Control method of laundry machine

Abstract

Control methods of a laundry machine are disclosed. One of them is a control method of a laundry machine comprising a water supplying step configured to drive the drum of the machine in scrub motion when water is supplied to the tub of the machine. Another control method of the laundry machine comprising a washing cycle with at least one water supplying step configured to drive the drum in a predetermined time period after water supply to the tub starts or after the water level reaches a predetermined value.

1 . A control method of a laundry machine comprising:
 a water supplying step configured to drive a drum in a scrub motion when water is supplied to a tub.   
     
     
         2 . The control method as claimed in  claim 1 , wherein a circulating step configured to circulate the water inside the tub to re-supply the water to the tub is implemented at the same time when the water supplying step starts. 
     
     
         3 . The control method as claimed in  claim 1 , wherein the laundry machine comprises a driving unit comprising a shaft connected to a drum, a bearing housing to rotatably support the shaft, and a motor to rotate the shaft, and a suspension assembly is connected to the driving unit. 
     
     
         4 . The control method as claimed in  claim 1 , wherein the laundry machine comprises a rear gasket for sealing to prevent washing water from leaking from a space between a driving unit and a tub, and enabling the driving unit movable relative to the tub. 
     
     
         5 . The control method as claimed in  claim 1 , wherein a tub is supported rigidly more than a drum being supported by a suspension assembly. 
     
     
         6 . A control method of a laundry machine comprising:
 a washing cycle comprising at least one water supplying step configured to drive a drum in a predetermined time period after water supply to a tub starts or after a water level reaches a predetermined value.   
     
     
         7 . The control method as claimed in  claim 6 , wherein the tub and the drum provided in the laundry machine have rear portions which are tilted downward, respectively. 
     
     
         8 . The control method as claimed in  claim 6 , wherein the tub and the drum provided in the laundry machine have rear portions which are tilted downward, respectively. 
     
     
         9 . The control method as claimed in  claim 8 , wherein a circulating line configured to circulate the water is connected to a front portion of the tub. 
     
     
         10 . The control method as claimed in  claim 6 , wherein a water supply line provided in the laundry machine is connected to a front portion of the tub, and
 the on-time of a water supply vale is set to be shorter than the off-time, when the water supply vale is turned on.   
     
     
         11 . The control method as claimed in  claim 10 , wherein the on-time is determined to allow water supplied via the water supply line to have less than a predetermined water pressure. 
     
     
         12 . The control method as claimed in  claim 11 , wherein the on-time of the water supply valve is determined to allow water supplied via the water supply line to have a predetermined water pressure high enough not to be directly supplied to the drum. 
     
     
         13 . The control method as claimed in  claim 1 , wherein the laundry machine comprises a driving unit comprising a shaft connected to a drum, a bearing housing to rotatably support the shaft, and a motor to rotate the shaft, and a suspension assembly is connected to the driving unit. 
     
     
         14 . The control method as claimed in  claim 6 , wherein the laundry machine comprises a rear gasket for sealing to prevent washing water from leaking from a space between a driving unit and a tub, and enabling the driving unit movable relative to the tub. 
     
     
         15 . The control method as claimed in  claim 6 , wherein a tub is supported rigidly more than a drum being supported by a suspension assembly.
