Still referring to fig. 3 and 4, the sterilization assembly includes a light emitting source 31 and a layer of sterilization material 32.

The sterilizing material layer 32 with photocatalytic activity is coated on the inner wall of the ventilation air duct and the outer surface of the air dispersing fan; specifically, the coating may be applied to the inner wall of the air dispersing groove 231, or may be applied to the inner wall of the air duct rear shell 24 opposite to the air dispersing groove 231.

The light emitting source 31 is arranged in the ventilation air duct; if the light source is fixed on the inner top surface of the air duct rear shell 24, the light source 31 can conveniently irradiate downwards, and the illumination range can cover the inner wall of the air dispersing groove 231, the inner side wall of the air duct rear shell 24 and the whole air supply fan 21; the light source 31 irradiates the germicidal material layer 32 to excite the germicidal material layer 32 to perform photocatalysis.

In the nano silver-reduced graphene oxide composite material, the size of nano silver particles is between that of atomic clusters and macroscopic particles, and the nano silver-reduced graphene oxide composite material combines the characteristics of nano materials and simple substance silver; the nano silver has very small grain diameter and very large surface area, the number of silver atoms on the surface is very large, the surface atoms have much higher energy than the atoms in the particles, and the high surface energy substance has the adsorption effect on bacteria, so that the bacteria are adsorbed on the surface of the nano silver and lose activity, and the nano silver has a strong function of killing the bacteria.

The reduced graphene oxide composite material can damage bacterial cell membranes, so that substances in cells flow out, and a sterilization effect is achieved; meanwhile, the graphene is a two-dimensional honeycomb monoatomic layer planar structure, the specific surface area of the graphene is large, and the reduced graphene oxide fixes nano-silver particles on a lamellar structure by utilizing abundant polar functional groups of the graphene oxide, so that the nano-silver is stabilized and protected, and the antibacterial performance of the nano-silver is improved.

Research shows that the nano silver-reduced graphene oxide composite material can reduce the release speed of nano silver, so that the nano silver-reduced graphene oxide composite material has lower toxicity compared with nano silver, and can keep good bactericidal performance for a long time. On the other hand, the nano silver-reduced graphene oxide has high catalytic activity under visible light, the activity mechanism is based on the surface plasmon resonance effect of nano silver particles under visible light, and the reduced graphene oxide plays a synergistic role in rapidly conducting plasmon resonance excited electrons.

Fig. 7 is a partial sectional view of the air duct member 23 in fig. 6.

Referring to fig. 7, the nano silver-reduced graphene oxide composite material may be pre-coated in the air dispersing groove 231 on the back side of the air duct member 23, the inner sidewall of the air duct rear case 24, and the outer surface of the air blowing fan 21 by a spray coating method to form a sterilization material layer 32, and then the components are assembled.

In some embodiments, the light source 31 includes a lamp panel and a plurality of LED beads.

The LED lamp beads are attached to the lamp panel, the LED patch lamp beads are large in light emitting angle, scattered in light, wide in irradiation range and relatively close in range, and are very suitable for being used in a ventilation air duct with a relatively narrow space; the lamp panel is attached to the inner top surface of the air duct rear shell 24; can make LED lamp pearl give out light towards ventilation duct's inner wall downwards.

The light emitted by the LED lamp beads is visible light; when the LED lamp bead is started, the nano silver-reduced graphene oxide has strong photocatalytic activity, and can play a role in double-effect sterilization by matching with the sterilization effect of the material. When the LED lamp beads are closed, the air in the ventilation air duct can be sterilized by using the sterilization effect of the nano silver-reduced graphene oxide material.

When the installation, the size of lamp plate can carry out nimble change according to the area size of the space size of ventilation wind channel and the bottom surface in the wind channel backshell 24. An indicator lamp can be arranged on the front cover plate 22 or the lamp panel and used for displaying the working state of the LED lamp beads.

When the LED lamp bead is used, the LED lamp bead and the air supply fan 21 can be synchronously started and stopped, when the air supply fan 21 is started, the air flow is large, and the LED lamp bead is started to perform double-effect sterilization, so that the sterilization is more thorough.

The sterilized air enters the corresponding freezing chamber 11, temperature changing chamber 13 and refrigerating chamber 12 through each air outlet and air supply outlet 242; the air in all the refrigerating rooms in the refrigerator is sterilized, and the overall sterilizing performance of the refrigerator is improved. Because the sterilization component is additionally arranged in the original air duct component 2 of the refrigerator, a sterilization module or a device does not need to be additionally arranged in the refrigerator, the original volume in the refrigerator is not occupied, and the whole sterilization performance of the refrigerator can be improved.

in the refrigerator of the embodiment, on the basis that the refrigerator body 1 of the existing refrigerator is provided with a refrigeration chamber and an air channel assembly 2 for providing a ventilation air channel for the refrigeration chamber, a sterilization material is covered on the inner wall of the existing air channel assembly 2 to form a sterilization material layer 32, and the light-emitting source 31 is additionally arranged in the air channel assembly 2 to excite the sterilization material layer 32 to carry out photocatalysis so as to sterilize air and improve the sterilization effect; no additional sterilization module and no additional fan are needed, so that the internal volume of the refrigerator is not occupied; meanwhile, the sterilization material is sealed in the ventilation air duct and cannot be in direct contact with human bodies or food, so that potential safety hazards can be effectively avoided.
