Description

Stacked laundry treatment equipment

technical field

The present invention relates to the field of clothes treatment devices, and in particular, to a fixing structure for stacked clothes treatment devices and a stacked clothes treatment device.

Background technique

In modern life, washing machines have become an essential household electrical appliance. Some families will further purchase clothes dryers for the needs of drying clothes after washing, or families have multiple washing machines to meet the needs of adults and children. The need for separate washing.
