Problems solved by technology

[0003] Conventionally, the refrigerator prolongs the life of food by adjusting the temperature and humidity, but only by adjusting the temperature and humidity can not hypnotize food (metabolism speed is extremely low), especially fresh fruit, it can only slow down its metabolism, which is far from modern Human requirements for food freshness and durability
[0004] More advanced, add a vacuum fresh-keeping device or a quick-cooling fresh-keeping device in the refrigerator freezer. By adding these two fresh-keeping devices, the fresh-keeping effect of the refrigerator is better than that of a conventional refrigerator, but it still cannot achieve the effect of hypnotic food
[0005] It is known that replacing the air in the food preservation environment with nitrogen and other inert gases can achieve the hypnotic effect of fresh fruits, and increasing the oxygen content in the food preservation environment can achieve the effect of keeping alive living things such as shrimp and fish, greatly Improve the fresh-keeping life of food, but the existing refrigerators do not have the device and method to control the internal gas composition

Embodiment 1

[0057] see Figures 1 to 4 , the present invention provides a fresh-keeping drawer 100, comprising a drawer body 1, the drawer body 1 is provided with a storage compartment 10 for storing food, and the storage compartment 10 is an openable sealing structure.

[0058] Specifically, the drawer body 1 includes a cover body 11, a box body 12 and a door body 13, and the box body 12 can move relative to the cover body 11 in the depth direction of the refrigerator to open or close the storage compartment 10. The door body 13 is arranged on the outer side of the refrigerator in the depth direction for heat preservation. The sealing structure includes a sealing ring 14 arranged on the box body 12 and a pressing mechanism (not shown) arranged on the cover body 11. When the storage compartment 10 is closed, the pressing mechanism presses the sealing ring 14 to ensure that the storage compartment is closed. 10 seals.

[0059] In this embodiment, the inside of the drawer body 1 is furthe...

Abstract

The invention discloses a control method for gas concentration in a freshness-retaining drawer. The control method comprises the following steps: acquiring current freshness-retaining gas concentration in a storage room, and comparing the acquired current freshness-retaining gas concentration with a preset threshold value to determine whether to input freshness-retaining gas into the storage room or not; or adopting a timing input method to control whether to input the freshness-retaining gas into the storage room or not. According to the control method, the freshness-retaining gas is selectively input into the storage room, so that the freshness-retaining gas concentration in the storage room can be controlled to be higher than target concentration, thereby greatly prolonging the freshness-retaining service life of food; and meanwhile, economical efficiency of the freshness-retaining gas is also taken into consideration.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping in refrigerators, in particular to a method for controlling gas concentration in a fresh-keeping drawer. Background technique [0002] With the acceleration of the pace of life and the improvement of the quality of life, people put forward higher and higher requirements for the durability and freshness of food preservation. [0003] Conventionally, the refrigerator prolongs the life of food by adjusting the temperature and humidity, but only by adjusting the temperature and humidity can not hypnotize food (metabolism speed is extremely low), especially fresh fruit, it can only slow down its metabolism, which is far from modern People's requirements for food freshness and durability. [0004] More advanced, vacuum fresh-keeping device or quick-cooling fresh-keeping device are added in the freezer compartment of the refrigerator. By adding these two fresh-keeping devices, the fresh-keeping ef...
