Description

드럼세탁기의 급수장치Feeding device for drum washing machine

본 발명은 드럼세탁기에 관한 것으로서, 특히 세탁조내로의 급수 초기 세제가 세탁조 내로 투입되어 배수구에 침강되는 현상을 방지하도록 하기위한 세탁기의 급수장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drum washing machine, and more particularly, to a water supply device of a washing machine for preventing the initial washing water supply into a washing tank from being settled in the washing tank.

일반적인 종래 드럼세탁기는 도 1 에 도시된 바와 같이 외곽케이스(1)의 내부에는 세탁시 세탁수가 채워지는 터브(2)가 내장되고, 상기 터브(2)의 내부에는 드럼(3)이 장착되며, 상단에는 세탁 및 헹굼시 급수밸브(6)에 의해 세제통(4)으로 물을 급수하는 급수호스(5)와, 세제통(4)으로부터 터브(2) 내부로 물을 급수하는 벨로우즈(7)가 부착되었다.A conventional drum washing machine has a tub (2) inside the outer case (1) is filled with the washing water when washing, as shown in Figure 1, the drum (3) is mounted inside the tub (2), At the upper end, a water supply hose 5 for supplying water to the detergent container 4 by the water supply valve 6 when washing and rinsing, and a bellows 7 for supplying water from the detergent container 4 to the tub 2 are attached. It became.

그리고 상기 터브(2)의 하단에는 배수밸로우즈(8)가 연결되어 있다.And the drainage bellows (8) is connected to the lower end of the tub (2).

이와같이 구성되는 종래 드럼세탁기는 세탁 및 헹굼을 위한 급수모드시 마이컴(도시 생략)에 의해 개/폐되는 급수밸브(6) 및 급수호스(5)를 통하여 세제통(4)으로 급수가 이루어지면, 세제통(4) 내의 세제가 혼입된 세탁수는 계속해서 벨로우즈(15)를 통하여 터브(2)내로 급수가 되어 일정 수위가 되면 급수가 종료되고 세탁 및 헹굼이 이루어진다.The conventional drum washing machine configured as described above is supplied with a detergent container 4 through a water supply valve 6 and a water supply hose 5 opened / closed by a microcomputer (not shown) in a water supply mode for washing and rinsing. The wash water in which the detergent in (4) is mixed is continuously supplied to the tub 2 through the bellows 15, and when the water level reaches a predetermined level, the water supply is terminated and washing and rinsing are performed.

그러나 세제통(4)을 통하여 급수되는 물에 의해 초기부터 세제가 투입되는 종래 기술에서는 세제가 물과 함께 터브(2)내로 흘러 들어가면서 상당량의 세제가 배수구 내의 배수벨로우즈(8)내로 들어가 그대로 침강되게 되는데, 이는 세탁시에도 잘녹지않아 세탁효율을 저감시키고 또, 배수시에는 침강된 상태에서 그대로 배출되어 버림으로 세제를 낭비하게 되는 문제점이 있었다.However, in the prior art in which the detergent is introduced from the beginning by the water supplied through the detergent container 4, the detergent flows into the tub 2 together with the water, and a considerable amount of the detergent enters into the drain bellows 8 in the drain and is settled as it is. This has a problem in that it does not melt well during washing, thereby reducing the washing efficiency and wasting detergent as it is discharged as it is in the settled state.

이런 현상을 방지하기 위하여 배수구 입구쪽에 세제침강을 방지하기 위한 배수밸브(9)를 달기도 하고 순환호스나 물순환펌프를 장착하여 물을 계속 순환시키는 방법을 사용하기도 하지만, 이러한 방법들은 모두 부품이 추가되야 하므로 제품의 제조단가가 상승되고 전체적인 공간을 많이 차지하는등 여러 가지 단점을 가지고 있었다.In order to prevent this phenomenon, a drain valve (9) is installed at the inlet of the drain to prevent sedimentation, and a circulation hose or a water circulation pump is used to continuously circulate the water. Since it has to be added, the manufacturing cost of the product has increased and occupied a lot of the whole space.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 초기 급수모드시는 세제통을 경유하지 않고 곧바로 터브내로 급수가 이루어지도록 하고, 일정 수위가 되면 세제통을 경유하여 세제가 투입 되도록 2개의 급수수단을 구성함으로써, 세탁시 배수구내로 세제가 침강되지 않고 효율적인 세탁이 이루어 지도록 하는 급수장치를 제공하는데 목적이 있다.The present invention was invented to solve the problems of the prior art as described above in the initial water supply mode is to supply water directly into the tub without passing through the detergent container, and when the water level is a certain level through the detergent container 2 By providing two water supply means, it is an object of the present invention to provide a water supply apparatus that allows efficient washing without washing the detergent into the drainage during washing.

본 발명을 첨부도면을 참조하여 이하에서 상세히 설명한다.The present invention will be described in detail below with reference to the accompanying drawings.

먼저 본 발명의 실시예에 의한 구성을 살펴보면 도 2 에 도시된 바와같이 외곽케이스(101)의 내부에는 세탁시 세탁수가 채워지는 터브(102)가 내장되고, 상기 터브(102)내로 세탁수를 급수하기 위한 급수장치로는 초기 급수모드시 샤워밸브(107) 개방에 의해 도어개스캣(108)을 통해 터브(102)내로 물을 급수하는 샤워호스(109)와, 급수밸브(105) 개방에 의해 세제통(104)을 경유해 터브(102) 내로 세탁수를 급수하는 급수호스(106)로 구성되었다. 상기 급수 밸브(105), 세제통(104) 및 터브(102)는 세탁포를 세탁하는 일반적인 세탁 구간(區間)을 구성한다.Looking at the configuration according to an embodiment of the present invention first, as shown in Figure 2, the tub 102 is built in the outer case 101 is filled with the washing water during washing, water supply to the washing water into the tub 102 In order to supply water to the water supply apparatus, the shower hose 109 for supplying water into the tub 102 through the door gasket 108 by opening the shower valve 107 in the initial water supply mode, and by opening the water supply valve 105 It was composed of a water supply hose 106 for supplying the wash water into the tub 102 via the detergent container 104. The water supply valve 105, the detergent container 104 and the tub 102 constitute a general washing section for washing the laundry cloth.

그리고 상기 터브(102)의 하단에는 배수구(110)가 형성되어 있다.In addition, a drain 110 is formed at a lower end of the tub 102.

이와같이 구성되는 본 발명 급수장치의 동작을 도 3 의 제어 블록도를 참조하여 살펴보면 다음과 같다.The operation of the present invention water supply device configured as described above will be described with reference to the control block diagram of FIG. 3.

먼저, 초기 급수모드신호가 입력되면 마이컴(마이크로컴퓨터, 100)에서 샤워밸브(107) 개방신호를 발생하게 되고 급수되는 물은 샤워호스(109)를 따라 도어개스캣(108)을 통해 바로 터브(102)내로 급수된다.First, when the initial water supply mode signal is input, the microcomputer (100) generates a shower valve 107 opening signal, and the water supplied is directly tub (108) through the door gasket 108 along the shower hose (109). 102) into the water supply.

그리고 급수되는 물이 터브(102)내의 일정수위까지 올라오면 터브(102)와 연결된 수위센서(111)가 이를 감지하여 마이컴(100)에 신호를 인가하고, 마이컴(100)은 샤워밸브(107) 폐쇄신호 및 급수밸브(105) 개방신호를 발생시키게 된다.And when the water supplied to the water level in the tub 102, the water level sensor 111 connected to the tub 102 detects this and applies a signal to the microcomputer 100, the microcomputer 100 is the shower valve 107 The closing signal and the open water supply valve 105 are generated.

상기 신호에 의해 급수밸브(105)가 개방되면 샤워밸브(107)를 통한 급수가 중단되고 급수호스(106)를 통해 터브(102) 내로의 급수가 진행되며, 이때 급수되는 물은 세제통(104)을 통과하므로 급수되는 물에 의해 터브(102) 내로 세제가 투입되게 된다.When the water supply valve 105 is opened by the signal, the water supply through the shower valve 107 is stopped and water is supplied into the tub 102 through the water supply hose 106, wherein the water supplied is the detergent container 104. Since the detergent passes through the tub 102 by the water supplied through the through.

이와같은 동작에 의해 터브(102) 내에 일정 수위까지 세탁수가 차게되면 급수밸브(105)가 닫히면서 드럼세탁기의 급수모드가 완료되고 드럼이 회전하면서 세탁모드가 시작되어 세탁물의 안정적인 세탁이 이루어지게 된다.When the washing water fills the tub 102 to a certain level by such an operation, the water supply valve 105 is closed and the water supply mode of the drum washing machine is completed. .

즉, 본 발명에서는 샤워호스(109) 및 샤워밸브(107)를 이용하여 초기급수시에는 세제통(104)으로 급수하지 않고 도어개스캣(108)을 통해 바로 터브(102)내로 급수하되 배수구(110)가 완전히 차고 나면 세제통(104)의 세제가 투입되도록 하므로써 세제가 배수구 속으로 침강되는 현상을 방지할 수 있다.That is, in the present invention, when the initial water supply using the shower hose 109 and the shower valve 107, the water is supplied to the tub 102 directly through the door gasket 108 without being supplied to the detergent container 104, but the drain 110 ) Is completely filled, so that the detergent of the detergent container 104 is injected, it is possible to prevent the detergent from settling into the drain.

상기와 같이 세제침강이 방지되는 이유는 배수구에 이미 물이 가득 채워져 있어 물이 배수구로 흘러 들어가지 못하기 때문에 터브내로 투입되어 터브 바닥으로 떨어진 세제는 드럼의 회전에 의해 쉽게 용해되어 버리므로 배수구내로 침강되지 않고 세탁성능을 더욱 향상시킬 수 있게되는 것이다.The reason why the settling of the detergent is prevented as above is that since the drain is already filled with water so that the water cannot flow into the drain, the detergent dropped into the tub and dropped to the bottom of the tub is easily dissolved by the rotation of the drum. It is possible to further improve the washing performance without settling.

이상 설명한 바와같이 본 발명의 급수장치는 세탁 및 헹굼을 위한 급수모드시 물과 함께 투입되는 세제가 배수구내에 침강되는 것을 방지하여 배수모드시 용해되지 않은 세제가 그대로 배출됨으로 인한 세제낭비를 줄이고 세탁효율을 더욱 향상시킬 수 있도록 하는 효과가 있다.As described above, the water supply device of the present invention prevents the detergent introduced with water in the water supply mode for washing and rinsing to settle in the drain, thereby reducing the waste of detergent due to the undissolved detergent being discharged in the drainage mode and washing efficiency. It is effective to further improve.
