Abstract

The present invention provides a dryer washer, in which hot air for drying a laundry within a drum is discharged outside the drum after being fully used in drying the laundry and by which a gasket provided between a door and a drum is prevented from being torn. The present invention includes a case, a tub provided within the case, a drum rotatably provided within the tub, a condensing duct connected to the tub, the condensing duct sucking air of the tub therein to condense the sucked-in air, and a drying duct connected to a front portion of the tub and the condensing duct to supply dry and hot air to the tub.

Claims

exact text as granted — not AI-modified

       5 . The dryer washer of  claim 1 , wherein a plurality of air holes are provided to a front portion of the drum confronting the front portion of the tub to introduce the hot air in the tub into the drum.  
   
   
       6 . The dryer washer of  claim 5 , wherein a plurality of the air holes are provided to the front portion of the drum in a circumferential direction.  
   
   
       7 . The dryer washer of  claim 5 , wherein a plurality of embossed portions are provided to the front portion of the drum to be outwardly projected from the drum and wherein a plurality of the air holes are provided to centers of a plurality of the embossed portions, respectively.  
   
   
       8 . The dryer washer of  claim 7 , wherein tips of a plurality of the embossed portions are smoothly cut.  
   
   
       9 . The dryer washer of  claim 1 , further comprising an insulator provided between the tub and the drying duct to prevent heat of the drying duct from being transferred to the tub.  
   
   
       10 . A dryer washer comprising: 
 a case;    a tub provided within the case;    a drum rotatably provided within the tub;    a drying duct connected to the tub to supply dry and hot air to the tub; and    a condensing duct connected to a rear portion of the tub and the drying duct, the condensing duct sucking air of the tub therein to condense the sucked-in air, the condensing duct leading the condensed air to the drying duct.    
   
   
       11 . The dryer washer of  claim 10 , wherein the condensing duct sucks the air from the drum along an axial direction of the tub.  
   
   
       12 . The dryer washer of  claim 10 , wherein the condensing duct is connected to a lower rear portion of the drum.  
   
   
       13 . The dryer washer of  claim 10 , wherein the condensing duct comprises a water supply pipe connected to an upper portion of the condensing duct to supply cooling water for condensing the air to the condensing duct.  
   
   
       14 . The dryer washer of  claim 10 , further comprising an insulator provided between the tub and the drying duct to prevent heat of the drying duct from being transferred to the tub.  
   
   
       15 . A dryer washer comprising: 
 a case;    a tub provided within the case;    a drum rotatably provided within the tub;    a condensing duct connected either a front or rear portion of the tub, the condensing duct sucking air of the tub therein to condense the sucked-in air; and    a drying duct connected to either the rear or front portion of the tub and the condensing duct to supply dry and hot air to the tub.    
   
   
       16 . The dryer washer of  claim 15 , wherein the air within the drum continuously flows in a diagonal direction within the drum.  
   
   
       17 . The dryer washer of  claim 15 , wherein the drying duct supplies the hot air to the drum along an axial direction of the drum.  
   
   
       18 . The dryer washer of  claim 15 , wherein the drying duct is connected to an upper part of the front portion of the tub.  
   
   
       19 . The dryer washer of  claim 15 , wherein a plurality of air holes are provided to a front portion of the drum confronting the front portion of the tub to introduce the hot air in the tub into the drum.  
   
   
       20 . The dryer washer of  claim 19 , wherein a plurality of the air holes are provided to the front portion of the drum in a circumferential direction.  
   
   
       21 . The dryer washer of  claim 19 , wherein a plurality of embossed portions are provided to the front portion of the drum to be outwardly projected from the drum and wherein a plurality of the air holes are provided to centers of a plurality of the embossed portions, respectively.  
   
   
       22 . The dryer washer of  claim 21 , wherein tips of a plurality of the embossed portions are smoothly cut.  
   
   
       23 . The dryer washer of  claim 15 , wherein the condensing duct sucks the air from the drum along an axial direction of the drum.  
   
   
       24 . The dryer washer of  claim 15 , wherein the condensing duct is connected to a lower part of the rear portion of the drum.  
   
   
       25 . The dryer washer of  claim 15 , wherein the condensing duct comprises a water supply pipe connected to an upper portion of the condensing duct to supply cooling water for condensing the air to the condensing duct.
