Fig. 3 is the cutaway view of demonstration according to the vitals of the robot cleaner of first embodiment.
As shown in Figure 3, the lower surface that first collecting region 40 has level of approximation, and suction inlet 11 is adjacent to the floor layout.Therefore, be introduced into suction inlet 11 in case contain the air of dust, then air flatly flows in first collecting region 40.
Owing to used targeting part 11a, only utilize the dust that is difficult to be inhaled into the phase counterweight in the dust-collector 20 by the suction that produces by air blast 30 easily to be cleaned, and directly be introduced in first collecting region 40 by the rotation of rotating brush 14.As a result, the function of first collecting region 40 can be similar to dust shovel (dust pan), thereby improves the cleaning efficiency of robot cleaner 1.
Be provided with adverse current in the position of the close suction inlet 11 of the upper surface of first collecting region 40 and prevent member 41, with prevent to be collected in the dust-collector 20 the dust adverse current and by suction inlet 11 dischargings.
Adverse current prevents that member 41 is attached to the upper surface of first collecting region 40 by for example hinge 42, but, also can prevent that member 41 rotations are attached to the upper surface of first collecting region 40 with the fastener of any other type of opening/closing suction inlet 11 by allowing adverse current.
When robot cleaner 1 was not worked, adverse current prevented that member 41 is used to close suction inlet 11.As long as robot cleaner 1 beginning clean operation, adverse current prevent that the suction of member 41 by air blast 30 from sucking direction along air and rotating pivotally opening suction inlet 11, thereby allow dust to be inhaled in the dust-collector 20.
In addition, when the work of robot cleaner 1 was finished, adverse current prevented that member 41 from returning to its home position, closing suction inlet 11, thereby prevented that the dust of collecting is discharged into the outside by suction inlet 11.
Though current embodiment has shown adverse current and has prevented that member 41 from being rotated pivotally by the suction of air blast 30, should be appreciated that adverse current prevents that member from can open or close suction inlet by other drive unit.
The end of first collecting region 40 is provided with accelerating part 43, and accelerating part 43 is as the flow channel with the sectional area that reduces.Accelerating part 43 makes air suck that sectional area reduces and makes the flow velocity (flow rate) through the air of first collecting region 40 increase, thereby the inhaled air that allows to contain dust moves upward in second collecting region 50 under the power effect that increases.
Second collecting region 50 that is limited at the top of first collecting region 40 communicates with first collecting region 40 by interface channel 21, and is used for collecting therein light relatively dust.Second collecting region 50 holds filter 51 in the one side, passes through air blast 30 inhaled airs to purify, thereby discharges clean air.Opposite side at second collecting region 50 is provided with division member 52, and division member 52 projects upwards from the bottom of second collecting region 50, passes through interface channel 21 adverse currents in first collecting region 40 with the dust that prevents to be collected in second collecting region 50.
As a result, light relatively dust moves in second collecting region 50 after through first collecting region 40 by the suction of air blast 30.In this case, first collecting region 40 is as the interface channel that light dust is guided in second collecting region 50, and dust can move upward by the interface channel 21 that vertically is limited between first collecting region 40 and second collecting region 50, thereby is collected in second collecting region 50.
Second collecting region 50 has: communication port 53, in the top surface perforation formation of second collecting region 50, to communicate with dust-exhausting port 13; Opening/closing 54 opens or closes communication port 53.In case robot cleaner 1 docks with docking station, then opening/closing 54 is opened communication port 53, to remove the dust that is collected in the dust-collector 20 by communication port 53 and dust-exhausting port 13.
Fig. 5 is the figure that the clean-up performance according to the clean-up performance of the robot cleaner of current embodiment and conventional machines people dust catcher compares.
Here, should notice that Fig. 5 has shown the experimental result that air blast obtained of utilizing the low low-down power (approximately 100W) of the power (approximately 600W) that has than conventional vacuum cleaners.
In addition, should be noted that the cleaning efficiency that shows recently represented with respect to the percentage of the weight that is dispersed in the dust in the presumptive area by the weight that is collected in the dust in the dust-collector in above comparison diagram.
As shown in Figure 5, the cleaning efficiency of previously herein disclosed conventional machines people's dust catcher is 72%, the working method of this robot cleaner is: after the dust on the floor upwards dispersed by brush, the dust that disperses was collected into the filter by suction nozzle with from the vertical tube connector that extends of suction nozzle.Compare with traditional robot cleaner, robot cleaner according to current embodiment can reach 95% cleaning efficiency, in robot cleaner according to current embodiment, the dust of phase counterweight is swept in first collecting region by the rotation of rotating brush, and the suction of light relatively dust by air blast is collected in second collecting region.
Generally speaking, we can say to compare with conventional art and can realize the cleaning efficiency that improves according to the robot cleaner of current embodiment.
Below, with reference to Fig. 3 and Fig. 4 operation according to the robot cleaner of first embodiment is described.
Fig. 4 is the cutaway view of demonstration according to the operation of the robot cleaner of first embodiment.
People's dust catcher 1 if user starts the machine, then air blast 30 and rotating brush 14 are operated.Along with air blast 30 produces suction, as shown in Figure 4, be arranged on adverse current in first collecting region 40 and prevent that member 41 from rotating pivotally opening suction inlet 11, thereby allow dust to be inhaled in the dust-collector 20.
In this case, by the rotation of rotating brush 14, light relatively dust is upwards dispersed, and the dust of phase counterweight is upwards cleaned.Here, the dust of the phase counterweight of cleaning is cleaned continuously by targeting part 11a, thereby is collected in first collecting region 40.
In addition, light dust is through first collecting region 40, and flow velocity increases in the accelerating part 43 that passes through the flow channel with the sectional area that reduces then.As a result, light dust can move upward in second collecting region 50 by interface channel 21.In case light dust moves upward and is collected in second collecting region 50, divide member 52 and can prevent that the dust adverse current is in first collecting region 40.
Then, if the user finishes the operation of robot cleaner 1, then the operation of air blast 30 and rotating brush 14 stops.Along with stopping of air blast 30, the adverse current that is arranged in first collecting region 40 prevents that member 41 from returning to its home position, and closing suction inlet 11, thereby the dust that prevents to be collected in the dust-collector 20 is discharged by suction inlet 11.
The result, the dust-collector 20 that is included in the robot cleaner 1 according to first embodiment can be collected the dust of phase counterweight individually in being limited to first collecting region 40 of its underpart, and collects light relatively dust in second collecting region 50 that limits at an upper portion thereof individually.
When robot cleaner 1 docked with the docking station (not shown), the dust that is collected in the dust-collector 20 can be removed from robot cleaner 1.In addition, not by the dust that is collected in the phase counterweight in first collecting region 40 of the suction of docking station removal can the adverse current of rotary closing suction inlet 11 prevents that member 41 from removing along with the user waits pivotally with his/her finger.
Under situation according to the robot cleaner 1 of first embodiment, though its use has the small-sized relatively air blast 30 of low intake performance, but its rotation by rotating brush 14 can sweep heavy dust in first collecting region 40, simultaneously, can in second collecting region 50, collect light relatively dust by the suction of air blast 30.As a result, even robot cleaner 1 has compact structure, it also can reach maximum clean-up performance, and the adverse current that is arranged in first collecting region 40 by use prevents that member 41 from can prevent that the dust of collecting from discharging by suction inlet 11.
Then, with the robot cleaner of describing according to second embodiment.
In the following description, and will refer to identical label, and will omit description of them according to the identical member of the member of the robot cleaner of previously described first embodiment.
Except the structure of dust-collector, according to the robot cleaner of second embodiment with basic identical according to the robot cleaner of first embodiment.

As shown in Figure 6, be included in have according to the dust-collector in the robot cleaner of second embodiment 60 approximate rectangular box-like.Dust-collector 60 has the suction slot 61 (61a and 61b) that is formed on its underpart, sucks the size of total size of slot 61 (61a and 61b) corresponding to suction inlet 11, and the top of dust-collector 60 is constructed to communicate with air blast 30.
Along with air blast 30 and rotating brush 14 are operated, the dust on the floor can be collected in the dust-collector 60.
Dust-collector 60 comprises top cover 63.Top cover 63 is formed with: opening 64 communicates with dust-exhausting port 13; Opening/closing 65 opens or closes opening 64.In case robot cleaner 1 docks with docking station, then opening/closing 65 is opened opening 64, to remove the dust that is collected in the dust-collector 60 by opening 64 and dust-exhausting port 13.
As shown in Figure 7, the inside of dust-collector 60 is divided into a plurality of collecting regions 70 and 80.More particularly, dust-collector 60 comprises: a pair of first collecting region 70 is used to collect the dust by the revolving force cleaning of rotating brush 14; Second collecting region 80 separates by a plurality of vertical separators 62 and first collecting region 70, and is constructed to communicate with air blast 30, collects dust on the floor with the revolving force of suction by utilizing air blast 30 and rotating brush 14.
Sucking slot 61 comprises: first sucks slot 61b, along the lower end formation of each first collecting region 70; Second sucks slot 61a, along the lower end formation of second collecting region 80.
