Description

Technical field

[0001] The present application describes a input device water applicable for example in filtration equipment for water reservoirs, especially swimming pools.

Background

[0002] The water filtration system of a swimming pool or water tank is composed by a set of devices whose main function consists on the cleaning and treatment of the water. The preferential equipment for introducing water into the system is usually called skimmer, which allows the introduction of the water through an orifice or mouth usually placed in the reservoir or pool wall.

[0003] In turn, the water will follow several steps of filtration and treatment until returning inside the pool or tank of water. The skimmer is placed on the top of the walls of the tank or pool as a preferential point of entry of the water into the filtration system.

[0004] Currently, the market offers various types of skimmers. For example, the document FR 0760061 presents a skimmer comprised by two independent parts, fixed in a swivel way. This skimmer presents a flat bottom surface of the water entrance area on the pool side, where the water stagnates, causing a loss of pressure during the suction. The mouth tends to be parallelepiped until the entrance of the body of the skimmer. On the other hand, the now disclosed device presents a descending platform to the body, with an inverted funnel shape. The mouth does not allow the water mirror effect because of its wide lips, with a low covering waterline.

[0005] The document EP 2453078 describes a skimmer with a funnel shape entrance for the conduction of the water of the reservoir, connected to the water inlet which in turn is connected to the filter system and body of discharge, however, it doesn't provide a descending platform until the entrance of the skimmer body, which implies a lower possibility to obtain a water mirror effect on said platform.

[0006] The document AU2009245820A1 describes a filtration system with a water inlet at the top and a compartment which includes at least one chamber that includes a pump and a filter. The filter may include a pair of side by side chambers parts, one of which carries the pump and the other carrying the main filter with water from the first chamber to be pumped into the other chamber by a pump. The shape of the inlet water of the state of the art installation is parallelepiped which serves two chambers simultaneously, which involves a loss of efficiency of entry of water. This is a device with different functionality of the now disclosed device. Thus, the now presented device has an inverted descending trapezium and does not include any pump. Furthermore it only has one chamber which is intended for suction and has an adapted shape of an inverted funnel. Current skimmers present a standard aspect, such as their inlets, presenting performances that are closely related to the design of said parts.

[0007] The present application, in turn, discloses a device which allows to obtain an uniform suction of the water without compromising its aesthetic side.

Description of the embodiments

[0024] The input device (1) for water filtration equipment, especially if used for water tank, particularly for swimming pools, presents its own configuration, whose entrance on the side of the pool or reservoir presents an expanded and flattened rectangular shape, and whose tunnel (17), shaped like an inverted, adapted and descendent funnel, is attached to the skimmer body (15), becoming a single piece, the said equipment designed skimmer. The present device can also further comprise a locking ring (2).

[0025] Seen in profile, the bottom of the tunnel (17) of the input device (1) for water filtration equipment for swimming pools or water reservoir is shaped as a stylized horizontal "S" and the upper side of the tunnel presents a flat surface. That means, in profile, the tunnel (17) of the input device (1) for water filtration equipment for swimming pools or water reservoir is presented with an narrower entrance on the side of the pool or tank than the exit part of the tunnel (17) of the input device (1) for water filtration equipment for swimming pools or water reservoir, on the skimmer body (15) side, allowing their coupling and docking, thereby forming a skimmer.

[0026] The configuration and adapted shape of the tunnel (17) of the input device (1) water for filtration equipment for swimming pool or water tank maximizes the entrance of the water into the skimmer body (15), because of its inverted funnel shape with a descending platform to the skimmer body entrance (16) and therefore inside the filtration system, allowing gains of efficiency of water filtering. The shape of the tunnel (17) tend to present a constant section. The increasing of the height of the skimmer body entrance (16) compensates the tightening of the input device (1) on the water pool or reservoir entrance side, in order to keep the sections of water passage more uniform through the water path in the tunnel (17), enhancing a flow of water at a constant speed, reducing pressure losses and stagnation of water and consequent accumulation of foam and dirt. If lower is the variation of the section, smaller will be the change of water flow speed.

[0027] Furthermore, the entrance of the input water device (1) to the filtration equipment, on the pool or tank side, has an adapted configuration which enhances the suction efficiency because it covers a bigger surface of water compared to the standard models, with significant gains of suction of usually more stagnant areas, such as the corners of the pool or the cleaning of the water line. The adapted rectangular and expanded configuration of the input water device (1) side of the reservoir is flattened on the water surface. The suction of water is more efficient because the device configuration (1) has a larger area of influence / scope of water compared to the mouths of existing skimmers. By increasing the coverage area/influence, the speed of suction tends to be more constant, fostering a less turbulent and more gentle aspiration with gains of sensory comfort to obtain a "Current calmer" sensation near the entrance of the input device (1).

[0028] The input device (1) for water filtration equipment for swimming pools or water reservoir has a configuration that enhances the flow of water into the skimmer body (15), reducing areas of stagnant water with the consequent formation of algae, because of the reduced size of the tunnel (17) and the steep slope on the inner area and the bottom of said tunnel (17), when compared to prior art devices, resulting in lower load loss of water compared to the mouths skimmers on the market. The slope seeks to maintain a constant section throughout the tunnel (17) of the input device (1). The bottom of the tunnel (17) of the input device (1) for water is descending, attending to the form of stylized and horizontal "S", and the inverted funnel, through which the water flows to the skimmer body (15). With this new configuration, there is less stagnant water with consequent reduction of algae formation.

[0029] Furthermore, the configuration and elements that compose the input water device (1) allows to obtain a optimum glass of water effect, because it allows to get higher the water pool level at a higher elevation, due to the low relief of the mirror (4) or outer finishing rim (3), and the inside flap (13) and outside flap (14), getting the water level closer to the edge of the pool or water tank. The input water device orifice (1) for filtration equipment merges the aesthetics of the pool, being discreet, following the water line, in contrast to existing models that require the display of an entrance unsightly and less efficient aspiration. The input water device (1) for filtration equipment for pools or water tank presents an adaptive configuration to prior art skimmer body (15). The input device (1) comprises the thickness of the device (1) of the side of the tank, to which the mirror frame (4), outer rim finishing (3), inside flap (13) and outer flap (14), and that turn, reproduce the effect "low relief / thickness".

[0030] The input water device (1) for filtration equipment for swimming pool or water tank is comprised by a tunnel (17) with an adapted and inverted funnel shape, which can be manufactured in metallic material, for example stainless steel, obtained by bending, yielding sharp edges, welded, allowing that the input device (1) is more resistant to bending, compressive and flexural strength and greater resistance to mechanical shocks, thereby improving their storage, transportation and using at the fieldwork and longevity compared to the deterioration of the materials because of the pool or reservoir of water cleaning or treatment products. This input device (1) may also be fabricated of rigid polymeric material.

[0031] The input device (1) for water filtration equipment for swimming pools or water reservoir is further comprised by a set of fastening and bonding accessories, such as an outer finishing rim (3), which may be made by stainless steel or rigid polymeric material; a mirror (4), which may be made by stainless steel or rigid polymeric material; ring seal (6), inside flap (13) on the side of the pool or reservoir and an outside flap (14) on the side skimmer.

Assembly description

[0032] After the completed assembly of the walls (11) of the pool or reservoir, proceed to the union of the input device (1) for water filtration equipment for pool or water tank to the skimmer body (15).

[0033] The union is made by the placing of the seal ring (6), pre-drilled and with adhesive face to the outside flap (14) on the side of the skimmer and the skimmer body entrance (16), avoiding the clogging of its orifices. This flap is intended to improve the fixation, guiding and coupling among the input device (1) for water filtration equipment of tank or pool to the skimmer body (15), allowing the solidarity and stability of the assembly.

[0034] It follows the bolting or gluing, in the case of use of polymeric material, horizontally and in the direction of the skimmer side to side of the pool or tank, which makes the tightening between the outside flap (14) on the side of the skimmer, the ring seal (6) and the skimmer body entrance (16) using mechanical connection, preferably using screws (7).

The wall (11) has a cut previously made in the upper part with the adjusted dimension to fit the input device (1) for water filtration equipment for swimming pools or water reservoir.

[0036] It follows the bolting of the inside flap (13) of the side of the pool or reservoir to the wall (11), previously drilled, in the factory. The screw is done horizontally, towards the interior of the pool or water tank to the wall (11), joining the inside flap (13) of the pool side to the wall (11), using mechanical connection, for example screws (7) in the recessed existing holes of the inside flap (13) on the pool side, obtaining a regular surface to allow the immobilization and fixing of the input device (1) for water filtration equipment for pools or water reservoir to the pool structure, in particular wall (11).

[0037] It follows the immobilization of the PVC screen (12), by tightening the PVC screen or other waterproof coating using seal rings (6), adhesives, pre-drilled on the inside flap (13) on the side of the reservoir or pool.

[0038] Following, the placing of the outer finishing rim (3), preferably of stainless steel, pre-drilled, fixed by screwing or gluing in their respective holes, horizontally towards the side of the pool to the wall (11) pool, putting together, the outer finishing rim (3), sealing rings (6) and PVC screen (12) or other waterproof coating to the inside flap (13) on the side of the pool, causing the tightening of all these elements and ensuring the tightness. It is used a mechanical connection, preferably screws (7), to enable the fitting of the recessed holes existing in the outer finishing rim (3), obtaining a smooth surface for subsequent placing of the mirror (4).

[0039] It ends with the placing of the mirror (4), with an "U" profile by clipping, preferably stainless steel.
