Door mechanism of a stock bin of bread maker

A door mechanism suitable for disposing on a bin body of a stock bin of a bread maker, the bin body being configured to temporary receive bread ingredients and having an inner periphery defining an opening, said door mechanism comprising:

• a door panel unit configured to be pivoted to the inner periphery of the bin body to openably close the opening;
• a hinge unit configured to pivotally connect said door panel unit to the inner periphery of the bin body;
• a rotary wheel unit for controlling rotation of said hinge unit;
• a drive unit pivoted between said rotary wheel unit and said hinge unit;
• and
• a motor unit for driving rotation of said rotary wheel unit;
• wherein said door panel unit is movable between a closed position, in which said door panel unit closes the opening in the bin body to prevent the bread ingredients from falling, and an open position, in which said door panel unit exposes the opening in the bin body to permit falling of the bread ingredients from the bin body;
• and
• wherein, when said rotary wheel unit is driven by said motor unit to rotate, said rotary wheel unit drives rotation of said drive unit which in turn drives said hinge unit to rotate said door panel unit to the open or closed position.
