Outer drum cover of washing machine, washing machine and control method

Abstract

The invention discloses an outer drum cover of a washing machine, the washing machine and a control method. The outer drum cover of the washing machine is provided with an annular cavity, a water inlet is formed in the periphery of the annular cavity and located in an outer drum, and after lifted along the inner wall of the outer drum of the washing machine, water flow enters the annular cavity through the water inlet and is sprayed into an inner drum. According to the outer drum cover, it can be achieved that the water flow is lifted along the inner wall of the outer drum of the washing machine and sprayed into the inner drum without additionally arranging a water pump and increasing the power of a motor; moreover, the water flow entering the annular cavity can be prevented from being affected by the rotation of the inner drum and a balance ring, so that the water flow is smoother, the dispersion of the water flow is good, spraying is conducted more evenly, and the spraying effect is better.

Description

technical field [0001] The invention belongs to the field of washing machines, and in particular relates to an outer bucket cover of a washing machine, a washing machine and a control method. Background technique [0002] At present, washing machines with a spraying function are generally provided with a circulating water pump, through which the water at the bottom of the outer tub is drawn to the upper outer tub cover for spraying. However, installing a circulating water pump not only increases the cost, but also increases power consumption when used, wasting resources and energy. [0003] The eddy current washing machine does not need to be equipped with a circulating water pump. During washing, the motor drives the pulsator and the inner tub to rotate, and then drives the water flow to rotate. Under the centrifugal force generated by the high-speed rotation, the water flow can be lifted along the inner and outer tubs to reach When the outer barrel is covered, it is block...

AI Technical Summary

Problems solved by technology

Or even if there is a water dividing rib on the outer barrel cover, the direction of the water flow is not considered, and the diversion effect is not good. It is also necessary to increase the motor power to achieve a better spray cleaning effect, resulting in a waste of resources

[0005] In addition, the outer bucket cover with water-guiding ribs on the lower end is directly installed on the upper part of the outer bucket and extends to the balance ring to spray into the inner bucket. The shape of the water flow will be affected during the rotation of the inner bucket and the balance ring, which is not conducive to water flow. Flow along the diversion ribs, affecting the spray effect
