Description

本発明は電気掃除機用吸込具及び前記吸込具を用いた電気掃除機に関するものである。 The present invention relates to a vacuum cleaner suction tool and a vacuum cleaner using the suction tool.

近年、家具間等の狭い隙間のゴミや部屋の壁際のゴミを、吸込具を付け替えることなく掃除中に簡単な操作で掃除することができる電気掃除機が要望されていた。その問題を解決するため従来の掃除機では図１９に示す様な構成があった。 In recent years, there has been a demand for an electric vacuum cleaner that can clean dust in a narrow space such as between furniture or near a wall of a room with a simple operation during cleaning without changing the suction tool. In order to solve the problem, the conventional vacuum cleaner has a configuration as shown in FIG.

以下にその構成を図１９、図２０を用いて説明する。 The configuration will be described below with reference to FIGS.

吸込具は、上部枠体１と下部枠体２とにより形成されており、内部に集塵室３を有し前記集塵室３の掃除面方向には下部枠体２に開口４が設けられている。吸込具後部には上部枠体１と下部枠体２によって上下に回動自在にアーム４６が挟持されている。またこのアーム４６は掃除面に対し、上下方向に回動する構成となっている。４７は、延長管４４の接続方向と前記アーム４６との取り付け方向が９０度曲げられた形状をした接続パイプであり、前記アーム４６の上部に垂直方向にかつ周方向に略１８０度回動自在に取り付けられている。 The suction tool is formed by an upper frame body 1 and a lower frame body 2, and has a dust collection chamber 3 therein, and an opening 4 is provided in the lower frame body 2 in the cleaning surface direction of the dust collection chamber 3. ing. An arm 46 is sandwiched between the upper frame 1 and the lower frame 2 so as to be rotatable up and down at the rear part of the suction tool. The arm 46 is configured to rotate in the vertical direction with respect to the cleaning surface. Reference numeral 47 denotes a connection pipe having a shape in which the connection direction of the extension pipe 44 and the mounting direction of the arm 46 are bent by 90 degrees, and can rotate approximately 180 degrees vertically and circumferentially on the upper part of the arm 46. Is attached.

そして接続パイプ４７には、延長管４４が接続され、延長管４４の他端には取手部４８が接続され、取手部４８の後方にはホース４５が接続されている。 An extension pipe 44 is connected to the connection pipe 47, a handle portion 48 is connected to the other end of the extension pipe 44, and a hose 45 is connected to the rear of the handle portion 48.

上記構成より、取手部４８を握る人の前後に歩く姿勢の方向に対し吸込具の長手方向４９が垂直方向にあったものが、取手部を左右に捩ることで、吸込具が左右各方向に略９０度旋回し、吸込具の長手方向４９と前後に歩く姿勢の方向が同方向となり、部屋の壁際のゴミを容易に吸い取ることができ、また吸込具の長手幅の邪魔がなくなるため、家具間等の狭い隙間のゴミも吸込具を付け替えることなく簡単な捩り操作で掃除することができる。 From the above configuration, the longitudinal direction 49 of the suction tool is perpendicular to the direction of walking posture before and after the person gripping the handle portion 48, but by twisting the handle portion left and right, the suction tool is moved in the left and right directions. It turns about 90 degrees, the longitudinal direction 49 of the suction tool is the same as the posture of walking in the front and back, and it is possible to easily suck up dust at the wall of the room, and there is no obstruction of the longitudinal width of the suction tool. It is possible to clean the dust in a narrow gap such as between them with a simple twisting operation without changing the suction tool.

しかしながら、これらの電気掃除機用吸込具は、図１９、図２０に示す様に、アーム４６と接続パイプ４７の中を流れる風が９０度方向に２回も狭い空間５０内で曲げられるため、そこで発生する風切り騒音が大きくなるといった問題を有していた。 However, as shown in FIGS. 19 and 20, these vacuum cleaner suction tools are bent in the narrow space 50 twice in the direction of 90 degrees because the wind flowing in the arm 46 and the connection pipe 47 is bent twice. Therefore, there has been a problem that wind noise generated is increased.

また、構成が複雑となり部品点数も多くなるといった問題も有していた。 In addition, the configuration is complicated and the number of parts is increased.

また、接続パイプ４７が９０度曲げられた形状から、延長管４４の取付位置がアーム４６の回動支点５１より高い位置にありかつ、その高い位置にて接続パイプ４７が左右方向に回動するため、延長管４４操作時の力のベクトル方向が吸込具を直進に押す方向から左右どちらかの方向にズレると、吸込具が接続パイプ４７の回動軸５２を中心にして回転してしまい、掃除時に吸込具が左右にふらついたり回転してしまうといった使い勝手が良くないといった問題も有していた。 Further, since the connection pipe 47 is bent 90 degrees, the attachment position of the extension pipe 44 is higher than the rotation fulcrum 51 of the arm 46, and the connection pipe 47 rotates in the left-right direction at the higher position. For this reason, if the vector direction of the force when operating the extension pipe 44 deviates from the direction in which the suction tool is pushed straight to the left or right, the suction tool rotates around the rotation shaft 52 of the connection pipe 47, There was also a problem that the suction tool fluctuated from side to side or rotated during cleaning, which was not convenient.

本発明は、上記問題を解決するもので、簡単な捩り操作で吸込具が左右各方向に９０度旋回する機構を備えつつ、機能上の使い勝手を良くすることを目的とする。 This invention solves the said problem, and it aims at improving the usability of a function, providing the mechanism in which a suction tool turns 90 degree | times to each direction on either side with simple twist operation.

（実施例１）
以下本発明の第１の実施例を図１〜図４において説明する。 (Example 1)
A first embodiment of the present invention will be described below with reference to FIGS.

吸込具は、上部枠体１と下部枠体２とにより形成されており、内部に集塵室３を有し集塵室３の掃除面方向には下部枠体２に開口４が設けられている。吸込具後部には上部枠体１と下部枠体２によって上下に回動自在に主継手部５が挟持されている。またこの主継手部５は掃除面に対し、略水平方向から略垂直方向まで回動する構成となっている。６は従継手部であり、接続パイプ７を保持しかつ、前記主継手部５とは左右方向に略１８０度回動自在に取り付けられている。８はゴム等の柔軟材料の継手管であり、主継手部５と従継手部６の内部を通り、吸引口９と接続パイプ７とを連結し、集塵通路を形成している。そして接続パイプ７には、延長管４４が接続されている。 The suction tool is formed by an upper frame body 1 and a lower frame body 2, and has a dust collection chamber 3 therein, and an opening 4 is provided in the lower frame body 2 in the cleaning surface direction of the dust collection chamber 3. Yes. A main joint 5 is sandwiched between the upper frame 1 and the lower frame 2 so as to be rotatable up and down at the rear part of the suction tool. The main joint 5 is configured to rotate from a substantially horizontal direction to a substantially vertical direction with respect to the cleaning surface. Reference numeral 6 denotes a secondary joint portion which holds the connection pipe 7 and is attached to the main joint portion 5 so as to be rotatable by about 180 degrees in the left-right direction. Reference numeral 8 denotes a joint pipe made of a flexible material such as rubber, which passes through the inside of the main joint section 5 and the subjoint section 6 and connects the suction port 9 and the connection pipe 7 to form a dust collection passage. An extension pipe 44 is connected to the connection pipe 7.

上記構成よる作用は以下の通りである。 The operation of the above configuration is as follows.

図４に示す様に、吸込具を床面に接地させた状態で、延長管４４を左方向に捩って行くと、従継手部６は左方向に主継手部５は上方向に回動しはじめると同時に、吸込具も左方向に旋回しはじめ、略９０度まで捩った時点で主継手部５は床面に対し略垂直方向に達し、吸込具は左方向に略９０度旋回する。その時、継手管８はゴム等の材料の柔軟性により、曲がりながら集塵通路を確保している。その結果、吸込具の長手方向ａ１０は、延長管４４の長手方向ｃ５３と略平行５４で、人が前後に歩く姿勢の方向とが同方向となっており、部屋の壁際のゴミを容易に吸い取ることができ、また吸込具の長手幅の邪魔がなくなるため、家具間等の狭い隙間のゴミ掃除も簡単な捩り操作ででき、使い勝手が良く、掃除作業の向上を図ることができる。そして、右方向に捩った時も同様な作用が得られる。 As shown in FIG. 4, when the extension pipe 44 is twisted in the left direction with the suction tool grounded to the floor surface, the secondary joint portion 6 rotates in the left direction and the main joint portion 5 rotates in the upward direction. At the same time, the suction tool begins to turn leftward, and when it is twisted to approximately 90 degrees, the main joint portion 5 reaches a direction substantially perpendicular to the floor surface, and the suction tool rotates approximately 90 degrees to the left. . At that time, the joint pipe 8 secures a dust collecting passage while being bent by the flexibility of a material such as rubber. As a result, the longitudinal direction a10 of the suction tool is substantially parallel to the longitudinal direction c53 of the extension pipe 44, and the direction of the posture in which the person walks back and forth is the same direction, so that the dust near the wall of the room is easily sucked. In addition, since the obstruction of the longitudinal width of the suction tool can be eliminated, dust cleaning in a narrow gap between furniture and the like can be performed with a simple twisting operation, which is easy to use and can improve the cleaning work. The same effect can be obtained when twisted in the right direction.

その時また、吸引口９から継手管８を経て接続パイプ７までの連結する集塵通路が、直線上に連通して配置されかつ、継手管８がゴム等の材料の柔軟性により緩やかに曲がるため、従来例図１９に示す様に風の流路を狭い空間５０内で屈曲させることが無いので、風切り騒音を低減でき静音化が図れる。 At that time, the dust collecting passage connected from the suction port 9 through the joint pipe 8 to the connection pipe 7 is arranged in a straight line, and the joint pipe 8 is gently bent due to the flexibility of a material such as rubber. Since the wind passage is not bent in the narrow space 50 as shown in FIG. 19, the wind noise can be reduced and the noise can be reduced.

また、構成がシンプルで部品点数が少なく、組立て易いためコスト低減が図かれる。 In addition, since the configuration is simple, the number of parts is small, and the assembly is easy, the cost can be reduced.

また、この実施例では２軸の関節の場合で説明したが、軸が複数になった場合でも同様の効果が得られることは、容易に推測できるものである。 In this embodiment, the case of a biaxial joint has been described. However, it can be easily estimated that the same effect can be obtained even when there are a plurality of axes.

Next, a second embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

主継手部５には掃除面に対し上下方向に回動する上下回動軸１１と前記上下回動軸１１に直交し左右方向に回動する左右回動軸１２を備えている。 The main joint portion 5 includes a vertical rotation shaft 11 that rotates in the vertical direction with respect to the cleaning surface, and a horizontal rotation shaft 12 that is orthogonal to the vertical rotation shaft 11 and rotates in the horizontal direction.

吸込具の上部枠体１側には、前記主継手部５の上下回動軸１１を組み付け、主継手部５は略水平方向から略垂直方向まで回動する。主継手部５の左右回動軸１２には、接続パイプ７を保持した従継手部６を組み付け、左右方向に略１８０度回動する構成となっている。そして、８はゴム等の柔軟材料の継手管であり、主継手部５と従継手部６の内部を通り、吸引口９と接続パイプ７とを連結し、集塵通路を形成している。 The upper frame 1 side of the suction device, assembled vertical rotation shaft 11 of the main joint 5, the main joint portion 5 is rotated from a substantially horizontal to a substantially vertical direction. A sub-joint portion 6 holding a connection pipe 7 is assembled to the left and right pivot shaft 12 of the main joint portion 5 and is configured to rotate approximately 180 degrees in the left-right direction. Reference numeral 8 denotes a joint pipe made of a flexible material such as rubber, which passes through the inside of the main joint portion 5 and the subjoint portion 6 and connects the suction port 9 and the connection pipe 7 to form a dust collection passage.

主継手部５に上下回動と左右回動が直交した２つの関節を備え、上下回動軸１１の中間点１３と左右回動軸１２の中間点１４を結ぶ中心線１５が一直線上で常に一定長さであり、かつ吸込具が直進時には前記中心線１５の方向と接続パイプ７の取付方向が同方向になるため、吸込具操作方向の力が主継手部５の上下回動軸１１と左右回動軸１２に操作通りに配分されて作用し、吸込具の操作追従性と直進安定性に優れ、使い勝手が良く掃除作業の向上を図ることができる。 The main joint 5 is provided with two joints in which the vertical rotation and the horizontal rotation are orthogonal to each other, and the center line 15 connecting the intermediate point 13 of the vertical rotation shaft 11 and the intermediate point 14 of the horizontal rotation shaft 12 is always in a straight line. When the suction tool is straight, the direction of the center line 15 and the attachment direction of the connection pipe 7 are the same direction when the suction tool goes straight, so that the force in the suction tool operating direction is It distributes and acts on the left and right rotation shafts 12 according to the operation, is excellent in operation followability and straight running stability of the suction tool, is easy to use, and can improve the cleaning work.

Next, a third embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

前記集塵室３内の塵埃を含んだ大気を吸引する前記吸引口９は、集塵室の斜め後方で掃除面に対し傾斜１６する様に配置させた。 The suction port 9 for sucking the air containing dust in the dust collection chamber 3 is disposed so as to be inclined 16 with respect to the cleaning surface obliquely behind the dust collection chamber.

前記吸引口９と前記接続パイプ７とを連結するゴム等の柔軟材料からなる継手管８が、掃除面に対し水平方向から垂直方向まで上下に屈曲する中間位置１７で一直線に配置されるため、吸込具の操作時において継手管８を上下に曲げ易く操作が軽くなると共に、継手管８に与える伸び縮みの負担が少なく耐久性が向上する。 Since the joint pipe 8 made of a flexible material such as rubber that connects the suction port 9 and the connection pipe 7 is arranged in a straight line at an intermediate position 17 that is bent vertically from the horizontal direction to the vertical direction with respect to the cleaning surface, When the suction tool is operated, the joint pipe 8 can be easily bent up and down, and the operation is lightened. Further, there is little burden of stretching on the joint pipe 8, and durability is improved.

Next, a fifth embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

主継手部５の上下回動軸１１に嵌合し回動する吸込具本体の上方向での最大回動位置において前記主継手部５と前記吸込具本体との間に空間部２０を設けた。 A space portion 20 is provided between the main joint portion 5 and the suction tool main body at the maximum rotation position in the upward direction of the suction tool main body that is fitted to the vertical rotation shaft 11 of the main joint portion 5 and rotates. .

次に本発明の第６の実施例を図６、図７において説明する。なお上記第一の実施例と同一構成部品については同一符号を付して、その説明を省略する。 (Example 6)
Next, a sixth embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

吸込具の従継手部６と接続パイプ７の構成において左右回動軸１２に垂直な方向に対し５度下方に角度２１を設けた。 In the configuration of the secondary joint portion 6 and the connection pipe 7 of the suction tool, an angle 21 is provided 5 degrees below the direction perpendicular to the left and right rotation shaft 12.

吸込具操作時の力のベクトル方向成分の内の吸込具を床面に押しつける下向きの力２２が作用し、吸込具を床面に安定して接地させ、掃除時の吸込具の左右ふらつきや回転等が減少し、使い勝手を良くすることができる。 The downward force 22 that presses the suction tool against the floor surface of the vector direction component of the force during operation of the suction tool acts, and the suction tool is stably grounded to the floor surface. Etc. can be reduced and usability can be improved.

またこの角度が小さ過ぎると、吸込具を床面に押しつける下向きの力２２が十分に得られず、吸込具の左右ふらつきや回転等を減少させる効果が薄れてしまう。 Moreover, if this angle is too small, the downward force 22 that presses the suction tool against the floor surface cannot be obtained sufficiently, and the effect of reducing the left-right wobbling or rotation of the suction tool will be diminished.

また逆にこの角度が５度より大きくなって行くと、吸込具を前に進ませる力より下に押しつける力の方が大きくなり、吸込具の操作力が重くなり操作性が悪くなる。 On the other hand, when this angle becomes larger than 5 degrees, the force for pressing the suction tool downward becomes larger than the force for moving the suction tool forward, and the operation force of the suction tool becomes heavy, resulting in poor operability.
