Summary:PROBLEM TO BE SOLVED: To obtain a test burn-in tester(TBT) requiring no drainage facility by a structure wherein a tank for storing melt water of frost on a refrigerator is provided with a heater for evaporating the melt water. SOLUTION: Water level sensors, i.e. water quantity sensors 9A, 9B, are mounted on a tank 8. The sensor 9A is turned on when the water level in the tank 8 reaches level A and the sensor 9B is turned on when the water level in the tank 8 drops down to level B. An SR type FF(flip-flop) 10A is turned on when the sensor 9A delivers an ON signal. Consequently, a relay 10B is turned on to actuate a heater 12 built in an evaporator 11 thus evaporating melt water. When the sensor 9b delivers an ON signal, the FF 10A is turned off and the relay 10B is turned off to interrupt heating of the heater 12. Consequently, water level in the tank 8 is regulated. A fan 11A provided for the evaporator 11 rotates constantly to discharge the steam to the atmosphere.
