しかしながら、この公報のものは、自律走行掃除用の吸込み口体を手動操作掃除用のホース体に取り付けることはできず、ホース体はその延長管部の先端に独自の吸込み口部を取り付ける構成になっていた。すなわち、自律走行掃除と手動操作掃除とで異なる構成の吸込み口体を用意しなければならず、部品点数が増加するとともに経済性も悪いという問題があった。   However, in this publication, the suction port body for autonomous traveling cleaning cannot be attached to the hose body for manual operation cleaning, and the hose body has a configuration in which an original suction port portion is attached to the tip of the extension pipe portion.

A dust collecting mechanism 9 having The dust collection method includes a paper pack method and a cyclone method, and any method may be used here. Moreover, the cleaner body 1 is equipped with a battery 10 that is a secondary battery that supplies power to each part.

掃除機本体1の前部に、集塵機構9の集塵室7に吸気を導くための接続管11を設けている。接続管11は中央部を曲折し、その曲折部11aを掃除機本体1の前部上端に支持するとともに一端を集塵室7に連通している。接続管11の両端は開口端になっている。そして、接続管11は曲折部11aを支点として他端が、下方に向く位置から上方に向かって回動自在になっている。その結果、接続管11の他端は、下方に向く状態と前方に向く状態とに選択可能となっている。   A connecting pipe 11 for guiding the intake air to the dust collection chamber 7 of the dust collection mechanism 9 is provided at the front of the cleaner body 1. The connecting pipe 11 is bent at the center, the bent portion 11 a is supported on the front upper end of the cleaner body 1, and one end is communicated with the dust collection chamber 7. Both ends of the connecting pipe 11 are open ends. The connecting pipe 11 is pivotable upward from a position facing the lower end with the bent portion 11a as a fulcrum. As a result, the other end of the connecting pipe 11 can be selected between a downward direction and a forward direction.

掃除機本体1は、自律走行して掃除を行うときには、図1に示すように、接続管11の他端に床面掃除用ノズル機構12の連通管13を接続して両者を連通させ、接続管11をその他端が下方に向くように後述する固定機構により掃除機本体1に位置決めして床面掃除用ノズル機構12を床面上に配置するようにしている。   As shown in FIG. 1, the cleaner body 1 is connected to the other end of the connection pipe 11 by connecting the communication pipe 13 of the floor surface cleaning nozzle mechanism 12 to allow both to communicate with each other. The pipe 11 is positioned on the cleaner body 1 by a fixing mechanism which will be described later so that the other end faces downward, and the floor cleaning nozzle mechanism 12 is arranged on the floor.

床面掃除用ノズル機構12は、底部他端側に床面から塵埃を吸引するノズル部14aが形成されたノズル本体14と、このノズル本体14の上部一端側に上下方向に回動自在に設けられた連通管13とを備えている。ノズル部14aには、回転清掃体15が配置され、この回転清掃体15はノズル本体14内に設けられた直流ブラシモータ16で回転駆動される。床面掃除用ノズル機構12は、連通管13が設けられた一端側底部に、ノズル本体14の外周から突出するとともに突出した端部が床面から徐々に高くなるように曲がった翼形状の部材17を取り付けている。   The nozzle mechanism 12 for cleaning the floor surface is provided with a nozzle body 14 having a nozzle portion 14a for sucking dust from the floor surface on the other end side of the bottom, and an upper end side of the nozzle body 14 so as to be rotatable in the vertical direction. The communication pipe 13 is provided. A rotary cleaning body 15 is disposed in the nozzle portion 14 a, and the rotary cleaning body 15 is rotationally driven by a DC brush motor 16 provided in the nozzle body 14. The floor cleaning nozzle mechanism 12 is a wing-shaped member that protrudes from the outer periphery of the nozzle body 14 at the one end side where the communication pipe 13 is provided and is bent so that the protruding end gradually becomes higher from the floor surface. 17 is attached.

床面掃除用ノズル機構12は、自律走行して掃除を行うときには、図1に示すように、ノズル本体14の一端側に設けられた連通管13が進行方向前側に位置し、前記ノズル部14aが進行方向後側に位置するようにして連通管13を接続管11に取り付ける。   When the floor cleaning nozzle mechanism 12 performs autonomous cleaning to perform cleaning, as shown in FIG. 1, the communication pipe 13 provided on one end side of the nozzle body 14 is located on the front side in the traveling direction, and the nozzle portion 14a. The communication pipe 13 is attached to the connection pipe 11 so that is positioned on the rear side in the traveling direction.

掃除機本体1は、図3に示すように、自律走行による掃除を行う場合に使用される複数の障害物検知センサ18を前部に配置している。また、掃除機本体1には、接続管11または床面掃除用ノズル機構12を掃除機本体1に形成した溝19内に固定することにより、接続管11の他端部が下方を向いた状態に固定する固定機構20を設けている。固定機構20は帯状部材20aをスライドするスライド式のもので、帯状部材20aの一端に設けたつまみ20bをスライド溝20cに沿って左右にスライド操作することで帯状部材20aを左右にスライドするようになっている。図3に示す固定状態で、つまみ20bを図中右側にスライド操作したときに帯状部材20aが図中右側にスライドし、溝19が開放されて接続管11と床面掃除用ノズル機構12との固定が解除される。なお、固定機構の構成はこれに限定するものでないのは勿論である。   As shown in FIG. 3, the cleaner body 1 has a plurality of obstacle detection sensors 18 that are used in the case of performing cleaning by autonomous traveling at the front. Further, in the cleaner body 1, the connecting pipe 11 or the floor cleaning nozzle mechanism 12 is fixed in the groove 19 formed in the cleaner body 1 so that the other end of the connecting pipe 11 faces downward. A fixing mechanism 20 is provided for fixing to. The fixing mechanism 20 is a slide type that slides the belt-like member 20a. By sliding the knob 20b provided at one end of the belt-like member 20a to the left and right along the slide groove 20c, the belt-like member 20a is slid to the left and right. It has become. When the knob 20b is slid to the right side in the figure in the fixed state shown in FIG. 3, the belt-like member 20a slides to the right side in the figure, the groove 19 is opened, and the connection pipe 11 and the floor cleaning nozzle mechanism 12 Fixing is released. Of course, the configuration of the fixing mechanism is not limited to this.

前記駆動力伝達手段は、減速機構5a、5bのほか、この減速機構5a、5b内に設けた駆動力の伝達を断続させるクラッチ21と、スプリング等の弾性部材22を備えている。さらに、駆動力伝達手段は、接続管11と床面掃除用ノズル機構12とを固定機構20によって固定した状態では弾性部材22の弾性力に抗して押し込まれ、固定機構20による固定を解除したときには弾性部材22の弾性力によって前方へ突出する突出部23と、この突出部23の進退動作をクラッチ21に伝達し、突出部23が押し込まれたときにはクラッチ21を駆動力の伝達が可能な状態にし、突出部23が突出したときにはクラッチ21の駆動力伝達可能な状態を解除する連結部材24と、この連結部材24の動作に応動し、突出部23が押し込まれたときには左右の車輪駆動用モータ4a、4bへの通電路を閉成し、突出部23が突出したときには前記左右の車輪駆動用モータ4a、4bへの通電路を開放する動作を行うスイッチ機構25とを備えている。   In addition to the speed reduction mechanisms 5a and 5b, the driving force transmission means includes a clutch 21 provided in the speed reduction mechanisms 5a and 5b, which interrupts transmission of the driving force, and an elastic member 22 such as a spring. Further, the driving force transmission means is pushed against the elastic force of the elastic member 22 in a state where the connecting pipe 11 and the floor cleaning nozzle mechanism 12 are fixed by the fixing mechanism 20, and the fixing by the fixing mechanism 20 is released. Sometimes, the projecting portion 23 projecting forward by the elastic force of the elastic member 22 and the forward / backward movement of the projecting portion 23 are transmitted to the clutch 21. When the projecting portion 23 is pushed, the clutch 21 can transmit the driving force. When the projecting portion 23 projects, the connecting member 24 releases the state in which the driving force of the clutch 21 can be transmitted, and the left and right wheel driving motors respond to the operation of the connecting member 24 and when the projecting portion 23 is pushed in. 4a and 4b are closed, and when the protruding portion 23 protrudes, the switch for performing the operation of opening the right and left wheel drive motors 4a and 4b is opened. And a mechanism 25.

なお、クラッチ21は、減速機構5a、5bのアイドラを変位させる方式のクラッチでも、円盤を押し付ける方式のクラッチでも、あるいはスプリングクラッチであってもよい。また、スイッチ機構25はスイッチ単体であってもスイッチとリレーによって構成されるものであってもよい。   The clutch 21 may be a clutch that displaces idlers of the speed reduction mechanisms 5a and 5b, a clutch that presses a disk, or a spring clutch. Further, the switch mechanism 25 may be a single switch or a switch and a relay.

掃除機本体1は、手動操作によって掃除を行うときには、固定機構20のつまみ20bを図3中右側にスライド操作して溝19を開放状態にする。また、手動操作用管機構26を用意する。手動操作用管機構26は、一端に接続管11の他端と着脱可能な連通部27を有するとともに他端に操作管30を有するホース28と、ホース28の操作管30に着脱可能な棒状の延長管29とからなっている。ホース28は連通部27と操作管30を除く部分は柔軟性を有している。一端が操作管30に接続される延長管29の他端は、接続管11の他端と同様に、床面掃除用ノズル機構12の連通管13が着脱可能に接続できる形状に形成されている。そして、使用者は、掃除機本体1に手動操作用管機構26を接続し、手動操作用管機構26に床面掃除用ノズル機構12を接続して図2に示す状態とすることにより、手動操作による掃除を行うことができる。   When the vacuum cleaner main body 1 performs cleaning by manual operation, the knob 20b of the fixing mechanism 20 is slid to the right side in FIG. In addition, a manual operation pipe mechanism 26 is prepared. The manual operation pipe mechanism 26 includes a hose 28 having a communication portion 27 that can be attached to and detached from the other end of the connection pipe 11 at one end and an operation pipe 30 at the other end, and a rod-like shape that can be attached to and detached from the operation pipe 30 of the hose 28. It consists of an extension tube 29. The portion of the hose 28 excluding the communication portion 27 and the operation tube 30 has flexibility. The other end of the extension pipe 29 whose one end is connected to the operation pipe 30 is formed in a shape that allows the communication pipe 13 of the floor cleaning nozzle mechanism 12 to be detachably connected, similarly to the other end of the connection pipe 11. . Then, the user connects the manual operation pipe mechanism 26 to the vacuum cleaner body 1 and connects the floor cleaning nozzle mechanism 12 to the manual operation pipe mechanism 26 to obtain the state shown in FIG. Cleaning by operation can be performed.

手動操作による掃除を行う場合、床面掃除用ノズル機構12の連通管13を、自律走行によって掃除を行うときとは前後逆向きにして延長管29に取り付けている。すなわち、床面掃除用ノズル機構12は、そのノズル部14aが前側に位置し、翼形状の部材17が後側に位置するようにして延長管29の先端に取り付けている。   When performing cleaning by manual operation, the communication pipe 13 of the floor surface cleaning nozzle mechanism 12 is attached to the extension pipe 29 in a direction opposite to the front and rear direction when cleaning is performed by autonomous traveling. That is, the floor surface cleaning nozzle mechanism 12 is attached to the distal end of the extension pipe 29 such that the nozzle portion 14a is positioned on the front side and the wing-shaped member 17 is positioned on the rear side.

接続管11、手動操作用管機構26、床面掃除用ノズル機構12のそれぞれの管内には掃除機本体1からの直流電力を直流ブラシモータ16に供給する電力供給線が配線されており、接続管11に床面掃除用ノズル機構12を直接取り付けたときには、図4の(a)に示すように途中で極性が反転することなく電力供給線が直流ブラシモータ16に接続される。これに対し、接続管11に手動操作用管機構26を取り付け、この手動操作用管機構26に床面掃除用ノズル機構12を取り付けたときには図4の(b)に示すように手動操作用管機構26内で極性が反転されて電力供給線が直流ブラシモータ16に接続される。従って、自律走行によって掃除を行うときと手動操作によって掃除を行うときとで直流ブラシモータ16の回転方向が異なることになる。   A power supply line for supplying DC power from the cleaner body 1 to the DC brush motor 16 is wired in each of the connection pipe 11, the manual operation pipe mechanism 26, and the floor cleaning nozzle mechanism 12. When the floor cleaning nozzle mechanism 12 is directly attached to the tube 11, the power supply line is connected to the DC brush motor 16 without reversing the polarity in the middle as shown in FIG. On the other hand, when the manual operation pipe mechanism 26 is attached to the connecting pipe 11 and the floor cleaning nozzle mechanism 12 is attached to the manual operation pipe mechanism 26, as shown in FIG. The polarity is reversed in the mechanism 26 and the power supply line is connected to the DC brush motor 16. Therefore, the direction of rotation of the DC brush motor 16 is different when cleaning is performed by autonomous traveling and when cleaning is performed by manual operation.

図5は前記掃除機本体1に設けた制御部の構成を示すブロック図で、制御部本体を構成するCPU(中央処理装置)31、このCPU31が各部を制御するためのプログラムデータを格納したROM(リード・オンリー・メモリ)32、CPU31が演算やデータ処理等に使用するメモリを設けたRAM(ランダム・アクセス・メモリ)33及び入出力ポート34を設け、これらをバスライン35によって電気的に接続している。   FIG. 5 is a block diagram showing the configuration of the control unit provided in the cleaner body 1. A CPU (central processing unit) 31 constituting the control unit body and a ROM storing program data for the CPU 31 to control each unit. (Read Only Memory) 32, a RAM (Random Access Memory) 33 provided with a memory used by the CPU 31 for operations and data processing, and an input / output port 34 are provided, and these are electrically connected by a bus line 35. is doing.

入出力ポート34に、障害物検知センサ18、吸気用ファンモータ6を駆動するモータ駆動部36、左車輪駆動用モータ4aを駆動するモータ駆動部37、右車輪駆動用モータ4bを駆動するモータ駆動部38、前記左駆動車輪2aの回転を検知する左車輪エンコーダ39、右駆動車輪2bの回転を検知する右車輪エンコーダ40及び床面掃除用ノズル機構12に設けた直流ブラシモータ16を駆動するモータ駆動部41を接続している。バッテリ10はスイッチ機構25を介して左右の車輪駆動用モータ4a、4bに電力を供給するとともに各部に対しても電力を供給するようになっている。   The input / output port 34 has an obstacle detection sensor 18, a motor drive unit 36 for driving the intake fan motor 6, a motor drive unit 37 for driving the left wheel drive motor 4a, and a motor drive for driving the right wheel drive motor 4b. Motor for driving the DC brush motor 16 provided on the floor 38, the left wheel encoder 39 for detecting the rotation of the left driving wheel 2a, the right wheel encoder 40 for detecting the rotation of the right driving wheel 2b, and the floor cleaning nozzle mechanism 12. The drive part 41 is connected. The battery 10 supplies electric power to the left and right wheel drive motors 4a and 4b via the switch mechanism 25 and also supplies electric power to each part.

このような構成においては、掃除機本体1に自律走行による掃除を行わせるときには、ノズル部14aが進行方向後側に位置し、翼形状の部材17が進行方向前側に位置するようにして、床面掃除用ノズル機構12の連通部13を接続管11に取り付ける。そして、固定機構20のつまみ20bを操作して溝19を開放し、接続管11と床面掃除用ノズル機構12を溝19内に押し込み、つまみ20bを逆方向に操作して帯状部材20aを戻して固定機構20により、接続管11と床面掃除用ノズル機構12を溝19内に固定する。   In such a configuration, when the cleaner body 1 performs cleaning by autonomous running, the nozzle portion 14a is positioned on the rear side in the traveling direction, and the wing-shaped member 17 is positioned on the front side in the traveling direction, The communicating portion 13 of the surface cleaning nozzle mechanism 12 is attached to the connecting pipe 11. Then, the knob 20b of the fixing mechanism 20 is operated to open the groove 19, the connecting pipe 11 and the floor cleaning nozzle mechanism 12 are pushed into the groove 19, and the knob 20b is operated in the reverse direction to return the belt-like member 20a. The fixing mechanism 20 fixes the connecting pipe 11 and the floor cleaning nozzle mechanism 12 in the groove 19.

これにより、駆動力伝達手段の突出部23が弾性部材22の弾性力に抗して押し込まれ、連結部材24はクラッチ21を駆動力の伝達が可能な状態に動作する。また、連結部材24はスイッチ機構25を左右の車輪駆動用モータ4a、4bへの通電路を閉成するように動作する。   As a result, the projecting portion 23 of the driving force transmitting means is pushed against the elastic force of the elastic member 22, and the connecting member 24 operates so that the clutch 21 can transmit the driving force. The connecting member 24 operates so that the switch mechanism 25 closes the energization path to the left and right wheel driving motors 4a and 4b.

従って、この状態では左右の車輪駆動用モータ4a、4bは動作可能な状態になり、掃除機本体1に設けられた図示しない自律走行用スイッチをオンすることにより、CPU31がプログラムデータに基づいて各モータ駆動部37、38を制御することで左右の車輪駆動用モータ4a、4bが回転動作し、それにより、左右の駆動車輪2a、2bが回転動作し、掃除機本体1は自律走行する。そして、各駆動車輪2a、2bの回転がそれぞれエンコーダ39、40によって検出され、CPU31によって掃除機本体1の走行距離や走行速度や走行方向等が算出される。また、前方に障害物があれば障害物検知センサ18によって検知され、CPU31によって障害物までの距離が算出される。こうして、掃除機本体1は自律走行時の前進、後退、方向転換の各制御が行われる。   Therefore, in this state, the left and right wheel drive motors 4a, 4b are in an operable state, and the CPU 31 is turned on based on the program data by turning on an autonomous travel switch (not shown) provided in the cleaner body 1. The left and right wheel drive motors 4a and 4b rotate by controlling the motor drive units 37 and 38, whereby the left and right drive wheels 2a and 2b rotate and the cleaner body 1 travels autonomously. Then, the rotations of the drive wheels 2a and 2b are respectively detected by the encoders 39 and 40, and the CPU 31 calculates the travel distance, travel speed, travel direction, and the like of the cleaner body 1. If there is an obstacle ahead, the obstacle detection sensor 18 detects the obstacle, and the CPU 31 calculates the distance to the obstacle. Thus, the vacuum cleaner main body 1 performs forward, backward, and turn control during autonomous traveling.

また、CPU31がモータ駆動部36を制御することで吸気用ファンモータ6が回転し、床面掃除用ノズル機構12のノズル部14aから連通管13、接続管11を介して吸気が行われる。また、CPU31がモータ駆動部41を制御することでブラシモータ16が回転し回転清掃体15が回転する。回転清掃体15は、例えば図1において反時計方向に回転する。   The CPU 31 controls the motor drive unit 36 to rotate the intake fan motor 6, and intake is performed from the nozzle portion 14 a of the floor surface cleaning nozzle mechanism 12 through the communication pipe 13 and the connection pipe 11. Further, when the CPU 31 controls the motor driving unit 41, the brush motor 16 rotates and the rotary cleaning body 15 rotates. For example, the rotary cleaning body 15 rotates counterclockwise in FIG.

こうして、回転清掃体15の回転や吸込風によって床面から塵埃がノズル部14aに取り込まれ、取り込まれた塵埃は空気と共に集塵室7に集められる。塵埃を含んだ吸込風はフィルタ8で濾過され、塵埃は集塵室7に溜められる一方、塵埃と分離された空気はファンモータ6を介して外部に放出される。また、回転清掃体15は、掃除機本体1の進行方向に対して順方向に回転するので、掃除機本体1の走行が補助される。   Thus, the dust is taken into the nozzle portion 14a from the floor surface by the rotation of the rotary cleaning body 15 and the suction air, and the taken-in dust is collected in the dust collecting chamber 7 together with the air. The suction air containing dust is filtered by the filter 8, and the dust is collected in the dust collection chamber 7, while the air separated from the dust is discharged to the outside through the fan motor 6. Moreover, since the rotary cleaning body 15 rotates in the forward direction with respect to the traveling direction of the cleaner body 1, traveling of the cleaner body 1 is assisted.

次に、この掃除機本体1で手動操作による掃除を行うときには、固定機構20のつまみ20bを操作して接続管11と掃除機本体1との固定状態を解除する。そして、接続管11の他端が前方に向くように接続管11を回動し、接続管11から床面掃除用ノズル機構12を離脱させる。なお、掃除機本体1には図示しないクリック機構等で構成される保持部が設けられており、この保持部によって、接続管11は前方を向いた状態に保持される。   Next, when cleaning is performed manually by the cleaner body 1, the fixing state of the connection pipe 11 and the cleaner body 1 is released by operating the knob 20 b of the fixing mechanism 20. Then, the connecting pipe 11 is rotated so that the other end of the connecting pipe 11 faces forward, and the floor cleaning nozzle mechanism 12 is detached from the connecting pipe 11. In addition, the vacuum cleaner main body 1 is provided with a holding portion configured by a click mechanism or the like (not shown), and the connecting pipe 11 is held in a state of facing forward by the holding portion.

接続管11と床面掃除用ノズル機構12の固定状態が解除、すなわち固定機構20による固定が解除されると、駆動力伝達手段の突出部23が弾性部材22の弾性力によって前方に突出する。これにより、連結部材24はクラッチ21を駆動力の伝達が可能な状態から解除し、以後、左右の駆動用モータ4a、4bの回転駆動力は左右の駆動車輪2a、2bに伝達することができなくなる。すなわち、左右の駆動車輪2a、2bは自由回転できる状態になる。また、スイッチ機構25は左右の車輪駆動用モータ4a、4bへの通電路を開放するように動作する。   When the fixed state of the connecting pipe 11 and the floor cleaning nozzle mechanism 12 is released, that is, when the fixing by the fixing mechanism 20 is released, the protruding portion 23 of the driving force transmitting means protrudes forward by the elastic force of the elastic member 22. As a result, the connecting member 24 releases the clutch 21 from the state in which the driving force can be transmitted, and thereafter, the rotational driving force of the left and right driving motors 4a, 4b can be transmitted to the left and right driving wheels 2a, 2b. Disappear. That is, the left and right drive wheels 2a and 2b can be freely rotated. The switch mechanism 25 operates so as to open the energization path to the left and right wheel drive motors 4a and 4b.

そして、手動操作用管機構26を用意し、この手動操作用管機構26の連通部27を接続管11の他端に取り付ける。また、この手動操作用管機構26の延長管29の先端に接続管11から分離した床面掃除用ノズル機構12の連通管13を取り付ける。このとき、床面掃除用ノズル機構12をそのノズル部14aが進行方向前側に位置し、翼形状の部材17が進行方向後側に位置するようにして取り付ける。   Then, a manual operation pipe mechanism 26 is prepared, and a communication portion 27 of the manual operation pipe mechanism 26 is attached to the other end of the connection pipe 11. Further, the communication pipe 13 of the floor cleaning nozzle mechanism 12 separated from the connection pipe 11 is attached to the tip of the extension pipe 29 of the manual operation pipe mechanism 26. At this time, the floor cleaning nozzle mechanism 12 is mounted such that the nozzle portion 14a is positioned on the front side in the traveling direction and the wing-shaped member 17 is positioned on the rear side in the traveling direction.

この状態では掃除機本体1の走行は手動操作用管機構26を手にもった使用者が手動操作用管機構26を引っ張ることで行われる。また、CPU31がモータ駆動部36を制御することで吸気用ファンモータ6が回転し、床面掃除用ノズル機構12のノズル部14aから連通管13、手動操作用管機構26、接続管11を介して吸気が行われる。また、CPU31がモータ駆動部41を制御することでブラシモータ16が回転し回転清掃体15が回転する。   In this state, the vacuum cleaner body 1 travels when the user holding the manual operation pipe mechanism 26 pulls the manual operation pipe mechanism 26. The CPU 31 controls the motor drive unit 36 to rotate the intake fan motor 6, and the nozzle portion 14 a of the floor cleaning nozzle mechanism 12 passes through the communication pipe 13, the manual operation pipe mechanism 26, and the connection pipe 11. Inhalation is performed. Further, when the CPU 31 controls the motor driving unit 41, the brush motor 16 rotates and the rotary cleaning body 15 rotates.

このときブラシモータ16への電力供給の極性が反転されているので、ブラシモータ16は自律走行時とは逆方向に回転する。しかし、床面掃除用ノズル機構12の取り付けの向きが自律走行時とは逆向きになっているので、回転清掃体15は、図2においてやはり反時計方向に回転する。すなわち、自律走行時と同様に、床面掃除用ノズル機構12の前方への移動に対して順方向に回転する。   At this time, since the polarity of power supply to the brush motor 16 is reversed, the brush motor 16 rotates in the opposite direction to that during autonomous running. However, since the mounting direction of the floor cleaning nozzle mechanism 12 is opposite to that during autonomous running, the rotary cleaning body 15 also rotates counterclockwise in FIG. That is, as in the autonomous running, the floor cleaning nozzle mechanism 12 rotates in the forward direction with respect to the forward movement.

こうして、手動操作による掃除がなされ、自律走行掃除時と同様に、塵埃は集塵室7に溜められる一方、塵埃と分離された空気は外部に放出される。また、回転清掃体15は、床面掃除用ノズル機構12の進行方向に対して順方向に回転するので、床面掃除用ノズル機構12の走行が補助されて操作性が向上される。   In this way, manual cleaning is performed, and dust is stored in the dust collecting chamber 7 while air separated from the dust is discharged to the outside as in the case of autonomous running cleaning. Moreover, since the rotary cleaning body 15 rotates in the forward direction with respect to the traveling direction of the floor surface cleaning nozzle mechanism 12, traveling of the floor surface cleaning nozzle mechanism 12 is assisted to improve operability.

上記実施の形態による電気掃除機によれば、自律走行による掃除時と手動操作による掃除時とで共通の床面掃除用ノズル機構12を用いることができるから、両掃除時個別の床面掃除用ノズル機構を用意する必要がなく、経済性を向上できる。しかも、床面掃除用ノズル機構12または手動操作用管機構26が選択的に取り付けられる接続管11の他端を、下方を向く状態と前方を向く状態とにすることができるので、いずれの掃除時にも好適である。すなわち、接続管11の他端を、自律走行による掃除時には床面掃除用ノズル機構12が位置する下方に向けることができるだけでなく、手動操作による掃除時には床面掃除用ノズル機構12が位置する前方に向けることができる。したがって、特に手動操作による掃除時の操作性を良好とすることができる。   According to the vacuum cleaner according to the above embodiment, the common floor cleaning nozzle mechanism 12 can be used for cleaning by autonomous driving and cleaning by manual operation. There is no need to prepare a nozzle mechanism, and the economy can be improved. In addition, the other end of the connecting pipe 11 to which the floor surface cleaning nozzle mechanism 12 or the manual operation pipe mechanism 26 is selectively attached can be set to a state facing downward and a state facing frontward. Sometimes suitable. That is, not only can the other end of the connecting pipe 11 be directed downward where the floor cleaning nozzle mechanism 12 is positioned during cleaning by autonomous traveling, but also the front where the floor cleaning nozzle mechanism 12 is positioned during cleaning by manual operation. Can be directed to. Therefore, the operability at the time of cleaning especially by manual operation can be improved.

また、自律走行による掃除時に、ノズル部14aとは反対側に位置しノズル本体14に上下回動自在に設けられた連通管13を前側にして、床面掃除用ノズル機構12を掃除機本体1に取り付けたので、以下のような利点を有する。すなわち、上記構成によれば、床面掃除用ノズル機構12は接続管11と連通管13の長さから決まる高さで、その進行方向前方に位置する連通管13とノズル本体14との支点の位置が固定され、ノズル本体14はこの支点を中心に自重で床面に接触する。このとき進行方向前方となる支点位置を数mm床面から離すことにより、ゴミを吸い込むノズル部14aを床面に接触させつつ吸引のための風路を確保することが出来る。しかも、床面掃除用ノズル機構12の後端に位置するノズル本体14が自由に上下可能になっていることにより、床面上の高さの低い障害物があっても、床面掃除用ノズル機構12は引っかかることなくスムーズに移動することができる。加えて、床面掃除用ノズル機構12の底部他端に突出した端部が床面から徐々に高くなるように曲がった翼形状の部材17を取り付けているので、よりスムーズに乗り越えることができる。   Further, during cleaning by autonomous traveling, the floor cleaning nozzle mechanism 12 is placed on the cleaner main body 1 with the communication pipe 13 positioned on the opposite side to the nozzle portion 14a and provided on the nozzle main body 14 so as to be vertically rotatable. Since it is attached to, it has the following advantages. That is, according to the above configuration, the floor cleaning nozzle mechanism 12 has a height determined by the lengths of the connection pipe 11 and the communication pipe 13, and is a fulcrum between the communication pipe 13 and the nozzle body 14 positioned in the forward direction of the travel. The position is fixed, and the nozzle body 14 comes into contact with the floor surface by its own weight around this fulcrum. At this time, by separating the fulcrum position in front of the traveling direction by several mm from the floor surface, it is possible to secure an air passage for suction while bringing the nozzle portion 14a for sucking dust into contact with the floor surface. Moreover, since the nozzle body 14 located at the rear end of the floor cleaning nozzle mechanism 12 can freely move up and down, even if there is an obstacle on the floor surface with a low height, the floor cleaning nozzle The mechanism 12 can move smoothly without being caught. In addition, since the wing-shaped member 17 that is bent so that the end protruding to the other end of the bottom of the floor surface cleaning nozzle mechanism 12 gradually increases from the floor surface is attached, it can be overcome more smoothly.

しかも、連通管13が接続管11に接続された場合と延長管29に接続された場合とで、直流ブラシモータ16の回転方向を異なるものとしているので、自律走行による掃除時にも手動操作による掃除時にも、回転清掃体15を進行方向に対して順方向に回転させることができる。したがって、回転清掃体15の回転により、自律走行による掃除時には掃除機本体1の走行を、手動操作による掃除時には床面掃除用ノズル12の前方への移動操作を、それぞれ補助することができる。ここで重要なことは、掃除機本体1あるいは床面掃除用ノズル機構12の進行方向に対する回転清掃体15の回転方向を、両掃除時に同方向とすることであり、本実施の形態においては、これらの進行方向に対して回転清掃体15を順方向に回転させるようにしたが、両掃除時に床面の塵埃の掻き出し効率を高めることを目的として、逆方向に回転させるようにしてもよい。   Moreover, since the rotation direction of the DC brush motor 16 is different between the case where the communication pipe 13 is connected to the connection pipe 11 and the case where it is connected to the extension pipe 29, the cleaning by the manual operation is also performed at the time of cleaning by autonomous traveling. Sometimes, the rotary cleaning body 15 can be rotated in the forward direction with respect to the traveling direction. Therefore, the rotation of the rotary cleaning body 15 can assist the traveling of the cleaner body 1 during cleaning by autonomous traveling, and the forward movement operation of the floor cleaning nozzle 12 during cleaning by manual operation. What is important here is that the rotational direction of the rotary cleaning body 15 with respect to the traveling direction of the cleaner body 1 or the floor cleaning nozzle mechanism 12 is the same direction during both cleanings. Although the rotary cleaning body 15 is rotated in the forward direction with respect to these traveling directions, it may be rotated in the reverse direction for the purpose of enhancing the dust scraping efficiency on the floor surface during both cleanings.

そして、本実施の形態のものは、直流ブラシモータ16の回転方向を異ならせる手段として、自律走行による掃除時には使用されずに手動操作による掃除時に使用される手動操作用管機構26内で電力供給線の極性を反転させるという構成を採用しているので、極めて簡単な構成で直流ブラシモータ16の回転方向を異ならせることができる。加えて、自律走行による掃除あるいは手動操作による掃除を行うための動作である、手動操作用管機構26の着脱動作に応じて直流ブラシモータ16の回転方向を切替えることができるので、操作性が良好である。   In the present embodiment, as a means for changing the rotation direction of the DC brush motor 16, power is supplied in the manual operation pipe mechanism 26 that is not used during cleaning by autonomous traveling but is used during cleaning by manual operation. Since the configuration in which the polarity of the line is reversed is employed, the rotation direction of the DC brush motor 16 can be varied with a very simple configuration. In addition, since the direction of rotation of the DC brush motor 16 can be switched according to the attachment / detachment operation of the manual operation pipe mechanism 26, which is an operation for performing cleaning by autonomous driving or manual operation, the operability is good. It is.

さらに、固定機構20による接続管11の固定が解除された状態では、駆動力伝達手段が直流ブラシモータ16の駆動力を駆動車輪2a、2bに伝達せず、しかも、左右の車輪駆動用モータ4a、4bへの給電路が開放される構成となっている。したがって、自律走行による掃除状態から手動操作による掃除を行うために固定機構20による固定を解除すれば、自動的に、掃除機本体1を自律走行させる左右の車輪駆動用モータ4a、4bが停止するとともに駆動車輪2a、2bが回転自在となり、使用者は容易に手動によって掃除機本体1を移動させることができる。   Further, in a state where the fixing of the connecting pipe 11 by the fixing mechanism 20 is released, the driving force transmitting means does not transmit the driving force of the DC brush motor 16 to the driving wheels 2a and 2b, and the left and right wheel driving motors 4a. 4b, the power supply path to 4b is opened. Therefore, if the fixing mechanism 20 is released in order to perform the cleaning by the manual operation from the cleaning state by the autonomous traveling, the left and right wheel driving motors 4a and 4b that cause the cleaner body 1 to autonomously travel automatically stop. At the same time, the drive wheels 2a and 2b are rotatable, and the user can easily move the cleaner body 1 manually.

なお、この実施の形態では床面掃除用ノズル機構12を、その連通管13が前側に位置するように掃除機本体1に取り付けるようにしたが、床面掃除用ノズル機構12の掃除機本体1への取り付け方向はこれに限られるものではない。また、床面掃除用ノズル機構12を掃除機本体1に取り付けた場合と、延長管29に取り付けた場合とで直流ブラシモータ16の回転方向を変えるようにしたが、直流ブラシモータ16の回転方向を常に一定として実施することも可能である。さらに、上記実施の形態においては、固定機構20の固定解除操作に連動して、駆動車輪と左右の車輪駆動用モータとの連結状態を解除するとともに車輪駆動用モータをオフするようにしているが、これら連結状態の解除や車輪用モータのオフ操作を独立して行うようにしてもよい。   In this embodiment, the floor cleaning nozzle mechanism 12 is attached to the cleaner main body 1 so that the communication pipe 13 is located on the front side. However, the cleaner main body 1 of the floor cleaning nozzle mechanism 12 is not shown. The mounting direction is not limited to this. In addition, the rotation direction of the DC brush motor 16 is changed depending on whether the floor cleaning nozzle mechanism 12 is attached to the cleaner body 1 or the extension pipe 29. It is also possible to carry out with always being constant. Further, in the above embodiment, in conjunction with the unlocking operation of the fixing mechanism 20, the connection state between the driving wheel and the left and right wheel driving motors is released and the wheel driving motor is turned off. The connection state may be released and the wheel motor may be turned off independently.
