A cleaning device is provided. The cleaning device includes a vacuum cleaner which includes a dust collecting bin and a docking station to which the vacuum cleaner is coupled, wherein the docking station includes a charger configured to be electrically connected to a charging terminal of the vacuum cleaner in response to the vacuum cleaner being coupled to the docking station, a door driver configured to open or close a dust collecting bin door disposed at a lower portion of the dust collecting bin, a suction device configured to move air from the dust collecting bin into the docking station, a collector configured to collect foreign matter that moves together with the air due to driving the suction device, and a controller configured to control the door driver to open the dust collecting bin door in response to the charging terminal of the vacuum cleaner being electrically connected to the charger, configured to control the suction device to supply a suctioning air flow to the dust collecting bin and perform a discharge operation in response to the dust collecting bin door being opened, and configured to control the door driver to close the dust collecting bin door in response to an end of the discharge operation.

Cleaning device including vacuum cleaner and docking station and control method thereof

A cleaning device and a method therefor are provided. The cleaning device includes a vacuum cleaner including a dust collecting container and a docking station to which the dust collecting container is coupled. The docking station includes a suction device configured to move air from the dust collecting container to inside of the docking station, a collector configured to collect a foreign substance that is moved together with the air by driving of the suction device, a suction flow path along which air moves inside the docking station, a flow adjusting device configured to open or close the suction flow path, and at least one processor configured to control the suction device to operate based on the dust collecting container being coupled to the docking station, and control the flow adjusting device to periodically open and close the suction flow path in a state in which the suction device operates.

Cleaning device having vacuum cleaner and docking station and method of controlling the same

A defrost control method and apparatus for a refrigerator having a defrosting heater for defrosting the evaporator. The method classifies a plurality of operating condition cases based on outside temperature of the cabinet and door opening number. Each of the operating condition cases has a predetermined severity factor. It is obtained a frosting weight for the unit time interval by multiplying a compressor operating time with the severity factor of the operating condition case. The frosting weights for a plurality of the unit time interval are accumulated and a defrosting operation is performed when the accumulated frosting weight exceeds a predetermined value.
