Description

本発明は電気掃除機およびその吸込具に関する。 The present invention relates to a vacuum cleaner and its suction tool.

一般的な床移動型の電気掃除機は、集塵部や電動送風機を備えた掃除機本体にホースを介して延長管を接続し、この延長管の先端に、床面のゴミを吸い込むための吸口体を取り付ける構成である。そして、前記吸口体を用いて十分に掃除できない隙間や棚面などを掃除するために、補助吸込具を用いることができるようにしている。この補助吸込具は、使用したいときに使用者の手元にないと不便であることから、延長管などの部材に取り付けておく構成が提案されている。 A general floor-moving type electric vacuum cleaner connects an extension pipe via a hose to a vacuum cleaner body equipped with a dust collector and an electric blower, and sucks dust on the floor surface into the tip of the extension pipe. It is the structure which attaches a mouthpiece. And in order to clean the clearance gap, shelf surface, etc. which cannot be fully cleaned using the said suction body, it is made possible to use an auxiliary suction tool. Since this auxiliary suction tool is inconvenient if it is not available to the user when it is desired to be used, a configuration in which it is attached to a member such as an extension pipe has been proposed.

しかし、補助吸込具を延長管の外に取り付ける構成では、補助吸込具が邪魔になって作業しにくいものであったり、作業中に、はずれて落ちたりすることがあることから、補助吸込具を延長管の手元側に直列に接続し、延長管をはずすことによって刷毛等が露出し、直ぐに棚面等を清掃することができるように構成した補助吸込具が提案されている。 However, in the configuration where the auxiliary suction tool is attached to the outside of the extension pipe, it may be difficult to work because the auxiliary suction tool is in the way, or it may fall off during the work. There has been proposed an auxiliary suction tool that is connected in series to the proximal side of the extension pipe, and the brush or the like is exposed by removing the extension pipe so that the shelf surface and the like can be cleaned immediately.

後側刷毛台１０２は、図４に示すように、パイプ部材１０１の延長管接続部１０１ｂに延長管２０５を接続するように嵌入することによって、後側刷毛台１０２に取り付けられてパイプ部材１０１の内側に突出する突起部材１０８ａ，１０８ｂが延長管２０５の端縁に押されて後側刷毛台１０２と共に後退する。そして、前側刷毛台１０３に植毛した刷毛１０５の先端までが外ケース１０６の内側に収納される位置まで後退すると、クランプ係合突起１０２ｈ，１０２ｉがクランプ部材１０５の突起部１０５ａに係合して後側刷毛台１０２を後退した状態に保持する。 As shown in FIG. 4, the rear brush table 102 is attached to the rear brush table 102 by being fitted so as to connect the extension pipe 205 to the extension pipe connecting portion 101 b of the pipe member 101. The projecting members 108 a and 108 b projecting inward are pushed by the end edge of the extension pipe 205 and retracted together with the rear brush table 102. Then, when the tip of the brush 105 planted on the front brush table 103 is retracted to the position where it is housed inside the outer case 106, the clamp engagement protrusions 102h and 102i are engaged with the protrusion 105a of the clamp member 105 and then The side brush table 102 is held in a retracted state.

図１１〜図１３は、外ケース１０６を透視した補助吸込具１００の側面図である。 11 to 13 are side views of the auxiliary suction tool 100 as seen through the outer case 106.

図１１は、前側刷毛台１０３が後側刷毛台１０２に真っ直な状態に結合した刷毛部を形成しており、蔓巻ばね１０９ａ〜１０９ｃを圧縮しながらパイプ部材１０１上を後退し、クランプ係合突起１０２ｈ，１０２ｉがクランプ部材１０５の突起部１０５ａに係合して外ケース内に保持されている状態である。 FIG. 11 shows a brush portion in which the front brush base 103 is connected to the rear brush base 102 in a straight state, and retracts on the pipe member 101 while compressing the helical springs 109a to 109c, and the clamp member In this state, the mating protrusions 102 h and 102 i are engaged with the protrusion 105 a of the clamp member 105 and held in the outer case.

図１２は、補助吸込具１００を使用するために刷毛部を前進させて刷毛１０４を外ケースの前方に露出させた状態である。このように刷毛部を前進させるためには、クランプ部材１０５の押しボタン部１０５ｂを押して突起部１０５ａを押し下げて後側刷毛台１０２のクランプ係合突起１０２ｈ，１０２ｉとの係合を解除する。クランプ係合突起１０２ｈ，１０２ｉがクランプ部材１０５の突起部１０５ａから解放された後側刷毛台１０２は、蔓巻ばね１０９ａ〜１０９ｃの伸力によって前側刷毛台１０３と共に前方に押し出されて刷毛１０４を露出させる。後側刷毛台１０２の前進量は、突起部材１０８ａ，１０８ｂがパイプ部材１０１の摺動制限長穴１０１ｄの端部に当接するまでの位置に制限して、刷毛部が抜け出るのを防止する。 FIG. 12 shows a state in which the brush 104 is moved forward in order to use the auxiliary suction tool 100 and the brush 104 is exposed to the front of the outer case. In order to advance the brush portion in this way, the push button portion 105b of the clamp member 105 is pushed to push down the projection portion 105a to release the engagement with the clamp engagement projections 102h and 102i of the rear brush base 102. The rear brush base 102 from which the clamp engaging protrusions 102h and 102i are released from the protrusion 105a of the clamp member 105 is pushed forward together with the front brush base 103 by the tension of the vine springs 109a to 109c to expose the brush 104. Let The amount of advancement of the rear brush base 102 is limited to a position until the protruding members 108a and 108b come into contact with the end of the sliding restriction long hole 101d of the pipe member 101 to prevent the brush portion from coming out.

この状態は、刷毛部における刷毛１０４は、軸方向を向くように、前側刷毛台１０３が後側刷毛台１０２に結合した状態である。 This state is a state in which the front brush base 103 is coupled to the rear brush base 102 so that the brush 104 in the brush portion faces the axial direction.

図１３は、外ケース外に露出するように前進させた刷毛部における刷毛１０４の向きを軸方向に対して約６０度の角度に傾斜（屈曲）させた状態の補助吸込具１００である。このような刷毛１０４の向きの変更（屈曲）は、後側刷毛台１０２に対して嵌着した前側刷毛台１０３を１８０度回転させることによって実現することができる。回転角度を変えることによって屈曲角度も変化する。 FIG. 13 shows the auxiliary suction tool 100 in a state where the direction of the brush 104 in the brush portion advanced so as to be exposed outside the outer case is inclined (bent) at an angle of about 60 degrees with respect to the axial direction. Such a change (bending) of the direction of the brush 104 can be realized by rotating the front brush base 103 fitted to the rear brush base 102 by 180 degrees. The bending angle is also changed by changing the rotation angle.
