Description

本発明は、電気掃除機用ノズルに関するものである。   The present invention relates to a nozzle for a vacuum cleaner.

従来、この種の電気掃除機用ノズルとしては、本体ケース(本願発明のノズル本体に該当する)の前後にそれぞれ左右一対の車輪を設け、これらの車輪の向きが自由に変えられるようにした電気掃除機用吸込口体が知られている(例えば、特許文献1参照。)。また、ノズル本体の前後方向中央部に、左右一対の球状キャスターが設けられた電気掃除機用吸塵ノズルも知られている(例えば、特許文献2参照。)。このような車輪又は球状キャスターを用いることで、電気掃除機用のノズルを前後左右の自由な方向に移動させることができる。   Conventionally, as this type of nozzle for a vacuum cleaner, a pair of left and right wheels are provided before and after a body case (corresponding to the nozzle body of the present invention), and the direction of these wheels can be freely changed. A suction port for a vacuum cleaner is known (see, for example, Patent Document 1). There is also known a dust suction nozzle for a vacuum cleaner in which a pair of left and right spherical casters is provided at the center in the front-rear direction of the nozzle body (see, for example, Patent Document 2). By using such a wheel or a spherical caster, the nozzle for a vacuum cleaner can be moved in the front, rear, left and right directions.

特許第3457909号公報Japanese Patent No. 3457909 特開平3−195526号公報Japanese Patent Laid-Open No. 3-195526

しかしながら、引用文献1のような電気掃除機用ノズルでは、車輪が向きを変えるためにある程度の移動距離が必要になるため、急に向きを変えようとすると大回りになってしまうという問題があった。また、車輪ごとに、車輪の向きを変えるための機構が必要になるため、コストアップを招くという問題もあった。これらの車輪を引用文献2のような球状キャスターにすれば、急に向きを変える際に大回りしてしまうという問題は解決できるものの、長期間スムーズに動かすことができる球状キャスターは高価になってしまうので、コストアップを招くという問題は解決しない。引用文献2では、球状キャスターの数が二つであり、コストアップは抑えられるものの、この構成では、ノズルを移動させた際に前側又は後側が持ち上がってしまい、塵埃の吸引を良好に行えないという別の問題が生じた。   However, in the vacuum cleaner nozzle as in the cited document 1, since a certain distance of movement is necessary for the wheel to change its direction, there is a problem that if the direction is suddenly changed, it becomes a large turn. . Moreover, since a mechanism for changing the direction of the wheel is required for each wheel, there is a problem in that the cost is increased. If these wheels are made into the spherical casters as in the cited document 2, the problem of sudden rotation when suddenly changing the direction can be solved, but the spherical casters that can be moved smoothly for a long period of time become expensive. Therefore, it does not solve the problem of increasing the cost. In Cited Document 2, although the number of spherical casters is two and the increase in cost can be suppressed, in this configuration, when the nozzle is moved, the front side or the rear side is lifted, and dust suction cannot be performed satisfactorily. Another problem occurred.

本発明は以上の問題点を解決し、安価な構成で床面の自由な方向に移動させることができる電気掃除機用ノズルを提供することを目的とする。   An object of the present invention is to solve the above problems and to provide a nozzle for a vacuum cleaner that can be moved in a free direction on a floor surface with an inexpensive configuration.

The body 4 is formed in a substantially cylindrical shape. A suction port 4 </ b> B is provided at the lower portion of the body portion 4. The grip portion 5 is formed in a substantially cylindrical shape. Further, the grip portion 5 is provided at a predetermined interval from the upper end portion 4 </ b> A of the trunk portion 4. The grip portion 5 is provided in parallel with the upper end portion 4 </ b> A of the trunk portion 4. The upper end portion 4 </ b> A of the trunk portion 4 and the grip portion 5 are connected by the first connection portion 6 and the second connection portion 7.

An operation unit 8 and a display unit 9 are provided at the front of the grip unit 5. The operation unit 8 is a push button type switch. The display unit 9 is provided in front of the first connection unit 6 in the grip unit 5. The display unit 9 is provided with an LED (not shown) inside, and is provided in an annular shape over the entire circumference of the cylindrical side surface of the gripping unit 5. For this reason, the light emitted from the display unit 9 can be viewed from a wide range around the main body 2.

前記吸込口4Bには、前記アタッチメント90が着脱可能に取り付けられる。このアタッチメント90は、延長管91と電気掃除機用ノズルとしての着脱ノズル92を有して構成される。なお、前記着脱ノズル92は、図5及び図6に示すように、前記延長管91を介して前記吸込口4Bに接続されるが、前記吸込口4Bに直接接続しても良い。   The attachment 90 is detachably attached to the suction port 4B. The attachment 90 includes an extension pipe 91 and a detachable nozzle 92 as a vacuum cleaner nozzle. 5 and 6, the detachable nozzle 92 is connected to the suction port 4B via the extension pipe 91, but may be directly connected to the suction port 4B.

前記着脱ノズル92について詳述する。この着脱ノズル92は、ノズル本体93と関節部94と接続筒部95とを有する。前記ノズル本体93は、左右方向が長手方向であり、前後方向が短手方向である。そして、このノズル本体93の下部前側には、左右方向に長く形成された吸込開口96が設けられる。また、前記ノズル本体93の後部中央には、後方及び上方が開放した切欠部97が形成される。そして、この切欠部97に、前記関節部94が揺動可能に取り付けられる。また、前記切欠部97の周囲には、後方に突出する突出部98が形成される。そして、この突出部98における前記切欠部97の左右には、それぞれボールキャスター99が下方に露出して設けられる。このボールキャスター99は、被清掃面である床面Sに接する。また、前記ノズル本体93の前部の左右両端近傍には、一対の滑動部100が設けられる。この滑動部100は、起毛布により構成され、被清掃面である床面Sに接する。なお、前記ボールキャスター99は、スムーズに動かすことができるように、内部にベアリング構造が設けられる。このため、ボールキャスター99自体は、比較的大型で且つ高価な部品である。従って、前記ボールキャスター99を前記ノズル本体93の後部だけでなく前部にも設けると、前記着脱ノズル92が大型化するばかりでなく高価になる。前記吸込開口96内に回転ブラシが設けられる構造であれば、この影響はより大きくなる。一方、後述するように、起伏部102の第一回動軸AXが、前記ボールキャスター99と滑動部100の間で且つ後方寄りであることから、前記ノズル本体93の前側に加わる荷重は、後側に加わる荷重に比べて小さい。このため、前記ノズル本体93の前側には、起毛布からなる前記滑動部材100を設けるのが最適である。この滑動部材100は、前記ボールキャスター99に比べて安価で且つ取り付けのためのスペースが少なくて済むので、前記着脱ノズル92を安価に且つ小型にすることができる。また、前記ノズル本体93の後部に加わる荷重は大きいので、この部分に起毛布からなる滑動部材100を設けると、短期間で摩耗する。従って、前記ノズル本体93の前側に滑動部材100、後側にボールキャスター99を設ける構造が最適解である。更に、前記吸込開口96の後方には、左右方向に長く形成されたブラシ101が設けられる。   The detachable nozzle 92 will be described in detail. The detachable nozzle 92 has a nozzle main body 93, a joint portion 94, and a connecting cylinder portion 95. The nozzle body 93 has a longitudinal direction in the left-right direction and a short direction in the front-rear direction. A suction opening 96 that is long in the left-right direction is provided on the lower front side of the nozzle body 93. In addition, a notch 97 is formed in the rear center of the nozzle body 93, with the rear and upper sides being open. The joint portion 94 is swingably attached to the cutout portion 97. A projecting portion 98 that protrudes rearward is formed around the notch 97. Ball casters 99 are provided on the left and right sides of the notch 97 in the protruding portion 98 so as to be exposed downward. The ball caster 99 is in contact with the floor surface S that is the surface to be cleaned. A pair of sliding portions 100 are provided in the vicinity of the left and right ends of the front portion of the nozzle body 93. This sliding part 100 is comprised with the raising cloth, and touches the floor surface S which is a to-be-cleaned surface. The ball caster 99 is provided with a bearing structure so that it can be moved smoothly. For this reason, the ball caster 99 itself is a relatively large and expensive part. Accordingly, when the ball caster 99 is provided not only at the rear part but also at the front part of the nozzle body 93, the detachable nozzle 92 is not only enlarged but also expensive. If the rotary brush is provided in the suction opening 96, this influence is further increased. On the other hand, as will be described later, since the first rotation axis AX of the undulating portion 102 is between the ball caster 99 and the sliding portion 100 and closer to the rear, the load applied to the front side of the nozzle body 93 is Small compared to the load applied to the side. For this reason, it is optimal to provide the sliding member 100 made of a raised cloth on the front side of the nozzle body 93. Since the sliding member 100 is less expensive than the ball caster 99 and requires less space for attachment, the detachable nozzle 92 can be made cheaper and smaller. Moreover, since the load applied to the rear part of the nozzle body 93 is large, if the sliding member 100 made of a raised cloth is provided in this part, it is worn out in a short period of time. Therefore, the structure in which the sliding member 100 is provided on the front side of the nozzle body 93 and the ball caster 99 is provided on the rear side is the optimal solution. Further, a brush 101 that is long in the left-right direction is provided behind the suction opening 96.

前記関節部94は、起伏部102と回動部103とを有する。前記起伏部102は、揺動筒部104と、連結管105と、接続部106とを有する。一方、前記回動部103は、接続部107と前記接続筒部95とを有する。前記揺動筒部104は、その第一回動軸AXが左右方向となるように、前記切欠部97において揺動可能に支持される。なお、前記第一回動軸AXは、前記ボールキャスター99の接地点99Aよりも前で、且つ前記ボールキャスター99と滑動部100の中間位置よりも後方に位置する。換言すれば、前記第一回動軸AXは、前記ボールキャスター99と滑動部100の間で、且つ後方寄りに位置する。また、前記連結管105は、前記第一回動軸AXと交差する方向に延びて、前記連結管105と一体に形成される。更に、前記接続部106には、前記回動部103の接続部107が第二回動軸AZ周りに回動可能に接続される。なお、前記回動部103の接続部107は、図3(b)のように前記関節部94が直立した状態において、前記起伏部102の接続部106の前方に位置する。このように、前記回動部103の接続部107が前記起伏部102の接続部106の前方に位置するので、前記接続筒部95及びこれに接続された前記延長管91や本体2を前記接続筒部95の中心軸AY回りに捻ることで、前記ノズル本体93の向きを変えることができる。また、前記関節部94が直立した状態において、前記回動部103の接続部107が前記ノズル本体93の前後方向ほぼ中央に位置する。そして、前記第二回動軸AZは、前記第一回動軸AXと直交する。また、前記第二回動軸AZは、前記中心軸AY方向と直交する。但し、前記回動部103が第二回動軸AZ周りに回動するので、前記第一回動軸AXと前記中心軸AYが直交するとは限らない。従って、前記起伏部102は、ノズル本体93に対し、前記第一回動軸AX周りに回動可能に接続される。そして、前記回動部103は、前記起伏部102に対し、前記第二回動軸AZ周りに回動可能に接続される。即ち、前記回動部103は、前記ノズル本体93に対し左右方向に傾斜可能に構成される   The joint portion 94 includes an undulating portion 102 and a rotating portion 103. The undulating portion 102 includes a swinging cylinder portion 104, a connecting pipe 105, and a connecting portion 106. On the other hand, the rotating part 103 includes a connecting part 107 and the connecting cylinder part 95. The swinging cylinder portion 104 is supported by the notch 97 so as to be swingable so that the first rotation axis AX is in the left-right direction. The first rotation axis AX is positioned before the ground contact point 99A of the ball caster 99 and behind the intermediate position between the ball caster 99 and the sliding portion 100. In other words, the first rotation axis AX is located between the ball caster 99 and the sliding portion 100 and closer to the rear. The connection pipe 105 extends in a direction intersecting the first rotation axis AX and is formed integrally with the connection pipe 105. Further, the connecting portion 106 is connected to the connecting portion 107 of the rotating portion 103 so as to be rotatable around the second rotating axis AZ. The connecting portion 107 of the rotating portion 103 is positioned in front of the connecting portion 106 of the undulating portion 102 in a state where the joint portion 94 is upright as shown in FIG. Thus, since the connecting portion 107 of the rotating portion 103 is located in front of the connecting portion 106 of the undulating portion 102, the connecting tube portion 95 and the extension pipe 91 and the main body 2 connected thereto are connected to the connecting portion 107. The direction of the nozzle body 93 can be changed by twisting around the central axis AY of the cylindrical portion 95. In addition, in a state where the joint portion 94 stands upright, the connection portion 107 of the rotating portion 103 is positioned at the substantially center of the nozzle body 93 in the front-rear direction. The second rotation axis AZ is orthogonal to the first rotation axis AX. The second rotation axis AZ is orthogonal to the central axis AY direction. However, since the rotation unit 103 rotates around the second rotation axis AZ, the first rotation axis AX and the central axis AY are not always orthogonal. Therefore, the undulating portion 102 is connected to the nozzle body 93 so as to be rotatable around the first rotation axis AX. The rotating portion 103 is connected to the undulating portion 102 so as to be rotatable around the second rotation axis AZ. That is, the rotating part 103 is configured to be tiltable in the left-right direction with respect to the nozzle body 93.

なお、前記関節部94は、図3(a)に示すように、後方に水平な状態まで倒すことができる。一方、前記関節部94は、図3(b)に示す直立した状態よりも前方に10度傾斜可能である。そして、このように前記関節部94が直立状態から前方に10度傾斜した状態において、前記回動部103の接続部107は、前記ノズル本体93の上方に位置する。より詳細には、前記接続部107は、前記ボールキャスター99の接地点99Aと前記滑動部100との間に位置する。   As shown in FIG. 3A, the joint portion 94 can be tilted back to a horizontal state. On the other hand, the joint portion 94 can be tilted forward by 10 degrees from the upright state shown in FIG. In this way, in the state where the joint portion 94 is inclined 10 degrees forward from the upright state, the connecting portion 107 of the rotating portion 103 is located above the nozzle body 93. More specifically, the connecting portion 107 is located between the ground contact point 99A of the ball caster 99 and the sliding portion 100.

次に、本実施形態の作用について説明する。なお、図5及び図6において示されていないが、使用者が前記把持部5を右手で把持しているものとする。被清掃面である床面S上を掃除する場合、使用者は、図5に示されるような、前記第一連結部6と第二連結部7とが前後に配列される姿勢で、前記把持部5を把持する。この姿勢では、前記着脱ノズル92のノズル本体93の長手方向は左右方向となる。なお、前記本体2と延長管91と関節部94の床面Sに対する角度は、図5の場合60度であるが、使用者の体型、使用者と前記電気掃除機1との位置関係、動かし方の癖等により変化し得る。従って、今後の説明において姿勢について述べる際、床面Sとの角度の違いは無視する。この姿勢のまま使用者が前記操作部8を押すと、前記本体2の胴部4内に設けられた図示しない電動送風機が作動して、吸引気流を発生させる。この吸引気流は、前記吸込開口96から吸引され、前記ノズル本体93、関節部94、接続筒部95、延長管91を経て前記吸込口4Bから胴部4内に流入する。この際、前記胴部4内に設けられた図示しないフィルタバッグにおいて、吸引気流中の塵埃が分離される。なお、塵埃を分離する機構は、サイクロン分離装置等であっても良い。更に、前記吸引気流は、前記電動送風機から図示しない排気口を経て前記胴部4外に排出される。また、前記操作部8を押すことで、前記表示部9から光が放出される。   Next, the operation of this embodiment will be described. Although not shown in FIGS. 5 and 6, it is assumed that the user is holding the grip portion 5 with the right hand. When cleaning the floor surface S, which is the surface to be cleaned, the user holds the grip in a posture in which the first connecting portion 6 and the second connecting portion 7 are arranged in the front-rear direction as shown in FIG. Grip part 5. In this posture, the longitudinal direction of the nozzle body 93 of the detachable nozzle 92 is the left-right direction. In addition, the angle with respect to the floor surface S of the said main body 2, the extension pipe | tube 91, and the joint part 94 is 60 degree | times in the case of FIG. 5, but a user's body shape, the positional relationship between a user and the said vacuum cleaner 1, and movement. It may change depending on the direction of the direction. Therefore, the difference in angle with the floor surface S is ignored when describing the posture in the future description. When the user presses the operation unit 8 in this posture, an electric blower (not shown) provided in the body 4 of the main body 2 is activated to generate a suction airflow. The suction airflow is sucked from the suction opening 96 and flows into the trunk portion 4 from the suction port 4B through the nozzle body 93, the joint portion 94, the connecting tube portion 95, and the extension tube 91. At this time, dust in the suction airflow is separated in a filter bag (not shown) provided in the body 4. The mechanism for separating dust may be a cyclone separation device or the like. Further, the suction airflow is discharged out of the body portion 4 from the electric blower through an exhaust port (not shown). Further, when the operation unit 8 is pressed, light is emitted from the display unit 9.

この姿勢のまま、使用者が、前記床面Sに沿って、図5に両矢印Dで示される前後方向に電気掃除機1を移動させることで、床面S上の塵埃が吸引される。なお、前記着脱ノズル92は、両矢印Dで示される前後方向にのみ動かされる訳ではなく、左右方向にも動かすことができる。即ち、前記着脱ノズル92を左右方向にずらしたり、左右方向に曲げたりすることができる。この際、前記ボールキャスター99が床面S上のあらゆる方向に転がることが可能であり、前記滑動部材100も床面S上のあらゆる方向に滑らすことが可能である。従って、前記着脱ノズル92は、床面S上のあらゆる方向に自由に動かすことができる。また、前記ボールキャスター99も滑動部材100も、瞬時に移動方向を変えることができるので、前記着脱ノズル92を動かす際に小回りがきく。なお、前述した通り、前記関節部94の第一回動軸AXが前記ボールキャスター99の接地点99Aよりも前に位置する。より詳細には、前記第一回動軸AXは、前記接地点99Aと前記滑動部100との間に位置する。このため、前記着脱ノズル92を前方に動かした際に、前記ノズル本体93の前側が浮き上がることがない。従って、前記吸込開口96と床面Sとの距離が適正に保たれる。   With this posture, the user moves the vacuum cleaner 1 along the floor surface S in the front-rear direction indicated by the double-headed arrow D in FIG. The detachable nozzle 92 is not only moved in the front-rear direction indicated by the double arrow D, but can also be moved in the left-right direction. That is, the detachable nozzle 92 can be shifted in the left-right direction or bent in the left-right direction. At this time, the ball caster 99 can roll in any direction on the floor surface S, and the sliding member 100 can also slide in any direction on the floor surface S. Therefore, the detachable nozzle 92 can be freely moved in any direction on the floor surface S. Further, since the moving direction of both the ball caster 99 and the sliding member 100 can be instantaneously changed, a small turn is made when the detachable nozzle 92 is moved. As described above, the first rotation axis AX of the joint portion 94 is positioned before the ground contact point 99A of the ball caster 99. More specifically, the first rotation axis AX is located between the ground contact point 99A and the sliding part 100. For this reason, when the detachable nozzle 92 is moved forward, the front side of the nozzle body 93 does not rise. Therefore, the distance between the suction opening 96 and the floor surface S is maintained appropriately.

図5の姿勢から、使用者が、前記把持部5を使用者から見て左回り(正面視で右回り)に90度捻ると、図6の姿勢となる。この姿勢では、前記第一連結部6が使用者から見て左側(正面視で右側)となり、第二連結部7が使用者から見て右側(正面視で左側)となる。そして、この姿勢では、前記着脱ノズル92のノズル本体93の長手方向は、前後方向となる。この場合、前記ノズル本体93の使用者から見た右側が前、左側が後となる(正面視では、前記ノズル本体93の左側が前、右側が後となる)。なお、使用者が前記把持部5を左手で把持し、この把持部5を使用者から見て右回りに回動させた場合、図6とは逆に、前記ノズル本体93の使用者から見た右側が後、左側が前となる(正面視では、前記ノズル本体93の右側が前、左側が後となる)。この姿勢では、前記ノズル本体93は、このノズル本体93の前端から前記突出部98の後端までの距離よりも広い隙間であれば、挿入することができる。なお、前記把持部5の捻り角度と前記ノズル本体93の水平方向の回動角度は一致する。即ち、前記把持部5を使用者から見て左回りに45度捻ると、前記ノズル本体93は左回りに45度回動する。   When the user twists the grip portion 5 counterclockwise by 90 degrees when viewed from the user (clockwise in front view), the posture shown in FIG. 6 is obtained. In this posture, the first connecting portion 6 is on the left side (right side when viewed from the front) and the second connecting portion 7 is on the right side (left side when viewed from the front) when viewed from the user. In this posture, the longitudinal direction of the nozzle body 93 of the detachable nozzle 92 is the front-rear direction. In this case, the right side viewed from the user of the nozzle body 93 is the front and the left side is the rear (in front view, the left side of the nozzle body 93 is the front and the right side is the rear). Note that when the user grips the grip portion 5 with his left hand and rotates the grip portion 5 clockwise as viewed from the user, the user sees the nozzle main body 93 as opposed to FIG. The right side is rear and the left side is front (in front view, the right side of the nozzle body 93 is front and the left side is rear). In this posture, the nozzle body 93 can be inserted if it is a gap wider than the distance from the front end of the nozzle body 93 to the rear end of the protrusion 98. Note that the twist angle of the grip portion 5 and the horizontal rotation angle of the nozzle body 93 coincide with each other. That is, when the grip portion 5 is twisted 45 degrees counterclockwise as viewed from the user, the nozzle body 93 rotates 45 degrees counterclockwise.

この姿勢のまま、使用者が、前記床面Sに沿って、図6に両矢印Dで示される前後方向に電気掃除機1を移動させることで、床面S上の塵埃が吸引される。なお、前記ノズル本体93を基準にすると、図5の姿勢に比べて90度異なった方向に移動することになる。しかしながら、前述したように、前記ノズル本体93に前記ボールキャスター99と滑動部材100が設けられるので、殆ど抵抗なく図6の両矢印Dの方向に前記着脱ノズル92を動かすことができる。なお、前記着脱ノズル92は、両矢印Dで示される前後方向にのみ動かされる訳ではなく、左右方向にも動かすことができる。即ち、前記着脱ノズル92を左右方向にずらしたり、左右方向に曲げたりすることができる。この際、前記ボールキャスター99が床面S上のあらゆる方向に転がることが可能であり、前記滑動部材100も床面S上のあらゆる方向に滑らすことが可能であることから、前記着脱ノズル92は床面S上のあらゆる方向に自由に動かすことができる。また、前記ボールキャスター99も滑動部材100も、瞬時に移動方向を変えることができるので、前記着脱ノズル92を動かす際に小回りがきく。なお、図6の姿勢における前記着脱ノズル92では、図4(b)に示すように、前記関節部94の回動部103の接続部107が、前記ノズル本体93のほぼ中央上方に位置する。このため、前記着脱ノズル92を両矢印Dの方向に移動させる際に、前記ノズル本体93の吸込開口96側も突出部98側も床面Sから浮き上がることなく、良好に移動させることができる。   With this posture, the user moves the vacuum cleaner 1 in the front-rear direction indicated by the double arrow D in FIG. 6 along the floor surface S, whereby the dust on the floor surface S is sucked. When the nozzle body 93 is used as a reference, the nozzle body 93 moves in a direction different by 90 degrees compared to the posture shown in FIG. However, as described above, since the ball caster 99 and the sliding member 100 are provided in the nozzle body 93, the detachable nozzle 92 can be moved in the direction of the double arrow D in FIG. The detachable nozzle 92 is not only moved in the front-rear direction indicated by the double arrow D, but can also be moved in the left-right direction. That is, the detachable nozzle 92 can be shifted in the left-right direction or bent in the left-right direction. At this time, the ball caster 99 can roll in any direction on the floor surface S, and the sliding member 100 can also slide in any direction on the floor surface S. It can be freely moved in any direction on the floor surface S. Further, since the moving direction of both the ball caster 99 and the sliding member 100 can be instantaneously changed, a small turn is made when the detachable nozzle 92 is moved. In the attachable / detachable nozzle 92 in the posture shown in FIG. 6, as shown in FIG. 4B, the connecting portion 107 of the rotating portion 103 of the joint portion 94 is positioned substantially above the center of the nozzle body 93. For this reason, when the detachable nozzle 92 is moved in the direction of the double-headed arrow D, the suction opening 96 side and the protruding portion 98 side of the nozzle body 93 can be moved well without being lifted from the floor surface S.

なお、使用者の癖によっては、図5の姿勢から90度より大きく捻ったり、90度より小さく捻ったりする場合もある。また、使用者の癖によっては、図6の姿勢から前記電気掃除機1を両矢印Dの方向に移動させる際に、意図せず前記中心軸AY回りに回動してしまう可能性もある。しかしながら、前述したように、前記関節部94は、前記突出部98側(後方)に水平な状態から前記吸込開口96側(前方)に10度傾斜した状態までの間で回動可能である。このため、使用者が図5の姿勢から前記把持部5を100度捻ったとしても、前記関節部94が垂直から前記吸込開口96側に10度傾斜できるので、許容される。また、使用者が図5の姿勢から前記把持部5を80度捻ったとしても、前記関節部94が垂直から前記突出部98側に10度傾斜した状態となる。従って、前記把持部5の捻り量90度に対し多少の誤差があったとしても、許容される。   Depending on the user's heel, the user may twist more than 90 degrees or less than 90 degrees from the posture shown in FIG. Further, depending on the user's heel, when the electric vacuum cleaner 1 is moved in the direction of the double arrow D from the posture shown in FIG. 6, there is a possibility that the user unintentionally rotates around the central axis AY. However, as described above, the joint portion 94 is rotatable from a state horizontal to the protruding portion 98 side (rear) to a state inclined 10 degrees toward the suction opening 96 side (front). For this reason, even if the user twists the grip part 5 from the posture of FIG. 5 by 100 degrees, the joint part 94 can be inclined from the vertical to the suction opening 96 side by 10 degrees. Further, even if the user twists the grip part 5 by 80 degrees from the posture of FIG. 5, the joint part 94 is inclined 10 degrees from the vertical to the projecting part 98 side. Therefore, even if there is a slight error with respect to the twist amount 90 degrees of the grip portion 5, it is allowed.

なお、使用者が図5の姿勢から100度を超えて前記把持部5を捻った場合は、前記突出部98側が前記床面Sから浮くことになる。しかしながら、図5の姿勢から前記把持部5を捻る角度が90度でない場合、前記ノズル本体93の長手方向と両矢印Dの方向は平行とならず、90度との差に応じた角度をなす。従って、前記把持部5の捻り角度が大きかったり小さかったりすることを、前記着脱ノズル92を見ることで知ることができる。このため、使用者は、前記ノズル本体93の長手方向と両矢印Dの方向がほぼ平行となるように、前記把持部5の捻り角度を調整することができる。その上で、前記着脱ノズル92を両矢印Dの方向に移動させた際に前記中心軸AY回りの回動運動が生じたとしても、前記関節部94の揺動範囲内であれば許容される。なお、前記接続筒部95が前記中心軸AY周りに回動すると、前記ノズル本体93が水平方向に揺動することになる。しかしながら、前記ノズル本体93に前記ボールキャスター99と滑動部材100が設けられるので、揺動しながらでも前記着脱ノズル92を両矢印Dの方向にスムーズに移動させることができる。   In addition, when the user twists the grip portion 5 beyond 100 degrees from the posture of FIG. 5, the protruding portion 98 side floats from the floor surface S. However, when the angle of twisting the gripping part 5 from the posture of FIG. 5 is not 90 degrees, the longitudinal direction of the nozzle body 93 and the direction of the double-headed arrow D are not parallel, and form an angle corresponding to the difference from 90 degrees. . Therefore, it can be known by looking at the detachable nozzle 92 that the twisting angle of the grip portion 5 is large or small. Therefore, the user can adjust the twist angle of the grip portion 5 so that the longitudinal direction of the nozzle body 93 and the direction of the double-headed arrow D are substantially parallel. In addition, even if a rotational movement about the central axis AY occurs when the detachable nozzle 92 is moved in the direction of the double arrow D, it is allowed as long as it is within the swing range of the joint portion 94. . In addition, when the connection cylinder part 95 rotates around the center axis AY, the nozzle body 93 swings in the horizontal direction. However, since the ball caster 99 and the sliding member 100 are provided in the nozzle main body 93, the detachable nozzle 92 can be smoothly moved in the direction of the double arrow D while swinging.

なお、前記関節部94が垂直に対し前方に10度傾いた状態のまま、両矢印Dの方向に移動させることができる。この場合でも、前述した通り、前記回動部103の接続部107は、前記ノズル本体93の上方、より詳細には、前記ボールキャスター99の接地点99Aと前記滑動部100との間に位置する。このため、前記着脱ノズル92を両矢印Dの方向に移動させる際に、前記ノズル本体93の吸込開口96側も突出部98側も床面Sから浮き上がることなく、良好に移動させることができる。   Note that the joint portion 94 can be moved in the direction of the double-headed arrow D while being tilted 10 degrees forward with respect to the vertical. Even in this case, as described above, the connecting portion 107 of the rotating portion 103 is located above the nozzle body 93, more specifically, between the ground contact point 99A of the ball caster 99 and the sliding portion 100. . For this reason, when the detachable nozzle 92 is moved in the direction of the double-headed arrow D, the suction opening 96 side and the protruding portion 98 side of the nozzle body 93 can be moved well without being lifted from the floor surface S.

以上のように本発明の電気掃除機用ノズルである着脱ノズル92は、長手方向と短手方向を有するノズル本体93と、前記長手方向に形成された第一回動軸AX回りに回動可能な関節部94と、この関節部94の端部に形成された接続筒部95とを有し、前記ノズル本体93の短手方向の一方側である後側に、被清掃面である床面Sに接するボールキャスター99が設けられ、前記ノズル本体93の短手方向の他方側である前側に、床面Sに接する滑動部100が設けられると共に、前記第一回動軸AXが、短手方向における前記ボールキャスター99と滑動部100との間で且つ前記ボールキャスター99寄りに設けられることにより、安価な構成で、前記ノズル本体93の前部又は後部が浮くことなく、前記ノズル本体93を水平方向に自由に移動させることができるものである。   As described above, the detachable nozzle 92 that is the nozzle for the vacuum cleaner of the present invention can be rotated around the nozzle body 93 having the longitudinal direction and the lateral direction and the first rotation axis AX formed in the longitudinal direction. A floor surface which is a surface to be cleaned on the rear side which is one side of the nozzle body 93 in the short direction of the nozzle body 93. A ball caster 99 in contact with S is provided, and a sliding portion 100 in contact with the floor surface S is provided on the front side which is the other side of the nozzle body 93 in the short direction, and the first rotation axis AX is short. The nozzle body 93 is provided between the ball caster 99 and the sliding part 100 in the direction and close to the ball caster 99, so that the nozzle body 93 can be moved at a low cost without causing the front or rear part of the nozzle body 93 to float. Horizontally In which it can be moved to the grounds.

また、本発明の着脱ノズル92は、前記関節部94が、前記第一回動軸AX回りに回動可能な起伏部102と、前記第一回動軸AX及び前記接続筒部95の中心軸AYと交差する第二回動軸AZ回りに回動可能な回動部103とを有し、

前記回動部103が前記長手方向である左右方向に傾斜可能に構成されることで、前記接続筒部95を前記中心軸AY周りに回動させる動きで前記ノズル本体93の向きを変えることができるものである。
Further, the detachable nozzle 92 according to the present invention includes the undulating portion 102 in which the joint portion 94 can rotate around the first rotation axis AX, the first rotation axis AX, and the central axis of the connection cylinder portion 95. A rotation unit 103 that can rotate around a second rotation axis AZ that intersects AY,

The rotation of the nozzle main body 93 can be changed by the rotation of the connecting cylinder 95 around the central axis AY by configuring the rotation 103 to be tiltable in the left-right direction, which is the longitudinal direction. It can be done.

また、本発明の着脱ノズル92は、前記起伏部102が、前側に10度傾斜可能に構成されることで、使用者の癖で前記接続筒部95を中心軸AY回りに回動させ過ぎたとしても、前記ノズル本体93のボールキャスター99側が浮くことがなく、良好に塵埃を吸引することができるものである。   Further, the detachable nozzle 92 of the present invention has the undulating portion 102 configured to be tiltable by 10 degrees toward the front side, so that the connecting cylinder portion 95 is rotated too much around the central axis AY by the user's heel. However, the ball caster 99 side of the nozzle body 93 does not float, and dust can be sucked in favorably.

更に、本発明の着脱ノズル92は、前記関節部94が直立した状態において、前記回動部103が、前記起伏部102の前側に設けられると共に、前記起伏部102を前方に最大限傾斜させた状態で、前記回動部103の接続部107が前記ノズル本体93の上方に位置することで、このノズル本体93の長手方向が前後となる姿勢で前記着脱ノズル92を動かした際に、前記ボールキャスター99側が浮くことがなく、良好に塵埃を吸引することができるものである。   Further, in the removable nozzle 92 of the present invention, in the state where the joint portion 94 is upright, the rotating portion 103 is provided on the front side of the undulating portion 102 and the undulating portion 102 is inclined forward to the maximum. In this state, when the connecting portion 107 of the rotating portion 103 is positioned above the nozzle body 93, the ball 92 is moved when the detachable nozzle 92 is moved in a posture in which the longitudinal direction of the nozzle body 93 is front and rear. The caster 99 side does not float and can suck dust well.

なお、本発明は以上の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形実施が可能である。例えば、上記実施形態では、前記ボールキャスター99を前記ノズル本体93の後部から突出する突出部98に設けたが、この突出部98を設けずに前記ノズル本体93にボールキャスター99を設けても良い。また、上記実施形態では、前記関節部94の垂直に対する前傾角度を最大10度としたが、10度以上としても良く、また、10度以下としても良い。   In addition, this invention is not limited to the above embodiment, A various deformation | transformation implementation is possible within the range of the summary of invention.
