AI Technical Summary
⚠Technical Problem
Existing refrigerator drawers require a sensor switch for each drawer, resulting in a complex structure and high manufacturing costs.
⚗Method used
By using a combination of gear and rack components, the status of multiple drawers can be sensed through a single inductive switch. The opening or closing of the drawers is sensed by the combination of a bar magnet and a reed switch.
🎯Benefits of technology
The design simplifies the structure, reduces manufacturing costs, and maintains the sensitivity and accuracy of the drawer status sensor.

Abstract
The application relates to the technical field of household appliances, in particular to a refrigerator. The refrigerator comprises a refrigerator body; at least one drawer group, each drawer group comprising at least two drawers; a gear assembly rotatably connected to one drawer; a rack assembly connected to the remaining drawers and corresponding matched with the rack assembly, wherein the gear assembly and the rack assembly can synchronously move relatively when the drawers move relatively; a starting piece connected to the gear assembly and capable of changing state under the action of the relative movement of the gear assembly and the rack assembly; and an induction assembly connected to the refrigerator body and capable of sensing different states of the starting piece to respond to the opening or closing of the drawers. The refrigerator provided by the application can share one induction switch in one drawer group, thereby reducing the manufacturing cost and simplifying the structural design.
