Fig. 1 shows a refrigerator as an embodiment of a refrigerator 100 with a refrigerator door 106. With the refrigerator door 106, an inner space 102 can be opened and closed again, in which a plurality of shelves 104 are arranged. In the present embodiment, the shelves 104 are stationary in the interior 102. In addition, in the present embodiment, the shelves 104 are made of glass. However, they can also be made of another, optically transparent material, or of a non-transparent material. Refrigerated goods can be stored on the shelves to keep them cool.

The refrigerator is used, for example, for cooling food and includes a refrigerant circuit with an evaporator (not shown), a compressor (not shown), a condenser (not shown) and a throttle body (not shown).

The evaporator is designed as a heat exchanger in which, after expansion, the liquid refrigerant is absorbed by heat from the medium to be cooled, i. Air inside the refrigerator, is evaporated.

The compressor is a mechanically driven component that draws refrigerant vapor from the evaporator and expels it at a higher pressure to the condenser.

The condenser is designed as a heat exchanger in which, after compression, the evaporated refrigerant is released by heat to an external cooling medium, i. the ambient air is liquefied.

The throttle body is a device for the continuous reduction of the pressure by reduction in cross section.

The refrigerant is a fluid used for heat transfer in the cryogenic system which absorbs heat at low temperatures and low pressure of the fluid and releases heat at higher temperature and higher pressure of the fluid, usually including changes in state of the fluid.

Fig. 2 shows that the shelf 104 has two guide rails 204 on two opposite longitudinal sides 208. The guide rails 204 have a U-shaped cross-section in the direction of their longitudinal extent, so that they each have a groove 206 into which the respective longitudinal side edge sections of the shelf 104 are immersed. The guide rails 204 are used for fixed attachment of the shelf 104 in the interior 102 of the refrigerator 100 by being connected to the inner side walls of the refrigerator 100.

On the shelf 104, a tray 200 is arranged. In the present exemplary embodiment, the tray 200 has a peripheral edge 202 and a base 214 bordered by the edge 202, which is designed as a footprint for refrigerated goods to be cooled. The bottom 214 is made of glass in the present embodiment. However, it can also be made of another, optically transparent material, or of a non-transparent material.

The tray 200 can be displaced on the shelf 104 in the direction of the longitudinal extent of the guide rails 204, so that when the refrigerator door 106 is opened, the tray 200 supporting on the shelf 104 can be at least partially displaced out of the interior 102 of the refrigerator 100 in order to move it onto the shelf 104 to place or remove refrigerated goods to be cooled. This displacement is limited by a pull-out barrier 210 which has a stop 216 arranged on the guide rail 204 and a counter-stop 218 arranged on the frame 202. The stop 216 has a contact surface 220 and the counter-stop 218 has a mating contact surface 222, which are in contact with each other when reaching the maximum pull-out position defined by the pull-out lock 210 and thus prevent a further displacement of the tray 200.

After items of refrigerated goods have been placed on or removed from the floor 214, the tray 200 can subsequently be relocated into the interior 102 and the interior 102 can be closed again by the refrigerator door 106. In this case, a slide-in barrier 212, which limits a displacement of the tray 200 in the insertion direction on the shelf 104, prevents the tray 200 from abutting against a rear wall delimiting the interior 102 of the refrigerator 100.

Fig. 3 shows that the tray 200 has rollers 300 arranged on its opposite longitudinal sides 208, which roll on the shelf 104 during the displacement of the tray 200. The rollers 300 are made of plastic in the present embodiment. But they can also be made of a rubbery, similar mechanical properties having material.

Fig. 4 3 shows that the rollers 300 each have two roller sidewalls, of which the outside roller sidewall 402 cooperates with a guide surface 400 of the guide rail 204 to guide the tray 200 during a displacement on the shelf 104. Thus, in the present embodiment, the planes of the roller sidewall 402 and the guide surface are parallel to each other while the plane of the shelf 104 is perpendicular thereto.

Fig. 5 shows two inserted into the frame 202 of the tray 200 trays 500. In the shells 500 informal, liquid and / or pourable refrigerated goods can be stored and removed if necessary with the tray together. The shells 500 in this case have a bottom portion 502, which is designed for positive insertion into the frame 202 of the tray 200. Thus, the trays 500 inserted into the frame 202 can not experience any unwanted displacement when the tray 200 with the trays 500 is moved out of the interior 102 of the refrigeration device 100 or into it. In addition, unwanted displacement of the trays 500 on the tray 200 is reliably prevented even when the tray 200 is lifted with the trays 500 from the shelf 104 and removed from the interior 102 of the refrigerator 100 to with the refrigerated goods in the trays 500 on to be placed at a table.

Further shows Fig. 5 in that two rollers 300 are arranged at a distance from one another on each longitudinal side 208 in the extension or insertion direction, ie in the direction of the longitudinal extent of the guide rails 204.

Thus, after opening the interior 102 of the refrigeration device 100 by pivoting the refrigerator door 106, the tray 200 can be moved out of the inner space 102 by rolling the rollers 300 on the shelf 104 until the pull-out lock 210 stops this displacement process. Now, items of refrigerated goods can be removed from the trays 500 or placed there when a tray 500 is inserted into the frame 202. If no tray 500 is inserted, items of refrigerated goods may be placed on or removed from the bottom 214 of the tray 200 there. Alternatively, the tray 200 with or without tray 500 or trays 500 can also be completely lifted off the shelf 104 and removed from the interior 102 of the refrigerator 100, for example, to place it on a table.

After use, the tray 200 can again be placed with its rollers 300 on the shelf 104 and / or displaced into the interior 102 of the refrigerator, depending on whether the tray 200 has been lifted off the shelf 104, or only out of the interior 102 has been moved out , Finally, the interior 102 of the refrigeration device 100 can be closed again by pivoting the refrigerator door 106.
