Door for washing machine and dryer and washing machine and dryer having the same

A washing machine comprising:

• a housing;
• a tub in the housing for storage of washing water;
• a drum rotatably mounted in the tub for washing laundry;
• a door including:
• a frame having a system for opening/closing an opening provided for introducing the laundry into the drum, and
• a hinge assembly including:
• first and second brackets attached to an inside surface of the housing, the first and second brackets having a hole at an end thereof for pass through engagement with a hinge shaft;
• first and second hinge arms with a first member, the first member having a hole at an end for pass through engagement with the same hinge shaft to be rotatably connected at an end of the first and second brackets;
• a second member extended in succession to the first member and rotatably connected to the frame for being drawn to an outside of the housing, thereby enabling the door to be rotated relative to the first and second brackets and the first and second hinge arms respectively, so as to be opened at an obtuse angle;
• and
• a rib extended from the second member in a direction defined along a rotational axis of the hinge shaft, for reinforcing the strength of the second member,
• wherein the second member is formed of a bar member having a width smaller than the first member and the rib is extended from the bar member, and
• wherein bar member of the second member of the first hinge arm and a bar member of a second member of the second hinge arm are spaced away outwardly from longitudinal center lines of the first members of the first and second hinge arms, and the first hinge arm and the second hinge arm have ribs with widths different from each other.

A dryer comprising:

• a housing;
• a drum rotatably mounted in the housing for drying laundry;
• a heating device mounted in the housing for supplying hot air to the drum;
• and
• a door including:
• a frame having a system for opening/closing an opening provided for introducing the laundry into the drum, and
• a hinge assembly having:
• first and second brackets attached to an inside surface of the housing the first and second brackets having a hole at an end of the first and second brackets for pass through engagement with a hinge shaft;
• first and second hinge arms with a first member, the first member having a hole at an end for pass through engagement with the same hinge shaft to be rotatably connected at an end of the first and second brackets;
• a second member extended in succession to the first member and rotatably connected to the frame for being drawn to an outside of the housing, thereby enabling the door to be rotated relative to the first and second brackets and the first and second hinge arms respectively, so as to be opened at an obtuse angle;
• and
• a rib extended from the second member in a direction defined along a rotational axis of the hinge shaft, for reinforcing the strength of the second member,
• wherein the second member is formed of a bar member having a width smaller than the first member and the rib is extended from the bar member, and
• wherein bar member of the second member of the first hinge arm and a bar member of a second member of the second hinge arm are spaced away outwardly from longitudinal center lines of the first members of the first and second hinge arms, and the first hinge arm and the second hinge arm have ribs with widths different from each other.
