First embodiment
As shown in fig. 1 to 3, the washing machine drum comprises a drum body 100, wherein a plurality of conical bosses 110 are distributed on the inner wall of the drum body 100, the height of each conical boss 110 is 1-3 mm, four through holes 120 are uniformly arranged on the circumferential direction of each conical boss 110 at intervals, and the diameter of the bottom surface of each conical boss 110 is larger than that of each through hole 120.
Through setting up toper boss 110, effectively increased the frictional force to the washings under the washing operation, and then strengthened the washing cleanliness factor. In addition, during the spin-drying operation, the conical boss 110 can support the washings, so that the washings are prevented from being attached to the inner wall of the barrel 100 during the spin-drying operation, and the phenomenon of thread hanging damage is further prevented. The washings comprise fabrics such as clothes, towels and the like.
The tapered boss 110 includes a bottom surface disposed on the inner wall of the cylinder 100, and a top surface opposite to the bottom surface. The height of the tapered boss 110 refers to the distance between the bottom and top surfaces. In this embodiment, the height of the tapered boss 110 is 1-3 mm, which can effectively increase the friction force to the laundry and prevent the laundry from sticking to the inner wall of the barrel 100. Preferably, the height of the tapered boss 110 is 2 mm.
Referring to fig. 2, the bottom surface of the tapered boss 110 is circular, the through-hole 120 is also circular, and the diameter of the bottom surface of the tapered boss 110 is greater than that of the through-hole 120.
The diameter of the bottom surface of the conical boss 110 is 7-11 mm, and the diameter of the through hole 120 is 2.5-5 mm. Wherein the diameter of the tapered boss 110 is 2 to 3 times the diameter of the through-hole 120.
Preferably, the diameter of the bottom surface of the tapered boss 110 is 9mm, and the diameter of the through hole 120 is 3.5 mm.
In one embodiment, the top surface of the tapered boss 110 is curved, see FIG. 3. The top surface of the cone-shaped boss 110 is prevented from being too sharp to damage the washing.
In another embodiment, the top surface of the tapered boss 110 is horizontal.
With continued reference to fig. 2, the plurality of conical bosses 110 are arranged in multiple layers along the axial direction of the cylinder 100, the plurality of conical bosses 110 in each layer are arranged at intervals along the circumferential direction of the cylinder 100, and two adjacent layers of conical bosses 110 are arranged in a staggered manner;
a through hole 120 is arranged between two adjacent conical bosses 110 of each layer.
By adopting the structure, the arrangement of the conical bosses 110 and the through holes 120 is more compact, so that the number of the through holes 120 is correspondingly increased, the penetrating power of the detergent and water in the barrel 100 in the washing operation is improved, and the water content of the washed objects in the spin-drying operation can be effectively reduced.
Specifically, the tapered bosses located on the upper layer are arranged between two adjacent tapered bosses located on the lower layer, so that the adjacent two layers of tapered bosses 110 are arranged in a staggered manner.
Referring to fig. 2, the distance between two adjacent layers of tapered bosses 110 can be calculated using the following formula:
wherein d is the distance between two adjacent layers of the conical bosses 110;
a is the diameter of the bottom surface of the conical boss 110;
