And a heat exchanger (84) for heating the blown air to produce a high-temperature dry air.

The hot air supply unit 80 supplies hot air to the laundry during drying of the laundry to dry the laundry. In addition, high temperature hot air may be sprayed on the laundry stored in the drum 30 to improve the contaminant binding force of the functional detergent penetrated into the laundry.

Meanwhile, the above-described water supply unit 50 and the discharge unit 70 may be additionally configured in the existing general laundry apparatus 100. That is, the laundry apparatus 100 that performs the washing using the existing washing water may additionally perform the washing using the functional detergent. Therefore, for the general configuration of the washing apparatus 100, since the subject matter of the present invention may be obscured, the detailed description thereof will be omitted.

Accordingly, the operation of the washing apparatus according to the present invention will be described in detail by way of examples. Each element and reference numeral mentioned below should be understood with reference to the above description and drawings.

First, the control unit 90 operates the water supply unit 50 as the user operates the operation panel 14 of the washing apparatus 100 to proceed with washing. The functional detergent is injected into the laundry loaded on the drum 30 by the injection nozzle of the water supply unit 50 (step S110).

The functional detergent injected therein penetrates the laundry. In this case, in order to increase the permeability of the functional detergent, the drum 30 on which laundry is loaded may be rotated at a predetermined first speed (about 10 to 60 rpm). In addition, the rinsing water supplied through the rinsing water supply line 54 and the functional detergent stored in the detergent storage tank 52 are mixed / diluted and sprayed by the spray nozzle 56 to increase the permeability of the functional detergent.

Then, when the injection of the functional detergent is completed, the control unit 90 rotates the drum 30 at a predetermined second speed (about 60 ~ 300rpm) to combine the functional detergent and contaminants of the laundry to proceed with the laundry ( Step S120).

In this case, the controller 90 may rotate the drum repeatedly in one direction and in a direction opposite to the one direction to activate the combination of the functional detergent and the contaminant. At this time, the functional detergent penetrated into the laundry is used in a significantly smaller amount than the conventional washing machine using the wash water. Therefore, it is possible to save the washing water by using a small amount of washing water compared to the existing washing apparatus.

On the other hand, the control unit 90 operates the steam spray unit 60 to improve the bonding between the functional detergent penetrated into the laundry and the contaminants of the laundry (step S130). Steam generated by the steam generator 64 of the steam injection unit 60 is injected to the laundry loaded on the drum through the steam injection nozzle (66). The hot steam is sprayed on the laundry, and thus the binding property between the contaminants of the laundry and the functional detergent penetrated into the laundry is activated.

At this time, the drum 30 loaded with laundry may maintain a state in which the laundry is rotated at a predetermined speed. Accordingly, the steam injected into the laundry may penetrate into every corner of the laundry flowing by the rotation of the drum 30 to further improve the bonding property between the contaminants of the laundry and the functional detergent penetrated into the laundry.

Meanwhile, the controller 90 may operate the hot air supply unit 80 together with the operation of the steam spray unit 60 to supply steam and hot air into the drum simultaneously or separately. This hot air can be supplied to the laundry of the drum 30 by heating the air circulating inside the drum by the drying duct 81 by the heat exchanger 84. At this time, the hot air supplied by the hot air supply unit may activate the combination of the contaminants of the laundry and the functional detergent, such as steam.

Subsequently, the controller 90 checks whether the washing is finished by a preset setting, and when washing is not completed, repeatedly performs the above-described processes (steps S120 and S130), and when washing is completed, the washing machine penetrates into the laundry. A process of separating the functional detergent is carried out (step S140).

As described above, when the washing of the laundry using the functional detergent is completed, the controller 90 rotates the drum 30 at a high speed (2500 to 3500 rpm) to separate the functional detergent penetrating into the laundry (step S150).

On the other hand, the functional detergent penetrated into the laundry and combined with the contaminants is released to the outside of the drum by centrifugal force in accordance with the high speed rotation of the drum 30 as described above, and at the same time to the outside of the tub by the vacuum suction input of the discharge part 70. Inhaled and discharged.

After the discharge of the functional detergent is completed, the control unit 90 operates the water supply unit 50 to supply the rinsing water to the laundry, and rotates the drum 30 to rinse the residual functional detergent and contaminants remaining in the laundry. The rinsing is performed and discharged (step S160).

Finally, the controller 90 rotates the drum 30 as the rinsing of the laundry is completed to dehydrate the residual rinsing water absorbed in the laundry to complete the washing (step S170).

On the other hand, the rinsing water and the rinsing water that has undergone the rinsing process in the above-described process (steps S160 and S170) are introduced through the drain bellows 73 connected to the tub 20 and the rinsing water is introduced into the drainage pump 75. By the discharge pipe 77 is discharged to the outside of the washing apparatus 100.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, The present invention may be modified in various ways. Therefore, modifications of the embodiments of the present invention will not depart from the scope of the present invention.
