The invention provides a gauze cooking machine capable of keeping water clean, and relates to the technical field of gauze cooking machines. The gauze cooking machine capable of keeping water clean comprises a filtering box; an activated carbon board is movably connected in the filtering box, the activated carbon board comprises an activated carbon board body, and sliding blocks are fixedly installed on both sides of the activated carbon board body; a filtering plate is movably connected in the filtering box, the filtering plate comprises a filtering screen, and a sliding frame is fixedly installed on the filtering screen. According to the gauze cooking machine capable of keeping water clean, through the cooperation of a heating wire, a heat conducting plate, a cooking box, a heat insulating plate, a water pump, a connecting pipe, the filtering box and a water pipe, the heating wire performs heating, the heating conducting plate conducts heat to heat water, the cooking box is providedwith the heat insulating plate, the water pump sucks the water in the cooking box into the filtering box through the connecting pipe, impurities in the water are removed after the water passes throughthe filtering box, the water passes through the water pump and then enters the cooking box through the water pipe, so the water in the cooking box circularly passes through the filtering box, the impurities are filtered out, and the disinfecting and cooking effect is better.
