This wall has an inner face in the compartment and an outer face and is formed therebetween with an array of throughgoing perforations. Respective flexible tubular extensions are provided on the outer face of the wall at the perforations. These extensions can be deformed to flake off lime formations adhering to the extensions. The extensions can be unitary with the wall, in which case the wall is made of an elastomer, or respective tubular liners in the perforations having outer ends projecting past the outer face can form the respective extensions. In this case each liner can have laterally projecting inner and outer ridges respectively bearing against the inner and outer faces of the wall.
