Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of Mexican Patent
Application No. MX/a/2017/007561 filed on Jun. 9, 2017, which is
incorporated by reference in its entirety in this disclosure.
TECHNICAL FIELD
[0002] 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
[0003] 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.
[0004] 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.
[0005] 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.
[0006] The characteristics of this products are: Cadet discharge
4.8 Lpd, has a 21/8'' trap; K-4405, handles 4.8 Lpd, has a 21/4''
trap; Vienna EL handles 4.8 Lp and has a 21/4'' trap; Jazmin 4.8
Lpd, has a 17/8'' 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.
[0007] Baby Devour from American Standard has his Jet inside the
trap and ELE BAT from Lamosa concentrates an abundant flow in the
front.
[0008] 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.
[0009] 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.
[0010] 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.degree.. Close completely the step in the landfill by forcing
the rinsed material for continue the conventional path on the top
of the landfill.
[0011] 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.
[0012] The problem with the state of the art is that it requires
mechanisms that can easily be damaged, requiring constant
maintenance.
SUMMARY
[0013] 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.
[0014] Another objective is to achieve the complete evacuation of
the waste with the discharge pressure supplied by 3.5 L.
[0015] 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.
[0016] 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.
[0017] 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).
[0018] In addition to being water-saving with the same system, and
so is in energy.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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.
[0023] 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.
[0024] 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.
[0025] 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.

[0031] In order to provide the description of the enable feature,

DETAILED DESCRIPTION
[0032] For a detailed description, we will support in the figures
in order to make this description more comprehensible and with the
level of clearance.
[0033] FIG. 1 illustrates a vertical cut in the longitudinal
direction of the bowl displaying the inner side of the bowl's
basin.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] 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.degree. or
50.degree.. 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.
[0045] 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.degree. and 50.degree. 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.
[0046] 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.
[0047] The encircled area by the circle c is seen with a better
detail in FIG. 5.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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.degree. and 50.degree. 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.
[0054] 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.
