Abstract: Provided is a catalyst converter for purifying exhaust gas and a method for manufacturing the catalyst converter, in which a heater is disposed between inner/outer monoliths, to thereby heighten a heat transfer efficiency and induce a uniform catalytic reaction, and to thereby enhance a processing performance, and minimize an electric power consumption and miniaturize a device. The catalyst converter includes: a heater having a winding portion which is wound so as to have a space therein and a pair of electric power terminals; inner and outer monoliths which are inserted in the inner and outer circumferential portions of the heater winding portion wherein each of the inner and outer monoliths includes a number of hollow cells on the surfaces of which catalysts have been coated and which are formed in the lengthy direction; and a housing in which a support assembly is assembled.

Abstract: Provided is a drying heater, a heating unit for drying laundry using the same, a drying control system and control method thereof that reduces electric power consumption of the drying heater to supply high temperature dry air to the inside of a drum in a washing machine or a laundry drying machine, to thus simplify structure of the drying heater and reduce a manufacturing cost. The drying control method includes the step of applying a first electric power from a first drive power supply to a drying heater when a drum internal temperature is lower than a preset temperature, and applying a second electric power from a second drive power supply which is relatively smaller than the first electric power to the drying heater when the drum internal temperature is higher than the preset temperature. The drying heater includes a surface-shaped heat generation member made of a low thermal density strip style metal thin plate.
