Description

Clothing processing apparatus {Fabric treating apparatus}

The present invention relates to an air flow path structure in a clothing treatment device.

Clothing processing equipment refers to all devices for managing or processing clothing, such as washing, drying, and removing wrinkles, at home or in a laundromat. For example, clothing processing devices include a washing machine for washing clothes, a dryer for drying clothes, a washer and dryer with both washing and drying functions, a refresher for refreshing clothes, and a steamer for removing unnecessary wrinkles from clothes. (Steamer), etc.

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

In addition, there is a known device that includes a hanger bar for hanging clothes in the treatment chamber and provides steam into the treatment chamber while the clothes are hanging, or supplies hot air by circulating air in the treatment chamber.

Clothes within the treatment space 10s may be treated in a variety of ways.

For example, hot air can be applied to clothing in the processing space 10s to dry the clothing. By supplying steam to the clothing within the treatment space (10s), wrinkles formed on the clothing can be smoothed out. The air and/or steam supplied within the processing space 10s affects the physical or chemical properties of the received clothing. Hot air or steam relaxes the tissue structure of clothing, smoothing out wrinkles, and odor molecules in the clothing react with the steam to remove unpleasant odors. Additionally, hot air and/or steam can sterilize bacteria living on clothing.

For example, dust from clothing in the processing space 10s can be removed through air circulation and filtering. Additionally, air outside the cabinet 10 may be supplied to the clothing to dehumidify the clothing in the processing space 10s or remove odor from the clothing. Additionally, an air freshener can be sprayed on the clothes in the treatment space 10s to make the clothes smell fragrant, or an anti-static agent can be sprayed to prevent static electricity from being generated in the clothes.

After rotating it sufficiently until it is constrained, it can be rotated (step rotation) by a certain rotation angle in the opposite direction. For example, when the motor shaft 83a is sufficiently rotated in the forward direction and the valve control unit 84 is rotated as much as possible in the first direction (FIG. 8A), the first valve 70a is in an open state, where the motor shaft (83a) is rotated in the reverse direction by a predetermined rotation angle so that the valve control unit 84 rotates in the second direction and both the first valve 70a and the second valve 70b are in a closed state (FIG. 8c).
