Abstract

This invention provides a manual, self contained, portable, low voltage electric pool cleaner which draws its power from a surface mounted rechargeable battery. The invention uses pressurized water from a unique pump recirculating system to produce a powerful suction effect necessary for debris removal by an integral filter. All components are submersible except for the power source, which is either handle mounted, or attached to a belt harness worn by the operator. This arrangement precludes the need for external wiring and hoses, thus making the invention a truly portable pool cleaner.

Claims

1. A portable, self-contained pool cleaner comprising:

a) a suction chamber adapted to be placed adjacent to and moved along a submerged surface, said suction chamber converging from a bottom opening to a top opening thereof;

b) an elongated handle having a first end thereof pivotally connected to the suction chamber for manually manipulating the cleaner by grasping an operating end thereof from above the surface of the water in the pool;

c) a tubular, converging suction nozzle having a smaller end and a larger end in fluid communication with the top opening of said suction chamber, said suction nozzle being curved between the smaller and larger ends thereof;

d) a nozzle chamber in which said suction nozzle is enclosed;

e) a converging pressure nozzle within said nozzle chamber having opposed large and small ends, the small end of the pressure nozzle extending into the suction nozzle;

f) a pump chamber having an inlet and an outlet;

g) a submersible electric motor and pump associated with said pump chamber;

h) a first conduit coupled between the pump outlet and the large end of the pressure nozzle;

i) a filter;

j) a second conduit coupled between the smaller end of the suction nozzle and the filter, said second conduit further including a side opening;

k) a third conduit coupled between the side opening of the second conduit and the pump inlet;

l) a screen between the suction nozzle and the pump inlet for controlling debris flow to the filter; and

m) a power source for said electric pump motor.

2. The pool cleaner of claim 1 wherein said pump is a multi stage pump system.

3. The pool cleaner of claim 1 wherein said power source is low voltage DC electricity.

4. The pool cleaner of claim 3 wherein said low voltage DC electricity source is a rechargeable battery and a switch mounted at the operating end of the said handle.

5. The pool cleaner of claim 3 wherein said low voltage DC electricity source is a rechargeable battery and a switch mounted on harness worn by the operator above the water level.

6. The pool cleaner of claim 1 wherein said filter is a disposable filter element.

7. The pool cleaner of claim 1 wherein said filter is irregular in shape and made of permeable material.

8. The pool cleaner of claim 1 wherein said suction chamber has adjustable openings.

9. The pool cleaner of claim 1, further including means of supporting the entire cleaner.

10. The pool cleaner of claim 9 wherein said means of support are plastic wheels mounted to a bottom edge of said suction chamber.

11. The pool cleaner of claim 9 wherein said means of support are sleds of open tubular conduit mounted to a bottom edge of said suction chamber.

12. The pool cleaner of claim 1 wherein said pump chamber, said nozzle chamber, said suction chamber, said suction nozzle, said pressure nozzle, said first conduit, said filter and said second conduit are made of plastic.

13. The pool cleaner of claim 1, further including a waterproof bulb lamp powered by the same source of electricity that powers said pump.
