Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to a drawer module and a refrigerator. BACKGROUND

[0002] Refrigerators have entered thousands of households and have become good helpers in people's lives. With the continuous improvement of people's living standards and the acceleration of work and life pace, people's functional requirements for refrigerators have also increased, especially higher requirements for the preservation function of refrigerators.

[0003] In the related art, a drawer is arranged in the refrigerator for storing different food materials.

[0004] However, the above-mentioned drawer cannot maintain a high preservation degree, and the storage of fruits, vegetables and other food materials may not meet the long-term preservation. CONTENT OF THE UTILITY MODEL

[0005] The embodiments of the present application provide a drawer module and a refrigerator to solve the technical problem that the drawer cannot maintain a high preservation degree and the storage of fruits, vegetables and other food materials may not meet the long-term preservation.

[0006] In order to achieve the above-mentioned purpose, in a first aspect, the embodiments of the present application provide a drawer module, which comprises:

[0007] A drawer barrel, the drawer barrel is provided with at least one accommodating cavity;

[0008] A drawer body, which is movably arranged in the accommodating cavity;

[0009] An oxygen reduction structure, which comprises an outer shell, a cathode plate and an anode plate; the outer shell is arranged on the side wall of the drawer barrel, and the outer shell is provided with a reaction cavity, and the reaction cavity is at least used for accommodating electrolyte;

[0010] The cathode plate and the anode plate are oppositely arranged, a first surface of the cathode plate is used for contacting the electrolyte in the reaction cavity, and a second surface of the cathode plate faces at least one of the accommodating cavities.

[0011] The drawer module provided by the embodiments of the present application is provided with a reaction cavity in the outer shell, and the reaction cavity is at least used for accommodating electrolyte. The existence of the reaction cavity provides the necessary conditions for electrochemical reaction, so that the cathode plate can effectively perform oxidation-reduction reaction, thereby reducing the oxygen content in the accommodating cavity, and ensuring the efficiency and continuity of the oxygen reduction process.

[0012] The first surface and the second surface of the cathode plate are oppositely arranged. That is, the cathode plate contacts the accommodating cavity and the electrolyte at the same time, the cathode plate can effectively contact the electrolyte and perform oxidation-reduction reaction to consume oxygen, so as to ensure that the oxygen reduction effect directly acts on the accommodating cavity, thereby improving the preservation effect of the food materials.

[0013] Therefore, by setting the above oxygen-reducing structure drawer module, the oxygen-reducing structure can be located outside the containing cavity and only communicate with the containing cavity through the cathode plate, which can effectively reduce the oxygen content in the drawer body without occupying the containing cavity of the drawer body, thereby prolonging the preservation time of fruits, vegetables and other food materials.

[0014] In the above-mentioned drawer module, optionally, the shell is provided with an opening, and the reaction cavity communicates with the opening.

[0015] The cathode plate is located outside the shell, and the cathode plate cover is arranged on the opening, and the first surface of the cathode plate faces the reaction cavity through the opening.

[0016] Through the above-mentioned setting, the electrolyte in the reaction cavity and the cathode plate can effectively exchange substances. The opening ensures that oxygen can enter the reaction cavity and contact with the electrolyte, so as to carry out the oxidation-reduction reaction. Through the above-mentioned setting, the oxygen-reducing structure can effectively reduce the oxygen content in the drawer body through the electrochemical reaction without occupying the containing cavity of the drawer body, thereby prolonging the preservation time of the food materials, and avoiding the space compression problem caused by directly arranging the cathode plate in the containing cavity in the traditional oxygen-removing module

[0017] In the above-mentioned drawer module, optionally, the shell is provided with a support, and the support is arranged on the opening, and the support abuts against the first surface of the cathode plate.

[0018] By arranging the support on the shell, the movement of the cathode plate caused by vibration or other external forces during operation can be prevented, and the continuous and stable electrochemical reaction can be ensured to enhance the stability and reliability of the oxygen-reducing structure. Through the above-mentioned setting, the oxygen-reducing structure can efficiently and stably carry out the electrochemical reaction, thereby reducing the oxygen content in the drawer body and prolonging the preservation time of the food materials. In addition, the space compression problem caused by directly arranging the cathode plate in the containing cavity in the traditional oxygen-removing module can be avoided, and the effective utilization of the containing cavity can be ensured.

[0019] In the above-mentioned drawer module, optionally, the support is provided with a plurality of communication ports, the first end of the communication port communicates with the reaction cavity, and the second end of the communication port faces the first surface of the cathode plate.

[0020] By setting multiple communication openings, the contact area and flow path between the reaction cavity and the cathode plate can be increased, thereby improving the efficiency of oxygen transmission. This design helps to accelerate the consumption process of oxygen and promotes the progress of electrochemical reactions, thereby improving the overall efficiency of electrochemical reactions. The communication structure of the above-mentioned communication opening, the first end of the communication opening communicates with the reaction cavity, ensures that the substances in the reaction cavity can flow smoothly into the communication opening, so that the oxygen in the reaction cavity can quickly reach the cathode plate to participate in the redox reaction, thereby improving the response speed and efficiency of the reaction. The second end of the communication opening faces the first surface of the cathode plate, ensuring that oxygen can directly reach and contact the reaction surface of the cathode plate. The above design can increase the contact area of oxygen and the cathode plate, promote the progress of the redox reaction, and effectively reduce the oxygen content in the containing cavity.

[0021] In the above drawer module, optionally, the shell is provided with a first limiting piece, and the first limiting piece and the outer surface of the shell surround a plug-in slot;

[0022] The cathode plate is inserted into the plug-in slot, and the second surface of the cathode plate abuts against the surface of the first limiting piece facing the shell.

[0023] The first limiting piece and the outer surface of the shell surround the plug-in slot, and the plug-in slot is used to accommodate the cathode plate. The plug-in slot provides a precise installation position for the cathode plate, ensuring correct installation and alignment of the cathode plate and ensuring that the cathode plate can be stably fixed on the shell. On the one hand, it facilitates the installation and disassembly of the cathode plate, and on the other hand, it can ensure the stability of the cathode plate during use. By providing the first limiting piece and the plug-in slot on the shell, the design realizes precise positioning and stable fixation of the cathode plate. Not only can it improve the stability and reliability of the oxygen reduction structure, but also simplify the installation and maintenance process, ensuring the continuous and effective operation of the oxygen reduction structure, thereby prolonging the preservation time of the stored food materials.

[0024] In the above drawer module, optionally, the shell includes a main body and a cover plate, and the cover plate is movably arranged at the top end of the main body.

[0025] The movable design of the cover plate can provide convenient access and operation, allowing users to easily open the cover plate for maintenance, inspection, or replacement of internal components. The above arrangement can improve the maintainability and ease of use of the oxygen reduction structure. In addition, the mobility of the cover plate allows the system to be quickly closed when needed, providing flexible operation options.

[0026] In the above drawer module, optionally, a first sealing piece is arranged between the main body and the cover plate;

[0027] The first sealing piece is annularly arranged at the top end of the main body, and the surface of the first sealing piece away from the main body abuts against the cover plate.

[0028] By setting the first sealing member, the external air or moisture can be effectively prevented from entering the internal space, and the internal gas or liquid can be prevented from leaking to the outside, the sealing performance of the shell can be improved, the stability of the internal environment can be ensured, the low-oxygen environment and stable humidity conditions in the internal can be maintained, and thus the fresh-keeping time of the stored food materials can be prolonged.

[0029] In the drawer module described above, optionally, the main body is provided with a pressing portion surrounding the outer side of the main body.

[0030] The pressing portion is provided with a second sealing member, and the surface of the second sealing member away from the pressing portion abuts against the top end of the partition plate.

[0031] The pressing portion surrounds the outer side of the main body to achieve overall pressing of the main body, which can provide uniform pressure distribution, enhance the stability and sealing effect of the overall structure, and thus improve the efficiency and economy of the welding process equipment. Through this design, the sealing member can be in close contact with the partition plate during installation, ensuring the tightness and effectiveness of the sealing, and further preventing the entry of external air and the leakage of internal gas.

[0032] In the drawer module described above, optionally, the drawer barrel is provided with an intermediate plate located between two adjacent accommodation cavities, and the intermediate plate is provided with a first protection member.

[0033] The first protection member is provided with a plurality of first air vents, and the second surface of the cathode plate faces the accommodation cavity through the first air vents.

[0034] Through the above arrangement, oxygen can enter the accommodation cavity and reach the surface of the cathode plate for consumption, thereby reducing the oxygen content in the accommodation cavity to effectively control the oxygen content in the working environment of the cathode plate, which helps to maintain a low-oxygen environment and prolong the fresh-keeping time of the stored food materials.

[0035] In addition, the arrangement of the first air vents also helps to dissipate heat and prevent local overheating, improving the working efficiency and safety of the cathode plate, and thus facilitating the operation of the oxygen reduction structure.

[0036] In the drawer module described above, optionally, the intermediate plate is reused to form the drawer barrel.

[0037] And / or, the intermediate plate is provided with a mounting groove, and the oxygen reduction structure is arranged in the mounting groove.

[0038] By reusing the intermediate plate partition plate to form the drawer barrel, multifunctionality and structural simplification are achieved. The above arrangement can reduce the number of required independent components, thereby reducing material costs and manufacturing complexity. In addition, the reuse design can improve the overall compactness and space utilization efficiency of the drawer module.

[0039] By designing the intermediate plate partition plate as part of the drawer barrel, the space can be effectively utilized, and the space occupied by the additional intermediate plate partition plate can be reduced, thereby leaving more space for other components.

[0040] By arranging the oxygen reduction structure in the mounting groove, the oxygen reduction structure can be firmly fixed on the intermediate plate. The above arrangement can simplify the assembly process on the one hand, and improve the stability and reliability of the overall structure on the other hand, ensuring that the oxygen reduction structure maintains the correct working position during use, thereby improving the overall performance of the oxygen reduction structure.

[0041] In the above-mentioned drawer module, optionally, the number of oxygen reduction structures is two.

[0042] One of the oxygen reduction structures is arranged corresponding to one of the accommodation cavities, and the other oxygen reduction structure is arranged corresponding to the other accommodation cavity.

[0043] By arranging two oxygen reduction structures, the oxygen content of two different accommodation cavities can be controlled respectively. This design allows independent oxygen management of different accommodation cavities in the same drawer module, thereby meeting the different needs of different food materials for oxygen environment.

[0044] By one-to-one correspondence between the accommodation cavities and the oxygen reduction structures, the oxygen content in each accommodation cavity can be independently adjusted and controlled. In this way, an appropriate oxygen environment can be provided according to the characteristics of the stored food materials (such as different fruits and vegetables), further improving the preservation effect.

[0045] In a second aspect, the application also provides a refrigerator comprising the drawer module according to any one of the preceding aspects.

[0046] The refrigerator provided by the embodiments of the application can provide multiple accommodation cavities with different preservation degrees by arranging the aforementioned drawer module, so as to adaptively preserve different food materials. BRIEF DESCRIPTION OF DRAWINGS

[0067] The specific embodiments of the present application have been shown and described through the above-described drawings, and will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0068] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0069] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0070] In the related art, fruits, vegetables and other food materials have certain requirements for the storage environment. For example, fruits and vegetables have a high water content. If the humidity of the storage environment cannot be met, the water in the fruits and vegetables will gradually be lost, and the oxygen in the air may oxidize the food materials, so that the fruits, vegetables and other food materials cannot be preserved.

[0071] Therefore, some refrigerators are provided with a drawer in the inner container. During the process of frequently opening and closing the refrigerator door by the user, the storage environment in the drawer does not change, and compared with the food materials in the inner container, the storage environment in the drawer is not easy to lose water and has a low oxygen content, so that the freshness of the fruits, vegetables and other food materials can be maintained.

[0072] If long-term preservation is required, it is necessary to maintain a high humidity and a low oxygen content in the drawer. Therefore, an oxygen removal device can be provided in the drawer. The oxygen removal device can replace the oxygen in the drawer to the outside of the drawer through an oxidation-reduction reaction, and discharge the oxygen, so that a low-oxygen environment is obtained in the drawer, which is beneficial to the preservation of fruits and vegetables.

[0073] In the related art, the oxygen removal module includes a cathode and an anode located in an electrolyte cavity. Oxygen undergoes an oxidation-reduction reaction on the cathode to consume oxygen and form negative electrons, and the negative electrons flow to the positive electrode to generate an electric current. The anode undergoes an oxidation-reduction reaction to generate oxygen.

[0074] However, in the above oxygen removal module, the cathode plate is directly arranged in the containing cavity, and the oxygen removal module occupies a large containing cavity. Although the oxygen content in the containing cavity can be reduced through the above-mentioned electrochemical reaction, the space for placing food materials is compressed, which affects the use of the drawer and even the refrigerator.

[0075] Reference Figure 1 In a first aspect, the embodiments of the present application provide a refrigerator 20, which includes an inner container 21.

[0076] The inner container 21 provided by the embodiments of the present application can be used in a freezing compartment to meet the user's demand for moisture preservation of food in the freezing compartment. However, it should be noted that the inner container 21 provided by the embodiments of the present application is not limited to the freezing compartment, but can also be applied to a refrigerating compartment or a variable-temperature compartment.

[0077] The following is described by taking the application of the inner container 21 in the refrigerating compartment as an example.

[0078] In a second aspect, the embodiments of the present application further provide a drawer module 10, which is located in the inner container 21.

[0079] With reference to Figure 2 Specifically, the drawer module 10 includes a drawer barrel 100, a drawer body 200, and an oxygen reduction structure 300. The drawer barrel 100 is installed in the inner container 21, and the drawer barrel 100 is provided with a containing cavity 101.

[0080] It should be noted that the drawer barrel 100 is provided with at least one containing cavity 101. For example, the drawer barrel 100 can be provided with a plate to separate and form multiple containing cavities 101 of different sizes according to the demand, and the number and shape of the containing cavities 101 formed by the drawer barrel 100 are not limited by the embodiments of the present application.

[0081] The drawer body 200 can be located in the containing cavity 101, and the drawer body 200 is movably arranged in the containing cavity 101.

[0082] It can be understood that the movable arrangement means that the drawer body 200 can change the position relative to the drawer barrel 100. For example, when the drawer body 200 is located inside the drawer barrel 100, the drawer body 200 and the drawer barrel 100 jointly form a sealed containing cavity 101, which can be used to store food. For another example, when the user moves the drawer body 200 away from the drawer barrel 100, the containing cavity 101 is opened, and the user can place or take out food.

[0083] Through the above arrangement, the drawer body 200 freely moves in the containing cavity 101, which on the one hand facilitates the user to access the food, and on the other hand the drawer barrel 100 can provide stable support structure for the drawer body 200 to ensure the smooth operation of the drawer body 200.

[0084] It should be noted that the movable manner of the drawer body 200 in the drawer barrel 100 is not within the protection scope of the embodiments of the present application, and will not be described in detail here.

[0085] With reference to Figure 3The oxygen reduction structure 300 includes an outer shell 310, a cathode plate 320, and an anode plate 330. The arrangement of the oxygen reduction structure 300 helps form a low-oxygen environment in the drawer body 200, which is conducive to prolonging the preservation time of fruits, vegetables, and other food materials.

[0086] Specifically, the outer shell 310 is arranged on the sidewall of the drawer barrel 100. By integrating the oxygen reduction structure 300 into the sidewall of the drawer barrel 100, the oxygen reduction structure 300 avoids occupying the accommodation cavity 101 of the drawer body 200, which effectively solves the problem of the oxygen removal module occupying the accommodation cavity 101 in the prior art, and ensures the effective use of the accommodation cavity 101.

[0087] The outer shell 310 is provided with a reaction cavity 301, which is at least used to accommodate electrolyte. The presence of the reaction cavity 301 provides the necessary conditions for electrochemical reaction, so that the cathode plate 320 can effectively perform redox reaction, thereby reducing the oxygen content in the accommodation cavity 101, and ensuring the efficiency and continuity of the oxygen reduction process.

[0088] The cathode plate 320 and the anode plate 330 are oppositely arranged, the first surface 321 of the cathode plate 320 is used to contact the electrolyte in the reaction cavity 301, and the second surface 322 of the cathode plate 320 faces at least one accommodation cavity 101.

[0089] Referring to Figure 3 , Figure 4 It can be understood that the first surface 321 and the second surface 322 of the cathode plate 320 are oppositely arranged. That is, the cathode plate 320 simultaneously contacts the accommodation cavity 101 and the electrolyte, and the cathode plate 320 can effectively contact the electrolyte, perform redox reaction, and consume oxygen, so as to ensure that the oxygen reduction effect directly acts on the accommodation cavity 101, thereby improving the preservation effect of the food materials.

[0090] It should be noted that the oxygen reduction structure 300 with the above-mentioned cathode plate 320 can be arranged outside the accommodation cavity 101, so that the oxygen reduction structure 300 only contacts the accommodation cavity 101 through the second surface 322 of the cathode plate 320, without occupying the accommodation cavity 101, thereby avoiding the space compression problem caused by directly arranging the cathode plate 320 in the accommodation cavity 101 in the traditional oxygen removal module.

[0091] Therefore, by arranging the above-mentioned drawer module 10 with the oxygen reduction structure 300, the oxygen reduction structure 300 can be located outside the accommodation cavity 101 and only communicate with the accommodation cavity 101 through the cathode plate 320, so that the oxygen content in the drawer body 200 can be effectively reduced without occupying the accommodation cavity 101 of the drawer body 200, thereby prolonging the preservation time of fruits, vegetables, and other food materials.

[0092] It can be understood that the drawer module 10 described above can not only improve the preservation of fruits, vegetables and other food materials. For example, the drawer module 10 can reduce the oxygen content of the containing cavity 101 through the aforementioned oxygen reduction structure 300, that is, to provide a low-oxygen environment. Under low-oxygen conditions, the oxidation of other food materials such as meat will also slow down, and the possibility of bacterial growth can be reduced to improve the preservation effect.

[0093] Referring to Figure 3 As an optional embodiment, the shell 310 is provided with an opening 302, and the reaction cavity 301 communicates with the opening 302. The reaction cavity 301 communicates with the containing cavity 101 through the opening 302 to form a channel for the containing cavity 101 and the reaction cavity 301.

[0094] The above arrangement enables the electrolyte and the cathode plate 320 to effectively react with oxygen in the drawer body 200, thereby reducing the oxygen content.

[0095] Through the above arrangement, it can be ensured that the chemical reaction in the electrolyte can proceed smoothly, while allowing oxygen to be effectively replaced from the drawer body 200, thereby forming a low-oxygen environment in the drawer body 200, which is beneficial to prolong the preservation time of food materials.

[0096] The cathode plate 320 is located outside the shell 310, and the cathode plate 320 is arranged on the opening 302.

[0097] Through the above arrangement, the electrolyte in the reaction cavity 301 and the cathode plate 320 can effectively exchange substances. The opening 302 ensures that oxygen can enter the reaction cavity 301 and contact with the electrolyte, thereby performing the redox reaction.

[0098] The above design ensures that the cathode plate 320 can directly contact with the electrolyte in the reaction cavity 301, while not occupying the internal space of the reaction cavity 301. The external design of the cathode plate 320 helps to save internal space, so that the reaction cavity 301 can accommodate more electrolyte, and improve the reaction efficiency.

[0099] Referring to Figure 4 The first surface 321 of the cathode plate 320 faces the reaction cavity 301 through the opening 302, which can ensure that the working surface of the cathode plate 320 can directly participate in the electrochemical reaction. Oxygen can be effectively consumed on the cathode plate 320, thereby reducing the oxygen content of the containing cavity 101 and achieving the purpose of oxygen reduction.

[0100] Through the above arrangement, the oxygen reduction structure 300 can effectively reduce the oxygen content in the drawer body 200 through electrochemical reaction without occupying the containing cavity 101 of the drawer body 200, thereby prolonging the preservation time of food materials, while avoiding the space compression problem caused by directly arranging the cathode plate 320 in the containing cavity 101 in the traditional oxygen removal module

[0101] Referring to Figure 3 As an optional implementation, the shell 310 is provided with a support 340, which is arranged at the opening 302 and abuts against the first surface 321 of the cathode plate 320.

[0102] By arranging the support 340 on the shell 310, the movement of the cathode plate 320 due to vibration or other external forces during operation can be prevented, ensuring the continuous and stable performance of the electrochemical reaction, thereby enhancing the stability and reliability of the oxygen reduction structure 300.

[0103] The support 340 is arranged at the opening 302, ensuring that the cathode plate 320 can be accurately positioned above the opening 302. In this way, the first surface 321 of the cathode plate 320 can always maintain contact with the electrolyte in the reaction cavity 301, ensuring the effective performance of the electrochemical reaction.

[0104] By abutting the support 340 against the first surface 321 of the cathode plate 320, the stability of the cathode plate 320 during electrolysis can be ensured, preventing a decrease in electrolysis efficiency due to poor contact. At the same time, this design helps the electrochemical reaction on the cathode plate 320 to be more uniform and effective, improving the oxygen reduction efficiency.

[0105] Through the above arrangement, the oxygen reduction structure 300 can efficiently and stably perform electrochemical reactions, reducing the oxygen content in the drawer body 200, thereby prolonging the preservation time of food materials. In addition, it can also avoid the problem of space compression caused by directly arranging the cathode plate 320 in the containing cavity 101 in the traditional oxygen removal module, ensuring the effective use of the containing cavity 101.

[0106] Referring to Figure 3 As an optional implementation, the support 340 is provided with a plurality of communication openings 341.

[0107] By arranging multiple communication openings 341, the contact area and flow path between the reaction cavity 301 and the cathode plate 320 can be increased, thereby improving the efficiency of oxygen transmission. This design helps to accelerate the consumption process of oxygen and promotes the performance of electrochemical reactions, thereby improving the overall efficiency of electrochemical reactions.

[0108] It should be noted that the number and distribution of communication openings 341 can be adjusted according to actual conditions, which is not described in the present application.

[0109] The first end of the communication opening 341 communicates with the reaction cavity 301, ensuring that the substances in the reaction cavity 301 can flow smoothly into the communication opening 341, so that the oxygen in the reaction cavity 301 can quickly reach the cathode plate 320 to participate in the redox reaction, improving the response speed and efficiency of the reaction.

[0110] The second end of the communication port 341 faces the first surface 321 of the cathode plate 320, ensuring that oxygen can directly reach and contact the reaction surface of the cathode plate 320. The above design can increase the contact area of oxygen with the cathode plate 320, promoting the progress of the redox reaction, thereby effectively reducing the oxygen content in the accommodation cavity 101.

[0173] Referring to Figure 4 As an optional embodiment, a through port 304 is provided between the bottom end of the partition plate 314 and the bottom wall of the reaction chamber 301, and the first chamber 315 and the second chamber 316 are communicated through the through port 304.

[0174] The partition plate 314 realizes the communication between the first chamber 315 and the second chamber 316 through the through port 304 at the bottom. The through port 304 allows liquid or gas to flow between the first chamber 315 and the second chamber 316. The above-mentioned arrangement can provide a flexible material exchange path, so that the two chambers can share or exchange electrolyte or other reactants. In this way, more uniform reaction conditions or more efficient material transmission can be achieved, improving the overall reaction efficiency of the system.

[0178] The drawer body 200 can be moved relative to the drawer barrel 100 in a direction approaching or away from the rear wall, so that the drawer body 200 is moved into or out of the accommodation cavity 101.

[0179] The above movement mode enables the drawer body 200 to be conveniently pulled out or pushed in, facilitating user access and storage of items, and the operation process is relatively simple, which can improve user experience. In addition, such design also helps to protect the items in the drawer body 200, preventing items from falling or being damaged due to improper operation.

[0180] By designing the mobility of the drawer body 200, the user can easily pull out the drawer body 200 to access its contents, or push it in to hide and protect the contents. Such design improves the utilization efficiency and flexibility of the containing cavity 101, enabling the user to adjust the position of the drawer body 200 and the accessibility of the contents as needed.

[0193] By reusing the intermediate plate 110 to form the drawer barrel 100, multifunctionality and structural simplification are achieved. The above arrangement can reduce the number of independent components required on the one hand, thereby reducing material costs and manufacturing complexity. In addition, the reuse design can improve the overall compactness and space utilization efficiency of the drawer module 10.

[0194] By designing the intermediate plate 110 as part of the drawer barrel 100, space can be effectively utilized, and the space occupied by additional intermediate plates 110 can be reduced, thereby leaving more space for other components.

[0195] As an optional embodiment, the number of oxygen reduction structures 300 is two; one of the oxygen reduction structures 300 is arranged corresponding to one of the accommodation cavities 101, and the other oxygen reduction structure 300 is arranged corresponding to the other accommodation cavity 101.

This design allows independent oxygen management of different accommodation cavities 101 in the same drawer module 10, thereby meeting the different oxygen environment needs of different food materials.

[0197] By one-to-one correspondence of the accommodation cavities 101 and the oxygen reduction structures 300, the oxygen content in each accommodation cavity 101 can be independently adjusted and controlled. This can provide a suitable oxygen environment according to the characteristics of the stored food materials (such as different fruits and vegetables), further improving the preservation effect.
