Abstract

A control panel assembly of a home appliance enables a planar contact to be made during a thermal fusion of a display panel to a control panel, so that a secure adhesion between the display panel and control panel can be established regardless of design contours of the home appliance. The assembly includes a control panel having a contour according to a design of the home appliance; and a display panel attached to the control panel, wherein a planar contact between the display panel and the control panel is established through a thermal fusion technique. The display panel is provided with a triangular protrusion along rear edge, and the control panel is provided with a recess for receiving the protrusion.

Claims

1. A control panel assembly of a home appliance, the assembly comprising:

a control panel having a contour according to a design of the home appliance; and

a display panel attached to said control panel,

wherein a planar contact between said display panel and said control panel is established through a thermal fusion technique.

2. The assembly as claimed in claim 1, wherein said display panel is provided with a first interlocking means along one edge and said control panel is provided with a second interlocking means for receiving the first interlocking means.

3. The assembly as claimed in claim 2, wherein the first interlocking means of said display panel is a protrusion and the second interlocking means of said control panel is a recess.

4. The assembly as claimed in claim 3, wherein the protrusion and recess each have a triangular cross-section.
