PROBLEM TO BE SOLVED: To provide a device for detecting and removing frost formed on an evaporator and a method for controlling it.SOLUTION: An evaporator 10 includes: a cooling fin 12 connected to a refrigerant pipe 11 in which a refrigerant circulates and for performing heat exchange; a support bracket 13 for supporting the refrigerant pipe 11; and a defrosting heater 14 for supplying heat for removing the frost formed on the refrigerant pipe 11. A defrosting device 100 for evaporator includes: a light emitting part 120 for radiating light toward the cooling fin 12 provided at one side of the evaporator 10; a sensor part 130 for detecting the amount of light reflected at the cooling fin 12; and a control part (not shown) for controlling ON/OFF of the defrosting heater 14 based on the detected value.SELECTED DRAWING: Figure 6 【課題】蒸発器に着霜した霜を検知して除去する装置とそれを制御する方法を提供する。【解決手段】本発明の一実施形態による蒸発器の除霜装置１００は、冷媒が流動する冷媒管１１に結合されて熱交換を行う冷却フィン１２、冷媒管１１を支持する支持ブラケット１３、及び冷媒管１１に着霜した霜を除去するための熱を供給する除霜ヒータ１４を含む蒸発器１０において、蒸発器１０の一側に設けられた冷却フィン１２に向けて光を照射する発光部１２０と、冷却フィン１２で反射する光の量を検知するセンサ部１３０と、前記検知された値に基づいて除霜ヒータ１４のオン／オフを制御する制御部（図示せず）とを含む。【選択図】図６
