<p>The present invention relates to an automatic water level control device to supply water. The present invention significantly reduces maintenance costs of a blocking plate easily damaged by a repetitive opening and closing movement of the automatic water level control device. A cover is coupled to a front surface of a main body to form an inner sealed space, and a water pipe is coupled to an inlet portion formed in a center portion of a rear surface of the main body, and a water supply pipe is coupled to an outlet unit formed in a lower portion. Moreover, the blocking plate provided between the main body and the cover automatically opens and blocks a nozzle inside the main body in accordance with a pressure change of the inside of the main body through the water supply pipe. A recessed groove unit is formed in an opening and closing unit of the center portion, and a watertight member coupled to the groove unit is configured to come in contact with the nozzle.</p> |
