Washing machine

Abstract

The present invention provides a washing machine capable of suppressing vibration and noise and capable of reducing a gap between a circumferential wall of an outer tub and a housing so as to reduce a useless space. The washing machine includes a box-shaped housing having an internal space opened upward; and a washing tub unit suspended and supported through a hanger bar in the internal space. The washing tub unit includes an outer tub presented in a bottomed quasi-cylindrical shape; an inner tub presented in a bottomed quasi-cylindrical shape, coaxially configured inside the outer tub and rotatably supported by the outer tub; and a driving mechanism arranged at a lower end of the outer tub and configured to drive the inner tub to rotate.

1 . A washing machine, comprising:
 a box-shaped housing having an internal space opened upward; and   a washing tub unit suspended and supported in the internal space through a hanger bar,   wherein the washing tub unit comprises an outer tub presented in a bottomed quasi-cylindrical shape; an inner tub presented in a bottomed quasi-cylindrical shape, coaxially configured inside the outer tub and rotatably supported by the outer tub; and a driving mechanism arranged at a lower end of the outer tub and configured to drive the inner tub to rotate;   a base end side of the hanger bar is mounted in the vicinity of an upper end of the housing, and a top end side is installed at a lower portion of the outer tub; and   a center of gravity of the washing tub unit is set at a position higher than a height center in a vertical direction of the housing.   
     
     
         2 . The washing machine according to  claim 1 , wherein
 the hanger bar is mounted at a predetermined angle, and the top end side is mounted at a suspended supporting portion arranged at the lower portion of a circumferential wall of the outer tub; and   the suspended supporting portion is set at a position higher than the height center in the vertical direction of the housing.   
     
     
         3 . The washing machine according to  claim 2 , wherein
 the driving mechanism selectively drives the inner tub and an agitator arranged at a bottom of the inner tub by transferring a rotating force of a motor; and   a depth of the inner tub is set in a range of 50% to 70% of a diameter of the inner tub.   
     
     
         4 . The washing machine according to  claim 2 , wherein an accommodating portion is arranged below the washing tub unit. 
     
     
         5 . The washing machine according to  claim 4 , wherein the accommodating portion is a drawer. 
     
     
         6 . The washing machine according to  claim 3 , wherein an accommodating portion is arranged below the washing tub unit. 
     
     
         7 . The washing machine according to  claim 6 , wherein the accommodating portion is a drawer.
