Abstract
A robot cleaner includes a main body and a wheel installed on the main body and configured to be driven by a driving motor to move the main body. The wheel includes an outer wheel including a tread configured to come into contact with a cleaning target floor and sidewalls provided on both side surfaces of the tread, and an inner wheel installed in the outer wheel and configured to receive a driving force from the driving motor. The outer wheel includes a plurality of tread grooves recessed in the tread. The outer wheel includes a plurality of deforming grooves formed in an axial direction of the outer wheel at positions corresponding to the plurality of tread grooves.
Claims18
A robot cleaner comprising:
- a main body;
- and
- a wheel installed on the main body and configured to be driven by a driving motor to move the main body,
- wherein the wheel includes:
- an outer wheel configured to come into contact with a cleaning target floor, the outer wheel including:
- a tread configured to come into contact with the cleaning target floor,
- a sidewall provided on both side surfaces of the tread, respectively, the sidewall including a first sidewall and a second sidewall,
- a plurality of tread grooves recessed in the tread and provided alternately with a side of a first tread groove of the plurality of tread grooves opening toward the first sidewall and a side of a second tread groove of the plurality of tread grooves opening toward the second sidewall, and
- a plurality of deforming grooves formed in the outer wheel in an axial direction of the outer wheel at positions respectively corresponding to the first tread groove and the second tread groove,
- wherein each tread groove of the plurality of tread grooves extends in the axial direction of the outer wheel to be longer than half of a width of the outer wheel, and
- an inner wheel installed in the outer wheel and configured to receive a driving force from the driving motor.
