Abstract

본 발명은 의류건조기의 건조제어에 관한 것으로 의류의 종류에 따라 코스를 달리 설정해 줄 필요없이 마이콤에서 포질을 판정하여 그에 적절한 건조제어를 행하게 한 것이다.The present invention relates to the drying control of the clothes dryer, and to determine the quality of the fabric in the microcomputer without having to set the course differently according to the type of clothes to perform the appropriate drying control.

즉, 건조초기에 젖은 의류가 전극센서에 접촉될때마다 나타나는 전압의 크기를 측정하여 그 값의 크기에 따라 의류의 종류를 판별하여 적절한 건조제어를 하는데 일정치 이상의 전압만 카운트하여 그 값이 설정치 이상이면 두껍고 면이 많이 함유된 의류로 판정하여 자동적으로 건조행정을 함으로써 사용자의 실수에 의한 미건조를 막을 수 있는 이점이 있게되고, 의류의 종류에 따른 코스선택이 필요없이 사용자에게 편리함을 제공해준다.That is, by measuring the magnitude of the voltage appearing every time the wet clothing touches the electrode sensor at the beginning of drying, it determines the type of clothing according to the size of the value and performs proper drying control. The back side is determined to be thick and cotton-rich clothing, and the drying operation is automatically performed, thereby preventing the user from drying by mistake, and providing convenience to the user without the need for course selection according to the type of clothing.

Claims

When the wet clothing contacts the electrode sensor 6 in the drum 1, the buffer unit 6-1 buffers and generates a voltage generated at the output voltage V _P from the buffer unit 6-1. The microcomputer that receives the voltage V _H held by the peak-hold part 6-2 that detects and holds the peak value through the analog / digital terminal A / D and outputs the control signal A at regular intervals. And a reset section 6-4 which resets the input of the peak-hold section 6-2 according to the control signal A of the microcomputer 11 and the microcomputer 11. Drying control circuit of the dryer.

After the start of drying, the hold voltage was measured by the electrode sensor at regular intervals, and only the constant voltage was counted. If the counted count is equal to or greater than the set value, it is judged to be thick clothing. If the temperature difference reaches the set temperature difference (△ T), perform a powerful course control routine that ends after a certain period of drying and if the counted number is smaller than the set value, the temperature difference between the drum internal temperature and the dehumidification temperature is set to the set temperature difference (△ T). Drying control method of the clothes dryer, characterized in that for performing a standard control routine to terminate the drying process.
