作業者は、電源コードを壁面などのコンセントに接続した後、把持部28を把持し、所望の設定ボタン29を操作することにより、本体制御部を介して電動送風機18を所望の動作モードで起動させる。この電動送風機18の駆動により、負圧が集塵部、本体吸込口19、ホース体21、延長管22および床ブラシ23の吸込口71および吸気口68，74へと順次作用する。したがって、床ブラシ23を床面上に載置した状態で、吸気風が形成され、この吸気風が、各吸引口45から第１ないし第３の収容部55〜57(ブラシ収容部44)へと後方に向けて吸い込まれ、第１ないし第３の毛ブラシ部79，88，97に吹き付けられて、第１ないし第３の回転ブラシ61〜63を一体的に回転させる。
After connecting the power cord to an outlet such as a wall, the operator grips the grip portion 28 and operates the desired setting button 29 to start the electric blower 18 in a desired operation mode via the main body control portion. Let By driving the electric blower 18, negative pressure sequentially acts on the dust collection unit, the main body suction port 19, the hose body 21, the extension pipe 22, and the suction port 71 and the suction ports 68 and 74 of the floor brush 23. Therefore, in the state where the floor brush 23 is placed on the floor surface, an intake air is formed, and this intake air is sent from each suction port 45 to the first to third accommodation parts 55 to 57 (brush accommodation part 44). And sucked back and sprayed onto the first to third bristle brush portions 79, 88, 97 to integrally rotate the first to third rotating brushes 61 to 63.
そして、作業者は、床ブラシ23を床面上で前後に走行させることで、第１ないし第３の回転ブラシ61〜63の第１ないし第３の毛ブラシ部79，88，97によって床面の塵埃を掻き出しつつ、吸込口71および吸気口68，74から吸い込む。このとき、第１ないし第３の毛ブラシ部79，88，97は、各ブラシ台毛ブラシ部81，91，101が床面の塵埃を掻き出すとともに、各直毛部82a，92a，93a，102aが直下の床面の塵埃を掻き出し、かつ、各傾斜毛部82b，92b，93b，102bが回転ブラシ61〜63の連結部である軸受部53(軸受体64)の位置の下側の床面の塵埃を掻き出す。したがって、第１ないし第３の毛ブラシ部79，88，97は、ブラシ収容部44の一側から他側に亘って、すなわち一方の連通口51から他方の連通口51に亘るケース体31の左右幅方向全体の床面の塵埃を、死角を作ることなく全体に亘って掻き出すことができる。なお、各傾斜毛部82b，92b，93b，102bは、軸受部53の先端側の傾斜部67，67によって左右に掻き分けられるため、各ブラシ台毛ブラシ部81，91，101の軸受部53側に傾斜した部分、および、各傾斜毛部82b，92b，93b，102bが他部との接触などで摩耗することがない。
Then, the operator causes the floor brush 23 to run back and forth on the floor surface, so that the first to third bristle brush portions 79, 88, and 97 of the first to third rotating brushes 61 to 63 cause the floor surface. The air is sucked in through the suction port 71 and the suction ports 68 and 74 while scraping out the dust. At this time, the first to third bristle brush portions 79, 88, 97 have the brush head bristle brush portions 81, 91, 101 scraping off dust on the floor surface and the straight hair portions 82a, 92a, 93a, 102a. Scrapes the dust on the floor immediately below, and the lower floor surface of the position of the bearing portion 53 (bearing body 64) where each inclined bristle portion 82b, 92b, 93b, 102b is a connecting portion of the rotating brushes 61-63 Scrape out dust. Accordingly, the first to third bristle brush portions 79, 88, and 97 are formed from one side of the brush housing portion 44 to the other side, that is, from the one communication port 51 to the other communication port 51. Dust on the entire floor surface in the left-right width direction can be scraped out without creating a blind spot. Each inclined bristle portion 82b, 92b, 93b, 102b is scraped to the left and right by the inclined portions 67, 67 on the distal end side of the bearing portion 53, so that the brush base bristle brush portions 81, 91, 101 have the bearing portion 53 side. And the inclined hair portions 82b, 92b, 93b, 102b are not worn by contact with other portions.
そして、吸込口71から吸い込まれた吸気風は、塵埃とともに吸込風路72へと流れ、吸気口68，74から吸い込まれた吸気風は、連通風路75を介して塵埃とともに吸込風路72へと流れる。そして、この吸込風路72を通過した吸気風は、接続管32、延長管22、ホース体21、本体吸込口19を介して集塵部へと吸い込まれ、集塵部において塵埃が分離捕集される。また、塵埃が捕集された吸気風は、電動送風機18へと吸い込まれ、この電動送風機18を冷却した後、排気されて排気風となり、掃除機本体12の外部へと排気される。
Then, the intake air sucked from the suction port 71 flows to the suction air passage 72 together with dust, and the intake air sucked from the intake ports 68 and 74 flows to the suction air passage 72 together with dust via the communication air passage 75. And flow. Then, the intake air that has passed through the suction air passage 72 is sucked into the dust collecting part through the connecting pipe 32, the extension pipe 22, the hose body 21, and the main body suction port 19, and the dust is separated and collected in the dust collecting part. Is done. Further, the intake air in which the dust is collected is sucked into the electric blower 18, and after cooling the electric blower 18, it is exhausted to become exhaust air and exhausted to the outside of the cleaner body 12.

Therefore, the dust in the vicinity of the bearing portions 53 and 53 can be reliably sucked regardless of the turbulent flow in the brush housing portion 44 or the obstruction of the air flow by the bearing portions 53 and 53.
さらに、第１ないし第３の回転ブラシ61〜63の各傾斜毛部82b，92b，93b，102bを、軸受部53，53を覆うように傾斜状に突出させることにより、軸受部53，53の下側に位置する床面の塵埃を、これら各傾斜毛部82b，92b，93b，102bによって、より確実に掻き出すことができる。
Further, the inclined bristle portions 82b, 92b, 93b, and 102b of the first to third rotating brushes 61 to 63 protrude in an inclined manner so as to cover the bearing portions 53 and 53. The dust on the floor located on the lower side can be more reliably scraped out by the inclined hair portions 82b, 92b, 93b, 102b.
また、各軸受部53の下端側を左右方向に接近させるように傾斜させた傾斜部67，67とすることにより、第１ないし第３の回転ブラシ61〜63の各傾斜毛部82b，92b，93b，102bを左右に掻き分け、回転ブラシ61〜63の回転時の負荷を低減できるとともに、第１ないし第３の回転ブラシ61〜63の各傾斜毛部82b，92b，93b，102bが他部と接触して摩耗することがなく、さらに、軸受体64への塵埃の付着およびこの付着により生じる例えば回転停止(ロック)などの不具合を抑制できる。
In addition, the inclined bristle portions 82b and 92b of the first to third rotating brushes 61 to 63 are formed by tilting the lower end sides of the respective bearing portions 53 so as to approach the left and right directions. 93b and 102b are divided into left and right to reduce the load during rotation of the rotating brushes 61 to 63, and the inclined bristle portions 82b, 92b, 93b and 102b of the first to third rotating brushes 61 to 63 are connected to the other parts. Further, there is no contact and wear, and it is possible to suppress problems such as dust adhesion to the bearing body 64 and rotation stoppage (lock) caused by this adhesion.
そして、上記床ブラシ23を備えることにより、床面の広い範囲を効率よく掃除できる電気掃除機11を提供できる。
By providing the floor brush 23, it is possible to provide the electric vacuum cleaner 11 that can efficiently clean a wide range of the floor surface.
なお、上記各実施形態において、電気掃除機11としては、キャニスタ型に限らず、縦長の掃除機本体12の下部に床ブラシ23が接続された、アップライト型の電気掃除機などでも対応して用いることができる。
In each of the above-described embodiments, the vacuum cleaner 11 is not limited to the canister type, and an upright type vacuum cleaner in which a floor brush 23 is connected to the lower part of the vertically long vacuum cleaner body 12 can be used. Can be used.
そして、本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。
And although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
