  • Patent number: 10161666
    Abstract: A refrigerator having a cool air path damper assembly that can remove dew from the damper housing when the cool air path damper opens and closes. The damper assembly has an anti-freezing pad attached to its upper surface. An elastic anti-freezing member is inserted into the anti-freezing pad. The elastic anti-freezing member moves with the damper when the damper switches between an open and a closed state. During such a motion, the elastic anti-freezing member sweeps through the interior surface of the housing and thereby removes moisture from the interior surface. This can prevent ice formation on the damper due to rapid temperature drop when the damper opens.

  • Patent number: 10161077
    Abstract: A washing machine with a liquid additive supply device capable of sensing an amount of liquid additive contained therein. A buoyancy body and a sensing unit are disposed in a reservoir tank of the liquid additive supply device. The vertical position and therefore the distance between the buoyancy body and a sensing unit vary with the surface level of liquid additive in the reservoir tank due to buoyancy effect. The buoyancy body may include a magnetic body and the sensing unit can detect the intensity of the magnetic body. The surface level of the liquid additive is too low, the sensing unit can generate a signal indicative of liquid additive shortage.

  • Patent number: 10119740
    Abstract: A refrigerator includes an ice-making unit disposed in the door and can make ice through direct cooling by a refrigerant without using cold air flow. A cold air generation system operates to circulate the refrigerant for supplying a cold air flow for the refrigerator. A refrigerant pipe is installed in the refrigerator main body to branch off some refrigerant from the cold air generation system. An ice-making pipe is installed within the ice-making unit and receives the refrigerant from the refrigerant pipe. Water freezes into ice through heat transfer between the ice-making unit and the ice-making pipe containing refrigerant. A soft pipe is disposed around a hinge shaft of the refrigerator main body and the door and configured to interconnect the ice-making pipe and the refrigerant pipe in a twistable manner.
