Abstract
A refrigerator includes a thermoelectric element module disposed at a wall of a storing chamber and includes a heat-absorbing sink and a heat-dissipating sink; a supply duct disposed at an inner case to discharge cold air, which has exchanged heat in the heat-absorbing sink, to a storing chamber; and a cold air accumulation agent disposed in the supply duct and cooled by the cold air flowing through the supply duct.
Claims20
A refrigerator comprising:
- a cabinet including an inner case forming a storing chamber, an outer case surrounding the inner case and a cabinet insulator disposed between the inner case and the outer case;
- a door provided at the cabinet, the door to open the storing chamber;
- a thermoelectric element module provided at a wall of the storing chamber and including a heat-absorbing sink and a heat-dissipating sink;
- a supply duct provided at the inner case, the supply duct to discharge cold air heat- exchanged in the heat-absorbing sink to the storing chamber;
- a cold air circulation fan provided at a side of the heat-absorbing sink, the cold air circulation fan to blow the cold air in the storing chamber towards the heat-absorbing sink;
- a phase change material provided in the supply duct, the phase change material to be cooled by the cold air flowing through the supply duct;
- a heat dissipation duct provided at the cabinet insulator, the heat dissipation duct to discharge the air heat-exchanged in the heat-dissipating sink to an outside of the refrigerator;
- and
- a heat dissipation fan provided in the heat dissipation duct, the heat dissipation fan to force external air to flow in the heat dissipation duct,
- wherein the cabinet includes a top wall, a bottom wall and a rear wall,
