The damper damper 300 includes a damper cylinder 310 and a damper rod 320. The upper end of the damper cylinder 310 is mounted on the cylinder 200 (up and down direction is indicated by an arrow A in FIGS. 1 and 2). The lower end of the damper rod 320 is mounted on the casing 100, and the upper end of the damper rod 320 is movably fitted in the damper cylinder 310 in the axial direction of the damper cylinder 310. When the cylinder 200 is displaced in the up and down direction, the damper rod 320 moves in the axial direction of the damper cylinder 310 in the damper cylinder 310, thereby achieving a shock absorbing function for the cylinder 200.

In some specific examples of the invention, as shown in FIGS. 1 and 2, the photosensor unit 400 includes a transmit receive region 410 and a reflective region 420.

The reflective area 420 of the sensing unit 400 does not move. At this time, the distance between the transmitting and receiving area 410 of the photo sensing unit 400 and the reflective area 420 changes, and the distance between the reflective area 420 and the transmitting and receiving area 410 changes, so that it can be calculated. The weight of the laundry.

Thereby, the reflection area 420 can be made stationary with respect to the damper rod 320 and the emission receiving area 410 is stationary with respect to the damper cylinder 310, so that the photoelectric sensor unit 400 can detect the stroke amount of the damper damper 300.

The emitter 411 and the receiver 412 are spaced apart on the damper cylinder 310. Thereby, the reflective region 420 can be facilitated to reflect the spectral signal emitted by the emitter 411 to the receiving member 412.
