At this time, the piston 42 disposed on the rear side of the water supply lever 35 receives the force from the water supply lever 35 through the support portion 42c and elastically deforms the elastic member 43 to the inside of the cylinder 41. Move forward.

용기(C)에 적정량의 물이 채워진 후에 도 5에 도시한 바와 같이 사용자가 용기(C)를 급수부(31)에서 꺼내 급수레버(35)에 작용하던 힘이 해제되면 탄성변형되었던 탄성부재(43)가 복원되면서 급수레버(35)를 반대방향으로 회전시킨다. 이에 따라 밸브스위치(34)를 가압하고 있던 가압부(35b)는 밸브스위치(34)로부터 이격되므로 급수밸브(33)의 동작이 정지하여 급수호스(32)는 폐쇄된다. 이와 같이 탄성부재(43)가 복원되는 과정에서 실린더(41) 내로 전진한 상태의 피스톤(42)은 탄성부재(43)에 의해 후진하게 되는데 실린더(41) 내에 배치되어 있는 씰링부(42a)가 후진하면서 급수호스(32)로부터 씰링부(42a)로 물을 흡입한다. 이때, 외부 급수원과 연결되어 있는 급수밸브(33) 흡입측 유로는 급수밸브(33)에 의해 폐쇄되어 있는 상태이므로 실린더(41) 내에는 급수밸브(33)의 배출측 유로에 남아있던 물이 흡수된다. 따라서, 급수호스(32)의 배출측 유로에 남아있던 물의 대부분이 실린더(41)에 흡입되어 급수호스(32)에 남아있는 물이 급수부(31)로 낙하하는 현상은 대폭 저감된다. After the container C is filled with the appropriate amount of water, as shown in FIG. 5, when the user removes the container C from the water supply part 31 and the force applied to the water supply lever 35 is released, the elastic member that has been elastically deformed ( 43) is rotated to rotate the water supply lever 35 in the opposite direction. As a result, since the pressurizing part 35b that pressurizes the valve switch 34 is spaced apart from the valve switch 34, the operation of the water supply valve 33 is stopped and the water supply hose 32 is closed. In this way, the piston 42 in the state advanced into the cylinder 41 in the process of restoring the elastic member 43 is reversed by the elastic member 43, the sealing portion 42a disposed in the cylinder 41 is Water is sucked in from the water supply hose 32 to the sealing portion 42a while reversing. At this time, since the intake side flow path of the water supply valve 33 connected to the external water source is closed by the water supply valve 33, water remaining in the discharge side flow path of the water supply valve 33 is stored in the cylinder 41. Is absorbed. Therefore, the phenomenon that most of the water remaining in the discharge side flow path of the water supply hose 32 is sucked into the cylinder 41 and the water remaining in the water supply hose 32 falls to the water supply part 31 is greatly reduced.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 냉장고는 급수호스에 남아있는 물을 흡입하는 잔수흡입장치가 구비되어 물의 배출이 완료된 후 급수호스에 남아있는 물을 잔수흡입장치가 흡입하도록 되어 있으므로 급수호스의 배출측 유로에 남아있는 물의 양이 대폭 줄어들게 되어 급수호스에 남아있는 물이 급수부로 낙하하는 현상은 저감되게 되는 작용효과가 있다.As described above in detail, the refrigerator according to the present invention is provided with a residual water suction device for sucking water remaining in the water supply hose, so that the residual water suction device sucks water remaining in the water supply hose after the discharge of water is completed. The amount of water remaining in the discharge side flow path of the water is greatly reduced, so that the water remaining in the water supply hose falls into the water supply part is reduced.
