[0036] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] Reference Figure 1 and Figure 2 In one embodiment of the present invention, a refrigerator 100 is provided, which may include a body 1 provided with a storage chamber 2 and a door body 3 for opening and closing the storage chamber 2, the door body 3 may include an outer shell 4 and an inner shell 5 arranged relatively spaced apart, a heat preservation space 8 may be formed between the outer shell 4 and the inner shell 5, and the heat preservation space 8 may be filled with heat preservation material.

[0038] The door body 3 may be provided with an ice-making chamber 6, which may be provided in the housing 4 and the opening of the ice-making chamber 6 may face outward. The refrigerator 100 may further include an ice-making chamber door 13, which may be used to open and close the opening of the ice-making chamber 6.

[0039] The side wall of the ice making chamber 6 may be provided with an ice making water injection member 7. The ice making water injection member 7 is fastened to the side wall of the ice making chamber 6 through a fixing structure. The ice making water injection member 7 is at least partially disposed in the heat preservation space 8. The ice making water injection member 7 is connected to an ice making water pipe 9 extending at least partially in the heat preservation space 8.

[0040] In this embodiment, up and down may refer to the height direction of the refrigerator 100. For the cabinet 1, front and back may refer to the depth direction of the cabinet 1, and the storage chamber 2 opening direction may be the front. For the door 3, front and back may refer to the thickness direction of the door 3, and the side of the door 3 close to the opening of the refrigerator chamber may be the rear. Left and right may refer to the width direction of the cabinet 1 or the door 3.

[0041] The storage chamber 2 may be a refrigerating chamber disposed on the upper portion of the box body 1. The storage chamber 2 may be opened and closed by a single door or by a double door. The inner shell 5 may be disposed on the side of the door body 3 facing the opening of the refrigerating chamber. The outer shell 4 may be disposed on the side of the door body 3 away from the opening of the refrigerating chamber.

[0042] The outer shell 4 and the inner shell 5 may be filled with heat-insulating material in a foaming manner. Since the temperature in the storage chamber 2 is often lower than the ambient temperature of the refrigerator 100, filling the heat-insulating material between the outer shell 4 and the inner shell 5 can isolate the heat transfer between the storage chamber 2 and the environment outside the door body 3, thereby achieving the heat-insulating performance of the door body 3 and preventing the loss of cold in the storage chamber 2.

[0043] The ice making chamber 6 may be provided with an ice maker for making ice cubes and an ice storage box for storing ice cubes arranged below the ice maker, and the left and right side walls of the ice making chamber 6 may be provided with an air inlet 61 and an air return port 62. The refrigerator 100 may be provided with an evaporator chamber, and the air inlet 61 and the air return port 62 may be connected to the evaporator chamber through an air duct.

[0044] The cold air in the evaporator room can be blown to the ice maker through the air inlet duct and the air inlet 61 to make ice cubes, and the air in the ice making room 6 can flow back to the evaporator room through the return air port 62 and the return air duct, thereby forming an air circulation.

[0045] The opening of the ice-making chamber 6 may face outward, i.e., the front side of the door body 3. The ice-making chamber door 13 may be pivotally arranged at the front side of the opening of the ice-making chamber 6. The interior of the ice-making chamber door 13 may be filled with a heat-insulating material, thereby isolating the heat transfer between the ice-making chamber 6 and the environment outside the ice-making chamber door 13, and preventing the loss of cold in the refrigeration chamber.

[0046] With such arrangement, the user can take ice cubes from the ice making chamber 6 by opening the ice making chamber door 13 on the front side of the door body 3 without opening the storage chamber 2, thereby reducing the loss of cold in the storage chamber 2 and making it easier for the user to take ice.

[0047] The ice-making water injection member 7 can be used to connect the ice-making water pipe 9. One end of the ice-making water pipe 9 is connected to the ice-making water injection member 7, and the other end can be connected to a water source. The ice-making water injection member 7 and the ice-making water pipe 9 can transport water from the water source to the ice-making machine in the ice-making chamber 6, so that the ice-making machine can make ice cubes.

[0048] The water source of the ice-making chamber 6 on the door body 3 can be an external water source or an internal water source.

[0049] The external water source may refer to a water source disposed outside the refrigerator 100, such as tap water at a user's home. A water channel module may be disposed in the storage chamber 2, and the water channel module may be connected to tap water through a water pipe. The ice-making water pipe 9 may extend outside the door body 3 and be connected to the water channel module, thereby realizing the setting of an ice-making water channel between the external water source and the ice-making chamber 6.

[0050] The internal water source may refer to a water storage box disposed in the refrigerator 100, and the water storage box may be disposed in the storage chamber 2 of the refrigerator 100. The ice-making water pipe 9 may extend outside the door body 3 and be connected to the water storage box, thereby realizing the setting of the ice-making water supply waterway between the internal water source and the ice-making chamber 6.

[0051] In this embodiment, the ice-making water injection member 7 is fastened to the side wall of the ice-making chamber 6 by a fixing structure. In the existing ice-making water injection member 7 and the side wall of the ice-making chamber 6, there is often no special fixing structure provided between the ice-making water injection member 7 and the side wall of the ice-making chamber 6, and the ice-making water injection member 7 is generally fixed to the side wall of the ice-making chamber 6 by a foamed and filled insulation material. Alternatively, a limiting guide structure is provided between the ice-making water injection member 7 and the side wall of the ice-making chamber 6, and the ice-making water injection member 7 can slide relative to the ice-making chamber 6 through the limiting guide structure, so as to guide the connection and cooperation between the ice-making water injection member 7 and the side wall of the ice-making chamber 6 when the inner shell 5 and the outer shell 4 are molded, and then the ice-making water injection member 7 is fixed to the side wall of the ice-making chamber by the foamed and filled insulation material.

[0052] The meaning of the fixed structure in the present invention is different from the limiting guide structure in the prior art. The fixed structure in the present invention is required to have the feature that the ice-making water injection component 7 does not need to be fixed by a foamed and filled insulation material, so that the ice-making water injection component 7 can be firmly arranged on the side wall of the ice-making chamber 6, so that the ice-making water injection component 7 will not move up and down, forward and backward, and left and right relative to the side wall of the ice-making chamber 6.

[0053] Preferably, the fixing structure of the present invention may also include preventing the ice-making water injection member 7 from moving up and down, forward and backward, left and right relative to the side wall of the ice-making chamber 6, and also preventing it from rotating relative to the side wall of the ice-making chamber 6.

[0054] Accordingly, in this embodiment, the meaning of fastening may refer to that the ice-making water injection member 7 is tightly fixed to the side wall of the ice-making chamber 6, so that the ice-making water injection member 7 does not move up and down, forward and backward, or left and right relative to the side wall of the ice-making chamber 6. Preferably, the meaning of fastening may also include that the ice-making water injection member 7 does not rotate relative to the side wall of the ice-making chamber 6.

[0055] In the actual manufacturing process of the door body 3 , it is often necessary to place the outer shell 4 in an outer shell mold, and the inner shell 5 in an inner shell mold, and then fill the outer shell mold and the inner shell mold with foam material.

[0056] In this embodiment, the ice-making chamber 6 is arranged on the outer shell 4, and the ice-making water injection piece 7 is arranged on the ice-making chamber 6, that is, the ice-making chamber 6 and the ice-making water injection piece 7 are both arranged on the outer shell 4, the ice-making water injection piece 7 will not fall off from the side wall of the ice-making chamber 6, and the ice-making chamber 6 and the ice-making water injection piece 7 are not connected to the inner shell 5.

[0057] With such an arrangement, it is possible to fasten the ice-making water injection component 7 to the ice-making chamber 6 through the fixed structure before the outer shell mold and the inner shell mold are closed and the foaming material is filled, so that the outer shell 4, the ice-making water injection component 7 and the ice-making chamber 6 can form a tightly connected component, ensuring that the ice-making water injection component 7 will not move relative to the ice-making chamber 6 or fall off the ice-making chamber 6, and can achieve a tight connection and precise fit between the ice-making water injection component 7 and the ice-making chamber 6, preventing a gap between the ice-making water injection component 7 and the ice-making chamber 6 due to poor assembly fit, and can effectively prevent the thermal insulation material from overflowing from the thermal insulation space 8 into the ice-making chamber 6 when the thermal insulation material is foamed and filled.

[0058] In addition, since the ice-making chamber 6 and the ice-making water injection part 7 can be assembled in advance before filling the foaming material, instead of being assembled during the mold closing process, compared with the prior art, the present invention can facilitate the mold closing of the outer shell mold and the inner shell mold, which is beneficial to on-site production, can effectively reduce the time cost and labor cost of production, and improve the production efficiency and quality of the product.

[0059] Reference Figure 3 and Figure 4 Furthermore, in this embodiment, a method for manufacturing the door body 3 of the refrigerator 100 is also provided, which may include:

[0060] An ice-making chamber 6 is provided on the outer shell 4 of the door body 3, and an ice-making water injection member 7 is fixed to the side wall of the ice-making chamber 6 to form an outer shell pre-assembly assembly 110;

[0061] Placing the housing pre-assembly component 110 in a housing mold;

[0062] Placing the inner shell 5 of the door body 3 in the inner shell mold;

[0063] The outer shell mold and the inner shell mold are molded together and the foaming material is injected.

[0064] Such an arrangement can achieve a close connection and precise fit between the ice-making water injection component 7 and the ice-making chamber 6, prevent a gap between the ice-making water injection component 7 and the ice-making chamber 6 due to poor assembly fit, and effectively prevent the insulation material from overflowing from the insulation space 8 into the ice-making chamber 6 when the insulation material is foamed and filled, and can facilitate the closing of the outer shell mold and the inner shell mold, which is beneficial to on-site production and improves product production efficiency and quality.

[0065] Reference Figure 2 , Figure 3 , Figure 5 , Figure 6Further, in this embodiment, the side wall of the ice making chamber 6 may be provided with an installation opening 63. The inner wall of the installation opening 63 may be provided with a plurality of spaced snap-in protrusions 64. The ice making water injection member 7 may include a fixing plate 71, and the fixing plate 71 may abut against the side of the heat preservation space 8 of the side wall of the ice making chamber 6 and cover the installation opening 63.

[0066] The ice-making water injection member 7 may further include a circular fixing wall 72 extending from the fixing plate 71 into the mounting opening 63 . The circular fixing wall 72 may cooperate with the inner wall of the mounting opening 63 . The circular fixing wall 72 is provided with a snap-fit ​​opening 73 that cooperates with the snap-fit ​​protrusion 64 .

[0067] The fixing structure in this embodiment refers to the structure that cooperates with each other among the fixing plate 71, the circular fixing wall 72, the clamping opening 73, the mounting opening 63, and the clamping protrusion 64. The fixing plate 71 abuts against the insulation space 8 side of the side wall of the ice-making chamber 6 and covers the mounting opening 63, so as to limit the displacement of the ice-making water injection member 7 toward the ice-making chamber 6, and at the same time, it can also play a role in preventing the insulation material from entering the ice-making chamber 6.

[0068] The mounting opening 63 can be set to a rectangular shape, and the annular fixed wall 72 can be a rectangular annular wall arranged in cooperation with the mounting opening 63. Such a setting can limit the lateral movement and rotation of the ice-making water injection component 7 relative to the side wall of the ice-making chamber 6, and at the same time, can further play a role in blocking the heat-insulating material from entering the ice-making chamber 6.

[0069] There can be four snap-fitting protrusions 64, which are respectively arranged on each side wall of the rectangular installation opening 63. Correspondingly, there are also four snap-fitting openings 73. When the ring-shaped fixed wall 72 enters the installation opening 63, the snap-fitting protrusions 64 can also enter the corresponding snap-fitting openings 73 and snap-fit ​​with the snap-fitting openings 73. Such an arrangement can limit the displacement of the ice-making water injection member 7 toward the outside of the ice-making chamber 6, and can also further limit the lateral movement and rotation of the ice-making water injection member 7.

[0070] During installation, the ice-making water injection component 7 can be moved from the insulation space 8 side of the side wall of the ice-making chamber 6 toward the ice-making chamber 6, so that the annular fixed wall 72 enters the installation opening 63, and then the fixed plate 71 is abutted against the insulation space 8 side of the side wall of the ice-making chamber 6, so that the snap-fitting protrusion 64 and the snap-fitting opening 73 are snapped into each other, thereby fastening the ice-making water injection component 7 to the side wall of the ice-making chamber 6.

[0071] Through the structural design of the fixing plate 71, the circular fixing wall 72, and the snap-on opening 73 on the ice-making water injection member 7, as well as the structural design of the mounting opening 63 and the snap-on protrusion 64 on the side wall of the ice-making chamber 6, the ice-making water injection member 7 can be fastened to the side wall of the ice-making chamber 6 to prevent the ice-making water injection member 7 from moving up and down, left and right, front and back, and rotating relative to the side wall of the ice-making chamber 6, thereby ensuring the tight connection and fit between the ice-making water injection member 7 and the side wall of the ice-making chamber 6, and effectively preventing the thermal insulation material from overflowing from the thermal insulation space 8 into the ice-making chamber 6. The structure is simple, the installation is convenient, and the fastening effect is good.

[0072] Furthermore, in the present embodiment, a limiter for restricting the routing of the ice-making water pipe 9 is disposed in the heat-insulating space 8 , and the limiter is disposed on the outer shell 4 and / or the side wall of the ice-making chamber 6 .

[0073] Since the ice-making water pipe 9 needs to extend from the ice-making water injection part 7 to the outside of the door body 3 in the heat-insulating space 8, a limiter needs to be provided to ensure that the ice-making water pipe 9 can be routed in a preset manner and to prevent the ice-making water pipe 9 from freezing, condensation on the door body 3, interference between the ice-making water pipe 9 and other structures, etc. due to unreasonable routing.

[0074] The limiting member may have one or more. The limiting member may be provided in a hook or buckle-shaped structure, or may be other structures, as long as it can fix the ice-making water pipe 9 and ensure that the ice-making water pipe 9 will not move around or fall off.

[0075] In this embodiment, the ice-making water pipe 9 can be connected to the ice-making water injection piece 7 at one end and can extend freely at the other end. The part between the two ends can be fixed by a limiter so that the ice-making water pipe 9 can extend on the outer shell 4 in a preset manner, that is, the ice-making chamber 6, the ice-making water injection piece 7, and the ice-making water pipe 9 are all arranged on the outer shell 4, and the ice-making water pipe 9 is not connected to the inner shell 5.

[0076] Such an arrangement makes it possible to arrange the ice-making water pipe 9 on the outer shell 4 before the outer shell mold and the inner shell mold are closed and filled with the foaming material, so that the ice-making water pipe 9 and the outer shell 4, the ice-making chamber 6, and the ice-making water injection part 7 form a component that can be moved and assembled as a whole, which is convenient for the installation of the ice-making water pipe 9 and the close connection between the ice-making water pipe 9 and the ice-making water injection part 7, and can ensure the accurate routing of the ice-making water pipe 9.

[0077] In addition, since the ice-making water pipe 9, the ice-making water injection part 7, and the ice-making chamber 6 are all arranged on the ice-making outer shell 4, and there is no connecting structure between them and the inner shell 5, there is no need to consider the mutual coordination of the ice-making chamber 6, the ice-making water pipe 9, the ice-making water injection part 7 and the inner shell 5 when the outer shell mold and the inner shell mold are molded together. This can facilitate the mold assembly of the outer shell mold and the inner shell mold, is beneficial to on-site production, can effectively reduce the time cost and labor cost of production, and improve the production efficiency and quality of the product.

[0078] Furthermore, in this embodiment, the ice-making water injection member 7 and the ice-making water pipe 9 are connected by injection molding or welding.

[0079] The injection molding connection can be achieved by plugging one end of the ice-making water pipe 9 and the ice-making water injection piece 7 into each other, and then placing the connecting part of the ice-making water pipe 9 and the ice-making water injection piece 7 into an injection mold, and by injection molding the injection molding material on the outside of the connecting part of the ice-making water pipe 9 and the ice-making water injection piece 7, a sealed connection between the ice-making water pipe 9 and the ice-making water injection piece 7 is achieved.

[0080] The welding can be done by using plastic material for both the ice-making water pipe 9 and the ice-making water injection piece 7, plugging one end of the ice-making water pipe 9 into the ice-making water injection piece 7, and then placing the connecting part of the ice-making water pipe 9 and the ice-making water injection piece 7 into a mold, and heating the connecting part of the ice-making water pipe 9 and the ice-making water injection piece 7 to melt them and cool them to form an inseparable integrated structure.

[0081] Reference Figure 3 Further, in this embodiment, the manufacturing method of the door body 3 of the refrigerator 100, wherein the shell pre-assembled component 110 may also include an ice-making water pipe 9 for conveying water to the ice-making chamber 6, and the manufacturing method may also include:

[0082] The ice-making water injection component 7 and the ice-making water pipe 9 are connected by injection molding or welding to form a pre-assembled assembly of the ice-making water injection component 7;

[0083] The pre-assembled assembly of the ice-making water injection member 7 is fixed to the side wall of the ice-making chamber 6 to form the shell pre-assembled assembly 110 .

[0084] Pre-installing the ice-making water injection component 7 and the ice-making water pipe 9 in advance to form a pre-installed assembly of the ice-making water injection component 7 can facilitate adaptation to the mass production environment of the factory and improve the manufacturing efficiency of the door body 3. The ice-making water injection component 7 and the ice-making water pipe 9 are connected by injection molding or hot melting, which can ensure the sealing of the connection between the ice-making water pipe 9 and the ice-making water injection component 7, and the connection has high reliability and long service life, and can effectively avoid water leakage at the connection between the ice-making water pipe 9 and the ice-making water injection component 7.

[0085] In this embodiment, the ice-making water injection member 7 can be fastened to the top wall of the ice-making chamber 6. An ice-making tray is arranged in the ice-making chamber 6, and the ice-making tray can be opened toward the top wall of the ice-making chamber 6. A first water flow channel 75 extending longitudinally can be formed inside the ice-making water injection member 7, and the lower end of the first water flow channel 75 can be placed in the ice-making chamber 6 and above the ice-making tray.

[0086] The ice tray is one of the components of the ice maker. The ice tray can be provided with a plurality of ice grids with openings upward, and the ice-making water injection member 7 injects water into the ice tray through the first water flow channel 75. After the water flows into the ice grid, heat exchange is performed between the water and the cold air entering from the air inlet 61 to form ice cubes.

[0087] The existing ice-making water injection component 7 is generally arranged on the rear wall of the ice-making chamber 6. In the present invention, the ice-making water injection component 7 is arranged on the top wall of the ice-making chamber 6, which can avoid the ice-making water injection component 7 occupying the space in the thickness direction of the door body 3, and further compress the thickness of the door body 3 to design an ultra-thin door body 3. In addition, the ice tray can be arranged as close to the top wall of the ice-making chamber 6 as possible, so that the ice maker is arranged more compactly in the height direction, saving the space of the ice-making chamber 6 and improving the utilization rate of the space of the ice-making chamber 6.

[0088] Reference Figure 2 , Figure 3 and Figure 6 Furthermore, in the present embodiment, the upper end of the first water flow channel 75 is placed in the heat preservation space 8, and the cross-sectional size of the first water flow channel 75 gradually increases from top to bottom.

[0089] Furthermore, in this embodiment, the water flow channel may include a second water flow channel 76 extending laterally, one end of the second water flow channel 76 is connected to the upper end of the first water flow channel 75, and the other end is connected to the ice-making water pipe 9, and the end of the ice-making water pipe 9 is sleeved in the second water flow channel 76, and the cross-sectional size of the second water flow channel 76 is smaller than the cross-sectional size of the first water flow channel 75.

[0090] Furthermore, in this embodiment, the cross-sectional size of the ice-making water pipe 9 is smaller than the cross-sectional size of the second water flow channel 76 .

[0091] The first water flow channel 75 adopts a variable size design in which the cross-sectional size of the water flow channel gradually increases from top to bottom, or a design in which the water flow cross-sectional space size from the ice-making water pipe 9 to the second water flow channel 76 is increased, or a design in which the water flow cross-sectional space size from the second water flow channel 76 to the first water flow channel 75 is increased. This can increase the space for water flow, increase the energy loss of water during the flow process, and reduce the water flow rate, thereby reducing the impact of water flowing from the lower end of the first water flow channel 75 to the ice tray on the ice tray, so that water can enter the ice tray more smoothly from the ice-making water injection piece 7, thereby avoiding water splashing in the ice-making chamber 6.

[0092] Reference Figure 2 , Figure 3 and Figure 6Furthermore, in the present embodiment, the second water flow channel 76 extends laterally from the upper end of the first water flow channel 75 toward the opening direction of the ice-making chamber 6, the door body 3 is pivotally arranged on the box body 1, and at least part of the ice-making water pipe 9 extends along the top wall of the ice-making chamber 6 and the side wall of the ice-making chamber 6 close to the pivot axis side of the door body 3.

[0093] The ice-making water pipe 9 can continue to extend laterally toward the opening of the ice-making chamber 6 from the connection point with the second water flow channel 76, then turn left or right about 90 degrees to continue to extend laterally to the left side wall or right side wall of the ice-making chamber 6, then turn downward about 90 degrees to extend longitudinally downward along the left side wall or right side wall of the ice-making chamber 6, and then extend upward along the pivot axis of the door body 3, and extend out of the door body 3 from the upper end of the door body 3.

[0094] In this embodiment, the longitudinal extension may refer to a vertical extension, or an extension at a certain angle relative to the vertical extension, and the overall trend is that the vertical extension is extended. The lateral extension may refer to a completely horizontal extension, or an extension slightly inclined at a certain angle relative to the horizontal plane, and the overall trend is that the lateral extension is extended.

[0095] Such an arrangement can increase the number of turns of water in the ice-making water pipe 9, increase the overall length of the water flow path, thereby increasing the energy loss of water during the flow process, and reduce the water flow rate, thereby reducing the impact of water flowing from the lower end of the first water flow channel 75 to the ice-making tray on the ice-making tray, so that water can enter the ice-making tray more smoothly from the ice-making water injection piece 7, avoiding water splashing in the ice-making chamber 6.

[0096] Reference Figure 2 , Figure 3 and Figure 6 Furthermore, in the present embodiment, the ice-making water injection component 7 may also include a limiting wall 74 extending along the rear wall of the ice-making chamber 6, and the upper edge of the limiting wall may be connected to the rear edge of the fixed wall 71. The limiting wall 74 is used to lean against the rear wall of the ice-making chamber 6 so that the ice-making water injection component 7 can be more firmly fixed on the top wall of the ice-making chamber, thereby limiting the forward movement or rotation of the ice-making water injection component.

[0097] Reference Figure 1 , Figure 2 , Figure 4 Further, in this embodiment, the door body 3 may include a decorative strip 10 connecting the periphery of the outer shell 4 and the periphery of the inner shell 5. A hinge 15 is provided between the box body 1 and the upper end of the door body 3. One end of the hinge 15 is fixedly connected to the box body 1, and the other end is provided with a hinge shaft 151 rotatably connected to the decorative strip 10.

[0098] The heat preservation space 8 is provided with a pipe sleeve 11 extending longitudinally along the decorative strip 10 on the side of the pivot axis of the door body 3. The upper end of the pipe sleeve 11 can be connected to the decorative strip 10. The pipe sleeve 11, the hinge shaft 151 and the decorative strip 10 form a wiring channel extending longitudinally and passing through the inside and outside of the heat preservation space 8.

[0099] The ice-making water pipe 9 extends through the wiring channel to the outside of the door body 3. The decorative strip 10 on the side of the pivot axis of the door body 3 is provided with a longitudinally extending limit strip 1031, and the limit strip 1031 is connected to the pipe sleeve 11.

[0100] The decorative strip 10 may include an upper decorative strip 101 connecting the upper edge of the outer shell 4 and the inner shell 5, a lower decorative strip 102 connecting the lower edge of the outer shell 4 and the inner shell 5, a left decorative strip 103 connecting the left edge of the outer shell 4 and the inner shell 5, and a right decorative strip 104 connecting the right edge of the outer shell 4 and the inner shell 5. The decorative strips 10 are used to connect the outer shell 4 and the inner shell 5 on each side of the door body 3 in the thickness direction, which can be more convenient for processing, manufacturing, transportation and assembly.

[0101] Reference Figure 4 Further, in the present embodiment, the manufacturing method of the door body 3 of the refrigerator 100, wherein the door body 3 may further include a decorative strip 10 for connecting the outer shell 4 and the inner shell 5, "placing the inner shell 5 of the door body 3 in an inner shell mold; closing the outer shell mold and the inner shell mold and injecting the foaming material" may specifically include:

[0102] Connecting the trim strip 10 of the door body 3 and the periphery of the inner shell 5 to form an inner shell pre-assembled component 120;

[0103] Placing the inner shell pre-assembled component 120 in the inner shell mold;

[0104] After the outer shell mold and the inner shell mold are molded together so that the periphery of the outer shell 4 and the decorative strip 10 are connected, the foaming material is injected.

[0105] The upper decorative strip 101 , the lower decorative strip 102 , the left decorative strip 103 , and the right decorative strip 104 may be connected to form a decorative strip 10 frame, and then the decorative strip 10 frame and the inner shell 5 may be connected, so that the assembly of the decorative strip 10 and the inner shell 5 is faster and easier to operate.

[0106] The decorative strip 10 and the inner shell 5 are first connected to form a tightly connected inner shell pre-assembled component 120, which is convenient for adapting to the mass production environment of the factory, and the inner shell pre-assembled component 120 is connected by the decorative strip 10 and the outer shell 4. When closing the mold, it is only necessary to ensure that the outer shell 4 can be accurately docked with the decorative strip 10, which can facilitate the closing of the outer shell mold and the inner shell mold, is conducive to on-site production, can effectively reduce the time cost and labor cost of production, and improve the production efficiency and quality of the product.

[0107] Reference Figures 1 to 4 The pipe sleeve 11 can be made of a material with a certain thickness and heat preservation performance. Since the water temperature in the ice-making water pipe 9 is often lower than the external environment temperature of the refrigerator 100, the ice-making water pipe 9 is sleeved in the pipe sleeve 11 to prevent the ice-making water pipe 9 from directly contacting the front wall or the left and right side walls of the door body 3, thereby preventing condensation from appearing on the surface of the door body 3 due to the temperature difference. In addition, the pipe sleeve 11 can also limit the routing direction of the ice-making water pipe 9 and fix the ice-making water pipe 9.

[0108] The upper end of the pipe sleeve 11 can be detachably plugged into the upper decorative strip 101, and the longitudinally extending side of the pipe sleeve 11 can contact the limiting strip 1031, so that the pipe sleeve 11 can be more firmly fixed in the insulation space 8, avoiding the movement of the pipe sleeve 11, thereby better limiting the ice-making water pipe 9.

[0109] Further, in the present embodiment, the manufacturing method of the door body 3 of the refrigerator 100, wherein the shell pre-assembled component 110 may further include a pipe sleeve 11 sleeved on the outside of the ice-making water pipe 9, and the manufacturing method may further include:

[0110] After the ice-making water injection component 7 pre-assembled assembly is fixed to the side wall of the ice-making chamber 6 , the ice-making water pipe 9 in the ice-making water injection component 7 pre-assembled assembly away from the water injection component is passed through the pipe sleeve 11 to form the shell pre-assembled assembly 110 .

[0111] Before “closing the outer shell mold and the inner shell mold to connect the periphery of the outer shell 4 and the decorative strip 10”, the following may also be included:

[0112] The end of the pipe sleeve 11 of the outer shell pre-assembly component 110 in the outer shell mold is connected to the inner side of the decorative strip 10 of the inner shell pre-assembly component 120 in the inner shell mold. The decorative strip 10 has a through hole 1011, so that the ice-making water pipe 9 passes through the through hole 1011 and out of the decorative strip 10.

[0113] Before the outer shell mold and the inner shell mold are molded together, it is only necessary to insert the sleeve in the outer shell pre-installed component 110 into the upper decorative strip 101 in the inner shell pre-installed component 120, and make the ice-making water pipe 9 pass through the door body 3 from the routing channel formed by the upper decorative strip 101 and the hinge shaft 151, and then the outer shell mold and the inner shell mold can be molded together and foamed and filled with insulation material, which can facilitate the molding of the outer shell mold and the inner shell mold, ensure the accurate matching of the outer shell pre-installed component 110 and the inner shell 5 with the pre-installed parts, is conducive to on-site production, can effectively reduce the time cost and labor cost of production, and improve the production efficiency and quality of products.

The dispenser chamber 12 opens outward and may be placed under the ice-making chamber 6. The housing 4 may be recessed toward the heat-insulating space 8 to form the ice-making chamber 6 and the dispenser chamber 12.

[0115] The shell 4, the ice-making chamber 6, and the dispenser chamber 12 can be integrally manufactured by vacuum forming or injection molding. The ice-making chamber 6, the dispenser chamber 12, and the shell 4 are integrally arranged to avoid the gap caused by the split connection, which causes the insulation material to easily overflow outside the insulation space 8. At the same time, it is convenient for mass production, simplifies the assembly process, and can effectively reduce the time cost and labor cost of manufacturing the door body 3, thereby improving the production efficiency and quality of the door body 3.

[0116] Furthermore, in this embodiment, a water intake and injection component is provided on the side wall of the distributor chamber 12, and the water intake and injection component is fastened to the side wall of the distributor chamber 12 by a fixed structure. The water intake and injection component is at least partially placed in the heat-insulating space 8, and the water intake and injection component is connected to a water intake pipe that extends at least partially in the heat-insulating space 8.

[0117] The shell pre-assembly component 110 may also include a water intake and injection piece and a water intake pipe. The structure of the water intake and injection piece and the fixing structure between the water intake and injection piece and the side wall of the dispenser chamber 12 may be similar to the fixing structure between the ice-making injection piece 7 and the side wall of the ice-making chamber 6. The shell 4 and / or the side wall of the ice-making chamber 6 may be provided with a limiting structure such as a buckle for limiting the routing of the water intake pipe. The water intake pipe may extend out of the door body 3 from the routing channel formed by the pipe sleeve 11, the hinge shaft 151 and the decorative strip 10 and extending longitudinally and passing through the inside and outside of the insulation space 8, and be connected to an external water source or an internal water source.

[0118] Such an arrangement can facilitate the mass production of the door body 3, simplify the assembly process of the door body 3, ensure the mutual cooperation between the ice-making and water-injecting parts 7 of the door body 3 and the side walls of the ice-making chamber 6, and the tight connection and mutual cooperation between the water-taking and water-injecting parts and the side walls of the dispenser chamber 12, thereby preventing the insulation material in the insulation space 8 from overflowing into the ice-making chamber 6 or the dispenser chamber 12, and can facilitate the pre-assembly to form the outer shell pre-assembly component 110 and the inner shell pre-assembly component 120, facilitate the mold closing of the outer shell mold and the inner shell mold, simplify the connection and matching structure between the outer shell pre-assembly component 110 and the inner shell pre-assembly component 120, and can effectively reduce the time cost and labor cost of manufacturing the door body 3, and improve the production efficiency and quality of the door body 3.

[0119] Reference Figure 1 The door body 3 may further include an outer door 14 pivotably disposed on the outer side of the housing 4. The outer door 14 may be used to simultaneously open and close the ice making chamber 6 and the dispenser chamber 12. The outer door 14 may be disposed on the outer side of the ice making chamber door 13.

[0120] To sum up, the manufacturing method of the refrigerator 100 and the refrigerator door 3 of the present invention can solve the problem in the prior art that the ice-making water injection part 7 and the opening of the ice-making chamber 6 are easily misaligned when the outer shell 4 and the inner shell 5 are molded together, and there is a gap between the ice-making water injection part 7 and the water injection port, thereby causing the thermal insulation material to overflow.

[0121] By adopting the technical solution of the present application, the housing 4, the ice-making water injection member 7, the ice-making chamber 6, the distributor chamber 12, and the water-intake water injection member can form a tightly connected assembly, ensuring that the ice-making water injection member 7 will not move relative to the ice-making chamber 6 or fall off from the ice-making chamber 6, ensuring that the water-intake water injection member will not move relative to the distributor chamber 12 or fall off from the distributor chamber 12, and can achieve tight connection and precise fit between the ice-making water injection member 7 and the ice-making chamber 6, and between the water-intake water injection member and the distributor chamber 12, preventing gaps from being generated due to poor assembly fit, and can It can effectively prevent the thermal insulation material from overflowing from the thermal insulation space 8 into the ice-making chamber 6 or the dispenser chamber 12 when the thermal insulation material is foamed and filled, can facilitate the mass production of the door body 3, simplify the assembly process of the door body 3, can facilitate the pre-assembly to form the outer shell pre-assembly component 110 and the inner shell pre-assembly component 120, facilitate the mold closing of the outer shell mold and the inner shell mold, simplify the connection and matching structure between the outer shell pre-assembly component 110 and the inner shell pre-assembly component 120, can effectively reduce the time cost and labor cost of manufacturing the door body 3, and improve the production efficiency and quality of the door body 3.
