Description

具有用于干燥的热板加热器的洗碗器具 技术领域
本主题总体上涉及洗碗器具，更具体地说，涉及用于加热洗碗器具的组件和方法。
背景技术
现代洗碗器具(例如洗碗机)通常包括限定洗涤室的桶，例如，洗涤剂、水和热量可以施加在该洗涤室中，以便从被洗涤的碗碟和其他物品上清洁食物或其他材料。在洗涤和漂洗周期期间，洗碗机通常使流体通过洗涤室在物品(比如锅、平底锅、银餐具和其他烹饪器具)上循环。例如，流体可以是洗涤周期期间水和洗涤剂的各种组合，或者是漂洗周期期间的水(可以包括添加剂)。典型地，流体在给定的周期期间使用泵进行再循环。流体被收集在洗涤室的底部或底部附近，并通过例如喷射臂中的喷嘴和将流体引导朝向待清洗或漂洗的物品的其他开口泵回到室中。例如，在洗涤或漂洗周期中使用的流体可以被加热。例如，热水可以供应给洗碗机，或者洗碗机可以包括一个或更多个热源，用于加热在洗涤或漂洗周期中使用的流体，并且用于在干燥周期期间提供热量。
通常为洗碗机提供杆型的电阻加热元件，以便在一个或更多个洗碗机周期期间(例如，在干燥周期期间)在洗涤室内供应热量。一般来说，这些加热元件包括电阻型金属丝，该金属丝被包裹在氧化镁填充的金属护套中。不幸的是，这种加热元件通常对消费者来说是可见的，并且会产生不美观的外观。此外，任何暴露的元件都有可能钩住某些物体或无意中卡住掉落的器皿。
某些现代洗碗机试图利用具有热板加热器的杆型电阻加热元件来解决上述一些问题，该热板加热器通常仅提供基本上与桶的底部齐平的单个可见的表面。这种加热器能够在洗涤桶内随着水经过可见的表面时加热这些水。然而，在干 燥周期或没有水流过可见的表面的周期中，这种加热器的使用通常是不可能的。这通常至少部分是由于热板加热器处的热量的高度集中和热量产生，如果没有水从加热器吸取热量(即冷却)的话，这有损坏洗碗机的周围部分的风险。
因此，提供一种能够解决一个或更多个上述问题的洗碗器具或方法可能是有用的。特别地，具有用于加热洗涤室，特别是在干燥周期期间，而没有损坏器具的风险、弄乱洗涤室或降低器具的整体尺寸/复杂性要求的洗碗器具或方法将是有利的。

具体实施方式
现在将详细参考本发明的实施例，其一个或更多个示例在附图中示出。每个示例都是通过解释本发明的方式提供的，而不是对本发明的限制。事实上， 对于本领域的技术人员来说显而易见的是，在不脱离本发明的范围的情况下，可以对本发明进行各种修改和变化。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修改和变化。
如本文所用，术语“或”通常旨在是包含性的(即，“A或B”旨在指“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部件区分开来，并且不旨在表示各个部件的位置或重要性。术语“物品”可以指但不限于碗碟、锅、平底锅、银餐具和其他可以在洗碗器具中清洗的烹饪器皿和物体。术语“洗涤周期”旨在指清洁过程期间的一个或更多个时间段，在该时间段洗碗器具在容纳待洗涤物品的同时运行，并使用水或洗涤剂来例如从物品中去除污垢颗粒(包括食物和其他不希望的元素)。
图1和图2描绘了可以根据本公开的方面构造的示例性家用洗碗机100。如图所示，洗碗机100包括其中安装有桶104的机壳102(即，桶在机壳102的内部112内)。如图所示，桶104限定了洗涤室106。在一些实施例中，桶104包括至少部分限定洗涤室106的多个侧壁128(例如，在顶部壁114和底部壁116之间)。桶104进一步包括前开口和铰接在其底部122的门118，用于在关闭(例如，竖直)位置(如图1和图2所示)和打开(例如，完全或部分打开)位置之间移动，在关闭位置，洗涤室106被密封封闭，用于洗涤操作或洗涤周期，在打开位置，用于从洗碗机100装载和卸载物品。因此，通常在关闭位置限制对洗涤室106的进入，而在打开位置允许对清洗室106进入。在一些实施例中，闩锁123用于锁定和解锁门118以进入室106。门118包括内壁120。当门118处于关闭位置时，内壁120进一步限定洗涤室106。
上部导向轨道和下部导向轨道124、126安装在桶侧壁128上，并容纳配备有滚轮的支架组件130和132。每个支架组件130、132都被制造成包括多个细长构件134的网格结构(为了清楚起见，图2中未示出构成组件130和132的所有细长构件)。每个支架组件130、132布置在洗涤室106中，使得支架组件 130、132能够在延伸的装载位置(未示出)和缩回位置(如图1和图2所示)之间移动，在延伸的装载位置，支架基本上位于洗涤室106的外部，在缩回位置，支架位于洗涤室106的内部。例如，这通过分别安装在支架组件130和132上的滚轮135和139来实现。银餐具篮(未示出)可以可移除地附接到支架组件132，用于放置银餐具、器皿等，否则这些银餐具、器皿等太小而不能被支架组件130、132容纳。
在一些实施例中，洗碗机100进一步包括下部喷射臂组件144，其可旋转地安装在洗涤室106的下部区域146内，并且在集液槽142上方，以便相对紧密地靠近支架组件132而旋转。在一些实施例中，中层的喷射臂组件148位于洗涤室106的上部区域，并且可以被定位成紧密靠近上部支架130。附加地或替代地，上部喷射组件150可以位于上部支架130上方。
热板加热器170可用于在例如洗涤、漂洗或干燥周期期间提供热量。如下文将详细描述的，加热器170通常包括安装在洗涤室106外部的电阻加热元件222和具有室表面214的传导体210，室表面布置在洗涤室106内。通常，电阻加热元件222可以被提供为任何合适的电驱动的加热元件(例如，带护套的加热元件；镍铬合金丝、钨丝；管状棒加热器——比如那些在
Figure PCTCN2021115872-appb-000001
商标下销售的加热器；等)。当启动时，电阻加热元件222处产生的热量因此可以通过传导体210转移(例如传导)并转移到洗涤室106。
在一些实施例中，空气处理器或风扇180设置成与热板加热器170流体连通。具体而言，并且也将在下面详细描述，风扇180可以安装在机壳102内并且在桶104或洗涤室106的外部。因此，风扇180可被选择性地启动以推动气流穿过热板加热器170的至少一部分(例如，电阻加热元件222)。
如所理解的，每个喷射臂组件144、148包括排放端口或孔口的布置，用于将流体引导到位于支架组件130和132中的碗碟或其他物品上。喷射臂组件144、148中的排放端口的布置借助于流动通过排放端口的洗涤流体提供旋转力。喷射臂组件144、148的所得到的旋转和喷射组件150的操作提供了用洗涤喷射对碗 碟和其他洗碗机内容物的覆盖。也可以使用喷射组件的其他构造。
下部喷射臂组件和中层的喷射臂组件144、148和上部喷射组件150可以作为流体循环组件152的一部分提供，用于使水和洗碗机流体在桶104中循环。在一些实施例中，流体循环组件152包括循环导管154，其将流体供应到下部喷射臂组件和中层的喷射臂组件144、148或上部喷射组件150。导管154可以例如与集液槽142(例如，由底部壁116限定)流体连通，使得流体可以根据需要从集液槽142流动到导管154中。
如上所述，洗碗机组件100进一步包括集液槽142(例如，由桶104限定，比如由底部壁116限定)，集液槽可以设置在例如下部喷射臂组件144下面的下部区域146中。集液槽142通常收集来自洗涤室106的流体，用于在桶104内循环(比如通过流体循环组件152返回到洗涤室106中)，并且通常用于从桶104和洗碗器具100排出。例如，可以通过排出导管158进行排出，该排出导管被设置成用于从集液槽142中排出流体。导管158可以例如与集液槽142流体连通，使得流体可以根据需要从集液槽142流动到导管158中。排出导管158可以使流体从集液槽142流动到例如外部管道或其他合适的排出位置。
如图所示，洗碗机100进一步配备有控制器137，以调节洗碗机100的操作。控制器可以包括一个或更多个存储器设备和一个或更多个微处理器，比如通用或专用微处理器，其可操作来执行与洗涤周期相关联的编程指令或微控制代码。存储器可以代表随机存取存储器(比如DRAM)，或者只读存储器(比如ROM或FLASH)。在一些实施例中，处理器执行存储在存储器中的编程指令。对于某些实施例，指令包括被配置成操作器具100的软件包。存储器可以是与处理器分离的部件，或者可以板载地包含在处理器内。
控制器137可以位于整个洗碗机100的多个位置。例如，控制器137可以位于门118的控制面板区域121内，如图1和图2所示。在这样的实施例中，输入/输出(“I/O”)信号可以沿着线束在控制系统和洗碗机100的各种操作部件之间传送，所述线束可以穿过门118的底部122布线。典型地，控制器137包 括用户界面面板或控制器136，用户可以通过该用户界面面板或控制器选择各种操作特征和模式，并监控洗碗机100的进度。在一个实施例中，用户界面136可以代表通用I/O(“GPIO”)设备或功能块。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、机械或机电输入设备(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，例如被设计成为向用户提供操作反馈的数字或模拟显示设备。用户界面136可以经由一条或更多条信号线或共享通信总线与控制器137通信。
在一些实施例中，控制器137经由一条或更多条信号线或共享通信总线与加热器170或风扇180通信。此外，控制器137通常被配置成根据一个或更多个检测到的或预定的条件选择性地启动加热器170或风扇180。例如，控制器137可以被配置成开始洗涤操作，该洗涤操作包括在一个或更多个周期(例如，洗涤周期、漂洗周期或干燥周期)期间启动加热器170或风扇180。可选地，控制器137可以被配置成选择性地改变加热器170的瓦特数。例如，控制器137可以被配置成开始对加热器170的电功率的调节(例如，根据正在执行的周期)。
应当理解，本发明不限于洗碗机的任何特定样式、型号或构造。图1和图2所描绘的示例性实施例仅用于说明目的。例如，可以为用户界面136提供不同的位置，可以为支架130、132提供不同的构造，并且也可以应用其他差异。
现在转向图3至图6，提供了桶104的底部部分的各种视图，包括底部壁116、加热器170和风扇180。如上所述，热板加热器170通常设置成与洗涤室106热连通。特别地，传导体210的室表面214可以由设置在洗涤室106内的上部板212限定，以将热量传导至洗涤室106。与室表面214相反，上部板212可以限定被定向成远离洗涤室106的内表面216(例如，朝向机壳102的在桶104下方的内部112)。热板加热器170因此可操作以引导热量通过传导体210(例如，从内表面216到室表面214)来加热洗涤室106(即，加热洗涤室106内的空气或水)。
在某些实施例中，热板加热器170被安装成穿过桶104的壁中的一个或安 装至桶的壁中的一个。在图3至图6的示例性实施例中，热板加热器170安装至底部壁116。例如，底部壁116可以限定孔，传导体210的至少一部分保持在孔中。在一些这样的实施例中，孔被限定成沿着横向方向T靠近后端部110而远离前端部108。换句话说，与孔对于前端部108相比，孔可以更接近后端部110。因此，热板加热器170可以被安装成靠近后端部110且远离前端部108。有利地，热板加热器170可以与前开口隔开地设置，从而避免用户接触或可能暴露于热板加热器170。
如图所示，传导体210可以包括从上部板212延伸(例如，沿着竖直方向V向下)的周边边缘218。周边边缘218可以是分立的附接元件，或者替代地，是与上部板212一体的整体单元。在一些实施例中，周边边缘218延伸穿过桶104。例如，周边边缘218可以延伸穿过由底部壁116限定的孔。可选地，周边边缘218可以接合到单独的托架或直接接合到桶104(例如，经由合适的机械紧固件、粘合剂等)。
当组装时，传导体210可限定凹穴220，其向内部112的在洗涤室106外(例如，桶104下方)的一部分敞开。具体地，凹穴220可以被限定为被部分包围的区域。有利的是，空气和热量可以在凹穴220和内部112之间传递。在一些实施例中，周边边缘218和上部板212限定了凹穴220。换句话说，周边边缘218和上部板212可以限定凹穴220的边界。例如，内表面216可以限定凹穴220的上部边界，而周边边缘218可以限定凹穴220的水平边界。凹穴220的开口可以限定在周边边缘218的与上部板212相反的端部。
一个或更多个电阻加热元件222可以设置成与传导体210热连通(例如对流或传导热连通)。具体而言，一个或更多个电阻加热元件222安装在洗涤室106的外部，并且邻近或靠近内表面216。因此，至少一个电阻加热元件222在内表面216处与传导体210热连通。电阻加热元件222可以与传导体210接触，或者，替代地，与传导体210间隔开。可以防止洗涤室106内的水流动到电阻加热元件222或接触电阻加热元件。例如，传导体210可以阻止洗涤室106内的 水流流动到电阻加热元件222。在一些实施例中，电阻加热元件222设置在室表面214下方(例如，在上部板212的正下面)。可选地，电阻加热元件222可以安装在低于上部板212和底部壁116的至少一部分的位置。在附加的或替代的实施例中，电阻加热元件222被接收在凹穴220内。在使用期间(例如，当电阻加热元件222被启动时)，电阻加热元件222处产生的热量可以被引导到内表面216(例如，经由传导或自然热对流)。
简要地转向图7和图8，热板加热器170的示例性实施例的示意图。在一些实施例中，一个或更多个电阻加热元件222可以作为可变瓦特数的加热电路223提供。
作为示例，多个单瓦特数的加热元件(例如，用于洗涤或漂洗周期的高瓦特数的湿周期元件222A和用于干燥周期的低瓦特数的干燥周期元件222B)可以设置在可变瓦特数的加热电路223内，可变瓦特数的加热电路可以被配置为选择性地使功率或瓦特数在多个单瓦特数的加热元件222A、222B之间交替。电压源224和一个或更多个开关元件226(例如，双掷开关、转换开关等)可以电联接到多个单瓦特数的加热元件222A、222B，作为可变瓦特数的加热电路223的一部分。控制器137可以可操作地连接到开关元件226。通过选择性地切换或改变开关元件226的位置来改变多个单瓦特数的加热元件中的哪一个从电压源224接收电压(例如，A/C电压)，可以改变功率或瓦特数。
作为附加的或替代的示例，特定的加热元件222C可以设置在可变瓦特数的加热电路223内，其可以被配置成选择性地改变该特定的加热元件222C的功率或瓦特数。电压源224和一个或更多个开关元件226(例如继电器、晶闸管等)可以电联接到特定的加热元件222C，作为可变瓦特数的加热电路223的一部分。控制器137可以可操作地连接到开关元件226。可选地，比如，对于继电器，通过选择性地启动开关元件226以使来自电压源224的A/C电压循环，可以改变加热元件222C的功率或瓦特数。加热元件222C的电压因此可以根据开关元件226的状态快速地周期性断开和接通。加热元件222C的连续(即，非周期性) 操作通常对应于加热元件222C的较高瓦特数的输出(与周期性操作相比，在周期性操作中，加热元件222C的功率受到限制)。因为加热元件222C的功率或瓦特数被改变，所以可以由此调节加热元件222C的瓦特数输出。附加地或替代地，比如，对于晶闸管或TRIAC，加热元件222C的功率或瓦特数可以按照来自电压源的设定瓦特数的百分比直接变化。
如图所示，风扇180被保持在或以其他方式安装机壳102的在洗涤室106外的一部分内(例如，在内部112内)。风扇180可以设置为任何合适的风扇、空气处理器或鼓风机；比如轴流式风扇或离心式风扇。当组装时，风扇180定位成与热板加热器170的至少一部分流体连通，以推动气流(例如，冷却气流230)穿过电阻加热元件222(例如，当风扇180旋转或以其他方式启动时)。例如，风扇180可以安装在热板加热器170的上游或替代地下游。由风扇180推动的气流(例如，冷却气流230)可以有利地加速电阻加热元件222和周围空气之间的热交换，使得电阻加热元件222被冷却并且被推动的气流被加热，比如在干燥周期期间。
在示例性实施例中，风扇180安装或设置在热板加热器170下方。例如，风扇180可以设置在热板加热器170的正下方(例如，在下方竖直对齐)，或者替代地，在沿着竖直方向V的较低的位置处从热板加热器170水平偏移。此外，风扇180可以设置在电阻加热元件222或凹穴220的下方(例如，以推动气流穿过或通过电阻加热元件或凹穴)。
气流路径234被限定在机壳102内，以引导由风扇180推动的气流(例如，冷却气流230)或为由风扇推动的气流导向。具体而言，气流路径234在机壳102内从入口236延伸到出口238。入口236通常设置在洗涤室106的外部(例如，内部112内，在风扇180的上游或替代地在风扇的下游)，以接收来自内部112或周围环境的空气(例如，作为冷却气流230的一部分)。出口238通常设置在入口236和风扇180的下游。此外，出口238设置在洗涤室106的上游。例如，出口238可以被限定为穿过桶104(例如，穿过侧壁128)。在使用期间， 由风扇180推动的气流230可以经过电阻加热元件222并穿过入口236，沿着气流路径234，并通过出口238离开到洗涤室106中。
如图所示，气流路径234可以由保持在机壳102内的导管240限定。进而，气流路径234可以与内部112的其余部分分开地限定。导管240因此可以从入口236延伸到出口238。在某些实施例中，入口236设置在热板加热器170下方(例如，底部壁116下方)，而出口238设置在热板加热器170上方(例如，穿过侧壁128)。可选地，风扇180可以安装至导管240，比如安装在入口236下游和出口238上游的位置。
在一些实施例中，控制器137与热板加热器170和风扇180在操作上通信(即，在操作上联接到两者)，以协调两者的启动(例如，基于正在执行的周期)。
作为示例，控制器137可以被配置成开始干燥周期(例如，作为洗涤操作的一部分，在洗涤或漂洗周期之后)，其中热板加热器170和风扇180被启动，这在图6中特别示出。干燥周期可以包括停止通过洗涤室106的水流(例如，使得防止水源向洗涤室106添加水)。可以防止循环泵将水泵送到洗涤室或通过洗涤室106。尽管如此，干燥周期可以包括打开排出导管158(图2)或启动排出泵将水泵送出洗涤室106。在停止水流之后或与之同时，干燥周期可以包括启动电阻加热元件222。具体而言，电压可被引导至电阻加热元件222，产生将被周围空气(例如，在凹穴220或内部112内)吸收的热量。在包括可变瓦特数的加热组件224的实施例中，电阻加热元件222可以根据相对低的瓦特数来启动(例如，低瓦特数的加热元件可以被启动或者可变瓦特数的加热元件可以在大于0的低瓦特数输出下被启动)。当电阻加热元件222启动时(例如，在电阻加热元件222开始启动之前、同时或之后开始)，气流可以在风扇180处被推动。换句话说，风扇180可以旋转或以其他方式启动，以推动冷却气流230穿过热板加热器170的至少一部分(例如，如上所述)。
作为附加的或替代的示例，控制器137可以被配置成开始湿周期(例如，作为洗涤操作的一部分并且与干燥周期分开的洗涤周期或漂洗周期)，其中热板 加热器170和风扇180被启动，这在图5中被特别示出。湿周期可以包括使水流循环通过洗涤室106。例如，循环泵可以被启动以将水泵送到或通过洗涤室106(例如，从导管154，图2)。附加地或替代地，可以打开水源下游的阀，以允许水从洗碗机100的外部流动到洗涤室106，如所理解的。当水在循环时，湿周期可以包括启动电阻加热元件222。具体而言，电压可被引导至电阻加热元件222，产生热量，该热量将在传导体210处被接收并被流动穿过传导体210(例如，在洗涤室106内)的水吸收。在包括可变瓦特数的加热组件224的实施例中，电阻加热元件222可以根据相对高的瓦特数来启动(例如，高瓦特数的加热元件可以被启动，或者可变瓦特数的加热元件可以在比低瓦特数输出更高的瓦特数输出下被启动)。当电阻加热元件222启动时(例如，在电阻加热元件222开始启动之前、同时、之后开始)，风扇180处的气流(例如，冷却气流230，图6)可以停止。例如，风扇180可以保持在非启动状态，从而防止推动气流穿过热板加热器170。进而，在热板加热器170处产生的热量可以被集中到洗涤室106。
有利的是，上面描述的实施例可以允许启动热板加热器170，用于在干燥周期期间加热空气，而不需要洗涤室106内的加热元件。附加地或替代地，可以防止热板加热器170过热(例如，在干燥周期期间)。
该书面描述使用示例来公开本发明，包括最佳模式，并且还使本领域的任何技术人员能够实践本发明，包括制造和使用任何设备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，并且可以包括本领域技术人员想到的其他示例。如果这样的其他示例包括与权利要求的字面语言没有不同的结构要素，或者如果它们包括与权利要求的字面语言没有实质差异的等同结构要素，则这些其他示例旨在在权利要求的范围内。
