Looking at the drying administration of the combined dry washing machine according to the present invention configured as described above are as follows.

In the drying stroke, the drum 52 is rotated, the circulation fan 54 and the drying heater 53 are turned on, and the cooling water is supplied through the cooling water supply devices 62 and 63.

When the drum 52 is rotated, the fabric m in the drum 52 flows inside the drum 52, and the air in the drum 52 is blown by the rotation of the circulation fan 54. It flows toward the through hole 56 of the drum (52).

The air moving toward the through hole 56 of the drum 52 is brought into contact with the cloth m to be converted into low temperature and humid air, and then the through the open hole 56 of the drum 52 and the drum 52. It flows between the tubs 51.

The moist air flowing between the drum 52 and the tub 51 comes into contact with the first and second condensation plates 61 and 71.

Meanwhile, the coolant supplied through the coolant valve 62 and the coolant hose 63 passes through the first coolant passage 65, cools the first condensing plate 61, and is discharged downward.

At this time, the humid air contacted with the first condensation plate 61 is deprived of heat to the first condensation plate 61, so that the moisture in the humid air is condensed on the first condensation plate 61, It is changed to air.

Low humidity air is sucked into the drying duct 55 and heated by the drying heater 53, and then circulated again into the drum 52.

In addition, the cooling water and the condensed water passing through the first cooling water passage 65 are discharged to the drain hose 81 through the lower side of the tub 51.

The cooling water and the condensed water discharged to the drain hose 81 are pumped by the drain pump 82 and are supplied to the second coolant passage 74 through the circulation duct 83.

Cooling water supplied to the second coolant passage 74 passes between the second condensing plate 71 and the inner wall of the tub 51, cools the second condensing plate 71, and then cools the water drain hose. It is discharged to the outside of the cabinet 50 through 72.

At this time, the wet air contacted with the second condensation plate 71 loses heat to the second condensation plate 71, so that the moisture in the humid air is condensed on the second condensation plate 71, and thus, It is changed to air.

Therefore, air drying the cloth m in the drum 52 is condensed by the first and second condensation plates 61 and 71 disposed on the left and right sides of the tub 51. Efficiency can be maximized.

In addition, since the cooling water and the condensate are recycled, the amount of the cooling water used can be reduced.

Drying washing machine according to the present invention configured as described above is provided with the first and second condensation plates to form the first and second cooling water passages on the left and right inner walls of the tub, respectively, the cooling water and the condensate passing through the first cooling water passage By circulating in the second cooling water passage, since the cooling water and the condensed water are recycled, the amount of the cooling water is reduced, thereby reducing the maintenance cost.

In addition, since the air drying the fabric is condensed in the left and right sides of the tub, there is an advantage that the condensation efficiency is improved.

In addition, since the condensation duct is eliminated, the flow resistance is reduced to shorten the drying time, and sufficient space can be secured between the back of the tub and the cabinet, thereby increasing the volume of the drum to increase the washing / drying capacity. There is an advantage to this.
