REFRIGERATOR

摘要

A refrigerator is provided to improve supercooling effect and to lower a supercooling temperature by installing a piezoelectric matrix on an inner wall of a supercooling container and applying power to the piezoelectric matrix using a power unit. A refrigerator comprises a supercooling chamber, plural supercooling containers(30), and a piezoelectric member. The supercooling chamber is installed in the body to supercool a beverage. The supercooling containers are formed in the supercooling chamber and store the beverage. The piezoelectric member prevents freezing of supercooled water and has a piezoelectric matrix(40) and a power unit. The piezoelectric matrix is formed on an inner wall of the supercooling container. The power unit applies power to the piezoelectric matrix.
