Description

用于独立制冰器的清洗排出管道 技术领域
本发明总体涉及制冰器，更具体地涉及无排出的独立制冰器。
背景技术
制冰器通常包括构造为产生冰的制冰机。制冰器内的制冰机被管接到供水系统，并且来自供水系统的水可流到制冰器内的制冰机。制冰器通常由密封系统冷却，并且制冰机中的液态水与密封系统的制冷剂之间的热传递产生冰。
在某些制冰器中，储存在制冰器内的冰随着时间的推移而融化并产生液态融水。通常，制冰器被管接到外部排出管(例如，连接到市政水系统)以处理液态融水。而且，在制冰器内执行清洗操作之后，使用管接的排出管来处理清洁溶液。虽然对于管理液态融水是有效的，但是外部排出管道具有缺点。例如，安装外部排出管道可能困难且昂贵。另外，清洁这种制冰器可能繁重且耗时。
最近，已经引入了管接排出管的可选方案。然而，这些可选方案具有某些缺点。例如，手动排出管的位置对于用户来说不方便，从而导致在执行手动排出时的不愉快体验。而且，在执行清洁和排出操作之后收集和处理清洁溶液困难且笨拙。
因此，消除一个或多个上述缺点的制冰器将是有用的。特别地，具有更高效的清洗过程的制冰器将是有益的。

在本发明的另一个示例性方面，提供了一种制冰器。该制冰器可以包括：箱体，该箱体形成储冰室；第一储存容器，该第一储存容器设置在储冰室内，第一储存容器被构造为接收液体；可去除格栅，该可去除格栅位于第一储存容器上方的储冰室内；制冰机，该制冰机设置在储冰室内以制冰；以及循环系统，该循环系统与第一储存容器流体连通。循环系统可以包括：供应管路管道；泵，该泵连接到供应管路管道以从第一储存容器泵送液体；以及清洗管路管道，该清洗管路管道与泵流体连通，清洗管路管道设置在泵的下游，其中，泵选择性地将液体从第一储存容器泵送通过清洗管路管道。
参照下文的描述以及所附权利要求，本发明的这些和其它的特征、方面以及优点将变得更容易理解。结合在本说明书中并且构成本说明书一部分的附图显示了本发明的实施方式并且与描述一起用于对本发明的原理进行解释。
附图说明
参照附图，说明书中阐述了面向本领域普通技术人员的本发明的完整公开，这种公开使得本领域普通技术人员能够实现本发明，包括本发明的最佳实施例。
图1提供了根据本发明的示例性实施方式的制冰器的前立体图。
图2提供了图1的示例性制冰器的前立体图，其中示例性制冰器的门体被示出为处于打开位置。
图3提供了根据第一实施方式的图1的示例性制冰器的侧面示意图。
图4提供了根据另一实施方式的图1的示例性制冰器的侧面示意图。
附图标记在本说明书和附图中的重复使用旨在表示本发明的相同或相似的特征或元件。
具体实施方式
现在将详细地参照本发明的实施方式，其中的一个或多个示例示于附图中。每个示例都以对发明进行解释的方式给出，并不对本发明构成限制。实际上，对于本领域技术人员而言显而易见的是，能够在不偏离本发明的范围的前提下对本发明进行多种改型和变型。例如，作为一个实施方式的一部分示出或者进行描述的特征能够用于另一个实施方式，从而产生又一个实施方式。因此，期望的是，本发明覆盖落入所附权利要求及其等同形式的范围内的这些改型以及变型。
图1和图2提供了根据本发明的示例性实施方式的制冰器100的前立体图。如 下面更详细所述，制冰器100包括用于生成或产生透明冰的特征。由此，制冰器100的用户可以消耗在制冰器100内储存的透明冰。如在图1中可以看到的，制冰器100限定竖向V。
制冰器100包括箱体110。箱体110可以是隔热的，以便限制箱体110的内部容积111(图2)与周围大气之间的热传递。箱体110在顶部112与底部114之间延伸，例如，沿着竖向V延伸。由此，箱体110的顶部112和底部114彼此隔开，例如，沿着竖向V隔开。门体119安装到箱体110的前部。门体119允许选择性地进入箱体110的内部容积111。例如，门体119在图1中被示出为处于关闭位置，并且门体119在图2中被示出为处于打开位置。用户可以使门体在打开位置与关闭位置之间旋转，以进入箱体110的内部容积111。
如在图2中可以看到的，制冰器100的各种部件设置于在箱体110的内部容积111内。特别地，制冰器100包括布置在箱体110的内部容积111内的制冰机120，例如布置在箱体110的顶部112处。制冰机120用于产生透明冰。制冰机120可用于制造任何合适类型的透明冰。由此，如将理解的，例如，制冰机120可以是透明冰块制冰机。
制冰器100还可包括储冰室或储冰盒102。储冰室102可以设置在箱体110的内部容积111内。特别地，储冰室102可以沿着竖向V设置在例如制冰机120的正下方。由此，储冰室102被设置为从制冰机120接收透明冰，并且用于在其中储存透明冰。可以理解，储冰室102可以保持在高于水的冰点的温度。由此，储冰室102内的透明冰可能在储存在储冰室102内的同时随着时间的推移而融化。制冰器100可包括用于使液态融水从储冰室102再循环到制冰机120的特征。
图3提供了制冰器100的某些部件的示意图。如在图3中可以看到的，制冰机120可以包括冰模具124和喷嘴126。例如，冰模具124可以包括用于同时形成多个冰块的多个冰模具。来自喷嘴126的液体可以朝向冰模具124分配。例如，喷嘴126可以设置在第一储存容器128内的冰模具124下方，并且可以朝向冰模具124向上分配液态水。如以下更详细所述，冰模具124由制冷剂冷却。由此，来自喷嘴126的流经冰模具124的液态水可以在冰模具124上冻结，例如，以便在冰模具124上形成透明冰块。
为了冷却冰模具124，制冰器100包括密封系统170。密封系统170包括用于执行已知的用于冷却制冰机120和/或空气的蒸汽压缩循环的部件。这些部件包括串联连接并填充有制冷剂的压缩机172、冷凝器174、膨胀装置(未示出)以及蒸发器176。 如本领域技术人员将理解的，密封系统170可以包括其他部件，例如，至少一个额外的蒸发器、压缩机、膨胀装置和/或冷凝器。另外或可选地，可以根据特定实施方式来调节部件(例如，压缩机172、冷凝器174等)的放置。由此，密封系统170仅以示例的方式来提供。使用密封系统的其他构造也在本发明的范围内。
在密封系统170内，制冷剂流入压缩机172中，该压缩机运行为增大制冷剂的压力。制冷剂的该压缩升高其温度，该温度通过使制冷剂穿过冷凝器174来降低。在冷凝器174内，进行与周围空气的热交换，以便冷却制冷剂。风扇178可以运行为将空气吹过冷凝器174，以便提供强制对流，用于冷凝器174内的制冷剂与周围空气之间进行更快且高效的热交换。
膨胀装置(例如，阀、毛细管或其他限制装置)接收来自冷凝器174的制冷剂。制冷剂从膨胀装置进入蒸发器176。在离开膨胀装置并进入蒸发器176时，制冷剂的压力下降。由于制冷剂的压降和/或相变，蒸发器176是冷的，例如，相对于环境空气和/或液态水。蒸发器176设置在制冰机120处并与其热接触，例如设置在制冰机120的冰模具124处。由此，制冰机120可在蒸发器176处用制冷剂直接冷却。
应当理解，在可选示例性实施方式中，制冰机120可以是空气冷却制冰机。由此，例如，来自蒸发器176的冷却空气可对制冰器100的各种部件进行制冷，例如对制冰机120的冰模具124进行制冷。在这种示例性实施方式中，蒸发器176是一种热交换器，该热交换器将热量从经过蒸发器176的空气传递到流经蒸发器176的制冷剂，并且风扇可使冷空气从蒸发器176循环到制冰机120。
制冰器100还可包括控制器190，该控制器调节或操作制冰器100的各种部件。控制器190可以包括存储器和一个或多个微处理器、CPU等，诸如通用或专用微处理器，该微处理器用于执行与制冰器100的运行关联的编程指令或微控制代码。存储器可以表示诸如DRAM的随机存取存储器或诸如ROM或FLASH的只读存储器。在一个实施方式中，处理器执行存储在存储器中的编程指令。存储器可以是与处理器分开的部件，或者可以包含在处理器内的板上。可选地，控制器190可以在不使用微处理器的情况下，例如，使用离散的模拟或/或数字逻辑电路的组合(诸如开关、放大器、积分器、比较器、触发器、与门等)构建为执行控制功能，而不是依靠软件。输入/输出(“I/O”)信号可以在控制器190与制冰器100的各种操作部件之间路由。作为示例，制冰器100的各种操作部件可以经由一条或多条信号线或共享的通信总线与控制器190通信。
制冰器100可以包括第一储存容器128。第一储存容器128可设置在储冰室102 内。例如，第一储存容器128可位于储冰室102的内部容积111的顶部112处或附近。第一储存容器128可限定保持待形成为冰的液体(例如水)的接收空间。例如，第一储存容器128的内部容积可小于储冰室102的内部容积111。在一些实施方式中，第一储存容器128可保持其它液体，例如清洁溶液。如将在下面更详细地解释的，第一储存容器128可为可去除的(例如，从储冰室102去除)。例如，第一储存容器128可包括相对于箱体110可拆卸的特征，诸如抽屉滑轨、磁体、夹子等。因此，第一储存容器128可从箱体110的内部容积111去除。
制冰机120可设置在第一储存容器128内。详细地，蒸发器176和冰模具124可以位于第一储存容器128内。在一些实施方式中，制冰机120设置在第一储存容器128上方(例如，沿着竖向V)。第一储存容器128可沿着竖向V从底端202延伸到顶端。制冰机120可安装在第一储存容器128的顶端处。例如，蒸发器176可以安装到顶端，并且冰模具124可以连接到蒸发器176。在一些实施方式中，冰模具124可由蒸发器176限定。换言之，蒸发器176与冰模具124成一体，使得透明冰直接形成在蒸发器176上。
制冰器100可包括循环系统139。循环系统139可包括第一泵142、供应管道140和喷嘴126。第一泵142可设置在第一储存容器128内。第一泵142可以泵送储存在第一储存容器128中的水或液体。供应管道140可连接到第一泵142，使得由第一泵142泵送的水或液体循环通过供应管道140。供应管道140可包括一系列能够引导由第一泵142泵送的水或液体的管或管道。喷嘴126可设置在供应管道140的下游端。喷嘴126可将储存在第一储存容器128中的水或液体朝向制冰机120(即，冰模具124和/或蒸发器176)分配。
在一个实施方式中，喷嘴126可以位于第一储存容器128的底端202附近。由此可见，水或液体可从喷嘴126沿大体向上的方向朝向制冰机120喷射。因此，在制冰机120由通过密封系统170的制冷剂的循环冷却的同时，由于水持续地喷射到制冰机120上，因此可在制冰机120上形成透明冰。详细地，从喷嘴126分配的液体可以被引向冰模具124。在一些实施方式中，可以提供多个喷嘴126。多个喷嘴126中的每一个可独立地连接到第一泵142(例如，各个喷嘴126具有专用的供应管道140)。另外或可选地，多个喷嘴126中的每一个可经由联合循环管道连接到第一泵142。
第一液位传感器134可设置在第一储存容器128中。通常，第一液位传感器134可感测容纳在第一储存容器128内的液位。在一些实施方式中，第一液位传感器134 与控制器190可操作地通信。比如，第一液位传感器134可经由一个或多个信号与控制器190通信。在某些实施方式中，第一液位传感器134包括预定阈值料位(例如，以指示对第一储存容器128的额外液体的需要)。特别地，第一液位传感器134可检测第一储存容器128的液体是否或何时低于预定阈值料位。可选地，第一液位传感器134可以是双位置传感器。换言之，第一液位传感器134可以是“开”或“关”，这取决于液位。
例如，当液位低于预定阈值料位时，第一液位传感器134“关闭”，这意味着其不经由控制器190向第一泵142发送信号以通过第一供应管道140从第一储存容器128朝向第一喷嘴126泵送液体。再如，当液位高于预定阈值时，第一液位传感器134“开启”，这意味着其经由控制器190向第一泵142发送信号以操作第一泵142，从而通过第一供应管道140朝向第一喷嘴126泵送液体。应当理解，第一液位传感器134可以是能够确定第一储存容器128内的液位的任何合适的传感器，并且本发明不限于本文提供的这些示例。
制冰器100也可以清洁模式操作，或者可以执行清洁操作，以清洁制冰器100中可能被外来碎屑污染的各种件。例如，在一些实施方式中，清洁溶液或酸可被泵送通过第一供应管道140并由喷嘴126朝向制冰机120分配。因此，清洁溶液或酸可以从例如冰模具124、喷嘴126、第一储存容器128和供应管道140去除外来污染物或碎屑。
制冰器100还可包括第二储存容器138。第二储存容器138可与储冰室102流体连通。排出管道150可将储冰室102与第二储存容器138连接，使得来自储冰室102的液体流入第二储存容器138中。在一些示例中，第二储存容器138设置在储冰室102下方。换言之，第二储存容器138可沿竖向V位于储冰室102下方。因此，来自储冰室102的液体可容易地经由排出管道150流入第二储存容器138中。在一个示例中，当储存在储冰室102内的冰融化成水时，融水的至少一部分可从储冰室102通过排出管道150流入第二储存容器138中。第二储存容器138也可与第一储存容器128流体连通。换言之，来自第二储存容器138的液体可流到第一储存容器128。在一个示例中，第二储存容器138经由回流管路管道152连接到第一储存容器128。在使用期间，来自第二储存容器138的融水的至少一部分可被泵送至第一储存容器，以通过第一供应管道140再循环并重新分配到制冰机120上。
第二泵144可以设置在第二储存容器138处或中。在使用期间，第二泵144可以选择性地将融水的至少一部分从第二储存容器138泵送到第一储存容器128。通常， 第二泵144可以被设置为任何合适的流体泵(例如，旋转泵、往复泵、蠕动泵、速度泵等)。可选地，第二泵144可以是潜水泵并且可以位于第二储存容器138内。详细地，第二泵144可以可浸没在第二储存容器138内(即，在储存在第二储存容器138内的一定体积的液体内)。另外或可选地，第二泵144可位于第二储存容器138的外部。换言之，第二泵144可以在第二储存容器138的边界之外，使得第二泵144不与储存在第二储存容器138内的液体直接接触。有利地，第二泵144可以辅助使液体再循环通过制冰器100，以提高性能并减少对清洁或维护的需要。
第二液位传感器136可设置在第二储存容器138内，以感测容纳在第二储存容器138内的液位。通常，第二液位传感器136可感测容纳在第二储存容器138内的液位。在一些实施方式中，第二液位传感器136与控制器190可操作地通信。比如，第二液位传感器136可经由一个或多个信号与控制器190通信。在某些实施方式中，第二液位传感器136包括预定阈值料位(例如，以指示对从第二储存容器138排出液体的需要)。特别地，第二液位传感器136可检测第二储存容器138中的液体是否或何时低于或高于预定阈值料位。可选地，第二液位传感器136可以是双位置传感器。换言之，第二液位传感器136可以是“开”或“关”，这取决于水位。
例如，当水位低于预定阈值料位时，第二液位传感器136“关闭”，这意味着其不经由控制器190向第二泵144发送信号以从第二储存容器138泵送水。再如，当水位高于预定阈值时，第二液位传感器136“开启”，这意味着其经由控制器190向第二泵144发送信号以操作第二泵144。应当理解，第二液位传感器136可以是能够确定第二储存容器138内的液位的任何合适的传感器。
制冰器100可包括溢流管路管道230。溢流管路管道230可将第一储存容器128与第二储存容器138流体连接。例如，溢流管路管道230可提供用于第一储存容器128内的流体或液体直接流入第二储存容器138的通道。溢流管路管道230的顶部232可设置在第一储存容器128内的常规液位线上方。详细地，如上所述，预定量的液体可储存在第一储存容器128内以制冰。溢流管路管道230的顶部232可以定位为使得高于预定体积的液体体积可以流入溢流管路管道230的顶部232中，由此流入第二储存容器138中。在一些实施方式中，溢流管路管道230的出口234部分地设置在排出管道150内。如下面将更详细地解释的，清洁液体或溶液可以从第一储存容器128通过溢流管路管道210流到第二储存容器138。
制冰器100还可包括清洗管路管道210。清洗管路管道210可以限定第一端212和第二端214。第一端212和第二端214中的每一个都限定了沿着通过清洗管路管道 210的流路的点。在一个示例中，第一端212连接到回流管路管道152。例如，第一端212可以限定清洗管路管道210从回流管路管道152的分支点。如上所述，回流管路管道152可以与第二储存容器138流体连接。因此，第二储存容器138内的液体可流出第二储存容器且选择性地流过清洗管路管道210。在一些实施方式中，来自第二储存容器138的流体经由第二泵144被推动通过回流管路管道152。因此，清洗管路管道210的第一端212可以设置在第二泵144的下游。术语“上游”和“下游”是指相对于流体通路中的流体流动的相对方向。例如，“上游”是指流体流动的来向，而“下游”是指流体流动的去向。因此，第二泵144可以将流体朝向清洗管路管道210泵送。
第二端214可以向外部区域敞开。换言之，第二端214可以敞开地露出(例如在制冰器100内或外)。流经清洗管路管道210的液体可经由第二端214从制冰器100释放。第二端214可设置在例如储冰室102内(例如可暴露在内部容积111内)。有利地，制冰器100内的各个部件可通过使清洁流体循环通过其中并通过清洗管路管道210排出清洁流体而容易地清洁。由此，可以执行更彻底的清洁，这导致更干净的冰、更少的维护问题和可操作性的总体增加。
清洗管路管道210可经由三通阀216与回流管路管道152流体连通。如图3所示，三通阀216可将第一泵144与回流管路管道152和清洗管路管道210流体连接。三通阀216可以是任何合适类型的阀。在至少一个示例中，三通阀216是机电阀。三通阀216可以与控制器190通信。例如，控制器190可以控制三通阀216的操作(例如，三通阀216的打开和关闭)。而且，控制器190可以例如在清洁操作或循环期间(例如，根据用户输入)一起控制三通阀216和第二泵144。
详细地，三通阀216可以选择性地允许来自第二储存容器138的液体流过回流管路管道152和清洗管路管道210中的一个。控制器190可以确定电器100处于第一模式，诸如制冰模式。因此，控制器190可以控制三通阀216以打开回流管路管道152并关闭清洗管路管道210。由此，当泵(例如，第二泵144)被启动时，第二储存容器138内的液体(例如，融水)通过回流管路管道152被泵送至第一储存容器128。而且，控制器190可确定电器100处于第二模式，诸如清洁模式或清洗模式。控制器190由此可以控制三通阀216以打开清洗管路管道210并关闭回流管路管道152。
另外或可选地，控制器190可以控制电器100执行清洗操作或清洁操作。根据清洗操作，供应到第一储存容器128的清洁液体(例如，清洁酸)可通过供应管道 140泵送。因此，清洁液体可以经由喷嘴126供应到例如冰模具124。在清洗操作期间，冰模具124可不被冷却(例如，制冷剂不经由密封系统170供应到蒸发器176)。清洁液体可例如由于重力而从冰模具124落入第一储存容器128和/或储冰盒102中。然后，清洁液体可以流入第二储存容器138(例如，经由下述溢流管或排出管道150)。
清洗操作可包括再循环。在再循环期间，控制器190可以控制三通阀216以打开回流管路管道152并关闭清洗管路管道210。因此，清洁液体可从第二储存容器138循环通过回流管路管道152并进入第一储存容器128。由此，循环系统的各个部分接收清洁液体。在执行一个或多个再循环之后，控制器190可以控制三通阀216以关闭回流管路管道152并打开清洗管路管道210。由此，第二泵144可以将清洁液体从第二储存容器138通过清洗管路管道210泵出。
清洗管路管道210可以包括清洗龙头218。清洗龙头218可以设置在清洗管路管道210的第二端214处。清洗龙头218可以选择性地从清洗管路管道210释放液体(例如，清洁液体)。例如，清洗龙头218可以选择性地打开和关闭第二端214。清洗龙头218可以包括阀。清洗龙头218可以手动操作(例如，通过扭转、拉动、推动、旋转或以其他方式操纵阀)以选择性地打开和关闭第二端214。由此，用户可以从清洗管路管道210释放液体(例如，清洁液体)。然而，应当注意，一些实施方式完全省略龙头218。详细地，第二端214可以是清洗管路管道210的无阻碍开口。因此，液体(例如，清洁液体)从清洗管路管道210的释放可以仅由三通阀216控制。
清洗管路管道210可至少部分地布置在储冰室102内。详细地，在从回流管路管道152分支(例如，经由三通阀216)时，清洗管路管道210可延伸到储冰室102中。如在图3中看到的，一部分清洗管路管道210可穿过储冰室102的底部。另外或可选地，清洗管路管道210可穿过储冰室102的侧壁。应当注意，清洗管路管道210的精确放置可以根据具体实施方式而变化，并且本发明不限于本文提供的示例。
例如，清洗管路管道210可沿竖向V和横向T(例如，朝向电器100的前部)延伸。由此，清洗龙头218可以设置在门体119附近。有利地，用户可以容易地接近清洗龙头216以完成清洗循环。然后，流经清洗管路管道210的液体(例如，清洁液体)在经由清洗龙头218(或者当省略清洗龙头216时通过第二端214)释放之后可以被处理。
在至少一个实施方式中，可去除的容器220可以选择性地放置在第二端214下方。例如，可去除的容器220可以类似于水罐。例如，可去除的容器220可形成为可去除地附接到储冰盒102。如在图3中看到的，用户可打开门体119并将可去除容 器220设置在储冰盒102内。在一些实施方式中，可去除的容器220包括支撑臂222。支撑臂222可以装配在储冰盒102的前唇缘上。因此，当液体被供应到可去除的容器220时，可去除的容器220可以被稳定地保持在适当的位置。然而，在其它实施方式中，可去除的容器220可自由地设置在储冰盒102内。例如，第二端214可以选择性地设置在内部容积111内(例如，设置在转环上)。因此，用户可以将第二端214设置在期望的位置，由此将可去除的容器220设置在对应的位置。可去除的容器220可以限定能够保持预定量的清洁液体的容积。在至少一个示例中，可去除的容器220保持执行充分清洁操作所需的液体体积。有利地，用户仅需要进行单个去除动作来完成清洁循环。
通常，控制器190可在发起清洁循环之前确定存在可去除的容器220(例如，在储冰室102内)。例如，在接收到(例如，来自用户的)输入信号以发起清洁循环或操作时，控制器可执行一个或多个预循环或预操作检查。根据一些实施方式，传感器或开关可存在于储冰室102内以感测或确认可去除容器220的存在。传感器可以向控制器190发送响应信号，该信号确认可去除的容器220的存在。控制器190然后可确定第一储存容器128内存在液体(例如，清洁酸、清洁溶液等)。例如，控制器190可以接收来自第一液位传感器134的确认第一储存容器128内存在液体的信号。然后，控制器190可以开始执行清洁循环或操作(例如，启动三通阀216、引导第二泵144等)
根据一些实施方式，可以省略或修改清洗龙头218。例如，可以修改清洗龙头216以将软管或额外管道接纳到龙头。软管可在其第一端处连接到清洗龙头216(或清洗管路管道210的第二端214)，并且在其第二端处设置在排出管处、中或附近。因此，也可以省略可去除的容器220。
在第一储存容器128上方(例如沿着竖向V)可设置穿孔的斜坡或一系列板条104。斜坡104可位于制冰机120下方(例如，在冰模具124或蒸发器176下方)。换言之，斜坡104可沿着竖向V位于制冰机120下方。斜坡104的顶面(或一系列板条的顶缘)可以是成角度的。换言之，斜坡104的第一端可在竖向V上设置得比斜坡104的第二端高。由此，当冰在制冰机120上形成并收获时，冰可落到斜坡104上并滑入储冰室102中。在一个示例中，如图3中看到的，斜坡104朝向箱体110的前部向下成角度。因此，可在第一储存容器128的一侧上设置通道或孔，冰块可在滑下斜坡104之后通过该通道或孔排出。另外或可选地，挡板或摆动门122可以与箱体110枢转地连接。详细地，当所收获的冰块滑下斜坡104时，它们可通过压 靠并打开挡板122而穿过第一储存容器128的通道。
制冰器100可包括供水管道130和供应阀132。供水管道130可连接到外部加压供水系统，诸如市政供水系统或井。供应阀132可以联接到供水管道130，并且供应阀132可以是可操作(例如，可打开和可关闭)的，以调节通过供水管道130进入制冰器100的液态水流。在一个实施方式中，供水管道130连接到第一储存容器128。详细地，供水管道130与第一储存容器128流体连通，以允许外部水经由供水管道130被供应到第一储存容器128中。由此，例如，通过打开供应阀132，第一储存容器128可通过供水管道130被填充有来自外部加压供水系统的新鲜液态水。供水管道130可以连接在箱体110的底部。在一些实施方式中，供水管道130连接在箱体110的顶部。根据该实施方式，通过箱体的顶部引入的水可在制冰机120的顶部上方释放，并且可辅助形成在冰模具124上的冰的收获操作。
制冰器100可包括过滤器154。过滤器154可嵌套在第一储存容器128内。例如，过滤器154可搁置在第一储存容器128内。在一些实施方式中，过滤器154悬挂在第一储存容器128内。详细地，可以在过滤器154的下侧与第一储存容器128的底部之间设置用于接收已经通过过滤器154的液体的空间。由此，过滤器154可以位于冰模具124的下方。例如，过滤器154可以设置为使得从喷嘴126分配的在冰模具124上未冻结的液体可以落在过滤器154的顶部上。因此，过滤器154可以是重力式过滤器。详细地，液体可落到过滤器154的顶部上，渗透通过过滤器154(例如，沿着竖向V)，并且通过过滤器154的底部离开。
图4提供了根据可选实施方式的制冰器的侧面示意图。与图3所示实施方式相同的附图标记适用于图4所示实施方式中的相同特征。由此可见，为了简洁，将省略对相同特征的重复描述。根据图4，第一储存容器128可设置在储冰室102的下方。例如，第一储存容器128可直接位于储冰室102的下方。可以设置格栅180，以将储冰室102与第一储存容器128分开。格栅180可以是可去除的格栅。例如，用户可将格栅180从储冰室102拉出，以接近第一储存容器128。因此，用户能够容易地从第一储存容器128去除过滤器154。另外或可选地，第二储存容器138和第二泵144中的每一个可被省略。有利地，可以并入更少的零件，并且可以实现储冰空间的增加(例如，更大的储冰室102)。根据该实施方式，清洗管路管道210可与供应管道140流体连通。详细地，清洗管路管道210的第一端212可以在泵142的下游附接至供应管道140。在一些实施方式中，三通阀216可以设置在供应管道140上。因此，清洗管路管道210的第一端212可以与三通阀216流体连通。
进一步地，根据图4的制冰器100可包括收集托盘182。收集托盘182可设置在冰模具124的下方。详细地，收集托盘182可收集在制冰操作(例如，当液体从喷嘴126朝向冰模具124分配时)或清洁操作或循环(例如，当清洁液体从喷嘴126朝向冰模具124分配时)期间和之后从冰模具124滴落的液体。另外或可选地，可以提供回流管道184。回流管道184可连接到收集托盘182(例如，在收集托盘182的底部处)。回流管道可沿着竖向V从收集托盘182朝向格栅180延伸。由此，收集于收集托盘182中的液体可返回到第一储存容器128，并且重新供应到过滤器154(或经由清洗管路管道210泵送出电器100)。
根据本文所述的实施方式，提供了一种具有清洗管道的制冰器。所述制冰器可以不直接管接到家用排出管，由此在放置和使用方面可以更通用。本文所述的制冰器可包括第一储存容器，该第一储存容器储存要在冰模具上形成冰的液体(诸如水)。第一储存容器还可选择性地储存清洁液体或溶液，诸如清洁酸。储存在第一储存容器中的液体可被引向冰模具。来自冰模具的多余液体可返回到第一储存容器。在一些情况下，多余的液体被输送到与第一储存容器分开的第二储存容器。第二储存容器可以经由回流管路管道将收集的液体重新供应到第一储存容器。回流管路管道上可包括三通阀。从三通阀分支的可以是清洗管路管道。根据具体应用，三通阀可以选择性地将液体从第二储存容器供应至回流管路管道或清洗管路管道。清洗管路管道可包括位于其下游端的清洗龙头。液体可以选择性地从清洗龙头释放。可去除的容器可放置在清洗龙头下方，例如在制冰器的储冰室内。然后，可以经由可去除的容器容易地处理分配的液体(诸如清洁溶液)。
本书面描述使用示例对本发明进行了公开(其中包括最佳实施例)，并且还使本领域技术人员能够实施本发明(其中包括制造和使用任意装置或系统并且执行所包含的任意方法)。本发明的可专利范围通过权利要求进行限定，并且可以包括本领域技术人员能够想到的其它的示例。如果这种其它的示例包括与权利要求的字面语言没有区别的结构元件，或者如果这种其它的示例包括与权利要求的字面语言没有实质区别的等同结构元件，则期望这种其它的示例落入权利要求的范围中。
