Abstract

A portable, self-contained cooling device includes a base, a reservoir fixedly secured to the base and arranged to store a liquid usable for cooling. The device also includes a fan assembly fixedly secured to the reservoir at a location above the reservoir. The fan assembly includes a fan configured to generate an airflow, a motor configured to operate the fan, and a nozzle disposed to spray the liquid as a mist into the airflow. The device also includes a power source configured to power the fan, the power source being disposed at an elevation adjacent to or below the reservoir.

Claims (73)

1. A portable, self-contained cooling device, comprising:

a base;

an enclosed reservoir fixedly secured to the base, the reservoir being arranged to store a liquid usable for cooling;

a fan assembly directly coupled to the reservoir and is indirectly coupled to the base only by the reservoir and a handle, the fan assembly comprising:

a fan having a central axis and configured to generate an airflow;

a motor configured to operate the fan; and

a nozzle disposed at the central axis of the fan and configured to spray the liquid into the airflow;

a front diffuser;

a rear diffuser;

a hose configured to direct the liquid toward the nozzle, proximate to the central axis, the hose being disposed between the front diffuser and the rear diffuser in both a front-rear axis and an up-down axis, wherein the hose is in fluid communication with the reservoir; and

a power source configured to power the fan, the power source being disposed within the base at an elevation completely below a top of the reservoir, wherein a weight of the power source at the elevation is sufficient to lower a center of gravity of the portable, self-contained cooling device such that the portable, self-contained cooling device is less prone to tipping.

2. The cooling device of claim 1 , comprising a battery compartment in the base.

3. The cooling device of claim 2 , wherein the battery compartment is disposed below the reservoir.

4. The cooling device of claim 1 , wherein the reservoir comprises a fill port for introducing the liquid into the reservoir the fill port being accessible with the fan assembly fixed to the reservoir.

5. A portable, self-contained cooling device, comprising:

an enclosed reservoir arranged to store a liquid usable for cooling;

a fan assembly fixedly secured to the reservoir at a location above the reservoir, comprising:

a fan having a central axis and configured to generate an airflow;

a motor configured to operate the fan; and

a nozzle disposed at the central axis and configured to spray the liquid into the airflow;

a front diffuser;

a rear diffuser;

a hose configured to direct the liquid toward the nozzle, proximate to the central axis, the hose being disposed between the front diffuser and the rear diffuser in both a front-rear axis and an up-down axis, wherein the hose is in fluid communication with the reservoir;

a pump configured pressurize the liquid to spray from the nozzle; and

a power source configured to power the fan and the pump, the power source being disposed at an elevation completely below the top of the reservoir, wherein a weight of the power source at the elevation is sufficient to lower a center of gravity of the portable, self-contained cooling device such that the portable, self-contained cooling device is less prone to tipping.

6. The cooling device of claim 5 , wherein the reservoir comprises a fill port for introducing the liquid into the reservoir the fill port being accessible with the fan assembly fixed to the reservoir.

7. The cooling device of claim 5 , comprising a base having a width wider than the reservoir, the base being disposed below the reservoir and being configured to provide stability to the cooling device.

8. The cooling device of claim 5 , comprising a battery compartment in a base fixedly attached to the reservoir, wherein the battery compartment is disposed below the reservoir.

9. A portable, self-contained cooling device, comprising:

a base;

a reservoir fixedly secured at a location above the base, the reservoir being arranged to store a liquid usable for cooling;

a top assembly fixedly secured at a location above the reservoir, the top assembly comprising:

a fan having a central axis and configured to generate an airflow;

a motor configured to operate the fan; and

a nozzle disposed at the central axis of the fan and configured to spray the liquid into the airflow;

a front diffuser;

a rear diffuser;

a hose configured to direct the liquid toward the nozzle, proximate to the central axis, the hose being disposed between the front diffuser and the rear diffuser in both a front-rear axis and an up-down axis, wherein the hose is in fluid communication with the reservoir; and

a handle not in contact with the reservoir and extending adjacent the reservoir from the base to the top assembly, the handle defining a hand space between the reservoir and the handle, wherein the hand space is shaped to accommodate the fingers of a user for one-handed carry.

10. The cooling device of claim 9 , comprising a battery compartment in the base.

11. The cooling device of claim 10 , wherein the battery compartment is disposed below the reservoir, wherein a weight of a battery disposed within the battery compartment is sufficient to lower a center of gravity of the portable, self-contained cooling device such that the portable, self-contained cooling device is less prone to tipping.

12. The cooling device of claim 9 , wherein the reservoir comprises a fill port for introducing the liquid into the reservoir the fill port being accessible with the fan assembly fixed to reservoir.

13. The cooling device of claim 9 , wherein the top assembly includes a fan assembly comprising the fan and a pivot joint defining a horizontal axis, the fan assembly being swivelable about the horizontal axis.

14. A portable, self-contained cooling device for cooling air, the device comprising:

an enclosed reservoir arranged to hold a liquid;

a base configured to support the reservoir;

a pump configured to pump the liquid;

a fan assembly comprising:

a fan having a central axis and configured to intake air and expel air;

a motor configured to operate the fan; and

a nozzle disposed at the central axis of the fan and configured to spray the liquid into the expelled air;

a front diffuser;

a rear diffuser;

a hose configured to direct the liquid toward the nozzle, proximate to the central axis, the hose being disposed between the front diffuser and the rear diffuser in both a front-rear axis and an up-down axis, wherein the hose is in fluid communication with the reservoir;

a power source configured to power the pump and the motor; and

a handle extending from the base and the fan assembly and not the reservoir and configured such that the self-contained device can be carried one-handed,

wherein the self-contained device has a height and a width, the height being substantially greater than the width,

wherein the fan assembly is configured to swivel around a horizontal axis defined by a left pivot arm and a right pivot arm.

15. The self-contained device of claim 14 , wherein the reservoir is at least partly transparent.

16. The self-contained device of claim 14 , wherein the powering of the pump by the power source is controlled by a first switch.

17. The self-contained device of claim 14 , wherein the powering of the motor by the power source is controlled by a second switch.
