Definitions

  • 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.
  • 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.
  • 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.
  • 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 spring arrangement is provided between the first support plate [128] and the second support plate [130].
  • the spring arrangement includes a couple of support studs [134], a couple of locknuts [136], and a couple of spring members [138], installed between the first support plate [128] and the second support plate [130].
  • the support studs [134] and the locknuts [136] maintains a default length of the spring members [138], to maintain a default distance between the first support plate [128] and the second support plate [130].
  • the spring members [138] maintain the second support plate [130] towards/ proximal the first support plate [128], to maintain trapway [118] in the constricted state. Thereby, by default, the spring members [138] of the trap mechanism [120], maintains the trapway [118] in the constricted state.
  • the fluid connection facilitates sucking of air from the bottom chamber [146] of the cylinder [140], as the flushing operation is performed by the flush tank [114] of the flushing arrangement [104].
  • sucking of air 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 flushing operating conditions.
  • the fluid connection facilitates supply of air to the bottom chamber [146] of the cylinder, as the flushing operation is released by the flush tank [114] of the flushing arrangement [104].
  • Such supply of air enables movement of the second support plate [130] towards/ proximal to the first support plate [128], and thus operating the trapway [118] in the constricted state in the normal operating conditions, namely before/ after flushing operating conditions.
  • An air spring [150] is also provided in fluid communication to the bottom chamber [146], to temporarily store air within itself during sudden flushing operations/ emergency operating conditions.
  • a top chamber [144] of the cylinder [140] is fluidly connected to to an air bellow [152], via a check valve [154]. Further, a foot pedal [156] is connected to the air bellow [152].
  • the disclosed flexible trapway arrangement [106] discloses usage of a flat flexible trapway for connecting the water closet [102] to the drain line [110]. Specifically, a need of complex inverted U channel is avoided. Thus, usage of the flat trapway [118] requires low water head, and thus the flush tank [114] can be placed at relatively reduced heights. Thus, reducing the vertical space requirement of the toilet system [100].
