[0002] The existing dye vats have unreasonable ways of heating the dye liquid. Generally, a heating tube is set at the bottom of the dye vat. However, this structure easily causes uneven temperature of the liquid in the dye vat, which easily leads to color spots. Moreover, in the existing garment dyeing machines, when the drum in the dye vat rolls, the heat in the dye vat will be lost through the gap between the dye vat shell and the outer cover door. The more the drum rolls, the more serious the heat energy loss is, and the temperature fluctuation of the liquid in the dye vat is large, which also causes the problem of uneven dyeing. In the existing dyeing machines, the design of the dye liquid adding window is unreasonable. After the dye liquid is added, it cannot be evenly mixed with the water in the dye vat in time, which easily leads to the problem of uneven dyeing. Summary of the invention
