In this embodiment, the sensing assembly includes a reed switch 3 and an inductor, the reed switch 3 is connected to the refrigerator body, the inductor is electrically connected to the reed switch 3, specifically, the starting member 4 is a bar magnet, wherein a change in the state of the starting member 4 can trigger the reed switch 3 to open or close, so as to correspondingly realize that the inductor responds to the drawer opening or closing, the change in the angle of the bar magnet is utilized to realize the opening or closing of the reed switch 3, and the opening or closing of the corresponding reed switch 3 is realized through the inductor, so as to correspondingly realize the opening or closing of the sensing drawer.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
