Benefits of technology

The present invention is about a cooling apparatus that can be added to a refrigerator without significantly modifying its construction. The apparatus includes a non-freezing apparatus that can store food and beverages in a non-frozen state and easily make slush. This technology uses a supercooling phenomenon, which refers to the phenomenon where a molten object or solid does not change in its state when cooled below its phase transition temperature. The invention provides a simple and efficient way to cool down food and beverages without the need for a complicated apparatus or high power consumption.

Problems solved by technology

However, when the food is stored in the supercooled state by slowing down the temperature change in the supercooling room by indirect cooling, it takes a long time for the food to reach the supercooled state.
Moreover, if the temperature in the refrigerator is reduced to a temperature below a set temperature, there is no construction for raising the temperature.
Accordingly, the refrigerator also has low stability in maintaining a non-frozen state.

Embodiment Construction

[0056]Hereinafter, the present invention will be described in detail with reference to the exemplary embodiments and the accompanying drawings.

[0057]FIG. 3 is a view showing a supercooling process applied to a non-freezing apparatus and a cooling apparatus according to the present invention. As illustrated in FIG. 3, a container C containing a liquid L is cooled in a cooling space S.

[0058]For example, it is assumed that a cooling temperature of the cooling space S is lowered from a room temperature to a temperature below 0° C. (the phase transition temperature of water) or a temperature below the phase transition temperature of the liquid L. While the cooling is carried out, it is intended to maintain the water or the liquid L in a supercooled state at a temperature below the maximum ice crystal formation zone (about −1° C. to −5° C.) of the water in which the formation of ice crystals is maximized, or at a cooling temperature below the maximum ice crystal formation zone of the liqu...

Abstract

The present invention relates to a cooling apparatus including a non-freezing apparatus which can be installed in a refrigerating chamber or a refrigerating chamber door and stably store food in a non-frozen state. A cooling apparatus includes a freezing chamber, a refrigerating chamber, a freezing chamber door, a refrigerating chamber door, and a non-freezing apparatus installed in the refrigerating chamber or the refrigerating chamber door and storing food in a non-frozen state. In the non-freezing apparatus, since a lower space is cooled by the cool air introduced from the freezing chamber and an upper space is cooled by the atmosphere of the refrigerating chamber, it is possible to reduce a heating value of a heater which is operated to maintain the temperature of the upper space to be higher than that of the lower space.

Description

TECHNICAL FIELD[0001]The present invention relates to a cooling apparatus including a non-freezing apparatus, and, more particularly to, a cooling apparatus including a non-freezing apparatus which can be provided in a cooling apparatus such as a general refrigerator without significantly modifying the construction of the cooling apparatus and which can store food and beverages in a non-frozen state and easily make slush particularly in the beverages.BACKGROUND ART[0002]Supercooling means the phenomenon that a molten object or a solid is not changed although it is cooled to a temperature below the phase transition temperature in an equilibrium state. A material has a stable state at every temperature. If the temperature is slowly changed, the constituent elements of the material can follow the temperature changes, maintaining the stable state at each temperature. However, if the temperature is suddenly changed, since the constituent elements cannot be changed to the stable state at ...
