Abstract: A shower assembly is disclosed having a spray nozzle (41) through which liquid flows into a shower cabinet (10). The shower has a collecting container (22) for the liquid, the nozzle and container being integrated with a circulation system including a pump (33) with which the liquid in the collecting container can be circulated through the nozzle (41). The shower also has a mechanism (18, 20) by which the liquid either can be directed to the container (22) or directly to a sewage (21).

Abstract: In a freezer with a chamber, in which refrigerated surfaces tend to collect frost, with a moisture absorbing regenerable filter in order to lower the relative humidity of the freezing chamber air and counteract forming of frost therein, the filter has had to be removed and regenerated outside the freezer. This can be avoided if the air of the freezing chamber is conducted through a first flow path having a motor driven fan and a filter and ambient air is conducted through the fan and the filter in a second flow path for regeneration of the filter. An arrangement for the purpose is characterized in that the filter is arranged in a first heat-insulated flow path, intended for freezing chamber air and containing a motor driven fan, that a second heat-insulated flow path, intended for ambient air, is connected to the first one before and after a part thereof containing the filter and the fan, and that valves are arranged for shifting of the flow paths.
