Description

本発明は、掃除機本体にホースを接続して使用する電気掃除機に関するものである。   The present invention relates to a vacuum cleaner used by connecting a hose to a cleaner body.

従来の掃除機本体にホースを接続して使用する電気掃除機は、ホース先端に接続されたパイプを途中で屈曲させてパイプを自立させる構成としている（たとえば、特許文献１参照）。   A conventional vacuum cleaner used by connecting a hose to a main body of a vacuum cleaner has a configuration in which a pipe connected to the tip of the hose is bent in the middle to make the pipe self-supporting (for example, see Patent Document 1).

特開２００１−２６９２９４号公報（第７頁、第１１図）JP 2001-269294 A (page 7, FIG. 11)

従来の掃除機本体にホースを接続して使用する電気掃除機は、ホース先端に接続されたパイプを途中で屈曲させて自立させる構成としているが、自立させた状態においてホースのパイプからの導出方向が上方向となっているため、ホースに作用する重力やホースの屈曲状態からの復元力がパイプに加わり、安定性が悪くなるという課題があった。   A conventional vacuum cleaner that is used with a hose connected to the main body of the vacuum cleaner has a structure in which the pipe connected to the tip of the hose is bent in the middle to be self-supporting. Therefore, there is a problem that the gravity acting on the hose and the restoring force from the bent state of the hose are applied to the pipe and the stability is deteriorated.

本発明は、上述のような課題を解決するためになされたもので、容易にパイプを自立させることができるとともに、パイプが自立した状態において安定性の優れた電気掃除機を得ることを目的とするものである。   The present invention has been made to solve the above-described problems, and it is possible to easily make a pipe self-supporting and to obtain a vacuum cleaner having excellent stability in a state where the pipe is self-supporting. To do.

本発明に係る電気掃除機は、掃除機本体と、前記掃除機本体に一端が接続され他端にパイプが接続されたホースと、前記パイプに回動可能に接続された吸込口体とを備え、前記吸込口体を床面に置いた状態で前記パイプを床面に対する垂直位置を越えて前記吸込口体の前方向へ傾斜するよう回動させて該パイプを自立状態に保持できるようにした電気掃除機において、前記パイプに該パイプと連通し且つ上下方向に回動可能に連結されたホース接続部を設け、前記ホース接続部に前記ホースの一端を接続するとともに前記パイプを自立状態に保持したとき、前記ホース接続部からの前記ホースの導出方向がその自重により下向きなるよう前記ホース接続部が回動し、前記パイプと前記吸込口体を係合する係合部を設け、前記吸込口体を床面に置いた状態で前記パイプを床面に対する垂直位置を越えて前記吸込口体の前方へ傾斜した時、前記パイプと前記吸込口体の係合部が係合し前記パイプの移動を制限するものである。 The vacuum cleaner according to the present invention includes a vacuum cleaner body, a hose having one end connected to the vacuum cleaner body and a pipe connected to the other end, and a suction port body rotatably connected to the pipe. The pipe can be held in a self-supporting state by rotating the pipe so as to incline toward the front of the suction port body over a vertical position with respect to the floor surface with the suction port body placed on the floor surface. In the vacuum cleaner, the pipe is provided with a hose connection portion that communicates with the pipe and is pivotably connected in the vertical direction, and connects the one end of the hose to the hose connection portion and holds the pipe in a self-supporting state. The hose connection portion is rotated so that the direction in which the hose is led out from the hose connection portion is downward due to its own weight, and an engagement portion for engaging the pipe and the suction port body is provided, and the suction port Body on the floor When the pipe is tilted forward of the suction port body beyond the vertical position with respect to the floor surface, the engagement portion of the pipe and the suction port body is engaged to restrict the movement of the pipe. .

以上のように本発明によれば、パイプを床面に対して垂直状態よりもさらに吸込口体の前方に傾斜可能な構成とし、かつホースのパイプからの導出方向を水平方向かそれより下方に向ける構成としたので、容易にパイプを自立させることができるだけでなく、自立状態の安定性を向上させることができるという効果がある。   As described above, according to the present invention, the pipe is configured to be able to tilt further forward of the suction port body than the vertical state with respect to the floor surface, and the direction of the hose being led out from the pipe is horizontal or lower than that. Since the structure is directed, it is possible not only to easily make the pipe self-supporting, but also to improve the stability of the self-supporting state.

1 is a schematic explanatory view showing a state where a pipe of a vacuum cleaner according to Embodiment 1 of the present invention is self-supporting, and FIG. 2 is a rear perspective view showing a structure of a connecting portion between a hose and a pipe shown in FIG. 3 is a side cross-sectional view thereof, FIG. 4 is a cross-sectional plan view of the cross section AA in FIG. 3, FIG. 5 is a side cross-sectional view of the suction port body shown in FIG. In FIG. 1, 1 is a main body of the cleaner, 2 is a main body wheel for movement provided in the main body of the cleaner 1, 3 is a rotating wheel provided in the main body of the cleaner 1 and directing the course in the moving direction, and 4 is cleaning. It is an electric blower that is provided in the machine body 1 and sucks air. 5 is a bellows hose connected to the front of the vacuum cleaner main body 1, a main body connection pipe 6 is provided on the side connected to the vacuum cleaner main body 1, and a hose connection portion 8 connected to the pipe 7 is provided on the other side. ing. The main body connecting pipe 6 and the hose connecting portion 8 are attached to the hose 5 so as to be able to rotate 360 degrees in the circumferential direction. Reference numeral 9 denotes a dust collecting unit that is provided in the cleaner body 1 and captures dust sucked together with air by the electric blower 4. Reference numeral 10 denotes a handle provided on the pipe 7. The handle 10 is about 20 cm below the grip position of the handle 10. A hose 5 is rotatably connected via a hose connection portion 8. 11 is a joint provided on the rear side of the suction port body 12, to a position where the pipe 7 is inclined further forward than the position where the pipe 7 is perpendicular to the floor surface (dotted line B in FIG. 1), The pipe 7 is pivotally connected to the suction port 12. Further, the pipe 7 is provided by a joint 11 so as to be rotatable about the front-rear direction of the suction port body 12. Reference numeral 13 denotes a locking claw indicating an engaging portion provided in the vicinity of the joint 11 of the pipe 7, and reference numeral 14 denotes a locking groove indicating an engaging portion provided in the upper portion of the suction port body 12. When inclined, the locking claw 13 is locked in the locking groove 14. When the locking claw 13 is locked in the locking groove 14, the rotation of the pipe 7 is restricted. Reference numeral 15 denotes a front wheel provided in front of the lower surface of the suction port body 12, and 16 denotes a wheel support body that supports a rear wheel 17 provided behind the suction port body 12.

ホース接続部８はパイプ７に対して回動自在であるため、パイプ７の傾斜角度を変えてもホース接続部８からのホース５の導出方向は常に下向きとなる。そして、パイプ７を前傾させて自立させる際、パイプ７にはホース接続部８を介してホース５に作用する重力とホース５の湾曲状態からの復元力が加わる。このパイプ７に作用する力の大きさおよびその方向はパイプ７を前傾させて自立させる際の吸込口体１２と掃除機本体１の距離によって変わり、距離が長いほどパイプ７を後方に引く力が大きくなり、距離が短いと前方に押す力が大きくなる。したがって、パイプ７を自立させるためには、パイプ７にホース５からの力が加わった状態でパイプ７の重心が吸込口体１２の前方車輪１５と後方車輪１７間の上方に位置するように吸込口体１２と掃除機本体１間の距離を調節する必要がある。   Since the hose connection portion 8 is rotatable with respect to the pipe 7, the lead-out direction of the hose 5 from the hose connection portion 8 is always downward even when the inclination angle of the pipe 7 is changed. When the pipe 7 is tilted forward to be self-supporting, the pipe 7 is subjected to gravity acting on the hose 5 and a restoring force from the curved state of the hose 5 via the hose connection portion 8. The magnitude and direction of the force acting on the pipe 7 vary depending on the distance between the suction port body 12 and the cleaner body 1 when the pipe 7 is tilted forward to be independent, and the longer the distance is, the more the force pulls the pipe 7 backward. When the distance is short, the force to push forward increases. Therefore, in order to make the pipe 7 self-supporting, suction is performed so that the center of gravity of the pipe 7 is located above the front wheel 15 and the rear wheel 17 of the suction port body 12 with the force from the hose 5 applied to the pipe 7. It is necessary to adjust the distance between the mouth body 12 and the cleaner body 1.

なお、本実施の形態１ではパイプ７の垂直状態から吸込口体１２の前方への傾斜限界角度を約１０度に設定しており、パイプ７をこの角度まで前傾させてホース５がパイプ７に沿って垂れ下がった状態で、ホース５を含むパイプ７の重心が吸込口体１２の前方車輪１５と後方車輪１７間の上方に位置するように構成しているため、パイプ７が安定して自立する。   In the first embodiment, the inclination limit angle from the vertical state of the pipe 7 to the front of the suction port body 12 is set to about 10 degrees, and the pipe 7 is tilted forward to this angle so that the hose 5 is connected to the pipe 7. Since the center of gravity of the pipe 7 including the hose 5 is located above the front wheel 15 and the rear wheel 17 of the suction port body 12 in a state where the pipe 7 is hung along the pipe 7, the pipe 7 is stable and independent. To do.

次に図２、図３、図４を用いてホース５とパイプ７の接続部分の構造について詳細に説明する。ホース５とパイプ７の接続部分に設けられたホース接続部８は、ホース５に回動可能に接続されるホース接続管１８と、パイプ７に回動可能に設けられた湾曲面を一部開口したホース接続外筒１９と、ホース接続管１８先端に設けられた上側湾曲壁２０および下側湾曲壁２１と、ホース接続外筒１９と上側湾曲壁２０および下側湾曲壁２１との間に摺動可能に設けられた上側可動壁２２と下側可動壁２３によって構成されている。上側湾曲壁２０と上側可動壁２２および下側湾曲壁２１と下側可動壁２３はそれぞれ回動動作時に互いを係合させる突起を端部に備えている。ホース接続管１８はパイプ７とほぼ平行となる状態から約１８０度回動可能に構成されており、パイプ７と平行となる状態においては上側可動壁２２が上側湾曲壁２０の端部に引かれて下側に引き出され、また、約１８０度回転した状態においては下側可動壁２３が下側湾曲壁２１の端部に引かれて上側に引き出されることにより、パイプ７内の吸気風路が空気を洩らすことなくホース５と連通する。なお、２４はハンドル１０内に設けられた電動送風機４の運転停止および出力制御を行うコントロール部である。   Next, the structure of the connecting portion between the hose 5 and the pipe 7 will be described in detail with reference to FIGS. A hose connection portion 8 provided at a connection portion between the hose 5 and the pipe 7 is partially opened at a hose connection pipe 18 that is rotatably connected to the hose 5 and a curved surface that is rotatably provided at the pipe 7. Between the hose connection outer cylinder 19, the upper curved wall 20 and the lower curved wall 21 provided at the tip of the hose connection pipe 18, and the hose connection outer cylinder 19, the upper curved wall 20 and the lower curved wall 21. The upper movable wall 22 and the lower movable wall 23 are movably provided. The upper curved wall 20, the upper movable wall 22, and the lower curved wall 21 and the lower movable wall 23 are provided with protrusions at their end portions that engage with each other during the rotation operation. The hose connection pipe 18 is configured to be able to turn about 180 degrees from a state substantially parallel to the pipe 7, and in a state parallel to the pipe 7, the upper movable wall 22 is pulled to the end of the upper curved wall 20. In the state of being rotated about 180 degrees, the lower movable wall 23 is pulled by the end of the lower curved wall 21 and pulled upward, so that the intake air passage in the pipe 7 is It communicates with the hose 5 without leaking air. Reference numeral 24 denotes a control unit that performs operation stop and output control of the electric blower 4 provided in the handle 10.

また、ホース接続管１８にはホース５側端部の内壁にリング状の電極２５、２６が埋設され、ホース５の外周部に埋設されたケーブル２７、２８と電気的に接続された端子２９、３０と摺接している。そして、電極２５、２６とコントロール部２４とが電気的に接続されている。また、電極２５、２６にはリード線３１、３２が接続され、上側湾曲壁２０および下側湾曲壁２１の回動中心に設けられた回動中心孔３３と、回動中心孔３３が嵌合される外筒中心孔３４とホース接続外筒１９の側面部に設けられた外筒配線室３５を経由してハンドル１０内に設けられたコントロール部２４に接続される。リード線３１、３２はホース接続管１８の回動を許容するだけの十分なたるみをもって配設されているため回動により断線することはない。   Further, ring-shaped electrodes 25 and 26 are embedded in the inner wall of the hose 5 side end portion in the hose connection pipe 18, and terminals 29 electrically connected to cables 27 and 28 embedded in the outer peripheral portion of the hose 5. 30 is in sliding contact. The electrodes 25 and 26 and the control unit 24 are electrically connected. Further, lead wires 31 and 32 are connected to the electrodes 25 and 26, and a rotation center hole 33 provided at a rotation center of the upper curved wall 20 and the lower curved wall 21 and a rotation center hole 33 are fitted. The outer cylinder center hole 34 and the outer cylinder wiring chamber 35 provided in the side surface of the hose connection outer cylinder 19 are connected to the control section 24 provided in the handle 10. Since the lead wires 31 and 32 are disposed with sufficient slack to allow the hose connecting pipe 18 to rotate, the lead wires 31 and 32 are not disconnected by the rotation.

次に、図５、図６を用いて吸込口体１２とパイプ７の接続部分の構造について詳細に説明する。継手１１は吸込口体１２とパイプ７の接続部分に回動可能に設けられた継手基体３６と、パイプ７先端に設けられたパイプ先端湾曲上壁３７とパイプ先端湾曲下壁３８と、継手基体３６とパイプ先端湾曲上壁３７との間に摺動可能に設けられた継手可動湾曲壁３９とによって構成されている。継手基体３６は吸込口体１２後方に連結部材４０によって回動可能な状態で接続されており、パイプ７が左右方向に回動されても吸込口体１２からの吸気風路をパイプ７に連結する。また、パイプ７が前後方向に回動するとパイプ先端湾曲上壁３７とパイプ先端湾曲下壁３８が継手基体３６に沿って回動する。このとき、継手可動湾曲壁３９は端部に設けられた突起とパイプ先端湾曲上壁３７の端部に設けられた突起の係合により摺動するため、パイプ７が前後に回動されても吸気風路からの空気洩れや吸気風路の遮断は生じない。したがって、パイプ７を清掃面に対してほぼ水平にして使用しても吸気が可能な構成となっている。   Next, the structure of the connection portion between the suction port body 12 and the pipe 7 will be described in detail with reference to FIGS. The joint 11 includes a joint base 36 rotatably provided at a connection portion between the suction port body 12 and the pipe 7, a pipe tip curved upper wall 37, a pipe tip curved lower wall 38 provided at the pipe 7 tip, and a joint base. 36 and a joint movable curved wall 39 slidably provided between the pipe tip curved upper wall 37. The joint base 36 is connected to the rear side of the suction port body 12 so as to be rotatable by the connecting member 40, and the intake air passage from the suction port body 12 is connected to the pipe 7 even when the pipe 7 is rotated in the left-right direction. To do. When the pipe 7 is rotated in the front-rear direction, the pipe tip curved upper wall 37 and the pipe tip curved lower wall 38 are rotated along the joint base 36. At this time, the joint movable curved wall 39 slides due to the engagement between the projection provided at the end and the projection provided at the end of the pipe tip curved upper wall 37, so that even if the pipe 7 is rotated back and forth. Air leakage from the intake air passage and blockage of the intake air passage do not occur. Therefore, the air can be sucked even when the pipe 7 is used almost horizontally with respect to the cleaning surface.

パイプ７を自立させるには、パイプ７を掃除機本体１に近づけ、ホース接続部８が回動してパイプ７がホース５に接触する状態になったときに、パイプ７を傾斜限界位置まで前傾させる。これにより、ホース５がパイプ７に沿って垂れ下がり、安定性の良い自立状態となる。また、パイプ７が回動限界まで前傾すると、係止爪１３が係止溝１４に嵌合する（図５中の点線参照）。このときパイプ７は前傾して前後方向にバランスした状態にあり、継手基体３６の回動が制限され、左右方向にも傾倒しなくなるため自立する。   In order to make the pipe 7 self-supporting, when the pipe 7 is brought close to the cleaner body 1 and the hose connection portion 8 is rotated and the pipe 7 comes into contact with the hose 5, the pipe 7 is moved to the tilt limit position. Tilt. Thereby, the hose 5 hangs down along the pipe 7, and it becomes a self-supporting state with good stability. Further, when the pipe 7 is tilted forward to the rotation limit, the locking claw 13 is fitted into the locking groove 14 (see the dotted line in FIG. 5). At this time, the pipe 7 is tilted forward and is in a state of being balanced in the front-rear direction, the rotation of the joint base 36 is restricted, and the pipe 7 does not tilt in the left-right direction, so that it becomes independent.

また、ホース接続部８はパイプ７のハンドル１０の握り位置から約２０ｃｍに下方の位置に設けられているため、高い位置からホース５が接続される場合に比べ、パイプ７およびホース５を含めた重心が低く抑えられ、自立する安定性が向上する。したがって、簡単な操作で安定性の良い自立が可能な電気掃除機を得ることができる。   Moreover, since the hose connection part 8 is provided in the position below about 20 cm from the grip position of the handle 10 of the pipe 7, the pipe 7 and the hose 5 are included as compared with the case where the hose 5 is connected from a high position. The center of gravity is kept low, and the independence stability is improved. Therefore, it is possible to obtain a vacuum cleaner that can be self-supporting with good stability by a simple operation.

また、本実施の形態１ではパイプ７が自立する際、垂直状態よりもさらに吸込口体１２の前方へ傾斜限界角度を約１０度としているが、この限りではなく、パイプ７やホース５の重量やホース接続部８の導出方向等の条件によっては適切な角度に設定する必要がある。本実施の形態１では、この傾斜限界角度を５度〜２０度の範囲内に設定することにより、パイプ７およびホース５を含めた重心が吸込口体１２の中心に近接するため、使用者がハンドル１０から手を離した瞬間のパイプ７の揺れや外力によるパイプ７の倒れが生じにくくすることができる。   Further, in the first embodiment, when the pipe 7 is self-supporting, the inclination limit angle is set to about 10 degrees further forward of the suction port body 12 than in the vertical state. However, the present invention is not limited thereto, and the weight of the pipe 7 and the hose 5 is not limited. Depending on conditions such as the direction of the hose connection 8 and the lead-out direction, it is necessary to set the angle appropriately. In the first embodiment, by setting the tilt limit angle within a range of 5 degrees to 20 degrees, the center of gravity including the pipe 7 and the hose 5 is close to the center of the suction port body 12, and thus the user can It is possible to make it difficult for the pipe 7 to sway at the moment the hand is released from the handle 10 or to fall down due to external force.

なお、本実施の形態１では、ホース５はホース接続部８によりパイプ７に対して上下方向に回動可能に接続されているが、図７に示すように、ホース接続部８が回動しない構成でパイプ７に固定的に接続されている場合でも、パイプ７を吸込口体１２の前方への回動限界まで傾斜させたときのホース接続部８のパイプ７からの導出方向が水平方向かそれより下方に向くように構成することにより、上方に向いた状態に比べホース接続部８に作用する重力が軽減されるとともに重心の位置も低くなるため、パイプ７を自立させる際に安定性を向上させることができる。   In the first embodiment, the hose 5 is connected to the pipe 7 so as to be pivotable in the vertical direction by the hose connection portion 8, but the hose connection portion 8 does not rotate as shown in FIG. Even if the pipe 7 is fixedly connected in the configuration, the direction in which the hose connection portion 8 is led out from the pipe 7 when the pipe 7 is tilted to the limit of forward rotation of the inlet 12 is horizontal. By configuring it so as to face downward, the gravity acting on the hose connection portion 8 is reduced and the position of the center of gravity is lowered compared to the state facing upward, so that stability is ensured when the pipe 7 is self-supporting. Can be improved.

実施の形態２．
図８は本発明の実施の形態２に係る電気掃除機の使用中断時の状態を示す概略説明図である。なお、本実施の形態は、ホースとパイプに、互いに係合する係合部をそれぞれ設けた点で実施の形態１と異なっているが、その他の構成については実施の形態１と同一であるので、実施の形態１と同一部分には同じ符号を付し、詳細な説明は省略する。 Embodiment 2. FIG.
FIG. 8 is a schematic explanatory view showing a state when the use of the electric vacuum cleaner according to Embodiment 2 of the present invention is interrupted. Although this embodiment is different from the first embodiment in that the hose and the pipe are provided with engaging portions that engage with each other, the other configuration is the same as the first embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図において、４１はホース５に設けられた磁石であり、パイプ７が自立した際にパイプ７に設けられた鉄板４２に吸着するものである。この構成により、使用者がパイプ７を自立させるためにホース５に近接させると、ホース５がパイプ７に吸着して安定する。したがって、パイプ７を自立させる際のパイプ７とホース５の位置関係を容易に設定することができる。   In the figure, 41 is a magnet provided on the hose 5 and is attracted to an iron plate 42 provided on the pipe 7 when the pipe 7 is self-supporting. With this configuration, when the user brings the pipe 7 close to the hose 5 in order to be independent, the hose 5 is adsorbed to the pipe 7 and stabilized. Therefore, it is possible to easily set the positional relationship between the pipe 7 and the hose 5 when the pipe 7 is self-supporting.

ここで、磁石４１と鉄板４２の吸着力を１０ｇｆ〜２００ｇｆの範囲に設定することにより、パイプ７とホース５を容易に係合させることができるとともに、パイプ７を自立させた状態からパイプ７を前に押し出す際、例えば掃除を再度行う際に容易にホース５を離間させることが可能となる。   Here, by setting the attractive force of the magnet 41 and the iron plate 42 in the range of 10 gf to 200 gf, the pipe 7 and the hose 5 can be easily engaged, and the pipe 7 can be removed from the state in which the pipe 7 is self-supporting. When pushing forward, for example, when cleaning is performed again, the hose 5 can be easily separated.

なお、図８では、パイプ７に鉄板４２を設けた例を示したが、ホース５に設けられた磁石４１と逆向きの極性の磁石を用いてもよい。また、ホース５に鉄板を設け、パイプ７に磁石を設けてもよい。   In addition, although the example which provided the iron plate 42 in the pipe 7 was shown in FIG. 8, you may use the magnet of the polarity opposite to the magnet 41 provided in the hose 5. FIG. Moreover, an iron plate may be provided in the hose 5 and a magnet may be provided in the pipe 7.

また、ホース５とパイプ７の係合手段には磁性材料を利用する以外に、面状ファスナーを利用してもよく、同様の効果が得られる。   In addition to using a magnetic material for the engaging means of the hose 5 and the pipe 7, a planar fastener may be used, and the same effect can be obtained.

実施の形態３．
図９は本発明の実施の形態３に係る電気掃除機のパイプ下方の側面断面図、図１０は電気回路図である。なお、本実施の形態は、パイプを吸込口体の前方へ傾斜させた際に、電動送風機の駆動を停止する手段を備えた点で実施の形態１と異なっているが、その他の構成については実施の形態１と同一であるので、説明を省略する。 Embodiment 3 FIG.
FIG. 9 is a side cross-sectional view below the pipe of the vacuum cleaner according to Embodiment 3 of the present invention, and FIG. 10 is an electric circuit diagram. The present embodiment is different from the first embodiment in that it includes means for stopping the driving of the electric blower when the pipe is inclined forward of the suction port body. Since it is the same as Embodiment 1, description is abbreviate | omitted.

図において、係止爪１３内にはスイッチＡ４３が設けられており、パイプ７に設けられたパイプ内配線室４４に配設されたリード線４５、４６によってハンドル１０内のコントロール部２４に電気的に接続されている。なお、４７は商用電源である。   In the figure, a switch A 43 is provided in the locking claw 13 and is electrically connected to the control unit 24 in the handle 10 by lead wires 45, 46 disposed in a pipe wiring chamber 44 provided in the pipe 7. It is connected to the. Reference numeral 47 denotes a commercial power source.

パイプ７が吸込口体前方の回動限界まで傾斜して係止爪１３が係止溝１４（図５参照）に嵌合すると、スイッチＡ４３の先端部が係止溝１４の側面に接触してＯＦＦ状態となり、掃除機本体１の電動送風機４の駆動回路が遮断される。したがって、電気掃除機の使用者がパイプ７を自立させると、自動的に電動送風機４の運転を停止させることができる。また、使用者がパイプ７を後方に回動し係止溝１４との接触状態を解除すればスイッチＡ４３がＯＮ状態となり電動送風機４が駆動するため、掃除を再開することができる。   When the pipe 7 is inclined to the rotation limit in front of the suction port and the locking claw 13 is fitted into the locking groove 14 (see FIG. 5), the tip of the switch A43 comes into contact with the side surface of the locking groove 14. It will be in an OFF state and the drive circuit of the electric blower 4 of the cleaner body 1 will be shut off. Therefore, when the user of the vacuum cleaner makes the pipe 7 self-supporting, the operation of the electric blower 4 can be automatically stopped. If the user turns the pipe 7 rearward to release the contact state with the locking groove 14, the switch A43 is turned on and the electric blower 4 is driven, so that cleaning can be resumed.

なお、スイッチＡ４３の構成を接触タイプのもので説明したが、非接触タイプのスイッチで構成してもよい。   Although the configuration of the switch A43 has been described as a contact type, it may be configured as a non-contact type switch.

また、本実施の形態に示す電動送風機の駆動を停止する手段を実施の形態２に記載の構成に用いるようにしてもよい。   Further, the means for stopping the driving of the electric blower shown in the present embodiment may be used in the configuration described in the second embodiment.

実施の形態４．
図１１は本発明の実施の形態４に係る電気掃除機のパイプを自立させた状態を示す概略説明図である。なお、本実施の形態は、パイプを吸込口体の前方へ傾斜させた際に、電動送風機の駆動を停止する手段を備えた点で実施の形態１と異なっているが、その他の構成については実施の形態１と同一であるので、実施の形態１と同一部分には同じ符号を付し、詳細な説明は省略する。また、本実施の形態では、電動送風機の駆動を停止する手段として、傾斜センサを用いた例を示している。 Embodiment 4 FIG.
FIG. 11 is a schematic explanatory view showing a state where the pipe of the vacuum cleaner according to Embodiment 4 of the present invention is self-supporting. The present embodiment is different from the first embodiment in that it includes means for stopping the driving of the electric blower when the pipe is inclined forward of the suction port body. Since it is the same as that of the first embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, in this Embodiment, the example which used the inclination sensor as a means to stop the drive of an electric blower is shown.

図において、パイプ７上部には傾斜センサ４８が設けられており、ハンドル１０内の電動送風機の運転停止および出力制御を行うコントロール部に電気的に接続されている。傾斜センサ４８は内部に金属球体（図示せず）を有しており、パイプ７が吸込口体１２前方の回動限界まで傾斜すると金属球体が移動して傾斜センサ４８内のスイッチ部（図示せず）をＯＦＦ状態にすることにより電動送風機の駆動回路を遮断する。したがって、電気掃除機の使用者がパイプ７を自立させると、自動的に電動送風機の運転を停止させることができる。また、掃除を再開する場合は、使用者がパイプ７を後方に回動して傾斜センサ４８内のスイッチ部をＯＮ状態にして、再び電動送風機を駆動させる。   In the figure, an inclination sensor 48 is provided on the upper part of the pipe 7 and is electrically connected to a control unit for stopping the operation of the electric blower in the handle 10 and controlling the output. The inclination sensor 48 has a metal sphere (not shown) inside, and when the pipe 7 is inclined to the rotation limit in front of the suction port body 12, the metal sphere moves and a switch part (not shown) in the inclination sensor 48 is shown. Z) is turned off to shut off the drive circuit of the electric blower. Therefore, when the user of the vacuum cleaner makes the pipe 7 self-supporting, the operation of the electric blower can be automatically stopped. When cleaning is resumed, the user turns the pipe 7 rearward to turn on the switch portion in the inclination sensor 48 and drives the electric blower again.

なお、本実施の形態に示す電動送風機の駆動を停止する手段を、実施の形態２に記載の構成に用いるようにしてもよい。   Note that the means for stopping the driving of the electric blower described in the present embodiment may be used in the configuration described in the second embodiment.

実施の形態５．
図１２は本発明の実施の形態５に係る電気掃除機のパイプを自立させた状態を示す概略説明図である。なお、本実施の形態は、パイプを吸込口体の前方へ傾斜させた際に、電動送風機の駆動を停止する手段を備えた点で実施の形態１と異なっているが、その他の構成については実施の形態１と同一であるので、説明を省略する。また、本実施の形態では、電動送風機の駆動を停止する手段を設ける位置が上述した実施の形態３と異なっている。 Embodiment 5 FIG.
FIG. 12 is a schematic explanatory view showing a state where the pipe of the electric vacuum cleaner according to Embodiment 5 of the present invention is self-supporting. The present embodiment is different from the first embodiment in that it includes means for stopping the driving of the electric blower when the pipe is inclined forward of the suction port body. Since it is the same as Embodiment 1, description is abbreviate | omitted. Moreover, in this Embodiment, the position which provides the means to stop the drive of an electric blower differs from Embodiment 3 mentioned above.

図において、パイプ７のホース側表面にはスイッチＢ４９が設けられており、ハンドル１０内のコントロール部に接続されている。スイッチＢ４９はパイプ７が吸込口体前方の回動限界まで傾斜してホース接続管１８が接触するとＯＦＦ状態となり電動送風機の駆動回路を遮断する。したがって、電気掃除機の使用者がパイプ７を自立させると、自動的に電動送風機の運転を停止する。また、掃除を再開する場合はパイプ７を後方に回動してスイッチＢ４９をＯＮ状態して、再び電動送風機を駆動させる。   In the drawing, a switch B49 is provided on the hose side surface of the pipe 7 and is connected to a control unit in the handle 10. The switch B49 is turned off when the pipe 7 is tilted to the rotation limit in front of the suction port and the hose connection pipe 18 comes into contact, and the drive circuit of the electric blower is shut off. Therefore, when the user of the vacuum cleaner makes the pipe 7 self-supporting, the operation of the electric blower is automatically stopped. When cleaning is resumed, the pipe 7 is rotated rearward to turn on the switch B49, and the electric blower is driven again.

なお、スイッチＢ４９の構成を接触タイプのもので説明したが、非接触タイプのスイッチで構成してもよい。     Although the configuration of the switch B49 has been described as a contact type, it may be configured as a non-contact type switch.

また、本実施の形態に示す電動送風機の駆動を停止する手段を、実施の形態２に記載の構成に用いるようにしてもよい。   Further, the means for stopping the driving of the electric blower shown in the present embodiment may be used in the configuration described in the second embodiment.

実施の形態６．
図１３は本発明の実施の形態６に係る電気掃除機のパイプを自立させた状態を示す概略説明図、図１４はホースとパイプの接続部分の斜視図である。なお、本実施の形態は、ホースとパイプの接続部分の構成が実施の形態１と異なっているが、その他の構成については実施の形態１と同一であるので、実施の形態１と同一部分には同じ符号を付し、詳細な説明は省略する。 Embodiment 6 FIG.
FIG. 13 is a schematic explanatory view showing a state where the pipe of the electric vacuum cleaner according to Embodiment 6 of the present invention is self-supporting, and FIG. 14 is a perspective view of a connecting portion between the hose and the pipe. In this embodiment, the configuration of the connecting portion of the hose and the pipe is different from that of the first embodiment, but the other configuration is the same as that of the first embodiment. Are denoted by the same reference numerals, and detailed description thereof is omitted.

図において、 ５０はパイプ７の側面に上下方向回動可能に接続されたホース接続部であり、ハンドル１０の握り位置から約２０ｃｍ下方に設けられている。ホース接続部５０には、ホース５を円周方向回動可能に接続するホース接続管５１が設けられている。   In the figure, reference numeral 50 denotes a hose connection portion connected to the side surface of the pipe 7 so as to be rotatable in the vertical direction, and is provided approximately 20 cm below the grip position of the handle 10. The hose connection portion 50 is provided with a hose connection pipe 51 that connects the hose 5 so as to be rotatable in the circumferential direction.

ホース接続部５０は回動自在であるため、パイプ７の傾斜角度を変えてもホース接続部５０からのホース５の導出方向は下向きとなる。そして、パイプ７を前傾させて自立させる際、パイプ７にはホース接続部５０を介してホース５に作用する重力とホース５の湾曲状態からの復元力が加わる。このパイプ７に作用する力の大きさおよびその方向はパイプ７を前傾させて自立させる際の吸込口体１２と掃除機本体１間の距離によって変わり、距離が長いほどパイプ７を後方に引く力が大きくなり、距離が短いと前方に押す力が大きくなる。したがって、パイプ７を自立させるためには、パイプ７にホース５からの力が加わった状態でパイプ７の重心が吸込口体１２の前方車輪１５と後方車輪１７との間の上方に位置するように吸込口体１２と掃除機本体１間の距離を調節する必要がある。   Since the hose connection part 50 is rotatable, the direction in which the hose 5 is led out from the hose connection part 50 is downward even when the inclination angle of the pipe 7 is changed. When the pipe 7 is tilted forward to be self-supporting, the pipe 7 is subjected to the gravity acting on the hose 5 and the restoring force from the curved state of the hose 5 via the hose connection portion 50. The magnitude and direction of the force acting on the pipe 7 vary depending on the distance between the suction port body 12 and the cleaner body 1 when the pipe 7 is tilted forward to be independent, and the longer the distance, the more the pipe 7 is pulled backward. The force increases, and when the distance is short, the force pushing forward increases. Therefore, in order to make the pipe 7 self-supporting, the center of gravity of the pipe 7 is located above the front wheel 15 and the rear wheel 17 of the suction port body 12 with the force from the hose 5 applied to the pipe 7. It is necessary to adjust the distance between the suction port body 12 and the cleaner body 1.

実施の形態６では、ホース接続部５０をパイプ７側面に設けているため、パイプ７の吸気風路をホース５に連結した状態で３６０度回動可能であり、パイプ７をほぼ水平にして使用しても吸気が可能となる。また、パイプ７を吸込口体１２の前方へ傾斜させたときの限界角度を約１０度に設定しており、パイプ７をこの角度まで前傾させると、ホース接続管５１はほぼ鉛直下方に向き、ホース５がパイプ７の側面に垂れ下がった状態となる。この状態において、パイプ７の重心は吸込口体１２の前方車輪１５と後方車輪１７間の上方に位置するように構成されている。したがって、パイプ７は安定して自立する。   In the sixth embodiment, since the hose connection portion 50 is provided on the side surface of the pipe 7, it can be rotated 360 degrees with the intake air passage of the pipe 7 connected to the hose 5, and the pipe 7 is used in a substantially horizontal state. Even if it can inhale. Further, the limit angle when the pipe 7 is tilted forward of the suction port body 12 is set to about 10 degrees, and when the pipe 7 is tilted forward to this angle, the hose connecting pipe 51 is directed substantially vertically downward. The hose 5 is hung from the side surface of the pipe 7. In this state, the center of gravity of the pipe 7 is configured to be positioned above the front wheel 15 and the rear wheel 17 of the suction port body 12. Accordingly, the pipe 7 is stable and independent.

なお、本実施の形態に示すホースとパイプの接続部分の構成を、実施の形態２〜５に記載の構成に用いるようにしてもよい。   In addition, you may make it use the structure of the connection part of the hose and pipe shown to this Embodiment for the structure as described in Embodiment 2-5.

実施の形態７．
以下にホース接続部のロック機構の参考例を記載します。図１５は本発明の実施の形態７に係る電気掃除機のパイプを自立させた状態を示す概略説明図、図１６はパイプ上部の側面断面図である。なお、本実施の形態は、パイプのホースが導出される位置よりも下方に、パイプを屈折させる手段を設けた点が、上述した実施の形態と異なっている。ここでは、実施の形態１と同一または相当する部分には同じ符号を付し、詳細な説明は省略する。 Embodiment 7 FIG.
The following is a reference example of the locking mechanism for the hose connection. FIG. 15 is a schematic explanatory view showing a state where a pipe of a vacuum cleaner according to Embodiment 7 of the present invention is self-supporting, and FIG. 16 is a side sectional view of the upper part of the pipe. This embodiment is different from the above-described embodiment in that a means for bending the pipe is provided below the position where the hose of the pipe is led out. Here, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図１５において、ホース接続管１８ａの先端部はパイプ７に接続されている。パイプ７はホース接続管１８ａと接続する位置でハンドル１０と分割されており、ハンドル１０はヒンジ５２を支点にパイプ７に屈折可能に設けられている。図１６に示すように通常の使用状態において、パイプ７とハンドル１０はラッチ爪５３とラッチ溝５４が嵌合することによって接続されている。パイプ７とハンドル１０の分割面にはパッキン５５が設けられ、空気が洩れないように構成されている。ラッチ爪５３はハンドル１０に設けられたワイヤー５６を介してハンドル１０上部に設けられたレバー５７に連結されており、レバー５７を後方に引くことによりラッチ５３がラッチ溝５４から引き出され、ハンドル１０が屈折可能となる。ラッチ爪５３はバネ５８によって突出するように付勢されているため、レバー５７は手を放すことにより元の位置に戻るように構成されている。また、レバー５７を後方に引くことにより操作されるスイッチ５９が設けられている。実施の形態７では、スイッチ５９をレバー５７に隣接させ、接触によりＯＮ状態とＯＦＦ状態が切り替わるトグル型のスイッチで構成している。例えばスイッチ５９はレバー５７が後方に引かれてワイヤー５６と接触するとＯＦＦ状態となり、掃除機本体内の電動送風機の駆動回路を遮断する。   In FIG. 15, the tip of the hose connection pipe 18 a is connected to the pipe 7. The pipe 7 is divided from the handle 10 at a position where the pipe 7 is connected to the hose connecting pipe 18a, and the handle 10 is provided so as to be refracted to the pipe 7 with a hinge 52 as a fulcrum. As shown in FIG. 16, in a normal use state, the pipe 7 and the handle 10 are connected by fitting the latch claw 53 and the latch groove 54 together. A packing 55 is provided on the dividing surface of the pipe 7 and the handle 10 so that air does not leak. The latch claw 53 is connected to a lever 57 provided on the upper portion of the handle 10 via a wire 56 provided on the handle 10. By pulling the lever 57 rearward, the latch 53 is pulled out from the latch groove 54. Can be refracted. Since the latch claw 53 is biased so as to protrude by the spring 58, the lever 57 is configured to return to its original position when the hand is released. Further, a switch 59 that is operated by pulling the lever 57 backward is provided. In the seventh embodiment, the switch 59 is adjacent to the lever 57, and is configured by a toggle type switch that switches between an ON state and an OFF state by contact. For example, the switch 59 is turned off when the lever 57 is pulled backward and comes into contact with the wire 56, and the drive circuit of the electric blower in the cleaner body is shut off.

パイプ７を自立させる際は、まずレバー５７を後方に引き、ラッチ爪５３とラッチ溝５４との嵌合を解除させてハンドル１０を屈折させる。電動送風機の駆動状態からレバー５７を引いた場合、ハンドル１０の屈折動作に連動して電動送風機４も停止する。この状態からパイプ７を前方の回動限界まで傾斜させ、ハンドル１０がヒンジ５２にぶら下がった状態で自立させる。このとき、ハンドル１０がヒンジ５２よりも下方に移動することにより重心が下方に移動するため、パイプ７を自立させる際の安定性が向上する。   When the pipe 7 is self-supporting, first, the lever 57 is pulled backward to release the fitting between the latch claw 53 and the latch groove 54 to refract the handle 10. When the lever 57 is pulled from the driving state of the electric blower, the electric blower 4 is also stopped in conjunction with the bending operation of the handle 10. From this state, the pipe 7 is inclined to the forward rotation limit, and the handle 10 is made to stand by itself while being hung on the hinge 52. At this time, since the center of gravity moves downward by moving the handle 10 below the hinge 52, the stability when the pipe 7 is self-supporting is improved.

また、掃除を再開する際はレバー５７を再度後方に引きながらハンドル１０を持ち上げて、パイプ７に接続する。このとき、レバー５７によってスイッチ５９がＯＮ状態となり、電動送風機４が駆動する。   Further, when cleaning is resumed, the handle 10 is lifted while pulling the lever 57 back again and connected to the pipe 7. At this time, the switch 59 is turned on by the lever 57, and the electric blower 4 is driven.

なお、本実施の形態に示すパイプを屈折させる手段を、実施の形態２〜６の構成に用いるようにしてもよい。   In addition, you may make it use the means to refract the pipe shown in this Embodiment for the structure of Embodiment 2-6.

実施の形態８．
図１７は本発明の実施の形態８に係る電気掃除機のパイプを自立させた状態を示す概略説明図、図１８はパイプ上部の斜視図、図１９はパイプ上部の側面断面図である。なお、本実施の形態は、パイプのホースが導出される位置よりも下方に、パイプを屈折させる手段を設けた点が、上述した実施の形態と異なっている。ここでは、実施の形態１と同一または相当する部分には同じ符号を付し、詳細な説明は省略する。 Embodiment 8 FIG.
FIG. 17 is a schematic explanatory view showing a state where a pipe of a vacuum cleaner according to Embodiment 8 of the present invention is self-supporting, FIG. 18 is a perspective view of the upper part of the pipe, and FIG. 19 is a side sectional view of the upper part of the pipe. This embodiment is different from the above-described embodiment in that a means for bending the pipe is provided below the position where the hose of the pipe is led out. Here, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図１７、図１８において、ホース接続管１８ａはパイプ屈折部６０により回動可能にパイプ７に接続されている。また、ホース接続管１８ａはパイプ屈折部６０の屈折部内筒６１に接続されており、パイプ７とホース５の風路はパイプ屈折部６０によって連結される。ハンドル１０はパイプ屈折部６０の屈折部外筒６２に着脱可能に接続されており、パイプ屈折部６０を支点にパイプ７に屈折可能に設けられている。また、ハンドル１０とホース接続管１８ａとは一体的に形成されており、ハンドル１０の屈折動作に応じてホース接続管１８ａも回動する。   17 and 18, the hose connection pipe 18 a is connected to the pipe 7 so as to be rotatable by a pipe bending portion 60. Further, the hose connecting pipe 18 a is connected to the refracting portion inner cylinder 61 of the pipe refracting portion 60, and the air path between the pipe 7 and the hose 5 is connected by the pipe refracting portion 60. The handle 10 is detachably connected to the refracting portion outer cylinder 62 of the pipe refracting portion 60, and is refracted to the pipe 7 with the pipe refracting portion 60 as a fulcrum. Further, the handle 10 and the hose connection pipe 18a are integrally formed, and the hose connection pipe 18a also rotates according to the bending operation of the handle 10.

パイプ７とハンドル１０は、図１８に示すように通常の使用状態において、ハンドル１０側に設けたラッチ爪５３と屈折部外筒６１の端部に設けられたフック６３との嵌合によって接続されている。ラッチ爪５３はハンドル１０に設けたワイヤー５６を介してハンドル１０上部に設けたレバー５７に連結しており、レバー５７を後方に引くことでラッチ５３がフック６３との嵌合を解除されてハンドル１０が屈折可能となる。また、ハンドル１０を屈折する際、ホース接続管１８ａに接続された屈折部内筒６１が屈折部外筒６２に沿って摺動することでホースも屈折する。また、ラッチ爪５３はバネ５８によって突出するように付勢されているため、レバー５７から手を放すことにより元の位置に戻るように構成されている。   As shown in FIG. 18, the pipe 7 and the handle 10 are connected by fitting a latch claw 53 provided on the handle 10 side and a hook 63 provided at the end of the refracting portion outer cylinder 61 in a normal use state. ing. The latch claw 53 is connected to a lever 57 provided on the upper portion of the handle 10 via a wire 56 provided on the handle 10, and the latch 53 is released from fitting with the hook 63 by pulling the lever 57 rearward. 10 can be refracted. Further, when the handle 10 is refracted, the hose is also refracted as the refracting portion inner cylinder 61 connected to the hose connecting pipe 18 a slides along the refracting portion outer cylinder 62. Further, since the latch claw 53 is biased so as to protrude by the spring 58, the latch claw 53 is configured to return to the original position when the lever 57 is released.

なお、ハンドル屈折時の電動送風機の駆動および停止動作は、実施の形態７と同様であるので、説明を省略する。   In addition, since the drive and stop operation | movement of an electric blower at the time of steering wheel refraction are the same as that of Embodiment 7, explanation is omitted.

また、本実施の形態に示すパイプを屈折させる手段を、実施の形態２〜６の構成に用いるようにしてもよい。   Moreover, you may make it use the means to refract the pipe shown in this Embodiment for the structure of Embodiment 2-6.

実施の形態９．
図２０は本発明の実施の形態９に係る電気掃除機の吸込口体の平面図、図２１は側面図である。なお、本実施の形態は、吸込口体と床面との接触点間隔を広くする手段を設けた点が、上述した実施の形態と異なっているが、その他の構成については、特に限定せず、上述した実施の形態の構成に用いるようにすればよい。ここでは、実施の形態１と同一部分には同じ符号を付し、説明を省略する。 Embodiment 9 FIG.
20 is a plan view of a suction port body of a vacuum cleaner according to Embodiment 9 of the present invention, and FIG. 21 is a side view. The present embodiment is different from the above-described embodiment in that a means for widening the contact point interval between the suction port body and the floor surface is provided, but the other configurations are not particularly limited. What is necessary is just to use it for the structure of embodiment mentioned above. Here, the same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

図２０、図２１において、吸込口体１２上部には吸込口体１２の上部から両側面に伸びる可動アーム６４が前後方向摺動可能に設けられている。可動アーム６４には可動係止部材６５が設けられており、パイプ７が前方に回動されるとパイプ７下部に設けられた係止爪１３が可動係止部材６５と嵌合し、可動アーム６４を前方に押し出す。そして、可動アーム６４が前方に押し出される際、可動アーム６４側面に設けられた突起６６が吸込口体１２側面に設けられたガイド６７の溝に導かれ水平に移動する。可動アーム６４の先端には一対の可動車輪６８が設けられており、可動アーム６４が前方に押し出される際、吸込口体１２の前方に突出する構成になっている。   20 and 21, a movable arm 64 extending from the upper portion of the suction port body 12 to both side surfaces is provided on the upper portion of the suction port body 12 so as to be slidable in the front-rear direction. The movable arm 64 is provided with a movable locking member 65. When the pipe 7 is rotated forward, the locking claw 13 provided at the lower portion of the pipe 7 is fitted with the movable locking member 65, and the movable arm is moved. Push 64 forward. When the movable arm 64 is pushed forward, the projection 66 provided on the side surface of the movable arm 64 is guided to the groove of the guide 67 provided on the side surface of the suction port body 12 and moves horizontally. A pair of movable wheels 68 are provided at the distal end of the movable arm 64, and are configured to protrude forward of the suction port body 12 when the movable arm 64 is pushed forward.

また、可動アーム６４は吸込口体１２上部に設けられたストッパー６９によって前方への移動を制限されており、可動係止部材６５がストッパー６９に当接する位置がパイプ７の前方への回動限界となる。   Further, the movable arm 64 is restricted from moving forward by a stopper 69 provided on the upper portion of the suction port body 12, and the position where the movable locking member 65 abuts against the stopper 69 is the limit for turning the pipe 7 forward. It becomes.

実施の形態９では、パイプ７が回動限界まで傾斜して自立する際、一対の可動車輪６８が吸込口体１２の前方に突出し、可動車輪６８と後方車輪１７間の幅が通常の使用状態よりも広くなるため、パイプ７の安定性が向上する。   In the ninth embodiment, when the pipe 7 is tilted to the limit of rotation and is self-supporting, the pair of movable wheels 68 protrudes in front of the suction port body 12, and the width between the movable wheels 68 and the rear wheels 17 is a normal use state. Therefore, the stability of the pipe 7 is improved.

また、掃除の再開によりパイプ７が後方に戻されると、ストッパー６９に取り付けられたバネ７０の復元力により、可動係止部材６５および可動アーム６４が元の位置に戻されるため、可動車輪６８は吸込口体１２前方への突出しなくなり、吸込口体１２を移動させる際の邪魔にはならない。このとき、バネ７０の付勢力はパイプ７が自立する際に係止爪１３に加わる力よりも弱く設定されているため、可動アーム６４はパイプ７の回動に連動して前後に移動可能となる。   Further, when the pipe 7 is returned to the rear by resuming the cleaning, the movable locking member 65 and the movable arm 64 are returned to the original positions by the restoring force of the spring 70 attached to the stopper 69. The suction port body 12 does not protrude forward and does not interfere with the movement of the suction port body 12. At this time, since the urging force of the spring 70 is set to be weaker than the force applied to the locking claw 13 when the pipe 7 is self-supporting, the movable arm 64 can move back and forth in conjunction with the rotation of the pipe 7. Become.

なお、本実施の形態９では床面に接する車輪の前後の間隔を広げるように構成しているが、前後に限るものでなく、横方向に広げることにより自立したパイプ７の横方向への安定性を向上させる構成にしてもよい。また、車輪によって床面に接する構成としているが、フレームのような構造部材によって接する構成としても同様の効果が得られる。   In the ninth embodiment, the front-rear distance between the wheels in contact with the floor surface is increased. However, the present invention is not limited to the front-rear direction. The structure may be improved. Moreover, although it is set as the structure which contacts a floor surface with a wheel, the same effect is acquired also as a structure which contacts with structural members like a flame | frame.

実施の形態１０．
図２２は本発明の実施の形態１０に係る電気掃除機の収納形態を示す側面説明図である。なお、本実施の形態は掃除機本体の後方下部と吸込口体の前部、及び掃除機本体の前方下部とパイプに、互いに係合する係合部をそれぞれ設けた点が、上述した実施の形態と異なっている。ここでは、実施の形態１と同一または相当する部分には同じ符号を付し、詳細な説明は省略する。 Embodiment 10 FIG.
FIG. 22 is an explanatory side view showing the storage form of the electric vacuum cleaner according to Embodiment 10 of the present invention. In addition, this embodiment has the above-described embodiment in that the rear lower part of the cleaner body and the front part of the suction port body, and the front lower part of the cleaner body and the pipe are provided with engaging portions that engage with each other.

And it rotates to the suction inlet 12 side. When the concave portion 81 is fitted to the locking portion 80 and the locking claw 13 is engaged with the locking groove 14, the contact portion 97b rotates forward of the suction port body 12, so that the shaft support portion 98 is used as an axis. The contact portion 97a pushes out the movable portion 89, and the operating rod 96 protrudes from the end portion 88a of the base portion 88 against the spring force. Then, when the movable part 89 slides, the contact point between the rear wheel 17 and the floor surface moves to the rear of the joint 77, and the distance between the contact points, that is, the distance between the front wheel 15 and the rear wheel 17 increases, and the pipe 7 is set up. Sometimes it becomes stable.

一方、パイプ７を回動させて係止部８０と凹部８１の嵌合を解除すれば、操作棒９６がバネ力で基部８８内に収納され可動部８９は元の位置に戻る。したがって、通常の掃除をするとき等、可動支持体９５がじゃまになることはない。また、可動支持体９５を広げる必要がないときは、係止爪１３と係止溝１４の係合を外し、係止部８０と凹部８１の嵌合を解除するだけでよく、操作性がよい。   On the other hand, when the pipe 7 is rotated to release the engagement between the locking portion 80 and the recess 81, the operating rod 96 is housed in the base 88 by the spring force, and the movable portion 89 returns to its original position. Therefore, the movable support body 95 is not disturbed during normal cleaning. Further, when it is not necessary to widen the movable support body 95, it is only necessary to disengage the engaging claw 13 and the engaging groove 14 and release the engagement between the engaging portion 80 and the recessed portion 81, and the operability is good. .

本実施の形態では、吸込口体１２と床面の接触点の間隔を通常の使用状態よりも広くしたい場合には、パイプ７で操作体９７を回動させ、可動部８９を押し出す。そして、後方車輪１７と床面との接点が継手７７後方に移動したことでパイプ７を自立させたときに安定する。また、吸込口体１２と床面の接触点の間隔を通常の使用状態に戻す場合には、パイプ７を回動させて係止部８０と凹部８１の嵌合を解除するだけでよく、掃除をするとき等、可動支持体８７がじゃまになることはない。   In the present embodiment, when it is desired to make the distance between the contact point between the suction port body 12 and the floor surface wider than the normal use state, the operating body 97 is rotated by the pipe 7 and the movable portion 89 is pushed out. Then, the contact between the rear wheel 17 and the floor surface is moved to the rear of the joint 77, so that the pipe 7 is stabilized when it becomes self-supporting. In addition, when the interval between the contact points of the suction port body 12 and the floor surface is returned to the normal use state, it is only necessary to rotate the pipe 7 to release the engagement between the locking portion 80 and the recessed portion 81, and to clean it. For example, the movable support 87 is not obstructed when performing the operation.

なお、操作棒９６を押し出すバネの付勢力は係止部８０と凹部８１の嵌合力よりも弱く設定されている。   The urging force of the spring that pushes out the operating rod 96 is set to be weaker than the fitting force between the locking portion 80 and the recess 81.

実施の形態１６．
図３７は本発明の実施の形態１６に係る電気掃除機の吸込口体を示す斜視図、図３８は可動支持体の動作を示す吸込口体の側面図である。なお、本実施の形態は、吸込口体の構成が、上述した実施の形態と異なっているが、その他の構成については、特に限定せず、上述した実施の形態の構成に用いるようにすればよい。ここでは、一例として実施の形態１の構成を用いて説明する。 Embodiment 16 FIG.
FIG. 37 is a perspective view showing a suction port body of a vacuum cleaner according to Embodiment 16 of the present invention, and FIG. 38 is a side view of the suction port body showing the operation of the movable support. In addition, although this Embodiment differs in the structure of a suction inlet body from embodiment mentioned above, it does not specifically limit about another structure, If it is made to use for the structure of embodiment mentioned above. Good. Here, the configuration of the first embodiment will be described as an example.

図３７において、吸込口体１２と床面の接触点の間隔を広くする手段の一例を示す可動支持体９９は、吸込口体１２後方で継手７７より下方に設けられた基部８８と、基部８８の側面を摺動する略コ字状の可動部８９と、可動部８９の先端に設けた後方車輪１７を備えている。可動部８９は、基部８８の両側に設けられた凸状のレール８５に沿って摺動する溝８６を備えている。また、可動部８９の端部８９ａには、基部８８の端部８８ａから出没する操作棒９０が設けられている。操作棒９０は、基部８８の内部に設けられたバネ（図示せず）によって突出する方向に付勢されている。   In FIG. 37, a movable support 99 showing an example of means for widening the contact point between the suction port 12 and the floor surface includes a base 88 provided below the joint 77 behind the suction port 12 and a base 88. A substantially U-shaped movable part 89 that slides on the side surface of the movable part 89 and a rear wheel 17 provided at the tip of the movable part 89 are provided. The movable portion 89 includes a groove 86 that slides along a convex rail 85 provided on both sides of the base portion 88. An operation rod 90 that protrudes and protrudes from the end portion 88 a of the base portion 88 is provided at the end portion 89 a of the movable portion 89. The operation rod 90 is urged in a protruding direction by a spring (not shown) provided inside the base 88.

また、可動部８９の両側には吸込口体１２の前進方向にのみ作用するクラッチ１００が設けられている。クラッチ１００は、基部８８上を移動する従動輪１０１と、床面上を移動する原動輪１０２とを有し、可動部８９と一体的に構成された固定部１０３により支持されている。従動輪１０１及び原動輪１０２は、例えば摩擦係数の高いゴムなどの弾性部材で形成されている。また、基部８８の吸込口体１２側端部には、従動輪１０１を受ける収納体８８ｂが形成されており、従動輪１０１が収納体８８ｂに収まると基部８８から離れるので、その状態では原動輪１０２が前後方向どちらの方向に回転しても基部８８上を移動しない構成となっている。   Further, on both sides of the movable portion 89, clutches 100 that act only in the forward direction of the suction port body 12 are provided. The clutch 100 includes a driven wheel 101 that moves on a base 88 and a driving wheel 102 that moves on a floor surface, and is supported by a fixed portion 103 that is configured integrally with a movable portion 89. The driven wheel 101 and the driving wheel 102 are formed of an elastic member such as rubber having a high friction coefficient, for example. A storage body 88b that receives the driven wheel 101 is formed at the end of the base portion 88 on the suction port body 12 side. When the driven wheel 101 is received in the storage body 88b, the storage body 88b is separated from the base portion 88. The structure is such that the base portion 88 does not move regardless of which direction the front and rear 102 rotate.

吸込口体１２の後方に軸支されたラッチ９４は、実施の形態１４と同様な構成であり、可動部８９の切欠部９３と係合する２つの係止部９４ａと、係止部９４ａを連結する略コ字状の操作部９４ｂからなる。図３８（ａ）（ｂ）に示すように、操作部９４ｂが吸込口体１２方向へ回動すると係止部９４ａは切欠部９３から外れ、操作棒９０のバネ力によって可動部８９が矢印Ｂ方向へ摺動する。このときクラッチ１００の原動輪１０２が床面と接触しているままだと抵抗がかかってしまうため、原動輪１０２が床面と接触しないように若干床面から浮かすとよい。操作部９４ｂは、パイプ７が床面に対して略垂直となる位置でパイプ７と当接し、パイプ７が吸込口体１２前方に傾斜する動作に連動して吸込口体１２側に回動する。そして、係止部８０に凹部８１が嵌合し、係止爪１３が係止溝１４に係止され、係止部９４ａと切欠部９３との係合は解除される。これにより、可動部８９がバネ力により引き出され、後方車輪１７と床面との接点が継手７７後方に移動し、接触点間隔、すなわち前方車輪１５と後方車輪１７との間隔が広くなり、パイプ７を立てたときに安定する。   The latch 94 pivotally supported on the rear side of the suction port body 12 has the same configuration as that of the fourteenth embodiment, and includes two locking portions 94a that engage with the cutout portions 93 of the movable portion 89, and a locking portion 94a. It comprises a substantially U-shaped operating portion 94b to be connected. As shown in FIGS. 38A and 38B, when the operation portion 94b rotates in the direction of the suction port body 12, the locking portion 94a is detached from the notch portion 93, and the movable portion 89 is moved to the arrow B by the spring force of the operation rod 90. Slide in the direction. At this time, if the driving wheel 102 of the clutch 100 remains in contact with the floor surface, resistance is applied. Therefore, the driving wheel 102 may be slightly lifted from the floor surface so as not to contact the floor surface. The operation portion 94b contacts the pipe 7 at a position where the pipe 7 is substantially perpendicular to the floor surface, and rotates toward the suction port body 12 in conjunction with the operation of the pipe 7 tilting forward of the suction port body 12. . And the recessed part 81 fits into the latching | locking part 80, the latching claw 13 is latched by the latching groove 14, and engagement with the latching | locking part 94a and the notch part 93 is cancelled | released. As a result, the movable portion 89 is pulled out by the spring force, the contact point between the rear wheel 17 and the floor surface moves to the rear of the joint 77, and the contact point interval, that is, the interval between the front wheel 15 and the rear wheel 17 increases. Stable when 7 is raised.

可動部８９がバネ力により引き出された状態で、パイプ７を倒す方向に回動させて係止爪１３を係止溝１４から外し、係止部８０と凹部８１の嵌合を解除し、通常の掃除を行えば、図３８の（ｃ）（ｄ）（ｅ）に示すように、吸込口体１２の前進移動に伴なってクラッチ１００の原動輪１０２が回転する。そして、原動輪１０２の回転に連動して従動輪１０１が基部８８上を移動し、吸込口体１２側に向かっていく。この移動により、固定部１０３を介して可動部８９が吸込口体１２側に移動するように構成されている。なお、吸込口体１２が後進しても原動輪１０２の逆方向回転により、従動輪１０１が回転することがないため、基部８８が後方に移動することはない。そして、可動部８９の切欠部９３と係止部９４ａが係合した後、従動輪１０１が収納体８８ｂに収まり、可動体８９は元の位置に戻る。   In a state where the movable portion 89 is pulled out by the spring force, the pipe 7 is rotated in the direction of tilting to remove the locking claw 13 from the locking groove 14, and the engagement between the locking portion 80 and the recess 81 is released. As shown in FIGS. 38 (c), (d), and (e), the driving wheel 102 of the clutch 100 rotates as the suction port body 12 moves forward. Then, the driven wheel 101 moves on the base 88 in conjunction with the rotation of the driving wheel 102 and moves toward the suction port body 12 side. By this movement, the movable portion 89 is configured to move toward the suction port body 12 via the fixed portion 103. Even if the suction port body 12 moves backward, the driven wheel 101 does not rotate due to the reverse rotation of the driving wheel 102, so that the base 88 does not move backward. And after the notch part 93 and the latching | locking part 94a of the movable part 89 engage, the driven wheel 101 is settled in the storage body 88b, and the movable body 89 returns to the original position.

本実施の形態では、吸込口体１２と床面の接触点の間隔を通常の使用状態よりも広くしたい場合には、ラッチ９４の操作部９４ｂをパイプ７で回動させて、係止部９４ａと切欠部９３との係合を外すことで、可動部８９が摺動する。そして、後方車輪１７と床面との接点が継手７７後方に移動したことでパイプ７を自立させたときに安定する。また、吸込口体１２と床面の接触点の間隔を通常の使用状態に戻す場合には、パイプ７を回動させて係止部８０と凹部８１の嵌合を解除させて吸込口体１２を前進させるだけでよく、掃除をするとき等、可動支持体９９がじゃまになることはない。つまり、クラッチ１００を設けたことにより、可動支持体９９を通常の使用状態に戻すときは、吸込口体１２を移動させるだけでよく、使い勝手がよい。   In this embodiment, when the interval between the contact points between the suction port body 12 and the floor surface is desired to be wider than in a normal use state, the operation portion 94b of the latch 94 is rotated by the pipe 7 and the locking portion 94a. The movable part 89 slides by releasing the engagement between the cutout part 93 and the cutout part 93. Then, the contact between the rear wheel 17 and the floor surface is moved to the rear of the joint 77, so that the pipe 7 is stabilized when it becomes self-supporting. Further, when the interval between the contact points between the suction port body 12 and the floor surface is returned to the normal use state, the pipe 7 is rotated to release the engagement between the locking portion 80 and the recessed portion 81 and the suction port body 12. The movable support 99 does not get in the way of cleaning. That is, when the movable support body 99 is returned to the normal use state by providing the clutch 100, it is only necessary to move the suction port body 12, which is convenient.

なお、クラッチ１００の構成は本実施の形態に示すものに限ったものではなく、例えば基部上にラックを形成し、従動輪にピニオンギアを用いてもよい。   The configuration of the clutch 100 is not limited to that shown in the present embodiment. For example, a rack may be formed on the base and a pinion gear may be used as the driven wheel.

上述した可動支持体の構成に関する各実施の形態では、可動支持体の形状を基部と略コ字状の可動部としたが、実施の形態１７に示す可動支持体は、継手７７の下部に摺動する摺動板１０４と、摺動板１０４の両側に設けられ吸込口体１２後方に固定された基部１０５と、基部１０５の先端部に設けられた車輪１０６とを備えている。基部１０５には摺動板１０４が摺動するレール１０７が形成されている。そして、パイプ７を自立させる際、基部１０５から摺動板１０４を引き出しておけば、自立状態が不安定になっても摺動板１０４が床面に接触してパイプ７の安定性は向上する。   In each of the embodiments related to the configuration of the movable support described above, the shape of the movable support is a substantially U-shaped movable part. However, the movable support shown in the seventeenth embodiment is slid under the joint 77. A sliding plate 104 that moves, a base portion 105 that is provided on both sides of the sliding plate 104 and is fixed to the rear of the suction port body 12, and a wheel 106 that is provided at the tip of the base portion 105 are provided. A rail 107 on which the sliding plate 104 slides is formed on the base portion 105. When the pipe 7 is self-supported, if the sliding plate 104 is pulled out from the base portion 105, the sliding plate 104 contacts the floor surface even if the self-standing state becomes unstable, and the stability of the pipe 7 is improved. .
