Benefits of technology

[0038]According to the temperature change room of the refrigerator of the present invention, the temperature change room is implemented using the thermoelectric element. Therefore, when it is intended to store the food at a temperature lower than a temperature in a refrigerating chamber, it is not necessary to introduce the cool air of a freezing chamber into the temperature change room. A damper or the like is not necessary, which simplifies the structure of the refrigerator.
[0039]In addition, according to the temperature change room of the refrigerator of the present invention, the heating can be performed in the temperature change room using the thermoelectric element. It is thus not necessary to install two or more evaporators to utilize a heating function.
[0040]Moreover, according to the temperature change room of the refrigerator of the present invention, the temperature in the temperature change room

Problems solved by technology

However, if the temperature is suddenly changed, since the constituent elements cannot be changed into the stable state at each temperature, the constituent elements maintain a stable state at an initial temperature, or some of the constituent elements fail to be changed into a state

first embodiment

[0089]The non-freezing storage unit according to the present invention roughly includes an outer casing 100, a drawer 200 and a side casing 300. The drawer 200 can be inserted into and pulled out of the outer casing 100. As any separate electronic device is not attached to the drawer 200, the drawer 200 can be completely separated and detached from the outer casing 100. The outer casing 100 includes an insulation material 110 to insulate the non-freezing storage unit from the other region of a refrigerator in which the non-freezing storage unit is located. The drawer 200 and the side casing 300 also include insulation materials 210 and 310, respectively. It is thus possible to insulate the portions which are not sufficiently insulated by the insulation material 110 of the outer casing 100. Heaters 140 are installed on the inside of the outer casing 100. A control unit (not shown) adjusts heating values of the heaters 140 to control a temperature in the non-freezing storage unit. The...

second embodiment

[0112]Furthermore, preferably, a sensor 117 measuring a temperature in the non-freezing storage unit 100 and / or a sensor 114 measuring a temperature of food stored in the non-freezing storage unit 100 are installed in the non-freezing storage unit 100. The sensor 114 transfers the sensed temperature information to a control unit (not shown), and the control unit (not shown) controls the direction and intensity of the current applied to the thermoelectric element 111 according to the temperature information sensed by the sensor 114. With respect to the control unit (not shown), a separate control unit (not shown) irrelevant to a refrigerator main body may be provided in the casing 110 or the refrigerator main body to control the functions of the non-freezing storage unit 100, or a control unit (not shown) of the refrigerator main body may serve to control the functions of the non-freezing storage unit 100. The control unit (not shown) can control the functions of the non-freezing sto...

Abstract

The present invention relates to a non-freezing storage unit which can store food at a temperature below 0° C. without freezing the food, and a refrigerator including the same. The non-freezing storage unit includes an outer casing with one open surface, a drawer which can be pulled out and detached through the open surface of the outer casing, a sensor located on one surface of the outer casing and sensing a temperature of food located in the drawer, a thermal conductive member installed on one surface of the drawer facing the sensor and transferring the temperature of the food in the drawer to the sensor, and a heater installed in the outer casing. The non-freezing storage unit is located in a cooling space to store food in a non-frozen state at a temperature below 0° C.

Description

TECHNICAL FIELD[0001]The present invention relates to a non-freezing storage unit which can store food at a temperature below 0° C. without freezing the food, and a refrigerator including the same.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 a 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 into the stable state at each temperature, the constituent elements maintain a stable state at an initial temperature, or some of the constituent elements fail to be changed into a state at a final temperature.[0003]For example, when water is slowly cooled, it is not temporarily fro...
