- Referring to
FIGS. 2 and 3 , the drum-type washing machine according to the present invention comprises amain casing 10 shaped with a square frame, a cylinder-type drum 20 installed inside themain casing 10 in which the laundry is put, a cylinder-type washing tank 22 installed inside themain casing 10, having dehydrating holes on the wall face thereof, a drivingmotor 23 provided below a lower unit of thedrum 20, rotating thewashing tank 22 forwardly or backwardly, to thereby performing operations to wash, rinse and dehydrate the laundry, and adoor 24 installed in front of themain casing 10, opening and closing themain casing 10. - Over the top of the

drum 20 are also provided a drying unit to dry the laundry after the dehydrating operation has been completed. The drying unit comprises a blowingfan 70 and a blowingfan duct 72 mounted on the top of thedrum 20, adischarging duct 80 mounted between the blowingfan duct 72 and anair inlet 21 a of thedrum 20 so as to allow them to communicate with each other, aheater 60 mounted inside thedischarging duct 80, acondensing duct 30 mounted between anair outlet 21 b of thedrum 20 and the blowingfan duct 72 so as to allow them to communicate with each other, and a coolingwater supplying unit 43 supplying cooling water into thecondensing duct 30 so that air which flows into thecondensing duct 30 from the inside of thedrum 20 is condensed. - The cooling
water supplying unit 43 comprises a coolingwater supplying tube 42 branched from thewater supplying valve 25, and a coolingwater jetting member 40 jetting the cooling water from the coolingwater supplying tube 42 to the inside of thecondensing duct 30. - With this configuration, air blown through the blowing
fan 70 is heated by theheater 60 while it is passing through thedischarging duct 80 and is then supplied to the inside of thedrum 20 through theair inlet 21 a, thereby heating and drying the laundry. The air at high temperature and high humidity generated in the course of drying the laundry flows into the inside of thecondensing duct 30 through theair outlet 21 b of thedrum 20, and water contained in the air at high temperature and high humidity flowing into the inside of thecondensing duct 30 is condensed by the cooling water jetted vertically downward through the coolingwater jetting member 40 in the course of being drawn into the blowingfan 70 after having passed thecondensing duct 30. - Inside the
condensing duct 30 are provided anelevation limiting projection 50 and a condensedwater collecting projection 51, whose shapes and installation positions may be modified in various ways, as necessary. - Below the lower part of the
drum 20 is provided a draining unit including adraining tube 28 and a drainingpump 29, so as to drain the water after washing inside thedrum 20. - As illustrated in
FIG. 4 , the drum-type washing machine according to the present invention comprises atemperature sensor 91 measuring a temperature of the condensed water condensed by the cooling water of the coolingwater supplying unit 43, and acontrol unit 90 controlling supply of the cooling water according to the temperature of the condensed water measured by thetemperature sensor 91. - The
temperature sensor 91 measures a temperature of the condensed water condensed by the cooling water of the coolingwater supplying unit 43 and discharged to the outside of thecondensing duct 30. It is preferable, but not necessary, that thetemperature sensor 91 is provided in the lower side of thecondensing duct 30, to measure the temperature of the condensed water discharged to a discharging unit (not shown) from thecondensing duct 30. - An established temperature to be compared with a temperature measured by the
temperature sensor 91 is established in thecontrol unit 90, wherein the established temperature refers to the highest temperature of the condensed water depicted inFIG. 6 . - The
control unit 90 controls the coolingwater supplying unit 43 so that the cooling water is supplied intermittently until the temperature measured in thetemperature sensor 91 reaches the established temperature, and also controls the coolingwater supplying unit 43 so that supply of the cooling water is continued after the temperature measured in thetemperature sensor 91 has reached the established temperature. - Hereinbelow, an operation to dry the laundry in the drum-type washing machine with the configuration described above will be described.
- As illustrated in
FIG. 3 , the air blown from the blowingfan 70 is heated by theheater 60 while it is passing through thedischarging duct 80, and then supplied into the inside of thedrum 20 through theair inlet 21 a. Accordingly, the laundry within thedrum 20 is heated and dried. - The air at high temperature and high humidity generated in the course of drying the laundry flows into the inside of the
condensing duct 30 through theair outlet 21 b of thedrum 20, and the air at high temperature and high humidity flowing into the inside of thecondensing duct 30 is drawn into the blowingfan duct 72 after having passed thecondensing duct 30. - When the air at high temperature and high humidity flowing into the inside of the
condensing duct 30 passes through thecondensing duct 30, the water contained therein is condensed by the cooling water supplied through the coolingwater supplying unit 43. At this time and with reference toFIG. 5 , the cooling water supplied through the coolingwater supplying unit 43 is intermittently supplied according to control by thecontrol unit 90 at operation S1. - As illustrated in
FIG. 6 , thecontrol unit 90 controls the coolingwater supplying unit 43 so that supply and interception of the cooling water can be repeated until the temperature of the condensed water measured by thetemperature sensor 91 reaches the established temperature, that is, during the A region. - By the way, condensation forms inside the
condensing duct 30 even while the cooling water is intermittently being supplied, as depicted in the A region ofFIG. 6 . - The condensed water is elevated by making use of an air current being elevated inside the
condensing duct 30 but its elevation is limited by colliding against theelevation limiting projection 50 and forming water drops on theelevation limiting projection 50. The water drops having formed on theelevation limiting projection 50 are dropped and collected in the condensedwater collecting projection 51, and the water drops collected in the condensedwater collecting projection 51 are scattered and elevated again by the upward air current, and then collided against theelevation limiting projection 50. This chain of processes is repeated. Since contact of the air current elevated with water is extended through these processes, condensation occurs within thecondensing duct 30 while the cooling water is being intercepted. - Next, the temperature of the condensed water measured by the
temperature sensor 91 is compared with the established temperature at operation S3. When the cooling water temperature measured by thetemperature sensor 91 reaches the established temperature as depicted inFIG. 6 , thecontrol unit 90 controls the coolingwater supplying unit 43 so that the cooling water having been supplied intermittently is continuously supplied at operation S5. - As depicted in
FIG. 6 , thecontrol unit 90 continuously supplies the cooling water to thecondensing duct 30 so as to allow the temperature of the condensed water to be lowered, after the temperature of the condensed water measured in thetemperature sensor 91 reaches the established temperature, that is, during the B region. - Thereafter, the
control unit 90 ascertains whether the drying operation is completed. If it is ascertained that the drying operation has been completed, thecontrol unit 90 stops supply of the cooling water. - In the drum-type washing machine according to the present invention as described above, if supply of the cooling water to the
condensing duct 30 and interception thereof are repeated, the condensed water temperature of thecondensing duct 30 is increased as the drying time is increased. Accordingly, the temperature of the air returned to the inside of thedrum 20 through the condensingduct 30 is also increased, thereby increasing the internal temperature of thedrum 20. - As the internal temperature of the
drum 20 is increased due to the intermittent supply of the cooling water to the condensingduct 30, an efficiency of vaporizing the water in the laundry can be improved and the drying time can be shortened. In addition, the amount of the cooling water consumed can be reduced. - In the above-described embodiment, the present invention has been applied to the condensing
duct 30 as illustrated inFIG. 3 . However, the present invention is not limited to this, but can be applied various types of condensing ducts. The present invention may also be applied to a condensingduct 130 illustrated inFIG. 7 . - The condensing
duct 130 illustrated inFIG. 7 comprises anair inlet 132 through which internal air of the drum flows, a condensingunit 134 through which the air flowing through theair inlet 132 passes, and anair outlet 136 through which the air having passed through the condensingunit 134 is discharged. - The present invention has been described with reference to a drum-type washing machine, but can also be applied to a drying machine.
- As described above, in a washing machine consistent with the present invention, the consumption amount of the cooling water can be reduced. In addition, the drying efficiency of the laundry can be improved and the drying time of the laundry can be shortened.
- Although a few exemplary embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
