Knob assembly of washing machine, assembly method and washing machine

Abstract

The invention provides a knob assembly of a washing machine, an assembly method, and a washing machine. The knob assembly includes a knob and a light guide ring, and the light guide ring includes an annular connecting ring and a plurality of light guide columns arranged at intervals. A light display window matching the light guide. By providing a light display window matching the light guide column on the knob, the light transmitted by the light guide column is displayed on the knob, and the knob has the function of light display, and there is no need to set the knob decorative plate. During assembly, the process of assembling the knob decorative plate can be reduced, which is conducive to improving assembly efficiency; at the same time, the number of components is reduced, which is conducive to reducing costs; the gap of water seepage on the end surface of the knob assembly is reduced, which is conducive to increasing waterproofness; and a light is provided The display window is conducive to improving the effect of light display and avoiding cross-light and other phenomena.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and in particular relates to a knob assembly of a washing machine, a working method of the knob assembly of the washing machine, and a washing machine with the knob assembly.

[0003] Disadvantages of the existing knob device: first of all, from the appearance, the existing knob device has a single structure and is prone to aesthetic fatigue, but the invention achieves a novel appearance and a unique style through the two-color injection molding of the split knob and the knob cover and the knob cover separated by the aperture ; In terms of cost, the existing structure has a twisted decorative ring, which not only increases the cost, but also has low production efficiency; Clearance with main control board

In addition, the existing knob device is prone to cross-light phenomenon, resulting in display defects
