Abstract
A porthole door for a front-loading laundry appliance includes a door glass, a frame and a centering device. The door glass is curved inward toward an inside of the appliance. The frame includes an inner ring and a cover ring. The centering device is disposed on the frame and configured to bear resiliently against a peripheral edge of the door glass so as to provide a radial force acting on the door glass via the peripheral edge at various locations. The radial force brings the door glass into a centered position within the frame.

A porthole door for a front-loading laundry appliance, the porthole door comprising:
- a door glass curved inward toward an inside of the appliance;
- a frame including an inner ring and a cover ring;
- a centering device disposed on the frame and including a plurality of first resilient elements, the first resilient elements configured such that the centering device bears resiliently against a peripheral edge of the door glass so as to provide a radial force acting on the door glass via the peripheral edge at various locations so as to bring the door glass into a substantially centered position within the frame;
- an observation window covering a curved portion of the door glass;
- and
- an additional centering device disposed on the frame and including a plurality of second resilient elements, the second resilient elements configured such that the additional centering device bears resiliently against a peripheral edge of the observation window so as to bring the observation window into a substantially centered position within the frame.
