なお、図5(b)は、アーム6が限界まで伸展した状態、すなわち、直線状態を示している。図5(b)の状態をアーム6が突出位置にあるという。この場合は、先端経路6cと3つの中空経路6dとはかみ合った状態になっており、先端経路6cから一番遠い中空経路6dの集塵口6eが吸引経路20と接続される。 Note that FIG. 5B shows a state in which the arm 6 is extended to the limit, that is, a linear state. The state of FIG. 5B is said to be the state in which the arm 6 is in the protruding position. In this case, the tip path 6c and the three hollow paths 6d are in mesh with each other, and the dust collection port 6e of the hollow path 6d farthest from the tip path 6c is connected to the suction path 20.

中空経路6dと先端経路6cとがかみ合うと、中空経路6dの先端部6mの一部が先端経路6c内に入り込む。入り込んだ先端部6mは切替弁6kを押し上げて、切替弁6kは集塵口6eを閉じることとなる。先端経路6cから一番遠い中空経路6d以外の中空経路6dの集塵口6eは同様に次の中空経路6dの先端部6mによって切替弁6kを押し上げられ、アーム6の途中の集塵口6eはすべて閉じられることで、吸引口6aで吸い込まれたゴミが吸引経路20にまで運ばれ、集塵ボックス3に運ばれることになる。 When the hollow path 6d and the tip path 6c are engaged, a part of the tip portion 6m of the hollow path 6d enters the tip path 6c. The tip portion 6m that has entered pushes up the switching valve 6k, and the switching valve 6k closes the dust collecting port 6e. Similarly, the dust collection port 6e of the hollow path 6d other than the hollow path 6d farthest from the tip path 6c is pushed up by the tip portion 6m of the next hollow path 6d, and the dust collection port 6e in the middle of the arm 6 is pushed up. When all of them are closed, the dust sucked by the suction port 6a is carried to the suction path 20 and is carried to the dust collection box 3.

制御装置10はアーム6の前進および後進の程度、すなわち、進退の程度を調整することが可能である。1番目の中空経路6dに設けられた集塵口6eと吸引経路20が連通接
続されるように調整することも可能であるし、2番目の中空経路6dに設けられた集塵口6eと吸引経路20が連通接続されるように調整することも可能である。これらの場合は、アーム6は収納位置でも突出位置でもなく、その中間の位置にあると表現する。このような場合でも吸引口6aと集塵ボックス3とは連通接続され、それ以外の接続口6jや使われていない集塵口6eは切替弁6kによって全て閉じられる。
The control device 10 can adjust the degree of forward and backward movement of the arm 6, that is, the degree of advancement and retreat. It is also possible to adjust so that the dust collection port 6e provided in the first hollow path 6d and the suction path 20 are connected to each other, and the dust collection port 6e provided in the second hollow path 6d and suction can be adjusted. It is also possible to adjust so that the route 20 is connected in a communicative manner. In these cases, it is expressed that the arm 6 is not in the storage position or the protruding position, but in the intermediate position. Even in such a case, the suction port 6a and the dust collection box 3 are connected in communication, and the other connection ports 6j and the unused dust collection port 6e are all closed by the switching valve 6k.

アーム駆動装置7は、モータ7aおよびピニオン7b、アーム6に固定された湾曲変形可能なラック7cとからなっている。 The arm driving device 7 includes a motor 7a, a pinion 7b, and a bendable and deformable rack 7c fixed to the arm 6.

狭所判定センサ8は、複数の赤外線センサ素子からなっている。この狭所判定センサ8は掃除機本体1の前面に、4つの高さと5つの幅を検知するために4×5の格子の交点上に赤外線センサ素子が配置されており、掃除機本体1の前方にある障害物の形状を、認識することが可能である。図3(a)および(b)に示すように、掃除機本体1の左側から赤外線センサ素子列を一まとめに素子群8a、素子群8b、素子群8c、素子群8d、素子群8eと呼ぶ。右の2列の素子群8dおよび素子群8eはアーム6のごく近傍のそれぞれ左側および右側に配置されている。また、図7は、掃除機本体1のほぼ中央で切断した断面図を示しているが、ここで見えている素子列は素子群8cとなる。素子群8cの中で一番上の素子を素子8c1、2番目の素子を素子8c2、3番目の素子を素子8c3、4番目の素子を素子8c4というように呼ぶ。 The narrow space determination sensor 8 is composed of a plurality of infrared sensor elements. In this narrow space determination sensor 8, an infrared sensor element is arranged on the intersection of 4 × 5 grids in order to detect four heights and five widths on the front surface of the vacuum cleaner main body 1, and the vacuum cleaner main body 1 has an infrared sensor element. It is possible to recognize the shape of an obstacle in front. As shown in FIGS. 3A and 3B, the infrared sensor element trains are collectively referred to as an element group 8a, an element group 8b, an element group 8c, an element group 8d, and an element group 8e from the left side of the vacuum cleaner main body 1. .. The element group 8d and the element group 8e in the right two rows are arranged on the left side and the right side, respectively, in the immediate vicinity of the arm 6. Further, FIG. 7 shows a cross-sectional view cut at substantially the center of the vacuum cleaner main body 1, and the element row visible here is the element group 8c. In the element group 8c, the uppermost element is referred to as element 8c1, the second element is referred to as element 8c2, the third element is referred to as element 8c3, and the fourth element is referred to as element 8c4.

以上のように構成された本実施の形態における自走式掃除機50について、以下その動作、作用について説明する。自走式掃除機50は、自動掃除プログラムの実行により、以下の様に動作する。 The operation and operation of the self-propelled vacuum cleaner 50 according to the present embodiment configured as described above will be described below. The self-propelled vacuum cleaner 50 operates as follows by executing the automatic cleaning program.

まず、掃除の手順の概要を示す。自走式掃除機50は使用者が操作装置17のうちスタートボタン(図示せず)を押すことによって掃除を開始する。あるいは、タイマー設定されている場合には、あらかじめ設定された時刻になると、掃除を開始する。 First, the outline of the cleaning procedure is shown. The self-propelled vacuum cleaner 50 starts cleaning when the user presses a start button (not shown) in the operating device 17. Alternatively, if a timer is set, cleaning is started at a preset time.

充電台(図示せず)から出発した自走式掃除機50は自律移動を開始するとともに、旋回清掃装置2および吸引ファン5とを動作させ、所定のプログラムに応じた経路に沿って移動しながら、部屋の掃除を行っていく。掃除が完了したと判断すれば、制御装置10は吸引ファン5と旋回清掃装置2とを停止して、充電台(図示せず)に向かって移動する。さらに、充電台に接続して充電を開始した時点で運転を停止し、掃除行動を完了する。 The self-propelled vacuum cleaner 50, which departs from the charging stand (not shown), starts autonomous movement, operates the swivel cleaning device 2 and the suction fan 5, and moves along a path according to a predetermined program. , Clean the room. If it is determined that the cleaning is completed, the control device 10 stops the suction fan 5 and the swivel cleaning device 2 and moves toward the charging stand (not shown). Furthermore, when it is connected to the charging stand and charging is started, the operation is stopped and the cleaning action is completed.

狭所判定センサ8が障害物を検出したときは、制御装置10は駆動輪9を制御して自走式掃除機50の前進を中止し、基本的に反時計回りに方向転換し、障害物に接触しないよう進む。そのため、壁に沿って進行中の掃除機本体1は、基本的に右側を壁や家具などの障害物と近接して移動する。 When the narrow space determination sensor 8 detects an obstacle, the control device 10 controls the drive wheels 9 to stop the self-propelled vacuum cleaner 50 from advancing, basically turning counterclockwise, and the obstacle. Proceed so as not to touch. Therefore, the vacuum cleaner main body 1 that is in progress along the wall basically moves on the right side in close proximity to obstacles such as walls and furniture.

また、掃除機本体1の側面に設けられた側方センサ(図示せず)が障害物を検出したときは、制御装置10は回転ブラシ13を駆動させて、障害物のごく近くのゴミを進行方向である矢印Aの方向に弾き飛ばす。これにより、壁や障害物のごく近傍のゴミを掃除することができる。また、壁と家具との隙間を掃除するためには、多くの場合に壁と近接する掃除機本体1の右側にアーム6が存在する方が掃除が容易であるため、本実施の形態ではアーム6は掃除機本体1の右端に設けられている。 Further, when the side sensor (not shown) provided on the side surface of the vacuum cleaner main body 1 detects an obstacle, the control device 10 drives the rotating brush 13 to advance dust in the immediate vicinity of the obstacle. Flick in the direction of arrow A, which is the direction. This makes it possible to clean dust in the immediate vicinity of walls and obstacles. Further, in order to clean the gap between the wall and the furniture, it is easier to clean the arm 6 on the right side of the vacuum cleaner main body 1 which is close to the wall in many cases. Therefore, in the present embodiment, the arm is used. Reference numeral 6 is provided at the right end of the vacuum cleaner main body 1.

図3(a)および(b)を用いて、部屋の隅の壁と家具との隙間に向かって、自走式掃除機50が壁際を進んでいく場合について説明する。この隙間Dは掃除機本体1が入り込むことができないが、アーム6は入り込むことが可能な幅となっている。このような空間に進入した自走式掃除機50において、左側の狭所判定センサ8である素子群8aおよび
素子群8b、素子群8cは、各々の群における全ての高さの素子において障害物を検知している。一方、右の2列の素子群8dおよび素子群8eは障害物を検知していない。
A case where the self-propelled vacuum cleaner 50 advances toward the wall toward the gap between the wall and the furniture in the corner of the room will be described with reference to FIGS. 3 (a) and 3 (b). The vacuum cleaner body 1 cannot enter the gap D, but the arm 6 has a width that allows it to enter. In the self-propelled vacuum cleaner 50 that has entered such a space, the element group 8a, the element group 8b, and the element group 8c, which are the narrow space determination sensors 8 on the left side, are obstacles in the elements at all heights in each group. Is detected. On the other hand, the element group 8d and the element group 8e in the right two rows have not detected an obstacle.

制御装置10は狭所判定センサ8のいずれか一つの素子が障害物を検出すれば、掃除機本体1をそれ以上前進することはない。しかし、アーム6側の2列の素子群8dおよび素子群8eが障害物を検出しない場合は、図3(b)に示すようにアーム6を前進させる。アーム6側の2列の素子群8dおよび素子群8eが検出した奥行に応じて、制御装置10はアーム6の前進距離を決定し、アーム6が壁Bに接触しない範囲でアーム6を前進させる。 If any one element of the narrow space determination sensor 8 detects an obstacle, the control device 10 does not advance the vacuum cleaner main body 1 any further. However, when the two rows of element groups 8d and element group 8e on the arm 6 side do not detect an obstacle, the arm 6 is advanced as shown in FIG. 3 (b). The control device 10 determines the forward distance of the arm 6 according to the depth detected by the two rows of element groups 8d and the element group 8e on the arm 6 side, and advances the arm 6 within a range in which the arm 6 does not contact the wall B. ..

このとき、吸引ファン5は動作しているので、吸引口6aから床面に落ちているゴミを吸い込み始める。図3(a)に示すような隙間Dにおいて、制御装置10は、アーム6を徐々に引き戻すことで、壁Bや家具Cの際のゴミも吸引し、隙間D全体を掃除できる。 At this time, since the suction fan 5 is operating, it starts sucking the dust that has fallen on the floor surface from the suction port 6a. In the gap D as shown in FIG. 3A, the control device 10 can suck dust from the wall B and furniture C by gradually pulling back the arm 6, and can clean the entire gap D.

図6は、壁Bと家具Eとの間により広い幅の隙間Fがある場合を示している。アーム6および掃除機本体1の進退と、掃除機本体1の回転とにより、このような広い幅の隙間に対しても掃除が可能である。隙間Fに対して、中央の素子群8cおよび右側の2列の素子群8dおよび素子群8eは障害物を検知しないが、左側の素子群8aおよび素子群8bは障害物(家具)を検知している。このような場合、制御装置10は、掃除機本体1を前進させずに、アーム6を前進させる。隙間Dの場合と同じく、中央の素子群8cや右側の列の素子群8dおよび素子群8eで検出した障害物までの距離に応じて、アーム6を前進させる。 FIG. 6 shows a case where there is a wider gap F between the wall B and the furniture E. By advancing and retreating the arm 6 and the vacuum cleaner main body 1 and rotating the vacuum cleaner main body 1, it is possible to clean even such a wide gap. With respect to the gap F, the central element group 8c and the two rows of element groups 8d and 8e on the right side do not detect obstacles, but the element group 8a and element group 8b on the left side detect obstacles (furniture). ing. In such a case, the control device 10 advances the arm 6 without advancing the vacuum cleaner main body 1. As in the case of the gap D, the arm 6 is advanced according to the distance to the obstacle detected by the element group 8c in the center, the element group 8d in the right row, and the element group 8e.

その後、制御装置10は、掃除機本体1を一定程度後退させた後、アーム6を前進させた状態のまま反時計回りに回転させる(図6(b)に示す)。このとき、制御装置10は、アーム6の前進直前の状態(図6(a))の中央の素子群8cの前方延長線Gを超えて左側に行かないように、回転角度Hを計算して制限している。 After that, the control device 10 retracts the vacuum cleaner main body 1 to a certain extent, and then rotates the arm 6 counterclockwise while advancing the arm 6 (shown in FIG. 6B). At this time, the control device 10 calculates the rotation angle H so as not to go to the left side beyond the front extension line G of the central element group 8c in the state immediately before the advance of the arm 6 (FIG. 6A). It is restricted.

その後、制御装置10は、元の掃除機本体1の位置まで時計回りに回転させ、アーム6を一定距離後退させた後、再び反時計回りに掃除機本体1を回転させる。このときの回転角度も延長線Gを超えないように決めるので、前回の回転角度Hよりも大きな角度となる。その後、制御装置10は、再び掃除機本体1の元の位置まで時計回りに掃除機本体1を回転させる。 After that, the control device 10 rotates the vacuum cleaner body 1 clockwise to the original position of the vacuum cleaner body 1, retracts the arm 6 by a certain distance, and then rotates the vacuum cleaner body 1 counterclockwise again. Since the rotation angle at this time is also determined so as not to exceed the extension line G, the rotation angle is larger than the previous rotation angle H. After that, the control device 10 rotates the vacuum cleaner main body 1 clockwise again to the original position of the vacuum cleaner main body 1.

掃除機本体1を回転させる際の回転速度は、アーム6の前進距離と関連して決定される。具体的には、制御装置10は、アーム6の前進距離が長いほど、回転速度が遅くなるようにあらかじめ決められている。これによりアーム6の先端部の隙間Fの奥行に応じて、制御装置10はこれらの回転移動を繰り返すことで、隙間Fのような広い幅の隙間に対しても掃除が可能である。アーム6を回転させて掃除するので、アーム6が壁Bと隙間Kが生じてしまう場合も生じる。このような場合は、アーム6が十分壁Bの近傍にまで届くような位置に掃除機本体1を移動させた後、再び上記のような回転移動を伴う動きで掃除すると、隅々まで掃除できる。 The rotation speed at which the vacuum cleaner main body 1 is rotated is determined in relation to the advancing distance of the arm 6. Specifically, the control device 10 is predetermined so that the longer the forward distance of the arm 6, the slower the rotation speed. As a result, the control device 10 can clean a wide gap such as the gap F by repeating these rotational movements according to the depth of the gap F at the tip of the arm 6. Since the arm 6 is rotated for cleaning, the arm 6 may have a gap K with the wall B. In such a case, if the vacuum cleaner main body 1 is moved to a position where the arm 6 can sufficiently reach the vicinity of the wall B, and then the vacuum cleaner body 1 is cleaned again by the movement accompanied by the rotational movement as described above, every corner can be cleaned. ..

また、アーム6は、掃除機本体1が入り込めないような低い隙間にも入り込んで、掃除をすることが可能である。図示しないTV台の下やキッチンラックの下等、床面と家具の底面との間に隙間を有する家具が存在する。 Further, the arm 6 can be cleaned by entering into a low gap where the vacuum cleaner main body 1 cannot enter. There is furniture with a gap between the floor surface and the bottom surface of the furniture, such as under a TV stand or a kitchen rack (not shown).

図7には、そのような家具の例として家具Lを示している。家具Lは掃除機本体1よりも低い位置にあるため、掃除機本体1は入り込めないが、アーム6は掃除機本体1の半分程度の高さしかないため、入り込むことができる。このような状況では、素子8c2およ
び素子8c3、素子8c4は障害物がないと検出するが、素子8c1は障害物があると検出する。このような場合、制御装置10は、掃除機本体1を前進させず、アーム6を前進させる。これにより、低い位置にある隙間でも掃除が可能になる。この家具Lの下の空間が幅方向に広い空間を有していれば、上記で説明したような回転移動を加えた方法で掃除作業を行う。
FIG. 7 shows furniture L as an example of such furniture. Since the furniture L is located lower than the vacuum cleaner main body 1, the vacuum cleaner main body 1 cannot be inserted, but the arm 6 is only about half the height of the vacuum cleaner main body 1 so that it can be inserted. In such a situation, the element 8c2, the element 8c3, and the element 8c4 detect that there is no obstacle, but the element 8c1 detects that there is an obstacle. In such a case, the control device 10 does not advance the vacuum cleaner main body 1 but advances the arm 6. This makes it possible to clean even a gap at a low position. If the space under the furniture L has a wide space in the width direction, the cleaning work is performed by a method in which rotational movement as described above is added.

図2(a)および(b)に示すように、平面視においてアーム6は、駆動輪30の一対の車輪で囲まれた領域よりも外側に配置されている。これにより、駆動輪に影響されることなく、図7に示すようにアームを低い位置に配置できる。そのため、床面と家具の底面との間のような、低い位置にある隙間でも掃除が可能になる。また、掃除機本体1を、高さ方向にコンパクトな構成とすることができ、使い勝手を向上できる。 As shown in FIGS. 2A and 2B, the arm 6 is arranged outside the region surrounded by the pair of wheels of the drive wheels 30 in a plan view. As a result, the arm can be arranged at a low position as shown in FIG. 7 without being affected by the drive wheels. Therefore, it is possible to clean even a gap at a low position such as between the floor surface and the bottom surface of furniture. Further, the vacuum cleaner main body 1 can be made compact in the height direction, and the usability can be improved.

以上のように、本実施の形態における自走式掃除機50は、掃除機本体1の進行方向に向かって右側の略端部にアーム6を設けることによって、壁と家具との間の掃除機本体1が入り込めない隙間の部分でも掃除が可能になる。これにより、自走式掃除機50の掃除残しの部分を大幅に低減することができるので、使用者が自ら掃除する手間を大幅に低減して使い勝手を向上させた自走式掃除機を提供することが可能となる。 As described above, the self-propelled vacuum cleaner 50 according to the present embodiment is a vacuum cleaner between a wall and furniture by providing an arm 6 at a substantially right end portion on the right side in the traveling direction of the vacuum cleaner main body 1. Cleaning is possible even in the gaps where the main body 1 cannot enter. As a result, the uncleaned portion of the self-propelled vacuum cleaner 50 can be significantly reduced, so that the self-propelled vacuum cleaner is provided with improved usability by significantly reducing the time and effort for the user to clean by himself / herself. It becomes possible.

また、掃除機本体1の側方に沿ってアーム6が屈曲して収納される構成としたことにより、掃除機本体1の後部を略円形状にすることが可能となる。その結果、掃除機本体1の方向を転換する際に邪魔になる円形からの飛び出し部分がなく、狭い場所でもスムーズに方向転換して狭い空間から脱出する可能性を大幅に高めることができる。 Further, since the arm 6 is bent and stored along the side of the vacuum cleaner main body 1, the rear portion of the vacuum cleaner main body 1 can be formed into a substantially circular shape. As a result, there is no protruding portion from the circle that becomes an obstacle when changing the direction of the vacuum cleaner main body 1, and it is possible to greatly increase the possibility of smoothly changing the direction and escaping from the narrow space even in a narrow place.

これにより、途中で掃除を中断してしまうようなことがない信頼性の高い自走式掃除機50を提供することが可能となる。また、アーム6が掃除機本体1の側方に沿って曲がるように収納されるので、掃除機本体1の前後方向の長さを短くできる。これにより、掃除機本体1をコンパクトに構成でき、使い勝手を向上できる。 This makes it possible to provide a highly reliable self-propelled vacuum cleaner 50 that does not interrupt cleaning on the way. Further, since the arm 6 is housed so as to bend along the side of the vacuum cleaner main body 1, the length of the vacuum cleaner main body 1 in the front-rear direction can be shortened. As a result, the vacuum cleaner main body 1 can be configured compactly, and usability can be improved.

また、アーム6は、複数の集塵口6eを有しているので、アーム6を全て前進させるのでなく、中間位置まで前進させるだけでもゴミを吸引することができる。そのため、掃除機本体1の位置を調整できないような狭い空間の場合でも、アーム6の前進距離を調整することでその空間に応じた掃除が可能になる。これにより、より狭い空間でも掃除性を向上できる自走式掃除機50を提供することが可能となる。 Further, since the arm 6 has a plurality of dust collecting ports 6e, dust can be sucked only by advancing the arm 6 to an intermediate position instead of advancing all the arms 6. Therefore, even in a narrow space where the position of the vacuum cleaner main body 1 cannot be adjusted, it is possible to perform cleaning according to the space by adjusting the advancing distance of the arm 6. This makes it possible to provide a self-propelled vacuum cleaner 50 that can improve cleanability even in a narrower space.

また、図8に示すようにアーム6の先端経路6cの先端部に近接センサ21を設けることにより、アーム6と壁との距離をより正確に検出することができる。これにより、狭所判定センサ8で正確に距離を検出できない場合でも、アーム6を壁にぶつけてしまうことがなく、家具や壁を傷つけない自走式掃除機50を提供することができる。なお、近接センサ21を、側面側にも設けておくと、アーム6の前方向の障害物を検知するだけでなく、側面方向の障害物をも検知できるため、壁や家具にアーム6をよりぶつかりにくくできる。 Further, as shown in FIG. 8, by providing the proximity sensor 21 at the tip of the tip path 6c of the arm 6, the distance between the arm 6 and the wall can be detected more accurately. As a result, it is possible to provide the self-propelled vacuum cleaner 50 that does not hit the arm 6 against the wall and does not damage the furniture or the wall even when the narrow space determination sensor 8 cannot accurately detect the distance. If the proximity sensor 21 is also provided on the side surface side, not only the obstacle in the front direction of the arm 6 can be detected, but also the obstacle in the side surface direction can be detected. You can make it harder to hit.

なお、本実施の形態においては、アーム6は掃除機本体1の右端に設けられているが、障害物回避の方法を時計回りにして、掃除機本体1の左端にアーム6を取り付けてもよい。 In the present embodiment, the arm 6 is provided at the right end of the vacuum cleaner main body 1, but the arm 6 may be attached to the left end of the vacuum cleaner main body 1 by turning the obstacle avoidance method clockwise. ..

なお、本実施の形態において、狭所判定センサは4×5の格子状に素子を配置しているが、もっと多量の素子を用いて、さらに詳しく狭所の判定を行っても良い。また、カメラを用いて撮影した画像から狭所の形状や距離を算出したり、TOF(Time−of−Flight)センサを用いるなど、狭所の判定を行える他のセンサを用いてもよい。 In the present embodiment, the narrow space determination sensor arranges the elements in a 4 × 5 grid pattern, but a larger number of elements may be used to determine the narrow space in more detail. Further, another sensor capable of determining the narrow space may be used, such as calculating the shape and distance of the narrow space from the image taken by the camera, or using a TOF (Time-of-Flight) sensor.

なお、本実施の形態において、アーム6が突出位置にある際の掃除機本体1からのアーム6の突出長さは、掃除機本体1の前後寸法の約半分程度である。しかしながら、さらに長く突出させることにより、例えばTV台の奥など人が掃除しにくい部分も掃除しやすくできる。これにより、さらに使い勝手を向上できる。 In the present embodiment, the protruding length of the arm 6 from the vacuum cleaner main body 1 when the arm 6 is in the protruding position is about half of the front-rear dimension of the vacuum cleaner main body 1. However, by projecting it longer, it is possible to easily clean a part that is difficult for a person to clean, such as the back of a TV stand. As a result, usability can be further improved.

以上のように、本発明にかかる自走式掃除機は、壁の近くに家具等障害物がある場合でも、壁と家具との隙間の掃除が可能になるので、掃除ロボット以外にも、片付けロボットなど他のアームを有する機器の用途にも適用できる。 As described above, the self-propelled vacuum cleaner according to the present invention can clean the gap between the wall and the furniture even if there is an obstacle such as furniture near the wall. It can also be applied to devices with other arms such as robots.
