The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it independent or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0055] The embodiment of the present application provides a refrigeration system 120 of a refrigeration cabinet, which is mainly suitable for a refrigeration cabinet 100, of course, and can also be suitable for other suitable refrigeration equipment. The refrigeration cabinet 100 described herein includes but is not limited to a retail cabinet, a display cabinet, etc.

[0056] Taking a conventional vertical refrigeration cabinet as an example, the refrigeration cabinet 100 includes a cabinet body 110 and a plurality of shelves 130, wherein the cabinet body 110 is internally provided with an inner cavity 111, and the plurality of shelves 130 are arranged in the inner cavity 111 in a layered gap along the extension direction of the cabinet body 110.

[0057] In the embodiment of the utility model, as shown in Figure 2 The refrigeration system 120 of the refrigeration cabinet includes a partition plate 121 and an evaporative assembly. The partition plate 121 is arranged in the inner cavity 111 along the extension direction of the cabinet body 110 to at least divide the inner cavity 111 into a storage cavity 1111 and an air duct 1112. The storage cavity 1111 is provided with a storage rack 130. At the corresponding position between the adjacent two layers of storage racks 130, the partition plate 121 is provided with an air outlet 1211 that communicates the air duct 1112 and the storage cavity 1111.

[0058] Understandably, the inner cavity 111 area is divided by the newly added partition plate 121 to divide the storage cavity 1111 and the air duct 1112 that are isolated from each other by the partition plate 121, and the storage cavity 1111 and the air duct 1112 can be communicated through the air outlet 1211 on the partition plate 121. The uniformity of the temperature in the storage cavity 1111 is ensured through the air outlet 1211.

[0059] Exemplarily, the partition plate 121 is arranged on one side of the cabinet body 110 close to the back of the cabinet body 110, and the shape and size of the partition plate 121 are adapted to the shape and size of the corresponding position of the inner cavity 111, so as to ensure that the storage cavity 1111 and the air duct 1112 can be separated.

[0060] In addition, the opening position and size of the air outlet 1211 can be determined according to actual needs, which is not particularly limited here, as long as the cold air / cold water can be delivered to the bottom of the inner cavity 111, which is beneficial to ensure that the temperature in the storage cavity 1111 is relatively uniform.

[0061] In the embodiment of the utility model, as shown in Figure 2 The evaporative assembly is located in the air duct 1112 and close to the top of the cabinet body 110. The evaporative assembly at least includes a blower 122 and an evaporator 123. In the direction from the top to the bottom of the cabinet body 110, the blower 122 and the evaporator 123 are arranged along the air duct 1112 and are arranged in the air duct 1112 in sequence with a gap. The blower 122 can be used to deliver the hot air flow at the top of the storage cavity 1111 in a direction away from the top of the storage cavity 1111 to the evaporator 123.

[0062] Understandably, by setting the air blower 122 and the evaporator 123 of the evaporation assembly in the air duct 1112, on the one hand, the space occupied by the evaporation assembly in the inner cavity 111 is reduced, so that the original storage space of the articles can be expanded by partitioning the inner cavity 111 by the partition plate 121 and adjusting the installation position of the air blower 122, so as to obtain a storage cavity 1111 with a larger effective volume; on the other hand, the air exchange between the storage cavity 1111 and the evaporator 123 is concentrated in the air duct 1112 and is delivered to the storage cavity 1111 through the corresponding air outlets 1211, which obviously helps to reduce energy consumption and noise.

[0063] Exemplarily, on the same side of the partition plate 121, the air blower 122 is arranged at the top of the air duct 1112, and the evaporator 123 is located below the air blower 122, wherein the air blower 122 communicates with the storage cavity 1111 and the air duct 1112, and the air blower 122 can quickly deliver the hot air flow at the top of the storage cavity 1111 (see the red arrow in Figure 2 ) to the air duct 1112, and quickly deliver the hot air flow from the top to the bottom of the air duct 1112 to the evaporator 123, so that the liquid refrigerant in the evaporator 123 can exchange heat with the hot air flow in the air duct 1112 to absorb heat and vaporize into gaseous refrigerant for recovery. The hot air flow is converted into a cold air flow (see the green arrow in Figure 2 ) after absorbing heat, and the cold air flow can enter the corresponding layer through each air outlet 1211 in the air duct 1112 to cool the articles in the layer, and finally flow to the top of the storage cavity 1111 to form an air flow circulation.

[0064] It should be noted that the air blower 122 is mainly used to enhance the convective heat exchange efficiency between the evaporator 123 and the air in the air duct 1112, and to accelerate the delivery of the cold air flow output by the evaporator 123 to the storage cavity 1111. In addition, the paths of the hot air flow and the cold air flow described herein are not strictly limited in actual application, and the schematic diagram in this paper Figure 2 is only a general delivery path.

[0065] In summary, compared with the prior art, the refrigeration system 120 of the refrigeration cabinet has at least the following beneficial effects:

[0066] The refrigeration system 120 of the refrigeration cabinet divides the inner cavity 111 into the storage cavity 1111 and the air duct 1112 by the newly added partition plate 121, and the air supply fan 122 and the evaporator 123 of the evaporation assembly are arranged in the air duct 1112 along the extension direction of the air duct 1112 without changing the total size of the cabinet body 110. On the one hand, the space of the air duct 1112 can be fully utilized without occupying the space of the storage cavity 1111, that is, by adjusting the space layout of the inner cavity 111 and the installation layout structure of the evaporation assembly through the partition plate 121, the effective volume of the storage cavity 1111 can be increased, at least one layer of the shelf 130 can be added in the storage cavity 1111, the large storage space requirement of the user can be met, the cost performance can be improved, and the use experience of the user can be improved. On the other hand, the air flow heat exchange between the storage cavity 1111 and the evaporator 123 can be concentrated in the air duct 1112 and delivered to the storage cavity 1111 through the corresponding air outlet 1211, instead of being dispersedly exchanged in the whole inner cavity 111, so that the uniformity of the temperature in the storage cavity 1111 can be ensured, and the energy consumption and the noise can be reduced.

[0067] In order for those skilled in the art to better understand the technical scheme of the present application, the following will combine the accompanying drawings to Figure 2 The technical scheme in the embodiments of the present application is clearly and completely described.

[0068] In some embodiments of the present application, as shown in Figure 2 In order to improve the compactness, the air supply fan 122 is vertically arranged on the partition plate 121.

[0069] In some embodiments, as shown in Figure 2 The evaporator 123 is vertically arranged on the rear cavity wall of the cabinet body 110. In this way, there is no gap between the evaporator 123 and the rear cavity wall of the cabinet body 110, which is beneficial to improving the compactness and simplifying the overall structure. On the other hand, the hot air output by the air supply fan 122 can only be directly downwardly delivered from the top of the air duct 1112, so that the hot air needs to pass through the evaporator 123 along the length direction of the evaporator 123. Obviously, the contact path of the hot air and the fins of the evaporator 123 is longer, which is beneficial to improving the working efficiency of the evaporator 123 by sufficient contact, thereby reducing the energy consumption and the noise.

[0070] Exemplarily, as shown in Figure 2 The air supply fan 122 is vertically arranged on one side of the partition plate 121 close to the air duct 1112, and the evaporator 123 is vertically arranged on one side of the rear cavity wall of the cabinet body 110 close to the air duct 1112. The air supply fan 122 and the evaporator 123 are gap arranged in the extension direction of the air duct 1112, and the air supply fan 122 overlaps the evaporator 123 in the thickness direction of the air supply fan 122 in order to improve the air flow exchange efficiency and reduce the width of the air duct 1112.

[0071] In some embodiments of the present application, as shown in Figure 2 To improve the compactness of the structure and further increase the effective volume of the storage cavity 1111, the partition plate 121 is parallel to the rear cavity wall of the cabinet 110.

[0072] In some embodiments, to improve the compactness of the structure and further increase the effective volume of the storage cavity 1111, the air blower 122 is vertically arranged parallel to the partition plate 121.

[0073] In some embodiments, to improve the compactness of the structure and further increase the effective volume of the storage cavity 1111, the evaporator 123 is vertically arranged parallel to the partition plate 121.

[0074] Exemplarily, as shown in Figure 2 In this embodiment, the partition plate 121 is parallel to the rear cavity wall of the cabinet 110 and is vertically arranged in the inner cavity 111. The air blower 122 and the evaporator 123 are parallel to the partition plate 121, and the air blower 122 and the evaporator 123 only need to be arranged with a spacing of several millimeters. In this way, under the condition that the occupied space of the air duct 1112 is as small as possible, the hot air flow sent out by the air blower 122, which is concentrated in the space formed between the air blower 122, the evaporator 123 and the rear cavity wall of the inner cavity 111, can also enter the evaporator 123 as soon as possible along the extension direction of the air duct 1112, which is beneficial to further reduce energy consumption and reduce the use cost of the user.

[0075] In some embodiments of the present application, as shown in Figure 2 To realize the refrigeration function, the refrigeration system 120 further includes a compressor 124, a condenser (not shown in the figure) and a throttling device (not shown in the figure) located outside the inner cavity 111. The air duct 1112 of the cabinet 110 is provided with a water collecting groove 112, which is located at the bottom of the air duct 1112 and is used to receive the condensed water dripping down from the evaporator 123. The compressor 124 is provided with a water collecting container 1241, which is connected to the water collecting groove 112 through a water outlet pipe 125 and is used to collect the condensed water in the water collecting groove 112.

[0076] It should be noted that, in order to realize the refrigeration function, the refrigeration system 120 can further include a condenser fan (not shown in the figure), a drying filter (not shown in the figure), a water collecting pipe (not shown in the figure), an exhaust pipe (not shown in the figure), a throttling pipe (not shown in the figure) and a return air pipe (not shown in the figure), wherein the two ends of the exhaust pipe are respectively connected to the compressor 124 and the condenser, the two ends of the throttling pipe are respectively connected to the drying filter and the evaporator 123, and the two ends of the return air pipe are respectively connected to the evaporator 123 and the compressor 124. It should be particularly pointed out that the compressor 124, the exhaust pipe, the condenser and the drying filter should be thermally insulated outside the inner cavity 111 to prevent the heat emitted from entering the inner cavity 111. The throttling pipe and the return air pipe need to be taken out of the inner cavity 111 and also need to be thermally insulated.

[0077] More specifically, the evaporator 123, the air supply fan 122 and the water collecting groove 112 are all located in the air duct 1112, and during refrigeration, the condensed water of the evaporator 123 drops into the water collecting groove 112 and flows to the water collecting container 1241 of the compressor 124 through the water outlet pipe 125, and then the heat of the compressor 124 and the condenser fan can evaporate the condensed water in the water collecting container 1241, and then the compressor 124 sucks in the low-pressure condensed water vapor and compresses it into high-pressure high-temperature gaseous refrigerant, which is delivered to the condenser through the exhaust pipe. The gaseous refrigerant is cooled and condensed into high-pressure liquid refrigerant in the condenser, and the moisture in the high-pressure liquid refrigerant is dried and impurities are filtered by the drying filter, and the dried and filtered high-pressure liquid refrigerant is throttled and reduced in pressure by the throttling pipe and delivered to the evaporator 123. The liquid refrigerant in the evaporator 123 exchanges heat with the hot air stream delivered by the air supply fan 122 in the air duct 1112 to absorb the heat of the hot air stream to obtain cold air stream, and the liquid refrigerant itself can be gasified into gaseous refrigerant after absorbing heat. The cold air stream in the air duct 1112 can enter the storage cavity 1111 from the air duct 1112 through the air outlet 1211 to cool the temperature of the corresponding layer in the storage cavity 1111, and the gaseous refrigerant can be sucked into the compressor 124 through the return air pipe to form a cycle.

[0078] Of course, in other embodiments, the refrigeration part of the refrigeration system 120 can also use other existing or newly created structures, which are not particularly limited here.

[0079] The utility model embodiment further provides another refrigeration system 120 of refrigeration cabinet, wherein the refrigeration cabinet 100 includes a cabinet body 110 and a plurality of layers of storage shelves 130, the cabinet body 110 is internally provided with an inner cavity 111, and the plurality of layers of storage shelves 130 are arranged in the inner cavity 111 in a layered and spaced manner along the extension direction of the cabinet body 110. It should be noted that the number of layers of the storage shelves 130 can be determined according to the actual size of the inner cavity 111, which is not particularly limited here.

[0080] In the embodiment of the utility model, as shown in Figure 2 The refrigeration system 120 of the refrigeration cabinet comprises a partition plate 121, an evaporating assembly, a compressor 124 and a condenser, wherein the partition plate 121 is vertically arranged in the inner cavity 111 of the cabinet body 110 to divide the inner cavity 111 into at least a storage cavity 1111 and an air duct 1112. The storage cavity 1111 is provided with a storage rack 130; the bottom of the air duct 1112 is provided with a water collecting groove 112. As shown in Figure 2 The evaporating assembly comprises a blowing fan 122 and an evaporator 123 arranged in the air duct 1112, wherein the blowing fan 122 is vertically arranged on the partition plate 121, and the evaporator 123 is vertically arranged on the rear cavity wall of the inner cavity 111 of the cabinet body 110; the blowing fan 122 can be used to send the air flow at the top of the storage cavity 1111 to the evaporator 123 in a direction away from the top of the storage cavity 1111.

[0081] As shown in Figure 2 The compressor 124 is arranged outside the inner cavity 111 and is provided with a water collecting container 1241, the water collecting container 1241 is communicated with the water collecting groove 112 through a water outlet pipe 125 and is used to collect the condensed water collected by the water collecting groove 112 in the air duct 1112. The condenser is arranged outside the inner cavity 111 and is connected with the compressor 124 and the evaporator 123.

[0082] Understandably, the inner cavity 111 is divided by the newly added partition plate 121 to divide the storage cavity 1111 and the air duct 1112 which are isolated from each other by the partition plate 121, the storage cavity 1111 and the air duct 1112 can be communicated through the air outlet 1211 on the partition plate 121 to ensure the uniformity of the temperature in the storage cavity 1111 through the air outlet 1211. And by adjusting the installation structure of the evaporating assembly, the blowing fan 122 and the evaporator 123 are arranged in the air duct 1112, and the blowing fan 122 is vertically arranged on the partition plate 121, and the evaporator 123 is vertically arranged on the rear cavity wall of the inner cavity 111 of the cabinet body 110, on the one hand, to minimize the occupied space of the air duct 1112, and to make full use of the space of the air duct 1112, so as to reduce the occupied space of the evaporating assembly in the inner cavity 111, thereby realizing the expansion of the original storage space of the articles in the inner cavity 111 of the same size, so as to obtain a storage cavity 1111 with a larger effective volume, on the other hand, the air exchange between the storage cavity 1111 and the evaporator 123 can be concentrated in the air duct 1112 and delivered to the storage cavity 1111 through the corresponding air outlet 1211, which is conducive to reducing energy consumption and noise.

[0083] It should be noted that the opening position and size of the air outlet 1211 can be determined according to actual needs, which is not particularly limited here, as long as the cold air / water can be delivered to the bottom of the inner cavity 111 to ensure that the temperature in the storage cavity 1111 is relatively uniform.

[0084] In some embodiments of the present application, as shown in Figure 2 To further increase the effective volume of the storage cavity 1111, the partition plate 121 is parallel to the rear cavity wall of the cabinet 110.

[0085] In some embodiments, to further increase the effective volume of the storage cavity 1111, the air blower 122 and the evaporator 123 are parallel to the partition plate 121.
