ABSTRACT:
A coolmist humidifier appliance which emits liquid in the form of mist or fog to achieve enhanced humidification includes a lower housing part which is positionable on a support surface and an upper housing part which is removably positionable on the lower housing part and includes a motor and an impeller assembly for drawing liquid upwardly from the lower housing part and spraying it radially outwardly against a ring of comb teeth so as to form liquid droplets outside of the ring of comb teeth. The upper housing part includes a discharge opening and a guide wall which extends downwardly toward the lower housing part and toward the discharge opening along a spiral curve so that the liquid droplets will move toward the discharge opening along a volute passageway.
