[0034] In the related art, the refrigerator injects the foaming material in a one-shot injection method at the bottom. After the foaming material is ejected from the gun head, it falls on the rear back plate of the box body. The foaming material has a low viscosity and strong fluidity, and gradually begins to flow and fill around. However, if the height of the internal flow channel is less than 20 mm (narrow flow channel) during the flowing process of the foaming material, the foaming material will have difficulty flowing and may even not be filled completely eventually. The present application provides a refrigeration device to solve the above technical problems.

[0035] For the convenience of description and understanding, the direction towards the center of the refrigeration device is defined as the inner direction, and the direction away from the center of the refrigeration device is defined as the outer direction.

[0036] Figure 1 It is a schematic structural view of the refrigeration device of the present utility model.

[0037] Refer to Figure 1 , this embodiment provides a refrigeration device for storing items at low temperature. The refrigeration device can be a refrigerator, a refrigerated display cabinet, a wine cooler, or a refrigerator cabinet. The refrigeration device includes a cabinet 100 and an inner container 200 disposed inside the cabinet 100.

[0038] A refrigeration compartment with an opening at the front side is formed inside the cabinet 100, and food is placed in the refrigeration compartment for low-temperature storage. Specifically, an inner container 200 is disposed inside the cabinet 100, and a refrigeration compartment with an opening at the front side is formed inside the inner container 200, and items are placed in the refrigeration compartment for low-temperature storage of the items. A plurality of inner containers 200 are provided and are spaced apart from each other.

[0039] A door is pivotally attached to the front side of the cabinet 100 to be able to open or close the refrigeration compartment inside the cabinet 100 and to take and place items in the refrigeration compartment. In this embodiment, the door is pivotally attached to the front surface of the cabinet 100 to open and close the refrigeration compartment.

[0040] A refrigeration assembly is used to provide cold air to the space inside the refrigeration compartment to provide cold air to the items inside the refrigeration compartment. The refrigeration assembly transfers the cold air to the air inside the refrigeration air duct, provides cold air to the refrigeration compartment, so that cold air can be obtained inside the refrigeration air duct. The refrigeration air duct can be selectively communicated with the refrigeration compartment to introduce the air inside the refrigeration air duct into the refrigeration compartment to be able to refrigerate the refrigeration compartment.

[0041] There is a gap between the inner container 200 and the cabinet 100, thus forming a foaming cavity 300. The foaming cavity 300 is used to fill the foaming material to form a foaming layer for heat insulation. The foaming material surrounds the outer peripheral side of the inner container 200, thereby insulating the refrigeration compartment and maintaining the temperature of the refrigeration compartment.

[0042] In some embodiments, the door includes a freezer door for covering the freezer compartment and a refrigerator door for covering the refrigerator compartment. The refrigerator door is pivotally attached to the front sides of the refrigerator compartment and the variable-temperature compartment to open and close the refrigerator compartment and the variable-temperature compartment. The freezer door is pivotally attached to the front side of the freezer compartment to open and close the freezer compartment. The freezer door and the refrigerator door are spaced apart in the left-right direction.

[0043] The refrigeration assembly is used to release the heat inside the refrigeration device to the external environment, to provide cold air to the refrigeration compartment to maintain a low-temperature environment inside the refrigeration compartment. The refrigeration assembly includes components such as a compressor, a condenser, an evaporator, and a capillary tube. The compressor, the condenser, the capillary tube, and the evaporator are connected in sequence, and the outlet of the evaporator is connected to the inlet of the compressor, thereby forming a channel for the refrigerant to circulate inside the compressor, the condenser, the capillary tube, and the evaporator.

[0044] The specific structure and connection relationship of the refrigeration assembly refer to the refrigeration assembly in the related art and will not be described in detail here.

[0045] Figure 2 It is a partial structural schematic diagram of the utility model. Figure 3 It is a partial structural schematic diagram of the box body of the utility model.

[0046] See also Figures 1 to 3 In this embodiment, there is a gap between the outer peripheral side of the inner liner 200 and the side wall of the box body 100, thereby forming a foaming cavity 300. An injection port 110 penetrating into the foaming cavity 300 is provided on the outer side surface of the box body 100. The injection port 110 is used for the corresponding structure to pass through, so that the foaming material is injected into the foaming cavity 300 through the injection port 110.

[0047] In this embodiment, the foaming cavity 300 includes a first foaming region 310 close to the injection port 110 and a second foaming region 320 away from the injection port 110 ; the injection port 110 is located on a side of the first foaming region 310 away from the second foaming region 320 .

[0048] The inner container 200 is provided in plurality, and the plurality of inner containers 200 are arranged at intervals. The spacing direction of the inner container 200 is parallel to the first foaming area 310 and the second foaming area 320, and there is a spacing between adjacent inner containers 200.

[0049] In this embodiment, two inner containers 200 are provided, and the two inner containers 200 are arranged at an interval. The two inner containers 200 correspond to the first foaming area 310 and the second foaming area 320 respectively.

[0050] It should be noted that, in this embodiment, there is a gap between the rear side wall of the box body 100 and the rear side wall of the liner 200. The first foaming area 310 and the second foaming area 320 in the figure are respectively arranged between the rear side wall of the liner 200 and the rear side wall of the box body 100.

[0051] In some embodiments, the first foaming area 310 and the second foaming area 320 can be disposed between the left and right sides of the liner 200 and the cabinet 100. In the present application, the up and down, left and right, and front and back directions of the refrigeration device are all referenced to the state of the refrigeration device when in use.

[0052] In the related art, the gap between the outer peripheral side of the inner liner 200 and the side wall of the box 100 forms the foaming cavity 300. The gap between the outer peripheral side of the inner liner 200 and the side wall of the box 100 is small, which is not conducive to the flow of the foaming material, and the foaming material is easy to accumulate in the gap between adjacent inner liner 200.

[0053] In addition, in some refrigeration equipment, an insulation plate or a convex bump is provided on the rear side wall of the box body 100, so that a convex structure is formed on the rear side wall of the box body 100, and the gap of the foaming cavity 300 at this location is small, which is not convenient for the flow of the foaming material. The convex structure can also block the flow of the foaming material.

[0054] In this embodiment, a rearwardly protruding air duct foam is formed on the outer peripheral side of the rear side wall of the inner liner 200, so that the gap of the foaming cavity 300 at this location is small, which is not convenient for the flow of the foaming material.

[0055] Specifically, the arrangement of the heat preservation plate, the convex bump and the air duct foam can form a narrow flow channel area in the foaming cavity 300, which is not convenient for the flow of the foaming material.

[0056] Figure 4 It is a schematic diagram of the connection of the drainage tube of the utility model on the box body.

[0057] See again Figures 1 to 4 The refrigeration device further comprises a drainage pipe 400 , the inlet end of which is connected to the external injection gun head. The drainage pipe 400 is passed through the injection port 110 , and the outlet end of the drainage pipe 400 extends into the foaming cavity 300 .

[0058] The foaming material in the foaming material is injected into the drainage tube 400 through the injection gun head, and the foaming material is injected into the foaming cavity 300 through the drainage tube 400 . The foaming material flows in the foaming cavity 300 to fill the foaming cavity 300 .

[0059] The diameter of the outlet end of the inner cavity of the drainage tube 400 gradually decreases in the direction away from the inlet end, thereby improving the direction in which the foaming material flows out of the outlet end of the drainage tube 400, thereby effectively avoiding the accumulation of the foaming material in the drainage tube 400 and effectively ensuring the flow of the foaming material in the foaming cavity 300.

[0060] The drainage tube 400 is slidably disposed in the injection port 110 so as to be inserted into and withdrawn from the foaming cavity 300. The diameter of the injection port 110 is larger than the outer diameter of the drainage tube 400. The drainage tube 400 has a preset length, and the drainage tube 400 slides so that the outlet end of the drainage tube 400 can be moved to different positions in the foaming material, so that the foaming material can be injected into different positions in the foaming cavity 300 to ensure uniformity of the foaming material injected into the foaming cavity 300.

[0061] An injection molding cover 120 is provided on the inner side of the box body 100 near the injection molding port 110; the upper end of the injection molding cover 120 is hinged on the box body 100, so that after the drainage tube 400 is pulled out of the foaming cavity 300, the injection molding cover 120 can cover the injection molding port 110, thereby blocking the injection molding port 110 and sealing the foaming material in the box body 100.

[0062] In this embodiment, the upper end of the injection molded cover 120 is hinged to the box body 100. After the drainage tube 400 is withdrawn, under the action of gravity, the injection molded cover 120 automatically rotates downward, so as to cover the injection port 110 of the box body 100. Further, a pull rope is provided on the injection molded cover 120 to be able to pull the injection molded cover 120 to close the injection port 110.

[0063] In some embodiments, the injection molded cover 120 is arranged on the outer side surface of the box body 100, and the injection molded cover 120 is rotatably or detachably connected to the box body 100.

[0064] Figure 5 It is a schematic structural view of the first embodiment of the flow guiding member of the present utility model.

[0065] Refer to Figures 1 to 5 , the refrigeration device further includes a flow guiding member 500. The drainage tube is fixed on the box body 100 and is located in the foaming cavity 300 for guiding and flowing of the foaming material in the foaming cavity 300.

[0066] The flow guiding member 500 is formed with a flow guiding channel 510. The two ends of the flow guiding channel 510 are respectively communicated with the first foaming area 310 and the second foaming area 320. A flow guiding channel 510 is arranged in the foaming cavity 300; the two ends of the flow guiding channel 510 are respectively communicated with the first foaming area 310 and the second foaming area 320, and the outlet end of the drainage tube 400 can extend into the flow guiding channel 510, so that the foaming material in the drainage tube 400 can be conveyed to the second foaming area 320 through the flow guiding channel 510.

[0067] The second foaming area 320 is arranged far away from the injection port 110. The arrangement of the flow guiding channel 510 enables the foaming material to be directly conveyed to the second foaming area 320 through the flow guiding channel 510, effectively avoiding the accumulation of the foaming material in the first foaming area 310.

[0068] In this embodiment, the spacing direction of the inner liner 200 is parallel to the spacing direction of the first foaming area 310 and the second foaming area 320; the two ends of the flow guiding channel 510 respectively extend into the gaps between the two inner liners 200 and the box body 100, so as to effectively avoid the accumulation of the foaming material in the space between the two inner liners 200.

[0069] In this embodiment, the flow guiding member 500 includes a bottom plate 520 and wing plates 530 vertically connected to the edges of the bottom plate 520; the bottom plate 520 is attached to the inner side surface of the box body 100; there are two wing plates 530, and the two wing plates 530 are arranged at intervals and are arranged on two opposite edges of the bottom plate 520; the two wing plates 530 and the bottom plate 520 enclose to form the flow guiding channel 510.

[0070] In this embodiment, a step 540 is recessed downward on the side of the wing plate 530 facing away from the bottom plate 520. The step 540 is provided at one end of the flow guide member 500 facing away from the injection port 110, and the edge of the step 540 abuts against the outer side surface of the inner container 200. The step 540 abuts against the inner container 200, so that the flow guide member 500 can not only play a role in guiding the flow, but also play a role in supporting the inner container 200.

[0071] In this embodiment, a wind channel foam protruding backward is formed on the outer peripheral side of the rear side wall of the inner container 200, and the step 540 abuts against the wind channel foam.

[0072] Figure 6 It is a schematic structural diagram of the second embodiment of the flow guide member of the present utility model.

[0073] Refer to Figures 1 to 6 , the flow guide member 500 includes a bottom plate 520 and wing plates 530 vertically connected to the edges of the bottom plate 520; the bottom plate 520 is attached to the inner side surface of the box body 100; two wing plates 530 are provided, the two wing plates 530 are spaced apart and are provided on two opposite edges of the bottom plate 520; the two wing plates 530 and the bottom plate 520 enclose a flow guide channel 510.

[0074] In this embodiment, the distance between the ends of the two wing plates 530 facing away from the injection port 110 gradually increases in the direction away from the injection port 110. The end of the flow guide cavity facing away from the injection is of a flared structure, so that the flow range of the foaming material in the flow guide channel 510 is wider, so that it can flow in multiple directions, so that the flow of the injection molding material is more uniform.

[0075] Figure 7 It is a schematic structural diagram of the third embodiment of the flow guide member of the present utility model. Figure 8 It is a schematic cross-sectional view of the third embodiment of the flow guide member of the present utility model.

[0076] Refer to Figures 1 to 8 , the flow guide member 500 includes a bottom plate 520 and wing plates 530 vertically connected to the edges of the bottom plate 520; the bottom plate 520 is attached to the inner side surface of the box body 100; two wing plates 530 are provided, the two wing plates 530 are spaced apart and are provided on two opposite edges of the bottom plate 520; the two wing plates 530 and the bottom plate 520 enclose a flow guide channel 510.

[0077] In this embodiment, the surface of the bottom plate 520 facing the inner container 200 is inclined toward the box body 100 in the direction toward the second foaming area 320 to facilitate the flow of the foaming material.

[0078] Refer to again Figures 1 to 8, on one side of the wing plate 530 facing the injection port 110, there is an inclined hypotenuse 550 which extends in a direction away from the injection port 110 in the direction of the back of the bottom plate 520. This facilitates the setting of the flow guide member 500 in the space between the inner container 200 and the box body 100.

[0079] It should be noted that in some embodiments, the flow guide member 500 is not provided in the box body 100, and convex ribs are formed on the inner side surface of the box body 100; the convex ribs extend in a straight line and are arranged between the first foaming area 310 and the second foaming area 320. A channel penetrating through the first foaming area 310 and the second foaming area 320 is formed on the convex ribs, thus forming the flow guide channel 510.

[0080] Based on the above structure, when foaming the box body 100, the drainage pipe 400 passes through the injection port 110 and jacks up the injection cover 120. The outlet end of the drainage pipe 400 extends into the flow guide channel 510, and the foaming material passes through the injection gun head and the drainage pipe 400 and is discharged into the flow guide channel 510. The foaming material in the flow guide channel 510 flows towards the second foaming area 320. After injecting the foaming material into the flow guide channel 510 for a preset time, the second foaming area 320 is filled with the foaming material. Move the drainage pipe 400 so that the drainage pipe 400 is withdrawn from the flow guide channel 510 and the outlet end of the drainage pipe 400 is located in the first foaming area 310, and then inject the foaming material into the first foaming area 310. After injecting the foaming material into the first foaming area 310 for a preset time, the first foaming area 310 is filled with the foaming material, and then the drainage pipe 400 is withdrawn from the injection port 110. The injection cover 120 is closed and covers the injection port 110 to prevent the foaming material from flowing out of the box body 100, thus completing the injection of the foaming material into the box body 100.

[0081] In the present utility model, an injection port 110 penetrating through to the foaming cavity 300 is provided on the outer side surface of the box body 100. The foaming cavity 300 includes a first foaming area 310 close to the injection port 110 and a second foaming area 320 far from the injection port 110; the injection port 110 is located on the side of the first foaming area 310 facing away from the second foaming area 320. A diversion channel 510 is arranged in the foaming cavity 300; both ends of the diversion channel 510 are respectively communicated with the first foaming area 310 and the second foaming area 320. A drainage pipe 400 is inserted into the injection port 110, the inlet end of the drainage pipe 400 is connected to an external injection gun head, and the outlet end of the drainage pipe 400 can extend into the diversion channel 510. Through the diversion channel 510 and the arrangement of the drainage pipe 400 in the diversion channel 510, the foaming material in the drainage pipe 400 can be filled towards the second foaming area 320 through the diversion channel 510, thereby avoiding the accumulation of the foaming material at the injection port 110 or the drainage pipe 400, facilitating the flow of the foaming material in the foaming cavity 300, effectively ensuring the uniform filling of the foaming material in the foaming cavity 300, and ensuring the heat preservation performance of the foaming layer formed by the foaming material.
