Defrosting heater, and refrigerator having the defrosting heater
摘要：
A defrosting heater in a refrigerator with a flammable refrigerant sealed therein, including a first glass tube (53) having a heater wire (52) inside thereof, a plug (58) covering both end opening parts of the first glass tube (53) and a second glass tube (54), a lead wire (55) piercing the plug (58) and connected to an end of the heater wire (52), and a positioning plate (57) disposed on a connection part of the lead wire (55) with the heater wire (52). Flame propagation can be prevented by setting the size of a space (58b) formed by the plug (58) and the positioning plate (59) according to the sealing quantity of the flammable refrigerant and the surface temperature of the heater wire (52), and an unstable state in a defrosting mode is prevented even when the flammable refrigerant leaks.
摘要（中）：

在其中密封有可燃性制冷剂的冰箱中的除霜加热器，包括在其内部具有加热线（52）的第一玻璃管（53），覆盖第一玻璃管（53）的两端开口部分的塞子（58）和 第二玻璃管（54），穿过所述插头（5​​8）并连接到所述加热线（52）的端部的引线（55）以及设置在所述引线的连接部分上的定位板（57） 55）与加热线（52）。 可以通过根据可燃性制冷剂的密封量和加热丝（52）的表面温度来设定由插头（58）和定位板（59）形成的空间（58b）的尺寸来防止火焰传播， 并且即使在易燃制冷剂泄漏时也防止除霜模式下的不稳定状态。
