所述平移锁上具有与所述锁孔相配合的锁销，当所述平移锁处于所述锁定位置时所述锁销伸入至所述锁孔内，以使所述副门锁定于所述主门。
进一步地，所述弹性件为压缩弹簧，设置于所述平移锁背离所述锁销的一侧，其第一端与所述平移锁连接，其第二端直接或间接地连接于所述主门，配置成所述平移锁处于所述解锁位置时所述弹性件被压缩并产生弹性预紧力，在所述主门处于打开的过程中利用该弹性预紧力促使所述平移锁朝向所述锁定位置移动。
进一步地，安装盒，沿前后方向安装于所述主门上，所述安装盒具有朝向所述平移锁的套管，所述压缩弹簧的第二端套设于所述套管上。
进一步地，所述平移锁还具有向所述主门外部延伸的按压部，所述按压部配置成在所述平移锁处于所述锁定位置，通过操作所述按压部以带动所述平移锁朝远离所述锁扣的方向平移，以解除所述副门与所述主门间的锁定。
进一步地，所述主门与所述箱体相对的区域、以及所述主门与所述副门相对的区域上均设置有门封条，以密封所述主门与所述副门、所述主门与所述箱体之间的缝隙。
本发明的冰箱中，由于平移锁可在一锁定位置和一解锁位置之间往复平移地安装于主门，弹性件安装于主门，向平移锁施加促使其朝锁定位置移动 的弹性预紧力，锁扣设置于副门上，解锁部设置于箱体上。因此，当主门被打开时，平移锁可在弹性预紧力的作用下朝向锁扣移动，平移锁与锁扣锁定在一起；当主门被关闭时，平移锁在主门的带动下朝向箱体移动，平移锁靠近箱体的一端抵触于解锁部，解锁部的促使作用下使得平移锁向远离锁扣的方向移动，最终当主门被完全关闭后，平移锁与锁扣解除锁定，并处于解锁位置，主门与副门也被解除锁定。因此，本发明的冰箱通过采用纯机械的装置来实现避免在开启主门时，副门异常被打开的情况，结构简单，安全可靠。
进一步地，本发明的冰箱中，引导斜面可以设置成光滑的弧形面，平移锁的后端形成弧形的抵触斜面，当引导斜面与抵触斜面抵触上后，可以减小其之间的摩擦，使引导斜面光滑过渡到平移锁的上方，最终使平移锁稳定地处于解锁位置。
根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。

请参见图1，在本发明提出一种冰箱10，其可以包括箱体100、主门200和副门300。
箱体100的内部限定有第一储物空间110，第一储物空间110具有向前的第一开口，主门200可转动地安装于箱体100的外侧，以开闭第一开口。主门200的内部可以限定出第二储物空间210，第二储物空间210具有向前的第二开口，副门300可转动地安装于主门200的外侧，以开闭第二开口。
在本实施例中，箱体100内部的第一储物空间110和主门200内部的第二储物空间210均可以供用户储存食物，并且用户可以根据物品的使用频率或体积大小选择将物品储存在第一储物空间110或第二储物空间210内。例如，用户可以将一些使用频率高且占用空间小的物品储物于第二储物空间210内，将一些使用频率低且占用空间大的物品储物于第一储物空间110内，这样可以避免用户频繁打开门体，降低热量损失，而且第一储物空间110或第二储物空间210能够将冰箱10的储物区域进行划分，有利于用户整理物品。在一些优先的实施例中，第一储物空间110还可以为冰箱10的冷藏室。
请参见图1至图5，本实施例的冰箱10还可以包括平移锁400、弹性件500、锁扣600和解锁部700。
平移锁400可在一锁定位置和一解锁位置之间往复平移地安装于主门200，弹性件500安装于主门200，配置成向平移锁400施加促使其朝锁定位置移动的弹性预紧力，锁扣600设置于副门300上，解锁部700设置于箱体100上。
冰箱10配置成：在主门200处于打开状态且副门300处于关闭状态时，使平移锁400处于锁定位置并与锁扣600锁定，从而使副门300锁定于主门200；且在副门300随主门200后移关闭末期，使解锁部700促使平移锁400克服弹性预紧力移动至解锁位置，从而解除副门300与主门200间的锁定。
如背景技术部分所述，为了防止叠门冰箱在开启主门时，副门异常被打开，现有技术中出现了在主门和副门之间设置电磁锁。但是这种方式也具有一定的缺陷，例如，电磁锁的设置必然导致冰箱的成本提升和生产工艺的复杂化，而且在使用的过程中，消耗电能，难以推广。
为了克服上述现有技术的缺陷，本实施例的冰箱10采用纯机械的装置 来实现避免在开启主门时，副门异常被打开的情况，结构简单，安全可靠。
具体地，主门200的门体内部可以限定出一用于容纳平移锁400的安装空间220，平移锁400设置于安装空间220内，锁扣600可以设置于副门300朝向主门200的一侧，弹性件500设置于安装空间220内并为平移锁400提供弹性预紧力，该弹性预紧力可以使得平移锁400具有向锁扣600移动的趋势。
当主门200被打开时，平移锁400在弹性预紧力的作用下朝向锁扣600移动，以使得平移锁400与锁扣600锁定在一起，使平移锁400处于锁定状态。由于锁扣600设置于副门300上，这时主门200与副门300也就被锁定在一起。主门200继续被打开过程，副门300处于关闭状态，防止第一储物空间110的物品受惯性而带出，而且还可以避免冰箱10的热量损失。
当主门200被关闭时，平移锁400在主门200的带动下朝向箱体100移动，并且使得平移锁400靠近箱体100的一端抵触于解锁部700，并在解锁部700的促使作用下使得平移锁400向远离锁扣600的方向移动，最终当主门200被完全关闭后，平移锁400与锁扣600解除锁定，并处于解锁位置，主门200与副门300也被解除锁定。
特殊地，平移锁400可上下平移地安装于主门200，弹性件500对平移锁400施加的弹性预紧力朝上，解锁部700的前侧具有从上至下逐渐向后倾斜延伸的引导斜面，在平移锁400后移过程中，其后端在引导斜面的引导下逐渐向下平移以抵达解锁位置。
当主门200被关闭时，平移锁400在主门200的带动下朝向箱体100移动，平移锁400的后端抵触于引导斜面上。由于引导斜面从上至下逐渐向后倾斜延伸，当平移锁400继续向后移动时，在引导斜面的引导下，平移锁400向下运动。也即是，平移锁400受到引导斜面向下的分力，促使平移锁400朝向远离锁扣600的方向移动，最终使平移锁400与锁扣600脱开，并解除锁定。
进一步地，在主门200完全关闭后，平移锁400的后端完全通过引导斜面，整个平移锁400处于解锁部700的下方，平移锁400抵靠于解锁部700下方。这时由于弹性件500在平移锁400的移动过程中被压缩，弹性件500此时依然为平移锁400提供向上的弹性预紧力，在该弹性预紧力与解锁部700的共同作用下，平移锁400处于平衡状态，以稳固处于解锁位置。
请参见图3和图5，在一些实施例中，箱体100的前侧开设有开口朝向平移锁400的容置腔室120，解锁部700为从容置腔室120上壁向下延伸出的长条状，引导斜面形成于解锁部700相对于平移锁400的一面上。
也即，在本实施例中，平移锁400可沿主门200的前后方向设置于安装空间220，并且平移锁400的一端朝向箱体100延伸。当主门200处于完全关闭的状态时，平移锁400能够伸入至容置腔室120，并在解锁部700与弹性件500的共同作用下处于解锁位置，用户此时可以根据需要打开主门200或者副门300。
当主门200在被逐渐打开的过程中，平移锁400向远离解锁部700的方向移动。当平移锁400的后端移动至与解锁部700的引导斜面抵触的位置段时，在弹性件500的作用下促使平移锁400向上运动，以逐渐靠近锁扣600，最终使平移锁400锁定在锁扣600上，使平移锁400处于锁定位置。也就是说，用户在开启主门200的过程中，只需将主门200移动一小部分距离(即将平移锁400伸入容置腔室120的部分拉出)就可以实现主门200与副门300锁定。
当然，本领域技术人员还可以根据本公开的技术方案作简单地变形也能够实现上述技术效果。例如，解锁部700还可以设置成从容置腔室120下壁向上延伸，对应地，弹性件500对平移锁400施加的弹性预紧力朝下，也即是，平移锁400可以设置于解锁部700的上方，平移锁400向下移动后处于锁定位置，向上移动后处于解锁位置。
请参见图3和图5，在一些实施例中，引导斜面可以设置成光滑的弧形面，并且平移锁400的后端形成弧形的抵触斜面，当引导斜面与抵触斜面抵触上后，可以减小其之间的摩擦，使引导斜面光滑过渡到平移锁400的上方。
在一些实施例中，锁扣600沿水平方向延伸，其上具有锁孔610，并且平移锁400上具有与锁孔610相配合的锁销410，当平移锁400处于锁定位置时锁销410伸入至锁孔610内，以使副门300锁定于主门200。
具体地，设置于主门200上的安装空间220朝向副门300且与锁扣600相对的位置处可以设置一开口(图中未示出)，锁扣600沿水平方向主门200延伸。当平移锁400处于锁定位置时，锁扣600穿设于该开口处，使得锁孔610处于安装空间220内，这时与锁销410相配合，以实现副门300锁定于主门200。
当平移锁400处于解锁位置时，平移锁400向远离锁扣600的方向移动，使得锁销410脱离锁孔610，副门300与主门200解除锁定，用户此时可以任意开启副门300与主门200。
在一些实施例中，弹性件500为压缩弹簧，压缩弹簧的数量可以为多个，多个压缩弹簧可以均匀地设置于平移锁400背离锁销410的一侧，以使平移锁400在移动时保持稳定。多个压缩弹簧还可以设置于安装空间220内，弹性件500的第一端与平移锁400连接，第二端直接地连接于主门200，也即，第二端直接地连接于安装空间220的内壁上，配置成平移锁400处于解锁位置时弹性件500被压缩并产生弹性预紧力，在主门200处于打开的过程中利用该弹性预紧力促使平移锁400朝向锁定位置移动。
请参见图3、图5和图6，在另外一些实施例中，弹性件500还可以通过安装盒230间接地安装于主门200与平移锁400之间。安装盒230沿主门200的前后方向设置在安装空间220内，其朝向平移锁400的一侧面上具有套管232，套管232的数量与压缩弹簧的数量相等，压缩弹簧第二端套设于套管232上。
在一些实施例中，平移锁400还具有向主门200外部延伸的按压部420，按压部420配置成在平移锁400处于锁定位置时，通过操作按压部420以带动平移锁400朝远离锁扣600的方向平移，以解除副门300与主门200间的锁定。
在本实施例中，当用户打开主门200后，副门300与主门200在平移锁400的作用下会处于锁定状态，此时，如果用户需要在打开副门300就可以利用通过操作按压部420，以将平移锁400与锁扣600脱离，实现在主门200打开且副门300与主门200处于锁定状态时，打开副门300。
在一些实施例中，主门200与箱体100相对的区域、以及主门200与副门300相对的区域上均设置有门封条240，以密封主门200与副门300、主门200与箱体100之间的缝隙，以防止在副门300和主门200均处于关闭状态下外部空气进入第一储物空间110和第二储物空间210内。
本发明的工作原理：当冰箱10的副门300和主门200均处于关闭状态时，平移锁400的后端伸入箱体100上的容置腔室120，在解锁部700的作用下使其处于远离锁扣600的位置，也即平移锁400处于锁定位置，副门300和主门200之间没有被锁定，用户可以在副门300和主门200均处于关闭状 态时任意打开其中一个。
当用户打开主门200时，平移锁400逐渐地被拉出，并且平移锁400的后端与解锁部700相接触，并在解锁部700的引导斜面的引导和弹性件500的弹性预紧力的驱动下朝向锁扣600移动，最终平移锁400的锁销410伸入锁扣600的锁孔610内，使得副门300和主门200被锁定，这样能够防止用户在单独地开启主门200时副门300被打开，避免了第二储物空间210内的物品被带出的风险，提高了用户的体验感。
当用户打开主门200后又欲打开副门300时，此时副门300和主门200处于锁定状态，用户可以通过手动操作按压部420，以带动平移锁400向远离锁扣600的方向移动，最终使副门300和主门200解锁，以实现在主门200后打开副门300。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
