washing machine

Abstract

The present invention provides a washing machine includes a cabinet, a door body, attached to the cabinets of the tub, the tub rotatably positioned in the drum housing, the tub, the laundry out of the drum respectively for loading and unloading port, the door body cylindrical sidewall open or close the loading dock, comprising a drum in the horizontal direction, axially distributed along the drum on the side wall with a plurality of lifting bars, the lifting rib includes a top wall, located on both sides of the curved wall of the longitudinal direction of the top wall , the top wall and the end wall portions at both ends, a top wall, a curved wall, covering end walls together forming a cavity, wherein, in the longitudinal direction of the top wall, and gradually change the degree of bending of the arcuate wall. By the present invention, the lifting rib wall disposed in a state of changing the degree of bend, such a structure can give the washing machine drum at a constant flow guiding action, which can effectively prevent flow "turbulent" state, it tends to " laminar flow "state, thereby reducing the energy consumption of the machine.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a drum washing machine with a lifting rib structure that prevents water flow from forming "turbulent flow". Background technique [0002] The drum washing machine has gradually become the mainstream of the current washing machine market due to its advantages of low water consumption and no wear on clothes. The washing process is designed to imitate the principle of a hammer hitting the clothes. The mechanical work of the motor is used to make the drum rotate. The clothes are repeatedly "lifted" and "dropped" in the drum, and the washing powder and water in the bucket are added. Together, to achieve the washing function of clothes. Wherein, the "lifting" of the clothes is realized by several lifting ribs distributed on the side wall of the drum along the axial direction of the drum. [0003] As we all know, the flow state of liquid can be divided into two states: "laminar flo...

AI Technical Summary

Problems solved by technology

However, in the prior art, during the operation of the inner drum of the washing machine, the water flow in the inner drum is often in a state of "turbulent flow", which causes the "turbulent flow" to bring a large gap between the lifting rib and the water body during the rotation of the drum. Large resistance, which indirectly leads to an increase in the load on the motor that drives the inner drum of the washing machine, which has a negative impact on the overall energy consumption of the washing machine
