Claims
- 1. A portable evaporative humidifier comprising:
- a. base including a portion defining a reservoir for holding water,
- b. a substantially cylindrical housing mounted on said base over said reservoir, said housing having an air inlet through an upper portion of the housing and an air outlet through a portion of a sidewall of the housing,
- c. a cylindrically shaped wick filter seated in said reservoir and extending into said housing, said cylindrically shaped wick filter having an open end and a sidewall,
- d. a cylindrically shaded heater having a radial periphery, said heater being substantially radially aligned with said air inlet and axially aligned with said cylindrically shaped wick filter;
- e. a fan positioned below, said heater inside said housing and
- f. a deflector positioned between said fan and said cylindrically shaped wick filter for directing air flow into said open end of said wick filter;
- wherein during operation of said humidifier, air is drawn inside said housing through said air inlet, and through said radial periphery of said heater by said fan thereby heating the air, the heated air is forced by the fan through the deflector into the open end of the wick filter and forced through the sidewall of the wick filter thereby humidifying the air, the humidified air is discharged from the housing through the air outlet.
- 2. The evaporative humidifier of claim 1, wherein said sidewall of said housing is cylindrically shaped.
- 3. The evaporative humidifier of claim 1 and further including a heater inside said housing for heating the air drawn in.
- 4. The evaporative humidifier of claim 3 wherein the heater is positioned to heat the air drawn in before passage into said cylindrically shaped wick filter.
- 5. The evaporative humidifier of claim 4 wherein said heater is a cylindrically shaped cage resistance wire heater.
- 6. The evaporative humidifier of claim 5 and further including a deflector for deflecting the air drawn in down into said cylindrically shaped wick filter.
- 7. The evaporative humidifier of claim 6 further including a water supply tank mounted on said base for supplying water to said reservoir.
- 8. The evaporative humidifier of claim 7, wherein said air inlet is above said air outlet.
- 9. The evaporative humidifier of claim 8, wherein said fan includes a motor having a drive shaft and a set of radially extending blades on said drive shaft.
- 10. The evaporative humidifier of claim 9, wherein said reservoir includes a hub having radially extending ribs for holding said wick filter in its cylindrical shape.
- 11. The evaporative humidifier of claim 10, wherein said fan is located above said wick filter.
- 12. The evaporative humidifier of claim 11, wherein said heater is a cage heater.
