Abstract

The utility model discloses a refrigerator with an internal freezing evaporator. The refrigerator comprises a box, a freezing inner container, a foam layer and the freezing evaporator are mounted in the box, the foam layer is wrapped outside the freezing inner container, and the freezing evaporator is arranged between the freezing inner container and the foam layer. The refrigerator breaks through the concept that a direct freezing refrigerator can only function in effective refrigeration by placing a freezing evaporator on the inner surface of a freezing chamber. Experiments prove that the refrigerator can similarly meet the requirement of a refrigerating chamber on refrigeration, micro-frost of the freezing evaporator is realized, and the use space of the freezing chamber is optimized.

Description

The refrigerator of built-in refrigerating evaporator is housed

Technical field

The utility model relates to the refrigeration for refrigerator technology, particularly a kind of arrangement of refrigerator freezing evaporimeter.

Background technology

The refrigerating evaporator of direct cooling refrigerator adopts external threaded pipe type or aluminium sheet aluminium tube type usually.They are placed and are installed in the refrigerating chamber, and the user opens door can see the refrigerating evaporator pipeline.There is following deficiency in this structure: the one, and the easy frosting of refrigerating evaporator, refrigerating evaporator directly freezes in refrigerating chamber, under lower temperature, contained moisture can condense into frost in the refrigerating chamber, partial coverage causes refrigerating evaporator refrigeration variation on refrigerating evaporator, temperature raises; The 2nd, refrigerating evaporator occupies the space of refrigerating chamber, has reduced the capacity that refrigerating chamber is effectively deposited frozen goods, causes the space effectively not utilize.In the prior art, being that the Chinese utility model patent application documents of CN102564014 disclose a kind of defrosting device for refrigerator such as publication number, solving the problem of refrigerating evaporator frosting, is the remedial measure of employing the refrigerating evaporator frosting after basically.Normally naturally place defrost or by defroster is set it is heated defrosting, complex structure not only, and also wayward.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of refrigerator that built-in refrigerating evaporator is housed, and reduces the refrigerating evaporator frosting, simultaneously, has optimized freezing interior space utilization rate.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of refrigerator that built-in refrigerating evaporator is housed, comprise casing, freezing inner bag, foaming layer and refrigerating evaporator are housed in the casing, it is outside that foaming layer is wrapped in freezing inner bag, and described refrigerating evaporator is arranged between freezing inner bag and the foaming layer;

Be compared with existing technology, this programme has overcome direct cooling refrigerator to be only had refrigerating evaporator is placed the refrigerating chamber inner surface, the idea that could effectively freeze, refrigerating evaporator has been installed between freezing inner bag and the foaming layer, experiment showed, that it can satisfy the requirement of refrigerating chamber refrigeration equally, like this, not only realize little frost of refrigerating evaporator, and optimized the usage space of refrigerating chamber.

Described refrigerating evaporator is evenly arranged on the outer surface of freezing inner bag, the outer surface that freezing inner bag is embedded in casing mainly comprises four faces, be the left side, the right side, top and below, refrigerating evaporator can be arranged on one of them, on two, three or four faces, but when refrigerating evaporator is arranged on four faces uniformly, it guarantees that refrigeration is best in the situation of little frost.

Described refrigerating evaporator sticks on the freezing outer surface of liner by heat-conducting glue, refrigerating evaporator has influence on the refrigeration of evaporimeter with the way of contact meeting of freezing outer surface of liner, adopt the heat conduction viscose glue that refrigerating evaporator is connected with freezing outer surface of liner, guaranteed the refrigeration that refrigerating evaporator is good to freezing inner bag.

Described refrigerating evaporator is band-tube type, formed by aluminium sheet and aluminum pipe, aluminum pipe is laid on the aluminium sheet, the concrete form of refrigerating evaporator can have a variety of, and this programme adopts band-tube type, exactly aluminum pipe is fixed on the aluminium sheet, select on the one hand thermal conductivity preferably aluminium as material, the aluminum pipe that will transmit on the other hand refrigerant is installed on the aluminium sheet, has increased refrigeration area, all can optimize refrigeration.

Described aluminum pipe sticks on the aluminium sheet by heat-conducting glue, and aluminum pipe is fixed on the aluminium sheet, with realizing the heat transmission between the aluminium sheet, selects heat-conducting glue to guarantee heat place of production effect, for freezing inner bag refrigeration provides condition.

The specific embodiment

In the present embodiment, the refrigerator that built-in refrigerating evaporator is housed comprises casing, and box house is equipped with freezing inner bag 1, foaming layer and refrigerating evaporator 4.Refrigerating evaporator 4 places between freezing inner bag 1 and the foaming layer, preferably refrigerating evaporator 4 is fixed on the outer surface of freezing inner bag 1, preferably uses heat-conducting glue to bond, and it is not affecting under the refrigeration, and is fixing comparatively firm; Also can pass through other means, such as by elastomer block it being squeezed in the outer surface of freezing inner bag 1, perhaps fixing by screw etc.Above-mentioned refrigerating evaporator 4 preferred band-tube types can be comprised of aluminum pipe 2 and aluminium sheet 3, and this structure can better be laid on refrigerating evaporator 4 outer surface of freezing inner bag 1.Aluminum pipe 2 is fixed on the aluminium sheet 3 by heat-conducting glue, and aluminium sheet 3 evenly is fixed on the outer surface of freezing inner bag 1.In the face of refrigerator, freezing inner bag 1 be inlaid in outer surface in the casing mainly be the left side, the right side, top and below, iff aluminium sheet 3 being laid on one of them or two faces, although can solve the technical problem, refrigeration is good not as whole uniform fold aluminium sheets 2 on four faces.

When refrigeration, refrigerating evaporator 4 is arranged on freezing inner bag 1 outside, increased the usage space of freezing inner bag 1, refrigerating evaporator 4 is positioned at freezing inner bag 1 outside, under this environment, water loading of the air is lower, and refrigerating evaporator 4 is difficult for frosting, and its refrigeration is with that refrigerating evaporator 4 is installed in refrigerating chamber inside is basic identical.
