[0029] Refrigerator door trim strips, installed on the refrigerator door, serve two main functions: first, to provide a seal, ensuring effective cooling within the refrigerator compartments; and second, to act as an adhesive, preventing the refrigerator door from popping open. The base material of the door trim strip is made of at least one of four plastics: ABS, PE, PC, and PP. The plastic is injection molded according to a pre-defined mold structure.

[0030] The present invention provides a refrigerator, which may be various types of refrigerators such as single-door refrigerators, side-by-side refrigerators, French-door refrigerators, and T-door refrigerators. The refrigerator comprises a cabinet and a refrigerator door body 10, wherein the cabinet defines at least one storage space, and the refrigerator door body 10 is configured to open and close at least one of the storage spaces, that is, to expose or close the opening of the storage space. Of course, the refrigerator door body 10 can rotate relative to the cabinet via the hinge portion 420 for opening and closing the cabinet.

[0031] Referring Figure 1 and Figure 2 , the refrigerator door body 10 comprises a door shell 110 and an inner container 120, and a heat insulating material is filled between the door shell 110 and the inner container 120.

[0032] Further, the refrigerator door body 10 further comprises an electrical compartment 130 arranged in the heat insulating material, and the electrical compartment 130 accommodates electronic components for controlling a display screen on a refrigerator door panel and related circuit connections. The electrical compartment 130 is provided with an electrical compartment opening facing the upper end surface of the refrigerator door body 10. Of course, in practical applications of refrigerator door bodies, the refrigerator door body 10 further comprises a cover plate, the cover plate is detachably connected to the door trim assembly 20 for opening and closing the electrical compartment opening, and the cover plate can prevent external dust particles from falling into the electrical compartment 130.

[0033] Referring Figure 3 and Figure 4 , the refrigerator door body 10 further comprises a door trim assembly 20 according to an embodiment of the present invention, which is configured to be assembled on the upper end surface of the refrigerator door body 10, and the door trim assembly 20 comprises:

[0034] a first cavity 30 with an upper opening, wherein an opening is arranged in the first cavity 30, and a water blocking wall 310 is arranged on the outer periphery of the opening. Further, the opening position of the first cavity 30 corresponds to the opening of the electrical compartment 130, and the water blocking wall 310 at the opening position of the first cavity can block accumulated water from flowing into the electrical compartment 130 to affect the operation of electronic components in the electrical compartment 130;

[0035] a second cavity 40 with an upper opening, which is arranged on at least one side of the first cavity 30 in the width direction of the refrigerator door body 10 and communicates with the first cavity 30.

[0036] In one embodiment of the present invention, the door trim assembly 20 further includes a plurality of through holes 410, wherein the through holes 410 penetrate the entire door trim assembly 20, and the heat insulation material is connected to the through holes 410 disposed on the bottom wall of the second cavity 40, so that the heat insulation material inside the refrigerator door 10 is in contact with the outside air, which can ensure the air permeability and flow of the heat insulation material inside the refrigerator door. At the same time, the heat insulation material can also absorb some of the water that flows into the through holes 410.

[0037] In a preferred embodiment of the present invention, the through hole 410 is configured as a circular hole, and four through holes 410 form a rhombus structure. This rhombus structure is arranged in an array on a portion of the bottom wall of the second cavity 40. This arrangement ensures that the through holes 410 allow the insulation material inside the refrigerator door 10 to flow and absorb some accumulated water, while minimizing the area occupied by the through holes 410 on the bottom wall of the second cavity 40. Of course, various variations in the size, shape, or arrangement of the through holes 410 are also within the scope of protection of this invention.

[0038] Furthermore, in one embodiment of the present invention, the second cavity 40 includes a hinge portion 420, which is disposed away from the first cavity 30. The hinge portion 420 is used to connect the refrigerator door 10 and the cabinet, so that the refrigerator door 10 can rotate around the cabinet through the hinge portion 420.

[0039] Specifically, refer to Figure 4 The hinge portion 420 is provided with a water guide groove 421 near the first cavity 30. The water guide groove 421 extends along the thickness direction of the refrigerator door 10. The notch of the water guide groove 421 is provided on the inner side of the refrigerator door. When water flows to the hinge portion 420, it will be concentrated in the water guide groove 421 and flow to the outside of the refrigerator door 10 through the water guide groove 421.

[0040] In one embodiment of the present invention, the width of the water guide groove 421 gradually increases from the outside to the inside of the refrigerator door 10, so as to ensure that the water flows only through the water guide groove 421 to the outside of the refrigerator door and does not flow to other areas of the hinge part 420, thus preventing some parts of the hinge part 420 from rusting.

[0041] In one embodiment of the present invention, the second cavity 40 further includes a transition portion 430, which is disposed between the hinge portion 420 and the first cavity 30 and connects the first cavity 30 and the hinge portion 420. Of course, in the height direction of the refrigerator door 10, the transition portion 430 is higher than the hinge portion 420.

[0042] Furthermore, the bottom wall of the transition portion 430 is inclined, and the portion near the first cavity 30 is higher than the portion of the hinge portion 420, so as to ensure that water accumulated inside the door trim assembly 20 can flow smoothly into the hinge portion 420 and flow to the outside of the refrigerator door 10 through the water guide groove 421.

[0043] In one embodiment of the present invention, the through hole 410 is disposed on the bottom wall of the transition portion 430 of the second cavity. When water accumulates in the door trim assembly 20 and flows through the transition portion 430, the water can be immersed into the through hole 410. The heat insulation material inside the refrigerator door 10 can absorb some of the water, thereby preventing the water from flowing to the outside of the refrigerator door as much as possible.

[0044] It is understood that, in another embodiment of the present invention, the through hole 410 may also be provided on the bottom wall of the water guide groove 421 of the hinge part 420, so that before the accumulated water flows through the water guide groove 421 to the outside of the refrigerator door, it can be immersed in the through hole 410 and absorbed by the heat insulation material.

[0045] In a preferred embodiment of the present invention, the second cavity 40 is disposed on both sides of the refrigerator door 10 in the width direction. When there is water in the door trim assembly 20, the water can be discharged from the first cavity 30 to the left and right sides of the refrigerator door.

[0046] In summary, the present invention provides a door trim assembly, a refrigerator door, and a refrigerator. The first cavity of the door trim assembly has a water-blocking wall around its opening to prevent water from flowing into the electrical compartment of the refrigerator door and affecting the operation of the electronic components inside. The bottom wall of the second cavity of the door trim assembly has multiple through holes, which facilitate the flow of the insulation material inside the refrigerator door and allow some water to be absorbed by the insulation material through the through holes. The hinge portion of the second cavity of the door trim assembly has a water guide groove, which allows water to flow directly into the outside of the refrigerator door to prevent water from flowing to various corners of the door trim assembly and causing rust on the door trim components.
