DESCRIPTION OF THE APPLICATION

(9) The description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the disclosure and is not intended to represent the only forms in which the present disclosure can be constructed and/or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the disclosure in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and sequences can be accomplished by different embodiments that are also intended to be encompassed within the spirit and scope of this disclosure

(10) Embodiments of the exemplary system and method provide an automated swimming pool cleaner (hereinafter pool cleaner) that has side intake flaps. The side intake flaps may be used to increase the suction cleaning path width of the pool cleaner.

(11) Referring to FIGS. 1-7, an automated swimming pool cleaner 10 (hereinafter pool cleaner 10) may be seen. The pool cleaner 10 may have a housing 12. Located within an interior of the housing 12 may be a pump 14. The pump 14 may be used to create a vacuum. When the pump 14 is active, the pump 14 creates a vacuum that causes dirt and debris to be sucked into the housing 12 through one or more an intakes 16. It should be noted that the pool cleaner 10 could also be coupled to a pool filtration system. The pool filtration system may be used to generate the vacuum within the interior of the housing 12 to suck up dirt and debris on a floor/wall of the swimming pool.

(12) The pool cleaner 10 may have a first rolling mechanism 18 located in a bottom area of a front section of the housing 12. A second rolling mechanism 20 may be located in a bottom area of a rear section of the housing 12. The first rolling mechanism 18 and the second rolling mechanism 20 may each be formed of a pair of wheels 22, a roller, a combination of the pair of wheels 22 and the roller or similar rolling devices. The pump 14 may be used to power a drive system 24. The drive system 24 may be used to rotate one or more of the first rolling mechanism 18 and/or second rolling mechanism 20. Alternatively, the vacuum generated by pool filtration system may be used to power the drive system 24.

(13) One or more rolling brushes 26 may be located in the bottom area of the housing 12 between the first rolling mechanism 18 and the second rolling mechanism 20. The rolling brushes 26 may be used to stir up and encourage dirt and debris to enter intakes 16 in the housing 12. The drive system 24 may be used to rotate the rolling brushes 26.

(14) One or more intakes 16 may be formed in a bottom section of the housing 12. In the embodiments shown in the FIGS. 1-7, the intake 16 may be formed in a bottom central area of the housing 12. The intake 16 may run along the width of the bottom section of the housing 12. When the pump 14 and/or the pool filtration system creates a vacuum within the housing 12, water as well as any dirt and/or debris may be drawn into the intake 16.

(15) One or more slots 28 may be formed in bottom side surfaces of the housing 12. The slots 28 may be in fluid communication with the interior of the housing 12. In accordance with one embodiment, the slots 28 may extend into and be in fluid communication with the intake 16 which may run along the width of the bottom section of the housing 12. When the pump 14 and/or the pool filtration system creates a vacuum within the housing 12, water as well as any dirt and/or debris may be drawn into the slots 28 and/or intake 16.

(16) Water tends to flow along a least resistant path. Thus, too many slots 28 connected to the vacuum formed in the interior of the housing 12 may make it difficult to maintain a balanced flow. This may result in one or more slots 28 and/or intakes 16 to have a partial loss of suction.

(17) To increase the cleaning path width of the pool cleaner 10 to that greater that a width of the housing 12 but without sacrificing the suction power and reduce degree of partial vacuum, one or more flaps 30 may be coupled to the housing 12. The flap 30 may be formed of a light-weight but sturdy material. In accordance with one embodiment, the flaps 30 may be formed of Polyvinyl chloride (PVC) or other types of plastic. The flap 30 may be configured to force water to go under the flap 30 before it enters the slot 28. By doing so, the water forced under the flap 30 may carry the dirt and other debris under the flap 30 and effectively increase the suction cleaning path width of the pool cleaner 10.

(18) In accordance with one embodiment, the flap 30 may be configured to diverge outward from the slot 28. Thus, the flap 30 may be fan shaped when looking downward on the flap 30 such that a width of the flap 30 increases as the flap 30 extends further away from the housing 12 of the pool cleaner 10.

(19) The flap 30 has an open bottom surface 30A exposing a hollow interior 30B of the flap 30. The interior 30B of the flap 30 may be angled downward. In accordance with one embodiment, the interior 30B of the flap 30 may be angled downward such that a distance above the bottom surface 30A decreases as the flap 30 extends further away from the pool cleaner 10. Thus, the interior 30B of the flap 30 may be wedge shaped wherein the distance between a top surface 30C of the interior 30B and the bottom surface 30A decreases as the flap 30 extends further away from the pool cleaner 10. This wedge shape configuration may help to funnel water towards the slot 28 thereby helping to prevent any partial loss of suction within the housing 12.

(20) Each flap 30 may be attached to the housing 12. In accordance with one embodiment, the flap 30 may have an inlet channel 30D. The inlet channel 30D may extend out from the flap 30. The inlet channel 30D may be dimensioned to be inserted into a slot 28 thereby allowing water to flow under the flap 30 and into the slot 28. The above is given as an example and should not be seen in a limiting manner. The flap 30 may be attached to the housing 12 in other manners without departing from the spirit and scope of the present invention. For example, connecting devices 32 such as rivets, screws and similar devices may be used to secure the flap 30 to the housing 12. The connecting devices 32 may be used alone or in combination with the slot 28. As may be seen in the FIGs., the connecting devices 32 may be used to further secure the inlet channel 30D within the slot 28.

(21) A wheel 34 may be rotatably coupled to the flap 30. The wheel 34 may be used to keep the bottom surface 30A of the flap 30 a minimum distance above the floor/wall of the swimming pool. In accordance with one embodiment, a wheel well 36 may be formed in the interior 30B of the flap 30. The wheel well 36 may be an indentation formed in the interior 30B of the flap 30. In the embodiment shown, the wheel well 36 may be formed in the distal end of the interior 30B of the flap 30.

(22) An axle assembly 38 may be used to rotatably couple the wheel 34 to the flap 30. In the embodiment shown in the FIGs., the axle assembly 38 may be rotatably secured within the wheel well 36. A pair of grooves 40 may be formed within wheel well 36. The grooves 40 may house the axle assembly 38 and allow the axle assembly and hence the wheel 34 to rotate freely within the wheel hub 36.

(23) In operation, as the pool cleaner 10 moves along the swimming pool floor/wall, the wheel 34 may keep the bottom surface 30A of the flap 30 a minimum distance above the floor/wall of the swimming pool. Since the wheel 34 may keep the bottom surface 30A of the flap 30 above the floor/wall of the swimming pool, water may be force to go under the flap 30 before it enters the slot 28. By doing so, the water forced under the flap 30 may carry the dirt and other debris under the flap 30 with it and effectively increase the suction cleaning path width of the pool cleaner 10. Thus, the flap 30 may improve cleaning efficiency by increasing cleaning path width but without sacrificing the suction power and/or a partial loss of suction. The flap 30 may allow for balanced suction through the one or more slots 28 and intakes 16.

(24) The foregoing description is illustrative of particular embodiments of the application, but is not meant to be a limitation upon the practice thereof. The following claims, including all equivalents thereof, are intended to define the scope of the application.
