Description

A kind of refrigerator

Technical Field

The utility model relates to the technical field of refrigeration, in particular to a refrigerator.

Background

The temperature in the freezing chamber of the refrigerator is generally below-18 ℃, the normal usable environment temperature range is generally 10-43 ℃, namely the temperature difference between the inside and the outside of the refrigerator reaches 28-61 ℃. Under the condition that the hinge is fixed from top to bottom at expend with heat and contract with cold effect and door body one side, the door body is middle and the opposite side has the trend of outwards bowing out and warping, causes the door to seal easily at this side and breaks away from the box, leads to air conditioning to leak, influences the normal use of refrigerator. The deformation is greater as the height of the door body is higher.

In order to solve the problem of side deformation of the door body, for a refrigerator with the door body exceeding more than 1.2m, a concave rib is generally added in the middle of the inner container of the door, but the requirement of appearance is limited, the concave rib cannot be too deep, and the deformation prevention effect of the rib of the inner container of the door is limited. Therefore, some products can also add reinforcing iron on one side or two sides of the door body, the reinforcing iron mostly adopts a U-shaped or straight-line structure, and double-sided adhesive tape is adopted to fix the reinforcing iron in the door shell. Although the rigidity of the U-shaped reinforcing iron is improved compared with that of a straight-line-shaped reinforcing iron structure, the deformation prevention effect of the existing reinforcing iron structure is still general for a high door body (for example, the thickness is higher than 1.5m) or a high-end product door body with the deformation requirement of less than 1 mm. If the deformation-preventing requirement of high-end products is completely met, the thickness of the reinforcing iron is generally increased to 1.5-2mm or a plurality of reinforcing irons are placed, but the material cost is greatly increased, and the weight of the thickened reinforcing iron is increased, so that the double-sided adhesive tape is not favorable for fixation. Once the reinforcing iron falls after die assembly, the deformation prevention effect of the reinforcing iron is ineffective, and a door body is scrapped or a series of adverse effects such as customer complaints and repair after delivery are caused.

Thus, improvements in the prior art are needed.

As shown in fig. 1 to 6, a refrigerator according to a preferred embodiment of the present invention mainly includes a cabinet, a door, and a reinforcing iron 200.

A refrigeration chamber is defined within the tank. The refrigerator body generally comprises an outer shell and an inner container, wherein the inner container is arranged in the outer shell, and an installation space is formed between the inner container and the outer shell and used for installing other part structures of a refrigerator and forming a foaming heat-insulating layer. The interior of the inner container forms the refrigeration chamber (a refrigerating chamber, a temperature changing chamber or a freezing chamber). For example, in the present embodiment, the refrigeration chamber may be a freezer chamber.

One side of the box door is connected with the box body in an openable and closable mode through a hinge assembly and is used for opening and closing the refrigeration cavity. The door mainly comprises a door liner 110, a door shell 120, a first door end cover 130 and a second door end cover 140, wherein the first door end cover 130 and the second door end cover 140 are respectively installed at the top and the bottom of the door liner 110 and the door shell 120, as shown in fig. 1. The door liner 110 is a structure forming an inner layer of the door body and is generally prepared by vacuum forming of ABS or HIPS. The door housing 120 is a structure constituting the front surface of the door body, and is generally made of a metal or glass plate. The first door cover 130 and the second door cover 140 are respectively formed on the upper and lower portions of the door body and are generally made of injection-molded parts.

The reinforcing iron 200 is provided inside the door housing 120, and is made of a magnetic material. Further, the reinforcing iron 200 is made of a metal material. Furthermore, the reinforcing iron 200 is made of cold-rolled Q235 steel, so that the raw material cost is effectively reduced.

The reinforcing iron 200 includes a first reinforcing part 210 and second reinforcing parts 220 symmetrically provided at both sides of the first reinforcing part 210. The second reinforcing part 220 is partially attached to the inner sidewall of the door housing 120, and the first reinforcing part 210 is not attached to the inner sidewall of the door housing 120, so that a filling space F is formed between the first reinforcing part 210 and the inner sidewall of the door housing 120. The first reinforcing part 210 is provided with a feed inlet 230 for allowing the foam to enter the filling space F.

Specifically, referring to fig. 3 to 6, the first reinforcing part 210 includes a first middle section 211 and first side sections 212 disposed at both sides of the first middle section 211. The first middle section 211 and the first side section 212 together form the first reinforcement portion 210 with a U-shaped cross section. The end of the first side segment is connected to the second reinforcement part 220. The second reinforcement part 220 includes a second main section 221 and a second sub-section 222. The second main section 221 and the second sub-section 222 together form the second reinforcing part 220 with an L-shaped cross section, the second main section 221 is connected with the first side section 212, and the second main section 221 is attached to the inner side wall of the door shell. In fig. 6, the first middle section 211, the first side section 212, the second main section 221 and the second sub-section 222 are divided by dotted lines, and actually, the reinforcing iron 200 is an integrally formed part, and the cross section of the reinforcing iron 200 is similar to a W shape after being manufactured.

Further, referring to fig. 5, the feeding hole 230 is disposed on the first middle section 211. Further, the feed inlet 230 has a circular or elliptical hole shape. In the embodiment shown in fig. 5, the feed inlet 230 is in the shape of an elliptical hole.

Further, referring to fig. 5, a plurality of the feed openings 230 are provided at intervals along the length direction of the reinforcing iron 200, so that the foam can more easily and uniformly enter the filling space F.

The above-described arrangement of the feed inlet 230 provides several benefits. Firstly, the foam material is favorably fed into the filling space F; secondly, the weight of the reinforcing iron 200 is reduced; thirdly, the materials punched out when the feed inlet 230 is punched out can be recycled as raw materials of other parts or as waste products, which is beneficial to reducing the cost; fourthly, it is advantageous to reduce the resistance of the reinforcing iron 200 when it is molded, to release the pressure when the reinforcing iron 200 is molded, to ensure that the entire length of the reinforcing iron 200 is conveniently manufactured and no deformation occurs.

Further, referring to fig. 6, the ratio of the length of the second sub-section 222 to the length of the first side section 212 is between 0.25 and 0.75.

Further, the length L1 of the first side section 212 is between 10 and 16mm, and the length L2 of the second sub-section 222 is between 5 and 8 mm. Since the first reinforcement portion 210 is not assembled with the door casing 120 and is far from the front surfaces of the door liner 110 and the door casing 120, the height of the middle protrusion can be reasonably increased according to the requirement, and in this embodiment, the length L1 of the first side section 212 is preferably set to be 13.5 mm. The second sub-section 222 is close to the flange (side) and the front of the door housing 120, and is designed to have a short size so as not to affect the entering of the foam, and in this embodiment, the length L2 of the second sub-section 222 is preferably set to be 7 mm.

Further, referring to fig. 4, the second sub-section 222 has a predetermined distance from the inner front wall of the door housing 120. The front wall of the door housing 120 is the front panel of the door housing 120. The arrangement can effectively avoid obstructing the entering and the forming of the foam material.

The preparation of the door needs to adopt a door foaming mold 10, and the door foaming mold 10 mainly comprises an upper mold and a lower mold. Before foaming, the mold is first opened, the door housing 120, the first door cover 130, and the second door cover 140 are set in the lower mold, and the door liner 110 is set in the upper mold. Then, after injecting the foam material into the door housing 120, the door housing is vertically closed, and the foam material is reacted and molded in the door housing 120 to fill the interior of the door.

Since the reinforcing iron 200 of the present application is very rigid, it is generally only necessary to place one on the side opposite the hinge assembly. When only one reinforcing iron 200 is placed on one side of the door shell 120, the magnet 11 is added on the side of the door foaming mold 10 corresponding to the placement of the reinforcing iron 200 during the preparation, and the reinforcing iron 200 is fixed by the magnetic attraction of the magnet 11. Specifically, the distribution of the magnets 11 can be set according to the length and weight interval of the reinforcing iron 200, so that the magnets 11 have enough magnetic attraction to fix the reinforcing iron 200, but the magnetic attraction cannot be too large to influence the taking out of the door after foaming.

To sum up, compared with the prior art, the refrigerator provided by the utility model at least has the following beneficial effects:

the application provides a reinforced iron structure, its cross-section is the W type, has and can form the filling space for the bellied part of door shell lateral wall, and the bellied part has the breach, and the effect is for advancing the bubble material, subtracts heavy and release shaping pressure, makes reinforced iron 200 still strengthen by a wide margin under the thick attenuate condition of material, reduces originally and improves the quality, has solved the problem of freezing big door body deformation. According to the application, the reinforcing iron is designed into a W-shaped structure, the structure of the die becomes complex, the length of the reinforcing iron is less than 2m (completely meeting the height requirements of all refrigerator door bodies) and is added by about 4 thousands compared with that of a U-shaped increasing die, the width of the required material is increased by about 30-50% under the same width, height and wall thickness, the rigidity is 4-8 times of that of the U-shaped reinforcing iron, the thickness of the material can be 1/4-1/8 of the U-shaped structure, and the cost is greatly reduced.

And, the reinforcing iron structure adopts magnetic material preparation, in this application, when foaming, adopts the magnetism cooperation that sets up magnet 11 and reinforcing iron 200 on the mould fixed, need not adopt the fixed reinforcing iron 200 of double faced adhesive tape. Since the foam can enter the filling space F between the reinforcing iron 200 and the door shell 120 during foaming, the reinforcing iron 200 can be fixed after foaming is completed. Compared with the prior art that double faced adhesive tapes are used for fixation, the cost is reduced and the efficiency is improved. And the effective binding face of the reinforcing iron is better as the size is larger, and the binding face of the reinforcing iron and the door shell is better as the size is cleaner, so that the structural design and the material selection of the reinforcing iron are limited. Because the double-sided adhesive tape is adopted for sticking, the oil-free surface of the reinforced iron is required to be enhanced, and the galvanized Q235 is generally adopted. The mode that this application adopted magnet 11 to adsorb is not influenced by the absorption surface has oil, can directly adopt Q235 steel, cancels the galvanizing requirement, and the cost reduces about 3%.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
