Referring to fig. 1-3, a drum of a drum washing machine includes an inner tub 1, a flange shaft 102 is disposed on an inner side wall of the inner tub 1, three lifting ribs 101 are circumferentially arranged at an end portion of the flange shaft 102, which is close to the inner tub 1, the other side of the lifting ribs 101 is abutted against the inner tub 1, the flange shaft 102 and the inner tub 1 rotate together at a high speed, and clothes are subjected to centrifugal force in the inner tub 1, so that water on the clothes is thrown out.
Referring to fig. 4 and 5, a fixed object 103 is disposed in one lifting rib 101, the three lifting ribs 101 divide the inner tub 1 into three parts equally, the lifting rib 101 where the fixed object 103 is located is used as a starting point, the area surrounded by the three lifting ribs 101 is divided into a first area a, a second area b and a third area c along the clockwise direction, and the mass of the fixed object 103 is determined according to the dehydration procedure of the drum washing machine, that is, the absolute value of the difference between the eccentric mass of the clothes and the mass of the fixed object is as high as possible within the allowable high-speed dehydration eccentric range of the drum washing machine.
Referring to fig. 6, a method for controlling drying of a drum washing machine is characterized by comprising the steps of:
step one, putting clothes into an inner barrel 1; detecting resultant force of the eccentric center crossing of the clothes and the fixed object 103;
judging whether the resultant force passing through the center of a circle exceeds the eccentric range value of the high-speed rotating speed, preferably, the eccentric range value of the high-speed rotating speed is 400g-600g, if not, carrying out high-speed spin-drying, and if so, executing the third step;
judging whether the clothes are positioned in a first area a or a third area c, namely, the adjacent area of the lifting rib 101 where the fixed object 103 is positioned, if so, correcting eccentricity of the clothes to a second area b through rotation of the inner barrel 1, namely, the opposite area of the lifting rib 101 where the fixed object 103 is positioned, detecting resultant force of circle centers again, and executing step four, if not, carrying out low-speed spin-drying;
judging whether the resultant force passing through the center of a circle exceeds the eccentric range value of the high-speed rotating speed, wherein the resultant force passing through the center of a circle is the absolute value of the difference between the eccentric force of clothes and the eccentric force of a fixed object passing through the center of a circle, preferably, the eccentric range value of the high-speed rotating speed is 400g-600g, if not, the high-speed rotating dehydration is performed, and if yes, the low-speed rotating dehydration is performed.
In this way, the washing machine corrects the eccentric times at most three times, so that the dewatering time is well saved, and in addition, the water content in clothes can be obviously reduced: according to the conventional method, when the washing machine dewaters at a low speed, clothes are possibly sprayed by water when being taken out, and the water content is about 100%; in this way the washing machine will generally dewater at a high speed, i.e. the final laundry will have less water content, about 60%.
