AU2021103331A4 - Cleaning Device Incorporating A Water Jet Facility For The Removal Of Particulates From Water Features - Google Patents

Abstract

Page ABSTRACT The present invention describes an apparatus for the purpose of removing particulates from the shell, base, and steps of any swimming pools, plunge pools, spas, hot tubs, fountains, ponds, and any garden water features. The unit is designed for the cleaning of leaves and small debris including stones from the abovementioned Water Features. In addition, it is designed for the removal of particulates both in the suspension of and on the surfaces of water features. To collect debris, the Invention uses a solid cylindrical chamber through which the debris passes. A high-pressure jet or jets are located at or over the the leading or front edge of the Main Chamber. When high-pressure fluid is injected through those jets at high velocity into the streamlined Main Chamber through those rear facing jets, this causes a static volume of fluid held within the Main Chamber to instantly drop in pressure. The Pressure Differential creates a flow into the device from the fluid immediately outside and adjacent to the surroundings of the inlet opening of the Main Chamber. That external fluid has a natural higher pressure, to the lower pressure created in the Main Chamber. This flow draws debris into the device and the flow continues to the rear outlet of the device. The principle for creating the flow for this device is not a siphon or a fluid wash methodology, but it is the use of the principle that when high velocity pressurised fluids are injected into contained static volumes of fluid as found in the cylindrical Main Chamber of this device. This device is designed to be used in any depth of a water feature including the cleaning debris from the base, particulates held in suspension, and from the surfaces of water features. Surface collection is possible since the device can be operated in an inverted or angled position without alteration to the original design or configuration of the device. Additionally, the design of the device allows for debris to be collected from the steps, acute corners or shallow areas of water features. The unit is designed to operate in depths of fluid where the water jets at the inlet to the Main Chamber are submerged. This means that the device can be operated in very shallow water features. Due to the efficiency of the principle used, the device will not only remove dirt, leaves, and other debris common to water features but will also collect items 31Page including but not limited to solid items such as stones, pebbles, coins, and pieces of glass. Water or fluid is delivered to the device by connecting a garden hose or hose to the Water Jets through a Water Input Pipe. The Water Input Pipe can serve as a Handle with the high-pressure water flowing through the Handle to the jets. The Handle to which the hose is connected may be of tubular construction, or of multi part, or telescopic in nature. The flow of water and subsequent rate of collection of particulates being collected in the filter container or collector can be varied by controlling the flow of water produced at the water jets. This flow can be controlled by altering the hose water pressure by way of the hose faucet or by incorporating a water pressure control unit in the hose line. AS previously detailed the design of the device permits for the use of common pool type telescopic, and fixed handles/shafts. A garden hose adaptor is incorporated in these units, and one of these can be used as an interface to the device's Water Input Pipe which feeds water to the jets of the device. A Pool Pole can also be used in conjunction with the device. An interface tube with a Pool Pole holder can be located at the rear of the Main Chamber for this purpose. Further, a Pool Pole Holder can be mounted at any convenient point on the Main Chamber. As the unit can be inverted or used at any attitude to maximise cleaning capability, the retention of debris in a collection unit (collection bag, sock, debris cartridge, etc) is assisted by a secondary water jet. This is a small diameter tube that extends from the high pressure water/fluid delivery section of the device to the end of the rear section of the Main Chamber. This secondary jet assists in the flow of debris from the chamber into the collector at the rear of the chamber and assists in eliminating the "back flow" of debris back into the Main Chamber. 19 P a g e 1.8 FIGURE 3 1.1 0 O 1.9 FIGURE 4 1.1 1,56 1..10 1.7 1.3

DESCRIPTION

Background of this Invention

Swimming Pools, Plunge Pools, Spas, Hot Tubs, Fountains, and Ponds including garden water features, whether indoor or outdoor, are hereinafter described as "Water Features". These Water Features present the owner with issues relating to cleaning and maintenance. A major problem is keeping various particulates - such as leaves debris and dirt out of these Water Features. There are numerous examples of pool cleaners; some of these are automatic and many are manual. Typically, in an automatic system an external Pump and Filter unit is attached to a pool type hose. The hose is then attached to some type of immersible cleaning device which will automatically traverse the shell, base, side (and steps) of the Water Feature. The suction action created by the pool pump may be used to vibrate and automate any random or programmed movement of the skimmer head thus assisting in the cleaning process. As the Skimmer head moves around the Water Feature particulates are captured by the attached vacuum cleaner hose and passed to the external filter system for subsequent disposal. This usually involves removal of particulates from a skimmer box or by the backwash of the pump filter unit. In the case of a manual pool cleaning system a pole and pool hose are normally attached to a different type of skimmer head (standalone) which may be wheeled. The Water Feature is then cleared of particulates by using the pole to manually traverse the skimmer head over the base, sides and steps of the Water Feature. The capture of particulates and their subsequent removal is like that of the automatic system service as detailed above. Both these systems are also commonly used for the limited or minor cleaning of a Water Feature. A separate leaf scoop can be attached to a pool pole and used for the removal of particulates from the surface of a water feature.

More recently self-contained underwater pool cleaning systems have been introduced. These units may incorporate an in-line battery, motor device, and impeller. A filtration system is usually located between the impeller and point of particulate capture. Batteries, if used, may be of a rechargeable or of a

51Page

disposable nature. The motor driven impeller is used to create a direct suction/vacuum of water and particulates, which are normally drawn through an integrated filtration system in which the particulates are captured.

These units can be used as a handheld device for some water features (where the device can be fully immersed), or in conjunction with a pole and be used to meet the cleaning requirements of water features of greater depth.

Most of the abovementioned systems share a common characteristic of having some form of motive power above or underwater and an associated filter facility with a filter unit to trap the particulates. In some instances, this may mean that an impeller and the power source for the impeller are both immersed during use.

The abovementioned automatic, manual and self-contained underwater cleaners may be unsuitable to be used for the removal of particulates floating on the surfaces of Water Features or for the removal of particulates held in suspension of Water Features.

The design and purpose of this Invention is for the selected removal of particulates including but not limited to leaves, debris, and small stones, and sharp objects in the cleaning of the shell, base and step surfaces of both deep and shallow water areas of Water Features. In addition, the design and purpose of this invention is for the selected removal of particulates as previously mentioned, from the fluid surface of Water Features, and of particulates held in suspension in the fluids of such Water Features.

Brief Summary of this Invention

Unlike other pool cleaners as detailed above the design of this Invention does not include any form of electrical motor, booster pump or propulsion by an impeller whether external to a Water Feature or as part of a self-contained underwater unit. The design of this Invention does not include the use of mains power or the use of Batteries, either standard or rechargeable or have any moving parts.

The design of this Invention uses the pressure of water created by a water jet or jets from a Water Inlet Pipe (WIP) to create a flow of water into a Main Chamber (MC). The water flow causes particulates, as described beforehand, to be transferred through the Main Chamber to a collection system located at the other end of the Main Chamber. The principle of the device is based upon the Bernouilli Principle.

A key design feature of this Invention relates to the Main Jets, their nozzle aperture, shape and design. The Main pressure water jets are positioned as an integral component of the Main Chamber but may not necessarily be so. The aperture shape of the main water jets produces a water jet projecting into the Main Chamber at an acute angle. As the jet aperture outlets are in the Main Chamber adjacent to the inlet entrance to the Main Chamber this provides for an improved efficiency for the removal of debris and the collection capability of this Invention. These are the main reasons for the preferred position of the main jet outlets at their location above the Main Chamber inlet entrance. The Main Chamber inlet entrance may be of various shape and/or size.

A further key design feature of this Invention relates to the Secondary Water Jet (SWJ) Pipe and its fitting from the Water Inlet Pipe (WIP) and along the Main Chamber. Pressurised water is delivered from the Water Inlet Pipe to the Secondary Water Jet through the wall of the Main Chamber. The Secondary Water Jet (SWJ) utilises a sealed / waterproof interface to the WIP. The SWJ is of a smaller diameter to that of the WIP having a cross sectional area significantly less than the primary Water Inlet Pipe as well as the Water Jet nozzles. The SWJ is a pipe of a nominal diameter of 1-2mm. The Secondary Water Jet does not necessarily utilise any special nozzle at its inlet end in the

71Page

Water Inlet Pipe or at its outlet end in the Main Chamber and may remain as a clean open cut Pipe. The Secondary Water Jet is designed to assist in the removal of particulates at the exit end of the Main Chamber where this Chamber interfaces to the Collection facility. In addition, the Secondary Water Jet is designed to assist in preventing debris already collected, from returning to the Main Chamber. The Secondary Water Jet may also be part of the Water Inlet Pipe and ingress at any point within the Main Chamber while extending to the rear of the Main Chamber.

The Water Inlet Pipe may utilise Garden Hose Adaptors and Connectors of various types and may provide an interface to solid or telescopic tubing, Poles, Wands, Sprayer Poles or hosing material. This will allow for the use of various length Poles through which the water supply can pass. User Poles of this nature may provide for ease of use when accommodating the cleaning of Water Features of different depths. (For example, Spas, shallow Ponds, and Garden Fountains). In addition, an inline water pressure control device may be included to control the flow of water to the Invention, if not part of a Pole or Wand where such control is already present. This control device may be located between the water supply hose and the user Pole, or as a component of the user Pole, or between the user Pole and the Water Inlet Pipe.

In another aspect, and in addition to the User Pole for the Water Inlet Pipe as detailed above, the Invention may utilise a Pool Pole Holder (PPH). This Holder is designed to allow the use of a standard Swimming Pool Pole and associated fittings. This type of Pole is used by most Swimming Pool Owners for connection to various cleaning accessories. A Pole of this nature may be used with the Invention in conjunction with a water supply hose which is attached to the Water Inlet Pipe through respective adaptors and connectors. A Pool Pole may be mounted to or on the Main Chamber by various methods.

A key design feature of this Invention is that the provision of water to the water jets is from an attached garden or other type of hose. In this way the required operational water pressure for the water jets is provided by the water pressure created by and available to the hose from an associated Water Tap or Faucet or water supply. Such hose water pressure can be varied by increasing

81Page

or decreasing the water pressure created by the opening or closure of the Tap, or by a User Hand Control unit, including but not limited to, an inter hose tap, hose gun, nozzle or wand unit installed between the hose Tap or Faucet, water supply and the Water Input Pipe. Variation in water pressure increases or decreases the flow of water through the water jet(s), which subsequently varies the flow of water through the Main Chamber. This variation assists in the collection and removal of larger particulates including solid matter such as small stones. The Debris Collector facility includes but is not limited to lock ring, clip-on or tied type Collector facilities or bags. The Collector facility may be of various type, size, fabric and grade of mesh and may utilise a zip, or a hook and loop fastener, or an alternative closure to provide ease of use in the removal and disposal of debris. It is located at the end of the Main Chamber. Specialised Collector Bags including but not limited to wire mesh or other metallic type containment mesh may be used for the collection and removal of general broken glass debris or sharp objects from water features so that such debris may be safely collected and removed for disposal.

In another aspect a design feature of the Invention is the inclusion of an Innovative Cartridge Collector for the safe removal of sharp debris including glass debris. The new Cartridge accessory may be of a metallic mesh nature, that may avoid damage to nylon mesh type collectors, and may reduce the damage to pool filters and motors that occur with many standard pool filtration systems.

The poles used in conjunction with this Invention may be telescopic, or of a rigid structure and be of various lengths. For example, a short Pole could be used when the Invention is used for the cleaning of particulates from water features including but not limited to a Spa, Children's pool, shallow Pond, Fountain, or an indoor Water Feature. Use of various length poles attached to the Water Input Pipe with associated Hose adaptors provides for economy and ease of use in the cleaning of many water features. For example, an above ground pool maybe better served with a pole of this type rather than a standard Pool Pole. In configurations of the Invention as detailed in Figures included in the Appendix, the Pool Pole Holder may be attached to the Main Chamber and may be located above or below the Water Inlet Pipe. In addition, it may be part of a cylindrical structure that connects to the rear of the Main Chamber (see Figure 3).

91Page

In another aspect, the rate of flow of water to the Invention and its Water Jet may be controlled by a Tap (Garden, Indoor, etc) as associated with the water supply hose, or by way of a Nozzle, Gun, or Wand used as attachments to standard Garden Hose Equipment. The rate of flow of water to the Invention and its Water Jet allows for the effective use of the device in both deep and shallow Water Features and is dependent upon adequate water from a Garden Tap or alternative Water Supply. Such water pressure equivalent to domestic mains water supply and used by a standard Garden Hose Water Supply is required for the operation of the Invention.

In another aspect, the Invention may allow for the collection of stones, pebbles or small pieces of solid debris if these are of less size than the apertures and diameter of the Collection Chamber and may pass by the Secondary Water Jet in an unimpeded manner. This facility may avoid any potential damage to Impellors or Motors associated with the cleaning and filtration components of standard pool or water feature systems.

In summary, the Invention is a cleaning device for a variety of water features of various depths, requiring only the standard supply of pressured water from a standard garden hose or hose connected to an associated Garden Tap or alternative Tap or Faucet. The Invention does not require any motive or drive power that includes but is not limited to electrical, impellor, rotationally powered devices, pumps, booster pumps, external filtration systems or battery power whether rechargeable or not. The Invention does not utilise any mechanical or moving component such as a valve and is therefore not subject to wear associated with the above powered devices or associated moving parts.

Detailed Description of the Embodiments

The attached detailed descriptionof the embodiments of this Invention includes an Appendix of diagrams and pictures of items which are referred to and made in this description. In addition to the details ofthe base devices detailed (Figures 1, 2, 3, and Pictures) other devices which were detailed in ProvisionalPatent Application Number 2020902007 are also submitted in Figures and pictorially. These devices all exhibit the same embodiments as the base device(s), and only illustratealternate configurationsof the same component items.

The Present Invention is a device which can be used for the removal of particulates from the shell, base, steps and surfaces of water features. These include but are not limited to Swimming Pools, Plunge Pools, Above Ground Pools, Spa Pools, Fountains and other Water Features. In addition, the device can be used in the "spot cleaning" of particulates and for the removal of particulates held in suspension by water features. A key design feature of the Invention is that only water under pressure from an attached Hose, Garden or otherwise, is required for its operation.

Figure 1 depicts a side view of the Invention. The unit comprises two main components. These are a Main Chamber (MC) (1.3), and a Water Inlet Pipe (WIP) (1.1). The Main Chamber and Water Inlet Pipe are preferably cylindrical in shape. Both MC and WIP are solid and may be constructed from PVC tubing, or other material, of suitable durability and dimension. The WIP is constructed of a solid material and may be of the same materials and characteristics as that of the Main Chamber. The inlet or input end of the Main Chamber may be of a flared shape whilst the exit (collector) end is cylindrical in shape.

The preferred dimensions of the main items above and the Water Jets (Main and Secondary) that comprise the device are as follows

MAIN CHAMBER Main Chamber Outside Diameter: from 40mm to 65mm Main Chamber Inside Diameter: from 36mm to 60mm Length of Main Chamber: from 120mm to 250mm

111 P a g e

MAIN WATER JETS Diameter: from 1mm to 5mm Multiple Jets: 2mm gap between jets

WATER INPUT PIPE Water Input Pipe Diameter: from 5mm to 50mm

SECONDARY WATER JET

Single Jet Diameter: from 1mm to 3mm

Alternative Tap or water input adaptors may be used for different applications where the attachment of an alternative style of Hose or where a different type of Tap (for example a domestic water supply Tap) is used. Similarly, single or multi-section tubing, telescopic shafts or other types of shafts or wands may be accommodated.

In another aspect, Figure 2 illustrates the side view of the Invention in cutaway form. By design, this denotes the location of the Main Water Jets at the input area of the Main Chamber, and that of the Secondary Water Jet from the Water Input Pipe and into the Main Chamber.

In another aspect Figure 3 illustrates the Invention with a shaft / pole attached to the Water Input Pipe. This water/fluid carrying shaft/pole transfers water from a garden hose (to which it is connected), or some such supply to the Water Input Pipe and the Water Jets that are integrated into the Main Chamber. (Available Water Pressure of between 40 - 45 psi is suitable for the operation of devices). The Shaft also has the purpose of providing the user with a hand-held control facility when using the Invention to clean various

12 IPa ge

water features. Additionally, it illustrates the Holder and the tubing used for attachment to the rear end of the Main Chamber when a Pool Pole is to be used. The Collector facility (Bag, Sock, Collector Cartridge, etc) is attached at the other end of the Pool Pole Holder. This results in a connected item sequence of Main Chamber / Pool Pole Holder / Collector Facility. If the Pool Pole is not required for a particular cleaning circumstance, then the Collector Facility would be directly connected to the rear end of the Main Chamber in place of the Pool Pole Holder.

In another aspect the rear of the Main Chamber may utilise a curved or lipped shape that may assist in the use of Collector Units, where their attachment to the Main Chamber is by way of a strap such as of a Velcro type. Similarly, the rear of the Pole Holder may also adopt the same style of shape for the attachment of a Collector facility. (Refer - Pictures in Appendix).

The Diagrams (Figures) 1, 2, 3 represent the major components of the Invention and detail the attributes and basic configuration of the system. Alternative configurations which comprise the self-same components of the Invention but are in an alternate positioning or connection to the device are included in attached documentation. (These configurations were documented and included in Provisional Application 2020902007).

In another aspect a Main Chamber Base Plate (1.7) which provides additional strength and protection to the Main Chamber has been designed for the device and is included in attached diagrams of the configuration(s).

In another aspect the Water Input Pipe (WIP) may be constructed of non corrosive material with a diameter of between 5mm and 50mm. In the configuration (Figure 1), single or multiple Main Water Jets may be utilised. The Jet(s) is positioned across the Main Chamber inlet entrance at an acute angle. If a slot comprises the Main Water Jet outlet shape then the preferred slot size is 3mm wide and 8mm in length. (Refer Figure 2).

In another aspect, the device can be configured with a smaller Water Inlet Pipe (Figure 4). This can utilise a variety of connections to the water supply including a hose adaptor, telescopic pole, etc. In this configuration the Water inlet Pipe extends along a groove in the top of the Main Chamber (MC) and to

13 IPa ge

the tip of the entrance to the MC. The Main Water Jets (1.5) are in a slot at the end of the Water Inlet Pipe and direct water at an acute angle into the Main Chamber. The Secondary Water Jet (1.6) runs from the Water Inlet Pipe, over the top of and towards the rear of Main Chamber. It passes through the Main Chamber to direct water at an acute angle, at the rear of the Main Chamber, to assist in the collection of debris in the collection facility and avoidance of any backwash to the Main Chamber.

In another aspect, a special Cartridge Collector has been designed for use in conjunction with the device. This Cartridge fits as a collector at the rear of the Main Chamber. It is a cylindrical unit of solid material that will allow for the collection of sharp objects including but not limited to pebbles, pool tile chips, small stones, and glass fragments. (Debris such as these may cause costly damage to other pool cleaning devices, including pump motors and filtration systems if retrieved) Refer Picture / Figure 19, 20 described as Cartridge Collector.

In another aspect control of the Garden or alternative Tap water and related pressure to the Water Input Pipe may be operated by devices including but not limited to an inline tap, gun, nozzle, telescopic pole or wand. Such inline Control Devices may provide greater ease of use rather than the random and more time-consuming control of a Garden Tap which may be some distance away.

Use of a water flow control unit as detailed above may also be convenient when the Invention is used for the "spot cleaning" of particulates in a Water Feature, and also reduces the volume of water "topping up" that Water Feature. This "topping up" capability is a key function and element in the design of this Invention.

In another aspect, the Invention also performs a water "top up" function of water features whether in use as a cleaning device or not. As particulates are captured in the Collector Unit, water from the Main Chamber passes through Collector Unit thus increasing the volume of water in the Water Feature. The rate of volume increase is in proportion to the volume created by the water flow in the Invention at any given time.

14 I P age

In another aspect, and for convenience, the supply hose to the Water Inlet Pipe may be attached to an operator Pole (Pool or other Pole) when located in the Handle Chamber by using a suitable clip or series of clips such that when the Pole is extended or closed the supply hose runs freely through the attached clips, thus avoiding any tensioning between the Hose and Water Inlet Pipe Adaptor. This also provides further ease of use in the operation of the Invention. In addition, the use of a flexible or extendable type hose including but not limited to a coil or spiral type hose may also be employed between the WIP Adaptor and a water control device thus providing a further facility to support ease of operation.

As previously detailed The Water Inlet Pipe may be attached to its supply hose through a specifically threaded hose adaptor. The adaptor will permit a standard connection to a suitable end connector on the hose and the adaptor can be screw fitted into the threaded Water Inlet Pipe. This provides for a simple and economical replacement of the adaptor if it or its washer becomes worn or defective. Alternative Hose Adaptors may be utilised and may be of different interface to the Water Inlet Pipe (WIP). Normal replacement of the adaptor washer may be made should that be the cause of an adaptor failure.

In another aspect, The Collector Unit or a Filter Bag may utilise connections to the Main Chamber that include but are not limited to a "slide and lock" type fitting as illustrated in respective Figures as attached. In addition, Collector Units may be of various sizes, and utilise a variety of materials and grade of mesh to meet collection requirements. For example, a wire mesh Bag of suitable strength and grade of mesh may be used for the collection of objects and debris. In addition, a Collector Cartridge has been specifically designed which may be used for the collection and disposal of sharp objects, including glass pieces, from Water Features which may avoid the maintenance and repair costs from damage to the Filter Systems of Water Features resulting from the collection of glass pieces and other objects.

CLAIMS RELATING TO THE INVENTION

Claim 1 The device comprises a Main Chamber that is a solid streamlined tube with an opening at each end. Water Jets are incorporated at the entrance end of that Chamber and directed to the rear of that Chamber. This principle of injecting high-pressure water into the static lower pressure water contained within the Chamber causes a pressure differential between the water in the Chamber and water surrounding the entrance to the Chamber. As a result, a flow of water is created from the entrance to the rear of the Chamber. This flow induces debris to enter the Chamber and flow to the rear of the Chamber for subsequent collection and disposal.

Claim 2 The device is applicable for use in any water feature. This includes, but is not limited to, Swimming Pools, Plunge Pools, Children's Pools, Spa Pools, Fountains, Ornamental Pools, and Ponds. Debris can be collected by the device from any water feature provided that the main Water Jets are submerged below the surface of the water in that water feature. This makes the device applicable to water features of very shallow depth.

Claim 3 A Secondary Water Jet is located within the Main Chamber and at the rear end and at the top of that Chamber. The purpose of this jet is to assist in the flow of debris at this end of the Main Chamber and to prevent the back flow of debris from a Collector device that is at the rear end of the Main Chamber.

Claim 4 The device is designed to clean debris from the base, steps, surface and that held in suspension of water features. With its use in an inverted or different attitude the device requires no change in its design or configuration to carry out these functions.
