In addition, the wash water stored in the detergent storage unit 84 is sprayed to the upper side of the washing tank 54 in accordance with the operation of the pump 90 while passing through the second circulation passage 86 or the third circulation passage 88. As a result of the forced circulation, the detergent is dissolved.

상기와 같이 구성된 본 발명의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

먼저, 사용자가 세제 투입구(52a)에 세제를 투입하고 세탁기에 전원이 인가되면, 제어부(미도시)는 제2급수밸브(74)를 온시켜 일정량의 세탁수를 제1순환유로(82)로 공급한 뒤 상기 제2급수밸브(74)를 오프시키고, 세제와 세탁수는 제1순환유로(82)를 따라 하강하면서 세제액이 되어 세제액 저장부(84)에 저장된다.First, when a user inputs detergent into the detergent inlet 52a and power is applied to the washing machine, the controller (not shown) turns on the second water supply valve 74 to transfer a certain amount of washing water to the first circulation passage 82. After supplying, the second water supply valve 74 is turned off, and the detergent and wash water are lowered along the first circulation passage 82 to form a detergent liquid and stored in the detergent liquid storage unit 84.

그리고, 제어부(미도시)는 세탁물의 포량을 감지하여 일정시간 동안 제1급수밸브(72)를 온시켜 세탁조(54) 내부로 세탁수를 공급하고, 펌프(90)를 역방향으로 구동시켜 세제액이 제3순환유로(88)와 세제액 저장부(84)를 순환하면서 세제를 세탁수에 충분히 용해시킨다.In addition, the controller (not shown) senses the quantity of the laundry, turns on the first water supply valve 72 for a predetermined time, supplies the washing water into the washing tank 54, and drives the pump 90 in the reverse direction to the detergent liquid. The detergent is sufficiently dissolved in the wash water while circulating the third circulation passage 88 and the detergent liquid storage part 84.

이후, 상기 제어부(미도시)는 펌프(90)를 정방향으로 구동시켜 세제액을 제2순환유로(86) 측으로 공급함으로 세제액을 분사노즐(86a)을 통하여 상기 세탁조(54)의 상부에서 분사시킨다.Thereafter, the controller (not shown) drives the pump 90 in the forward direction to supply the detergent liquid to the second circulation passage 86 to inject the detergent liquid from the upper portion of the washing tank 54 through the injection nozzle 86a. Let's do it.

상기와 같이 상기 세탁조(54)에 세탁수와 세제액이 공급되면, 클러치(62) 및 모터(미도시)에 의해 세탁날개(60) 및 세탁조(54)가 선택적으로 정방향 또는 역방향으로 구동되면서 세탁이 진행된다.When the washing water and the detergent solution are supplied to the washing tub 54 as described above, the washing blade 60 and the washing tub 54 are selectively driven by the clutch 62 and the motor (not shown) to be washed in the forward or reverse direction. This is going on.

이와 같이, 세탁 행정이 끝나면 상기 제어부(미도시)는 상기 제1급수밸브(72)를 온시켜 세탁수를 바로 상기 세탁조(54) 내부로 공급하고, 상기 세탁날개(60) 및 세탁조(54)를 회전시키는 헹굼 행정이 진행된다.As such, when the washing stroke is completed, the controller (not shown) turns on the first water supply valve 72 to supply the washing water directly into the washing tank 54, and the washing wing 60 and the washing tank 54. The rinse stroke to rotate is in progress.

또한, 상기 제어부(미도시)가 상기 제2급수밸브(74)도 온시켜 상기 펌프(90)를 정방향으로 구동시킴으로 세탁수가 상기 제2급수밸브(74)를 통해 제1순환유로(82), 세제액 저장부(84), 제2순환유로(86)를 차례로 지나 분사노즐(86a)을 통해 상기 세탁조(54)의 상측에서 분사되어 헹굼 성능을 향상시킨다. In addition, since the control unit (not shown) also turns on the second water supply valve 74 to drive the pump 90 in the forward direction, the wash water passes through the second water supply valve 74 to form the first circulation passage 82, Detergent liquid storage unit 84, the second circulation passage (86) in turn through the injection nozzle (86a) is injected from the upper side of the washing tank 54 to improve the rinsing performance.

상기와 같이, 헹굼 행정이 끝나면, 상기 제어부(미도시)는 배수밸브(미도시)를 온시켜 세탁조(54) 및 탈수조(56)로부터 세탁수를 배수하고, 상기 세탁조(54)를 고속 회전시켜 원심력에 의해 세탁물에 포함된 수분이 상기 세탁조(54)의 배수홀(미도시)을 통하여 빠져나가도록 하는 탈수 행정이 수행된다.As described above, after the rinsing stroke, the control unit (not shown) turns on the drain valve (not shown) to drain the washing water from the washing tank 54 and the dehydrating tank 56, and rotates the washing tank 54 at high speed. Dehydration stroke is performed so that the water contained in the laundry by the centrifugal force is discharged through the drainage hole (not shown) of the washing tank 54.

이와 같이, 원심력에 의해 분리된 수분도 탈수조(56) 하측의 배수밸브(미도시) 및 배수관(미도시)을 통해 배수된다.
In this way, the water separated by the centrifugal force is also drained through the drain valve (not shown) and the drain pipe (not shown) below the dehydration tank 56.

상기와 같이 구성되는 본 발명에 따른 세탁기는 세제를 투입하는 세제 투입 구가 케이스의 상측에 설치되어 있어 사용자가 세제를 투입하기 편리할 뿐 아니라 세탁 행정이 시작되기 이전에 세제용해수단을 따라 세제와 세탁수를 순환시킴으로 세제를 세탁수에 충분히 용해시켜 세탁조 및 탈수조의 상측에서 분사시킴으로 세탁 성능을 향상시킬 수 있는 이점이 있다.In the washing machine according to the present invention configured as described above, the detergent inlet for injecting detergent is installed on the upper side of the case, so that the user is not only convenient to inject the detergent but also the detergent along the detergent dissolving means before the washing stroke starts. By circulating the wash water, the detergent is sufficiently dissolved in the wash water to spray the upper side of the washing tank and the dehydration tank, thereby improving the washing performance.

또한, 헹굼 행정시 세탁수는 세제용해수단을 따라 상기 세탁조 및 탈수조 상측에서 분사되기 때문에 헹굼 성능을 향상시킬 수 있을 뿐 아니라 세탁시간을 단축할 수 있는 이점이 있다. In addition, the washing water during the rinsing stroke is sprayed from the upper side of the washing tank and the dehydrating tank along the detergent dissolving means, so that the rinsing performance can be improved and the washing time can be shortened.
