Description

冰箱 技术领域
本发明涉及包括制冰装置的冰箱。
背景技术
包括制冰装置的冰箱正广泛普及。在包括制冰装置的冰箱中，在很多情况下包括供水箱和将供水箱内的水吸上来以供给到制冰盘的水泵。在这样的冰箱中，提出了一种在将水泵和供水箱连接和分离时具有更好的操作性的冰箱(例如，参考专利文献1-特开2021-25712号公报)。
然而，在专利文献1中记载的冰箱中，供水箱和水泵位于冰箱主体的高度方向上的中央部分，导致最适合收纳的区域被供水箱和水泵占用了，无法有效地利用收纳区域。
发明内容
利用本发明的目的是提供一种冰箱，其在包括制冰装置的同时也能有效地利用收纳区域。
本发明所涉及的冰箱，其是具有主体和以能开关的状态安装在所述主体上的旋转门的冰箱，所述冰箱包括：分配器接收部，其配设在所述旋转门上，具有分配器接收部和供液侧流路，所述分配器接收部供被配设成液体出口朝下的液体容器的颈部插入，并且所述供液侧流路安装到所述分配器接收部，与所述液体容器的液体出口连通；以及制冰部，其配设在所述主体上，具有制冰盘和具有位于所述制冰盘上方的出液口的制冰侧流路；所述供液侧流路与所述制冰侧流路至少在所述旋转门关闭的状态下连通，所述液体容器内的液体在重力作用下流经所述供液侧流路和所述制冰侧流路而供给至所述制冰盘。
在本发明中，液体容器不是配设在冰箱的主体上而是配设在旋转门上，并且液体在重力作用下流动并供给至制冰盘，因此不存在供液泵。由此，冰箱主体的制冰盘周围的适于收纳的区域不会被液体容器和供液泵所占用。这样就能够提供在包括制冰装置的同时能够有效地利用收纳区域的冰箱。
此外，本发明所涉及的冰箱，所述供液侧流路和所述制冰侧流路由配管构成，其中一个流路的端部区域插入另一流路的端部区域内，并且在插入的状态下，在所述其中一个流路的端部区域的外表面与所述另一流路的端部区前域的内表面之间形成液密状态；在所述旋转门关闭的状态下，所述其中一个流路的端部区域插入所述另一流路的端部区域，并且所述供液侧流路与所述制冰侧流路连通；在所述旋转门打开的状态下，所述其中一个流路的端部区域没有插入所述另一流路的端部区域，并且所述供液侧流路与所述制冰侧流路不连通。
在本发明中，供液侧流路和制冰侧流路由配管构成，并且不存在供液泵，因此可以可靠且容易地从旋转门或冰箱主体卸下配管并清洗或维护配管。此外，使得其中一个流路的端部区域与另一流路的端部区域配合旋转门的开关而 连接/不连接，因此在开关旋转门时，其中一个流路与另一流路之间不会发生干涉，可以实现顺畅的开关。
此外，本发明所涉及的冰箱，所述其中一个流路的端部区域和所述另一流路的端部区域中的至少一个由弹性部件以可移动的状态支撑。
在本发明中，由于其中一个流路的端部区域和另一流路的端部区域中的至少一个由弹性部件以可移动的状态支撑，因此即使是在其中一个流路的端部区域和另一流路的端部区域的位置稍微偏移的情况下，其中一个流路的端部区域也可靠地插入另一流路的端部区域，并且供液侧流路与制冰侧流路能够可靠地连通。
此外，本发明所涉及的冰箱，所述分配器接收部处包括通过致动装置(actuator)而开关的开/关阀；在所述开/关阀打开的状态下，所述液体容器的液体出口与所述供液侧流路连通，在所述开/关阀关闭的状态下，所述液体容器的液体出口与所述供液侧流路之间断开；所述致动装置配设在所述主体处，在所述旋转门关闭的状态下，所述致动装置的驱动面与所述开/关阀的被驱动面处于彼此相对的位置，能开关所述开/关阀，并且在所述旋转门敞开的状态下，所述致动装置的驱动面与所述开/关阀的被驱动面不处于彼此相对的位置，并且所述开/关阀保持关闭的状态。
在本发明中，在旋转门关闭的状态下，通过致动装置来开关开/关阀，能够将指定量的液体容器内的液体供给至制冰盘，而在旋转门打开的状态下，开/关阀总是保持关闭，能够防止液体容器内的液体向外漏出。
此外，本发明所涉及的冰箱，在相对于所述旋转门关闭的位置打开第一角度以上的情况下，所述致动装置的驱动面与所述开/关阀的被驱动面不处于彼此相对的位置，且所述开/关阀保持关闭的状态，并且在相对于所述旋转门关闭的位置打开第二角度以上的情况下，所述第二角度是大于所述第一角度的角度，所述供液侧流路与制冰侧流路不连通。
在当液体容器内的液体正供给至制冰盘时打开旋转门的情况下，在旋转门的旋转角到达第一角度的时候开/关阀变为关闭，于是液体停止从液体容器流出。假如在到达第一角度的时候供液侧流路和制冰侧流路还变为不连通，则积存在供液侧流路内的液体可能会从供液侧流路的液体出口向外流出。然而，在本发明中，由于在到达第一角度后供液侧流路与制冰侧流路仍保持连通状态，因此积存在供液侧流路内的液体流向制冰侧流路侧，并且在到达第二角度的时候，当供液侧流路和制冰侧流路变为不连通时，能够形成供液侧流路内没有液体积存的状态。这样，即使当液体容器内的液体正供给至制冰盘时打开了旋转门，也能够顺畅地打开旋转门而没有水漏到外部。
此外，本发明所涉及的冰箱，在所述分配器接收部处包括用于测量所述颈部被插入的所述液体容器的重量的传感器，根据所述传感器的测定值来制定所述开/关阀打开的时间。
在被配设为液体出口朝下的液体容器内的液体在重力作用下供给至制冰盘的情况下，随着液体从液体容器流出，液体容器内的液体的液面下降且液体出 口处的压力降低，于是液体的流速降低。在本发明中，根据用于测量液体容器的重量的传感器的测定值来制定开/关阀打开的时间，因此能够总是可靠地向制冰盘供给一定量的液体。
根据本发明，能够提供在包括制冰装置的同时也能有效地利用收纳区域的冰箱。

具体实施方式
接下来参考附图来对用于实施本发明的实施例进行说明。接下来说明的冰箱是用于具现化本发明的技术思想的内容，只要没有特定的记载，本发明就不限于接下来的内容。在各图中，存在具有同样功能的部件附有同样符号的情况。为了明确地进行说明，存在夸张地示出各图所示的部件的大小或位置关系等的情况。后文的记载和附图中的上下方向示出了三维空间中的竖直方向。
<一个实施例所涉及的冰箱)
图1A是从前侧看本发明的一个实施例所涉及的冰箱2的立体图。图1B是图1A中的箭头A所示的区域的放大示出的立体图。图2A是从后侧看本发明的一个实施例所涉及的冰箱2的立体图，是去除了外壳的侧面以便能够看到内部的图。图2B是图2A中的箭头B所示的区域的放大示出的立体图。图3是示意性地示出包括在图1A所示的冰箱中的本发明的一个实施例所涉及的制冰装置8的结构的图。
本实施例所涉及的冰箱2包括主体4，以及以能开关的状态安装在主体4的前侧的旋转门6A、6B。旋转门6A、6B左右排列在主体4的前表面上，都是向外侧打开的左右对开门。旋转门6A、6B的下侧还包括旋转门或拉出式收纳室。省略了关于冰箱2的总体结构的进一步详细的说明。
<制冰装置>
本实施例所涉及的冰箱2包括制冰装置8。如下文详细示出的那样，该制冰装置8由供液部10和制冰部20构成。
<制冰部>
如图3示意性地示出的，构成本实施例所涉及的制冰装置8的制冰盘22配设在冰箱2的主体4的高度方向上的中央区域。若进一步详细描述的话，制冰盘22配设在比从前侧看的左侧的旋转门6A的下端稍微更下侧。制冰盘22的上表面开口，并利用间隔壁而形成有多个制冰区域。作为制冰盘22，可以使用具有任意大小的任意数量的制冰区域的制冰盘。
冰箱2的主体4上配设有用于向制冰盘22供给液体的制冰侧流路24，作为制冰侧流路24的液体出口的出液口24B配设在制冰盘22上方。作为与制冰侧 流路24的出液口24B相反侧的端部的液体入口24A配设在关闭状态的旋转门6A的旋转轴侧的端部附近(参考图1B)。
这样，本实施例所涉及的制冰装置8的制冰部20配设在冰箱2的主体4侧，具有制冰盘22和具有位于制冰盘22上方的出液口24B的制冰侧流路24。
<供液部>
另一方面，在本实施例所涉及的制冰装置8中，用于贮藏供给至制冰盘22的液体的液体容器P不在冰箱2的主体4中，而是配设在旋转门6A上。可以使用例如装有饮用水的市售塑料瓶作为液体容器P。但是不限于此，可以使用树脂制、玻璃制或金属制的瓶状的任何液体容器。
分配器接收部12配设在旋转门6A的收纳凹部处。在本实施例中，液体容器P以倒置的方式安装到分配器接收部12，使得液体出口朝下。在液体出口朝下的状态下，瓶状的液体容器P的颈部被插入并保持在分配器接收部12。若进一步详细描述的话，分配器接收部12的插入孔的内表面与倒置的液体容器P的颈部的外表面接触，从而保持液体容器P。
插入分配器接收部12的插入孔的深度取决于液体容器P的颈部的形状、大小而不同，因此液体容器P的液体出口的高度位置或多或少也是不同的。然而，本实施例所涉及的分配器接收部12的插入孔具有适应于任意形状、大小的颈部的足够的深度(高度尺寸)。进一步地，还可以包括用于支撑液体容器P的容器本体部分的支撑装置。
供液侧流路14安装在分配器接收部12的插入孔的下侧。这样，使得液体容器P的液体出口与供液侧流路14连通。如后所述，液体容器P的液体出口与供液侧流路14之间安装有用于进行流路的开关的开/关阀32。
供液侧流路14从分配器接收部12延伸到旋转门6A的旋转轴侧的端部。然后，在旋转门6A关闭的状态下，供液侧流路14的液体出口14A与上述制冰侧流路24的液体入口24A相连，使得供液侧流路14与制冰侧流路24连通。这样，液体容器P内的液体在重力作用下从液体出口流出，在供液侧流路14内流向出口14A侧，进一步从入口24A流入制冰侧流路24内，并从出液口24B供给至制冰盘22。液体容器P的液体出口配设在比制冰侧流路24的出液口24B更高的位置处。
这样，本实施例所涉及的制冰装置8的供液部10配设在旋转门6A侧，并且具有供被配设成液体出口朝下的液体容器P的颈部插入的分配器接收部12、以及安装到分配器接收部12的与液体容器P的液体出口连通的供液侧流路14。
如上所述，本实施例所涉及的冰箱2具有主体4和以能开关的状态安装到主体4的旋转门6A，并且包括配设在旋转门6A上的供液部10和配设在主体4上的制冰部20，供液部10具有供被配设成液体出口朝下的液体容器P的颈部插入的分配器接收部12和安装到分配器接收部12的与液体容器P的液体出口连通的供液侧流路14，并且制冰部20具有制冰盘22和具有位于制冰盘22上方的出液口24B的制冰侧流路24，至少在旋转门6A关闭的状态下，供液侧流路 14与制冰侧流路24连通，液体容器P内的液体在重力作用下流经供液侧流路14和制冰侧流路24而供给至制冰盘22。
这样，在本实施例所涉及的冰箱2中，液体容器P没有配设在冰箱2的主体4上而是配设在旋转门6A上，并且液体在重力作用下流动而供给至制冰盘22，因此不存在供液泵。由此，冰箱2的主体4的制冰盘22周围的适于收纳的区域就不会被液体容器和供液泵所占用。这样就能够提供在包括制冰装置8的同时也能有效地利用收纳区域的冰箱2。
<配管的装卸结构>
图4是示出在拆卸下构成本发明的一个实施例所涉及的制冰装置8的制冰侧流路24的配管时的立体图。在本实施例所涉及的制冰装置8中，供液侧流路14和制冰侧流路24由配管构成。例如，如图4所示，制冰侧流路24配设在主体4的内胆与外壳之间的区域，被能拆卸的盖子4A所覆盖。能够容易地取下盖子4A并拆卸下构成制冰侧流路24的配管。这样，能够容易且可靠地进行制冰侧流路24的配管的清洗和维护。关于供液侧流路14也是一样，可以容易且可靠地将配管从旋转门6A卸下并进行配管的清洗和维护。
<供液侧流路和制冰侧流路的连接机构的第一示例>
图5A、图5B是示出供液侧流路14和制冰侧流路24的连接机构的第一示例的平面图，图5A是示出旋转门6A打开并且供液侧流路14与制冰侧流路24处于不连通的状态的图，图5B是示出旋转门6A关闭并且供液侧流路14与制冰侧流路24处于连通的状态的图。图5C是示出供液侧流路14和制冰侧流路24的连接机构的第一示例的连接凸部16侧的立体图。在图5C中，示出了去除图5A、5B所示的壳体16A的状态。
在该连接机构的第一示例中，供液侧流路14的出口侧的端部区域设有连接凸部16，并且连接凸部16的端部开口形成供液侧流路14的液体出口14A。另一方面，制冰侧流路24的入口侧的端部区域设有连接凹部26，并且连接凹部26的端部开口形成制冰侧流路24的液体入口24A。
如图5A所示，在旋转门6A打开的状态下，供液侧流路14的端部区域的连接凸部16没有插入制冰侧流路24的端部区域的连接凹部26，并且供液侧流路14与制冰侧流路24处于不连通状态。另一方面，如图5B所示，在旋转门6A关闭的状态下，供液侧流路14的端部区域的连接凸部16插入制冰侧流路24的端部区域的连接凹部26，并且供液侧流路14与制冰侧流路24处于连通的状态。在供液侧流路14的连接凸部16插入制冰侧流路24的连接凹部26的状态下，连接凸部16的外表面与连接凹部26的内表面之间成为液密状态。具体地，通过设在连接凸部16上的密封部件(例如环形密封圈)来形成液密状态。
不限于如上所述的供液侧流路14设有连接凸部16并且制冰侧流路24设有连接凹部26的情况，与此相反的供液侧流路14设有连接凹部而制冰侧流路24设有连接凸部的情况也是可以的。此外，可以采用其他任意构造的连接机构，只要是如下构造即可：在旋转门6A关闭的状态下供液侧流路14和制冰侧流路 24的端部区域中的一个以液密的状态插入另一个，而在旋转门6A打开的状态下该插入状态解除。
在如上所述的供液侧流路14和制冰侧流路24的连接机构的第一示例中，供液侧流路14和制冰侧流路24由配管构成，其中一个流路14(24)的端部区域插入另一流路24(14)的端部区域内，并且使得在插入状态下其中一个流路14(24)的端部区域的外表面与另一流路24(14)的端部区域的内表面之间形成液密状态，在旋转门6A关闭的状态下，其中一个流路14(24)的端部区域插入另一流路24(14)的端部区域并且供液侧流路14与制冰侧流路24连通，而在旋转门6A打开的状态下，其中一个流路14(24)的端部区域没有插入另一流路24(14)的端部区域并且供液侧流路14与制冰侧流路24不连通。
在连接机构的第一示例中，其中一个流路14(24)的端部区域与另一流路24(14)的端部区域配合旋转门6A的开闭而连接/不连接，因此在开闭旋转门6A时，其中一个流路14(24)和另一流路24(14)之间不会发生干涉，可以实现顺畅的开闭。
在图5C中，示出了去除壳体16B的状态，但是在连接机构的第一示例中，连接凸部16经由弹簧16B安装在壳体16A的内壁上。这样，连接凸部16以在平面视图中可上下左右移动(参考图5C的虚线箭头)的状态安装到壳体16A。也就是说，连接凸部16通过弹簧16B而以可移动的状态支撑。由此，即使供液侧流路14的出口14A的位置与制冰侧流路24的入口24A的位置稍微偏移，连接凸部16也能可靠地插入连接凹部26，并且供液侧流路14和制冰侧流路24能够可靠地连接。
在上述记载中，连接凸部16通过弹簧16B以可移动的状态支撑，但是不限于此。相反，连接凹部26通过弹簧以可移动的状态支撑的情况也是可以的。进一步地，连接凸部16和连接凹部26二者都通过弹簧以可移动的状态支撑的情况也是可以的。弹簧16B既可以由金属材料形成也可以由树脂材料形成。此外，作为弹簧16B的代替，也可以用弹性橡胶之类的弹性部件来支撑连接凸部16。
在如上所述的连接机构的第一示例中，其中一个流路14(24)的端部区域和另一流路24(14)的端部区域中的至少一个通过弹性部件16B而以可移动的状态支撑。由此，即使是在其中一个流路14(24)的端部区域和另一流路24(14)的端部区域的位置稍微偏移的情况下，其中一个流路14(24)的端部区域也能可靠地插入另一流路24(14)的端部区域，并且供液侧流路14和制冰侧流路24能够可靠地连通。
<开/关阀的开闭机构>
<开闭机构的第一示例>
图6A是示出安装到分配器接收部12的液体容器P和用于开关液体容器P的液体出口的开/关阀32的开闭机构30的第一示例的侧视图。图6B、图6C是图6A的开闭机构30的放大示意图，图6B是示出开/关阀32处于关闭状态的情 况的图，图6C是示出开/关阀32处于打开状态的情况的图。所有图都示出了旋转门6A处于关闭状态的情况。
本实施例所涉及的制冰装置8的分配器接收部12包括通过致动装置34进行开关的开/关阀32。致动装置34配设在冰箱的2的主体4上。通过开/关阀32和致动装置34构成开闭机构30。开/关阀32包括管口部32A和安装到管口部32A的手柄部32B。管口部32A配设在液体容器P的液体出口与供液侧流路14之间，并且能够使二者在连通状态与断开状态之间切换。
如图6B所示，在手柄部32B位于下侧位置的情况下，管口部32A成为关闭的状态。在这种情况下，液体容器P内的液体不向外流出。另一方面，如图6C所示，在手柄部32B位于上侧位置的情况下，管口部32A成为打开的状态。在这种情况下，液体容器P内的液体向外流出。
在本实施例中，致动装置34配设在冰箱2的主体4侧，在图6A至图6C中，示出了旋转门6A关闭并且致动装置34位于手柄部32B的下侧的情况。作为致动装置34，采用在端部具有头部34A的轴伸缩的气缸。气缸的轴利用内置磁控阀或电动马达等而伸缩。
在旋转门6A关闭的状态下，致动装置34的驱动面34A1与开/关阀32的被驱动面32B1处于彼此相对的位置。如图6B所示，轴缩回(拉入)的状态下，头部34A的驱动面34A1与开/关阀32的手柄部32B的被驱动面32B1处于分开的状态。在该状态下，藉由内置于管口部32A中的弹簧的压力，管口部32A保持关闭的状态。
当轴向外侧伸出时，头部34A的驱动面34A1与开/关阀32的手柄部32B的被驱动面32B1抵接并使手柄部32B向上方移动。然后，如图6C所示，在手柄部32B到达上侧位置的情况下，管口部32A成为打开的状态，此时，液体容器P内的液体向供液侧流路14侧流出。当致动装置34的轴再次缩回(拉入)时，藉由内置于管口部32A中的弹簧的压力，管口部32A再次回到关闭的状态，并且液体容器P的液体出口封闭。
另一方面，在旋转门6A打开的状态下，致动装置34不位于手柄部32B的下侧。由此，致动装置34的驱动面34A1与开/关阀32的被驱动面32B1不处于彼此相对的位置，藉由内置于管口部32A中的弹簧的压力，管口部32A保持关闭的状态。也就是说，在旋转门6A打开的状态下，能够防止液体容器P内的液体向外流出。
<开闭机构的第二示例>
图7是示出开闭机构30的致动装置36的第二示例的立体图。本示例的致动装置36由在驱动轴上安装有小齿轮的电动马达36A和与小齿轮咬合的齿条36B构成。在齿条36B通过电动马达36A的旋转而向上方移动时，管口部32A打开，并且液体容器P内的液体向供液侧流路14侧流出。然后，当电动马达36A逆向旋转使齿条36B向下方移动时，利用内置于管口部32A中的弹簧的压力，管口部32A再次回到关闭的状态，并且液体容器P的液体出口封闭。
如上所述，在本实施例所涉及的制冰装置8中，分配器接收部12处包括通过致动装置34(36)而开关的开/关阀32，并且在开/关阀32打开的状态下，液体容器P的液体出口与供液侧流路14连通，而在开/关阀32关闭的状态下，液体容器P的液体出口与供液侧流路14之间断开，致动装置34(36)配设在主体4上，在旋转门6A关闭的状态下，致动装置34(36)的驱动面(例如34A1)与开/关阀32的被驱动面(例如32B1)处于彼此相对的位置，从而能够开关开/关阀32，而在旋转门6A敞开的状态下，致动装置34(36)的驱动面(例如34A1)与开/关阀32的被驱动面(例如32B1)不处于彼此相对的位置，从而使开/关阀32保持关闭的状态。
这样，在旋转门6A关闭的状态下，能够通过致动装置34(36)来开关开/关阀32以将指定量的液体容器P内的液体供给至制冰盘22，而在旋转门6A打开的状态下，开/关阀32总是保持关闭，并且能够防止液体容器P内的液体向外漏出。
<打开旋转门时的状况>
图8A和图8B是示出旋转门6A从关闭状态打开时，开闭机构的动作状态以及供液侧流路14和制冰侧流路24的连接状态的图，图8A是示出旋转门6A打开仅第一角度θ1时的图，图8B是示出旋转门6A打开仅第二角度θ2时的图。在后文中，以如下情况为例进行说明：在旋转门6A关闭的状态时，打开开/关阀32使液体容器P内的液体经由供液侧流路14和制冰侧流路24供给至制冰盘22期间旋转门6A被打开。这里示出的是使用第一示例的致动装置34的情况。
在旋转门6A被从关闭状态打开时，当旋转角度到达第一角度θ1处时，如图8A所示，致动装置34的驱动面34A1与开/关阀32的被驱动面32B1从彼此相对的位置脱离，开/关阀32利用弹簧的压力由打开变为关闭，从而保持关闭的状态。在继续打开旋转门6A使得旋转角度到达第二角度θ2处时，第二角度θ2是大于第一角度θ1的角度，如图8B所示，供液侧流路14与制冰侧流路24变为不连通。
当在开/关阀32处于打开状态使液体容器P内的液体供给至制冰盘22打开旋转门6A时，在旋转角度到达第一角度θ1的时候液体从液体容器P的流出停止。然而，由于有液体积存在供液侧流路14内，因此假如在旋转角度到达第一角度θ1的时候就使供液侧流路14和制冰侧流路24也变为不连通，那么可能会有积存在供液侧流路14内的液体从液体出口14A向外流出的问题。
然而，在本实施例中，即使旋转门6A的旋转角度到达第一角度θ1也仍保持供液侧流路14与制冰侧流路24连通的状态，因此积存在供液侧流路14内的液体流向制冰侧流路24。此后，当旋转门6A的旋转角度到达第二角度的时候，供液侧流路14与制冰侧流路24变为不连通，但供液侧流路14内基本上没有液体残存，因此能够防止液体从供液侧流路14向外部流出。即使仍有少量液体残存在供液侧流路14中，由于液体容器P的液体出口被封闭，因此液体容器P内的液体头部也不会滴落，能够利用表面张力防止液体向外流出。
这样，即使是在液体容器P内的液体正供给至制冰盘22时打开旋转门6A，水也不会漏到外部，并且能够顺畅地打开旋转门6A。在本实施例中，在当液体容器P内的液体正供给至制冰盘22时打开旋转门6A的情况下，进行致动装置34(36)返回关闭状态的控制处理。这样，即使是在正在打开的旋转门6A被关闭的情况下，也能防止致动装置34(36)与开/关阀32发生干涉。
<连接区域处的变型示例>
图9A、图9B是示出供液侧流路14和制冰侧流路24的连接区域处的变型示例的图，图9A是示出供液侧流路14和制冰侧流路24处于不连通的状态的图，图9B是示出供液侧流路14和制冰侧流路24连通的状态的图。
在该变型示例中，供液侧流路14的出口侧的端部区域设有第一密封部件18，第一密封部件18的端部开口形成供液侧流路14的出口14A。另一方面，制冰侧流路24的入口侧的端部区域设有第二密封部件28，第二密封部件28的端部开口(突起部28A除外)形成制冰侧流路24的入口24A。
第一密封部件18包括用弹簧18B压住的密封座18A。通常，密封座18A因弹簧18B的压力而抵接到第一密封部件18的内侧壁部，并且供液侧流路14变为关闭的状态。第二密封部件28处包括向前端突出的突起部28A。在旋转门6A打开的状态下，供液侧流路14的出口14A因弹簧18B的压力而变为关闭的状态。另一方面，在旋转门6A关闭的状态下，第二密封部件28的突起部28A插入第一密封部件18的开口部并推挤密封座18A，从而在密封座18A与第一密封部件18的内侧壁部之间形成间隙。这样，供液侧流路14的出口14A就变为打开的状态。
在连接区域处的变型示例中，在旋转门6A关闭的状态下，第二密封部件28的突起部28A插入第一密封部件18的开口部使供液侧流路14的出口14A变为打开的状态。由此，在任何时刻都可以将液体容器P内的液体供给至制冰盘22。另一方面，在旋转门6A打开的状态下，供液侧流路14的出口14A变为总是关闭的状态，因此能够防止液体从供液侧流路14向外部流出。
<包括重量传感器的分配器接收部>
图10是示出包括重量传感器40的分配器接收部12的图，重量传感器40用于测量液体容器P的重量。在该分配器接收部12处，在下侧安装有重量传感器40。通过重量传感器40能够在颈部插入液体出口朝下的状态下测量液体容器P的重量。
当被配设成液体出口朝下的液体容器P内的液体在重力作用下从液体出口流出时，随着液体从液体容器P流出，液体容器内的液体水位下降，并且流出的液体的流速降低。然而，在本实施例中，开/关阀32打开的时间被控制根据用于测量液体容器P的重量的传感器40的测定值来确定。这样，总是有一定量的液体能够可靠地供给至制冰盘22。
<能折叠的分配器接收部>
图11是示出能折叠的分配器接收部12的变型示例的立体图。如图11的(a)中的箭头所示，该分配器接收部12能够折叠上侧和下侧的部件。在如夏 季这样的需要制冰的时期，以如图11的(a)中那样的展开状态承接液体容器P，可以将液体容器P内的液体供给至制冰盘22。另一方面，在如冬季这样的不需要制冰的时期，以如图11的(b)中那样的折叠状态，能够增加旋转门6A的收纳区域。通过折叠分配器接收部12，可以将塑料瓶之类的饮料容器以液体出口朝上的通常放置方式收纳在旋转门6A的收纳凹部处。
<供液侧流路和制冰侧流路的连接机构的第二示例>
图12A是示出供液侧流路14和制冰侧流路24的连接机构的第二示例的立体图。图12B、图12C是示出图12A所示的连接功能的平面图，图12B是示出软管被拉入的状态的图，图12C是示出软管被拉出的状态的图。
在该连接机构的第二示例中，制冰侧流路24的入口侧区域由软管62构成，软管62安装到伸缩式连接部60。伸缩式连接部60安装在冰箱2的主体4侧，并且软管62的固定侧的端部与制冰盘22侧的出液口24B连通。软管62的移动侧的端部形成与供液侧流路14相连的入口24A。与上述第一示例的不同之处在于，在第二示例中，供液侧流路14和制冰侧流路24总是处于连通的状态。
伸缩式连接部60是可旋转的，其架设在连接到伸缩式连接部60主体的两个滚轮64A、64B上。滚轮64B通过弹簧66而压向使软管62的移动侧的端部区域拉入伸缩式连接部60内里的方向。
这样，当关闭的旋转门6A被打开时，软管62被从伸缩式连接部60向外侧拉出，并且旋转门6A可以变为打开状态而供液侧流路14和制冰侧流路24仍然相连。另一方面，在打开的旋转门6A被关闭时，软管62因弹簧66的压力而被拉入伸缩式连接部60内里，因此软管62与旋转门6A不会发生干涉，并且旋转门6A可以变为关闭状态。利用如上所述的构造，能够以供液侧流路14和制冰侧流路24就那样保持连通状态的方式顺畅地开闭旋转门6A。
<供液侧流路和制冰侧流路的连接机构的第三示例>
图13A、图13B是示出供液侧流路14和制冰侧流路24的连接机构的第三示例的立体图，图13A是示出旋转门6A打开的状态的图，图6B是示出旋转门6A关闭的状态的图。在每幅图中，(a)示出了冰箱整体，并且(b)是放大示出(a)的图中用圆圈围住的区域的图。
在该连接机构的第三示例中，供液侧流路14和制冰侧流路24用配设在旋转门6A的旋转轴位置处的旋转接头70来连接。旋转接头70安装到冰箱2的主体4上。在该第三示例中，供液侧流路14和制冰侧流路24也是总是保持连通的状态。利用这样的旋转接头70，能够以供液侧流路14和制冰侧流路24就那样保持连通状态的方式顺畅地开闭旋转门6A。
尽管说明了本发明的实施例和实施方式，但是公开内容在构成的细节方面有所变化也是可以的，也可以实现实施例、实施方式中的要素的组合或顺序的变化等，而不脱离所请求的本发明的范围和思想。
