Anti-sedimentation tank for water closet

Abstract

The present invention describes an anti-sedimentation tank for an ecological toilet that uses previously-used water containing organic and inorganic solid and / or semi-solid residues, said anti-sedimentation tank comprising a main body that includes a front wall, a rear wall, a flat bottom and a pair of side walls that jointly define an interior volume; an anti-sedimentation member arranged within the interior space that includes generally inclined walls and a generally concave bottom to increase the entrainment force of the water, thus preventing the adherence to or encrustation on its walls of any solid or semi-solid residue, as well as preventing the formation of sediments; a modification of any kind of washbasin mixer valve that allows the washbasin which is integrated into and / or interconnected with a toilet to be used without having to discharge the toilet tank.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to toilets, and it particularly relates to a toilet anti-sedimentation tank to be used preferably in water-saving systems.BACKGROUND OF THE INVENTION[0002]The concern for achieving a more rational use of water is a matter of increasing relevance worldwide. A toilet or lavatory that works by gravity (that is, not assisted by pressure) is a device with which more water is consumed in homes, representing up to 40% of the domestic consumption of this resource. In order to promote a reduction in water consumption, international regulations have established limits to the allowable volume of water to be used for each discharge to empty a toilet. Thus, in 1994 NOM-CNA-009 was issued, which establishes that toilets manufactured and / or marketed in our country must discharge a volume less than or equal to 6 L; this rule is aligned with current international standards.[0003]But awareness regarding the care of the environment an...

AI Technical Summary

Benefits of technology

"The present invention is about an anti-sedimentation tank for an ecological toilet that can use previously used greywater containing organic and inorganic solid and / or semi-solid residues. The tank has an anti-sedimentation member inside it that prevents sediments from forming on the flat bottom of the tank. The tank has a modified shape that increases the entrainment force of the water that entrains any residue and prevents the formation of sediments. The tank can be installed in a conventional toilet and can also be used in a water-saving system that combines a washbasin with a toilet without requiring the toilet tank to be discharged."

Problems solved by technology

When the water passes through the plurality of openings, it wets the entire perimeter of the toilet bowl.

A disadvantage of the toilets described in the abovementioned patents resides in the fact that they were developed to comply with the criteria expressed in current international regulations and ensure good operation in toilets with a 6-L discharge.

However, this technology has the drawback of not being useful or efficient when one wishes to reduce the toilet discharge volume from 6 L to, for example, 4 L, without having to drastically and integrally modify its hydraulic design or its principles since, in order to achieve a reduction in water consumption of this magnitude, it is necessary to redesign all of the components of the toilet, as well as the way they interrelate to each other.

However, this type of toilet has two serious problems.

The first problem consist of the fact that the water used in a washbasin or other sources contains semi-solid and / or solid wastes (such as food residues, small pieces of soap, soapy water, toothpaste residues, shaving residues, hairs, etc.) that are stored in the toilet tank together with the water which will then be reused upon flushing the toilet to clean the toilet bowl and flush the waste therein, causing sedimentations and / or encrustations inside of the tank.

This problem originates because tanks are usually cube-shaped, with a flat bottom, leaving a reservoir caused by the difference in levels between the bottom of the tank and the lip of the discharge valve.

In addition, the same vitreous coating used for the external finish of the bathroom appliances is not applied to the internal surface of conventional toilet tanks, which has the drawback of the inside of the tank not being sanitary and, due to the porosity of its internal surface, it also provides much greater adherence for the impurities contained in the water.

However, when the water with which the tank is replenished has previously been used in the washbasin (as occurs in some of the water-saving systems described), said water contains both inorganic and organic semi-solid and / or solid wastes, and the formation of sediments can cause a problem that can be as severe and risky as bad odors and foci of contamination or infection resulting from the decomposition of the organic material.

Another drawback of this type of water-saving system that combines a toilet with a washbasin resides basically in the fact that in order to have a flow of water in the washbasin and for said flow to be stored in turn in the toilet tank for reuse, it is necessary to activate the toilet lever even when it does not need to be cleaned.

In other words, if a user wishes to use the washbasin to wash his hands or mouth, the user must necessarily first activate the toilet's discharge lever to initiate the flow of water in the washbasin, which represents an unnecessary waste of water.

The other problem presented by this type of modified toilet is that the semi-solid and / or solid wastes entrained from the tank obstruct the orifices in the rim of closed-rim toilet bowl, through which the water flows to wash the walls of the toilet bowl's bowl, since these orifices are relatively narrow (between 0.16 cm and 0.0793 cm in diameter ( 1 / 16 and 1 / 32 inch)), causing the toilet to be incapable of managing and / or disposing of the liquid, solid and / or semi-solid wastes that are stored in the tank, which come from a washbasin with which said tank is interconnected.
