Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration equipment, in particular to vertical air curtain cabinet equipment. Background Art
[0002] A vertical air curtain cabinet is a display-type refrigerator with a side opening. Due to the side opening of the refrigerator, the density of cold air is greater than that of air at room temperature, and the cold air is easily lost. Therefore, the vertical air curtain cabinet generally uses a fan to circulate the air inside the cabinet so that the cold air only flows inside the cabinet. The compressor used for refrigeration in the vertical air curtain cabinet has two structures: internal and external. The internal compressor can realize the large cabinet structure of the refrigerator. For vertical air curtain cabinets with internal compressors, the compressor is usually arranged on the back of the cabinet, and part or all of the structure is located in the internal air duct. Existing vertical air curtain cabinets usually set the compressor on one side of the cabinet to facilitate wiring. This results in different flow resistance of the internal air ducts on both sides of the cabinet, and the distribution of cold air in the internal air duct is uneven, making the temperature inside the refrigerator inconsistent. The cabinet temperature on one side is significantly higher than that on the other side, and the refrigeration effect is poor.
[0003] In addition, the built-in compressor will transfer heat to the internal air duct, affecting the cooling efficiency. Utility Model Content

[0016] Beneficial effects of the utility model:
[0017] The utility model provides a vertical air curtain cabinet device, wherein a cooling channel is formed between the inner and outer shells of the cabinet assembly. A partition is disposed within the cooling channel and divides the cooling channel into a first cooling channel and a second cooling channel. Two sets of evaporator assemblies are disposed within the first and second cooling channels, respectively, so that cool air can flow within the first and second cooling channels, respectively, and the cool air flows toward the storage cavity to form an air curtain.

[0031] like Figures 1 to 6 As shown, this embodiment provides a vertical air curtain cabinet device, which includes a cabinet assembly 1 that encloses a storage cavity 15 and multiple compressors 2. The cabinet assembly 1 includes an inner shell 11, an outer shell 12, and a partition 13. A cooling channel 10 is formed between the inner shell 11 and the outer shell 12. The partition 13 is disposed within the cooling channel 10 and separates the cooling channel 10 to form a first cooling channel and a second cooling channel.
[0032] The vertical air curtain cabinet device also includes two groups of evaporator assemblies 3, which are respectively arranged in the first cooling channel and the second cooling channel, so that flowing cold air can be formed in the first cooling channel and the second cooling channel respectively, and the cold air flows to the storage cavity 15 to form an air curtain. The back panel of the outer shell 12 is provided with multiple installation ports 121 connected to the cooling channel 10, and the first cooling channel and the second cooling channel each correspond to at least one installation port 121; the multiple installation ports 121 correspond one-to-one to the multiple compressors 2. The cabinet assembly 1 also includes two air guide covers 14, one of which is connected to the outer shell 12 and protrudes toward the first cooling channel to form a first installation space connected to several installation ports 121, and the other air guide cover 14 is connected to the outer shell 12 and protrudes toward the second cooling channel to form a second installation space connected to the remaining installation ports 121. Each compressor 2 is at least partially located in the first installation space or the second installation space. Under the guidance of the two air guide covers 14, whether the number of compressors 2 in the first installation space is the same as the number of compressors 2 in the second installation space will not affect the wind resistance in the first cooling channel and the second cooling channel. The two air guide covers 14 guide the cold air in the first cooling channel and the second cooling channel respectively, allowing it to flow smoothly through their respective evaporator assemblies 3, thereby forming a uniform wind curtain in the storage cavity 15, reducing the wind curtain wind phenomenon, achieving uniform temperature at different locations in the storage cavity 15, and improving the refrigeration effect. In addition, the air guide covers 14 have a heat insulation effect, reducing the heat from the compressor 2 from being transferred to the first cooling channel and the second cooling channel, thereby avoiding affecting the cooling efficiency of the evaporator assembly 3.
[0033] The material of the air guide cover 14 is polyurethane. High-density polyurethane (PU) has better stability, chemical resistance, resilience and mechanical properties, smaller compression deformation, and good heat insulation, sound insulation and shock resistance.
[0034] For example, Figure 3 As shown, a plurality of mounting openings 121 are arranged at intervals along the width direction of the back plate, that is, a plurality of compressors 2 are arranged at intervals along the horizontal direction.
[0035] The evaporator assembly 3 includes an evaporator fan 31 and an evaporator 32. The evaporator fan 31 is used to blow the cold air that has been cooled by the evaporator 32, forming an air circulation system. The specific structure and cooling principle of the evaporator assembly 3 can be configured with reference to the existing technology. This is not the focus of this application and is not described in detail in this embodiment.
[0036] The outer shell 12 includes a first insulation board 122 and a second insulation board 123 spaced apart, forming an insulation cavity 124 between the first insulation board 122 and the second insulation board 123. The double-layer structure improves the thermal insulation effect of the outer shell 12 and reduces heat exchange between the first cooling channel and the second cooling channel and the outside world.
[0037] In one embodiment, to further enhance the thermal insulation of the outer shell 12 , the thermal insulation cavity 124 is filled with thermal insulation foam. Compared to a hollow cavity, the thermal insulation foam has better thermal insulation and heat preservation properties, effectively reducing energy loss within the first cooling channel and the second cooling channel. This embodiment does not restrict the material of the thermal insulation foam.
[0038] like Figure 4 and Figure 5 As shown, the outer shell 12 also includes an insulating edging member 125, which is arranged at the mounting port 121 and extends circumferentially along the mounting port 121. The insulating edging member 125 is connected to the outer shell 12 to isolate the insulating cavity 124 and the mounting port 121, so that the insulating cavity 124 and the mounting port 121 are isolated, thereby preventing the working heat of the compressor 2 at the mounting port 121 from being transferred to the insulating foam in the insulating cavity 124.
[0039] Specifically, if Figure 6 As shown, the thermal insulation edging member 125 includes a first connecting frame 1251, a second connecting frame 1252 and a third connecting frame 1253. The first connecting frame 1251 and the second connecting frame 1252 are respectively vertically connected to the two ends of the third connecting frame 1253. Therefore, the cross-sectional shape of the thermal insulation edging member 125 is U-shaped. Figure 6 In order to make the shape of the heat-insulating edging member 125 compatible with the mounting opening 121, the heat-insulating edging member 125 is composed of four edging members, which are connected end to end to form the heat-insulating edging member 125. Each edging member has a first connecting frame 1251, a second connecting frame 1252, and a third connecting frame 1253, and each edging member has a U-shaped cross-section.
[0040] The third connecting frame 1253 is sandwiched between the first insulation board 122 and the second insulation board 123 to enclose the insulation cavity 124. The first connecting frame 1251 is connected to the first insulation board 122, and the second connecting frame 1252 is connected to the second insulation board 123. The insulation edging member 125 is connected by bonding or screws to achieve the connection between the first connecting frame 1251 and the first insulation board 122, and the connection between the second connecting frame 1252 and the second insulation board 123.
[0041] The first connection frame 1251 can be attached to the inside or outside of the first thermal insulation board 122. In one embodiment, the first connection frame 1251 is attached to the inside of the first thermal insulation board 122 so as to be located within the cooling channel 10, and the air guide cover 14 is attached to the first connection frame 1251. That is, when the thermal insulation edging 125 is attached to the mounting opening 121 corresponding to the first cooling channel, the first connection frame 1251 is attached to the inside of the first thermal insulation board 122 so as to be located within the first cooling channel; when the thermal insulation edging 125 is attached to the mounting opening 121 corresponding to the second cooling channel, the first connection frame 1251 is attached to the inside of the first thermal insulation board 122 so as to be located within the second cooling channel. The air guide cover 14 is attached to the first connection frame 1251 and is not directly connected to the outer shell 12. This reduces heat conduction between the outer shell 12 and the air guide cover 14, reduces energy loss within the cooling channel 10, and prevents the formation of condensation within the cooling channel 10.
[0042] The second connection frame 1252 is connected to the outside of the second insulation board 123. The vertical air curtain cabinet equipment also includes multiple insulation covers 4, each corresponding to a plurality of compressors 2. The insulation covers 4 are connected to the second connection frame 1252 to close the installation opening 121. The insulation covers 4 provide protection for the compressors 2 and reduce the heat transfer from the compressors 2 to the outer shell 12.
[0043] To further improve performance, the heat-insulating edging 125 is made of plastic. Compared to metal, plastic has a poorer heat conduction effect, thus preventing external heat from being transferred into the cooling channel 10 through the first heat-insulating plate 122. Moreover, due to the large temperature difference between the inside and outside of the outer shell 12, the heat-insulating edging 125 made of plastic is less susceptible to condensation, thereby preventing condensation from corroding structural components.
[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
