Abstract

본 발명은 식기 세척기의 건조시간 제어시스템이 관한 것으로, 일반적인 식기 세척기는 마이콤에 설정된 몇가지 종류의 건조시간을 선택하여 사용하게 되어 있어 건조진행중 식기의 건조에 관계없이 설정된 시간만큼 건조가 진행되므로 식기의 미 건조 및 과다 건조등의 비효율적 건조가 진행되는 문제점이 있었다.The present invention relates to a drying time control system of a dishwasher, and a general dishwasher is to select and use several kinds of drying time set in the microcomputer, so that drying proceeds for a set time regardless of drying of the dishes during the drying process. There was a problem that inefficient drying such as undrying and overdrying proceeds.

본 발명은 건조진행중 세척실태의 습도를 습도감지부를 통해 현습도를 감지하여 설정습도와 비교하는 제1수단과, 상기 설정습도 이상이면 현온도를 감지하여 설정된 히터오프온도와 비교하는 제2수단과, 상기 결과가 히터오프온도이면 히터와 송풍팬을 오프시킨후 다시 현온도와 설정된 히터구동온도를 비교하여 결과가 히터구동온도이면 히터와 송풍팬을 온시키는 제3수단과, 상기 제1수단에서 설정습도 이하이면 히터와 송풍팬을 오프시켜 식기의 건조용 완료하는 제4수단으로 이루어짐으로써 건조를 효율적으로 할수 있다.The present invention provides a first means for detecting the humidity of the washing conditions during the drying process through the humidity detection unit to compare the set humidity with a second means for detecting the current temperature and the set heater off temperature if the set humidity is more than; A third means for turning off the heater and the blower fan if the result is the heater off temperature and then comparing the current temperature with the set heater drive temperature and turning on the heater and the blower fan if the result is the heater drive temperature; When the humidity is below the set humidity, the heater and the blower fan are turned off, and the fourth means for completing drying of the tableware can be dried efficiently.

Claims

A microcomputer (1) for controlling the drying of the dishes by driving the load driving unit according to the key signal of the key input unit includes a humidity sensing unit (10) for sensing and inputting the humidity change in the washing chamber irrespective of the change in the ambient temperature in the washing chamber. Drying time control system of dishwasher.

The method of claim 1, wherein the microcomputer (1) is a first means for detecting the humidity in the washing room during the drying process by detecting the humidity humidity through the humidity detection unit 10 and compared with the set humidity, and the result of the comparison is more than the set humidity The second means for sensing the current temperature of the washing state and comparing it with the set heater off temperature, and if the compared result is the heater off temperature, the heater and the blower fan are turned off, and then the current temperature and the set heater driving temperature are compared again. If the result of the comparison is a heater driving temperature, the third means for turning on the heater and the blower fan, and if the result compared with the first means is below the set humidity, the fourth means for turning off the heater and the blower fan to complete drying of the dishes. Drying time control system of the dishwasher, characterized in that made.

The humidity sensor (10) of claim 1, wherein the humidity sensing unit (10) connects one end of the resistors (R1) and R2 to a common power supply terminal (Vcc), and the other end of the resistors (R1) and (R2) is connected to a humidity sensor ( RH) and one end of the temperature sensor RT are connected to the output ports P1 and P2 of the microcomputer 1, and the other ends of the humidity sensor RH and the temperature sensor RT are connected in common. Drying time control system of the dishwasher, characterized in that connected to the input port (AO) of 1).
