碎冰装置及冰箱 技术领域
本申请涉及家电的技术领域，具体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。该冰箱的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，以便人们取用。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，人们取用到的是被剪碎的冰块；而冰块模式下，人们取用到的是完整的冰块。
在现有技术中，一般采用在桶状容器内设置碎冰刀组件的方式来实现碎冰模式和冰块模式。碎冰刀组件包括定冰刀和动冰刀，定冰刀的一端活动穿设在碎冰刀组件的转轴上，动冰刀的一端固定穿设在碎冰刀组件的转轴上，以使该转轴带动冰刀转动。当转轴正向转动(也即向定冰刀方向转动)，在动冰刀和定冰刀交错时，碎冰刀组件将冰块剪碎，此为碎冰模式。而当转轴反向旋转时，该碎冰刀组件仅对冰刀附近的冰块起到带动搅拌的作用，并使冰块从桶状容器的出口中滑出，此为冰块模式。
然而，碎冰装置的出冰口为敞开式，在从冰箱中取出冰盒时或者用户开关冰箱门体而产生震动时，出冰口处容易掉落冰块。为了防止冰块发生掉落现象，现有技术在出冰口处增加具有一定高度的斜坡。这种通 过在出冰口增加斜坡的方式，虽然有效地降低了冰块掉落的几率，但是在取整冰时会导致动冰刀与斜坡之间很容易将整冰挤碎，降低了出整冰率。
因此，针对现有技术中防止冰块掉落而导致出整冰率降低的问题，本申请实施例提供一种既能防止冰块掉落又不影响出整冰率的碎冰装置以及相应的冰箱。

具体实施方式
以下将结合附图所示的具体实施方式对本申请进行详细描述。但这些实施方式并不限制本申请，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本申请的保护范围内。
本申请提供的第一优选实施例公开了一种冰箱，冰箱包括箱体和用于打开或关闭箱体的门体，箱体定义了储物间室，其中储物间室的数量和结构形式可根据不同需求进行配置。储物间室通常包括冷藏室和冷冻室。
如图1至图10所示，冰箱还包括碎冰装置100，碎冰装置100设于箱体或门体上。碎冰装置100包括壳体组件10、安装于壳体组件10的驱动机构30以及碎冰机构50，其中壳体组件10包括外壳11以及支撑于外壳11内的冰桶12，驱动机构30用于带动冰桶12旋转，驱动结构30的至少一部分安装于外壳内。碎冰机构50设置在冰桶12内，用于将制冰机制得的冰块打碎。其中，壳体组件10还包括设置于冰桶12底部的排冰基板13，排冰基板13相对于外壳11固定设置，优选的，排冰基板13与外壳11可以是一体设置，如采用注塑一体成型，排冰基板13上设有与冰桶12连通的排冰口131，排冰口131可以是排冰基板13上大 致扇形的开口，扇形开口的圆心角大致小于180度，优选的在120度到170度之间，经制冰机制得的冰块在冰桶12内被碎冰机构50打碎后从排冰口131排出。
本实施例中优选的，驱动机构30包括马达(图未示)以及由马达带动的圆柱齿轮31，冰桶12的外周设有外齿121，圆柱齿轮31与外齿121啮合以带动冰桶12旋转。进一步的，马达和圆柱齿轮31之间设有齿轮组件，齿轮组件包括连接马达的第一锥齿轮32以及与第一锥齿轮32啮合的第二锥齿轮33，圆柱齿轮31与第二锥齿轮33同轴并相对固定设置，也就是说，马达带动第一锥齿轮32旋转，圆柱齿轮31与第二锥齿轮33同步旋转，从而实现将扭矩从马达传递到冰桶12。通过设置两个锥齿轮以及圆柱齿轮31，可以合理的设计驱动机构的整体尺寸，使得马达与齿轮组件的配合更加紧凑，从而碎冰装置整体的体积更加小型化。当然，驱动机构也可以是其它传动结构，如带传动机构、链传动机构、涡轮蜗杆等，齿轮机构也不限于锥齿轮，也可以是直齿轮、斜齿轮、人字齿轮、曲线齿轮等等。
外壳11包括容纳冰桶12的第一部分11a以及安装驱动机构30的第二部分11b，其中第一部分11a构造为与冰桶12外围匹配，即第一部分11a也设置为筒状，冰桶12在筒状的第一部分11a内旋转。为了方便冰桶12的动力传递以及碎冰装置的整体密封性，在第一部分11a上设有开口111，圆柱齿轮31与外齿121的啮合部位于开口111处，如此可以使得开口111最小化，满足圆柱齿轮31与外齿121的稳定啮合即可。壳体组件10还包括底板14，第二部分11b的底部敞开，底板14盖设于第二 部分11b的底部以将圆柱齿轮31密封在第二部分11b和底板14之间，排冰基板13的底部设有卡槽133，底板14上设置于卡槽133形状配合的凸块143，凸块143陷入卡槽133内，优选的将凸块143和卡槽133均设置为鱼形，使得碎冰装置整体的密封性更好。
另外，第一部分11a沿冰桶12轴向间隔设有第一台阶部113和第二台阶部114，冰桶12和第一部分11a之间设有垫环(图中未示出)。垫环的一端具有翻边，翻边抵接于第一台阶部113，垫环的另一端抵接于第二台阶部114，通过设置垫环使得冰桶12的旋转更加稳定，减小冰桶12和外壳11之间的转动磨损。
参照图3所示，为外壳11的制造容易以及驱动机构30的组装方便，壳体组件10还包括连接于外壳11的后盖15，后盖15的外侧连接马达，第一锥齿轮32和第二锥齿轮33支撑在后盖15和外壳11之间。配合参照图4所示，因冰桶12与排冰基板13之间有相对旋转，基于冰桶12与圆柱齿轮31啮合部的开口111以及冰桶12与外壳11之间的间隙存在，为防止冰桶12内的碎冰从开口111或间隙处进入驱动机构30，可以在排冰基板13与第一部分11a之间设置沿冰桶12周向延伸的凹槽136，凹槽136与排冰口131连通，冰桶12的下边缘伸入凹槽136。这样碎冰需要穿过凹槽136才能进入到另一侧的驱动机构30，碎冰会先在凹槽136内堆积，冰桶12转动时，会将碎冰带走，并从出冰口131掉落，这样的设计可以有效地解决碎冰堆积问题。排冰基板13的底部与凹槽136对应的位置形成凸部137，底板14上设有凹部147，凸部137卡入凹部147内以方便底板的装配，并且连接底板的卡槽133与凸部137邻接，由此 可以形成迷宫式密封结构，防止齿轮之间的润滑油或者杂质、碎冰等从壳体组件10漏出。
参照图8，碎冰机构50包括相对于外壳11固定的冰刀轴51以及间隔设置于冰刀轴51上的若干个动冰刀52和若干个定冰刀53，其中冰刀轴51固定在排冰基板13上。冰刀轴51包括轴芯515、轴套511和端部螺母513，轴芯515位于轴套511内部空间。轴芯515的底端设有螺纹，该螺纹与端部螺母513相互匹配。与现有技术不同的是，动冰刀52相对于冰桶12固定，而定冰刀53相对于冰刀轴51固定，这样，动冰刀52由冰桶12带动旋转，而定冰刀53则相对外壳11固定。通过动冰刀52相对于定冰刀53的旋转而将冰桶12内的冰块打碎。另外，为了防止冰块粘结在一起，可以在冰刀轴51远离排冰口131的一端安装搅冰杆54，搅冰杆54可以朝向冰刀轴51的另一端延伸并且与动冰刀52固定，随着动冰刀52一起旋转的同时实现对冰块的搅动。当然，动冰刀52的旋转可以是动冰刀52直接固定于冰桶12的内壁上，也可以是动冰刀52与搅冰杆54相对固定而搅冰杆54固定于冰桶12的内壁上，这里的固定可以是相对于冰桶12周向的固定，轴向可以设置为固定或者相对于冰桶12可以调节轴向的距离。
本实施例中优选的，冰桶12的内壁设有沿着轴向延伸的第一限位槽123，其中搅冰杆54的一端卡设于第一限位槽123内，动冰刀52周向固定于搅冰杆54。动冰刀52包括两个呈一字型的刀片，并且动冰刀52设置两个，同样的定冰刀53也设置两个，动冰刀52与定冰刀53相邻设置，搅冰杆54对应动冰刀52的刀片的数量也设置两个，搅冰杆54的一端设 有沿着轴向延伸的第二限位槽543，两个动冰刀52对应的两个刀片上分别设有凸起523，两个凸起523均卡设于第二限位槽543，实现动冰刀52相对于搅冰杆54的周向固定。
继续参照图4所示，排冰基板13的排冰口131为敞开式。用户在开关冰箱门时产生的震动或者取出冰盒时，使得碎冰块容易从排冰口131掉落。现有技术虽然通过在排冰口131处增加斜坡以防止冰块掉落，但是斜坡在高度方向的延伸会导致动冰刀52至排冰口131的空间减小，导致动冰刀52与斜坡之间的整冰容易被冰挤碎，从而使得碎冰装置100的出整冰率下降。
参照图7至图10所示，本申请实施例在碎冰装置100中增加止挡组件，达到既能防止冰块掉落问题又不影响出整冰率的效果。在该实施例中，止挡组件包括用于止挡冰块的止挡件73、用于为止挡件73提供复位的弹性件72，用于固定止挡件73及弹性件72的固定件71。在本实施方式中，由于弹性件72主要用于为止挡件73复位提供回复力，因此，弹性件72也可被称为回复件。
止挡件73包括止挡部732和固定部731。止挡部732为沿垂直方向具有预定高度及沿水平方向具有预定长度的板状结构，以其自身的结构形成一个止挡面，从而阻挡冰块的掉落。固定部731大体呈圆柱状，包括第一通孔731b和台阶面731a。台阶面731a作为用于固定弹性件72的第一固定端面。第一通孔731b用于与冰刀轴51匹配，在本实施方式中，冰刀轴51的轴芯515穿过第一通孔731b。止挡件73还包括加强肋735，加强肋735位于止挡部732和固定部731之间，用于加强止挡部 732和固定部731之间的连接。止挡部732为板状，固定部731位圆柱状，因此，止挡部732与固定部731之间的原始连接端面为线连接。当冰块的动量较大时，线连接的止挡部732容易发生断裂或脱落，导致止挡失效。加强肋735通过在止挡部732和固定部731之间多架设一层连接，有效地提高了两者之间的连接强度，以及提高止挡件73抗冰块的冲击能力。加强肋735为类似三角形的板面结构，进一步地提高连接面积及连接强度。
本实施方式中，弹性件72具体为扭簧。固定件71的外形大体呈圆柱状，包括用于固定弹性件72的第二固定端面和用于与冰刀轴匹配的第二通孔。
本实施方式中，止挡组件与动冰刀52及定冰刀53同轴地安装于在冰刀轴51上。止挡组件位于相邻的动冰刀52与定冰刀53之间。在安装时，将止挡组件中的固定件71、弹性件72和止挡件73依次套设于轴芯515上。弹性件72(即扭簧)位于第一固定端面和第二固定端面所限定的空间内。碎冰装置100可包括多个止挡组件，从而形成多道止挡。在竖直方向上，多个止挡组件的止挡件73中的止挡部732处于同一个平面。根据力的作用原理，在安装止挡件73时，止挡件73上设有加强肋735的一面需位于排冰口131的一侧。
初始状态下，扭簧处于自由状态；当止挡件73在受到外力而发生旋转后，扭簧受到扭力而转变成工作状态并存储回复力。当止挡件73的旋转扭力变小或消失，扭簧的回复力推动止挡件73产生逆向旋转并恢复初始状态。
在取整冰时，动冰刀52会推动冰块带动止挡件73在水平面上朝排冰口131的方向旋转，当冰块到达排冰口131时，整冰掉落；取整冰结束后，在弹性件72的回复力作用下，止挡件73恢复至初始位置。在取出冰盒时，止挡件73不运动且不受动冰刀52运动的影响，止挡件73位于初始位置，由于止挡件73的止挡作用，可以有效地防止碎冰从排冰口131掉落。
在该实施例中，定义取整冰状态为第二状态，除取整冰状态的其它状态为第一状态。第一状态包括从冰箱中取出冰盒的状态或用户在开关冰箱门时产生的震动状态等。当碎冰装置100处于第一状态时，止挡组件处于初始状态且在排冰口131形成用于阻碍冰块掉落的止挡面；当碎冰装置100处于第二状态时，在外力的作用下(即动冰刀52推动冰块对止挡件73施加的外力)，止挡组件发生位置变动以解除所述止挡面，在外力(即动冰刀52推动冰块对止挡件73施加的外力)消失后，止挡组件回复所述初始状态。止挡组件不仅能够有效地防止碎冰的掉落又能够不影响出整冰率，还具有自动回复初始状态的功能。
图11到图12所示为本申请的另一优选实施方式。本实施方式中，止挡组件安装于排冰基板13临近排冰口131的位置，具体安装在排冰基板13的末端端面上。止挡组件包括用于止挡冰块的止挡件73、用于为止挡件73提供复位的弹性件72；排冰基板13的末端端面上设有用于固定止挡件73及弹性件72的卡扣部132。止挡件73在排冰基板13与排冰口131的交界处形成预设高度的止挡面，由止挡面阻挡冰块掉落的通道。在本实施方式中，由于弹性件72主要用于为止挡件73复位提供回 复力，因此，弹性件72也可被称为回复件。
止挡件73包括止挡部732和固定部731。止挡部732为沿垂直方向具有预定高度及沿水平方向具有预定长度的板状结构，以其自身的结构形成一个止挡面，从而阻挡冰块的掉落。止挡部沿水平方向的长度约等于或略小于排冰基板13的半径。固定部731为圆柱体，也可称为枢转轴。相应地，卡扣部132为具有可容纳所述枢转轴的通孔的卡扣结构(即轴孔结构)。优选地，排冰基板13的末端端面上设有多个卡扣部132且各个卡扣部132间隔预设距离，有助于止挡件73的旋转平衡。固定部731与止挡部732相互连接或者一体化制造。弹性件72具体为扭簧，扭簧套设在所述固定部731上且位于远离外壳11方向的一端，即位于固定部731邻近冰刀轴51的一端。扭簧的一端被冰刀轴51所抵挡，扭簧的另一端被固定部731与止挡部732的连接处所抵挡。在安装时，将固定部731卡接至卡扣部132中，将扭簧套设在固定部731位于邻近冰刀轴51的一端。
初始状态下，扭簧处于自由状态；当止挡件73发生翻转后，扭簧受到扭力而转变成工作状态并存储回复力。当止挡件73的翻转扭力变小或消失，扭簧的回复力推动止挡件73产生逆向翻转并恢复初始状态。
在取整冰时，动冰刀52会推动冰块带动止挡件73在竖直面上朝排冰口131的下方方向旋转，当冰块到达排冰口131时，整冰掉落；取整冰结束后，在弹性件72的回复力作用下，止挡件73恢复至初始位置。在取出冰盒时，止挡件73不运动且不受动冰刀52运动的影响，止挡件73位于初始位置，由于止挡件73的止挡作用，可以有效地防止碎冰从 排冰口131掉落。
在该实施例中，定义取整冰状态为第二状态，除取整冰状态的其它状态为第一状态。第一状态包括从冰箱中取出冰盒的状态或用户在开关冰箱门时产生的震动状态等。当碎冰装置100处于第一状态时，止挡组件处于初始状态且在排冰口131形成用于阻碍冰块掉落的止挡面；当碎冰装置100处于第二状态时，在外力的作用下(即动冰刀52推动冰块对止挡件73施加的外力)，止挡组件发生位置变动以解除所述止挡面，在外力(即动冰刀52推动冰块对止挡件73施加的外力)消失后，止挡组件能够回复所述初始状态。止挡组件不仅能够有效地防止碎冰的掉落又能够不影响取整冰率，还具有自动回复初始状态的功能。
在该实施例中，驱动机构30的驱动对象也可以替换为冰刀轴51，即驱动机构30带动冰刀轴51旋转，而冰桶12相对外壳11固定。由于驱动机构30带动冰刀轴51旋转而冰桶12相对外壳11固定的碎冰方式是现有技术(CN105509391A)，此处不再赘述。
图13到图14所示为本申请的再一优选实施方式，本实施方式中，止挡组件只包括止挡件73，至少部分止挡件73具有弹性属性。止挡件73安装于排冰基板13临近排冰口131的位置，具体安装在排冰基板13的末端端面上。
止挡件73包括止挡部732和固定部731。止挡部732具有弹性属性，当止挡部732在受到外力作用时，其自身能够发生弹性弯曲；在外力作用消失后，由其自身的弹性属性能够恢复初始状态。在本实施方式中，止挡部732的制作材料具体为硅橡胶。在其他实施方式中，止挡部732 的制作材料也可以采用其他类型的具有弹性性质的材料。
止挡部732为沿垂直方向具有预定高度及沿水平方向具有预定长度的曲面结构，且曲面结构的凹陷面朝向储冰区域。止挡部732以其自身的结构形成一个止挡曲面，从而阻挡冰块的掉落。止挡部732包括远离排冰基板13的末端732a和与排冰基板13的基板表面135相交的交接端732b。止挡部732的截面厚度沿交接端732b至末端732a的方向逐渐减小，从而有效地平衡阻挡碎冰的阻挡力及取整冰时所需的弹性力。止挡部732的高度低于最下侧动冰刀52的垂直高度。
固定部731紧贴排冰基板13的侧壁部134，从而将止挡件73固定在排冰基板13的末端端面上。固定部731可以与止挡部732一体成型。为了组装简便，止挡件73与外壳11二次注塑成型。
在取整冰时，动冰刀52会推动冰块带动止挡件73发生弹性形变，当冰块到达排冰口131时，整冰掉落；取整冰结束后，止挡件73在自身弹性回复力作用下，恢复至初始位置。在取冰盒时，止挡件73不受外力且不发生形变，由于止挡件73的止挡作用，可以有效地防止碎冰从排冰口131掉落。
在该实施例中，定义取整冰状态为第二状态，除取整冰状态的其它状态为第一状态。第一状态包括从冰箱中取出冰盒的状态或用户在开关冰箱门时产生的震动状态等。当碎冰装置100处于第一状态时，止挡件73处于初始状态且在排冰口131形成用于阻碍冰块掉落的止挡面；当碎冰装置100处于第二状态时，在外力的作用下(即动冰刀52推动冰块对止挡件73施加的外力)，止挡件73发生形状变化以解除所述止挡面， 在外力(即动冰刀52推动冰块对止挡件73施加的外力)消失后，止挡件73在自身弹性作用下回复初始状态。止挡件73不仅能够有效地防止碎冰的掉落，又能够不影响出整冰率，通过自身的弹性属性还具有自动回复初始状态的功能。
在该实施例中，驱动机构30的驱动对象也可以替换为冰刀轴51，即驱动机构30带动冰刀轴51旋转，而冰桶12相对外壳11固定。由于驱动机构30带动冰刀轴51旋转而冰桶12相对外壳11固定的碎冰方式是现有技术，此处不再赘述。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
尽管上面已经示出和描述了本申请的实施例，可以理解的是，上述实施例是示例性的，不能理解为对本申请的限制，本领域的普通技术人员在本申请的范围内可以对上述实施例进行变化、修改、替换和变型。
