Abstract

A dishwasher includes a tub, a blower fan configured to blow air into the tub, and a blower duct configured to guide air blown by the blower fan to flow. The blower duct includes an inlet and an outlet. The dishwasher includes an outlet cap to cover the outlet, and configured to guide a direction of the air discharged through the outlet, the outlet cap comprising a first outlet cap and a second outlet cap. The outlet includes a first outlet and a second outlet spaced apart from the first outlet. The blower duct further includes an outlet cap coupling portion configured to guide the first outlet cap to a first seating position where the first outlet cap is coupled to the first outlet and to guide the second outlet cap to a second seating position where the outlet cap is coupled to the second outlet.

What is claimed is: 
     
         1 . A dishwasher, comprising:
 a tub;   a blower fan configured to blow air;   a blower duct configured to guide the air blown by the blower fan to flow therethrough, the blower duct including:
 an inlet through which the air enters; and 
 an outlet through which the air discharges; and 
   an outlet cap to cover the outlet, and configured to guide a direction of the air discharged through the outlet, the outlet cap comprising a first outlet cap and a second outlet cap,   wherein the outlet comprises:
 a first outlet; and 
 a second outlet spaced apart from the first outlet, and 
   the blower duct further comprises:
 an outlet cap coupling portion configured to guide the first outlet cap to a first seating position where the first outlet cap is coupled to the first outlet, and to guide the second outlet cap to a second seating position where the second outlet cap is coupled to the second outlet. 
   
     
     
         2 . The dishwasher of  claim 1 , wherein the outlet cap coupling portion comprises a guide protrusion protruding toward the outlet cap to guide the first outlet cap to the first seating position and to guide the second outlet cap to the second seating position of the outlet cap. 
     
     
         3 . The dishwasher of  claim 2 , wherein the guide protrusion comprises:
 a first guide protrusion on the first outlet to guide the first outlet cap to the first seating position of the outlet cap; and   a second guide protrusion on the second outlet to guide the second outlet cap to the second seating position of the outlet cap.   
     
     
         4 . The dishwasher of  claim 2 , wherein the outlet cap comprises a guide hole formed to be coupled to the guide protrusion. 
     
     
         5 . The dishwasher of  claim 4 , wherein the guide hole is formed to be larger than the guide protrusion to allow the outlet cap to be rotatably coupled to the outlet. 
     
     
         6 . The dishwasher of  claim 1 , wherein the outlet cap coupling portion comprises a coupling protrusion formed to fix the outlet cap coupled to the outlet. 
     
     
         7 . The dishwasher of  claim 1 , wherein the outlet cap comprises a drain hole formed to drain water in the blower duct therethrough. 
     
     
         8 . The dishwasher of  claim 1 , wherein the outlet cap comprises an discharge guide rib formed at an angle to guide a discharge direction of the air discharging from the outlet. 
     
     
         9 . The dishwasher of  claim 8 , wherein the discharge guide rib is formed to discharge the air in a first direction in response to the first outlet cap being in the first seating position, and
 to discharge the air in a second direction which is different from the first direction, in response to the second outlet cap being in the second seating position.   
     
     
         10 . The dishwasher of  claim 1 , further comprising:
 an inlet cover configured to be coupled to the inlet to cover the blower fan.   
     
     
         11 . The dishwasher of  claim 10 , wherein the blower duct comprises an inlet cover coupling portion configured to allow the inlet cover to be coupled to the inlet. 
     
     
         12 . The dishwasher of  claim 11 , wherein the inlet cover comprises:
 a body portion configured to cover the blower fan so as to prevent water in the tub from flowing into the blower fan; and   a duct coupling portion configured to be coupled to the inlet cover coupling portion.   
     
     
         13 . The dishwasher of  claim 12 , wherein the body portion and the duct coupling portion are formed integrally. 
     
     
         14 . The dishwasher of  claim 12 , wherein the inlet cover further comprises a protruding portion protruding from the body portion toward an inside of the tub. 
     
     
         15 . The dishwasher of  claim 12 , wherein the inlet cover further comprises an inlet guide rib formed at an angle to guide the air to the blower fan. 
     
     
         16 . A dishwasher comprising:
 a tub;   a plurality of blower fans disposed at both sides of the tub to blow air;   an outlet formed in the tub to discharge the air blown by the plurality of blower fans, the outlet comprising:
 a first outlet; 
 a second outlet, the first outlet and the second outlet being at one side of the tub and spaced apart from each other in one direction; 
 a third outlet; and 
 a fourth outlet, the third outlet and the fourth outlet being at another side of the tub and spaced apart from each other in another direction different from the one direction; 
   an outlet cap configured to guide a direction of the air discharged through the outlet; and   an outlet cap coupling portion disposed around the outlet to allow the outlet cap to be coupled, the outlet cap coupling portion to guide a position where the outlet cap is coupled to the outlet.
