Description
제1도는 본 발명의 구김 방지방법이 적용되는 드럼 세탁기의 블럭 구성도1 is a block diagram of a drum washing machine to which the wrinkle prevention method of the present invention is applied.
제2도는 본 발명의 구김 방지방법을 보인 신호 흐름도2 is a signal flow diagram showing a wrinkle prevention method of the present invention
본 발명은 드럼 세탁기의 예약 세탁에 있어서, 건조행정이 완전히 끝난 후 세탁물을 꺼내지 않음에 따라 생기는 구김을 방지하는 드럼 세탁기의 구김 방지방법에 관한 것이다.The present invention relates to a method for preventing wrinkles in a drum washing machine, which prevents wrinkles caused by not removing laundry after a drying operation is completed.
일반적으로 세탁기에는 취침시나 외출시를 위한 예약세탁 기능이 있다.In general, a washing machine has a laundry function for going to bed or going out.
그러므로 사용자가 예약세탁 기능을 선택한 상태에서 코스 및 시간등을 설정해 놓게 되면, 예약시간에서 선택코스에 따라 세탁, 행굼, 탈수, 건조등의 행정이 순차적으로 수행되다가 예약완료시간이 되면 모든 행정을 마치고 종료하게 된다.Therefore, if the user sets the course and time while the reservation laundry function is selected, the administration of washing, rinsing, dehydration, and drying is performed sequentially according to the selected course at the reservation time. Will end.
그런데 드럼 세탁기는 일반 세탁기와는 달리 건조기능이 있으며, 통상적으로 세탁물의 건조는 매우 높은 온도에서 행해지므로 건조후 세탁물을 바로 꺼내지 않으면 구김이 생기게 된다.By the way, the drum washing machine has a drying function, unlike the general washing machine, and the laundry is usually dried at a very high temperature, so if the laundry is not taken out immediately after drying, wrinkles are generated.
즉, 예약세탁 상태에서 긴조행정이 끝나더라도 사용자의 부제등으로 인해 세탁조로 부터 세탁물을 꺼내지 않게 되면, 높은 온도의 세탁조내에서 세탁물이 접힌 상태로 장시간 있게 되므로 세탁물에 구김이 생기게 되고, 이로인해 사용자에게 다람질을 하거나 재손질을 해야하는 등의 불편을 주게되는 문제점이 있었다.In other words, even if the end of the long tank administration in the state of reservation laundry, if you do not take out the laundry from the washing tank due to the user's subtitles, the laundry will be folded in a high temperature washing tank for a long time, causing wrinkles in the laundry, thereby There was a problem that gives the inconvenience, such as having to iron or retouch.
따라서, 본 발명의 목적은 건조후 세탁물을 바로 꺼내지 않아서 생기는 구김을 방지하여 사용자가 세탁물을 다시 손질할 필요가 없게하는 드럼 세탁기의 구김 방지방법을 제공하는데 있다.Accordingly, it is an object of the present invention to provide a method for preventing wrinkles in a drum washing machine, which prevents wrinkles caused by not taking out laundry immediately after drying, thereby preventing the user from having to clean the laundry again.
이와 같은 목적을 가지는 본 발명은 예약세탁 기능을 선택한 상태에서 건조행정이 선택되었을 경우에 예약완료시간이 될때까지 건조히터와 건조팬을 구동시키는 단계와, 예약시간이 경과되면 건조히터 및 팬의 구동을 정지시키고, 도어의 개폐상태를 판별하는 단계와, 도어가 열리지 않았을 경우에 미리 설정된 시간의 경과 여부를 체크하는 단계와, 상기 설정시간이 경과되면 도어의 개폐여부를 체크하면서 세탁모터를 정회전 및 역회전 구동 동작을 반복하는 단계들을 수행하게 된다.The present invention having the above object drives the drying heater and the drying fan until the reservation completion time when the drying operation is selected in the state of selecting the reservation washing function, and the driving of the drying heater and the fan when the reservation time elapses. Stopping the door, determining whether the door is opened or closed, checking whether a predetermined time has elapsed when the door is not opened, and checking whether the door is opened or closed when the set time has elapsed, and rotating the washing motor forward. And repeating the reverse rotation driving operation.

A dry fan driving unit 11 made of a fan motor FM and a microcomputer 1 drive the drain pump DP to control the water used. To be resistance (R 8), consists of a triac (TRA 8), the drain pump to the drain pump (DP) driver (12).
이와 같이 구성된 본 발명의 세탁기는 통상적으로 드럼 세탁기의 동일한 방법으로 동작하며, 예약세탁 기능이 선택되었을 경우에는 후술되는 본 발명의 신호흐름도에 따라 동작하게 된다. 제2도는 본 발명의 구김 방지 방법을 보인 신호흐름도이다.The washing machine of the present invention configured as described above typically operates in the same manner as the drum washing machine, and when the reserved laundry function is selected, it operates according to the signal flow chart of the present invention described later. 2 is a signal flow diagram showing a wrinkle prevention method of the present invention.
먼저, 마이콤(1)은 단계(101)에서 건조행정이 선택되었는지를 판별하고, 건조행정이 선택되었으면 여기서, 마이콤(1)은 그 출력단자(O6)(O7)를 통해 고전위 신호를 출력하며 히터 구동부(10)와 건조팬 구동부(11)의 트라이악(TRA6)(TRA7)을 온시키고, 교류전원(AC)이 트라이악(TRA6)(TRA7)을 통해 건조히터(HT2)와 팬모터(FM)로 인가되므로 건조히터와 팬이 구동하게 된다. 단계(102)에서 건조히터(HT2)와 팬모터(FM)를 구동시켜 세탁물을 건조시킨다.First, the microcomputer 1 determines whether the drying stroke is selected in step 101, and if the drying stroke is selected, the microcomputer 1 outputs a high potential signal through its output terminal O 6 (O 7 ). And outputs the triac TRA 6 (TRA 7 ) of the heater driving unit 10 and the drying fan driving unit 11, and the AC power source AC supplies the drying heater through the triac TRA 6 (TRA 7 ). HT 2 ) and fan motor (FM), so the drying heater and the fan is driven. In step 102, the laundry is dried by driving the drying heater HT 2 and the fan motor FM.
이와 같이 건조행정이 수행되면, 단계(103)에서 현재시간이 미리 설정된 예약완료시간인지를 판별하고, 예약완료시간이 될 때까지 세탁물을 건조시킨다. 예약완료 시간이 되면 단계(104)에서 건조히터(HT2)와 팬모터(FM)의 구동을 정지시켜 건조행정을 종료시키고, 단계(105)에서 도어가 열렸는지를 판별하게 되는데, 이때 상태감지부(4)에서 도어가 열리지 않은것을 판단하게 되면, 단계(106)에서 미리 설정된 소정시간, 예를 들어 30분이 경과하였는지를 판별하고, 30분이 경과되지 않았으면 계속 도어의 개폐를 체크하면서 설정된 시간을 카운트한다.When the drying administration is performed as described above, it is determined in step 103 whether the current time is a preset reservation completion time, and the laundry is dried until the reservation completion time is reached. When the reservation completion time is reached in step 104, the driving of the drying heater HT 2 and the fan motor FM is stopped to terminate the drying administration, and in step 105, it is determined whether the door is opened. If it is determined in step 4 that the door is not opened, it is determined in step 106 whether a predetermined time set in advance, for example, 30 minutes, has elapsed. Count.
이와 같이 건조행정이 완료된 후 도어가 열리지 않은 상태에서 소정시간(30분)이 경과되면, 단계(107)에서 출력단자(O3)(O4)를 통해 구동제어신호를 출력하여 세탁모터 구동부(9)의 트라이악(TRA3)(TRA4)을 수차례 교대로 온 및 오프시키고, 이로인해 세탁모터(MT)는 간헐적으로 정회전 및 역회전하여 구김이 생기지 않도록 세탁조내의 세탁물의 위치를 바꾸어 주게되며, 도어가 열리 때까지 상기 세탁모터(MT)의 간헐 구동 동작을 반복하게 된다.After a predetermined time (30 minutes) has elapsed in the state in which the door is not opened after the drying operation is completed as described above, in step 107, the drive control signal is output through the output terminal O 3 or O 4 to wash the driving motor. 9) Turn on and off the triac TRA 3 (TRA 4 ) several times, which causes the washing motor MT to intermittently rotate forward and reverse to change the position of the laundry in the washing tank so that wrinkles do not occur. The intermittent driving operation of the washing motor MT is repeated until the door is opened.
이상에서와 같이 본 발명은 예약 세탁시 건조행정이 완료된 후 소정시간동안 도어가 열리지 않는 상태가 계속되면 세탁모터를 수차례 정·역 회전시켜 세탁물에 구김이 생기지 않도록 함으로써 사용자가 세탁물을 다림질하거나 재손질해야 하는 번거로움을 해소할 수 있는 효과가 있다.As described above, according to the present invention, if the door is not opened for a predetermined time after the drying administration is completed during the reservation washing, the user may iron or re-wash the laundry by rotating the washing motor several times in order to prevent wrinkles in the laundry. There is an effect that can eliminate the need to care.
