一种碎冰装置及冰箱
本申请要求于2015年12月31日提交中国专利局、申请号为201511034383.5、发明名称为“一种碎冰装置及冰箱”，以及于2015年12月31日提交中国专利局、申请号为201511034935.2、发明名称为“一种碎冰装置及冰箱”的两件中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及冰块的制备设备的技术领域，尤其涉及一种碎冰装置及冰箱。
背景技术
随着科学技术的不断发展，人们生活水平的不断提高，为适应人们对生活质量越来越高的要求，家用电器的功能也在不断增加，如在冰箱上添加制冰机等。该制冰机包括制冰装置和碎冰装置，制冰装置将冰块制备出来后储存在桶状容器中，以便用户取用。同时，为了方便使用，技术人员们将该冰箱的出冰方式设置为碎冰模式和冰块模式。在碎冰模式下，用户取用到的是被剪碎的冰块；而冰块模式下，用户取用到的是完整的冰块。然而冰块储存在桶状容器中后，长时间相接触的冰块极易冻结在一起，甚至于整个桶状容器内的冰块都会冻结在一起。为解决该问题，技术人员们采用了在桶状容器内设置搅拌结构来使冰块在桶状容器内运动，从而解决长时间相接触的冰块冻结的问题。
示例的，参考图1所示，现有技术中采用一种制冰机碎冰装置，包括一驱动齿轮01，一从动齿轮02，一本体为轮状的搅冰器03，设置在搅冰器03上的搅冰杆031，驱动齿轮01和从动齿轮02相啮合，驱动齿轮01上同轴穿套有用于切割冰块的若干碎冰刀片04，相邻的两个碎冰刀片04间隔有一定距离。从动齿轮02为中空的环状结构，以使搅冰器03与从动齿轮02同轴套设，且搅冰器03的外周面和从动齿轮02的内环面形成一圈间隙；在需要时使搅冰器03 转动，同时带动搅冰杆031发生转动，搅冰器03上对称设置有两扇形偏心楔块032。
由于该制冰机碎冰装置中碎冰刀片04是同轴穿套在驱动齿轮01上的，因此碎冰刀片04的转动方向与驱动齿轮01相同；搅冰器03与从动齿轮02同轴套设，并在需要转动时由从动齿轮02带动转动，此时搅冰器03和设置在搅冰器03上的搅冰杆031的转动方向与从动齿轮02的转动方向相同并与驱动齿轮01的转动方向相反，搅冰器03上对称设置有两扇形偏心楔块032。且在该方案中，仅有当驱动齿轮01逆时针转动时，两偏心楔块032的大段部分与从动齿轮02的内环面相接触产生摩擦力，从动齿轮02才能够带动搅冰器03发生转动，此时，碎冰刀片04、搅冰器03以及搅冰杆031同时对冰块产生图示中向右方向的力，使容器内的冰块运动。当驱动齿轮01顺时针转动时，两偏心楔块032的小段部分和从动齿轮02的内环面形成间隙，搅冰器03和从动齿轮02脱离开来，使得从动齿轮02无法带动搅冰器03转动，搅冰器03停止工作。然而在搅冰器03运转时，使冰块运动的力均为同一方向(图1所标示的右方向)的力，因此冰块的运动为整体向容器右方向移动，冰块之间的相对运动不大，搅拌效果不明显。
发明内容
本发明的实施例提供一种碎冰装置，能够充分搅拌堆积在桶状容器内的冰块，增大冰块之间的相对运动，从而使搅拌效果增强。
为达到上述目的，本发明的实施例采用如下技术方案：
一种碎冰装置，包括储冰桶，所述储冰桶内设有可转动的搅拌器，所述搅拌器的下方设有可转动的冰刀组件，所述搅拌器的转轴的轴线与所述冰刀组件的转轴的轴线互为异面直线。
本发明同时提供一种冰箱，包括冰箱门，所述冰箱门的内壁设有制冰机，所述制冰机内设有上述技术方案所述的碎冰装置。
相较于现有技术，本发明提供的碎冰装置，由于搅拌器的转轴的轴线与冰刀组件的转轴的轴线互为异面直线，因此搅拌器转动时 对冰块产生的作用力的方向所在的直线与冰刀组件的转动时对冰块产生的作用力的方向所在的直线也互为异面直线，也即搅拌器搅动时会与冰刀组件发生扰动，使冰块在储冰桶内做不规则运动，从而增大了冰块之间的相对运动，使得搅拌器的搅拌效果达到最大。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要理解的是，术语“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”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发明和简化描述，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发明的限制。
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该特征。
带有制冰和碎冰功能的冰箱是采用在冰箱上增加冰块制备部分和碎冰装置来实现此功能。
参照图13，该冰箱的冰箱门100上设置有制冰机，制冰机包括制冰装置和碎冰装置200，制冰装置将制备好的冰块输送至该碎冰装置的储冰桶内，在用户需要取用整冰时将储冰桶内的冰块送出，或在用户需要取用碎冰时将储冰桶内的冰块剪碎后送出。
制冰装置将冰块制备完成后输送到储冰桶5内，储冰桶5内设置有可转动的搅拌器1和可转动的冰刀组件2，搅拌器1和冰刀组件2通过自身转动带动储冰桶5内的冰块产生运动，并按照用户的实际需求送出整冰或剪碎冰块后送出碎冰。
图2、图3、图4以及图6所示为本发明实施例碎冰装置中的一个具体实施例，本实施例中所述的碎冰装置，包括储冰桶5，储冰 桶内设有可转动的搅拌器1，搅拌器1的下方设有可转动的冰刀组件2，搅拌器1的转轴11的轴线与冰刀组件2的转轴21的轴线互为异面直线。
这样一来，相较于现有技术，本发明实施例提供的碎冰装置，由于搅拌器1的转轴11的轴线与冰刀组件2的转轴21的轴线互为异面直线，因此搅拌器1转动时对冰块产生的作用力的方向所在的直线与冰刀组件2转动时对冰块产生的作用力的方向所在的直线也互为异面直线，也即搅拌器1搅动时会与冰刀组件2发生扰动，使冰块在储冰桶5内做不规则运动，冰块之间的相对运动加大，搅拌器1的搅拌效果达到最大，从而避免相邻冰块之间相对运动不明显而长时间接触以致发生冻结。
进一步地，为使该搅拌器1的搅拌效果更好，参考图2、图3以及图4所示，搅拌器1的转轴11的轴线与冰刀组件2的转轴21的轴线互相垂直。当搅拌器1的转轴11的轴线与冰刀组件2的转轴21的轴线互相垂直时，搅拌器1所产生的作用力，和冰刀组件2转动时产生的作用力的方向也相互垂直，不会产生同一方向上的分力，扰动作用达到最大，使得该搅拌器的搅拌效果也同时达到最佳。
进一步地，参考图2、图3以及图4所示，搅拌器1的转轴11与冰刀组件2的转轴21均为水平设置。将搅拌器1的转轴11和冰刀组件2的转轴21均为水平设置后，在该碎冰装置运转的过程中，搅拌器1的转轴11在转动过程中轴向上所受到的力被均匀分布，避免某一部位过度受力出现压弯或断裂的情况；且储冰桶内的冰块在堆积过程中，冰刀组件2的碎冰刀片的刀面两侧受力均等，且刀刃和刀背部分由于面积过小，不易受到挤压，在转动过程中，冰刀组件2的碎冰刀片的刀面两侧仅需克服与冰块之间的摩擦力，这使得冰刀组件2的碎冰刀片在转动过程中不会发生弯折。但若将搅拌器1的转轴11倾斜设置，搅拌器1的转轴11靠近制冰部件的一侧在受到冰块的挤压后，挤压所产生的力不能被均匀地分布在整个轴上，轴的安装部位更容易发生弯折；若将冰刀组件2的转轴21倾斜设置， 在该碎冰装置运转的过程中，冰刀组件2的碎冰刀片的刀面会额外受到冰块的挤压，以致冰刀组件2的碎冰刀片在转动过程中还需要克服来自冰块的压力，增大了冰刀组件2的碎冰刀片被压弯甚至出现断裂的可能。同时，搅拌器1的转轴11和/或冰刀组件2的转轴21倾斜设置还会增加轴的安装难度。因此，将搅拌器1的转轴11与冰刀组件2的转轴21均为水平设置可以最大程度地保护搅拌器1和冰刀组件2，同时降低安装难度。搅拌器的转轴11横跨所述储冰桶5，可以保证搅拌器1具有尽可能大的搅拌空间，能够覆盖整个冰刀组件2的上方区域。
为使搅拌器1的搅拌效果更好，参考图2、图3以及图4所示，搅拌器1的转轴11上设有多个搅拌爪12，多个搅拌爪12沿搅拌器1的转轴11的周向均匀分布。在搅拌器1工作时，设置在搅拌器1的转轴11上的多个搅拌爪12能够同时从各个不同的放向伸入冰块内部搅动，增大搅拌器1的搅拌范围。而多个搅拌爪12在搅拌器1的转轴11的周向上均匀分布，能够保证在搅拌器1搅拌时，搅拌器1的转轴11各个时刻对周向上的冰块产生的作用力的大小相同，保证了搅拌过程的稳定性，避免出现搅拌不均匀的情况。同时，在不与冰刀组件2的碎冰刀发生干涉的前提下，搅拌爪12在竖直方向上的长度应尽可能长，以使搅拌爪12的搅拌范围尽可能地覆盖碎冰刀上部的储冰桶空间，搅拌器1的搅拌范围更大，搅拌效果更好。
为确保搅拌器1的搅拌轴11在使用时的稳定性，参考图2、图3以及图4所示，多个搅拌爪12沿搅拌器1的转轴11的轴向错开设置，且相邻两个搅拌爪12沿搅拌器1的转轴11的轴向的间距相等。将搅拌爪12在搅拌器1的转轴11的轴向上均匀排布，使得搅拌器1在搅拌过程中能够在使用尽量少的搅拌爪12的情况下，将搅拌器1所覆盖的部分充分且均匀地进行搅拌，在节约成本的情况下最大程度地提高搅拌效率。相邻两个搅拌爪12沿搅拌器1的转轴11的轴向的间距相等使得搅拌器1的转轴11在转动时所受到的力被均匀地分布在搅拌器1的转轴11上，防止搅拌器1的搅拌轴11出现受力 不均导致变形甚至断裂的情况。
例如，参考图3和图4所示，沿搅拌器1的转轴11的周向均匀设置四个搅拌爪，相邻两个搅拌爪12所成的角α的度数为90°。α＝360°/n，其中n为搅拌爪12的数目。在搅拌器1的转轴11上设置四个搅拌爪12，使得搅拌器1在搅拌过程中，四个搅拌爪12能够分别伸入搅拌器1的转轴11周向上的四个方向中堆积的冰块中间，保证了在只设置四个搅拌爪12的情况下将储冰桶内的冰块充分搅动，并能将体积较大的冻结冰块分离成较小块状，再由冰刀组件2进行分离或破碎，减轻了冰刀组件2的工作压力，延长了冰刀组件2的使用寿命。而这四个搅拌爪12在搅拌器1的转轴11的周向上均匀分布，保证了在搅拌器1搅拌时，搅拌器1的转轴11在搅拌器1工作的情况下所受到的作用力被均匀地分布在该转轴上，防止搅拌器1的搅拌轴11出现受力不均导致变形甚至断裂的情况，保证了搅拌过程的稳定性。
进一步地，参考图3和图4所示，多个搅拌爪12均沿垂直于搅拌器1的转轴11的方向延伸。搅拌爪12垂直于搅拌器1的转轴11设置时，能够保证在搅拌器1的转轴11转动时，搅拌爪12的各个部位均能受力且不会有冰块卡在搅拌爪12与搅拌器1的转轴11之间，保证了搅拌器1的正常运转。
参考图2所示，冰刀组件2的转轴21连接有用于驱动冰刀组件2的转轴21转动的驱动装置(图中未示出)，冰刀组件2的转轴21通过传动组件3与搅拌器1的转轴11传动连接，以驱动搅拌器1的转轴11转动。使用传动组件3来驱动搅拌器1的转轴11转动，相较于直接使用电机等驱动装置来驱动的方式，使用传动组件3来驱动的方式耗能相对较小，且噪音更低。传动组件3可以为涡轮传动组件、链传动组件、带传动组件或者齿轮传动组件。
其中，采用涡轮传动组件能够获得更高的传动精度，且结构尺寸紧凑。但涡轮传动组件的轴向力大、易发热且传动效率低，同时涡轮传动组件对工作环境的要求较高，设备易损坏。
采用链传动组件具有安装精度低和传动结构简单的优势，但链传动组件的传动平稳性差，传动链的抗冲击、振动能力差，极易损坏。
采用带传动组件具有结构简单、成本低廉的优势，且带传动组件自身具有缓和振动、吸收冲击的功能，能够防止其他构件发生损坏，但带传动组件中，带的寿命较短，需经常更换，且带传动组件的带极易打滑，使得传动比经常发生变化，不能保证机构的稳定运转。
参考图2、图3、图4以及图5所示，传动组件3采用齿轮传动组件时，传动组件3包括第一中间轴31和第二中间轴32，第一中间轴31与冰刀组件2的转轴21通过第一圆柱齿轮组33传动连接，第一中间轴31与第二中间轴32通过第二圆柱齿轮组34传动连接，第二中间轴32与搅拌器1的转轴11通过锥齿轮组35传动连接。
第一圆柱齿轮组包括第一圆柱齿轮331和第二圆柱齿轮332，第一圆柱齿轮331固定套设在冰刀组件2的转轴21上，第二圆柱齿轮332固定套设在第一中间轴31上，且第一圆柱齿轮331和第二圆柱齿轮332相啮合，以保证在冰刀组件2的转轴21被驱动装置(图中未示出)驱动时，第一中间轴31能够同步转动，此时，冰刀组件2的转轴21与第一中间轴31相互平行；
第二圆柱齿轮组34包括第二圆柱齿轮332和第三圆柱齿轮341，第三圆柱齿轮341固定套设在第二中间轴32上，且第二圆柱齿轮332和第三圆柱齿轮341相啮合，以保证在第一中间轴31转动时，第二中间轴32能够同步转动，此时第一中间轴31和第二中间轴32相互平行，也即冰刀组件2的转轴21、第一中间轴31以及第二中间轴32这三根轴两两平行；
锥齿轮组35包括第一锥齿轮351和第二锥齿轮352，第一锥齿轮351固定套设在第二中间轴32上，第二锥齿轮固定套设在搅拌器1的转轴11上，且第一锥齿轮351和第二锥齿轮352相啮合，第二中间轴32在转动时，带动固定套设在其上的第一锥齿轮351转动， 从而驱动与第一锥齿轮351相啮合的第二锥齿轮352转动，进而带动穿设在第二锥齿轮352中的搅拌器1的转轴11转动，搅拌器1开始搅拌。由于搅拌器1的转轴11的轴线与冰刀组件2的转轴21的轴线必然互为异面直线，因此，固定穿设在第二锥齿轮352中的搅拌器1的转轴11，与固定穿设在第一锥齿轮351中的第二中间轴32之间也必须具有一定的角度β，若采用圆柱齿轮啮合的方式，无法实现所需的搅拌器1的转轴11和第二中间轴32之间的传动，而锥齿轮相啮合时的轴的交角却能够满足该要求，在使用时，仅需根据角度β的实际角度来计算出所需锥齿轮的各项参数，选定合适的锥齿轮组35来进行传动，进而满足本发明中的实施例的要求，实现本发明中的实施例。且锥齿轮自身使用寿命长，能够承载负荷较大，这也在一定程度上保障了碎冰装置的稳定运转。
采用齿轮传动组件来驱动搅拌器1的转轴11时，齿轮传动组件自身的结构较为简单，传动的稳定性和传动的效率都较高，由于其自身稳定性较高，使得传动工作的可靠性也较高。齿轮自身硬度较大、齿轮传动组件的对安装环境的要求不高，这使得齿轮传动组件的使用寿命也相应较长。搅拌器1的转轴11在使用齿轮传动组件驱动时，搅拌器1的运转更为平稳，噪音较低，且采用了齿轮传动组件的传动组件3的使用寿命长，无需频繁更换传动组件3中的构件，增强了搅拌器1的连续运转能力。
用户在使用冰块模式取用整冰时，有时会出现不出冰的情况，经技术人员研究后发现，是由于有冻结在一起的冰块将整冰的出口处堵塞导致，因此，为解决冻结在一起的冰块堵塞整冰的出口处的问题，本发明的碎冰装置还包括如下结构：
参考图6和图7所示，冰刀组件2包括转轴21、定冰刀22、动冰刀23以及冰块分离结构24，转轴21可带动动冰刀23转动，定冰刀22和冰块分离结构24分别位于转轴21的两侧，且定冰刀22和冰块分离结构24均相对于储冰桶5固定，当转轴21带动动冰刀23沿第一方向转动时，储冰桶5内的冰块可在动冰刀23与定冰刀 22的剪切力下破碎，当转轴21带动动冰刀23沿与第一方向相反的第二方向转动时，冻结在一起的冰块可在动冰刀23与冰块分离结构24的配合下分离。由于在转轴21的两侧分别设置了定冰刀22和冰块分离结构24，使得该碎冰装置在碎冰模式下转轴21向第一方向转动时，动冰刀23向定冰刀22所在的方向下压，将位于动冰刀23和定冰刀22之间的冰块剪碎；在冰块模式下当转轴21向与第一方向相反的第二方向转动时，动冰刀23向冰块分离结构24所在的方向下压，对位于冰块分离结构24与动冰刀23之间的冻结在一起的冰块的上表面施加下压的力，而冰块分离结构24与该冻结在一起的冰块的下表面的接触部分提供相应的支撑力，使得该冻结在一起的冰块被分离成冰块，用户在使用冰块模式取用整冰时不会出现冻结在一起的冰块将整冰的出口处堵塞的情况。
进一步地，参考图7和图8所示，定冰刀22的一端可转动地连接于转轴21上，另一端固定连接于固定座221上，固定座221相对于储冰桶5固定，冰块分离结构24固定于定冰刀22与转轴21连接的一端。另外地，冰块分离结构24也可以固定设置在储冰桶5内而不与定冰刀22的一端固定。但在冰块分离结构24工作时，安装在储冰桶5内的冰块分离结构24与储冰桶5的连接部位的边缘也会受到一定程度上的剪力，连接部位难以提供单独的支撑力，长时间使用会降低连接部位的可靠性甚至造成冰块分离装置24从连接部位脱落。相反地，将冰块分离结构24连接在定冰刀22与转轴21连接的一端时，冰块分离装置24在受力时，相对于储冰桶5固定设置的固定座221和转轴21均能提供足够的支撑力，用以抵消该冰块分离装置24上所承受的力，使冰块分离装置24自身受力较小，延长了该冰块分离装置24的使用寿命。
为降低上述实施例中提到的连接部位在长时间使用中可靠性被降低的情况，参考图7、图8和图9所示，冰块分离结构24为板状结构，且与定冰刀22一体成型。板状结构的冰块分离结构24更加容易安装，且当该冰块分离结构24与定冰刀22一体成型后，由于 冰块分离结构24和定冰刀22之间未采用连接工艺，冰块分离结构24和定冰刀22之间没有了连接部位，不会出现连接部位在长时间工作过程中因为连接可靠性降低而断开的情况，保障了该碎冰装置工作的稳定性。为降低冰块分离结构24与定冰刀22一体成型时的工艺难度，优选将冰块分离结构24和定冰刀22设置为相同厚度。
为了适应不同设备在尺寸或碎冰效率上的需求等，参考图6至图5所示，定冰刀22为多个，相邻两个定冰刀22之间的转轴21上设有动冰刀23，至少一部分定冰刀22连接有冰块分离结构24，相邻两冰块分离结构24之间的间隙仅可允许一个冰块通过。本装置中的定冰刀22、动冰刀23以及冰块分离结构24的数目可根据实际需求进行选择，这就增加了该碎冰装置的灵活性。定冰刀22和动冰刀23间隔设置，则保证了在碎冰模式下，定冰刀22和动冰刀23在转轴21沿第一方向转动时，动冰刀23向定冰刀22方向下压时，位于动冰刀23和定冰刀22之间的每一个冰块都能在动冰刀23和定冰刀22的配合下被剪碎。当且仅当定冰刀22和动冰刀23在交错瞬间，定冰刀22的两侧均为动冰刀23时，定冰刀22朝向动冰刀23的一侧对冰块提供向上的支撑力，定冰刀22两侧的动冰刀23均对该冰块提供朝下的压迫力，该冰块才能够在动冰刀23和定冰刀22配合被剪碎。若安装在转轴21上的定冰刀22的一侧或两侧仍为冰刀时，则会造成该定冰刀22与其一侧或两侧的定冰刀在碎冰模式下无法与动冰刀23进行配合，不能对该定冰刀22与其一侧或两侧的定冰刀附近的冰块进行剪碎；同理，若安装在转轴21上的动冰刀23的一侧或两侧仍为动冰刀时，碎冰模式下该动冰刀23与其一侧或两侧的动冰刀无法配合，不能剪碎该动冰刀23与其一侧或两侧的动冰刀附近的冰块。设置多个冰块分离结构24且相邻两冰块分离结构24之间的间隙仅可允许一个冰块通过则确保了在冰块模式下，转轴21沿第二方向转动时，被动冰刀23和冰块分离结构24所分离开来形成的冰块，能够从该间隙中通过并通过整冰的出口处，便于人们取用。
例如，参考图6、图7、图8以及图10所示，定冰刀22为三个，中间的定冰刀连接有冰块分离结构24，冰块分离结构24在沿转轴21的轴向方向上与储冰桶5的内壁之间的间隙m、n均仅可允许一个独立的冰块4通过。这里所说的独立的冰块是指由制冰盒中的任意一个制冰格制备出来的，且不与其他冰块冻结在一起的冰块。本实施例中，三个定冰刀22和四个动冰刀23间隔设置，在转轴21沿第一方向转动时，该碎冰装置能够将位于动冰刀22和定冰刀23之间的冰块剪碎；当转轴21沿与第一方向相反的第二方向转动时，动冰刀23能够配合冰块分离结构24将冻结在一起的冰块分离开来，且仅当被冻结在一起的冰块被分离成可通过间隙m、n的情况下，被分离形成的冰块才会被输送至整冰的出口处并能够从整冰的出口处中滑出。
进一步地，参考图6、图7、图11以及图12所示，动冰刀23包括刀刃231和刀背232，当转轴21带动动冰刀23沿第一方向转动时，动冰刀23的刀刃231与定冰刀22的刀刃222相互配合将储冰桶5内的冰块剪碎，当转轴21带动动冰刀23沿第二方向转动时，动冰刀23的刀背232与冰块分离结构24相互配合将冻结在一起的冰块分离。在转轴21沿第一方向转动的碎冰模式下，动冰刀23需要与定冰刀22配合将冰块剪碎，因此，在碎冰模式下，动冰刀23和定冰刀22所需要提供的力更大，这就增加了驱动转轴21的驱动装置的负荷，而若在动冰刀23上设置刀刃231和刀背232，在动冰刀23的刀刃231向定冰刀22部分下压时，在转轴21的转速不变的情况下，较薄的刀刃231比较厚的刀背232能够提供更大的压强，以配合定冰刀22将冰块剪碎。同时，在碎冰模式下，定冰刀22上用以与动冰刀23的刀刃231配合的部分也可以减薄，设置为定冰刀22的刀刃232，以减轻定冰刀22的工作强度。而在转轴21沿第二方向转动的冰块模式下，动冰刀23的刀背232向冰块分离结构24所在的方向下压，对位于冰块分离结构24与动冰刀23之间的冻结在一起的冰块4’的上表面施加下压的力F1和F2，而冰块分离结构 24与该冻结在一起的冰块4’的下表面的接触部分提供相应的支撑力F3，使得该冻结在一起的冰块4’在动冰刀23的刀背232与冰块分离结构24相互配合下被分离成冰块4。此时动冰刀23与冻结在一起的冰块4’接触的部分仅需提供下压力即可，因此无需减薄，动冰刀23上与该冻结在一起的冰块4’接触的部分即为动冰刀23的刀背232。若将动冰刀23的刀背232处减薄，不仅会增加动冰刀23的加工难度和安装难度，同时会导致冰块模式下分离被冻结在一起的冰块时，冰块的完整性会被破坏，不利于取得完整冰块。
进一步地，参考图6至图11所示，动冰刀23的刀刃231和定冰刀22的刀刃222均为锯齿状，动冰刀23的刀背232为锯齿状，所述冰块分离结构24的延伸端的端部倾斜上翘。锯齿状的刀刃比平滑的薄刀刃更为锋利，在转轴21带动动冰刀23沿第一方向转动时，能够更加轻松地剪碎冰块，延长了动冰刀23和定冰刀22的使用寿命。在转轴21带动动冰刀23沿第二方向转动时，动冰刀23的刀背带动冰块进行转动，并将冻结在一起的冰块送至冰块分离结构24处，将动冰刀23的刀背232设置成锯齿状后，动冰刀23在分离冻结在一起的冰块的过程中，若冰块沿动冰刀23的刀背进行滑动，锯齿状的刀背232的槽状结构可以对该冻结在一起的冰块的位置起到一定的限定作用，避免该冻结在一起的冰块在被分离过程中因受力出现滑动导致分离失败的情况。冰块分离结构24的一端与定冰刀22固定连接，另一端向背离定冰刀22的方向延伸，该向背离定冰刀22的方向延伸的一端为冰块分离装置的延伸端，延伸端的端部倾斜上翘，相对于延伸端的端部水平设置或向下倾斜设置的方式，冻结在一起的冰块在被分离时，延伸端的端部倾斜上翘的冰块分离结构24具有更高的分离成功率，冻结在一起的冰块在被分离时因受力出现滑动时，延伸端的端部倾斜上翘更能避免该冻结在一起的冰块脱离冰块分离结构24的情况。
进一步地，参考图8所示，冰块分离结构24在沿转轴21的径向方向上与储冰桶5的内壁之间具有间隙d，且该间隙d不允许独 立的冰块通过。冰块分离结构24远离转轴21的端面与储冰桶5的内壁之间具有间隙d，该间隙d用以方便冰块分离结构24的安装或更换。由于该间隙d不允许独立的冰块通过，因此尺寸大于独立的冰块的冰块也无法通过间隙d，这就使得冻结在一起的冰块在被定冰刀23转动时带动到间隙d附近，也不能越过该冰块分离装置24而直接沿储冰桶5的内壁从间隙d中滑落至整冰的出口处，能够运动至整冰的出口处的冰块均为被分离开来的冰块，不会堵塞出整冰的出口处，保证了该碎冰装置的正常运转。
进一步地，参考图11所示，储冰桶5内设有定冰刀22的一侧的底部设置有出冰漏斗(图中未示出)，设有冰块分离结构24的一侧的底部设置有出冰门51。冰块在储冰桶5内被冰刀组件转动时带动旋转会产生一定的离心力，带有该离心力的冰块在飞出时方向不定，设置有该出冰门51后，带有离心力的冰块先落在出冰门51上，然后沿该出冰门51滑出，避免带有离心力的冰块直接从储冰桶5中飞出落在取用冰块的容器外侧甚至砸伤附近的人或物。
参考图13所示，本发明还提出一种冰箱，该冰箱的冰箱门100的内壁设有制冰机，制冰机内设有上述碎冰装置200，使得制冰装置制备完成后储存在储冰桶内的冰块得到了充分的搅拌，该具有制备冰块功能的冰箱能够保证制备好的冰块不会冻结在一起，便于用户在需要时能够及时取用冰块。且该冰箱在冰块冻结时的碎冰能力也大大增强，方便使用。同时，该冰箱既能够在碎冰模式下使动冰刀23沿第一方向转动时与定冰刀22配合将冰块剪碎，也能够在冰块模式下动冰刀23沿与第一方向相反的第二方向转动时，通过动冰刀23与冰块分离结构24的配合将冻结在一起的冰块分离开来，是被分离后的冰块能够通过整冰的出口处，从而便于人们在直接使用冰块模式的情况下能够顺利取用到冰块。
由于在本实施例的冰箱中使用的碎冰装置与上述碎冰装置的各实施例中提供的碎冰装置相同，因此二者能够解决相同的技术问题，并达到相同的预期效果。
关于本发明实施例的冰箱的其他构成等已为本领域的技术人员所熟知，在此不再详细说明。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
