[0028] In a general refrigeration device, the air duct assembly arranged at the side will occupy the space at the side of the storage space in the refrigeration device, thereby resulting in a reduction in the storage space of the refrigeration device.

[0029] Based on the above questions, please refer to Figure 1The present application provides an air duct assembly for a refrigeration device, including an air duct body 100, which is cylindrical in shape, specifically, a prism, a cylinder, etc. The air duct body 100 is configured to extend along the length direction of the refrigeration device, that is, the length direction of the cylindrical air duct body 100 is consistent with the length direction of the refrigeration device. The air duct body 100 is surrounded by a hollow cavity 101 for transporting cooling air. Taking the normal working state of the refrigeration device as a reference, the length direction of the refrigeration device is the height direction of the refrigeration device. First of all, since the air duct body 100 extends along the length direction and has a cylindrical shape, its transverse cross-section is small. When placed in the refrigeration device, the space occupied on the side of the refrigeration device is also small. The cylindrical air duct of the present application can be set at the corner of the side of the inside of the refrigeration device, which can greatly improve the space utilization in the refrigeration device.

[0030] Furthermore, according to Bernoulli's principle, when the air duct is transporting cooling air, since the transverse cross-section of the air duct body 100 is small, the flow rate of the cooling air in the hollow cavity is large, thereby increasing the circulation speed of the cooling air in the refrigeration device.

[0031] In one embodiment, please combine Figure 2 and Figure 3 , the extension direction of the air duct body 100 is the first direction, and the hollow cavity 101 is provided with a reverse air rib 110, and the reverse air rib 110 is extended along the first direction, that is, the reverse air rib 110 is extended in the same direction as the air duct body 100. The reverse air rib 110 divides the hollow cavity 101 into at least two wind guide spaces extending along the first direction. For example, a reverse air rib 110 is provided in the hollow cavity 101, and the reverse air rib 110 cuts the hollow cavity 101 into two wind guide spaces. When the cooling air circulates in the hollow cavity 101, a cyclone may be generated, which causes the circulation speed of the cold air to slow down. In the present application, due to the presence of the reverse air rib 110, the reverse air rib 110 can interrupt the formation of the cyclone, reduce the cyclone phenomenon of the cooling air in the air duct, and make the cooling air circulate from the two wind guide spaces, further increasing the cooling air circulation speed of the refrigeration device.

[0032] In another embodiment, a plurality of reverse air ribs 110 are provided along the circumference of the air duct body, dividing the hollow cavity 101 into a plurality of wind guide spaces distributed along the circumference. The cooling air can flow through the plurality of wind guide spaces, separating the cyclones more thoroughly, and further accelerating the circulation speed of the cooling air in the hollow cavity 101. And a plurality of reverse air ribs 110 are connected to the shaft extending along the first direction. The shaft extending along the first direction can be fixedly installed at the top and bottom of the refrigeration device through both ends of the shaft, thereby fixing the reverse air ribs 110 in the refrigeration device.

[0033] Please combine Figure 2The present application also provides a refrigeration device, including any of the above-mentioned air duct assemblies. A storage chamber 200 is formed inside the refrigeration device, and the air duct body 100 is arranged in the storage chamber 200, and an air outlet 120 is opened at one end of the air duct body 100 close to the bottom of the storage chamber 200. The bottom here refers to the part close to the placement surface of the refrigeration device when the refrigeration device is in normal working condition. The air outlet 120 connects the hollow cavity 101 with the storage chamber 200. The cooling air in the hollow cavity 101 flows into the storage chamber 200 from the air outlet 120. The cooling air is introduced from the bottom of the storage chamber 200 and slowly fills the entire storage chamber 200 from the bottom to the top. Since the density of cooling air is heavier than air, it can be introduced from the bottom to the top, so that the cooling air can fill the storage chamber 200 more thoroughly, so that the refrigeration effect of the refrigeration device is better.

[0034] In one embodiment, a first space 210 is provided at the top of the storage chamber 200, the first space 210 is connected to the hollow cavity 101, a fan 211 and an evaporator 212 are provided in the first space 210, an air inlet 220 is provided between the first space 210 and the storage chamber 200, and the fan 211 is configured to extract gas inside the storage chamber 200 through the air inlet 220, and heat exchange with the evaporator 212 in the first space 210. The fan 211 extracts gas from the top of the storage chamber 200, forms cooling air after heat exchange with the evaporator in the first space 210, and then transports the cooling air to the bottom of the storage chamber 200 through the air duct body 100, forming a cooling air flow as shown in FIG. Figure 4 The cooling air circulation indicated by the middle arrow enables the present application to continuously introduce cooling air into the storage chamber 200 , thereby ensuring the refrigeration effect of the storage chamber 200 .

[0035] In another embodiment, in combination Figure 2 The first space 210 is surrounded by the baffle 201 and the top wall of the storage chamber 200. The baffle 201 surrounds the fan 211 and the evaporator 212 on the side close to the air duct body 100. The shape of the baffle 201 is consistent with the outer contour of the fan 211 and the evaporator 212 after being set together, so that the fan 211 and the evaporator 212 can be more compactly surrounded together, so that the gas inside the storage chamber 200 extracted from the air inlet 220 can more effectively achieve heat exchange in the first space 210.

[0036] In one embodiment, in combination Figure 2 and Figure 4, the storage room 200 is surrounded by a refrigeration device shell 300. The side wall of the refrigeration device shell 300 is surrounded by a first side wall 310, a second side wall 320 and a third side wall 330, and at least one of the first side wall 310, the second side wall 320 and the third side wall 330 is arc-shaped. When the refrigeration device is a display freezer in a shopping mall, the arc-shaped side wall can be used as a display surface of the freezer. The arc-shaped display surface has a wider field of view and can display the items in the storage room 200 in a more three-dimensional manner, with a better and more novel display effect. The arc-shaped side wall can be made of transparent glass or plastic, and is connected to the other two side walls through a PVC (polyvinyl chloride) extrusion frame.

[0037] In one embodiment, in combination Figures 2 to 4 The air duct body 100 is arranged at the corner where the first side wall 310 and the second side wall 320 intersect, and the air duct body 100 is surrounded by the first side wall 310, the second side wall 320, and the third side wall 130 of the air duct body, and a sealing strip is arranged at the intersection of the third side wall 130 of the air duct body with the first side wall 310 and the second side wall 320. In this embodiment, the air duct body 100 uses the first side wall 310 and the second side wall 320 as the structure of the air duct body 100. It is only necessary to arrange the third side wall 130 of the air duct body at the corner of the refrigeration device shell 300, and the original corner can be used to enclose the air duct body 100. It not only effectively utilizes the internal space of the refrigeration device, but also saves the materials required to enclose the air duct body 100. Further arranging a sealing strip at the intersection can ensure the sealing effect of the air duct body 100.

[0038] In one embodiment, the projection of the refrigeration device housing 300 along its extension direction is a sector shape, and the sector shape is a quarter circle. Taking the third side wall 330 as an arc-shaped side wall as an example, the first side wall 310 and the second side wall 320 are in the same plane, and the corners of the first side wall 310 and the second side wall 320 are perpendicular to each other. In this embodiment, combined with Figure 5 The refrigeration device can match the angle of the corner through the first side wall 310 and the second side wall 320, so that the refrigeration device can be placed in the corner. Figure 6 The two refrigeration devices can also be combined, and the two first side walls 310 form a plane, so that the refrigeration device can be placed against the wall. Figure 7 , you can also combine four refrigeration units to form a cylindrical display cabinet, which can be displayed in all directions. Figure 8 , and the fan-shaped refrigeration device of the present application can also be combined with a square refrigerator commonly used on the market for display. Therefore, the refrigeration device provided in this embodiment has various shapes and can be combined in various ways. The specific assembly method is not limited to the above-mentioned examples, and can be flexibly combined according to the specific placement scene and customer needs, greatly improving the adaptability of the display refrigeration device to the scene.

[0039] In one embodiment, in combination Figure 2 and Figure 4 The bottom of the storage room 200 is provided with a compressor cabin 230; the side walls of the compressor cabin 230 adjacent to the first side wall 310 and the second side wall 320 are respectively provided as the air inlet surface and the air outlet surface of the compressor cabin 230. Compared with the traditional refrigeration device which only has one surface for air inlet and air outlet, the present embodiment provides two surfaces as the air inlet surface and the air outlet surface, so that the air inlet and air outlet area of ​​the compressor cabin 230 is increased by 2 times compared with the traditional refrigeration device, thereby improving the heat exchange efficiency of the compressor cabin.

[0040] In one embodiment, in combination Figure 2 The bottom of the storage room 200 is provided with a pressurizing chamber 230, and the pressurizing chamber 230 is provided with a water receiving pan 500, and the water receiving pan 500 is connected with the air duct body 100 through a water receiving pipe. In the air duct body 100, the cooling water generated due to the temperature difference between the inside and the outside can flow into the water receiving pan 500 through the water receiving pipe and be collected, thereby preventing the cooling water from accumulating and affecting the refrigeration performance of the refrigeration device.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
