Abstract: A heating cooker that adjusts cooking operations according to detected cooking states of a food ingredient, and a method thereof are disclosed. The heating cooker includes a heater that heats an inside of a heating chamber in which a food ingredient is placed, and at least one processor that controls the heater to perform a protein denaturation operation, in which a rate of internal temperature rise of the food ingredient is equal to or greater than a reference rate, based on the internal temperature of the food ingredient in a range of from a first reference temperature to a second reference temperature.

Abstract: A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.
