Abstract
The embodiments herein provide a system for drawing out the racks out of a chamber in a domestic appliance. The system comprises the hooks attached to the respective loop brackets or several steel rods provided with many screws. The hooks are attached to an inner surface of a door of a chamber in a domestic appliance through the brackets that are fixed to the steel rods by the screws or welded to the inner surface of the door. The steel rods are fixed to the door from inside. The hooks are automatically unlatched from the racks when the door is closed. The racks are unlatched due to a pop-up action of the hooks during the closing of the door. The hooks pop-up to the initial position. The hooks pop-up due to a body contact of the hooks with the racks at an upwardly slanting direction.
