The water supply valve driver 12 for driving the water supply valve under the control of the control unit 10 according to the function selected through the key input unit 11 and the wash water supplied by the water supply valve driver 12 when dewatering can be drained. A drain valve 13 for driving the drain valve, a water level sensing unit 14 for detecting the water level in the washing tank under the control of the control unit 10, and a control signal from the control unit 10 to drive the motor M 1 . It consists of a motor driving unit 15 for proceeding the washing administration, and the buzzer driving unit 16 for notifying the operation state of the washing machine by sound during the washing administration.

이와 같은 구성을 갖는 종래 기술에 따른 세탁기의 섬유유연제 투입방법을 도1 및 도2를 참조하여 설명하면 다음과 같다.The fabric softener input method of the washing machine according to the prior art having such a configuration will be described with reference to FIGS. 1 and 2 as follows.

먼저, 사용자가 키 입력부(11)의 코스선택을 위한 설정키를 한번 누르면 표준코스 LED가 온되고, 설정키를 다시한번 누르게 되면 섬유유연제 LED도 온된다(도2 참조).First, when the user presses the setting key for the course selection of the key input unit 11 once, the standard course LED is turned on, and when the user presses the setting key again, the fabric softener LED is also turned on (see FIG. 2).

이렇게 하여 코스선택과 섬유유연제 선택이 순차적으로 설정되면, 제어부(10)에 선택내용이 기억되고, 그에 따른 수위가 설정된다.When the course selection and the fabric softener selection are set in this way, the selection is stored in the control section 10, and the water level is set accordingly.

이어, 제어부(10)의 제어신호에 따라 급수밸브 구동부(12)가 동작하여 세탁수가 공급되고, 수위가 설정수위까지 도달되면 모터구동부(15)에 의해 모터(M1)가 구동되어 세탁행정을 진행한다.Subsequently, the water supply valve driving unit 12 operates according to the control signal of the controller 10 to supply the washing water, and when the water level reaches the set level, the motor M 1 is driven by the motor driving unit 15 to perform the washing operation. Proceed.

먼저, 세탁행정과 첫번째 헹굼행정은 종래와 동일하게 수행한후 섬유유연제를 투입해야 하는 마지막 헹굼행정이 시작되면 급수밸브 구동부(32)가 온(ON)되어 급수가 시작된다(S100).First, after the washing stroke and the first rinsing stroke is performed in the same manner as in the related art, when the last rinsing stroke to which the fabric softener is to be started is started, the water supply valve driving unit 32 is turned on (ON) and water supply starts (S100).

급수가 되는 동안 수위감지부(34)에 의해 수위가 설정 수위까지 도달하였는지를 계속적으로 감지하여(S101), 수위가 설정수위에 도달하면 급수를 완료하고, 모터구동부(35)를 온시켜 모터(M1)가 회전하여 헹굼을 시작한다(S102).While the water is being supplied, the water level detecting unit 34 continuously detects whether the water level reaches the set water level (S101). When the water level reaches the water level, the water supply is completed, and the motor driving unit 35 is turned on to turn on the motor M. 1 ) rotates to start the rinsing (S102).

그리고, 헹굼이 진행되는 동안 제어부(30)에서 계속 시간을 감지하여 섬유유연제 투입시간(T1)인지를 판단하고(S103), 그 시간(T1)에 도달하면 모터구동부(35)를 오프시켜 모터(M1)의 회전을 중지시킨다.Then, while the rinse is in progress, the control unit 30 continuously detects the time to determine whether the fiber softener input time (T 1 ) (S103), and when the time (T 1 ) is reached to turn off the motor drive unit 35 The rotation of the motor M 1 is stopped.

이어, 배수밸브 구동부(33)가 동작되어 설정수위 보다 한단계 아래 수위까지 배수를 진행한다(S104)(S105).Subsequently, the drain valve driving unit 33 is operated to proceed to the water level one level below the set water level (S104) (S105).

예를들어, 설정수위가 중수위(80ℓ)였다면 저중(74ℓ)수위로 배수를 진행한다(도5 참조).For example, if the set water level is the medium water level (80 L), drainage proceeds to the low medium (74 L) water level (see FIG. 5).

배수가 진행되어 수위가 설정수위 보다 한단계 아래수위에 도달하면 배수를 중지하고 섬유유연제 투입부(36)가 동작되어 유연제밸브(도시않됨)를 일정시간(T2)동안 온시켜 섬유유연제를 투입한다(S106)(S107).When the drainage progresses and the water level reaches one level below the set level, the drainage is stopped and the fabric softener injection unit 36 is operated to turn on the softener valve (not shown) for a predetermined time (T 2 ) to inject the fabric softener. (S106) (S107).

여기서, 유연제 밸브를 온시키는 일정시간(T2)은 세탁기의 수위에 따라 최적의 효과를 나타낼 수 있도록 섬유유연제량이 투입될 수 있는 시간이다(도5 참조).Here, the predetermined time (T 2 ) for turning on the softener valve is the time that the amount of fabric softener can be put in order to exhibit the optimum effect according to the level of the washing machine (see Fig. 5).

유연제 밸브가 일정시간(T2)동안 온되어 일정량의 섬유유연제가 투입되면 유연제 밸브를 오프시킨다(S108).When the softener valve is turned on for a predetermined time T 2 and a predetermined amount of the softener is put in, the softener valve is turned off (S108).

그리고, 마지막 헹굼행정의 남은 시간동안 헹굼을 진행하여(S109), 헹굼행정을 완료한다.Then, rinsing is performed for the remaining time of the last rinsing stroke (S109) to complete the rinsing stroke.

본 발명에 따른 세탁기의 섬유유연제 투입장치 및 방법은 섬유유연제 투입시점의 수위를 감지하여 일정량을 배수하는 행정을 진행하므로 최적의 물량과 그에 따른 최적량의 섬유유연제를 투입하여 유연제 효과를 극대화 시킬수 있다.The fabric softener input device and method of the washing machine according to the present invention detects the water level at the time of the fiber softener input and proceeds the process of draining a predetermined amount, thereby maximizing the softener effect by inputting the optimum amount and the appropriate amount of the softener. .
