Abstract
Description
- The present invention relates to swimming pool cleaners and, more particularly, to automatic swimming pool cleaners movable along an underwater pool surface for purposes of cleaning debris therefrom. Still more particularly, this invention relates to debris-collection means for swimming pool cleaners having the flow of water pumped and/or sucked by remote pumps into and through the pool cleaners.
- Automatic swimming pool cleaners of the type that move about the underwater surfaces of a swimming pool are driven by many different kinds of systems. A variety of different pool-cleaner devices in one way or another harness the flow of water, as it is drawn or pushed through the pool cleaner by the pumping action of a remote pump for debris collection purposes.
- Suction automatic pool cleaners are very successful when there is fine debris or debris that become soft in water. This fine debris is sucked up by the cleaner and deposited into a pump basket, or other debris-collection device, and the really fine debris passes into the pool filter. An example of a suction cleaner is disclosed in commonly-owned U.S. Pat. No. 6,854,148 (Rief et al.), entire contents of which are incorporated herein by reference.
- Suction automatic swimming pool cleaners are used in places with much sand and slit. Although suction cleaners can take leafy debris once it has softened in the pool, large debris such as large acorns and hard leafs would plug up a suction cleaner. Suction swimming pool cleaners are also limited to the debris size due to loss of suction if the inlet and/or outlet orifices are widened to accommodate such large debris and of the possibility of large debris clogging the pool pipes.
- Conversely, pressure automatic swimming pool cleaners are very successful when there is large debris such as leaves and acorns, these large debris are pulled off the pool surface by virtue of a venturi effect and arc placed into a debris-collection device, such as a bag, above the cleaner. An example of a pressure cleaner is disclosed in commonly-owned U.S. Pat. No. 6,782,578 (Rief et al.), entire contents of which are incorporated herein by reference.
- With a pressure swimming pool cleaner, the limitation is the opposite to the suction cleaner. In removing very large debris from the swimming pool, a pressure cleaner uses a collection bag. Regardless of how fine the bag is, sand and slit can pass through the bag back into the pool.
- The problem is that most often only one cleaner is used in a pool. Therefore, people have either a suction cleaner or a pressure cleaner. Many swimming-pool builders place a suction cleaner into a pool when it is built. This is because there is no real landscaping around the pool at the time of the cleaner installation. However, just few years later, when trees and bushes have grown up, the debris becomes overwhelming and constantly plugs the suction cleaner.
- Still with the pressure cleaner, no matter how large debris is in the pool, there is always sand and slit from cement and other elements of the surrounding environment. Such fine debris will pass through the debris-collection bag back into the pool. Although some swimming pool pressure cleaners have tails that supposedly whip the debris toward the main drain, in reality such tails only bring the dirt into suspension until it falls back on the pool bottom to start the process all over again.
- Attempts have been made to utilize both a suction power and a pressure flow from remote pumps by the same swimming pool cleaner apparatus.
- Another common flaw of pool cleaners is the debris collector which typically presents certain maintenance difficulties. More specifically, when the cleaner operates as a suction cleaner, the debris collector is typically connected to the hoses. This presents a hindrance to the movement of the cleaner and the hoses. Moreover, such in-line debris collectors are typically located in awkward positions in the pool and are difficult to clean.
- It would have been highly beneficial to a suction-cleaner debris collector which is easy to install and maintain and which keeps the pump basket clear of debris.
- Pressure cleaners are known to use flexible nylon bags typically made from a soft material. They also have a tendency to be caught under the cleaner wheels and be damaged. These bags have to be replaced frequently due to tearing and other damage caused by manhandling and improper installation of the bag, including chemical damage to the material of the bag.
- Furthermore, while flexible bags may trap some fine debris, most of slit and dirt flows back into the pool. Flexible bags are hard to clean due to their collapsible nature. In order to clean the bag, one has to open up a zipper, hook-and-loop or slide-on-T closure. Most often dirt gets logged into these closures making it difficult to clean the closures and the bag.
- In the pool, flexible bags act like sails and are a hindrance to pool-cleaner movement. When the bag is full of debris, the balance is lost and the bag falls over, may get caught under cleaner's wheels and obstructs free movement of the cleaner. Once the bag falls over, cleaning ability of the cleaner is lost, but the cleaner may still attempt to move thereby damaging the bag and making it increasingly difficult to clean or replace the damaged bag.
- It is desirable to have a pressure-cleaner debris collector with an increased debris capacity, easy to install and to clean, which gives the cleaner improved buoyancy, and is durable and long lasting.
- It is an object of the invention to provide an improved swimming pool cleaner overcoming some of the problems and shortcomings of the prior art, including those referred to above.
- Another object of the invention is to provide an improved swimming pool cleaner which is able to successfully remove fine and large debris from the swimming-pool underwater surface.
- Another object of the invention is to provide an improved single swimming pool cleaner which may operate as a suction cleaner or as a pressure cleaner.
- Still another object of the present invention is to provide an improved swimming pool cleaner that is easily transformed from a pressure-cleaner type to a suction-cleaner type or from the suction-cleaner type to the pressure-cleaner type.
- Yet another object of the present invention is to provide an improved swimming pool cleaner that includes a suction-cleaner debris collector which is easy to install and maintain.
- Another object of the invention is to provide an improved suction swimming pool cleaner which keeps the pump basket clear of debris.
- Another object of the present invention is to provide an improved swimming pool cleaner that includes a debris collector with an increased debris capacity yet gives the cleaner correct buoyancy.
- Still another object of the present invention is to provide an improved swimming pool cleaner that includes a debris collector which is easy to install and to clean, and which is durable and long lasting.
- How these and other objects are accomplished will become apparent from the following descriptions and the drawings.
- This invention is an improved swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom. The swimming pool cleaner includes a body having a debris inlet and a debris outlet.
- The inventive swimming pool cleaner includes a rigid debris-collection canister secured to the cleaner body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system. In the inventive swimming pool cleaner the collected debris remain at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister. The rigid canister is shaped to minimize obstructions to the pool cleaner movement in the pool by providing improved buoyancy and limiting entrapment of the cleaner by underwater pool structures.
- In some embodiments when the inventive pool cleaner operates as a suction cleaner, the rigid debris-collection canister has a substantially sealed interior to maintain suction. The canister preferably includes a fine-mesh container connected to the debris outlet and positioned for entrapping debris in the sealed interior. The rigid canister also has a connection to a suction-system hose for passing filtered water thereto. The connection to the suction-system hose is preferably a swivel connection allowing the pool cleaner turn in different directions without twisting the hose. The swivel connection may be of the type disclosed in commonly-owned U.S. Pat. No. 6,733,046 (Rief), entire contents of which are incorporated herein by reference. Any other known connection, of course, may also be used.
- In the suction-cleaner embodiment, the rigid debris-collection canister preferably includes a base portion and a cover portion which is sealingly connected to the base portion. In some of such embodiments the rigid debris-collection canister includes an o-ring gasket seal between the base and cover portions. However, any other suitable seal may clearly be used to achieve the sealed interior for the suction-cleaner rigid debris-collection canister.
- In embodiments where the pool cleaner operates as a pressure cleaner; the rigid debris-collection canister includes a base portion and a cover portion connected to the base portion. The cover portion preferably has a series of apertures for passing filtered water back into the pool. It is preferred that the base portion of the rigid canister has a solid structure to retain fine debris therein. The cover portion may include a fine mesh insert positioned opposite the debris outlet to entrap fine debris such as sand and pollen.
- In preferred embodiments, the rigid canister has a debris-receiving region about the debris outlet and a debris-collecting region extending from the debris-receiving region to the rear of the pool cleaner. The rigid canister is preferably configured such that the debris flow to the rear and accumulate from the debris-collecting region toward the debris-receiving region to fill up the canister substantially uniformly and substantially free of interference with the pool-cleaner operation.
- The base portion preferably includes an L-shaped protrusion extending from a base-portion edge. The cover portion preferably defines an aperture configured to receive the L-shaped protrusion therein, thereby forming a hinge connection between the base and cover portions. It is preferred that the hinge connection is positioned at a forward end of the canister. The canister also preferably includes a retaining latch at a rear end thereof for securely locking the base portion to the cover portion during the pool cleaner operation.
- Preferred embodiments of the inventive pool cleaner further include an attachment mechanism securely locking the rigid canister to the pool cleaner body. The attachment mechanism preferably includes a connector mechanism and a locking mechanism. The connector mechanism is secured to the debris outlet and defines a pair of oppositely-positioned slots. The locking mechanism forms a pair of oppositely-positioned locking projections. The locking mechanism is configured to snap the projections into the corresponding slots of the connector mechanism for securely attaching the rigid canister to the pool cleaner body for operation and to withdraw the projections from the slots for detaching the rigid canister from the cleaner for emptying and pool cleaner maintenance.
- The locking mechanism preferably includes a pair of locking members each including one of the locking projections. Each locking member has a fixed end which is secured to the rigid canister and a free end. In a released state, the locking members maintain the projections in the corresponding slots and when the free ends are pressed toward each other the projections are withdrawn from the slots thereby releasing the rigid canister from the cleaner body. Each of the locking members may include a finger grip at its free end for a simple finger pressing of the free ends toward each other to withdraw the projections from the slots to detach of the rigid canister from the pool-cleaner body.
- Each fixed end of the locking member preferably defines a hole therethrough. A fastener stud extends through the holes of both fixed ends and a canister wall, thereby affixing the fixed ends to the rigid canister. The fastener stud may have a U-like shape and include a gripping wedge extending outwardly substantially perpendicular along each leg of the U-shaped stud and sloping to terminate at the end of the leg. The perpendicular surfaces of the wedges engage an interior surface of the rigid canister, thereby securely mounting the locking mechanism to the rigid canister.
- The connector mechanism may include a pair of corresponding keys, one on each of first and second connector portions. The first connector portion preferably extends from the pool-cleaner body around the debris outlet. The second connector portion may be secured to the first connector portion by interengagement of the corresponding keys which engage by rotation of the first and second connector portions. The second connector portion preferably defines the pair of oppositely-positioned slots.
- The swimming pool cleaner of the present invention provides an important advantage in that it can be interchangeably usable as a suction cleaner for removal of fine debris such as sand and slit and as a pressure cleaner for removal of large and hard debris such as large leaves, acorns and stones.
- One such apparatus is disclosed in co-owned U.S. patent application Ser. No. 12/581,405 (Rief et al.) filed on Oct. 19, 2009, entire contents of which are incorporated herein by reference. This application discloses a single cleaner which is successful is removing both fine and large debris from the swimming-pool underwater surface.
- The swimming pool cleaner of the '405 Rief et al. application can be interchangeably usable as a suction cleaner for removal of fine debris such as sand and slit and as a pressure cleaner for removal of large and hard debris such as large leaves, acorns and stones. The body of this cleaner is adapted at the debris outlet for securement of either a water-suction hose connected to a remote suction system or a debris-collection device entrapping debris and passing water therethrough back into the pool. When the cleaner is used as a pressure cleaner, a venturi-line structure is secured with respect to the body. The body is also adapted at the debris outlet for securement of a removable debris-outlet adjuster configured to reduce the debris outlet for connection to the water-suction hose and further includes a debris-inlet adjuster configured to reduce the debris inlet to adapt the cleaner for use as a suction cleaner.
- In the inventive swimming pool cleaner, the cleaner body is adapted for securement of either a water-suction hose connected to a remote suction system or a venturi-line structure connected to a water-flow line fed by a remote pump such that the pool cleaner is interchangeably usable as a suction cleaner and as a pressure cleaner. A rigid debris-collection is canister secured to the cleaner body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that the collected debris remain at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister. The rigid canister is shaped to minimize obstructions to the pool cleaner movement in the pool by providing improved buoyancy and limiting entrapment of the cleaner by underwater pool structures such as ladders and the like.
