Document Type and Number:
WIPO Patent Application WO/2019/105476
Kind Code:
A1
Abstract:
A refrigerator and a drawer assembly thereof. The drawer assembly comprises: a drawer (20), whereof each of outer walls (201, 202) on the left and right sides is provided with an upper guide piece (210) and a lower guide piece (220) of which the bottom edges incline downwards from back to front; two support assemblies (10) respectively fixed to the left and right sides of a storage compartment, each support component comprising a support (100) having an upper sliding groove (150) and a lower sliding groove (140), the lower sliding groove (140) having a front vertical section (141), a horizontal section (142), and a rear vertical section (143); connecting members (300) each having, on front and rear ends, a front guide column (310) extending into the lower sliding groove (140) and a rear guide column (320) extending into the upper sliding groove (150); and elastic components which apply a pre-tightening force on the connecting member (300). When the drawer (20) is moved backward for closing, the upper guide pieces (210) press the front guide columns (310) downwards while moving backward, so that the front guide columns (310) leave the front vertical sections (141), enter the horizontal sections (142) and abut against the fronts of the lower guide pieces (220) to push the drawer (20) backward under the action of the elastic pre-tightening force; when the drawer (20) is moved forward for opening, the lower guide pieces (220) push the front guide columns (310) forward such that the front guide columns are stuck into the front vertical sections (141); when the drawer (20) is in an abnormal opening state, the drawer (20) is moved backward, and the lower guide pieces (220) press the front guide columns (310) downward while moving backward, so that the front guide columns enter the vertical sections (143) to allow the lower guide pieces (220) to cross over the front guide columns (310), and the front guide columns (310) are relocated in front of the lower guide pieces (220).
