Abstract

The invention provides a refrigerator including: a main body having a storage chamber; a door for opening and closing the storage chamber; a thermoelectric module for cooling the storage chamber; an outside temperature sensor for detecting an outside temperature; a storage chamber temperature sensor for detecting the storage chamber temperature; and a control unit for applying a voltage within a range between the maximum voltage and the minimum voltage to the thermoelectric module. The control unit applies the set voltage, not the maximum voltage, to the thermoelectric module when the outsidetemperature is the uppermost outside temperature range among the plurality of outside temperature ranges and thus there is an advantage that the temperature of the control is lowered unit and power consumption is reduced.

Description

technical field [0001] The present invention relates to a refrigerator, and more specifically, to a refrigerator using a thermoelectric module to cool a storage room. Background technique [0002] Refrigerators are devices that refrigerate or store food, medicines, and cosmetics at low temperatures to prevent them from rotting or deteriorating. [0003] The refrigerator includes: a storage room for storing food or medicines or cosmetics; and a cooling device for cooling the storage room. [0004] An example of the cooling device may be constituted by a refrigeration cycle device including a compressor, a condenser, an expansion mechanism, and an evaporator. [0005] Another example of the cooling device may be constituted by a thermoelectric module (TEM: Thermoelectric Module). The thermoelectric module utilizes a phenomenon that, when different metals are combined and current is passed, a temperature difference is generated on both end surfaces of the different metals. ...
