Abstract

본 발명은 냉장고 또는 냉동기의 증발기에 쌓이게 되는 성에 제거용 히터를 제어시켜 주는 증발기 제상장치에 관한 것으로서, 특히 증발기에 적상된 성에 량에 관계없이 일정시간 동안 제상히터가 작동될때 발생되는 냉각 효율의 저하 현상과 불필요한 전력 소모를 방지하는데 그 목적이 있다.The present invention relates to an evaporator defrosting device that controls a defrosting heater that accumulates in an evaporator of a refrigerator or a freezer, and in particular, a decrease in cooling efficiency generated when the defrost heater is operated for a predetermined time regardless of the amount of frost accumulated in the evaporator. The purpose is to prevent the phenomenon and unnecessary power consumption.

따라서, 증발기(20)의 후방으로 설치된 모터(40)에 의하여 구동되는 냉각팬(30)의 허브에 회전수 변화를 감지하여 주는 센서(31)을 부설하여 초기회전수(N1)과 일정시간 경과후 측정된 회전수(N2)를 비교한 변화 기준치(△N0)에 의해 선택적으로 제상히터(23)를 동작되게 구성하였다.Accordingly, the sensor 31 is installed on the hub of the cooling fan 30 driven by the motor 40 installed to the rear of the evaporator 20 to detect a change in rotational speed. After that, the defrost heater 23 was selectively operated by the change reference value? N0 comparing the measured rotational speed N2.
