Abstract

The invention relates to an automatic telescopic device for a refrigerator drawer. The refrigerator drawer, a lower layer driving guiding portion, a middle layer moving portion and an upper layer moving portion are included. The lower layer driving guiding portion is fixedly connected to the bottom of a refrigerator box inner container through a bottom plate; the middle layer moving portion is arranged above the lower layer driving guiding portion; the upper layer moving portion comprises a supporting plate and is arranged above the middle layer moving portion; and the upper plane of a hood shell of the supporting plate is connected with the bottom of the refrigerator drawer. According to the automatic telescopic device for the refrigerator drawer, according to the relative movement principle, two mechanisms are adopted for correspondingly making the drawer of a refrigerator move by one distance, and the sum of the two distances meets the distance requirement of moving of the refrigerator drawer. The automatic telescopic device for the refrigerator drawer is convenient to use, movement of each mechanism is controlled through a motor, and the automatic telescopic function of the refrigerator drawer is achieved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an automatic telescopic device for a refrigerator drawer. Background technique [0002] At present, most of the drawers of household refrigerators are manually extended and retracted, which is very inconvenient to use. Manually pulling the refrigerator drawers is often caused by uneven force during pulling, so that the refrigerator drawers are stuck in the refrigerator box and cannot be pulled, especially for large refrigerators. The refrigerator drawer is even more so. If the refrigerator drawer is designed as an automatic expansion and contraction device, due to the limitation of the space of the refrigerator box, there is no space to use a mechanism to move the refrigerator drawer out at one time. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned technical problems, the present invention provides an automatic telescopic device for a refrigerator dra...
