Abstract

The evaporative cooler and pad operates on the principle of cooling the air by evaporation of water passing through one or more evaporator pads in the cooler. The evaporation of water cools the air as it is drawn through the cooler by an internal fan. The pads of the evaporative cooler and pad are formed of luffa sponge fibers. The cooler may include a device for dispensing antimicrobial and/or antifungal agents into the water reservoir of the cooler. Alternatively, the pads may be pretreated with antimicrobial and/or antifungal agents. A cooling fan is provided in the interior of the cooler to blow cooled, humidified air over the surface of the water in the reservoir before the water is passed through the evaporator pads, thereby increasing the cooling efficiency of the system.

First claim

I claim:

1. A refrigerator comprising: An evaporative cooler and pad, comprising:
a hollow housing having at least one porous wall and an outlet, the housing defining an interior volume;
a porous evaporator pad disposed within the housing immediately adjacent the porous wall, the porous evaporator pad consisting of a plurality of sheets of luffa sponge fibers;
wherein the plurality of sheets of luffa sponge fibers are compressed together to form a multiple ply porous evaporator pad;
a water reservoir disposed within the housing;
a cooling fan disposed within the housing;
a temperature probe and a thermostat coupled to the cooling fan and sensing a water temperature of the water reservoir;
wherein the temperature probe and the thermostat selectively actuate the cooling fan to blow air over the surface of the water reservoir when the water temperature is at a predetermined level;
a water pump disposed within the housing, the water pump selectively drawing water from the water reservoir and delivering the water to the multiple ply porous evaporator pad;
a motor and a driving fan disposed within the housing, the motor and the driving fan selectively drawing air through the porous wall and multiple ply porous evaporator pad and expelling the air through the outlet;
an agent dispenser disposed within the housing; and
an aseptic agent disposed in the agent dispenser, the agent dispenser being configured for selectively dispensing the aseptic agent into the water reservoir.

2. The evaporative cooler and pad according to claim 1 , wherein the aseptic agent comprises an antibacterial agent.

3. The evaporative cooler and pad according to claim 1 , wherein the aseptic agent comprises an antifungal agent.

4. The evaporative cooler and pad according to claim 1 , wherein the aseptic agent comprises a deodorant.

5. The evaporative cooler and pad according to claim 1 , further comprising a scent disposed in the agent dispenser, the agent dispenser being configured for selectively dispensing the scent into the water reservoir.

6. The evaporative cooler and pad according to claim 1 , wherein the multiple ply porous evaporator pad has a density of 175 milligrams per cubic centimeter.

7. The evaporative cooler and pad according to claim 1 , wherein the multiple ply porous evaporator pad is treated with an antibacterial agent dispersed into the water and delivered onto the luffa sponge fibers.

8. The evaporative cooler and pad according to claim 1 , wherein the multiple ply porous evaporator pad is treated with an antifungal agent dispersed into the water and delivered onto the luffa sponge fibers.

9. The evaporative cooler and pad according to claim 1 , wherein the multiple ply porous evaporator pad is treated with a deodorant dispersed into the water and delivered onto the luffa sponge fibers.

10. The evaporative cooler and pad according to claim 1 , wherein the multiple ply porous evaporator pad is treated with a scent dispersed into the water and delivered onto the luffa sponge fibers.

11. A method of manufacturing a porous evaporative pad for an evaporative cooler, the evaporative cooler including:

a water reservoir disposed within the housing;
a cooling fan disposed within the housing;
a temperature probe and a thermostat coupled to the cooling fan and sensing a water temperature of the water reservoir;
wherein the temperature probe and the thermostat selectively actuate the cooling fan to blow air over the surface of the water reservoir when the water temperature is at a predetermined level;
a water pump disposed within the housing, the water pump selectively drawing water from the water reservoir and delivering the water to the multiple ply porous evaporator pad;
a motor and a driving fan disposed within the housing, the motor and the driving fan selectively drawing air through the porous wall and multiple ply porous evaporator pad and expelling the air through the outlet;
an agent dispenser disposed within the housing; and

an aseptic agent disposed in the agent dispenser, the agent dispenser being configured for selectively dispensing the aseptic agent into the water reservoir;
wherein the method consisting of the step of:
assembling a plurality of plies of luffa sponge fiber sheets together in a range from two to four sheets of luffa sponge fiber sheet, thereby forming the multiple ply porous evaporator pad;
compressing the multiple ply porous evaporator pad of luffa sponge to a density of 175 milligrams per cubic centimeter; and
trimming the compressed, multiple ply porous evaporator pad of luffa sponge, thereby forming the multiple ply porous evaporator pad for an evaporative cooler;
selecting at least one agent from the group of additives consisting of bactericidal, fungicidal, and deodorant agents; and
applying the at least one selected agent to the multiple ply porous evaporator pad.

12. An evaporative cooler and pad combination for cooling air, the combination comprising:
a porous evaporator pad;
the porous evaporator pad consisting of a plurality of two to four sheets of luffa sponge fibers, the plurality of sheets of luffa sponge fibers are compressed together to form a multiple ply porous evaporator pad having a density of 175 milligrams per cubic centimeter; and
a cooler;
