Abstract

The utility model discloses a special cold storage internal door for the refrigerating chamber of a refrigerator, comprising an internal door frame [1], a layered small internal door [2], a handle [3] for the layered small internal door, an internal door couplet rotating pin [4] and an internal door frame clamp [5]. The utility model is installed on the refrigerator and can reduce the loss of the refrigerating quantity when the door of the refrigerating chamber of the refrigerator is opened every time so as to achieve the goal that the refrigerator can save power when the refrigerator is used.

Description

Cold storage internal door for refrigerator

The utility model is a kind of auxiliary equipment that power savings is arranged that is exclusively used in household electric refrigerator.

Before the utility model is made, though have which floor storage food shelf in the refrigerating chamber of all kinds of household electric refrigerators, but because a refrigerating chamber has only the total chamber of fan door, therefore, when people need the indoor food of power taking refrigerator cold-storage, and when opening refrigerating chamber chamber door, low-temperature condition in the whole refrigerating chamber is just scurried into and cataclysm by hot-air outdoors at an easy rate, the interior cold air of refrigerating chamber is leaked in a large number, the very fast rising of indoor temperature, thereby, caused refrigerator refrigeration machine work power consumption to increase, power consumption increases.

The purpose of this utility model just is to provide a kind of refrigerator auxiliary equipment, when cold storage chamber of refrigerator chamber door is opened, can reduce the loss of most of indoor cold, realizes power savings.

Existing accompanying drawings structure of the present utility model and operation principle.

The utility model by interior doorframe (1), the little inside door of layering (2), layering little in catch (3), the interior couplet on the door that can rotate flexibly ship and resell on another market (4), interior doorframe folder (5) forms jointly, and forms as a whole.

Fig. 1 is the positive schematic views of the utility model example structure, and wherein the little inside door of layering (2) A is opened, and B, C are closed condition.

To be the interior doorframe (1) of the utility model embodiment and interior doorframe folder (5) thereof store food shelf (6) schematic views when being connected mutually with refrigerating chamber to Fig. 2.

Fig. 3 is that doorframe pressed from both sides (5) in interior doorframe (1) lattice horizontal stripe present position schematic views in the utility model embodiment saw from the negative.

Interior doorframe (1) and the interior couplet on the door ship and resell on another market (4) be to make by metal material, also can be to make of plastics or lucite.

The little inside door of layering (2) is to be made by transparent plastic plate or plastic foil that little doorframe is installed, also can be with transparent poly (methyl methacrylate) plate making.By the interior couplet on the door ship and resell on another market (4) be installed on the interior doorframe (1), all can open arbitrarily flexibly respectively or close.

Interior doorframe (1) and convex protrusions place such as close indoor temperature controller of refrigerator storage of the little inside door of layering (2) and indoor light switch, its shape can be installed as the prerequisite making to adapt to.

Size and its installation site on interior doorframe (2) of catch (3) should be prerequisite not hinder refrigerating chamber chamber door inwall in layering was little.

Interior doorframe folder (5) is by resilient plastic production, also can be to make of resilient metal material or rubber, and it and interior doorframe (1) lattice horizontal stripe closely link together.Because interior doorframe folder (5) has elasticity, so, the utility model in use, just can be easily securely by clip on the indoor storage food shelf limit of refrigerator storage, become refrigerating chamber layering inside door of opening or closing respectively between the door of refrigerating chamber chamber.When needs clean refrigerating chamber, can easily the utility model be removed from refrigerator again.

Fig. 4 is that the utility model embodiment is installed on the refrigerator, after refrigerating chamber chamber door (7) is opened, and the outward appearance schematic views during the little inside door of the utility model layering (2) A breakdown.

When the utility model be installed in refrigerator storage indoor after, when people open refrigerating chamber chamber door, because cold storage internal door has been arranged, the hot-air of outside is just scurried in the refrigerating chamber with convection type suddenly than difficulty, when getting food, then can only open a fan little inside door of layering (2), therefore at every turn, the hot-air of outside can only be fanned the little inside door of layering (2) from this and scurry into sub-fraction, promptly has only the whole refrigerating chamber part of area outwardly.So,, when opening door at every turn and getting food in the refrigerating chamber, just can reduce most loss of refrigeration capacity than the refrigerator that does not have this cold storage internal door.Like this, under the same conditions, refrigerator of the present utility model is installed, just comparable common refrigerator power saving.

Claims
