Abstract

The laundry machine includes a cabinet ( 110 ), a tub ( 120 ) in the cabinet for holding washing water, a drum ( 130 ) rotatably mounted in the tub ( 120 ), a heater ( 115 ) in the tub for heating the washing water, and a control unit for controlling the heater and the drum, wherein the control unit controls heater to operate selectively in a spinning course for drying washing objects.

1 . A laundry machine comprising:
 a cabinet;   a tub provided in the cabinet for holding washing water;   a drum rotatably provided in the tub;   a heater provided in the tub for heating the washing water; and   a control unit controlling the heater and the drum,   wherein the control unit selectively operates the heater in a spinning course for drying washing objects.   
     
     
         2 . The laundry machine as claimed in  claim 1 , wherein the control unit turns on/off the heater in predetermined periods. 
     
     
         3 . The laundry machine as claimed in  claim 1 , wherein the control unit operates the heater below a predetermined temperature so that the heater is not overheated. 
     
     
         4 . The laundry machine as claimed in  claim 2 , wherein the control unit rotates the drum higher than a predetermined speed. 
     
     
         5 . The laundry machine as claimed in  claim 3 , wherein the control unit rotates the drum higher than a predetermined speed. 
     
     
         6 . he laundry machine as claimed in  claim 1 , further comprising an air-flow device for causing an air flow in the tub. 
     
     
         7 . The laundry machine as claimed in  claim 6 , wherein the air-flow device comprises a fan provided in an air flow passage communicating an inside of the tub with an outside of the tub. 
     
     
         8 . The laundry machine as claimed in  claim 7 , wherein the control unit operates the fan when the heater is operated. 
     
     
         9 . A method for controlling a laundry machine having a washing course, a rinsing course and a spinning course, comprising the steps of:
 operating a heater in the spinning course selectively; and   rotating a drum higher than a predetermined speed.   
     
     
         10 . The method as claimed in  claim 9 , wherein the control unit turns on/off the heater in predetermined periods. 
     
     
         11 . The method as claimed in  claim 9 , wherein the control unit operates the heater below a predetermined temperature so that the heater is not overheated.
