Also, in the case of storing dust robot 1 after terminating to clean, draw-out handle 32 lifts dust robot 1 And reception position is carried to, tabular surface 63 is erected dust robot 1 with being below.Then, such as Fig. 5 institutes Show, tabular surface 63 is placed in ground L, and dust robot 1 is erected alone with longitudinal posture, therefore, it is possible to parallel with wall etc. Posture store at steady state.Especially herein, battery 3,3 is erected alone with being below, therefore, stood alone Center of gravity is located at downside under the state of rising, and turns into more stable state.

In addition, under raised state alone, outer exhaust outlet 50 compared to tabular surface 63 by inboard recess 64 be open without Directly contacted with ground L, therefore, be also difficult to be attached to outer exhaust outlet 50 even if dust etc. on the L of ground be present.

And then under the raised state alone of dust robot 1, the disposal box 7 in main part 2 is in upper and lower suction inlet 37th, 38 longitudinal posture upward, therefore, overflowed without the dust worried in disposal box 7.

Also, under raised state alone, the sensor wrap 12 positioned at upside declines because of deadweight, and turning into makes collision sensing The position that device is connected.Therefore, it is possible to assign following functions：When forget close power knob 57 in the state of erect storage alone When, if controller 52 confirms to detect that the connection signal of crash sensor continues more than stipulated time this case, automatically Ground deenergization.

So, according to the dust robot 1 of aforesaid way, set what can be erected alone with longitudinal posture in main part 2 Bearing-surface (tabular surface 63), thus, it is possible to the stable longitudinally disposed storage of state.

Especially herein, bearing-surface is set to the tabular surface 63 for carrying out chamfering along the side face of main part 2 and being formed, therefore, Even if set bearing-surface will not also be protruded from main part 2, without having to worry about dust robot 1 in narrow local conversion direction with The interference such as barrier of surrounding.

In addition, tabular surface 63 is arranged at the carrying side of battery 3, therefore, forms the longitudinal direction that battery 3 is below and set Put, center of gravity is located at downside, can realize erecting alone for each stabilization.

And then recess 64 is formed in tabular surface 63, the outer exhaust outlet 50 of exhauster(-tor 48 is formed in recess 64, therefore, The dust on ground etc. is difficult to be attached to outer exhaust outlet 50 when erecting alone, can reduce the misgivings of exhaust efficiency reduction.

In addition, in aforesaid way, tabular surface is arranged to the rear portion of main part, but anterior, sidepiece can be arranged at And realize and erect alone, multiple tabular surfaces can also be set and erected alone towards realization with arbitrary.In addition, as bearing-surface Tabular surface is not limited to, can also be formed as realizing anti-skidding with raised, groove male and fomale(M＆F).

But the longitudinally disposed storage of dust robot is not limited to be based on bearing-surface, foot can also be set and reality Now erect alone.Show to set the modification of the foot in Fig. 6~Fig. 9.

In dust robot 1A, set before sensor wrap 12 and in left and right in a manner of it can take out and take in Put a pair of foots 65,65.The foot 65 is formed as the phase of housing recess 66 with the setting that is recessed along the outer peripheral face of sensor wrap 12 The tabular of ground bending is answered, is linked left right lateral end in a manner of it can rotate using the axle (not shown) of above-below direction. Further, it is possible to as shown in Figure 6 from sensor wrap 12 forward in expand shape it is prominent and with the outer offset of housing recess 66 Terraced portion 67 abut so as to by the pull-out location of limitation rotation, with being folded in as shown in Figure 7 in housing recess 66 without from biography It is taken out and takes between the reception position that sensor cover 12 protrudes.

Therefore, when being cleaned, if foot 65,65 is folded into reception position, foot like that as shown in Figure 7,8 65th, 65 cleaned with will not turning into obstruction.Also, in the case where storing dust robot 1A, if as shown in Figure 9 Foot 65,65 is drawn out to pull-out location respectively and erect the side of sensor wrap 12 on the L of ground with being below, then is being sensed The central portion of device cover 12 is supported in the state of being connected to ground L by the foot 65,65 of the both sides, so as to dust robot 1A alone Erect, therefore, it is possible to be stored at steady state with the posture parallel with wall etc..In this case, can equally assign such as Lower function, because the sensor wrap 12 of ground side is pressed into the position for connecting crash sensor because of the weight of main part 2, Therefore, forget to close power supply and when dust robot is erected into storage alone, if controller 52 confirms to detect that collision passes The connection signal of sensor continues more than stipulated time this case, then automatically deenergization.

Thus, in the dust robot 1A of the modification, by the way that foot 65,65 in pull-out location and can be stored The mode taken out and taken in relative to main part 2 between position is set, being capable of longitudinally disposed storage at steady-state.This Outside, foot 65,65 is accommodated in reception position when being cleaned, walked thus without hindering.

In addition, the mode of foot is not limited to above-mentioned example, foot can be also arranged to rear portion, the sidepiece of main part, Or it is arranged to plane, can be folded towards bottom surface.In addition, it is also considered that be not fold but can be along the radial direction of main part Take out and the mode of income sets foot.

On the other hand, in aforesaid way, modification, dust robot is made to erect alone using bearing-surface, foot, but Such as can also be as shown in Figure 10 dust robot 1B it is such, below the main part 2 before and after be provided as support A pair of chamfered sections 68,68, make the chamfered section 68 of a side be abutted with ground L, make the chamfered section 68 of the opposing party and as by facade Wall W is abutted, thus, it is possible to maintain by standing position gesture and with skewed longitudinally disposed.

So, if setting chamfered section 68,68, dust robot 1B by vertical stable posture, can not be along wall W Longitudinally disposed storage is rolled or fallen, also can simply form support using chamfered section 68.In this case, also may be used In the slip-proofing device of the adhesive rubber of chamfered section 68 etc. or to set bumps, groove etc. to increase the friction between ground etc..Separately Outside, chamfered section can be arranged at the lower surface of the left and right of main part, may not be a pair and only set chamfering in any one party Portion.

In addition, in dust robot, as dust collection function, without being provided simultaneously with main brush and side brush, side can also be omitted Brush and only possess main brush.In addition, dust path is also not limited to the situation of inferior division, can also be existed by single path Disposal box carries out dust.Therefore, the form of disposal box can suitably use form without pallet etc., can also not have Disposal box, and directly stockpile dust in main part.It is in rounded shape that main part is also not limited to top view.In addition, even The type of cleaning floor while dust and the type cleaned are carried out without dust, can also use and erect construction alone.

And then the number of battery is not limited to two, if can left-right balance configure well, just also can Use more than three batteries.Also, the even opposite type of direct of travel, i.e. battery and castor are located at main part Front portion, suction inlet is located at self-propelled dust robot as the rear portion of main part, can also apply the utility model.
