Description

TECHNICAL FIELD

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

[0002] As a household appliance, a refrigerator is often provided with various functional drawers in the refrigerating chamber to meet the preservation needs of different food materials. In the design of arranging a fruit and vegetable sealed drawer adjacent to a micro-freezing drawer, the sealed drawer needs to maintain a high humidity inside to ensure the freshness of fruits and vegetables, while the micro-freezing drawer needs to operate in a lower temperature range. This functional combination faces the risk of condensation caused by cold quantity transfer in actual application, and there is an urgent need for a solution that can effectively isolate the cold source and maintain a stable environment inside the sealed drawer.

[0003] To solve the above problems, the related technology adjusts the structure of the partition plate, for example, by increasing the thickness of the partition plate or filling the partition plate with thermal insulation materials to slow down the conduction of cold quantity. This kind of structure directly separates the sealed drawer and the micro-freezing drawer by a solid partition plate, intending to block the temperature transfer through the physical properties of the material itself.

[0004] However, the above-mentioned method still has obvious limitations: the thermal conductivity of the partition plate material cannot be completely inhibited, and the cold quantity will continue to be transferred to the side wall of the sealed drawer, causing the surface temperature to be lower than the dew point of the internal air, and thus forming condensation. Condensation accumulates and easily flows to the bottom of the drawer or even outside, affecting food preservation and user experience. In addition, the increase in the thickness of the partition plate also occupies the effective volume of the refrigerating chamber, which is not conducive to space optimization. Therefore, it is necessary to redesign the structure from the structural level and build a drawer arrangement scheme that can dynamically block the transfer of cold quantity and completely avoid the generation of condensation. SUMMARY

[0005] The present application provides a refrigerator drawer structure capable of preventing condensation and a refrigerator to solve the problem that condensation on the surface of the refrigerator drawer cannot be inhibited.

[0006] The first aspect of the present application provides a refrigerator drawer structure capable of preventing condensation, which is arranged in the refrigerating chamber of a refrigerator, and comprises: a sealed drawer, a micro-freezing drawer, and a partition space; the sealed drawer and the micro-freezing drawer are arranged adjacent to each other along the width direction of the refrigerator body; the partition space is arranged between the sealed drawer and the micro-freezing drawer; the front end opening and the rear end opening of the partition space are respectively communicated with the internal space in the refrigerating chamber of the refrigerator to form a front-to-rear through ventilation channel; the ventilation channel is used for exchanging the air in the partition space with the air in the refrigerating chamber of the refrigerator, thereby taking away the cold quantity transferred from the micro-freezing drawer to the partition space.

[0007] By setting the front and rear through ventilation channels, the air in the partition space and the air in the refrigeration chamber are continuously exchanged, thereby taking away the cold quantity transferred to the partition space from the micro-frozen drawer, helping to alleviate the temperature reduction of the side wall of the sealed drawer, and improving the condensation phenomenon caused by temperature difference.

[0008] Optionally, the sealed drawer comprises a first side wall facing the micro-frozen drawer; the micro-frozen drawer comprises a second side wall facing the sealed drawer; the first side wall and the second side wall are oppositely arranged and jointly constitute two opposite lateral boundaries of the partition space in the width direction.

[0009] By oppositely arranging the first side wall of the sealed drawer and the second side wall of the micro-frozen drawer and constituting the lateral boundaries of the partition space, the opposite air space is directly formed by the side walls of the drawer structure itself, which helps to realize air isolation between the two side walls in the limited structural space, thereby reducing direct heat conduction between solids and improving the transfer of cold quantity along the side wall.

[0010] Optionally, the first side wall and the second side wall are both composed of non-thermal insulation materials, and the partition space is internally filled with air to form a dynamic air insulation layer.

[0011] In the present application, the first side wall and the second side wall constituting the two sides of the partition space are both made of non-thermal insulation materials, which cooperate with the internally filled air to form a dynamic air insulation layer between the two side walls, utilize the low thermal conductivity of air to reduce the rate of cold quantity conduction through the solid side wall, and at the same time promote air flow by means of the front and rear ventilation of the partition space, which helps to improve the problem of cold quantity accumulation in the non-thermal insulation material side wall area.

[0012] Optionally, the refrigerator drawer structure further comprises a cover plate and a frame; the cover plate is arranged above the sealed drawer and the micro-frozen drawer and covers the upper opening of the sealed drawer, the micro-frozen drawer and the partition space at the same time; the frame is arranged below the sealed drawer and the micro-frozen drawer and provides a common support structure for the sealed drawer and the micro-frozen drawer; the lower surface of the cover plate constitutes the top boundary of the partition space, and the upper surface of the frame constitutes the bottom boundary of the partition space.

[0013] By setting the common cover plate and frame, the lower surface of the cover plate constitutes the top boundary of the partition space, and the upper surface of the frame constitutes the bottom boundary, so that the partition space has clear structural limits at the top and bottom, which helps to keep the space form of the ventilation channel stable, and at the same time, this structure is convenient for integrated manufacturing and assembly, which can reduce the overall complexity and the number of parts of the structure.

[0014] Optionally, the height of the partition space in the vertical direction is equal to the height of the sealed drawer and the height of the micro-frozen drawer; the depth of the partition space in the front-rear direction is equal to the depth of the sealed drawer and the depth of the micro-frozen drawer.

[0015] In the present application, the partition space is consistent with the adjacent drawer in the height and depth directions, which helps to ensure that the partition space forms a continuous and complete air insulation area along the entire height and depth range of the drawer, thereby expanding the surface area of cold energy dispersion and air exchange, reducing local temperature differences, and improving the uniformity of the anti-condensation effect.

[0016] Optionally, the sealed drawer has a sealing structure; the sealing structure is arranged at the opening edge of the sealed drawer and is used to maintain a high-humidity fresh-keeping environment inside the sealed drawer in the closed state.

[0017] By arranging the sealing structure at the opening edge of the sealed drawer, the high-humidity fresh-keeping environment inside the sealed drawer can be maintained when it is closed, which helps to reduce air exchange between the inside and outside of the drawer, thereby stabilizing the internal humidity and improving the food preservation conditions. In combination with the design of the partition space, the interference of the external cold source on the internal temperature and humidity environment of the drawer can be further reduced.

[0018] Optionally, the micro-frozen drawer is internally provided with an independent temperature control device, which is used to maintain the temperature inside the micro-frozen drawer in a micro-frozen temperature interval that is lower than the refrigeration temperature and higher than the freezing temperature.

[0019] By arranging the independent temperature control device in the micro-frozen drawer, the internal temperature can be maintained in a specific micro-frozen interval that is lower than the refrigeration temperature and higher than the freezing temperature, which helps to provide a suitable low-temperature micro-frozen fresh-keeping environment for food. At the same time, this independent temperature control method reduces the direct thermal influence on the adjacent sealed drawer, and in combination with the partition space structure, the problem of cold energy transmission caused by excessive temperature difference can be improved.

[0020] Optionally, the ventilation channel is configured to utilize the air flow caused by the opening and closing of the refrigerator door and / or the air circulation in the refrigeration compartment formed during the operation of the refrigerator refrigeration system to drive the continuous circulation of air in the partition space.

[0021] The ventilation channel of the present application utilizes the air flow caused by the opening and closing of the refrigerator door and the air circulation in the refrigeration compartment formed during the operation of the refrigeration system to drive the continuous circulation of air in the partition space, which helps to promote the mixing and exchange of cold energy and relatively warm air in the refrigeration compartment, thereby reducing the accumulation of cold energy in the partition space and improving the temperature uniformity of the side wall of the adjacent sealed drawer.

[0022] Optionally, the sealed drawer and the micro-freezing drawer are arranged side by side along the width direction of the refrigerator cabinet; the sealed drawer and the micro-freezing drawer have the same width, the same height, and the same depth.

[0023] In the present application, the sealed drawer and the micro-freezing drawer have the same size in width, height and depth and are arranged side by side along the width direction of the refrigerator cabinet, which helps to realize the regular layout and symmetrical cooperation of the two drawers in structure, so as to facilitate the sharing of the cover plate, the frame body and the formation of the size-matched partition space, provide convenience for manufacturing and assembly, and help to ensure the complete coverage of the air insulation layer on the adjacent sides of the two drawers.

[0024] The second aspect of the present application provides a refrigerator comprising a refrigeration chamber and the anti-condensation refrigerator drawer structure as described in the first aspect, wherein the anti-condensation refrigerator drawer structure is installed in the refrigeration chamber.

[0025] By installing the anti-condensation refrigerator drawer structure in the refrigeration chamber of the refrigerator, the refrigerator can utilize the design of the partition space and the ventilation channel to reduce the heat transfer between adjacent drawers, improve the condensation phenomenon on the side wall of the sealed drawer, and help to improve the rationality of the functional layout of the internal space of the refrigeration chamber and the stability of the food storage environment.

[0026] From the above technical solutions, the present application provides an anti-condensation refrigerator drawer structure and a refrigerator. The refrigerator drawer structure is arranged in the refrigeration chamber of the refrigerator, and comprises a sealed drawer, a micro-freezing drawer and a partition space. The sealed drawer and the micro-freezing drawer are arranged adjacent to each other along the width direction of the refrigerator cabinet. The partition space is arranged between the sealed drawer and the micro-freezing drawer. The front end opening and the rear end opening of the partition space are respectively communicated with the internal space in the refrigeration chamber of the refrigerator to form a front-rear through ventilation channel. The ventilation channel is used for exchanging the air in the partition space with the air in the refrigeration chamber of the refrigerator, so as to take away the cold quantity transferred from the micro-freezing drawer to the partition space, thereby solving the problem that the condensation on the surface of the refrigerator drawer cannot be inhibited.

[0030] The embodiments will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings. In the following description, same numbers refer to same or similar elements throughout the drawings. The embodiments described in the following examples do not represent all the implementations consistent with the present application. They are merely examples of systems and methods consistent with some aspects of the present application.

[0031] It should be noted that the brief description of the terms in the present application is only for the convenience of understanding the following described embodiments, and is not intended to limit the embodiments of the present application. Unless otherwise specified, these terms should be understood according to their ordinary and general meanings.

[0032] The terms "first", "second", "third", and the like in the present specification and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit the specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchanged under appropriate circumstances.

[0033] The terms "include" and "have" and any variations thereof are intended to cover but not exclusive inclusion, for example, a product or device including a series of components does not necessarily limit to all components clearly listed, but can include other components not clearly listed or inherent to these products or devices.

[0034] In the embodiments of the present application, the refrigerator is generally provided with a refrigeration chamber and a freezer.

[0035] Among them, the main role of the refrigeration chamber is to keep fresh. It is usually located in the upper half of the refrigerator, and the design temperature is generally higher than 0 degrees Celsius, usually between 2 degrees Celsius and 8 degrees Celsius. This temperature range is sufficient to slow down the growth rate of bacteria in food, thereby extending the shelf life of food while maintaining the freshness and taste of food. In the refrigeration chamber, various perishable foods such as vegetables, fruits, dairy products, cooked meat and leftovers can be stored.

[0036] Among them, the main function of the freezer is to freeze and store food for a long time. It is usually located in the lower half of the refrigerator, and the design temperature is much lower than 0 degrees Celsius, generally below -18 degrees Celsius. At this extremely low temperature, the water in the food will quickly freeze, effectively preventing the growth of bacteria, so that the food can be stored for a long time without deterioration. In the freezer, meat, fish, ice cream, frozen food and other foods can be stored for a long time.

[0037] As a household appliance, the refrigerator is often equipped with various function drawers in the refrigeration compartment to meet the preservation needs of different food materials. In the design of arranging the fruit and vegetable sealed drawer 1 and the micro-freezing drawer 2 adjacently, due to the significant difference in storage environment, the inside of the sealed drawer 1 needs to maintain a higher humidity to ensure the freshness of fruits and vegetables, while the micro-freezing drawer 2 needs to operate in a lower temperature range. This function combination faces the risk of condensation caused by cold quantity transfer in actual application, and an effective solution is needed to isolate the cold source and maintain a stable environment inside the sealed drawer 1.

[0038] To solve the above problems, the related embodiments adjust the structure of the partition plate, for example, by increasing the thickness of the partition plate or filling the partition plate with thermal insulation materials to slow down the conduction of cold quantity. This structure directly separates the sealed drawer 1 and the micro-freezing drawer 2 by a solid partition plate, intending to block the temperature transfer through the physical properties of the material itself. However, the thermal conductivity of the partition plate material cannot be completely inhibited, and the cold quantity will continue to be transferred to the side wall of the sealed drawer 1, causing the surface temperature to be lower than the dew point of the internal air, and thus forming condensation. After the condensation accumulates, it is easy to flow to the bottom of the drawer or even outside, affecting the preservation of food materials and user experience. In addition, the increase in the thickness of the partition plate also occupies the effective volume of the refrigeration compartment, which is not conducive to space optimization. Therefore, it is necessary to redesign the structure from the structural level and build a drawer arrangement scheme that can dynamically block the transfer of cold quantity and completely avoid the generation of condensation.

[0039] To solve the problem that the condensation on the surface of the refrigerator drawer cannot be inhibited, see Figs. 1-2 The refrigerator drawer structure provided by some embodiments of the present application is arranged in the refrigeration compartment of a refrigerator, and includes a sealed drawer 1, a micro-freezing drawer 2, and a partition space 3. The sealed drawer 1 and the micro-freezing drawer 2 are arranged adjacently along the width direction of the refrigerator body. The partition space 3 is arranged between the sealed drawer 1 and the micro-freezing drawer 2. The front end opening and the rear end opening of the partition space 3 are respectively communicated with the internal space in the refrigeration compartment of the refrigerator, so as to form a front-rear through ventilation channel. The ventilation channel is used for exchanging the air in the partition space 3 with the air in the refrigeration compartment of the refrigerator, so as to take away the cold quantity transferred from the micro-freezing drawer 2 to the partition space 3.

[0040] It should be understood that the sealed drawer 1 is specifically a fruit and vegetable sealed drawer, the internal space of which is relatively closed, and can effectively maintain a high humidity environment to prolong the shelf life of fruit and vegetable food materials; the micro-freezing drawer 2 is used to provide a micro-freezing preservation environment of about 0°C, which is suitable for storing meat, seafood and other food materials that need to be quickly taken and do not need to be completely thawed. The two are arranged adjacent to each other along the width direction of the refrigerator cabinet, that is, when the user faces the refrigerator freezer compartment, the sealed drawer 1 and the micro-freezing drawer 2 are arranged side by side in the left-right direction. The partition space 3 is not a solid, closed cavity, but a gap region naturally formed between the adjacent sealed drawer 1 and micro-freezing drawer 2 to ensure its permeability. The front end opening means that the side of the partition space 3 close to the refrigerator door is in communication with the internal space of the refrigerator freezer compartment, and the rear end opening means that the side of the partition space 3 close to the rear wall of the refrigerator is also in communication with the internal space of the refrigerator freezer compartment, thus forming a smooth and unobstructed ventilation path from the front to the rear of the refrigerator freezer compartment, that is, a front-rear through ventilation channel. When the air in the refrigerator freezer compartment flows due to temperature difference or fan circulation, it will naturally flow through the partition space 3 through the ventilation channel. In this process, the flowing air will fully mix with and exchange heat with the air in the partition space 3. The cold energy transferred from the micro-freezing drawer 2 to the surrounding environment including the partition space 3 due to its low temperature will be carried by the flowing air and diffused to the entire internal space of the refrigerator freezer compartment, thereby avoiding the local accumulation of cold energy between the sealed drawer 1 and the micro-freezing drawer 2, and effectively preventing the condensation of water vapor in the air into dew due to the excessively low local temperature of the outer wall of the sealed drawer 1.

[0041] In some embodiments, the sealed drawer 1 includes a first side wall 11 facing the micro-freezing drawer 2; the micro-freezing drawer 2 includes a second side wall 21 facing the sealed drawer 1; the first side wall 11 and the second side wall 21 are oppositely arranged, and together constitute two opposite lateral boundaries of the partition space 3 in the width direction.

[0042] It should be understood that the "width direction" refers to the horizontal direction perpendicular to the front-rear direction of the refrigerator door, that is, the direction from the left side to the right side of the refrigerator when the user faces the refrigerator door. The first side wall 11 of the sealed drawer 1 and the second side wall 21 of the micro-freezing drawer 2 are parallel to each other and spaced apart in this width direction, and the space between them is the partition space 3. These two side walls are like "left and right side walls" of the partition space 3 in the width direction, which separate the partition space 3 from the storage space inside the sealed drawer 1 and the micro-freezing drawer 2, and at the same time define the lateral range of the channel for air flow. This relative arrangement allows air to flow smoothly between the two side walls in the front-rear direction, thereby achieving the heat exchange and cold energy diffusion functions described above.

[0043] In some embodiments, the first side wall 11 and the second side wall 21 are both made of non-thermal insulation material, and the partition space 3 is filled with air to form a dynamic air insulation layer.

[0044] It should be understood that "non-thermal insulation material" refers to a material with relatively high thermal conductivity and no significant insulation performance, such as plastic such as ABS, PP, etc. Compared with thermal insulation materials such as foamed insulation layer, thermal insulation cotton, etc., non-thermal insulation material is more prone to heat transfer through itself. And "the partition space 3 is filled with air", which means that the space between the first side wall 11 and the second side wall 21 is not vacuum, nor filled with other solid or liquid substances, but naturally filled with air. When there is a temperature difference between the temperature in the sealed drawer 1 and the temperature in the slightly frozen drawer 2, heat will be transferred to the air in the partition space 3 through the first side wall 11 and the second side wall 21 made of non-thermal insulation material, or from the air in the partition space 3 to the first side wall 11 and the second side wall 21. Because air itself has a certain thermal resistance, and natural convection can be generated in the partition space 3 due to temperature difference or a relatively stable air layer can be formed under certain conditions, thus playing a certain dynamic insulation role for the storage space inside the two drawers, that is, forming a "dynamic air insulation layer". This dynamic air insulation layer does not completely prevent heat transfer like fixed thermal insulation materials, but adjusts the rate and mode of heat transfer through the thermal resistance characteristics of air and possible air flow, allowing necessary heat exchange to balance the local temperature and prevent condensation, while reducing excessive heat exchange between the two drawers to a certain extent, avoiding excessive impact on the temperature stability of the respective storage space. The insulation effect will be dynamically adjusted with the change of temperature difference between the two sides and the change of air flow state.

[0045] In some embodiments, the refrigerator drawer structure further comprises: an upper cover 4 and a frame 5; the upper cover 4 is arranged above the sealed drawer 1 and the slightly frozen drawer 2, and covers the upper openings of the sealed drawer 1, the slightly frozen drawer 2 and the partition space 3; the frame 5 is arranged below the sealed drawer 1 and the slightly frozen drawer 2, and provides a common support structure for the sealed drawer 1 and the slightly frozen drawer 2; the lower surface of the upper cover 4 constitutes the top boundary of the partition space 3, and the upper surface of the frame 5 constitutes the bottom boundary of the partition space 3.

[0046] It should be understood that the lower surface of the upper cover 4 constitutes the top boundary of the partition space 3 means that when the upper cover 4 is closed above the sealed drawer 1 and the micro-freezing drawer 2, the lower surface of the upper cover 4 cooperates with the top surface of the sealed drawer 1, the top surface of the micro-freezing drawer 2, and the top end of the first side wall 11 and the second side wall 21 to enclose, thereby forming the closed boundary of the upward direction of the partition space 3, so that the air in the partition space 3 cannot easily escape from the upper opening, ensuring the integrity of the dynamic air insulation layer. The upper surface of the frame 5 constitutes the bottom boundary of the partition space 3 means that the frame 5 serves as the common support base of the sealed drawer 1 and the micro-freezing drawer 2, and the upper surface of the part between the two drawers cooperates with the bottom surface of the sealed drawer 1, the bottom surface of the micro-freezing drawer 2, and the bottom end of the first side wall 11 and the second side wall 21 to constitute the closed boundary of the downward direction of the partition space 3, which is also to ensure the closedness of the partition space 3, so that the air can be effectively limited in the space to play its dynamic insulation role. In short, the lower surface of the upper cover 4 and the upper surface of the frame 5 respectively define and close the partition space 3 from the top and bottom directions, together with the first side wall 11 and the second side wall 21 on both sides, to constitute a relatively independent air cavity, i.e., the partition space 3.

[0047] By setting the common upper cover 4 and the frame 5, the lower surface of the upper cover 4 constitutes the top boundary of the partition space 3, and the upper surface of the frame 5 constitutes the bottom boundary, so that the partition space 3 has clear structural limits at the top and bottom, which helps to keep the space form of the ventilation channel stable, and at the same time, the structure facilitates integrated manufacturing and assembly, and can reduce the overall complexity and the number of parts of the structure.

[0048] In some embodiments, the height of the partition space 3 in the vertical direction is equal to the height of the sealed drawer 1 and the height of the micro-freezing drawer 2; the depth of the partition space 3 in the front-rear direction is equal to the depth of the sealed drawer 1 and the depth of the micro-freezing drawer 2.

[0049] It should be understood that the "equal" referred to here does not mean that the values ​​are simply exactly the same, but rather that the partition space 3, in terms of its overall structural layout and extension range, matches and adapts to the sealed drawer 1 and the micro-freezing drawer 2 in both the vertical height and front-to-back depth directions. Specifically, in the vertical direction, the height of the partition space 3 is designed to extend from the lower surface of the top cover 4 to the upper surface of the frame 5. This height range precisely corresponds to and covers the main body of the sealed drawer 1 and the micro-freezing drawer 2 in the vertical direction, allowing the partition space 3 to effectively separate the sealed drawer 1 and the micro-freezing drawer 2 in the vertical direction, ensuring that the air cavity can surround or correspond to the main storage area of ​​the drawer. Similarly, in the front-to-back direction, the depth of the partition space 3 extends forward from the rear wall of the refrigerator interior or the corresponding fixed structure to be basically flush with or slightly adjusted to accommodate the drawer's pull-out stroke, and its depth is sufficient to cover the entire longitudinal depth of the storage cavity of the sealed drawer 1 and the micro-freezing drawer 2 from back to front. This ensures that when the drawers are fully closed, the partition space 3 can be completely positioned between the two drawers in the front-to-back direction, forming an air insulation barrier that runs through the entire depth of the drawers. This "equal" design principle is to ensure that the partition space 3 can maximize its dynamic insulation effect between the two drawers, ensuring that its space range can effectively cover the area that needs to be separated between the two drawers, avoiding insulation dead corners or airflow short circuits due to size mismatch, thereby optimizing the efficiency of the ventilation channel and the overall insulation effect.

[0050] In some embodiments, the sealed drawer 1 has a sealing structure; the sealing structure is disposed at the opening edge of the sealed drawer 1 to maintain a high humidity preservation environment inside the sealed drawer 1 when it is closed.

[0051] It should be understood that the sealing structure located at the opening edge of the sealed drawer 1 does not simply refer to a single part of the drawer opening, but rather to the perimeter surrounding the entire drawer opening. Specifically, this sealing structure can be an elastic seal continuously or segmented along the upper edge, left edge, right edge, and front edge of the opening of the sealed drawer 1. In the case of a front-opening drawer, the "front edge" can be understood as the side of the drawer panel facing inwards, forming a sealing fit with the refrigerator body or adjacent components. This seal can be made of materials with good elasticity and low-temperature resistance, such as silicone or rubber, forming a sealing ring or sealing strip. When the sealed drawer 1 is fully closed, this sealing structure can tightly fit against the corresponding mating surface of the refrigerator liner, such as the door frame surface of the liner, or the flange or stepped surface corresponding to the opening edge of the sealed drawer 1, thereby forming a complete, perimeter-wide sealing barrier at the opening of the sealed drawer 1. This barrier effectively prevents direct and extensive convection exchange between the high-humidity air inside the drawer and the air outside, thus maintaining the high-humidity preservation environment set inside the sealed drawer 1 and preventing the food stored inside from drying out and spoiling due to excessive moisture loss. At the same time, this perimeter-like sealing design can also reduce the infiltration of lower-humidity air from outside into the sealed drawer 1 to a certain extent, ensuring that the internal humidity can be stably maintained at a high level that is conducive to food preservation.

[0052] In some embodiments, the micro-freezing drawer 2 is provided with an independent temperature control device to maintain the temperature inside the micro-freezing drawer 2 within a micro-freezing temperature range that is lower than the refrigeration temperature and higher than the freezing temperature.

[0053] It should be understood that an independent temperature control device does not mean it is completely independent of the refrigerator's main temperature control system. Rather, it means that, under the coordination of the refrigerator's main temperature control system, it can independently and more precisely adjust and control the temperature inside the micro-freezing drawer 2. Specifically, this independent temperature control device typically includes a temperature sensor, a control module, and heating or cooling actuators such as a small evaporator, a semiconductor cooling chip, or a heating wire. The temperature sensor monitors the actual temperature inside the micro-freezing drawer 2 in real time and transmits the temperature signal to the control module. The control module compares the received actual temperature with a preset micro-freezing temperature range, typically set between -2°C and -6°C, depending on the preservation requirements of different foods. When the temperature inside the drawer is detected to be below the lower limit of this range, the control module will activate the heating element or adjust the cooling capacity to raise the temperature inside the drawer; when the temperature is above the upper limit of the range, it will enhance the cooling effect and lower the internal temperature. Through this closed-loop feedback control mechanism, the temperature inside the micro-freezing drawer 2 is kept stable within the set micro-freezing temperature range, thus providing an ideal preservation environment for the food that can effectively inhibit the growth and reproduction of microorganisms and preserve the cell structure and juices of the food to the greatest extent, thereby achieving long-term fresh storage of the food.

[0054] By setting an independent temperature control device in the micro-freezing drawer 2, the internal temperature can be maintained in a specific micro-freezing range that is lower than the refrigeration temperature and higher than the freezing temperature. This helps to provide a suitable low-temperature micro-freezing preservation environment for food. At the same time, this independent temperature control method reduces the direct thermal impact on the adjacent sealed drawer 1. Combined with the partition space 3 structure, it can improve the problem of cold transfer caused by excessive temperature difference.

[0055] In some embodiments, the ventilation duct is configured to drive continuous air circulation within the partition space 3 by utilizing the air flow generated during the opening and closing of the refrigerator door and / or the air circulation within the refrigerator compartment formed during the operation of the refrigerator refrigeration system.

[0056] It should be understood that the airflow generated during the opening and closing of the refrigerator door specifically refers to the following: When the user opens the refrigerator door, air exchange occurs between the refrigerator compartment and the external environment or other compartments of the refrigerator, such as the freezer compartment. Outside air or air from other compartments may enter the refrigerator compartment, while some air inside the refrigerator compartment may also escape. When the refrigerator door is closed, the air inside the refrigerator compartment is compressed or disturbed. This airflow directly caused by the door's movement disturbs and drives the air within the partition space 3. The air circulation within the refrigerator compartment during the operation of the refrigerator's refrigeration system refers to the fact that when the refrigerator's refrigeration system is working normally, it typically uses devices such as fans to force the air inside the refrigerator compartment to circulate, ensuring temperature uniformity. This continuous and regular airflow passes through or affects the partition space 3, thereby causing the air within the partition space 3 to circulate accordingly. By using one or a combination of these two methods, the ventilation channel can effectively guide and promote the continuous renewal and circulation of air inside the partition space 3, avoid the formation of a local high-humidity environment due to the long-term stagnation of air in the partition space 3, and thus reduce the occurrence of condensation.

[0057] In some embodiments, the sealed drawer 1 and the micro-freezing drawer 2 are arranged side by side along the width of the refrigerator body; the sealed drawer 1 and the micro-freezing drawer 2 have the same width, the same height, and the same depth.

[0058] It should be understood that "same width," "same height," and "same depth" refer to the consistency of the overall dimensions of the two drawers, the sealed drawer 1 and the micro-freezing drawer 2. Specifically, "same width" means that when the two drawers are placed side by side along the width of the refrigerator body, their respective dimensions in the left and right directions of the refrigerator body are equal. This ensures that they can be neatly arranged after installation, avoiding any protrusion or depression on one side, which is beneficial for the fit between the drawers and the refrigerator liner or other components, as well as the overall aesthetics. "Same height" means that the two drawers are the same in the vertical direction, that is, the height from the bottom of the drawer to the edge of the drawer is equal. This ensures that the two drawers are at the same level when installed on the same shelf or drawer slide of the refrigerator, and the top edge of the drawer opening is also aligned, making it convenient for users to access items. It also helps to coordinate spatially with the shelves or bottle holders on the refrigerator door. "Same depth" means that the two drawers have the same dimensions in the front-to-back direction of the refrigerator body, that is, the distance from the front panel to the rear wall of the drawer is equal. This ensures that the two drawers can extend into the refrigerator to the same extent, making full use of the refrigerator's vertical space. Furthermore, when the drawers are closed, the front panels of the two drawers can remain on the same plane, resulting in better fit with the refrigerator door and overall compactness. This complete consistency in three dimensions makes the sealed drawer 1 and the micro-freezing drawer 2 structurally highly interchangeable and uniform, facilitating manufacturing and assembly, and also improving user convenience and visual harmony.

[0059] This application also provides a refrigerator in some embodiments, including a refrigerator compartment and an anti-condensation refrigerator drawer structure as provided in the above embodiments, wherein the anti-condensation refrigerator drawer structure is installed in the refrigerator compartment.

[0060] By installing an anti-condensation refrigerator drawer structure in the refrigerator compartment, the refrigerator can reduce the transfer of cold air between adjacent drawers by utilizing its partition space 3 and ventilation channel design, improve the condensation phenomenon on the side wall of the sealed drawer 1, and help improve the functional layout of the internal space of the refrigerator compartment and the stability of the food storage environment.

[0061] As can be seen from the above technical solutions, the embodiments of this application provide a refrigerator drawer structure and a refrigerator with anti-condensation. The refrigerator drawer structure is set in the refrigerator's cold storage compartment and includes: a sealed drawer 1, a micro-freezing drawer 2, and a partition space 3; the sealed drawer 1 and the micro-freezing drawer 2 are arranged adjacent to each other along the width direction of the refrigerator body; the partition space 3 is set between the sealed drawer 1 and the micro-freezing drawer 2; the front opening and the rear opening of the partition space 3 are respectively connected to the internal space of the refrigerator's cold storage compartment to form a ventilation channel that runs through the front and rear; the ventilation channel is used to exchange the air in the partition space 3 with the air in the refrigerator's cold storage compartment, thereby carrying away the cold air transferred from the micro-freezing drawer 2 to the partition space 3, so as to solve the problem of condensation on the surface of the refrigerator drawer that cannot be suppressed.

[0062] Similar parts between the embodiments provided in this application can be referred to mutually. The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
