本発明は被掃除面に附着した塵埃を除去する回
転ブラシを具備した電気掃除機に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner equipped with a rotating brush for removing dust attached to a surface to be cleaned.
従来例の構成とその問題点
従来より、被掃除面に附着した塵埃を被掃除面
から分離する回転ブラシを具備した電気掃除機が
知られている。Conventional Structure and Problems There have been conventionally known vacuum cleaners equipped with a rotating brush that separates dust adhering to the surface to be cleaned from the surface to be cleaned.
その構成を第１図にもとづいて説明すると、図
において、１は掃除機本体で、この掃除機本体１

ー１０の下方に構成された集塵室１１に吸い込ま
れる。 The structure will be explained based on FIG. 1. In the figure, 1 is a vacuum cleaner main body;
An electric blower 2 is installed inside. Reference numeral 3 designates a floor nozzle, inside which a rotary brush 4 is rotatably supported by a bearing 5, and the rotary brush 4 is rotated by a rotary brush electric motor 6 and a belt 7. The dust separated from the surface to be cleaned by the rotating brush 4 is sucked into a dust collection chamber 11 configured below a filter 10 through a suction port 8 and a suction passage 9.
しかしながら、上記のような構成では、電動送
風機と回転ブラシ用電動機の２つの電動機がある
ため、重量が重くなりコストも高くなる。また回
転ブラミ用電動機を収納するため、床ノズルが大
きくなるという欠点を有していた。 However, in the above configuration, since there are two electric motors, an electric blower and a rotary brush electric motor, the weight is heavy and the cost is also high. Another disadvantage is that the floor nozzle becomes large because it accommodates the electric motor for the rotating brush.
また、電動送風機を掃除機本体底部に内設し

機もあるが、この場合、電動送風機の位置が回転
ブラシ駆動のために掃除機本体底部に定まつてし
まい、そのため構成的には吸込口から集塵室まで
ホースで接続し上から下へ、吸引しなければなら
ず、距離が長く損失が大きいものであつた。 There are also vacuum cleaners that have an electric blower built into the bottom of the vacuum cleaner and drive a rotating brush with the electric blower, but in this case, the position of the electric blower is fixed at the bottom of the vacuum cleaner to drive the rotating brush. Therefore, it was necessary to connect the suction port to the dust collection chamber with a hose and suction from the top to the bottom, which resulted in a long distance and a large loss.
発明の目的
本発明は上記欠点に鑑み、１つの電動機で送風
