DETAILED DESCRIPTION

[0035] Referring now to the figures of the drawing in detail and first, particularly, to FIGS. 1 and 2 thereof, there is shown a refrigerator. The refrigerator includes a case body 10 having a storage compartment 11, an inner door 20 rotatably disposed (i.e., articulated, pivotal) in front of the case body 10, and an outer door 30, where the outer door 30 is rotatably disposed (i.e., articulated, pivotal) in front of the inner door 20.

[0036] Storage space may be provided in the inner door 20 to store an item, the storage space thereof has an opening 20a towards the outer door 30, and the outer door 30 is configured to open or close the opening 20a.

[0037] In the present invention, the term front and back respectively represent a front portion and a rear portion along a front-and-rear direction of the door.

[0038] The outer door 30 has a heat-insulation portion 31 configured to seal the opening 20a, to prevent the storage compartment 11 from exchanging with external heat through the opening 20a. The outer door 30 includes a front door panel 32, the front door panel 32 includes a cover portion 33 extending out of the heat-insulation portion 31 along a width direction of the outer door 30, to form allowance space 12 at the back of the cover portion 33.

[0039] The inner door 20 may include a protruding portion 22 extending into the allowance space 12. The protruding portion 22 may include a handle portion 22a configured to open the outer door 30. At least a part of the handle portion 22a is covered by the cover portion 33. From the perspective of a form, the handle portion 22a may use a form of a handle recess or a handle, and a handle recess is used in this embodiment.

[0040] In an embodiment, the front door panel 32 may be a component of the heat-insulation portion 31. In another embodiment, the front door panel 32 is not a component of the heat-insulation portion 31, for example, the front door panel 32 is only configured to decorate the outer door 30.

[0041] As shown in FIG. 2, the heat-insulation portion 31 may include a heat-insulation glass module 31a and a doorframe 31b disposed around the heat-insulation glass module 31a, and the front door panel 32 is disposed in front of the doorframe 31b. A heat-insulation cavity 31d is provided in the doorframe 31b. The heat-insulation cavity 31d may be filled with foamed materials or be closed heat-insulation space.

[0042] In this embodiment, heat-insulation space is formed between the front door panel 32 and the heat-insulation glass module 31a. In some other embodiments, the front door panel 32 together with at least one glass plate located behind the front door panel 32 may form the heat-insulation glass module 31a. In these embodiments, the front door panel 32 is a component of the heat-insulation portion 31.

[0043] In this embodiment, the cover portion 33 is located on a longitudinal side of the outer door 30, the front door panel 32 exceeds out of the doorframe 31b of the heat-insulation portion 31 along the width direction of the outer door 30 to form the cover portion 33. It is easy to understand that in an alternative embodiment, when the cover portion 33 is located on a transversal side of the outer door 30, the front door panel 32 exceeds out of the doorframe 31b of the heat-insulation portion 31 along a height direction of the outer door 30 to form the cover portion 33.

[0044] In this embodiment, the cover portion 33 is an integral part of the front door panel 32. In an alternative embodiment, the cover portion 33 may be a part that is manufactured separately to be assembled in a main part of the front door panel 32.

[0045] The doorframe 31b may include several borders (not shown) that extend along the length direction and the width direction, and the borders may be formed by processes such as an extrusion process and an injection molding process. In this embodiment, the borders are extruding members.

[0046] The inner door 20 includes a door body 21 surrounding the opening 20a, and the door body 21 may be filled with foamed heat-insulation materials.

[0047] The outer door 30 includes a protecting plate 34, and the protecting plate 34 is connected to a rear side of the cover portion 33 and faces the inner door 20. From the perspective of a connection manner, the protecting plate 34 may be attached to the rear surface of the cover portion 33 by means of adhesion or other manners. From the perspective of materials, the protecting plate 34 may be a plastic plate.

[0048] It can be seen from FIG. 2 that, along the front-and-rear direction of the door, the protecting plate 34 is located between the cover portion 33 and the handle portion 22a of the inner door 20. There is a gap between the handle portion 22a and the protecting plate 34 in the front-and-rear direction.

[0049] The solution has the following advantages: Strength of the cover portion 33 extending out of the doorframe 31b in the front door panel 32 is relatively weak. The protecting plate 34 is connected to the back of the cover portion 33. On one hand, the strength of the cover portion 33 can be improved, and on the other hand, a protection function can be achieved, thereby preventing a backside of the cover portion 33 from being polluted when the backside of the cover portion 33 is directly touched by a user. In particular, when the front door panel 32 uses a glass plate, the protecting plate 34 is beneficial to preventing a backside of the front door panel 32 from being exposed in an environment that may be touched by the user, thereby preventing the backside of the front door panel from being maintained a fingerprint and/or preventing the user from directly touching an ink printing layer on the backside of the front door panel.

[0050] In addition, when the handle portion 22a on the inner door 20 protrudes towards the front, the width of the doorframe 31b of the outer door 30 on one side of the handle portion 22a of the inner door 20 may be reduced to avoid the handle portion 22a of the inner door 20. In this case, the cover portion 33 is disposed to make the handle portion 22a extend into the allowance space at the back of the cover portion 33. On one hand, the handle portion of the inner door can be covered by the cover portion 33, and an appearance is more aesthetical; on the other hand, each border in the doorframe of the outer door can be maintained to be capable of molding by completely using the extrusion process.

[0051] There is a gap between the handle portion 22a of the inner door 20 and the protecting plate 34 in the front-and-rear direction, to prevent space set aside for movement of the handle portion 22a.

[0052] To effectively protect the backside of the front door panel 32, the protecting plate 34 extends from one end to the other end of the cover portion 33 along a length direction of the cover portion 33, that is, the sizes of the cover portion 33 and the protecting plate 34 are basically the same along the length direction. Preferably, the shape and the size of a part of the protecting plate 34 that is adhered to the cover portion 33 are basically the same as those of the front door panel 32 of the outer door 30, to completely cover the rear surface of the cover portion 33.

[0053] To improve strength, the protecting plate 34 is fixed to the doorframe 31b, so that when the user applies force to the protecting plate 34, the force may not completely act on the cover portion 33 and is shared by the doorframe 31b.

[0054] Referring to FIG. 3, the protecting plate 34 includes a fixing edge 34b (outlined in dashed lines in FIG. 3) fixed to the doorframe 31b, and a free end A away from the doorframe 31b and the heat-insulation portion 31. The fixing edge 34b may be sandwiched between the front door panel 32 and the doorframe 31b. This is beneficial to not only improving the strength of the protecting plate 34, but also close attachment between the cover portion 33 and the protecting plate 34.

[0055] In this embodiment, one side of the fixing edge 34b towards the doorframe 31b is provided with a first flange 34c that extends towards the back of the door, and a surface of the doorframe 31b towards the front of the door is provided with a recess 31c for accommodating the first flange 34c.

[0056] As shown in FIG. 4 and FIG. 5, one side of the protecting plate 34 towards the doorframe 31b is provided with a positioning structure in cooperation with the doorframe 31b, and the positioning structure is configured to locate a position of the protecting plate 34 relative to the doorframe 31b in a length direction of the protecting plate 34. The positioning structure may be in multiple forms, for example, it may be a bolt configured to cooperate with a pin hole provided in the doorframe. In this embodiment, the positioning structure includes positioning slots 34a located at two ends of the protecting plate 34 in a length direction, and the positioning slots 34a are clamped with corners 30b located at ends of the doorframe 31b in the length direction.

[0057] During mounting, the first flange 34c is inserted into the corresponding recess 31c of the doorframe 31b first to fix a relative position between the protecting plate 34 and the doorframe 31b, and the positioning slots 34a as the positioning structure are clamped into the corners 30b of the doorframe 31b, then a cover of the front door panel 32 is provided on front surfaces of the doorframe 31b and the protecting plate 34, and the protecting plate 34 is adhered to the front door panel 32 to sandwich the fixing edge 34b between the doorframe 31b and the front door panel 32.

[0058] Referring to FIG. 2 and FIG. 3, along a width direction of the door, the free end A of the protecting plate 34 exceeds out of the cover portion 33. A shape of an exceeding part of the protecting plate 34 that exceeds out of the cover portion 33 may be set according to a requirement of industrial design.

[0059] In this embodiment, the free end A includes a second flange 34d bent backward. This is beneficial to beautifying a boundary curve of the outer door 30 and reducing visible gaps between the outer door 30 and the inner door 20.

[0060] A shape of a cross section of the second flange 34d may be arc, circular, linear and the like.

[0061] In this embodiment, the second flange 34d is in the shape of a sloping surface and slopes along a direction away from the heat-insulation portion 31. That is, an included angle between the second flange 34d and the cover portion 33 is an obtuse angle. In some other embodiments, the second flange 34d may be perpendicular to a plane of the cover portion 33.

[0062] In the foregoing embodiments, the heat-insulation portion 31 of the outer door 30 is formed by using the heat-insulation glass module and a frame thereof. In another embodiment, the heat-insulation portion of the outer door may be formed by using a heat-insulation door body filled with foamed heat-insulation materials, and the front door panel may be closely combined with heat-insulation materials in a foaming process of the heat-insulation door body to form an indivisible part of the heat-insulation door body, or the front door panel may be connected to a front side of the heat-insulation door body after the foaming process of the heat-insulation door body. In the front-and-rear direction, the cover portion exceeds out of the heat-insulation portion, so that projections of the cover portion and the heat-insulation portion do not overlap in the front-and-rear direction.

[0063] The present invention is disclosed as above, but the present invention is not limited thereto. Any person skilled in the art may make various variations and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be subject to the scope defined by the claims.
