Description

带有添加剂分配器的干燥机设备 技术领域
本主题总体上涉及干燥机设备，更具体地说，涉及利用贮存器和泵向干燥机设备内的负载提供添加剂的干燥机设备。
背景技术
用于干燥物品(例如衣服物品)的传统设备，比如衣物干燥机(或洗衣干燥机)，通常包括具有旋转滚筒的机壳，用于在其中翻滚衣物和洗衣物品。一个或更多个加热元件在空气进入滚筒之前加热空气，并且暖空气随着衣物翻滚而循环通过滚筒，以从滚筒中的洗衣物品中去除湿气。气体或电加热元件可以用于加热循环通过滚筒的空气。
在操作中，来自外部的环境空气被抽吸到机壳中，并在被送入滚筒之前经过加热器。衣服中的湿气被转移到经过滚筒的空气中。典型地，这种充满湿气的空气然后通过例如通向放置干燥机的结构或房间外部的管道被输送离开干燥机。排出的空气从干燥机中去除湿气，并且随着该过程的继续，通过抽吸更多的环境空气来干燥衣物。
在某些情况下，可能希望向滚筒内的衣物提供一种或更多种添加剂，例如，可以提供添加剂以减少皱褶，改善衣物的气味，和/或可以提供其他织物处理添加剂，比如织物柔顺剂。例如，用户可能喜欢更香的衣物，或者洗衣可能已经在干燥腔室中放置了很长一段时间，并且可能闻起来有点变味或发霉。提供添加剂的常规方法包括：在启动干燥机之前，将干燥片或其它添加剂手动地放置在干燥腔室内。替代地，衣物可能会再次洗涤和干燥，导致过度消耗能量和水。
因此，具有用于储存添加剂和选择性地向滚筒内部提供添加剂的改进特征的干燥机设备将是有利的。

具体实施方式
现在将详细地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，对于本领域技术人员来说清楚明白的是，在不脱离本发明的范围或精神的情况下，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这种修改和变化。
如本文所使用的，近似术语，比如“基本上”、“大致”或“大约”，包括比所述的值大或小百分之十以内的值。当在角度或方向的上下文中使用时，这些术语包括比所述的角度或方向大或小十度以内的角度或方向。例如，“大致竖直”包括在任何方向上(例如顺时针或逆时针)竖直十度以内的方向。
现在转向附图，图1提供了根据本公开的示例性实施例的干燥机设备10的透视图。图2提供了干燥机设备10的剖视图。干燥机设备10通常限定竖直方向V、侧向方向L和横向方向T，每个方向相互垂直，从而限定正交坐标系。虽然使用本文公开的教导在干燥机设备10的特定实施例的上下文中进行了描述， 但是应当理解，干燥机设备10仅通过示例的方式提供。具有不同外观和不同特征的其他干燥机设备也可以采用本主题。
机壳12包括前面板14、后面板16、由前面板14和后面板16彼此间隔开的左侧面板18和右侧面板20、底面板22和顶盖24。如本文所使用的，术语，比如“左”和“右”或“前”和“后”指的是从面向干燥机设备10的用户的角度来看用于接近和/或操作干燥机设备10的方向。例如，用户站在干燥机设备10的前面，例如，在前面板14处或附近，以接近门33和/或输入70(门33和输入70将在下面更详细地描述)。在机壳12内，限定了内部容积29。滚筒或容器26安装成在内部容积29内绕大致水平轴线旋转。滚筒26限定了用于接收衣服物品以进行翻滚和/或干燥的腔室25。滚筒26在前部部分37与后部部分38之间延伸。供应管道41可以安装至滚筒26，并接收已被加热组件或系统40加热的加热空气。
如本文所使用的，术语“衣服”或“衣物”包括但不限于织物、纺织品、服装、亚麻制品、纸制品或希望从中提取湿气的其它物品。此外，术语“负载”或“洗衣负载”指的是可以在洗衣机中一起洗涤或在干燥机设备10(例如，衣物干燥机)中一起干燥的衣服的组合，并且可以包括在特定的洗衣过程中不同或相似类型和种类的织物、纺织品、服装和亚麻制品的不同或相似衣服物品的混合物。
在一些实施例中，可以提供马达(未示出)，以使滚筒26绕水平轴线旋转。滚筒26的形状通常为柱形，具有外柱形壁28和前凸缘或壁30，该前凸缘或壁限定了滚筒26的开口32，例如在滚筒26的前部部分37处，用于将物品装载到滚筒26的腔室25中和从其中卸载物品。多个抬升件或挡板(未示出)可以设置在滚筒26的腔室25内，以抬升其中的物品，然后允许这些物品随着滚筒26旋转而翻滚回滚筒26的底部。这种挡板可以安装至滚筒26，使得在干燥机设备10的操作期间挡板与滚筒26一起旋转。
滚筒26包括后壁34，该后壁通过合适的固定支承件被可旋转地支撑在主壳 体12内。后壁34可以是固定的或者是可旋转的。后壁34可以包括例如多个孔，这些孔接收已经被加热系统40加热的热空气，加热系统可以包括例如电阻加热元件、气体燃烧器和/或加热泵。充满湿气的加热空气被空气处理器(比如鼓风机风扇)从滚筒26中抽吸，这在滚筒内产生负空气压力。空气经过封闭筛网过滤器的管道，筛网过滤器捕集绒毛颗粒。当空气从鼓风机风扇经过时，空气进入管道，然后进入到加热系统40中。加热空气(具有比从滚筒26接收的空气更低的湿气含量)离开加热系统40，并通过管道41返回滚筒26。在衣服物品被干燥后，它们经由开口32从滚筒26中移除。提供门33用于通过开口32关闭或进入滚筒26。窗口36(图1)可以设置在门33中，用于例如在干燥机设备10操作期间观察滚筒26的腔室25和/或其中的洗衣物品。
在一些实施例中，一个或更多个选择器输入70(比如旋钮、按钮、触摸屏界面等)可以设置或安装在机壳12上，例如在其控制面板71上，并且与处理装置或控制器56可操作地通信(例如，电联接或通过无线网络带联接)。控制面板71还可以包括显示器64。控制器56还可以设置成与干燥机设备的各种部件(比如马达、鼓风机和/或加热系统40)可操作地通信。进而，控制器56中生成的信号响应于输入70的位置来指导这些部件的操作。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、微控制器、ASICS或半导体装置，并且不一定限于单个元件。控制器56可以被编程为通过执行存储在存储器(例如，非暂时性介质)中的指令来操作干燥机设备10。控制器56可以包括一个或更多个存储器元件(比如RAM、ROM或电可擦除可编程的只读存储器(EEPROM))或与一个或更多个存储元件相关联。例如，指令可以是软件或任何指令集，当由处理装置执行时，这些指令使得处理装置执行操作。
现在参考图3至图7，根据本主题的示例性实施例，将描述用于将添加剂1000引入干燥腔室25中(从而引入到在其中干燥的衣物2000中)的系统。如图所示，例如在图1至图4中，在一些示例性实施例中，干燥机设备10可以包括安装在机壳12中的贮存器152。贮存器152可以被配置为容纳添加剂1000(比 如液体添加剂)，并且可以与腔室25流体连通，例如流体地连接到腔室。例如，贮存器152可以与一个或更多个喷洒喷嘴146(图4)流体连通，所述喷洒喷嘴定位和布置成提供从贮存器152到腔室25中的添加剂的喷洒，比如喷洒到其中的衣服物品2000上。贮存器152可以有利地从干燥机设备10的前部可见并可接近(例如，如图1所示)。
如图3和图4所示，贮存器152可以经由一个或更多个喷洒喷嘴146(图4)与腔室25流体连通。例如，如图3和图4所示，贮存器152可以通过第一导管140连接到泵142。泵142可以通过第二导管150连接到喷洒喷嘴146。在一些实施例中，泵142可以安装到贮存器152，并且第二导管150可以在其中包括可拆卸联接151，以适应贮存器152和泵142相对于机壳12的移动，例如，当贮存器152以及在这样的实施例中安装到其上的泵142被从机壳12移除时，可拆卸联接151允许第二导管150的直接附接到泵142的第一部分从机壳12移除，而第二导管150的直接附接到喷洒喷嘴146的第二部分保留在机壳12中。当贮存器152重新插入到机壳12中时，可拆卸联接151被重新连接，以完成从泵142经由第二导管150到喷洒喷嘴146的连接。
因此，如将理解的，泵142可以操作以从贮存器152抽吸流体(例如液体添加剂)，并将流体从泵142通过第二导管150向喷洒喷嘴146推动。在图4中可见，喷洒喷嘴146可以定位在滚筒26的开口32附近，并定向成将添加剂1000的喷洒引导到滚筒26的腔室25中。例如，喷洒喷嘴146可以包括孔口148(图4)，该孔口定向成远离开口32并进入或朝向腔室25。如将理解的，由泵142提供给添加剂的压力和孔口148的小尺寸(例如，与喷洒喷嘴146上游的导管140和150相比，孔口的直径和/或横截面面积可以相对较小)提供了从喷洒喷嘴146到腔室25中的添加剂的喷洒。
图5提供了根据本公开的一个或更多个示例性实施例的贮存器152的透视图。如图5所示，贮存器152可以包括面板154。例如，贮存器152可以从机壳12移除，例如，贮存器152可以可移除地安装在机壳12中，以便例如经由入口 158用添加剂1000填充贮存器152，如图5中的箭头1000所示。当贮存器152处于机壳12内的关闭或安装位置时，例如，如图1和图2所示，贮存器152的面板154可以与机壳12的前面板14和/或控制面板71大致齐平，例如，沿着横向方向T(图1和图2)偏移不超过面板154的厚度的百分之十。贮存器152可以进一步包括主体156，在该主体内限定贮存器152的内部容积。入口158可以设置在主体156中，并且可以限定延伸通过主体156(例如，从主体的外部延伸到贮存器152的主体中的内部容积中)的开口160。因此，开口160可以提供进入到贮存器152的内部容积，比如用于用添加剂1000填充贮存器152。贮存器152可以进一步包括盖子162，并且盖子162可以被配置为，当盖子162处于关闭位置(未示出)时，选择性地与入口158密封地接合，并且当盖子162处于打开位置(例如，如图5所示)时，允许进入到入口158。盖子162当处于关闭位置时可以通过任何合适的机构可移除地附接到入口158，比如但不限于卡扣配合、压配合、螺纹连接、卡口式连接或任何其他合适的连接。例如，如图5所示，在一些实施例中，盖子162可以铰接地附接到入口158，并且可以被配置为当盖子162处于关闭位置时经由卡扣配合来封闭入口158。如图3和图5所示，添加剂1000可以在入口158处被倒入贮存器中，如箭头1000所示。在图4中，添加剂1000被描绘为在贮存器152内。
现在转向图6和图7，示意性地示出了根据本公开的一个或更多个实施例的用于干燥机设备(比如但不限于上面示出和描述的干燥机设备10)的添加剂分配系统。如图6和图7所示，添加剂分配系统包括贮存器152、泵142和至少一个喷洒喷嘴146。如图所示，泵142可以连接到贮存器152和喷洒喷嘴146并与贮存器和喷洒喷嘴流体连通。例如，泵142可以在贮存器152的下游，使得流体(例如添加剂1000)从贮存器152向泵142流动，并且泵142可以在喷洒喷嘴146的上游，使得流体(例如添加剂1000)从泵142向喷洒喷嘴146流动(并且从喷洒喷嘴146流动到限定在滚筒26内的腔室25中)。
在一些实施例中，例如，如图6和图7所示，泵142可以是弹簧加载的泵。 例如，泵142可以包括活塞200。活塞200可以与泵的壳体220的内壁密封地接合，比如经由密封件202，例如图6和图7所示的O形环202，由此活塞200和密封件202限定了泵142内的流体体积，例如，进入泵142的流体可以由密封件202阻止或阻碍经过活塞200，并且流体可以占据的泵142内的体积可以取决于活塞200和密封件202的位置。在这样的实施例中，泵142可以进一步包括与活塞200操作性连通的弹簧204，例如，弹簧204可以比如在活塞200的上游或干燥侧连接到活塞200。从下面的描述中将变得清楚，活塞200的上游或干燥侧是活塞200的背离流动通过泵142的流体(例如添加剂1000)的一侧，并且通过密封件202与泵142内的流体体积隔离。由于弹簧204与活塞200之间的连接和/或操作性连通，弹簧204将活塞200朝向泵142的出口228(图7)推动，以将添加剂1000从泵142推到喷洒喷嘴146。
依旧参考图6和图7，在一些实施例中，泵142可以包括限定腔体218(图7)的壳体220。在一些实施例中，例如，如图6和图7所示，壳体220可以从第一端部222延伸到第二端部224。在这样的实施例中，壳体220可以终止于第一端部222和第二端部224中的每一个，并由第一端部和第二端部界定。例如，活塞200可以沿着轴向方向移动，例如，如图6和图7中的箭头302所示，并且壳体220可以沿着轴向方向从第一端部222延伸到第二端部224。
在图6和图7中可见，活塞200可以设置在腔体218内。在这样的实施例中，活塞200可以在腔体218内在靠近泵142的出口228的第一位置与远离泵的出口228的第二位置之间移动。如上文提到的，活塞200可以包括在其上的密封件202。在这样的实施例中，密封件202可以限定或勾画腔体218内的流体体积。例如，流体体积可以限定在泵142的入口226与密封件202之间。随着活塞200和其上承载的密封件202在腔体218内移动，腔体218内的流体体积膨胀和收缩。在一些示例实施例中，活塞200的第一位置可以是图6所示的位置，并且活塞200的第二位置可以是图7所示的位置，或者活塞200的第二位置可以比图7所示的位置更靠近第二端部224。例如，如下文将更详细地描述的， 当齿轮210上的多个齿212中的最后一个齿216与连接到活塞200的多个齿208中的相应齿脱离啮合时，可以到达活塞200的第二位置。在这样的实施例中，当活塞200从第一位置移动到第二位置时，活塞200将添加剂1000从贮存器152抽吸到腔体218中，并且当弹簧204推动活塞200从第二位置返回到第一位置时，活塞200将添加剂1000从腔体218推动到喷洒喷嘴146。
在一些实施例中，泵142可以包括齿条和小齿轮机构，该齿条和小齿轮机构被配置为例如通过将旋转运动转换成线性运动而使活塞200从第一位置移动到第二位置。在一些实施例中，泵142可以包括连接到活塞200的轴206。在这样的实施例中，轴206可以包括第一多个齿208。泵142可以进一步包括齿轮210，该齿轮可以连接到马达，比如连接到马达的驱动轴，以使齿轮210在方向300上旋转，例如在例如图6和图7所示页面上顺时针旋转。本领域普通技术人员可以理解示例性的马达及其驱动轴，因此，为了简洁和清楚起见，本文没有具体示出或进一步描述马达。
在一些实施例中，例如如图6和图7所示，泵142可以包括连接到活塞200的轴206，例如，轴206可以与活塞200一体地形成，并且轴206可以包括形成在其上的第一多个齿208。在这样的实施例中，齿轮210可以包括第二多个齿212。而且如图6和7所示，第二多个齿212可以仅部分地围绕齿轮210的圆周延伸。因此，轴206上的第一多个齿208可以选择性地与第二多个齿212啮合，由此齿轮210的旋转使轴206和连接到轴206(例如，与轴一体地形成)的活塞200从第一位置线性地移动到第二位置。当第二多个齿212仅部分地围绕齿轮210的圆周延伸时，第一多个齿208可以选择性地与第二多个齿212啮合，因为齿208和212仅在齿轮210的每转的一部分期间啮合。第二多个齿212可以包括第一齿214和第二齿216，并由第一齿和第二齿界定。第一齿214与第二齿216之间的间距(例如齿轮210的不包括第二多个齿212的圆周部分)可以限定齿208和212的选择性脱离啮合。例如，当齿轮210沿着方向300从第二多个齿212中的第一齿214与第一多个齿208中的相应齿之间的初始啮合点旋转时， 齿208和212可以啮合，直到齿轮210旋转到当齿轮210旋转经过第二多个齿212中的最后一个齿216时(例如当第二多个齿212中的最后一个齿216与第一多个齿208中的相应齿脱离啮合时)齿轮210与轴206脱离啮合的点。继续该示例，齿208和212然后可以在齿轮210沿着方向300的每转的一部分(该部分在最后一个齿216之后并且在第一齿214之前)期间脱离啮合。
在各种实施例中，泵142可以进一步包括偏压元件，例如弹簧204，其位于壳体220内并联接到活塞220。因此，当齿轮210将活塞200移动到第二位置时，例如如图7所示，活塞200可以压缩偏压元件(例如弹簧204)，在该第二位置，弹簧204几乎被完全压缩在活塞200与壳体220的第二端部224之间。因此，当齿轮210与轴206脱离啮合时，偏压元件(例如弹簧204)可以将活塞200从第二位置推动到第一位置。例如，当第二多个齿212中的最后一个齿216旋转经过第一多个齿208中的与最后一个齿216啮合的相应齿时，轴206和活塞200不再被限制沿轴向方向(轴向方向例如如图6和图7中的箭头302所示，如上文提到的)朝向壳体220的第一端部222的移动，使得压缩的弹簧204然后可以朝向壳体220的第一端部222推动活塞200，例如，弹簧204可以推动活塞200返回到第一位置，在该第一位置，活塞200靠近壳体220的第一端部222。如下文将更详细地描述的，当处于第一位置时，活塞200还可以靠近一个或更多个阀250和260、泵142的入口226和/或泵142的出口248，在各种实施例中，以上这些中的一些或全部可以定位在壳体220的第一端部222处。
在一些实施例中，如图6和图7所示，泵142可以包括入口226和出口228，例如，入口226和出口228可以形成在壳体220中，并且可以提供与腔体218的流体连通，例如，进入和离开腔体的流体流动。泵142可以通过第一单向阀250(例如，定位在壳体220的入口226中或入口处)连接到贮存器152，并且泵142可以通过第二单向阀260(例如，定位在壳体220的出口228中或出口处)连接到喷洒喷嘴146。例如，如图6和图7所示，第一单向阀250可以被定位和配置为提供或允许仅从贮存器152到泵142的流体连通，并且第二单向阀260 可以被定位和配置为提供或允许仅从泵142到喷洒喷嘴146的流体连通，例如，单向阀250和260可以防止或阻碍从喷洒喷嘴146到泵142和/或从泵142到贮存器152的流体流动。例如，如图6和图7所示，第一单向阀250可以包括柱塞252和偏压元件254。偏压元件254可将柱塞252朝向贮存器152偏压，使得从贮存器152流向泵142的流体可以克服偏压元件254的偏压力，从而打开第一单向阀250(例如，如图7所示)，以允许从贮存器152到泵142的流体流动，例如，如图7中箭头1000所示的添加剂的流动。相反，从泵142到贮存器152的流体流动将与第一单向阀250的偏压元件254的偏压力一致，而不是相反，由此这种流动不会使第一单向阀250的柱塞252移动，并且不会打开或经过第一单向阀250。类似地，第二单向阀260也可以包括柱塞262和偏压元件264，它们在结构和功能上可以与上面描述的第一单向阀250的相应部分大致相同，除了第二单向阀260可以与第一单向阀相反地定向，由此当从壳体220内的腔体218流动的流体的力足以克服偏压元件264的偏压力并打开第二单向阀260时，第二单向阀260允许从泵142到喷洒喷嘴146的流体流动，而从喷洒喷嘴146到泵142的流体流动将与偏压元件264的偏压力一致，例如沿着相同的大致方向，因此不会打开第二单向阀260。
在一些实施例中，如图6和图7所示，入口226和出口228可以各自定位在壳体220的同一端部处，例如，定位在如图6和图7所示的第一端部222处。在这样的实施例中，第一单向阀250和第二单向阀260因此也可以位于壳体220的同一端部(例如第一端部222)处。因此，在这样的实施例中，当活塞200从第一位置移动到第二位置时，活塞200可以远离第一单向阀250移动，以通过第一单向阀250将流体(例如添加剂1000)抽吸到其腔体218中，并且当活塞200从第二位置移动到第一位置时，活塞200可以朝向第二单向阀260移动，以通过第二单向阀260将流体(例如添加剂1000)从腔体218推动到喷洒喷嘴146。此外，如图6所示，添加剂1000然后可以经由喷洒喷嘴146(比如通过喷洒喷嘴146中的一个或更多个孔口148)喷洒到滚筒26内的物品2000上。
在各种实施例中，泵142可以仅在特定的一组操作参数存在时启动，例如当加热系统40关闭并且滚筒26转动时。例如，当加热系统40关闭时启动泵142可以在干燥循环之后立即发生，或者在干燥循环之后的短暂延迟(例如几秒钟)后发生。这样，当来自贮存器152的添加剂被喷洒到腔室25中时，腔室25内的衣物仍然可以是温暖的，例如，相对于室温处于升高的温度，这可以促进或增强某些添加剂(例如香料)的效果。喷洒添加剂的同时旋转滚筒26可以促进添加剂在腔室25内的衣物上的均匀分布，并且在一些情况下可以提供额外的益处。例如，当添加剂包括除皱剂时，由于篮框26的旋转而搅动衣物可以增加除皱剂的有效性。在一些实施例中，泵142可以在篮框25不转动时和/或当鼓风机风扇不操作时启动，以减少来自喷洒喷嘴146的添加剂被抽吸到干燥机设备10的空气循环系统中。在一些实施例中，泵142可以响应于用户选择而启动，用户选择可以经由一个或更多个输入70来选择。例如，可以为一个或更多个标准的干燥机循环提供专用的“再芬芳”循环和/或“添加香味”选项。在一些实施例中，当干燥循环完成后经过一定时间且门33没有被打开时，泵142可以自动地启动，这表明物品可能已经在腔室25中保留了较长的时间。
该书面描述利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相结合的方法。本发明的可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，则这样的其他示例旨在在权利要求的范围内。
