<p>PROBLEM TO BE SOLVED: To vaporize and discharge drain with a simplified structure. SOLUTION: A drain introduction inlet 2 is provided at an upper portion of a casing 1 comprising a synthetic resin material for introducing drain, and an evaporator 4 is disposed at a bottom of the casing 1 just under the drain introduction inlet 2. On the evaporator 4 there are provided electrode plates comprising a plurality of stainless plates and having a proper area, separated in parallel. Provided any drain is not produced from a cooler and hence drain is prevented from being produced into the casing 1, the electrode plates of the evaporator 4 are insulated to prevent any current from being conducted. However, provided drain is introduced from the drain introduction inlet 2 in the casing 1 and is dropped into the evaporator 4, the drain acts as a conductor among the electrode plates so that the electrode plates serve as a heater to raise temperature and evaporate the drain. When the evaporation of the drain is complete, the electrode plates are again insulated.</p> |
