AI Technical Summary

Technical Problem

The ice storage box of the existing refrigerator ice-making unit is pulled out at the same time as the freezer drawer, which leads to ice contamination and sticking problems, and the open structure is prone to ice contamination.

Method used

Design a slide rail system including a fixed rail and a moving rail. The ice storage box can be pulled out independently and separated from the freezer drawer by a push-spring component. The slide rail is equipped with a push-spring component. Pressing the near end of the ice storage box triggers the push-spring component, causing the moving rail to slide and the ice storage box to pop out from the bracket.

Benefits of technology

It enables independent operation of the ice storage box and the freezer drawer, avoiding ice contamination and sticking, enhancing the user experience, and maximizing the storage and retrieval space for frozen foods.

Abstract

This invention provides a slide rail, a drawer, and a refrigerator. The slide rail includes a fixed rail and a moving rail that slide together. The slide rail further includes a push-spring assembly disposed at the distal end of the fixed rail. The push-spring assembly includes a sleeve assembly and a push-spring connecting rod. The sleeve assembly includes a mounting groove, and a window portion is provided on the groove wall of the mounting groove, the window portion communicating with the mounting groove. The push-spring connecting rod is assembled at the proximal end of the sleeve assembly. The push-spring connecting rod includes a first body and a stop protrusion protruding from the first body. The first body is assembled in the mounting groove, and the stop protrusion is accommodated in the window portion. A moving rail locking member is disposed at the distal end of the moving rail. The proximal end of the moving rail locking member is pivotally connected to a protrusion at the distal end of the moving rail, and a limiting groove is provided at the distal end of the moving rail locking member. The moving rail retracts onto the fixed rail, and the stop protrusion is accommodated in the limiting groove.
