A locking projection 237 protruding therefrom is formed, so that the filter supporter 220 is hermetically fixed to the housing 230.

The operation of the lint filter assembly of the dry washing machine having the above configuration will be described.

When the laundry is put into the drum 120 and the tub 130 is supplied with washing water, and the clothes are locked to a predetermined level or more, the driving motor 110 starts to rotate by the operation of the control unit 500 and extends from the driving motor 110. The driven shaft 111 is rotated. The drive shaft 111 is fixed to the drum so that the drum 120 rotates.

As such, when the drum 120 rotates, the clothes are rotated along the inner diameter of the drum and fall into the washing water collected in the tub 130. When this series of steps is repeated, the wash water is drained and dehydration starts. In this case, the tub 130 is dehydrated using a centrifugal force by rotating the drum 120 at a high speed in the absence of washing water in the tub 130.

As such, when the drying of the dehydrated clothes is started, the motor 430 is rotated so that the blowing fan 420 starts to rotate. The blower fan 420 disclosed as described above moves air to the blower duct 400. At this time, since the heater 410 is installed in the blower duct 400, the air moved to the drum 120 is hot and dry.

Lint can be collected. Here, the filter support 220 and the housing 230 is inserted so as to have a constant inclination when the user is located in the front of the washing machine to give a convenience when detaching the filter support 220.

In addition, the lint filter assembly may be installed to the side of the washing machine as shown in FIG. In the structure as described above, the insertion port 232 of the housing 230 is installed on the side, the filter support 220 is a structure that can be detached to the side handle 250 is protruded into the cabinet 103, the filter paper from the side The earth 220 is detached.

The dry washing machine equipped with the lint filter assembly of the present invention can periodically collect the lint generated from the laundry after washing so as not to accumulate in the exhaust duct. Accordingly, the lint according to the long-term use of the conventional washing machine is accumulated in the exhaust duct and exhausted. In addition to preventing the closing of the duct, it also prevents the dry lint from igniting by heat.

And, since the filter support has a detachable structure, the user can remove the lint collected in the filter at any time, and when the filter support is coupled to the housing, the user can easily detach the lint. .

In addition, when the filter support is coupled to the housing, the airtight exhausted from the tub passes through the filter to maximize the filtering effect of the lint because the airtight of the filter support and the housing is maintained by the seal and the guide.

In addition, the lint filter assembly may not be attached or detached only to the upper plate of the washing machine. If necessary, the lint filter may be detached from the washing machine side by forming an insertion hole of the housing on the cabinet side.
