HEAT STORAGE TUB FOR PREVENTING HEAT LOSS

摘要

PURPOSE: A heat storage tub for preventing heat loss is provided to restrain the hat loss of the heat storage tub by using an overflow pipe when an internal pressure thereof is lowered. CONSTITUTION: A heat storage tub for preventing heat loss includes a heater part(11) mounted at a lower part of the heat storage tub(10) for heating a liquid in the tub, and an overflow pipe(20) closely contacting the inner wall of the tub to be fixed. The overflow pipe has a suction hole(21) positioned in the center of the ceiling of the tub and a discharge hole(22) positioned at a side of a lower end of the tub. The suction hole is inclined downward with an inclination angle of 40-50°. By the overflow pipe, only pressure is discharged out of the tub but the heat remains in the tub for sufficient heat exchange.
