Definitions

  • the present invention relates generally to refrigeration appliances, and more particularly to systems and methods for detecting water leaks in refrigeration appliances.
  • Refrigeration appliances typically include a cabinet defining a refrigerated compartment. A variety of food items can be stored in the refrigerated compartment. The low temperature of the refrigerated compartment relative to the ambient atmosphere helps to extend the shelf life of food products stored in the refrigerated compartment.
  • refrigeration appliances typically include a dispensing assembly for providing water and/or ice to a user, and a water filter assembly is often used to filter this water prior to use.
  • some water filtration assemblies include a cartridge having a housing and filter media therein. Unfiltered water flows into the cartridge housing, while filtered water flows out of the cartridge housing.
  • the filter media can be activated carbon blocks, pleated polymer sheets, spun string materials, or meltblown materials.
  • a filter medium is disposed within the housing and filters water passing therethrough.
  • Water leaks may develop or occur at one or more different locations in or around the water filtration assembly, such as where the cartridge is mounted to the manifold. Such leaks may arise, for example, if the water filter assembly is improperly installed or exposed to relatively high water pressure or freezing conditions. Such leaks can negatively affect the operation of the water filter assembly and/or refrigeration appliance, and may cause damage if not prevented. Such leaks are also difficult to detect. In particular, water filter assemblies are often located in relatively remote locations within refrigeration appliances, so that visual monitoring of water filter assembly leaks may be difficult or infrequent. As another example, existing leak detection systems and methods typically rely on direct detection of leaks, eg, the leaking water must be in direct physical contact with the sensor in order for the sensor to detect the leak. As a result, leaks at locations remote from the sensor may be delayed in detection or not detected at all.
  • a refrigeration appliance with an improved filter assembly would be useful. More specifically, filters that can be used to detect water leaks would be particularly beneficial.

  • the method also includes calculating a rate of change over time of at least one of water pressure in the water filter and flow through the water filter.

Description

带嵌入式漏水传感器的制冷电器水过滤器 技术领域
本发明总体涉及制冷电器，更具体地涉及用于检测制冷电器中的漏水的系统和方法。
背景技术
制冷电器通常包括限定制冷间室的箱体。多种食品可以储存在制冷间室内。制冷间室相对于环境大气的低温有助于延长储存在制冷间室内的食品的保质期。
另外，制冷电器通常包括用于向用户提供水和/或冰的分配组件，并且水过滤组件经常用于在使用之前过滤这种水。例如，某些水过滤组件包括具有壳体和在其中的过滤介质的滤芯。未过滤的水流入滤芯的壳体，而过滤的水流出滤芯的壳体。过滤介质可以是活性炭块、折叠聚合物片材、纺制细绳材料或者熔喷材料。过滤介质设置在壳体内，并过滤通过其中的水。
在水过滤组件中或周围的一个或多个不同位置(诸如在滤芯安装到歧管的位置)处可能形成或产生漏水。作为示例，如果水过滤组件不正确地安装或者暴露于相对高的水压或冷冻条件，则可能产生这种泄漏。这种泄漏会对水过滤组件和/或制冷电器的运行产生负面影响，并且如果不加以防止，可能会造成损坏。这种泄漏也很难检测到。特别地，水过滤组件通常设置在制冷电器内的相对远处的位置，使得视觉地监测水过滤组件的泄漏可能是困难的或很少发生的。作为另一个示例，现有的泄漏检测系统和方法通常依赖于泄漏的直接检测，例如，泄漏的水必须与传感器直接物理接触，以便传感器检测泄漏。由此，在远离传感器的位置处的泄漏可能延迟检测或根本检测不到。
因此，具有改进的过滤组件的制冷电器将是有用的。更具体地，可以用于检测漏水的过滤器将是特别有益的。

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或者精神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是制冷电器100的示例性实施方式的前视图。图2是制冷电器100的立体图。图3是制冷电器100的前视图，其中其食物保鲜门体128处于打开位置。制冷电器100在顶部101与底部102之间沿着竖向V延伸。制冷电器100也在第一侧105与第二侧106之间沿着侧向L延伸。如图2所示，横向T可以另外被限定为垂直于竖直V和侧向L。制冷电器100在前部108与后部110之间沿着横向T延伸。
制冷电器100包括箱体或壳体120，该箱体或壳体限定上部食物保鲜室122(图3)和沿着竖向V布置在食物保鲜室122下方的下部冷冻室或冷冻食物储存室124(图1)。因为冷冻室124设置在食物保鲜室122下方，所以制冷电器100通常被称为底置式冰箱。在示例性实施方式中，壳体120还限定了用于接收密封冷却系统(未示出)的机械室(未示出)。使用本文所公开的示教，本领域技术人员应当理解,本技术也可以与其它类型的冰箱(例如，对开门式)或冷冻电器一起使用。因此，本文阐述的描述仅出于例示目的，而无意于在任何方面限制该技术。
冷藏门体128各自可旋转地铰接到壳体120的边缘，以便进入食物保鲜室122。应当注意，虽然示例了“法式门”构造的两个门体128，但是利用一个、两个或更多个门体的任意合适的门体布置都在本发明的范围和精神内。在冷藏门体128的下方布置冷冻门体130，以便进入冷冻室124。在示例性实施方式中，冷冻门体130联接至可滑动地安装在冷冻室124内的冷冻抽屉(未示出)。还设置有辅助门体127，并且辅助门体127可滑动地安装在设置在新鲜食物储存室122与冷冻室124之间的辅助室(未示出)内。如在图3中可以看到的，多个食物储存抽屉140可以布置在新鲜食物储存室122内。尽管没有特别标记，但是在图3中还可以看到诸如盒和层 架的额外示例性食物储存部件。
如图2示例，在一些实施方式中，制冷电器100可以包括供水管道150。供水管道150可以被构造为将制冷电器100联接至供水系统(诸如管道系统)，由此，供水管道150从供水系统接收水，并将水输送至制冷电器100的各种其他部件(诸如制冰机和/或水分配器)。制冷电器100还可以包括主阀152，当主阀152处于打开位置时，该主阀152允许水流过供水管道150，并且当主阀152处于关闭位置时，该主阀152防止或阻碍水流过供水管道150。
制冷电器100的操作可以由控制器134(图1)来调节，该控制器134可操作地联接到用户界面面板136。界面面板136提供用于用户操纵制冷电器100的操作以修改其中的环境条件的选择，诸如温度选择等。在一些实施方式中，用户界面面板136可以接近分配器组件132。响应于用户对用户界面面板136的操作，控制器134操作制冷电器100的各种部件。制冷电器100的操作可以由控制器134调节，例如，控制器134可以响应于用户界面面板136的编程和/或用户操纵来调节制冷电器100的各种部件的操作。
控制器134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冷电器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。应当注意，如本文所公开的控制器134能够并且可以运行为执行如本文所公开的任意方法和关联的方法步骤。
控制器134可以设置在整个制冷电器100中的各种位置。在所示例的实施方式中，控制器134可以位于门体128内。在这种实施方式中，输入/输出(“I/O”)信号可以在控制器150与制冷电器100的各种操作部件之间路由。在一个实施方式中，用户界面面板136可以表示通用I/O(“GPIO”)装置或功能块。在一个实施方式中，用户界面136可以包括输入部件，诸如包括旋转拨号盘、按钮以及触摸板的各种电气、机械或机电输入装置中的一个或多个。用户界面136可以包括显示部件，诸如设计为向用户提供操作反馈的数字或模拟显示装置。例如，用户界面136可以包括提供输入和显示功能两者的触摸屏。用户界面136可以经由一条或多条信号线或共享的通信总线与控制器通信。
使用本文公开的示教，本领域技术人员应当理解，本发明可以与其它类型的冰箱一起使用，诸如冰箱/冰柜组合、对开门式、底置式、紧凑型和任意其它样式或 型号的制冷电器。因此，可以提供制冷电器100的其它构造，应当理解，附图所示的构造和本文中阐述的描述仅作为示例性目的。
在一些实施方式中，例如，如图4示例，制冷电器100可以包括连接到其的水过滤器200。例如，水过滤器200可联接到供水管道150(图2)，使得水过滤器200从供水管道150接收水流1000(例如，可被称为生水或未过滤水)，并且将水流1002(例如，过滤水)提供到供水管道150的在过滤器200下游的部分和/或制冷电器100的各种固定装置或部件(诸如制冰机或水分配器等)。水过滤器200可包括限定内部容积的壳体202，该壳体具有通过壳体202通向内部容积的入口204和从内部容积出来的出口208。如图4示例，未过滤的水1000可经由入口204流入过滤器200。然后，水可以穿过过滤介质206(例如膜、活性炭或包括多于一种介质的组合的其他合适的过滤介质)，从而产生过滤水1002，该过滤水经由出口208离开水过滤器200。
传感器210可以嵌入在水过滤器200中。特别地，传感器210可以嵌入在水过滤器200的壳体202中。例如，在一些实施方式中，传感器210可以嵌入在壳体202内，使得传感器210在至少四侧上被壳体202的材料围绕。在一些实施方式中，传感器210可以嵌入在壳体202内，使得传感器210在五侧上被壳体202的材料围绕并且仅在传感器210的一侧上暴露。传感器210的唯一暴露侧可暴露于过滤器200的内部，使得传感器210的唯一暴露侧暴露于通过制冷电器100的预期水流路的一部分，并且传感器210因此被沿着预期水流路流动的水部分地润湿。例如，在图4所示例的实施方式中，传感器210在一侧暴露于流过过滤器200的入口204的水，其中，入口204是预期水流路的一部分。预期水流路可至少部分地由供水管道150和水过滤器200限定，诸如由供水管道150和联接到其的各种配件、固定装置和/或部件(例如水过滤器200、阀152、制冰机、水分配器等)限定。而且，预期水流路和其中的水将被理解为与可能的泄漏路径和泄漏的水不同，例如，泄漏的水可以包括从预期的水流路逸出并在预期的水流路之外的水。泄漏的水可能在沿着预期水流路的任何点(在传感器210的上游或下游)处逸出，并且如下文更详细地描述的，可被传感器210检测到，而不管泄漏的水从沿着预期水流路的哪个或哪些点逸出。在其它实施方式中，传感器210可在两侧暴露，包括如上所述暴露于预期流路的一侧和部分暴露的第二侧，以便允许传感器210与控制器134之间的物理连接(诸如经由如下所述的引脚212)。
在一些实施方式中，传感器210可以被配置为与控制器136无线通信，例如， 传感器210可以无线地(诸如通过蓝牙连接)连接到控制器134。在其它实施方式中，可以设置与传感器210通信的一个或多个电源引脚212或其它合适的有线连接点，由此，传感器210可以经由有线连接与控制器134可操作地通信。在这样的实施方式中，传感器210可以嵌入在壳体202内，除了有线连接点(例如电源引脚212)，其中，传感器210的有线连接点从壳体202暴露和/或延伸通过壳体202或延伸到壳体202外部。
在一些实施方式中，传感器210可以是微机电系统(MEMS)传感器。传感器210可以是任何合适的传感器，其可以足够小以嵌入在壳体202内，同时还测量和/或监测(例如，随时间重复地或连续地测量)过滤器中的水压和/或流经过滤器的流量。通过测量压力和/或流量，传感器210可以在不直接检测泄漏的情况下检测到泄漏，例如，在传感器210与泄漏的水之间没有直接的物理接触。由此，传感器210可以用单个传感器检测水系统中任何位置(传感器210的上游或下游)处的泄漏，例如，与需要在多个位置安装多个传感器以便检测大多数或所有可能的泄漏相反。在所示例的示例性实施方式中，传感器210在入口204处嵌入在壳体202中，使得传感器210测量入口压力和流经入口的流量。在另外的实施方式中，传感器210可以嵌入在壳体202的任何其它部分中，以测量壳体202的这种其它部分处的局部压力。在至少一些实施方式中，本文所述的泄漏检测基于压力随时间的变化，而不考虑测量压力的位置或绝对压力如何。传感器210可以基于随时间的变化来检测泄漏，例如由传感器210测量的随时间的流量增大和/或压力的减小。例如，传感器210可以与控制器134可操作地通信，如上所述，从而使传感器210和控制器134检测泄漏，诸如通过用传感器210测量压力和/或流量，并用控制器134计算压力和/或流量的变化率。然后，例如基于压力变化率的增大(例如压力更快地下降)和/或流量变化率的增大(例如流量更快地增大)，可检测到泄漏。
现在转到图5，本发明的实施方式可以包括检测制冷电器中的泄漏的方法300，该制冷电器诸如为上述示例性制冷电器100。例如，如上所述，制冷电器可以包括控制器和具有嵌入式传感器的水过滤器。如图5示例，在一些实施方式中，方法300可包括步骤301：利用嵌入在水过滤器中的传感器测量水过滤器中的水压；和步骤302：利用嵌入在水过滤器中的传感器测量流经水过滤器的流量。然后，可以将测量值发送到制冷电器的控制器并由其接收。例如，如图5示例，方法300还可以包括步骤304：从传感器接收压力测量值和流量测量值，并且接收步骤可以由制冷电器的控制器执行。在一些实施方式中，例如，如图5中的步骤306示例，方法300随后 可包括基于所接收的压力测量值和流量测量值来检测泄漏。例如，可以响应于并且由于所接收的压力测量值和流量测量值(例如作为压力测量值和流量测量值的识别的变化的结果)来检测泄漏。另外，无论泄漏是否到达传感器或者过滤器的嵌入传感器的部分，都可检测到泄漏。例如，可以到检测泄漏，而不要求泄露的水在检测泄漏之前接触到传感器。
如上所述，可以基于压力和/或流量的变化来检测泄漏。例如，在一些实施方式中，检测泄漏的示例性方法还可包括通过随时间接收多个压力测量值来监测水过滤器中的水压；以及通过随时间接收多个流量测量值来监测流经水过滤器的流量。在这样的实施方式中，方法还可以包括计算多个所接收的压力测量值随时间的变化率；以及计算多个所接收的流量测量值随时间的变化率。由此，在一些实施方式中，检测泄漏的步骤可以基于多个所接收的压力测量值随时间的变化率的增大(例如压力更快地下降)以及多个所接收的流量测量值随时间的变化率的增大(例如流量更快地增加)中的至少一个。
在一些实施方式中，可以基于(例如响应于)附加条件以及多个所接收的压力测量值随时间的变化率和多个所接收的流量测量值随时间的变化率中的至少一个的增大来检测泄漏。例如，当不存在对来自水系统的水的需求时，诸如仅当不存在对水的需求时并且响应于压力的变化率的增大(例如，压力更快地下降)和/或流量的变化率的增大(例如，流量更快地加速)而对水没有需求时，可检测到泄漏。由此，在一些实施方式中，检测制冷电器中的泄漏的示例性方法还可以包括：在所接收的压力测量值随时间的变化率和所接收的流量测量值随时间的变化率中的至少一个增加之后，且在检测到泄漏之前，确定是否存在对水的系统需求。
在一些实施方式中，方法还可以包括当检测到泄漏时的一个或多个补救步骤，例如，作为所检测的泄漏的结果并响应于所检测的泄漏。例如，方法可以包括在检测到泄漏之后关闭制冷电器的主阀。作为另一示例，该方法还可以或替代地包括在检测到泄漏之后经由制冷电器的用户界面提供用户通知，该用户界面例如可以是上述用户界面面板136或可以是用户界面面板136的显示部件。
图6示例了检测制冷电器中的泄漏的另外的示例性方法400。制冷电器可包括供水管道、联接到供水管道的水过滤器、以及嵌入在水过滤器中的传感器。如图6示例，方法400可包括步骤402：通过嵌入在水过滤器中的传感器测量水过滤器中的水压和流经水过滤器的流量中的至少一个。在一些实施方式中，测量步骤402可包括利用嵌入在水过滤器中的传感器测量水过滤器中的水压和流经水过滤器的流量。
方法400还可包括步骤404：计算水过滤器中的水压和流经水过滤器的流量中的至少一个随时间的变化率。步骤402和404可以是迭代的或重复的，例如，可以连续地或重复地测量压力和/或流量，并且可以监测或跟踪变化率，例如，基于新的测量值周期性地重新计算变化率。在监测变化率的同时，当水过滤器中的水压和流经水过滤器的流量中的至少一个随时间的变化率增大时，方法可包括响应于水过滤器中的水压和流经水过滤器的流量中的至少一个随时间的变化率增大来确定是否存在对水的系统需求，例如，如图6中的步骤408示例。如上所述，变化率的增大可以包括例如开始更快地下降的压力下降和/或开始更快地加速的流量加速。在一些实施方式中，例如，在测量步骤402包括如上所述测量压力和流量两者的情况下，计算步骤404可包括计算水过滤器中的水压随时间的变化率和流经水过滤器的流量随时间的变化率。在这样的实施方式中，确定步骤408可以响应于水过滤器中的水压随时间的变化率的增大或者流经水过滤器的流量随时间的变化率的增大中的任一者或两者来执行。
在步骤408确定是否存在对水的系统需求之后，并且当确定为“否”时，如图6示例，方法400随后可包括当不存在对水的系统需求时基于随时间的变化率的增大来检测泄漏。
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。
