Abstract
본 발명은 냉장고의 증발기에 관한 것으로서, 특히 증발기의 상부에 착상감지센서를 설치하여 증발기의 효과적인 제상주기를 결정하도록 한 냉장고의 제상주기결정장치 및 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an evaporator of a refrigerator, and more particularly, to an apparatus and method for determining a defrosting cycle of a refrigerator, by installing an idea sensor on the top of the evaporator to determine an effective defrost cycle of the evaporator.
종래에는 증발기에 끼는 성에를 제거하기 위해 증발기의 하부에 제상히터를 두고 일정한 제상주기를 설정하여 규칙적으로 이루어지도록 하였기 때문에 증발기 표면에 성에가 많이 끼지않았을 때에도 작동되게 되어 불필요한 전력소모가 있었고, 이와 반대로 성에가 많이 끼었음에도 불구하고 제상히터가 작동하지 않아 냉각효율을 떨어뜨리게 되는 폐단이 있었다.In order to remove the frost on the evaporator in the past, a defrost heater was placed at the bottom of the evaporator to set a regular defrosting cycle so that it was performed regularly. In spite of the frost, the defrost heater did not work, which lowered the cooling efficiency.
따라서 본 발명은 상기 증발기(12)의 상부에 소정의 간격을 두고 전극(18a)이 설치된 구조의 착상감지센서(18)를 설치하여 증발기의 하부에서부터 발생된 성에가 상승하여 상기 착상감지센서(18)의 전극(18a) 사이로 끼게 되어 미량의 전류가 통전이됨과 동시에 냉동실의 온도를 감지하는 온도감지센서(16)의 온도와 비교하여 15℃ 이상 차이가 나게 되면 이를 제어부에서 이를 인식하여 증발기하부의 제상히터(13)를 작동시키도록 하여 증발기의 성에를 효과적으로 제거하도록 하였다.Therefore, in the present invention, the frost sensor generated from the bottom of the evaporator rises by installing the frost sensor 18 having a structure in which electrodes 18a are installed at predetermined intervals on the evaporator 12, thereby increasing the frost sensor 18. When a small amount of current is energized and a difference of more than 15 ° C. is compared with the temperature of the temperature detecting sensor 16 which detects the temperature of the freezer compartment, the controller recognizes this when the small amount of current is supplied to the electrode 18a. The defrost heater 13 was operated to effectively remove the frost of the evaporator.
