Description

本発明は、スティック型電気掃除機等と称される縦型電気掃除機に関するものである。   The present invention relates to a vertical vacuum cleaner called a stick type vacuum cleaner or the like.

従来、この種の縦型電気掃除機は、上部にハンドルを設けると共に電動送風機を内蔵した吸引機構部に対し、塵埃分離手段を着脱自在に取り付けて構成された掃除機本体と、ノズルとを有し、前記電動送風機によって発生させられる吸引気流を前記ノズルから導いて、吸引気流に含まれる塵埃を前記塵埃分離手段で分離した後、溜めるものであった（例えば、特許文献１、２参照）。   Conventionally, this type of vertical vacuum cleaner has a vacuum cleaner body configured by detachably attaching dust separating means to a suction mechanism portion having an electric blower provided with a handle at the top, and a nozzle. However, the suction air flow generated by the electric blower is guided from the nozzle, and dust contained in the suction air flow is separated by the dust separation means and then collected (see, for example, Patent Documents 1 and 2).

そして、従来の前記ノズルは、吸引口を下面に有するノズル本体の上面に、前記掃除機本体下部の接続口に接続される接続管を起伏自在に設けたものであり、前記ノズルを床面に当てた状態で、前記接続管に接続された前記掃除機本体を自在に傾けることができるようになっていた。そして、前記掃除機本体及びこれに接続された接続管は、床面を掃除する場合、通常、比較的起こされた状態で使用されると共に、ベッドや椅子等の下の床面を掃除する場合、比較的寝かされた状態で使用される。   The conventional nozzle is provided with a connecting pipe connected to the connection port at the lower part of the cleaner body on the upper surface of the nozzle body having a suction port on the lower surface, and the nozzle on the floor surface. The vacuum cleaner main body connected to the connection pipe can be freely tilted in the applied state. The vacuum cleaner body and the connecting pipe connected thereto are usually used in a relatively raised state when cleaning the floor surface, and when the floor surface under a bed or chair is cleaned. Used in a relatively laid state.

Further, the short pipe portion 18 of the connection pipe 14 communicates with the opening 16. In addition, an outer tube 21 that is externally fitted to the receiving connection port 6 to be connected is provided on the outer periphery of the connection tube portion 17. Wheels 23 that roll on the floor surface 22 are provided on both the left and right sides of the rear lower portion of the nozzle body 13. Further, a brush portion 24 is provided slightly behind the suction port 19.

そして、前記開口部１６に、前記接続管部１７の短管部１８が揺動可能に連結されている。この連結について説明する。なお、この説明では、図４の姿勢に基づいて、前後及び上下を規定する。前記開口部１６の前端縁には、凹状の第一の円弧面２５が形成されている。また、前記開口部１６の底面から後端縁にかけて、前記第一の円弧面２５と対向するように、凹状の第二の円弧面２６が形成されている。なお、前記第一の円弧面２５の曲率半径より、前記第二の円弧面２６の曲率半径は大きく形成されている。そして、前記短管部１８の下部前側には、前記第一の円弧面２５に対して摺動可能に当接する第三の円弧面２７が形成される。また、前記短管部１８の後側には、間接的に前記第二の円弧面２６側と摺動可能に当接する第四の円弧面２８が形成される。なお、本実施例では、前記第二の円弧面２６と第四の円弧面２８との間に、円弧面部材２９が摺動自在に介在している。前記第四の円弧面２８の下端縁部には、後方、即ち前記貫通経路２０と反対側に向けて掛部３０が設けられると共に、前記第四の円弧面２８と隣接する前記円弧面部材２９の上端縁部には、前方、即ち前記貫通経路２０側に向けて受部３１が設けられる。そして、この受部３１は、前記掛部３０に掛かるように構成される。即ち、図４に示すように、前記接続管１４を立てた状態では、前記第四の円弧面２８の下端と、前記開口部１６の後端との間に開口が生じるが、前記受部３１が前記掛部３０に掛かることによって、前記円弧面部材２９が前記接続管１４に吊り下げられるので、前記第四の円弧面２８の下端と前記開口部１６の後端との間の開口が前記円弧面部材２９によって塞がれる。一方、図５に示すように、前記接続管１４を後方に最大限倒した状態では、前記掛部３０と受部３１とが離れ、前記第四の円弧面２８と、円弧面部材２９と、前記第二の円弧面２６とが重なった状態となる。即ち、この状態では、前記円弧面部材２９は、前記開口部１６から前記ノズル本体１３内に収容される。なお、前記接続管１４及び円弧面部材２９は、前記ノズル本体１３に対し、前記第一の円弧面２５及び第三の円弧面２７の中心を回動中心３２として揺動可能となるように設けられる。   And the short pipe part 18 of the said connecting pipe part 17 is connected with the said opening part 16 so that rocking | fluctuation is possible. This connection will be described. In this description, front and rear and top and bottom are defined based on the posture of FIG. A concave first arcuate surface 25 is formed at the front edge of the opening 16. A concave second arc surface 26 is formed from the bottom surface of the opening 16 to the rear edge so as to face the first arc surface 25. The radius of curvature of the second arc surface 26 is formed larger than the radius of curvature of the first arc surface 25. A third arcuate surface 27 that is slidably in contact with the first arcuate surface 25 is formed on the lower front side of the short pipe portion 18. In addition, a fourth arc surface 28 is formed on the rear side of the short pipe portion 18 so as to indirectly contact the second arc surface 26 side in a slidable manner. In this embodiment, an arc surface member 29 is slidably interposed between the second arc surface 26 and the fourth arc surface 28. A hooking portion 30 is provided at the lower end edge of the fourth arcuate surface 28 toward the rear side, that is, on the side opposite to the through path 20, and the arcuate surface member 29 adjacent to the fourth arcuate surface 28. A receiving part 31 is provided at the upper edge of the front side, that is, toward the through path 20. The receiving portion 31 is configured to be hung on the hanging portion 30. That is, as shown in FIG. 4, in the state where the connection pipe 14 is erected, an opening is generated between the lower end of the fourth arc surface 28 and the rear end of the opening 16, but the receiving portion 31. Since the arc surface member 29 is suspended from the connecting pipe 14 by hanging on the hanging portion 30, the opening between the lower end of the fourth arc surface 28 and the rear end of the opening portion 16 is The circular arc member 29 is closed. On the other hand, as shown in FIG. 5, in the state where the connection pipe 14 is tilted back to the maximum extent, the hook portion 30 and the receiving portion 31 are separated, and the fourth arc surface 28, the arc surface member 29, The second arc surface 26 is overlapped. That is, in this state, the arcuate surface member 29 is accommodated in the nozzle body 13 through the opening 16. The connecting pipe 14 and the arcuate surface member 29 are provided so as to be swingable with respect to the nozzle body 13 with the centers of the first arcuate surface 25 and the third arcuate surface 27 as the rotation center 32. It is done.

そして、前記接続管１４、ひいてはこれに接続された前記掃除機本体２が後方に最大限倒された状態にあって、前記床面２２から前記接続管１４の回動中心３２までの第一の高さＡは、前記塵埃分離手段８を備えている前記掃除機本体２の上下方向の第二の高さＢのほぼ半分、具体的には、第一の高さＡは第二の高さＢの１／３〜２／３の範囲に設定されている。なお、第一の高さＡが第二の高さＢの１／３より小さい場合、前記凸部１５の高さ、即ち、この凸部１５に設けられる前記回動中心３２の第一の高さＡが低すぎるか、前記接続管１４の設計上の最大傾斜角度が小さすぎるか、或いは前記掃除機本体２が大きすぎるということなので、適正に設計すべきである。一方、第一の高さＡが第二の高さＢの２／３より大きい場合、現実的には、前記凸部１５の高さ、即ち第一の高さＡが高すぎるということなので、適正に設計すべきである。なお、前記中心軸線７から前記掃除機本体２の後端までの距離（本実施例では、前記中心軸線７から後述するフック４４又は４４Ａの後端までの距離、そのような突起物がない場合は、前記吸引機構部４又はサイクロン筒８の半径）が、前記第一の高さＡと等しいか、又はそれよりも小さければ理想的である。このような構造であれば、前記中心軸線７が水平となるまで前記掃除機本体２を後方に倒すことが可能である。但し、現実的には、前記フック４４又は４４Ａが床面２２に接して床面２２を傷めないように、前記掃除機本体２を最大限後方に倒した状態において、前記中心軸線７が水平よりもやや後上がりとなるように設計される。   The connecting pipe 14 and the vacuum cleaner main body 2 connected to the connecting pipe 14 are in a state where they are tilted back to the maximum, and the first from the floor surface 22 to the rotation center 32 of the connecting pipe 14. The height A is substantially half of the second height B in the vertical direction of the cleaner body 2 provided with the dust separating means 8, and specifically, the first height A is the second height. The range is set to 1/3 to 2/3 of B. When the first height A is smaller than 1/3 of the second height B, the height of the convex portion 15, that is, the first height of the rotation center 32 provided on the convex portion 15. Since the height A is too low, the design maximum inclination angle of the connecting pipe 14 is too small, or the main body 2 of the cleaner is too large, it should be designed appropriately. On the other hand, when the first height A is larger than 2/3 of the second height B, the height of the convex portion 15, that is, the first height A is actually too high. It should be designed properly. Note that the distance from the central axis 7 to the rear end of the cleaner body 2 (in this embodiment, the distance from the central axis 7 to the rear end of a hook 44 or 44A, which will be described later, when there is no such projection. Is ideal if the radius of the suction mechanism section 4 or the cyclone cylinder 8) is equal to or smaller than the first height A. With such a structure, the cleaner body 2 can be tilted backward until the central axis 7 becomes horizontal. However, in reality, the central axis 7 is not horizontal when the cleaner body 2 is tilted back to the maximum so that the hook 44 or 44A does not touch the floor 22 and damage the floor 22. It is designed to be slightly uphill.

前記塵埃分離手段８は、図６，７に示すように、前記サイクロン筒９と、このサイクロン筒９内に着脱自在に設けられる渦流発生部材３４とを有して構成される。前記サイクロン筒９は、前記受け接続口６と、この受け接続口６の中心軸線７と同軸状であって前記受け接続口６の上部に連通する導入管部３３と、径大な集塵室３５とを有して一体的に形成される。そして、前記渦流発生部材３４は、その下端が前記導入管部３３の上部に接続されると共に、その上端が前記サイクロン筒９の上端開口に位置するように構成される。なお、前記渦流発生部材３４の上端部は、前記吸引機構部４の電動送風機５に対向して設けられる。前記集塵室３５は、サイクロン筒９の下部に連通している中空形状である。この集塵室３５は、前記導入管部３３の外側を中心軸線７と同軸状に囲んだ形状であって、底面３５Ａと、この底面３５Ａの外周から軸方向に延びて形成された周面３５Ｂとを備えている。これによって、前記掃除機本体２に設けられた前記電動送風機５によって発生させられる吸引気流は、前記ノズル３の吸引口１９から前記接続管１４を介してサイクロン筒９に導かれ、前記サイクロン筒９において前記渦流発生部材３４によって旋回流とされ、遠心力によって塵埃が除かれた後、前記電動送風機を通過して前記掃除機本体２の外部に放出される。この際、前記サイクロン筒９内の旋回流は、このサイクロン筒９の内壁に沿って旋回しながら前記集塵室３５に向かって下降し、この集塵室３５内に分離された塵埃を溜めた後、上昇する。   As shown in FIGS. 6 and 7, the dust separating means 8 includes the cyclone cylinder 9 and a vortex generating member 34 that is detachably provided in the cyclone cylinder 9. The cyclone cylinder 9 includes the receiving connection port 6, an introduction pipe portion 33 that is coaxial with the central axis 7 of the receiving connection port 6 and communicates with the upper portion of the receiving connection port 6, and a large dust collection chamber. 35 and are integrally formed. The eddy current generating member 34 is configured such that a lower end thereof is connected to an upper portion of the introduction pipe portion 33 and an upper end thereof is positioned at an upper end opening of the cyclone cylinder 9. The upper end portion of the eddy current generating member 34 is provided to face the electric blower 5 of the suction mechanism portion 4. The dust collection chamber 35 has a hollow shape communicating with the lower part of the cyclone cylinder 9. The dust collecting chamber 35 has a shape that surrounds the outside of the introduction pipe portion 33 coaxially with the central axis 7, and has a bottom surface 35 </ b> A and a peripheral surface 35 </ b> B that extends from the outer periphery of the bottom surface 35 </ b> A in the axial direction. And. As a result, the suction airflow generated by the electric blower 5 provided in the cleaner body 2 is guided from the suction port 19 of the nozzle 3 to the cyclone cylinder 9 through the connection pipe 14, and the cyclone cylinder 9 , The swirl flow is generated by the eddy current generating member 34, dust is removed by centrifugal force, and then passes through the electric blower and is discharged to the outside of the cleaner body 2.

次に、本実施形態の作用について説明する。まず、前記床面２２を掃除する場合、使用者は前記第二のハンドル１２を把持し、前記ノズル３に対して前記掃除機本体２を適度に傾けた状態で前記電動送風機５を作動させることで、塵埃を含んだ吸引気流を前記ノズル３の吸引口１９から吸引する。この際、前記ノズル３のノズル本体１３に前記凸部１５を設けることで、前記接続管１４の回動中心３２を比較的高くし、前記接続管１４と掃除機本体２とを中心軸線７を基準として同軸状としたことで、第一の高さＡを第二の高さＢのほぼ半分、実施例では第二の高さＢの１／３〜２／３に設定することが可能となり、これによって、前記塵埃分離手段８を備えた前記掃除機本体２を前記床面２２に可及的に近づけることができ、この結果、前記掃除機本体２を水平或いはそれに近い状態まで倒すことができる。このように、前記掃除機本体２を水平或いはそれに近い状態まで倒すことで、ベッドや椅子等の下の床面２２を清掃する際に、前記ノズル３を奥まで挿入することができる。   Next, the operation of this embodiment will be described. First, when cleaning the floor surface 22, the user holds the second handle 12 and operates the electric blower 5 with the vacuum cleaner body 2 tilted moderately with respect to the nozzle 3. Then, the suction airflow containing dust is sucked from the suction port 19 of the nozzle 3. At this time, by providing the convex portion 15 on the nozzle body 13 of the nozzle 3, the rotation center 32 of the connection pipe 14 is made relatively high, and the connection pipe 14 and the cleaner body 2 are connected to the central axis 7. By using a coaxial shape as a reference, it is possible to set the first height A to almost half of the second height B, and in the embodiment, 1/3 to 2/3 of the second height B. Thus, the cleaner body 2 provided with the dust separating means 8 can be brought as close as possible to the floor surface 22, and as a result, the cleaner body 2 can be brought down to a level or close to it. it can. Thus, the nozzle 3 can be inserted deeply when the floor surface 22 under the bed, chair, etc. is cleaned by tilting the vacuum cleaner body 2 horizontally or close to it.

そして、前記電動送風機５を作動させることで、前記吸引口１９から吸引された吸引気流は、前記貫通経路２０及び接続管１４を通過して、前記塵埃分離手段８の渦流発生部材３４から前記サイクロン筒９内に流入する。そして、このサイクロン筒９内に流入した吸引気流は、このサイクロン筒９の内周壁に沿って回転しながら下降する渦流とされる。そして、このように前記サイクロン筒９内で渦流を作り出すことで、この渦流（吸引気流）に含まれる塵埃が遠心力によって前記サイクロン筒９の内周壁に押し付けられ、これによって、塵埃が渦流（吸引気流）から分離されて、前記集塵室３５内に溜められることになる。そして、遠心力によって塵埃が分離されて清浄になった吸引気流は、前記サイクロン筒９の中央側で上昇し、フィルタ（図示せず）、さらには前記電動送風機５を通過して大気に排気される。   Then, by operating the electric blower 5, the suction airflow sucked from the suction port 19 passes through the through path 20 and the connection pipe 14, and from the vortex generating member 34 of the dust separating means 8 to the cyclone. It flows into the cylinder 9. The suction airflow that flows into the cyclone cylinder 9 is a vortex that descends while rotating along the inner peripheral wall of the cyclone cylinder 9. Then, by creating a vortex in the cyclone cylinder 9 in this way, the dust contained in the vortex (suction airflow) is pressed against the inner peripheral wall of the cyclone cylinder 9 by centrifugal force, whereby the dust is swirled (suction) Is separated from the air flow) and stored in the dust collecting chamber 35. Then, the suction airflow, which is cleaned by separating dust by centrifugal force, rises at the center side of the cyclone cylinder 9, passes through a filter (not shown), and further passes through the electric blower 5 and is exhausted to the atmosphere. The

そして、掃除後において、前記集塵室３５内の塵埃を廃棄する場合、前記掃除機本体２を傾けて、前記廃棄用穴３７を下に向けた状態で、指で前記操作部４０Ａを前記集塵室３５側に押圧する。これによって、前記ロック部材４０が、前記回動支持部４０Ｂを回動中心として揺動し、前記係止部４０Ｄが前記ロック受け部４１から離れることで、前記ロック部材４０とロック受け部４１との係止状態が解除される。これによって、前記ヒンジ軸３８を中心として、前記開閉蓋３６が重力によって前記廃棄用穴３７より離れ、この廃棄用穴３７を開放する。このように、前記集塵室３５の側部に設けられた前記廃棄用穴３７を開放することで、前記塵埃分離手段８を前記吸引機構部４から取り外すことなく、また、前記ノズル３を前記塵埃分離手段８から取り外すことなく、前記集塵室３５から塵埃を廃棄することができる。なお、前記掃除機本体２を傾斜させた状態では、前記操作部４０Ａは、前記サイクロン筒９の集塵室３５の底面３５Ａにおける上側となるので、前記操作部４０Ａを操作しても、この操作部４０Ａを操作する手は、前記集塵室３５内の塵埃によって汚れることがない。   After the cleaning, when the dust in the dust collecting chamber 35 is to be discarded, the vacuum cleaner main body 2 is tilted and the operation portion 40A is held by the finger with the disposal hole 37 facing downward. Press toward the dust chamber 35 side. As a result, the lock member 40 swings around the rotation support portion 40B, and the locking portion 40D is separated from the lock receiving portion 41, whereby the lock member 40, the lock receiving portion 41, The locked state of is released. Accordingly, the opening / closing lid 36 is separated from the disposal hole 37 by gravity with the hinge shaft 38 as a center, and the disposal hole 37 is opened. In this way, by opening the disposal hole 37 provided in the side portion of the dust collection chamber 35, the nozzle 3 can be moved without removing the dust separating means 8 from the suction mechanism section 4. The dust can be discarded from the dust collecting chamber 35 without being removed from the dust separating means 8. In the state where the cleaner body 2 is inclined, the operation unit 40A is on the upper side of the bottom surface 35A of the dust collection chamber 35 of the cyclone cylinder 9, so that even if the operation unit 40A is operated, this operation is performed.
