Abstract

The cleaning attachment (10) for use with a water hose (14) includes an angle adapter (20), a water control valve (30), a quick connect coupling (40, 42), a first thread adapter (60), a debris screen, a second thread adapter (70), a compression fitting adapter (80), and a hollow wand (90). The cleaning attachment (10) is designed to act as a nozzle for directing and dispensing water from a conventional water hose (14). Specifically, the cleaning attachment (10) is designed for effectively cleaning air conditioner coils, particularly condenser coils and evaporator coils. Cleaning attachment (10) allows a user to clean a coil with a flow of water through openings in the coil, eliminating the conventional need to disassemble the coil. The cleaning attachment (10) may also be used for a variety of other purposes for which a flow of pressurized water is needed.

Claims

1. A cleaning attachment for use with a water hose, comprising:

a water control valve having opposed female and male ends, the female end being adapted for releasable connection to the water hose;

a first threaded adapter having a female end for releasable connection to the male end of the water control valve, the first threaded adapter having an opposing male end, the male end having external pipe threads;

a second threaded adapter, the second threaded adapter having a first female end releasably attached to the male end of the first threaded adapter, and an opposing second female end having internal pipe threads;

a hollow wand having opposed first and second ends, the second end of the hollow wand being closed, the wand having an aperture formed therein adjacent the closed second end forming a spray outlet; and

a compression fitting attaching the wand to the second female end of the second threaded adapter.

2. The cleaning attachment as recited in claim 1, further comprising an angle adapter having a female connecting end and a male connecting end, the angle adapter being releasably connected between said water control valve and the water hose.

3. The cleaning attachment as recited in claim 2, wherein the male and female connecting ends of the angle adapter are each threaded.

4. The cleaning attachment as recited in claim 1, wherein the male end of the water control valve is selectively rotatable axially with respect to the female end thereof.

5. The cleaning attachment as recited in claim 1, further comprising a quick connect coupling disposed between the water control valve and the first threaded adapter.

6. The cleaning attachment as recited in claim 5, wherein the quick connect coupling includes a female member and a male member, the female member having a first end for receiving the male end of the water control valve and a second end for receiving a male quick connect extension of the male member, the male quick connect extension of the male member being formed at a first end thereof, the male member further a second end having external hose threads.

7. The cleaning attachment as recited in claim 6, further comprising a debris screen disposed between the first threaded adapter and the male member of the quick connect coupling.

8. The cleaning attachment for use with a water hose as recited in claim 1, further comprising a debris screen disposed between the first threaded adapter and the male end of the water control valve.

9. The cleaning attachment for use with a water hose as recited in claim 1, wherein said hollow wand is elongated and has a substantially linear contour.

10. A cleaning attachment for use with a water hose, comprising:

a water control valve adapted for releasable connection to the water hose;

a hollow, elongated wand having a closed end and a nozzle opening formed therein adjacent the closed end;

a compression fitting disposed between the wand and the water control valve; and

a mesh screen disposed between the water control valve and the compression fitting, the water control valve, the compression fitting, and the wand forming a water conduit for delivering water from the water hose in a spray from the nozzle opening, the mesh screen filtering particulate matter from the water before delivery to the wand.

11. The cleaning attachment according to claim 10, further comprising at lease one threaded adapter disposed between said water valve and said compression fitting for adapting thread types and fitting sizes.

12. The cleaning attachment as recited in claim 10, further comprising an angle adapter disposed between said water control valve and the water hose.

13. The cleaning attachment as recited in claim 10, wherein said water control valve comprises a swivel valve rotatable axially by about 360°

.

14. The cleaning attachment as recited in claim 10, further comprising a quick connect coupling disposed between said water control valve and said compression fitting, the quick connect coupling being axially rotatable by about 360°

.

15. The cleaning attachment as recited in claim 14, wherein the quick connect coupling includes a female member and a male member, the female member having a first end for receiving the male end of the water control valve and a second end for receiving a male quick connect extension of the male member, the male quick connect extension of the male member being formed at a first end thereof, the male member further a second end having external hose threads.
