PASSIVE DEVICE, WASHING TUB, WASHING TUB ASSEMBLY, AND TUB-IN-TUB WASHING MACHINE

摘要

A passive device (10), a washing tub (500, 1100, 2100), a washing tub assembly (20, 21, 22, and 2200), and a tub-in-tub washing machine. The passive device (10) comprises a housing (100), a first detection member (200) and a second detection member (300); the first detection member (200) and the second detection member (300) are both disposed in the housing (100); one of the first detection member (200) and the second detection member (300) is a magnetic member, and the other of the first detection member (200) and the second detection member (300) is a sensing module; the first detection member (200) and the second detection member (300) generate relative movement and generate inductive power when the housing (100) moves in a preset direction.
