Since the pouring pipe is cylindrical, the pouring outlet of the pouring pipe is easy to accumulate foaming material, thereby affecting the foaming material to enter the front section of the cabinet, and greatly affecting the foaming quality. In addition, the pouring pipe is very short, so that the foaming material is more difficult to advance to the front section of the cabinet.

[0034] The present application will be described in detail below with reference to the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and the structural, method, or functional changes made by those of ordinary skill in the art based on these embodiments are included in the protection scope of the present application.

[0036] As Figures 1 to 9 shown, the first embodiment provided by the present application discloses a refrigerator, which includes a cabinet and a door body connected to the cabinet, the cabinet defines a storage space, and the door body can be operated to open or close at least part of the storage space. Wherein, the storage space can include a plurality of storage compartments, and the number and structural form of the storage compartments can be configured according to different requirements.

[0037] The cabinet includes a shell 10 and an inner container 12 arranged in the shell 10, and the shell 10 and the inner container 12 define a foaming space, which is used to accommodate foaming material to achieve the purpose of heat preservation in the inner container 12. Wherein, the refrigerator further includes an injection device 13 located at least partially in the foaming space, the injection device 13 has an injection port 18 and a discharge port 20, and the injection device 13 is provided with an inclined portion 30 at one end adjacent to the injection port 15, and the outer periphery diameter of the inclined portion 30 gradually decreases from one end closer to the injection port 18 to one end away from the injection port 18.

[0038] Generally, a vacuum VIP plate is arranged between the shell 10 and the inner container 12, and the inclined portion 30 of the material injection device 13 can provide installation space for the vacuum VIP plate.

[0039] Specifically, the material injection device 13 comprises a feeding pipe 32 and a material injection pipe 22 connected with the feeding pipe 32 and in communication with the feeding pipe 32, and the material injection port 18 and the inclined portion 30 are arranged on the feeding pipe 32. In the preferred embodiment, the feeding pipe 32 and the material injection pipe 22 are manufactured independently, and then the feeding pipe 32 and the material injection pipe 22 are connected, and specifically, the feeding pipe 32 and the material injection pipe 22 are detachably connected. In this way, the feeding pipe 32 and the material injection pipe 22 are convenient to manufacture, and the mold is simple, thereby reducing the manufacturing cost of the feeding pipe 32 and the material injection pipe 22. Of course, the feeding pipe 32 and the material injection pipe 22 can also be integrally formed.

[0040] The material injection port 18 comprises a semicircular portion 34 and a square portion 36 tangent to the semicircular portion 34. The feeding pipe 32 is snap-connected with the material injection pipe 22, and of course, other connection modes such as welding and bonding can also be used between the material injection pipe 22 and the material outlet 24. The inclined portion 30 is arranged on the feeding pipe 32, and the feeding pipe 32 has a butt joint portion 38 connected with the material injection pipe 22, the cross-sectional shape of the butt joint portion 38 is the same as that of the material injection pipe 22, the outer circumferential diameter of the butt joint portion 38 is smaller than that of the material injection pipe 22, and the butt joint portion 38 is located in the material injection pipe 22. Specifically, the cross section of the butt joint portion 38 is also semicircular.

[0041] The material injection pipe 22 extends along the same cross section in the longitudinal direction, and the material injection pipe 22 comprises a bottom flat portion 40 abutting against the shell 10 or the inner container 12. In this way, the material injection pipe 22 can be more stably supported on the shell 10 or the inner container 12.

[0042] Further, the material injection pipe 22 further comprises a circular arc portion 42 opposite to and connected with the bottom flat portion 40. Preferably, the circular arc portion 42 is semicircular, that is, the material injection pipe 22 is a semicircular pipe extending in the longitudinal direction.

[0043] One of the abutting part 38 and the injection tube 22 is provided with a clamping groove 44, and the other one is provided with a clamping protrusion 46 matched with the clamping groove 44. In this embodiment, the clamping protrusion 46 is arranged on the abutting part 38, and the clamping groove 44 is arranged on the injection tube 22. Of course, the clamping protrusion 46 can also be arranged on the injection tube 22, and the clamping groove 44 is arranged on the abutting part 38 correspondingly. The feeding tube 32, the injection tube 22 and the discharging part 24 are all plastic parts, and of course, the feeding tube 32, the injection tube 22 and the discharging part 24 can also be made of other materials. Preferably, the clamping protrusion 46 is arranged on the bottom flat surface of the abutting part 38, and the clamping groove 44 is arranged on the bottom flat surface 40 of the injection tube 22 correspondingly, so that the connection between the feeding tube 32 and the injection tube 22 is more stable and reliable.

[0044] In order to make the assembly of the feeding tube 32 and the injection tube 22 more convenient and reliable, the abutting part 38 is provided with a stop part 47 extending outwardly adjacent to the outer periphery of the inclined part 30. When the feeding tube 32 and the injection tube 22 are assembled, the abutting part 38 is placed in the injection tube 22 and is pushed inwardly until it cannot be pushed any more, and at this time, the injection tube 22 abuts against the stop part 47, and the clamping protrusion 46 is matched with the clamping groove 44.

[0045] The injection device 13 also comprises a discharging part 24 connected and communicated with the injection tube 22, and the feeding tube 32 and the discharging part 24 are respectively connected to the opposite ends of the injection tube 22, and the discharge port 20 is arranged on the discharging part 24. In this embodiment, the feeding tube 32, the injection tube 22 and the discharging part 24 are all rigid.

[0046] In this preferred embodiment, the injection tube 22 and the discharging part 24 are manufactured independently, and then the injection tube 22 and the discharging part 24 are connected. In this way, the injection tube 22 and the discharging part 24 are convenient to manufacture, and the mold is simple, so that the manufacturing cost of the injection tube 22 and the discharging part 24 is reduced. Of course, the injection tube 22 and the discharging part 24 can also be integrally formed.

[0047] Specifically, the discharging part 24 gradually increases in diameter from the part close to the injection tube 22 to the outer periphery of the end of the discharging part 24, so as to form a gradually enlarged discharge port.

[0048] In this preferred embodiment, the discharge port 20 is arranged in the form of gradually enlarged structure, so as to play a role of dispersing the foaming material, reduce the injection density, reduce the foaming pressure, prevent the foaming material from accumulating, and greatly improve the foaming quality. Of course, the discharge port can also not be arranged in the form of gradually enlarged structure, which will be described in detail in the following embodiments.

[0049] Preferably, the discharge port 20 is provided in a horn shape. Of course, the discharge port 20 can also be provided in other structural shapes, and is preferably provided in a gradually increasing structural form. In addition, it can also be provided in a semicircular shape or a square shape, etc.

[0050] In the preferred embodiment, the injection tube 22 and the discharge member 24 are detachably connected. Specifically, the injection tube 22 and the discharge member 24 are connected by a buckle connection. Of course, the injection tube 22 and the discharge member 24 can also be connected by other connection methods, such as welding, adhesion, etc. The discharge member 24 has a connecting portion 26 connected to the injection tube 22 and a discharge portion 16, and the horn-shaped discharge port 20 is provided on the discharge portion 16. Part of the connecting portion 26 surrounds part of the outer periphery of the injection tube 22. In this way, the connection between the discharge member 24 and the injection tube 22 is more reliable. The inner side of the connecting portion 26 and the inner side of the discharge portion 16 form an inner recess 28, the injection tube 22 is located in the inner recess 28, and the inner surface of the injection tube 22 to the inner surface of the discharge portion 16 adjacent to the part of the injection tube 22 is smoothly transitioned, and preferably, the inner surface of the injection tube 22 to the inner surface of the discharge portion 16 adjacent to the part of the injection tube 22 is consistent. In this way, the flow of the foaming material from the injection tube 22 to the discharge member 24 is smoother and will not be stuck.

[0051] The injection device 13 also includes a sealing cover 48 for sealing the injection port 18. When an external force acts on the sealing cover 48, the sealing cover 48 can be driven to open the injection port 18, and when the external force is removed, the sealing cover 48 returns to the position of sealing the injection port 18.

[0052] Specifically, in the embodiment, the sealing cover 48 is an elastic sheet with a certain elasticity, and the elastic sheet is provided on the injection tube 32 to cover the injection port 18. The connection between the elastic sheet and the injection tube 32 can be adhesion, buckle connection or welding, etc. Of course, other connection methods can also be used between the elastic sheet and the injection tube 32. Corresponding to the shape of the injection port 18, the elastic sheet has an upper semicircular portion and a lower square portion connected to both ends of the upper semicircular portion. In this way, the elastic sheet is easy to flip.

[0053] The length of the injection tube 22 can be adjusted according to the specific design needs, thereby meeting the needs of different drop point distances during foaming.

[0054] The shell 10 includes a bottom 50 and a top 52. The inlet 18 is closer to the bottom 50 than the outlet 20, meaning that during injection, the foaming material flows from the bottom 50 towards the top 52. The inner liner 12 includes a refrigerated inner liner 58 and a frozen inner liner 56, which are spaced apart and form a central beam 54. A shielding device (not shown) is provided at the central beam 54. The length of the injection device 13 in its extension direction is greater than half the height of the frozen inner liner but less than the height of the frozen inner liner. Therefore, during the injection and foaming process, the foaming material will not directly enter the interior of the central beam 54, thus preventing the foam density inside the central beam 54 from becoming too high and ensuring a relatively uniform density of the foaming material throughout the foaming process.

[0055] Furthermore, since the freezer inner liner 56 and the refrigerator inner liner 58 are distributed vertically, the central beam 54 is arranged horizontally, and the shielding device is also arranged horizontally and fixed between the freezer inner liner 56 and the refrigerator inner liner 58. Moreover, the shielding device extends in an arc shape in the longitudinal direction and protrudes towards the shell 10.

[0056] The injection device 13 is provided with an overflow hole (not shown) to prevent damage to the injection device 13 due to excessive pressure during the foaming process. The position of the overflow hole is not limited, but preferably, in the longitudinal extension direction of the injection device 13, the overflow hole is located in the middle of the injection device 13 or closer to the front section of the injection port 18. In this preferred embodiment, the overflow hole is located on the injection pipe 22.

[0057] During injection, the injection nozzle is aligned with the injection port 18. As the injection nozzle advances, the elastic plate flips inward, allowing the injection nozzle to enter the injection device 13. Once the nozzle reaches the appropriate position, the injection stops, and the foaming liquid flows along the inner wall of the injection device 13 into the space between the shell 10 and the inner liner 12. After injection is complete...

[0058] As the injection nozzle moves outward, the elastic sheet returns to its original position to seal the injection port 18. In this preferred embodiment, the upper part of the injection port 18 is semi-circular, and the lower part is square, which facilitates the inward turning of the elastic sheet. Preferably, the elastic sheet is made of alloy steel. Of course, the elastic sheet can also be made of other materials with a certain deformation recovery function.

[0059] like Figures 10 to 15 As shown, in the second preferred embodiment of the present invention, the injection device 59 includes a feed pipe 60 and a guide pipe 62 connected to the feed pipe 60, with an inclined portion 64 disposed on the feed pipe 60. The feed pipe 60 and the sealing cap 66 are identical in form to those in the first embodiment, and will not be described in detail here. The difference from the first embodiment is that the injection device 59 is configured as two interconnected sections.

[0060] Specific to the preferred embodiment, the material guiding pipe 62 connected with the feeding pipe 60 is arranged as a flexible material guiding pipe. Of course, the material guiding pipe 62 can also be arranged as a rigid material guiding pipe with certain rigidity. Since the material guiding pipe 62 is arranged as a flexible material guiding pipe, when the material is injected, the material guiding pipe 62 can be self-adapted according to the space shape between the shell 68 and the inner container 70, and is not afraid of the interference between the material guiding pipe 62 and other structures between the shell 68 and the inner container 70. The material guiding pipe 62 can be adaptively deformed according to the space shape between the shell 68 and the inner container 70, thereby greatly improving the application range of the material injection device 59, and avoiding the interference of the material guiding pipe 62 by other structures between the shell 68 and the inner container 70.

[0061] In addition, the feeding pipe 60 and the material guiding pipe 62 are independently manufactured, and then the feeding pipe 60 and the material guiding pipe 62 are connected. In this way, the feeding pipe 60 and the material guiding pipe 62 are convenient to manufacture, and the mold is simple, thereby reducing the manufacturing cost of the feeding pipe 60 and the material guiding pipe 62.

[0062] The connection mode between the material guiding pipe 62 and the feeding pipe 60 can be gluing, binding with a tape, etc. Among them, the wall thickness of the material guiding pipe 62 is between 50um and 100um.

[0063] Further, the material guiding pipe 62 has a connecting portion 72 connected with the feeding pipe 60 and a terminal end away from the feeding pipe 60. The outer circumferential diameter of the material guiding pipe 62 gradually increases from the portion close to the connecting portion 72 to the terminal end direction, so as to form a gradually enlarged material outlet 74. In this way, the effect of dispersing the foaming material can be achieved, the injection density is reduced, the foaming pressure is reduced, thereby preventing the accumulation of the foaming material, and greatly improving the foaming quality.

[0064] Preferably, the material outlet 74 is arranged as a horn shape. Of course, the material outlet 74 can also be arranged as other shapes, as long as the outer circumferential diameter gradually increases from the portion close to the connecting portion 72 to the terminal end direction, and the effect of dispersing the foaming material can be achieved.

[0065] The material guiding pipe 62 further includes a material outlet portion 76 connected with the connecting portion 72. When the material is injected, the material guiding pipe 62 is in an open state. At this time, the material outlet portion 76 has an upper surface and a lower surface which are parallel to each other, and a left surface and a right surface which form a certain angle. The upper surface, the left surface, the lower surface and the right surface are sequentially connected. Further, when the material guiding pipe 62 is in the open state, the angle between the left surface and the right surface is an acute angle. The lower surface is a plane which can be supported on the inner container 70. Of course, the material outlet portion 76 of the material guiding pipe 62 can also be arranged as other shapes.

[0066] Preferably, the material of the material guiding pipe 62 is nylon, polyurethane or PE. Of course, the material of the material guiding pipe 62 is not limited to the above materials, and the material guiding pipe 62 can also be made of other materials with certain flexibility.

[0067] Furthermore, before foaming, the guide tube 62 is fixed to the inner liner 70 along its extension direction to prevent folding and thus avoid obstruction during foaming. Specifically, in this embodiment, the guide tube 62 is fixed to the inner liner 70 with adhesive or clips before foaming. Of course, other fixing methods can also be used to fix the guide tube 62 to the inner liner 70.

[0068] The length of the feed tube 62 can be adjusted according to specific design requirements to meet the needs of different drop point distances during foaming.

[0069] The injection device 59 is provided with an overflow hole (not shown) to prevent damage to the injection device 59 due to excessive pressure during the foaming process. The location of the overflow hole is not limited, but preferably, in the longitudinal extension direction of the injection device 59, the overflow hole is located in the middle of the injection device 59 or in the front section closer to the injection port 15. Further, the overflow hole is provided on the guide pipe 62, and the overflow hole is located in the section of the guide pipe 62 that is closer to the feed pipe 60.

[0070] During injection, the injection nozzle (not shown) is aligned with the injection port 15. As the nozzle is advanced, the elastic plate flips inward, allowing the nozzle to enter the injection device 59. Once the nozzle reaches the appropriate position, it stops, and the foaming liquid enters through the inner wall of the injection device 59. As the foaming liquid enters, the guide tube 62 is supported, dispersing the foaming liquid between the shell 68 and the inner liner 70. After injection, the nozzle moves outward, and as it is withdrawn, the elastic plate returns to its original position to seal the injection port 15.

[0071] The feed pipe 60 has a connecting portion that connects to the guide pipe 62, and the cross-sectional shape of the connecting portion is semi-circular. The connecting portion 72 of the guide pipe 62 is sleeved on the outside of the connecting portion.

[0072] like Figures 16 to 17 As shown, the third preferred embodiment of the present invention, like the second embodiment, also has a two-section injection device 77. Specifically, the injection device 77 includes an inlet pipe 78 and a guide pipe 80 connected to the inlet pipe 78. The inlet pipe 78 is the same as in the first embodiment, and it also has an inclined portion. The forms of the inlet pipe 78 and the sealing cap 81 are exactly the same as in the first embodiment, and will not be described in detail here. The difference from the second embodiment is the shape of the guide pipe 80.

[0073] In this embodiment, the feed tube 80 is a rigid feed tube with a certain degree of rigidity. That is, the feed tube 80 maintains the same shape whether or not it is filled with material. Specifically, the feed tube 80 extends along the same cross-section in its longitudinal direction, and the outlet 82 is located on the feed tube 80. Therefore, in this embodiment, the outlet is not flared. The cross-section of the feed tube 80 is set to semi-circular. Of course, the cross-section of the feed tube 80 can also be set to other shapes.

[0074] Furthermore, the inner liner 84 is also provided with a support member 86, which is used to support the guide tube 80. There is a certain gap between the guide tube 80 and the inner liner, so that the guide tube 80 will not directly contact the inner liner 84. The lower surface of the guide tube 80 abuts against the support member 86.

[0075] like Figure 18 As shown, the fourth preferred embodiment of the present invention is similar to the third embodiment in that the injection device is also configured as a two-section device. The difference between this embodiment and the third embodiment lies in the shape of the feed pipe 88 and the shape of the support member 90.

[0076] In this embodiment, the feed pipe 88 extends along the same cross-section in its longitudinal direction, and the cross-section of the feed pipe 88 is set to be circular. That is, the feed pipe 88 is cylindrical.

[0077] Furthermore, the inner liner is also provided with a support member 90 for supporting the feed pipe 88. There is a certain gap between the feed pipe 80 and the inner liner, so that the feed pipe 88 will not directly contact the inner liner. The support member 90 has an arc-shaped support portion 92 that matches the outer circumference shape of the feed pipe 88.

[0078] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0079] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
