Abstract
A dampener, and an appliance with a dampener, wherein the dampener provides resistance against the movement of a door of the appliance between an open and closed position. The dampener can be incorporated into the door of the appliance in manner than provides strength for proper operation while also allowing for streamlined aesthetics and less bulk.
Claims10
An appliance defining at least one compartment, the appliance comprising:
- a door attached to the appliance and configured for pivoting movement about an axis of rotation between i) an open position where a user can access the compartment through an opening defined by the appliance and ii) a closed position whereby the door precludes access to the compartment through the opening, the door defining a chamber;
- a bushing positioned adjacent to the chamber of the door;
- at least one dampener received into the chamber and configured for providing resistance against the pivoting movement of the door about the axis of rotation between the open position and the closed position, the dampener comprising
- a dampener housing comprising a first end and a second end that oppose each other along an axial direction parallel to the axis of rotation, the shaft positioned at the first end, the dampener housing defining a pair of opposing, planar walls positioned near the second end, the dampener housing defining a pair of opposing notches, each notch positioned at the second end of the dampener housing within one of the planar walls;
- at least three ribs positioned on an exterior of the dampener housing and extending parallel to the axis of rotation, the three ribs spaced apart from each other about the exterior;
- and
- a shaft extending from the dampener housing and received into the bushing, the shaft rotatable about the axis of rotation.

A dampener for an appliance having a door configured for pivoting movement between an open position and a closed position, the door defining a chamber adjacent to a bushing, the dampener comprising:
- a dampener housing configured for receipt into the chamber, the dampener housing comprises a first end and a second end that oppose each other along an axial direction parallel to the axis of rotation, the rotatable shaft extending from the first end, the dampener housing defining a pair of opposing, planar walls positioned near the second end, the dampener housing defines a pair of opposing notches, each notch positioned at the second end of the dampener housing within one of the planar walls;
- at least three ribs positioned on an exterior of the dampener housing and extending parallel to the axis of rotation, the three ribs spaced apart from each other about the exterior;
- and
- a shaft extending from the dampener housing and configured for receipt into the bushing, the shaft rotatable about the axis of rotation and providing a resistance against such rotation.
1 more element
An appliance, comprising:
- a cabinet that includes at least one compartment;
- a door attached to the appliance and configured for rotating between an open position and a closed position to provide selective access to the compartment, the door having a pair of corners, wherein at each corner the appliance includes a chamber housing defining a chamber therein and includes a dampener assembly, wherein the chamber includes a plurality of grooves extending parallel to the axis of rotation and configured for complementary receipt of the at least three ribs of the dampener, and wherein each dampener assembly comprises:
- a dampener positioned in the chamber, the dampener including a dampener housing,
- at least three ribs positioned on an exterior of the dampener housing and extending parallel to each other, the three ribs spaced apart from each other about the exterior,
- a shaft extending from the dampener and rotatable about an axis of rotation;
- and
- a bushing attached to the cabinet and configured for receipt of the shaft;
- wherein the dampener assembly is configured for providing resistance against rotating movement of the door about the axis of rotation between the open position and the closed position;
- wherein the chamber housing comprises a first end and a second end that oppose each other along an axial direction parallel to the axis of rotation, the rotatable shaft of the dampener positioned at the first end, the dampener housing defining a pair of opposing, planar walls positioned near the second end;
- the dampener housing also defining a pair of opposing notches, each notch positioned at the second end of the dampener housing within one of the planar walls.
