AI Technical Summary

Technical Problem

In existing wide-width external drawer refrigerators, the rack and slide rails arranged side by side occupy too much space inside the refrigerator, affecting the usable volume of the drawers.

Method used

The design adopts a vertically arranged track rack, which overlaps the rack with the fixed slide rail in the horizontal direction and is connected to a synchronous rolling gear through a connecting shaft, thereby reducing the occupation of the horizontal space of the box cavity.

Benefits of technology

With the same cabinet volume, the effective usable volume of the drawer is increased, saving approximately 15mm of space.

Abstract

The utility model discloses a refrigerator of vertically arranged track rack, including box and drawer, be provided with the box cavity in the box, be provided with refrigerating system on the box, the both sides of box cavity are provided with fixed slide rail, the upper end or lower extreme of fixed slide rail is provided with rack, just rack and fixed slide rail overlap in horizontal direction, the both sides of drawer are provided with the dynamic slide rail of cooperation with fixed slide rail, the both sides of drawer are provided with the synchronous rolling gear of overlap with dynamic slide rail in horizontal direction, wherein two synchronous rolling gears are connected through a connecting shaft. Through the rack is arranged in the upper end or lower extreme of fixed slide rail, thereby fixed slide rail and rack are overlapped arrangement in horizontal direction, further reduce the occupation of the horizontal space of box cavity, thereby can make the effective use volume of drawer be bigger under the condition that the volume of box cavity is same, through the way, the unilateral drawer can save about 15mm space at least.

Claims

1. A refrigerator of vertically arranged track rack characterized in that, include: A box body (10) is provided with a box cavity (11) inside the box body (10). A refrigeration system is provided on the box body (10). Fixed slide rails (30) are provided on both sides of the box cavity (11). A rack (40) is provided at the upper or lower end of the fixed slide rail (30), and the rack (40) overlaps with the fixed slide rail (30) in the horizontal direction. The drawer (20) has movable slide rails (50) on both sides that cooperate with the fixed slide rail (30). The drawer (20) also has synchronous rolling gears (60) on both sides that overlap with the movable slide rails (50) in the horizontal direction. The two synchronous rolling gears (60) are connected by a connecting shaft (70).

2. A refrigerator with a vertically arranged rack and pinion mechanism as described in claim 1, characterized in that: The two side walls of the cavity (11) are provided with a mounting groove (111) along the front-back direction. The outer half of the fixed slide rail (30) is embedded and fixed in the mounting groove (111). The rack (40) is located below the fixed slide rail (30), and the rack (40) overlaps with the inner half of the fixed slide rail (30) in the horizontal direction. The rack (40) is located outside the mounting groove (111).

3. A refrigerator with a vertically arranged rack and pinion mechanism as described in claim 2, characterized in that: The top of the mounting groove (111) is higher than the side wall of the cavity (11), and the top edge of the mounting groove (111) is inclined to transition to the side wall of the cavity (11).

4. A refrigerator with a vertically arranged rack and pinion mechanism as described in claim 2, characterized in that: The fixed slide rail (30) includes a metal track body (31) and a plastic shell (32) for mounting the track body (31). A downwardly extending partition plate (321) is provided in the middle of the bottom surface of the plastic shell (32). The rack (40) is fixedly disposed on the inner side of the bottom surface of the shell, and the outer side of the rack (40) is simultaneously connected and fixed to the partition plate (321). The partition plate (321) abuts against the bottom edge of the mounting groove (111).

5. A refrigerator with a vertically arranged rack and pinion mechanism as described in claim 1, characterized in that: A shaft hole is provided at the lower part of the rear end face of the housing (10), and the connecting shaft (70) is inserted into the shaft hole.

6. A refrigerator with a vertically arranged rack and pinion mechanism as described in claim 5, characterized in that: The rear end face of the housing (10) is provided with an inlet groove that communicates with the shaft hole. The width of the inlet groove is smaller than the diameter of the shaft hole and the connecting shaft (70). The two sides of the inlet groove are elastic, so that elastic deformation can occur so that the width of the inlet groove is larger than the diameter of the connecting shaft (70).
