Refrigerator with external vacuum freshness retaining device

Abstract

The invention discloses a refrigerator with an external vacuum freshness retaining device. The refrigerator comprises a refrigerator body. A vacuum pump is arranged in a compressor chamber and is connected with a refrigerator body connector by a refrigerator body pipeline, the refrigerator body pipeline is positioned in a refrigerator body wall, and the refrigerator body connector is positioned in a refrigerator body wall which faces a door; a switch of the vacuum pump is positioned on the surface of the refrigerator body or the surface of a door of a refrigerating chamber or the surface of a door of a freezing chamber; a draw-off connector, a door pipeline and a door connector are arranged in the door of the refrigerating chamber, the door pipeline is connected with the draw-off connector, and the door connector is connected with the door pipeline; the draw-off connector is exposed on the outer surface of the door of the refrigerating chamber; the door connector corresponds to the refrigerator body connector; a flexible connector is connected with the door connector or the refrigerator body connector and extends out of the surface of the door or the surface of the refrigerator body. The refrigerator has the advantages that the refrigerator is simple in structure, the door of the refrigerator does not need to be opened in service procedures, various vacuum pumping components do not occupy spaces in the refrigerating chamber and the freezing chamber, accordingly, the refrigerator brings convenience for users during vacuum pumping operation, the door of the refrigerator can be prevented from being frequently opened, and food contamination due to frequent opening of the door of the refrigerator can be prevented.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator for food preservation. Background technique [0002] Vacuum preservation is a mature food preservation technology. Its principle is to use vacuum to quickly form a low-oxygen and low-bacteria environment, which greatly delays the ripening and aging process of fruits and vegetables and prolongs the storage period. [0003] European patent EP0405680A2 discloses a vacuum preservation box arranged in a refrigerator compartment of a refrigerator, and the vacuum preservation box is connected with a door body. Its design limitation is: if the refrigerator door is opened, the vacuum crisper must be inflated and released, and the user has no other choice; if the user only wants to open the refrigerator door without releasing the vacuum crisper, this design cannot achieve Requirements, can not meet the needs of consumers; this vacuum preservation box has taken ...

AI Technical Summary

Problems solved by technology

Its design limitation is: if the refrigerator door is opened, the vacuum crisper must be inflated and released, and the user has no other choice; if the user only wants to open the refrigerator door without releasing the vacuum crisper, this design cannot achieve Requirements, can not meet the needs of consumers; this vacuum preservation box occupies the entire space of the refrigerator, and the user cannot use the refrigerator for other refrigeration purposes

But its design limitation is: if you want to vacuum the vacuum preservation box, you must open the refrigerator door to operate

In addition to accommodating the compressor, there is still space in the compressor room, but the space in the compressor room has not been effectively used at present
