1. A latch module for controlling an opening and a closing of a door of an appliance, comprising:
a latch configured to engage with or release from an engaging structure provided on the door;
a cam that contacts a contact surface of the latch; and
an extension having a sub-contact surface protruding from the extension in a direction of the cam,
wherein a cam surface facing the sub-contact surface with a first radius of the cam that contacts the contact surface of the latch has a radius providing a space between the cam surface and the sub-contact surface that allows for the sub-contact surface to approach the cam surface when the latch is moved from the first basic position to the second basic position.
