Embodiment 1

[0014] Embodiment 1: as figure 1 Shown is a vacuum fresh-keeping device for a refrigerator, the vacuum fresh-keeping device is arranged in the refrigerating box of the refrigerator, and the vacuum fresh-keeping device includes at least one vacuum box body 001, a vacuum generating device for vacuuming the vacuum box body 001, and controlling vacuum extraction and holding The vacuum control device, the vacuum generating device includes a vacuum pump 002 and one end connected to the vacuum pump 002, and the other end is connected to the vacuum box 001 in a vacuum pipeline 003. The vacuum control device is a control on-off valve body arranged on the vacuum pipeline 003. A conduction valve 004 is arranged on the pipeline 003, and the conduction valve 004 is preferably an electromagnetic stop valve. The vacuum pipeline 003 at the back end of the conduction valve 004 is also provided with a bypass pipeline 005 communicating with the atmosphere. The bypass pipeline 005 is provided with...

Embodiment 2

[0015] Embodiment 2: Referring to Embodiment 1, the conduction valve 004 is preferably a one-way valve. When the vacuum pump 002 is working, the two ends of the one-way valve are under positive pressure difference, the one-way valve is opened, and the air passes through the one-way valve The flow flows out to the vacuum pump 002. When the vacuum pump 002 stops and the electromagnetic cut-off valve on the bypass pipe 005 is opened, the check valve is closed due to the reverse pressure difference at both ends of the check valve, so as to maintain the vacuum degree in the vacuum pump 002.

Abstract

A vacuum refreshing device for a refrigerator belongs to the field of vacuum refreshing. The vacuum refreshing device is arranged in a refrigerating box of the refrigerator, and comprises at least one vacuum box, a vacuum generation device for vacuumizing the vacuum box, and a vacuum control device for controlling pumping and preserving of vacuum. Through the arrangement of the vacuum generation device and the vacuum control device in the refrigerator, the degree of vacuum in the vacuum box is controlled well, so that food is isolated from air to be in negative-pressure and hypoxia environment, which prolongs the food refreshing time.

Description

technical field [0001] The invention relates to the field of vacuum fresh-keeping devices, in particular to a vacuum fresh-keeping device for a refrigerator. Background technique [0002] The existing anti-corrosion and fresh-keeping technologies for refrigerators are mainly divided into two types: (1) low-temperature refrigeration and fresh-keeping, and (2) using precious metals to decompose harmful gases in the air to achieve anti-corrosion and fresh-keeping effects. The above two commonly used anti-corrosion and fresh-keeping technologies have a short anti-corrosion and fresh-keeping time, usually no more than one week, and the effect is poor, which cannot meet the needs of meat, fruit and vegetable fresh-keeping, and needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a way to isolate food from the air and place it in a negative pressure and low-oxygen environment, so as to reduce the surf...
