A laundry device, comprising a barrel assembly, a valve assembly (5), and a fan (6), wherein the valve assembly comprises a blocking mechanism and a valve housing (51) which has an air intake cavity (511) and an air outlet cavity (512), the air intake cavity and the air outlet cavity are arranged independent of each other, the air intake cavity communicates with air intake pipelines (7, 8) that connect the outside with the barrel assembly, the air outlet cavity communicates with air outlet pipelines (9, 10) that connect the outside with the barrel assembly, the fan is provided on the air intake pipelines and/or the air outlet pipelines, and the blocking mechanism is arranged to be able to simultaneously block the air intake pipelines and the air outlet pipelines. Further relating to a valve assembly. According to the laundry device and the valve assembly, the air intake pipelines and the air outlet pipelines can be blocked at the same time, so that the dual blocking effects of blocking the entry of external dust and preventing foam overflow can be achieved. The structure is simple, the overall structure arrangement of products is facilitated, and the design complexity is reduced.
