  • the hot water supply unit includes a hot water supply pipe 41 connected between the lower portion of the heating tank 31 and the access opening 12a of the rotating drum 12 to guide hot water from the heating tank 31 to the water tub 11 via the rotating drum 12, and a hot water supply valve 42 arranged in the hot water supply pipe 41 to control the supply of hot water through the hot water supply pipe 41.
  • the hot water supply pipe 41 is connected, at an inlet thereof, to a side wall of the heating tank 31 at the lower portion of the heating tank 31.
  • a hot water injection nozzle 43 is mounted to an outlet of the hot water supply pipe 41 in order to inject hot water from the hot water supply pipe 41 onto laundry contained in the rotating drum 12.
  • the steam supply unit includes a steam supply pipe 51 connected between an upper portion of the heating tank 31 and the water tub 11 to guide steam from the heating tank 31 to the water tub 11, and a steam supply valve 52 arranged in the steam supply pipe 51 to control the supply of steam through the steam supply pipe 51.
  • the steam supply pipe 51 extends horizontally into the interior of the heating tank 31 at the side wall of the heating tank 31, and is then bent to extend upwardly in the heating tank 31 so that its inlet is positioned at an upper portion of the heating tank 31 inside the heating tank 31.

  • the water remaining in the heating tank 31 can be drained after completion of hot water and steam generating operations. Accordingly, it is possible to prevent scales from being formed on the surface of the heater 32 due to foreign matter contained in the water contacting the heater 32, and thus, to prevent a degradation in the performance of the heater 32. That is, the time, for which the heater 32 is maintained in a state of being dipped in water, is reduced to minimize formation of scales on the surface of the heater 32, so that it is possible to prevent a degradation in the performance of the heater 32.
  • FIG. 3 illustrates a steam generating unit according to another embodiment of the present invention.
  • a heater 80 which is adapted to heat water contained in the heating tank 31, is installed outside the heating tank 31 such that it is in contact with a lower surface of the bottom of the heating tank 31. Since the heater 80 is installed outside the heating tank 31 in this configuration, it does not come into contact with the water contained in the heating tank 31. Accordingly, it is possible to prevent scales from being formed on the heater 80.
  • a drainage device for the steam generating unit may also be provided. As shown in FIG. 3, the drainage device, which is designated by reference numeral 70, includes a drainage pipe 71 connected to the side wall of the heating tank 31 at a lower portion of the heating tank 31, and a drainage valve 72 for opening and closing the drainage pipe 71.
  • the first and second water supply valves 22 and 25 are opened under the control of a control unit (not shown), thereby causing water to be supplied to both the detergent supply unit 18 and the steam generating unit 30.
  • the detergent contained in the detergent supply unit 18 is supplied into the water tub 11 in a state of being dissolved in the water supplied into the water tub 11 via the detergent supply unit 18.
  • the first water supply valve 22 is closed, thereby cutting off the supply of water to the first water supply pipe 21.
  • the steam supply valve 52, hot water supply valve 42 and drainage valve 62 or 72 at the side of the steam generating unit 30 are initially maintained in a closed state. Accordingly, the water supplied toward the steam generating unit 30 is introduced into the heating tank 31.
  • the control unit controls, based on a sensing operation of the water level sensor 33, the second supply valve 25 to be opened or closed such that the water in the heating tank 31 is maintained at a desired level. In this state, the control unit drives the heater 32 or 80 to heat the water in the heating tank 31.
  • the control unit controls the hot water supply valve 42 to be opened, so that hot water from the heating tank 31 is supplied into the water tub 11 via the rotating drum 12.
  • the control unit senses, based on a sensing operation of the temperature sensor 34, that the temperature of the water in the heating tank 31 has reached the predetermined temperature, that is, 30°C, it opens the hot water supply valve 42, thereby causing the hot water to be supplied to the water tub 11 via the rotating drum 12.
  • control unit senses, based on the sensing operation of the water level sensor 33, an excessive lowering of the water level in the heating tank 31 caused by the supply of hot water, it controls the second water supply valve 25 to be opened. Thus, the water level in the heating tank 31 is maintained at a desired level. As the above control operations are repeatedly carried out, hot water is continuously supplied into the water tub 11 via the rotating drum 12.
  • the hot water supply valve 42 is closed, thereby cutting off the supply of hot water.
  • the water in the heating tank 31 is continuously heated by the heater 32 or 80, so that steam is generated.
  • the control unit senses this state through the pressure sensor 35, and opens the steam supply valve 52 to supply steam into the water tub 11. Accordingly, the wash water contained in the water tub 11 is heated by the steam.
  • the control unit controls the supply of steam into the water tub 11 by controlling the steam supply valve 52 in such a manner that the steam supply valve 52 is closed when the internal pressure of the heating tank 31 is excessively lowered, while being opened when the internal pressure of the heating tank 31 is excessively increased.
  • the control unit also opens the second water supply valve 25 so as to supply water into the heating tank 31. This steam supplying operation is continued until the temperature of the wash water in the water tub 11 reaches a predetermined temperature for effective washing.
  • the steam supplying operation is continued until the water in the water tub 11, which is maintained at about 30°C by virtue of the hot water supplied into the water tub 11 via the rotating drum 12, is increased in temperature to 60°C as it is heated by the supplied stem.
  • the water level and water temperature in the water tub 11 are sensed by an additional water level sensor and an additional water temperature sensor, which are not shown.
  • the rotating drum 12 performs a washing operation while being rotated at low speed in accordance with operation of the motor 15.
  • a rinsing process involving repetition of spin-drying and water supplying operations is carried out.
  • the supply of water into the water tub 11 in the rinsing process is carried out through the first water supply pipe 21 in an opened state of the first water supply valve 22.
  • drainage of water from the water tub 11 is carried out in accordance with operation of the drainage pump 19c in an opened state of the drainage valve 19b.
  • a spin-drying process is carried out.
  • the drainage pump 19c is operated in the opened state of the drainage valve 19b. In this state, the rotating drum 12 is rotated at high speed for a predetermined time, thereby spin-drying the laundry.
  • control unit opens the drainage valve 62 connected to the lower portion of the heating tank 31, in order to prevent scales from being formed on the heater 32 or 80 in accordance with complete drainage of water remaining in the heating tank 31.
  • preferred embodiments of the present invention provide a washing machine in which water is supplied into the water tub in a state of being heated by a heater included in a steam generating unit, and steam generated from the steam generating unit is also supplied into the water tub to heat the wash water in the water tub to a desired wash temperature. Accordingly, the washing machines of preferred embodiments of the present invention can rapidly increase the temperature of wash water, thereby reducing the overall wash time, as compared to conventional washing machines.
  • water remaining in the heating tank is completely drained after completion of the steam generating operation. Accordingly, where the heater is installed within the heating tank, it is possible to prevent the heater from being maintained in a state of being dipped in water. Also, the heater may be installed outside the heating tank so that it may not come into contact with water. In either case, it is possible to prevent scales from being formed on the heater, and thus, to prevent a degradation in the performance of the heater.
