Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention according to specific situations.

Firstly, the refrigerator floor assembly 100 according to the embodiment of the first aspect of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 , a refrigerator bottom plate assembly 100 according to an embodiment of the present invention includes a bottom plate 10 , a left bracket 20 and a right bracket 30 . Specifically, the bottom plate 10 includes a vertical plate 12 and a first horizontal plate 11 and a second horizontal plate 13 respectively connected to the upper and lower sides of the vertical plate and located on both sides of the vertical plate. The left bracket 20 and the right bracket 30 are respectively arranged at the two ends of the bottom plate 10, and the left bracket 20 and the right bracket 30 are respectively connected with the two ends of the first horizontal plate 11 and the vertical plate 12. Wherein, the base plate 10 is a PVC plate.

According to the refrigerator floor assembly 100 of the embodiment of the present invention, by using PVC board as the bottom board 10, the weight of the bottom board 10 becomes lighter, the assembly process with the refrigerator is better, the production process is simple, the production efficiency is improved, and the cost is reduced; and the PVC board The finished base plate 10 meets the requirements of flame retardancy and has a good appearance. In addition, studies have shown that the polarity of the PVC board and the PU foaming material are similar. When foaming, the adhesion between the two is better, and a firm integrated structure can be formed, which is beneficial to improving the strength of the refrigerator floor assembly 100 .

It should be noted that, in the related art, there are generally two kinds of bottom plates of refrigerators. One is a galvanized steel bottom plate, which has good rigidity and is mainly used for high-end refrigerators or large refrigerators. Because of its high price, it is not used in general refrigerators; the other is an assembly of PP hollow board and galvanized steel plate, which is relatively cheap and mainly It is used in low-end refrigerators and small refrigerators, but it is difficult to meet the new flame retardant requirements of 5VA.

However, according to the refrigerator bottom plate assembly 100 of the embodiment of the present invention, the bottom plate 10 adopts a PVC board, which not only reduces the cost, but also meets the new flame-retardant requirements, and the preparation process of the PVC bottom plate 10 is relatively simple, easy to assemble, and the production efficiency is greatly improved. improve.

Further, according to an embodiment of the present invention, the left bracket 20 and the right bracket 30 are respectively PVC brackets. Therefore, the bottom plate assembly 100 of the refrigerator is made of PVC material as a whole, the overall color is consistent, the appearance is simple and beautiful, and the aesthetics is improved. Moreover, due to the good flame retardancy and low cost of PVC, the refrigerator floor assembly 100 can meet the flame retardancy requirement of 5VA at low cost, and studies have shown that the refrigerator floor assembly 100 made of PVC is similar in polarity to the PU foam material , when foaming, the adhesion between the two is better, the refrigerator floor assembly 100 can form a firm integrated structure with the PU foam material, and while meeting the new flame retardancy requirements, the strength of the refrigerator floor assembly 100 can be improved beneficial effect.

However, in the related art, the left bracket and the right bracket adopt metal brackets, and the adhesion between the metal bracket and the PU foam material is poor, resulting in poor stability of the refrigerator floor assembly. At the same time, when the left bracket 20 and the right bracket 30 of the refrigerator bottom plate assembly 100 according to the embodiment of the present invention adopt PVC brackets, the left bracket 20 and the right bracket 30 can be plastically formed respectively. Compared with the molding method of the metal bracket, the efficiency of blister molding can be increased several times, thereby greatly improving the production efficiency of the left bracket 20 and the right bracket 30 , and thus significantly improving the production efficiency of the refrigerator floor assembly 100 .

According to an embodiment of the present invention, the left bracket 20 and the right bracket 30 are respectively connected to the two ends of the first horizontal plate 11 and the vertical plate 12 through connecting layers. Wherein, the connection layer may be a PVC adhesive layer. That is to say, the bottom plate 10 made of PVC and the left bracket 20 and the right bracket 30 made of PVC are bonded by PVC glue, the bonding performance is good, and the seal is tight, which avoids the sealing caused by poor bonding during the refrigerator manufacturing process. Problems such as poor performance or leaking bubbles.

In the related art, adhesive tapes are used to bond and seal the bottom plate and the left and right brackets, and the adhesiveness and manufacturability are poor. When the bottom plate is a PP hollow board, since the base material of the PP hollow board is non-polar, the adhesion to the PU foam material is poor, so corona treatment is required before bonding, and the preparation process is cumbersome; and the PP hollow board The edge needs to be hemmed to match the left bracket and the right bracket to ensure the tightness of the adhesive tape.

According to the refrigerator bottom plate assembly 100 of the embodiment of the present invention, the whole is made of PVC material, which belongs to polar material, has good adhesion with PU foam material, and does not need corona treatment, thereby effectively reducing the preparation process and improving The production efficiency is improved; and the use of PVC glue has a good bonding effect, and there is no need to set hemming on the edge of the bottom plate 10, so that the structure of the bottom plate 10 is simpler and the preparation is easier.

According to an embodiment of the present invention, the first horizontal plate 11 is arranged parallel to the second horizontal plate 13, and the side of the first horizontal plate 11 away from the vertical plate 12 is provided with an upwardly bent bending portion 111, and the first horizontal plate 11 The plate 11 and the bent portion 111 are provided with a plurality of fitting grooves 112 arranged at intervals. Wherein, the bent portion 111 can be prepared by a hot pressing hemming method.

The first horizontal plate 11 , the vertical plate 12 and the second horizontal plate 13 can be integrally extruded. The integrally extruded structure not only facilitates molding and reduces manufacturing costs, but also ensures the overall structural stability of the base plate 10 and also makes the connection of the entire refrigerator base plate assembly 100 more stable. The extruded bottom plate 10 has a thickness of 0.6-1 mm. Of course, base plates 10 with different thickness specifications can also be prepared according to different needs.

Simultaneously, shapes such as grooves or folded edges can also be plastic-molded on the left bracket 20 or the right bracket 30 according to needs, so as to meet the use requirements of the press chamber parts. For example, hems 40 may be provided on the edges of the left bracket 20 and the right bracket 30 , as shown in FIG. 1 .

Specifically, when preparing the refrigerator bottom plate assembly 100 according to the embodiment of the present invention, the bottom plate 10 made of PVC material can be prepared first by extrusion molding, and then the left bracket 20 and the right bracket 30 made of PVC material can be prepared by blister molding. , and finally use PVC glue to bond the bottom plate 10 with the left bracket 20 and the right bracket 30 together. So far, the refrigerator bottom plate assembly 100 can be roughly prepared.

The refrigerator according to the embodiment of the second aspect of the present invention includes the refrigerator bottom plate assembly 100 of the above embodiment. Since the refrigerator bottom plate assembly 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effect, the refrigerator according to the embodiment of the present invention also has the corresponding technical effect. That is, the preparation cost is low, the preparation process is simple and the flame retardancy requirement is met.
