Drum device for home appliance

Abstract

Drum device for a home appliance having a chamber for drying or washing laundry, including a sound attenuation member fitted to an outside surface thereof, thereby effectively attenuating noise caused by impact of articles, such as buttons, zippers, clips, and the like fitted to the laundry, to the metallic drum when the laundry introduced into the chamber is lifted and dropped as the drum rotates.

What is claimed is:  
     
         1 . A drum device for a home appliance comprising: 
 a drum having a chamber therein rotatably fitted for carrying out a work; and    vibration reductive sound insulating member fitted to the drum for insulating vibratory sound caused by collision of objects flowing inside of the chamber with the drum as the drum is rotated.    
     
     
         2 . A drum device as claimed in  claim 1 , wherein the vibration reductive sound insulating member is fitted around an outside circumferential surface of the drum.  
     
     
         3 . A drum device as claimed in  claim 2 , wherein the outside circumferential surface of the drum has recesses for fitting the vibration reductive sound insulating members therein.  
     
     
         4 . A drum device as claimed in  claim 1 , wherein a plurality of the vibration reductive sound insulating members are fitted to the outside surface of the drum in a length direction of the drum.  
     
     
         5 . A drum device as claimed in  claim 4 , wherein the outside circumferential surface of the drum has a plurality of recesses for fitting the vibration reductive sound insulating members therein in a length direction of the drum.  
     
     
         6 . A drum device as claimed in one of  claims 1  to  4 , wherein the vibration reductive sound insulating member is formed of an elastic material.  
     
     
         7 . A drum device as claimed in  claim 2  or  4 , wherein the vibration reductive sound insulating member is attached to the outside surface of the drum.  
     
     
         8 . A drum device as claimed in  claim 6 , wherein the vibration reductive sound insulating member has a form of sheet.  
     
     
         9 . A drum device as claimed in  claim 4 , wherein the vibration reductive sound insulating member is formed of butyl rubber.  
     
     
         10 . A drum device as claimed in  claim 1 , wherein the vibration reductive sound insulating member is a composite layer of a butyl rubber layer and a polyester layer.
