清掃部材92は、例えば軟質の合成樹脂などにより形成された毛ブラシなどであり、回転体台91の外周面から回転体台91の軸方向に沿って螺旋状に、かつ、回転体台91の径方向に向けて壁状に突出している。そして、この清掃部材92は、回転軌道が回転ブラシ12の回転軌道であるブラシ部材82およびブレード部材83の回転軌道と前側下部にて交差すなわちオーバラップし、かつ、前蓋23の前蓋本体71の溝部75と接触するように設けられている。   The cleaning member 92 is, for example, a bristle brush formed of a soft synthetic resin or the like, spirally from the outer peripheral surface of the rotating body base 91 along the axial direction of the rotating body base 91, and It protrudes in the shape of a wall in the radial direction. The cleaning member 92 intersects or overlaps the rotation trajectories of the brush member 82 and the blade member 83 whose rotation trajectory is the rotation trajectory of the rotary brush 12 at the front lower portion, and the front lid main body 71 of the front lid 23. It is provided so as to be in contact with the groove portion 75 of this.

また、各受板93は、ベルト87の背面すなわち外面側が、一方の受板93の外周面の下部に接触するように配設されている。このため、このベルト87により、回転体13は、共通のモータ14の駆動力によって、回転ブラシ12と反対方向に回転するように構成されている。さらに、各受板93は、回転ブラシ12の受板84，85よりも径寸法が小さく形成されている。このため、回転体13は、回転ブラシ12よりも高速に回転されるように構成されている。そして、この回転により、回転体13は、清掃部材92が回転ブラシ12の各部材82，83と接触して、これら部材82，83に付着した塵埃を除去するとともに、回転ブラシ12の回転方向に応じて、清掃部材92が前蓋23の前蓋本体71の溝部75と接触して前蓋23を前後に摺動させるように構成されている。   Each receiving plate 93 is arranged such that the back surface, that is, the outer surface side of the belt 87 is in contact with the lower part of the outer peripheral surface of one receiving plate 93. Therefore, the belt 87 is configured to rotate the rotating body 13 in the direction opposite to the rotating brush 12 by the driving force of the common motor 14. Further, each receiving plate 93 is formed to have a smaller diameter than the receiving plates 84 and 85 of the rotary brush 12. For this reason, the rotating body 13 is configured to be rotated at a higher speed than the rotating brush 12. As a result of this rotation, the rotating body 13 causes the cleaning member 92 to come into contact with the members 82 and 83 of the rotating brush 12 to remove dust adhering to these members 82 and 83, and in the rotational direction of the rotating brush 12. Accordingly, the cleaning member 92 is configured to come into contact with the groove portion 75 of the front lid body 71 of the front lid 23 and slide the front lid 23 back and forth.

次に、上記一実施の形態の動作を説明する。   Next, the operation of 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を把持して床面上で床ブラシ９を前後に走行させ、吸込口41から床面の塵埃を吸い込む。   Then, the operator grips the grip portion 7, causes the floor brush 9 to travel forward and backward on the floor surface, and sucks dust on the floor surface from the suction port 41.

このとき、床ブラシ９の方向検出手段により床ブラシ９の走行方向が検出されて制御手段に出力され、この制御手段がモータ14を床ブラシ９の走行方向に応じて回転駆動させる。   At this time, the traveling direction of the floor brush 9 is detected by the direction detecting unit of the floor brush 9 and output to the control unit, and the control unit rotates the motor 14 in accordance with the traveling direction of the floor brush 9.

例えば、図１に示すように、床ブラシ９を前進させた際には、モータ14が前方向に回転することで、ベルト87により駆動力が伝達されて回転ブラシ12が前方向に回転し、床面上の塵埃を各部材82，83により掻き取る。   For example, as shown in FIG. 1, when the floor brush 9 is advanced, the motor 14 rotates in the forward direction, so that the driving force is transmitted by the belt 87 and the rotary brush 12 rotates in the forward direction. Dust on the floor is scraped off by the members 82 and 83.

このとき、ベルト87の背面に受板93が接触している回転体13は、回転ブラシ12と逆方向である後方向に回転し、清掃部材92が前蓋23の前蓋本体71の溝部75に次々と接触することで前蓋23を後方へと移動させることにより、閉塞部72が前側吸込口61を閉塞する量が減少して前側吸込口61の開口量が増加し（開口状態）、床ブラシ９の回転清掃体室31の真空度が減少して、床ブラシ９が床面に吸い付くことなく前側に位置する床面上の塵埃を前側吸込口61から吸い込む。   At this time, the rotating body 13 in which the receiving plate 93 is in contact with the back surface of the belt 87 rotates in the rearward direction opposite to the rotating brush 12, and the cleaning member 92 is the groove portion 75 of the front lid main body 71 of the front lid 23. By moving the front lid 23 rearward by contact with each other one after another, the amount by which the blocking portion 72 blocks the front suction port 61 decreases and the opening amount of the front suction port 61 increases (open state). The degree of vacuum in the rotary cleaning body chamber 31 of the floor brush 9 is reduced, and the dust on the floor surface located on the front side is sucked from the front suction port 61 without the floor brush 9 sucking the floor surface.

同時に、回転体13の清掃部材92は、その先端部が回転ブラシ12の各部材82，83の先端部などに叩き付けられることで、回転ブラシ12の回転を補助するとともに、これら部材82，83の先端部に付着した塵埃を叩き落す。   At the same time, the cleaning member 92 of the rotator 13 assists in the rotation of the rotating brush 12 by the tip of the member being struck against the tip of the members 82 and 83 of the rotating brush 12, and the members 82 and 83 Tap off dust adhering to the tip.

一方、図２に示すように、床ブラシ９を後退させた際には、モータ14が後方向に回転することで、ベルト87により駆動力が伝達されて回転ブラシ12が後方向に回転し、床面上の塵埃を各部材82，83により掻き取る。   On the other hand, as shown in FIG. 2, when the floor brush 9 is moved backward, the motor 14 rotates in the backward direction, so that the driving force is transmitted by the belt 87 and the rotating brush 12 rotates in the backward direction. Dust on the floor is scraped off by the members 82 and 83.

このとき、ベルト87の背面に受板93が接触している回転体13は、回転ブラシ12と逆方向である前方向に回転し、清掃部材92が前蓋23の前蓋本体71の溝部75に次々と接触することで前蓋23を前方へと移動させることにより、閉塞部72が前側吸込口61を閉塞する量が増加して前側吸込口61の開口量が減少し（閉口状態）、床ブラシ９の回転清掃体室31の真空度が増加して、床面上の塵埃の吸込口41からの吸込効率を向上する。   At this time, the rotating body 13 in which the receiving plate 93 is in contact with the back surface of the belt 87 rotates in the forward direction, which is the opposite direction to the rotating brush 12, and the cleaning member 92 is the groove portion 75 of the front lid body 71 of the front lid 23. By moving the front lid 23 forward by contact with each other one after another, the amount by which the blocking portion 72 blocks the front suction port 61 increases and the opening amount of the front suction port 61 decreases (closed state). The degree of vacuum in the rotary cleaning body chamber 31 of the floor brush 9 is increased, and the suction efficiency from the dust suction port 41 on the floor surface is improved.

回転体13の清掃部材92は、前進時と同様に、その先端部が回転ブラシ12の各部材82，83の先端部などに叩き付けられることで、回転ブラシ12の回転を補助するとともに、これら部材82，83の先端部に付着した塵埃を叩き落す。   The cleaning member 92 of the rotating body 13 assists the rotation of the rotating brush 12 by the tip of the cleaning member 92 being struck against the tips of the members 82 and 83 of the rotating brush 12 in the same way as when moving forward. Tap off the dust adhering to the tips of 82 and 83.

すなわち、床ブラシ９の前進および後退に応じて、回転体13が前側吸込口61を上記開口状態と上記閉口状態とに切り換える。   That is, as the floor brush 9 moves forward and backward, the rotating body 13 switches the front suction port 61 between the open state and the closed state.

そして、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。   Then, after passing through the extension pipe 8 and the hose body 4 sequentially from the floor brush 9, the dust is guided to the main body suction port 3 of the cleaner body 1 and is collected in the cleaner body 1 (not shown). Collected in a dust pack.

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。   The air in which the dust is collected is sucked into the electric blower 2 to become exhaust air, and is exhausted from an exhaust port (not shown) of the cleaner body 1 to the outside.

上述したように、上記一実施の形態によれば、床ブラシ９の前進時には、回転体13の回転により前蓋23を開口方向である後方向に移動させて前側吸込口61の開口量を増大させるため、前側吸込口61の開口量が増加して真空度が減少することで床面への吸い付きが抑制され、良好な操作性を確保できるとともに、床ブラシ９の後退時には、回転体13の回転により前蓋23を閉口方向である前方向に移動させて前側吸込口61の開口量を減少させるため、前側吸込口61の開口量が減少して真空度が向上することで吸込効率を向上できる。   As described above, according to the above-described embodiment, when the floor brush 9 moves forward, the front lid 23 is moved in the rearward direction by the rotation of the rotating body 13 to increase the opening amount of the front suction port 61. Therefore, the amount of opening of the front suction port 61 is increased and the degree of vacuum is reduced, so that the suction to the floor surface is suppressed, and good operability can be secured. To reduce the opening amount of the front suction port 61 by moving the front lid 23 in the forward direction, which is the closing direction, thereby reducing the opening amount of the front suction port 61 and improving the degree of vacuum. It can be improved.

すなわち、作業者が押し動作をする床ブラシ９の前進時には、床ブラシ９が床面に吸い付くと操作性が悪化してしまうので、回転体13により前蓋23を後方に移動させることで前側吸込口61の開口量を増加させることにより、床ブラシ９の下面の真空度が低減して操作性が向上し、かつ、前側吸込口61から床ブラシ９の前側に位置する固形物などの塵埃を押すことなく吸い込むことができるなど、使い勝手を向上できる。   That is, when the floor brush 9 is pushed forward by the operator, if the floor brush 9 is attracted to the floor surface, the operability deteriorates. By increasing the opening amount of the suction port 61, the degree of vacuum on the lower surface of the floor brush 9 is reduced and the operability is improved, and dust such as solid matter located on the front side of the floor brush 9 from the front suction port 61 Usability can be improved by being able to inhale without pressing.

一方、作業者が引き動作をする床ブラシ９の後退時には、床ブラシ９が床面に多少吸い付いても操作性が気になることがないから、回転体13により前蓋23を後方に移動させることで前側吸込口61の開口量を増加させることにより、床ブラシ９の下面の真空度が増加して塵埃を吸い上げる力すなわち吸込効率が向上し、掃除性能を向上できる。   On the other hand, when the floor brush 9 that the operator pulls is retracted, the operability does not matter even if the floor brush 9 is attracted to the floor surface. By increasing the opening amount of the front suction port 61, the degree of vacuum on the lower surface of the floor brush 9 is increased, the force for sucking up dust, that is, the suction efficiency is improved, and the cleaning performance can be improved.

また、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、床ブラシ９の後退時に回転ブラシ12を後方向に回転させるモータ14の駆動を利用して回転ブラシ12と反対方向に回転する回転体13により前蓋23を前後に摺動させる構成としたことにより、回転ブラシ12の回転により床ブラシ９の走行を補助できるだけでなく、回転体13が床面に接触しないことでこの回転体13も走行負荷となることがなく、床ブラシ９の操作性をより向上できる。   Further, the rotating brush 12 is rotated forward when the floor brush 9 is advanced, and is rotated in the opposite direction to the rotating brush 12 by using the drive of the motor 14 that rotates the rotating brush 12 backward when the floor brush 9 is retracted. The configuration in which the front lid 23 is slid back and forth by the rotating body 13 not only assists the running of the floor brush 9 by the rotation of the rotating brush 12, but also the rotating body 13 does not contact the floor surface. 13 also does not become a traveling load, and the operability of the floor brush 9 can be further improved.

しかも、床ブラシ９の後退時には、回転ブラシ12が後方へと回転することで、床面上の塵埃を前方に飛散させてしまうおそれがあるから、床ブラシ９の後退時に前側吸込口61の開口量を減少させることで、塵埃の前方向への飛散を確実に防止できる。   In addition, when the floor brush 9 is retracted, the rotating brush 12 is rotated rearward so that dust on the floor surface may be scattered forward. Therefore, when the floor brush 9 is retracted, the front suction port 61 is opened. By reducing the amount, dust can be reliably prevented from scattering in the forward direction.

さらに、回転体台91から突設された毛ブラシなどの可撓性を有する清掃部材92により前蓋23を摺動させるため、前蓋23が前方に摺動して蓋ストッパリブ77が上ケース部59の挿入穴65の縁部に保持凸部64の後部で接触して位置が規制された状態、あるいは前蓋23が後方に摺動して前蓋本体71の後端部がストッパリブ63に接触して位置が規制された状態などで清掃部材92が前蓋23に継続的に接触しても、各リブ63，77に必要以上の負荷を与えて破損したり、あるいは清掃部材92自身が破損したりすることを防止できる。   Further, since the front lid 23 is slid by the flexible cleaning member 92 such as a bristle brush protruding from the rotating body base 91, the front lid 23 slides forward and the lid stopper rib 77 is formed in the upper case portion. The rear end of the holding projection 64 is in contact with the edge of the insertion hole 65 of 59 and the position is regulated, or the front lid 23 slides backward and the rear end of the front lid body 71 contacts the stopper rib 63. Even if the cleaning member 92 continuously contacts the front lid 23 in a state where the position is regulated, the ribs 63 and 77 are damaged by applying an excessive load, or the cleaning member 92 itself is damaged. Can be prevented.

すなわち、例えばギアなどを介して前蓋23を前後に摺動させる構成では、前蓋23の前後位置が規制された際にギアなどに負荷が加わり、ギアなどが破損してしまうおそれがあるのに対して、本実施の形態のように可撓性を有する清掃部材92の接触により前蓋23を前後に摺動させる構成では、前蓋23の前後位置が規制されても前蓋23および清掃部材92などを破損するおそれがない。   That is, for example, in a configuration in which the front lid 23 is slid back and forth via a gear or the like, when the front and rear position of the front lid 23 is restricted, a load is applied to the gear or the like, and the gear or the like may be damaged. On the other hand, in the configuration in which the front lid 23 is slid back and forth by the contact of the flexible cleaning member 92 as in the present embodiment, the front lid 23 and the cleaning are performed even if the front-rear position of the front lid 23 is restricted. There is no possibility of damaging the member 92 or the like.

また、清掃部材92を回転体台91の長手方向である軸方向に螺旋状に設けることで、回転体13の回転時に清掃部材92が連続的に前蓋23に接触するため、回転体13の回転力を前蓋23に確実に伝達し、前蓋23を前後方向へと円滑に摺動させることが可能になる。   Further, by providing the cleaning member 92 in a spiral shape in the axial direction that is the longitudinal direction of the rotating body base 91, the cleaning member 92 continuously contacts the front lid 23 when the rotating body 13 rotates. The rotational force can be reliably transmitted to the front lid 23, and the front lid 23 can be smoothly slid in the front-rear direction.

なお、上記一実施の形態において、床ブラシ９および掃除機本体１の細部の構成は、上記構成に限定されるものではない。 Incidentally, in the embodiment described above, the configuration of the floor brush 9 and the cleaner body 1 details are not intended to be limited to the above configuration.

さらに、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、その他、掃除機本体１と床ブラシ９とが一体化された自走式の電気掃除機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。   Furthermore, the vacuum cleaner is not limited to the canister type vacuum cleaner, but is an upright type in which the floor brush 9 is directly formed on the lower surface of the vacuum cleaner body 1. In addition, the vacuum cleaner body 1 and the floor brush 9 are integrated. Even a self-propelled electric vacuum cleaner or a handy type can be used correspondingly.
