Definitions

  • This invention relates to water closets (WC), also known as toilet bowls.
  • the modem western WC requires the user to sit on it during use.
  • squatting while defecating or urinating is a common practice.
  • Studies have shown that adopting the squatting posture during elimination of bodily wastes has health benefits.
  • persons with disorders of the knees or the back for example in elderly persons, may be unable to adopt a squatting posture.
  • a possible method to reduce splashing is by having the water level to be at an appropriate level below the anus of the user, usually not too low. This is achieved by designing the weir part of the S-bend at a high level.
  • the S-bend has to be filled sufficiently quickly with a large amount of water in order to initate siphon action in the S-bend, which then sucks out waste in the bowl.
  • pressure to conserve water has forced designers to reduce the previously large amount of water required to initiate siphon action, by using ever larger flush valves in the cistern or using pressurised flushing systems.
  • Working in contradiction to this desire to conserve water is the need to have a S-bend with a large diameter to reduce the risk of blockage: a large diameter S- bend requires more water to initiate siphon action.
  • WCs which appear like a normal western sitting WC with wing-like foot rests extending from each side of its rim.
  • the level of the foot rests is approximately at sitting height.
  • climibing onto the foot rests is an uncomfortable and precarious act.
  • the raised pedestal-type squatting WCs from Thailand
  • WCs cannot be used in the sitting posture because the height of the WC pan is too low.
  • any shifting of the feet while taking up the squatting posture has the risk of slipping and falling off the foot rests onto the floor or into the toilet bowl.
  • the regular Asian WC whose foot placement is at floor level. This is also not ideal as a person walking about in the toilet, especially in poor lighting, risks slipping and falling into the WC pan.
  • the object of the invention is to provide a WC that overcomes the imperfections of existing sitting, squatting and combination sittting and squatting WCs.
  • the invention shall:
  • Figure 1 is the overall view of the preferred embodiment of the present invention, with one of its foot rests show partially cut-away.
  • Figure 2 is a sectional side view of the above embodiment, with a user in the preferred squatting posture, facing the front end of the WC with the cistern shown unsectioned.
  • Figure 3 is a detailed section view of the rim flush outlet region.
  • Figure 4 is a sectional side view with a user in the alternative squatting posture, facing the rear end of the WC.
  • Figure 5 is a view showing the seat in the lowered position with a user in the usual sitting posture facing the front end of the WC.
  • the WC of the present invention consists of an elongated receptacle 10 similar in ratio of length to width to an eastern squatting-type WC. Additionally, there are shrouds 11 and 12 on each end of the receptacle 10 to contain urine spray. With the said shrouds being installed at boths ends means that the WC can be used when squatting facing either end.
  • a foot rest 14 Along each side of the receptacle 10, a little lower than its side rim 13, is a foot rest 14.
  • the said foot rest are shaped like the outline of two footprints placed facing opposite directions heel-to- heel, for ergonomics as well as to indicate to users their intended use.
  • the level of the said foot rests is such that when a user squats on them, the side rim 13 of the receptacle 10 is of sufficient height to prevent the feet from slipping into the receptacle 10.
  • One of the foot rests 14 is shown partially cut-away to reveal a cistern 15.
  • the foot rests 14 are designed as independent units separate from the central unit 9 containing receptacle 10.
  • the central unit 9 is substantially permanently installed onto the floor of the bathroom, with its trap outlet 8 properly sealed.
  • the cistern 15 and various mechanisms related to flushing are installed and/or adjusted.
  • the two foot rests are installed, in a removable manner, to provide access in future.
  • other embodiments employing other means of providing access to cistern 15 remain within the scope of the present invention.
  • the receptacle 10 at the rear end is the S-bend 16, which remains filled with water after flushing, thus forming a water seal against foul odours from the sewer.
  • the weir 17 of the S-bend is of such a level that the water level 18 after flushing is not too much lower than the user's anus when he is squatting on the toilet bowl. This reduces splashing during defecation.
  • Figure 2 also shows the user adopting the preferred squatting posture facing the front end of the WC. This posture is familiar to South East Asian squat toilet users. It is apparent that the stools will drop into water, which will quickly seal off fouls odours from them.
  • the cistern 15 for storing flush water is located below the foot rest 14 and the receptacle 10.
  • the flow of flush water from the cistern 15 is controlled by flush valve 22, immediately adjacent to the siphon jet entrance 20, hence improving the speed of initiating siphon action, thus conserving water. It is apparent that the placement of the cistern 15 in such a low position means that the elevational head of the water in the cistern will be insufficient for flushing. To overcome this, the cistern 15 must be fed from a pressurised water supply, which is almost universally available in any modern home.
  • the pressurised water supply will fill the cistern 15, trapping air in its upper part to such a point where the pressure in the cistern is equal to the static pressure of the supply.
  • the flush valve 22 is opened and the pressurised water in the cistern 15 is discharged quickly through the siphon jet entrance 20 into the S-bend 16, thus quickly initating the siphon action.
  • the volume of water discharged during each flush is controlled by proper design of the flush valve. While the present embodiment shows the cistern as a separate unit, it is to be understood that the alternative design of having the cistern integral with the WC remain within the scope of the present invention.
  • FIG 2 Also shown in figure 2 are two channels 23 and 24 for directing water to the front rim 25 and back rim 26 of receptacle 10 respectively.
  • these channels 23 and 24 can be supplied with water separately from the cistern 15. During flushing, water though them may be turned on first to clean the interior of receptacle 10, after a short delay which the flush valve 22 opens to initiate siphon action, subsequently which they remain on for a short while after the siphon action breaks in order to refill the S-bend.
  • Another possibility is to perform a water saving partial flush by turning on the water in the flush channels 23 and 24 only without opening flush valve 22.
  • the said channels are supplied with water via the same flush valve 22.
  • Figure 3 shows the option using a water nozzle 27 over the outlet of flush channel 23.
  • this option may also be employed at the outlet of flush channel 24.
  • This option eliminates the need for a water channel and water outlet holes in the front rim 25, side rims 13 and back rim 26, which requires an additional process during the manufacture of the WC and is a location of dirt accumulation.
  • the nozzle is made of a material that can be formed accurately during manufacture, for example, injection moulded plastic, so that the water spray can be accurately formed to cover the entire inner surface of receptacle 10 without missing any area or to have the desired flow pattern.
  • a relatively larger diameter water stream can be made to flow along the underside of the rims 25 and 13 so that sufficient water is available to arrive at the centre part of receptacle 10.
  • a relatively thinner film of water flow can be made to flow over other parts of the receptacle.
  • a larger water stream can also be made to flow along the lowermost part of receptacle 10 to hydraulically push stools (if any) into the S- bend.
  • the nozzle 27 as shown is removable for detailed cleaning. It may also be desirable to make the nozzle with a material that floats so that if it accidentally drops into the WC, it can be recovered easily.
  • Figure 4 shows a user adopting the alternative squatting posture facing the rear end of the WC.
  • This posture is familiar to East Asian squat toilet users. It is apparent from this figure mat the stools will land on the substantially dry part 28 of receptacle 10.
  • this method of use does not seal off foul odours from the stools, it is useful when stool observation or collection is desired. Additionally, in the case of diarrhoea, this method of use allows the liquid stools to land on a concave and sloping surface very close to the anus, thus reducing or even eliminating splashing. The reduction of splashing can also be assisted by turning on the water flow in the channel 23, so that a film of fast flowing water carries the stools away as they land.
  • Figure 5 shows the toilet seat 29 in the lowered position. Due to the presence of shrouds 11 and 12, the seat height is generally above the level of the said shrouds and hence is at a comfortable sitting height.
  • the seat may have suitable numbers of vertical webs 30 on each side which fit on top of side rim 13 to support the weight of the seated user.

Abstract

L'invention concerne des toilettes ou une cuvette de toilettes utilisable soit : 1 ) en position assise, 2) soit en position accroupie avant, soit 3) en position accroupie arrière. Les toilettes se composent d'un réceptacle allongé (10) identique en termes de rapport longueur/largeur à des toilettes à la turque, avec des flasques (11) à chaque extrémité pour recevoir les jets d’urine et des repose-pieds sur chaque côté, à un niveau légèrement inférieur au récipient, mais à une hauteur au-dessus du sol offrant un certain confort d'utilisation lorsque l'on monte sur les repose-pieds. Le volume en dessous du récipient et des repose-pieds est utilisé pour un réservoir, alimenté par de l'eau sous pression normale, de sorte que la source d'eau de chasse soit proche de l'entrée du jet du siphon au niveau de la partie avant de la courbure en S. Un siège articulé, d'une épaisseur/hauteur appropriée reposant sur le réceptacle lorsqu’il est déplié, forme une surface d'assise annulaire convenablement haute.
