METHOD FOR PRE-WASHING OF DISH WASHER

摘要

PURPOSE: A pre-washing method of a dish washer is provided to improve the washing efficiency at an initial washing by melting an appropriate detergent in washing water. CONSTITUTION: A microcomputer(7) contains a door state discriminating unit(71); an initial power on discriminating unit(72); a rinsing water temperature discriminating unit(73); a first water level discriminating unit(74) to discriminate a filling with water; a timer(75); a preparation executing unit(76); and a pre-washing executing unit(77). A detergent of specific amount is melted in washing water by operating a washing pump and a detergent supply motor before a washing stand-by step after finishing a supply of the washing water. Dishes are washed with the washing water melting the detergent. Thereby, the washing efficiency is improved.
