Definitions

  • the present disclosure relates to a flexible trapway arrangement for a toilet system according to the preamble of claim 1.
  • a typical toilet system includes a water closet and a flush arrangement.
  • the water closet is provided to receive faecal matter, when a user performs defecation thereon.
  • the flush arrangement is provided to supply water to the water closet, for removing faecal matter therefrom by pushing the faecal matter to a drain line with use of water pressure.
  • Water consumption optimization by a toilet system is also an essential requirement in addition to flushing.
  • the toilet system requires not only more water, but also higher water head, to flush the faecal matter.
  • the faecal matter is flushed to a drain line.
  • the higher water head here, relates to the potential energy of the water in the water storage tank of the flush arrangement.
  • the water storage tank of the flush arrangement is required to be positioned at greater heights relative to the water closet.
  • Such undesirable water consumption and higher water head requirements makes the toilet system less eco-friendly, functionally inefficient, and bulkier.
  • WO 2018/151361 A1 discloses a hydrolic waste water discharge device having a flexible waste water pipe which can be brought into a constricted state and into a dilated state. Two movable members above and below the pipe are arranged to exert force on the pipe for bringing same from the dilated state into the constricted State. This document discloses the features mentioned in the preamble of claim 1 and is considered to represent the closest prior art.
  • the water closet of the toilet system includes an integrally formed trapway, which connects the water closet to a drain line.
  • the trapway allows for exit of water and faecal matter from the water closet to the drain line.
  • the trapway is an inverted U-shaped channel including at least one vertical channel, to maintain a water seal of sump water in the water closet. While flushing, the faecal matter has to climb the vertical channel. This requires more flushing volume (more water) for flushing operations, which may be less eco-friendly. Additionally, such requirement of climbing the vertical channel requires a higher water head, which require the flush tank to be positioned at relatively higher heights. This may result in poor space-utilization. Such undesirable water consumption and higher water head requirements makes the toilet system less eco-friendly, functionally inefficient, and bulkier. Moreover, such Water closets with integrated complex structure of trapways is difficult to manufacture and require complex and expensive moulds for such manufacturing in an industrial set-up.
  • the present invention relates to a flexible trapway arrangement for connecting a toilet system to a drain line.
  • the trapway arrangement includes a trapway and a trap mechanism.
  • the trapway is made up of resilient material.
  • the trap mechanism is arranged with the trapway, and is adapted to operate the trapway in a constricted state and a dilated state. In the constricted state, the trap mechanism constricts at least a portion of the trapway to restrict a flow of components therethrough. In the dilated state, the trap mechanism dilates the trapway to allow a flow of components therethrough.
  • One object of the present invention relates to a flexible trapway arrangement for a toilet system, which provides an overall reduction in water consumption, thereby making the toilet system functionally more efficient, and providing space optimization provision of the water closet of the toilet system.
  • Yet another object of the present invention relates to a flexible trapway arrangement for a toilet system, which provides an overall reduction in water volume and water head needed for flushing process of the toilet system.
  • Yet another object of the present invention relates to a flexible trapway arrangement for a toilet system, which provides for an easy manufacturing process of the water closet of the toilet system.
  • Figure 1 illustrates a schematic of a toilet system [100], comprising a water closet [102], a flushing arrangement [104], and a flexible trapway arrangement [106].
  • the water closet [102] is a typical toilet bowl adapted to receive faecal matter [108], as a user perform defaecation thereon.
  • the water closet [102] is described to be a wall mounted closet, it may be obvious to a person skilled in the art that the water closet [102] may be a floor mounted closet as well.
  • the water closet [102] is in fluid communication with a drain line [110] via the flexible trapway arrangement [106], for enabling evacuation of faecal matter [108] therefrom when flushed by the flush arrangement [104].
  • the water closet [102] maintains a sump water [112] therein with use of the flexible trapway arrangement [106], which prevents sticking of faecal matter [108] in the water closet [102] as well as prevent the leakage of foul gases from the drain line [110] into the toilet area.

  • the flush tank [114] is a sealed pressurised tank fluidly connected to each of the water closet [102] and at least a component of the flexible trapway arrangement [106]. Therefore, flushing of water from the flush tank [114] results in sucking of air from at least one component of the flexible trapway arrangement [106].
  • the flush valve is further incorporated within the flush tank [114], and is adapted to allow/ restrict a supply of water from the flush tank [114] to the water closet [102]. Particularly, as a user presses a flush button, the flush valve allows the flow of water from the flush tank [114] to the water closet [102] and perform the flushing action. Additionally, as the flush button is released, the flush valve restricts the flow of water from the flush tank [114] to the water closet [102].

  • air is filled in the bottom chamber [146] of the cylinder.
  • the actuation mechanism [132] of the trap mechanism [120] is inoperative. Therefore, the spring member, with help of spring force, maintains the second support plate [130] towards/ proximal to the first support plate [128], to operate the trapway [118] in the constricted state.
  • the trapway [118] is constricted, and thus the sump water [112] is prevented from exiting to the drain line [110].
  • the sump water [112] is maintained within the water closet [102].

  • the flush tank [114] is the pressurized tank which forces/pressurizes water to flow from the flush tank [114] to the water closet [102]. Accordingly, as the water in the flush tank [114] starts reducing, the flush tank [114] sucks air from the bottom chamber [146] of the cylinder [140] of the actuation mechanism [132]. As the air is sucked from the bottom chamber [146], the piston [142] moves down from a top dead centre position to a bottom dead centre position within the cylinder [140].
  • the actuation mechanism [132] moves the second support plate [130] away/ distant from the first support plate [128], thereby shifting the trapway [118] from the constricted state to the dilate state.
  • the trapway [118] allows the components (sump water and faecal matter) in the water closet [102] to flow to the drain line [110], by way of water pressure of the flushing water.

  • the check valve [154] opens and air inside the air bellow [152] flows inside the top chamber [144] of the cylinder [140].
  • Such supply of air to the top chamber [144] of the cylinder [140] enables movement of the second support plate [130] away/ distal from the first support plate [128], and thus operating the trapway [118] in the dilated state in emergency operating conditions, upon manual intervention.
  • air on the bottom chamber [146] of the cylinder [140] is temporarily pushed into the air spring [150], and thus expanding the air spring [150].
  • the foot pedal [156] is released from pressure. With release of pressure from the foot pedal [156], the air in top chamber [144] of the cylinder [140] is released back to the air bellow [152].
  • the piston [142] moves upwards, thereby moving the second support plate [130] towards/ proximal to the first support plate [128]. This causes the trapway [118] to move from the dilated state to the constricted state.
