Description

Freezer frame mouth structure and freezer

Technical Field

The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator opening structure and a refrigerator with the same.

Background

At present, the refrigerator opening is generally manufactured by adopting an integral injection molding or split assembly method, but because the refrigerator opening is longer, the error of the refrigerator opening manufactured by integral injection molding is larger, the rejection rate is higher, a mold used for manufacturing the refrigerator opening is generally larger, and the production cost is higher under the influence of the manufacturing process, the environmental temperature and the like.

The existing cabinet opening structure box shell and the cabinet opening and the matching position of the inner container and the cabinet opening are mostly provided with reinforcing ribs, the reinforcing ribs form a fillet structure at four corners at the top part of the cabinet opening, if the sizes of the box shell and the inner container aluminum plate are smaller, the reinforcing ribs are larger in matching error with the cabinet opening, and the installation of the cabinet opening is hard, so that the surface of the cabinet opening is easy to deform, and the influence is attractive. Therefore, the precision of the sizes of the box shell and the inner container is higher in production.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problems, the utility model designs a refrigerator opening structure and a refrigerator applied by the same, and the refrigerator comprises the following specific contents: the utility model provides a freezer cabinet mouth structure, is including the top portion that is the rectangle frame form, be provided with the annular outer strengthening rib with case shell looks adaptation and the annular inner layer strengthening rib with inner bag looks adaptation in the bottom surface of top portion, inside and outside strengthening rib forms 4 fillets respectively, its characterized in that, every in four edges of top portion an opening is seted up in the centre of fillet and is started from the base and upwards extend one section incision.

Preferably, the length of each cut is equal to the height of the rib at the position of the cut.

Preferably, the width of each notch is 1-2 mm.

Preferably, the vertical edges at two ends of each notch are smooth surfaces with flash ground off.

A refrigerator is provided with the refrigerator opening structure.

Compared with the prior art, the utility model has the advantages that:

because the cabinet opening requires smaller size error of the box shell according to the matching size, the precision requirement on equipment is higher, but the existing equipment in most factories cannot meet the error of plus or minus 0.5 percent of the box shell at present, a notch is formed in the middle of the fillet of the reinforcing rib matched with the box shell and the reinforcing rib matched with the inner container, so that products with larger error and smaller size of the box shell can be continuously used in production, the attractiveness is not influenced, and the waste is avoided;

the middle of the reinforcing rib fillet of the existing cabinet opening structure is provided with the small notch, so that the operation is simple, the installation is convenient, the universality is strong, the assembling time of the cabinet opening, the cabinet shell and the inner container is saved, the equipment efficiency is improved, and the productivity is further improved;

with the notch, the foaming agent is more easily distributed on the cabinet opening, and the overall heat insulation performance of the product is improved.

Wherein, 1-cabinet mouth structure; 2-outer layer reinforcing ribs; 3-inner layer reinforcing ribs; 4-rounding off; 5-incision.

Detailed Description

The drawings are for illustration purposes only and are not to be construed as limiting the utility model; for a better understanding of the present embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; for those skilled in the art, some well-known structures in the drawings and descriptions thereof may be omitted; the terms "upper," "lower," "intermediate," "inner," "outer," "bottom," "top," and the like refer to an orientation or positional relationship relative to one another as shown in the drawings, which is for convenience and simplicity of description, and does not indicate or imply that the referenced apparatus or component must have a particular orientation, be constructed in a particular orientation, or be operated in a particular orientation.

The following detailed description is made with reference to the accompanying drawings.

As shown in fig. 1, a freezer opening structure 1 comprises a top portion in a rectangular frame shape, wherein an annular outer reinforcing rib 2 matched with a freezer shell and an annular inner reinforcing rib 3 matched with a liner are arranged on the bottom surface of the top portion, 4 fillets 4 are respectively formed at four corners of the top portion by the inner reinforcing rib and the outer reinforcing rib, and each fillet 4 is provided with a notch 5 with an opening starting from a bottom edge and extending upwards for one section.

The length of each notch 5 is equal to the height of the reinforcing rib at the position of the notch, and the width of the notch is 1-2 mm.

As shown in fig. 2, the notch 5 can be formed by integral injection molding or splicing with the refrigerator opening during production, and the refrigerator opening with the notch 5 can be produced only in a proper mold, so that the vertical edges at two ends of the notch 5 are smooth surfaces with flash removed, and operators cannot be scratched or cut.

Or in the produced cabinet opening structure 1 without the notches 5, the notches 5 with the same height as the positioned reinforcing ribs can be arranged between the rounding off angles 4 of the annular outer layer reinforcing rib 2 matched with the cabinet shell and the annular inner layer reinforcing rib 3 matched with the inner container, and the total number of the notches can be 8.

The operation of forming the notch 5 is simple, only an operator needs to cut one notch 5 in the middle of the rounding angle 4 of the inner and outer reinforcing ribs by using a cutter and the like, and the width of the formed notch 5 is 1-2 mm in order not to affect the appearance.

After the notches 5 are formed, in order to prevent the operator or other persons from being scratched or cut, the vertical edges at both ends of each notch are preferably smooth surfaces with flash removed.

A refrigerator comprises a box shell, an inner container and the refrigerator opening structure. In actual production, because there is the error to exist, the case shell, inner bag and the cabinet mouth structure of production can not match completely, and when the case shell size was little partially, the incision position on the cabinet mouth structure 1 can suitably stretch out and draw back a bit, and it is just easier that the cabinet mouth is got up with case shell and inner bag installation, does not influence pleasing to the eye moreover yet, also makes the easy dispersion of the foaming agent in the heat preservation, more distributes the cabinet mouth more easily, therefore the heat preservation effect is also better.

The utility model is simple to implement, namely, a small notch is arranged in the middle of the fillet of the reinforcing rib of the existing cabinet opening structure, so that the waste caused by industrial production errors can be effectively avoided, the operation is simple, the installation is convenient, and the productivity is further improved.

It is to be understood that the above description is not intended to limit the present invention, and variations, modifications, additions and substitutions that may be made by those skilled in the art without departing from the spirit of the utility model are intended to be included within the scope of the utility model.
