[0039] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0040] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0041] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0042] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0043] like Figures 1 to 5 As shown, this utility model proposes a refrigeration storage device 100, including a housing 10, a door 20, a hinge assembly 30, a wiring harness assembly 40, and a liquid flow pipe 50. The housing 10 has an internal cavity 11 with an opening 12. The door 20 has a first slide rail 21, a second slide rail 22, a first connecting hole 23, and a second connecting hole 24. The hinge assembly 30 is mounted on the housing 10 and includes a first rotating shaft 31 and a second rotating shaft 32. The first rotating shaft 31 is slidably connected to the first slide rail 21, and the second rotating shaft 32 is slidably connected to the second slide rail 22. The door 20 can open or close the opening 12 during the sliding of the first rotating shaft 31 and the second rotating shaft 32. The wiring harness assembly 40 is connected to the housing 10 and passes through the first connecting hole 23. The liquid flow pipe 50 is connected to the housing 10 and passes through the second connecting hole 24.

[0044] As can be seen, the refrigeration storage device 100 proposed in this utility model is extracted from the pivot of the hinge assembly 30 through the wiring harness assembly 40 and the liquid flow pipeline 50. The first connection hole 23 and the second connection hole 24 are separately provided on the door body 20 for inserting the wiring harness assembly 40 and the liquid flow pipeline 50, so that the diameter of the first pivot 31 and the second pivot 32 of the hinge assembly 30 can be reduced, thereby reducing the thickness of the door body 20, improving the overall aesthetics and reducing the weight and cost of the whole machine.

[0045] For example, the refrigeration storage device 100 can be a refrigerator, freezer, or cold storage display case, etc. The main body of the refrigeration storage device 100 is a cabinet 10, and the interior of the cabinet 10 defines a receiving cavity 11. The walls of the cabinet 10 are filled with foam material for insulation. The refrigeration storage device 100 is also equipped with a refrigeration system, which creates a low-temperature environment in the receiving cavity 11 to store food. The front or top side of the refrigeration storage device 100, that is, the side of the refrigeration storage device 100 facing the user, forms an opening 12 that communicates with the receiving cavity 11. The edge of the door 20 can be pivotally connected to the cabinet 10 through a hinge assembly 30, so that the door 20 can rotate at the opening 12 to open or close the opening 12. The door 20 is roughly rectangular plate structure. The hinge assembly 30 includes a connecting plate 33, a first pivot 31, and a second pivot 32. The connecting plate 33 is mounted on the housing 10 and can be located on the top or bottom side of the housing 10, extending beyond the housing 10 along the depth direction of the receiving cavity 11. The first pivot 31 and the second pivot 32 are located on the portion of the connecting plate 33 that extends beyond the housing 10. To cooperate with the hinge assembly 30, a first slide rail 21 and a second slide rail 22 can be provided on the top or bottom side of the door 20. The first slide rail 21 and the second slide rail 22 can be arc-shaped, with the center of the arc closer to the side of the door 20 away from the receiving cavity 11 in the depth direction. The arc is also located closer to the side of the door 20 in the width direction of the housing 10, i.e., the arc is located as close as possible to the corner of the door 20, so that the door 20 does not extend beyond the housing 10 in the width direction during rotation. The first slide rail 21 can be located on the outer periphery of the second slide rail 22. The first rotating shaft 31 and the second rotating shaft 32 are inserted into the first slide rail 21 and the second slide rail 22, and are restricted from detaching by the first slide rail 21 and the second slide rail 22. To facilitate the installation of the wiring harness assembly 40, a first connecting hole 23 can be opened on the door body 20. The wiring harness assembly 40 is passed through the first connecting hole 23 and then embedded in the door body 20, allowing the wiring harness assembly 40 from the housing 10 to extend to other locations via the door body 20. Specifically, this can be used to connect the control panel of the door body 20 to the electrical device on the housing 10, or to connect the electrical device on the door body 20 to the electrical device on the housing 10 via the wiring harness assembly 40. To facilitate the flow of liquids, such as the water supply pipe of an ice maker, a second connecting hole 24 can be opened on the door body 20. The liquid flow pipe 50 is passed through the second connecting hole 24 and then embedded in the door body 20, allowing the liquid flow pipe 50 to extend from the housing 10 to other locations via the door body 20. In some scenarios where the ice maker and water tank are respectively located at the upper and lower ends of the refrigeration storage device 100, the liquid flow pipeline 50 of this application can be used to connect the ice maker and the water tank.

[0046] like Figures 1 to 2As shown, in some embodiments of this utility model, along the height direction of the box 10, the hinge assembly 30 is connected to the top of the box 10 and the top of the door 20 respectively, and the axial direction of the first connecting hole 23, the axial direction of the second connecting hole 24, the axial direction of the first rotating shaft 31 and the axial direction of the second rotating shaft 32 are all parallel to the height direction of the box 10.

[0047] As can be seen, by connecting the top of the housing 10 and the door 20 with the hinge assembly 30, and with the axes of the first connecting hole 23, the second connecting hole 24, the first rotating shaft 31 and the second rotating shaft 32 all parallel to the vertical direction, the door 20 can be rotated relative to the housing 10 to open or close the opening 12. At the same time, the liquid flow pipe 50 and the wiring harness assembly 40 from the top of the housing 10 can extend into the door 20 and connect to the water or electricity device installed on the door 20, or to the water or electricity device at the bottom of the housing 10.

[0048] For example, the hinge connecting plate 33 can be connected to the top of the housing 10 via bolts or a snap-fit ​​structure. The top of the housing 10 can be a position near the top of the housing 10, but not necessarily the very top. Similarly, for aesthetic reasons, the first connecting hole 23, the second connecting hole 24, the first pivot 31, and the second pivot 32 are also arranged near the top of the door 20, rather than at the very top, so that the hinge, slide rail, and hole structure can be covered and hidden by external structural components, making the overall exterior surface of the machine more concise. The first connecting hole 23 and the second connecting hole 24 can be formed by punching holes in the structural components of the door 20, the first slide rail 21 and the second slide rail 22 can be integrally formed by the structural components of the door 20, and the first pivot 31 and the second pivot 32 can be vertically welded to the connecting plate 33 by welding, resulting in higher overall structural strength.

[0049] like Figures 3 to 5 As shown, in some embodiments of this utility model, the hinge assembly 30 further includes a connecting plate 33. The connecting plate 33 includes a first part 331 and a second part 332 that are connected to each other. The first part 331 is connected to the housing 10, and the second part 332 is located outside the housing 10 in the depth direction of the receiving cavity 11. The first rotating shaft 31 and the second rotating shaft 32 are both perpendicularly connected to the first part 331. The first rotating shaft 31, the second rotating shaft 32 and the housing 10 are all located on the same side of the connecting plate 33 along the height direction of the housing 10.

[0050] As can be seen, by setting the first rotating shaft 31 and the second rotating shaft 32 on the connecting plate 33, the door 20 is pivotally connected to the box 10. The second part 332 of the connecting plate 33 is located outside the box 10, so that the second part 332 can be set between the first rotating shaft 31 and the second rotating shaft 32 with a distance between them. This allows the rotation axis of the door 20 to have a certain distance from the box 10 in the depth direction of the receiving cavity 11. This distance matches the thickness of the door 20, so that the door 20 does not exceed the box during rotation, improving the overall compactness and user experience.

[0051] For example, the first part 331 of the connecting plate 33 is connected to the housing 10, and its structure can be a generally rectangular flat plate structure. The second part 332 protrudes from the housing 10 in the depth direction of the receiving cavity 11, and its structure can be L-shaped or J-shaped, so that the second part 332 has a certain bending resistance. To enhance the strength of the connecting plate 33, multiple reinforcing ribs extending along the depth direction of the receiving cavity 11 can be formed on the surface of the connecting plate 33. The first rotating shaft 31 and the second rotating shaft 32 can be set at the end of the second part 332 opposite to the receiving cavity 11 in the depth direction of the receiving cavity 11.

[0052] like Figures 3 to 5 As shown, in some embodiments of this utility model, the first slide rail 21 and the second slide rail 22 are arc-shaped and arranged around the axis of the second connecting hole 24. Along the depth direction of the receiving cavity 11, the first slide rail 21 is located between the second connecting hole 24 and the box 10, and the second slide rail 22 is located between the first slide rail 21 and the second connecting hole 24.

[0053] As can be seen, by extending the first slide rail 21 and the second slide rail 22 in an arc around the axis of the second connecting hole 24, the first slide rail 21, the second slide rail 22 and the second connecting hole 24 can be compactly arranged at the corner of the door body 20, thereby making the rotation axis of the door body 20 as close as possible to the corner of the door body 20 away from the box body 10, so that when the door body 20 rotates, the distance between the rotation axis of the door body 20 and the box body 10 is sufficient to accommodate the thickness of the door body 20, so that the door body 20 does not exceed the box when rotating.

[0054] For example, the second connecting hole 24 can be arranged at the corner of the door body 20 on the side opposite to the receiving cavity 11. The first slide rail 21 extends in a C-shape around the axial direction of the second connecting hole 24, and the second slide rail 22 extends in a C-shape and is arranged between the first slide rail 21 and the second connecting hole 24. The distance between the first slide rail 21 and the second slide rail 22, and the distance between the second slide rail 22 and the second connecting hole 24, are set to be as small as possible while ensuring structural strength. This arrangement allows the liquid flow pipe 50, when inserted into the second connecting hole 24, to be located on the rotation axis of the door body 20 and rotate with the door body 20. The torsional force received by the liquid flow pipe 50 when the door body 20 rotates is small, improving the durability of the liquid flow pipe 50. For this purpose, the liquid flow pipe 50 can be partially inserted into the second connecting hole 24 and clearance-fitted with the second connecting hole 24. Alternatively, it can be inserted into the opening of the second connecting hole 24 and can rotate relative to the second connecting hole 24.

[0055] like Figures 3 to 5 As shown, in some embodiments of this utility model, the door body 20 includes an end cap 25 and a door body 26. The end cap 25 is installed at the top of the door body 26 along the height direction of the box 10. The end cap 25 has a connecting groove 27, and the connecting groove 27 has a slot 271 facing the box 10. The second part 332 passes through the slot 271 and is inserted into the connecting groove 27. The first slide rail 21, the second slide rail 22, the first connecting hole 23 and the second connecting hole 24 are all provided on the bottom side of the connecting groove 27 along the height direction of the box 10. The first connecting hole 23 and the second connecting hole 24 are both connected to the side of the end cap 25 facing the door body 26 and are connected to the interior of the door body 26.

[0056] As can be seen, in order to improve the overall aesthetics of the machine, an end cap 25 can be set at the top of the door body 20. A connecting groove 27 is formed between the end cap 25 and the door body 26. The connecting groove 27 can accommodate the complex mechanism of connecting the hinge assembly 30 to the door body 20, as well as the slide rails and openings on the door body 20, making the outer surface of the machine more concise and beautiful.

[0057] For example, the end cap 25 can be an elongated structure, and the door body 26 is a rectangular plate structure. The interior of the door body 26 can be filled with insulation material. The end cap 25 can close the top opening 12 of the door body 26. An elongated connecting groove 27 can be opened on the side of the end cap 25 facing the housing 10. The connecting groove 27 is located at one end of the end cap 25 along the width direction of the door body 20. The shape of the connecting groove 27 matches the connecting plate 33, and the relative position change of the connecting plate 33 is taken into account when the door body 20 rotates. The side of the connecting groove 27 facing the housing 10 forms a slot 271, and the side of the connecting groove 27 facing the door body 26 also forms an opening 12 to facilitate the extension of the first rotating shaft 31, the second rotating shaft 32, the liquid flow pipeline 50, and the wiring harness assembly 40 into the interior of the door body 26.

[0058] like Figures 3 to 5 As shown, in some embodiments of this utility model, the ratio of the diameter of the larger of the first rotating shaft 31 and the second rotating shaft 32 to the thickness of the door body 20 (the length of the door body 20 along the depth direction of the receiving cavity) is between 0.1 and 0.2.

[0059] It can be seen that by limiting the ratio of the diameter of the first pivot 31 and the second pivot 32 to the thickness of the door body 20, the size ratio of the first pivot 31, the second pivot 32 and the door body 20 is coordinated, and the thickness of the door body 20 can decrease as the diameter of the first pivot 31 and the second pivot 32 decreases.

[0060] For example, the diameters of the first rotating shaft 31 and the second rotating shaft 32 can be the same. For instance, the diameters of the first rotating shaft 31 and the second rotating shaft 32 can be set to about 6mm. In this case, the thickness of the door body 20 can be set to 50mm to 60mm. The door body 20 is thinner, and the overall structure is more compact and aesthetically pleasing.

[0061] In some embodiments of this utility model, the portion of the wire harness assembly 40 located between the housing 10 and the door 20 is bendable;

[0062] And / or, the portion of the liquid communication pipe located in the second connection hole 24 is clearance-fitted with the second connection hole 24.

[0063] As can be seen, by designing the portion of the wiring harness assembly 40 located between the housing 10 and the door 20 to be flexible, the wiring harness assembly 40 is easily bent during the rotation of the door 20, reducing the likelihood of breakage due to external forces. Furthermore, the liquid connecting pipe is designed with a clearance fit between itself and the second connecting hole 24, ensuring that the liquid connecting pipe does not rotate with the door 20 during rotation, thus avoiding rotation driven by external forces and further reducing the likelihood of breakage.

[0064] For example, a flexible material such as a hose can be used as the portion of the wiring harness assembly 40 located between the housing 10 and the door 20. Furthermore, the diameter of the portion of the liquid communication pipe inserted into the second connection hole 24 is set to be smaller than the diameter of the second connection hole 24, allowing for a clearance fit, and the liquid communication pipe can rotate relative to the second connection hole 24.

[0065] like Figures 3 to 5 As shown, in some embodiments of this utility model, the wire harness assembly 40 includes a first wire harness 41, a terminal block 43, and a second wire harness 42 connected in sequence. The first wire harness 41 is installed in the housing 10, and the second wire harness 42 passes through the second connection hole 24. The first wire harness 41 and the second wire harness 42 are detachably connected through the terminal block 43.

[0066] As can be seen, the first wire harness 41 and the second wire harness 42 are connected by the terminal block 43, which facilitates the disassembly and assembly of the wire harness assembly 40. Furthermore, the wire harness assembly 40 can be disconnected through the terminal block 43 when the door body 20 is disassembled and installed.

[0067] For example, one end of the first wiring harness 41 can be plugged into a hole on the housing 10. The first wiring harness 41 passes through the interior of the housing 10 and is electrically connected to the electrical device inside the housing 10. The terminal block 43 can be a conventional plug-in terminal block 43. One end of the second wiring harness 42 is detachably connected to the end of the first wiring harness 41 away from the housing 10 via the terminal block 43. The other end of the second wiring harness 42 is plugged into the first connection hole 23 and extends to the electrical device on the door 20, or is guided through the door 20 to be electrically connected to other electrical devices.

[0068] In some embodiments of this utility model, the refrigeration storage device 100 further includes an ice-making device (not shown in the figure) and a water tank (not shown in the figure). The ice-making device is disposed in the receiving cavity 11 or on the door 20, and the water tank is disposed in the box 10. The water tank is connected to the ice-making device through a liquid communication pipe.

[0069] As can be seen, the ice-making device and the water tank are connected by a liquid connecting pipe through the door body 20. Since the liquid connecting pipe does not pass through the hinge assembly 30, the shaft diameter of the hinge assembly 30 is smaller, and the door body 20 can also be set with a smaller thickness.

[0070] For example, the ice-making device can evaporate ice and condense ice through a heat exchanger. The ice-making device can be set inside the door 20 or inside the receiving cavity 11. The water tank is generally set at the bottom of the box 10. Specifically, the water tank at the bottom can be connected to the ice-making device at the top through a liquid connecting pipe, and the water in the water tank can be supplied to the ice-making device through the liquid connecting pipe by a water pump to make ice.

[0071] In some embodiments of this utility model, the refrigeration storage device 100 further includes an electrical device (not shown in the figure), which is installed in the housing 10, and the wiring harness assembly 40 is electrically connected to the electrical device.

[0072] As can be seen, electrical devices or controllers are generally installed on the door body 20 or inside the housing 10. Specifically, the controller can be electrically connected to the electrical device through the wiring harness assembly 40. The wiring harness assembly 40 passes through the door body 20 and is not connected to the hinge assembly 30, thereby reducing the size of the hinge assembly 30 and the thickness of the door body 20. The door body 20 can also fix and limit the wiring harness assembly 40, improving the reliability of the wiring harness assembly 40 installation.
