  • Patent number: 10260796
    Abstract: A refrigerator includes a compressor to compress refrigerant, a condenser to liquefy the refrigerant supplied from the compressor, a capillary tube to decompress and expand the refrigerant supplied from the condenser, an evaporator to vaporize the refrigerant supplied from the capillary tube, a shutoff valve installed at an inlet of the capillary tube so as to prevent the refrigerant in the condenser during stoppage of the compressor from being moved to the evaporator, and a control unit to enable the shutoff valve to be blocked together so as to prevent movement of the refrigerant from the condenser to the evaporator during stoppage of the compressor, and to enable the shutoff valve to be opened together so as to move the refrigerant from the condenser to the evaporator during starting of the compressor.
    Type: Grant
    Filed: December 15, 2015
    Date of Patent: April 16, 2019
    Assignee: SAMSUNG ELECTRONICS CO., LTD.

  • Publication number: 20060248915
    Abstract: A refrigerator having a main body cabinet comprising an outside cabinet forming outer appearance and an inside cabinet provided with a filling distance of foaming material inside the outside cabinet and formed with a freezer and a cooler, a freezer evaporator and a cooler evaporator, a freezer fan and a cooler fan ventilating cold air formed from the freezer evaporator and the cooler evaporator toward the freezer and the cooler, includes: a cooler duct forming a cold air pathway between the cooler evaporator and the cooler, and having at least one inlet and an outlet formed at an upper side of the cooler evaporator; an airing duct provided to communicate with the cooler duct and a lower area of the cooler to make the cold air go in and out; wherein the cold air of the cooler is introduced into the cooler evaporator through the inlet and the air duct when the cooler fan turns on, the cold air formed from the cooler evaporator flows out to the cooler via the airing duct when the cooler fan turns off.
