The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

Referring to fig. 1 and 2, the refrigerator of the present embodiment has an approximately rectangular parallelepiped shape. The external appearance of the refrigerator is defined by a cabinet 100 defining a storage space and a door provided on the cabinet 100 to open or close the cabinet.

The cabinet 100 is generally open at the front side, and includes a sheet metal shell 110, a refrigerating inner container 120 disposed inside the sheet metal shell 110, and a freezing inner container (not shown) and an insulating layer (not shown) between the inner container and the shell, wherein the refrigerating inner container 120 defines a refrigerating chamber 130, and the freezing inner container defines a freezing chamber.

Unlike the prior art, the refrigerator of the present embodiment further includes a light refreshment module 200 for performing light refreshment on food in the refrigerating chamber 130.

Also included is an air circulation module 300 comprising an air compressor 310 and a gas feed line 320, an inlet end of the gas feed line 320 being in communication with an outlet end of the air compressor 310, the outlet end of the gas feed line 320 leading to an evaporator (not labeled) in the refrigeration system of the refrigerator. The air compressor 310 operation triggers the evaporator and light refresher module 200 operation.

The refrigerator is an air-cooled refrigerator, an evaporator is arranged in a refrigerating air duct in a back side heat insulation layer of a refrigerating liner 120, when a refrigerating system works, a fan in the refrigerating air duct is started, and the fan blows cold air near the evaporator into a refrigerating chamber 130 through the refrigerating air duct, so that the low temperature of the refrigerating chamber is realized.

After the light increasing and fresh keeping module 200 operates for a period of time, the illumination in the refrigerating chamber 130 keeps fresh, so that carbon dioxide used for food material photosynthesis in the refrigerating chamber 130 is gradually reduced, the effect of photosynthesis can be reduced, and the illumination fresh keeping effect of food materials is influenced.

The air circulation module 300 is arranged to solve the above problems, the air circulation module 300 is opened, the air compressor 310 pumps fresh air into the vicinity of the evaporator through the air supply pipeline 320, and the fresh air enters the refrigerating chamber through the refrigerating air duct, so that the content of carbon dioxide in the refrigerating chamber is increased, photosynthesis is enhanced, and the illumination effect is improved.

The air input through the air compressor 310 is ambient air, and if the ambient air is directly input into the refrigerating chamber 130, the temperature of the refrigerating chamber 130 is increased, which is not favorable for storing food materials at low temperature, and the refrigerating efficiency of the refrigerating system is reduced.

Therefore, in the present application, the air input by the air compressor 310 is guided to the vicinity of the evaporator, and the air compressor 310 is activated to trigger the refrigeration system to be opened in a related manner, so that the normal temperature air is mixed with the cold air near the evaporator, and then the mixture is cooled and input into the refrigerating chamber 130, thereby avoiding the above problems.

When the air compressor 310 is started, the light freshness increasing module 200 is also triggered to be opened in a related manner, so that the light freshness increasing effect is improved.

After the air compressor 310 is turned on for a certain time (e.g., 15 min), the air compressor 310 is automatically turned off.

In some embodiments of the present application, referring to FIG. 1, an air compressor 310 is provided within a compressor compartment of a refrigerator.

In some embodiments of the present application, referring to fig. 2 and 3, the light freshening module 200 is disposed at the top of the refrigerating compartment 130, and the light freshening module 200 includes a light guide plate 220 and a plurality of light sources 210.

When the light increasing and fresh keeping module 200 works, the light source 210 emits light capable of promoting the food materials to perform photosynthesis, and the light increasing and fresh keeping module 200 is arranged at the top of the refrigerating chamber, so that the light emitted by the light source 210 is downwards guided to the refrigerating chamber 130 through the light guide plate 220, the illumination effect in the refrigerating chamber 130 is improved, the photosynthesis is enhanced, and the illumination fresh keeping effect of the food materials is improved.

After the light increases bright module 200 work a period, near the temperature of light source 210 can rise, and the temperature in the walk-in 130 is lower again, and the difference in temperature can lead to near the production condensation of light source 210, receives the influence of humidity in the walk-in 130 simultaneously also can produce the condensation, and the condensation can influence the illumination effect, reduces fresh-keeping effect.
