Abstract

Provided is a dishwasher. The dishwasher includes an outer door; an inner door having a first through hole; and an air discharge device disposed between the outer door and the inner door, the air discharge device including an air duct and a fan, the air duct being in communication with a washing chamber of the dishwasher through the first through hole, the air duct having a water return opening upstream of the fan, and the water return opening being configured to allow external air to enter the air duct from the water return opening during an operation of the fan and to discharge condensate water into the washing chamber.

What is claimed is: 
     
         1 . A dishwasher, comprising:
 an outer door;   an inner door connected to the outer door and having a first through hole; and   an air discharge device disposed between the outer door and the inner door, the air discharge device comprising an air duct and a fan, the air duct being in communication with a washing chamber of the dishwasher through the first through hole, the fan being adapted to draw air from the washing chamber into the air duct and discharge the air out of the air duct, the air duct having a water return opening upstream of the fan, and the water return opening being configured to allow external air to enter the air duct from the water return opening during an operation of the fan and to discharge condensate water into the washing chamber.   
     
     
         2 . The dishwasher according to  claim 1 , further comprising a tub, the tub comprising a bottom plate enclosing the washing chamber, and the water return opening being located above the bottom plate and spaced apart from the bottom plate. 
     
     
         3 . The dishwasher according to  claim 2 , wherein the water return opening is located directly above the bottom plate. 
     
     
         4 . The dishwasher according to  claim 3 , wherein the condensate water drips from the water return opening onto the bottom plate. 
     
     
         5 . The dishwasher according to  claim 1 , wherein the water return opening is open downwardly. 
     
     
         6 . The dishwasher according to  claim 1 , wherein the water return opening is in communication with a space between the inner door and the outer door. 
     
     
         7 . The dishwasher according to  claim 1 , wherein:
 the water return opening is located below an inlet of the fan; and/or   an open direction of the water return opening spatially intersects with an air intake direction of the fan.   
     
     
         8 . The dishwasher according to  claim 1 , wherein the water return opening is arranged adjacent to the fan. 
     
     
         9 . The dishwasher according to  claim 1 , wherein the air duct includes a condensation segment extending in an up-down direction, the water return opening being located below the condensation segment. 
     
     
         10 . The dishwasher according to  claim 9 , wherein an open direction of the water return opening is the same as an extension direction of the condensation segment. 
     
     
         11 . The dishwasher according to  claim 1 , wherein the air duct comprises an air intake segment, a condensation segment, and an air discharge segment that are sequentially in communication with each other, the air intake segment being constructed as an inverted U-shape and in communication with the washing chamber, the fan being disposed in the air discharge segment, and the water return opening being disposed in one of the air discharge segment and the condensation segment. 
     
     
         12 . The dishwasher according to  claim 11 , wherein the air duct comprises an air intake tube forming the air intake segment, a condensate tube forming the condensate segment, and an air discharge tube forming the air discharge segment, and the fan and the water return opening being located in the air discharge segment. 
     
     
         13 . The dishwasher according to  claim 11 , wherein:
 the fan is located below ½ or ⅓ of a height of the inner door; and   the air discharge segment has an air discharge opening located below the inner door and the outer door.
