The purpose of the present invention is to provide a device for supplying water to a toilet bowl tank with an anti-counterflow function, which reduces noise by letting water supplied to a tank flow along an outer periphery of an overflow pipe when water from a hydrant is supplied to the tank and a bowl part of a toilet main body through a fill valve mounted on a top part of the overflow pipe, improves productivity and economic efficiency by construction simplification of internal components, and can stably be used by preventing counterflow of water in the bowl part of the toilet main body and water stored in the tank even by counterpressure generated from the hydrant since the fill valve mounted on the top part of the overflow pipe does not communicate with the water stored in the tank. To this end, the device for supplying water to a toilet bowl tank with an anti-counterflow function comprises: the overflow pipe which is mounted on the tank to communicate with the bowl part of the toilet main body; the fill valve which prevents the counterflow of the water in the bowl part of the toilet main body and the water stored in the tank; and a guide member installed on the overflow pipe to guide water flowing along the outer periphery of the overflow pipe. |
