Among them, FIG. 1 is a flowchart of the control method of the drum washing machine of the present invention; FIG. 2 is a schematic structural diagram of the drum washing machine of the present invention.

As shown in FIG. 1 and FIG. 2, in order to solve the problem of poor steam injection effect in the drum washing machine with nursing function in the prior art, the present invention provides a method for controlling the drum washing machine. The drum washing machine mainly includes a cabinet 1 And the outer cylinder 2, the inner cylinder 3 and the water mist generating module 4 provided in the box 1, the inner cylinder 3 is used to accommodate the laundry 6 to be treated, the outer cylinder 2 is used to accommodate the inner cylinder 3, the water mist generating module 4 can Water mist is sprayed into the inner cylinder 3. The control methods mainly include:

S100. Control the inner drum 3 to run at the first set rotation speed, so that the laundry 6 in the inner drum 3 is attached to the inner drum wall, for example, the control unit of the drum washing machine controls the inner drum 3 to rotate at a rotation speed of 100r/min, During the rotation process, the laundry 6 to be treated is attached to the wall of the inner drum to form a cavity in the middle of the inner drum 3, wherein the first set speed is such that the laundry 6 to be treated can be attached to the wall of the inner drum and form a central cavity The first set speed can be obtained based on experiments or can be obtained based on theoretical calculations.
