The present invention relates to a water supply apparatus for sanitary ware. In accordance with the present invention, a vertical pipe body is formed in an upper part of a water supply hole, wherein housings having water discharge holes are provided on both sides of the water supply hole, and, an upper part of the vertical pipe body is sealed with a finishing cap, wherein a motor is installed on an upper side of the finishing cap, and a height adjustment part with an adjustable length is provided in the vertical pipe body, a lifting opening/closing part is formed in a lower part of the height adjustment part to insert a flow rate controller into the water supply hole or separate the controller therefrom, and opening/closing devices are formed on upper sides of the water discharge hole, and, accordingly, as the lifting opening/closing part is lifted and moved through the height adjustment part in accordance with a supply amount of water introduced into the water supply hole, the flow rate controller is inserted into the water supply hole or separated therefrom to control the amount of water discharged in a direction to the water discharge hole through the flow rate controller. In accordance with the present invention, as the water is led through the flow rate controller or the water is lead through a gap between a flow path and the flow rate controller separated from the water supply hole, a fixed amount of water can be discharged through the water discharge holes, and, also, the flow rate controller is inserted into the water supply hole or separated therefrom in accordance with a change of the supply amount of the water introduced into the water supply hole during the operation, to easily control the discharge amount of the water, and, in particular, as the pressure of the water is controlled in proportion to the discharge amount of the water discharged through the water discharge holes, the water discharged to a rim pipe flows down along the inner circumference surface of a ball part, and then, collides with the inner circumference surface of the ball part, thereby preventing water spattering.

본 발명은 위생도기용 급수장치에 관한 것으로, 물공급홀 상부에 수직관체를 형성하되, 물공급홀 양측에 물배출홀을 형성한 하우징을 구비하고, 수직관체 상부를 마감캡으로 밀폐하되, 이 마감캡 상면에 모터를 설치하며, 수직관체 내에 길이가 조절되는 높이조절부를 구비하고, 높이조절부 하부에 유량조절기를 물공급홀에 진입 또는 이격시키는 승강개폐부를 형성하며, 물배출홀 상측에 개폐장치를 형성함으로써, 물공급홀로 유입되는 물의 공급량에 따라 높이조절부로 승강개폐부를 승강 이동시키면서 유량조절기를 물공급홀로 진입시키거나 또는 물공급홀에서 이격시켜, 물배출홀 방향으로 배출되는 물의 배출량을 유량조절기로 조절한다. 본 발명에 따르면, 유량조절기로 물을 통과시키거나 혹은 물공급홀에서 이탈된 유량조절기와 유로 사이의 틈새로 물이 그대로 통과되도록 하여 물배출홀로 정해진 량의 물이 배출되도록 조절할 수 있고, 또한, 사용도중 물공급홀로 유입되는 물의 공급량 변화에 따라 유량조절기를 물공급홀로 진입시키거나 혹은 이탈시켜 물 배출량을 손쉽게 조절할 수 있으며, 특히, 물배출홀로 배출되는 물의 배출량에 비례하도록 물의 수압이 조절되어, 림배관으로 배출되는 물이 볼부 내주면을 따라 흘러 내려가 볼부 내주면에 물이 충돌되면서 물 튀김 현상이 발생되는 것이 방지된다.
