Problems solved by technology

After the air in the box is evacuated, it must bear the atmospheric pressure, so its material must have a strong ability to resist pressure, resulting in a relatively high price for the drawer
In particular, refrigerators generally use multiple drawers, so that the overall price of the refrigerator will increase a lot accordingly.

Embodiment 1

[0028] Such as image 3 As shown, it is a structural diagram of a refrigerator fresh-keeping system according to Embodiment 1 of the present invention. As shown in the figure, the refrigerator fresh-keeping system includes a refrigerator drawer 310 and an oxygen removal device 340 . Wherein, the refrigerator drawer 310 has an air inlet 320 and an air inlet 330 respectively, and the oxygen removal device 340 is connected to the air inlet 330 through a first pipeline 350 , and is connected to the air inlet 330 through a second pipeline 360 ​​. The refrigerator drawer 310 includes a drawer body 311 and a cover plate 312 . Wherein, the cover plate 312 is fixed in the refrigerator, and the drawer body 311 is movable relative to the cover plate 312 . It should be noted that in the embodiment of the present invention, one refrigerator drawer 310 is used as an example for description, and in other embodiments, multiple refrigerator drawers may be included, and these refrigerator dra...

Embodiment 2

[0032] Such as Figure 4As shown, it is a structural diagram of a refrigerator fresh-keeping system according to Embodiment 2 of the present invention. As shown in the figure, the difference between this embodiment and the first embodiment above is that the refrigerator fresh-keeping system of this embodiment further includes a fourth pipeline 410 , a second valve 420 , a second pump 430 and a pressure sensor 440 . Wherein, the fourth pipeline 410 is connected with the third pipeline 344 , the second valve 420 is arranged on the fourth pipeline 410 , and the second pump 430 is connected with the fourth pipeline 410 .

[0033] In this embodiment, the controller is also connected to a pressure sensor 440 for detecting the pressure inside the refrigerator drawer 310 . After the pressure in the refrigerator drawer 310 is lower than a preset value (referred to as the second preset value in the present invention), the controller opens the second valve 420 and the second pump 430 to...

Abstract

The invention provides a refrigerator refreshing system which comprises a refrigerator drawer, an air aspirating hole, an air inlet and an oxygen removing device, wherein the air aspirating hole and the air inlet are arranged on the refrigerator drawer; the oxygen removing device is connected with the air aspirating hole through a first pipeline and connected with the air inlet through a second pipeline, and air in the refrigerator drawer flows into the refrigerator drawer after flowing through the oxygen removing device. Because the refreshing is carried out not by adopting a vacuum manner in the embodiment of the invention, materials made of the drawer do not need very strong stress tolerance, the manufacture cost of the drawer can be greatly lowered while the refreshing effect is ensured, thus the manufacture cost of the refrigerator is finally lowered.

Description

technical field [0001] The invention relates to the technical field of household appliance manufacturing, in particular to a refrigerator fresh-keeping system and a refrigerator having the same. Background technique [0002] At present, the fresh-keeping methods of refrigerators on the market include photosynthetic fresh-keeping, VC-induced fresh-keeping, zero-degree fresh-keeping, ion sterilization and fresh-keeping, vacuum fresh-keeping, etc. Since bacteria cannot grow in a vacuum environment, vacuum preservation works best compared to other preservation methods. [0003] Such as figure 1 Shown is the structural diagram of the prior art vacuum preservation device. The vacuum preservation device includes a vacuum pump 110 , a valve 120 , a box body 140 with a drawer, and a cover plate and a sealing ring 130 covering the box body 140 . After the air in the box is evacuated, it must bear atmospheric pressure, so its material must have strong compression resistance, resulti...
