Abstract

The utility model discloses a convex-concave constant temp. freezer gate sealing, which improves the flat type gate sealing of the existing freezer or a constant temp. freezer. The gate sealing is characterized in that the gate sealing strip is arranged on the edge of the body of the freezer; a convex part is arranged on the gate sealing strip; a concave part is arranged on the edge of a corresponded gate frame. When the gate is closed, the convex part is inserted into the concave part; two air chambers can be formed between the convex part and the concave part. The gate sealing with the structure can make the diffusion channel of the cold quantity in the freezer greatly changed. The utility model has the advantages of simple structure and saving energy, and the service life can also be prolonged.

Description

Convex-concave constant temp. freezer gate sealing

The utility model is a kind of convex-concave refrigeration constant temperature chamber door envelope, belongs to the improvement of deep freezer or controlled-temperature cabinet door sealing structure.

The door envelope of existing deep freezer or controlled-temperature cabinet (as domestic refrigerator, refrigerator etc.) mostly is the flat type structure, introduce in " fridge equipment " book of writing according to Xi'an Communications University, " data proves, when (refrigerator) when chamber door is closed, has 70% cold to let out from crack between a door and its frame." the gasket structure that proposes in No. 86203232 " a kind of totally enclosed domestic refrigerator gasket " utility model patents of authorizing in Patent Office of the People's Republic of China on August 5th, 1987; cut off the something lost cold that forms through the metal cabinet heat conduction in the refrigerator; but the contact portion of gasket and casing remains the flat type structure, still unavoidably has certain cold to let out from crack between a door and its frame.

The purpose of this utility model is improved the door envelope of existing flat type structure, and a kind of convex-concave refrigeration constant temperature chamber door envelope is provided, and further reduces the cold that leaks from crack between a door and its frame, to realize energy-conservation and to prolong the life-span that the refrigeration controlled-temperature cabinet uses.

Of the present utility model being characterised in that in the edge of casing is equipped with gasket, on gasket, has jut, on doorframe cooresponding edge, has depressed part with it, jut when door is closed on the gasket embeds the depressed part on the doorframe, the door sealing structure of forming convex-concave improves thermal and insulating performance.

Accompanying drawing 1 is the structural representation of a kind of embodiment of the utility model.Among the figure: 1 casing, 2 adiabatic layers, 3 gaskets, 4 magnetic adhesive tape, 5,6 juts, 7 depressed parts.Accompanying drawing 2 is door constitutions diagram when closing.

Below in conjunction with accompanying drawing the utility model is further described.

With reference to Fig. 1, the utility model is improved the shape of gasket (3) and magnetic adhesive tape (4), and existing magnetic adhesive tape is prolonged jut of certain size formation, and (6) ， And are retrofitted in gasket the edge of casing (1).Simultaneously will be cooresponding with it shape of door (5) also improved, on the doorframe edge, form a depressed part (7).

If door is non-magnetic material formations such as plastics, can be at the bottom of depressed part embedded with metal sheet (8), to guarantee a door tight closure.

State when door is closed as shown in Figure 2, at this moment, the bottom closed contact of the depressed part on the end face of gasket jut 9 and the door, its shape and size should guarantee to form two air chambers (10,11) between jut and depressed part.At this moment, bigger variation takes place in the diffusion channel of the cold in deep freezer or the controlled-temperature cabinet, and as can be seen from Figure 2, cold will be through four points that turn round, four reflect heat faces and two air chambers from the leakage of crack between a door and its frame.Therefore, this convex-concave door sealing structure obviously weakens cold than the heat diffusion ability of existing flat type structure door envelope under equal temperature difference situation.Use the deep freezer of this structure door envelope or the heat insulating effect of controlled-temperature cabinet obviously to improve, but can prolong ， And saves energy in its service life, food fresh keeping is stored also will bring good effect.

This door sealing structure is simple, implements easily applied range.

Claims

1, a kind of convex-concave refrigeration constant temperature chamber door envelope, it is improvement to existing deep freezer or controlled-temperature cabinet gasket, it is characterized in that gasket (3) being housed in the edge of casing (1), on gasket, has jut (6), have depressed part (7) on the edge of its cooresponding door (5) frame, the jut when door is closed on the gasket embeds the depressed part on the doorframe.
