         4 . The dish washing machine according to  claim 2 , wherein the lower end of the exhaust duct does not project to an outside of the dish washing machine. 
     
     
         5 . The dish washing machine according to  claim 1 , wherein the exhaust duct further comprises at least one rib formed in the lower end of the exhaust duct and configured to guide a direction of exhausted air flow. 
     
     
         6 . The dish washing machine according to  claim 5 , wherein the at least one rib is sloped to guide air exhausted toward a vertical center line of the door. 
     
     
         7 . The dish washing machine according to  claim 1 , wherein the lower end of the exhaust duct includes a bent portion bent in a direction toward a vertical center line of the door. 
     
     
         8 . The dish washing machine according to  claim 1 , wherein a width of the exhaust duct increase along a downward direction of the exhaust duct. 
     
     
         9 . The dish washing machine according to  claim 8 , wherein a side of the exhaust duct facing a vertical center line of the door is sloped, and an opposite side of the exhaust duct to the side is substantially formed vertically. 
     
     
         10 . The dish washing machine according to  claim 9 , wherein the exhausted duct is further configured to exhaust air toward a direction that the width of the exhaust duct is wider. 
     
     
         11 . The dish washing machine according to  claim 8 , wherein a cross section of an inlet end of the exhaust duct is larger than a cross section of an outlet end of the exhaust duct. 
     
     
         12 . The dish washing machine according to  claim 11 , wherein the exhaust duct includes a water recovering hole communicated with the tub for recovering water in the exhaust duct to the tub,
 a cross section of the exhaust duct comprises at least one step-shape portion stepped in a lower direction, and   an upper surface of the one step shape portion is declined toward the water recovering hole.   
     
     
         13 . A dish washing machine comprising:
 a tub configured to form a space for a dish to be washed;   a door configured to open or close the tub; and   an exhaust duct configured to exhaust air in the tub to an under portion of the door and toward an opening direction of the door.   
     
     
         14 . The dish washing machine according to  claim 13 , wherein the exhaust duct is further configured to exhaust air toward a vertical center line of the door. 
     
     
         15 . The dish washing machine according to  claim 13 , wherein the exhaust duct includes a first bent portion configured to exhaust air in a flow direction toward an opening direction of the door and a second bent portion configured to exhaust the air in an opposite direction to the opening direction of the door. 
     
     
         16 . The dish washing machine according to  claim 15 , wherein the first bent portion is disposed below the second bent portion.
