Problems solved by technology

[0003] However, there are some problems in the use of this kind of refrigerator: 1) In order to prolong the low-pressure state in the vacuum storage chamber as much as possible, the vacuum box, the nozzle connecting the vacuum pump and the vacuum box, etc. need to be equipped with complicated parts to achieve sealing, which causes manufacturing costs Increase a lot; 2) When storing and taking food, the user must first release the low-pressure state in the vacuum storage chamber, so the refrigerator must have an additional high-precision low-pressure release mechanism, which will also increase the manufacturing cost of the refrigerator

Embodiment 1

[0059] figure 1 Shown is a schematic structural view of the refrigerator provided in this embodiment, see figure 1 shown, this refrigerator includes:

[0060] storage room 11;

[0061] A gas storage tank 12 suitable for storing compressed gas with low oxygen concentration, and the gas storage tank 12 is used to fill the storage chamber 11 with gas with low oxygen concentration.

[0062] Each component is described in detail below.

[0063] In this embodiment, the storage room 11 is a storage room partially defined by an inner tank (not marked) and partly defined by a door (not marked) corresponding to the inner tank. The inner container can be an inner container of a refrigerating room, or an inner container of a freezing room or a zero-degree fresh-keeping room.

[0064] The gas storage tank 12 is used for storing the low oxygen concentration gas, and the source of the low oxygen concentration gas is the hypoxic gas source 13 . The hypoxic gas source 13 can be set as a p...

Embodiment 2

[0087] The refrigerator provided in the second embodiment and the method for keeping food in the refrigerator are roughly the same as those in the first embodiment. The difference is: if Figure 4 As shown, the storage compartment 11 is formed by a storage unit accommodated in the storage compartment, such as but not limited to a storage box 11'. to combine Figure 5As shown, the storage box 11' is provided with one or more exhaust holes 111' for discharging the gas inside to the storage room 11, preferably, the gas is discharged to the outside through the exhaust channel 17 of the storage room 11. . For storage boxes 11' of different volume sizes, the air vent 111' may have different sizes.

[0088] It can be seen that the storage chamber 11 in the first embodiment has a relatively large volume, so the gas storage tank 12 needs to have a relatively large volume or pressure bearing capacity. The volume of the storage box 11' in the second embodiment is small, so the demand...

Embodiment 3

[0090] The refrigerator provided in the third embodiment and the method for keeping food fresh in the refrigerator are roughly the same as those in the first and second embodiments. The difference is that the air storage tank 12 is placed in the cooled storage space in the refrigerator. The temperature in the cooled storage space is below room temperature, such as but not limited to a cold storage room such as Figure 6 As shown, it can also be other cooled storage spaces in the refrigerator. The advantage of the above scheme is that when the gas storage tank 12 fills the storage chamber 11 with low-oxygen-concentration gas, the low-oxygen-concentration gas has already been cooled, which can reduce energy consumption.

Abstract

Disclosed are a refrigerator and a food preservation method thereof. The refrigerator comprises a storage chamber and a gas storage tank; the gas storage tank is applicable to storing compressed gas of low oxygen concentration; the gas storage tank is used for charging the low oxygen concentration gas into the storage chamber. The low oxygen concentration gas helping store foods for a longer period of time is charged into the storage chamber of the refrigerator; required parts are simple, cost is low, low oxygen environment can be quickly provided for the storage chamber by the gas storage tank, and the requirement for food preservation is met.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a method for keeping food in the refrigerator fresh. Background technique [0002] A refrigerator is a household appliance that provides a low-temperature storage environment. The refrigerated or frozen low-temperature environment provided by it enables food, fruits and vegetables to be stored for a long time. Studies have shown that the length of food storage time is not only related to temperature, but also related to the air content or oxygen content in the storage container. Based on this, vacuum preservation technology came into being. The so-called vacuum preservation is to put food, such as fruits and vegetables, in a sealed container, and then take away at least part of the air in the container to form a low-pressure state, so that the amount of oxygen in the container is greatly reduced, and various microorganisms that cause food to rot and dete...
