Definitions

  • the present invention relates to a new system of formation of sanitary ware, in particular shower trays, washbasins, bidets and water closets, wherein their shape already entails the presence of interior enclosed spaces and partitions already equipped with the height difference required for the formation of their own siphon system, so that the connection of the sanitary fixtures to the sewer pipeline effectively prevents the backflow of sewer gases, removing the considerable volume of the various trap devices, which at present must be connected to the said sanitary ware during installation.
  • One innovative feature of the present system is to entail, during the forming of the various sanitary ware, the formation of an intermediate partition between the water receiving chamber and a deposit chamber or alternatively a drain chamber of the same sanitary ware, which partition must have an edge either lower than the level of the chamber or lower than the drain hole rim of the fixture, so that the said edge of the intermediate partition is always immersed in a minimum quantity of standing water, which, not flowing out, creates an air seal between the drain area and the receiving area, thus preventing the backflow of sewer and drain gases in the receiving chamber, thereby spreading into the living areas, in compliance with the principle of a common siphon effect.
  • Sanitary bowls and sanitary fixtures or wares in general are intended for receiving and temporary retaining all water used either for personal hygiene, physiological needs and house cleaning and drainage of the resulting wastewaters into the pipelines leading to the sewer line.
  • DE 1 984 993 U discloses a washbasin an drain outlet and an overflow outlet meet a catch basin that is arranged under the washbasin itself and is connected with a drain conduit through a raised threshold that is arranged at a higher level with respect to the drain outlet and the overflow outlet to form a siphon.
  • GB 1 254 897 discloses a wash-hand basin that comprises a trap which comprises a member which is formed of the same material as, and integrally with, the basin and is divided into a descending part in an extension of the basin outlet aperture and a connected rising part by a partition; and a sleeve mounted inside the outlet aperture extension and removable through it.
  • a drain pipe is connected to the outlet of the trap and is formed integrally with the basin and of the same material.
  • CA 2 337 185 discloses a urinal structure mounted on a wall and including an outlet pipe in fluid communication with the basin of the urinal for disposal of waste water from the urinal during a flushing action.
  • the volume of the trap is not a problem for water closets, bidets and washbasins, which are provided with a pedestal, sufficiently high with respect to the floor, to place the said traps, contrarily such inconvenience is more evident, for example, with shower trays, where the drain outlet is approximately at floor level and where the trap must be fitted down the drain.
  • the most recent technology mainly indicated for the drainage of water from bathtubs or shower trays, entails the formation of a receiving chamber, to be fitted under the sanitary fixture during installation, whose edge is higher than the drain pipe joint, where the overflowing water is received and conveyed to the grey water drain pipe, as described in patents FR 2 800 261 and DE 103 06 120.
  • the inconvenience relating to the vertical volume of the trap is partially prevented, since the drainpipe can be basically positioned at rough floor level.
  • a further important object of the invention is to be entirely achieved at the formation stage of the sanitary ware, without further assembly or installation of any trap device.
  • a further object of the present invention is, in particular, to achieve suspended and wall mounted sanitary ware, without having to cover their base with a pedestal or furniture, and in any case evading the sight of trap and drain fittings.
  • Another object of the present system is to be suitable for any kind of sanitary ware, allowing its formation in shallow heights, fit for the creation of new ranges of sanitary fixtures, most of all the wall mounted types.
  • the present system can also be employed for sanitary ware placed quite far from the main drain, provided that the concrete floor slab is high enough to allow a proper pitch of the drainpipe.
  • a sanitary ware comprising a siphon system, said sanitary ware comprising an outer frame, at least one inclined partition, a receiving channel, a siphon chamber, a drain outlet arranged at a side of said siphon chamber, said siphon chamber communicating both with said receiving channel and said drain outlet, wherein said siphon chamber has a horizontal bottom formed by a bottom of said sanitary ware and an end of said inclined partition is spaced from said horizontal bottom by a distance that is smaller than a distance between a lowest point of said drain outlet and said bottom, so that said end is in use immersed in water.
  • a sanitary ware comprising a siphon system, said sanitary ware comprising an outer frame, at least one inclined partition, a receiving channel, a siphon chamber, a drain outlet arranged at a bottom of said siphon chamber, said siphon chamber communicating both with said receiving channel and said drain outlet, wherein said bottom is a horizontal bottom, an intermediate partition dividing said siphon chamber into a deposit chamber and a drain chamber communicating with each other, said deposit chamber communicating with said receiving channel, said drain chamber communicating with said drain outlet, an end of said inclined partition being spaced from said bottom by a distance that is lower than a height of said intermediate partition, so that said end is in use immersed in water.
  • FIG. 1 is a vertical view, according to the section plan I-I of the shower tray in FIG. 3 ;
  • FIG. 2 is a vertical view, according to the section plan II-II of the same shower tray in FIG. 3 ;
  • FIG. 3 is a top view and a partial cross-sectional view of an example embodiment of a shower tray according to the present invention
  • FIG. 4 is a vertical view, according to the section plan IV-IV of the washbasin or bidet in FIG. 5 ;
  • FIG. 5 is a top view and a partial cross-sectional view of an example embodiment of a washbasin or bidet according to the present invention.
  • FIG. 6 is a vertical view, according to the section plan VI-VI of the water closet in FIG. 7 ;
  • FIG. 7 is a top view of an example embodiment of a water closet according to the present invention.
  • a shower tray 1 substantially comprises a basic plane 10 , for instance square-shaped, which is tied together with an outer frame 11 , that sets its dimensions, and with two upper inclined planes 12 and 13 , each converging towards the mid-junction plane 14 .
  • a series of ribs or vertical supports 15 , 16 and 17 there is a series of ribs or vertical supports 15 , 16 and 17 , with the main function to support both inclined planes 12 and 13 , determining a series of enclosed watertight spaces, indicated with numbers 32 , 33 , 34 , 35 and 36 .
  • the inclined plane 13 presents a slideway or additional inclination 18 , which joins rib 17
  • the opposite inclined plane 12 presents a slideway or additional inclination 19 , having a fixed-height edge with respect to the basic plane 10 , as better described hereafter, forming a channel or receiving chamber 3 of the shower water which flows in from the same inclined planes 12 and 13 .
  • the drain chamber 21 is indeed provided with an outlet hole 23 , which therefore receives and drains the water overflowing from the aforementioned partition 22 to convey it to the grey water pipeline.
  • foul smells seeping up from the drain pipeline to the opening 23 and the drain chamber 21 , can not escape into the living area, because the layer of water standing in the deposit chamber 20 , seals the passageway from the said chamber 20 to the receiving channel 30 , by constantly immersing the end of the slideway 19 , thus granting the required siphon effect, with no need of common cumbersome exterior devices applied, in compliance with the main object herein specified.
  • the shower tray of FIG. 1 to 3 is also completed with a lower surface 37 which enables the laying, on the same shower tray 1 , of a plain or grid board, allowing the strict horizontal levelling of the user's bearing surface, besides facilitating the flow of the shower water from the inclined partitions 12 and 13 to the receiving channel 3 .
  • FIGS. 2 and 3 there is shown a first variant embodiment of the shower tray 1 with the horizontal arrangement of a drain outlet 23 ′ cut out of the outer frame 11 as illustrated for example with the dashed line.
  • the lower point of the hole rim 23 is set at a height level, with respect to the bottom 10 , which is equal to the height of the above described partition 22 , so that the presence of the same partition 22 becomes useless.
  • the deposit chamber 20 extends up to the rim of drain outlet 23 ′, nonetheless ensuring that the end of the slideway 19 is always immersed in the water of the deposit chamber 20 , thus achieving the required siphon effect.
  • the same siphon system is applied in the embodiment of either a washbasin, a sink or a bidet 101 , entailing the presence of a single inclined plane 112 , its dimensions being smaller than those of the shower tray 1 , at the same time its embodiment is easier because the above illustrated ribbings may be eliminated.
  • the drain outlet 123 is cut out at one side of the outer frame 111 , with the aim of further reducing the total height of the sanitary ware 101 for wall mounted use.
  • the arrangement of the drain outlet 123 at one side permits the removal of partition 122 , so as to form a single siphon chamber, which includes the deposit chamber 120 and the drain chamber 121 , since the lower point of such hole 123 delimits the level of the siphon water standing in the chamber 120 , although it must be higher than the end 119 of the inclined plane 112 and constantly grant the presence of a sheet of water at the level of the receiving hole 130 .
  • the same sanitary bowl 101 can be carried out, as an alternative, with the drain hole 123 ′ arranged at the bottom 110 , as exemplified with the dashed line in the same FIGS. 4 and 5 , complying with what has been previously described for the shower tray 1 , thus entailing the formation of two chambers, a deposit chamber 120 and a drain chamber 121 with an overflow partition 122 , according to the already described scheme.
  • a water closet 201 which, as the washbasin 101 , is represented with a side or lateral drain outlet 223 of black water, for wall-mounted application.
  • the level of the siphon chamber 220 - 221 is determined by the lower point of the drain hole 223 , provided that such level must be higher than the height of the span or passageway between the bottom 210 and the end 219 of the inclined partition 212 , in order to attain the required siphon effect.
  • the height of the passageway between the bottom 210 and the end 219 will have to be adequate and in any case bigger than the height required for the exemplified washbasin 101 , as well as the inclination of the partition 212 .
  • the arrangement of the drain outlet 223 ′ at the bottom 210 is also feasible for the water closet 201 , with the ensuing need of applying a partition 222 between the deposit chamber 220 and the drain chamber 221 , so as to ensure that the end 219 of the inclined partition 212 is always immersed in the water of the receiving chamber 230 and the deposit chamber 220 in compliance with the siphon scheme so far described.
  • a supply inlet 240 is provided for flushing water, with its own distribution chamber 241 and with outlet holes 242 , in compliance with any system of flushing water distribution.
  • This new technique consists basically in the tooling and shaping of the various aforesaid parts of each sanitary fixture, namely the bottom, the side partitions, the inclined partitions, etc., cut out of slabs or various profiles of special resins like Corian® and then in their positioning and fixing, by means of proper adhesives, according to an established technique, well-known in various fields of use, that in this field enables the embodiment of a siphon system for the sanitary fixtures achieved according to the aforesaid specifications, which is absolutely innovative and original.
  • the embodiment of the siphon system of sanitary ware so far illustrated is meant as merely exemplifying and non-limitative, not only for the possibility of variation in relation to the arrangement of the drain outlet 23 , 123 , 223 either at the bottom 10 , 114 , 210 or on the side surface 11 , 111 , 211 , but also for further possible embodiments in relation to the shape of the various sanitary ware 10 , 110 , 210 .
  • the inclined ends 18 and 19 of the planes 12 and 13 can be orthogonal with respect to the same planes 12 and 13 or with respect to the bottom 10 , moreover the blind areas or those points not reached by the water 32 , 33 , 34 , 35 and 36 can vary in number according to the variation of the ribs 15 and 16 or equivalent points of support of the inclined planes 12 and 13 , in addition the said areas can be filled or padded, for example, with a suitable polyurethane foam or equivalent material.
  • a board can be laid directly on the inclined planes 12 and 13 of the shower tray 1 , in addition an horizontal plane can be laid directly on the inclined plane 112 of the fixture 101 , provided that the said boards are equipped with inclined feet apt to ensure the horizontal levelling, preventing an unsanitary surfacing of standing water.
  • shower trays 1 can also be attained with watertight chambers 32 , 33 , 34 , 35 and 36 either bottomless 10 or with a pierced bottom 10 , for example, for embedding in the concrete floor slab where they should be anchored; at the same time shower trays 1 can also be achieved with a single inclined plane extending over the whole shower tray, providing that the end 19 is immersed in the deposit chamber 20 placed below.
  • the inclined partitions 112 and 212 of the sanitary fixtures 101 and 201 can be provided with a different inclination, even upright, in respect to the level of standing water in which they are immersed, and associated to feasible planes to which they can be hinged horizontally, to conceal the standing water and to grant major volumes of use of the fixture, like for example, kitchen sinks, at the same time the inclined partition 112 can be differently shaped, in order to increase the free volume at disposal of the basin, always providing that the ends 119 are immersed and enclosed between the receiving chamber 130 and the deposit chamber 120 of wastewater.
