Abstract: PURPOSE: A method for removing frost of a directly freezing type refrigerator is provided to enhance the cooling efficiency by keeping the proper front thickness and to keep the freshness of foods for a long time by decreasing the temperature change of a load. CONSTITUTION: A mechanic frost sensor(10) is operated by the signal of door closing from a sensing switch of door closing. A gear moves a sensing bar(14) up and down by reacting with a rack gear(14a) of the sensing bar(14). Herein, when there is no frost, the sensing bar moves up to the end, and an on/off-protrusion returns to the original position after turning on a bar position sensing switch. Thereby, the existing freezing cycle is continued after judging through the action of the bar position sensing switch that there is no front. On the other hand, when there is frost formed in a certain thickness, the sensing bar is blocked by the frost and is not moved so that the bar position sensing switch is not operated. Accordingly, the frost is removed by operating a heater after stopping the compressor until the frost is reduced into a certain thickness.
