Washing machine

Abstract

A washing machine is provided that includes a drum; and a condensing duct that communicates with the drum and is supplied with air from an inside of the drum. A coolant spray is provided inside the condensing duct, and sprays coolant from a lower portion to an upper portion of the condensing duct. A washing machine is thus provided that enhances condensation efficiency by increasing a contact time between hot moisture-laden air in a condensing duct and the coolant while decreasing time consumed during a drying phase. In addition, the washing machine can enhance the condensation efficiency by changing a spray direction of a coolant spray device.

1 . A washing machine comprising: 
 a drum;    a condensing duct which communicates with the drum, and is supplied with air from an inside of the drum; and    a coolant spray provided inside the condensing duct, and which sprays coolant in an upward direction.    
   
   
       2 . The washing machine according to  claim 1 , wherein the coolant spray sprays the coolant so that the coolant goes beyond the upper portion of the condensing duct and then falls down due to gravity.  
   
   
       3 . The washing machine according to  claim 1 , wherein the coolant spray comprises a spray nozzle.  
   
   
       4 . The washing machine according to  claim 2 , wherein the coolant spray comprises a spray nozzle.  
   
   
       5 . The washing machine according to  claim 1 , further comprising a v-shaped condensing guide protruded from an inner wall of the condensing duct.  
   
   
       6 . The washing machine according to  claim 2 , further comprising a v-shaped condensing guide protruded from an inner wall of the condensing duct.  
   
   
       7 . The washing machine according to  claim 5 , wherein the v-shaped condensing guide is positioned in the condensing duct above an area reached by the coolant spray.  
   
   
       8 . The washing machine according to  claim 6 , wherein the v-shaped condensing guide is positioned in the condensing duct above an area reached by the coolant spray.  
   
   
       9 . The washing machine according to  claim 1 , wherein the lower portion is in a lower half of the condensing duct.  
   
   
       10 . A washing machine comprising: 
 a drum;    a condensing duct which communicates with the drum, and is supplied with air from an inside of the drum; and    means for spraying coolant inside the condensing duct in an upward direction.    
   
   
       11 . The washing machine according to  claim 10 , wherein the means for spraying coolant sprays the coolant so that the coolant goes beyond the upper portion of the condensing duct and then falls down due to gravity.  
   
   
       12 . The washing machine according to  claim 10 , wherein the means for spraying coolant comprises a spray nozzle.  
   
   
       13 . The washing machine according to  claim 10 , further comprising a “v” shaped condensing guide protruded from an inner wall of the condensing duct.  
   
   
       14 . The washing machine according to  claim 13 , wherein the “v” shaped condensing guide is positioned in the condensing duct above an area reached by the coolant spray.  
   
   
       15 . A drying machine comprising: 
 a drum;    a condensing duct which communicates with the drum, and is supplied with air from an inside of the drum; and    a coolant spray provided inside the condensing duct, and which sprays coolant in an upward direction.
