Abstract: A laundry drying system and method in which fresh air flows through a low temperature duct of a preheater, then through a primary heater before entering a laundry drying chamber is described. The air enters into contact with laundry in the chamber, then is exhausted, flowing through a high temperature duct of the preheater. In the preheater, heat pipes transfer heat from the exhaust air in the high temperature duct to the fresh air in the low temperature duct. Thus, heat which would otherwise be discarded in the exhaust air stream is recovered for use in the drying process. The preheater preferably uses heat pipes having a liquid return tube and set in a plate fin heat exchanger. To provide for a cool down cycle, there is a bypass which defeats the operation of the preheater. Lint exhausted by the drying chamber is partly collected by a dry type lint remover between the chamber exhaust and the preheater.

Abstract: An oven door has a movable shield for covering its window during a self-cleaning cycle of an oven. The door includes apparatus for automatically raising and lowering the shield to and from a window covering position as the oven door is raised and lowered, improved track system for controlling and guiding the shield movement within the door and improved locking means for locking the oven door shut only when the shield is in its window covering position.

Abstract: An end cap assembly for an appliance control panel assembly comprises a sheet metal end cap having attached thereto a molded plastic trim plate. The trim plate has an overturned edge to provide a channel which is adapted to receive and envelop exposed edges of the sheet metal end cap. Means is provided for locating the trim plate on the sheet metal end cap in a manner so as to hold the edges of the metal end cap in the corresponding channels of the trim plate.
