Title:
REFRIGERATOR
Document Type and Number:
WIPO Patent Application WO/2020/255245
Kind Code:
A1
Abstract:
This refrigerator comprises a door and an operation panel that is provided in the door and displays an operation icon. The operation panel has a transparent plate member, a sheet that is provided on the rear side of the transparent plate member and detects a capacitance that changes when the operation icon is operated, a substrate which is provided on the rear side of the sheet and on which a light-emitting source for emitting light to the sheet is mounted, and a control unit that receives the capacitance detected by the sheet as an operation signal and controls the on/off of the light-emitting source. The sheet has a transparent conductive member that detects a capacitance, pattern wiring that transmits the capacitance detected by the transparent conductive member to the control unit, a light-shielding layer that has a display pattern for displaying the shape of the operation icon, and a light-diffusing layer that is provided on the light-emitting-source side of the light-shielding layer and diffuses the light emitted from the light-emitting source. The region of the sheet where the pattern wiring is provided is a first light-shielding-layer-free region where a light-shielding layer is not provided.
