Washing machine

Abstract

A drum type washing machine is disclosed. The drum type washing machine includes a tub mounted in a case, a drum rotatably mounted in the tub, and a tilt reduction unit for reducing the downward tilt degree of the tub and the drum when laundry to be cleaned is received into the drum. According to the present invention, it is possible to reduce the downward tilt degree of the tub and the drum, and therefore, it is possible to increase the capacities of the tub and the drum without the modification of the case.

       3 . The drum type washing machine according to  claim 2 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum tilt upward by an angle of 0.5 to 1 degree when the laundry is not received into the drum. 
   
   
       4 . The drum type washing machine according to  claim 2 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum do not tilt upward by an angle of more than 1 degree when the laundry is not received into the drum. 
   
   
       5 . The drum type washing machine according to  claim 1 , wherein the tilt reduction unit includes a plurality of elastic members provided at the tub, such that the entrance sides of the tub and the drum do not tilt downward by more than a predetermined angle when a maximum amount of the laundry is received into the drum. 
   
   
       6 . The drum type washing machine according to  claim 5 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum tilt downward by an angle of 0.5 to 1 degree when a maximum amount of the laundry is received into the drum. 
   
   
       7 . The drum type washing machine according to  claim 5 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum do not tilt downward by an angle of more than 1 degree when a maximum amount of the laundry is received into the drum. 
   
   
       8 . A drum type washing machine comprising:
 a case;   a tub provided in the case;   a drum rotatably provided in the tub; and   a plurality of elastic members arranged at predetermined intervals from the center of gravity of the tub, to support the tub.   
   
   
       9 . The drum type washing machine according to  claim 8 , wherein the elastic members are mounted at opposite sides of the upper part of the tub. 
   
   
       10 . The drum type washing machine according to  claim 9 , wherein the elastic members are mounted at the tub such that one elastic member is mounted at each side of the upper part of the tub. 
   
   
       11 . The drum type washing machine according to  claim 8 , wherein the elastic members are mounted at the tub such that the elastic members are arranged at predetermined intervals toward the entrance side of the tub from the center of gravity of the tub. 
   
   
       12 . The drum type washing machine according to  claim 11 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum tilt upward by an angle of 0.5 to 1 degree when the laundry is not received into the drum. 
   
   
       13 . The drum type washing machine according to  claim 11 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum do not tilt upward by an angle of more than 1 degree when the laundry is not received into the drum. 
   
   
       14 . The drum type washing machine according to  claim 11 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum tilt downward by an angle of 0.5 to 1 degree when a maximum amount of the laundry is received into the drum. 
   
   
       15 . The drum type washing machine according to  claim 11 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum do not tilt downward by an angle of more than 1 degree when a maximum amount of the laundry is received into the drum. 
   
   
       16 . The drum type washing machine according to  claim 11 , wherein the elastic members are mounted at the tub such that the entrance sides of the tub and the drum tilt upward by an angle of 0.5 to 1 degree when the laundry is not received into the drum and such that the entrance sides of the tub and the drum do not tilt downward by an angle of more than 1 degree when a maximum amount of the laundry is received into the drum. 
   
   
       17 . A drum type washing machine comprising:
 a case;   a tub mounted in the case for receiving wash water;   a drum rotatably mounted in the tub for receiving laundry to be cleaned; and   a plurality of elastic members mounted at the outside of the tub, such that the elastic members are arranged at predetermined intervals toward the entrance side of the tub from the center of gravity of the tub, for allowing the entrance sides of the tub and the drum to tilt upward by a predetermined angle when the laundry is not received into the drum and preventing the entrance sides of the tub and the drum from tilting downward by more than a predetermined angle when a maximum amount of the laundry is received into the drum.
