Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, and 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 may not meet the long-term preservation of fruits, vegetables and other food materials. CONTENT OF THE UTILITY MODEL

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

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

[0007] a drawer barrel, the drawer barrel being provided with a containing cavity;

[0008] a drawer body, the drawer body being movably arranged in the containing cavity;

[0009] a deoxygenation structure, comprising an outer shell, a cathode plate and an anode plate;

[0010] the outer shell is arranged in the drawer barrel, and the outer shell is used at least for accommodating electrolyte; the cathode plate and the anode plate are both in contact with the electrolyte;

[0011] the cathode plate and the anode plate are arranged in parallel and opposite directions along the horizontal direction; a first surface of the cathode plate faces the anode plate, and a second surface of the cathode plate faces the containing cavity.

[0012] The drawer module provided by the embodiments of the present application ensures that the cathode plate and the anode plate are in contact with the electrolyte to participate in the electrochemical reaction. The electrolyte allows ions to move between the cathode and the anode, thereby promoting the progress of the oxidation-reduction reaction.

[0013] By arranging the cathode plate and the anode plate in parallel and opposite directions horizontally, that is, the distance between the cathode plate and the anode plate is uniform, the effective reaction area between the cathode plate and the anode plate can be increased to a large extent, and the efficiency of the electrochemical reaction can be improved. In addition, the above arrangement can ensure uniform distribution of current density, that is, electric field, reduce uneven corrosion in the electrolysis process, improve electrolysis efficiency and product quality, optimize ion transport path, and thus improve oxygen reduction efficiency.

[0014] The oxygen reduction structure with the above-mentioned cathode sheet can be arranged outside the storage space, so that the oxygen reduction structure only contacts the storage space through the second surface of the cathode sheet, does not occupy the storage space, and avoids the space compression problem caused by directly arranging the cathode plate in the storage space in the traditional oxygen removal module.

[0015] Therefore, by arranging the drawer module with the above-mentioned oxygen reduction structure, the oxygen reduction structure can be located outside the storage space and only communicate with the storage space through the cathode sheet. Without occupying the storage space of the drawer body, the oxygen content in the drawer body can be effectively reduced, and the preservation time of fruits, vegetables and other food materials can be prolonged.

[0016] In the above-mentioned drawer module, optionally, the shell is provided with a reaction cavity, and the reaction cavity is at least used for accommodating the electrolyte.

[0017] The reaction cavity comprises a first chamber and a second chamber in communication, and the shell is provided with a partition plate between the first chamber and the second chamber.

[0018] By dividing the reaction process into two chambers in communication, the reaction conditions such as temperature, pressure or reactant concentration can be more flexibly controlled to help optimize the reaction efficiency and effect. The partition plate can ensure the effective separation of the two chambers while allowing material exchange when needed, which helps to prevent unnecessary mixing or interference, while ensuring that each stage of the reaction can be carried out under appropriate conditions to optimize the control and efficiency of the reaction process.

[0019] In the above-mentioned drawer module, optionally, the anode plate is located in the first chamber, and the cathode plate is located outside the shell.

[0020] The shell is provided with an opening, and the opening communicates with the first chamber, and the cathode plate contacts the electrolyte in the first chamber through the opening.

[0021] The placement of the anode plate in the first chamber ensures that it is in sufficient contact with the electrolyte, effectively participating in the electrochemical reaction, which helps to optimize the reaction conditions and improve the efficiency and effectiveness of the anode reaction. The cathode plate is in contact with the electrolyte in the first chamber through the opening. This ensures that the cathode plate can effectively participate in the reaction process, thereby achieving the oxygen reduction function of the oxygen reduction structure, which can optimize the function of the cathode plate and allow it to work under different environmental conditions, improving the overall efficiency and flexibility of the oxygen reduction structure.

[0022] In the above-mentioned drawer module, optionally, the second chamber is provided with a liquid injection port, which is used at least for introducing the electrolyte.

[0023] The introduction of electrolyte through the liquid injection port ensures that there is always enough electrolyte in the second chamber to maintain the electrochemical reaction, which helps to maintain the operating efficiency and reaction effect of the system, and avoids performance degradation due to insufficient electrolyte. In addition, the presence of the liquid injection port also allows the electrolyte to be replaced or adjusted when needed to adapt to different operating conditions or reaction requirements.

[0024] In the above-mentioned drawer module, optionally, a through port is provided between the bottom end of the partition plate and the bottom wall of the reaction chamber, and the first chamber and the second chamber are connected through the through port.

[0025] Through the connection of the through port, the oxygen reduction structure can flexibly manage and adjust the distribution of substances and reaction conditions in the two chambers. This connectivity allows the electrolyte level in the two chambers to be balanced when needed, ensuring the continuity and stability of the reaction. In addition, this design also helps to achieve efficient heat and mass transfer during the reaction process, improving the performance and reliability of the oxygen reduction structure.

[0026] In the above-mentioned 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.

[0027] The movable design of the cover plate can provide convenient access and operation, so that users can easily open the cover plate for maintenance, inspection or replacement of internal components. The above-mentioned arrangement can improve the maintainability and ease of use of the oxygen reduction structure. In addition, the activity of the cover plate allows the system to be quickly closed when needed, providing flexible operation options.

[0028] In the above-mentioned drawer module, optionally, the cover plate is provided with a through member, the first end of the through member is electrically connected with the cathode plate, and the second end of the through member is electrically connected with the anode plate.

[0029] By providing a through member on the cover plate, the structure of the electrolytic device can be simplified, reducing the use of external connecting wires, thereby reducing the complexity of the overall structure, improving the space utilization and compactness of the device, and facilitating installation and maintenance.

[0030] Optionally, the cathode plate comprises a cathode plate body and a cathode connecting part, the cathode plate body is in contact with the electrolyte in the reaction cavity;

[0031] The cathode connecting part is located at the top end of the cathode plate body, and the cathode connecting part is electrically connected with the first end of the conducting part;

[0032] And / or, the anode plate comprises an anode plate body and an anode connecting part, the anode plate body is in contact with the electrolyte in the reaction cavity;

[0033] The anode connecting part is located at the top end of the anode plate body, and the anode connecting part is electrically connected with the second end of the conducting part.

[0034] Through the above arrangement, the cathode plate body and the anode plate body are in direct contact with the electrolyte, and the cathode plate body and the anode plate body can effectively carry out electrochemical reaction, promote the redox process, to ensure the effective operation of the oxygen reduction structure and the realization of the oxygen reduction function, improve the reaction efficiency and the overall performance of the oxygen reduction structure.

[0035] Optionally, in the drawer module described above, a first sealing member is arranged between the main body and the cover plate;

[0036] The first sealing member is annularly arranged at the top end of the main body, and the surface of the first sealing member away from the main body abuts against the cover plate.

[0037] By arranging the first sealing member, the external air or moisture can be effectively prevented from entering the internal space, and at the same time, the internal gas or liquid can be prevented from leaking to the outside, which can improve the sealing performance of the shell, ensure the stability of the internal environment, and be conducive to maintaining the low-oxygen environment and stable humidity conditions in the internal, thereby helping to prolong the preservation time of the stored food materials.

[0038] Optionally, in the drawer module described above, the cover plate is provided with a liquid injection port, and the liquid injection port is used at least for introducing the electrolyte into the reaction cavity.

[0039] By introducing the electrolyte through the liquid injection port, it is ensured that there is always enough electrolyte in the second chamber to maintain the electrochemical reaction, which is helpful to maintain the operation efficiency and reaction effect of the system, and avoid performance degradation due to insufficient electrolyte. In addition, the presence of the liquid injection port also allows the electrolyte to be replaced or adjusted when needed, to adapt to different operating conditions or reaction requirements.

[0040] Optionally, in the drawer module described above, the cover plate is provided with a liquid level detection member, and the liquid level detection member is used at least for obtaining the liquid level height of the electrolyte in the reaction cavity.

[0041] The liquid level detection piece is arranged on the cover plate to monitor the liquid level in the reaction cavity in real time. This design helps to obtain the liquid level information in time, ensures that the oxygen reduction structure operates under the best liquid level condition, and improves the reliability and safety of the system.

[0042] In the drawer module described above, optionally, the drawer barrel includes a rear wall and two oppositely arranged side walls;

[0043] The drawer body can be moved relative to the drawer barrel in a direction close to or away from the rear wall, so as to move the drawer body into or out of the containing cavity.

[0044] The structure design of the rear wall and the side wall provides stable guidance and support for the drawer body, so that the drawer body remains stable and aligned during movement, which helps to prevent the drawer body from tilting or getting stuck during movement, and improves the smoothness and durability of the drawer body.

[0045] In the drawer module described above, optionally, the oxygen reduction structure is arranged on the side wall, and the side wall is provided with a first protection piece;

[0046] The first protection piece is provided with a plurality of first air vents, and the second surface of the cathode plate faces the containing cavity through the first air vents.

[0047] Through the above arrangement, oxygen can enter the containing cavity and reach the surface of the cathode plate for consumption, thereby reducing the oxygen content in the containing cavity, effectively controlling the oxygen content in the working environment of the cathode plate, helping to maintain a low-oxygen environment, and prolonging the preservation time of the stored food materials.

[0048] In addition, the arrangement of the first air vents also helps to dissipate heat and prevent local overheating, improves the working efficiency and safety of the cathode plate, and thus is conducive to ensuring the operation of the oxygen reduction structure.

[0052] In addition, the arrangement of the second air vents also helps to dissipate heat and prevent local overheating, improves the working efficiency and safety of the cathode plate, and thus is conducive to ensuring the operation of the oxygen reduction structure.

[0076] The specific embodiments of the present application have been shown by the above 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

[0077] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0078] The technical solutions of the present application and how the technical solutions of the present application 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 drawings.

[0079] 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.

[0080] To this end, 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 prone to moisture loss and has a low oxygen content, which can maintain the freshness of fruits, vegetables and other food materials.

[0081] 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 as to obtain a low-oxygen environment in the drawer, which is beneficial to the preservation of fruits and vegetables.

[0082] 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.

[0083] However, in the above oxygen removal module, the height of the cathode plate and the anode plate is different, which may cause the concentration of the electrolyte contacted by the cathode plate and the anode plate to be different, thereby affecting the reaction degree of the electrochemical reaction and affecting the normal use of the oxygen reduction structure and the use of the drawer and even the refrigerator.

[0084] Reference Figure 1 In a first aspect, the embodiments of the present application provide a refrigerator 20, which includes an inner container 21.

[0085] 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 materials 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.

[0086] Hereinafter, the inner container 21 is taken as an example of application in a refrigerating compartment.

[0087] In a second aspect, the embodiments of the present application further provide a drawer module 10, which is located in the inner container 21.

[0088] Reference 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 an accommodation cavity 101.

[0089] It should be noted that the drawer barrel 100 is provided with at least one accommodation cavity 101. Exemplarily, the drawer barrel 100 can be provided with a plate to separate a plurality of accommodation cavities 101 of different sizes according to requirements. The number and shape of the accommodation cavities 101 formed by the drawer barrel 100 are not limited by the embodiments of the present application, and are not limited to the above embodiments.

[0090] The drawer body 200 can be located in the accommodation cavity 101, and the drawer body 200 is movably arranged in the accommodation cavity 101.

[0091] It can be understood that the movably arranged means that the drawer body 200 can change position relative to the drawer barrel 100. Exemplarily, 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 storage space, which can be used for storing food materials. Another exemplary, when the user moves the drawer body 200 away from the drawer barrel 100, the storage space is opened, and the user can place or take out food materials.

[0092] Through the above arrangement, the drawer body 200 freely moves in the accommodation cavity 101, on the one hand, it is convenient for the user to access the food materials. 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.

[0093] It should be noted that the movement 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.

[0094] Referring to Figure 3 The 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 to form a low-oxygen environment in the drawer body 200, which is beneficial to prolong the preservation time of fruits, vegetables and other food materials.

[0095] Specifically, the outer shell 310 is arranged on the side wall of the drawer barrel 100. By integrating the oxygen reduction structure 300 into the side wall of the drawer barrel 100, the oxygen reduction structure 300 avoids occupying the storage space of the drawer body 200, which can effectively solve the problem of occupying the storage space by the oxygen removal module in the prior art, and ensure the effective use of the storage space.

[0096] Referring to Figure 4 The outer shell 310 is provided with a reaction cavity 301, and the reaction cavity 301 is at least used for accommodating electrolyte. The existence of the reaction cavity 301 provides the necessary conditions for the electrochemical reaction, so that the cathode plate 320 can effectively carry out the redox reaction, and then reduce the oxygen content in the storage space, thereby ensuring the efficiency and continuity of the oxygen reduction process.

[0097] The cathode plate 320 and the anode plate 330 are both in contact with the electrolyte, that is, the cathode plate 320 and the anode plate 330 are both immersed in the electrolyte to ensure that they can participate in the electrochemical reaction. The electrolyte allows ions to move between the cathode and the anode, thereby facilitating the progress of the redox reaction.

[0098] The cathode plate 320 and the anode plate 330 are arranged in parallel and opposite directions along the horizontal direction X, that is, the distance between the cathode plate 320 and the anode plate 330 is uniform.

[0099] Through the above arrangement, the effective reaction area between the cathode plate 320 and the anode plate 330 can be increased to a large extent, and the efficiency of the electrochemical reaction can be improved. In addition, the above arrangement can ensure uniform distribution of current density, that is, electric field, reduce uneven corrosion in the electrolysis process, improve electrolysis efficiency and product quality, optimize ion transport path, and thus improve oxygen reduction efficiency.

[0100] The first surface 321 of the cathode plate 320 faces the anode plate 330, and the second surface 322 of the cathode plate 320 faces the accommodation cavity 101.

[0101] 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 respectively arranged in opposite directions. That is, the cathode plate 320 simultaneously contacts the storage space and the electrolyte, and the cathode plate 320 can effectively contact the electrolyte, perform the redox reaction, consume oxygen, and ensure that the oxygen reduction effect directly acts on the storage space, thereby improving the preservation effect of the food materials.

[0102] It should be noted that the oxygen reduction structure 300 with the above cathode plate can be arranged outside the storage space, so that the oxygen reduction structure 300 only contacts the storage space through the second surface 322 of the cathode plate, and does not occupy the storage space, thereby avoiding the problem of space compression caused by directly arranging the cathode plate 320 in the storage space in the traditional oxygen removal module.

[0103] Therefore, by arranging the drawer module 10 with the above oxygen reduction structure 300, the oxygen reduction structure 300 can be located outside the storage space and only communicate with the storage space through the cathode plate, so that the oxygen content in the drawer body 200 can be effectively reduced without occupying the storage space of the drawer body 200, thereby prolonging the preservation time of fruits, vegetables and other food materials.

[0104] Referring to Figure 4 , as an optional embodiment, the shell 310 is provided with a reaction cavity 301, and the reaction cavity 301 is at least used for accommodating the electrolyte.

[0105] The reaction cavity 301 comprises a first chamber 315 and a second chamber 316 in communication, i.e. different chemical reactions or processing procedures can be carried out simultaneously or sequentially in the two chambers without interference, thereby achieving complex or multi-stage reaction processes. By dividing the reaction process into two chambers in communication, the reaction conditions such as temperature, pressure or reactant concentration can be more flexibly controlled to help optimize the reaction efficiency and effect.

[0106] The housing 310 is provided with a partition 314 for physically separating the first chamber 315 and the second chamber 316. The partition 314 is a solid structure, which is generally used to create independent areas in space.

[0107] The partition 314 can provide physical separation of the two chambers while still allowing communication between them. The above separation helps to control or limit the flow of substances when needed, ensuring that each chamber can independently maintain its specific reaction conditions. In this way, the flexibility and control ability of the oxygen reduction structure 300 can be improved, so that different reaction steps can be carried out under optimal conditions. In addition, the partition 314 can also provide structural strength and stability.

[0108] The partition 314 is located between the first chamber 315 and the second chamber 316. The partition 314 plays a dual role of separation and connection.

[0109] The partition 314 can ensure effective separation of the two chambers while allowing exchange of substances when needed, helping to prevent unnecessary mixing or interference while ensuring that each stage of the reaction can be carried out under appropriate conditions to optimize the control and efficiency of the reaction process.

[0110] Referring to Figure 4 As an optional embodiment, the anode plate 330 is located in the first chamber 315, i.e. the anode plate 330 is directly in the environment of the electrolyte, placing the anode plate 330 in the first chamber 315 ensures that it can be in full contact with the electrolyte, thereby effectively participating in the electrochemical reaction, helping to optimize the reaction conditions and improve the efficiency and effect of the anode reaction.

[0111] The cathode plate 320 is located on the outside of the housing 310, which can make the cathode reaction carried out in an environment isolated from the anode, helping to control the ion flow and reaction conditions in the electrolyte and improve the efficiency and safety of electrolysis

[0112] Referring to Figure 3The shell 310 is provided with an opening 302, which is in communication with the first chamber 315. The opening 302 can provide a physical channel between the cathode plate 320 and the electrolyte in the first chamber 315, so as to ensure that the cathode plate 320 can be in contact with the electrolyte through the opening 302, thereby participating in the electrochemical reaction, and helping to allow the necessary reaction process to proceed while maintaining the sealing property.

[0113] The cathode plate 320 is in contact with the electrolyte in the first chamber 315 through the opening 302. This ensures that the cathode plate 320 can effectively participate in the reaction process, thereby realizing the oxygen reduction function of the oxygen reduction structure 300, and can optimize the function of the cathode plate 320, allowing it to work under different environmental conditions, and improving the overall efficiency and flexibility of the oxygen reduction structure 300.

[0114] Referring to Figure 3 As an optional embodiment, the second chamber 316 is provided with a liquid injection port 319, which is used at least for introducing electrolyte. The liquid injection port 319 is used for the injection of liquid. The liquid injection port 319 can be opened and closed by a valve or a cover.

[0115] The liquid injection port 319 can provide a convenient channel for the second chamber 316 to add or replace liquid (such as electrolyte). The above arrangement can simplify the management process of the electrolyte, so that the liquid can be quickly and conveniently supplemented or replaced when needed, thereby ensuring the continuous and effective operation of the oxygen reduction structure 300.

[0116] By introducing electrolyte through the liquid injection port 319, it is ensured that there is always enough electrolyte in the second chamber 316 to maintain the electrochemical reaction, which helps to maintain the operating efficiency and reaction effect of the system, and avoids performance degradation due to insufficient electrolyte. In addition, the presence of the liquid injection port 319 also allows the electrolyte to be replaced or adjusted when needed to adapt to different operating conditions or reaction requirements.

[0117] It should be noted that the shape and size of the liquid injection port 319 can be designed according to the volume of the second chamber 316 and the first chamber 315, and the embodiments of the present application do not limit this.

[0118] Referring to Figure 4 As an optional embodiment, a through port 304 is arranged between the bottom end of the partition plate 314 and the bottom wall of the reaction cavity 301, and the first chamber 315 and the second chamber 316 are in communication through the through port 304.

[0119] The partition 314 enables 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. This arrangement can provide a flexible material exchange path, enabling the two chambers to share or exchange electrolyte or other reactants. In this way, more uniform reaction conditions or more efficient material transport can be achieved, improving the overall reaction efficiency of the system.

[0120] With the communication through the through-port 304, the oxygen reduction structure 300 can flexibly manage and regulate the material distribution and reaction conditions within the two chambers. This connectivity allows the electrolyte level in the two chambers to be balanced when needed, ensuring the continuity and stability of the reaction. In addition, this design also helps to achieve more efficient heat and material transfer during the reaction, improving the performance and reliability of the oxygen reduction structure 300.

[0121] Referring to Figure 3 As an optional implementation, the shell 310 includes a main body 311 and a cover plate 312, which is movably arranged at the top end of the main body 311.

[0122] The main body 311 is the main structural part of the shell 310, which provides a containing space, and the cover plate 312 is used to close or cover the main body 311.

[0123] With the covering of the cover plate 312, it can effectively prevent dust, moisture and other external factors from damaging the internal components and protect the internal components from the external environment.

[0124] The movable design of the cover plate 312 allows users to conveniently access the internal components of the shell 310, facilitating maintenance and repair. At the same time, this design also helps to improve the overall sealing and protection level of the shell 310, as the cover plate 312 can tightly cooperate with the main body 311 in the closed state, preventing external factors from invading, thereby helping to maintain the effective operation of the oxygen reduction structure 300 and prolong the preservation time of the stored food materials.

[0125] The movable design of the cover plate 312 can provide convenient access and operation, allowing users to easily open the cover plate 312 for maintenance, inspection or replacement of internal components. This arrangement can improve the maintainability and ease of use of the oxygen reduction structure 300. In addition, the mobility of the cover plate 312 allows the system to be quickly closed when needed, providing flexible operation options.

[0126] Referring to Figure 5 As an optional implementation, the cover plate 312 is provided with a through-connection member (not shown in the figure), which is used to realize electrical connection between different structures.

The cathode plate body 323 is the main body 311 part of the cathode plate 320, and the cathode connecting part 324 is used for connecting with the external circuit. The above design enables the cathode plate 320 to simultaneously satisfy the dual functions of contacting the electrolyte for electrochemical reaction and connecting with the external circuit for current transmission, thereby improving the practicability and flexibility of the cathode plate 320.

[0131] The cathode plate body 323 contacts the electrolyte in the reaction cavity 301. That is, the cathode plate body 323 directly contacts the electrolyte, and the cathode plate body 323 can effectively perform the electrochemical reaction and promote the redox process, so as to ensure the effective operation of the oxygen reduction structure 300 and the realization of the oxygen reduction function, improve the reaction efficiency, and improve the overall performance of the oxygen reduction structure 300.

[0132] The cathode connecting part 324 is located at the top end of the cathode plate body 323, can be conveniently connected with the conducting piece, can optimize the path of electrical connection, reduce resistance loss, improve the efficiency and reliability of current transmission, and also reduce the space occupied by the connecting part in the reaction cavity 301, thereby improving the space utilization.

[0133] The cathode connecting part 324 is electrically connected with the first end of the conducting piece, so as to ensure that the current can be transmitted to the cathode plate 320, that is, to ensure that the cathode plate 320 can receive necessary current to perform the electrochemical reaction. Through reliable electrical connection, the system can maintain stable current supply, thereby improving the reaction efficiency and the overall performance of the system.

[0136] The anode connecting part 332 is located at the top end of the anode plate body 331, which can conveniently realize the connection with the conducting part, can optimize the path of the electrical connection, reduce the resistance loss, improve the efficiency and reliability of the current transmission, and also reduce the space occupied by the connecting part in the reaction cavity 301, improve the space utilization.

[0137] The anode connecting part 332 is electrically connected with the second end of the conducting part, which ensures that the current can be transmitted to the anode plate 330, that is, the anode plate 330 can receive the necessary current to perform the electrochemical reaction. Through reliable electrical connection, the system can maintain stable current supply, improve the reaction efficiency and the overall performance of the system.

[0138] Referring to Figure 3 , Figure 5 As an optional implementation, the shell 310 is provided with a support 340, the support 340 is arranged at the opening 302, and the support 340 abuts against the first surface 321 of the cathode plate 320.

[0139] 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, the continuous and stable electrochemical reaction is ensured, and the stability and reliability of the oxygen reduction structure 300 are enhanced.

[0140] The support 340 is arranged at the opening 302, which ensures 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.

[0141] By abutting the support 340 with the first surface 321 of the cathode plate 320, the stability of the cathode plate 320 during the electrolysis process 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.

[0142] Through the above arrangement, the oxygen reduction structure 300 can efficiently and stably perform electrochemical reactions, reduce the oxygen content in the drawer body 200, thereby prolonging the preservation time of food materials, and in addition, can avoid the space compression problem caused by directly arranging the cathode plate 320 in the storage space in the traditional oxygen removal module, ensuring the effective use of the storage space.

[0143] Referring to Figure 3 , Figure 5 As an optional embodiment, the support 340 is provided with a plurality of communication openings 341.

[0144] By arranging a plurality of 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 promote the progress of electrochemical reactions, thereby improving the overall efficiency of electrochemical reactions.

[0145] It should be noted that the number and distribution of the communication openings 341 can be adjusted according to actual conditions, which is not described in the present application embodiment.

[0146] 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, thereby improving the response speed and efficiency of the reaction.

[0147] The second end of the communication opening 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 and the cathode plate 320, promote the redox reaction, and thus effectively reduce the oxygen content in the storage space.

[0148] Referring to Figure 3 , Figure 5 As an optional embodiment, the shell 310 is provided with a first limiting piece 350, which can ensure that the cathode plate 320 is installed at the correct position and angle. The first limiting piece 350 provides a clear positioning and fixing position for the cathode plate 320, preventing displacement of the cathode plate 320 during operation, and can improve the stability and overall reliability of the oxygen reduction structure 300.

[0149] The first limiting member 350 and the outer surface of the shell 310 form a plug-in slot 303, which is used to accommodate the cathode plate 320. The plug-in slot 303 provides a precise installation position for the cathode plate 320, ensuring correct installation and alignment of the cathode plate 320, and ensuring that the cathode plate 320 can be firmly fixed on the shell 310. On the one hand, it facilitates the installation and disassembly of the cathode plate 320, and on the other hand, it can ensure the stability of the cathode plate 320 during use.

[0150] The cathode plate 320 is inserted into the plug-in slot 303.

[0151] By inserting the cathode plate 320 into the plug-in slot 303, the cathode plate 320 can be firmly fixed at the designed position. The above installation method can simplify the assembly process and ensure the stability and reliability of the cathode plate 320. In addition, the plug-in installation method can ensure that the cathode plate 320 remains stable during electrolysis, reducing displacement caused by vibration or impact, thereby ensuring electrolysis efficiency and prolonging the service life of the cathode plate 320.

[0152] The second surface 322 of the cathode plate 320 abuts against the surface of the first limiting member 350 facing the shell 310, and the positioning of the cathode plate 320 in the plug-in slot 303 is achieved by contacting the first limiting member 350.

[0153] The abutment of the second surface 322 of the cathode plate 320 and the first limiting member 350 provides additional physical support, preventing the cathode plate 320 from tilting or moving during use, and ensuring that the working surface of the cathode plate 320 can maintain effective contact with the reaction cavity 301, thereby maintaining the efficiency of the electrochemical reaction.

[0154] By providing the first limiting member 350 and the plug-in slot 303 on the shell 310, the design achieves precise positioning and firm fixation of the cathode plate 320. Not only can it improve the stability and reliability of the oxygen reduction structure 300, but also simplify the installation and maintenance process, ensuring the continuous and effective operation of the oxygen reduction structure 300, thereby prolonging the preservation time of the stored food materials.

[0155] Referring to Figure 3 , Figure 5 As an optional embodiment, the shell 310 is provided with a second limiting member 360, which can ensure that the anode plate 330 is installed at the correct position and angle. The second limiting member 360 provides a clear positioning and fixing position for the anode plate 330, preventing displacement of the anode plate 330 during operation, and can improve the stability and overall reliability of the oxygen reduction structure 300.

[0156] The anode plate 330 can be mounted between the second limiting member 360 and the shell 310, and the anode plate 330 can be firmly fixed at a designed position. The mounting manner can simplify the assembly process and ensure the stability and reliability of the anode plate 330, thereby ensuring the electrolysis efficiency and prolonging the service life of the cathode plate 320.

[0157] With reference to Figure 5 As an optional embodiment, the first sealing member 313 is arranged between the main body 311 and the cover plate 312. The first sealing member 313 can ensure the sealing between the two, preventing the leakage of gas or liquid.

[0158] By arranging the first sealing member 313, 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 310 can be improved, the stability of the internal environment can be ensured, the low-oxygen environment and stable humidity conditions in the internal space can be maintained, and the fresh-keeping time of the stored food materials can be prolonged.

[0159] The first sealing member 313 is arranged around the top end of the main body 311. The first sealing member 313 arranged around can provide comprehensive sealing effect, ensure that there is no risk of leakage at the joint between the cover plate 312 and the main body 311, and enhance the sealing performance and protection of the overall structure.

[0160] The surface of the first sealing member 313 away from the main body 311 abuts against the cover plate 312. That is, the outer surface of the first sealing member 313 directly contacts or abuts against the inner surface of the cover plate 312.

[0161] The above arrangement can ensure that the cover plate 312 can tightly press on the first sealing member 313 when the cover plate 312 is closed, thereby enhancing the sealing effect. In this way, the cover plate 312 can apply appropriate pressure on the first sealing member 313 when the cover plate 312 is closed, ensure the tightness and effectiveness of the sealing, and further prevent the entry of external air and the leakage of internal gas.

[0162] Through the above arrangement, the first sealing member 313 can not only improve the sealing performance of the oxygen reduction structure 300, ensure the stability of the internal environment, but also enhance the reliability of the overall structure, thereby helping to maintain the effective operation of the oxygen reduction structure 300 and prolong the fresh-keeping time of the stored food materials.

[0163] With reference to Figure 3 As an optional embodiment, the cover plate 312 is provided with a liquid injection port 319. The liquid injection port 319 is used at least for injecting electrolyte into the reaction cavity 301. The liquid injection port 319 is used for the injection of liquid. The liquid injection port 319 can usually be opened and closed by a valve or a cover.

[0164] The liquid injection port 319 can provide a convenient access for the second chamber 316 to add or replace the liquid (such as electrolyte). The above arrangement can simplify the management process of the electrolyte, so that the liquid can be quickly and conveniently supplemented or replaced when needed, thereby ensuring the continuous and effective operation of the oxygen reduction structure 300.

[0165] By injecting electrolyte through the liquid injection port 319, it ensures that there is always enough electrolyte in the second chamber 316 to maintain the electrochemical reaction, which helps to maintain the operating efficiency and reaction effect of the system, and avoids performance degradation due to insufficient electrolyte. In addition, the presence of the liquid injection port 319 also allows the electrolyte to be replaced or adjusted when needed to adapt to different operating conditions or reaction requirements.

[0166] It should be noted that the shape and size of the liquid injection port 319 can be designed according to the volume of the second chamber 316 and the first chamber 315, and the embodiments of the present application do not limit this.

[0167] As an optional implementation, the cover plate 312 is provided with a liquid level detection member (not shown in the figure), which is used to monitor and measure the liquid level height.

[0168] By providing a liquid level detection member on the cover plate 312, the liquid level in the reaction cavity 301 can be monitored in real time. This design helps to obtain liquid level information in time, ensures that the oxygen reduction structure 300 operates under optimal liquid level conditions, and improves the reliability and safety of the system.

[0169] The liquid level detection member is at least used to obtain the liquid level height of the electrolyte in the reaction cavity 301.

[0170] By obtaining the liquid level height of the electrolyte, the oxygen reduction structure 300 can timely adjust the liquid level to prevent the electrochemical reaction efficiency from being reduced or the equipment from being damaged due to the liquid level being too low.

[0171] As an optional implementation, the drawer barrel 100 includes a rear wall and two oppositely arranged side walls, forming a three-sided enclosed space to provide guidance and support for the drawer body 200.

[0172] The structure design of the rear wall and the side wall provides stable guidance and support for the drawer body 200, so that the drawer body 200 remains stable and aligned during movement, which helps to prevent the drawer body 200 from tilting or jamming during movement, and improves the smoothness and durability of the drawer body 200.

[0173] The drawer body 200 can move relative to the drawer barrel 100 in a direction close to or away from the rear wall, so that the drawer body 200 moves into or out of the accommodation cavity 101.

[0174] The above movement mode enables the drawer body 200 to be conveniently pulled out or pushed in, facilitates user access and storage of articles, and is relatively simple to operate, thereby improving user experience. In addition, this design also helps to protect the articles in the drawer body 200 from falling or being damaged due to improper operation.

[0175] As an optional embodiment, the oxygen reduction structure 300 can be installed at different positions of the drawer body 200.

[0179] It can be understood that the number of first air vents 112 can be selected according to actual conditions, and the embodiments of the present application do not limit this.

[0180] The second surface 322 of the cathode plate 320 faces the accommodation cavity 101 through the first air vents 112. That is, the cathode plate 320 can directly contact the gas in the accommodation cavity 101.

[0181] Through the above arrangement, oxygen can enter the accommodation cavity 101 and reach the surface of the cathode plate 320 for consumption, thereby reducing the oxygen content in the accommodation cavity 101, effectively controlling the oxygen content in the working environment of the cathode plate 320, and helping to maintain a low-oxygen environment and prolong the preservation time of the stored food materials.

[0182] In addition, the arrangement of the first air vents 112 also helps to dissipate heat and prevent local overheating, thereby improving the working efficiency and safety of the cathode plate 320, and further helping to ensure the operation of the oxygen reduction structure 300.

[0183] Referring to Figure 7 As an optional embodiment, the oxygen reduction structure 300 is arranged on the rear wall, and the rear wall is provided with a second protective member 113.

[0184] The second protective member 113 is provided with a plurality of second air vents 114, and the second surface 322 of the cathode plate 320 faces the accommodating cavity 101 through the second air vents 114.

[0185] The second protective member 113 is used to protect other components such as the partition plate 314 from physical damage or environmental effects.

[0186] The second protective member 113 is provided with a plurality of second air vents 114, and the second air vents 114 are used to allow gas to flow in and out of the partition plate 314 to maintain air pressure balance or exchange gas, thereby participating in electrochemical reactions and helping to maintain the effectiveness of the oxygen reduction process.

[0187] It can be understood that the number of second air vents 114 can be selected according to actual conditions, and the embodiments of the present application do not limit this.

[0188] The second surface 322 of the cathode plate 320 faces the accommodating cavity 101 through the second air vents 114. That is, the cathode plate 320 can be in direct contact with the gas in the accommodating cavity 101.

[0189] Through the above arrangement, oxygen can enter the accommodating cavity 101 and reach the surface of the cathode plate 320 for consumption, thereby reducing the oxygen content in the accommodating cavity 101, effectively controlling the oxygen content in the working environment of the cathode plate 320, and helping to maintain a low-oxygen environment and prolong the preservation time of the stored food materials.

[0190] In addition, the arrangement of the second air vents 114 also helps to dissipate heat and prevent local overheating, improve the working efficiency and safety of the cathode plate 320, and thus help to ensure the operation of the oxygen reduction structure 300.

[0191] Referring to Figure 3 As an optional embodiment, the shell 310 is provided with a second sealing member 318, and the surface of the second sealing member 318 away from the shell 310 is connected with the drawer barrel 100.

[0192] The second sealing member 318 is used to prevent gas or liquid leakage. By arranging the second sealing member 318 on the shell 310, the sealing performance between the shell 310 and the partition plate 314 can be improved, the risk of leakage can be reduced, and the reliability of the overall structure can be improved.

[0193] The surface of the second sealing member 318 away from the shell 310 abuts against the top end of the partition plate 314, that is, the side surface of the second sealing member 318 away from the shell 310 directly contacts the top end of the partition plate 314 to form a seal.

[0194] The abutting manner ensures that the sealing member can apply appropriate pressure on the top end of the partition plate 314, thereby enhancing the sealing effect. Through this design, the sealing member can be in close contact with the partition plate 314 during installation, ensuring the tightness and effectiveness of the seal, further preventing the entry of external air and the leakage of internal gas.

[0195] Referring to Figure 5 As an optional embodiment, the main body 311 is provided with a pressing portion 317, which serves to press the main body 311 from the outside to fix or seal the connection of the main body 311 with other components. By providing the pressing portion 317, the main body 311 can be better combined with the partition plate 314 to improve the stability and sealing performance of the overall structure.

[0196] The pressing portion 317 surrounds the outer side of the main body 311 to achieve all-around pressing of the main body 311, which can provide uniform pressure distribution and enhance the stability and sealing effect of the overall structure, thereby improving the efficiency and economy of the welding process equipment.

[0197] The pressing portion 317 is provided with a second sealing member 318, and the surface of the second sealing member 318 away from the pressing portion 317 abuts against the top end of the partition plate 314. The second sealing member 318 is used to prevent gas or liquid leakage. By providing the second sealing member 318 on the pressing portion 317, the sealing performance between the pressing portion 317 and the partition plate 314 can be improved, reducing the risk of leakage and improving the reliability of the overall structure.

[0198] The surface of the second sealing member 318 away from the pressing portion 317 abuts against the top end of the partition plate 314, that is, the side surface of the second sealing member 318 away from the pressing portion 317 directly contacts the top end of the partition plate 314 to form a seal.

[0199] The abutting manner ensures that the sealing member can apply appropriate pressure on the top end of the partition plate 314, thereby enhancing the sealing effect. Through this design, the sealing member can be in close contact with the partition plate 314 during installation, ensuring the tightness and effectiveness of the seal, further preventing the entry of external air and the leakage of internal gas.

[0200] Referring to Figure 2 As an optional embodiment, the drawer barrel 100 is provided with an intermediate plate 110, which is located between two adjacent accommodation cavities 101, and at this time, the oxygen reduction structure 300 is arranged on the side wall. The intermediate plate 110 is provided with the aforementioned first protective member 111, which will not be described here.

[0201] As an optional embodiment, the intermediate plate 110 is provided with a mounting groove 115 for receiving and fixing the main body 311.

[0202] The installation groove 115 can ensure that the main body 311 can be accurately positioned and provide additional physical support and stability, which helps to prevent the main body 311 from shifting or vibrating during use.

[0203] The main body 311 is arranged in the installation groove 115, that is, the bottom or side of the main body 311 is in contact with the inner surface of the installation groove 115.

[0204] By arranging the main body 311 in the installation groove 115, the main body 311 can be firmly fixed on the intermediate plate 110. 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 main body 311 maintains the correct working position during use, thereby improving the overall performance of the oxygen-reducing structure 300.

[0206] That is, the intermediate plate 110 is structurally expanded or reused to form or constitute part of the drawer barrel 100.

[0207] 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.

[0208] 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.

[0209] As an optional embodiment, the number of oxygen-reducing structures 300 is two; one of the oxygen-reducing structures 300 is arranged corresponding to one of the accommodation cavities 101, and the other oxygen-reducing structure 300 is arranged corresponding to the other accommodation cavity 101.

[0210] By arranging two oxygen-reducing structures 300, the oxygen content of two different accommodation cavities 101 can be controlled respectively. This design allows independent oxygen management of different storage spaces in the same drawer module 10, thereby meeting the different oxygen environment needs of different food materials.

[0211] By one-to-one correspondence of the accommodation cavities 101 and the oxygen-reducing 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.
