Description
Technical Field
[0001] This utility model relates to the field of pull-out basket technology, specifically to a side-mounted refrigerated lift-up pull-out basket and storage cabinet. Background Technology
[0002] With the increasing demands for space utilization efficiency and functional integration in modern kitchens, pull-out basket systems have become widely used due to their convenience. To meet the need for refrigeration, pull-out basket products with integrated refrigeration functions have emerged in this field.
[0003] In existing technologies, a common practice is to place the refrigeration and ventilation modules at the back of the refrigerator to maintain a neat appearance. However, this traditional layout has significant drawbacks: First, it severely occupies the system's depth space, making it difficult for the product to fit standard-sized wall cabinets, or greatly compressing the actual internal storage volume, contradicting the original intention of improving space utilization. Second, when the core functional module malfunctions, maintenance is extremely inconvenient, usually requiring the entire pull-out basket system to be disassembled and partially dismantled from the cabinet, a cumbersome and costly process. Furthermore, in the enclosed environment of a wall cabinet, the heat dissipation path of the rear module is obstructed, easily leading to heat accumulation, which not only affects cooling efficiency and energy consumption, but may also jeopardize the long-term stability of the system and the lifespan of components.
[0004] Therefore, existing technologies urgently need an innovative solution to effectively address challenges related to space, maintenance, and heat dissipation while integrating refrigeration and heat dissipation functions. Summary of the Invention
[0005] The first objective of this utility model is to overcome the shortcomings of existing refrigerated lifting baskets, such as low space utilization, inconvenient maintenance, and poor heat dissipation efficiency, and to provide a side-mounted refrigerated lifting basket.
[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0007] A side-mounted refrigerated lift-up basket includes a lift-up frame, a refrigerated box, and a heat dissipation system. The refrigerated box is located within the lift-up frame and includes an inner liner and an outer casing covering the inner liner. The heat dissipation system includes a refrigeration module, a heat dissipation module, and a heat dissipation duct. The refrigeration module is located between the outer casing and the inner liner and has a refrigeration end and a heat dissipation end. The refrigeration end is thermally connected to the outer side wall of the inner liner. The heat dissipation module is located above the refrigeration module. The heat dissipation duct is located between the outer casing and the inner liner, with its air inlet located at the top of the refrigerated box and its air outlet located at the bottom of the refrigerated box. The heat dissipation end of the refrigeration module and the heat dissipation module are located on the heat dissipation duct.
[0008] This utility model provides a side-mounted refrigerated lift-up basket. Its technical principle lies in: integrating the refrigeration module laterally between the inner liner and outer casing of the refrigerator, allowing the refrigeration end to directly conduct heat to the inner liner's side wall for refrigeration. Simultaneously, a heat dissipation module located above the refrigeration module drives airflow along a top-to-bottom heat dissipation duct formed between the inner liner and outer casing. After absorbing heat at the refrigeration module's heat dissipation end, the hot air is finally discharged directly to the outside of the refrigerator from the bottom outlet. This solution achieves three core effects: First, the lateral integration layout greatly optimizes the utilization of depth space, making the product more compatible with standard cabinets; second, the clearly defined forced heat dissipation duct leading to the outside effectively prevents heat accumulation inside the cabinet, significantly improving heat dissipation efficiency and system stability; third, the module's concentration on the side and top facilitates maintenance from the front, improving after-sales convenience.
[0009] Furthermore, the heat dissipation module includes an exhaust fan located at the top of the refrigerator. The outer casing has an air inlet corresponding to the air inlet of the exhaust fan. The air outlet of the exhaust fan is connected to the air inlet of the heat dissipation duct. The air outlet of the heat dissipation duct extends through the bottom of the refrigerator to form an air outlet. The refrigeration module is a semiconductor module, with its cold end connected to the side wall of the inner liner and its hot end located on the heat dissipation duct. In this design, when the exhaust fan is working, it draws in cooler air from the upper part of the refrigerator from the air inlet at the top of the refrigerator, and sends it into the duct through the air inlet of the heat dissipation duct. When the low-temperature airflow passes through the hot end of the semiconductor module, a larger temperature difference is created, effectively carrying away the heat generated. The resulting hot air flows downwards along the heat dissipation duct and is finally discharged from the air outlet extending through the bottom of the refrigerator to the outside of the refrigerator. This process not only achieves physical isolation between the heat dissipation path and the storage space, but also significantly improves heat dissipation efficiency by utilizing the low-temperature air at the top and a clearly defined downward exhaust path, effectively preventing hot air from circulating and accumulating inside the cabinet. Furthermore, the heat dissipation duct includes a first channel arranged horizontally at the top and a second channel arranged vertically on the side. The first channel is connected to the air inlet of the exhaust fan, and the bottom of the second channel leads to the air outlet.
[0010] Furthermore, the space between the inner liner, the outer casing, and the heat dissipation duct is filled with thermal insulation material, thermally isolating the refrigerated space of the inner liner from the heat dissipation duct. This solution achieves a triple thermal insulation effect: firstly, it prevents the cold air in the inner liner from dissipating outward, ensuring refrigeration efficiency; secondly, it blocks the transfer of high temperature from the heat dissipation duct to the refrigerated space, avoiding cold air loss; and thirdly, it effectively prevents heat from the heat dissipation duct from the outer casing to the interior of the cabinet, thereby maintaining a normal or low temperature environment inside the storage cabinet. This design ensures that the exhaust fan can always draw in cooler air from the upper part of the cabinet, maintaining the efficient operation of the heat dissipation system, while significantly improving the overall energy efficiency and temperature control stability of the system.
[0011] Furthermore, the semiconductor module includes a cooling chip and a heat sink; the cold end of the cooling chip is connected to the inner cavity of the inner liner through a cooling block, and its hot end is thermally connected to the heat sink; the heat sink is located inside the heat dissipation duct.
[0012] Furthermore, it also includes a drip tray; a drain outlet is provided at the bottom of the inner liner; the drip tray is located below the inner liner and the heat dissipation duct to collect condensate dripping from the drain outlet; the drip tray is at least partially located on the heat dissipation duct. This solution achieves automatic collection and treatment of condensate by setting a drain outlet at the bottom of the inner liner and a drip tray below the inner liner and the heat dissipation duct. The drip tray is at least partially located at the heat dissipation duct, allowing it to receive waste heat airflow discharged from the heat dissipation duct. When condensate forms on the outer wall of the refrigerator's inner liner due to temperature difference, water droplets collect in the drip tray through the drain outlet, and the condensate is continuously evaporated using the flowing waste heat. This design achieves the recycling of internal system resources, automatically solving the problem of condensate accumulation, avoiding the hassle of manual cleaning, and generating no additional energy consumption, demonstrating the system's high integration and intelligence.
[0013] Furthermore, it also includes a module housing, which is generally L-shaped with a vertical flip, and the heat dissipation air duct is formed on its inner side.
[0014] Furthermore, it also includes a storage basket, which is arranged side-by-side with the refrigerator on the lifting frame. This design, by arranging the storage basket and refrigerator side-by-side on the lifting frame, creates a compact and functionally rational overall layout. This design not only makes the structure simple and reasonable but also makes full use of the cabinet width rather than its height, effectively saving vertical space and making the overall layout more compact and efficient.
[0015] Furthermore, the lifting frame includes a supporting base plate, and the supporting base plate is provided with heat dissipation holes corresponding to the air outlet position of the heat dissipation duct.
[0016] Another objective of this utility model is to provide a storage cabinet, including a cabinet body and a lift-up basket as described above, wherein the lift-up basket is disposed on the cabinet body. Attached Figure Description

It is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0028] See Figure 1-6 This utility model discloses a side-mounted refrigerated lift-up basket 1, including a lift-up frame 10, a refrigerator box 2, and a heat dissipation system 3. The refrigerator box 2 is disposed inside the lift-up frame 10. The refrigerator box 2 includes an inner liner 21 and an outer casing 22 covering the outer side of the inner liner 21. The heat dissipation system 3 includes a refrigeration module 4, a heat dissipation module 5, and a heat dissipation duct 6. The refrigeration module 4 is disposed between the outer casing 22 and the inner liner 21, and is equipped with a refrigeration end and a heat dissipation end. Its refrigeration end is thermally connected to the side outer wall of the inner liner 21. The heat dissipation module 5 is located above the refrigeration module 4. The heat dissipation duct 6 is located between the outer casing 22 and the inner liner 21. Its air inlet is located at the upper part of the refrigerator box 2, and its air outlet is located at the lower part of the refrigerator box 2. The heat dissipation end of the refrigeration module 4 and the heat dissipation module 5 are located on the heat dissipation duct.
[0029] In one embodiment, the heat dissipation module 5 includes an exhaust fan located at the top of the refrigerator 2. The outer casing 22 has an air inlet 221 corresponding to the air inlet of the exhaust fan. The air outlet of the exhaust fan is connected to the air inlet of the heat dissipation duct. The air outlet of the heat dissipation duct penetrates the bottom of the refrigerator 2 to form an air outlet 222. The refrigeration module 4 is a semiconductor module, with its cold end connected to the side wall of the inner liner 21 and its hot end located on the heat dissipation duct. In this solution, when the exhaust fan is working, it draws in cooler air from the upper part of the refrigerator from the air inlet 221 located at the top of the refrigerator 2, and sends it into the duct through the air inlet of the heat dissipation duct. When the low-temperature airflow passes through the hot end of the semiconductor module, it can create a larger temperature difference, thereby efficiently carrying away the heat generated by the module. After forming hot air, it flows downwards along the heat dissipation duct and is finally discharged to the outside of the refrigerator from the air outlet 222 penetrating the bottom of the refrigerator 2. This process not only achieves physical isolation between the heat dissipation path and the storage space, but also significantly improves heat dissipation efficiency by utilizing the low-temperature air at the top and a clear downward exhaust path, effectively preventing hot air from circulating and accumulating inside the cabinet. Furthermore, the heat dissipation duct includes a first channel 61 arranged horizontally at the top and a second channel 62 arranged vertically on the side. The first channel 61 is connected to the air inlet of the exhaust fan, and the bottom of the second channel 62 leads to the air outlet 222.
[0030] In one embodiment, the space between the inner liner 21, the outer casing 22, and the heat dissipation duct 6 is filled with thermal insulation material (not shown in the figure), which thermally isolates the refrigerated space of the inner liner 21 from the heat dissipation duct 6. This solution achieves a triple thermal insulation effect: firstly, it prevents the cold air in the inner liner 21 from dissipating outward, ensuring refrigeration efficiency; secondly, it blocks the transfer of high temperature in the heat dissipation duct 6 to the refrigerated space, avoiding cold air loss; and thirdly, it effectively prevents the heat from the heat dissipation duct from dissipating into the cabinet through the outer casing 22, thereby maintaining a normal or low temperature environment inside the storage cabinet 9. This design ensures that the exhaust fan can always draw in cooler air from the upper part of the cabinet, maintaining the efficient operation of the heat dissipation system 3, while significantly improving the overall energy efficiency and temperature control stability of the system.
[0031] In one embodiment, the semiconductor module includes a cooling chip 41 and a heat sink 42; the cold end of the cooling chip 41 is connected to the inner cavity of the inner liner 21 through a cooling block 211, and its hot end is thermally connected to the heat sink 42; the heat sink 42 is located inside the heat dissipation duct.
[0032] In one embodiment, a drip tray 8 is also included; a drain outlet 212 is provided at the bottom of the inner liner 21; the drip tray 8 is located below the inner liner 21 and the heat dissipation duct, and is used to collect condensate dripping from the drain outlet 212; the drip tray 8 is at least partially located on the heat dissipation duct. This solution achieves automatic collection and treatment of condensate by providing a drain outlet 212 at the bottom of the inner liner 21 and a drip tray 8 below the inner liner 21 and the heat dissipation duct. The drip tray 8 is at least partially located at the heat dissipation duct, allowing it to receive waste heat airflow discharged from the heat dissipation duct. When condensate forms on the outer wall of the inner liner 21 of the refrigerator 2 due to temperature difference, water droplets are collected in the drip tray 8 through the drain outlet 212, and the condensate is continuously evaporated using the flowing waste heat. This design realizes the recycling of internal resources of the system, automatically solves the problem of condensate accumulation, avoids the trouble of manual cleaning, and does not generate additional energy consumption, reflecting the high integration and intelligence of the system.
[0033] In one embodiment, the system further includes a module housing 7, which is generally L-shaped with a vertical flip and the heat dissipation duct is formed on its inner side.
[0034] In one embodiment, a storage basket 13 is also included, which is arranged side-by-side with the refrigerator 2 on the lifting frame 10. This design, by arranging the storage basket 13 and the refrigerator 2 side-by-side on the lifting frame 10, creates a compact and functionally rational overall layout. This design not only makes the structure simple and reasonable but also makes full use of the cabinet width rather than its height, effectively saving vertical space and making the overall layout more compact and efficient.
[0035] In one embodiment, the lifting frame 10 includes a supporting base plate 11, and the supporting base plate 11 is provided with heat dissipation holes 12 at the position corresponding to the air outlet 222 of the heat dissipation duct.
[0036] In one embodiment, a spring power cable 15 is provided between the lifting frame 10 and the refrigerator 2. The spring power cable 15 is led out from the bottom of the upper frame, and the bottom is fixed to the bottom plate of the lifting basket 1 by a wire clamp iron plate. The other end is connected to the refrigerator 2. Its elasticity ensures that the basket provides a continuous and stable power supply to the refrigerator 2 during the lifting process.
[0037] This utility model provides a side-mounted refrigerated lift-up basket 1. Its technical principle lies in the following: by laterally integrating the refrigeration module 4 between the inner liner 21 and the outer casing 22 of the refrigerator 2, the refrigeration end directly conducts heat with the side wall of the inner liner 21 to achieve refrigeration. Simultaneously, the heat dissipation module 5 located above the refrigeration module 4 drives airflow along the top-to-bottom heat dissipation duct 6 formed between the inner liner 21 and the outer casing 22. After absorbing heat at the heat dissipation end of the refrigeration module 4, the hot air is finally discharged directly to the outside of the storage cabinet 9 from the air outlet at the bottom of the refrigerator 2. This solution achieves three core effects: First, the lateral integration layout greatly optimizes the utilization of depth space, making the product more compatible with standard cabinets; second, the clearly defined forced heat dissipation duct 6 leading to the outside of the cabinet effectively avoids heat accumulation inside the cabinet, significantly improving heat dissipation efficiency and system stability; third, the module concentration on the side and top facilitates maintenance from the front, improving after-sales convenience.
