Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a floor brush and a vacuum cleaner that can keep cooling performance of an electric motor for a long period.SOLUTION: A floor brush 24 comprises a case body 31, a filter 54, an electric motor 38, and a filter cleaning part 63. The case body 31 comprises a suction port, an electric motor chamber 48, and an opening part 35. The suction port is opened in a lower part opposed to a floor surface. The electric motor chamber 48 communicates with the suction port. The opening part 35 is opened in a location other than the lower part, and communicates with the electric motor chamber 48. The filter 54 is arranged so as to cover the opening part 35. The electric motor 38 is housed in the electric motor chamber 48, and generates heat by being energized. The filter cleaning part 63 removes dust attached to the filter 54.SELECTED DRAWING: Figure 1
【課題】電動機の冷却性能を長期維持できる床ブラシおよび電気掃除機を提供する。【解決手段】床ブラシ24は、ケース体31と、フィルタ54と、電動機38と、フィルタ清掃部63とを有する。ケース体31は、吸込口と、電動機室48と、開口部35とを備える。吸込口は、床面に対向する下部に開口される。電動機室48は、吸込口と連通する。開口部35は、下部を除く位置に開口され電動機室48と連通する。フィルタ54は、開口部35を覆って配置される。電動機38は、電動機室48に収容され、通電によって発熱する。フィルタ清掃部63は、フィルタ54に付着した塵埃を除去する。【選択図】図1 |
