In addition, below will be along electric dust collector 11(body shell 12) the direction of direction of travel as fore-and-aft direction (arrow A shown in Figure 1, B direction), the left and right directions (two side directions) of (vertical) of intersecting with this fore-and-aft direction describes as width.

Body shell 12 use such as synthetic resin etc. forms smooth cylindric (discoid)---and namely overlook and be toroidal, the revolution on the F of ground becomes and easily consists of.And, possess the lower surface 12a as the toroidal bottom surface in the bottom of this body shell 12, be formed with the suction inlet 24 of the formation dust collecting opening that the long shape of width namely grows crosswise at this lower surface 12a by the width central portion opening at rear portion.

And, although do not illustrate on the top of body shell 12, dispose various guidance panels and display part etc.

In addition, although following lower surface 12a is not as having irregular flat shape to describe, so long as the whole face that forms along the plane of regulation comprises various faces with trickle concavo-convex grade.

Suction inlet 24 be positioned at body shell 12 fore-and-aft direction by rear side, namely than the center of fore-and-aft direction by the rear, have the width dimensions of 2/3 left and right of the width dimensions (diameter dimension) of body shell 12.And this suction inlet 24 is communicated with debris collection section 14.

And the rotary cleaning body that consists of main cleaning body is that the rotating brush 25 of axle shape can rotate the earth's axis and props up on this suction inlet 24, and this rotating brush 25 is by turning motor 26 rotary actuations that are arranged on the cleaning body driving mechanism in body shell 12.

Rotating brush 25 is a plurality of cleaning bodies formations of radially helically installation on the outer peripheral face of long axial region for example.

The below of these rotating brush 25 downsides lower surface 12a of 12 from from suction inlet 24 to body shell is outstanding, and the top and the ground F that are positioned at the cleaning body of downside under the state that electric dust collector 11 is positioned on the F of ground consist of contiguously.

Debris collection section 14 is passed through the driving of electric blower 13 from the part of the dust of suction inlet 24 suctions for capture, can adopt such as dust bags such as paper bags or with the structure of filter trap filter dust, perhaps by inertial separation such as centrifugation (cyclonic separation) or straight line separation with the structure arbitrarily such as structure of dust separation and collection.

And the top that this debris collection section 14 is positioned at suction inlet 24 is the rear portion of body shell 12, can load and unload on body shell 12.

Each driving wheel 15 downside at least is outstanding downwards from the lower surface 12a of body shell 12, can contact and rotate with ground F under the state that electric dust collector 11 is positioned on the F of ground.And these driving wheels 15 are positioned at the both sides that the both sides, the place ahead of suction inlet 24 for example are the fore-and-aft direction substantial middle section of body shell 12, consist of rotationally along fore-and-aft direction.

That is, the turning cylinder of each driving wheel 15 is along the left and right width of body shell 12, in other words is positioned at along the straight line L through the center of overlooking of body shell 12 upper (as the center line of the fore-and-aft direction of diameter) (L is unanimous on the whole with straight line).

Therefore, rotate mutually electric dust collector 11(body shell 12 along opposite direction by making these driving wheels 15,15) turn round in its position on the F of ground.

Each motor 16 for example respectively with the corresponding configuration of driving wheel 15, can drive independently each driving wheel 15.These motor 16 both can be directly connected on each driving wheel 15, also can be connected with each driving wheel 15 by not shown transmission mechanisms such as gear or conveyer belts.

Gyroscope wheel 17 is positioned at substantial middle section and the front portion of the width of body shell 12, for can be along the rotating driven pulley of ground F.

Dust on the ground F on for example wall limit that each side brush 18 holds together that rotating brush 25 grades can not arrive for collection and guiding are to the auxiliary cleaning body of suction inlet 24, have respectively become revolution cleaning section root rotating center section namely as the brush root 31 of rotating shaft, and namely be for example 3 cleaning bodies 32 of radiated entends towards the radial direction of this brush root 31 with direction that this brush root 31 intersects.

And

side brush

18,18 makes and becomes the brush of

pivot root

31,31 and be arranged on the lower surface 12a of body shell 12 in the position of two sides at the rear of suction inlet 24 and driving wheel 15, the place ahead of 15 and gyroscope wheel 17.

Brush root 31 forms the lower surface 12a that has at least along the vertical direction namely with body shell 12 and intersects the axle shape of composition of above-below direction of direction of (quadrature).

As understanding from Fig. 2, each side brush 18 is along ground F(along with respect to the ground F side direction rear side oblique face of square neck up in the past) consist of pivotally.And the upper lateral front side of this brush root 31---namely opposite with driving wheel 15 direction (direction of leaving) tilts.

Therefore, the cleaning body 32 that each side brush 18 is positioned at the front side with respect to brush root 31 tip side more flexibly is crimped on the F of ground, and the cleaning body 32 that is positioned at rear side with respect to brush root 31 tip side is got over the lower surface 12a of the close body shell 12 of built on stilts F().

And cleaning body 32 is for side brush 18(brush root 31) setting example is as 3, roughly equally spaced separates mutually on the circumferencial direction of brush root 31.In addition, cleaning body 32 also can be for brushing 18 setting examples as more than 4 for a side.

And each cleaning body 32 possesses a plurality of bristle 32a as cleaning part in tip side respectively.These bristles 32a is thin-line-shaped with formation such as synthetic resin, has flexibility.

And from the outstanding more large dust that more can collect to hold together wide region of amount of brush root 31, so each cleaning body 32 is set as at least than brush root 31 and the distance of driving wheel 15 on overlooking that is positioned at its rear due to these bristles 32a.

Therefore, bristle 32a gabarit (neighboring) from body shell 12 under the state that is positioned at brush root 31 outsides, the place ahead consists of laterally highlightedly.

And, the bristle 32a of each side brush 18 is being positioned at than brush root 31 by under the state at rear, and the interference section of preventing that is formed between each side brush 18 and (and each side is brushed a side of the 18 near distances) driving wheel 15 that is positioned at its rear on the lower surface 12a of body shell 12 is that recess 35 consists of agley.

Namely, each recess 35 prevents the structure of the interference of this bristle 32a and driving wheel 15 for the bristle 32a bending of each cleaning body 32 of making each side brush 18, possess respectively and overlook for the facial 35a of fan-shaped inclination and the facial 35b of supporting that erects upward from the rearward end of the facial 35a of this inclinations, with respect to the setting of lower surface 12a depression.

The facial 35a that tilts forms and overlooks and brush the concentric shape of root 31, and the cleaning body 32 when avoiding with 18 revolution of side brush is interfered.Be specially, this facial 35a side direction rear side in the past that tilts, in other words, slowly square neck is oblique up from side brush 18 1 side direction driving wheel 15 1 sides, and slowly square neck is oblique up to central portion from the both sides of width.

That is, recess 35 is the darkest at the central portion of width, slowly forms to both sides with shoaling.

And, support facial 35b continuous with the circular arc portion of the facial 35a that tilts, for example form planar (wall shape) with the axial almost parallel of brush root 31, make the top of bristle 32a of butt flexibly crooked.And the facial 35b of this supporting is from continuing slowly to give prominence to towards the top to central portion with continuous both sides, the rear end of the both sides of the facial 35a that tilts.

The rotating shaft that each slewing motor 19 is projected into the below is connected with each brush root 31, can make each side brush 18 width central sides to body shell 12, the side brush 18 that in other words makes the right side to the left, make the side brush 18 in left side namely with each side brush 18, the dust on the F of ground be held together ground to suction inlet 24 side collection to the right to turn round respectively.

Sensor 20 has distance measuring sensors such as ultrasonic sensor or infrared ray sensor or the direct feeler that becomes buffer that contacts with barrier etc., be configured in front portion, sidepiece or the bottom etc. of body shell 12, can detect respectively the having or not and the distance of they and body shell 12 etc. of the place ahead barrier (wall), flanking obstacle (wall) or bottom barrier (step) etc. of body shell 12.

And, controlling organization 22 possesses to be had such as control parts such as the storing mechanisms such as memory and remote controllers, be electrically connected to electric blower 13, turning motor 26, each motor 16, each slewing motor 19 and sensor 20 etc., can control according to the testing result of sensor 20 driving of electric blower 13, turning motor 26, each motor 16 and each slewing motor 19 etc.

Secondary cell 23 is the parts to power supplies such as controlling organization 22, electric blower 13, turning motor 26, each motor 16, each slewing motor 19 and sensors 20.This secondary cell 23 for example is configured in the rear of gyroscope wheel 17.

And this secondary cell 23 is electrically connected to the not shown charging terminal of the lower surface 12a that is positioned at body shell 12, is connected on the not shown charging base that for example is arranged on indoor (room) assigned position by charging terminal and can charges.

The action of above-mentioned the 1st example then is described.

If electric dust collector 11 to for example be set in advance in controlling organization 22 regulation constantly, drive electric blower 13 and leave charging base and begin cleaning.In addition, the position of cleaning beginning can be set in the place arbitrarily such as the position of electric dust collector 11 walking beginnings or the gateway in room.

Then, controlling organization 22

rotary driving motors

16,16 of electric dust collector 11 utilize

driving wheel

15,15 autonomous on the F of ground.At this moment, controlling organization 22 waits and monitors position or the walking states of electric dust collector 11 by the distance of sensor 20 detections and barrier on every side, and according to the detection of these sensors 20, walk on the F of ground in avoid-obstacles limit, limit.

And this electric dust collector 11 sucks the dust on the F of ground by the suction inlet 24 that debris collection section 14 acts on from the negative pressure that the driving by electric blower 13 produces together with air.

Simultaneously, controlling organization 22 is by suitably driving respectively turning motor 26 and slewing

motor

19,19, make rotating brush 25 along ground F rotation and make

side brush

18,18 ground F upper rotary (rotating along the direction of arrow in Fig. 1), bristle 32a by such cleaning body with rotating brush 25 and each side brush 18 etc. will enter the dust of ground F and draw out, central side to the width of body shell 12---namely hold together to suction inlet 24 1 side collection, suck from suction inlet 24.

Wherein, the bristle 32a of each side brush 18 is under each side brush 18 rotating states, be positioned at than the brush root 31 on the front during, be crimped on to former state on the F of ground, be positioned at than brush root 31 by during the rear, the facial 35b of supporting by tip side and each recess 35 interferes and crooked along the gyratory directions of each side brush 18, thereby prevents the interference with each driving wheel 15.

Namely, if cleaning body 32 rearward moves from the place ahead of brush root 31 due to the rotation of each side brush 18, be crimped on the bristle 32a built on stilts F on the F of ground, be crimped at leisure from a side on the facial 35b of supporting of each recess 35, be crimped on the facial 35b of this supporting during, under the effect of frictional resistance, bristle 32a becomes to the rear side of the gyratory directions of each side brush 18 and flexibly curves forniciform state.

Therefore, the top ends of bristle 32a can not be positioned at the position by the rear than the facial 35b of supporting, therefore prevents the interference of bristle 32a and driving wheel 15.

And, if each side brush 18 continues to direction of arrow revolution, the bristle 32a of cleaning body 32 has crossed the opposite side of the facial 35b of supporting of each recess 35, and bristle 32a slowly is disengaged to the crimping of the facial 35b of supporting, bristle 32a flexibly recovers distortion, again with ground F crimping.

The dust that sucks together with air from suction inlet 24 is separated and captures by debris collection section 14, and the air of isolating dust is inhaled into electric blower 13, becomes waste gas wind after cooling in this electric blower 13 to discharge to the outside from body shell 12.

Finish in the situation that be judged to be the cleaning of all ground F that need cleaning, controlling organization 22 makes electric dust collector 11 autonomous to the position of charging base, electric blower 13 and each

motor

19,26 etc. are stopped, and charging terminal (physically be connected) is connected with charging base,

motor

16,16 is stopped, finish operation, with secondary cell 23 chargings.

As mentioned above, according to above-mentioned the 1st example, the recess 35 that is arranged with on the lower surface 12a of body shell 12 by use prevents that as the bristle 32a bending that makes side brush 18 interference that this bristle 32a and driving wheel 15 are interfered from preventing section, thereby these recesses 35 can not interfered or hook with concavo-convex grade of ground F, can not make electric dust collector 11(body shell 12) stop (storehouse), therefore can control more well electric dust collector 11(body shell 12) autonomous.

And, owing to so that be positioned at the mode that the tip side of bristle 32a of the cleaning body 32 of recess 35 sides (rear side) enters each recess 35, the brush root 31 of each side brush 18 being tilted, therefore the place ahead that is positioned at brush root 31 namely is positioned at electric dust collector 11(body shell 12) the bristle 32a of the cleaning body 32 of front side can be more positively and ground F crimping, can not have residually positively the dust collection on the F of ground to be held together.

And each recess 35 can positively make the bristle 32a that enters these recesses 35 crooked by possessing and the facial 35b of the supporting of the tip side crimping of the bristle 32a that is positioned at these recess 35 sides.

Then with reference to Fig. 4 and Fig. 5, the 2nd example is described.In addition, the description thereof will be omitted for the mark additional identical with effect with the same structure of above-mentioned the 1st example.

The 2nd example is to have possessed the form that the guide portion 38 of interfering the section's of preventing effect replaces the recess 35 of above-mentioned the 1st example.

This guide portion 38 prevents the convex protector of the interference of this bristle 32a and driving wheel 15 for the bristle 32a bending that makes each cleaning body 32 in each side brush 18, from the lower surface 12a of body shell 12 towards the below (ground F) outstanding wall-forming shape, possess integratedly be positioned at driving wheel 15 the place aheads become the facial bearing-surface of restriction be front face 38a and the inboard (central side of body shell 12) that is positioned at driving wheel 15 the place aheads to become the facial bearing-surface of restriction be side surface part 38b.Therefore, guide portion 38 bends to and overlooks the font into V.

Front face 38a for example broad ways forms linearity.

And side surface part 38b in the past side direction rear side slowly extends to form obliquely towards the central side of body shell 12 and is for example linearity.

And each side brush 18 intersects (quadrature) brush root 31 and the lower surface 12a of body shell 12---namely have along the vertical direction the direction of principal axis ground configuration of (vertical).Therefore, each side brush 18 consists of pivotally along the face parallel with ground F.

When cleaning, electric dust collector 11 utilizes driving

wheel

15,15 autonomous on the F of ground by controlling organization 22

rotary driving motors

16,16, and controlling organization 22 suitably drives respectively turning motor 26 and slewing

motor

19,19, make rotating brush 25 along ground F rotation and make

side brush

18,18 at ground F upper rotary, the dust that will enter ground F with the cleaning body of rotating brush 25 and the bristle 32a of each side brush 18 etc. is drawn out, and this dust collection is held together and suck from suction inlet 24.

Wherein, the bristle 32a of each side brush 18 is under each side brush 18 rotating states of the edge diagram direction of arrow, be positioned at than the brush root 31 on the front during former state be crimped on the F of ground, be crimped on the F of ground under by the state of brushing 18 gyratory directions bending during the rear by interfering in tip side and each guide portion 38 along each side being positioned at than brush root 31, thereby prevent interference with driving wheel 15.

Namely, if cleaning body 32 rearward moves from the place ahead of brush root 31 by the revolution of each side brush 18, becoming the tip side of bristle 32a and the side surface part 38b of each guide portion 38 connects and flexibly curves forniciform state, if each side brush 18 continues revolution, bristle 32a keeps on the limit crooked state limit and is guided by side surface part 38b, connects with front face 38a subsequently.

Therefore, the top ends of bristle 32a can not be positioned at than the position of guide portion 38 by the rear, prevents the interference of bristle 32a and driving wheel 15.

And if each side brush 18 continues revolution, the bristle 32a of cleaning body 32 has crossed the front face 38a of each guide portion 38, and bristle 32a slowly is disengaged to the crimping of guide portion 38, and bristle 32a flexibly recovers distortion.

Like this, according to the 2nd example, the guide portion 38 that is convexly equipped with on the lower surface 12a of body shell 12 by use prevents section as the interference that makes bristle 32a bending prevent that this bristle 32a and driving wheel 15 from interfering, thereby can keep the interference that prevents bristle 32a and driving wheel 15 under the bristle 32a that makes each side brush 18 and the state that ground F contacts, can positively collect to hold together the dust of ground F.

At least one example according to above explanation, consist of by possessing recess 35 or the guide portion 38 that the crooked interference that prevents that this bristle 32a and driving wheel 15 from interfering of the bristle 32a that makes side brush 18 prevents section between side brush 18 and driving wheel 15, even thereby in the situation that relatively set longways the bristle 32a(cleaning body 32 of side brush 18), also can positively prevent the interference of bristle 32a and driving wheel 15.

Therefore, when near the ground F the barriers such as cleaning such as wall limit, even the distance of body shell 12 and barrier has deviation due to the deviation of sensor 20, by setting more longways the bristle 32a of side brush 18, can efficient collect to hold together well dust.

And, by through overlooking for the driving wheel 15 on the straight line L at the center of the body shell 12 of toroidal with brush 18 in the side in this driving wheel 15 the place aheads between possess recess 35 or the guide portion 38 that prevents section as interference, can be enough the bristle 32a of side brush 18 positively collect to hold together electric dust collector 11(body shell 12) dust on the ground F of direct of travel front side, and the bristle 32a that is positioned at rear side for the revolution due to side brush 18 can by recess 35 or guide portion 38 bendings, can positively prevent the interference with driving wheel 15.

In addition, although controlling organization 22 is except the function of controlling

driving wheels

15,15 rotary actuation by

motor

16,16 in above-mentioned each example, also consisted of integratedly the function of controlling the rotation of

side brush

18,18 by slewing

motor

19,19, the function of the driving of control electric blower 13 and the function of controlling the rotary actuation of rotating brushes 25 by turning motor 26, but these functions also can be distinguished formation individually.

And each side brush 18 can be not only to use the structure of bristle 32a as cleaning part, can be also to use such as extending into banded plate body or the combination of these bristles and plate body etc. to have the structure of flexible cleaning part arbitrarily.

And the cleaning body 32 of each side brush 18 also can be with integral body as bristle 32a.That is, cleaning body 32 is as long as possess bristle 32a in top ends at least, and the root side can at random be set.

And side brush 18 can obtain the action effect same with above-mentioned example so long as have one at least one side in the place ahead of the suction inlet 24 of body shell 12.

And, can also adopt do not possess electric blower 13 and with rotating brush 25, the dust on the F of ground drawn out to the structure of debris collection section 14 controls of dust.

And, electric dust collector 11 is except detecting with the distance of on every side barrier and monitoring position or the walking states of electric dust collector 11 by sensor 20, outside the structure of avoid-obstacles and autonomous, also can adopt such as do not possess sensor, along structure of predefined swept path autonomous etc.

And, although understand several examples of the present utility model, but these examples are demonstration as an example, do not limit the intention of utility model scope.These new examples can be implemented with other various forms, can carry out all omissions, replacement, change in the scope that does not break away from the utility model aim.These examples and distortion thereof not only are included in the scope and aim of utility model, are also contained in the utility model and impartial scope thereof of claim scope record.
