- the steam generating unit 50 supplies steam into the washing tub 11 through the steam supplying pipe 44 . While the steam is supplied, the control unit 70 controls the temperature sensor 73 of the washing tub 11 to sense the temperature of the washing tub 11 ( 97 ), and determines whether the interior of the washing tub 11 is sufficiently heated to a temperature predetermined by a user or when steam supplying time predetermined by the user elapses ( 98 ). This determination depends on the steam supplying condition selectively inputted by the user (for example, the temperature of the washing tub or steam supplying time).
- the steam supply is stopped. In the event that the temperature of the washing tub 11 does not exceed the predetermined level, or the predetermined steam supplying time does not elapse, the above steam supplying operation controlling process is repeated.
- the condensed water generated while drying laundry is supplied to the steam generating unit to generate steam, whereby the formation of scale in the steam generating unit is minimized.
- the external water supply source supplies water into the condensed water tank when the condensed water is not sufficient in the condensed water tank, whereby water is easily supplemented in the condensed water tank.
- the condensed water is reused in a steam supplying operation that can heat the water, steam the wet laundry and steam dry wrinkled laundry. It is also possible to use and reuse the condensed water, with almost the purity of distilled water, as a supply of water, heated or unheated, to the washing operation, such as during washing or rinsing, using the steam supply system and controlling heat supplied to the water by the steam unit.

-
FIG. 4 is a flow chart illustrating a process of controlling a drying operation of the washing machine according an embodiment of the present invention. As illustrated inFIG. 4 , thecontrol unit 70 controls themotor 14 to be driven based on a drying signal inputted through thesignal input unit 71 to rotate therotary drum 11. At the same time, thecontrol unit 70 controls thefirst heater 37 and theblower 36 of the dryingunit 30 and the outsideair blowing fan 38 to be operated to dry laundry (81). Specifically, hot air is circulated in a closed circuit formed by thewashing tub 11 and the first tofourth ducts heat exchanger 35, and the condensed water flows down the condensedwater guide pipe 39, and is then collected in thecondensed water tank 60. - While drying the laundry, the water level of the
condensed water tank 60 is sensed by the water level sensor 61 (82), the water level sensor determines whether the water level of thecondensed water tank 60 is higher than the predetermined highest level H (83). If the water level of thecondensed water tank 60 is higher than the predetermined highest level H, the secondwater draining valve 63 is opened to drain the condensed water out of the condensed water tank 60 (84). If the water level sensor determines that the water level of thecondensed water tank 60 is lower than the predetermined highest level H, the secondwater draining valve 63 is closed (85). Specifically, the secondwater draining valve 63 is opened to drain the condensed water out of the condensed water tank when the water level of thecondensed water tank 60 is higher than the predetermined highest level H while the laundry is dried, and the secondwater draining valve 63 is closed to collect the condensed water in thecondensed water tank 60 when the water level of thecondensed water tank 60 is lower than the predetermined highest level H while the laundry is dried. - While the laundry is drying, the degree of dryness of the laundry is sensed by the drying sensor 72 (86), and it is determined whether dryness is sufficient (87). If the drying
sensor 72 determines that the dryness is sufficient, the drying operation is finished. When it is determined that the dryness of the laundry is not sufficient, the above drying operation controlling process is repeated. - Meanwhile, the steam supply of the
washing tub 11 may be selectively used to heat the wash water and the laundry before the washing operation is performed or during the washing operation or to reduce wrinkles of the laundry after the drying operation is completed. -
FIG. 5 is a flow chart illustrating a process of controlling a steam supplying operation of the washing machine according to an embodiment of the present invention. As illustrated inFIG. 5 , thecontrol unit 70 controls thewater level sensor 61 of thecondensed water tank 60 to sense the level of the condensed water collected while the laundry is being dried based on a steam supplying signal inputted through the signal input unit 71 (91), and determines whether the water level of thecondensed water tank 60 is higher than the predetermined minimum level L (92). It should be noted that the predetermined minimum level L is not a level that indicates that there is no water in thecondensed water tank 60. The predetermined minimum level L is a level indicating that there is a minimum amount of water sufficient to generate steam in thecondensed water tank 60. - When the
control unit 70 determines that the water level of thecondensed water tank 60 is higher than the predetermined minimum level L, that indicates that there is a minimum amount of water sufficient to generate steam in thecondensed water tank 60, the secondwater supplying valve 24 is closed such that water is not supplied to the condensed water tank 60 (93). On the other hand, when thecontrol unit 70 determines that the water level of thecondensed water tank 60 is lower than the predetermined minimum level L, the secondwater supplying valve 24 is opened such that water is supplied from the external water supply source to the condensed water tank 60 (94). - When the water in the
condensed water tank 60 exceeds the predetermined minimum level L, thesecond heater 53 of thesteam generating unit 50 operates (95). Also, thewater supplying pump 42 of the steam-purposewater supplying unit 40 operates and the thirdwater supplying valve 43 is opened such that the condensed water is supplied from thecondensed water tank 60 to thesteam generating unit 50 to generate steam (96). As described above, only the condensed water, which has nearly the same purity as distilled water, is supplied to thesteam generating unit 50 when the water in thecondensed water tank 60 exceeds the predetermined minimum level L. Consequently, the formation of scale in thesteam generating unit 50 is minimized. When the water level of thecondensed water tank 60 is lower than the predetermined minimum level L, on the other hand, the secondwater supplying valve 24 is opened such that external water is supplied into thecondensed water tank 60, and thus, thecondensed water tank 60 supplies the water to thesteam generating unit 50. - The
steam generating unit 50 supplies steam into thewashing tub 11 through thesteam supplying pipe 44. While the steam is supplied, thecontrol unit 70 controls thetemperature sensor 73 of thewashing tub 11 to sense the temperature of the washing tub 11 (97), and determines whether the interior of thewashing tub 11 is sufficiently heated to a temperature predetermined by a user or when steam supplying time predetermined by the user elapses (98). This determination depends on the steam supplying condition selectively inputted by the user (for example, the temperature of the washing tub or steam supplying time). - When the temperature of the
washing tub 11 exceeds the predetermined level, or the predetermined steam supplying time elapses, the steam supply is stopped. In the event that the temperature of thewashing tub 11 does not exceed the predetermined level, or the predetermined steam supplying time does not elapse, the above steam supplying operation controlling process is repeated. - As apparent from the above description, the condensed water generated while drying laundry is supplied to the steam generating unit to generate steam, whereby the formation of scale in the steam generating unit is minimized.
- Furthermore, the external water supply source supplies water into the condensed water tank when the condensed water is not sufficient in the condensed water tank, whereby water is easily supplemented in the condensed water tank.
- In the above-described embodiments, the condensed water is reused in a steam supplying operation that can heat the water, steam the wet laundry and steam dry wrinkled laundry. It is also possible to use and reuse the condensed water, with almost the purity of distilled water, as a supply of water, heated or unheated, to the washing operation, such as during washing or rinsing, using the steam supply system and controlling heat supplied to the water by the steam unit.
- Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
