Dish washer

Abstract

A dish washer minimizes a possibility of deviation in a detergent supply amount regardless of a change in power supplied to an electric motor by controlling the detergent supply amount based on the number of revolutions of a roller of a detergent pump. The dish washer includes a tub and a detergent supply. The detergent supply includes a container configured to store detergent and a detergent pump configured to supply the detergent in the container to the tub. The detergent pump includes a tube that guides the detergent discharged from the container to the washing space, a roller that pressurizes the tube and revolves about a revolution axis to thereby cause the detergent inside the tube to flow, a pump motor configured to generate driving force to revolve the roller about the revolution axis, and a roller sensor configured to sense a location of the roller.
