Technical Field

[0001] The present invention relates to the field of refrigeration appliances, and in particular to a door assembly for refrigeration appliances. The present invention also relates to a corresponding refrigeration appliance. Background Art

[0002] In recent years, with the development of technology and the improvement of living standards, people have higher and higher requirements for refrigeration appliances, such as refrigerators or wine cabinets. On the one hand, people hope that the refrigeration appliances have a large storage capacity, and on the other hand, they hope that the size of the refrigeration appliances meets the space requirements of the home and can ensure the desired cooling effect. Summary of the invention

[0003] Therefore, an object of an embodiment of the present invention is to provide an improved door assembly for a refrigeration appliance, wherein the door assembly can effectively prevent the cooling capacity of the refrigeration appliance from leaking while increasing the storage capacity of the refrigeration appliance.

[0004] According to a first aspect of the present invention, a door assembly for a refrigeration appliance is provided, wherein the door assembly is configured to be suitable for opening or closing a cabinet of the refrigeration appliance, wherein the door assembly at least comprises:

[0005] - an inner door, the inner door being configured to be arranged at a front portion of the box body so as to be pivotable relative to the box body, wherein the inner door has a first door frame, the first door frame enclosing an inner door cavity;

[0006] - a first door seal, which is arranged on the rear side of the first door frame and is configured to achieve a sealed closure of the first door frame relative to the box body when the inner door is closed; and

[0007] - an outer door, the outer door being pivotally arranged at the front of the inner door relative to the inner door and being configured to open or close the inner door cavity, wherein the outer door has an insulating glass module, the insulating glass module comprising at least two layers of glass plates spaced apart from each other, wherein a sealing portion is provided between adjacent glass plates, and an insulating space is formed between the glass plates by the sealing portion,

[0008] The sealing portion has a first sealing section, and when viewed in a direction parallel to a main extension plane of the door assembly, the first sealing section is located on the outer side of the first door seal.

[0009] Compared with the prior art, the door assembly for a refrigeration appliance according to the present invention makes the sealing part of the insulating glass module of the outer door at least partially located on the outside of the first door seal of the inner door, so that the insulating space surrounded by the sealing part of the insulating glass module at least partially exceeds the refrigeration space in the refrigeration appliance in the projection plane perpendicular to the thickness direction. In this case, the insulating space exists between the refrigeration space and the external environment, and the heat transfer between the refrigeration space and the external environment can be hindered by the insulating space, and the sealing part of the insulating glass module is located outside the refrigeration space, which can effectively prevent the cold in the refrigeration space from leaking outward through the outer periphery of the sealing part, thereby improving the refrigeration effect of the refrigeration appliance. Further, because the insulating space of the insulating glass module hinders the heat transfer between the refrigeration space and the external environment and the cold in the refrigeration space cannot leak outward through the outer periphery of the sealing part, the temperature of the front side of the insulating glass module will not be affected by the cold in the refrigeration space and is basically maintained at the ambient temperature, so that the water vapor in the ambient air will not condense on the front side of the insulating glass module, thereby avoiding the condensation phenomenon on the front side of the insulating glass module.

[0010] According to an exemplary embodiment of the present application, in the projection plane of the door assembly perpendicular to the thickness direction, the projection of the first sealing section is spaced apart from the projection of the first door seal. In this case, there is an insulating space of the insulating glass module between the first sealing section of the sealing part and the first door seal, which can prevent the coldness of the refrigeration space from leaking outward through the sealing part as much as possible through the insulating space. However, it can also be considered that, in combination with the specific requirements of the manufacture and assembly of the door assembly, in the projection plane of the door assembly perpendicular to the thickness direction, the projection of the first sealing section is adjacent to the projection of the first door seal; and / or, in the projection plane of the door assembly perpendicular to the thickness direction, a part of the projection of the first sealing section overlaps with the projection of the first door seal and the rest is located on the outside of the first door seal.

[0011] According to an exemplary embodiment of the present application, the sealing portion extends along the outer edge of at least one glass plate of the insulating glass module, so that the sealing portion has an annular configuration surrounding the glass plate; and / or the sealing portion has a constant width over the entire longitudinal extension. This can achieve the largest possible insulation space of the insulating glass module and ensure uniform sealing and insulation performance of the sealing portion.

[0012] According to an exemplary embodiment of the present application, the first sealing section extends over the entire longitudinal extension of at least one side of the sealing portion. In particular, the first sealing section extends over the longitudinal extension of all sides of the sealing portion. This can optimize the heat insulation sealing effect of the door assembly relative to the cabinet to prevent the cold in the refrigeration space from leaking outward, thereby improving the refrigeration performance of the refrigeration appliance.

[0013] According to an exemplary embodiment of the present application, the sealing portion has a second sealing section, and in a projection plane perpendicular to the thickness direction of the door assembly, the projection of the second sealing section completely overlaps with the projection of the first door seal or is surrounded by the projection of the first door seal. This allows for a flexible configuration of the door assembly based on actual manufacturing and assembly requirements.

[0014] According to an exemplary embodiment of the present application, the door assembly is provided with a second hinge mechanism and / or a second grip portion for the outer door at a position adjacent to the second sealing section; and / or the sealing portion has the first sealing section and the second sealing section in at least one side. This facilitates the provision of functional components in the second sealing section without having to provide the entire insulating glass module or the rear side of the outer door, thereby achieving a relatively thin configuration of the door assembly.

[0015] According to an exemplary embodiment of the present application, the first door frame has a first assembly part for assembling the first door seal, the first assembly part is provided with at least one embedding recess, and the first door seal is provided with at least one embedding protrusion for embedding into the embedding recess. The first door seal can be installed firmly and seamlessly on the first door frame through the cooperation of the embedding recess of the first assembly part and the embedding protrusion of the first door seal, thereby preventing the first door seal from accidentally falling off or unexpected cold leakage.

[0016] According to an exemplary embodiment of the present application, the door assembly includes a second door seal, which is configured to achieve a sealed closure of the outer door relative to the first door frame when the outer door is closed. The second door seal can prevent cold energy from leaking outward through the gap between the outer door and the inner door.

[0017] According to an exemplary embodiment of the present application, the outer door has a second door frame, and the second door frame is configured to carry the insulating glass module, wherein the second door seal is assembled on the rear side of the second door frame. The second door frame can increase the assembly strength of the outer door or the insulating glass module. Here, in the projection plane of the door assembly perpendicular to the thickness direction, the projection of the second door seal is completely located inside the projection of the sealing portion, so that the second door seal is completely covered by the insulating space of the insulating glass module to prevent the cold from leaking outward along the edge of the second door seal.

[0018] According to an exemplary embodiment of the present application, the first door frame has a first foaming space, in which a heat-insulating foaming material is filled, and / or the second door frame has a second foaming space, in which a heat-insulating foaming material is filled, and in a projection plane perpendicular to the thickness direction of the door assembly, the sealing portion is located in the region of the second foaming space. The foaming material arranged in the foaming space further improves the heat insulation capacity of the door assembly and the cooling effect of the cooling device.

[0019] According to an exemplary embodiment of the present application, the first door frame has a first hinge assembly part for a first hinge mechanism of the inner door, the first hinge mechanism is configured to be suitable for being arranged between the inner door and the box body, and the first hinge assembly part is implemented as a hinge shaft or an axis hole for the hinge shaft; and / or, the door assembly has a second hinge mechanism for the outer door, the second hinge mechanism is arranged between the inner door and the outer door, and the second door frame has a second hinge assembly part for the second hinge mechanism, the second hinge assembly part is implemented as a hinge shaft or an axis hole for the hinge shaft. This can realize the pivotable arrangement of the inner door relative to the box body and the pivotable arrangement of the outer door relative to the inner door. In addition, it can also be considered that the door assembly has a second hinge mechanism for the outer door, the second hinge mechanism is arranged between the inner door and the outer door, wherein the second hinge assembly part of the second hinge mechanism is arranged on the rear side of the insulating glass module of the outer door and is implemented as a hinge shaft or an axis hole for the hinge shaft. In this case, the second hinge mechanism for the outer door can be directly arranged on the rear side of the insulating glass module of the outer door without providing a second door frame for the outer door.

[0020] According to an exemplary embodiment of the present application, the first door frame has a first grip portion that is concave inwardly along a direction parallel to a main extension plane of the door assembly.

[0021] According to an exemplary embodiment of the present application, the frontmost first glass plate of the insulating glass module has a protruding edge relative to the rear second glass plate, and the protruding edge is fixedly placed on the bearing flange of the second door frame, wherein the rear glass plate of the insulating glass module is placed in the accommodation space surrounded by the bearing flange. In this way, part of the glass plate of the insulating glass module can be sunk into the accommodation space of the second door frame, thereby significantly reducing the assembly thickness of the entire door assembly.

[0022] According to an exemplary embodiment of the present application, the second door frame has a second assembly portion for assembling the second door seal, the second assembly portion surrounds the inner door cavity, and the second assembly portion particularly supports the thermal insulation glass module. This can significantly increase the stability of the thermal insulation glass module while achieving reliable assembly of the second door seal.

[0023] According to an exemplary embodiment of the present application, the thermal insulation glass module is implemented as a vacuum glass module or a hollow glass module, and in the hollow glass module, the thermal insulation space is filled with an inert gas.

[0024] According to an exemplary embodiment of the present application, a front door panel is spaced apart in front of the heat-insulating glass module.

[0025] According to an exemplary embodiment of the present application, the heat-insulating glass module comprises a first glass plate and a second glass plate, wherein the first glass plate is located in front of the second glass plate, wherein the second glass plate has an irregular shape and has a yield structure at a position corresponding to the second hinge mechanism and / or the second grip portion of the outer door. This can significantly reduce the thickness and weight of the door assembly while maintaining good heat-insulating performance.

[0026] According to a second aspect of the present invention, a refrigeration appliance is provided. The refrigeration assembly comprises a cabinet and at least one door assembly according to the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Figure 1A perspective view of a door assembly 100 for a refrigeration appliance according to an exemplary embodiment of the present invention is shown. Figure 2 An exploded view of the door assembly 100 is shown. Here, the refrigeration appliance can be configured as a refrigerator and includes a box body and a door assembly 100, wherein the door assembly is configured to open or close the box body to jointly define a refrigeration space of the refrigeration appliance. However, it is also conceivable that the refrigeration appliance is a freezer, a wine cabinet, or other appliances that are considered meaningful by those skilled in the art.

[0045] like Figure 2 As shown, the door assembly 100 includes an inner door 10 and an outer door 20, wherein the inner door 10 can be pivotally arranged at the front of the box body relative to the box body of the refrigeration appliance, and the outer door 20 can be pivotally arranged at the front of the inner door 10 relative to the inner door 10, wherein the inner door 10 has a first door frame 11, the first door frame surrounds an inner door cavity 12, the inner door cavity can directly lead to the internal space of the box body, and can also form a accommodating chamber separated from the internal space of the box body, and the outer door 20 is configured to open or close the inner door cavity 12. When the user uses the refrigeration appliance, on the one hand, the outer door 20 can be opened to contact the inner door cavity 12 of the inner door 10 or to contact the internal space of the box body through the inner door cavity 12, and on the other hand, the inner door 10 can also be opened to directly contact the internal space of the box body.

[0046] like Figure 2 As shown, the door assembly 100 includes a first door seal 30, which is arranged on the rear side of the first door frame 11 of the inner door 10. When the inner door 10 is closed, the first door seal is arranged between the first door frame 11 and the cabinet of the refrigeration appliance and is configured to achieve a sealed closure of the first door frame 11 relative to the cabinet to prevent the coldness of the refrigeration space of the cabinet from leaking through the gap between the inner door 10 and the cabinet.

[0047] like Figure 2 As shown, the outer door 20 of the door assembly 100 has an insulating glass module 21, through which the inner door cavity 12 of the inner door 10 can be sealed in an insulating manner, thereby preventing heat transfer between the external environment and the inner door cavity 12. Here, the insulating glass module 21 includes at least two layers of glass plates 211 and 212 spaced apart from each other, wherein a sealing portion 213 is provided between adjacent glass plates, and an insulating space 214 is formed between adjacent glass plates by the sealing portion, see Figure 3 and Figure 4Here, the insulating glass module 21 can be constructed as a vacuum glass module, so that the insulating space 214 is in a nearly vacuum state, thereby minimizing the heat dissipated by heat conduction, heat convection and heat radiation and improving the insulation effect of the insulating glass module 21 as much as possible. However, it is also conceivable that the insulating glass module 21 is constructed as a hollow glass module, and the insulating space 214 of the hollow glass module is filled with an inert gas, which can also improve the insulation effect of the insulating glass module 21.

[0048] Figure 3 1 is a schematic view showing an insulating glass module 21 of a door assembly 100 according to an exemplary embodiment of the present invention, Figure 4 Shows Figure 3 sectional view of .

[0049] like Figure 3 and Figure 4 As shown, the heat-insulating glass module 21 exemplarily includes a first glass plate 211 and a second glass plate 212, wherein, viewed along the depth direction of the refrigeration appliance, the first glass plate 211 is located in front of the second glass plate 212 and is arranged spaced apart from the second glass plate 212, wherein a sealing portion 213 is provided between the first glass plate 211 and the second glass plate 212, and the sealing portion and the two glass plates form a heat-insulating space 214. Of course, it is also conceivable that the heat-insulating glass module 21 includes more, for example, three glass plates, and sealing portions are respectively arranged between adjacent glass plates to form a heat-insulating space, so as to further improve the heat-insulating performance of the heat-insulating glass module 21, but the thickness of such a heat-insulating glass module is relatively large.

[0050] For example, Figure 3 As shown, the sealing portion 213 runs along the outer edge of the second glass plate 212 of the insulating glass module 21, so that the sealing portion 213 has an annular configuration surrounding the second glass plate 212, which can achieve the largest possible area of ​​the insulating space 214 surrounded by the sealing portion 213. Here, when the first glass plate 211 and the second glass plate 212 have the same shape, the sealing portion 213 can run along the outermost edges of the first glass plate 211 and the second glass plate 212.

[0051] For example, Figure 3 As shown, the seal 213 has a constant width over the entire longitudinal extension, thereby simplifying the arrangement of the seal 213 in the insulating glass module 21 and achieving uniform sealing performance of the seal 213 .

[0052] Figure 5A projection view of a door assembly 100 for a refrigeration appliance according to an exemplary embodiment of the present invention is shown, the projection view is oriented perpendicular to the thickness direction of the door assembly 100 , and the insulation glass module 21 and the first door seal 30 are mainly shown in the projection view.

[0053] like Figure 5 As shown, the sealing portion 213 is constructed in an annular shape along the outer edge of the second glass plate 212 and has a first sealing section 1. When viewed in a direction parallel to the main extension plane of the door assembly 100, the first sealing section 1 is located on the outside of the first door seal 30, which makes the sealing portion 213 at least partially arranged on the outside of the first door seal 30 at least on the extension scale of the first sealing section 1, thereby effectively preventing the cold in the refrigeration space from leaking outward through the outer periphery of the sealing portion and avoiding condensation on the front side of the insulating glass module 21.

[0054] For example, Figure 5 As shown, in the projection plane of the door assembly 100 perpendicular to the thickness direction, for example, the projection of the first sealing section 1 on the upper side of the sealing portion 213 is located outside the first door seal 30 and is separated from the projection of the first door seal 30, and there is a heat-insulating space between the first sealing section 1 and the first door seal 30, through which the heat transfer between the refrigeration space and the first sealing section 1 can be reduced as much as possible, thereby improving the refrigeration effect of the refrigeration device. In addition, for example, a part of the projection of the first sealing section 1 on the lower side of the sealing portion 213 overlaps with the projection of the first door seal 30 and the rest is located outside the first door seal 30. Of course, it can also be considered that in the projection plane of the door assembly 100 perpendicular to the thickness direction, the projection of the first sealing section 1 is adjacent to the projection of the first door seal 30. Here, the relative positional relationship between the first sealing section 1 and the first door seal 30 can be determined according to the manufacturing and assembly requirements of the insulating glass module 21.

[0055] For example, Figure 5 As shown, the first sealing section 1 extends over the entire longitudinal extension of at least one side of the sealing portion 213, which allows the sealing portion 213 to be easily arranged in the insulating glass module 21 and can improve the thermal insulation performance as much as possible at the corresponding side. In particular, the first sealing section 1 extends over the entire peripheral extension of the sealing portion 213, which can achieve uniform and optimized thermal insulation performance of the door assembly 100 on the peripheral side.

[0056] For example, Figure 5As shown, the sealing portion 213 may also have a second sealing section 2, and in the projection plane of the door assembly 100 perpendicular to the thickness direction, the projection of the second sealing section 2 completely overlaps with the projection of the first door seal 30 or is surrounded by the projection of the first door seal 30. In the framework of the present invention, "the projection of the second sealing section 2 is surrounded by the projection of the first door seal 30" means that the projection of the second sealing section 2 is partially or completely located inside the projection of the first door seal 30. Here, the sealing portion 213 is composed of the first sealing section 1 and the second sealing section 2, wherein the first sealing section 1 and the second sealing section 2 can be arranged successively in at least one side of the sealing portion 213. Here, the setting of the second sealing section 2 depends on the actual manufacturing and assembly requirements of the door assembly 100 and allows the realization of a specific functional area of ​​the door assembly 100, such as a grip or hinge mechanism for the outer door 20.

[0057] Figure 6 A cross-sectional view of a door assembly 100 for a refrigeration appliance according to an exemplary embodiment of the present invention is shown.

[0058] like Figure 6 As shown, the first door frame 11 of the inner door 10 encloses an inner door cavity 12, which can lead to the inner space of the cabinet of the refrigeration appliance or be separated from the inner space, wherein the first door seal 30 mounted on the rear side of the first door frame 11 is located on the inner side of the first sealing section 1 of the sealing portion 213 in a direction parallel to the main extension plane of the door assembly 100 to cut off the cold leakage path. The first door frame 11 has a first assembly portion 14 for mounting the first door seal 30, the first assembly portion is provided with at least one, especially a plurality of engaging recesses 141, and the first door seal 30 is provided with an engaging protrusion 31 for embedding into the engaging recess 141. When the first door seal 30 is installed in the first assembly portion 14, the engaging protrusion 31 of the first door seal 30 is embedded in the engaging recess 141, thereby achieving a firm installation of the first door seal 30 on the rear side of the first door frame 11. Here, the first door seal 30 is annularly configured around the inner door chamber 12 to completely prevent cold leakage between the inner door 10 and the housing in the circumferential direction.

[0059] like Figure 6 As shown, the first door frame 11 of the inner door 10 has a first foaming space 15, in which a heat-insulating foaming material is filled, which can reduce the thermal conductivity of the first door frame 11 and improve the heat-insulating performance of the inner door 10. Here, the first foaming space 15 particularly covers the area of ​​the first door seal 30 in the projection plane, thereby eliminating the cold leakage path of the inner door 10.

[0060] like Figure 6As shown, the outer door 20 of the door assembly 100 includes a second door frame 22, and the second door frame is constructed to support an insulating glass module 21, wherein a first glass plate 211 at the front of the insulating glass module 21 has a protruding edge 215 relative to a second glass plate 212 at the rear, and the protruding edge is fixed on a supporting flange 25 of the second door frame 22, wherein the second glass plate 212 at the rear of the insulating glass module 21 is placed in an accommodating space 26 surrounded by the supporting flange 25, which can increase the strength of the outer door 20 and effectively reduce the thickness of the outer door 20.

[0061] like Figure 6 As shown, the door assembly 100 also includes a second door seal, which is configured to achieve a sealed closure of the outer door 20 relative to the first door frame 11 of the inner door 10 when the outer door 20 is closed, thereby preventing the cold in the inner door cavity 12 of the inner door 10 from leaking outward through the gap between the outer door 20 and the inner door 10, so as to improve the refrigeration effect of the refrigeration appliance. Here, the second door seal is particularly mounted on the rear side of the second door frame 22, and the second door frame has a second assembly portion 24 for assembling the second door seal, and the second assembly portion surrounds the inner door cavity 12, which allows the second door seal to seal the inner door cavity 12 relative to the external environment in the circumferential direction. In particular, the bottom of the second assembly portion 24 can support the insulating glass module 21, which can provide more support points for the insulating glass module 21 and improve the assembly stability of the insulating glass module 21. Here, in the projection plane of the door assembly 100 perpendicular to the thickness direction, the projection of the second door seal or the second assembly part 24 is completely located on the inner side of the projection of the sealing part 213, so that the second door seal is covered by the insulating space 213 of the insulating glass module 21, thereby effectively preventing the cold from leaking to the external environment through the outer edge of the sealing part 213.

[0062] like Figure 6 As shown, the second door frame 22 of the outer door 20 has a second foaming space 27, in which the second foaming space is filled with a heat-insulating foaming material. In the projection plane of the door assembly 100 perpendicular to the thickness direction, the sealing portion 213 is in the area of ​​the second foaming space 27 to improve the heat-insulating performance of the outer door 20.

[0063] Figure 7 A perspective view of an inner door 10 of a door assembly 100 according to an exemplary embodiment of the present invention is shown.

[0064] like Figure 2 and Figure 7As shown, a first hinge mechanism 13 is arranged between the inner door 10 and the box body, and the inner door 10 can be pivoted relative to the box body through the first hinge mechanism, wherein the first door frame 11 has a first hinge assembly part 131 for the first hinge mechanism 13, and the first hinge assembly part is implemented as a hinge shaft or an axial hole for the hinge shaft, and a first hinge corresponding part cooperating with the first hinge assembly part 131 is provided on the box body, and the first hinge corresponding part is correspondingly implemented as an axial hole or a hinge shaft.

[0065] like Figure 7 As shown, the inner door 10 has a first grip portion 16 , which allows a user to easily open and close the inner door 10 , wherein the first grip portion 16 is particularly configured as the first door frame 11 having an inner recess along a direction parallel to the main extension plane of the door assembly 100 .

[0066] Figure 8 A perspective view of an outer door 20 of a door assembly 100 according to an exemplary embodiment of the present invention is shown.

[0067] like Figure 2 and Figure 8 As shown, the door assembly 100 has a second hinge mechanism 23 arranged between the inner door 10 and the outer door 20, and the outer door 20 can be pivoted relative to the inner door 10 by the second hinge mechanism, wherein the second door frame 22 has a second hinge assembly part 231 for the second hinge mechanism 23, and the second hinge assembly part is implemented as a hinge shaft or an axis hole for the hinge shaft, and a second hinge counterpart that cooperates with the second hinge assembly part is provided on the first door frame 11 of the inner door 10, and the second hinge counterpart is correspondingly implemented as an axis hole or a hinge shaft. In particular, the second hinge counterpart and the first hinge assembly part 131 are integrally constructed. However, it is also conceivable that the second hinge assembly part 231 of the second hinge mechanism 23 is arranged on the rear side of the insulating glass module 21 of the outer door 20, especially the second glass plate 212, which can eliminate the second door frame 22 for the outer door 20 and make the thickness of the outer door 20 as small as possible.

[0068] like Figure 8 As shown, the outer door 20 has a second gripping portion 28, which can be constructed by an inner recess of the second door frame 22 in a direction parallel to the main extension plane.
