Description

真空吸尘器及其气旋模块
技术领域
本发明涉及真空吸尘器，特别地涉及具有气旋灰尘分离装置的真空吸尘器。在其一个方面，本发明涉及一种具有改进的排气格栅的气旋分离器。
背景技术
利用气旋分离器的真空吸尘器是已知的。某些气旋分离器仿效采用截头圆锥形的分离器的教科书实例，其它的采用空气/灰尘的高速旋转运动以通过离心力分离灰尘。典型地，气旋分离室在竖直堆积定向上定位在集尘室的上方。工作空气在气旋分离器的上部进入和离开，碎屑被收集在下部中。可选择性地，气旋分离器和集尘室可以在气旋模块中水平定向。这种定向可以减小气旋模块的总高度，这对于筒式真空吸尘器是特别理想的，以便降低重心和改进单元沿地板滚动时的稳定性。
BISSELL Homecare，Inc.开发了一种双功能筒式真空吸尘器，其可以容纳标准的真空过滤袋或可互换的无袋式气旋模块。气旋模块被构造成使得气旋分离室沿水平面定位在灰尘容器附近。流动通过气旋分离器的空气在通过位于气旋模块底部的过滤组件离开气旋模块之前通过排气格栅。该排气格栅构造成易于被使用者移除，以对该排气格栅进行清洁。
Lee的美国专利No.7,381,236公开了一种具有平行布置的气旋分离室和气旋集尘室的气旋模块，其中，集尘器具有布置在灰尘室的一个侧壁处的逆流阻止构件，以防止收集的灰尘流回到气旋室中。
Oh的美国专利申请公开No.2006/0130441公开一种用于气旋分离器的排气格栅，其中，格栅中的空气通道具有朝向格栅周围的气流的方向的引导表面。据公开，空气直接流动进入格栅防止了在格栅空气通道中形成停滞旋涡，从而防止碎屑积聚。
Bock的美国专利No.7,445,655公开了一种可以容纳过滤袋或集尘容器的筒式真空吸尘器，该过滤袋或集尘容器具有夹持部，以保持袋关闭板。灰尘舱中的枢转架包括与灰尘舱的边缘重叠的锁定构件，使得当没有过滤袋或集尘器时，不能关闭真空吸尘器的盖。
发明内容
按照本发明，真空吸尘器包括具有吸入腔的吸尘器主体，吸入腔具有入口端口和出口端口，并适于接收可移除的气旋模块。气旋模块包括具有入口开口和气旋出口开口的分离室，所述入口开口设置在气旋模块的下部，并适于与所述入口端口连通，所述气旋出口开口适于与所述出口端口连通。排气格栅被安装在分离室中并与所述气旋出口流体连通。与分离器入口开口相邻的倾斜件适于沿分离室在向上螺旋路径中引导通过入口进入的脏空气，用于将灰尘或碎屑从空气中分离。位于分离室上部的碎屑出口将碎屑引导到集尘室中，该集尘室与分离室相邻并与碎屑出口连通，用于收集从分离室中的空气分离的碎屑和灰尘。安装在吸尘器主体中的真空风扇/马达具有与入口端口连通的吸入口，所述真空扇/马达适于在所述入口开口和所述气旋出口之间保持从所述入口端口通过所述气旋分离室的脏空气流。
在一个实施例中，排气格栅适于能够从气旋出口上方的分离室移除，气旋出口形成在分离室的下部。气旋模块还包括与气旋出口流体连通并可移除地安装至分离室的过滤器组件。
按照本发明的另一个实施例，用在真空吸尘器中的气旋模块包括分离室，该分离室具有位于分离室下部的入口开口，该入口开口适于与入口端口连通。气旋模块还具有气旋出口开口，该气旋出口开口形成在所述分离室的下部，并适于与出口端口连通。排气格栅被安装在分离室中，并且与气旋出口流体连通。倾斜件定位成与入口开口相邻，并适于沿分离室在向上螺旋路径中引导进入入口开口的脏空气，用于将灰尘或碎屑从空气中分离。碎屑出口定位在分离室的上部，集尘室定位成与分离室相邻，并与碎屑出口连通，用于收集从分离室中的空气分离的碎屑和灰尘。
在一个实施例中，排气格栅可移除地安装在分离室中并位于气旋出口的上方。在另一个实施例中，过滤器组件流体地连接至气旋出口。此外，过滤器组件可移除地安装至分离室。

具体实施方式
参照附图，特别地参照图1和2，按照本发明的筒式真空吸尘器10包括：吸尘器主体12；用于从待清洁的表面吸取灰尘和碎屑的清洁头14；延伸杆组件16；和柔性软管18，该柔性软管18具有附接至吸尘器主体12和杆组件16的入口连接器20和出口连接器22。一对后轮24被安装至吸尘器主体12的后部，并且较小的转动轮26被附接至前部，用于在待清洁的表面上的运动。马达腔形成在吸尘器主体12中并位于上壳体28和下壳体30之间，用于容纳在该马达腔中横向定向的传统的真空风扇/马达组件(未示出)。如图2中所示，枢转地安装的盖32连接至上壳体28，并被构造为选择性地封闭在上壳体28中形成的吸入腔34。盖32上的入口端口36包括密封组件35，以密封地接收软管出口连接器22，由此当盖32被密封至上壳体28时，流体地将软管18连接至吸入腔34。枢转闭锁组件38被安装至盖32的前部，并选择性地将盖32固定至上壳体28，由此封闭吸入腔34。通道格栅40设置在吸入腔34的后壁上，以为吸入源(未示出)提供空气路径。吸入腔34接收可移除的气旋模块42，该气旋模块42被构造成将灰尘离心地从工作气流中分离。当吸入腔34被盖32封闭时，包含在吸入腔34中的气旋模块42流体地连接至出口侧上的吸入源(未示出)和入口侧上的柔性软管18，由此产生从清洁头14通过延伸杆16、软管18、密封组件35、气旋模块42和吸入马达组件(未示出)的工作空气路径。在一种替换构造中，过滤袋组件44可以取代吸尘器主体12的吸入腔34内的可互换气旋模42。过滤袋组件44包括公知的过滤袋45，该过滤袋45通过弹性夹持部49固定至袋安装板47。安装板包括用于将组件安装在吸入腔34内的下部，该下部包括U型边缘51。U型边缘51被滑动地接收在L型安装通道53中，该L型安装通道53形成在吸入腔34的前壁上。弹性夹持部49被枢转地安装在形成在袋安装板47的顶部处的凹槽中。夹持部49将过滤袋45固定至安装板，使得袋入口孔55与安装板孔57对齐，该安装板孔57与吸尘器主体盖32上的入口端口36共轴，用于在接合时形成它们之间的流体连通。
参照图3，气旋模块42包括气旋主体46，该气旋主体46具有被可移除的气旋盖48覆盖的打开的顶部和被气旋基部50覆盖的部分打开的底部。气旋基部50适于在底部上接收可移除的过滤器组件52。气旋主体46还包括分离室54，该分离室54由从底壁悬挂的圆柱壁56限定的，并位于气旋主体46的后拐角部。圆柱壁56将气旋主体的内部部分隔成分离室54和集尘室58。工作空气入口管60从底壁突出，并终止于平面62中，该平面62支撑用于连接至枢转安装的气旋盖48的下侧的可压缩密封装置64。沿气旋主体46的底部并与外壁相邻地设置的入口导管66(图4-5)将工作空气入口管60连接至分离器壁56的基部，从而在它们之间形成空气路径。
现在参照图3-7，气旋分离器68包括入口70、排气格栅72、气旋出74和碎屑出口76。矩形入口70位于分离器壳体的基部；邻近气旋主体46的侧壁和底壁。参照图5和6，排气格栅72包括具有多个排气孔78的圆柱部分，其中该排气孔78与气旋出口74流体连通。排气格栅72还包括从下圆柱部向外延伸的倾斜凸缘82。倾斜凸缘82跟随逆时针螺旋轨迹，以引导工作气流以及被朝向碎屑出口带走的碎屑。排气格栅72还包括从倾斜凸缘的周边向下延伸的套管84。两个锁定突起86从套管84向内延伸，用于选择性地与从气旋出口74相反侧上的气旋基部50突出的相对应的安装钩88接合。每个钩88都包括用于保持排气格栅突起86的定位槽89。定向肋87沿套管84的内壁从底部边缘延伸到凸缘82的底部。定向肋87确保排气格栅72的适当定向。
下面参照图3-5，碎屑出口76包括与竖直侧壁92侧面相接的水平引导构件90，并且还包括用于将碎屑出口保持到位于分离室54的顶部处的切口96中的咬扣突片94。气旋盖48的底表面与碎屑出口76的打开的顶侧配合，从而形成从分离室54延伸进入集尘室58的碎屑引导通道98。碎屑出口76优选地定位在气旋主体的顶部附近，以使气旋主体46的底壁和水平引导构件90之间的竖直距离最大化。这种优选的定向使碎屑被再次带走的可能性最小化，并允许气旋盖形成碎屑引导通道98的顶表面，从而减少所需的原材料并降低所需部件的可能数量。
气旋出口74(图3)被顶侧上的可移除的排气格栅72覆盖。出口的底侧与在气旋基部50中形成的过滤器室100连通。出口74包括大致半圆形的孔，该大致半圆形的孔具有格栅，该大致半圆形的孔的格栅具有从孔的中心径向向外突出到过滤器室100的外周的肋102。径向肋102使过滤介质与气旋基部50的底表面间隔开，并形成用于横过并通过过滤器表面引导并分配空气的流动通道104。
现在参照图3-5，可移除的过滤器组件52包括第一多孔泡沫过滤层108，第二褶皱过滤介质层110背靠在第一多孔泡沫过滤层108上，用于捕获在气旋主体46内未被分离的细小的灰尘。过滤介质108、110的组合被安装在过滤器箱体112中，该过滤器箱体112可以选择性地从气旋基部50移除，以进行清洁或替换。过滤器箱体112包括托盘结构，该托盘结构在底侧上具有格栅框架114，用于支撑过滤介质。两个突起116在后壁上形成，该两个突起116接合气旋基部50上的配合槽118。过滤器箱体112的前壁上的整体模制的闭锁件120与在气旋基部50上形成的倾斜突起122接合，以将过滤器箱体112保持在固定的位置上。弓形的支撑装置124从气旋基部50的底表面在气旋基部的相反侧上延伸，以使过滤器箱体112与吸入腔34的底部竖直地间隔开，以防止气流被阻塞或受到限制。可以预期的是，过滤介质可以包括很多种材料，包括无纺织物、HEPA、或任意其它适当的过滤材料。
气旋盖48可移除地安装至气旋主体46的顶部。手柄126在气旋盖48的顶部形成，用于运送气旋模块42，并用于将气旋盖48从气旋主体46移除，以清空碎屑或对单元进行清洁。钩128从气旋主体46的后壁突出，用于枢转地保持气旋盖48。被安装至气旋主体46的前壁的过中心(over-center)闭锁组件130将盖132接合在盖48上，以将其固定至主体46，并压缩被捕获在它们之间的绳状密封装置134。盖48还包括用于将工作空气入口管60流体地连接至吸尘器主体盖32上的入口端口36的入口孔129。
现在参照图7-10，清洁头14包括支撑管嘴140的壳体138、刷子组件142和用于从待清洁的表面吸取灰尘和碎屑的关节相连的导管144。管嘴140被固定在壳体138的前部的下面，并与待清洁的表面流体连通。关节相连的导管144提供从管嘴到导管出口146的空气路径。关节相连的导管144具有围绕水平轴线枢转的第一接头和旋转360度的第二接头。导管出口146的尺寸被设置为接收延伸杆组件16。壳体138还支撑被安装在形成在壳体顶部上的凹槽内的装饰性插入物139。小轮141被安装在壳体的后部，用于在待清洁的表面上运动。可缩回的刷子组件142弹性地安装在管嘴140和壳体138之间，用于与清洁表面选择性地接合。刷子组件142包括刷子板148和设置在拖动边缘上的橡皮刮板152，该刷子板148将条形刷子150固定在前缘上。刷子板148放置在可压缩的螺旋弹簧154上。刷子板148的顶表面可操作地连接至偏置凸轮杆156，用于接合刷子板148和使刷子板148缩回。偏置凸轮杆156包括具有偏置中心部分的可旋转安装的杆，该偏置中心部分提供可运动的凸轮接触表面，以作用在刷子板148的顶表面上。在组装后，条形刷子150位于壳体138的前壁和管嘴前缘之间，而橡皮刮板152位于管嘴的拖动边缘和壳体后壁之间。偏置凸轮杆156包括可由使用者操作的整体控制杆158，以接合刷子板148或使刷子板148缩回。可以预期的是，多种清洁头可以互换地与前面公开的吸尘器主体12一起使用。一种适当的替换包括具有图8-10中示出的并在未决的美国专利申请No.11/683,744中公开的毛发收集组件160的真空吸尘器头14’，其中该专利申请通过引用被结合于此。该专利申请No.11/683744公开了包括毛发收集组件160的真空吸尘器头，该毛发收集组件160具有适于从一个表面收集毛发的毛发收集元件162。毛发收集元件可以被安装至清洁头14’，用于在使用位置和第二位置之间运动，其中在该使用位置，毛发收集元件与待清洁的表面接触(图8和9)；而在该第二位置，毛发收集元件与待清洁的表面138间隔开(图10)。
如图4和5中的箭头表示的那样，风扇/马达组件(未示出)被定位在气旋出口74的下游。风扇/马达组件通过清洁头管嘴140吸入空气。空气通过关节相连的导管144、延伸杆16和柔性软管18。然后，包含碎屑的工作空气从工作空气入口管60吸入，通过入口导管66，并进入分离器入口70。空气进入分离室54，并在分离室54的圆柱壁56周围转动。向上倾斜的凸缘82在顺时针方向上以螺旋方式引导工作空气，从而沿分离室的壁向上流动。灰尘和碎屑从空气流中分离，并离开碎屑出口76而进入集尘室58。然后，空气通过排气格栅孔78离开分离室54，在那里空气通过气旋出口74，并流入过滤器室100。空气由位于气旋基部50的底侧上的径向肋102形成的流动通道104沿着过滤介质110引导，并被引导通过该过滤介质110。过滤器组件52捕集气流中带走的任何残留的细小的灰尘。在离开过滤器组件52后，空气流动通过在吸入腔34的后壁中形成的通道格栅40，并进入马达腔(未示出)，在马达腔中，空气被风扇/马达组件(未示出)吸入，并通过吸尘器主体12后侧的马达排气孔(未示出)排出。在使用过程中，使用者可以通过压下致动杆158而选择性地接合刷子组件142。杆158与偏置凸轮杆156整体地形成，并被构造为使偏置凸轮杆156在两个位置之间旋转。当杆158被偏压到向前的位置时，凸轮杆156使凸轮表面157旋转远离刷子板148，并且螺旋弹簧154将板148推到向上位置，从而使刷子组件142缩回。当杆158被朝向向后的位置偏压时，凸轮杆156使凸轮表面157旋转，以接触刷子板148，并迫使它向下，这样可以压缩螺旋弹簧154，并使刷子组件142抵靠待清洁的表面。如前面讨论的那样，可以预期的是，多种公知的清洁头组件可以互换地与吸尘器主体12一起使用，这些公知的清洁头包括具有宠物毛发收集构件和/或安装在管嘴中的旋转刷子辊等的清洁头。
虽然已经结合某些特定的实施例对本发明进行了具体地描述，但是应当理解的是，这是例证性的，而不是限制性的。可以预期的是，所描述的特征可以被应用到利用单个气旋、或布置成串连气流或并联气流的任意组合的两个或多个气旋的气旋分离装置。此外，虽然本发明对筒式真空吸尘器进行了描述，但是本发明还可以与其它形式的真空吸尘器(例如竖立或中心真空吸尘器)一起使用。在不背离由所附的权利要求书限定的本发明的精神的前提下，可以对前面公开的内容和附图进行适当的变化和修改。
