Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0055] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0056] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0057] In the related art, when forming the foaming layer, a guide tube is arranged in the foaming cavity, the inlet end of the guide tube is penetrated on the box body, the gun head of the foaming gun is inserted into the guide tube, and the foaming material is injected into the guide tube, and the foaming material flows to different positions of the foaming cavity through the guide tube. However, when the gun head of the foaming gun is inserted into the guide tube and finally withdrawn from the guide tube, it is easy to cause the guide tube to move, thereby affecting the flow of the foaming material and reducing the foaming quality. In order to solve this problem, the present application specifically proposes a refrigerator.

[0058] See also Figure 1 A refrigerator may include a box 10. The box 10 is the outer shell structure of the refrigerator, and is used to accommodate other components, such as an inner tank 20 and a refrigeration system, etc. The box 10 may be in a rectangular shape, or in other shapes.

[0059] In some embodiments, the refrigerator may include an inner container 20. The inner container 20 is disposed in the housing 10, and a refrigeration compartment is formed inside the inner container 20, and the refrigeration compartment is used to store food.

[0060] In some embodiments, the liner 20 may include a refrigeration liner 20. The refrigeration liner 20 is disposed in the box body 10, and the refrigeration chamber may include a refrigeration chamber formed in the refrigeration liner 20. The temperature in the refrigeration chamber may be controlled between 2°C and 8°C, and is mostly used to store fruits and vegetables for daily needs. The front side of the refrigeration chamber may be open to facilitate the entry and exit of refrigerated items.

[0061] In some embodiments, the liner 20 may include a freezing liner 20. The freezing liner 20 is disposed in the housing 10, and the freezing liner 20 may be spaced apart from the refrigerating liner 20, such as the freezing liner 20 may be spaced apart from the refrigerating liner 20 in the vertical direction, or the freezing liner 20 may be spaced apart from the refrigerating liner 20 in the left-right direction. The refrigeration compartment may include a freezing chamber formed by the freezing liner 20, and the temperature in the freezing chamber is relatively low and may be controlled below zero degrees, and may be used to store meat that needs to be stored for a long time. The front side of the freezing chamber may be open to facilitate the entry and exit of frozen objects.

[0062] In some embodiments, the refrigerator may include a door body. The door body may be provided with a refrigerator door and a freezer door corresponding to the refrigerator and the freezer, respectively. The refrigerator door and the freezer door may be rotatably connected to the front side of the box body 10. The refrigerator door is used to open and close the refrigerator, and the freezer door is used to open and close the freezer. When the door body is closed, the refrigerator and the freezer are in a sealed state, which is convenient for storing items at low temperatures and preventing cold from leaking out. When the door body is opened, it is convenient for users to take and put items.

[0063] In some embodiments, the refrigerator may include a refrigeration system for providing coldness for the refrigerator. The refrigeration system may include a compressor, an evaporator, and a condenser. The compressor and the condenser may be arranged in a compressor compartment at the bottom of the box body 10, and the evaporator may be arranged in a refrigeration air duct in the freezing chamber. The compressor, the condenser, and the evaporator may be connected by a capillary tube, and a refrigerant circulates in the capillary tube. The specific working principle of the refrigeration system will not be described in detail here.

[0064] In some embodiments, the outer wall of the liner 20 and the inner wall of the box body 10 are spaced apart, and a foaming cavity 30 is formed between the liner 20 and the box body 10, and the foaming cavity 30 is used to fill the foaming material to keep the liner 20 warm. It can be understood that there is a gap between the liner 20 and the box body 10, mainly between the back side of the liner 20 and the back side of the box body 10, and the foaming material is filled into the foaming cavity 30 from the back side or bottom side of the box body 10.

[0065] In some embodiments, to facilitate the filling of the foaming material, the refrigerator may further include a flow guide 40. The flow guide 40 is disposed in the foaming cavity 30 and is used to introduce the foaming material. When the foaming material is introduced, the tip of a foaming material injection tool such as a foaming gun 60 is inserted into the flow guide 40, and the foaming material is transported into the foaming cavity 30 through the flow guide 40, thereby finally forming a foaming layer.

[0066] See also Figures 2 to 7In some embodiments, a limiting hole 100 communicating with the foaming cavity 30 is provided on the box body 10, and the limiting hole 100 can be provided on the back plate or the bottom plate of the box body 10. The limiting hole 100 runs through the box body 10, and the limiting hole 100 can be a round hole or a square hole, and the shape of the limiting hole 100 can match the shape of the flow guide tube 40. In this embodiment, the limiting hole 100 is a round hole, and the flow guide tube 40 can be a round tube.

[0067] In some embodiments, the inlet end of the flow guide tube 40 is penetrated through the limiting hole 100, and the flow guide tube 40 is connected to the outside of the box body 10 through the limiting hole 100, so as to facilitate the injection of the foaming material. The outlet end of the flow guide tube 40 extends into the foaming cavity 30. When the foaming material is injected, the foaming material is introduced from the inlet end of the flow guide tube 40 and enters the foaming cavity 30 from the outlet end of the flow guide tube 40 to fill the foaming cavity 30 to form a foaming layer.

[0068] In some embodiments, the inlet end of the flow guide tube 40 may be provided with a first limiting portion 400 and a second limiting portion 410 at intervals along the axial direction of the flow guide tube 40. The first limiting portion 400 and the second limiting portion 410 may protrude from the outer peripheral wall of the flow guide tube 40, so that a limiting slot 420 is formed between the first limiting portion 400 and the second limiting portion 410, the outer peripheral wall of the flow guide tube 40 constitutes the bottom wall of the limiting slot 420, and the opposite side of the first limiting portion 400 and the second limiting portion 410 constitutes the side wall of the limiting slot 420.

[0069] In some embodiments, the first limiting portion 400 and the second limiting portion 410 may have the same structure, and may be a ring plate structure protruding from the outer peripheral wall of the flow guide tube 40. The thickness of the two may be the same or different. The first limiting portion 400 and the second limiting portion 410 may be separate components from the flow guide tube 40, and the first limiting portion 400 and the second limiting portion 410 may be detachably connected to the outer peripheral wall of the flow guide tube 40, such as by screw connection or threaded connection.

[0070] In some embodiments, when installing the flow guide tube 40, the hole wall of the limiting hole 100 is inserted into the limiting slot 420 to limit the movement of the flow guide tube 40 along its axial direction, thereby preventing the flow guide tube 40 from being driven by the foaming gun 60 and being displaced when installed on the limiting hole 100. It can be understood that when the first limiting portion 400 and the second limiting portion 410 are detachably connected to the flow guide tube 40, when installing the flow guide tube 40 to the foaming chamber 30, the flow guide tube 40 can be first passed through the limiting hole 100, and then the first limiting portion 400 and the second limiting portion 410 are respectively installed from both ends of the limiting hole 100, so that the hole wall of the limiting hole 100 is inserted into the limiting slot 420, and the outer diameters of the first limiting portion 400 and the second limiting portion 410 are both larger than the inner diameter of the limiting hole 100.

[0071] In some embodiments, an insertion hole 110 communicating with the foaming cavity 30 is provided on the box body 10, and the insertion hole 110 and the limiting hole 100 are adjacent and located on the same wall surface of the box body 10. The inner diameter of the insertion hole 110 is at least larger than one of the outer diameters of the first limiting portion 400 and the second limiting portion 410, such as the inner diameter of the insertion hole 110 is larger than the outer diameter of the first limiting portion 400 or the second limiting portion 410, or both are larger than the outer diameters of the first limiting portion 400 and the second limiting portion 410, so that when the guide tube 40 is installed, at least one of the first limiting portion 400 and the second limiting portion 410 can pass through the insertion hole 110, so that the first limiting portion 400 and the second limiting portion 410 are respectively located on both sides of the insertion hole 110.

[0072] In this embodiment, the inner diameter of the insertion hole 110 is equal to the outer diameter of the first limiting portion 400 and the second limiting portion 410, so that the flow guide tube 40 can be installed from the outside to the inside or from the inside to the outside. The first limiting portion 400 is closer to the outlet end of the flow guide tube 40 than the second limiting portion 410. After the flow guide tube 40 is installed, the first limiting portion 400 is located outside the foaming cavity 30, and the second limiting portion 410 is located inside the foaming cavity 30.

[0073] Continue to see Figure 5 In some embodiments, the hole wall of the insertion hole 110 may be provided with a first notch 111, and the hole wall of the limiting hole 100 may be provided with a second notch 101. The first notch 111 and the second notch 101 are connected, so that the insertion hole 110 and the limiting hole 100 are connected. When the flow guide tube 40 is installed, the inlet end of the flow guide tube 40 can enter the limiting hole 100 through the insertion hole 110, the first notch 111 and the second notch 101 in sequence. It can be understood that the first limiting portion 400 and the second limiting portion 410 can be integrally formed with the flow guide tube 40. At this time, by providing the insertion hole 110, it is convenient to first use the insertion hole 110 to insert the inlet end of the flow guide tube 40, so that one of the first limiting portion 400 and the second limiting portion 410 can pass through the insertion hole 110 and be located outside the limiting hole 100.

[0074] In some embodiments, the first notch 111 and the second notch 101 can be directly connected. A connecting hole 120 can also be provided between the first notch 111 and the second notch 101. The insertion hole 110 is connected to the limiting hole 100 through the connecting hole 120. The inlet end of the guide tube 40 can enter the limiting hole 100 through the insertion hole 110, the first notch 111, the connecting hole 120 and the second notch 101 in sequence. The connecting hole 120 plays a transition role, making it smoother for the guide tube 40 to enter the limiting hole 100 from the insertion hole 110. Among them, the connecting hole 120 can be a rectangular hole, so that the opening size of the first notch 111 and the second notch 101 is the same.

[0075] In some embodiments, a first baffle 130 capable of covering the insertion hole 110 may be movably provided on the inner side of the box body 10. After the guide tube 40 enters the limiting hole 100 from the insertion hole 110, the first baffle 130 may cover the insertion hole 110 to prevent the foaming material from leaking from the box body 10 through the insertion hole 110 to the outside of the box body 10.

[0076] See also Figure 2 In some embodiments, the first baffle 130 has a first working position and a second working position. When the first baffle 130 is in the first working position, the first baffle 130 is misaligned with the insertion hole 110, so that the inlet end of the flow guide tube 40 can pass through the insertion hole 110 to be installed in the limiting hole 100. At this time, the first baffle 130 can be parallel to the axial direction of the insertion hole 110, so that the flow guide tube 40 can extend into the insertion hole 110 without hindrance.

[0077] See also Figure 3 In some embodiments, when the first baffle 130 is located at the second working position, the inlet end of the guide tube 40 is inserted into the limiting hole 100, and the first baffle 130 is attached to the inner wall of the box body 10, thereby covering the insertion hole 110 to prevent the foam material from leaking.

[0078] In some embodiments, a rotating seat 140 may be provided on the inner side wall of the box body 10. The rotating seat 140 may be located on the upper side of the insertion hole 110, and the first baffle 130 is rotatably connected to the rotating seat 140 to switch between the first working position and the second working position. By providing the rotating seat 140, the first baffle 130 can be rotatably connected and can automatically rotate to the second working position under the influence of its own gravity. At this time, the first baffle 130 can be perpendicular to the axial direction of the insertion hole 110, so as to be attached to the inner side wall of the box body 10 and cover the insertion hole 110.

[0079] In some embodiments, the rotating seat 140 may include a seat body and a rotating shaft fixed on the inner wall of the box body 10, and two opposite rotating holes are opened on the seat body. The rotating shaft is rotatably arranged in the two rotating holes, and one end of the first baffle 130 is connected to the rotating shaft, so that the rotation of the rotating shaft can drive the rotation of the first baffle 130.

[0080] In some embodiments, the end of the first baffle 130 away from the rotating seat 140 may have a bayonet 131 that matches the shape of the second limiting portion 410, such as the bayonet 131 may be annular, and the inner diameter of the bayonet 131 may match the outer diameter of the second limiting portion 410. When the first baffle 130 is located at the second working position, the second limiting portion 410 is engaged in the bayonet 131, so that the first baffle 130 is used to cover all the positions of the insertion hole 110 and the limiting hole 100 where there is a gap with the guide tube 40, so as to prevent the foaming material from leaking from the insertion hole 110 or the limiting hole 100 when injected.

[0081] In some embodiments, the refrigerator may further provide at least two branch pipes 50. The inlet ends of the at least two branch pipes 50 are both connected to the outlet end of the flow guide pipe 40, and the at least two branch pipes 50 extend in different directions to transport the foaming material in the flow guide pipe 40 to different positions of the foaming cavity 30. When the foaming material is injected, the foaming material is introduced into each branch pipe 50 from the inlet end of the flow guide pipe 40, and enters the foaming cavity 30 from the outlet end of each branch pipe 50, so that the foaming material is more evenly distributed in the foaming cavity 30, which can improve the thermal insulation of the foaming layer.

[0082] In some embodiments, the branch pipes 50 may include two, three or four, etc., so as to form multiple outlets. In this embodiment, two branch pipes 50 are provided, and the two branch pipes 50 extend in opposite directions to form a Y-shaped structure with the guide pipe 40.

[0083] In some embodiments, the branch pipe 50 may be arranged to be tilted downward relative to the guide pipe 40, so as to prevent the foaming material from flowing back into the guide pipe 40 from the outlet end of the branch pipe 50 by the influence of weight after the foaming material is injected. The downward tilt angle of the branch pipe 50 may be between 10° and 20°, and the branch pipe 50 may be tilted downward by 10°, 15°, or 20°, etc.

[0084] See also Figures 2 to 4 It can be understood that when injecting the foaming material, for the convenience of operation, the box body 10 is placed flat on the operating table. At this time, the guide tube 40 can extend in the horizontal direction, and a limiting hole 100 is opened on the bottom plate of the box body 10, so as to inject the foaming material into the foaming cavity 30 located on the back side of the refrigerator. When installing the guide tube 40, the guide tube 40 and the branch pipe 50 can be first arranged in the foaming cavity 30, and then the inlet end of the guide tube 40 is inserted from the inside to the outside into the insertion hole 110, and then enters the limiting hole 100 through the connecting hole 120, and the limiting card slot 420 is used to clamp the hole wall of the limiting hole 100 to complete the fixing of the guide tube 40, and finally the foaming gun 60 is used to inject the foaming material into the guide tube 40, and the foaming material finally flows to different positions in the foaming cavity 30 through the branch pipe 50.

[0085] In some embodiments, a second baffle 500 may be provided on the branch pipe 50. The second baffle 500 can close the outlet end of the branch pipe 50, so that after the foaming material is injected, the branch pipe 50 is closed by the second baffle 500 to further prevent the foaming material from flowing back to the guide pipe 40. The second branch pipe 50 can be arranged inside the branch pipe 50 or outside the branch pipe 50, as long as the branch pipe 50 can be selectively closed.

[0086] In this embodiment, the second baffle 500 is located outside the branch pipe 50, and the second baffle 500 can be rotatably connected to the outlet end of the branch pipe 50, so that the second baffle 500 can be rotated in a direction away from the outlet end of the branch pipe 50, so that the second baffle 500 and the outlet end of the branch pipe 50 are staggered in the axial direction of the branch pipe 50, so as to open the outlet end of the branch pipe 50, so as to facilitate the injection of the foaming material from the branch pipe 50 into the foaming cavity 30. The second baffle 500 can be rotated to cover the outlet end of the branch pipe 50 to close the outlet end of the branch pipe 50. At this time, the second baffle is perpendicular to the axial direction of the branch pipe 50 and fits at the outlet end of the branch pipe 50. Among them, one end of the second baffle 500 can be rotatably connected to the pipe edge of the outlet end of the branch pipe 50, and the second baffle 500 can match the shape and size of the outlet end of the branch pipe 50.

[0087] In summary, in this embodiment, by providing the first limiting portion 400 and the second limiting portion 410 at the inlet end of the flow guide tube 40, when installing the flow guide tube 40, the hole wall of the limiting hole 100 on the box body 10 can be clamped in the limiting clamping groove 420 formed between the first limiting portion 400 and the second limiting portion 410, thereby limiting the axial movement of the flow guide tube 40, avoiding displacement by the foaming material injection tool such as the foaming gun 60, thereby avoiding affecting the flow of the foaming material and improving the foaming quality. At the same time, by providing the insertion hole 110, it is convenient for the flow guide tube 40 to enter the limiting hole 100 through the insertion hole 110, and it is convenient for the flow guide tube 40 to be clamped and fixed with the limiting hole 100.
