The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

Terms such as "upper," "above," "lower," "below," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. In this document, "front" when describing the positional relationship of components in the refrigerator door means a direction away from the storage compartment when the refrigerator door is closed, "rear" when the refrigerator door is closed, "up" when the refrigerator door is closed, a direction opposite to gravity when the refrigerator is normally used, and "down" when the refrigerator is normally used, a direction same as gravity, for example, if the device in the drawing is turned over, a unit described as being located "below" or "beneath" other units or features will be located "above" the other units or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Embodiment 1 of the present invention provides an inner door body of a refrigerator door, as shown in fig. 1 to 3, the inner door body 21 includes a door frame 211 and a door liner 212, and the door frame 211 and the door liner 212 both define a door opening 23 for taking and placing articles in a storage compartment, wherein:

an annular V-shaped groove 215 with a V-shaped opening facing the rear side of the inner door body 21 is formed in the inner side of the door frame 211;

the inner door body further includes an auxiliary guide seal 214, and the auxiliary guide seal 214 includes a side wall portion 2141 for abutting to the V-shaped groove 215 along the V-shaped opening and a baffle portion 2142 extending obliquely rearward from a rear edge of the side wall portion 2141;

the inner side of the door liner 212 abuts against the groove formed by the inner side surface of the V-shaped groove 215 facing the door opening 23 and the side wall portion 2141.

As shown in fig. 1-3, door openings 23 are defined in the door frame 211 and the door liner 212, so that a user can access the articles in the storage compartment only by opening the outer door body 22, and the door openings 23 are generally square; it can be understood that four sides of the door frame 211 forming the door opening 23 are inner sides of the door frame 211, and four sides of the periphery of the door frame 211 are outer sides of the door frame 211; the four sides of door liner 212 defining door opening 23 are the inner sides of door liner 212, and the four sides of the periphery of door liner 212 are the outer sides of door liner 212.

As shown in fig. 4 and 5, the V-shaped groove 215 opens toward the rear side, i.e., the V-shaped groove opens toward the storage compartment when the refrigerator door is closed, it can be understood that the two inner sides of the V-shaped groove 215 are necessarily oriented differently, the first inner side 2151 faces toward the door opening 23, and the second inner side 2152 faces away from the door opening 23.

Here, the open-mold foaming process may include the steps of:

step 1: the door frame 211 is put well first, so that the V-shaped opening of the V-shaped groove 215 faces upward, and the annular cavity 213 has an upward opening;

step 2: the side wall portion 2141 of the auxiliary guide seal 214 is inserted into and abuts against the V-shaped groove 215, and since the inner diameter of the V-shaped groove 215 decreases from the opening of the V-shape to the bottom of the V-shaped groove 215, the auxiliary guide seal 214 can be tightly locked in the V-shaped groove 215, and it can be understood that the side wall portion 2141 and the first inner side surface 2151 of the V-shaped groove 215 form a space;

and step 3: injecting a foaming material into the annular cavity 213;

and 4, step 4: when the door liner 212 is clamped with the door frame 211 from top to bottom, the inner side of the door liner 212 needs to be inserted into the space formed by the side wall portion 2141 and the first inner side surface 2151 along the baffle portion 2142, and in the process, the baffle portion 2142 plays a role in guiding, so that the possibility of dislocation between the door liner 212 and the door frame 211 is greatly reduced; it is understood that the inner side of the door liner 212 is also tightly locked in the space formed by the sidewall 2141 and the first inner side 2151; therefore, the stability of the inner door body 21 is enhanced, the gap between the door frame 211 and the door liner 212 is reduced, and the possibility of foaming material overflow is greatly reduced.

Preferably, the blocking portion 2142 of the auxiliary guide seal 214 protrudes from the V-groove 215.

It will be appreciated that in step 3, after the foaming material is injected into the annular cavity 213, the volume of the foaming material will inevitably increase, and there is a risk that the foaming material will overflow to the outside along the second inner side surface 2152 of the V-shaped groove 215. As shown in fig. 4 and 5, the baffle 2142 extends from the V-shaped groove 215, i.e., the length of the second inner side surface 2152 is increased, so that the baffle 2142 can effectively prevent the foam material from overflowing; moreover, the baffle portion 2142 protrudes from the V-shaped groove 215, i.e., the inner diameter of the V-shaped opening of the V-shaped groove is increased, so that, in step 4, it is more convenient to insert the inner side of the door liner 212 into the space formed by the side wall portion 2141 and the first inner side surface 2151 along the baffle portion 2142.

Preferably, a flash well 216 for receiving foaming material is formed between the bottom of the V-groove 215 and the side wall portion 2141. I.e., the bottom of the sidewall portion 2141 does not match the bottom of the V-groove 215, such that a space, i.e., flash well 216, is formed between the bottom of the V-groove 215 and the sidewall portion 2141; therefore, when foaming, the foaming material may flow into the V-groove 215 from the second inner side surface 2152, and at this time, the flash well 216 may receive a portion of the foaming material, thereby further preventing the foaming material from overflowing.

Preferably, the length of the inner side surface of the V-shaped groove 215 facing the door opening 23 is greater than the length of the inner side surface facing away from the door opening 23. Shortening the length of the second inner side 2152 not only reduces manufacturing costs, but also facilitates the flow of foam into the V-groove 215 and thus into the overflow well 216.

Preferably, the V-groove 215 is annular. Here, the V-shaped groove 215 is annular, and the flash well 216 is also annular, so that in the foaming process, as long as the foaming material enters the flash well 216 along a certain point, the foaming material can fill the annular flash well 216, and thus the volume of the foaming material which can be accommodated by the flash well 216 can be greatly increased.

Preferably, the secondary pilot seal 214 is annular and is integrally formed. Here, the side wall portions 2141 of the auxiliary guide seal 214 may be inserted and abutted into the V-groove 215 at one time, facilitating production. As shown in fig. 5, the inner side of the door liner 212 inevitably applies a force to the auxiliary guide seal 214 to face away from the door opening 23, and as shown in fig. 3, both sides of one side of the auxiliary guide seal 214 are connected to one side, so that the sides connected to both sides of the side can provide a pulling force to the side toward the door opening 23, thereby greatly improving the stability of the inner door body 21.

Preferably, the side surface of the side wall portion 2141 facing away from the door opening 23 is provided with a mounting portion 2143 at an interval, and the mounting portion 2143 and the side wall portion 2141 form a receiving groove for receiving the inner side surface of the V-shaped groove 215 facing away from the door opening 23. This receiving groove thus receives the second inner side 2152, thereby allowing the auxiliary guide seal 214 to be better secured to the door frame 211.

Preferably, the auxiliary guide sealing member 214 is annular and integrally formed, and has a mounting portion 2143 at a corner. In the auxiliary guide sealing member 214, two sides form a corner of the auxiliary guide sealing member 214, and the mounting portion 2143 is disposed at the corner, so that the stability of the inner door body 21 can be greatly improved.

Preferably, the outer sides of the door liner 212 and the door frame 211 are provided with mutually cooperating positioning structures. In this way, in step 4, the possibility of the outer sides of the door liner 212 and the door frame 211 being misaligned can be greatly reduced.

Preferably, a hanger is provided in the door opening 23. So that a gallon bottle seat can be arranged in the door opening 23, which is convenient for users to store.

It should be understood that although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description is for clarity only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can also be combined appropriately to form other embodiments understood by those skilled in the art.

The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
