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.

Abstract: A refrigerator includes a cabinet including a storage space; a main door to open and close the cabinet and defining an opening; and a sub door defining a front surface of the refrigerator and to open and close the opening of the main door. The main door includes a door frame defining the opening and contacting the sub door; a door liner coupled to the door frame to form an insulating space and defining a rear surface of the main door; and an inner frame defined along the opening of the main door inside of the insulating space and to support between the door frame and the door liner, where the inner frame includes a curved portion defined at a rear side of the inner frame, which connects to the door liner.
