ABSTRACT:
The porthole door has a hinged frame (4) on the housing of the washing machine, consisting of a supporting ring (6) and a retaining ring (8). The supporting ring (6) supports an inspection glass (5) which is recessed in the form of a cup in the direction of the interior of the drum. Said inspection glass is protected by a cover (9) against access at the level of the external retaining ring (8) of the frame (4), the edge thereof being fixed to the frame (4). The cover (9) is made of flat glass cooled by means of a model mould. As a result, the porthole unit is aesthetic and easy to assemble.
