PURPOSE: A chip filter of washing water capable of automatic backwashing is provided to automatically perform backwashing in an opposite direction from a purification direction of a filter by sensing filter clogging using a pressure sensor. CONSTITUTION: A chip filter of washing water capable of automatic backwashing includes a cylindrical receiving body (100). The receive body comprises a dirty tank (700), a clean tank (800), a fluid pump(600), first and second three way automatic opening and closing valves (500, 510), first and second two way automatic opening and closing valves (520, 530), a pressure sensing member (300), and a filter (200). If pressure rises in the receiving body because of clogging phenomenon of a filter hole in the filter is generated, the pressure sensor inside the pressure sensing member senses the risen pressure, and the controller compares the risen pressure with the pre-set value. If the risen pressure is higher than the set value, the automatic opening and closing valves are operated by the electric signals of the pressure sensing member and the backwashing process is performed. |
