On the other hand, when side brush 10 rotates, the pars intermedia 10b of brush bundle 10b 2slidingly contact with the mode and side protuberance Es of crossing over side protuberance Es, thus, side protuberance Es bends in the mode close abreast with vertical central P, and at pars intermedia 10b 2playing a role after crossing over side protuberance Es makes above-mentioned flexure disappear.Thus, such as brush bundle 10b enters the gap between the ground F on floor and carpet J1 deeper and blocks, its result, can prevent the rotation of side brush 10 from stopping this undesirable condition.In addition, the aftermentioned detailed content about this situation.
Side protuberance Es is only arranged on front side, is not arranged on rear portion side.Thus, the leading section 10c of side brush 10b can contact fully with ground, by rotating the dust effectively collecting ground F to suction inlet 6.
In addition, the part that protuberance Es in side is slidingly contacting with side brush 10 has the pars intermedia 10b with side brush 10 2the vertical plane Es almost parallel with vertical central P of contact 1, and at this vertical plane Es 1with the bottom surface 2a of casing 2 1between there is the torsion guide surface Es be connected continuously with them 2.That is, guide surface Es is reversed 2angle of inclination from the bottom surface 2a of casing 2 1to the vertical plane Es of side protuberance Es 1till change continuously in the scope of 0 ~ 90 °.Thus, rotation brush bundle 10b and reverse guide surface Es 2slidingly contact while by vertical plane Es 1guide.In addition, in the present embodiment, exemplified with relative to bottom surface 2a 1vertical plane Es 1angle be the situation of 90 °, but vertical plane Es 1as long as relative to bottom surface 2a 1substantially vertically, also can be 85 ~ 95 ° of degree.
In addition, above-mentioned vertical plane Es is described 1for substantially vertical shape, but can certainly be set to tilt a little.Therefore, about vertical plane Es 1, be from bottom surface 2a 1to the face of hanging down that side protuberance Es hangs down.In the utility model, above-mentioned side protuberance Es is set by (front) side before side brush 10 and achieves the goal.
In addition, center protrusion Ec and pair of right and left side protuberance Es their front side have along with from front towards rear with staged (F side, ground) inclined plane Ef of tilting downwards 1, Ef 3, and have along with (the bottom surface 2a continuously upward from front towards rear at the rear side of center protrusion Ec 1side) inclined plane that tilts.Further, the vertical plane Es of side protuberance Es 1be connected continuously with the inclined plane of the rear side of center protrusion Ec.In addition, in the present embodiment, exemplified with bottom surface 2a 1the inclined plane Ef of side 1with the inclined plane Ef of top (foot) side of side protuberance Es 3clip tabular surface Ef 2with the situation that 2 ladders are arranged, but also can omit tabular surface Ef 2, from bottom surface 2a 1the inclined plane of sequential like is set to the top of side protuberance Es.
Below, the anti-sticking effect of the side brush 10 when with reference to Fig. 3, Fig. 6 (A) ~ Fig. 7 (B) the carpet J1 that when cleaning dust-collecting robot 1 steps up on the F of ground being described.In addition, in Fig. 6 (A) ~ Fig. 7 (B), in order to make the explanation in rotary moving of brush bundle 10b become easy, 1 brush bundle 10b is only illustrated at side brush 10.In addition, in Fig. 6 (A) ~ Fig. 7 (B), the side brush 10 on the right side in pictorial image 3.
Illustrating that, when not arranging side protuberance Es of the present utility model, such as side brush 10 is blocked by the end J1a of carpet J1 and cannot step up the state of carpet J1 with Fig. 9 before this.
In fig .9, when dust-collecting robot 1 makes side brush 10 rotate to arrive the carpet J1 being laid on ground F, under the state that side brush 10 and ground F contact fully, rotate in the mode slipped into below carpet J1.Advanced by dust-collecting robot 1, a brush bundle 10b of side brush 10 enters below carpet J1 further deeper, the root 10b of brush bundle 10b 1near pushed down by the end J1a of carpet J1, the rotary load of side brush 10 is increased.Thus, stop the rotation of side brush 10, the rotation of drive motors stops (locked).That is, before the brush bundle 10b of side brush 10 rotates and deviates from below carpet J1, occur above-mentioned condition, rotation is prevented from.
To this, as the following describes, by arranging side protuberance Es of the present utility model to eliminate above-mentioned condition.
First, as shown in Fig. 3 and Fig. 6 (A), dust-collecting robot 1 makes side brush 10 rotation advance to arrow Q direction on the ground F on floor.Now, around the leading section 10b of the brush bundle 10b of vertical central P rotation 3contact fully with ground F, to ground F cleans, dust is assembled to suction inlet 6 side.
Further, as shown in Fig. 6 (B), brush bundle 10b rotates with the carpet J1 be layered on the F of ground close, as shown in Fig. 7 (A), and the leading section 10b of brush bundle 10b sometimes 3the clearance G between ground F and carpet J1 can be entered.Now, the pars intermedia 10b of the brush bundle 10b rotated to arrow R1 direction 2from the bottom surface 2a of casing 2 1the torsion guide surface Es of lateral side protuberance Es 2mobile, with torsion guide surface Es 2slidingly contact while by vertical plane Es 1guide.
Thus, the pars intermedia 10b of brush bundle 10b 2bend downwards due to side protuberance Es, brush bundle 10b is on the whole with S oxbow.Now, with the leading section 10b of the brush bundle 10b of S oxbow 3enter the size L of the clearance G between ground F and carpet J1, with the leading section 10b of the brush bundle 10b still keeping extending as shown in Figure 9 3the size entering clearance G is compared short.In other words, due to the effect of side protuberance Es, make the leading section 10b of brush bundle 10b 3the clearance G between ground F and carpet J1 can not be entered deeper.And before brush bundle 10 is pushed down by the end J1a of carpet J1, the brush bundle 10 that maintenance can be made to rotate is deviate from below carpet J1.
Therefore, even if the leading section 10b of brush bundle 10b 3enter clearance G, as shown in Fig. 7 (B), rotated by brush bundle 10b, leading section 10b 3also can easily deviate from from clearance G.Now, can not offside brush 10 drive motors apply excess load.In addition, if side brush 10 and the end of carpet J1 keep to a certain degree, distance ground is close, then brush bundle 10b can not enter clearance G, and rotates in inswept mode on the end J1a of carpet J1.

Imagination is when the distance of the side protuberance Es of Thickness Ratio from ground F to dust-collecting robot 1 of carpet J2 is thick, when dust-collecting robot 1 advances towards carpet J2, before side brush 10 moves to the position of end J2a of carpet J2, end J2a and side protuberance Es and center protrusion Ec collides, and dust-collecting robot 1 cannot be advanced.
To this, dust-collecting robot 1 of the present utility model, is provided with the inclined plane Ef along with stepwise tilting from front towards rear downwards at the front side of center protrusion Ec and pair of right and left side protuberance Es 1, Ef 3.That is, as shown in Fig. 8 (A), when before dust-collecting robot 1 and then with inclined plane Ef 1, Ef 3when meeting the end J2a of thick carpet J2, as shown in Fig. 8 (B), inclined plane Ef 1, Ef 3in the J2a cunning of end, center protrusion Ec and pair of right and left side protuberance Es is made to step up carpet J2.Now, side brush 10 carries out the action illustrated in Fig. 6 (A) ~ Fig. 7 (B), therefore, and the leading section 10b of brush bundle 10b 3even if enter the gap between ground F and carpet J2, also easily can deviate from, make whole dust-collecting robot 1 step up thick carpet J2 and continue cleaning work.
In addition, according to dust-collecting robot of the present utility model and self-propelled suction cleaner 1, due to the effect of side protuberance Es can be utilized to prevent side brush 10 from blocking, therefore, without the need to the root 10b from brush bundle 10b 1to pars intermedia 10b 2cover cartridge unit and strengthen brush bundle.Therefore, component quantity can not be increased, the formation of simplified side brush 10 and to manufacture at a low price.
And, according to self-propelled suction cleaner of the present utility model, 10b can be restrainted at small-sized brush pedestal 10a with the multiple brush of radial implanting, therefore, not only can also clean at lower zone brush bundle 10b in the neighboring area of the brush pedestal 10a of the ground F that will clean, the cleaning that can reduce side brush is uneven.
