　以下、本発明に係る電気掃除機の実施形態について説明する。 Hereinafter, embodiments of the vacuum cleaner according to the present invention will be described.
　先ず、吸込口体は、電気掃除機の使用状態における可搬性、操作の容易性を考慮すると、その大きさおよび重さ（質量）に制約が生じる。この制約のため、回転清掃体の原動機であるタービンおよび電動機は、その体積（占有容積）や重さが制限される。 First, considering the portability of the vacuum cleaner in use and the ease of operation, the size and weight (mass) of the suction port body are limited. Due to this restriction, the volume (occupied volume) and weight of the turbine and electric motor that are the prime movers of the rotary cleaning body are limited.
　そこで、特許文献１の吸込口体は、タービンの出力を極力大きく得るため、タービンの回転軸を回転清掃体の回転軸に対して直交させて配置し、タービンの回転半径を極力大きく確保する。 Therefore, in order to obtain the output of the turbine as much as possible, the suction port body of Patent Document 1 is arranged with the rotating shaft of the turbine orthogonal to the rotating shaft of the rotary cleaning body to ensure the maximum rotating radius of the turbine.
　しかしながら、特許文献１の吸込口体は、タービンから回転清掃体にトルクを伝達するため、複数の歯車からなる減速機構や、複数のタイミングベルト、かさ歯車などの機構からなる伝達機構を必要とする。この伝達機構は、摩擦部分や摺動部分が多く、機械的損失が大きくなる。 However, since the suction port body of Patent Document 1 transmits torque from the turbine to the rotary cleaning body, it requires a transmission mechanism consisting of a speed reduction mechanism consisting of a plurality of gears and a mechanism such as a plurality of timing belts and bevel gears. . This transmission mechanism has many frictional portions and sliding portions, and increases mechanical loss.
　また、タービンを原動機とする回転清掃体を備えた吸込口体は、電動送風機の吸引力の一部を流用してタービンを駆動させるため、電気掃除機の吸込仕事率を低下させない範囲で十分なトルクを得ることが難しい。例えば、タービンを原動機とする回転清掃体を備えた吸込口体は、カーペットが敷かれた被掃除面において、回転清掃体を駆動させることが困難な場合がある。 Moreover, since the suction port body provided with the rotary cleaning body which uses a turbine as a prime mover drives the turbine by using a part of the suction force of the electric blower, it is sufficient in a range that does not reduce the suction work rate of the vacuum cleaner. It is difficult to obtain torque. For example, in a suction port body including a rotary cleaning body that uses a turbine as a prime mover, it may be difficult to drive the rotary cleaning body on a surface to be cleaned on which a carpet is laid.
　そこで、本発明に係る実施形態は、タービンを原動機とする回転清掃体を備え、電気掃除機の吸込仕事率を低下させることなく、回転清掃体を高トルクで駆動可能な回転清掃体ユニット、吸込口体および電気掃除機を提案する。 In view of this, an embodiment according to the present invention includes a rotary cleaning body having a turbine as a prime mover, and a rotary cleaning body unit capable of driving the rotary cleaning body with high torque without reducing the suction power of the vacuum cleaner.

　図４は、本発明の実施形態に係る吸込口体の遊星歯車機構を簡易的に示した側面図である。 FIG. 4 is a side view schematically showing the planetary gear mechanism of the suction port body according to the embodiment of the present invention.
　図４に示すように、吸込口体２６の遊星歯車機構４３は、太陽歯車５１に接続されたタービンシャフト４２を入力軸とし、キャリア５４に一体的に保持された回転清掃体４４（より詳しくは、軸体５８）を出力軸とする減速機構である。遊星歯車機構４３は、回転軸Ｃから見て内側から太陽歯車５１と、遊星歯車５２と、内歯車５３と、を備える。 As shown in FIG. 4, the planetary gear mechanism 43 of the suction port body 26 has a turbine shaft 42 connected to the sun gear 51 as an input shaft, and a rotary cleaning body 44 (more specifically, held integrally with a carrier 54). , A speed reduction mechanism using the shaft body 58) as an output shaft. The planetary gear mechanism 43 includes a sun gear 51, a planetary gear 52, and an internal gear 53 from the inside as viewed from the rotation axis C.

　次に、本実施形態に係る電気掃除機１の動作を説明する。 Next, the operation of the vacuum cleaner 1 according to this embodiment will be described.
　電気掃除機１のユーザは、先ず、掃除機本体２に管部３、すなわち集塵ホース２１と延長管２５と吸込口体２６とを適宜の順序で接続する。 First, the user of the vacuum cleaner 1 connects the pipe portion 3, that is, the dust collecting hose 21, the extension pipe 25, and the suction port body 26 to the vacuum cleaner body 2 in an appropriate order.
　次に、掃除機本体２から電源コード１１を引き出し、商用電源を供給するコンセント（図示省略）に電源プラグ１４を接続する。 Next, the power cord 11 is pulled out from the cleaner body 2, and the power plug 14 is connected to an outlet (not shown) for supplying commercial power.
　次に、電気掃除機１のユーザは、把持部２３を把持して起動スイッチ２４ｂを操作する。 Next, the user of the vacuum cleaner 1 grips the grip portion 23 and operates the start switch 24b.
　そうすると、制御部９は、起動スイッチ２４ｂで設定された動作モードに従い電動送風機８を駆動させる。電動送風機８の駆動によって掃除機本体２と管部３とに負圧が生じ、電気掃除機１は吸込口体２６の吸気口３８および塵埃吸込口３９から空気を吸い込む。 Then, the control unit 9 drives the electric blower 8 according to the operation mode set by the start switch 24b. By driving the electric blower 8, a negative pressure is generated in the vacuum cleaner main body 2 and the pipe portion 3, and the vacuum cleaner 1 sucks air from the suction port 38 and the dust suction port 39 of the suction port body 26.
　次いで、電気掃除機１のユーザは、吸込口体２６を被掃除面に配置し、把持部２３を把持したまま手元操作管２２および延長管２５を前後に往復動させる。 Next, the user of the vacuum cleaner 1 places the suction port body 26 on the surface to be cleaned, and reciprocates the hand operation tube 22 and the extension tube 25 back and forth while holding the grip portion 23.
　そうすると、吸込口体２６は、被掃除面上を前後に往復走行しつつ被掃除面の塵埃を空気とともに（含塵空気）、塵埃吸込口３９から吸い込む。塵埃吸込口３９から吸い込まれた含塵空気は、接続管３２を通って掃除機本体２へと案内される。 Then, the suction port body 26 sucks dust from the surface to be cleaned together with air (dust-containing air) from the dust suction port 39 while traveling back and forth on the surface to be cleaned. Dust-containing air sucked from the dust suction port 39 is guided to the cleaner body 2 through the connection pipe 32.
　このとき、吸込口体２６は、吸気口３８からも空気を吸い込む。吸気口３８から吸い込まれた空気は、タービン４１、４１Ａの案内翼部４６によって動翼部４７に導かれ、動翼部４７を回転させつつ通り過ぎ、吸込室３６内で塵埃吸込口３９から吸い込まれた含塵空気と合流して接続管３２に至る。動翼部４７の回転は、タービンシャフト４２を介して遊星歯車機構４３に入力され回転清掃体４４を駆動させる。この回転清掃体４４の駆動によって、吸込口体２６は、被掃除面上の塵埃を掃き上げるとともに被掃除面を磨く。回転清掃体４４によって掃き上げられた塵埃は、塵埃吸込口３９から吸込口体２６に吸い込まれる。このとき、補助吸気口６０から吸込室３６へ吸い込まれる空気Ｆの流れは、回転清掃体４４の清掃体５９に吹き付けられて回転清掃体４４の回転を補助する。 At this time, the suction port body 26 also sucks air from the suction port 38. The air sucked from the intake port 38 is guided to the moving blade portion 47 by the guide blade portion 46 of the turbines 41 and 41A, passes through while rotating the moving blade portion 47, and is sucked from the dust suction port 39 in the suction chamber 36. It joins the dust-containing air and reaches the connecting pipe 32. The rotation of the moving blade portion 47 is input to the planetary gear mechanism 43 via the turbine shaft 42 to drive the rotary cleaning body 44. By driving the rotary cleaning body 44, the suction port body 26 sweeps up dust on the surface to be cleaned and polishes the surface to be cleaned. The dust swept up by the rotary cleaning body 44 is sucked into the suction port body 26 from the dust suction port 39. At this time, the flow of the air F sucked into the suction chamber 36 from the auxiliary intake port 60 is blown to the cleaning body 59 of the rotary cleaning body 44 to assist the rotation of the rotary cleaning body 44.
　吸込口体２６に吸い込まれた含塵空気は、延長管２５、手元操作管２２および集塵ホース２１を順次に通過した後、掃除機本体２に案内される。 The dust-containing air sucked into the suction port body 26 sequentially passes through the extension pipe 25, the hand operation pipe 22 and the dust collection hose 21, and is then guided to the cleaner body 2.
　掃除機本体２に案内された含塵空気は、塵埃分離集塵部７に吸い込まれて塵埃と空気とに分離される。分離された塵埃は、塵埃分離集塵部７に捕集される。他方、分離された空気は、塵埃分離集塵部７を通過して電動送風機８に吸い込まれ、掃除機本体２から排気される。 The dust-containing air guided to the vacuum cleaner body 2 is sucked into the dust separation and collection unit 7 and separated into dust and air. The separated dust is collected by the dust separation and collection unit 7. On the other hand, the separated air passes through the dust separation and collection unit 7 and is sucked into the electric blower 8 and is exhausted from the cleaner body 2.
　このようにして電気掃除機１は、吸込口体２６から吸い込んだ塵埃を捕集する。 Thus, the vacuum cleaner 1 collects the dust sucked from the suction port body 26.
　本実施形態に係る回転清掃体ユニット３３、３３Ａ、吸込口体２６および電気掃除機１は、回転清掃体４４の回転径とタービン４１、４１Ａの直径を同程度に構成して、タービン４１、４１Ａ（より詳しくは動翼部４７）とタービンシャフト４２と太陽歯車５１の回転中心である駆動軸、遊星歯車５２の公転中心（すなわちキャリア５４の回転中心）である従動軸、および回転清掃体４４の回転中心を略同一直線上（回転軸Ｃ）に配置させることが可能になり、タービン４１、４１Ａから回転清掃体４４にトルクを伝達する際に摩擦や摺動による機械的損失を生じる要素を極力少なくすることができる。具体的には、この機械的損失は、ほぼ遊星歯車機構４３の機械的損失に依存することとなり、回転清掃体４４を駆動させる機構全体の損失の低減を容易に図ることができる。 The rotary cleaning body units 33 and 33A, the suction port body 26, and the electric vacuum cleaner 1 according to the present embodiment are configured so that the rotational diameter of the rotary cleaning body 44 and the diameter of the turbines 41 and 41A are approximately the same, and the turbines 41 and 41A are configured. (More specifically, the rotor blade portion 47), the drive shaft that is the rotation center of the turbine shaft 42 and the sun gear 51, the driven shaft that is the revolution center of the planetary gear 52 (that is, the rotation center of the carrier 54), and the rotary cleaning body 44 It becomes possible to arrange the rotation centers on substantially the same straight line (rotation axis C), and elements that cause mechanical loss due to friction or sliding when transmitting torque from the turbines 41 and 41A to the rotary cleaning body 44 as much as possible. Can be reduced. Specifically, this mechanical loss substantially depends on the mechanical loss of the planetary gear mechanism 43, and the loss of the entire mechanism for driving the rotary cleaning body 44 can be easily reduced.
　また、本実施形態に係る回転清掃体ユニット３３、３３Ａ、吸込口体２６および電気掃除機１は、タービン４１、４１Ａが発生させるトルクが回転清掃体４４を直接駆動させるには足りない場合であっても、同容量（容積）に組み込み可能な平歯車やかさ歯車からなる減速機に比べて比較的に大きい減速比を有する遊星歯車機構４３を備えるため、カーペットが敷かれた摩擦係数の高い被掃除面においても回転清掃体４４を確実に駆動可能なトルクを得ることができる。 Further, the rotary cleaning body units 33 and 33A, the suction port body 26, and the electric vacuum cleaner 1 according to the present embodiment are cases where the torque generated by the turbines 41 and 41A is not sufficient to directly drive the rotary cleaning body 44. However, since the planetary gear mechanism 43 having a relatively large reduction ratio as compared with a reduction gear composed of a spur gear or a bevel gear that can be incorporated in the same capacity (volume) is provided, the carpet is laid and the cleaning coefficient is high. Also on the surface, a torque that can reliably drive the rotary cleaning body 44 can be obtained.
　さらに、本実施形態に係る回転清掃体ユニット３３Ａは、タービン４１、タービンシャフト４２、遊星歯車機構４３および回転清掃体４４を単一のモジュールとして構成することで取り扱いの利便性および吸込口体２６の組立性を向上させる。 Furthermore, the rotary cleaning body unit 33A according to the present embodiment is configured with the turbine 41, the turbine shaft 42, the planetary gear mechanism 43, and the rotary cleaning body 44 as a single module so that the handling convenience and the suction port body 26 can be improved. Improve assembly.
　したがって、本実施形態に係る電気掃除機１、吸込口体２６および回転清掃体ユニット３３、３３Ａによれば、タービン４１、４１Ａを原動機とする回転清掃体４４を備え、電気掃除機１の吸込仕事率を低下させることなく、回転清掃体４４を高トルクで駆動できる。 Therefore, according to the vacuum cleaner 1, the suction port body 26, and the rotary cleaning body units 33 and 33A according to the present embodiment, the rotary cleaner 44 having the turbines 41 and 41A as a prime mover is provided, and the suction work of the vacuum cleaner 1 is performed. The rotary cleaning body 44 can be driven with high torque without reducing the rate.
