Drum type washing machine having vibration attenuating means

Abstract

Disclosed is a drum type washing machine having a vibration attenuating means, by which vibrations generated from driving the drum type washing machine are attenuated. The present invention includes a cabinet forming an exterior, a tub provided in the cabinet to have a front opening and to hold water, and detergent therein, a motor in rear of the tub 200 to have a horizontally installed rotational shaft, a drum in the tub to be rotated by the motor, and a vibration attenuating means that includes a damper unit under the tub to attenuate vertical and horizontal vibrations of the tub and an elastic member over the tub to attenuate a front-to-rear vibration of the tub.

What is claimed is:  
     
         1 . A drum type washing machine comprising: 
 a cabinet forming an exterior;    a tub provided in the cabinet to have a front opening and to hold water, and detergent therein;    a motor in rear of the tub  200  to have a horizontally installed rotational shaft;    a drum in the tub to be rotated by the motor; and    a vibration attenuating means comprising: 
 a damper unit under the tub to attenuate vertical and horizontal vibrations of the tub; and  
 an elastic member over the tub to attenuate a front-to-rear vibration of the tub.  
   
     
     
         2 . The drum type washing machine as claimed in  claim 1 , wherein the damper unit is installed at right and left sides under the tub.  
     
     
         3 . The drum type washing machine as claimed in  claim 2 , wherein the damper unit is installed at a middle portion between front and rear sides under the tub.  
     
     
         4 . The drum type washing machine as claimed in  claim 1 , wherein the elastic member is installed at front and rear sides over the tub.  
     
     
         5 . The drum type washing machine as claimed in  claim 4 , wherein the elastic member is installed at a middle portion between right and left sides over the tub.  
     
     
         6 . The drum type washing machine as claimed in  claim 5 , the cabinet comprising: 
 a base plate installed as a bottom of the cabinet;    a pair of side plates on both sides of the base plate;    a rear plate in rear of the base plate and the side plates;    a front plate in front of the base plate and the side plates; and    a top plate on the side, rear, and front plates.    
     
     
         7 . The drum type washing machine as claimed in  claim 6 , the elastic member comprising: 
 a front spring having one end connected to an upper front side of the tub to extend in an upper front direction and the other end connected to a lower front side of the top plate; and    a rear spring having one end connected to an upper rear of the tub to extend in an upper rear direction and the other end connected to a lower rear side of the top plate.    
     
     
         8 . The drum type washing machine as claimed in  claim 6 , the elastic member comprising: 
 a front spring having one end connected to an upper front side of the tub to extend in an upper front direction and the other end connected to a lower front side of the top plate; and    a rear spring having one end connected to an upper rear of the tub to extend in an upper rear direction and the other end connected to an upper side of the rear plate.    
     
     
         9 . The drum type washing machine as claimed in  claim 6 , the elastic member comprising: 
 a front spring having one end connected to an upper front side of the tub to extend in an upper front direction and the other end connected to an upper side of the front plate; and    a rear spring having one end connected to an upper rear of the tub to extend in an upper rear direction and the other end connected to a lower rear side of the top plate.    
     
     
         10 . The drum type washing machine as claimed in  claim 6 , the elastic member comprising: 
 a front spring having one end connected to an upper front side of the tub to extend in an upper front direction and the other end connected to an upper side of the front plate; and    a rear spring having one end connected to an upper rear of the tub to extend in an upper rear direction and the other end connected to an upper side of the rear plate.    
     
     
         11 . The drum type washing machine as claimed in  claim 6 , the tub comprising a connecting member at the upper front and rear sides to have the elastic member connected thereto.
