Claims (3)
- 냉각실(10)의 증발기(20)에 착상된 성에를 제거하기 위하여 제상히터(30)의 작동을 제어부가 판단하여 제어하는 제상시스템에 있어서, 상기 증발기(20)에 대향하는 면을 제외한 그 전체가 외부와 단열되며 격벽(67)에 의해 분리된 2개의 격실(66a)966b)을 형성하여 각각 제어부와 전기적으로 연결된 써모커플(77)(88)을 설치하고, 상기 격실(66a)(66b)중 어느 하나에는 외기가 출입가능하게 관통공(74)이 형성되어 증발기(20) 인접위치에 설치된 제상센서(60)를 구비하여, 제어부에서 판단된 상기 써모커플(77)(88)의 온도차가 3 ℃ 이하일 때에만 제상히터를 가동토록 구성된 것을 특징으로 하는 냉장고의 제상시스템.
- 제1항에 있어서, 상기 제상센서(60)는 증발기(20)로부터 약 5∼10㎚ 이격 설치되는 것을 특징으로 하는 냉장고의 제상시스템.
- 제1항에 있어서, 상기 제상센서(60)는 두랄루민인 것을 특징으로 하는 냉장고의 제상시스템.
