It should be noted that the processing chamber 1 of the present embodiment is provided in a cylindrical structure.

In this embodiment, the laundry treatment apparatus further includes an inductive sensing unit, a detecting unit 3, and a control unit 4, wherein the inductive sensing unit includes a first electrode plate formed by the equipotential body 2, and a second electrode plate formed by the processing chamber 1, the equipotential body 2 is connected to a ground (GND ground in this embodiment), and the laundry in the processing chamber 1 is a part of the dielectric of the inductive sensing unit. The first electrode plate and the second electrode plate are both electrically connected to the detection unit 3, and the detection unit 3 is also connected to the ground terminal. The detecting unit 3 can detect the variation of the signal of the inductive sensing unit (the specific detecting mode is the prior art, for example, the detecting unit 3 sends a fixed frequency signal to the second electrode plate, so that the signal between the first electrode plate and the second electrode plate changes, the detecting unit 3 can obtain the variation of the signal of the inductive sensing unit and output the signal to the control unit 4, and the humidity of the clothes can be reduced along with the continuous drying, so that the dielectric constant of the dielectric of the inductive sensing unit can be changed, and the variation of the signal of the inductive sensing unit can be changed (the specific principle can refer to self-capacitance).
