AI Technical Summary
When existing refrigeration equipment adjusts the oxygen content, the fan causes the air to flow violently within the preservation room, which affects the preservation effect of the food.
An electrolysis module is used to transfer oxygen from the oxygen conditioning chamber to the outside. The oxygen content and air pressure are reduced through a fanless design, which promotes the diffusion of air in the chamber and avoids violent flow.
Without using fans, the oxygen content in the fresh food storage room is reduced, and the violent airflow is decreased, thus improving the preservation effect of food.

DETAILED DESCRIPTION
[0035] The utility model will be described in detail below in combination with the embodiment shown in the drawings. However, the embodiment does not limit the utility model, and the changes in mechanism, method or function made by those skilled in the art based on the embodiment are included in the protection scope of the utility model.
[0036] The terms for indicating spatial relative positions used herein, such as "upper", "lower", "left", "right", "front", "back", etc. are used for the purpose of convenience in description to describe the relationship of one feature relative to another feature as shown in the drawings. It can be understood that the terms for indicating spatial relative positions can be intended to include different orientations other than the orientation shown in the drawings, and should not be understood as limiting the claims. In addition, the description word "horizontal" used herein is not completely equivalent to along the direction perpendicular to the direction of gravity, and a certain angle of inclination is allowed.
[0037] As Figure 1 shown, an embodiment of the utility model provides a refrigeration equipment 100, the refrigeration equipment 100 includes box body 10, first chamber 20 and second chamber 30 in box body 10, oxygen adjusting device 40 between first chamber 20 and second chamber 30.
[0038] The refrigeration equipment 100 of the embodiment can be a refrigerator, a refrigerator cabinet, a wine cabinet, a refrigerated cabinet, etc., and the following will be described taking the refrigeration equipment 100 as a refrigerator as an example, and the overall structure of the refrigerator is as shown in Figure 1 .
[0039] To clearly express the position and direction described in the present embodiment, in the present text, up and down are defined in the direction of gravity, that is, the direction of gravity is downward, and the opposite direction is upward. When defining the user's operation of the articles in the refrigeration device 100, the user stands in front of the refrigeration device 100, and the opposite direction is the rear.
[0040] Continuing to combine Figure 2 As shown, the oxygen adjusting device 40 includes an oxygen adjusting cavity 41 formed in the interior thereof, an electrolysis module 42 located in the oxygen adjusting cavity 41, and the first chamber 20 and the second chamber 30 are both communicated with the oxygen adjusting cavity 41. When preserving the foodstuffs, not only the temperature of the foodstuffs can be reduced, but also the oxygen content in the environment where the foodstuffs are located can be adjusted. In the present embodiment, under the action of the oxygen adjusting device 40, the oxygen content in the first chamber 20 and the second chamber 30 can be adjusted to be lower than the oxygen content in the atmosphere, that is, under the action of the oxygen adjusting device 40, a hypoxic environment can be formed in the first chamber 20 and the second chamber 30. The hypoxic environment can inhibit the aerobic respiration of the fruit and vegetable foodstuffs, reduce the consumption of organic matters such as sugar, and also can reduce the anaerobic respiration of the fruit and vegetable foodstuffs to the minimum, so as to avoid that the alcohol and the like produced by the anaerobic respiration affect the quality of the fruit and vegetable foodstuffs.
[0041] The first chamber 20 and the second chamber 30 are both communicated with the oxygen adjusting cavity 41, thus the air in the first chamber 20 and the second chamber 30 can flow into the oxygen adjusting cavity 41. When the oxygen adjusting device 40 works, the electrolysis module 42 transfers the oxygen in the oxygen adjusting cavity 41 to the outside of the oxygen adjusting cavity 41, the oxygen in the oxygen adjusting cavity 41 is reduced, and the air pressure in the oxygen adjusting cavity 41 is also reduced. In this case, the air pressure in the first chamber 20 and the oxygen adjusting cavity 41 is not balanced, and the air pressure in the second chamber 30 and the oxygen adjusting cavity 41 is also not balanced, thus the air with high oxygen content in the first chamber 20 and the second chamber 30 will diffuse into the oxygen adjusting cavity 41 with low oxygen content, so that the oxygen content in the first chamber 20 and the second chamber 30 is reduced.
[0042] It can be seen that in the present embodiment, the oxygen adjusting device 40 does not need to be provided with a fan, under the action of the electrolysis module 42, the oxygen content and the air pressure in the oxygen adjusting cavity 41 are reduced together, thus the air with high oxygen content in the first chamber 20 and the second chamber 30 will diffuse into the oxygen adjusting cavity 41 with low oxygen content, so that the oxygen content in the first chamber 20 and the second chamber 30 is reduced, and the air will not move violently in the first chamber 20 and the second chamber 30, which is beneficial to the preservation of the foodstuffs.
[0043] Continuing to combine Figures 3-6 As shown, the refrigeration device 100 includes a first box body 21 defining the first chamber 20, a second box body 31 defining the second chamber 30, and the oxygen adjusting device 40 includes a shell 43 defining the oxygen adjusting cavity 41.

Similarly, the second abutting surface 321 and the fourth abutting surface 451 can also be arranged to extend obliquely with respect to the upward and downward directions.
[0052] To further avoid air leakage at the joint of the first channel 222 and the third channel 442, a first sealing gasket 432 can be arranged between the first abutting surface 221 and the third abutting surface 441.

The axis of the first cylinder 443 intersects the plane where the third abutting surface 221 is located, so that the self-tapping screw makes the first abutting surface 221 and the third abutting surface 441 tightly contact when fastening the first joint 22 and the third joint 44.
