应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
如图1-4所示，本发明一实施方式公开了一种制冰机。所述制冰机1包括：框架100、制冰盘200、防溅水挡板300及传动装置400。所述制冰盘200用于制冰，所述制冰盘200在制冰位置和脱冰位置之间可转动地设于所述框架100内。防溅水挡板300设于所述制冰盘的两个侧壁上方，每个所述防溅水挡板300均为倾斜设置并朝向所述制冰盘200延伸，所述防溅水挡板300通过设于所述防溅水挡板300一侧的挡板转轴310转动连接于所述框架100。所述传动装置400与所述制冰盘200连接，所述传动装置400用于在所述所述制冰盘200由所述制冰位置向所述脱 冰位置转动时，带动两个所述防溅水挡板300分别绕各自的挡板转轴310向远离所述制冰盘200的方向转动。具体地，在开闭冰箱门时，未结冰的水最容易沿制冰盘200长度方向的两个侧壁溅出，因此两个防溅水挡板300分别设于制冰盘200长度方向的两个侧壁上方。
本发明公开的制冰机，通过在制冰盘200的两个侧壁上方设置防溅水挡板300，从而在用户打开或关闭冰箱门时，可防止未结冰的水从制冰盘200内溢出或溅出；并且设置传动装置400，使得防溅水挡板300在制冰盘200向脱冰位置转动时被传动装置400带动而远离制冰盘200，从而不会阻碍制冰盘200的脱冰。
所述传动装置400还用于在所述制冰盘200由所述脱冰位置向所述制冰位置转动时，带动两个所述防溅水挡板300分别绕各自的挡板转轴310向靠近所述制冰盘200的方向转动。
进一步地，所述制冰盘200的一端设有转动连接于所述框架100的制冰盘转轴210。所述传动装置400包括与所述制冰盘转轴210固定连接的制冰盘齿轮410，与所述制冰盘齿轮410啮合的从动齿轮420，以及分别与两个防溢水挡板转轴310固定连接并彼此啮合的挡板齿轮430，其中一个挡板齿轮430与所述从动齿轮420同轴固定连接。当所述制冰盘齿轮410随所述制冰盘200由所述制冰位置向所述脱冰位置转动时，所述从动齿轮420及与所述从动齿轮420同轴连接的挡板齿轮430跟随转动，并带动两个所述防溢水挡板300分别向远离所述制冰盘200的方向转动。
具体地，如图2-3所示，两个挡板齿轮430分别为第一挡板齿轮431 及第二挡板齿轮432，第一挡板齿轮431与从动齿轮420同轴固定连接，第二挡板齿轮432与第一挡板齿轮431相互啮合。制冰盘200由制冰位置向脱冰位置转动时，制冰盘齿轮410跟随制冰盘转轴210而转动，并带动与其啮合的从动齿轮420反向旋转，而因为第一挡板齿轮431与从动齿轮420同轴固定连接，则第一挡板齿轮431与从动齿轮420的运动状态一致，第二挡板齿轮432与第一挡板齿轮431啮合传动，从而第一挡板齿轮431及第二挡板齿轮432分别带动两个挡板转轴310转动，最终带动两个防溅水挡板300分别向远离制冰盘200的方向转动。这样，在制冰盘200转动脱冰的同时，可以带动防溅水挡板远离制冰盘，不会对制冰盘产生干涉。
从而，本发明实施方式中的制冰机，无需设置额外的动力装置(如电机等)，利用制冰盘的转动及传动装置的传动，即可使防溅水挡板远离制冰盘，方便了用户的使用。
优选地，当所述制冰盘齿轮410随所述制冰盘200由所述脱冰位置向所述制冰位置转动时，所述从动齿轮420及与所述从动齿轮420同轴连接的挡板齿430轮跟随转动，并带动两个所述防溢水挡板300分别向靠近所述制冰盘200的方向转动。
同样地，在制冰盘200由脱冰位置向制冰位置转动过程中，制冰盘齿轮410跟随制冰盘转轴210而转动，并带动与其啮合的从动齿轮420反向旋转，第一挡板齿轮431与从动齿轮420运动状态一致，从而啮合带动第二挡板齿轮432转动；最终，带动两个防溅水挡板300分别向靠近制冰盘200的方向转动。这样，在制冰位置，两个防溅水挡板300设 于制冰盘200两个侧壁的上方，且防溅水挡板300的上方倾斜设置并朝向制冰盘200延伸。
优选地，所述从动齿轮420可选择地与所述制冰盘齿轮410啮合或脱离，所述制冰盘200在由所述制冰位置向所述脱冰位置转动的过程中，所述从动齿轮420与所述制冰盘齿轮410由啮合转向脱离，所述防溅水挡板300相应地由朝向远离所述制冰盘200的方向转动转为相对于所述制冰盘200静止。也就是说，在本发明实施方式中，如图3所示，制冰盘齿轮410及从动齿轮420均为仅在齿轮外表面的一部分设有齿，当制冰盘200处于制冰位置时，制冰盘齿轮410与从动齿轮420相互啮合，在制冰盘200向脱冰位置转动一定的角度后，制冰盘齿轮410与从动齿轮420上相互啮合转动至两个齿轮外表面均没有齿，由此二者从啮合变为脱离，此时制冰盘继续向脱冰位置转动而从动齿轮不再随之转动，进而两个防溅水挡板300也不再转动。
进一步地，所述制冰盘200在由所述脱冰位置向所述制冰位置转动的过程中，所述从动齿轮420与所述制冰盘齿轮410由脱离转向啮合，所述防溅水挡板300相应地由相对于所述制冰盘200静止转为朝向靠近所述制冰盘200的方向转动。具体地，在本发明实施方式中，当制冰盘200处于脱冰位置时，制冰盘齿轮410与从动齿轮420为脱离状态，在制冰盘200向制冰位置转动一定的角度后，制冰盘齿轮410跟随转动至与从动齿轮420上的齿能够相互啮合，此时制冰盘200继续向制冰位置转动，制冰盘齿轮410带动从动齿轮420啮合传动，与从动齿轮420同轴连接的第一挡板齿轮431跟随转动，并带动两个所述防溅水挡板分别 向靠近制冰盘的方向转动。这样，防溅水挡板并不是全程跟随制冰盘转动，因此转动角度无需太大，不会与制冰盘后方的框架产生干涉；另外，在制冰盘由脱冰位置转向制冰位置时，也不会出现防溅水挡板转动而对制冰盘的转动路径产生干涉的情况。
进一步地，所述制冰机还包括驱动所述制冰盘200在制冰位置及脱冰位置之间转动的电机220，所述制冰盘200远离所述制冰盘转轴210的一端与所述电机220的输出轴固定连接。
在本发明实施方式中，所述制冰盘200为扭转制冰盘，也就是说，在脱冰过程中，制冰盘200转动到一个预设位置时，与电机220的输出轴固定连接的一端继续转动，而与制冰盘转轴210固定连接的另一端则被限制转动，进而使制冰盘200发送扭转形变以脱冰。在完成脱冰后，电机220反向驱动制冰盘200转动并回到制冰位置。一般来说，在脱冰过程中，制冰盘200与电机220的输出轴固定连接的一端最大会扭转180度，而与制冰盘转轴210固定连接的另一端最大会扭转120度。同时，在脱冰过程中，在制冰盘由0度扭转至60度时，防溅水挡板300会随制冰盘200的转动而朝向远离制冰盘200的方向转动，在制冰盘200由60度扭转至120度时，防溅水挡板300静止不动。当然，在本发明实施方式中，180度，120度，60度仅为示例，在另外的实施方式中可以采用其他角度。
在本发明实施方式中，如图2所示，所述制冰盘200上与所述制冰盘转轴210垂直的两个侧壁分别向上凸出设有第一导向端板230及第二导向端板240，所述第一导向端板230的内侧面及第二导向端板240的 内侧面分别与两个所述防溅水挡板300的端部接触。与制冰盘转轴210垂直的两个侧壁即为制冰盘200宽度方向上的两个侧壁，在其上设置第一导向端部230及第二导向端板240，并使得两个导向端板的内侧面与防溅水挡板300接触，可将围绕制冰盘200的四壁上方均遮挡起来，进一步提高制冰盘200的防溅水效果。
进一步地，如图4所示，所述防溅水挡板300包括与所述防溅水转轴310固定连接的搭接部320及由所述搭接部320延伸出来的遮挡部330，所述遮挡部330倾斜设置并朝向所述制冰盘200延伸。所述制冰盘200位于所述制冰位置时，所述搭接部320搭接于制冰盘200的侧壁的上表面。搭接部320可使防溅水挡板300与制冰盘200的侧壁上表面接触，而当用户开闭冰箱门时，制冰盘200内未结冰的水晃动时，可沿制冰盘200侧壁向上流动，而倾斜设置的遮挡部330可将水遮挡并使其回落入制冰盘200内，从而防溅水挡板300具有更好的防溅水效果。
本发明公开的制冰机，通过在制冰盘的两个侧壁上方设置防溅水挡板，从而在用户打开或关闭冰箱门时，可防止未结冰的水从制冰盘内溢出或溅出；并且设置传动装置，使得防溅水挡板在制冰盘向脱冰位置转动时被传动装置带动而远离制冰盘，从而不会阻碍制冰盘的脱冰。无需设置额外的动力装置(如电机等)，利用制冰盘的转动及传动装置的传动，即可使防溅水挡板远离制冰盘，方便了用户的使用。制冰盘宽度方向的两侧壁上方设置第一导向端部及第二导向端板，并使得两个导向端板的内侧面与防溅水挡板接触，可将围绕制冰盘的四壁上方均遮挡起来，进一步提高制冰盘200的防溅水效果。
