Drum type washing and drying machine

Abstract

Drum type washing and drying machine including a tub having a hot air inlet and a hot air outlet, a drying duct connected to the hot air inlet, the drying duct having a heater and a fan built in a flow passage therein for producing hot air, and a condensing duct connected to the hot air outlet and the drying duct, for removing moisture from the hot air, wherein the condensing duct includes a cooling water supply portion for guiding cooling water to the condensing duct, at least one water splashing projection in the condensing duct for splashing the cooling water, and a guide flow passage between the cooling water supply portion and the water splashing projection for guiding the cooling water to the water splashing projection.

1 . A drum type washing and drying machine comprising: 
 a tub having a hot air inlet and a hot air outlet;    a drying duct connected to the hot air inlet, the drying duct having a heater and a fan built in a flow passage therein for producing hot air; and    a condensing duct connected to the hot air outlet and the drying duct, for removing moisture from the hot air,    wherein the condensing duct includes;    a cooling water supply portion for guiding cooling water to the condensing duct,    at least one water splashing projection in the condensing duct for splashing the cooling water, and    a guide flow passage between the cooling water supply portion and the water splashing projection for guiding the cooling water to the water splashing projection.    
   
   
       2 . The drum type washing and drying machine as claimed in  claim 1 , wherein the cooling water supply portion is projected from a top side of the condensing duct.  
   
   
       3 . The drum type washing and drying machine as claimed in  claim 1 , wherein the guide flow passage is extended from a lower side of the cooling water supply portion along one side of the condensing duct.  
   
   
       4 . The drum type washing and drying machine as claimed in  claim 1 , wherein the guide flow passage has a semicircular section, substantially.  
   
   
       5 . The drum type washing and drying machine as claimed in  claim 1 , wherein the condensing duct, the cooling water supply portion, the guide flow passage, and the water splashing projections are molded as one body.  
   
   
       6 . The drum type washing and drying machine as claimed in  claim 1 , wherein the water splashing projection is projected from one portion of the guide flow passage.  
   
   
       7 . The drum type washing and drying machine as claimed in  claim 1 , wherein the water splashing projection is projected from an end of the guide flow passage.  
   
   
       8 . The drum type washing and drying machine as claimed in  claim 1 , wherein the water splashing projection is projected in a direction opposite to a direction of a depth of the guide flow passage.
