다음은 본 발명의 일 실시 예에 의한 드럼세탁기의 중앙 물 분사 장치의 동작에 대해서 설명한다.Next will be described the operation of the central water jet device of the drum washing machine according to an embodiment of the present invention.

먼저, 도시되지 않은 구동수단이 동작되어 구동축(50)이 회전하면 상기 구동축(50)에 설치된 내조(60)가 회전하여 세탁을 행하고, 상기 내조(60)의 내측에 설치된 봉부재(81)역시 함께 회전한다.First, when the driving means (not shown) is operated to rotate the drive shaft 50, the inner tub 60 installed on the drive shaft 50 is rotated to wash the rod member 81 installed inside the tub 60. Rotate together.

그러면, 펌프(110)가 동작되어 물을 펌핑 시키고, 상기 펌핑된 물은 급수호스(120)를 따라 이송되어 구동축(50)의 내측에 형성된 유로(51)를 따라 이송되어 봉부재(81)의 내측에 형성된 유로(81a)를 따라 유입되고, 상기 봉부재(81)의 내측에 유입된 물은 수압에 의해 다수의 분사홀(81b)을 통해 내조(60)의 내측으로 분사된다. 이때, 홀더부재(130)는 급수호스(120)를 통해 공급되는 물이 회전하는 구동축(50)의 내측에 형성된 유로(51)를 통해 공급될 수 있도록 연결관 역할을 한다.Then, the pump 110 is operated to pump the water, and the pumped water is transported along the water supply hose 120 to be transported along the flow path 51 formed inside the drive shaft 50 so that the rod member 81 The water flows in along the flow path 81a formed inside, and the water flows into the rod member 81 is injected into the inner tub 60 through the plurality of injection holes 81b by hydraulic pressure. At this time, the holder member 130 serves as a connector so that the water supplied through the water supply hose 120 can be supplied through the flow path 51 formed on the inside of the drive shaft 50 to rotate.

상기 분사홀(81b)을 통해 분사되는 물은 내조(60)의 회전력에는 상관 없이 펌프(110)의 펌핑력에 의해 즉 단순히 수압에 의해 물이 분사된다.The water injected through the injection hole 81b is injected by the pumping force of the pump 110, that is, simply by water pressure irrespective of the rotational force of the inner tank 60.

상기 다수의 분사홀(81a)을 통해 내조(60)의 중앙측에서 분사된 세탁수는 세탁물 전체에 고른 압력 및 밀도로 분사됨에 따라 세탁물의 세탁효과를 더욱더 높이고, 또한 물 사용량이 줄어들게 된다.Washing water sprayed from the central side of the inner tank 60 through the plurality of injection holes (81a) is sprayed at a uniform pressure and density throughout the laundry to further increase the washing effect of the laundry, and also reduce the water usage.

상기에 있어서, 상기 봉부재(81)가 내조(60)의 중앙측에 길게 설치되는 것을 예로 들어 설명하였으나, 그에 한정된 것은 아니며, 도 4에 도시한 바와 같이 비세탁시에는 탄성부재(201)의 복원력에 의해 접혀져 있다가 수압이 걸리면 상기 탄성부재(201)가 늘어남과 동시에 접혀 있던 봉부재(81)가 앞으로 전진하는 형태로 구현하여 세탁물의 출입을 용이하게 하도록 할 수도 있다.In the above, the rod member 81 has been described as an example that is installed in the central side of the inner tub 60 as an example, but is not limited to this, as shown in Figure 4 when the non-washing of the elastic member 201 When folded by the restoring force and the hydraulic pressure is applied, the elastic member 201 may be increased and at the same time, the folded rod member 81 may be implemented to move forward.

또한, 상기에 있어서, 물 분사 동작이 수압에 의해 분사되는 것을 예로 들어 설명하였으나, 그에 한정된 것은 아니며, 용량이 작은 펌프를 사용하고, 내조의 회전속도를 증가 시켜 원심력에 의해 물이 분사되도록 할 수도 있다. 이때, 내조의 회전속도를 증가시키는 것은 구동수단에 의한다.In addition, in the above, the water injection operation has been described as an example in which the injection by the water pressure, but is not limited thereto, using a small capacity pump, it is also possible to increase the rotational speed of the inner tank so that the water is injected by the centrifugal force have. At this time, increasing the rotational speed of the inner tank is by the drive means.

상술한 바와 같은 본 발명에 의한 드럼세탁기의 중앙 물 분사 장치에 의하면, 내조의 중앙에서 물이 분사되도록 함에 따라 세탁물에 세탁수가 고른 압력과밀도로 세탁물 전체에 고르게 분사되도록 하여 세탁효과를 높임은 물론 세탁수가 세탁물에 고르게 흡수되도록 함에 따라 물 사용량을 줄일 수 있는 이점이 있고, 또한 가시적인 효과도 높일 수 있는 이점이 있다.According to the central water spraying device of the drum washing machine according to the present invention as described above, as the water is injected from the center of the inner tank to ensure that the washing water is evenly sprayed throughout the laundry at a uniform pressure and density to the laundry to enhance the washing effect as well as As the washing water is evenly absorbed by the laundry, there is an advantage of reducing the amount of water used, and also has an advantage of increasing the visible effect.
