具体实施方式
以下使用附图说明本发明的实施例。图1中，1是筒状体，2是在筒状体1的外圆周面上呈V字形地植毛的刷，由这两者构成旋转刷。另外，根据目的和用途代替刷状还可以是薄板状的搅拌件和擦拭件等。另外，还可以通过把刷状的搅拌件，薄板状的搅拌件，擦试件进行适当组合构成旋转刷。3是构成减速机构的减速齿轮架，4是支撑安装在筒状体1内的电机的电机架，5是碳刷，6是第1开口，是设置在筒状体1的外周的通气用的通孔。第1开口6形成在筒状体1的端部圆周面上，设置在与安装电机架4的筒状体1的端部相反一侧的端部上。32是设置在电机架4上的通气用的第2开口。刷或搅拌件2的植设不限于V字形也可以通过采用螺旋形等提高集尘搅拌效果。图2中，7是电机的转子，8是电机的定子，该定子8安装在电机架4的内表面上，配置成与转子7的圆周面之间设置间隙。9是转子轴，与转子7成一体地旋转。10是整流子，该整流子10安装在转子7的端部，而且在其圆周面上滑动接触碳刷5，经过碳刷5、整流子10向转子7供电。11是第1轴承，其内环中压入电机架4的外周，外环压入到筒状体1的左端(电机侧的端部)的内周，旋转自由地支撑筒状体1的电机一侧。碳刷5设置在第1轴承11的外侧，即从筒状体1的电机一侧的端部向外侧突出的电机架4的一部分上。在碳刷5上进行用于供电的布线，通过配置在旋转的筒状体1的外侧，使得能够进行良好布线作业。另外，磨损了的碳刷的交换作业也很容易。12是设置在电机架4右侧面(与碳刷5相反一侧的端部)的第3开口，能够进行向电机内的外气流通，谋求电机的冷却。13是第2轴承，压入到减速齿轮架3中，用其内环支撑转子轴9的右端(与电机相反一侧的端部)。14是第3轴承，外环压入到筒状体1的一部分(筒状体1的与电机相反一侧的侧面的凹部)，在其内环中压入转子轴9。15是第1齿轮，固定在转子轴9上用第2轴承13和第3轴承14夹住其左右两侧。16是第2齿轮，支撑设置在减速齿轮架3上的轴17，使得第1齿轮15的旋转传递到形成在筒状体1内周侧的第3齿轮18，对筒状体1进行减速驱动。19是设置在转子7两侧的电机轴承，由电机架4支撑。通过这样的结构，即使采用减速齿轮机构筒状体1也能够用第1轴承11和第3轴承14支撑，以高精度得到平稳的旋转，极少产生噪声。另外，如果用导磁性材料形成筒状体1，则能够进一步提高电机的效率。能够在筒状体1的两个端部平衡地配置作为重物的电机和减速齿轮以及其托架，在使筒状体1旋转的情况下由于重量平衡良好因此难以发生旋转振动，而且由于重物靠近端部即轴承侧因此很少发生旋转振动。20是检测装置，检测吸引通路内的压力或者电机的温度或者流过电机的电流，如果检测的压力，温度，电流异常，则切断对于电机的通电，是电机保护或者防止发热的安全装置。例如，在旋转刷挂住了垃圾等成为不动的状态下，电机的温度或者流过电机的电流过大，通过检测到该异常能够进行电机保护，防止发热。另外，为了冷却电机利用了吸引风(后述)，而根据通路(可以是吸引通路)内的压力来检测配置在吸尘器主体的集尘室(图10的48)中的过滤器网眼堵塞等导致的吸引风的吸引力的降低，一旦压力下降电机的冷却不充分，则切断对于电机的通电，也能够防止发热。21是外气导入室，用于向设置在筒状体1上的第1开口6的外气的连通。22是地面吸嘴，在该地面吸嘴22内配置旋转刷。23是软管，软管23的一端连接在设置到地面吸嘴22的后方的吸引口38上，与倾斜自由地安装在地面吸嘴22的后方的吸尘器主体内的集尘室48，吸引用电送风机43(参考图10)相连通。27是在地面吸嘴22的主体内突出设置的，并包围筒状体1的两个端部的隔板，其把吸引用电送风机的吸引力作用的吸入室28，设置在筒状体1的端部的第1开口6所在的外气导入室21以及设置在电机架4上的第2开口32隔离的同时，通过在第2开口32一侧的隔板27的一部分上开口的连接口27a可以得到吸入室28中的吸引作用。即，通过吸引作用使外气通过外气导入室21，第1开口6，筒状体1内，电机架4内，第2开口32，进行电机的冷却。本实施例中记述了具有两条软管23的图面，而在软管23是一条的情况下，通过在第2开口32一侧的隔板27的一部分上开口的连接口27a与吸入室28相连通则在第2开口32上吸引力直接作用，将提高电机冷却效果。这种情况下，吸引口38和连接口7a相互靠近，可以得到吸引口38的强有力的吸引力。另外，在软管23是一条的情况下如果使得软管23位于在第2开口32一侧的隔板27的一部分上开口的连接口27a的相反一侧上，则通过第2开口32从连接口27a吸引的空气在吸入室28内沿横向移动，高效地把通过刷2收集的尘埃移送到软管23。使软管23位于该连接口27a的相反一侧，而在地面吸嘴22的宽度方向把吸引口38和第1开口6设置在相同一侧。另外，旋转刷位于吸入室28内，在与该旋转刷的下方对应的地面吸嘴22的底部上设置开口45，使得旋转刷与地面一侧相对。
图3中由于把碳刷5收容在筒状体1内采用更紧凑的结构，因此能够更有效地利用地面吸嘴22的宽度或者进一步小型化。另外，图3示出代替减速机构进行直接驱动的同时，作为用于在筒状体1内向电机内部送风获得冷却效果的装置，在转子轴9上设置风扇A24，或者使风扇B25向筒状体内周突出以及使风扇C26向筒状体1的侧壁突出的情况。根据冷却效果，各风扇A24，B25，C26既可以单独设置也可以组合起来设置。图4作为检测装置示出使用了手动恢复型热敏保护装置29的情况，30是其热敏部分，31是手动恢复按钮。从而，在使用过程一旦发生温度上升等异常情况则自动停止，然后，即使在温度自然下降后也不能够再次开始动作，在确认并消除了异常原因后必须操作手动恢复按钮31。由此，使得只能通过手动开始再次动作。
图5示出把外齿轮型电机安装在内部的旋转刷装置，与图3相比较最大的不同点在于在筒状体1的内周嵌入由磁铁组成的转子33，在用地面吸嘴22支撑固定两个端部的电机轴35上固定定子34，通过把定子座36的外周压入到内环的第1轴承11的外环上旋转自由地支撑筒状体的左端，在筒状体1的右端经过轴承37旋转自由地支撑筒状体1的侧壁。38是用于从地面吸嘴22的吸入室28通过软管23吸入空气的吸引口。本实例中示出使用了两条软管23的情况，但也可以使用一条，这时的吸引口是在单侧的一个。
图6中，39是设置在地面吸嘴22的上面的外气取入口。设置外气取入口39的部分对应于用隔板27与吸入室28隔离的外气导入室21的空间F(参照图2)，另一方面设置在电机架4上的第2开口32与把外气取入口39和相反一侧的吸入室28隔离开的空间E相对。该空间E的隔板27的一部分上由于设置着连通图7a所示的吸入室28的连接口27a，所以如果吸引用的电送风机43的吸引力作用到吸入室28中，则在连接口27a上吸引力产生作用，接着，吸引力对于第2开口32，筒状体1内，第1开口21，空间F产生作用，从外气取入口39取入外气。而且，使用该被取入的外气冷却电机。图7(a)中，42是清扫地面。另外，如图7(b)所示，在对应于空间E的地面吸嘴22的主体底面上设置凹部40，通过在该凹部40中设置连通空间E以及吸入室28的开口41，吸入室28的吸引力在空间E中作用，产生箭头所示那样的空气的流路，如上所述可以进行电机冷却。这种情况下，还能够把凹部40所处的地面的尘埃一起吸引到吸入室28一侧。另外，通过把外气取出口39设置在地面吸嘴的上面，能够抑制吸入由旋转刷拢起的尘埃，能够在冷却风内不混入尘埃，进行电机的冷却。在图8、9中，G是把集尘室48以及电送风机43安装在内部的吸尘器主体，把其下部倾斜自由地安装在地面吸嘴22的后部。
图10中，43是吸引用的电送风机，44是位于集尘室48内的集尘袋，45是设置在地面吸嘴22的底面上的吸尘吸入口，46是设置在地面吸嘴22内的旋转刷。该地面吸嘴以及旋转刷采用图1至图7所示的装置。图11中，46a是螺旋状植毛的旋转刷，47是设置在吸入口45的左右侧的刷体，固定着具有方向性地植毛了的刷状体，在这里也能够拾取线头等。
另外，实施例中使用了一个旋转刷，但也可以是具有多个的旋转刷装置。
图12(a)中，46是上述各实施例的旋转刷，49是作为具备了本发明的旋转刷装置的电设备的吸尘器，在前后各具有1对行走用轮54。50是地面接触用轮，设置在用弹簧51压向下方的调节器52的下端，通过地面检测动作而上升，闭合原来为断开状态的开关53使得安装在旋转刷装置内部的电机动作。42是地面。图12(b)示出检测敷设在地面42上的地毯55，开关53成为接通状态的情况。图12(c)示出其电路，57是电源，53是检测开关，56是安装在旋转刷装置内部的电机，58是后述的电机旋转控制用的可变电阻器。由于这样的结构，因此地毯用的吸尘器能够在地毯55上当地面接触轮50被上压时进行动作。
图13(a)中，59是由地面吸嘴22倾斜自由地轴支撑的操作件，在垂直状态下直立时把开关60断开，切断对旋转刷装置的通电。61是设置在操作件59上的操作单元，操作上述的可变电阻器58控制旋转刷46的旋转速度。62是设置在吸尘器48中的过滤器，捕集用旋转刷46拢起的尘埃。63是由发光，感光元件等组成的尘埃检测装置，根据吸入到集尘室48中的尘埃通过时的感光元件的输出变化进行检测，根据尘埃的量使旋转刷46的旋转速度变化。图13(b)示出其电路，64是相位控制装置，根据上述尘埃检测结果进行电机56的旋转速度的控制。相位控制装置64根据操作单元61中的设定如果选择了基于尘埃检测的速度设定，则进行上述的控制，而为了使得使用者能够任意选择转数，还可以进行与基于尘埃检测的旋转速度设定不同的高·中·低的旋转速度设定。
通过这样的结构能够提高使用操作性，进行电力利用率高的清扫。
