Problems solved by technology

The defrost heater can be disassembled for maintenance purposes by removing the retaining device from the pipe ring, but disassembly and especially reassembly is difficult because the evaporator is usually located inaccessibly on the rear wall of the inner chamber The side wall on the top and closely opposite the pipe ring prevents the retaining device from being inserted into the pipe ring again

Embodiment Construction

[0022] figure 1 A schematic sectional view of the body 1 of the domestic refrigeration appliance is shown along a section plane extending vertically and in the depth direction. The interior 2 of the body 1 is delimited by an inner container 3 deep-drawn in one piece from plastic. A partition wall 4 suspended on the side wall of the inner container 3 divides the inner chamber 2 into a storage chamber 5 and an evaporator chamber 6 . An evaporator 7 is fitted in the evaporator chamber 6 . The lamellae of the evaporator 7 extend parallel to the cross-sectional plane, so that air can circulate between the lamellae in the vertical direction, and each of the lamellae rests with a longitudinal edge on the rear wall 8 of the inner container or against on the partition wall 4. The evaporator chamber 6 and the storage chamber 5 are connected via two passages 9 , 10 of the partition wall 4 . A fan 11 is arranged on one of the passages in order to drive the air circulation through the ...

Abstract

The invention relates to a frost-free refrigeration appliance having an inner chamber (2) divided by a partition wall (4) into an evaporator chamber (6) receiving an evaporator (7) and a defrosting heating device (31) ) and the storage chamber (5) cooled by the evaporator chamber (6). The partition wall (4) and the evaporator (7) are anchored independently of each other on the wall of the inner chamber (2). The defrosting heating device (31) is not connected to the evaporator (7) and is fixed on the partition wall (4).

Description

technical field [0001] The invention relates to a frost-free refrigeration appliance having an inner chamber which is divided by a partition wall into a receiving evaporator chamber and a storage chamber cooled by the evaporator chamber. In addition to the evaporator, a defrost heating device, which serves to defrost the evaporator, is usually also located in the evaporator compartment of the refrigeration appliance. The evaporator is welded firmly into the coolant circuit of the refrigeration appliance and practically cannot be detached from the finished refrigeration appliance without damaging the finished refrigeration appliance for reasonable cost. Repairs must therefore be made such that the evaporator can remain on site. Background technique [0002] According to conventional technology, the defrost heater is fixed on the evaporator by means of a plate-shaped holding device with a plurality of holes, wherein the defrost heater is inserted into one of the holes and the...
