Washing machine

Abstract

Provided is a washing machine having an enhanced drying performance. The washing machine includes: a housing; a tub installed inside the housing, for storing washing water; a drum rotatably installed inside the tub and configured to wash laundry; a drying duct connected to the tub, for generating hot air and feeding the generated hot air to an inside of the drum; a condensation duct connected to the tub and the drying duct, for removing moisture from an air discharged from the tub to guide the moisture-removed air to the drying duct and allowing the hot air to cross the inside of the drum together with the drying duct; and a radiation mechanism disposed at the drying duct, for radiating heat of the drying duct.

1 . A washing machine comprising: 
 a housing;    a tub installed inside the housing, for storing washing water;    a drum rotatably installed inside the tub and configured to wash laundry;    a drying duct connected to the tub, for generating hot air and feeding the generated hot air to an inside of the drum;    a condensation duct connected to the tub and the drying duct, for removing moisture from an air discharged from the tub to guide the moisture-removed air to the drying duct and allowing the hot air to cross the inside of the drum together with the drying duct; and    a radiation mechanism disposed at the drying duct, for radiating heat of the drying duct.    
   
   
       2 . The washing machine of  claim 1 , wherein the drying duct and the condensation duct are configured to allow the hot air to fully and completely cross the inside of the drum in an axial direction thereof.  
   
   
       3 . The washing machine of  claim 1 , wherein the drying duct and the condensation duct are configured to flow the hot air from a front side of the drum to a rear side of the drum.  
   
   
       4 . The washing machine of  claim 1 , wherein the drying duct and the condensation duct are configured to flow the hot air in a diagonal direction inside the drum.  
   
   
       5 . The washing machine of  claim 1 , wherein the drying duct and the condensation duct are configured to flow the hot air from a front upper side of the drum to a rear lower side of the drum.  
   
   
       6 . The washing machine of  claim 1 , wherein the drying duct is connected to a front upper portion of the tub.  
   
   
       7 . The washing machine of  claim 1 , wherein the tub comprises an inlet formed at a front upper portion thereof and communicating with the drying duct.  
   
   
       8 . The washing machine of  claim 1 , wherein the drum comprises an inlet formed at a front upper portion thereof and communicating with the drying duct.  
   
   
       9 . The washing machine of  claim 1 , wherein the drying duct comprises a heater and a blower fan at an inside thereof.  
   
   
       10 . The washing machine of  claim 1 , wherein the drying duct closely contacts an outer circumference of the tub.  
   
   
       11 . The washing machine of  claim 1 , wherein the drying duct comprises an upper cover and a lower cover coupled to each other.  
   
   
       12 . The washing machine of  claim 1 , wherein the upper cover of the drying duct is made of steel.  
   
   
       13 . The washing machine of  claim 11 , wherein the lower cover of the drying duct is made of aluminum alloy.  
   
   
       14 . The washing machine of  claim 1 , wherein the condensation duct is connected to a rear portion of the tub.  
   
   
       15 . The washing machine of  claim 1 , wherein the condensation duct is connected to a rear lower portion of the tub.  
   
   
       16 . The washing machine of  claim 1 , wherein the radiation mechanism is provided at an upper portion of the drying duct.  
   
   
       17 . The washing machine of  claim 1 , wherein the radiation mechanism comprises at least one radiation fin provided in the drying duct.  
   
   
       18 . The washing machine of  claim 1  wherein the radiation mechanism comprises at least one radiation groove formed at the drying duct.  
   
   
       19 . The washing machine of  claim 1 , wherein the radiation mechanism comprises at least one radiation fin and at least one radiation groove provided in the drying duct.  
   
   
       20 . The washing machine of  claim 19 , wherein the radiation mechanism comprises a plurality of radiation fins and a plurality of radiation grooves, and the radiation fins and the radiation grooves are alternatively arranged.
