Evaporative Personal Air Cooler

Abstract

An evaporative air cooler for cooling ambient air includes a housing, a tank, a misting structure, a filter structure, and a fan. The housing includes a top panel, a bottom panel, and side panels defining an interior of the evaporative air cooler. The tank is positioned adjacent to the top panel and at least one of the side panels. The tank receives, stores, and releases liquid. The misting structure comprises a mister and a misting structure coupling and creates a mist within the evaporative air cooler. The filter structure has a plurality of filters for absorbing the mist. The fan draws the ambient air into the evaporative air cooler and directs the ambient air through the filter structure and out of the evaporative air cooler. The evaporative air cooler cools the ambient air by at least one of the mist and the filter structure before exiting the evaporative air cooler.

Claims

1. The evaporative air cooler of claim 11, wherein the plurality of filters are aligned parallel to each other and define air gaps between the plurality of filters; and wherein the ambient air is cooled before exiting the evaporative air cooler.

2. The evaporative air cooler of claim 11, wherein the misting structure distributes the mist into the ambient air and onto the plurality of filters.

3. The evaporative air cooler of claim 11, wherein the tank comprises a liquid inlet and a liquid outlet, wherein liquid enters the tank through the liquid inlet and exits the tank through the liquid outlet, wherein the misting structure is in liquid communication with the tank and configured to create a mist as the liquid flows through the liquid outlet, and wherein the mister is positioned within the tank wherein the liquid flows from the tank toward the mister.

4. The evaporative air cooler of claim 11, wherein the misting structure creates a first volume of mist when the fan is at a first speed, and wherein the misting structure creates a second volume of mist when the fan is at a second speed.

5. The evaporative air cooler of claim 4, wherein the first volume is larger than the second volume and the first speed is faster than the second speed.

6. The evaporative air cooler of claim 11, further comprising: an internal assembly configured to form a seal with the fan, wherein the seal causes the ambient air to exit the evaporative air cooler with a greater force than when entering the evaporative air cooler.

7. The evaporative air cooler of claim 6, wherein the internal assembly comprises the filter structure and a drawer.

8. The evaporative air cooler of claim 11, wherein the filter structure is configured for removal from the evaporative air cooler, and wherein the filter structure and the plurality of filters are washable and reusable.

9. The evaporative air cooler of claim 11, wherein the plurality of filters are formed of sponge-like material.

10. The evaporative air cooler of claim 11, further comprising: a shroud adjacent to an underside of the tank, wherein the shroud is v-shaped.

11. An evaporative air cooler for cooling ambient air, comprising: a housing with a top panel, a bottom panel, and side panels defining an interior of the evaporative air cooler; and a tank positioned adjacent to the top panel and at least one of the side panels, wherein the tank is configured to receive, store, and release liquid; a misting structure comprising a mister and a misting structure coupling, wherein the misting structure is configured to create a mist within the evaporative air cooler; a filter structure with a plurality of filters, wherein the plurality of filters are configured to absorb the mist; and a fan configured to draw the ambient air into the evaporative air cooler, wherein the ambient air is cooled by at least one of the mist and the filter structure, and wherein the fan directs the ambient air thorough the filter structure and out of the evaporative air cooler.

12. The evaporative air cooler of claim 11, wherein the plurality of filters are formed of a sponge material and positioned to define gaps between the plurality of filters.

13. The evaporative air cooler of claim 11, wherein the filter structure is positioned in a drawer, and wherein the drawer is removable from the portable evaporative air cooler.

14. The evaporative air cooler of claim 13, further comprising: a front grill with a tab for pulling the drawer from the portable evaporative air cooler.

15. The evaporative air cooler of claim 11, wherein the plurality of filters are removable from the portable evaporative air cooler and configured to be soaked with liquid prior to entering the portable evaporative a
