Description

Technical Field

[0001] The present application relates to the technical field of refrigerator manufacturing, and in particular to an open refrigerator with an upper exhaust center. Background Art

[0002] As a key terminal equipment in the food cold chain, the refrigerated central open cabinet plays a vital role in modern supermarkets, convenience stores and catering industries. This equipment can not only provide a suitable refrigerated temperature for food to ensure its quality and safety, but also beautify the shopping environment through an open display method and stimulate consumers' desire to buy; the design of the central open cabinet integrates air curtain technology. Through the aerodynamically optimized multi-stage extrusion air curtain, it effectively prevents the entry of external hot and humid air, and at the same time transfers the cold air on the evaporator to the cabinet, taking away the heat of the food to achieve a cooling effect. The air curtain can significantly reduce the heat exchange inside and outside the cabinet, and the circular honeycomb net can form a smooth and uniform air curtain, further reducing the system's cold loss. In order to ensure the best performance of the air curtain. With the continuous advancement of technology and the continuous development of the market, the performance of the refrigerated central open cabinet will be further improved, providing more efficient and reliable solutions for the food cold chain industry.

[0003] The application of central open cabinets for refrigeration in large shopping malls has become more and more common, and in order to meet the wide range of refrigeration needs, multiple devices are often required. However, when these refrigeration devices are in operation, their refrigeration units will inevitably generate a lot of heat. Faced with such a practical situation, how to scientifically and rationally utilize the internal space of the shopping mall, while being able to quickly and effectively clean and discharge the heat generated by the refrigeration unit at the bottom, has become a key technical problem that technicians in this field need to solve urgently. Summary of the invention

[0004] The device provides an open cabinet with an upper exhaust center, and the specific implementation is as follows:

[0005] An open cabinet with upper exhaust center, comprising:

[0006] A refrigerated cabinet consisting of an upper cabinet and a lower cabinet, wherein the lower cabinet has a built-in compressor and a condenser for refrigeration, and the evaporator is built into the cold air circulation cavity of the upper cabinet, and the compressor, condenser and evaporator are connected by pipelines;

[0007] The exhaust assembly is arranged at the back of the refrigerator, and includes a mounting frame, the two sides of which are vertically divided into two parallel exhaust ducts by partitions, and a fan is installed in the exhaust duct. The air inlet of the mounting frame is connected to the lower cabinet, and the air outlet is opened at the top of the mounting frame. The operating heat of the refrigeration unit in the lower cabinet is discharged to the outside through the top of the refrigerator through the exhaust assembly.

[0008] Preferably, the cold air circulation cavity is configured as an upwardly open U-shaped structure, and the air supply fan and the evaporator are arranged at the bottom of the U-shaped structure.

[0009] Based on the above technical solution, the installation frame in the exhaust assembly is optimized to present a side-conducting structure, so that when the refrigerator is placed against the wall, the hot air of a single refrigerator can be quickly discharged upward and dissipated efficiently.

[0011] Preferably, a filter is installed on the top of the collector at the air outlet of the mounting frame.

[0012] Based on the above technical solution, the gas from both sides is combined into one in the second half of the flow path through the collector, and is centrally guided to the discharge port for unified discharge. The front half is separated by a partition to ensure that the fans on both sides can more efficiently extract the hot air in the lower cabinet. In order to further enhance the air circulation efficiency, the side of the lower cabinet is also equipped with an air inlet grille to ensure that fresh air can smoothly enter the lower cabinet, thereby improving the heat dissipation performance and operating efficiency of the entire system.

[0013] Preferably, a pair of refrigerators are provided, the mounting frame is plugged into the backs of the two refrigerators, and the ends of the two exhaust ducts in the mounting frame are respectively connected to the interiors of the two lower cabinets.

[0014] Preferably, a plurality of fans are evenly distributed along the length direction of the installation frame, and the installation angles of the fans are inclined downward.

[0015] Based on the above technical solution, two refrigerators are installed back to back through exhaust components, which not only greatly saves installation space and maximizes space utilization, but also ensures that the hot air generated by the refrigeration unit during operation can be discharged upward quickly and efficiently, thereby achieving excellent heat dissipation effect.

[0016] Preferably, a flap plate is rotatably provided at the top of the partition, and a driving motor is connected to the rotation center, and the length of the flap plate is not less than the distance between the top of the partition and the bottom of the collector.

[0017] Preferably, it also includes a controller and temperature sensors arranged in the exhaust ducts on both sides of the partition, the signal input end of the controller is electrically connected to the temperature sensor, and the signal output end of the controller is electrically connected to the drive motor.

[0018] Based on the above technical scheme, through the controller, temperature sensor and the flap plate controlled by the drive motor, the controller can make dynamic and intelligent adjustments according to the outlet air temperature information monitored in real time by the two refrigerators; the controller will flexibly adjust the inclination angle of the flap plate based on the data, and the angle change of the flap plate can correspond to different outlet air temperatures in real time, thereby accurately changing the size of the air outlet volume, and greatly promoting the rapid discharge and efficient heat dissipation of the heat inside the refrigerator, which not only optimizes the operating efficiency of the equipment, but also further improves the performance and stability of the overall system; different from the above scheme, the temperature sensor and controller can still be used to adjust the heat dissipation of the two central open cabinets, but the drive motor and the flap plate can be removed, the controller is electrically connected to the fan, and the air outlet volume is adjusted by controlling the fan power.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. The present invention installs two refrigerators back to back by arranging an exhaust assembly, which saves the space required for installation and also realizes the rapid upward discharge and heat dissipation of the hot air generated by the refrigeration unit;

[0035] The following is combined with Figure 1 -Attached Figure 6 This application is described in further detail.

[0036] The embodiment of the present application discloses an open cabinet with an upper exhaust center.

[0037] Example 1

[0038] Reference Figures 1 to 3 The present embodiment discloses a cabinet with an upper exhaust center opening, including a refrigerator 1 consisting of an upper cabinet 101 and a lower cabinet 102 and an exhaust assembly 2 arranged at the back of the refrigerator 1, the exhaust assembly 2 includes a mounting frame 204, the inner sides of which are vertically divided into two parallel exhaust ducts by a partition 203, and a fan 202 is installed in the exhaust duct, the air inlet of the mounting frame 204 is connected to the lower cabinet 102, and the air outlet of the mounting frame 204 is opened at the top of the mounting frame 204. In this structure, by installing the exhaust assembly 2, the refrigerator 1 is placed against the wall, so that the upward heat dissipation and exhaust of the lower cabinet 102 in a single refrigerator 1 can be achieved.

[0039] The exhaust component 2 discharges the operating heat of the refrigeration unit in the lower cabinet 102 to the outside through the top of the cold storage cabinet 1. A collector 205 is provided on the top of the mounting frame 204. The collector 205 vertically corresponds to the two exhaust ducts separated by the partition 203. In this structure, a lateral open gap is provided between the bottom of the collector 205 and the top of the partition 203. Through this gap, the overall structure is optimized without affecting the use effect.

[0040] The lower cabinet 102 has a built-in compressor 3 and a condenser 4 for refrigeration, and the evaporator 5 is built in the cold air circulation chamber 103 of the upper cabinet 101, and the compressor 3, condenser 4 and evaporator 5 are connected by pipelines. In this structure, the cold air circulation chamber 103 is configured as an upwardly open U-shaped structure, and the supply fan and the evaporator 5 are arranged at the bottom of the U-shaped structure.

[0041] Example 2

[0042] Reference Figures 1 to 5 Based on the above embodiment, the present embodiment further discloses a cabinet with an upper exhaust center opening, wherein a pair of refrigerators 1 are provided, and a mounting frame 204 is plugged into the backs of the two refrigerators 1, and ends of the two exhaust ducts in the mounting frame 204 are respectively connected to the interiors of the two lower cabinets 102. Although both sides of the top of the mounting frame 204 in the present structure are open, after being plugged into the two refrigerators 1, a structure that is only open upward is formed, thereby simplifying the overall structure while satisfying the use effect.

[0043] Example 3

[0044] Reference Figures 1 to 6 Based on Example 2, this embodiment further discloses a cabinet with an upper exhaust center open, which also includes a controller 7 and a temperature sensor 6 arranged in the exhaust duct on both sides of the partition 203. A flap plate 207 is rotatably provided at the top of the partition 203, and a drive motor 206 is connected to the rotation center. In this structure, the signal input end of the controller 7 is electrically connected to the temperature sensor 6, and its signal output end is electrically connected to the drive motor 206. The length of the flap plate 207 is not less than the distance between the top of the partition 203 and the bottom of the confluence cover 205. According to the actual operating status of the two refrigerators 1, the inclination angle of the flap plate 207 is used to select the size of the air volume of the upward exhaust on both sides. The larger the refrigeration power of the refrigerator 1, the more heat it produces, and thus it needs a larger air volume. The exhaust temperature is detected by the controller 7 and the temperature sensor 6. If the exhaust temperature is high, it is determined to produce more heat.

[0045] The specific implementation process is as follows: under the action of the compressor 3 and the condenser 4, the evaporator 5 produces a cooling effect; the exhaust fan at the evaporator 5 position is started, and the air in the upper cabinet 101 flows along the cold air circulation cavity 103, and is cooled down into cold air when passing through the evaporator 5, so that the food in the upper cabinet 101 can be refrigerated and fresh; during the operation of the compressor 3 and the condenser 4, the two generate a large amount of heat in the lower cabinet 102;

[0046] In order to dissipate the heat of the lower cabinet 102 in time, the fans 202 on both sides are started, and the heat in the lower cabinets 102 on both sides is sucked into the exhaust duct; during this period, the temperature sensors 6 on both sides perform real-time temperature acquisition, and the controller 7 dynamically acts on the drive motor 206 to adjust the posture of the flap 207 according to the temperature; the higher the temperature acquisition, the further the flap 207 moves away from that side to increase its exhaust volume; when the temperature acquisition data on both sides are consistent, the flap 207 is in a vertical posture.

[0047] Example 4

[0048] Reference Figures 1 to 4 Based on the above embodiments, the present embodiment further discloses an open cabinet with an upper exhaust center, wherein a plurality of fans 202 are evenly distributed along the length direction of the mounting frame 204, and the installation angle of the fans 202 is tilted downward, and a filter 201 is installed at the air outlet of the mounting frame 204 on the top of the collector 205. In the present structure, a direction-adjusting grille can be installed on the outside of the filter 201. By manually adjusting the inclination angle of the direction-adjusting grille, the upward outlet wind direction of the upper exhaust can be selected according to the actual site conditions.

[0049] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
