[0046] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0047] If the description of this invention involves orientation (e.g., up, down, left, right, front, back, outside, inside, etc.), then the orientations involved need to be defined. For example, "To clearly express the positions and directions described in this invention, the end closer to the operator is the proximal end, and the end farther from the operator is the distal end." Or, the paper surface or the depth direction of the refrigerator can be used as a reference. Of course, if the positional relationship between the two is defined by mutual reference in the subsequent description, then this definition is not required.

[0048] like Figure 1-11 As shown, a preferred embodiment of the present invention includes a refrigerator door.

[0049] like Figure 1-2 As shown, a refrigerator door body in this embodiment includes a door outer shell, a pair of door end caps 2, and a door inner liner 3. The door outer shell includes a front panel 1 and two side panels. The front panel 1 is fixedly connected to the side panels. The door end caps are snapped onto the end faces formed by the front panel 1 and the side panels. The door inner liner 3 is fixedly connected to the door end caps 2 and the side panels. That is, the door liner 3 can be snapped onto the frame formed by the door end caps 2 and the side panels to form an accommodating space. During the refrigerator manufacturing process, before the operator snaps the door liner 2 onto the frame formed by the door end caps 2 and the side panels, a foaming agent must first be filled into the accommodating space.

[0050] The door end cover 2 is provided with a first groove 21. The groove 21 and the groove wall adjacent to the accommodating space are provided with a plurality of hooks 212. Due to the limitations of the manufacturing process, during the process of processing the hooks 212 by the mold, the junction of the hooks 212 and the groove wall of the first groove 21 must be provided with a clearance groove 211.

[0051] The panel 1 is snapped into the first groove 21 and fixedly connected to the door end cover 2 via the hook 212. The panel 1 can be snapped into the first groove 21 by directly inserting it into the groove and fixing it to the door end cover 2 via the hook 212. Alternatively, for some concealed door end covers, a first flange 11 perpendicular to the panel 1 can be provided on the panel 1, and the first flange 11 can be inserted into the first groove 21 and fixedly connected to the door end cover 2 via the hook 212. The connection method is not limited here.

[0052] In addition, the door end cover 2 is also provided with a movable sealing part. The design of the sealing part is mainly to solve the problem of foaming agent leakage in the void groove 211 during the foaming process. Specifically:

[0053] Before the foaming agent in the accommodating space foams, the sealing part is away from the opening of the air-proof groove 211;

[0054] When the foaming agent in the accommodating space foams, the sealing part is subjected to the impact of the foaming agent, thereby abutting against the opening of the anti-foaming groove 211, which can effectively prevent the foaming agent from leaking.

[0055] like Figure 2 As shown, in this embodiment, the two ends of the panel 1 are provided with a first flange 11 perpendicular to the panel 1. The first flange 11 is snapped into the first groove 21 of the door end cover. The door side panel includes a first side panel 12 and a second side panel 13 integrally formed with the panel 1. This design strengthens the sturdiness of the door shell. The ends of the first side panel 12 and the second side panel 13 are snapped into the door end cover 2.

[0056] Furthermore, the door end cover 2 includes: an end plate 22 parallel to the first flange 11, a first groove 21 provided along a long side of the end plate 22 toward the first flange 11, a slot 111 provided on the first flange 11, and a hook 212 engaged in the slot 111.

[0057] In addition, the door end cover 2 also includes a second groove 23 and a third groove 24. The second groove 23 is provided along one short side of the end plate 22 toward the first side plate 12, and the end of the first side plate 12 is engaged in the second groove 23. The third groove 24 is provided along the other short side of the end plate 22 toward the second side plate 13, and the end of the second side plate 13 is engaged in the third groove 24. It can be seen that the entire end cover is mainly engaged with the door shell through the first groove 21, the second groove 23, and the third groove 24. The hook 212 in the first groove 21 and the slot 111 provided on the first flange 11 are the main components that play the role of fastening.

[0058] Furthermore, the door end cover 2 also includes a baffle 25, which is set along the other long side of the end plate 22 toward the opposite door end cover 2. One end of the baffle 25 is connected to the side wall of the second groove 23, and the other end of the baffle 25 is connected to the side wall of the third groove 24. This design is mainly to ensure the stability of the door end cover 2 and the door shell when they are engaged.

[0059] Furthermore, in order to prevent the door end cap 2 from shifting when it is snapped onto the end face of the door shell, the first flange 11 is provided with a guide strip 112, and the first groove 21 is provided with a matching guide groove 213, and the guide strip 112 abuts against the inner wall of the guide groove 213.

[0060] Furthermore, the hook 212 includes a hook body 2121 and a hook seat 2122. The hook seat 2122 is fixedly disposed in the first groove 21 on the groove wall adjacent to the accommodating space. The hook body 2121 and the hook seat 2122 are integrally formed. The hook body 2121 is disposed facing the groove wall of the first groove 21 away from the accommodating space. The hook body 2121 is engaged in the slot 111. The clearance groove 211 is disposed along the intersection line of the hook seat 2122 and the groove wall of the first groove 21 away from the panel 1.

[0061] Furthermore, the groove wall adjacent to the accommodating space of the first groove 21 is also provided with a groove flange 214. The groove flange 214 abuts against the panel 1. The groove flange 214 increases the contact area between the groove wall and the panel 1, thereby reducing the pressure exerted on the groove wall by the panel 1 and the first flange 11, and preventing the groove wall of the first groove 21 near the accommodating space from being damaged by force.

[0062] Furthermore, the sealing part includes multiple sets of baffles 215, which are vertically arranged on the surface of the end plate 22 facing the accommodating space. Two baffles 215 from any one set are disposed outside the groove wall of the clearance groove 211 parallel to the hook 212. The two baffles 215 are perpendicularly connected to the groove flange 214. A flip piece 216 is provided between the two baffles 215, which is perpendicular to the two baffles 215. The flip piece 216 includes a rectangular fixing part and a rectangular flipping part. The lower side of the rectangular fixing part is fixedly connected to the end plate 22, and the upper side of the rectangular fixing part is connected to the lower side of the rectangular flipping part.

[0063] Before the foaming agent in the accommodating space foams, the rectangular flipped part is away from the opening of the anti-cavity groove 211;

[0064] When the foaming agent in the accommodating space foams, the rectangular flipping part is pushed by the foaming agent and thus abuts against the opening of the cavity groove 211.

[0065] Furthermore, to prevent foaming agent leakage at the connection between the door end cover 2 and the first side panel 12 and at the connection between the door end cover 2 and the second side panel 13, the refrigerator door also includes a sealing element, which covers the connection between the first side panel 12 and the door end cover 2 and the connection between the second side panel 13 and the door end cover 2.

[0066] Specifically, the first side panel 12 includes a second flange 121 parallel to the panel, the second side panel 13 includes a third flange 131 parallel to the panel, and the sealing element includes a first plug 41 and a second plug 42. The first plug 41 covers the junction of the first side panel 12 and the second flange 121 with the door end cover 2, and the second plug 42 covers the junction of the second side panel 13 and the third flange 131 with the door end cover 2.

[0067] Furthermore, the inner door liner 3 is provided with an annular groove 31 along its circumference. The opening of the annular groove 31 faces away from the panel 1. The groove wall of the annular groove 31 is engaged with the frame composed of the baffle 25, the second flange 121, and the third flange 131. The groove wall of the annular groove 31 has strong elasticity. During the processing, the inner door liner 3 is often pressed onto the frame composed of the baffle 25, the second flange 121, and the third flange 131 by a pressing device. The opening of the annular groove 31 faces the refrigerator's refrigeration space. Sealing strips and decorative materials can also be inserted into the opening of the annular groove 31.

[0068] An embodiment of the present invention also provides a refrigerator, which includes the refrigerator door body described above.

[0069] In summary, the refrigerator and its door in this embodiment can bring the following beneficial effects:

[0070] First, the door end cover 2 is provided with a movable sealing part, which can effectively solve the problem of foaming agent leakage in the anti-cavity groove 211 during the foaming process.

[0071] Secondly, the sealing element installed at the connection between the first side plate 12 and the door end cover 2, and the second side plate 13 and the door end cover 2, can prevent the foaming agent from leaking at the connection between the first side plate 12 and the door end cover 2, and the second side plate 13 and the door end cover 2.

[0072] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0073] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
