[0032] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. Please refer to the accompanying drawings for further details. Figures 1 to 15 The figures shown represent preferred embodiments of the present invention. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent modifications or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0033] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," etc., which indicate orientation or positional relationship, are based on the refrigerator door being in a closed state for seven days of normal use. They are used for the convenience of describing this invention and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In this specification, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Please refer to Figures 1-9 As shown, the present invention provides a refrigerator door 100 that can effectively prevent the door frame from deforming and a refrigerator (not shown) having the refrigerator door 100.

[0036] The refrigerator door 100 includes a door frame 1, a door panel 2 connected to the front side of the door frame 1, and a door liner 3 connected to the rear side of the door frame 1. The door frame 1, the door panel 2, and the door liner 3 form a foaming cavity for foaming, and a heat insulation layer is formed by injecting foaming material into the foaming cavity.

[0037] Furthermore, the door frame 1 includes a frame body 11 and a frame strip 12. The frame strip 12 extends inward from the front periphery of the frame body 11 and is perpendicular to the frame body 11. The frame strip 12 is used to be pasted and fixed to the door panel 2 to fix the door panel 2 to the door frame 1.

[0038] In one specific embodiment, the door frame 1 is integrally injection molded, thereby eliminating seams on the door frame 1, enhancing the stability of the refrigerator door 100, simplifying the assembly process of the refrigerator door 100, and enhancing the appearance of the refrigerator door 100; however, this is not a limitation.

[0039] Specifically, the door frame 1 includes two opposing columns 13 and an end plate 14 connecting the two columns 13.

[0040] The column 13 includes a column body 131 and a column frame strip 132 extending inward from the front periphery of the column body 131 and perpendicular to the column body 131. The end plate 14 includes an end plate body and an end plate frame strip extending inward from the front periphery of the end plate body and perpendicular to the end plate body. It is understood that the column body 131 and the end plate body together form the frame body 11, and the column frame strip 132 and the end plate frame strip together form the frame strip 12.

[0041] Furthermore, the refrigerator door 100 also includes a reinforcing plate 4 disposed on the inner side of the door frame 1 to support the door frame 1, a limiting plate 5 disposed on the door frame 1 to restrict the movement of the reinforcing plate 4 along its length direction, and at least one fixing member 6 fixed to the door frame 1 to fix the reinforcing plate 4; by using the limiting plate 5 and the fixing member 6 to stably fasten the reinforcing plate 4 to the inner side of the door frame 1, the supporting strength of the reinforcing plate 4 on the door frame 1 can be enhanced, preventing the door frame 1 from deforming during the foaming process or preventing the door frame 1 from deforming or twisting under the action of alternating hot and cold.

[0042] Specifically, the reinforcing plate 4 is made of reinforced iron to further enhance the supporting strength of the reinforcing plate 4 for the door frame 1 and prevent the door frame 1 from deforming.

[0043] In one specific embodiment, the reinforcing plate 4 is disposed on the inner side of the column 13 to support the column 13 and prevent the column 13 from deforming. Of course, this is not a limitation.

[0044] The following will be a detailed explanation using the example of the reinforcing plate 4 being located on the inner side of the column 13.

[0045] There are two limiting plates 5, and the two limiting plates 5 are spaced apart on the column 13 along the length direction of the column 13. At the same time, the distance between the two limiting plates 5 is the length of the reinforcing plate 4. Thus, after the reinforcing plate 4 is fixed to the column 13, the two ends of the reinforcing plate 4 abut against the two limiting plates 5 respectively, which can prevent the reinforcing plate 4 from moving along the length direction of the column 13 and enhance the stability of the fixing of the reinforcing plate 4.

[0046] Specifically, the reinforcing plate 4 is integrally formed with the column 13, which simplifies the assembly process of the refrigerator door 100 and reduces costs.

[0047] Please refer to Figure 7As shown, each of the fixing members 6 has a retaining groove 61 for abutting against the reinforcing plate 4. After the fixing member 6 is fixed to the column 13, the retaining groove 61 abuts against the reinforcing plate 4 to prevent the reinforcing plate 4 from shaking and to make the reinforcing plate 4 stick to the column 13, thereby enhancing the stability of the fixing of the reinforcing plate 4 and the supporting strength of the column 13.

[0048] In one specific implementation method, please refer to Figure 8 As shown, the reinforcing plate 4 includes a first plate 41 and a second plate 42 extending in the same direction from opposite ends of the first plate 41 along the length direction. It can enhance the strength of the reinforcing plate 4 and further enhance the supporting strength of the reinforcing plate 4 for the column 13, preventing the column 13 from deforming; of course, it is not limited to this.

[0049] After the reinforcing plate 4 is fixed inside the column 13, the first plate 41 abuts against the column body 131, and the second plate 42 located on the front side abuts against the column frame strip 132.

[0050] In an embodiment where the reinforcing plate 4 includes a first plate 41 and a second plate 42 extending in the same direction from opposite ends of the first plate 41 along its length, the abutment groove 61 is L-shaped. After the fixing member 6 is fixed inside the column 13, one side of the L-shaped abutment groove 61 abuts against the second plate 42 located on the rear side, and the other side abuts against the end of the second plate 42 away from the first plate 41. This prevents the reinforcing plate 4 from shaking and enhances the supporting strength of the reinforcing plate 4 for the column 13.

[0051] Specifically, the fastener 6 is fixedly connected to the column 13 by screws or other fasteners. More specifically, the fastener 6 is fixedly connected to the column frame strip 132, so that there are no fixing marks on the exposed column body 131, enhancing the appearance of the refrigerator door 100.

[0052] In one specific embodiment, each of the reinforcing plates 4 is fixed by three spaced fasteners 6, which enhances the stability of the fixing of the reinforcing plates 4 and enhances the supporting strength of the reinforcing plates 4 for the column 13.

[0053] Furthermore, the door frame 1 corresponding to the reinforcing plate 4 is provided with multiple sets of support ribs 133 spaced apart along its length. That is, the column 13 is provided with multiple sets of support ribs 133. On the one hand, the support ribs 133 can enhance the strength of the column 13 and reduce the deformation of the column 13. On the other hand, after the reinforcing plate 4 is fixed to the column 13, the reinforcing plate 4 is supported on the support ribs 133, and a buffer gap for foaming is formed between the reinforcing plate 4 and the column 13, which increases the flow of foaming material and can further prevent the column 13 from deforming due to foaming.

[0054] Specifically, the support rib 133 is L-shaped to facilitate support of the reinforcing plate 4 from the adjacent sides of the reinforcing plate 4.

[0055] Specifically, from the top or bottom view angle of the reinforcing plate 4, the abutment groove 61 and the support rib 133 form a rectangular structure.

[0056] Furthermore, the refrigerator door 100 also includes a door liner support 7 for supporting the door liner 3. The door liner support 7 is fixed to the rear of the door frame 1 so as to be connected and fixed to the door liner 3.

[0057] Specifically, the door liner support 7 is fixed to the column 13.

[0058] Furthermore, a mating structure 8 is provided between the fixing member 6 and the door liner support member 7 to connect the door liner support member 7 to the door frame 1, simplifying the structure of the refrigerator door 100.

[0059] Specifically, the mating mechanism 8 includes a locking block 81 protruding from the fixing member 6 and a locking groove recessed on the door liner support member 7 that mates with the locking block 81. On the one hand, the mating of the locking block 81 and the locking groove restricts the door liner support member 7 from moving back and forth. On the other hand, one end of the locking block 81 protruding into the locking groove abuts against the locking groove to restrict the door liner support member 7 from moving left and right, thereby connecting the door liner support member 7 to the door frame 1.

[0060] Specifically, the door liner support 7 includes a fixed edge 71 that cooperates with the column body 131, and a connecting edge 72 connected to the rear end of the fixed edge 71 for fixing the door liner 3. The fixed edge 71 and the connecting edge 72 form an L-shaped structure.

[0061] The locking block 81 protrudes from the fixing member 6 toward the fixing edge 71.

[0062] In one specific embodiment, the locking block 81 includes two sub-locking blocks spaced apart in the front-rear direction: a first sub-locking block 811 and a second sub-locking block 812 located behind the first sub-locking block 811. A locking strip 711 protrudes from the fixing edge 71 to cooperate with the first sub-locking block 811. After the door liner support 7 is installed onto the door frame 1, on one hand, the locking strip 711 abuts against the front end face of the first sub-locking block 811, and the connecting edge 72 abuts against the rear end face of the second sub-locking block 812, restricting the door liner support 7 from moving in the front-rear direction; on the other hand, at least one of the first sub-locking block 811 and the second sub-locking block 812 has its end away from the fixing member 6 abut against the fixing edge 71, restricting the door liner support 7 from moving in the left-right direction, thus connecting the door liner support 7 to the door frame 1.

[0063] It is understood that the locking strip 711, the fixing edge 71, and the connecting edge 72 surround and form the locking groove.

[0064] Furthermore, the first sub-block 811 and the engaging strip 711 are provided with mutually guiding inclined surfaces to guide the engaging strip 711 to engage with the front end surface of the first sub-block 811.

[0065] Furthermore, the protruding length of the second sub-block 812 is less than the protruding length of the first sub-block 811. During the process of the door liner support 7 moving forward to engage with the first sub-block 811, the second sub-block 812 will not interfere with the engaging strip 711, thus affecting the installation of the door liner support 7.

[0066] Furthermore, the supporting rib 133 has a gap 1331 between one end of the door liner support 7 and the door frame 1, allowing part of the door liner support 7 to extend into it, thereby enhancing the connection stability of the door liner support 7.

[0067] Specifically, along the length of the door frame 1, each set of support ribs 133 is offset from the fastener 6, and each set of support ribs includes multiple spaced support ribs 133.

[0068] Furthermore, the side of the door liner support 7 that contacts the door frame 1 is provided with a groove 73 for absorbing the foaming material. The groove 73 extends along the length of the door liner support 7. During the foaming process, the groove 73 can absorb the foaming agent that expands and overflows, avoiding the phenomenon of foam leakage and enhancing the appearance of the refrigerator door 100. At the same time, during the foaming process, it is not necessary to attach anti-leakage foam to the door liner support 7 or the corresponding door frame 1, which reduces material and labor costs and improves assembly efficiency.

[0069] In one specific embodiment, the groove 73 includes a first groove 731 and a second groove 732 located behind the first groove 731 and spaced apart from the first groove 731. The width of the first groove 731 is greater than the width of the second groove 732, which increases the flow rate of the foaming material in the first groove 731 and slows down the flow rate of the foaming material. As a result, the amount of foaming material entering the second groove 732 can be reduced, thus avoiding foam leakage.

[0070] Further, please refer to Figures 1-2 , Figures 5-6 as well as Figures 10-15 As shown, the refrigerator door 100 also includes a door end cap 9 installed on the door frame 1.

[0071] In one specific embodiment, the door end cover 9 is installed at the lower end of the door frame 1, that is, the door end cover 9 is installed on the end plate 14 located at the lower end to form a handle for user operation. Of course, this is not a limitation. The door end cover 9 can also be installed on the upper end plate or on the end of the door frame 1 away from the pivot end, as long as it is convenient for the user to operate to open the refrigerator door 100.

[0072] Specifically, the end plate 14 has an installation port 141 for installing the door end cover 9. At the same time, part of the installation port 141 is located on the end plate body, and the other part of the installation port is located on the end plate frame strip. Thus, after the door end cover 9 is installed on the door frame 1, part of the front end face of the door end cover 9 is positioned opposite to the door panel 2.

[0073] Furthermore, the door end cap 9 includes an end cap body 91 fixedly connected to the door frame 1. The end cap body 91 has a first end plate 911 opposite to the door panel 2. The first end plate 911 has a receiving portion 912 for receiving foaming material. After the door end cap 9 is installed on the door frame 1, the receiving portion 912 is exposed towards the door panel 2. Thus, during the foaming process of the refrigerator door 100, the foaming material enters the receiving portion 912 and fills the receiving portion 912. That is, the foaming material fills between the first end plate 911 and the door panel 2, which can bond the first end plate 911 and the door panel 2 together through the foaming material, avoiding delamination and enhancing the appearance of the refrigerator door 100.

[0074] Specifically, the receiving portion 912 refers to the position on the first end plate 911 corresponding to the mounting opening 141. After the door end cover 9 is installed onto the door frame 1, the receiving portion 912 is exposed towards the door panel 2. At the same time, the upper part of the first end plate 911 abuts against the end plate frame strip to prevent the door end cover 9 from becoming skewed.

[0075] Furthermore, the door end cap 9 also includes at least one guide member 92 connected to the end cap body 91 at one end away from the receiving portion 912 and disposed adjacent to the first end plate 911. The at least one guide member 92 is used to guide the foaming material into the receiving portion 912. During the foaming process of the refrigerator door 100, the foaming material can enter the receiving portion 912 under the guidance of the guide member 92, so as to fix the door panel 2 and the first end plate 911 together.

[0076] It is understood that the end of the end cap body 91 that is away from the receiving part 912 refers to the upper end of the end cap body 91 facing the inside of the refrigerator door 100.

[0077] Specifically, each of the guide members 92 includes at least two guide strips 921 fixed at intervals along the length direction of the end cap body 91 on the end cap body 91. The end of the guide strip 921 near the receiving part 912 extends to the first end plate 911, and two adjacent guide strips 921 surround to form a guide groove for guiding the foaming material into the receiving part 912.

[0078] After the door end cap 9 is installed on the door frame 1, part of the structure of the guide member 92 abuts against the end plate frame strip, thereby the guide groove cooperates with the end plate frame strip to guide the foaming material into the receiving part 912.

[0079] In one specific embodiment, the number of guide members 92 is two, and the two guide members 92 are spaced apart along the length direction of the end cap body 91.

[0080] Furthermore, the receiving portion 912 has at least two guide channels 913 extending along the length direction of the first end plate 911. The at least two guide channels 913 are arranged side by side along the height direction of the first end plate 911, and each guide channel 913 has at least one guide port 914 on the side near the guide member 92. The guide ports 914 on adjacent guide channels 913 are staggered. On the one hand, the guide member 92 and the guide channel 913 are connected through the guide port 914, so that the foaming material guided by the guide member 92 can flow into the guide channel 913. At the same time, the guide channel 913 increases the flow path of the foaming material and slows down the flow speed of the foaming material, thereby increasing the area of ​​the receiving portion 912 covered by the foaming material, increasing the bonding area between the door panel 2 and the first end plate 911, and enhancing the connection effect.

[0081] Specifically, the receiving part 912 has a plurality of guide plates 915 protruding from the first end plate 911 and extending toward the door panel. The plurality of guide plates 915 are spaced apart along the height direction of the end cover body 91, and adjacent guide plates 915 surround to form the guide groove 913.

[0082] In one specific embodiment, the plurality of guide plates 915 include a first guide plate 9151 that is configured to cooperate with the end of the door panel 2, and a second guide plate 9152 located on the upper side of the first guide plate 9151 and spaced apart from or spaced apart from the first guide plate 9151.

[0083] It is understood that the first guide plate 9151 mentioned above cooperates with the end of the door panel 2 to prevent spillage; at the same time, a sealing strip can also be provided between the first guide plate 9151 and the end of the door panel 2 to further prevent spillage and enhance the appearance of the refrigerator door 100.

[0084] Meanwhile, the aforementioned guide port 914 is provided on the second guide plate 9152 so that the uppermost guide groove 913 is connected to the guide member 92. At the same time, the adjacent guide grooves 913 are interconnected, and the guide ports 914 on the adjacent second guide plates 9152 are staggered to facilitate increasing the flow of foaming material and slowing down the flow speed of foaming material.

[0085] Meanwhile, the second guide plate 9152, which is close to the guide member 92, is located on the first end plate 911 at a position corresponding to the edge of the mounting port 141 on the edge strip of the end plate. Thus, the second guide plate 9152 and the first guide plate 9151 surround and form the receiving part 912, increasing the area of ​​the receiving part 912 and increasing the connection area between the door panel 2 and the first end plate 911.

[0086] Furthermore, the flow port on the flow channel 913 near the guide member 92 is misaligned with at least one guide member 92, that is, the flow port on the second flow plate 9152 near the guide member 92 is misaligned with at least one guide member 92, so as to increase the flow of the foaming material and slow down the flow speed of the foaming material.

[0087] Furthermore, along the flow direction corresponding to the height of the foam material and the first end plate 911, that is, along the top-down direction, the number of guide ports 914 on adjacent guide grooves 913 decreases, that is, the number of guide ports 914 on adjacent second guide plates 9152 decreases, and the distribution of the guide ports 914 is in a clustered shape towards the center, so that each guide groove 913 can be effectively filled with foam material, that is, the receiving part 912 can be filled with foam material, so that the first end plate 911 and the door panel 2 can be seamlessly bonded together by the foam material, avoiding delamination.

[0088] Furthermore, the door end cap 9 also includes a snap-fit ​​part 93 connected to the end cap body 91 for snap-fit ​​connection with the door panel 2. Correspondingly, the door panel 2 is provided with a snap fastener 21 protruding toward the end cap body 91. After the door panel 2 and the door end cap 9 are installed on the door frame 1, the snap fastener 21 snaps into the snap-fit ​​part 93 to enhance the connection strength between the door end cap 9 and the door panel 2.

[0089] In one specific embodiment, the engaging part 93 is provided on the guide member 92, and the end plate frame strip is provided with a through groove 211 for the buckle 21 to pass through. When the door panel 2 is installed, the buckle 21 passes through the through groove 211 and engages with the engaging part 93, thereby enhancing the connection stability between the door panel 2, the door frame 1 and the door end cover 9.

[0090] Furthermore, the end cover body 91 also includes a second end plate 916 that surrounds the first end plate 911 to form a handle cavity. The end face of the second end plate 916 that contacts the door frame 1 is provided with an overflow groove 9161 for absorbing foaming material. During the foaming process, the overflow groove 9161 can absorb the foaming agent that expands and overflows, avoiding the phenomenon of foam leakage and enhancing the appearance of the refrigerator door 100. At the same time, during the foaming process, it is not necessary to attach anti-leakage foam to the second end plate 916 or the door frame 1, which reduces material costs and labor costs and improves assembly efficiency.

[0091] In summary, the refrigerator door 100 of the present invention uses a limiting plate 5 and a fixing member 6 to stably fasten the reinforcing plate 4 to the inner side of the door frame 1, which can enhance the supporting strength of the reinforcing plate 4 to the door frame 1, prevent the door frame 1 from deforming during the foaming process, or prevent the door frame 1 from deforming or twisting under the action of alternating hot and cold.

[0092] 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.

[0093] 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.
