Abstract

본 발명은 식기세척 건조기의 세척모터 구동감지 장치 및 방법에 관한 것으로, 전자식 수위센서를 사용하여 다단계로 수위의 변화를 검출하여 세척모터의 구동여부를 확인하여 세척모터가 구동되지 않았을 때의 문제점을 해결하기 위한 식기세척 건조기의 세척모터 구동감지 장치 및 방법을 제공하기 위한 것이다.The present invention relates to a washing motor driving detecting apparatus and method of a dish washing dryer, and detects the change of the water level in multiple stages using an electronic water level sensor to check whether the washing motor is driven to solve the problem when the washing motor is not driven. An object of the present invention is to provide a washing motor driving detecting apparatus and method for a dish washing dryer.

이를 위한 본 발명의 식기세척 건조기의 세척모터 감지장치는 시스템 전체를 제어하는 마이컴과, 상기 시스템 운용에 필요한 전원을 공급하는 전원부와, 상기 시스템 동작진행 상태를 표시하는 표시부와, 상기 마이컴의 제어신호에 의해 각종 부하를 구동하는 부하구동부와, 식기세척 건조기의 터브(TUB)내의 수위변화 상태를 감지하여 변화량에 해당하는 신호를 상기 마이컴으로 출력하는 수위감지부를 포함하여 구성됨을 특징으로 하고 본 발명의 식기세척 건조기의 세척모터 감지방법은 식기세척을 위해 설정된 수위까지 급수를 하는 제1단계, 급수종료후 세척모터의 구동에 의해 수위변화에 따른 주파수를 검출하는 제2단계, 검출된 주파수의 변화유무에 따라 주파수의 변화가 있으면 정상동작을 진행하고, 주파수의 변화가 없으면 모터에러를 감지하여 시스템의 동작을 정지시키고, 에러상태를 디스플레이 하는 제3단계를 포함하여 이루어짐을 특징으로 한다.The washing motor detection apparatus of the dish washing dryer of the present invention for this purpose is a microcomputer for controlling the entire system, a power supply for supplying power for operating the system, a display for displaying the system operation progress state, the control signal of the microcomputer By the load driving unit for driving the various loads by the water level sensor in the tub (TUB) of the dish washing dryer and outputs a signal corresponding to the change amount to the microcomputer, characterized in that it comprises a The washing motor detection method of the dish washing dryer includes a first step of supplying water to a set water level for dish washing, a second step of detecting a frequency according to the water level change by driving the cleaning motor after the completion of water supply, and whether the detected frequency is changed. If there is a change of frequency, normal operation proceeds. If there is no change of frequency, motor error is detected. It characterized by yirueojim to stop the operation of the open system, and a third step of displaying an error condition.
