FIG. 2 is a vertical sectional view of a drawer of a vacuum chamber of a refrigerator according to the present invention;

in the drawings, the components represented by the respective reference numerals are listed below:

1-refrigerator body, 2-vacuum chamber, 21-pressure release valve, 22-ultrasonic distance sensor, 3-vacuum chamber drawer, 31-annular elastic sealing strip, 4-air pump, 41-air extraction pipeline and 42-one-way valve.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "open hole", "upper", "middle", "length", "inner", etc. indicate positional or orientational relationships and are merely for convenience of description and simplicity of description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

Referring to fig. 1-2, the present invention relates to a vacuum chamber drawer of a refrigerator, which comprises a vacuum chamber 2 and a vacuum chamber drawer 3 installed in a refrigerator body 1; the vacuum chamber drawer 3 is arranged in the vacuum chamber 2 in a matching way; the vacuum chamber 2 is communicated with an air pump 4 outside the vacuum chamber 2 through an air pumping pipeline 41; the air extraction pipeline 41 is provided with a one-way valve 42; a pressure release valve 21 is arranged at the upper part of the vacuum chamber 2;
