Description
技术领域
本发明涉及开关和马达组件,其用于表面处理设备,例如真空吸尘器。
背景技术
多数真空吸尘器是“立”式或“筒”式(cylinder type)的,在一些国家称为罐或桶吸尘器。立式真空吸尘器通常包括容纳灰尘分离装置的主体、旋转地安装在主体上且具有脏空气入口的吸尘器头、以及马达和风扇单元,该单元用于经由脏空气入口把脏空气吸入灰尘分离装置以使得在清洁的空气排放到大气之前灰尘被从气流分离。脏空气入口,脏空气经由其被吸入真空吸尘器,该脏空气入口向下延伸,以使得其面对要被清洁的地板。灰尘分离装置可采取过滤袋的形式,或已知可替换地采取旋风装置。本发明不涉及灰尘分离装置的性质且由此适用于使用任一配置的真空吸尘器。
例如,刷条形式的搅拌器支撑在脏空气入口,以使得其从该入口凸出较小的长度。刷条典型地包括细长的圆柱芯,刷毛在该圆柱芯长度上沿径向延伸。刷条可被专用马达驱动,典型地通过驱动带,以使得刷条在入口内旋转。刷条的旋转导致刷毛拍打来自要被清洁的地毯的纤维的灰尘和碎屑。吸入空气导致空气绕刷条流动和在其之下流动,以帮助灰尘从要清洁的表面升起然后把其从脏空气入口传输到灰尘分离装置。清洁地毯表面时使用搅拌器提供了比不使用搅拌器更好的清洁效果。
使用搅拌器的表面处理设备遇到的问题是搅拌器马达必须被保护以免其在可能遇到不利的运行条件下过热和/或过载。这样的情形例如发生在旋转搅拌器在与毯子边缘或其它物体纠缠时被阻止或限制旋转从而被堵塞的情况下。
发明内容
本发明提供一种开关和马达组件,用于表面处理设备,该组件包括用于驱动搅拌器的马达、设置用于选择性第使搅拌器驱动马达通电的第一开关、可复位断路器和为第一开关和断路器公用的第一致动器,该控制器机械地控制第一开关和断路器,使得当第一开关被启动时该断路器被自动复位。
当用户致动或重新启动搅拌器马达时,控制器自动复位断路器,这大大简化了用户的操作。以前是通过单独的控制器来复位断路器的,该控制器典型地采用组合有马达的设备上安装的用户可操作的按钮的形式。已经发现的是,当断路器操作以使得搅拌器停止运行时,用户直观地开关用于搅拌器驱动马达的开关,以试图复位搅拌器马达。利用本发明的组件,用户自动地复位断路器,由此允许搅拌器被重新通电。该致动器提供了开关和断路器之间的直接机械链接。
优选地,该促动器是用户可操作的按钮的形式,该按钮启动或关闭该开关,同时移动与断路器相关联的柱塞。
还可以提供具有专用开关的第二马达。控制器可被设置,以还控制开关的启动,以使得当用户操作该开关以是第二马达通电时,与搅拌器马达相关联的开关被自动地启动。这个特征防止用户在第二马达被首先通电时忘记是搅拌马达通电。此后,搅拌器马达可被第一开关独立地通电和断电。控制器可被设置以使得当用户使第二马达的开关断电时自动地使得搅拌器马达的开关自动断电。这个特征确保在用户使第二马达断电时搅拌器马达的开关自动地断电。
本发明特别适用于表面处理设备,例如真空吸尘器。在这样的设备中,第二马达可以是主真空马达,其产生用于使灰尘从地板表面升起的吸力。
附图说明
本发明通过示例的方式并参考附图予以说明,其中:
图1是包括根据本发明构造的组件的表面处理设备的侧视图;
图2是处于使用模式中的图1的设备的侧视图;
图3是图1和图2的设备的表面处理头的部分剖切透视图;
图4是形成图1至3的设备的部分的致动器的正视图;以及
图5是形成图1至3的设备的部分的开关和马达组件的示意图。
在整个说明书中相同的参考标号表示相同的部件。
具体实施方式
参考图1和2,表面处理设备以真空吸尘器的形式示出且通常由参考标号1表示。真空吸尘器1包括主体2、用户操作手柄3和一组用于沿地板表面滚动吸尘器的轮子4。在主体2的下端是马达壳,其承装马达5,该马达被设置用于驱动风扇,以产生吸力,以便抽吸流体,例如空气,到吸尘器1内。吸尘器头6以铰链形式(articulated fashion)安装在主体2的下端。
主体2承装分离装置7,该分离装置用于从被马达5驱动的风扇吸入到机器内的脏气流中分离灰尘和其它碎屑。在该实施例中,分离装置7是旋风器,其中灰尘被从气流中旋出。旋风分离装置7包括彼此串联设置的两级旋风分离器。第一级是圆柱壁腔8而第二级包括一组彼此并行设置的锥形的基本上截头锥形的腔9。气流被切向地导入腔8的上部。较大的碎屑和颗粒被旋风分离和收集在腔8内。该气流然后穿过罩(在图3中用参考标号10表示)到达一组较小的截头锥形旋风器腔9。细微的灰尘被这些腔9分离且分离的灰尘被收集在通用收集区域中。第二组分离器9可以是竖立的,即,它们流体入口和出口在顶部且它们的灰尘出口在底部,或相反,即,它们的流体入口和出口在底部而它们的灰尘出口在顶部。灰尘分离装置7的性质对于本发明不是重要的。
主体2还承装过滤器(在这些附图中不可见),用于捕捉已清洁的气流中的细微颗粒。这些过滤器去除任意细微颗粒的灰尘,该灰尘未被分离装置从气流中去除。第一过滤器,其被称为马达前过滤器,被设置在马达和风扇之前。第二过滤器,其被称为马达后过滤器,被设置在马达和风扇之后。在驱动吸气风扇的马达5处具有碳刷,马达后过滤器还用于捕捉由碳刷散发的碳颗粒。清洁的空气然后被排放到大气。
手柄3从主体2的后部向上延伸。当吸尘器1处于图1所示的位置时,其可被用于筒式模式中,其中手柄3可被松脱和用作软管和棒组件。主体2上的切换阀自动地把灰尘分离器7连接到棒和软管组件,以使得吸尘器可被在地板清洁时用于该筒式模式。空气被通过棒的端部抽入到吸尘器,该棒可被从吸尘器松脱以进行适当操作。
当吸尘器1要被用于传统的立式清洁模式中时,用户使用手柄3来使主体2倾斜,如图2所示。吸尘器头6用于在立式清洁模式中处理地板表面,且在图3中更详细地示出。在该实施例中,其包括腔11,用于支撑刷条12形式的搅拌器。腔11的下部面对地板的侧部具有空气入口槽,且刷条12被旋转地安装在腔内,以使得刷条上的刷毛可通过入口槽凸出且可搅动吸尘器头要经过的地板表面。刷条12由位于吸尘器头6内的专用搅拌器驱动马达13旋转地驱动。带和轮系统,其中带14在这些附图中可见,把马达13连接到刷条12以提供驱动力。用户可通过开关来开关主马达5和刷条马达13两者,该开关由用户通过按钮形式的致动器操作,其在图4中示出。按钮15被设置以开关用于使主马达5通电的开关。当按钮15被用户压下时,其锁定在降低位置,如虚线15’所示,以对于用户表示其状态。按钮16被用于控制马达13,该马达13被设置用于驱动搅拌器12。当该按钮被压时,其也锁定在降低位置,如虚线16’所示,以对于用户表示其状态。当吸尘器1被用于清洁地毯时,使用者可选择性地使搅拌器马达13通电,以操作搅拌器12。在使用中,搅拌器12搅动地毯的纤维,由此使灰尘脱离纤维。当吸尘器1被用于清洁硬地板时,或用于筒式模式时,搅拌器可被关闭。按钮15、16可在其上具有可视标识,以表示它们各自的功能。按钮15、16传统地位于彼此靠近的位置,该位置对于用户是容易看见的——在该实施例中,它们位于机器的主体2的顶部,靠近手柄3的基部。
设备中的马达和开关的整体示意图在图5中示出。按钮15被设置以启动开关17,该开关控制主体2中的马达5的通电。类似地,按钮16被设置以启动开关18,该开关控制吸尘器头6中的搅拌器驱动马达13的通电。开关18通过设置在主体2上的所谓的倾斜开关19而被连接到搅拌器驱动马达13。倾斜开关19被设置以检测主体2何时被向后倾斜用于立式清洁,且允许搅拌器马达在吸尘器被立式模式中使用时被选择性地通电。倾斜开关19可被设置以防止搅拌器马达13在其竖立位置时被通电,以防止搅拌器在吸尘器1在筒式模式中使用时被驱动。
还可设置用于搅拌器马达13的断路器20。当吸尘器1被用于立式清洁操作同时搅拌器12被马达13驱动时,搅拌器可被遗留在地板表面上的物体或被毯子边缘阻塞。断路器20确保当发生这样的阻塞时马达13不过热且自身烧掉。当搅拌器12阻塞时,搅拌器马达13引起比平时高的电流。当该电流超过预定数值时,开关20内的双金属元件加热且跳闸,由此关闭搅拌器马达13。用户然后可安全地移除阻塞物。吸尘器头6靠近用于搅拌器的腔11的部分可以是透明的,以使得用户可观察是否存在防止刷条12旋转的阻塞物。
在搅拌器12被马达13再次驱动之前,断路器20需要被复位。这是一个重要的安全特征。根据本发明,当控制搅拌器马达的开关18被启动时,断路器20被复位。这是通过控制器实现的,在该实施例中,该控制器是以对于开关18和断路器20都通用的致动器的形式实现的,该致动器为按钮16。
当按钮16被用户按下时,按钮的底侧上的第一柔性件21启动开关18。同时,也设置在按钮16的底侧上的第二柔性件22压靠柱塞23,该柱塞23复位断路器20。件21和22被设置以使得在件21启动开关18之前第二件22压下柱塞23。件21和22是柔性的,以允许组成该组件的元件中的制造公差。
因此,用户可通过重启搅拌器马达13的动作来复位断路器20。早先,用于复位断路器的致动器独立地位于吸尘器1上,且已知用户难于定位该致动器或明白其用途。在用户清除阻塞物后,用户直觉地通过按压按钮16来重启用于搅拌器马达13的开关18。在此过程中,用户还无意识地重启断路器20,允许马达13重新通电。本发明消除了用于断路器的单独的复位组件的需要。
每次用户启动开关18时,按压按钮16的动作导致断路器20的复位,即使断路器未跳闸。该配置不存在缺点,但是其确保断路器在发生跳闸后可自动复位。
作为另一优点,按钮15和16通过连杆24连接,该连杆24被设置为使得当按钮15被压下以使主马达5通电时,按钮16被同时压靠开关18,由此自动地开关搅拌器13。用户有时忘记在清洁操作中使用搅拌器12,该配置确保了在主马达5被开启时搅拌器自动操作。在该实施例中,连杆24是机械的且是被螺旋弹簧26弹性地偏压的枢转臂25的形式。当按钮15被按压时,按钮的角配合臂25的一个端部,使其向下促动。因此,按钮16也被强制向下移动,由此其锁定在其降低位置。
当主马达5被通电且按钮15、16已锁定到它们的降低位置时,按钮16可被独立地致动,以使得搅拌器马达13可按用户的需要操作或不操作。连杆机构24的臂25在弹簧26的力的作用下枢转,以允许按钮16运动到升高和降低位置。臂25自己不会影响按钮15的运动。
当用户完成清洁操作时,他按压按钮15以关闭开关17且使主马达5断电。由于按钮15返回其升高位置,连杆24动作以使按钮16促动到其原始位置,以使得开关18被关闭。因此,当主马达5被断电时,搅拌器马达13也被自动断电。该特征确保搅拌器马达13在清洁操作之后不被用户意外地留在开启状态。
尽管本发明是参考立式吸尘器说明的,其还适用于筒式吸尘器,其具有位于棒和软管组件端部的表面处理头。吸尘器头还可以以地板工具的形式提供,其可安装到任一类型的真空吸尘器的棒和软管组件的端部。
当然,可采用其它变体而不离开本发明的范围。例如,尽管与搅拌器马达开关和断路器相联的控制器已在所示的实施例中实现为用户可操作的按钮,该联结可替换为电或甚至软件形式实现。类似地,用于马达开关的致动器15、16之间的连杆还可被电气地设置或通过软件控制。
尽管这些开关被示出为物理地电连接到它们各自的马达,无线信号可被用于开关马达。
还可提供用于主马达5的断路器,以防止马达过热。还可设置用于控制主马达开关通电的致动器,以自动地致动第二断路器以使其复位。
尽管所示的实施例示出了真空吸尘器,其中用管道传输气流,应明白,本发明可用于传输其它流体,例如水和清洁剂的真空吸尘器。
