Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an electric cleaner which enables reducing a noise of an electric fan.SOLUTION: There are provided: an electric fan chamber 8 having an electric fan 7 therein with an air inlet 7a; a dust chamber 10 for collecting dust; a separation wall 11 that is provided between the electric fan chamber 8 and the dust chamber 10 and having a first opening 11a communicating with the electric fan chamber 8 and the dust chamber 10; a fixing frame body 12 provided between the dust chamber 10 and the separation wall 11 and having a second opening 12a communicating with the first opening 11a; and a filter member 13 covering an upstream-side of the first opening 11a. The fixing frame body 12 includes a substantially-circular first wall 27 formed concentric with a center axis of the electric fan 7. The first wall 27 is configured to be larger than the diameter of the air inlet 7a of the electric fan 7, thereby reducing a sonic wave delivered from the electric fan 7 to the duct chamber 10 and reducing a noise of the electric cleaner.
【課題】電動送風機の騒音を低減できる電気掃除機を提供すること。【解決手段】吸気口7aを有した電動送風機7を内蔵する電動送風機室8と、塵埃を捕集する集塵室10と、電動送風機室8と集塵室10との間に配置され、電動送風機室8と集塵室10とを連通する第1の開口部11aを有する分離壁11と、集塵室10と分離壁11との間に配置され、第1の開口部11aと連通する第2の開口部12aを有する固定枠体12と、第1の開口部11aの上流側を覆うフィルタ部材13とを備え、固定枠体12には、電動送風機7の中心軸と同心に形成された略円形状の第1の壁27が設けられ、第1の壁27は電動送風機7の吸気口7aの直径以上に構成したことで、電動送風機7から集塵室10に伝達する音波の量を軽減でき電気掃除機の騒音を低減することができる。【選択図】図4 |
