Household appliance with fingerprint sensor
Abstract:
The present invention relates to a household appliance (10) such as an oven, a refrigerator, or a washing machine. The household appliance comprises a transparent casing element (12) and a fingerprint sensor (20) mounted to the inside of an exterior surface of said casing element (12). The sensor comprises a light source (21; 21′; 21″; 21′″) emitting light for which said casing element (12) is transparent, a detector (23; 23″; 23′″) for detecting reflected light emitted from said light source (21; 21′; 21″; 21′″) and a light guiding means (22; 22′; 22″; 22′″; 22b′″) for guiding emitted light from said light source (21; 21′; 21″; 21′″) towards the casing element (12) and guiding light reflected at the exterior surface of the casing element (12) to the detector (23; 23″; 23′″). Thereby detection of a fingerprint image through said casing element (12) is rendered possible.
Abstract(Chinese):

家用电器（10）技术领域本发明涉及一种家用电器（10），例如烤箱，冰箱或洗衣机。 家用电器包括透明壳体元件（12）和安装到所述壳体元件（12）的外表面内部的指纹传感器（20）。 所述传感器包括发射所述壳体元件（12）透明的光的光源（21; 21'; 21“; 21”），用于检测从所述壳体元件（12）透射的反射光的检测器（23; 23“; 23” 所述光源（21; 21'; 21“; 21”“）和用于引导来自所述光源（21; 21'）的发射光的导光装置（22; 22'; 22”; 22“ '; 21“; 21”“）朝向壳体元件（12）引导，并将在壳体元件（12）的外表面反射的光引导到检测器（23; 23”; 23“”）。 从而可以通过所述壳体元件（12）检测指纹图像。
