In addition, the motor 50 is fixed to the inner bottom of the main body 10 to generate a driving force for rotating the drying drum 20.

The heater 60 is installed inside the hot air supply passage 91 to heat air flowing through the inside of the hot air supply passage 91.

At this time, the hot air supply passage 91 serves to guide the air flow so that the outside air is introduced into the drying drum 20 and discharged to the outside of the main body 10.

In addition, the blowing fan 70 is operated to discharge dry air flowing in the drying drum 10 to the outside of the main body 10, and is provided to communicate with the hot air discharge passage 92.

Hereinafter, the clothing drying process by the laundry dryer having the above-described configuration will be described in more detail.

First, laundry to be dried is introduced into the drying drum 20.

In this way, when the laundry is added and the drying stroke is performed, the heater 60 and the motor 50 are operated.

In addition, as the blower fan 70 is operated, external air introduced into the main body through the suction side of the hot air supply passage 91 is heated to pass through the heater 60, and the hot air is heated to the hot air supply passage. It is forced into the drying drum 20 through 91.

As described above, the hot air introduced into the drying drum 20 is dried by the blowing force of the blower fan 70 to dry the wet laundry and then discharged to the outside of the main body 10 through the hot air discharge passage 92. do.

In this process, the stirring piece 21 protruding from the inner wall surface of the drying drum 20 is in contact with the laundry to prevent tangling between the laundry.

When the laundry is completely dried by repeatedly performing the above process, the door 40 is opened to discharge the laundry inside the drying drum 20.

In recent years, a study has been made to allow the laundry dryer not only to perform laundry drying but also to perform a role other than drying.

As an example, by providing a separate dry cleaning kit (kit) to enable the dry cleaning of the laundry using the laundry dryer, dry cleaning is possible at home as the dry cleaning kit.

Here, the dry cleaning kit includes a damping cloth that emits incense with a predetermined amount of steam when it is provided with high temperature heat, a packing bag for packing a predetermined amount of laundry and the damping cloth, and decontamination of laundry by manual labor. It is configured to include a decontaminant and a fouling absorbent pad.

Therefore, the decontamination of the laundry is performed by receiving the decontamination absorbent pad at the soiled area of the laundry and then applying the decontamination agent to the debris so that the decontamination is transferred to the decontamination absorbent pad. After the laundry is embedded in the packaging bag together with the damp cloth, the cleaning bag is operated by operating the laundry dryer in a state in which the packaging bag is sealed and put into the laundry dryer.

At this time, when the hot air is provided in the drum by the operation of the laundry dryer, the moisture and the fragrance contained in the damp cloth in the bag are evaporated, thereby refreshing the laundry in the bag.

However, the above-described dry cleaning process of the conventional laundry can not be performed by the laundry dryer itself because it can be performed in the laundry dryer only when a dry cleaning kit is provided.

In particular, since the packaging bag constituting the dry cleaning kit has a very small allowable capacity, only 3 to 4 dry shirts are dry cleaned, and thus, the cost for dry cleaning compared to the purchase cost of the dry cleaning kit is limited. The reduction of has a problem that was inevitable.

In addition, among the components of the above-described dry cleaning kit, the packaging bag requires a lot of precautions due to its material characteristics.

For example, when a hole or the like is generated in the packaging bag, it is not possible to use it, and at a very high temperature, the precautions that cannot be used because the packaging bag may melt are required.

In addition, the wet cloth constituting the above-described dry cleaning kit has a problem that the contact was made only locally with the laundry because it is only put in a specific area in the bag with the laundry.

That is, even when the drying drum is rotated, the dry cleaning is performed only in the local part of the laundry (the part into which the wet cloth was first put) because the position change of the damp cloth was not made.

The present invention has been made to solve the above problems of the prior art, and to provide a structure that allows dry cleaning for a large amount of laundry using a laundry dryer, and also to enable a smooth dry cleaning. have.
