洗碗设备以及减振安装组件 技术领域
本主题总体上涉及洗碗设备，并且更具体地涉及具有用于限制其中振动的一个或更多个组件的洗碗设备。
背景技术
洗碗机或洗碗设备一般包括桶，其限定了用于接收用于清洗的物品的清洗腔室。门提供或允许进入该清洗腔室的选择性入口。在清洗或漂洗周期期间，洗碗设备通常使流体通过清洗腔室在物品(比如，罐、盘、银餐具等)上循环。该流体可以是，例如清洗周期期间的水与洗洁剂的各种组合或者漂洗周期期间的水(其可以包括添加剂)。在漂洗周期完成之后，可以执行排水周期，以从清洗腔室中移除流体。通常，提供有一个或更多个泵来驱使流体穿过清洗腔室或从中离开。例如，洗碗设备中的流体通常使用循环泵来在给定周期期间循环。流体被收集在清洗腔室的底部处或其附近的集液槽中，并且通过例如喷洒臂中的喷嘴或引导流体对着待清洁或漂洗的物品的其它开口被泵回到清洗腔室中。在漂洗周期完成之后，可以启动排水泵以将流体泵送到清洗腔室外部。
通常，循环泵与排水泵直接安装到限定清洗腔室的桶。泵与桶之间一般需要水密密封。为了精确度和强度的目的，通常需要相对硬的接触点来将泵的马达支撑在清洗桶上。
这些现有布置存在若干缺点。例如，循环泵和排水泵的长期存在的问题之一是在它们的使用期间振动的生成。典型的系统使用一个或更多个O形环，所述O形圈可以形成水密密封，但通常在减振方面不起作用。随着时间的推移，这些振动可能导致在洗碗设备的桶或其它部分上形成裂缝。最终，可能会产生泄漏点或故障点。附加地或替代地，当马达或其安装结构接触桶时，振动可能 导致生成过大的噪音。
因此，提供一种解决一个或更多个上述认定的问题的洗碗设备将是有用的。特别地，提供一种包括用于振动隔离或以其它方式减小从泵组件传递到桶的振动的幅度的安装特征的洗碗设备可能是有利的。

具体实施方式
现在将详细参考本发明的实施例，其一个或多个示例在附图中示出。提供每个示例是为了解释本发明，而不是限制本发明。事实上，对于本领域技术人员来说显而易见的是，在不脱离本发明的范围或精神的情况下，可以在本发明中进行各种修改和变型。例如，作为一个实施例的一部分示出或描述的特征可以与另一个实施例一起使用，以产生又一个实施例。因此，本发明旨在覆盖落入所附权利要求及其等同物的范围内的这些修改和变型。
如本文所用，术语“或”通常旨在是包括在内的(即，“A或B”旨在意指“A或B或两者”)。术语“第一”、“第二”和“第三”可以互换使用以将一个部件与另一个区分开，并且不旨在表明各部件的位置或重要性。术语“上游” 和“下游”是指相对于流体路径中的流体流的相对流动方向。例如，“上游”指流体从其流动的流动方向，而“下游”指流体流向其的流动方向。
图1和图2描绘了根据本公开的示例性实施例的洗碗设备100。如图1所示，洗碗设备100包括柜体102。柜体102在其中具有限定清洗隔间106的桶104。桶104还限定了前部开口(未示出)。洗碗设备100包括门120，所述门铰接在门120的底部122处，用于在通常封闭竖直位置(在图1和2中示出)与水平打开位置之间移动，在通常封闭竖直位置处清洗隔间106被密封关闭以用于清洗操作，所述水平打开位置用于从洗碗设备100中装载或卸载物品。在一些实施例中，闩锁123用于锁定和解锁门120以进入清洗隔间106。桶104还包括集液槽170，其邻近桶104的底部部分112定位并构造成在洗碗设备100的操作期间接收液体清洗流体(例如，水、洗洁剂，清洗流体、或任何其它合适流体)。
在某些实施例中，管口160邻近洗碗设备100的集液槽170定位。管口160构造成用于将液体引导到集液槽170中。管口160可以接收来自例如水供给(未示出)或任何其它合适的源的液体。在替代实施例中，管口160可以定位在洗碗设备100内的任何合适位置(例如，使得管口160将液体引导到桶104中)。管口160可以包括阀(未示出)，使得液体可以选择性地引导到桶104中。因此，例如，在下文描述的周期期间，管口160可以根据洗碗设备100的当前周期的需要将水或清洗流体选择性地引导到集液槽170中。
支架组件130和132可以可滑动地安装在清洗隔间106内。在一些实施例中，支架组件130和132中的每个被制造成包括多个细长构件134的网格结构。支架组件130和132中的每个支架总体上适于在延伸装载位置(未示出)和收回位置(在图1和2中示出)之间移动，在延伸装载位置，支架基本上定位在清洗隔间106的外部，在收回位置，支架位于清洗隔间106的内部。银餐具篮(未示出)可以可移除地附接至支架组件132，以用于放置银餐具、用具及类似物，否则它们太小而不能被支架130和132容纳。
在某些实施例中，洗碗设备100包括下部喷洒组件144，其可旋转地安装在 清洗隔间106的下部区146内并位于集液槽170上方，以便相对地接近支架组件132旋转。可选地，中间位置喷洒组件148位于清洗隔间106的上部区中并且可以定位成接近上部支架130。附加地或替代地，上部喷洒组件150可以位于上部支架130上方。
在示例性实施例中，下部和中间位置喷洒组件144和148以及上部喷洒组件150由流体循环组件152供给，用于使水和洗碗机流体在桶104中循环。流体循环组件152包括一个或更多个流体泵(例如，循环泵154或错流/排水泵156)。如下面将更详细讨论的，一些实施例包括至少部分地定位在集液槽170内的循环泵154和定位在循环泵154下方并与集液槽170流体连通的排水泵。附加地，排水泵156可以构造成用于在启动时促使从集液槽170到排水口158的清洗流体的流动。相比之下，循环泵154可以构造成用于在启动时通过一个或更多个循环导管226将来自集液槽170的清洗流体的流动供给到喷洒组件144、148和150。此外，过滤组件也可以至少部分地定位在集液槽170中，以用于在这种清洗流体流动到循环泵154之前从该清洗流体过滤食物颗粒或其它碎片(本文中统称为污物)。
喷洒组件144和148包括排放喷嘴或孔口的布置，用于将清洗流体引导到位于支架组件130和132中的餐具或其它物品上。喷洒组件144和148中的排放喷嘴的布置借助于流动穿过排放端口的清洗流体来提供旋转力。喷洒组件144和148的形成的旋转通过喷洒清洗流体来提供对餐具和其它洗碗机内容物的覆盖。
洗碗设备100进一步配备有控制器137，以调节洗碗设备100的操作。控制器137可以包括存储器(例如，不可转移介质)和微处理器，比如可操作为执行与清洗操作相关的编程指令或微控制代码的通用或专门用途的微处理器。存储器可以表示随机存取存储器(比如DRAM)，或只读存储器(诸如ROM或FLASH)。在一个实施例中，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，或者可以被包括搭载在处理器内。替代地，可以在 不使用微处理器的情况下来构造控制器137(例如，使用分立的模拟或数字逻辑电路的组合，比如开关、放大器、积分器、比较器、触发器、与门等)来执行控制功能而不是依赖软件。
控制器137可以遍及洗碗设备100定位在各种位置中。在示出的实施例中，控制器137可以位于如所示的门120的控制面板区域121内。在这样的实施例中，输入/输出(“I/O”)信号可以沿着线束在洗碗设备100的控制器137与各个操作部件之间路由，所述线束可以通过门120的底部122引出。通常，控制器137包括用户界面面板136，用户可以通过该用户界面面板来选择各种操作特征和模式并监测洗碗设备100的进程。在一个实施例中，用户界面136可以表示通用用途I/O(“GPIO”)装置或功能块。在一个实施例中，用户界面136可以包括输入部件，比如各种电气、机械或机电输入装置(包括旋转拨盘、按钮和触摸板)中的一个或更多个。用户界面136可以包括显示部件，比如被设计成向用户提供操作反馈的数字或模拟显示装置。用户界面136可以经由一个或更多个信号线或共享通信总线与控制器137通信(例如，电气通信或有线通信)。
应当理解，本文公开的主题不限于洗碗设备的任何特定样式、模型或构造，并且附图中描绘的实施例仅用于说明性用途。例如，代替图1所描绘的支架130和132，洗碗设备100可以具有利用抽屉的已知构造，所述抽屉从柜体中拉出并可以从顶部进入以用于物品的装载和卸载。
现在转向图3至9，图3和6至9提供了集液槽170的各种视图，包括泵组件200和用于该泵组件的壳体234。图4和5提供了与集液槽170隔离的泵组件200的部分的各种视图。
如上所述，集液槽170沿着竖直方向V定位在桶104(图2)的底部部分112处。集液槽170限定了轴向方向A，该轴向方向可以，例如平行于竖直方向V。可选地，集液槽170与桶104的底壁142一体地形成。然而，在其它实施例中，集液槽170可以替代地与桶104的底壁142分开地形成，并且以任何合适的方式附接至桶104的底壁142。附加地，集液槽170可以具有任何合适的取向。
如所示的，集液槽170包括侧壁202和底壁204。侧壁202可以沿着轴向方向A限定大致圆柱形的形状，尽管在其它实施例中，侧壁202可以替代地沿着轴向方向A限定任何其它合适的形状，比如截头圆锥形状或者替代地倒置截头圆锥形状。
在示例性实施例中，底壁204从侧壁202径向向内延伸并限定了由壁202和204界定的凹陷腔室206。凹陷腔室206在其周边处通过底部壁204的向下延伸的边沿部分而被大体向下地限定(例如，朝向轴向方向A或平行于轴向方向A)。凹陷腔室206还限定了开口210，其具有例如大体圆形的形状。此外，底壁204在打开进入到凹陷腔室206中的部分限定了排水开口208。
在一些实施例中，过滤器组件沿着轴向方向A至少部分地定位在集液槽170中(例如，作为泵组件200的一部分或与其一起)。过滤器组件可以包括多个面板，比如侧部面板212、底部面板214、或顶部面板(未示出)。侧部面板212、底部面板214、和顶部面板中的一个或更多个可以包括过滤器介质，所述过滤器介质限定了多个开口或孔洞，所述多个开口或孔洞构造成允许清洗流体从其穿过同时防止污物(比如，大于预定尺寸的食物颗粒或其它碎片)从其穿过。例如，在某些实施例中，侧部面板212、底部面板214、和顶部面板中的一个或更多个可以包括细网目材料。
在示例性实施例中，循环泵154包括在泵组件200中。更具体地，循环泵154包括流体叶轮(例如，循环叶轮232)和腔室泵壳体234。当组装时，循环叶轮232定位在泵组件200中，并且被腔室泵壳体234封闭。在一些实施例中，循环泵154、包括腔室泵壳体234通过一个或更多个弹性体立柱222沿着轴向方向A保持就位。在某些实施例中，泵壳体234限定了多个引导管236，所述引导管在叶轮232的下游，并且与循环导管226流体连通(图2)。引导管236因此可以将来自循环叶轮232的清洗流体的流动F引导至循环导管226(例如，在循环周期期间)。在示例性实施例中，循环泵154至少部分地定位在过滤器组件内(例如，在其一个或更多面板内)。
如下面将更详细描述的，一些实施例包括安装在集液槽170的一部分内的电马达242。例如，电马达242可以封闭在腔室泵壳体234的一部分内。
当组装时，一个或更多个弹性体立柱222在腔室泵壳体234和集液槽170的底壁204之间大体上竖直地或以其它方式平行于轴向方向A。更具体地，对于所描绘的实施例，一个或更多个弹性体立柱222从腔室泵壳体234穿过凹陷腔室206延伸至集液槽170的底壁204。如所示的，腔室泵壳体234可以保持或支撑在弹性体立柱222上。例如，腔室泵壳体234可以包括围绕腔室泵壳体234周向定位(例如，相对于引导管236径向向外)的一个或更多支撑管子250。每个支撑管子250可以大体对应并选择性地接收弹性体立柱222中的一个。当被接收在支撑管子250中时，弹性体立柱222可以提供与腔室泵壳体234的支撑性接合。特别地，腔室泵壳体234的基本上全部质量或重量可以引导至弹性体立柱222或以其它方式由其承载。
在可选实施例中，至少一个弹性体立柱222和对应支撑管子250形成了配对电气插头-插座252。例如，至少一个弹性体立柱222可以包括电气公插头252A，而对应的支撑管子250包括电气母插座252B。替代地，电气公插头252A可以被设置在支撑管子250中，而母插座252B被设置在弹性体立柱222上或内。弹性体立柱222可以与电源导电连通或电气连通(例如，通过一个或更多个中间传导导线或总线)。支撑管子250可以与电马达242导电连通或电气连通。在组装时，配对的电气插头-插座252可以将电源连接至电马达242。因此可以通过至少一个弹性体立柱222与电马达242形成电连接。
在一些实施例中，泵组件200包括排水泵156，其自身包括流体叶轮(例如，排水叶轮238)以及排水泵壳体240。当组装时，排水叶轮238可以被排水泵壳体240封闭，并且排水泵壳体240附接到集液槽170或以其它方式由其形成。更具体地，排水泵壳体240定位在由集液槽170组件的底壁204限定的凹陷腔室206下方并通过集液槽170的底壁204的排水开口208与其流体连通。在某些示例性实施例中，排水泵壳体240可以与集液槽170一体地形成，或者替代 地可以以任何合适的方式附接至集液槽170。
如所示，涡形盖254可以定位成跨过排水口208的至少一部分或位于其上方。在一些实施例中，涡形盖254安装到腔室泵壳体234(例如，经由一种或更多种粘合剂、机械紧固件或一体的单个构件)。当组装时，涡形盖254因此可以(例如，沿着轴向方向A)定位在电马达242与排水叶轮238之间。盖开口或入口256限定成穿过涡形盖254(例如，沿着轴向方向A或者沿着平行于竖直方向V的方向或以其它方式非正交于竖直方向V的方向)。凹陷腔室206与排水泵壳体240之间的流体连通与流动F可以因此被允许通过盖入口256。
在一些实施例中，涡形盖254包括径向凸缘258(例如，沿涡形盖254的径向周边或外周边)。例如，径向凸缘258可以在涡形盖254的径向最外部分处绕着轴向方向A布置。在组装时，径向凸缘258可以至少部分地定位在绕着排水开口208或在其附近延伸的弹性体密封件260的上方。
如所示，弹性体密封件260可以在通常相对于竖直方向V或轴向方向A高于排水叶轮238的位置处安装在集液槽170上(例如，安装在底壁204上)。弹性体密封件260可以进一步至少部分地沿着轴向方向A定位在径向凸缘258和凹陷腔室206之间(或在径向凸缘258与排水叶轮238之间)。在一些实施例中，弹性体密封件260包括环形支撑主体262和从其延伸的界面表面264。例如，界面表面264可以从环形支撑主体262朝向轴向方向A径向向内延伸。在可选实施例中，界面表面264相对于轴向方向A以非正交角度θ延伸。例如，非正交可以在相对于轴向方向A的30°与80°之间，使得界面表面264总体上从环形支撑主体262上下降至在轴向方向A的近侧处的自由端部(即，相比于环形支撑主体262或环形支撑主体262的界面表面264从其延伸的部分在径向上更靠近轴向方向A)。可选地，径向凸缘258的下部面(例如，径向凸缘258的定向为朝向界面表面264的表面)可以限定互补角度，其等于或在非正交角度θ的10°之内。替代地，径向凸缘258可以限定与非正交角度θ不同的角度，其相对于轴向方向A在30°与90°之间。
在组装时，界面表面264可以通常占据与径向凸缘258重叠的印迹。换句话说，界面表面264和径向凸缘258可以在从垂直于轴线方向A的平面观察时呈现为重叠。环形支撑主体262可以从涡形盖254处径向地向外定位。可选地，环形支撑主体262的至少一部分可以(例如，相对于竖直方向V和轴向方向A)比涡形盖254延伸得高。例如，环形支撑主体262的最高部分可以比涡形盖254的最高部分沿着竖直方向更靠近底壁142。界面表面264可以大体向上面向，使得界面表面264被引导朝向径向凸缘258。在一些这样的实施例中，弹性体立柱222将腔室泵壳体234以及由此的涡形盖254保持在弹性体密封件260的至少一部分的上方。当电马达242未启动或排水叶轮238以其它方式保持在非旋转状态时，可以在界面表面264与径向凸缘258的底部表面之间形成轴向间隙。相比之下，当电马达242启动并且排水叶轮238在凹陷腔室206中旋转时，界面表面264可以被迫使与径向凸缘258接合或接触(比如直接接触)，使得在其间形成流体密封。
值得注意的是，大部分(如果不是全部)从腔室泵壳体234传递至集液槽170的在结构上显著的振动可以通过弹性体立柱222被引导。有利地，涡形盖254可以相对于集液槽170大体保持在振动隔离位置处。
在一些实施例中，泵组件200包括与电马达242接合(例如，机械连接)的轴向轴244。在操作期间，轴向轴244可以因此通过电马达242旋转。如所示，电马达242可以(例如沿着竖直方向V或轴向方向A)定位在排水叶轮238或循环叶轮232上方。此外，循环叶轮232可以定位在涡形盖254上方。在示例性实施例中，轴向轴244沿着轴向方向A延伸穿过循环叶轮232，穿过涡形盖254(例如在盖入口256处)并且进入到排水叶轮238中。轴向轴244可以与排水叶轮238和循环叶轮232选择性地接合(机械连接)，从而轴向轴244的旋转使排水叶轮238旋转或使循环叶轮232旋转。
在可选实施例中，循环泵154可以包括与循环叶轮232和轴向轴244机械连接的单向离合器(未示出)。当轴向轴244通过电马达242在第一方向上旋转 时，循环叶轮232的单向离合器构造成接合循环叶轮232并使循环叶轮232旋转。替代地，循环叶轮232可以固定至轴向轴244(例如，从而轴向轴242在第一方向或第二方向上的旋转使循环叶轮232旋转)。
在附加或替代实施例中，排水泵156进一步包括与排水叶轮238和轴向轴244机械连接的单向离合器268。当轴向轴244通过电马达242在第二方向(第二方向为第一方向的相反方向)上旋转时，排水叶轮238的单向离合器268构造成接合排水叶轮238并使排水叶轮238旋转。在一些这样的实施例中，在给定时间，仅循环泵154和排水泵156中的一个可以被启动。替代地，排水叶轮238可以固定至轴向轴244(例如，从而轴向轴242在第一方向或第二方向上的旋转使排水叶轮238旋转)。
有利地，包括电马达242和叶轮232、238的本发明过滤器组件可以通过将腔室泵壳体234降低到集液槽170中而被组装，不需要在凹陷腔室206下方区域中的单独的电马达，或者不需要进入该区域。附加地或替代的，泵组件200的大部分(如果不是全部)(例如电马达242、腔室泵壳体234、涡形盖254、以及叶轮232、238)可以在被安装在集液槽170中之前被预组装。
现在参考特别是图8，集液槽170被描绘为在循环泵154(图2)的操作期间，比如示例性洗碗设备100的循环周期期间(例如清洗或漂洗周期)。在循环泵154的操作期间，通道246可以限定在过滤器组件的底部面板214与集液槽170的底壁204之间。如所示，通道246可以进一步在底部面板214与涡形盖254之间延伸。通道246通常允许清洗流体进入过滤器组件的底部面板214。因此，在循环泵154的操作期间，循环泵154的叶轮232可以拉动清洗流体的流动F穿过过滤器组件(例如，穿过顶部面板、侧部面板212、或底部面板214，使得清洗流体向内流动穿过面板)。
在循环泵154的操作期间，清洗流体中的污物可以受重力作用而朝向限定在集液槽170的底壁204中的凹陷腔室206。例如，循环泵154的入口248邻近过滤器组件的底部面板214定位，并且因此清洗流体可以首先被拉动穿过过滤 器组件的底部面板214。附加地或替代地，因为凹陷腔室206定位在集液槽170的底部处，所以重力还可以导致污物受重力作用而朝向凹陷腔室206。由于排水开口208通向由底壁204限定的凹陷腔室206，因此这种构造可以允许集液槽170的高效排水和清洁。如所示，底壁204可以包括或被设置为实心连续表面。因此，底壁204的至少一部分(例如，直接在凹陷腔室206和叶轮238下方的其最下部表面)可以没有水可以穿过的开口或穿孔(例如，竖直开口)。
现在参考特别是图9，集液槽170被描绘为在排水泵156(图2)的操作期间，比如示例性洗碗设备100的排水周期期间。在排水泵156的操作期间，清洗流体的流动F可以从集液槽170被拉动穿过集液槽170的底壁204中的凹陷腔室206，并且穿过底壁204的排水泵开口208。由于许多污物可以定位在凹陷腔室206中，所以排水泵156可以更快速地排出先前收集在底壁204的凹陷腔室206中的污物，并且可以留下较少的污物用于随后的循环。
本书面描述使用示例来公开本发明，包括最佳模式，并且还使本领域任何技术人员能够实践本发明，包括制造和使用任何装置或系统以及执行任何结合的方法。本发明的专利范围由权利要求限定，并且可包括本领域技术人员想到的其它示例。如果这样的其他示例包括不与权利要求的字面语言不同的结构元件或者如果它们包括与权利要求的字面语言无实质差异的等同结构元件，则这些其他示例意图在权利要求的范围内。
