[0001] This utility model relates to the field of display cabinet technology, and in particular to air-cooled display cabinets and their high-efficiency cooling systems. Background Technology

[0002] Display cases are widely used in shopping malls and supermarkets to display and preserve food and beverages. Among them, air-cooled display cases use an air-cooling system to cool the inside of the case to maintain the freshness and display effect of the goods. However, existing air-cooled display cases still have certain shortcomings in terms of cooling efficiency, energy consumption and temperature uniformity. Therefore, air-cooled display cases and their high-efficiency cooling systems are needed.

[0003] A search revealed Chinese Patent Publication No. CN204467581U, which discloses a space-saving, air-cooled display cabinet comprising an outer cabinet and an inner cabinet within the outer cabinet. The outer cabinet has doors, and the inner cabinet contains several display shelves. Several slots are correspondingly provided on the side walls of the inner cabinet, with the ends of each display shelf located within these slots. This utility model provides a space-saving, air-cooled display cabinet. Its technical advantages include: the slots on the side walls of the inner cabinet for fixing the display shelves increase the internal space of the display cabinet, reducing waste; and the elimination of support frames reduces processing costs. However, this device uses a single fan and refrigeration system, circulating cold air to all corners of the cabinet. While this method achieves basic cooling, its cooling efficiency is low, energy consumption is high, and the uneven temperature distribution within the cabinet can negatively impact the preservation of goods. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an air-cooled display cabinet and its high-efficiency cooling system, aiming to improve the problems of the existing technology where the device uses a single fan and refrigeration system, which circulates cold air to all corners of the cabinet through the fan, resulting in low cooling efficiency, high energy consumption, and uneven temperature distribution inside the cabinet, which can easily affect the preservation of goods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-cooled display cabinet and its high-efficiency cooling system, comprising a cabinet body, mounting plates fixedly connected at equal intervals on the left and right sides of the inner wall of the cabinet body, a horizontal plate fixedly connected to the middle of the outer wall of two mounting plates, multiple shelf panels provided on the left and right sides of the outer wall of two mounting plates, partitions fixedly connected to the left and right sides of the inner wall of the mounting plates, multiple air intake fans fixedly connected to the bottom left and right sides of the inner wall of the cabinet body, a cooler connected to the left side of the outer wall of the multiple air intake fans, a vertical plate fixedly connected to the top of the multiple coolers, the top of the vertical plate fixedly connected to the top of the inner wall of the cabinet body, multiple air inlets opened on the left and right sides of the top of the inner wall of the cabinet body, an intake fan fixedly connected to the inner wall of the multiple air inlets, multiple air outlets opened on the front side of the outer wall of the cabinet body, a rear baffle threadedly connected to the rear side of the outer wall of the cabinet body, and a disassembly mechanism provided at both ends of the multiple shelf panels.

[0006] The above technical solution divides the cabinet into multiple areas using mounting plates and partitions. The top of the cabinet is hollow, so the uprights separate the cabinet into exhaust and intake channels. The intake fan draws outside air into the cabinet through the intake vent. The air flows inside the cabinet and is guided into the suction fan. After being drawn in, the air is cooled by the air cooler connected to the left side of the suction fan's outer wall, reducing its temperature. The cooled air is then expelled from the cooler and rises inside the cabinet, forming a circulating airflow. It is then discharged from the cabinet through multiple vents on the front side of the outer wall. As the air rises, it passes through the shelf and is eventually drawn in by the intake fan, thus completing a full air cooling cycle.

[0007] As a further description of the above technical solution:

[0008] Each of the disassembly mechanisms includes multiple sliding grooves and multiple locking blocks. The sliding grooves are respectively formed on the left and right sides of the outer wall of the shelf. The locking blocks are slidably connected to the inner walls of the sliding grooves. Multiple slots are formed on the left and right sides of the outer walls of the mounting plates. The locking blocks are respectively engaged with the corresponding slots. A connecting rod is fixedly connected to an adjacent side of each locking block. The other end of each connecting rod passes through the shelf. A spring is provided on the outer wall of the connecting rod. The opposite ends of the multiple springs are fixedly connected to the locking blocks. The other ends of the multiple springs are fixedly connected to the sliding grooves. A connecting plate is fixedly connected to the opposite ends of the multiple connecting rods.

[0009] The above technical solution involves locking blocks and slots on the left and right sides of the outer wall of the mounting plate. The position of the locking blocks is fixed by spring compression. When the mounting plate needs to be removed, the connecting plate is pulled, which drives the connecting rod to move outward and compresses the spring into the slide groove, thus disengaging it from the slot and removing the mounting plate from the mounting plate.

[0010] As a further description of the above technical solution:

[0011] The cabinet has support frames fixedly connected to the top left and right sides of the outer wall, and a display screen is fixedly connected to the front end of the two support frames.

[0012] Through the above technical solution: the support frame provides stable support for the display screen, which can be used to display the temperature and humidity parameters inside the cabinet.

[0013] As a further description of the above technical solution:

[0014] A hook is provided on the middle right side of the outer wall of the cabinet, and a screw is threaded to the left side of the outer wall of the hook. The hook is threaded to the cabinet through the screw.

[0015] Through the above technical solution, the main function of the hook is to provide users with a place to hang items. The hook is connected to the cabinet by screws, which is both firm and easy to install and remove.

[0016] As a further description of the above technical solution:

[0017] The bottom of the cabinet is fixedly connected to casters on all four sides, and each caster is equipped with a locking plate on its top.

[0018] Through the above technical solution: the function of the movable wheel is to enable the air-cooled display cabinet to move easily. Pressing down the locking plate and making contact with the movable wheel generates friction, thereby preventing the movable wheel from rolling and locking the display cabinet.

[0019] As a further description of the above technical solution:

[0020] Multiple glass panels are slidably connected to the top front side of the outer wall of the horizontal plate. The top of each glass panel is slidably connected to the cabinet body, and a pull handle is fixedly connected to the front side of the outer wall of each glass panel.

[0021] Through the above technical solution: the glass plate prevents air from flowing out of the cabinet, while also preventing outside air and impurities from entering the cabinet, thereby improving air cooling efficiency, reducing energy consumption, and making it convenient for users to operate the glass plate by pulling the handle.

[0022] As a further description of the above technical solution:

[0023] A second glass plate is slidably connected to the front end of the horizontal plate, and the front end of the second glass plate is slidably connected to the cabinet body. A hidden handle is rotatably connected to the inner wall of the second glass plate.

[0024] Through the above technical solution: the main function of the second glass panel is to protect and display the items placed in front of the horizontal panel. At the same time, it can also form a relatively enclosed space together with the first glass panel to improve the display effect and safety of the items. The hidden handle makes it convenient for users to operate the second glass panel.

[0025] As a further description of the above technical solution:

[0026] A controller is fixedly connected to the top right side of the outer wall of the cabinet. The controller is electrically connected to the cooler, the intake fan, and the air intake fan.

[0027] Through the above technical solution, the controller can simultaneously control multiple components and automatically adjust the temperature of different areas, giving the display case a certain degree of intelligent control function.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the cabinet is divided into multiple areas by the mounting plate and partition. Each area is equipped with an intake fan, an exhaust fan and a cooler, so that it can be controlled according to the different temperature requirements of each area, thereby reducing energy consumption and achieving precise control. The intake fan draws outside air into the cabinet. The air flows inside the cabinet and is guided into the exhaust fan. After being cooled by the cooler, it is discharged from the air outlet to achieve air cooling circulation.

[0030] 2. In this utility model, the locking blocks and slots on the left and right sides of the outer wall of the installation plate engage with each other. The locking blocks are fixed in position by spring compression. When the installation plate needs to be removed, the connecting plate is pulled, which drives the connecting rod to move outward and compresses the spring, causing the locking blocks to disengage from the slots and enter the slide groove. At this time, the installation plate can be removed from the installation plate, which facilitates cleaning and maintenance of the installation plate and improves the practicality of the device.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an air-cooled display cabinet and its high-efficiency cooling system, including a cabinet body 1. The cabinet body 1 serves as the main structure of the entire air-cooled display cabinet. The top of the cabinet body 1 is hollow to facilitate air circulation. Mounting plates 3 are fixedly connected at equal intervals on both the left and right sides of the inner wall of the cabinet body 1. The mounting plates 3 provide a foundation for the installation and support of subsequent components. A horizontal plate 5 is fixedly connected to the middle of the outer wall of the two mounting plates 3. The horizontal plate 5 divides the cabinet body 1 into upper and lower areas for storing different types of products. Multiple shelf panels 4 are provided on both the left and right sides of the outer wall of the two mounting plates 3. The shelf panels 4 provide space for displaying items, making it convenient for users to display various commodities, cultural relics, or other items. The displayed items are mounted on the inner left and right sides of the mounting plate 3, with partitions 6 fixedly connected. These partitions 6 divide the space inside the cabinet 1, for example, to prevent items from interfering with each other or to define different temperature zones. Multiple air intake fans 8 are fixedly connected to the bottom left and right sides of the inner wall of the cabinet 1. A cooler 7 is connected to the left side of the outer wall of each air intake fan 8. The main function of the air intake fans 8 is to draw air from inside the cabinet 1 towards the cooler 7, allowing the air to fully exchange heat with the evaporator in the cooler 7, thereby cooling the air inside the cabinet 1. A vertical plate 9 is fixedly connected to the top of each cooler 7, and the top of the vertical plate 9 is fixedly connected to the top of the inner wall of the cabinet 1. The upright plate 9 divides the internal airflow channel of the cabinet 1 into two parts for air supply and intake. Multiple air inlets 10 are provided on the top left and right sides of the inner wall of the cabinet 1. Air intake fans 11 are fixedly connected to the inner walls of each air inlet 10. The main function of the air intake fans 11 is to draw outside air into the cabinet 1 through the air inlets 10, providing an air source for the cooling circulation inside the cabinet 1. Multiple air outlets 12 are provided on the front side of the outer wall of the cabinet 1. After the cooling circulation, the air is discharged through the air outlets 12, completing one air cooling cycle. A rear baffle 13 is threaded onto the rear side of the outer wall of the cabinet 1. When maintenance or repair is required, maintenance personnel can use tools to unscrew the rear baffle. Remove the screws on panel 13, remove the back panel 13, and then inspect and repair the internal components of cabinet 1. Both ends of multiple shelf panels 4 are equipped with disassembly mechanisms 2. Multiple glass panels 20 are slidably connected to the top front side of the outer wall of the horizontal panel 5. The main function of the glass panels 20 is to protect and display the items placed on the horizontal panel 5, and also to prevent dust, debris and other objects from entering the interior of cabinet 1. The tops of multiple glass panels 20 are slidably connected to cabinet 1. Pull handles 21 are fixedly connected to the front side of the outer wall of multiple glass panels 20. When it is necessary to place or take out items, the user can hold the pull handles 21 and slide the glass panels 20 left and right to open the corresponding area.A second glass plate 22 is slidably connected to the front end of the horizontal plate 5. The front end of the second glass plate 22 is slidably connected to the cabinet body 1. The main function of the second glass plate 22 is to protect and display items placed in front of the horizontal plate 5. It can also form a relatively enclosed space with the first glass plate 20 to improve the display effect and safety of the items. A hidden handle 23 is rotatably connected to the inner wall of the second glass plate 22. The hidden handle 23 makes it convenient for users to operate the second glass plate 22 to place or take out items. A controller 24 is fixedly connected to the top right side of the outer wall of the cabinet body 1. The controller 24 is electrically connected to the cooler 7, the exhaust fan 8 and the intake fan 11 respectively. The controller 24 controls different coolers 7 and exhaust fans 8 to control the temperature in different areas.

[0041] Specifically, because the mounting plate 3 and partition 6 divide the cabinet 1 into multiple areas, and the top of the cabinet 1 is a hollow structure, the upright plate 9 separates the interior of the cabinet 1 into an exhaust channel and an intake channel. When the display cabinet is in operation, multiple intake fans 11 located on the top left and right sides of the inner wall of the cabinet 1 start to operate. The intake fans 11 draw outside air into the cabinet 1 through the air inlet 10. The air flows inside the cabinet 1. Due to the action of the suction fan 8, the air is guided into the suction fan 8. After being drawn in by the suction fan 8, the air is cooled by the air cooler 7 connected to the left side of the outer wall of the suction fan 8, which lowers the air temperature. The cooled air is discharged from the cooler 7 and rises inside the cabinet 1, forming a circulating airflow. Then, it is discharged from the cabinet 1 through multiple air outlets 12 opened on the front side of the outer wall of the cabinet 1. During the rising process, the air passes through the shelf 4 and is finally drawn into the cabinet. The air fan 11 draws in air, completing a full air cooling cycle, thus allowing for individual control of different areas and reducing energy consumption. Glass plate 20 prevents high-temperature gases from entering the area above the horizontal plate 5. When the position of glass plate 20 needs to be adjusted, the user can easily move it left and right along its sliding track by holding the pull handle 21, thereby achieving operation control of the corresponding area. Glass plate 22 prevents high-temperature gases from entering the area below the horizontal plate 5. The hidden handle 23 provides a convenient way for the user to operate glass plate 22 and saves floor space. Through the controller 24, the user can centrally control the key components of the cooling system of the air-cooled display case, enabling the operation of the air-cooled display case to better adapt to different display needs and environmental conditions, and achieve intelligent regulation.

[0042] Reference Figure 2 , Figure 5 and Figure 6The multiple disassembly mechanisms 2 each include multiple sliding grooves 201 and multiple locking blocks 202. The sliding grooves 201 provide sliding tracks for the locking blocks 202, allowing the locking blocks 202 to move during the connection process between the shelf 4 and the mounting plate 3, achieving the functions of engagement and disengagement. The multiple sliding grooves 201 are respectively opened on the left and right sides of the outer wall of the shelf 4, and the locking blocks 202 are slidably connected to the inner wall of the sliding grooves 201. The multiple mounting plates 3 have multiple locking slots 203 on the left and right sides of their outer walls, and the multiple locking blocks 202 engage with the corresponding multiple locking slots 203. The engagement of the locking blocks 202 with the locking slots 203 is the key to fixing the shelf 4 to the mounting plate 3. Through the engagement structure, it is ensured that the shelf 4 will not easily loosen or fall off during use. Each adjacent side of the multiple locking blocks 202 is fixedly connected with a connecting rod. 204, the connecting rod 204 serves to connect the locking block 202. The other end of the multiple connecting rods 204 all penetrates the shelf 4. The outer wall of the connecting rod 204 is provided with a spring 205. The far ends of the multiple springs 205 are fixedly connected to the locking block 202. The other ends of the multiple springs 205 are fixedly connected to the slide groove 201. The springs 205 provide elastic force to the locking block 202, so that the locking block 202 can automatically lock into the slot 203 during installation and can be easily pulled back into the slide groove 201 during disassembly. The far ends of the multiple connecting rods 204 are fixedly connected to a connecting plate 206. The connecting plate 206 provides a convenient operating part for the user. By pulling the connecting plate 206, the multiple connecting rods 204 and the locking block 202 can be moved at the same time to realize the disassembly of the shelf 4.

[0043] Specifically, when installing the shelf 4, align the sliding grooves 201 at both ends of the shelf 4 with the corresponding slots 203 on the left and right sides of the outer wall of the mounting plate 3, and then push the shelf 4 towards the slots 203. The locking block 202 slides within the sliding groove 201. Since the spring 205 is initially in its natural state, when the locking block 202 contacts the mounting plate 3, under the pressure of the mounting plate 3, the locking block 202 will be pressed into the sliding groove 201. At this time, the spring 205 compresses, and when the locking block 202 reaches the position of the slot 203... After placement, under the elastic force of spring 205, the locking block 202 will spring into the locking groove 203, thereby fixing the shelf 4 onto the mounting plate 3, completing the installation of the shelf 4; when it is necessary to remove the shelf 4, by pulling the connecting plate 206, the connecting plate 206 drives the connecting rod 204 to move outward and compress the spring 205, so that the locking block 202 enters the slide groove 201 and disengages from the locking groove 203. At this time, the shelf 4 can be removed from the mounting plate 3, making it convenient to clean and maintain the shelf 4.

[0044] Reference Figure 1 , Figure 2 and Figure 3Support frames 14 are fixedly connected to the top left and right sides of the outer wall of cabinet 1. A display screen 15 is fixedly connected to the front end of each support frame 14. The function of the support frames 14 is to provide stable support for the display screen 15, ensuring that the display screen 15 can be installed on the top of cabinet 1 and will not shake or fall during use. The display screen 15 can be used to display the temperature and humidity parameters inside cabinet 1. A hook 16 is provided in the middle of the right side of the outer wall of cabinet 1. A screw 17 is threadedly connected to the left side of the outer wall of hook 16. Hook 16 is threaded to cabinet 1 via screw 17. The central threaded connection is both sturdy and easy to install and disassemble. When the hook 16 is needed, the user hangs the item on the hook 16. The hook 16 can bear a certain weight to ensure that the item will not fall. The bottom of the cabinet 1 is fixedly connected with casters 18 around the perimeter. Each caster 18 is equipped with a locking plate 19 on its top. The casters 18 allow the display cabinet to move easily on the ground. When the display cabinet is moved to the desired position, the user presses down the locking plate 19 to make the locking plate 19 contact the caster 18 and generate friction, thereby preventing the caster 18 from rolling and locking the display cabinet.

[0045] Specifically, the support frame 14 allows the display screen 15 to be stably positioned above the cabinet 1. The display screen 15 is used to display the current temperature setting, actual temperature value, and working status of the air-cooled display cabinet 7. The hook 16 is used to hang price tags and promotional posters. The hook 16 is connected with screws 17 so that it can be firmly installed on the cabinet 1 and is also easy to disassemble or replace when needed. The casters 18 facilitate movement in different places. When it is necessary to fix the position of the display cabinet to prevent it from moving accidentally, it can be locked by operating the locking plate 19.

[0046] Working principle: Before using the device, the intake fan 11 starts operating, drawing outside air into the cabinet 1 through the air inlet 10. The air flows inside the cabinet 1, and due to the action of the suction fan 8, the air is guided into the suction fan 8. After being drawn in by the suction fan 8, the air is cooled by the cooler 7 connected to the left side of the outer wall of the suction fan 8, lowering its temperature. The cooled air is then discharged from the cooler 7 and rises inside the cabinet 1, forming a circulating airflow. Subsequently, it is discharged from the cabinet 1 through multiple air outlets 12 on the front side of the outer wall of the cabinet 1. During its ascent, the air passes through the shelf 4 and is finally drawn in by the intake fan 11, thus completing a full air cooling cycle. This allows for individual control of different areas, reducing energy consumption. The cabinet 1 is divided into multiple areas by partitions 3 and 6. Each area is equipped with an intake fan 11, an exhaust fan 8, and a cooler 7, which can be controlled according to the different temperature requirements of each area, thereby reducing energy consumption and achieving precise control. Furthermore, the mounting plate 4 is secured by the locking blocks 202 and slots 203 on the left and right sides of its outer wall. The locking blocks 202 are fixed in position by springs 205. When the mounting plate 4 needs to be removed, the connecting plate 206 is pulled, which moves the connecting rod 204 outward and compresses the spring 205, causing the locking blocks 202 to enter the slide groove 201 and disengage from the slot 203. At this time, the mounting plate 4 can be removed from the mounting plate 3, which facilitates cleaning and maintenance of the mounting plate 4 and improves the practicality of the device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
