Abstract: A dishwasher includes a cabinet having a tub, a pump and at least one spray arm. The at least one spray arm has a flow path guide and first and second flow channels separated from each other. The flow path guide has a first opening to allow wash water to flow to the first flow channel and a second opening to allow wash water to flow to the second flow channel. A valve is coupled to the flow path guide and is configured to open or close one of the first opening and the second opening. The valve includes a rotatable float. The rotatable float closes the first opening while opening the second opening at a first point in time, and the rotatable float rotates to open the second opening while closing the second opening at a second point in time.

Abstract: A dishwasher includes a tub to provide a wash space, a first rack located inside the tub to receive a washing object and a second rack located below the first rack, a flow path tower provided at the second rack to eject wash water to the first rack, an ejection arm including a chamber for introduction of wash water, a first flow path in communication with the chamber, and second and third flow paths in communication with the chamber to eject wash water to the second rack and separated from each other, a tower separable coupler provided inside the ejection arm to connect the first flow path to the flow path tower when wash water is supplied to the first flow path, and a flow path switcher provided inside the chamber to selectively open the first, second and third flow paths according to a pressure inside the chamber.

Abstract: A laundry treatment apparatus including a front panel with an inclined front surface and an opening for the introduction and removal of laundry located on the inclined surface, a door rotatably mounted to the inclined front surface to open or close the opening, and a damper module between the front panel and the door to apply torque to the door in a direction opposite to a rotating direction of the door when the door is rotated due to self-load (or self-weight) of the door.
