Abstract

Disclosed in this application is a u-shaped grommet for use in a refrigerator. The grommet is fixed so as to allow wires to be routed towards an opening in the liner of the refrigerator, pass through the opening in the liner, and exit the grommet in the opposite direction as the wires entered. The grommet is preferably molded to the wires so that the combined product is inseparable from the wiring which it protects. The grommet is also described as a single piece grommet, although multiple piece grommets are anticipated.

Further disclosed in this application is an improved pass-through hinge for routing utilities, including water and electricity, from the door to the body of the refrigerator. The improved hinge features a hollow hinge pin through which utilities may be routed, thereby overcoming the deficiencies of the current state of the art.

Claims

1. An appliance having a wall or surface comprising:

a grommet for directing one or more elongated utility conduits through an opening in the wall or surface of the appliance, the grommet comprising;

a single piece comprising a mounting body intermediate between conduit guides extending in fixed directions from opposite sides of the mounting body;

a conduit path through the single piece;

the mounting body having a perimeter generally in a plane adapted for mounting in the opening in the wall or surface of the appliance and an interior having a length along an axis through the plane adapted to enclose and route the one or more elongated utility conduits through the mounting body along the conduit path;

each of the conduit guides extending parallel to the plane of the mounting body, and along the opposite sides of the plane of the mounting body in generally the same fixed direction to an end surface and having a perimeter and interior with a length adapted to encircle and route the one or more elongated utility conduits through the conduit guides to and out of said end surface from which the one or more elongated utility conduits can exit from within the grommet substantially perpendicular to the axis through the plane of the mounting body; and

the mounting body comprising a sealing member generally in the plane of the mounting body;

so that the grommet can be inserted through the opening in the wall or surface, and enclose, protect, and route in the fixed direction of the conduit guides the one or more elongated utility conduits to and from the opening in the wall or surface in the appliance, and the one or more elongated utility conduits configured to be positioned substantially parallel to opposite sides of the wall or surface in the appliance.

2. The appliance of claim 1 wherein the perimeter includes a groove for receiving an edge of the opening in the wall or surface of the appliance.

3. The appliance of claim 1 wherein the end surface of at least one of the conduit guides is substantially perpendicular to the perimeter of the mounting body.

4. The appliance of claim 1 wherein the one or more elongated utility conduits comprises a wire or a plurality of wires.

5. The appliance of claim 1 wherein the conduit path comprises a continuous open space through the interiors of the mounting body and conduit guides to encircle and route the one or more utility conduits.

6. The appliance of claim 1 wherein the interiors of the mounting body and conduit guides comprise moldable material adapted to be molded over, encircle and route the one or more utility conduits.

7. A wiring assembly in an appliance, comprising:

a single piece grommet having a mounting portion having a perimeter generally in a plane for installing the grommet through a wall of the appliance, first and second routing portions generally parallel to the plane of the mounting portion and in generally the same fixed direction along opposite sides of the plane of the mounting portion, and wire path sections through the first routing portion, the mounting portion, and the second routing portion, wherein the wire path sections through the routing portions are spaced-apart, fixed, and parallel to each other, and substantially perpendicular to the wire path section of the mounting portion;

a wire entering a face of the first routing portion, following the wire path sections, and exiting a face of the second routing portion; and

the mounting portion comprising a sealing member generally in the plane of the mounting portion.

8. The wiring assembly of claim 7 wherein the grommet comprises moldable material molded onto the wire.

9. The wiring assembly of claim 7 wherein the grommet includes a groove for receiving an edge in the appliance wall.

10. The wiring assembly of claim 7 further comprising one or more additional wires following the wire path sections.
