Description

clothes handling device

The present invention relates to a laundry treatment apparatus, and relates to a laundry treatment apparatus including a first drum and a second drum accommodating laundry.

[0002] A laundry treatment apparatus is a device that performs necessary treatment for the laundry, such as removing dirt from the laundry or drying it by putting laundry such as clothes and bedding into a drum.

When the laundry treatment apparatus is provided to remove contamination from laundry, the laundry treatment apparatus may perform processes such as washing, rinsing, spin-drying, and drying. It can be divided into a top loading method and a front loading method.

The laundry treatment apparatus may include a cabinet forming an exterior, a tub accommodated inside the cabinet, a drum rotatably mounted inside the tub and into which laundry is put, and a detergent supply device supplying detergent to the inside of the drum.

When the drum is rotated by the motor in a state in which wash water is supplied to the laundry stored in the drum, dirt attached to the laundry may be removed by friction between the drum and the wash water.

The detergent supply device has a detergent supply function to enhance washing effect. Here, the detergent means a material that enhances the washing effect, such as fabric detergent, fabric softener, and fabric bleach. As the detergent, powder (powder) type detergent and liquid (liquid) type detergent may be used.

Meanwhile, when the laundry treatment apparatus is provided to dry laundry, the laundry treatment apparatus may provide dry air to the laundry to remove moisture from the laundry.

The laundry treatment apparatus may include a cabinet, a drum rotatably provided inside the cabinet, and a heating means for heating or drying air supplied to laundry.

By supplying dry air to the laundry stored in the drum, moisture present in the laundry is evaporated and removed by the dry air, and moisture in the laundry can be removed.

On the other hand, many studies have been conducted to satisfy all the processing processes of various clothes required by users and to reduce the execution time for each processing process. For example, the laundry treatment apparatus may include a plurality of drums separated from each other and perform a plurality of treatment processes simultaneously by performing independent laundry treatment processes in each drum.

EP 2949801, a related document, discloses a laundry handling apparatus in which a drawer-type top-loader-type sub-drum is provided under a front-loader-type main drum. The user can perform the first treatment process of the clothes through the main drum and simultaneously perform the second treatment process independent of the first treatment process through the sub drum.

However, in the laundry treatment apparatus, the sub-drum has a smaller size than the main drum and can process a small amount of clothing, and there is a limitation in processing processes that can be performed, such as a drying process, due to spatial limitations.

In order to overcome the above problem, a plurality of drums are provided in a laundry treatment apparatus, and each drum has an equal size and is designed in an equal relationship with each other to perform independent laundry treatment processes.

Related document CN 102605586 discloses a laundry treatment device in which an upper first treatment device and a lower second treatment device are designed as a front loader type. In the laundry treatment apparatus, the user may simultaneously perform a plurality of laundry treatment processes by using the first treatment apparatus and the second treatment apparatus independently of each other.

In the laundry treatment device, an upper first treatment device is provided as a dryer capable of drying clothes, and a lower second treatment device is provided as a washing machine capable of washing clothes.
