The invention relates to refrigeration equipment, namely household refrigerators.

The purpose of the invention is to reduce energy consumption and ensure ease of operation of the refrigerator.

FIG. 1 shows schematically the proposed refrigerator, a general view in section; in fig. 2 - flap, two projections; in fig. 3 - L-shaped groove in the side wall of the chamber; Fig 4-valve in the closed position; in fig. 5 - the same, in the open position.

The refrigerator includes a housing 1, a refrigeration unit 2 with an evaporator 3, a door 4 formed by the inner surfaces of the housing 1, a cooled chamber with shelves 5 for products and flaps 6 made of transparent material. Each of the flaps 6 has four cylindrical protrusions 7 at the side ends two in the upper and lower portions which fit into the L-shaped grooves 8, made in the side walls of the chamber between the shelves. This shape of the grooves 8 allows each damper 6 to assume two extreme positions — closed (vertical) and open (horizontal), while due to its movement with an edge ensuring air drag reduction, the change in the position of the damper is not accompanied by vortex formation. In addition, in the raised position, each valve 6 covers the overlying part of the chamber, preventing the convective movement of the cold air flow of the chamber into the open aperture, and the thermal moist air of the environment upward to the evaporator 3.

At the vertices of the corners of the L-image. The snaps of the grooves 8 are made with recesses 9 under the protrusions 7 for fixing the flaps 6 in the extreme positions. In the lower part

Each flap 6 has a handle 10 fixed throughout its entire length, for example, U-shaped, which is designed for conveniently moving the flap 6, as well as for sealing the gap between the open flap 6 and the overlying shelf 5.

The refrigerator works as follows.

In order to get or put the product open the door 4 refrigerators. Through the transparent shutters 6 you can see what exactly is on each of the shelves 5, therefore, to reach the selected product, it is enough to lift the slits 8 up to the shelf 5 only the shutter 6 by means of the handle 10. The cylindrical projections 7 on the shutters 6 in combination with The various grooves 8 allow the rigid shutters 6 to move along the desired path. When the upper cylindrical protrusions 7 reach the extreme rear position, the lower protrusions 7 under the action of

the weights of the flap 6 fall into the recesses of 9 L-shaped grooves 8 and lock the flap 6 in the raised position. To lower the valve 6, it is enough to sweep it by the handle 10, with

In this way, the protrusions 7 protrude from the recesses 9 of the grooves 8 and the flap 6 under its own weight lowers to the closed position. The presence of the grooves 8 recesses 9 also gives the opportunity

the shutter 6 in the closed position rests on all the cup of the ledge 7. The shutters 6, which in the closed position serve as doors, isolate

chambers from the entry of warm and humid air into the atmosphere, in the open position partially or completely (depending on the size of the opening and, accordingly, the dampers) isolate the overlying cold-generating part of the chamber containing the evaporator 3 from the heat leakage from the open opening regardless of as of the 6-way flaps. U-shaped handles 10, made along the entire length of the lower part of the flaps 6, not only provide convenience in opening and closing the flaps 6, they also serve to seal the gaps formed by the open flaps. 6 with overlying shelves 5. At the same time, the total area of the gaps between the closed flaps 6, through which the cold air of the chamber enters the products placed on the inside of the door 4 of the refrigerator, sufficient to cool them.

The use of damper 6 in the proposed cooler leads to a decrease in vortex formation and intensive mixing of the warm air of the environment with the cold air of the chamber. This decrease is due to the movement of the flap by an edge, and not by a plane due to a sharp decrease in the drag of the air against the flap movement. In addition, in the raised position, the flap 6, which is horizontally located and isolates the outer part of the chamber, including the evaporator 3, prevents the camera’s downward flow of cold air, In the open air, and warm moist air of the environment - up, to

evaporator 3. As a result, in the proposed refrigerator, the air exchange between the chamber and the medium is reduced, which leads to a decrease in the power consumed by the cooler, a decrease in the frost formation on the evaporator surface and an increase in the cooling efficiency of the products in the refrigerator compartment.
