Washing machine having a condensing duct

Abstract

A washing machine includes a drum and a condensing duct that communicates with the drum. The condensing duct includes an air inlet unit, a condensing unit and an air outlet unit which are connected sequentially. A condensed water jetting member is provided inside the condensing unit and a backward flow blocking guide is provided inside the condensing unit. The condensing unit has a flow width larger than the air inlet unit and the air outlet unit.

       3 . The washing machine as claimed in  claim 1 , wherein the condensing unit has an upper flow width larger than a lower flow width thereof, and the backward flow blocking guide is projected on an upper internal wall face of the condensing unit.  
   
   
       4 . The washing machine as claimed in  claim 3 , further comprising a backward flow blocking projection to block the condensed water formed on an edge portion of the backward flow blocking guide from being backward flown by internally circulated air.  
   
   
       5 . The washing machine as claimed in  claim 4 , wherein a space portion is formed between the backward flow blocking guide and the backward flow blocking projection.  
   
   
       6 . The washing machine as claimed in  claim 4 , wherein the backward flow blocking guide and the backward flow blocking projection are integrally connected, and a space portion is formed between the backward flow blocking projection and an internal wall face of the condensing duct.  
   
   
       7 . The washing machine as claimed in  claim 2 , further comprising a condensed water scattering plate supported by a lower internal wall face of the condensing unit to be positioned on an upper part of the condensed water scattering unit, having an air passing hole communicating with the air inlet unit in a center region thereof.  
   
   
       8 . The washing machine as claimed in  claim 7 , wherein the air passing hole is sized larger than the air inlet unit.  
   
   
       9 . The washing machine as claimed in  claim 7 , wherein the condensed water scattering plate is arranged perpendicularly to a flowing direction of internally circulated air passing through the condensing duct.  
   
   
       10 . The washing machine as claimed in  claim 1 , wherein the air outlet unit has a bent flow path.  
   
   
       11 . The washing machine as claimed in  claim 2 , wherein a backward flow blocking projection is formed on a boundary region of the condensed water collecting unit and the air outlet unit.  
   
   
       12 . A dryer comprising: 
 a drum;    a condensing duct that communicates with the drum, comprising an air inlet unit, a condensing unit and an air outlet unit which are connected sequentially;    a condensed water jetting member provided inside the condensing unit;    a backward flow blocking guide provided inside the condensing unit; and    the condensing unit has a flow width larger than the air inlet unit and the air outlet unit.    
   
   
       13 . The dryer as claimed in  claim 12 , wherein the condensing duct is formed with at least one condensed water collecting unit which is protruded to collect condensed water backwardly flown by internally circulated air.  
   
   
       14 . The washing machine as claimed in  claim 2 , wherein the condensing duct is formed with an auxiliary condensed water collecting unit which is protruded to collect condensed water backwardly flowing after passing through the condensed water collecting unit.  
   
   
       15 . A washing machine comprising: 
 a drum;    a condensing duct that communicates with the drum;    a condensed water jetting member provided inside of the condensing duct; and    a backward flow blocking guide provided inside of the condensing duct,    wherein the condensing duct comprises at least one condensed water collecting unit which is protruded to collect condensed water backwardly flown by internally circulated air.    
   
   
       16 . The washing machine as claimed in  claim 15 , wherein the condensed water collecting unit is provided on an upper portion of the backward flow blocking guide.  
   
   
       17 . The washing machine as claimed in  claim 15 , wherein the condensing duct comprises an air inlet unit through which internal air of the drum is flown, a condensing unit through which air flown through the air inlet unit passes, and an air outlet unit through which the air having passed through the condensing unit passes, further comprising an auxiliary condensed water collecting unit which is protruded to collect condensed water backwardly flowing after passing through the condensed water collecting unit.
