DETAILED DESCRIPTION
[0019] In order to make the purpose, technical scheme and advantages of the utility model embodiment more clear, the utility model technical scheme will be clearly and completely described below in combination with the embodiments.
[0020] Figure 1A schematic diagram of the overall structure of a refrigerated display case with a circulating air guide structure is shown. Figure 2 A schematic diagram of the cold air flow structure of a refrigerated display case with a circulating air guide structure is shown.
[0021] Figure 1 and Figure 2 The refrigerated display case with a circulating air guide structure includes a cabinet body 100 and a circulation channel 200 disposed within the cabinet body 100. The cabinet body 100 has a display space 110, and multiple sets of horizontally arranged display panels 120 are arranged at intervals along the vertical direction in the display space 110. All display panels 120 have a hollow design. The horizontally arranged display panels 120 are used to support the exhibits and divide the display space 110 into multiple spaces. At the same time, the multiple spaces are interconnected through the hollow display panels 120, without affecting the circulation of cold air.
[0022] See also Figure 1 and Figure 2 The circulation channel 200 is arranged around the outside of the exhibition space 110. The circulation channel 200 includes a bottom channel 210, two side channels 220, and a top channel 230. The bottom channel 210 and the top channel 230 are connected by the two side channels 220 to form a U-shaped structure. The bottom channel 210 is located at the bottom and is used to connect to an external cold source to supply cold air into the circulation channel 200. The top channel 230 is located at the top. Cold air flows from the bottom channel 210 through the side channels 220 to the top channel 230, allowing the cold air to be discharged from the top. This changes the traditional bottom-out structure of cold air; the cold air flowing from the top will naturally fall, thus ensuring that the cold air passes through the entire exhibition space. Space 110 is designed to avoid dead corners in the refrigeration system. An upper air inlet 231 is provided between the top channel 230 and the display space 110, and a return outlet 211 is provided between the bottom channel 210 and the display space 110. The return outlet 211 is located at the bottom of the display space 110 to connect the display space 110 and the bottom channel 210, and the upper air inlet 231 is located at the top of the display space 110 to connect the display space 110 and the top channel 230. In other words, after the cold air flows from the bottom channel 210 into the top channel 230 through the side channel 220, it flows back from the top air inlet 231 through the display space 110 to the bottom channel 210, thus achieving overall cold air circulation.
[0023] See also Figure 1The display space 110 is provided with auxiliary air outlets 221 and 222 on both sides, which are connected with the side channels 220. The auxiliary air outlet 221 is provided at the bottom of the display space 110 and the output end is inclined upward. The auxiliary air outlet 222 is provided at the top of the display space 110 and the output end is inclined downward. The auxiliary air outlets 221 and 222 are used for auxiliary air inlet. The output end of the auxiliary air outlet 221 is inclined upward into the display space 110, which is used for the dead angle at the bottom of the display space 110. The output end of the auxiliary air outlet 222 is inclined downward into the display space 110, which is used for the dead angle at the top of the display space 110. The display space 110 is fully covered by cold air.
[0024] Continuing to refer to Figure 1 The upper air inlet 231 is provided with a fan 240. The fan 240 is used to guide the airflow. When the fan 240 is started, the cold air in the top channel 230 can be sucked and sent into the display space 110, so as to effectively control the input amount of cold air. For example, when the temperature in the display space 110 rises, the speed of the fan 240 is increased, that is, the speed of the cold air sent into the display space 110 is increased. When the temperature in the display space 110 tends to be the preset temperature, the speed of the fan 240 is reduced, that is, the speed of the cold air sent into the display space 110 is reduced.
[0025] Figure 3 The structure diagram of the flow guide plate 250 is shown; Figure 4 The back structure diagram of the flow guide plate 250 is shown; Figure 3 、 Figure 4 Combined with Figure 1 The output end of the upper air inlet 231 is provided with a flow guide plate 250. The flow guide plate 250 is uniformly provided with a plurality of groups of flow guide channels 251 around the shaft. The flow guide channels 251 are spiral structures. The cold air can be spirally circulated in the display space 110 by the plurality of spiral flow guide channels 251, which can more fully contact each part of the display space, greatly increase the mixing degree with the air, make the temperature distribution of the entire display area more uniform, effectively avoid the local overheating or overcooling phenomenon, provide a more stable refrigeration environment for the goods, and help to prolong the preservation period of the goods. The radius of the flow guide channel 251 gradually increases along the axial extension direction. With the gradual increase of the radius, the centrifugal force of the airflow gradually decreases, which avoids the airflow from leaving the spiral track due to the excessive centrifugal force, so as to ensure the stable rotation of the airflow and maintain the efficient circulation mode of the rotating airflow. At the same time, the spiral channel with gradually increasing radius provides a larger diffusion space for the airflow. The airflow diffuses in the gradually increasing space, which can more fully exchange heat with the air in the display cabinet, so as to ensure that the goods in the entire display area can be in a more stable and suitable refrigeration temperature environment.
[0026] The above examples are only used to illustrate the technical solutions of the present application, and are not limiting.
