Abstract
Provided are a cleaner having a circulation system of collecting water used in damp cloth, filtering the same, and supplying the filtered water to the cloth, and a control method thereof. The cleaner includes a storage unit storing water, a collecting unit intaking water used in a cloth and introducing intaken water to an upper side of the storage unit, a filter unit filtering water collected by the collecting unit, a water supply unit allowing water within the storage unit to flow out from a lower portion of the storage unit so as to be supplied to the cloth, a vacuum motor operated to cause water to be intaken to the storage unit through the collecting unit, and a pump operate to allow water to be transferred through the water supply unit.
Claims20
A cleaner comprising:
- a rotary plate;
- a cloth that is attached to a bottom of the rotary plate and that is configured to receive water;
- a rotation driving unit that is connected to an upper portion of the rotary plate and that is configured to rotate the rotary plate about an axis that is perpendicular to the rotary plate;
- a storage unit that is configured to store water;
- a collecting unit that is configured to collect water from the cloth and that is configured to provide water to an upper side of the storage unit;
- a filter unit that is configured to filter water that is collected by the collecting unit;
- a water supply unit that is configured to receive water from a lower portion of the storage unit and that is configured to provide water to the cloth;
- a vacuum motor that is configured to move water from the storage unit through the collecting unit;
- and
- a pump that is configured to move water through the water supply unit.
A method for controlling a cleaner that includes a cloth, a storage unit that is configured to store water, a water supply unit that is configured to supply water from the storage unit to the cloth, and a collecting unit that is configured to collect water from the cloth and provide water to the storage unit, wherein the method comprising:
- activating the cleaner;
- sensing a water level within the storage unit;
- determining whether the sensed water level is equal to or higher than a first predetermined reference;
- and
- based on the sensed water level being equal to or higher than the first predetermined reference, deactivating the cleaner, and based on the sensed water level being lower than the first predetermined reference, continuing to operate the cleaner.
A method for controlling a cleaner that includes a cloth, a storage unit that is configured to store water, a water supply unit that is configured to supply water from the storage unit to the cloth, and a collecting unit that is configured to collect water from the cloth and provide water to the storage unit, wherein the method comprising:
- activating the cleaner,
- sensing a weight of water within the storage unit;
- determining whether the sensed weight is equal to or greater than a third predetermined reference;
- and
- based on the sensed weight being equal to or greater than the third predetermined reference, deactivating the cleaner, and based on the sensed weight being lower than the third predetermined reference, continuing to operate the cleaner.
