TECHNICAL FIELD

The present invention is related with the bathroom furniture manufacturing industry, such as bathtubs, washbasin, bidets, toilet, among others. Particularly it relates to the manufacture of toilet bowls with a structure that allows for proper cleaning of the inside of the toilet when it is finished using, dragging efficiently solid and liquid wastes.

BACKGROUND

For the dragging of waste into the toilet bowl, there has always been the siphon effect a certain amount of water was discharging and this increased the height of the mirror of water in the front of the water ramp, and the time came that, by the principle of communicating vessels, the height of the water mirror of the back of the trap was increase. When the height exceeds and with the speed of feeding the water, the siphon principle is presented, dragging the solid and liquid waste.

Nowadays, in addition to the siphon effect, in some toilets comprise a water outlet coming from the feed, which debouch in front of the lower part of the water mirror of the bowl of the toilet bowl. When the jet exits, it pushes all wastes into the water trap and propels the siphon effect.

Currently there are various designs that try to reduce the volume per discharge. There are, for example, Flux Cups such as American Standard Cadet Flux, Kohler k-4405, Vienna EL Flux de Lamosa, Jazmin Flux de Cato, which handle a flush of 4.8 Liters per discharge Lpd.

The characteristics of this products are: Cadet discharge 4.8 Lpd, has a 2⅛″ trap; K-4405, handles 4.8 Lpd, has a 2¼″ trap; Vienna EL handles 4.8 Lp and has a 2¼″ trap; Jazmin 4.8 Lpd, has a 1⅞″ trap; Flux toilets like Orion and Kohler, do not have Jet; Crane Neuday has inverted the jet and the trap with a constant flow that helps the eviction at the back part of the bowl.

Baby Devour from American Standard has his Jet inside the trap and ELE BAT from Lamosa concentrates an abundant flow in the front.

All of these work with a bowl cleaning with holes hidden in the seat (upper edge) and have convenience arrangements for washing the inner surface of the bowl.

There are several mechanisms to achieve that with a smaller volume, a discharge cleans the bowl perfectly and drag the waste efficiently. Some of these mechanisms are supported at the top where the water is released for operation. Others have to do with the conformation of the lower part including the bowl and the water trap.

In U.S. Pat. No. 4,499,617, there is disclosed an insertable landfill structure for a lavatory including a cylindrical valve, with an opening through the cylinder perpendicular to and passing through its axis; Rotating and externally controlled in such a way that in one position it allows the liquid waste to pass through a passageway in the toilet flush and when it is rotated approximately 90°. Close completely the step in the landfill by forcing the rinsed material for continue the conventional path on the top of the landfill.

In U.S. Pat. No. 5,933,880, Huang, discloses a bowl assembly that include primarily a seat section, a base and a valve cap assembly. When the discharge control member is activated, the valve cover opens. The water from the water source will flow through the water passage of the seating section and a bowl-shaped space. The water will then flow horizontally through a valve port and then flow through a drainage passageway of the base and downward flows outward. Conversely, when the discharge control element is not activated, the valve cover is closed. Under such circumstances, the water from water source will not flow outward and the valve cover will block the valve hole to isolate the drain passage. Therefore, the toilet bowl can save more water, can be fixed on a wall, can be assembled easily, and can be easily cleaned.

The problem with the state of the art is that it requires mechanisms that can easily be damaged, requiring constant maintenance.

SUMMARY

One object of the invention is to achieve a structure or conformation which allows the internal walls of the toilet to be completely cleaned with a discharge of less than 4.8 Lpd.

Another objective is to achieve the complete evacuation of the waste with the discharge pressure supplied by 3.5 L.

Another objective is to make possible a bowl conformation which, in addition to the above objectives, also ensures that the operation does not affect the aesthetic design of the toilet, since comfort cannot be disregarded by operation.

Still another objective is to provide our bowl with the diameters of water flow to be able to make the discharge efficient, with the conditions indicated in the previous objectives.

The present invention mainly favors the saving of water, which is indispensable on the planet. Offering a discharge system with a consumption of 3.5 Liters per discharge (Lpd).

In addition to being water-saving with the same system, and so is in energy.

No new elements are implemented, which may complicate the production of the toilet bowl. Only a modification in the design of certain components such as the trap, the number of perforations in the top of the bowl (RIM) and exit of the Jet. Also the siphon was modified to carry the discharge of the solid waste properly. To begin with, the siphon tube has in the front a series of curves with gentler slopes, in the back has formed two steps, one upper and, where ends the first curve of the siphon and another near the end, where the tube discharge in the drain. This invention creates a movement of the cleaning flows of the inner surface of the bowl, which helps the movement of waste contained in the standing water for its early arrival into the trap.

This new design implemented for bowl flow, concentrates the flow mainly in the jet to eliminate the waste and the water through the trap, this type of discharge is designed calculating a necessary amount of water, which is divided for the cleaning of the bowl to the conduit with upper perforations that wash the walls of the bowl, and another portion of water from the lower perforation intended for eviction of the waste, which leads to a water saving and a powerful and efficient evacuation of Waste.

When the diameters of the trap, and shape of the Jet are well calculated, the water consumption is optimized. Which helps a significant saving of water.

Our toilet includes a large diameter Q trap that allows the easy eviction of waste. Besides having a classic design, not so high, and with diameters varied throughout for an acceleration of eviction of the stagnant water with its waste.

It also has an important step (sub-surface) above the exit of the Jet, in order to quickly dislodge stagnant water with debris. In this way the water from the Jet drags more easily the stagnant water (water mirror). And a convenient inclination in the 28 perforations hidden for an anti-clockwise movement that allows the movement of the residues inside the trap.

On the other hand, another aspect that takes into account the present invention is the necessity that is presented when the user of the toilet has a physical difficulties (locomotors). With this ailment, the user has problems to bending down too much, then a furniture that has more height to diminish this movement of crouching, facilitates the use of the toilet by this type of people.

The question now is to determine where the elongations will be made so that the toilet bowl is higher, and it was found that an elongation in the tube that ends in the drain, and an elongation in the front of the bowl, achieves the elongation of the same Without modifying their performance and facilitating the use by people with problems to bend down too much.

DETAILED DESCRIPTION

For a detailed description, we will support in the figures in order to make this description more comprehensible and with the level of clearance.

FIG. 1 illustrates a vertical cut in the longitudinal direction of the bowl displaying the inner side of the bowl's basin.

As can be seen from this figure, the discharge water entry 1 over the distribution chamber 2. In the chamber there are two exits, one is exit 3 that feeds the rim with the 28 orifices, 6 ellipsoidal, and the other is exit 4 that feeds two branches that surrounds through the inner side of the basin's wall 7 in order to come to disgorge in the flux 5 that is the stream exit that will push the wastes towards the exit of the water trap 8. This water trap is made to avoid that the drainage gases invade the bathroom space. Having this trap the water mirror 9, due to the principle of communicating vessels in the right arm of the trap it is had the same level 10 and it's until this point that the drainage gases will arrive.

The hydraulic design of a toilet bowl is an activity that does not respond to the preset rules, but responds to the experience of a designer and is selected with a heuristic method. The design of the present bowl displayed an interesting performance in terms of the cleaning of the basin and the dragging of the solid wastes into the drain.

A change in any of the elements that integrate the bowl such as: number, dimensions and the formation of the holes or conducts in the rim will indicate changes difficult to foresee. Having to change simultaneously the dimensions and formations of the pipes that feed the bowl's flux.

In these conditions it has been found that there must be a relation between the diameter of the water entry 1 and the exits of the water distribution chamber 3 and 4 and particularly the diameter relation of the exits towards the rim and into the flux. It has been found that the best relation between the rim's exit and the flux's exit is between 0.3 and 0.4. For example, the exit's diameter to the rim may be 9 mm and the one of the flux's exit would have to be 25 mm.

Now, with respect to the tube that forms the water seal in the back side of the bowl, this forms a loop 11 for it to undertake the siphon effect when the water flush is activated. The water level in the basin and in the seal tube rises until it reaches the maximum level and then goes down violently generating a vacuum pressure in the tube and this absorbs the content of the lower part of the basin. This is the siphon effect, and this effect is increased by the flux's stream in the inferior side, increasing the impulse of the wastes.

After this loop the tube presents two curves towards the basin forming two steps, a superior 12 and an inferior 13 just before it disgorges in the exit into the drainage. Surprisingly this staggering has improved the waste discharge into the drain. The superior step is not entirely straight or completely horizontal as the lower one is, but it is a brake that would normally be expected to hinder the solid and liquid waste flow, but nevertheless it improves such flow.

The basin 7 normally includes the water trap that due to the principles of communicating vessels keeps an amount of water in the rear and it is what prevents the gas return from the drain. The water mirror 9 has the same level as the water mirror 10 keeping a water trap 8.

When it is required that the bowl has a greater height, for example when the user is going to be a person with locomotor problems which retrain him to bend to far due to the atrophy of certain muscles, it is needed that the design is enlarged without a detriment in the hydraulic performance of the bowl.

In other of the favorite modalities of the present invention, the section of the tube that disgorges in the drainage may be elongated between the superior and the inferior steps, making the lengthening of the corresponding elements such as the conducts that lead the water of the distribution chamber to the jet.

It is clear that other elements present in the bowl must be elongated as well, but the rest of the elements in the hydraulic system and the drainage remains the same as well as the performance.

The FIG. 2 displays the superior face of the A-A cut, the pierces 6 of the water streams that will sweep the surface of the basin for its cleaning. This pierces are formed during the process so called punched out and consists in introducing a cylindrical body into the mass of the still friable material. Being introduced in an inclined manner with an angle of around 40° or 50°. The orifice presents an ellipsoidal formation and the conduct formed has a tilt so that the formed stream will concur in a zone as high as possible of the basin and with such inclination it will form an enveloping when the two forces come into play in the stream, gravity and outlet pressure, forming a curtain instead of two separate streams.

In this FIG. 2 it may be appreciated the elements 1, that consists in the water entry to the distribution chamber 2 and the exit 3 into the holes of the rim 6. Although in this view it's not noticed, the holes of the rim are ellipsoidal even though they are made with a cylindrical perforating punch. When the paste from which the toilet is made is still pliable, this perforating punch with a diameter of around 4 and 6 mm applied with a tilt between 40° and 50° originates a conduct with this incline and an exit with an ellipse form and has a larger diameter x2 between 5 and 7 mm and a smaller diameter x3 between 4 and 6 mm. Being inclined, the conduct formed by this punch, the water stream formed is also inclined and its directed to the wall of the basin from the superior part, carrying out the soaking more efficiently.

In other words the ellipsoidal holes included in the lower wall of the rim and the inclination of the punch is such that the stream comes out and is directed towards the wall of the basin in the corresponding zone of the neighbor holes of each exit orifice. In one of its preferred modalities the exit has a larger diameter x2 of 6 mm and a smaller diameter x3 of 5 mm or less. In one of the preferred modalities the rim includes in its entire periphery 28 conducts as the one described.

The encircled area by the circle c is seen with a better detail in FIG. 5.

FIG. 3 illustrates a downward view of the cut in the horizontal plane A-A of the bowl, with the water flow pass to the lower part. In this view it can be appreciated the distribution chamber 2, the exit 3 towards the jet 5 and the basin 14; the exit 3 connects with a couple internal conducts that surrounds the basin and disgorges in flux 5. The diameter of the flux has already been discussed in the detailed description of FIG. 1. Since we reiterate the relation of the diameter in exit 3 with respect to the diameter of exit 4, will condition the amount of water that will be conducted to the holes of the rim and the one that will be conducted to the flux. This conditioning will make that both the sweeping of the interior surface in the basin as the dislodge of the solid and liquid wastes in the bowl.

It is already mentioned in the description of FIG. 1 the relations of the diameter that achieve the proper flow of the water currents to clean the inner surface of the basin and efficiently dragging the solid and liquid wastes.

FIG. 5 illustrates the detail of the holes 6 in the rim 15 with its tilt that makes the formed stream to have an improved dragging effect.

In this cut it is displayed the inclination of the orifice to direct the provoked stream to the upper part of the inner surface of the basin.

However there is another orthogonal inclination to this one, namely at 90 degrees, and that makes that beyond to directing the stream toward the upper part of the basin, it would also be directed with a lateral tilt so that with the strength with what it exits the orifice and the effect of gravity it is formed a curtain that completely sweeps the surface of the basin, Without leaving surface without sweeping that would be the case when they are vertical jets that are formed by the orifices of the rim.

FIG. 5 illustrates the detail of the holes in the rim with its inclination that makes that the formed stream has an improved dragging effect. The punch, namely, the instrument with which the holes are made has a diameter between 4 and 6 mm that by an inclination between 40° and 50° it originates a conduct with this inclination and an exit with an ellipse form, with a larger diameter x2 between 5 and 7 mm and a minor diameter x3 between 4 and 6 mm.

The invention has been sufficiently described so that a person with medium knowledge in the subject may reproduce and obtain the results mentioned in this invention. Nevertheless any skillful person in the field of technology matter of the present invention may be able to make modifications not described in the present application, however the application of this modifications in a certain product or its manufacturing process it would be required form the claimed matter in the following claims. Such structures should be comprehended within the scope of the invention.
