Abstract

An operable panel for an appliance includes a top panel that defines a hinge receptacle. A lid includes a hinge housing. A hinge is disposed within the hinge housing and extends between the lid and the top panel. A retainer includes a cap and a resilient portion. The retainer partially surrounds the hinge and the cap encloses the hinge housing. The resilient portion of the retainer biases the hinge toward the cap and the hinge receptacle.

First claim

What is claimed is:

1. An appliance comprising:
a cabinet having an interior processing chamber;
a lid rotationally operable relative to the cabinet between open and closed positions, the lid having a hinge housing;
a hinge assembly extending between the lid and the cabinet, the hinge assembly comprising:
a hinge member disposed within the hinge housing and having a flange that engages the lid;
a pin that extends outward from the hinge housing to engage the cabinet; and
a retainer that occupies the hinge housing to rotationally secure the hinge member therein, wherein the retainer includes a cap that encloses the hinge housing and also includes a resilient portion that biases the pin through the cap, wherein the retainer includes a body that extends between the ap and the resilient portion, and wherein the body, the cap and the resilient portion are formed as a single unitary piece.

2. The appliance of claim 1 , wherein the resilient portion is defined by a plurality of undulating biasing formations.

3. The appliance of claim 1 , wherein the resilient portion of the retainer is operable between an extended state and a compressed state, wherein the compressed state is defined by the pin of the hinge member being substantially disposed within the retainer.

4. The appliance of claim 1 , wherein the resilient portion of the retainer includes a retaining feature that secures the hinge member against the body.

5. The appliance of claim 1 , wherein the cap includes a fastener that secures the retainer and the hinge member within the hinge housing.

6. The appliance of claim 1 , wherein the retainer is plastic.

7. An operable panel for an appliance, the operable panel comprising:
a top panel that defines a hinge receptacle;
a lid having a hinge housing;
a hinge disposed within the hinge housing and extending between the lid and the top panel;
a retainer having a cap and a resilient portion, wherein the retainer partially surrounds the hinge and the cap encloses the hinge housing, and wherein the resilient portion of the retainer biases the hinge toward the cap and the hinge receptacle, wherein the hinge includes a pin that extends through the cap to engage the hinge receptacle of the top panel, and wherein the hinge includes a flange that partially secures the hinge within the hinge housing, wherein the cap of the retainer engages a first side of the hinge, and the resilient portion engages an opposing second side of the hinge, and wherein the retainer includes a body that extends between the cap and the resilient portion, the body engaging a third side of the hinge, and wherein the body, the resilient portion and the cap are a single integral piece.

8. The operable panel of claim 7 , wherein the resilient portion is defined by a plurality of biasing undulating formations.

9. The operable panel of claim 8 , wherein the resilient portion of the retainer is operable between an extended state and a compressed state, wherein the compressed state is defined by the pin of the hinge being substantially disposed within the retainer.

10. The operable panel of claim 7 , wherein the resilient portion of the retainer includes a retaining feature that secures the hinge against the body, and wherein the cap includes a fastening portion that secures the retainer and the hinge within the hinge housing.

11. The operable panel of claim 10 , wherein the retainer is rotationally secured within the hinge housing and the resilient portion and the hinge are axially operable along a rotational axis of the hinge.

12. A hinge assembly for an appliance, the hinge assembly comprising:
a hinge disposed within a hinge housing of an operable panel;
a retainer having a cap that attaches to an outer aperture of the hinge housing to enclose the hinge housing, wherein the retainer includes a resilient portion that is integrally formed with each of the cap and a body extending between the cap and the resilient portion, wherein the cap engages a first side of the hinge and the resilient portion engages an opposing second side of the hinge, the resilient portion being compressed within the hinge housing and biasing the hinge toward the cap, wherein the body, the resilient portion and the cap are a single integral piece.

13. The hinge assembly of claim 12 , wherein the resilient portion is defined by a plurality of biasing undulating formations that are operable between an extended state and a compressed state, wherein the compressed state is defined by a pin of the hinge being substantially disposed within the retainer.

14. The hinge assembly of claim 12 , wherein the retainer is rotationally secured within the hinge housing and the resilient portion and the hinge are axially operable along a rotational axis of the hinge.
