Method and apparatus maintaining liquid beverages in a supercooled state

摘要

Disclosed herein is a refrigerator including a device to restrain the freezing of liquid-phase beverages, thereby stably maintaining the supercooled state of the liquid-phase beverages. The refrigerator includes a main body (10), a supercooling chamber (30) disposed in the main body (10) such that cool air is supplied to the supercooling chamber (30), a microwave generator (50) to oscillate microwaves to the supercooling chamber (30), and a control unit (53) to control the magnitude of the microwaves oscillated from the microwave generator (50). The present invention has the effect of restraining the freezing of the liquid-phase beverages, thereby stably maintaining the supercooled state of the liquid-phase beverages, and therefore, increasing the supercooled degree of the liquid-phase beverages.
