Abstract
Abstract An evaporative air cooler including improved means for distributing water through the evaporative pad of the cooler through which air is drawn for cooling, the improved water distributing means comprising a tray-like member having a water inlet arranged to introduce water at an approximate central location on said tray-like member, and a plurality of radially outwardly extending water-flow channels extending between the water inlet location and a peripheral edge portion of the member, the tray-like member being located relative to the evaporative pad such that, during use, water issuing from the water flow channels runs downwardly through the evaporative pad.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
213 words
An evaporative air cooler comprising a cooler body including a top panel and side panels, a cooler pad assembly adjacent at least one of the side panels, a blower which, in use, draws air through said cooler pad assembly, a pump which, in use delivers water to said cooler pad assembly, a motor to operate said blower and said pump, water distribution means comprising a tray-like water distributing member supported with respect to said cooler body adjacent the underside of said top panel and having upstanding ribs defining a plurality of outwardly extending water flow channels, and a wall defining a water receiving area, said water flow channels radiating outwardly away from and sloping downwardly away from said water receiving area and being in water flow communication therewith so that water, when the cooler is in use, flows from said area into the channels and outwardly therealong, a water inlet to said water receiving area, said water inlet being connected to a water delivery line leading from the outlet side of said pump, the relative locations of said tray-like water distributing member and said cooler pad assembly being such that water issuing from the water flow channels runs downwardly over a peripheral edge of the tray-like member and through said cooler pad assembly.
Claim 2
Dependent Claim
213 words
An evaporative air cooler comprising a cooler body including a top panel and side panels, a cooler pad assembly adjacent at least one of the side panels, a blower which, in use, draws air through said cooler pad assembly, a pump which, in use delivers water to said cooler pad assembly, a motor to operate said blower and said pump, water distribution means comprising a tray-like water distributing member supported with respect to said cooler body adjacent the underside of said top panel and having upstanding ribs defining a plurality of outwardly extending water flow channels, and a wall defining a water receiving area, said water flow channels radiating outwardly away from and sloping downwardly away from said water receiving area and being in water flow communication therewith so that water, when the cooler is in use, flows from said area into the channels and outwardly therealong, a water inlet to said water receiving area, said water inlet being connected to a water delivery line leading from the outlet side of said pump, the relative locations of said tray-like water distributing member and said cooler pad assembly being such that water issuing from the water flow channels runs downwardly over a peripheral edge of the tray-like member and through said cooler pad assembly.
Claim 3
Dependent Claim
65 words
An evaporative air cooler according to claim 1 wherein said tray-like water distributing member peripheral edge is U-shaped, said water flow channels extending between said U-shaped peripheral edge and said water receiving area, said water inlet being located centrally of said water receiving area, and flanges upstanding from an end of said tray-like water distributing member lying contiguous with the underside of said top panel.
Claim 4
Dependent Claim
53 words
An evaporative air cooler according to claim 2 wherein said cooler pad assembly comprises an evaporative pad convexly curved about its central vertical axis such that its cross-sectional shape is substantially identical to the U-shape profile of said water distributing member, said distributing member locating on the upper edge of the evaporative pad.
Claim 5
Dependent Claim
72 words
An evaporative air cooler according to claim 1 further comprising a downwardly projecting boss integrally formed with the top panel and locating over said water receiving area so as to form therewith a chamber into which water, pumped upwardly through said water inlet, flows before entering said water flow channels, said water receiving area and said boss being circular in shape and the diameters of each of which being approximately the same.
Claim 6
Dependent Claim
47 words
An evaporative air cooler according to claim 4 where said tray-like water distributing member has upstanding circumferentially spaced pin engaging in complementary shaped sockets integrally formed on the underside of said top panel so as to fixedly locate said water distributing member relative to said top panel.
Claim 7
Dependent Claim
40 words
An evaporative air cooler according to claim 1 wherein the wall defining said water receiving area has a portion thereof which slopes downwardly away from the water inlet and merges smoothly with the bottom walls of the water flow channels.
Claim 8
Dependent Claim
56 words
An evaporative air cooler according to claim 6 wherein the respective lengths and slope of those said water flow channels radiating approximately towards the rear of the cooler body are respectively less than and greater than the lengths and slope of those said water flow channels which radiate approximately towards the sides of the cooler body.
Claim 9
Dependent Claim
54 words
An evaporative air cooler according to claim 1 wherein said water flow channels radiate away from said area around most but not all of its periphery, and wherein alternate said ribs terminate at their radially inner ends a slight distance shorter than their adjacent ribs and have their ends sloping to form ramp surfaces.
