Abstract

The utility model discloses a novel freezer outer box body comprising a front box wall, a left box wall, a rear box wall and a right box wall. The four box walls are formed by one rectangular plate; one of two ends of the rectangular plate is bent back inwardly to from a hook-shaped inward bending portion and the other end is bent back outwardly to form a hook-shaped outward bending portion; and the inward bending portion and the outward bending portion are engaged and locked tightly and are pressed tightly and mutually to form a tight splicing portion. Compared with a box body that is formed by four plates and has four splicing seams according to a traditional technology, the provided novel freezer outer box body enables materials to be saved and the spraying area to be reduced. The process is simplified, the manufacturing time is shortened, and the cost is lowered. The improved splicing portion is pressed tightly to form a sealing state and thus there is no need to paste any sealing materials like an adhesive tape and the like, thereby improving a foaming qualification rate and reducing a rate of repairing and painting repairing. The thickness of the thermal insulating layer of the improved freezer is uniform, thereby improving the heat-insulating property of the product and enhancing the quality and also playing a certain role in realizing low energy efficiency. Besides, because there is no material leakage around the outer box body and the splicing seam is reduced, the appearance quality and the performance of the freezer are obviously improved.

Description

Novel refrigerator outer case

Technical field

the utility model relates to a kind of novel refrigerator outer case.

Background technology

In conventional art; The refrigerator outer case is spliced with single bone mode by four blocks of plates and is processed (shown in accompanying drawing 1 and accompanying drawing 2); The flanging width of single bone is 15 millimeters, and on this this side of 15 millimeters, also need be processed with the buckle that makes it mutual interlocking respectively.Because be single bone splicing, its edge joint position inevitably exists the slit, therefore; After the sheet metal component splicing; In order to prevent that bubble in follow-up foamed process, occurring expects quality problems such as leakage, at the auxiliary material that also must paste adhesive tape and so on the spliced cabinet wall piece, is used to cover and seal the slit of piece; To prevent to steep the leakage of material, after leaking, the bubble material can have a strong impact on outward appearance.By on can know that processing of existing refrigerator outer case and connecting method exist problems, and be many like consumable material, cost is high, technical process is many, the post recruitment is many, production efficiency is low etc.

The utility model content

The purpose of the utility model provides a kind of novel refrigerator outer case that is spliced with two ends button bone by a rectangular slab.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

a kind of novel refrigerator outer case; Comprise the preceding tank wall that surrounds by a rectangular slab, left tank wall, rear box wall and right tank wall; The inside back bending of an end in the two ends of described rectangular slab form hook-shaped in bending part, the outside back bending of the other end form hook-shaped outer bending part, described interior bending part and described outer bending part have contact with stuck mutually and compress each other and form the stitching section of sealing.

preferably, described stitching section is to the inner outstanding fin that is of this outer case, the above the outer surface of corresponding position, stitching section of this outer case is a smooth transition surface.

preferably, described stitching section be positioned at described before on tank wall or the described rear box wall.

The beneficial effect of the utility model is: the casing of four pieces of processing with four blocks of plates in the conventional art is compared, and not only save material, and the area that dusts reduces also; Operation is simplified, and has shortened Production Time, has also saved cost of labor; Stitching section after the improvement is compacted to sealing state, and the encapsulant that therefore need not to tape again and so on has improved the foaming qualification rate, reprocesses touch-up paint and reduces, and reduces and reprocesses cost; The insulation layer thickness uniformity of the refrigerator after the improvement does not have existence originally in the drawback of single bone jointing positions heat-insulation layer attenuation, can improve the product heat-insulating property, improves the quality, and to accomplishing low efficiency certain help is arranged also; Because after outer case did not have the material of leakage and splicing seams minimizing on four sides, product appearance quality and performance significantly improved.

In accompanying drawing: 1, preceding tank wall; 2, left tank wall; 3, rear box wall; 4, right tank wall; 5, interior bending part; 6, outer bending part.

The specific embodiment

Below in conjunction with embodiment shown in the drawings the utility model is done following detailed description the in detail:

are shown in accompanying drawing 3 and accompanying drawing 4; The novel refrigerator outer case of the utility model comprises preceding tank wall 1, left tank wall 2, rear box wall 3 and the right tank wall 4 that is surrounded by a rectangular slab; The inside back bending of an end in the two ends of rectangular slab forms hook-shaped interior bending part 5, the outside back bending of the other end forms hook-shaped outer bending part 6; Interior bending part 5 and outer bending part 6 have contact with stuck mutually and compress each other and form the stitching section of sealing; The stitching section is to the inner outstanding fin that is of this outer case; Promptly inwardly suppress the stitching section, the outer surface that makes corresponding position, stitching section on this outer case exactly is a smooth transition surface, and a kind of preferred form is that this stitching section is positioned on preceding tank wall 1 or the rear box wall 3 (shown in accompanying drawing 3 and the accompanying drawing 4 is that the stitching section is positioned at rear box wall 3).

because single bone of 15 millimeters width has not existed, are just reduced the consumption of steel according to the embodiment shown in accompanying drawing 3 and the accompanying drawing 4 here, the also corresponding minimizing of the area that dusts simultaneously, and material cost reduces; This two procedure of buckle processing on flanging and the flanging also can be cancelled because of not existing of single fracture limit, and the panel beating expense is reduced; After changing the splicing of button bone into, have only one so outer case splicing personnel can reduce because the splicing limit becomes, cost of labor reduces; After the button bone splicing compacting, its piece can be accomplished closely seamless, thus just need not again the encapsulant of Continuous pressing device for stereo-pattern and so on the outer case inwall of splicing back, the while simplified working procedures, personnel reduce, and auxiliary material and cost of labor can reduce; Because edge joint position no longer leaks material, can improve the foaming qualification rate, reprocess touch-up paint and reduce, reduce and reprocess cost; Because cancel on the single fracture limit of 15 millimeters width, make the insulation layer thickness uniformity of refrigerator, there is not existence originally in the drawback of single bone jointing positions heat-insulation layer attenuation, can improve the product heat-insulating property, improve the quality, to accomplishing low efficiency certain help is arranged also; Because after outer case did not have the material of leakage and splicing seams minimizing on four sides, product appearance quality and performance significantly improved.
