Fig. 1 shows a refrigerator as an exemplary embodiment of a refrigeration device 100 with an upper refrigerator door 102 and a lower refrigerator door 104 on its refrigeration device front. The refrigerator is used, for example, to cool food and comprises a refrigerant circuit with an evaporator (not shown), a compressor (not shown), a condenser (not shown) and a throttle element (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.e. Air inside the refrigerator, is evaporated.

The throttling device is a device for the constant reduction of the pressure by reducing the cross-section.

The refrigerant is a fluid that is used for heat transfer in the refrigeration generating system that operates at low temperature and low pressure of the fluid Absorbs heat and gives off heat at a higher temperature and higher pressure of the fluid, usually including changes in state of the fluid.

With the upper refrigerator door 102, an upper cold compartment 106 can be opened, which in the present exemplary embodiment is designed as a cold compartment. With the lower refrigerator door 104, a lower cold compartment 108 can be opened, which in the present exemplary embodiment is designed as a refrigerated compartment.

The lower refrigerator door 104 has an inner door 112 which, in the present exemplary embodiment, has a first spar 114 and a second spar 116, which extend in the vertical direction Z of the refrigeration appliance. A door rack 116 is mounted between the two bars 114, 116 such that it can be displaced in a height displacement direction I, which likewise extends in the vertical direction Z of the refrigeration device.

A first guide element 118 and a second guide element 122 are arranged on the inner door 112 in order to store the door rack 110 in a height-adjustable manner in the height displacement direction I. The first guide element 118 and the second guide element 122 are arranged at a distance from one another between the first spar 114 and the second spar 116. In the present exemplary embodiment, the first guide element 118 is formed by a first guide rail 120 and the second guide element 122 is formed by a second guide rail 124.

The Fig. 2 and 3 show that the door rack 110 has a refrigerated goods receiving area 206 for receiving refrigerated goods, such as drinks bottles.

Also show the Fig. 2 and 3 that the first guide element 118, in the present exemplary embodiment the first guide rail 120, is fastened to the inner door 112 of the refrigeration device 100 with an upper bore 202 and a lower bore 204.

Furthermore, the Fig. 2 and 3 that the door rack 110 has an operating element 200 arranged on the top of the door rack 110 according to the present invention. In the present exemplary embodiment, the operating element 200 is designed as a pushbutton and allows locking, as will be done later, by actuation is described, to be solved with the first guide rail 120, in particular to lower the door rack 110 in the vertical displacement direction I in the vertical direction of the refrigeration device. In contrast, in order to move the door rack 110 upward in the vertical direction Z of the refrigerator in the direction of height displacement I, in the present exemplary embodiment no actuation of the actuating element 200 is necessary, but a free-wheel mechanism is provided for this purpose.

The Fig. 4 shows that the first guide rail 120 is fastened by means of the upper bore 202 and the lower bore 204 in the inner door 112, through which a screw extends. Furthermore, the Fig. 4 that the first guide element 118, in the present exemplary embodiment the first guide rail 120, is arranged at a distance 400 from the first spar 114, the distance 400 being greater than zero in the present exemplary embodiment. Also shows the Fig. 4 that the second guide rail 124 is fixed by means of the upper bore 202 and the lower bore 204 in the inner door 112, through which a screw extends. Furthermore, the Fig. 4 that the second guide element 122, in the present exemplary embodiment the second guide rail 124, is arranged at a distance 402 from the second spar 116, the distance 402 being greater than zero in the present exemplary embodiment.

The Fig. 5 shows in an enlarged representation that the first guide element 118, in the present exemplary embodiment the first guide rail 112, is arranged at a distance 400 greater than zero from the first spar 114.

This ensures that deformations of the spar 114 during the foaming of the inner door 112 can lead to a deformation of the spar 114, but do not cause a displacement of the first guide rail 118. It goes without saying that these explanations apply analogously to the second spar 116 with the second guide element 122, in the present exemplary embodiment with the second guide rail 124.

The bores 202, 204 are made with the aid of a drilling template (not shown), so that it is ensured that the bores 202, 204 are made at the positions provided for this and thus the desired spacing 400 exhibit. As an alternative to using a drilling template, it can also be provided that the first guide element 118 and the second guide element 122 are rigidly connected to one another by a connecting element (not shown) so that they do not experience any deformation during the foaming.

Fig. 6 shows that in terms of the Fig. 4 and 5 The embodiments made apply to the first spar 114 and the first guide element 118 with the first guide rail 120 analogously to the second spar 116 and the second guide element 122 with the second guide rail 124.

Fig. 7 shows that in the present exemplary embodiment the first guide rail 120 and the second guide rail 124 each have a corrugated profile 702 with a plurality of depressions 700, each of the depressions 700 defining a certain height position of the door rack 110 in the vertical direction Z of the refrigerator. The first guide rail 120 and the second guide rail 124 are designed as a plastic injection-molded part in the present exemplary embodiment.

In order to lock the door rack 110 in a desired height position, the door rack 110 in the present exemplary embodiment has a first counter-guide element 704 and a second counter-guide element 706, the first counter-guide element 704 being assigned to the first guide rail 120 and the second counter-guide element 706 to the second guide rail 124 is.

In the present exemplary embodiment, both the first counter-guide element 704 and the second counter-guide element 706 each have an engagement element 708, which in the present exemplary embodiment is designed as a latching cam 710 and is thus adapted to the recess 700 formed by the wave profile 720.

In the present exemplary embodiment, the depressions 700 of the corrugated profile 720 are arranged in such a way that they are open in the refrigeration appliance depth direction X, specifically in the direction of the upper refrigeration appliance door 102 and the lower refrigeration appliance door 104. What is achieved in this way is that a torque when the door rack 106 is displaced does not lead to a deformation of the first guide element 118 or the second guide element 122 in the width direction of the refrigerator Y, that is, in the direction of the first spar 114 or the second spar 116, but leads to a deformation in the refrigeration device depth direction X of the refrigeration device. This counteracts a possible tilting of the door rack 106 due to a deformation of the first guide element 118 and the second guide element 122 in the width direction Y of the refrigerator.

The in Fig. 7 The arrow shown indicates that the locking cam 710 can be moved out of the recess 700 by means of the operating element 200, so that the locking cam 710 no longer engages with the recess 700 and locks the door rack 110 in the respective height position. It is now possible to move the door rack 110 both upwards and downwards in the direction of height displacement I or in the vertical direction Z of the refrigeration device.

In the present exemplary embodiment, the latching cam 710 is resiliently pretensioned by a spring element 712, so that it returns to its starting position again after the actuating element 200 is not actuated. Thus, the door rack 110 is locked again at a desired height.

The in Fig. 7 In the direction of rotation of the actuating element 200 shown by the arrow, when the door rack 110 is displaced without actuating the actuating element 200, the latching cam 710 is pivoted out of the recess 700 until the in Fig. 8 position shown is reached. It is thus possible to displace the door rack 110 in order to lift it in the vertical direction Z or the vertical displacement direction I without the actuating element 200 having been actuated. The resilient preload in turn causes the locking cams 710 to engage again in one of the recesses 700 after the lifting movement has been completed. One-handed operation is thus possible in order to lift the door rack 110 with one hand without actuating the actuating element 200 in the vertical direction Z or the vertical displacement direction I.

However, in order to lower the door rack 110 in the vertical direction Z or the vertical displacement direction I, actuation of the actuating element 200 is necessary in order to lock the latching cam 710 by the in Fig. 7 arrow direction shown to move out of the recess 700 in order to cancel the engagement between the recess 700 and the locking cam 710. A pivoting movement of the locking cam 710 in an opposite direction, however, is prevented by stop means (not shown). Lowering is therefore only possible when the actuating element 200 has been actuated. In other words, lowering the door rack 110 is only possible with two-hand operation.

The Fig. 9 and 10 show that the door rack 110 has an extension 900 in the present exemplary embodiment. In the present exemplary embodiment, the extension 900 has an extension in the vertical direction Z of the refrigeration device which is greater than the height 916 of the refrigerated goods receiving area 206 of the door rack 110.

A first engagement element 902 and a second engagement element 904 are arranged on the extension 900, wherein in the present exemplary embodiment the first engagement element 902 is arranged in the refrigerator vertical direction Z at the upper end of the extension 900, while the second engagement element 904 in the refrigerator vertical direction Z at the lower End of the extension 900 is arranged, so that in the present embodiment, the distance 906 between the first engagement element 902 and the second engagement element 904 is maximized in order to counteract tilting of the door rack 110 when it is shifted in the direction of displacement I or upright direction Z of the refrigerator.

In the present exemplary embodiment, the first engagement element 902 is formed by an upper roller 912 and the second engagement element 904 is formed by a lower roller 914.

Fig. 9 shows that the first engagement element 902 and the second engagement element 904 are arranged on the rear wall 908 of the door rack 110, while Fig. 10 shows that the first engagement element 902 and the second engagement element 84 are arranged on a side wall 910 of the door compartment 110.

The Fig. 11 shows that in Fig. 9 Shown embodiment with the arranged on the rear wall 908 first engagement element 902 and second engagement element 904, while the Fig. 12 this in Fig. 10 The illustrated embodiment with the first engagement element 902 and second engagement element 904 arranged on the side wall 910 shows. <b> List of reference symbols </b> 100 Refrigeration device 700 deepening 102 upper refrigerator door 702 Wave profile 104 lower refrigerator door 704 first counter-guide element 106 upper cold compartment 706 second counter guide element 108 lower cold compartment 708 Engagement element 110 Door racks 710 Locking cams 112 Interior door 712 Spring element 114 first spar 116 second spar 900 renewal 118 first guide element 902 first engagement element 120 first guide rail 904 second engagement element 122 second guide element 906 distance 124 second guide rail 908 Back wall 910 Side wall 200 Actuator 912 upper role 202 upper hole 914 lower roll 204 lower hole 916 height 206 Chilled goods receiving area I.
