Abstract
A refrigerator comprising a fan to operate for supplying cold air to a cooling chamber; an RF output device disposed in the cooling chamber, and for outputting an RF signal into a cavity in the cooling chamber; and a controller for controlling the RF output device, wherein the controller is configured to output the RF signal to goods in the cavity, and to operate in a first section in which temperature of the goods falls, and a second section in which the temperature of the increases after the first section and maintains, wherein when the RF output device operates, a temperature of the cavity is higher than a temperature of other area in the cooling chamber. Accordingly, the freshness of the goods in the refrigerator can be maintained by using the RF signal.
Claims20
A refrigerator comprising:
- a compressor for compressing refrigerant;
- an evaporator for performing heat exchange using the refrigerant compressed by the compressor;
- a fan to operate for supplying cold air generated by the heat exchange in the evaporator to a cooling chamber;
- an RF output device disposed in the cooling chamber, and for outputting an RF signal into a cavity in the cooling chamber;
- and
- a controller for controlling the RF output device,
- wherein the controller is configured to output the RF signal to goods in the cavity, and to operate in a first period in which a temperature of the goods falls, and a second period in which the temperature of the goods increases after the first period and maintains,
- wherein when the RF output device operates, a temperature of the cavity is higher than a temperature of other area in the cooling chamber,
- wherein the controller is configured to:
- output a RF signal of a first power during a scan period,
- determine a type of the goods based on a reflected RF signal during the scan period, and output an RF signal of a second power set based on the determined type of the goods after end of the scan period.
A refrigerator comprising:
- a compressor for compressing refrigerant;
- an evaporator for performing heat exchange using the refrigerant compressed by the compressor;
- a fan to operate for supplying cold air generated by the heat exchange in the evaporator to a cooling chamber;
- an RF output device disposed in the cooling chamber, and for outputting an RF signal into a cavity;
- and
- a controller for controlling the RF output device,
- wherein the controller is configured to control to output the RF signal, in a state where the cooling chamber or a door of the cavity is closed, when a temperature of the cooling chamber is lower than or equal to a first temperature, and the temperature in the cavity is lower than or equal to a second temperature higher than the first temperature,
- wherein the controller is configured to:
- output a RF signal of a first power during a scan period,
- determine a type of the goods based on a reflected RF signal during the scan period, and output an RF signal of a second power set based on the determined type of the goods after end of the scan period.
