Wave wheel of washing machine

Abstract

The invention discloses a wave wheel of a washing machine, comprising a base and a plurality of blades arranged on the base, wherein the blades are provided with veins and water propelling surfaces with slopes at two sides. The wave wheel is characterized in that a cone-shaped platform is arranged at the middle part of the base; raised propelling ribs of which the quantity is same as the quantity of the blades are arranged on the vertical face of the cone-shaped platform and smoothly connected to the corresponding veins; water propelling surfaces of each blade have different slopes; concave surfaces and convex surfaces are arranged on the water propelling surfaces; the veins are S-shaped for corresponding to the curve surface changes of the concave surfaces and convex surfaces of the water propelling surfaces; moreover, side-looking lines of the veins are continuous curves firstly concave and then convex outwards from the center of the base. According to the invention, the blades show a streamline shape like a propeller and the water propelling surfaces are smooth and temperate, but the motive power is strong and the washing ability is outstanding; meanwhile, water flow raised in the middle can be generated to ensure that clothes rotated to the central position of a wash bucket are scattered and effectively prevented from being intertwisted; in addition, the destroy of backward rotation to water flow trend is decreased to ensure that the anti-intertwist ability is further increased.

Description

technical field [0001] The invention relates to a washing machine, in particular to a pulsator with better anti-winding ability for generating water flow. Background technique [0002] A washing machine is a household appliance that uses mechanical energy to drive water to wash clothes. A common fully automatic washing machine with a pulsator contains a washing bucket and a pulsator inside the washing bucket. The pulsator rotates to generate water flow, and the clothes tumble with the water flow in the washing bucket Stir to achieve the purpose of washing. It can be seen that the water flow of the washing machine is very important to the washing ability. According to the change of the water flow, there are various concepts such as "surfing water flow" and "hand rubbing water flow". The essence is the different directions and intensities of the water flow. [0003] Existing fully automatic washing machines generally have the function of positive and negative pulsators, which...
