Refrigerating machine comprising an end-of-defrosting detector
摘要：
A refrigerating machine (10) of the refrigerator or freezer type comprises a device (33) for defrosting cold parts to transform the ice into water to be discharged. It has an end-of-defrosting detector (20) comprising:(1) a reservoir (24) which receives the water to be discharged, one of the branches (23) of a siphon (21) extending into said reservoir in order to drain the reservoir when the water reaches the level required for activation of the siphon, the other branch (22) being situated externally of the reservoir,(2) a light barrier (27, 28), comprising a light source and a light receiver arranged around the other branch (22) of the siphon in such a way that the light beam of the light barrier is interrupted by the passage of water through said other branch while defrosting is in progress, and(3) a electric circuit (30, 31, 32, 34) which stops defrosting when the light beam is not interrupted for a predetermined time.
摘要（中）：

冰箱或冷冻机的冷冻机（10）包括用于对冷部进行除霜以将冰转化为水以排出的装置（33）。 其具有解冻结束检测器（20），其包括：（1）容纳待排出的水的储存器（24），其中一个虹吸管（21）的分支（23）延伸到所述储存器中，以便 当水达到激活虹吸所需的水位时，排出储存器，另一个分支（22）位于储存器的外部，（2）一个光屏障（27,28），包括一个光源和一个光接收器， 围绕虹吸管的另一个分支（22），使得光隔离层的光束在除霜进行期间通过所述另一个分支的水通过而中断，以及（3）电路（30,31 ，32,34），其在光束未被中断预定时间时停止除霜。
