Description

本発明は、操作ハンドル部の操作により床用吸込部および掃除機本体を移動させて清掃作業を行う電気掃除機に関するものである。   The present invention relates to an electric vacuum cleaner that performs a cleaning operation by moving a floor suction portion and a vacuum cleaner body by operating an operation handle portion.

従来、この種の電気掃除機は、下方に開口部を有する床用吸込部の略上方に、集塵室、電動送風機を内蔵した掃除機本体を配してあり、さらに使用者は掃除機本体の略上方に棒または筒状の接続部を突出させ、この接続部の上端に設けた操作ハンドル部を掴んで清掃作業を行っている（例えば、特許文献１参照）。
特開平５−２０２１１号公報 Conventionally, in this type of vacuum cleaner, a vacuum cleaner body including a dust collection chamber and an electric blower is disposed substantially above a floor suction portion having an opening below, and a user can also use a vacuum cleaner body. A rod-like or cylindrical connection portion is projected substantially above, and an operation handle provided at the upper end of the connection portion is grasped to perform cleaning work (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 5-20211

しかしながら、前記従来の構成では、机やベッドなどの高さ方向に制限がある障害物が存在すると、その障害物の下や奥を清掃するときに掃除機本体などが接触するため、使用者は掃除機本体などを床面に近付ける必要があり、この動作を行うために使用者は屈むことになるため、清掃作業が困難であるという課題を有していた。   However, in the conventional configuration, when there is an obstacle with a restriction in the height direction such as a desk or a bed, the cleaner main body or the like contacts when cleaning the bottom or the back of the obstacle. Since it is necessary to bring the main body of the vacuum cleaner close to the floor surface and the user bends to perform this operation, there is a problem that the cleaning work is difficult.

本発明は、前記従来の課題を解決するもので、清掃床面上に存在する障害物の下や奥を容易に清掃することができる電気掃除機を提供することを目的とする。   This invention solves the said conventional subject, and it aims at providing the vacuum cleaner which can easily clean the bottom and the back of the obstruction which exists on a cleaning floor surface.

前記従来の課題を解決するために、本発明の電気掃除機は、掃除機本体と、掃除機本体に内蔵され吸引力を発生させる電動送風機と、掃除機本体と接続された床用吸込部と、床用吸込部と電動送風機との吸気流路の途中に設けられた集塵室と、掃除機本体を前進移動させる走行部と、掃除機本体とは別に設けた操作ハンドル部と、掃除機本体と操作ハンドル部間を接続した可撓性接続部とを備えたものである。   In order to solve the conventional problems, a vacuum cleaner of the present invention includes a vacuum cleaner body, an electric blower built in the vacuum cleaner body and generating suction force, and a floor suction unit connected to the vacuum cleaner body. , A dust collection chamber provided in the middle of the intake passage between the floor suction section and the electric blower, a traveling section for moving the cleaner body forward, an operation handle section provided separately from the cleaner body, and a vacuum cleaner A flexible connecting portion connecting the main body and the operation handle portion is provided.

これによって、掃除機本体が走行部の動作で自動的に前進し障害物の下に入り込み、さらに掃除機本体と操作ハンドル部を接続する可撓性接続部が障害物の縁に接触しても可撓性接続部が曲がり、可撓性接続部が障害物の下や奥へ円滑に入り込む。つまり操作ハンドル部を床面近くまで下げることなく使い勝手が向上し、掃除機本体が障害物の下や奥へ入り込み、塵埃などを集塵するものである。   As a result, the main body of the cleaner automatically moves forward by the operation of the traveling part and enters under the obstacle, and even if the flexible connection part connecting the main body of the cleaner and the operation handle part contacts the edge of the obstacle. The flexible connection portion bends and the flexible connection portion smoothly enters under and behind the obstacle. That is, the user-friendliness is improved without lowering the operation handle portion to near the floor surface, and the cleaner body enters under or behind the obstacle to collect dust.

本発明の電気掃除機は、使い勝手を向上でき、かつ障害物の下や奥まで確実に清掃を行うことができる。   The electric vacuum cleaner of the present invention can improve usability and can be reliably cleaned to the bottom and back of the obstacle.

第１の発明は、掃除機本体と、掃除機本体に内蔵され吸引力を発生させる電動送風機と、掃除機本体と接続された床用吸込部と、床用吸込部と電動送風機との吸気流路の途中に設けられた集塵室と、掃除機本体を前進移動させる走行部と、掃除機本体とは別に設けた操作ハンドル部と、掃除機本体と操作ハンドル部間を接続した可撓性接続部とを備えた電気掃除機とすることにより、掃除機本体が走行部の動作で自動的に前進し障害物の下に入り込み、さらに掃除機本体と操作ハンドル部を接続する可撓性接続部が障害物の縁に接触しても可撓性接続部が曲がり、可撓性接続部が障害物の下や奥へ円滑に入り込む。つまり操作ハンドル部を床面近くまで下げることなく掃除機本体が障害物の下や奥へ入り込み、塵埃などを集塵するものである。この結果、使い勝手を向上でき、かつ障害物の下や奥まで確実に清掃を行うことができる。   1st invention is a vacuum cleaner main body, the electric blower which is built in a vacuum cleaner main body and generate | occur | produces suction force, the suction part for floors connected with the vacuum cleaner main body, the suction flow for floor suction parts, and an electric blower A dust collection chamber provided in the middle of the road, a traveling part for moving the cleaner body forward, an operation handle part provided separately from the cleaner body, and a flexibility connecting the cleaner body and the operation handle part By making the vacuum cleaner equipped with a connection part, the vacuum cleaner body automatically moves forward by the operation of the traveling part and enters under the obstacle, and further, the flexible connection that connects the cleaner body and the operation handle part Even if the portion comes into contact with the edge of the obstacle, the flexible connection portion bends, and the flexible connection portion smoothly enters under or behind the obstacle. That is, the vacuum cleaner main body enters under or behind the obstacle without collecting the operation handle part close to the floor, and collects dust and the like. As a result, usability can be improved, and cleaning can be reliably performed to the bottom and back of the obstacle.

第２の発明は、特に、第１の発明において、走行部は、掃除機本体の前進移動時に操作ハンドル部により掃除機本体を後方に引くことで前進力が低下または停止するように構成したことにより、操作ハンドル部を引くときの掃除機本体と床面との抵抗が減り、特に絨毯などの滑りにくい床面上に掃除機本体があるときに使用者は少ない力でスムースに掃除機本体を引き戻すことができる。これにより掃除機本体が絨毯などの床面に引っ掛かって転倒することを防ぐこともできる。   According to a second aspect of the invention, in particular, in the first aspect of the invention, the traveling unit is configured such that the forward force is reduced or stopped by pulling the cleaner body backward by the operation handle when the cleaner body moves forward. This reduces the resistance between the vacuum cleaner body and the floor surface when pulling the operation handle, especially when the vacuum cleaner body is on a slippery floor such as a carpet, and the user can smoothly move the vacuum cleaner body with less force. Can be pulled back. Thereby, it can also prevent that a vacuum cleaner main body is caught on floor surfaces, such as a carpet, and falls.

第３の発明は、特に、第１または第２の発明において、操作ハンドル部に設けた針路制御スイッチと、この針路制御スイッチの操作と連動して走行部による掃除機本体の走行針路を変更する針路変更部とを有することにより、使用者は任意に掃除機本体の走行針路を変更でき、かつ使用者が掃除機本体に対して外部から力を加えて針路を変更していることではないため、既に清掃済みの床面を避けて掃除機本体を移動させることができ、また障害物を避けることができることで効率よく清掃作業を行うことができる。   According to a third aspect of the invention, in particular, in the first or second aspect of the invention, the course control switch provided in the operation handle portion and the running course of the cleaner body by the running section are changed in conjunction with the operation of the course control switch. By having the course changing section, the user can arbitrarily change the traveling course of the cleaner body, and the user is not changing the course by applying force to the cleaner body from the outside. The main body of the cleaner can be moved while avoiding the already cleaned floor surface, and obstacles can be avoided, so that the cleaning work can be performed efficiently.

第４の発明は、特に、第１〜第３のいずれか１つの発明において、可撓性接続部は、掃除機本体と操作ハンドル部の少なくとも一方に設けた収容部に収容可能としたことにより、清掃作業を一時中断するとき、掃除機本体を持ち運んで移動するとき、清掃終了後に収納するときに可撓性接続部が使用者や障害物に接触することなく、使い勝手を向上することができる。さらに収納スペースを小さくすることができる。   According to a fourth aspect of the invention, in particular, in any one of the first to third aspects of the invention, the flexible connection portion can be accommodated in an accommodation portion provided in at least one of the cleaner body and the operation handle portion. When the cleaning operation is temporarily suspended, when the cleaner body is carried and moved, the flexible connecting portion does not come into contact with the user or an obstacle when stored after the cleaning is completed, and the usability can be improved. . Furthermore, the storage space can be reduced.

第５の発明は、特に、第１〜第４のいずれか１つの発明において、可撓性接続部は、可撓性の状態から剛体、剛体から可撓性の状態へと変化可能な構成としたことにより、可撓性接続部の可撓性状態における効果に加え、可撓性接続部を剛体へと変化させることで、掃除機本体の走行が困難な床面において、使用者が直接掃除機本体に力を加えて操作できるので、掃除機本体が意図せぬ方向に進んだり、転倒したりすることを防ぎ円滑に清掃作業を行うことができる。さらに操作ハンドル部を握って掃除機本体を持ち上げることができるので、棚や壁などの床面より高い場所の清掃箇所を清掃できる。加えて使用者が操作ハンドル部から接続部を介して掃除機本体および床用吸込具を清掃面に押し付けることができるので、集塵性能を向上することができる。   According to a fifth aspect of the invention, in particular, in any one of the first to fourth aspects of the invention, the flexible connecting portion can change from a flexible state to a rigid body, and from a rigid body to a flexible state. As a result, in addition to the effect of the flexible connection portion in the flexible state, the user can directly clean the floor surface where it is difficult for the cleaner body to travel by changing the flexible connection portion to a rigid body. Since the operation can be performed by applying force to the machine main body, it is possible to prevent the cleaner main body from proceeding in an unintended direction and to prevent the machine from being overturned and to perform the cleaning operation smoothly. Furthermore, since the vacuum cleaner body can be lifted by holding the operation handle, it is possible to clean a cleaning portion at a place higher than the floor such as a shelf or a wall. In addition, since the user can press the vacuum cleaner main body and the floor suction tool from the operation handle portion via the connection portion, the dust collection performance can be improved.

第６の発明は、特に、第１〜第５のいずれか１つの発明において、可撓性接続部は、掃除機本体と操作ハンドル部の少なくとも一方に設けた嵌合部で分離可能としたことにより、使用者や障害物に可撓性接続部が絡み付いた場合に、使用者や障害物から素早く可撓性接続部を取り除くことができ、速やかに清掃作業を続行できる。また掃除機本体と操作ハンドル部を別々に収納することができるため、２箇所の小さな収納庫に分けて収納できる。   In a sixth aspect of the invention, in particular, in any one of the first to fifth aspects of the invention, the flexible connecting portion can be separated by a fitting portion provided on at least one of the cleaner body and the operation handle portion. Thus, when the flexible connection portion is entangled with the user or the obstacle, the flexible connection portion can be quickly removed from the user or the obstacle, and the cleaning operation can be continued promptly. Moreover, since the vacuum cleaner main body and the operation handle portion can be stored separately, they can be stored separately in two small storages.

第７の発明は、特に、第１〜第６のいずれか１つの発明において、操作ハンドル部と掃除機本体とは、その両者を結合する結合部を有したことにより、操作ハンドル部を掃除機本体に結合させることが可能であり、操作ハンドル部と掃除機本体とを結合することで、操作ハンドル部を持ちながら掃除機本体を持ち上げて移動させることができ、さらに操作ハンドル部と掃除機本体との距離が近接することにより、手元付近の掃除を行うことができるようになる。   In a seventh aspect of the invention, in particular, in any one of the first to sixth aspects of the invention, the operation handle portion and the cleaner body have a coupling portion that couples both, so that the operation handle portion is cleaned. It can be combined with the main body, and by connecting the operation handle part and the cleaner body, the cleaner body can be lifted and moved while holding the operation handle part, and the operation handle part and the cleaner body When the distance between the two is close, the vicinity of the hand can be cleaned.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１、図２は、本発明の実施の形態１における電気掃除機を示している。 (Embodiment 1)
1 and 2 show a vacuum cleaner according to Embodiment 1 of the present invention.

図１に示すように、本実施の形態における電気掃除機は、掃除機本体２１と、掃除機本体２１に内蔵され吸引力を発生させる電動送風機２２と、掃除機本体２１の前方下部に一体化または別体で接続された床用吸込部２３と、床用吸込部２３の下方に設けた吸引を行う開口部２４と電動送風機２２との吸気流路の途中に設けられた集塵室３５と、掃除機本体２１を前進移動させる回転ブラシ２５からなる走行部と、掃除機本体２１とは別に設けた操作ハンドル部３０と、掃除機本体２１と操作ハンドル部３０間を接続したワイヤー状の可撓性接続部３２とを備えている。   As shown in FIG. 1, the electric vacuum cleaner in the present embodiment is integrated with a vacuum cleaner main body 21, an electric blower 22 that is built in the vacuum cleaner main body 21 and generates a suction force, and a front lower portion of the vacuum cleaner main body 21. Alternatively, the floor suction portion 23 connected separately, the opening 24 provided below the floor suction portion 23 and the dust collecting chamber 35 provided in the middle of the intake air flow path of the electric blower 22; , A traveling part composed of a rotating brush 25 for moving the cleaner body 21 forward, an operation handle part 30 provided separately from the cleaner body 21, and a wire-like connection connecting the cleaner body 21 and the operation handle part 30. And a flexible connecting portion 32.

床用吸込部２３の開口部２４内には、前転方向に回転し床面３６の塵埃を掻き揚げたり、床面３６を磨いたりすることができる回転ブラシ２５を内蔵しており、この回転ブラシ２５はベルト（図示せず）を介して回転ブラシ駆動用モータ（図示せず）に接続されている。   In the opening 24 of the floor suction portion 23, there is a built-in rotating brush 25 that rotates in the forward rotation direction to sweep up dust on the floor surface 36 and polish the floor surface 36. The brush 25 is connected to a rotating brush driving motor (not shown) via a belt (not shown).

同じく掃除機本体２１の前方下部の回転ブラシ２５近傍には、回動する先端が略湾曲形状（曲面）の突部２６を有しており、突部２６の先端は回動中心２７から後方かつ下方に配してあり、突部２６が前方に回り込まないようにストッパー部２８を設けている。なお、掃除機本体２１の後方下部には、前後方向に回転自在な走行ローラー２９を配している。   Similarly, in the vicinity of the rotary brush 25 near the front lower part of the vacuum cleaner main body 21, a rotating tip has a substantially curved (curved) protrusion 26, and the tip of the protrusion 26 is rearward from the rotation center 27. A stopper portion 28 is provided so as to prevent the protrusion 26 from going forward. A traveling roller 29 that is rotatable in the front-rear direction is disposed in the lower rear portion of the cleaner body 21.

掃除機本体２１と別に設けた操作ハンドル部３０には、電動送風機２２や回転ブラシ２５の運転を操作する操作スイッチ３１を配してある。また、掃除機本体２１後方と操作ハンドル部３０との間を接続した可撓性接続部３２は、その内部に操作スイッチ３１と掃除機本体２１内の制御回路３３との信号をやり取りするための金属製の信号線（図示せず）を配している。   An operation handle 31 provided separately from the cleaner body 21 is provided with an operation switch 31 for operating the electric blower 22 and the rotating brush 25. Moreover, the flexible connection part 32 which connected between the cleaner body 21 back and the operation handle part 30 is used for exchanging signals between the operation switch 31 and the control circuit 33 in the cleaner body 21 therein. A metal signal line (not shown) is provided.

また、掃除機本体２１には、電動送風機２２や回転ブラシ駆動用モータ、スイッチの制御などに使用される電源としての充電池３４を内蔵している。   Further, the cleaner body 21 incorporates a rechargeable battery 34 as a power source used for controlling an electric blower 22, a motor for driving a rotating brush, a switch, and the like.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

清掃作業を行うために、使用者は操作ハンドル部３０を手に持ち、図１（ａ）のように、掃除機本体２１を清掃面である使用者前方の床面３６に置く。そして操作スイッチ３１を操作すると信号が可撓性接続部３２内部の信号線を通って掃除機本体２１内の制御回路３３へ送られ、制御回路３３からの指令で電動送風機２２が動作を開始して吸引力が発生し、床用吸込部２３の開口部２４から床面３６の塵埃を吸込むことになる。   In order to perform the cleaning operation, the user holds the operation handle portion 30 in his / her hand, and places the cleaner body 21 on the floor surface 36 in front of the user, which is a cleaning surface, as shown in FIG. When the operation switch 31 is operated, a signal is sent to the control circuit 33 in the cleaner body 21 through the signal line in the flexible connection portion 32, and the electric blower 22 starts to operate in response to a command from the control circuit 33. Thus, a suction force is generated, and dust on the floor surface 36 is sucked from the opening 24 of the floor suction portion 23.

吸込まれた塵埃は集塵室３５で塵埃と空気流に分離され、空気流は電動送風機２２を通過して掃除機本体２１外部へ排出される。   The sucked dust is separated into dust and air flow in the dust collecting chamber 35, and the air flow passes through the electric blower 22 and is discharged to the outside of the cleaner body 21.

電動送風機２２が動作すると同時にベルトを介して回転ブラシ駆動用モータの回転力を回転ブラシ２５へ伝達し、回転ブラシ２５を回転させて床面３６の塵埃を掻き揚げるとともに、床面３６自体を磨くことになる。このとき回転ブラシ２５は勢い良く前転しているので、回転ブラシ２５が走行部である駆動輪の役目を担い掃除機本体２１全体が矢印Ａのように自然と前進することになる。さらに掃除機本体２１後方には走行ローラー２９を配しているため、円滑に掃除機本体２１が前進できる。   At the same time as the electric blower 22 operates, the rotational force of the rotary brush driving motor is transmitted to the rotary brush 25 via the belt, and the rotary brush 25 is rotated to sweep up dust on the floor surface 36 and polish the floor surface 36 itself. It will be. At this time, since the rotary brush 25 is moving forward vigorously, the rotary brush 25 plays a role of a driving wheel as a traveling portion, and the entire cleaner body 21 moves forward as indicated by an arrow A. Furthermore, since the traveling roller 29 is arranged behind the cleaner body 21, the cleaner body 21 can move forward smoothly.

なお、掃除機本体２１前進時には突部２６の先端は、回動中心２７から後方かつ下方にあり突部２６は斜めになりながら床面３６上を滑っている状態である。   When the vacuum cleaner main body 21 moves forward, the tip of the protrusion 26 is rearward and downward from the rotation center 27 and the protrusion 26 is sliding on the floor surface 36 while being inclined.

掃除機本体２１が前進して当初たわんでいた可撓性接続部３２が伸びきると、図１（ｂ）のように、使用者は操作ハンドル部３０を矢印Ｂ方向に引いて掃除機本体２１を矢印Ｃ方向に引き寄せることになる。そのとき突部２６の先端が床面３６と強く当たり突部２６が起きて掃除機本体２１前方が僅かに浮き上がる。突部２６はストッパー部２８を設けているので掃除機本体２１前方に回り込むことなく、掃除機本体２１を引き戻している間中、突部２６が起きた状態になり掃除機本体２１前方を浮き上がらせた状態を維持している。また突部２６の先端が略湾曲形状をしているので、突部２６が起きて先端が床面３６に接している状態でも床面３６との摩擦を低減している。   When the cleaner main body 21 moves forward and the flexible connecting portion 32 that was initially bent is extended, the user pulls the operation handle 30 in the direction of arrow B as shown in FIG. It will be drawn in the direction of arrow C. At that time, the tip of the protrusion 26 strongly hits the floor surface 36 and the protrusion 26 is raised, and the front of the cleaner body 21 is slightly lifted. Since the protrusion 26 is provided with the stopper portion 28, the protrusion 26 is raised while the cleaner body 21 is pulled back without going around the cleaner body 21, and the front of the cleaner body 21 is lifted up. Is maintained. Further, since the tip of the protrusion 26 has a substantially curved shape, the friction with the floor surface 36 is reduced even when the protrusion 26 is raised and the tip is in contact with the floor surface 36.

掃除機本体２１前方が浮き上がると同時に回転ブラシ２５が床面３６に及ぼす回転力が減少して掃除機本体２１が前進しようとする力が弱まり、少ない操作力で掃除機本体２１を引き戻すことができる。もちろん可撓性接続部３２が伸びきる前に操作ハンドル部３０を引いて掃除機本体２１を引き寄せることもできるものである。   At the same time that the front of the cleaner body 21 is lifted, the rotational force exerted by the rotary brush 25 on the floor surface 36 is reduced, and the force that the cleaner body 21 tries to advance is weakened. . Of course, before the flexible connection part 32 is extended, the operation handle part 30 can be pulled to draw the cleaner main body 21 together.

操作ハンドル部３０を引き終わると掃除機本体２１が一瞬停止するが、回転ブラシ２５が前転する回転力があるため、突部２６が倒れて掃除機本体２１前方が床面３６に近接して回転ブラシ２５が床面３６に及ぼす回転力が強くなり再び掃除機本体２１が前進することになる。この一連の動作を繰り返しながら清掃作業を行うものである。   When the operation handle 30 is completely pulled, the cleaner body 21 stops for a moment. However, since the rotary brush 25 has a rotational force, the protrusion 26 falls down and the front of the cleaner body 21 comes close to the floor surface 36. The rotational force exerted on the floor surface 36 by the rotating brush 25 becomes stronger, and the cleaner body 21 moves forward again. The cleaning operation is performed while repeating this series of operations.

図２に示すように、清掃作業中、机やベッドなどの高さ方向に制限がある障害物３７が存在した場合、掃除機本体２１が障害物３７の下に入り込み前進を続ける。このとき操作ハンドル部３０と掃除機本体２１とを接続する接続部が可撓性であるので、障害物３７と接触している箇所で屈曲し、操作ハンドル部３０を若干下げるだけで掃除機本体２１は障害物の奥へと前進していくものである。なお、図２の破線は、従来の電気掃除機を示しており、障害物３７が存在した場合、使用者は掃除機本体および操作ハンドル部を床面に近付ける必要がある。   As shown in FIG. 2, during the cleaning operation, when there is an obstacle 37 that is restricted in the height direction, such as a desk or a bed, the cleaner body 21 enters under the obstacle 37 and continues to advance. At this time, since the connecting portion connecting the operation handle portion 30 and the cleaner main body 21 is flexible, the cleaner main body is bent only at a position where it is in contact with the obstacle 37 and the operation handle portion 30 is slightly lowered. 21 advances to the back of the obstacle. The broken line in FIG. 2 shows a conventional electric vacuum cleaner. When an obstacle 37 exists, the user needs to bring the main body of the vacuum cleaner and the operation handle portion close to the floor surface.

以上のように、本実施の形態においては、掃除機本体２１を前進移動させる走行部である回転ブラシ２５と、掃除機本体２１と別体で操作ハンドル部３０を設け、掃除機本体２１と操作ハンドル部３０との間を可撓性接続部３２で接続したことにより、掃除機本体２１が走行部である回転ブラシ２５の回転力で自動的に前進し障害物の下に入り込み、さらに掃除機本体２１と操作ハンドル部３０を接続する可撓性接続部３２が障害物の縁に接触したとしても可撓性接続部３２が曲がり、可撓性接続部３２が障害物の下や奥へ円滑に入り込む。つまり操作ハンドル部３０を床面３６近くまで下げることなく掃除機本体２１が障害物の下や奥へ入り込み、塵埃などを集塵するものである。この結果、使い勝手を向上でき、かつ障害物の下や奥まで確実に清掃を行うことができる。   As described above, in the present embodiment, the rotary brush 25 which is a traveling unit for moving the cleaner body 21 forward, and the operation handle 30 are provided separately from the cleaner body 21, and the cleaner body 21 is operated. By connecting the handle portion 30 with the flexible connecting portion 32, the cleaner body 21 automatically moves forward by the rotational force of the rotating brush 25, which is the running portion, and enters under the obstacle, and further the cleaner. Even if the flexible connection part 32 connecting the main body 21 and the operation handle part 30 comes into contact with the edge of the obstacle, the flexible connection part 32 bends and the flexible connection part 32 smoothly moves under and behind the obstacle. Get in. That is, the vacuum cleaner main body 21 enters under or behind the obstacle without lowering the operation handle 30 close to the floor 36, and collects dust and the like. As a result, usability can be improved, and cleaning can be reliably performed to the bottom and back of the obstacle.

また、走行部である回転ブラシ２５は、掃除機本体２１前進時に操作ハンドル部３０を用い可撓性接続部３２を介して掃除機本体２１を引いたときに前進する力が低下もしくは停止する構成とすることにより、操作ハンドル部３０を引くときの掃除機本体２１と床面３６との抵抗が減り、特に絨毯などの滑りにくい床面３６上に掃除機本体２１があるときに使用者は少ない力でスムースに掃除機本体２１を引き戻すことができる。これにより掃除機本体２１が絨毯などの床面３６に引っ掛かって転倒することを防ぐこともできる。   In addition, the rotating brush 25 that is a traveling unit is configured such that when the cleaner main body 21 is pulled through the flexible connection portion 32 using the operation handle portion 30 when the cleaner main body 21 moves forward, the forward force is reduced or stopped. By doing so, the resistance between the cleaner body 21 and the floor surface 36 when pulling the operation handle 30 is reduced, and there are few users especially when the cleaner body 21 is on the non-slip floor surface 36 such as a carpet. The vacuum cleaner body 21 can be pulled back smoothly with force. Thereby, it can also prevent that the cleaner main body 21 is caught on the floor surfaces 36, such as a carpet, and falls.

（実施の形態２）
図３は、本発明の実施の形態２における電気掃除機を示している。実施の形態１と同一要素については同一符号を付してその説明を省略する。 (Embodiment 2)
FIG. 3 shows a vacuum cleaner according to Embodiment 2 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態における電気掃除機は、走行部である回転ブラシ２５の両端部近傍にはそれぞれ上下方向に出し入れ可能な棒状の針路変更部４１を有しており、この針路変更部４１はソレノイド式のアクチュエータ４２に連結されている。また操作ハンドル部３０には、このアクチュエータ４２を動作させる針路制御スイッチ４３を設けている。その他の構成は実施の形態１と同様である。   The vacuum cleaner in the present embodiment has rod-shaped course changing sections 41 that can be inserted and removed in the vertical direction near both ends of the rotating brush 25 that is a running section. The course changing section 41 is a solenoid type. The actuator 42 is connected. The operation handle portion 30 is provided with a course control switch 43 for operating the actuator 42. Other configurations are the same as those of the first embodiment.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

掃除機本体２１の針路Ｄ上にある障害物３８を回避するために、例えば掃除機本体２１を左方向Ｅへ針路を変更させたいときには、使用者は針路制御スイッチ４３の内、左へ曲がるスイッチを押す。   In order to avoid the obstacle 38 on the course D of the cleaner body 21, for example, when the course of the cleaner body 21 is to be changed in the left direction E, the user turns the left of the course control switch 43.

針路制御スイッチ４３からの信号を掃除機本体２１側の制御回路３３が受けて、アクチュエータ４２が動作し左端の針路変更部４１が突出して床面３６に接触する。このとき掃除機本体２１左端が浮き上がり、つまり回転ブラシ２５左端の回転力が減るため、相対的に右端の回転力が増すことになり、結果として掃除機本体２１が左に曲がることになる。これは針路制御スイッチ４３を押し続けている間続行される。また同様に右へ曲がるスイッチを押すと掃除機本体２１が右に曲がることになる。   The control circuit 33 on the cleaner body 21 side receives a signal from the course control switch 43, and the actuator 42 operates to project the left end course changing section 41 to contact the floor surface 36. At this time, the left end of the cleaner main body 21 is lifted, that is, the rotational force at the left end of the rotary brush 25 is decreased, so that the rotational force at the right end is relatively increased. As a result, the cleaner main body 21 is turned to the left. This is continued while the course control switch 43 is kept pressed. Similarly, when a switch that turns to the right is pressed, the vacuum cleaner body 21 turns to the right.

以上のように、本実施の形態においては、使用者は任意に掃除機本体２１の走行針路を変更でき、かつ使用者が掃除機本体２１に対して外部から力を加えて針路を変更していることではないため、既に清掃済みの床面３６を避けて掃除機本体２１を移動させることができ、また障害物を避けることができることで効率よく清掃作業を行うことができる。   As described above, in the present embodiment, the user can arbitrarily change the traveling course of the cleaner body 21 and the user can change the course by applying a force to the cleaner body 21 from the outside. Therefore, the cleaner main body 21 can be moved while avoiding the floor surface 36 that has already been cleaned, and an obstacle can be avoided, so that the cleaning operation can be performed efficiently.

FIG. 4 shows a vacuum cleaner according to Embodiment 3 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態における電気掃除機は、掃除機本体２１後端に、可撓性接続部３２を巻き取る第１の巻取り機構部５１を内蔵した掃除機本体２１側の収容部５２を設け、さらに操作ハンドル部３０前端に、可撓性接続部３２を巻き取る第２の巻取り機構部５３を内蔵した操作ハンドル部３０側の収容部５４を設けてあり、第１および第２の巻取り機構部５１、５３は、内蔵する巻取り用小型モータ（図示せず）の駆動により自動的に可撓性接続部３２を巻き取ることができる構成としている。さらに操作ハンドル部３０には、巻取りスイッチ５５と巻取り解除スイッチ５６が追加されている。その他の構成は実施の形態１と同様である。   The vacuum cleaner in the present embodiment is provided with a housing portion 52 on the cleaner body 21 side including a first winding mechanism 51 that winds the flexible connection portion 32 at the rear end of the cleaner body 21. In addition, an accommodation portion 54 on the side of the operation handle portion 30 containing a second winding mechanism portion 53 for winding the flexible connection portion 32 is provided at the front end of the operation handle portion 30, and the first and second winding portions are provided. The mechanism portions 51 and 53 are configured to be able to automatically wind up the flexible connection portion 32 by driving a built-in small winding motor (not shown). Further, a winding switch 55 and a winding release switch 56 are added to the operation handle portion 30. Other configurations are the same as those of the first embodiment.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

清掃作業を一時中断するときに、使用者は操作ハンドル部３０を床面３６に置くが、このとき操作ハンドル部３０の巻取りスイッチ５５を押すことで第１および第２の巻取り機構部５１、５３が可撓性接続部３２を巻取り、つまり可撓性接続部３２が掃除機本体側の収容部５２および操作ハンドル部側の収容部５４へ収容される。結果として、掃除機本体２１と操作ハンドル部３０との間に出ている可撓性接続部３２をたわみなく短くしている。   When temporarily suspending the cleaning operation, the user places the operation handle portion 30 on the floor surface 36. At this time, the first and second take-up mechanism portions 51 are pressed by pressing the take-up switch 55 of the operation handle portion 30. , 53 winds up the flexible connecting portion 32, that is, the flexible connecting portion 32 is accommodated in the accommodating portion 52 on the cleaner body side and the accommodating portion 54 on the operation handle portion side. As a result, the flexible connecting portion 32 that protrudes between the cleaner body 21 and the operation handle portion 30 is shortened without bending.

以上のように、本実施の形態においては、清掃作業を一時中断するとき、掃除機本体２１を持ち運んで移動するとき、清掃終了後に収納するときに可撓性接続部３２が収容され使用者や障害物に接触することなく、使い勝手を向上することができる。さらに収納スペースを小さくすることができる。なお、収容部５２、５４はその両者が必ずしも必要ではなく、その一方だけであっても同様な効果が得られるものである。   As described above, in the present embodiment, when the cleaning operation is temporarily interrupted, when the cleaner body 21 is carried and moved, the flexible connection portion 32 is accommodated when stored after the cleaning is completed. Usability can be improved without touching obstacles. Furthermore, the storage space can be reduced. In addition, the accommodating parts 52 and 54 are not necessarily required, and the same effect can be obtained even if only one of them is included.

FIG. 5 shows a vacuum cleaner according to Embodiment 4 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態における電気掃除機は、可撓性接続部３２の外周には、多数の円筒状の剛体部６１を略連続的に配してあり、掃除機本体２１後端には巻取り機構部５１を設けている。さらに操作ハンドル部３０には、巻取りスイッチ５５と巻取り解除スイッチ５６が追加されている。これにより、可撓性接続部３２は、可撓性の状態から剛体、剛体から可撓性の状態へと変化可能な構成としている。その他の構成は実施の形態１と同様である。   In the vacuum cleaner in the present embodiment, a large number of cylindrical rigid body portions 61 are arranged substantially continuously on the outer periphery of the flexible connection portion 32, and a winding mechanism is provided at the rear end of the cleaner body 21. A part 51 is provided. Further, a winding switch 55 and a winding release switch 56 are added to the operation handle portion 30. Thereby, the flexible connection part 32 is set as the structure which can change from a flexible state to a rigid body and a rigid body to a flexible state. Other configurations are the same as those of the first embodiment.

以上のように構成された電気掃除機について、以下その動作、作用を説明する。   About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

可撓性接続部３２は、図５（ａ）のように、通常、可撓性の状態であり、円筒状の剛体部６１は不規則に可撓性接続部３２の周囲に存在しているが、図５（ｂ）のように、掃除機本体２１の走行が困難な起伏の激しい床面３６を清掃する場合には、使用者は可撓性接続部３２の剛体化スイッチである巻取りスイッチ５５を操作し、可撓性接続部３２が掃除機本体２１内に巻き取られ、ある程度巻き取られた段階で多数の円筒状の剛体部６１が強固に略直線状に並ぶことで、可撓性接続部３２が一時的に簡易的な剛体へと変化することになる。その結果、使用者が直接掃除機本体２１に力を加えて操作できるようになるものである。   As shown in FIG. 5A, the flexible connection portion 32 is normally in a flexible state, and the cylindrical rigid body portion 61 is irregularly present around the flexible connection portion 32. However, as shown in FIG. 5B, when cleaning the undulating floor surface 36 where it is difficult for the cleaner body 21 to travel, the user takes up the winding that is a rigid switch of the flexible connection portion 32. The switch 55 is operated so that the flexible connecting part 32 is wound up in the cleaner body 21, and at the stage where the flexible connecting part 32 is wound up to some extent, a large number of cylindrical rigid body parts 61 are firmly arranged in a substantially straight line. The flexible connection part 32 will change into a simple rigid body temporarily. As a result, the user can directly operate the vacuum cleaner body 21 by applying force.

以上のように、本実施の形態においては、可撓性接続部３２の可撓性状態における効果に加え、可撓性接続部３２を剛体へと変化させることで、掃除機本体２１の走行が困難な床面において、使用者が直接掃除機本体２１に力を加えて操作できるので、掃除機本体２１が意図せぬ方向に進んだり、転倒したりすることを防ぎ円滑に清掃作業を行うことができる。さらに操作ハンドル部３０を握って掃除機本体２１を持ち上げることができるので、棚や壁などの床面より高い場所の清掃箇所を清掃できる。加えて使用者が操作ハンドル部３０から接続部を介して掃除機本体２１および床用吸込部２３を清掃面に押し付けることができるので、集塵性能を向上することができる。   As described above, in the present embodiment, in addition to the effect of the flexible connecting portion 32 in the flexible state, the cleaner main body 21 can be run by changing the flexible connecting portion 32 to a rigid body. Since the user can directly operate the cleaner body 21 on a difficult floor surface, the cleaner body 21 can be prevented from proceeding in an unintended direction or falling, and the cleaning work can be performed smoothly. Can do. Furthermore, since the cleaner main body 21 can be lifted by grasping the operation handle part 30, the cleaning part of the place higher than floor surfaces, such as a shelf and a wall, can be cleaned. In addition, since the user can press the cleaner main body 21 and the floor suction portion 23 from the operation handle portion 30 through the connection portion, the dust collection performance can be improved.

FIG. 6 shows a vacuum cleaner according to Embodiment 5 of the present invention. The same elements as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

本実施の形態における電気掃除機は、掃除機本体２１と可撓性接続部３２の接続箇所に分離可能な掃除機本体側の嵌合部７１を設け、さらに操作ハンドル部３０と可撓性接続部３２の接続箇所にも分離可能な操作ハンドル部側の嵌合部７２を有する構成としている。さらに操作ハンドル部３０には、掃除機本体２１側および操作ハンドル部側の嵌合部７１、７２を分離させる分離スイッチ７３が追加されている。その他の構成は実施の形態１と同様である。   The vacuum cleaner in the present embodiment is provided with a separable fitting portion 71 on the vacuum cleaner main body at the connection portion between the vacuum cleaner main body 21 and the flexible connection portion 32, and further, the operation handle portion 30 and the flexible connection. The connection part of the operation handle part side that can be separated also at the connection part of the part 32 is configured to have a fitting part 72. Further, a separation switch 73 for separating the fitting portions 71 and 72 on the cleaner body 21 side and the operation handle portion side is added to the operation handle portion 30. Other configurations are the same as those of the first embodiment.

以上のように、本実施の形態においては、嵌合部７１、７２で分離可能としたことで、使用者や障害物３７に可撓性接続部３２が絡み付いた場合に、操作ハンドル部３０の分離スイッチ７３を操作し掃除機本体２１側または操作ハンドル部の嵌合部７１、７２を分離させることで、使用者や障害物から素早く可撓性接続部３２を取り除くことができ、速やかに清掃作業を続行できる。また掃除機本体２１と操作ハンドル部３０を別々に収納することができるため、２箇所の小さな収納庫に分けて収納できる。なお、嵌合部７１、７２はその両者が必ずしも必要ではなく、その一方だけであっても同様な効果が得られるものである。   As described above, in the present embodiment, the separation by the fitting portions 71 and 72 enables the flexible handle 32 to be entangled with the user or the obstacle 37. By operating the separation switch 73 to separate the fitting portions 71 and 72 of the cleaner main body 21 side or the operation handle portion, the flexible connection portion 32 can be quickly removed from the user and the obstacle, and the cleaning is quickly performed. You can continue working. Moreover, since the cleaner main body 21 and the operation handle part 30 can be stored separately, they can be stored separately in two small storages. Note that both the fitting portions 71 and 72 are not necessarily required, and the same effect can be obtained by using only one of them.
