装置在关门过程中，第一钩状部与勾合部接触时的状态图；图12示出了本申请实施方式的门锁装置在关门过程中，第一钩状部推动勾合部相对支臂本体旋转的状态图；图13示出了本申请实施方式的门锁装置在关门过程中，连接件拉动第一钩状部移动的状态图；图14示出了本申请实施方式的门锁装置在关门过程中，第二驱动件移动至旋转部的第二侧的状态图。图11中，勾合部312沿逆时针方向相对支臂本体311旋转的方向为第二旋转方向。第二旋转方向为矢量方向。
请参照图11至图14，关门时，第一钩状部120可以在外力的作用下沿第一方向推动勾合部312的外侧面，以使勾合部312沿第二旋转方向相对支臂本体311旋转，且在该过程中，限位件400可以始终抵靠于连接件300上，即支臂本体311相对支架200保持静止。当勾合部312旋转至预设角度后，第一钩状部120可以位于容纳区340内，此时，限位件400可以解除对连接件300的限制，勾合部312可以依靠重力恢复至其相对支臂本体311未旋转前的原位，从而跟随支臂本体311相对支架200转动，勾合部312的内侧面勾合第一钩状部120，从而拉动第一门钩100沿第一方向移动，从而关闭门体。由于勾合部312能够相对支臂本体311旋转，使得第一钩状部120更容易与连接件300勾合，且结构简单、容易实现。其中，预设角度可以根据情况设置，不做限定。
请参照图8，支臂本体311具有抵靠于勾合部312外侧面的止挡部313，止挡部313用于限制勾合部312沿与第二旋转方向相反的方向旋转。
图15示出了本申请实施方式的门锁装置在开门过程中，第一钩状部拉动连接件相对支架旋转的状态图；图16示出了本申请实施方式的门锁装置在开门过程中，第一钩状部与连接件分离的状态图。图15和图16中，直线箭头的方向是与第一方向相反的方向。
请参照图15和图16，由于止挡部313抵靠于外侧面，使得勾合部312只能相对支臂本体311沿图8中的逆时针方向旋转，而不能沿顺时针方向旋转。因此，当开门时，第一钩状部120与勾合部312的内侧面相接触，止挡部313阻挡勾合部312沿与第二旋转方向相反方向的运动，勾合部312可以相对支臂本体311保持固定，勾合部312和支臂本体311可以同时在第一门钩100的带动下相对支架200旋转，从而可以避免勾合部312沿顺时针方向旋转，提高了开门的效率，还可防止关门的过程中，第一钩状部120与连接件300分离，提高门锁装置的可靠性。
参照图3、图4和图9，作为限位件400的可选实施方式，限位件400朝向旋转部330的表面具有滑动面420，当限位部410抵靠于连接件300时(如图2所示)，限位部410设置于滑动面420沿第一方向的一端，且限位部410沿朝向旋转部330的方向凸出于滑动面420设置，从而使得限位部410可以抵靠于第二支臂320外。
可以理解，限位件400可以大致为条状结构，在图2所示的状态下，限位件400可以沿第一方向延伸，且其朝向旋转部330的部分表面构成滑动面420，限位部410可以位于限位件沿第一方向的端部，且其还可以向上凸出于滑动面420，从而可以抵靠于第二支臂320，以限制连接件300相对支架200的转动。
且滑动面420与勾合部312之间具有间隙，该间隙可以容许第一段121可以沿第一方向移动，以使得第二段122可以推动勾合部312，而当第二段122与勾合部312分离，第三段123可以推动限位件400相对支架转动，使得限位部410转动至与第二支臂320分离，从而解除对连接件300的限制。
在某些实施方式中，滑动面420可以包括第一子面421和第二子面422，当限位部410抵靠于连接件300时(如图2所示)，第一子面421沿第一方向延伸，第二子面422位于第一子面421沿第一方向的一端，且第二子面422相对第一子面421倾斜设置，并且在图2所示的状态下，第二子面422沿着第一方向逐渐向上倾斜。
参照图11至图14，在关门时，当第一钩状部120在外力作用下推动勾合部312转动时，第三段123可以沿着第一子面421滑动，由于第一子面421的延伸方向与第一钩状部120的移动方向一致，限位件400与第二支臂320保持相对位置不变化，限位部410始终抵靠于第二支臂320，而当第二段122与勾合部312分离时，第一钩状部120可以在外力的作用下沿第一方向在第二子面422上滑动，由于第二子面422为斜面，此时，第三段123推动限位件400相对支架200旋转，限位部410顺时针转动与第二支臂320分离，从而解除对连接件300的限制，此时第一驱动件500可以拉动连接件300沿第一旋转方向旋转，从而勾合并拉动第一钩状部120沿第一方向移动，以关闭门体。
参照图15和图16，在开门时，初始时刻第一子面421相对第一方向倾斜设置，限位部410位于第一门钩100下方，当拉动门体，第一钩状部120沿与第一方向相反的方向移动，从而拉动连接件300沿与第一旋转方向相反的方向旋转，当第三段123移动至与第一子面421相接触时，第三段123开始沿第一子面421滑动，从而可以拉动限位件400逆时针转动，使得限位部410恢复至能够抵靠到第二支臂320的位置上，但是此时由于第二段122还没有与勾合部312分离，在第二段 122的拉动下，第二支臂320可以转动至限位部410沿第一方向的后侧，且两者之间具有间隔，当第二段122与勾合部312分离后，连接件300在第一驱动件500的拉动下，沿第一旋转方向转动，直至第二支臂320抵靠在限位部410上，然后第一钩状部120继续移动至第三段123与第一子面421分离。
可选地，限位件400的旋转轴线位于滑动面420与旋转部330之间。例如，限位件400上可以设置有沿垂直于第一方向凸出于滑动面420的凸起430，支架200上可以设置有容纳槽240，该凸起430可以容纳于容纳槽240，并能够在容纳槽240内转动，限位件400除凸起430外的部分可以位于容纳槽240外，容纳槽240内可以具有圆柱轴，凸起430可以具有连接通孔440，连接通孔440可以套设于圆柱轴外，以实现限位件400相对支架200的旋转。
另外，参照图13，支架200上还可以设置有限位柱230，限位柱230可以位于限位件400的转动路径上，当限位件400被推动而解除对连接件300的限制后，限位件400可以转动到与限位柱230相接触，从而停止转动，限位柱230可以用于控制限位件400的转动角度，减小限位件400的转动路径。
可以理解，滑动面420除了上述方式外，其还可以有其他实现方式，例如，限位部410可以依靠弹簧抵靠于连接件300，滑动面可以为相对第一方向倾斜设置的斜坡面，当第一门钩100沿斜坡面滑动时，可以克服连接限位件的弹簧的阻力，从而推动限位部转动，以解除对连接件300的限制。而在关门时，第一门钩100也可以沿着斜坡面滑动，由于没有第一门钩100的阻挡，限位件可以在弹簧的作用下恢复至抵靠于连接件300的位置。
请参照图5及图6，支架200和连接件300之间还设置有第二驱动件700，第二驱动件700可以是螺旋弹簧，螺旋弹簧的一端可以连接在支架200上，螺旋弹簧的另一端可以连接于连接件300上。由于第二驱动件700连接于支架200和连接件300之间，当连接件300相对支架旋转时，第二驱动件700的位置也会发生变化，其会在连接件300的旋转轴线的两侧移动，从而可以提供不同方向的扭矩。
旋转部330的轴线为连接件300的旋转轴线，当连接件300沿第一旋转方向转动时，第二驱动件700能够从旋转部330的轴线的第一侧移动至第二侧，即第二驱动件700的轴线可以在旋转部330的轴线的两侧之间移动。参照图5，可以理解的是，图中用中心线示出了旋转部330的轴线以及第二驱动件700的转动中心线，经过这两个轴线的平面为A面，第一侧和第二侧分别为A面的两侧，第二驱动件700从第一侧移动至第二侧，可以理解成为第二驱动件700的两端之间的连线从A面的第一侧移动至第二侧。
参照图12，当第一钩状部120推动勾合部312时，旋转部330并未相对支架200旋转，此时，第二驱动件700可以位于旋转部330的轴线的第一侧(图中的左下侧)，此时第二驱动件700用于向连接件300提供沿与第一旋转方向相反方向的扭矩，而当第一钩状部120和勾合部312分离后，连接件300同时受到第一驱动件500和第二驱动件700提供的扭矩，第一驱动件500提供的扭矩方向为第一旋转方向，而第二驱动件700提供的扭矩方向与第一旋转方向相反。
可以理解，第一驱动件500提供的扭矩大于第二驱动件700提供的扭矩，使得连接件300可以沿第一旋转方向相对支架200旋转，但是，由于第二驱动件700提供的反向的扭矩的作用，可以减小第二支臂320与限位部410之间的作用力，使得第二支臂320更容易与限位部410相互分离。
参照图13，连接件300继续沿第一旋转方向相对支架200旋转时，第二驱动件700与连接件300连接的一端会相对支架200转动，参照图14，当第二驱动件700转动至位于旋转部330的轴线的第二侧(图中的右上侧)，第二驱动件700用于向连接件300提供沿第一旋转方向的扭矩，即第一驱动件500以及第二驱动件700向连接件300提供的扭矩方向相同，可以加速连接件300的旋转速度，快速关闭门体。
在开门过程中，连接件300沿与第一旋转方向相反的方向转动时，第二驱动件700能够从旋转部330的轴线的第二侧移动至第一侧，其所提供的扭矩方向由第一旋转方向变为与第一旋转方向相反的方向。在开门的初始时刻，第二驱动件700位于旋转部330的轴线的第二侧，第一驱动件500和第二驱动件700同时提供阻碍连接件300旋转的扭矩，继续参照图15和图16，当第一钩状部120即将与勾合部312分离时，第二驱动件700移动至旋转部330轴线的第一侧，第二驱动件700提供有利于开门的扭矩，此时，第二支臂320的末端移动至限位部410沿第一方向的后侧，两者之间具有间隔，而当第一钩状部120与勾合部312分离后，第一驱动件500拉动连接件300沿第一旋转方向转动，使得限位部410抵靠于第二支臂320的末端，第二驱动件700在该过程中提供与第一旋转方向相反的扭矩，可以减轻限位部410和第二支臂320末端的碰撞，减小开门时候的噪音。
在某些实施方式中，支架200上设置有罩设于连接件300外的罩体210，第二驱动件700位于罩体210背离连接件300的一侧，从而将连接件300和第二驱动件700相互分开，避免两者运动干涉。
罩体210设置有第一柱状体211；连接件300上设置有第二柱状体321，第二驱动件700连接在第一柱状体211和第 二柱状体321之间，以通过罩体210将第二驱动件700的端部连接于支架200上。罩体210上设置有弧形孔212，第二柱状体321穿设于弧形孔212，可以理解，弧形孔212的长度可以大于第二柱状体321的移动轨迹的长度，弧形孔212可以为第二柱状体321的移动提供避让空间，使得第二驱动件700可以跟随连接件300转动。
可选地，第二驱动件700为螺旋弹簧，其两端可以设置有弯钩，一个弯钩勾合于第一柱状体211，另一个勾合于第二柱状体321，为了提高第二驱动件700连接的可靠性，第一柱状体211和第二柱状体321上可以设置有与该弯钩卡合的卡槽。
在某些实施方式中，第一柱状体211位于连接件300背离滑动面420的一侧，第二柱状体321位于旋转部330与第二支臂320背离旋转部330的末端之间，该结构可以实现第二驱动件700在旋转部330的两侧之间移动，且可以利用连接件300的顶部空间，避免周围部件与第二驱动件700发生干涉。
继续参照图1和图2，在某些实施方式中，门锁装置还包括第二门钩800，第二门钩800包括用于与门体连接的第二安装部810以及与第二安装部810连接的第二钩状部820；支架200上设置有用于滑设第二钩状部820的坡道220。
第二安装部810可以用于与门体连接，第二安装部810与门体的连接方式可以参考第一安装部110与门体的连接方式，可选地，第二安装部810可以沿图1的上下方向滑设于门体，或者第二安装部810可以设置为能够相对于门体旋转的结构，第二安装部810与门体之间可以设置有弹性件。
坡道220相对第一方向倾斜设置；当第二钩状部820沿第一方向移动时，第二钩状部820沿着坡道220滑动，并勾合于坡道220沿第一方向的端面。同时设置第一门钩100和第二门钩800可以提高门体关闭时的可靠性，且该方式结构简单，容易实现。
进一步可选地，支架200设置有限位开关，当门体关闭后，第二钩状部820的头部可以抵靠在限位开关，限位开关被触发，从而将门体关闭的信号发送给控制器。
可以理解的是，图1中，第一门钩100位于第二门钩800的底部，在其他实施方式中，第一门钩100可以位于第二门钩800的顶部，可以根据实际情况设置。
参照图13，在关门的过程中，第一钩状部120在第一驱动件500的作用下沿第一方向移动时，第二钩状部820可以克服第二弹性件的弹力沿着坡道220滑动，且当门体关闭后，第二钩状部820卡合于坡道220的沿第一方向的端面，并与限位开关接触。
本申请实施方式提供一种家用电器，包括门体、箱体以及门锁装置；门锁装置的第一门钩100的第一安装部110连接在门体上，门锁装置的支架200连接在箱体上。
家用电器可以包括但不限于洗涤电器、烹饪器具、消毒电器等等具有门钩的家用电器，烹饪器具可以为微波炉、烤箱等设备，门体可以通过竖直铰链铰接于箱体上，门锁装置可以应用在门体和箱体背离铰接位置的一侧。门锁装置的结构和功能与上述各个实施方式相同，具体可以参考上述各个实施方式，在此不再赘述。
本申请实施方式提供的家用电器，通过设置第一门钩100、支架200、以及设置于支架200上的连接件300和限位件400；第一门钩100具有第一钩状部120，连接件300用于勾合第一钩状部120；限位件400包括滑动面420和抵靠于连接件300的限位部410。在关门时，第一门钩100能够在外力的作用下移动，并沿滑动面420滑动，以使限位件400相对支架200旋转，使得限位部410由抵靠于连接件300上的状态移动至与连接件300分离的状态，此时，连接件300能够相对支架200转动，从而拉动第一钩状部120沿第一方向移动以关闭门体。由于连接件300通过相对支架200的转动来拉动第一门钩100，可以相应减少连接件300沿第一方向的运动范围，从而减少支架200的面积，进而减小门锁装置的尺寸以及空间占用率，提高了家用电器的空间利用率。
相关技术中，诸如微波炉的烹饪器具包括门体和箱体；箱体用于盛放食物，门体铰接于箱体的一侧，门体的另一侧设置有门钩，箱体的另一侧对应地设置有勾槽，当推动门体时，门钩在推力的作用下勾合于勾槽中，从而关闭门体。
但是，相关技术中，为了使门钩能够顺利勾合于勾槽中，使用者在关闭门体时，需要施加一定的推力，门体在受到推力移动的过程中，会以一定的速度撞击箱体，从而导致关门时门体与箱体之间的噪声大，用户体验差。
为了解决上述问题中的至少一个，本申请实施方式提供一种门锁装置及家用电器，通过将门锁装置中的第一门钩设置于门体，将门锁装置中的支架设置于箱体上，支架上连接有驱动件、连接件和缓冲件。且在门体关闭的过程中，缓冲件能够减慢第一门钩相对支架的移动速度，从而降低关门时的噪声。
以下结合附图17至图33，对本申请实施方式进行详细阐述。图17示出了本申请实施方式中门锁装置的结构示意图；图18为图17的内部结构示意图；图19为图17的背视图；图20为图19中的部分结构示意图；图21为图20的爆炸示意 图；图22为图18中的部分结构示意图；图23为图22的爆炸示意图。图18中直线箭头所示的方向为第一方向，而弧形箭头所示的方向为第一旋转方向；可以理解，第一方向和第一旋转方向均为矢量方向。以第一方向为例，矢量方向可以理解成具有指向性的方向，例如图18中从左向右的方向为第一方向，而从右向左的方向为与第一方向相反的方向，连接件沿逆时针转动的方向为第一旋转方向，而连接件沿顺时针转动的方向为与第一旋转方向相反的方向。
请参照图17至图23，本实施方式提供一种门锁装置，可以用于具有门体和箱体的结构中，尤其是可以用于微波炉等家用电器中，门锁装置包括：第一门钩100、支架200、连接件300、驱动件400以及缓冲件500。
以应用于烹饪器具为例，第一门钩100可以安装于烹饪器具的门体上，连接件300、支架200、驱动件400以及缓冲件500可以安装于烹饪器具的箱体上。其中，第一门钩100包括第一安装部110以及第一钩状部120。
第一安装部110可以用于与门体连接，第一安装部110的实现方式可以有多种，可选地，第一安装部110可以包括安装螺孔，螺钉可以螺纹连接于安装螺孔，并将其螺接于门体的侧面；或可选地，第一安装部110可以包括凸起，门体上可以设置有卡槽，凸起可以卡合安装于卡槽中。
第一钩状部120可以通过焊接、螺接、铆接等工艺连接于第一安装部110上，或可选地，两者可以通过一体加工的方式加工成型。第一钩状部120可以大致沿垂直于第一方向(图18中的上下方向)延伸。且第一钩状部120可以凸出于门体，使得门体关闭后，其可以伸入箱体的一侧。
支架200可以为厚度不高的板状结构，其可以用于与箱体连接。支架200连接至箱体的方式可以有多种，例如支架200上设置多个通孔，螺钉可以穿设通孔，并将支架200通过螺母螺接于箱体上；又或者，支架200还可以通过卡扣配合的方式卡合于箱体上。
连接件300可转动地连接于支架200，连接件300上可以设置有旋转部330，旋转部330的轴线可以为连接件300相对支架200旋转的轴线，旋转部330可转动地连接于支架200，从而能够使连接件300相对支架200旋转。可以理解，旋转部330可以是转动通孔，支架200上可以设置有凸出的旋转轴，连接件300可以通过转动通孔套设于旋转轴外，从而实现连接件300的旋转。又例如，旋转部330可以为设置于连接件300上的旋转轴，支架200上可以具有转动通孔，旋转轴可以转动连接在转动通孔中。
另外，部分连接件300可以位于第一钩状部120沿第一方向移动的移动路径上，当第一钩状部120沿第一方向移动时，连接件300可以和第一钩状部120接触，使得连接件300可以在第一钩状部120的推动下相对支架200沿第一旋转方向旋转。
驱动件400可以连接在支架200和连接件300间，驱动件400可以为能够提供动力的结构，例如直线电机、液压缸、弹簧或弹力绳索等。驱动件400可以提供拉力或者推力。可选地，驱动件400为螺旋弹簧，螺旋弹簧的一端可以连接在支架200上，螺旋弹簧的另一端可以连接于连接件300上，由于驱动件400连接于支架200和连接件300之间，当连接件300相对支架200旋转时，驱动件400的位置也会发生变化，以驱动件400为螺旋弹簧为例，螺旋弹簧的轴线会在连接件300的旋转轴线的两侧移动，从而可以提供不同方向的扭矩。
因此，当连接件300在被第一钩状部120推动而沿第一旋转方向旋转时，驱动件400能够从连接件300的旋转轴线的第一侧移动至第二侧，即驱动件400的轴线可以在旋转部330的轴线的两侧之间移动。
参照图18，可以理解的是，图中用虚线示出了驱动件400连接在支架200上的端部的位置，以及连接该端部的中心与旋转部330的中心的基准连线A。第一侧和第二侧分别为基准连线A的两侧，第一侧为图18中基准连线A的左上侧，第二侧可以为图18中基准连线A的右下侧。驱动件400从第一侧移动至第二侧，可以理解成为驱动件400的两个端部之间的连线从基准连线A的第一侧移动至第二侧。
当驱动件400位于第一侧时，驱动件400用于提供阻碍连接件300沿第一旋转方向旋转的扭矩；当驱动件400位于第二侧时，驱动件400用于提供驱动连接件300沿第一旋转方向旋转的扭矩，以使连接件300勾合第一钩状部120，并拉动第一钩状部120沿第一方向移动以关闭门体。
缓冲件500连接在支架200上，缓冲件500用于减慢第一钩状部120沿第一方向移动的速度，从而减轻门体和箱体的碰撞，降低噪声。缓冲件500的结构也可以有多种，例如，缓冲件500也可以包括螺旋弹簧等弹性结构，或缓冲件500可以是阻尼器结构，例如直线阻尼器或旋转阻尼器。缓冲件500可以提供弹力阻碍第一钩状部120的移动，可以理解，当驱动件400移动至第二侧时，驱动件400提供的动力可以大于缓冲件500的阻力，使得第一钩状部120只会减缓运动速度，而并不会改变运动方向。
可选地，缓冲件500可以是单向阻尼器，当第一门钩100沿第一方向移动时，单向阻尼器可以减慢其移动速度，而当 第一门钩100沿与第一方向相反的方向移动时，单向阻尼器不提供阻尼，不会减缓第一门钩100的移动速度，从而在关门时减轻门体与箱体的碰撞，减少噪声，反之，在开门时，缓冲件500不会减缓门体开启速度，提高用户体验。
缓冲件500可以与连接件300连接，从而减缓连接件300沿第一旋转方向的转动速度，进而减缓第一钩状部120沿第一方向的移动速度。或者，缓冲件500的输出端可以设置在第一门钩100的移动路径上，当第一门钩100与缓冲件500接触后，其可以减缓第一门钩100沿第一方向的移动速度。
以驱动件400是拉簧为例，关门过程的初始时，连接件300可以相对支架200保持不动，驱动件400可以位于第一侧。第一门钩100在外力的作用下，沿第一方向移动，第一钩状部120可以推动连接件300，使得连接件300相对支架200沿第一旋转方向旋转，从而带动驱动件400的位置改变，使得其由第一侧移动至第二侧，驱动件400所提供的扭矩也从阻碍连接件300沿第一旋转方向的旋转，而改变成驱动连接件300沿第一旋转方向旋转。驱动件400可以拉动连接件300，使得第一钩状部120与连接件300相勾合，并继续驱动连接件300拉动第一门钩100沿第一方向移动，进而关闭门体。且在连接件300与第一门钩100接触后，缓冲件500可以提供阻尼，减慢第一门钩100的移动速度，从而减少关门的噪声。另外，在关门过程中，当驱动件400位于第一侧，如果操作者关门的力太小，门体则会被连接件300的反作用力弹回去，这样可以起到提示作用，提示操作者门体并未关闭。
并且，本实施方式提供的门锁装置结构简单、成本较低，且由于连接件300设置为能相对支架200旋转，但不会相对支架200沿第一方向移动的方式，从而可以减小支架200沿第一方向的纵深，使得门锁装置具有更小的占用空间，可以适用于不同容积的机型，具备较强的通用性。
参照图21，在某些实施方式中，连接件300包括用于勾合第一钩状部120的第一支臂310以及连接于第一支臂310的第二支臂320；第一支臂310和第二支臂320可以通过一体加工工艺制造。第二支臂320位于第一支臂310背离第一安装部110的一侧，第一支臂310的一端与第二支臂320的一端连接，且第一支臂310和第二支臂320的连接处可转动地连接于支架200，即第一支臂310和第二支臂320的连接处设置有可转动地连接于支架200的旋转部330。
其中，第一支臂310可以主要用于勾合第一钩状部120，驱动件400可以与第一支臂310连接，缓冲件500可以与第二支臂320连接，从而将连接件300的功能分散于第一支臂310和第二支臂320，以此简化连接件300的结构，方便加工。
参照图18，当第一钩状部位于第一支臂310背离第二支臂320外侧时，驱动件400位于第一侧，第一支臂310背离旋转部330的末端和第二支臂320背离旋转部330的末端之间具有沿垂直于第一方向的高度差，即以第一支臂310背离旋转部330的一端为第一支臂310的末端，以第二支臂320背离旋转部330的一端为第二支臂320的末端。以图18的上下方向为高度方向，第一支臂310的末端和第二支臂320的末端在该高度方向上具有高度差。
以经过连接件300的旋转轴线、且平行于第一方向的平面为基准平面，第一支臂310的末端到基准平面的距离为D1，第二支臂320的末端到基准平面的距离为D2，D1可以小于D2，D2与D1之间的差值为该高度差。
该高度差用于容许第一钩状部120沿第一方向由第一支臂310的外侧移动至第一支臂310和第二支臂320之间，并推动第二支臂320沿第一旋转方向旋转，以使第一支臂310勾合第一钩状部120。即在第一钩状部120沿第一方向移动至第一支臂310和第二支臂320之间的过程，第一钩状部120的顶端可以不与第一支臂310接触，或者与其刚好接触，第一支臂310并不会与第一钩状部120相互干涉，第一钩状部120可以顺利进入第一支臂310和第二支臂320之间。当第一钩状部120进入第一支臂310和第二支臂320之间，第一钩状部120可以继续沿第一方向移动，然后推动第二支臂320，并克服驱动件400提供的阻碍连接件300沿第一旋转方向旋转的扭矩，使得第二支臂320能够沿第一旋转方向旋转，并带动驱动件400从第一侧移动至第二侧，驱动件400可以提供驱动连接件300沿第一方向旋转的扭矩，使得第一支臂310旋转至勾合第一钩状部120，并拉动第一钩状部120沿第一方向继续移动以关闭门体。
可以理解，请参照图18，在第一钩状部120位于第一支臂310的外侧时，可以通过调整连接件300在该时刻的位置，使得第一支臂310可以相对图18的上下方向倾斜设置，第一支臂310和第二支臂320之间可以具有高度差。当第一钩状部120推动第二支臂320时，连接件300可以沿第一旋转方向旋转，该高度差逐渐减小，使得第一支臂310可以由连接件300的顶部移动至第一钩状部120的左侧，连接件300继续旋转便可勾合第一钩状部120，并拉动第一钩状部120以实现关门操作。
通过设置第一支臂310和第二支臂320之间的位置关系，可以使得第一支臂310既不会阻碍第一钩状部120进入第一支臂310和第二支臂320之间，又能够实现第一支臂310勾合第一钩状部120，并拉动第一钩状部120的作用，且可以简化连接件300的结构。
请参照图18和图19，支架200具有正面211以及与正面211相对的背面212；支架200可以为板状结构，其两个面 积较大的表面分别为正面211和背面212。
连接件300和缓冲件500位于支架200的正面211，驱动件400位于支架200的背面212，使得驱动件400可以从支架200的背面212向第一支臂310提供扭矩。
而第一门钩100可以从支架200的正面211与连接件300相勾合，使得驱动件400和第一钩状部120的运动可以被支架200隔离，不会发生干涉。
作为驱动件400和连接件300的可选连接方式，支架200上设置有连接孔213，第一支臂310上设置有穿设连接孔213的第一柱状体311，支架200的背面212设置有第二柱状体214，驱动件400的两端分别与第一柱状体311和第二柱状体214连接。
第一柱状体311可以连接在第一支臂310上，例如其可以连接在第一支臂310的末端与旋转部330之间的某处，第一柱状体311可以是圆柱状结构或者棱柱状结构等。
连接孔213的形状可以有多种，例如连接孔213可以为弧形孔或者长圆孔等，第一柱状体311可以穿过该连接孔213，并与驱动件400的一端连接。第一柱状体311可以在连接孔213中滑动，可以理解，连接孔213并未起到限定连接件300的旋转的作用，其可以容许连接件300被第一钩状部120推动，或被驱动件400驱动。
第二柱状体214可以凸出设置于支架200的背面212，其还可以与驱动件400的另一端连接。
当驱动件400为螺旋弹簧时，其两端可以分别弯曲形成钩状结构，其中一个钩状结构可以勾合在第一柱状体311的柱面，另一个钩状结构可以勾合于第二柱状体214的柱面。进一步地，第一柱状体311的柱面以及第二柱状体214的柱面都可以设置有卡槽，该卡槽可以与钩状结构的表面相卡合，从而避免驱动件400与第一柱状体311或第二柱状体214分离，提高驱动件400的连接强度。
通过设置连接孔213、第一柱状体311和第二柱状体214来安装驱动件400，可以简化连接结构，并且容易加工。
在某些实施方式中，门锁装置还包括：辅助驱动件，辅助驱动件可以位于支架200的正面211，且辅助驱动件连接于支架200与连接件300之间；且辅助驱动件和驱动件400关于支架200对称设置。
可以理解，连接件300对应第一柱状体311的位置还可以设置有第三柱状体，第三柱状体和第一柱状体311关于连接件300对称设置。支架200的正面211还可以设置有与第二柱状体214对应的第四柱状体，第二柱状体214可以与第四柱状体同轴设置，辅助驱动件也可以是螺旋弹簧，其一端与第三柱状体连接，其另一端与第四柱状体连接，即辅助驱动件和驱动件400可以同时给连接件300提供转矩，使得连接件300的两侧均设置有驱动结构，连接件300的运动平稳性好。辅助驱动件的结构和连接方式可以参考驱动件400的结构和连接方式，在此不再赘述。
可选地，参考图18和图23，支架200上设置可以有阻挡部230，阻挡部230可以凸出于支架200的正面211，当第一钩状部120位于第一支臂310背离第二支臂320的外侧时，第一支臂310可以抵靠于阻挡部230上，从而可以克服驱动件400位于第一侧时向连接件300提供的扭矩，使得连接件300保持相对支架200静止。且阻挡部230结构简单，容易加工。
当然，在某些实施方式中，也可以不设置阻挡部230，可以依靠第一柱状体311抵靠于连接孔312的孔壁，来克服驱动件400位于第一侧时向连接件300提供的扭矩。
作为第一支臂310的可选实施方式，第一支臂310上设置有沿背离第二支臂320的方向凸出的凸起部312，凸起部312用于抵靠于阻挡部230，凸起部312可以具有弧形侧面，阻挡部230也可以具有弧形侧面，凸起部312的弧形侧面可以抵靠于阻挡部230的弧形侧面，实现接触。同时，通过设置凸起部312可以合理安排连接件300的位置，合理利用门锁装置的空间。
驱动件400连接于凸起部312，可选地，第一柱状体311可以连接于凸起部312上，使得驱动件400可以跟随连接件300的旋转而在第一侧和第二侧之间移动。
参照图18、图22和图23，门锁装置还包括：连接于支架200的限位件600；限位件600能够在第一钩状部120的带动下相对支架200移动，且当第一钩状部120位于第一支臂310背离第二支臂320的外侧，限位件600位于连接件300的旋转路径上，从而限制连接件沿第一旋转方向的旋转；当第一钩状部120位于第一支臂310和第二支臂320之间，限位件600离开旋转路径，连接件300能够沿第一旋转方向旋转。
其中，限位件600相对支架200的移动方向可以有多种，例如限位件600可以相对支架200转动，或者限位件600可以相对支架200沿垂直于支架200的方向移动，其中垂直于支架200的方向可以为图18中垂直纸面的方向。
可以理解，在关门过程中，连接件300沿第一旋转方向旋转，开门时，连接件300沿与第一旋转方向相反的方向旋转。连接件300往复旋转所经过的位置称为其旋转路径。限位件600具有位于该旋转路径的第一状态、以及离开该旋转路径的 第二状态。限位件600可以第一钩状部120的带动下而在第一状态和第二状态切换。
当限位件600位于第一状态时，如图18所示，限位件600可以限制连接件300沿第一旋转方向的旋转。可以理解的是，该状态下，限位件600可以与连接件300接触或者与连接件300之间有一个较小的间隔，即两者之间无相互作用力。限位件600可以防止支架200在受到冲击和振动时，驱动件400的位置发生变化而从第一侧移动至第二侧，进而导致关门失败。即限位件600是为了防止极端工况下，连接件300在非关门过程中而沿第一旋转方向旋转的情况，提高了门锁装置的可靠性能。
当限位件600处于第二状态时，限位件600可以离开该旋转路径，连接件300可以在第一钩状部120的推动下或者驱动件400的驱动下沿第一旋转方向旋转，从而使得连接件300勾合并拉动第一钩状部120沿第一方向移动，实现关门。
在某些实施方式中，限位件600能够沿垂直于支架200的方向相对支架200移动，且限位件600具有限位部610以及导向部620。
导向部620用于将第一钩状部120沿第一方向的移动转换为限位部610相对支架200的移动，从而带动限位部610移动至位于旋转路径上或者离开旋转路径。
其中，垂直于支架200的方向可以为图18中垂直于纸面的方向。可选地，限位部610和导向部620可以依靠一体成型工艺形成一体结构。
且当第一钩状部120位于第一支臂310背离第二支臂320的外侧，限位部610可以位于第二支臂320的末端的外侧，即限位部610可以位于第二支臂320末端的旋转路径上。
当第一钩状部120位于第一支臂310和第二支臂320之间，限位部610可以离开第二支臂320的末端的旋转路径，连接件300可以被第一钩状部120推动或者被驱动件400驱动而沿第一旋转方向旋转。
可以理解，导向部620可以与第一钩状部120接触，并在第一钩状部120的带动下相对支架200移动，进而带动限位部610相对支架200移动，且当第一钩状部120位于第一支臂310的外侧，限位部610位于连接件300的旋转路径上，当第一钩状部120移动至位于第一支臂310和第二支臂320之间，限位部610可以离开该旋转路径，第一钩状部120可以继续沿第一方向移动并推动第二支臂320，使第二支臂320沿第一旋转方向旋转。限位件600相对支架200的移动可以依靠第一钩状部120沿第一方向的移动来驱动，无需设置额外的动力源，可以降低成本。
作为导向部620的一种可选的实现方式，导向部620可以具有相对于第一方向倾斜设置的导向面621；导向面621可以为平面，也可以为具有弧度的曲面。且当第一钩状部120位于第一支臂310外侧，导向面621沿垂直于支架200的方向凸出于支架200，且导向面621与支架200之间的距离沿第一方向逐渐增大。导向面621可以用于与第一钩状部120接触，将第一钩状部120的移动转换为限位部610沿垂直于支架200方向的移动，并且结构简单，容易加工。
在某些实施方式中，支架200具有用于容纳限位件600的凹槽210，限位件600能够沿垂直于支架200的方向可移动地设置于凹槽210中。限位件600与凹槽210的底壁之间设置有弹性件240，弹性件240可以提供推力，使得在开门过程中，导向部620与第一钩状部120分离后，限位部610可以在弹性件240的推动下恢复至位于连接件300的旋转路径上。
弹性件240可以是弹性块或者柱状弹簧，限位件600上可以设置有柱状体，弹性件240可以套设在柱状体外。
可选地，限位件600设置有两个相对设置的卡勾630，凹槽210的底壁具有两个第一滑动孔215，每个卡勾630穿设一个第一滑动孔215，即卡勾630可以穿出支架200。两个第一滑动孔215的尺寸可以根据卡勾630的尺寸设置，使得卡勾630可以穿设第一滑动孔215，且不会从第一滑动孔215中脱出。
弹性件240还用于向卡勾630施加抵靠于凹槽210背部的弹性力。使得当第一钩状部120与导向部620分离后，卡勾630可以勾合于凹槽210的背部，限位件600相对支架200保持固定状态。
在某些实施方式中，两个卡勾630沿第一方向相对设置，限位件600设置有两个导向柱640，两个导向柱640可以沿与第一方向垂直的方向设置，导向柱640的截面可以为方形或圆形等，其可以沿垂直于支架200的方向延伸。
凹槽210的底壁上设置有两个第二滑动孔216，每个导向柱640穿设一个第二滑动孔216，导向柱640可以在第一门钩100的带动下沿第二滑动孔216滑动，从而增加限位件600相对支架200移动的平稳性。
可选地，凹槽210的侧壁上具有容纳导向柱640的导向槽217，导向槽217的槽体可以沿垂直于支架200的方向延伸。导向柱640可以贴合导向槽217移动，进一步提高运动平稳性。
可以理解，当第一钩状体120沿导向面621移动时，其可以向导向面621施加垂直于导向面621的推力，该推力除了能够带动限位件600沿垂直于支架200的方向移动，还使得限位件600具有翻转的趋势，通过设置导向柱640和导向槽217可以提高限位件600相对支架200移动的稳定性，避免晃动。
参照图18和图19，关门时，第一钩状部120在外力作用下沿第一方向移动，第一钩状部120位于第一支臂310外侧，驱动件400位于第一侧，连接件300的凸起部312抵靠于支架200的阻挡部230，以克服驱动件400向连接件300提供的扭矩，连接件300保持静止。并且限位件600的限位部610位于第二支臂320的旋转路径上。
图24示出了本申请实施方式中的门锁装置在关门过程中，第一钩状部沿第一方向移动至和所述第二支臂相接触的状态图；图25为图24的背视图。请参照图24和图25，第一钩状部120沿第一方向移动至第一支臂310和第二支臂320之间，并且与第二支臂320恰好接触，此时第一支臂310位于第一钩状部120的左侧的顶部，驱动件400仍位于第一侧。并且限位部610恰好离开第二支臂320的旋转路径、或已经离开第二支臂320的旋转路径。
图26示出了本申请实施方式中的门锁装置在关门过程中，第一钩状部推动第二支臂沿第一旋转方向旋转的状态图；图27为图26的背视图。请参照图26和图27，第一钩状部120沿第一方向继续推动第二支臂320，此时驱动件400可以刚好跟随连接件300移动至位于第一侧和第二侧之间。第一支臂310位于第一钩状部120的左侧。缓冲件500提供阻尼，减缓连接件300沿第一旋转方向的旋转速度，进而减慢第一钩状部120沿第一方向的移动速度。
图28示出了本申请实施方式中的门锁装置在关门过程中，第一支臂勾合第一钩状部并拉动其沿第一方向移动的状态图；图29为图28的背视图。请参照图28和图29，驱动件400此时移动至第二侧，其所提供的扭矩方向发生变化，驱动件400驱动连接件300沿第一旋转方向旋转，使得第一支臂310勾合第一钩状部120，并拉动第一钩状部120沿第一方向移动。
图30示出了本申请实施方式中的门锁装置处于关门结束的状态图；图31为图30的背视图。请参照图30和图31，驱动件400驱动连接件300沿第一旋转方向旋转，继续拉动第一钩状部120移动至门体和箱体接触，关门结束。
图32示出了本申请实施方式中的门锁装置在开门过程中，第一钩状部拉动连接件沿与第一旋转方向相反的方向旋转的状态图；图33为图32的背视图。且图32中箭头的方向为与第一方向相反的方向。请参照图32和图33，在开门时，第一门钩100可以在外力的作用下沿与第一方向相反的方向移动，从而克服驱动件400的扭矩，拉动连接件300沿与第一旋转方向相反的方向旋转，驱动件400从第二侧向第一侧移动，当驱动件400移动至第一侧后，驱动件400拉动连接件300快速沿与第一旋转方向相反的方向旋转，第一支臂310跟随连接件300由第一钩状部120的左侧旋转至位于第一钩状部120上方，其便无法勾合第一钩状部120，第一钩状部120和连接件300分离，第一钩状部120可以继续移动至连接件300的外侧，实现开门过程。而连接件300可以抵靠于支架200的阻挡部230上。
且该过程中，第一钩状部120可以沿着导向面621滑动，从而使得限位部610开始沿着垂直纸面向外的方向移动，而在第一支臂310旋转至抵靠于阻挡部230之时或之前，限位部610已经移动至连接件300的旋转路径，恢复至图18所示的位置。
在某些实施方式中，门锁装置还包括第二门钩800，第二门钩800包括用于与门体连接的第二安装部810以及与第二安装部810连接的第二钩状部820；支架200上设置有用于勾合第二钩状部820的坡道220。
第二安装部810可以用于与门体连接，第二安装部810与门体的连接方式可以参考第一安装部110与门体的连接方式，可选地，第二安装部810可以沿图18的上下方向滑设于门体，或者第二安装部810可以设置为能够相对于门体旋转的结构，第二安装部810与门体之间可以设置有第二弹性件。
请参照图26，坡道220相对第一方向倾斜设置；当第二钩状部820沿第一方向移动时，第二钩状部820开始沿着坡道220滑动，并勾合于坡道220沿第一方向的端面。同时设置第一门钩100和第二门钩800可以提高门体关闭时的可靠性，且该方式结构简单，容易实现。
请参照图30，进一步可选地，支架200设置有限位开关700，其可以为常见的开关结构，限位开关700可以具有触点，当触点被按压时，其可以向控制器发出信号。
当门体关闭后，第二钩状部820的头部可以抵靠在限位开关700，限位开关700被触发，从而将门体关闭的信号发送给控制器。
可以理解的是，图18中，第一门钩100位于第二门钩800的底部，在其他实施方式中，第一门钩100可以位于第二门钩800的顶部，可以根据实际情况设置。
本实施方式还提供一种家用电器，包括门体、箱体以及门锁装置；门锁装置的第一门钩100的第一安装部110连接在门体上，门锁装置的支架200连接在箱体上。
家用电器可以包括但不限于洗涤电器、烹饪器具、消毒电器等等具有门钩的家用电器，烹饪器具可以为微波炉、烤箱等设备，门体可以通过竖直铰链铰接于箱体上，门锁装置可以应用在门体和箱体背离铰接位置的一侧。门锁装置的结构和 功能与上述各个实施方式相同，具体可以参考上述各个实施方式，在此不再赘述。
本实施方式提供的家用电器，通过设置第一门钩100、支架200、连接件300、驱动件400以及缓冲件500，第一门钩100连接于门体，且包括第一钩状部120；连接件300、驱动件400和缓冲件500连接于支架200。连接件300用于在第一钩状部120的推动下相对支架200沿第一旋转方向旋转；驱动件400连接于连接件300，当连接件300沿第一旋转方向旋转时，驱动件400能够从连接件300的旋转轴线的第一侧移动至第二侧；当驱动件400位于第一侧时，驱动件400用于提供阻碍连接件300沿第一旋转方向旋转的扭矩；当驱动件400位于第二侧时，驱动件400用于提供驱动连接件300沿第一旋转方向旋转的扭矩，以使连接件300勾合第一钩状部120，并拉动第一钩状部120沿第一方向移动以关闭门体；缓冲件500用于减慢第一钩状部120沿第一方向的移动速度，以减少门体和箱体的碰撞，降低关门噪音。
相关技术中，诸如微波炉的烹饪器具包括门体和箱体；箱体用于盛放食物，门体的一侧铰接于箱体的一侧，门体的另一侧设置有门钩，箱体的另一侧对应地设置有勾槽，当推动门体时，门钩在推力的作用下勾合于勾槽中，从而关闭门体。
但是，相关技术中，为了使门钩能够顺利勾合于勾槽中，用户在关闭门体时，需要施加一定的推力，门体在受到推力移动的过程中，会以一定的速度撞击箱体，从而导致关门时门体与箱体之间的噪声大，用户体验较差。
为了解决上述问题中的至少一个，本申请实施方式提供一种门锁装置及家用电器，通过将门锁装置中的第一门钩设置于门体，将门锁装置中的支架设置于箱体上，支架上连接有连接件、第一驱动件、第二驱动件以及缓冲件。且在门体关闭的过程中，缓冲件能够减慢第一门钩相对支架的移动速度，从而降低关门时的噪声。
以下结合附图34至图52，对本申请实施方式进行详细阐述。本申请实施方式提供一种门锁装置，该门锁装置可以应用于具有门体和箱体的装置，尤其可以应用于微波炉、烤箱等家用电器中。以微波炉为例，微波炉可以具有门体和箱体，箱体内用于盛放食物，门体可以通过垂直铰链连接在箱体上，门锁装置可以应用在门体和箱体背离铰接位置的一侧。
图34示出了本申请的一个实施方式中门锁装置的正视图；图35示出了本申请的一个实施方式中门锁装置的背视图；图36为图35的立体图；图37为图36的爆炸示意图。图34中直线箭头所示的方向为第一方向，而弧形箭头所示的方向为第一旋转方向。可以理解，第一方向和第一旋转方向均为矢量方向。以第一方向为例，矢量方向可以理解成具有指向性的方向，例如图34中从左向右的方向为第一方向，而从右向左的方向为与第一方向相反的方向，连接件沿逆时针转动的方向为第一旋转方向，而连接件沿顺时针转动的方向为与第一旋转方向相反的方向。参照图34至图37，门锁装置可以包括：设置在门体上的第一门钩100以及连接于箱体上的支架200，支架200上还连接有连接件300、第一驱动件400、第二驱动件500以及缓冲件600。
第一门钩100，包括第一钩状部120以及用于与门体连接的第一安装部110。第一安装部110可以用于与门体连接，第一安装部110的实现方式可以有多种，可选地，第一安装部110可以包括安装孔，螺钉可以穿设安装孔并螺接于门体的侧面；或可选地，第一安装部110可以包括凸起，门体上可以设置有卡槽，凸起可以卡合安装于卡槽中。
第一钩状部120可以通过焊接、螺接、铆接等工艺连接于第一安装部110上，或可选地，两者可以通过一体加工的方式加工成型。第一钩状部120可以包括第一部分和第二部分，第一部分和第二部分之间可以具有一定的角度，使得两者之间具有第一凹陷区，例如，图34中的第一钩状部120具有向下的第一凹陷区，该第一凹陷区使得第一钩状部120大致成钩状。第一钩状部120可以凸出于门体，使得门体关闭后，其可以伸入箱体的一侧。
支架200可以为厚度不高的板状结构，其可以包括连接部，连接部可以用于与箱体连接。可选地，连接部可以包括设置于支架200上的多个通孔，螺钉可以穿设通孔并螺接于箱体上；又或者，连接部还可以通过卡扣配合的方式卡合于箱体上。
支架200具有正面以及与正面相对的背面。图34示出了支架200的正面210，连接件300、第一驱动件400和缓冲件600可以位于支架200的正面。图35示出了支架200的背面220，第二驱动件500可以位于连接件300的背面。
连接件300能够相对支架200旋转，即连接件300可以绕固定轴线相对支架200转动。例如，连接件300上可以设置有转动部302，转动部302可以包括转动通孔，支架200上可以设置有凸出的转轴，连接件300可以通过转动通孔套设于转轴外，从而实现连接件300的旋转。在某些实施方式中，转动部302可以包括转动轴，支架200上可以设置有转动通孔，连接件300可以通过转动轴套设于转动通孔中，从而实现连接件300的旋转。另外，连接件300可以用于勾合第一钩状部120。在某些实施方式中，连接件300可以具有能够与第一钩状部120的第一凹陷区相配合的凸缘，从而使得在关门的过程中，连接件300可以与第一钩状部120相勾合，且当连接件300相对支架200旋转时可以拉动第一钩状部120沿第一方向移动，从而实现关门。第一方向为图34中由左向右的方向，也是图35中自右向左的方向。可以理解，第一方向仅为关 门时，第一门钩100相对支架200的移动方向，而开门时，第一门钩100是沿着与第一方向相反的方向相对支架200移动。
第一驱动件400和第二驱动件500可以为能够提供动力的结构，例如直线电机、液压缸、弹簧或弹力绳索等。第一驱动件400，连接于支架200与连接件300之间，以驱动连接件300相对支架200沿第一旋转方向旋转，从而拉动第一钩状部120沿第一方向移动，以关闭门体。第一旋转方向为图34中的逆时针方向，也是图35中的顺时针方向。
以第一驱动件400是弹簧为例，弹簧的一端可以连接在支架200上，弹簧的另一端可以连接于连接件300上，当第一钩状部120勾合住连接件300时，弹簧可以拉动连接件300相对支架200沿第一旋转方向旋转，从而拉动第一钩状部120顺着第一方向移动，门体可以朝向箱体移动，从而实现关门。第一旋转方向为图34中的逆时针方向。可以理解，第一旋转方向仅为关门时，连接件300相对支架200的旋转方向，而开门时，连接件300是沿着与第一旋转方向相反的方向相对连接件300旋转。第一驱动件400可以提供拉力或者推力。在某些可选的实施方式中驱动件可以为能提供拉力的拉簧，使得驱动件的安装位置更灵活。
第二驱动件500，连接于支架200与连接件300之间，当连接件300沿第一旋转方向旋转时，第二驱动件500能够从连接件300的旋转轴线的第一侧移动至第二侧。参照图35，可以理解的是，图中用虚线示出了第二驱动件500连接在支架200上的端部的位置，以及连接该端部的中心与转动部302的中心的基准连线A。第一侧和第二侧分别为基准连线A的两侧，第一侧为图35中基准连线A的右上侧，第二侧可以为图35中基准连线A的左下侧。第二驱动件500从第一侧移动至第二侧，可以理解成为第二驱动件500的两个端部之间的连线从基准连线A的第一侧移动至第二侧。
参照图43，此时，第二驱动件500位于第一侧，第二驱动件500可以向连接件300提供与第一旋转方向相反的扭矩。参照图49，此时，第二驱动件500位于第二侧，第二驱动件500可以向连接件300提供与第一旋转方向相同的扭矩。
在关门时，当第二驱动件500转动至位于第二侧，第二驱动件500用于向连接件300提供沿第一旋转方向的扭矩，即第一驱动件400以及第二驱动件500向连接件300提供的扭矩方向相同，可以加速连接件300的旋转速度，快速关闭门体。
在开门过程中，连接件300沿与第一旋转方向相反的方向转动时，第二驱动件500能够从第二侧移动至第一侧，其所提供的扭矩方向由第一旋转方向变为与第一旋转方向相反的方向。
缓冲件600连接在支架200上，缓冲件600用于减慢第一钩状部120沿第一方向的移动速度。可选地，缓冲件600可以连接在连接件300上，从而减慢连接件300相对支架200的旋转速度，进而减慢关门时第一钩状部120沿第一方向的移动速度。或可选地，缓冲件600还可以不与连接件300连接，其可以设置于第一钩状部120的移动路径上，当第一钩状部120沿第一方向关门时，缓冲件600可以抵靠在第一钩状部120上，从而产生与第一方向相反的阻力，并减慢第一钩状部120的移动速度。
缓冲件600连接在支架200与连接件300之间，缓冲件600用于减慢第一钩状部120沿第一方向移动的速度，从而减轻门体和箱体的碰撞，降低噪声。缓冲件600的结构也可以有多种，例如，缓冲件600也可以包括螺旋弹簧等弹性结构，或缓冲件600可以是阻尼器结构，例如直线阻尼器或旋转阻尼器。缓冲件600可以提供弹力阻碍第一钩状部120的移动，可以理解，第一驱动件500提供的动力可以大于缓冲件600的阻力，使得第一钩状部120只会减缓运动速度，而并不会改变运动方向。
缓冲件600可以是单向阻尼器，当第一门钩100沿第一方向移动时，单向阻尼器可以减慢其移动速度，而当第一门钩100沿与第一方向相反的方向移动时，单向阻尼器不提供阻尼，不会减缓第一门钩100的移动速度，从而在关门时减轻门体与箱体的碰撞，减少噪声，反之，在开门时，缓冲件600不会减缓门体开启速度，提高用户体验。
在某些实施方式中，连接件300包括第一支臂310以及连接于第一支臂310的第二支臂320；第一支臂310和第二支臂320可以通过一体加工工艺制造，第一支臂310和第二支臂320可以沿不同的方向延伸，第一支臂310和第二支臂320的连接处可转动地设置于支架200上。例如，第一支臂310和第二支臂320的连接处可以设置有转动部302，转动部302的轴线可以为连接件300的旋转轴线。
转动部302可以为转动通孔，支架200上可以设置有凸出的转轴，第一支臂310和第二支臂320可以通过转动通孔套设于转轴外，从而实现其相对支架200的旋转。
其中，第一支臂310可以主要用于与第一钩状部120配合并连接第一驱动件400，第二支臂320可以主要用于连接第二驱动件500和缓冲件600，从而简化连接件300的结构，方便加工。
如图37所示，支架200上设置有第一滑动孔230，第一支臂310的末端设置有穿设第一滑动孔230的第一立柱311，支架200的背面设置有第二立柱221，第二驱动件500的两端分别与第一立柱311和第二立柱221连接，从而将第二驱动件500和第一驱动件400分别设置于支架200的两侧，避免运动干涉。
第一滑动孔230包括第一圆弧孔，且第一圆弧孔的延伸长度大于或等于第一立柱311的移动路径，可以理解，第一圆弧孔的长度可以为圆弧线的长度，第一圆弧孔的长度大于第一立柱311的移动轨迹的长度，从而使得第一圆弧孔可以为第一立柱301的移动提供避让空间，使得第二驱动件500可以跟随连接件300转动，使得第一滑动孔230不会限制第一立柱311的旋转，进而不会限制与第一立柱311相连接的连接件300的旋转。
图38示出了本申请另一个实施方式中门锁装置的正视图；图39为图38的局部放大图；图40为图39的爆炸示意图。如图38至图40所示，在某些实施方式中，门锁装置还包括第三驱动件700，连接于连接件300和支架200之间。当连接件300沿第一旋转方向旋转时，第三驱动件700能够从连接件300的旋转轴线的第三侧移动至第四侧。参照图38，可以理解的是，图中用虚线示出了第三驱动件700连接在支架200上的端部的位置，以及连接该端部的中心与转动部302的中心的基准连线B。第三侧和第四侧分别为基准连线B的两侧，第三侧为图38中基准连线B的左下侧，第四侧可以为图38中基准连线B的右上侧。第三驱动件700从第三侧移动至第四侧，可以理解成为第三驱动件700的两个端部之间的连线从基准连线B的第三侧移动至第四侧。
参照图42，此时，第三驱动件700位于第三侧，第三驱动件700可以向连接件300提供与第一旋转方向相反的扭矩。参照图48，此时，第三驱动件700位于第四侧，第三驱动件700可以向连接件300提供与第一旋转方向相同的扭矩。
在关门时，当第三驱动件700转动至位于第四侧，第三驱动件700用于向连接件300提供沿第一旋转方向的扭矩，即第一驱动件400以及第三驱动件700向连接件300提供的扭矩方向相同，可以加速连接件300的旋转速度，快速关闭门体。
在开门过程中，连接件300沿与第一旋转方向相反的方向转动时，第三驱动件700能够从第四侧移动至第三侧，其所提供的扭矩方向由第一旋转方向变为与第一旋转方向相反的方向。
参考图38至图40，为了保护连接件300，在某些实施方式中，支架200上还可以设置有位于连接件300背离支架200一侧的罩体800，罩体800设置有第三立柱810；连接件300上设置有第四立柱301，罩体800上设置有第二滑动孔820，第四立柱301穿设于第二滑动孔820；第三驱动件700位于罩体800背离连接件300的一侧，且第三驱动件700连接在第三立柱810和第四立柱301之间。
可选的，罩体800可以为多种形状。如图38所示，罩体800可以为三角形。
罩体800可以将第二驱动件500和第一驱动件400分别设置于支架200的两侧，避免运动干涉。
继续参考图38至图40，第三立柱810位于连接件300背离第一钩状部120的一侧，第四立柱301位于转动部302与第二支臂320背离转动部302的末端之间，可以实现第三驱动件700在连接件的旋转轴线的两侧之间移动，且可以利用连接件300的顶部空间，避免周围部件与第三驱动件700发生干涉。
第二滑动孔820包括第二圆弧孔，且第二圆弧孔的延伸长度大于或等于第四立柱301的移动路径。可以理解，第二圆弧孔的长度可以为圆弧线的长度，第二圆弧孔的长度大于第四立柱301的移动轨迹的长度，从而使得第二圆弧孔可以为第四立柱301的移动提供避让空间，使得第三驱动件700可以跟随连接件300转动，由此，第一滑动孔可以不限制第四立柱301的旋转，即不限制连接于第四立柱301上的第三驱动件700和连接件300的运动。
根据一些实施方式，为了保护缓冲件600，支架200上还设置有罩设于缓冲件600外的缓冲件罩620，缓冲件罩620和支架200之间围合成腔体。
可选地，缓冲件600包括直线阻尼器610，直线阻尼器610具有阻尼器本体以及能够沿直线方向相对阻尼器本体伸缩的输出端612；直线阻尼器本体可转动地设置在腔体内，输出端612穿设于腔体外，且输出端612与第二支臂320连接。
直线阻尼器610用于减慢第一钩状部120沿第一方向的移动速度。当第一钩状部120沿与第一方向相反的方向移动时，直线阻尼器610并不提供阻尼，即直线阻尼器610仅在关门时提供阻尼，而在开门时，并不提供阻尼，减少了开门的阻力。
如图34所示，当第一钩状部位于第一支臂310背离第二支臂320的外侧时，第一支臂310背离转动部302的末端和第二支臂320背离转动部302的末端之间具有沿垂直于第一方向的高度差，高度差用于容许第一钩状部120沿第一方向由第一支臂310的外侧移动至第一支臂310和第二支臂320之间，并推动第二支臂320沿第一旋转方向旋转，以使第一支臂310勾合第一钩状部120。
以经过连接件300的旋转轴线、且平行于第一方向的平面为基准平面，第一支臂310的末端到基准平面的距离为D1，第二支臂320的末端到基准平面的距离为D2，D1可以小于D2，D2与D1之间的差值为该高度差，该高度差用于容许第一钩状部120沿第一方向由第一支臂310背离第二支臂320的外侧移动至第一支臂310和第二支臂320之间，即在第一钩状部120沿第一方向移动至第一支臂310和第二支臂320之间的过程，第一钩状部120的顶端可以不与第一支臂310接触，或者与其刚好接触，第一支臂310并不会与第一钩状部120相互干涉，第一钩状部120可以顺利进入第一支臂310和第二 支臂320之间。
可以理解，参照图34，可以通过调整连接件300在该时刻的位置，使得第一支臂310和第二支臂320可以相对图34的上下方向倾斜设置，第一支臂310和第二支臂320之间可以具有高度差。而当连接件300在第一驱动件400的驱动下，连接件300沿第一旋转方向旋转，该高度差逐渐减小，使得第一支臂310可以由连接件300的顶部移动至第一钩状部120的左侧，连接件300继续旋转便可勾合第一钩状部120，并拉动第一钩状部120以实现关门操作。
当第一钩状部120位于第一支臂310背离第二支臂320的外侧时，第一立柱311抵靠于第一滑动孔230的孔壁，以使连接件在此位置上保持平衡。
当门体受到外力作用朝向箱体移动时，第一钩状部120相对支架200沿着第一方向移动，当其移动至连接件300的位置时，第一钩状部120与连接件300勾合，第一驱动件400、第二驱动件500、第三驱动件700产生的合力矩拉动连接件300相对支架200旋转，进而拉动第一钩状部120继续沿第一方向移动，而缓冲件600可以提供阻尼，减慢第一钩状部120沿第一方向的移动速度，从而减轻门体撞击箱体的速度，减少门体与箱体的冲击碰撞，进而降低关门时的噪声。
并且，本实施方式提供的门锁装置结构简单、成本较低，且由于连接件300设置为能相对支架200旋转，但不会相对支架200沿第一方向移动的方式，从而可以减小支架200沿第一方向的纵深，使得门锁装置具有更小的结构占用空间，可以适用于不同容积的机型，具备较强的通用性。
图41示出了图35中的门锁装置在关门过程中，第一钩状部运动至与连接件的第二支臂相接触时的状态图；图42为图41的隐藏了部分罩体的示意图；图43为图41的背视图；图44示出了图35中的门锁装置在关门过程中，第一支臂推动第一钩状部相对本体移动的状态图；图45为图44的隐藏了部分罩体的示意图；图46为图44的背视图；图47示出了图35中的门锁装置在开门过程中，第一钩状部推动第一支臂使连接件相对支架旋转的状态图；图48为图47的隐藏了部分罩体的示意图；图49为图47的背视图；图50示出了图35中的门锁装置在开门过程中，连接件相对支架转动至第二支臂与第一钩状部接触时的状态图；图51为图50的隐藏了部分罩体的示意图；图52为图50的背视图。
参照图41、图42、图43和图44、图45、图46，在关门过程中，起始时刻，第一钩状部120位于第一支臂310背离第二支臂320的外侧。用户关门时，在门体上施加一个沿第一方向的推力，由于第一钩状部120通过第一安装部110与门体连接，第一钩状部120也受到沿第一方向的推力。由于第一支臂310背离转动部302的末端和第二支臂320背离转动部302的末端之间具有沿垂直于第一方向的高度差，如图41、图42和图43所示，第一钩状部120可以沿第一方向由第一支臂310的外侧移动至第一支臂310和第二支臂320之间，并沿第一方向运动，之后接触到第二支臂320，并推动第二支臂320沿第一旋转方向旋转。第一钩状部120与连接件300运动一段时间后，如图44、图45和图46所示，第一支臂310勾合第一钩状部120。此时第一驱动件400提供使连接件沿第一方向旋转的力矩，以使连接件300推动第一门钩120沿第一方向运动；缓冲件600对连接件300提供一个沿第一方向的反方向的力，使第一门钩120不会移动过快，从而减小关门噪声。同时，当第二驱动件500在连接件300的第一侧时，提供阻碍连接件300沿第一旋转方向旋转的力矩，第三驱动件700在连接件300的第三侧时，提供阻碍连接件300沿第一旋转方向旋转的力矩，以使连接件300的旋转速度不过快，进而使第一门钩120沿第一方向运动的速度不过快；而当旋转件300沿第一旋转方向运动一段位移之后，第二驱动件500旋转至连接件300的第二侧时，提供使连接件300沿第一旋转方向旋转的力矩，第三驱动件700旋转至连接件300的第四侧时，提供使连接件300沿第一旋转方向旋转的力矩。由于此时缓冲件600的阻尼力已经足够大，第一驱动件400、第二驱动件500、第三驱动件700、缓冲件600的合力矩为使连接件沿第一旋转方向缓速旋转的力矩，以使第一门钩120在脱离用户的推力后仍能保持缓速向第一方向运动。
参照图47、图48、图49和图50、图51、图52，在开门过程中，起始时刻，第一钩状部120位于第一支臂310与第二支臂320中间。用户开门时，在门体上施加一个沿第一方向的反方向的拉力，由于第一钩状部120通过第一安装部110与门体连接，第一钩状部120也受到沿第一方向的反方向的拉力。如图47、图48和图49所示，第一钩状部120可以沿第一方向的反方向运动，直至与第一钩状部120勾合，此时，第一驱动件400提供使连接件沿第一方向旋转的力矩，第二驱动件500位于连接件300的第二侧，提供使连接件300沿第一旋转方向旋转的力矩，第三驱动件700位于连接件300的第四侧，提供使连接件300沿第一旋转方向旋转的力矩，以减慢连接件300沿第一旋转方向反方向旋转的速度，进而减慢第一钩状部120沿第一方向反方向运动的速度。如图50、图51和图52所示，而当旋转件300沿第一旋转方向反方向运动一段位移之后，第二驱动件500旋转至连接件300的第一侧时，提供使连接件300沿第一旋转方向反方向旋转的力矩，第三驱动件700旋转至连接件300的第四侧时，提供使连接件300沿第一旋转方向反方向旋转的力矩，第一驱动件400、第二驱动件500、第三驱动件700的合力矩为使连接件沿第一旋转方向反方向旋转的力矩，以使第一门钩120在脱离用户的拉 力后仍能向第一方向反方向运动，进而实现开门动作。可选地，在开门过程中，缓冲件600不提供阻尼力。不会影响门体开启的速度。
继续参照图34和图35，在某些实施方式中，门锁装置还包括第二门钩900，第二门钩900包括用于与门体连接的第二安装部910以及与第二安装部910连接的第二钩状部920；支架200上设置有用于勾合第二钩状部920的配合部。第二安装部910可以用于与门体连接，第二安装部910与门体的连接方式可以参考第一安装部110与门体的连接方式，在此不再赘述。
第二钩状部920可以通过焊接、螺接、铆接等工艺连接于第二安装部910上，可选地，两者可以通过一体加工的方式加工成型。第二钩状部也可以包括第一部分和第二部分，第一部分和第二部分之间可以具有一定的角度，使得两者之间具有第二凹陷区，例如，图34中的第二钩状部具有向上的第二凹陷区，该第二凹陷区使得第二钩状部大致成钩状。第二钩状部可以凸出于门体，使得门体关闭后，其可以伸入箱体的一侧。
可选地，第二钩状部的结构与第一钩状部120相同，两者可以相对设置，配合部也可以与连接件300的结构相同，使得第一钩状部120与连接件300之间的连接方式和第二钩状部920与配合部之间的连接方式相同。
或可选地，参照图34，配合部包括设置于支架200上的坡道；坡道相对第一方向倾斜设置；当第二钩状部沿第一方向移动时，第二钩状部沿着坡道滑动，并勾合于坡道沿第一方向的端面。同时设置第一门钩100和第二门钩900可以提高门体关闭时的可靠性，且该方式结构简单，容易实现。
可以理解的是，图34中，第一门钩100位于第二门钩900的底部，在其他实施方式中，第一门钩100可以位于第二门钩900的顶部，可以根据实际情况设置。
本申请实施方式还提供一种家用电器，包括门体、箱体以及门锁装置；门锁装置的第一门钩100的第一安装部110连接在门体上，门锁装置的支架200连接在箱体上。
家用电器可以包括但不限于洗涤电器、烹饪器具、消毒电器等等具有门钩的家用电器，烹饪器具可以为微波炉、烤箱等设备，门体可以通过竖直铰链铰接于箱体上。通过将门锁装置的第一门钩100的第一安装部110连接在门体上背离铰接位置的一侧，以及将门锁装置的支架200连接在箱体上背离铰接位置的一侧，可以将门锁装置应用于门体和箱体背离铰接位置的一侧。门锁装置的结构和功能与上述各个实施方式相同，具体可以参考上述各个实施方式，在此不再赘述。
本实施方式提供的家用电器，通过设置门锁装置，并将连接件300、第一驱动件400、第二驱动件500以及缓冲件600设置在支架200上；第一驱动件400能够驱动连接件300相对支架200沿第一旋转方向旋转，从而拉动第一钩状部120沿第一方向移动以关闭门体；当第二驱动件500位于第一侧时，第二驱动件500可以向连接件300提供与第一旋转方向相反的扭矩；当第二驱动件500位于第二侧时，第二驱动件500可以向连接件300提供与第一旋转方向相同的扭矩；缓冲件600，连接于支架200之间，可以减慢第一钩状部120沿第一方向的移动速度。从而减轻了门体与箱体之间的冲击碰撞，降低了关门时的噪声。并且，当家用电器为微波炉时，由于门锁装置无需在门体上开设大量孔洞，其可以在减少关门噪声的同时降低微波炉漏波的风险，提高微波炉的安全性。
目前，带有门体的家用电器可以实现用户存储物品、烹饪食物等功能，用户可通过开门和关门实现物品的取放。开关门的整个过程中，靠人力或门体惯性驱动，无缓冲设计，关门噪音与人手关门的力度强相关。因此，当用户较大力关门时，会造成关门噪音急剧增大，严重影响用户体验。
以下结合附图53至图66，对本申请实施方式进行详细阐述。
请参图53至图55，本申请实施方式的一种开关门机构100，包括：
用于安装在家用电器门体200的门钩；
用于安装在家用电器腔体的支架102；
阻尼组件104，安装在支架102，阻尼组件104包括旋转阻尼器106及转换结构108，转换结构108连接旋转阻尼器106，阻尼组件104被配置为在门钩向转换结构108施加作用力的情况下，使转换结构108带动旋转阻尼器106转动，并向门钩提供先加速再减速的作用力。
上述开关门机构100中，在门钩向转换结构108施加作用力的情况下，转换结构108可带动旋转阻尼器106转动，阻尼组件104可向门钩提供先加速再减速的作用力，进而可实现门体的缓关门/软关门，避免造成关门噪音急剧增大而影响用户体验。
具体地，家用电器可包括腔体和门体200，门体200转动地连接腔体的一侧，例如，连接在腔体前板202的左侧或右 侧，形成侧开门式的家用电器。本申请实施方式的开关门机构100可应用于侧开门式的家用电器，支架102可固定在腔体前板202。侧开门式的家用电器包括但不限于微波炉、烤箱(包括电烤箱、微波烤箱和微蒸烤一体机)、蒸箱、洗碗机、消毒柜等具有门体200的家用电器。腔体内开设有腔室，用于存储物品或食物。家用电器可以对放置在腔室内的物品进行清洗、存储、消毒、烹饪等操作。
门钩的具体数量是可以根据实际需要来设定，例如门钩的数量可以是单个，可以是两个、或多于两个。在本申请的实施方式中，门钩包括两个门钩，即上门钩110和下门钩112。
具体地，在本申请实施方式中，上门钩110通过门钩弹性件114连接门体200，下门钩112固定在门体200。在门体200关闭过程中，下门钩112与转换结构108相对，阻尼组件104被配置为在下门钩112向转换结构108施加作用力的情况下，使转换结构108带动旋转阻尼器106转动，阻尼组件104并向下门钩112提供先加速再减速的作用力。在图示的实施方式中，下门钩112可向转换结构108施加压力。
由于阻尼组件104可向下门钩112提供先加速再减速的作用力，使得在加速阶段，门体200可以依靠转换结构108的作用力去关闭，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，旋转阻尼器106可为双向阻尼器，即在顺时针和逆时针方向均起到阻尼减速的作用，可以理解，在其它实施方式中，旋转阻尼器106也可为单向阻尼器，在关门过程中，提供阻尼力即可。
另外，在其它实施方式中，下门钩112可通过门钩弹性件114连接门体200，上门钩110固定在门体200，在门体200关闭过程中，上门钩110与转换结构108相对，阻尼组件104被配置为在上门钩110向转换结构108施加作用力的情况下，使转换结构108带动旋转阻尼器106转动，并向上门钩110提供先加速再减速的作用力。
以方便说明，本申请以下实施方式以上门钩110通过门钩弹性件114连接门体200，下门钩112固定在门体200的第一情况进行说明。本领域技术人员可以参考第一情况对下门钩112可通过门钩弹性件114连接门体200，上门钩110固定在门体200的第二情况进行理解实施，本申请不对第二情况进行详细展开。
在一个例子中，门钩弹性件114可为弹簧，在本实施方式中，上门钩110由门钩弹簧连接，限位是通过门体200钣金通孔和钣金折弯结构导向限位，下门钩112固定安装到门体200上，限位是通过门体200钣金折弯结构限位导向。如此，可以避免上门钩110和下门钩112出现位置偏差而造成配合不良。
相较于将上门钩和下门钩连接成一整体，本申请实施方式的上门钩110通过门钩弹性件114连接门体200，下门钩112固定在门体200的好处是，一方面，在关门过程中，可以允许上门钩110能够沿门体200向上移动一距离，易于门体200的关闭，而且通过门钩弹性件114，可以实现上门钩110的复位，另一方面，固定的下门钩112与转换结构108相抵接时，可以向转换结构108提供较为稳定的作用力，避免下门钩112位置变动而引起额外的分力，影响关门的顺畅度及使得结构变形。
在某些实施方式中，支架102开设有上通孔116，上通孔116的下侧壁沿竖直面向支架102内部向上倾斜，用于导引上门钩110向上运动。如此，可以导引上门钩110卡设在支架102。
具体地，在门体200关闭过程中，上门钩110在门体200带动下沿着上通孔116的下侧壁开始向上运动，此时，门钩弹性件114被拉伸。在门体200继续关闭的过程中，上门钩110运动到上通孔116下侧壁的右侧，被拉伸的门钩弹性件114将上门钩110复位，上门钩110卡在上通孔116下侧壁的右侧，实现上门钩110与腔体的锁定。另外，支架102上还安装有开关件118(如微动开关)，当上门钩110卡在上通孔116的下侧壁右侧时，上门钩110的底部触发开关件118(如图66所示)，使开关件118输出关门信号。家用电器的控制器接收到关门信号，可以确定门体200关闭到位。只有在门体200关闭到位的情况下，控制器才可以控制家用电器进行工作，避免产生某些意外，例如微波漏泄，蒸汽漏泄等意外，保证了家用电器的使用安全。
较佳地，下门钩112较上门钩110更凸出于门体200，一方面，当下门钩112进入腔体并被转换结构108加速时，门体200同样被加速，而同时带动上门钩110进入上通孔116，实现联锁。另一方面，在下门钩112进入腔体时至与转换结构108抵接时这段时间内，上门钩110还没进入腔体，可减少关门阻力。
在某些实施方式中，支架102开设有下通孔120，下门钩112穿设下通孔120向转换结构108施加作用力。如此，可以使下门钩112对转换结构108施加作用力。
具体地，下通孔120的内径尺寸应能使下门钩112自由地进出，避免与下门钩112发生物理干涉，保证开关门的顺畅度。
在某些实施方式中，请参图53、图56、图58和图59，转换结构108包括：
压件122，转动地连接支架102；
转动件124，转动地连接支架102，在门钩与压件122分离的情况下，转动件124由压件122进行限位；
驱动件126，连接旋转阻尼器106，在门钩与压件122分离的情况下，驱动件126由转动件124进行限位。如此，可以将门钩的平移运动转换为旋转运动。
具体地，在图示的实施方式中，在关门过程中，下门钩112与转换结构108相对，在下门钩112与压件122分离的情况下，转动件124由压件122进行限位，在下门钩112与压件122分离的情况下，驱动件126由转动件124进行限位。
压件122和转动件124均可通过转轴转动安装在支架102。下门钩112与压件122分离的情况下，转动件124由压件122进行限位，可以理解为，转动件124被压件122限制而无法自由转动，或转动件124保持静止。在下门钩112与压件122分离的情况下，驱动件126由转动件124进行限位，可以理解为，驱动件126被转动件124限制而无法自由转动，或驱动件126保持静止。也就是说，在下门钩112还没对压件122施加作用力时，压件122对转动件124进行限位，转动件124对驱动件126进行限位，最终使得转动件124和驱动件126保持静止。在一个例子中，压件122可为压杆。
在某些和方式中，转换结构108还包括第一弹性件128，第一弹性件128连接支架102和驱动件126。如此，第一弹性件128可以向驱动件126施加入作用力，对下门钩112加速运动。
具体地，第一弹性件128用于向驱动件126提供一作用力以使驱动件126具有转动趋势，转动趋势可用于加速下门钩112。请参图57，驱动件126包括间隔的第一驱动臂130和第二驱动臂132，第二驱动臂132较第一驱动臂130更靠近门体200(门钩)方向，相对于驱动件126的转动轴，第二驱动臂132较第一驱动臂130更长。第一驱动臂130与第二驱动臂132之间形成大致呈U型的间隔134。
第一弹性件128的一端连接第一驱动臂130，第一弹性件128的另一端装配至支架102定位柱上。在驱动件126的初始状态下(即下门钩112还没与转换结构108接触)，第一弹性件128处于拉伸状态，向第一驱动臂130施加一拉力。在图示的实施方式中，第一弹性件128为拉簧。
在关门过程中，下门钩112可伸入第一驱动臂130和第二驱动臂132之间的间隔134，U型的间隔134使得下门钩112伸入时较为顺畅。第二驱动臂132卡设下门钩112，在第一弹性件128的拉力作用下，驱动件126逆时针转动，通过第二驱动臂132拉动下门钩112，进而可以使得下门钩112加速。在图示的实施方式中，驱动件126可为驱动杠杆。
可以理解，在其它实施方式中，第一弹性件128可以连接驱动件126的其它部位。第一弹性件128也可以处于压缩状态，向驱动件126提供一推力。
在某些实施方式中，驱动件126包括间隔的第一驱动臂130和第二驱动臂132，第一弹性件128连接第一驱动臂130；
转动件124包括第一转动臂136，第一转动臂136抵持第二驱动臂132。如此，可以使得驱动件126在转动件124的限位下和第一弹性件128的作用下处于力系平衡状态。
具体地，请结合图54和图57，第二驱动臂132的末端朝支架102方向延伸有一圆柱138，该圆柱138抵持第一转动臂136的上侧面，第一弹性件128向第一驱动臂130施加一拉力，使驱动件126具有逆时针转动的趋势。由于第一转动臂136通过圆柱138对第二驱动臂132进行抵持限位，使得驱动件126置于最左侧，此时力系平衡，转换结构108静止。在图示的实施方式中，转动件124可为转动杠杆。
在某些实施方式中，转动件124包括第二转动臂140，压件122通过第二转动臂140对转动件124进行限位。如此，可以使得压件122对转动件124形成限位。
具体地，压件122一侧端部具有一弯钩142，弯钩142压住转动件124的第二转动臂140端部的圆柱144，使转动件124有一个转动限位的趋势。在关门过程中，下门钩112可以向压件122施加一作用力(压力)，使得压件122转动以解除对转动件124的限位，进而解除对驱动件126的限位，使得驱动件126能够转动，驱动件126在第一弹性件128作用下通过第二驱动臂132带动下门钩112进行加速。
在某些实施方式中，转动件124包括第三转动臂146，在驱动件126驱动第三转动臂146运动的情况下，转动件124被带动使得压件122形成对第二转动臂140的限位。如此，可以使得压件122重新对转动件124形成限位。
具体地，在门体200关闭到位的情况下，压件122没有对转动件124进行限位。在门体200打开过程中，驱动件126沿关门时转动方向的反方向转动，通过第三转动臂146带动转动件124同样沿反方向转动，最终使得压件122重新形成对第二转动臂140的限位，进而实现对转动件124的重新限位。
在某些实施方式中，转换结构108还包括第二弹性件148，第二弹性件148连接支架102和压件122的一端，压件122的另一端卡设第二转动臂140。如此，第二弹性件148可以向压件122施加一作用力，使得转动件124具有一转动趋势。
具体地，第二弹性件148用于向压件122提供一作用力以使压件122具有转动趋势，转动趋势用于使转动件124转动以对驱动件126形成限位。
在图示的实施方式，第二弹性件148可为压簧，第二弹性件148与第二转动臂140位于压件122所在转轴的两侧，第二弹性件148向压件122提供一推力，使得压件122具有逆时针转动的趋势。具有逆时针转动的趋势的压件122向转动件124提供一作用力，使得转动件124也具有一逆时针转动的趋势。
可以理解，在其它实施方式中，第二弹性件148也可以向压件122提供一拉力。
在某些实施方式中，请参图60和图61，驱动件126开设有结合孔150，结合孔150的孔壁设有第一齿部152，旋转阻尼器106包括穿设结合孔150的转轴，转轴外壁设有与第一齿部152相结合的第二齿部154。如此，可以使得驱动件126与旋转阻尼器106之间的结合紧密。
具体地，在图示的实施方式中，第一齿部152沿结合孔150的孔壁360度连续设置，第二齿部154沿转轴外周面360度连续设置，进一步提升结合紧密度。可以理解，在其它实施方式中，第一齿部152也可沿结合孔150的孔壁360度间隔设置，第二齿部154的设置方式与第一齿部152的设置方式相同或不同。
以下说明下本申请实施方式的开关门机构100的原理过程。
在初始时刻(请结合图62，下门钩112还没有与转换结构108抵接)，第二弹性件148处于压缩状态，由于第二弹性件148具有恢复形变的趋势，所以，第二弹性件148对压件122有一个反弹力(推力)，使压件122有一个逆时针转动的趋势，压件122左侧端部的弯钩142压住转动件124的第二转动臂140端部的圆柱144，使转动件124有一个逆时针转动限位的趋势，转动件124的第一转动臂136与驱动件126的第二驱动臂132的端部的圆柱138抵接。由于第一弹性件128的作用，使驱动件126具有一个逆时针转动的趋势，而转动件124的第一转动臂136限位左右，使驱动件126置于最左侧，此时平面力系平衡，结构静止。在平面力系下，支架102变形较小，避免在相关技术中，存在垂直于支架102的第三个方向的力系，使得支架102变形比较大。
(一)缓关门/软关门开关门机构100的关门过程：(顺逆时针的判定，以图53为正面视角参照)
1)如图62-图66所示，下门钩112在一定的初速度或一定的惯性力作用条件下，最先经过驱动件126的第二驱动臂132的左侧端部，两者有一定的间隙无干涉，下门钩112在进入腔体的过程中，最先接触的是压件122的顶部，下门钩112右侧端部的下表面对压件122的顶部有一个下压的作用，带动压杆顺时针转动，压件122的顺时针转动会使转动件124的第二转动臂140端部圆柱144脱离压件122左侧弯钩142，转动件124顺时针转动，对驱动件126的限位作用消失，驱动件126在第一弹性件128的作用下发生逆时针转动，由于第一弹性件128的初始拉伸量较大，提供了较大拉力，驱动件126在该较大拉力下，沿逆时针转动，从而带动下门钩112慢慢加速进入腔体内部，实现加速阶段。在这个过程，第一弹性件128的拉伸量在减少，提供的拉力也在减少。特别的，下门钩112在加速进入腔体过程时，旋转阻尼器106有一个顺时针的阻尼力，当旋转阻尼器106提供顺时针的阻尼力大于第一弹性件128提供的拉力时，驱动件126的运动状态由加速到减速，下门钩112也由加速到减速，同时下门钩112联动门体200也是先加速再减速，旋转阻尼器106发生阻尼减速作用，在门体200关闭到位时，可减少噪音。
2)关门到位的瞬间，驱动件126到达最右侧位置，门体200关闭到位。
3)在关门过程中，上门钩110在下门钩112带动下进入腔休并沿着上通孔116的下侧壁(导向结构)开始向上运动，直至上门钩110运动到上通孔116的下侧壁的右侧，上门钩110被卡住，下门钩112被驱动件126卡住到最右侧，实现联锁。
(二)缓关门/软关门机构的开门过程：(关门过程的逆运动)
1)人力驱动下，上门钩110运动至上通孔116的下侧壁顶端，下门钩112同步运动，此时下门钩112开始与驱动件126接触，驱动件126顺时针转动，旋转阻尼器106顺时针有阻尼转动，驱动件126的第二驱动臂132端部圆柱138压住转动件124的第一转动臂136，在驱动件126顺时针转动过程中第二驱动臂132的端部圆柱138触碰转动件124的第三转动臂146，使转动件124发生逆时针转动，同时转动件124的第二转动臂140的端部圆柱144逆时针转动进入压件122左侧弯钩142位置，压件122对驱动件126形成限位，下门钩112脱离驱动件126。阻尼组件104再次达到力系平衡。
2)人力驱动下，下门钩112带动驱动件126顺时针转动，同时上门钩110沿着上通孔116的下侧壁滑动并脱离，门体200打开。
本申请实施方式还提供一种家用电器，其包括：
腔体；
门体200，转动地连接在腔体的一侧；
上述任一实施方式的开关门机构100，支架102安装在腔体，门钩安装在门体200。
上述家用电器中，在门钩向转换结构108施加作用力的情况下，转换结构108可带动旋转阻尼器106转动，阻尼组件104可向门钩提供先加速再减速的作用力，进而可实现门体的缓关门/软关门，避免造成关门噪音急剧增大而影响用户体验。
需要说明的是，上述对开关门机构100的实施方式和有益效果的解释说明，也适应用于本实施方式的家用电器，为避免冗余，在此不再详细展开。
在相关技术中，家用电器可包括主体和门体，主体内设有腔室，门体转动地连接主体以打开或关闭腔室。腔室内可供用户存储物品、烹饪食物等操作。用户存储物品、烹饪食物时，打开门体，并将物品、食物放置入腔室内，之后关闭门体。然而，在门体的打开和关闭过程中，依靠用户作用力或门体的惯性，没有缓冲设计。若门体的关闭速度过大时，会导致关门的噪音增大，给用户体验带来不良影响。
以下结合附图67至图79，对本申请实施方式进行详细阐述。
请参图67至图69，本申请实施方式的一种联锁机构100，包括：
用于安装在家用电器门体200的门钩；
用于安装在家用电器腔体的支架102；
阻尼组件104，安装在支架102，阻尼组件104包括直线式阻尼器106及转换结构108，转换结构108包括转动连接直线式阻尼器106的驱动件109，在门钩向转换结构108施加作用力的情况下，转换结构108使门钩向上移动与驱动件109连接使得驱动件109带动门钩加速并压缩直线式阻尼器106，直线式阻尼器106被压缩时向门钩提供阻尼并发生转动。
上述联锁机构100中，在门钩向转换结构108施加作用力的情况下，阻尼组件104可带动直线式阻尼器106转动并向门钩提供先加速再减速的作用力，进而可实现门体200的缓关门/软关门，避免造成关门噪音急剧增大而影响用户体验。
具体地，家用电器可包括门体200和腔体，门体200可转动地连接腔体的一侧，例如，连接在腔体前板202的左侧或右侧，形成侧开门式的家用电器。本申请实施方式的联锁机构100可应用于侧开门式的家用电器，支架102可固定在腔体前板202。侧开门式的家用电器包括但不限于微波炉、烤箱(包括电烤箱、微波烤箱和微蒸烤一体机)、蒸箱、洗碗机、消毒柜等具有门体200的家用电器。腔体内开设有腔室，用于存储物品或食物。家用电器可以对放置在腔室内的物品进行清洗、存储、消毒、烹饪等操作。
门钩的具体数量是可以根据实际需要来设定，例如门钩的数量可以是单个，可以是两个、或多于两个。在本申请的实施方式中，门钩包括两个门钩，即第一门钩110和第二门钩112。在图示的实施方式中，第一门钩110为上门钩，第二门钩112为下门钩。
在本申请实施方式中，第一门钩110通过第一门钩弹性件114连接门体200，第二门钩112通过第二门钩弹性件115连接门体200。在门体200关闭过程中，第二门钩112可与转换结构108相对，在第二门钩112向转换结构108施加作用力的情况下，转换结构108使第二门钩112向上移动与驱动件109连接使得驱动件109带动第二门钩112加速并压缩直线式阻尼器106，直线式阻尼器106被压缩时向门钩提供阻尼并发生转动。
具体地，第一门钩110的左侧具有第一挂钩，第一门钩弹性件114的一端勾住第一挂钩，另一端勾住门体的第二挂钩。第一门钩弹性件114的初始状态可以是自然状态，即没有被接伸状态，也可以是受到一定作用力的拉抻状态，在此不作具体限定。
第二门钩112的左侧具有第三挂钩，第二门钩弹性件115的一端勾住第三挂钩，另一端勾住门体的第四挂钩。第二门钩弹性件115的初始状态可以是自然状态，即没有被接伸状态，也可以是受到一定作用力的拉抻状态，在此不作具体限定。
由于驱动件109可带动第二门钩112加速，使得在加速阶段，门体200可以依靠驱动件109的作用力去关闭。而在第二门钩112加速过程中，直线式阻尼器106的压缩量增大，提供的阻尼力也在增大，当直线式阻尼器106提供的阻尼力大于驱动件109提供的作用力时，第二门钩112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，直线式阻尼器106被压缩时，可以转动，可配合第二门钩112向上移动的方式，使得第二门钩112进入腔体时更顺畅。在图示的实施方式中，支架102上还安装有阻尼器盖117，阻尼器盖117内设置有容置空间。请结合图68，直线式阻尼器106包括粗杆部119和细杆部121，细杆部121可伸缩地连接粗杆部119，粗杆部119收容在容置空间，并转动连接在容置空间的内部，直线式阻尼器106可以绕粗杆部119与容置空间内部的连接外转动。细杆部121伸出阻尼器盖117并与驱动件109转动连接。
以方便说明，本申请以下实施方式以第一门钩110为上门钩，第二门钩112为下门钩的第一情况进行说明。本领域技术人员可以参考第一情况对第一门钩110为下门钩，第二门钩112为上门钩的第二情况进行理解实施，本申请实施方式不对第二情况进行详细展开。
在一个例子中，第一门钩弹性件114和第二门钩弹性件115可为均弹簧，在本实施方式中，第一门钩110和第二门钩112均由门钩弹簧连接，限位是通过门体200钣金通孔和钣金折弯结构导向限位，如此，可以避免第一门钩110和第二门钩112出现位置偏差而造成配合不良。
相较于将第一门钩110和第二门钩112连接成一整体，本申请实施方式的第一门钩110和第二门钩112通过门钩弹性件连接门体200的好处是，在关门过程中，可以允许第一门钩110和第二门钩112能够沿门体200向上移动一距离，易于门体200的关闭，而且通过门钩弹性件，可以实现第一门钩110和第二门钩112的复位。
在某些实施方式中，支架102开设有第一导向孔116，第一导向孔116的下侧壁沿竖直面向支架102内部向上倾斜，用于导引第一门钩110向上运动。如此，可以导引第一门钩110卡设在支架102。
具体地，在门体200关闭过程中，第一门钩110在门体200带动下沿着第一导向孔116的下侧壁开始向上运动，此时，第一门钩弹性件114被拉伸。在门体200继续关闭的过程中，第一门钩110运动到第一导向孔116下侧壁的右侧，被拉伸的第一门钩弹性件114将第一门钩110复位，第一门钩110卡在第一导向孔116下侧壁的右侧，实现第一门钩110与腔体的锁定。另外，支架102上还安装有开关件118(如微动开关)，当第一门钩110卡在第一导向孔116的下侧壁右侧时，第一门钩110的底部触发开关件118(如图79所示)，使开关件118输出关门信号。家用电器的控制器接收到关门信号，可以确定门体200关闭到位。只有在门体200关闭到位的情况下，控制器才可以控制家用电器进行工作，避免产生某些意外，例如微波漏泄，蒸汽漏泄等意外，保证了家用电器的使用安全。
较佳地，第二门钩112较第一门钩110更凸出于门体200，一方面，当第二门钩112进入腔体并被驱动件109加速时，门体200同样被加速，同时带动第一门钩110进入第一导向孔116，实现联锁。另一方面，在第二门钩112进入腔体时至与转换结构108抵接时这段时间内，第一门钩110还没进入腔体，可减少关门阻力。
在本实施方式中，第一门钩110与第二门钩112的钩子方向是相对的，这样可以减少门钩在竖直方向上的整体的长度，相应地，也可减少支架102在竖直方向上的整体长度。
在某些实施方式中，支架102开设有第二导向孔120，第二门钩112穿设第二导向孔120向转换结构108施加作用力。如此，可以使第二门钩112对转换结构108施加作用力。
具体地，第二导向孔120的内径尺寸应能使第二门钩112自由地进出，避免与第二门钩112发生物理干涉，保证开关门的顺畅度。
在某些实施方式中，第一门钩110包括第一本体123和第一转动销125，第一转动销125转动连接第一本体123，和，第二门钩112包括第二本体127和第二转动销129，第二转动销129转动连接第二本体127。如此，第一门钩110(上门钩)的转动销可以使第一门钩110更灵活。第二门钩112(下门钩)的转动销可以使触碰驱动件109比较灵活，接触时转动销有旋转，相比于无转动销能减少碰撞异音。
具体地，第一转动销125与第一导向孔116的下侧壁抵接时，第一转动销125转动，可以减少第一门钩110弹性件的伸长量，减少开关门的阻力。在第一转动销125跨过第一导向孔116的下侧壁右侧时，第一转动销125复位。第一本体123下侧面还设有钩部136，第一门钩110继续向腔体侧运动时，钩部136能够卡住第一导向孔116下侧壁的右侧。
具体地，请参图72，沿靠近腔体的方向，钩部136和第一转动销125依次排列，第一转动销125转动连接在钩部136的右侧。第一转动销125较钩部136更凸设于第一本体123的下侧面。钩部136大致呈V形，最低端为圆角结构，可以使得钩部136跨过第一导向孔116下侧壁的右侧时阻力更少，运动更顺畅。当钩部136的最底端跨过第一导向孔116下侧壁的右侧时，第一门钩弹性件114向下拉动第一本体123，进而带动钩部136也向下运动，钩部136的左侧卡设在第一导向孔116下侧壁的右侧，使得腔体卡住第一门钩110。
在关门过程中，第二转动销129与驱动件109抵接，第二转动销129转动，一方面，也可减少第二门钩弹性件115的拉伸量，减少开关门的阻力，另一方面，转动的转动销也可以卸掉一部分两者抵接时的作用力，减少第二门钩112与驱动件109碰撞异音。
在图示的实施方式中，第一门钩110弹性件连接门体和第一本体123，第二门钩弹性件115连接门体和第二本体127。
可以理解，在其它实施方式中，第一门钩110包括第一本体123和第一转动销125，第一转动销125转动连接第一本体123，或，第二门钩112包括第二本体127和第二转动销129，第二转动销129转动连接第二本体127。
在某些实施方式中，请参图67至图71，转换结构108包括：
限位结构122，安装在支架102，在门钩与限位结构122分离的情况下，驱动件109由限位结构122进行限位，在门钩抵接限位结构122且限位结构122解除驱动件109的限位的情况下，驱动件109能够带动门钩加速；
导向件124，安装在支架102，导向件124用于使门钩向上移动。如此，可以实现对驱动件109的限位和解除限位，及对门钩的导向上移。
具体地，在图示的实施方式中，在关门过程中，第二门钩112与转换结构108相对，导向件124用于使第二门钩112向上移动，在第二门钩112与限位结构122分离的情况下，驱动件109由限位结构122进行限位，在第二门钩112抵接限位结构122且限位结构122解除驱动件109的限位的情况下，驱动件109能够带动第二门钩112加速。
导向件124可固定在支架102上，在图示的实施方式中，导向件124呈板状，且斜向上安装在支架102。在关门过程中，当第二门钩112滑进导向件124时，斜向上的导向件124将第二门钩112向上抬升，特别是完全关上门时，可以保证驱动件109勾住第二门钩112端部，卡紧门体。
在第二门钩112与限位结构122分离的情况下，驱动件109由限位结构122进行限位，可以理解为，驱动件109被限位结构122限制而无法自由转动，或驱动件109保持静止。在第二门钩112抵接限位结构122的情况下，限位结构122解除驱动件109的限位以使得驱动件109能够带动门钩加速，可以理解为，限位结构122对驱动件109的限位解除，使得驱动件109在作用力下能够转动来带动门钩加速。
在某些和方式中，转换结构108还包括第一弹性件128，第一弹性件128连接支架102和驱动件109。如此，第一弹性件128可以向驱动件109施加作用力，使得驱动件109可以对第二门钩112加速。
具体地，第一弹性件128用于向驱动件109提供一作用力以使驱动件109具有转动趋势，转动趋势可用于加速第二门钩112。请参图68，驱动件109包括间隔的第一臂130和第二臂132，第二臂132较第一臂130更靠近门体200(门钩)方向，相对于驱动件109的转动轴，第二臂132较第一臂130短。第一臂130与第二臂132之间形成大致呈U型的间隔134。
第一弹性件128的一端连接第一臂130，第一弹性件128的另一端装配至支架102定位柱上。在驱动件109的初始状态下(即第二门钩112还没与转换结构108接触)，第一弹性件128处于拉伸状态，向第一臂130施加一拉力。在图示的实施方式中，第一弹性件128为拉簧。
在关门过程中，第二门钩112可先解除限位结构122对驱动件109的限位，之后第二转动销129可伸入第一臂130和第二臂132之间的间隔134，第二转动销129的一侧与第一臂抵接时转动(图示的逆时针转动)，并推动驱动件109逆时针转动，使得第二臂132与第二转动销129另一侧抵接并使第二转动销129复位，进而使得第二臂卡设第二门钩112。在第一弹性件128的拉力作用下，驱动件109逆时针转动，通过第二臂132拉动第二门钩112，进而可以使得第二门钩112加速。在图示的实施方式中，驱动件109可为驱动杠杆。
可以理解，在其它实施方式中，第一弹性件128可以连接驱动件109的其它部位。第一弹性件128也可以处于压缩状态，向驱动件109提供一推力。
在某些实施方式中，驱动件109包括间隔的第一臂130和第二臂132，第一弹性件128连接第一臂130；
请参图69，限位结构122包括可活动的限位凸起131，限位结构122通过限位凸起131对第二臂132进行限位。如此，驱动件109可以使得驱动件109在限位凸起131的限位下和第一弹性件128的作用下处于力系平衡状态。
具体地，请结合图68至图69，限位凸起131沿垂直于支架102方向伸入间隔134中，并抵持第二臂132的右侧而形成限位，第一弹性件128向第一臂130施加一拉力，使驱动件109具有逆时针转动的趋势。由于限位凸起131对第二臂132进行抵持限位，使得驱动件109置于最左侧，此时力系平衡，转换结构108静止。
在某些实施方式中，限位结构122包括导向凸起133，在门体关闭过程中，门钩驱动导向凸起133以带动限位凸起131解除第二臂132的限位。如此，在关门过程中，门钩可以解除限位结构122对驱动件109的限位。
具体地，导向凸起133具有一导向斜面，在关门过程中，第二门钩112最先接触到的是导向凸起133，第二门钩112在导向斜面上滑动，第二门钩112对导向凸起133有一个挤压作用，被挤压的导向凸起133可带动限位凸起131沿同一方向运动，使限位凸起131移出间隔134，解除对第二臂132的限位，进而解除驱动件109的限位。
在某些实施方式中，限位结构122包括支撑板135及第二弹性件137，支撑板135包括相背的第一面和第二面，导向凸起133和限位凸起131设置在第一面，第二弹性件137连接第二面和支架102。如此，可以使得导向凸起133带动限位凸起131运动。
具体地，导向凸起133与限位凸起131间隔设置在支撑板135的同一面，第二弹性件137设置在支撑板的另一面，第 二弹性件137用于向支撑板135提供一推力，使得限位凸起131保持对第二臂的限位。当第二门钩112挤压导向凸起133时，被挤压的导向凸起133通过支撑板135带动限位凸起131向支架102方向移动，进而使限位凸起131移出间隔134，解除对驱动件109的限位。在开门过程中，第二门钩112脱离导向凸起133后，第二弹性件137通过支撑板驱动限位凸起131复位，重新形成对驱动件109的限位。在图示的实施方式中，第二弹性件137为压簧。可以理解，在其它实施方式中，第二弹性件137可以对支撑板135提供一拉力，使限位凸起131复位。
在图示的实施方式中，限位结构122通过支撑板135两侧的卡扣与支架102进行安装。限位凸起131可为圆柱。具体地，支撑板135的两侧分别设有一卡扣，支架102上开设有一安装空间，安装空间的底部两边分别开设有一卡孔。装配时，先将第二弹性件137装配于安装空间的底部，并定位。然后，将带有导向凸起133和限位凸起131的支撑板135向安装空间安装，使卡扣与卡孔对准，卡扣卡入卡孔，支撑板135将第二弹性件137压缩于安装空间内。装配完成。
向支撑板135、导向凸起133和限位凸起131中的任一者施加一压力，可以使得支撑板135、导向凸起133和限位凸起131整体地向支架102方向移动，第二弹性件137被进一步压缩。压力撤消后，第二弹性件137对支撑板135、导向凸起133和限位凸起131进行复位。
在某些实施方式中，直线式阻尼器106包括连接杆，连接杆的端部与第一臂转动连接。如此，可以实现驱动件109与直线式阻尼器106的转动连接。
具体地，连接杆可为直线式阻尼器106的细杆部121或粗杆部119，在图示的实施方式中，连接杆为直线式阻尼器106的细杆部121。
第一臂130开设有连接孔139，该连接孔139大致呈圆柱形，连接孔侧面设有开口，供连接杆穿过。连接杆的端部连接有圆柱部141，圆柱部141与连接孔配合连接，实现转动连接。圆柱部141可以与连接杆一体结构或分体结构，圆柱部141与连接杆一体结构时，可以采用相同材料，也可以采用不同材料。在此不作具体限定。
可以理解，在其它实施方式中，连接孔139的形状还可以是其它形状，例如呈圆球形，连接杆端部的形状与连接孔的形状相匹配即可，即使呈球形。在此不作具体限定。
以下说明下本申请实施方式的联锁机构100的原理过程。
初始时刻(第二门钩112还没有与转换结构108抵接，如图74)，驱动件109在限位结构122构作用下静止，第一弹性件被拉长到最大，第一弹性件拉力最大，且直线式阻尼器106伸长量最大，从图74看，第一弹性件使驱动件109有逆时针转动的趋势，而此时，限位结构122构的限位凸起131使驱动件109无法逆时针旋转，驱动件109实现力系平衡。此时为平面力系平衡，结构静止。在平面力系下，支架102变形较小，避免在相关技术中，存在垂直于支架102的第三个方向的力系，使得支架102变形比较大。
(一)缓关门/软关门开闭件机构的关门过程：(顺逆时针的判定，以图67为正面视角)
1)如图74至图79所示，第二门钩112在一定的初速度或一定的惯性力作用条件下，最先经过驱动件109的左侧端部(即第二臂左侧端部)，两者有一定的间隙无干涉，第二门钩112在进入腔体的过程中，最先接触的是限位结构122的导向凸起133，第二门钩112对导向凸起133有一个挤压作用，导向凸起133在挤压作用力下带动限位凸起131发生垂直于支架102的位移，当限位凸起131与驱动件109脱离时，驱动件109在第一弹性件的拉力下，发生逆时针旋转，驱动件109的逆时针旋转，将第二门钩112加速带入至腔体内部。特别的，第二门钩112在加速进入腔体过程时，直线式阻尼器106产生阻尼力，驱动件109的运动状态由加速到减速，同时第二门钩112联动门体也是先加速再减速，直线式阻尼器106发生阻尼减速作用，并同时整体转动以适应驱动件109的转动。第二门钩112的初速度或一定的惯性力可以是用户关门时向门体200施加，进而施加至第二门钩112上而形成的
2)关门的瞬间，驱动件109到达最右侧位置，门体200关闭到位。
3)在关门过程中，第一门钩110在第二门钩112进入腔体带动下沿着第一导向孔的下侧壁开始向上运动，直至第一门钩110运动到第一导向孔的下侧壁的右侧，第二门钩112被驱动件109卡住到最右侧。门体200关闭到位。
4)在关门整个过程中，第一门钩110和第二转动销129均能发生一定的旋转，起到柔性接触及缓冲冲击作用。
(二)缓关门/软关门机构的开门过程：(关门过程的逆运动)
1)人力驱动下，第一门钩110运动至第一导向孔的下侧壁顶端，第一转动销125会发生逆时针的转动，第二门钩112同步运动，此时第二门钩112开始与驱动件109的第二臂接触，驱动件109顺时针转动，在开门的整个过程中，第二门钩112内侧一直压着导向凸起133，当第二门钩112内侧与导向凸起133发生脱离时，限位凸起131与驱动件109的第二臂右侧接触，起到限位的作用，此时门体被打开，阻尼组件104达到力系平衡。人力可以是用户通过门体的把手向外拉门而 形成。
2)人力驱动下，第二门钩112带动驱动件109顺时针转动，同时第一门钩110沿着第一导向孔滑动并脱离，门体打开。
本申请实施方式还提供一种家用电器，其包括：
腔体；
门体200，转动地连接在腔体的一侧；
上述任一实施方式的联锁机构100，支架102安装在腔体，门钩安装在门体200。
上述家用电器中，在门钩向转换结构108施加作用力的情况下，阻尼组件104可带动直线式阻尼器106转动并向门钩提供先加速再减速的作用力，进而可实现门体200的缓关门/软关门，避免造成关门噪音急剧增大而影响用户体验。
具体地，家用电器包括但不限于微波炉、烤箱(包括电烤箱、微波烤箱和微蒸烤一体机)、蒸箱、洗碗机、消毒柜等具有门体200的家用电器。需要说明的是，上述对联锁机构100的实施方式和有益效果的解释说明，也适应用于本实施方式的家用电器，为避免冗余，在此不再详细展开。
在相关技术中，家用电器可包括腔体和门体，腔体内设有腔室，门体转动地连接腔体以打开或关闭腔室。在门体的打开和关闭过程中，依靠用户作用力或门体的惯性，若门体的关闭速度过大，会导致关门的噪音增大。为解决关门噪音较大的问题，通常采用的方案是缓关门机构，缓关门机构可以在关门时提供一阻尼力以减少关门速度，进而降低关门噪音。然而，在相关技术中，缓关门机构在门钩抵接时即提供了一定的阻尼力，易造成门钩出现回弹现象，造成关门不顺畅甚至停滞现象。
以下结合附图80至图97，对本申请实施方式进行详细阐述。
请参图80至图86，本申请实施方式的一种开关门组件100，包括门钩、支架102、阻尼组件104。阻尼组件104安装在支架102，阻尼组件104包括阻尼器106、摆动件108和驱动件110，摆动件108转动连接驱动件110和阻尼器106，在门钩向驱动件110施加作用力的情况下，驱动件110转动一预设角度后带动摆动件108压缩阻尼器106，阻尼器106被压缩时向门钩提供阻尼并发生转动。
上述开关门组件100中，在门钩向驱动件110施加作用力的情况下，驱动件110可先转动一预设角度后带动摆动件108压缩阻尼器106，进而可实现在门钩作用于驱动件110初期时，门钩不至于被阻尼器106回弹而造成关门不顺畅甚至停滞现象，提升了用户体验。
具体地，阻尼器106通过摆动件108与驱动件110转动连接，实现了分体式的转动连接，即摆动件108与驱动件110转动连接，摆动件108与阻尼器106转动连接，驱动件110带动摆动件108转动时，具有预设角度的间隔，使得门钩与驱动件110抵接时，阻尼器106并未产生阻尼作用。避免关门不顺畅甚至停滞现象。
开关门组件100可用于家用电器，家用电器包括但不限于洗碗机、微波炉、蒸箱、烤箱(包括电烤箱、微波烤箱和微蒸烤一体机)、消毒柜等家用电器。家用电器可包括门体200和腔体，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，形成侧开门式的家用电器。本申请实施方式的开关门组件100可应用于侧开门式的家用电器，支架102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。家用电器可以对放置在腔室内的物品进行清洗、存储、消毒、烹饪等操作。门体200可以采用多层玻璃的门体，如双层玻璃的门体。采用玻璃门体的其中一个好处是方便用户在外面观察腔体内的食物情况。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。家用电器还包括腔体外的壳体，壳体可以保护家用电器内的电气件及结构件，同时也避免对用户造成伤害。
驱动件110可通过支架102上的转轴转动连接在支架102上，在一个例子中，驱动件110可以为驱动杠杆。门钩可安装在门体200，用于在关门时勾住腔体侧的驱动件110，以实现关门。较佳地，门钩的材料可选自金属，如铁、铝、不锈钢及合金等。门钩整体呈长度状，末端设有钩状部，以卡设于腔体。门钩数量可根据实际情况来设定，如，门钩的数量可以是单个、两个、或多于两个。在本申请的实施方式中，门钩包括两个门钩，即第一门钩112和第二门钩114。在图80所示的实施方式中，第一门钩112为上门钩，第二门钩114为下门钩。
在本申请实施方式中，第一门钩112通过门钩弹性件116连接门体200，第二门钩114固定在门体200。在门体200关闭过程中，第二门钩114可与阻尼组件104相对，在第二门钩114向驱动件110施加作用力的情况下，驱动件110转动一预设角度后带动摆动件108压缩阻尼器106，阻尼器106被压缩时向门钩提供阻尼并发生转动。
相较于将两个门钩均通过门钩弹性件连接门体，本申请实施方式的第一门钩112通过门钩弹性件116连接门体200， 第二门钩114固定在门体200的好处是，一方面，在关门过程中，可以允许第一门钩112能够沿门体200向上移动一距离，易于门体200的关闭，而且通过门钩弹性件116，可以实现第一门钩112的复位，另一方面，固定的第二门钩114与驱动件110相抵接时，可以向驱动件110提供较为稳定的作用力，避免第二门钩114位置变动而引起额外的分力，影响关门的顺畅度及使得结构变形。而且，相较于将两个门钩连接成一整体，本申请实施方式的第一门钩112通过门钩弹性件116连接门体200，第二门钩114固定在门体200的好处是可以避免第一门钩112和第二门钩114的相互影响。
以方便说明，本申请以下实施方式以第一门钩112为上门钩，第二门钩114为下门钩的第一情况进行说明。本领域技术人员可以参考第一情况对第一门钩112为下门钩，第二门钩114为上门钩的第二情况进行理解实施，本申请实施方式不对第二情况进行详细展开。
在一个例子中，门钩弹性件116为弹簧，在本实施方式中，第一门钩112由门钩弹簧连接，限位是通过门体200钣金通孔和钣金折弯结构导向限位，第二门钩114固定安装到门体200上，限位是通过门体200钣金折弯结构限位导向。如此，可以避免第一门钩112和第二门钩114出现位置偏差而造成配合不良。
在某些实施方式中，支架102的两个侧面均设有加强筋，以增加支架的结构强度，提升开关门组件100的稳定性和可靠性。支架102呈上部小，下部大的形状，可以减少重量，减少空间占用及节省材料，支架102的下部主要是安装阻尼组件104，使得下部的重量占比较大，支架102的整体重心较低，有利于保持支架102的稳定。
在某些实施方式中，支架102开设有第一孔118，第一孔118的下侧壁沿竖直面向支架102内部向上倾斜，用于导引第一门钩112向上运动。如此，可以导引第一门钩112卡设在支架102。
具体地，在门体200关闭过程中，第一门钩112在门体200带动下沿着第一孔118的下侧壁开始向上运动，此时，门钩弹性件116被拉伸。在门体200继续关闭的过程中，第一门钩112运动到第一孔118下侧壁的右侧，被拉伸的门钩弹性件116将第一门钩112复位，第一门钩112卡在第一孔118下侧壁的右侧，实现第一门钩112与腔体的锁定。另外，支架102上还安装有开关件120(如微动开关)，当第一门钩112卡在第一孔118的下侧壁右侧时，第一门钩112的底部触发开关件120(如图94所示)，使开关件120输出关门信号。家用电器的控制器接收到关门信号，可以确定门体200关闭到位。只有在门体200关闭到位的情况下，控制器才可以控制家用电器进行工作，避免产生某些意外，例如微波漏泄，蒸汽漏泄等意外，保证了家用电器的使用安全。例如，家用电器为侧开门式微波炉。微波炉工作时会向腔体内中馈入微波进行食物烹饪。若在门体200未关闭的情况下工作，腔体内的微波会泄漏出去，对用户造成伤害。因此，门体200关闭到位时，开关件120被第一门钩112触发，生成关门信号，控制器才能控制微波炉馈入微波至腔体内。又如，家用电器为蒸炉。蒸炉工作时会出腔体内输送高温蒸汽进行食物烹饪，若在门体200未关闭的情况下工作，腔体内的高温蒸汽会泄漏出去，对用户造成烫伤。因此，门体200关闭到位时，开关件120被第一门钩112触发，生成关门信号，控制器才能控制蒸炉产生高温蒸汽至腔体内。另外，在用户触发家用电器工作时，若门体200未关闭到位(即控制器没接收到关门信号)，家用电器可发出警报，提示用户将门体200关闭到位后才触发家用电器工作。
较佳地，第二门钩114较第一门钩112更凸出于门体200，一方面，当第二门钩114进入腔体并作用于驱动件110时，门体200同样被带动靠近腔体，并同时带动第一门钩112进入第一孔118，实现联锁。另一方面，在第二门钩114进入腔体时至与驱动件110抵接时这段时间内，第一门钩112还没进入腔体，可减少关门阻力。
在某些实施方式中，支架102开设有第二孔122，第二门钩114穿设第二孔122向驱动件110施加作用力。如此，可以使第二门钩114对驱动件110施加作用力。
具体地，第二孔122的内径尺寸应能使第二门钩114自由地进出，避免与第二门钩114发生物理干涉，保证开关门的顺畅度。
在图80所示的实施方式中，阻尼器106为直线式阻尼器。可以理解，在其它实施方式中，阻尼器106还可以其它阻尼器106，例如旋转阻尼器。
在某些实施方式中，请参图83及图85，驱动件110开设有容置槽124，容置槽124的顶部开设转动空间126，容置槽124的底部开设有摆动空间128，摆动件108的一端转动收容在转动空间126，摆动件108的另一端收容在摆动空间128，摆动空间128用于提供驱动件110转动预设角度的空间。如此，可以使得驱动件110在转过预设角度后再带动摆动件108转动。
具体地，请参图83，驱动件110包括间隔的第一臂130和第二臂132，第一臂130和第二臂132之间形成有大致呈U型的间隔134，第二臂132较第一臂130更靠近门体200(门钩)方向，相对于驱动件110的转轴，第二臂132较第一臂130更短。
第一臂130开设有容置槽124，具体是，在图示的实施方式中，第一臂130的右侧开设有容置槽124，摆动件108位于容置槽124中。
摆动件108的顶端具有一连接转动部136，连接转动部136转动地收容在转动空间126。在一个例子中，转动空间126大致呈圆柱形，连接转动部136呈与转动空间126相匹配的圆柱形。
摆动空间128的设置可以使得驱动件110刚开始转动时，不会作用于摆动件108，进而不会压缩阻尼器106，使得门钩在抵接驱动件110初期，不会受到阻尼器106的阻力而引起回弹甚至停滞现象。摆动空间128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。
进一步地，摆动空间128的右侧设有凸起138，该凸起138用于将摆动件108限定在容置槽124内，避免摆动件108脱离容置槽124。
在某些实施方式中，驱动件110包括间隔的第一臂130和第二臂132，第一臂130开设有容置槽124，在门钩向驱动件110运动的情况下，门钩从第二臂132下方经过后与第一臂130抵接以驱动驱动件110转动。如此，可以使得门钩驱动驱动件110转动后，第二臂132能够勾住门钩来带动门钩关门。
具体地，在关门时，第二门钩114在一定初速度或惯性下进入腔体，先从第二臂132下方经过，两者没干涉，之后，第二门钩114抵接第一臂130，使得驱动件110转动，此时，转动的驱动件110使得第二臂132也同样转动，第二臂132的右侧与门钩左侧抵接，使得转动的驱动件110通过第二臂132能够带动门钩继续关门动作。
在图示的实施方式中，第一臂130和第二臂132基本上整体地位于驱动件110转轴沿竖直方向的一侧，如此，可以使得第一臂130能够及早与第二门钩114抵接而发生转动。第一臂130的末端向门钩方向凸出。
在某些实施方式中，阻尼组件104包括弹性件，弹性件和驱动件110位于支架102的相背两侧，请参图82和图84，支架102开设有通孔140，驱动件110通过通孔140连接弹性件，弹性件用于带动驱动件110加速转动以使驱动件110带动门钩加速。如此，可以实现门钩的先加速，再减速的过程。
具体地，位于支架102相背两侧的弹性件和驱动件110，可以将相关结构件分散布置，避免在支架102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。
弹性件可以向驱动件110提供拉力以使驱动件110带动门钩加速，也可以向驱动件110提供推力以使驱动件110带动门钩加速。在图示的实施方式中，弹性件向驱动件110提供拉力以使驱动件110带动门钩加速。
由于驱动件110可带动第二门钩114加速，使得在加速阶段，门体200可以依靠驱动件110的作用力去关闭。而在第二门钩114加速过程中，当驱动件110转动预设角度后，阻尼器106被压缩。随着关门过程的继续，摆动件108持续压缩阻尼器106，阻尼器106的压缩量增大，提供的阻尼力也在增大，当阻尼器106提供的阻尼力大于驱动件110提供的驱动力时，第二门钩114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106被压缩时，可以转动，可配合转动件和摆动件108转动的方式，使得第二门钩114进入腔体时更顺畅。在图示的实施方式中，支架102上还安装有阻尼器盖142，阻尼器盖142内设置有容置空间。阻尼器盖142可通过螺钉、过盈配合、焊接、卡扣等方式安装在支架102上，在图示的实施方式中，阻尼器盖142通过卡扣安装在支架102上。
请结合图87，直线式阻尼器包括粗杆部144和细杆部146，细杆部146可伸缩地连接粗杆部144，粗杆部144收容在容置空间，并转动连接在容置空间的内部，直线式阻尼器可以绕粗杆部144与容置空间内部的连接处转动。细杆部146伸出阻尼器盖142并与摆动件108转动连接。在图87所示的实施方式中，摆动件108的右侧开设有连接孔147，该连接孔147大致呈圆柱形，连接孔147右侧面设有开口。细杆部146的端部连接有圆柱部149，圆柱部149与连接孔147配合连接，实现转动连接。圆柱部149可以与细杆部146一体结构或分体结构，圆柱部149与细杆部一体结构时，可以采用相同材料，也可以采用不同材料。在此不作具体限定。
可以理解，在其它实施方式中，连接孔147的形状还可以是其它形状，例如呈圆球形，细杆部146端部的形状与连接孔147的形状相匹配即可，如呈球形。在此不作具体限定。
可以理解，在其它实施方式中，也可以省略弹性件，使门钩在关门过程中进行减速过程。
在某些实施方式中，在门钩与驱动件110分离的情况下，弹性件对驱动件110的作用力方向位于弹性件与驱动件110的连接处147和驱动件110转轴的连线上方，在驱动件110受到门钩作用力的情况下，弹性件对驱动件110的作用力方向位于弹性件与驱动件110的连接处147和驱动件110转轴的连线下方。如此，可以使得驱动件110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。
具体地，请结合图88，弹性件对驱动件110的作用力F方向位于弹性件与驱动件110的连接处147和驱动件110转轴 的连线L上方，驱动件110在弹性件的作用力下，具有沿第一方向的转动趋势。请结合图89，弹性件对驱动件110的作用力F方向位于弹性件与驱动件110的连接处147和驱动件110转轴的连线L下方，驱动件110在弹性件的作用力下，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。
在门钩还没有抵接驱动件110时，驱动件110静止，弹性件的作用力作用于驱动件110，使得驱动件110具有顺时针转动的趋势。在门钩抵接驱动件110(如抵接第一臂130)，驱动件110在门钩的作用下，发生逆时针转动，使得弹性件与驱动件110的连接处147也发生逆时针转动，弹性件对驱动件110的作用力方向切换至上述连线下方，驱动件110从具有顺时针转动趋势转换为逆时针转动趋势，此时，驱动件110没有受到限位，在弹性件的作用下，继续沿逆时针转动进而带动门钩加速。
驱动件110具有转动趋势转换的过程，会使得驱动件110转动的角度较大，驱动件110转动角度较大可以带动第二门钩114更能深入腔体中，进而使得门体200关上时更紧密。
需要说明的，初始状态下，弹性件与驱动件110的连接处147的位置，与驱动件110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，弹性件与驱动件110的连接处147的位置，接近驱动件110转动趋势转换的临界位置，使得在门钩抵接到驱动件110时，初始速度较大的门钩就可使驱动件110沿逆时针转动而将转动趋势转换，无需花费太多门钩的动能来进行转动趋势的转换。
在某些实施方式中，请参图81，支架102设有限位件148，在门钩与驱动件110分离的情况下，限位件148抵接驱动件110以对弹性件与驱动件110的连接处147进行限位。如此，可以通过限位件148对弹性件与驱动件110的连接处147进行限位。
具体地，限位件148设置在支架102的通孔140左侧上方，用于限制驱动件110沿第一方向所能转动到的限位位置，即限定弹性件与驱动件110的连接处147位于驱动件110转轴上方的位置。在图示的实施方式中，限位件148呈半圆柱形。
在某些实施方式中，请参图82和图86，弹性件包括第一弹性件150和第二弹性件152，驱动件110包括连接部154，第一弹性件150与第二弹性件152均连接连接部154，第一弹性件150与第二弹性件152形成的夹角为锐角。如此，通过两个弹性件的合力来对驱动件110进行驱动。
具体地，在驱动件110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件110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，能够使驱动件110对门钩产生较大的抵持力，使得门体200关闭更紧密。在一个示例中，两个弹性件可均为拉簧。第一弹性件150位于第二弹性件152的上方。可以理解，其它实施方式也可采用其它的弹性件，在此不作具体限定。
第一弹性件150的一端勾住支架上的定位柱，另一端勾住连接部154。第二弹性件152的一端勾住支架上的另一定位柱，另一端勾住连接部154。
锐角可以是30度、35度、40度等角度，在此不作具体限定。
在某些实施方式中，阻尼组件104包括盖体156，盖体156安装在支架102并盖设驱动件110。如此，可以避免驱动件110在转动过程与其它结构件发生干涉。
具体地，盖体156可整体盖设驱动件110或盖设驱动件110的大部分，利用盖体156将驱动件110与其它结构件间隔开，避免驱动件110在转动过程中与其它结构件发生干涉而导致无法关门或关门不顺畅的现象。盖体156可通过螺钉、过盈配合、焊接、卡扣等方式安装在支架102上。在图示的实施方式中，盖体156通过螺钉安装在支架102上。
以下说明下本申请实施方式的开关门组件100的原理过程。
初始和终止状态的说明：初始状态(即第二门钩114还没抵接驱动件110)，第一弹性件150和第二弹性件152连接支架102和驱动件110，两弹性件的合力方向位于弹性件与驱动件110的连接处147和驱动件110转轴的连线上方，此时弹性件的作用力(合力)迫使驱动件110具有顺时针转动的趋势。同时，驱动件110被支架102上的限位件148限制住顺时针运动。摆动件108分别与阻尼器106和驱动件110转动连接，且摆动件108可绕驱动件110自由转动。终止状态，第二门钩114拉动驱动件110向外移动，此时摆动件108与驱动件110的角度最大，并带动第一弹性件150和第二弹性件152和阻尼器106运动。在运动过程中，当弹性件的作用力(合力)方向位于弹性件与驱动件110的连接处147和驱动件110转轴的连线上方时，弹性件提供给驱动件110的力由逆时针转动的力变为使驱动件110顺时针转动的力。当第二门钩114被拉出后，驱动件110沿顺时针转动到初始位置，同时第一和第二弹性件152和阻尼器106恢复到初始状态。
(一)实现缓关门/软关门的开关门组件100的平稳关门过程：
1)如图81、图82、图90及图91所示，第二门钩114在一定的初速度条件下，最先接触驱动件110的第一臂130， 并迫使其绕着转轴逆时针转动到与摆动件108重合，该过程中，阻尼器106并未起到阻碍作用(即，第二门钩114在与第一臂130碰撞后，无明显回弹现象，以免第二门钩114在第一臂130与第二臂132之间的间隔134内来回碰撞，造成停滞现象)。同时，弹性件的作用力方向转动到弹性件与驱动件110的连接处147和驱动件110转轴的连线下方，驱动件110的第二臂132快速与第二门钩114接触。
2)如图92至图95所示，因为弹性件作用力方向的改变，弹性件作用力变为使驱动件110逆时针转动的力，驱动件110带动摆动件108一起转动，并驱动第二门钩114运动；直到停止运动，关门结束。
(二)实现缓关门/软关门的开关门组件100的开门过程：
如图94至图97、图81及图82所示，人力驱动下，第二门钩114带动驱动件110顺时针转动。在此过程中，弹性件作用力由迫使驱动件110逆时针转动的力变为顺时针转动的力。当第二门钩114被拉出后，驱动件110转动到初始位置。最后，第一弹性件150和第二弹性件152、摆动件108和阻尼器106恢复到初始状态，开门结束。
综上，本申请实施方式提供一种分体式旋转驱动方式的开关门组件100，可以解决侧拉门家用电器开关门过程中连续平稳关门的问题。在关门过程中，该开关门组件100可以连续平稳的让驱动件110转动并带动门钩进行关门动作；在开门过程中，该开关门组件100可以顺利让驱动件110主动进行开门操作，并停在指定的位置上，从而可以顺利的实现多次开关门的问题。综上，该开关门组件100通用性强，易于应用和推广。
本申请实施方式还提供一种家用电器，其包括：
腔体；
门体200，转动地连接在腔体的一侧；
上述任一实施方式的开关门组件100，支架102安装在腔体，门钩安装在门体200。
上述家用电器中，在门钩向驱动件110施加作用力的情况下，驱动件110可先转动一预设角度后带动摆动件108压缩阻尼器106，进而可实现在门钩作用于驱动件110初期时，门钩不至于被阻尼器106回弹而造成关门不顺畅甚至停滞现象，提升了用户体验。
具体地，家用电器包括但不限于微波炉、烤箱(包括电烤箱、微波烤箱和微蒸烤一体机)、蒸箱、洗碗机、消毒柜等具有门体200的家用电器。
