Abstract:
The present invention relates to the technical field of laundry; specifically provided is a laundry device, which aims to solve the problems that existing laundry devices have a complex structure when outside air is used to dry an outer drum, which is not conducive to simplified design of the product structure, and the air drying effect is limited and the air drying efficiency is extremely low. The laundry device of the present invention comprises a drum assembly, a valve assembly, a fan, and a ventilation pipeline, the ventilation pipeline directly connecting the drum assembly with the outside, the valve assembly comprising a blocking mechanism and a valve housing having an air intake cavity and an air outlet cavity, the air intake cavity and the air outlet cavity being arranged independently of one another, an air inlet pipeline connecting the outside with the drum assembly being connected to the air inlet cavity, an air outlet pipeline connecting the outside with the drum assembly being connected to the air outlet cavity, the fan being arranged on the air intake pipeline, and the blocking mechanism being arranged to be able to simultaneously block the air intake pipeline and the air outlet pipeline. The present invention can increase the discharge speed of moisture and improve the air drying effect and air drying efficiency, facilitating the overall structural layout of the product, and reducing the complexity of the product design.
