具体实施方式
为了使本技术领域的人员更好地理解本发明中的技术方案，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，都应当属于本发明保护的范围。
参见图1至图3，本发明一实施方式提供冰箱，冰箱包括箱体以及用于开闭箱体的冰箱门体组件100。箱体内形成的储藏间室包括冷藏间室和冷冻间室。冰箱门体组件100可包括用于开闭 箱体的门体110，门体110可包括门壳和门衬，门壳和门衬之间可填充有隔热材料，隔热材料可为发泡材料。门体110可包括用于开闭冷藏间室的冷藏门体以及用于开闭冷冻间室的冷冻门体。
冰箱内可设置有制冰装置，冰箱的冷藏门体上可设置有制冰间室，制冰装置可安装在制冰间室内。冷藏门体上还可设置有储冰桶和分配器300。储冰桶可安装在制冰间室内部，并置于制冰装置下方，用于接收并存储来自制冰装置的冰。分配器300可包括出冰装置200，出冰装置200包括贯穿门体110的出冰通道210，出冰通道210可与储冰桶连通，用户可以使用分配器300在不打开冰箱门体110的情况下直接取出储冰桶内的冰。
当然，也可以在冷藏间室内部设置用于安装制冰装置的制冰间室，而在冷藏门体上设置储冰桶和分配器300，制冰装置的冰直接排放至冷藏门体上的储冰桶内通过分配器300排出。当然，制冰装置也可以设置在冷冻间室内或者冷冻门体上，分配器300设置在冷冻门体上。
在本发明一实施方式中，出冰装置200包括出冰通道210，出冰通道210可贯穿门体110，具有置于门衬一侧的进冰口211和置于门壳一侧与进冰口211相对的出冰口212。其中，进冰口211可与储冰桶连通。出冰口212处设置有盖板组件220以及驱动装置230。盖板组件220可开闭出冰口212，驱动装置230与盖板组件220的驱动轴223连接以驱动盖板组件220转动。驱动装置230可包括电机以及传动组件，驱动装置230可安装在分配器300的分配器壳体310的侧壁上。
冰箱门体110上可设置有用于控制驱动装置230的控制面板或者按键，用户可以通过控制面板或者按键控制取冰，并通过控制面板选择取冰冰量或者在冰量达到需求时主动控制结束取冰。
当用户发出取冰命令时，冰箱内的控制装置会启动驱动装置230的电机沿第一方向A运行以驱动盖板组件220转动打开出冰口212，取冰结束后，电机沿与第一方向A相反的第二方向转动以驱动盖板组件220关闭出冰口212。
出冰装置200还可包括限位结构，限位结构可限制盖板组件220的极限打开位置，当电机沿第一方向A转动驱动盖板组件200转动至与限位结构干涉位置时即为运动至极限打开位置。
出冰装置200可包括冰块引导通道250，冰块引导通道250可设置于出冰口一侧，冰箱门体110的外侧可设置有分配器凹部320，冰块引导通道250可位于分配器凹部320内。盖板组件200可置于冰块引导通道250内部，储冰桶内的冰经出冰通道从出冰口排出后进入冰块引导通道250内，并通过冰块引导通道250的出口排出。冰块引导通道250的壁面形成限位结构，盖板组件200旋转至极限打开位置时，盖板组件200与冰块引导通道250的壁面发生干涉。
参见图3至图5，盖板组件220包括支架221和密封盖222，支架221和密封盖222通过连接轴224连接。驱动装置230可与支架221的驱动轴223连接，驱动装置230可驱动支架221转动进而带动密封盖222转动。连接轴224可设置在支架221上，密封盖222上可设置有与连接轴224配合的连接孔225，连接轴224和连接孔225可间隙配合，由此，密封盖222可绕连接轴224的轴线摆动，当驱动组件驱动盖板组件220转动关闭出冰口212时，若由于公差或者一些其他原因，密封盖222与出冰口212未完全配合，或者密封盖222相对于出冰口212偏斜导致密封盖222的上侧或者下侧先接触出冰口212，驱动装置230驱动盖板组件220进一步旋转，在外力的作用下密封盖222能够自动绕连接轴224轻微摆动，将最先接触的一侧压入出冰口212内，使得密封盖222移动至最佳位置密封出冰口212。
在本实施方式中，密封盖222包括密封盖板2221，密封盖板2221与支架221连接，密封盖板2221上还安装有硅胶密封件2222，密封盖板2221与硅胶密封件2222之间形成的空间内填充有PE闭孔泡棉，从而能够阻挡冷气传递。密封盖222关闭出冰口212时，出冰口212的边缘抵压在硅胶密封件2222的表面上，硅胶密封件2222与出冰口212接触的表面可呈球形表面，从而能够提升密封效果。
密封盖222和支架221之间设置有弹性支撑件240，弹性支撑件240与密封盖222的接触位置241位于密封盖222远离驱动轴223一侧，连接轴224位于驱动轴223和接触位置241之间。
在本实施方式中，弹性支撑件240可以一端与支架221固定，另一端为自由端支撑在密封盖222上，也可以一端固定在密封盖222上，另一端为自由端支撑在支架221上，或者两端分别与 密封盖222和支架221连接。当然，也可以在支架221和密封盖222之间设置其他用于安装弹性支撑件240的结构。弹性支撑件240与密封盖222的接触点可以具有多个，但只要存在位于连接轴224远离驱动轴223一侧的接触位置241即可。
在本实施方式中，由于密封盖222可绕支架221的连接轴224摆动，在驱动装置230驱动盖板组件220转动的过程中，尤其当盖板组件220处于打开出冰口212的位置或者处于打开出冰口212的过程中时，由于密封盖222受到重力作用，密封盖222远离驱动轴223一侧具有倾斜的趋势，如此，使用弹性支撑件240支撑密封件，且弹性支撑件240与密封盖222的接触位置241设置在密封盖222远离驱动轴223一侧，且将连接轴224设置在驱动轴223和接触位置241之间，能够避免密封盖222在重力作用下绕连接轴224摆动，导致密封盖222远离驱动轴223一侧倾斜，进而导致关闭盖板组件220的过程中密封盖222远离驱动轴223一侧与出冰口212之间出现缝隙。
同时，弹性支撑件240具有弹性，在对密封盖222进行支撑的同时，又不会影响密封盖222的自由度。因而，密封盖222能够起到较好的密封效果。
进一步的，在本发明一实施方式中，密封盖222的重心位于接触位置241和驱动轴223之间。
在本实施方式中，连接轴224可设置与密封盖222的重心对应的位置，连接轴224也可设置在密封盖222的重心与驱动轴223之间。当连接轴224设置在密封盖222的重心与驱动轴223之间时，可将弹性支撑件240与密封盖222的接触位置241设置在密封盖222重心远离驱动轴223一侧，也就是，将密封盖222的重心设置在驱动轴223和接触位置241之间，如此，弹性支撑件240能够更好的避免密封盖222的偏斜，平衡密封盖222重力。
进一步的，在本发明一实施方式中，弹性支撑件240包括设置于支架221自由端一侧的弹性支撑肋226，弹性支撑肋226可与支架221一体成型，弹性支撑肋226的自由端支撑在密封盖222上。在本实施方式中，弹性支撑肋226自支架221的自由端向靠近驱动轴223一侧延伸。如此，在安装制造过程中，仅需将驱动装置230、支架221以及密封盖222装配即可，弹性支撑件240可自动支撑在合适的位置，而无需手动调整弹性支撑件240的位置。
进一步的，在本发明一实施方式中，连接轴224可设置在支架221上，密封盖222上可设置有与连接轴224配合的连接孔225，连接轴224可与连接孔225间隙配合，连接轴224可与密封盖222点接触。具体的，在本实施方式中，密封盖222上可设置有支撑肋226，支撑肋226与连接轴224呈角度设置，连接轴224支撑在支撑肋226上，连接轴224与支撑肋226之间呈点接触。当然也可以将连接轴224设置在密封盖222上，连接孔225和支撑肋226设置在支架221上。
在本实施方式中，支撑肋226呈阶梯状，包括第一支撑肋2261以及高于第一支撑肋2261的第二支撑肋2262，第一支撑肋2261与第二支撑肋2262的连接面为斜面，第一支撑肋2261与第二支撑肋2262的连接处位于所述密封盖222的中心，连接轴224支撑于第一支撑肋2261上且靠近第一支撑肋2261与第二支撑肋2262的连接处。
如此，密封盖222可绕连接轴224的支撑点在任意方向上摆动，当驱动装置230驱动盖板组件220关闭出冰口212时，无论密封盖222的任意一侧先接触出冰口212的侧壁，均能在外力作用下挤压密封盖222绕支撑肋226朝其他方向摆动，如密封盖222可沿连接轴224轴线方向移动，也可绕支撑肋226摆动，从而，在关闭盖板组件220时，密封盖222能够完全密封出冰口212。
进一步的，在本发明一实施方式中，连接轴224与支撑肋226垂直，连接轴224与支撑肋226的接触点位于密封盖222的中心轴线上。如此，能够使得密封盖222处于一个较为平衡的位置，密封盖222的密封效果更好。
本申请提供的出冰装置200，密封盖222具有一定的自由度，在密封盖222关闭出冰口212的过程中，可自动调节密封盖222的位置使其与出冰口212配合，同时，设置有用于支撑密封盖222的弹性支撑件240，又能够避免密封盖222在重力作用下产生偏斜，该出冰装置200整体密封效果好。
参见图3和图6，本发明一实施方式还提供一种出冰装置200控制方法，包括：
接收到打开出冰口212信号后，控制电机沿第一方向A运行以带动盖板组件220从关闭出冰口212的关闭位置向打开出冰口212的打开位置转动；
当电机运行第一预设转数时，控制电机关闭；
其中，电机为可自锁的电机，第一预设转数对应的旋转角度大于盖板组件220自关闭位置转动至极限打开位置的角度。
在本实施方式中，用户通过冰箱门体110上的控制面板或者按键下达取冰指令时，即为向冰箱内与出冰装置200对应的控制模块发送打开出冰口212信号，此时，电机转动带动盖板组件220打开出冰口212，冰块可从出冰通道210中滑出。
在本实施方式中，盖板组件220对应的驱动装置230中的电机为可自锁的电机，当电机不通电时，其具有自锁转矩可将盖板组件220锁定在关闭出冰口212的关闭位置或打开出冰口212的打开位置，无需在在盖板组件220的转轴上安装可辅助盖板组件220关闭的弹性元件提供关闭盖板组件220的锁紧力，同时也能将盖板组件220固定在打开位置。
在电机按照预定的程序运行时，可能会出现误差，电机转动带动盖板组件220实际转动的角度可能会小于理论上的角度，但由于可自锁的电机还具有临界锁紧转矩，当电机通电时，若受到的转矩小于临界锁紧转矩，则电机可带动盖板组件220转动，若盖板组件220受到干涉使得电机发生堵转，且堵转时长较长导致电机受到的转矩大于临界锁紧转矩，则电机不会继续带动盖板组件220转动，且盖板组件220会发生反向回弹。
如此，若在电机打开盖板组件220的过程中出现误差，比如少转了5转，但在驱动盖板组件220回复的过程中未出现误差，则盖板组件220在关闭时可能会出现堵转时长过长，使得电机受到的转矩大于临界锁紧转矩，导致盖板组件220沿第一方向A回弹，盖板组件220与出冰口212之间出现间隙，盖板组件220与出冰口212即使出现较小的间隙，也会导致凝露、漏冷等现象。
在本实施方式中，当电机沿第一方向A转动驱动盖板组件220打开出冰口212时，控制电机运行第一预设转数，其中，第一预设转数对应的旋转角度可为在电机转动过程中不出现误差的理论情况下，电机转动第一预设转数带动盖板组件220转动的角度。第一预设转数对应的旋转角度大于盖板组件220自关闭位置转动至极限打开位置的角度，可以理解为，若电机转动过程中不出现误差，则在电机沿第一方向A转动驱动盖板组件220打开时，当驱动盖板组件220转动至极限打开位置时，电机仍会继续转动。
第一预设转数对应的旋转角度与盖板组件220自关闭位置转动至极限打开位置的角度之差可在预设范围内，电机运行第一预设转数时，电机受到的转矩小于临界锁紧转矩。此外，及时电机在打开过程中发生堵转导致盖板组件220回弹，回弹范围也较小，对盖板组件220打开过程影响较小。
其中，在本实施方式中，盖板组件220关闭出冰口212的关闭位置可为盖板组件220与出冰口212接触的位置。但由于盖板组件220的密封盖222与出冰口212接触位置可弹性压缩，盖板组件220关闭出冰口212的关闭位置也可为盖板组件220关闭出冰口212后继续朝向出冰口212一侧运行至弹性形变一定量的位置。
如此，即使在电机沿第一方向A转动过程中出现误差，导致盖板组件220实际转动角度较小，但只要在合理误差范围内，盖板组件220都可运动至极限打开位置且堵转转矩不会大于临界锁紧转矩，进而不会影响盖板组件220的关闭，可避免电机驱动盖板组件220关闭出冰口212的过程中堵转较多导致出冰口212回弹。
进一步的，在本发明一实施方式中。所述出冰装置200控制方法还包括：
接收到关闭出冰口212信号后，控制电机沿第二方向运行以带动盖板组件220从打开位置向关闭位置转动；
当电机运行第二预设转数时，控制电机关闭。
其中，第二方向与第一方向A相反，第二预设转数对应的旋转角度大于盖板组件220自极限打开位置转动至关闭位置的角度。
在本实施方式中，电机转动带动盖板组件220打开出冰口212时，若电机不出现误差，则在电机驱动盖板组件220转动至关闭位置时会继续转动，以避免电机驱动盖板组件220关闭的过程中电机出现误差，导致盖板组件220关闭不到位。且当电机驱动盖板组件220自极限打开位置向 关闭位置旋转时，电机运行第二预设转数时，电机受到的转矩小于临界锁紧转矩，盖板组件220不会出现回弹。
同时，由于在开关盖板组件220的过程中电机运转第一预设步数消除误差，可避免盖板组件220关闭时实际可转动角度缩小，因此即使在关闭盖板组件220的过程中，电机转动对应的旋转角度大于盖板组件220自极限打开位置转动至关闭位置的角度，但在预设范围内，电机的堵转时长也不会过长，进而不会导致盖板组件220回弹，可实现较好的密封效果。
在本实施方式中，当接收到出冰口212打开信号时，还可记录预设时间段内的出冰口212打开次数和/或出冰口212打开时长，并根据预设时间段内的出冰口212打开次数和/或打开时长控制制冰间室的制冷开机点温度和制冷关机点温度。
当制冰间室内的温度大于制冷开机点温度时，控制制冷系统向制冰间室制冷，直至制冰间室的温度降低至制冷关机点温度。因此，若预设时间段内出冰口212打开次数大于预设次数和/或出冰口212打开时长大于预设时长，可判定用户对于冰的需求量较高，此时可对制冰间室匹配低制冷开机点温度和低制冷关机点温度，以将制冰间室的温度保持在低于预设温度的范围内，或者也可以增加制冰次数。相应的，若预设时间段内，出冰口212打开次数和/或出冰口212打开时长均较小，则可对制冰间室匹配高制冷开机点温度和高制冷关机点温度，或者，减少制冰装置的制冰次数。如此，可以根据出冰口212的打开数据判断用户习惯，并控制制冰系统的运行。
进一步的，在本发明一实施方式中，电机为步进电机，可通过控制电机步数控制电机的转数。所述出冰装置200控制方法具体包括：
接收到打开出冰口212信号后，控制电机以第一方向A运行第一预设步数时，控制电机关闭，第一预设步数对应的旋转角度大于盖板组件220关闭出冰口212的关闭位置旋转至极限打开位置的角度；
当接收到关闭出冰口212信号后，控制电机以第二方向运行第二预设步数时，控制电机关闭，第二预设步数对应的旋转角度大于盖板组件220自极限打开位置旋转至关闭位置的角度。
在本实施方式中，步进电机在运行过程中，可能会出现失步的现象，即电机实际运行的步数比理论的步数要少，相应的电机转动的转数以及驱动盖板组件220实际转动的角度均会小于理论值。
第一预设步数对应的旋转角度可为在电机运行中不出现失步等误差的理论情况下，电机运行第一预设步数可驱动盖板组件220转动的角度。同样的，第二预设步数对应的旋转角度可为电机在运行中不出现失步等误差的理论情况下，电机运行第二预设步数可驱动盖板组件220转动的角度。
如此，通过控制电机的的运行步数，使得电机在驱动盖板组件220打开的过程中能够运动至极限打开位置，从而不会缩小关闭盖板组件220时，盖板组件220可以运动的角度，避免在关闭盖板组件220时，盖板组件220与出冰口212干涉电机发生较长时间的堵转导致电机受到的转矩超过临界锁紧转矩，使盖板组件220发生回弹，盖板组件220无法密封出冰口212。
进一步的，参见图7，在本发明一实施方式中，所述出冰装置200控制方法中，步骤“控制所述电机以第一方向A运行第一预设步数时，控制所述电机关闭，”还包括：
当电机运行预设打开步数时，控制电机沿第一方向A继续运行；
当电机继续运行第一预设堵转步数时，控制电机关闭；
其中，第一预设步数为预设打开步数与第一预设堵转步数之和，预设打开步数对应的旋转角度等于盖板组件220自关闭出冰口212的关闭位置转动至极限打开位置的角度，第一预设堵转步数小于100。
在本实施方式中，预设打开步数对应的旋转角度可为在电机运行时不出现失步等误差的理论情况下，电机运行预设打开步数可带动盖板组价转动的角度。预设打开步数对应的旋转角度等于盖板组件220自关闭出冰口212的关闭位置转动至极限打开位置的角度可为，在电机不出现失步等误差的理论情况下，电机运行预设打开步数可带动盖板组件220自关闭位置运行至极限打开位置，此时电机继续运行第一预设堵转步数，盖板组件220会因极限打开位置处的限位结构的限制 发生堵转。而在电机实际运行过程中，电机可能出现失步，在运行预设打开步数后再运行第一预设堵转步数，可避免失步带来的影响。
其中，盖板组件220处于极限位置时，控制电机沿第一方向A继续运行第一预设步数，电机受到的转矩可小于临界锁紧转矩，第一预设堵转步数可小于100，在该步数范围内，电机即使发生堵转，也不会使得盖板组件220产生回弹。
进一步的，在本发明一实施方式中，第二预设步数可为预设关闭步数与第二预设堵转步数之和。预设关闭步数可等于预设打开步数之和，第二预设堵转步数可与第一预设堵转步数不同。预设关闭步数对应的旋转角度可等于盖板组件220自极限打开位置旋转至关闭位置的角度，也就是，在电机不出现失步等误差的理论情况下，电机运行预设关闭步数时，带动盖板组件220从极限打开位置恰好运行至关闭位置。
本发明的一具体示例如，若盖板组件220自关闭出冰口212的关闭位置转动到极限打开位置的旋转角度为45°，第二预设步数可为990步，预设打开步数和预设关闭步数为950步，第二预设堵转步数可为40步。其中，在电机不出现失步等误差的理论情况下运行时，电机运行950步可带动盖板组件220转动45°。
若在打开过程中不设置第一预设堵转步数，电机仅沿第一方向A运行950步，仅在关闭过程中设置堵转步数，电机沿第二方向运行990步，若电机在打开过程中发生失步，而关闭过程中不出现失步，如在打开过程中失步30步，则在关闭盖板组件220过程的过程中，电机的实际堵转步数为70步，可能导致盖板组件220回弹，出冰口212密封不严。
而在本发明一实施方式中，在电机沿第一方向A运行时设置第一堵转步数，如第一堵转步数为50步，则电机沿第一方向A运行950步后需继续沿第一方向A运行50步，如此，即使在电机驱动盖板组件220打开的过程中出现失步，如失步30步，电机仍可带动盖板组件220打开到极限打开位置，盖板组件220的关闭过程不会受到打开过程中电机失步的影响。
参见图8，本发明一实施方式还提供一种出冰装置200，包括存储器202和处理器201，存储器202和处理器201通过通信总线204通信连接。存储器202上存储有可在处理器201上运行的计算机程序，所述处理器201执行所述计算机程序时，实现上述实施方式中的冰箱控制方法中的步骤。出冰装置还包括与通信总线204连接的通信接口203，用于与出冰装置200的其他设备通信。
本发明一实施方式还提供一种计算机可读存储介质，其上存储有计算机程序，所述计算机程序被处理器执行时，实现上述实施方式中的出冰装置控制方法中的步骤。
