Definitions

  • the circulation device 40 operates the circulation pump 42 during the washing or rinsing cycle such that the pumped water can be sprayed to the rear surface of the drum 30 and the flange shaft 32 through the first washing pipe 61, and thus removes contaminants remaining on the rear surface of the drum 30 and the flange shaft 32 during the washing or rinsing cycle.
  • the circulation device 40 operates the circulation pump 42 and opens the circulation valve 44 when the washing or rinsing cycle is performed, thus circulating the water in the tub 20 through the circulation pipe 43.
  • the second washing pipe 64 may be connected directly to the water supply valve 52 without using the second washing valve 66 such that the water supplied to the second washing pipe 64 and the second nozzle 65 can be shut out by the operation of the water supply valve 52.
  • the water sprayed to the rear surface of the tub 20 during the dehydrating cycle is remaining water during the dehydrating cycle or additionally supplied water after the dehydrating cycle.
  • the circulation device 40 operates the circulation pump 42 and opens the circulation valve 44 during the washing or rinsing cycle, and thus circulates the water in the tub 20 through the circulation pipe 43.
  • the water supply device 50 supplies water to the inside of the tub 20 in the washing or rinsing cycle, and supplies water to the second washing pipe 64 connected to the water supply pipe 51 during the washing or rinsing cycle.
  • the control unit 70 controls the operation of the second washing valve 66 connected to the water supply pipe 51 when the drum 30 is rotated during the respective washing or rinsing cycle, and thus sprays water to the rear surface of the drum 30 through the second washing pipe 64.
  • the control unit 70 controls the operation of the second washing valve 66 connected to the water supply pipe 51 during the dehydrating cycle, and thus sprays the water supplied from the water supply pipe 51 to the rear surface of the drum 30 through the second washing pipe 64.
  • the circulation pump 42 is operated to pump the water in the tub 20, and the circulation valve 44 is opened to supply the pumped water again to the inside of the tub 20 through the channel pipe 41 and the circulation pipe 43. Then, the circulation pump 42 is stopped, and the circulation valve 44 is closed.
  • the drum 30 is rotated and the washing or rinsing cycle of laundry in the drum 30 is performed using the water circulated by the circulation pump 42 (operation 101).
  • the circulation pump 42 and the first washing valve 63 are operated to supply the water in the tub 20 pumped by the circulation pump 42 to the nozzle 62 installed on the rear surface of the tub 20 through the channel pipe 41 and the first washing pipe 61, thus washing the rear surface of the drum 30 while soaking residue of the detergent and foreign substances remaining on the rear surface of the drum 30 (operation 102).
  • the circulation pump 42 is operated under the condition that water remains in the tub 20, a designated level of water remains in the tub 20 during the draining cycle and then the draining cycle is stopped, or water is additionally supplied to the tub 20 after the draining cycle has been completed.
  • the water level sensor 80 senses the level of the water in the tub 20 from this point of time when the draining cycle is started, and the draining cycle is stopped when the sensed level reaches a predetermined level.
  • water is supplied from the water supply device 50 to the tub 20 (operation 104). Then, the level of the supplied water is sensed and is compared with the predetermined level (operation 105). When the sensed water reaches the predetermined level, the supply of water is stopped (operation 106). If the sensed water does not reach the predetermined level, water is continuously supplied until the water level is sensed to reach the designated level.
  • FIG. 7 is a flow chart illustrating a method of controlling the drum washing machine in accordance with the second embodiment. The method will be described with reference to FIGS. 2A , 2B , 3 , and 5 .
  • water is supplied to the inside of the tub 20 through the water supply pipe 51 of the water supply device 50, and the washing or rinsing cycle is started using the supplied water.
  • the circulation pump 42 is operated to pump the water in the tub 20, and the circulation valve 44 is opened to supply the pumped water again to the inside of the tub 20 through the channel pipe 41 and the circulation pipe 43. Then, the circulation pump 42 is stopped, and the circulation valve 44 is closed.
  • the washing operation to remove the foreign substances, etc. on the rear surface of the drum 30 may be periodically carried out after the operation of the circulation pump 42 to wash or rinse the laundry has been carried out at least one time.
  • the operation of the circulation pump 42 to wash or rinse the laundry is repeated three times, and then the washing operation to remove the foreign substances, etc. on the rear surface of the drum 30 is carried out one time.
  • the washing of the rear surface of the drum 30 may be performed for each of the washing cycle and plural rinsing cycles or for at least one cycle of the washing cycle, plural rinsing cycles, or dehydrating cycle, or be periodically performed according to the number of used times of the washing machine by a user.
  • the laundry in the drum 30 is washed or rinsed and the rear surface of the drum 30 is washed while the washing or rinsing of the laundry is performed, and thus residue of the detergent, mold, contaminants remaining on the rear surface of the drum 30 and the flange shaft 32 can be immediately removed.
  • the draining cycle is performed (operation 203).
  • the dehydrating cycle to dehydrate the laundry is performed and simultaneously, the second washing valve 66 connected to the water supply pipe 51 is operated to spray water to the rear surface of the drum 30 through the second washing pipe 64 and the second nozzle 65, thus washing the rear surface of the drum 30 and the flange shaft 32 (operation 204).
  • the washing machine does not need to be disassembled to wash the drum and tub and thus is easily washed, and the washing method performs the washing of the drum for each of washing, rinsing, and dehydrating cycles and thus maintains sanitary conditions without leaving residue of the detergent and foreign substances. Thereby, contamination of the insides of the drum and tub is minimized.
  • the ribs are formed on the flange shaft, which thus increases the strength of the flange shaft.
  • the ribs are extended in the same direction of the extension direction of the flange shaft, and thus form channels of water flowing on the flange shaft in the washing or rinsing cycle and reduce the remaining of contaminants on the flange shaft. Further, the contaminants remaining on the flange shaft are easily removed and thus the washability of the flange shaft is enhanced.
  • the washing machine minimizes the contaminants remaining on the flange shaft, and thus prevents the generation of a bad smell caused by bacteria and mold and maintains sanitary conditions.
