   要想弄清这个问题，首先要弄清电冰箱的工作原理，下面就压缩式冰箱介绍一下。 压缩式电冰箱是电机压缩式电冰箱的简称，它主要有以下三个构成部分：箱体、制冷系统与控制系统。而其中最关键的是制冷系统。 现在就来看看制冷系统是如何工作的。它是利用物态变化过程中的吸热现象，使之气液循环，不断地吸热和放热，以达到制冷的目的。其具体过程是：通电后压缩机工作，将蒸发器内已吸热的低压、低温气态制冷剂吸入，经压缩后，形成温度为55℃～58℃，压强为1128帕的高压、高温蒸气，进入冷凝器。由于毛细管的节流，使压力急剧降低。因蒸发器内压力 低于冷凝器压力，液态制冷剂就立即沸腾蒸发，吸收箱内的热量变成低压、低温的蒸气。再次被压缩机吸入。如此不断循环，将冰箱内部热量不断的转移到箱外。正是因为这样，所以夏天用冰箱来冷却房间，不但是不可能的，反而会使其内部温度升高。 通过以上分析，我们知道只要压缩机一工作，其机体内就有高压存在，并且在断电后，要有段时间才能消失，这就是冰箱为什么不能在关机后立即开机的原因所在。下面详细分析一下其内在机理。 电冰箱在运行过程中，其制冷系统压缩机的吸气侧移为低压侧，其压力略高于大气压力。压缩机的排压侧移为高压侧，压强高达117007帕左右，两侧的压强差很大(压力差也是很大)，停机后两侧系统仍然保持这个压力差，如果立即起动，压缩机活塞压力加大，电机的压动力矩不能克服这样的压力差，使电机不能起动，处于堵转状态，这就使得旋转磁场相对于转子的转速加快，磁通量的变化率加大了，从而导致电机绕组的电流剧增，温度升高，如果时间长，很有可能烧毁电机。因此要求停机后过4<SPAN style="FONT-SIZE: 12pt; FONT-FAMILY: 宋体; mso-ascii-font-family: 'Times New Roman'; mso-hansi-font-family: 'Times New Roman'; mso-font-kerning: 1.0pt; mso-ansi-language: EN-US; mso-fareast-language: ZH-CN; </SoftIntro><SoftIntroEncode>
