A cooking appliance includes a housing forming a food handling compartment, a door positioned at the front of the housing that is configured to rotate about a vertical axis, and a hinge assembly secured to the door. The hinge assembly includes a hinge pin extending along the vertical axis and a double slider-crank mechanism that is coupled to the hinge pin. As the door rotates about the vertical axis, the hinge assembly moves the vertical axis along an elliptical path.

1. A home appliance comprising: a housing forming a food handling compartment,a door positioned at the front of the housing, the door being configured to rotate about a vertical axis,a hinge pin secured to the door, the hinge pin being configured to rotate with the door about the vertical axis,a crank arm extending from a first end to a second end, the first end being secured to the hinge pin,a first slider pivotably coupled to the crank arm at the second end, the first slider being constrained to move along a first horizontal axis, anda second slider pivotably coupled to the crank arm between the first end and the second end, the second slider being constrained to move along a second horizontal axis extending perpendicular to the first horizontal axis,wherein as the door rotates about the vertical axis, the crank arm acts on the first slider and the second slider to move the first slider along the first horizontal axis and the second slider along the second horizontal axis such that the vertical axis travels along an elliptical path. 2. The home appliance of claim 1, further comprising a hinge base coupled to the housing, the hinge base having a first guide and a second guide defined in an upper end thereof, wherein: the first guide is transverse to the second guide,the first slider is positioned in the first guide, andthe second slider is positioned in the second guide. 3. The home appliance of claim 2, wherein the first guide and the second guide form a plus-shaped guideway in the hinge base. 4. The home appliance of claim 2, further comprising a cover plate secured to the upper end of the hinge base, the cover plate having a slot defined therein extending parallel to the second horizontal axis, wherein: the crank arm is positioned below the cover plate,the hinge pin extends upwardly through the slot. 5. The home appliance of claim 1, wherein the hinge pin is a hexagonal rod. 6. The home appliance of claim 1, wherein: the crank arm is pivotably coupled to the first slider at a first pivot joint, the first pivot joint having a second vertical axis extending therethrough, andthe crank arm pivots about the second vertical axis as the door rotates about the vertical axis. 7. The home appliance of claim 6, wherein: the crank arm is pivotably coupled to the second slider at a second pivot joint, the second pivot joint having a third vertical axis extending therethrough, andwhen the door is rotated about the vertical axis, the crank arm is pivoted about the third vertical axis such that the first slider is moved along the first horizontal axis and the second slider is moved along the second horizontal axis. 8. The home appliance of claim 1, wherein the housing is a microwave housing, and the food handling compartment is a microwave cooking chamber. 9. The home appliance of claim 1, wherein the housing is a refrigerator housing, and the food handling compartment is a refrigerated storage compartment. 10. A cooking appliance comprising: a housing having a food handling compartment,a door positioned at the front of the housing, the door being configured to rotate about an axis, anda hinge assembly secured to the door, the hinge assembly comprising: a crank arm extending from a first end to a second end, the first end being secured to the door,a first slider pivotably coupled to the crank arm at the second end, anda second slider pivotably coupled to the crank arm between the first end and the second end,wherein as the door rotates about the axis, the crank arm acts on the first slider and the second slider such that the axis travels along an eccentric path. 11. The cooking appliance of claim 10, wherein the crank arm has a hexagonal rod extending from the first end, and the door has a hole defined therein that receives the hexagonal rod. 12. The cooking appliance of claim 10, further comprising: a hinge base coupled to the housing below the door, the hinge base having a first guide and a second guide defined therein, the first guide extending perpendicular to the second guide,the first slider is positioned in the first guide, andthe second slider is positioned in the second guide. 13. The cooking appliance of claim 12, wherein the first slider moves along the first guide and the second slider moves along the second guide as the door rotates about the axis. 14. The cooking appliance of claim 12, wherein the axis is a vertical axis. 15. The cooking appliance of claim 10, wherein the housing is a microwave housing, and the food handling compartment is a microwave cooking chamber. 16. A cooking appliance comprising: a housing forming a food handling compartment,a door positioned at the front of the housing, the door being configured to rotate about a vertical axis, anda hinge assembly secured to the door, the hinge assembly including a hinge pin extending along the vertical axis and a double slider-crank mechanism coupled to the hinge pin,wherein as the door rotates about the vertical axis, the hinge assembly moves the vertical axis along an eccentric path. 17. The cooking appliance of claim 16, wherein the double slider-crank mechanism includes: a crank arm extending from a first end to a second end, the first end being secured to the hinge pin,a first slider pivotably coupled to the crank arm at the second end, the first slider being moveable along a first horizontal axis, anda second slider pivotably coupled to the crank arm between the first end and the second end, the second slider being moveable along a second horizontal axis. 18. The cooking appliance of claim 17, wherein the double slider-crank mechanism includes a hinge base coupled to the housing, and the first slider and the second slider are positioned in a plus-shaped guideway defined in the hinge base.
