Description

可转换的表面清洁设备
技术领域
本发明涉及具有地板上方清洁模式的表面清洁设备。更具体地说,本发明涉及能够转换成可手提或带携式表面清洁设备的立式表面清洁设备。
背景技术
能够从地板清洁模式转换成地板上方清洁模式的立式真空吸尘器是已知的。这种真空吸尘器通常包括阀,该阀可操作以将该真空吸尘器从地板清洁模式转换成地板上方清洁模式。该阀通常设置在表面清洁头中。如果手动操作该阀,那么为了致动该阀,使用者弯下腰并且致动与该阀相关的控制器。
发明内容
在一个广义方面,本发明提供一种立式表面清洁设备。该设备能够从地板清洁模式转换成地板上方清洁模式。该设备包括具有脏流体入口的表面清洁头。流体流动路径从该脏流体入口延伸到该表面清洁设备的清洁空气出口,并且包括抽吸马达和至少一个清洁级。竖直部分安装于表面清洁头并且包括至少一个具有入口的清洁级。地板上方清洁棒能够连接于流体流动路径并具有入口端。阀可在第一位置和第二位置之间操作,在该第一位置表面清洁头与该至少一个清洁级处于流体流连通状态,在该第二位置,地板上方清洁棒与该至少一个清洁级处于流体流连通状态。该阀定位成靠近该至少一个清洁级的入口。
根据这个广义方面的实施例可以是有利的,因为使用者无需弯腰、屈膝或下蹲就能够致动该阀。因此,该表面清洁设备比较容易从地板清洁模式转换成地板上方清洁模式。而且,通过在清洁级的入口处、优选在旋风器入口处设置阀,可以减小从脏空气入口到清洁级入口的导管长度,以及该导管中的弯曲数目。这可以减少由通过该导管的流体流产生的背压。
在一些实施例中,抽吸马达设置在竖直部分上。在一些实施例中,抽吸马达设置在该至少一个清洁级的入口上方。
在一些实施例中,抽吸马达设置在竖直部分上,并且表面清洁设备在该至少一个清洁级下游没有延伸到表面清洁头的下流管道。这种设计的优点是能够减小该清洁级下游的导管长度以及该导管中的弯曲数目。这可以减小由通过该导管的流体流产生的背压。
在一些实施例中,清洁空气出口设置在竖直部分上。
在一些实施例中,阀设置在地板上方清洁棒固定在其上的壳体中。在另一个实施例中,地板上方清洁棒的入口端固定于壳体。
在一些实施例中,至少一个清洁级包括旋风清洁级。
在一些实施例中,表面清洁设备包括上流管道,该上流管道安装于该表面清洁头,并且沿着该至少一个清洁级在外部延伸到靠近该至少一个清洁级的入口的位置。在另一些实施例中,阀安装于上流管道。
在一些实施例中,表面清洁设备还包括抽吸和过滤单元,该抽吸和过滤单元包括抽吸马达、至少一个清洁级、地板上方清洁棒以及阀,其中该抽吸和过滤单元可以从表面清洁设备拆卸。在另一些实施例中,抽吸和过滤单元还包括携带把手和肩带中的至少一个。
在另一个广义方面,提供一种立式表面清洁设备。该立式表面清洁设备包括具有脏流体入口的表面清洁头。流体流动路径从该脏流体入口延伸到该表面清洁设备的清洁空气出口,并且包括抽吸马达和至少一个具有入口的清洁级。竖直部分安装于表面清洁头,并且具有下部、中部和上部。地板上方清洁棒能够连接于流体流动路径并具有入口。阀可在第一位置和第二位置之间操作,在该第一位置表面清洁头与该至少一个清洁级处于流体流连通状态,在该第二位置,地板上方清洁棒与该至少一个清洁级处于流体流连通状态。阀定位在竖直部分的下部上方。
在一些实施例中,至少一个清洁级设置在竖直部分上。
在一些实施例中,抽吸马达设置在竖直部分上。在一些实施例中,抽吸马达设置在该至少一个清洁级的入口上方。在另一些实施例中,抽吸马达设置在竖直部分上,并且表面清洁设备在该至少一个清洁级下游没有延伸到表面清洁头的下流管道。
在一些实施例中,清洁空气出口设置在竖直部分上。
在一些实施例中,阀设置在地板上方清洁棒固定在其上的壳体中。在另一些实施例中,地板上方清洁棒的入口端固定于壳体。
在一些实施例中,该至少一个清洁级包括旋风清洁级。
在一些实施例中,该设备还包括上流管道,该上流管道安装于表面清洁头,并且沿着该至少一个清洁级在外部延伸到靠近该至少一个清洁级的入口的位置。在另一些实施例中,阀安装于上流管道。
在一些实施例中,该设备还包括抽吸和过滤单元,该抽吸和过滤单元包括抽吸马达、至少一个清洁级、地板上方清洁棒以及阀,其中该抽吸和过滤单元式可从表面清洁设备拆卸。在另一些实施例中,抽吸和过滤单元还包括携带把手和肩带中的至少一个。

具体实施方式
参考图1,示出本发明的表面清洁设备10的实施例。在示出的实施例中,表面清洁设备10是立式真空吸尘器。在另一些实施例中,表面清洁设备10可以是其他类型的表面清洁设备,例如具有上部分的地毯抽洗机。
如例示的,表面清洁设备10包括表面清洁头12和包括抽吸和过滤单元15的竖直部分14。脏流体入口16设置在表面清洁头12中。流体流动路径从该脏流体入口16延伸到清洁空气出口18。在所示的实施例中,清洁空气出口18设置在竖直部分14中。在另外的一些实施例中,清洁空气出口18可以设置在表面清洁头12上。该流体流动路径包括抽吸马达20和至少一个清洁级22。
竖直部分14相对于表面清洁头枢转地安装。在例示的优选实施例中,空气进入在表面清洁头中12中的脏流体入口16,并且被引导到上流管道24。上流管道24通过枢转连接器26枢转地安装于表面清洁头12。因此,正如例示的,上流管道24起支撑物的作用,竖直部分14支撑在其上。因此,不需要诸如通常与立式真空吸尘器一起使用并且用模制塑料制造的单独的外壳。因此,通过利用上流管道24作为支撑竖直部分14的部件,能够生产轻重量的产品。在这样的实施例中,上流管道可以用金属、碳纤维或其它高强度材料制造。在另外一些实施例中,可以设置单独的支撑物(未示出)用于支撑该竖直部分14,并且单独的导管(例如柔性软管)可以用于以与该表面清洁头流体流连通的方式连接该竖直部分。可选地,可以用具有脊柱的外壳。
在例示的实施例中,优选提供壳体28。壳体28起安装部件的作用,表面清洁设备的一个或多个操作构件(例如,过滤器壳体、旋风器室和/或抽吸马达)连接于该壳体并且该壳体安装于上流管道24或其它支撑部件。在这种优选构型中,优选壳体28包括气流通道。如果设置壳体28,那么壳体28优选包括在上流管道24和竖直部分14之间延伸的通道38,并且在它们之间提供流体连通。正如例示的,壳体28包括主体30、下部分32和上部分34。
正如图1中例示的,壳体28的主体30包括固定部件40。竖直部分14的旋风室42定位在该固定部件40下面,并且竖直部分14的过滤器壳体44定位在固定部件40的上面。然后,通过延伸穿过壳体28或独立于壳体28的开口,旋风室42和过滤器壳体44例如用螺钉、螺栓、螺纹、粘结剂、卡口固定件或焊接相互固定。在另外的一些实施例中,壳体28可以与竖直部分14的操作构件一体地形成。还应当理解,只有一个操作构件可以固定于壳体28。
在所示的实施例中,壳体28的上部分34可拆卸地接纳连接于把手70的把手或棒(wand)延伸部分68。正如在下面进一步描述的,把手延伸部分68可拆卸地安装在上部分34中,并且包括经由软管72与上部分34流体连通的入口69,使得把手延伸部分68可以被转换成地板上方清洁棒。
优选地壳体28可拆卸地安装于上流管道24或其它支撑部件。可以用任何可释放的安装系统。正如例示的,下部分32可拆卸地连接于上流管道24。例如,在所示的实施例中,下部分32包括上流管道插入其中的开口36。上流管道24例如可以用诸如插销(latch)的锁定机构,或通过摩擦或卡紧配合,或者粘结剂或焊接,固定在开口36中。开口36经由设置在壳体28中的气流通道38与清洁级22处于流体连通状态。壳体28可以用任何其它手段固定于上流管道24,例如被安装于固定在上流管道24的平台(未示出)。
在另外的一些实施例中,可以不设置壳体28,并且上流管道24可以直接连接于竖直部分14。在这样的实施例中,竖直部分14可以直接安装于上流管道24,或可以设置支座(未示出),其将竖直部分14可拆卸地安装于上流管道24。在其中除了上流管道24之外还设置支座(未示出)的另外的又一些实施例中,上流管道24可以直接连接于竖直部分14,或可以设置另外的连接器,其以流体连通的方式连接上流管道24与竖直部分14。而且,支座可直接安装于竖直部分14,或支座(未示出)可设置成将竖直部分14可拆卸地安装于该支撑物。
应当理解,根据本发明的一方面,整装的(self-contained)清洁和抽吸单元(即,包括一个或多个清洁级和抽吸马达)以及地板上方清洁棒68和阀的真空吸尘器的一部分可以从该表面清洁设备的其余部分拆卸。根据本发明的另一方面,整装的清洁和抽吸单元可以不是可拆卸的。
在所示的实施例中,空气从气流通道38被引导到竖直部分14中。在所示的实施例中,竖直部分14包括靠近壳体28的中部46、在该中部46下面的下部48以及在该中部46上面的上部52,该中部46优选包括旋风清洁级22和过滤器壳体44,该下部48优选包括脏物箱,该上部52优选包括抽吸马达20。在另一些实施例中,竖直部分14可以另外构造。例如,上部52可以包括旋风清洁级22,中部46可以包括脏物箱50,而下部48可以包括吸马达20。可选地,中部46可以包括过滤器壳体44,下部48可以包括旋风清洁级22和脏物箱50,而上部52可以包括附加的清洁级(未示出)和抽吸马达20。应当理解,竖直部分可以包括一个或多个清洁级,一个或多个清洁级可以是旋风清洁级。每个清洁级可以包括单个旋风器或并行的多个旋风器。
正如在图2中例示的,使用旋风清洁级。因此,空气从气流通道38被引导到旋风清洁级22。在该优选实施例中,空气以切线运动进入旋风清洁级22。因此,气流通道38可以沿着清洁级22的外表面在外部延伸到该旋风清洁级22的入口54附近的位置,使得空气切向进入该入口54。在其中不设置壳体28的另外的实施例中,上流管道24可以沿着清洁级22的外表面在外部延伸到旋风清洁级22的入口54附近的位置。
在所示的实施例中,清洁级22是旋风清洁级,包括单个旋风室42,具有清洁空气出口58和脏物出口60。在另外的实施例中,清洁级22可以另外构造。例如,清洁级22可以包括并行的多个旋风室。
脏物室50优选设置在脏物出口60的下面,用于收集从旋风室24中的空气中分离的物质。优选地,脏物室是能够打开的,例如用于倒空。在所示的实施例中,脏物室50能够从旋风室42可滑动地拆卸,使得它可以被倒空。在另外的一些实施例中,旋风室42的底部可以枢转地安装于旋风室42,使得它可以被倒空或可以与旋风室42一起被拆卸。
在一些实施例中,分隔器板61可选地与脏物出60相关联。分隔器板61可以定位在脏物出60的下面,在脏物室50内,如图2所示。可选地,分隔器板可以定位在脏物出60处,或在脏物出口50上方。分隔器板50可以具有任何已知的构型并且可以安装在任何已知的位置。
在所示的实施例中,优选空气从空气出58进入过滤器组件62。过滤器组件62包括容纳一个或多个过滤部件64的过滤器壳体44。在所示的实施例中,表面清洁设备只包括一个过滤器组件62。在另外的一些实施例中,可以设置多于一个的过滤器组件。
在所示的实施例中,优选地空气从过滤器组件62被引导到容纳在马达壳体66中的马达20。虽然马达20可以设置在竖直部分14中或表面清洁头12中,但是优选设置在竖直部分14中。在其中马达20设置在表面清洁头12中的实施例中,下流管道(未示出)可以设置在竖直部分14和表面清洁头12之间。在其中马达20设置在竖直部分14中的实施例中,可以不设置下流管道。
在图1所示的实施例中,表面清洁设备10处于地板清洁模式。优选表面清洁设备10构造成能够转换成如图3所示的地板上方清洁模式,这在下面描述。
参考图4A-4B和5A-5B,设置软管72,并且该软管在其第一端74与竖直部分14流体连通。软管72的第二端76与把手延伸部分68流体连通,在地板上方清洁模式中,把手延伸部分68用作地板上方清洁棒。
阀78设置在软管72和上流管道24之间。阀72可以具有任何已知的结构。优选地,正如例示的,阀72能够从图4B所示的第一位置旋转到图5B所示的第二位置。当阀78处于第一位置时,表面清洁头12与清洁级22流体连通,并且基本防止软管72和清洁头12之间的流体连通。因此,表面清洁设备可以用于地板清洁模式,并且空气可以沿着箭头A1所示的方向流动。当阀78处于第二位置时,软管72(和地板上方清洁棒68)与清洁级22处于流体连通状态,并且基本防止表面清洁头12和阀78之间的流体连通。因此表面清洁设备10可以用于地板上方清洁模式,并且空气可以沿着箭头A2所示的方向流动。正如在图1中能够看到的,设置例如杆80的控制器,用于在第一位置和第二位置之间旋转阀78。在另外的一些实施例中,控制器可以是例如按钮或开关,并且当把手延伸部分68从壳体28拆下时它可以自动致动。
在例示的实施例中,阀78设置在壳体28的气流通道38中,并且定位在旋风清洁级22的入口54附近。也就是,阀78设置在竖直部分14的下部48上方,靠近中部46。在另外的一些实施例中,阀78可以设置在上流管道24中。在这样的实施例中,阀78可以设置在下部48附近,或靠近中部46。在另外一些的实施例中,阀78可以设置在软管72中,或把手延伸部分68中。在这样的实施例中,阀78可以设置在中部46附近或上部分52附近。
其中阀78在下部48附近或在下部48上方的这种实施例可以是有利的,因为使用者可以不必弯腰或蹲下来致动控制器80而能够将表面清洁设备10从地板清洁模式转换到地板上方清洁模式。
在又一些实施例中,当表面清洁设备处于地板上方清洁模式时,表面清洁设备可以转换成能够手提或带携式表面清洁设备。参考图3,正如在前面所提到的,包括抽吸和|抽吸单元15|的竖直部分14可以可拆卸地安装于表面清洁头12。例如,在所示的实施例中,上流管道24插入壳体28的开口36中,并且通过摩擦配合固定在其中。因此,使用者可以提起竖直部分14脱离上流管道24,并且可以利用设置在竖直部分14上的带82或把手84携带抽吸和抽吸单元15。
应当理解,设置阀78可以用在其中竖直部分14、或整装的清洁和抽吸单元15不能从表面清洁设备拆卸的实施例中。在这种情况下,表面清洁设备优选利用上流管道24作为用于竖直部分14的底座。此外,这里说明的每个可选的特征可以用于这样的实施例中。
应当理解,为了清楚起见,在单独的实施例或单独的方面的上下文中所描述的本发明的某些特征,也可以以组合方式用于单个实施例。相反,为了简洁起见,在单个实施例或单个方面的上下文中所描述的本发明的多种特征也可以单独地或以任何合适的子组合的方式应用。
虽然已经结合其具体实施例描述了本发明,但是,很明显许多可选的方案、修改和变化对于本领域的技术人员来说是很显然的。因此,本发明旨在包含属于权利要求的精神实质和广义范围内的所有的这种可选的方案、修改和变化。此外,在本申请中任何参考文献的引用或标识不应当解释为承认该参考文献可以用来作为本发明的现有技术。
