Drum type washing machine

Abstract

A drum type washing machine includes a rotating drum having a rotating axis in a substantially horizontal direction and sustained rotatably in a tub. The washing machine further includes a motor for driving the rotating drum, a water supply for supplying water into the tub, and a controller for washing, rinsing and liquid-extracting by controlling workings of the motor. The controller of the washing machine washes a laundry by pouring detergent bubbles in the washing process.

What is claimed is:  
     
         1 . A drum type washing machine comprising: 
 (a) a rotating drum having a rotating axis away from a vertical direction, and sustained rotatably in a tub;    (b) a motor for driving the rotating drum;    (c) a water supply unit for supplying water into the tub; and    (d) a controller for controlling the motor,    wherein laundry in the rotating drum is washed by pouring detergent bubbles thereon comprised of water from said water supply unit and detergent.    
     
     
         2 . A drum type washing machine comprising: 
 (a) a rotating drum having a substantially tilted rotating axis, and sustained rotatably in a tub;    (b) a motor for driving the rotating drum;    (c) a water supply unit for supplying water into the tub; and    (d) a controller for controlling the motor,    wherein laundry in the rotating drum is washed by pouring detergent bubbles thereon comprised of water from said water supply unit and detergent.    
     
     
         3 . The drum type washing machine of  claim 1 , wherein the rotating drum is rotated while the detergent bubbles are poured into the rotating drum.  
     
     
         4 . The drum type washing machine of  claim 2 , wherein the rotating drum is rotated while the detergent bubbles are poured into the rotating drum.  
     
     
         5 . The drum type washing machine of  claim 3 , wherein the controller controls the number of revolutions of the rotating drum while the detergent bubbles are poured into the rotating drum.  
     
     
         6 . The drum type washing machine of  claim 4 , wherein the controller controls the number of revolutions of the rotating drum while the detergent bubbles are poured into the rotating drum.  
     
     
         7 . The drum type washing machine of  claim 1 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         8 . The drum type washing machine of  claim 2 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         9 . The drum type washing machine of  claim 3 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         10 . The drum type washing machine of  claim 4 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         11 . The drum type washing machine of  claim 5 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         12 . The drum type washing machine of  claim 6 , wherein the rotating drum rotates in normal and reverse direction in a state where the laundry in the rotating drum is thoroughly covered with bubbles.  
     
     
         13 . The drum type washing machine of  claim 1 , wherein after the detergent bubbles are produced by continuously rotating detergent and water with the rotating drum, the detergent bubbles are poured onto the laundry by changing the number of revolutions of the rotating drum.  
     
     
         14 . The drum type washing machine of  claim 2 , wherein after the detergent bubbles are produced by continuously rotating detergent and water with the rotating drum, the detergent bubbles are poured onto the laundry by changing the number of revolutions of the rotating drum.  
     
     
         15 . The drum type washing machine of  claim 1 , wherein the rotating axis is substantially horizontal.  
     
     
         16 . The drum type washing machine of  claim 1 , wherein said detergent bubbles are poured on said laundry above a highest portion of said axis which is within said drum.  
     
     
         17 . The drum type washing machine of  claim 2 , wherein said detergent bubbles are poured on said laundry above a highest portion of said axis which is within said drum.
