This application relates to pool skimmer devices, systems, and methods.
Swimming pools are enjoyed by many for leisure and exercise in both private and public settings. To provide healthy conditions and maximum enjoyment, it is important to ensure that water within a swimming pool remains clean, clear, and free from debris. For this reason, swimming pools generally include circulation and filtration systems that are designed to clean the water.
Many swimming pools accumulate unwanted debris, such as leaves, pollen, seeds, insects, etc., on the surface of the water. Commonly, existing circulation and filtration systems may be ineffective at removing this debris from the water's surface. Accordingly, pool owners frequently and undesirably are required to manually capture and remove debris from the water's surface using a pool skimmer net.
Oil spills in water, such as oceans, seas and lakes, also gather oil on the surface of the water. In addition, many micro-plastics and small plastic particles float on the surface of water. Much of these contaminants are difficult to remove and have large environmental and economic impacts.
In a first aspect, a pool skimmer device is disclosed. The device includes a float harness with floats that are allowed to be vertically positioned, and a funnel positioned at the distal end of the extension body, the funnel comprising a wide opening positioned at the distal end of the extension body and a narrow opening, and a funnel profile extending between the wide opening and the narrow opening, and a coarse basket axial centered beneath the funnel assembly, and a ballast collar centered on the vertical axis, and an exhaust outlet.
The device can include one or more of the following features in any combination: (a) wherein the height of the funnel is self-determined and positions itself to float just beneath the surface of the water, which is 0 to 3 inches in depth; (b) wherein the floats on the harness can be positioned to allow the funnel to be positioned vertically on the funnel assembly to allow maximum movement up and down below the surface of the water; (c) wherein the coarse basket filters coarse debris from the water; (d) wherein the ballast collar keeps the entire device vertically positioned in the water and the floats fully against the float stops and the device bottom at a persistent depth; (e) wherein the floats, ballast, and self-adjusting funnel work together to keep the wide funnel opening at a depth just beneath the surface of the water, which is 0 to 3 inches, and the funnel optimally vertically positioned on the funnel assembly, which allows for the funnel to constantly adjust in non-smooth water surfaces, such as swells, wind-chop, or rough water; (f) wherein the bottom outlet (exhaust) allows water to be pulled through the device; (f) wherein the bottom outlet (exhaust) can be connected to a swimming pool vacuum port or skimmer suction opening so the swimming pool filter and pump can pull water through the device and filter the water, which will be returned to the pool in the normal fashion; (h) wherein an optional water pump can replace the bottom outlet (exhaust) pipe, so that water can be pumped through the device at various rates, such as 4000 gallons per hour, if, for example, a Johnson 4000 bilge pump is used; (i) wherein the optionally attached water pump can pump the water into a filter, such as a 50, 100, 200 micron water filter bag, which can have a four or six inch opening, but not limited to these openings or micron ratings; (j) wherein a filter bag plate can be designed to connect the filter bag to the device through a standard pool vacuum hose; and/or other features as described throughout the application.
The features and advantages of the pool skimmer device, systems, and methods described herein will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. These drawings depict only several embodiments in accordance with the disclosure and are not to be considered limiting of its scope. In the drawings, similar reference numbers or symbols typically identify similar components unless context dictates otherwise. The drawings may not be to scale.
This application relates to devices, systems, and methods that are configured to clean a pool, such as a swimming pool. The devices, systems, and methods may be configured, in particular, to clean debris, such as pollen, insects, seeds, leaves, etc., from the surface of the water in a pool. As will be described in greater detail below, the devices, systems, and methods may be configured to use the surface tension of the water to pull in debris from the surface of the water.
Generally, swimming pools include pool skimmers in an effort to clear the surface of the water from debris. An example of such a skimmer is shown in
The following discussion presents detailed descriptions of the several embodiments of the pool skimmer devices, systems, and methods shown in the figures. These embodiments are not intended to be limiting, and modifications, variations, combinations, etc., are possible and within the scope of this disclosure. As will be discussed in more detail below, these pool skimmer devices, systems, and methods can be used to efficiently and effectively clean the surface of a pool.
The pool system 10 includes a circulation and filtration system 20 configured to circulate and clean the water of the pool 11. Various types of circulation and filtration systems 20 can be used. As illustrated, the circulation and filtration system 20 includes a water pump 21 that circulates water from the pool 11 through various suction lines 25 and return lines 27. The water pump 21 also circulates the pool water through a filter 23.
Example flow of water through the circulation and filtration system 20 of the pool system 10 will now be described with reference to
The pool system 10 also includes a pool skimmer 31. The pool skimmer 31 can be positioned in a sidewall 13 of the pool 11. An example pool skimmer 31 is shown in greater detail in the cross-sectional side view of
The pool skimmer 31 attempts to clean the surface of the water of the pool 11 as the pump 23 pulls water through the pool skimmer 31. The conventional process by which the pool skimmer 31 will be described with reference to
The pool skimmer 31 can include a weir door 37 configured to close the aperture 35. The weir door 37 can comprise a hinged door and a float 39. The float 39 is configured to raise the weir door 37 to close the aperture 35 (for example, such that the top of the weir door 37 is positioned at the surface 5 of the water). When the pump 21 (
Within the pool skimmer 31, the pool skimmer includes a skimmer basket 43. The skimmer basket 43 can be supported by a ledge 41 or other supporting structure within the pool skimmer 31. An example skimmer basket 43 is shown in
Below the skimmer basket 43, the pool skimmer 31 can, in some embodiments, include a float valve 45. The float valve 45 can be configured as a safety device for the water pump 21. If the water gets low in the pool 11, a float inside the float valve 45 can fall down to shut off the pool skimmer 31 such that the water pump 21 only pulls water from the main drains 29 of the pool 11. This can prevent damage to the water pump 21 caused by running the pump dry. In some embodiments, a pool system 10 can have the line to the bottom filter capped. However, there are many installations where this opening is not capped, and a pipe extends to the bottom filter opening. In these configurations, the float valve 45 is available.
Another problem with pool skimmers 31 such as shown in
The upper opening 51 provides an entrance into the skimmer basket 43. The upper opening 51 can have a diameter 55 as shown. Various pool supply manufacturers provide different types of skimmer baskets 43 for different types of pool skimmers 31. Accordingly, the diameter 55 of the upper opening 51 may be different depending on the specific embodiment of the skimmer basket 53. Although the upper opening 51 is described as having a diameter 55, in some embodiments, the skimmer basket 43 (and in particular the upper opening 51) may be non-circular (e.g., square or rectangular). The rim 53 can be configured to engage with the ledge 41 of the pool skimmer 31 (
Additionally, as illustrated, the main body 49 of the skimmer basket 43 (e.g., the sidewalls 57 and or bottom wall 59 can include a plurality of apertures 55 (such as perforations or openings) configured to provide straining functionality for the skimmer basket 43. The size of the apertures 55 can vary depending on the specific embodiment. In some embodiments, the apertures 55 can be replaced with or include a mesh.
The skimmer device can be configured to attach to conventional skimmers (
The skimmer device can be configured independently of the swimming pool's filtration system by attaching the optional water pump and filter assembly to the device (
The skimmer devices self-position the larger opening of the funnel at a depth just below the surface of the water in the pool. When the opening of the funnel is beneath the surface, the water level in the skimmer device may be lower than the water level in the pool. This causes the water to follow the shape of the funnel into the lower part of the funnel and into the basket below.
Floating debris in pool water is trapped within the surface tension of the water. As will become more fully apparent from the following description, when water enters the funnel of the skimmer device, the surface will warp and be pulled into the wide opening, through the narrow opening, and through the attached debris catching coarse skimmer basket. Along with pulling the surface water into the skimmer, all or much of the small floating debris, such as pollen, dust, bugs, small leaves, pieces of deteriorating thermo-pool covers, etc., will also be pulled into the skimmer. The debris that is not trapped in the coarse skimmer basket will also be sucked into the pool filter or the attached filter bag assembly, assuming it is sufficiently small so as to pass through the coarse skimmer basket.
Further, since the debris can be mixed into the water as it flows through the funnel of the skimmer device, it can be temporarily less buoyant and more easily sucked into the filter. The turbulence within the skimmer device helps to force the debris particles through the bottom of the basket. These and other features of the skimmer devices described herein will become more fully apparent from the descriptions of the nonlimiting examples of
In the illustrated embodiment, the skimmer has a float harness 114 that may attach to the device via the float harness collar 106. The float harness 114, has floats 113 that are allowed to freely vertically float, but the height has a ceiling defined by the float stops 116. The purpose of the float harness is to allow the entire device to be suspended in the water at a depth that will allow the self-adjusting height of the funnel 100 to place the funnel at an optimal height on the funnel basket holder 104 funnel assembly.
In the illustrated embodiment, the skimmer device, which can also be seen in
The skimmer device optimally functions when the funnel 100 is positioned just beneath the surface of the water (0 to three inches). The floats 113, self-adjusting funnel 100, and the ballast collar 107 work together to ensure that the funnel 100 is properly positioning itself. In much the same way that a sailboat floats and has thousands of pounds of ballast to keep the boat upright and in the water, the ballast and floats function on the skimmer. When the skimmer is functioning the water level in the device should be lower than the water level in the pool. This causes the skimmer device to want to float, and if there were no ballast, then the device would float and keel over in the water, which will cause the device to fill with air and stop functioning. The ballast collar 107 disallows to skimmer device from floating up and keeling over, even when the device has taken on air. The floats 113 prevent the ballast collar 107 from pulling the entire device under the water. Therefore, the waterline of the device will be somewhere between the top and bottom of the floats 113.
The skimmer has two different water lines: 1. When the skimmer device is not functioning there is less air in the device and therefore more of it will be submerged and it will have a waterline closer to the top of the floats 113. 2. When the device is functioning there is more air in the device, and therefore less of it will be submerged and the waterline will be closer to the bottom of the floats 113.
When the skimmer device is functioning, the optimal position of the large opening of funnel 100 is just beneath the water line of the skimmer device, where it can accept the largest amount of surface water (
When the skimmer device is functioning and the funnel is just beneath the water line of the device, which is the water line of the swimming pool, disturbances on the water surface, such as swells, wind chop, and splashing can cause the funnel 100 to rapidly change vertical position to adjust for the quickly varying water levels. The skimmer device can be configured to adapt to varying water levels using two methods: (1) The floats will naturally try to maintain constant depth, but will have damped oscillations while adapting, which will cause the entire device to raise up and down in the water, but not at the same rate as the turbulence itself, and (2) the funnel will try to position itself just under the surface of the water. So, the skimmer device itself is raising and lowering in the water and the funnel 100 is raising and lowering on the funnel basket holder 104, these variations can cause the funnel to quickly adjust in turbulent conditions. Therefore, there are float stops 116 that allow the floats to be positioned so that the funnel 100 can be optimally vertically placed on the funnel basket holder 104. By optimally, we mean with enough room to travel up and down the funnel basket holder 104 without violently crashing into the groove blocks and breaking the funnel ring 102 tabs off.
The floats 113 are be positioned high enough to allow the skimmer device to be low enough in the water to allow funnel 100 to position itself low enough in the water to be just beneath the water line. The lower the device the lower the funnel can travel. The floats 113 are positioned low enough to allow the funnel 100 to position itself above the water line when the device is not functioning, so that any debris in the device does not float out of the device. In smooth water, the variation of the distance that the funnel 100 travels is low and the length of the funnel basket holder 104 can be relatively short. In rough water, the variation of the distance that the funnel 100 travels is high and the length of the funnel basket holder 104 should be relatively long. In either case, the floats 113 should be used to properly place the funnel 100 midway on the funnel basket holder 104 when the device is functioning, but in such a position that the funnel can raise out of the water when the device is not functioning, as depicted in
The above description relates mostly to the use of the skimmer device in swimming pools. However, the design of this device will allow it to be used in many different bodies of water for many different duties. These include, but are not limited to, the following:
In all these cases the size of the device may vary. For example, in a fish pond the device may only be a foot in length and have a funnel diameter of a couple of inches or so. In the ocean, the device may be 10 s of feet long and have a funnel diameter of a foot or more. The size of the device is determined by the task that it is to perform and the medium in which it is placed.
The foregoing description details some embodiments of the invention. It will be appreciated, however, that no matter how detailed the foregoing appears in text, the invention can be practiced in many ways. As is also stated above, it should be noted that the use of particular terminology when describing certain features or aspects of the invention should not be taken to imply that the terminology is being re-defined herein to be restricted to including any specific characteristics of the features or aspects of the invention with which that terminology is associated. The scope of the invention should therefore be construed in accordance with the appended claims and any equivalents thereof.
