Humidifier having an anti-contamination system
View Patent ↗A humidifier is provided having a base including a chamber for receiving water, at least one reservoir removably mounted on the base for providing water to the base chamber, and an atomizer provided in the base for aerosolizing water from the base chamber. A duct is removably mounted on the base, the duct enclosing the atomizer and venting humidified air from the humidifier. An anti-contamination system is in communication with the duct and includes a housing, an ultraviolet (UV) light source mounted within the housing for emitting UV light to interact with at least one of the aerosolized water and humidified air, and a window at least partially transparent to UV light provided between the anti-contamination system and the duct. Embodiments may include a reflective member provided within the housing for reflecting UV light through the window.
1. A humidifier, comprising:
a base including a chamber for receiving water;
at least one reservoir removably mounted on the base for providing water to the base chamber;
an atomizer provided in the base for aerosolizing water from the base chamber;
a duct removably mounted on the base, the duct including a first chamber and a second chamber, the first and second chambers separated by a baffle that prevents fluid communication therebetween, the second chamber enclosing the atomizer and venting humidified air from the humidifier, the second chamber including an aperture; and
an anti-contamination system mounted to the base and arranged to be received within the duct first chamber, the anti-contamination system including a housing, an ultraviolet (UV) light source mounted within the housing for emitting UV light to interact with at least one of the aerosolized water and humidified air, and a window at least partially transparent to UV light mounted in the housing, wherein the window is aligned with the aperture to provide UV light to the second chamber.
2. The humidifier of claim 1 , wherein the housing includes a reflective member for reflecting UV light through the window.
3. The humidifier of claim 1 , wherein the second chamber includes a reflective member adjacent to the window to at least partially reflect light emitted from the UV light source.
4. The humidifier of claim 1 , wherein the base includes a heating unit for heating water in the base.
5. The humidifier of claim 1 , further comprising a fan disposed in the base for providing air to the duct, wherein the aerosolized water is entrained in the air to create humidified air.
6. The humidifier of claim 1 , wherein the reservoir includes a collar removably mounted on a bottom surface of the reservoir, the collar including a valve actuated when the reservoir is positioned on the base to release water into the base chamber.
7. The humidifier of claim 1 , further comprising a seal between the anti-contamination system and the second chamber.
8. The humidifier of claim 1 , wherein the anti-contamination system includes a safety switch such that power to the UV light source is disabled when the duct is removed from the base.
9. A humidifier, comprising:
a base including a chamber for receiving water;
at least one reservoir removably mounted on the base for providing water to the base chamber;
an atomizer provided in the base for aerosolizing water from the base chamber;
a duct removably mounted on the base, the duct having a chamber enclosing the atomizer and venting humidified air from the humidifier; and
an anti-contamination system external to the chamber such that fluid communication with the chamber is prevented and including a housing, an ultraviolet (UV) light source mounted within the housing for emitting UV light to interact with at least one of the aerosolized water and humidified air, a window at least partially transparent to UV light provided between the anti-contamination system and the duct, and a reflective member provided within the housing for reflecting UV light through the window.
10. The humidifier of claim 9 , wherein the duct includes a reflective member adjacent to the window to at least partially reflect light emitted from the UV light source.
11. The humidifier of claim 9 , wherein the anti-contamination system is mounted to the base.
12. The humidifier of claim 9 , wherein the anti-contamination system is mounted within the duct.
13. The humidifier of claim 12 , wherein the duct includes a first chamber including the anti-contamination system.
14. The humidifier of claim 9 , wherein the window is mounted to the duct.
15. The humidifier of claim 9 , wherein the window is mounted in the anti-contamination system.
16. The humidifier of claim 9 , further comprising electrical connections on the duct configured to mate with corresponding electrical connections on the base to provide power to the UV light source.
17. The humidifier of claim 9 , wherein the base includes a heating unit for heating water in the base.
18. The humidifier of claim 9 , further comprising a fan disposed in the base for providing air to the duct, wherein the aerosolized water is entrained in the air to create humidified air.
19. The humidifier of claim 9 , wherein the reservoir includes a collar removably mounted on a bottom surface of the reservoir, the collar including a valve actuated when the reservoir is positioned on the base to release water into the base chamber.
20. A humidifier, comprising:
a base including a chamber for receiving water;
at least one reservoir removably mounted on the base for providing water to the base chamber, the reservoir including a collar removably mounted on a bottom surface of the reservoir, the collar including a valve actuated when the reservoir is positioned on the base to release water into the base chamber;
an atomizer provided in the base for aerosolizing water from the base chamber;
a duct removably mounted on the base, the duct having a chamber enclosing the atomizer and venting humidified air from the humidifier; and
an anti-contamination system external to the chamber such that fluid communication with the chamber is prevented and including a housing, an ultraviolet (UV) light source mounted within the housing for emitting UV light to interact with at least one of the aerosolized water and humidified air, and a window at least partially transparent to UV light provided between the anti-contamination system and the duct.
21. The humidifier of claim 20 , wherein the housing includes a reflective member for reflecting UV light through the window.
22. The humidifier of claim 20 , wherein the duct includes a reflective member adjacent to the window to at least partially reflect light emitted from the UV light source.
23. The humidifier of claim 20 , wherein the anti-contamination system is mounted to the base.
24. The humidifier of claim 20 , wherein the anti-contamination system is mounted within the duct.
