Description

Center sill assembly capable of adapting to size of inner container and refrigerator

Technical Field

The utility model belongs to the technical field of refrigerators, and particularly relates to a middle beam assembly capable of adapting to the size of an inner container and a refrigerator.

A refrigerator is a kind of refrigerating apparatus maintaining a constant low temperature, and is also a home appliance for maintaining food or other articles in a constant low temperature state.

In order to increase the use space in the refrigerator, the prior art has developed a side-by-side combination refrigerator. The side-by-side combination refrigerator adopts a middle beam to wrap and isolate the inner container for foaming, and the middle beam mainly serves as an acting surface for absorbing the seal strip of the refrigerator door. At present, a center sill of the side-by-side combination refrigerator is made of galvanized steel, and an inner container is made of high-gloss HIPS high polymer material. Because the size deviation of about +/-3 mm is influenced by temperature in the forming and manufacturing process of the refrigerator liner, the influence of thermal expansion and cold contraction on the liner is larger, and the influence of thermal expansion and cold contraction on the galvanized steel of B-0.6/DC51D + Z used as the middle beam material is smaller. When the temperature of the inner container is high, the middle beam cannot completely cover the inner container, and the appearance quality of the product is influenced; when the temperature of the inner container is low, the inner container is shrunk, and the middle beam is pressed on the inner container when being longer than the inner container, so that subsequent assembly interference is caused.

In the prior art, the center sill with different sizes is produced according to the temperature change in different seasons so as to adapt to the size change of the liner. However, such a production method of adjusting the processing process according to the change of seasons requires frequent adjustment of the mold, which complicates the manufacturing process. If the adjustment is not timely, the product quality is affected, a large amount of middle beams are scrapped and reworked, and even the foaming box body is scrapped, so that the manufacturing cost is increased.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

Example one

Referring to fig. 1 to 4, in the present embodiment, a center sill assembly adaptable to a size of an inner container includes a center sill 1 and an inner container 2, two folding plates 101 are disposed on an inner surface of the center sill 1, directions of the two folding plates 101 are opposite, the folding plates 101 and the inner surface of the center sill 1 form mounting grooves 102, and the inner container 2 is clamped in the mounting grooves 102 on both sides of the center sill 1. In the actual production process, the materials used for the inner container 2 and the middle beam 1 are different. The inner container 2 is made of a high-gloss HIPS high polymer material, and during molding, size deviation of about +/-3 mm can be generated under the influence of temperature, and the size influence of expansion with heat and contraction with cold on the inner container 2 is large. And the center sill 1 is made of B-0.6/DC51D + Z galvanized steel, and the material is less affected by thermal expansion and cold contraction.

Therefore, as shown in fig. 5-6, when the inner container 2 is heated to a high temperature, the length of the inner container is greater than about 3mm, and the center sill 1 cannot completely cover the inner container 2 when the inner container is manufactured to a standard size. The inner container 2 generates cold contraction effect when the ambient temperature is low, the length of the cold contraction effect is less than about 3mm of the standard size, and the middle beam 1 is manufactured according to the standard size and is longer than the inner container 2, so that assembly interference among the box shell, the inner container and the middle beam is caused, and the quality of the foaming box body is influenced.

To solve this problem, please refer to fig. 5-8, in this embodiment, the length of the center sill 1 is made to adapt to the minimum size of the liner 2 when it is contracted when it is cooled, i.e. the length of the liner 2 is smaller than the standard size by about 3 mm. After the central beam 1 and the liner 2 are clamped through the mounting groove 102, an assembly gap is formed between the upper end of the central beam 1 and the liner 2 (when the liner shrinks to the minimum size in case of cold, the liner is removed). Then, a plurality of filling blocks 3 with the width of 2mm are added in the assembly gap, and finally, the filling blocks 3 are bonded with the center sill 1 through adhesive tapes. In the process, the number of the added filling blocks 3 is determined according to the size of the assembly gap, and the length of the shortage of the middle beam 1 is supplemented by the added filling blocks 3, so that the inner containers 2 with various sizes affected by thermal expansion and cold contraction are wrapped.

Example two

Based on the first embodiment, the present embodiment is different in that:

referring to fig. 9, the center sill assembly of the first embodiment is used in a refrigerator, the refrigerator includes a box body 4, in the first embodiment, a center sill 1 and an inner container 2 are clamped through a mounting groove 102, an assembly gap is generated between the upper end of the center sill 1 and the inner container 2, a plurality of filling blocks 3 with a width of 2mm are added in the assembly gap, and the filling blocks 3 are adhered to the upper end of the center sill 1 through adhesive tapes. And then, putting the assembled center sill 1, the inner container 2 and the filling block 3 into a refrigerator body 4, enabling the center sill 1 to be positioned in a center sill mounting groove on the refrigerator body 4, fixing the center sill 1 and the center sill mounting groove by using bolts in a threaded manner, and foaming. After foaming, the foaming liquid fills the gap between the box body 4 and the center sill assembly to support and seal the inner container 2 and the center sill 1. The gap between the filling block 3 and the middle beam 1 is also filled with foaming liquid, and after the foaming liquid is solidified, the outer leakage part of the fixing adhesive tape between the middle beam and the filling block can be torn off. This assembly process is simple, ensures simultaneously that the size of well roof beam subassembly accords with 2 sizes of inner bag that receive the temperature influence change, guarantees refrigerator product quality, reduces the waste and decreases reduction in production cost.
