[0045] To further understand the purpose, structure, features, and functions of the present application, the following is a detailed description in conjunction with embodiments.

[0046] The refrigeration appliance 1 described in this embodiment may include a refrigerator, a refrigerator, a freezer, etc. For ease of description, in this embodiment, the width direction of the refrigeration appliance 1 is recorded as the x direction, the depth direction of the refrigeration appliance 1 is recorded as the y direction, and the height direction of the refrigeration appliance 1 is recorded as the z direction. In this embodiment, the front and back directions refer to the y direction and the opposite direction thereof, wherein the front refers to the direction facing the user when the refrigeration appliance 1 is in use, and the rear refers to the direction away from the user when the refrigeration appliance 1 is in use. The thickness direction of the door 3 can also be recorded as y. The top refers to the z direction shown in the figure, and the bottom refers to the opposite direction of the z direction shown in the figure. As shown in FIG. Figure 1 As shown, Figure 1 This is a three-dimensional diagram of a refrigeration appliance according to an embodiment of the present application.

[0047] It should be noted that the refrigeration appliance of the present application is Figure 1 A refrigerator is used as an example for illustrative demonstration. In actual application, the solution of this embodiment can also be applied to other types of refrigeration appliances 1, such as a cross-door refrigerator, a French-door refrigerator, or a single-door refrigerator.

[0048] The refrigeration appliance 1 of this embodiment includes a main body 2 and a door 3. The main body 2 defines at least one storage chamber. The door 3 is movably connected to the main body 2 to open and close at least a portion of the storage chamber.

[0049] The main body 2 of this embodiment defines three storage rooms, which are located Figure 1 The freezer compartment on the left is located Figure 1 The refrigerator compartment on the upper right and Figure 1 The cooling appliance 1 of this embodiment includes three doors 3, which are located at Figure 1 The door 3a on the left for opening and closing the freezer compartment is located Figure 1 The door 3b for opening and closing the refrigerator compartment on the upper right side and the door 3b located on the upper right side Figure 1 The door 3c on the lower right side is used to open and close the temperature changing room.

[0050] Please refer to the following Figures 2 to 4 ,in, Figure 2 An exploded perspective view of a door according to an embodiment of the present application; Figure 3 A three-dimensional diagram of a door according to an embodiment of the present application; Figure 4 This is a partial three-dimensional view of a door after being cut open according to an embodiment of the present application; Figure 5 for Figure 4 A magnified view of area B in the middle. Figure 4 and Figure 5 As shown, at least one of the doors 3 of the refrigeration appliance 1 defines a heat-insulating space P, and polyurethane or other heat-insulating materials are foamed and cured in the heat-insulating space P to form a heat-insulating layer of the door 3. Thus, the door 3 has heat-insulating properties.

[0051] Specifically, in one embodiment of the present application, the door 3 includes a door shell 4, an inner liner 5 located at the rear side of the door shell 4, two end caps 6 connected between the door shell 4 and the inner liner 5, a handle 8 located on one side of the door, and an end cap 7 located at one end of the handle 8. The door shell 4, the inner liner 5, the two end caps 6, the handle 8, and the end cap 7 together form the aforementioned insulation space P. Liquid insulation material is filled into the insulation space P, and after foaming and curing, it forms an insulation layer. Figure 4 、 Figure 5 The thermal insulation layer is not shown.

[0052] In this embodiment, the door shell 4 is a metal door shell, which includes a front plate portion 40 defining the front surface of the door 3 and side portions 41 defining at least part of the side surfaces of the door 3. The side portions 41 are formed by bending the edges of the front plate portion 40 toward the rear.

[0053] Door 3 includes a first side 31 and a second side 32 adjacent to each other. Handle 8 is located on first side 31 of door 3. End cap 6, which defines the bottom end surface of door 3, is located on second side 32. In the present embodiment, when door 3 is in use, first side 31 represents the left side of door 3, and second side 32 represents the bottom side. Of course, in other embodiments, the first side may be the right side of the door, and the second side may be the top side of the door. Other combinations of the first and second sides are also possible, and these are not exhaustive.

[0054] The handle 8 of this embodiment extends along part of the length of the door 3 on the first side 31. The length of the handle 8 of this embodiment exceeds half of the length of the door 3 on the first side 31. Figure 2 The side panel 41 includes a notch 410, where the handle is located. An end cap 7, located on the same side as the handle 8 and also on the first side, is disposed between the side panel 41 and the handle 8 to connect the handle 8 to the door housing 4.

[0055] The handle 8 in this embodiment is a metal handle, which may be manufactured by extruding an aluminum alloy, for example.

[0056] Please refer to Figure 4 The handle member 8 includes a handle groove 10 open toward one side 31 of the door 3. The handle groove 10 of this embodiment is open toward the first side 31, and the user's hand can be inserted into the handle groove 10 to operate the handle member 8, thereby opening the door 3.

[0057] The handle member 8 of this embodiment includes a circumferential cavity 81, namely, a first cavity 81. The first cavity 81 extends along the length direction of the handle member 8, and the first cavity 81 extends along the entire length of the handle member 8.

[0058] The handle member 8 further includes a connecting portion located between the first cavity 81 and the handle groove 10 , and the door shell 4 extends around the first cavity 81 to be connected to the connecting portion.

[0059] In this embodiment, the connecting portion includes a slot 82 located between the handle groove 10 and the first cavity 81, and the end of the door shell 4 is inserted into the slot 82 to realize the connection between the door shell 4 and the handle member 8. Moreover, the end of the door shell 4 is hidden inside the handle member 8, which is beneficial for the door 3 to obtain an aesthetic appearance.

[0060] In this embodiment, along the front-back direction of the door 3, i.e., the depth direction y of the refrigeration appliance 1, the handle member 8 includes a front portion 8a located on the front side of the handle groove 10 and a rear portion 8b located on the rear side of the handle groove 10. The first cavity 81 is located on the front side of the handle groove 10. In other words, the first cavity 81 is located in the front portion 8a.

[0061] As Figure 5 shown, the door 3 includes a gripping portion 30 located in front of the handle groove 10 for the user to grip when operating the handle member 8. The gripping portion 30 includes the first cavity 81. The arrangement of the first cavity 81 can significantly enhance the strength of the door 3, especially the strength of the gripping portion 30, and reduce the possibility of the door deforming on the first side 31.

[0062] The first cavity 81 extends along the entire length of the handle groove 10, so that the strength of the entire gripping area of the door 3 can be enhanced.

[0063] As mentioned above, the door shell 4 includes a front plate portion 40 that limits the front surface of the door 3 and a side portion 41 located on the first side 31 of the door 3. As Figure 5 , Figure 10 and Figure 11 shown, the door shell 4 of this embodiment smoothly extends from the front surface of the door to the side surface of the door and forms a part of the gripping portion 30. Thus, the strength of the gripping portion 30 can be further improved because the pulling force received by the gripping portion 30 can be transmitted to the part of the door outside the gripping area through the door shell 4. It can be seen that, as Figure 5 , Figure 10 , Figure 11 shown, the front surface of the gripping portion 30 facing forward and the side surface facing the first side 31 of the door 3 are formed by the door shell 4.

[0064] The door shell 4 includes a first curved surface portion 42 that smoothly transitions from the front side of the door 3 to the first side 31. The first curved surface portion 42 is formed by chamfering the door shell 4.

[0065] The handle 8 includes a second curved surface 85 corresponding to the first curved surface 42. The radius of the first curved surface 42 is smaller than that of the second curved surface 85. This improves the fit between the first curved surface 42 and the second curved surface 85. Even with manufacturing tolerances, the first curved surface 42 can effectively wrap around the outside of the second curved surface 85, preventing excessive gaps or assembly problems. In this embodiment, the radius of the first curved surface 41 is 3.5 mm, and the radius of the second curved surface 85 is 4.0 mm.

[0066] In this embodiment, the second curved surface portion 85 constitutes a portion of the boundary defining the first cavity 81 .

[0067] In this embodiment, the connecting portion, i.e., the slot 82, is disposed near the handle groove 10. The slot 82 is located at the rear of the gripping portion 30. Thus, the connection between the door 4 and the handle 8 is located at the rear, which is beneficial to shielding the connection portion and improving the appearance of the door body.

[0068] The free end of the side portion 41 of the door shell 4 is folded from the first side 31 along the depth direction x of the handle groove 10, which is also the width direction x of the refrigeration appliance 1, thereby forming a first flange 43 that is inserted into the slot 82. In this embodiment, the slot 82 opens toward the first side 31. The orientation of the slot 82 opening is consistent with the orientation of the handle groove 10 opening. The depth of the slot 82 is determined by the dimensions of the first flange 43. To ensure that the portion 43 can be fully accommodated within the slot 82, the depth of the slot 82 is greater than the dimension of the insertion portion 43 along the width direction x of the refrigeration appliance 1. In this embodiment, the dimension of the first flange 43 along the depth direction x of the handle groove 10 is 4 mm. The depth of the slot 82 is 5 mm or approximately 5 mm.

[0069] like Figure 10 and Figure 11 As shown, the slot 82 includes a first slot wall 821 and a second slot wall 822 disposed opposite each other, wherein the first slot wall 821 is closer to the front surface of the door 3 than the second slot wall 822. The first flange 43 is inserted into the slot 82, abutting against the second slot wall 822. Thus, no obvious gap is formed between the side portion 41 of the door shell 4 and the handle member 8.

[0070] Depend on Figure 10 and Figure 11 As shown, the side portion 41 blocks the connection seam between the first flange 43 and the slot 82 in the front-to-back direction y of the door 3. That is, the connection seam between the first flange 43 and the slot 82 is completely invisible when viewed from the front of the door 3. It should be noted that, while there is no gap between the first flange 43 and the slot 82 in this embodiment, a slight connection seam is formed between them in appearance. This connection seam is not visible from the front of the door 3 and is blocked by the side portion 41.

[0071] The door shell 4 of this embodiment is a metal door shell, and the handle member 8 is an aluminum alloy extrusion. Both are metal parts. The front surface and side surfaces of the gripping portion 30 are formed by the door shell 4, and the rear surface of the gripping portion 30 is formed by the handle member 8. Thus, on the one hand, this solution can further improve the strength of the gripping portion 30 and enhance the strength of the entire door body, especially reducing the possibility of deformation in the handle area. When the user touches the gripping portion 30, the front surface, side surfaces, and rear surface of the gripping portion 30 all provide the user with a unified metallic touch, which can improve the user experience when operating the handle.

[0072] In one embodiment of the present application, a refrigeration appliance 1 is provided, which includes a main body 2 and a door 3. The main body 2 defines at least one storage chamber, and the door 3 is movably connected to the main body 2 to open and close at least a part of the storage chamber. The door 3 includes a door shell 4 that defines the front surface of the door and a handle member 8 that extends along one side of the door 3. The handle member 8 includes a handle groove 10 that opens towards one side of the door 3. Among them, the handle member 8 includes a circumferentially closed first cavity 81 and a connecting portion located between the first cavity 82 and the handle groove 10, and the door shell 4 extends around the first cavity 81 to be connected to the connecting portion.

[0073] As Figure 11 and Figure 12 shown, one end of the first cavity 81 is closed by an end cap 6 located on the second side 32. The other end of the first cavity 81 is closed by an end cap 7 located on the same side as the handle member 8. Among them, the end cap 7 includes a boss 74 that fits the contour of the first cavity 81, and the boss 74 can be inserted into the first cavity 81 to close the first cavity 81.

[0074] Next, please refer to Figures 5 to 9 , where Figure 5 is Figure 4 an enlarged view of area B in Figure 6 a perspective view of the handle member of an embodiment of the present application; Figure 7 a perspective view of the end cap of an embodiment of the present application; Figure 8 a partial top view of the end cap of an embodiment of the present application; Figure 9 a top view of the handle member of the first embodiment of the present application.

[0075] In this embodiment, the end cap 6 located on the second side 32 of the door 3 includes a closing structure 60 and a surrounding structure 61. The closing structure 60 closes the end face of the door 3 on the second side 32, and the surrounding structure 61 protrudes from the closing structure 60 towards the heat insulation space P and forms a surrounding wall, so as to be able to form a sealing fit with the door shell 4, the inner liner 5, and the handle member 8 to prevent the liquid heat insulation material from leaking from the heat insulation space P across the surrounding structure.

[0076] The end cover 6 of this embodiment includes a closing portion 62 that closes the handle member 8 at at least one end in the extending direction of the handle member 8 and a fitting structure 63 that cooperates with the handle member 8. The fitting structure 63 protrudes from the closing portion 60 in the extending direction of the handle member 8. In this embodiment, the fitting structure 63 protrudes from the closing portion 62 by at least 10 mm. As Figure 10 and Figure 11 shown, the fitting structure 63 continuously extends along the inner sidewall of the handle member 8 facing the heat insulation space P.

[0077] In this embodiment, the closing portion 62 is a part of the closing structure 60. The closing portion 62 is a part of the closing structure 60 facing the handle member 8, and is used to close the end of the bottom end of the handle member 8. And, as Figure 3 shown, in this embodiment, the closing portion 62 defines the bottom boundary of the handle groove 10 in its extending direction.

[0078] The fitting structure 63 is a part of the surrounding structure 61.

[0079] The fitting structure 63 includes a recessed portion 65 and an inclined portion 66 connected to the recessed portion 65. The inclined portion 66 is connected to one end of the opening 650 of the recessed portion 65 and extends obliquely away from the opening direction of the recessed portion 65. As Figure 8 shown, the straight line 66a where the inclined portion 66 is located passes through the recessed portion 65.

[0080] As Figure 8 shown in the embodiment, the recessed portion 65 forms a generally square open slot.

[0081] The inclined portion 66 is located at the rear side of the recessed portion 65. Moreover, the dimension of the inclined portion 66 in the thickness direction y of the door 3 is smaller than the dimension of the recessed portion 65 in the thickness direction y of the door 3.

[0082] As Figure 10 and Figure 11 shown, the handle groove 10 is at least partially located in the recessed portion 65.

[0083] As Figure 10 and Figure 11 shown, the fitting structure 63 is adapted to the contour of the handle member 8 facing the heat insulation space P, that is, the two are in shape fit. There can be more choices for the inner contour of the handle member 8 that forms the handle groove 10. The inner contour of the handle member 8 that forms the handle groove 10 can be completely adapted to the contour of the fitting structure 63, can be completely non - adapted, or can be partially adapted. In this way, it is possible for the fitting structure 63 to match a variety of different - shaped handle members 8.

[0084] Among them, Figure 10 is a schematic diagram of the cooperation between the handle member and the end cover in the first embodiment of this application; Figure 11This is a schematic diagram of the cooperation between the handle and the end cover according to the second embodiment of the present application.

[0085] according to Figure 10 and Figure 11 As shown, the present application provides a refrigeration appliance comprising a main body 2 and a door 3. The main body 2 defines at least one storage chamber. The door 3 is movably connected to the main body 2 to open and close at least a portion of the storage chamber. The door 3 comprises a handle 8 and an end cap 6 connected to at least one end of the handle 8 in its extension direction. The handle 8 comprises a handle groove 10 open toward one side of the door 3. The end cap 6 comprises a closing portion 62 and a mating structure 63 mating with the handle 8. The closing portion 62 closes the end of the handle 8 at least at one end in its extension direction. The mating structure 63 protrudes from the closing portion 62 along the extension direction of the handle 8. The mating structure 63 is suitable for matching at least two types of handles 8, wherein the handle grooves 10 of the at least two types of handles 8 have different cross-sections.

[0086] The end cap 6 provided in this solution can be adapted to Figure 10 The handle shown and Figure 11 Thus, the present application provides a refrigeration appliance with a selection of different handles, which increases the diversity of the refrigeration appliance, for example, to meet the needs of different industrial design styles, meet different appearance requirements, or increase brand differentiation, providing users with more choices.

[0087] In the prior art, each handle has a different shape, requiring a corresponding end cap with a new structure. This increases the manufacturer's material and mold costs. The present solution allows the same end cap to be compatible with at least two handles. This allows refrigeration appliances to be equipped with different handles to meet diverse appearance or industrial design requirements without adding new materials or costs.

[0088] Please refer to Figure 9 , Figure 9 for Figure 9 This is a top view of the handle member of the first embodiment of the present application. The cross-section of the handle groove 10 of the handle member 8 of the first embodiment of the present application is square. The handle member 8 has two first walls 801 arranged opposite each other and a second wall 802 located between the two first walls 801. In this embodiment, the two first walls 801 are approximately parallel or nearly parallel. The second wall 802 extends substantially perpendicular to the first walls 801. The first wall 801 extends approximately along the depth direction of the handle groove 10, or in other words, the first wall 801 extends approximately along the width direction x of the refrigeration appliance 1. The second wall 802 extends approximately along the depth direction y of the refrigeration appliance 1.

[0089] The handle member 8 further includes a transition portion 803 connected between the first wall 801 and the second wall 802. The transition portion 803 enables the first wall 801 to smoothly transition to the second wall 802. The two first walls 801, the second wall 802, and the transition portion 803 connected between the first wall and the second wall enclose a handle groove 10, so that the cross-section of the handle groove 10 is generally rectangular.

[0090] Of course, in another embodiment, the first wall 801 is directly connected to the second wall 802, and no transition portion is formed between the first wall 801 and the second wall 802.

[0091] As Figure 8 shown, the shape of the cross-section of the recess 65 of the mating structure 63 is also generally rectangular, just matching the Figure 10 handle groove 10 of the handle member 8 of the first embodiment shown. As Figure 8 shown, the recess 65 includes a first side 601 opposite to the chain and a second side 602 located between the two first sides 601. The first sides 601 are generally parallel or nearly parallel. The second side 602 extends substantially perpendicular to the first sides 601. The first sides 601 extend along the width direction of the refrigeration appliance or along the depth direction x of the handle groove, and the second side 602 extends along the depth direction y of the refrigeration appliance.

[0092] The two first sides 601 and the second side 602 enclose a generally square open groove.

[0093] The recess 65 includes a transition edge 603, and the arrangement of the transition edge 603 enables the first side 601 to smoothly transition to the second side 602.

[0094] The inclined portion 66 and the recess 65 form a spoon shape, and the inclined portion 66 forms a spoon handle shape.

[0095] The mating structure 63 further includes a positioning groove 637 that opens backward.

[0096] The handle member 8 of this embodiment further includes a third wall 804 extending backward at the rear side of the handle groove 10 and a second flanging 805 that is folded back from the end of the third wall 803. The third wall 804 of this embodiment extends backward along the depth direction y of the refrigeration appliance. The second flanging 805 first extends in the depth direction x of the handle groove and then extends along the opposite direction of y. The end 806 of the second flanging 805 extends toward the front surface direction of the door 3.

[0097] As Figure 9As shown, the handle member 8 of the present embodiment further includes a fourth wall 807 connected between the first wall 801 and the third wall 804. The fourth wall 807 extends along the inclined portion 66 when mating with the mating structure 63. Thus, the first wall 801, the third wall 804, and the fourth wall 807 enclose a cavity, which is called the second cavity 83. As introduced before, the handle member 8 includes a first cavity 81 located on the front side of the handle groove 10, and the handle member 8 further includes a second cavity 83 located on the rear side of the handle groove 10. There are cavities in both the front and rear directions of the handle groove 10, which further enhances the strength of the handle member 8 and reduces the possibility of deformation of the door 3 on the first side 31.

[0098] To more smoothly achieve the mating of the handle member 8 and the end cap 6, the handle member of the first embodiment includes a first positioning portion 86. As Figure 9 shown, the handle member of the present embodiment includes two first positioning portions 86 arranged at intervals. The first positioning portion 86 is located on the second wall 802, that is to say, the first positioning portion is located on the bottom wall of the handle groove 10. The bottom wall of the handle groove 10 faces the opening 650 of the handle groove.

[0099] The mating structure 63 includes a first mating portion 636 adapted to the first positioning portion. The first mating portion 636 is located in the recess 65. As Figure 10 shown, in the use state of the door, each first positioning portion 86 extends into the first mating portion 636. It should be noted that the first positioning portion 86 of the present embodiment is a protrusion, and the first mating portion 636 is a groove that mates with the protrusion.

[0100] Through the cooperation of the first positioning portion 86 and the first mating portion 636, the positioning of the handle member 8 and the mating structure 63 of the present embodiment can be achieved.

[0101] The handle member 8 of the present embodiment also cooperates with the positioning groove 637 on the mating structure through the second flanging 805. The positioning groove 637 is a groove recessed towards the heat insulation space, and the end 806 of the second flanging 805 extends into the positioning groove 637 to cooperate with it to prevent the rear side of the handle member 8 from tilting up.

[0102] As Figure 11 shown, as Figure 6 and Figure 7 shown, the end cap 6 of the embodiment can also cooperate with the handle member 8 of the second embodiment. The same structures of the handle member of the second embodiment and the handle member of the first embodiment are numbered the same, and the functions are the same or similar, and will not be repeated here. The difference between the handle member of the second embodiment and the handle member of the first embodiment is that the cross-sections of their handle grooves 10 are different. The cross-section of the handle groove of the handle member 8 of the first embodiment is square. As Figure 11 shown, the cross-section of the handle member 8 of the second embodiment is V-shaped.

[0103] The handle piece of the second embodiment has the same contour facing the heat insulating space P as the handle piece of the first embodiment, so that the end cover 6 can be adapted to the handle piece of the first embodiment and the handle piece of the second embodiment.

[0104] The handle member 8 of the second embodiment includes two opposing first walls 801, a second wall 802 located between the two first walls 801, and a fourth wall 807 parallel to the inclined portion 66. When the handle member 8 is engaged with the mating structure 63, the fourth wall 807 extends in contact with the inclined portion 66. The fourth wall 807 is connected to the second wall 802. Similar to the first handle member, a transition portion 803 is formed between the first wall 801 and the second wall 802.

[0105] The handle member 8 of the second embodiment includes a first cavity 81 located in front of the handle groove 10 and two cavities located between the recessed portion 65 and the handle groove 10, which are defined as a third cavity 84 and a fourth cavity 87. The fourth wall 807 of the handle member 8, the first wall 80, and the second wall 802 form the third cavity 84. The connecting wall 809 connected between the first wall 801 and the second wall 802 near the door shell 4 and the transition portion 803 define the fourth cavity 87. It can be seen that the handle member 8 of the second embodiment includes three cavities, namely the first cavity 81 located in front of the handle groove 10, the third cavity 84 and the fourth cavity 87 located between the handle groove 10 and the recessed portion. The strength of the handle member is also enhanced, which helps to reduce the possibility of deformation of the door 3, especially the possibility of deformation on the first side.

[0106] The handle 8 of this embodiment has a handle groove 10 with a generally V-shaped cross-section. A fourth wall 807, extending obliquely relative to the depth direction x of the handle groove 10, forms the rear wall of the handle groove 10. As a result, the handle groove of this embodiment presents a different appearance and user experience than the handle of the first embodiment.

[0107] When the handle 8 of this embodiment is in use, the fourth wall 807 is in contact with the inclined portion 66. The contour of the handle 8 facing the heat-insulating space P is adapted to the matching structure 63, and the two are matched in shape.

[0108] Please refer to the following Figure 2 、 Figure 3 and Figure 12 、 Figure 13 ,in Figure 12 This is a three-dimensional diagram of an end cap according to another embodiment of the present application. Figure 13 This is a schematic diagram illustrating the mating of an end cap and a handle member in another embodiment of the present application. In this embodiment, the handle member 8 does not extend along the entire length of the first side of the door 3. Instead, the handle member 8 extends along a portion of the length of the first side 31 of the door 3. The door 3 in this embodiment also includes an end cap 7 located on the same side of the handle member 3. Specifically, the end cap 7 is located on the first side 31.

[0109] The end cover 7 includes a closing portion 70 and a fitting structure 71 that cooperates with the handle member 8. Among them, the closing portion 70 closes the end of the handle member 8 at one end in the extending direction. The fitting structure 71 protrudes from the closing portion 70 along the extending direction of the handle member 8. As Figure 2 and Figure 13 shown, the closing portion 70 closes the upper end of the handle member 8, and the closing portion 70 defines the upper boundary of the handle groove 10.

[0110] The fitting structure 71 is configured as a continuously extending surrounding structure that protrudes from the closing portion 70, and surrounds the end of the handle member 8 on the side facing the heat insulation space P of the handle member 8. The fitting structure 71 includes a recessed portion 72 and an inclined portion 73 connected to the recessed portion 72. The inclined portion 73 is connected to one end of the opening of the recessed portion 72 and extends obliquely away from the opening of the recessed portion 72.

[0111] The end cover 7 of this embodiment includes a boss 74 located on the front side of the recessed portion 72 in the use state of the refrigeration appliance. When the end cover 7 is assembled to one end of the handle member 8, the boss 74 is inserted into the first cavity 81 of the handle member 8 to achieve the positioning of the end cover 7.

[0112] The end cover 7 further includes a slit 75 located between the recessed portion 72 and the boss 74. The slit 75 is opposite to the slot 82 of the handle member 8 in the extending direction of the handle member 8, and the end of the door shell 4 is inserted into the slit 75.

[0113] The end cover 7 of this embodiment is formed by injection molding using a plastic material. In order to reduce the problems of uneven wall thickness or surface defects generated by the boss during the injection molding process, the boss 74 includes a hollow portion 740.

[0114] In order to connect the end cover to the end of the handle member 8, the end cover 7 further includes a connecting portion 78, and the connecting portion 78 is located on the fitting structure 71 and protrudes from the fitting structure 71. Specifically, the connecting portion 78 of this embodiment extends from the recessed portion 72 in a direction away from the closing portion 70. The connecting portion 78 of this embodiment includes two hooks 781, and the hook portions of the two hooks 781 are arranged back to back.

[0115] As Figure 13 shown, the handle member 8 includes two convex ribs 88 extending in parallel, and the two hooks 78 extend between the two convex ribs 88 and are hooked with the two convex ribs 88, thereby restricting the end cover 7 from detaching from the handle member 8 in the extending direction of the handle member 8.

[0116] The above-mentioned end cover 7 can also be connected to one end of the handle member 8 of the aforementioned second embodiment. When the end cover 7 cooperates with the handle member of the second embodiment, the fourth wall 807 abuts against the inclined portion 73.

[0117] Next, please refer to Figures 14 to 16 , in whichFigure 14 The top view of the handle part according to the third embodiment of the present application. Figure 15 The schematic diagram of the cooperation between the handle part and the end cover according to the third embodiment of the present application. Figure 16 The schematic diagram of the cooperation between the handle part and the end cover according to the fourth embodiment of the present application.

[0118] The handle part of the third embodiment is similar in structure to the handle part of the second embodiment. The same structures are numbered the same, and their functions are the same or similar, so they will not be elaborated here. Different from the handle part of the second embodiment, the first positioning part 86 of the handle part of the third embodiment is configured as a positioning groove. As Figure 15 shown, the first matching part 636 of the end cover 6 cooperating with the handle part of the third embodiment corresponding to the first positioning part 86 is configured as a protrusion. During the assembly process of the door 3, the protrusion extends into the positioning groove to achieve the positioning of the handle part.

[0119] The handle part 8 of the third embodiment further includes a second positioning part 89. The second positioning part 89 is located on the fourth wall 807 that extends obliquely. The first matching part 636 cooperating with the first positioning part 86 is located in the recessed part 65, and the second matching part 638 cooperating with the second positioning part 89 is located in the inclined part 66, so as to position the handle part 8 in different areas, with better positioning effect, which is beneficial to the quick connection between the handle part 8 and the end cover 6 and improves the production efficiency of the door.

[0120] Figure 16 The schematic diagram shows the cooperation between the handle part and the end cover according to the fourth embodiment of the present application. The handle part of the fourth embodiment is similar in structure to the handle part of the first embodiment. The same structures are numbered the same, and their functions are the same or similar, so they will not be elaborated here. Different from the handle part of the first embodiment, the first positioning part 86 of the handle part of the fourth embodiment is configured as a groove. As Figure 16 shown, the first matching part 636 of the end cover 6 cooperating with the handle part of the fourth embodiment corresponding to the first positioning part 86 is configured as a protrusion. During the assembly process of the door 3, the protrusion extends into the groove to achieve the positioning of the handle part. This is similar to the first positioning part of the handle part and the first matching part of the end cover in the third embodiment.

[0121] The handle part 8 of the fourth embodiment further includes a second positioning part 89. The first matching part 636 cooperating with the first positioning part 86 is located in the recessed part 65, and the second matching part 638 cooperating with the second positioning part 89 is located in the inclined part 66, so as to achieve better positioning of the handle part 8. This is similar to the second positioning part of the handle part and the second matching part of the end cover in the third embodiment.

[0122] Finally, please refer to Figure 17 , Figure 17 The schematic diagram of the cooperation between the handle part and the end cover according to the fifth embodiment of the present application. Figure 17The difference between the handle member of the fifth embodiment shown and the handle member structure of the first embodiment lies in that the cross-sectional shape of the handle groove 10 matches the shape of the mating structure. The fourth wall 807 extending obliquely and the first wall 801 extending along the width direction x of the refrigeration appliance are connected to form the rear wall of the handle groove 10. The cross-sectional area of the handle groove 10 in this embodiment is larger, thus providing a larger operating space for the user. Especially when the thickness of the door 3 is limited, the handle member of this embodiment can still provide a larger operating space for the user. The cross-section of the handle groove 10 in this embodiment is in the shape of a spoon.

[0123] The above is only a description of several embodiments of this application. Through adjustment and combination, this application can have more embodiments. For example, in Figures 2 to 4 the embodiment shown, the handle member 8 extends along a partial length of the door 3 on the first side 31. One end of the handle member 8 is closed by an end cap 6 located on the second side 32, and the other end is closed by an end cap 7 also located on the first side 31. In another embodiment of this application, the handle member can extend along the entire length of the door 3 on the first side 31, that is, the handle groove 10 runs through the entire first side 31. Both end caps 6 located at the top and bottom of the door include the closing portion 62 and the mating structure 63 as described above, and the mating structure 63 forms a recessed portion 65 and an inclined portion 66.

[0124] In another embodiment, the handle member 8 extends along a partial length of the first side 31 and both ends are closed by the end cap 7.

[0125] In Figures 2 to 4 the embodiment shown, the handle member 8 extends along the height direction z of the door 3. In other embodiments of this application, the handle member can extend along the width direction x of the door. The handle member can be located at the top or bottom of the door in different embodiments.

[0126] For another example, as in Figure 8 、 Figure 10 、 Figure 11 and Figure 15 and Figure 16 the inclined portion 66 shown is straight. In other embodiments, the inclined portion 66 can be curved.

[0127] The foregoing shows the handle members of five embodiments. In other embodiments, the handle member can also be manufactured into other shapes. For example, the handle groove of the handle member is made into an arc shape.

[0128] Combined Figures 1 to 16 with the various embodiments of the individual components described, they can be combined with each other in any given way to achieve the advantages of this application.

[0129] This application has been described with reference to the aforementioned embodiments. However, these embodiments are merely exemplary embodiments of the present application. It should be noted that the disclosed embodiments do not limit the scope of this application. On the contrary, modifications and enhancements made without departing from the spirit and scope of this application are intended to be protected by this patent.
