Abstract: A dish washer senses an amount of change in a level of a detergent via a floater that moves in a vertical direction based on the level of the detergent and a detergent level sensor that senses a location in the vertical direction of the floater, and effectively identifies a viscosity of the detergent stored in a detergent supply based on the amount of change in the level to simplify a structure, improve space utilization, and reduce a manufacturing cost by eliminating a separate electrode sensor or level sensor to identify the viscosity of the detergent.

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.

Abstract: A dish washer effectively identifies a viscosity of a detergent stored in a detergent supply based on the number of revolutions of a roller sensed via a roller sensor and an operating time of a pump motor, thereby simplifying a structure, improving space utilization, and reducing a manufacturing cost as a separate electrode sensor or level sensor for identifying the viscosity of the detergent is eliminated.
