Abstract

A method for controlling a flocculation washing machine and a flocculation washing machine. A flocculant pre-dissolving device (3) is used when putting a flocculant into a flocculation container (4) of the flocculation washing machine, such that the flocculant has been dissolved when entering the flocculation container. When the flocculation container is being washed, the washing water in a washing tub (8) is injected into the flocculation container through a pipe, and clean water can be selectively injected into the flocculation container through the flocculant pre-dissolving device. In this way, the flocculant and the washing water are mixed more uniformly, with a better flocculation effect and shortened time required for the flocculation reaction, and flocculant powders can be better prevented from remaining in the flocculant pre-dissolving device. When the flocculation container is being washed, the washing water in the washing tub is injected into the flocculation container through the pipe, and the clean water can be selectively injected into the flocculation container by means of the flocculant pre-dissolving device. The flocculation container is flushed twice by means of the washing water and the clean water such that the flocculate and other precipitated residues in the flocculation container can be removed to the utmost, and clean water for cleaning can also be saved.
