Description

本発明は、被掃除面に接地可能にケース体に設けられた進行方向検知手段を有する電気掃除機の吸込口体およびこれを備えた電気掃除機に関する。   The present invention relates to a suction port body of a vacuum cleaner having a traveling direction detection means provided in a case body so as to be groundable on a surface to be cleaned, and a vacuum cleaner including the same.

従来、この種の電気掃除機の吸込口体としての床ブラシは、床面に対向する下面に吸込口が開口形成された横長のケース体を備えている。このケース体内には、吸込口に臨んで回転ブラシが回転可能に設けられている。また、ケース体内には、回転ブラシを回転駆動可能なモータが収容されている。さらに、ケース体の下面には、この床ブラシが床面に接触しているかどうかを検知する検知手段が設けられている。この検知手段は、床面と接触可能な車輪を備えている。そして、この検知手段は、ケース体の下面を下側に向けた状態でケース体に対して進退可能となり、床ブラシを床面に接触させた際にモータの駆動をオンさせて回転ブラシを駆動可能とするとともに、ケース体を上下逆にした状態では、ケース体に対して突出状態を維持して、モータをオンさせないようにする、いわゆる安全装置に利用される（例えば、特許文献１参照。）。   2. Description of the Related Art Conventionally, a floor brush as a suction port body of this type of electric vacuum cleaner includes a horizontally long case body in which a suction port is formed to open on a lower surface facing the floor surface. A rotating brush is rotatably provided in the case body so as to face the suction port. A motor capable of rotating the rotary brush is housed in the case body. Furthermore, a detecting means for detecting whether or not the floor brush is in contact with the floor surface is provided on the lower surface of the case body. The detection means includes a wheel that can contact the floor surface. This detection means can be moved forward and backward with respect to the case body with the lower surface of the case body facing downward, and when the floor brush is brought into contact with the floor surface, the motor is turned on to drive the rotating brush. In addition, in a state in which the case body is turned upside down, it is utilized for a so-called safety device that maintains a protruding state with respect to the case body and prevents the motor from being turned on (see, for example, Patent Document 1). ).

また、床面に接触するレバーをケース体の下面から下方に向けて突出させた検知手段が、このレバーの傾斜方向が床ブラシの進退方向に応じて傾斜方向が切り換わることでモータの駆動方向を切り換えてオンさせるとともに、床ブラシが床面に対して非接触状態となった際にレバーが中立位置に維持されてモータの駆動をオフさせる構成も知られている（例えば、特許文献２参照。）。
特開２００１−５７９５３号公報（第３−４頁、図１） 特開平７−２４１２６４号公報（第２−３頁、図１） In addition, the detection means in which the lever that contacts the floor surface protrudes downward from the lower surface of the case body changes the inclination direction of the lever in accordance with the advancing / retreating direction of the floor brush, thereby driving the motor. There is also known a configuration in which the lever is maintained in a neutral position and the motor is turned off when the floor brush is in a non-contact state with respect to the floor surface (for example, see Patent Document 2). .)

しかしながら、上述の特許文献１記載の電気掃除機の吸込口体では、検知手段の床面に接触する部分が車輪であることにより、床面上に人髪、あるいはペットの毛などの毛ごみがある場合に床ブラシを前後に走行させて掃除をすると、検知手段の車輪の回転軸に毛ごみが絡み付くとう問題点を有している。   However, in the suction port body of the electric vacuum cleaner described in Patent Document 1 described above, the portion of the detection means that contacts the floor surface is a wheel, so that hair such as human hair or pet hair is present on the floor surface. In some cases, when the floor brush is moved forward and backward for cleaning, there is a problem that hairs get entangled with the rotating shaft of the wheel of the detecting means.

そして、回転軸に毛ごみが絡み付くと、この毛ごみの除去が容易でなく、また、作業者が毛ごみに触れなければならず衛生的でないなど、メンテナンス性が良好でない。   If the hair gets entangled with the rotary shaft, the removal of the hair is not easy, and maintenance is not good because the operator must touch the hair and it is not hygienic.

一方、上述の特許文献２記載の電気掃除機の吸込口体では、毛ごみなどの検知手段への絡み付きは防止できるものの、レバーと床面との接触抵抗により床ブラシの前後方向への操作が重くなるため、操作性が良好でないという問題点を有している。   On the other hand, in the suction mouth of the electric vacuum cleaner described in Patent Document 2 described above, entanglement of the detection means such as hair dust can be prevented, but the operation of the floor brush in the front-rear direction is performed by the contact resistance between the lever and the floor surface. Since it becomes heavy, it has a problem that operability is not good.

本発明は、このような点に鑑みなされたもので、良好なメンテナンス性および操作性を確保するとともに、進行方向検知手段による検知を確実にした電気掃除機の吸込口体およびこれを備えた電気掃除機を提供することを目的とする。   The present invention has been made in view of such a point, and while ensuring good maintainability and operability, the suction port body of an electric vacuum cleaner that has been reliably detected by the traveling direction detection means, and an electric device including the same The purpose is to provide a vacuum cleaner.

One of the raised cloths selectively contacts the surface to be cleaned, and is maintained in a neutral position when the raised cloth is not in contact with the surface to be cleaned.

また、本発明は、進行方向検知手段が、ケース体の進行方向に対応するいずれかの起毛布が選択的に被掃除面に接触してケース体の進行方向を検知するものである。   Further, according to the present invention, the traveling direction detection means detects any traveling direction of the case body when any raised cloth corresponding to the traveling direction of the case body selectively contacts the surface to be cleaned.

本発明によれば、ケース体の被掃除面での進退に対応して、ケース体の進行方向に対応する進行方向検知手段のいずれかの起毛布が選択的に被掃除面に接触することで、進行方向検知手段の被掃除面に対する接触抵抗を低減して良好な操作性を確保でき、かつ、塵埃が進行方向検知手段に絡み付くことがなく、良好なメンテナンス性を確保できるとともに、起毛布の被掃除面への非接触状態では進行方向検知手段が中立位置に維持されることで、進行方向検知手段により被掃除面への接触状態を確実に検知できる。   According to the present invention, in response to advancing and retreating of the case body on the surface to be cleaned, any raised cloth of the traveling direction detection means corresponding to the traveling direction of the case body selectively contacts the surface to be cleaned. In addition, the contact resistance of the traveling direction detecting means to the surface to be cleaned can be reduced to ensure good operability, and dust can be prevented from getting entangled with the traveling direction detecting means. In the non-contact state with respect to the surface to be cleaned, the traveling direction detection means is maintained at the neutral position, so that the contact state with the surface to be cleaned can be reliably detected by the traveling direction detection means.

また、本発明によれば、ケース体の被掃除面での進退に対応して、ケース体の進行方向に対応する進行方向検知手段のいずれかの起毛布が選択的に被掃除面に接触することで、進行方向検知手段の被掃除面に対する接触抵抗を低減して良好な操作性を確保でき、かつ、塵埃が進行方向検知手段に絡み付くことがなく、良好なメンテナンス性を確保できるとともに、起毛布の被掃除面への選択的な接触により、進行方向検知手段にてケース体の進行方向を確実に検知できる。   Further, according to the present invention, in response to advancing and retreating of the case body on the surface to be cleaned, any raised cloth of the traveling direction detecting means corresponding to the traveling direction of the case body selectively contacts the surface to be cleaned. As a result, the contact resistance of the traveling direction detecting means with respect to the surface to be cleaned can be reduced to ensure good operability, and the dust can be prevented from getting entangled with the traveling direction detecting means. By the selective contact of the blanket with the surface to be cleaned, the traveling direction of the case body can be reliably detected by the traveling direction detection means.

次に、上記一実施の形態による掃除動作を説明する。   Next, the cleaning operation according to the above embodiment will be described.

まず、作業者は、掃除機本体１の本体吸込口３に、ホース体４、延長管８および床ブラシ９を順次連通接続する。   First, the worker sequentially connects the hose body 4, the extension pipe 8, and the floor brush 9 to the main body suction port 3 of the cleaner body 1.

さらに、作業者が、掃除機本体１から電源コードを引き出して図示しないコンセントに接続した後、把持部７を把持して所定の設定ボタン６を操作すると、この設定ボタン６により設定された動作モードに応じて電動送風機２が駆動される。   Further, when the operator pulls out the power cord from the cleaner body 1 and connects it to an outlet (not shown), and then operates the predetermined setting button 6 by holding the holding portion 7, the operation mode set by the setting button 6 is set. Accordingly, the electric blower 2 is driven.

そして、作業者は、把持部７を把持し、床面上に接地した床ブラシ９を前後に走行させて、吸込口26から床面の塵埃を吸い込むとともに、床面の種類に応じて所定の設定ボタン６を適宜操作し、回転ブラシ12が回転駆動させる。   Then, the operator grips the grip portion 7 and runs the floor brush 9 grounded on the floor surface back and forth to suck in dust on the floor surface from the suction port 26, and according to the type of the floor surface. By appropriately operating the setting button 6, the rotary brush 12 is driven to rotate.

ここで、床ブラシ９を前進させている際には、床ブラシ９とともに軸支穴72内で前方向にスライドして前側軸支部72aで保持された揺動軸61を中心として、図４(a)に示すように、切換アーム63の突出腕部63aが挿通軸支穴73に沿って前方向に移動して前側挿通軸支部73aに保持され、かつ、切換シャフト63が摺動孔75にて前方向に移動して前側連続保持部75bに保持されて、安全体本体41が前方向に倒れるようにシーソー状に揺動し、毛の方向が後方向に沿っている起毛布86が床面に接地して床面上の塵埃を掻き取る。   Here, when the floor brush 9 is being advanced, the rocker 61 is slid forward in the shaft support hole 72 together with the floor brush 9 and is centered on the swing shaft 61 held by the front shaft support portion 72a. As shown in a), the protruding arm portion 63a of the switching arm 63 moves forward along the insertion shaft supporting hole 73 and is held by the front insertion shaft supporting portion 73a, and the switching shaft 63 is inserted into the sliding hole 75. Is moved to the front and is held by the front continuous holding portion 75b, swings like a seesaw so that the safety body main body 41 is tilted forward, and a raised cloth 86 whose hair direction is in the rear direction is a floor. Touch the surface and scrape the dust on the floor.

そして、安全体本体41の回動に伴い、切換アーム63の腕部63eが上方に回動してスイッチ44のレバー44aを押し込むことでスイッチ44がオンされ、このスイッチ44が接続された制御手段が床ブラシ９の進行方向を検知し、回転ブラシ12を回転駆動させる際には、制御手段がモータ13を介して回転ブラシ12の回転方向、あるいは回転速度を床ブラシ９の進行方向に応じて制御する。   As the safety body 41 rotates, the arm portion 63e of the switching arm 63 rotates upward and pushes the lever 44a of the switch 44, so that the switch 44 is turned on, and the control means to which the switch 44 is connected. When detecting the traveling direction of the floor brush 9 and rotating the rotating brush 12, the control means controls the rotational direction or rotational speed of the rotating brush 12 via the motor 13 according to the traveling direction of the floor brush 9. Control.

例えば、この床ブラシ９の前進時に、回転ブラシ12を前方向に回転させる制御をする際には、床ブラシ９の操作性が向上し、回転ブラシ12を後方向に回転させる際には、回転ブラシ12による床面の掃除性能が向上する。   For example, when controlling the rotary brush 12 to rotate forward when the floor brush 9 moves forward, the operability of the floor brush 9 is improved, and when rotating the rotary brush 12 backward, the rotary brush 12 is rotated. Floor cleaning performance with the brush 12 is improved.

一方、床ブラシ９を後進させている際には、床ブラシ９とともに軸支穴72内で後方向にスライドして後側軸支部72bで保持された揺動軸61を中心として、図４(b)に示すように、切換アーム63の突出腕部63aが挿通軸支穴73に沿って後方向に移動して後側挿通軸支部73bに保持され、かつ、切換シャフト65が摺動孔75にて後方向に移動して後側連続保持部75cに保持されて、安全体本体41が後方向に倒れるようにシーソー状に揺動し、毛の方向が前方向に沿っている起毛布89が床面に接地して床面上の塵埃を掻き取る。   On the other hand, when the floor brush 9 is being moved backward, the swinging shaft 61 that slides rearward in the shaft support hole 72 together with the floor brush 9 and is held by the rear shaft support portion 72b is shown in FIG. As shown in b), the protruding arm portion 63a of the switching arm 63 moves rearward along the insertion shaft support hole 73 and is held by the rear insertion shaft support portion 73b, and the switching shaft 65 is moved to the sliding hole 75. Is moved to the rear and held by the rear continuous holding portion 75c, and the safety body 41 swings in a seesaw shape so that it falls backward, and the direction of the hair is the raised fabric 89 along the front. Touches the floor and scrapes the dust on the floor.

そして、安全体本体41の回動に伴い、切換アーム63の腕部63dが上方に回動してスイッチ45のレバー45aを押し込むことでスイッチ45がオンされ、このスイッチ45が接続された制御手段が床ブラシ９の進行方向を検知し、回転ブラシ12を回転駆動させる際には、制御手段が床ブラシ９の進行方向に応じて、例えばモータ13を介して回転ブラシ12の回転方向を床ブラシ９の前進時と反対方向に制御したり、回転ブラシ12の回転速度を制御したりする。   As the safety body 41 rotates, the arm portion 63d of the switching arm 63 rotates upward and pushes the lever 45a of the switch 45, so that the switch 45 is turned on, and the control means to which the switch 45 is connected. When detecting the traveling direction of the floor brush 9 and rotating the rotary brush 12, the control means determines the rotational direction of the rotating brush 12 via the motor 13, for example, according to the traveling direction of the floor brush 9. 9 is controlled in the opposite direction to that during forward movement, or the rotational speed of the rotary brush 12 is controlled.

例えば、この床ブラシ９の後進時に、回転ブラシ12を前方向に回転させる制御をする際には、回転ブラシ12による掃除性能が向上し、回転ブラシ12を後方向に回転させる際には、床ブラシ９の操作性が向上する。   For example, when the rotary brush 12 is controlled to rotate forward when the floor brush 9 moves backward, the cleaning performance of the rotary brush 12 is improved, and when the rotary brush 12 is rotated backward, the floor brush 9 The operability of the brush 9 is improved.

そして、回転駆動された回転ブラシ12は、例えば床面が絨毯などの場合には、清掃部材36が床面の塵埃を掻き出し、床面がフローリングなどの場合には、清掃部材36が床面を磨く。   When the rotating brush 12 is driven to rotate, for example, when the floor surface is a carpet or the like, the cleaning member 36 scrapes off dust on the floor surface, and when the floor surface is flooring or the like, the cleaning member 36 cleans the floor surface. polish.

また、床ブラシ９を床面から離間した際には、レバー44a，45aの付勢力により安全装置14の安全体本体41が中立状態に維持されることで、各スイッチ44，45がオフされて安全装置14が床ブラシ９の床面への非接地状態を検知し、制御手段がモータ13すなわち回転ブラシ12の回転駆動を停止させる。   Further, when the floor brush 9 is separated from the floor surface, the safety body main body 41 of the safety device 14 is maintained in a neutral state by the biasing force of the levers 44a and 45a, so that the switches 44 and 45 are turned off. The safety device 14 detects the non-grounding state of the floor brush 9 on the floor surface, and the control means stops the rotation drive of the motor 13, that is, the rotary brush 12.

そして、床ブラシ９の吸込口26から空気とともに吸い込まれた塵埃は、床ブラシ９から延長管８およびホース体４を順次通過した後、掃除機本体１の本体吸込口３へと導かれて、この掃除機本体１内に収容された図示しない集塵パックに捕集される。   And the dust sucked together with air from the suction port 26 of the floor brush 9 is sequentially guided from the floor brush 9 to the main body suction port 3 of the cleaner body 1 after passing through the extension pipe 8 and the hose body 4. The dust is collected in a dust collection pack (not shown) accommodated in the cleaner body 1.

この後、塵埃が捕集された空気は、電動送風機２へと吸気されて排気風となり、掃除機本体１の図示しない排気口から外部へと排気される。   Thereafter, the air in which the dust is collected is sucked into the electric blower 2 to become exhaust air, and is exhausted to the outside from an exhaust port (not shown) of the cleaner body 1.

また、図５に示すように、床ブラシ９を上下反転させると、切換シャフト65がシャフト挿通孔66および摺動孔75の長孔部75aに沿って落下することにより、安全体本体41が側壁部71，71に固定されて安全体本体41の前後方向への揺動が規制され、安全装置14の安全体本体41が中立状態に維持される。   Further, as shown in FIG. 5, when the floor brush 9 is turned upside down, the switching shaft 65 falls along the shaft insertion hole 66 and the long hole portion 75a of the sliding hole 75, so that the safety body main body 41 becomes the side wall. The safety body main body 41 is fixed to the portions 71 and 71 and the swinging of the safety body main body 41 in the front-rear direction is restricted, and the safety body main body 41 of the safety device 14 is maintained in a neutral state.

上述したように、上記一実施の形態では、床ブラシ９のケース体11の床面での進退に対応して、このケース体11の進行方向に対応する安全装置14のいずれかの起毛布86，89が選択的に床面に接触する構成とした。   As described above, in the above-described embodiment, the raised cloth 86 of any of the safety devices 14 corresponding to the traveling direction of the case body 11 corresponding to the advancement / retraction of the floor brush 9 on the floor surface of the case body 11. , 89 selectively contact the floor.

具体的には、ケース体11の床面での前後方向への進退に従って安全装置14の安全体本体41が揺動し、このケース体11の進行方向に対応する起毛布86，89が選択的に床面に接触する構成とした。   Specifically, the safety body main body 41 of the safety device 14 swings as the case body 11 moves back and forth on the floor surface, and the raised cloths 86 and 89 corresponding to the traveling direction of the case body 11 are selectively used. It was set as the structure which contacts a floor surface.

この結果、安全装置14の床面に対する接触抵抗を低減して良好な操作性を確保できるとともに、安全装置14にてケース体11の進行方向を確実に検知でき、また、例えば安全装置に車輪などを用いる従来の場合と異なり、人髪、あるいはペットの毛などの毛ごみ、あるいは糸ごみなどが安全装置14に絡み付くことがないから、これらのごみを安全装置14から除去する手間を省略でき、良好なメンテナンス性を確保できるとともに、作業者がごみに触れたりすることもなく、衛生的となる。   As a result, the contact resistance to the floor surface of the safety device 14 can be reduced to ensure good operability, and the traveling direction of the case body 11 can be reliably detected by the safety device 14, and for example, the safety device has wheels or the like. Unlike conventional cases using hair, human hair, pet hair and other lint, or thread litter, etc. do not get entangled with the safety device 14, so the trouble of removing these litter from the safety device 14 can be eliminated, Good maintainability can be ensured, and the operator does not touch the waste and is hygienic.

さらに、例えば床ブラシ９を床面から持ち上げた際など、起毛布86，89の床面への非接触状態では安全装置14の安全体本体41が中立位置に維持されることで、安全装置14により、床ブラシ９の床面への接触状態を確実に検知できる。   Furthermore, when the floor brush 9 is lifted from the floor surface, for example, the safety body main body 41 of the safety device 14 is maintained in the neutral position when the raised cloths 86 and 89 are not in contact with the floor surface. Thus, the contact state of the floor brush 9 with the floor surface can be reliably detected.

そして、スイッチ44，45のレバー44a，45aの付勢力により安全装置14の安全体本体41が中立位置に維持されることにより、この安全体本体41を中立位置に維持するための部材などを別個に設ける必要がなく、構成を簡略化できる。   Then, the safety body main body 41 of the safety device 14 is maintained in the neutral position by the biasing force of the levers 44a and 45a of the switches 44 and 45, so that members for maintaining the safety body main body 41 in the neutral position are separately provided. Therefore, the configuration can be simplified.

また、安全装置14による床ブラシ９の床面への接触検知および進行方向の検知に従って回転ブラシ12の回転を制御することにより、床ブラシ９の操作に応じて操作性、あるいは掃除性能を向上できる。   Further, by controlling the rotation of the rotating brush 12 according to the detection of the contact of the floor brush 9 to the floor surface and the detection of the traveling direction by the safety device 14, the operability or the cleaning performance can be improved according to the operation of the floor brush 9. .

さらに、安全装置14の安全体本体41が、ケース体11を上下反転させている状態で中立位置に維持されることにより、例えば作業者が床ブラシ９を持ち上げて反転させた際などに安全装置14を操作しても、この安全装置14が揺動せず、スイッチ44，45がオンされて回転ブラシ12が誤って回転することなどを確実に防止できる。   Further, the safety body main body 41 of the safety device 14 is maintained in a neutral position with the case body 11 being turned upside down, so that, for example, when the operator lifts and reverses the floor brush 9, the safety device Even if 14 is operated, the safety device 14 does not swing, and the switches 44 and 45 are turned on and the rotating brush 12 can be reliably prevented from rotating accidentally.

特に、電気掃除機の床ブラシ９は、床面上で前後方向に繰り返し走行させて床面を掃除するものであるから、上記のように安全装置14を構成することで、作業者の掃除作業を安全装置14により確実に検知でき、この検知に応じて回転ブラシ12の駆動などを制御することで、電気掃除機の使い勝手を向上できる。   In particular, the floor brush 9 of the electric vacuum cleaner is repeatedly driven in the front-rear direction on the floor surface to clean the floor surface. Therefore, by configuring the safety device 14 as described above, the operator can perform the cleaning work. Can be reliably detected by the safety device 14, and by controlling the driving of the rotating brush 12 according to this detection, the usability of the electric vacuum cleaner can be improved.

そして、軸支穴72の下端部を略Ｖ字状とすることにより、揺動軸61が軸支穴72の中心部に位置しやすくなるので、床ブラシ９を床面から離間した状態などで揺動軸61が中立位置に復帰し易くなり、安全装置14の誤作動を確実に防止できるとともに、安全装置14の安全体本体41の揺動時には、このＶ字形状に沿って軸支穴72が前後方向に移動し易くなり、円滑に揺動可能となる。   Then, by making the lower end portion of the shaft support hole 72 substantially V-shaped, the swing shaft 61 can be easily located at the center of the shaft support hole 72, so that the floor brush 9 is separated from the floor surface, etc. The swing shaft 61 can easily return to the neutral position, and the malfunction of the safety device 14 can be reliably prevented, and when the safety body 41 of the safety device 14 swings, the shaft support hole 72 extends along this V shape. Becomes easy to move in the front-rear direction, and can swing smoothly.

同様に、挿通軸支穴73および摺動孔75の下端部を、前後方向の中心部が凸状となるように形成することで、切換アーム63の突出腕部63a、あるいは切換シャフト65が床ブラシ９を床面から離間した状態などで中立位置に復帰し易くできる。   Similarly, by forming the lower end portions of the insertion shaft support hole 73 and the sliding hole 75 so that the center portion in the front-rear direction is convex, the protruding arm portion 63a of the switching arm 63 or the switching shaft 65 is fixed to the floor. The brush 9 can be easily returned to the neutral position in a state where the brush 9 is separated from the floor surface.

なお、上記一実施の形態において、スイッチ44，45は、切換アーム63によってレバー44a，45aが押されることでオンオフ状態が切り換わるものであれば、例えばレバー44a，45aが押し込まれた状態でのみオフとなる常閉のスイッチなどとしてもよい。   In the above-described embodiment, the switches 44 and 45 are only in a state where the levers 44a and 45a are pushed in, for example, if the on / off state is switched by the levers 44a and 45a being pushed by the switching arm 63. A normally closed switch that is turned off may be used.

また、１つのスイッチにより上記一実施の形態と同様の作用効果を奏する構成とすることも可能である。   In addition, it is possible to adopt a configuration in which the same operation and effect as in the above-described embodiment can be achieved by one switch.

さらに、安全装置14の検知に応じて、電動送風機２の入力を制御する構成も可能である。この場合には、例えば床ブラシ９の前進時に電動送風機２の入力を抑制するように制御すると、床ブラシ９の床面への吸い付きを低減して操作性を向上でき、また、床ブラシ９の前進時に電動送風機２の入力を増加させるように制御すると、床ブラシ９の吸込性能を向上できる。   Furthermore, the structure which controls the input of the electric blower 2 according to the detection of the safety device 14 is also possible. In this case, for example, if control is performed so as to suppress the input of the electric blower 2 when the floor brush 9 moves forward, the traction of the floor brush 9 to the floor surface can be reduced, and the operability can be improved. If it controls so that the input of the electric blower 2 may be increased at the time of forward movement, the suction performance of the floor brush 9 can be improved.

そして、進行方向検知手段による検知は、他の様々な制御に利用することが可能である。   The detection by the traveling direction detection means can be used for various other controls.

また、進行方向検知手段を床ブラシ９に複数設ける構成とすることも可能である。   It is also possible to employ a configuration in which a plurality of traveling direction detection means are provided on the floor brush 9.

さらに、進行方向検知手段の構成は、上記構成に限定されるものではなく、例えば床ブラシ９の走行方向前側に向けて設けられた起毛布と、後側に向けて設けられた起毛布とをそれぞれ別個の部材とし、これら部材を、床ブラシ９の走行方向の検知に応じて選択的に接地するように上下させる構成など、他の様々な構成が可能である。   Furthermore, the configuration of the traveling direction detection means is not limited to the above configuration, and for example, a raised cloth provided toward the front side in the running direction of the floor brush 9 and a raised cloth provided toward the rear side. Various other configurations are possible, such as a configuration in which each member is a separate member and these members are moved up and down so as to be selectively grounded in response to detection of the traveling direction of the floor brush 9.

そして、電気掃除機としては、キャニスタ型の電気掃除機に限らず、床ブラシ９が掃除機本体１の下面に直接形成されたアップライト型、あるいはハンディ型などであっても対応させて用いることができる。   The vacuum cleaner is not limited to a canister type vacuum cleaner, and the floor brush 9 may be an upright type or a handy type directly formed on the lower surface of the vacuum cleaner body 1. Can do.
