Abstract

본 발명은 건조 세탁기에서 세탁물의 건조시 감지된 흡입 및 배기 온도차와 습도차를 설정치와 비교, 판단하여 건조 시간을 자동으로 제어할 수 있으므로써 건조편차의 발생을 크게 줄이고, 건조 시간을 단축시켜서 세탁물을 효율적으로 건조시킬 수 있으며, 사용자가 편리하게 사용할 수 있으므로 인해 제품의 효율성 및 신뢰성을 대폭 향상시킨 것이다.The present invention can automatically control the drying time by comparing and judging the difference between the suction and exhaust temperature and the humidity difference detected during drying of the laundry in a dry washing machine to a set value, thereby greatly reducing the occurrence of drying deviation and shortening the drying time. It can be dried efficiently and can be used conveniently by the user, which greatly improves the efficiency and reliability of the product.

이를 위해, 본 발명은 세탁물의 건조시 세탁조(4)내부에 초기 흡입 공기의 온도 및 습도를 검출하여 일정시간이 경과된 후 마이콤의 제어 신호에 의해 남은 시간을 표시하는 단계와, 상기 마이콤의 제어 신호에 따라 건조 행정중 계속 최적의 온도와 습도에 대한 기준값을 읽어 온도차(△T) 및 습도차(△H)를 설정치와 비교하여 판단하는 단계와, 상기 온도차(△T)가 설정온도 이상이고 습도차(△H)가 설정습도 이하이면 히터(11)의 작동을 정지시킨 다음 일정 시간동안 송풍 운전을 할 수행한 후 전 건조 행정을 완료하는 단계를 순차적으로 진행하도록 된 건조 세탁기의 자동 건조 제어방법이다.To this end, the present invention detects the temperature and humidity of the initial suction air in the washing tank (4) during drying of the laundry to display the remaining time by the control signal of the microcomputer after a predetermined time has elapsed, the control of the microcomputer According to the signal, the reference value for the optimum temperature and humidity is continuously read during the drying stroke, and the temperature difference (ΔT) and the humidity difference (ΔH) are compared with the set value, and the temperature difference (ΔT) is greater than or equal to the set temperature. When the humidity difference ΔH is less than the set humidity, the operation of the heater 11 is stopped, and then a blow operation is performed for a predetermined time, and then a step of completing the entire drying stroke is performed. Way.
