Description

Clothing treating apparatus {Fabric treating apparatus}

The present invention relates to an air flow path structure of a clothes treatment apparatus.

The clothes processing device refers to all devices for managing or processing clothes, such as washing, drying, and wrinkle removal of clothes at home or in a laundry. For example, the clothes processing apparatus includes a washing machine for washing clothes, a dryer for drying clothes, a washing machine and dryer having both washing and drying functions, a refresher for refreshing clothes, and a steamer for removing unnecessary wrinkles from clothes. (Steamer) and others.

More specifically, the refresher is a device for making clothes more pleasant and fresh, and performs functions such as drying clothes, supplying fragrance to clothes, preventing static electricity generation of clothes, or removing wrinkles from clothes. A steamer is a device that removes wrinkles from clothes by supplying steam to clothes in general, and unlike a general iron, a hot plate does not touch clothes, so it delicately removes wrinkles from clothes. There is known a clothing treatment apparatus that has both functions of a refresher and a steamer, and performs functions such as removing wrinkles and odors of clothes stored therein by using steam and hot air.

In addition, there is known a device that includes a hanger rod on which clothes are hung in the processing chamber, and supplies steam into the processing chamber while the clothes are hung, or supplies hot air while circulating air in the processing chamber.
