Description

Background

The impeller can be used in washing machines such as washing machines, clothes dryers or washing and protecting machines, and is usually arranged in a washing chamber, when the impeller is dried, the impeller rotates slowly, and blades on the impeller stir, turn or scatter washings, so that all sides of the washings can be contacted with hot air, and the drying of the washings is accelerated. However, in the washing process, the impeller rotates rapidly, and the laundry is wound on the impeller blades, so that the impeller blades cannot move smoothly, the impeller may stop rotating, and the motor may be burnt out, or the impeller may continue to rotate and the impeller blades may be broken or damaged.

To solve this problem, the current washing machine on the market reduces the twisting phenomenon of the laundry by reducing the number of impeller blades or changing the shape and arrangement of the blades, for example, chinese patent publication No. CN112663287A sets the blades in a staggered manner along the axial direction of the stirring shaft, and makes the projections of two connecting portions formed by two adjacent blades at two connecting positions of the stirring shaft on the axial line of the stirring shaft intersect, thereby preventing the twisting of the laundry. Or, some washing machines do not have blades on the pulsator, so as to reduce the entanglement of the laundry, but only change the position, size, etc. of the water-stirring ribs to enable the washing machines to turn over the laundry, for example, chinese patent No. CN1389618A sets the stirring protrusions on a dish-shaped bottom with a slope on the periphery, and the laundry to be dried rises along the slope by the centrifugal force of the pulsator during the drying process to be turned over.

However, the phenomenon of twisting of the washings cannot be completely avoided by reducing the number of impeller blades or changing the shapes and the arrangement modes of the blades, the washings cannot be well turned over in the drying procedure by changing the positions and the sizes of the water stirring ribs, and the requirements of users on washing and drying cannot be met by the conventional solution.
