For those skilled in the art, the specific meaning of the above terms in the present utility model can be understood according to the specific circumstances.

[0031] It should be noted that in the present application, "oxygen-rich chamber" refers to a space with relatively high oxygen concentration, and users can store oxygen-loving food materials in the oxygen-rich chamber; "oxygen-poor chamber" refers to a space with relatively low oxygen concentration, and users can store food materials prone to oxidation in the oxygen-poor chamber.

[0032] In order for those skilled in the art to better understand the technical solutions in the present utility model, the following will combine the drawings in the embodiments of the present utility model Figure 1 -8, the technical solutions in the embodiments of the present utility model are clearly and completely described.

[0033] An embodiment of the present application provides a refrigerator, referring to Figure 1 , comprising a cabinet 10, a door body (not shown in the figure) pivotally connected with the cabinet 10, the cabinet 10 can include an outer shell 11 and a plurality of inner containers 12 arranged in the outer shell 11, the outer shell 11 is located at the outermost side of the whole refrigerator to protect the whole refrigerator. The plurality of inner containers 12 are wrapped by the outer shell 11, and a foaming layer (not shown in the figure) is arranged in the space between the outer shell 11 and the inner container 12 to reduce the heat dissipation of the inner container 12 to the outside. Each inner container 12 can define a storage chamber open to the front, and the storage chamber can be configured as a refrigeration chamber, a freezing chamber, a variable temperature chamber, etc., and the number and function of the specific storage chamber can be configured according to the pre-requisite. The door body is movably arranged in front of the inner container 12 to open and close the storage chamber of the inner container 12.

[0034] The storage chamber includes an oxygen-rich chamber 121 and an oxygen-poor chamber 122, so that different food materials can be classified and stored to obtain better storage effect.

[0035] The refrigerator further comprises an oxygen production module 30 arranged on the top of the cabinet 10, which has the functions of producing oxygen and producing hydrogen or consuming oxygen. The oxygen produced by the oxygen production module 30 is introduced into the oxygen-rich chamber 121, if the oxygen production module 30 produces hydrogen, the hydrogen produced by the oxygen production module 30 is introduced into the oxygen-poor chamber 122, and if the oxygen production module 30 consumes oxygen, the components in the oxygen production module 30 that consume oxygen are arranged in the oxygen-poor chamber 122. The oxygen concentration in the oxygen-rich chamber 121 and the oxygen-poor chamber 122 is adjusted respectively.

[0036] The arrangement of the oxygen production module 30 on the top of the cabinet 10 does not occupy the storage space in the inner container 12, ensures the storage space in the storage chamber of the refrigerator, and does not occupy the heat preservation space of the foaming layer, and does not affect the preservation effect of the refrigerator. Further, the refrigerator has better heat preservation effect and can also ensure better refrigeration and preservation function.

[0037] Referring to Figure 4 and Figure 5 , the oxygen production module 30 comprises a mounting box 31 fixed on the top of the shell 11, an electrolytic box 32 arranged in the mounting box 31, an electrode in the electrolytic box 32, an electrolyte containing cavity, and a product gas gathering cavity (not shown in the figure).

[0038] For the oxygen production module 30, in a more specific implementation structure, the electrode of the oxygen production module 30 comprises a cathode and an anode which are spaced apart (not shown in the figure). In the illustrated embodiment, the electrolytic box 32 is provided with an opening area for the cathode to expose the surface to the outside, and the anode is arranged in the electrolyte containing cavity. Under the condition of power supply, the cathode is used to reduce the oxygen outside the shell through electrochemical reaction, at this time the oxygen in the air is reduced at the cathode position, and the reaction formula is O2+2H2O+4e→4OH － , so as to reduce the oxygen content outside the shell; the OH － generated by the cathode can be oxidized at the anode to generate oxygen, and the reaction formula is 4OH － →O2+2H2O+4e － , the oxygen produced by the anode of the oxygen production module can be discharged to a specific area through the exhaust hole (not marked in the figure) arranged on the electrolytic box.

[0039] In the specific implementation process, the cathode and the anode can be arranged in the form of a plate, wherein the anode plate arranged in the electrolytic box 32 can be further provided with a plurality of through holes to increase the surface area of the anode and allow the electrolyte or bubbles in the electrolyte containing cavity to pass through.

[0040] Referring to Figure 2 and Figure 3The refrigerator in the embodiment further comprises a pipeline arranged between the oxygen production module 30 and the oxygen adjusting chamber, which is used to pass the oxygen adjusting gas produced by the oxygen production module 30 into the oxygen adjusting chamber, or pass the gas in the oxygen adjusting chamber into the oxygen production module 30. The pipeline comprises an oxygen delivery pipe 41 used to deliver oxygen into the oxygen-rich chamber 121, an exhaust pipe 42 used to deliver the gas in the oxygen-poor chamber 122 into the oxygen production module 30, and an air inlet pipe 43 used to balance the air pressure inside the oxygen-poor chamber 122.

[0041] One end of the oxygen delivery pipe 41 is communicated to the product gas collection cavity, and the other end is communicated to the oxygen-rich chamber 121. When the oxygen production module 30 is running, oxygen is generated by the reaction of the anode and the electrolyte in the electrolyte containing cavity. The oxygen enters the product gas collection cavity. When the oxygen in the product gas collection cavity gradually increases, the oxygen will enter the oxygen-rich chamber 121 through the oxygen delivery pipe 41, thereby increasing the oxygen content in the oxygen-rich chamber 121.

[0042] Referring to Figure 4 and Figure 5 , one end of the exhaust pipe 42 and the air inlet pipe 43 is communicated to the inner cavity of the mounting box 31, and the other end is communicated to the oxygen-poor chamber 122. The end of the exhaust pipe 42 connected to the mounting box 31 is arranged on the side of the cathode. The exhaust pipe 42 delivers the gas in the oxygen-poor chamber 122 to the side of the cathode. The cathode reacts with the oxygen in the gas, so that the oxygen content in the chamber between the mounting box 31 and the electrolytic box 32 is small. The air inlet pipe 43 delivers the oxygen-poor gas into the oxygen-poor chamber 122, so as to reduce the oxygen content in the oxygen-poor chamber 122.

[0043] Referring to Figure 5 , Figure 6 and Figure 7 , in order to realize the flow of the air flow between the mounting box 31 and the oxygen-poor chamber 122, a fan 33 is arranged in the mounting box 31. The fan 33 is arranged at the end of the exhaust pipe 42 connected to the mounting box 31. The position where the mounting box 31 is communicated with the exhaust pipe 42 is provided with an air inlet hole. The fan 33 is specifically arranged at the position of the air inlet hole. Under the driving action of the fan 33, the air flow can be efficiently circulated.

[0044] The end of the exhaust pipe 42 communicated with the air inlet hole is provided with an expanded pipe portion 421. The pipe diameter of the expanded pipe portion 421 gradually increases from the end away from the air inlet hole to the end close to the air inlet hole. It is relatively easy to understand that the expanded pipe portion 421 is provided in an inverted horn structure. Similarly, the hole diameter of the air inlet hole corresponds to the pipe diameter of the expanded pipe portion 421. In this way, the pipe diameter of the expanded pipe portion 421 can match the size of the fan blade of the fan 33, so as to fully utilize the driving action of the fan blade, and make the air flow be transmitted efficiently.

[0045] The end of the air outlet pipe 42 connected with the installation box 31 and the end of the air inlet pipe 43 connected with the installation box 31 are arranged on opposite sides of the electrolysis box 32, that is, the ends of the air outlet pipe 42 and the air inlet pipe 43 close to the installation box 31 are separated by the electrolysis box 32. After the cathode consumes the oxygen in the installation box 31, the gas cavity in the installation box 31 is in an oxygen-poor state, so the air inlet pipe 43 can pass the oxygen-poor gas into the oxygen-poor interval room 122.

[0046] With reference to Figure 4 In an embodiment, the refrigerator further comprises a liquid supplementing box 50 arranged in the cabinet 10, a liquid inlet pipe 51 communicated between the liquid supplementing box 50 and the electrolyte containing cavity, and a driving pump 34 connected in the installation box 31. The liquid inlet pipe 51 is connected with the driving pump 34, and a through-flow pipe 35 is communicated between the driving pump 34 and the electrolyte containing cavity. The driving pump 34 is a water pump. When the electrolyte in the electrolyte containing cavity needs to be supplemented, the driving pump 34 is started, and the liquid in the liquid supplementing box 50 enters the liquid inlet pipe 51 and then enters the through-flow pipe 35 to be supplemented into the electrolyte containing cavity, thereby ensuring the normal operation of oxygen production.

[0047] With reference to Figure 8 In order not to occupy the containing space in the cabinet 10, the storage room is provided with a avoiding space on the side close to the door body. The inner container 12 arranged at the avoiding space is provided with an installation groove recessed towards the foaming layer side in the lower direction. The liquid supplementing box 50 is arranged in the installation groove, and the upper end edge of the liquid supplementing box 50 is flush with the inner surface of the inner container 12. The avoiding space can provide containing space for the storage rack on the inner side of the door body, so that the installation position of the liquid supplementing box 50 reasonably utilizes the structure inside the refrigerator.

[0048] It is easy to understand that the shape of the liquid supplementing box 50 is a flat long rectangle, that is, the thickness dimension of the liquid supplementing box 50 is small, the width dimension is matched with the avoiding space, and the length dimension is large. The liquid supplementing box 50 can not only increase the liquid storage space, but also does not occupy too much heat preservation space, and does not affect the refrigeration effect of the refrigerator.

[0049] The liquid supplementing box 50 is provided with a liquid supplementing opening on the upper end. When the liquid (usually water) in the liquid supplementing box 50 is insufficient, the user can supplement the liquid into the liquid supplementing box 50 through the liquid supplementing opening.

[0050] Further, the liquid inlet pipe 51 is connected to the lower end of the liquid supplementing box 50, and the liquid inlet pipe 51 can pass through the foaming layer. The oxygen supply pipe 41, the air outlet pipe 42 and the air inlet pipe 43 are all connected with the lower end of the installation box 31, and are connected to the rear wall of the oxygen adjusting interval room after passing through the foaming layer.

[0051] In an optional embodiment, the liquid supplementing box 50 can also be arranged on one side of the installation box 31 or above the installation box 31. In this way, the water pump does not need to be installed, and the liquid can be supplemented into the liquid supplementing box 50 through other ways.

[0052] In the optional embodiment, a filtering structure can be arranged in the box 10, and the oxygen supply pipe 41 is communicated with the filtering structure. The oxygen gas is first introduced into the filtering structure, and then is delivered into the oxygen-enriched chamber 121 after being filtered, so as to avoid the electrolyte from polluting the food in the oxygen-enriched chamber 121.

[0053] In addition, in the specific design process, the mounting box 31 comprises a box body 36 and a box cover 37, and the electrolysis box 32 is arranged in the inner cavity of the box body 36. Meanwhile, the mounting box 31 has a first part and a second part which are integrally connected, and the width size of the first part is greater than that of the second part. Therefore, the mounting box 31 has sufficient cavity at the position of the first part to install the fan 33 and the driving pump 34 structure.

[0054] The above detailed description of the embodiments shown in the drawings explains the structure, features and effect of the present application. The above description is only the preferred embodiment of the present application, but the present application is not limited by the drawings. Any change or modification made according to the concept of the present application, or any equivalent embodiment, as long as it does not exceed the spirit of the specification and drawings, should be within the protection scope of the present application.
