TRANSFORMERLESS DEVICE FOR EVAPORATION OF LIQUID WHEN HEATING Russian patent published in 1999 - IPC

FIELD: medicine, namely disinfection and sterilization. SUBSTANCE: device has heating assembly and reservoir filled with substance evaporating in heating. One end of central member for suction of evaporating substance upwards is inserted in reservoir and in heating assembly. heating assembly is ring-shaped. It is provided with transformless exothermic body. The latter is thermal resistor with positive temperature coefficient of resistance. Its volt-ampere characteristics includes section of at least 100-240 V of applied voltage which satisfies definite condition. Device makes it possible to maintain constant temperature of heat production and constant volume of liquid consumption. EFFECT: enhanced efficiency. 1 tbl, 8 dwg
