Description

Technical Field

[0001] This application relates to the field of island cabinet manufacturing technology, and in particular to an island cabinet with concealed top exhaust. Background Technology

[0002] Refrigerated island display cases, as a type of medium-sized refrigeration equipment, are typically placed in the center of modern commercial environments, especially in retail industries such as supermarkets, shopping malls, and convenience stores. They serve both as a display space for goods and as a way to divide space and optimize the shopping experience. Refrigerated island display cases utilize refrigeration technology to quickly lower and maintain a constant temperature inside the case. This helps extend the shelf life of goods and reduce spoilage. To reduce energy consumption, modern refrigerated island display cases typically employ energy-saving designs, such as using environmentally friendly refrigerants and optimizing the refrigeration system. The designs of refrigerated island display cases are becoming increasingly diverse to meet the needs of different businesses. They can be customized according to the type, size, and display requirements of goods, such as incorporating multi-layer shelves and glass doors.

[0003] Under long-term, high-intensity operation, the refrigeration system inside the island cabinet needs to work continuously to maintain a constant temperature inside the cabinet. The refrigeration system, especially key components such as the compressor, generates a lot of heat during operation. If this heat cannot be effectively dissipated, it will gradually accumulate at the bottom of the equipment, leading to a decrease in the efficiency of the refrigeration system. In order to maintain the temperature inside the cabinet, the compressor has to work harder, thus consuming more electricity. This not only increases operating costs but may also accelerate the wear and tear of the equipment and shorten its service life. Summary of the Invention

[0004] This device provides a concealed top-exhaust island cabinet, the specific implementation of which is as follows:

[0005] A concealed top-exhaust island cabinet includes:

[0006] The cabinet has a refrigeration generating chamber at the bottom, in which a refrigeration unit is installed. The cabinet also has a cold storage compartment with an opening at the top. The cold storage compartment is surrounded vertically by a cold air circulation channel, and the refrigeration unit operates on the evaporator within the cold air circulation channel.

[0007] The fan is located inside the refrigeration chamber, and the exhaust assembly is located at the back of the cabinet. The exhaust assembly is composed of a vertical partition plate, and a vertical upward exhaust channel is formed between the partition plate and the back of the cabinet. The exhaust channel is connected to the exhaust port of the fan. By embedding the fan inside the refrigeration chamber, the exhaust channel is installed at the back of the cabinet with an extremely narrow width.

[0008] Preferably, the exhaust assembly consists of an air inlet fixedly installed inside the refrigeration generating chamber and an isolation plate movable outside the refrigeration generating chamber, with the air inlet connected to the exhaust duct through a guide port.

[0009] Based on the above technical solutions, by setting an exhaust component in the cabinet structure, the heat generated by the bottom refrigeration unit is successfully and quickly discharged from the top of the cabinet, which greatly ensures that the refrigeration unit can maintain its long-term, high-efficiency operation, thereby ensuring the stability and reliability of the overall system. Furthermore, by embedding the fan in the refrigeration generation chamber, not only is the space occupied by the exhaust component in the cabinet significantly reduced, but the entire refrigeration system can also achieve efficient heat removal and discharge without the need to expand the original space of the cabinet, which not only optimizes the space but also improves the refrigeration efficiency.

[0010] Preferably, positioning blocks are provided at both the top and bottom of the guide port; barbs are provided at both ends of the isolation plate, and the isolation plate is laterally slidably connected to the positioning blocks through the barbs.

[0011] Based on the above technical solutions, by setting positioning blocks and using sliding isolation plates in conjunction with them, a heat dissipation channel structure that is easy to disassemble and maintain has been successfully constructed. This not only greatly improves the convenience of heat dissipation channel maintenance, allowing users to easily clean the heat dissipation channel, but also effectively ensures the efficient operation and long-term performance of the heat dissipation channel. This lateral sliding mechanism also simplifies the operation steps, reduces maintenance costs, and brings users a more efficient and flexible user experience.

[0012] Preferably, a filter screen is provided on the top barb of the isolation plate.

[0013] Preferably, it also includes a controller, a temperature sensor and a photoelectric sensor located in the exhaust duct; the signal input terminal of the controller is electrically connected to the temperature sensor and the photoelectric sensor, and its signal output terminal is electrically connected to the fan.

[0014] Preferably, both the temperature sensor and the photoelectric sensor are mounted on the positioning block by bolts.

[0015] Based on the above technical solutions, and addressing the heat dissipation needs of the island cabinet, temperature and photoelectric sensors are deployed inside the heat dissipation channel to achieve comprehensive and real-time monitoring of gas parameters within the channel. This allows for precise capture of changes in gas mass and temperature, providing reliable data support for subsequent fan power adjustments. Based on this real-time data, the system can intelligently adjust fan power, thereby achieving dynamic and precise control of the island cabinet's cooling airflow. When the temperature sensor detects a temperature rise within the heat dissipation channel, the system automatically increases fan power to enhance cooling airflow and ensure stable internal temperature. Conversely, when the photoelectric sensor detects a decrease in gas mass, the system adjusts fan power accordingly to optimize airflow and maintain the freshness of the air exhausted from the heat dissipation channel. To further enhance the intelligent heat dissipation performance of the island cabinet and ensure customer comfort, a light grating sensor or human body sensor can be added externally. This allows for precise detection of human activity around the island cabinet, enabling intelligent control of the cooling system. When the sensor detects no one near the island cabinet, the system automatically increases fan power to accelerate airflow within the cooling channel, achieving rapid and efficient heat dissipation.

[0016] Preferably, the end of the guide port is provided with an inclined guide plate, and the inclined guide plate is inclined upward.

[0017] Preferably, the refrigeration unit consists of an interconnected condenser and a compressor, with the condenser connected to the evaporator.

[0018] Based on the above technical solution, the inclined air guide plate has an obtuse-angled plate structure. One end of the inclined air guide plate is inserted into the bottom of the guide port to ensure a stable connection and positioning, while the other end extends upward in an inclined shape to form a smooth hot air guide channel. This allows the hot air to flow smoothly along the inclined direction of the inclined air guide plate, avoiding the stagnation and accumulation of hot air in the heat dissipation channel, thereby significantly improving the heat dissipation efficiency. At the same time, the obtuse-angled plate structure of the inclined air guide plate also enhances its structural strength and stability, ensuring its durability and reliability during long-term use.

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

[0020] 1. This utility model enables the heat from the bottom refrigeration unit to be quickly dissipated from the top by setting an exhaust component on the cabinet, ensuring the long-term and efficient operation of the refrigeration unit. Furthermore, by embedding the fan inside the refrigeration generating chamber, the area occupied by the exhaust component is reduced, thus achieving efficient heat removal from the refrigeration unit without additional expansion of the cabinet space.

[0021] 2. This utility model achieves quick disassembly and maintenance of the heat dissipation channel and convenient cleaning of the heat dissipation channel by setting a positioning block and an isolation plate that slides with it;

[0022] 3. This utility model has a simple structure. By setting temperature sensors and photoelectric sensors, it realizes the detection of gas parameters in the heat dissipation channel. By adjusting the fan power according to the gas mass and temperature, it realizes the dynamic adjustment of the heat dissipation wind speed. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail.

[0036] This application discloses a concealed top-exhaust island cabinet.

[0037] Example 1

[0038] Reference Figures 1 to 4 This embodiment discloses a concealed top-exhaust island cabinet, including a cabinet body 1 with a refrigeration generation chamber 103 at the bottom, a fan 3 inside the refrigeration generation chamber 103, and an exhaust assembly 2 at the back of the cabinet body 1. A refrigeration unit 4 is installed inside the refrigeration generation chamber 103, and a refrigerator compartment 101 with a top opening is also provided on the cabinet body 1. A cold air circulation channel 102 is vertically arranged around the outside of the refrigerator compartment 101, and the refrigeration unit 4 acts on the evaporator 5 in the cold air circulation channel 102. The refrigeration unit 4 is composed of a condenser 401 and a compressor 402 connected to each other. The condenser 401 is connected to the evaporator 5. In this structure, the exhaust assembly 2 is composed of a vertical isolation plate 203. A vertically upward exhaust channel is formed between the isolation plate 203 and the back of the cabinet body 1, and the exhaust channel is connected to the exhaust port of the fan 3. By embedding the fan 3 inside the refrigeration generation chamber 103, the exhaust channel is installed at the back of the cabinet body 1 with an extremely narrow width.

[0039] The exhaust assembly 2 consists of an air inlet seat 202 fixedly installed in the refrigeration generating chamber 103 and an isolation plate 203 movably installed outside the refrigeration generating chamber 103. The air inlet seat 202 is connected to the exhaust channel through a guide port 204. In this structure, the end of the guide port 204 is provided with an inclined guide plate 205, and the inclined guide plate 205 is inclined upward. The inclined guide plate 205 provides a guiding effect for the hot air discharged in the guide port 204, further improving the heat dissipation efficiency.

[0040] The specific implementation process is as follows: During the operation of the island cabinet, the long-term operation of the refrigeration unit 4 causes the temperature inside the refrigeration generation chamber 103 to rise; by turning on the fan 3, the hot air is exhausted upward through the air inlet seat 202, the guide port 204 and the heat dissipation channel, so that the temperature inside the refrigeration generation chamber 103 can be reduced.

[0041] Example 2

[0042] Reference Figures 1 to 5Based on the above embodiments, this embodiment also discloses a concealed top-exhaust island cabinet. Positioning blocks 6 are provided at both the top and bottom of the duct opening 204. Both ends of the isolation plate 203 are provided with barbs 2031 facing inward. The isolation plate 203 is laterally slidably connected to the positioning blocks 6 through the barbs 2031. A filter screen 201 is provided on the top barb 2031 of the isolation plate 203. In this structure, the isolation plate 203 can be disassembled and assembled by pushing and pulling the isolation plate 203 laterally, making the subsequent maintenance and cleaning of the internal heat dissipation channel more convenient.

[0043] Example 3

[0044] Reference Figures 1 to 6 Based on the above embodiments, this embodiment also discloses a concealed top-exhaust island cabinet, which further includes a controller 9, a temperature sensor 7 and a photoelectric sensor 8 disposed in the exhaust duct. The temperature sensor 7 and the photoelectric sensor 8 are both bolted to the positioning block 6. The signal input terminal of the controller 9 is electrically connected to the temperature sensor 7 and the photoelectric sensor 8, and its signal output terminal is electrically connected to the fan 3. In this structure, the power of the fan 3 is changed by the real-time detection of the temperature sensor 7 and the photoelectric sensor 8. When the temperature sensor 7 detects that the temperature is too high, the fan 3 increases its power and quickly exhausts air upward through the exhaust duct to dissipate heat. When the photoelectric sensor 8 detects that there are too many particles, the fan 3 reduces its power or shuts down to clean the impurities in the exhaust duct.
