[0035] Figure 1 It is a schematic structural diagram of the refrigerator of the present utility model. Figure 2 It is a schematic cross-sectional structural diagram of the refrigerator of the present utility model.

[0036] Refer to Figure 1 and Figure 2 , this embodiment provides a refrigerator for storing items at low temperature. The refrigerator can be a refrigerated display cabinet, a wine cooler, or a refrigerator. The refrigeration device includes a cabinet 100 and an inner liner 200 disposed within the cabinet 100.

[0037] A refrigerating compartment with an opening at the front side is formed within the cabinet 100, and food is placed in the refrigerating compartment for low-temperature storage. Specifically, an inner liner 200 is provided within the cabinet 100, and a refrigerating compartment with an opening at the front side is formed within the inner liner 200, and items are placed in the refrigerating compartment for low-temperature storage of the items. A plurality of inner liners 200 are provided and are spaced apart from each other.

[0038] A door is pivotally attached to the front side of the cabinet 100 to open or close the refrigerating compartment within the cabinet 100, and items can be taken and placed in the refrigerating compartment. In this embodiment, the door is pivotally attached to the front side of the cabinet 100 to open and close the refrigerating compartment.

[0039] The refrigeration assembly is used to provide cold air to the space within the refrigerating compartment to provide cold air to the items within the refrigerating compartment. The refrigeration assembly transfers the cold air to the air within the refrigeration duct, provides cold air to the refrigerating compartment, so that cold air can be obtained within the refrigeration duct. The refrigeration duct can selectively communicate with the refrigerating compartment to introduce the air within the refrigeration duct into the refrigerating compartment to refrigerate the refrigerating compartment.

[0040] A gap is formed between the inner liner 200 and the cabinet 100 to form a foaming cavity 210. The foaming cavity 210 is used to fill with foaming material to form a foaming layer for heat insulation. The foaming material surrounds the outer peripheral side of the inner liner 200, thereby insulating the refrigerating compartment and maintaining the temperature of the refrigerating compartment.

[0041] 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.

[0042] The refrigeration assembly is used to release the heat within the refrigeration device to the external environment, provide cold air to the refrigerating compartment, and maintain a low-temperature environment within the refrigerating 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 within the compressor, the condenser, the capillary tube, and the evaporator.

[0043] The specific structure and connection relationship of the refrigeration component refer to the refrigeration component in the related art, which will not be elaborated here.

[0044] The box body 100 includes opposite first side wall 101 and second side wall 102. In this embodiment, the state when the box body 100 is placed upright is taken as a reference. The side wall at the bottom is the first side wall 101, and the top side wall is the second side wall 102.

[0045] In some embodiments, the side wall at the bottom is the second side wall 102, and the top side wall is the third side wall.

[0046] Taking the state when the box body 100 is placed upright as a reference, the front side opening of the inner container 200 forms a refrigeration compartment; a foaming cavity 210 is formed between the rear side wall of the inner container 200 and the box body 100.

[0047] In some embodiments, there are intervals between the top and bottom of the inner container 200 and the box body 100 respectively, thus forming the foaming cavity 210.

[0048] In another embodiment, there are intervals between the left and right sides of the inner container 200 and the box body 100, forming the foaming cavity 210.

[0049] Figure 3 It is a schematic diagram of the first side wall surface of the refrigerator of the present utility model. Figure 4 It is a schematic diagram of the rear side of the refrigerator of the present utility model.

[0050] Refer to Figures 1 to 4 , a material injection port 220 penetrating into the foaming cavity 210 is provided on the outer side surface of the first side wall 101. The size of the material injection port 220 is set such that a foaming gun can inject foaming material into the foaming cavity 210, so as to form a foaming layer between the box body 100 and the inner container 200.

[0051] The material injection port 220 is provided on the first side wall 101 and is directly opposite to the foaming cavity 210. The material injection port 220 is provided at the rear end of the first side wall 101.

[0052] In this embodiment, the material injection port 220 is located in the middle of the first side wall 101 in the left - right direction. In some embodiments, the material injection port 220 is arranged deviating from the middle of the first side wall 101 in the left - right direction.

[0053] Figure 5 It is a schematic diagram of the flow of the foaming material in the foaming cavity of the present utility model. Figure 6 It is another schematic diagram of the flow of the foaming material in the foaming cavity of the present utility model. Figure 7 It is a schematic structural diagram of the diversion pipe of the present utility model.

[0054] Refer to Figures 1 to 7, the refrigerator may further include a diversion pipe 300 disposed in the foaming cavity 210 for guiding the flow direction of the foaming material within the foaming cavity 210.

[0055] The diversion pipe 300 is disposed in the foaming cavity 210. The diversion pipe 300 has a hollow pipe structure, and a diversion cavity for guiding the flow is formed therein. The diversion pipe 300 includes a relative feed end 301 and a discharge end 302. The foaming material enters the diversion pipe 300 from the feed end 301 so as to be able to move toward the discharge end 302 within the diversion cavity of the diversion pipe 300, and thus is discharged from the diversion pipe 300 at the discharge end 302.

[0056] The feed end 301 of the diversion pipe 300 faces the injection port 220 so that the injection gun can inject the foaming material into the diversion cavity; the discharge end 302 of the diversion pipe 300 is close to the second side wall 102 and has a gap therebetween. Thus, the foaming material in the injection gun can flow through the diversion cavity of the diversion pipe 300 to a position in the foaming cavity 210 close to the second side wall 102. Through the diversion pipe 300, the foaming material can be directly introduced into the foaming cavity 210 of the box body 100 close to the second side wall 102. After the foaming cavity 210 at the second side wall 102 of the box body 100 is filled, it then flows back to the second side wall 102 of the box body 100, thereby avoiding uneven filling or empty package phenomena and improving the heat preservation effect.

[0057] The discharge end 302 of the diversion pipe 300 is close to the second side wall 102 and has a gap therebetween, which can effectively prevent the foaming material from being blocked at the first side wall 101 after coming out of the discharge end 302 of the diversion cavity and can flow at the first side wall 101.

[0058] In this embodiment, the distance between the feed port of the diversion pipe 300 and the first side wall 101 is less than or equal to 500 mm. During the injection process, the injection gun is disposed at the injection port. By injecting the foaming material into the diversion pipe, in order to ensure the pressure of the foaming material in the diversion cavity, the distance between the feed port of the diversion pipe 300 and the first side wall 101 is less than or equal to 500 mm.

[0059] In some embodiments, the distance between the feed port of the diversion pipe 300 and the first side wall 101 may be greater than 500 mm.

[0060] The diversion pipe 300 extends in a straight line, and the extension line of the extending direction of the diversion pipe 300 passes through the injection port 220 so that the diversion pipe 300 and the injection port 220 are on the same straight line, thereby facilitating the injection of the foaming material from the injection port into the diversion cavity.

[0061] In this embodiment, the distance between the cabinet 100 and the inner liner 200 is 45 - 60 mm. The gap between the inner liner 200 and the cabinet 100 is small, so that the thickness of the foaming cavity 210 is small, and thus the refrigerating compartment has a larger space.

[0062] The distance between the end of the discharge port facing the second side wall 102 and the second side wall 102 is greater than the distance between the cabinet 100 and the inner liner 200, so as to effectively ensure that the foaming material can fill the gap between the second side wall 102 and the cabinet 100.

[0063] In this embodiment, the flow guide pipe is arranged in the middle of the cabinet 100 in the left - right direction, and the injection port 220 is arranged in the middle of the cabinet 100 in the left - right direction so that the flow guide pipe corresponds to the injection port. It can also ensure that the foaming material flowing back from the discharge end 302 of the flow guide pipe 300 towards the first side wall 101 is uniform on both sides of the flow guide pipe 300, so that the filling of the foaming material in the refrigerator is more uniform.

[0064] In some embodiments, the extension line of the extending direction of the flow guide pipe 300 passes through the injection port 220 so that the flow guide pipe 300 and the injection port 220 are on the same straight line. The flow guide pipe 300 and the injection port 220 both deviate from the middle of the cabinet 100 in the left - right direction.

[0065] One end of the flow guide cavity towards the inlet expands outwards to form an expansion cavity 310; the foaming material in the injection gun is discharged from the outlet of the injection gun and sprayed into the expansion cavity 310. The expansion cavity 310 expands outwards relative to the flow guide cavity, so that the expansion cavity 310 has a larger space relative to the flow guide cavity. The foaming material injected into the expansion cavity 310 from the injection port 220 will not be blocked in the expansion cavity 310, effectively ensuring the flow of the foaming material in the flow guide cavity, and ensuring that the foaming material can converge in the expansion cavity, so that the converged foaming material can be evenly extruded with each other, and there is sufficient foaming material flowing after converging in the expansion cavity 310 to ensure the uniform flow of the foaming material in the flow guide cavity.

[0066] In this embodiment, the expansion cavity 310 expands outwards in the left - right direction, so that the internal size of the expansion cavity 310 increases. And the expansion cavity 310 does not extend in the front - back direction to avoid the front side of the flow guide pipe 300 abutting against the inner liner 200, effectively ensuring that there is a space for filling the foaming material between the rear side surface of the inner liner 200 and the flow guide pipe 300, and thus effectively ensuring the heat preservation performance of the inner liner 200.

[0067] The diversion tube 300 includes two spaced diversion plates 320 which extend along the extension direction of the diversion tube 300; the diversion plates 320 include a diversion section 321 and a flaring section 322 in the extension direction. The flaring section 322 is arranged at one end of the diversion section 321 facing the first side wall 101; the two flaring sections 322 extend away from each other in the direction facing the first side wall and then extend parallel to each other, and a flaring cavity 310 is formed between the two flaring sections 322.

[0068] In this embodiment, the two flaring sections 322 extend away from each other in the direction facing the first side wall, that is, the distance between the two flaring sections 322 gradually increases in the direction facing the first side wall. Thereby, the flaring section 322 has a smooth transition at the end facing the diversion section 321, so that the foaming material in the flaring cavity 310 can flow towards the discharge end 302 of the diversion tube 300, avoiding blockage of the foaming material in the flaring cavity 310.

[0069] A stop baffle 330 is arranged at the inlet end 301 of the diversion tube 300, and one end of the stop baffle 330 is connected to the side wall of the diversion tube 300; the stop baffle 330 is inclined in the direction from the side wall of the diversion tube 300 towards the center line of the diversion tube 300 along the direction towards the discharge end 302. The arrangement of the stop baffle 330 can effectively prevent the foaming material from flowing out of the inlet, and effectively ensure that the foaming material flows out of the outlet of the diversion tube 300.

[0070] In this embodiment, two opposite stop baffles 330 are arranged at the inlet end 301 of the diversion tube 300, and the two stop baffles 330 approach each other; an inlet is formed between the two stop baffles 330. The stop baffle 330 is formed on the flaring section 322 of the diversion plate 320.

[0071] In some embodiments, a stop baffle 330 is arranged at the inlet end 301 of the diversion tube 300.

[0072] In this embodiment, the diversion section 321 can extend in a straight line, and the diversion cavity is a constant-area flow channel for the diversion section 321.

[0073] In some embodiments, the distance between the two ends of the diversion section 321 facing the second side wall 102 gradually increases in the direction facing the second side wall 102, so that the diversion cavity is an expanding flow channel in the direction facing the second side wall 102, thereby facilitating the foaming material discharged from the discharge end 302 of the diversion tube 300 to diffuse outward, so as to facilitate the filling of the foaming material in different directions in the foaming cavity 210.

[0074] The outer side of the diversion tube 300 includes an opposite fitting surface and an overflow surface; the fitting surface of the diversion tube 300 is fitted to the box body 100, and there is a gap between the overflow surface and the inner container 200; an overflow hole penetrating through to the diversion cavity is formed in the overflow surface of the diversion tube 300. There is a gap between the overflow surface and the inner container 200 for the foaming material to fill. An overflow hole penetrating through to the diversion cavity is formed in the overflow surface of the diversion tube 300, and the foaming material can be discharged from the overflow hole and fill the gap between the overflow surface and the inner container 200.

[0075] The overflow hole has a structure such as a circle, a square or a rectangle, so that part of the foaming material can penetrate through the small hole and fill the gap between the diversion tube 300 and the inner container 200;

[0076] In this embodiment, the diversion tube 300 is clamped or pasted on the box body 100. The material of the diversion tube 300 is a non-metallic flexible material, which can be a pet film or a puc tube material.

[0077] The width of the inner container 200 is H, and the width of the diversion cavity is D, where D=(0.2-0.4)H to ensure the diversion effect of the diversion cavity.

[0078] In this embodiment, the width of the diversion tube 300 in the left-right direction is 110 mm - 130 mm to ensure the flow of the foaming material in the diversion tube 300 and the diversion effect.

[0079] In some embodiments, the width of the diversion tube 300 in the left-right direction is less than 110 mm. In some embodiments, the width of the diversion tube 300 in the left-right direction is greater than 110 mm.
