Detailed Implementation

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0028] Please see Figure 1 This application provides an insulated door panel 100 and an ice-making device 1000 equipped with the insulated door panel 100. In this embodiment, the ice-making device 1000 is a device with storage and ice-making functions. In this embodiment, the ice-making device 1000 includes a cabinet 900, a refrigeration system 200, and an insulated door panel 100. The cabinet 900 is provided with a storage space 910 for storing water and prepared ice cubes, etc. The insulated door panel 100 is rotatably connected to the cabinet 900 so as to expose or cover the storage space 910. In this embodiment, the refrigeration system 200 may include an evaporator, a compressor, and a condenser (not shown in the figure). The evaporator, compressor, and condenser are connected end-to-end to form a circulation channel. Refrigerant flows within the circulation channel. Under the compression action of the compressor, the refrigerant is in a high-pressure, low-temperature state and flows to the evaporator. The evaporator cooperates with the ice mold of the ice-making device 1000 to lower the temperature of the ice mold. Subsequently, the refrigerant flows to the condenser to dissipate the absorbed heat to the outside of the ice-making device 1000, and then flows back to the compressor for the next cycle. As water flows through the ice mold, the water remains inside the ice mold and freezes into ice blocks, thus completing the preparation of ice blocks.

[0029] In this embodiment, the insulated door panel 100 is rotatably mounted on the cabinet 900. Specifically, the ice-making device 1000 in this embodiment also includes a hinge assembly 40, which can cooperate with the structure of the cabinet 900 and the insulated door panel 100 to achieve a rotatable connection between the cabinet 900 and the insulated door panel 100. In some other embodiments, the insulated door panel 100 and the cabinet 900 can be rotatably connected by hinges. In some other embodiments, the ice-making device 1000 may include a linkage structure connecting the cabinet 900 and the insulated door panel 100, and the insulated door panel 100 can move relative to the cabinet 900 through the linkage structure to expose or cover the storage space 910.

[0030] Please see Figure 2 and Figure 3 In this embodiment, the insulated door panel 100 includes an inner shell 10 and an outer shell 20. The outer shell 20 and the inner shell 10 are fastened together to form the main structure of the insulated door panel 100. The insulated door panel 100 has a hollow interior for filling with insulation material. Specifically, in this embodiment, the inner shell 10 includes an inner shell body 11 and a first fastening part 12, and the outer shell 20 includes an outer shell body 21 and a second fastening part 22. At least a portion of the inner shell body 11 is spaced apart from the outer shell body 21 to form a receiving cavity 60. In this embodiment, the insulated door panel 100 also includes an insulation layer 70, which is disposed within the receiving cavity 60. The first fastening part 12 is connected to the side of the inner shell 10 facing the receiving cavity 60, and the second fastening part 22 is connected to the side of the outer shell body 21 facing the receiving cavity 60. In practical applications, the second fastening part 22 engages with the first fastening part 12 to detachably connect the inner shell body 11 to the outer shell body 21. When the outer shell body 21 and the inner shell body 11 are engaged, the first fastening part 12 and the second fastening part 22 are located within the receiving cavity 60 and are fastened together within the receiving cavity 60. In this embodiment, the insulation layer 70 includes foam plastic, mineral wool, etc.

[0031] In this embodiment, the insulated door panel 100 further includes a fastening connector 30, which is connected between the outer shell body 21 and the inner shell body 11 to restrict the movement of the outer shell body 21 relative to the inner shell body 11, prevent the second fastening part 22 from disengaging from the first fastening part 12, and ensure the stability of the connection between the inner shell 10 and the outer shell 20. In this embodiment, the fastening connector 30 can be located on the side where the insulated door panel 100 is rotatably connected to the cabinet 900, so that the position of the fastening connector 30 on the insulated door panel 100 is relatively concealed and not easily observed, thus making the appearance of the insulated door panel 100 simple and beautiful.

[0032] In summary, in this embodiment, the outer shell body 21 and the inner shell body 11 are initially detachably connected through the first fastening part 12 and the second fastening part 22, and then the outer shell body 21 and the inner shell body 11 are fixedly connected by the fastening connector 30 to complete the fixed connection between the outer shell 20 and the inner shell 10. The fastening connector 30 can restrict the movement of the outer shell body 21 relative to the inner shell body 11 to prevent the first fastening part 12 and the second fastening part 22 from separating, thereby improving the stability of the connection relationship between the outer shell 20 and the inner shell 10.

[0033] In this embodiment, the first fastening part 12 and the second fastening part 22 are located within the receiving cavity 60 of the heat-insulating door panel 100, and the fastening structure has minimal impact on the aesthetics of the outer surface of the heat-insulating door panel 100. In this embodiment, the fastening structure can effectively connect the outer shell 20 and the inner shell 10. On the one hand, it can reduce the use of fastening connectors 30, avoid setting too many fastening connectors 30 on the heat-insulating door panel 100, and avoid exposing the structure of too many fastening connectors 30 on the outer surface of the heat-insulating door panel 100, making the outer surface of the heat-insulating door panel 100 simpler and more aesthetically pleasing. On the other hand, the fastening process of the fastening structure is relatively simple, greatly simplifying the steps of assembling the heat-insulating door panel 100 and improving assembly efficiency.

[0034] In this embodiment, the inner shell 10 includes a plurality of first fastening portions 12, and the outer shell 20 includes a plurality of second fastening portions 22. A plurality of first fastening portions 12 are disposed on the edge of the inner shell body 11, and a plurality of first fastening portions 12 are disposed on the side of the inner shell body 11 facing the receiving cavity 60 and located at the center of the inner shell body 11. The plurality of first fastening portions 12 located at the center of the inner shell body 11 are spaced apart from the edge of the inner shell body 11. Correspondingly, a plurality of second fastening portions 22 are disposed on the edge of the outer shell body 21, and a plurality of second fastening portions 22 are disposed on the side of the outer shell body 21 facing the receiving cavity 60 and located at the center of the outer shell body 21. The plurality of second fastening portions 22 located at the center of the outer shell body 21 are spaced apart from the edge of the outer shell body 21. In this embodiment, the center of the inner shell body 11 should be understood as the area near the geometric center of the inner shell body 11, and the center of the outer shell body 21 should be understood as the area near the geometric center of the outer shell body 21. In this embodiment, the connection points between the outer shell 20 and the inner shell 10 are distributed more widely, thereby improving the stability of the connection between the outer shell 20 and the inner shell 10.

[0035] In this embodiment, when the insulation layer 70 is disposed in the receiving cavity 60, a plurality of first fastening portions 12 located at the edge of the inner shell body 11 are arranged around the outer periphery of the insulation layer 70, and a plurality of second fastening portions 22 located at the edge of the outer shell body 21 are arranged around the outer periphery of the insulation layer 70 to avoid the insulation layer 70. In this embodiment, the insulation layer 70 is provided with avoidance through holes 71 penetrating both opposite sides of the insulation layer 70. When the insulation layer 70 is disposed in the receiving cavity 60, the first fastening portion 12 located at the middle of the inner shell body 11 and the second fastening portion 22 located at the middle of the outer shell body 21 are embedded in the avoidance through holes 71 of the insulation layer 70 and fasten to each other. In this embodiment, the size of the avoidance through holes 71 is relatively large, and the shapes of the two ends of the avoidance through holes 71 are adaptively set according to the first fastening portion 12 and the second fastening portion 22, respectively, to sufficiently accommodate the movement of the first fastening portion 12 and the second fastening portion 22 within the avoidance through holes 71 and achieve fastening. In this embodiment, multiple through holes 71 are provided to correspond to and avoid multiple first fastening parts 12 and second fastening parts 22 located in the middle position.

[0036] Please see Figure 4 and Figure 5 In this embodiment, the first fastening part 12 includes a first latch 121. At least a portion of the structure of the first latch 121 is spaced apart from the inner shell body 11, and the first latch 121 and the inner shell body 11 together define an insert groove 123. Specifically, the first latch 121 extends in a direction generally parallel to the inner surface of the inner shell body 11. One end of the first latch 121 is connected to the inner shell body 11, and the other end is spaced apart from the inner shell body 11 to define the insert groove 123, which is used for the second fastening part 22 to be inserted.

[0037] In this embodiment, the first fastening part 12 further includes a reinforcing rib 122, which connects the first buckle 121 and the inner shell body 11. Specifically, one side of the reinforcing rib 122 is connected to the inner shell body 11, and the other side is connected to one side of the first buckle 121 in its extending direction. The reinforcing rib 122 is located on one side of the embedding groove 123 in the extending direction of the first buckle 121, so as to improve the enclosure degree of the embedding groove 123 and improve the stability of the connection relationship between the first fastening part 12 and the second fastening part 22.

[0038] In this embodiment, the reinforcing rib 122 has a plate-like structure and connects between the inner shell body 11 and the first buckle 121 to cover part of the opening of the embedding groove 123. In practical applications, the reinforcing rib 122 can abut against the second fastening part 22 to limit the second fastening part 22 from shifting to the left or right sides of the first buckle 121 in the extending direction or from disengaging from the embedding groove 123, thereby improving the stability of the fastening relationship between the first fastening part 11 and the second fastening part 22. As an example, there is one reinforcing rib 122, located on one side of the embedding groove 123 in the extending direction of the first buckle 121. As another example, there are two reinforcing ribs 122, located on both sides of the embedding groove 123 in the extending direction of the first buckle 121, so that the embedding groove 123 is a blind hole-like groove, which greatly improves the connection stability between the embedding groove 123 and the second fastening part 22. In other embodiments, the reinforcing rib 122 has a short and thin structure, and the number of reinforcing ribs 122 can be multiple, with multiple reinforcing ribs 122 respectively disposed on both sides of the embedding groove 123 in the extension direction of the first buckle 121.

[0039] Please see Figure 6 In this embodiment, the second fastening part 22 includes an extension part 221 and a connecting part 222. The connecting part 222 connects the outer shell body 21 and the extension part 221. One end of the extension part 221 is connected to the connecting part 222, and the other end is spaced apart from the outer shell body 21. When the outer shell 20 and the inner shell 10 are connected, the extension direction of the extension part 221 is approximately parallel to the extension direction of the first buckle 121. The extension part 221 can be embedded in the embedding groove 123 to complete the fastening connection between the first fastening part 12 and the second fastening part 22.

[0040] In this embodiment, the ice-making device 1000 is set on a roughly horizontal application platform, and the upward and downward directions are determined based on the horizontal application platform. When the insulated door panel 100 covers the storage space 910, the extension direction of the first buckle 121 is roughly upward, and the extension direction of the extension 221 is roughly downward. Therefore, the outer shell 20 is essentially suspended on the inner shell 10. In this embodiment, the dimension of the connecting part 222 near the outer shell body 21 is larger than the dimension of the connecting part 222 near the extension 221. This increases the stress area between the connecting part 222 and the outer shell body 21, prevents deformation of the outer shell body 21, improves the connection stability between the second fastening part 22 and the outer shell body 21, and increases the strength of the connecting part 222, preventing deformation or breakage of the connecting part 222.

[0041] Please see Figure 1In this embodiment, the cabinet 900 is provided with a hinge portion 920, which is structurally fitted with the insulated door panel 100. A hinge assembly 40 is connected between the hinge portion 920 and the insulated door panel 100 to allow the insulated door panel 100 to rotate relative to the cabinet 900. For details, please refer to... Figure 7 In this embodiment, the inner shell body 11 is recessed towards the receiving cavity 60 on the side opposite to the receiving cavity 60 to define a hinge groove 14. The hinge groove 14 is used to accommodate the hinge portion 920 on the cabinet 900, and at least a portion of the structure of the hinge portion 920 is rotatably embedded in the hinge groove 14. When the insulated door panel 100 is rotatably mounted on the cabinet 900, the hinge assembly 40 passes through the hinge portion 920, and both ends of the hinge assembly 40 pass through the groove wall of the hinge groove 14 to connect the inner shell body 11 and the hinge portion 920. In this embodiment, the main body structure of the hinge groove 14 is generally located inside the receiving cavity 60, and both ends of the hinge assembly 40 pass through the main body structure of the hinge groove 14 and extend into the receiving cavity 60, so as to hide both ends of the hinge assembly 40 inside the insulated door panel 100 and improve the aesthetics of the outer surface of the insulated door panel 100. In this embodiment, when the insulated door panel 100 is rotatably mounted on the cabinet 900, the hinge groove 14 is located on the side of the insulated door panel 100 facing the cabinet 900, which can hide at least part of the hinge portion 920 and the hinge groove 14, so that the outer surface of the insulated door panel 100 is relatively simple.

[0042] Please see Figure 8 In this embodiment, the hinge assembly 40 includes a pin 41 and a limiting member 42. The pin 41 includes a rotating shaft 411 and an abutment portion 412. The rotating shaft 411 passes through the hinge portion 920, and both ends of the rotating shaft 411 pass through the groove wall of the hinge groove 14 and extend into the receiving cavity 60. The abutment portion 412 is located in the receiving cavity 60 and connected to one end of the rotating shaft 411. The limiting member 42 is located in the receiving cavity 60 and detachably connected to the other end of the rotating shaft 411 to prevent the rotating shaft 411 from disengaging from the body of the hinge groove 14 and the hinge portion 920. In this embodiment, the rotating shaft 411 and the limiting member 42 can be detachably connected by a threaded structure. In other embodiments, the limiting member 42 can be a pin that can pass through the rotating shaft 411 radially to serve as a limiting element.

[0043] In this embodiment, the outer peripheral surface of the limiting member is a non-rotating surface. The body of the hinge groove 14 has a countersunk groove (not shown in the figure) on the side facing the receiving cavity 60. At least a portion of the structure of the limiting member 42 can be embedded in the countersunk groove and abut against the inner wall of the countersunk groove. At least a portion of the inner wall of the countersunk groove abuts against the outer peripheral surface of the limiting member 42 to restrict the rotation of the limiting member 42 and the rotating shaft 411 relative to the inner shell body 11, and to prevent the rotating shaft 411 from disengaging from the limiting member 42 during rotation. In this embodiment, the hinge assembly 40 also includes a protective sleeve 43. The protective sleeve ring 43 is disposed on the rotating shaft 411 and located between the rotating shaft 411 and the hinge portion 920 to prevent the rotating shaft 411 from causing wear to the hinge portion 920.

[0044] Please see Figure 1 and Figure 3 In this embodiment, with the insulated door panel 100 covering the storage space 910, the hinge groove 14 is located on the bottom side of the inner shell body 11, and multiple first fastening parts 12 are located above the hinge groove 14. Some of the first fastening parts 12 are located on the periphery of the inner shell body 11 to avoid the periphery structure of the insulation layer 70, and some of the first fastening parts 12 are located in the middle of the inner shell body 11. These first fastening parts 12 can be embedded in the avoidance through holes 71 provided on the insulation layer 70. Therefore, in this embodiment, the insulated door panel 100 can rotate relative to the cabinet 900 about the horizontal axis, and the hinge groove 14 is located on the bottom side of the insulated door panel 100 and is not easily noticed. When the insulated door panel 100 exposes the storage space 910, the hinge part 920 and the hinge groove 14 are covered by other structures of the insulated door panel 100, making the insulated door panel 100 more aesthetically pleasing.

[0045] Please see Figure 7 In this embodiment, the inner shell 10 further includes a stacking portion 13, which is connected to the inner shell body 11 and bent toward the outer shell body 21 relative to the inner shell body 11. When the inner shell 10 and the outer shell 20 are connected, at least a portion of the structure of the stacking portion 13 overlaps with the outer shell body 20. Specifically, please refer to... Figure 3In this embodiment, the outer shell body 23 includes a flat outer surface portion (not shown in the figure) and a locking portion 23. The locking portion 23 is connected to the side of the outer surface portion facing the inner shell body 11 and extends relative to the outer surface portion towards the inner shell body 11. When the inner shell 10 and the outer shell 20 are connected, the locking portion 23 is stacked on the side of the stacked portion 13 facing the receiving cavity 60. The fastening connector 30 passes through the stacked portion 13 and the locking portion 23 of the outer shell body 21 in sequence to fix the stacked portion 13 and the locking portion 23, and to fix the inner shell body 11 and the outer shell body 21, thereby restricting the movement of the first fastening portion 12 relative to the second fastening portion 22. In this embodiment, the fastening connector 30 can be a screw, which passes through the stacked portion 13 and is locked to the locking portion 23. In this embodiment, the locking portion 23 is a block structure for the fastening connector 30 to pass through or be embedded in. In other embodiments, the locking portion 23 can be a plate structure.

[0046] In this embodiment, the hinge groove 14 is located at the connection between the stacked portion 13 and the inner shell body 11. The opening of the hinge groove 14 is exposed on both the side of the inner shell body 11 away from the receiving cavity 60 and the side of the stacked portion 13 away from the receiving cavity 60, so that the openness of the hinge groove 14 is relatively large, which facilitates the rotation of the hinge portion 920 within the hinge groove 14. In this embodiment, the stacked portion 13 and the fastening connector 30 are located at the connection between the cabinet 900 and the insulation door panel 100. The fastening connector 30 and the stacked portion 13 are relatively concealed on the insulation door panel 100. In this embodiment, the stacked portion 13 is located on the bottom side of the inner shell body 11 and the insulation door panel 100, and is not easily discovered. When the insulation door panel 100 is opened, the stacked portion 13 and the fastening connector 30 are covered by other structures of the insulation door panel 100, and the outer surface of the insulation door panel 100 observed by the user does not have a connecting structure.

[0047] Please see Figure 3 In this embodiment, the outer shell 20 further includes a perimeter 24, which is connected to a portion of the periphery of the outer shell body 21 and extends toward the inner shell body 11 relative to the outer shell body 21. When the outer shell 20 is connected to the inner shell 10, the two ends of the overlapping portion 13 overlap with the two ends of the perimeter 24, and the perimeter 24 is arranged around a portion of the periphery of the inner shell body 11. In this embodiment, the perimeter 24 overlaps with the overlapping portion 13 to improve the sealing degree of the receiving cavity 60.

[0048] Please see Figure 2 and Figure 3In this embodiment, the outer shell 20 is provided with a handle groove 241, which is connected to the outer shell body 21. In this embodiment, the side of the perimeter 24 facing away from the receiving cavity 60 is recessed towards the receiving cavity 60 to define the handle groove 241, making the handle groove 241 relatively concealed. In this embodiment, the handle groove 241 and the hinge groove 14 mentioned above are located on opposite sides of the insulated door panel 100, so that the user can easily pull the insulated door panel 100 to rotate by the handle groove 241 with less effort. In this embodiment, the outer shell body 21 includes a thick material portion 211 and a thin material portion 212 connected to each other. The average thickness of the thick material portion 211 is greater than the average thickness of the thin material portion 212, and the thick material portion 211 is located between the handle groove 241 and the thin material portion 212. In this embodiment, the thick material portion 211 has greater strength and can withstand greater external forces. The thick material portion 211 is closer to the handle groove 241 than the thin material portion 212, which can prevent the outer shell body 21 from deforming under force.

[0049] In this embodiment, the inner shell body 11 has a mounting portion on the side opposite to the receiving cavity 60. The ice-making device 1000 also includes a functional module, and the mounting portion is used to install the functional module. This embodiment does not limit the structure of the mounting portion or the type of the functional module, and can be specifically set according to the actual situation. As an example, the mounting portion includes multiple mounting clips 151, and the functional module includes a storage basket. The storage basket has multiple mating clips, and the multiple mounting clips 151 correspond one-to-one with the multiple mating clips and are fastened together to detachably install the storage basket onto the heat-insulating door panel 100. As another example, the mounting portion includes multiple mounting grooves 152 formed on the inner shell body 11, and the functional module includes a guide plate. At least a portion of the structure of the guide plate can be embedded in the multiple mounting grooves 152 to connect the guide plate and the heat-insulating door panel 100.

[0050] In this embodiment, the insulated door panel 100 also includes multiple magnetic components 50, such as magnets. These magnetic components 50 are connected to the side of the inner shell body 11 facing the receiving cavity 60. In this embodiment, the cabinet body 900 is made of iron alloy and may include a stainless steel storage cabinet or an iron alloy storage cabinet. When the insulated door panel 100 covers the storage space 910, the multiple magnetic components 50 and the cabinet body 900 have a magnetic attraction effect, connecting the insulated door panel 100 and the cabinet body 900 to prevent the insulated door panel 100 from rotating automatically. In this embodiment, when the insulated door panel 100 covers the storage space 910, the multiple magnetic components 50 are sequentially and spaced apart around the periphery of the opening of the storage space 910, improving the sealing effect.

[0051] This embodiment provides an insulated door panel 100, which includes an outer shell 20 and an inner shell 10 that are fastened together. The inner shell 10 includes an inner shell body 11 and a first fastening portion 12. The outer shell 20 includes an outer shell body 21 and a second fastening portion 22. The outer shell body 21 and the inner shell body 11 together define a receiving cavity 60 of the insulated door panel 100. The first fastening portion 12 and the second fastening portion 22 are both located within the receiving cavity 60 and are fastened together within the receiving cavity 60 to detachably connect the outer shell body 21 and the inner shell body 11. A fastening connector 30 is connected between the outer shell body 21 and the inner shell body 11 to restrict the movement of the outer shell body 21 relative to the inner shell body 11, so as to prevent the first fastening portion 12 from separating from the second fastening portion 22.

[0052] In this embodiment, the first fastening part 12 and the second fastening part 22 are located within the receiving cavity 60 of the heat-insulating door panel 100, and the fastening structure has minimal impact on the aesthetics of the outer surface of the heat-insulating door panel 100. In this embodiment, the fastening structure can effectively connect the outer shell 20 and the inner shell 10. On the one hand, it can reduce the use of fastening connectors 30, avoid setting too many fastening connectors 30 on the heat-insulating door panel 100, and avoid exposing the structure of too many fastening connectors 30 on the outer surface of the heat-insulating door panel 100, making the outer surface of the heat-insulating door panel 100 simpler and more aesthetically pleasing. On the other hand, the fastening process of the fastening structure is relatively simple, greatly simplifying the steps of assembling the heat-insulating door panel 100 and improving assembly efficiency.
