Abstract: A control housing for an appliance includes a rear wall and a pair of end caps extending forward from the ends of the rear wall. A control panel assembly extends between the end caps forward of the rear wall. The panel assembly includes a cover plate with a planar body having a perpendicularly projecting rim extending along its top, bottom and ends. The assembly also includes a control mounting plate with a planar body. The mounting plate is shorter than the cover member. The plates are assembled in overlying relationship with the mounting plate positioned within the cover plate rim. A pair of bridging members are connected to the ends of the mounting plate and fit closely within the end portions of the cover plate.

Abstract: An insulated panel for a domestic or household appliance is formed by a process in which two sheets of plastic material are extruded from a co-extrusion die and moved directly into a die thermoforming fixture. When the open die members are closed, the edges of the two sheets are sealed together to form a hollow panel and the walls of the panel are forced outwardly to conform to the shape of the die members. After the hollow panel is trimmed it is moved to a foam machine preferably while still contained in the thermoforming fixture so that foam insulation is inserted into the hollow panel while the walls of the panel are supported by the die members so that these walls are not deformed while the foam insulation is added.

Abstract: A domestic or household appliance is provided which includes a plurality of side panels and a base panel, each of the panels having cooperating integral interlocking means in the edges thereof so that the panels may be manufactured at one location and shipped in knockdown form to another location. The side panels may then be readily assembled on the base panel by unskilled personnel without the use of tools or separate fastening means by simple engagement of the interlocking means in the panel edges. This interlocking means includes a plurality of elongated slots in the base panel which extend inwardly and downwardly at an angle to the vertical and projecting tongues in the bottom edges of the side panels which extend at a similar angle to the vertical and are adapted to be inserted into the slots by movement of the side panel along the angle to the vertical. Cooperating interlocking shoulders on the base panel and the side panels are engaged as the tongues are inserted into the slots.

Abstract: A refrigeration appliance includes a plurality of side panels and a base panel, one of the side panels containing within the inner and outer walls thereof a complete mechanical refrigeration unit. The side panels and the base panel are provided with integral interlocking means in the edges thereof so that the panels may be manufactured at one location and shipped in knockdown form to another location where the side panels may be readily assembled on the base panel by unskilled personnel without the use of tools or separate fastening means by simple engagement of the interlocking means in the panel edges. A lid or closure panel may then be secured to one of the side panels to provide a completely enclosed refrigerated compartment.
