Abstract: A countertop water dispenser having a three tiered reservoir system for filtering water and providing immediate dispensing via a spigot, and simultaneously filling a removable pitcher for transporting filtered water to another location. Water flow in the three tiered reservoir system may be controlled by flow valves that float with rising water to stop water flow when a maximum fill level is reached in a reservoir. A flow valve is provided in the middle reservoir as well as the lower reservoir to control the amount of filtered water in each reservoir. An air vent is provided on a filter housing, the air vent venting to a heightened arcuate rib on the countertop dispenser cover. The removable pitcher is mated to the lower reservoir via a pitcher filling mechanism that includes respective plunger or pin valves to allow water to flow into the pitcher when the lower reservoir is filled with water above or equal to the height of the pitcher filling mechanism.

Abstract: A robot cleaner that cleans a cleaning region while traveling the cleaning region and a method to control the same are provided. The robot cleaner can uniformly clean a cleaning region based on a wall-following technique which allows the robot cleaner to travel along the outline of the cleaning region. The method selects, as a reference wall, a wall at a left or right side of the robot cleaner at a start position of the robot cleaner based on a left or right-based travel algorithm, which allows the robot cleaner to travel along a left or right wall, and controls the robot cleaner to travel the cleaning region in a zigzag travel pattern in which the robot cleaner moves a predetermined distance in a direction perpendicular to the reference wall at specific intervals along the selected reference wall while following the selected reference wall.

Abstract: Disclosed herein is a drum washing machine. A rotational track of a first door to open and close an opening of a machine body is concentric with a rotational track of a second door to open and close an opening of a water tub, thereby improving user convenience.

Abstract: Disclosed is a robot cleaner system having superior functions of sucking dust and exhausting dust to a docking station. The robot cleaner includes a dust suction port to suck dust, a dust collecting chamber to collect dust introduced through the dust suction port, a dust exhaust port to exhaust dust collected in the dust collecting chamber to the docking station, a connection path extending from the dust suction port to the dust exhaust port in adjacent to the dust collecting chamber, and a valve device provided between the connection path and the dust collecting chamber, an opening/closing of the valve device allowing the dust collecting chamber to selectively communicate with the dust suction port or the dust exhaust port according to a pressure difference between the dust collecting chamber and the connection path.

Abstract: A robot cleaner system having an improved docking structure between a robot cleaner and a docking station, which is capable of an easy docking operation of the robot cleaner and preventing loss of a suction force generated in the docking station. The robot cleaner includes a docking portion to be inserted into a dust suction hole of the docking station upon a docking operation.
