Abstract
A door closure device includes a pivot pin adapted to engage an associated appliance hinge, and a channel rotatably connected to the pivot pin and adapted to be connected to an associated appliance door. A cam is non-rotatably engaged with the pivot pin. The cam comprises a lobed edge including a closing portion. A spring rod is slidably engaged with the channel, and a cam follower is operably engaged with the spring rod. A spring is engaged between the spring rod and the channel and biases the cam follower into engagement with the lobed edge of the cam. The follower moves along the lobed edge of the cam when the channel is rotated relative to the cam and the spring induces a door-closing torque on the channel when the follower is engaged with the closing portion of the cam lobed edge.
