Description

Technical Field

[0001] This invention relates to the field of electrical appliances, and more particularly to an auxiliary injection structure, a method for manufacturing a refrigeration device, and the refrigeration device itself. Background Technology

[0002] In daily life, refrigerators are indispensable appliances for storing and preserving food. To store as much food as possible, users tend to choose refrigerators with large capacities. Currently, there are two ways to increase refrigerator capacity: one is to simply increase the overall size of the refrigerator, and the other is to increase the volume ratio. Comparatively, refrigerators with larger volume ratios are more popular with users.

[0003] One way to increase the volume ratio of a refrigerator is to reduce the thickness of the foam layer by filling it with a thinner foam material that has good insulation properties. However, this type of foam material has poor flowability and is prone to uneven filling. Furthermore, due to the thinness of the foam layer, the internal pressure is relatively high when the foam material is injected, which can easily lead to overflow after injection. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary injection structure, a manufacturing method for a refrigeration device, and a refrigeration device, the purpose of which is to prevent the foamed material from overflowing after injection.

[0005] To achieve the above objectives, the present invention provides an auxiliary injection structure for assisting the injection gun in injecting foaming material into the foaming layer of a refrigeration device, comprising a base, a flow guide, and a baffle.

[0006] The flow guide is made of a flexible material and has a flow guide cavity formed therein. The flow guide cavity extends through the flow guide and includes an open first port and a second port.

[0007] The flow guide is connected to one side of the base, and the base is provided with an injection port for connecting the first port. The baffle is rotatably connected to the base and includes a first position that closes the injection port and a second position that opens the injection port after rotating from the first position into the flow guide cavity.

[0008] The guide member includes a supporting portion protruding from its inner wall surface. When the baffle is in the first position, the supporting portion abuts against the baffle. When the baffle rotates from the first position to the second position, the supporting portion moves and / or deforms.

[0009] As a further improvement of the present invention, the rotation axis of the baffle is located on the side of the base near the flow guide. When the baffle is in the first position, at least a portion of the base abuts against the side of the baffle facing the base, so as to restrict the baffle from rotating out of the flow guide cavity.

[0010] As a further improvement of the present invention, the baffle includes a first baffle and a second baffle, and the abutting part includes a first abutting part for abutting the first baffle and a second abutting part for abutting the second baffle.

[0011] As a further improvement of the present invention, the guide includes a contracted state and an expanded state after expanding from the contracted state. When the guide is in the contracted state, the area of ​​the second port is smaller than the area of ​​the first port.

[0012] As a further improvement of the present invention, the flow guiding cavity includes a first chamber communicating with the second port, the first chamber being extended in a curved shape.

[0013] As a further improvement of the present invention, the flow guiding cavity further includes a second chamber communicating with the first port. The second chamber is connected to the first chamber, and the width of the second chamber gradually decreases in the direction close to the first chamber.

[0014] As a further improvement of the present invention, the auxiliary injection structure further includes a flow guide tube connected to the flow guide member, and the second port communicates with the interior of the flow guide tube.

[0015] The present invention also provides a method for manufacturing a refrigeration device, the refrigeration device comprising a housing, an inner liner located within the housing, and a foam layer formed between the housing and the inner liner, the manufacturing method comprising the following steps:

[0016] Provide an auxiliary injection structure as described in any one of claims;

[0017] The base is connected to the housing, and the second port extends into the foam layer;

[0018] A material gun is provided, which is used to push the baffle from the first position to the second position. Then, foaming material is injected into the foaming layer through the flow guide cavity.

[0019] After the material is injected, the material gun exits the guide cavity. During the process of the material gun exiting the guide cavity, the baffle returns from the second position to the first position under the action of the supporting part.

[0020] As a further improvement of the present invention, the inner liner includes a first inner liner and a second inner liner located above the first inner liner, the box body includes a bottom plate located below the first inner liner, the auxiliary injection structure further includes a guide pipe connected to the guide member, and the second port communicates with the interior of the guide pipe; the manufacturing method further includes the following steps:

[0021] Before injecting the foaming material into the foaming layer, the guide tube extends from the guide member to the second inner liner.

[0022] The present invention also provides a refrigeration device, which includes the above-described auxiliary filling structure.

[0023] Beneficial effects:

[0024] When the auxiliary injection structure provided by this invention is installed on the housing of the refrigeration equipment, when it is necessary to inject foaming material into the foaming layer, the injection gun pushes the baffle from the first position to the second position to enter the guide cavity. The injection gun can also expand the guide component, making the size of the second port larger, thereby facilitating the injection of material into the foaming layer. After the injection is completed, the injection gun exits the guide cavity, the guide component contracts, the size of the second port becomes smaller, and the baffle will automatically close under the action of the supporting part. In this way, the foaming material in the foaming layer is not easy to flow into the guide cavity from the second port. Even if a small amount of foaming material flows into the guide cavity, it will not overflow from the injection port. Attached Figure Description

[0045] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0046] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0047] One embodiment of the present invention provides a refrigeration device 100, such as... Figure 1-2As shown, the refrigeration equipment 100 includes a cabinet 10 and an inner liner 20 located inside the cabinet 10. The inner liner 20 surrounds and forms a compartment 201 for storing food. The refrigeration equipment 100 also includes a refrigeration system for cooling the compartment 201. Food stored in the low-temperature environment of the compartment 201 can be kept fresh and prevented from spoiling.

[0048] The aforementioned inner liner 20 is disposed inside the housing 10 and spaced apart from the housing 10 to form a foam layer 30 located between the housing 10 and the inner liner 20. To insulate the inner liner 20 and reduce the leakage of cold air from the compartment 201, during the manufacturing process of the refrigeration equipment 100, a foaming material with heat-insulating properties is injected into the foam layer 30 through a material gun. After the foaming material foams within the foam layer 30, it will envelop the inner liner 20 to reduce heat exchange between the inside and outside of the inner liner 20.

[0049] The refrigeration unit 100 also includes a door for opening and closing the compartment 201. Specifically, the door is hinged to the housing 10 so that it can rotate relative to the housing 10. The user opens and closes the compartment 201 by turning the door. When it is necessary to store food in the compartment 201 or to remove food from the compartment 201, the user turns the door to open the compartment 201. When the compartment 201 is closed, it is essentially sealed, and the user cannot access or remove items.

[0050] To assist the material gun in injecting the foaming material into the foaming layer 30, such as Figure 3-10 As shown, an embodiment of the present invention provides an auxiliary injection structure 40, which includes a base 1, a flow guide 2, and a baffle 3.

[0051] The flow guide 2 is made of a flexible material that can deform elastically. A flow guide cavity 21 is formed inside the flow guide 2. The flow guide cavity 21 is disposed through the flow guide 2 and includes an open first port 211 and a second port 212. The first port 211 and the second port 212 connect the inside and outside of the flow guide cavity 21.

[0052] The flow guide 2 is connected to one side of the base 1. The base 1 is provided with an injection port 11 for connecting to the first port 211. The baffle 3 is rotatably connected to the base 1 and includes a first position that closes the injection port 11 (e.g., Figure 9 As shown), after rotating from the first position into the guide cavity 21, the second position (as shown) opens the injection port 11. Figure 10 (As shown). The baffle 3 switches between the first position and the second position, which allows the injection port 11 to open and close.

[0053] The flow guide 2 includes a supporting portion 22 protruding from its inner wall surface. As part of the flow guide 2, the supporting portion 22 can move and / or deform when subjected to external force. When the baffle 3 is in the first position, the supporting portion 22 supports the baffle 3. When the baffle 3 is subjected to external force and rotates from the first position to the second position, the supporting portion 22 will move and / or deform under the action of the baffle 3, thereby accumulating elastic potential energy. When the external force is no longer applied to the baffle 3, the supporting portion 22 tends to return to its original position. Under the action of the supporting portion 22, the baffle 3 will return from the second position to the first position, thereby closing the injection port 11.

[0054] When injecting foaming material into the foaming layer 30 of the refrigeration equipment 100, the aforementioned auxiliary injection structure 40 can be first connected to the housing 10 of the refrigeration equipment 100, with the second port 212 extending into the foaming layer 30. Then, the baffle 3 is pushed open from the first position to the second position using a material gun, allowing the head of the material gun to extend into the guide cavity 21. Thus, the foaming material sprayed outwards by the material gun will flow out of the guide cavity 21 through the second port 212 and enter the foaming layer 30. When the material gun pushes the baffle 3 open from the first position to the second position, the supporting part 22 will move and / or deform. After injection, the material gun withdraws from the guide cavity 21. During this withdrawal, the baffle 3 returns from the second position to the first position under the action of the supporting part 22. At this time, the injection port 11 closes, and the foaming material in the foaming layer 30 is less likely to overflow from the injection port 11.

[0055] After the auxiliary injection structure 40 provided in this embodiment is installed on the housing 10 of the refrigeration equipment 100, when it is necessary to inject foaming material into the foaming layer 30, the material gun pushes the baffle 3 from the first position to the second position to enter the guide cavity 21. The material gun can also expand the guide member 2, making the size of the second port 212 larger, thereby facilitating the material gun to inject material into the foaming layer 30. After the injection is completed, the material gun exits the guide cavity 21, the guide member 2 contracts, the size of the second port 212 becomes smaller, and the baffle 3 will automatically close under the action of the holding part 22. In this way, the foaming material in the foaming layer 30 is not easy to flow into the guide cavity 21 from the second port 212. Even if a small amount of foaming material flows into the guide cavity 21, it will not overflow from the injection port 11.

[0056] As can be seen, the guide member 2, made of flexible material, can expand and contract, making the size of the second port 212 larger during injection to facilitate the injection of material into the foaming layer 30 by the material gun. When the material gun is withdrawn, the size of the second port 212 becomes smaller to restrict the foaming material of the foaming layer 30 from entering the guide cavity 21. On the other hand, the abutment part 22 on the guide member 2 can be reset when the material gun is withdrawn and drive the baffle 3 to close automatically, thereby further preventing the foaming material from overflowing from the injection port 11.

[0057] The auxiliary injection structure 40 provided in this embodiment is suitable for installation on a refrigeration device 100 with a large volume ratio and a thin foam layer 30, to inject foaming material into the foam layer 30 of the large volume ratio refrigeration device 100 using an auxiliary injection gun. Because the foam layer 30 of the large volume ratio refrigeration device 100 is thin, the pressure inside the foam layer 30 is relatively high when the foaming material is injected, making it easier for the foaming material to overflow. The auxiliary injection structure 40 provided in this embodiment can effectively prevent the foaming material from overflowing from the foam layer 30.

[0058] In this embodiment, the rotation axis of the baffle 3 is located on the side of the base 1 near the guide member 2. When the baffle 3 is in the first position, at least part of the base 1 abuts against the side of the baffle 3 facing the base 1. Thus, when the baffle 3 is in the first position, it can only rotate inside the guide cavity 21 and cannot rotate outside the guide cavity 21.

[0059] The baffle 3 includes a first baffle 3a and a second baffle 3b, which are arranged in a counter-position and work together to open and close the injection port 11. Both the first baffle 3a and the second baffle 3b have a first position and a second position. When both the first baffle 3a and the second baffle 3b are in the first position, the injection port 11 is closed; when both the first baffle 3a and the second baffle 3b are in the second position, the injection port 11 is open.

[0060] Understandably, when the above-mentioned baffle 3 is in the first position, it should be understood that both the first baffle 3a and the second baffle 3b are in the first position; when the above-mentioned baffle 3 is in the second position, it should be understood that both the first baffle 3a and the second baffle 3b are in the second position.

[0061] Corresponding to the first baffle 3a and the second baffle 3b, the abutting part 22 includes a first abutting part 22a for abutting the first baffle 3a and a second abutting part 22b for abutting the second baffle 3b. When the first baffle 3a is in the first position, the first abutting part 22a abuts against the first baffle 3a. When the first baffle 3a rotates from the first position to the second position, the first abutting part 22a moves and / or deforms. When the second baffle 3b is in the first position, the second abutting part 22b abuts against the second baffle 3b. When the second baffle 3b rotates from the first position to the second position, the second abutting part 22b moves and / or deforms.

[0062] It is conceivable that the number of baffles 3 is not limited to two; for example, it could be one or three.

[0063] The base 1 includes a substrate 13 and a protruding ring 14 formed from the side of the substrate 13 near the flow guide 2. The injection port 11 is opened on the substrate 13, and the protruding ring 14 is arranged around the injection port 11. The shape of the protruding ring 14 matches the shape of the first port 211. When the flow guide 2 is connected to the base 1, the protruding ring 14 extends into the flow guide cavity 21 from the first port 211, and the flow guide 2 surrounds the protruding ring 14.

[0064] To increase the reliability of the connection between the base 1 and the guide member 2, a buckle 15 is formed on the protruding ring 14, and a groove 23 matching the buckle 15 is formed on the guide member 2. When the guide member 2 is connected to the base 1, the buckle 15 is engaged in the groove 23.

[0065] It is conceivable that the base 1 and the guide 2 can be connected by other forms of connection structures, not limited to the above-mentioned schemes.

[0066] The flow guide 2 includes a contracted state and an expanded state after expanding from the contracted state. During the transition from the contracted state to the expanded state, the volume of the flow guide cavity 21 tends to increase. When the auxiliary injection structure 40 assists the material gun in injection, when the material gun extends into the flow guide cavity 21, it forces the flow guide 2 to transition from the contracted state to the expanded state, thereby increasing the volume of the flow guide cavity 21 and the area of ​​the second port 212. After the material gun finishes injection, it withdraws from the flow guide cavity 21, and the flow guide 2 transitions from the expanded state to the contracted state, thereby reducing the volume of the flow guide cavity 21 and the area of ​​the second port 212.

[0067] When the guide member 2 is in a contracted state, the area of ​​the second port 212 is smaller than the area of ​​the first port 211. The second port 212 is flat and its area is designed to be small, which is not conducive to the foaming material in the foaming layer 30 flowing back into the guide layer from the second port 212. The first port 211 is designed to be larger, which makes it easier for the material gun to extend into the guide cavity 21.

[0068] The flow guiding cavity 21 includes a first chamber 213 communicating with the second port 212, and the first chamber 213 extends in a curved shape. Compared to a straight extension, the foaming material needs to travel a longer distance and consume more time when flowing through the curved first chamber 213, and the curved structure of the first chamber 213 is also not conducive to the flow of the foaming material within it. Thus, even if the foaming material enters the flow guiding cavity 21 from the second port 212, it cannot completely flow through the second chamber.

[0069] The flow guide cavity 21 also includes a second chamber 214 connected to the first port 211. The first chamber 213 and the second chamber 214 are connected. The cross-section of the second chamber 214 is approximately triangular prism-shaped. In the direction close to the first chamber 213, the width of the second chamber 214 gradually decreases. That is, the closer to the first chamber 214, the smaller the width of the second chamber 213. During material injection, the material gun first enters the second chamber 214 and then enters the first chamber 213. The above arrangement is beneficial for the material gun to open the flow guide 2.

[0070] The inner liner 20 includes a first inner liner 20a and a second inner liner 20b located above the first inner liner 20a. The first inner liner 20a forms a first compartment 201a, and the second inner liner 20b forms a second compartment 201b. In this embodiment, depending on the set refrigeration temperature, the first compartment 201a may be a freezer compartment 201, and the second compartment 201b may be a refrigerator compartment 201.

[0071] The housing 10 includes a bottom plate 101 located below the first inner liner 20a. This bottom plate 101 is commonly referred to as the bottom steel. When the foaming layer 30 is injected, the base 1 is connected to the bottom plate 101. Because the injection position (i.e., at the bottom plate 101) is far from the upper side of the second inner liner 20b, the foaming material enters the foaming layer 30 directly from the bottom plate 101 and has difficulty flowing to the upper side of the second inner liner 20b, thus affecting the insulation effect of the second inner liner 20b. To address this, the auxiliary injection structure 40 also includes a guide pipe 4 connected to the guide member 2. The second port 212 communicates with the interior of the guide member 2. The guide pipe 4 extends from the guide member 2 to the second inner liner 20b, and more specifically, to the upper side of the second inner liner 20b. When the injection gun injects the material, the foaming material can flow along the guide pipe 4 to the upper side of the second inner liner 20b, and then flow into the foaming cavity.

[0072] As can be imagined, the guide tube 4 can also extend from the guide member 2 to other locations of the foam layer 30, thereby guiding the foam material to other locations during injection.

[0073] The guide tube 4 can be tied to the periphery of the guide member 2 by an elastic band. The second port 212 of the guide member 2 extends into the interior of the guide tube 4. The guide tube 4 is made of flexible material. When the guide member 2 contracts, the guide tube 4 and the elastic band contract together. When the guide member 2 expands, the guide tube 4 and the elastic band expand together.

[0074] The present invention also provides a method for manufacturing a refrigeration device 100, the method comprising the following steps:

[0075] S1. Connect the base 1 to the housing 10 and extend the second port 212 into the foam layer 30.

[0076] S2. Provide a material gun and use the material gun to push the baffle 3 from the first position to the second position. Then, inject foaming material into the foaming layer 30 through the guide cavity 21.

[0077] In step S2, after the material gun pushes the baffle 3 from the first position to the second position, the head of the material gun will extend into the guide gun through the injection port 11 and the first port 211. The foaming material sprayed out by the material gun will flow out of the guide cavity 21 through the second port 212 and thus flow into the foaming layer 30. When the material gun pushes the baffle 3 from the first position to the second position, the supporting part 22 will move and / or deform.

[0078] S3. After the material injection is completed, the material gun exits the guide cavity 21. During the process of the material gun exiting the guide cavity 21, the baffle 3 returns from the second position to the first position under the action of the supporting part 22.

[0079] In step S3, after the baffle 3 returns from the second position to the first position, the injection port 11 is closed, and the foaming material in the foaming layer 30 will not overflow from the injection port 11.

[0080] S4. Before injecting foaming material into the foaming layer 30, extend the guide tube 4 from the guide member 2 to the second inner liner 20b.

[0081] In step S4, the guide pipe 4 can be extended to the upper side of the second inner liner 20b. The foaming material can flow through the guide pipe 4 to the upper side of the second inner liner 20b and then enter the foaming layer 30. In this way, it can be ensured that after the foaming is completed, the second inner liner 20b can be completely and fully surrounded by the foaming material, thereby ensuring the heat preservation effect of the second inner liner 20b.

[0082] It should be noted that S1-S4 above are used as reference numerals only and do not strictly represent the execution steps of the manufacturing method of the refrigeration equipment provided in this embodiment.

[0083] After the above steps are completed, once the foaming material has finished foaming, the auxiliary injection structure 40 will remain on the refrigeration device 100. Therefore, the present invention also provides a refrigeration device 100, which is manufactured by the above manufacturing method and includes the above auxiliary injection structure 40.

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.
