Abstract: A food keeping refrigerator is provided. The food keeping refrigerator keeps food in refrigerating and freezing chambers and refrigerates and freezes the food through a cooling device. The food keeping refrigerator preserves the freshness and nutrition of food for an extended period of time by emitting appropriate light to the food stored in the refrigerating and freezing chambers of the food keeping refrigerator. The food keeping refrigerator includes a storing device that stores food keeping information, a light generating device mounted inside the refrigerating and freezing chambers that generates light and emits the light to the food, and a controller that reads the food keeping information corresponding to the food from the storing device and controls the light generating device to emit the light according to the food keeping information.

Abstract: A storage space variable type refrigerator having a food receiving unit for receiving food thereon, the refrigerator comprising a lifting unit for automatically moving the food receiving unit up and down according to a food capacity. In the refrigerator, a storage efficiency is increased, a loss of cold air generated when the shelf is drawn out with opening a door of the refrigerator in order to store food having a large volume in the refrigerator is prevented, and a user' s convenience is enhanced.

Abstract: The present invention discloses a food keeping refrigerator which can preserve the freshness and nutrition of foods for an extended period of time by emitting appropriate light to the foods stored in storing units. The food keeping refrigerator which keeps foods in a refrigerating chamber and/or a freezing chamber and refrigerates and/or freezes the foods through a cooling unit includes: a storing means for storing food keeping information; a light generating means mounted on the refrigerating chamber and/or the freezing chamber, for generating light and emitting the light to the foods; and a control unit for reading the food keeping information corresponding to the foods from the storing means, and controlling the light generating means to emit the light according to the food keeping information.

Abstract: Object of the present invention is to improve a structure of the air conditioner, to provide an air conditioner which can dispose of condensed water from an evaporator within the air conditioner itself without discharging to outside of the air conditioner, and improve an air conditioner efficiency. To achieve the object of the present invention, the air conditioner of the present invention includes a condenser which generates a high temperature heat, an evaporator which absorbs an external heat, and forms condensed water on a surface thereof by a temperature difference with an external air, and condensed water self disposal means for transferring the condensed water on the surface of the condenser to a condenser side, and evaporating the condensed water from the surface of the condenser by the high temperature heat from the condenser, thereby disposing of the condensed water within the air conditioner itself.

Abstract: A burner for a Stirling engine includes a combustion chamber forming an air-fuel mixture by mixing air and fuel supplied from air inlet passageways and a fuel injection nozzle, an igniter igniting the air-fuel mixture within the combustion chamber, a heater tube absorbing high-temperature heat generated by the combustion of the air-fuel mixture and transferring it to the Stirling engine, and exhaust gas passageways discharging an exhaust gas to the outside. In addition, a heating duct is provided between the combustion chamber and a head portion of the Stirling engine. The heating duct transfers high-temperature combustion gas through combustion gas passageways to the heater tube, thereby increasing a heat transfer rate and preventing corrosion.
