Abstract

A drain unblocking and cleaning device comprises, between the initial tube section with an initial end (11) and the drain trap (12), a mechanism (2) opening and closing the flow passage, which comprises a central tube section (22) with a wider diameter than the initial tube section (11), a floating element (21) that is located inside the central tube section (22) and allows, in the rest position, the flow through the initial section (11) and the drain trap (12), an opening (23) in the tube section (22), through which a flow from the sanitary water network is allowed to enter through a flexible pipe (3), in such a way that when the drain trap is clogged and no flow is possible therethrough, the pressurized water entering through the opening (23) pushes the floating element (21) upwards (blocking position), plugging the initial section (11) of the drain duct and preventing the sanitary water from returning to the sinkhole (5), and at the same time, with the force of the pressure applied, it pushes any waste out of any other section of the drain duct (1), in particular out of the drain trap (12).

Description

DESATASCADOR AND DEPARTMENT CLEANING DEVICE

OBJECT OF THE INVENTION

The invention, as expressed in the statement of the present specification, refers to an unblocking and drain cleaning device that provides, to the function to which it is intended, advantages and characteristics, which are described in detail below, which assume a remarkable novelty in the current state of the art.

The object of the present invention lies in a device designed specifically for the maintenance and cleaning of all the components of a drainage pipe, especially the siphon they usually have, which bases its operation on the use of the force of the pressure exerted by the water channeled into the building's own network which, through the corresponding installation, is injected in a controlled manner through a hole of said device on a mechanism for closing and opening the passage of the fluid, avoiding any need to disassemble any part of the drain.

FIELD OF APPLICATION OF THE INVENTION

The field of application of the present invention is part of the industry sector dedicated to the manufacture of plumbing installations for water evacuation, focusing particularly on the scope of applicable devices to facilitate cleaning and removal of obstacles that obstruct the drainage pipes of said facilities. BACKGROUND OF THE INVENTION

As the closest document, it is worth mentioning that the Spanish patent ES1026751 U is known which describes a system for the unblocking and cleaning of drains and their ducts, consisting of inserting a basic element, as a cylindrical or prismatic body, which is inserted in the duct of drainage of definitive form but removable with an inclination of 45 ° and in a position later to the own siphon of the drainage. Accordingly, the device influences only the unblocking of the drain pipe but not the siphon. In addition, according to the description of the same, nothing is mentioned that suggests that it also cleans the drain siphon itself since, as noted, the cylindrical body is placed in the drain pipe after the siphon, so the eventual action Water cleaning is prevented by the cylindrical body itself whose essential characteristic is to prevent the return of water in the opposite direction to the wastewater evacuation circulation. In addition, the system for the unblocking and cleaning of drains known by the Spanish patent ES1026751 U does not contemplate the possibility of adaptation to programming, nor control by remote control or applications to home automation.

On the other hand, it should be mentioned that mechanical pipe unblocking systems are also known based on introducing springs and or wires of greater or lesser section, manually operated or by motors, to facilitate the rotation of said elements and eliminate the jams, thereby which differ substantially with the present invention.

Likewise, there are inventions that use cylindrical bodies temporarily coupled to the drainage system that are based on the action of the air pressure injected into the manual pipe, mechanically or by the action of an engine. The rest of the unblocking and cleaning systems of the drain pipes are based on the use of chemical agents introduced through the drain and that also have nothing in common with the device presented here.

It can be stated, therefore, that as a reference to the current state of the art, at least by the applicant, the existence of any other plunger and drain cleaning, or other application or device invention, which has characteristics is unknown. technical, structural and constitutive the same or similar to those presented here claimed.

EXPLANATION OF THE INVENTION

The degasser and drain cleaning device proposed by the invention is thus configured as a remarkable novelty within its field of application, the distinguishing details being conveniently set forth in the final claims that accompany the present description.

More specifically, what the invention proposes, as indicated above, is a device specially designed for cleaning and maintenance of all the components of the drainage channel in which it is incorporated, especially that of the siphon, for which it bases its operation in the use of the force of the pressure exerted by the water channeled into the building's own network that is injected in a controlled manner through a hole on a spherical mechanism for closing and opening the passage of the fluid from the device. Thus, the essential objective of the present invention is to provide a system of unblocking of all the components of a drain, both of the siphons and of the pipes, since, in view of the prior art, there is still a need for said system.

It is further the object of the present invention to provide a drain cleaning system and a solution to eliminate the jams produced by the accumulation of particles and other substances such as foodstuff remains, paper, hairs, etc. that can be found regularly or not in the ducts of a drain.

It is yet another object of the present invention to provide a drainage and drain cleaning system that is highly efficient, simple, simple to use, at low cost, and without the use of chemicals.

It is yet another object of the present invention to provide a drain and drain cleaning system that provides a manually operated means by means of a timed shut-off tap without the need of an electric battery and that its programmable automatic operation is also possible, with or without remote control, in addition, that its connection via wireless (wireless) for home automation applications is also possible in such a way that the opening of the network water flow valve is activated periodically and cleans the drain avoiding the formation of jams.

It is yet another object of the present invention to provide a drain and drain cleaning system that uses in a simple manner, and without the addition of any external agent to the installation, the mains water and the power of its own existing pressure in the installation . It is yet another object of the present invention to provide a drainage and drain cleaning system that is highly ecological and that does not negatively impact the ecosystem, that does not emit toxic gases into the atmosphere and does not contaminate aquifers.

It is yet another object of the present invention to provide a drain and drain cleaning system that saves water consumption, which is such a precious and necessary element to preserve, since it is possible to install a timed valve in the mains water supply. Close the water flow automatically.

It is yet another object of the present invention to provide a drain and drain cleaning system that is adapted for use by all users, even people with some physical or psychological disability and that does not imply a possible risk of poisoning from the use of chemical products. , and at the same time that does not require the use of physical effort.

And finally, it is another object of the present invention to provide a drain and drain cleaning system that does not require disassembly of the reservoir, sanitary apparatus, and which in turn is self-cleaning. This means a great saving in the cost of specialized labor for its operation.

For all this, the drain and drain cleaning device of the invention, which, as said, is designed to be incorporated into a drain pipe in order to unclog and clean said pipe from the siphon to the end that splices with the drain pipe generally located on the floor or wall, it is essentially configured from an opening and closing mechanism of the flow passage that is located between the initial end of the section of the drain pipe, which starts from the sump of the tank and / or sanitary, and the siphon of said drain.

The device, in addition, is connected to the sanitary water network, for the use of the pressure force of said network, by means of a flexo that is connected to the mouth of a hole made in the drain duct in the area in which said mechanism is located, which, preferably, is formed by a floating element, preferably a sphere, housed in a central tubular section of greater diameter of the conduit, preferably spherical or cylindrical, so that when the pressure is actuated of the water directly affects the floating element, having a valve that, with its manual or automatic actuation, allows the opening and closing, as appropriate, of the passage of the sanitary water of the network to clean and unclog the entire drainage system.

This is because the water that penetrates through this orifice drives the floating sphere or element upwards, to the point of union between the spherical or cylindrical central section in which the sphere is housed and the initial section of the cylindrical drain pipe outlet in the drain and prevent sanitary water from returning and at the same time push, with the force of the pressure exerted, the waste that causes the clogging. Once the valve for closing the passage of the sanitary water of the network is activated, the floating sphere will return to its neutral position inside the spherical or cylindrical section of the tube, leaving the passage of the drain free.

All tests were carried out with drains of a standard domestic sink formed by a drain of a standard diameter of 1½ inches, a pipe adapted to such a vertical drop sump, where the mechanism of this invention will be connected by means of a threaded element up to a siphon or an "U" elbow, followed by a flexible pipe adapted to any angle, also joined by means of thread or glue, to reach the horizontal drain pipe. In said tests, the force of the water pressure in the network is used to drive the internal mechanism of the invention, which prevents the return of the water in the drain and in turn to drag the particles and / or substances deposited in both the siphon and in the drain pipe that prevent the action of wastewater evacuation down the drain.

Intentional jams were made with materials so diverse and common that they can be found in the drains of the toilets such as bathtubs, showers, bidets, sinks, toilets, landfills and sinks, coming from food scraps, hairs, cellulose remains, etc. The result of all the tests carried out was 100% satisfactory thanks to the drag power of the water pressure of the network.

Likewise, the described internal non-return mechanism contemplated by the device of the invention, which, as said preferably, is spherical or cylindrical in shape, is intended to be used in industrial pipelines where tank and container drains of various substances can produce traffic jams of varying degrees and levels, partially or totally preventing the drainage of wastewater in the evacuation ducts, with the inconvenience that this entails.

The material with which the device of the invention is constructed can be PVC, metal or other that adapts to the technical and functional requirements of the installation, since it is not of the same nature if its use is domestic or if it is industrial .

For its part, the connections to the drain pipe, the mouth of the water inlet hole of the spherical section of the mechanism and the nut of the sump can be made by means of thread, glued or flanged according to the requirements of the domestic or industrial installation.

The described device for unblocking and cleaning of drains, therefore, consists of an innovative structure with characteristics unknown until now for the purpose to which it is intended, which, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that It is requested.

PREFERRED EMBODIMENT OF THE INVENTION

In view of the described figure 1 and only, and in accordance with the numbering adopted therein, an example of a non-limiting embodiment of the unclogging device and of recommended drain cleaning can be observed, which comprises the parts and elements that They are indicated and described in detail below.

Thus, as can be seen in said figure, the device in question, applicable to be incorporated in a drain conduit (1) of which comprise a vertical initial tubular section with an initial end (1 1), which starts from the sump ( 5) from the reservoir and / or sanitary to which the drain (1) corresponds and from which the flow to drain enters, a central section with a siphon (12) and final tubular section, vertical or horizontal, with a final end (13 ) that splices with the pipe of the general drainage of the installation, is configured essentially from a mechanism (2) for opening and closing the flow passage which, formed by a floating element (21), preferably a sphere, housed in a central tubular section (22) of the drain pipe (1), which preferably has a spherical or cylindrical shape, and is larger in diameter than the floating element (21) and that the initial end (1 1) of the vertical section of the drain line (1) and siphon (12), existed also in said mechanism (2) a hole (23) in whose mouth is connected, by means of a flexo (3), a flow inlet from the sanitary water network which, taking advantage of the pressure force of said network, affects the mechanism (2) in such a way that the penetrating water drives the floating element (21) upwards, plugging the initial section of the drain pipe (2), as can be seen in the representation of figure 1 where the sphere determining said floating element (21) has been represented in said position with dashed lines, and preventing the sanitary water from returning and, at the same time, pushes, with the force of the pressure exerted, the eventual residues of any other section of the drain pipe (1), especially the siphon (12).

For this, the hole (23) of the central tubular section (22), preferably, is located at the rear of the drain pipe (1), thereby avoiding increasing the volume of the set of elements that form the device, and with a orientation pointing upwards, from the lower zone of said central tubular section (22), for example forming an angle (a) of 54 ° with respect to the vertical, such that it determines an inlet of water through which it pushes the floating element (21) upwards from its lower part to facilitate blocking the initial section (1 1) of the conduction. The water inlet can also be horizontal (figure 3), or even with a certain downward orientation, although in that case it should not point to the floating element (21) in its support on the lower part of the central tubular section (22).

The central tubular section (22) is preferably spherical and comprises two hemispherical pieces threaded together. This form facilitates the manufacturing and installation process of the plunger device.

In another preferred embodiment, the central tubular section (22) is cylindrical.

Also preferably, in said water inlet through the opening of the hole (23) of the mechanism (2), the existence of a valve (4) is provided for the closure of the passage of the sanitary water of the network, which, either manually operated or is automatically operated, for example provided with timed closing without electric battery and, optionally, automatic operation with programmable opening and closing. In addition, it is preferably provided that said programmer may be operated by a remote control. Likewise, a version with wireless connection (wireless) for home automation applications is optionally contemplated.

With all this, and following the example of figure 1, the operation of the device is basically the following:

The mechanism (2) for opening and closing the flow passage, comprises a floating element (21) that moves inside the central tubular section (22) of greater diameter of the drain pipe (1), to release the passage of the residual water, in order to prevent the return of the fluid by exerting pressure against the initial end (1 1) and dragging the particles that cause the eventual clogging of the drain pipe (1) from the siphon (12) to the end end ( 13) outlet that connects to the general floor or wall drain.

The mechanism (2) also has, in the central tubular section (22), a threaded hole (23), where the flexo (3) is connected for the sanitary cold water intake of the network in which, likewise, a valve (4) of the same diameter is attached to it to control the circulation of said water.

Said valve (4) can be operated manually, by means of a lever, or by means of a button with a timed closure, thus preventing the flow of fluid from being permanently open and the excessive consumption of water, being able to be incorporated into the global home automation system of the apartment to which the installation of the drain line (1).

The floating element (21) is made of light material and will close the passage of the drain pipe (1) at its initial end (1 1) when it is released by the pressure of the water introduced through the hole (23), towards the vertical section in which said initial end (1 1) of the drain pipe (1) is located, exerting pressure against it when the valve (4) is operated and allows the passage of water under grid pressure, for the function of unblocking or cleaning the siphon and all the elements of the drain pipe (1).

Once the drain pipe seal (1) is released, the floating element (21) is housed in the central tubular section (22) of the drain pipe (1), when the valve is not actuated, returning to its neutral position and usual, thus allowing the normal and desired circulation of wastewater to the siphon (12) to the end (13) that joins the general drain on the floor or wall. For this unblocking function, the intervention of specialized personnel or the disassembly of the sanitary device or any of its elements of the installation is not necessary.

For the purposes of the discussion of the invention described herein, a typical household sink drain comprising the following sections has been taken into account: a vertical one, which has the initial end (1 1) in which it is coupled to the sump through a nut (5), and that is where the mechanism (2) is incorporated at a minimum distance (d) from it, then a U-bend that defines the siphon (12), and a final section which at its end (13) connects with a general, horizontal or vertical drain pipe attached to the floor or wall duct.

In the embodiment of Figure 2, the hole (23) of the central tubular section (22) It is oriented in a plane parallel to the axis of the central tubular section (22). That is, the water inlet direction does not intersect with the axis of the central tubular section (22), so that it impacts on one side of the floating element (21), which would cause it to rotate and help release it from any adhesion or blockage. .

The base of the central tubular section (22) may have irregularities (24), such as projections or ribs, so that the support of the floating element (21) in that base is not total, but allows communication of the central tubular section (22 ) with the siphon (12).

Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any person skilled in the art understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it does not alter, change or modify its fundamental principle .
