The embodiment of the utility model provides an inner bag 20 for refrigerator 10. Fig. 1 is a schematic structural view of an inner container 20 for a refrigerator 10 according to an embodiment of the present invention. Fig. 2 is a schematic structural view of the inner container 20 for the refrigerator 10 shown in fig. 1 from another perspective. Fig. 3 is a schematic exploded view of the inner container 20 for the refrigerator 10 shown in fig. 1. Fig. 4 is a schematic exploded view of the inner container 20 for the refrigerator 10 shown in fig. 1 from another perspective. The inner container 20 of the present embodiment is adapted to be assembled to a cabinet of the refrigerator 10 to form a cabinet 110. Unlike the prior art, the liner 20 of the present embodiment is not integrally formed, and includes a liner case 200 and a cooling case 300 which are separately and independently manufactured. The bladder shell 200 and the cooling supply shell 300 are assembled into the inner bladder 20.

Wherein the bladder shell 200 defines a storage space 210 having a forward opening. That is, the bladder shell 200 forms a main body portion for storing articles. The wall of the bladder shell 200 is provided with an assembly opening 220.

The cooling case 300 defines a cooling chamber 310 for accommodating an evaporator. That is, the cooling-supply case 300 forms an attachment portion for mounting the evaporator. And the cooling case 300 can be attached to the bladder case 200 to be assembled into the complete bladder 20. The cooling shell 300 is fixedly assembled with the container shell 200 at the assembling opening 220 and closes the assembling opening 220. That is, when the cooling-supply case 300 is assembled with the container case 200 at the assembly port 220 to form the complete inner container 20, the assembly port 220 is closed by the cooling-supply case 300, which allows the inner container 20 to communicate with the external environment only through the forward opening of the container case 200.

Because the inner bag 20 is including injecing the courage shell 200 of storing space 210 and injecing the cooling shell 300 that is used for holding the evaporimeter to cooling shell 300 can fixed assembly to courage shell 200, consequently, the utility model discloses an inner bag 20 is not integrated into one piece, but the concatenation formula inner bag 20 that is formed by the concatenation combination of a plurality of parts that separate independent manufacturing. Based on the utility model discloses a scheme, at the in-process of shaping courage shell 200, need not to go out cooling shell 300 at the specific region shaping, this is favorable to simplifying the forming process who is used for inner bag 20 of refrigerator 10.

It is worth emphasizing that, by using the above scheme, each part of the inner container 20 can be separately and independently formed, and then the parts are assembled into a whole through fixed connection, which breaks through the thought that the integrally formed inner container is prepared through the plastic suction forming process in the prior art, provides a spliced inner container 20 with a unique structure, provides a solution for reducing the forming difficulty of the inner container 20, manufacturing the special-shaped inner container 20 with an obvious convex structure or a concave structure, simplifying the structure of the forming mold, and improving the flexibility and the versatility of the structure of the inner container 20, and can form a set of brand new manufacturing chain with simple structure of forming equipment, low process difficulty and rich and diverse product structures in the manufacturing process of the inner container 20.

The means for fixedly connecting includes, but is not limited to, any one or a combination of the following: bonding, screw connection, riveting and clamping.

In addition, for the integrally formed liner in the prior art, the specific area of the liner needs to be set to be a protruding structure or a recessed structure due to the fact that the liner needs to be provided with the evaporator and the assembly space needs to be reserved for the evaporator, and the evaporator is large in size, so that the forming process of the liner is very complex. The utility model discloses creatively divide inner bag 20 into the courage shell 200 and the cooling shell 300 that mutually independent made, and make cooling shell 300 inject the cooling chamber 310 that is used for holding the evaporimeter ingeniously, this compares with the current scheme that utilizes polylith panel to splice into inner bag 20's diapire, roof, lateral wall and back of the body wall, not only directly leave out the shaping in shaping cooling chamber on inner bag 20, and left out the concatenation process to polylith panel moreover, only need reserve on courage shell 200 assembly opening 220 and with cooling shell 300 be fixed to assembly opening 220 department can, consequently the utility model provides a scheme is a brand-new scheme that is different from prior art, has a great deal of obvious beneficial effect.

The assembly port 220 is reserved on the liner shell 200, so that a positioning effect can be provided for the fixed assembly of the cooling shell 300, the cooling shell 300 is fixedly assembled with the liner shell 200 at the assembly port 220, and the assembly port 220 can be used as an airflow exchange window between the cooling cavity 310 of the cooling shell 300 and the storage space 210 of the liner shell 200, so that the output efficiency of the heat exchange airflow of the cooling cavity 310 is improved.

The shapes of the bladder housing 200 and the cooling housing 300 may be set according to actual needs, and may be, for example, substantially rectangular box bodies. The cooling-supply case 300 is disposed outside the bladder case 200, which may prevent the cooling-supply case 300 from occupying the storage space 210 defined by the bladder case 200. Of course, in other embodiments, the cooling housing 300 may also be disposed inside the bladder housing 200, for example, when the volume of the cooling housing 300 is relatively small.

The mounting port 220 may be formed in any wall of the bladder shell 200, such as a rear wall, a top wall, a bottom wall, or a side wall. As shown in fig. 3 to 4, the fitting port 220 is opened at the rear wall of the container case 200. Accordingly, the cooling case 300 is provided at the rear side of the cabinet 200, and the evaporator can be disposed at the rear side of the inner container 20, which can make full use of the space in the depth direction of the inner container 20, reducing the lateral and longitudinal dimensions of the refrigerator 10. As shown in fig. 3 to 4, the number of the fitting openings 220 of the present embodiment may be one, and accordingly, the number of the cooling cases 300 is also one.

At this time, different cooling cases 300 may be respectively mounted at different positions of the inner container 200, so that the inner container 20 may be simultaneously mounted with a plurality of evaporators.

Fig. 5 is a schematic structural view of the container case 200 for the inner container 20 of the refrigerator 10 shown in fig. 3. Fig. 6 is a partially enlarged view of a portion a in fig. 5. Fig. 7 is a schematic structural view of a cooling case 300 for the inner container 20 of the refrigerator 10 shown in fig. 3.

In some alternative embodiments, the cooling housing 300 defines a mounting opening 320 that communicates with the cooling chamber 310. The outer periphery of the mounting opening 320 is surrounded by an annular flange 330. That is, the annular flange 330 is formed to extend from the outer periphery of the mounting opening 320 in a direction away from the center of the mounting opening 320. The outer periphery of the mounting opening 220 is surrounded by an annular mounting band 230 which fits against an annular flange 330 for sealing engagement. In this embodiment, the annular fitting band 230 is formed to extend from the outer periphery of the fitting opening 220 toward a direction away from the center of the fitting opening 220. The annular fitting band 230 and the annular flange 330 are in abutting fit to achieve sealing engagement, which means that when the cooling supply shell 300 and the liner shell 200 are fixedly assembled into the complete liner 20, the annular fitting band 230 and the annular flange 330 abut against each other, so that the cooling supply shell 300 and the liner shell 200 are seamlessly connected.

Through set up installing port 320 on cooling shell 300 to utilize the cyclic annular hem 330 that encircles the installing port 320 periphery and encircle cyclic annular assembly area 230 of installing port 220 periphery to cooperate in order to realize sealed joint, be favorable to improving the area of contact at the sealed joint position between cooling shell 300 and the courage shell 200, reduce the assembly degree of difficulty, and improve the leakproofness of the junction between each part of inner bag 20, thereby reduce or avoid leaking out and leaking cold the problem.

In some alternative embodiments, the portions of the annular flange 330 and the annular mounting band 230 that are engaged with each other may be annular flat surfaces, which may suitably simplify the forming process of the annular flange 330 and the annular mounting band 230.

In other alternative embodiments, the annular flange 330 makes a curved contact with the annular mounting band 230. For example, the portions of the annular flange 330 and the annular mounting band 230 that are joined to each other may have curved shapes, i.e., the portions that are joined to each other are not planar. The contact manner of the curved surfaces is not particularly limited as long as the shapes of the curved surfaces which are mutually jointed are matched and the curved surfaces can be mutually abutted.

For example, the joint between the annular flange 330 and the annular mounting band 230 may be curved in an arc shape, one of which may be convex, and the other of which may be concave. For another example, the joint between the annular flange 330 and the annular mounting band 230 may be, but is not limited to, a plurality of non-coplanar planes.

The inventor recognizes that, in the manufacturing process of the refrigerator 10, since the exterior of the inner container 20 needs to be filled with the foaming material, it is critical for the split type inner container 20 to reduce or avoid relative slippage between the components which are split to each other, which is directly related to whether the split type inner container 20 can be used in industry. When the annular flange 330 of the cooling shell 300 is in curved surface contact with the annular assembly band 230 surrounding the periphery of the assembly opening 220, the liner shell 200 and the cooling shell 300 fixed to each other are not easy to slide relatively under the action of external force, which is beneficial to improving the structural stability of the liner 20 in the foaming process, thereby reducing or avoiding the flash phenomenon.

In some alternative embodiments, the annular flange 330 is formed with an annular protrusion that protrudes toward the annular mounting band 230 and surrounds the periphery of the mounting opening 320. The annular protrusion forms a protruding feature on the annular flap 330. And the annular assembling belt 230 is correspondingly provided with an annular concave groove which is concave towards the direction departing from the annular folding edge 330 and surrounds the periphery of the assembling opening 220 so that the annular convex can be clamped into the annular concave groove to realize curved surface contact. The annular recess forms a recessed feature on the annular mounting band 230.

The shape of the mounting opening 320 and the mounting opening 220 can be rectangular, circular, oval or any other shape according to actual needs. As shown in fig. 5-7, the mounting opening 320 and the mounting opening 220 of the present embodiment are each rectangular. Accordingly, the annular flange 330 and the annular fitting band 230 are square annular, respectively. The annular flange 330 may include a flange body and an annular protrusion. The hem body may be an annular plane surrounding the outer periphery of the mounting opening 320, and the annular protrusion may be a square annular protruding area protruding from the hem body toward the annular mounting band 230. Annular mounting band 230 may include a mounting band body and an annular pocket. The assembly belt body may be an annular plane surrounding the periphery of the assembly opening 220, and the annular recess may be a square annular recessed area formed by recessing from the surface of the assembly belt body facing the annular flange 330 toward the direction away from the annular flange 330.

When the annular flange 330 of the cooling shell 300 and the annular assembling belt 230 of the liner shell 200 are matched by adopting a protrusion-recess structure to realize fixing, the annular protrusion on the annular flange 330 is clamped into the annular recess on the annular assembling belt 230, so that quick and accurate positioning can be realized, and the improvement of the assembling precision between the liner shell 200 and the cooling shell 300 is facilitated, and the higher assembling efficiency is ensured.

The annular protrusions and the annular recesses are the same in number and are arranged in a one-to-one correspondence, for example, one or more. When the annular protrusion is snapped into the annular recess, the outer surface of the annular protrusion is surrounded by the inner surface of the annular recess, and a plurality of contact surfaces are formed, portions at the respective contact surfaces abutting each other, respectively.

Adopt above-mentioned structure, when annular protruding card goes into in the annular recess, it is different and towards different contact surfaces to form multiunit position between annular hem 330 and the cyclic annular assembly face to can seal and shutoff in a plurality of different positions and along a plurality of not equidirectional, even if certain contact surface department takes place to seal tight phenomenon, other contact surface departments still can play sealed and shutoff effect, have greatly reduced the risk that sealed tight phenomenon appears in the connection position of each part of inner bag 20.

In some alternative embodiments, as shown in fig. 5-7, the annular protrusion includes a first annular protrusion 331 and a second annular protrusion 332 disposed at a distance from each other, and the second annular protrusion 332 surrounds the first annular protrusion 331 at a circumferential outer side. The annular recesses include a first annular recess 231 and a second annular recess 232 which are arranged at intervals, and the second annular recess 232 surrounds the circumferential outer side of the first annular recess 231. Wherein the first annular recess 231 is fitted corresponding to the first annular protrusion 331, and the second annular recess 232 is fitted corresponding to the second annular protrusion 332.

That is, the first annular projection 331 snaps into the first annular recess 231, and the second annular projection 332 snaps into the second annular recess 232.

Adopt a plurality of annular bulges and a plurality of annular recesses to carry out the one-to-one assembly, can strengthen the accurate nature of location, improve the holistic structural stability of inner bag 20, reduce the probability that takes place relative slip between the different parts, and reduce or avoid leaking out the cold phenomenon of leaking out.

In some further embodiments, the annular flange 330 is further formed with a third annular recess 333 between the first and second annular protrusions 331 and 332. The third annular recess 333 is an annular recessed area surrounding the outer periphery of the first annular protrusion 331, wherein the "concave" is relative to the "convex" of the first and second annular protrusions 331 and 332. The third annular recess 333 may be a planar area on the side of the flange body facing the annular mounting strip 230. Of course, the third annular recess 333 may be a square annular recessed area recessed from the flange body surface toward the annular attachment band 230 surface.

A third annular protrusion 233 is formed on the annular fitting band 230 between the first annular recess 231 and the second annular recess 232. The third annular projection 233 is an annular raised area around the outer periphery of the first annular recess 231, wherein "convex" is referred to herein as "concave" relative to the first and second annular recesses 231, 232. The third annular projection 233 may be a flat area on a side of the mounting strip body facing the annular flange 330. Of course, the third annular projection 233 may be a square annular projection region formed by projecting from the assembly band body toward the annular flange 330 toward one surface of the annular flange 330.

The third annular projection 233 is fitted into the third annular recess 333. That is, when the annular flange 330 of the cooling housing 300 and the annular fitting band 230 of the bladder housing 200 are fitted to each other in a "protrusion-recess" structure to achieve the fixing, the first annular protrusion 331 is fitted into the first annular recess 231, the second annular protrusion 332 is fitted into the second annular recess 232, and at the same time, the third annular protrusion 233 is fitted into the third annular recess 333. That is, the annular flange 330 and the annular mounting band 230 are fused to each other and are integrated using sets of "bump-and-socket" structures.

Based on the above structure, the two independent components of the liner shell 200 and the cooling shell 300 can be integrated through fixing and assembling, and the integrated liner 20 has good structural stability, reduces the risk of flash in the foaming process, and effectively ensures the yield of the refrigerator 10 in the manufacturing process.

In some alternative embodiments, an adhesive material is disposed between the annular flange 330 and the annular mounting band 230 for adhesively securing the annular flange 330 to the annular mounting band 230. The adhesive material may be, for example, polyethylene (PE) with double-sided tape, an epoxy adhesive, a polyvinyl acetate adhesive, a phenol resin adhesive, a polyurethane adhesive, a chloroprene rubber adhesive, an acrylate adhesive, or the like.

Adhesive materials may be provided at respective portions of the annular flange 330 and the annular fitting band 230, which are abutted against or contacted with each other, so as to enhance the adhesive strength between the bladder shell 200 and the cooling case 300, thereby securing the structural stability of the bladder 20. In the practical application process, the bonding material can be attached or coated on each part of the annular folding edge 330, which is abutted against and matched with the annular assembling strip 230, and then the cooling supply shell 300 is adhered to the liner shell 200, so that the fixing and assembling mode is very simple and convenient, the complexity of the assembling process can be greatly reduced, and the assembling efficiency is improved.

In some alternative embodiments, the bladder shell 200 is formed with a front convex annular ridge 250, and the front convex annular ridge 250 protrudes forward from the inner surface of the rear wall of the bladder shell 200 and is raised in an annular shape. For example, the front convex annular ridge 250 may be formed to protrude (or protrude) from a specific annular region of the rear wall of the bladder shell 200 toward the front opening of the bladder 20. As shown in fig. 1, the front convex annular ridge 250 may have a square ring shape.

The mounting opening 220 is located in the annular region of the forward raised annular ridge 250. An annular fitting band 230 surrounding the fitting opening 220 is formed at the rear surface of the front convex annular protuberance 250 so as to fixedly fit the cooling-supply case 300 to the rear side of the bladder case 200.

With the above structure, the partial region of the rear wall of the bladder shell 200 is protruded forward to form the front convex ring-shaped protrusion 250, so that the distance between the cooling chamber 310 of the cooling housing 300 and the storage space 210 of the bladder shell 200 can be shortened to a certain extent, and the rear space of the bladder shell 200 can be fully utilized, and these rear spaces of the bladder shell 200 can also be used for accommodating at least a part of the evaporator, thereby reducing the volume of the cooling housing 300 to a certain extent and reducing the depth dimension of the refrigerator 10.

The front convex annular ridge 250 may be fixedly fitted with the rear wall of the bladder shell 200. In some further embodiments, the forward annular ridge 250 is made of a thermally insulating material that thermally isolates the inner annular region of the forward annular ridge 250 from its peripheral region.
