Description

Technical Field

[0001] This invention relates to the field of display cabinet technology, and more specifically, to a novel refrigerated display cabinet with a transparent glass door and air duct. Background Technology

[0002] With societal progress and rising living standards, refrigeration equipment has become increasingly prevalent in daily life. Display cases, in particular, have become an indispensable part of retail spaces such as shopping malls and supermarkets, used to display and store various foods and beverages requiring refrigeration. In recent years, as consumers have increasingly pursued a higher quality of life, display cases have also gradually entered homes for storing alcoholic beverages and other soft drinks.

[0003] To meet consumers' demand for intuitive product display, transparent glass doors have become the mainstream choice for display cases. However, compared to traditional solid doors, glass doors have poorer thermal insulation. Furthermore, the frequent opening and closing of the cabinet doors by customers while shopping further exacerbates temperature fluctuations inside the display case, placing higher demands on the refrigeration system.

[0004] In traditional display case designs, the evaporator and evaporator fan are typically placed at the top of the cabinet. While this layout meets refrigeration requirements to some extent, it occupies valuable internal space and reduces the display case's load capacity. Furthermore, the top-mounted evaporator and fan also detract from the overall aesthetics of the display case. Summary of the Invention

[0005] The purpose of this invention is to provide a novel refrigerated display case with a transparent glass door and air duct, addressing the issue raised in the background section where, in traditional display case designs, the evaporator and evaporation fan are typically placed at the top of the cabinet. While this layout meets refrigeration requirements to some extent, it occupies valuable internal space, reducing the display case's capacity. Furthermore, the top-mounted evaporator and fan also negatively impact the overall aesthetics of the display case.

[0006] To achieve the above objectives, the present invention provides a novel refrigerated display cabinet with a transparent glass door and air duct, comprising a cabinet body, the cabinet body comprising an outer shell and an inner liner, an insulation layer disposed between the outer shell and the inner liner, and a circulating air duct disposed inside the inner liner, the circulating air duct comprising an air duct system and an air duct plate, the air duct plate dividing the interior of the inner liner into several vertical air ducts, the air duct system being installed on the back of the inner liner for forming circulating air inside the inner liner, the air duct system comprising an evaporator and a centrifugal fan, and an air duct cover plate being installed on one side of the evaporator and the centrifugal fan.

[0007] As a preferred embodiment of the present invention, a cabinet door is installed on the front of the cabinet, and a refrigeration system is installed at the bottom of the cabinet. The refrigeration system includes a lower front cover, and a condenser and a compressor are installed inside the lower front cover. The evaporator, condenser and compressor are connected by pipes to form a refrigeration circuit.

[0008] As a preferred embodiment of the present invention, an air guide is provided on the top of the air duct cover near the air inlet of the evaporator, and several air guide plates are installed at the air guide.

[0009] As a preferred embodiment of the present invention, the air outlet of the evaporator is located at the bottom, a fan cover is installed on the outside of the centrifugal fan, an air intake is provided on one side of the centrifugal fan, and an air exhaust is provided at the bottom of the centrifugal fan.

[0010] As a preferred embodiment of the present invention, the upper part of the fan cover is provided with an inclined surface, which guides the air outlet of the evaporator and directs the cold air to the air inlet where it is drawn in by the centrifugal fan.

[0011] As a preferred embodiment of the present invention, a wind baffle is installed at the lower part of the air intake.

[0012] As a preferred embodiment of the present invention, the air guide plates are arranged at equal intervals.

[0013] As a preferred embodiment of the present invention, a baffle plate is installed inside the fan cover to guide the intake cold air to the exhaust port for discharge.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This novel refrigerated display case with a transparent glass door utilizes air ducts to effectively maximize internal space and increase the display case's capacity. By mounting the evaporator and centrifugal fan at the back of the cabinet and dividing the interior into several vertical air ducts using an air duct panel, this invention avoids the space-consuming and aesthetically pleasing problems associated with traditional top-mounted designs. Furthermore, the invention employs a circulating air duct design, allowing cold air to circulate within the interior. This design not only improves refrigeration efficiency but also ensures temperature uniformity within the display case, better meeting refrigeration requirements. By incorporating air vents and guide plates at the top of the air duct cover, the invention further optimizes the cold air flow path. The guide plates direct the cold air generated by the evaporator to the centrifugal fan's intake, improving the fan's intake efficiency and reducing cold air loss. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides a novel refrigerated display cabinet with a transparent glass door and air duct, such as... Figures 1-7As shown, the display case includes a cabinet 1, which comprises an outer shell 11 and an inner liner 12. An insulation layer is provided between the outer shell 11 and the inner liner 12. A circulating air duct is installed inside the inner liner 12, comprising an air duct system 4 and an air duct plate 5. The air duct plate 5 divides the interior of the inner liner 12 into several vertical air ducts. The air duct system 4 is installed on the back of the inner liner 12 to create circulating air within it. The air duct system 4 includes an evaporator 43 and a centrifugal fan 44. An air duct cover 41 is installed on one side of the evaporator 43 and the centrifugal fan 44. The insulation layer between the outer shell 11 and the inner liner 12 is designed primarily to reduce heat loss and improve the display case's insulation performance. The insulation layer is typically made of materials with good thermal insulation properties, such as polyurethane foam, to ensure that the display case maintains a stable internal temperature during long-term operation. The inner liner 12 is the main space in the display case for storing items, and it is specially designed with a circulating air duct. The purpose of this circulating air duct is to achieve uniform distribution and circulation of cold air inside the display case, thereby improving cooling efficiency and temperature uniformity. The circulating air duct consists of two key components: the air duct system 4 and the air duct plate 5. The air duct plate 5 divides the interior of the inner liner 12 into several vertical air ducts. These vertical air ducts help guide and regulate the flow path of cold air, ensuring that cold air can evenly cover every corner of the display case. By rationally arranging the vertical air ducts, not only can the cooling efficiency of the display case be improved, but temperature dead zones can also be effectively avoided, ensuring the quality of the stored items. The air duct system 4 is installed at the back of the inner liner 12, and its main function is to create circulating air within the inner liner 12. Specifically, the air duct system 4 includes two main parts: an evaporator 43 and a centrifugal fan 44. The evaporator 43 is an important component of the refrigeration system; it is responsible for absorbing heat from inside the display case and transferring this heat to the external environment through the refrigeration cycle. Centrifugal fan 44 is responsible for driving the flow of cold air in the circulating air duct, ensuring that the cold air can pass smoothly through each vertical air duct, and achieving uniform cooling inside the display case.

[0027] To further optimize the performance of the circulating air duct, an air duct cover 41 is installed on one side of the evaporator 43 and the centrifugal fan 44. The design of the air duct cover 41 not only protects the evaporator 43 and the centrifugal fan 44, but also guides and regulates the flow direction and speed of cold air through its special structure and layout. For example, some guide grooves or guide holes can be provided on the air duct cover 41 to ensure that cold air enters the circulating air duct at the optimal angle and speed, thereby improving cooling efficiency and temperature uniformity.

[0028] In this embodiment, a cabinet door 2 is installed on the front of the box 1, and a refrigeration system 3 is installed at the bottom of the box 1. The refrigeration system 3 includes a lower front cover, and a condenser and a compressor are installed inside the lower front cover. The evaporator 43, the condenser and the compressor are connected by pipes to form a refrigeration circuit.

[0029] Specifically, an air guide is provided at the top of the air duct cover 41 near the air inlet of the evaporator 43, and several air guide plates 411 are installed at the air guide for guiding air.

[0030] Furthermore, the air outlet of the evaporator 43 is located at the bottom, a fan cover 42 is installed on the outside of the centrifugal fan 44, an air intake 45 is provided on one side of the centrifugal fan 44, and an air exhaust 47 is provided at the bottom of the centrifugal fan 44.

[0031] Furthermore, an inclined surface 421 is installed on the upper part of the fan cover 42. The inclined surface 421 guides the air outlet of the evaporator 43 and directs the cold air to the air intake 45, where it is drawn in by the centrifugal fan 44.

[0032] Furthermore, a wind deflector 46 is installed at the lower part of the air intake 45 to block the wind and prevent cold air from moving downward away from the air intake 45.

[0033] Furthermore, the air guide plates 411 are arranged at equal intervals to facilitate the uniform entry of air.

[0034] Furthermore, a baffle plate 422 is installed inside the fan cover 42 to guide the drawn-in cold air to the exhaust port 47 for discharge.

[0035] When the novel refrigerated display case with a transparent glass door and air duct of this invention is in use, the compressor in the refrigeration system 3 starts operating after the display case is powered on and begins to work, driving the refrigerant to circulate in the refrigeration circuit. The refrigerant absorbs heat from inside the display case and evaporates in the evaporator 43, thereby lowering the temperature inside the display case. At the same time, the condenser discharges the heat released by the refrigerant to the external environment of the display case. In this way, through the circulation of the refrigerant, a low temperature environment is maintained inside the display case.

[0036] During the refrigeration process, the cold air generated by the evaporator 43 needs to be evenly distributed to all corners of the display case through the circulating air duct. At this time, the centrifugal fan 44 starts working, drawing in the cold air generated by the evaporator 43 through the air intake 45. The inclined surface 421 on the upper part of the fan cover 42 is cleverly designed to connect the air outlet of the evaporator 43 with the air intake 45, ensuring that the cold air can be smoothly drawn into the fan. At the same time, the wind deflector 46 at the lower part of the air intake 45 acts as a wind deflector, preventing the cold air from flowing downwards away from the air intake and improving the intake efficiency.

[0037] Centrifugal fan 44 draws in cold air, which is then guided through deflector plate 422 inside fan cover 42 to exhaust port 47, and then evenly discharged into the circulating air duct. Air duct plate 5 in the circulating air duct divides the inner liner 12 into several vertical air ducts, ensuring that cold air can flow evenly along these ducts to every corner of the display case. In this way, the items inside the display case can be preserved in a uniformly low-temperature environment.

[0038] In addition, to further optimize the performance of the circulating air duct, an air duct cover 41 is installed on one side of the evaporator 43 and the centrifugal fan 44. The air guides and guide plates 411 on the air duct cover 41 are designed to guide and regulate the flow direction and speed of cold air, ensuring that cold air enters the circulating air duct at the optimal angle and speed. This not only improves cooling efficiency but also ensures a more uniform temperature inside the display case.

[0039] Finally, it should be noted that the electronic components in the evaporator 43, condenser, and compressor in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

All of these are technologies known in the art.
