The present invention relates to a thawer, and more specifically, to a thawer using low frequency microwaves to evenly thaws frozen food for a relatively short time, thereby allowing a user to cook the food immediately after thawing the same. The thawer comprises: a frame (10) having an outer portion covered by a cover (11) and having a frame body (10) a thawing chamber (20) having an entry closed by a door (1) installed inside the frame (10) and formed in a housing shape with a microwave inlet passage (21) perforated on one side thereof a waveguide (30) having a microwave generator (35) installed thereon, wherein the microwave generator (35) is fixated to match the inlet passage (21) and an outlet passage (31) in the thawing chamber (20) and provided for the generation and the irradiation of microwaves to the inside the thawing chamber (20) through a control circuit and a perturbation apparatus (40) installed inside the thawing chamber (20) to scatter microwaves and rotated by the operation of a motor (44), wherein the perturbation apparatus (40) is installed in an area where microwaves are inputted. The thawing chamber (20) maintains the ratio (S1) of the volume (V1) divided by the micro-wavelength (&lambda) in the range of 52,000 to 52,100. The waveguide (30) maintains the ratio (S2) of the volume (V2) divided by the micro-wavelength in the range of 1,400 to 1,500. The perturbation apparatus (40) comprises wings (42) formed on both ends of horizontal plates (41) and inclined at a predetermined degree, wherein the horizontal plates (41) are horizontally divided into four directions from the center.COPYRIGHT KIPO 2016본 발명은 해동기에 관한 것으로, 보다 상세하게는 저주파 파이크로 웨이브를 이용하여 냉동된 식품을 빠른 시간안에 골고루 거의 자연 상태로 해동시켜 바로 요리할 수 있도록 발명된 것이다.본 발명은, 커버(11)들에 의해 외부가 감싸지며, 틀체를 형성하는 후레임(10)과, 이 후레임(10)의 내측에서 도어(1)에 의해 입구가 밀폐되고, 마이크로파 유입통로(21)가 일측에 뚫어지는 함체 형상의 해동실(20)과, 상기 해동실(20)의 유입통로(21)와 출구통로(31)가 일치되도록 위치 고정되어 제어 회로에 의해 해동실(20) 내부로 마이크로파 발생 및 조사를 위한 마이크로파 발생기(35)가 안착되는 도파관(30)과, 상기 해동실(20
