The plunger 423 is installed to move forward and backward, and the plunger housing 424 is in communication with the flow path inside the valve housing 421, and the elastic member is installed in the plunger housing 424 to elastically support the plunger 423 ( 425, a diaphragm 426 that moves forward and backward, and selectively opens and closes a flow path inside the valve housing 421, and is fixed to a rear surface of the diaphragm 426 and has a pressure inside the water inlet 421a and an inside of the plunger housing 424. The diaphragm holder 427 moves forward and backward according to the pressure of the diaphragm 426.

이때, 밸브 하우징(421)에는 공급관(41)과 연결되어 외부 급수원으로부터 물을 전달받는 입수부(421a)와 급수관(43)과 연결되어 물을 수조로 전달하는 급수부(421b)가 마련되어 있으며, 플런저 하우징(424)에는 플런저(423)가 진퇴이동하게 설치되며 외부에 솔레노이드(422)가 설치되는 플런저 설치부(424a)와, 다이어프램(426) 및 다이어프램 홀더(427)가 진퇴이동 가능하게 설치되는 다이어프램 설치부(424b)가 마련되어, 다이어프램 설치부(424b)가 입수부(421a) 및 급수부(421b)와 연통되도록 되어 있다. At this time, the valve housing 421 is provided with a water inlet 421a connected to the supply pipe 41 to receive water from an external water source and a water supply 421b connected to the water supply pipe 43 to deliver water to the water tank. In the plunger housing 424, the plunger 423 is installed to move forward and backward, and the plunger installation part 424a, in which the solenoid 422 is installed, and the diaphragm 426 and the diaphragm holder 427 are installed to move forward and backward. The diaphragm attaching part 424b is provided, and the diaphragm attaching part 424b is made to communicate with the acquisition part 421a and the water supply part 421b.

또한, 다이어프램 홀더(427)의 중앙부에는 급수부(421b)의 내부와 플런저 하우징(424)의 내부가 서로 연통될 수 있도록 하는 제 1 연통공(427a)이 마련되어 있으며, 다이어프램(426) 및 다이어프램 홀더(427)의 외곽측에는 입수부(421a) 내부와 플런저 하우징 내부가 서로 연통될 수 있도록 하는 제 2 연통공(427b)이 마련되어 있다. 제 1 연통공(427a)은 플런저(423)가 진퇴이동함에 따라 플런저(423)의 선단에 의해 개폐되어, 제 1 연통공(427a)의 개폐여부에 따라 플런저 하우징(424) 내부의 압력이 변경되도록 되어 있다. In addition, a first communication hole 427a is provided at the central portion of the diaphragm holder 427 so that the inside of the water supply portion 421b and the inside of the plunger housing 424 can communicate with each other, and the diaphragm 426 and the diaphragm holder are provided. On the outer side of 427, a second communication hole 427b is provided so that the inside of the water inlet 421a and the inside of the plunger housing can communicate with each other.

따라서, 탄성부재(425)의 탄성복원력에 의해 플런저(423)가 전진하여 플런저(423)에 의해 제 1 연통공(427a)이 폐쇄되면 플런저 하우징(424) 내부의 압력과 입수부(421a) 내부의 압력이 제 2 연통공(427b)을 통해 균형을 이루게 되므로 다이어프램(426) 및 다이어프램 홀더(427)가 급수부(421b)측으로 전진하며 급수부(421b)를 폐쇄하여 수조(11)로의 물 공급이 중단되며, 솔레노이드(422)에 의해 플런저(423)가 후진하여 제 1 연통공(427a)이 개방되면 플런저 하우징(424) 내부의 물이 제 1 연통공(427a)을 통해 급수부(421b)로 빠져나가 플런저 하우징(424) 내부의 압력이 입수부(421a) 내부의 압력에 비하여 상대적으로 낮아지게 되므로, 압력차에 의해 다이어프램(426) 및 다이어프램 홀더(427)가 후진하면서 입수부(421a)와 급수부(421b)가 플런저 하우징(424)을 통해 서로 연통되어 물이 입수부(421a), 플런저 하우징(424), 급수부(421b)를 차례로 통과하여 수조(11)로 전달될 수 있게 된다. Therefore, when the plunger 423 is advanced by the elastic restoring force of the elastic member 425, and the first communication hole 427a is closed by the plunger 423, the pressure inside the plunger housing 424 and the inside of the water inlet 421a are maintained. Since the pressure of the diaphragm 426 and the diaphragm holder 427 are advanced toward the water supply part 421b, the pressure is balanced through the second communication hole 427b, and the water supply part 421b is closed to supply water to the water tank 11. When the plunger 423 is reversed by the solenoid 422 and the first communication hole 427a is opened, the water inside the plunger housing 424 is supplied to the water supply part 421b through the first communication hole 427a. Since the pressure inside the plunger housing 424 is lower than the pressure inside the water inlet 421a, the diaphragm 426 and the diaphragm holder 427 retreat due to the pressure difference. And the water supply portion 421b communicate with each other through the plunger housing 424 to allow water to enter. Portion (421a), through the plunger housing 424, a water supply portion (421b) in turn is able to be delivered to the tub 11.
