Washing machine

Abstract

Disclosed is a filter case coupling assembly and washing machine using the same, by which attachment/detachment of a filter case holding a noise filter is facilitated. The present invention includes a tub to hold water, a drum rotatably installed in the tub to hold laundry, a cabinet having the tub and drum inside, a control panel coupled to the cabinet to have a control unit inside, a filter case having a noise filter inside, and a filter case coupling assembly for sliding the filter case on the cabinet to be coupled thereto.

What is claimed is:  
     
         1 . A filter case coupling assembly comprising: 
 at least one coupling protrusion formed at a filter case having a noise filter inside; and    at least one guide rail formed at a plate to guide the coupling protrusion to slide to be inserted therein wherein the filter case is mounted on the plate.    
     
     
         2 . The filter case as claimed in  claim 1 , wherein the coupling protrusion protrudes in a lateral direction from a lower edge of each side of the filter case.  
     
     
         3 . The filter case as claimed in  claim 1 , the coupling protrusion comprising: 
 a body protruding downward from a bottom of the filter case; and    guide protrusions protruding in a lateral direction from lower edges of both sides of the body, respectively.    
     
     
         4 . The filter case as claimed in  claim 1 , wherein a front side of the guide rail is blocked so that the coupling protrusion inserted as long as a predetermined distance is unable to move ahead.  
     
     
         5 . A washing machine comprising: 
 a tub to hold water;    a drum rotatably installed in the tub to hold laundry;    a cabinet having the tub and drum inside;    a control panel coupled to the cabinet to have a control unit inside;    a filter case having a noise filter inside, the noise filter preventing the control signals carried on the wires  80  from interfering with other signals or from attenuating; and    a filter case coupling assembly sliding on the cabinet and coupling the filter case to the cabinet.    
     
     
         6 . The washing machine as claimed in  claim 5 , wherein the filter case is  31  coupled to a top plate forming a topside of the cabinet.  
     
     
         7 . The washing machine as claimed in  claim 6 , wherein the filter case is coupled to an upper surface of the top plate.  
     
     
         8 . The washing machine as claimed in  claim 7 , the filter case coupling assembly comprising: 
 a pair of coupling protrusions protruding in a lateral direction from lower edges of both sides of the filter case, respectively; and    a pair of guide rails formed at the top plate to guide the coupling protrusions to slide to be inserted therein for coupling.    
     
     
         9 . The washing machine as claimed in  claim 7 , the filter case coupling assembly comprising: 
 at least one coupling protrusion protruding from a bottom of the filter case; and    at least one guide rail formed at the top plate to guide the coupling protrusion to slide to be inserted therein for coupling.    
     
     
         10 . The washing machine as claimed in  claim 9 , the coupling protrusion comprising: 
 a body protruding downward from the bottom of the filter case; and    a pair of guide protrusions protruding in a lateral direction from lower edges of both sides of the body, respectively.    
     
     
         11 . The washing machine as claimed in  claim 8 , wherein a front side of the guide rail is blocked so that the coupling protrusion inserted as long as a predetermined distance is unable to move ahead.  
     
     
         12 . The washing machine as claimed in  claim 9 , wherein a front side of the guide rail is blocked so that the coupling protrusion inserted as long as a predetermined distance is unable to move ahead.  
     
     
         13 . The washing machine as claimed in  claim 7 , wherein the control panel is coupled to rear parts of the upper surface of the top plate.  
     
     
         14 . The washing machine as claimed in  claim 13 , wherein the filter case is provided under the control panel.
