Problems solved by technology

[0003] The disadvantage of the siphon solution is that until the siphon is full of water - that is, for example until the end of the first defrost cycle - ambient air and moisture can flow into the cooling chamber or into the evaporator via the defrost water channel and cause Pollution and Energy Loss
[0005] However, such fully water-soluble channel closures would be complex to manufacture and not very mechanically stable
As a result, in some cases the closure is not completely reliable since it cannot withstand mechanical stress

Embodiment Construction

[0043] figure 1 is a schematic diagram of a longitudinal section through the defrosting water channel 2 of the refrigeration device, which guides the defrosting water from the evaporation chamber 6 along the flow direction F. The defrosting water passage 2 is a hose and includes a U-shaped siphon 5 . In the flow direction F of the defrosting water, the channel closure 1 is arranged behind the siphon 5 so that it only comes into contact with the defrosting water when the siphon 5 is full. The channel closing device 1 is a plastic disc which is fixed to the inner wall of the hose by means of a water soluble adhesive 20 . If the channel closure 1 comes into contact with the defrosting water after the siphon 5 has been filled, the adhesive 20 dissolves and the disk 1 and the inner wall of the defrosting water channel 2 disintegrate. It is then arranged parallel to the flow direction F or as the defrost water is flushed out of the defrost water channel 2 , thereby opening said ch...

Abstract

The invention relates to a refrigeration device, in particular a NoFrost refrigeration device, comprising a defrosting water channel (2) which is closed by channel closure means (1). Said channel closure means are not or only partially water-soluble and are secured to or into the defrosting water channel (2) by means of water-soluble securing means, preferably, a water-soluble adhesive.

Description

technical field [0001] The present invention relates to a refrigerating device, and in particular, to a frost-free refrigerating device comprising a defrosting water passage closed by passage closing means. Background technique [0002] In refrigeration units of the type described above, air is circulated into the refrigeration chamber from an evaporator located outside the actual refrigeration chamber by means of a circulating air system. Ice forms on the evaporator, and the evaporator is periodically defrosted, wherein defrost water is drained, for example, through a defrost water channel into the evaporator tray. In order to prevent the flow of ambient air via the defrost water channel into the refrigerating chamber or, in the case of frost-free installations, into the evaporator chamber, a siphon is usually integrated in the defrost water channel. This is filled with defrost water, thereby preventing any further air exchange. [0003] The disadvantage of the siphon sol...
