Humidifier with ultraviolet germicidial light
View Patent ↗A humidifier which includes a reservoir of water in fluid communication with an evaporation chamber. Some of the water that enters the evaporation chamber vaporizes and enters the ambient environment. A remainder of the water does not evaporate and flows into a collection container in fluid communication with the reservoir. The unevaporated water is then exposed to a source of ultraviolet radiation which helps to inhibit the ability of various organisms contained therein to reproduce in the future. After irradiation, the unevaporated water travels from the collection container to the reservoir.
1. An apparatus for humidifying air in rooms, the apparatus comprising:
a reservoir containing water;
an evaporation chamber in fluid communication with the reservoir and receiving water from the reservoir, a first portion of the water in the evaporation chamber evaporates and becomes water vapor, which travels into ambient air, and a remaining portion of the water in the evaporation chamber does not evaporate and flows into a collection container in fluid communication with the reservoir such that the remaining portion of the water flows from the collection container to the reservoir;
at least one of a wick and an evaporative pad in the evaporative chamber which receives at least a portion of the water;
a fan that forces ambient air through the evaporation chamber to regulate a rate of evaporation of the water from the at least one of the wick and the evaporative pad; and
a source of ultraviolet radiation which irradiates the remaining portion of the water before the remaining portion of the water returns to the reservoir, helping to inhibit the ability of various micro-organisms, such as bacteria and viruses, and other organisms which are present in the remaining portion of the water to subsequently reproduce.
2. The apparatus of claim 1 , wherein the reservoir is substantially open to the atmosphere.
3. The apparatus of claim 1 further comprising:
a piping network wherein the water flows from the reservoir to the evaporation chamber through the piping network.
4. The apparatus of claim 3 , wherein the piping network has at least one mechanical pump.
5. The apparatus of claim 1 , wherein the evaporation chamber contains at least one air inlet and at least one air outlet.
6. The apparatus of claim 5 , wherein the ambient air enters the evaporation chamber through the at least one air inlet, which is located in a top of the evaporation chamber.
7. The apparatus of claim 5 , wherein the water vapor generally exits the evaporation chamber through the at least one air outlet, which is located in a side of the evaporation chamber.
8. The apparatus of claim 1 , wherein the evaporation chamber contains at least one opening.
9. An apparatus for humidifying air in rooms, the apparatus comprising:
a reservoir containing water;
a piping network for transporting the water from the reservoir into an evaporation chamber;
the evaporation chamber being in fluid communication with the reservoir and receiving water from the reservoir, a first portion of the water in the evaporation chamber evaporates and becomes water vapor, which travels into ambient air, and a remaining portion of the water in the evaporation chamber does not evaporate and flows directly into a collection container and then directly re-enters the piping network;
at least one of a wick and an evaporative pad in the evaporative chamber which receives at least a portion of the water;
a fan that forces ambient air through the evaporation chamber to regulate a rate of evaporation of the water from the at least one of the wick and the evaporative pad; and
a source of ultraviolet radiation which irradiates the remaining portion of the water before the remaining portion of the water re-enters the piping network, helping to inhibit the ability of various micro-organisms, such as bacteria and viruses, and other organisms which are present in the remaining portion of the water to subsequently reproduce.
