Drum washing machine

Abstract

A drum washing machine for allowing a user to take laundry, attached to several positions of the inner cylindrical surface of a drum or entangled in the drum, out of the drum. The drum includes a main body to contain laundry, an opening which extends forward from the main body so that the laundry is placed into the main body through the opening, and a plurality of protrusions spaced from each other and disposed on an inner cylindrical surface of the opening so that the drum can be manually rotated. The drum is inclined so that a height of a front end of the drum at the opening is formed is higher than that of a rear end of the drum. Accordingly, when washing of the laundry is completed, the drum is rotated using the protrusions, thereby allowing the user to easily take the laundry out of the drum.

1 . A drum washing machine comprising: 
 a housing to define an exterior appearance of the drum washing machine; and    a drum rotatably installed in the housing, and comprising: 
 a main body forming an inner space storing laundry to be washed therein,  
 an opening extended from a front end of the main body to a front surface of the housing, and  
 a plurality of protrusions spaced from each other by a designated interval and disposed on the inner cylindrical surface of the opening so that the drum can be manually rotated.  
   
   
   
       2 . The drum washing machine as set forth in  claim 1 , wherein the protrusions comprise circular cross sections, and are arranged in plural lines in a transverse direction of the drum.  
   
   
       3 . The drum washing machine as set forth in  claim 1 , wherein the protrusions are extended in a transverse direction of the drum, and are arranged along a cylindrical surface of the opening.  
   
   
       4 . The drum washing machine as set forth in  claim 1 , wherein the protrusions are formed integrally with the opening by a press molding process.  
   
   
       5 . The drum washing machine as set forth in  claim 1 , wherein the protrusions are made separately from the opening, and are mounted to an inner cylindrical surface of the opening.  
   
   
       6 . The drum washing machine as set forth in  claim 1 , wherein the drum is inclined in the housing so that a height of a front end of the drum at which the opening is formed is higher than that of a rear end of the drum.  
   
   
       7 . A drum for drum washing machines comprising: 
 a main body to contain laundry therein;    an opening which extends forward from the main body so that the laundry is placed into the main body through the opening; and    a plurality of protrusions spaced from each other by a designated interval and disposed on an inner cylindrical surface of the opening so that the drum can be manually rotated.    
   
   
       8 . A washing machine comprising: 
 a drum inclined at a predetermined angle such that a front end thereof is positioned higher than a rear end thereof; and    protrusions spaced apart on an inner surface of an opening of the drum to allow the drum to be manually rotated.    
   
   
       9 . The washing machine of  claim 8 , wherein the protrusions comprise circular cross sections and are arranged in plural lines in a transverse direction of the drum.  
   
   
       10 . The washing machine of  claim 8 , wherein the protrusions are formed integrally with the opening by a press molding process.  
   
   
       11 . The washing machine of  claim 8 , wherein the protrusions are made separately from the opening and mounted to the opening.  
   
   
       12 . A washing machine comprising: 
 a drum inclined at a predetermined angle such that a front end thereof is positioned higher than a rear end thereof; and    means for manually rotating the drum to allow a user to retrieve laundry placed into the drum after a dehydrating operation of the washing machine.
