Abstract: Provided is a defrost heater using a surface heat emission element of a metal thin film having a fast temperature response performance and a low thermal density, to thereby use an environment-friendly refrigerant, and that performs quick temperature rising and cooling during performing a defrost cycle, to thereby quickly restart a refrigeration cycle and thus greatly reduce time required for the defrost cycle, and a fabricating method thereof, and a defrost apparatus using the same. The defrost heater includes: a strip type surface heat emission element made of a strip type metal thin plate; an insulation layer that coats the outer circumference of the strip type surface heat emission element; and a heat transfer board on one side surface of which the surface heat emission element on the outer circumferential surface of which the insulation layer has been coated is installed, and that contacts evaporator fins so that heat generated from the surface heat emission element is transferred to an evaporator.

Abstract: Provided are a magnetic sheet for use in a radio frequency identification (RFID) antenna, an RFID antenna including the magnetic sheet, and a method of manufacturing the magnetic sheet, in which the magnetic sheet includes an amorphous alloy selected from the group consisting of Fe—Si—B, Fe—Si—B—Cu—Nb, Fe—Zr—B and Co—Fe—Si—B. The magnetic sheet is made by laminating amorphous alloy ribbons made of an amorphous alloy between magnetic sheet layers formed of alloy powder including at least one amorphous alloy and then compression-molding the amorphous alloy ribbons, to thereby control microcrack of the amorphous alloy ribbons and enhance characteristic of an end-product. The magnetic sheet is also thin, and has an excellent magnetic permeability, and a simple manufacturing process.

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.

Abstract: The present invention relates to a dryness measuring device, and more particularly the dryness measuring device for sensing a dryness status of laundry in drying. The present invention is to provide an electrode sensor for sensing the dryness status of the laundry and measuring a current dryness status by a variance of a voltage which is charged in capacitor based on a variance of resistance of the electrode sensor. And, the present invention minimizes outside effect by discharging of the charged voltage of the capacitor by designated periods.

Abstract: A dryer control method provides for selection among a plurality of dryness levels so that the user may select a desired degree of dryness for any given type of laundry. The method includes steps of selecting one among a plurality of dryness levels; driving a drying unit holding laundry; sensing a value indicative of a water content of the laundry; comparing the sensed value with first and second predetermined values; measuring a time required for the sensed value to reach the second predetermined value from the first predetermined value; computing a drying time based on the measured time; and stopping the driving step upon expiration of the computed drying time, wherein the first and second predetermined values determine a reference value corresponding to the selected dryness level.

Abstract: An apparatus for controlling gas valves in a gas drier is provided. The apparatus includes an igniter, a closed flame detection switch and a sustaining relay. The igniter, which starts a flame, connects to a first terminal which provides a power signal with respect to a neutral terminal. The closed flame detection switch is connected between the igniter and the neutral terminal thereby receiving the power signal via the igniter. The closed flame detection switch also detects a flame by opening. The sustaining relay provides an alternative path of conduction with respect to the closed flame detection switch.

Abstract: A drier module, for use in a drier having a drier motor and one of two heat generation devices, namely gas or electric, is an interchange module of a drier of a gas or electric type and may be connected to a drier motor and to a gas control circuit of a gas drier or to an electric heater of an electric drier. During drier assembly, the module is adaptively modified, for example, by setting a switch position according to a desired mode, i.e., the intended drier type.
