The removable installation of the partition plate 160 within the housing 100 facilitates both disassembly and cleaning, as well as adjustment of the size of the first and second spaces 180, 190, thereby facilitating adjustment of the operating space of the sterilization device 400 or the gas regulating block 200 and improving their treatment efficiency. In some examples, the partition plate 160 divides the interior space of the housing 100 into upper and lower layers, namely the first space 180 and the second space 190.

[0052] The diverter device 500 is used to guide the airflow to different positions. The diverter device 500 is set in the shell 100 to guide the gas in the refrigerator's refrigerator compartment into the first space 180 and the second space 190. In some examples, the diverter device 500 is set vertically and close to the side wall of the shell 100.

[0053] The sterilization device 400 is disposed in the shell 100. In some examples, the sterilization device 400 is disposed in the first space 180 of the shell 100 to sterilize the gas entering the first space 180 to kill bacteria in the air and extend the shelf life of food. The sterilized gas flows back to the refrigerator compartment.

[0054] The gas regulating block 200 is arranged in the shell 100. The gas regulating block 200 is provided with a gas regulating substance for absorbing or reacting with gases in the refrigerator's refrigerator compartment that are not conducive to the preservation of fresh fruits and vegetables, such as oxygen and ethylene.

[0072] Continue to refer Figure 3 As shown, in some examples, the gas regulating device of the present application further includes a gas concentration sensor 700. The gas concentration sensor 700 is disposed on the housing 100 and is located in the gas in the refrigerator's refrigeration compartment, and is used to detect the concentration of gases such as oxygen and ethylene in the gas in the refrigerator's refrigeration compartment.

One end of the diverter block 520 is connected to the bottom plate 530, and the other end is opposite the air inlet 550, thereby connecting the air inlet 550 with the first air duct 510 and the second air duct 540. After the airflow from the refrigerator compartment exits the air inlet 550, it is separated by the diverter block 520 and enters the first air duct 510 and the second air duct 540 respectively, and is then guided into the first space 180 and the second space 190 of the housing 100 for processing. The method of disposing the diverter block 520 in the cavity of the bottom plate 530 is simple and facilitates the processing of the bottom plate 530 to form the first air duct 510 and the second air duct 540.

[0086] Figure 9 This is another structural schematic diagram of the gas regulating device provided in one embodiment of the present application after the diverter device 500 and the fan 600 are assembled.

The fan 600 delivers the gas in the refrigerator's refrigerator compartment to the air inlet 550, and discharges the processed gas from the first space 180 and the second space 190 of the shell 100, thereby promoting the flow of gas in the refrigerator's refrigerator compartment between the shell 100 and the refrigerator's refrigerator compartment, and improving the gas processing efficiency; at the same time, the fan 600 is used to guide the airflow, which is convenient, efficient and low-noise.

[0088] Figure 10 Schematic diagram of the structure of the diversion device 500 of the gas regulating device provided in one embodiment of the present application.

[0089] refer to Figure 10As shown, in some examples, the bottom plate 530 includes a first bottom plate 531 and a second bottom plate 532, the second bottom plate 532 is fixedly connected to the side of the first bottom plate 531, the thickness of the first bottom plate 531 is greater than the thickness of the second bottom plate 532, and the first bottom plate 531 and the second bottom plate 532 are staggered, that is, the first bottom plate 531 and the second bottom plate 532 are not located on the same plane, the air inlet 550 is provided on the side where the first bottom plate 531 and the second bottom plate 532 are connected, and the first air duct 510 and the second air duct 540 are located at the same side. On the first bottom plate 531, the first air duct 510 and the second air duct 540 are arranged up and down, corresponding to the first space 180 and the second space 190 in the shell 100 respectively, ensuring that the gas in the refrigerator compartment can enter the first space 180 or the second space 190 through the first air duct 510 or the second air duct 540. The fan 600 is fixedly installed on the second bottom plate 532, and the air outlet of the fan 600 is connected to the air inlet 550, ensuring that the fan 600 sends the gas in the refrigerator compartment into the air inlet 550.

[0090] Figure 11 This is a schematic diagram of a gas regulation control method provided in one embodiment of the present application.

[0091] On the other hand, reference Figure 11 As shown, the present application also provides a gas regulation control method, which is applied to the refrigerator compartment, using the above-mentioned gas regulation device, including:

[0092] The gas concentration sensor 700 detects the concentration of the target gas in the refrigerator's refrigeration compartment. When the concentrations of oxygen and ethylene gas in the refrigerator's refrigeration compartment reach a set value A1, the system automatically turns on the fan 600 and the sterilization device 400. The fan 600 and the sterilization device 400 then continue to operate to regulate and sterilize the gas in the refrigerator's refrigeration compartment within the housing 100. The fan 600 and the sterilization device 400 operate for a minimum of T1 to avoid frequent starts and stops of the fan 600 and the sterilization device 400 due to misjudgments by the gas concentration sensor 700.

[0093] If the gas concentration sensor 700 detects that the concentration of the target gas in the refrigerator compartment drops to the set value B1, the system stops the fan 600 and the sterilization device 400;

[0094] If the fan 600 and the sterilization device 400 continue to operate for time T2 and the concentration of the target gas does not decrease, it means that the gas regulating block 200 has failed and needs to be replaced. The control panel 300 prompts the user to replace the gas regulating block 200.

[0095] It is understandable that the set values ​​A1, B1 and the running times T1, T2 can be set through the control panel according to needs, and will not be repeated here.

[0096] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on the several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.
