Humidifier with ultraviolet disinfection
First Claim
1. A humidifier system comprising:
- a humidifier housing defining an air inlet, and air outlet, and a fluid flow path therebetween, the fluid flow path being adapted to direct air through the humidifier housing;
an atomizing chamber at a first portion of the fluid flow path, the atomizing chamber being adapted to increase the moisture content of a volume of air circulating through the fluid flow path;
an ultraviolet light source at a second portion of the fluid flow path, the ultraviolet light source being adapted to expose the volume of humidified air from the atomizing chamber with germicidal light prior to its release from the humidifier housing at the air outlet; and
a base station having a blower to draw ambient air into the humidifier housing.

Abstract
A humidifier for treating humidified air with germicidal light is provided. The humidifier includes a water reservoir, an atomizer to atomize a supply of water, and an ultraviolet light source to expose the atomized water to germicidal light. The ultraviolet light source extends vertically within a cylindrical channel to irradiate the atomized water dissipating upwardly from the atomizer. The water reservoir can include a carbon filter and a hardness-removing module for removing containments and metal oxides from the water supply. A control panel indicates the remaining useful life of the ultraviolet light source, the carbon filter and the hardness-removing module based on historical humidifier usage and water quality levels.

7. A method for humidifying air, comprising:
-
providing a fluid flow path in communication with the ambient environment, the fluid flow path including an inlet, an atomizing chamber, an ultraviolet light source, and an outlet; increasing the moisture content of ambient air circulating through the atomizing chamber in the fluid flow path; exposing the resulting humidified air escaping from the atomizing chamber with ultraviolet light from the ultraviolet light source to inactivate microorganisms in the humidified air, the ultraviolet light source being in the fluid flow path downstream of the atomizing chamber; and discharging the humidified air from the fluid flow path outlet and into the ambient environment, wherein the increased moisture content originates from a water supply within a water reservoir, and wherein the water reservoir defines a toroidal core, the fluid flow path extending vertically through the toroidal core. - View Dependent Claims (8, 9, 10, 11)
