Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1, a cold storage door includes: the refrigerator door structure comprises an outer door 1 and an inner door 2 which cover a door opening of a refrigerator, wherein the outer door 1 and the inner door 2 are sequentially arranged from the outer side to the inner side of the refrigerator, the outer door 1 is hinged on an outer door frame, and the outer door 1 can rotate around a vertical shaft to the outer side of the refrigerator to be opened; the inner door 2 comprises an inner door frame 21 and a flap 23, which flap 23 can be rotated about a horizontal axis to open the inner door 2.

Preferably, the turning plate 23 can rotate around the horizontal shaft towards the inner side of the refrigeration house to open the inner door 2, so that the turning plate 23 and the outer door 1 can be prevented from colliding, and meanwhile, the distance between the outer door 1 and the inner door 2 can be set to be small, and the occupied area of the refrigeration house door is saved.

Furthermore, a plurality of feed inlets 22 and a plurality of turning plates 23 are arranged on the inner door frame 21, the turning plates 23 are arranged in one-to-one correspondence with the feed inlets 22, the turning plates 23 cover the feed inlets 22, and the corresponding feed inlets 22 can be opened by rotating one of the turning plates 23. Through a plurality of feed inlets 22 and the setting of turning over board 23, make interior door 2 is divided into a plurality of regions, and during the access material, only need open one of them and turn over board 23, can accomplish through one of them feed inlet 22, with traditional freezer on, thoroughly open the mode of freezer door and compare, this application the freezer door is opening the door area when the access material and is reducing by a wide margin, and cold volume loss also obtains reducing by a wide margin.

As some embodiments of the present application, the flap 23 is rotatably disposed on the throat 22 by a self-closing hinge 24.

Preferably, the self-closing hinge 24 is horizontally arranged on the feed opening 22, and the self-closing hinge 24 can be arranged on the upper side or the lower side of the turning plate 23. In a natural state, the turning plate 23 covers the feeding hole 22 under the action of the self-closing hinge 24, so that the inner door 2 is closed; when feeding is needed, the turning plate 23 is pushed by external force, so that the turning plate 23 rotates around the horizontal shaft to the inner side of the refrigeration house, and the inner door 2 is opened.

As some embodiments of the present application, each of the turning plates 23 is connected with the feed inlet 22 through 2-6 self-closing hinges 24.

Further, set up goods shelves 3 in the freezer, set up a plurality of baffles 4 on the goods shelves 3, through baffle 4 will goods shelves 3 separate into the multilayer.

Furthermore, a tray 5 is arranged on the partition plate 4, and the materials in the cold storage are placed in the tray 5 and then placed on the partition plate 4 in the goods shelf 3 through the tray 5.

Preferably, a plurality of parallel feed inlets 22 are arranged on the inner door frame 21 from top to bottom, and the feed inlets 22 are arranged in one-to-one correspondence with the partition plates 4 in the shelf 3. Through each feed inlet 22, the staff can store the materials in the refrigeration house or take the materials out of the refrigeration house.

Furthermore, electric heating wires are laid around the feed inlet 22, and the feed inlet 22 and the turning plate 23 can be heated by the electric heating wires, so that the feed inlet 22 and the turning plate 23 are prevented from being frozen in the processes of turning and opening, the smooth rotation of the turning plate 23 is influenced, and the turning plate 23 is tightly matched with the feed inlet 22.

When the materials in the cold storage need to be taken out, an operator can push the turning plate 23 inwards after opening the outer door 1, so that the turning plate rotates to open the corresponding feed port 22, then pull out the tray 5 on the goods shelf 3 and take out the materials, and the turning plate 23 can be driven by the self-closing hinge 24 to be closed automatically; when materials need to be stored in the refrigeration house, an operator can firstly place the materials in the tray 5, then open the outer door 1, push the tray 5 to directly push the turning plate 23 inwards, and push the tray 5 into the goods shelf 3 in the refrigeration house, wherein the turning plate 23 can be driven by the self-closing hinge 24 to be closed automatically.

As some embodiments of the present application, the turning plates 23 may be made of a transparent material or an object viewing window covered by a transparent material may be disposed on the turning plates 23, so that an operator may clearly see the material corresponding to each turning plate 23 to rapidly take out the required material.

As some embodiments of the present application, the outer door 1 is made of a polyurethane foam material, so that the outer door 1 has an advantage of good heat insulation effect.

As some embodiments of this application, this application still provides a freezer, the freezer has foretell freezer door, still set up access door 6 on the freezer, when needs overhaul the freezer, the maintainer accessible access door 6 gets into in the freezer.

As some embodiments of the present application, the refrigerator and the refrigerator door can be used for low-temperature storage in the fields of biology, medicine, and the like, in addition to food preservation or refrigeration. For example, in a plasma single-collection station, the plasma needs to be quickly frozen after collection to keep the activity of the plasma, and a quick-freezing refrigeration house needs to keep the low temperature below 45 ℃ below zero. If the door is opened frequently, the temperature of the refrigeration house is influenced, temperature fluctuation is generated, and the plasma activity is not kept favorably. And if the operator frequently enters or exits the refrigeration house, the difficulties of frequently replacing working clothes, sterilizing, working in a low-temperature environment for a long time and the like need to be overcome, and the operation process is very inconvenient. After the refrigeration house is adopted, the temperature in the refrigeration house is kept well, the refrigeration efficiency is improved by more than 30%, and the energy-saving effect is obvious. And the operation is convenient and quick, and the working efficiency of workers can be effectively improved.

In summary, it is easy to find that: the application cold storage door and freezer have following advantage: firstly, when materials are stored and taken out, only one of the turning plates 23 on the outer door 1 and the inner door 2 needs to be opened, the communication area between the inside and the outside of the refrigeration house is small, the loss of cold energy can be effectively reduced, and the fluctuation range of the temperature in the refrigeration house caused by the storage and the taking of the materials is reduced; second, when depositing, getting the thing material, the staff need not get into the freezer and operate in, not only can effectively avoid the injury that low temperature produced to the human body, can also avoid the staff to bring the bacterium into when getting into the freezer, to the adverse effect that the material produced, in addition, need not frequently pass in and out the freezer, the staff just need not frequently change the work clothes for the access material becomes simple, swift, convenient.
