Problems solved by technology

Problems which are frequently experienced with suction-type pool cleaners are the following:1. Inability of the cleaner to climb the upright walls of the swimming pool in order to perform a cleaning action there.2. Jamming of the pool cleaner in tight spots in the pool, for example against steps leading into the pool; and inability of the cleaner to extricate itself.3. In the case of suction-type pool cleaners which incorporate an oscillating hammer, failure of the hammer to seat properly at either end of its stroke in the valve chamber.
Such failure is generally attributable to particulate matter, for example grass seeds or stone particles, that come to rest on the valve chamber surfaces against which the hammer is designed to seat.
Improper seating of the hammer can distort the suction effects to the extent that pool cleaner can come to a complete standstill.

Embodiment Construction

[0026]The pool cleaners 10 illustrated in FIGS. 1 to 7 and in FIGS. 8 and 9 have many similarities to the cleaner described and illustrated in international patent application PCT / IB2004 / 002338 (=WO 2005 / 038170), to which reference should be made.

[0027]Referring to FIGS. 1 to 7, the cleaner 10 has a cleaner or suction head 12 and a tubular structure 14 which mates, as described in WO 2005 / 038170, with the head 12 to form a composite, elongate body 16. The head terminates at its operatively lower end in a circular foot 18 to which an annular footpad 20 is fitted. The inner extremity of a flexible, annular skirt 22 is fitted over the foot 18 as illustrated. The footpad and skirt are not shown in FIGS. 4 and 5.

[0028]The foot 18 defines an entrance opening 19 leading through an entrance space 24 to an inlet 26 in a cover member 28. Side openings 21 also lead into the space 24. The inlet 26 leads into a valve chamber 30 which is of tapering shape. The chamber has a relatively narrow down...

Abstract

A suction-type swimming pool cleaner having an elongate body formed by a suction head and an elongate, tubular structure extending from the suction head, the orientation of the body being at least partially controlled by arms carrying a float and a connection bracket connecting the arms in a releasable manner to the body, to allow the float to be connected to the body at any selected one of a number of different positions along the body length, the head includes a valve chamber having a wedge-shaped hammer oscillating in the chamber responsive to suction flow through the head, the hammer seating against shoulders in the chamber, the shoulders being partially rebated and partially sloped to ensure that they are flushed clean of any particulate matter which could interfere with proper hammer seating.

Description

BACKGROUND TO THE INVENTION[0001]THIS invention relates to a suction type pool cleaner.[0002]Suction-type pool cleaners are well known and have been in widespread use for a number of years. Generally suction-type pool cleaners are connected by a flexible hose to a suction point, typically a suction inlet at the weir of a swimming pool. The cleaner operates on the submerged surface of the pool and water is sucked through it by the pump of the swimming pool filtration unit.[0003]One particularly popular suction-type pool cleaner has a valve chamber with an inlet which in operation is situated near to the submerged surface and through which a water flow is sucked. The chamber accommodates a valve member or hammer which oscillates under the influence of the suction flow and which directs the flow alternately to one or the other of a pair of outlet passages leading away from the valve chamber to the hose. The resulting variations in momentum of the water flow as well as variations in the...
