         4 . The cup washer of  claim 3 , wherein the drying part further comprises a tub connection pipe extending from a second end of the drying duct, the tub connection pipe having a tub connector connected to the rear surface of the tub. 
     
     
         5 . The cup washer of  claim 4 , wherein the blowing fan is located relatively higher than the tub connector. 
     
     
         6 . The cup washer of  claim 4 , wherein the drying part further comprises an air heater disposed in the drying duct, the air heater being configured to heat air passing through the internal flow path, and
 wherein the internal flow path includes:
 a first section extending upward from the blowing fan; 
 a second section extending laterally from the first section, the air heater being located in the second section; and 
 a third section extending downward from the second section to the tub connection pipe. 
   
     
     
         7 . The cup washer of  claim 4 , wherein the tub connection pipe extends downward between the second end of the drying duct and the tub connector. 
     
     
         8 . The cup washer of  claim 4 , wherein the drying duct further comprises:
 a first assembly located between the tub and the rear panel; and   a second assembly coupled to the first assembly, the second assembly being located between the first assembly and the rear panel, the first assembly and the second assembly defining the internal flow path and the second end of the drying duct, and   
       wherein the tub connection pipe is inserted and coupled to the second end of the drying duct. 
     
     
         9 . The cup washer of  claim 8 , wherein the tub connection pipe has an integrated tubular shape. 
     
     
         10 . The cup washer of  claim 8 , further comprising:
 a front frame located at a front side of the tub, the front frame being configured to support the front panel; and   a rear frame located at the rear side of the drying part, the rear frame being configured to support the rear panel.   
     
     
         11 . The cup washer of  claim 10 , wherein the drying part is coupled to and supported by the rear frame. 
     
     
         12 . The cup washer of  claim 11 , wherein the second assembly is fastened to the rear frame. 
     
     
         13 . The cup washer of  claim 4 , wherein the tub connection pipe is fitted and coupled to the second end of the drying duct. 
     
     
         14 . The cup washer of  claim 13 , wherein the second end of the drying duct is located relatively higher than a maximum water level in the tub. 
     
     
         15 . The cup washer of  claim 13 , wherein the second end of the drying duct is located relatively lower than the outside air inlet. 
     
     
         16 . The cup washer of  claim 4 , further comprising an air discharge part located at an upper end of the tub to discharge air inside the tub. 
     
     
         17 . The cup washer of  claim 16 , wherein the air discharge part is connected between the rear surface of the tub and the rear panel. 
     
     
         18 . The cup washer of  claim 17 , wherein a first portion of the air discharge part that is connected to the tub is located relatively lower than a second portion of the air discharge part that is connected to the rear panel.
