Description

Domestic refrigeration appliance

Technical Field

The application relates to the field of household appliances, in particular to a household refrigeration appliance.

Background

Domestic refrigeration appliances are now in the path of thousands of households, such as refrigerators, wine cabinets and the like. For convenience of use, domestic refrigeration appliances are known which employ a double door design. For example, a door of a refrigerator may be designed to include an outer door and an inner door. The inner door can be provided with an inner door cavity, so that a user can take and place objects in the refrigerator only by opening the outer door, the use by the user is facilitated, and the loss of the refrigerating capacity of the refrigerator when the door is opened is reduced.

The outer door and the inner door are sealed through a sealing piece. In order to achieve a good sealing effect, the flatness requirements of the surfaces clamped on both sides of the seal are high. This makes the outer and inner doors difficult to manufacture. In addition, the existing outer and inner doors are to be improved in terms of appearance.

Disclosure of Invention

It is an object of embodiments of the present application to provide an improved domestic refrigeration appliance in order to improve the sealing effect and reduce the manufacturing difficulties.

According to a first aspect of the present application, embodiments of the present application provide a domestic refrigeration appliance comprising a cabinet having a storage compartment and a door assembly for closing the storage compartment. The door assembly includes: an inner door movably connected to the cabinet and formed with an inner door cavity having an inner door opening; an outer door movably disposed at an opposite side of the inner door from the cabinet to open and close the inner door opening, wherein a first surface of the inner door surrounding the inner door opening is opposite to a second surface of the outer door surrounding the inner door opening in a case where the outer door is in a closed position; and a seal sandwiched between the first surface and the second surface with the outer door in the closed position. At least one of the first surface and the second surface includes a plurality of face regions, any two adjacent face regions of the plurality of face regions being different faces from each other. One of the plurality of face areas is formed as a seal mounting face on which the seal is mounted; or one of the plurality of surface areas is formed as a seal abutment surface on which the seal abuts with the outer door in the closed position.

By splitting the first surface and/or the second surface into a plurality of surface regions including the seal attachment surface or the seal abutment surface, it is possible to contribute to improving the flatness of the seal attachment surface or the seal abutment surface so as to ensure a good sealing effect of the seal. Thus, the seal attachment surface or the seal contact surface having a high flatness can be manufactured in a simple manner, and the difficulty in manufacturing can be reduced. This splitting also enables the first and/or second surfaces, which are otherwise visually wide, to be formed into a relatively narrow and stereoscopic visual effect, making the inner and/or outer door more attractive. In addition, the first and/or second surfaces that are subject to splitting may have greater structural strength than if they were integrally formed as a single plane.

According to an alternative embodiment of the present application, the seal mounting face or the seal abutment face is located adjacent an inner side of the interior door cavity compared to other face regions of the plurality of face regions other than the seal mounting face or the seal abutment face. This helps to improve the sealing and insulating effect of the seal.

According to an alternative embodiment of the present application, the main plane parallel to the door assembly is measured in an inside-out direction with respect to the inner door cavity: each of the other face regions has a size equal to that of the seal mounting face or the seal abutment face. Thereby, the first surface and/or the second surface can be split substantially evenly, so that the first surface and/or the second surface has a neater and more square appearance.

According to an alternative embodiment of the present application, the main plane parallel to the door assembly is measured in an inside-out direction with respect to the inner door cavity: each of the other face regions has a size larger than that of the seal mounting face or the seal abutment face. This is advantageous in ensuring that the seal mounting face or the seal abutment face is formed as a narrow facet, thereby contributing to achieving a higher flatness.

According to an alternative embodiment of the application, any two adjacent face regions of the plurality of face regions are inclined with respect to each other by an angle between 5 ° and 20 °. By means of such a relatively small angle, it is possible to achieve both a splitting of the first surface and/or the second surface and a smoother appearance of the first surface and/or the second surface.

According to an alternative embodiment of the present application, the first surface is formed by a single integral part and/or by an injection-molded part; and/or the second surface is formed from a single unitary component and/or from an injection molded part. This makes the door assembly of the domestic refrigeration appliance easy to manufacture.

According to an alternative embodiment of the present application, the seal mounting or seal abutment surface is parallel to the main plane of the door assembly. This is advantageous in simplifying the structure and achieving a good seal.

According to an alternative embodiment of the present application, the plurality of face regions of one of the first surface and the second surface includes a seal installation face, a first inclined face, and a first outer peripheral face which are arranged adjacently in this order from inside to outside with respect to the interior door cavity, wherein the first inclined face is inclined with respect to the seal installation face and the first outer peripheral face. The plurality of surface regions of the other of the first surface and the second surface include a seal abutment surface, a second inclined surface, and a second outer circumferential surface that are sequentially adjacently arranged from inside to outside with respect to the interior door cavity, wherein the second inclined surface is inclined with respect to the seal abutment surface and the second outer circumferential surface. When the outer door is in the closed position, the first outer peripheral surface faces the second outer peripheral surface, the first inclined surface faces the second inclined surface, and the seal attachment surface faces the seal abutment surface. The first surface and the second surface may have substantially complementary profiles. Thereby, the gap between the first surface and the second surface can be reduced, and a better visual effect can be provided. The first surface and the second surface are formed to have a stepped profile, which is advantageous in improving structural strength.

According to an alternative embodiment of the present application, the first outer circumferential surface and the seal mounting surface are planes parallel to each other; and/or the second peripheral surface and the seal member abutment surface are planar surfaces parallel to each other. This allows the inner and outer doors to have a smoother visual effect.

According to an alternative embodiment of the application, the first inclined surface and/or the second inclined surface are inclined in the direction of the outer door, viewed from the inside outwards with respect to the inner door cavity. This is advantageous in that the outer door has a thin thickness as viewed from the side in a state where the outer door is closed.

According to an alternative embodiment of the present application, a first free gap allowing the air flow to pass is formed between the first outer circumferential surface and the second outer circumferential surface, and a second free gap allowing the air flow to pass is formed between the first inclined surface and the second inclined surface in a state where the outer door is in the closed position. The first free gap and the second free gap are communicated to an external environment. This causes the first outer circumferential surface, the second outer circumferential surface, the first inclined surface and the second inclined surface to have a higher temperature, thereby preventing condensation from occurring there.

According to an alternative embodiment of the present application, a distance between the first outer peripheral surface and the second outer peripheral surface and/or a distance between the first inclined surface and the second inclined surface is smaller than a distance between the seal installation surface and the seal abutment surface in a case where the outer door is in the closed position. Thereby, the gas flow can be reduced to enhance the heat insulating effect.

According to an alternative embodiment of the present application, a distance between the first outer peripheral surface and the second outer peripheral surface and/or a distance between the first inclined surface and the second inclined surface is larger than a distance between the seal installation surface and the seal abutment surface in a case where the outer door is in the closed position. This causes the first outer peripheral surface, the second outer peripheral surface, the first inclined surface and the second inclined surface to have a temperature closer to the external environment, thereby helping to prevent condensation.

According to an alternative embodiment of the present application, the seal mounting face is provided with a mounting groove into which a portion of the seal is embedded. Thereby, the seal can be stably mounted.

According to an alternative embodiment of the application, the one of the first and second surfaces is formed by a thin-walled injection molded part. The door assembly may, for example, comprise a reinforcement at the mounting groove, which reinforcement is arranged on a rear side of the thin-walled injection-molded part facing away from the sealing element and extends in the longitudinal direction of the mounting groove. The reinforcing member may be formed in a U-shape surrounding the mounting groove in a section perpendicular to a longitudinal direction of the mounting groove. Such a reinforcement can effectively reinforce the structural strength of the mounting groove to reduce or prevent deformation of the reinforcement mounting groove and, thus, the seal mounting surface. This helps to ensure the sealing effect of the seal. The U-shaped reinforcement around the mounting groove has a particularly effective reinforcing effect and the positioning of the reinforcement can be achieved in a simple manner.

According to an alternative embodiment of the application, said one of the first and second surfaces comprises two first transverse sections above and below the lumen opening, respectively, and two first vertical sections on either side of the lumen opening, respectively. The other of the first and second surfaces comprises two second transverse sections located above and below the lumen opening, respectively, and two second vertical sections located on either side of the lumen opening, respectively. The first surface and the second surface may substantially completely surround the lumen opening.

According to an alternative embodiment of the present application, the door assembly includes a hinge by which the outer door is pivotably mounted to the inner door. At least one of the two first transverse sections is provided with a first hinge mounting at the first outer circumferential surface spaced apart from the first inclined surface, and at least one of the two second transverse sections is provided with a second hinge mounting at the second outer circumferential surface spaced apart from the second inclined surface, the hinges being arranged at the first hinge mounting and the second hinge mounting. The main plane parallel to the door assembly is measured in the direction from inside to outside with respect to the internal door cavity: in the two first lateral sections, the first outer peripheral surface has a size larger than the seal attachment surface and the first inclined surface, and in the two second lateral sections, the second outer peripheral surface has a size larger than the seal abutment surface and the second inclined surface. Thus, the hinge can be reliably mounted while the beautiful appearance of the inner door and the outer door is ensured.

According to an alternative embodiment of the application, the inner door is provided with a handle groove located behind the first surface, wherein the first or second outer circumferential surface of the respective one of the two first or second vertical sections of the first surface has a dimension, measured in a direction from inside to outside with respect to the inner door cavity, parallel to the main plane of the door assembly, which is greater than or equal to the depth of the handle groove. The handle groove is located right behind the first outer peripheral surface. This allows the inner door to have a compact structure.

According to an alternative embodiment of the application, one of the two first vertical sections is provided with a first electronic lock mounting portion located at the first inclined face, and one of the two second vertical sections is provided with a second electronic lock mounting portion located at the second inclined face. The door assembly comprises an electronic lock, wherein the electronic lock comprises a first electronic lock component and a second electronic lock component which are respectively installed at a first electronic lock installation part and a second electronic lock installation part, and the first electronic lock component and the second electronic lock component are oppositely arranged and mutually matched so as to mutually lock the outer door and the inner door. The main plane parallel to the door assembly is measured in the direction from inside to outside with respect to the inner door cavity: in the two first vertical sections, the size of the first inclined surface is larger than or equal to the width of the first electronic lock assembly, and in the two second vertical sections, the size of the second inclined surface is larger than or equal to the width of the first electronic lock assembly. Therefore, the use experience of the user can be improved.

According to an alternative embodiment of the present application, the main plane parallel to the door assembly is measured in an inside-out direction with respect to the inner door cavity: the dimensions of the seal mounting face, the first inclined face and the first outer peripheral face in one of the two first transverse sections are respectively equal to the dimensions of the seal mounting face, the first inclined face and the first outer peripheral face in the other of the two first transverse sections; and/or the dimensions of the seal mounting face, the first inclined face and the first peripheral face in one of the two first vertical sections are respectively equal to the dimensions of the seal mounting face, the first inclined face and the first peripheral face in the other of the two first vertical sections; and/or the dimensions of the seal abutment surface, the second inclined surface and the second outer circumferential surface in one of the two second transverse sections are respectively equal to the dimensions of the seal abutment surface, the second inclined surface and the second outer circumferential surface in the other of the two second transverse sections; and/or the dimensions of the seal abutment surface, the second inclined surface and the second peripheral surface in one of the two second vertical sections are respectively equal to the dimensions of the seal abutment surface, the second inclined surface and the second peripheral surface in the other of the two second vertical sections. Accordingly, the first surface and/or the second surface are substantially formed to be vertically symmetrical and/or horizontally symmetrical, thereby improving the visual effects of the inner door and the outer door.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the present application.

First, for ease of understanding, and returning to the description of the background section, the prior art domestic refrigeration appliance has problems of difficulty in manufacturing the inner door and/or the outer door, or of an aesthetically undesirable appearance.

In view of at least one of the above technical problems or other possible technical problems, an exemplary embodiment of the present application provides a household refrigeration appliance, including: a case having a storage chamber; a door assembly for closing a storage compartment, comprising: an inner door movably connected to the cabinet and formed with an inner door cavity having an inner door opening; an outer door movably disposed at an opposite side of the inner door from the cabinet to open and close the inner door opening, wherein a first surface of the inner door surrounding the inner door opening is opposite to a second surface of the outer door surrounding the inner door opening in a case where the outer door is in a closed position; and a seal member sandwiched between the first surface and the second surface with the outer door in the closed position. At least one of the first surface and the second surface includes a plurality of face regions, any two adjacent face regions of the plurality of face regions being different faces from each other. One of the plurality of face areas is formed as a seal mounting face on which the seal is mounted; or one of the plurality of surface portions is formed as a seal abutting surface against which the seal abuts when the outer door is in the closed position.

For a better understanding of the present application, exemplary embodiments thereof will be described below with reference to the accompanying drawings.

Before starting the detailed description, it should be pointed out that the directional terms used in the description refer to the normal use of the container for the sake of convenience of description and are not to be understood as an absolute definition of the corresponding features.

Fig. 1A, 1B and 1C schematically show perspective views of a domestic refrigeration appliance according to an exemplary embodiment of the present application.

The domestic refrigeration appliance comprises a cabinet 1 having a storage compartment 11; and a door assembly 2 for closing the storage chamber 11. The storage chamber 11 may be a refrigerating chamber, for example. The door assembly 2 includes an inner door 21 and an outer door 22. The inner door 21 is movably coupled to the cabinet 1 and is formed with an inner door cavity 211, the inner door cavity 211 having an inner door opening. The outer door 22 is movably disposed at a side of the inner door 21 opposite to the cabinet 1 to open and close the inner door opening. With the outer door 22 in the closed position, the first surface 212 of the inner door 21 surrounding the inner door opening is opposite the second surface 221 of the outer door 22 surrounding the inner door opening. The door assembly 2 is configured in the form of a "door on door". Fig. 1A shows the door assembly 2 in its entirety in a closed state in which the storage compartment 11 is closed by the door assembly 2. Fig. 1B shows the door assembly 2 in an opened state as a whole, in which the storage chamber 11 is opened. Fig. 1C shows a state where the inner door 21 is closed and the outer door 22 is opened, in which the inner door cavity 211 is opened at the front.

As can be seen in fig. 1C, the door assembly 2 further comprises a seal 23 which is sandwiched between the first surface 212 and the second surface 221 with the outer door 22 in the closed position. The outer door 22 and the inner door 21 are sealingly connected by a seal 23. At least one of the first surface 212 and the second surface 221 includes a plurality of face regions 3, any two adjacent face regions 3 of the plurality of face regions 3 being non-coplanar with each other. One of the plurality of face regions 3 is formed as a seal mounting face 31, and the seal 23 is mounted on the seal mounting face 31. Alternatively or additionally, one of the plurality of face regions 3 is formed as a seal abutment face 32, the seal 23 abutting on the seal abutment face 32 with the outer door 22 in the closed position.

By dividing the first surface 212 and/or the second surface 221 into a plurality of surface regions 3 that are not coplanar with each other, the first surface 212 and/or the second surface 221 having a larger area can be divided into surface regions 3 having a smaller area. On the one hand, this is advantageous in that the surface region 3 having a smaller area has a higher flatness. This is particularly important for the seal attachment face 31 and the seal abutment face 32, since the flatness of the seal attachment face 31 and the seal abutment face 32 will affect the sealing effect of the seal 23. For example, by dividing the first surface 212 into a plurality of surface regions 3 including the seal attachment surface 31, the flatness of the seal attachment surface 31 within 1mm can be ensured in a simple manner. Thus, the seal attachment surface or the seal contact surface having a high flatness can be manufactured in a simple manner, and the difficulty in manufacturing can be reduced. On the other hand, such a splitting enables the first surface 212 and/or the second surface 221, which is otherwise visually wide, to create a relatively narrow and stereoscopic visual effect, making the inner door 21 and/or the outer door 22 more attractive. Additionally, the first and/or

second surfaces

212, 221 that are subject to disassembly may have greater structural strength relative to being integrally formed as a single plane.

In this embodiment, the domestic refrigeration appliance can be implemented, for example, as a combined refrigerator having a refrigerating compartment and a freezing compartment. Those skilled in the art will appreciate that the present invention is equally applicable to other types of refrigerators, such as stand-alone refrigerators or freezers. In addition, the present invention can also be applied to other household refrigeration appliances than refrigerators, such as wine chests, as needed.

The invention is further described below in conjunction with fig. 2A and 2B. Fig. 2A and 2B schematically show an inner door 21 and an outer door 22, respectively, of a domestic refrigeration appliance according to an exemplary embodiment of the present invention, wherein fig. 2A shows a side of the inner door 21 facing the outer door 22 and fig. 2B shows a side of the outer door 22 facing the inner door 21.

As shown in fig. 2A, the first surface 212 is detachable into a plurality of face regions 3 including the seal abutment face 32. The seal abutment surface 32 is located adjacent to the inner side of the inner door cavity 211 as compared to other surface regions of the plurality of surface regions 3 of the first surface 212 except for the seal abutment surface 32. This helps to improve the sealing and insulating effect of the seal. The other face region located on the outer side with respect to the seal abutment face 32 may have a higher temperature to prevent condensate from forming at the other face region.

Alternatively, each of the other face regions has a size (hereinafter also referred to as "width") equal to the width of the seal abutting face 32, measured in the inside-out direction with respect to the inner door cavity 211, in parallel to the principal plane of the door assembly 2. Thereby, the first surface 212 can be substantially evenly divided, so that the first surface 212 has a neat and generous appearance.

Alternatively, each of the other surface regions has a width greater than that of the seal abutment surface 32, measured in an inside-out direction with respect to the inner door cavity 211, parallel to the principal plane of the door assembly 2. This is advantageous in ensuring that the seal member abutment surface 32 is formed into a narrow facet, thereby contributing to achieving a higher flatness of the seal member abutment surface 32.

The first surface 212 may include, for example, a seal abutment surface 32, a second inclined surface 35, and a second outer circumferential surface 36, which are adjacently arranged in order from inside to outside with respect to the inner door cavity 211. The second inclined surface 35 is inclined with respect to the seal abutment surface 32 and the second outer peripheral surface 36.

As shown in fig. 2B, the second surface 221 is separable into a plurality of face regions 3 including the seal mounting face 31. The seal mounting face 31 is located adjacent an inner side of the interior door cavity 211 as compared to other face areas of the plurality of face areas 3 of the second surface 221 except for the seal mounting face 31.

Alternatively, each of the other face regions has a width equal to that of the seal mounting face 31, measured in an inward-outward direction with respect to the interior door cavity 211, parallel to the main plane of the door assembly 2, so as to give the first face 212 a cleaner profile, and each of the other face regions has a width greater than that of the seal mounting face 31, measured in an inward-outward direction with respect to the interior door cavity 211, parallel to the main plane of the door assembly 2. This is advantageous in ensuring that the seal mounting face 31 is formed as a narrow facet, thereby contributing to achieving a higher flatness.

The second surface 221 may include, for example, the seal installation surface 31, the first inclined surface 33, and the first outer peripheral surface 34, which are adjacently arranged in order from inside to outside with respect to the inner door cavity 211. The first inclined surface 33 may be inclined with respect to the seal abutment surface 32 and the first outer peripheral surface 34.

Optionally, the seal mounting face 31 and/or the seal abutment face 32 are parallel to the main plane of the door assembly 2. This is advantageous in simplifying the structure and achieving a good seal.

In particular, when the outer door 22 is in the closed position, the first outer peripheral surface 34 faces the second outer peripheral surface 36, the first inclined surface 33 faces the second inclined surface 35, and the seal attachment surface 31 faces the seal attachment surface 31.

It should be understood that in further embodiments, the first surface 212 of the inner door 21 may also include the seal mounting surface 31, and/or the second surface 221 of the outer door 22 may include the seal mounting surface 31.

The first surface 212 and/or the second surface 221 may each be formed from a single, unitary component. For example, the first surface 212 may be at least a portion of an outer surface of the outer shell of the inner door 21, and the first surface 212 may be at least a portion of an outer surface of the inner bladder of the outer door 22. The outer shell of the inner door 21 and/or the inner bladder of the outer door 22 may be formed as injection molded parts. In other words, the first surface 212 and/or the second surface 221 can be formed, for example, by injection molding, in particular by thin-walled injection molding.

As can be seen in fig. 2A and 2B, the first surface 212 may include two first lateral sections 2121 located above and below the lumen opening, respectively, and two first vertical sections 2122 located on (left and right) sides of the lumen opening, respectively. The second surface 221 can include two second transverse sections 2211 above and below the interior cavity opening, respectively, and two second vertical sections 2212 on (left and right) sides of the interior cavity opening, respectively.

The dimensions of the seal mounting face 31, the first inclined face 33 and the first outer peripheral face 34 in one of the two first lateral sections 2121 are respectively equal to the dimensions of the seal mounting face 31, the first inclined face 33 and the first outer peripheral face 34 in the other of the two first lateral sections 2121, measured in an inward-outward direction with respect to the interior door cavity 211, parallel to the principal plane of the door assembly 2; and/or the dimensions of the seal mounting face 31, the first inclined face 33 and the first peripheral face 34 in one of the two first vertical sections 2122 are respectively equal to the dimensions of the seal mounting face 31, the first inclined face 33 and the first peripheral face 34 in the other of the two first vertical sections 2122; and/or the size of the seal abutment surface 32, the second inclined surface 35, and the second outer circumferential surface 36 in one of the two second transverse sections 2211 are respectively equal to the size of the seal abutment surface 32, the second inclined surface 35, and the second outer circumferential surface 36 in the other of the two second transverse sections 2211; and/or the size of the seal abutment surface 32, the second inclined surface 35, and the second peripheral surface 36 in one of the two second vertical sections 2212 are respectively equal to the size of the seal abutment surface 32, the second inclined surface 35, and the second peripheral surface 36 in the other of the two second vertical sections 2212. Therefore, the first surface 212 and the second surface 221 are formed substantially in up-down symmetry or left-right symmetry.

Referring to fig. 1C, the door assembly 2 may include a hinge 25, and the outer door 22 may be pivotably mounted to the inner door 21 by the hinge 25. At least one of the two first lateral sections 2121 may be provided with a first hinge mount 2123 at the first peripheral face 34 spaced from the first inclined face 33. At least one of the two second transverse sections 2211 can be provided with a second hinge mount 2213 at the second peripheral surface 36 spaced from the second inclined surface 35. The hinge 25 may be disposed at the first hinge mount 2123 and the second hinge mount 2213. The width of the first outer peripheral surface 34 is larger than the widths of the seal mounting surface 31 and the first inclined surface 33 in the two first lateral sections 2121, and the width of the second outer peripheral surface 36 is larger than the widths of the seal abutment surface 32 and the second inclined surface 35 in the two second lateral sections 2211, as measured in the direction from inside to outside with respect to the inner door cavity 211, in parallel to the principal plane of the door assembly 2. This facilitates the arrangement of the first hinge mount 2123 and the second hinge mount 2213.

The door assembly 2 may further include an electronic lock 26, the electronic lock 26 including first and second electronic lock assemblies 261 and 262 respectively mounted on the inner and

outer doors

21 and 22, the first and second electronic lock assemblies 261 and 262 being disposed opposite to each other and cooperating with each other so as to mutually lock the outer and

inner doors

22 and 21. The electronic lock 26 may be unlocked, for example, by a switch, such as a key, provided on the outer door 22.

Alternatively, one of the two first vertical sections 2122 is provided with a first electronic lock mount 2124 at the first inclined face 33, and one of the two second vertical sections 2212 is provided with a second electronic lock mount 2214 at the second inclined face 35. The first and second electronic lock assemblies 261 and 262 may be mounted at the first and second electronic

lock mounting portions

2124 and 2214, respectively.

The width of the first inclined surface 33 in the two first vertical sections 2122 may be greater than or equal to the width of the first electronic lock assembly 261, and the width of the second inclined surface 35 in the two second vertical sections 2212 may be greater than or equal to the width of the first electronic lock assembly 261, measured in the inward-outward direction with respect to the inner door cavity 211, in parallel to the main plane of the door assembly 2.

Fig. 3A schematically showsbase:Sub>A sectional view along the sectionbase:Sub>A-base:Sub>A of the door assembly 2 of the domestic refrigeration appliance shown in fig. 1A. Fig. 3B schematically shows an enlarged view of the circled portion in fig. 3A.

As can be seen from fig. 3A and 3B, in this embodiment, the first outer peripheral surface 34 and the seal installation surface 31 may be formed as planes parallel to each other; the second outer circumferential surface 36 and the seal member abutment surface 32 may be formed as planes parallel to each other. This provides a relatively flat visual effect on the inner door 21 and the outer door 22.

The first inclined surface 33 and/or the second inclined surface 35 may be inclined in a direction toward the outer door 22, as viewed from the inside to the outside with respect to the inner door cavity 211. This is advantageous in that the outer door 22 has a thin thickness as viewed from the side in a state where the outer door 22 is closed.

For example, any two adjacent face areas 3 of the plurality of face areas 3 of the first surface 212 or the second surface 221 may be inclined relative to each other by an angle between 5 ° and 20 °.

When the outer door 22 is in the closed position, a first free gap 4 allowing airflow is formed between the first outer peripheral surface 34 and the second outer peripheral surface 36, and a second free gap 5 allowing airflow is formed between the first inclined surface 33 and the second inclined surface 35. This means that the sealing member 23 is no longer arranged between the first outer circumferential surface 34 and the second outer circumferential surface 36 and between the first inclined surface 33 and the second inclined surface 35. The first free gap 4 and the second free gap 5 are connected to the external environment. This causes the first outer peripheral surface 34, the second outer peripheral surface 36, the first inclined surface 33 and the second inclined surface 35 to have a higher temperature, thereby preventing condensation from occurring there.

Alternatively, in the case where the outer door 22 is in the closed position, the distance between the first outer peripheral surface 34 and the second outer peripheral surface 36 and/or the distance between the first inclined surface 33 and the second inclined surface 35 may be larger than the distance between the seal installation surface 31 and the seal abutment surface 32. This causes the first outer peripheral surface 34, the second outer peripheral surface 36, the first inclined surface 33 and the second inclined surface 35 to have a temperature closer to the external environment, thereby helping to prevent condensation.

In an exemplary embodiment, the spacing between the first and second outer

peripheral surfaces

34 and 36 and/or the spacing between the first and second

inclined surfaces

33 and 35 may be less than the spacing between the seal mounting surface 31 and the seal abutment surface 32 with the outer door 22 in the closed position. Thereby, the gas flow can be reduced to enhance the heat insulating effect.

As can be seen from fig. 3B, the packing installation face 31 is provided with, for example, an installation groove 311, and a part of the packing 23 is insertable into the installation groove 311, so that the packing 23 can be stably installed.

Fig. 3C provides a further enlarged view of the door assembly 2 shown in fig. 3B at the seal mounting surface 31. As described above, the second surface 221 may be formed from a thin-walled injection molded piece. The door assembly 2 may further include a reinforcement 24 at the mounting groove 311. The reinforcement 24 is arranged on the rear side of the thin-walled injection-molded part facing away from the sealing element 23 and extends in the longitudinal direction of the mounting groove 311. In a section perpendicular to the longitudinal direction of the mounting groove 311, the reinforcement 24 is formed in a U shape surrounding the mounting groove 311. Such a reinforcement member 24 can effectively reinforce the structural strength of the mounting groove 311 to reduce or prevent deformation of the reinforcement mounting groove 311 and, thus, the seal mounting surface 31. This helps to ensure the sealing effect of the seal 23. The U-shaped reinforcement 24 around the mounting slot 311 has a particularly effective reinforcing effect and the positioning of the reinforcement 24 can be achieved in a simple manner.

Fig. 4 schematically shows a sectional view along the section B-B of the door assembly 2 of the domestic refrigeration appliance shown in fig. 2A.

In this embodiment, the inner door 21 may be provided with a handle slot 213 (shown in phantom in FIG. 2A) located rearward of the first surface 212, for example. The handle groove 213 is recessed inward from the side of the inner door 21. The width of the first outer peripheral surface 34 of the two first vertical sections 2122 of the first surface 212, measured in a direction from inside to outside with respect to the inner door cavity 211, parallel to the main plane of the door assembly 2, is equal to or greater than the depth (measured in the same direction) of the handle groove 213. Therefore, the handle groove 213 is located directly behind the first outer peripheral surface 34. This contributes to a compact structure of the inner door 21.

Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure, even if only a single embodiment is described with respect to a particular feature. The characteristic examples provided in the disclosure of the present application are intended to be illustrative, not limiting, unless stated differently. In the specific implementation, a plurality of features can be combined with each other according to actual needs, where technically feasible. In particular, features from different embodiments may also be combined with one another. Various substitutions, alterations, and modifications may be conceived of without departing from the spirit and scope of the present application.
