Abstract

A vacuum cleaner includes a driving wheel, a cleaning part, a dust-collecting unit, a dust collection amount detection part, and a travel control part. The dust collection amount detection part detects the amount of the dust and dirt accumulated in the dust-collecting unit. The travel control part controls the driving of the driving wheel to make the vacuum cleaner travel autonomously. The travel control part makes the vacuum cleaner travel to a dust station in the case the amount of the dust and dirt detected by the dust collection amount detection part is equal to or more than a specified amount while the cleaning part performs cleaning. The travel control part further makes the vacuum cleaner undock from the dust station to restart the cleaning after the dust and dirt accumulated in the dust-collecting unit is transferred to a dust-collecting container at the dust station. The vacuum cleaning apparatus can adopt a downsized vacuum cleaner while ensuring convenience.

Claims (35)

1. A vacuum cleaning apparatus comprising:

a vacuum cleaner configured to travel autonomously; and

a station device including a dust storage part configured to receive and store at least a part of dust and dirt collected and caught by the vacuum cleaner,

the vacuum cleaner including:

a travel driving part;

a cleaning part configured to perform cleaning to remove dust and dirt;

a dust-collecting unit configured to accumulate the dust and dirt removed by the cleaning part;

a dust collection amount detector configured to detect an amount of the dust and dirt accumulated in the dust-collecting unit;

a secondary battery; and

a travel controller configured to control driving of the travel driving part so as to make the vacuum cleaner autonomously travel, so as to make the vacuum cleaner travel to the station device when the amount of the dust and dirt detected by the dust collection amount detector is equal to or more than a specified amount while the cleaning part performs the cleaning, wherein

the travel controller is configured to make the vacuum cleaner undock from the station device to restart the cleaning, after the dust and dirt accumulated in the dust-collecting unit is transferred to the dust storage part at the station device without charging the secondary battery via the station device when a remaining capacity of the secondary battery is sufficient for cleaning after the restart of the cleaning, and

the travel controller is configured to make the vacuum cleaner undock from the station to restart the cleaning after the dust and dirt accumulated in the dust-collecting unit is transferred to the dust storage part at the station device and shortage of the secondary battery is charged via the station device when a remaining capacity of the secondary battery is insufficient for cleaning after the restart of the cleaning.

2. The vacuum cleaning apparatus according to claim 1 , wherein

the vacuum cleaner includes a map retaining part configured to generate or retain a map of a cleaning area, and

the travel controller makes the vacuum cleaner travel to the station device on a basis of the map retained by the map retaining part.

3. The vacuum cleaning apparatus according to claim 1 , wherein

the cleaning part is stopped when the amount of the dust and dirt detected by the dust collection amount detector is equal to or more than the specified amount and when the travel controller makes the vacuum cleaner travel to the station device.

4. The vacuum cleaning apparatus according to claim 1 , wherein

the travel controller increases a traveling speed as compared to a normal traveling speed, when the amount of the dust and dirt detected by the dust collection amount detector is equal to or more than the specified amount and when the travel controller makes the vacuum cleaner travel to the station device.

5. The vacuum cleaning apparatus according to claim 1 , the vacuum cleaning apparatus comprising:

a notification part configured to issue a notification when the amount of the dust and dirt detected by the dust collection amount detector is equal to or more than the specified amount and when the travel controller makes the vacuum cleaner travel to the station device.

6. The vacuum cleaning apparatus according to claim 1 , wherein

when the cleaning is restarted after the dust and dirt accumulated in the dust-collecting unit is transferred to the dust storage part at the station device, the travel controller makes the vacuum cleaner undock from the station device and travel to a position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to be equal to or more than the specified amount.

7. The vacuum cleaning apparatus according to claim 2 , wherein

the vacuum cleaner includes the map retaining part configured to generate or retain the map of the cleaning area, and

the travel controller makes the vacuum cleaner travel to the position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to be equal to or more than the specified amount, on a basis of the map retained by the map retaining part.

8. The vacuum cleaning apparatus according to claim 6 , the vacuum cleaning apparatus comprising:

a feature storage part configured to store a feature of the position where the amount of the dust and dirt detected by the dust collection amount detector has been determined to be equal to or more than the specified amount when the amount of the dust and dirt is equal to or more than the specified amount and when the travel controller makes the vacuum cleaner travel to the station device, wherein

the travel controller makes the vacuum cleaner to the position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to be equal to or more than the specified amount, on a basis of the feature stored in the feature storage part.

9. The vacuum cleaning apparatus according to claim 7 , wherein

the cleaning part is stopped when the travel controller makes the vacuum cleaner travel from the station device to the position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to be equal to or more than the specified amount.

10. The vacuum cleaning apparatus according to claim 7 , wherein

the travel controller increases the traveling speed as compared to the normal traveling speed, when the travel controller makes the vacuum cleaner travel from the station device to the position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to be equal to or more than the specified amount.

11. The vacuum cleaning apparatus according to claim 7 , the vacuum cleaning apparatus comprising:

a notification part configured to issue a notification when the travel controller makes the vacuum cleaner travel from the station device to the position where the amount of the dust and dirt accumulated in the dust-collecting unit has been determined to he equal to or more than the specified amount.
