Claims19
An evaporator assembly for use in an evaporative humidifier, the evaporator assembly comprising:
- a first evaporative element having a tubular shape and comprised of a multi-layered arrangement of a porous material,
- a second evaporative element stacked on the first evaporative element, and
- an evaporator frame that supports the first evaporative element and the second evaporative element, the evaporator frame comprising a middle shelf arranged between the first and second evaporative elements such that adjacent, proximal ends of the first and second evaporative elements contact the middle shelf, wherein the middle shelf comprises a first trough on a first side of the middle shelf, and a second trough on a second side of the middle shelf such that the adjacent, proximal ends of the first and second evaporative elements are each disposed within a respective trough of the middle shelf,
- wherein the porous material comprises a yarn comprising anti-bacterial fibres, and
- wherein the evaporator frame comprises at least one of:
- an outer grille surrounding an outer surface of the multi-layered arrangement;
- and
- an inner grille extending over an inner surface of the multi-layered arrangement.
