Description

具有轴承系统的感应干燥器设备 技术领域
本主题总体上涉及感应干燥器设备。
背景技术
干燥器设备通常包括机壳，其具有可旋转地安装在其中的滚筒。在操作期间，马达使滚筒旋转，例如，以使位于滚筒中的腔室内的物品翻滚。干燥器设备通常还包括加热器组件，其传递加热的空气通过腔室，以便干燥滚筒腔室中的带水分的物品。通常，空气处理器用于推动加热的空气从腔室流动通过捕获管道并至排出管道，加热的空气在排出管道处从干燥器设备中排出。干燥器设备可以进一步包括过滤器系统，其用于移除外来材料(比如，绒毛)以免进入到排出导管中，外来材料可能损害干燥器性能并由于存在燃烧的可能性而可能存在危险。
传统的加热器组件包括电力电阻加热器，比如导线线圈，当电流通过它们时会产生热量。值得注意的是，这些电阻加热器通常仅70％-80％的效率，从而导致在操作期间显著的浪费的能量。另外，已知的干燥器设备包括两个电阻加热器线圈，其连接到三相电源系统，以在三个步骤中的一个中为这些加热器供能，所述三个步骤，即，无热量的关闭(OFF)、低热量的一个加热器开启(ON)、或者高热量的两个加热器开启(ON)。因此，滚筒内的温度可能不是被线性地控制的，从而导致在使用不同操作循环以干燥各种负载类型方面上的受限制的通用性和显著的操作约束。

在第二示例性实施例中，感应干燥器设备包括机壳。滚筒定位在机壳内。滚筒可在机壳内绕轴线旋转。感应干燥器设备还包括一对感应加热元件。一对支撑组件邻近滚筒定位在机壳内。所述对支撑组件中的每个支撑组件包括板和轴承。所述对感应加热元件中的每个感应加热元件定位在所述对支撑组件的相应的板上。每个轴承安装到所述对支撑组件的相应的板上。当滚筒绕轴线旋转时，每个轴承接触滚筒，以便沿着垂直于轴线的径向方向将相应的板与滚筒间隔开。
参考以下描述和所附权利要求，将更好地理解本发明的这些和其它特征、方面和优点。包含在本说明书中并构成本说明书的一部分的附图示出了本发明的实施例，并与说明书一起用于说明本发明的原理。

图2是图1的示例性干燥器设备的滚筒和感应加热器的前截面图。
图3是图1的示例性干燥器设备的滚筒和感应加热器的侧视截面图。

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。实际上，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这些修改和变化。
图1示出了根据本主题的示例性实施例的干燥器设备10。图2和3是干燥器设备10的各个部件的示意图。尽管在干燥器设备10的特定实施例的上下文中进行了描述，但是通过使用本公开的教导，应该理解的是，干燥器设备10仅以示例的方式提供。具有不同外观和不同特征的其它干燥器设备也可以与本主题一起使用。
参考图1至3，干燥器设备10包括具有门14的机壳12。容器或滚筒16位于机壳12内，所述容器或滚筒限定了用于接收用于干燥的物品(例如，衣物、亚麻制品等)的腔室18。滚筒16可在机壳12内例如绕轴线X旋转。特别地，马达24联接至滚筒16，使得马达24可操作为使滚筒16绕轴线X旋转。带26可以将马达24联接至滚筒16，使得马达24可操作为使滚筒16旋转。门14可旋转地安装到机壳12上，以提供对滚筒16的选择性进口。
空气处理器20(比如，鼓风机或风扇)可以设置为产生通过腔室18的空气流。因此，空气处理器20被构造成用于抽吸空气流动通过滚筒16的腔室18，例如，以便干燥位于其中的物品。干燥器设备10可以包括用于加热腔室18内的空气和/或物品的感应加热元件22，如以下更详细地讨论的。热量有助于干燥布置在滚筒16的腔室18内的潮湿物品。
如上所述，在干燥器设备10的操作期间，马达24操作为经由带26旋转滚筒16。此外，空气处理器20操作为产生通过滚筒16的腔室18的空气流。特别地，空气处理器20可以迫使环境空气进入到滚筒16的腔室18中。在腔室18内，环境空气被感应加热元件22加热，并且加热的空气例如从布置在腔室18内的潮湿物品中移除湿气。然后，带水分的加热的空气从腔室18流动并从机壳12排出。包括筛网过滤器或用于移除绒毛和其它颗粒的其它合适的装置的过滤 器(未示出)可以设置为过滤离开腔室18的带水分的加热的空气。在衣物物品已经被干燥(或者以其它方式完成干燥循环)之后，例如通过打开门14进入腔室18将衣物物品从滚筒16中移除。
一个或更多个选择器输入件30，比如旋钮、按钮、触摸屏接口等，可以设置在机壳12的控制面板32上，并可以与处理装置或控制器34通信。响应于选择器输入件30的致动，通过在控制器34中产生的信号操作空气处理器20、感应加热元件22、马达24和其它干燥器设备部件。另外，显示器36(比如，指示灯或屏幕)可以设置在控制面板32上。显示器36可以与控制器34通信，并且可以响应于来自控制器34的信号显示信息。
如本文所使用的，“处理装置”或“控制器”可以指一个或更多个微处理器或半导体装置，并且不必限于单个元件。处理装置可以被编程为操作干燥器设备10。处理装置可以包括一个或更多个存储器元件(例如，非暂时性存储介质)或与一个或更多个存储器元件相关联。在一些这样的实施例中，存储器元件包括电可擦除可编程只读存储器(EEPROM)。通常，存储器元件可以储存处理装置可访问的信息，包括可以由处理装置执行的指令。可选地，指令可以为软件或在由处理装置执行时导致处理装置执行操作的指令和/或数据的任何集合。对于某些实施例，指令包括被设置为操作设备10并执行某些循环或操作模式的软件包。
感应加热元件22通常包括邻近滚筒16定位的感应线圈，比如绞合导线线圈。感应线圈通常被构造成在被供应以高频交变电流时产生电磁场。此外，滚筒16由铁磁材料构成或构成有铁磁材料，比如铁、铁合金或存在电磁场的情况下产生热量的任何其它合适的材料。因此，滚筒16(或滚筒16的部件)被构造成在由来自感应线圈的电磁场供能时通过在滚筒16中感应出涡电流而产生热量。
控制器34可以可操作地联接到感应加热元件22的感应线圈，并且可以被构造成在特定干燥器操作循环内根据需要为感应线圈供能。在这方面，例如， 控制器34可以被构造成渐进地或线性地调节由感应线圈产生的电磁场，从而能够微调由感应加热元件22产生的热量及对应的滚筒温度。相反，传统的电阻加热器仅具有一个或两个加热级别。
图4是干燥器设备10的支撑组件100的局部截面图。支撑组件100被构造成用于将一个或更多个感应加热元件22定位成邻近滚筒16。在图4中，感应加热元件22中的仅一个被定位在支撑组件100上。因此，支撑组件100在下文中在支撑感应加热元件22中的一个的上下文中被更详细地描述。感应加热元件22中的其它感应加热元件可以定位在、例如在滚筒16的相对端部处的附加支撑组件上。附加支撑组件可以以与图4所示的方式相同或类似的方式构造。在替代示例性实施例中，支撑组件100可以被构造成支撑两个感应加热元件22。
支撑组件100可以定位在机壳12内。特别地，支撑组件100可以直接定位在机壳12内的滚筒16下方。如下文更详细地讨论的，支撑组件100包括用于维持感应加热元件22和滚筒16之间的径向间隙G的特征。因此，支撑组件100可以助于通过感应加热元件22对滚筒16更加恒定地加热。
支撑组件100包括板110和一对轴承120。感应加热元件22定位在板110上。例如，感应加热元件22可以例如通过紧固件、夹具等安装到板110上。作为示例，板110可以由模制塑料形成。轴承120安装到板110上并与滚筒16接触。特别地，当滚筒16绕轴线X旋转时，轴承120接触滚筒16。因此，轴承120沿着例如垂直于轴线X的径向方向R将板110与滚筒16间隔开。
当滚筒16绕轴线X旋转时，轴承120可以将板110与滚筒16间隔开，以便维持恒定的径向间隙G。换句话说，轴承120允许感应加热元件22跟踪滚筒16的沿着径向方向R的运动。与相对于机壳12固定感应加热元件22相比，通过恒定的径向间隙G，干燥器设备10的性能可以被改善。特别地，通过轴承120维持恒定的径向间隙G可以允许利用感应加热元件22对滚筒16进行更加精确和/或准确的加热。径向间隙G可以限定在滚筒16的外表面与感应加热元件22的外表面之间，滚筒16的外表面与感应加热元件22的外表面沿着径向方向R 彼此面向。
轴承120还可以在板110上沿着例如平行于轴线X的轴向方向A间隔开。特别地，感应加热元件22可以沿着轴向方向A在板110上定位在轴承120之间。轴承120之间的这种间隔和/或感应加热元件22与轴承120的相对位置可以助于相对于滚筒16可靠地定位感应加热元件22。特别地，轴承120之间的这种间隔可以限制感应加热元件22在板110上相对于滚筒16的旋转。
轴承120可以是滚子轴承、滑动轴承等。当轴承120是滚子轴承时，轴承120可以在滚筒16的外表面上滚动。因此，轴承120可以助于维持恒定的径向间隙G，而不会显著地增加通过马达24来旋转滚筒所需的能量。
支撑组件100还可以包括一对弹簧130。弹簧130联接至板110。弹簧130例如沿着径向方向R朝向滚筒16推动板110。弹簧130可以朝向滚筒16推动板110，使得当滚筒16绕轴线X旋转时，轴承120维持与滚筒16接触。例如，由弹簧130施加的力可以取向为朝向轴线X和/或落到轴线X上。弹簧130可以是螺旋弹簧、气弹簧等。弹簧130可以在机壳12的底板上的基座102与滚筒16下方的板110之间延伸。
如从上文可以看到的，板110和感应加热元件22可以朝向滚筒16偏置。因此，弹簧130可以助于维持感应加热元件22与滚筒16之间的恒定的径向间隙G。弹簧130可以沿着轴向方向A间隔开。例如，每个弹簧130可以邻近轴承120中的相应一个定位。
在图4中，感应加热元件22在板110上定位在滚筒16下方。如上所述，图4中仅示出了感应加热元件22中的一个。感应加热元件22中的其它感应加热元件可以在带26的相对侧上定位在滚筒12上。因此，带26可以沿着轴向方向A定位在感应加热元件22之间。
本书面描述使用示例来公开本发明，包括最佳模式，并且允许本领域任何技术人员实践本发明，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，并且可以包括本领域技术人员想到的 其它示例。如果这样的其它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，则这些其它示例意图在权利要求的范围内。
