具体实施方式
下面结合附图对本公开的一些实施例提供的冰箱进行详细描述。
在本公开的描述中，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“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公开和简化描述，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公开的限制。
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。在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上。
请参阅图1和图2，本公开的一些实施例提供了一种冰箱100。该冰箱100包括：冷冻室1和制冰装置2。冷冻室1的温度低于零摄氏度，制冰装置2设置在冷冻室1内。此处，制冰装置2采用可抽拉的方式设置在冷冻室1内，这样可以提高冷冻室1内的空间利用率。
在一些示例中，请参阅图1和图2，冰箱100还包括：储冰盒3，该储冰盒3设置在冷冻室1内，且位于制冰装置2的下方，以便于接收并存储从制冰装置2落入储冰盒3内的冰。
在一些实施例中，请参阅图3～图7，上述制冰装置2包括：支架21、并行排列的多个制冰盒22、连杆转轴23和摆动件24。
在一些示例中，请参阅图5和图6，上述多个制冰盒22中的每个制冰盒22包括盒体221以及与盒体221连接的驱动轴222和铰接轴223。驱动轴222和铰接轴223相互平行(也即驱动轴222的轴线和铰接轴223的轴线相互平行)。每个制冰盒22通过对应的铰接轴223铰接在支架21内， 这样使得每个制冰盒22能够以对应的铰接轴223为定点，绕对应的铰接轴223在支架21内转动。
此处，支架21的结构包括多种。示例性的，请参阅图5，支架21包括矩形框架，该矩形框架呈环状设置。相应的，每个盒体221的形状为矩形或正方形等。这样可以在支架21内设置多个盒体221，提高支架21所占空间的利用率以及冰箱100的空间利用率。
上述驱动轴222和铰接轴223与对应的盒体221之间的连接方式包括多种。示例性的，驱动轴222采用固定连接的方式或可拆卸连接的方式连接在对应的盒体221上；铰接轴223采用固定连接的方式或可拆卸连接的方式连接在对应的盒体221上。由于制冰盒22需要在制冰位置和脱冰位置之间旋转，且驱动轴222和铰接轴223发生故障、需要更换的概率很小，所以驱动轴222和铰接轴223通常采用固定连接方式与对应的盒体221连接。
铰接轴223包括多种结构。示例性的，请参阅图3～图5，铰接轴223包括第一铰接轴2231和第二铰接轴2232。第一铰接轴2231位于对应的盒体221的第一侧(如图5中所示盒体221的左上侧)和矩形框架的第一边框(如图5中所示支架21的左上侧边框)之间，第二铰接轴2232位于对应的盒体221的第二侧(如图5中所示盒体221的右下侧)和矩形框架的第二边框(如图5中所示支架21的右下侧边框)之间。此处，第一侧与第二侧相对，且第一边框与第二边框相对，第一铰接轴2231的轴线和第二铰接轴2232的轴线重合，这样可以为每个盒体221提供两个相对的点支撑，提高每个制冰盒22绕对应的第一铰接轴2231的轴线转动的稳定性。
在一些示例中，请参阅图3～图5以及图7和图8，上述连杆转轴23包括相互平行且间隔设置的转动轴231和摆动轴232，以及连接转动轴231和摆动轴232的连接段233，连杆转轴23通过转动轴231铰接于支架21上。示例性的，请参阅图5，支架21上设置有第一孔211，转动轴231可以穿过第一孔211，使得连杆转轴23能够以第一孔211为定点转动。
上述连接段233的结构例如为板状结构或条状结构等。上述转动轴231和摆动轴232相互平行且间隔设置，指的是转动轴231的轴线和摆动轴232的轴线相互平行，转动轴231和摆动轴232分别位于连接段233的相对两端，且分别位于连接段233的相对两个侧面上。连接段233具有一定的刚性，这样可以使得转动轴231和摆动轴232之间的相对距离基本保持不变。
在一些示例中，请参阅图3～图7，上述摆动件24包括本体241以及设置在本体241上的铰接孔242和多个支撑部243，上述摆动轴232安装在铰接孔242内，每个制冰盒22的驱动轴222安装在对应的支撑部243上，使得摆动件24可摆动地连接于支架21和所述多个制冰盒22之间。
上述本体241的整体形状呈片状或板状，这样可以减小本体241所占用的空间，还可以减少本体241在摆动过程中的摆动阻力，使本体241的摆动较为顺畅。本体241的结构例如为镂空结构，这样可以减轻本体241的重量。
此外，本体241具有一定的刚度，这样在摆动件24摆动的过程中，可以避免发生变形，进而能够使得安装在摆动件24上的摆动轴232和多个驱动轴222之间的相对距离基本保持不变。
采用上述制冰装置2制冰后的脱冰过程为：向转动轴231施加一使得转动轴231转动的驱动力，则转动轴231带动摆动轴232转动，进而摆动轴232通过铰接孔242带动摆动件24摆动。在摆动件24摆动的过程中，会带动安装在其多个支撑部243上的多个驱动轴222分别绕对应的铰接轴223转动。由于每个驱动轴222分别与对应的盒体221连接，这样在每个驱动轴222绕对应的铰接轴223转动的过程中，会带动各制冰盒22分别绕对应的铰接轴223转动，进而带动各制冰盒22从制冰位置旋转至脱冰位置，完成所有制冰盒22的一次性脱冰。
为便于本领域的技术人员更好地理解本公开的内容，下面对冰箱100中使用的制冰装置2的各个制冰盒22的转动原理进行示意性说明。此处以制冰装置2包括三个制冰盒22为例。
图3～图7中所示的制冰装置2的各制冰盒22、连接转轴23和摆动件24可以等效为如图18所示的结构，该结构是用户站在面对制冰盒22的包括有驱动轴222和铰接轴223的表面观察而得到的。例如，用户的位置是如图4中所示的眼睛的位置。
请参阅图18，面对制冰盒22的包括有驱动轴222和铰接轴223的表面，左侧的制冰盒22为第一个制冰盒，中间的制冰盒22为第二个制冰盒，右侧的制冰盒22为第三个制冰盒。第一个制冰盒的驱动轴222等效为A1、铰接轴223等效为B1，第二个制冰盒的驱动轴222等效为A2、铰接轴223等效为B2，第三个制冰盒的驱动轴222等效为A3、铰接轴223等效为B3。摆动轴232等效为O1，转动轴231等效为P1。B1、B2、B3以及P1仅具 有旋转自由度，A1、A2、A3以及O1既具有旋转自由度，又具有平移自由度。将A1-B1-P1-O1依次首尾相接，基于P1和O1之间的相对距离基本保持不变，A1和B1以及B1和P1之间的相对位置关系基本保持不变，这样使得A1-B1-P1-O1构成了一个四连杆机构。类似地，A2-B2-P1-O1和A3-B3-P1-O1分别构成了一个四连杆机构。
请参阅图19，在一个四连杆机构中，固定不动的杆AD称为机架，与机架AD分别相连的杆AB和CD称为连架杆，不与机架相连的杆BC称为连杆。如图19中的虚线所示，在以连架杆CD作为主动件进行顺时针旋转的情况下，若连架杆CD带动连架杆AB和连杆BC运动到一条直线上(不考虑各个杆本身的重力影响)，则作用在连杆BC和作为从动件的连架杆AB上的力矩为0，此时连架杆AB和连杆BC不能继续运动。连架杆AB和连杆BC运动到一条直线上的位置称为死点位置。
在如图18中所示的等效的四连杆机构中，以第一个制冰盒为例，连线P1-B1在实际结构中为支架1的一部分，起到机架的作用；连线P1-O1在实际结构中为连接段233，起到连架杆的作用；连线A1-B1在实际结构中为第一个制冰盒的一部分，起到连架杆的作用；连线O1-A1在实际结构中为摆动件24的一部分，起到连杆的作用。第二个制冰盒和第三个制冰盒的情形与此类似。
在P1、O1以及B1(或B2、B3)位置确定的情况下，可以配置A1(或A2、A3)的位置，以使得在每个制冰盒22从制冰位置转动到脱冰位置的过程中，A1(或A2、A3)和B1(或B2、B3)之间的连线A1-B1(或A2-B2、A3-B3)能够绕B1(或B2、B3)旋转，并在第一次到达P1和B1(或B2、B3)之间的连线P1-B1(或P2-B2、P3-B3)前停止。当然，也可以配置B1(或B2、B3)的位置、或者P1和O1的位置。这样，可以避免四连杆机构位于死点位置，也即可以避免每个制冰盒22从制冰位置转动到脱冰位置的过程中出现转动不顺畅或甚至卡死的情况。
在一些示例中，在制冰盒22位于制冰位置的情况下，制冰盒22所在平面与制冰盒22的重力方向垂直或趋近于垂直。也就是说，制冰盒22的制冰位置为制冰盒22处于水平面的位置或处于趋近于水平面的位置。在制冰盒22位于脱冰位置的情况下，制冰盒22所旋转的角度大于或等于90°，以便于制冰盒22内的冰能够从制冰盒22内脱落。
示例性的，以P1-O1为主动件，发明人希望将A1-B1设计为在顺时针 方向上旋转至少90°的情况下，能够在第一次到达P1-B1前停止；将A2-B2设计为在顺时针方向上旋转至少90°的情况下，能够在第一次到达P1-B2前停止；将A3-B3设计为在顺时针方向上旋转至少90°的情况下，能够在第一次到达P1-B3前停止。这样，可以避免四连杆机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1在转动的过程中位于死点位置，提高四连杆机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1的转动性能以及转动的顺畅性。例如，可以将A1的位置设置在A1＇处，将A2的位置设置在A2＇处，并将A3的位置设置在A3＇处。
本公开的一些实施例提供的冰箱100中的制冰装置2，通过设置连杆组件23、摆动件24以及多个制冰盒22，利用连杆转轴23的连接段233连接转动轴231和摆动轴232，并固定转动轴231和摆动轴232之间的相对距离，利用摆动件24连接摆动轴232和各制冰盒22的驱动轴222，并固定摆动轴232和各驱动轴222之间的相对距离，使得连杆转轴23通过摆动件24带动多个制冰盒22同时转动的过程中，转动轴231、摆动轴232、各驱动轴222以及对应的各铰接轴223之间的距离保持不变，构成多个四连杆机构。而且，本公开的一些实施例在此基础上，通过配置转动轴231的位置，或配置摆动轴232的位置，或配置各驱动轴222的位置，或配置各铰接轴223的位置，使得每个制冰盒22从制冰位置转动到脱冰位置的过程中，每个驱动轴222和对应的铰接轴223之间的连线绕对应的铰接轴223旋转，并在第一次到达转动轴231和对应的铰接轴223之间的连线前停止，这样可以避免每个制冰盒22在转动到脱冰位置的过程中遇到死点位置，进而避免出现制冰盒22转动不顺畅甚至卡死的情况，提高制冰盒22的转动性能和顺畅性。
在一些实施例中，每个制冰盒22的驱动轴222的轴线和铰接轴223的轴线所确定的平面，均平行于摆动轴232的轴线与转动轴231的轴线所确定的平面。并且，每个制冰盒22的驱动轴222的轴线与铰接轴223的轴线之间的距离等于摆动轴232的轴线与转动轴231的轴线之间的距离。这也就意味着摆动轴232和转动轴231以及每个制冰盒22中的驱动轴222和铰接轴223所构成的四连杆机构为平行四边形机构。摆动轴232和转动轴231以及多个制冰盒22中的驱动轴222和铰接轴223共同构成共边多联平行四连杆机构。
此处，请参阅图18和图19，从图中可以看出，平行四边形机构的一 连架杆带动连杆和另一连架杆转动的过程中，另一连架杆在到达死点位置之前的可转动角度趋近于180°，而普通的四连杆机构的一连架杆带动连杆和另一连架杆转动的过程中，另一连架杆在到达死点位置之前的可转动角度与180°相差较多。由此，通过将摆动轴232和转动轴231以及每个制冰盒22中的驱动轴222和铰接轴223所构成的四连杆机构设置为平行四边形机构，可以增大每个制冰盒22在到达死点位置前的可转动角度范围，并提高各个制冰盒22的同步转动的稳定性。
需要注意的是，在如图18中所示的3个平行四边形机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1中，A1、A2、A3、B1、B2和B3位于多个制冰盒22所确定的平面内(例如为水平面内)，P1在竖直方向上的位置高于B1、B2和B3，并且在以如图4所示的位置观察时，A1位于B1的左侧，A2位于B2的左侧，A3位于B3的左侧。可以将这样的设计称为基础设计。从图18可以看出，在该基础设计下，若以P1-O1为主动件、并且使其绕顺时针旋转，A1-B1在转过90°后不会达到P1-B1的位置，也即第一制冰盒从制冰位置旋转到脱冰位置的过程中，不会遇到死点位置。但是，A2-B2在转过小于90°的角度后，就会到达P1-B2的位置，也即第二制冰盒在未旋转至脱冰位置就会遇到死点位置。同样地，A3-B3在转过小于90°的角度后，就会到达P1-B3的位置，也即第三制冰盒在未旋转至脱冰位置就会遇到死点位置。
由此，如图18中所示的基础设计在多个制冰盒22从制冰位置旋转到脱冰位置的过程中，可能会产生多个制冰盒22运动不顺畅的问题。为此，本公开的一些实施例提供了一种基于上述基础设计的另一设计，以使得多个制冰盒22从制冰位置旋转到脱冰位置的过程中，每个制冰盒22的驱动轴222和对应的铰接轴223之间的连线能够在第一次到达转动轴231和对应的铰接轴223之间的连线前停止。
请参阅图20，所述基础设计中的3个平行四边形机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1，在作为主动件的P1-O1顺时针旋转大致90°时，平行四边形机构A2-B2-P1-O1和A3-B3-P1-O1有可能会遇到死点位置，导致多个制冰盒22的旋转不顺畅。
由此，在一些实施例中，请参阅图20和图21，本公开的一些实施例基于上述基础设计提供的一种另一设计如下所示。
在每个制冰盒22位于制冰位置的情况下，沿制冰盒22的底面指向其 顶面的方向(垂直或趋近于垂直水平面的方向)，转动轴231位于铰接轴223的上方，且在每个制冰盒22的包括有驱动轴222和铰接轴223的表面中，驱动轴222位于对应的铰接轴223的左上方。
此处，制冰盒22的底面为盒体221的底面，制冰盒22的顶面为盒体221的顶面。
转动轴231位于铰接轴223的上方的具体位置包括多个，本公开的一些实施例对此不做限定，根据实际需要选择设置。例如，转动轴231位于铰接轴223的上方，且位于第一个制冰盒22的铰接轴223和第二个制冰盒22的铰接轴223之间(如图20所示)，或位于第二个制冰盒22的铰接轴223和第三个制冰盒22的铰接轴223之间(如图21所示)。
驱动轴222位于对应的铰接轴223的左上方，包括：沿制冰盒22的底面指向其顶面的方向，驱动轴222位于对应的铰接轴223的左侧，且位于对应的铰接轴223和转动轴231之间，或与转动轴231位于同一水平面，或位于转动轴231的上方。也就是说，每个驱动轴222不会位于对应的铰接轴223的正上方，每个驱动轴222的轴线与对应的铰接轴223的轴线所确定的平面与多个制冰盒22所确定的平面(例如为多个制冰盒22的顶面)之间的夹角为锐角。需要说明的是，驱动轴222的轴线与对应的铰接轴223的轴线所确定的平面与多个制冰盒22的顶面之间的夹角为任何值均在本发明保护的范围之内，例如10°、15°、27°、45°、60°、75°、86°等。
如图20和图21中所示，将第一个制冰盒的驱动轴222等效为A*1，第二个制冰盒的驱动轴222等效为A*2，第三个制冰盒的驱动轴222等效为A*3，摆动轴232等效为O*1。从图20和图21中可以看出，作为主动件的P1-O*1沿顺时针的方向旋转大致90°后，3个平行四边形机构A*1-B1-P1-O*1、A*2-B2-P1-O*1和A*3-B3-P1-O*1不会遇到死点位置。由此，各制冰盒22在旋转90°或更多以从制冰位置旋转到脱冰位置，能够避免遇到死点位置，从而会使得各制冰盒22的旋转过程更加顺畅。
此外，上述设计相比基础设计，在旋转多个制冰盒22的过程中，上述设计更为省力。下面详细说明。
请参阅图20，对于基础设计而言，在三个制冰盒22同步旋转过程中的初始时刻，A3的运动方向v、受力方向F和运动法线方向f均如图20中所示，受力方向F与运动方向v所夹的锐角为压力角a2，受力方向F与 运动法线方向f间的夹角为传动角r2。在如图20所示的设计中，B1、B2和B3位置不变，沿竖直方向，A*1的位置位于P1和B1之间，A*2的位置位于P1和B2之间，A*3的位置均位于P1和B3之间。例如，沿竖直方向，A*1与B1到相应的制冰盒22的顶面的距离不同，而基础设计中A1与B1到相应制冰盒22的顶面的距离相同，其他制冰盒22也是如此。在三个制冰盒22同步旋转过程中的初始时刻，A*3的运动方向v、受力方向F、受力方向的反方向-F、运动法线方向f、压力角a1和传动角r1均如图20所示，从图20中明显得到：压力角a1小于压力角a2，传动角r1大于传动角r2，通过减小压力角，就可提高驱动轴A*3的传动性能，进而使第三个制冰盒22的旋转更加省力，而且也更加顺畅。
此外，沿竖直方向，在A*1的位置位于P1和B1之间、A*2的位置位于P1和B2之间以及A*3的位置均位于P1和B3之间的情况下，可以调整O*1的位置，以调整压力角a1的大小，进而可以使得压力角a1尽可能的小，以有效提高各制冰盒22的旋转的顺畅性，并使得各制冰盒22的旋转更为省力。
图20仅对三个制冰盒22的运动进行分析，若制冰盒22的个数为四个或四个以上，距离摆动件24的摆动轴232较远的制冰盒22的压力角相比基础设计减小程度会更加明显，这样不仅可以避免出现制冰盒22不能旋转，甚至卡死的现象，提高制冰盒22的转动性能，还能够使这些制冰盒的旋转更加省力。而且，设置多个制冰盒22，还可以在一次性取冰的过程中取出较多的冰，有效提高了取冰效率。
各制冰盒22的驱动轴222的轴线与铰接轴223的轴线所确定的平面与多个制冰盒22所确定的平面之间的夹角相等，这样可以使得多个制冰盒22在旋转的过程中，能够基本保持同步旋转，提高多个制冰盒22的旋转的稳定性。
本公开提供的一些实施例中，上述基础设计还具有多个变型设计。
在一些实施例中，本公开提供的一种变型设计如图22所示。请参阅图22，图中所示的3个平行四边形机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1中，A1、A2、A3、B1、B2和B3位于多个制冰盒2所确定的平面内(例如为水平面内)，P1在竖直方向上的位置高于B1、B2和B3，并且在以如图4所示的位置观察时，A1位于B1的右侧，A2位于B2的右侧，A3位于B3的右侧。
从图22中可以看出，在上述变型设计中，若以P1-O1为主动件、并且使其沿顺时针方向旋转，A1-B1在转过90°后不会达到P1-B1的位置，也即第一制冰盒从制冰位置旋转到脱冰位置的过程中，不会遇到死点位置。但是，A2-B2在转过小于90°的角度后，就会到达P1-B2的位置，也即第二制冰盒在未旋转至脱冰位置就会遇到死点位置。同样地，A3-B3在转过小于90°的角度后，就会到达P1-B3的位置，也即第三制冰盒在未旋转至脱冰位置就会遇到死点位置。
由此，如图22中所示的变型设计，在多个制冰盒22从制冰位置旋转到脱冰位置的过程中，可能会产生多个制冰盒22运动不顺畅的问题。为此，本公开的一些实施例提供了一种基于上述变型设计的另一设计。
请参阅图22，本公开的一些实施例基于上述变型设计提供的另一设计如下所示。
在每个制冰盒22位于制冰位置的情况下，沿制冰盒22的底面指向其顶面的方向(垂直或趋近于垂直水平面的方向)，转动轴231位于铰接轴223的上方，且在每个制冰盒22的包括有驱动轴222和铰接轴223的表面中，驱动轴222位于铰接轴223的右下方。此处，每个驱动轴222不会位于对应的铰接轴223的正下方。
如图22中所示，将第一个制冰盒的驱动轴222等效为A*1，第二个制冰盒的驱动轴222等效为A*2，第三个制冰盒的驱动轴222等效为A*3，摆动轴232等效为O*1。从图22中可以看到，作为主动件的P1-O*1沿顺时针的方向旋转大致90°后，3个平行四边形机构A*1-B1-P1-O*1、A*2-B2-P1-O*1和A*3-B3-P1-O*1不会遇到死点位置。由此，各制冰盒22在旋转90°或更多以从制冰位置旋转到脱冰位置，能够避免遇到死点位置，从而会使得各制冰盒22的旋转过程更加顺畅。
在另一些实施例中，本公开提供的另一种变型设计如图23所示。请参阅图23，图中所示的3个平行四边形机构A1-B1-P1-O1、A2-B2-P1-O1和A3-B3-P1-O1中，A1、A2、A3、B1、B2和B3位于多个制冰盒22所确定的平面内(例如为水平面内)，P1在竖直方向上的位置低于B1、B2和B3，并且在以图4所示的位置观察时，A1位于B1的左侧，A2位于B2的左侧，A3位于B3的左侧。
从图23中可以看出，在上述变型设计中，若以P1-O1为主动件、并且使其沿逆时针方向旋转，A1-B1在转过90°后不会达到连线P1-B1的 位置，也即第一制冰盒从制冰位置旋转到脱冰位置的过程中，不会遇到死点位置。但是，A2-B2在转过小于90°的角度后，就会到达P1-B2的位置，也即第二制冰盒在未旋转至脱冰位置就会遇到死点位置。同样地，A3-B3在转过小于90°的角度后，就会到达P1-B3的位置，也即第三制冰盒在未旋转至脱冰位置就会遇到死点位置。
由此，如图23所示的变型设计中，在多个制冰盒22从制冰位置旋转到脱冰位置的过程中，可能会产生多个制冰盒22运动不顺畅的问题。为此，本公开的一些实施例提供了一种基于上述变型设计的另一设计。
请参阅图23，本公开的一些实施例基于上述变型设计提供的另一设计如下所示。
在每个制冰盒22位于制冰位置的情况下，沿制冰盒22的底面指向其顶面的方向(垂直或趋近于垂直水平面的方向)，转动轴231位于铰接轴223的下方，且在每个制冰盒22的包括有驱动轴222和铰接轴223的表面中，驱动轴222位于铰接轴223的左下方。此处，每个驱动轴222不会位于对应的铰接轴223的正下方。
如图23中所示，将第一个制冰盒的驱动轴222等效为A*1，第二个制冰盒的驱动轴222等效为A*2，第三个制冰盒的驱动轴222等效为A*3，摆动轴232等效为O*1。从图23中可以看到，作为主动件的P1-O*1沿逆时针方向旋转大致90°后，3个平行四边形机构A*1-B1-P1-O*1、A*2-B2-P1-O*1和A*3-B3-P1-O*1不会遇到死点位置。由此，各制冰盒22在旋转90°或更多以从制冰位置旋转到脱冰位置，能够避免遇到死点位置，从而会使得各制冰盒22的旋转过程更加顺畅。
在了解制冰装置2的各个制冰盒22的上述转动原理的基础上，可以通过相应的结构设计，获得制冰装置2中各个零部件的形状和构造。本公开一些实施例以图20所示的转动原理(与图7相对应)为例，提供了冰箱100中的一种制冰装置2。该制冰装置2的整体结构如图3～图17所示，下面将对该制冰装置2的结构进行示例性的描述。
在一些实施例中，请参阅图10，制冰装置2中的摆动件24的多个支撑部243位于本体241的下方，铰接孔242位于本体241的中部区域，沿竖直方向，铰接孔242位于每个支撑部243的上方。这样可以使得与铰接孔243连接的摆动轴232位于多个驱动轴222的上方，基于驱动轴222位于对应的铰接轴223的上方，会使得每个支撑部243也位于对应的铰接轴 223的上方，这样在多个制冰盒22从制冰位置旋转至脱冰位置的过程中，避免多个支撑部243产生运动干涉，使得多个制冰盒22的旋转更为顺畅。
上述多个支撑部243的结构包括多种。示例性的，多个支撑部243包括以下至少一种：弧形槽、U形槽或通孔。此处，弧形槽或U形槽例如为图10中所示的结构。上述多个支撑部243的结构采用结构较为简单的弧形槽或U形槽，可以使摆动件24的加工工艺较为简单，且便于对多个驱动轴222进行安装或拆卸。上述多个支撑部243的结构采用通孔，可以避免多个驱动轴222从对应的支撑部243内脱落。
此处，在摆动件24摆动，并带动安装在多个支撑部243上的多个驱动轴222分别绕对应的铰接轴223转动的过程中，制冰盒22可能会沿驱动轴222的轴向产生晃动，也就会使得驱动轴222在沿其自身轴向的方向产生位移。
在一些实施例中，请参阅图5和图6，每个制冰盒22还包括限位块224，该限位块224设置在对应的驱动轴222的背离对应的盒体221的一端，且该限位块224配置为限制对应的驱动轴222沿其自身的轴线方向的位移。在将每个驱动轴222安装到对应的支撑部243上后，限位块224位于摆动件24的背离制冰盒22的一端，这样在驱动轴沿指向盒体221的方向移动(也即制冰盒22沿背离摆动件24的方向移动)的过程中，可以通过限位块224限定驱动轴222的位移，进而防止制冰盒22从摆动件24上脱离。
限位块224与对应的驱动轴222的连接方式包括多种，且该连接方式与支撑部243的结构相配合。示例性的，若支撑部243的结构采用弧形槽或U形槽，则限位块224采用固定连接的方式或可拆卸连接的方式与对应的驱动轴222连接。若支撑部243的结构采用通孔，则限位块224采用可拆卸连接的方式与对应的驱动轴222连接。
在一些实施例中，摆动件24与摆动轴232之间的连接包括多种。
在一些示例中，摆动轴232固定安装在摆动件24上。例如，摆动轴232固定安装在摆动件24的铰接孔242内。
在另一些示例中，摆动轴232可拆卸地连接在摆动件24上。这样便于连杆转轴23和摆动件24之间的安装和拆卸。
示例性的，请参阅图10～图14，摆动件24还包括设置在本体241上的安装孔244和开口245，安装孔244和铰接孔242通过开口245相连通。安装孔244的孔径分别大于铰接孔242的孔径和摆动轴232的直径，开口 245沿垂直于安装孔244的中心与铰接孔242的中心连线的方向上的尺寸L2小于摆动轴232的直径。此处，开口245沿平行于安装孔244的中心与铰接孔242的中心连线的方向上的尺寸大于或等于0。
请参阅图8和图9，摆动轴232包括扁位段2321，扁位段2321的厚度L1小于开口沿垂直于安装孔244的中心与铰接孔242的中心连线的方向上的尺寸L2，以使得扁位段2321能够通过开口245由安装孔244进入铰接孔242。
请继续参阅图10～图14，在摆动轴232的安装过程中，先将摆动轴232插入安装孔244内，转动摆动轴232，使得摆动轴232在扁位段2321的作用下，将摆动轴232移动至铰接孔242，之后再次转动摆动轴232，使得摆动轴232卡在铰接孔242内，避免摆动轴232由于扁位段2321的作用从铰接孔242内脱出。
在一些实施例中，请参阅图8、图12以及图14，连杆转轴23还包括凸沿234，该凸沿234设置在摆动轴232的远离连接段233的一端，凸沿234的最大尺寸大于铰接孔242的孔径，且小于安装孔244的孔径。
凸沿234的形状包括多种。示例性的，凸沿234的形状包括圆形、椭圆形、正方形或长方形等。凸沿234的最大尺寸与凸沿234的形状相关。示例性的，凸沿234的形状为圆形，则最大尺寸为该圆形的直径；凸沿234的形状为椭圆形，则最大尺寸为该椭圆形的长轴尺寸；凸沿234的形状为正方形或长方形，则最大尺寸为该正方形或长方形的对角线的尺寸。
通过将凸沿234的最大尺寸设置为大于铰接孔242的孔径，且小于安装孔244的孔径，可以在摆动轴232与摆动件24为可拆卸的连接的情况下，确保凸沿234能够通过安装孔244，且在摆动轴232位于铰接孔242内后，限制摆动轴232沿其自身轴线方向的位移。
在一些实施例中，请参阅图15～图17，制冰装置2还包括：手动旋钮25，手动旋钮25设置在支架21的背离每个制冰盒22的一侧，且手动旋钮25与连杆转轴23的转动轴231连接。通过设置与转动轴231连接的手动旋钮25，可以通过转动手动旋钮25使得转动轴231转动，进而使多个制冰盒22转动，相比通过转动轴231转动以使多个制冰盒22转动，更为省力。
此处，制冰装置2还可以采用电动旋钮与转动轴231连接。
在一些示例中，手动旋钮25与转动轴231的连接为直接连接。
在另一示例中，手动旋钮25与转动轴231的连接为间接连接。请继续参阅图15～图17，连杆转轴23还包括固定段235，该固定段235与转动轴231的远离连接段233的一端连接，手动旋钮25安装在固定段235上。
上述固定段235包括卡槽2351，手动旋钮25包括安装槽251，以及设置在安装槽251内且与卡槽2351相配合的卡扣252。这样可以使得固定段235与手动旋钮25之间的连接较为稳固。
此外，在安装槽251内设置有滑台，固定段235上设置有与滑台相配合的滑槽，这样可以使得固定段235更为紧固的安装在安装槽25内，避免旋转手动旋转25的过程中，固定段235与手动旋钮25发生相对位移。此外，手动旋钮25内开设有供转动轴231插入的安装孔，转动轴231的侧壁上开设有定位孔，在将转动轴231固定在安装孔后，采用定位销穿过手动旋钮25固定在定位孔内。这样可以进一步的固定转动轴231和手动旋钮25之间的连接此处，手动旋钮25上标识有旋转方向，以便于清楚显示多个制冰盒22从制冰位置到脱冰位置的所需旋转的方向。
在一些实施例中，请参阅图5，制冰装置2还包括多个复位件26，该多个复位件26配置为驱动多个制冰盒22从脱冰位置复位至制冰位置。
上述多个复位件26包括以下至少一种：扭簧或顶紧气缸。
在多个复位件26包括扭簧的情况下，扭簧套设在每个制冰盒22的铰接轴223上，扭簧的两个支臂分别与支架21和铰接轴223连接。这样在转动连杆转轴23使得每个制冰盒22从制冰位置旋转至脱冰位置后，扭簧会被压缩，停止向连杆转轴23施加力，每个制冰盒22能够在对应的扭簧的回复力的作用下，从脱冰位置旋转至制冰位置。扭簧的占用空间小，安装关系较为简单，且可以降低制冰装置2的制造成本。
在多个复位件26包括顶紧气缸的情况下，顶紧气缸的一端与每个制冰盒22的盒体221连接，另一端与支架21连接。这样在每个制冰盒22从制冰位置旋转至脱冰位置后，顶紧气缸会伸长，在需要将每个制冰盒22从脱冰位置旋转至制冰位置后，顶紧气缸会再缩短，将每个制冰盒22拉回至制冰位置。
在一些实施例中，带动多个制冰盒22同步旋转还可通过下述结构实现，结构包括：驱动电机、传动轴、传动轮以及传送带，传动轴与驱动电机的输出轴连接，传动轮安装在驱动轴222上，相邻两个制冰盒22上的传动轮通过传送带连接，在驱动电机工作的过程中，可以通过传送轮与传送 带相配合带动多个制冰盒22同步旋转。
在本公开的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本公开的具体实施方式，但本公开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公开揭露的技术范围内，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，本公开的保护范围应以所述权利要求的保护范围为准。
