Abstract
A door with a window for an appliance, such as a clothes dryer, and a method for assembling such a door in the appliance are provided. A tempered glass pane may be supported by one or more packaging structures disposed on borders of the glass pane. Each packaging structure may accommodate a retainer. The glass pane may be sandwiched between an inner frame and an outer frame coupled to one another to form a joined assembly effective to tightly seal the borders of the glass pane.
Claims15
A door with a window for a household appliance, the door comprising:
- a) an outer frame to house the window, the outer frame including walls which define a hollow space;
- b) a single tempered glass pane;
- c) an inner frame to further house the window, where said inner frame comprises an inner face and an outer face, a first gutter disposed on the outer face and proximate to the window, a silicon strip having a width ranging from approximately 0.5 cm to approximately 10 cm poured into the first gutter, the tempered glass pane placed over the silicon strip, a second gutter having grooves and disposed on the inner face, a periphery of the second gutter located proximate to an outer periphery of the inner frame, wherein said second gutter receives a first seal affixed to the second gutter by anchors in the grooves, the inner frame further comprising at least two pairs of assembly holes arranged to receive fastening means to form a joined assembly of the inner frame to the outer frame;
- d) at least one plate to support a safety latch, said plate being fastened over an edge of the inner face of the inner frame;
- e) at least one hinge fastened to a border of the assembly of the inner frame and the outer frame, wherein said border is opposite to the edge of the inner face of the inner frame;
- and
- f) a handle including hook-type fasteners received in the hollow space of the outer frame to provide an interference fit to fasten the handle through the walls which define the hollow space of the outer frame,
- wherein the single tempered glass pane and the silicon strip are placed between the outer frame and the inner frame, wherein the hook-type fasteners comprise a first group of fasteners being placed substantially in the same direction towards the door interior and a second group of fasteners being placed on a lower wall of the handle.
