Description

Technical Field

[0001] This disclosure relates to the field of refrigeration technology, and more particularly to a refrigerator drawer and a refrigerator. Background Technology

[0002] Most refrigerator drawers use a unidirectional airflow method. If cold air is introduced only from the back or top, the airflow distribution inside the drawer will be uneven, which can easily form local "cold zones" and "hot zones". This can cause food to freeze at different speeds, and even lead to problems such as frost formation and dehydration.

[0003] Some drawers in related technologies have air ducts at the bottom to enhance the cooling effect at the bottom. However, the air outlet is directly exposed on the bottom surface of the drawer. When users place food or containers, it is very easy to block the air duct outlet, causing airflow blockage, affecting the cooling performance, and even causing the compressor to start and stop frequently, reducing the reliability of the system. Summary of the Invention

[0067] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0068] In household refrigerators, the quick-freezing function is increasingly attracting user attention as an important means of ensuring food freshness and nutritional content. To achieve rapid and uniform freezing, the freezer drawer of a refrigerator is usually equipped with an independent air circulation system that lowers the food temperature through forced convection of cold air.

[0069] Most refrigerator drawers use a unidirectional airflow method. If cold air is introduced only from the back or top, the airflow distribution inside the drawer will be uneven, which can easily form local "cold zones" and "hot zones". This can cause food to freeze at different speeds, and even lead to problems such as frost formation and dehydration.

[0070] Some drawers in related technologies have air ducts at the bottom to enhance the cooling effect at the bottom. However, the air outlet is directly exposed on the bottom surface of the drawer. When users place food or containers, it is very easy to block the air duct outlet, causing airflow blockage, affecting the cooling performance, and even causing the compressor to start and stop frequently, reducing the reliability of the system.

[0071] In view of this, in one aspect of the present disclosure, a refrigerator drawer is provided that can improve cooling performance.

[0072] Figure 1 These are partial structural schematic diagrams of some embodiments of a refrigerator drawer according to the present disclosure. Figure 2 This is a schematic diagram of the structure of a flow-guiding device according to some embodiments of a refrigerator drawer of this disclosure. Figure 3 This is an exploded view of the structure of some embodiments of the refrigerator drawer according to the present disclosure. Figure 4 These are cross-sectional views of some embodiments of a refrigerator drawer according to this disclosure, with reference to... Figures 1-4 The refrigerator drawer includes an outer shell 1, a receiving cavity 2, an air duct assembly, and a deflector device 6.

[0073] The receiving cavity 2 is disposed inside the housing 1. The air duct assembly is disposed between the housing 1 and the receiving cavity 2 and extends along the first direction X. The air duct assembly includes a first air duct 3 disposed near the bottom of the receiving cavity 2.

[0074] The air intake device 6 is disposed at the bottom of the inner side of the receiving cavity 2 and communicates with the first air duct 3. It has an air intake outlet assembly 60 disposed on the side wall of the receiving cavity 2 perpendicular to the second direction Y. The air intake outlet assembly 60 is configured to allow the cooling air provided by the first air duct 3 to flow towards the receiving cavity 2 along the second direction Y.

[0075] The first direction X is perpendicular to the second direction Y. The first direction X is parallel to the depth direction of the refrigerator drawer. The second direction Y is parallel to the width direction of the refrigerator drawer. The third direction Z is parallel to the height direction of the refrigerator drawer.

[0076] The outer casing 1 includes a side casing 11 and a bottom casing 12. The side casing 11 surrounds the two sides of the receiving cavity 2 along the second direction Y and the side closer to the user along the first direction X. The bottom casing 12 surrounds the bottom of the receiving cavity 2 and has a certain depth for accommodating the first air duct 3.

[0077] The first air inlet 13 of the first air duct 3 is disposed on the bottom shell 12 and located on the side of the bottom shell 12 away from the user along the first direction X. The first air duct 3 receives cooling air through the first air inlet 13. The number of the first air inlets 13 can be adjusted according to actual needs, including but not limited to one or two.

[0078] The refrigerator drawer also includes a top cover 81 and a heat insulation component 82. The top cover 81 is made of glass or plastic, and is located on the top of the drawer body. The heat insulation component 82 is disposed between the receiving cavity 2 and the side shell 11 along the second direction Y. The heat insulation component 82 includes polyurethane foam material, which can achieve heat insulation effect and help improve the energy efficiency of the refrigerator drawer.

[0079] The airflow device 6 is configured to hold stored items. The airflow device 6 is connected to the first air duct 3 and is configured to receive cooling air provided by the first air duct 3. The airflow outlet assembly 60 of the airflow device 6 is located at the bottom of the receiving cavity 2 and opens to both sides of the receiving cavity 2 along the second direction Y. This allows the received cooling air from the first air duct 3 to be discharged to both sides along the second direction Y, thereby preventing food, containers, or other stored items, or ice layers in the refrigerator drawers, from directly blocking the airflow outlet and ensuring that the cooling air from the bottom can be discharged smoothly and reliably.

[0080] In this embodiment, by setting the air diversion device 6, the cooling air provided by the first air duct 3 is discharged to both sides of the bottom of the refrigerator drawer. Compared with the related technology where the air outlet is directly exposed to the bottom surface of the receiving cavity 2, the air diversion outlet assembly 60 guides the cooling air to the sides, which can reduce the risk of airflow blockage caused by food, containers, etc. blocking the air duct outlet. This allows the air diversion outlet assembly 60 to continuously and smoothly provide cooling air into the receiving cavity 2, thereby improving the reliability and stability of the air outlet at the bottom of the refrigerator drawer and enhancing the cooling performance of the refrigerator drawer.

[0081] refer to Figures 1-3 In some embodiments, the drainage device 6 has a drainage cavity, and the number of drainage outlet components 60 is two sets. The two sets of drainage outlet components 60 are respectively arranged on both sides of the drainage cavity along the second direction Y, and a drainage inlet 61 is opened at the bottom of the drainage cavity.

[0082] The first air duct 3 has a first air outlet on the side near the drainage cavity, and the bottom of the receiving cavity 2 has an air guide 21. The first air outlet, the air guide 21 and the drainage air inlet 61 are connected so that the cooling air provided by the first air duct 3 enters the drainage cavity through the first air outlet, the air guide 21 and the drainage air inlet 61.

[0083] The first air duct includes a first cover plate 31 disposed at the top of the air duct, and a first air outlet disposed on the first cover plate 31. The projections of the first air outlet, the air guide 21 and the air inlet 61 on the horizontal plane at least partially overlap, so that the cooling air in the first air duct 3 enters the air inlet cavity through the first air outlet, the air guide 21 and the air inlet 61.

[0084] In this embodiment, the air diversion device 6 includes an air diversion cavity with air diversion outlet components 60 on both sides and an air diversion inlet 61 at the bottom. The air diversion cavity is an independent air chamber relative to the first air duct 3. The air diversion inlet 61 is oriented inwards and does not directly contact the items it carries. Indirect air supply to the bottom of the drawer is achieved through the air diversion cavity, which can further reduce the risk of air duct blockage caused by food, containers or ice covering the bottom air outlet, improve the smoothness of bottom air supply and cooling performance, and reduce the occurrence of frequent compressor start-stop due to blockage, thus ensuring the reliability and stability of refrigeration operation.

[0085] refer to Figure 1 In some embodiments, the bottom edges of the receiving cavity 2 perpendicular to the second direction Y are respectively provided with air guide groove components 22 corresponding to the two sets of air outlet components 60, and each set of air guide groove components 22 is connected to each set of air outlet components 60.

[0086] The air guide duct assembly 22 extends along the second direction Y, and the shape and size of the air guide duct assembly 22 can be adjusted according to actual conditions. The air guide duct assembly 22 is located close to the air outlet assembly 60, which can more efficiently deliver the cooling air discharged from the air outlet assembly 60 into the receiving cavity 2 to contact the stored items, and reduce the obstruction or interference of the edge structure of the receiving cavity 2 on the flow path of the cooling air.

[0087] In this embodiment, by providing an air guide duct assembly 22 that cooperates with the air outlet assembly 60 at the bottom edge of the receiving cavity 2, the cooling air discharged from the air outlet assembly 60 can flow into the receiving cavity 2 more efficiently, reducing the obstruction or interference of the edge structure of the receiving cavity 2 on the cooling air flow path, thereby enhancing the cooling efficiency of the refrigerator drawer, improving the refrigeration performance of the refrigerator drawer, and enabling the refrigerator drawer to achieve a rapid freezing effect.

[0088] refer to Figure 1 and Figure 2 In some embodiments, each group of air guide duct assembly 22 includes a plurality of air guide ducts spaced apart along the first direction X, and each group of air outlet assembly 60 includes a plurality of air outlets spaced apart along the first direction X. The number of air guide ducts and air outlets can be adjusted according to actual conditions.

[0089] In this embodiment, by setting multiple air guide channels and air outlets, the air delivery path of the cooling air can be increased, enabling the refrigerator drawer to cool the stored items quickly and improving the cooling effect. It can also make the cold air evenly distributed at the bottom of the drawer along the first direction X, which can enhance the consistency of the cooling effect in different areas of the refrigerator drawer and improve the preservation quality of food.

[0090] refer to Figure 1 and Figure 2 In some embodiments, mounting grooves 23 are respectively provided on the bottom edges of the receiving cavity 2 perpendicular to the first direction X. The drainage device 6 includes a plug-in portion 62 extending outward relative to the drainage cavity along the first direction X. The drainage device 6 is plugged into the mounting groove 23 through the plug-in portion 62.

[0091] By providing a plug-in portion 62 at the edge of the drainage cavity and a mounting groove 23 that mates with the plug-in portion 62 at the bottom edge of the receiving cavity 2, the plug-in portion 62 can be embedded in the mounting groove 23. The installation method of the plug-in portion 62 mates with the mounting groove 23 can improve the convenience of processing and installation.

[0092] Furthermore, the insertion part 62 is located at the top of the drainage cavity along the third direction Z, which allows the main body of the drainage cavity to be hidden below, reducing the space occupied inside the refrigerator drawer.

[0093] The insertion part 62 is located at the edge of the drainage cavity along the first direction X, which can reduce the interference to the air outlet assembly 60 on both sides along the second direction Y, and allow the drainage device 6 to deliver air smoothly into the receiving cavity 2.

[0094] In this embodiment, by providing a plug-in part 62 at the edge of the drainage cavity along the first direction X and engaging it with the mounting groove 23 of the receiving cavity 2, the ease of disassembly and assembly of the drainage device 6 can be improved, the space occupied inside the refrigerator drawer can be reduced, and the air outlet assembly 60 can avoid the air outlet paths on both sides of the second direction Y, which helps to keep the air outlet assembly 60 running smoothly and reliably.

[0095] Figure 5 This is a schematic diagram of the structure of the second air duct according to some embodiments of the refrigerator drawer of this disclosure, with reference to... Figures 3-5 In some embodiments, the air duct assembly further includes a second air duct 4 and a third air duct 5 respectively disposed on both sides of the receiving cavity 2 along the second direction Y.

[0096] The receiving cavity 2 is recessed inward on both sides along the second direction Y, and respectively abuts against the second air duct 4 and the third air duct 5. The inward recess of the receiving cavity 2 cooperates with the side shell 11 to form an installation space for installing the second air duct 4 and the third air duct 5.

[0097] In this embodiment, by setting a second air duct 4 and a third air duct 5 on both sides of the receiving cavity 2 along the second direction Y, it can cooperate with the first air duct 3 to form a three-sided surrounding air supply structure on both sides and bottom of the refrigerator drawer, so that the refrigerator drawer can achieve multi-directional air supply, avoid uneven airflow distribution in the refrigerator drawer to form local "cold zone" and "hot zone", which is conducive to improving the temperature uniformity of different areas inside the refrigerator drawer, so that the food in the refrigerator drawer has a more consistent freezing speed, reducing problems such as frost and dry loss, and improving cooling efficiency to achieve rapid and uniform cooling.

[0098] refer to Figure 1 , Figure 3 and Figure 4 In some embodiments, the first sidewall 24 of the receiving cavity 2 perpendicular to the first direction X has a second air inlet 25 communicating with the second air duct 4 and a third air inlet 26 communicating with the third air duct 5. The first sidewall 24 also has a return air inlet 27 spaced apart from the second air inlet 25 and the third air inlet 26 along the second direction Y.

[0099] The width of the return air vent 27 along the second direction Y is greater than its height along the third direction Z, and / or the width of the second air inlet 25 and the third air inlet 26 along the second direction Y is less than their height along the third direction Z.

[0100] The second air duct 4 receives cooling air through the second air inlet 25, the third air duct 5 receives cooling air through the third air inlet 26, and the return air inlet 27 is used for cooling air to flow out of the refrigerator drawer, thereby realizing a complete cooling airflow circulation of supply and return air in the refrigerator drawer, so that the cooling air can cover all areas inside the refrigerator drawer, which helps to improve the uniformity of temperature distribution inside the refrigerator drawer.

[0101] The return air vent 27 is designed with a width greater than its height, and can be elliptical, which helps to reduce return air resistance, reduce air intake disturbance and turbulence, and more smoothly remove gas from the refrigerator drawer.

[0102] The second air inlet 25 and the third air inlet 26 are designed in a narrow shape with a width smaller than its height, which can guide the airflow more centrally and directionally, increase the local wind speed, achieve precise air delivery, and enhance the heat exchange efficiency of the target area.

[0103] In this embodiment, making the return air vent 27 wider can reduce the return air resistance at the return air vent 27 and more smoothly bring out the gas in the refrigerator drawer. Making the second air inlet 25 and the third air inlet 26 narrower can increase the local wind speed at the second air inlet 25 and the third air inlet 26, and guide the airflow into the air duct more concentratedly and directionally. This can optimize the airflow circulation efficiency and uniformity of the refrigerator drawer, reduce the temperature difference and energy consumption of the refrigerator drawer, and thus improve the overall preservation effect.

[0104] refer to Figures 3-5 In some embodiments, one or more second diverter plates 41 are provided inside the second air duct 4. The one or more second diverter plates 41 are configured to divide the second air duct 4 into a plurality of second sub-air ducts 40 along a third direction Z. The number of second air inlets 25 is equal to the number of second sub-air ducts 40, and each second air inlet 25 is connected to each second sub-air duct 40; and / or

[0105] One or more third diversion plates 51 are provided inside the third air duct 5. The one or more third diversion plates 51 are configured to divide the third air duct 5 into multiple third sub-air ducts 50 along the third direction Z. The number of third air inlets 26 is equal to the number of second sub-air ducts 40. Each third air inlet 26 is connected to each third sub-air duct 50.

[0106] Multiple second air inlets 25 are spaced apart along the third direction Z. A second diverter plate 41 extends within the second air duct 4 along the first direction X and divides the second air duct 4 into upper and lower second sub-air ducts 40 along the third direction Z. Each second sub-air duct 40 has a smaller cross-sectional area perpendicular to the first direction X, thereby achieving localized airflow contraction, increasing the airflow velocity within the second air duct 4, and improving the overall heat exchange performance and cooling efficiency of the second air duct 4.

[0107] Multiple third air inlets 26 are spaced apart along the third direction Z. A third diverter plate 51 extends within the third air duct 5 along the first direction X and divides the third air duct 5 into upper and lower third sub-air ducts 50 along the third direction Z. Each third sub-air duct 50 has a smaller cross-sectional area perpendicular to the first direction X, thereby achieving localized airflow contraction, increasing the airflow velocity within the third air duct 5, and improving the overall heat exchange performance and cooling efficiency of the third air duct 5.

[0108] In this embodiment, by dividing the second air duct 4 and / or the third air duct 5 into multiple sub-air ducts with smaller cross-sectional areas, it is helpful to achieve local airflow contraction in the second air duct 4 and / or the third air duct 5, thereby increasing the airflow velocity in the second air duct 4 and / or the third air duct 5, which can improve the overall heat exchange performance and cooling efficiency of the second air duct 4 and / or the third air duct 5 and shorten the quick-freezing cycle of the refrigerator drawer.

[0109] refer to Figure 1 , Figure 3 and Figure 5 In some embodiments, the second sidewall 271 of the receiving cavity 2 perpendicular to the second direction Y has a plurality of second air outlets 28 spaced apart along the first direction X. Each second air outlet 28 is connected to a second air duct 4. The second air duct 4 has a second air volume regulating member 42, which is movably disposed relative to the plurality of second air outlets 28. The second air volume regulating member 42 is configured to selectively block the second air outlets 28 to regulate the air volume of the second air duct 4.

[0110] The third sidewall 272 of the receiving cavity 2 perpendicular to the second direction Y has a plurality of third air outlets 29 spaced apart along the first direction X. Each third air outlet 29 is connected to a third air duct 5. The third air duct 5 has a third air volume regulating member, which is movably arranged relative to the plurality of third air outlets 29 and configured to selectively block the third air outlets 29 to regulate the air volume of the third air duct 5.

[0111] The second air volume regulator 42 adjusts the number of second air outlets 28 that are open by selectively blocking different numbers of the multiple second air outlets 28, thereby adjusting the air volume of the second air duct 4 and thus adjusting the amount of cold air entering the receiving cavity 2.

[0112] The second air volume regulating component 42 slides within the second air duct 4. The width of the second air volume regulating component 42 along the first direction X can be adjusted according to the actual situation, such as the width of the second air outlet 28 and the number of the second air outlets 28.

[0113] The width of the second air volume regulating member 42 along the first direction X can be set to be greater than the spacing between the two second air outlets 28 located at both ends, so that when it is necessary to close all the second air outlets 28, the second air volume regulating member 42 can block all the second air outlets 28.

[0114] The third air volume regulator adjusts the number of third air outlets 29 that are open by selectively blocking different numbers of the third air outlets 29, thereby adjusting the air volume of the third air duct 5 and thus adjusting the amount of cold air entering the receiving cavity 2.

[0115] The third air volume adjuster slides within the third air duct 5. The width of the third air volume adjuster along the first direction X can be adjusted according to the actual situation, such as the width of the third air outlet 29 and the number of third air outlets 29.

[0116] The width of the third air volume regulator along the first direction X can be set to be greater than the spacing between the two third air outlets 29 located at both ends, so that when it is necessary to close all the third air outlets 29, the third air volume regulator can block all the third air outlets 29.

[0117] The second airflow regulating component 42 and the third airflow regulating component include a wind-blocking surface perpendicular to the first direction X, which can completely and smoothly block or open the air outlet to achieve a more reliable shielding effect.

[0118] In this embodiment, by setting a second air volume regulator 42 in the second air duct 4 and a third air volume regulator in the third air duct 5, the air volume of the second air duct 4 and the third air duct 5 can be adjusted, thereby allowing the refrigerator drawer to flexibly adjust the air volume for different cooling conditions to meet different load requirements.

[0119] Figure 6 This is a schematic diagram showing the connection relationship of refrigerator drawers according to some embodiments of the present disclosure. Figure 7 This is an exploded view of the structure of a refrigerator drawer according to some other embodiments of the present disclosure, with reference to... Figure 6 and Figure 7 In some embodiments, the refrigerator drawer also includes a temperature detection device 71 and a controller 72.

[0120] Temperature detection device 71 is configured to acquire the temperature inside the refrigerator drawer. Controller 72 is signal-connected to temperature detection device 71, second airflow regulator 42, and third airflow regulator, and is configured to switch the positions of second airflow regulator 42 and third airflow regulator based on the temperature detected by temperature detection device 71, thereby adjusting the number of second air outlets 28 blocked by second airflow regulator 42 and the number of third air outlets 29 blocked by third airflow regulator 42.

[0121] The temperature detection device 71 monitors the temperature changes inside the refrigerator drawer in real time, so that the controller 72 can determine the corresponding cooling demand based on the temperature changes inside the refrigerator drawer, and open or close the corresponding number of second air outlets 28 and third air outlets 29 according to the required cooling amount.

[0122] Furthermore, the refrigerator drawer can also be equipped with a pressure sensor configured to detect the weight of food inside, allowing the controller 72 to adjust the airflow based on this weight. For example, when the drawer is empty or lightly loaded, only one of the second and third air vents 28 and 29 can be opened to reduce airflow and prevent over-cooling. As the weight of food in the drawer increases, more of the second and third air vents 28 and 29 are opened. When a significant weight is detected in the drawer, all of the second and third air vents 28 and 29 can be opened to increase airflow and achieve rapid freezing.

[0123] When a large number of the second air outlet 28 and the third air outlet 29 are open, the refrigerator will have a louder operating noise and will also consume more energy. The controller 72 can also adjust the number of the second air outlet 28 and the third air outlet 29 that are open based on the operating noise and energy efficiency performance.

[0124] In this embodiment, based on the temperature inside the refrigerator drawer monitored by the temperature detection device 71, the number of second air outlets 28 blocked by the second air volume regulator 42 and the number of third air outlets 29 blocked by the third air volume regulator are adjusted, thereby enabling multi-level adaptive control of air volume for different operating conditions, so that the refrigerator drawer can achieve a balance between cooling performance, energy efficiency and operating noise.

[0125] refer to Figure 6 In some embodiments, the controller 72 is further configured to, in response to a temperature rise in the refrigerator drawer exceeding a first preset value within a preset time, prevent the second airflow regulator 42 from blocking the second air outlet 28 and prevent the third airflow regulator from blocking the third air outlet 29.

[0126] The controller 72 is further configured to, in response to the refrigerator drawer temperature being lower than a second preset value, cause the second airflow regulator 42 to block a first preset number of second air outlets 28 and cause the third airflow regulator to block a first preset number of third air outlets 29.

[0127] The number of the second air outlet 28 and the third air outlet 29 is a second preset number, and the first preset number is greater than zero and less than the second preset number. The second preset number can be three, and the first preset number can be two.

[0128] If the temperature rise of the refrigerator drawer exceeds the first preset value within a preset time, the temperature inside the refrigerator drawer will suddenly increase, indicating a thermal disturbance event. In this case, the refrigerator drawer needs to enter the high-speed freeze mode. By adjusting the positions of the second and third airflow regulators 42 and 29, all second and third airflow outlets 28 and 29 will be unobstructed, meaning all outlets will be open to achieve maximum airflow and allow the refrigerator drawer to quickly restore its cooling balance.

[0129] The preset time can be 30 seconds, and the first preset value can be 3 degrees Celsius. The preset time and the first preset value can be adjusted according to the actual situation.

[0130] When the temperature of the refrigerator drawer is lower than the second preset value, the target temperature has been achieved inside the refrigerator drawer. By adjusting the position of the second air volume regulator 42 and the third air volume regulator, only a small number of the second air outlets 28 and the third air outlets 29 are kept open, for example, only one second air outlet 28 and one third air outlet 29 are opened, so that the refrigerator drawer is in energy-saving mode.

[0131] Users can also select different modes through the refrigerator's control panel, such as "quick freeze", "energy saving" or "quiet" mode. The controller 72 can adjust the position of the second air volume regulator 42 and the third air volume regulator according to the mode selected by the user to match different air volumes.

[0132] In this embodiment, the cooling air volume delivered to the refrigerator drawer by the second air duct 4 and the third air duct 5 is adjusted according to different operating conditions of the refrigerator drawer to achieve graded air volume adjustment. This can take into account the cooling performance, energy saving and low noise operation of the refrigerator drawer, and flexibly meet the different cooling needs of users, so that the refrigerator drawer can achieve better cooling performance.

[0133] refer to Figure 7 In some embodiments, the refrigerator drawer further includes an electrical connector 73 disposed on the housing 1 and at least partially exposed relative to the housing 1, for electrical connection with a conductive portion of the drawer support.

[0134] The temperature detection device 71 and the electrical connector 73 can be disposed on the side of the housing 1 closest to the user along the first direction X. The main body of the electrical connector 73 is disposed on the inner wall of the housing 1, with a portion protruding outward relative to the housing 1, so as to electrically connect with the conductive part of the drawer support outside the refrigerator drawer. The electrical connector 73 and the conductive part realize the transmission of electrical energy and signals through the electrical connector, so that the electrical connector 73 supplies power to the controller 72 and the temperature detection device 71 and realizes the transmission of electrical signals.

[0135] The electrical connector 73 can be configured as a spring contact. During the sliding process of the refrigerator drawer, the electrical connector 73 always maintains contact with the conductive part, achieving stable and reliable elastic contact, thereby continuously supplying power to electrical components such as the controller 72 and temperature detection device 71 inside the refrigerator drawer and transmitting electrical signals.

[0136] In this embodiment, by setting an electrical connector 73 inside the refrigerator drawer, compared to the method of welding wires inside the drawer or using an external junction box in some related technologies, the electrical connector 73 does not require welding and wiring, can be used immediately, simplifies the assembly process, and can also avoid problems such as cable breakage and poor contact caused by frequent pushing and pulling of the refrigerator drawer during use. It has extremely high reliability, and the refrigerator drawer can also be easily pulled out for cleaning or replacement, which is convenient for maintenance.

[0137] In another aspect of the present disclosure, a refrigerator is provided, including: a refrigerator drawer as described in any of the above embodiments.

[0138] In this embodiment, a refrigerator with a drawer equipped with a diversion device 6 is used to discharge the cooling air provided by the first air duct 3 to both sides of the bottom of the refrigerator drawer. This can effectively reduce the risk of food, containers or ice covering the bottom air outlet and causing the air duct to be blocked, improve the smoothness of bottom air supply and cooling performance, and further reduce the occurrence of frequent compressor start-stop due to blockage, thus ensuring the reliability of refrigeration operation.

[0139] refer to Figure 7 In some embodiments, the refrigerator further includes drawer slides, drawer supports, and conductive parts. The drawer slides are disposed on the inner wall of the refrigerator and extend along a first direction X. The drawer supports are slidably disposed on the drawer slides and configured to support the refrigerator drawers. The conductive parts are disposed on the drawer supports.

[0140] The refrigerator drawer also includes an electrical connector 73, which is disposed on the outer casing 1 and at least partially exposed relative to the outer casing 1, and is configured to be electrically connected to a conductive part to supply power to electrical components inside the refrigerator drawer and to enable the transmission of electrical signals.

[0141] In this embodiment, by providing an electrical connector 73 inside the refrigerator drawer and maintaining continuous contact with the conductive part provided on the drawer bracket, a reliable electrical connection with temperature can be achieved. This simplifies the assembly process, improves production efficiency, and ensures that the electrical components inside the refrigerator drawer are in a stable and reliable working state.

[0142] refer to Figures 1-7 The following are some examples of refrigerator drawers:

[0143] The refrigerator drawer body is injection molded from low-temperature resistant ABS material, with a compact overall structure and good sealing performance, making it suitable for the low-temperature environment of the refrigerator freezer compartment.

[0144] The refrigerator drawer adopts a three-sided surround air supply structure design. The inner walls on the left and right sides of the drawer are equipped with symmetrically arranged second air ducts 4 and third air ducts 5 to achieve lateral air supply. The second air duct 4 has two second air inlets 25 and the third air duct 5 has two third air outlets 29. Using two air inlets can improve air supply efficiency.

[0145] A second diverter plate 41 is installed inside the second air duct 4, and a third diverter plate 51 is installed inside the third air duct 5. By dividing the upper and lower air paths, the air duct space can be reduced, and the airflow velocity can be increased through local flow contraction, thereby improving the overall heat exchange performance and cooling efficiency of the air-cooled system.

[0146] Cold air can enter the second air duct 4 and the third air duct 5 through the second air inlet 25 and the third air inlet 26 respectively. After being split inside the air duct, it finally enters the drawer through the three second air outlets 28 and the three third air outlets 29.

[0147] The bottom of the refrigerator drawer is equipped with a closed-loop air duct consisting of a first air duct 3 and a diversion device 6, which is sealed by a first cover plate 31 to form an independent air chamber. Cold air is introduced from the first air inlet 13 of the first air duct 3, enters the diversion device 6, and is then delivered into the drawer through the evenly distributed air outlet components 60 on the side wall of the diversion device 6 and the air guide groove components 22 in the receiving cavity 2. This achieves indirect air supply from the bottom, effectively preventing food, containers, or ice from directly covering the air outlet, preventing air duct blockage, and ensuring smooth air supply.

[0148] After entering the drawer from the left, right and bottom sides, the cold air finally flows out from the return air vent 27 on the back of the drawer, forming a complete air supply-return circulation path. This creates a three-dimensional circulating airflow inside the drawer, allowing the cold air to cover all areas and significantly improving the uniformity of temperature distribution.

[0149] The number of the second air outlet 28 and the third air outlet 29 can both be set to three. The second air duct 4 is equipped with a second air volume regulator 42, and the third air duct 5 is equipped with a third air volume regulator. By controlling the second air volume regulator 42 and the third air volume regulator, the latter two of the three second air outlets 28 and the third air outlet 29 can be blocked. By controlling the number of air outlets opened, the amount of cold air entering the drawer can be controlled, thereby achieving adaptive adjustment of the air volume at level one, level two, or level three to meet different load requirements.

[0150] The second and third airflow adjustment components are in the form of baffles. The drive mechanism is electrically connected to the controller 72. The control module is integrated into the refrigerator's main control board. The signal is connected to the temperature detection device 71 and pressure sensor located inside the refrigerator drawer, which are used to monitor the temperature changes and food load inside the drawer in real time.

[0151] When the controller detects an increase in the weight of the food in the drawer or a sudden rise in temperature, the controller 72 automatically controls the sliding of the second air volume regulator 42 and the third air volume regulator, and the second air outlet 28 and the third air outlet 29 are fully opened to increase the air volume and enter the strong wind quick freeze mode.

[0152] Once the temperature inside the drawer drops to the set value, the controller 72 controls the second and third airflow regulators 42 to close the two rear air outlets, at which point the drawer switches to energy-saving mode. By controlling the position of the baffle, multi-level adaptive control of the airflow is achieved, taking into account cooling performance, energy efficiency, and operating noise under different operating conditions.

[0153] Users can also select "Quick Freeze", "Energy Saving" or "Silent" mode through the control panel, and the system will automatically match the corresponding air volume to achieve intelligent and personalized air supply control.

[0154] Related technologies employ internally welded wires or externally connected junction boxes for power supply, while this application's embodiment uses a spring contact power supply method. Multiple metal spring contacts are provided at the bottom of the drawer body. These spring contacts are precision spring structures with high elasticity and high conductivity. Electrode plates matching the spring contacts are located at corresponding positions on the drawer support inside the freezer compartment.

[0155] When the drawer is placed inside the cabinet, the spring contacts and the electrode plate achieve stable and reliable elastic contact. The drawer slides along with the drawer support, and the spring contacts and the electrode plate always remain in contact, thereby continuously supplying power to all electronic components inside the drawer and transmitting signals.

[0156] The combination of spring contacts and electrode plates eliminates the need for traditional methods such as welding wires inside drawers or using external junction boxes. It offers advantages such as no welding, no wiring, and plug-and-play functionality, greatly simplifying the assembly process and improving production efficiency and product consistency.
