- the rotation shaft 29a of the drive wheel 29 may be arranged so as to be shifted from the center line C of the main body housing 2, it is more desirable to arrange the rotation shaft 29a on the center line C as in the present embodiment. Thereby, the weight of the main body casing 2 is distributed in a balanced manner with respect to the center, and the fall of the main body casing 2 at the step can be more reliably prevented.
- the rotating brush 9 provided in the suction port 6 in front of the driving wheel 29, the rear wheel 26 disposed behind the driving wheel 29, and the driving wheel 29 are grounded and self-propelled on the floor surface F, The dust in front of the course can be guided to the suction port 6 without being blocked. Further, when the main body housing 2 moves forward and stops suddenly, the center of gravity of the main body housing 2 moves forward, the rotating brush 9 is deformed, and the main body housing 2 tilts forward. At this time, the main body housing 2 returns to the original posture because the weight is distributed back and forth. Therefore, even in the main body housing 2 that easily tilts forward at the time of a sudden stop because it is not grounded in front of the suction port 6, it is possible to prevent a drop at a step.
- control board 15 is arranged on the same side as the battery 14 with respect to the dust collecting unit 30, the heavy electric blower 22 is arranged in the front, the control board 15 and the battery 14 are arranged in the rear, and the driving wheel 29 On the other hand, it is possible to achieve a better weight balance before and after. Therefore, it is possible to more reliably prevent the main body housing 2 from dropping at a step.
- an air flow path (first and second intake passages 11 and 12, first and second exhaust passages 24 a and 24 b) is disposed in front of the dust collection unit 30, and a control board 15 is disposed in the rear. .
- the air flow path and the control board 15 are collectively arranged. Thereby, while shortening an air flow path, wiring etc. can be reduced and size reduction of the main body housing
- the dust collection chamber 39 extends in one direction and partitions the inside of the main body housing 2a, the air flow path and the control board 15 can be easily isolated. Further, the first and second intake passages 11 and 12 are led out to the front wall extending in the longitudinal direction of the dust collection chamber 39, and the other wall surfaces of the dust collection chamber 39 are closed. Thereby, even if airflow leakage occurs at the inflow port 34a or the outflow port 35a, dust is trapped inside the dust collection chamber 39. Therefore, the adhesion of dust to the control board 15 can be further reduced.
- the inflow port 34a is opened in the dust collecting container 31, and the outflow port 35a is opened in the upper cover 32 having the filter 33, the dust accumulated in the dust collecting container 31 is easily discarded by opening and closing the upper cover 32. be able to.
- the opening surfaces of the inlet 34a and the outlet 35a are formed by inclined surfaces, and the packing is arranged on the periphery of the opening surface, so that it is possible to prevent deterioration of the packing due to sliding when the dust collecting part 30 is put in and out. it can.
- the electric blower 22 is arranged in front of the dust collecting unit 30 and the battery 14 and the control board 15 are arranged in the rear.
- the electric blower 22 is arranged on one side with respect to the dust collecting unit 30.
- the battery 14 and the control board 15 may be disposed on the other side.
- the air flow path is arranged in front of the dust collection unit 30 and the control board 15 is arranged behind.
- the air flow path is arranged on one side of the dust collection unit 30 and the control board 15 is arranged on the other side. That's fine.
- the present invention can be used for a cleaning robot that runs on the floor surface.
