Abstract
A home appliance having a door which may be opened and closed, and more particularly, a home appliance to assist a user in easily opening or closing a door is disclosed. The home appliance includes a cabinet having a chamber in which an object is received or retrieved, a door to open or close the chamber, and a handle assembly to be rotated relative to the door during opening or closing of the door, wherein rotation of the handle assembly causes the door to be rotated about a door rotating axis.
Claims25
A home appliance comprising:
- a cabinet having a chamber in which an object is received or retrieved;
- a door to open or close the chamber, the door having a communication aperture;
- a handle rotated relative to the door during opening or closing of the door, wherein rotation of the handle causes the door to rotate about a door rotating axis;
- and
- a link unit connected to the handle, the link unit transmitting a rotation angle or rotation force of the door to the handle in accordance with rotation of the door,
- wherein the link unit comprises:
- a handle link to rotate along with the handle;
- and
- a link unit rotating axis defining a rotation center about which the handle link is rotated, and
- wherein a length of the handle link outwardly exposed from a front surface of the door through the communication aperture increases as an opening angle of the door increases.
7 more elements
A home appliance comprising;
- a door rotatable about a door rotating axis;
- a handle rotatably provided in front of the door to assist a user in opening or closing the door;
- a link unit connected to the handle and rotatable about a link connector rotating axis to transmit a rotation angle of the door to a rotation angle of the handle, the link connector rotating axis being spaced apart from the door rotating axis,
- wherein the link unit includes:
- a handle link to rotate about a link rotating axis inside the door as the door is rotated, the handle link serving to rotate the handle about the link rotating axis, and
- a link connector having a first end to be rotated about the link connector rotating axis and a second end to rotate the handle link as the door is rotated;
- wherein a length of the handle link outwardly exposed from a front panel of the door increases as an opening angle of the door increases.
4 more elements
A home appliance comprising:
- a cabinet having a chamber in which an object is received or retrieved;
- a door to open or close the chamber while being rotated about a door rotating axis;
- a handle at one side of the door;
- a handle link connected to the handle and having a link rotating axis inside of the door so as to rotate the handle about the link rotating axis;
- a link connector connected to a link node of the handle link to rotate the handle link as the link connector is rotated about a link connector rotating axis;
- a first bracket on the cabinet to form the door rotating axis;
- and
- a second bracket on the cabinet to form the link connector rotating axis, the link connector rotating axis spaced apart from the door rotating axis,
- wherein the handle link is rotated by a difference between a rotation radius of the link node with respect to the door rotating axis and a rotation radius of the link node with respect to the link connector rotating axis as the door is rotated.
