The positional relationship of the constituent elements is appropriately changed according to the direction in which each constituent element is described. Therefore, the present invention is not limited to the words described in the specification, and may be appropriately replaced according to circumstances. Here, defined in terms of XYZ rectangular coordinate system in the drawings: the X direction corresponds to the width direction of the refrigerator 100, the Y direction corresponds to the depth direction of the refrigerator 100, and the Z direction corresponds to the height direction of the refrigerator 100.

Fig. 1 illustrates a perspective view of a refrigeration appliance 100 according to an exemplary embodiment of the present invention. Here, the refrigerator 100 is, for example, a multi-door refrigerator.

As shown in fig. 1, the refrigerator 100 includes a door 110 and a supporter 120. The door 110 may be rotatably coupled to the support 120 by a hinge assembly 130.

Here, the support 120 may be a case 121 having a storage compartment, the door 110 closing at least a portion of the storage compartment, the door 110 being rotatably connected to the case 121 by a hinge assembly 130. In an alternative embodiment, the support 120 may also include another door disposed in a depth direction of the refrigerator 100 with the door 110 and connected through the hinge assembly 130. For example, the support 120 may include an inner door (not shown herein) between the door 110 and the case 121, thereby forming a double door configuration in which the inner door and the case 121 form a first storage space and the door 110 and the inner door form a second storage space, thereby achieving division of different storage spaces, and the door 110 is connected to the inner door through the hinge assembly 130 so that a user can access the second storage space.

Fig. 2a and 2b respectively show partial views of the refrigerator 100 according to an exemplary embodiment of the present invention, wherein the door 110 and the support 120 of the refrigerator 100 are in a state of being separated from each other in fig. 2a, and the door 110 and the support 120 of the refrigerator 100 are in a state of being assembled with each other in fig. 2 b. Illustratively, as shown in fig. 2a and 2b, the door 110 includes a door body 10 having an insulating glass unit 101. The door body is a main body of the door 110, and the door body occupies at least most of the user's line of sight when viewed in the depth direction Y of the refrigerator 100.

Here, the insulating glass unit 101 includes a first glass plate 11 and a second glass plate 12 spaced apart from each other, wherein the first glass plate 11 is located in front of the second glass plate 12 as viewed in the depth direction Y.

Illustratively, the first glass pane 11 and the second glass pane 12 may be provided with sealing means 13 in the edge region such that an insulating chamber is formed between the first glass pane 11 and the second glass pane 12, said sealing means being seen in fig. 5a. In particular, a vacuum is drawn between the first glass plate 11 and the second glass plate 12, whereby the insulating glass unit 101 is constructed as a double vacuum glass unit, thereby achieving a good insulating effect. Further, a plurality of spacers may be provided between the first glass plate 11 and the second glass plate 12 to maintain the distance between the first glass plate 11 and the second glass plate 12.

As shown in fig. 2a and 2b, a hinge assembly 130 is connected to the rear side of the door body 10. Here, the hinge assembly 130 includes a first hinge mechanism 20 at the rear side of the door body 10 and a second hinge mechanism 30 connected to the support body 120, and the door 110 or the door body 10 can be pivotally connected to the support body 120 by the cooperation of the first hinge mechanism 20 and the second hinge mechanism 30, thereby achieving the assembly and normal opening and closing of the door body 10. Here, the first hinge mechanism 20 may be coupled to the rear side of the door body 10 or at least a portion may be integrally formed at the rear side of the door body 10 to be disposed at the rear side of the door body 10.

In the prior art, the top of the door body 10 is generally used to arrange a hinge mechanism, for example, the top of the door body may be provided with a shaft hole opened at the top surface 102 of the door body to insert a hinge shaft or the hinge mechanism may extend above the top surface 102 of the door body to be fixed to the top surface 102 of the door body. In contrast, in the exemplary embodiment according to the present invention, since the first hinge mechanism 20 is disposed at the rear side of the door body 10 instead of the top side or the bottom side, the first hinge mechanism 20 may be disposed regardless of the thickness of the door body 10 and the top and bottom structures of the door body 10, which allows the door body 10 to be constructed thinner and more free in design, thereby providing for a reduction in the thickness of the refrigerator 100 and a corresponding increase in the storage space inside the refrigerator 100. For example, when the first hinge mechanism 20 is disposed at the rear side of the door body 10, there is no need to provide a shaft hole or a fixed hinge mechanism at the top or bottom of the door body 10, and the door body 10 does not have to reach a corresponding thickness in order to secure the disposition of the hinge mechanism. In addition, the arrangement of the first hinge mechanism 20 at the rear side of the door body 10 is advantageous in preventing the user from directly seeing the hinge mechanism 20 from the front side of the door 110 in the depth direction Y, and also in improving the external appearance effect of the refrigerator.

Illustratively, the end faces 103 of the first and second glass plates 11, 12 on at least one side of the door 110 are exposed to the exterior of the door 110. Here, the end surface 103 may be a left and right end surface of the door body 10, or may be an upper and lower end surface of the door body 10, the upper end surface being a top surface 102 of the door body 10 and the lower end surface being a bottom surface of the door body 10. In particular, the end faces 103 of the first glass plate 11 and the second glass plate 12 are exposed to the outside of the door on at least one side of the door. In some embodiments, the end surfaces 103 on the left and right sides of the first glass sheet 11 and the second glass sheet 12 are substantially exposed outside the door. In particular, on each side of the door body 10, the end faces 103 of the first glass plate 11 and the second glass plate 12 are exposed to the outside of the door 110, whereby the entire door body 10 is free from the need for providing a frame covering the side end faces of the first glass plate 11 and the second glass plate 12, so that the size of the door body 10 is made more compact, in particular, the size of the door body 10 at the edges can be made smaller, the possibility of interference of a refrigerator having such a door with surrounding furniture at the time of opening and closing the door can be lower, and furthermore, it can be extremely compact in visual sense. Here, the first hinge mechanism 20 is located at a side edge of the door 110 where the first glass plate 11 and the second glass plate 12 are flush. Thereby achieving a flush end face 103 of the door body 10.

Illustratively, the insulating glass unit 101 is provided with a cover layer at least at a position corresponding to the first hinge mechanism 20, by which the user can be effectively prevented from seeing the first hinge mechanism 20 located at the rear side of the door body 10 through the insulating glass unit 101 from the front side of the door 110, thereby improving the external appearance of the refrigerator 100. Here, a cover layer may be printed on the first glass plate 11 and/or the second glass plate 12 to make the insulating glass unit 101 opaque in a region corresponding to the first hinge mechanism 20. The cover layer may be disposed on the front side or the rear side of either or both of the first glass plate 11 and the second glass plate 12.

Thus, embodiments of the present invention may realize a refrigeration appliance 100 comprising a door body 10, the door body 10 comprising an insulating glass unit 101 comprising a first glass sheet 11 and a second glass sheet 12 disposed in spaced apart relation, wherein the first glass sheet 11 is positioned in front of the second glass sheet 12, and edges of the first glass sheet 11 and the second glass sheet 12 are exposed to the exterior of the door body 10 on at least one side of the door body 10. Here, the door body 10 is pivotably connected to the support body 120 by a hinge assembly 130 including a first hinge mechanism 20 and a second hinge mechanism 30 adapted to be fitted to each other, wherein the first hinge mechanism 20 is disposed on the rear side of the door body 10 and may be coupled to the rear side of the door body 10 or at least a portion integrally formed on the rear side of the door body 10, and the second hinge mechanism 30 is disposed in the support body 120.

As illustrated in fig. 2a and 2b, the first hinge mechanism 20 at the rear side of the door 110 includes a hinge shaft 1, and the second hinge mechanism 30 of the support body 120 includes a shaft hole 2, wherein in an assembled state of the door 110 and the support body 120, the hinge shaft 1 is inserted into the shaft hole 2, thereby achieving hinge connection of the door body 10 and the support body 120.

The first hinge mechanism 20 may include a hinge bracket 21 fixed to the rear side of the door body 10, which is constructed to be bent and has a fitting portion 3 fixed to the rear side of the door body 10. The hinge bracket 21 of the first hinge mechanism 20 may further include a connection portion 22 bent from one end of the fitting portion 3 and extended backward, and a hinge shaft 1 is connected to one end of the connection portion 22 to be inserted into the shaft hole 2 of the second hinge mechanism 30. The fitting portion 3, which may be plate-shaped and substantially parallel to the rear surface of the door body 10, includes a fitting surface toward the front surface of the door body 10, which is connected to the rear side of the door body 10, is spaced apart in parallel with the hinge shaft 1 and is abutted against the door 110, particularly the rear side of the door body 10, when fitted, and the shaft hole 2 is directly provided in the support body 120 and has a top surface opened to the support body 120. Of course, other configurations which are considered to be of interest by the person skilled in the art are also conceivable, for example, in which the second hinge mechanism 30 is constructed separately from the body of the support body 120 and is fastened to one another.

Illustratively, the first hinge mechanism 20 is adhesively secured to the rear side of the door 110 by an adhesive between the fitting portion 3 and the rear side of the door. It is also contemplated that the first hinge mechanism 20 may be secured to the rear side of the door 110 in a welded manner or otherwise in a manner deemed expedient by those skilled in the art.

Illustratively, as shown in fig. 2b, the first hinge mechanism 20 is disposed in an upper region of the door 110 near the top surface 102, and the second hinge mechanism 30 is disposed on an upper end surface of the support 120. It is of course conceivable that the door 110 comprises two first hinge mechanisms 20 and the carrier 120 comprises two second hinge mechanisms 30, respectively, wherein the two first hinge mechanisms 20 are arranged in the height direction Z in the upper part region of the door 110 close to the top surface 102 and in the lower part region close to the bottom surface, respectively, and the two second hinge mechanisms 30 are arranged on the upper end face and the lower end face of the carrier 120, respectively. This enables the door body 10 to be reliably fixed to the support 120.

Illustratively, as shown in fig. 2, the top surface 102 of the door 110 extends upwardly beyond the upper end surface of the support 120 as viewed in the height direction Z. Accordingly, the lower end surface of the door 110 may protrude downward beyond the lower end surface of the support 120, thereby completely covering the support 120 in the height direction Z by the door 110, thereby enhancing the external appearance effect of the refrigerator 100.

Fig. 3a and 3b illustrate partial views of a refrigerator 100 according to another exemplary embodiment of the present invention, wherein fig. 3a illustrates only a door 110 of the refrigerator 100, and fig. 3b illustrates a state in which the door 110 and a support 120 of the refrigerator 100 are assembled with each other.

As shown in fig. 3a and 3b, the first glass plate 11 and the second glass plate 12 may be offset by a distance 4 at the edge of at least one side of the door 110, at which side the first glass plate 11 extends beyond the second glass plate 12 by the distance 4. By providing a space 4 between the edges of the first 11 and second 12 glass plates, the mounting of the first hinge mechanism 20 on the rear side of the insulating glass unit 101 is facilitated.

Illustratively, the first hinge mechanism 20 is located within the space 4 and is coupled to the rear surface of the first glass plate 11. As a result, the first hinge mechanism 20 can be at least partially overlapped with the second glass plate 12 in the depth direction Y and the space between the door 10 and the support 120 can be reduced, thereby further reducing the thickness of the entire refrigeration appliance 100.

As shown in fig. 3a and 3b, the first hinge mechanism 20 at the rear side of the door 110 includes a hinge base 23 fixed to the rear side of the door body 10, the hinge base including a shaft hole 2 configured to receive a hinge shaft 1 of the second hinge mechanism 30, the hinge shaft being inserted into the shaft hole 2 in an assembled state of the door 110 and the support body 120, thereby achieving hinge connection of the door body 10 and the support body 120. The first hinge mechanism 20 is configured in the form of a hollow cylinder and the shaft bore 2 can be configured as a through-hole or blind bore, the first hinge mechanism 20 resting against the rear side of the door 110 via the mounting surface 3, while the second hinge mechanism 30 is configured, for example, in the form of a plate and comprises a further mounting surface 5, from which the hinge shaft 1 protrudes perpendicularly, wherein the further mounting surface 5 of the second hinge mechanism 30 rests against the upper or lower end face of the support body 120 and is fastened to the support body 120, for example, by means of a screw.

As shown in fig. 3a and 3b, the door body 10 is embodied as an insulating glass unit 101, which comprises a first glass pane 11 and a second glass pane 12 spaced apart from one another, wherein the first glass pane 11 is located in front of the second glass pane 12, wherein the first glass pane 11 exceeds the second glass pane 12 in the height direction Z. In this case, the first glass pane 11 also extends beyond the support 120 and the second hinge mechanism 30 fixedly connected to the support 120 in the height direction Z.

Fig. 4a shows a partial view of a door 110 of a refrigerator appliance 100 according to another exemplary embodiment of the present invention, and fig. 4b shows an exploded view of fig. 4 a.

Illustratively, as shown in fig. 4a and 4b, the door body 10 includes a mounting portion 6 for mounting the first hinge mechanism 20, which is located at the rear side of the second glass pane 12 of the insulating glass unit 101. However, it is also conceivable for the mounting part 6 to be located on the rear side of the first glass pane 11 of the insulating glass unit 101, in which case the mounting part 6 is arranged in the distance 4 between the edges of the first glass pane 11 and the second glass pane 12.

Illustratively, as shown in fig. 4a and 4b, when the first hinge mechanism 20 is coupled to the upper portion of the door body 10, the mounting portion 6 of the door body 10 for mounting the hinge mechanism 20 is located at the rear side of the door body 10 and below the top surface 102 of the door body 10. The hinge assembly 130 including the first hinge mechanism 20 and the second hinge mechanism 30 may be entirely not higher than the top surface 102 of the door body 10 in the height direction of the door body 10, and in particular, the hinge assembly 130 may be entirely lower than the top surface 102 of the door body 10 so as not to be easily seen by a user positioned in front of the door 110.

Similarly, when the first hinge mechanism 20 is connected to the lower portion of the door body 10, the mounting portion 6 of the door body 10 to mount the hinge mechanism may be located at the rear side of the door body 10 and higher than the bottom surface (not shown here) of the door body 10, which is opposite to the top surface 102 of the door body 10 in the height direction Z. The first hinge mechanism 20 as a whole may be not lower than the bottom surface of the door body 10 in the height direction of the door body 10. In particular, the hinge assembly 130 including the first hinge mechanism 20 and the second hinge mechanism 30 may be integrally higher than the bottom surface of the door body 10, so that the hinge assembly 130 is not easily visible to a user positioned in front of the door 110.

Illustratively, as shown in fig. 4a and 4b, the mounting portion 6 of the door body 10 is configured as a recess 7 which is opened from the rear side toward the front side of the insulating glass unit 101 to receive the fitting portion 3 of the first hinge mechanism 20, thereby more firmly fixing the first hinge mechanism 20 to the insulating glass unit 101. The mounting portion 3 of the first hinge mechanism 20 is at least partially immersed in the mounting portion 6 formed as a recess 7, and an adhesive material is provided between the mounting portion 3 and the inner surface of the recess 7, in particular the bottom surface of the recess 7 facing the support 120, so that the first hinge mechanism 20 is adhesively coupled to the rear side of the insulating glass unit 101. Here, the lower portion of the fitting portion 3 may be supported on the recess portion 7, particularly on the bottom surface of the recess portion 7, and the adhesive material may be disposed along different surfaces of the fitting portion 3, thereby improving reliability of fixing the first hinge mechanism 20 to the rear side of the insulating glass unit 101 from different directions.

In one exemplary embodiment, the mounting portion 6 for securing the first hinge mechanism 20 is disposed on the rear side of the second glass sheet 12 such that the first hinge mechanism 20 is secured to the rear side of the second glass sheet 12. This facilitates the flush arrangement of the edges of the first glass plate 11 and the second glass plate 12 in the vicinity of the first hinge mechanism 20. As shown in fig. 4a and 4b, the left/right side edges of the first glass plate 11 and the second glass plate 12 are substantially flush, and the upper side edges of both are also substantially flush. In particular, the left/right side end faces of the first glass plate 11 and the second glass plate 12 and the upper side end faces thereof are at least partially located in the same plane. This is particularly advantageous for expanding the coverage of the insulating glass unit 101 of the door body 10 relative to the support 120, for example the insulating cavity of the insulating glass unit 101 may extend significantly beyond the open contour of the storage compartment of the refrigeration appliance 100, thereby improving the performance of the refrigeration appliance 100, in particular reducing the risk of condensation of the door 110.

Illustratively, the door body 10 and the first hinge mechanism 20 of the door 110 are first assembled together as a pre-assembled unit and then assembled to the support 120 to collectively constitute the refrigerator 100.

Fig. 5a shows a cross-sectional view of a door 110 of a refrigerator appliance 100 according to another exemplary embodiment of the present invention, and fig. 5b shows a perspective view of fig. 5 a.

As shown in fig. 5a, the door 110 includes a door body 10 having an insulating glass unit 101 including a first glass sheet 11 and a second glass sheet 12 spaced apart from each other, wherein the first glass sheet 11 is positioned in front of the second glass sheet 12. The first glass pane 11 and the second glass pane 12 are provided with sealing means 13 in the edge region so that an insulating chamber is formed between the first glass pane 11 and the second glass pane 12. In particular, a vacuum is drawn between the first glass plate 11 and the second glass plate 12, whereby the insulating glass unit 101 is constructed as a double vacuum glass unit, thereby achieving a good insulating effect. Further, a plurality of spacers may be provided between the first glass plate 11 and the second glass plate 12 to maintain the distance between the first glass plate 11 and the second glass plate 12.

Illustratively, as shown in fig. 5a and 5b, the door body 10 of the door 110 may illustratively include a rim 14 that surrounds at least a portion of the edge of the door body 10. Here, the frame 14 forms a U-shaped clamping groove which opens toward the insulating glass unit 101 of the door body 10, whereby the frame can fix the door body 10 in a clamped manner and the first hinge mechanism 20 can be fixed on the end side of the frame facing the support body 120. The bezel 14 may form a portion of the top, bottom, left, and/or right sides of the door body 10. The bezel 14 may extend to the rear side of the door body 10 to arrange the first hinge mechanism 20 at the rear side of the door body 10. By a reasonable choice of materials and construction of the frame 14, the technical difficulty of coupling the first hinge mechanism 20 to the door body 10 is advantageously reduced.

Illustratively, the bezel 14 extends continuously over the entire side edge of the door body 10. However, it is also conceivable for the frame 14 to surround part of the edge of the door body 10 in sections, for example for the frame section to be provided only at the location where the first hinge mechanism 20 is to be mounted.

Illustratively, as shown in fig. 5b, the mounting portion 6 to mount the first hinge mechanism 20 is disposed at the rear side of the frame 14 surrounding the first and second glass sheets 11 and 12 of the insulating glass unit 101, so that the first hinge mechanism 20 can be coupled to the rear side of the frame 14. Here, the mounting portion 6 may be configured as a recess portion 7 that is opened from the rear side toward the front side of the insulating glass unit 101. The fitting portion 3 of the first hinge mechanism 20 may be sunk into the mounting portion 6 configured as the recess portion 7 so as to be mounted on the rear side of the bezel 14 by assembly. It is contemplated that at least a portion of first hinge mechanism 20 may be integrally formed with frame 14.
