The present invention relates to a top-bottom swimming pool pressure cleaner, and, more specifically to a top-bottom swimming pool pressure cleaner including a nose.
Swimming pools generally require a certain amount of maintenance. Beyond the treatment and filtration of pool water, the walls of the pool should be scrubbed regularly. Further, leaves and various debris can float on the surface of the pool water, and should be removed regularly. Swimming pool cleaners adapted to rise proximate a water surface of a pool for removing floating debris therefrom and to descend proximate to a wall surface of the pool for removing debris therefrom are generally known in the art. These “top-bottom” cleaners are often pressure-type or positive pressure pool cleaners that have a source of pressurized water in communication therewith. This source of pressurized water could include a booster pump, for example. Generally, this involves a hose running from the pump to the cleaner head. However, when the top-bottom pool cleaner reaches the water surface, the cleaner may oscillate vertically above and below the water surface impacting the effectiveness of the pool cleaner to adequately clean debris from the surface of the water. Another issue with top-bottom pool cleaners is that a pressure wave located in the front of the pool cleaner can direct debris away from the cleaner. For example, as shown in
Accordingly, there is a need for improvements in top-bottom pool cleaners that are capable of dampening the oscillation of the pool cleaner at the water surface, directing debris into the pool cleaner rather than away from it, and/or providing other advantages.
A top-bottom pool cleaner is provided including a top housing and a nose attached to the top housing. The top housing including an exterior surface and a top surface having a filter. The nose defines a chamber for receiving and retaining water within the nose. The chamber of the nose receives water through the filter when the cleaner is submerged and retains water within the chamber when the cleaner reaches a top surface of the water from under the water surface, the retention of the water within the nose preventing the pool cleaner from oscillating above and below the top surface of the water.
The foregoing features of the invention will be apparent from the following Detailed Description of the Invention, taken in connection with the accompanying drawings, in which:

With reference to
The cross member 40 connects to and spans across sidewalls of the body 38, forming a skimmer opening 56, a channel 58, and a rear opening 60. The skimmer opening 56 is an opening generally at the front of the cleaner 10 formed between the body 38 and the cross member 40 such that the skimmer opening 56 allows the flow of liquid and debris between the body 38 and the cross member 40, along the channel 58, and exiting the rear opening 60. The deck 42, the sidewalls 44, and the cross member 40 provide the structure that forms the channel 58. In operation, when the cleaner 10 is in “top” mode, debris that floats along the water line 16 of the pool 12 would travel through the skimmer opening 56, across the channel 58, e.g., along the deck 42, and out through the rear opening 60 into the debris bag 62 (
A plurality of skimmer/debris retention jets 31 are positioned on each of the sidewalls 44 of the top housing body 38 to spray pressurized water rearward toward the debris bag 62. The skimmer/debris retention jets 31 spray pressurized water when the cleaner 10 is in the skim/top mode of operation. The skimmer/debris retention jets 31 function to force water and any debris that may be in the channel 58 rearward into the debris bag 62. Furthermore, the jetting of water rearward causes a venturi-like effect causing water that is more forward than the skimmer/debris retention jets 31 to be pulled rearward into the debris bag 62. Thus, the skimmer/debris retention jets 31 perform a skimming operation whereby debris is pulled and forced into the debris bag 62. Furthermore, the skimmer/debris retention jets 31 prevent debris that is in the debris bag 62 from exiting.
The chassis 32 includes wheel wells 64, which functions as side walls of the chassis 32 and a housing for the rear wheels 66. The rear wheels 66 are each respectively rotationally mounted to the wheel wells 64. The chassis 32 also includes a front wheel housing 68, which extends outwardly from the front of the chassis 32 and functions to rotationally secure a front wheel 70 to the chassis 32. The front wheel 70, and the rear wheels 66, which are freely rotatable, support the cleaner 10 on the pool walls 14 and allow the cleaner 10 to traverse the pool walls 14.

The top surface 74 includes a chamfered top edge 84, a sloped top portion 86, and a plurality of filters 88. The chamfered top edge 84 and chamfered exterior edge 80 both extend in an annular fashion around the nose 34. The chamfered top edge 84 directly abuts chamfered exterior edge 80 to provide a continuous surface between the exterior surface 72 and the top surface 74. The sloped top portion 86 extends downward from top surface 74. The chamfered top edge 84 and the chamfered exterior edge 80 similarly extend downward in the same sloped incline as the sloped top portion 86. The front exterior portion 82 extends upward from the top housing body 38 to the chamfered exterior edge 80 proximate to the sloped top portion 86. As a result, the front exterior portion 82 has a smaller height than the exterior surface 72. The sloped top portion 86 allows debris to pass over the nose 34 into the skimmer opening 56 through the channel 58 and into the debris bag 62. The sloped top portion 86 prevents the debris from getting stuck at the front exterior portion 82. It should be noted that the nose 34 can be shaped in any fashion known to those of ordinary skill in the art and the present application is not limited to the particular shapes described herein.

The nose 34 can allow fluid to enter the nose water chamber 78 while the top-bottom pool cleaner 10 traverses the bottom of swimming pool 12 or when the nose 34 is otherwise submerged under the water line 16. The nose 34 allows fluid to enter the nose water chamber 78 through the plurality of filters 88 and more specifically through the plurality of conduit gaps 94.
When the top-bottom pool cleaner 10 switches to “top” mode and moves to the surface of the water to clean debris located at the water surface, the nose 34 can retain the fluid that entered the nose 34 while the pool cleaner 10 was in “bottom” mode. The nose 34 retains the fluid by having a nose water chamber 78 that is substantially enclosed on all sides. In the embodiment of cleaner 10 shown, essentially the only place for fluid to exit the nose water chamber 78 is through the plurality of conduit gaps 94 located on the top surface 74 of the nose 34. Although some fluid may inevitably splash out through the plurality of conduit gaps 94, the force of gravity will prevent most of the fluid from exiting the nose 34. Furthermore, the bottom filter wall 90 and the downward filter wall 92 will also help keep fluid within the nose water chamber 78 by preventing splashing of the water when the pool cleaner 10 is in motion.
As discussed above, when the pool cleaner 10 switches to “top” mode and reaches the water surface, the pool cleaner 10 in the prior art would typically oscillate vertically causing the front portion of the pool cleaner 10 to periodically angle above and below the surface water, and prevent the pool cleaner 10 from effectively skimming the pool water line 16 for debris. The benefit of having the nose 34 retain water within the nose water chamber 78 is that when the pool cleaner 10 is in “top” mode and the nose 34 emerges from the pool water line 16, the nose 34 will exert a downward force on the front portion of the pool cleaner 10. This force will dampen the oscillation of the pool cleaner 10 when it reaches the pool water line 16 in “top” mode. In particular, the nose 34 will keep the front portion of the pool cleaner 10 substantially at or near a zero degree angle relative to the pool water line 16 and prevent, e.g., inhibit, the cleaner 10 from oscillating in a upward positive angle relative to the pool water line 16. By forcing the pool cleaner to stay substantially at or near a zero degree angle relative to the pool water line 16, debris located at the pool water line 16 can be directed through the deck 42, skimmer opening 56, channel 58 and into the debris bag 62.
It should be noted that the force generated by the nose 34 is directly proportional to the amount of the nose 34 that is above the water surface. As more of the nose 34 emerges from the water surface, the greater the downward force generated on the front portion of the cleaner 10. Therefore, exterior surface 72 should be of sufficient height to allow nose 34 to be above the pool water line 16 while the cleaner 10 is in top mode. As noted above, while the nose 34 is fully submerged, there is no force generated by the water in the nose water chamber 78.
