Abstract
The present invention discloses a non-freezing refrigerator which can keep the contents in a non-frozen state by an electric field. The non-freezing refrigerator includes a setting unit for selecting and setting a magnitude and frequency of a voltage, a generating unit for generating an electric field according to the voltage having the set magnitude and frequency, and applying the electric field to a storing space for storing the contents, and a freezing cycle for cooling the storing space. The contents are kept in the non-frozen state below a phase transition temperature.
Claims18
A non-freezing refrigerator, comprising:
- a casing having a storing space for storing contents, wherein the front portion of the casing is opened;
- a drawer put into or taken out of the front portion of the casing;
- an electrode inserted into a side surface of the casing for generating a set magnitude of energy, and evenly applying the energy to the storing space;
- a load sensing unit for sensing a state of the contents stored in the storing space;
- a microcomputer for setting a magnitude and frequency of a voltage according to an output of the load sensing unit;
- a freezing cycle for cooling the storing space;
- and
- a cool air duct for sucking or discharging the cool air by a freezing cycle formed at the casing,
- whereby the contents are kept in a non-frozen state below a phase transition temperature.
A non-freezing refrigerator, comprising:
- an insulating member having a storing space for storing contents;
- a load sensing unit for sensing a state of the contents;
- a microcomputer for setting a magnitude of a voltage having a radio frequency characteristic according to the state of the contents sensed by the load sensing unit;
- an electrode for generating energy based on the set voltage, and evenly applying the energy to the storing space;
- a freezing cycle for cooling the storing space;
- and
- a cool air duct for sucking or discharging the cool air by a freezing cycle formed at the casing,
- whereby the contents are kept in a non-frozen state below a phase transition temperature.
A non-freezing keeping device, comprising:
- an insulating member having a storing chamber for storing contents;
- an electrode mounted at the side of the insulating member;
- and
- a cool air duct for sucking or discharging the cool air by a freezing cycle formed at the casing,
- wherein the contents or the storing chamber is isolated from edges of the electrode at a predetermined interval.
A non-freezing keeping device, comprising:
- a casing having a storing space for storing contents, wherein the front portion of the casing is opened;
- a drawer put into or taken out of the front portion of the casing;
- an electrode inserted into side surfaces of the casing;
- and
- a cool air duct for sucking or discharging the cool air by a freezing cycle formed at the casing,
- wherein the drawer isolates the contents at the predetermined interval from the electrode and supports the contents.
