Abstract
The present disclosure relates to a robot cleaner including a body having a space for accommodating a battery, a water container, and a motor therein, a first rotary plate having a lower portion to which a first mop is coupled, and a second rotary plate having a lower portion to which a second mop is coupled, in which the body includes a bottom surface disposed to be directed toward a floor, and mop support portions disposed on the bottom surface, protruding downward, and configured to be in contact with the first mop and the second mop, and the mops are bent by being brought into contact with the mop support portions, thereby increasing a frictional force between the floor and the mops.
Claims20
A robot cleaner comprising:
- a body;
- a first rotary plate rotatably coupled to a bottom surface of the body and having a lower surface facing a floor surface and to receive a first mop;
- and
- a second rotary plate rotatably coupled to the bottom surface of the body and having a lower surface facing the floor surface and to receive a second mop,
- wherein the first mop and the second mop protrude toward the center of the robot cleaner further than the first rotary plate and the second rotary plate, and
- wherein the body comprises one or more mop supports protruding downward from the bottom surface, provided on a connection line extending from a rotary shaft of the first rotary plate to a rotary shaft of the second rotary plate so that the first mop and the second mop are in contact with the mop supports, and disposed above the protruding portions of the first mop and the second mop.
A robot cleaner comprising:
- a body;
- a first rotary plate rotatably coupled to a bottom surface of the body and having a lower surface receiving a first mop and
- a second rotary plate rotatably coupled to the bottom surface of the body and having a lower surface receiving a second mop,
- wherein the first mop and the second mop protrude toward the center of the robot cleaner further than the first rotary plate and the second rotary plate, and
- wherein the body comprises:
- a first rotary shaft hole penetrated by a rotary shaft of the first rotary plate;
- a second rotary shaft hole penetrated by a rotary shaft of the second rotary plate;
- and
- one or more mop supports protruding downward from the bottom surface of the body, positioned between the first rotary shaft hole and the second rotary shaft hole, and configured to be in contact with the protruding portions of the first mop and the second mop.
A robot cleaner comprising:
- a body;
- a rotary plate rotatably provided on a bottom surface of the body;
- and
- a mop having a lower surface facing a floor surface and an upper surface attached to a lower surface of the rotary plate, the mop being configured to rotate together with the rotary plate,
- wherein the body comprises:
- a rotary shaft hole formed in the bottom surface of the body and penetrated by a rotary shaft of the rotary plate;
- and
- a mop support protruding downward from the bottom surface of the body and configured to be in contact with the upper surface of the mop, and
- wherein a distance from the rotary shaft hole to the mop support is greater than a radius of the rotary plate, and
- wherein the portion of the upper surface of the mop, which is in contact with the mop support is distant from the lower surface of the rotary plate.
A robot cleaner comprising:
- a body;
- a rotary plate rotatably provided on a bottom surface of the body;
- a mop having a lower surface facing a floor surface and an upper surface attached to a lower surface of the rotary plate, the mop being configured to rotate together with the rotary plate;
- and
- a mop support protruding downward from the bottom surface of the body and configured to be in contact with the upper surface of the mop,
- wherein a distance between a part of the upper surface of the mop and a part of the lower surface of the rotary plate is changed periodically as the rotary plate rotates.
