Description

给液装置和包括给液装置的冰箱 技术领域
本发明涉及制冷电器领域，尤其是向制冰皿供给液体的给液装置和包括该给液装置的冰箱。
背景技术
已知包括在冰箱中的向制冰皿供给液体的给液装置。在这样的给液装置中，在大多数情况下是通过给液泵向制冰皿供给储存在储液区域中的液体。在这种情况下，为了抑制在连接储液区域与制冰皿的流路中的霉或杂菌之类的繁殖，优选地用使储液箱和制冰皿与外部气体隔绝的封闭流路来进行连接。然而，在液体残留在封闭流路中的情况下，会因虹吸现象而发生液体逆流的问题。
为了应对该问题，提出了这样的给液装置：在具有连接储液箱与制冰皿的封闭流路的给液装置中，采用以齿轮泵为代表的能正向逆向转动的容积式泵作为给液泵(例如，参考专利文献1-特开平7-260306号)。在专利文献1中记载的制冰装置中，使作为容积式泵的给液泵逆向转动，将残留在封闭流路中的液体回收到给液箱中，防止由虹吸现象引起的逆流。
然而，出于给液泵的制造成本和可维护性之类的考虑，比起容积式泵，使用广泛使用的非容积式泵是更加优选的。然而，在连接储液箱与制冰皿的封闭流路中采用非容积式泵的情况下，由于非容积式泵不能逆向转动，因此无法除去残留在流路中的液体。
如果为了防止虹吸现象的发生而在形成流路的配管上设置导入外部气体的开口，则可能会因开口而在流路中发生霉和杂菌之类的繁殖。
发明内容
本发明的目的是在于提供即使使用不能逆向转动的泵作为给液泵也能以保持清洁的状态向制冰皿供给储存在储液区域中的液体的给液装置和包括该给液装置的冰箱。

配设在所述储液箱体内的在所述储液区域上方的辅助储液区域；
给液泵，其是非容积式泵，用于向所述辅助储液区域供给储存在所述储液区域中的液体；以及
给液配管，其入侧开口配设在所述辅助储液区域内并且其出侧开口配设在所述制冰皿的上侧；
所述辅助储液区域配设在所述制冰皿上方，
通过所述给液泵从所述储液区域向所述辅助储液区域供给的液体在重力的作用下在所述给液配管内向下流，从而向所述制冰皿供给。
根据本发明，向辅助储液区域供给的液体在重力的作用下在给液配管内向下流，从而向制冰皿供给。由此，当停止给液泵并终止向制冰皿的给液时，从储液区域一直到制冰皿的液体连接在辅助储液区域中断，并且给液配管内的液体全部向制冰皿流出。由此，即使采用不能逆向转动的非容积式泵作为给液泵，并且也不设置将外部气体导入给液配管的开口，也能够防止由虹吸现象引起的逆流。此外，由于为了不发生虹吸现象而进行隔绝的辅助储液区域与储液区域一样配设在储液箱体内，因此不会受到外部环境引起的污染。
如上所述，根据本发明，能够提供即使使用不能逆向转动的泵作为给液泵也能以保持清洁的状态向制冰皿供给储存在储液区域中的液体的给液装置。
进一步的，在本发明一实施方式中，在本发明的给液装置中，所述辅助储液区域具有倾斜的底面，从所述储液区域供给液体的供给口配设在所述底面的倾斜上侧，并且所述给液配管的所述入侧开口配设在所述底面的倾斜下侧。
根据本发明，从储液区域供给液体的供给口配设在辅助储液区域的倾斜的底面的倾斜上侧，并且给液配管的所述入侧开口配设在倾斜下侧。这样，在停止给液泵并终止向制冰皿的给液时，能够经由给液配管向制冰皿供给辅助储液区域内的全部液体。由此，液体不会残留在辅助储液区域中，从而能够保持辅助储液区域的清洁。
进一步的，在本发明一实施方式中，在本发明的给液装置中，所述给液配管由以下部分构成：
具有所述入侧开口并从所述储液箱体向外侧延伸的第一配管；以及
具有所述出侧开口并配设在配管箱体内的第二配管；
由所述给液泵的配设在所述配管箱体内的驱动部经由磁耦合以非接触方式驱动所述给液泵的配设在所述储液箱体内的泵主体，
在相对于所述储液箱体可装卸的所述配管箱体安装在所述储液箱体上的状态下，所述第一配管的在所述入侧开口相反侧的第一连接部与所述第二配管的在所述出侧开口相反侧的第二连接部彼此嵌合，
所述磁耦合成为驱动传递状态。
根据本发明，具有储液区域、给液泵的泵主体、辅助储液区域和第一配管的储液箱体与具有给液泵的驱动部和第二配管的配管箱体以可装卸的方式构成，因此能够容易地进行给液装置的保养和清洗。特别地，通过将给液配管分割成第一配管和第二配管并为给液泵采用磁耦合，能够容易地装卸储液箱体和配管箱体。
进一步的，在本发明一实施方式中，在本发明的给液装置中，所述第一配管从所述储液箱体向斜下侧延伸，
所述第二配管的所述第二连接部具有弹性，
当大致水平地移动拆下的所述配管箱体以接近所述储液箱体从而将其安装到所述储液箱体时，
弹性变形的所述第二连接部沿着所述第一配管的延伸方向以覆盖所述第一连接部的外表面的方式前进，以成为嵌合状态，
所述磁耦合的驱动部侧部分以接近泵主体侧部分的方式前进，以成为驱动传递状态。
为了在给液泵停止时第一配管内不残留液体，第一配管从储液箱体向斜下侧延伸。另一方面，为了磁耦合的泵主体侧部分和驱动部侧部分 以能传递驱动的方式配设，需要配管箱体大致水平地移动接近储液箱体。此时，由于第二连接部弹性变形，因此即使配管箱体大致水平地移动，第二连接部也能沿第一配管的延伸方向以覆盖第一连接部的外表面的方式前进。
这样，只需要大致水平地移动配管箱体，就能使第一配管和第二配管准确地嵌合，同时能将磁耦合的泵主体侧部分和驱动部侧部分配设为能传递驱动。
为实现上述发明目的，本发明一实施方式提供一种冰箱，所述冰箱包括上述任一实施方式所述的给液装置，包括上述给液装置的冰箱同样也能取得上述给液装置的各种效果。
如上所述，本发明中能够提供即使使用不能逆向转动的泵作为给液泵也能以保持清洁性的状态向制冰皿供给储存在储液区域中的液体的给液装置和包括该给液装置的冰箱。

(本发明的一个实施例所涉及的给液装置)
图1A至图1C是示意性地示出本发明的一个实施例所涉及的给液装置2的侧面截面图，图1A是示出储液箱体4与配管箱体6分离的状态的图，图1B是示出将配管箱体6安装到储液箱体4上期间的状态的图，并且图1C是示出配管箱体6安装在储液箱体4上的状态的图。图2是示意性地示出连接给液泵30的泵主体32与驱动部34的磁耦合36的结构的侧面截面图。
首先参考图1A至图2来说明本发明的一个实施例所涉及的给液装置2的结构。本发明的一个实施例所涉及的给液装置2包括储液箱体4和配管箱体6。储液箱体4和配管箱体6可彼此装卸。
<储液箱体>
储液箱体4的内部下侧配设有用于储存向制冰皿50供给的液体的储液区域10。作为向制冰皿50供给的液体，可以使用以饮用水为代表的任意液体。储液箱体4内部的储液区域10上方的位置配设有辅助储液区域20。
在储液箱体4的内部还配设有用于向辅助储液区域20供给储存在储液区域10中的液体的给液泵30的泵主体32。磁耦合36的泵主体侧部分36A安装在泵主体32的叶轮32A的旋转轴上。如后文所述，由配设在配管箱体6处的驱动部34经由磁耦合36来驱动泵主体32的叶轮32A。
泵主体32位于储液区域10内，吸入口在储存在储液区域10中的液体中开口。泵主体32的吐出口连接到泵出侧配管38。泵出侧配管38的出侧的端部在辅助储液区域20中开口，并且形成向辅助储液区域20供给储存在储液区域10中的液体的给液口38A。
辅助储液区域20具有倾斜的底面22，供给口38A配设在底面22的倾斜上侧。另一方面，具有入侧开口42A的第一配管42连接到底面22的倾斜下侧。入侧开口42A是第一配管42的上游侧的端部开口，并且成 为用于从辅助储液区域20向制冰皿50供给液体的给液配管40的上游侧的端部开口。如图1A所示，第一配管42沿底面22的倾斜向斜下侧延伸，并在指定的长度处终止。这样，第一配管42被形成为从储液箱体4向外侧延伸。此外，第一配管42的在入侧开口42A相反侧的下游侧的端部区域称为第一连接部42B。
<配管箱体>
配管箱体6的内部配设有与上述第一配管42一起构成给液配管40的第二配管44。第二配管44的下游侧的端部开口成为配设在制冰皿50的上侧的出侧开口44A。第二配管44的在出侧开口44A相反侧的上游侧的端部区域称为第二连接部44B。第二配管44从出侧开口44A大致竖直地延伸，在其上侧弯曲大致90度，形成第二连接部44B。如图1A所示，在配管箱体6没有安装在储液箱体4上的状态中，第二连接部44B沿大致水平的方向延伸。
在配管箱体6安装在储液箱体4上的状态中，第一配管42的第一连接部42B与第二配管44的第二连接部44B成为彼此嵌合的状态。第二连接部44B由与第一连接部42B嵌合的顶端部44B1和弹性部44B2构成。这样，第二连接部44B具有弹性。弹性部44B2优选地由包括硅的富有柔软性的树脂材料形成。在将配管箱体6安装到储液箱体4上时，通过弹性部44B2弹性变形，第二连接端部44B倾斜，能够与向斜下侧延伸的第一连接部42B顺利地嵌合。
配管箱体6的内部下侧配设有给液泵30的驱动部34，其为电动马达。磁耦合36的驱动部侧部分36B安装在驱动部34的驱动轴上。在配管箱体6安装在储液箱体4上时，驱动部34的驱动轴与泵主体32的叶轮32A的旋转轴被配设成同轴排列。
<磁耦合>
图2中示出了配管箱体6安装在储液箱体4上并且磁耦合36的泵主体侧部分36A和驱动部侧部分36B成为驱动传递状态时的情况。安装在泵主体32的叶轮32A的旋转轴上的磁耦合36的泵主体侧部分36A具有磁性。安装在驱动部34的驱动轴上的磁耦合36的驱动部侧部分36B具有与泵主体侧部分36A的南北极相逆的极性的磁性。这样，借助于泵主体侧部分36A与驱动部侧部分36B之间的磁力，使得驱动部34的驱动力 以非接触的状态传递至泵主体32的叶轮32A的旋转轴。
通过从图2所示的状态将储液箱体4大致水平地向与配管箱体6分离的方向(图中左侧)移动，从配管箱体6拆下储液箱体4，同时能够分离构成磁耦合36的泵主体侧部分36A和驱动部侧部分36B。另一方面，通过将拆下的储液箱体4大致水平地向接近配管箱体6的方向(图中右侧)移动，将储液箱体4安装到驱动箱体6上，同时能够将磁耦合36配设为驱动传递状态。
<储液箱体和配管箱体的装配>
接下来按顺序参考图1A至图1C来说明将拆下的配管箱体6安装到储液箱体4上的情况。通过从图1A所示的状态开始将配管箱体6大致水平地向接近储液箱体4的方向(参考箭头A)移动，配管箱体6上侧的装入部6A插入储液箱体4的引导孔。随着通过引导孔引导位置，当配管箱体6进一步接近储液箱体4时，配设在配管箱体6处的第二配管44的第二连接部44B的顶端与配设在储液箱体4处的第一配管42的第一连接部42B的顶端抵接。
图1B示出了从第一连接部42B和第二连接部44B的顶端抵接的状态开始将配管箱体6推至更加接近储液箱体4时的情况。如图1B的箭头A所示，在大致水平地推配管箱体6时，磁耦合36的驱动部侧部分36B沿箭头A的方向前进，从而接近泵主体侧部分36A。然后如图1C所示，当到达了配管箱体6的抵接面6B与储液箱体4的抵接面4B抵接的位置时，磁耦合36成为了驱动力传递状态。
如图1B的箭头A所示，当从第一连接部42B和第二连接部44B的顶端抵接的状态开始大致水平地推配管箱体6时，第二连接部44B的弹性部42B2弹性变形。然后如图1B的箭头B所示，第二连接部44B的顶端部42B1沿向斜下侧延伸的第一配管42的延伸方向以覆盖第一连接部42B的外表面的方式前进。然后如图1C所示，当到达了配管箱体6的抵接面6B与储液箱体4的抵接面4B抵接的位置时，第一配管42的第一连接部42B与第二配管44的第二连接部44B成为完全嵌合的状态。
这样就将配管箱体6安装到了储液箱体4上，使给液泵30的磁耦合36成为驱动力传递状态，并且使第一配管42与第二配管44嵌合，使给液配管30成为一体化的状态。由此，本实施例所涉及的给液装置2成为 了能够运转的状态。
在本实施例中，从防止在给液配管40处泄漏液体的角度出发，下游侧的第二连接部44B以覆盖上游侧的第一连接部42B的外表面的方式与之嵌合。然而不限于此，只要能够确保第一连接部42B和第二连接部44B之间的密封性，第一连接部42B以覆盖第二连接部44B的外表面的方式与之嵌合的情况也是可以的，或者第一连接部42B和第二连接部44B的端部以抵接的方式彼此连接的情况也是可以的。无论何种情况，由于第二连接部44B具有弹性，即使配管箱体6大致水平地移动，也能够与向斜下侧延伸的第一连接部42B顺利地嵌合、接合。
如上所述，在本实施例所涉及的给液装置2中，给液配管40由具有入侧开口42A且从储液箱体4向外侧延伸的第一配管42和具有出侧开口44A且配设在配管箱体6内的第二配管44构成，由给液泵30的配设在配管箱体6内的驱动部34经由磁耦合36以非接触方式驱动给液泵30的配设在储液箱体4内的泵主体32，在相对于储液箱体4可装卸的配管箱体6安装在储液箱体4上的状态下，第一配管42的在入侧开口42A相反侧的第一连接部42B与第二配管44的在出侧开口44A相反侧的第二连接部44B彼此嵌合，使得磁耦合36成为驱动传递状态。
根据本实施例，具有储液区域10、给液泵30的泵主体32、辅助储液区域20和第一配管42的储液箱体4与具有给液泵30的驱动部34和第二配管44的配管箱体6以可装卸的方式构成，因此能够容易地进行给液装置2的保养和清洗。特别地，通过将给液配管40分割成第一配管42和第二配管44并为给液泵30采用磁耦合36，能够容易地装卸储液箱体4和配管箱体6。
进一步地，第一配管42从储液箱体4向斜下侧延伸，第二配管44的第二连接部44B具有弹性，当大致水平地移动拆下的配管箱体6以接近储液箱体4从而将其安装到储液箱体4时，弹性变形的第二连接部44B沿第一配管42的延伸方向以覆盖第一连接部42B的外表面的方式前进，以成为嵌合状态，并且磁耦合36的驱动部侧部分36B以接近泵主体侧部分36A的方式前进，以成为驱动传递状态。
为了在给液泵30停止时第一配管42内不残留液体，第一配管42从储液箱体4向斜下侧延伸。另一方面，为了磁耦合36的泵主体侧部分 36A和驱动部侧部分36B以能传递驱动的方式配设，需要配管箱体6大致水平地移动接近储液箱体4。此时，由于第二连接部44B弹性变形，因此即使配管箱体6大致水平地移动，第二连接部44B也能沿第一配管42的延伸方向以覆盖第一连接部42B的外表面的方式前进。
这样，只需要大致水平地移动配管箱体6，就能使第一配管42和第二配管44准确地嵌合，同时能将磁耦合36的泵主体侧部分36A和驱动部侧部分36B配设为能传递驱动。
(给液装置中的液体流动)
图3是示意性地示出在本发明的一个实施例所涉及的给液装置2中向制冰皿50供给储液区域10的液体时的情况的侧面截面图。图4是示意性地示出在本发明的一个实施例所涉及的给液装置2中停止了向制冰皿50供给储液区域10的液体的状态的侧面截面图。接下来参考图3和图4来说明给液装置2中的液体流动。
如图3所示，在给液泵30运转时，向位于上方的辅助储液区域20供给储存在储液区域10中的液体。使用低成本且易于维护的非容积式泵作为给液泵30。更具体地，可以采用以旋涡泵为代表的离心泵或者以轴流泵为代表的螺旋泵。向辅助储液区域20供给的液体在重力的作用下沿作为斜面的底面22流动，从入侧开口42A流入给液配管40。然后，液体在给液配管40内向下流，从出侧开口44A向制冰皿50供给。
由于给液配管40的横截面积比辅助储液区域20的流动正交方向上的横截面积小，因此液体会一定程度上滞留在辅助储液区域20内。滞留在辅助储液区域20内的液体的容量由给液泵30的吐出量、辅助储液区域20的容积、给液配管40的内径(横截面积)等决定。优选地确定给液泵30的吐出量、辅助储液区域20的容积、给液配管40的内径(横截面积)等以达成适当的容量。作为滞留在辅助储液区域20内的液体的容量，可以举例50cc以上200cc以下的范围。
辅助储液区域20的底面22倾斜，并且与辅助储液区域20连接的给液配管40的第一配管42沿底面22的倾斜向斜下侧延伸，因此使向辅助储液区域20供给的液体有效地流动，从而向制冰皿50供给。作为底面22相对于水平面的倾斜角度，可以举例10度以上30度以下的范围。不但有第一配管42延伸的倾斜角度与底面22的倾斜角度一致的情况，也 可以有比底面22的倾斜角度小的情况或者比其大的情况。无论何种情况，第一配管42优选为不水平或竖直，而是向斜下侧延伸。
在向制冰皿50供给了指定量的液体后，停止给液泵30的运转。由于辅助储液区域20的底面22倾斜、第一配管42向斜下侧延伸、并且更下游侧的第二配管44大致竖直地延伸，因此向辅助储液区域20供给的液体基本上全部向制冰皿50流动并落下。由此，如图4所示，液体从储液区域10经过泵主体32充满至泵出侧配管38的箭头C所示的位置，而不会残留在辅助储液区域20或给液配管40中。这样，能够保持辅助储液区域20和给液配管40的清洁。
如上所述，本实施例所涉及的给液装置2包括：储液箱体4；配设在储液箱体4内的用于储存向制冰皿50供给的液体的储液区域10；配设在储液箱体4内的在储液区域10上方的辅助储液区域20；给液泵30，其是非容积式泵，用于向辅助储液区域20供给储存在储液区域10中的液体；以及给液配管40，其入侧开口42A配设在辅助储液区域20内并且其出侧开口44A配设在制冰皿50的上侧；辅助储液区域20配设在制冰皿50上方，通过给液泵30从储液区域10向辅助储液区域20供给的液体在重力的作用下在给液配管40内向下流，从而向制冰皿50供给。
向辅助储液区域20供给的液体在重力的作用下在给液配管40内向下流，从而向制冰皿50供给。由此，当停止给液泵30并终止向制冰皿50的给液时，从储液区域10一直到制冰皿的液体连接在辅助储液区域20中断，并且给液配管40内的液体全部向制冰皿50流出。由此，即使采用不能逆向转动的非容积式泵作为给液泵30，并且也不设置将外部气体导入给液配管40的开口，也能够防止由虹吸现象引起的逆流。此外，由于为了不发生虹吸现象而进行隔绝的辅助储液区域20与储液区域10一样配设在储液箱体4内，因此不会受到外部环境引起的污染。
由此，在本实施例所涉及的给液装置2中，即使使用不能逆向转动的泵作为给液泵30，也能以保持清洁的状态向制冰,50供给储存在储液区域10中的液体。
特别地，在本实施例所涉及的给液装置2中，辅助储液区域20具有倾斜的底面22，从储液区域10供给液体的供给口38A配设在底面22的倾斜上侧，并且给液配管40的入侧开口42A配设在底面22的倾斜下侧。
这样，在停止给液泵30并终止向制冰皿50的给液时，能够经由给液配管40向制冰皿50供给辅助储液区域20内的全部液体。由此，液体不会残留在辅助储液区域20内，从而能够保持辅助储液区域20的清洁。
(本发明的一个实施例所涉及的包括给液装置的冰箱)
图5是示意性地示出本发明的一个实施例所涉及的包括给液装置2的冰箱100的侧面截面图。冰箱100中包括冷冻室102和冷藏室104，给液装置2配设在冷藏室104处，并且制冰皿50配设在冷冻室102内。冰箱内的气体通过风扇108而流动，通过了蒸发器106而被冷却的冷气流入冷冻室102。通过给液装置2向制冰皿50供给的液体被该冷气所冷却并冻结，从而产生冰。
包括该给液装置2的冰箱100也能取得上述给液装置的各种效果。
尽管说明了本发明的实施例和实施方式，但是公开内容可以在结构的细节方面有所变化，并且也可以实现实施例、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。
