Detailed Description

The invention provides a domestic electric appliance, which comprises an operation panel 3 and a double-color knob 4 arranged on the operation panel 3, and as seen in a combined view of fig. 1 to 5, the double-color knob 4 comprises an inner cover 1 and an outer cover 2, wherein the inner cover 1 is arranged in the outer cover 2, the inner cover 1 is connected with the operation panel 3, part or the whole of the outer cover 2 is of a transparent structure, and the inner wall 201 of the outer cover 2 forms a double-color effect with the transparent structure of the outer cover 2 through surface process treatment.

In the invention, the inner cover 1 is used for installing a double-color knob, the outer cover 2 is used for forming a double-color effect, the inner cover 1 and the outer cover 2 can be separately processed, the inner cover and the outer cover can be assembled together after conventional injection molding with lower cost, and no requirement is imposed on the color of the inner cover 1; simultaneously, the inner cover 1 and the outer cover 2 are mutually independent, the double-color effect is independently presented by the outer cover 2 without being influenced by the inner cover 1, and after the long-term use, the inner wall of the outer cover 2 has the color effect formed by surface process treatment, and is basically not influenced by other matters except oxidation, so that the lasting aesthetic property of the double-color effect can be ensured. The surface processing can be one or more of common processing technologies such as electroplating, spraying, sand blasting, hot stamping, water transfer printing, oil printing, film covering, wire drawing and the like.

For the convenience of assembling the inner cover 1 and the outer cover 2, the outer cover 2 is connected with the inner cover 1 in a buckling manner. The specific buckle connection mode has a plurality of modes, and a linear buckle, a rotary buckle and the like are common. In the embodiment, a linear buckle is adopted, and the inner cover 1 and the outer cover 2 are assembled along the axial direction, so that the knob assembling structure can be suitable for round or other non-round knobs. As shown in the figure, reliably fix in order to realize the axial of inner cup 1 and enclosing cover 2, be equipped with the non return arch 21 at the inside wall of enclosing cover 2, inner cup 1 is equipped with knot body 12, it offsets with the protruding 21 of non return and realizes axial positioning to detain body 12, and simultaneously, reliably fix in order to inner cup 1 and enclosing cover 2 circumference, the both sides that can lie in the protruding 21 of non return on the inside wall of enclosing cover 2 are equipped with positioning groove 22, the both sides that lie in knot body 12 on inner cup 1 are equipped with location arch 13, positioning groove 22 mutually supports and realizes circumferential positioning. It can be understood that, besides the circumferential positioning by the cooperation of the positioning protrusion and the positioning groove, a fastening groove may also be directly formed on the inner side wall of the outer cover 2, and the fastening body 12 cooperates with the fastening groove to realize the circumferential positioning.

It will be appreciated that, instead of a snap-fit connection, the outer cap 2 and the inner cap 1 may be secured by an interference fit connection, or by gluing, or by screwing, etc.

In order to make it clear to the user where the knob is currently rotated, an indication protrusion 14 may be provided on the sidewall of the inner cap 1, and an indication groove 23 matching with the indication protrusion 14 may be provided on the sidewall of the outer cap 2, and the indication protrusion 14 is exposed through the indication groove 23 for the user to observe.
