Abstract: A refrigerator may include a temperature sensor, a thermoelectric device module having a thermoelectric device, and at least one fan and configured to cool a storage compartment, and a controller that controls the output power of the thermoelectric device based on the temperature of the storage compartment, a set temperature, and the outside temperature. The output power of the thermoelectric device may be determined based on whether the temperature of the storage compartment is within a first temperature region including the set temperature, a second temperature region, or a third temperature region. In the first and second temperature regions, the thermoelectric device may operate at different output power and which gradually increases as the outside temperature increases. In the third temperature region, the thermoelectric device may operate at a third output power which exceeds the first output power and is greater than or equal to the second output power.

Abstract: A refrigerator includes a thermoelectric element module, and a defrosting temperature sensor, and a controller configured to control operation of the thermoelectric element module. The thermoelectric element module includes a thermoelectric element including a heat absorption portion and a heat dissipation portion, a first heat sink in contact with the heat absorption portion, a first fan facing the first heat sink, a second heat sink in contact with the heat dissipation portion, and a second fan facing the second heat sink. The controller is configured to initiate a natural defrosting operation for removing frost on the thermoelectric element module at every preset period, and terminate the natural defrosting operation based on a temperature measured by the defrosting temperature sensor corresponding to a reference temperature. The controller is configured to control operation of the thermoelectric element and rotation of the first and second fans in the natural defrosting operation.
