Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a storage rack and refrigeration equipment. Background Technology

[0002] Refrigeration equipment absorbs heat through the phase change cycle of refrigerant, lowering and maintaining the temperature within an enclosed space to preserve food, medicine, or other items, or to provide cooling. The cool air within the refrigeration equipment is guided to the storage room through an air duct system to ensure a consistently low-temperature environment throughout the storage room. The refrigeration equipment's fan operates continuously, causing the cool air to circulate constantly, thus maintaining the low-temperature environment within the storage room.

[0003] The air outlets of existing refrigeration equipment are usually located at the back of the storage room. Cold air flows out from the air outlets at the back of the storage room, circulates inside the storage room, and then returns to the fan.

[0004] However, due to the depth of the storage compartment, there is often a significant temperature difference between the end near the back of the compartment and the end furthest away. This not only affects storage efficiency but may also lead to localized insufficient cooling in certain areas. Especially when items are placed on the shelves, they can block the air vents at the back of the compartment, hindering effective airflow and resulting in uneven temperature distribution within the storage room. Utility Model Content

[0005] In view of the above problems, this application provides a storage rack and a refrigeration device, which helps to achieve a uniform distribution of air volume in the storage room, so as to ensure the consistency of the storage room temperature.

[0006] In a first aspect, this application provides a storage rack for a refrigeration device. The storage rack has an air supply cavity and an air inlet and an air outlet communicating with the air supply cavity. The air inlet is used to connect to the refrigeration air duct of the refrigeration device, and the air outlet is used to connect to the storage compartment of the refrigeration device. The storage rack is also provided with a partition, which divides the air supply cavity into multiple air supply areas, and each air supply area is provided with the air outlet.

[0007] In this way, cool air can be delivered to the storage room through the air vents of the shelving unit. The internal ribs of the shelving unit divide the air delivery chamber into multiple air delivery zones, ensuring a balanced distribution of cool air across these zones and avoiding the temperature difference issues caused by a single air outlet in traditional designs. Furthermore, each air delivery zone has its own air vents, effectively preventing airflow obstruction when items are stacked on top of the shelving unit, improving cooling efficiency, ensuring a consistent temperature within the storage room, and preventing localized temperature imbalances.

[0008] In one possible implementation, the partition includes a first partition disposed between two adjacent air supply zones to separate the two adjacent air supply zones.

[0009] This ensures that airflow within each air supply zone is independent and does not interfere with each other, achieving a uniform distribution of cold air throughout the zone. The first baffle prevents cross-flow of cold air between different air supply zones, thus preventing excessive localized concentration of cold air or insufficient cooling in certain areas. Furthermore, the presence of the first baffle enhances the stability of the shelf's internal structure.

[0010] In one possible implementation, the shelf is provided with a plurality of air inlets corresponding to the air supply area.

[0011] This ensures that each air supply zone can receive cold air independently and evenly from the refrigeration unit. By equipping each air supply zone with a corresponding air inlet, multiple points of cold air can be introduced, avoiding the problem of uneven airflow caused by a single air inlet and improving the circulation efficiency of cold air inside the shelf.

[0012] In one possible implementation, the plurality of said air supply zones are distributed along a first direction and / or a second direction.

[0013] In this way, by arranging multiple air supply zones on the shelf in a predetermined direction (such as the first direction and / or the second direction), it can be ensured that cold air can be released evenly over a larger area, avoiding the problem of uneven local cooling caused by a single or concentrated air outlet.

[0014] In one possible implementation, a plurality of the air supply zones are distributed along the second direction, and each air supply zone includes a plurality of sub-regions distributed along the first direction.

[0015] This further ensures the uniform distribution of cold air and consistent temperature within the storage room. By setting multiple air supply zones in the second direction, and further subdividing each air supply zone into several sub-zones distributed along the first direction, cold air can be released in multiple dimensions within the storage room, increasing the coverage of the airflow.

[0016] In one possible implementation, the rib further includes: a plurality of second ribs corresponding one-to-one with the sub-regions, each second rib at least partially surrounding the corresponding sub-region.

[0017] This further enhances the independence and stability of airflow within each sub-region. The surrounding design of the second baffle effectively prevents airflow crosstalk between adjacent sub-regions, avoiding problems such as excessive localized cold air concentration within the supply air area or insufficient cold air in certain sub-regions.

[0018] In one possible implementation, the height of the second baffle is less than the height of the air supply cavity, and the height of the plurality of second baffles corresponding to the same air supply area increases sequentially in the direction along the first direction and away from the air inlet.

[0019] In this way, by setting up a second baffle that gradually increases in height, cold air entering the air supply cavity will first fill the sub-area where the lower-height second baffle is located. As the airflow advances, the cold air will gradually flow to the sub-area where the higher-height second baffle is located, thus achieving gradual air supply from the air inlet to the far end of the air supply cavity. This effectively prevents the airflow from being excessively concentrated at the near end of the air supply cavity while the cooling capacity at the far end is insufficient. In addition, the height difference design of the second baffle enhances the sense of layering and fluidity of the airflow, ensuring that each sub-area receives a uniform and stable supply of cooling capacity.

[0020] In one possible implementation, the first partition is located on the bottom wall of the shelf, and / or the second partition is located on the top wall of the shelf.

[0021] Thus, by placing the first baffle on the bottom wall of the shelf, adjacent air supply areas can be effectively separated, while placing the second baffle on the top wall of the shelf can better guide the flow direction of cold air, allowing the airflow to diffuse evenly downwards from the top wall. In addition, the vertical arrangement of the first and second baffles also enhances the stability of the internal structure of the shelf.

[0022] In one possible implementation, the plurality of air supply zones include at least a first air supply zone and a second air supply zone, wherein the second air supply zone surrounds the periphery of the first air supply zone.

[0023] In this way, by surrounding the first air supply zone with the second air supply zone, a multi-layered air supply structure can be formed to ensure that the cold air can be evenly diffused and also to help reduce temperature fluctuations.

[0024] In one possible implementation, the shelf further includes an air damper device located at the air inlet, the air damper device being used to control the opening and closing of the air inlet and the size of the opening.

[0025] In this way, by controlling the air inlet through the damper device, the air volume in the air supply area can be dynamically adjusted according to actual needs, thus avoiding unnecessary energy waste.

[0026] In one possible implementation, there are multiple air inlets, and the damper devices correspond to the air inlets. The multiple damper devices are configured to operate independently of each other.

[0027] In this way, the damper devices correspond to the air inlets, and each damper device works independently, allowing each damper device to independently adjust the opening and closing status and opening size of the air inlet, so as to achieve on-demand air supply to different air supply areas, thereby ensuring uniform temperature in the storage room.

[0028] In one possible implementation, the shelf further includes: a temperature detection device for detecting the temperature of the storage compartment; and a control device communicatively connected to both the temperature detection device and the damper device, wherein the control device is configured to control the operating state of the damper device based on the detection result of the temperature detection device.

[0029] This enhances the intelligence level of the refrigeration equipment, ensuring precise control and uniform distribution of temperature within the storage room. By monitoring temperature changes in real time through temperature detection devices, the control system can intelligently analyze the monitoring data and dynamically adjust the opening and closing status and size of each damper to achieve on-demand airflow and prevent energy waste.

[0030] In one possible implementation, the air inlet is located on the bottom wall or side wall of the shelf.

[0031] This optimizes the introduction and distribution of cold air, improving the overall performance of the refrigeration equipment. Placing the air inlet on the bottom or side wall of the shelf allows it to adapt to different airflow zones, reducing airflow resistance and cooling loss.

[0032] In one possible implementation, the shelf includes: a base shell having an opening at its top; a shelf covering the opening and defining the air supply cavity together with the base shell; the air supply holes being formed in the bottom wall of the base shell; and the shelf for holding items.

[0033] In this way, placing the air vents on the bottom wall of the base shell allows cold air to directly penetrate the base shell and reach all areas of the storage compartment, enhancing the uniformity of airflow coverage and the cooling effect. Furthermore, the shelf not only serves as a platform for carrying items but also acts as a cover for the air vents, ensuring the stability and reliability of the airflow path.

[0034] In one possible implementation, the shelf is at least one of glass, plastic, and metal.

[0035] Thus, the materials for the storage panels are widely available, easy to process, and have low costs.

[0036] In one possible implementation, the shelf further includes: a heat insulation member disposed between the bottom shell and the shelf, the heat insulation member being connected to the open end face of the bottom shell and the shelf, and the partition ribs being disposed on at least one of the bottom shell and the heat insulation member.

[0037] Thus, by adding a heat insulation element between the bottom shell and the shelf, condensation caused by excessive temperature difference between the inside and outside of the shelf is avoided. The presence of the heat insulation element forms an additional thermal resistance layer, reducing the speed at which cold air is directly transferred from the air supply cavity to the shelf, preventing the shelf temperature from becoming too low, and thus reducing the possibility of water vapor condensing on the shelf.

[0038] Secondly, this application provides a refrigeration device, comprising: a housing having a storage compartment; an air duct component disposed in the storage compartment, the air duct component defining a refrigeration air duct; and a shelf as described in any of the above possible implementations, wherein the shelf is a plurality of shelves arranged vertically at intervals in the storage compartment, the shelf is used to place items, and the air supply cavity of the shelf is respectively connected to the refrigeration air duct and the storage compartment.

[0039] In this way, by arranging multiple shelves vertically at intervals along the storage room, it can be ensured that cold air can be evenly and directly delivered to each shelf in the storage room. Furthermore, the air supply chambers of the shelves are connected to the cooling ducts and the storage room, which allows the cold air to be evenly distributed within the storage room, ensuring temperature consistency and airflow uniformity throughout the entire storage space.

[0040] The storage rack and refrigeration equipment provided in this application can directly deliver cool air to the storage room through the air outlets of the storage rack. The internal baffles of the storage rack divide the air supply chamber into multiple air supply zones, achieving a balanced distribution of cool air across different areas and avoiding the temperature difference problem caused by a single air outlet in traditional designs. Furthermore, each air supply zone has its own air outlet, effectively preventing airflow obstruction when items are stacked on top of the rack, improving refrigeration efficiency, ensuring a consistent temperature within the storage room, and preventing localized temperature unevenness.

[0065] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0066] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0067] In existing refrigeration equipment, the air outlets are typically located at the back of the storage compartment. Cool air flows out from these outlets, circulates within the compartment, and returns to the fan. However, due to the depth of the storage compartment, a significant temperature difference often exists between the end near the back and the end furthest away. This not only affects storage efficiency but can also lead to localized insufficient cooling in certain areas. Especially when items are placed on the shelves, they can obstruct the air outlets at the back of the compartment, hindering effective airflow and resulting in uneven temperature distribution within the storage compartment.

[0068] In view of this, this application provides a storage rack and a refrigeration device. By connecting the air inlet of the storage rack to the refrigeration duct of the refrigeration device and connecting the air outlet of the storage rack to the storage compartment, cold air can be efficiently introduced and evenly distributed. The internal baffles of the storage rack can divide the air outlet chamber into multiple independent air outlet areas, and each area is equipped with an air outlet, which can realize multi-point and multi-level airflow release, avoid the problem of uneven local cooling, and ensure the consistency of the temperature in the storage compartment.

[0069] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These 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 this application will now be described with reference to the accompanying drawings:

[0070] It should be noted that the storage rack provided in this application embodiment can be applied to various refrigeration equipment, such as household refrigerators, commercial refrigerators, and industrial refrigeration equipment.

[0071] In one possible design, the refrigeration equipment may include a compressor, condenser, expansion valve, evaporator, and fan. During operation, the refrigerant enters the compressor at low pressure and is compressed into a high-temperature, high-pressure gas. During this process, the refrigerant's temperature and pressure increase significantly. The high-temperature, high-pressure refrigerant then enters the condenser and exchanges heat with the outside air or the outer casing of the refrigeration equipment, releasing heat and cooling down. As the temperature decreases, the refrigerant gradually liquefies, becoming a high-temperature, high-pressure liquid. Subsequently, the liquid refrigerant passes through the expansion valve, causing a rapid drop in pressure and temperature. The low-temperature, low-pressure refrigerant then evaporates in the evaporator, absorbing heat from the cold storage compartment. Finally, the fan delivers the cooled air from the evaporator into the storage compartment of the refrigeration equipment, creating cool air and achieving the cooling effect.

[0072] The storage rack provided in this embodiment can be used in refrigeration equipment. The refrigeration equipment includes a refrigeration duct. The refrigeration duct can be located at the back of the refrigeration equipment. Cold air can enter the storage compartment of the refrigeration equipment through the refrigeration duct.

[0073] refer to Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 The shelf 1 has an air supply cavity 10, an air inlet 20, an air outlet 30, and a partition 40. The air inlet 20 and the air outlet 30 can be located at different positions on the shelf 1. The air inlet 20 and the air outlet 30 can each communicate with the air supply cavity 10 of the shelf 1. The shelf 1 can communicate with the refrigeration duct of the refrigeration equipment through the air inlet 20. The shelf 1 can also communicate with the storage compartment 201 of the refrigeration equipment through the air outlet 30. Optionally, the air supply cavity 10 can be rectangular, square, circular, etc., and the specific shape of the air supply cavity 10 can be determined according to actual needs; this application does not impose any limitations. A guide vane can also be installed inside the air supply cavity 10. The guide vane can guide the cold air to flow along a predetermined path, avoiding excessive concentration or uneven dispersion of local airflow. The angle and position of the guide vane can be adjusted according to actual needs to optimize the airflow path. An adjustable baffle can also be installed inside the air supply cavity 10. The adjustable baffle can flexibly adjust the airflow direction and intensity according to the actual storage situation.

[0074] Furthermore, the partitions 40 in the shelf 1 can divide the air supply cavity 10 into multiple air supply zones 110. Each air supply zone 110 is provided with an air supply hole 30. Optionally, the number and size of the air supply zones 110 can be gradually distributed within the air supply cavity 10. For example, the air supply zone 110 near the air inlet 20 can be smaller, while the air supply zone 110 away from the air inlet 20 can be larger to compensate for the weakened airflow. Some of the multiple air supply zones 110 can also be designed for directional air supply, directly delivering cold air to specific locations, such as the key preservation areas on the shelf 1, through guide vanes or nozzles.

[0075] Understandably, cool air can be delivered to the storage compartment 201 through the air outlet 30 of the shelf 1. The internal baffles 40 of the shelf 1 divide the air outlet 10 into multiple air outlet zones 110, achieving a balanced distribution of cool air across these zones and avoiding the temperature difference issues caused by a single air outlet in traditional designs. Furthermore, each air outlet zone 110 is equipped with an air outlet 30, effectively preventing airflow obstruction when items are stacked on top of the shelf 1, improving cooling efficiency, ensuring temperature consistency within the storage compartment 201, and preventing localized temperature unevenness within the storage compartment 201.

[0076] In one possible implementation, refer to Figure 7 , Figure 8 The partition 40 includes a first partition 410. The first partition 410 can be disposed between two adjacent air supply zones 110, thereby separating the two adjacent air supply zones 110. Optionally, multiple first partitions 410 can be disposed between two adjacent air supply zones 110. For example, two first partitions 410 can be disposed between two adjacent air supply zones 110. Furthermore, each air supply zone 110 is provided with two first partitions 410. The two first partitions 410 within each air supply zone 110 can be arranged in parallel, intersecting, or other ways, depending on actual needs, and this application does not impose any restrictions.

[0077] Furthermore, the first partition 410 can abut against the inner wall of the shelf 1 to form a relatively enclosed air supply area 110. Alternatively, there can be a gap between the first partition 410 and the inner wall of the shelf 1 to form a partially enclosed air supply area 110. Similarly, the height of the first partition 410 can be equal to the height of the air supply cavity 10. Alternatively, the height of the first partition 410 can be less than the height of the air supply cavity 10. In addition, the first partition 410 can be designed to be adjustable, allowing the user to flexibly adjust the position and angle of the partition 40 according to the actual storage situation to adapt to different usage needs.

[0078] Understandably, by setting the first baffle 410, the airflow within each air supply zone 110 can be ensured to be independent and non-interfering, achieving a uniform distribution of cold air within each air supply zone 110. Through the separating effect of the first baffle 410, cross-flow of cold air between different air supply zones 110 is avoided, thus preventing problems such as excessive local concentration of cold air or insufficient cold air in certain areas. Furthermore, the presence of the first baffle 410 also enhances the stability of the internal structure of the shelf 1.

[0079] In one possible implementation, refer to Figure 7 , Figure 8 , Figure 10 , Figure 11 The shelf 1 is also equipped with multiple air inlets 20. Each air supply area 110 of the shelf 1 corresponds to one air inlet 20. Alternatively, each air supply area 110 can correspond to multiple air inlets 20. Optionally, the air inlets 20 can be circular, rectangular, slit-type, or mesh, etc. The shape of the air inlets 20 can be determined according to actual needs, and this application does not impose any limitations. Furthermore, the air inlets 20 can be located on the bottom wall of the shelf 1, allowing cold air to enter the air supply cavity 10 from below, forming a natural convection circulation. Alternatively, the air inlets 20 can be located on the side wall of the shelf 1, thus allowing for flexible adjustment of the airflow direction according to the specific layout of the storage room 201. Or, the air inlets 20 can also be located on the top wall of the shelf 1, allowing cold air to enter the air supply cavity 10 from above, forming a top-to-bottom airflow path.

[0080] Optionally, the shelf 1 may also include multiple air duct adapters 80. Each air duct adapter 80 may correspond one-to-one with a plurality of air inlets 20. Alternatively, each air duct adapter 80 may correspond to multiple air inlets 20. The air duct adapter 80 is used to connect the air inlets 20 and the cooling air duct. The air duct adapter 80 may be a housing component with a specific shape. The air duct adapter 80 may have two connection ports. The air duct adapter 80 may be snapped into the outlet of the cooling air duct. One connection port of the air duct adapter 80 may be inserted into the cooling air duct, and the other connection port may be inserted into the air inlet 20. Specifically, most of the structure of the air duct adapter 80 may be inserted into the cooling air duct to increase the cross-sectional area of ​​the connection port connected to the cooling air duct, thereby increasing the flow rate of cold air. Another insertion end with a connection port may also extend from the air duct adapter 80. This insertion end may be inserted into the air inlet 20. In this case, the air inlet 20 may be located on the side of the bottom shell 50. Alternatively, most of the structure of the air duct adapter 80 can be fixed to the side wall of the housing 2 and located below the shelf 60 to support the shelf 1, thereby improving the load-bearing capacity of the shelf 1. The air duct adapter 80 can extend two insertion ends with connection ports, which are respectively inserted into the cooling air duct and the air inlet 20 of the shelf 1. In this case, the air inlet 20 can be located at the bottom of the bottom shell 50. Alternatively, part of the structure of the air duct adapter 80 can be fixed inside the cooling air duct, and the other part of the structure of the air duct adapter 80 can extend into the storage compartment 20. The part of the air duct adapter 80 extending into the storage compartment 20 can have a fixing groove formed on it. The shelf 60 can be slidably disposed in the fixing groove. In this case, the air inlet 20 can be located at the bottom or side of the bottom shell 50.

[0081] Understandably, the design of multiple air inlets 20 ensures that each air supply zone 110 can independently and evenly receive cold air from the refrigeration equipment. By equipping each air supply zone 110 with a corresponding air inlet 20, multiple points of cold air can be introduced, avoiding the problem of uneven airflow caused by a single air inlet 20, and improving the circulation efficiency of cold air inside the shelf 1.

[0082] In one possible implementation, refer to Figure 7 , Figure 8 Multiple air supply zones 110 are distributed along a first direction. Alternatively, multiple air supply zones 110 are distributed along a second direction. Or, multiple air supply zones 110 are distributed along both the first and second directions.

[0083] It should be noted that the first direction can be perpendicular to the back panel of the refrigeration equipment, and the second direction can be perpendicular to the first direction and extend horizontally. Alternatively, the first direction can be an extension along the width of the shelf 1, and the second direction can be an extension along the length of the shelf 1.

[0084] It is understandable that by arranging multiple air supply zones 110 on the shelf 1 in a predetermined direction (such as the first direction and / or the second direction), it can be ensured that cold air can be released evenly over a larger area, avoiding the problem of uneven local cooling caused by a single or concentrated air outlet.

[0085] In one possible implementation, refer to Figure 7 , Figure 8 Multiple air supply zones 110 are distributed along a second direction. Furthermore, each air supply zone 110 includes several sub-zones 111. The sub-zones 111 within each air supply zone 110 can be distributed along a first direction. Optionally, the sub-zones 111 within each air supply zone 110 can be evenly distributed along the first direction. Alternatively, the distribution density of the sub-zones 111 within each air supply zone 110 can gradually change. For example, the sub-zones 111 closer to the air inlet 20 are more densely distributed, while the sub-zones 111 further away from the air inlet 20 gradually become sparser.

[0086] In one possible design, the sub-regions 111 within each air supply zone 110 can also be designed in different shapes, such as circular, rectangular, or elliptical. Different shaped sub-regions 111 can optimize the flow path of cold air according to actual needs; for example, a circular sub-region 111 can reduce airflow resistance, while a rectangular sub-region 111 can provide a larger air intake area. Furthermore, the size of the sub-regions 111 can be adjusted according to different parts of the shelf 1. Some areas of the shelf 1 may have larger sub-regions 111, while other areas may have smaller sub-regions 111. Larger sub-regions 111 are suitable for areas requiring a larger cooling capacity, while smaller sub-regions 111 allow for more precise temperature control.

[0087] This further ensures the uniform distribution and temperature consistency of cold air within the storage room 201. By setting multiple air supply zones 110 in the second direction, and further subdividing each air supply zone 110 into several sub-zones 111 distributed along the first direction, cold air can be released in multiple dimensions within the storage room 201, thus improving the coverage of the airflow.

[0088] In one possible implementation, the partition 40 further includes a plurality of second partitions. Each second partition may correspond one-to-one with a sub-region 111. Furthermore, each second partition may partially surround its corresponding sub-region 111. For example, the second partition may only surround a portion of the edge of the sub-region 111. Specifically, the second partition may surround the inner edge of the sub-region 111. The second partition may also surround the outer edge of the sub-region 111. Alternatively, each second partition may completely surround its corresponding sub-region 111. When the second partition completely surrounds its corresponding sub-region 111, ventilation holes may be provided on the second partition.

[0089] Optionally, the second partition can be fixedly connected to the main body of the shelf 1. Alternatively, the second partition can be movably connected to the main body of the shelf 1, allowing the user to adjust the position and angle of the second partition according to actual needs to adapt to different usage scenarios. The second partition can also be connected to the main body of the shelf 1 via an intermediate connector. The intermediate connector can be a bracket or a buckle. The second partition can also be directly embedded into the main body of the shelf 1 or the bottom shell 50 to form a seamless connection structure.

[0090] Understandably, by setting the second baffle, the independence and stability of airflow within each sub-region 111 can be further enhanced. The surrounding design of the second baffle can effectively prevent airflow crosstalk between adjacent sub-regions 111, avoiding the problems of excessive local concentration of cooling capacity within the air supply area 110 or insufficient cooling capacity in some sub-regions 111 within the air supply area 110.

[0091] In one possible implementation, the height of the second baffle may be less than the height of the air supply cavity 10 to facilitate the passage of cold air. Furthermore, the heights of multiple second baffles within the same air supply area 110 may vary gradually. For example, the height of the second baffle may gradually increase along the first direction and away from the air inlet 20. In this way, the second baffle can concentrate cold air in its corresponding sub-area 111 to improve the cooling effect. When the cold air in the sub-area 111 containing the second baffle reaches a certain level, the cold air can enter the next sub-area 111 containing the second baffle.

[0092] Alternatively, the height of the second baffle can be equal to the height of the air supply cavity 10. To ensure that cold air can pass smoothly through the second baffle and enter other sub-areas 111, the second baffle can have a top opening structure. The second baffle can also be provided with adjustable openings. The second baffle can also be provided with a top guide plate.

[0093] Understandably, by setting up gradually increasing second baffles, after cold air enters the air supply cavity 10, it will first fill the sub-region 111 where the lower-height second baffle is located. As the airflow advances, the cold air will gradually flow to the sub-region 111 where the higher-height second baffle is located, thus achieving gradual air supply from the air inlet 20 to the far end of the air supply cavity 10, effectively preventing the situation where the airflow is excessively concentrated at the near end of the air supply cavity 10 while the cooling capacity at the far end is insufficient. In addition, the height difference design of the second baffles enhances the sense of layering and fluidity of the airflow, so that each sub-region 111 can obtain a uniform and stable cooling capacity supply.

[0094] In one possible implementation, refer to Figure 7 , Figure 8 , Figure 9 The first partition 410 can be set on the bottom wall of the shelf 1. Alternatively, the second partition 410 can be set on the top wall of the shelf 1. Or, the first partition 410 can be set on the bottom wall of the shelf 1, and the second partition 410 can be set on the top wall of the shelf 1.

[0095] Understandably, by placing the first baffle 410 on the bottom wall of the shelf 1, adjacent air supply areas 110 can be effectively separated, while placing the second baffle on the top wall of the shelf 1 can better guide the flow direction of cold air, allowing the airflow to diffuse evenly downwards from the top wall. In addition, the vertical arrangement of the first baffle 410 and the second baffle also enhances the stability of the internal structure of the shelf 1.

[0096] In one possible implementation, refer to Figure 9 The multiple air supply zones 110 may also include a first air supply zone 112 and a second air supply zone 113. The first air supply zone 112 may be located within the second air supply zone 113. The second air supply zone 113 is arranged around the first air supply zone 112.

[0097] Optionally, the first air supply zone 112 can be located at the center of the shelf 1, and the first air supply zone 112 can be circular or elliptical. The second air supply zone 113 can be arranged around the first air supply zone 112, and the second air supply zone 113 can form a ring structure. Alternatively, the first air supply zone 112 can be located at the center of the shelf 1, and is rectangular or square. The second air supply zone 113 can surround the first air supply zone 112, forming a larger rectangular or square structure. Alternatively, the first air supply zone 112 can be located at the center of the shelf 1, and is circular or elliptical. The second air supply zone 113 can surround the first air supply zone 112, forming a spiral structure. The spiral layout ensures that cold air gradually diffuses from the center to the periphery, and the spiral path effectively reduces temperature differences and improves temperature uniformity.

[0098] In one possible design, the air inlet 20 can be located on either side or one side of the shelf 1. Optionally, when cold air enters the air supply cavity 10 from either side of the shelf 1, it can be guided to the first air supply zone 112 and the second air supply zone 113 by the annular first baffle 410. Alternatively, when cold air enters the air supply cavity 10 from one side of the shelf 1, it can be guided to the first air supply zone 112 and the second air supply zone 113 by the guide vane.

[0099] Understandably, by surrounding the first air supply zone 112 with the second air supply zone 113, a multi-layered air supply structure can be formed to ensure that the cold air can be evenly diffused and also to help reduce temperature fluctuations.

[0100] In one possible implementation, the shelf 1 further includes an air damper. The air damper can be located at the air inlet 20 of the shelf 1. The air damper can control the opening and closing of the air inlet 20 and its opening size. Optionally, the air damper can be a manual damper. The user can control the opening and closing of the damper and the opening size through manual operation (such as rotation or sliding). Alternatively, the air damper can be an automatic damper. Combined with an intelligent control system, the damper can automatically adjust its opening and closing status and opening size based on real-time temperature feedback.

[0101] Furthermore, the damper device can be installed at one side air inlet 20 of the shelf 1, and is responsible for controlling the opening and closing and the size of the opening of the air inlet 20 on that side. Alternatively, the damper device can be installed at the air inlets 20 on both sides of the shelf 1, and is responsible for controlling the opening and closing and the size of the opening of the air inlets 20 on both sides.

[0102] Understandably, by controlling the air inlet 20 through the damper device, the air volume of the air supply area 110 can be dynamically adjusted according to actual needs, thus avoiding unnecessary energy waste.

[0103] In one possible implementation, refer to Figure 7 , Figure 8 , Figure 10 , Figure 11 The number of air inlets 20 can be multiple. Furthermore, damper devices can correspond to the air inlets 20. Multiple damper devices can also operate independently of each other, or they can cooperate with each other.

[0104] It is understandable that the damper devices correspond to the air inlets 20, and each damper device works independently, so that each damper device can independently adjust the opening and closing state and opening size of the air inlets 20 to achieve on-demand air supply to different air supply areas 110, thereby ensuring uniform temperature in the storage room 201.

[0105] In one possible implementation, the shelf 1 further includes a temperature detection device and a control device. The temperature detection device is used to detect the temperature of the storage compartment 201. The control device can be communicatively connected to both the temperature detection device and the damper device. Furthermore, the control device is configured to control the operating state of the damper device based on the detection result from the temperature detection device.

[0106] Optionally, the temperature detection device can be a contact temperature sensor, a non-contact temperature sensor, an integrated temperature sensor, etc. The temperature detection device can be installed at the air inlet 20 of the shelf 1. Alternatively, the temperature detection device can be distributed at multiple points within the shelf 1.

[0107] Understandably, temperature detection and control devices can enhance the intelligence level of refrigeration equipment, ensuring precise control and uniform temperature distribution within storage room 201. By monitoring temperature changes in storage room 201 in real time through the temperature detection device, the control device can intelligently analyze the monitoring data and dynamically adjust the opening and closing status and opening size of each damper device to achieve on-demand air supply and avoid energy waste.

[0108] In one possible implementation, refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The air inlet 20 can be located on the bottom wall of the shelf 1. Alternatively, the air inlet 20 can be located on the side wall of the shelf 1. The location of the air inlet 20 can be determined according to actual needs, and this application does not impose any restrictions.

[0109] Understandably, optimizing the introduction path and distribution of cold air can improve the overall performance of the refrigeration equipment. By placing the air inlet 20 on the bottom or side wall of the shelf 1, the air inlet 20 can be adapted to the layout of different air supply areas 110, thereby reducing airflow resistance and cold energy loss.

[0110] In one possible implementation, refer to Figure 7 , Figure 8 , Figure 9 The shelf 1 also includes a base shell 50 and a shelf panel 60. The base shell 50 has an opening at its top. The shelf panel 60 can be placed above the base shell 50 to cover the opening. The shelf panel 60, together with the base shell 50, defines the air supply cavity 10 of the shelf 1. Air supply holes 30 for the shelf 1 can be formed on the bottom wall of the base shell 50. The shelf panel 60 can be used to hold items.

[0111] Understandably, placing the air outlet 30 on the bottom wall of the bottom shell 50 allows cold air to directly penetrate the bottom shell 50 and reach all areas within the storage compartment 201, enhancing the uniformity of airflow coverage and the cooling effect. Furthermore, the shelf 60 not only serves as a platform for carrying items but also acts as a cover for the air outlet cavity 10, ensuring the stability and reliability of the airflow path.

[0112] In one possible implementation, the shelf 60 is at least one of glass, plastic, and metal. Thus, the shelf 60 is made from widely available materials, is easy to process, and has a low cost.

[0113] Glass provides sufficient strength and load-bearing capacity to ensure the stability and safety of the shelf 60 when carrying items. Furthermore, the smooth surface of glass does not easily attract dirt, making cleaning relatively simple. Users can easily wipe the glass surface to keep the shelf 60 clean and hygienic. Plastic parts are lower in cost and lighter in weight; metal parts have higher structural strength and a longer service life.

[0114] In one possible implementation, refer to Figure 10 , Figure 11 The shelf 1 also includes a heat insulation component 70. The heat insulation component 70 can be disposed between the bottom shell 50 and the shelf 60. The heat insulation component 70 can be connected to the end face of the open end of the bottom shell 50 and the shelf 60 respectively to achieve a heat insulation effect and prevent the shelf 60 from becoming too cold. Furthermore, a partition 40 can be disposed on the bottom shell 50. Alternatively, the partition 40 can be disposed on the heat insulation component 70. Or, the partition 40 can be disposed on both the bottom shell 50 and the heat insulation component 70. For example, a first partition 410 can be disposed on the bottom shell 50, and a second partition 410 can be disposed on the heat insulation component 70.

[0115] Understandably, by adding a heat insulation element 70 between the bottom shell 50 and the shelf 60, condensation caused by excessive temperature difference between the inside and outside of the shelf 60 is avoided. The presence of the heat insulation element 70 forms an additional thermal resistance layer, reducing the speed at which cold air is directly conducted from the air supply cavity 10 to the shelf 60, ensuring that the temperature of the shelf 60 does not drop too low, thereby reducing the possibility of water vapor condensing on the shelf 60.

[0116] On the other hand, reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6This application provides a refrigeration device, including a housing 2, an air duct 3, and the aforementioned shelf 1. The housing 2 contains a storage compartment 201. The storage compartment 201 can be used to store items requiring low-temperature preservation, such as food. The air duct 3 can be disposed within the storage compartment 201. For example, the air duct 3 can be disposed on the back panel of the storage compartment 201. The air duct 3 can define a refrigeration air duct. The air supply cavity 10 of the shelf 1 can communicate with both the refrigeration air duct and the storage compartment 201. Furthermore, the shelf 1 is used to place items, and there can be multiple shelves 1. Multiple shelves 1 can be distributed vertically at intervals within the storage compartment 201.

[0117] It is understandable that by arranging multiple shelves 1 vertically at intervals along the storage compartment 201, it can be ensured that cold air can be evenly and directly delivered to each shelf in the storage compartment 201. Furthermore, the air supply chambers 10 of the shelves 1 are connected to the cooling duct and the storage compartment 201 respectively, which can make the cold air evenly distributed in the storage compartment 201, ensuring temperature consistency and airflow uniformity throughout the entire storage space.

[0118] refer to Figure 10 , Figure 11 The air duct component 3 may include a metal plate and a foam board. A cooling air duct is formed on the foam board to facilitate the circulation of cold air. Further, the metal plate is positioned closer to the shelf 1, and the foam board is positioned further away from the shelf 1. Ventilation holes may also be provided on the metal plate. These ventilation holes correspond to the cooling air ducts on the foam board to ensure smooth circulation of cold air.
