DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0032] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0033] The inventors found that when producing high-energy refrigerators, the provision of vacuum insulation panels will reduce the gap between the refrigerator body and the refrigerator liner (i.e., the space for accommodating the insulation layer), thereby increasing the flow resistance of the foaming liquid in the box. When the operator injects the foaming liquid from the bottom of the box, this resistance makes it difficult for the foaming liquid to be evenly distributed throughout the refrigerator box (especially the top area of ​​the box), which leads to uneven foaming or even foaming failure, which not only affects the insulation performance of the refrigerator, but also reduces the overall yield of the product.

[0034] In order to solve the above-mentioned technical problems, the inventor innovatively designed the following technical solution, and the specific implementation solution of this application will be described in detail with reference to the accompanying drawings.

[0035] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the assembly of a refrigerator foaming and guiding device 1 provided in this embodiment. Figure 2 An exploded schematic diagram of a refrigerator foaming and guiding device 1 provided in this embodiment, Figure 3 The schematic diagram of the fixing seat 10 provided in the present embodiment. The refrigerator foaming and guiding device 1 comprises: a fixing seat 10, a baffle 20, a connecting piece 30 and a foaming bag 40, the fixing seat 10 comprises a fixing seat bottom 100 and a fixing seat side wall 110 enclosed around the fixing seat bottom 100, the fixing seat bottom 100 is provided with a through hole 1001 penetrating the fixing seat bottom 100, and the inner side of the fixing seat bottom 100 is also provided with a limiting hole 1002.

[0036] In this embodiment, the fixing seat 10 serves as the basis of the entire refrigerator foaming and guiding device 1 and plays a supporting role. The fixing seat 10 is usually fixed to the bottom of the refrigerator body.

[0037] See also Figure 3 , Figure 4 and Figure 5 , Figure 4 A schematic diagram of the baffle 20 provided in this embodiment, Figure 5 This is one of the schematic diagrams of the fixing seat 10 provided in this embodiment after being connected to the baffle 20. The baffle 20 includes a baffle body 200 and a baffle fixing portion 210 connected to the baffle body 200, the baffle fixing portion 210 is limited in the limiting hole 1002, the baffle body 200 can rotate relative to the fixing seat bottom 100 through the baffle fixing portion 210, and the baffle body 200 is used to cover the through hole 1001.

[0038] In this embodiment, the baffle fixing portion 210 includes a first baffle fixing portion 210a and a second baffle fixing portion 210b that are arranged opposite to each other, and the limiting hole 1002 on the inner side of the bottom 100 of the fixing seat should match the first baffle fixing portion 210a and the second baffle fixing portion 210b, that is, the limiting hole 1002 includes a first limiting hole 1002a that matches the first baffle fixing portion 210a and a second limiting hole 1002b that matches the second baffle fixing portion 210b. In this way, the baffle body 200 can rotate relative to the bottom 100 of the fixing seat through the first baffle fixing portion 210a and the second baffle fixing portion 210b, thereby realizing the closing and opening control of the through hole 1001. Specifically, when the refrigerator foaming operation is not performed or the foaming operation has been completed, the baffle body 200 is in the initial state, shielding the through hole 1001, ensuring the sealing of the refrigerator foaming guide device 1, and preventing foreign matter from entering or foaming liquid from leaking. When performing the refrigerator foaming operation, the operator inserts the injection gun (containing the foaming liquid) into the device from the through hole 1001, and at this time the baffle body 200 rotates to a certain angle to open the through hole 1001.

[0039] Please see again Figure 1 The connecting member 30 includes a first connecting interface 300 and a second connecting interface 310 which are arranged opposite to each other. The first connecting interface 300 is connected to the fixing seat 10. The foaming bag 40 includes a first bag opening 400 and a second bag opening 410 which are arranged opposite to each other. The first bag opening 400 is sleeved on the second connecting interface 310 of the connecting member 30.

[0040] In this embodiment, the connector 30 serves as a bridge between the fixing seat 10 and the foaming bag 40. When performing the refrigerator foaming operation, the operator inserts the injection gun from the through hole 1001, and the foaming liquid in the injection gun is filled into the foaming bag 40 by the connector 30, and flows from the first bag opening 400 to the second bag opening 410 under the guidance of the foaming bag 40. The foaming liquid is evenly distributed to the entire box from the second bag opening 410, and finally the foaming liquid forms a foam body with a certain density and strength, which is filled between the refrigerator box and the refrigerator liner as a heat preservation layer. In this way, the foaming liquid can be evenly distributed to the entire refrigerator box through the refrigerator foaming guide device 1, which significantly improves the overall yield of the product.

[0041] For further information, see Figure 3 , Figure 5 and Figure 6 , Figure 6 The second schematic diagram of the connection between the fixed seat 10 and the baffle 20 provided in this embodiment, the refrigerator foaming and deflection device 1 also includes an elastic member 50, the elastic member 50 includes an elastic part 500 and a rotating arm 510 connected to the elastic part 500, the elastic part 500 is fixed to the inner side of the bottom 100 of the fixed seat, and the rotating arm 510 is fixed to the baffle body 200.

[0042] In this embodiment, the inner side of the bottom 100 of the fixing seat includes a fixing column 1003 fixed to the elastic part 500, and the elastic part 500 is wound and connected with the fixing column 1003. The shape of the side of the rotating arm 510 away from the elastic part 500 includes an L shape, which supports and fixes the baffle body 200 by penetrating the baffle body 200. At this time, when the refrigerator foaming operation is required, the operator inserts the injection gun from the through hole 1001 of the bottom 100 of the fixing seat. With the insertion of the injection gun, the rotating arm 510 drives the baffle body 200 to rotate to a certain angle, so that the injection gun enters the refrigerator foaming guide device 1. After the foaming is completed, the operator removes the injection gun from the through hole 1001, and the elastic member 50 returns to the initial state under the elastic action, and then the rotating arm 510 connected to the elastic member 50 drives the baffle body 200 to return to the initial state. The baffle body 200 covers the through hole 1001 again to prevent the risk of foaming liquid backflow.

[0043] It is worth noting that the elastic member 50 can be a spring.

[0044] For further information, see Figure 1 and Figure 2 In this embodiment, the fixing seat side wall 110 is provided with a card interface 120, and the side wall of the connecting member 30 close to the first connecting interface 300 is provided with a protrusion 320, and the fixing seat 10 and the connecting member 30 are connected through the matching of the card interface 120 and the protrusion 320. In this way, the matching of the card interface 120 and the protrusion 320 can ensure the tight connection between the fixing seat 10 and the connecting member 30.

[0045] Further, please see again Figure 1 and Figure 2 In this embodiment, the cross-sectional shape of the bottom 100 of the fixing seat is rectangular, the cross-sectional shape of the connecting member 30 is also rectangular, the card interface 120 is arranged on the four fixing seat side walls 110 of the fixing seat 10, and the protrusion 320 is correspondingly arranged on the four side walls of the connecting member 30 close to the first connecting interface 300. In the direction from the first connecting interface 300 to the second connecting interface 310, the height of the protrusion 320 relative to the protrusion 320 of the corresponding side wall gradually increases. In this way, when installing the fixing seat 10 and the connecting member 30, the operator aligns the card interface 120 of the fixing seat 10 with the protrusion 320 of the fixing seat side wall 110, and then gradually pushes the connecting member 30, so that the card interface 120 of the fixing seat 10 gradually slides in along the direction of the increasing height of the protrusion 320 until the protrusion 320 is covered, thereby achieving the fixation of the fixing seat 10 and the connecting member 30.

[0046] For further information, see Figure 7 , Figure 7Schematic diagram of the foaming bag 40 provided in this embodiment. In this embodiment, the foaming bag 40 includes at least one opening 420, and the opening 420 is arranged near the first bag opening 400 of the foaming bag 40, and the distance D1 from the side of the opening 420 away from the first bag opening 400 to the first bag opening 400 ranges from 240 mm to 260 mm. For example, the distance D1 from the side of the opening 420 away from the bag opening to the first bag opening 400 is 240 mm, 245 mm, 250 mm, 255 mm and 260 mm, etc. In this way, a plurality of openings 420 are arranged in the middle of the foaming bag 40, and when the operator uses the injection gun to perform the foaming operation, the foaming liquid can flow into the entire box body through the second bag opening 410 of the foaming bag 40, and can also flow in through this opening 420, further ensuring the uniform distribution of the foaming liquid in the entire box body. In addition, by setting the opening 420, the rapid distribution of the foaming liquid in the entire box body can be ensured, and the foaming efficiency is improved.

[0047] The length D2 of the foaming bag 40 ranges from 950 mm to 980 mm. For example, the length D2 of the foaming bag 40 is 950 mm, 955 mm, 960 mm, 965 mm, 970 mm, 975 mm, and 980 mm, etc. In this embodiment, the length of the foaming bag 40 is related to the length of the entire box body. The length of the foaming bag 40 can be adjusted according to the length of the box body in the actual application scenario. For example, if the length of the foaming bag 40 is too short, the gap between the top of the foaming bag 40 and the top of the box body is too large, which may cause the foaming liquid to be unable to fill the top space of the box body during the foaming process, thereby affecting the uniformity of the foaming. For example, if the length of the foaming bag 40 is too long, the gap between the top of the foaming bag 40 and the top of the box is too small. Since the foaming bag 40 is made of flexible material, the foaming bag 40 may be squeezed or deformed near the top of the box. This may cause the foaming liquid flowing out of the second bag opening 410 to be obstructed when flowing toward the box, resulting in uneven distribution of the foaming liquid and affecting the foaming effect.

[0048] For further information, see Figure 7 In this embodiment, the number of openings 420 is multiple, and the multiple openings 420 are arranged on opposite sides of the foaming bag 40. In this way, the openings 420 are evenly distributed on both sides of the foaming bag 40, ensuring that during the foaming process, the foaming liquid evenly enters the corresponding boxes on both sides of the foaming liquid through the openings 420, thereby improving the uniformity and consistency of the foaming effect.

[0049] The size of the opening 420 ranges from 15 mm to 20 mm. For example, the size D3 of the opening 420 is 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm. In this embodiment, the size of the opening 420 can be adjusted according to the size of the foaming bag 40. For example, when the size of the foaming bag 40 is large, the size of the opening 420 provided on the foaming bag 40 can be correspondingly increased to speed up the speed at which the foaming liquid flows into the box body and improve the foaming efficiency. For example, when the size of the foaming bag 40 is relatively small, the size of the opening 420 provided on the foaming bag 40 can be appropriately reduced to achieve a more efficient and uniform foaming effect.

[0050] For further information, see Figure 1 In this embodiment, the foaming bag 40 is made of a flexible material, so that the first bag opening 400 of the foaming bag 40 can adapt to the volume change of the second connecting port of the connecting piece 30 and maintain good sealing performance during the foaming process. The foaming bag 40 is sleeved on the connecting piece 30, and is flat and extends from the bottom of the box to the top of the box. During the foaming operation, if the connection between the first bag opening 400 of the foaming bag 40 and the second connecting interface 310 is not firm enough, the foaming liquid can easily flow out of the refrigerator foaming guide device 1 through the gap between the first bag opening 400 of the foaming bag 40 and the second connecting interface 310, which may cause uneven foaming effect. Therefore, it is necessary to ensure that the first bag opening 400 of the foaming bag 40 is sealed and sleeved on the second connecting interface 310 to prevent the foaming liquid from leaking and ensure the smooth progress of the foaming process. Exemplarily, the first bag opening 400 and the second connection interface 310 may be sealed by bonding, or by wrapping an adhesive (eg, tape) around a side of the first bag opening 400 away from the second connection interface 310 .

[0051] Exemplarily, the foaming bag 40 comprises a nylon woven bag. The nylon woven bag has high strength, wear resistance and good flexibility, and can not only withstand the pressure when the foaming liquid is injected, but also maintain a stable shape during the foaming process.

[0052] For further information, see Figure 1 and Figure 3 In this embodiment, the bottom 100 of the fixing seat and the side wall 110 of the fixing seat of the refrigerator foaming and guiding device 1 enclose a receiving space 60, and the first connection interface 300 of the connecting member 30 is embedded in the receiving space 60. In this way, the connecting member 30 is tightly connected with the fixing seat 10, so as to prevent the foaming liquid from leaking during the injection process, ensure the sealing and stability of the refrigerator foaming and guiding device 1, and ensure the smooth progress of the foaming process.

[0053] For further information, see Figure 1In this embodiment, the refrigerator foaming and deflecting device 1 also includes a fixing through hole 70 provided on the side wall 110 of the fixing seat. The fixing through hole 70 is used to fix the refrigerator foaming and deflecting device 1 to the bottom of the box. At the same time, the bottom of the box includes a refrigerator fixing through hole corresponding to the fixing through hole 70. The refrigerator fixing through hole and the inner wall of the fixing through hole 70 both have threads. The refrigerator foaming and deflecting device 1 can be fixed to the bottom of the box by the cooperation of the fixing through hole 70 and the refrigerator fixing through hole through the threads. After the foaming is completed, the refrigerator foaming and deflecting device 1 finally stays in the refrigerator without the need for disassembly operation, which optimizes the operation process and improves work efficiency.

[0054] It is worth noting that the fixing member may be a screw.

[0055] Based on the same inventive concept, another object of the present application is to provide a refrigerator, comprising a box body, an inner tank located in the box body, and any one of the aforementioned refrigerator foaming and diversion devices 1, wherein the fixing seat 10 is fixed to the bottom of the box body, and the foaming bag 40 is located in the gap between the box body and the inner tank. Exemplarily, the foaming bag 40 can be laid flat on the surface of the box body or the inner tank and fixed thereto by adhesive.

[0056] In this embodiment, the fixing seat 10 can be connected to the bottom of the box body by screws, welding or other fixing methods. When the refrigerator foaming process is performed, first, the refrigerator foaming guide device 1 is installed at the bottom of the refrigerator, and the foaming bag 40 is flat and extends from the bottom of the box body to the top of the box body. Then, the operator inserts the injection gun (containing the foaming liquid) into the device from the through hole 1001 to inject the foaming liquid. During this process, the rotating arm 510 drives the baffle body 200 to rotate to a certain angle to provide a channel for the injection gun. The foaming liquid in the injection gun fills the foaming bag 40 through the connecting piece 30, and flows into the box body through the openings 420 on both sides of the foaming bag 40 and the second bag opening 410, so as to achieve uniform distribution of the foaming liquid in the entire box body. After the injection is completed, the operator removes the injection gun from the device, and the rotating arm 510 immediately drives the baffle body 200 to reset, automatically blocking the through hole 1001, without the need for manual plugging operations, simplifying the operation process.

[0057] Eventually, the foaming liquid solidifies between the refrigerator body and the inner tank, forming a uniform insulation layer, improving the overall yield of the refrigerator.

[0058] In summary, the present application provides a refrigerator foaming and diversion device and a refrigerator. The refrigerator foaming and diversion device includes: a fixed seat, a baffle, a connecting piece and a foaming bag. The fixed seat includes a fixed seat bottom and a fixed seat side wall enclosed around the fixed seat bottom. The fixed seat bottom is provided with a through hole penetrating the fixed seat bottom, and the inner side of the fixed seat bottom is also provided with a limiting hole. The baffle includes a baffle body and a baffle fixing portion connected to the baffle body. The baffle fixing portion is limited in the limiting hole. The baffle body can be rotated relative to the fixed seat bottom through the baffle fixing portion, and the baffle body is used to block the through hole. The connecting piece includes a first connecting interface and a second connecting interface arranged oppositely, and the first connecting interface is connected to the fixed seat. The foaming bag includes a first bag opening and a second bag opening arranged oppositely, and the first bag opening is sleeved on the second connecting interface of the connecting piece. In this way, during foaming, the foaming liquid can be directed to different positions through the foaming bag, so that the foaming liquid is evenly distributed to the space in the entire refrigerator body for accommodating the insulation layer, and the insulation layer is formed in the space through foaming of the foaming liquid, thereby ensuring the thermal insulation performance of the product and improving the overall yield of the product.

[0059] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
