1. A washing machine comprising:
a tub having an open top surface;
a housing covering the tub; and
a detergent supplier forming a detergent supply path along which water and a detergent are suppliable to the tub, and including:
a detergent container configured to store detergent,
a buoyancy-type sealing member in the detergent supply path,
a detergent container cover covering at least a portion of the detergent container and including:
a detergent opening formed on a bottom side of the detergent container cover and through which the detergent supply path extends, and
a protrusion protruding from an inner side of the detergent opening and configured to support the buoyancy-type sealing member,
wherein the detergent container cover is configured so that:
with water being back-flowed from the tub along the detergent supply path, the buoyancy-type sealing member arranged in is moved along the detergent supply path by buoyancy to be supported by the protrusion and close the detergent supply path so as to prevent the back-flowed water from flowing through the detergent opening.
