摘　　要：早期生产的上菱牌电冰箱，其化霜定时器多采用机械定时控制，使用至今，机械磨损或内电动机异常，均会造成定时不准或不定时．如果采用市面上大量销售的“冰箱／冰柜延时保护节能温度控制器”进行改装，来代替间冷式电冰箱化霜定时器，完全实现电子定时控温，可靠性高且价格低廉．The defrost timer of Shangling refrigerator works by means of mechanical timing--control. When used for a certain period of time, its mechanical attrition or malfunction of its inner motor may lead to inaccurate timing or timing failure. Replacement of such an out--of--order timer with an energy--saving temperature controller available on the market will not only turn the fridge into an electronic timing appliance but also improve its function.
