KR980000360A - Stroke control device of dishwasher and its control method - Google Patents

Abstract

The present invention relates to an administrative control device and a control method of a dishwasher capable of maximizing a drying effect by opening a door without driving a heater. In order to achieve this object, the present invention comprises a door driving means for opening the door by receiving the control signal of the microcomputer to perform the drying stroke in the stroke control device of the dishwasher equipped with a microcomputer. Therefore, since the natural drying is performed by opening the door without driving the heater, the lifespan of the relay and the control element can be extended, and a blower fan is not required, thereby making the product low-cost.
